**The U.S. Securities and Exchange Commission has not approved or disapproved of these securities. Further, it has not determined that this prospectus is accurate or complete. Any representation to the contrary is a criminal offense.**

 **SMALLCAP World Fund** 

**Investment objective** The fund's investment objective is to provide you with long-term growth of capital.

**Fees and expenses of the fund** This table describes the fees and expenses that you may pay if you buy, hold and sell an interest in Class 1 shares of the fund. **You may pay other fees, such as insurance contract fees and expenses, which are not reflected in the tables and examples below.** If insurance contract fees and expenses were reflected, expenses shown would be higher.

---

| | |
|:---|:---|
| **Annual fund operating expenses (expenses that you pay each year as a percentage of the net asset value of your investment)** | Class 1 |
| Management fee | 0.65% |
| Other expenses | 0.05 |
| Total annual fund operating expenses | 0.70 |
| Fee waiver\* | 0.05 |
| Total annual fund operating expenses after fee waiver | 0.65 |

---

\* The investment adviser is currently waiving a portion of its management fee equal to 0.05% of the fund's net assets. This waiver will be in effect through at least May 1, 2027. The waiver may only be modified or terminated with the approval of the fund's board.

**Example** This example is intended to help you compare the cost of investing in Class 1 shares of the fund with the cost of investing in other mutual funds.

The example assumes that you invest $10,000 in the fund for the time periods indicated and then redeem or hold all of your shares at the end of those periods. The example also assumes that your investment has a 5% return each year and that the fund's operating expenses remain the same. The example does not reflect insurance contract expenses. If insurance contract expenses were reflected, expenses shown would be higher. The example reflects the fee waiver described above through the expiration date of such waiver and total annual fund operating expenses thereafter. No sales charge (load) or other fees are charged by the fund upon redemption, so you would incur these hypothetical costs whether or not you were to redeem your shares at the end of the given period. Although your actual costs may be higher or lower, based on these assumptions your costs would be:

---

| | | | | |
|:---|:---|:---|:---|:---|
|  | 1 year | 3 years | 5 years | 10 years |
| Class 1 | $66 | $219 | $385 | $866 |

---

**Portfolio turnover** The fund pays transaction costs, such as commissions, when it buys and sells securities (or "turns over" its portfolio). A higher portfolio turnover rate may indicate higher transaction costs. These costs, which are not reflected in annual fund operating expenses or in the example, affect the fund's investment results. During the most recent fiscal year, the fund's portfolio turnover rate was 51% of the average value of its portfolio.

**Principal investment strategies** Normally the fund invests at least 80% of its net assets in common stocks and other equity-type securities (such as preferred stocks, convertible preferred stocks and convertible bonds) of companies with small market capitalizations, including growth-oriented stocks. The investment adviser currently defines "small market capitalization" companies to be companies with market capitalizations within or below the capitalization range of companies included in the MSCI All Country World Small Cap Index or the Russell 2000 Index, measured based on the maximum market capitalization of companies in either index within the last 12 months. As of August 31, 2025, the largest company in the MSCI All Country World Small Cap Index had a market capitalization of approximately $25.9 billion and the largest company in the Russell 2000 Index had a market capitalization of approximately $20.9 billion. The market capitalization of the companies included in the MSCI All Country World Small Cap Index and the Russell 2000 Index will change with market conditions. The investment adviser has periodically re-evaluated and adjusted this definition and may continue to do so in the future. The fund may continue to hold securities of a portfolio company that subsequently appreciates above the small market capitalization threshold. Under normal circumstances, the fund will invest a significant portion of its assets outside the United States, including in emerging markets.

Prior to May 1, 2026, the fund was called Global Small Capitalization Fund.

The investment adviser uses a system of multiple portfolio managers in managing the fund's assets. Under this approach, the portfolio of the fund is divided into segments managed by individual managers.

The fund relies on the professional judgment of its investment adviser to make decisions about the fund's portfolio investments. The basic investment philosophy of the investment adviser is to seek to invest in attractively valued companies that, in its opinion, represent good, long-term investment opportunities. Securities may be sold when the investment adviser believes that they no longer represent relatively attractive investment opportunities.

**Principal risks This section describes the principal risks associated with investing in the fund. You may lose money by investing in the fund. The likelihood of loss may be greater if you invest for a shorter period of time.** 

*Market conditions* — The prices of, and the income generated by, the securities held by the fund may decline – sometimes rapidly or unpredictably – due to various factors, including events or conditions affecting the general economy or particular industries or companies; overall market changes; local, regional or global political, social or economic instability; governmental, governmental agency or central bank responses to economic conditions; levels of public debt and deficits; changes in inflation rates; and currency exchange rate, interest rate and commodity price fluctuations.

Economies and financial markets throughout the world are highly interconnected. Economic, financial or political events, trading and tariff arrangements, wars, terrorism, cybersecurity events, natural disasters, public health emergencies (such as the spread of infectious disease), bank failures and other circumstances in one country or region, including actions taken by governmental or quasi-governmental authorities in response to any of the foregoing, could have impacts on global economies or markets. As a result, whether or not the fund invests in securities of issuers located in or with significant exposure to the countries affected, the value and liquidity of the fund's investments may be negatively affected by developments in other countries and regions.

*Issuer risks* — The prices of, and the income generated by, securities held by the fund may decline in response to various factors directly related to the issuers of such securities, including reduced demand for an issuer's goods or services, poor management performance, major litigation, investigations or other controversies related to the issuer, changes in the issuer's financial condition or credit rating, changes in government regulations affecting the issuer or its competitive environment and strategic initiatives such as mergers, acquisitions or dispositions and the market response to any such initiatives. An individual security may also be affected by factors relating to the industry or sector of the issuer or the securities markets as a whole, and conversely an industry or sector or the securities markets may be affected by a change in financial condition or other event affecting a single issuer.

*Investing in growth-oriented stocks* — Growth-oriented common stocks and other equity-type securities (such as preferred stocks, convertible preferred stocks and convertible bonds) may involve larger price swings and greater potential for loss than other types of investments. These risks may be even greater in the case of smaller capitalization stocks.

*Investing in small companies* — Investing in smaller companies may pose additional risks. For example, it is often more difficult to value or dispose of small company stocks and more difficult to obtain information about smaller companies than about larger companies. Furthermore, smaller companies often have limited product lines, operating histories, markets and/or financial resources, may be dependent on one or a few key persons for management, and can be more susceptible to losses. Moreover, the prices of their stocks may be more volatile than stocks of larger, more established companies, particularly during times of market turmoil.

*Investing outside the United States* — Securities of issuers domiciled outside the United States or with significant operations or revenues outside the United States, and securities tied economically to countries outside the United States, may lose value because of adverse political, social, economic or market developments (including social instability, regional conflicts, terrorism and war) in the countries or regions in which the issuers are domiciled, operate or generate revenue or to which the securities are tied economically. These securities may also lose value due to changes in foreign currency exchange rates against the U.S. dollar and/or currencies of other countries. Issuers of these securities may be more susceptible to actions of foreign governments, such as nationalization, currency blockage or the imposition of price controls, sanctions, or punitive taxes, each of which could adversely impact the value of these securities. Securities markets in certain countries may be more volatile and/or less liquid than those in the United States. Investments outside the United States may also be subject to different regulatory, legal, accounting, auditing, financial reporting and recordkeeping requirements, and may be more difficult to value, than those in the United States. In addition, the value of investments outside the United States may be reduced by foreign taxes, including foreign withholding taxes on interest and dividends. Further, there may be increased risks of delayed settlement of securities purchased or sold by the fund, which could impact the liquidity of the fund's portfolio. The risks of investing outside the United States may be heightened in connection with investments in emerging markets.

*Investing in emerging markets* — Investing in emerging markets may involve risks in addition to and greater than those generally associated with investing in the securities markets of developed countries. For instance, emerging market countries tend to have less developed political, economic and legal systems than those in developed countries. Accordingly, the governments of these countries may be less stable and more likely to intervene in the market economy, for example, by imposing capital controls, nationalizing a company or industry, placing restrictions on foreign ownership and on withdrawing sale proceeds of securities from the country, and/or imposing punitive taxes that could adversely affect the prices of securities. Information regarding issuers in emerging markets may be limited, incomplete or inaccurate, and such issuers may not be subject to regulatory, accounting, auditing, and financial reporting and recordkeeping standards comparable to those to which issuers in more developed markets are subject. The fund's rights with respect to its investments in emerging markets, if any, will generally be governed by local law, which may make it difficult or impossible for the fund to pursue legal remedies or to obtain and enforce judgments in local courts. In addition, the economies of these countries may be dependent on relatively few industries, may have limited access to capital and may be more susceptible to changes in local and global trade conditions and downturns in the world economy. Securities markets in these countries can also be relatively small and have substantially lower trading volumes. As a result, securities issued in these countries may be more volatile and less liquid, more vulnerable to market manipulation, and more difficult to value, than securities issued in countries with more developed economies and/or markets. Less certainty with respect to security valuations may lead to additional challenges and risks in calculating the fund's net asset value. Additionally, emerging markets are more likely to experience problems with the clearing and settling of trades and the holding of securities by banks, agents and depositories that are less established than those in developed countries.

*Liquidity risk* — Certain fund holdings may be or may become difficult or impossible to sell, particularly during times of market turmoil. Liquidity may be impacted by the lack of an active market for a holding, legal or contractual restrictions on resale, or the reduced number and capacity of market participants to make a market in such holding. Market prices for less liquid or illiquid holdings may be volatile or difficult to determine, and reduced liquidity may have an adverse impact on the market price of such holdings. Additionally, the sale of less liquid or illiquid holdings may involve substantial delays (including delays in settlement) and additional costs and the fund may be unable to sell such holdings when necessary to meet its liquidity needs or to try to limit losses, or may be forced to sell at a loss.

*Management* — The investment adviser to the fund actively manages the fund's investments. Consequently, the fund is subject to the risk that the methods and analyses, including models, tools and data, employed by the investment adviser in this process may be flawed or incorrect and may not produce the desired results. This could cause the fund to lose value or its investment results to lag relevant benchmarks or other funds with similar objectives.

Your investment in the fund is not a bank deposit and is not insured or guaranteed by the Federal Deposit Insurance Corporation or any other governmental agency, entity or person. You should consider how this fund fits into your overall investment program.

**Investment results** The following bar chart shows how the investment results of the Class 1 shares of the fund have varied from year to year, and the following table shows how the fund's average annual total returns for various periods compare with a broad measure of securities market results and, if applicable, other measures of market results that reflect the fund's investment universe. This information provides some indication of the risks of investing in the fund. Past investment results (before and after taxes) are not predictive of future investment results. Figures shown reflect fees and expenses associated with an investment in the fund, but do not reflect insurance contract fees and expenses. If insurance contract fees and expenses were included, results would have been lower. Updated information on the fund's investment results can be obtained by visiting capitalgroup.com/afis.

**Purchase and sale of fund shares** Shares of the fund are not sold directly to the general public. The fund is offered only as an underlying investment option for variable insurance contracts, and insurance company separate accounts and qualified feeder funds — and not the holders of variable insurance contracts — are the shareholders of the fund. Although the fund does not require a minimum amount for initial or subsequent purchases from insurance companies, your insurance company may impose investment minimums for your purchase of the fund.

You may sell (redeem) shares on any business day. You must sell (redeem) shares through your insurance company.

**Tax information** See your variable insurance contract prospectus for information regarding the federal income tax treatment of your variable insurance contract and related distributions.

**Payments to broker-dealers and other financial intermediaries** The fund is not sold directly to the general public but instead is offered as an underlying investment option for variable insurance contracts. The fund and its related companies may make payments to the sponsoring insurance company (or its affiliates) for distribution and/or other services. These payments may be a factor that the insurance company considers in including the fund as an underlying investment option in the variable insurance contract. The prospectus (or other offering document) for your variable insurance contract may contain additional information about these payments.

\* The investment adviser is currently waiving a portion of its management fee equal to 0.06% of the fund's net assets. This waiver will be in effect through at least May 1, 2027. The waiver may only be modified or terminated with the approval of the fund's board.

**Portfolio turnover** The fund pays transaction costs, such as commissions, when it buys and sells securities (or "turns over" its portfolio). A higher portfolio turnover rate may indicate higher transaction costs. These costs, which are not reflected in annual fund operating expenses or in the example, affect the fund's investment results. During the most recent fiscal year, the fund's portfolio turnover rate was 63% of the average value of its portfolio.

**Principal investment strategies** The fund invests primarily in common stocks in Europe and the Pacific Basin that the investment adviser believes have the potential for growth. Growth stocks are stocks that the investment adviser believes have the potential for above-average capital appreciation.

Normally the fund will invest at least 80% of its net assets in securities of issuers in Europe and the Pacific Basin. A country will be considered part of Europe if it is part of the MSCI European indexes, and part of the Pacific Basin if any of its borders touches the Pacific Ocean. In determining the domicile of an issuer, the fund's investment adviser will generally look to the determination of MSCI Inc. (MSCI) for equity securities and Bloomberg for debt securities. In certain limited circumstances (including where relevant data is unavailable or the nature of a holding warrants special considerations), the adviser may also take into account additional factors, as applicable, including where the issuer's securities are listed; where the issuer is legally organized, maintains principal corporate offices, conducts its principal operations, generates revenues and/or has credit risk exposure; and the source of guarantees, if any, of such securities. The fund may invest a portion of its assets in common stocks and other securities of companies in emerging markets.

Prior to May 1, 2026, the fund was called International Fund.

The investment adviser uses a system of multiple portfolio managers in managing the fund's assets. Under this approach, the portfolio of the fund is divided into segments managed by individual managers.

Investments outside the United States may also be subject to different regulatory, legal, accounting, auditing, financial reporting and recordkeeping requirements, and may be more difficult to value, than those in the United States. In addition, the value of investments outside the United States may be reduced by foreign taxes, including foreign withholding taxes on interest and dividends. Further, there may be increased risks of delayed settlement of securities purchased or sold by the fund, which could impact the liquidity of the fund's portfolio. The risks of investing outside the United States may be heightened in connection with investments in emerging markets.

*Investing in emerging markets* — Investing in emerging markets may involve risks in addition to and greater than those generally associated with investing in the securities markets of developed countries. For instance, emerging market countries tend to have less developed political, economic and legal systems than those in developed countries. Accordingly, the governments of these countries may be less stable and more likely to intervene in the market economy, for example, by imposing capital controls, nationalizing a company or industry, placing restrictions on foreign ownership and on withdrawing sale proceeds of securities from the country, and/or imposing punitive taxes that could adversely affect the prices of securities. Information regarding issuers in emerging markets may be limited, incomplete or inaccurate, and such issuers may not be subject to regulatory, accounting, auditing, and financial reporting and recordkeeping standards comparable to those to which issuers in more developed markets are subject. The fund's rights with respect to its investments in emerging markets, if any, will generally be governed by local law, which may make it difficult or impossible for the fund to pursue legal remedies or to obtain and enforce judgments in local courts. In addition, the economies of these countries may be dependent on relatively few industries, may have limited access to capital and may be more susceptible to changes in local and global trade conditions and downturns in the world economy. Securities markets in these countries can also be relatively small and have substantially lower trading volumes. As a result, securities issued in these countries may be more volatile and less liquid, more vulnerable to market manipulation, and more difficult to value, than securities issued in countries with more developed economies and/or markets. Less certainty with respect to security valuations may lead to additional challenges and risks in calculating the fund's net asset value. Additionally, emerging markets are more likely to experience problems with the clearing and settling of trades and the holding of securities by banks, agents and depositories that are less established than those in developed countries.

*Management* — The investment adviser to the fund actively manages the fund's investments. Consequently, the fund is subject to the risk that the methods and analyses, including models, tools and data, employed by the investment adviser in this process may be flawed or incorrect and may not produce the desired results. This could cause the fund to lose value or its investment results to lag relevant benchmarks or other funds with similar objectives.

Your investment in the fund is not a bank deposit and is not insured or guaranteed by the Federal Deposit Insurance Corporation or any other governmental agency, entity or person. You should consider how this fund fits into your overall investment program.

**Purchase and sale of fund shares** Shares of the fund are not sold directly to the general public. The fund is offered only as an underlying investment option for variable insurance contracts, and insurance company separate accounts and qualified feeder funds — and not the holders of variable insurance contracts — are the shareholders of the fund. Although the fund does not require a minimum amount for initial or subsequent purchases from insurance companies, your insurance company may impose investment minimums for your purchase of the fund.

You may sell (redeem) shares on any business day. You must sell (redeem) shares through your insurance company.

**Tax information** See your variable insurance contract prospectus for information regarding the federal income tax treatment of your variable insurance contract and related distributions.

**Payments to broker-dealers and other financial intermediaries** The fund is not sold directly to the general public but instead is offered as an underlying investment option for variable insurance contracts. The fund and its related companies may make payments to the sponsoring insurance company (or its affiliates) for distribution and/or other services. These payments may be a factor that the insurance company considers in including the fund as an underlying investment option in the variable insurance contract. The prospectus (or other offering document) for your variable insurance contract may contain additional information about these payments.

**Investment objectives, strategies and risks** 

**SMALLCAP World Fund** The fund's investment objective is to provide you with long-term growth of capital. While it has no present intention to do so, the fund's board may change the fund's investment objective without shareholder approval upon 60 days' prior written notice to shareholders. Normally the fund invests at least 80% of its net assets in common stocks and other equity-type securities (such as preferred stocks, convertible preferred stocks and convertible bonds) of companies with small market capitalizations, including growth-oriented stocks. This policy is subject to change only upon 60 days' prior written notice to shareholders. The investment adviser currently defines "small market capitalization" companies to be companies with market capitalizations within or below the capitalization range of companies included in the MSCI All Country World Small Cap Index or the Russell 2000 Index, measured based on the maximum market capitalization of companies in either index within the last 12 months. As of August 31, 2025, the largest company in the MSCI All Country World Small Cap Index had a market capitalization of approximately $25.9 billion and the largest company in the Russell 2000 Index had a market capitalization of approximately $20.9 billion. The market capitalization of the companies included in the MSCI All Country World Small Cap Index and the Russell 2000 Index will change with market conditions. The investment adviser has periodically re-evaluated and adjusted this definition and may continue to do so in the future. The fund may continue to hold securities of a portfolio company that subsequently appreciates above the small market capitalization threshold. Under normal circumstances, the fund will invest a significant portion of its assets outside the United States, including in emerging markets.

The fund may also hold cash or cash equivalents, including commercial paper and short-term securities issued by the U.S. government, its agencies and instrumentalities. The percentage of the fund invested in such holdings varies and depends on various factors, including market conditions and purchases and redemptions of fund shares. The investment adviser may determine that it is appropriate to invest a substantial portion of the fund's assets in such instruments in response to certain circumstances, such as periods of market turmoil. For temporary defensive purposes, the fund may invest without limitation in such instruments. A larger percentage of such holdings could moderate the fund's investment results in a period of rising market prices. Alternatively, a larger percentage of such holdings could reduce the magnitude of the fund's loss in a period of falling market prices and provide liquidity to make additional investments or to meet redemptions.

The fund may invest in certain other funds managed by the investment adviser or its affiliates ("Central Funds") to more effectively invest in a diversified set of securities in a specific asset class such as money market instruments, bonds and other securities. Shares of Central Funds are only offered for purchase to the fund's investment adviser and its affiliates and other funds, investment vehicles and accounts managed by the fund's investment adviser and its affiliates. Central Funds do not charge management fees. As a result, the fund does not bear additional management fees when investing in Central Funds, but the fund does bear its proportionate share of Central Fund expenses. The investment results of the portions of the fund's assets invested in the Central Funds will be based upon the investment results of the Central Funds.

The fund may also lend portfolio securities to brokers, dealers and other institutions that provide cash or U.S. Treasury securities as collateral in an amount at least equal to the value of the securities loaned.

Prior to May 1, 2026, the fund was called Global Small Capitalization Fund.

The fund relies on the professional judgment of its investment adviser to make decisions about the fund's portfolio investments. The basic investment philosophy of the investment adviser is to seek to invest in attractively valued companies that, in its opinion, represent good, long-term investment opportunities. The investment adviser believes that an important way to accomplish this is through fundamental analysis, which may include meeting with company executives and employees, suppliers, customers and competitors. Securities may be sold when the investment adviser believes that they no longer represent relatively attractive investment opportunities.

The investment adviser may consider environmental, social and governance ("ESG") factors that, depending on the facts and circumstances, are material to the value of an issuer or instrument. ESG factors may include, but are not limited to, environmental issues (e.g., water use, emission levels, waste, environmental remediation), social issues (e.g., human capital, health and safety, changing customer behavior) or governance issues (e.g., board composition, executive compensation, shareholder dilution).

The following are principal risks associated with investing in the fund.

*Market conditions* — The prices of, and the income generated by, the securities held by the fund may decline – sometimes rapidly or unpredictably – due to various factors, including events or conditions affecting the general economy or particular industries or companies; overall market changes; local, regional or global political, social or economic instability; governmental, governmental agency or central bank responses to economic conditions; levels of public debt and deficits; changes in inflation rates; and currency exchange rate, interest rate and commodity price fluctuations.

Economies and financial markets throughout the world are highly interconnected. Economic, financial or political events, trading and tariff arrangements, wars, terrorism, cybersecurity events, natural disasters, public health emergencies (such as the spread of infectious disease), bank failures and other circumstances in one country or region, including actions taken by governmental or quasi-governmental authorities in response to any of the foregoing, could have impacts on global economies or markets. As a result, whether or not the fund invests in securities of issuers located in or with significant exposure to the countries affected, the value and liquidity of the fund's investments may be negatively affected by developments in other countries and regions.

*Issuer risks* — The prices of, and the income generated by, securities held by the fund may decline in response to various factors directly related to the issuers of such securities, including reduced demand for an issuer's goods or services, poor management performance, major litigation, investigations or other controversies related to the issuer, changes in the issuer's financial condition or credit rating, changes in government regulations affecting the issuer or its competitive environment and strategic initiatives such as mergers, acquisitions or dispositions and the market response to any such initiatives. An individual security may also be affected by factors relating to the industry or sector of the issuer or the securities markets as a whole, and conversely an industry or sector or the securities markets

American Funds Insurance Series / Prospectus&nbsp;&nbsp;&nbsp;&nbsp; 8

may be affected by a change in financial condition or other event affecting a single issuer. To the extent that the market prices of securities of issuers in the same or related industries or sectors tend to move in the same direction at the same time, and these issuers make up a sizeable portion of the market, events affecting one issuer, industry or sector or the securities markets generally may have a larger impact. If such issuers represent a substantial portion of major market indices, or the economy, a downturn in the prices of their securities may have a disproportionate adverse effect on the overall market, even if other segments of the market perform well. The fund's portfolio managers invest in issuers based on their level of investment conviction. At times, the fund may invest more significantly in a single issuer, which could increase the fund's volatility and the risk of loss arising from the factors described above.

*Investing in growth-oriented stocks* — Growth-oriented common stocks and other equity-type securities (such as preferred stocks, convertible preferred stocks and convertible bonds) may involve larger price swings and greater potential for loss than other types of investments. These risks may be even greater in the case of smaller capitalization stocks.

*Investing in small companies* — Investing in smaller companies may pose additional risks. For example, it is often more difficult to value or dispose of small company stocks and more difficult to obtain information about smaller companies than about larger companies. Furthermore, smaller companies often have limited product lines, operating histories, markets and/or financial resources, may be dependent on one or a few key persons for management, and can be more susceptible to losses. Moreover, the prices of their stocks may be more volatile than stocks of larger, more established companies, particularly during times of market turmoil.

*Investing outside the United States* — Securities of issuers domiciled outside the United States or with significant operations or revenues outside the United States, and securities tied economically to countries outside the United States, may lose value because of adverse political, social, economic or market developments (including social instability, regional conflicts, terrorism and war) in the countries or regions in which the issuers are domiciled, operate or generate revenue or to which the securities are tied economically. These securities may also lose value due to changes in foreign currency exchange rates against the U.S. dollar and/or currencies of other countries. Issuers of these securities may be more susceptible to actions of foreign governments, such as nationalization, currency blockage or the imposition of price controls, sanctions, or punitive taxes, each of which could adversely impact the value of these securities. Securities markets in certain countries may be more volatile and/or less liquid than those in the United States. Investments outside the United States may also be subject to different regulatory, legal, accounting, auditing, financial reporting and recordkeeping requirements, and may be more difficult to value, than those in the United States. In addition, the value of investments outside the United States may be reduced by foreign taxes, including foreign withholding taxes on interest and dividends. Further, there may be increased risks of delayed settlement of securities purchased or sold by the fund, which could impact the liquidity of the fund's portfolio. The risks of investing outside the United States may be heightened in connection with investments in emerging markets.

*Investing in emerging markets* — Investing in emerging markets may involve risks in addition to and greater than those generally associated with investing in the securities markets of developed countries. For instance, emerging market countries tend to have less developed political, economic and legal systems than those in developed countries. Accordingly, the governments of these countries may be less stable and more likely to intervene in the market economy, for example, by imposing capital controls, nationalizing a company or industry, placing restrictions on foreign ownership and on withdrawing sale proceeds of securities from the country, and/or imposing punitive taxes that could adversely affect the prices of securities. Information regarding issuers in emerging markets may be limited, incomplete or inaccurate, and such issuers may not be subject to regulatory, accounting, auditing, and financial reporting and recordkeeping standards comparable to those to which issuers in more developed markets are subject. The fund's rights with respect to its investments in emerging markets, if any, will generally be governed by local law, which may make it difficult or impossible for the fund to pursue legal remedies or to obtain and enforce judgments in local courts. In addition, the economies of these countries may be dependent on relatively few industries, may have limited access to capital and may be more susceptible to changes in local and global trade conditions and downturns in the world economy. Securities markets in these countries can also be relatively small and have substantially lower trading volumes. As a result, securities issued in these countries may be more volatile and less liquid, more vulnerable to market manipulation, and more difficult to value, than securities issued in countries with more developed economies and/or markets. Less certainty with respect to security valuations may lead to additional challenges and risks in calculating the fund's net asset value. Additionally, emerging markets are more likely to experience problems with the clearing and settling of trades and the holding of securities by banks, agents and depositories that are less established than those in developed countries.

*Liquidity risk* — Certain fund holdings may be or may become difficult or impossible to sell, particularly during times of market turmoil. Liquidity may be impacted by the lack of an active market for a holding, legal or contractual restrictions on resale, or the reduced number and capacity of market participants to make a market in such holding. Market prices for less liquid or illiquid holdings may be volatile or difficult to determine, and reduced liquidity may have an adverse impact on the market price of such holdings. Additionally, the sale of less liquid or illiquid holdings may involve substantial delays (including delays in settlement) and additional costs and the fund may be unable to sell such holdings when necessary to meet its liquidity needs or to try to limit losses, or may be forced to sell at a loss.

*Management* — The investment adviser to the fund actively manages the fund's investments. Consequently, the fund is subject to the risk that the methods and analyses, including models, tools and data, employed by the investment adviser in this process may be flawed or incorrect and may not produce the desired results. This could cause the fund to lose value or its investment results to lag relevant benchmarks or other funds with similar objectives.

The following are additional risks associated with investing in the fund.

*Exposure to country, region, industry or sector* — Subject to the fund's investment limitations, the fund may have significant exposure to a particular country, region, industry or sector. Such exposure may cause the fund to be more impacted by risks relating to and developments affecting the country, region, industry or sector, and thus its net asset value may be more volatile, than a fund without such

9&nbsp;&nbsp;&nbsp;&nbsp; American Funds Insurance Series / Prospectus

------

levels of exposure. For example, if the fund has significant exposure in a particular country, then social, economic, regulatory or other issues that negatively affect that country may have a greater impact on the fund than on a fund that is more geographically diversified.

*Lending of portfolio securities —* Securities lending involves risks, including the risk that the loaned securities may not be returned in a timely manner or at all, which would interfere with the fund's ability to vote proxies or settle transactions, and/or the risk of a counterparty default. Additionally, the fund may lose money from the reinvestment of collateral received on loaned securities in investments that decline in value, default or do not perform as expected.

*Cybersecurity breaches* — The fund may be subject to operational and information security risks through breaches in cybersecurity. Cybersecurity breaches can result from deliberate attacks or unintentional events, including "ransomware" attacks, the injection of computer viruses or malicious software code, the use of vulnerabilities in code to gain unauthorized access to digital information systems, networks or devices, or external attacks such as denial-of-service attacks on the investment adviser's or an affiliate's website that could render the fund's network services unavailable to intended end-users. These breaches may, among other things, lead to the unauthorized release of confidential information, misuse of the fund's assets or sensitive information, the disruption of the fund's operational capacity, the inability of fund shareholders to transact business, or the destruction of the fund's physical infrastructure, equipment or operating systems. These events could cause the fund to violate applicable privacy and other laws and could subject the fund to reputational damage, additional costs associated with corrective measures and/or financial loss. The fund may also be subject to additional risks if its third-party service providers, such as the fund's investment adviser, transfer agent, custodian, administrators and other financial intermediaries, experience similar cybersecurity breaches and potential outcomes. Cybersecurity risks may also impact issuers of securities in which the fund invests, which may cause the fund's investments in such issuers to lose value.

*Large shareholder transactions risk* — The fund may experience adverse effects when shareholders, including other funds or accounts advised by the investment adviser, purchase or redeem, individually or in the aggregate, large amounts of shares relative to the size of the fund. For example, when the investment adviser changes allocations in other funds and accounts it manages, such changes may result in shareholder transactions in the fund that are large relative to the size of the fund. Such large shareholder redemptions may cause the fund to sell portfolio securities at times when it would not otherwise do so, which may negatively impact the fund's net asset value and liquidity. Similarly, large fund share purchases may adversely affect the fund's performance to the extent that the fund is delayed in investing new cash and is required to maintain a larger cash position than it ordinarily would. These transactions may also accelerate the realization of taxable income to shareholders if such sales of investments resulted in gains, and may also increase transaction costs. In addition, a large redemption could result in the fund's current expenses being allocated over a smaller asset base, leading to an increase in the fund's expense ratio. These risks are heightened when the fund is small.

In addition to the principal investment strategies described above, the fund has other investment practices that are described in the statement of additional information, which includes a description of other risks related to the fund's principal investment strategies and other investment practices. The fund's investment results will depend on the ability of the fund's investment adviser to navigate the risks discussed above as well as those described in the statement of additional information.

**Fund comparative indexes** — The MSCI ACWI IMI Index is a free float-adjusted market capitalization-weighted index that is designed to measure the equity market results of large, mid, and small capitalization companies in both developed and emerging markets. The index consists of more than 40 developed and emerging market country indexes. Results reflect dividends net of withholding taxes. This index is unmanaged, and its results include reinvested dividends and/or distributions but do not reflect the effect of sales charges, commissions, account fees, expenses or U.S. federal income taxes.The MSCI All Country World Small Cap Index is a free float-adjusted market capitalization-weighted index that is designed to measure equity market results of smaller capitalization companies in both developed and emerging markets. Results reflect dividends net of withholding taxes. This index is unmanaged, and its results include reinvested dividends and/or distributions but do not reflect the effect of sales charges, commissions, account fees, expenses or U.S. federal income taxes.

**Portfolio holdings** A description of the fund's policies and procedures regarding disclosure of information about its portfolio holdings is available in the statement of additional information.

**EUPAC Fund** The fund's investment objective is to provide you with long-term growth of capital. While it has no present intention to do so, the fund's board may change the fund's investment objective without shareholder approval upon 60 days' written notice to shareholders.

The fund is designed for investors seeking capital appreciation and diversification through investments in common stocks and other equity-type securities (including depositary receipts), consistent with the fund's investment objective.

Investors in the fund should have a long-term perspective and be able to tolerate potentially sharp declines in value.

The following describes certain strategies that the investment adviser uses in pursuit of the fund's investment objective and the corresponding risks:

The fund invests primarily in common stocks in Europe and the Pacific Basin that the investment adviser believes have the potential for growth. Growth stocks are stocks that the investment adviser believes have the potential for above-average capital appreciation.

Normally, the fund will invest at least 80% of its net assets in securities of issuers in Europe and the Pacific Basin. This policy is subject to change only upon 60 days' notice to shareholders. A country will be considered part of Europe if it is part of the MSCI European indexes, and part of the Pacific Basin if any of its borders touches the Pacific Ocean. In determining the domicile of an issuer, the fund's investment adviser will generally look to the determination of MSCI Inc. (MSCI) for equity securities and Bloomberg for debt securities. In certain limited circumstances (including where relevant data is unavailable or the nature of a holding warrants special considerations), the adviser may also take into account additional factors, as applicable, including where the issuer's securities are listed; where the issuer is legally

organized, maintains principal corporate offices, conducts its principal operations, generates revenues and/or has credit risk exposure; and the source of guarantees, if any, of such securities. The fund may invest a portion of its assets in common stocks and other securities of companies in emerging markets.

The fund may also hold cash, cash equivalents and fixed-income securities, including commercial paper and short-term securities issued by the U.S. government, its agencies and instrumentalities. The percentage of the fund invested in such holdings varies and depends on various factors, including market conditions and purchases and redemptions of fund shares. The investment adviser may determine that it is appropriate to invest a substantial portion of the fund's assets in such instruments in response to certain circumstances, such as periods of market turmoil. For temporary defensive purposes, the fund may invest without limitation in such instruments. A larger percentage of such holdings could moderate the fund's investment results in a period of rising market prices. Alternatively, a larger percentage of such holdings could reduce the magnitude of the fund's loss in a period of falling market prices and provide liquidity to make additional investments or to meet redemptions.

The fund may invest in certain other funds managed by the investment adviser or its affiliates ("Central Funds") to more effectively invest in a diversified set of securities in a specific asset class such as money market instruments, bonds and other securities. Shares of Central Funds are only offered for purchase to the fund's investment adviser and its affiliates and other funds, investment vehicles and accounts managed by the fund's investment adviser and its affiliates. Central Funds do not charge management fees. As a result, the fund does not bear additional management fees when investing in Central Funds, but the fund does bear its proportionate share of Central Fund expenses. The investment results of the portions of the fund's assets invested in the Central Funds will be based upon the investment results of the Central Funds.

The fund may also lend portfolio securities to brokers, dealers and other institutions that provide cash or U.S. Treasury securities as collateral in an amount at least equal to the value of the securities loaned.

The following are principal risks associated with investing in the fund.

*Market conditions* — The prices of, and the income generated by, the common stocks and other securities held by the fund may decline – sometimes rapidly or unpredictably – due to various factors, including events or conditions affecting the general economy or particular industries or companies; overall market changes; local, regional or global political, social or economic instability; governmental, governmental agency or central bank responses to economic conditions; levels of public debt and deficits; changes in inflation rates; and currency exchange rate, interest rate and commodity price fluctuations.

*Investing outside the United States* — Securities of issuers domiciled outside the United States or with significant operations or revenues outside the United States, and securities tied economically to countries outside the United States, may lose value because of adverse

political, social, economic or market developments (including social instability, regional conflicts, terrorism and war) in the countries or regions in which the issuers are domiciled, operate or generate revenue or to which the securities are tied economically. These securities may also lose value due to changes in foreign currency exchange rates against the U.S. dollar and/or currencies of other countries. Issuers of these securities may be more susceptible to actions of foreign governments, such as nationalization, currency blockage or the imposition of price controls, sanctions, or punitive taxes, each of which could adversely impact the value of these securities. Securities markets in certain countries may be more volatile and/or less liquid than those in the United States. Investments outside the United States may also be subject to different regulatory, legal, accounting, auditing, financial reporting and recordkeeping requirements, and may be more difficult to value, than those in the United States. In addition, the value of investments outside the United States may be reduced by foreign taxes, including foreign withholding taxes on interest and dividends. Further, there may be increased risks of delayed settlement of securities purchased or sold by the fund, which could impact the liquidity of the fund's portfolio. The risks of investing outside the United States may be heightened in connection with investments in emerging markets.

*Investing in emerging markets* — Investing in emerging markets may involve risks in addition to and greater than those generally associated with investing in the securities markets of developed countries. For instance, emerging market countries tend to have less developed political, economic and legal systems than those in developed countries. Accordingly, the governments of these countries may be less stable and more likely to intervene in the market economy, for example, by imposing capital controls, nationalizing a company or industry, placing restrictions on foreign ownership and on withdrawing sale proceeds of securities from the country, and/or imposing punitive taxes that could adversely affect the prices of securities. Information regarding issuers in emerging markets may be limited, incomplete or inaccurate, and such issuers may not be subject to regulatory, accounting, auditing, and financial reporting and recordkeeping standards comparable to those to which issuers in more developed markets are subject. The fund's rights with respect to its investments in emerging markets, if any, will generally be governed by local law, which may make it difficult or impossible for the fund to pursue legal remedies or to obtain and enforce judgments in local courts. In addition, the economies of these countries may be dependent on relatively few industries, may have limited access to capital and may be more susceptible to changes in local and global trade conditions and downturns in the world economy. Securities markets in these countries can also be relatively small and have substantially lower trading volumes. As a result, securities issued in these countries may be more volatile and less liquid, more vulnerable to market manipulation, and more difficult to value, than securities issued in countries with more developed economies and/or markets. Less certainty with respect to security valuations may lead to additional challenges and risks in calculating the fund's net asset value. Additionally, emerging markets are more likely to experience problems with the clearing and settling of trades and the holding of securities by banks, agents and depositories that are less established than those in developed countries.

*Management* — The investment adviser to the fund actively manages the fund's investments. Consequently, the fund is subject to the risk that the methods and analyses, including models, tools and data, employed by the investment adviser in this process may be flawed or incorrect and may not produce the desired results. This could cause the fund to lose value or its investment results to lag relevant benchmarks or other funds with similar objectives.

The following are additional risks associated with investing in the fund.

*Exposure to country, region, industry or sector* — Subject to the fund's investment limitations, the fund may have significant exposure to a particular country, region, industry or sector. Such exposure may cause the fund to be more impacted by risks relating to and developments affecting the country, region, industry or sector, and thus its net asset value may be more volatile, than a fund without such levels of exposure. For example, if the fund has significant exposure in a particular country, then social, economic, regulatory or other issues that negatively affect that country may have a greater impact on the fund than on a fund that is more geographically diversified.

*Investing in depositary receipts* — Depositary receipts are securities that evidence ownership interests in, and represent the right to receive, a security or a pool of securities that have been deposited with a bank or trust depository. Such securities may be less liquid or may trade at a lower price than the underlying securities of the issuer. Additionally, receipt of corporate information about the underlying issuer and proxy disclosure may not be timely and there may not be a correlation between such information and the market value of the depositary receipts.

*Liquidity risk* — Certain fund holdings may be or may become difficult or impossible to sell, particularly during times of market turmoil. Liquidity may be impacted by the lack of an active market for a holding, legal or contractual restrictions on resale, or the reduced number and capacity of market participants to make a market in such holding. Market prices for less liquid or illiquid holdings may be volatile or difficult to determine, and reduced liquidity may have an adverse impact on the market price of such holdings. Additionally, the sale of less liquid or illiquid holdings may involve substantial delays (including delays in settlement) and additional costs and the fund may be unable to sell such holdings when necessary to meet its liquidity needs or to try to limit losses, or may be forced to sell at a loss.

*Lending of portfolio securities —* Securities lending involves risks, including the risk that the loaned securities may not be returned in a timely manner or at all, which would interfere with the fund's ability to vote proxies or settle transactions, and/or the risk of a counterparty default. Additionally, the fund may lose money from the reinvestment of collateral received on loaned securities in investments that decline in value, default or do not perform as expected.

*Cybersecurity breaches* — The fund may be subject to operational and information security risks through breaches in cybersecurity. Cybersecurity breaches can result from deliberate attacks or unintentional events, including "ransomware" attacks, the injection of computer viruses or malicious software code, the use of vulnerabilities in code to gain unauthorized access to digital information systems, networks or devices, or external attacks such as denial-of-service attacks on the investment adviser's or an affiliate's website that could render the fund's network services unavailable to intended end-users. These breaches may, among other things, lead to the unauthorized release of confidential information, misuse of the fund's assets or sensitive information, the disruption of the fund's operational capacity, the inability of fund shareholders to transact business, or the destruction of the fund's physical infrastructure, equipment or operating

American Funds Insurance Series / Prospectus&nbsp;&nbsp;&nbsp;&nbsp; 12

------

systems. These events could cause the fund to violate applicable privacy and other laws and could subject the fund to reputational damage, additional costs associated with corrective measures and/or financial loss. The fund may also be subject to additional risks if its third-party service providers, such as the fund's investment adviser, transfer agent, custodian, administrators and other financial intermediaries, experience similar cybersecurity breaches and potential outcomes. Cybersecurity risks may also impact issuers of securities in which the fund invests, which may cause the fund's investments in such issuers to lose value.

*Large shareholder transactions risk* — The fund may experience adverse effects when shareholders, including other funds or accounts advised by the investment adviser, purchase or redeem, individually or in the aggregate, large amounts of shares relative to the size of the fund. For example, when the investment adviser changes allocations in other funds and accounts it manages, such changes may result in shareholder transactions in the fund that are large relative to the size of the fund. Such large shareholder redemptions may cause the fund to sell portfolio securities at times when it would not otherwise do so, which may negatively impact the fund's net asset value and liquidity. Similarly, large fund share purchases may adversely affect the fund's performance to the extent that the fund is delayed in investing new cash and is required to maintain a larger cash position than it ordinarily would. These transactions may also accelerate the realization of taxable income to shareholders if such sales of investments resulted in gains, and may also increase transaction costs. In addition, a large redemption could result in the fund's current expenses being allocated over a smaller asset base, leading to an increase in the fund's expense ratio. These risks are heightened when the fund is small.

In addition to the principal investment strategies described above, the fund has other investment practices that are described in the statement of additional information, which includes a description of other risks related to the fund's principal investment strategies and other investment practices. The fund's investment results will depend on the ability of the fund's investment adviser to navigate the risks discussed above as well as those described in the statement of additional information.

**Fund comparative indexes** — The MSCI All Country World ex USA Index is a free float-adjusted market capitalization-weighted index that is designed to measure equity market results in the global developed and emerging markets, excluding the United States. The index consists of more than 40 developed and emerging market country indexes. Results reflect dividends net of withholding taxes. This index is unmanaged, and its results include reinvested dividends and/or distributions but do not reflect the effect of sales charges, commissions, account fees, expenses or U.S. federal income taxes.

**Management and organization**

**Investment adviser** Capital Research and Management Company, an experienced investment management organization founded in 1931, serves as the investment adviser to the Series and other funds, including the American Funds. Capital Research and Management Company is a wholly owned subsidiary of The Capital Group Companies, Inc. and is located at 333 South Hope Street, Los Angeles, California 90071. Capital Research and Management Company manages the investment portfolios and business affairs of the Series. The total management fee paid by each fund to its investment adviser for the most recent fiscal year, including any amounts waived, in each case expressed as a percentage of average net assets of that fund, appears in the Annual Fund Operating Expenses table for each fund. Please see the statement of additional information for further details. A discussion regarding the basis for the approval of the Series' Investment Advisory and Service Agreement by the Series' board of trustees is contained in the Series' annual or semi-annual report in Form N-CSR for the most recent fiscal period.

Capital Research and Management Company manages equity assets through three equity investment divisions and fixed income assets through its fixed income investment division, Capital Fixed Income Investors. The three equity investment divisions — Capital International Investors, Capital Research Global Investors and Capital World Investors — make investment decisions independently of one another.

The equity investment divisions may, in the future, be incorporated as wholly owned subsidiaries of Capital Research and Management Company. In that event, Capital Research and Management Company would continue to be the investment adviser, and day-to-day investment management of equity assets would continue to be carried out through one or more of these subsidiaries. Although not currently contemplated, Capital Research and Management Company could incorporate its fixed income investment division in the future and engage it to provide day-to-day investment management of fixed income assets. Capital Research and Management Company and each of the funds it advises have received an exemptive order from the U.S. Securities and Exchange Commission that allows Capital Research and Management Company to use, upon approval of the funds' boards, its management subsidiaries and affiliates to provide day-to-day investment management services to the funds, including making changes to the management subsidiaries and affiliates providing such services. The Series' shareholders approved this arrangement; however, there is no assurance that Capital Research and Management Company will incorporate its investment divisions or exercise any authority granted to it under the exemptive order.

In addition, shareholders of the Series have approved a proposal to reorganize the Series into a Delaware statutory trust. However, the Series reserved the right to delay implementing the reorganization and has elected to do so.

**The Capital System<sup>TM</sup>** Capital Research and Management Company uses a system of multiple portfolio managers in managing fund assets. Under this approach, the portfolio of a fund is divided into segments managed by individual managers. In addition, Capital Research and Management Company's investment analysts may make investment decisions with respect to a portion of each underlying fund's portfolio. Investment decisions are subject to a fund's objective(s), policies and restrictions and the oversight of the appropriate investment-related committees of Capital Research and Management Company and its investment divisions.

Certain senior members of Capital Fixed Income Investors, the investment adviser's fixed income investment division, serve on the Portfolio Strategy Group. The group utilizes a research-driven process with input from the investment adviser's analysts, portfolio managers and economists to define investment themes on a range of macroeconomic factors, including duration, yield curve and sector allocation. Where applicable, the investment decisions made by a fund's fixed income portfolio managers are informed by the investment themes discussed by the group.

Information regarding the portfolio managers' compensation, their ownership of securities in the Series and other accounts they manage is in the statement of additional information.

**Purchases and redemptions of shares** Shares of the Series are currently offered only to insurance company separate accounts as well as so-called "feeder funds" under master-feeder arrangements sponsored by insurance companies as underlying investments for such insurance companies' variable annuity contracts and variable life insurance policies. All such shares may be purchased or redeemed by the insurance company separate accounts (or feeder funds) at net asset value without any sales or redemption charges. These purchases and redemptions are made at the price next determined after such purchases and redemptions of units of the separate accounts (or feeder funds). The Series typically expects to remit redemption proceeds one business day following receipt and acceptance of a redemption order, regardless of the method the Series uses to make such payment (e.g., check, wire or automated clearing house transfer). However, payment may take longer than one business day and may take up to seven days as generally permitted by the Investment Company Act of 1940, as amended (the "1940 Act"). Under the 1940 Act, the Series may be permitted to pay redemption proceeds beyond seven days under certain limited circumstances.

Under normal conditions, the Series typically expects to meet shareholder redemptions from a reserve of highly liquid assets, such as cash or cash equivalents. The Series may use additional methods to meet shareholder redemptions, if they become necessary. These methods may include, but are not limited to, the sale of portfolio assets, the use of overdraft protection afforded by the Series' custodian bank, borrowing from a line of credit and making payment with fund securities or other fund assets rather than in cash (as further discussed in the following paragraph).

Although payment of redemptions normally will be in cash, the Series may pay the redemption price wholly or partly with portfolio securities or other fund assets under conditions and circumstances determined by the Series' board of trustees. On the same redemption date, some shareholders may be paid in whole or in part in securities (which may differ among those shareholders), while other shareholders may be paid entirely in cash. In general, in-kind redemptions to affiliated shareholders will as closely as practicable represent the affiliated shareholder's pro rata share of the Series' securities, subject to certain exceptions. Securities distributed in-kind to unaffiliated shareholders will be selected by the investment adviser in a manner the investment adviser deems to be fair and reasonable to the Series' shareholders. The disposal of the securities received in-kind may be subject to brokerage costs and, until sold, such securities remain subject to market risk and liquidity risk, including the risk that such securities are or become difficult to sell. If the Series pays your redemption with illiquid or less liquid securities, you will bear the risk of not being able to sell such securities.

**Frequent trading of fund shares** The Series and Capital Client Group, Inc., the Series' distributor, reserve the right to reject any purchase order for any reason. The funds are not designed to serve as vehicles for frequent trading. Frequent trading of fund shares may lead to increased costs to the funds and less efficient management of the funds' portfolios, potentially resulting in dilution of the value of the shares held by long-term shareholders. Accordingly, purchases, including those that are part of exchange activity, that the Series or Capital Client Group, Inc. has determined could involve actual or potential harm to a fund may be rejected.

The Series, through its transfer agent, American Funds Service Company, has agreements with the Series' insurance relationships to maintain its surveillance procedures that are designed to detect frequent trading in fund shares. The agreements generally require the insurance companies to (i) provide, upon request from a fund, the Series or their agent, certain identifying and account information regarding contract owners who invest in fund shares through an insurance company account and (ii) execute instructions from a fund, the Series or their agent to restrict further purchases or exchanges of fund shares by a contract owner who the Series has identified as having engaged in potentially harmful market timing or frequent trading. Under these procedures, various analytics are used to evaluate factors that may be indicative of frequent trading. For example, transactions in fund shares that exceed certain monetary thresholds may be scrutinized. American Funds Service Company may work with the insurance company separate accounts or feeder funds to apply their procedures that American Funds Service Company believes are reasonably designed to enforce the frequent trading policies of the Series. You should refer to disclosures provided by the insurance company with which you have a contract to determine the specific trading restrictions that apply to you.

Under the Series' frequent trading policy, certain trading activity will not be treated as frequent trading, such as:

· retirement plan contributions, loans and distributions (including hardship withdrawals) identified as such on the retirement plan recordkeeper's system;

· purchases and redemptions in community foundation accounts;

· purchase transactions involving in-kind transfers of fund shares, if the entity maintaining the contract owner's account is able to identify the transaction as one of these types of transactions;

· transactions by certain intermediaries in accordance with established hedging programs approved by the fund's investment adviser; and

· systematic redemptions and purchases if the entity maintaining the contract owner's account is able to identify the transaction as a systematic redemption or purchase.

Generally, purchases and redemptions will not be considered "systematic" unless the transaction is prescheduled for a specific date.

American Funds Service Company will monitor for other types of activity that could potentially be harmful to the Series – for example short-term trading activity in multiple funds. If American Funds Service Company identifies any activity that may constitute frequent trading, it reserves the right to contact the insurance company separate account or feeder fund and request that the separate account or feeder fund either provide information regarding an account owner's transactions or restrict the account owner's trading. If American Funds Service Company is not satisfied that insurance company separate account or feeder fund has taken appropriate action, American Funds Service Company may terminate the separate account's or feeder fund's ability to transact in fund shares.

There is no guarantee that all instances of frequent trading in fund shares will be prevented.

**Notwithstanding the Series' surveillance procedures described above, all transactions in fund shares remain subject to the right of the Series, Capital Client Group, Inc. and American Funds Service Company to restrict potentially abusive trading generally, including the types of transactions described above that will not be prevented.**

**Valuing shares** The net asset value of each share class of a fund is the value of a single share of that class. Net asset value is computed by adding a class's share of the value of a fund's investments, cash and other assets, subtracting the class's share of the fund's liabilities allocated to the class, and dividing the result by the number of shares of that class that are outstanding. Realized investment income and gain is included in the fund's net asset value until the ex-dividend date, when the declared dividend amount is treated as a fund liability. The net asset value per share is calculated once daily as of the close of regular trading on the New York Stock Exchange, normally 4 p.m. New York time, each day the New York Stock Exchange is open. If the New York Stock Exchange makes a scheduled (e.g., the day after Thanksgiving) or an unscheduled close prior to 4 p.m. New York time, the net asset value of each fund will be determined at approximately the time the New York Stock Exchange closes on that day. If on such a day market quotations and prices from third-party pricing services are not based as of the time of the early close of the New York Stock Exchange but are as of a later time (up to approximately 4 p.m. New York time), for example because the market remains open after the close of the New York Stock Exchange, those later market quotations and prices will be used in determining the funds' net asset value.

Equity securities are valued primarily on the basis of market quotations, and debt securities are valued primarily on the basis of prices from third-party pricing services due to the lack of market quotations. Futures contracts are valued primarily on the basis of settlement prices. The funds' portfolio investments are valued in accordance with procedures for making fair value determinations if market quotations are not readily available, including procedures to determine the representativeness of third-party vendor prices, or in the event market quotations or third-party vendor prices are not considered reliable. For example, if events occur between the close of markets outside the United States and the close of regular trading on the New York Stock Exchange that, in the opinion of the investment adviser, materially affect the value of any of the funds' equity securities that trade principally in those international markets, those securities will be valued in accordance with fair value procedures. Similarly, fair value procedures will be employed if an issuer defaults on its debt securities and there is no market for its securities. Use of these procedures is intended to result in more appropriate net asset values and, where applicable, to reduce potential arbitrage opportunities otherwise available to short-term investors.

Because certain of the funds may hold securities that are listed primarily on foreign exchanges that trade on weekends or days when the funds do not price their shares, the values of securities held in the funds may change on days when you will not be able to purchase or redeem fund shares.

Shares of the funds will be purchased or sold at the net asset value next determined after receipt of requests from the appropriate insurance company. Requests received by the appropriate insurance company prior to 4 p.m. New York time and communicated by the insurance company to the Series or its agent will be purchased or sold at that day's net asset value. Orders in good order received after the New York Stock Exchange closes (scheduled or unscheduled) will be processed at the net asset value (plus any applicable sales charge) calculated on the following business day.

**Plan of distribution** The Series has not adopted (and does not presently intend to adopt) a plan of distribution or "12b-1 plan" for Class 1 shares.

**Other compensation to dealers** Capital Client Group, Inc., at its expense, provides additional compensation to insurance companies. These payments may be made, at the discretion of Capital Client Group, Inc., to insurance companies (or their affiliates) that have sold shares of the funds of the American Funds Insurance Series and American Funds as the exclusive underlying investments to their variable annuity contracts. A number of factors will be considered in determining payments, including the sales, assets, and the quality of the insurance company's relationship with Capital Client Group, Inc. The payment will typically be determined using a formula applied consistently to insurance companies based on the relevant facts and circumstances. Aggregate payments made by Capital Client Group, Inc. to insurance companies may also change from year to year. Only assets and deposits in variable annuity contracts that offer exclusively shares of the funds of the American Funds Insurance Series and American Funds are included in the formula. Further, assets for which the insurance company, or an affiliated broker-dealer, acts as an ERISA investment fiduciary are generally excluded from the formula. Capital Client Group, Inc. makes these payments to help defray the costs incurred by qualifying insurance companies in connection with efforts to educate their sales force about the American Funds Insurance Series and American Funds so that they help financial advisers make recommendations and provide services that are suitable and meet contractholders' needs. These payments may also be made to help defray the costs associated with the insurance company's provision of account-related services and activities and support the insurance company's distribution activities. Capital Client Group, Inc. will, on a periodic basis, determine the advisability of continuing these payments. As of May 1, 2026, the insurance companies (or their affiliates) that Capital Client Group, Inc. anticipates will receive additional compensation based on prior payments include Lincoln National Life Insurance Co.

Firms receiving additional compensation payments must sign a letter acknowledging the purpose of the payment and Capital Client Group, Inc.'s goal that the payment will help facilitate education of their sales force about the American Funds Insurance Series and American Funds to help financial professionals make suitable recommendations and better serve their clients who invest in the funds as underlying investments to variable annuity contracts. The letters generally require the firms to (1) offers shares of the funds of the American Funds Insurance Series and American Funds as the exclusive underlying investments to their variable annuity contracts, and (2) provide Capital Client Group, Inc. broad access to their sales force and product platforms and develop a business plan to achieve such access.

Capital Client Group, Inc. may also pay expenses associated with meetings and other training and educational opportunities conducted by insurance companies, selling dealers, advisory platform providers and other intermediaries to facilitate educating financial professionals and shareholders about the American Funds Insurance Series and American Funds. For example, some of these expenses may include, but not be limited to, meeting sponsor fees, meeting location fees, fees for data and reporting, and fees to obtain lists of financial professionals to better tailor training and education opportunities. In addition, Capital Client Group, Inc. and/or its affiliates may make payments to third parties for platform fees and other services.

If investment advisers, distributors or other affiliates of mutual funds pay additional compensation or other incentives to insurance companies in differing amounts, insurance companies and the financial professionals with which they interact may have financial incentives for recommending a particular mutual fund over other mutual funds or investments, creating a potential conflict of interest. You should consult with your financial professional and review carefully any disclosure by your financial professional's firm as to compensation received.

**Fund expenses** In periods of market volatility, assets of the funds may decline significantly, causing total annual fund operating expenses (as a percentage of the value of your investment) to become higher than the numbers shown in the Annual Fund Operating Expenses tables in this prospectus.

The "Other expenses" items in the Annual Fund Operating Expenses tables in this prospectus are based on expenses as of each fund's most recently completed fiscal year. These items include third-party expenses, such as custodial, legal, audit, accounting, regulatory reporting and pricing vendor services, and an administrative services fee payable to the Series' investment adviser for administrative services provided by the Series' investment adviser and its affiliates.

For all share classes, "Other expenses" items in the Annual Fund Operating Expenses table in this prospectus include fees for administrative services provided by the fund's investment adviser and its affiliates. Administrative services are provided by the investment adviser and its affiliates to help assist third parties providing non-distribution services to fund shareholders. These services include providing in-depth information on the fund and market developments that impact fund investments. Administrative services also include, but are not limited to, coordinating, monitoring and overseeing third parties that provide services to fund shareholders.

The Administrative Services Agreement between the fund and the investment adviser provides the fund the ability to charge an administrative services fee of .05% for all share classes. The fund's investment adviser receives an administrative services fee at the annual rate of .03% of the average daily net assets of the fund attributable to all share classes (which could be increased as noted above) for its provision of administrative services.

**Investment results** All fund results in the "Investment results" section of this prospectus reflect the reinvestment of dividends and capital gains distributions, if any. Unless otherwise noted, fund results reflect any fee waivers and/or expense reimbursements in effect during the period presented.

**Distributions and taxes** Each fund of the Series intends to qualify as a "regulated investment company" under the Internal Revenue Code. In any fiscal year in which a fund so qualifies and distributes to shareholders its investment company taxable income and net realized capital gain, the fund itself is relieved of federal income tax.

It is the Series' policy to distribute to the shareholders (the insurance company separate accounts) all of its investment company taxable income and capital gain for each fiscal year.

#### See the applicable contract prospectus for information regarding the federal income tax treatment of the contracts and distributions to the separate accounts.

**Financial highlights** The Financial Highlights table is intended to help you understand a fund's results for the past five fiscal years (or, if shorter, the period of operations). Certain information reflects financial results for a single share of a particular class. The total returns in the table represent the rate that an investor would have earned or lost on an investment in a fund (assuming reinvestment of all dividends and capital gain distributions). Where indicated, figures in the table reflect the impact, if any, of certain waivers from Capital Research and Management Company. For more information about these waivers, see the fund's statement of additional information and Form N-CSR. The information in the Financial Highlights table has been audited by PricewaterhouseCoopers LLP, whose current report, along with the funds' financial statements, is included in the statement of additional information, which is available upon request. Figures shown do not reflect insurance contract fees and expenses. If insurance contract fees and expenses were reflected, results would be lower.

**The U.S. Securities and Exchange Commission has not approved or disapproved of these securities. Further, it has not determined that this prospectus is accurate or complete. Any representation to the contrary is a criminal offense.**

 **SMALLCAP World Fund** 

**Investment objective** The fund's investment objective is to provide you with long-term growth of capital.

**Fees and expenses of the fund** This table describes the fees and expenses that you may pay if you buy, hold and sell an interest in Class 1A shares of the fund. **You may pay other fees, such as insurance contract fees and expenses, which are not reflected in the tables and examples below.** If insurance contract fees and expenses were reflected, expenses shown would be higher.

---

| | |
|:---|:---|
| **Annual fund operating expenses (expenses that you pay each year as a percentage of the net asset value of your investment)** | Class 1A |
| Management fee | 0.65% |
| Other expenses | 0.30 |
| Total annual fund operating expenses | 0.95 |
| Fee waiver\* | 0.05 |
| Total annual fund operating expenses after fee waiver | 0.90 |

---

\* The investment adviser is currently waiving a portion of its management fee equal to 0.05% of the fund's net assets. This waiver will be in effect through at least May 1, 2027. The waiver may only be modified or terminated with the approval of the fund's board.

**Example** This example is intended to help you compare the cost of investing in Class 1A shares of the fund with the cost of investing in other mutual funds.

The example assumes that you invest $10,000 in the fund for the time periods indicated and then redeem or hold all of your shares at the end of those periods. The example also assumes that your investment has a 5% return each year and that the fund's operating expenses remain the same. The example does not reflect insurance contract expenses. If insurance contract expenses were reflected, expenses shown would be higher. The example reflects the fee waiver described above through the expiration date of such waiver and total annual fund operating expenses thereafter. No sales charge (load) or other fees are charged by the fund upon redemption, so you would incur these hypothetical costs whether or not you were to redeem your shares at the end of the given period. Although your actual costs may be higher or lower, based on these assumptions your costs would be:

---

| | | | | |
|:---|:---|:---|:---|:---|
|  | 1 year | 3 years | 5 years | 10 years |
| Class 1A | $92 | $298 | $521 | $1162 |

---

**Portfolio turnover** The fund pays transaction costs, such as commissions, when it buys and sells securities (or "turns over" its portfolio). A higher portfolio turnover rate may indicate higher transaction costs. These costs, which are not reflected in annual fund operating expenses or in the example, affect the fund's investment results. During the most recent fiscal year, the fund's portfolio turnover rate was 51% of the average value of its portfolio.

**Principal investment strategies** Normally the fund invests at least 80% of its net assets in common stocks and other equity-type securities (such as preferred stocks, convertible preferred stocks and convertible bonds) of companies with small market capitalizations, including growth-oriented stocks. The investment adviser currently defines "small market capitalization" companies to be companies with market capitalizations within or below the capitalization range of companies included in the MSCI All Country World Small Cap Index or the Russell 2000 Index, measured based on the maximum market capitalization of companies in either index within the last 12 months. As of August 31, 2025, the largest company in the MSCI All Country World Small Cap Index had a market capitalization of approximately $25.9 billion and the largest company in the Russell 2000 Index had a market capitalization of approximately $20.9 billion. The market capitalization of the companies included in the MSCI All Country World Small Cap Index and the Russell 2000 Index will change with market conditions. The investment adviser has periodically re-evaluated and adjusted this definition and may continue to do so in the future. The fund may continue to hold securities of a portfolio company that subsequently appreciates above the small market capitalization threshold. Under normal circumstances, the fund will invest a significant portion of its assets outside the United States, including in emerging markets.

Prior to May 1, 2026, the fund was called Global Small Capitalization Fund.

The investment adviser uses a system of multiple portfolio managers in managing the fund's assets. Under this approach, the portfolio of the fund is divided into segments managed by individual managers.

The fund relies on the professional judgment of its investment adviser to make decisions about the fund's portfolio investments. The basic investment philosophy of the investment adviser is to seek to invest in attractively valued companies that, in its opinion, represent good, long-term investment opportunities. Securities may be sold when the investment adviser believes that they no longer represent relatively attractive investment opportunities.

**Principal risks This section describes the principal risks associated with investing in the fund. You may lose money by investing in the fund. The likelihood of loss may be greater if you invest for a shorter period of time.** 

*Market conditions* — The prices of, and the income generated by, the securities held by the fund may decline – sometimes rapidly or unpredictably – due to various factors, including events or conditions affecting the general economy or particular industries or companies; overall market changes; local, regional or global political, social or economic instability; governmental, governmental agency or central bank responses to economic conditions; levels of public debt and deficits; changes in inflation rates; and currency exchange rate, interest rate and commodity price fluctuations.

Economies and financial markets throughout the world are highly interconnected. Economic, financial or political events, trading and tariff arrangements, wars, terrorism, cybersecurity events, natural disasters, public health emergencies (such as the spread of infectious disease), bank failures and other circumstances in one country or region, including actions taken by governmental or quasi-governmental authorities in response to any of the foregoing, could have impacts on global economies or markets. As a result, whether or not the fund invests in securities of issuers located in or with significant exposure to the countries affected, the value and liquidity of the fund's investments may be negatively affected by developments in other countries and regions.

*Issuer risks* — The prices of, and the income generated by, securities held by the fund may decline in response to various factors directly related to the issuers of such securities, including reduced demand for an issuer's goods or services, poor management performance, major litigation, investigations or other controversies related to the issuer, changes in the issuer's financial condition or credit rating, changes in government regulations affecting the issuer or its competitive environment and strategic initiatives such as mergers, acquisitions or dispositions and the market response to any such initiatives. An individual security may also be affected by factors relating to the industry or sector of the issuer or the securities markets as a whole, and conversely an industry or sector or the securities markets may be affected by a change in financial condition or other event affecting a single issuer.

*Investing in growth-oriented stocks* — Growth-oriented common stocks and other equity-type securities (such as preferred stocks, convertible preferred stocks and convertible bonds) may involve larger price swings and greater potential for loss than other types of investments. These risks may be even greater in the case of smaller capitalization stocks.

*Investing in small companies* — Investing in smaller companies may pose additional risks. For example, it is often more difficult to value or dispose of small company stocks and more difficult to obtain information about smaller companies than about larger companies. Furthermore, smaller companies often have limited product lines, operating histories, markets and/or financial resources, may be dependent on one or a few key persons for management, and can be more susceptible to losses. Moreover, the prices of their stocks may be more volatile than stocks of larger, more established companies, particularly during times of market turmoil.

*Investing outside the United States* — Securities of issuers domiciled outside the United States or with significant operations or revenues outside the United States, and securities tied economically to countries outside the United States, may lose value because of adverse political, social, economic or market developments (including social instability, regional conflicts, terrorism and war) in the countries or regions in which the issuers are domiciled, operate or generate revenue or to which the securities are tied economically. These securities may also lose value due to changes in foreign currency exchange rates against the U.S. dollar and/or currencies of other countries. Issuers of these securities may be more susceptible to actions of foreign governments, such as nationalization, currency blockage or the imposition of price controls, sanctions, or punitive taxes, each of which could adversely impact the value of these securities. Securities markets in certain countries may be more volatile and/or less liquid than those in the United States. Investments outside the United States may also be subject to different regulatory, legal, accounting, auditing, financial reporting and recordkeeping requirements, and may be more difficult to value, than those in the United States. In addition, the value of investments outside the United States may be reduced by foreign taxes, including foreign withholding taxes on interest and dividends. Further, there may be increased risks of delayed settlement of securities purchased or sold by the fund, which could impact the liquidity of the fund's portfolio. The risks of investing outside the United States may be heightened in connection with investments in emerging markets.

------

*Investing in emerging markets* — Investing in emerging markets may involve risks in addition to and greater than those generally associated with investing in the securities markets of developed countries. For instance, emerging market countries tend to have less developed political, economic and legal systems than those in developed countries. Accordingly, the governments of these countries may be less stable and more likely to intervene in the market economy, for example, by imposing capital controls, nationalizing a company or industry, placing restrictions on foreign ownership and on withdrawing sale proceeds of securities from the country, and/or imposing punitive taxes that could adversely affect the prices of securities. Information regarding issuers in emerging markets may be limited, incomplete or inaccurate, and such issuers may not be subject to regulatory, accounting, auditing, and financial reporting and recordkeeping standards comparable to those to which issuers in more developed markets are subject. The fund's rights with respect to its investments in emerging markets, if any, will generally be governed by local law, which may make it difficult or impossible for the fund to pursue legal remedies or to obtain and enforce judgments in local courts. In addition, the economies of these countries may be dependent on relatively few industries, may have limited access to capital and may be more susceptible to changes in local and global trade conditions and downturns in the world economy. Securities markets in these countries can also be relatively small and have substantially lower trading volumes. As a result, securities issued in these countries may be more volatile and less liquid, more vulnerable to market manipulation, and more difficult to value, than securities issued in countries with more developed economies and/or markets. Less certainty with respect to security valuations may lead to additional challenges and risks in calculating the fund's net asset value. Additionally, emerging markets are more likely to experience problems with the clearing and settling of trades and the holding of securities by banks, agents and depositories that are less established than those in developed countries.

*Liquidity risk* — Certain fund holdings may be or may become difficult or impossible to sell, particularly during times of market turmoil. Liquidity may be impacted by the lack of an active market for a holding, legal or contractual restrictions on resale, or the reduced number and capacity of market participants to make a market in such holding. Market prices for less liquid or illiquid holdings may be volatile or difficult to determine, and reduced liquidity may have an adverse impact on the market price of such holdings. Additionally, the sale of less liquid or illiquid holdings may involve substantial delays (including delays in settlement) and additional costs and the fund may be unable to sell such holdings when necessary to meet its liquidity needs or to try to limit losses, or may be forced to sell at a loss.

*Management* — The investment adviser to the fund actively manages the fund's investments. Consequently, the fund is subject to the risk that the methods and analyses, including models, tools and data, employed by the investment adviser in this process may be flawed or incorrect and may not produce the desired results. This could cause the fund to lose value or its investment results to lag relevant benchmarks or other funds with similar objectives.

Your investment in the fund is not a bank deposit and is not insured or guaranteed by the Federal Deposit Insurance Corporation or any other governmental agency, entity or person. You should consider how this fund fits into your overall investment program.

**Investment results** The following bar chart shows how the investment results of the Class 1A shares of the fund have varied from year to year, and the following table shows how the fund's average annual total returns for various periods compare with a broad measure of securities market results and, if applicable, other measures of market results that reflect the fund's investment universe. This information provides some indication of the risks of investing in the fund. Past investment results (before and after taxes) are not predictive of future investment results. Figures shown reflect fees and expenses associated with an investment in the fund, but do not reflect insurance contract fees and expenses. If insurance contract fees and expenses were included, results would have been lower. Updated information on the fund's investment results can be obtained by visiting capitalgroup.com/afis.

\*Lifetime returns are from April 30, 1998, the date the fund began investment operations. Class 1A shares began investment operations on January 6, 2017; therefore, returns for the fund prior to that date assume a hypothetical investment in Class 1 shares, but reflect the .25% annual expense that applies to Class 1A shares and is described in the "Fund expenses" section of the prospectus. Returns for Class 1 shares are comparable to those of Class 1A shares because both classes invest in the same portfolio of securities.

**Purchase and sale of fund shares** Shares of the fund are not sold directly to the general public. The fund is offered only as an underlying investment option for variable insurance contracts, and insurance company separate accounts and qualified feeder funds — and not the holders of variable insurance contracts — are the shareholders of the fund. Although the fund does not require a minimum amount for initial or subsequent purchases from insurance companies, your insurance company may impose investment minimums for your purchase of the fund.

You may sell (redeem) shares on any business day. You must sell (redeem) shares through your insurance company.

**Tax information** See your variable insurance contract prospectus for information regarding the federal income tax treatment of your variable insurance contract and related distributions.

**Payments to broker-dealers and other financial intermediaries** The fund is not sold directly to the general public but instead is offered as an underlying investment option for variable insurance contracts. The fund and its related companies may make payments to the sponsoring insurance company (or its affiliates) for distribution and/or other services. These payments may be a factor that the insurance company considers in including the fund as an underlying investment option in the variable insurance contract. The prospectus (or other offering document) for your variable insurance contract may contain additional information about these payments.

**Investment objective** The fund's investment objective is to provide you with long-term growth of capital.

**Fees and expenses of the fund** This table describes the fees and expenses that you may pay if you buy, hold and sell an interest in Class 1A shares of the fund. **You may pay other fees, such as insurance contract fees and expenses, which are not reflected in the tables and examples below.** If insurance contract fees and expenses were reflected, expenses shown would be higher.

---

| | |
|:---|:---|
| **Annual fund operating expenses (expenses that you pay each year as a percentage of the net asset value of your investment)** | Class 1A |
| Management fee | 0.48% |
| Other expenses | 0.30 |
| Total annual fund operating expenses | 0.78 |
| Fee waiver\* | 0.06 |
| Total annual fund operating expenses after fee waiver | 0.72 |

---

\* The investment adviser is currently waiving a portion of its management fee equal to 0.06% of the fund's net assets. This waiver will be in effect through at least May 1, 2027. The waiver may only be modified or terminated with the approval of the fund's board.

**Example** This example is intended to help you compare the cost of investing in Class 1A shares of the fund with the cost of investing in other mutual funds.

The example assumes that you invest $10,000 in the fund for the time periods indicated and then redeem or hold all of your shares at the end of those periods. The example also assumes that your investment has a 5% return each year and that the fund's operating expenses remain the same. The example does not reflect insurance contract expenses. If insurance contract expenses were reflected, expenses shown would be higher. The example reflects the fee waiver described above through the expiration date of such waiver and total annual fund operating expenses thereafter. No sales charge (load) or other fees are charged by the fund upon redemption, so you would incur these hypothetical costs whether or not you were to redeem your shares at the end of the given period. Although your actual costs may be higher or lower, based on these assumptions your costs would be:

---

| | | | | |
|:---|:---|:---|:---|:---|
|  | 1 year | 3 years | 5 years | 10 years |
| Class 1A | $74 | $243 | $427 | $960 |

---

**Portfolio turnover** The fund pays transaction costs, such as commissions, when it buys and sells securities (or "turns over" its portfolio). A higher portfolio turnover rate may indicate higher transaction costs. These costs, which are not reflected in annual fund operating expenses or in the example, affect the fund's investment results. During the most recent fiscal year, the fund's portfolio turnover rate was 63% of the average value of its portfolio.

**Principal investment strategies** The fund invests primarily in common stocks in Europe and the Pacific Basin that the investment adviser believes have the potential for growth. Growth stocks are stocks that the investment adviser believes have the potential for above-average capital appreciation.

Normally the fund will invest at least 80% of its net assets in securities of issuers in Europe and the Pacific Basin. A country will be considered part of Europe if it is part of the MSCI European indexes, and part of the Pacific Basin if any of its borders touches the Pacific Ocean. In determining the domicile of an issuer, the fund's investment adviser will generally look to the determination of MSCI Inc. (MSCI) for equity securities and Bloomberg for debt securities. In certain limited circumstances (including where relevant data is unavailable or the nature of a holding warrants special considerations), the adviser may also take into account additional factors, as applicable, including where the issuer's securities are listed; where the issuer is legally organized, maintains principal corporate offices, conducts its principal operations, generates revenues and/or has credit risk exposure; and the source of guarantees, if any, of such securities. The fund may invest a portion of its assets in common stocks and other securities of companies in emerging markets.

Prior to May 1, 2026, the fund was called International Fund.

The investment adviser uses a system of multiple portfolio managers in managing the fund's assets. Under this approach, the portfolio of the fund is divided into segments managed by individual managers.

The fund relies on the professional judgment of its investment adviser to make decisions about the fund's portfolio investments. The basic investment philosophy of the investment adviser is to seek to invest in attractively valued companies that, in its opinion, represent good, long-term investment opportunities. Securities may be sold when the investment adviser believes that they no longer represent relatively attractive investment opportunities.

**Investment objectives, strategies and risks** 

**SMALLCAP World Fund** The fund's investment objective is to provide you with long-term growth of capital. While it has no present intention to do so, the fund's board may change the fund's investment objective without shareholder approval upon 60 days' prior written notice to shareholders. Normally the fund invests at least 80% of its net assets in common stocks and other equity-type securities (such as preferred stocks, convertible preferred stocks and convertible bonds) of companies with small market capitalizations, including growth-oriented stocks. This policy is subject to change only upon 60 days' prior written notice to shareholders. The investment adviser currently defines "small market capitalization" companies to be companies with market capitalizations within or below the capitalization range of companies included in the MSCI All Country World Small Cap Index or the Russell 2000 Index, measured based on the maximum market capitalization of companies in either index within the last 12 months. As of August 31, 2025, the largest company in the MSCI All Country World Small Cap Index had a market capitalization of approximately $25.9 billion and the largest company in the Russell 2000 Index had a market capitalization of approximately $20.9 billion. The market capitalization of the companies included in the MSCI All Country World Small Cap Index and the Russell 2000 Index will change with market conditions. The investment adviser has periodically re-evaluated and adjusted this definition and may continue to do so in the future. The fund may continue to hold securities of a portfolio company that subsequently appreciates above the small market capitalization threshold. Under normal circumstances, the fund will invest a significant portion of its assets outside the United States, including in emerging markets.

The fund may also hold cash or cash equivalents, including commercial paper and short-term securities issued by the U.S. government, its agencies and instrumentalities. The percentage of the fund invested in such holdings varies and depends on various factors, including market conditions and purchases and redemptions of fund shares. The investment adviser may determine that it is appropriate to invest a substantial portion of the fund's assets in such instruments in response to certain circumstances, such as periods of market turmoil. For temporary defensive purposes, the fund may invest without limitation in such instruments. A larger percentage of such holdings could moderate the fund's investment results in a period of rising market prices. Alternatively, a larger percentage of such holdings could reduce the magnitude of the fund's loss in a period of falling market prices and provide liquidity to make additional investments or to meet redemptions.

The fund may invest in certain other funds managed by the investment adviser or its affiliates ("Central Funds") to more effectively invest in a diversified set of securities in a specific asset class such as money market instruments, bonds and other securities. Shares of Central Funds are only offered for purchase to the fund's investment adviser and its affiliates and other funds, investment vehicles and accounts managed by the fund's investment adviser and its affiliates. Central Funds do not charge management fees. As a result, the fund does not bear additional management fees when investing in Central Funds, but the fund does bear its proportionate share of Central Fund expenses. The investment results of the portions of the fund's assets invested in the Central Funds will be based upon the investment results of the Central Funds.

The fund may also lend portfolio securities to brokers, dealers and other institutions that provide cash or U.S. Treasury securities as collateral in an amount at least equal to the value of the securities loaned.

Prior to May 1, 2026, the fund was called Global Small Capitalization Fund.

The fund relies on the professional judgment of its investment adviser to make decisions about the fund's portfolio investments. The basic investment philosophy of the investment adviser is to seek to invest in attractively valued companies that, in its opinion, represent good, long-term investment opportunities. The investment adviser believes that an important way to accomplish this is through fundamental analysis, which may include meeting with company executives and employees, suppliers, customers and competitors. Securities may be sold when the investment adviser believes that they no longer represent relatively attractive investment opportunities.

The investment adviser may consider environmental, social and governance ("ESG") factors that, depending on the facts and circumstances, are material to the value of an issuer or instrument. ESG factors may include, but are not limited to, environmental issues (e.g., water use, emission levels, waste, environmental remediation), social issues (e.g., human capital, health and safety, changing customer behavior) or governance issues (e.g., board composition, executive compensation, shareholder dilution).

The following are principal risks associated with investing in the fund.

*Market conditions* — The prices of, and the income generated by, the securities held by the fund may decline – sometimes rapidly or unpredictably – due to various factors, including events or conditions affecting the general economy or particular industries or companies; overall market changes; local, regional or global political, social or economic instability; governmental, governmental agency or central bank responses to economic conditions; levels of public debt and deficits; changes in inflation rates; and currency exchange rate, interest rate and commodity price fluctuations.

Economies and financial markets throughout the world are highly interconnected. Economic, financial or political events, trading and tariff arrangements, wars, terrorism, cybersecurity events, natural disasters, public health emergencies (such as the spread of infectious disease), bank failures and other circumstances in one country or region, including actions taken by governmental or quasi-governmental authorities in response to any of the foregoing, could have impacts on global economies or markets. As a result, whether or not the fund invests in securities of issuers located in or with significant exposure to the countries affected, the value and liquidity of the fund's investments may be negatively affected by developments in other countries and regions.

*Issuer risks* — The prices of, and the income generated by, securities held by the fund may decline in response to various factors directly related to the issuers of such securities, including reduced demand for an issuer's goods or services, poor management performance, major litigation, investigations or other controversies related to the issuer, changes in the issuer's financial condition or credit rating, changes in government regulations affecting the issuer or its competitive environment and strategic initiatives such as mergers, acquisitions or dispositions and the market response to any such initiatives. An individual security may also be affected by factors relating to the industry or sector of the issuer or the securities markets as a whole, and conversely an industry or sector or the securities markets

may be affected by a change in financial condition or other event affecting a single issuer. To the extent that the market prices of securities of issuers in the same or related industries or sectors tend to move in the same direction at the same time, and these issuers make up a sizeable portion of the market, events affecting one issuer, industry or sector or the securities markets generally may have a larger impact. If such issuers represent a substantial portion of major market indices, or the economy, a downturn in the prices of their securities may have a disproportionate adverse effect on the overall market, even if other segments of the market perform well. The fund's portfolio managers invest in issuers based on their level of investment conviction. At times, the fund may invest more significantly in a single issuer, which could increase the fund's volatility and the risk of loss arising from the factors described above.

*Investing in growth-oriented stocks* — Growth-oriented common stocks and other equity-type securities (such as preferred stocks, convertible preferred stocks and convertible bonds) may involve larger price swings and greater potential for loss than other types of investments. These risks may be even greater in the case of smaller capitalization stocks.

*Investing in small companies* — Investing in smaller companies may pose additional risks. For example, it is often more difficult to value or dispose of small company stocks and more difficult to obtain information about smaller companies than about larger companies. Furthermore, smaller companies often have limited product lines, operating histories, markets and/or financial resources, may be dependent on one or a few key persons for management, and can be more susceptible to losses. Moreover, the prices of their stocks may be more volatile than stocks of larger, more established companies, particularly during times of market turmoil.

*Investing outside the United States* — Securities of issuers domiciled outside the United States or with significant operations or revenues outside the United States, and securities tied economically to countries outside the United States, may lose value because of adverse political, social, economic or market developments (including social instability, regional conflicts, terrorism and war) in the countries or regions in which the issuers are domiciled, operate or generate revenue or to which the securities are tied economically. These securities may also lose value due to changes in foreign currency exchange rates against the U.S. dollar and/or currencies of other countries. Issuers of these securities may be more susceptible to actions of foreign governments, such as nationalization, currency blockage or the imposition of price controls, sanctions, or punitive taxes, each of which could adversely impact the value of these securities. Securities markets in certain countries may be more volatile and/or less liquid than those in the United States. Investments outside the United States may also be subject to different regulatory, legal, accounting, auditing, financial reporting and recordkeeping requirements, and may be more difficult to value, than those in the United States. In addition, the value of investments outside the United States may be reduced by foreign taxes, including foreign withholding taxes on interest and dividends. Further, there may be increased risks of delayed settlement of securities purchased or sold by the fund, which could impact the liquidity of the fund's portfolio. The risks of investing outside the United States may be heightened in connection with investments in emerging markets.

*Investing in emerging markets* — Investing in emerging markets may involve risks in addition to and greater than those generally associated with investing in the securities markets of developed countries. For instance, emerging market countries tend to have less developed political, economic and legal systems than those in developed countries. Accordingly, the governments of these countries may be less stable and more likely to intervene in the market economy, for example, by imposing capital controls, nationalizing a company or industry, placing restrictions on foreign ownership and on withdrawing sale proceeds of securities from the country, and/or imposing punitive taxes that could adversely affect the prices of securities. Information regarding issuers in emerging markets may be limited, incomplete or inaccurate, and such issuers may not be subject to regulatory, accounting, auditing, and financial reporting and recordkeeping standards comparable to those to which issuers in more developed markets are subject. The fund's rights with respect to its investments in emerging markets, if any, will generally be governed by local law, which may make it difficult or impossible for the fund to pursue legal remedies or to obtain and enforce judgments in local courts. In addition, the economies of these countries may be dependent on relatively few industries, may have limited access to capital and may be more susceptible to changes in local and global trade conditions and downturns in the world economy. Securities markets in these countries can also be relatively small and have substantially lower trading volumes. As a result, securities issued in these countries may be more volatile and less liquid, more vulnerable to market manipulation, and more difficult to value, than securities issued in countries with more developed economies and/or markets. Less certainty with respect to security valuations may lead to additional challenges and risks in calculating the fund's net asset value. Additionally, emerging markets are more likely to experience problems with the clearing and settling of trades and the holding of securities by banks, agents and depositories that are less established than those in developed countries.

*Liquidity risk* — Certain fund holdings may be or may become difficult or impossible to sell, particularly during times of market turmoil. Liquidity may be impacted by the lack of an active market for a holding, legal or contractual restrictions on resale, or the reduced number and capacity of market participants to make a market in such holding. Market prices for less liquid or illiquid holdings may be volatile or difficult to determine, and reduced liquidity may have an adverse impact on the market price of such holdings. Additionally, the sale of less liquid or illiquid holdings may involve substantial delays (including delays in settlement) and additional costs and the fund may be unable to sell such holdings when necessary to meet its liquidity needs or to try to limit losses, or may be forced to sell at a loss.

*Management* — The investment adviser to the fund actively manages the fund's investments. Consequently, the fund is subject to the risk that the methods and analyses, including models, tools and data, employed by the investment adviser in this process may be flawed or incorrect and may not produce the desired results. This could cause the fund to lose value or its investment results to lag relevant benchmarks or other funds with similar objectives.

The following are additional risks associated with investing in the fund.

*Exposure to country, region, industry or sector* — Subject to the fund's investment limitations, the fund may have significant exposure to a particular country, region, industry or sector. Such exposure may cause the fund to be more impacted by risks relating to and developments affecting the country, region, industry or sector, and thus its net asset value may be more volatile, than a fund without such

American Funds Insurance Series / Prospectus&nbsp;&nbsp;&nbsp;&nbsp; 10

------

levels of exposure. For example, if the fund has significant exposure in a particular country, then social, economic, regulatory or other issues that negatively affect that country may have a greater impact on the fund than on a fund that is more geographically diversified.

*Lending of portfolio securities —* Securities lending involves risks, including the risk that the loaned securities may not be returned in a timely manner or at all, which would interfere with the fund's ability to vote proxies or settle transactions, and/or the risk of a counterparty default. Additionally, the fund may lose money from the reinvestment of collateral received on loaned securities in investments that decline in value, default or do not perform as expected.

*Cybersecurity breaches* — The fund may be subject to operational and information security risks through breaches in cybersecurity. Cybersecurity breaches can result from deliberate attacks or unintentional events, including "ransomware" attacks, the injection of computer viruses or malicious software code, the use of vulnerabilities in code to gain unauthorized access to digital information systems, networks or devices, or external attacks such as denial-of-service attacks on the investment adviser's or an affiliate's website that could render the fund's network services unavailable to intended end-users. These breaches may, among other things, lead to the unauthorized release of confidential information, misuse of the fund's assets or sensitive information, the disruption of the fund's operational capacity, the inability of fund shareholders to transact business, or the destruction of the fund's physical infrastructure, equipment or operating systems. These events could cause the fund to violate applicable privacy and other laws and could subject the fund to reputational damage, additional costs associated with corrective measures and/or financial loss. The fund may also be subject to additional risks if its third-party service providers, such as the fund's investment adviser, transfer agent, custodian, administrators and other financial intermediaries, experience similar cybersecurity breaches and potential outcomes. Cybersecurity risks may also impact issuers of securities in which the fund invests, which may cause the fund's investments in such issuers to lose value.

*Large shareholder transactions risk* — The fund may experience adverse effects when shareholders, including other funds or accounts advised by the investment adviser, purchase or redeem, individually or in the aggregate, large amounts of shares relative to the size of the fund. For example, when the investment adviser changes allocations in other funds and accounts it manages, such changes may result in shareholder transactions in the fund that are large relative to the size of the fund. Such large shareholder redemptions may cause the fund to sell portfolio securities at times when it would not otherwise do so, which may negatively impact the fund's net asset value and liquidity. Similarly, large fund share purchases may adversely affect the fund's performance to the extent that the fund is delayed in investing new cash and is required to maintain a larger cash position than it ordinarily would. These transactions may also accelerate the realization of taxable income to shareholders if such sales of investments resulted in gains, and may also increase transaction costs. In addition, a large redemption could result in the fund's current expenses being allocated over a smaller asset base, leading to an increase in the fund's expense ratio. These risks are heightened when the fund is small.

In addition to the principal investment strategies described above, the fund has other investment practices that are described in the statement of additional information, which includes a description of other risks related to the fund's principal investment strategies and other investment practices. The fund's investment results will depend on the ability of the fund's investment adviser to navigate the risks discussed above as well as those described in the statement of additional information.

**Fund comparative indexes** — The MSCI ACWI IMI Index is a free float-adjusted market capitalization-weighted index that is designed to measure the equity market results of large, mid, and small capitalization companies in both developed and emerging markets. The index consists of more than 40 developed and emerging market country indexes. Results reflect dividends net of withholding taxes. This index is unmanaged, and its results include reinvested dividends and/or distributions but do not reflect the effect of sales charges, commissions, account fees, expenses or U.S. federal income taxes.The MSCI All Country World Small Cap Index is a free float-adjusted market capitalization-weighted index that is designed to measure equity market results of smaller capitalization companies in both developed and emerging markets. Results reflect dividends net of withholding taxes. This index is unmanaged, and its results include reinvested dividends and/or distributions but do not reflect the effect of sales charges, commissions, account fees, expenses or U.S. federal income taxes.

**Portfolio holdings** A description of the fund's policies and procedures regarding disclosure of information about its portfolio holdings is available in the statement of additional information.

**EUPAC Fund** The fund's investment objective is to provide you with long-term growth of capital. While it has no present intention to do so, the fund's board may change the fund's investment objective without shareholder approval upon 60 days' written notice to shareholders.

The fund is designed for investors seeking capital appreciation and diversification through investments in common stocks and other equity-type securities (including depositary receipts), consistent with the fund's investment objective.

Investors in the fund should have a long-term perspective and be able to tolerate potentially sharp declines in value.

The following describes certain strategies that the investment adviser uses in pursuit of the fund's investment objective and the corresponding risks:

The fund invests primarily in common stocks in Europe and the Pacific Basin that the investment adviser believes have the potential for growth. Growth stocks are stocks that the investment adviser believes have the potential for above-average capital appreciation.

Normally, the fund will invest at least 80% of its net assets in securities of issuers in Europe and the Pacific Basin. This policy is subject to change only upon 60 days' notice to shareholders. A country will be considered part of Europe if it is part of the MSCI European indexes, and part of the Pacific Basin if any of its borders touches the Pacific Ocean. In determining the domicile of an issuer, the fund's investment adviser will generally look to the determination of MSCI Inc. (MSCI) for equity securities and Bloomberg for debt securities. In certain limited circumstances (including where relevant data is unavailable or the nature of a holding warrants special considerations), the adviser may also take into account additional factors, as applicable, including where the issuer's securities are listed; where the issuer is legally

organized, maintains principal corporate offices, conducts its principal operations, generates revenues and/or has credit risk exposure; and the source of guarantees, if any, of such securities. The fund may invest a portion of its assets in common stocks and other securities of companies in emerging markets.

The fund may also hold cash, cash equivalents and fixed-income securities, including commercial paper and short-term securities issued by the U.S. government, its agencies and instrumentalities. The percentage of the fund invested in such holdings varies and depends on various factors, including market conditions and purchases and redemptions of fund shares. The investment adviser may determine that it is appropriate to invest a substantial portion of the fund's assets in such instruments in response to certain circumstances, such as periods of market turmoil. For temporary defensive purposes, the fund may invest without limitation in such instruments. A larger percentage of such holdings could moderate the fund's investment results in a period of rising market prices. Alternatively, a larger percentage of such holdings could reduce the magnitude of the fund's loss in a period of falling market prices and provide liquidity to make additional investments or to meet redemptions.

The fund may invest in certain other funds managed by the investment adviser or its affiliates ("Central Funds") to more effectively invest in a diversified set of securities in a specific asset class such as money market instruments, bonds and other securities. Shares of Central Funds are only offered for purchase to the fund's investment adviser and its affiliates and other funds, investment vehicles and accounts managed by the fund's investment adviser and its affiliates. Central Funds do not charge management fees. As a result, the fund does not bear additional management fees when investing in Central Funds, but the fund does bear its proportionate share of Central Fund expenses. The investment results of the portions of the fund's assets invested in the Central Funds will be based upon the investment results of the Central Funds.

The fund may also lend portfolio securities to brokers, dealers and other institutions that provide cash or U.S. Treasury securities as collateral in an amount at least equal to the value of the securities loaned.

Prior to May 1, 2026, the fund was called International Fund.

The fund relies on the professional judgment of its investment adviser to make decisions about the fund's portfolio investments. The basic investment philosophy of the investment adviser is to seek to invest in attractively valued companies that, in its opinion, represent good, long-term investment opportunities. The investment adviser believes that an important way to accomplish this is through fundamental analysis, which may include meeting with company executives and employees, suppliers, customers and competitors. Securities may be sold when the investment adviser believes that they no longer represent relatively attractive investment opportunities.

The investment adviser may consider environmental, social and governance ("ESG") factors that, depending on the facts and circumstances, are material to the value of an issuer or instrument. ESG factors may include, but are not limited to, environmental issues (e.g., water use, emission levels, waste, environmental remediation), social issues (e.g., human capital, health and safety, changing customer behavior) or governance issues (e.g., board composition, executive compensation, shareholder dilution).

The following are principal risks associated with investing in the fund.

*Market conditions* — The prices of, and the income generated by, the common stocks and other securities held by the fund may decline – sometimes rapidly or unpredictably – due to various factors, including events or conditions affecting the general economy or particular industries or companies; overall market changes; local, regional or global political, social or economic instability; governmental, governmental agency or central bank responses to economic conditions; levels of public debt and deficits; changes in inflation rates; and currency exchange rate, interest rate and commodity price fluctuations.

Economic, financial or political events, trading and tariff arrangements, wars, terrorism, cybersecurity events, natural disasters, public health emergencies (such as the spread of infectious disease), bank failures and other circumstances in one country or region, including actions taken by governmental or quasi-governmental authorities in response to any of the foregoing, could have impacts on global economies or markets. As a result, whether or not the fund invests in securities of issuers located in or with significant exposure to the countries affected, the value and liquidity of the fund's investments may be negatively affected by developments in other countries and regions.

political, social, economic or market developments (including social instability, regional conflicts, terrorism and war) in the countries or regions in which the issuers are domiciled, operate or generate revenue or to which the securities are tied economically. These securities may also lose value due to changes in foreign currency exchange rates against the U.S. dollar and/or currencies of other countries. Issuers of these securities may be more susceptible to actions of foreign governments, such as nationalization, currency blockage or the imposition of price controls, sanctions, or punitive taxes, each of which could adversely impact the value of these securities.

For example, if the fund has significant exposure in a particular country, then social, economic, regulatory or other issues that negatively affect that country may have a greater impact on the fund than on a fund that is more geographically diversified.

*Investing in depositary receipts* — Depositary receipts are securities that evidence ownership interests in, and represent the right to receive, a security or a pool of securities that have been deposited with a bank or trust depository. Such securities may be less liquid or may trade at a lower price than the underlying securities of the issuer. Additionally, receipt of corporate information about the underlying issuer and proxy disclosure may not be timely and there may not be a correlation between such information and the market value of the depositary receipts.

*Liquidity risk* — Certain fund holdings may be or may become difficult or impossible to sell, particularly during times of market turmoil. Liquidity may be impacted by the lack of an active market for a holding, legal or contractual restrictions on resale, or the reduced number and capacity of market participants to make a market in such holding.

**Management and organization**

**Investment adviser** Capital Research and Management Company, an experienced investment management organization founded in 1931, serves as the investment adviser to the Series and other funds, including the American Funds. Capital Research and Management Company is a wholly owned subsidiary of The Capital Group Companies, Inc. and is located at 333 South Hope Street, Los Angeles, California 90071. Capital Research and Management Company manages the investment portfolios and business affairs of the Series. The total management fee paid by each fund to its investment adviser for the most recent fiscal year, including any amounts waived, in each case expressed as a percentage of average net assets of that fund, appears in the Annual Fund Operating Expenses table for each fund. Please see the statement of additional information for further details. A discussion regarding the basis for the approval of the Series' Investment Advisory and Service Agreement by the Series' board of trustees is contained in the Series' annual or semi-annual report in Form N-CSR for the most recent fiscal period.

Capital Research and Management Company manages equity assets through three equity investment divisions and fixed income assets through its fixed income investment division, Capital Fixed Income Investors. The three equity investment divisions — Capital International Investors, Capital Research Global Investors and Capital World Investors — make investment decisions independently of one another.

The equity investment divisions may, in the future, be incorporated as wholly owned subsidiaries of Capital Research and Management Company. In that event, Capital Research and Management Company would continue to be the investment adviser, and day-to-day investment management of equity assets would continue to be carried out through one or more of these subsidiaries. Although not currently contemplated, Capital Research and Management Company could incorporate its fixed income investment division in the future and engage it to provide day-to-day investment management of fixed income assets. Capital Research and Management Company and each of the funds it advises have received an exemptive order from the U.S. Securities and Exchange Commission that allows Capital Research and Management Company to use, upon approval of the funds' boards, its management subsidiaries and affiliates to provide day-to-day investment management services to the funds, including making changes to the management subsidiaries and affiliates providing such services. The Series' shareholders approved this arrangement; however, there is no assurance that Capital Research and Management Company will incorporate its investment divisions or exercise any authority granted to it under the exemptive order.

In addition, shareholders of the Series have approved a proposal to reorganize the Series into a Delaware statutory trust. However, the Series reserved the right to delay implementing the reorganization and has elected to do so.

**The Capital System<sup>TM</sup>** Capital Research and Management Company uses a system of multiple portfolio managers in managing fund assets. Under this approach, the portfolio of a fund is divided into segments managed by individual managers. In addition, Capital Research and Management Company's investment analysts may make investment decisions with respect to a portion of each underlying fund's portfolio. Investment decisions are subject to a fund's objective(s), policies and restrictions and the oversight of the appropriate investment-related committees of Capital Research and Management Company and its investment divisions.

Certain senior members of Capital Fixed Income Investors, the investment adviser's fixed income investment division, serve on the Portfolio Strategy Group. The group utilizes a research-driven process with input from the investment adviser's analysts, portfolio managers and economists to define investment themes on a range of macroeconomic factors, including duration, yield curve and sector allocation. Where applicable, the investment decisions made by a fund's fixed income portfolio managers are informed by the investment themes discussed by the group.

Information regarding the portfolio managers' compensation, their ownership of securities in the Series and other accounts they manage is in the statement of additional information.

17&nbsp;&nbsp;&nbsp;&nbsp; American Funds Insurance Series / Prospectus

------

**Purchases and redemptions of shares** Shares of the Series are currently offered only to insurance company separate accounts as well as so-called "feeder funds" under master-feeder arrangements sponsored by insurance companies as underlying investments for such insurance companies' variable annuity contracts and variable life insurance policies. All such shares may be purchased or redeemed by the insurance company separate accounts (or feeder funds) at net asset value without any sales or redemption charges. These purchases and redemptions are made at the price next determined after such purchases and redemptions of units of the separate accounts (or feeder funds). The Series typically expects to remit redemption proceeds one business day following receipt and acceptance of a redemption order, regardless of the method the Series uses to make such payment (e.g., check, wire or automated clearing house transfer). However, payment may take longer than one business day and may take up to seven days as generally permitted by the Investment Company Act of 1940, as amended (the "1940 Act"). Under the 1940 Act, the Series may be permitted to pay redemption proceeds beyond seven days under certain limited circumstances.

Under normal conditions, the Series typically expects to meet shareholder redemptions from a reserve of highly liquid assets, such as cash or cash equivalents. The Series may use additional methods to meet shareholder redemptions, if they become necessary. These methods may include, but are not limited to, the sale of portfolio assets, the use of overdraft protection afforded by the Series' custodian bank, borrowing from a line of credit and making payment with fund securities or other fund assets rather than in cash (as further discussed in the following paragraph).

Although payment of redemptions normally will be in cash, the Series may pay the redemption price wholly or partly with portfolio securities or other fund assets under conditions and circumstances determined by the Series' board of trustees. On the same redemption date, some shareholders may be paid in whole or in part in securities (which may differ among those shareholders), while other shareholders may be paid entirely in cash. In general, in-kind redemptions to affiliated shareholders will as closely as practicable represent the affiliated shareholder's pro rata share of the Series' securities, subject to certain exceptions. Securities distributed in-kind to unaffiliated shareholders will be selected by the investment adviser in a manner the investment adviser deems to be fair and reasonable to the Series' shareholders. The disposal of the securities received in-kind may be subject to brokerage costs and, until sold, such securities remain subject to market risk and liquidity risk, including the risk that such securities are or become difficult to sell. If the Series pays your redemption with illiquid or less liquid securities, you will bear the risk of not being able to sell such securities.

**Frequent trading of fund shares** The Series and Capital Client Group, Inc., the Series' distributor, reserve the right to reject any purchase order for any reason. The funds are not designed to serve as vehicles for frequent trading. Frequent trading of fund shares may lead to increased costs to the funds and less efficient management of the funds' portfolios, potentially resulting in dilution of the value of the shares held by long-term shareholders. Accordingly, purchases, including those that are part of exchange activity, that the Series or Capital Client Group, Inc. has determined could involve actual or potential harm to a fund may be rejected.

The Series, through its transfer agent, American Funds Service Company, has agreements with the Series' insurance relationships to maintain its surveillance procedures that are designed to detect frequent trading in fund shares. The agreements generally require the insurance companies to (i) provide, upon request from a fund, the Series or their agent, certain identifying and account information regarding contract owners who invest in fund shares through an insurance company account and (ii) execute instructions from a fund, the Series or their agent to restrict further purchases or exchanges of fund shares by a contract owner who the Series has identified as having engaged in potentially harmful market timing or frequent trading. Under these procedures, various analytics are used to evaluate factors that may be indicative of frequent trading. For example, transactions in fund shares that exceed certain monetary thresholds may be scrutinized. American Funds Service Company may work with the insurance company separate accounts or feeder funds to apply their procedures that American Funds Service Company believes are reasonably designed to enforce the frequent trading policies of the Series. You should refer to disclosures provided by the insurance company with which you have a contract to determine the specific trading restrictions that apply to you.

Under the Series' frequent trading policy, certain trading activity will not be treated as frequent trading, such as:

· retirement plan contributions, loans and distributions (including hardship withdrawals) identified as such on the retirement plan recordkeeper's system;

· purchases and redemptions in community foundation accounts;

· purchase transactions involving in-kind transfers of fund shares, if the entity maintaining the contract owner's account is able to identify the transaction as one of these types of transactions;

· transactions by certain intermediaries in accordance with established hedging programs approved by the fund's investment adviser; and

· systematic redemptions and purchases if the entity maintaining the contract owner's account is able to identify the transaction as a systematic redemption or purchase.

Generally, purchases and redemptions will not be considered "systematic" unless the transaction is prescheduled for a specific date.

American Funds Service Company will monitor for other types of activity that could potentially be harmful to the Series – for example short-term trading activity in multiple funds. If American Funds Service Company identifies any activity that may constitute frequent trading, it reserves the right to contact the insurance company separate account or feeder fund and request that the separate account or feeder fund either provide information regarding an account owner's transactions or restrict the account owner's trading. If American Funds Service Company is not satisfied that insurance company separate account or feeder fund has taken appropriate action, American Funds Service Company may terminate the separate account's or feeder fund's ability to transact in fund shares.

There is no guarantee that all instances of frequent trading in fund shares will be prevented.

**Notwithstanding the Series' surveillance procedures described above, all transactions in fund shares remain subject to the right of the Series, Capital Client Group, Inc. and American Funds Service Company to restrict potentially abusive trading generally, including the types of transactions described above that will not be prevented.**

**Valuing shares** The net asset value of each share class of a fund is the value of a single share of that class. Net asset value is computed by adding a class's share of the value of a fund's investments, cash and other assets, subtracting the class's share of the fund's liabilities allocated to the class, and dividing the result by the number of shares of that class that are outstanding. Realized investment income and gain is included in the fund's net asset value until the ex-dividend date, when the declared dividend amount is treated as a fund liability. The net asset value per share is calculated once daily as of the close of regular trading on the New York Stock Exchange, normally 4 p.m. New York time, each day the New York Stock Exchange is open. If the New York Stock Exchange makes a scheduled (e.g., the day after Thanksgiving) or an unscheduled close prior to 4 p.m. New York time, the net asset value of each fund will be determined at approximately the time the New York Stock Exchange closes on that day. If on such a day market quotations and prices from third-party pricing services are not based as of the time of the early close of the New York Stock Exchange but are as of a later time (up to approximately 4 p.m. New York time), for example because the market remains open after the close of the New York Stock Exchange, those later market quotations and prices will be used in determining the funds' net asset value.

Equity securities are valued primarily on the basis of market quotations, and debt securities are valued primarily on the basis of prices from third-party pricing services due to the lack of market quotations. Futures contracts are valued primarily on the basis of settlement prices. The funds' portfolio investments are valued in accordance with procedures for making fair value determinations if market quotations are not readily available, including procedures to determine the representativeness of third-party vendor prices, or in the event market quotations or third-party vendor prices are not considered reliable. For example, if events occur between the close of markets outside the United States and the close of regular trading on the New York Stock Exchange that, in the opinion of the investment adviser, materially affect the value of any of the funds' equity securities that trade principally in those international markets, those securities will be valued in accordance with fair value procedures. Similarly, fair value procedures will be employed if an issuer defaults on its debt securities and there is no market for its securities. Use of these procedures is intended to result in more appropriate net asset values and, where applicable, to reduce potential arbitrage opportunities otherwise available to short-term investors.

Because certain of the funds may hold securities that are listed primarily on foreign exchanges that trade on weekends or days when the funds do not price their shares, the values of securities held in the funds may change on days when you will not be able to purchase or redeem fund shares.

Shares of the funds will be purchased or sold at the net asset value next determined after receipt of requests from the appropriate insurance company. Requests received by the appropriate insurance company prior to 4 p.m. New York time and communicated by the insurance company to the Series or its agent will be purchased or sold at that day's net asset value. Orders in good order received after the New York Stock Exchange closes (scheduled or unscheduled) will be processed at the net asset value (plus any applicable sales charge) calculated on the following business day.

**Plan of distribution** The Series has adopted a plan of distribution or "12b-1 plan" for Class 1A shares under which it may finance activities intended primarily to sell shares, provided that the categories of expenses are approved in advance by the Series' board of trustees. The plan provides for annual expenses of .25% for Class 1A shares; however, the Series' board of trustees has not authorized any payments under the plan.

**Other compensation to dealers** Capital Client Group, Inc., at its expense, provides additional compensation to insurance companies. These payments may be made, at the discretion of Capital Client Group, Inc., to insurance companies (or their affiliates) that have sold shares of the funds of the American Funds Insurance Series and American Funds as the exclusive underlying investments to their variable annuity contracts. A number of factors will be considered in determining payments, including the sales, assets, and the quality of the insurance company's relationship with Capital Client Group, Inc. The payment will typically be determined using a formula applied consistently to insurance companies based on the relevant facts and circumstances. Aggregate payments made by Capital Client Group, Inc. to insurance companies may also change from year to year. Only assets and deposits in variable annuity contracts that offer exclusively shares of the funds of the American Funds Insurance Series and American Funds are included in the formula. Further, assets for which the insurance company, or an affiliated broker-dealer, acts as an ERISA investment fiduciary are generally excluded from the formula. Capital Client Group, Inc. makes these payments to help defray the costs incurred by qualifying insurance companies in connection with efforts to educate their sales force about the American Funds Insurance Series and American Funds so that they help financial advisers make recommendations and provide services that are suitable and meet contractholders' needs. These payments may also be made to help defray the costs associated with the insurance company's provision of account-related services and activities and support the insurance company's distribution activities. Capital Client Group, Inc. will, on a periodic basis, determine the advisability of continuing these payments. As of May 1, 2026, the insurance companies (or their affiliates) that Capital Client Group, Inc. anticipates will receive additional compensation based on prior payments include Lincoln National Life Insurance Co.

Firms receiving additional compensation payments must sign a letter acknowledging the purpose of the payment and Capital Client Group, Inc.'s goal that the payment will help facilitate education of their sales force about the American Funds Insurance Series and American Funds to help financial professionals make suitable recommendations and better serve their clients who invest in the funds as underlying investments to variable annuity contracts. The letters generally require the firms to (1) offers shares of the funds of the American Funds Insurance Series and American Funds as the exclusive underlying investments to their variable annuity contracts, and (2) provide Capital Client Group, Inc. broad access to their sales force and product platforms and develop a business plan to achieve such access.

Capital Client Group, Inc. may also pay expenses associated with meetings and other training and educational opportunities conducted by insurance companies, selling dealers, advisory platform providers and other intermediaries to facilitate educating financial professionals and shareholders about the American Funds Insurance Series and American Funds. For example, some of these expenses may include, but not be limited to, meeting sponsor fees, meeting location fees, fees for data and reporting, and fees to obtain lists of financial professionals to better tailor training and education opportunities. In addition, Capital Client Group, Inc. and/or its affiliates may make payments to third parties for platform fees and other services.

If investment advisers, distributors or other affiliates of mutual funds pay additional compensation or other incentives to insurance companies in differing amounts, insurance companies and the financial professionals with which they interact may have financial incentives for recommending a particular mutual fund over other mutual funds or investments, creating a potential conflict of interest. You should consult with your financial professional and review carefully any disclosure by your financial professional's firm as to compensation received.

**Fund expenses** In periods of market volatility, assets of the funds may decline significantly, causing total annual fund operating expenses (as a percentage of the value of your investment) to become higher than the numbers shown in the Annual Fund Operating Expenses tables in this prospectus.

The "Other expenses" items in the Annual Fund Operating Expenses tables in this prospectus are based on expenses as of each fund's most recently completed fiscal year. These items include third-party expenses, such as custodial, legal, audit, accounting, regulatory reporting and pricing vendor services, and an administrative services fee payable to the Series' investment adviser for administrative services provided by the Series' investment adviser and its affiliates. In addition, the "Other expenses" items for Class 1A shares include fees for administrative services provided by the insurance companies that include Class 1A shares of any of the funds as underlying investments in their variable contracts. Each fund will pay an insurance administration fee of .25% of Class 1A share assets to these insurance companies for providing certain services pursuant to an insurance administrative services plan adopted by the Series.

For all share classes, "Other expenses" items in the Annual Fund Operating Expenses table in this prospectus include fees for administrative services provided by the fund's investment adviser and its affiliates. Administrative services are provided by the investment adviser and its affiliates to help assist third parties providing non-distribution services to fund shareholders. These services include providing in-depth information on the fund and market developments that impact fund investments. Administrative services also include, but are not limited to, coordinating, monitoring and overseeing third parties that provide services to fund shareholders.

The Administrative Services Agreement between the fund and the investment adviser provides the fund the ability to charge an administrative services fee of .05% for all share classes. The fund's investment adviser receives an administrative services fee at the annual rate of .03% of the average daily net assets of the fund attributable to all share classes (which could be increased as noted above) for its provision of administrative services.

**Investment results** All fund results in the "Investment results" section of this prospectus reflect the reinvestment of dividends and capital gains distributions, if any. Unless otherwise noted, fund results reflect any fee waivers and/or expense reimbursements in effect during the period presented.

**Distributions and taxes** Each fund of the Series intends to qualify as a "regulated investment company" under the Internal Revenue Code. In any fiscal year in which a fund so qualifies and distributes to shareholders its investment company taxable income and net realized capital gain, the fund itself is relieved of federal income tax.

It is the Series' policy to distribute to the shareholders (the insurance company separate accounts) all of its investment company taxable income and capital gain for each fiscal year.

#### See the applicable contract prospectus for information regarding the federal income tax treatment of the contracts and distributions to the separate accounts.

**Financial highlights** The Financial Highlights table is intended to help you understand a fund's results for the past five fiscal years (or, if shorter, the period of operations). Certain information reflects financial results for a single share of a particular class. The total returns in the table represent the rate that an investor would have earned or lost on an investment in a fund (assuming reinvestment of all dividends and capital gain distributions). Where indicated, figures in the table reflect the impact, if any, of certain waivers from Capital Research and Management Company. For more information about these waivers, see the fund's statement of additional information and Form N-CSR. The information in the Financial Highlights table has been audited by PricewaterhouseCoopers LLP, whose current report, along with the funds' financial statements, is included in the statement of additional information, which is available upon request. Figures shown do not reflect insurance contract fees and expenses. If insurance contract fees and expenses were reflected, results would be lower.

 **SMALLCAP World Fund** 

**Investment objective** The fund's investment objective is to provide you with long-term growth of capital.

**Fees and expenses of the fund** This table describes the fees and expenses that you may pay if you buy, hold and sell an interest in Class 2 shares of the fund. **You may pay other fees, such as insurance contract fees and expenses, which are not reflected in the tables and examples below.** If insurance contract fees and expenses were reflected, expenses shown would be higher.

|:---|:---|
| **Annual fund operating expenses (expenses that you pay each year as a percentage of the net asset value of your investment)** | Class 2 |
| Management fee | 0.65% |
| Distribution and/or service (12b-1) fees | 0.25 |
| Other expenses | 0.05 |
| Total annual fund operating expenses | 0.95 |
| Fee waiver\* | 0.05 |
| Total annual fund operating expenses after fee waiver | 0.90 |

---

<sup>\*</sup> The investment adviser is currently waiving a portion of its management fee equal to 0.05% of the fund's net assets. This waiver will be in effect through at least May 1, 2027. The waiver may only be modified or terminated with the approval of the fund's board.

**Example** This example is intended to help you compare the cost of investing in Class 2 shares of the fund with the cost of investing in other mutual funds.

The example assumes that you invest $10,000 in the fund for the time periods indicated and then redeem or hold all of your shares at the end of those periods. The example also assumes that your investment has a 5% return each year and that the fund's operating expenses remain the same. The example does not reflect insurance contract expenses. If insurance contract expenses were reflected, expenses shown would be higher. The example reflects the fee waiver described above through the expiration date of such waiver and total annual fund operating expenses thereafter. No sales charge (load) or other fees are charged by the fund upon redemption, so you would incur these hypothetical costs whether or not you were to redeem your shares at the end of the given period. Although your actual costs may be higher or lower, based on these assumptions your costs would be:

|:---|:---|:---|:---|:---|
|  | 1 year | 3 years | 5 years | 10 years |
| Class 2 | $92 | $298 | $521 | $1162 |

---

**Portfolio turnover** The fund pays transaction costs, such as commissions, when it buys and sells securities (or "turns over" its portfolio). A higher portfolio turnover rate may indicate higher transaction costs. These costs, which are not reflected in annual fund operating expenses or in the example, affect the fund's investment results. During the most recent fiscal year, the fund's portfolio turnover rate was 51% of the average value of its portfolio.

**Principal investment strategies** Normally the fund invests at least 80% of its net assets in common stocks and other equity-type securities (such as preferred stocks, convertible preferred stocks and convertible bonds) of companies with small market capitalizations, including growth-oriented stocks. The investment adviser currently defines "small market capitalization" companies to be companies with market capitalizations within or below the capitalization range of companies included in the MSCI All Country World Small Cap Index or the Russell 2000 Index, measured based on the maximum market capitalization of companies in either index within the last 12 months. As of August 31, 2025, the largest company in the MSCI All Country World Small Cap Index had a market capitalization of approximately $25.9 billion and the largest company in the Russell 2000 Index had a market capitalization of approximately $20.9 billion. The market capitalization of the companies included in the MSCI All Country World Small Cap Index and the Russell 2000 Index will change with market conditions. The investment adviser has periodically re-evaluated and adjusted this definition and may continue to do so in the future. The fund may continue to hold securities of a portfolio company that subsequently appreciates above the small market capitalization threshold. Under normal circumstances, the fund will invest a significant portion of its assets outside the United States, including in emerging markets.

Prior to May 1, 2026, the fund was called Global Small Capitalization Fund.

The investment adviser uses a system of multiple portfolio managers in managing the fund's assets. Under this approach, the portfolio of the fund is divided into segments managed by individual managers.

The fund relies on the professional judgment of its investment adviser to make decisions about the fund's portfolio investments. The basic investment philosophy of the investment adviser is to seek to invest in attractively valued companies that, in its opinion, represent good, long-term investment opportunities. Securities may be sold when the investment adviser believes that they no longer represent relatively attractive investment opportunities.

**Principal risks This section describes the principal risks associated with investing in the fund. You may lose money by investing in the fund. The likelihood of loss may be greater if you invest for a shorter period of time.** 

*Market conditions* — The prices of, and the income generated by, the securities held by the fund may decline – sometimes rapidly or unpredictably – due to various factors, including events or conditions affecting the general economy or particular industries or companies; overall market changes; local, regional or global political, social or economic instability; governmental, governmental agency or central bank responses to economic conditions; levels of public debt and deficits; changes in inflation rates; and currency exchange rate, interest rate and commodity price fluctuations.

Economies and financial markets throughout the world are highly interconnected. Economic, financial or political events, trading and tariff arrangements, wars, terrorism, cybersecurity events, natural disasters, public health emergencies (such as the spread of infectious disease), bank failures and other circumstances in one country or region, including actions taken by governmental or quasi-governmental authorities in response to any of the foregoing, could have impacts on global economies or markets. As a result, whether or not the fund invests in securities of issuers located in or with significant exposure to the countries affected, the value and liquidity of the fund's investments may be negatively affected by developments in other countries and regions.

*Issuer risks* — The prices of, and the income generated by, securities held by the fund may decline in response to various factors directly related to the issuers of such securities, including reduced demand for an issuer's goods or services, poor management performance, major litigation, investigations or other controversies related to the issuer, changes in the issuer's financial condition or credit rating, changes in government regulations affecting the issuer or its competitive environment and strategic initiatives such as mergers, acquisitions or dispositions and the market response to any such initiatives. An individual security may also be affected by factors relating to the industry or sector of the issuer or the securities markets as a whole, and conversely an industry or sector or the securities markets may be affected by a change in financial condition or other event affecting a single issuer.

*Investing in growth-oriented stocks* — Growth-oriented common stocks and other equity-type securities (such as preferred stocks, convertible preferred stocks and convertible bonds) may involve larger price swings and greater potential for loss than other types of investments. These risks may be even greater in the case of smaller capitalization stocks.

*Investing in small companies* — Investing in smaller companies may pose additional risks. For example, it is often more difficult to value or dispose of small company stocks and more difficult to obtain information about smaller companies than about larger companies. Furthermore, smaller companies often have limited product lines, operating histories, markets and/or financial resources, may be dependent on one or a few key persons for management, and can be more susceptible to losses. Moreover, the prices of their stocks may be more volatile than stocks of larger, more established companies, particularly during times of market turmoil.

*Investing outside the United States* — Securities of issuers domiciled outside the United States or with significant operations or revenues outside the United States, and securities tied economically to countries outside the United States, may lose value because of adverse political, social, economic or market developments (including social instability, regional conflicts, terrorism and war) in the countries or regions in which the issuers are domiciled, operate or generate revenue or to which the securities are tied economically. These securities may also lose value due to changes in foreign currency exchange rates against the U.S. dollar and/or currencies of other countries. Issuers of these securities may be more susceptible to actions of foreign governments, such as nationalization, currency blockage or the imposition of price controls, sanctions, or punitive taxes, each of which could adversely impact the value of these securities. Securities markets in certain countries may be more volatile and/or less liquid than those in the United States. Investments outside the United States may also be subject to different regulatory, legal, accounting, auditing, financial reporting and recordkeeping requirements, and may be more difficult to value, than those in the United States. In addition, the value of investments outside the United States may be reduced by foreign taxes, including foreign withholding taxes on interest and dividends. Further, there may be increased risks of delayed settlement of securities purchased or sold by the fund, which could impact the liquidity of the fund's portfolio. The risks of investing outside the United States may be heightened in connection with investments in emerging markets.

*Investing in emerging markets* — Investing in emerging markets may involve risks in addition to and greater than those generally associated with investing in the securities markets of developed countries. For instance, emerging market countries tend to have less developed political, economic and legal systems than those in developed countries. Accordingly, the governments of these countries may be less stable and more likely to intervene in the market economy, for example, by imposing capital controls, nationalizing a company or industry, placing restrictions on foreign ownership and on withdrawing sale proceeds of securities from the country, and/or imposing punitive taxes that could adversely affect the prices of securities. Information regarding issuers in emerging markets may be limited, incomplete or inaccurate, and such issuers may not be subject to regulatory, accounting, auditing, and financial reporting and recordkeeping standards comparable to those to which issuers in more developed markets are subject. The fund's rights with respect to its investments in emerging markets, if any, will generally be governed by local law, which may make it difficult or impossible for the fund to pursue legal remedies or to obtain and enforce judgments in local courts. In addition, the economies of these countries may be dependent on relatively few industries, may have limited access to capital and may be more susceptible to changes in local and global trade conditions and downturns in the world economy. Securities markets in these countries can also be relatively small and have substantially lower trading volumes. As a result, securities issued in these countries may be more volatile and less liquid, more vulnerable to market manipulation, and more difficult to value, than securities issued in countries with more developed economies and/or markets. Less certainty with respect to security valuations may lead to additional challenges and risks in calculating the fund's net asset value. Additionally, emerging markets are more likely to experience problems with the clearing and settling of trades and the holding of securities by banks, agents and depositories that are less established than those in developed countries.

------

*Liquidity risk* — Certain fund holdings may be or may become difficult or impossible to sell, particularly during times of market turmoil. Liquidity may be impacted by the lack of an active market for a holding, legal or contractual restrictions on resale, or the reduced number and capacity of market participants to make a market in such holding. Market prices for less liquid or illiquid holdings may be volatile or difficult to determine, and reduced liquidity may have an adverse impact on the market price of such holdings. Additionally, the sale of less liquid or illiquid holdings may involve substantial delays (including delays in settlement) and additional costs and the fund may be unable to sell such holdings when necessary to meet its liquidity needs or to try to limit losses, or may be forced to sell at a loss.

*Management* — The investment adviser to the fund actively manages the fund's investments. Consequently, the fund is subject to the risk that the methods and analyses, including models, tools and data, employed by the investment adviser in this process may be flawed or incorrect and may not produce the desired results. This could cause the fund to lose value or its investment results to lag relevant benchmarks or other funds with similar objectives.

Your investment in the fund is not a bank deposit and is not insured or guaranteed by the Federal Deposit Insurance Corporation or any other governmental agency, entity or person. You should consider how this fund fits into your overall investment program.

**Investment results** The following bar chart shows how the investment results of the Class 2 shares of the fund have varied from year to year, and the following table shows how the fund's average annual total returns for various periods compare with a broad measure of securities market results and, if applicable, other measures of market results that reflect the fund's investment universe. This information provides some indication of the risks of investing in the fund. Past investment results (before and after taxes) are not predictive of future investment results. Figures shown reflect fees and expenses associated with an investment in the fund, but do not reflect insurance contract fees and expenses. If insurance contract fees and expenses were included, results would have been lower. Updated information on the fund's investment results can be obtained by visiting capitalgroup.com/afis.

**Purchase and sale of fund shares** Shares of the fund are not sold directly to the general public. The fund is offered only as an underlying investment option for variable insurance contracts, and insurance company separate accounts and qualified feeder funds — and not the holders of variable insurance contracts — are the shareholders of the fund. Although the fund does not require a minimum amount for initial or subsequent purchases from insurance companies, your insurance company may impose investment minimums for your purchase of the fund.

You may sell (redeem) shares on any business day. You must sell (redeem) shares through your insurance company.

**Tax information** See your variable insurance contract prospectus for information regarding the federal income tax treatment of your variable insurance contract and related distributions.

**Payments to broker-dealers and other financial intermediaries** The fund is not sold directly to the general public but instead is offered as an underlying investment option for variable insurance contracts. The fund and its related companies may make payments to the sponsoring insurance company (or its affiliates) for distribution and/or other services. These payments may be a factor that the insurance company considers in including the fund as an underlying investment option in the variable insurance contract. The prospectus (or other offering document) for your variable insurance contract may contain additional information about these payments.

 **EUPAC Fund** 

**Investment objective** The fund's investment objective is to provide you with long-term growth of capital.

**Fees and expenses of the fund** This table describes the fees and expenses that you may pay if you buy, hold and sell an interest in Class 2 shares of the fund. **You may pay other fees, such as insurance contract fees and expenses, which are not reflected in the tables and examples below.** If insurance contract fees and expenses were reflected, expenses shown would be higher.

---

| | |
|:---|:---|
| **Annual fund operating expenses (expenses that you pay each year as a percentage of the net asset value of your investment)** | Class 2 |
| Management fee | 0.48% |
| Distribution and/or service (12b-1) fees | 0.25 |
| Other expenses | 0.05 |
| Total annual fund operating expenses | 0.78 |
| Fee waiver\* | 0.06 |
| Total annual fund operating expenses after fee waiver | 0.72 |

---

\* The investment adviser is currently waiving a portion of its management fee equal to 0.06% of the fund's net assets. This waiver will be in effect through at least May 1, 2027. The waiver may only be modified or terminated with the approval of the fund's board.

**Example** This example is intended to help you compare the cost of investing in Class 2 shares of the fund with the cost of investing in other mutual funds.

The example assumes that you invest $10,000 in the fund for the time periods indicated and then redeem or hold all of your shares at the end of those periods. The example also assumes that your investment has a 5% return each year and that the fund's operating expenses remain the same. The example does not reflect insurance contract expenses. If insurance contract expenses were reflected, expenses shown would be higher. The example reflects the fee waiver described above through the expiration date of such waiver and total annual fund operating expenses thereafter. No sales charge (load) or other fees are charged by the fund upon redemption, so you would incur these hypothetical costs whether or not you were to redeem your shares at the end of the given period. Although your actual costs may be higher or lower, based on these assumptions your costs would be:

---

| | | | | |
|:---|:---|:---|:---|:---|
|  | 1 year | 3 years | 5 years | 10 years |
| Class 2 | $74 | $243 | $427 | $960 |

---

**Portfolio turnover** The fund pays transaction costs, such as commissions, when it buys and sells securities (or "turns over" its portfolio). A higher portfolio turnover rate may indicate higher transaction costs. These costs, which are not reflected in annual fund operating expenses or in the example, affect the fund's investment results. During the most recent fiscal year, the fund's portfolio turnover rate was 63% of the average value of its portfolio.

**Principal investment strategies** The fund invests primarily in common stocks in Europe and the Pacific Basin that the investment adviser believes have the potential for growth. Growth stocks are stocks that the investment adviser believes have the potential for above-average capital appreciation.

Normally the fund will invest at least 80% of its net assets in securities of issuers in Europe and the Pacific Basin. A country will be considered part of Europe if it is part of the MSCI European indexes, and part of the Pacific Basin if any of its borders touches the Pacific Ocean. In determining the domicile of an issuer, the fund's investment adviser will generally look to the determination of MSCI Inc. (MSCI) for equity securities and Bloomberg for debt securities. In certain limited circumstances (including where relevant data is unavailable or the nature of a holding warrants special considerations), the adviser may also take into account additional factors, as applicable, including where the issuer's securities are listed; where the issuer is legally organized, maintains principal corporate offices, conducts its principal operations, generates revenues and/or has credit risk exposure; and the source of guarantees, if any, of such securities. The fund may invest a portion of its assets in common stocks and other securities of companies in emerging markets.

Prior to May 1, 2026, the fund was called International Fund.

The investment adviser uses a system of multiple portfolio managers in managing the fund's assets. Under this approach, the portfolio of the fund is divided into segments managed by individual managers.

The fund relies on the professional judgment of its investment adviser to make decisions about the fund's portfolio investments. The basic investment philosophy of the investment adviser is to seek to invest in attractively valued companies that, in its opinion, represent good, long-term investment opportunities. Securities may be sold when the investment adviser believes that they no longer represent relatively attractive investment opportunities.

**Principal risks This section describes the principal risks associated with investing in the fund. You may lose money by investing in the fund. The likelihood of loss may be greater if you invest for a shorter period of time.** 

*Market conditions* — The prices of, and the income generated by, the common stocks and other securities held by the fund may decline – sometimes rapidly or unpredictably – due to various factors, including events or conditions affecting the general economy or particular industries or companies; overall market changes; local, regional or global political, social or economic instability; governmental, governmental agency or central bank responses to economic conditions; levels of public debt and deficits; changes in inflation rates; and currency exchange rate, interest rate and commodity price fluctuations.

Economies and financial markets throughout the world are highly interconnected. Economic, financial or political events, trading and tariff arrangements, wars, terrorism, cybersecurity events, natural disasters, public health emergencies (such as the spread of infectious disease), bank failures and other circumstances in one country or region, including actions taken by governmental or quasi-governmental authorities in response to any of the foregoing, could have impacts on global economies or markets. As a result, whether or not the fund invests in securities of issuers located in or with significant exposure to the countries affected, the value and liquidity of the fund's investments may be negatively affected by developments in other countries and regions.

*Issuer risks* — The prices of, and the income generated by, securities held by the fund may decline in response to various factors directly related to the issuers of such securities, including reduced demand for an issuer's goods or services, poor management performance, major litigation, investigations or other controversies related to the issuer, changes in the issuer's financial condition or credit rating, changes in government regulations affecting the issuer or its competitive environment and strategic initiatives such as mergers, acquisitions or dispositions and the market response to any such initiatives. An individual security may also be affected by factors relating to the industry or sector of the issuer or the securities markets as a whole, and conversely an industry or sector or the securities markets may be affected by a change in financial condition or other event affecting a single issuer.

*Investing in growth-oriented stocks* — Growth-oriented common stocks and other equity-type securities (such as preferred stocks, convertible preferred stocks and convertible bonds) may involve larger price swings and greater potential for loss than other types of investments. These risks may be even greater in the case of smaller capitalization stocks.

*Investing outside the United States* — Securities of issuers domiciled outside the United States or with significant operations or revenues outside the United States, and securities tied economically to countries outside the United States, may lose value because of adverse political, social, economic or market developments (including social instability, regional conflicts, terrorism and war) in the countries or regions in which the issuers are domiciled, operate or generate revenue or to which the securities are tied economically. These securities may also lose value due to changes in foreign currency exchange rates against the U.S. dollar and/or currencies of other countries. Issuers of these securities may be more susceptible to actions of foreign governments, such as nationalization, currency blockage or the imposition of price controls, sanctions, or punitive taxes, each of which could adversely impact the value of these securities. Securities markets in certain countries may be more volatile and/or less liquid than those in the United States. Investments outside the United States may also be subject to different regulatory, legal, accounting, auditing, financial reporting and recordkeeping requirements, and may be more difficult to value, than those in the United States. In addition, the value of investments outside the United States may be reduced by foreign taxes, including foreign withholding taxes on interest and dividends. Further, there may be increased risks of delayed settlement of securities purchased or sold by the fund, which could impact the liquidity of the fund's portfolio. The risks of investing outside the United States may be heightened in connection with investments in emerging markets.

*Investing in emerging markets* — Investing in emerging markets may involve risks in addition to and greater than those generally associated with investing in the securities markets of developed countries. For instance, emerging market countries tend to have less developed political, economic and legal systems than those in developed countries. Accordingly, the governments of these countries may be less stable and more likely to intervene in the market economy, for example, by imposing capital controls, nationalizing a company or industry, placing restrictions on foreign ownership and on withdrawing sale proceeds of securities from the country, and/or imposing punitive taxes that could adversely affect the prices of securities. Information regarding issuers in emerging markets may be limited, incomplete or inaccurate, and such issuers may not be subject to regulatory, accounting, auditing, and financial reporting and recordkeeping standards comparable to those to which issuers in more developed markets are subject. The fund's rights with respect to its investments in emerging markets, if any, will generally be governed by local law, which may make it difficult or impossible for the fund to pursue legal remedies or to obtain and enforce judgments in local courts. In addition, the economies of these countries may be dependent on relatively few industries, may have limited access to capital and may be more susceptible to changes in local and global trade conditions and downturns in the world economy. Securities markets in these countries can also be relatively small and have substantially lower trading volumes. As a result, securities issued in these countries may be more volatile and less liquid, more vulnerable to market manipulation, and more difficult to value, than securities issued in countries with more developed economies and/or markets. Less certainty with respect to security valuations may lead to additional challenges and risks in calculating the fund's net asset value. Additionally, emerging markets are more likely to experience problems with the clearing and settling of trades and the holding of securities by banks, agents and depositories that are less established than those in developed countries.

*Management* — The investment adviser to the fund actively manages the fund's investments. Consequently, the fund is subject to the risk that the methods and analyses, including models, tools and data, employed by the investment adviser in this process may be flawed or incorrect and may not produce the desired results. This could cause the fund to lose value or its investment results to lag relevant benchmarks or other funds with similar objectives.

Your investment in the fund is not a bank deposit and is not insured or guaranteed by the Federal Deposit Insurance Corporation or any other governmental agency, entity or person. You should consider how this fund fits into your overall investment program.

\*Lifetime returns are from May 1, 1990, the date the fund began investment operations. Class 2 shares began investment operations on April 30, 1997; therefore, returns for the fund prior to that date assume a hypothetical investment in Class 1 shares, but reflect the .25% annual expense that applies to Class 2 shares and is described in the "Plan of distribution" section of this prospectus. Returns for Class 1 shares are comparable to those of Class 2 shares because both classes invest in the same portfolio of securities.

**Investment objectives, strategies and risks** 

**SMALLCAP World Fund** The fund's investment objective is to provide you with long-term growth of capital. While it has no present intention to do so, the fund's board may change the fund's investment objective without shareholder approval upon 60 days' prior written notice to shareholders. Normally the fund invests at least 80% of its net assets in common stocks and other equity-type securities (such as preferred stocks, convertible preferred stocks and convertible bonds) of companies with small market capitalizations, including growth-oriented stocks. This policy is subject to change only upon 60 days' prior written notice to shareholders. The investment adviser currently defines "small market capitalization" companies to be companies with market capitalizations within or below the capitalization range of companies included in the MSCI All Country World Small Cap Index or the Russell 2000 Index, measured based on the maximum market capitalization of companies in either index within the last 12 months. As of August 31, 2025, the largest company in the MSCI All Country World Small Cap Index had a market capitalization of approximately $25.9 billion and the largest company in the Russell 2000 Index had a market capitalization of approximately $20.9 billion. The market capitalization of the companies included in the MSCI All Country World Small Cap Index and the Russell 2000 Index will change with market conditions. The investment adviser has periodically re-evaluated and adjusted this definition and may continue to do so in the future. The fund may continue to hold securities of a portfolio company that subsequently appreciates above the small market capitalization threshold. Under normal circumstances, the fund will invest a significant portion of its assets outside the United States, including in emerging markets.

The fund may also hold cash or cash equivalents, including commercial paper and short-term securities issued by the U.S. government, its agencies and instrumentalities. The percentage of the fund invested in such holdings varies and depends on various factors, including market conditions and purchases and redemptions of fund shares. The investment adviser may determine that it is appropriate to invest a substantial portion of the fund's assets in such instruments in response to certain circumstances, such as periods of market turmoil. For temporary defensive purposes, the fund may invest without limitation in such instruments. A larger percentage of such holdings could moderate the fund's investment results in a period of rising market prices. Alternatively, a larger percentage of such holdings could reduce the magnitude of the fund's loss in a period of falling market prices and provide liquidity to make additional investments or to meet redemptions.

The fund may invest in certain other funds managed by the investment adviser or its affiliates ("Central Funds") to more effectively invest in a diversified set of securities in a specific asset class such as money market instruments, bonds and other securities. Shares of Central Funds are only offered for purchase to the fund's investment adviser and its affiliates and other funds, investment vehicles and accounts managed by the fund's investment adviser and its affiliates. Central Funds do not charge management fees. As a result, the fund does not bear additional management fees when investing in Central Funds, but the fund does bear its proportionate share of Central Fund expenses. The investment results of the portions of the fund's assets invested in the Central Funds will be based upon the investment results of the Central Funds.

The fund may also lend portfolio securities to brokers, dealers and other institutions that provide cash or U.S. Treasury securities as collateral in an amount at least equal to the value of the securities loaned.

Prior to May 1, 2026, the fund was called Global Small Capitalization Fund.

The fund relies on the professional judgment of its investment adviser to make decisions about the fund's portfolio investments. The basic investment philosophy of the investment adviser is to seek to invest in attractively valued companies that, in its opinion, represent good, long-term investment opportunities. The investment adviser believes that an important way to accomplish this is through fundamental analysis, which may include meeting with company executives and employees, suppliers, customers and competitors. Securities may be sold when the investment adviser believes that they no longer represent relatively attractive investment opportunities.

The investment adviser may consider environmental, social and governance ("ESG") factors that, depending on the facts and circumstances, are material to the value of an issuer or instrument. ESG factors may include, but are not limited to, environmental issues (e.g., water use, emission levels, waste, environmental remediation), social issues (e.g., human capital, health and safety, changing customer behavior) or governance issues (e.g., board composition, executive compensation, shareholder dilution).

The following are principal risks associated with investing in the fund.

*Market conditions* — The prices of, and the income generated by, the securities held by the fund may decline – sometimes rapidly or unpredictably – due to various factors, including events or conditions affecting the general economy or particular industries or companies; overall market changes; local, regional or global political, social or economic instability; governmental, governmental agency or central bank responses to economic conditions; levels of public debt and deficits; changes in inflation rates; and currency exchange rate, interest rate and commodity price fluctuations.

Economies and financial markets throughout the world are highly interconnected. Economic, financial or political events, trading and tariff arrangements, wars, terrorism, cybersecurity events, natural disasters, public health emergencies (such as the spread of infectious disease), bank failures and other circumstances in one country or region, including actions taken by governmental or quasi-governmental authorities in response to any of the foregoing, could have impacts on global economies or markets. As a result, whether or not the fund invests in securities of issuers located in or with significant exposure to the countries affected, the value and liquidity of the fund's investments may be negatively affected by developments in other countries and regions.

*Issuer risks* — The prices of, and the income generated by, securities held by the fund may decline in response to various factors directly related to the issuers of such securities, including reduced demand for an issuer's goods or services, poor management performance, major litigation, investigations or other controversies related to the issuer, changes in the issuer's financial condition or credit rating, changes in government regulations affecting the issuer or its competitive environment and strategic initiatives such as mergers, acquisitions or dispositions and the market response to any such initiatives. An individual security may also be affected by factors relating to the industry or sector of the issuer or the securities markets as a whole, and conversely an industry or sector or the securities markets

American Funds Insurance Series / Prospectus&nbsp;&nbsp;&nbsp;&nbsp; 8

------

may be affected by a change in financial condition or other event affecting a single issuer. To the extent that the market prices of securities of issuers in the same or related industries or sectors tend to move in the same direction at the same time, and these issuers make up a sizeable portion of the market, events affecting one issuer, industry or sector or the securities markets generally may have a larger impact. If such issuers represent a substantial portion of major market indices, or the economy, a downturn in the prices of their securities may have a disproportionate adverse effect on the overall market, even if other segments of the market perform well. The fund's portfolio managers invest in issuers based on their level of investment conviction. At times, the fund may invest more significantly in a single issuer, which could increase the fund's volatility and the risk of loss arising from the factors described above.

*Investing in growth-oriented stocks* — Growth-oriented common stocks and other equity-type securities (such as preferred stocks, convertible preferred stocks and convertible bonds) may involve larger price swings and greater potential for loss than other types of investments. These risks may be even greater in the case of smaller capitalization stocks.

*Investing in small companies* — Investing in smaller companies may pose additional risks. For example, it is often more difficult to value or dispose of small company stocks and more difficult to obtain information about smaller companies than about larger companies. Furthermore, smaller companies often have limited product lines, operating histories, markets and/or financial resources, may be dependent on one or a few key persons for management, and can be more susceptible to losses. Moreover, the prices of their stocks may be more volatile than stocks of larger, more established companies, particularly during times of market turmoil.

*Investing outside the United States* — Securities of issuers domiciled outside the United States or with significant operations or revenues outside the United States, and securities tied economically to countries outside the United States, may lose value because of adverse political, social, economic or market developments (including social instability, regional conflicts, terrorism and war) in the countries or regions in which the issuers are domiciled, operate or generate revenue or to which the securities are tied economically. These securities may also lose value due to changes in foreign currency exchange rates against the U.S. dollar and/or currencies of other countries. Issuers of these securities may be more susceptible to actions of foreign governments, such as nationalization, currency blockage or the imposition of price controls, sanctions, or punitive taxes, each of which could adversely impact the value of these securities. Securities markets in certain countries may be more volatile and/or less liquid than those in the United States. Investments outside the United States may also be subject to different regulatory, legal, accounting, auditing, financial reporting and recordkeeping requirements, and may be more difficult to value, than those in the United States. In addition, the value of investments outside the United States may be reduced by foreign taxes, including foreign withholding taxes on interest and dividends. Further, there may be increased risks of delayed settlement of securities purchased or sold by the fund, which could impact the liquidity of the fund's portfolio. The risks of investing outside the United States may be heightened in connection with investments in emerging markets.

*Investing in emerging markets* — Investing in emerging markets may involve risks in addition to and greater than those generally associated with investing in the securities markets of developed countries. For instance, emerging market countries tend to have less developed political, economic and legal systems than those in developed countries. Accordingly, the governments of these countries may be less stable and more likely to intervene in the market economy, for example, by imposing capital controls, nationalizing a company or industry, placing restrictions on foreign ownership and on withdrawing sale proceeds of securities from the country, and/or imposing punitive taxes that could adversely affect the prices of securities. Information regarding issuers in emerging markets may be limited, incomplete or inaccurate, and such issuers may not be subject to regulatory, accounting, auditing, and financial reporting and recordkeeping standards comparable to those to which issuers in more developed markets are subject. The fund's rights with respect to its investments in emerging markets, if any, will generally be governed by local law, which may make it difficult or impossible for the fund to pursue legal remedies or to obtain and enforce judgments in local courts. In addition, the economies of these countries may be dependent on relatively few industries, may have limited access to capital and may be more susceptible to changes in local and global trade conditions and downturns in the world economy. Securities markets in these countries can also be relatively small and have substantially lower trading volumes. As a result, securities issued in these countries may be more volatile and less liquid, more vulnerable to market manipulation, and more difficult to value, than securities issued in countries with more developed economies and/or markets. Less certainty with respect to security valuations may lead to additional challenges and risks in calculating the fund's net asset value. Additionally, emerging markets are more likely to experience problems with the clearing and settling of trades and the holding of securities by banks, agents and depositories that are less established than those in developed countries.

*Liquidity risk* — Certain fund holdings may be or may become difficult or impossible to sell, particularly during times of market turmoil. Liquidity may be impacted by the lack of an active market for a holding, legal or contractual restrictions on resale, or the reduced number and capacity of market participants to make a market in such holding. Market prices for less liquid or illiquid holdings may be volatile or difficult to determine, and reduced liquidity may have an adverse impact on the market price of such holdings. Additionally, the sale of less liquid or illiquid holdings may involve substantial delays (including delays in settlement) and additional costs and the fund may be unable to sell such holdings when necessary to meet its liquidity needs or to try to limit losses, or may be forced to sell at a loss.

*Management* — The investment adviser to the fund actively manages the fund's investments. Consequently, the fund is subject to the risk that the methods and analyses, including models, tools and data, employed by the investment adviser in this process may be flawed or incorrect and may not produce the desired results. This could cause the fund to lose value or its investment results to lag relevant benchmarks or other funds with similar objectives.

The following are additional risks associated with investing in the fund.

*Exposure to country, region, industry or sector* — Subject to the fund's investment limitations, the fund may have significant exposure to a particular country, region, industry or sector. Such exposure may cause the fund to be more impacted by risks relating to and developments affecting the country, region, industry or sector, and thus its net asset value may be more volatile, than a fund without such

9&nbsp;&nbsp;&nbsp;&nbsp; American Funds Insurance Series / Prospectus

------

levels of exposure. For example, if the fund has significant exposure in a particular country, then social, economic, regulatory or other issues that negatively affect that country may have a greater impact on the fund than on a fund that is more geographically diversified.

*Lending of portfolio securities —* Securities lending involves risks, including the risk that the loaned securities may not be returned in a timely manner or at all, which would interfere with the fund's ability to vote proxies or settle transactions, and/or the risk of a counterparty default. Additionally, the fund may lose money from the reinvestment of collateral received on loaned securities in investments that decline in value, default or do not perform as expected.

*Cybersecurity breaches* — The fund may be subject to operational and information security risks through breaches in cybersecurity. Cybersecurity breaches can result from deliberate attacks or unintentional events, including "ransomware" attacks, the injection of computer viruses or malicious software code, the use of vulnerabilities in code to gain unauthorized access to digital information systems, networks or devices, or external attacks such as denial-of-service attacks on the investment adviser's or an affiliate's website that could render the fund's network services unavailable to intended end-users. These breaches may, among other things, lead to the unauthorized release of confidential information, misuse of the fund's assets or sensitive information, the disruption of the fund's operational capacity, the inability of fund shareholders to transact business, or the destruction of the fund's physical infrastructure, equipment or operating systems. These events could cause the fund to violate applicable privacy and other laws and could subject the fund to reputational damage, additional costs associated with corrective measures and/or financial loss. The fund may also be subject to additional risks if its third-party service providers, such as the fund's investment adviser, transfer agent, custodian, administrators and other financial intermediaries, experience similar cybersecurity breaches and potential outcomes. Cybersecurity risks may also impact issuers of securities in which the fund invests, which may cause the fund's investments in such issuers to lose value.

*Large shareholder transactions risk* — The fund may experience adverse effects when shareholders, including other funds or accounts advised by the investment adviser, purchase or redeem, individually or in the aggregate, large amounts of shares relative to the size of the fund. For example, when the investment adviser changes allocations in other funds and accounts it manages, such changes may result in shareholder transactions in the fund that are large relative to the size of the fund. Such large shareholder redemptions may cause the fund to sell portfolio securities at times when it would not otherwise do so, which may negatively impact the fund's net asset value and liquidity. Similarly, large fund share purchases may adversely affect the fund's performance to the extent that the fund is delayed in investing new cash and is required to maintain a larger cash position than it ordinarily would. These transactions may also accelerate the realization of taxable income to shareholders if such sales of investments resulted in gains, and may also increase transaction costs. In addition, a large redemption could result in the fund's current expenses being allocated over a smaller asset base, leading to an increase in the fund's expense ratio. These risks are heightened when the fund is small.

In addition to the principal investment strategies described above, the fund has other investment practices that are described in the statement of additional information, which includes a description of other risks related to the fund's principal investment strategies and other investment practices. The fund's investment results will depend on the ability of the fund's investment adviser to navigate the risks discussed above as well as those described in the statement of additional information.

**Fund comparative indexes** — The MSCI ACWI IMI Index is a free float-adjusted market capitalization-weighted index that is designed to measure the equity market results of large, mid, and small capitalization companies in both developed and emerging markets. The index consists of more than 40 developed and emerging market country indexes. Results reflect dividends net of withholding taxes. This index is unmanaged, and its results include reinvested dividends and/or distributions but do not reflect the effect of sales charges, commissions, account fees, expenses or U.S. federal income taxes.The MSCI All Country World Small Cap Index is a free float-adjusted market capitalization-weighted index that is designed to measure equity market results of smaller capitalization companies in both developed and emerging markets. Results reflect dividends net of withholding taxes. This index is unmanaged, and its results include reinvested dividends and/or distributions but do not reflect the effect of sales charges, commissions, account fees, expenses or U.S. federal income taxes.

**Portfolio holdings** A description of the fund's policies and procedures regarding disclosure of information about its portfolio holdings is available in the statement of additional information.

**EUPAC Fund** The fund's investment objective is to provide you with long-term growth of capital. While it has no present intention to do so, the fund's board may change the fund's investment objective without shareholder approval upon 60 days' written notice to shareholders.

The fund is designed for investors seeking capital appreciation and diversification through investments in common stocks and other equity-type securities (including depositary receipts), consistent with the fund's investment objective.

Investors in the fund should have a long-term perspective and be able to tolerate potentially sharp declines in value.

The following describes certain strategies that the investment adviser uses in pursuit of the fund's investment objective and the corresponding risks:

The fund invests primarily in common stocks in Europe and the Pacific Basin that the investment adviser believes have the potential for growth. Growth stocks are stocks that the investment adviser believes have the potential for above-average capital appreciation.

Normally, the fund will invest at least 80% of its net assets in securities of issuers in Europe and the Pacific Basin. This policy is subject to change only upon 60 days' notice to shareholders. A country will be considered part of Europe if it is part of the MSCI European indexes, and part of the Pacific Basin if any of its borders touches the Pacific Ocean. In determining the domicile of an issuer, the fund's investment adviser will generally look to the determination of MSCI Inc. (MSCI) for equity securities and Bloomberg for debt securities. In certain limited circumstances (including where relevant data is unavailable or the nature of a holding warrants special considerations), the adviser may also take into account additional factors, as applicable, including where the issuer's securities are listed; where the issuer is legally

organized, maintains principal corporate offices, conducts its principal operations, generates revenues and/or has credit risk exposure; and the source of guarantees, if any, of such securities. The fund may invest a portion of its assets in common stocks and other securities of companies in emerging markets.

The fund may also hold cash, cash equivalents and fixed-income securities, including commercial paper and short-term securities issued by the U.S. government, its agencies and instrumentalities. The percentage of the fund invested in such holdings varies and depends on various factors, including market conditions and purchases and redemptions of fund shares. The investment adviser may determine that it is appropriate to invest a substantial portion of the fund's assets in such instruments in response to certain circumstances, such as periods of market turmoil. For temporary defensive purposes, the fund may invest without limitation in such instruments. A larger percentage of such holdings could moderate the fund's investment results in a period of rising market prices. Alternatively, a larger percentage of such holdings could reduce the magnitude of the fund's loss in a period of falling market prices and provide liquidity to make additional investments or to meet redemptions.

The fund may invest in certain other funds managed by the investment adviser or its affiliates ("Central Funds") to more effectively invest in a diversified set of securities in a specific asset class such as money market instruments, bonds and other securities. Shares of Central Funds are only offered for purchase to the fund's investment adviser and its affiliates and other funds, investment vehicles and accounts managed by the fund's investment adviser and its affiliates. Central Funds do not charge management fees. As a result, the fund does not bear additional management fees when investing in Central Funds, but the fund does bear its proportionate share of Central Fund expenses. The investment results of the portions of the fund's assets invested in the Central Funds will be based upon the investment results of the Central Funds.

The fund may also lend portfolio securities to brokers, dealers and other institutions that provide cash or U.S. Treasury securities as collateral in an amount at least equal to the value of the securities loaned.

Prior to May 1, 2026, the fund was called International Fund.

The fund relies on the professional judgment of its investment adviser to make decisions about the fund's portfolio investments. The basic investment philosophy of the investment adviser is to seek to invest in attractively valued companies that, in its opinion, represent good, long-term investment opportunities. The investment adviser believes that an important way to accomplish this is through fundamental analysis, which may include meeting with company executives and employees, suppliers, customers and competitors. Securities may be sold when the investment adviser believes that they no longer represent relatively attractive investment opportunities.

The investment adviser may consider environmental, social and governance ("ESG") factors that, depending on the facts and circumstances, are material to the value of an issuer or instrument. ESG factors may include, but are not limited to, environmental issues (e.g., water use, emission levels, waste, environmental remediation), social issues (e.g., human capital, health and safety, changing customer behavior) or governance issues (e.g., board composition, executive compensation, shareholder dilution).

The following are principal risks associated with investing in the fund.

*Market conditions* — The prices of, and the income generated by, the common stocks and other securities held by the fund may decline – sometimes rapidly or unpredictably – due to various factors, including events or conditions affecting the general economy or particular industries or companies; overall market changes; local, regional or global political, social or economic instability; governmental, governmental agency or central bank responses to economic conditions; levels of public debt and deficits; changes in inflation rates; and currency exchange rate, interest rate and commodity price fluctuations.

Economies and financial markets throughout the world are highly interconnected. Economic, financial or political events, trading and tariff arrangements, wars, terrorism, cybersecurity events, natural disasters, public health emergencies (such as the spread of infectious disease), bank failures and other circumstances in one country or region, including actions taken by governmental or quasi-governmental authorities in response to any of the foregoing, could have impacts on global economies or markets. As a result, whether or not the fund invests in securities of issuers located in or with significant exposure to the countries affected, the value and liquidity of the fund's investments may be negatively affected by developments in other countries and regions.

*Issuer risks* — The prices of, and the income generated by, securities held by the fund may decline in response to various factors directly related to the issuers of such securities, including reduced demand for an issuer's goods or services, poor management performance, major litigation, investigations or other controversies related to the issuer, changes in the issuer's financial condition or credit rating, changes in government regulations affecting the issuer or its competitive environment and strategic initiatives such as mergers, acquisitions or dispositions and the market response to any such initiatives. An individual security may also be affected by factors relating to the industry or sector of the issuer or the securities markets as a whole, and conversely an industry or sector or the securities markets may be affected by a change in financial condition or other event affecting a single issuer. To the extent that the market prices of securities of issuers in the same or related industries or sectors tend to move in the same direction at the same time, and these issuers make up a sizeable portion of the market, events affecting one issuer, industry or sector or the securities markets generally may have a larger impact. If such issuers represent a substantial portion of major market indices, or the economy, a downturn in the prices of their securities may have a disproportionate adverse effect on the overall market, even if other segments of the market perform well. The fund's portfolio managers invest in issuers based on their level of investment conviction. At times, the fund may invest more significantly in a single issuer, which could increase the fund's volatility and the risk of loss arising from the factors described above.

*Investing in growth-oriented stocks* — Growth-oriented common stocks and other equity-type securities (such as preferred stocks, convertible preferred stocks and convertible bonds) may involve larger price swings and greater potential for loss than other types of investments. These risks may be even greater in the case of smaller capitalization stocks.

*Investing outside the United States* — Securities of issuers domiciled outside the United States or with significant operations or revenues outside the United States, and securities tied economically to countries outside the United States, may lose value because of adverse

11&nbsp;&nbsp;&nbsp;&nbsp; American Funds Insurance Series / Prospectus

------

political, social, economic or market developments (including social instability, regional conflicts, terrorism and war) in the countries or regions in which the issuers are domiciled, operate or generate revenue or to which the securities are tied economically. These securities may also lose value due to changes in foreign currency exchange rates against the U.S. dollar and/or currencies of other countries. Issuers of these securities may be more susceptible to actions of foreign governments, such as nationalization, currency blockage or the imposition of price controls, sanctions, or punitive taxes, each of which could adversely impact the value of these securities. Securities markets in certain countries may be more volatile and/or less liquid than those in the United States. Investments outside the United States may also be subject to different regulatory, legal, accounting, auditing, financial reporting and recordkeeping requirements, and may be more difficult to value, than those in the United States. In addition, the value of investments outside the United States may be reduced by foreign taxes, including foreign withholding taxes on interest and dividends. Further, there may be increased risks of delayed settlement of securities purchased or sold by the fund, which could impact the liquidity of the fund's portfolio. The risks of investing outside the United States may be heightened in connection with investments in emerging markets.

*Investing in emerging markets* — Investing in emerging markets may involve risks in addition to and greater than those generally associated with investing in the securities markets of developed countries. For instance, emerging market countries tend to have less developed political, economic and legal systems than those in developed countries. Accordingly, the governments of these countries may be less stable and more likely to intervene in the market economy, for example, by imposing capital controls, nationalizing a company or industry, placing restrictions on foreign ownership and on withdrawing sale proceeds of securities from the country, and/or imposing punitive taxes that could adversely affect the prices of securities. Information regarding issuers in emerging markets may be limited, incomplete or inaccurate, and such issuers may not be subject to regulatory, accounting, auditing, and financial reporting and recordkeeping standards comparable to those to which issuers in more developed markets are subject. The fund's rights with respect to its investments in emerging markets, if any, will generally be governed by local law, which may make it difficult or impossible for the fund to pursue legal remedies or to obtain and enforce judgments in local courts. In addition, the economies of these countries may be dependent on relatively few industries, may have limited access to capital and may be more susceptible to changes in local and global trade conditions and downturns in the world economy. Securities markets in these countries can also be relatively small and have substantially lower trading volumes. As a result, securities issued in these countries may be more volatile and less liquid, more vulnerable to market manipulation, and more difficult to value, than securities issued in countries with more developed economies and/or markets. Less certainty with respect to security valuations may lead to additional challenges and risks in calculating the fund's net asset value. Additionally, emerging markets are more likely to experience problems with the clearing and settling of trades and the holding of securities by banks, agents and depositories that are less established than those in developed countries.

*Management* — The investment adviser to the fund actively manages the fund's investments. Consequently, the fund is subject to the risk that the methods and analyses, including models, tools and data, employed by the investment adviser in this process may be flawed or incorrect and may not produce the desired results. This could cause the fund to lose value or its investment results to lag relevant benchmarks or other funds with similar objectives.

The following are additional risks associated with investing in the fund.

*Exposure to country, region, industry or sector* — Subject to the fund's investment limitations, the fund may have significant exposure to a particular country, region, industry or sector. Such exposure may cause the fund to be more impacted by risks relating to and developments affecting the country, region, industry or sector, and thus its net asset value may be more volatile, than a fund without such levels of exposure. For example, if the fund has significant exposure in a particular country, then social, economic, regulatory or other issues that negatively affect that country may have a greater impact on the fund than on a fund that is more geographically diversified.

*Investing in depositary receipts* — Depositary receipts are securities that evidence ownership interests in, and represent the right to receive, a security or a pool of securities that have been deposited with a bank or trust depository. Such securities may be less liquid or may trade at a lower price than the underlying securities of the issuer. Additionally, receipt of corporate information about the underlying issuer and proxy disclosure may not be timely and there may not be a correlation between such information and the market value of the depositary receipts.

*Liquidity risk* — Certain fund holdings may be or may become difficult or impossible to sell, particularly during times of market turmoil. Liquidity may be impacted by the lack of an active market for a holding, legal or contractual restrictions on resale, or the reduced number and capacity of market participants to make a market in such holding. Market prices for less liquid or illiquid holdings may be volatile or difficult to determine, and reduced liquidity may have an adverse impact on the market price of such holdings. Additionally, the sale of less liquid or illiquid holdings may involve substantial delays (including delays in settlement) and additional costs and the fund may be unable to sell such holdings when necessary to meet its liquidity needs or to try to limit losses, or may be forced to sell at a loss.

*Lending of portfolio securities —* Securities lending involves risks, including the risk that the loaned securities may not be returned in a timely manner or at all, which would interfere with the fund's ability to vote proxies or settle transactions, and/or the risk of a counterparty default. Additionally, the fund may lose money from the reinvestment of collateral received on loaned securities in investments that decline in value, default or do not perform as expected.

*Cybersecurity breaches* — The fund may be subject to operational and information security risks through breaches in cybersecurity. Cybersecurity breaches can result from deliberate attacks or unintentional events, including "ransomware" attacks, the injection of computer viruses or malicious software code, the use of vulnerabilities in code to gain unauthorized access to digital information systems, networks or devices, or external attacks such as denial-of-service attacks on the investment adviser's or an affiliate's website that could render the fund's network services unavailable to intended end-users. These breaches may, among other things, lead to the unauthorized release of confidential information, misuse of the fund's assets or sensitive information, the disruption of the fund's operational capacity, the inability of fund shareholders to transact business, or the destruction of the fund's physical infrastructure, equipment or operating

systems. These events could cause the fund to violate applicable privacy and other laws and could subject the fund to reputational damage, additional costs associated with corrective measures and/or financial loss. The fund may also be subject to additional risks if its third-party service providers, such as the fund's investment adviser, transfer agent, custodian, administrators and other financial intermediaries, experience similar cybersecurity breaches and potential outcomes. Cybersecurity risks may also impact issuers of securities in which the fund invests, which may cause the fund's investments in such issuers to lose value.

*Large shareholder transactions risk* — The fund may experience adverse effects when shareholders, including other funds or accounts advised by the investment adviser, purchase or redeem, individually or in the aggregate, large amounts of shares relative to the size of the fund. For example, when the investment adviser changes allocations in other funds and accounts it manages, such changes may result in shareholder transactions in the fund that are large relative to the size of the fund. Such large shareholder redemptions may cause the fund to sell portfolio securities at times when it would not otherwise do so, which may negatively impact the fund's net asset value and liquidity. Similarly, large fund share purchases may adversely affect the fund's performance to the extent that the fund is delayed in investing new cash and is required to maintain a larger cash position than it ordinarily would. These transactions may also accelerate the realization of taxable income to shareholders if such sales of investments resulted in gains, and may also increase transaction costs. In addition, a large redemption could result in the fund's current expenses being allocated over a smaller asset base, leading to an increase in the fund's expense ratio.

**Management and organization**

**Investment adviser** Capital Research and Management Company, an experienced investment management organization founded in 1931, serves as the investment adviser to the Series and other funds, including the American Funds. Capital Research and Management Company is a wholly owned subsidiary of The Capital Group Companies, Inc. and is located at 333 South Hope Street, Los Angeles, California 90071. Capital Research and Management Company manages the investment portfolios and business affairs of the Series. The total management fee paid by each fund to its investment adviser for the most recent fiscal year, including any amounts waived, in each case expressed as a percentage of average net assets of that fund, appears in the Annual Fund Operating Expenses table for each fund. Please see the statement of additional information for further details. A discussion regarding the basis for the approval of the Series' Investment Advisory and Service Agreement by the Series' board of trustees is contained in the Series' annual or semi-annual report in Form N-CSR for the most recent fiscal period.

Capital Research and Management Company manages equity assets through three equity investment divisions and fixed income assets through its fixed income investment division, Capital Fixed Income Investors. The three equity investment divisions — Capital International Investors, Capital Research Global Investors and Capital World Investors — make investment decisions independently of one another.

The equity investment divisions may, in the future, be incorporated as wholly owned subsidiaries of Capital Research and Management Company. In that event, Capital Research and Management Company would continue to be the investment adviser, and day-to-day investment management of equity assets would continue to be carried out through one or more of these subsidiaries. Although not currently contemplated, Capital Research and Management Company could incorporate its fixed income investment division in the future and engage it to provide day-to-day investment management of fixed income assets. Capital Research and Management Company and each of the funds it advises have received an exemptive order from the U.S. Securities and Exchange Commission that allows Capital Research and Management Company to use, upon approval of the funds' boards, its management subsidiaries and affiliates to provide day-to-day investment management services to the funds, including making changes to the management subsidiaries and affiliates providing such services. The Series' shareholders approved this arrangement; however, there is no assurance that Capital Research and Management Company will incorporate its investment divisions or exercise any authority granted to it under the exemptive order.

In addition, shareholders of the Series have approved a proposal to reorganize the Series into a Delaware statutory trust. However, the Series reserved the right to delay implementing the reorganization and has elected to do so.

**The Capital System<sup>TM</sup>** Capital Research and Management Company uses a system of multiple portfolio managers in managing fund assets. Under this approach, the portfolio of a fund is divided into segments managed by individual managers. In addition, Capital Research and Management Company's investment analysts may make investment decisions with respect to a portion of each underlying fund's portfolio. Investment decisions are subject to a fund's objective(s), policies and restrictions and the oversight of the appropriate investment-related committees of Capital Research and Management Company and its investment divisions.

Certain senior members of Capital Fixed Income Investors, the investment adviser's fixed income investment division, serve on the Portfolio Strategy Group. The group utilizes a research-driven process with input from the investment adviser's analysts, portfolio managers and economists to define investment themes on a range of macroeconomic factors, including duration, yield curve and sector allocation. Where applicable, the investment decisions made by a fund's fixed income portfolio managers are informed by the investment themes discussed by the group.

Information regarding the portfolio managers' compensation, their ownership of securities in the Series and other accounts they manage is in the statement of additional information.

**Purchases and redemptions of shares** Shares of the Series are currently offered only to insurance company separate accounts as well as so-called "feeder funds" under master-feeder arrangements sponsored by insurance companies as underlying investments for such insurance companies' variable annuity contracts and variable life insurance policies. All such shares may be purchased or redeemed by the insurance company separate accounts (or feeder funds) at net asset value without any sales or redemption charges. These purchases and redemptions are made at the price next determined after such purchases and redemptions of units of the separate accounts (or feeder funds). The Series typically expects to remit redemption proceeds one business day following receipt and acceptance of a redemption order, regardless of the method the Series uses to make such payment (e.g., check, wire or automated clearing house transfer). However, payment may take longer than one business day and may take up to seven days as generally permitted by the Investment Company Act of 1940, as amended (the "1940 Act"). Under the 1940 Act, the Series may be permitted to pay redemption proceeds beyond seven days under certain limited circumstances.

Under normal conditions, the Series typically expects to meet shareholder redemptions from a reserve of highly liquid assets, such as cash or cash equivalents. The Series may use additional methods to meet shareholder redemptions, if they become necessary. These methods may include, but are not limited to, the sale of portfolio assets, the use of overdraft protection afforded by the Series' custodian bank, borrowing from a line of credit and making payment with fund securities or other fund assets rather than in cash (as further discussed in the following paragraph).

Although payment of redemptions normally will be in cash, the Series may pay the redemption price wholly or partly with portfolio securities or other fund assets under conditions and circumstances determined by the Series' board of trustees. On the same redemption date, some shareholders may be paid in whole or in part in securities (which may differ among those shareholders), while other shareholders may be paid entirely in cash. In general, in-kind redemptions to affiliated shareholders will as closely as practicable represent the affiliated shareholder's pro rata share of the Series' securities, subject to certain exceptions. Securities distributed in-kind to unaffiliated shareholders will be selected by the investment adviser in a manner the investment adviser deems to be fair and reasonable to the Series' shareholders. The disposal of the securities received in-kind may be subject to brokerage costs and, until sold, such securities remain subject to market risk and liquidity risk, including the risk that such securities are or become difficult to sell. If the Series pays your redemption with illiquid or less liquid securities, you will bear the risk of not being able to sell such securities.

**Frequent trading of fund shares** The Series and Capital Client Group, Inc., the Series' distributor, reserve the right to reject any purchase order for any reason. The funds are not designed to serve as vehicles for frequent trading. Frequent trading of fund shares may lead to increased costs to the funds and less efficient management of the funds' portfolios, potentially resulting in dilution of the value of the shares held by long-term shareholders. Accordingly, purchases, including those that are part of exchange activity, that the Series or Capital Client Group, Inc. has determined could involve actual or potential harm to a fund may be rejected.

The Series, through its transfer agent, American Funds Service Company, has agreements with the Series' insurance relationships to maintain its surveillance procedures that are designed to detect frequent trading in fund shares. The agreements generally require the insurance companies to (i) provide, upon request from a fund, the Series or their agent, certain identifying and account information regarding contract owners who invest in fund shares through an insurance company account and (ii) execute instructions from a fund, the Series or their agent to restrict further purchases or exchanges of fund shares by a contract owner who the Series has identified as having engaged in potentially harmful market timing or frequent trading. Under these procedures, various analytics are used to evaluate factors that may be indicative of frequent trading. For example, transactions in fund shares that exceed certain monetary thresholds may be scrutinized. American Funds Service Company may work with the insurance company separate accounts or feeder funds to apply their procedures that American Funds Service Company believes are reasonably designed to enforce the frequent trading policies of the Series. You should refer to disclosures provided by the insurance company with which you have a contract to determine the specific trading restrictions that apply to you.

Under the Series' frequent trading policy, certain trading activity will not be treated as frequent trading, such as:

· retirement plan contributions, loans and distributions (including hardship withdrawals) identified as such on the retirement plan recordkeeper's system;

· purchases and redemptions in community foundation accounts;

· purchase transactions involving in-kind transfers of fund shares, if the entity maintaining the contract owner's account is able to identify the transaction as one of these types of transactions;

· transactions by certain intermediaries in accordance with established hedging programs approved by the fund's investment adviser; and

· systematic redemptions and purchases if the entity maintaining the contract owner's account is able to identify the transaction as a systematic redemption or purchase.

Generally, purchases and redemptions will not be considered "systematic" unless the transaction is prescheduled for a specific date.

American Funds Service Company will monitor for other types of activity that could potentially be harmful to the Series – for example short-term trading activity in multiple funds. If American Funds Service Company identifies any activity that may constitute frequent trading, it reserves the right to contact the insurance company separate account or feeder fund and request that the separate account or feeder fund either provide information regarding an account owner's transactions or restrict the account owner's trading. If American Funds Service Company is not satisfied that insurance company separate account or feeder fund has taken appropriate action, American Funds Service Company may terminate the separate account's or feeder fund's ability to transact in fund shares.

There is no guarantee that all instances of frequent trading in fund shares will be prevented.

**Notwithstanding the Series' surveillance procedures described above, all transactions in fund shares remain subject to the right of the Series, Capital Client Group, Inc. and American Funds Service Company to restrict potentially abusive trading generally, including the types of transactions described above that will not be prevented.**

**Valuing shares** The net asset value of each share class of a fund is the value of a single share of that class. Net asset value is computed by adding a class's share of the value of a fund's investments, cash and other assets, subtracting the class's share of the fund's liabilities allocated to the class, and dividing the result by the number of shares of that class that are outstanding. Realized investment income and gain is included in the fund's net asset value until the ex-dividend date, when the declared dividend amount is treated as a fund liability. The net asset value per share is calculated once daily as of the close of regular trading on the New York Stock Exchange, normally 4 p.m. New York time, each day the New York Stock Exchange is open. If the New York Stock Exchange makes a scheduled (e.g., the day after Thanksgiving) or an unscheduled close prior to 4 p.m. New York time, the net asset value of each fund will be determined at approximately the time the New York Stock Exchange closes on that day. If on such a day market quotations and prices from third-party pricing services are not based as of the time of the early close of the New York Stock Exchange but are as of a later time (up to approximately 4 p.m. New York time), for example because the market remains open after the close of the New York Stock Exchange, those later market quotations and prices will be used in determining the funds' net asset value.

Equity securities are valued primarily on the basis of market quotations, and debt securities are valued primarily on the basis of prices from third-party pricing services due to the lack of market quotations. Futures contracts are valued primarily on the basis of settlement prices. The funds' portfolio investments are valued in accordance with procedures for making fair value determinations if market quotations are not readily available, including procedures to determine the representativeness of third-party vendor prices, or in the event market quotations or third-party vendor prices are not considered reliable. For example, if events occur between the close of markets outside the United States and the close of regular trading on the New York Stock Exchange that, in the opinion of the investment adviser, materially affect the value of any of the funds' equity securities that trade principally in those international markets, those securities will be valued in accordance with fair value procedures. Similarly, fair value procedures will be employed if an issuer defaults on its debt securities and there is no market for its securities. Use of these procedures is intended to result in more appropriate net asset values and, where applicable, to reduce potential arbitrage opportunities otherwise available to short-term investors.

Because certain of the funds may hold securities that are listed primarily on foreign exchanges that trade on weekends or days when the funds do not price their shares, the values of securities held in the funds may change on days when you will not be able to purchase or redeem fund shares.

Shares of the funds will be purchased or sold at the net asset value next determined after receipt of requests from the appropriate insurance company. Requests received by the appropriate insurance company prior to 4 p.m. New York time and communicated by the insurance company to the Series or its agent will be purchased or sold at that day's net asset value. Orders in good order received after the New York Stock Exchange closes (scheduled or unscheduled) will be processed at the net asset value (plus any applicable sales charge) calculated on the following business day.

**Plan of distribution** The Series has adopted a plan of distribution or "12b-1 plan" for Class 2 shares. Under the plan, the Series may finance activities primarily intended to sell shares, provided the categories of expenses are approved in advance by the Series' board of trustees. The plan provides for annual expenses of .25% for Class 2 shares. Amounts paid under the 12b-1 plan are used by insurance company contract issuers to cover distribution expenses and/or the expenses of certain contract owner services. The 12b-1 fees paid by the Series, as a percentage of average net assets, for the most recent fiscal year, are indicated in the prospectus in the Annual Fund Operating Expenses table for each fund. Since these fees are paid out of the Series' assets on an ongoing basis, over time they may cost you more than paying other types of sales charges or service fees and reduce the return of an investment in Class 2 shares.

**Other compensation to dealers** Capital Client Group, Inc., at its expense, provides additional compensation to insurance companies. These payments may be made, at the discretion of Capital Client Group, Inc., to insurance companies (or their affiliates) that have sold shares of the funds of the American Funds Insurance Series and American Funds as the exclusive underlying investments to their variable annuity contracts. A number of factors will be considered in determining payments, including the sales, assets, and the quality of the insurance company's relationship with Capital Client Group, Inc. The payment will typically be determined using a formula applied consistently to insurance companies based on the relevant facts and circumstances. Aggregate payments made by Capital Client Group, Inc. to insurance companies may also change from year to year. Only assets and deposits in variable annuity contracts that offer exclusively shares of the funds of the American Funds Insurance Series and American Funds are included in the formula. Further, assets for which the insurance company, or an affiliated broker-dealer, acts as an ERISA investment fiduciary are generally excluded from the formula. Capital Client Group, Inc. makes these payments to help defray the costs incurred by qualifying insurance companies in connection with efforts to educate their sales force about the American Funds Insurance Series and American Funds so that they help financial advisers make recommendations and provide services that are suitable and meet contractholders' needs. These payments may also be made to help defray the costs associated with the insurance company's provision of account-related services and activities and support the insurance company's distribution activities. Capital Client Group, Inc. will, on a periodic basis, determine the advisability of continuing these payments. As of May 1, 2026, the insurance companies (or their affiliates) that Capital Client Group, Inc. anticipates will receive additional compensation based on prior payments include Lincoln National Life Insurance Co.

Firms receiving additional compensation payments must sign a letter acknowledging the purpose of the payment and Capital Client Group, Inc.'s goal that the payment will help facilitate education of their sales force about the American Funds Insurance Series and American Funds to help financial professionals make suitable recommendations and better serve their clients who invest in the funds as underlying investments to variable annuity contracts. The letters generally require the firms to (1) offers shares of the funds of the American Funds Insurance Series and American Funds as the exclusive underlying investments to their variable annuity contracts, and (2) provide Capital Client Group, Inc. broad access to their sales force and product platforms and develop a business plan to achieve such access.

Capital Client Group, Inc. may also pay expenses associated with meetings and other training and educational opportunities conducted by insurance companies, selling dealers, advisory platform providers and other intermediaries to facilitate educating financial professionals and shareholders about the American Funds Insurance Series and American Funds. For example, some of these expenses may include, but not be limited to, meeting sponsor fees, meeting location fees, fees for data and reporting, and fees to obtain lists of financial professionals to better tailor training and education opportunities. In addition, Capital Client Group, Inc. and/or its affiliates may make payments to third parties for platform fees and other services.

If investment advisers, distributors or other affiliates of mutual funds pay additional compensation or other incentives to insurance companies in differing amounts, insurance companies and the financial professionals with which they interact may have financial incentives for recommending a particular mutual fund over other mutual funds or investments, creating a potential conflict of interest. You should consult with your financial professional and review carefully any disclosure by your financial professional's firm as to compensation received.

**Fund expenses** In periods of market volatility, assets of the funds may decline significantly, causing total annual fund operating expenses (as a percentage of the value of your investment) to become higher than the numbers shown in the Annual Fund Operating Expenses tables in this prospectus.

The "Other expenses" items in the Annual Fund Operating Expenses tables in this prospectus are based on expenses as of each fund's most recently completed fiscal year. These items include third-party expenses, such as custodial, legal, audit, accounting, regulatory reporting and pricing vendor services, and an administrative services fee payable to the Series' investment adviser for administrative services provided by the Series' investment adviser and its affiliates.

For all share classes, "Other expenses" items in the Annual Fund Operating Expenses table in this prospectus include fees for administrative services provided by the fund's investment adviser and its affiliates. Administrative services are provided by the investment adviser and its affiliates to help assist third parties providing non-distribution services to fund shareholders. These services include providing in-depth information on the fund and market developments that impact fund investments. Administrative services also include, but are not limited to, coordinating, monitoring and overseeing third parties that provide services to fund shareholders.

The Administrative Services Agreement between the fund and the investment adviser provides the fund the ability to charge an administrative services fee of .05% for all share classes. The fund's investment adviser receives an administrative services fee at the annual rate of .03% of the average daily net assets of the fund attributable to all share classes (which could be increased as noted above) for its provision of administrative services.

**Investment results** All fund results in the "Investment results" section of this prospectus reflect the reinvestment of dividends and capital gains distributions, if any. Unless otherwise noted, fund results reflect any fee waivers and/or expense reimbursements in effect during the period presented.

**Distributions and taxes** Each fund of the Series intends to qualify as a "regulated investment company" under the Internal Revenue Code. In any fiscal year in which a fund so qualifies and distributes to shareholders its investment company taxable income and net realized capital gain, the fund itself is relieved of federal income tax.

It is the Series' policy to distribute to the shareholders (the insurance company separate accounts) all of its investment company taxable income and capital gain for each fiscal year.

**Financial highlights** The Financial Highlights table is intended to help you understand a fund's results for the past five fiscal years (or, if shorter, the period of operations). Certain information reflects financial results for a single share of a particular class. The total returns in the table represent the rate that an investor would have earned or lost on an investment in a fund (assuming reinvestment of all dividends and capital gain distributions). Where indicated, figures in the table reflect the impact, if any, of certain waivers from Capital Research and Management Company. For more information about these waivers, see the fund's statement of additional information and Form N-CSR. The information in the Financial Highlights table has been audited by PricewaterhouseCoopers LLP, whose current report, along with the funds' financial statements, is included in the statement of additional information, which is available upon request. Figures shown do not reflect insurance contract fees and expenses. If insurance contract fees and expenses were reflected, results would be lower.

**The U.S. Securities and Exchange Commission has not approved or disapproved of these securities. Further, it has not determined that this prospectus is accurate or complete. Any representation to the contrary is a criminal offense.**

 **EUPAC Fund** 

**Investment objective** The fund's investment objective is to provide you with long-term growth of capital.

**Fees and expenses of the fund** This table describes the fees and expenses that you may pay if you buy, hold and sell an interest in Class 3 shares of the fund. **You may pay other fees, such as insurance contract fees and expenses, which are not reflected in the tables and examples below.** If insurance contract fees and expenses were reflected, expenses shown would be higher.

---

| | |
|:---|:---|
| **Annual fund operating expenses (expenses that you pay each year as a percentage of the net asset value of your investment)** | Class 3 |
| Management fee | 0.48% |
| Distribution and/or service (12b-1) fees | 0.18 |
| Other expenses | 0.05 |
| Total annual fund operating expenses | 0.71 |
| Fee waiver\* | 0.06 |
| Total annual fund operating expenses after fee waiver | 0.65 |

---

\* The investment adviser is currently waiving a portion of its management fee equal to 0.06% of the fund's net assets. This waiver will be in effect through at least May 1, 2027. The waiver may only be modified or terminated with the approval of the fund's board.

**Example** This example is intended to help you compare the cost of investing in Class 3 shares of the fund with the cost of investing in other mutual funds.

The example assumes that you invest $10,000 in the fund for the time periods indicated and then redeem or hold all of your shares at the end of those periods. The example also assumes that your investment has a 5% return each year and that the fund's operating expenses remain the same. The example does not reflect insurance contract expenses. If insurance contract expenses were reflected, expenses shown would be higher. The example reflects the fee waiver described above through the expiration date of such waiver and total annual fund operating expenses thereafter. No sales charge (load) or other fees are charged by the fund upon redemption, so you would incur these hypothetical costs whether or not you were to redeem your shares at the end of the given period. Although your actual costs may be higher or lower, based on these assumptions your costs would be:

---

| | | | | |
|:---|:---|:---|:---|:---|
|  | 1 year | 3 years | 5 years | 10 years |
| Class 3 | $66 | $221 | $389 | $877 |

---

**Portfolio turnover** The fund pays transaction costs, such as commissions, when it buys and sells securities (or "turns over" its portfolio). A higher portfolio turnover rate may indicate higher transaction costs. These costs, which are not reflected in annual fund operating expenses or in the example, affect the fund's investment results. During the most recent fiscal year, the fund's portfolio turnover rate was 63% of the average value of its portfolio.

**Principal investment strategies** The fund invests primarily in common stocks in Europe and the Pacific Basin that the investment adviser believes have the potential for growth. Growth stocks are stocks that the investment adviser believes have the potential for above-average capital appreciation.

Normally the fund will invest at least 80% of its net assets in securities of issuers in Europe and the Pacific Basin. A country will be considered part of Europe if it is part of the MSCI European indexes, and part of the Pacific Basin if any of its borders touches the Pacific Ocean. In determining the domicile of an issuer, the fund's investment adviser will generally look to the determination of MSCI Inc. (MSCI) for equity securities and Bloomberg for debt securities. In certain limited circumstances (including where relevant data is unavailable or the nature of a holding warrants special considerations), the adviser may also take into account additional factors, as applicable, including where the issuer's securities are listed; where the issuer is legally organized, maintains principal corporate offices, conducts its principal operations, generates revenues and/or has credit risk exposure; and the source of guarantees, if any, of such securities. The fund may invest a portion of its assets in common stocks and other securities of companies in emerging markets.

Prior to May 1, 2026, the fund was called International Fund.

The investment adviser uses a system of multiple portfolio managers in managing the fund's assets. Under this approach, the portfolio of the fund is divided into segments managed by individual managers.

The fund relies on the professional judgment of its investment adviser to make decisions about the fund's portfolio investments. The basic investment philosophy of the investment adviser is to seek to invest in attractively valued companies that, in its opinion, represent good, long-term investment opportunities. Securities may be sold when the investment adviser believes that they no longer represent relatively attractive investment opportunities.

**Principal risks This section describes the principal risks associated with investing in the fund. You may lose money by investing in the fund. The likelihood of loss may be greater if you invest for a shorter period of time.** 

*Market conditions* — The prices of, and the income generated by, the common stocks and other securities held by the fund may decline – sometimes rapidly or unpredictably – due to various factors, including events or conditions affecting the general economy or particular industries or companies; overall market changes; local, regional or global political, social or economic instability; governmental, governmental agency or central bank responses to economic conditions; levels of public debt and deficits; changes in inflation rates; and currency exchange rate, interest rate and commodity price fluctuations.

Economies and financial markets throughout the world are highly interconnected. Economic, financial or political events, trading and tariff arrangements, wars, terrorism, cybersecurity events, natural disasters, public health emergencies (such as the spread of infectious disease), bank failures and other circumstances in one country or region, including actions taken by governmental or quasi-governmental authorities in response to any of the foregoing, could have impacts on global economies or markets. As a result, whether or not the fund invests in securities of issuers located in or with significant exposure to the countries affected, the value and liquidity of the fund's investments may be negatively affected by developments in other countries and regions.

*Issuer risks* — The prices of, and the income generated by, securities held by the fund may decline in response to various factors directly related to the issuers of such securities, including reduced demand for an issuer's goods or services, poor management performance, major litigation, investigations or other controversies related to the issuer, changes in the issuer's financial condition or credit rating, changes in government regulations affecting the issuer or its competitive environment and strategic initiatives such as mergers, acquisitions or dispositions and the market response to any such initiatives. An individual security may also be affected by factors relating to the industry or sector of the issuer or the securities markets as a whole, and conversely an industry or sector or the securities markets may be affected by a change in financial condition or other event affecting a single issuer.

*Investing in growth-oriented stocks* — Growth-oriented common stocks and other equity-type securities (such as preferred stocks, convertible preferred stocks and convertible bonds) may involve larger price swings and greater potential for loss than other types of investments. These risks may be even greater in the case of smaller capitalization stocks.

*Investing outside the United States* — Securities of issuers domiciled outside the United States or with significant operations or revenues outside the United States, and securities tied economically to countries outside the United States, may lose value because of adverse political, social, economic or market developments (including social instability, regional conflicts, terrorism and war) in the countries or regions in which the issuers are domiciled, operate or generate revenue or to which the securities are tied economically. These securities may also lose value due to changes in foreign currency exchange rates against the U.S. dollar and/or currencies of other countries. Issuers of these securities may be more susceptible to actions of foreign governments, such as nationalization, currency blockage or the imposition of price controls, sanctions, or punitive taxes, each of which could adversely impact the value of these securities. Securities markets in certain countries may be more volatile and/or less liquid than those in the United States. Investments outside the United States may also be subject to different regulatory, legal, accounting, auditing, financial reporting and recordkeeping requirements, and may be more difficult to value, than those in the United States. In addition, the value of investments outside the United States may be reduced by foreign taxes, including foreign withholding taxes on interest and dividends. Further, there may be increased risks of delayed settlement of securities purchased or sold by the fund, which could impact the liquidity of the fund's portfolio. The risks of investing outside the United States may be heightened in connection with investments in emerging markets.

*Investing in emerging markets* — Investing in emerging markets may involve risks in addition to and greater than those generally associated with investing in the securities markets of developed countries. For instance, emerging market countries tend to have less developed political, economic and legal systems than those in developed countries. Accordingly, the governments of these countries may be less stable and more likely to intervene in the market economy, for example, by imposing capital controls, nationalizing a company or industry, placing restrictions on foreign ownership and on withdrawing sale proceeds of securities from the country, and/or imposing punitive taxes that could adversely affect the prices of securities. Information regarding issuers in emerging markets may be limited, incomplete or inaccurate, and such issuers may not be subject to regulatory, accounting, auditing, and financial reporting and recordkeeping standards comparable to those to which issuers in more developed markets are subject. The fund's rights with respect to its investments in emerging markets, if any, will generally be governed by local law, which may make it difficult or impossible for the fund to pursue legal remedies or to obtain and enforce judgments in local courts. In addition, the economies of these countries may be dependent on relatively few industries, may have limited access to capital and may be more susceptible to changes in local and global trade conditions and downturns in the world economy. Securities markets in these countries can also be relatively small and have substantially lower trading volumes. As a result, securities issued in these countries may be more volatile and less liquid, more vulnerable to market manipulation, and more difficult to value, than securities issued in countries with more developed economies and/or markets. Less certainty with respect to security valuations may lead to additional challenges and risks in calculating the fund's net asset value. Additionally, emerging markets are more likely to experience problems with the clearing and settling of trades and the holding of securities by banks, agents and depositories that are less established than those in developed countries.

*Management* — The investment adviser to the fund actively manages the fund's investments. Consequently, the fund is subject to the risk that the methods and analyses, including models, tools and data, employed by the investment adviser in this process may be flawed or incorrect and may not produce the desired results. This could cause the fund to lose value or its investment results to lag relevant benchmarks or other funds with similar objectives.

Your investment in the fund is not a bank deposit and is not insured or guaranteed by the Federal Deposit Insurance Corporation or any other governmental agency, entity or person. You should consider how this fund fits into your overall investment program.

**Investment results** The following bar chart shows how the investment results of the Class 3 shares of the fund have varied from year to year, and the following table shows how the fund's average annual total returns for various periods compare with a broad measure of securities market results and, if applicable, other measures of market results that reflect the fund's investment universe. This information provides some indication of the risks of investing in the fund. Past investment results (before and after taxes) are not predictive of future investment results. Figures shown reflect fees and expenses associated with an investment in the fund, but do not reflect insurance contract fees and expenses. If insurance contract fees and expenses were included, results would have been lower. Updated information on the fund's investment results can be obtained by visiting capitalgroup.com/afis.

\*Lifetime returns are from May 1, 1990, the date the fund began investment operations. Class 3 shares began investment operations on January 16, 2004; therefore, returns for the fund prior to that date assume a hypothetical investment in Class 1 shares, but reflect the .18% annual expense that applies to Class 3 shares and is described in the "Plan of distribution" section of this prospectus. Returns for Class 1 shares are comparable to those of Class 3 shares because both classes invest in the same portfolio of securities.

**Purchase and sale of fund shares** Shares of the fund are not sold directly to the general public. The fund is offered only as an underlying investment option for variable insurance contracts, and insurance company separate accounts and qualified feeder funds — and not the holders of variable insurance contracts — are the shareholders of the fund. Although the fund does not require a minimum amount for initial or subsequent purchases from insurance companies, your insurance company may impose investment minimums for your purchase of the fund.

You may sell (redeem) shares on any business day. You must sell (redeem) shares through your insurance company.

**Tax information** See your variable insurance contract prospectus for information regarding the federal income tax treatment of your variable insurance contract and related distributions.

**Payments to broker-dealers and other financial intermediaries** The fund is not sold directly to the general public but instead is offered as an underlying investment option for variable insurance contracts. The fund and its related companies may make payments to the sponsoring insurance company (or its affiliates) for distribution and/or other services. These payments may be a factor that the insurance company considers in including the fund as an underlying investment option in the variable insurance contract. The prospectus (or other offering document) for your variable insurance contract may contain additional information about these payments.

**EUPAC Fund** The fund's investment objective is to provide you with long-term growth of capital. While it has no present intention to do so, the fund's board may change the fund's investment objective without shareholder approval upon 60 days' written notice to shareholders.

The fund is designed for investors seeking capital appreciation and diversification through investments in common stocks and other equity-type securities (including depositary receipts), consistent with the fund's investment objective.

Investors in the fund should have a long-term perspective and be able to tolerate potentially sharp declines in value.

The following describes certain strategies that the investment adviser uses in pursuit of the fund's investment objective and the corresponding risks:

The fund invests primarily in common stocks in Europe and the Pacific Basin that the investment adviser believes have the potential for growth. Growth stocks are stocks that the investment adviser believes have the potential for above-average capital appreciation.

Normally, the fund will invest at least 80% of its net assets in securities of issuers in Europe and the Pacific Basin. This policy is subject to change only upon 60 days' notice to shareholders. A country will be considered part of Europe if it is part of the MSCI European indexes, and part of the Pacific Basin if any of its borders touches the Pacific Ocean. In determining the domicile of an issuer, the fund's investment adviser will generally look to the determination of MSCI Inc. (MSCI) for equity securities and Bloomberg for debt securities. In certain limited circumstances (including where relevant data is unavailable or the nature of a holding warrants special considerations), the adviser may also take into account additional factors, as applicable, including where the issuer's securities are listed; where the issuer is legally organized, maintains principal corporate offices, conducts its principal operations, generates revenues and/or has credit risk exposure; and the source of guarantees, if any, of such securities. The fund may invest a portion of its assets in common stocks and other securities of companies in emerging markets.

The fund may also hold cash, cash equivalents and fixed-income securities, including commercial paper and short-term securities issued by the U.S. government, its agencies and instrumentalities. The percentage of the fund invested in such holdings varies and depends on various factors, including market conditions and purchases and redemptions of fund shares. The investment adviser may determine that it is appropriate to invest a substantial portion of the fund's assets in such instruments in response to certain circumstances, such as periods of market turmoil. For temporary defensive purposes, the fund may invest without limitation in such instruments. A larger percentage of such holdings could moderate the fund's investment results in a period of rising market prices. Alternatively, a larger percentage of such holdings could reduce the magnitude of the fund's loss in a period of falling market prices and provide liquidity to make additional investments or to meet redemptions.

The fund may invest in certain other funds managed by the investment adviser or its affiliates ("Central Funds") to more effectively invest in a diversified set of securities in a specific asset class such as money market instruments, bonds and other securities. Shares of Central Funds are only offered for purchase to the fund's investment adviser and its affiliates and other funds, investment vehicles and accounts managed by the fund's investment adviser and its affiliates. Central Funds do not charge management fees. As a result, the fund does not bear additional management fees when investing in Central Funds, but the fund does bear its proportionate share of Central Fund expenses. The investment results of the portions of the fund's assets invested in the Central Funds will be based upon the investment results of the Central Funds.

The fund may also lend portfolio securities to brokers, dealers and other institutions that provide cash or U.S. Treasury securities as collateral in an amount at least equal to the value of the securities loaned.

Prior to May 1, 2026, the fund was called International Fund.

The fund relies on the professional judgment of its investment adviser to make decisions about the fund's portfolio investments. The basic investment philosophy of the investment adviser is to seek to invest in attractively valued companies that, in its opinion, represent good, long-term investment opportunities. The investment adviser believes that an important way to accomplish this is through fundamental analysis, which may include meeting with company executives and employees, suppliers, customers and competitors. Securities may be sold when the investment adviser believes that they no longer represent relatively attractive investment opportunities.

The investment adviser may consider environmental, social and governance ("ESG") factors that, depending on the facts and circumstances, are material to the value of an issuer or instrument. ESG factors may include, but are not limited to, environmental issues (e.g., water use, emission levels, waste, environmental remediation), social issues (e.g., human capital, health and safety, changing customer behavior) or governance issues (e.g., board composition, executive compensation, shareholder dilution).

The following are principal risks associated with investing in the fund.

*Market conditions* — The prices of, and the income generated by, the common stocks and other securities held by the fund may decline – sometimes rapidly or unpredictably – due to various factors, including events or conditions affecting the general economy or particular industries or companies; overall market changes; local, regional or global political, social or economic instability; governmental, governmental agency or central bank responses to economic conditions; levels of public debt and deficits; changes in inflation rates; and currency exchange rate, interest rate and commodity price fluctuations.

Economies and financial markets throughout the world are highly interconnected. Economic, financial or political events, trading and tariff arrangements, wars, terrorism, cybersecurity events, natural disasters, public health emergencies (such as the spread of infectious disease), bank failures and other circumstances in one country or region, including actions taken by governmental or quasi-governmental authorities in response to any of the foregoing, could have impacts on global economies or markets. As a result, whether or not the fund invests in securities of issuers located in or with significant exposure to the countries affected, the value and liquidity of the fund's investments may be negatively affected by developments in other countries and regions.

*Issuer risks* — The prices of, and the income generated by, securities held by the fund may decline in response to various factors directly related to the issuers of such securities, including reduced demand for an issuer's goods or services, poor management performance, major litigation, investigations or other controversies related to the issuer, changes in the issuer's financial condition or credit rating, changes in government regulations affecting the issuer or its competitive environment and strategic initiatives such as mergers, acquisitions or dispositions and the market response to any such initiatives. An individual security may also be affected by factors relating to the industry or sector of the issuer or the securities markets as a whole, and conversely an industry or sector or the securities markets may be affected by a change in financial condition or other event affecting a single issuer. To the extent that the market prices of securities of issuers in the same or related industries or sectors tend to move in the same direction at the same time, and these issuers make up a sizeable portion of the market, events affecting one issuer, industry or sector or the securities markets generally may have a larger impact. If such issuers represent a substantial portion of major market indices, or the economy, a downturn in the prices of their securities may have a disproportionate adverse effect on the overall market, even if other segments of the market perform well. The fund's portfolio managers invest in issuers based on their level of investment conviction. At times, the fund may invest more significantly in a single issuer, which could increase the fund's volatility and the risk of loss arising from the factors described above.

*Investing in growth-oriented stocks* — Growth-oriented common stocks and other equity-type securities (such as preferred stocks, convertible preferred stocks and convertible bonds) may involve larger price swings and greater potential for loss than other types of investments. These risks may be even greater in the case of smaller capitalization stocks.

*Investing outside the United States* — Securities of issuers domiciled outside the United States or with significant operations or revenues outside the United States, and securities tied economically to countries outside the United States, may lose value because of adverse political, social, economic or market developments (including social instability, regional conflicts, terrorism and war) in the countries or regions in which the issuers are domiciled, operate or generate revenue or to which the securities are tied economically. These securities may also lose value due to changes in foreign currency exchange rates against the U.S. dollar and/or currencies of other countries. Issuers of these securities may be more susceptible to actions of foreign governments, such as nationalization, currency blockage or the imposition of price controls, sanctions, or punitive taxes, each of which could adversely impact the value of these securities. Securities markets in certain countries may be more volatile and/or less liquid than those in the United States. Investments outside the United States may also be subject to different regulatory, legal, accounting, auditing, financial reporting and recordkeeping requirements, and may be more difficult to value, than those in the United States. In addition, the value of investments outside the United States may be reduced by foreign taxes, including foreign withholding taxes on interest and dividends. Further, there may be increased risks of delayed settlement of securities purchased or sold by the fund, which could impact the liquidity of the fund's portfolio. The risks of investing outside the United States may be heightened in connection with investments in emerging markets.

*Investing in emerging markets* — Investing in emerging markets may involve risks in addition to and greater than those generally associated with investing in the securities markets of developed countries. For instance, emerging market countries tend to have less developed political, economic and legal systems than those in developed countries. Accordingly, the governments of these countries may be less stable and more likely to intervene in the market economy, for example, by imposing capital controls, nationalizing a company or industry, placing restrictions on foreign ownership and on withdrawing sale proceeds of securities from the country, and/or imposing punitive taxes that could adversely affect the prices of securities. Information regarding issuers in emerging markets may be limited, incomplete or inaccurate, and such issuers may not be subject to regulatory, accounting, auditing, and financial reporting and recordkeeping standards comparable to those to which issuers in more developed markets are subject. The fund's rights with respect to its investments in emerging markets, if any, will generally be governed by local law, which may make it difficult or impossible for the fund to pursue legal remedies or to obtain and enforce judgments in local courts. In addition, the economies of these countries may be dependent on relatively few industries, may have limited access to capital and may be more susceptible to changes in local and global trade conditions and downturns in the world economy. Securities markets in these countries can also be relatively small and have substantially lower trading volumes. As a result, securities issued in these countries may be more volatile and less liquid, more vulnerable to market manipulation, and more difficult to value, than securities issued in countries with more developed economies and/or markets. Less certainty with respect to security valuations may lead to additional challenges and risks in calculating the fund's net asset value. Additionally, emerging markets are more likely to experience problems with the clearing and settling of trades and the holding of securities by banks, agents and depositories that are less established than those in developed countries.

*Management* — The investment adviser to the fund actively manages the fund's investments. Consequently, the fund is subject to the risk that the methods and analyses, including models, tools and data, employed by the investment adviser in this process may be flawed or incorrect and may not produce the desired results. This could cause the fund to lose value or its investment results to lag relevant benchmarks or other funds with similar objectives.

The following are additional risks associated with investing in the fund.

*Exposure to country, region, industry or sector* — Subject to the fund's investment limitations, the fund may have significant exposure to a particular country, region, industry or sector. Such exposure may cause the fund to be more impacted by risks relating to and developments affecting the country, region, industry or sector, and thus its net asset value may be more volatile, than a fund without such levels of exposure. For example, if the fund has significant exposure in a particular country, then social, economic, regulatory or other issues that negatively affect that country may have a greater impact on the fund than on a fund that is more geographically diversified.

*Investing in depositary receipts* — Depositary receipts are securities that evidence ownership interests in, and represent the right to receive, a security or a pool of securities that have been deposited with a bank or trust depository. Such securities may be less liquid or may trade at a lower price than the underlying securities of the issuer. Additionally, receipt of corporate information about the underlying issuer and proxy disclosure may not be timely and there may not be a correlation between such information and the market value of the depositary receipts.

------

*Liquidity risk* — Certain fund holdings may be or may become difficult or impossible to sell, particularly during times of market turmoil. Liquidity may be impacted by the lack of an active market for a holding, legal or contractual restrictions on resale, or the reduced number and capacity of market participants to make a market in such holding. Market prices for less liquid or illiquid holdings may be volatile or difficult to determine, and reduced liquidity may have an adverse impact on the market price of such holdings. Additionally, the sale of less liquid or illiquid holdings may involve substantial delays (including delays in settlement) and additional costs and the fund may be unable to sell such holdings when necessary to meet its liquidity needs or to try to limit losses, or may be forced to sell at a loss.

*Lending of portfolio securities —* Securities lending involves risks, including the risk that the loaned securities may not be returned in a timely manner or at all, which would interfere with the fund's ability to vote proxies or settle transactions, and/or the risk of a counterparty default. Additionally, the fund may lose money from the reinvestment of collateral received on loaned securities in investments that decline in value, default or do not perform as expected.

*Cybersecurity breaches* — The fund may be subject to operational and information security risks through breaches in cybersecurity. Cybersecurity breaches can result from deliberate attacks or unintentional events, including "ransomware" attacks, the injection of computer viruses or malicious software code, the use of vulnerabilities in code to gain unauthorized access to digital information systems, networks or devices, or external attacks such as denial-of-service attacks on the investment adviser's or an affiliate's website that could render the fund's network services unavailable to intended end-users. These breaches may, among other things, lead to the unauthorized release of confidential information, misuse of the fund's assets or sensitive information, the disruption of the fund's operational capacity, the inability of fund shareholders to transact business, or the destruction of the fund's physical infrastructure, equipment or operating systems. These events could cause the fund to violate applicable privacy and other laws and could subject the fund to reputational damage, additional costs associated with corrective measures and/or financial loss. The fund may also be subject to additional risks if its third-party service providers, such as the fund's investment adviser, transfer agent, custodian, administrators and other financial intermediaries, experience similar cybersecurity breaches and potential outcomes. Cybersecurity risks may also impact issuers of securities in which the fund invests, which may cause the fund's investments in such issuers to lose value.

*Large shareholder transactions risk* — The fund may experience adverse effects when shareholders, including other funds or accounts advised by the investment adviser, purchase or redeem, individually or in the aggregate, large amounts of shares relative to the size of the fund. For example, when the investment adviser changes allocations in other funds and accounts it manages, such changes may result in shareholder transactions in the fund that are large relative to the size of the fund. Such large shareholder redemptions may cause the fund to sell portfolio securities at times when it would not otherwise do so, which may negatively impact the fund's net asset value and liquidity. Similarly, large fund share purchases may adversely affect the fund's performance to the extent that the fund is delayed in investing new cash and is required to maintain a larger cash position than it ordinarily would. These transactions may also accelerate the realization of taxable income to shareholders if such sales of investments resulted in gains, and may also increase transaction costs. In addition, a large redemption could result in the fund's current expenses being allocated over a smaller asset base, leading to an increase in the fund's expense ratio. These risks are heightened when the fund is small.

In addition to the principal investment strategies described above, the fund has other investment practices that are described in the statement of additional information, which includes a description of other risks related to the fund's principal investment strategies and other investment practices. The fund's investment results will depend on the ability of the fund's investment adviser to navigate the risks discussed above as well as those described in the statement of additional information.

**Fund comparative indexes** — The MSCI All Country World ex USA Index is a free float-adjusted market capitalization-weighted index that is designed to measure equity market results in the global developed and emerging markets, excluding the United States. The index consists of more than 40 developed and emerging market country indexes. Results reflect dividends net of withholding taxes. This index is unmanaged, and its results include reinvested dividends and/or distributions but do not reflect the effect of sales charges, commissions, account fees, expenses or U.S. federal income taxes.

**Portfolio holdings** A description of the fund's policies and procedures regarding disclosure of information about its portfolio holdings is available in the statement of additional information.

**Management and organization**

**Investment adviser** Capital Research and Management Company, an experienced investment management organization founded in 1931, serves as the investment adviser to the Series and other funds, including the American Funds. Capital Research and Management Company is a wholly owned subsidiary of The Capital Group Companies, Inc. and is located at 333 South Hope Street, Los Angeles, California 90071. Capital Research and Management Company manages the investment portfolios and business affairs of the Series. The total management fee paid by each fund to its investment adviser for the most recent fiscal year, including any amounts waived, in each case expressed as a percentage of average net assets of that fund, appears in the Annual Fund Operating Expenses table for each fund. Please see the statement of additional information for further details. A discussion regarding the basis for the approval of the Series' Investment Advisory and Service Agreement by the Series' board of trustees is contained in the Series' annual or semi-annual report in Form N-CSR for the most recent fiscal period.

Capital Research and Management Company manages equity assets through three equity investment divisions and fixed income assets through its fixed income investment division, Capital Fixed Income Investors. The three equity investment divisions — Capital International Investors, Capital Research Global Investors and Capital World Investors — make investment decisions independently of one another.

The equity investment divisions may, in the future, be incorporated as wholly owned subsidiaries of Capital Research and Management Company. In that event, Capital Research and Management Company would continue to be the investment adviser, and day-to-day investment management of equity assets would continue to be carried out through one or more of these subsidiaries. Although not currently contemplated, Capital Research and Management Company could incorporate its fixed income investment division in the future and engage it to provide day-to-day investment management of fixed income assets. Capital Research and Management Company and each of the funds it advises have received an exemptive order from the U.S. Securities and Exchange Commission that allows Capital Research and Management Company to use, upon approval of the funds' boards, its management subsidiaries and affiliates to provide day-to-day investment management services to the funds, including making changes to the management subsidiaries and affiliates providing such services. The Series' shareholders approved this arrangement; however, there is no assurance that Capital Research and Management Company will incorporate its investment divisions or exercise any authority granted to it under the exemptive order.

In addition, shareholders of the Series have approved a proposal to reorganize the Series into a Delaware statutory trust. However, the Series reserved the right to delay implementing the reorganization and has elected to do so.

**The Capital System<sup>TM</sup>** Capital Research and Management Company uses a system of multiple portfolio managers in managing fund assets. Under this approach, the portfolio of a fund is divided into segments managed by individual managers. In addition, Capital Research and Management Company's investment analysts may make investment decisions with respect to a portion of each underlying fund's portfolio. Investment decisions are subject to a fund's objective(s), policies and restrictions and the oversight of the appropriate investment-related committees of Capital Research and Management Company and its investment divisions.

Certain senior members of Capital Fixed Income Investors, the investment adviser's fixed income investment division, serve on the Portfolio Strategy Group. The group utilizes a research-driven process with input from the investment adviser's analysts, portfolio managers and economists to define investment themes on a range of macroeconomic factors, including duration, yield curve and sector allocation. Where applicable, the investment decisions made by a fund's fixed income portfolio managers are informed by the investment themes discussed by the group.

**Purchases and redemptions of shares** Shares of the Series are currently offered only to insurance company separate accounts as well as so-called "feeder funds" under master-feeder arrangements sponsored by insurance companies as underlying investments for such insurance companies' variable annuity contracts and variable life insurance policies. All such shares may be purchased or redeemed by the insurance company separate accounts (or feeder funds) at net asset value without any sales or redemption charges. These purchases and redemptions are made at the price next determined after such purchases and redemptions of units of the separate accounts (or feeder funds). The Series typically expects to remit redemption proceeds one business day following receipt and acceptance of a redemption order, regardless of the method the Series uses to make such payment (e.g., check, wire or automated clearing house transfer). However, payment may take longer than one business day and may take up to seven days as generally permitted by the Investment Company Act of 1940, as amended (the "1940 Act"). Under the 1940 Act, the Series may be permitted to pay redemption proceeds beyond seven days under certain limited circumstances.

Under normal conditions, the Series typically expects to meet shareholder redemptions from a reserve of highly liquid assets, such as cash or cash equivalents. The Series may use additional methods to meet shareholder redemptions, if they become necessary. These methods may include, but are not limited to, the sale of portfolio assets, the use of overdraft protection afforded by the Series' custodian bank, borrowing from a line of credit and making payment with fund securities or other fund assets rather than in cash (as further discussed in the following paragraph).

Although payment of redemptions normally will be in cash, the Series may pay the redemption price wholly or partly with portfolio securities or other fund assets under conditions and circumstances determined by the Series' board of trustees. On the same redemption date, some shareholders may be paid in whole or in part in securities (which may differ among those shareholders), while other shareholders may be paid entirely in cash. In general, in-kind redemptions to affiliated shareholders will as closely as practicable represent the affiliated shareholder's pro rata share of the Series' securities, subject to certain exceptions. Securities distributed in-kind to unaffiliated shareholders will be selected by the investment adviser in a manner the investment adviser deems to be fair and reasonable to the Series' shareholders. The disposal of the securities received in-kind may be subject to brokerage costs and, until sold, such securities remain subject to market risk and liquidity risk, including the risk that such securities are or become difficult to sell. If the Series pays your redemption with illiquid or less liquid securities, you will bear the risk of not being able to sell such securities.

**Frequent trading of fund shares** The Series and Capital Client Group, Inc., the Series' distributor, reserve the right to reject any purchase order for any reason. The funds are not designed to serve as vehicles for frequent trading. Frequent trading of fund shares may lead to increased costs to the funds and less efficient management of the funds' portfolios, potentially resulting in dilution of the value of the shares held by long-term shareholders. Accordingly, purchases, including those that are part of exchange activity, that the Series or Capital Client Group, Inc. has determined could involve actual or potential harm to a fund may be rejected.

The Series, through its transfer agent, American Funds Service Company, has agreements with the Series' insurance relationships to maintain its surveillance procedures that are designed to detect frequent trading in fund shares. The agreements generally require the insurance companies to (i) provide, upon request from a fund, the Series or their agent, certain identifying and account information regarding contract owners who invest in fund shares through an insurance company account and (ii) execute instructions from a fund, the Series or their agent to restrict further purchases or exchanges of fund shares by a contract owner who the Series has identified as having engaged in potentially harmful market timing or frequent trading. Under these procedures, various analytics are used to evaluate factors that may be indicative of frequent trading. For example, transactions in fund shares that exceed certain monetary thresholds may be scrutinized. American Funds Service Company may work with the insurance company separate accounts or feeder funds to apply their procedures that American Funds Service Company believes are reasonably designed to enforce the frequent trading policies of the Series. You should refer to disclosures provided by the insurance company with which you have a contract to determine the specific trading restrictions that apply to you.

Under the Series' frequent trading policy, certain trading activity will not be treated as frequent trading, such as:

· retirement plan contributions, loans and distributions (including hardship withdrawals) identified as such on the retirement plan recordkeeper's system;

· purchases and redemptions in community foundation accounts;

· purchase transactions involving in-kind transfers of fund shares, if the entity maintaining the contract owner's account is able to identify the transaction as one of these types of transactions;

· transactions by certain intermediaries in accordance with established hedging programs approved by the fund's investment adviser; and

· systematic redemptions and purchases if the entity maintaining the contract owner's account is able to identify the transaction as a systematic redemption or purchase.

Generally, purchases and redemptions will not be considered "systematic" unless the transaction is prescheduled for a specific date.

American Funds Service Company will monitor for other types of activity that could potentially be harmful to the Series – for example short-term trading activity in multiple funds. If American Funds Service Company identifies any activity that may constitute frequent trading, it reserves the right to contact the insurance company separate account or feeder fund and request that the separate account or feeder fund either provide information regarding an account owner's transactions or restrict the account owner's trading. If American Funds Service Company is not satisfied that insurance company separate account or feeder fund has taken appropriate action, American Funds Service Company may terminate the separate account's or feeder fund's ability to transact in fund shares.

There is no guarantee that all instances of frequent trading in fund shares will be prevented.

**Notwithstanding the Series' surveillance procedures described above, all transactions in fund shares remain subject to the right of the Series, Capital Client Group, Inc. and American Funds Service Company to restrict potentially abusive trading generally, including the types of transactions described above that will not be prevented.**

**Valuing shares** The net asset value of each share class of a fund is the value of a single share of that class. Net asset value is computed by adding a class's share of the value of a fund's investments, cash and other assets, subtracting the class's share of the fund's liabilities allocated to the class, and dividing the result by the number of shares of that class that are outstanding. Realized investment income and gain is included in the fund's net asset value until the ex-dividend date, when the declared dividend amount is treated as a fund liability. The net asset value per share is calculated once daily as of the close of regular trading on the New York Stock Exchange, normally 4 p.m. New York time, each day the New York Stock Exchange is open. If the New York Stock Exchange makes a scheduled (e.g., the day after Thanksgiving) or an unscheduled close prior to 4 p.m. New York time, the net asset value of each fund will be determined at approximately the time the New York Stock Exchange closes on that day. If on such a day market quotations and prices from third-party pricing services are not based as of the time of the early close of the New York Stock Exchange but are as of a later time (up to approximately 4 p.m. New York time), for example because the market remains open after the close of the New York Stock Exchange, those later market quotations and prices will be used in determining the funds' net asset value.

Equity securities are valued primarily on the basis of market quotations, and debt securities are valued primarily on the basis of prices from third-party pricing services due to the lack of market quotations. Futures contracts are valued primarily on the basis of settlement prices. The funds' portfolio investments are valued in accordance with procedures for making fair value determinations if market quotations are not readily available, including procedures to determine the representativeness of third-party vendor prices, or in the event market quotations or third-party vendor prices are not considered reliable. For example, if events occur between the close of markets outside the United States and the close of regular trading on the New York Stock Exchange that, in the opinion of the investment adviser, materially affect the value of any of the funds' equity securities that trade principally in those international markets, those securities will be valued in accordance with fair value procedures. Similarly, fair value procedures will be employed if an issuer defaults on its debt securities and there is no market for its securities. Use of these procedures is intended to result in more appropriate net asset values and, where applicable, to reduce potential arbitrage opportunities otherwise available to short-term investors.

Because certain of the funds may hold securities that are listed primarily on foreign exchanges that trade on weekends or days when the funds do not price their shares, the values of securities held in the funds may change on days when you will not be able to purchase or redeem fund shares.

Shares of the funds will be purchased or sold at the net asset value next determined after receipt of requests from the appropriate insurance company. Requests received by the appropriate insurance company prior to 4 p.m. New York time and communicated by the insurance company to the Series or its agent will be purchased or sold at that day's net asset value. Orders in good order received after the New York Stock Exchange closes (scheduled or unscheduled) will be processed at the net asset value (plus any applicable sales charge) calculated on the following business day.

**Plan of distribution** The Series has adopted a plan of distribution or "12b-1 plan" for Class 3 shares. Under the plan, the Series may finance activities primarily intended to sell shares, provided the categories of expenses are approved in advance by the Series' board of trustees. The plan provides for annual expenses of .18% for Class 3 shares. Amounts paid under the 12b-1 plan are used by insurance company contract issuers to cover distribution expenses and/or the expenses of certain contract owner services. The 12b-1 fees paid by the Series, as a percentage of average net assets, for the most recent fiscal year, are indicated in the prospectus in the Annual Fund Operating Expenses table for each fund. Since these fees are paid out of the Series' assets on an ongoing basis, over time they may cost you more than paying other types of sales charges or service fees and reduce the return of an investment in Class 3 shares.

**Other compensation to dealers** Capital Client Group, Inc., at its expense, provides additional compensation to insurance companies. These payments may be made, at the discretion of Capital Client Group, Inc., to insurance companies (or their affiliates) that have sold shares of the funds of the American Funds Insurance Series and American Funds as the exclusive underlying investments to their variable annuity contracts. A number of factors will be considered in determining payments, including the sales, assets, and the quality of the insurance company's relationship with Capital Client Group, Inc. The payment will typically be determined using a formula applied consistently to insurance companies based on the relevant facts and circumstances. Aggregate payments made by Capital Client Group, Inc. to insurance companies may also change from year to year. Only assets and deposits in variable annuity contracts that offer exclusively shares of the funds of the American Funds Insurance Series and American Funds are included in the formula. Further, assets for which the insurance company, or an affiliated broker-dealer, acts as an ERISA investment fiduciary are generally excluded from the formula. Capital Client Group, Inc. makes these payments to help defray the costs incurred by qualifying insurance companies in connection with efforts to educate their sales force about the American Funds Insurance Series and American Funds so that they help financial advisers make recommendations and provide services that are suitable and meet contractholders' needs. These payments may also be made to help defray the costs associated with the insurance company's provision of account-related services and activities and support the insurance company's distribution activities. Capital Client Group, Inc. will, on a periodic basis, determine the advisability of continuing these payments. As of May 1, 2026, the insurance companies (or their affiliates) that Capital Client Group, Inc. anticipates will receive additional compensation based on prior payments include Lincoln National Life Insurance Co.

Firms receiving additional compensation payments must sign a letter acknowledging the purpose of the payment and Capital Client Group, Inc.'s goal that the payment will help facilitate education of their sales force about the American Funds Insurance Series and American Funds to help financial professionals make suitable recommendations and better serve their clients who invest in the funds as underlying investments to variable annuity contracts. The letters generally require the firms to (1) offers shares of the funds of the American Funds Insurance Series and American Funds as the exclusive underlying investments to their variable annuity contracts, and (2) provide Capital Client Group, Inc. broad access to their sales force and product platforms and develop a business plan to achieve such access.

Capital Client Group, Inc. may also pay expenses associated with meetings and other training and educational opportunities conducted by insurance companies, selling dealers, advisory platform providers and other intermediaries to facilitate educating financial professionals and shareholders about the American Funds Insurance Series and American Funds. For example, some of these expenses may include, but not be limited to, meeting sponsor fees, meeting location fees, fees for data and reporting, and fees to obtain lists of financial professionals to better tailor training and education opportunities. In addition, Capital Client Group, Inc. and/or its affiliates may make payments to third parties for platform fees and other services.

If investment advisers, distributors or other affiliates of mutual funds pay additional compensation or other incentives to insurance companies in differing amounts, insurance companies and the financial professionals with which they interact may have financial incentives for recommending a particular mutual fund over other mutual funds or investments, creating a potential conflict of interest. You should consult with your financial professional and review carefully any disclosure by your financial professional's firm as to compensation received.

**Fund expenses** In periods of market volatility, assets of the funds may decline significantly, causing total annual fund operating expenses (as a percentage of the value of your investment) to become higher than the numbers shown in the Annual Fund Operating Expenses tables in this prospectus.

The "Other expenses" items in the Annual Fund Operating Expenses tables in this prospectus are based on expenses as of each fund's most recently completed fiscal year. These items include third-party expenses, such as custodial, legal, audit, accounting, regulatory reporting and pricing vendor services, and an administrative services fee payable to the Series' investment adviser for administrative services provided by the Series' investment adviser and its affiliates.

For all share classes, "Other expenses" items in the Annual Fund Operating Expenses table in this prospectus include fees for administrative services provided by the fund's investment adviser and its affiliates. Administrative services are provided by the investment adviser and its affiliates to help assist third parties providing non-distribution services to fund shareholders. These services include providing in-depth information on the fund and market developments that impact fund investments. Administrative services also include, but are not limited to, coordinating, monitoring and overseeing third parties that provide services to fund shareholders.

The Administrative Services Agreement between the fund and the investment adviser provides the fund the ability to charge an administrative services fee of .05% for all share classes. The fund's investment adviser receives an administrative services fee at the annual rate of .03% of the average daily net assets of the fund attributable to all share classes (which could be increased as noted above) for its provision of administrative services.

**Investment results** All fund results in the "Investment results" section of this prospectus reflect the reinvestment of dividends and capital gains distributions, if any. Unless otherwise noted, fund results reflect any fee waivers and/or expense reimbursements in effect during the period presented.

**Distributions and taxes** Each fund of the Series intends to qualify as a "regulated investment company" under the Internal Revenue Code. In any fiscal year in which a fund so qualifies and distributes to shareholders its investment company taxable income and net realized capital gain, the fund itself is relieved of federal income tax.

It is the Series' policy to distribute to the shareholders (the insurance company separate accounts) all of its investment company taxable income and capital gain for each fiscal year.

**Financial highlights** The Financial Highlights table is intended to help you understand a fund's results for the past five fiscal years (or, if shorter, the period of operations). Certain information reflects financial results for a single share of a particular class. The total returns in the table represent the rate that an investor would have earned or lost on an investment in a fund (assuming reinvestment of all dividends and capital gain distributions). Where indicated, figures in the table reflect the impact, if any, of certain waivers from Capital Research and Management Company. For more information about these waivers, see the fund's statement of additional information and Form N-CSR. The information in the Financial Highlights table has been audited by PricewaterhouseCoopers LLP, whose current report, along with the funds' financial statements, is included in the statement of additional information, which is available upon request. Figures shown do not reflect insurance contract fees and expenses. If insurance contract fees and expenses were reflected, results would be lower.

**The U.S. Securities and Exchange Commission has not approved or disapproved of these securities. Further, it has not determined that this prospectus is accurate or complete. Any representation to the contrary is a criminal offense.**

 **SMALLCAP World Fund** 

**Investment objective** The fund's investment objective is to provide you with long-term growth of capital.

**Fees and expenses of the fund** This table describes the fees and expenses that you may pay if you buy, hold and sell an interest in Class 4 shares of the fund. **You may pay other fees, such as insurance contract fees and expenses, which are not reflected in the tables and examples below.** If insurance contract fees and expenses were reflected, expenses shown would be higher.

|:---|:---|
| **Annual fund operating expenses (expenses that you pay each year as a percentage of the net asset value of your investment)** | Class 4 |
| Management fee | 0.65% |
| Distribution (12b-1) fees | 0.25 |
| Other expenses | 0.30 |
| Total annual fund operating expenses | 1.20 |
| Fee waiver\* | 0.05 |
| Total annual fund operating expenses after fee waiver | 1.15 |

\* The investment adviser is currently waiving a portion of its management fee equal to 0.05% of the fund's net assets. This waiver will be in effect through at least May 1, 2027. The waiver may only be modified or terminated with the approval of the fund's board.

**Example** This example is intended to help you compare the cost of investing in Class 4 shares of the fund with the cost of investing in other mutual funds.

The example assumes that you invest $10,000 in the fund for the time periods indicated and then redeem or hold all of your shares at the end of those periods. The example also assumes that your investment has a 5% return each year and that the fund's operating expenses remain the same. The example does not reflect insurance contract expenses. If insurance contract expenses were reflected, expenses shown would be higher. The example reflects the fee waiver described above through the expiration date of such waiver and total annual fund operating expenses thereafter. No sales charge (load) or other fees are charged by the fund upon redemption, so you would incur these hypothetical costs whether or not you were to redeem your shares at the end of the given period. Although your actual costs may be higher or lower, based on these assumptions your costs would be:

---

| | | | | |
|:---|:---|:---|:---|:---|
|  | 1 year | 3 years | 5 years | 10 years |
| Class 4 | $117 | $376 | $655 | $1450 |

---

**Portfolio turnover** The fund pays transaction costs, such as commissions, when it buys and sells securities (or "turns over" its portfolio). A higher portfolio turnover rate may indicate higher transaction costs. These costs, which are not reflected in annual fund operating expenses or in the example, affect the fund's investment results. During the most recent fiscal year, the fund's portfolio turnover rate was 51% of the average value of its portfolio.

**Principal investment strategies** Normally the fund invests at least 80% of its net assets in common stocks and other equity-type securities (such as preferred stocks, convertible preferred stocks and convertible bonds) of companies with small market capitalizations, including growth-oriented stocks. The investment adviser currently defines "small market capitalization" companies to be companies with market capitalizations within or below the capitalization range of companies included in the MSCI All Country World Small Cap Index or the Russell 2000 Index, measured based on the maximum market capitalization of companies in either index within the last 12 months. As of August 31, 2025, the largest company in the MSCI All Country World Small Cap Index had a market capitalization of approximately $25.9 billion and the largest company in the Russell 2000 Index had a market capitalization of approximately $20.9 billion. The market capitalization of the companies included in the MSCI All Country World Small Cap Index and the Russell 2000 Index will change with market conditions. The investment adviser has periodically re-evaluated and adjusted this definition and may continue to do so in the future. The fund may continue to hold securities of a portfolio company that subsequently appreciates above the small market capitalization threshold. Under normal circumstances, the fund will invest a significant portion of its assets outside the United States, including in emerging markets.

Prior to May 1, 2026, the fund was called Global Small Capitalization Fund.

The investment adviser uses a system of multiple portfolio managers in managing the fund's assets. Under this approach, the portfolio of the fund is divided into segments managed by individual managers.

The fund relies on the professional judgment of its investment adviser to make decisions about the fund's portfolio investments. The basic investment philosophy of the investment adviser is to seek to invest in attractively valued companies that, in its opinion, represent good, long-term investment opportunities. Securities may be sold when the investment adviser believes that they no longer represent relatively attractive investment opportunities.

**Principal risks This section describes the principal risks associated with investing in the fund. You may lose money by investing in the fund. The likelihood of loss may be greater if you invest for a shorter period of time.** 

*Market conditions* — The prices of, and the income generated by, the securities held by the fund may decline – sometimes rapidly or unpredictably – due to various factors, including events or conditions affecting the general economy or particular industries or companies; overall market changes; local, regional or global political, social or economic instability; governmental, governmental agency or central bank responses to economic conditions; levels of public debt and deficits; changes in inflation rates; and currency exchange rate, interest rate and commodity price fluctuations.

Economies and financial markets throughout the world are highly interconnected. Economic, financial or political events, trading and tariff arrangements, wars, terrorism, cybersecurity events, natural disasters, public health emergencies (such as the spread of infectious disease), bank failures and other circumstances in one country or region, including actions taken by governmental or quasi-governmental authorities in response to any of the foregoing, could have impacts on global economies or markets. As a result, whether or not the fund invests in securities of issuers located in or with significant exposure to the countries affected, the value and liquidity of the fund's investments may be negatively affected by developments in other countries and regions.

*Issuer risks* — The prices of, and the income generated by, securities held by the fund may decline in response to various factors directly related to the issuers of such securities, including reduced demand for an issuer's goods or services, poor management performance, major litigation, investigations or other controversies related to the issuer, changes in the issuer's financial condition or credit rating, changes in government regulations affecting the issuer or its competitive environment and strategic initiatives such as mergers, acquisitions or dispositions and the market response to any such initiatives. An individual security may also be affected by factors relating to the industry or sector of the issuer or the securities markets as a whole, and conversely an industry or sector or the securities markets may be affected by a change in financial condition or other event affecting a single issuer.

*Investing in growth-oriented stocks* — Growth-oriented common stocks and other equity-type securities (such as preferred stocks, convertible preferred stocks and convertible bonds) may involve larger price swings and greater potential for loss than other types of investments. These risks may be even greater in the case of smaller capitalization stocks.

*Investing in small companies* — Investing in smaller companies may pose additional risks. For example, it is often more difficult to value or dispose of small company stocks and more difficult to obtain information about smaller companies than about larger companies. Furthermore, smaller companies often have limited product lines, operating histories, markets and/or financial resources, may be dependent on one or a few key persons for management, and can be more susceptible to losses. Moreover, the prices of their stocks may be more volatile than stocks of larger, more established companies, particularly during times of market turmoil.

*Investing outside the United States* — Securities of issuers domiciled outside the United States or with significant operations or revenues outside the United States, and securities tied economically to countries outside the United States, may lose value because of adverse political, social, economic or market developments (including social instability, regional conflicts, terrorism and war) in the countries or regions in which the issuers are domiciled, operate or generate revenue or to which the securities are tied economically. These securities may also lose value due to changes in foreign currency exchange rates against the U.S. dollar and/or currencies of other countries. Issuers of these securities may be more susceptible to actions of foreign governments, such as nationalization, currency blockage or the imposition of price controls, sanctions, or punitive taxes, each of which could adversely impact the value of these securities. Securities markets in certain countries may be more volatile and/or less liquid than those in the United States. Investments outside the United States may also be subject to different regulatory, legal, accounting, auditing, financial reporting and recordkeeping requirements, and may be more difficult to value, than those in the United States. In addition, the value of investments outside the United States may be reduced by foreign taxes, including foreign withholding taxes on interest and dividends. Further, there may be increased risks of delayed settlement of securities purchased or sold by the fund, which could impact the liquidity of the fund's portfolio. The risks of investing outside the United States may be heightened in connection with investments in emerging markets.

------

*Investing in emerging markets* — Investing in emerging markets may involve risks in addition to and greater than those generally associated with investing in the securities markets of developed countries. For instance, emerging market countries tend to have less developed political, economic and legal systems than those in developed countries. Accordingly, the governments of these countries may be less stable and more likely to intervene in the market economy, for example, by imposing capital controls, nationalizing a company or industry, placing restrictions on foreign ownership and on withdrawing sale proceeds of securities from the country, and/or imposing punitive taxes that could adversely affect the prices of securities. Information regarding issuers in emerging markets may be limited, incomplete or inaccurate, and such issuers may not be subject to regulatory, accounting, auditing, and financial reporting and recordkeeping standards comparable to those to which issuers in more developed markets are subject. The fund's rights with respect to its investments in emerging markets, if any, will generally be governed by local law, which may make it difficult or impossible for the fund to pursue legal remedies or to obtain and enforce judgments in local courts. In addition, the economies of these countries may be dependent on relatively few industries, may have limited access to capital and may be more susceptible to changes in local and global trade conditions and downturns in the world economy. Securities markets in these countries can also be relatively small and have substantially lower trading volumes. As a result, securities issued in these countries may be more volatile and less liquid, more vulnerable to market manipulation, and more difficult to value, than securities issued in countries with more developed economies and/or markets. Less certainty with respect to security valuations may lead to additional challenges and risks in calculating the fund's net asset value. Additionally, emerging markets are more likely to experience problems with the clearing and settling of trades and the holding of securities by banks, agents and depositories that are less established than those in developed countries.

*Liquidity risk* — Certain fund holdings may be or may become difficult or impossible to sell, particularly during times of market turmoil. Liquidity may be impacted by the lack of an active market for a holding, legal or contractual restrictions on resale, or the reduced number and capacity of market participants to make a market in such holding. Market prices for less liquid or illiquid holdings may be volatile or difficult to determine, and reduced liquidity may have an adverse impact on the market price of such holdings. Additionally, the sale of less liquid or illiquid holdings may involve substantial delays (including delays in settlement) and additional costs and the fund may be unable to sell such holdings when necessary to meet its liquidity needs or to try to limit losses, or may be forced to sell at a loss.

*Management* — The investment adviser to the fund actively manages the fund's investments. Consequently, the fund is subject to the risk that the methods and analyses, including models, tools and data, employed by the investment adviser in this process may be flawed or incorrect and may not produce the desired results. This could cause the fund to lose value or its investment results to lag relevant benchmarks or other funds with similar objectives.

Your investment in the fund is not a bank deposit and is not insured or guaranteed by the Federal Deposit Insurance Corporation or any other governmental agency, entity or person. You should consider how this fund fits into your overall investment program.

**Investment results** The following bar chart shows how the investment results of the Class 4 shares of the fund have varied from year to year, and the following table shows how the fund's average annual total returns for various periods compare with a broad measure of securities market results and, if applicable, other measures of market results that reflect the fund's investment universe. This information provides some indication of the risks of investing in the fund. Past investment results (before and after taxes) are not predictive of future investment results. Figures shown reflect fees and expenses associated with an investment in the fund, but do not reflect insurance contract fees and expenses. If insurance contract fees and expenses were included, results would have been lower. Updated information on the fund's investment results can be obtained by visiting capitalgroup.com/afis.

\*Lifetime returns are from April 30, 1998, the date the fund began investment operations. Class 4 shares began investment operations on December 14, 2012; therefore, returns for the fund prior to that date assume a hypothetical investment in Class 1 shares, but reflect the .50% annual expense that applies to Class 4 shares, .25% of which is described in the "Plan of distribution" section of this prospectus and .25% of which is described in the "Fund expenses" section of this prospectus. Returns for Class 1 shares are comparable to those of Class 4 shares because both classes invest in the same portfolio of securities.

**Purchase and sale of fund shares** Shares of the fund are not sold directly to the general public. The fund is offered only as an underlying investment option for variable insurance contracts, and insurance company separate accounts and qualified feeder funds — and not the holders of variable insurance contracts — are the shareholders of the fund. Although the fund does not require a minimum amount for initial or subsequent purchases from insurance companies, your insurance company may impose investment minimums for your purchase of the fund.

You may sell (redeem) shares on any business day. You must sell (redeem) shares through your insurance company.

**Tax information** See your variable insurance contract prospectus for information regarding the federal income tax treatment of your variable insurance contract and related distributions.

**Payments to broker-dealers and other financial intermediaries** The fund is not sold directly to the general public but instead is offered as an underlying investment option for variable insurance contracts. The fund and its related companies may make payments to the sponsoring insurance company (or its affiliates) for distribution and/or other services. These payments may be a factor that the insurance company considers in including the fund as an underlying investment option in the variable insurance contract. The prospectus (or other offering document) for your variable insurance contract may contain additional information about these payments.

A higher portfolio turnover rate may indicate higher transaction costs. These costs, which are not reflected in annual fund operating expenses or in the example, affect the fund's investment results. During the most recent fiscal year, the fund's portfolio turnover rate was 63% of the average value of its portfolio.

**Principal investment strategies** The fund invests primarily in common stocks in Europe and the Pacific Basin that the investment adviser believes have the potential for growth. Growth stocks are stocks that the investment adviser believes have the potential for above-average capital appreciation.

Normally the fund will invest at least 80% of its net assets in securities of issuers in Europe and the Pacific Basin. A country will be considered part of Europe if it is part of the MSCI European indexes, and part of the Pacific Basin if any of its borders touches the Pacific Ocean. In determining the domicile of an issuer, the fund's investment adviser will generally look to the determination of MSCI Inc. (MSCI) for equity securities and Bloomberg for debt securities. In certain limited circumstances (including where relevant data is unavailable or the nature of a holding warrants special considerations), the adviser may also take into account additional factors, as applicable, including where the issuer's securities are listed; where the issuer is legally organized, maintains principal corporate offices, conducts its principal operations, generates revenues and/or has credit risk exposure; and the source of guarantees, if any, of such securities. The fund may invest a portion of its assets in common stocks and other securities of companies in emerging markets.

Prior to May 1, 2026, the fund was called International Fund.

The investment adviser uses a system of multiple portfolio managers in managing the fund's assets. Under this approach, the portfolio of the fund is divided into segments managed by individual managers.

While it has no present intention to do so, the fund's board may change the fund's investment objective without shareholder approval upon 60 days' prior written notice to shareholders. Normally the fund invests at least 80% of its net assets in common stocks and other equity-type securities (such as preferred stocks, convertible preferred stocks and convertible bonds) of companies with small market capitalizations, including growth-oriented stocks. This policy is subject to change only upon 60 days' prior written notice to shareholders. The investment adviser currently defines "small market capitalization" companies to be companies with market capitalizations within or below the capitalization range of companies included in the MSCI All Country World Small Cap Index or the Russell 2000 Index, measured based on the maximum market capitalization of companies in either index within the last 12 months. As of August 31, 2025, the largest company in the MSCI All Country World Small Cap Index had a market capitalization of approximately $25.9 billion and the largest company in the Russell 2000 Index had a market capitalization of approximately $20.9 billion. The market capitalization of the companies included in the MSCI All Country World Small Cap Index and the Russell 2000 Index will change with market conditions. The investment adviser has periodically re-evaluated and adjusted this definition and may continue to do so in the future. The fund may continue to hold securities of a portfolio company that subsequently appreciates above the small market capitalization threshold. Under normal circumstances, the fund will invest a significant portion of its assets outside the United States, including in emerging markets.

The fund may also hold cash or cash equivalents, including commercial paper and short-term securities issued by the U.S. government, its agencies and instrumentalities. The percentage of the fund invested in such holdings varies and depends on various factors, including market conditions and purchases and redemptions of fund shares. The investment adviser may determine that it is appropriate to invest a substantial portion of the fund's assets in such instruments in response to certain circumstances, such as periods of market turmoil. For temporary defensive purposes, the fund may invest without limitation in such instruments. A larger percentage of such holdings could moderate the fund's investment results in a period of rising market prices. Alternatively, a larger percentage of such holdings could reduce the magnitude of the fund's loss in a period of falling market prices and provide liquidity to make additional investments or to meet redemptions.

The fund may invest in certain other funds managed by the investment adviser or its affiliates ("Central Funds") to more effectively invest in a diversified set of securities in a specific asset class such as money market instruments, bonds and other securities. Shares of Central Funds are only offered for purchase to the fund's investment adviser and its affiliates and other funds, investment vehicles and accounts managed by the fund's investment adviser and its affiliates. Central Funds do not charge management fees. As a result, the fund does not bear additional management fees when investing in Central Funds, but the fund does bear its proportionate share of Central Fund expenses. The investment results of the portions of the fund's assets invested in the Central Funds will be based upon the investment results of the Central Funds.

The fund may also lend portfolio securities to brokers, dealers and other institutions that provide cash or U.S. Treasury securities as collateral in an amount at least equal to the value of the securities loaned.

Prior to May 1, 2026, the fund was called Global Small Capitalization Fund.

The fund relies on the professional judgment of its investment adviser to make decisions about the fund's portfolio investments. The basic investment philosophy of the investment adviser is to seek to invest in attractively valued companies that, in its opinion, represent good, long-term investment opportunities. The investment adviser believes that an important way to accomplish this is through fundamental analysis, which may include meeting with company executives and employees, suppliers, customers and competitors. Securities may be sold when the investment adviser believes that they no longer represent relatively attractive investment opportunities.

The investment adviser may consider environmental, social and governance ("ESG") factors that, depending on the facts and circumstances, are material to the value of an issuer or instrument. ESG factors may include, but are not limited to, environmental issues (e.g., water use, emission levels, waste, environmental remediation), social issues (e.g., human capital, health and safety, changing customer behavior) or governance issues (e.g., board composition, executive compensation, shareholder dilution).

The following are principal risks associated with investing in the fund.

*Market conditions* — The prices of, and the income generated by, the securities held by the fund may decline – sometimes rapidly or unpredictably – due to various factors, including events or conditions affecting the general economy or particular industries or companies; overall market changes; local, regional or global political, social or economic instability; governmental, governmental agency or central bank responses to economic conditions; levels of public debt and deficits; changes in inflation rates; and currency exchange rate, interest rate and commodity price fluctuations.

Economies and financial markets throughout the world are highly interconnected. Economic, financial or political events, trading and tariff arrangements, wars, terrorism, cybersecurity events, natural disasters, public health emergencies (such as the spread of infectious disease), bank failures and other circumstances in one country or region, including actions taken by governmental or quasi-governmental authorities in response to any of the foregoing, could have impacts on global economies or markets. As a result, whether or not the fund invests in securities of issuers located in or with significant exposure to the countries affected, the value and liquidity of the fund's investments may be negatively affected by developments in other countries and regions.

*Issuer risks* — The prices of, and the income generated by, securities held by the fund may decline in response to various factors directly related to the issuers of such securities, including reduced demand for an issuer's goods or services, poor management performance, major litigation, investigations or other controversies related to the issuer, changes in the issuer's financial condition or credit rating, changes in government regulations affecting the issuer or its competitive environment and strategic initiatives such as mergers, acquisitions or dispositions and the market response to any such initiatives. An individual security may also be affected by factors relating to the industry or sector of the issuer or the securities markets as a whole, and conversely an industry or sector or the securities markets

------

may be affected by a change in financial condition or other event affecting a single issuer. To the extent that the market prices of securities of issuers in the same or related industries or sectors tend to move in the same direction at the same time, and these issuers make up a sizeable portion of the market, events affecting one issuer, industry or sector or the securities markets generally may have a larger impact. If such issuers represent a substantial portion of major market indices, or the economy, a downturn in the prices of their securities may have a disproportionate adverse effect on the overall market, even if other segments of the market perform well. The fund's portfolio managers invest in issuers based on their level of investment conviction. At times, the fund may invest more significantly in a single issuer, which could increase the fund's volatility and the risk of loss arising from the factors described above.

*Investing in growth-oriented stocks* — Growth-oriented common stocks and other equity-type securities (such as preferred stocks, convertible preferred stocks and convertible bonds) may involve larger price swings and greater potential for loss than other types of investments. These risks may be even greater in the case of smaller capitalization stocks.

*Investing in small companies* — Investing in smaller companies may pose additional risks. For example, it is often more difficult to value or dispose of small company stocks and more difficult to obtain information about smaller companies than about larger companies. Furthermore, smaller companies often have limited product lines, operating histories, markets and/or financial resources, may be dependent on one or a few key persons for management, and can be more susceptible to losses. Moreover, the prices of their stocks may be more volatile than stocks of larger, more established companies, particularly during times of market turmoil.

*Investing outside the United States* — Securities of issuers domiciled outside the United States or with significant operations or revenues outside the United States, and securities tied economically to countries outside the United States, may lose value because of adverse political, social, economic or market developments (including social instability, regional conflicts, terrorism and war) in the countries or regions in which the issuers are domiciled, operate or generate revenue or to which the securities are tied economically. These securities may also lose value due to changes in foreign currency exchange rates against the U.S. dollar and/or currencies of other countries. Issuers of these securities may be more susceptible to actions of foreign governments, such as nationalization, currency blockage or the imposition of price controls, sanctions, or punitive taxes, each of which could adversely impact the value of these securities. Securities markets in certain countries may be more volatile and/or less liquid than those in the United States. Investments outside the United States may also be subject to different regulatory, legal, accounting, auditing, financial reporting and recordkeeping requirements, and may be more difficult to value, than those in the United States. In addition, the value of investments outside the United States may be reduced by foreign taxes, including foreign withholding taxes on interest and dividends. Further, there may be increased risks of delayed settlement of securities purchased or sold by the fund, which could impact the liquidity of the fund's portfolio. The risks of investing outside the United States may be heightened in connection with investments in emerging markets.

*Investing in emerging markets* — Investing in emerging markets may involve risks in addition to and greater than those generally associated with investing in the securities markets of developed countries. For instance, emerging market countries tend to have less developed political, economic and legal systems than those in developed countries. Accordingly, the governments of these countries may be less stable and more likely to intervene in the market economy, for example, by imposing capital controls, nationalizing a company or industry, placing restrictions on foreign ownership and on withdrawing sale proceeds of securities from the country, and/or imposing punitive taxes that could adversely affect the prices of securities. Information regarding issuers in emerging markets may be limited, incomplete or inaccurate, and such issuers may not be subject to regulatory, accounting, auditing, and financial reporting and recordkeeping standards comparable to those to which issuers in more developed markets are subject. The fund's rights with respect to its investments in emerging markets, if any, will generally be governed by local law, which may make it difficult or impossible for the fund to pursue legal remedies or to obtain and enforce judgments in local courts. In addition, the economies of these countries may be dependent on relatively few industries, may have limited access to capital and may be more susceptible to changes in local and global trade conditions and downturns in the world economy. Securities markets in these countries can also be relatively small and have substantially lower trading volumes. As a result, securities issued in these countries may be more volatile and less liquid, more vulnerable to market manipulation, and more difficult to value, than securities issued in countries with more developed economies and/or markets. Less certainty with respect to security valuations may lead to additional challenges and risks in calculating the fund's net asset value. Additionally, emerging markets are more likely to experience problems with the clearing and settling of trades and the holding of securities by banks, agents and depositories that are less established than those in developed countries.

*Liquidity risk* — Certain fund holdings may be or may become difficult or impossible to sell, particularly during times of market turmoil. Liquidity may be impacted by the lack of an active market for a holding, legal or contractual restrictions on resale, or the reduced number and capacity of market participants to make a market in such holding. Market prices for less liquid or illiquid holdings may be volatile or difficult to determine, and reduced liquidity may have an adverse impact on the market price of such holdings. Additionally, the sale of less liquid or illiquid holdings may involve substantial delays (including delays in settlement) and additional costs and the fund may be unable to sell such holdings when necessary to meet its liquidity needs or to try to limit losses, or may be forced to sell at a loss.

*Management* — The investment adviser to the fund actively manages the fund's investments. Consequently, the fund is subject to the risk that the methods and analyses, including models, tools and data, employed by the investment adviser in this process may be flawed or incorrect and may not produce the desired results. This could cause the fund to lose value or its investment results to lag relevant benchmarks or other funds with similar objectives.

The following are additional risks associated with investing in the fund.

*Exposure to country, region, industry or sector* — Subject to the fund's investment limitations, the fund may have significant exposure to a particular country, region, industry or sector. Such exposure may cause the fund to be more impacted by risks relating to and developments affecting the country, region, industry or sector, and thus its net asset value may be more volatile, than a fund without such

American Funds Insurance Series / Prospectus&nbsp;&nbsp;&nbsp;&nbsp; 10

------

levels of exposure. For example, if the fund has significant exposure in a particular country, then social, economic, regulatory or other issues that negatively affect that country may have a greater impact on the fund than on a fund that is more geographically diversified.

*Lending of portfolio securities —* Securities lending involves risks, including the risk that the loaned securities may not be returned in a timely manner or at all, which would interfere with the fund's ability to vote proxies or settle transactions, and/or the risk of a counterparty default. Additionally, the fund may lose money from the reinvestment of collateral received on loaned securities in investments that decline in value, default or do not perform as expected.

*Cybersecurity breaches* — The fund may be subject to operational and information security risks through breaches in cybersecurity. Cybersecurity breaches can result from deliberate attacks or unintentional events, including "ransomware" attacks, the injection of computer viruses or malicious software code, the use of vulnerabilities in code to gain unauthorized access to digital information systems, networks or devices, or external attacks such as denial-of-service attacks on the investment adviser's or an affiliate's website that could render the fund's network services unavailable to intended end-users. These breaches may, among other things, lead to the unauthorized release of confidential information, misuse of the fund's assets or sensitive information, the disruption of the fund's operational capacity, the inability of fund shareholders to transact business, or the destruction of the fund's physical infrastructure, equipment or operating systems. These events could cause the fund to violate applicable privacy and other laws and could subject the fund to reputational damage, additional costs associated with corrective measures and/or financial loss. The fund may also be subject to additional risks if its third-party service providers, such as the fund's investment adviser, transfer agent, custodian, administrators and other financial intermediaries, experience similar cybersecurity breaches and potential outcomes. Cybersecurity risks may also impact issuers of securities in which the fund invests, which may cause the fund's investments in such issuers to lose value.

*Large shareholder transactions risk* — The fund may experience adverse effects when shareholders, including other funds or accounts advised by the investment adviser, purchase or redeem, individually or in the aggregate, large amounts of shares relative to the size of the fund. For example, when the investment adviser changes allocations in other funds and accounts it manages, such changes may result in shareholder transactions in the fund that are large relative to the size of the fund. Such large shareholder redemptions may cause the fund to sell portfolio securities at times when it would not otherwise do so, which may negatively impact the fund's net asset value and liquidity. Similarly, large fund share purchases may adversely affect the fund's performance to the extent that the fund is delayed in investing new cash and is required to maintain a larger cash position than it ordinarily would. These transactions may also accelerate the realization of taxable income to shareholders if such sales of investments resulted in gains, and may also increase transaction costs. In addition, a large redemption could result in the fund's current expenses being allocated over a smaller asset base, leading to an increase in the fund's expense ratio. These risks are heightened when the fund is small.

In addition to the principal investment strategies described above, the fund has other investment practices that are described in the statement of additional information, which includes a description of other risks related to the fund's principal investment strategies and other investment practices. The fund's investment results will depend on the ability of the fund's investment adviser to navigate the risks discussed above as well as those described in the statement of additional information.

**Fund comparative indexes** — The MSCI ACWI IMI Index is a free float-adjusted market capitalization-weighted index that is designed to measure the equity market results of large, mid, and small capitalization companies in both developed and emerging markets. The index consists of more than 40 developed and emerging market country indexes. Results reflect dividends net of withholding taxes. This index is unmanaged, and its results include reinvested dividends and/or distributions but do not reflect the effect of sales charges, commissions, account fees, expenses or U.S. federal income taxes.The MSCI All Country World Small Cap Index is a free float-adjusted market capitalization-weighted index that is designed to measure equity market results of smaller capitalization companies in both developed and emerging markets.

**Portfolio holdings** A description of the fund's policies and procedures regarding disclosure of information about its portfolio holdings is available in the statement of additional information.

**EUPAC Fund** The fund's investment objective is to provide you with long-term growth of capital. While it has no present intention to do so, the fund's board may change the fund's investment objective without shareholder approval upon 60 days' written notice to shareholders.

The fund is designed for investors seeking capital appreciation and diversification through investments in common stocks and other equity-type securities (including depositary receipts), consistent with the fund's investment objective.

Investors in the fund should have a long-term perspective and be able to tolerate potentially sharp declines in value.

The following describes certain strategies that the investment adviser uses in pursuit of the fund's investment objective and the corresponding risks:

The fund invests primarily in common stocks in Europe and the Pacific Basin that the investment adviser believes have the potential for growth. Growth stocks are stocks that the investment adviser believes have the potential for above-average capital appreciation.

Normally, the fund will invest at least 80% of its net assets in securities of issuers in Europe and the Pacific Basin. This policy is subject to change only upon 60 days' notice to shareholders. A country will be considered part of Europe if it is part of the MSCI European indexes, and part of the Pacific Basin if any of its borders touches the Pacific Ocean. In determining the domicile of an issuer, the fund's investment adviser will generally look to the determination of MSCI Inc. (MSCI) for equity securities and Bloomberg for debt securities. In certain limited circumstances (including where relevant data is unavailable or the nature of a holding warrants special considerations), the adviser may also take into account additional factors, as applicable, including where the issuer's securities are listed; where the issuer is legally

organized, maintains principal corporate offices, conducts its principal operations, generates revenues and/or has credit risk exposure; and the source of guarantees, if any, of such securities. The fund may invest a portion of its assets in common stocks and other securities of companies in emerging markets.

The fund may also hold cash, cash equivalents and fixed-income securities, including commercial paper and short-term securities issued by the U.S. government, its agencies and instrumentalities. The percentage of the fund invested in such holdings varies and depends on various factors, including market conditions and purchases and redemptions of fund shares. The investment adviser may determine that it is appropriate to invest a substantial portion of the fund's assets in such instruments in response to certain circumstances, such as periods of market turmoil. For temporary defensive purposes, the fund may invest without limitation in such instruments. A larger percentage of such holdings could moderate the fund's investment results in a period of rising market prices. Alternatively, a larger percentage of such holdings could reduce the magnitude of the fund's loss in a period of falling market prices and provide liquidity to make additional investments or to meet redemptions.

The fund may invest in certain other funds managed by the investment adviser or its affiliates ("Central Funds") to more effectively invest in a diversified set of securities in a specific asset class such as money market instruments, bonds and other securities. Shares of Central Funds are only offered for purchase to the fund's investment adviser and its affiliates and other funds, investment vehicles and accounts managed by the fund's investment adviser and its affiliates. Central Funds do not charge management fees. As a result, the fund does not bear additional management fees when investing in Central Funds, but the fund does bear its proportionate share of Central Fund expenses. The investment results of the portions of the fund's assets invested in the Central Funds will be based upon the investment results of the Central Funds.

The fund may also lend portfolio securities to brokers, dealers and other institutions that provide cash or U.S. Treasury securities as collateral in an amount at least equal to the value of the securities loaned.

political, social, economic or market developments (including social instability, regional conflicts, terrorism and war) in the countries or regions in which the issuers are domiciled, operate or generate revenue or to which the securities are tied economically. These securities may also lose value due to changes in foreign currency exchange rates against the U.S. dollar and/or currencies of other countries. Issuers of these securities may be more susceptible to actions of foreign governments, such as nationalization, currency blockage or the imposition of price controls, sanctions, or punitive taxes, each of which could adversely impact the value of these securities.

For example, if the fund has significant exposure in a particular country, then social, economic, regulatory or other issues that negatively affect that country may have a greater impact on the fund than on a fund that is more geographically diversified.

*Investing in depositary receipts* — Depositary receipts are securities that evidence ownership interests in, and represent the right to receive, a security or a pool of securities that have been deposited with a bank or trust depository. Such securities may be less liquid or may trade at a lower price than the underlying securities of the issuer. Additionally, receipt of corporate information about the underlying issuer and proxy disclosure may not be timely and there may not be a correlation between such information and the market value of the depositary receipts.

*Liquidity risk* — Certain fund holdings may be or may become difficult or impossible to sell, particularly during times of market turmoil. Liquidity may be impacted by the lack of an active market for a holding, legal or contractual restrictions on resale, or the reduced number and capacity of market participants to make a market in such holding.

A discussion regarding the basis for the approval of the Series' Investment Advisory and Service Agreement by the Series' board of trustees is contained in the Series' annual or semi-annual report in Form N-CSR for the most recent fiscal period.

Capital Research and Management Company manages equity assets through three equity investment divisions and fixed income assets through its fixed income investment division, Capital Fixed Income Investors. The three equity investment divisions — Capital International Investors, Capital Research Global Investors and Capital World Investors — make investment decisions independently of one another.

The equity investment divisions may, in the future, be incorporated as wholly owned subsidiaries of Capital Research and Management Company. In that event, Capital Research and Management Company would continue to be the investment adviser, and day-to-day investment management of equity assets would continue to be carried out through one or more of these subsidiaries. Although not currently contemplated, Capital Research and Management Company could incorporate its fixed income investment division in the future and engage it to provide day-to-day investment management of fixed income assets. Capital Research and Management Company and each of the funds it advises have received an exemptive order from the U.S. Securities and Exchange Commission that allows Capital Research and Management Company to use, upon approval of the funds' boards, its management subsidiaries and affiliates to provide day-to-day investment management services to the funds, including making changes to the management subsidiaries and affiliates providing such services. The Series' shareholders approved this arrangement; however, there is no assurance that Capital Research and Management Company will incorporate its investment divisions or exercise any authority granted to it under the exemptive order.

In addition, shareholders of the Series have approved a proposal to reorganize the Series into a Delaware statutory trust. However, the Series reserved the right to delay implementing the reorganization and has elected to do so.

**The Capital System<sup>TM</sup>** Capital Research and Management Company uses a system of multiple portfolio managers in managing fund assets. Under this approach, the portfolio of a fund is divided into segments managed by individual managers. In addition, Capital Research and Management Company's investment analysts may make investment decisions with respect to a portion of each underlying fund's portfolio. Investment decisions are subject to a fund's objective(s), policies and restrictions and the oversight of the appropriate investment-related committees of Capital Research and Management Company and its investment divisions.

Certain senior members of Capital Fixed Income Investors, the investment adviser's fixed income investment division, serve on the Portfolio Strategy Group. The group utilizes a research-driven process with input from the investment adviser's analysts, portfolio managers and economists to define investment themes on a range of macroeconomic factors, including duration, yield curve and sector allocation. Where applicable, the investment decisions made by a fund's fixed income portfolio managers are informed by the investment themes discussed by the group.

Information regarding the portfolio managers' compensation, their ownership of securities in the Series and other accounts they manage is in the statement of additional information.

**Purchases and redemptions of shares** Shares of the Series are currently offered only to insurance company separate accounts as well as so-called "feeder funds" under master-feeder arrangements sponsored by insurance companies as underlying investments for such insurance companies' variable annuity contracts and variable life insurance policies. All such shares may be purchased or redeemed by the insurance company separate accounts (or feeder funds) at net asset value without any sales or redemption charges. These purchases and redemptions are made at the price next determined after such purchases and redemptions of units of the separate accounts (or feeder funds). The Series typically expects to remit redemption proceeds one business day following receipt and acceptance of a redemption order, regardless of the method the Series uses to make such payment (e.g., check, wire or automated clearing house transfer). However, payment may take longer than one business day and may take up to seven days as generally permitted by the Investment Company Act of 1940, as amended (the "1940 Act"). Under the 1940 Act, the Series may be permitted to pay redemption proceeds beyond seven days under certain limited circumstances.

Under normal conditions, the Series typically expects to meet shareholder redemptions from a reserve of highly liquid assets, such as cash or cash equivalents. The Series may use additional methods to meet shareholder redemptions, if they become necessary. These methods may include, but are not limited to, the sale of portfolio assets, the use of overdraft protection afforded by the Series' custodian bank, borrowing from a line of credit and making payment with fund securities or other fund assets rather than in cash (as further discussed in the following paragraph).

Although payment of redemptions normally will be in cash, the Series may pay the redemption price wholly or partly with portfolio securities or other fund assets under conditions and circumstances determined by the Series' board of trustees. On the same redemption date, some shareholders may be paid in whole or in part in securities (which may differ among those shareholders), while other shareholders may be paid entirely in cash. In general, in-kind redemptions to affiliated shareholders will as closely as practicable represent the affiliated shareholder's pro rata share of the Series' securities, subject to certain exceptions. Securities distributed in-kind to unaffiliated shareholders will be selected by the investment adviser in a manner the investment adviser deems to be fair and reasonable to the Series' shareholders. The disposal of the securities received in-kind may be subject to brokerage costs and, until sold, such securities remain subject to market risk and liquidity risk, including the risk that such securities are or become difficult to sell. If the Series pays your redemption with illiquid or less liquid securities, you will bear the risk of not being able to sell such securities.

**Frequent trading of fund shares** The Series and Capital Client Group, Inc., the Series' distributor, reserve the right to reject any purchase order for any reason. The funds are not designed to serve as vehicles for frequent trading. Frequent trading of fund shares may lead to increased costs to the funds and less efficient management of the funds' portfolios, potentially resulting in dilution of the value of the shares held by long-term shareholders. Accordingly, purchases, including those that are part of exchange activity, that the Series or Capital Client Group, Inc. has determined could involve actual or potential harm to a fund may be rejected.

The Series, through its transfer agent, American Funds Service Company, has agreements with the Series' insurance relationships to maintain its surveillance procedures that are designed to detect frequent trading in fund shares. The agreements generally require the insurance companies to (i) provide, upon request from a fund, the Series or their agent, certain identifying and account information regarding contract owners who invest in fund shares through an insurance company account and (ii) execute instructions from a fund, the Series or their agent to restrict further purchases or exchanges of fund shares by a contract owner who the Series has identified as having engaged in potentially harmful market timing or frequent trading. Under these procedures, various analytics are used to evaluate factors that may be indicative of frequent trading. For example, transactions in fund shares that exceed certain monetary thresholds may be scrutinized. American Funds Service Company may work with the insurance company separate accounts or feeder funds to apply their procedures that American Funds Service Company believes are reasonably designed to enforce the frequent trading policies of the Series. You should refer to disclosures provided by the insurance company with which you have a contract to determine the specific trading restrictions that apply to you.

Under the Series' frequent trading policy, certain trading activity will not be treated as frequent trading, such as:

· retirement plan contributions, loans and distributions (including hardship withdrawals) identified as such on the retirement plan recordkeeper's system;

· purchases and redemptions in community foundation accounts;

· purchase transactions involving in-kind transfers of fund shares, if the entity maintaining the contract owner's account is able to identify the transaction as one of these types of transactions;

· transactions by certain intermediaries in accordance with established hedging programs approved by the fund's investment adviser; and

· systematic redemptions and purchases if the entity maintaining the contract owner's account is able to identify the transaction as a systematic redemption or purchase.

Generally, purchases and redemptions will not be considered "systematic" unless the transaction is prescheduled for a specific date.

American Funds Service Company will monitor for other types of activity that could potentially be harmful to the Series – for example short-term trading activity in multiple funds. If American Funds Service Company identifies any activity that may constitute frequent trading, it reserves the right to contact the insurance company separate account or feeder fund and request that the separate account or feeder fund either provide information regarding an account owner's transactions or restrict the account owner's trading. If American Funds Service Company is not satisfied that insurance company separate account or feeder fund has taken appropriate action, American Funds Service Company may terminate the separate account's or feeder fund's ability to transact in fund shares.

There is no guarantee that all instances of frequent trading in fund shares will be prevented.

**Notwithstanding the Series' surveillance procedures described above, all transactions in fund shares remain subject to the right of the Series, Capital Client Group, Inc. and American Funds Service Company to restrict potentially abusive trading generally, including the types of transactions described above that will not be prevented.**

**Valuing shares** The net asset value of each share class of a fund is the value of a single share of that class. Net asset value is computed by adding a class's share of the value of a fund's investments, cash and other assets, subtracting the class's share of the fund's liabilities allocated to the class, and dividing the result by the number of shares of that class that are outstanding. Realized investment income and gain is included in the fund's net asset value until the ex-dividend date, when the declared dividend amount is treated as a fund liability. The net asset value per share is calculated once daily as of the close of regular trading on the New York Stock Exchange, normally 4 p.m. New York time, each day the New York Stock Exchange is open. If the New York Stock Exchange makes a scheduled (e.g., the day after Thanksgiving) or an unscheduled close prior to 4 p.m. New York time, the net asset value of each fund will be determined at approximately the time the New York Stock Exchange closes on that day. If on such a day market quotations and prices from third-party pricing services are not based as of the time of the early close of the New York Stock Exchange but are as of a later time (up to approximately 4 p.m. New York time), for example because the market remains open after the close of the New York Stock Exchange, those later market quotations and prices will be used in determining the funds' net asset value.

Equity securities are valued primarily on the basis of market quotations, and debt securities are valued primarily on the basis of prices from third-party pricing services due to the lack of market quotations. Futures contracts are valued primarily on the basis of settlement prices. The funds' portfolio investments are valued in accordance with procedures for making fair value determinations if market quotations are not readily available, including procedures to determine the representativeness of third-party vendor prices, or in the event market quotations or third-party vendor prices are not considered reliable. For example, if events occur between the close of markets outside the United States and the close of regular trading on the New York Stock Exchange that, in the opinion of the investment adviser, materially affect the value of any of the funds' equity securities that trade principally in those international markets, those securities will be valued in accordance with fair value procedures. Similarly, fair value procedures will be employed if an issuer defaults on its debt securities and there is no market for its securities. Use of these procedures is intended to result in more appropriate net asset values and, where applicable, to reduce potential arbitrage opportunities otherwise available to short-term investors.

Because certain of the funds may hold securities that are listed primarily on foreign exchanges that trade on weekends or days when the funds do not price their shares, the values of securities held in the funds may change on days when you will not be able to purchase or redeem fund shares.

Shares of the funds will be purchased or sold at the net asset value next determined after receipt of requests from the appropriate insurance company. Requests received by the appropriate insurance company prior to 4 p.m. New York time and communicated by the insurance company to the Series or its agent will be purchased or sold at that day's net asset value. Orders in good order received after the New York Stock Exchange closes (scheduled or unscheduled) will be processed at the net asset value (plus any applicable sales charge) calculated on the following business day.

**Plan of distribution** The Series has adopted a plan of distribution or "12b-1 plan" for Class 4 shares. Under the plan, the Series may finance activities primarily intended to sell shares, provided the categories of expenses are approved in advance by the Series' board of trustees. The plan provides for annual expenses of .25% for Class 4 shares. Amounts paid under the 12b-1 plan are used by insurance company contract issuers to cover distribution expenses and/or the expenses of certain contract owner services. The 12b-1 fees paid by the Series, as a percentage of average net assets, for the most recent fiscal year, are indicated in the prospectus in the Annual Fund Operating Expenses table for each fund. Since these fees are paid out of the Series' assets on an ongoing basis, over time they may cost you more than paying other types of sales charges or service fees and reduce the return of an investment in Class 4 shares.

**Other compensation to dealers** Capital Client Group, Inc., at its expense, provides additional compensation to insurance companies. These payments may be made, at the discretion of Capital Client Group, Inc., to insurance companies (or their affiliates) that have sold shares of the funds of the American Funds Insurance Series and American Funds as the exclusive underlying investments to their variable annuity contracts. A number of factors will be considered in determining payments, including the sales, assets, and the quality of the insurance company's relationship with Capital Client Group, Inc. The payment will typically be determined using a formula applied consistently to insurance companies based on the relevant facts and circumstances. Aggregate payments made by Capital Client Group, Inc. to insurance companies may also change from year to year. Only assets and deposits in variable annuity contracts that offer exclusively shares of the funds of the American Funds Insurance Series and American Funds are included in the formula. Further, assets for which the insurance company, or an affiliated broker-dealer, acts as an ERISA investment fiduciary are generally excluded from the formula. Capital Client Group, Inc. makes these payments to help defray the costs incurred by qualifying insurance companies in connection with efforts to educate their sales force about the American Funds Insurance Series and American Funds so that they help financial advisers make recommendations and provide services that are suitable and meet contractholders' needs. These payments may also be made to help defray the costs associated with the insurance company's provision of account-related services and activities and support the insurance company's distribution activities. Capital Client Group, Inc. will, on a periodic basis, determine the advisability of continuing these payments. As of May 1, 2026, the insurance companies (or their affiliates) that Capital Client Group, Inc. anticipates will receive additional compensation based on prior payments include Lincoln National Life Insurance Co.

Firms receiving additional compensation payments must sign a letter acknowledging the purpose of the payment and Capital Client Group, Inc.'s goal that the payment will help facilitate education of their sales force about the American Funds Insurance Series and American Funds to help financial professionals make suitable recommendations and better serve their clients who invest in the funds as underlying investments to variable annuity contracts. The letters generally require the firms to (1) offers shares of the funds of the American Funds Insurance Series and American Funds as the exclusive underlying investments to their variable annuity contracts, and (2) provide Capital Client Group, Inc. broad access to their sales force and product platforms and develop a business plan to achieve such access.

Capital Client Group, Inc. may also pay expenses associated with meetings and other training and educational opportunities conducted by insurance companies, selling dealers, advisory platform providers and other intermediaries to facilitate educating financial professionals and shareholders about the American Funds Insurance Series and American Funds. For example, some of these expenses may include, but not be limited to, meeting sponsor fees, meeting location fees, fees for data and reporting, and fees to obtain lists of financial professionals to better tailor training and education opportunities. In addition, Capital Client Group, Inc. and/or its affiliates may make payments to third parties for platform fees and other services.

If investment advisers, distributors or other affiliates of mutual funds pay additional compensation or other incentives to insurance companies in differing amounts, insurance companies and the financial professionals with which they interact may have financial incentives for recommending a particular mutual fund over other mutual funds or investments, creating a potential conflict of interest. You should consult with your financial professional and review carefully any disclosure by your financial professional's firm as to compensation received.

**Fund expenses** In periods of market volatility, assets of the funds may decline significantly, causing total annual fund operating expenses (as a percentage of the value of your investment) to become higher than the numbers shown in the Annual Fund Operating Expenses tables in this prospectus.

The "Other expenses" items in the Annual Fund Operating Expenses tables in this prospectus are based on expenses as of each fund's most recently completed fiscal year. These items include third-party expenses, such as custodial, legal, audit, accounting, regulatory reporting and pricing vendor services, and an administrative services fee payable to the Series' investment adviser for administrative services provided by the Series' investment adviser and its affiliates. In addition, the "Other expenses" items for Class 4 shares include fees for administrative services provided by the insurance companies that include Class 4 shares of any of the funds as underlying investments in their variable contracts. Each fund will pay an insurance administration fee of .25% of Class 4 share assets to these insurance companies for providing certain services pursuant to an insurance administrative services plan adopted by the Series.

For all share classes, "Other expenses" items in the Annual Fund Operating Expenses table in this prospectus include fees for administrative services provided by the fund's investment adviser and its affiliates. Administrative services are provided by the investment adviser and its affiliates to help assist third parties providing non-distribution services to fund shareholders. These services include providing in-depth information on the fund and market developments that impact fund investments. Administrative services also include, but are not limited to, coordinating, monitoring and overseeing third parties that provide services to fund shareholders.

The Administrative Services Agreement between the fund and the investment adviser provides the fund the ability to charge an administrative services fee of .05% for all share classes. The fund's investment adviser receives an administrative services fee at the annual rate of .03% of the average daily net assets of the fund attributable to all share classes (which could be increased as noted above) for its provision of administrative services.

**Investment results** All fund results in the "Investment results" section of this prospectus reflect the reinvestment of dividends and capital gains distributions, if any. Unless otherwise noted, fund results reflect any fee waivers and/or expense reimbursements in effect during the period presented.

**Distributions and taxes** Each fund of the Series intends to qualify as a "regulated investment company" under the Internal Revenue Code. In any fiscal year in which a fund so qualifies and distributes to shareholders its investment company taxable income and net realized capital gain, the fund itself is relieved of federal income tax.

It is the Series' policy to distribute to the shareholders (the insurance company separate accounts) all of its investment company taxable income and capital gain for each fiscal year.

**Financial highlights** The Financial Highlights table is intended to help you understand a fund's results for the past five fiscal years (or, if shorter, the period of operations). Certain information reflects financial results for a single share of a particular class. The total returns in the table represent the rate that an investor would have earned or lost on an investment in a fund (assuming reinvestment of all dividends and capital gain distributions). Where indicated, figures in the table reflect the impact, if any, of certain waivers from Capital Research and Management Company. For more information about these waivers, see the fund's statement of additional information and Form N-CSR. The information in the Financial Highlights table has been audited by PricewaterhouseCoopers LLP, whose current report, along with the funds' financial statements, is included in the statement of additional information, which is available upon request. Figures shown do not reflect insurance contract fees and expenses. If insurance contract fees and expenses were reflected, results would be lower.

**Certain investment limitations and guidelines**

The following limitations and guidelines are considered at the time of purchase, under normal circumstances, and are based on a percentage of each fund's net assets (excluding, for the avoidance of doubt, collateral held in connection with securities lending activities) unless otherwise noted. This summary is not intended to reflect all of the funds' investment limitations.

#### SMALLCAP World Fund
Equity securities – small capitalization issuers

· Normally the fund invests at least 80% of its net assets in common stocks and other equity-type securities (such as preferred stocks, convertible preferred stocks and convertible bonds) of companies with small market capitalizations, including growth-oriented stocks. The investment adviser currently defines "small market capitalization" companies to be companies with market capitalizations within or below the capitalization range of companies included in the MSCI All Country World Small Cap Index or the Russell 2000 Index, measured based on the maximum market capitalization of companies in either index within the last 12 months. As of August 31, 2025, the largest company in the MSCI All Country World Small Cap Index had a market capitalization of approximately $25.9 billion and the largest company in the Russell 2000 Index had a market capitalization of approximately $20.9 billion. The market capitalization of the companies included in the MSCI All Country World Small Cap Index and the Russell 2000 Index will change with market conditions. The investment adviser has periodically re-evaluated and adjusted this definition and may continue to do so in the future. The fund may continue to hold securities of a portfolio company that subsequently appreciates above the small market capitalization threshold.

Investing outside the United States

· Under normal circumstances, the fund will invest a significant portion of its assets outside the United States, including in emerging markets. (See "Investing outside the U.S." below for more information.)

· For purposes of determining whether an investment is made in a particular country or geographic region, the fund's investment adviser will generally look to the domicile of the issuer in the case of equity securities or to the country to which the security is tied economically in the case of debt securities. In doing so, the fund's investment adviser will generally look to the determination of MSCI Inc. (MSCI) for equity securities and Bloomberg for debt securities. In certain limited circumstances (including when relevant data is unavailable or the nature of a holding warrants special considerations), the adviser may also take into account additional factors, as applicable, including where the issuer's securities are listed; where the issuer is legally organized, maintains principal corporate offices, conducts its principal operations, generates revenues and/or has credit risk exposure; and the source of guarantees, if any, of such securities.

Debt instruments

· The fund may invest up to 10% of its assets in straight debt securities rated Baa1 or below and BBB+ or below by Nationally Recognized Statistical Rating Organizations designated by the fund's investment adviser, or unrated but determined to be of equivalent quality.

American Funds Insurance Series — Page 2

· The fund currently intends to consider the ratings from Moody's Investors Service, S&P Global Ratings and Fitch Ratings. If agency ratings of a security differ, the security will be considered to have received the highest of these ratings, consistent with the fund's investment policies.

 **<u>EUPAC Fund</u>** 

Investment strategies

· Normally, the fund will invest at least 80% of its net assets in securities of issuers in Europe and the Pacific Basin. This policy is subject to change only upon 60 days' written notice to shareholders. A country will be considered part of Europe if it is part of the MSCI European indexes and part of the Pacific Basin if any of its borders touches the Pacific Ocean. In determining the domicile of an issuer, the fund's investment adviser will generally look to the determination of MSCI Inc. (MSCI) for equity securities and Bloomberg for debt securities. In certain limited circumstances (including when relevant data is unavailable or the nature of a holding warrants special considerations), the adviser may also take into account additional factors, as applicable, including where the issuer's securities are listed; where the issuer is legally organized, maintains principal corporate offices, conducts its principal operations, generates revenues and/or has credit risk exposure; and the source of guarantees, if any, of such securities.

· Although the United States is considered part of the Pacific Basin, the fund will not generally purchase equity securities of issuers domiciled in the United States. However, the fund may invest up to 10% of its assets in securities of issuers domiciled in the United States (excluding cash, cash equivalents and securities held as collateral issued by U.S. issuers, which will be treated as Pacific Basin assets).

· The fund invests primarily in the common stocks located outside the United States. The fund may invest a portion of its assets in companies located in emerging markets.

Debt instruments

· The fund may invest up to 5% of its assets in straight debt securities (i.e., not convertible into equity) rated Baa1 or below and BBB+ or below by Nationally Recognized Statistical Rating Organizations or in unrated securities that are determined to be of equivalent quality by Capital Research and Management Company (the "investment adviser").

· The fund currently intends to consider the ratings from Moody's Investors Service, S&P Global Ratings and Fitch Ratings. If agency ratings of a security differ, the security will be considered to have received the highest of these ratings, consistent with the fund's investment policies.

**\* \* \* \* \* \***

The funds may experience difficulty liquidating certain portfolio securities during significant market declines or periods of heavy redemptions.

**Description of certain securities, investment techniques and risks**

The descriptions below are intended to supplement the material in the prospectus under "Investment objectives, strategies and risks." With respect to all funds, portfolio changes will be made without regard to the length of time a particular investment may have been held.

**Market conditions –** The value of, and the income generated by, the securities in which the fund invests may decline, sometimes rapidly or unpredictably, due to factors affecting certain issuers, particular industries or sectors, or the overall markets. Rapid or unexpected changes in market conditions could cause the fund to liquidate holdings at inopportune times or at a loss or depressed value. The value of a particular holding may decrease due to developments related to that issuer, but also due to general market conditions, including real or perceived economic developments such as changes in interest rates, credit quality, inflation, or currency rates or generally adverse investor sentiment, or political events, such as the imposition of trading and tariff arrangements. The value of a holding may also decline due to factors that negatively affect a particular industry or sector, such as labor shortages, increased production costs, or competitive conditions.

Global economies and financial markets are highly interconnected, and conditions and events in one country, region or financial market may adversely impact issuers in a different country, region or financial market. Furthermore, local, regional and global events such as war, acts of terrorism, trading and tariff arrangements, social unrest, natural disasters, the spread of infectious illness or other public health threats, or bank failures could also adversely impact issuers, markets and economies, including in ways that cannot necessarily be foreseen. The fund could be negatively impacted if the value of a portfolio holding were harmed by such conditions or events.

Significant market disruptions, such as those caused by pandemics, natural or environmental disasters, war, acts of terrorism, bank failures or other events, can adversely affect local and global markets and normal market operations. Market disruptions may exacerbate political, social, and economic risks. Additionally, market disruptions may result in increased market volatility; regulatory trading halts; closure of domestic or foreign exchanges, markets, or governments; or market participants operating pursuant to business continuity plans for indeterminate periods of time. Such events can be highly disruptive to economies and markets and significantly impact individual companies, sectors, industries, markets, currencies, interest and inflation rates, credit ratings, investor sentiment, and other factors affecting the value of the fund's investments and operation of the fund. These events could disrupt businesses that are integral to the fund's operations or impair the ability of employees of fund service providers to perform essential tasks on behalf of the fund.

Governmental and quasi-governmental authorities may take a number of actions designed to support local and global economies and the financial markets in response to economic disruptions. Such actions may include a variety of significant fiscal and monetary policy changes, including, for example, direct capital infusions into companies, new monetary programs and significantly lower interest rates. These actions have resulted in significant expansion of public debt and may result in greater market risk. Additionally, an unexpected or quick reversal of these policies, or the ineffectiveness of these policies, could negatively impact overall investor sentiment and further increase volatility in securities markets.

**Equity securities —** Certain funds may invest in equity securities. Equity securities represent an ownership position in a company. Equity securities held by the fund typically consist of common stocks. The prices of equity securities fluctuate based on, among other things, events specific to their issuers and market, economic and other conditions. For example, prices of these securities can be affected by financial contracts held by the issuer or third parties (such as derivatives) relating to the security or other assets or indices. Holders of equity securities are not creditors of the issuer. If an issuer liquidates, holders of equity securities are entitled to their pro rata share of the issuer's assets, if

American Funds Insurance Series — Page 4

any, after creditors (including the holders of fixed income securities and senior equity securities) are paid.

There may be little trading in the secondary market for particular equity securities, which may adversely affect the fund's ability to value accurately or dispose of such equity securities. Adverse publicity and investor perceptions, whether or not based on fundamental analysis, may decrease the value and/or liquidity of equity securities.

The growth-oriented, equity-type securities generally purchased by certain of the funds may involve large price swings and potential for loss. To the extent the fund invests in income-oriented, equity-type securities, income provided by the fund may be reduced by changes in the dividend policies of, and the capital resources available at, the companies in which the fund invests.

**Debt instruments —** Debt securities, also known as "fixed income securities," are used by issuers to borrow money. Bonds, notes, debentures, asset-backed securities (including those backed by mortgages), and loan participations and assignments are common types of debt securities. Generally, issuers pay investors periodic interest and repay the amount borrowed either periodically during the life of the security and/or at maturity. Some debt securities, such as zero coupon bonds, do not pay current interest, but are purchased at a discount from their face values and their values accrete over time to face value at maturity. Some debt securities bear interest at rates that are not fixed, but that vary with changes in specified market rates or indices. The market prices of debt securities fluctuate depending on such factors as interest rates, credit quality and maturity. In general, market prices of debt securities decline when interest rates rise and increase when interest rates fall. These fluctuations will generally be greater for longer-term debt securities than for shorter-term debt securities. Prices of these securities can also be affected by financial contracts held by the issuer or third parties (such as derivatives) relating to the security or other assets or indices. Borrowers that are in bankruptcy or restructuring may never pay off their indebtedness, or they may pay only a small fraction of the amount owed. Direct indebtedness of countries, particularly emerging markets, also involves a risk that the governmental entities responsible for the repayment of the debt may be unable, or unwilling, to pay interest and repay principal when due.

Lower rated debt securities, rated Ba1/BB+ or below by Nationally Recognized Statistical Rating Organizations, are described by the rating agencies as speculative and involve greater risk of default or price changes due to changes in the issuer's creditworthiness than higher rated debt securities, or they may already be in default. Such securities are sometimes referred to as "junk bonds" or high yield bonds. The market prices of these securities may fluctuate more than higher quality securities and may decline significantly in periods of general economic difficulty. It may be more difficult to dispose of, and to determine the value of, lower rated debt securities. Investment grade bonds in the ratings categories A or Baa/BBB also may be more susceptible to changes in market or economic conditions than bonds rated in the highest rating categories.

Certain additional risk factors relating to debt securities are discussed below:

**Sensitivity to interest rate and economic changes —** Debt securities may be sensitive to economic changes, political and corporate developments, and interest rate changes. In addition, during an economic downturn or a period of rising interest rates, issuers that are highly leveraged may experience increased financial stress that could adversely affect their ability to meet projected business goals, to obtain additional financing and to service their principal and interest payment obligations. Periods of economic change and uncertainty also can be expected to result in increased volatility of market prices and yields of certain debt securities and derivative instruments. As discussed under "Market conditions" above in this statement of additional information, governments and quasi-governmental authorities may take actions to support local and global economies and financial markets during periods of economic crisis, including direct capital infusions into companies, new monetary programs and significantly lower interest rates. Such actions may expose fixed income markets to heightened volatility and may reduce liquidity for certain investments, which could cause the value of the funds' portfolio to decline.

**Payment expectations —** Debt securities may contain redemption or call provisions. If an issuer exercises these provisions in a lower interest rate market, the funds may have to replace the security with a lower yielding security, resulting in decreased income to investors. If the issuer of a debt security defaults on its obligations to pay interest or principal or is the subject of bankruptcy proceedings, the funds may incur losses or expenses in seeking recovery of amounts owed to them.

**Liquidity and valuation —** There may be little trading in the secondary market for particular debt securities, which may affect adversely the funds' ability to value accurately or dispose of such debt securities. Adverse publicity and investor perceptions, whether or not based on fundamental analysis, may decrease the value and/or liquidity of debt securities.

Credit ratings for debt securities provided by rating agencies reflect an evaluation of the safety of principal and interest payments, not market value risk. The rating of an issuer is a rating agency's view of past and future potential developments related to the issuer and may not necessarily reflect actual outcomes. There can be a lag between the time of developments relating to an issuer and the time a rating is assigned and updated. The investment adviser considers these ratings of securities as one of many criteria in making its investment decisions.

Bond rating agencies may assign modifiers (such as +/–) to ratings categories to signify the relative position of a credit within the rating category. Investment policies that are based on ratings categories should be read to include any security within that category, without giving consideration to the modifier except where otherwise provided. See the appendix to this statement of additional information for more information about credit ratings.

**Securities with equity and debt characteristics —** Certain securities have a combination of equity and debt characteristics. Such securities may at times behave more like equity than debt or vice versa.

**Preferred stock** — Preferred stock represents an equity interest in an issuer that generally entitles the holder to receive, in preference to common stockholders and the holders of certain other stocks, dividends and a fixed share of the proceeds resulting from a liquidation of the issuer. Preferred stocks may pay fixed or adjustable rates of return, and preferred stock dividends may be cumulative or non-cumulative and participating or non-participating. Cumulative dividend provisions require all or a portion of prior unpaid dividends to be paid before dividends can be paid to the issuer's common stockholders, while prior unpaid dividends on non-cumulative preferred stock are forfeited. Participating preferred stock may be entitled to a dividend exceeding the issuer's declared dividend in certain cases, while non-participating preferred stock is entitled only to the stipulated dividend. Preferred stock is subject to issuer-specific and market risks applicable generally to equity securities. As with debt securities, the prices and yields of preferred stocks often move with changes in interest rates and the issuer's credit quality. Additionally, a company's preferred stock typically pays dividends only after the company makes required payments to holders of its bonds and other debt. Accordingly, the price of preferred stock will usually react more strongly than bonds and other debt to actual or perceived changes in the issuing company's financial condition or prospects. Preferred stock of smaller companies may be more vulnerable to adverse developments than preferred stock of larger companies.

**Convertible securities** — A convertible security is a debt obligation, preferred stock or other security that may be converted, within a specified period of time and at a stated conversion rate, into common stock or other equity securities of the same or a different issuer. The conversion may occur automatically upon the occurrence of a predetermined event or at the option of either the issuer or the security holder. Under certain circumstances, a convertible security may also be called for redemption or conversion by the issuer after a particular date and at predetermined price specified upon issue. If a convertible security held by a certain fund is called for redemption or conversion, the fund could be required to tender the security for redemption, convert it into the underlying common stock, or sell it to a third party.

The holder of a convertible security is generally entitled to participate in the capital appreciation resulting from a market price increase in the issuer's common stock and to receive interest paid or accrued until the convertible security matures or is redeemed, converted or exchanged. Before conversion, convertible securities have characteristics similar to non-convertible debt or preferred securities, as applicable. Convertible securities rank senior to common stock in an issuer's capital structure and, therefore, normally entail less risk than the issuer's common stock. However, convertible securities may also be subordinate to any senior debt obligations of the issuer, and, therefore, an issuer's convertible securities may entail more risk than such senior debt obligations. Convertible securities usually offer lower interest or dividend yields than non-convertible debt securities of similar credit quality because of the potential for capital appreciation. In addition, convertible securities are often lower-rated securities.

Because of the conversion feature, the price of a convertible security will normally fluctuate in some proportion to changes in the price of the underlying asset, and, accordingly, convertible securities are subject to risks relating to the activities of the issuer and/or general market and economic conditions. The income component of a convertible security may cushion the security against declines in the price of the underlying asset but may also cause the price of the security to fluctuate based upon changes in interest rates and the credit quality of the issuer. As with a straight fixed income security, the price of a convertible security tends to increase when interest rates decline and decrease when interest rates rise. Like the price of a common

American Funds Insurance Series — Page 7

------

stock, the price of a convertible security also tends to increase as the price of the underlying stock rises and to decrease as the price of the underlying stock declines.

**Hybrid securities** — A hybrid security is a type of security that also has equity and debt characteristics. Like equities, which have no final maturity, a hybrid security may be perpetual. On the other hand, like debt securities, a hybrid security may be callable at the option of the issuer on a date specified at issue. Additionally, like common equities, which may stop paying dividends at virtually any time without violating any contractual terms or conditions, hybrids typically allow for issuers to withhold payment of interest until a later date or to suspend coupon payments entirely without triggering an event of default. Hybrid securities are normally at the bottom of an issuer's debt capital structure because holders of an issuer's hybrid securities are structurally subordinated to the issuer's senior creditors. In bankruptcy, hybrid security holders should only get paid after all senior creditors of the issuer have been paid but before any disbursements are made to the issuer's equity holders. Accordingly, hybrid securities may be more sensitive to economic changes than more senior debt securities. Such securities may also be viewed as more equity-like by the market when the issuer or its parent company experiences financial difficulties.

Contingent convertible securities, which are also known as contingent capital securities, are a form of hybrid security that are intended to either convert into equity or have their principal written down upon the occurrence of certain trigger events. One type of contingent convertible security has characteristics designed to absorb losses, by providing that the liquidation value of the security may be adjusted downward to below the original par value or written off entirely under certain circumstances. For instance, if losses have eroded the issuer's capital level below a specified threshold, the liquidation value of the security may be reduced in whole or in part. The write-down of the security's par value may occur automatically and would not entitle holders to institute bankruptcy proceedings against the issuer. In addition, an automatic write-down could result in a reduced income rate if the dividend or interest payment associated with the security is based on the security's par value. Such securities may, but are not required to, provide for circumstances under which the liquidation value of the security may be adjusted back up to par, such as an improvement in capitalization or earnings. Another type of contingent convertible security provides for mandatory conversion of the security into common shares of the issuer under certain circumstances. The mandatory conversion might relate, for example, to the issuer's failure to maintain a capital minimum. Since the common stock of the issuer may not pay a dividend, investors in such instruments could experience reduced yields (or no yields at all) and conversion would deepen the subordination of the investor, effectively worsening the investor's standing in the case of the issuer's insolvency. An automatic write-down or conversion event with respect to a contingent convertible security will typically be triggered by a reduction in the issuer's capital level, but may also be triggered by regulatory actions, such as a change in regulatory capital requirements, or by other factors.

**Investing in smaller capitalization stocks —** Certain funds may invest in the stocks of smaller capitalization companies. Investing in smaller capitalization stocks can involve greater risk than is customarily associated with investing in stocks of larger, more established companies. For example, smaller companies often have limited product lines, limited operating histories, limited markets or financial resources, may be dependent on one or a few key persons for management and can be more susceptible to losses. Also, their securities may be less liquid or illiquid (and therefore have to be sold at a discount from current prices or sold in small lots over an extended period of time), may be followed by fewer investment research analysts and may be subject to wider price swings, thus creating a greater chance of loss than securities of larger capitalization companies. Because SMALLCAP World Fund in particular emphasizes the stocks of issuers with smaller market capitalizations (by U.S. standards), it can be expected to have more difficulty obtaining information about the issuers or valuing or disposing of its securities than if it were to concentrate on larger capitalization stocks. The funds determine relative market capitalizations using U.S. standards.

American Funds Insurance Series — Page 8

------

Accordingly, the funds' investments in certain countries outside the United States may have larger market capitalizations relative to other companies within those countries.

**Investing in private companies —** Certain funds may invest in companies that have not publicly offered their securities. Investing in private companies can involve greater risks than those associated with investing in publicly traded companies. For example, the securities of a private company may be subject to the risk that market conditions, developments within the company, investor perception, or regulatory decisions may delay or prevent the company from ultimately offering its securities to the public. Furthermore, these investments are generally considered to be illiquid until a company's public offering and are often subject to additional contractual restrictions on resale that would prevent the fund from selling their company shares for a period of time following the public offering.

Investments in private companies can offer the fund significant growth opportunities at attractive prices. However, these investments can pose greater risk, and, consequently, there is no guarantee that positive results can be achieved in the future.

***Leverage risk —*** Certain transactions of the fund may give rise to leverage. These transactions may include, among others, derivatives, future delivery contracts and when-issued, delayed delivery or forward commitment transactions. Leverage can magnify increases and decreases in the value of the fund's portfolio and cause the fund to be more volatile than if the fund had not been leveraged. As a result, the fund may be exposed to a heightened risk of loss and increased costs. Leverage may also cause the fund to sell or liquidate portfolio positions when it may not be advantageous to do so in order to satisfy its obligations or to meet the fund's applicable regulatory requirements regarding the usage of leverage.

**Investing outside the United States —** Certain funds may invest in securities of issuers domiciled outside the United States and which may be denominated in currencies other than the U.S. dollar. Securities of issuers domiciled outside the United States or with significant operations or revenues outside the United States, and securities tied economically to countries outside the United States, may lose value because of adverse political, social, economic or market developments (including social instability, regional conflicts, terrorism and war) in the countries or regions in which the issuers are domiciled, operate or generate revenue or to which the securities are tied economically. These issuers may also be more susceptible to actions of foreign governments such as the imposition of price controls, sanctions, or punitive taxes that could adversely impact the value of these securities. To the extent the fund invests in securities that are denominated in currencies other than the U.S. dollar, these securities may also lose value due to changes in foreign currency exchange rates against the U.S. dollar and/or currencies of other countries. Securities markets in certain countries may be more volatile or less liquid than those in the United States. Investments outside the United States may also be subject to different accounting practices and different regulatory, legal, auditing, financial reporting and recordkeeping standards and practices, and may be more difficult to value, than those in the United States. In addition, the value of investments outside the United States may be reduced by foreign taxes, including foreign withholding taxes on interest and dividends. Further, there may be increased risks of delayed settlement of securities purchased or sold by the fund, which could impact the liquidity of the fund's portfolio. The risks of investing outside the United States may be heightened in connection with investments in emerging markets.

Additional costs could be incurred in connection with the fund's investment activities outside the United States. Brokerage commissions may be higher outside the United States, and the fund will bear certain expenses in connection with its currency transactions. Furthermore, increased custodian costs may be associated with maintaining assets in certain jurisdictions.

**Investing in emerging markets** — Investing in emerging markets may involve risks in addition to and greater than those generally associated with investing in the securities markets of developed

American Funds Insurance Series — Page 9

------

countries. For New World Fund, investing in developing countries, the securities markets of which may be referred to as emerging markets or frontier markets, may involve similar risks, and references to "emerging markets" in this statement of additional information also refer to developing countries. For instance, emerging market countries tend to have less developed political, economic and legal systems than those in developed countries. Accordingly, the governments of these countries may be less stable and more likely to intervene in the market economy, for example, by imposing capital controls, nationalizing a company or industry, placing restrictions on foreign ownership and on withdrawing sale proceeds of securities from the country, and/or imposing punitive taxes that could adversely affect the prices of securities. Information regarding issuers in emerging markets may be limited, incomplete or inaccurate, and such issuers may not be subject to regulatory, accounting, auditing, and financial reporting and recordkeeping standards comparable to those to which issuers in more developed markets are subject. The fund's rights with respect to its investments in emerging markets, if any, will generally be governed by local law, which may make it difficult or impossible for the fund to pursue legal remedies or to obtain and enforce judgments in local courts. In addition, the economies of these countries may be dependent on relatively few industries, may have limited access to capital and may be more susceptible to changes in local and global trade conditions and downturns in the world economy. Securities markets in these countries can also be relatively small and have substantially lower trading volumes. As a result, securities issued in these countries may be more volatile and less liquid, more vulnerable to market manipulation, and more difficult to value, than securities issued in countries with more developed economies and/or markets. Less certainty with respect to security valuations may lead to additional challenges and risks in calculating the fund's net asset value. Additionally, emerging markets are more likely to experience problems with the clearing and settling of trades and the holding of securities by banks, agents and depositories that are less established than those in developed countries.

In countries where direct foreign investment is limited or prohibited, the fund may invest in operating companies based in such countries through an offshore intermediary entity that, based on contractual agreements, seeks to replicate the rights and obligations of direct equity ownership in such operating company. Because the contractual arrangements do not in fact bestow the fund with actual equity ownership in the operating company, these investment structures may limit the fund's rights as an investor and create significant additional risks. For example, local government authorities may determine that such structures do not comply with applicable laws and regulations, including those relating to restrictions on foreign ownership. In such event, the intermediary entity and/or the operating company may be subject to penalties, revocation of business and operating licenses or forfeiture of foreign ownership interests, and the fund's economic interests in the underlying operating company and its rights as an investor may not be recognized, resulting in a loss to the fund and its shareholders. In addition, exerting control through contractual arrangements may be less effective than direct equity ownership, and a company may incur substantial costs to enforce the terms of such arrangements, including those relating to the distribution of the funds among the entities. These special investment structures may also be disregarded for tax purposes by local tax authorities, resulting in increased tax liabilities, and the fund's control over – and distributions due from – such structures may be jeopardized if the individuals who hold the equity interest in such structures breach the terms of the agreements. While these structures may be widely used to circumvent limits on foreign ownership in certain jurisdictions, there is no assurance that they will be upheld by local regulatory authorities or that disputes regarding the same will be resolved consistently.

Although there is no universally accepted definition, the investment adviser generally considers an emerging market to be a market that is in the earlier stages of its industrialization cycle with a low per capita gross domestic product ("GDP") and a low market capitalization to GDP ratio relative to those in the United States and the European Union, and would include markets commonly referred to as "frontier markets." For example, the investment adviser currently expects that most countries not designated as developed markets by MSCI Inc. (MSCI) will be treated as emerging markets for equity securities, and that most countries designated as emerging markets by J.P. Morgan or, if not available,

American Funds Insurance Series — Page 10

------

Bloomberg will be treated as emerging markets for debt securities; please refer to the prospectus for New World Fund for information on the countries the fund considers to be developing countries.

**Certain risk factors related to emerging markets**

**Currency fluctuations —** Certain emerging markets' currencies have experienced and in the future may experience significant declines against the U.S. dollar. For example, if the U.S. dollar appreciates against foreign currencies, the value of the fund's emerging markets securities holdings would generally depreciate and vice versa. Further, the fund may lose money due to losses and other expenses incurred in converting various currencies to purchase and sell securities valued in currencies other than the U.S. dollar, as well as from currency restrictions, exchange control regulation, governmental restrictions that limit or otherwise delay the fund's ability to convert or repatriate currencies and currency devaluations.

**Government regulation —** Certain emerging markets lack uniform accounting, auditing and financial reporting and disclosure standards, have less governmental supervision of financial markets than in the United States, and may not honor legal rights or protections enjoyed by investors in the United States. Certain governments may be more unstable and present greater risks of nationalization or restrictions on foreign ownership of local companies. Repatriation of investment income, capital and the proceeds of sales by foreign investors may require governmental registration and/or approval in some emerging markets. While the fund will only invest in markets where these restrictions are considered acceptable by the investment adviser, a country could impose new or additional repatriation restrictions after the fund's investment. If this happened, the fund's response might include, among other things, applying to the appropriate authorities for a waiver of the restrictions or engaging in transactions in other markets designed to offset the risks of decline in that country. Such restrictions will be considered in relation to the fund's liquidity needs and other factors. Further, some attractive equity securities may not be available to the fund if foreign shareholders already hold the maximum amount legally permissible.

While government involvement in the private sector varies in degree among emerging markets, such involvement may in some cases include government ownership of companies in certain sectors, wage and price controls or imposition of trade barriers and other protectionist measures. With respect to any emerging market, there is no guarantee that some future economic or political crisis will not lead to price controls, forced mergers of companies, expropriation, or creation of government monopolies to the possible detriment of the fund's investments.

**Fluctuations in inflation rates —** Rapid fluctuations in inflation rates may have negative impacts on the economies and securities markets of certain emerging market countries.

**Less developed securities markets —** Emerging markets may be less well-developed and regulated than other markets. These markets have lower trading volumes than the securities markets of more developed countries and may be unable to respond effectively to increases in trading volume. Consequently, these markets may be substantially less liquid than those of more developed countries, and the securities of issuers located in these markets may have limited marketability. These factors may make prompt liquidation of substantial portfolio holdings difficult or impossible at times.

**Settlement risks —** Settlement systems in emerging markets are generally less well organized than those of developed markets. Supervisory authorities may also be unable to apply standards comparable to those in developed markets. Thus, there may be risks that settlement may be delayed and that cash or securities belonging to the fund may be in jeopardy because

American Funds Insurance Series — Page 11

------

of failures of or defects in the systems. In particular, market practice may require that payment be made before receipt of the security being purchased or that delivery of a security be made before payment is received. In such cases, default by a broker or bank (the "counterparty") through which the transaction is effected might cause the fund to suffer a loss. The fund will seek, where possible, to use counterparties whose financial status is such that this risk is reduced. However, there can be no certainty that the fund will be successful in eliminating this risk, particularly as counterparties operating in emerging markets frequently lack the standing or financial resources of those in developed countries. There may also be a danger that, because of uncertainties in the operation of settlement systems in individual markets, competing claims may arise with respect to securities held by or to be transferred to the fund.

**Limited market information —** The fund may encounter problems assessing investment opportunities in certain emerging markets in light of limitations on available information and different accounting, auditing and financial reporting standards. For example, due to jurisdictional limitations, the Public Company Accounting Oversight Board ("PCAOB"), which regulates auditors of U.S. reporting companies, may be unable to inspect the audit work and practices of PCAOB-registered auditing firms in certain emerging markets. As a result, there is greater risk that financial records and information relating to an issuer's operations in emerging markets will be incomplete or misleading, which may negatively impact the fund's investments in such company. When faced with limited market information, the fund's investment adviser will seek alternative sources of information, and to the extent the investment adviser is not satisfied with the sufficiency or accuracy of the information obtained with respect to a particular market or security, the fund will not invest in such market or security.

**Taxation —** Taxation of dividends, interest and capital gains received by the fund varies among emerging markets and, in some cases, is comparatively high. In addition, emerging markets typically have less well-defined tax laws and procedures and such laws may permit retroactive taxation so that the fund could become subject in the future to local tax liability that it had not reasonably anticipated in conducting its investment activities or valuing its assets.

**Fraudulent securities —** Securities purchased by the fund may subsequently be found to be fraudulent or counterfeit, resulting in a loss to the fund.

**Remedies —** Emerging markets may offer less protection to investors than U.S. markets and, in the event of investor harm, there may be substantially less recourse available to the fund and its shareholders. In addition, as a matter of law or practicality, the fund and its shareholders - as well as U.S. regulators - may encounter substantial difficulties in obtaining and enforcing judgments and other actions against non-U.S. individuals and companies.

**Investing through Stock Connect —** The fund may invest in China A-shares of certain Chinese companies listed and traded on the Shanghai Stock Exchange ("SSE") and on the Shenzhen Stock Exchange ("SZSE", and together, the "Exchanges") through the Shanghai-Hong Kong Stock Connect Program and the Shenzhen-Hong Kong Stock Connect Program, respectively (together, "Stock Connect"). Stock Connect is a securities trading and clearing program developed by the Exchange of Hong Kong, the Exchanges and the China Securities Depository and Clearing Corporation Limited. Stock Connect facilitates foreign investment in the People's Republic of China ("PRC") via brokers in Hong Kong. Persons investing through Stock Connect are subject to PRC regulations and Exchange listing rules, among others. These could include limitations on or suspension of trading. These regulations are relatively new and subject to changes which could adversely impact the fund's rights with respect to the securities. For example, a stock may be recalled from the scope of securities traded on the SSE or SZSE eligible for trading via Stock Connect for various reasons, and in such event the stock can be sold but is restricted from being bought. In such event, the investment adviser's ability to implement the fund's investment strategies may be adversely affected. As Stock Connect is still

American Funds Insurance Series — Page 12

------

relatively new, investments made through Stock Connect are subject to relatively new trading, clearance and settlement procedures and there are no assurances that the necessary systems to run the program will function properly. In addition, Stock Connect is subject to aggregate and daily quota limitations on purchases and permitted price fluctuations. As a result, the fund may experience delays in transacting via Stock Connect and there can be no assurance that a liquid market on the Exchanges will exist. Since Stock Connect only operates on days when both the Chinese and Hong Kong markets are open for trading, and banking services are available in both markets on the corresponding settlement days, the fund's ownership interest in securities traded through Stock Connect may not be reflected directly and the fund may be subject to the risk of price fluctuations in China A-shares when Stock Connect is not open to trading. Changes in Chinese tax rules may also adversely affect the fund's performance. The fund's shares are held in an omnibus account and registered in nominee name. Please also see the sections on risks relating to investing outside the United States and investing in emerging markets.

**Investing through Bond Connect —** The fund may invest in onshore China bonds via Bond Connect, the opening up of China's Interbank Bond Market (CIBM) to global investors through the China-Hong Kong mutual access program. The program allows foreign and mainland China investors the ability to trade in each other's bond market through a connection between the mainland and Hong Kong based financial infrastructure institutions. Bond Connect aims to enhance the efficiency and flexibility of investing in the CIBM. This is accomplished by easing the access requirements to enter the market and using the Hong Kong trading infrastructure to connect to China Foreign Exchange Trading System (CFETS). Market volatility and potential lack of liquidity due to low trading volume of certain debt securities in CIBM may result in prices of certain debt securities traded on such market fluctuating significantly. The bid and offer spreads of the prices of such securities may be large, and the fund may therefore incur significant trading, settlement and realization costs and may face counterparty default, liquidity, and volatility risks, resulting in significant losses for the funds and their investors. Bond Connect is a novel concept and, as such, the current regulations are untested and there is no certainty as to how they will be applied. In addition, the current regulations are subject to change which may have potential retrospective effects and there can be no assurance that Bond Connect will not be abolished. New regulations may be issued from time to time by the regulators in the PRC and Hong Kong in connection with operations, legal enforcement and cross-border trades under Bond Connect. The fund may be adversely affected as a result of such changes.

**Synthetic local access instruments** — Participation notes, market access warrants and other similar structured investment vehicles (collectively, "synthetic local access instruments") are instruments used by investors to obtain exposure to equity investments in local markets where direct ownership by foreign investors is not permitted or is otherwise restricted by local law. Synthetic local access instruments, which are generally structured and sold over-the-counter by a local branch of a bank or broker-dealer that is permitted to purchase equity securities in the local market, are designed to replicate exposure to one or more underlying equity securities. The price and performance of a synthetic local access instrument are normally intended to track the price and performance of the underlying equity assets as closely as possible. However, there can be no assurance that the results of synthetic local access instruments will replicate exactly the performance of the underlying securities due to transaction costs, taxes and other fees and expenses. The holder of a synthetic local access instrument may also be entitled to receive any dividends paid in connection with the underlying equity assets, but usually does not receive voting rights as it would if such holder directly owned the underlying assets.

Investments in synthetic local access instruments involve the same risks associated with a direct investment in the shares of the companies the instruments seek to replicate, including, in particular, the risks associated with investing outside the United States. Synthetic local access instruments also involve risks that are in addition to the risks normally associated with a direct investment in the underlying equity securities. For instance, synthetic local access instruments represent unsecured, unsubordinated contractual obligations of the banks or broker-dealers that issue them. Consequently,

American Funds Insurance Series — Page 13

------

a purchaser of a synthetic local access instrument relies on the creditworthiness of such a bank or broker-dealer counterparty and has no rights under the instrument against the issuer of the underlying equity securities. Additionally, there is no guarantee that a liquid market for a synthetic local access instrument will exist or that the issuer of the instrument will be willing to repurchase the instrument when an investor wishes to sell it.

**Currency transactions —** Certain funds may enter into currency transactions on a spot (i.e., cash) basis at the prevailing rate in the currency exchange market to provide for the purchase or sale of a currency needed to purchase a security denominated in such currency. In addition, certain funds may enter into forward currency contracts and may purchase and sell options on currencies to protect against changes in currency exchange rates, to increase exposure to a particular foreign currency, to shift exposure to currency fluctuations from one currency to another or to seek to increase returns. A forward currency contract is an obligation to purchase or sell a specific currency at a future date, which may be any fixed number of days from the date of the contract agreed upon by the parties, at a price set at the time of the contract. Some forward currency contracts, called non-deliverable forwards or NDFs, do not call for physical delivery of the currency and are instead settled through cash payments. Forward currency contracts are typically privately negotiated and traded in the interbank market between large commercial banks (or other currency traders) and their customers. Although forward contracts entered into by the fund will typically involve the purchase or sale of a currency against the U.S. dollar, the fund also may purchase or sell a non-U.S. currency against another non-U.S. currency.

The fund may also purchase or write put and call options on foreign currencies on exchanges or in the over-the-counter ("OTC") market. A put option on a foreign currency gives the purchaser of the option the right to sell a foreign currency at the exercise price until the option expires. A call option on a foreign currency gives the purchaser of the option the right to purchase the currency at the exercise price until the option expires. Currency options, to the extent not exercised, will expire and the fund, as the purchaser, would experience a loss to the extent of the premium paid for the option. Instead of purchasing a call option to hedge against an anticipated increase in the dollar cost of securities to be acquired, the fund could write a put option on the relevant currency, which, if exchange rates move in the manner projected, will expire unexercised and allow the fund to hedge such increased cost up to the amount of the premium. As in the case of other types of options, however, writing a currency option will provide a hedge only up to the amount of the premium, and only if exchange rates move in the expected direction. If this does not occur, the option may be exercised and the fund would be required to purchase or sell the underlying currency at a loss that may not be offset by the amount of the premium. Through the writing of options on foreign currencies, the fund also may be required to forego all or a portion of the benefit that might otherwise have been obtained from favorable movements in exchange rates. OTC options are bilateral contracts that are individually negotiated and they are generally less liquid than exchange-traded options. Although this type of arrangement allows the purchaser or writer greater flexibility to tailor an option to its needs, OTC options generally involve credit risk to the counterparty, whereas for exchange-traded options, credit risk is mutualized through the involvement of the applicable clearing house. Currency options traded on exchanges may be subject to position limits, which may limit the ability of the fund to reduce currency risk using such options. To the extent that the U.S. options markets are closed while the markets for the underlying currencies remain open, substantial price and rate movements may take place in the currency markets that cannot be reflected in the U.S. options markets. See also "Options" for a general description of investment techniques and risks relating to options.

Currency exchange rates generally are determined by forces of supply and demand in the foreign exchange markets and the relative merits of investment in different countries as viewed from an international perspective. Currency exchange rates, as well as foreign currency transactions, can also be affected unpredictably by intervention by U.S. or foreign governments or central banks or by currency controls or political developments in the United States or abroad. Such intervention or other events could prevent the fund from entering into foreign currency transactions, force the fund to exit

such transactions at an unfavorable time or price or result in penalties to the fund, any of which may result in losses to the fund.

Generally, a fund will not attempt to protect against all potential changes in exchange rates and the use of forward contracts does not eliminate the risk of fluctuations in the prices of the underlying securities. If the value of the underlying securities declines or the amount of the fund's commitment increases because of changes in exchange rates, the fund may need to provide additional cash or securities to satisfy its commitment under the forward contract. The fund is also subject to the risk that it may be delayed or prevented from obtaining payments owed to it under the forward contract as a result of the insolvency or bankruptcy of the counterparty with which it entered into the forward contract or the failure of the counterparty to comply with the terms of the contract.

The realization of gains or losses on foreign currency transactions will usually be a function of the investment adviser's ability to accurately estimate currency market movements. Entering into forward currency transactions may change the fund's exposure to currency exchange rates and could result in losses to the fund if currencies do not perform as expected by the fund's investment adviser. For example, if the fund's investment adviser increases a fund's exposure to a foreign currency using forward contracts and that foreign currency's value declines, the fund may incur a loss. In addition, while entering into forward currency transactions could minimize the risk of loss due to a decline in the value of the hedged currency, it could also limit any potential gain that may result from an increase in the value of the currency. See also the "Derivatives" section under "Description of certain securities, investment techniques and risks" for a general description of investment techniques and risks relating to derivatives, including certain currency forwards and currency options.

Forward currency contracts may give rise to leverage, or exposure to potential gains and losses in excess of the initial amount invested. Leverage magnifies gains and losses and could cause a fund to be subject to more volatility than if it had not been leveraged, thereby resulting in a heightened risk of loss. Forward currency contracts are considered derivatives. Accordingly, under the SEC's rule applicable to the fund's use of derivatives, a fund's obligations with respect to these instruments will depend on the fund's aggregate usage of and exposure to derivatives, and the fund's usage of forward currency contracts is subject to written policies and procedures reasonably designed to manage the fund's derivatives risk.

Forward currency transactions also may affect the character and timing of income, gain, or loss recognized by the fund for U.S. tax purposes. The use of forward currency contracts could result in the application of the mark-to-market provisions of the Internal Revenue Code of 1986, as amended (the "Code") and may cause an increase (or decrease) in the amount of taxable dividends paid by the fund.

**Indirect exposure to cryptocurrencies –** Cryptocurrencies are digital assets which may act as a store of wealth, a medium of exchange or an investment asset. There are thousands of cryptocurrencies, such as bitcoin. Although the fund has no current intention of directly investing in cryptocurrencies, some issuers accept cryptocurrency for payment of services, use cryptocurrencies as reserve assets and/or invest in cryptocurrencies, and certain funds may have exposure to cryptocurrencies through investments in securities of such issuers. Certain funds may also invest in securities of issuers which provide cryptocurrency-related services.

Cryptocurrencies are subject to fluctuations in value. Cryptocurrencies are not backed by any government, corporation or other identified body. Rather, the value of a cryptocurrency is determined by other factors, such as the perceived future prospects or the supply and demand for such cryptocurrency in the global market for the trading of cryptocurrency. Cryptocurrencies may trade on platforms which are largely unregulated and may be more exposed to operational or technical issues as well as fraud or manipulation in comparison to established, regulated exchanges for securities, derivatives and traditional currencies. The values of cryptocurrencies have been, and may in the future

American Funds Insurance Series — Page 15

------

continue to be, highly volatile and subject to sudden and significant increases and declines. The value of a cryptocurrency may decline precipitously (including to zero) for a variety of reasons, including, but not limited to, regulatory changes, a loss of confidence in its network or a change in user preference to other cryptocurrencies. The value of securities of issuers with significant holdings of cryptocurrencies may be subject to, among other things, fluctuations in the value of such cryptocurrencies, and such issuers may experience custody issues and/or lose their cryptocurrency holdings through theft, hacking, or technical glitches in the applicable blockchain. Certain funds may experience losses as a result of the decline in value of its securities of issuers that own cryptocurrencies or which provide cryptocurrency-related services. If an issuer that owns cryptocurrencies intends to pay a dividend using such holdings or to otherwise make a distribution of such holdings to its stockholders, such dividends or distributions may face regulatory, operational and technical issues.

Factors affecting the further development, use, and exchange of cryptocurrency include, but are not limited to: continued worldwide growth of, or possible cessation of or reversal in, the adoption and use of cryptocurrencies and other digital assets; the developing regulatory environment relating to cryptocurrencies, including the characterization of cryptocurrencies as currencies, commodities, or securities, the tax treatment of cryptocurrencies, and government and quasi-government regulation or restrictions on, or regulation of access to and operation of, cryptocurrency networks and the exchanges on which cryptocurrencies trade, including anti-money laundering regulations and requirements; perceptions regarding the environmental impact of a cryptocurrency; changes in consumer demographics and public preferences; general economic conditions; maintenance and development of open-source software protocols; the availability and popularity of other forms or methods of buying and selling goods and services; the use of the networks supporting digital assets, such as those for developing smart contracts and distributed applications; and general risks tied to the use of information technologies, including cyber risks. A hack or failure of one cryptocurrency may lead to a loss in confidence in, and thus decreased usage and/or value of, other cryptocurrencies.

**Forward commitment, when issued and delayed delivery transactions —** Certain funds may enter into commitments to purchase or sell securities at a future date. When a fund agrees to purchase such securities, it assumes the risk of any decline in value of the security from the date of the agreement, and when a fund agrees to sell such securities, it assumes the risk of any increase in value of the security. If the other party to such a transaction fails to deliver or pay for the securities, the fund could miss a favorable price or yield opportunity, or could experience a loss.

Certain funds may roll such transactions in lieu of taking physical delivery of the contract's underlying assets on the settlement date. When rolling the purchase of these types of transactions, a fund sells mortgage-backed securities for delivery in the current month and simultaneously contracts to repurchase substantially similar (same type, coupon, and maturity) securities on a specified future date, at a pre-determined price. When rolling the sale of these types of transactions, a fund purchases mortgage-backed securities for delivery in the current month and simultaneously contracts to sell substantially similar (same type, coupon, and maturity) securities on a specified future date, at a pre-determined price.

When rolling these types of transactions, during the period between the initial sale (or purchase) and subsequent repurchase (or sale) (the "roll period"), a fund forgoes principal and interest paid on the mortgage-backed securities. The fund is compensated by the price differential between the original and new contracts (often referred to as the "drop"), if any, as well as by the interest earned on the cash proceeds of any sales. The fund also takes the risk that market prices or characteristics of the underlying mortgage-backed securities may move unfavorably between the original and new contracts. The fund could suffer a loss if the contracting party fails to perform the future transaction and a fund is therefore unable to buy or sell back the mortgage-backed securities it initially either sold or purchased, respectively. These transactions are accounted for as purchase and sale transactions, which contribute to a fund's portfolio turnover rate.

American Funds Insurance Series — Page 16

------

With to be announced ("TBA") transactions, the particular securities (i.e., specified mortgage pools) to be delivered or received are not identified at the trade date, but are "to be announced" at a later settlement date. However, securities to be delivered must meet specified criteria, including face value, coupon rate and maturity, and be within industry-accepted "good delivery" standards. The fund will not use these transactions for the purpose of leveraging. Although these transactions will not be entered into for leveraging purposes, a fund temporarily could be in a leveraged position (because it may have an amount greater than its net assets subject to market risk). Should market values of a fund's portfolio securities decline while a fund is in a leveraged position, greater depreciation of its net assets would likely occur than if it were not in such a position. After a transaction is entered into, a fund may still dispose of or renegotiate the transaction. Additionally, prior to receiving delivery of securities as part of a transaction, a fund may sell such securities.

When a fund enters into a TBA commitment for the sale of mortgage-backed securities for a fixed price, with payment and delivery on an agreed upon future settlement date (which may be referred to as having a short position in such TBA securities), a fund may or may not hold the types of mortgage-backed securities required to be delivered. To the extent a fund has sold such a security on a when-issued, delayed delivery, or forward commitment basis, a fund would not participate in future gains or losses with respect to the security if a fund holds such security. If the other party to a transaction fails to pay for the securities, a fund could suffer a loss. Additionally, when selling a security on a when-issued, delayed delivery or forward commitment basis without owning the security, a fund will incur a loss if the security's price appreciates in value such that the security's price is above the agreed-upon price on the settlement date.

Under the SEC's rule applicable to the fund's use of derivatives, when issued, forward-settling and nonstandard settlement cycle securities, as well as TBAs and roll transactions, will be treated as derivatives unless the fund intends to physically settle these transactions and the transactions will settle within 35 days of their respective trade dates.

**Obligations backed by the "full faith and credit" of the U.S. government —** U.S. government obligations include the following types of securities:

**U.S. Treasury securities —** U.S. Treasury securities include direct obligations of the U.S. Treasury, such as Treasury bills, notes and bonds. For these securities, the payment of principal and interest is unconditionally guaranteed by the U.S. government, and thus they are of high credit quality.

**Federal agency securities —** The securities of certain U.S. government agencies and government-sponsored entities are guaranteed as to the timely payment of principal and interest by the full faith and credit of the U.S. government. Such agencies and entities include, but are not limited to, the Federal Financing Bank ("FFB"), the Government National Mortgage Association ("Ginnie Mae"), the U.S. Department of Veterans Affairs ("VA"), the Federal Housing Administration ("FHA"), the Export-Import Bank of the United States ("Exim Bank"), the U.S. International Development Finance Corporation ("DFC"), the Commodity Credit Corporation ("CCC") and the U.S. Small Business Administration ("SBA").

Such securities are subject to variations in market value due to fluctuations in interest rates and in government policies, among other things, but, if held to maturity, are expected to be paid in full (either at maturity or thereafter). However, from time to time, a high national debt level, and uncertainty regarding negotiations to increase the U.S. government's debt ceiling and periodic legislation to fund the government, could increase the risk that the U.S. government may default on its obligations and/or lead to a downgrade of the credit rating of the U.S. government. Such an event could adversely affect the value of investments in securities backed by the full faith and credit of the U.S. government, cause the fund to suffer losses and lead to significant disruptions in U.S. and global markets. Regulatory or

American Funds Insurance Series — Page 17

------

market changes or conditions could increase demand for U.S. government securities and affect the availability of such instruments for investment and the fund's ability to pursue its investment strategies.

**Other federal agency obligations —** Additional federal agency securities are neither direct obligations of, nor guaranteed by, the U.S. government. These obligations include securities issued by certain U.S. government agencies and government-sponsored entities. However, they generally involve some form of federal sponsorship: some operate under a congressional charter; some are backed by collateral consisting of "full faith and credit" obligations as described above; some are supported by the issuer's right to borrow from the Treasury; and others are supported only by the credit of the issuing government agency or entity. These agencies and entities include, but are not limited to: the Federal Home Loan Banks, the Federal Home Loan Mortgage Corporation ("Freddie Mac"), the Federal National Mortgage Association ("Fannie Mae"), the Tennessee Valley Authority and the Federal Farm Credit Bank System.

In 2008, Freddie Mac and Fannie Mae were placed into conservatorship by their new regulator, the Federal Housing Finance Agency ("FHFA"). Simultaneously, the U.S. Treasury made a commitment of indefinite duration to maintain the positive net worth of both firms. As conservator, the FHFA has the authority to repudiate any contract either firm has entered into prior to the FHFA's appointment as conservator (or receiver should either firm go into default) if the FHFA, in its sole discretion determines that performance of the contract is burdensome and repudiation would promote the orderly administration of Fannie Mae's or Freddie Mac's affairs. While the FHFA has indicated that it does not intend to repudiate the guaranty obligations of either entity, doing so could adversely affect holders of their mortgage-backed securities. For example, if a contract were repudiated, the liability for any direct compensatory damages would accrue to the entity's conservatorship estate and could only be satisfied to the extent the estate had available assets. As a result, if interest payments on Fannie Mae or Freddie Mac mortgage-backed securities held by the fund were reduced because underlying borrowers failed to make payments or such payments were not advanced by a loan servicer, the fund's only recourse might be against the conservatorship estate, which might not have sufficient assets to offset any shortfalls.

The FHFA, in its capacity as conservator, has the power to transfer or sell any asset or liability of Fannie Mae or Freddie Mac. The FHFA has indicated it has no current intention to do this; however, should it do so a holder of a Fannie Mae or Freddie Mac mortgage-backed security would have to rely on another party for satisfaction of the guaranty obligations and would be exposed to the credit risk of that party.

Certain rights provided to holders of mortgage-backed securities issued by Fannie Mae or Freddie Mac under their operative documents may not be enforceable against the FHFA, or enforcement may be delayed during the course of the conservatorship or any future receivership. For example, the operative documents may provide that upon the occurrence of an event of default by Fannie Mae or Freddie Mac, holders of a requisite percentage of the mortgage-backed security may replace the entity as trustee. However, under the Federal Housing Finance Regulatory Reform Act of 2008, holders may not enforce this right if the event of default arises solely because a conservator or receiver has been appointed.

**Pass-through securities —** Certain funds may invest in various debt obligations backed by pools of mortgages, corporate loans or other assets including, but not limited to, residential mortgage loans, home equity loans, mortgages on commercial buildings, consumer loans and equipment leases. Principal and interest payments made on the underlying asset pools backing these obligations are typically passed through to investors, net of any fees paid to any insurer or any guarantor of the securities. Pass-through securities may have either fixed or adjustable coupons. The risks of an investment in these obligations depend in part on the type of the collateral securing the obligations and the class of the instrument in which the fund invests. These securities include:

American Funds Insurance Series — Page 18

**Mortgage-backed securities —** These securities may be issued by U.S. government agencies and government-sponsored entities, such as Ginnie Mae, Fannie Mae and Freddie Mac, and by private entities. The payment of interest and principal on mortgage-backed obligations issued by U.S. government agencies may be guaranteed by the full faith and credit of the U.S. government (in the case of Ginnie Mae), or may be guaranteed by the issuer (in the case of Fannie Mae and Freddie Mac). However, these guarantees do not apply to the market prices and yields of these securities, which vary with changes in interest rates.

Mortgage-backed securities issued by private entities are structured similarly to those issued by U.S. government agencies. However, these securities and the underlying mortgages are not guaranteed by any government agencies and the underlying mortgages are not subject to the same underwriting requirements. These securities generally are structured with one or more types of credit enhancements such as insurance or letters of credit issued by private companies. Borrowers on the underlying mortgages are usually permitted to prepay their underlying mortgages. Prepayments can alter the effective maturity of these instruments. In addition, delinquencies, losses or defaults by borrowers can adversely affect the prices and volatility of these securities. Such delinquencies and losses can be exacerbated by declining or flattening housing and property values. This, along with other outside pressures, such as bankruptcies and financial difficulties experienced by mortgage loan originators, decreased investor demand for mortgage loans and mortgage-related securities and increased investor demand for yield, can adversely affect the value and liquidity of mortgage-backed securities.

**Adjustable rate mortgage-backed securities —** Adjustable rate mortgage-backed securities ("ARMS") have interest rates that reset at periodic intervals. Acquiring ARMS permits the fund to participate in increases in prevailing current interest rates through periodic adjustments in the coupons of mortgages underlying the pool on which ARMS are based. Such ARMS generally have higher current yield and lower price fluctuations than is the case with more traditional fixed income debt securities of comparable rating and maturity. In addition, when prepayments of principal are made on the underlying mortgages during periods of rising interest rates, the fund can reinvest the proceeds of such prepayments at rates higher than those at which they were previously invested. Mortgages underlying most ARMS, however, have limits on the allowable annual or lifetime increases that can be made in the interest rate that the mortgagor pays. Therefore, if current interest rates rise above such limits over the period of the limitation, the fund, when holding an ARMS, does not benefit from further increases in interest rates. Moreover, when interest rates are in excess of coupon rates (i.e., the rates being paid by mortgagors) of the mortgages, ARMS behave more like fixed income securities and less like adjustable rate securities and are subject to the risks associated with fixed income securities. In addition, during periods of rising interest rates, increases in the coupon rate of adjustable rate mortgages generally lag current market interest rates slightly, thereby creating the potential for capital depreciation on such securities.

**Collateralized mortgage obligations (CMOs) —** CMOs are also backed by a pool of mortgages or mortgage loans, which are divided into two or more separate bond issues. CMOs issued by U.S. government agencies are backed by agency mortgages, while privately issued CMOs may be backed by either government agency mortgages or private mortgages. Payments of principal and interest are passed through to each bond issue at varying schedules resulting in bonds with different coupons, effective maturities and sensitivities to interest rates. Some CMOs may be structured in a way that when interest rates change, the impact of changing prepayment rates on the effective maturities of certain issues of these securities is magnified. CMOs may be less liquid or may exhibit greater price volatility than other types of mortgage or asset-backed securities.

**Commercial mortgage-backed securities —** These securities are backed by mortgages on commercial property, such as hotels, office buildings, retail stores, hospitals and other

American Funds Insurance Series — Page 19

------

commercial buildings. These securities may have a lower prepayment uncertainty than other mortgage-related securities because commercial mortgage loans generally prohibit or impose penalties on prepayments of principal. In addition, commercial mortgage-related securities often are structured with some form of credit enhancement to protect against potential losses on the underlying mortgage loans. Many of the risks of investing in commercial mortgage-backed securities reflect the risks of investing in the real estate securing the underlying mortgage loans, including the effects of local and other economic conditions on real estate markets, the ability of tenants to make rental payments and the ability of a property to attract and retain tenants. Commercial mortgage-backed securities may be less liquid or exhibit greater price volatility than other types of mortgage or asset-backed securities and may be more difficult to value.

**Asset-backed securities —** These securities are backed by other assets such as credit card, automobile or consumer loan receivables, retail installment loans or participations in pools of leases. Credit support for these securities may be based on the underlying assets and/or provided through credit enhancements by a third party. The values of these securities are sensitive to changes in the credit quality of the underlying collateral, the credit strength of the credit enhancement, changes in interest rates and at times the financial condition of the issuer. Obligors of the underlying assets also may make prepayments that can change effective maturities of the asset-backed securities. These securities may be less liquid and more difficult to value than other securities.

**Collateralized bond obligations (CBOs) and collateralized loan obligations (CLOs)** — A CBO is a trust typically backed by a diversified pool of fixed-income securities, which may include high risk, lower rated securities. A CLO is a trust typically collateralized by a pool of loans, which may include, among others, senior secured loans, senior unsecured loans, and subordinate corporate loans, including lower rated loans. CBOs and CLOs may charge management fees and administrative expenses.

For both CBOs and CLOs, the cash flows from the trust are split into two or more portions, called tranches, varying in risk and yield. The riskiest and highest yielding portion is the "equity" tranche which bears the bulk of any default by the bonds or loans in the trust and is constructed to protect the other, more senior tranches from default. Since they are partially protected from defaults, the more senior tranches typically have higher ratings and lower yields than the underlying securities in the trust and can be rated investment grade. Despite the protection from the equity tranche, the more senior tranches can still experience substantial losses due to actual defaults of the underlying assets, increased sensitivity to defaults due to impairment of the collateral or the more junior tranches, market anticipation of defaults, as well as potential general aversions to CBO or CLO securities as a class. Normally, these securities are privately offered and sold, and thus, are not registered under the securities laws. CBOs and CLOs may be less liquid, may exhibit greater price volatility and may be more difficult to value than other securities.

"IOs" and "POs" are issued in portions or tranches with varying maturities and characteristics. Some tranches may only receive the interest paid on the underlying mortgages (IOs) and others may only receive the principal payments (POs). The values of IOs and POs are extremely sensitive to interest rate fluctuations and prepayment rates, and IOs are also subject to the risk of early repayment of the underlying mortgages that will substantially reduce or eliminate interest payments.

**Warrants and rights —** Warrants and rights may be acquired by certain funds in connection with other securities or separately. Warrants generally entitle, but do not obligate, their holder to purchase other equity or fixed income securities at a specified price at a later date. Rights are similar to warrants but typically have a shorter duration and are issued by a company to existing holders of its stock to provide those holders the right to purchase additional shares of stock at a later date. Warrants and rights do

American Funds Insurance Series — Page 20

------

not carry with them the right to dividends or voting rights with respect to the securities that they entitle their holder to purchase, and they do not represent any rights in the assets of the issuing company. Additionally, a warrant or right ceases to have value if it is not exercised prior to its expiration date. As a result, warrants and rights may be considered more speculative than certain other types of investments. Changes in the value of a warrant or right do not necessarily correspond to changes in the value of its underlying security. The price of a warrant or right may be more volatile than the price of its underlying security, and they therefore present greater potential for capital appreciation and capital loss. The effective price paid for warrants or rights added to the subscription price of the related security may exceed the value of the subscribed security's market price, such as when there is no movement in the price of the underlying security. The market for warrants or rights may be very limited and it may be difficult to sell them promptly at an acceptable price.

**Depositary receipts —** Depositary receipts are securities that evidence ownership interests in, and represent the right to receive, a security or a pool of securities that have been deposited with a bank or trust depository. Certain funds may invest in American Depositary Receipts ("ADRs"), European Depositary Receipts ("EDRs"), Global Depositary Receipts ("GDRs"), and other similar securities. For ADRs, the depository is typically a U.S. financial institution and the underlying securities are issued by a non-U.S. entity. For other depositary receipts, the depository may be a non-U.S. or a U.S. entity, and the underlying securities may be issued by a non-U.S. or a U.S. entity. Depositary receipts will not necessarily be denominated in the same currency as their underlying securities. Generally, ADRs are issued in registered form, denominated in U.S. dollars, and designed for use in the U.S. securities markets. Other depositary receipts, such as EDRs and GDRs, may be issued in bearer form, may be denominated in either U.S. dollars or in non-U.S. currencies, and are primarily designed for use in securities markets outside the United States. ADRs, EDRs and GDRs can be sponsored by the issuing bank or trust company or the issuer of the underlying securities. Although the issuing bank or trust company may impose charges for the collection of dividends and the conversion of such securities into the underlying securities, generally no fees are imposed on the purchase or sale of these securities other than transaction fees ordinarily involved with trading stock. Such securities may be less liquid or may trade at a lower price than the underlying securities of the issuer. Additionally, the issuers of securities underlying depositary receipts may not be obligated to timely disclose information that is considered material under the securities laws of the United States. Therefore, less information may be available regarding these issuers than about the issuers of other securities and there may not be a correlation between such information and the market value of the depositary receipts.

**Inflation-linked bonds —** Certain funds may invest in inflation-linked bonds issued by governments, their agencies or instrumentalities and corporations.

The principal amount of an inflation-linked bond is adjusted in response to changes in the level of an inflation index, such as the Consumer Price Index for Urban Consumers ("CPURNSA"). If the index measuring inflation falls, the principal value or coupon of these securities will be adjusted downward. Consequently, the interest payable on these securities will be reduced. Also, if the principal value of these securities is adjusted according to the rate of inflation, the adjusted principal value repaid at maturity may be less than the original principal. In the case of U.S. Treasury Inflation-Protected Securities ("TIPS"), currently the only inflation-linked security that is issued by the U.S. Treasury, the principal amounts are adjusted daily based upon changes in the rate of inflation (as currently represented by the non-seasonally adjusted CPURNSA, calculated with a three-month lag). TIPS may pay interest semi-annually, equal to a fixed percentage of the inflation-adjusted principal amount. The interest rate on these bonds is fixed at issuance, but over the life of the bond this interest may be paid on an increasing or decreasing principal amount that has been adjusted for inflation. The current market value of TIPS is not guaranteed and will fluctuate. However, the U.S. government guarantees that, at maturity, principal will be repaid at the higher of the original face value of the security (in the event of deflation) or the inflation adjusted value.

American Funds Insurance Series — Page 21

------

Other non-U.S. sovereign governments also issue inflation-linked securities that are tied to their own local consumer price indexes and that offer similar deflationary protection. In certain of these non-U.S. jurisdictions, the repayment of the original bond principal upon the maturity of an inflation-linked bond is not guaranteed, allowing for the amount of the bond repaid at maturity to be less than par. Corporations also periodically issue inflation-linked securities tied to CPURNSA or similar inflationary indexes. While TIPS and non-U.S. sovereign inflation-linked securities are currently the largest part of the inflation-linked market, the fund may invest in corporate inflation-linked securities.

The value of inflation-linked securities is expected to change in response to the changes in real interest rates. Real interest rates, in turn, are tied to the relationship between nominal interest rates and the rate of inflation. If inflation were to rise at a faster rate than nominal interest rates, real interest rates would decline, leading to an increase in value of the inflation-linked securities. In contrast, if nominal interest rates were to increase at a faster rate than inflation, real interest rates might rise, leading to a decrease in value of inflation-linked securities. There can be no assurance, however, that the value of inflation-linked securities will be directly correlated to the changes in interest rates. If interest rates rise due to reasons other than inflation, investors in these securities may not be protected to the extent that the increase is not reflected in the security's inflation measure.

The interest rate for inflation-linked bonds is fixed at issuance as a percentage of this adjustable principal. Accordingly, the actual interest income may both rise and fall as the principal amount of the bonds adjusts in response to movements of the consumer price index. For example, typically interest income would rise during a period of inflation and fall during a period of deflation.

The market for inflation-linked securities may be less developed or liquid, and more volatile, than certain other securities markets. There is a limited number of inflation-linked securities currently available for the fund to purchase, making the market less liquid and more volatile than the U.S. Treasury and agency markets.

**Municipal bonds —** Municipal bonds are debt obligations that are exempt from federal, state and/or local income taxes. Opinions relating to the validity of municipal bonds, exclusion of municipal bond interest from an investor's gross income for federal income tax purposes and, where applicable, state and local income tax, are rendered by bond counsel to the issuing authorities at the time of issuance.

The two principal classifications of municipal bonds are general obligation bonds and limited obligation or revenue bonds. General obligation bonds are secured by the issuer's pledge of its full faith and credit including, if available, its taxing power for the payment of principal and interest. Issuers of general obligation bonds include states, counties, cities, towns and various regional or special districts. The proceeds of these obligations are used to fund a wide range of public facilities, such as the construction or improvement of schools, highways and roads, water and sewer systems and facilities for a variety of other public purposes. Lease revenue bonds or certificates of participation in leases are payable from annual lease rental payments from a state or locality. Annual rental payments are payable to the extent such rental payments are appropriated annually.

Typically, the only security for a limited obligation or revenue bond is the net revenue derived from a particular facility or class of facilities financed thereby or, in some cases, from the proceeds of a special tax or other special revenues. Revenue bonds have been issued to fund a wide variety of revenue-producing public capital projects including: electric, gas, water and sewer systems; highways, bridges and tunnels; port and airport facilities; colleges and universities; hospitals; and convention, recreational, tribal gaming and housing facilities. Although the security behind these bonds varies widely, many provide additional security in the form of a debt service reserve fund which may also be used to make principal and interest payments on the issuer's obligations. In addition, some revenue obligations (as well as general obligations) are insured by a bond insurance company or backed by a letter of credit issued by a banking institution.

American Funds Insurance Series — Page 22

------

Revenue bonds also include, for example, pollution control, health care and housing bonds, which, although nominally issued by municipal authorities, are generally not secured by the taxing power of the municipality but by the revenues of the authority derived from payments by the private entity which owns or operates the facility financed with the proceeds of the bonds. Obligations of housing finance authorities have a wide range of security features, including reserve funds and insured or subsidized mortgages, as well as the net revenues from housing or other public projects. Many of these bonds do not generally constitute the pledge of the credit of the issuer of such bonds. The credit quality of such revenue bonds is usually directly related to the credit standing of the user of the facility being financed or of an institution which provides a guarantee, letter of credit or other credit enhancement for the bond issue.

**Insured municipal bonds —** The fund may invest in municipal bonds that are insured generally as to the timely payment of interest and repayment of principal. The insurance for such bonds may be purchased by the bond issuer, the fund or any other party, and is usually purchased from private, non-governmental insurance companies. Insurance that covers a municipal bond is expected to protect the fund against losses caused by a bond issuer's failure to make interest or principal payments. However, insurance does not guarantee the market value of the bond or the prices of the fund's shares. Also, the investment adviser cannot be certain that the insurance company will make payments it guarantees. The market value of the bond could drop if a bond's insurer fails to fulfill its obligations. Market conditions or changes to ratings criteria could adversely impact the ratings of municipal bond insurers. When rating agencies lower or withdraw the credit rating of the insurer, the insurance may be providing little or no enhancement of credit or resale value to the municipal bond.

**Real estate investment trusts —** Real estate investment trusts ("REITs"), which primarily invest in real estate or real estate-related loans, may issue equity or debt securities. Equity REITs own real estate properties, while mortgage REITs hold construction, development and/or long-term mortgage loans. The values of REITs may be affected by changes in the value of the underlying property of the trusts, the creditworthiness of the issuer, property taxes, interest rates, tax laws and regulatory requirements, such as those relating to the environment. Both types of REITs are dependent upon management skill and the cash flows generated by their holdings, the real estate market in general and the possibility of failing to qualify for any applicable pass-through tax treatment or failing to maintain any applicable exemptive status afforded under relevant laws.

**Variable and floating rate obligations —** The interest rates payable on certain securities and other instruments in which certain of the funds may invest may not be fixed but may fluctuate based upon changes in market interest rates or credit ratings. Variable and floating rate obligations bear coupon rates that are adjusted at designated intervals, based on the then current market interest rates or credit ratings. The rate adjustment features tend to limit the extent to which the market value of the obligations will fluctuate. When the fund holds variable or floating rate securities, a decrease in market interest rates will adversely affect the income received from such securities and the net asset value of the fund's shares.

**Cash and cash equivalents —** The fund may hold cash or invest in cash equivalents. Cash equivalents include, but are not limited to: (*a*) shares of money market or similar funds managed by the investment adviser or its affiliates; (*b*) shares of other money market funds; (*c*) commercial paper; (*d*) short-term bank obligations (for example, certificates of deposit, bankers' acceptances (time drafts on a commercial bank where the bank accepts an irrevocable obligation to pay at maturity)) or bank notes; (*e*) savings association and savings bank obligations (for example, bank notes and certificates of deposit issued by savings banks or savings associations); (*f*) securities of the U.S. government, its agencies or instrumentalities that mature, or that may be redeemed, in one year or less; and (*g*) higher quality corporate bonds and notes that mature, or that may be redeemed, in one year or less.

**Commercial paper —** The fund may purchase commercial paper. Commercial paper refers to short-term promissory notes issued by a corporation to finance its current operations. Such securities

American Funds Insurance Series — Page 23

normally have maturities of thirteen months or less and, though commercial paper is often unsecured, commercial paper may be supported by letters of credit, surety bonds or other forms of collateral. Maturing commercial paper issuances are usually repaid by the issuer from the proceeds of new commercial paper issuances. As a result, investment in commercial paper is subject to rollover risk, or the risk that the issuer cannot issue enough new commercial paper to satisfy its outstanding commercial paper. Like all fixed income securities, commercial paper prices are susceptible to fluctuations in interest rates. If interest rates rise, commercial paper prices will decline and vice versa. However, the short-term nature of a commercial paper investment makes it less susceptible to volatility than many other fixed income securities because interest rate risk typically increases as maturity lengths increase. Commercial paper tends to yield smaller returns than longer-term corporate debt because securities with shorter maturities typically have lower effective yields than those with longer maturities. As with all fixed income securities, there is a chance that the issuer will default on its commercial paper obligations and commercial paper may become illiquid or suffer from reduced liquidity in these or other situations.

Commercial paper in which the fund may invest includes commercial paper issued in reliance on the exemption from registration afforded by Section 4(a)(2) of the Securities Act of 1933, as amended (the "1933 Act"). Section 4(a)(2) commercial paper has substantially the same price and liquidity characteristics as commercial paper generally, except that the resale of Section 4(a)(2) commercial paper is limited to institutional investors who agree that they are purchasing the paper for investment purposes and not with a view to public distribution. Technically, such a restriction on resale renders Section 4(a)(2) commercial paper a restricted security under the 1933 Act. In practice, however, Section 4(a)(2) commercial paper typically can be resold as easily as any other unrestricted security held by the fund. Accordingly, Section 4(a)(2) commercial paper has been generally determined to be liquid under procedures adopted by the fund's board of trustees.

**Restricted or illiquid securities —** Certain funds may purchase securities subject to restrictions on resale. Restricted securities may only be sold pursuant to an exemption from registration under the Securities Act of 1933, as amended (the "1933 Act"), or in a registered public offering. Restricted securities held by the fund are often eligible for resale under Rule 144A, an exemption under the 1933 Act allowing for resales to "Qualified Institutional Buyers." Where registration is required, the holder of a registered security may be obligated to pay all or part of the registration expense and a considerable period may elapse between the time it decides to seek registration and the time it may be permitted to sell a security under an effective registration statement. Difficulty in selling such securities may result in a loss to the fund or cause it to incur additional administrative costs.

Some fund holdings (including some restricted securities) may be deemed illiquid if the fund expects that a reasonable portion of the holding cannot be sold in seven calendar days or less without the sale significantly changing the market value of the investment. The determination of whether a holding is considered illiquid is made by the Series' adviser under a liquidity risk management program adopted by the Series' board and administered by the Series' adviser. The fund may incur significant additional costs in disposing of illiquid securities.

**Loan assignments and participations —** Certain funds may invest in loans or other forms of indebtedness that represent interests in amounts owed by corporations or other borrowers (collectively "borrowers"). Loans may be originated by the borrower in order to address its working capital needs, as a result of a reorganization of the borrower's assets and liabilities (recapitalizations), to merge with or acquire another company (mergers and acquisitions), to take control of another company (leveraged buy-outs), to provide temporary financing (bridge loans), or for other corporate purposes.

Some loans may be secured in whole or in part by assets or other collateral. The greater the value of the assets securing the loan the more the lender is protected against loss in the case of nonpayment of

American Funds Insurance Series — Page 24

------

principal or interest. Loans made to highly leveraged borrowers may be especially vulnerable to adverse changes in economic or market conditions and may involve a greater risk of default.

Some loans may represent revolving credit facilities or delayed funding loans, in which a lender agrees to make loans up to a maximum amount upon demand by the borrower during a specified term. These commitments may have the effect of requiring the fund to increase its investment in a company at a time when it might not otherwise decide to do so (including at a time when the company's financial condition makes it unlikely that such amounts will be repaid).

Some loans may represent debtor-in-possession financings (commonly known as "DIP financings"). DIP financings are arranged when an entity seeks the protections of the bankruptcy court under Chapter 11 of the U.S. Bankruptcy Code. These financings allow the entity to continue its business operations while reorganizing under Chapter 11. Such financings constitute senior liens on unencumbered collateral (i.e., collateral not subject to other creditors' claims). There is a risk that the entity will not emerge from Chapter 11 and will be forced to liquidate its assets under Chapter 7 of the U.S. Bankruptcy Code. In the event of liquidation, the fund's only recourse will be against the collateral securing the DIP financing.

The investment adviser generally makes investment decisions based on publicly available information, but may rely on non-public information if necessary. Borrowers may offer to provide lenders with material, non-public information regarding a specific loan or the borrower in general. The investment adviser generally chooses not to receive this information. As a result, the investment adviser may be at a disadvantage compared to other investors that may receive such information. The investment adviser's decision not to receive material, non-public information may impact the investment adviser's ability to assess a borrower's requests for amendments or waivers of provisions in the loan agreement. However, the investment adviser may on a case-by-case basis decide to receive such information when it deems prudent. In these situations the investment adviser may be restricted from trading the loan or buying or selling other debt and equity securities of the borrower while it is in possession of such material, non-public information, even if such loan or other security is declining in value.

The fund normally acquires loan obligations through an assignment from another lender, but also may acquire loan obligations by purchasing participation interests from lenders or other holders of the interests. When the fund purchases assignments, it acquires direct contractual rights against the borrower on the loan. The fund acquires the right to receive principal and interest payments directly from the borrower and to enforce their rights as a lender directly against the borrower. However, because assignments are arranged through private negotiations between potential assignees and potential assignors, the rights and obligations acquired by the fund as the purchaser of an assignment may differ from, and be more limited than, those held by the assigning lender. Loan assignments are often administered by a financial institution that acts as agent for the holders of the loan, and the fund may be required to receive approval from the agent and/or borrower prior to the purchase of a loan. Risks may also arise due to the inability of the agent to meet its obligations under the loan agreement.

Loan participations are loans or other direct debt instruments that are interests in amounts owed by the borrower to another party. They may represent amounts owed to lenders or lending syndicates, to suppliers of goods or services, or to other parties. The fund will have the right to receive payments of principal, interest and any fees to which it is entitled only from the lender selling the participation and only upon receipt by the lender of the payments from the borrower. In connection with purchasing participations, the fund generally will have no right to enforce compliance by the borrower with the terms of the loan agreement relating to the loan, nor any rights of set-off against the borrower. In addition, the fund may not directly benefit from any collateral supporting the loan in which it has purchased the participation and the fund will have to rely on the agent bank or other financial intermediary to apply appropriate credit remedies. As a result, the fund will be subject to the credit risk of both the borrower and the lender that is selling the participation. In the event of the insolvency of

American Funds Insurance Series — Page 25

------

the lender selling a participation, the fund may be treated as a general creditor of the lender and may not benefit from any set-off between the lender and the borrower.

Loan assignments and participations are generally subject to legal or contractual restrictions on resale and are not currently listed on any securities exchange or automatic quotation system. Risks may arise due to delayed settlements of loan assignments and participations. The investment adviser expects that most loan assignments and participations purchased for the fund will trade on a secondary market. However, although secondary markets for investments in loans are growing among institutional investors, a limited number of investors may be interested in a specific loan. It is possible that loan participations, in particular, could be sold only to a limited number of institutional investors. If there is no active secondary market for a particular loan, it may be difficult for the investment adviser to sell the fund's interest in such loan at a price that is acceptable to it and to obtain pricing information on such loan.

Investments in loan participations and assignments present the possibility that the fund could be held liable as a co-lender under emerging legal theories of lender liability. In addition, if the loan is foreclosed, the fund could be part owner of any collateral and could bear the costs and liabilities of owning and disposing of the collateral. The fund anticipates that loan participations could be sold only to a limited number of institutional investors. In addition, some loan participations and assignments may not be rated by major rating agencies and may not be protected by securities laws.

**Unfunded commitment agreements —** The fund may enter into unfunded commitment agreements to make certain investments, including unsettled bank loan purchase transactions. Under the SEC's rule applicable to the fund's use of derivatives, unfunded commitment agreements are not derivatives transactions. The fund will only enter into such unfunded commitment agreements if the fund reasonably believes, at the time it enters into such agreement, that it will have sufficient cash and cash equivalents to meet its obligations with respect to all of its unfunded commitment agreements as they come due.

**Inverse floating rate notes —** Certain funds may invest in inverse floating rate notes (a type of derivative instrument). These notes have rates that move in the opposite direction of prevailing interest rates. A change in prevailing interest rates will often result in a greater change in these instruments' interest rates. As a result, these instruments may have a greater degree of volatility than other types of interest-bearing securities.

**Reinsurance related notes and bonds —** American High-Income Trust may invest in reinsurance related notes and bonds. These instruments, which are typically issued by special purpose reinsurance companies, transfer an element of insurance risk to the note or bond holders. For example, such a note or bond could provide that the reinsurance company would not be required to repay all or a portion of the principal value of the note or bond if losses due to a catastrophic event under the policy (such as a major hurricane) exceed certain dollar thresholds. Consequently, the fund may lose the entire amount of its investment in such bonds or notes if such an event occurs and losses exceed certain dollar thresholds. In this instance, investors would have no recourse against the insurance company. These instruments may be issued with fixed or variable interest rates and rated in a variety of credit quality categories by the rating agencies.

**Repurchase agreements —** Certain funds may enter into repurchase agreements, or "repos", under which the fund buys a security and obtains a simultaneous commitment from the seller to repurchase the security at a specified time and price. Because the security purchased constitutes collateral for the repurchase obligation, a repo may be considered a loan by the fund that is collateralized by the security purchased. Repos permit the fund to maintain liquidity and earn income over periods of time as short as overnight.

American Funds Insurance Series — Page 26

------

The seller must maintain with a custodian collateral equal to at least the repurchase price, including accrued interest. In tri-party repos and centrally cleared or "sponsored" repos, a third-party custodian, either a clearing bank in the case of tri-party repos or a central clearing counterparty in the case of centrally cleared repos, facilitates repo clearing and settlement, including by providing collateral management services. In bilateral repos, the parties themselves are responsible for settling transactions.

The fund will only enter into repos involving securities of the type (excluding any maturity limitations) in which they could otherwise invest. If the seller under the repo defaults, the fund may incur a loss if the value of the collateral securing the repo has declined and may incur disposition costs and delays in connection with liquidating the collateral. If bankruptcy proceedings are commenced with respect to the seller, realization of the collateral by the fund may be delayed or limited.

**Maturity —** There are no restrictions on the maturity compositions of the portfolios of certain funds. Certain funds invest in debt securities with a wide range of maturities. Under normal market conditions, longer term securities yield more than shorter term securities, but are subject to greater price fluctuations.

**Adjustment of maturities —** The investment adviser seeks to anticipate movements in interest rates and may adjust the maturity distribution of the portfolio accordingly, keeping in mind the fund's objective(s).

**Derivatives —** In pursuing its investment objective(s), the fund may invest in derivative instruments. A derivative is a financial instrument, the value of which depends on, or is otherwise derived from, another underlying variable. Most often, the variable underlying a derivative is the price of a traded asset, such as a traditional cash security (e.g., a stock or bond), a currency or a commodity; however, the value of a derivative can be dependent on almost any variable, from the level of an index or a specified rate to the occurrence (or non-occurrence) of a credit event with respect to a specified reference asset. In addition to investing in forward currency contracts and currency options, as described under "Currency transactions," the fund may take positions in futures contracts and options on futures contracts and swaps, each of which is a derivative instrument described in greater detail below.

Derivative instruments may be distinguished by the manner in which they trade: some are standardized instruments that trade on an organized exchange while others are individually negotiated and traded in the over-the-counter ("OTC") market. Derivatives also range broadly in complexity, from simple derivatives to more complex instruments. As a general matter, however, all derivatives — regardless of the manner in which they trade or their relative complexities — entail certain risks, some of which are different from, and potentially greater than, the risks associated with investing directly in traditional cash securities.

As is the case with traditional cash securities, derivative instruments are generally subject to counterparty credit risk; however, in some cases, derivatives may pose counterparty risks greater than those posed by cash securities. The use of derivatives involves the risk that a loss may be sustained by the fund as a result of the failure of the fund's counterparty to make required payments or otherwise to comply with its contractual obligations. For some derivatives, though, the value of — and, in effect, the return on — the instrument may be dependent on both the individual credit of the fund's counterparty and on the credit of one or more issuers of any underlying assets. If the fund does not correctly evaluate the creditworthiness of its counterparty and, where applicable, of issuers of any underlying reference assets, the fund's investment in a derivative instrument may result in losses. Further, if a fund's counterparty were to default on its obligations, the fund's contractual remedies against such counterparty may be subject to applicable bankruptcy and insolvency laws, which could affect the fund's rights as a creditor and delay or impede the fund's ability to receive the net amount of payments

------

that it is contractually entitled to receive. Derivative instruments are subject to additional risks, including operational risk (such as documentation issues, settlement issues and systems failures) and legal risk (such as insufficient documentation, insufficient capacity or authority of a counterparty, and issues with the legality or enforceability of a contract).

The value of some derivative instruments in which the fund invests may be particularly sensitive to changes in prevailing interest rates, currency exchange rates or other market conditions. Like the fund's other investments, the ability of the fund to successfully utilize such derivative instruments may depend in part upon the ability of the fund's investment adviser to accurately forecast interest rates and other economic factors. The success of the fund's derivative investment strategy will also depend on the investment adviser's ability to assess and predict the impact of market or economic developments on the derivative instruments in which the fund invests, in some cases without having had the benefit of observing the performance of a derivative under all possible market conditions. If the investment adviser incorrectly forecasts such factors and has taken positions in derivative instruments contrary to prevailing market trends, or if the investment adviser incorrectly predicts the impact of developments on a derivative instrument, the fund could suffer losses.

Certain derivatives may also be subject to liquidity and valuation risks. The potential lack of a liquid secondary market for a derivative (and, particularly, for an OTC derivative, including swaps and OTC options) may cause difficulty in valuing or selling the instrument. If a derivative transaction is particularly large or if the relevant market is illiquid, as is often the case with many privately-negotiated OTC derivatives, the fund may not be able to initiate a transaction or to liquidate a position at an advantageous time or price. Particularly when there is no liquid secondary market for the fund's derivative positions, the fund may encounter difficulty in valuing such illiquid positions. The value of a derivative instrument does not always correlate perfectly with its underlying asset, rate or index, and many derivatives, and OTC derivatives in particular, are complex and often valued subjectively. Improper valuations can result in increased cash payment requirements to counterparties or a loss of value to the fund.

Because certain derivative instruments may obligate the fund to make one or more potential future payments, which could significantly exceed the value of the fund's initial investments in such instruments, derivative instruments may also have a leveraging effect on the fund's portfolio. Certain derivatives have the potential for unlimited loss, irrespective of the size of the fund's investment in the instrument. When a fund leverages its portfolio, investments in that fund will tend to be more volatile, resulting in larger gains or losses in response to market changes.

The fund's compliance with the SEC's rule applicable to the fund's use of derivatives may limit the ability of the fund to use derivatives as part of its investment strategy. The rule requires that a fund that uses derivatives in more than a limited manner, which is currently the case for the fund, adopt a derivatives risk management program, appoint a derivatives risk manager and comply with an outer limit on leverage based on value at risk, or "VaR". VaR is an estimate of an instrument's or portfolio's potential losses over a given time horizon (i.e., 20 trading days) and at a specified confidence level (i.e., 99%). VaR will not provide, and is not intended to provide, an estimate of an instrument's or portfolio's maximum potential loss amount. For example, a VaR of 5% with a specified confidence level of 99% would mean that a VaR model estimates that 99% of the time a fund would not be expected to lose more than 5% of its total assets over the given time period. However, 1% of the time, the fund would be expected to lose more than 5% of its total assets, and in such a scenario the VaR model does not provide an estimate of the extent of this potential loss. The derivatives rule may not be effective in limiting the fund's risk of loss, as measurements of VaR rely on historical data and may not accurately measure the degree of risk reflected in the fund's derivatives or other investments. A fund is generally required to satisfy the rule's outer limit on leverage by limiting the fund's VaR to 200% of the VaR of a designated reference portfolio that does not utilize derivatives each business day. If a fund does not have an appropriate designated reference portfolio in light of the fund's investments, investment

objectives and strategy, a fund must satisfy the rule's outer limit on leverage by limiting the fund's VaR to 20% of the value of the fund's net assets each business day.

**Options** — The fund may invest in option contracts, including options on futures and options on currencies, as described in more detail under "Futures and Options on Futures" and "Currency Transactions," respectively. An option contract is a contract that gives the holder of the option, in return for a premium payment, the right to buy from (in the case of a call) or sell to (in the case of a put) the writer of the option the reference instrument underlying the option (or the cash value of the instrument underlying the option) at a specified exercise price. The writer of an option on a security has the obligation, upon exercise of the option, to cash settle or deliver the underlying currency or instrument upon payment of the exercise price (in the case of a call) or to cash settle or take delivery of the underlying currency or instrument and pay the exercise price (in the case of a put).

By purchasing a put option, the fund obtains the right (but not the obligation) to sell the currency or instrument underlying the option (or to deliver the cash value of the instrument underlying the option) at a specified exercise price, which is also referred to as the strike price. In return for this right, the fund pays the current market price, or the option premium, for the option. The fund may terminate its position in a put option by allowing the option to expire or by exercising the option. If the option is allowed to expire, the fund will lose the entire amount of the option premium paid. If the option is exercised, the fund completes the sale of the underlying instrument (or cash settles) at the strike price. The fund may also terminate a put option position by entering into opposing close-out transactions in advance of the option expiration date.

As a buyer of a put option, the fund can expect to realize a gain if the price of the underlying currency or instrument falls substantially. However, if the price of the underlying currency or instrument does not fall enough to offset the cost of purchasing the option, the fund can expect to suffer a loss, albeit a loss limited to the amount of the option premium plus any applicable transaction costs.

The features of call options are essentially the same as those of put options, except that the purchaser of a call option obtains the right (but not the obligation) to purchase, rather than sell, the underlying currency or instrument (or cash settle) at the specified strike price. The buyer of a call option typically attempts to participate in potential price increases of the underlying currency or instrument with risk limited to the cost of the option if the price of the underlying currency or instrument falls. At the same time, the call option buyer can expect to suffer a loss if the price of the underlying currency or instrument does not rise sufficiently to offset the cost of the option.

The writer of a put or call option takes the opposite side of the transaction from the option purchaser. In return for receipt of the option premium, the writer assumes the obligation to pay or receive the strike price for the option's underlying currency or instrument if the other party to the option chooses to exercise it. The writer may seek to terminate a position in a put option before exercise by entering into opposing close-out transactions in advance of the option expiration date. If the market for the relevant put option is not liquid, however, the writer must be prepared to pay the strike price while the option is outstanding, regardless of price changes.

If the price of the underlying currency or instrument rises, a put writer would generally expect to profit, although its gain would be limited to the amount of the premium it received. If the price of the underlying currency or instrument remains the same over time, it is likely that the writer would also profit because it should be able to close out the option at a lower price. This

American Funds Insurance Series — Page 29

------

is because an option's value decreases with time as the currency or instrument approaches its expiration date. If the price of the underlying currency or instrument falls, the put writer would expect to suffer a loss. This loss should be less than the loss from purchasing the underlying currency or instrument directly, however, because the premium received for writing the option should mitigate the effects of the decline.

Writing a call option obligates the writer to, upon exercise of the option, deliver the option's underlying currency or instrument in return for the strike price or to make a net cash settlement payment, as applicable. The characteristics of writing call options are similar to those of writing put options, except that writing call options is generally a profitable strategy if prices remain the same or fall. The potential gain for the option seller in such a transaction would be capped at the premium received.

Several risks are associated with transactions in options on currencies, securities and other instruments (referred to as the "underlying instruments"). For example, there may be significant differences between the underlying instruments and options markets that could result in an imperfect correlation between these markets, which could cause a given transaction not to achieve its objectives. When a put or call option on a particular underlying instrument is purchased to hedge against price movements in a related underlying instrument, for example, the price to close out the put or call option may move more or less than the price of the related underlying instrument.

Options prices can diverge from the prices of their underlying instruments for a number of reasons. Options prices are affected by such factors as current and anticipated short-term interest rates, changes in the volatility of the underlying instrument, and the time remaining until expiration of the contract, which may not affect security prices in the same way. Imperfect correlation may also result from differing levels of demand in the options markets and the markets for the underlying instruments, from structural differences in how options and underlying instruments are traded, or from imposition of daily price fluctuation limits or trading halts. The fund may purchase or sell options contracts with a greater or lesser value than the underlying instruments it wishes to hedge or intends to purchase in order to attempt to compensate for differences in volatility between the contract and the underlying instruments, although this may not be successful. If price changes in the fund's options positions are less correlated with its other investments, the positions may fail to produce anticipated gains or result in losses that are not offset by gains in other investments.

There is no assurance that a liquid market will exist for any particular options contract at any particular time. Options may have relatively low trading volumes and liquidity if their strike prices are not close to the current prices of the underlying instruments. In addition, exchanges may establish daily price fluctuation limits for exchange-traded options contracts and may halt trading if a contract's price moves upward or downward more than the limit in a given day. On volatile trading days when the price fluctuation limit is reached or a trading halt is imposed, it may be impossible to enter into new positions or to close out existing positions. If the market for a contract is not liquid because of price fluctuation limits or otherwise, it could prevent prompt liquidation of unfavorable positions and could potentially require the fund to hold a position until delivery or expiration regardless of changes in its value.

Combined positions involve purchasing and writing options in combination with each other, or in combination with futures or forward contracts, in order to adjust the risk and return profile of the fund's overall position. For example, purchasing a put option and writing a call option on the same underlying instrument could construct a combined position with risk and return characteristics similar to selling a futures contract (but with leverage embedded). Another possible combined position would involve writing a call option at one strike price and buying a call option at a lower strike price to reduce the risk of the written call option in the event of a

American Funds Insurance Series — Page 30

------

substantial price increase. Because such combined options positions involve multiple trades, they result in higher transaction costs and may be more difficult to open and close out.

**Futures and options on futures** — The fund may enter into futures contracts and options on futures contracts to seek to manage the fund's interest rate sensitivity by increasing or decreasing the duration of the fund or a portion of the fund's portfolio. A futures contract is an agreement to buy or sell a security or other financial instrument (the "reference asset") for a set price on a future date. An option on a futures contract gives the holder of the option the right to buy or sell a position in a futures contract from or to the writer of the option, at a specified price on or before the specified expiration date. Futures contracts and options on futures contracts are standardized, exchange-traded contracts, and, when such contracts are bought or sold, the fund will incur brokerage fees and will be required to maintain margin deposits.

Unlike when the fund purchases or sells a security, such as a stock or bond, no price is paid or received by the fund upon the purchase or sale of a futures contract. When the fund enters into a futures contract, the fund is required to deposit with its futures broker, known as a futures commission merchant ("FCM"), a specified amount of liquid assets in a segregated account in the name of the FCM at the applicable derivatives clearinghouse or exchange. This amount, known as initial margin, is set by the futures exchange on which the contract is traded and may be significantly modified during the term of the contract. The initial margin is in the nature of a performance bond or good faith deposit on the futures contract, which is returned to the fund upon termination of the contract, assuming all contractual obligations have been satisfied. Additionally, on a daily basis, the fund pays or receives cash, or variation margin, equal to the daily change in value of the futures contract. Variation margin does not represent a borrowing or loan by the fund but is instead a settlement between the fund and the FCM of the amount one party would owe the other if the futures contract expired. In computing daily net asset value, the fund will mark-to-market its open futures positions. A fund is also required to deposit and maintain margin with an FCM with respect to put and call options on futures contracts written by the fund. Such margin deposits will vary depending on the nature of the underlying futures contract (and related initial margin requirements), the current market value of the option, and other futures positions held by the fund. In the event of the bankruptcy or insolvency of an FCM that holds margin on behalf of the fund, the fund may be entitled to return of margin owed to it only in proportion to the amount received by the FCM's other customers, potentially resulting in losses to the fund. An event of bankruptcy or insolvency at a clearinghouse or exchange holding initial margin could also result in losses for the fund.

When the fund invests in futures contracts and options on futures contracts and deposits margin with an FCM, the fund becomes subject to so-called "fellow customer" risk – that is, the risk that one or more customers of the FCM will default on their obligations and that the resulting losses will be so great that the FCM will default on its obligations and margin posted by one customer, such as the fund, will be used to cover a loss caused by a different defaulting customer. Applicable Commodity Futures Trading Commission ("CFTC") rules generally prohibit the use of one customer's funds to meet the obligations of another customer and limit the ability of an FCM to use margin posed by non-defaulting customers to satisfy losses caused by defaulting customers. As a general matter, an FCM is required to use its own funds to meet a defaulting customer's obligations. While a customer's loss would likely need to be substantial before non-defaulting customers would be exposed to loss on account of fellow customer risk, applicable CFTC rules nevertheless permit the commingling of margin and do not limit the mutualization of customer losses from investment losses, custodial failures, fraud or other causes. If the loss is so great that, notwithstanding the application of an FCM's own funds, there is a shortfall in the amount of customer funds required to be held in segregation, the FCM could default and be placed into bankruptcy. Under these circumstances, bankruptcy law provides that non-defaulting customers will share pro rata in any shortfall. A shortfall in

American Funds Insurance Series — Page 31

customer segregated funds may also make the transfer of the accounts of non-defaulting customers to another FCM more difficult.

Although certain futures contracts, by their terms, require actual future delivery of and payment for the reference asset, in practice, most futures contracts are usually closed out before the delivery date by offsetting purchases or sales of matching futures contracts. Closing out an open futures contract purchase or sale is effected by entering into an offsetting futures contract sale or purchase, respectively, for the same aggregate amount of the identical reference asset and the same delivery date. If the offsetting purchase price is less than the original sale price (in each case taking into account transaction costs, including brokerage fees), the fund realizes a gain; if it is more, the fund realizes a loss. Conversely, if the offsetting sale price is more than the original purchase price (in each case taking into account transaction costs, including brokerage fees), the fund realizes a gain; if it is less, the fund realizes a loss.

The fund may purchase and write call and put options on futures. A futures option gives the holder the right, in return for the premium paid, to assume a long position (call) or short position (put) in a futures contract at a specified exercise price at any time during the period of the option. Upon exercise of a call option, the holder acquires a long position in the futures contract, and the writer is assigned the opposite short position. The opposite is true in the case of a put option. A call option is "in the money" if the value of the futures contract that is the subject of the option exceeds the exercise price. A put option is "in the money" if the exercise price exceeds the value of the futures contract that is the subject of the option. See also "Options" above for a general description of investment techniques and risks relating to options.

The value of a futures contract tends to increase and decrease in tandem with the value of its underlying reference asset. Purchasing futures contracts will, therefore, tend to increase the fund's exposure to positive and negative price fluctuations in the reference asset, much as if the fund had purchased the reference asset directly. When the fund sells a futures contract, by contrast, the value of its futures position will tend to move in a direction contrary to the market for the reference asset. Accordingly, selling futures contracts will tend to offset both positive and negative market price changes, much as if the reference asset had been sold.

There is no assurance that a liquid market will exist for any particular futures or futures options contract at any particular time. Futures exchanges may establish daily price fluctuation limits for futures contracts and may halt trading if a contract's price moves upward or downward more than the limit in a given day. On volatile trading days, when the price fluctuation limit is reached and a trading halt is imposed, it may be impossible to enter into new positions or close out existing positions. If the market for a futures contract is not liquid because of price fluctuation limits or other market conditions, the fund may be prevented from promptly liquidating unfavorable futures positions and the fund could be required to continue to hold a position until delivery or expiration regardless of changes in its value, potentially subjecting the fund to substantial losses. Additionally, the fund may not be able to take other actions or enter into other transactions to limit or reduce its exposure to the position. Under such circumstances, the fund would remain obligated to meet margin requirements until the position is cleared. As a result, the fund's access to other assets posted as margin for its futures positions could also be impaired.

Although futures exchanges generally operate similarly in the United States and abroad, foreign futures exchanges may follow trading, settlement and margin procedures that are different than those followed by futures exchanges in the United States. Futures and futures options contracts traded outside the United States may not involve a clearing mechanism or related guarantees and may involve greater risk of loss than U.S.-traded contracts, including potentially greater risk of losses due to insolvency of a futures broker, exchange member, or

------

other party that may owe initial or variation margin to the fund. Margin requirements on foreign futures exchanges may be different than those of futures exchanges in the United States, and, because initial and variation margin payments may be measured in foreign currency, a futures or futures options contract traded outside the United States may also involve the risk of foreign currency fluctuations.

**Swaps —** The fund may enter into swaps, which are two-party contracts entered into primarily by institutional investors for a specified time period. In a typical swap, two parties agree to exchange the returns earned or realized from one or more underlying assets or rates of return.

Swaps can be traded on a swap execution facility ("SEF") and cleared through a central clearinghouse (cleared), traded OTC and cleared, or traded bilaterally and not cleared. For example, standardized interest rate swaps and standardized credit default swap indices are traded on SEFs and cleared. Other forms of swaps, such as total return swaps and certain types of interest rate swaps and credit default swap indices are entered into on a bilateral basis. Because clearing interposes a central clearinghouse as the ultimate counterparty to each participant's swap, and margin is required to be exchanged under the rules of the clearinghouse, central clearing is intended to decrease (but not eliminate) counterparty risk relative to uncleared bilateral swaps. To the extent the fund enters into bilaterally negotiated swaps, the fund will enter into swaps only with counterparties that meet certain credit standards and have agreed to specific collateralization procedures; however, if the counterparty's creditworthiness deteriorates rapidly and the counterparty defaults on its obligations under the swap or declares bankruptcy, the fund may lose any amount it expected to receive from the counterparty. In addition, bilateral swaps are subject to certain regulatory margin requirements that mandate the posting and collection of minimum margin amounts, which may result in the fund and its counterparties posting higher margin amounts for bilateral swaps than would otherwise be the case.

The term of a swap can be days, months or years and certain swaps may be less liquid than others. If a swap is particularly large or if the relevant market is illiquid, it may not be possible to initiate a transaction or liquidate a position at an advantageous time or price, which may result in significant losses.

Swaps can take different forms. The fund may enter into the following types of swaps:

**Interest rate swaps —** The fund may enter into interest rate swaps to seek to manage the interest rate sensitivity of the fund by increasing or decreasing the duration of the fund or a portion of the fund's portfolio. An interest rate swap is an agreement between two parties to exchange or swap payments based on changes in an interest rate or rates. Typically, one interest rate is fixed and the other is variable based on a designated short-term interest rate such as the Secured Overnight Financing Rate ("SOFR"), prime rate or other benchmark, or on an inflation index such as the U.S. Consumer Price Index (which is a measure that examines the weighted average of prices of a basket of consumer goods and services and measures changes in the purchasing power of the U.S. dollar and the rate of inflation). In other types of interest rate swaps, known as basis swaps, the parties agree to swap variable interest rates based on different designated short-term interest rates. Interest rate swaps generally do not involve the delivery of securities or other principal amounts. Rather, cash payments are exchanged by the parties based on the application of the designated interest rates to a notional amount, which is the predetermined dollar principal of the trade upon which payment obligations are computed. Accordingly, the fund's current obligation or right under the swap is generally equal to the net amount to be paid or received under the swap based on the relative value of the position held by each party.

------

In addition to the risks of entering into swaps discussed above, the use of interest rate swaps involves the risk of losses if interest rates change.

**Total return swaps —** The fund may enter into total return swaps in order to gain exposure to a market or security without owning or taking physical custody of such security or investing directly in such market. A total return swap is an agreement in which one party agrees to make periodic payments to the other party based on the change in market value of the assets underlying the contract during the specified term in exchange for periodic payments based on a fixed or variable interest rate or the total return from other underlying assets. The asset underlying the contract may be a single security, a basket of securities or a securities index. Like other swaps, the use of total return swaps involves certain risks, including potential losses if a counterparty defaults on its payment obligations to the fund or the underlying assets do not perform as anticipated. There is no guarantee that entering into a total return swap will deliver returns in excess of the interest costs involved and, accordingly, the fund's performance may be lower than would have been achieved by investing directly in the underlying assets.

**Credit default swap indices —** In order to assume exposure to a diversified portfolio of credits or to hedge against existing credit risks, the fund may invest in credit default swap indices, including CDX and iTraxx indices (collectively referred to as "CDSIs"). Additionally, in order to assume exposure to the commercial mortgage-backed security sector or to hedge against existing credit and market risks within such sector, the fund may invest in mortgage-backed security credit default swap indices, including the CMBX index (collectively referred to as "CMBXIs").

A CDSI is based on a portfolio of credit default swaps with similar characteristics, such as credit default swaps on high-yield bonds. A CMBXI is a tradeable index referencing a basket of commercial mortgage-backed securities. In a typical CDSI or CMBXI transaction, one party — the protection buyer — is obligated to pay the other party — the protection seller — a stream of periodic payments over the term of the contract. If a credit event, such as a default or restructuring, occurs with respect to any of the underlying reference obligations, the protection seller must pay the protection buyer the loss on those credits. Also, if a restructuring credit event occurs in an iTraxx index, the fund as protection buyer may receive a single name credit default swap ("CDS") representing the relevant constituent.

The fund may enter into a CDSI or CMBXI transaction as either protection buyer or protection seller. If the fund is a protection buyer, it would pay the counterparty a periodic stream of payments over the term of the contract and would not recover any of those payments if no credit events were to occur with respect to any of the underlying reference obligations. However, if a credit event did occur, the fund, as a protection buyer, would have the right to deliver the referenced debt obligations or a specified amount of cash, depending on the terms of the applicable agreement, and to receive the par value of such debt obligations from the counterparty protection seller. As a protection seller, the fund would receive fixed payments throughout the term of the contract if no credit events were to occur with respect to any of the underlying reference obligations. If a credit event were to occur, however, the value of any deliverable obligation received by the fund, coupled with the periodic payments previously received by the fund, may be less than the full notional value that the fund, as a protection seller, pays to the counterparty protection buyer, effectively resulting in a loss of value to the fund. Furthermore, as a protection seller, the fund would effectively add leverage to its portfolio because it would have investment exposure to the notional amount of the swap.

American Funds Insurance Series — Page 34

------

The use of CDSI or CMBXI, like all other swaps, is subject to certain risks, including the risk that the fund's counterparty will default on its obligations. If such a default were to occur, any contractual remedies that the fund might have may be subject to applicable bankruptcy laws, which could delay or limit the fund's recovery. Thus, if the fund's counterparty to a CDSI or CMBXI transaction defaults on its obligation to make payments thereunder, the fund may lose such payments altogether or collect only a portion thereof, which collection could involve substantial costs or delays.

Additionally, when the fund invests in a CDSI or CMBXI as a protection seller, the fund will be indirectly exposed to the creditworthiness of issuers of the underlying reference obligations in the index. If the investment adviser to the fund does not correctly evaluate the creditworthiness of issuers of the underlying instruments on which the CDSI or CMBXI is based, the investment could result in losses to the fund.

**Equity-linked notes —** A fund may purchase equity-linked notes to enhance the current income of its portfolio. Equity-linked notes are hybrid instruments that are specially designed to combine the characteristics of one or more reference securities — usually a single stock, a stock index or a basket of stocks — and a related equity derivative, such as a put or call option, in a single note form. For example, an equity-linked note that refers to the stock of an issuer may be the economic equivalent of holding a position in that stock and simultaneously selling a call option on that stock with a strike price greater than the current stock price. The holder of the note would be exposed to decreases in the price of the equity to the same extent as if it held the equity directly. However, if the stock appreciated in value, the noteholder would only benefit from stock price increases up to the strike price (i.e., the point at which the holder of the call option would be expected to exercise its right to buy the underlying stock). Additionally, the terms of an equity-linked note may provide for periodic interest payments to holders at either a fixed or floating rate.

As described in the example above, the return on an equity-linked note is generally tied to the performance of the underlying reference security or securities. In addition to any interest payments made during the term of the note, at maturity, the noteholder usually receives a return of principal based on the capital appreciation of the linked securities. Depending on the terms of the issuance, the maximum principal amount to be repaid on the equity-linked note may be capped. For example, in consideration for greater current income or yield, a noteholder may forego its participation in the capital appreciation of the underlying equity assets above a predetermined price limit. Alternatively, if the linked securities have depreciated in value, or if their price fluctuates outside of a preset range, the noteholder may receive only the principal amount of the note, or may lose the principal invested in the equity-linked note entirely.

The price of an equity-linked note is derived from the value of the underlying linked securities. The level and type of risk involved in the purchase of an equity-linked note by the fund is similar to the risk involved in the purchase of the underlying linked securities. However, the value of an equity-linked note is also dependent on the individual credit of the issuer of the note, which, in the case of an unsecured note, will generally be a major financial institution, and, in the case of a collateralized note, will generally be a trust or other special purpose vehicle or finance subsidiary established by a major financial institution for the limited purpose of issuing the note. An investment in an equity-linked note bears the risk that the issuer of the note will default or become bankrupt. In such an event, the fund may have difficulty being repaid, or may fail to be repaid, the principal amount of, or income from, its investment. Like other structured products, equity-linked notes are frequently secured by collateral consisting of a combination of debt or related equity securities to which payments under the notes are linked. If so secured, the fund would look to this underlying collateral for satisfaction of claims in the event that the issuer of an equity-linked note defaulted under the terms of the note. However, depending on the law of the jurisdictions in which an issuer is organized and in which the note is issued, in the event of default, the fund may incur substantial expenses in seeking recovery under an equity-linked note, and may have limited legal recourse in attempting to do so.

American Funds Insurance Series — Page 35

------

Equity-linked notes are often privately placed and may not be rated, in which case the fund will be more dependent than would otherwise be the case on the ability of the investment adviser to evaluate the creditworthiness of the issuer, the underlying security, any collateral features of the note, and the potential for loss due to market and other factors. Ratings of issuers of equity-linked notes refer only to the creditworthiness of the issuer and strength of related collateral arrangements or other credit supports, and do not take into account, or attempt to rate, any potential risks of the underlying equity securities. The fund's successful use of equity-linked notes will usually depend on the investment adviser's ability to accurately forecast movements in the prices of the underlying securities. Should the prices of the underlying securities move in an unexpected manner, or should the structure of a note respond to market conditions differently than anticipated, the fund may not achieve the anticipated benefits of the investment in the equity-linked note, and the fund may realize losses, which could be significant and could include the fund's entire principal investment in the note.

Equity-linked notes are generally designed for the over-the-counter institutional investment market, and the secondary market for equity-linked notes may be limited. The lack of a liquid secondary market may have an adverse effect on the ability of the fund to accurately value and/or sell the equity-linked notes in its portfolio.

**Washington Mutual Investors Fund and its investment policies —** Washington Mutual Investors Fund has an Eligible List of securities considered appropriate for a prudent investor seeking opportunities for income and growth of principal consistent with common stock investing. Numerous criteria govern which securities may be included on the fund's Eligible List. Currently, those criteria include, for example: (a) a security shall be listed on the New York Stock Exchange ("NYSE") or meet the financial listing requirements of the NYSE (the applicable listing requirements are set forth in Section 1 of the Listed Company Manual of the NYSE); (b) most companies must have fully earned their dividends in at least four of the past five years (with the exception of certain banking institutions) and paid a dividend in at least eight of the past ten years; (c) issuing companies must meet both initial and ongoing market capitalization requirements; and (d) the ratio of current assets to liabilities for most individual companies must be at least 1.5 to 1, or their bonds must be rated at least investment grade by S&P Global Ratings. The investment adviser generates and maintains the Eligible List and selects the fund's investments exclusively from the securities on the Eligible List.

Although the fund generally invests in U.S. companies, the fund may invest up to 10% of its assets in securities of certain companies domiciled outside the United States. The fund may also hold securities of companies domiciled outside the United States when such companies have merged with or otherwise acquired a company in which the fund held shares at the time of the merger.

It is believed that in applying the above disciplines and procedures, the fund makes available to pension and profit-sharing trustees and other fiduciaries a prudent stock investment and a continuity of investment quality which it has always been the policy of the fund to provide. However, fiduciary investment responsibility and the Prudent Investor Rule, pursuant to which a fiduciary is generally required to invest and manage trust assets as a prudent investor would, involve a mixed question of law and fact which cannot be conclusively determined in advance. Moreover, recent changes to the Prudent Investor Rule in some jurisdictions speak to an allocation of funds among a variety of investments. Therefore, each fiduciary should examine the common stock portfolio of the fund to see that it, along with other investments, meets the requirements of the specific trust.

**U.S. Small and Mid Cap Equity Fund and its non-diversified status —** U.S. Small and Mid Cap Equity Fund is a non-diversified investment company which allows the fund to invest a greater percentage of its assets in any one issuer than a diversified investment company. To the extent that the fund invests a larger percentage of its assets in securities of one or more issuers, poor performance by these securities could have a greater adverse impact on the fund's investment results. For the fund to be considered a "diversified" investment company under the Investment Company Act of 1940, as amended, the fund with respect to 75% of its total assets, would be required to limit its investment in

American Funds Insurance Series — Page 36

------

any one issuer (other than the U.S. government) to 5% of the market value of the total assets of the fund or to 10% of the outstanding voting securities of such issuer.

**Cybersecurity risks —** With the increased use of technologies such as the Internet to conduct business, the fund has become potentially more susceptible to operational and information security risks through breaches in cybersecurity. In general, a breach in cybersecurity can result from either a deliberate attack or an unintentional event. Cybersecurity breaches may involve, among other things, "ransomware" attacks, injection of computer viruses or malicious software code, or the use of vulnerabilities in code to gain unauthorized access to digital information systems, networks or devices that are used directly or indirectly by the fund or its service providers through "hacking" or other means. Cybersecurity risks also include the risk of losses of service resulting from external attacks that do not require unauthorized access to the fund's systems, networks or devices. For example, denial-of-service attacks on the investment adviser's or an affiliate's website could effectively render the fund's network services unavailable to fund shareholders and other intended end-users. Any such cybersecurity breaches or losses of service may, among other things, cause the fund to lose proprietary information, suffer data corruption or lose operational capacity, or may result in the misappropriation, unauthorized release or other misuse of the fund's assets or sensitive information (including shareholder personal information or other confidential information), the inability of fund shareholders to transact business, or the destruction of the fund's physical infrastructure, equipment or operating systems. These, in turn, could cause the fund to violate applicable privacy and other laws and incur or suffer regulatory penalties, reputational damage, additional costs (including compliance costs) associated with corrective measures and/or financial loss. While the fund and its investment adviser have established business continuity plans and risk management systems designed to prevent or reduce the impact of cybersecurity attacks, there are inherent limitations in such plans and systems due in part to the ever-changing nature of technology and cybersecurity attack tactics, and there is a possibility that certain risks have not been adequately identified or prepared for.

In addition, cybersecurity failures by or breaches of the fund's third-party service providers (including, but not limited to, the fund's investment adviser, transfer agent, custodian, administrators and other financial intermediaries) may disrupt the business operations of the service providers and of the fund, potentially resulting in financial losses, the inability of fund shareholders to transact business with the fund and of the fund to process transactions, the inability of the fund to calculate its net asset value, violations of applicable privacy and other laws, rules and regulations, regulatory fines, penalties, reputational damage, reimbursement or other compensatory costs and/or additional compliance costs associated with implementation of any corrective measures. The fund and its shareholders could be negatively impacted as a result of any such cybersecurity breaches, and there can be no assurance that the fund will not suffer losses relating to cybersecurity attacks or other informational security breaches affecting the fund's third-party service providers in the future, particularly as the fund cannot control any cybersecurity plans or systems implemented by such service providers.

Cybersecurity risks may also impact issuers of securities in which the fund invests, which may cause the fund's investments in such issuers to lose value.

**Inflation/Deflation risk —** The fund may be subject to inflation and deflation risk. Inflation risk is the risk that the present value of assets or income from investments will be less in the future as inflation decreases the value of money. As inflation increases, the present value of the fund's assets can decline. Deflation risk is the risk that prices throughout the economy decline over time. Deflation or inflation may have an adverse effect on the creditworthiness of issuers and may make issuer default more likely, which may result in a decline in the value of the fund's assets.

**Interfund borrowing and lending —** Pursuant to an exemptive order issued by the U.S. Securities and Exchange Commission, certain funds may lend money to, and borrow money from, other funds advised by Capital Research and Management Company or its affiliates. Such funds will borrow through the program only when the costs are equal to or lower than the costs of bank loans. Such

American Funds Insurance Series — Page 37

------

funds will lend through the program only when the returns are higher than those available from an investment in repurchase agreements. Interfund loans and borrowings normally extend overnight, but can have a maximum duration of seven days. Loans may be called on one day's notice. A fund may have to borrow from a bank at a higher interest rate if an interfund loan is called or not renewed. Any delay in repayment to a lending fund could result in a lost investment opportunity or additional borrowing costs.

**Affiliated investment companies —** Certain funds may purchase shares of certain other investment companies managed by the investment adviser or its affiliates ("Central Funds"). The risks of owning another investment company are similar to the risks of investing directly in the securities in which that investment company invests. Investments in other investment companies could allow a fund to obtain the benefits of a more diversified portfolio than might otherwise be available through direct investments in a particular asset class, and will subject the fund to the risks associated with the particular asset class or asset classes in which an underlying fund invests. However, an investment company may not achieve its investment objective or execute its investment strategy effectively, which may adversely affect the fund's performance. Any investment in another investment company will be consistent with the fund's objective(s) and applicable regulatory limitations. Central Funds do not charge management fees. As a result, the fund does not bear additional management fees when investing in Central Funds, but the fund does bear its proportionate share of Central Fund expenses.

**Securities lending activities** – Certain funds may lend portfolio securities to brokers, dealers or other institutions that provide cash or U.S. Treasury securities as collateral in an amount at least equal to the value of the securities loaned. While portfolio securities are on loan, the fund will continue to receive the equivalent of the interest and the dividends or other distributions paid by the issuer on the securities, as well as a portion of the interest on the investment of the collateral. Additionally, although the fund will not have the right to vote on securities while they are on loan, the fund has a right to consent on corporate actions and a right to recall each loan to vote on proposals, including proposals involving material events affecting securities loaned. The fund has delegated the decision to lend portfolio securities to the investment adviser. The adviser also has the discretion to consent on corporate actions and to recall securities on loan to vote. In the event the adviser deems a corporate action or proxy vote material, as determined by the adviser based on factors relevant to the fund, it will use reasonable efforts to recall the securities and consent to or vote on the matter.

Securities lending involves risks, including the risk that the loaned securities may not be returned in a timely manner or at all, which would interfere with the fund's ability to vote proxies or settle transactions, and/or the risk of a counterparty default. Additionally, the fund may lose money from the reinvestment of collateral received on loaned securities in investments that decline in value, default or do not perform as expected. The fund will make loans only to parties deemed by the fund's adviser to be in good standing and when, in the adviser's judgment, the income earned would justify the risks.

Citibank, N.A. ("Citibank") serves as securities lending agent for the funds that may lend portfolio securities. As the securities lending agent, Citibank administers each such fund's securities lending program pursuant to the terms of a securities lending agent agreement entered into between the fund and Citibank. Under the terms of the agreement, Citibank is responsible for making available to approved borrowers securities from the fund's portfolio. Citibank is also responsible for the administration and management of the fund's securities lending program, including the preparation and execution of an agreement with each borrower governing the terms and conditions of any securities loan, ensuring that securities loans are properly coordinated and documented, ensuring that loaned securities are valued daily and that the corresponding required collateral is delivered by the borrowers, arranging for the investment of collateral received from borrowers, and arranging for the return of loaned securities to the fund in accordance with the fund's instructions or at loan termination. As compensation for its services, Citibank receives a portion of the amount earned by the funds for lending securities.

**Portfolio turnover —** Portfolio changes will be made without regard to the length of time particular investments may have been held. Short-term trading profits are not the funds' objective, and changes in their investments are generally accomplished gradually, though short-term transactions may occasionally be made. Higher portfolio turnover may involve correspondingly greater transaction costs in the form of dealer spreads or brokerage commissions. It may also result in the realization of net capital gains, which are taxable when distributed to shareholders, unless the shareholder is exempt from taxation or his or her account is tax-favored.

Fixed income securities are generally traded on a net basis and usually neither brokerage commissions nor transfer taxes are involved. Transaction costs are usually reflected in the spread between the bid and asked price.

A fund's portfolio turnover rate would equal 100% if each security in the fund's portfolio were replaced once per year. The following table sets forth the portfolio turnover rates for each fund for the fiscal years ended December 31, 2025 and 2024, and the portfolio turnover rates excluding mortgage dollar roll transactions for certain funds for the fiscal years ended December 31, 2025 and 2024. See "Forward commitment, when issued and delayed delivery transactions" above for more information on mortgage dollar rolls. Variations in turnover rate are due to changes in trading activity during the period.

**Fund policies**

All percentage limitations in the following fund policies are considered at the time securities are purchased and are based on a fund's net assets (excluding, for the avoidance of doubt, collateral held in connection with securities lending activities) unless otherwise indicated. None of the following policies involving a maximum percentage of assets will be considered violated unless the excess occurs immediately after, and is caused by, an acquisition by a fund. In managing a fund, a fund's investment adviser may apply more restrictive policies than those listed below.

**Fundamental policies —** The Series has adopted the following policies, which may not be changed without approval by holders of a majority of its outstanding shares. Such majority is currently defined in the Investment Company Act of 1940, as amended (the "1940 Act"), as the vote of the lesser of (*a*) 67% or more of the voting securities present at a shareholder meeting, if the holders of more than 50% of the outstanding voting securities are present in person or by proxy, or (*b*) more than 50% of the outstanding voting securities.

Except where otherwise indicated, the following policies apply to each fund in the Series (please also see "Additional information about fundamental policies" below):

1. Except as permitted by (*i*) the 1940 Act and the rules and regulations thereunder, or other successor law governing the regulation of registered investment companies, or interpretations or modifications thereof by the U.S. Securities and Exchange Commission ("SEC"), SEC staff or other authority of competent jurisdiction, or (*ii*) exemptive or other relief or permission from the SEC, SEC staff or other authority of competent jurisdiction, a fund may not:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;a.Borrow money;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;b.Issue senior securities;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;c.Underwrite the securities of other issuers;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;d.Purchase or sell real estate or commodities;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;e.Make loans; or

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;f.Purchase the securities of any issuer if, as a result of such purchase, a fund's investments would be concentrated in any particular industry.

2. The fund may not invest in companies for the purpose of exercising control or management.

3. For Washington Mutual Investors Fund, the fund may not invest more than 5% of net assets in money market instruments, after allowing for sales of portfolio securities and fund shares within 30 days and the accumulation of cash balances representing undistributed net investment income and realized capital gains, in order to maintain a fully invested portfolio.

**Nonfundamental policies —** The following policy may be changed without shareholder approval:

The fund may not acquire securities of open-end investment companies or unit investment trusts registered under the 1940 Act in reliance on Sections 12(d)(1)(F) or 12(d)(1)(G) of the 1940 Act.

**Additional information about fundamental policies** — The information below is not part of the Series' fundamental policies. This information is intended to provide a summary of what is currently required or permitted by the 1940 Act and the rules and regulations thereunder, or by the interpretive guidance thereof by the SEC or SEC staff, for particular fundamental policies of the Series. Information is also provided regarding the fund's current intention with respect to certain investment practices permitted by the 1940 Act.

For purposes of fundamental policy 1a, the fund may borrow money in amounts of up to 33-1/3% of its total assets from banks for any purpose. Additionally, the fund may borrow up to 5% of its total assets from banks or other lenders for temporary purposes (a loan is presumed to be for temporary purposes if it is repaid within 60 days and is not extended or renewed). The percentage limitations in this policy are considered at the time of borrowing and thereafter. See "General information - Credit facility" in this statement of additional information for more information.

For purposes of fundamental policies 1a and 1e, certain funds may borrow money from, or loan money to, other funds managed by Capital Research and Management Company or its affiliates to the extent permitted by applicable law and an exemptive order issued by the SEC.

For purposes of fundamental policy 1b, a senior security does not include any promissory note or evidence of indebtedness if such loan is for temporary purposes only and in an amount not exceeding 5% of the value of the total assets of the fund at the time the loan is made (a loan is presumed to be for temporary purposes if it is repaid within 60 days and is not extended or renewed). Further, the fund is permitted to enter into derivatives and certain other transactions, notwithstanding the prohibitions and restrictions on the issuance of senior securities under the 1940 Act, in accordance with current SEC rules and interpretations.

For purposes of fundamental policy 1c, the policy will not apply to the fund to the extent the fund may be deemed an underwriter within the meaning of the 1933 Act in connection with the purchase and sale of fund portfolio securities in the ordinary course of pursuing its investment objective(s) and strategies.

For purposes of fundamental policy 1e, the fund may not lend more than 33-1/3% of its total assets, provided that this limitation shall not apply to the fund's purchase of debt obligations, money market instruments and repurchase agreements.

For purposes of fundamental policy 1f, the fund may not invest more than 25% of its total assets in the securities of issuers in a particular industry. This policy does not apply to investments in securities of the United States government, its agencies or instrumentalities or government sponsored entities or repurchase agreements with respect thereto. For purposes of this policy, with respect to a private activity municipal bond the principal and interest payments of which are derived primarily from the assets and revenues of a non-governmental entity, the fund will look to such non-governmental entity to determine the industry to which the investment should be allocated.

For purposes of fundamental policy 3, money market instruments include one or more money market or similar funds managed by the investment adviser or its affiliates.

**Management of the Series**

**Board of trustees and officers**

**Independent trustees<sup>1</sup>**

The Series' nominating and governance committee and board select independent trustees with a view toward constituting a board that, as a body, possesses the qualifications, skills, attributes and experience to appropriately oversee the actions of the Series' service providers, decide upon matters of general policy and represent the long-term interests of fund shareholders. In doing so, they consider the qualifications, skills, attributes and experience of the current board members, with a view toward maintaining a board that is diverse in viewpoint, experience, education and skills.

The Series seeks independent trustees who have high ethical standards and the highest levels of integrity and commitment, who have inquiring and independent minds, mature judgment, good communication skills, and other complementary personal qualifications and skills that enable them to function effectively in the context of the Series' board and committee structure and who have the ability and willingness to dedicate sufficient time to effectively fulfill their duties and responsibilities.

Each independent trustee has a significant record of accomplishments in governance, business, not-for-profit organizations, government service, academia, law, accounting or other professions. Although no single list could identify all experience upon which the Series' independent trustees draw in connection with their service, the following table summarizes key experience for each independent trustee. These references to the qualifications, attributes and skills of the trustees are pursuant to the disclosure requirements of the SEC, and shall not be deemed to impose any greater responsibility or liability on any trustee or the board as a whole. Notwithstanding the accomplishments listed below, none of the independent trustees is considered an "expert" within the meaning of the federal securities laws with respect to information in the Series' registration statement.

<sup>1</sup> Ownership disclosure is made using the following ranges: None; $1 – $10,000; $10,001 – $50,000; $50,001 – $100,000; and Over $100,000. The amounts listed for interested trustees include shares owned through The Capital Group Companies, Inc. retirement plan and/or 401(k) plan, as applicable.

<sup>2</sup> N/A indicates that the listed individual, as of December 31, 2025, was not a trustee of the fund (or, as applicable, other funds in the same family of investment companies as the fund), did not allocate deferred compensation to the fund, or did not participate in the deferred compensation plan.

<sup>3</sup>Shares of the funds may only be owned by purchasing variable annuity and variable life insurance contracts. Each trustee's need for variable annuity or variable life contracts and the role those contracts would play in his or her comprehensive investment portfolio will vary and depend on a number of factors including tax, estate planning, life insurance, alternative retirement plans or other considerations.

<sup>4</sup>Eligible trustees may defer their compensation under a nonqualified deferred compensation plan. Amounts deferred by the trustee accumulate at an earnings rate determined by the total return of one or more American Funds as designated by the trustee.

<sup>5</sup>The funds in the Series are not available for investment in the independent trustees' deferred compensation plan.

**Trustee compensation —** No compensation is paid by the Series to any officer or trustee who is a director, officer or employee of the investment adviser or its affiliates. Except for the independent trustees listed in the "Board of trustees and officers — Independent trustees" table under the "Management of the Series" section in this statement of additional information, all other officers and trustees of the Series are directors, officers or employees of the investment adviser or its affiliates. The board typically meets either individually or jointly with the boards of one or more other such funds with substantially overlapping board membership (in each case referred to as a "board cluster"). The Series typically pays each independent trustee an annual retainer fee based primarily on the total number of board clusters which that independent trustee serves. Board and committee chairs receive additional fees for their services.

The Series and the other funds served by each independent trustee each pay a portion of these fees.

No pension or retirement benefits are accrued as part of Series expenses. Generally, independent trustees may elect, on a voluntary basis, to defer all or a portion of their fees through a deferred compensation plan in effect for the Series. The Series also reimburses certain expenses of the independent trustees.

<sup>1</sup> Amounts may be deferred by eligible trustees under a nonqualified deferred compensation plan adopted by the Series in 1993. Deferred amounts accumulate at an earnings rate determined by the total return of one or more American Funds as designated by the trustees. Compensation shown in this table for the fiscal year ended December 31, 2025 does not include earnings on amounts deferred in previous fiscal years. See footnote 2 to this table for more information.

<sup>2</sup> Since the deferred compensation plan's adoption, the total amount of deferred compensation accrued by the Series (plus earnings thereon) through the end of the 2025 fiscal year for participating trustees is as follows: Francisco G. Cigarroa ($168,656), Nariman Farvardin ($676,191), Jennifer C. Feikin ($206,613), Merit E. Janow ($53,761), Margaret Spellings ($558,496), Alexandra Trower ($580,410) and Paul S. Williams ($115,942). Amounts deferred and accumulated earnings thereon are not funded and are general unsecured liabilities of the Series until paid to the trustees .

**Series organization and the board of trustees —** The Series, an open-end investment company, was organized as a Massachusetts business trust on September 13, 1983. At a meeting of the Series' shareholders on November 24, 2009, shareholders approved the reorganization of the Series to a Delaware statutory trust. However, the Series reserved the right to delay implementing the reorganization and has elected to do so. A summary comparison of the governing documents and state laws affecting the Delaware statutory trust and the current form of organization of the Series can be found in the proxy statement for the Series dated August 28, 2009, which is available on the SEC's website at sec.gov.

All Series operations are supervised by its board of trustees, which meets periodically and performs duties required by applicable state and federal laws. Independent board members are paid certain fees for services rendered to the Series as described above. They may elect to defer all or a portion of these fees through a deferred compensation plan in effect for the Series.

Massachusetts common law provides that a trustee of a Massachusetts business trust owes a fiduciary duty to the trust and must carry out his or her responsibilities as a trustee in accordance with that fiduciary duty. Generally, a trustee will satisfy his or her duties if he or she acts in good faith and uses ordinary prudence.

The Series currently consists of separate funds which have separate assets and liabilities, and invest in separate investment portfolios. The board of trustees may create additional funds in the future. Income, direct liabilities and direct operating expenses of a fund will be allocated directly to that fund and general liabilities and expenses of the Series will be allocated among the funds in proportion to the total net assets of each fund.

Each fund has Class 1, Class 1A, Class 2 and Class 4 shares. In addition, Growth Fund, EUPAC Fund, Growth-Income Fund, Asset Allocation Fund, American High-Income Trust, Ultra-Short Bond Fund and U.S. Government Securities Fund have Class 3 shares. Other funds in the series have Class P1 and/or Class P2 shares. The shares of each class represent an interest in the same investment portfolio. Each class has equal rights as to voting, redemption, dividends and liquidation, except that each class bears different distribution expenses and other expenses properly attributable to the particular class as approved by the board of trustees and set forth in the Series' amended and restated rule 18f-3 Plan. Class 1A, Class 2, Class 3 and Class 4 shareholders have exclusive voting rights with respect to their respective rule 12b-1 Plans adopted in connection with the distribution of Class 1A, Class 2, Class 3 and Class 4 shares. Class 1A and Class 4 shareholders have exclusive voting rights with respect to their Insurance Administrative Services Plans. Shares of each Class of the Series vote together on matters that affect all classes in substantially the same manner. Each class votes as a class on matters that affect that class alone.

The Series does not hold annual meetings of shareholders. However, significant matters that require shareholder approval, such as certain elections of board members or a change in a fundamental investment policy, will be presented to shareholders at a meeting called for such purpose. Shareholders have one vote per share owned. At the request of the holders of at least 10% of the shares, the Series will hold a meeting at which any member of the board could be removed by a majority vote.

The Series' declaration of trust and by-laws, as well as separate indemnification agreements that the Series has entered into with independent trustees, provide in effect that, subject to certain conditions, the Series will indemnify its officers and trustees against liabilities or expenses actually and reasonably incurred by them relating to their service to the Series. However, trustees are not protected from liability by reason of their willful misfeasance, bad faith, gross negligence or reckless disregard of the duties involved in the conduct of their office.

**Leadership structure —** The board's chair is currently an independent trustee who is not an "interested person" of the Series within the meaning of the 1940 Act. The board has determined that an independent chair facilitates oversight and enhances the effectiveness of the board. The independent chair's duties include, without limitation, generally presiding at meetings of the board, approving board meeting schedules and agendas, leading meetings of the independent trustees in executive session, facilitating communication with committee chairs, and serving as the principal independent trustee contact for Series management and counsel to the independent trustees and the fund.

**Risk oversight —** Day-to-day management of the Series, including risk management, is the responsibility of the Series' contractual service providers, including the Series' investment adviser, principal underwriter/distributor and transfer agent. Each of these entities is responsible for specific portions of the Series' operations, including the processes and associated risks relating to the funds' investments, integrity of cash movements, financial reporting, operations and compliance. The board of trustees oversees the service providers' discharge of their responsibilities, including the processes they use to manage relevant risks. In that regard, the board receives reports regarding the operations of the Series' service providers, including risks. For example, the board receives reports from investment professionals regarding risks related to the funds' investments and trading. The board also receives compliance reports from the Series and the investment adviser's chief compliance officers addressing certain areas of risk.

Committees of the Series board, which are comprised of independent board members, none of whom is an "interested person" of the fund within the meaning of the 1940 Act, as well as joint committees of independent board members of funds managed by Capital Research and Management Company, also explore risk management procedures in particular areas and then report back to the full board. For example, the Series' audit committee oversees the processes and certain attendant risks relating to financial reporting, valuation of fund assets, and related controls. Similarly, a joint review and advisory committee oversees certain risk controls relating to the fund's transfer agency services.

Not all risks that may affect the Series can be identified or processes and controls developed to eliminate or mitigate their effect. Moreover, it is necessary to bear certain risks (such as investment-related risks) to achieve each fund's objectives. As a result of the foregoing and other factors, the ability of the Series' service providers to eliminate or mitigate risks is subject to limitations.

American Funds Insurance Series — Page 59

**Committees of the board of trustees —** The Series has an audit committee comprised of Vanessa C.L. Chang, Francisco G. Cigarroa, John G. Freund, Leslie Stone Heisz, Sharon I. Meers, Kennth M. Simril, Christopher E. Stone and Paul S. Williams. The committee provides oversight regarding the Series' accounting and financial reporting policies and practices, its internal controls and the internal controls of the Series' principal service providers. The committee acts as a liaison between the Series' independent registered public accounting firm and the full board of trustees. The audit committee held five meetings during the 2025 fiscal year.

The Series has a contracts committee comprised of all of its independent board members. The committee's principal function is to request, review and consider the information deemed necessary to evaluate the terms of certain agreements between the Series and its investment adviser or the investment adviser's affiliates, such as the Investment Advisory and Service Agreement and plan of distribution adopted pursuant to rule 12b-1 under the 1940 Act, that the Series may enter into, renew or continue, and to make its recommendations to the full board of trustees on these matters. The contracts committee held one meeting during the 2025 fiscal year.

The Series has a nominating and governance committee comprised of Nariman Farvardin, Jennifer C. Feikin, Margaret Spellings and Alexandra Trower. The committee periodically reviews such issues as the board's composition, responsibilities, committees, compensation and other relevant issues, and recommends any appropriate changes to the full board of trustees. The committee also coordinates annual self-assessments of the board and evaluates, selects and nominates independent trustee candidates to the full board of trustees. While the committee normally is able to identify from its own and other resources an ample number of qualified candidates, it will consider shareholder suggestions of persons to be considered as nominees to fill future vacancies on the board. Such suggestions must be sent in writing to the nominating and governance committee of the Series, addressed to the Series' secretary, and must be accompanied by complete biographical and occupational data on the prospective nominee, along with a written consent of the prospective nominee for consideration of his or her name by the committee. The nominating and governance committee held two meetings during the 2025 fiscal year.

**Proxy voting procedures and principles —** The funds' investment adviser, in consultation with the Series' board, has adopted Proxy Voting Procedures and Principles (the "Principles") with respect to voting proxies of securities held by the funds and other funds advised by the investment adviser or its affiliates. The Principles are reasonably designed to ensure that proxies are voted solely in accordance with the financial interest of the clients of the investment adviser or its affiliates and the shareholders of the funds advised or managed by the investment adviser or its affiliates. The complete text of the Principles is available at capitalgroup.com. Final voting authority is held by a committee of the appropriate equity investment division of the investment adviser under authority delegated by the Series' board. Therefore, if more than one fund invests in the same company, they may vote differently on the same proposal. The boards of funds advised by Capital Research and Management Company and its affiliates have established a Joint Proxy Committee ("JPC") composed of independent board members who serve as representatives from each applicable fund board. The JPC's role is to facilitate appropriate oversight of the proxy voting process and provide valuable input on corporate governance and related matters.

The Principles provide an important framework for analysis and decision-making by all funds. However, they are not exhaustive and do not address all potential issues. The Principles provide a certain amount of flexibility so that all relevant facts and circumstances can be considered in connection with every vote. As a result, each proxy received is voted on a case-by-case basis considering the specific circumstances of each proposal. The voting process reflects the funds' understanding of the company's business, its management and its relationship with shareholders over time. In all cases, long-term value creation and the investment objectives and policies of the funds managed by the investment adviser remain the focus.

American Funds Insurance Series — Page 60

------

The investment adviser seeks to vote all U.S. proxies. Proxies for companies outside the United States are also voted where there is sufficient time and information available, taking into account distinct market practices, regulations and laws, and types of proposals presented in each country. Where there is insufficient proxy and meeting agenda information available, the investment adviser will generally vote against such proposals in the interest of encouraging improved disclosure for investors. The investment adviser may not exercise its voting authority if voting would impose costs on clients, including opportunity costs. For example, certain regulators have granted investment limit relief to the investment adviser and its affiliates, conditioned upon limiting voting power to specific voting ceilings. To comply with these voting ceilings, the investment adviser will scale back its votes across all funds and accounts it manages on a pro rata basis based on assets. In addition, certain countries impose restrictions on the ability of shareholders to sell shares during the proxy solicitation period. The investment adviser may choose, due to liquidity issues, not to expose the funds and accounts it manages to such restrictions and may not vote some (or all) shares. Finally, the investment adviser may determine not to recall securities on loan to exercise its voting rights when it determines that the cost of doing so would exceed the benefits to clients or that the vote would not have a material impact on the investment. Proxies with respect to securities on loan through client-directed lending programs are not available to vote and therefore are not voted.

After a proxy statement is received, the investment adviser's stewardship and engagement team prepares a summary of the proposals contained in the proxy statement.

Investment analysts are generally responsible for making voting recommendations for their investment division on significant votes that relate to companies in their coverage areas. Analysts also have the opportunity to review initial recommendations made by the investment adviser's stewardship and engagement team. Depending on the vote recommendation, a second opinion may be made by a proxy coordinator (an investment professional with experience in corporate governance and proxy voting matters) within the appropriate investment division, based on knowledge of the Principles and familiarity with proxy-related issues. Each of the investment adviser's equity investment divisions has its own proxy voting committee, which is made up of investment professionals within each division. Each division's proxy voting committee retains final authority for voting decisions made by such division. In cases where a fund is co-managed and a security is held by more than one of the investment adviser's equity investment divisions, the divisions may develop different voting recommendations for individual ballot proposals. If this occurs, and if permitted by local market conventions, the fund's position will generally be voted proportionally by divisional holding, according to their respective decisions. Otherwise, the outcome will be determined by the equity investment division or divisions with the larger position in the security as of the record date for the shareholder meeting.

In addition to our proprietary proxy voting, governance and executive compensation research, Capital Research and Management Company may utilize research provided by third-party advisory firms on a case-by-case basis. It does not, as a policy, follow the voting recommendations provided by these firms. It periodically assesses the information provided by the advisory firms and reports to the applicable governance committees that provide oversight of the application of the Principles.

From time to time the investment adviser may vote proxies issued by, or on proposals sponsored or publicly supported by *(a)* a client with substantial assets managed by the investment adviser or its affiliates, *(b)* an entity with a significant business relationship with The Capital Group Companies, Inc. or its affiliates, or *(c)* a company with a director of an American Fund on its board (each referred to as an "Interested Party"). Other persons or entities may also be deemed an Interested Party if facts or circumstances appear to give rise to a potential conflict.

The investment adviser has developed procedures to identify and address instances when a vote could appear to be influenced by such a relationship. Each equity investment division of the investment adviser has established a Special Review Committee ("SRC") of senior investment professionals and legal and compliance professionals with oversight of potentially conflicted matters.

American Funds Insurance Series — Page 61

------

If a potential conflict is identified according to the procedure above, the SRC will take appropriate steps to address the conflict of interest. These steps may include engaging an independent third party to review the proxy and using the Principles to provide an independent voting recommendation to the investment adviser for vote execution. The investment adviser will generally follow the third party's recommendation, except when it believes the recommendation is inconsistent with the investment adviser's fiduciary duty to its clients. Occasionally, it may not be feasible to engage the third party to review the matter due to compressed timeframes or other operational issues. In this case, the SRC will take appropriate steps to address the conflict of interest, including reviewing the proxy after being provided with a summary of any relevant communications with the Interested Party, the rationale for the voting decision, information on the organization's relationship with the Interested Party and any other pertinent information.

Information regarding how the funds voted proxies relating to portfolio securities during the 12-month period ended June 30 of each year will be available on or about September 1 of such year (*a*) without charge, upon request by calling American Funds Service Company at (800) 421-4225, (*b*) on the Capital Group website and (*c*) on the SEC's website at sec.gov.

The following summary sets forth the general positions of the investment adviser on various proposals. A copy of the full Principles is available upon request, free of charge, by calling American Funds Service Company or visiting the Capital Group website.

**Director matters —** The election of a company's slate of nominees for director generally is supported. Votes may be withheld for some or all of the nominees if this is determined to be in the best interest of shareholders or if, in the opinion of the investment adviser, such nominee has not fulfilled his or her fiduciary duty. In making this determination, the investment adviser considers, among other things, a nominee's potential conflicts of interest, track record (whether in the current board seat or in previous executive or director roles) with respect to shareholder protection and value creation as well as their capacity for full engagement on board matters. The investment adviser generally supports a breadth of experience and perspectives among board members, and the separation of the chairman and CEO positions.

**Governance provisions —** Proposals to declassify a board (elect all directors annually) generally are supported based on the belief that this increases the directors' sense of accountability to shareholders. Proposals for cumulative voting generally are supported in order to promote management and board accountability and an opportunity for leadership change. Proposals designed to make director elections more meaningful, either by requiring a majority vote or by requiring any director receiving more withhold votes than affirmative votes to tender his or her resignation, generally are supported.

**Shareholder rights —** Proposals to repeal an existing poison pill generally are supported. (There may be certain circumstances, however, when a proxy voting committee of a fund or an investment division of the investment adviser believes that a company needs to maintain anti-takeover protection.) Proposals to eliminate the right of shareholders to act by written consent or to take away a shareholder's right to call a special meeting typically are not supported.

**Compensation and benefit plans —** Equity incentive plans are complicated, and many factors are considered in evaluating a plan. Each plan is evaluated based on protecting shareholder interests and a knowledge of the company and its management. Considerations include the pricing (or repricing) of options awarded under the plan and the impact of dilution on existing shareholders from past and future equity awards. Compensation packages should be structured to attract, motivate and retain existing employees and qualified directors; in addition, they should be aligned with the long-term success of the company and the enhancement of shareholder value.

American Funds Insurance Series — Page 62

------

**Routine matters —** The ratification of auditors, procedural matters relating to the annual meeting and changes to company name are examples of items considered routine. Such items generally are voted in favor of management's recommendations unless circumstances indicate otherwise.

**Shareholder proposals on environmental and social issues —** The investment adviser believes environmental and social issues present investment risks and opportunities that can shape a company's long-term financial sustainability. Shareholder proposals, including those relating to social and environmental issues, are evaluated in terms of their materiality to the company and its ability to generate long-term value in light of the company's business model specific operating context. The investment adviser generally supports transparency and standardized disclosure, particularly that which leverages existing regulatory reporting or industry best practices. With respect to environmental matters, this includes disclosures aligned with industry standards and reporting on sustainability issues that are material to investment analysis. With respect to social matters, the investment adviser encourages companies to disclose the composition of the workforce in a regionally appropriate manner. The investment adviser supports relevant reporting and disclosure that is consistent with broadly applicable standards.

**Principal fund shareholders —** The following tables identify those investors who own of record, or are known by the Series to own beneficially, 5% or more of any class of a fund's shares as of the opening of business on April 1, 2026.

**Investment adviser —** Capital Research and Management Company, the Series' investment adviser, founded in 1931, maintains research facilities in the United States and abroad (Geneva, Hong Kong, London, Los Angeles, Mumbai, New York, San Francisco, Singapore, Tokyo, Toronto and Washington, D.C.). These facilities are staffed with experienced investment professionals. The investment adviser is located at 333 South Hope Street, Los Angeles, CA 90071. It is a wholly owned subsidiary of The Capital Group Companies, Inc., a holding company for several investment management subsidiaries. Capital Research and Management Company manages equity assets through three equity investment divisions and fixed income assets through its fixed income investment division, Capital Fixed Income Investors. The three equity investment divisions — Capital World Investors, Capital Research Global Investors and Capital International Investors — make investment decisions independently of one another. Portfolio managers in Capital International Investors rely on a research team that also provides investment services to institutional clients and other accounts advised by affiliates of Capital Research and Management Company. The investment adviser, which is deemed under the Commodity Exchange Act (the "CEA") to be the operator of certain funds, has claimed an exclusion from the definition of the term commodity pool operator under the CEA with respect to each fund and, therefore, is not subject to registration or regulation as such under the CEA with respect to the funds.

The investment adviser has adopted policies and procedures that address issues that may arise as a result of an investment professional's management of the funds and other funds and accounts. Potential issues could involve allocation of investment opportunities and trades among funds and accounts, use of information regarding the timing of fund trades, investment professional compensation and voting relating to portfolio securities. The investment adviser believes that its policies and procedures are reasonably designed to address these issues.

**Compensation of investment professionals —** As described in the prospectus, the investment adviser uses a system of multiple portfolio managers in managing fund assets. In addition, Capital Research and Management Company's investment analysts may make investment decisions with respect to a portion of a fund's portfolio within their research coverage.

Portfolio managers and investment analysts are paid competitive salaries by Capital Research and Management Company. In addition, they may receive bonuses based on their individual portfolio results. Investment professionals also may participate in profit-sharing plans. The relative mix of compensation represented by bonuses, salary and profit-sharing plans will vary depending on the individual's portfolio results, contributions to the organization and other factors.

To encourage a long-term focus, bonuses based on investment results are calculated by comparing total investment returns to relevant benchmarks over the most recent one-, three-, five- and eight-year periods, with increasing weight placed on each succeeding measurement period. For portfolio managers, benchmarks may include measures of the marketplaces in which the fund invests and measures of the results of comparable mutual funds. For investment analysts, benchmarks may include relevant market measures and appropriate industry or sector indexes reflecting their areas of expertise. Capital Research and Management Company makes periodic subjective assessments of analysts' contributions to the investment process and this is an element of their overall compensation. The investment results of each of the funds' portfolio managers may be measured against one or more benchmarks, depending on his or her investment focus, such as:

SMALLCAP World Fund — (i) MSCI USA Small Cap Index, (ii) MSCI All Country World Small Cap Index Net to US, (iii) MSCI All Country World ex USA Small Cap Index Net to US, and (iv) a peer group average consisting of funds that disclose investment objectives and strategies comparable to those of the fund; and

American Funds Insurance Series — Page 65

------

EUPAC Fund — MSCI All Country World ex USA Index Net to US and a peer group average consisting of funds that disclose investment objectives and strategies comparable to those of the fund

From time to time, Capital Research and Management Company may adjust or customize these benchmarks to better reflect the investment objective(s) of the fund and/or the universe of comparably managed funds of competitive investment management firms.

**Portfolio manager fund holdings and management of other accounts —** Shares of the funds may only be owned by purchasing variable annuity and variable life insurance contracts. Each portfolio manager's need for variable annuity or variable life insurance contracts and the role those contracts would play in his or her comprehensive investment portfolio will vary and depend on a number of factors including tax, estate planning, life insurance, alternative retirement plans or other considerations. The portfolio managers have determined that variable insurance or annuity contracts do not meet their current needs. Consequently, they do not hold shares of the funds.

Portfolio managers may also manage assets in other registered investment companies advised by Capital Research and Management Company or its affiliates. Other managed accounts as of the end of American Funds Insurance Series' most recently completed fiscal year are listed as follows:

**Investment Advisory and Service Agreement —** The Investment Advisory and Service Agreement (the "Agreement") between the Series and the investment adviser will continue in effect until April 30, 2027, unless sooner terminated, and may be renewed from year to year thereafter, provided that any such renewal has been specifically approved at least annually by (*a*) the board of trustees, or by the vote of a majority (as defined in the 1940 Act) of the outstanding voting securities of the applicable Series, and (*b*) the vote of a majority of trustees who are not parties to the Agreement or interested persons (as defined in the 1940 Act) of any such party, in accordance with applicable laws and regulations. The Agreement provides that the investment adviser has no liability to the Series for its acts or omissions in the performance of its obligations to the Series not involving willful misconduct, bad faith, gross negligence or reckless disregard of its obligations under the Agreement. The Agreement also provides that either party has the right to terminate it, without penalty, upon 60 days' written notice to the other party, and that the Agreement automatically terminates in the event of its assignment (as defined in the 1940 Act). In addition, the Agreement provides that the investment adviser may delegate all, or a portion of, its investment management responsibilities to one or more subsidiary advisers approved by the Series' board, pursuant to an agreement between the investment adviser and such subsidiary. Any such subsidiary adviser will be paid solely by the investment adviser out of its fees.

**Administrative services —** The investment adviser and its affiliates provide certain administrative services for shareholders of the Series' Class 1, 1A, 2, 3 and 4 shares. Administrative services are provided by the investment adviser and its affiliates to help assist third parties providing non-distribution services to fund shareholders. These services include providing in-depth information on the fund and market developments that impact fund investments. Administrative services also include, but are not limited to, coordinating, monitoring and overseeing third parties that provide services to Series shareholders.

These services are provided pursuant to an Administrative Services Agreement (the "Administrative Agreement") between the Series and the investment adviser relating to the Series' Class 1, 1A, 2, 3 and 4 shares. The Administrative Agreement will continue in effect until April 30, 2027, unless sooner renewed or terminated, and may be renewed from year to year thereafter, provided that any such renewal has been specifically approved by the vote of a majority of the members of the Series' board who are not parties to the Administrative Agreement or interested persons (as defined in the 1940 Act) of any such party. The Series may terminate the Administrative Agreement at any time by vote of a majority of independent board members. The investment adviser has the right to terminate the Administrative Agreement upon 60 days' written notice to the Series. The Administrative Agreement automatically terminates in the event of its assignment (as defined in the 1940 Act).

The Administrative Services Agreement between the fund and the investment adviser provides the fund the ability to charge an administrative services fee of .05% for all share classes. The investment adviser receives an administrative services fee at the annual rate of .03% of the average daily net assets of the fund (which could be increased as noted above) for its provision of administrative services. Administrative services fees are paid monthly and accrued daily.

**Plans of distribution —** The Series has adopted plans of distribution (the "Plans") for its Class 1A, Class 2 , Class 3 and Class 4 shares, pursuant to rule 12b-1 under the 1940 Act. As required by rule 12b-1, the Plans have been approved by a majority of the entire board of trustees, and separately by a majority of the trustees who are not "interested persons" of the Series and who have no direct or indirect financial interest in the operation of the Plans. Potential benefits of the Plans to the Series include benefits to the investment process from growth or stability of assets and maintenance of a financially healthy management organization. The selection and nomination of trustees who are not "interested persons" of the Series is committed to the discretion of the trustees who are not "interested persons" during the existence of the Plans. The Plans are reviewed quarterly and must be renewed annually by the board of trustees.

Under the Plans, the Series will pay to insurance company contract issuers .25% of each fund's average net assets annually (Class 2 and Class 4 shares) or .18% of each fund's average net assets annually (Class 3 shares) to finance any distribution activity which is primarily intended to benefit the Class 2, Class 3 and/or Class 4 shares of the Series, respectively, provided that the board of trustees of the Series has approved the categories of expenses for which payment is being made. Under the Plan for Class 1A shares, the Series may expend up to .25% of the assets of Class 1A shares; however, the board of trustees has not authorized any payments on Class 1A assets pursuant to the Plan for Class 1A shares. Payments made pursuant to the Plans will be used by insurance company contract issuers to pay a continuing annual service or distribution fee to dealers on the value of all variable annuity and variable life insurance contract payments for account-related services provided to existing shareholders. During the fiscal year ended December 31, 2025, the Series incurred distribution expenses for Class 2 shares of $145,649,000, for Class 3 shares of $905,000 and for Class 4 shares of $60,095,000 payable to certain life insurance companies under the respective Plans. Accrued and unpaid distribution expenses were $12,754,000 for Class 2 shares, $81,000 for Class 3 shares and $5,540,000 for Class 4 shares.

**Insurance administration fee —** The insurance companies for which the fund's Class 1A and Class 4 shares are available provide certain administrative services for the separate accounts that hold the shares of the fund and the contractholders for which the shares of the fund are beneficially owned as underlying investments of such contractholders annuities. These services include, but are not limited to, record maintenance, shareholder communications and transactional services.

These services are provided pursuant to Insurance Administrative Services Plans adopted by the Series relating to the fund's Class 1A and Class 4 shares. Under these plans, the insurance company receives .25% of the fund's average daily net assets attributable to Class 1A and Class 4 shares, respectively. During the fiscal year ended December 31, 2025, the Series incurred insurance administration fees of $3,085,000 for Class 1A and $60,093,000 for Class 4 shares.

**Execution of portfolio transactions**

The investment adviser places orders with broker-dealers for the fund's portfolio transactions. Purchases and sales of equity securities on a securities exchange or an over-the-counter market are effected through broker-dealers who receive commissions for their services. Generally, commissions relating to securities traded on foreign exchanges will be higher than commissions relating to securities traded on U.S. exchanges and may not be subject to negotiation. Equity securities may also be purchased from underwriters at prices that include underwriting fees. Purchases and sales of fixed income securities are generally made with an issuer or a primary market maker acting as principal with no stated brokerage commission. The price paid to an underwriter for fixed income securities includes underwriting fees. Prices for fixed income securities in secondary trades usually include undisclosed compensation to the market maker reflecting the spread between the bid and ask prices for the securities.

In selecting broker-dealers, the investment adviser strives to obtain "best execution" (the most favorable total price reasonably attainable under the circumstances) for the fund's portfolio transactions, taking into account a variety of factors. These factors include the size and type of transaction, the nature and character of the markets for the security to be purchased or sold, the cost, quality, likely speed and reliability of execution and settlement, the broker-dealer's or execution venue's ability to offer liquidity and anonymity and the trade-off between market impact and opportunity costs. The investment adviser considers these factors, which involve qualitative judgments, when selecting broker-dealers and execution venues for fund portfolio transactions. The investment adviser views best execution as a process that should be evaluated over time as part of an overall relationship with particular broker-dealer firms. The investment adviser and its affiliates negotiate commission rates with broker-dealers based on what they believe is reasonably necessary to obtain best execution. They seek, on an ongoing basis, to determine what the reasonable levels of commission rates for execution services are in the marketplace, taking various considerations into account, including the extent to which a broker-dealer has put its own capital at risk, historical commission rates and commission rates that other institutional investors are paying. The fund does not consider the investment adviser as having an obligation to obtain the lowest commission rate available for a portfolio transaction to the exclusion of price, service and qualitative considerations. Brokerage commissions are only a small part of total execution costs and other factors, such as market impact and speed of execution, contribute significantly to overall transaction costs.

The investment adviser may execute portfolio transactions with broker-dealers who provide certain brokerage and/or investment research services to it but only when in the investment adviser's judgment the broker-dealer is capable of providing best execution for that transaction. The investment adviser makes decisions for procurement of research separately and distinctly from decisions on the choice of brokerage and execution services. The receipt of these research services permits the investment adviser to supplement its own research and analysis and makes available the views of, and information from, individuals and the research staffs of other firms. Such views and information may be provided in the form of written reports, telephone contacts and meetings with securities analysts. These services may include, among other things, reports and other communications with respect to individual companies, industries, countries and regions, economic, political and legal developments, as well as scheduling meetings with corporate executives and seminars and conferences related to relevant subject matters. Research services that the investment adviser receives from broker-dealers may be used by the investment adviser in servicing the fund and other funds and accounts that it advises; however, not all such services will necessarily benefit the fund.

The investment adviser bears the cost of all third-party investment research services for all client accounts it advises. However, in order to compensate certain U.S. broker-dealers for research consumed, and valued, by the investment adviser's investment professionals, the investment adviser continues to operate a limited commission sharing arrangement with commissions on equity trades for certain registered investment companies it advises. The investment adviser voluntarily reimburses such

American Funds Insurance Series — Page 81

------

registered investment companies for all amounts collected into the commission sharing arrangement. In order to operate the commission sharing arrangement, the investment adviser may cause such registered investment companies to pay commissions in excess of what other broker-dealers might have charged for certain portfolio transactions in recognition of brokerage and/or investment research services. In this regard, the investment adviser has adopted a brokerage allocation procedure consistent with the requirements of Section 28(e) of the Securities Exchange Act of 1934. Section 28(e) permits the investment adviser and its affiliates to cause an account to pay a higher commission to a broker-dealer to compensate the broker-dealer or another service provider for certain brokerage and/or investment research services provided to the investment adviser and its affiliates, if the investment adviser and each affiliate makes a good faith determination that such commissions are reasonable in relation to the value of the services provided by such broker-dealer to the investment adviser and its affiliates in terms of that particular transaction or the investment adviser's overall responsibility to the fund and other accounts that it advises. Certain brokerage and/or investment research services may not necessarily benefit all accounts paying commissions to each such broker-dealer; therefore, the investment adviser and its affiliates assess the reasonableness of commissions in light of the total brokerage and investment research services provided to the investment adviser and its affiliates. Further, investment research services may be used by all investment associates of the investment adviser and its affiliates, regardless of whether they advise accounts with trading activity that generates eligible commissions.

In accordance with their internal brokerage allocation procedure, the investment adviser and its affiliates periodically assess the brokerage and investment research services provided by each broker-dealer and each other service provider from which they receive such services. As part of its ongoing relationships, the investment adviser and its affiliates routinely meet with firms to discuss the level and quality of the brokerage and research services provided, as well as the value and cost of such services. In valuing the brokerage and investment research services the investment adviser and its affiliates receive from broker-dealers and other research providers in connection with its good faith determination of reasonableness, the investment adviser and its affiliates take various factors into consideration, including the quantity, quality and usefulness of the services to the investment adviser and its affiliates. Based on this information and applying their judgment, the investment adviser and its affiliates set an annual research budget.

Research analysts and portfolio managers periodically participate in a research poll to determine the usefulness and value of the research provided by individual broker-dealers and research providers. Based on the results of this research poll, the investment adviser and its affiliates may, through commission sharing arrangements with certain broker-dealers, direct a portion of commissions paid to a broker-dealer by the fund and other registered investment companies managed by the investment adviser or its affiliates to be used to compensate the broker-dealer and/or other research providers for research services they provide. While the investment adviser and its affiliates may negotiate commission rates and enter into commission sharing arrangements with certain broker-dealers with the expectation that such broker-dealers will be providing brokerage and research services, none of the investment adviser, any of its affiliates or any of their clients incurs any obligation to any broker-dealer to pay for research by generating trading commissions. The investment adviser and its affiliates negotiate prices for certain research that may be paid through commission sharing arrangements or by themselves with cash.

When executing portfolio transactions in the same equity security for the funds and accounts, or portions of funds and accounts, over which the investment adviser, through its equity investment divisions, has investment discretion, each investment division within the adviser and its affiliates normally aggregates its respective purchases or sales and executes them as part of the same transaction or series of transactions. When executing portfolio transactions in the same fixed income security for the fund and the other funds or accounts over which it or one of its affiliated companies has investment discretion, the investment adviser normally aggregates such purchases or sales and executes them as part of the same transaction or series of transactions. The objective of aggregating

American Funds Insurance Series — Page 82

------

purchases and sales of a security is to allocate executions in an equitable manner among the funds and other accounts that have concurrently authorized a transaction in such security. The investment adviser and its affiliates serve as investment adviser for certain accounts that are designed to be substantially similar to another account. This type of account will often generate a large number of relatively small trades when it is rebalanced to its reference fund due to differing cash flows or when the account is initially started up. The investment adviser may not aggregate program trades or electronic list trades executed as part of this process. Non-aggregated trades performed for these accounts will be allocated entirely to that account. This is done only when the investment adviser believes doing so will not have a material impact on the price or quality of other transactions.

The investment adviser currently owns a minority interest in IEX Group and alternative trading systems, Luminex ATS and LeveL ATS (through a minority interest in their common parent holding company). The investment adviser, or brokers with which the investment adviser places orders, may place orders on these or other exchanges or alternative trading systems in which it, or one of its affiliates, has an ownership interest, provided such ownership interest is less than five percent of the total ownership interests in the entity. The investment adviser is subject to the same best execution obligations when trading on any such exchange or alternative trading systems.

Purchase and sale transactions may be effected directly among and between certain funds or accounts advised by the investment adviser or its affiliates, including the fund. The investment adviser maintains cross-trade policies and procedures and places a cross-trade only when such a trade is in the best interest of all participating clients and is not prohibited by the participating funds' or accounts' investment management agreement or applicable law.

The investment adviser may place orders for the fund's portfolio transactions with broker-dealers who have sold shares of the funds managed by the investment adviser or its affiliated companies; however, it does not consider whether a broker-dealer has sold shares of the funds managed by the investment adviser or its affiliated companies when placing any such orders for the fund's portfolio transactions.

Purchases and sales of futures contracts for the fund will be effected through executing brokers and FCMs that specialize in the types of futures contracts that the fund expects to hold. The investment adviser will use reasonable efforts to choose executing brokers and FCMs capable of providing the services necessary to obtain the most favorable price and execution available. The full range and quality of services available will be considered in making these determinations. The investment adviser will monitor the executing brokers and FCMs used for purchases and sales of futures contracts for their ability to execute trades based on many factors, such as the sizes of the orders, the difficulty of executions, the operational facilities of the firm involved and other factors.

Forward currency contracts are traded directly between currency traders (usually large commercial banks) and their customers. The cost to the fund of engaging in such contracts varies with factors such as the currency involved, the length of the contract period and the market conditions then prevailing. Because such contracts are entered into on a principal basis, their prices usually include undisclosed compensation to the market maker reflecting the spread between the bid and ask prices for the contracts. The fund may incur additional fees in connection with the purchase or sale of certain contracts.

**Disclosure of portfolio holdings**

The Series' investment adviser, on behalf of the funds, has adopted policies and procedures with respect to the disclosure of information about the funds' portfolio securities. These policies and procedures have been reviewed by the Series' board of trustees, and compliance will be periodically assessed by the board in connection with reporting from the Series' Chief Compliance Officer.

Under these policies and procedures a complete list of portfolio holdings of each fund available for public disclosure, dated as of the end of each calendar quarter, is permitted to be posted on the Capital Group website (capitalgroup.com/afis) no earlier than the 10th day after such calendar quarter. In practice, the publicly disclosed portfolio is typically posted on the Capital Group website within 30 days after the end of the calendar quarter. The publicly disclosed portfolio may exclude certain securities when deemed to be in the best interest of the fund as permitted by applicable regulations. In addition, the fund's list of top 10 portfolio holdings measured by percentage of net assets, dated as of the end of each calendar month, is permitted to be posted on the Capital Group website no earlier than the 10th day after such month for equity securities, and no earlier than the 30<sup>th</sup> day after such month for fixed income securities. The fund's list of top 10 portfolio holdings for equity and fixed income securities is permitted to be posted no earlier than the 10<sup>th</sup> day after the final month of each calendar quarter. For multi-asset funds, the fund's list of top 10 portfolio holdings for equity and fixed income securities is permitted to be posted each month, no earlier than the 10th day after such month. Such portfolio holdings information may be disclosed to any person pursuant to an ongoing arrangement to disclose portfolio holdings information to such person no earlier than one day after the day on which the information is posted on the Capital Group website. The investment adviser may disclose individual holdings more frequently on the Capital Group website if it determines it is in the best interest of the fund.

Certain intermediaries are provided additional information about the fund's management team, including information on the fund's portfolio securities they have selected. This information is provided to larger intermediaries that require the information to make the fund available for investment on the firm's platform. Intermediaries receiving the information are required to keep it confidential and use it only to analyze the fund.

The Series' custodian, outside counsel, auditor, financial printers, proxy voting and class action claims processing service providers, pricing information vendors, consultants or agents operating under a contract with the investment adviser or its affiliates, co-litigants (such as in connection with a bankruptcy proceeding related to a fund holding) and certain other third parties described below, each of which requires portfolio holdings information for legitimate business and fund oversight purposes, may receive fund portfolio holdings information earlier. See the "General information" section in this statement of additional information for further information about the Series' custodian, outside counsel and auditor.

Each fund's portfolio holdings, dated as of the end of each calendar month, are made available to insurance companies that use the funds as underlying investments in their variable annuity contracts and variable life insurance policies. Monthly holdings are made available to help the insurance companies evaluate the funds for inclusion in the contracts and life insurance policies they offer and to evaluate and manage the insurance guarantees offered under their insurance contracts. Monthly holdings may be provided to insurance companies no earlier than the 10th day after the end of the calendar month. In practice, monthly holdings are provided within 30 days after the end of the calendar month. Monthly holdings may also be provided to the sub-adviser of the American Funds Insurance Series Managed Risk Funds. Holdings may also be disclosed more frequently to certain statistical and data collection agencies including Morningstar, Lipper, Inc., Value Line, Vickers Stock Research, Bloomberg and Thomson Financial Research. Information on certain portfolio characteristics of the funds are also provided to the insurance companies and the sub-adviser of the American Funds

Insurance Series Managed Risk Funds each business day. Intermediaries receiving the information are required to keep it confidential and use it only for the purposes described above.

Affiliated persons of the Series, including officers of the Series and employees of the investment adviser and its affiliates, who receive portfolio holdings information are subject to restrictions and limitations on the use and handling of such information pursuant to applicable codes of ethics, including requirements not to trade in securities based on confidential and proprietary investment information, to maintain the confidentiality of such information, and to pre-clear securities trades and report securities transactions activity, as applicable. For more information on these restrictions and limitations, please see the "Code of ethics" section in this statement of additional information and the Code of Ethics. Third-party service providers of the Series and other entities, as described in this statement of additional information, receiving such information are subject to confidentiality obligations and obligations that would prohibit them from trading in securities based on such information. When portfolio holdings information is disclosed other than through the Capital Group website to persons not affiliated with the Series, such persons will be bound by agreements (including confidentiality agreements) or fiduciary or other obligations that restrict and limit their use of the information to legitimate business uses only. None of the Series, its investment adviser or any of their affiliates receives compensation or other consideration in connection with the disclosure of information about portfolio securities.

Subject to board policies, the authority to disclose a fund's portfolio holdings, and to establish policies with respect to such disclosure, resides with the appropriate investment-related committees of the Series' investment adviser. In exercising their authority, the committees determine whether disclosure of information about the funds' portfolio securities is appropriate and in the best interest of fund shareholders. The investment adviser has implemented policies and procedures to address conflicts of interest that may arise from the disclosure of fund holdings. For example, the investment adviser's code of ethics specifically requires, among other things, the safeguarding of information about fund holdings and contains prohibitions designed to prevent the personal use of confidential, proprietary investment information in a way that would conflict with fund transactions. In addition, the investment adviser believes that its current policy of not selling portfolio holdings information and not disclosing such information to unaffiliated third parties until such holdings have been made public on the Capital Group website (other than to certain Series service providers and other third parties for legitimate business and fund oversight purposes) helps reduce potential conflicts of interest between fund shareholders and the investment adviser and its affiliates.

The Series' investment adviser and its affiliates provide investment advice to individuals and financial intermediaries that have investment objectives that may be substantially similar to those of the funds. These clients also may have portfolios consisting of holdings substantially similar to those of the funds and generally have access to current portfolio holdings information for their accounts. These clients do not owe the Series' investment adviser or the funds a duty of confidentiality with respect to disclosure of their portfolio holdings.

**Price of shares**

Shares are purchased at the offering price or sold at the net asset value price next determined after the purchase or sell order is received and accepted by the Series or its designee. Orders received by the Series or authorized designee after the time of the determination of the net asset value will be entered at the next calculated offering price.

The price you pay for shares, the offering price, is based on the net asset value per share. Net asset value is computed by adding the value of a fund's investments, cash or other assets, subtracting the fund's liabilities, and dividing the result by the number of shares that are outstanding. Realized investment income and gain is included in the fund's net asset value until the ex-dividend date, when the declared dividend amount is treated as a fund liability. The net asset value is calculated once daily as of the close of regular trading on the New York Stock Exchange, normally 4 p.m. New York time, each day the New York Stock Exchange is open. If the New York Stock Exchange makes a scheduled (e.g., the day after Thanksgiving) or an unscheduled close prior to 4 p.m. New York time, the net asset value of the fund will be determined at approximately the time the New York Stock Exchange closes on that day. If on such a day market quotations and prices from third-party pricing services are not based as of the time of the early close of the New York Stock Exchange but are as of a later time (up to approximately 4 p.m. New York time), for example because the market remains open after the close of the New York Stock Exchange, those later market quotations and prices will be used in determining the fund's net asset value.

Orders in good order received after the New York Stock Exchange closes (scheduled or unscheduled) will be processed at the net asset value (plus any applicable sales charge) calculated on the following business day. The New York Stock Exchange is currently closed on weekends and on the following holidays: New Year's Day; Martin Luther King Jr. Day; Presidents' Day; Good Friday; Memorial Day; Juneteenth National Independence Day; Independence Day; Labor Day; Thanksgiving Day; and Christmas Day. Each share class of the fund has a separately calculated net asset value (and share price). The fund's investment adviser delivers the net asset value every day it is calculated to each insurance company that offers such fund as an underlying investment to its variable contracts by, for example, email, direct electronic transmission or facsimile or through the systems of the National Securities Clearing Corporation.

All portfolio securities of funds managed by Capital Research and Management Company (other than American Funds U.S. Government Money Market Fund) are valued, and the net asset values per share for each share class are determined, as indicated below. The fund follows standard industry practice by typically reflecting changes in its holdings of portfolio securities on the first business day following a portfolio trade.

Equity securities, including depositary receipts, exchange-traded funds, and certain convertible preferred stocks that trade on an exchange or market, are generally valued at the official closing price of, or the last reported sale price on, the exchange or market on which such securities are traded, as of the close of business on the day the securities are being valued or, lacking any sales, at the last available bid price. Prices for each security are taken from the principal exchange or market on which the security trades.

Fixed income securities, including short-term securities, are generally valued at evaluated prices obtained from third-party pricing vendors. Vendors value such securities based on one or more inputs that may include, among other things, benchmark yields, transactions, bids, offers, quotations from dealers and trading systems, new issues, underlying equity of the issuer, interest rate volatilities, spreads and other relationships observed in the markets among comparable securities and proprietary pricing models such as yield measures calculated using factors such as cash flows, prepayment information, default rates, delinquency and loss assumptions, financial or collateral

------

characteristics or performance, credit enhancements, liquidation value calculations, specific deal information and other reference data.

Forward currency contracts are valued based on the spot and forward exchange rates obtained from a third-party pricing vendor.

Futures contracts are generally valued at the official settlement price of, or the last reported sale price on, the principal exchange or market on which such instruments are traded, as of the close of business on the day the contracts are being valued or, lacking any sales, at the last available bid price.

Swaps, including interest rate swaps, total return swaps and positions in credit default swap indices, are generally valued using evaluated prices obtained from third-party pricing vendors who calculate these values based on market inputs that may include yields of the indices referenced in the instrument and the relevant curve, dealer quotes, default probabilities and recovery rates, other reference data, and terms of the contract.

Options are valued using market quotations or valuations provided by one or more pricing vendors. Similar to futures, options may also be valued at the official settlement price if listed on an exchange.

Securities and other assets for which representative market quotations are not readily available or are considered unreliable by the investment adviser are valued at fair value as determined in good faith under fair value guidelines adopted by the investment adviser and approved by the Series' board. Subject to board oversight, the Series' board has designated the fund's investment adviser to make fair valuation determinations, which are directed by a valuation committee established by the fund's investment adviser. The board receives regular reports describing fair-valued securities and the valuation methods used.

As a general principle, these guidelines consider relevant company, market and other data and considerations to determine the price that the fund might reasonably expect to receive if such fair valued securities were sold in an orderly transaction. Fair valuations may differ materially from valuations that would have been used had greater market activity occurred. The investment adviser's valuation committee considers relevant indications of value that are reasonably and timely available to it in determining the fair value to be assigned to a particular security, such as the type and cost of the security, restrictions on resale of the security, relevant financial or business developments of the issuer, actively traded similar or related securities and transactions, dealer or broker quotes, conversion or exchange rights on the security, related corporate actions, significant events occurring after the close of trading in the security and changes in overall market conditions. The valuation committee employs additional fair value procedures to address issues related to equity securities that trade principally in markets outside the United States. Such securities may trade in markets that open and close at different times, reflecting time zone differences. If significant events occur after the close of a market (and before the fund's net asset values are next determined) which affect the value of equity securities held in the fund's portfolio, appropriate adjustments from closing market prices may be made to reflect these events. Events of this type could include, for example, earthquakes and other natural disasters or significant price changes in other markets (e.g., U.S. stock markets).

Assets and liabilities, including investment securities, denominated in currencies other than U.S. dollars are translated into U.S. dollars, prior to the next determination of the net asset value of the fund's shares, at the exchange rates obtained from a third-party pricing vendor.

Each class of shares represents interests in the same portfolio of investments and is identical in all respects to each other class, except for differences relating to distribution, service and other charges and expenses, certain voting rights, differences relating to eligible investors, the designation of each class of shares, conversion features and exchange privileges. Expenses attributable to the fund, but

American Funds Insurance Series — Page 92

------

not to a particular class of shares, are borne by each class pro rata based on the relative aggregate net assets of the classes. Expenses directly attributable to a class of shares are borne by that class of shares. Liabilities attributable to particular share classes, such as liabilities for repurchases of fund shares, are deducted from total assets attributable to such share classes.

Net assets so obtained for each share class are then divided by the total number of shares outstanding of that share class, and the result, rounded to the nearest cent, is the net asset value per share for that class.

**Taxes and distributions**

**Taxation as a regulated investment company** — The Series intends to qualify each year as a "regulated investment company" under Subchapter M of the Internal Revenue Code ("Code") so that it will not be liable for federal tax on income and capital gains distributed to shareholders. In order to qualify as a regulated investment company, and avoid being subject to federal income taxes, the Series intends to distribute substantially all of its net investment income and realized net capital gains on a fiscal year basis, and intends to comply with other tests applicable to regulated investment companies under Subchapter M.

The Code includes savings provisions allowing the Series to cure inadvertent failures of certain qualification tests required under Subchapter M. However, should the Series fail to qualify under Subchapter M, the Series would be subject to federal, and possibly state, corporate taxes on its taxable income and gains.

The Series is subject to a set of asset diversification requirements applicable to insurance company separate accounts and their underlying funding vehicles. To satisfy these diversification requirements, as of the end of each calendar quarter or within 30 days thereafter, the Series must (*a*) be qualified as a "regulated investment company"; and (*b*) have either (*i*) no more than 55% of the total value of its assets in cash and cash equivalents, government securities and securities of other regulated investment companies; or (*ii*) no more than 55% of its total assets represented by any one investment, no more than 70% by any two investments, no more than 80% by any three investments, and no more than 90% by any four investments. For this purpose all securities of the same issuer are considered a single investment, and each agency or instrumentality of the U.S. government is treated as a separate issuer of securities. The Series intends to comply with these regulations. If the Series should fail to comply with these regulations, Contracts invested in the Series will not be treated as annuity, endowment or life insurance contracts under the Code.

The Series may declare a capital gain distribution consisting of the excess of net realized long-term capital gains over net realized short-term capital losses. Net capital gains for a fiscal year are computed by taking into account any capital loss carryforward of the Series.

Certain distributions reported by the Series as Section 163(j) interest dividends may be treated as interest income by shareholders for purposes of the tax rules applicable to interest expense limitations under Section 163(j) of the Code. Such treatment by the shareholder is generally subject to holding period requirements and other potential limitations, although the holding period requirements are generally not applicable to dividends declared by money market funds and certain other funds that declare dividends daily and pay such dividends on a monthly or more frequent basis. The amount that the Series is eligible to report as a Section 163(j) dividend for a tax year is generally limited to the excess of the Series' business interest income over the sum of the Series' (i) business interest expense and (ii) other deductions properly allocable to the Series' business interest income.

**Tax consequences of investing in non-U.S. securities —** Dividend and interest income received by the Series from sources outside the United States may be subject to withholding and other taxes imposed by such foreign jurisdictions. Tax conventions between certain countries and the United States, however, may reduce or eliminate these foreign taxes. Some foreign countries impose taxes on capital gains with respect to investments by foreign investors.

Foreign currency gains and losses, including the portion of gain or loss on the sale of debt securities attributable to fluctuations in foreign exchange rates, are generally taxable as ordinary income or loss. These gains or losses may increase or decrease the amount of dividends payable by the Series to shareholders. The Series may elect to treat gain and loss on certain foreign currency contracts as capital gain and loss instead of ordinary income or loss.

American Funds Insurance Series — Page 94

------

If the fund invests in stock of certain passive foreign investment companies (PFICs), the fund intends to mark-to-market these securities and recognize any gains at the end of its fiscal and excise tax years. Deductions for losses are allowable only to the extent of any previously recognized gains. Both gains and losses will be treated as ordinary income or loss, and the fund is required to distribute any resulting income. If the fund is unable to identify an investment as a PFIC security and thus does not make a timely mark-to-market election, the fund may be subject to adverse tax consequences.

**Tax consequences of investing in derivatives** — The Series may enter into transactions involving derivatives, such as futures, swaps, options and forward contracts. Special tax rules may apply to these types of transactions that could defer losses to the Series, accelerate the Series' income, alter the holding period of certain securities or change the classification of capital gains. These tax rules may therefore impact the amount, timing and character of fund distributions.

**Discount —** Certain bonds acquired by the fund, such as zero coupon bonds, may be treated as bonds that were originally issued at a discount. Original issue discount represents interest for federal income tax purposes and is generally defined as the difference between the price at which a bond was issued (or the price at which it was deemed issued for federal income tax purposes) and its stated redemption price at maturity. Original issue discount is treated for federal income tax purposes as tax exempt income earned by a fund over the term of the bond, and therefore is subject to the distribution requirements of the Code. The annual amount of income earned on such a bond by a fund generally is determined on the basis of a constant yield to maturity which takes into account the semiannual compounding of accrued interest (including original issue discount). Certain bonds acquired by the fund may also provide for contingent interest and/or principal. In such a case, rules similar to those for original issue discount bonds would require the accrual of income based on an assumed yield that may exceed the actual interest payments on the bond.

Some of the bonds may be acquired by a fund on the secondary market at a discount which exceeds the original issue discount, if any, on such bonds. This additional discount constitutes market discount for federal income tax purposes. Any gain recognized on the disposition of any bond having market discount generally will be treated as taxable ordinary income to the extent it does not exceed the accrued market discount on such bond (unless a fund elects to include market discount in income in the taxable years to which it is attributable). Realized accrued market discount on obligations that pay tax-exempt interest is nonetheless taxable. Generally, market discount accrues on a daily basis for each day the bond is held by a fund at a constant rate over the time remaining to the bond's maturity. In the case of any debt instrument having a fixed maturity date of not more than one year from date of issue, the gain realized on disposition will be treated as short-term capital gain. Some of the bonds acquired by a fund with a fixed maturity date of one year or less from the date of their issuance may be treated as having original issue discount or, in certain cases, "acquisition discount" (generally, the excess of a bond's stated redemption price at maturity over its acquisition price). A fund will be required to include any such original issue discount or acquisition discount in taxable ordinary income. The rate at which such acquisition discount and market discount accrues, and is thus included in a fund's investment company taxable income, will depend upon which of the permitted accrual methods the fund elects.

**General information**

**Custodian of assets —** Securities and cash owned by all funds, including proceeds from the sale of shares of the funds and of securities in the funds' portfolios, are held by State Street Bank and Trust Company, One Lincoln Street, Boston, MA 02111, as custodian. Non-U.S. securities may be held by the custodian in non-U.S. banks or securities depositories or foreign branches of U.S. banks.

**Transfer agent services —** American Funds Service Company, a wholly owned subsidiary of the investment adviser, maintains the records of each insurance company's separate account, processes purchases and redemptions of the funds' shares, acts as dividend and capital gain distribution disbursing agent, and performs other related shareholder service functions. The principal office of American Funds Service Company is located at 6455 Irvine Center Drive, Irvine, CA 92618. Transfer agent fees are paid according to a fee schedule, based on the number of accounts serviced, contained in a Shareholder Services Agreement between the Series and American Funds Service Company. American Funds Service Company was paid a fee of $20,000 for Class 1 shares, less than $1,000 for Class 1A shares, $13,000 for Class 2 shares, less than $1,000 for Class 3 shares and $4,000 for Class 4 shares for the 2025 fiscal year.

**Independent registered public accounting firm —** During the fiscal year ended December 31, 2025, PricewaterhouseCoopers LLP ("PwC"), 601 South Figueroa Street, Los Angeles, CA 90017, served as the Series' independent registered public accounting firm, providing audit services, preparation of tax returns and review of certain documents to be filed with the SEC. The financial statements and financial highlights of the Series included in this statement of additional information that are from the Series' Form N-CSR for the most recent fiscal year have been audited by PwC, an independent registered public accounting firm, as stated in their report appearing herein. Such financial statements and financial highlights are included in reliance upon the report of such firm given upon their authority as experts in accounting and auditing. The selection of the Series' independent registered public accounting firm is reviewed and determined annually by the board of trustees.

On December 10, 2025, PwC was replaced by Deloitte & Touch LLP ("D&T") which was appointed as the Series' independent registered public accounting firm for the fiscal year December 31, 2026 audits. The change in the Series' independent registered public accounting firm was approved by the Series' board of trustees, including a majority of the independent trustees, upon recommendation of the audit committee, as part of a broader effort to update board oversight and fund operations. At no point during the Series' fiscal years ended December 31, 2024 and December 31, 2025 and the subsequent interim period through February 11, 2026, were there any disagreements between management and PwC on any matter of accounting principles or practices, financial statement disclosure or auditing scope or procedure.

**Independent legal counsel —** Morgan, Lewis & Bockius LLP, One Federal Street, Boston, MA 02110-1726, serves as independent legal counsel ("counsel") for the Series and for trustees who are not interested persons (as defined by the 1940 Act) of the Series. A determination with respect to the independence of the Series' counsel will be made at least annually by the independent trustees of the Series, as prescribed by applicable 1940 Act rules.

**Prospectuses and reports to shareholders —** The Series' fiscal year ends on December 31. Contract owners are provided updated prospectuses or summary prospectuses by their insurance provider annually and at least semiannually with reports showing the funds' expenses, key statistics, holdings information and investment results (annual report only). The Series' annual financial statements are audited by the independent registered public accounting firm of PwC. The Series' annual financial statements for the fiscal year ended December 31, 2025 were audited by the Series' then-independent registered public accounting firm, PwC. As noted above, D&T will serve as the Series' auditor beginning with the fiscal year ending December 31, 2026.

**Code of ethics —** The Series, Capital Research and Management Company and its affiliated companies have adopted codes of ethics that allow for personal investments, including securities in which the funds of the Series may invest from time to time. These codes include a ban on acquisitions of securities pursuant to an initial public offering; restrictions on acquisitions of private placement securities; pre-clearance and reporting requirements; review of duplicate confirmation statements; annual recertification of compliance with codes of ethics; blackout periods on personal investing for certain investment personnel; a ban on short-term trading profits for investment personnel; limitations on service as a director of publicly traded companies; disclosure of personal securities transactions; and policies regarding political contributions.

**Shareholder and trustee responsibility —** Under the laws of certain states, including Massachusetts, where the Series was organized, and California, where the Series' principal office is located, shareholders of a Massachusetts business trust may, under certain circumstances, be held personally liable as partners for the obligations of the Series. However, the risk of a shareholder incurring any financial loss on account of shareholder liability is limited to circumstances in which the Series itself would be unable to meet its obligations. The declaration of trust contains an express disclaimer of shareholder liability for acts or obligations of the Series and provides that notice of the disclaimer may be given in each agreement, obligation, or instrument which is entered into or executed by the Series or trustees. The declaration of trust provides for indemnification out of Series property of any shareholder personally liable for the obligations of the Series and also provides for the Series to reimburse such shareholder for all legal and other expenses reasonably incurred in connection with any such claim or liability.

Under the declaration of trust, the trustees or officers are not liable for actions or failure to act; however, they are not protected from liability by reason of their willful misfeasance, bad faith, gross negligence, or reckless disregard of the duties involved in the conduct of their office. The Series will provide indemnification to its trustees and officers as authorized by its by-laws and by the 1940 Act and the rules and regulations thereunder.

**Registration statement —** A registration statement has been filed with the Securities and Exchange Commission under the Securities Act of 1933 and the 1940 Act with respect to the Series. The prospectus and this statement of additional information do not contain all information set forth in the registration statement, its amendments and exhibits, to which reference is made for further information concerning the Series. Statements contained in the prospectus and this statement of additional information as to the content of the contracts issued through the separate accounts and other legal instruments are summaries. For a complete statement of the terms thereof, reference is made to the registration statements of the separate accounts and contracts as filed with the Securities and Exchange Commission.

**Authorized shares —** The Series was organized as a Massachusetts business trust which permits each fund of the Series to issue an unlimited number of shares of beneficial interest of one or more classes.

**Redemption of shares —** While payment of redemptions normally will be in cash, the Series' declaration of trust permits payment of the redemption price wholly or partly with portfolio securities or other fund assets under conditions and circumstances determined by the Series' board of trustees. For example, redemptions could be made in this manner if the board determined that making payments wholly in cash over a particular period would be unfair and/or harmful to other Series shareholders.

**Voting rights —** Shareholders have one vote per share owned. In accordance with current laws, it is anticipated that an insurance company issuing a variable contract that participates in a fund will request voting instructions from variable contract owners and will vote shares or other voting interests in the separate account in accordance with voting instructions received, and will vote shares or other

American Funds Insurance Series — Page 97

voting interests not received in proportion to the voting instructions received by all separate accounts. In addition, fund shares held directly by an insurance company, if any, will be voted in proportion to the voting instructions received by all separate accounts. As a result of proportional voting, the vote of a small number of contract holders could determine the outcome of a shareholder vote.

**Credit facility —** SMALLCAP World Fund, New World Fund and American High-Income Trust, together with other U.S. registered investment funds managed by Capital Research and Management Company, have entered into a committed line of credit facility pursuant to which the funds may borrow up to $1.5 billion as a source of temporary liquidity on a first-come, first-served basis. Under the credit facility, loans are generally unsecured; however, a borrowing fund must collateralize any borrowings under the facility on an equivalent basis if it has certain other collateralized borrowings.

**Financial statements —** The fund's financial statements, including the investment portfolio and the report of the fund's independent registered public accounting firm contained in the fund's Form N-CSR, are incorporated into the statement of additional information by reference to the fund's Form N-CSR.

**Appendix**

The following descriptions of debt security ratings are based on information provided by Moody's Investors Service, S&P Global Ratings and Fitch Ratings, Inc.

**Description of bond ratings**

**Moody's<br> Long-term rating scale**

**Aaa**<br> Obligations rated Aaa are judged to be of the highest quality, subject to the lowest level of credit risk.

**Aa**<br> Obligations rated Aa are judged to be of high quality and are subject to very low credit risk.

**A**<br> Obligations rated A are considered upper-medium grade and are subject to low credit risk.

**Baa**<br> Obligations rated Baa are judged to be medium-grade and subject to moderate credit risk and as such may possess certain speculative characteristics.

**Ba**<br> Obligations rated Ba are judged to be speculative and are subject to substantial credit risk.

**B**<br> Obligations rated B are considered speculative and are subject to high credit risk.

**Caa**<br> Obligations rated Caa are judged to be speculative and of poor standing and are subject to very high credit risk.

**Ca**<br> Obligations rated Ca are highly speculative and are likely in, or very near, default, with some prospect of recovery of principal and interest.

**C**<br> Obligations rated C are the lowest rated and are typically in default, with little prospect for recovery of principal or interest.

**Note:** Moody's appends numerical modifiers 1, 2, and 3 to each generic rating classification from Aa through Caa. The modifier 1 indicates that the obligation ranks in the higher end of its generic rating category; the modifier 2 indicates a mid-range ranking; and the modifier 3 indicates a ranking in the lower end of that generic rating category. Additionally, a "(hyb)" indicator is appended to all ratings of hybrid securities issued by banks, insurers, finance companies and securities firms.

American Funds Insurance Series — Page 99

------

**S&P Global Ratings<br> Long-term issue credit ratings**

**AAA**<br> An obligation rated AAA has the highest rating assigned by S&P Global Ratings. The obligor's capacity to meet its financial commitments on the obligation is extremely strong.

**AA**<br> An obligation rated AA differs from the highest-rated obligations only to a small degree. The obligor's capacity to meet its financial commitments on the obligation is very strong.

**A**<br> An obligation rated A is somewhat more susceptible to the adverse effects of changes in circumstances and economic conditions than obligations in higher-rated categories. However, the obligor's capacity to meet its financial commitments on the obligation is still strong.

**BBB**<br> An obligation rated BBB exhibits adequate protection parameters. However, adverse economic conditions or changing circumstances are more likely to weaken the obligor's capacity to meet its financial commitments on the obligation.

**BB, B, CCC, CC, and C**

Obligations rated BB, B, CCC, CC, and C are regarded as having significant speculative characteristics. BB indicates the least degree of speculation and C the highest. While such obligations will likely have some quality and protective characteristics, these may be outweighed by large uncertainties or major exposures to adverse conditions.

**BB**<br> An obligation rated BB is less vulnerable to nonpayment than other speculative issues. However, it faces major ongoing uncertainties or exposure to adverse business, financial, or economic conditions which could lead to the obligor's inadequate capacity to meet its financial commitments on the obligation.

**B**<br> An obligation rated B is more vulnerable to nonpayment than obligations rated BB, but the obligor currently has the capacity to meet its financial commitments on the obligation. Adverse business, financial, or economic conditions will likely impair the obligor's capacity or willingness to meet its financial commitments on the obligation.

**CCC**<br> An obligation rated CCC is currently vulnerable to nonpayment and is dependent upon favorable business, financial, and economic conditions for the obligor to meet its financial commitments on the obligation. In the event of adverse business, financial, or economic conditions, the obligor is not likely to have the capacity to meet its financial commitments on the obligation.

**CC**<br> An obligation rated CC is currently highly vulnerable to nonpayment. The CC rating is used when a default has not occurred, but S&P Global Ratings expects default to be a virtual certainty, regardless of the anticipated time to default.

American Funds Insurance Series — Page 100

------

**C**<br> An obligation rated C is currently highly vulnerable to nonpayment, and the obligation is expected to have lower relative seniority or lower ultimate recovery compared with obligations that are rated higher.

**D**<br> An obligation rated D is in default or in breach of an imputed promise. For non-hybrid capital instruments, the D rating category is used when payments on an obligation are not made on the date due, unless S&P Global Ratings believes that such payments will be made within the next five business days in the absence of a stated grace period or within the earlier of the stated grace period or the next 30 calendar days. The D rating also will be used upon the filing of a bankruptcy petition or the taking of similar action and where default on an obligation is a virtual certainty, for example due to automatic stay provisions. A rating on an obligation is lowered to D if it is subject to a distressed debt restructuring.

#### Plus (+) or minus (–)
The ratings from AA to CCC may be modified by the addition of a plus or minus sign to show relative standing within the major rating categories.

#### NR
Indicates that a rating has not been assigned or is no longer assigned.

American Funds Insurance Series — Page 101

**Fitch Ratings, Inc.<br> Long-term credit ratings**

**AAA**<br> Highest credit quality. AAA ratings denote the lowest expectation of default risk. They are assigned only in case of exceptionally strong capacity for payment of financial commitments. This capacity is highly unlikely to be adversely affected by foreseeable events.

**AA**<br> Very high credit quality. AA ratings denote expectations of very low default risk. They indicate very strong capacity for payment of financial commitments. This capacity is not significantly vulnerable to foreseeable events.

**A**<br> High credit quality. A ratings denote expectations of low default risk. The capacity for payment of financial commitments is considered strong. This capacity may, nevertheless, be more vulnerable to changes in circumstances or in economic conditions than is the case for higher ratings.

**BBB**<br> Good credit quality. BBB ratings indicate that expectations of default risk are low. The capacity for payment of financial commitments is considered adequate but adverse changes in circumstances and economic conditions are more likely to impair this capacity.

**BB**<br> Speculative. BB ratings indicate an elevated vulnerability to default risk, particularly in the event of adverse changes in business or economic conditions over time; however, business or financial flexibility exists which supports the servicing of financial commitments.

**B**<br> Highly speculative. B ratings indicate that material default risk is present, but a limited margin of safety remains. Financial commitments are currently being met; however, capacity for continued payment is vulnerable to deterioration in the business and economic environment.

**CCC**<br> Substantial credit risk. Default is a real possibility.

**CC**<br> Very high levels of credit risk. Default of some kind appears probable.

**C**<br> Exceptionally high levels of credit risk. Default is imminent or inevitable, or the issuer is in standstill. Conditions that are indicative of a C category rating for an issuer include:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;·The issuer has entered into a grace or cure period following nonpayment of a material financial obligation;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;·The issuer has entered into a temporary negotiated waiver or standstill agreement following a payment default on a material financial obligation; or

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;·Fitch Ratings otherwise believes a condition of RD or D to be imminent or inevitable, including through the formal announcement of a distressed debt exchange.

American Funds Insurance Series — Page 102

------

**RD**<br> Restricted default. RD ratings indicate an issuer that in Fitch Ratings' opinion has experienced an uncured payment default on a bond, loan or other material financial obligation but which has not entered into bankruptcy filings, administration, receivership, liquidation or other formal winding up procedure, and which has not otherwise ceased operating. This would include:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;·The selective payment default on a specific class or currency of debt;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;·The uncured expiry of any applicable grace period, cure period or default forbearance period following a payment default on a bank loan, capital markets security or other material financial obligation;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;·The extension of multiple waivers or forbearance periods upon a payment default on one or more material financial obligations, either in series or in parallel; or

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;·Execution of a distressed debt exchange on one or more material financial obligations.

**D**<br> Default. D ratings indicate an issuer that in Fitch Ratings' opinion has entered into bankruptcy filings, administration, receivership, liquidation or other formal winding up procedure, or which has otherwise ceased business.

Default ratings are not assigned prospectively to entities or their obligations; within this context, nonpayment on an instrument that contains a deferral feature or grace period will generally not be considered a default until after the expiration of the deferral or grace period, unless a default is otherwise driven by bankruptcy or other similar circumstance, or by a distressed debt exchange.

Imminent default typically refers to the occasion where a payment default has been intimated by the issuer, and is all but inevitable. This may, for example, be where an issuer has missed a scheduled payment, but (as is typical) has a grace period during which it may cure the payment default. Another alternative would be where an issuer has formally announced a distressed debt exchange, but the date of the exchange still lies several days or weeks in the immediate future.

In all cases, the assignment of a default rating reflects the agency's opinion as to the most appropriate rating category consistent with the rest of its universe of ratings, and may differ from the definition of default under the terms of an issuer's financial obligations or local commercial practice.

**Note:** The modifiers "+" or "–" may be appended to a rating to denote relative status within major rating categories. Such suffixes are not added to the AAA long-term rating category, or to categories below B.

**Description of commercial paper ratings**

**Moody's**

**Global short-term rating scale**

#### P-1
Issuers (or supporting institutions) rated Prime-1 have a superior ability to repay short-term debt obligations.

**P-2**

Issuers (or supporting institutions) rated Prime-2 have a strong ability to repay short-term debt obligations.

#### P-3
Issuers (or supporting institutions) rated Prime-3 have an acceptable ability to repay short-term obligations.

**NP**

Issuers (or supporting institutions) rated Not Prime do not fall within any of the Prime rating categories.

#### S&P Global Ratings
**Commercial paper ratings (highest three ratings)**

**A-1**

A short-term obligation rated A-1 is rated in the highest category by S&P Global Ratings. The obligor's capacity to meet its financial commitments on the obligation is strong. Within this category, certain obligations are designated with a plus sign (+). This indicates that the obligor's capacity to meet its financial commitments on these obligations is extremely strong.

**A-2**

A short-term obligation rated A-2 is somewhat more susceptible to the adverse effects of changes in circumstances and economic conditions than obligations in higher rating categories. However, the obligor's capacity to meet its financial commitments on the obligation is satisfactory.

**A-3**

A short-term obligation rated A-3 exhibits adequate protection parameters. However, adverse economic conditions or changing circumstances are more likely to weaken an obligor's capacity to meet its financial commitments on the obligation.

 **Managed Risk EUPAC Fund** 

**Investment objective** The fund's investment objective is to provide you with long-term growth of capital while seeking to manage volatility and provide downside protection.

**Fees and expenses of the fund** This table describes the fees and expenses that you may pay if you buy, hold and sell an interest in Class P1 shares of the fund. **You may pay other fees, such as insurance contract fees and expenses, which are not reflected in the tables and examples below.** If insurance contract fees and expenses were reflected, expenses shown would be higher.

| **Annual fund operating expenses (expenses that you pay each year as a percentage of the net asset value of your investment)** | Class P1 |
| Management fees | 0.10% |
| Distribution fees |  |
| Other expenses | 0.31 |
| Acquired (underlying) fund fees and expenses<sup>1</sup> | 0.43 |
| Total annual fund operating expenses | 0.84 |
| Expense reimbursement<sup>2</sup> | 0.03 |
| Total annual fund operating expenses after expense reimbursement | 0.81 |

<sup>1</sup> Restated to reflect current fees.

<sup>2</sup>The investment adviser is currently reimbursing a portion of the other expenses. This reimbursement will be in effect through at least May 1, 2027. The adviser may elect at its discretion to extend, modify or terminate the reimbursement at that time.

**Example** This example is intended to help you compare the cost of investing in Class P1 shares of the fund with the cost of investing in other mutual funds.

The example assumes that you invest $10,000 in the fund for the time periods indicated and then redeem or hold all of your shares at the end of those periods. The example also assumes that your investment has a 5% return each year and that the fund's operating expenses remain the same. The example does not reflect insurance contract expenses. If insurance contract expenses were reflected, expenses shown would be higher. The example reflects the expense reimbursement described above through the expiration date of such reimbursement and total annual fund operating expenses thereafter. No sales charge (load) or other fees are charged by the fund upon redemption, so you would incur these hypothetical costs whether or not you were to redeem your shares at the end of the given period. Although your actual costs may be higher or lower, based on these assumptions your costs would be:

|:---|:---|:---|:---|:---|
|  | 1 year | 3 years | 5 years | 10 years |
| Class P1 | $83 | $265 | $463 | $1034 |

---

**Portfolio turnover** The fund pays transaction costs, such as commissions, when it buys and sells securities and other instruments (or "turns over" its portfolio). A higher portfolio turnover rate may indicate higher transaction costs. These costs, which are not reflected in annual fund operating expenses or in the example, affect the fund's investment results. During the most recent fiscal year, the fund's portfolio turnover rate was 17% of the average value of its portfolio.

**Principal investment strategies** The fund pursues its investment objective by investing in shares of two underlying funds, the American Funds Insurance Series – EUPAC Fund (the "EUPAC Fund") and the American Funds Insurance Series – The Bond Fund of America ("The Bond Fund of America") – while seeking to manage portfolio volatility and provide downside protection primarily through the use of exchange-traded options and futures contracts.

The fund normally seeks to invest 85% of its assets in the EUPAC Fund, the investment objective of which is to provide long-term growth of capital. The EUPAC Fund invests primarily in common stocks in Europe and the Pacific Basin that the investment adviser believes have the potential for growth. Growth stocks are stocks that the investment adviser believes have the potential for above average capital appreciation. The fund invests the remainder of its assets in The Bond Fund of America and in cash, financial futures and options as part of the managed risk strategy. The Bond Fund of America's investment objective is to provide as high a level of current income as is consistent with the preservation of capital. The Bond Fund of America seeks to maximize your level of current income and preserve your capital by investing primarily in bonds. Normally, The Bond Fund of America invests at least 80% of its assets in bonds and other debt securities, which may be represented by derivatives. The Bond Fund of America invests at least 60% of its assets in debt securities (excluding derivatives) rated A3 or better or A- or better by Nationally Recognized Statistical Ratings Organizations designated by the fund's investment adviser, or in debt securities that are unrated but determined to be of equivalent quality by the fund's investment adviser and in U.S. government securities, money market instruments, cash or cash equivalents.

The fund's investment in The Bond Fund of America seeks to provide a level of diversification across asset classes. Because different asset classes often react differently to changes in market conditions, such diversification seeks to manage the fund's risk to market changes, including stock market declines. Additionally, the fund employs a risk-management overlay referred to in this prospectus as the managed risk strategy. The managed risk strategy consists of using hedge instruments — primarily exchange-traded futures contracts and/or exchange-traded put options — to attempt to stabilize the volatility of the fund around a target volatility level and to seek to reduce the downside exposure of the fund. The fund employs a subadviser to select individual put options and futures contracts on equity indexes of U.S. markets and markets outside the United States that the subadviser believes are correlated to the underlying fund's equity exposure. These instruments are selected based on the subadviser's analysis of the relation of various equity indexes to the underlying fund's portfolio. In addition, the subadviser will monitor liquidity levels of relevant options and futures contracts and transparency provided by exchanges as the counterparties in hedging transactions. The target volatility level will be set from time to time by the investment adviser and the subadviser and may be adjusted if deemed advisable in the judgment of the investment adviser and the subadviser. The

1&nbsp;&nbsp;&nbsp;&nbsp; American Funds Insurance Series — Managed Risk Funds / Prospectus

------

subadviser may also seek to hedge the fund's currency risk related to its exposure to equity index options and futures denominated in currencies other than the U.S. dollar.

A futures contract on an index is an agreement pursuant to which two parties agree to take or make delivery of an amount of cash linked to the value of the index at the close of the last trading day of the contract. Though similar, an option on an index gives one party the contractual right (but not the obligation) to take or make delivery of an amount of cash linked to the value of the underlying index. Because such instruments derive their respective values from the price of an underlying index, both options and futures contracts are considered derivatives. A long position in an equity index put option and a short position in an equity index futures contract are both expected to gain in value when the underlying index declines, and lose value when the underlying index rises.

The subadviser regularly adjusts the level of exchange-traded options and futures contracts held by the fund to seek to manage the fund's overall net risk level. In situations of extreme market volatility, the subadviser will tend to use exchange-traded equity index options and/or futures more heavily, as such investments could significantly reduce the fund's net economic exposure to equity securities. Even in periods of low volatility in the equity markets, however, the subadviser will continue to employ exchange-traded equity index put options to seek to preserve gains after favorable market conditions and to reduce losses in adverse market conditions. During such periods of low equity market volatility, the subadviser may also continue to use exchange-traded equity index futures contracts for hedging purposes, though it need not necessarily do so. In certain market conditions, the fund may also purchase exchange-traded equity index call options, write or sell exchange-traded equity index put and call options and/or take net long positions in exchange-traded equity index futures contracts.

Prior to May 1, 2026, the fund was called Managed Risk International Fund.

**Principal risks This section describes the principal risks associated with investing in the fund. You may lose money by investing in the fund. The likelihood of loss may be greater if you invest for a shorter period of time. Investors in the fund should also understand that the fund's objective of protecting against downside losses may result in the fund not realizing the full gains of the underlying funds. In addition, the managed risk strategy may not effectively protect the fund from market declines.** 

*Fund structure* — The fund invests in underlying funds and incurs expenses related to those underlying funds. In addition, investors in the fund will incur fees to pay for certain expenses related to the operations of the fund. An investor holding the underlying funds directly would incur lower overall expenses but would not receive the benefit of the managed risk strategy. Additionally, in accordance with an exemption under the Investment Company Act of 1940, as amended, the investment adviser considers only proprietary funds when selecting underlying investment options and allocations. This means that the fund's investment adviser does not, nor does it expect to, consider any unaffiliated funds as underlying investment options for the fund. This strategy could raise certain conflicts of interest when determining the overall asset allocation of the fund or choosing underlying investments for the fund, including the selection of funds that result in greater compensation to the adviser or funds with relatively lower historical investment results. The investment adviser has policies and procedures designed to mitigate material conflicts of interest that may arise in connection with its management of the fund.

*Underlying fund risks* — Because the fund's investments consist of investments in underlying funds, the fund's risks are directly related to the risks of those underlying funds. For this reason, it is important to understand the risks associated with investing both in the fund and in each of the underlying funds.

*Investing in derivatives* — The use of derivatives involves a variety of risks, which may be different from, or greater than, the risks associated with investing in traditional securities, such as stocks and bonds. Changes in the value of a derivative may not correlate perfectly with, and may be more sensitive to market events than, the underlying asset, rate or index, and a derivative instrument may cause the fund or an underlying fund to lose significantly more than its initial investment. Derivatives may be difficult to value, difficult for the fund or an underlying fund to buy or sell at an opportune time or price and difficult, or even impossible, to terminate or otherwise offset. A fund's use of derivatives may result in losses to the fund, and investing in derivatives may reduce the fund's returns and increase the fund's price volatility. A fund's counterparty to a derivative transaction (including, if applicable, the fund's clearing broker, the derivatives exchange or the clearinghouse) may be unable or unwilling to honor its financial obligations in respect of the transaction. In certain cases, the fund or an underlying fund may be hindered or delayed in exercising remedies against or closing out derivative instruments with a counterparty, which may result in additional losses. Derivatives are also subject to operational risk (such as documentation issues, settlement issues and systems failures) and legal risk (such as insufficient documentation, insufficient capacity or authority of a counterparty, and issues with the legality or enforceability of a contract).

*Investing in options and futures contracts* — In addition to the risks generally associated with investing in derivative instruments, options and futures contracts are subject to the creditworthiness of the clearing organizations, exchanges and, in the case of futures, futures commission merchants with which the fund transacts. While both options and futures contracts are generally liquid instruments, under certain market conditions, options and futures may be deemed to be illiquid. For example, the fund may be temporarily prohibited from closing out its position in an options or futures contract if intraday price change limits or limits on trading volume imposed by the applicable exchange are triggered. If the fund is unable to close out a position on an options or futures contract, the fund would remain subject to the risk of adverse price movements until the fund is able to close out the position in question. The ability of the fund to successfully utilize options and futures contracts may depend in part upon the ability of the fund's investment adviser or subadviser to accurately forecast interest rates and other economic factors and to assess and predict the impact of such economic factors on the options and futures in which the fund invests. If the investment adviser or subadviser incorrectly forecasts economic developments or incorrectly predicts the impact of such developments on the options and futures in which it invests, the fund could suffer losses. Whereas the risk of loss on a put option purchased by the fund is limited to the initial cost of the option, the amount of a potential loss on a futures contract could greatly exceed the relatively small initial amount invested in entering the futures position.

*Hedging* — There may be imperfect or even negative correlation between the prices of the options and futures contracts in which the fund invests and the prices of the underlying securities or indexes which the fund seeks to hedge. For example, options and futures contracts may not provide an effective hedge because changes in options and futures contract prices may not track those of the underlying

American Funds Insurance Series — Managed Risk Funds / Prospectus&nbsp;&nbsp;&nbsp;&nbsp; 2

------

securities or indexes they are intended to hedge. In addition, there are significant differences between the securities market, on the one hand, and the options and futures markets, on the other, that could result in an imperfect correlation between the markets, causing a given hedge not to achieve its objectives. The degree of imperfection of correlation depends on circumstances such as variations in speculative market demand for options and futures, including technical influences in options and futures trading, and differences between the financial instruments being hedged and the instruments underlying the standard contracts available for trading. A decision as to whether, when and how to hedge involves the exercise of skill and judgment, and even a well-conceived hedge may be unsuccessful to some degree because of market behavior or unexpected interest rate trends. In addition, the fund's investment in exchange-traded options and futures and their resulting costs could limit the fund's gains in rising markets relative to those of the underlying funds, or to those of unhedged funds in general.

*Short positions* — The fund may suffer losses from short positions in futures contracts. Losses from short positions in futures contracts occur when the underlying index increases in value. As the underlying index increases in value, the holder of the short position in the corresponding futures contract is required to pay the difference in value of the futures contract resulting from the increase in the index on a daily basis. Losses from a short position in an index futures contract could potentially be very large if the value of the underlying index rises dramatically in a short period of time.

*Market conditions* — The prices of, and the income generated by, the securities held by an underlying fund may decline – sometimes rapidly or unpredictably – due to various factors, including events or conditions affecting the general economy or particular industries or companies; overall market changes; local, regional or global political, social or economic instability; governmental, governmental agency or central bank responses to economic conditions; levels of public debt and deficits; changes in inflation rates; and currency exchange rate, interest rate and commodity price fluctuations.

Economies and financial markets throughout the world are highly interconnected. Economic, financial or political events, trading and tariff arrangements, wars, terrorism, cybersecurity events, natural disasters, public health emergencies (such as the spread of infectious disease), bank failures and other circumstances in one country or region, including actions taken by governmental or quasi-governmental authorities in response to any of the foregoing, could have impacts on global economies or markets. As a result, whether or not an underlying fund invests in securities of issuers located in or with significant exposure to the countries affected, the value and liquidity of an underlying fund's investments may be negatively affected by developments in other countries and regions.

*Issuer risks* — The prices of, and the income generated by, securities held by an underlying fund may decline in response to various factors directly related to the issuers of such securities, including reduced demand for an issuer's goods or services, poor management performance, major litigation, investigations or other controversies related to the issuer, changes in the issuer's financial condition or credit rating, changes in government regulations affecting the issuer or its competitive environment and strategic initiatives such as mergers, acquisitions or dispositions and the market response to any such initiatives. An individual security may also be affected by factors relating to the industry or sector of the issuer or the securities markets as a whole, and conversely an industry or sector or the securities markets may be affected by a change in financial condition or other event affecting a single issuer.

*Investing in growth-oriented stocks* — Growth-oriented common stocks and other equity-type securities (such as preferred stocks, convertible preferred stocks and convertible bonds) may involve larger price swings and greater potential for loss than other types of investments. These risks may be even greater in the case of smaller capitalization stocks.

*Investing outside the United States* — Securities of issuers domiciled outside the United States or with significant operations or revenues outside the United States, and securities tied economically to countries outside the United States, may lose value because of adverse political, social, economic or market developments (including social instability, regional conflicts, terrorism and war) in the countries or regions in which the issuers are domiciled, operate or generate revenue or to which the securities are tied economically. These securities may also lose value due to changes in foreign currency exchange rates against the U.S. dollar and/or currencies of other countries. Issuers of these securities may be more susceptible to actions of foreign governments, such as nationalization, currency blockage or the imposition of price controls, sanctions, or punitive taxes, each of which could adversely impact the value of these securities. Securities markets in certain countries may be more volatile and/or less liquid than those in the United States. Investments outside the United States may also be subject to different regulatory, legal, accounting, auditing, financial reporting and recordkeeping requirements, and may be more difficult to value, than those in the United States. In addition, the value of investments outside the United States may be reduced by foreign taxes, including foreign withholding taxes on interest and dividends. Further, there may be increased risks of delayed settlement of securities purchased or sold by an underlying fund, which could impact the liquidity of the fund's portfolio. The risks of investing outside the United States may be heightened in connection with investments in emerging markets.

*Investing in emerging markets* — Investing in emerging markets may involve risks in addition to and greater than those generally associated with investing in the securities markets of developed countries. For instance, emerging market countries tend to have less developed political, economic and legal systems than those in developed countries. Accordingly, the governments of these countries may be less stable and more likely to intervene in the market economy, for example, by imposing capital controls, nationalizing a company or industry, placing restrictions on foreign ownership and on withdrawing sale proceeds of securities from the country, and/or imposing punitive taxes that could adversely affect the prices of securities. Information regarding issuers in emerging markets may be limited, incomplete or inaccurate, and such issuers may not be subject to regulatory, accounting, auditing, and financial reporting and recordkeeping standards comparable to those to which issuers in more developed markets are subject. The underlying fund's rights with respect to its investments in emerging markets, if any, will generally be governed by local law, which may make it difficult or impossible for the underlying fund to pursue legal remedies or to obtain and enforce judgments in local courts. In addition, the economies of these countries may be dependent on relatively few industries, may have limited access to capital and may be more susceptible to changes in local and global trade conditions and downturns in the world economy. Securities markets in these countries can also be relatively small and have substantially lower trading volumes. As a result, securities issued in these countries may be more volatile and less liquid, more vulnerable

3&nbsp;&nbsp;&nbsp;&nbsp; American Funds Insurance Series — Managed Risk Funds / Prospectus

------

to market manipulation, and more difficult to value, than securities issued in countries with more developed economies and/or markets. Less certainty with respect to security valuations may lead to additional challenges and risks in calculating the underlying fund's net asset value. Additionally, emerging markets are more likely to experience problems with the clearing and settling of trades and the holding of securities by banks, agents and depositories that are less established than those in developed countries.

*Investing in debt instruments* — The prices of, and the income generated by, bonds and other debt securities held by an underlying fund may be affected by factors such as the interest rates, maturities and credit quality of these securities.

Rising interest rates will generally cause the prices of bonds and other debt securities to fall. Also, when interest rates rise, issuers of debt securities that may be prepaid at any time, such as mortgage- or other asset-backed securities, are less likely to refinance existing debt securities, causing the average life of such securities to extend. A general change in interest rates may cause investors to sell debt securities on a large scale, which could also adversely affect the price and liquidity of debt securities and could also result in increased redemptions from the fund. Falling interest rates may cause an issuer to redeem, call or refinance a debt security before its stated maturity, which may result in the fund having to reinvest the proceeds in lower yielding securities. Longer maturity debt securities generally have greater sensitivity to changes in interest rates and may be subject to greater price fluctuations than shorter maturity debt securities.

Bonds and other debt securities are also subject to credit risk, which is the possibility that the credit strength of an issuer or guarantor will weaken or be perceived to be weaker, and/or an issuer of a debt security will fail to make timely payments of principal or interest and the security will go into default. Changes in actual or perceived creditworthiness may occur quickly. A downgrade or default affecting any of the fund's securities could cause the value of the fund's shares to decrease. Lower quality debt securities generally have higher rates of interest and may be subject to greater price fluctuations than higher quality debt securities. Credit risk is gauged, in part, by the credit ratings of the debt securities in which an underlying fund invests. However, ratings are only the opinions of the rating agencies issuing them and are not guarantees as to credit quality or an evaluation of market risk. The fund's investment adviser relies on its own credit analysts to research issuers and issues in assessing credit and default risks.

*Management* — The investment adviser to the fund and to the underlying funds actively manages each underlying fund's investments. Consequently, each underlying fund is subject to the risk that the methods and analyses, including models, tools and data, employed by the investment adviser in this process may be flawed or incorrect and may not produce the desired results. In addition, the fund is subject to the risk that the managed risk strategy or the methods employed by the subadviser in implementing the managed risk strategy may not produce the desired results. The occurrence of either or both of these events could cause the fund to lose value or its investment results to lag relevant benchmarks or other funds with similar objectives.

Your investment in the fund is not a bank deposit and is not insured or guaranteed by the Federal Deposit Insurance Corporation or any other governmental agency, entity or person. You should consider how this fund fits into your overall investment program.

**Investment results** The following bar chart shows how the investment results of the Class P1 shares of the fund have varied from year to year, and the following table shows how the fund's average annual total returns for various periods compare with a broad measure of securities market results and, if applicable, other measures of market results that reflect the fund's investment universe. This information provides some indication of the risks of investing in the fund. Past investment results (before and after taxes) are not predictive of future investment results. Figures shown reflect fees and expenses associated with an investment in the fund, but do not reflect insurance contract fees and expenses. If insurance contract fees and expenses were included, results would have been lower. Updated information on the fund's investment results can be obtained by visiting capitalgroup.com/afis.

**Purchase and sale of fund shares** Shares of the fund are not sold directly to the general public. The fund is offered only as an underlying investment option for variable insurance contracts, and insurance company separate accounts and qualified feeder funds — and not the holders of variable insurance contracts — are the shareholders of the fund. Although the fund does not require a minimum amount for initial or subsequent purchases from insurance companies, your insurance company may impose investment minimums for your purchase of the fund.

You may sell (redeem) shares on any business day. You must sell (redeem) shares through your insurance company.

**Tax information** See your variable insurance contract prospectus for information regarding the federal income tax treatment of your variable insurance contract and related distributions.

**Payments to broker-dealers and other financial intermediaries** The fund is not sold directly to the general public but instead is offered as an underlying investment option for variable insurance contracts. The fund and its related companies may make payments to the sponsoring insurance company (or its affiliates) for distribution and/or other services. These payments may be a factor that the insurance company considers in including the fund as an underlying investment option in the variable insurance contract. The prospectus (or other offering document) for your variable insurance contract may contain additional information about these payments.

**Investment objectives, strategies and risks** 

**Managed Risk EUPAC Fund** The fund's investment objective is to provide you with long-term growth of capital while seeking to manage volatility and provide downside protection. While it has no present intention to do so, the fund's board may change the fund's investment objective without shareholder approval upon 60 days' prior written notice to shareholders. The fund pursues its investment objective by investing in Class 1 shares of the American Funds Insurance Series – EUPAC Fund (the "EUPAC Fund") and the American Funds Insurance Series – The Bond Fund of America ("The Bond Fund of America"), while seeking to manage portfolio volatility and risk of loss primarily through the use of exchange-traded options and futures contracts.

The fund normally seeks to invest 85% of its assets in the EUPAC Fund. The investment objective of the EUPAC Fund is to provide long-term growth of capital. The EUPAC Fund invests primarily in common stocks in Europe and the Pacific Basin that the investment adviser believes have the potential for growth. Growth stocks are stocks that the underlying fund's investment adviser believes have the potential for above average capital appreciation.

Normally, the EUPAC Fund will invest at least 80% of its net assets in securities of issuers in Europe and the Pacific Basin. A country will be considered part of Europe if it is part of the MSCI European indexes, and part of the Pacific Basin if any of its borders touches the Pacific Ocean. In determining the domicile of an issuer, the underlying fund's investment adviser will generally look to the determination of MSCI Inc. (MSCI) for equity securities and Bloomberg for debt securities. In certain limited circumstances (including where relevant data is unavailable or the nature of a holding warrants special considerations), the adviser may also take into account additional factors, as applicable, including where the issuer's securities are listed; where the issuer is legally organized, maintains principal corporate offices, conducts its principal operations, generates revenues and/or has credit risk exposure; and the source of guarantees, if any, of such securities. The fund may invest a portion of its assets in common stocks and other securities of companies in emerging markets.

The fund invests the remainder of its assets in The Bond Fund of America and in cash, financial futures and options as part of the managed risk strategy. The investment objective of The Bond Fund of America is to provide as high a level of current income as is consistent with the preservation of capital. The Bond Fund of America seeks to maximize your level of current income and preserve your capital by investing primarily in bonds. Normally, The Bond Fund of America invests at least 80% of its assets in bonds and other debt securities, which may be represented by derivatives. The Bond Fund of America invests at least 60% of its assets in debt securities (excluding derivatives) rated A3 or better or A- or better by Nationally Recognized Statistical Rating Organizations, or NRSROs, designated by the underlying fund's investment adviser or in debt securities that are unrated but determined to be of equivalent quality by the fund's investment adviser, and in U.S. government securities, money market instruments, cash or cash equivalents.

The Bond Fund of America may invest, subject to the restrictions above, in contracts for future delivery of mortgage-backed securities, such as to-be-announced contracts and mortgage rolls. Although The Bond Fund of America may generally invest in debt securities of any maturity or duration, such contracts are normally of short duration and may be replaced by another contract prior to maturity. Each such transaction is reflected as turnover in The Bond Fund of America's portfolio, resulting in a higher portfolio turnover rate than funds that do not employ this investment strategy.

The Bond Fund of America may invest in debt securities and mortgage-backed securities issued by government-sponsored entities and federal agencies and instrumentalities that are not backed by the full faith and credit of the U.S. government. The Bond Fund of America may invest in debt securities of any maturity or duration. Duration is a measure used to determine the sensitivity of a security's price to changes in interest rates. The longer a security's duration, the more sensitive it will be to changes in interest rates.

The Bond Fund of America may invest in inflation-linked bonds issued by U.S. and non-U.S. governments, their agencies or instrumentalities and corporations. Inflation-linked bonds are structured to protect against inflation by linking the bond's principal and interest payments to an inflation index, such as the Consumer Price Index for Urban Consumers, so that principal and interest adjust or reflect changes in the index.

The Bond Fund of America may invest in futures contracts and swaps, which are types of derivatives. A derivative is a financial contract, the value of which is based on the value of an underlying financial asset (such as a stock, bond or currency), a reference rate or a market index.

The Bond Fund of America may invest in futures contracts and interest rate swaps in order to seek to manage The Bond Fund of America's sensitivity to interest rates, and in credit default swap indices, or CDSIs, in order to assume exposure to a diversified portfolio of credits or to hedge against existing credit risks. A futures contract is a standardized exchange-traded agreement to buy or sell a specific quantity of an underlying asset, rate or index at an agreed-upon price at a stipulated future date. An interest rate swap is an agreement between two parties to exchange or swap payments based on changes in one or more interest rates, one of which is typically fixed and the other of which is typically a floating rate based on a designated short-term interest rate, such as the Secured Overnight Financing Rate, prime rate or other benchmark. A CDSI is based on a portfolio of credit default swaps with similar characteristics, such as credit default swaps on high-yield bonds. In a typical CDSI transaction, one party – the protection buyer – is obligated to pay the other party – the protection seller – a stream of periodic payments over the term of the contract, provided generally that no credit event on an underlying reference obligation has occurred. If such a credit event has occurred, the protection seller must pay the protection buyer the loss on those credits.

The Bond Fund of America may also enter into currency transactions to provide for the purchase or sale of a currency needed to purchase a security denominated in that currency. In addition, The Bond Fund of America may enter into forward currency contracts to protect against changes in currency exchange rates. The Bond Fund of America may also enter into forward currency contracts to seek to increase total return. A forward currency contract is an agreement to purchase or sell a specific currency at a future date at a fixed price.

The Bond Fund of America may invest up to 5% of its assets in debt securities rated Ba1 or below and BB+ or below by NRSROs designated by the underlying fund's investment adviser, or in debt securities that are unrated but determined to be of equivalent quality by the underlying fund's investment adviser. Such securities are sometimes referred to as "junk bonds."

The fund's investment in The Bond Fund of America seeks to provide a level of diversification across asset classes. Because different asset classes often react differently to changes in market conditions, such diversification seeks to manage the fund's risk to market changes, including stock market declines. Additionally, the fund employs a risk-management overlay or managed risk strategy. The managed risk strategy consists of using hedge instruments — primarily exchange-traded futures contracts and/or exchange-traded put options — to attempt to stabilize the volatility of the fund around a target volatility level and to seek to reduce the downside exposure of the fund. "Volatility" in this context means variance in the fund's investment results. The fund employs a subadviser to select individual put options and futures contracts on equity indexes of U.S. markets and markets outside the United States that the subadviser believes are correlated to the underlying fund's equity exposure. These instruments are selected based on the subadviser's analysis of the relation of various equity indexes to the underlying fund's portfolio. In addition, the subadviser will monitor liquidity levels of relevant options and futures contracts and transparency provided by exchanges as the counterparties in hedging transactions. The target volatility level will be set from time to time by the investment adviser and the subadviser and may be adjusted if deemed advisable in the judgment of the investment adviser and the subadviser. The subadviser will regularly adjust the level of exchange-traded futures contracts to seek to manage the overall net risk level of the fund. The subadviser may also seek to hedge the fund's currency risk related to its exposure to equity index options and futures denominated in currencies other than the U.S. dollar.

Prior to May 1, 2026, the fund was called Managed Risk International Fund .

The subadviser regularly adjusts the level of exchange-traded options and futures contracts held by the fund to seek to manage the fund's overall net risk level. During periods of generally rising equity security prices, the subadviser will normally increase the target level of protection in the fund to seek to protect the growing value of the fund's portfolio. During or after severe market downturns, however, the fund's subadviser is expected to realize gains for the fund on the fund's put options and short futures positions and the amount of options and futures held by the fund will likely decrease. Even in periods of low volatility in the equity markets, the subadviser will continue to employ exchange-traded equity index put options to seek to preserve gains in favorable market conditions and to reduce losses in adverse market conditions. During such periods of low equity market volatility, the subadviser may also continue to use exchange-traded equity index futures contracts for hedging purposes, though it need not necessarily do so. In the event of a sudden market dislocation, the managed risk strategy may not provide the same downside protection as in other periods. Accordingly, in certain market conditions, the fund may also purchase exchange-traded equity index call options, write (or sell) exchange-traded equity index put and call options and/or take net long positions in exchange-traded equity index futures contracts. In addition, under certain market conditions (including during periods of low equity market volatility, when the subadviser may employ exchange-traded equity index futures to a lesser degree or not at all), the subadviser reserves the right to purchase or sell exchange-traded interest rate futures, including futures contracts on U.S. Treasury bonds, to seek to manage interest rate risk.

From time to time, including during severe market dislocations, the fund may adjust its managed risk strategy if advisable in the judgment of the fund's investment adviser and subadviser. For example, if the market for swaps moves, as is expected, from a largely over-the-counter market to an exchange-traded market as a result of recent regulatory changes, the subadviser may use exchange-traded swaps to seek to hedge interest rate risk if the fund's investment adviser and subadviser determine that the exchange-traded swaps market has become similar in depth and substance to that of the exchange-traded options and futures markets. Before adjusting the fund's managed risk strategy, the fund's investment adviser and subadviser may consult with insurance companies that offer the fund as an underlying investment option for variable contracts; provided, however that any adjustment will be made in the judgment of the investment adviser and the subadviser. Any such adjustment may not have the desired positive effect, and could potentially have further adverse effects, on the fund's investment results.

The subadviser will purchase or sell futures contracts through a futures commission merchant, or FCM. The fund may be required to own cash or other liquid assets, including U.S. Treasury securities, and post these assets with an FCM or broker as collateral to cover the fund's obligations under its futures contracts. Upon entering into a futures contract, for example, the fund will be required to deposit with the FCM an amount of cash (or other liquid assets, including U.S. Treasury securities) for collateral, or initial margin, that will be held at the clearinghouse or exchange in the name of the FCM. On a daily basis, the fund will be required to post additional cash with the FCM if a futures contract loses value or will receive cash if a futures contract gains in value. This cash, known as variation margin, may be held intraday at the FCM. Cash received by the fund may be invested in U.S. Treasury futures.

The fund or an underlying fund may also hold cash or cash equivalents, including commercial paper and short-term securities issued by the U.S. government, its agencies and instrumentalities. The fund may also hold money market fund shares as part of its cash position. The percentage of the fund or an underlying fund invested in such holdings varies and depends on various factors, including market conditions and purchases and redemptions of fund shares. The investment adviser may determine that it is appropriate to invest a substantial portion of the fund's assets in such instruments in response to certain circumstances, such as periods of market turmoil. For temporary defensive purposes, the fund or an underlying fund may invest without limitation in such instruments. A larger percentage of such holdings could moderate a fund's investment results in a period of rising market prices. Alternatively, a larger percentage of such holdings could reduce the magnitude of a fund's loss in a period of falling market prices and provide liquidity to make additional investments or to meet redemptions.

An underlying fund may invest in certain other funds managed by the investment adviser or its affiliates ("Central Funds") to more effectively invest in a diversified set of securities in a specific asset class such as money market instruments, bonds and other securities. Shares of Central Funds are only offered for purchase to the fund's investment adviser and its affiliates and other funds, investment vehicles and accounts managed by the fund's investment adviser and its affiliates. Central Funds do not charge management fees. As a result, an underlying fund does not bear additional management fees when investing in Central Funds, but an underlying fund does bear its proportionate share of Central Fund expenses. The investment results of the portions of an underlying fund's assets invested in the Central Funds will be based upon the investment results of the Central Funds.

The investment adviser may consider environmental, social and governance ("ESG") factors that, depending on the facts and circumstances, are material to the value of an issuer or instrument. ESG factors may include, but are not limited to, environmental issues (e.g., water use, emission levels, waste, environmental remediation), social issues (e.g., human capital, health and safety, changing customer behavior) or governance issues (e.g., board composition, executive compensation, shareholder dilution).

The following are principal risks associated with investing in the fund.

*Fund structure* — The fund invests in underlying funds and incurs expenses related to those underlying funds. In addition, investors in the fund will incur fees to pay for certain expenses related to the operations of the fund. An investor holding the underlying funds directly would incur lower overall expenses but would not receive the benefit of the managed risk strategy. Additionally, in accordance with an exemption under the Investment Company Act of 1940, as amended, the investment adviser considers only proprietary funds when selecting underlying investment options and allocations. This means that the fund's investment adviser does not, nor does it expect to, consider any unaffiliated funds as underlying investment options for the fund. This strategy could raise certain conflicts of interest when determining the overall asset allocation of the fund or choosing underlying investments for the fund, including the selection of funds that result in greater compensation to the adviser or funds with relatively lower historical investment results. The investment adviser has policies and procedures designed to mitigate material conflicts of interest that may arise in connection with its management of the fund.

*Underlying fund risks* — Because the fund's investments consist of investments in underlying funds, the fund's risks are directly related to the risks of those underlying funds. For this reason, it is important to understand the risks associated with investing both in the fund and in each of the underlying funds.

*Investing in derivatives* — The use of derivatives involves a variety of risks, which may be different from, or greater than, the risks associated with investing in traditional securities, such as stocks and bonds. Changes in the value of a derivative may not correlate perfectly with, and may be more sensitive to market events than, the underlying asset, rate or index, and a derivative instrument may cause the fund or an underlying fund to lose significantly more than its initial investment. Derivatives may be difficult to value, difficult for the fund or an underlying fund to buy or sell at an opportune time or price and difficult, or even impossible, to terminate or otherwise offset. A fund's use of derivatives may result in losses to the fund, and investing in derivatives may reduce the fund's returns and increase the fund's price volatility. A fund's counterparty to a derivative transaction (including, if applicable, the fund's clearing broker, the derivatives exchange or the clearinghouse) may be unable or unwilling to honor its financial obligations in respect of the transaction. In certain cases, the fund or an underlying fund may be hindered or delayed in exercising remedies against or closing out derivative instruments with a counterparty, which may result in additional losses. Derivatives are also subject to operational risk (such as documentation issues, settlement issues and systems failures) and legal risk (such as insufficient documentation, insufficient capacity or authority of a counterparty, and issues with the legality or enforceability of a contract).

*Investing in options and futures contracts* — In addition to the risks generally associated with investing in derivative instruments, options and futures contracts are subject to the creditworthiness of the clearing organizations, exchanges and, in the case of futures, futures commission merchants with which the fund transacts. While both options and futures contracts are generally liquid instruments, under certain market conditions, options and futures may be deemed to be illiquid. For example, the fund may be temporarily prohibited from closing out its position in an options or futures contract if intraday price change limits or limits on trading volume imposed by the applicable exchange are triggered. If the fund is unable to close out a position on an options or futures contract, the fund would remain subject to the risk of adverse price movements until the fund is able to close out the position in question. The ability of the fund to successfully utilize options and futures contracts may depend in part upon the ability of the fund's investment adviser or subadviser to accurately forecast interest rates and other economic factors and to assess and predict the impact of such economic factors on the options and futures in which the fund invests. If the investment adviser or subadviser incorrectly forecasts economic developments or incorrectly predicts the impact of such developments on the options and futures in which it invests, the fund could suffer losses. Whereas the risk of loss on a put option purchased by the fund is limited to the initial cost of the option, the amount of a potential loss on a futures contract could greatly exceed the relatively small initial amount invested in entering the futures position.

*Hedging* — There may be imperfect or even negative correlation between the prices of the options and futures contracts in which the fund invests and the prices of the underlying securities or indexes which the fund seeks to hedge. For example, options and futures contracts may not provide an effective hedge because changes in options and futures contract prices may not track those of the underlying securities or indexes they are intended to hedge. In addition, there are significant differences between the securities market, on the one hand, and the options and futures markets, on the other, that could result in an imperfect correlation between the markets, causing a given hedge not to achieve its objectives. The degree of imperfection of correlation depends on circumstances such as variations in speculative market demand for options and futures, including technical influences in options and futures trading, and differences between the financial instruments being hedged and the instruments underlying the standard contracts available for trading. A decision as to whether, when and how to hedge involves the exercise of skill and judgment, and even a well-conceived hedge may be unsuccessful to some degree because of market behavior or unexpected interest rate trends. In addition, the fund's investment in exchange-traded options and futures and their resulting costs could limit the fund's gains in rising markets relative to those of the underlying funds, or to those of unhedged funds in general.

*Short positions* — The fund may suffer losses from short positions in futures contracts. Losses from short positions in futures contracts occur when the underlying index increases in value. As the underlying index increases in value, the holder of the short position in the corresponding futures contract is required to pay the difference in value of the futures contract resulting from the increase in the index on a daily basis. Losses from a short position in an index futures contract could potentially be very large if the value of the underlying index rises dramatically in a short period of time.

American Funds Insurance Series — Managed Risk Funds / Prospectus&nbsp;&nbsp;&nbsp;&nbsp; 8

------

*Market conditions* — The prices of, and the income generated by, the securities held by an underlying fund may decline – sometimes rapidly or unpredictably – due to various factors, including events or conditions affecting the general economy or particular industries or companies; overall market changes; local, regional or global political, social or economic instability; governmental, governmental agency or central bank responses to economic conditions; levels of public debt and deficits; changes in inflation rates; and currency exchange rate, interest rate and commodity price fluctuations.

Economies and financial markets throughout the world are highly interconnected. Economic, financial or political events, trading and tariff arrangements, wars, terrorism, cybersecurity events, natural disasters, public health emergencies (such as the spread of infectious disease), bank failures and other circumstances in one country or region, including actions taken by governmental or quasi-governmental authorities in response to any of the foregoing, could have impacts on global economies or markets. As a result, whether or not an underlying fund invests in securities of issuers located in or with significant exposure to the countries affected, the value and liquidity of an underlying fund's investments may be negatively affected by developments in other countries and regions.

*Issuer risks* — The prices of, and the income generated by, securities held by an underlying fund may decline in response to various factors directly related to the issuers of such securities, including reduced demand for an issuer's goods or services, poor management performance, major litigation, investigations or other controversies related to the issuer, changes in the issuer's financial condition or credit rating, changes in government regulations affecting the issuer or its competitive environment and strategic initiatives such as mergers, acquisitions or dispositions and the market response to any such initiatives. An individual security may also be affected by factors relating to the industry or sector of the issuer or the securities markets as a whole, and conversely an industry or sector or the securities markets may be affected by a change in financial condition or other event affecting a single issuer. To the extent that the securities of issuers in the same or related industries or sectors behave similarly to each other, and these issuers make up a sizeable portion of the market, events affecting one issuer, industry or sector or the securities markets generally may have a larger impact. If such issuers represent a substantial portion of major market indices, or the economy, a downturn in their stock prices may have a disproportionate adverse effect on the overall equity markets, even if other segments of the market perform well. The underlying fund's portfolio managers invest in issuers based on their level of investment conviction. At times, the underlying fund may invest more significantly in a single issuer, which could increase the underlying fund's volatility and the risk of loss arising from the factors described above.

*Investing in growth-oriented stocks* — Growth-oriented common stocks and other equity-type securities (such as preferred stocks, convertible preferred stocks and convertible bonds) may involve larger price swings and greater potential for loss than other types of investments. These risks may be even greater in the case of smaller capitalization stocks.

*Investing outside the United States* — Securities of issuers domiciled outside the United States or with significant operations or revenues outside the United States, and securities tied economically to countries outside the United States, may lose value because of adverse political, social, economic or market developments (including social instability, regional conflicts, terrorism and war) in the countries or regions in which the issuers are domiciled, operate or generate revenue or to which the securities are tied economically. These securities may also lose value due to changes in foreign currency exchange rates against the U.S. dollar and/or currencies of other countries. Issuers of these securities may be more susceptible to actions of foreign governments, such as nationalization, currency blockage or the imposition of price controls, sanctions, or punitive taxes, each of which could adversely impact the value of these securities. Securities markets in certain countries may be more volatile and/or less liquid than those in the United States. Investments outside the United States may also be subject to different regulatory, legal, accounting, auditing, financial reporting and recordkeeping requirements, and may be more difficult to value, than those in the United States. In addition, the value of investments outside the United States may be reduced by foreign taxes, including foreign withholding taxes on interest and dividends. Further, there may be increased risks of delayed settlement of securities purchased or sold by an underlying fund, which could impact the liquidity of the fund's portfolio. The risks of investing outside the United States may be heightened in connection with investments in emerging markets.

*Investing in emerging markets* — Investing in emerging markets may involve risks in addition to and greater than those generally associated with investing in the securities markets of developed countries. For instance, emerging market countries tend to have less developed political, economic and legal systems than those in developed countries. Accordingly, the governments of these countries may be less stable and more likely to intervene in the market economy, for example, by imposing capital controls, nationalizing a company or industry, placing restrictions on foreign ownership and on withdrawing sale proceeds of securities from the country, and/or imposing punitive taxes that could adversely affect the prices of securities. Information regarding issuers in emerging markets may be limited, incomplete or inaccurate, and such issuers may not be subject to regulatory, accounting, auditing, and financial reporting and recordkeeping standards comparable to those to which issuers in more developed markets are subject. The underlying fund's rights with respect to its investments in emerging markets, if any, will generally be governed by local law, which may make it difficult or impossible for the underlying fund to pursue legal remedies or to obtain and enforce judgments in local courts. In addition, the economies of these countries may be dependent on relatively few industries, may have limited access to capital and may be more susceptible to changes in local and global trade conditions and downturns in the world economy. Securities markets in these countries can also be relatively small and have substantially lower trading volumes. As a result, securities issued in these countries may be more volatile and less liquid, more vulnerable to market manipulation, and more difficult to value, than securities issued in countries with more developed economies and/or markets. Less certainty with respect to security valuations may lead to additional challenges and risks in calculating the underlying fund's net asset value. Additionally, emerging markets are more likely to experience problems with the clearing and settling of trades and the holding of securities by banks, agents and depositories that are less established than those in developed countries.

*Investing in debt instruments* — The prices of, and the income generated by, bonds and other debt securities held by an underlying fund may be affected by factors such as the interest rates, maturities and credit quality of these securities.

Rising interest rates will generally cause the prices of bonds and other debt securities to fall. Also, when interest rates rise, issuers of debt securities that may be prepaid at any time, such as mortgage- or other asset-backed securities, are less likely to refinance existing debt

9&nbsp;&nbsp;&nbsp;&nbsp; American Funds Insurance Series — Managed Risk Funds / Prospectus

------

securities, causing the average life of such securities to extend. A general change in interest rates may cause investors to sell debt securities on a large scale, which could also adversely affect the price and liquidity of debt securities and could also result in increased redemptions from the fund. Falling interest rates may cause an issuer to redeem, call or refinance a debt security before its stated maturity, which may result in the fund having to reinvest the proceeds in lower yielding securities. Longer maturity debt securities generally have greater sensitivity to changes in interest rates and may be subject to greater price fluctuations than shorter maturity debt securities.

Bonds and other debt securities are also subject to credit risk, which is the possibility that the credit strength of an issuer or guarantor will weaken or be perceived to be weaker, and/or an issuer of a debt security will fail to make timely payments of principal or interest and the security will go into default. Changes in actual or perceived creditworthiness may occur quickly. A downgrade or default affecting any of the fund's securities could cause the value of the fund's shares to decrease. Lower quality debt securities generally have higher rates of interest and may be subject to greater price fluctuations than higher quality debt securities. Credit risk is gauged, in part, by the credit ratings of the debt securities in which an underlying fund invests. However, ratings are only the opinions of the rating agencies issuing them and are not guarantees as to credit quality or an evaluation of market risk. The fund's investment adviser relies on its own credit analysts to research issuers and issues in assessing credit and default risks.

*Management* — The investment adviser to the fund and to the underlying funds actively manages each underlying fund's investments. Consequently, each underlying fund is subject to the risk that the methods and analyses, including models, tools and data, employed by the investment adviser in this process may be flawed or incorrect and may not produce the desired results. In addition, the fund is subject to the risk that the managed risk strategy or the methods employed by the subadviser in implementing the managed risk strategy may not produce the desired results. The occurrence of either or both of these events could cause the fund to lose value or its investment results to lag relevant benchmarks or other funds with similar objectives.

The following are additional risks associated with investing in the fund.

*Exposure to country, region, industry or sector* — Subject to its investment limitations, an underlying fund may have significant exposure to a particular country, region, industry or sector. Such exposure may cause the underlying fund to be more impacted by risks relating to and developments affecting the country, region, industry or sector, and thus its net asset value may be more volatile, than a fund without such levels of exposure. For example, if an underlying fund has significant exposure in a particular country, then social, economic, regulatory or other issues that negatively affect that country may have a greater impact on the underlying fund than on a fund that is more geographically diversified.

*Investing in depositary receipts* — Depositary receipts are securities that evidence ownership interests in, and represent the right to receive, a security or a pool of securities that have been deposited with a bank or trust depository. Such securities may be less liquid or may trade at a lower price than the underlying securities of the issuer. Additionally, receipt of corporate information about the underlying issuer and proxy disclosure may not be timely and there may not be a correlation between such information and the market value of the depositary receipts.

*Liquidity risk* — Certain underlying fund holdings may be or may become difficult or impossible to sell, particularly during times of market turmoil. Liquidity may be impacted by the lack of an active market for a holding, legal or contractual restrictions on resale, or the reduced number and capacity of market participants to make a market in such holding. Market prices for less liquid or illiquid holdings may be volatile or difficult to determine, and reduced liquidity may have an adverse impact on the market price of such holdings. Additionally, the sale of less liquid or illiquid holdings may involve substantial delays (including delays in settlement) and additional costs and the underlying fund may be unable to sell such holdings when necessary to meet its liquidity needs or to try to limit losses, or may be forced to sell at a loss.

*Investing in mortgage-related and other asset-backed securities* — Mortgage-related securities, such as mortgage-backed securities, and other asset-backed securities, include debt obligations that represent interests in pools of mortgages or other income-bearing assets, such as residential mortgage loans, home equity loans, mortgages on commercial buildings, consumer loans and equipment leases. While such securities are subject to the risks associated with investments in debt instruments generally (for example, credit, extension and interest rate risks), they are also subject to other and different risks. Mortgage-backed and other asset-backed securities are subject to changes in the payment patterns of borrowers of the underlying debt, potentially increasing the volatility of the securities and an underlying fund's net asset value. When interest rates fall, borrowers are more likely to refinance or prepay their debt before its stated maturity. This may result in an underlying fund having to reinvest the proceeds in lower yielding securities, effectively reducing the underlying fund's income. Conversely, if interest rates rise and borrowers repay their debt more slowly than expected, the time in which the mortgage-backed and other asset-backed securities are paid off could be extended, reducing an underlying fund's cash available for reinvestment in higher yielding securities. Mortgage-backed securities are also subject to the risk that underlying borrowers will be unable to meet their obligations and the value of property that secures the mortgages may decline in value and be insufficient, upon foreclosure, to repay the associated loans. Investments in asset-backed securities are subject to similar risks, as well as additional risks associated with the assets underlying those securities.

*Investments in future delivery contracts* — An underlying fund may enter into transactions involving future delivery contracts, such as to-be-announced (TBA) contracts and mortgage dollar rolls. These contracts involve the purchase or sale of mortgage-backed securities for settlement at a future date and predetermined price. When an underlying fund enters into a TBA commitment for the sale of mortgage-backed securities (which may be referred to as having a short position in such TBA securities), an underlying fund may or may not hold the types of mortgage-backed securities required to be delivered. An underlying fund may choose to roll these transactions in lieu of settling them.

When an underlying fund rolls the purchase of these types of future delivery transactions, an underlying fund simultaneously sells the mortgage-backed securities for delivery in the current month and repurchases substantially similar securities for delivery at a future date at

American Funds Insurance Series — Managed Risk Funds / Prospectus&nbsp;&nbsp;&nbsp;&nbsp; 10

------

a predetermined price. When an underlying fund rolls the sale of these transactions rather than settling them, an underlying fund simultaneously purchases the mortgage-backed securities for delivery in the current month and sells substantially similar securities for delivery at a future date at a predetermined price. Such roll transactions can increase the turnover rate of an underlying fund and may increase the risk that market prices may move unfavorably between the original and new contracts, potentially resulting in losses or reduced returns for an underlying fund.

*Investing in securities backed by the U.S. government* — U.S. government securities are subject to market risk, interest rate risk and credit risk. Securities backed by the U.S. Treasury or the full faith and credit of the U.S. government are guaranteed only as to the timely payment of interest and principal when held to maturity. Accordingly, the current market values for these securities will fluctuate with changes in interest rates and the credit rating of the U.S. government. Notwithstanding that these securities are backed by the full faith and credit of the U.S. government, circumstances could arise that would prevent or delay the payment of interest or principal on these securities, which could adversely affect their value and cause the fund to suffer losses. Such an event could lead to significant disruptions in U.S. and global markets.

Securities issued by U.S. government-sponsored entities and federal agencies and instrumentalities that are not backed by the full faith and credit of the U.S. government are neither issued nor guaranteed by the U.S. government.

*Investing in inflation-linked bonds* — The values of inflation-linked bonds generally fluctuate in response to changes in real interest rates — i.e., rates of interest after factoring in inflation. A rise in real interest rates may cause the prices of inflation-linked securities to fall, while a decline in real interest rates may cause the prices to increase. Inflation-linked bonds may experience greater losses than other debt securities with similar durations when real interest rates rise faster than nominal interest rates. There can be no assurance that the value of an inflation-linked security will be directly correlated to changes in interest rates; for example, if interest rates rise for reasons other than inflation, the increase may not be reflected in the security's inflation measure.

Investing in inflation-linked bonds may also reduce an underlying fund's distributable income during periods of deflation. If prices for goods and services decline throughout the economy, the principal and income on inflation-linked securities may decline and result in losses to an underlying fund.

*Investing in swaps* — Swaps, including interest rate swaps and credit default swap indices, or CDSIs, are subject to many of the risks generally associated with investing in derivative instruments. Additionally, although swaps require no initial investment or only a small initial investment in the form of a deposit of initial margin, the amount of a potential loss on a swap could greatly exceed the initial amount invested. The use of swaps involves the risk that the investment adviser will not accurately predict anticipated changes in interest rates or other economic factors, which may result in losses to an underlying fund. If an underlying fund enters into a bilaterally negotiated swap, the counterparty may fail to perform in accordance with the terms of the swap. If a counterparty defaults on its obligations under a swap, the underlying fund may lose any amount it expected to receive from the counterparty, potentially including amounts in excess of the underlying fund's initial investment. Certain swaps are subject to mandatory central clearing or may be eligible for voluntary central clearing. Although clearing interposes a central clearinghouse as the ultimate counterparty to each participant's swap, central clearing will not eliminate (but may decrease) counterparty risk relative to uncleared bilateral swaps. Some swaps, such as CDSIs, may be dependent on both the individual credit of an underlying fund's counterparty and on the credit of one or more issuers of any underlying assets. If an underlying fund does not correctly evaluate the creditworthiness of its counterparty and, where applicable, of issuers of any underlying reference assets, the underlying fund's investment in a swap may result in losses to the underlying fund.

*Currency transactions* — In addition to the risks generally associated with investing in derivative instruments, the use of forward currency contracts involves the risk that currency movements will not be accurately predicted by the investment adviser, which could result in losses to an underlying fund. While entering into forward currency contracts could minimize the risk of loss due to a decline in the value of the hedged currency, it could also limit any potential gain that may result from an increase in the value of the currency. Additionally, the adviser may use forward currency contracts to increase exposure to a certain currency or to shift exposure to currency fluctuations from one country to another. Forward currency contracts may expose an underlying fund to potential gains and losses in excess of the initial amount invested.

*Interest rate risk* — The values and liquidity of the securities held by an underlying fund may be affected by changing interest rates. For example, the values of these securities may decline when interest rates rise and increase when interest rates fall. Longer maturity debt securities generally have greater sensitivity to changes in interest rates and may be subject to greater price fluctuations than shorter maturity debt securities. An underlying fund may invest in variable and floating rate securities. When the underlying fund holds variable or floating rate securities, a decrease in market interest rates will adversely affect the income received from such securities and the net asset value of the fund's shares. Although the values of such securities are generally less sensitive to interest rate changes than those of other debt securities, the value of variable and floating rate securities may decline if their interest rates do not rise as quickly, or as much, as market interest rates. Conversely, floating rate securities will not generally increase in value if interest rates decline. During periods of extremely low short-term interest rates, an underlying fund may not be able to maintain a positive yield or total return and, in relatively low interest rate environments, there are heightened risks associated with rising interest rates.

*Portfolio turnover* — The underlying fund may engage in frequent and active trading of its portfolio securities. Higher portfolio turnover may involve correspondingly greater transaction costs in the form of dealer spreads, brokerage commissions and other transaction costs on the sale of securities and on reinvestment in other securities. The sale of portfolio securities may also result in the realization of net capital gains, which are taxable when distributed to shareholders, unless the shareholder is exempt from taxation or his or her account is tax-favored. These costs and tax effects may adversely affect the underlying fund's returns to shareholders. The fund's portfolio turnover rate may vary from year to year, as well as within a year.

*Lending of portfolio securities —* Securities lending involves risks, including the risk that the loaned securities may not be returned in a timely manner or at all, which would interfere with the fund's ability to vote proxies or settle transactions, and/or the risk of a counterparty default. Additionally, the fund may lose money from the reinvestment of collateral received on loaned securities in investments that decline in value, default or do not perform as expected.

*Cybersecurity breaches* — The underlying fund may be subject to operational and information security risks through breaches in cybersecurity. Cybersecurity breaches can result from deliberate attacks or unintentional events, including "ransomware" attacks, the injection of computer viruses or malicious software code, the use of vulnerabilities in code to gain unauthorized access to digital information systems, networks or devices, or external attacks such as denial-of-service attacks on the investment adviser's or an affiliate's website that could render the underlying fund's network services unavailable to intended end-users. These breaches may, among other things, lead to the unauthorized release of confidential information, misuse of the underlying fund's assets or sensitive information, the disruption of the underlying fund's operational capacity, the inability of underlying fund shareholders to transact business, or the destruction of the underlying fund's physical infrastructure, equipment or operating systems. These events could cause the underlying fund to violate applicable privacy and other laws and could subject the underlying fund to reputational damage, additional costs associated with corrective measures and/or financial loss. The underlying fund may also be subject to additional risks if its third-party service providers, such as the underlying fund's investment adviser, transfer agent, custodian, administrators and other financial intermediaries, experience similar cybersecurity breaches and potential outcomes. Cybersecurity risks may also impact issuers of securities in which the underlying fund invests, which may cause the underlying fund's investments in such issuers to lose value.

*Large shareholder transactions risk* — The underlying fund may experience adverse effects when shareholders, including other underlying funds or accounts advised by the investment adviser, purchase or redeem, individually or in the aggregate, large amounts of shares relative to the size of the underlying fund. For example, when the investment adviser changes allocations in other underlying funds and accounts it manages, such changes may result in shareholder transactions in the underlying fund that are large relative to the size of the underlying fund. Such large shareholder redemptions may cause the underlying fund to sell portfolio securities at times when it would not otherwise do so, which may negatively impact the underlying fund's net asset value and liquidity. Similarly, large underlying fund share purchases may adversely affect the underlying fund's performance to the extent that the underlying fund is delayed in investing new cash and is required to maintain a larger cash position than it ordinarily would. These transactions may also accelerate the realization of taxable income to shareholders if such sales of investments resulted in gains, and may also increase transaction costs. In addition, a large redemption could result in the underlying fund's current expenses being allocated over a smaller asset base, leading to an increase in the underlying fund's expense ratio. These risks are heightened when the underlying fund is small.

In addition to the principal investment strategies described above, the fund has other investment practices that are described in the statement of additional information, which includes a description of other risks related to the fund's principal investment strategies and other investment practices. The fund's investment results will depend on the ability of the fund's investment adviser to navigate the risks discussed above as well as those described in the statement of additional information.

**Fund comparative indexes** — The MSCI All Country World ex USA Index is a free float-adjusted market capitalization-weighted index that is designed to measure equity market results in the global developed and emerging markets, excluding the United States. The index consists of more than 40 developed and emerging market country indexes. Results reflect dividends gross of withholding taxes through December 31, 2000, and dividends net of withholding taxes thereafter. This index is unmanaged, and its results include reinvested dividends and/or distributions but do not reflect the effect of sales charges, commissions, account fees, expenses or U.S. federal income taxes. The S&P Managed Risk Index Series is designed to simulate a dynamic protective portfolio that allocates between the underlying equity index and cash, based on realized volatilities of the underlying equity and bond indices, while maintaining a fixed allocation to the underlying bond index. These indices are generated and published under agreements between S&P Dow Jones Indices and Milliman Financial Risk Management LLC. This index is unmanaged, and its results include reinvested dividends and/or distributions but do not reflect the effect of sales charges, commissions, account fees, expenses or U.S. federal income taxes.

**Portfolio holdings** A description of the fund's policies and procedures regarding disclosure of information about its portfolio holdings is available in the statement of additional information.

**Information regarding the underlying funds** The investment objectives and principal investment strategies of the underlying funds are summarized below and on the following pages. They should not be construed as an offer to purchase or sell the underlying funds. For additional and more current information regarding the underlying funds, investors should read the current prospectuses and statements of additional information of the underlying funds.

Each fund will invest in some, but not all, of the underlying funds listed below. Some underlying funds may not be underlying investments for any fund, while others may serve as underlying investments for multiple funds. Each of the funds described in this prospectus relies on the professional judgment of the investment adviser to the funds and to the underlying funds to make decisions about the underlying funds' respective portfolio investments. The basic investment philosophy of the investment adviser is to seek to invest in attractively valued companies that, in its opinion, represent good, long-term investment opportunities. The investment adviser believes that an important way to accomplish this is through fundamental analysis, which may include meeting with company executives and employees, suppliers, customers and competitors. Securities may be sold when the investment adviser believes that they no longer represent relatively attractive investment opportunities.

**Underlying funds – Growth funds**

**Growth Fund** The fund's investment objective is to provide growth of capital.

The fund invests primarily in common stocks and seeks to invest in companies that appear to offer superior opportunities for growth of capital. The fund may invest up to 25% of its assets in common stocks and other securities outside the United States.

**EUPAC Fund™** The fund's investment objective is to provide you with long-term growth of capital.

The fund invests primarily in common stocks in Europe and the Pacific Basin that the investment adviser believes have the potential for growth. Growth stocks are stocks that the investment adviser believes have the potential for above-average capital appreciation.

Normally the fund will invest at least 80% of its net assets in securities of issuers in Europe and the Pacific Basin. A country will be considered part of Europe if it is part of the MSCI European indexes, and part of the Pacific Basin if any of its borders touches the Pacific Ocean. In determining the domicile of an issuer, the fund's investment adviser will generally look to the determination of MSCI Inc. (MSCI) for equity securities and Bloomberg for debt securities. In certain limited circumstances (including where relevant data is unavailable or the nature of a holding warrants special considerations), the adviser may also take into account additional factors, as applicable, including where the issuer's securities are listed; where the issuer is legally organized, maintains principal corporate offices, conducts its principal operations, generates revenues and/or has credit risk exposure; and the source of guarantees, if any, of such securities. The fund may invest a portion of its assets in common stocks and other securities of companies in emerging markets.

**Underlying funds – Growth-and-income funds**

**Growth-Income Fund** The fund's investment objectives are to achieve long-term growth of capital and income.

The fund invests primarily in common stocks or other securities that the investment adviser believes demonstrate the potential for appreciation and/or dividends. The fund may invest up to 15% of its assets outside the United States. The fund is designed for investors seeking both capital appreciation and income.

**Washington Mutual Investors Fund** The fund's investment objective is to produce income and to provide an opportunity for growth of principal consistent with sound common stock investing.

The fund invests primarily in common stocks of established companies that are listed on, or meet the financial listing requirements of, the New York Stock Exchange and have a strong record of earnings and dividends. The fund strives to accomplish its objective through fundamental research, careful selection and broad diversification. In the selection of common stocks and other securities for investment, current and potential income as well as the potential for long-term capital appreciation are considered. The fund seeks to provide an above-average yield in its quarterly income distribution in relation to the S&P 500 Index (a broad, unmanaged index). The fund strives to maintain a fully invested, diversified portfolio, consisting primarily of high-quality common stocks.

The fund has an "Eligible List" of securities considered appropriate for a prudent investor seeking opportunities for income and growth of principal consistent with common stock investing. The investment adviser generates and maintains the Eligible List and selects the fund's investments exclusively from the securities on the Eligible List.

**Underlying funds – Equity-income and balanced funds**

**Asset Allocation Fund** The fund's investment objective is to provide high total return (including income and capital gains) consistent with preservation of capital over the long term.

In seeking to pursue its investment objective, the fund varies its mix of equity securities, debt securities and money market instruments. Under normal market conditions, the fund's investment adviser expects (but is not required) to maintain an investment mix falling within the following ranges: 40%-80% in equity securities, 20%-50% in debt securities and 0%-40% in money market instruments and cash. As of December 31, 2025, the fund was approximately 65% invested in equity securities, 31% invested in debt securities and 4% invested in money market instruments and cash. The proportion of equities, debt and money market securities held by the fund varies with market conditions and the investment adviser's assessment of their relative attractiveness as investment opportunities.

The fund invests in a diversified portfolio of common stocks and other equity securities, bonds and other intermediate and long-term debt securities including U.S. government securities, and money market instruments (debt securities maturing in one year or less). The fund may invest up to 15% of its assets in common stocks and other equity securities of issuers domiciled outside the United States and up to 5% of its assets in debt securities tied economically to countries outside the United States. In addition, the fund may invest up to 25% of its debt assets in lower quality debt securities (rated Ba1 or below and BB+ or below by Nationally Recognized Statistical Rating Organizations designated by the fund's investment adviser or unrated but determined to be of equivalent quality by the fund's investment adviser). Such securities are sometimes referred to as "junk bonds."

**Underlying funds – Fixed-income funds**

**The Bond Fund of America<sup>®</sup>** The fund's investment objective is to provide as high a level of current income as is consistent with the preservation of capital.

The fund seeks to maximize your level of current income and preserve your capital by investing primarily in bonds. Normally the fund invests at least 80% of its assets in bonds and other debt securities, which may be represented by derivatives. The fund invests at least 60% of its assets in debt securities (excluding derivatives) rated A3 or better or A- or better by Nationally Recognized Statistical Ratings Organizations designated by the fund's investment adviser, or in debt securities that are unrated but determined to be of equivalent quality by the fund's investment adviser, and in U.S. government securities, money market instruments, cash or cash equivalents.

The fund may invest in debt securities and mortgage-backed securities issued by government-sponsored entities and federal agencies and instrumentalities that are not backed by the full faith and credit of the U.S. government.

The fund may invest in inflation-linked bonds issued by U.S. and non-U.S. governments, their agencies or instrumentalities, and corporations. Inflation-linked bonds are structured to protect against inflation by linking the bond's principal and interest payments to an inflation index, such as the Consumer Price Index for Urban Consumers, so that principal and interest adjust to reflect changes in the index.

The fund may invest in futures contracts and swaps, which are types of derivatives. A derivative is a financial contract, the value of which is based on the value of an underlying financial asset (such as a stock, bond or currency), a reference rate or a market index.

The fund may invest up to 5% of its assets in debt securities rated Ba1 or below and BB+ or below by Nationally Recognized Statistical Ratings Organizations designated by the fund's investment adviser, or in debt securities that are unrated but determined to be of equivalent quality by the fund's investment adviser. Securities rated Ba1 or below and BB+ or below are sometimes referred to as "junk bonds."

**U.S. Government Securities Fund<sup>®</sup>** The fund's investment objective is to provide a high level of current income consistent with prudent investment risk and preservation of capital.

Normally at least 80% of the fund's assets will be invested in securities that are guaranteed or sponsored by the U.S. government, its agencies and instrumentalities, including bonds and other debt securities denominated in U.S. dollars, which may be represented by derivatives. The fund may also invest in mortgage-backed securities issued by federal agencies and instrumentalities that are not backed by the full faith and credit of the U.S. government.

The fund may invest in inflation-linked bonds issued by U.S. and non-U.S. governments, their agencies or instrumentalities, and corporations. Inflation-linked bonds are structured to protect against inflation by linking the bond's principal and interest payments to an inflation index, such as the Consumer Price Index for Urban Consumers, so that principal and interest adjust to reflect changes in the index.

The fund may invest in futures contracts and swaps, which are types of derivatives. A derivative is a financial contract, the value of which is based on the value of an underlying financial asset (such as a stock, bond or currency), a reference rate or a market index.

**Management and organization**

**Investment adviser** Capital Research and Management Company, an experienced investment management organization founded in 1931, serves as the investment adviser to the Series and other funds, including each of the underlying funds and the American Funds. Capital Research and Management Company is a wholly owned subsidiary of The Capital Group Companies, Inc. and is located at 333 South Hope Street, Los Angeles, California 90071. The total management fee paid by each fund to its investment adviser for the most recent fiscal year, including any amounts waived, in each case expressed as a percentage of average net assets of that fund, appears in the Annual Fund Operating Expenses table for each fund. Please see the statement of additional information for further details. A discussion regarding the basis for the approval of the Series' Investment Advisory and Service Agreement by the Series' board of trustees is contained in the Series' annual or semi-annual report in Form N-CSR for the most recent fiscal period.

Capital Research and Management Company manages equity assets through three equity investment divisions and fixed income assets through its fixed income investment division, Capital Fixed Income Investors. The three equity investment divisions — Capital International Investors, Capital Research Global Investors and Capital World Investors — make investment decisions independently of one another.

The equity investment divisions may, in the future, be incorporated as wholly owned subsidiaries of Capital Research and Management Company. In that event, Capital Research and Management Company would continue to be the investment adviser, and day-to-day investment management of equity assets would continue to be carried out through one or more of these subsidiaries. Although not currently contemplated, Capital Research and Management Company could incorporate its fixed income investment division in the future and engage it to provide day-to-day investment management of fixed income assets. Capital Research and Management Company and each of the funds it advises have received an exemptive order from the U.S. Securities and Exchange Commission that allows Capital Research and Management Company to use, upon approval of the funds' boards, its management subsidiaries and affiliates to provide day-to-day investment management services to the funds, including making changes to the management subsidiaries and affiliates providing such services. The Series' shareholders approved this arrangement; however, there is no assurance that Capital Research and Management Company will incorporate its investment divisions or exercise any authority granted to it under the exemptive order.

In addition, shareholders of the Series have approved a proposal to reorganize the Series into a Delaware statutory trust. However, the Series reserved the right to delay implementing the reorganization and has elected to do so.

**Portfolio management for the funds** Capital Research and Management Company is the investment adviser to the funds and the underlying funds. The investment adviser is responsible for the management of the funds and, subject to the review and approval of the Series' board of trustees, the selection of the subadviser to the funds, the monitoring and oversight of any such subadviser and the implementation of policies and procedures reasonably designed to ensure that such subadviser complies with the funds' respective investment objectives, strategies and restrictions.

Milliman Financial Risk Management LLC is the subadviser to the funds with respect to the management of the funds' managed risk strategies.

The table below shows the investment industry experience and role in management for each of the investment adviser's investment professionals primarily responsible for management of the funds.

**The Capital System<sup>TM</sup> for the underlying funds** Capital Research and Management Company uses a system of multiple portfolio managers in managing fund assets for the underlying funds. Under this approach, the portfolio of each underlying fund is divided into segments managed by individual managers. In addition, Capital Research and Management Company's investment analysts may make investment decisions with respect to a portion of each underlying fund's portfolio. Investment decisions are subject to the underlying fund's objective(s), policies and restrictions and the oversight of the appropriate investment-related committees of Capital Research and Management Company and its investment divisions.

Certain senior members of Capital Fixed Income Investors, the investment adviser's fixed income investment division, serve on the Portfolio Strategy Group. The group utilizes a research-driven process with input from the investment adviser's analysts, portfolio managers and economists to define investment themes on a range of macroeconomic factors, including duration, yield curve and sector allocation. Where applicable, the investment decisions made by a fund's fixed income portfolio managers are informed by the investment themes discussed by the group.

**Purchases and redemptions of shares** Shares of the Series are currently offered only to insurance company separate accounts as well as so-called "feeder funds" under master-feeder arrangements sponsored by insurance companies as underlying investments for such insurance companies' variable annuity contracts and variable life insurance policies. All such shares may be purchased or redeemed by the insurance company separate accounts (or feeder funds) at net asset value without any sales or redemption charges. These purchases and redemptions are made at the price next determined after such purchases and redemptions of units of the separate accounts (or feeder funds). The Series typically expects to remit redemption proceeds one business day following receipt and acceptance of a redemption order, regardless of the method the Series uses to make such payment (e.g., check, wire or automated clearing house transfer). However, payment may take longer than one business day and may take up to seven days as generally permitted by the Investment Company Act of 1940, as amended (the "1940 Act"). Under the 1940 Act, the Series may be permitted to pay redemption proceeds beyond seven days under certain limited circumstances.

Under normal conditions, the Series typically expects to meet shareholder redemptions from a reserve of highly liquid assets, such as cash or cash equivalents. The Series may use additional methods to meet shareholder redemptions, if they become necessary. These methods may include, but are not limited to, the sale of portfolio assets, the use of overdraft protection afforded by the Series' custodian bank, borrowing from a line of credit and making payment with fund securities or other fund assets rather than in cash (as further discussed in the following paragraph).

Although payment of redemptions normally will be in cash, the Series may pay the redemption price wholly or partly with portfolio securities or other fund assets under conditions and circumstances determined by the Series' board of trustees. On the same redemption date, some shareholders may be paid in whole or in part in securities (which may differ among those shareholders), while other shareholders may be paid entirely in cash. In general, in-kind redemptions to affiliated shareholders will as closely as practicable represent the affiliated shareholder's pro rata share of the Series' securities, subject to certain exceptions. Securities distributed in-kind to unaffiliated shareholders will be selected by the investment adviser in a manner the investment adviser deems to be fair and reasonable to the Series' shareholders. The disposal of the securities received in-kind may be subject to brokerage costs and, until sold, such securities remain subject to market risk and liquidity risk, including the risk that such securities are or become difficult to sell. If the Series pays your redemption with illiquid or less liquid securities, you will bear the risk of not being able to sell such securities.

**Frequent trading of fund shares** The Series and Capital Client Group, Inc., the Series' distributor, reserve the right to reject any purchase order for any reason. The funds are not designed to serve as vehicles for frequent trading. Frequent trading of fund shares may lead to increased costs to the funds and less efficient management of the funds' portfolios, potentially resulting in dilution of the value of the shares held by long-term shareholders. Accordingly, purchases, including those that are part of exchange activity, that the Series or Capital Client Group, Inc. has determined could involve actual or potential harm to a fund may be rejected.

The Series, through its transfer agent, American Funds Service Company, has agreements with the Series' insurance relationships to maintain its surveillance procedures that are designed to detect frequent trading in fund shares. The agreements generally require the insurance companies to (i) provide, upon request from a fund, the Series or their agent, certain identifying and account information regarding contract owners who invest in fund shares through an insurance company account and (ii) execute instructions from a fund, the Series or their agent to restrict further purchases or exchanges of fund shares by a contract owner who the Series has identified as having engaged in potentially harmful market timing or frequent trading. Under these procedures, various analytics are used to evaluate factors that may be indicative of frequent trading. For example, transactions in fund shares that exceed certain monetary thresholds may be scrutinized. American Funds Service Company may work with the insurance company separate accounts or feeder funds to apply their procedures that American Funds Service Company believes are reasonably designed to enforce the frequent trading policies of the Series. You should refer to disclosures provided by the insurance company with which you have a contract to determine the specific trading restrictions that apply to you.

Under the Series' frequent trading policy, certain trading activity will not be treated as frequent trading, such as:

· retirement plan contributions, loans and distributions (including hardship withdrawals) identified as such on the retirement plan recordkeeper's system;

· purchases and redemptions in community foundation accounts;

· purchase transactions involving in-kind transfers of fund shares, if the entity maintaining the contract owner's account is able to identify the transaction as one of these types of transactions;

· transactions by certain intermediaries in accordance with established hedging programs approved by the fund's investment adviser; and

· systematic redemptions and purchases if the entity maintaining the contract owner's account is able to identify the transaction as a systematic redemption or purchase.

Generally, purchases and redemptions will not be considered "systematic" unless the transaction is prescheduled for a specific date.

American Funds Service Company will monitor for other types of activity that could potentially be harmful to the Series – for example short-term trading activity in multiple funds. If American Funds Service Company identifies any activity that may constitute frequent trading, it reserves the right to contact the insurance company separate account or feeder fund and request that the separate account or feeder fund either provide information regarding an account owner's transactions or restrict the account owner's trading. If American Funds Service Company is not satisfied that insurance company separate account or feeder fund has taken appropriate action, American Funds Service Company may terminate the separate account's or feeder fund's ability to transact in fund shares.

There is no guarantee that all instances of frequent trading in fund shares will be prevented.

**Notwithstanding the Series' surveillance procedures described above, all transactions in fund shares remain subject to the right of the Series, Capital Client Group, Inc. and American Funds Service Company to restrict potentially abusive trading generally, including the types of transactions described above that will not be prevented.**

**Valuing shares** The net asset value of each share class of each fund is calculated based in part upon the net asset value of the share class of the underlying funds in which the fund invests. The prospectus for each underlying fund explains the circumstances under which the underlying fund will use fair value pricing and the effects of using fair value pricing. The net asset value of each share class of a fund is the value of a single share of that class. Net asset value is computed by adding a class's share of the value of a fund's investments, cash and other assets, subtracting the class's share of the fund's liabilities allocated to the class, and dividing the result by the number of shares of that class that are outstanding. Realized investment income and gain is included in the fund's net asset value until the ex-dividend date, when the declared dividend amount is treated as a fund liability. The net asset value per share is calculated once daily as of the close of regular trading on the New York Stock Exchange, normally 4 p.m. New York time, each day the New York Stock Exchange is open. If the New York Stock Exchange makes a scheduled (e.g., the day after Thanksgiving) or an unscheduled close prior to 4 p.m. New York time, the net asset value of each fund will be determined at approximately the time the New York Stock Exchange closes on that day. If on such a day market quotations and prices from third-party pricing services are not based as of the time of the early close of the New York Stock Exchange but are as of a later time (up to approximately 4 p.m. New York time), for example because the market remains open after the close of the New York Stock Exchange, those later market quotations and prices will be used in determining the funds' net asset value.

Equity securities and options contracts are valued primarily on the basis of market quotations, and debt securities are valued primarily on the basis of prices from third-party pricing services due to the lack of market quotations. Futures contracts are valued primarily on the basis of settlement prices. The underlying funds' portfolio investments are valued in accordance with procedures for making fair value determinations if market quotations are not readily available, including procedures to determine the representativeness of third-party vendor prices, or in the event market quotations or third-party vendor prices are not considered reliable. For example, if events occur between the close of markets outside the United States and the close of regular trading on the New York Stock Exchange that, in the opinion of the investment adviser, materially affect the value of any of the underlying funds' equity securities that trade principally in those international markets, those securities will be valued in accordance with fair value procedures. Similarly, fair value procedures will be employed if an issuer defaults on its debt securities and there is no market for its securities. Use of these procedures is intended to result in more appropriate net asset values and, where applicable, to reduce potential arbitrage opportunities otherwise available to short-term investors.

Because the underlying funds may hold securities that are listed primarily on foreign exchanges that trade on weekends or days when the funds do not price their shares, the values of securities held in the funds may change on days when you will not be able to purchase or redeem fund shares.

Shares of the funds will be purchased or sold at the net asset value next determined after receipt of requests from the appropriate insurance company. Requests received by the appropriate insurance company prior to 4 p.m. New York time and communicated by the insurance company to the Series or its agent will be purchased or sold at that day's net asset value. Orders in good order received after the New York Stock Exchange closes (scheduled or unscheduled) will be processed at the net asset value (plus any applicable sales charge) calculated on the following business day.

**Plan of distribution** The Series has adopted a plan of distribution for Class P1 shares under which it may finance activities intended primarily to sell shares, provided that the categories of expenses are approved in advance by the Series' board of trustees. The plan provides for annual expenses of .25% for Class P1 shares; however, the Series' board of trustees has not authorized any payments under the plan.

**Other compensation to dealers** Capital Client Group, Inc., at its expense, provides additional compensation to insurance companies. These payments may be made, at the discretion of Capital Client Group, Inc., to insurance companies (or their affiliates) that have sold shares of the funds of the American Funds Insurance Series and American Funds as the exclusive underlying investments to their variable annuity contracts. A number of factors will be considered in determining payments, including the sales, assets, and the quality of the insurance company's relationship with Capital Client Group, Inc. The payment will typically be determined using a formula applied consistently to insurance companies based on the relevant facts and circumstances. Aggregate payments made by Capital Client Group, Inc. to insurance companies may also change from year to year. Only assets and deposits in variable annuity contracts that offer exclusively shares of the funds of the American Funds Insurance Series and American Funds are included in the formula. Further, assets for which the insurance company, or an affiliated broker-dealer, acts as an ERISA investment fiduciary are generally excluded from the formula. Capital Client Group, Inc. makes these payments to help defray the costs incurred by qualifying insurance companies in connection with efforts to educate their sales force about the American Funds Insurance Series and American Funds so that they help financial advisers make recommendations and provide services that are suitable and meet contractholders' needs. These payments may also be made to help defray the costs associated with the insurance company's provision of account-related services and activities and support the insurance company's distribution activities. Capital Client Group, Inc. will, on a periodic basis, determine the advisability of continuing these payments. As of May 1, 2026, the insurance companies (or their affiliates) that Capital Client Group, Inc. anticipates will receive additional compensation based on prior payments include Lincoln National Life Insurance Co.

Firms receiving additional compensation payments must sign a letter acknowledging the purpose of the payment and Capital Client Group, Inc.'s goal that the payment will help facilitate education of their sales force about the American Funds Insurance Series and American Funds to help financial professionals make suitable recommendations and better serve their clients who invest in the funds as underlying investments to variable annuity contracts. The letters generally require the firms to (1) offers shares of the funds of the American Funds Insurance Series and American Funds as the exclusive underlying investments to their variable annuity contracts, and (2) provide Capital Client Group, Inc. broad access to their sales force and product platforms and develop a business plan to achieve such access.

Capital Client Group, Inc. may also pay expenses associated with meetings and other training and educational opportunities conducted by insurance companies, selling dealers, advisory platform providers and other intermediaries to facilitate educating financial professionals and shareholders about the American Funds Insurance Series and American Funds. For example, some of these expenses may include, but not be limited to, meeting sponsor fees, meeting location fees, fees for data and reporting, and fees to obtain lists of financial professionals to better tailor training and education opportunities. In addition, Capital Client Group, Inc. and/or its affiliates may make payments to third parties for platform fees and other services.

If investment advisers, distributors or other affiliates of mutual funds pay additional compensation or other incentives to insurance companies in differing amounts, insurance companies and the financial professionals with which they interact may have financial incentives for recommending a particular mutual fund over other mutual funds or investments, creating a potential conflict of interest. You should consult with your financial professional and review carefully any disclosure by your financial professional's firm as to compensation received.

**Fund expenses** In periods of market volatility, assets of the funds and/or the applicable underlying funds may decline significantly, causing total annual fund operating expenses (as a percentage of the value of your investment) to become higher than the numbers shown in the Annual Fund Operating Expenses tables in this prospectus.

Each fund will invest in Class 1 shares of the applicable underlying fund(s). Accordingly, fees and expenses of the underlying fund(s) reflect current expenses of the Class 1 shares of the underlying fund(s). The "Other expenses" items in the Annual Fund Operating Expenses tables in this prospectus are based on expenses as of each fund's most recently completed fiscal year. These items include third-party expenses, such as custodial, legal, audit, accounting, regulatory reporting and pricing vendor services, and an administrative services fee provided by the insurance companies that include the funds as an underlying investment in their variable contracts. Each fund will pay an insurance administration fee of .25% to these insurance companies for providing certain services pursuant to an insurance administrative services plan adopted by the Series.

**Investment results** All fund results in the "Investment results" section of this prospectus reflect the reinvestment of dividends and capital gains distributions, if any. Unless otherwise noted, fund results reflect any fee waivers and/or expense reimbursements in effect during the period presented.

**Distributions and taxes** Each fund of the Series intends to qualify as a "regulated investment company" under the Internal Revenue Code. In any fiscal year in which a fund so qualifies and distributes to shareholders its investment company taxable income and net realized capital gain, the fund itself is relieved of federal income tax.

It is the Series' policy to distribute to the shareholders (the insurance company separate accounts) all of its investment company taxable income and capital gain for each fiscal year.

#### See the applicable contract prospectus for information regarding the federal income tax treatment of the contracts and distributions to the separate accounts.

**Financial highlights** The Financial Highlights table is intended to help you understand a fund's results for the past five fiscal years (or, if shorter, the period of operations). Certain information reflects financial results for a single share of a particular class. The total returns in the table represent the rate that an investor would have earned or lost on an investment in a fund (assuming reinvestment of all dividends and capital gain distributions). Where indicated, figures in the table reflect the impact, if any, of certain waivers/reimbursements from Capital Research and Management Company. For more information about these waivers/reimbursements, see the fund's statement of additional information and Form N-CSR. The information in the Financial Highlights table has been audited by PricewaterhouseCoopers LLP, whose current report, along with the funds' financial statements, is included in the statement of additional information, which is available upon request. Figures shown do not reflect insurance contract fees and expenses. If insurance contract fees and expenses were reflected, results would be lower.

 **Managed Risk EUPAC Fund** 

**Investment objective** The fund's investment objective is to provide you with long-term growth of capital while seeking to manage volatility and provide downside protection.

**Fees and expenses of the fund** This table describes the fees and expenses that you may pay if you buy, hold and sell an interest in Class P2 shares of the fund. **You may pay other fees, such as insurance contract fees and expenses, which are not reflected in the tables and examples below.** If insurance contract fees and expenses were reflected, expenses shown would be higher.

| Other expenses | 0.31 |
| Acquired (underlying) fund fees and expenses<sup>1</sup> | 0.43 |
| Total annual fund operating expenses | 1.09 |
| Expense reimbursement<sup>2</sup> | 0.03 |
| Total annual fund operating expenses after expense reimbursement | 1.06 |

<sup>1</sup> Restated to reflect current fees.

<sup>2</sup>The investment adviser is currently reimbursing a portion of the other expenses. This reimbursement will be in effect through at least May 1, 2027. The adviser may elect at its discretion to extend, modify or terminate the reimbursement at that time.

**Example** This example is intended to help you compare the cost of investing in Class P2 shares of the fund with the cost of investing in other mutual funds.

The example assumes that you invest $10,000 in the fund for the time periods indicated and then redeem or hold all of your shares at the end of those periods. The example also assumes that your investment has a 5% return each year and that the fund's operating expenses remain the same. The example does not reflect insurance contract expenses. If insurance contract expenses were reflected, expenses shown would be higher. The example reflects the expense reimbursement described above through the expiration date of such reimbursement and total annual fund operating expenses thereafter. No sales charge (load) or other fees are charged by the fund upon redemption, so you would incur these hypothetical costs whether or not you were to redeem your shares at the end of the given period. Although your actual costs may be higher or lower, based on these assumptions your costs would be:

|:---|:---|:---|:---|:---|
|  | 1 year | 3 years | 5 years | 10 years |
| Class P2 | $108 | $344 | $598 | $1326 |

---

**Portfolio turnover** The fund pays transaction costs, such as commissions, when it buys and sells securities and other instruments (or "turns over" its portfolio). A higher portfolio turnover rate may indicate higher transaction costs. These costs, which are not reflected in annual fund operating expenses or in the example, affect the fund's investment results. During the most recent fiscal year, the fund's portfolio turnover rate was 17% of the average value of its portfolio.

**Principal investment strategies** The fund pursues its investment objective by investing in shares of two underlying funds, the American Funds Insurance Series – EUPAC Fund (the "EUPAC Fund") and the American Funds Insurance Series – The Bond Fund of America ("The Bond Fund of America") – while seeking to manage portfolio volatility and provide downside protection primarily through the use of exchange-traded options and futures contracts.

The fund normally seeks to invest 85% of its assets in the EUPAC Fund, the investment objective of which is to provide long-term growth of capital. The EUPAC Fund invests primarily in common stocks in Europe and the Pacific Basin that the investment adviser believes have the potential for growth. Growth stocks are stocks that the investment adviser believes have the potential for above average capital appreciation. The fund invests the remainder of its assets in The Bond Fund of America and in cash, financial futures and options as part of the managed risk strategy. The Bond Fund of America's investment objective is to provide as high a level of current income as is consistent with the preservation of capital. The Bond Fund of America seeks to maximize your level of current income and preserve your capital by investing primarily in bonds. Normally, The Bond Fund of America invests at least 80% of its assets in bonds and other debt securities, which may be represented by derivatives. The Bond Fund of America invests at least 60% of its assets in debt securities (excluding derivatives) rated A3 or better or A- or better by Nationally Recognized Statistical Ratings Organizations designated by the fund's investment adviser, or in debt securities that are unrated but determined to be of equivalent quality by the fund's investment adviser and in U.S. government securities, money market instruments, cash or cash equivalents.

The fund's investment in The Bond Fund of America seeks to provide a level of diversification across asset classes. Because different asset classes often react differently to changes in market conditions, such diversification seeks to manage the fund's risk to market changes, including stock market declines. Additionally, the fund employs a risk-management overlay referred to in this prospectus as the managed risk strategy. The managed risk strategy consists of using hedge instruments — primarily exchange-traded futures contracts and/or exchange-traded put options — to attempt to stabilize the volatility of the fund around a target volatility level and to seek to reduce the downside exposure of the fund. The fund employs a subadviser to select individual put options and futures contracts on equity indexes of U.S. markets and markets outside the United States that the subadviser believes are correlated to the underlying fund's equity exposure. These instruments are selected based on the subadviser's analysis of the relation of various equity indexes to the underlying fund's portfolio. In addition, the subadviser will monitor liquidity levels of relevant options and futures contracts and transparency provided by exchanges as the counterparties in hedging transactions. The target volatility level will be set from time to time by the investment adviser and the subadviser and may be adjusted if deemed advisable in the judgment of the investment adviser and the subadviser. The

------

subadviser may also seek to hedge the fund's currency risk related to its exposure to equity index options and futures denominated in currencies other than the U.S. dollar.

A futures contract on an index is an agreement pursuant to which two parties agree to take or make delivery of an amount of cash linked to the value of the index at the close of the last trading day of the contract. Though similar, an option on an index gives one party the contractual right (but not the obligation) to take or make delivery of an amount of cash linked to the value of the underlying index. Because such instruments derive their respective values from the price of an underlying index, both options and futures contracts are considered derivatives. A long position in an equity index put option and a short position in an equity index futures contract are both expected to gain in value when the underlying index declines, and lose value when the underlying index rises.

The subadviser regularly adjusts the level of exchange-traded options and futures contracts held by the fund to seek to manage the fund's overall net risk level. In situations of extreme market volatility, the subadviser will tend to use exchange-traded equity index options and/or futures more heavily, as such investments could significantly reduce the fund's net economic exposure to equity securities. Even in periods of low volatility in the equity markets, however, the subadviser will continue to employ exchange-traded equity index put options to seek to preserve gains after favorable market conditions and to reduce losses in adverse market conditions. During such periods of low equity market volatility, the subadviser may also continue to use exchange-traded equity index futures contracts for hedging purposes, though it need not necessarily do so. In certain market conditions, the fund may also purchase exchange-traded equity index call options, write or sell exchange-traded equity index put and call options and/or take net long positions in exchange-traded equity index futures contracts.

Prior to May 1, 2026, the fund was called Managed Risk International Fund.

**Principal risks This section describes the principal risks associated with investing in the fund. You may lose money by investing in the fund. The likelihood of loss may be greater if you invest for a shorter period of time. Investors in the fund should also understand that the fund's objective of protecting against downside losses may result in the fund not realizing the full gains of the underlying funds. In addition, the managed risk strategy may not effectively protect the fund from market declines.** 

*Fund structure* — The fund invests in underlying funds and incurs expenses related to those underlying funds. In addition, investors in the fund will incur fees to pay for certain expenses related to the operations of the fund. An investor holding the underlying funds directly would incur lower overall expenses but would not receive the benefit of the managed risk strategy. Additionally, in accordance with an exemption under the Investment Company Act of 1940, as amended, the investment adviser considers only proprietary funds when selecting underlying investment options and allocations. This means that the fund's investment adviser does not, nor does it expect to, consider any unaffiliated funds as underlying investment options for the fund. This strategy could raise certain conflicts of interest when determining the overall asset allocation of the fund or choosing underlying investments for the fund, including the selection of funds that result in greater compensation to the adviser or funds with relatively lower historical investment results. The investment adviser has policies and procedures designed to mitigate material conflicts of interest that may arise in connection with its management of the fund.

*Underlying fund risks* — Because the fund's investments consist of investments in underlying funds, the fund's risks are directly related to the risks of those underlying funds. For this reason, it is important to understand the risks associated with investing both in the fund and in each of the underlying funds.

*Investing in derivatives* — The use of derivatives involves a variety of risks, which may be different from, or greater than, the risks associated with investing in traditional securities, such as stocks and bonds. Changes in the value of a derivative may not correlate perfectly with, and may be more sensitive to market events than, the underlying asset, rate or index, and a derivative instrument may cause the fund or an underlying fund to lose significantly more than its initial investment. Derivatives may be difficult to value, difficult for the fund or an underlying fund to buy or sell at an opportune time or price and difficult, or even impossible, to terminate or otherwise offset. A fund's use of derivatives may result in losses to the fund, and investing in derivatives may reduce the fund's returns and increase the fund's price volatility. A fund's counterparty to a derivative transaction (including, if applicable, the fund's clearing broker, the derivatives exchange or the clearinghouse) may be unable or unwilling to honor its financial obligations in respect of the transaction. In certain cases, the fund or an underlying fund may be hindered or delayed in exercising remedies against or closing out derivative instruments with a counterparty, which may result in additional losses. Derivatives are also subject to operational risk (such as documentation issues, settlement issues and systems failures) and legal risk (such as insufficient documentation, insufficient capacity or authority of a counterparty, and issues with the legality or enforceability of a contract).

*Investing in options and futures contracts* — In addition to the risks generally associated with investing in derivative instruments, options and futures contracts are subject to the creditworthiness of the clearing organizations, exchanges and, in the case of futures, futures commission merchants with which the fund transacts. While both options and futures contracts are generally liquid instruments, under certain market conditions, options and futures may be deemed to be illiquid. For example, the fund may be temporarily prohibited from closing out its position in an options or futures contract if intraday price change limits or limits on trading volume imposed by the applicable exchange are triggered. If the fund is unable to close out a position on an options or futures contract, the fund would remain subject to the risk of adverse price movements until the fund is able to close out the position in question. The ability of the fund to successfully utilize options and futures contracts may depend in part upon the ability of the fund's investment adviser or subadviser to accurately forecast interest rates and other economic factors and to assess and predict the impact of such economic factors on the options and futures in which the fund invests. If the investment adviser or subadviser incorrectly forecasts economic developments or incorrectly predicts the impact of such developments on the options and futures in which it invests, the fund could suffer losses. Whereas the risk of loss on a put option purchased by the fund is limited to the initial cost of the option, the amount of a potential loss on a futures contract could greatly exceed the relatively small initial amount invested in entering the futures position.

*Hedging* — There may be imperfect or even negative correlation between the prices of the options and futures contracts in which the fund invests and the prices of the underlying securities or indexes which the fund seeks to hedge. For example, options and futures contracts may not provide an effective hedge because changes in options and futures contract prices may not track those of the underlying

American Funds Insurance Series — Managed Risk Funds / Prospectus&nbsp;&nbsp;&nbsp;&nbsp; 2

------

securities or indexes they are intended to hedge. In addition, there are significant differences between the securities market, on the one hand, and the options and futures markets, on the other, that could result in an imperfect correlation between the markets, causing a given hedge not to achieve its objectives. The degree of imperfection of correlation depends on circumstances such as variations in speculative market demand for options and futures, including technical influences in options and futures trading, and differences between the financial instruments being hedged and the instruments underlying the standard contracts available for trading. A decision as to whether, when and how to hedge involves the exercise of skill and judgment, and even a well-conceived hedge may be unsuccessful to some degree because of market behavior or unexpected interest rate trends. In addition, the fund's investment in exchange-traded options and futures and their resulting costs could limit the fund's gains in rising markets relative to those of the underlying funds, or to those of unhedged funds in general.

*Short positions* — The fund may suffer losses from short positions in futures contracts. Losses from short positions in futures contracts occur when the underlying index increases in value. As the underlying index increases in value, the holder of the short position in the corresponding futures contract is required to pay the difference in value of the futures contract resulting from the increase in the index on a daily basis. Losses from a short position in an index futures contract could potentially be very large if the value of the underlying index rises dramatically in a short period of time.

*Market conditions* — The prices of, and the income generated by, the securities held by an underlying fund may decline – sometimes rapidly or unpredictably – due to various factors, including events or conditions affecting the general economy or particular industries or companies; overall market changes; local, regional or global political, social or economic instability; governmental, governmental agency or central bank responses to economic conditions; levels of public debt and deficits; changes in inflation rates; and currency exchange rate, interest rate and commodity price fluctuations.

Economies and financial markets throughout the world are highly interconnected. Economic, financial or political events, trading and tariff arrangements, wars, terrorism, cybersecurity events, natural disasters, public health emergencies (such as the spread of infectious disease), bank failures and other circumstances in one country or region, including actions taken by governmental or quasi-governmental authorities in response to any of the foregoing, could have impacts on global economies or markets. As a result, whether or not an underlying fund invests in securities of issuers located in or with significant exposure to the countries affected, the value and liquidity of an underlying fund's investments may be negatively affected by developments in other countries and regions.

*Issuer risks* — The prices of, and the income generated by, securities held by an underlying fund may decline in response to various factors directly related to the issuers of such securities, including reduced demand for an issuer's goods or services, poor management performance, major litigation, investigations or other controversies related to the issuer, changes in the issuer's financial condition or credit rating, changes in government regulations affecting the issuer or its competitive environment and strategic initiatives such as mergers, acquisitions or dispositions and the market response to any such initiatives. An individual security may also be affected by factors relating to the industry or sector of the issuer or the securities markets as a whole, and conversely an industry or sector or the securities markets may be affected by a change in financial condition or other event affecting a single issuer.

*Investing in growth-oriented stocks* — Growth-oriented common stocks and other equity-type securities (such as preferred stocks, convertible preferred stocks and convertible bonds) may involve larger price swings and greater potential for loss than other types of investments. These risks may be even greater in the case of smaller capitalization stocks.

*Investing outside the United States* — Securities of issuers domiciled outside the United States or with significant operations or revenues outside the United States, and securities tied economically to countries outside the United States, may lose value because of adverse political, social, economic or market developments (including social instability, regional conflicts, terrorism and war) in the countries or regions in which the issuers are domiciled, operate or generate revenue or to which the securities are tied economically. These securities may also lose value due to changes in foreign currency exchange rates against the U.S. dollar and/or currencies of other countries. Issuers of these securities may be more susceptible to actions of foreign governments, such as nationalization, currency blockage or the imposition of price controls, sanctions, or punitive taxes, each of which could adversely impact the value of these securities. Securities markets in certain countries may be more volatile and/or less liquid than those in the United States. Investments outside the United States may also be subject to different regulatory, legal, accounting, auditing, financial reporting and recordkeeping requirements, and may be more difficult to value, than those in the United States. In addition, the value of investments outside the United States may be reduced by foreign taxes, including foreign withholding taxes on interest and dividends. Further, there may be increased risks of delayed settlement of securities purchased or sold by an underlying fund, which could impact the liquidity of the fund's portfolio. The risks of investing outside the United States may be heightened in connection with investments in emerging markets.

*Investing in emerging markets* — Investing in emerging markets may involve risks in addition to and greater than those generally associated with investing in the securities markets of developed countries. For instance, emerging market countries tend to have less developed political, economic and legal systems than those in developed countries. Accordingly, the governments of these countries may be less stable and more likely to intervene in the market economy, for example, by imposing capital controls, nationalizing a company or industry, placing restrictions on foreign ownership and on withdrawing sale proceeds of securities from the country, and/or imposing punitive taxes that could adversely affect the prices of securities. Information regarding issuers in emerging markets may be limited, incomplete or inaccurate, and such issuers may not be subject to regulatory, accounting, auditing, and financial reporting and recordkeeping standards comparable to those to which issuers in more developed markets are subject. The underlying fund's rights with respect to its investments in emerging markets, if any, will generally be governed by local law, which may make it difficult or impossible for the underlying fund to pursue legal remedies or to obtain and enforce judgments in local courts. In addition, the economies of these countries may be dependent on relatively few industries, may have limited access to capital and may be more susceptible to changes in local and global trade conditions and downturns in the world economy. Securities markets in these countries can also be relatively small and have substantially lower trading volumes. As a result, securities issued in these countries may be more volatile and less liquid, more vulnerable

------

to market manipulation, and more difficult to value, than securities issued in countries with more developed economies and/or markets. Less certainty with respect to security valuations may lead to additional challenges and risks in calculating the underlying fund's net asset value. Additionally, emerging markets are more likely to experience problems with the clearing and settling of trades and the holding of securities by banks, agents and depositories that are less established than those in developed countries.

*Investing in debt instruments* — The prices of, and the income generated by, bonds and other debt securities held by an underlying fund may be affected by factors such as the interest rates, maturities and credit quality of these securities.

Rising interest rates will generally cause the prices of bonds and other debt securities to fall. Also, when interest rates rise, issuers of debt securities that may be prepaid at any time, such as mortgage- or other asset-backed securities, are less likely to refinance existing debt securities, causing the average life of such securities to extend. A general change in interest rates may cause investors to sell debt securities on a large scale, which could also adversely affect the price and liquidity of debt securities and could also result in increased redemptions from the fund. Falling interest rates may cause an issuer to redeem, call or refinance a debt security before its stated maturity, which may result in the fund having to reinvest the proceeds in lower yielding securities. Longer maturity debt securities generally have greater sensitivity to changes in interest rates and may be subject to greater price fluctuations than shorter maturity debt securities.

Bonds and other debt securities are also subject to credit risk, which is the possibility that the credit strength of an issuer or guarantor will weaken or be perceived to be weaker, and/or an issuer of a debt security will fail to make timely payments of principal or interest and the security will go into default. Changes in actual or perceived creditworthiness may occur quickly. A downgrade or default affecting any of the fund's securities could cause the value of the fund's shares to decrease. Lower quality debt securities generally have higher rates of interest and may be subject to greater price fluctuations than higher quality debt securities. Credit risk is gauged, in part, by the credit ratings of the debt securities in which an underlying fund invests. However, ratings are only the opinions of the rating agencies issuing them and are not guarantees as to credit quality or an evaluation of market risk. The fund's investment adviser relies on its own credit analysts to research issuers and issues in assessing credit and default risks.

*Management* — The investment adviser to the fund and to the underlying funds actively manages each underlying fund's investments. Consequently, each underlying fund is subject to the risk that the methods and analyses, including models, tools and data, employed by the investment adviser in this process may be flawed or incorrect and may not produce the desired results. In addition, the fund is subject to the risk that the managed risk strategy or the methods employed by the subadviser in implementing the managed risk strategy may not produce the desired results. The occurrence of either or both of these events could cause the fund to lose value or its investment results to lag relevant benchmarks or other funds with similar objectives.

Your investment in the fund is not a bank deposit and is not insured or guaranteed by the Federal Deposit Insurance Corporation or any other governmental agency, entity or person. You should consider how this fund fits into your overall investment program.

**Purchase and sale of fund shares** Shares of the fund are not sold directly to the general public. The fund is offered only as an underlying investment option for variable insurance contracts, and insurance company separate accounts and qualified feeder funds — and not the holders of variable insurance contracts — are the shareholders of the fund. Although the fund does not require a minimum amount for initial or subsequent purchases from insurance companies, your insurance company may impose investment minimums for your purchase of the fund.

You may sell (redeem) shares on any business day. You must sell (redeem) shares through your insurance company.

**Tax information** See your variable insurance contract prospectus for information regarding the federal income tax treatment of your variable insurance contract and related distributions.

**Payments to broker-dealers and other financial intermediaries** The fund is not sold directly to the general public but instead is offered as an underlying investment option for variable insurance contracts. The fund and its related companies may make payments to the sponsoring insurance company (or its affiliates) for distribution and/or other services. These payments may be a factor that the insurance company considers in including the fund as an underlying investment option in the variable insurance contract. The prospectus (or other offering document) for your variable insurance contract may contain additional information about these payments.

**Investment objectives, strategies and risks** 

**Managed Risk EUPAC Fund** The fund's investment objective is to provide you with long-term growth of capital while seeking to manage volatility and provide downside protection. While it has no present intention to do so, the fund's board may change the fund's investment objective without shareholder approval upon 60 days' prior written notice to shareholders. The fund pursues its investment objective by investing in Class 1 shares of the American Funds Insurance Series – EUPAC Fund (the "EUPAC Fund") and the American Funds Insurance Series – The Bond Fund of America ("The Bond Fund of America"), while seeking to manage portfolio volatility and risk of loss primarily through the use of exchange-traded options and futures contracts.

The fund normally seeks to invest 85% of its assets in the EUPAC Fund. The investment objective of the EUPAC Fund is to provide long-term growth of capital. The EUPAC Fund invests primarily in common stocks in Europe and the Pacific Basin that the investment adviser believes have the potential for growth. Growth stocks are stocks that the underlying fund's investment adviser believes have the potential for above average capital appreciation.

Normally, the EUPAC Fund will invest at least 80% of its net assets in securities of issuers in Europe and the Pacific Basin. A country will be considered part of Europe if it is part of the MSCI European indexes, and part of the Pacific Basin if any of its borders touches the Pacific Ocean. In determining the domicile of an issuer, the underlying fund's investment adviser will generally look to the determination of MSCI Inc. (MSCI) for equity securities and Bloomberg for debt securities. In certain limited circumstances (including where relevant data is unavailable or the nature of a holding warrants special considerations), the adviser may also take into account additional factors, as applicable, including where the issuer's securities are listed; where the issuer is legally organized, maintains principal corporate offices, conducts its principal operations, generates revenues and/or has credit risk exposure; and the source of guarantees, if any, of such securities. The fund may invest a portion of its assets in common stocks and other securities of companies in emerging markets.

The fund invests the remainder of its assets in The Bond Fund of America and in cash, financial futures and options as part of the managed risk strategy. The investment objective of The Bond Fund of America is to provide as high a level of current income as is consistent with the preservation of capital. The Bond Fund of America seeks to maximize your level of current income and preserve your capital by investing primarily in bonds. Normally, The Bond Fund of America invests at least 80% of its assets in bonds and other debt securities, which may be represented by derivatives. The Bond Fund of America invests at least 60% of its assets in debt securities (excluding derivatives) rated A3 or better or A- or better by Nationally Recognized Statistical Rating Organizations, or NRSROs, designated by the underlying fund's investment adviser or in debt securities that are unrated but determined to be of equivalent quality by the fund's investment adviser, and in U.S. government securities, money market instruments, cash or cash equivalents.

The Bond Fund of America may invest, subject to the restrictions above, in contracts for future delivery of mortgage-backed securities, such as to-be-announced contracts and mortgage rolls. Although The Bond Fund of America may generally invest in debt securities of any maturity or duration, such contracts are normally of short duration and may be replaced by another contract prior to maturity. Each such transaction is reflected as turnover in The Bond Fund of America's portfolio, resulting in a higher portfolio turnover rate than funds that do not employ this investment strategy.

The Bond Fund of America may invest in debt securities and mortgage-backed securities issued by government-sponsored entities and federal agencies and instrumentalities that are not backed by the full faith and credit of the U.S. government. The Bond Fund of America may invest in debt securities of any maturity or duration. Duration is a measure used to determine the sensitivity of a security's price to changes in interest rates. The longer a security's duration, the more sensitive it will be to changes in interest rates.

The Bond Fund of America may invest in inflation-linked bonds issued by U.S. and non-U.S. governments, their agencies or instrumentalities and corporations. Inflation-linked bonds are structured to protect against inflation by linking the bond's principal and interest payments to an inflation index, such as the Consumer Price Index for Urban Consumers, so that principal and interest adjust or reflect changes in the index.

The Bond Fund of America may invest in futures contracts and swaps, which are types of derivatives. A derivative is a financial contract, the value of which is based on the value of an underlying financial asset (such as a stock, bond or currency), a reference rate or a market index.

The Bond Fund of America may invest in futures contracts and interest rate swaps in order to seek to manage The Bond Fund of America's sensitivity to interest rates, and in credit default swap indices, or CDSIs, in order to assume exposure to a diversified portfolio of credits or to hedge against existing credit risks. A futures contract is a standardized exchange-traded agreement to buy or sell a specific quantity of an underlying asset, rate or index at an agreed-upon price at a stipulated future date. An interest rate swap is an agreement between two parties to exchange or swap payments based on changes in one or more interest rates, one of which is typically fixed and the other of which is typically a floating rate based on a designated short-term interest rate, such as the Secured Overnight Financing Rate, prime rate or other benchmark. A CDSI is based on a portfolio of credit default swaps with similar characteristics, such as credit default swaps on high-yield bonds. In a typical CDSI transaction, one party – the protection buyer – is obligated to pay the other party – the protection seller – a stream of periodic payments over the term of the contract, provided generally that no credit event on an underlying reference obligation has occurred. If such a credit event has occurred, the protection seller must pay the protection buyer the loss on those credits.

The Bond Fund of America may also enter into currency transactions to provide for the purchase or sale of a currency needed to purchase a security denominated in that currency. In addition, The Bond Fund of America may enter into forward currency contracts to protect against changes in currency exchange rates. The Bond Fund of America may also enter into forward currency contracts to seek to increase total return. A forward currency contract is an agreement to purchase or sell a specific currency at a future date at a fixed price.

The Bond Fund of America may invest up to 5% of its assets in debt securities rated Ba1 or below and BB+ or below by NRSROs designated by the underlying fund's investment adviser, or in debt securities that are unrated but determined to be of equivalent quality by the underlying fund's investment adviser. Such securities are sometimes referred to as "junk bonds."

The fund's investment in The Bond Fund of America seeks to provide a level of diversification across asset classes. Because different asset classes often react differently to changes in market conditions, such diversification seeks to manage the fund's risk to market changes, including stock market declines. Additionally, the fund employs a risk-management overlay or managed risk strategy. The managed risk strategy consists of using hedge instruments — primarily exchange-traded futures contracts and/or exchange-traded put options — to attempt to stabilize the volatility of the fund around a target volatility level and to seek to reduce the downside exposure of the fund. "Volatility" in this context means variance in the fund's investment results. The fund employs a subadviser to select individual put options and futures contracts on equity indexes of U.S. markets and markets outside the United States that the subadviser believes are correlated to the underlying fund's equity exposure. These instruments are selected based on the subadviser's analysis of the relation of various equity indexes to the underlying fund's portfolio. In addition, the subadviser will monitor liquidity levels of relevant options and futures contracts and transparency provided by exchanges as the counterparties in hedging transactions. The target volatility level will be set from time to time by the investment adviser and the subadviser and may be adjusted if deemed advisable in the judgment of the investment adviser and the subadviser. The subadviser will regularly adjust the level of exchange-traded futures contracts to seek to manage the overall net risk level of the fund. The subadviser may also seek to hedge the fund's currency risk related to its exposure to equity index options and futures denominated in currencies other than the U.S. dollar.

Prior to May 1, 2026, the fund was called Managed Risk International Fund.

The subadviser regularly adjusts the level of exchange-traded options and futures contracts held by the fund to seek to manage the fund's overall net risk level. During periods of generally rising equity security prices, the subadviser will normally increase the target level of protection in the fund to seek to protect the growing value of the fund's portfolio. During or after severe market downturns, however, the fund's subadviser is expected to realize gains for the fund on the fund's put options and short futures positions and the amount of options and futures held by the fund will likely decrease. Even in periods of low volatility in the equity markets, the subadviser will continue to employ exchange-traded equity index put options to seek to preserve gains in favorable market conditions and to reduce losses in adverse market conditions. During such periods of low equity market volatility, the subadviser may also continue to use exchange-traded equity index futures contracts for hedging purposes, though it need not necessarily do so. In the event of a sudden market dislocation, the managed risk strategy may not provide the same downside protection as in other periods. Accordingly, in certain market conditions, the fund may also purchase exchange-traded equity index call options, write (or sell) exchange-traded equity index put and call options and/or take net long positions in exchange-traded equity index futures contracts. In addition, under certain market conditions (including during periods of low equity market volatility, when the subadviser may employ exchange-traded equity index futures to a lesser degree or not at all), the subadviser reserves the right to purchase or sell exchange-traded interest rate futures, including futures contracts on U.S. Treasury bonds, to seek to manage interest rate risk.

From time to time, including during severe market dislocations, the fund may adjust its managed risk strategy if advisable in the judgment of the fund's investment adviser and subadviser. For example, if the market for swaps moves, as is expected, from a largely over-the-counter market to an exchange-traded market as a result of recent regulatory changes, the subadviser may use exchange-traded swaps to seek to hedge interest rate risk if the fund's investment adviser and subadviser determine that the exchange-traded swaps market has become similar in depth and substance to that of the exchange-traded options and futures markets. Before adjusting the fund's managed risk strategy, the fund's investment adviser and subadviser may consult with insurance companies that offer the fund as an underlying investment option for variable contracts; provided, however that any adjustment will be made in the judgment of the investment adviser and the subadviser. Any such adjustment may not have the desired positive effect, and could potentially have further adverse effects, on the fund's investment results.

The subadviser will purchase or sell futures contracts through a futures commission merchant, or FCM. The fund may be required to own cash or other liquid assets, including U.S. Treasury securities, and post these assets with an FCM or broker as collateral to cover the fund's obligations under its futures contracts. Upon entering into a futures contract, for example, the fund will be required to deposit with the FCM an amount of cash (or other liquid assets, including U.S. Treasury securities) for collateral, or initial margin, that will be held at the clearinghouse or exchange in the name of the FCM. On a daily basis, the fund will be required to post additional cash with the FCM if a futures contract loses value or will receive cash if a futures contract gains in value. This cash, known as variation margin, may be held intraday at the FCM. Cash received by the fund may be invested in U.S. Treasury futures.

The fund or an underlying fund may also hold cash or cash equivalents, including commercial paper and short-term securities issued by the U.S. government, its agencies and instrumentalities. The fund may also hold money market fund shares as part of its cash position. The percentage of the fund or an underlying fund invested in such holdings varies and depends on various factors, including market conditions and purchases and redemptions of fund shares. The investment adviser may determine that it is appropriate to invest a substantial portion of the fund's assets in such instruments in response to certain circumstances, such as periods of market turmoil. For temporary defensive purposes, the fund or an underlying fund may invest without limitation in such instruments. A larger percentage of such holdings could moderate a fund's investment results in a period of rising market prices. Alternatively, a larger percentage of such holdings could reduce the magnitude of a fund's loss in a period of falling market prices and provide liquidity to make additional investments or to meet redemptions.

An underlying fund may invest in certain other funds managed by the investment adviser or its affiliates ("Central Funds") to more effectively invest in a diversified set of securities in a specific asset class such as money market instruments, bonds and other securities. Shares of Central Funds are only offered for purchase to the fund's investment adviser and its affiliates and other funds, investment vehicles and accounts managed by the fund's investment adviser and its affiliates. Central Funds do not charge management fees. As a result, an underlying fund does not bear additional management fees when investing in Central Funds, but an underlying fund does bear its proportionate share of Central Fund expenses. The investment results of the portions of an underlying fund's assets invested in the Central Funds will be based upon the investment results of the Central Funds.

The investment adviser may consider environmental, social and governance ("ESG") factors that, depending on the facts and circumstances, are material to the value of an issuer or instrument. ESG factors may include, but are not limited to, environmental issues (e.g., water use, emission levels, waste, environmental remediation), social issues (e.g., human capital, health and safety, changing customer behavior) or governance issues (e.g., board composition, executive compensation, shareholder dilution).

The following are principal risks associated with investing in the fund.

*Fund structure* — The fund invests in underlying funds and incurs expenses related to those underlying funds. In addition, investors in the fund will incur fees to pay for certain expenses related to the operations of the fund. An investor holding the underlying funds directly would incur lower overall expenses but would not receive the benefit of the managed risk strategy. Additionally, in accordance with an exemption under the Investment Company Act of 1940, as amended, the investment adviser considers only proprietary funds when selecting underlying investment options and allocations. This means that the fund's investment adviser does not, nor does it expect to, consider any unaffiliated funds as underlying investment options for the fund. This strategy could raise certain conflicts of interest when determining the overall asset allocation of the fund or choosing underlying investments for the fund, including the selection of funds that result in greater compensation to the adviser or funds with relatively lower historical investment results. The investment adviser has policies and procedures designed to mitigate material conflicts of interest that may arise in connection with its management of the fund.

*Underlying fund risks* — Because the fund's investments consist of investments in underlying funds, the fund's risks are directly related to the risks of those underlying funds. For this reason, it is important to understand the risks associated with investing both in the fund and in each of the underlying funds.

*Investing in derivatives* — The use of derivatives involves a variety of risks, which may be different from, or greater than, the risks associated with investing in traditional securities, such as stocks and bonds. Changes in the value of a derivative may not correlate perfectly with, and may be more sensitive to market events than, the underlying asset, rate or index, and a derivative instrument may cause the fund or an underlying fund to lose significantly more than its initial investment. Derivatives may be difficult to value, difficult for the fund or an underlying fund to buy or sell at an opportune time or price and difficult, or even impossible, to terminate or otherwise offset. A fund's use of derivatives may result in losses to the fund, and investing in derivatives may reduce the fund's returns and increase the fund's price volatility. A fund's counterparty to a derivative transaction (including, if applicable, the fund's clearing broker, the derivatives exchange or the clearinghouse) may be unable or unwilling to honor its financial obligations in respect of the transaction. In certain cases, the fund or an underlying fund may be hindered or delayed in exercising remedies against or closing out derivative instruments with a counterparty, which may result in additional losses. Derivatives are also subject to operational risk (such as documentation issues, settlement issues and systems failures) and legal risk (such as insufficient documentation, insufficient capacity or authority of a counterparty, and issues with the legality or enforceability of a contract).

*Investing in options and futures contracts* — In addition to the risks generally associated with investing in derivative instruments, options and futures contracts are subject to the creditworthiness of the clearing organizations, exchanges and, in the case of futures, futures commission merchants with which the fund transacts. While both options and futures contracts are generally liquid instruments, under certain market conditions, options and futures may be deemed to be illiquid. For example, the fund may be temporarily prohibited from closing out its position in an options or futures contract if intraday price change limits or limits on trading volume imposed by the applicable exchange are triggered. If the fund is unable to close out a position on an options or futures contract, the fund would remain subject to the risk of adverse price movements until the fund is able to close out the position in question. The ability of the fund to successfully utilize options and futures contracts may depend in part upon the ability of the fund's investment adviser or subadviser to accurately forecast interest rates and other economic factors and to assess and predict the impact of such economic factors on the options and futures in which the fund invests. If the investment adviser or subadviser incorrectly forecasts economic developments or incorrectly predicts the impact of such developments on the options and futures in which it invests, the fund could suffer losses. Whereas the risk of loss on a put option purchased by the fund is limited to the initial cost of the option, the amount of a potential loss on a futures contract could greatly exceed the relatively small initial amount invested in entering the futures position.

*Hedging* — There may be imperfect or even negative correlation between the prices of the options and futures contracts in which the fund invests and the prices of the underlying securities or indexes which the fund seeks to hedge. For example, options and futures contracts may not provide an effective hedge because changes in options and futures contract prices may not track those of the underlying securities or indexes they are intended to hedge. In addition, there are significant differences between the securities market, on the one hand, and the options and futures markets, on the other, that could result in an imperfect correlation between the markets, causing a given hedge not to achieve its objectives. The degree of imperfection of correlation depends on circumstances such as variations in speculative market demand for options and futures, including technical influences in options and futures trading, and differences between the financial instruments being hedged and the instruments underlying the standard contracts available for trading. A decision as to whether, when and how to hedge involves the exercise of skill and judgment, and even a well-conceived hedge may be unsuccessful to some degree because of market behavior or unexpected interest rate trends. In addition, the fund's investment in exchange-traded options and futures and their resulting costs could limit the fund's gains in rising markets relative to those of the underlying funds, or to those of unhedged funds in general.

*Short positions* — The fund may suffer losses from short positions in futures contracts. Losses from short positions in futures contracts occur when the underlying index increases in value. As the underlying index increases in value, the holder of the short position in the corresponding futures contract is required to pay the difference in value of the futures contract resulting from the increase in the index on a daily basis. Losses from a short position in an index futures contract could potentially be very large if the value of the underlying index rises dramatically in a short period of time.

------

*Market conditions* — The prices of, and the income generated by, the securities held by an underlying fund may decline – sometimes rapidly or unpredictably – due to various factors, including events or conditions affecting the general economy or particular industries or companies; overall market changes; local, regional or global political, social or economic instability; governmental, governmental agency or central bank responses to economic conditions; levels of public debt and deficits; changes in inflation rates; and currency exchange rate, interest rate and commodity price fluctuations.

Economies and financial markets throughout the world are highly interconnected. Economic, financial or political events, trading and tariff arrangements, wars, terrorism, cybersecurity events, natural disasters, public health emergencies (such as the spread of infectious disease), bank failures and other circumstances in one country or region, including actions taken by governmental or quasi-governmental authorities in response to any of the foregoing, could have impacts on global economies or markets. As a result, whether or not an underlying fund invests in securities of issuers located in or with significant exposure to the countries affected, the value and liquidity of an underlying fund's investments may be negatively affected by developments in other countries and regions.

*Issuer risks* — The prices of, and the income generated by, securities held by an underlying fund may decline in response to various factors directly related to the issuers of such securities, including reduced demand for an issuer's goods or services, poor management performance, major litigation, investigations or other controversies related to the issuer, changes in the issuer's financial condition or credit rating, changes in government regulations affecting the issuer or its competitive environment and strategic initiatives such as mergers, acquisitions or dispositions and the market response to any such initiatives. An individual security may also be affected by factors relating to the industry or sector of the issuer or the securities markets as a whole, and conversely an industry or sector or the securities markets may be affected by a change in financial condition or other event affecting a single issuer. To the extent that the securities of issuers in the same or related industries or sectors behave similarly to each other, and these issuers make up a sizeable portion of the market, events affecting one issuer, industry or sector or the securities markets generally may have a larger impact. If such issuers represent a substantial portion of major market indices, or the economy, a downturn in their stock prices may have a disproportionate adverse effect on the overall equity markets, even if other segments of the market perform well. The underlying fund's portfolio managers invest in issuers based on their level of investment conviction. At times, the underlying fund may invest more significantly in a single issuer, which could increase the underlying fund's volatility and the risk of loss arising from the factors described above.

*Investing in growth-oriented stocks* — Growth-oriented common stocks and other equity-type securities (such as preferred stocks, convertible preferred stocks and convertible bonds) may involve larger price swings and greater potential for loss than other types of investments. These risks may be even greater in the case of smaller capitalization stocks.

*Investing outside the United States* — Securities of issuers domiciled outside the United States or with significant operations or revenues outside the United States, and securities tied economically to countries outside the United States, may lose value because of adverse political, social, economic or market developments (including social instability, regional conflicts, terrorism and war) in the countries or regions in which the issuers are domiciled, operate or generate revenue or to which the securities are tied economically. These securities may also lose value due to changes in foreign currency exchange rates against the U.S. dollar and/or currencies of other countries. Issuers of these securities may be more susceptible to actions of foreign governments, such as nationalization, currency blockage or the imposition of price controls, sanctions, or punitive taxes, each of which could adversely impact the value of these securities. Securities markets in certain countries may be more volatile and/or less liquid than those in the United States. Investments outside the United States may also be subject to different regulatory, legal, accounting, auditing, financial reporting and recordkeeping requirements, and may be more difficult to value, than those in the United States. In addition, the value of investments outside the United States may be reduced by foreign taxes, including foreign withholding taxes on interest and dividends. Further, there may be increased risks of delayed settlement of securities purchased or sold by an underlying fund, which could impact the liquidity of the fund's portfolio. The risks of investing outside the United States may be heightened in connection with investments in emerging markets.

*Investing in emerging markets* — Investing in emerging markets may involve risks in addition to and greater than those generally associated with investing in the securities markets of developed countries. For instance, emerging market countries tend to have less developed political, economic and legal systems than those in developed countries. Accordingly, the governments of these countries may be less stable and more likely to intervene in the market economy, for example, by imposing capital controls, nationalizing a company or industry, placing restrictions on foreign ownership and on withdrawing sale proceeds of securities from the country, and/or imposing punitive taxes that could adversely affect the prices of securities. Information regarding issuers in emerging markets may be limited, incomplete or inaccurate, and such issuers may not be subject to regulatory, accounting, auditing, and financial reporting and recordkeeping standards comparable to those to which issuers in more developed markets are subject. The underlying fund's rights with respect to its investments in emerging markets, if any, will generally be governed by local law, which may make it difficult or impossible for the underlying fund to pursue legal remedies or to obtain and enforce judgments in local courts. In addition, the economies of these countries may be dependent on relatively few industries, may have limited access to capital and may be more susceptible to changes in local and global trade conditions and downturns in the world economy. Securities markets in these countries can also be relatively small and have substantially lower trading volumes. As a result, securities issued in these countries may be more volatile and less liquid, more vulnerable to market manipulation, and more difficult to value, than securities issued in countries with more developed economies and/or markets. Less certainty with respect to security valuations may lead to additional challenges and risks in calculating the underlying fund's net asset value. Additionally, emerging markets are more likely to experience problems with the clearing and settling of trades and the holding of securities by banks, agents and depositories that are less established than those in developed countries.

*Investing in debt instruments* — The prices of, and the income generated by, bonds and other debt securities held by an underlying fund may be affected by factors such as the interest rates, maturities and credit quality of these securities.

Rising interest rates will generally cause the prices of bonds and other debt securities to fall. Also, when interest rates rise, issuers of debt securities that may be prepaid at any time, such as mortgage- or other asset-backed securities, are less likely to refinance existing debt

American Funds Insurance Series — Managed Risk Funds / Prospectus&nbsp;&nbsp;&nbsp;&nbsp; 10

------

securities, causing the average life of such securities to extend. A general change in interest rates may cause investors to sell debt securities on a large scale, which could also adversely affect the price and liquidity of debt securities and could also result in increased redemptions from the fund. Falling interest rates may cause an issuer to redeem, call or refinance a debt security before its stated maturity, which may result in the fund having to reinvest the proceeds in lower yielding securities. Longer maturity debt securities generally have greater sensitivity to changes in interest rates and may be subject to greater price fluctuations than shorter maturity debt securities.

Bonds and other debt securities are also subject to credit risk, which is the possibility that the credit strength of an issuer or guarantor will weaken or be perceived to be weaker, and/or an issuer of a debt security will fail to make timely payments of principal or interest and the security will go into default. Changes in actual or perceived creditworthiness may occur quickly. A downgrade or default affecting any of the fund's securities could cause the value of the fund's shares to decrease. Lower quality debt securities generally have higher rates of interest and may be subject to greater price fluctuations than higher quality debt securities. Credit risk is gauged, in part, by the credit ratings of the debt securities in which an underlying fund invests. However, ratings are only the opinions of the rating agencies issuing them and are not guarantees as to credit quality or an evaluation of market risk. The fund's investment adviser relies on its own credit analysts to research issuers and issues in assessing credit and default risks.

*Management* — The investment adviser to the fund and to the underlying funds actively manages each underlying fund's investments. Consequently, each underlying fund is subject to the risk that the methods and analyses, including models, tools and data, employed by the investment adviser in this process may be flawed or incorrect and may not produce the desired results. In addition, the fund is subject to the risk that the managed risk strategy or the methods employed by the subadviser in implementing the managed risk strategy may not produce the desired results. The occurrence of either or both of these events could cause the fund to lose value or its investment results to lag relevant benchmarks or other funds with similar objectives.

The following are additional risks associated with investing in the fund.

*Exposure to country, region, industry or sector* — Subject to its investment limitations, an underlying fund may have significant exposure to a particular country, region, industry or sector. Such exposure may cause the underlying fund to be more impacted by risks relating to and developments affecting the country, region, industry or sector, and thus its net asset value may be more volatile, than a fund without such levels of exposure. For example, if an underlying fund has significant exposure in a particular country, then social, economic, regulatory or other issues that negatively affect that country may have a greater impact on the underlying fund than on a fund that is more geographically diversified.

*Investing in depositary receipts* — Depositary receipts are securities that evidence ownership interests in, and represent the right to receive, a security or a pool of securities that have been deposited with a bank or trust depository. Such securities may be less liquid or may trade at a lower price than the underlying securities of the issuer. Additionally, receipt of corporate information about the underlying issuer and proxy disclosure may not be timely and there may not be a correlation between such information and the market value of the depositary receipts.

*Liquidity risk* — Certain underlying fund holdings may be or may become difficult or impossible to sell, particularly during times of market turmoil. Liquidity may be impacted by the lack of an active market for a holding, legal or contractual restrictions on resale, or the reduced number and capacity of market participants to make a market in such holding. Market prices for less liquid or illiquid holdings may be volatile or difficult to determine, and reduced liquidity may have an adverse impact on the market price of such holdings. Additionally, the sale of less liquid or illiquid holdings may involve substantial delays (including delays in settlement) and additional costs and the underlying fund may be unable to sell such holdings when necessary to meet its liquidity needs or to try to limit losses, or may be forced to sell at a loss.

*Investing in mortgage-related and other asset-backed securities* — Mortgage-related securities, such as mortgage-backed securities, and other asset-backed securities, include debt obligations that represent interests in pools of mortgages or other income-bearing assets, such as residential mortgage loans, home equity loans, mortgages on commercial buildings, consumer loans and equipment leases. While such securities are subject to the risks associated with investments in debt instruments generally (for example, credit, extension and interest rate risks), they are also subject to other and different risks. Mortgage-backed and other asset-backed securities are subject to changes in the payment patterns of borrowers of the underlying debt, potentially increasing the volatility of the securities and an underlying fund's net asset value. When interest rates fall, borrowers are more likely to refinance or prepay their debt before its stated maturity. This may result in an underlying fund having to reinvest the proceeds in lower yielding securities, effectively reducing the underlying fund's income. Conversely, if interest rates rise and borrowers repay their debt more slowly than expected, the time in which the mortgage-backed and other asset-backed securities are paid off could be extended, reducing an underlying fund's cash available for reinvestment in higher yielding securities. Mortgage-backed securities are also subject to the risk that underlying borrowers will be unable to meet their obligations and the value of property that secures the mortgages may decline in value and be insufficient, upon foreclosure, to repay the associated loans. Investments in asset-backed securities are subject to similar risks, as well as additional risks associated with the assets underlying those securities.

*Investments in future delivery contracts* — An underlying fund may enter into transactions involving future delivery contracts, such as to-be-announced (TBA) contracts and mortgage dollar rolls. These contracts involve the purchase or sale of mortgage-backed securities for settlement at a future date and predetermined price. When an underlying fund enters into a TBA commitment for the sale of mortgage-backed securities (which may be referred to as having a short position in such TBA securities), an underlying fund may or may not hold the types of mortgage-backed securities required to be delivered. An underlying fund may choose to roll these transactions in lieu of settling them.

When an underlying fund rolls the purchase of these types of future delivery transactions, an underlying fund simultaneously sells the mortgage-backed securities for delivery in the current month and repurchases substantially similar securities for delivery at a future date at

11&nbsp;&nbsp;&nbsp;&nbsp; American Funds Insurance Series — Managed Risk Funds / Prospectus

------

a predetermined price. When an underlying fund rolls the sale of these transactions rather than settling them, an underlying fund simultaneously purchases the mortgage-backed securities for delivery in the current month and sells substantially similar securities for delivery at a future date at a predetermined price. Such roll transactions can increase the turnover rate of an underlying fund and may increase the risk that market prices may move unfavorably between the original and new contracts, potentially resulting in losses or reduced returns for an underlying fund.

*Investing in securities backed by the U.S. government* — U.S. government securities are subject to market risk, interest rate risk and credit risk. Securities backed by the U.S. Treasury or the full faith and credit of the U.S. government are guaranteed only as to the timely payment of interest and principal when held to maturity. Accordingly, the current market values for these securities will fluctuate with changes in interest rates and the credit rating of the U.S. government. Notwithstanding that these securities are backed by the full faith and credit of the U.S. government, circumstances could arise that would prevent or delay the payment of interest or principal on these securities, which could adversely affect their value and cause the fund to suffer losses. Such an event could lead to significant disruptions in U.S. and global markets.

Securities issued by U.S. government-sponsored entities and federal agencies and instrumentalities that are not backed by the full faith and credit of the U.S. government are neither issued nor guaranteed by the U.S. government.

*Investing in inflation-linked bonds* — The values of inflation-linked bonds generally fluctuate in response to changes in real interest rates — i.e., rates of interest after factoring in inflation. A rise in real interest rates may cause the prices of inflation-linked securities to fall, while a decline in real interest rates may cause the prices to increase. Inflation-linked bonds may experience greater losses than other debt securities with similar durations when real interest rates rise faster than nominal interest rates. There can be no assurance that the value of an inflation-linked security will be directly correlated to changes in interest rates; for example, if interest rates rise for reasons other than inflation, the increase may not be reflected in the security's inflation measure.

Investing in inflation-linked bonds may also reduce an underlying fund's distributable income during periods of deflation. If prices for goods and services decline throughout the economy, the principal and income on inflation-linked securities may decline and result in losses to an underlying fund.

*Investing in swaps* — Swaps, including interest rate swaps and credit default swap indices, or CDSIs, are subject to many of the risks generally associated with investing in derivative instruments. Additionally, although swaps require no initial investment or only a small initial investment in the form of a deposit of initial margin, the amount of a potential loss on a swap could greatly exceed the initial amount invested. The use of swaps involves the risk that the investment adviser will not accurately predict anticipated changes in interest rates or other economic factors, which may result in losses to an underlying fund. If an underlying fund enters into a bilaterally negotiated swap, the counterparty may fail to perform in accordance with the terms of the swap. If a counterparty defaults on its obligations under a swap, the underlying fund may lose any amount it expected to receive from the counterparty, potentially including amounts in excess of the underlying fund's initial investment. Certain swaps are subject to mandatory central clearing or may be eligible for voluntary central clearing. Although clearing interposes a central clearinghouse as the ultimate counterparty to each participant's swap, central clearing will not eliminate (but may decrease) counterparty risk relative to uncleared bilateral swaps. Some swaps, such as CDSIs, may be dependent on both the individual credit of an underlying fund's counterparty and on the credit of one or more issuers of any underlying assets. If an underlying fund does not correctly evaluate the creditworthiness of its counterparty and, where applicable, of issuers of any underlying reference assets, the underlying fund's investment in a swap may result in losses to the underlying fund.

*Currency transactions* — In addition to the risks generally associated with investing in derivative instruments, the use of forward currency contracts involves the risk that currency movements will not be accurately predicted by the investment adviser, which could result in losses to an underlying fund. While entering into forward currency contracts could minimize the risk of loss due to a decline in the value of the hedged currency, it could also limit any potential gain that may result from an increase in the value of the currency. Additionally, the adviser may use forward currency contracts to increase exposure to a certain currency or to shift exposure to currency fluctuations from one country to another. Forward currency contracts may expose an underlying fund to potential gains and losses in excess of the initial amount invested.

*Interest rate risk* — The values and liquidity of the securities held by an underlying fund may be affected by changing interest rates. For example, the values of these securities may decline when interest rates rise and increase when interest rates fall. Longer maturity debt securities generally have greater sensitivity to changes in interest rates and may be subject to greater price fluctuations than shorter maturity debt securities. An underlying fund may invest in variable and floating rate securities. When the underlying fund holds variable or floating rate securities, a decrease in market interest rates will adversely affect the income received from such securities and the net asset value of the fund's shares. Although the values of such securities are generally less sensitive to interest rate changes than those of other debt securities, the value of variable and floating rate securities may decline if their interest rates do not rise as quickly, or as much, as market interest rates. Conversely, floating rate securities will not generally increase in value if interest rates decline. During periods of extremely low short-term interest rates, an underlying fund may not be able to maintain a positive yield or total return and, in relatively low interest rate environments, there are heightened risks associated with rising interest rates.

*Portfolio turnover* — The underlying fund may engage in frequent and active trading of its portfolio securities. Higher portfolio turnover may involve correspondingly greater transaction costs in the form of dealer spreads, brokerage commissions and other transaction costs on the sale of securities and on reinvestment in other securities. The sale of portfolio securities may also result in the realization of net capital gains, which are taxable when distributed to shareholders, unless the shareholder is exempt from taxation or his or her account is tax-favored. These costs and tax effects may adversely affect the underlying fund's returns to shareholders. The fund's portfolio turnover rate may vary from year to year, as well as within a year.

*Lending of portfolio securities —* Securities lending involves risks, including the risk that the loaned securities may not be returned in a timely manner or at all, which would interfere with the fund's ability to vote proxies or settle transactions, and/or the risk of a counterparty default. Additionally, the fund may lose money from the reinvestment of collateral received on loaned securities in investments that decline in value, default or do not perform as expected.

*Cybersecurity breaches* — The underlying fund may be subject to operational and information security risks through breaches in cybersecurity. Cybersecurity breaches can result from deliberate attacks or unintentional events, including "ransomware" attacks, the injection of computer viruses or malicious software code, the use of vulnerabilities in code to gain unauthorized access to digital information systems, networks or devices, or external attacks such as denial-of-service attacks on the investment adviser's or an affiliate's website that could render the underlying fund's network services unavailable to intended end-users. These breaches may, among other things, lead to the unauthorized release of confidential information, misuse of the underlying fund's assets or sensitive information, the disruption of the underlying fund's operational capacity, the inability of underlying fund shareholders to transact business, or the destruction of the underlying fund's physical infrastructure, equipment or operating systems. These events could cause the underlying fund to violate applicable privacy and other laws and could subject the underlying fund to reputational damage, additional costs associated with corrective measures and/or financial loss. The underlying fund may also be subject to additional risks if its third-party service providers, such as the underlying fund's investment adviser, transfer agent, custodian, administrators and other financial intermediaries, experience similar cybersecurity breaches and potential outcomes. Cybersecurity risks may also impact issuers of securities in which the underlying fund invests, which may cause the underlying fund's investments in such issuers to lose value.

*Large shareholder transactions risk* — The underlying fund may experience adverse effects when shareholders, including other underlying funds or accounts advised by the investment adviser, purchase or redeem, individually or in the aggregate, large amounts of shares relative to the size of the underlying fund. For example, when the investment adviser changes allocations in other underlying funds and accounts it manages, such changes may result in shareholder transactions in the underlying fund that are large relative to the size of the underlying fund. Such large shareholder redemptions may cause the underlying fund to sell portfolio securities at times when it would not otherwise do so, which may negatively impact the underlying fund's net asset value and liquidity. Similarly, large underlying fund share purchases may adversely affect the underlying fund's performance to the extent that the underlying fund is delayed in investing new cash and is required to maintain a larger cash position than it ordinarily would. These transactions may also accelerate the realization of taxable income to shareholders if such sales of investments resulted in gains, and may also increase transaction costs. In addition, a large redemption could result in the underlying fund's current expenses being allocated over a smaller asset base, leading to an increase in the underlying fund's expense ratio. These risks are heightened when the underlying fund is small.

In addition to the principal investment strategies described above, the fund has other investment practices that are described in the statement of additional information, which includes a description of other risks related to the fund's principal investment strategies and other investment practices. The fund's investment results will depend on the ability of the fund's investment adviser to navigate the risks discussed above as well as those described in the statement of additional information.

**Fund comparative indexes** — The MSCI All Country World ex USA Index is a free float-adjusted market capitalization-weighted index that is designed to measure equity market results in the global developed and emerging markets, excluding the United States. The index consists of more than 40 developed and emerging market country indexes. Results reflect dividends gross of withholding taxes through December 31, 2000, and dividends net of withholding taxes thereafter. This index is unmanaged, and its results include reinvested dividends and/or distributions but do not reflect the effect of sales charges, commissions, account fees, expenses or U.S. federal income taxes. The S&P Managed Risk Index Series is designed to simulate a dynamic protective portfolio that allocates between the underlying equity index and cash, based on realized volatilities of the underlying equity and bond indices, while maintaining a fixed allocation to the underlying bond index. These indices are generated and published under agreements between S&P Dow Jones Indices and Milliman Financial Risk Management LLC. This index is unmanaged, and its results include reinvested dividends and/or distributions but do not reflect the effect of sales charges, commissions, account fees, expenses or U.S. federal income taxes.

**Portfolio holdings** A description of the fund's policies and procedures regarding disclosure of information about its portfolio holdings is available in the statement of additional information.

**Information regarding the underlying funds** The investment objectives and principal investment strategies of the underlying funds are summarized below and on the following pages. They should not be construed as an offer to purchase or sell the underlying funds. For additional and more current information regarding the underlying funds, investors should read the current prospectuses and statements of additional information of the underlying funds.

Each fund will invest in some, but not all, of the underlying funds listed below. Some underlying funds may not be underlying investments for any fund, while others may serve as underlying investments for multiple funds. Each of the funds described in this prospectus relies on the professional judgment of the investment adviser to the funds and to the underlying funds to make decisions about the underlying funds' respective portfolio investments. The basic investment philosophy of the investment adviser is to seek to invest in attractively valued companies that, in its opinion, represent good, long-term investment opportunities. The investment adviser believes that an important way to accomplish this is through fundamental analysis, which may include meeting with company executives and employees, suppliers, customers and competitors. Securities may be sold when the investment adviser believes that they no longer represent relatively attractive investment opportunities.

**Underlying funds – Growth funds**

**Growth Fund** The fund's investment objective is to provide growth of capital.

The fund invests primarily in common stocks and seeks to invest in companies that appear to offer superior opportunities for growth of capital. The fund may invest up to 25% of its assets in common stocks and other securities outside the United States.

**EUPAC Fund™** The fund's investment objective is to provide you with long-term growth of capital.

The fund invests primarily in common stocks in Europe and the Pacific Basin that the investment adviser believes have the potential for growth. Growth stocks are stocks that the investment adviser believes have the potential for above-average capital appreciation.

Normally the fund will invest at least 80% of its net assets in securities of issuers in Europe and the Pacific Basin. A country will be considered part of Europe if it is part of the MSCI European indexes, and part of the Pacific Basin if any of its borders touches the Pacific Ocean. In determining the domicile of an issuer, the fund's investment adviser will generally look to the determination of MSCI Inc. (MSCI) for equity securities and Bloomberg for debt securities. In certain limited circumstances (including where relevant data is unavailable or the nature of a holding warrants special considerations), the adviser may also take into account additional factors, as applicable, including where the issuer's securities are listed; where the issuer is legally organized, maintains principal corporate offices, conducts its principal operations, generates revenues and/or has credit risk exposure; and the source of guarantees, if any, of such securities. The fund may invest a portion of its assets in common stocks and other securities of companies in emerging markets.

**Underlying funds – Growth-and-income funds**

**Growth-Income Fund** The fund's investment objectives are to achieve long-term growth of capital and income.

The fund invests primarily in common stocks or other securities that the investment adviser believes demonstrate the potential for appreciation and/or dividends. The fund may invest up to 15% of its assets outside the United States. The fund is designed for investors seeking both capital appreciation and income.

**Washington Mutual Investors Fund** The fund's investment objective is to produce income and to provide an opportunity for growth of principal consistent with sound common stock investing.

The fund invests primarily in common stocks of established companies that are listed on, or meet the financial listing requirements of, the New York Stock Exchange and have a strong record of earnings and dividends. The fund strives to accomplish its objective through fundamental research, careful selection and broad diversification. In the selection of common stocks and other securities for investment, current and potential income as well as the potential for long-term capital appreciation are considered. The fund seeks to provide an above-average yield in its quarterly income distribution in relation to the S&P 500 Index (a broad, unmanaged index). The fund strives to maintain a fully invested, diversified portfolio, consisting primarily of high-quality common stocks.

The fund has an "Eligible List" of securities considered appropriate for a prudent investor seeking opportunities for income and growth of principal consistent with common stock investing. The investment adviser generates and maintains the Eligible List and selects the fund's investments exclusively from the securities on the Eligible List.

**Underlying funds – Equity-income and balanced funds**

**Asset Allocation Fund** The fund's investment objective is to provide high total return (including income and capital gains) consistent with preservation of capital over the long term.

In seeking to pursue its investment objective, the fund varies its mix of equity securities, debt securities and money market instruments. Under normal market conditions, the fund's investment adviser expects (but is not required) to maintain an investment mix falling within the following ranges: 40%-80% in equity securities, 20%-50% in debt securities and 0%-40% in money market instruments and cash. As of December 31, 2025, the fund was approximately 65% invested in equity securities, 31% invested in debt securities and 4% invested in money market instruments and cash. The proportion of equities, debt and money market securities held by the fund varies with market conditions and the investment adviser's assessment of their relative attractiveness as investment opportunities.

The fund invests in a diversified portfolio of common stocks and other equity securities, bonds and other intermediate and long-term debt securities including U.S. government securities, and money market instruments (debt securities maturing in one year or less). The fund may invest up to 15% of its assets in common stocks and other equity securities of issuers domiciled outside the United States and up to 5% of its assets in debt securities tied economically to countries outside the United States. In addition, the fund may invest up to 25% of its debt assets in lower quality debt securities (rated Ba1 or below and BB+ or below by Nationally Recognized Statistical Rating Organizations designated by the fund's investment adviser or unrated but determined to be of equivalent quality by the fund's investment adviser). Such securities are sometimes referred to as "junk bonds."

**Underlying funds – Fixed-income funds**

**The Bond Fund of America<sup>®</sup>** The fund's investment objective is to provide as high a level of current income as is consistent with the preservation of capital.

The fund seeks to maximize your level of current income and preserve your capital by investing primarily in bonds. Normally the fund invests at least 80% of its assets in bonds and other debt securities, which may be represented by derivatives. The fund invests at least 60% of its assets in debt securities (excluding derivatives) rated A3 or better or A- or better by Nationally Recognized Statistical Ratings Organizations designated by the fund's investment adviser, or in debt securities that are unrated but determined to be of equivalent quality by the fund's investment adviser, and in U.S. government securities, money market instruments, cash or cash equivalents.

The fund may invest in debt securities and mortgage-backed securities issued by government-sponsored entities and federal agencies and instrumentalities that are not backed by the full faith and credit of the U.S. government.

The fund may invest in inflation-linked bonds issued by U.S. and non-U.S. governments, their agencies or instrumentalities, and corporations. Inflation-linked bonds are structured to protect against inflation by linking the bond's principal and interest payments to an inflation index, such as the Consumer Price Index for Urban Consumers, so that principal and interest adjust to reflect changes in the index.

The fund may invest in futures contracts and swaps, which are types of derivatives. A derivative is a financial contract, the value of which is based on the value of an underlying financial asset (such as a stock, bond or currency), a reference rate or a market index.

The fund may invest up to 5% of its assets in debt securities rated Ba1 or below and BB+ or below by Nationally Recognized Statistical Ratings Organizations designated by the fund's investment adviser, or in debt securities that are unrated but determined to be of equivalent quality by the fund's investment adviser. Securities rated Ba1 or below and BB+ or below are sometimes referred to as "junk bonds."

**U.S. Government Securities Fund<sup>®</sup>** The fund's investment objective is to provide a high level of current income consistent with prudent investment risk and preservation of capital.

Normally at least 80% of the fund's assets will be invested in securities that are guaranteed or sponsored by the U.S. government, its agencies and instrumentalities, including bonds and other debt securities denominated in U.S. dollars, which may be represented by derivatives. The fund may also invest in mortgage-backed securities issued by federal agencies and instrumentalities that are not backed by the full faith and credit of the U.S. government.

The fund may invest in inflation-linked bonds issued by U.S. and non-U.S. governments, their agencies or instrumentalities, and corporations. Inflation-linked bonds are structured to protect against inflation by linking the bond's principal and interest payments to an inflation index, such as the Consumer Price Index for Urban Consumers, so that principal and interest adjust to reflect changes in the index.

The fund may invest in futures contracts and swaps, which are types of derivatives. A derivative is a financial contract, the value of which is based on the value of an underlying financial asset (such as a stock, bond or currency), a reference rate or a market index.

**Management and organization**

**Investment adviser** Capital Research and Management Company, an experienced investment management organization founded in 1931, serves as the investment adviser to the Series and other funds, including each of the underlying funds and the American Funds. Capital Research and Management Company is a wholly owned subsidiary of The Capital Group Companies, Inc. and is located at 333 South Hope Street, Los Angeles, California 90071. The total management fee paid by each fund to its investment adviser for the most recent fiscal year, including any amounts waived, in each case expressed as a percentage of average net assets of that fund, appears in the Annual Fund Operating Expenses table for each fund. Please see the statement of additional information for further details. A discussion regarding the basis for the approval of the Series' Investment Advisory and Service Agreement by the Series' board of trustees is contained in the Series' Form N-CSR annual or semi-annual report in Form N-CSR for the most recent fiscal period.

Capital Research and Management Company manages equity assets through three equity investment divisions and fixed income assets through its fixed income investment division, Capital Fixed Income Investors. The three equity investment divisions — Capital International Investors, Capital Research Global Investors and Capital World Investors — make investment decisions independently of one another.

The equity investment divisions may, in the future, be incorporated as wholly owned subsidiaries of Capital Research and Management Company. In that event, Capital Research and Management Company would continue to be the investment adviser, and day-to-day investment management of equity assets would continue to be carried out through one or more of these subsidiaries. Although not currently contemplated, Capital Research and Management Company could incorporate its fixed income investment division in the future and engage it to provide day-to-day investment management of fixed income assets. Capital Research and Management Company and each of the funds it advises have received an exemptive order from the U.S. Securities and Exchange Commission that allows Capital Research and Management Company to use, upon approval of the funds' boards, its management subsidiaries and affiliates to provide day-to-day investment management services to the funds, including making changes to the management subsidiaries and affiliates providing such services. The Series' shareholders approved this arrangement; however, there is no assurance that Capital Research and Management Company will incorporate its investment divisions or exercise any authority granted to it under the exemptive order.

In addition, shareholders of the Series have approved a proposal to reorganize the Series into a Delaware statutory trust. However, the Series reserved the right to delay implementing the reorganization and has elected to do so.

**Portfolio management for the funds** Capital Research and Management Company is the investment adviser to the funds and the underlying funds. The investment adviser is responsible for the management of the funds and, subject to the review and approval of the Series' board of trustees, the selection of the subadviser to the funds, the monitoring and oversight of any such subadviser and the implementation of policies and procedures reasonably designed to ensure that such subadviser complies with the funds' respective investment objectives, strategies and restrictions.

Milliman Financial Risk Management LLC is the subadviser to the funds with respect to the management of the funds' managed risk strategies.

The table below shows the investment industry experience and role in management for each of the investment adviser's investment professionals primarily responsible for management of the funds.

**The Capital System<sup>TM</sup> for the underlying funds** Capital Research and Management Company uses a system of multiple portfolio managers in managing fund assets for the underlying funds. Under this approach, the portfolio of each underlying fund is divided into segments managed by individual managers. In addition, Capital Research and Management Company's investment analysts may make investment decisions with respect to a portion of each underlying fund's portfolio. Investment decisions are subject to the underlying fund's objective(s), policies and restrictions and the oversight of the appropriate investment-related committees of Capital Research and Management Company and its investment divisions.

Certain senior members of Capital Fixed Income Investors, the investment adviser's fixed income investment division, serve on the Portfolio Strategy Group. The group utilizes a research-driven process with input from the investment adviser's analysts, portfolio managers and economists to define investment themes on a range of macroeconomic factors, including duration, yield curve and sector allocation. Where applicable, the investment decisions made by a fund's fixed income portfolio managers are informed by the investment themes discussed by the group.

**Purchases and redemptions of shares** Shares of the Series are currently offered only to insurance company separate accounts as well as so-called "feeder funds" under master-feeder arrangements sponsored by insurance companies as underlying investments for such insurance companies' variable annuity contracts and variable life insurance policies. All such shares may be purchased or redeemed by the insurance company separate accounts (or feeder funds) at net asset value without any sales or redemption charges. These purchases and redemptions are made at the price next determined after such purchases and redemptions of units of the separate accounts (or feeder funds). The Series typically expects to remit redemption proceeds one business day following receipt and acceptance of a redemption order, regardless of the method the Series uses to make such payment (e.g., check, wire or automated clearing house transfer). However, payment may take longer than one business day and may take up to seven days as generally permitted by the Investment Company Act of 1940, as amended (the "1940 Act"). Under the 1940 Act, the Series may be permitted to pay redemption proceeds beyond seven days under certain limited circumstances.

Under normal conditions, the Series typically expects to meet shareholder redemptions from a reserve of highly liquid assets, such as cash or cash equivalents. The Series may use additional methods to meet shareholder redemptions, if they become necessary. These methods may include, but are not limited to, the sale of portfolio assets, the use of overdraft protection afforded by the Series' custodian bank, borrowing from a line of credit and making payment with fund securities or other fund assets rather than in cash (as further discussed in the following paragraph).

Although payment of redemptions normally will be in cash, the Series may pay the redemption price wholly or partly with portfolio securities or other fund assets under conditions and circumstances determined by the Series' board of trustees. On the same redemption date, some shareholders may be paid in whole or in part in securities (which may differ among those shareholders), while other shareholders may be paid entirely in cash. In general, in-kind redemptions to affiliated shareholders will as closely as practicable represent the affiliated shareholder's pro rata share of the Series' securities, subject to certain exceptions. Securities distributed in-kind to unaffiliated shareholders will be selected by the investment adviser in a manner the investment adviser deems to be fair and reasonable to the Series' shareholders. The disposal of the securities received in-kind may be subject to brokerage costs and, until sold, such securities remain subject to market risk and liquidity risk, including the risk that such securities are or become difficult to sell. If the Series pays your redemption with illiquid or less liquid securities, you will bear the risk of not being able to sell such securities.

**Frequent trading of fund shares** The Series and Capital Client Group, Inc., the Series' distributor, reserve the right to reject any purchase order for any reason. The funds are not designed to serve as vehicles for frequent trading. Frequent trading of fund shares may lead to increased costs to the funds and less efficient management of the funds' portfolios, potentially resulting in dilution of the value of the shares held by long-term shareholders. Accordingly, purchases, including those that are part of exchange activity, that the Series or Capital Client Group, Inc. has determined could involve actual or potential harm to a fund may be rejected.

The Series, through its transfer agent, American Funds Service Company, has agreements with the Series' insurance relationships to maintain its surveillance procedures that are designed to detect frequent trading in fund shares. The agreements generally require the insurance companies to (i) provide, upon request from a fund, the Series or their agent, certain identifying and account information regarding contract owners who invest in fund shares through an insurance company account and (ii) execute instructions from a fund, the Series or their agent to restrict further purchases or exchanges of fund shares by a contract owner who the Series has identified as having engaged in potentially harmful market timing or frequent trading. Under these procedures, various analytics are used to evaluate factors that may be indicative of frequent trading. For example, transactions in fund shares that exceed certain monetary thresholds may be scrutinized. American Funds Service Company may work with the insurance company separate accounts or feeder funds to apply their procedures that American Funds Service Company believes are reasonably designed to enforce the frequent trading policies of the Series. You should refer to disclosures provided by the insurance company with which you have a contract to determine the specific trading restrictions that apply to you.

Under the Series' frequent trading policy, certain trading activity will not be treated as frequent trading, such as:

· retirement plan contributions, loans and distributions (including hardship withdrawals) identified as such on the retirement plan recordkeeper's system;

· purchases and redemptions in community foundation accounts;

· purchase transactions involving in-kind transfers of fund shares, if the entity maintaining the contract owner's account is able to identify the transaction as one of these types of transactions;

· transactions by certain intermediaries in accordance with established hedging programs approved by the fund's investment adviser; and

· systematic redemptions and purchases if the entity maintaining the contract owner's account is able to identify the transaction as a systematic redemption or purchase.

Generally, purchases and redemptions will not be considered "systematic" unless the transaction is prescheduled for a specific date.

American Funds Service Company will monitor for other types of activity that could potentially be harmful to the Series – for example short-term trading activity in multiple funds. If American Funds Service Company identifies any activity that may constitute frequent trading, it reserves the right to contact the insurance company separate account or feeder fund and request that the separate account or feeder fund either provide information regarding an account owner's transactions or restrict the account owner's trading. If American Funds Service Company is not satisfied that insurance company separate account or feeder fund has taken appropriate action, American Funds Service Company may terminate the separate account's or feeder fund's ability to transact in fund shares.

There is no guarantee that all instances of frequent trading in fund shares will be prevented.

**Notwithstanding the Series' surveillance procedures described above, all transactions in fund shares remain subject to the right of the Series, Capital Client Group, Inc. and American Funds Service Company to restrict potentially abusive trading generally, including the types of transactions described above that will not be prevented.**

**Valuing shares** The net asset value of each share class of each fund is calculated based in part upon the net asset value of the share class of the underlying funds in which the fund invests. The prospectus for each underlying fund explains the circumstances under which the underlying fund will use fair value pricing and the effects of using fair value pricing. The net asset value of each share class of a fund is the value of a single share of that class. Net asset value is computed by adding a class's share of the value of a fund's investments, cash and other assets, subtracting the class's share of the fund's liabilities allocated to the class, and dividing the result by the number of shares of that class that are outstanding. Realized investment income and gain is included in the fund's net asset value until the ex-dividend date, when the declared dividend amount is treated as a fund liability. The net asset value per share is calculated once daily as of the close of regular trading on the New York Stock Exchange, normally 4 p.m. New York time, each day the New York Stock Exchange is open. If the New York Stock Exchange makes a scheduled (e.g., the day after Thanksgiving) or an unscheduled close prior to 4 p.m. New York time, the net asset value of each fund will be determined at approximately the time the New York Stock Exchange closes on that day. If on such a day market quotations and prices from third-party pricing services are not based as of the time of the early close of the New York Stock Exchange but are as of a later time (up to approximately 4 p.m. New York time), for example because the market remains open after the close of the New York Stock Exchange, those later market quotations and prices will be used in determining the funds' net asset value.

Equity securities and options contracts are valued primarily on the basis of market quotations, and debt securities are valued primarily on the basis of prices from third-party pricing services due to the lack of market quotations. Futures contracts are valued primarily on the basis of settlement prices. The underlying funds' portfolio investments are valued in accordance with procedures for making fair value determinations if market quotations are not readily available, including procedures to determine the representativeness of third-party vendor prices, or in the event market quotations or third-party vendor prices are not considered reliable. For example, if events occur between the close of markets outside the United States and the close of regular trading on the New York Stock Exchange that, in the opinion of the investment adviser, materially affect the value of any of the underlying funds' equity securities that trade principally in those international markets, those securities will be valued in accordance with fair value procedures. Similarly, fair value procedures will be employed if an issuer defaults on its debt securities and there is no market for its securities. Use of these procedures is intended to result in more appropriate net asset values and, where applicable, to reduce potential arbitrage opportunities otherwise available to short-term investors.

Because the underlying funds may hold securities that are listed primarily on foreign exchanges that trade on weekends or days when the funds do not price their shares, the values of securities held in the funds may change on days when you will not be able to purchase or redeem fund shares.

Shares of the funds will be purchased or sold at the net asset value next determined after receipt of requests from the appropriate insurance company. Requests received by the appropriate insurance company prior to 4 p.m. New York time and communicated by the insurance company to the Series or its agent will be purchased or sold at that day's net asset value. Orders in good order received after the New York Stock Exchange closes (scheduled or unscheduled) will be processed at the net asset value (plus any applicable sales charge) calculated on the following business day.

**Plan of distribution** The Series has adopted a plan of distribution for Class P2 shares under which it may finance activities intended primarily to sell shares, provided that the categories of expenses are approved in advance by the Series' board of trustees. The plan provides for annual expenses of .50%, and the Series' board of trustees has authorized payments of .25% for Class P2 shares. The distribution fees expected to be paid by each fund, as a percentage of average net assets, are indicated in this prospectus in the Annual Fund Operating Expenses table for each fund. Since these fees are paid out of each fund's assets on an ongoing basis, over time they may cost you more than paying other types of sales charges or service fees and reduce the return of an investment in Class P2 shares.

**Other compensation to dealers** Capital Client Group, Inc., at its expense, provides additional compensation to insurance companies. These payments may be made, at the discretion of Capital Client Group, Inc., to insurance companies (or their affiliates) that have sold shares of the funds of the American Funds Insurance Series and American Funds as the exclusive underlying investments to their variable annuity contracts. A number of factors will be considered in determining payments, including the sales, assets, and the quality of the insurance company's relationship with Capital Client Group, Inc. The payment will typically be determined using a formula applied consistently to insurance companies based on the relevant facts and circumstances. Aggregate payments made by Capital Client Group, Inc. to insurance companies may also change from year to year. Only assets and deposits in variable annuity contracts that offer exclusively shares of the funds of the American Funds Insurance Series and American Funds are included in the formula. Further, assets for which the insurance company, or an affiliated broker-dealer, acts as an ERISA investment fiduciary are generally excluded from the formula. Capital Client Group, Inc. makes these payments to help defray the costs incurred by qualifying insurance companies in connection with efforts to educate their sales force about the American Funds Insurance Series and American Funds so that they help financial advisers make recommendations and provide services that are suitable and meet contractholders' needs. These payments may also be made to help defray the costs associated with the insurance company's provision of account-related services and activities and support the insurance company's distribution activities. Capital Client Group, Inc. will, on a periodic basis, determine the advisability of continuing these payments. As of May 1, 2026, the insurance companies (or their affiliates) that Capital Client Group, Inc. anticipates will receive additional compensation based on prior payments include Lincoln National Life Insurance Co.

Firms receiving additional compensation payments must sign a letter acknowledging the purpose of the payment and Capital Client Group, Inc.'s goal that the payment will help facilitate education of their sales force about the American Funds Insurance Series and American Funds to help financial professionals make suitable recommendations and better serve their clients who invest in the funds as underlying investments to variable annuity contracts. The letters generally require the firms to (1) offers shares of the funds of the American Funds Insurance Series and American Funds as the exclusive underlying investments to their variable annuity contracts, and (2) provide Capital Client Group, Inc. broad access to their sales force and product platforms and develop a business plan to achieve such access.

Capital Client Group, Inc. may also pay expenses associated with meetings and other training and educational opportunities conducted by insurance companies, selling dealers, advisory platform providers and other intermediaries to facilitate educating financial professionals and shareholders about the American Funds Insurance Series and American Funds. For example, some of these expenses may include, but not be limited to, meeting sponsor fees, meeting location fees, fees for data and reporting, and fees to obtain lists of financial professionals to better tailor training and education opportunities. In addition, Capital Client Group, Inc. and/or its affiliates may make payments to third parties for platform fees and other services.

If investment advisers, distributors or other affiliates of mutual funds pay additional compensation or other incentives to insurance companies in differing amounts, insurance companies and the financial professionals with which they interact may have financial incentives for recommending a particular mutual fund over other mutual funds or investments, creating a potential conflict of interest. You should consult with your financial professional and review carefully any disclosure by your financial professional's firm as to compensation received.

**Fund expenses** In periods of market volatility, assets of the funds and/or the applicable underlying funds may decline significantly, causing total annual fund operating expenses (as a percentage of the value of your investment) to become higher than the numbers shown in the Annual Fund Operating Expenses tables in this prospectus.

Each fund will invest in Class 1 shares of the applicable underlying fund(s). Accordingly, fees and expenses of the underlying fund(s) reflect current expenses of the Class 1 shares of the underlying fund(s). The "Other expenses" items in the Annual Fund Operating Expenses tables in this prospectus are based on expenses as of each fund's most recently completed fiscal year. These items include third-party expenses, such as custodial, legal, audit, accounting, regulatory reporting and pricing vendor services, and an administrative services fee provided by the insurance companies that include the funds as an underlying investment in their variable contracts. Each fund will pay an insurance administration fee of .25% to these insurance companies for providing certain services pursuant to an insurance administrative services plan adopted by the Series.

**Investment results** All fund results in the "Investment results" section of this prospectus reflect the reinvestment of dividends and capital gains distributions, if any. Unless otherwise noted, fund results reflect any fee waivers and/or expense reimbursements in effect during the period presented.

**Distributions and taxes** Each fund of the Series intends to qualify as a "regulated investment company" under the Internal Revenue Code. In any fiscal year in which a fund so qualifies and distributes to shareholders its investment company taxable income and net realized capital gain, the fund itself is relieved of federal income tax.

It is the Series' policy to distribute to the shareholders (the insurance company separate accounts) all of its investment company taxable income and capital gain for each fiscal year.

#### See the applicable contract prospectus for information regarding the federal income tax treatment of the contracts and distributions to the separate accounts.

**Financial highlights** The Financial Highlights table is intended to help you understand a fund's results for the past five fiscal years (or, if shorter, the period of operations). Certain information reflects financial results for a single share of a particular class. The total returns in the table represent the rate that an investor would have earned or lost on an investment in a fund (assuming reinvestment of all dividends and capital gain distributions). Where indicated, figures in the table reflect the impact, if any, of certain waivers/reimbursements from Capital Research and Management Company. For more information about these waivers/reimbursements, see the fund's statement of additional information and Form N-CSR. The information in the Financial Highlights table has been audited by PricewaterhouseCoopers LLP, whose current report, along with the funds' financial statements, is included in the statement of additional information, which is available upon request. Figures shown do not reflect insurance contract fees and expenses. If insurance contract fees and expenses were reflected, results would be lower.

**Certain investment limitations and guidelines**

The following limitations and guidelines are considered at the time of purchase, under normal circumstances, and are based on a percentage of each fund's net assets unless otherwise noted. This summary is not intended to reflect all of the fund's investment limitations.

#### Managed Risk EUPAC Fund
· The fund pursues its investment objective by:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; · seeking to invest:

o 85% of its assets in shares of American Funds Insurance Series – EUPAC Fund (the "EUPAC Fund"), and

o the remainder of its assets in shares of The Bond Fund of America and in cash and futures and options contracts,

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; · while seeking to manage portfolio volatility and risk of loss through the use of hedge instruments, including positions in exchange-traded options and futures contracts.

· The goal of the fund's managed risk strategy is to stabilize the volatility of the fund around a target volatility level and reduce the downside exposure of the fund during periods of significant market declines. In situations of extreme market volatility, the positions held in exchange-traded equity index put options and in exchange-traded equity index futures could potentially eliminate the fund's net economic exposure to equity securities.

· The fund will also hold cash, cash equivalents, money market fund shares and/or U.S. Treasury futures.

· The fund invests in hedge instruments pursuant to an order from the U.S. Securities and Exchange Commission granting an exemption from Rule 12d1-2(a) under the Investment Company Act of 1940 (File No. 812-14007 / Release No. 30033).

 **<u>The following limitations and guidelines are applicable to the EUPAC Fund:</u>** 

**General**

· Normally, the fund will invest at least 80% of its net assets in securities of issuers in Europe and the Pacific Basin. A country will be considered part of Europe if it is part of the MSCI European indexes and part of the Pacific Basin if any of its borders touches the Pacific Ocean. In determining the domicile of an issuer, the underlying fund's investment adviser will generally look to the determination of MSCI Inc. (MSCI) for equity securities and Bloomberg for debt securities. In certain limited circumstances (including when relevant data is unavailable or the nature of a holding warrants special considerations), the underlying fund's adviser may also take into account additional factors, as applicable, including where the issuer's securities are listed; where the issuer is legally organized, maintains principal corporate offices, conducts its principal operations, generates revenues and/or has credit risk exposure; and the source of guarantees, if any, of such securities. The fund may invest a portion of its assets in common stocks and other securities of companies in emerging markets.

American Funds Insurance Series – Managed Risk Funds — Page 2

------

· Although the United States is considered part of the Pacific Basin, the EUPAC Fund will not generally purchase equity securities of issuers domiciled in the United States. However, the EUPAC Fund may invest up to 10% of its assets in securities of issuers domiciled in the United States (excluding cash, cash equivalents and securities held as collateral issued by U.S. issuers, which will be treated as Pacific Basin assets).

· The EUPAC Fund invests primarily in the common stocks located outside the United States. The EUPAC Fund may invest a portion of its assets in companies located in emerging markets.

#### Debt instruments
· The EUPAC Fund may invest up to 5% of its assets in straight debt securities (i.e., not convertible into equity) rated Baa1 or below and BBB+ or below by Nationally Recognized Statistical Rating Organizations or in unrated securities that are determined to be of equivalent quality by the EUPAC Fund's investment adviser.

· The EUPAC Fund currently intends to consider the ratings from Moody's Investors Services, S&P Global Ratings and Fitch Ratings. If agency ratings of a security differ, the security will be considered to have received the highest of these ratings, consistent with the EUPAC Fund's investment policies.

**The following limitations and guidelines are applicable to The Bond Fund of America:**

· The fund will invest at least 80% of its assets in bonds and other debt instruments, including cash equivalents and certain preferred securities. For purposes of this investment guideline, investments may be represented by derivative instruments, such as futures contracts and swaps.

· The fund will invest at least 60% of its assets in debt securities rated A3 or better or A- or better by Nationally Recognized Statistical Rating Organizations, or NRSROs, designated by the fund's investment adviser or unrated but determined to be of equivalent quality by the fund's investment adviser, and in U.S. government securities, money market instruments, cash or cash equivalents.

· The fund may invest up to 40% of its assets in debt securities rated below A3 and below A- by NRSROs designated by the fund's investment adviser or unrated but determined to be of equivalent quality by the fund's investment adviser.

· The fund may invest up to 5% of its assets in debt securities rated Ba1 or below and BB+ or below by NRSROs designated by the fund's investment adviser or unrated but determined to be of equivalent quality by the fund's investment adviser.

· The fund currently intends to consider the ratings from Moody's Investors Service, S&P Global Ratings and Fitch Ratings. If agency ratings of a security differ, the security will be considered to have received the highest of these ratings, consistent with the fund's investment policies.

· While the fund may not make direct purchases of common stocks or warrants or rights to acquire common stocks, the fund may invest in debt securities that are issued together with common stock or other equity interests or in securities that have equity conversion, exchange or purchase rights. The fund may hold up to 5% of its assets in common stock, warrants and rights acquired after sales of the corresponding debt securities or received in exchange for debt securities.

American Funds Insurance Series – Managed Risk Funds — Page 3

------

· For purposes of determining whether an investment is made in a particular country or geographic region, the fund's investment adviser will generally look to the domicile of the issuer in the case of equity securities or to the country to which the security is tied economically in the case of debt securities. In doing so, the fund's investment adviser will generally look to the determination of MSCI Inc. (MSCI) for equity securities and Bloomberg for debt securities. In certain limited circumstances (including when relevant data is unavailable or the nature of a holding warrants special considerations), the adviser may also take into account additional factors, as applicable, including where the issuer's securities are listed; where the issuer is legally organized, maintains principal corporate offices, conducts its principal operations, generates revenues and/or has credit risk exposure; and the source of guarantees, if any, of such securities.]

The funds may experience difficulty liquidating certain portfolio securities during significant market declines or periods of heavy redemptions.

**Description of certain securities, investment techniques and risks**

The descriptions below are intended to supplement the material in the prospectus under "Investment objectives, strategies and risks" which provides information about the funds and the underlying funds.

**<u>The funds</u>**

The following descriptions of securities and techniques apply to the funds.

**Options** — An option on a security (or an index) is a contract that gives the holder of the option, in return for a premium payment, the right to buy from (in the case of a call) or sell to (in the case of a put) the writer of the option the security underlying the option (or the cash value of the index underlying the option) at a specified exercise price. The writer of an option on a security has the obligation upon exercise of the option to deliver the underlying security upon payment of the exercise price (in the case of a call) or to pay the exercise price upon delivery of the underlying security (in the case of a put). Upon exercise, the writer of an option on an index is obligated to pay the difference between the cash value of the index and the exercise price multiplied by a specified multiplier for the index option.

As part of its managed risk strategy, the fund will purchase put options on equity indexes in standardized contracts traded on foreign or domestic securities exchanges, boards of trade, or similar entities. By purchasing a put option, the fund obtains the right (but not the obligation) to sell the instrument underlying the option (or the cash value of the index underlying the option) at a specified exercise price, referred to as the strike price. In return for this right, the fund pays the current market price, or the option premium, for the option. The fund may terminate its position in a put option by allowing the option to expire or by exercising the option. If the option is allowed to expire, the fund will lose the entire premium. If the option is exercised, the fund completes the sale of the underlying instrument (or delivers the cash value of the index underlying the option) at the strike price. The fund may also terminate a put option position by entering into opposing close-out transactions in advance of the option expiration date.

As a buyer of a put option, the fund can expect to realize a gain if the price of the underlying instrument or index falls substantially. However, if the price of the underlying instrument or index does not fall enough to offset the cost of purchasing the option, the fund can expect to suffer a loss, albeit a loss limited to the amount of the option premium plus any applicable transaction costs.

As part of its managed risk strategy, the fund may also purchase exchange-traded equity index call options. The features of call options are essentially the same as those of put options, except that the purchaser of a call option obtains the right (but not the obligation) to purchase, rather than sell, the underlying instrument (or the cash value of the index underlying the option) at the specified strike price. The buyer of a call option typically attempts to participate in potential price increases of the underlying instrument or index with risk limited to the cost of the option if the price of the underlying instrument or index falls. At the same time, the call option buyer can expect to suffer a loss if the price of the underlying instrument or index does not rise sufficiently to offset the cost of the option.

Although the fund's investment adviser and subadviser expect that the fund will, at all times, retain a net long position in exchange-traded equity index put options, in certain market conditions, the fund may sell, or write, options on equity indexes. The writer of a put or call option takes the opposite side of the transaction from the option's purchaser. In return for receipt of the option premium, the writer assumes the obligation to pay or receive the strike price for the option's underlying instrument or index if the other party to the option chooses to exercise it. The writer may seek to terminate a position in a put option before exercise by closing out the option. If the market for the relevant put option is not liquid, however, the writer must continue to be prepared to pay the strike price while the option is outstanding, regardless of price changes.

American Funds Insurance Series – Managed Risk Funds — Page 5

------

If the price of the underlying instrument or index rises, a put writer would generally expect to profit, although its gain would be limited to the amount of the premium it received. If the price of the underlying instrument or index remains the same over time, it is likely that the writer would also profit because it should be able to close out the option at a lower price. If the price of the underlying instrument or index falls, the put writer would expect to suffer a loss. This loss should be less than the loss from purchasing the underlying instrument or exposure to the underlying index directly, however, because the premium received for writing the option should mitigate the effects of the decline.

Writing a call option obligates the writer to sell or deliver the option's underlying instrument or to make a net cash settlement payment, as applicable, in return for the strike price upon exercise of the option. The characteristics of writing call options are similar to those of writing put options, except that writing calls generally is a profitable strategy if prices remain the same or fall. Through receipt of the option premium, a call writer should mitigate the effects of a price increase. At the same time, because a call writer must be prepared to deliver the underlying instrument or make a net cash settlement payment, as applicable, in return for the strike price, even if its current value is greater, a call writer gives up some ability to participate in security price increases.

The fund will cover its obligations when it writes call or put options. For a call option on an index, the option is covered if the fund maintains with its custodian liquid assets in an amount equal to the fund's net obligation under the option. A written call option is also covered if the fund holds a call on the same index as the call written where the exercise price of the call held is (*i*) equal to or less than the exercise price of the call written or (*ii*) greater than the exercise price of the call written, provided the difference is maintained by the fund in segregated liquid assets. A written put option on an index is covered if the fund segregates liquid assets equal to the exercise price. A put option on an index is also covered if the fund holds a put on the same index as the put written where the exercise price of the put held is (*i*) equal to or greater than the exercise price of the put written or (*ii*) less than the exercise price of the put written, provided the difference is maintained by the fund in segregated liquid assets. Obligations under written call and put options so covered will not be deemed to be senior securities for the purposes of the fund's investment restrictions concerning senior securities and borrowings.

Several risks are associated with transactions in options on securities and on indexes. For example, there are significant differences between the securities and options markets that could result in an imperfect correlation between these markets, effectively causing a given transaction not to achieve its objectives. When a put or call option on a particular security or index is purchased to hedge against price movements in a related security or index, the price to close out the put or call option may move more or less than the price of the related security or index.

Options prices can diverge from the prices of their underlying instruments or indexes for a number of reasons. Options prices are affected by such factors as current and anticipated short-term interest rates, changes in volatility of the underlying instrument or index, and the time remaining until expiration of the contract, which may not affect security prices in the same way. Imperfect correlation may also result from differing levels of demand in the options and futures markets and the securities markets, from structural differences in how options and futures and securities are traded, or from imposition of daily price fluctuation limits or trading halts. The fund may purchase or sell options contracts with a greater or lesser value than the securities it wishes to hedge or intends to purchase in order to attempt to compensate for differences in volatility between the contract and the securities, although this may not be successful in all cases. If price changes in the fund's options positions are poorly correlated with its other investments, the positions may fail to produce anticipated gains or result in losses that are not offset by gains in other investments.

There is no assurance that a liquid market will exist for any particular options contract at any particular time. Options may have relatively low trading volumes and liquidity if their strike prices are not close to the current prices of the underlying instruments or indexes. In addition, exchanges may establish daily

American Funds Insurance Series – Managed Risk Funds — Page 6

------

price fluctuation limits for exchange-traded options contracts and may halt trading if a contract's price moves upward or downward more than the limit in a given day. On volatile trading days when the price fluctuation limit is reached or a trading halt is imposed, it may be impossible to enter into new positions or to close out existing positions. If the market for a contract is not liquid because of price fluctuation limits or otherwise, it could prevent prompt liquidation of unfavorable positions and could potentially require the fund to continue to hold a position until delivery or expiration regardless of changes in its value. As a result, the fund's access to other assets held to cover its options positions could also be impaired.

Combined positions involve purchasing and writing options in combination with each other, or in combination with futures or forward contracts, in order to adjust the risk and return profile of the fund's overall position. For example, purchasing a put option and writing a call option on the same underlying instrument or index would construct a combined position whose risk and return characteristics are similar to selling a futures contract. Another possible combined position would involve writing a call option at one strike price and buying a call option at a lower price to reduce the risk of the written call option in the event of a substantial price increase. Because such combined options positions involve multiple trades, they result in higher transaction costs and may be more difficult to open and close out.

**Futures** — The fund may enter into futures contracts as part of the managed risk strategy. A futures contract is an agreement to buy or sell a security or other financial instrument (the "reference asset") for a set price on a future date. Futures contracts are standardized, exchange-traded contracts, and, when a futures contract is bought or sold, the fund will incur brokerage fees and will be required to maintain margin deposits.

Unlike when the fund purchases or sells a security, such as a stock or bond, no price is paid or received by the fund upon the purchase or sale of a futures contract. When the fund enters into a futures contract, the fund is required to deposit with its futures broker, known as a futures commission merchant ("FCM"), a specified amount of liquid assets in a segregated account in the name of the FCM at the applicable derivatives clearinghouse or exchange. This amount, known as initial margin, is set by the futures exchange on which the contract is traded and may be significantly modified during the term of the contract. The initial margin is in the nature of a performance bond or good faith deposit on the futures contract, which is returned to the fund upon termination of the contract, assuming all contractual obligations have been satisfied. Additionally, on a daily basis, the fund pays or receives cash, or variation margin, equal to the daily change in value of the futures contract. Variation margin does not represent a borrowing or loan by the fund but is instead a settlement between the fund and the FCM of the amount one party would owe the other if the futures contract expired. In computing daily net asset value, the fund will mark-to-market its open futures positions. In the event of the bankruptcy or insolvency of an FCM that holds margin on behalf of the fund, the fund may be entitled to return of margin owed to it only in proportion to the amount received by the FCM's other customers, potentially resulting in losses to the fund. An event of bankruptcy or insolvency at a clearinghouse or exchange holding initial margin could also result in losses for the fund.

When the fund invests in futures contracts and deposits margin with an FCM, the fund becomes subject to so-called "fellow customer" risk – that is, the risk that one or more customers of the FCM will default on their obligations and that the resulting losses will be so great that the FCM will default on its obligations and margin posted by one customer, such as the fund, will be used to cover a loss caused by a different defaulting customer. Applicable Commodity Futures Trading Commission ("CFTC") rules generally prohibit the use of one customer's funds to meet the obligations of another customer and limit the ability of an FCM to use margin posed by non-defaulting customers to satisfy losses caused by defaulting customers. As a general matter, an FCM is required to use its own funds to meet a defaulting customer's obligations. While a customer's loss would likely need to be substantial before non-defaulting customers would be exposed to loss on account of fellow customer risk, applicable CFTC rules nevertheless permit the commingling of margin and do not limit the mutualization of

American Funds Insurance Series – Managed Risk Funds — Page 7

------

customer losses from investment losses, custodial failures, fraud or other causes. If the loss is so great that, notwithstanding the application of an FCM's own funds, there is a shortfall in the amount of customer funds required to be held in segregation, the FCM could default and be placed into bankruptcy. Under these circumstances, bankruptcy law provides that non-defaulting customers will share pro rata in any shortfall. A shortfall in customer segregated funds may also make the transfer of the accounts of non-defaulting customers to another FCM more difficult.

Although certain futures contracts, by their terms, require actual future delivery of and payment for the reference asset, in practice, most futures contracts are usually closed out before the delivery date by offsetting purchases or sales of matching futures contracts. Closing out an open futures contract purchase or sale is effected by entering into an offsetting futures contract sale or purchase, respectively, for the same aggregate amount of the identical reference asset and the same delivery date with the same FCM. If the offsetting purchase price is less than the original sale price (in each case taking into account transaction costs, including brokerage fees), the fund realizes a gain; if it is more, the fund realizes a loss. Conversely, if the offsetting sale price is more than the original purchase price (in each case taking into account transaction costs, including brokerage fees), the fund realizes a gain; if it is less, the fund realizes a loss.

The value of a futures contract tends to increase and decrease in tandem with the value of its underlying reference asset. Purchasing futures contracts will, therefore, tend to increase the fund's exposure to positive and negative price fluctuations in the reference asset, much as if the fund had purchased the reference asset directly. When the fund sells a futures contract, by contrast, the value of its futures position will tend to move in a direction contrary to the market for the reference asset. Accordingly, selling futures contracts will tend to offset both positive and negative market price changes, much as if the reference asset had been sold.

There is no assurance that a liquid market will exist for any particular futures contract at any particular time. Futures exchanges may establish daily price fluctuation limits for futures contracts and may halt trading if a contract's price moves upward or downward more than the limit in a given day. On volatile trading days, when the price fluctuation limit is reached and a trading halt is imposed, it may be impossible to enter into new positions or close out existing positions. If the market for a futures contract is not liquid because of price fluctuation limits or other market conditions, the fund may be prevented from promptly liquidating unfavorable futures positions and the fund could be required to continue to hold a position until delivery or expiration regardless of changes in its value, potentially subjecting the fund to substantial losses. Additionally, the fund may not be able to take other actions or enter into other transactions to limit or reduce its exposure to the position. Under such circumstances, the fund would remain obligated to meet margin requirements until the position is cleared. As a result, the fund's access to other assets posted as margin for its futures positions could also be impaired.

Although futures exchanges generally operate similarly in the United States and abroad, foreign futures exchanges may follow trading, settlement and margin procedures that are different than those followed by futures exchanges in the United States. Futures contracts traded outside the United States may not involve a clearing mechanism or related guarantees and may involve greater risk of loss than U.S.-traded contracts, including potentially greater risk of losses due to insolvency of a futures broker, exchange member, or other party that may owe initial or variation margin to the fund. Margin requirements on foreign futures exchanges may be different than those of futures exchanges in the United States, and, because initial and variation margin payments may be measured in foreign currency, a futures contract traded outside the United States may also involve the risk of foreign currency fluctuations.

**Swaps** — A swap is an agreement pursuant to which two parties agree to exchange the returns, or differential in rates of returns, earned or realized on particular predetermined interest rates, investments or instruments over a predetermined period. The gross returns to be exchanged or

American Funds Insurance Series – Managed Risk Funds — Page 8

------

'swapped' between the parties are calculated with respect to a notional amount — for example, the return on or increase in value of a particular dollar amount invested at a particular interest rate. The notional amount of the swap is only used to calculate the amount of the obligations the parties to a swap have agreed to exchange. The fund's obligations or rights under a swap will be equal only to the amount to be paid or received under the agreement based on the relative values of the positions held by each party to the agreement, and not the notional amount. For exchange-traded swaps, the fund would be under the same obligations to post initial and variation margin as with exchange-traded futures. However, the amount of initial and variation margin is generally set by the exchanges on which the contracts are traded, so the amount of any such margin could be more or less than the amount required for exchange-traded futures. Additionally, for exchange-traded swaps, the fund would be under the same obligations as both exchange-traded options and exchange-traded futures to segregate assets, though the value of assets to be segregated for each instrument type may vary.

Currently the swaps market is largely an over-the-counter market with swaps made directly between two counterparties. The fund does not intend to use over-the-counter swaps. However, current government regulation is intended to move a substantial portion of the market for swaps to an exchange-traded swaps market. If, in the judgment of the fund's investment adviser and the subadviser, the exchange-traded swaps market becomes similar in depth and substance to that of the exchange-traded futures market, the subadviser may use exchange-traded swaps to seek to hedge interest rate risk. In such a market the operational aspects and risks of investing in exchange-traded swaps will be substantially similar to those of investing in exchange-traded futures.

**Short positions —** The fund may take short positions in exchange-traded futures contracts or other investments to attempt to offset potential declines in the value of securities held by the underlying fund. The subadviser selects individual futures contracts on equity indexes of U.S. markets and markets outside the United States that it believes are correlated to the underlying fund's equity exposure. A short position in a futures contract is a transaction in which the fund enters into a futures contract or other investment in anticipation that the market price of that futures contract or other investment will decline due to a decline in the underlying index.

If the price of the futures contract or other investment "sold" short increases between the time the short position in the futures contract is entered and the time the fund closes out its short position in the futures contract with a corresponding long position in a futures contract for the same underlying index or the futures contract expires, the fund will incur a loss. Since the value of the underlying equity index to a futures contract or other investment could theoretically continually increase the amount of losses are potentially unlimited. If the price of the futures contract or other investment sold declines between the time the short position in the futures contract is entered and the time the fund closes out its short position in the futures contract with a corresponding long position in a futures contract for the same underlying index or the futures contract expires, the fund will realize a gain. The successful use of short positions by the fund may be adversely affected by imperfect correlation between the securities of the underlying fund being hedged and the underlying indexes of the futures contracts.

**Cash and cash equivalents —** The fund may hold cash or invest in cash equivalents. Cash equivalents include, but are not limited to: (*a*) commercial paper; (*b*) short-term bank obligations (for example, certificates of deposit, bankers' acceptances (time drafts on a commercial bank where the bank accepts an irrevocable obligation to pay at maturity)) or bank notes; (*c*) savings association and savings bank obligations (for example, bank notes and certificates of deposit issued by savings banks or savings associations); (*d*) securities of the U.S. government, its agencies or instrumentalities that mature, or that may be redeemed, in one year or less; (*e*) higher quality corporate bonds and notes that mature, or that may be redeemed, in one year or less; and (*f*) shares of money market funds. The fund may hold shares of money market funds in its cash position that are advised by the fund's investment adviser and/or by an affiliate of the fund's custodian.

American Funds Insurance Series – Managed Risk Funds — Page 9

------

There is no limit on the extent to which the fund may take temporary defensive measures. In taking such measures, the fund may fail to achieve its investment objective.

**Commercial paper —** The fund may purchase commercial paper. Commercial paper refers to short-term promissory notes issued by a corporation to finance its current operations. Such securities normally have maturities of thirteen months or less and, though commercial paper is often unsecured, commercial paper may be supported by letters of credit, surety bonds or other forms of collateral. Maturing commercial paper issuances are usually repaid by the issuer from the proceeds of new commercial paper issuances. As a result, investment in commercial paper is subject to rollover risk, or the risk that the issuer cannot issue enough new commercial paper to satisfy its outstanding commercial paper. Like all fixed income securities, commercial paper prices are susceptible to fluctuations in interest rates. If interest rates rise, commercial paper prices will decline and vice versa. However, the short-term nature of a commercial paper investment makes it less susceptible to volatility than many other fixed income securities because interest rate risk typically increases as maturity lengths increase. Commercial paper tends to yield smaller returns than longer-term corporate debt because securities with shorter maturities typically have lower effective yields than those with longer maturities. As with all fixed income securities, there is a chance that the issuer will default on its commercial paper obligations and commercial paper may become illiquid or suffer from reduced liquidity in these or other situations.

Commercial paper in which the fund may invest includes commercial paper issued in reliance on the exemption from registration afforded by Section 4(a)(2) of the Securities Act of 1933, as amended (the "1933 Act"). Section 4(a)(2) commercial paper has substantially the same price and liquidity characteristics as commercial paper generally, except that the resale of Section 4(a)(2) commercial paper is limited to institutional investors who agree that they are purchasing the paper for investment purposes and not with a view to public distribution. Technically, such a restriction on resale renders Section 4(a)(2) commercial paper a restricted security under the 1933 Act. In practice, however, Section 4(a)(2) commercial paper typically can be resold as easily as any other unrestricted security held by the fund. Accordingly, Section 4(a)(2) commercial paper has been generally determined to be liquid under procedures adopted by the fund's board of trustees.

**Regulatory considerations —** The investment adviser has registered with the Commodity Futures Trading Commission ("CFTC") as a commodity pool operator (CPO). As a CPO, the investment adviser has adopted certain policies and procedures and implemented certain operational aspects of the fund in order to be in compliance with CFTC rules and regulations. The investment adviser has claimed the relief necessary to take advantage of the CFTC's approach of permitting substituted compliance with SEC rule requirements, which allows the investment adviser to satisfy applicable CFTC rule requirements by complying with certain SEC rule requirements. As a registered CPO, the investment adviser is subject to additional requirements that are not addressed by substituted compliance with SEC rules. Compliance with these additional registration and regulatory requirements may increase the fund's expenses.

**Cybersecurity risks —** With the increased use of technologies such as the Internet to conduct business, the fund and the underlying fund have become potentially more susceptible to operational and information security risks through breaches in cybersecurity. In general, a breach in cybersecurity can result from either a deliberate attack or an unintentional event. Cybersecurity breaches may involve, among other things, "ransomware" attacks, injection of computer viruses or malicious software code, or the use of vulnerabilities in code to gain unauthorized access to digital information systems, networks or devices that are used directly or indirectly by the fund or its service providers through "hacking" or other means. Cybersecurity risks also include the risk of losses of service resulting from external attacks that do not require unauthorized access to a fund's systems, networks or devices. For example, denial-of-service attacks on the investment adviser's or an affiliate's website could effectively render a fund's network services unavailable to fund shareholders and other intended end-users. Any such cybersecurity breaches or losses of service may, among other things, cause a fund to lose

proprietary information, suffer data corruption or lose operational capacity, or may result in the misappropriation, unauthorized release or other misuse of a fund's assets or sensitive information (including shareholder personal information or other confidential information), the inability of fund shareholders to transact business, or the destruction of a fund's physical infrastructure, equipment or operating systems. These, in turn, could cause the fund to violate applicable privacy and other laws and incur or suffer regulatory penalties, reputational damage, additional costs (including compliance costs) associated with corrective measures and/or financial loss. While the fund, the underlying fund and their investment adviser have established business continuity plans and risk management systems designed to prevent or reduce the impact of cybersecurity attacks, there are inherent limitations in such plans and systems due in part to the ever-changing nature of technology and cybersecurity attack tactics, and there is a possibility that certain risks have not been adequately identified or prepared for.

In addition, cybersecurity failures by or breaches of the fund's or the underlying fund's third-party service providers (including, but not limited to, a fund's investment adviser, subadviser, transfer agent, custodian, administrators and other financial intermediaries, as applicable) may disrupt the business operations of the service providers and of the fund, potentially resulting in financial losses, the inability of fund shareholders to transact business with the fund and of the fund to process transactions, the inability of the fund to calculate its net asset value, violations of applicable privacy and other laws, rules and regulations, regulatory fines, penalties, reputational damage, reimbursement or other compensatory costs and/or additional compliance costs associated with implementation of any corrective measures. The fund, the underlying fund and their respective shareholders could be negatively impacted as a result of any such cybersecurity breaches, and there can be no assurance that a fund will not suffer losses relating to cybersecurity attacks or other informational security breaches affecting the fund's third-party service providers in the future, particularly as a fund cannot control any cybersecurity plans or systems implemented by such service providers.

Cybersecurity risks may also impact issuers of securities in which the underlying fund invests, which may cause the underlying fund's investments in such issuers to lose value.

#### The underlying funds
The following descriptions of securities and techniques apply to the Growth Fund, the International Fund, Washington Mutual Investors Fund, the Growth-Income Fund, The Bond Fund of America, the Government Fund and/or the Asset Allocation Fund (collectively, the "underlying funds"). Except where the context indicates otherwise, all references herein to the "underlying fund" apply to each of the underlying funds. However, because the following is a combined summary of investment strategies of all of the underlying funds, certain matters described herein will only apply to a fund to the extent such fund is invested in an underlying fund that engages in such a strategy.

**Market conditions –** The value of, and the income generated by, the securities in which the underlying fund invests may decline, sometimes rapidly or unpredictably, due to factors affecting certain issuers, particular industries or sectors, or the overall markets. Rapid or unexpected changes in market conditions could cause the underlying fund to liquidate holdings at inopportune times or at a loss or depressed value. The value of a particular holding may decrease due to developments related to that issuer, but also due to general market conditions, including real or perceived economic developments such as changes in interest rates, credit quality, inflation, or currency rates or generally adverse investor sentiment, or political events, such as the imposition of trading and tariff arrangements. The value of a holding may also decline due to factors that negatively affect a particular industry or sector, such as labor shortages, increased production costs, or competitive conditions.

Global economies and financial markets are highly interconnected, and conditions and events in one country, region or financial market may adversely impact issuers in a different country, region or financial market. Furthermore, local, regional and global events such as war, acts of terrorism, trading

American Funds Insurance Series – Managed Risk Funds — Page 11

------

and tariff arrangements, social unrest, natural disasters, the spread of infectious illness or other public health threats, or bank failures could also adversely impact issuers, markets and economies, including in ways that cannot necessarily be foreseen. The underlying fund could be negatively impacted if the value of a portfolio holding were harmed by such conditions or events.

Significant market disruptions, such as those caused by pandemics, natural or environmental disasters, war, acts of terrorism, bank failures or other events, can adversely affect local and global markets and normal market operations. Market disruptions may exacerbate political, social, and economic risks. Additionally, market disruptions may result in increased market volatility; regulatory trading halts; closure of domestic or foreign exchanges, markets, or governments; or market participants operating pursuant to business continuity plans for indeterminate periods of time. Such events can be highly disruptive to economies and markets and significantly impact individual companies, sectors, industries, markets, currencies, interest and inflation rates, credit ratings, investor sentiment, and other factors affecting the value of the fund's investments and operation of the fund. These events could disrupt businesses that are integral to the fund's operations or impair the ability of employees of fund service providers to perform essential tasks on behalf of the fund.

Governmental and quasi-governmental authorities may take a number of actions designed to support local and global economies and the financial markets in response to economic disruptions. Such actions may include a variety of significant fiscal and monetary policy changes, including, for example, direct capital infusions into companies, new monetary programs and significantly lower interest rates. These actions have resulted in significant expansion of public debt and may result in greater market risk. Additionally, an unexpected or quick reversal of these policies, or the ineffectiveness of these policies, could negatively impact overall investor sentiment and further increase volatility in securities markets.

**Equity securities —** The underlying fund may invest in equity securities. Equity securities represent an ownership position in a company. Equity securities held by the underlying fund typically consist of common stocks. The prices of equity securities fluctuate based on, among other things, events specific to their issuers and market, economic and other conditions. For example, prices of these securities can be affected by financial contracts held by the issuer or third parties (such as derivatives) relating to the security or other assets or indices. Holders of equity securities are not creditors of the issuer. If an issuer liquidates, holders of equity securities are entitled to their pro rata share of the issuer's assets, if any, after creditors (including the holders of fixed income securities and senior equity securities) are paid.

There may be little trading in the secondary market for particular equity securities, which may adversely affect the underlying fund's ability to value accurately or dispose of such equity securities. Adverse publicity and investor perceptions, whether or not based on fundamental analysis, may decrease the value and/or liquidity of equity securities.

The growth-oriented, equity-type securities generally purchased by the underlying fund may involve large price swings and potential for loss. To the extent the underlying fund invests in income-oriented, equity-type securities, income provided by the underlying fund may be reduced by changes in the dividend policies of, and the capital resources available at, the companies in which the underlying fund invests.

**Debt instruments —** Debt securities, also known as "fixed income securities," are used by issuers to borrow money. Bonds, notes, debentures, asset-backed securities (including those backed by mortgages), and loan participations and assignments are common types of debt securities. Generally, issuers pay investors periodic interest and repay the amount borrowed either periodically during the life of the security and/or at maturity. Some debt securities, such as zero coupon bonds, do not pay current interest, but are purchased at a discount from their face values and their values accrete over

American Funds Insurance Series – Managed Risk Funds — Page 12

------

time to face value at maturity. Some debt securities bear interest at rates that are not fixed, but that vary with changes in specified market rates or indices. The market prices of debt securities fluctuate depending on such factors as interest rates, credit quality and maturity. In general, market prices of debt securities decline when interest rates rise and increase when interest rates fall. These fluctuations will generally be greater for longer-term debt securities than for shorter-term debt securities. Prices of these securities can also be affected by financial contracts held by the issuer or third parties (such as derivatives) relating to the security or other assets or indices. Borrowers that are in bankruptcy or restructuring may never pay off their indebtedness, or they may pay only a small fraction of the amount owed. Direct indebtedness of countries, particularly emerging markets, also involves a risk that the governmental entities responsible for the repayment of the debt may be unable, or unwilling, to pay interest and repay principal when due.

Lower rated debt securities, rated Ba1/BB+ or below by Nationally Recognized Statistical Rating Organizations, are described by the rating agencies as speculative and involve greater risk of default or price changes due to changes in the issuer's creditworthiness than higher rated debt securities, or they may already be in default. Such securities are sometimes referred to as "junk bonds" or high yield bonds. The market prices of these securities may fluctuate more than higher quality securities and may decline significantly in periods of general economic difficulty. It may be more difficult to dispose of, and to determine the value of, lower rated debt securities. Investment grade bonds in the ratings categories A or Baa/BBB also may be more susceptible to changes in market or economic conditions than bonds rated in the highest rating categories.

Certain additional risk factors relating to debt securities are discussed below:

**Sensitivity to interest rate and economic changes —** Debt securities may be sensitive to economic changes, political and corporate developments, and interest rate changes. In addition, during an economic downturn or a period of rising interest rates, issuers that are highly leveraged may experience increased financial stress that could adversely affect their ability to meet projected business goals, to obtain additional financing and to service their principal and interest payment obligations. Periods of economic change and uncertainty also can be expected to result in increased volatility of market prices and yields of certain debt securities and derivative instruments. As discussed under "Market conditions" above in this statement of additional information, governments and quasi-governmental authorities may take actions to support local and global economies and financial markets during periods of economic crisis, including direct capital infusions into companies, new monetary programs and significantly lower interest rates. Such actions may expose fixed income markets to heightened volatility and may reduce liquidity for certain investments, which could cause the value of the underlying fund's portfolio to decline.

**Payment expectations —** Debt securities may contain redemption or call provisions. If an issuer exercises these provisions in a lower interest rate market, the underlying fund may have to replace the security with a lower yielding security, resulting in decreased income to investors. If the issuer of a debt security defaults on its obligations to pay interest or principal or is the subject of bankruptcy proceedings, the underlying fund may incur losses or expenses in seeking recovery of amounts owed to it.

**Liquidity and valuation —** There may be little trading in the secondary market for particular debt securities, which may affect adversely the underlying fund's ability to value accurately or dispose of such debt securities. Adverse publicity and investor perceptions, whether or not based on fundamental analysis, may decrease the value and/or liquidity of debt securities.

Credit ratings for debt securities provided by rating agencies reflect an evaluation of the safety of principal and interest payments, not market value risk. The rating of an issuer is a rating agency's view

American Funds Insurance Series – Managed Risk Funds — Page 13

------

of past and future potential developments related to the issuer and may not necessarily reflect actual outcomes. There can be a lag between the time of developments relating to an issuer and the time a rating is assigned and updated. The investment adviser considers these ratings of securities as one of many criteria in making its investment decisions.

Bond rating agencies may assign modifiers (such as +/–) to ratings categories to signify the relative position of a credit within the rating category. Investment policies that are based on ratings categories should be read to include any security within that category, without giving consideration to the modifier except where otherwise provided. See the appendix to this statement of additional information for more information about credit ratings.

**Securities with equity and debt characteristics —** Certain securities have a combination of equity and debt characteristics. Such securities may at times behave more like equity than debt or vice versa.

**Preferred stock** — Preferred stock represents an equity interest in an issuer that generally entitles the holder to receive, in preference to common stockholders and the holders of certain other stocks, dividends and a fixed share of the proceeds resulting from a liquidation of the issuer. Preferred stocks may pay fixed or adjustable rates of return, and preferred stock dividends may be cumulative or non-cumulative and participating or non-participating. Cumulative dividend provisions require all or a portion of prior unpaid dividends to be paid before dividends can be paid to the issuer's common stockholders, while prior unpaid dividends on non-cumulative preferred stock are forfeited. Participating preferred stock may be entitled to a dividend exceeding the issuer's declared dividend in certain cases, while non-participating preferred stock is entitled only to the stipulated dividend. Preferred stock is subject to issuer-specific and market risks applicable generally to equity securities. As with debt securities, the prices and yields of preferred stocks often move with changes in interest rates and the issuer's credit quality. Additionally, a company's preferred stock typically pays dividends only after the company makes required payments to holders of its bonds and other debt. Accordingly, the price of preferred stock will usually react more strongly than bonds and other debt to actual or perceived changes in the issuing company's financial condition or prospects. Preferred stock of smaller companies may be more vulnerable to adverse developments than preferred stock of larger companies.

**Convertible securities** — A convertible security is a debt obligation, preferred stock or other security that may be converted, within a specified period of time and at a stated conversion rate, into common stock or other equity securities of the same or a different issuer. The conversion may occur automatically upon the occurrence of a predetermined event or at the option of either the issuer or the security holder. Under certain circumstances, a convertible security may also be called for redemption or conversion by the issuer after a particular date and at predetermined price specified upon issue. If a convertible security held by an underlying fund is called for redemption or conversion, the fund could be required to tender the security for redemption, convert it into the underlying common stock, or sell it to a third party.

The holder of a convertible security is generally entitled to participate in the capital appreciation resulting from a market price increase in the issuer's common stock and to receive interest paid or accrued until the convertible security matures or is redeemed, converted or exchanged. Before conversion, convertible securities have characteristics similar to non-convertible debt or preferred securities, as applicable. Convertible securities rank senior to common stock in an issuer's capital structure and, therefore, normally entail less risk than the issuer's common stock. However, convertible securities may also be subordinate to any senior debt obligations of the issuer, and, therefore, an issuer's convertible securities may entail more risk than such senior debt obligations. Convertible securities usually offer lower interest or dividend yields than non-convertible debt securities of similar credit quality because

American Funds Insurance Series – Managed Risk Funds — Page 14

------

of the potential for capital appreciation. In addition, convertible securities are often lower-rated securities.

Because of the conversion feature, the price of a convertible security will normally fluctuate in some proportion to changes in the price of the underlying asset, and, accordingly, convertible securities are subject to risks relating to the activities of the issuer and/or general market and economic conditions. The income component of a convertible security may cushion the security against declines in the price of the underlying asset but may also cause the price of the security to fluctuate based upon changes in interest rates and the credit quality of the issuer. As with a straight fixed income security, the price of a convertible security tends to increase when interest rates decline and decrease when interest rates rise. Like the price of a common stock, the price of a convertible security also tends to increase as the price of the underlying stock rises and to decrease as the price of the underlying stock declines.

**Hybrid securities** — A hybrid security is a type of security that also has equity and debt characteristics. Like equities, which have no final maturity, a hybrid security may be perpetual. On the other hand, like debt securities, a hybrid security may be callable at the option of the issuer on a date specified at issue. Additionally, like common equities, which may stop paying dividends at virtually any time without violating any contractual terms or conditions, hybrids typically allow for issuers to withhold payment of interest until a later date or to suspend coupon payments entirely without triggering an event of default. Hybrid securities are normally at the bottom of an issuer's debt capital structure because holders of an issuer's hybrid securities are structurally subordinated to the issuer's senior creditors. In bankruptcy, hybrid security holders should only get paid after all senior creditors of the issuer have been paid but before any disbursements are made to the issuer's equity holders. Accordingly, hybrid securities may be more sensitive to economic changes than more senior debt securities. Such securities may also be viewed as more equity-like by the market when the issuer or its parent company experiences financial difficulties.

Contingent convertible securities, which are also known as contingent capital securities, are a form of hybrid security that are intended to either convert into equity or have their principal written down upon the occurrence of certain trigger events. One type of contingent convertible security has characteristics designed to absorb losses, by providing that the liquidation value of the security may be adjusted downward to below the original par value or written off entirely under certain circumstances. For instance, if losses have eroded the issuer's capital level below a specified threshold, the liquidation value of the security may be reduced in whole or in part. The write-down of the security's par value may occur automatically and would not entitle holders to institute bankruptcy proceedings against the issuer. In addition, an automatic write-down could result in a reduced income rate if the dividend or interest payment associated with the security is based on the security's par value. Such securities may, but are not required to, provide for circumstances under which the liquidation value of the security may be adjusted back up to par, such as an improvement in capitalization or earnings. Another type of contingent convertible security provides for mandatory conversion of the security into common shares of the issuer under certain circumstances. The mandatory conversion might relate, for example, to the issuer's failure to maintain a capital minimum. Since the common stock of the issuer may not pay a dividend, investors in such instruments could experience reduced yields (or no yields at all) and conversion would deepen the subordination of the investor, effectively worsening the investor's standing in the case of the issuer's insolvency. An automatic write-down or conversion event with respect to a contingent convertible security will typically be triggered by a reduction in the issuer's capital level, but may also be triggered by regulatory actions, such as a change in regulatory capital requirements, or by other factors.

**Investing in smaller capitalization stocks —** The underlying fund may invest in the stocks of smaller capitalization companies. Investing in smaller capitalization stocks can involve greater risk than is

American Funds Insurance Series – Managed Risk Funds — Page 15

------

customarily associated with investing in stocks of larger, more established companies. For example, smaller companies often have limited product lines, limited operating histories, limited markets or financial resources, may be dependent on one or a few key persons for management and can be more susceptible to losses. Also, their securities may be less liquid or illiquid (and therefore have to be sold at a discount from current prices or sold in small lots over an extended period of time), may be followed by fewer investment research analysts and may be subject to wider price swings, thus creating a greater chance of loss than securities of larger capitalization companies. The underlying fund determines relative market capitalizations using U.S. standards. Accordingly, the underlying fund's investments in certain countries outside the United States may have larger market capitalizations relative to other companies within those countries.

**Investing in private companies —** The underlying fund may invest in companies that have not publicly offered their securities. Investing in private companies can involve greater risks than those associated with investing in publicly traded companies. For example, the securities of a private company may be subject to the risk that market conditions, developments within the company, investor perception, or regulatory decisions may delay or prevent the company from ultimately offering its securities to the public. Furthermore, these investments are generally considered to be illiquid until a company's public offering and are often subject to additional contractual restrictions on resale that would prevent the underlying fund from selling its company shares for a period of time following the public offering.

Investments in private companies can offer the underlying fund significant growth opportunities at attractive prices. However, these investments can pose greater risk, and, consequently, there is no guarantee that positive results can be achieved in the future.

**Investing outside the United States —** Securities of issuers domiciled outside the United States or with significant operations or revenues outside the United States, and securities tied economically to countries outside the United States, may lose value because of adverse political, social, economic or market developments (including social instability, regional conflicts, terrorism and war) in the countries or regions in which the issuers are domiciled, operate or generate revenue or to which the securities are tied economically. These issuers may also be more susceptible to actions of foreign governments such as the imposition of price controls, sanctions, or punitive taxes that could adversely impact the value of these securities. To the extent the underlying fund invests in securities that are denominated in currencies other than the U.S. dollar, these securities may also lose value due to changes in foreign currency exchange rates against the U.S. dollar and/or currencies of other countries. Securities markets in certain countries may be more volatile or less liquid than those in the United States. Investments outside the United States may also be subject to different accounting practices and different regulatory, legal, auditing, financial reporting and recordkeeping standards and practices, and may be more difficult to value, than those in the United States. In addition, the value of investments outside the United States may be reduced by foreign taxes, including foreign withholding taxes on interest and dividends. Further, there may be increased risks of delayed settlement of securities purchased or sold by the underlying fund, which could impact the liquidity of the fund's portfolio. The risks of investing outside the United States may be heightened in connection with investments in emerging markets.

Additional costs could be incurred in connection with the underlying fund's investment activities outside the United States. Brokerage commissions may be higher outside the United States, and the underlying fund will bear certain expenses in connection with its currency transactions. Furthermore, increased custodian costs may be associated with maintaining assets in certain jurisdictions.

**Investing in emerging markets** — Investing in emerging markets may involve risks in addition to and greater than those generally associated with investing in the securities markets of developed countries. For instance, emerging market countries tend to have less developed political, economic and legal systems than those in developed countries. Accordingly, the governments of these countries may be less stable and more likely to intervene in the market economy, for example, by imposing capital controls, nationalizing a company or industry, placing restrictions on foreign ownership and on

American Funds Insurance Series – Managed Risk Funds — Page 16

------

withdrawing sale proceeds of securities from the country, and/or imposing punitive taxes that could adversely affect the prices of securities. Information regarding issuers in emerging markets may be limited, incomplete or inaccurate, and such issuers may not be subject to regulatory, accounting, auditing, and financial reporting and recordkeeping standards comparable to those to which issuers in more developed markets are subject. The underlying fund's rights with respect to its investments in emerging markets, if any, will generally be governed by local law, which may make it difficult or impossible for the underlying fund to pursue legal remedies or to obtain and enforce judgments in local courts. In addition, the economies of these countries may be dependent on relatively few industries, may have limited access to capital and may be more susceptible to changes in local and global trade conditions and downturns in the world economy. Securities markets in these countries can also be relatively small and have substantially lower trading volumes. As a result, securities issued in these countries may be more volatile and less liquid, more vulnerable to market manipulation, and more difficult to value, than securities issued in countries with more developed economies and/or markets. Less certainty with respect to security valuations may lead to additional challenges and risks in calculating the underlying fund's net asset value. Additionally, emerging markets are more likely to experience problems with the clearing and settling of trades and the holding of securities by banks, agents and depositories that are less established than those in developed countries.

In countries where direct foreign investment is limited or prohibited, the underlying fund may invest in operating companies based in such countries through an offshore intermediary entity that, based on contractual agreements, seeks to replicate the rights and obligations of direct equity ownership in such operating company. Because the contractual arrangements do not in fact bestow the underlying fund with actual equity ownership in the operating company, these investment structures may limit the underlying fund's rights as an investor and create significant additional risks. For example, local government authorities may determine that such structures do not comply with applicable laws and regulations, including those relating to restrictions on foreign ownership. In such event, the intermediary entity and/or the operating company may be subject to penalties, revocation of business and operating licenses or forfeiture of foreign ownership interests, and the underlying fund's economic interests in the underlying operating company and its rights as an investor may not be recognized, resulting in a loss to the underlying fund and its shareholders. In addition, exerting control through contractual arrangements may be less effective than direct equity ownership, and a company may incur substantial costs to enforce the terms of such arrangements, including those relating to the distribution of the underlying funds among the entities. These special investment structures may also be disregarded for tax purposes by local tax authorities, resulting in increased tax liabilities, and the underlying fund's control over – and distributions due from – such structures may be jeopardized if the individuals who hold the equity interest in such structures breach the terms of the agreements. While these structures may be widely used to circumvent limits on foreign ownership in certain jurisdictions, there is no assurance that they will be upheld by local regulatory authorities or that disputes regarding the same will be resolved consistently.

Although there is no universally accepted definition, the investment adviser generally considers an emerging market to be a market that is in the earlier stages of its industrialization cycle with a low per capita gross domestic product ("GDP") and a low market capitalization to GDP ratio relative to those in the United States and the European Union, and would include markets commonly referred to as "frontier markets." For example, the investment adviser currently expects that most countries not designated as developed markets by MSCI Inc. ("MSCI") will be treated as emerging markets for equity securities, and that most countries designated as emerging markets by J.P. Morgan or, if not available, Bloomberg will be treated as emerging markets for debt securities.

**Certain risk factors related to emerging markets**

**Currency fluctuations —** Certain emerging markets' currencies have experienced and in the future may experience significant declines against the U.S. dollar. For example, if the U.S. dollar appreciates against foreign currencies, the value of the underlying fund's emerging

American Funds Insurance Series – Managed Risk Funds — Page 17

------

markets securities holdings would generally depreciate and vice versa. Further, the fund may lose money due to losses and other expenses incurred in converting various currencies to purchase and sell securities valued in currencies other than the U.S. dollar, as well as from currency restrictions, exchange control regulation, governmental restrictions that limit or otherwise delay the fund's ability to convert or repatriate currencies and currency devaluations.

**Government regulation —** Certain emerging markets lack uniform accounting, auditing and financial reporting and disclosure standards, have less governmental supervision of financial markets than in the United States, and may not honor legal rights or protections enjoyed by investors in the United States. Certain governments may be more unstable and present greater risks of nationalization or restrictions on foreign ownership of local companies. Repatriation of investment income, capital and the proceeds of sales by foreign investors may require governmental registration and/or approval in some emerging markets. While the underlying fund will only invest in markets where these restrictions are considered acceptable by the investment adviser, a country could impose new or additional repatriation restrictions after the underlying fund's investment. If this happened, the underlying fund's response might include, among other things, applying to the appropriate authorities for a waiver of the restrictions or engaging in transactions in other markets designed to offset the risks of decline in that country. Such restrictions will be considered in relation to the underlying fund's liquidity needs and other factors. Further, some attractive equity securities may not be available to the underlying fund if foreign shareholders already hold the maximum amount legally permissible.

While government involvement in the private sector varies in degree among emerging markets, such involvement may in some cases include government ownership of companies in certain sectors, wage and price controls or imposition of trade barriers and other protectionist measures. With respect to any emerging market, there is no guarantee that some future economic or political crisis will not lead to price controls, forced mergers of companies, expropriation, or creation of government monopolies to the possible detriment of the underlying fund's investments.

**Fluctuations in inflation rates —** Rapid fluctuations in inflation rates may have negative impacts on the economies and securities markets of certain emerging market countries.

**Less developed securities markets —** Emerging markets may be less well-developed and regulated than other markets. These markets have lower trading volumes than the securities markets of more developed countries and may be unable to respond effectively to increases in trading volume. Consequently, these markets may be substantially less liquid than those of more developed countries, and the securities of issuers located in these markets may have limited marketability. These factors may make prompt liquidation of substantial portfolio holdings difficult or impossible at times.

**Settlement risks —** Settlement systems in emerging markets are generally less well organized than those of developed markets. Supervisory authorities may also be unable to apply standards comparable to those in developed markets. Thus, there may be risks that settlement may be delayed and that cash or securities belonging to the underlying fund may be in jeopardy because of failures of or defects in the systems. In particular, market practice may require that payment be made before receipt of the security being purchased or that delivery of a security be made before payment is received. In such cases, default by a broker or bank (the "counterparty") through which the transaction is effected might cause the underlying fund to suffer a loss. The underlying fund will seek, where possible, to use counterparties whose financial status is such that this risk is reduced. However, there can be no certainty that the underlying fund will be successful in eliminating this risk, particularly as counterparties operating in emerging markets frequently lack the standing or financial resources of those in developed countries. There may also be a danger that, because of uncertainties in the

American Funds Insurance Series – Managed Risk Funds — Page 18

------

operation of settlement systems in individual markets, competing claims may arise with respect to securities held by or to be transferred to the underlying fund.

**Limited market information —** The underlying fund may encounter problems assessing investment opportunities in certain emerging markets in light of limitations on available information and different accounting, auditing and financial reporting standards. For example, due to jurisdictional limitations, the Public Company Accounting Oversight Board ("PCAOB"), which regulates auditors of U.S. reporting companies, may be unable to inspect the audit work and practices of PCAOB-registered auditing firms in certain emerging markets. As a result, there is greater risk that financial records and information relating to an issuer's operations in emerging markets will be incomplete or misleading, which may negatively impact the fund's investments in such company. When faced with limited market information, the underlying fund's investment adviser will seek alternative sources of information, and to the extent the investment adviser is not satisfied with the sufficiency or accuracy of the information obtained with respect to a particular market or security, the underlying fund will not invest in such market or security.

**Taxation —** Taxation of dividends, interest and capital gains received by the underlying fund varies among emerging markets and, in some cases, is comparatively high. In addition, emerging markets typically have less well-defined tax laws and procedures and such laws may permit retroactive taxation so that the underlying fund could become subject in the future to local tax liability that it had not reasonably anticipated in conducting its investment activities or valuing its assets.

**Fraudulent securities —** Securities purchased by the underlying fund may subsequently be found to be fraudulent or counterfeit, resulting in a loss to the underlying fund.

**Remedies —** Emerging markets may offer less protection to investors than U.S. markets and, in the event of investor harm, there may be substantially less recourse available to the underlying fund and its shareholders. In addition, as a matter of law or practicality, the underlying fund and its shareholders - as well as U.S. regulators - may encounter substantial difficulties in obtaining and enforcing judgments and other actions against non-U.S. individuals and companies.

**Investing through Stock Connect —** The underlying fund may invest in China A-shares of certain Chinese companies listed and traded on the Shanghai Stock Exchange ("SSE") and on the Shenzhen Stock Exchange ("SZSE", and together, the "Exchanges") through the Shanghai-Hong Kong Stock Connect Program and the Shenzhen-Hong Kong Stock Connect Program, respectively (together, "Stock Connect"). Stock Connect is a securities trading and clearing program developed by the Exchange of Hong Kong, the Exchanges and the China Securities Depository and Clearing Corporation Limited. Stock Connect facilitates foreign investment in the People's Republic of China ("PRC") via brokers in Hong Kong. Persons investing through Stock Connect are subject to PRC regulations and Exchange listing rules, among others. These could include limitations on or suspension of trading. These regulations are relatively new and subject to changes which could adversely impact the underlying fund's rights with respect to the securities. For example, a stock may be recalled from the scope of securities traded on the SSE or SZSE eligible for trading via Stock Connect for various reasons, and in such event the stock can be sold but is restricted from being bought. In such event, the investment adviser's ability to implement the underlying fund's investment strategies may be adversely affected. As Stock Connect is still relatively new, investments made through Stock Connect are subject to relatively new trading, clearance and settlement procedures and there are no assurances that the necessary systems to run the program will function properly. In addition, Stock Connect is subject to aggregate and daily quota limitations on purchases and permitted price fluctuations. As a result, the underlying fund may experience delays in transacting via Stock Connect and there can be no assurance that a liquid market on the Exchanges will exist. Since

American Funds Insurance Series – Managed Risk Funds — Page 19

------

Stock Connect only operates on days when both the Chinese and Hong Kong markets are open for trading, and banking services are available in both markets on the corresponding settlement days, the underlying fund's ownership interest in securities traded through Stock Connect may not be reflected directly and the underlying fund may be subject to the risk of price fluctuations in China A-shares when Stock Connect is not open to trading. Changes in Chinese tax rules may also adversely affect the underlying fund's performance. The underlying fund's shares are held in an omnibus account and registered in nominee name. Please also see the sections on risks relating to investing outside the United States and investing in emerging markets.

**Investing through Bond Connect —** The underlying fund may invest in onshore China bonds via Bond Connect, the opening up of China's Interbank Bond Market (CIBM) to global investors through the China-Hong Kong mutual access program. The program allows foreign and mainland China investors the ability to trade in each other's bond market through a connection between the mainland and Hong Kong based financial infrastructure institutions. Bond Connect aims to enhance the efficiency and flexibility of investing in the CIBM. This is accomplished by easing the access requirements to enter the market and using the Hong Kong trading infrastructure to connect to China Foreign Exchange Trading System (CFETS). Market volatility and potential lack of liquidity due to low trading volume of certain debt securities in CIBM may result in prices of certain debt securities traded on such market fluctuating significantly. The bid and offer spreads of the prices of such securities may be large, and the underlying fund may therefore incur significant trading, settlement and realization costs and may face counterparty default, liquidity, and volatility risks, resulting in significant losses for the underlying funds and their investors. Bond Connect is a novel concept and, as such, the current regulations are untested and there is no certainty as to how they will be applied. In addition, the current regulations are subject to change which may have potential retrospective effects and there can be no assurance that Bond Connect will not be abolished. New regulations may be issued from time to time by the regulators in the PRC and Hong Kong in connection with operations, legal enforcement and cross-border trades under Bond Connect. The underlying fund may be adversely affected as a result of such changes.

**Currency transactions —** The underlying fund may enter into currency transactions on a spot (i.e., cash) basis at the prevailing rate in the currency exchange market to provide for the purchase or sale of a currency needed to purchase a security denominated in such currency. In addition, the underlying fund may enter into forward currency contracts and may purchase and sell options on currencies to protect against changes in currency exchange rates, to increase exposure to a particular foreign currency, to shift exposure to currency fluctuations from one currency to another or to seek to increase returns. A forward currency contract is an obligation to purchase or sell a specific currency at a future date, which may be any fixed number of days from the date of the contract agreed upon by the parties, at a price set at the time of the contract. Some forward currency contracts, called non-deliverable forwards or NDFs, do not call for physical delivery of the currency and are instead settled through cash payments. Forward currency contracts are typically privately negotiated and traded in the interbank market between large commercial banks (or other currency traders) and their customers. Although forward contracts entered into by the underlying fund will typically involve the purchase or sale of a currency against the U.S. dollar, the underlying fund also may purchase or sell a non-U.S. currency against another non-U.S. currency.

The underlying fund may also purchase or write put and call options on foreign currencies on exchanges or in the over-the-counter ("OTC") market. A put option on a foreign currency gives the purchaser of the option the right to sell a foreign currency at the exercise price until the option expires. A call option on a foreign currency gives the purchaser of the option the right to purchase the currency at the exercise price until the option expires. Currency options, to the extent not exercised, will expire and the underlying fund, as the purchaser, would experience a loss to the extent of the premium paid for the option. Instead of purchasing a call option to hedge against an anticipated increase in the dollar cost of securities to be acquired, the underlying fund could write a put option on the relevant currency, which, if exchange rates move in the manner projected, will expire unexercised and allow the underlying fund to hedge such increased cost up to the amount of the premium. As in the case of

American Funds Insurance Series – Managed Risk Funds — Page 20

other types of options, however, writing a currency option will provide a hedge only up to the amount of the premium, and only if exchange rates move in the expected direction. If this does not occur, the option may be exercised and the underlying fund would be required to purchase or sell the underlying currency at a loss that may not be offset by the amount of the premium. Through the writing of options on foreign currencies, the underlying fund also may be required to forego all or a portion of the benefit that might otherwise have been obtained from favorable movements in exchange rates. OTC options are bilateral contracts that are individually negotiated and they are generally less liquid than exchange-traded options. Although this type of arrangement allows the purchaser or writer greater flexibility to tailor an option to its needs, OTC options generally involve credit risk to the counterparty, whereas for exchange-traded options, credit risk is mutualized through the involvement of the applicable clearing house. Currency options traded on exchanges may be subject to position limits, which may limit the ability of the underlying fund to reduce currency risk using such options. To the extent that the U.S. options markets are closed while the markets for the underlying currencies remain open, substantial price and rate movements may take place in the currency markets that cannot be reflected in the U.S. options markets. See also "Options" for a general description of investment techniques and risks relating to options.

Currency exchange rates generally are determined by forces of supply and demand in the foreign exchange markets and the relative merits of investment in different countries as viewed from an international perspective. Currency exchange rates, as well as foreign currency transactions, can also be affected unpredictably by intervention by U.S. or foreign governments or central banks or by currency controls or political developments in the United States or abroad. Such intervention or other events could prevent the underlying fund from entering into foreign currency transactions, force the underlying fund to exit such transactions at an unfavorable time or price or result in penalties to the underlying fund, any of which may result in losses to the underlying fund.

Generally, the underlying fund will not attempt to protect against all potential changes in exchange rates and the use of forward contracts does not eliminate the risk of fluctuations in the prices of the underlying securities. If the value of the underlying securities declines or the amount of the underlying fund's commitment increases because of changes in exchange rates, the underlying fund may need to provide additional cash or securities to satisfy its commitment under the forward contract. The underlying fund is also subject to the risk that it may be delayed or prevented from obtaining payments owed to it under the forward contract as a result of the insolvency or bankruptcy of the counterparty with which it entered into the forward contract or the failure of the counterparty to comply with the terms of the contract.

The realization of gains or losses on foreign currency transactions will usually be a function of the investment adviser's ability to accurately estimate currency market movements. Entering into forward currency transactions may change the underlying fund's exposure to currency exchange rates and could result in losses to the underlying fund if currencies do not perform as expected by the underlying fund's investment adviser. For example, if the underlying fund's investment adviser increases a fund's exposure to a foreign currency using forward contracts and that foreign currency's value declines, that fund may incur a loss. In addition, while entering into forward currency transactions could minimize the risk of loss due to a decline in the value of the hedged currency, it could also limit any potential gain that may result from an increase in the value of the currency. See also the "Derivatives" section under "Description of certain securities, investment techniques and risks" for a general description of investment techniques and risks relating to derivatives, including certain currency forwards and currency options.

Forward currency contracts may give rise to leverage, or exposure to potential gains and losses in excess of the initial amount invested. Leverage magnifies gains and losses and could cause the fund or the underlying fund to be subject to more volatility than if it had not been leveraged, thereby resulting in a heightened risk of loss. Forward currency contracts are considered derivatives. Accordingly, under the SEC's rule applicable to the underlying fund's use of derivatives, the underlying fund's obligations

American Funds Insurance Series – Managed Risk Funds — Page 21

------

with respect to these instruments will depend on the underlying fund's aggregate usage of and exposure to derivatives, and the underlying fund's usage of forward currency contracts is subject to written policies and procedures reasonably designed to manage the underlying fund's derivatives risk.

Forward currency transactions also may affect the character and timing of income, gain, or loss recognized by the fund or an underlying fund for U.S. tax purposes. The use of forward currency contracts could result in the application of the mark-to-market provisions of the Internal Revenue Code of 1986, as amended (the "Code") and may cause an increase (or decrease) in the amount of taxable dividends paid by the fund or an underlying fund.

**Indirect exposure to cryptocurrencies –** Cryptocurrencies are digital assets which may act as a store of wealth, a medium of exchange or an investment asset. There are thousands of cryptocurrencies, such as bitcoin. Although the underlying fund has no current intention of directly investing in cryptocurrencies, some issuers accept cryptocurrency for payment of services, use cryptocurrencies as reserve assets and/or invest in cryptocurrencies, and the underlying fund may have exposure to cryptocurrencies through investments in securities of such issuers. The underlying fund may also invest in securities of issuers which provide cryptocurrency-related services.

Cryptocurrencies are subject to fluctuations in value. Cryptocurrencies are not backed by any government, corporation or other identified body. Rather, the value of a cryptocurrency is determined by other factors, such as the perceived future prospects or the supply and demand for such cryptocurrency in the global market for the trading of cryptocurrency. Cryptocurrencies may trade on platforms which are largely unregulated and may be more exposed to operational or technical issues as well as fraud or manipulation in comparison to established, regulated exchanges for securities, derivatives and traditional currencies. The values of cryptocurrencies have been, and may in the future continue to be, highly volatile and subject to sudden and significant increases and declines. The value of a cryptocurrency may decline precipitously (including to zero) for a variety of reasons, including, but not limited to, regulatory changes, a loss of confidence in its network or a change in user preference to other cryptocurrencies. The value of securities of issuers with significant holdings of cryptocurrencies may be subject to, among other things, fluctuations in the value of such cryptocurrencies, and such issuers may experience custody issues and/or lose their cryptocurrency holdings through theft, hacking, or technical glitches in the applicable blockchain. The underlying fund may experience losses as a result of the decline in value of its securities of issuers that own cryptocurrencies or which provide cryptocurrency-related services. If an issuer that owns cryptocurrencies intends to pay a dividend using such holdings or to otherwise make a distribution of such holdings to its stockholders, such dividends or distributions may face regulatory, operational and technical issues.

Factors affecting the further development, use, and exchange of cryptocurrency include, but are not limited to: continued worldwide growth of, or possible cessation of or reversal in, the adoption and use of cryptocurrencies and other digital assets; the developing regulatory environment relating to cryptocurrencies, including the characterization of cryptocurrencies as currencies, commodities, or securities, the tax treatment of cryptocurrencies, and government and quasi-government regulation or restrictions on, or regulation of access to and operation of, cryptocurrency networks and the exchanges on which cryptocurrencies trade, including anti-money laundering regulations and requirements; perceptions regarding the environmental impact of a cryptocurrency; changes in consumer demographics and public preferences; general economic conditions; maintenance and development of open-source software protocols; the availability and popularity of other forms or methods of buying and selling goods and services; the use of the networks supporting digital assets, such as those for developing smart contracts and distributed applications; and general risks tied to the use of information technologies, including cyber risks. A hack or failure of one cryptocurrency may lead to a loss in confidence in, and thus decreased usage and/or value of, other cryptocurrencies.

**Forward commitment, when issued and delayed delivery transactions —** The underlying fund may enter into commitments to purchase or sell securities at a future date. When the underlying fund

American Funds Insurance Series – Managed Risk Funds — Page 22

------

agrees to purchase such securities, it assumes the risk of any decline in value of the security from the date of the agreement, and when the underlying fund agrees to sell such securities, it assumes the risk of any increase in value of the security. If the other party to such a transaction fails to deliver or pay for the securities, the underlying fund could miss a favorable price or yield opportunity, or could experience a loss.

The underlying fund may roll such transactions in lieu of taking physical delivery of the contract's underlying assets on the settlement date. When rolling the purchase of these types of transactions, the underlying fund sells mortgage-backed securities for delivery in the current month and simultaneously contracts to repurchase substantially similar (same type, coupon, and maturity) securities on a specified future date, at a pre-determined price. When rolling the sale of these types of transactions, the underlying fund purchases mortgage-backed securities for delivery in the current month and simultaneously contracts to sell substantially similar (same type, coupon, and maturity) securities on a specified future date, at a pre-determined price.

When rolling these types of transactions, during the period between the initial sale (or purchase) and subsequent repurchase (or sale) (the "roll period"), the underlying fund forgoes principal and interest paid on the mortgage-backed securities. The underlying fund is compensated by the price differential between the original and new contracts (often referred to as the "drop"), if any, as well as by the interest earned on the cash proceeds of any sales. The underlying fund also takes the risk that market prices or characteristics of the underlying mortgage-backed securities may move unfavorably between the original and new contracts. The underlying fund could suffer a loss if the contracting party fails to perform the future transaction and the underlying fund is therefore unable to buy or sell back the mortgage-backed securities it initially either sold or purchased, respectively. These transactions are accounted for as purchase and sale transactions, which contribute to the underlying fund's portfolio turnover rate.

With to be announced ("TBA") transactions, the particular securities (i.e., specified mortgage pools) to be delivered or received are not identified at the trade date, but are "to be announced" at a later settlement date. However, securities to be delivered must meet specified criteria, including face value, coupon rate and maturity, and be within industry-accepted "good delivery" standards. The underlying fund will not use these transactions for the purpose of leveraging. Although these transactions will not be entered into for leveraging purposes, the underlying fund temporarily could be in a leveraged position (because it may have an amount greater than its net assets subject to market risk). Should market values of the underlying fund's portfolio securities decline while the underlying fund is in a leveraged position, greater depreciation of its net assets would likely occur than if it were not in such a position. After a transaction is entered into, the underlying fund may still dispose of or renegotiate the transaction. Additionally, prior to receiving delivery of securities as part of a transaction, the underlying fund may sell such securities.

When the underlying fund enters into a TBA commitment for the sale of mortgage-backed securities for a fixed price, with payment and delivery on an agreed upon future settlement date (which may be referred to as having a short position in such TBA securities), the underlying fund may or may not hold the types of mortgage-backed securities required to be delivered. To the extent the underlying fund has sold such a security on a when-issued, delayed delivery, or forward commitment basis, the underlying fund would not participate in future gains or losses with respect to the security if the underlying fund holds such security. If the other party to a transaction fails to pay for the securities, the underlying fund could suffer a loss. Additionally, when selling a security on a when-issued, delayed delivery or forward commitment basis without owning the security, the underlying fund will incur a loss if the security's price appreciates in value such that the security's price is above the agreed-upon price on the settlement date.

Under the SEC's rule applicable to the underlying fund's use of derivatives, when issued, forward-settling and nonstandard settlement cycle securities, as well as TBAs and roll transactions, will be

American Funds Insurance Series – Managed Risk Funds — Page 23

------

treated as derivatives unless the fund intends to physically settle these transactions and the transactions will settle within 35 days of their respective trade dates.

**Obligations backed by the "full faith and credit" of the U.S. government —** U.S. government obligations include the following types of securities:

**U.S. Treasury securities —** U.S. Treasury securities include direct obligations of the U.S. Treasury, such as Treasury bills, notes and bonds. For these securities, the payment of principal and interest is unconditionally guaranteed by the U.S. government, and thus they are of high credit quality.

**Federal agency securities —** The securities of certain U.S. government agencies and government-sponsored entities are guaranteed as to the timely payment of principal and interest by the full faith and credit of the U.S. government. Such agencies and entities include, but are not limited to, the Federal Financing Bank ("FFB"), the Government National Mortgage Association ("Ginnie Mae"), the U.S. Department of Veterans Affairs ("VA"), the Federal Housing Administration ("FHA"), the Export-Import Bank of the United States ("Exim Bank"), the U.S. International Development Finance Corporation ("DFC"), the Commodity Credit Corporation ("CCC") and the U.S. Small Business Administration ("SBA").

Such securities are subject to variations in market value due to fluctuations in interest rates and in government policies, among other things, but, if held to maturity, are expected to be paid in full (either at maturity or thereafter). However, from time to time, a high national debt level, and uncertainty regarding negotiations to increase the U.S. government's debt ceiling and periodic legislation to fund the government, could increase the risk that the U.S. government may default on its obligations and/or lead to a downgrade of the credit rating of the U.S. government. Such an event could adversely affect the value of investments in securities backed by the full faith and credit of the U.S. government, cause the fund to suffer losses and lead to significant disruptions in U.S. and global markets. Regulatory or market changes or conditions could increase demand for U.S. government securities and affect the availability of such instruments for investment and the fund's ability to pursue its investment strategies.

**Other federal agency obligations —** Additional federal agency securities are neither direct obligations of, nor guaranteed by, the U.S. government. These obligations include securities issued by certain U.S. government agencies and government-sponsored entities. However, they generally involve some form of federal sponsorship: some operate under a congressional charter; some are backed by collateral consisting of "full faith and credit" obligations as described above; some are supported by the issuer's right to borrow from the Treasury; and others are supported only by the credit of the issuing government agency or entity. These agencies and entities include, but are not limited to: the Federal Home Loan Banks, the Federal Home Loan Mortgage Corporation ("Freddie Mac"), the Federal National Mortgage Association ("Fannie Mae"), the Tennessee Valley Authority and the Federal Farm Credit Bank System.

In 2008, Freddie Mac and Fannie Mae were placed into conservatorship by their new regulator, the Federal Housing Finance Agency ("FHFA"). Simultaneously, the U.S. Treasury made a commitment of indefinite duration to maintain the positive net worth of both firms. As conservator, the FHFA has the authority to repudiate any contract either firm has entered into prior to the FHFA's appointment as conservator (or receiver should either firm go into default) if the FHFA, in its sole discretion determines that performance of the contract is burdensome and repudiation would promote the orderly administration of Fannie Mae's or Freddie Mac's affairs. While the FHFA has indicated that it does not intend to repudiate the guaranty obligations of either entity, doing so could adversely affect holders of their mortgage-backed securities. For example, if a contract were repudiated, the liability for any direct compensatory damages would accrue to the entity's conservatorship estate and could only be satisfied to the extent the estate had available assets. As a result, if interest payments on Fannie Mae or Freddie

American Funds Insurance Series – Managed Risk Funds — Page 24

------

Mac mortgage-backed securities held by the underlying fund were reduced because underlying borrowers failed to make payments or such payments were not advanced by a loan servicer, the underlying fund's only recourse might be against the conservatorship estate, which might not have sufficient assets to offset any shortfalls.

The FHFA, in its capacity as conservator, has the power to transfer or sell any asset or liability of Fannie Mae or Freddie Mac. The FHFA has indicated it has no current intention to do this; however, should it do so a holder of a Fannie Mae or Freddie Mac mortgage-backed security would have to rely on another party for satisfaction of the guaranty obligations and would be exposed to the credit risk of that party.

Certain rights provided to holders of mortgage-backed securities issued by Fannie Mae or Freddie Mac under their operative documents may not be enforceable against the FHFA, or enforcement may be delayed during the course of the conservatorship or any future receivership. For example, the operative documents may provide that upon the occurrence of an event of default by Fannie Mae or Freddie Mac, holders of a requisite percentage of the mortgage-backed security may replace the entity as trustee. However, under the Federal Housing Finance Regulatory Reform Act of 2008, holders may not enforce this right if the event of default arises solely because a conservator or receiver has been appointed.

**Pass-through securities —** The underlying fund may invest in various debt obligations backed by pools of mortgages, corporate loans or other assets including, but not limited to, residential mortgage loans, home equity loans, mortgages on commercial buildings, consumer loans and equipment leases. Principal and interest payments made on the underlying asset pools backing these obligations are typically passed through to investors, net of any fees paid to any insurer or any guarantor of the securities. Pass-through securities may have either fixed or adjustable coupons. The risks of an investment in these obligations depend in part on the type of the collateral securing the obligations and the class of the instrument in which the fund invests. These securities include:

**Mortgage-backed securities —** These securities may be issued by U.S. government agencies and government-sponsored entities, such as Ginnie Mae, Fannie Mae and Freddie Mac, and by private entities. The payment of interest and principal on mortgage-backed obligations issued by U.S. government agencies may be guaranteed by the full faith and credit of the U.S. government (in the case of Ginnie Mae), or may be guaranteed by the issuer (in the case of Fannie Mae and Freddie Mac). However, these guarantees do not apply to the market prices and yields of these securities, which vary with changes in interest rates.

Mortgage-backed securities issued by private entities are structured similarly to those issued by U.S. government agencies. However, these securities and the underlying mortgages are not guaranteed by any government agencies and the underlying mortgages are not subject to the same underwriting requirements. These securities generally are structured with one or more types of credit enhancements such as insurance or letters of credit issued by private companies. Borrowers on the underlying mortgages are usually permitted to prepay their underlying mortgages. Prepayments can alter the effective maturity of these instruments. In addition, delinquencies, losses or defaults by borrowers can adversely affect the prices and volatility of these securities. Such delinquencies and losses can be exacerbated by declining or flattening housing and property values. This, along with other outside pressures, such as bankruptcies and financial difficulties experienced by mortgage loan originators, decreased investor demand for mortgage loans and mortgage-related securities and increased investor demand for yield, can adversely affect the value and liquidity of mortgage-backed securities.

**Adjustable rate mortgage-backed securities —** Adjustable rate mortgage-backed securities ("ARMS") have interest rates that reset at periodic intervals. Acquiring ARMS permits the

American Funds Insurance Series – Managed Risk Funds — Page 25

------

underlying fund to participate in increases in prevailing current interest rates through periodic adjustments in the coupons of mortgages underlying the pool on which ARMS are based. Such ARMS generally have higher current yield and lower price fluctuations than is the case with more traditional fixed income debt securities of comparable rating and maturity. In addition, when prepayments of principal are made on the underlying mortgages during periods of rising interest rates, the underlying fund can reinvest the proceeds of such prepayments at rates higher than those at which they were previously invested. Mortgages underlying most ARMS, however, have limits on the allowable annual or lifetime increases that can be made in the interest rate that the mortgagor pays. Therefore, if current interest rates rise above such limits over the period of the limitation, the underlying fund, when holding an ARMS, does not benefit from further increases in interest rates. Moreover, when interest rates are in excess of coupon rates (i.e., the rates being paid by mortgagors) of the mortgages, ARMS behave more like fixed income securities and less like adjustable rate securities and are subject to the risks associated with fixed income securities. In addition, during periods of rising interest rates, increases in the coupon rate of adjustable rate mortgages generally lag current market interest rates slightly, thereby creating the potential for capital depreciation on such securities.

**Collateralized mortgage obligations (CMOs) —** CMOs are also backed by a pool of mortgages or mortgage loans, which are divided into two or more separate bond issues. CMOs issued by U.S. government agencies are backed by agency mortgages, while privately issued CMOs may be backed by either government agency mortgages or private mortgages. Payments of principal and interest are passed through to each bond issue at varying schedules resulting in bonds with different coupons, effective maturities and sensitivities to interest rates. Some CMOs may be structured in a way that when interest rates change, the impact of changing prepayment rates on the effective maturities of certain issues of these securities is magnified. CMOs may be less liquid or may exhibit greater price volatility than other types of mortgage or asset-backed securities.

**Commercial mortgage-backed securities —** These securities are backed by mortgages on commercial property, such as hotels, office buildings, retail stores, hospitals and other commercial buildings. These securities may have a lower prepayment uncertainty than other mortgage-related securities because commercial mortgage loans generally prohibit or impose penalties on prepayments of principal. In addition, commercial mortgage-related securities often are structured with some form of credit enhancement to protect against potential losses on the underlying mortgage loans. Many of the risks of investing in commercial mortgage-backed securities reflect the risks of investing in the real estate securing the underlying mortgage loans, including the effects of local and other economic conditions on real estate markets, the ability of tenants to make rental payments and the ability of a property to attract and retain tenants. Commercial mortgage-backed securities may be less liquid or exhibit greater price volatility than other types of mortgage or asset-backed securities and may be more difficult to value.

**Asset-backed securities —** These securities are backed by other assets such as credit card, automobile or consumer loan receivables, retail installment loans or participations in pools of leases. Credit support for these securities may be based on the underlying assets and/or provided through credit enhancements by a third party. The values of these securities are sensitive to changes in the credit quality of the underlying collateral, the credit strength of the credit enhancement, changes in interest rates and at times the financial condition of the issuer. Obligors of the underlying assets also may make prepayments that can change effective maturities of the asset-backed securities. These securities may be less liquid and more difficult to value than other securities.

**Collateralized bond obligations (CBOs) and collateralized loan obligations (CLOs)** — A CBO is a trust typically backed by a diversified pool of fixed-income securities, which may include high

American Funds Insurance Series – Managed Risk Funds — Page 26

------

risk, lower rated securities. A CLO is a trust typically collateralized by a pool of loans, which may include, among others, senior secured loans, senior unsecured loans, and subordinate corporate loans, including lower rated loans. CBOs and CLOs may charge management fees and administrative expenses.

For both CBOs and CLOs, the cash flows from the trust are split into two or more portions, called tranches, varying in risk and yield. The riskiest and highest yielding portion is the "equity" tranche which bears the bulk of any default by the bonds or loans in the trust and is constructed to protect the other, more senior tranches from default. Since they are partially protected from defaults, the more senior tranches typically have higher ratings and lower yields than the underlying securities in the trust and can be rated investment grade. Despite the protection from the equity tranche, the more senior tranches can still experience substantial losses due to actual defaults of the underlying assets, increased sensitivity to defaults due to impairment of the collateral or the more junior tranches, market anticipation of defaults, as well as potential general aversions to CBO or CLO securities as a class. Normally, these securities are privately offered and sold, and thus, are not registered under the securities laws. CBOs and CLOs may be less liquid, may exhibit greater price volatility and may be more difficult to value than other securities.

"IOs" and "POs" are issued in portions or tranches with varying maturities and characteristics. Some tranches may only receive the interest paid on the underlying mortgages (IOs) and others may only receive the principal payments (POs). The values of IOs and POs are extremely sensitive to interest rate fluctuations and prepayment rates, and IOs are also subject to the risk of early repayment of the underlying mortgages that will substantially reduce or eliminate interest payments.

**Warrants and rights —** Warrants and rights may be acquired by certain underlying funds in connection with other securities or separately. Warrants generally entitle, but do not obligate, their holder to purchase other equity or fixed income securities at a specified price at a later date. Rights are similar to warrants but typically have a shorter duration and are issued by a company to existing holders of its stock to provide those holders the right to purchase additional shares of stock at a later date. Warrants and rights do not carry with them the right to dividends or voting rights with respect to the securities that they entitle their holder to purchase, and they do not represent any rights in the assets of the issuing company. Additionally, a warrant or right ceases to have value if it is not exercised prior to its expiration date. As a result, warrants and rights may be considered more speculative than certain other types of investments. Changes in the value of a warrant or right do not necessarily correspond to changes in the value of its underlying security. The price of a warrant or right may be more volatile than the price of its underlying security, and they therefore present greater potential for capital appreciation and capital loss. The effective price paid for warrants or rights added to the subscription price of the related security may exceed the value of the subscribed security's market price, such as when there is no movement in the price of the underlying security. The market for warrants or rights may be very limited and it may be difficult to sell them promptly at an acceptable price.

**Depositary receipts —** Depositary receipts are securities that evidence ownership interests in, and represent the right to receive, a security or a pool of securities that have been deposited with a bank or trust depository. Certain underlying funds may invest in American Depositary Receipts ("ADRs"), European Depositary Receipts ("EDRs"), Global Depositary Receipts ("GDRs"), and other similar securities. For ADRs, the depository is typically a U.S. financial institution and the underlying securities are issued by a non-U.S. entity. For other depositary receipts, the depository may be a non-U.S. or a U.S. entity, and the underlying securities may be issued by a non-U.S. or a U.S. entity. Depositary receipts will not necessarily be denominated in the same currency as their underlying securities. Generally, ADRs are issued in registered form, denominated in U.S. dollars, and designed for use in the U.S. securities markets. Other depositary receipts, such as EDRs and GDRs, may be issued in bearer form, may be denominated in either U.S. dollars or in non-U.S. currencies, and are primarily designed for use in securities markets outside the United States. ADRs, EDRs and GDRs can be

American Funds Insurance Series – Managed Risk Funds — Page 27

------

sponsored by the issuing bank or trust company or the issuer of the underlying securities. Although the issuing bank or trust company may impose charges for the collection of dividends and the conversion of such securities into the underlying securities, generally no fees are imposed on the purchase or sale of these securities other than transaction fees ordinarily involved with trading stock. Such securities may be less liquid or may trade at a lower price than the underlying securities of the issuer. Additionally, the issuers of securities underlying depositary receipts may not be obligated to timely disclose information that is considered material under the securities laws of the United States. Therefore, less information may be available regarding these issuers than about the issuers of other securities and there may not be a correlation between such information and the market value of the depositary receipts.

**Inflation-linked bonds —** The underlying fund may invest in inflation-linked bonds issued by governments, their agencies or instrumentalities and corporations.

The principal amount of an inflation-linked bond is adjusted in response to changes in the level of an inflation index, such as the Consumer Price Index for Urban Consumers ("CPURNSA"). If the index measuring inflation falls, the principal value or coupon of these securities will be adjusted downward. Consequently, the interest payable on these securities will be reduced. Also, if the principal value of these securities is adjusted according to the rate of inflation, the adjusted principal value repaid at maturity may be less than the original principal. In the case of U.S. Treasury Inflation-Protected Securities ("TIPS"), currently the only inflation-linked security that is issued by the U.S. Treasury, the principal amounts are adjusted daily based upon changes in the rate of inflation (as currently represented by the non-seasonally adjusted CPURNSA, calculated with a three-month lag). TIPS may pay interest semi-annually, equal to a fixed percentage of the inflation-adjusted principal amount. The interest rate on these bonds is fixed at issuance, but over the life of the bond this interest may be paid on an increasing or decreasing principal amount that has been adjusted for inflation. The current market value of TIPS is not guaranteed and will fluctuate. However, the U.S. government guarantees that, at maturity, principal will be repaid at the higher of the original face value of the security (in the event of deflation) or the inflation adjusted value.

Other non-U.S. sovereign governments also issue inflation-linked securities that are tied to their own local consumer price indexes and that offer similar deflationary protection. In certain of these non-U.S. jurisdictions, the repayment of the original bond principal upon the maturity of an inflation-linked bond is not guaranteed, allowing for the amount of the bond repaid at maturity to be less than par. Corporations also periodically issue inflation-linked securities tied to CPURNSA or similar inflationary indexes. While TIPS and non-U.S. sovereign inflation-linked securities are currently the largest part of the inflation-linked market, the underlying fund may invest in corporate inflation-linked securities.

The value of inflation-linked securities is expected to change in response to the changes in real interest rates. Real interest rates, in turn, are tied to the relationship between nominal interest rates and the rate of inflation. If inflation were to rise at a faster rate than nominal interest rates, real interest rates would decline, leading to an increase in value of the inflation-linked securities. In contrast, if nominal interest rates were to increase at a faster rate than inflation, real interest rates might rise, leading to a decrease in value of inflation-linked securities. There can be no assurance, however, that the value of inflation-linked securities will be directly correlated to the changes in interest rates. If interest rates rise due to reasons other than inflation, investors in these securities may not be protected to the extent that the increase is not reflected in the security's inflation measure.

The interest rate for inflation-linked bonds is fixed at issuance as a percentage of this adjustable principal. Accordingly, the actual interest income may both rise and fall as the principal amount of the bonds adjusts in response to movements of the consumer price index. For example, typically interest income would rise during a period of inflation and fall during a period of deflation.

American Funds Insurance Series – Managed Risk Funds — Page 28

The market for inflation-linked securities may be less developed or liquid, and more volatile, than certain other securities markets. There is a limited number of inflation-linked securities currently available for the underlying fund to purchase, making the market less liquid and more volatile than the U.S. Treasury and agency markets.

**Real estate investment trusts —** Real estate investment trusts ("REITs"), which primarily invest in real estate or real estate-related loans, may issue equity or debt securities. Equity REITs own real estate properties, while mortgage REITs hold construction, development and/or long-term mortgage loans. The values of REITs may be affected by changes in the value of the underlying property of the trusts, the creditworthiness of the issuer, property taxes, interest rates, tax laws and regulatory requirements, such as those relating to the environment. Both types of REITs are dependent upon management skill and the cash flows generated by their holdings, the real estate market in general and the possibility of failing to qualify for any applicable pass-through tax treatment or failing to maintain any applicable exemptive status afforded under relevant laws.

**Variable and floating rate obligations —** The interest rates payable on certain securities and other instruments in which certain of the underlying funds may invest may not be fixed but may fluctuate based upon changes in market interest rates or credit ratings. Variable and floating rate obligations bear coupon rates that are adjusted at designated intervals, based on the then current market interest rates or credit ratings. The rate adjustment features tend to limit the extent to which the market value of the obligations will fluctuate. When the fund holds variable or floating rate securities, a decrease in market interest rates will adversely affect the income received from such securities and the net asset value of the fund's shares.

**Restricted or illiquid securities —** The underlying fund may purchase securities subject to restrictions on resale. Restricted securities may only be sold pursuant to an exemption from registration under the Securities Act of 1933, as amended (the "1933 Act"), or in a registered public offering. Restricted securities held by the underlying fund are often eligible for resale under Rule 144A, an exemption under the 1933 Act allowing for resales to "Qualified Institutional Buyers." Where registration is required, the holder of a registered security may be obligated to pay all or part of the registration expense and a considerable period may elapse between the time it decides to seek registration and the time it may be permitted to sell a security under an effective registration statement. Difficulty in selling such securities may result in a loss to the underlying fund or cause it to incur additional administrative costs.

Some underlying fund holdings (including some restricted securities) may be deemed illiquid if the underlying fund expects that a reasonable portion of the holding cannot be sold in seven calendar days or less without the sale significantly changing the market value of the investment. The determination of whether a holding is considered illiquid is made by the Series' adviser under a liquidity risk management program adopted by the Series' board and administered by the Series' adviser. The underlying fund may incur significant additional costs in disposing of illiquid securities.

**Loan assignments and participations —** The underlying fund may invest in loans or other forms of indebtedness that represent interests in amounts owed by corporations or other borrowers (collectively "borrowers"). Loans may be originated by the borrower in order to address its working capital needs, as a result of a reorganization of the borrower's assets and liabilities (recapitalizations), to merge with or acquire another company (mergers and acquisitions), to take control of another company (leveraged buy-outs), to provide temporary financing (bridge loans), or for other corporate purposes.

Some loans may be secured in whole or in part by assets or other collateral. The greater the value of the assets securing the loan the more the lender is protected against loss in the case of nonpayment of

principal or interest. Loans made to highly leveraged borrowers may be especially vulnerable to adverse changes in economic or market conditions and may involve a greater risk of default.

Some loans may represent revolving credit facilities or delayed funding loans, in which a lender agrees to make loans up to a maximum amount upon demand by the borrower during a specified term. These commitments may have the effect of requiring the underlying fund to increase its investment in a company at a time when it might not otherwise decide to do so (including at a time when the company's financial condition makes it unlikely that such amounts will be repaid).

Some loans may represent debtor-in-possession financings (commonly known as "DIP financings"). DIP financings are arranged when an entity seeks the protections of the bankruptcy court under Chapter 11 of the U.S. Bankruptcy Code. These financings allow the entity to continue its business operations while reorganizing under Chapter 11. Such financings constitute senior liens on unencumbered collateral (i.e., collateral not subject to other creditors' claims). There is a risk that the entity will not emerge from Chapter 11 and will be forced to liquidate its assets under Chapter 7 of the U.S. Bankruptcy Code. In the event of liquidation, the underlying fund's only recourse will be against the collateral securing the DIP financing.

The investment adviser generally makes investment decisions based on publicly available information, but may rely on non-public information if necessary. Borrowers may offer to provide lenders with material, non-public information regarding a specific loan or the borrower in general. The investment adviser generally chooses not to receive this information. As a result, the investment adviser may be at a disadvantage compared to other investors that may receive such information. The investment adviser's decision not to receive material, non-public information may impact the investment adviser's ability to assess a borrower's requests for amendments or waivers of provisions in the loan agreement. However, the investment adviser may on a case-by-case basis decide to receive such information when it deems prudent. In these situations the investment adviser may be restricted from trading the loan or buying or selling other debt and equity securities of the borrower while it is in possession of such material, non-public information, even if such loan or other security is declining in value.

The underlying fund normally acquires loan obligations through an assignment from another lender, but also may acquire loan obligations by purchasing participation interests from lenders or other holders of the interests. When the underlying fund purchases assignments, it acquires direct contractual rights against the borrower on the loan. The underlying fund acquires the right to receive principal and interest payments directly from the borrower and to enforce their rights as a lender directly against the borrower. However, because assignments are arranged through private negotiations between potential assignees and potential assignors, the rights and obligations acquired by the underlying fund as the purchaser of an assignment may differ from, and be more limited than, those held by the assigning lender. Loan assignments are often administered by a financial institution that acts as agent for the holders of the loan, and the underlying fund may be required to receive approval from the agent and/or borrower prior to the purchase of a loan. Risks may also arise due to the inability of the agent to meet its obligations under the loan agreement.

Loan participations are loans or other direct debt instruments that are interests in amounts owed by the borrower to another party. They may represent amounts owed to lenders or lending syndicates, to suppliers of goods or services, or to other parties. The underlying fund will have the right to receive payments of principal, interest and any fees to which it is entitled only from the lender selling the participation and only upon receipt by the lender of the payments from the borrower. In connection with purchasing participations, the underlying fund generally will have no right to enforce compliance by the borrower with the terms of the loan agreement relating to the loan, nor any rights of set-off against the borrower. In addition, the underlying fund may not directly benefit from any collateral supporting the loan in which it has purchased the participation and the underlying fund will have to rely on the agent bank or other financial intermediary to apply appropriate credit remedies. As a result, the underlying fund will be subject to the credit risk of both the borrower and the lender that is selling

------

the participation. In the event of the insolvency of the lender selling a participation, the underlying fund may be treated as a general creditor of the lender and may not benefit from any set-off between the lender and the borrower.

Investments in loan participations and assignments present the possibility that the underlying fund could be held liable as a co-lender under emerging legal theories of lender liability. In addition, if the loan is foreclosed, the underlying fund could be part owner of any collateral and could bear the costs and liabilities of owning and disposing of the collateral. The underlying fund anticipates that loan participations could be sold only to a limited number of institutional investors. In addition, some loan participations and assignments may not be rated by major rating agencies and may not be protected by securities laws.

**Unfunded commitment agreements —** The underlying fund may enter into unfunded commitment agreements to make certain investments, including unsettled bank loan purchase transactions. Under the SEC's rule applicable to the underlying fund's use of derivatives, unfunded commitment agreements are not derivatives transactions. The underlying fund will only enter into such unfunded commitment agreements if the underlying fund reasonably believes, at the time it enters into such agreement, that it will have sufficient cash and cash equivalents to meet its obligations with respect to all of its unfunded commitment agreements as they come due.

**Derivatives —** In pursuing its investment objective(s), the underlying fund may invest in derivative instruments. A derivative is a financial instrument, the value of which depends on, or is otherwise derived from, another underlying variable. Most often, the variable underlying a derivative is the price of a traded asset, such as a traditional cash security (e.g., a stock or bond), a currency or a commodity; however, the value of a derivative can be dependent on almost any variable, from the level of an index or a specified rate to the occurrence (or non-occurrence) of a credit event with respect to a specified reference asset. In addition to investing in forward currency contracts and currency options, as described under "Currency transactions," the underlying fund may take positions in futures contracts and options on futures contracts and swaps, each of which is a derivative instrument described in greater detail below.

Derivative instruments may be distinguished by the manner in which they trade: some are standardized instruments that trade on an organized exchange while others are individually negotiated and traded in the over-the-counter ("OTC") market. Derivatives also range broadly in complexity, from simple derivatives to more complex instruments. As a general matter, however, all derivatives — regardless of the manner in which they trade or their relative complexities — entail certain risks, some of which are different from, and potentially greater than, the risks associated with investing directly in traditional cash securities.

As is the case with traditional cash securities, derivative instruments are generally subject to counterparty credit risk; however, in some cases, derivatives may pose counterparty risks greater than those posed by cash securities. The use of derivatives involves the risk that a loss may be sustained by the underlying fund as a result of the failure of the underlying fund's counterparty to make required payments or otherwise to comply with its contractual obligations. For some derivatives, though, the value of — and, in effect, the return on — the instrument may be dependent on both the individual credit of the underlying fund's counterparty and on the credit of one or more issuers of any underlying assets. If the underlying fund does not correctly evaluate the creditworthiness of its counterparty and, where applicable, of issuers of any underlying reference assets, the underlying fund's investment in a derivative instrument may result in losses. Further, if the underlying fund's counterparty were to default on its obligations, the underlying fund's contractual remedies against such counterparty may be subject to applicable bankruptcy and insolvency laws, which could affect the underlying fund's rights as a creditor and delay or impede the underlying fund's ability to receive the net amount of payments that it is contractually entitled to receive. Derivative instruments are subject to additional risks, including operational risk (such as documentation issues, settlement issues and systems failures) and

American Funds Insurance Series – Managed Risk Funds — Page 31

------

legal risk (such as insufficient documentation, insufficient capacity or authority of a counterparty, and issues with the legality or enforceability of a contract).

The value of some derivative instruments in which the underlying fund invests may be particularly sensitive to changes in prevailing interest rates, currency exchange rates or other market conditions. Like the underlying fund's other investments, the ability of the underlying fund to successfully utilize such derivative instruments may depend in part upon the ability of the underlying fund's investment adviser to accurately forecast interest rates and other economic factors. The success of the underlying fund's derivative investment strategy will also depend on the investment adviser's ability to assess and predict the impact of market or economic developments on the derivative instruments in which the underlying fund invests, in some cases without having had the benefit of observing the performance of a derivative under all possible market conditions. If the investment adviser incorrectly forecasts such factors and has taken positions in derivative instruments contrary to prevailing market trends, or if the investment adviser incorrectly predicts the impact of developments on a derivative instrument, the underlying fund could suffer losses.

Certain derivatives may also be subject to liquidity and valuation risks. The potential lack of a liquid secondary market for a derivative (and, particularly, for an OTC derivative, including swaps and OTC options) may cause difficulty in valuing or selling the instrument. If a derivative transaction is particularly large or if the relevant market is illiquid, as is often the case with many privately-negotiated OTC derivatives, the underlying fund may not be able to initiate a transaction or to liquidate a position at an advantageous time or price. Particularly when there is no liquid secondary market for the underlying fund's derivative positions, the underlying fund may encounter difficulty in valuing such illiquid positions. The value of a derivative instrument does not always correlate perfectly with its underlying asset, rate or index, and many derivatives, and OTC derivatives in particular, are complex and often valued subjectively. Improper valuations can result in increased cash payment requirements to counterparties or a loss of value to the underlying fund.

Because certain derivative instruments may obligate the underlying fund to make one or more potential future payments, which could significantly exceed the value of the underlying fund's initial investments in such instruments, derivative instruments may also have a leveraging effect on the underlying fund's portfolio. Certain derivatives have the potential for unlimited loss, irrespective of the size of the underlying fund's investment in the instrument. When the underlying fund leverages its portfolio, investments in that underlying fund will tend to be more volatile, resulting in larger gains or losses in response to market changes.

The underlying fund's compliance with the SEC's rule applicable to the underlying fund's use of derivatives may limit the ability of the underlying fund to use derivatives as part of its investment strategy. The rule deems an underlying fund that uses derivatives only in a limited manner as a limited derivatives user and requires that such underlying fund adopt and implement written policies and procedures reasonably designed to manage the underlying fund's derivatives risks. The rule also deems an underlying fund that uses derivatives in more than a limited manner as a full derivatives user and requires that such an underlying fund adopt a derivatives risk management program, appoint a derivatives risk manager and comply with an outer limit on leverage based on value at risk, or "VaR". VaR is an estimate of an instrument's or portfolio's potential losses over a given time horizon (i.e., 20 trading days) and at a specified confidence level (i.e., 99%). VaR will not provide, and is not intended to provide, an estimate of an instrument's or portfolio's maximum potential loss amount. For example, a VaR of 5% with a specified confidence level of 99% would mean that a VaR model estimates that 99% of the time the underlying fund would not be expected to lose more than 5% of its total assets over the given time period. However, 1% of the time, the underlying fund would be expected to lose more than 5% of its total assets, and in such a scenario the VaR model does not provide an estimate of the extent of this potential loss. The derivatives rule may not be effective in limiting the underlying fund's risk of loss, as measurements of VaR rely on historical data and may not accurately measure the degree of risk reflected in the underlying fund's derivatives or other investments. The underlying fund is generally

American Funds Insurance Series – Managed Risk Funds — Page 32

------

required to satisfy the rule's outer limit on leverage by limiting the underlying fund's VaR to 200% of the VaR of a designated reference portfolio that does not utilize derivatives each business day. If the underlying fund does not have an appropriate designated reference portfolio in light of the underlying fund's investments, investment objectives and strategy, the underlying fund must satisfy the rule's outer limit on leverage by limiting the underlying fund's VaR to 20% of the value of the underlying fund's net assets each business day. The fund may invest in underlying funds that are either limited derivatives users or full derivatives users.

**Options** — The underlying fund may invest in option contracts, including options on futures and options on currencies, as described in more detail under "Futures and Options on Futures" and "Currency Transactions," respectively. An option contract is a contract that gives the holder of the option, in return for a premium payment, the right to buy from (in the case of a call) or sell to (in the case of a put) the writer of the option the reference instrument underlying the option (or the cash value of the instrument underlying the option) at a specified exercise price. The writer of an option on a security has the obligation, upon exercise of the option, to cash settle or deliver the underlying currency or instrument upon payment of the exercise price (in the case of a call) or to cash settle or take delivery of the underlying currency or instrument and pay the exercise price (in the case of a put).

By purchasing a put option, the underlying fund obtains the right (but not the obligation) to sell the currency or instrument underlying the option (or to deliver the cash value of the instrument underlying the option) at a specified exercise price, which is also referred to as the strike price. In return for this right, the underlying fund pays the current market price, or the option premium, for the option. The underlying fund may terminate its position in a put option by allowing the option to expire or by exercising the option. If the option is allowed to expire, the underlying fund will lose the entire amount of the option premium paid. If the option is exercised, the underlying fund completes the sale of the underlying instrument (or cash settles) at the strike price. The underlying fund may also terminate a put option position by entering into opposing close-out transactions in advance of the option expiration date.

As a buyer of a put option, the underlying fund can expect to realize a gain if the price of the underlying currency or instrument falls substantially. However, if the price of the underlying currency or instrument does not fall enough to offset the cost of purchasing the option, the underlying fund can expect to suffer a loss, albeit a loss limited to the amount of the option premium plus any applicable transaction costs.

The features of call options are essentially the same as those of put options, except that the purchaser of a call option obtains the right (but not the obligation) to purchase, rather than sell, the underlying currency or instrument (or cash settle) at the specified strike price. The buyer of a call option typically attempts to participate in potential price increases of the underlying currency or instrument with risk limited to the cost of the option if the price of the underlying currency or instrument falls. At the same time, the call option buyer can expect to suffer a loss if the price of the underlying currency or instrument does not rise sufficiently to offset the cost of the option.

The writer of a put or call option takes the opposite side of the transaction from the option purchaser. In return for receipt of the option premium, the writer assumes the obligation to pay or receive the strike price for the option's underlying currency or instrument if the other party to the option chooses to exercise it. The writer may seek to terminate a position in a put option before exercise by entering into opposing close-out transactions in advance of the option expiration date. If the market for the relevant put option is not liquid, however, the writer must be prepared to pay the strike price while the option is outstanding, regardless of price changes.

American Funds Insurance Series – Managed Risk Funds — Page 33

------

If the price of the underlying currency or instrument rises, a put writer would generally expect to profit, although its gain would be limited to the amount of the premium it received. If the price of the underlying currency or instrument remains the same over time, it is likely that the writer would also profit because it should be able to close out the option at a lower price. This is because an option's value decreases with time as the currency or instrument approaches its expiration date. If the price of the underlying currency or instrument falls, the put writer would expect to suffer a loss. This loss should be less than the loss from purchasing the underlying currency or instrument directly, however, because the premium received for writing the option should mitigate the effects of the decline.

Writing a call option obligates the writer to, upon exercise of the option, deliver the option's underlying currency or instrument in return for the strike price or to make a net cash settlement payment, as applicable. The characteristics of writing call options are similar to those of writing put options, except that writing call options is generally a profitable strategy if prices remain the same or fall. The potential gain for the option seller in such a transaction would be capped at the premium received.

Several risks are associated with transactions in options on currencies, securities and other instruments (referred to as the "underlying instruments"). For example, there may be significant differences between the underlying instruments and options markets that could result in an imperfect correlation between these markets, which could cause a given transaction not to achieve its objectives. When a put or call option on a particular underlying instrument is purchased to hedge against price movements in a related underlying instrument, for example, the price to close out the put or call option may move more or less than the price of the related underlying instrument.

Options prices can diverge from the prices of their underlying instruments for a number of reasons. Options prices are affected by such factors as current and anticipated short-term interest rates, changes in the volatility of the underlying instrument, and the time remaining until expiration of the contract, which may not affect security prices in the same way. Imperfect correlation may also result from differing levels of demand in the options markets and the markets for the underlying instruments, from structural differences in how options and underlying instruments are traded, or from imposition of daily price fluctuation limits or trading halts. The underlying fund may purchase or sell options contracts with a greater or lesser value than the underlying instruments it wishes to hedge or intends to purchase in order to attempt to compensate for differences in volatility between the contract and the underlying instruments, although this may not be successful. If price changes in the underlying fund's options positions are less correlated with its other investments, the positions may fail to produce anticipated gains or result in losses that are not offset by gains in other investments.

There is no assurance that a liquid market will exist for any particular options contract at any particular time. Options may have relatively low trading volumes and liquidity if their strike prices are not close to the current prices of the underlying instruments. In addition, exchanges may establish daily price fluctuation limits for exchange-traded options contracts and may halt trading if a contract's price moves upward or downward more than the limit in a given day. On volatile trading days when the price fluctuation limit is reached or a trading halt is imposed, it may be impossible to enter into new positions or to close out existing positions. If the market for a contract is not liquid because of price fluctuation limits or otherwise, it could prevent prompt liquidation of unfavorable positions and could potentially require the underlying fund to hold a position until delivery or expiration regardless of changes in its value.

Combined positions involve purchasing and writing options in combination with each other, or in combination with futures or forward contracts, in order to adjust the risk and return profile of the underlying fund's overall position. For example, purchasing a put option and writing a call

American Funds Insurance Series – Managed Risk Funds — Page 34

------

option on the same underlying instrument could construct a combined position with risk and return characteristics similar to selling a futures contract (but with leverage embedded). Another possible combined position would involve writing a call option at one strike price and buying a call option at a lower strike price to reduce the risk of the written call option in the event of a substantial price increase. Because such combined options positions involve multiple trades, they result in higher transaction costs and may be more difficult to open and close out.

**Futures and options on futures** — The underlying fund may enter into futures contracts and options on futures contracts to seek to manage the underlying fund's interest rate sensitivity by increasing or decreasing the duration of the underlying fund or a portion of the underlying fund's portfolio. A futures contract is an agreement to buy or sell a security or other financial instrument (the "reference asset") for a set price on a future date. An option on a futures contract gives the holder of the option the right to buy or sell a position in a futures contract from or to the writer of the option, at a specified price on or before the specified expiration date. Futures contracts and options on futures contracts are standardized, exchange-traded contracts, and, when such contracts are bought or sold, the underlying fund will incur brokerage fees and will be required to maintain margin deposits.

Unlike when the underlying fund purchases or sells a security, such as a stock or bond, no price is paid or received by the underlying fund upon the purchase or sale of a futures contract. When the underlying fund enters into a futures contract, the underlying fund is required to deposit with its futures broker, known as a futures commission merchant ("FCM"), a specified amount of liquid assets in a segregated account in the name of the FCM at the applicable derivatives clearinghouse or exchange. This amount, known as initial margin, is set by the futures exchange on which the contract is traded and may be significantly modified during the term of the contract. The initial margin is in the nature of a performance bond or good faith deposit on the futures contract, which is returned to the underlying fund upon termination of the contract, assuming all contractual obligations have been satisfied. Additionally, on a daily basis, the underlying fund pays or receives cash, or variation margin, equal to the daily change in value of the futures contract. Variation margin does not represent a borrowing or loan by the underlying fund but is instead a settlement between the underlying fund and the FCM of the amount one party would owe the other if the futures contract expired. In computing daily net asset value, the underlying fund will mark-to-market its open futures positions. An underlying fund is also required to deposit and maintain margin with an FCM with respect to put and call options on futures contracts written by the underlying fund. Such margin deposits will vary depending on the nature of the underlying futures contract (and related initial margin requirements), the current market value of the option, and other futures positions held by the underlying fund. In the event of the bankruptcy or insolvency of an FCM that holds margin on behalf of the underlying fund, the underlying fund may be entitled to return of margin owed to it only in proportion to the amount received by the FCM's other customers, potentially resulting in losses to the underlying fund. An event of bankruptcy or insolvency at a clearinghouse or exchange holding initial margin could also result in losses for the underlying fund.

When the underlying fund invests in futures contracts and options on futures contracts and deposits margin with an FCM, the underlying fund becomes subject to so-called "fellow customer" risk – that is, the risk that one or more customers of the FCM will default on their obligations and that the resulting losses will be so great that the FCM will default on its obligations and margin posted by one customer, such as the underlying fund, will be used to cover a loss caused by a different defaulting customer. Applicable Commodity Futures Trading Commission ("CFTC") rules generally prohibit the use of one customer's funds to meet the obligations of another customer and limit the ability of an FCM to use margin posed by non-defaulting customers to satisfy losses caused by defaulting customers. As a general matter, an

American Funds Insurance Series – Managed Risk Funds — Page 35

------

FCM is required to use its own funds to meet a defaulting customer's obligations. While a customer's loss would likely need to be substantial before non-defaulting customers would be exposed to loss on account of fellow customer risk, applicable CFTC rules nevertheless permit the commingling of margin and do not limit the mutualization of customer losses from investment losses, custodial failures, fraud or other causes. If the loss is so great that, notwithstanding the application of an FCM's own funds, there is a shortfall in the amount of customer funds required to be held in segregation, the FCM could default and be placed into bankruptcy. Under these circumstances, bankruptcy law provides that non-defaulting customers will share pro rata in any shortfall. A shortfall in customer segregated funds may also make the transfer of the accounts of non-defaulting customers to another FCM more difficult.

Although certain futures contracts, by their terms, require actual future delivery of and payment for the reference asset, in practice, most futures contracts are usually closed out before the delivery date by offsetting purchases or sales of matching futures contracts. Closing out an open futures contract purchase or sale is effected by entering into an offsetting futures contract sale or purchase, respectively, for the same aggregate amount of the identical reference asset and the same delivery date. If the offsetting purchase price is less than the original sale price (in each case taking into account transaction costs, including brokerage fees), the underlying fund realizes a gain; if it is more, the underlying fund realizes a loss. Conversely, if the offsetting sale price is more than the original purchase price (in each case taking into account transaction costs, including brokerage fees), the underlying fund realizes a gain; if it is less, the underlying fund realizes a loss.

The underlying fund may purchase and write call and put options on futures. A futures option gives the holder the right, in return for the premium paid, to assume a long position (call) or short position (put) in a futures contract at a specified exercise price at any time during the period of the option. Upon exercise of a call option, the holder acquires a long position in the futures contract, and the writer is assigned the opposite short position. The opposite is true in the case of a put option. A call option is "in the money" if the value of the futures contract that is the subject of the option exceeds the exercise price. A put option is "in the money" if the exercise price exceeds the value of the futures contract that is the subject of the option. See also "Options" above for a general description of investment techniques and risks relating to options.

The value of a futures contract tends to increase and decrease in tandem with the value of its underlying reference asset. Purchasing futures contracts will, therefore, tend to increase the underlying fund's exposure to positive and negative price fluctuations in the reference asset, much as if the underlying fund had purchased the reference asset directly. When the underlying fund sells a futures contract, by contrast, the value of its futures position will tend to move in a direction contrary to the market for the reference asset. Accordingly, selling futures contracts will tend to offset both positive and negative market price changes, much as if the reference asset had been sold.

There is no assurance that a liquid market will exist for any particular futures or futures options contract at any particular time. Futures exchanges may establish daily price fluctuation limits for futures contracts and may halt trading if a contract's price moves upward or downward more than the limit in a given day. On volatile trading days, when the price fluctuation limit is reached and a trading halt is imposed, it may be impossible to enter into new positions or close out existing positions. If the market for a futures contract is not liquid because of price fluctuation limits or other market conditions, the underlying fund may be prevented from promptly liquidating unfavorable futures positions and the underlying fund could be required to continue to hold a position until delivery or expiration regardless of changes in its value, potentially subjecting the underlying fund to substantial losses. Additionally, the underlying fund may not be able to take other actions or enter into other transactions to limit or reduce its

American Funds Insurance Series – Managed Risk Funds — Page 36

------

exposure to the position. Under such circumstances, the underlying fund would remain obligated to meet margin requirements until the position is cleared. As a result, the underlying fund's access to other assets posted as margin for its futures positions could also be impaired.

Although futures exchanges generally operate similarly in the United States and abroad, foreign futures exchanges may follow trading, settlement and margin procedures that are different than those followed by futures exchanges in the United States. Futures and futures options contracts traded outside the United States may not involve a clearing mechanism or related guarantees and may involve greater risk of loss than U.S.-traded contracts, including potentially greater risk of losses due to insolvency of a futures broker, exchange member, or other party that may owe initial or variation margin to the underlying fund. Margin requirements on foreign futures exchanges may be different than those of futures exchanges in the United States, and, because initial and variation margin payments may be measured in foreign currency, a futures or futures options contract traded outside the United States may also involve the risk of foreign currency fluctuations.

**Swaps —** The underlying fund may enter into swaps, which are two-party contracts entered into primarily by institutional investors for a specified time period. In a typical swap, two parties agree to exchange the returns earned or realized from one or more underlying assets or rates of return.

Swaps can be traded on a swap execution facility ("SEF") and cleared through a central clearinghouse (cleared), traded OTC and cleared, or traded bilaterally and not cleared. For example, standardized interest rate swaps and standardized credit default swap indices are traded on SEFs and cleared. Other forms of swaps, such as total return swaps and certain types of interest rate swaps and credit default swap indices are entered into on a bilateral basis. Because clearing interposes a central clearinghouse as the ultimate counterparty to each participant's swap, and margin is required to be exchanged under the rules of the clearinghouse, central clearing is intended to decrease (but not eliminate) counterparty risk relative to uncleared bilateral swaps. To the extent the underlying fund enters into bilaterally negotiated swaps, the underlying fund will enter into swaps only with counterparties that meet certain credit standards and have agreed to specific collateralization procedures; however, if the counterparty's creditworthiness deteriorates rapidly and the counterparty defaults on its obligations under the swap or declares bankruptcy, the underlying fund may lose any amount it expected to receive from the counterparty. In addition, bilateral swaps are subject to certain regulatory margin requirements that mandate the posting and collection of minimum margin amounts, which may result in the underlying fund and its counterparties posting higher margin amounts for bilateral swaps than would otherwise be the case.

The term of a swap can be days, months or years and certain swaps may be less liquid than others. If a swap is particularly large or if the relevant market is illiquid, it may not be possible to initiate a transaction or liquidate a position at an advantageous time or price, which may result in significant losses.

Swaps can take different forms. The underlying fund may enter into the following types of swaps:

**Interest rate swaps —** The underlying fund may enter into interest rate swaps to seek to manage the interest rate sensitivity of the underlying fund by increasing or decreasing the duration of the underlying fund or a portion of the underlying fund's portfolio. An interest rate swap is an agreement between two parties to exchange or swap payments based on changes in an interest rate or rates. Typically, one interest rate is fixed and the other is variable based on a designated short-term interest rate such as the

American Funds Insurance Series – Managed Risk Funds — Page 37

Secured Overnight Financing Rate ("SOFR"), prime rate or other benchmark, or on an inflation index such as the U.S. Consumer Price Index (which is a measure that examines the weighted average of prices of a basket of consumer goods and services and measures changes in the purchasing power of the U.S. dollar and the rate of inflation). In other types of interest rate swaps, known as basis swaps, the parties agree to swap variable interest rates based on different designated short-term interest rates. Interest rate swaps generally do not involve the delivery of securities or other principal amounts. Rather, cash payments are exchanged by the parties based on the application of the designated interest rates to a notional amount, which is the predetermined dollar principal of the trade upon which payment obligations are computed. Accordingly, the underlying fund's current obligation or right under the swap is generally equal to the net amount to be paid or received under the swap based on the relative value of the position held by each party.

In addition to the risks of entering into swaps discussed above, the use of interest rate swaps involves the risk of losses if interest rates change.

**Total return swaps —** The underlying fund may enter into total return swaps in order to gain exposure to a market or security without owning or taking physical custody of such security or investing directly in such market. A total return swap is an agreement in which one party agrees to make periodic payments to the other party based on the change in market value of the assets underlying the contract during the specified term in exchange for periodic payments based on a fixed or variable interest rate or the total return from other underlying assets. The asset underlying the contract may be a single security, a basket of securities or a securities index. Like other swaps, the use of total return swaps involves certain risks, including potential losses if a counterparty defaults on its payment obligations to the underlying fund or the underlying assets do not perform as anticipated. There is no guarantee that entering into a total return swap will deliver returns in excess of the interest costs involved and, accordingly, the underlying fund's performance may be lower than would have been achieved by investing directly in the underlying assets.

**Credit default swap indices —** In order to assume exposure to a diversified portfolio of credits or to hedge against existing credit risks, the underlying fund may invest in credit default swap indices, including CDX and iTraxx indices (collectively referred to as "CDSIs"). Additionally, in order to assume exposure to the commercial mortgage-backed security sector or to hedge against existing credit and market risks within such sector, the fund may invest in mortgage-backed security credit default swap indices, including the CMBX index (collectively referred to as "CMBXIs").

A CDSI is based on a portfolio of credit default swaps with similar characteristics, such as credit default swaps on high-yield bonds. A CMBXI is a tradeable index referencing a basket of commercial mortgage-backed securities. In a typical CDSI or CMBXI transaction, one party — the protection buyer — is obligated to pay the other party — the protection seller — a stream of periodic payments over the term of the contract. If a credit event, such as a default or restructuring, occurs with respect to any of the underlying reference obligations, the protection seller must pay the protection buyer the loss on those credits. Also, if a restructuring credit event occurs in an iTraxx index, the underlying fund as protection buyer may receive a single name credit default swap ("CDS") representing the relevant constituent.

The underlying fund may enter into a CDSI or CMBXI transaction as either protection buyer or protection seller. If the underlying fund is a protection buyer, it would pay the counterparty a periodic stream of payments over the term of the contract and would

not recover any of those payments if no credit events were to occur with respect to any of the underlying reference obligations. However, if a credit event did occur, the underlying fund, as a protection buyer, would have the right to deliver the referenced debt obligations or a specified amount of cash, depending on the terms of the applicable agreement, and to receive the par value of such debt obligations from the counterparty protection seller. As a protection seller, the underlying fund would receive fixed payments throughout the term of the contract if no credit events were to occur with respect to any of the underlying reference obligations. If a credit event were to occur, however, the value of any deliverable obligation received by the underlying fund, coupled with the periodic payments previously received by the underlying fund, may be less than the full notional value that the underlying fund, as a protection seller, pays to the counterparty protection buyer, effectively resulting in a loss of value to the underlying fund. Furthermore, as a protection seller, the underlying fund would effectively add leverage to its portfolio because it would have investment exposure to the notional amount of the swap.

The use of CDSI or CMBXI, like all other swaps, is subject to certain risks, including the risk that the underlying fund's counterparty will default on its obligations. If such a default were to occur, any contractual remedies that the underlying fund might have may be subject to applicable bankruptcy laws, which could delay or limit the underlying fund's recovery. Thus, if the underlying fund's counterparty to a CDSI or CMBXI transaction defaults on its obligation to make payments thereunder, the underlying fund may lose such payments altogether or collect only a portion thereof, which collection could involve substantial costs or delays.

Additionally, when the underlying fund invests in a CDSI or CMBXI as a protection seller, the underlying fund will be indirectly exposed to the creditworthiness of issuers of the underlying reference obligations in the index. If the investment adviser to the underlying fund does not correctly evaluate the creditworthiness of issuers of the underlying instruments on which the CDSI or CMBXI is based, the investment could result in losses to the underlying fund.

**Repurchase agreements —** The underlying fund may enter into repurchase agreements, or "repos", under which the underlying fund buys a security and obtains a simultaneous commitment from the seller to repurchase the security at a specified time and price. Because the security purchased constitutes collateral for the repurchase obligation, a repo may be considered a loan by the underlying fund that is collateralized by the security purchased. Repos permit the underlying fund to maintain liquidity and earn income over periods of time as short as overnight.

The seller must maintain with a custodian collateral equal to at least the repurchase price, including accrued interest. In tri-party repos and centrally cleared or "sponsored" repos, a third-party custodian, either a clearing bank in the case of tri-party repos or a central clearing counterparty in the case of centrally cleared repos, facilitates repo clearing and settlement, including by providing collateral management services. In bilateral repos, the parties themselves are responsible for settling transactions.

The underlying fund will only enter into repos involving securities of the type in which they could otherwise invest. If the seller under the repo defaults, the underlying fund may incur a loss if the value of the collateral securing the repo has declined and may incur disposition costs and delays in connection with liquidating the collateral. If bankruptcy proceedings are commenced with respect to the seller, realization of the collateral by the underlying fund may be delayed or limited.

------

**Cash and cash equivalents —** The underlying fund may also hold cash or invest in cash equivalents. Cash equivalents include, but are not limited to: (*a*) shares of money market or similar funds managed by the investment adviser or its affiliates; (*b*) shares of other money market funds; (*c*) commercial paper; (*d*) short-term bank obligations (for example, certificates of deposit, bankers' acceptances (time drafts on a commercial bank where the bank accepts an irrevocable obligation to pay at maturity)) or bank notes; (*e*) savings association and savings bank obligations (for example, bank notes and certificates of deposit issued by savings banks or savings associations); (*f*) securities of the U.S. government, its agencies or instrumentalities that mature, or that may be redeemed, in one year or less; and (*g*) higher quality corporate bonds and notes that mature, or that may be redeemed, in one year or less.

There is no limit on the extent to which the underlying fund may take temporary defensive measures. In taking such measures, the underlying fund may fail to achieve its investment objective.

**Commercial paper —** An underlying fund may purchase commercial paper. Commercial paper refers to short-term promissory notes issued by a corporation to finance its current operations. Such securities normally have maturities of thirteen months or less and, though commercial paper is often unsecured, commercial paper may be supported by letters of credit, surety bonds or other forms of collateral. Maturing commercial paper issuances are usually repaid by the issuer from the proceeds of new commercial paper issuances. As a result, investment in commercial paper is subject to rollover risk, or the risk that the issuer cannot issue enough new commercial paper to satisfy its outstanding commercial paper. Like all fixed income securities, commercial paper prices are susceptible to fluctuations in interest rates. If interest rates rise, commercial paper prices will decline and vice versa. However, the short-term nature of a commercial paper investment makes it less susceptible to volatility than many other fixed income securities because interest rate risk typically increases as maturity lengths increase. Commercial paper tends to yield smaller returns than longer-term corporate debt because securities with shorter maturities typically have lower effective yields than those with longer maturities. As with all fixed income securities, there is a chance that the issuer will default on its commercial paper obligations and commercial paper may become illiquid or suffer from reduced liquidity in these or other situations.

Commercial paper in which an underlying fund may invest includes commercial paper issued in reliance on the exemption from registration afforded by Section 4(a)(2) of the Securities Act of 1933, as amended (the "1933 Act"). Section 4(a)(2) commercial paper has substantially the same price and liquidity characteristics as commercial paper generally, except that the resale of Section 4(a)(2) commercial paper is limited to institutional investors who agree that they are purchasing the paper for investment purposes and not with a view to public distribution. Technically, such a restriction on resale renders Section 4(a)(2) commercial paper a restricted security under the 1933 Act. In practice, however, Section 4(a)(2) commercial paper typically can be resold as easily as any other unrestricted security held by the fund. Accordingly, Section 4(a)(2) commercial paper has been generally determined to be liquid under procedures adopted by the underlying fund's board of trustees.

**Investments in registered open-end investment companies and unit investment trusts —** The underlying fund may not acquire securities of open-end investment companies or investment unit trusts registered under the Investment Company Act of 1940 in reliance on Section 12(d)(1)(F) or 12(d)(1)(G) of the Investment Company Act.

**Affiliated investment companies —** An underlying fund may purchase shares of certain other investment companies managed by the investment adviser or its affiliates ("Central Funds"). The risks of owning another investment company are similar to the risks of investing directly in the securities in which that investment company invests. Investments in other investment companies could allow the underlying fund to obtain the benefits of a more diversified portfolio than might otherwise be available through direct investments in a particular asset class, and will subject the underlying fund to the risks associated with the particular asset class or asset classes in which an underlying fund invests. However,

American Funds Insurance Series – Managed Risk Funds — Page 40

------

an investment company may not achieve its investment objective or execute its investment strategy effectively, which may adversely affect the underlying fund's performance. Any investment in another investment company will be consistent with the underlying fund's objective(s) and applicable regulatory limitations. Central Funds do not charge management fees. As a result, the underlying fund does not bear additional management fees when investing in Central Funds, but the underlying fund does bear its proportionate share of Central Fund expenses.

**Inflation/Deflation risk —** The underlying fund may be subject to inflation and deflation risk. Inflation risk is the risk that the present value of assets or income from investments will be less in the future as inflation decreases the value of money. As inflation increases, the present value of the underlying funds' assets can decline. Deflation risk is the risk that prices throughout the economy decline over time. Deflation or inflation may have an adverse effect on the creditworthiness of issuers and may make issuer default more likely, which may result in a decline in the value of the underlying funds' assets.

**Washington Mutual Investors Fund and its investment policies —** Washington Mutual Investors Fund has an Eligible List of securities considered appropriate for a prudent investor seeking opportunities for income and growth of principal consistent with common stock investing. Numerous criteria govern which securities may be included on the fund's Eligible List. Currently, those criteria include, for example: (a) a security shall be listed on the New York Stock Exchange ("NYSE") or meet the financial listing requirements of the NYSE (the applicable listing requirements are set forth in Section 1 of the Listed Company Manual of the NYSE); (b) most companies must have fully earned their dividends in at least four of the past five years (with the exception of certain banking institutions) and paid a dividend in at least eight of the past ten years; (c) issuing companies must meet both initial and ongoing market capitalization requirements; and (d) the ratio of current assets to liabilities for most individual companies must be at least 1.5 to 1, or their bonds must be rated at least investment grade by S&P Global Ratings. The investment adviser generates and maintains the Eligible List and selects the fund's investments exclusively from the securities on the Eligible List.

Although the fund generally invests in U.S. companies, the fund may invest up to 10% of its assets in securities of certain companies domiciled outside the United States. The fund may also hold securities of companies domiciled outside the United States when such companies have merged with or otherwise acquired a company in which the fund held shares at the time of the merger.

It is believed that in applying the above disciplines and procedures, the fund makes available to pension and profit-sharing trustees and other fiduciaries a prudent stock investment and a continuity of investment quality which it has always been the policy of the fund to provide. However, fiduciary investment responsibility and the Prudent Investor Rule, pursuant to which a fiduciary is generally required to invest and manage trust assets as a prudent investor would, involve a mixed question of law and fact which cannot be conclusively determined in advance. Moreover, recent changes to the Prudent Investor Rule in some jurisdictions speak to an allocation of funds among a variety of investments. Therefore, each fiduciary should examine the common stock portfolio of the fund to see that it, along with other investments, meets the requirements of the specific trust.

**Portfolio turnover —** Higher portfolio turnover may involve correspondingly greater transaction costs in the form of dealer spreads or brokerage commissions. It may also result in the realization of net capital gains, which are taxable when distributed to shareholders, unless the shareholder is exempt from taxation or his or her account is tax-favored.

A fund's portfolio turnover rate would equal 100% if each security in the fund's portfolio were replaced once per year. The following table sets forth the portfolio turnover rates for each fund for the fiscal years ended December 31, 2025 and 2024. Variations in turnover rate are due to changes in trading activity during the period.

**Fund policies**

All percentage limitations in the following fund policies are considered at the time securities are purchased and are based on the fund's net assets unless otherwise indicated. None of the following policies involving a maximum percentage of assets will be considered violated unless the excess occurs immediately after, and is caused by, an acquisition by the fund. In managing the fund, the fund's investment adviser may apply more restrictive policies than those listed below.

**Fundamental policies —** The Series has adopted the following policies, which may not be changed without approval by holders of a majority of its outstanding shares. Such majority is currently defined in the Investment Company Act of 1940, as amended (the "1940 Act"), as the vote of the lesser of (*a*) 67% or more of the voting securities present at a shareholder meeting, if the holders of more than 50% of the outstanding voting securities are present in person or by proxy, or (*b*) more than 50% of the outstanding voting securities.

Except where the context indicates otherwise, the following policies apply to each fund in the Series (please also see "Additional information about fundamental policies" below):

1. Except as permitted by (*i*) the 1940 Act and the rules and regulations thereunder, or other successor law governing the regulation of registered investment companies, or interpretations or modifications thereof by the U.S. Securities and Exchange Commission ("SEC"), SEC staff or other authority of competent jurisdiction, or (*ii*) exemptive or other relief or permission from the SEC, SEC staff or other authority of competent jurisdiction, the fund may not:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;d.Purchase or sell real estate or commodities;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;e.Make loans; or

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;f.Purchase the securities of any issuer if, as a result of such purchase, the fund's investments would be concentrated in any particular industry.

2. The fund may not invest in companies for the purpose of exercising control or management.

3. For Managed Risk Washington Mutual Investors Fund, the fund may not invest more than 5% of net assets in money market instruments, after allowing for sales of portfolio securities and fund shares within 30 days and the accumulation of cash balances representing undistributed net investment income and realized capital gains, in order to maintain a fully invested portfolio.

**Additional information about fundamental policies** — The information below is not part of the Series' fundamental policies. This information is intended to provide a summary of what is currently required or permitted by the 1940 Act and the rules and regulations thereunder, or by the interpretive guidance thereof by the SEC or SEC staff, for particular fundamental policies of the Series. Information is also provided regarding the fund's current intention with respect to certain investment practices permitted by the 1940 Act.

For purposes of fundamental policy 1a, the fund may borrow money in amounts of up to 33-1/3% of its total assets from banks for any purpose. Additionally, the fund may borrow up to 5% of its total assets from banks or other lenders for temporary purposes (a loan is presumed to be for temporary purposes if it is repaid within 60 days and is not extended or renewed). The percentage limitations in this policy are considered at the time of borrowing and thereafter.

For purposes of fundamental policy 1b, a senior security does not include any promissory note or evidence of indebtedness if such loan is for temporary purposes only and in an amount not exceeding 5% of the value of the total assets of the fund at the time the loan is made (a loan is presumed to be for temporary purposes if it is repaid within 60 days and is not extended or renewed). Further, the fund is permitted to enter into derivatives and certain other transactions, notwithstanding the prohibitions and restrictions on the issuance of senior securities under the 1940 Act, in accordance with current SEC rules and interpretations.

For purposes of fundamental policy 1c, the policy will not apply to the fund to the extent the fund may be deemed an underwriter within the meaning of the 1933 Act in connection with the purchase and sale of fund portfolio securities in the ordinary course of pursuing its investment objective(s) and strategies.

For purposes of fundamental policy 1e, the fund may not lend more than 33-1/3% of its total assets, provided that this limitation shall not apply to the fund's purchase of debt obligations, money market instruments and repurchase agreements.

For purposes of fundamental policy 1f, the fund may not invest more than 25% of its total assets in the securities of issuers in a particular industry. For purposes of calculating compliance with restrictions on industry concentrations, the fund will look through to the securities held by the underlying fund in which it invests. This policy does not apply to investments in securities of the United States government, its agencies or instrumentalities or government sponsored entities or repurchase agreements with respect thereto. The fund does not consider the futures or options contracts in which it currently invests – namely, futures and options on broad-based equity indices – to be an industry for these purposes. The fund may, however, invest substantially all of its assets in one or more investment companies managed by Capital Research and Management Company.

For purposes of fundamental policy 3, money market instruments include one or more money market or similar funds managed by the investment adviser or its affiliates.

**Management of the Series**

**Board of trustees and officers**

**Independent trustees<sup>1</sup>**

The Series' nominating and governance committee and board select independent trustees with a view toward constituting a board that, as a body, possesses the qualifications, skills, attributes and experience to appropriately oversee the actions of the Series' service providers, decide upon matters of general policy and represent the long-term interests of fund shareholders. In doing so, they consider the qualifications, skills, attributes and experience of the current board members, with a view toward maintaining a board that is diverse in viewpoint, experience, education and skills.

The Series seeks independent trustees who have high ethical standards and the highest levels of integrity and commitment, who have inquiring and independent minds, mature judgment, good communication skills, and other complementary personal qualifications and skills that enable them to function effectively in the context of the Series' board and committee structure and who have the ability and willingness to dedicate sufficient time to effectively fulfill their duties and responsibilities.

Each independent trustee has a significant record of accomplishments in governance, business, not-for-profit organizations, government service, academia, law, accounting or other professions. Although no single list could identify all experience upon which the Series' independent trustees draw in connection with their service, the following table summarizes key experience for each independent trustee. These references to the qualifications, attributes and skills of the trustees are pursuant to the disclosure requirements of the SEC, and shall not be deemed to impose any greater responsibility or liability on any trustee or the board as a whole. Notwithstanding the accomplishments listed below, none of the independent trustees is considered an "expert" within the meaning of the federal securities laws with respect to information in the Series' registration statement.

<sup>1</sup> Ownership disclosure is made using the following ranges: None; $1 – $10,000; $10,001 – $50,000; $50,001 – $100,000; and Over $100,000. The amounts listed for interested trustees include shares owned through The Capital Group Companies, Inc. retirement plan and/or 401(k) plan, as applicable.

<sup>2</sup> N/A indicates that the listed individual, as of December 31, 2025, was not a trustee of the fund (or, as applicable, other funds in the same family of investment companies as the fund), did not allocate deferred compensation to the fund, or did not participate in the deferred compensation plan.

<sup>3</sup>Shares of the funds may only be owned by purchasing variable annuity and variable life insurance contracts. Each trustee's need for variable annuity or variable life contracts and the role those contracts would play in his or her comprehensive investment portfolio will vary and depend on a number of factors including tax, estate planning, life insurance, alternative retirement plans or other considerations.

<sup>4</sup>Eligible trustees may defer their compensation under a nonqualified deferred compensation plan. Amounts deferred by the trustee accumulate at an earnings rate determined by the total return of one or more American Funds as designated by the trustee.

<sup>5</sup>The funds in the Series are not available for investment in the independent trustees' deferred compensation plan.

**Trustee compensation —** No compensation is paid by the Series to any officer or trustee who is a director, officer or employee of the investment adviser or its affiliates. Except for the independent trustees listed in the "Board of trustees and officers — Independent trustees" table under the "Management of the Series" section in this statement of additional information, all other officers and trustees of the Series are directors, officers or employees of the investment adviser or its affiliates. The board typically meets either individually or jointly with the boards of one or more other such funds with substantially overlapping board membership (in each case referred to as a "board cluster"). The Series typically pays each independent trustee an annual retainer fee based primarily on the total number of board clusters which that independent trustee serves. Board and committee chairs receive additional fees for their services.

The Series and the other funds served by each independent trustee each pay a portion of these fees.

No pension or retirement benefits are accrued as part of Series expenses. Generally, independent trustees may elect, on a voluntary basis, to defer all or a portion of their fees through a deferred compensation plan in effect for the Series. The Series also reimburses certain expenses of the independent trustees.

<sup>1</sup> Amounts may be deferred by eligible trustees under a nonqualified deferred compensation plan adopted by the Series in 1993. Deferred amounts accumulate at an earnings rate determined by the total return of one or more American Funds as designated by the trustees. Compensation shown in this table for the fiscal year ended December 31, 2025 does not include earnings on amounts deferred in previous fiscal years. See footnote 2 to this table for more information.

<sup>2</sup> Since the deferred compensation plan's adoption, the total amount of deferred compensation accrued by the Series (plus earnings thereon) through the end of the 2025 fiscal year for participating trustees is as follows: Francisco G. Cigarroa ($168,656), Nariman Farvardin ($676,191), Jennifer C. Feikin ($206,613), Merit E. Janow ($53,761), Margaret Spellings ($558,496), Alexandra Trower ($580,410) and Paul S. Williams ($115,942). Amounts deferred and accumulated earnings thereon are not funded and are general unsecured liabilities of the Series until paid to the trustees.

**Series organization and the board of trustees —** The Series, an open-end investment company, was organized as a Massachusetts business trust on September 13, 1983. At a meeting of the Series' shareholders on November 24, 2009, shareholders approved the reorganization of the Series to a Delaware statutory trust. However, the Series reserved the right to delay implementing the reorganization and has elected to do so. A summary comparison of the governing documents and state laws affecting the Delaware statutory trust and the current form of organization of the Series can be found in the proxy statement for the Series dated August 28, 2009, which is available on the SEC's website at sec.gov.

All Series operations are supervised by its board of trustees, which meets periodically and performs duties required by applicable state and federal laws. Independent board members are paid certain fees for services rendered to the Series as described above. They may elect to defer all or a portion of these fees through a deferred compensation plan in effect for the Series.

Massachusetts common law provides that a trustee of a Massachusetts business trust owes a fiduciary duty to the trust and must carry out his or her responsibilities as a trustee in accordance with that fiduciary duty. Generally, a trustee will satisfy his or her duties if he or she acts in good faith and uses ordinary prudence.

The Series currently consists of separate funds which have separate assets and liabilities, and invest in separate investment portfolios. The board of trustees may create additional funds in the future. Income, direct liabilities and direct operating expenses of a fund will be allocated directly to that fund and general liabilities and expenses of the Series will be allocated among the funds in proportion to the total net assets of each fund.

The funds have Class P1 and Class P2 shares. Other funds in the Series have Class 1, Class 1A, Class 2, Class 3 and/or Class 4 shares. The shares of each class represent an interest in the same investment portfolio. Each class has equal rights as to voting, redemption, dividends and liquidation, except that each class bears different distribution expenses and other expenses properly attributable to the particular class as approved by the board of trustees and set forth in the Series' amended and restated rule 18f-3 Plan. Class P1 and P2 shareholders have exclusive voting rights with respect to their respective rule 12b-1 Plan adopted in connection with the distribution of Class P1 and P2. Class P1 and Class P2 shareholders have exclusive voting rights with respect to their respective Insurance Administrative Services Plans. Shares of each class of the Series vote together on matters that affect all classes in substantially the same manner. Each class votes as a class on matters that affect that class alone.

The Series does not hold annual meetings of shareholders. However, significant matters that require shareholder approval, such as certain elections of board members or a change in a fundamental investment policy, will be presented to shareholders at a meeting called for such purpose. Shareholders have one vote per share owned. At the request of the holders of at least 10% of the shares, the Series will hold a meeting at which any member of the board could be removed by a majority vote.

The Series' declaration of trust and by-laws, as well as separate indemnification agreements that the Series has entered into with independent trustees, provide in effect that, subject to certain conditions, the Series will indemnify its officers and trustees against liabilities or expenses actually and reasonably incurred by them relating to their service to the Series. However, trustees are not protected from liability by reason of their willful misfeasance, bad faith, gross negligence or reckless disregard of the duties involved in the conduct of their office.

American Funds Insurance Series – Managed Risk Funds — Page 56

**Leadership structure —** The board's chair is currently an independent trustee who is not an "interested person" of the Series within the meaning of the 1940 Act. The board has determined that an independent chair facilitates oversight and enhances the effectiveness of the board. The independent chair's duties include, without limitation, generally presiding at meetings of the board, approving board meeting schedules and agendas, leading meetings of the independent trustees in executive session, facilitating communication with committee chairs, and serving as the principal independent trustee contact for Series management and counsel to the independent trustees and the fund.

**Risk oversight —** Day-to-day management of the Series, including risk management, is the responsibility of the Series' contractual service providers, including the Series' investment adviser, principal underwriter/distributor, transfer agent and subadviser. Each of these entities is responsible for specific portions of the Series' operations, including the processes and associated risks relating to the fund's investments, integrity of cash movements, financial reporting, operations and compliance. The board of trustees oversees the service providers' discharge of their responsibilities, including the processes they use to manage relevant risks. In that regard, the board receives reports regarding the operations of the Series' service providers, including risks. For example, the board receives reports from investment professionals regarding risks related to the fund's investments and trading. The board also receives compliance reports from the Series and the investment adviser's chief compliance officers addressing certain areas of risk.

Committees of the Series board, which are comprised of independent board members, none of whom is an "interested person" of the fund within the meaning of the 1940 Act, as well as joint committees of independent board members of funds managed by Capital Research and Management Company, also explore risk management procedures in particular areas and then report back to the full board. For example, the Series' audit committee oversees the processes and certain attendant risks relating to financial reporting, valuation of fund assets, and related controls. Similarly, a joint review and advisory committee oversees certain risk controls relating to the fund's transfer agency services.

Not all risks that may affect the Series can be identified or processes and controls developed to eliminate or mitigate their effect. Moreover, it is necessary to bear certain risks (such as investment-related risks) to achieve each fund's objectives. As a result of the foregoing and other factors, the ability of the Series' service providers to eliminate or mitigate risks is subject to limitations.

**Committees of the board of trustees —** The Series has an audit committee comprised of Vanessa C.L. Chang, Francisco G. Cigarroa, John G. Freund, Leslie Stone Heisz, Sharon I Meers, Kenneth M. Simril, Christopher E. Stone and Paul S. Williams. The committee provides oversight regarding the Series' accounting and financial reporting policies and practices, its internal controls and the internal controls of the Series' principal service providers. The committee acts as a liaison between the Series' independent registered public accounting firm and the full board of trustees. The audit committee held five meetings during the 2025 fiscal year.

The Series has a contracts committee comprised of all of its independent board members. The committee's principal function is to request, review and consider the information deemed necessary to evaluate the terms of certain agreements between the Series and its investment adviser or the investment adviser's affiliates, such as the Investment Advisory and Service Agreement and plan of distribution adopted pursuant to rule 12b-1 under the 1940 Act, that the Series may enter into, renew or continue, and to make its recommendations to the full board of trustees on these matters. The contracts committee held one meeting during the 2025 fiscal year.

The Series has a nominating and governance committee comprised of Nariman Farvardin, Jennifer C. Feikin, Margaret Spellings and Alexandra Trower. The committee periodically reviews such issues as the board's composition, responsibilities, committees, compensation and other relevant issues, and recommends any appropriate changes to the full board of trustees. The committee also coordinates annual self-assessments of the board and evaluates, selects and nominates independent

American Funds Insurance Series – Managed Risk Funds — Page 57

------

trustee candidates to the full board of trustees. While the committee normally is able to identify from its own and other resources an ample number of qualified candidates, it will consider shareholder suggestions of persons to be considered as nominees to fill future vacancies on the board. Such suggestions must be sent in writing to the nominating and governance committee of the Series, addressed to the Series' secretary, and must be accompanied by complete biographical and occupational data on the prospective nominee, along with a written consent of the prospective nominee for consideration of his or her name by the committee. The nominating and governance committee held three meetings during the 2025 fiscal year.

**Proxy voting procedures and principles —** The funds' investment adviser, in consultation with the Series' board, has adopted Proxy Voting Procedures and Principles (the "Principles") with respect to voting proxies of securities held by the funds and other funds advised by the investment adviser or its affiliates. The Principles are reasonably designed to ensure that proxies are voted solely in accordance with the financial interest of the clients of the investment adviser or its affiliates and the shareholders of the funds advised or managed by the investment adviser or its affiliates. The complete text of the Principles is available at capitalgroup.com. Final voting authority is held by a committee of the appropriate equity investment division of the investment adviser under authority delegated by the Series' board. Therefore, if more than one fund invests in the same company, they may vote differently on the same proposal. The boards of funds advised by Capital Research and Management Company and its affiliates have established a Joint Proxy Committee ("JPC") composed of independent board members who serve as representatives from each applicable fund board. The JPC's role is to facilitate appropriate oversight of the proxy voting process and provide valuable input on corporate governance and related matters.

The Principles provide an important framework for analysis and decision-making by all funds. However, they are not exhaustive and do not address all potential issues. The Principles provide a certain amount of flexibility so that all relevant facts and circumstances can be considered in connection with every vote. As a result, each proxy received is voted on a case-by-case basis considering the specific circumstances of each proposal. The voting process reflects the funds' understanding of the company's business, its management and its relationship with shareholders over time. In all cases, long-term value creation and the investment objectives and policies of the funds managed by the investment adviser remain the focus.

The investment adviser seeks to vote all U.S. proxies. Proxies for companies outside the United States are also voted where there is sufficient time and information available, taking into account distinct market practices, regulations and laws, and types of proposals presented in each country. Where there is insufficient proxy and meeting agenda information available, the investment adviser will generally vote against such proposals in the interest of encouraging improved disclosure for investors. The investment adviser may not exercise its voting authority if voting would impose costs on clients, including opportunity costs. For example, certain regulators have granted investment limit relief to the investment adviser and its affiliates, conditioned upon limiting voting power to specific voting ceilings. To comply with these voting ceilings, the investment adviser will scale back its votes across all funds and accounts it manages on a pro rata basis based on assets. In addition, certain countries impose restrictions on the ability of shareholders to sell shares during the proxy solicitation period. The investment adviser may choose, due to liquidity issues, not to expose the funds and accounts it manages to such restrictions and may not vote some (or all) shares. Finally, the investment adviser may determine not to recall securities on loan to exercise its voting rights when it determines that the cost of doing so would exceed the benefits to clients or that the vote would not have a material impact on the investment. Proxies with respect to securities on loan through client-directed lending programs are not available to vote and therefore are not voted.

After a proxy statement is received, the investment adviser's stewardship and engagement team prepares a summary of the proposals contained in the proxy statement.

American Funds Insurance Series – Managed Risk Funds — Page 58

------

Investment analysts are generally responsible for making voting recommendations for their investment division on significant votes that relate to companies in their coverage areas. Analysts also have the opportunity to review initial recommendations made by the investment adviser's stewardship and engagement team. Depending on the vote recommendation, a second opinion may be made by a proxy coordinator (an investment professional with experience in corporate governance and proxy voting matters) within the appropriate investment division, based on knowledge of the Principles and familiarity with proxy-related issues. Each of the investment adviser's equity investment divisions has its own proxy voting committee, which is made up of investment professionals within each division. Each division's proxy voting committee retains final authority for voting decisions made by such division. In cases where a fund is co-managed and a security is held by more than one of the investment adviser's equity investment divisions, the divisions may develop different voting recommendations for individual ballot proposals. If this occurs, and if permitted by local market conventions, the fund's position will generally be voted proportionally by divisional holding, according to their respective decisions. Otherwise, the outcome will be determined by the equity investment division or divisions with the larger position in the security as of the record date for the shareholder meeting.

In addition to our proprietary proxy voting, governance and executive compensation research, Capital Research and Management Company may utilize research provided by third-party advisory firms on a case-by-case basis. It does not, as a policy, follow the voting recommendations provided by these firms. It periodically assesses the information provided by the advisory firms and reports to the applicable governance committees that provide oversight of the application of the Principles.

From time to time the investment adviser may vote proxies issued by, or on proposals sponsored or publicly supported by *(a)* a client with substantial assets managed by the investment adviser or its affiliates, *(b)* an entity with a significant business relationship with The Capital Group Companies, Inc. or its affiliates, or *(c)* a company with a director of an American Fund on its board (each referred to as an "Interested Party"). Other persons or entities may also be deemed an Interested Party if facts or circumstances appear to give rise to a potential conflict.

The investment adviser has developed procedures to identify and address instances when a vote could appear to be influenced by such a relationship. Each equity investment division of the investment adviser has established a Special Review Committee ("SRC") of senior investment professionals and legal and compliance professionals with oversight of potentially conflicted matters.

If a potential conflict is identified according to the procedure above, the SRC will take appropriate steps to address the conflict of interest. These steps may include engaging an independent third party to review the proxy and using the Principles to provide an independent voting recommendation to the investment adviser for vote execution. The investment adviser will generally follow the third party's recommendation, except when it believes the recommendation is inconsistent with the investment adviser's fiduciary duty to its clients. Occasionally, it may not be feasible to engage the third party to review the matter due to compressed timeframes or other operational issues. In this case, the SRC will take appropriate steps to address the conflict of interest, including reviewing the proxy after being provided with a summary of any relevant communications with the Interested Party, the rationale for the voting decision, information on the organization's relationship with the Interested Party and any other pertinent information.

Information regarding how the funds voted proxies relating to portfolio securities during the 12-month period ended June 30 of each year will be available on or about September 1 of such year (*a*) without charge, upon request by calling American Funds Service Company at (800) 421-4225, (*b*) on the Capital Group website and (*c*) on the SEC's website at sec.gov.

American Funds Insurance Series – Managed Risk Funds — Page 59

------

The following summary sets forth the general positions of the investment adviser on various proposals. A copy of the full Principles is available upon request, free of charge, by calling American Funds Service Company or visiting the Capital Group website.

**Director matters —** The election of a company's slate of nominees for director generally is supported. Votes may be withheld for some or all of the nominees if this is determined to be in the best interest of shareholders or if, in the opinion of the investment adviser, such nominee has not fulfilled his or her fiduciary duty. In making this determination, the investment adviser considers, among other things, a nominee's potential conflicts of interest, track record (whether in the current board seat or in previous executive or director roles) with respect to shareholder protection and value creation as well as their capacity for full engagement on board matters. The investment adviser generally supports a breadth of experience and perspectives among board members, and the separation of the chairman and CEO positions.

**Governance provisions —** Proposals to declassify a board (elect all directors annually) generally are supported based on the belief that this increases the directors' sense of accountability to shareholders. Proposals for cumulative voting generally are supported in order to promote management and board accountability and an opportunity for leadership change. Proposals designed to make director elections more meaningful, either by requiring a majority vote or by requiring any director receiving more withhold votes than affirmative votes to tender his or her resignation, generally are supported.

**Shareholder rights —** Proposals to repeal an existing poison pill generally are supported. (There may be certain circumstances, however, when a proxy voting committee of a fund or an investment division of the investment adviser believes that a company needs to maintain anti-takeover protection.) Proposals to eliminate the right of shareholders to act by written consent or to take away a shareholder's right to call a special meeting typically are not supported.

**Compensation and benefit plans —** Equity incentive plans are complicated, and many factors are considered in evaluating a plan. Each plan is evaluated based on protecting shareholder interests and a knowledge of the company and its management. Considerations include the pricing (or repricing) of options awarded under the plan and the impact of dilution on existing shareholders from past and future equity awards. Compensation packages should be structured to attract, motivate and retain existing employees and qualified directors; in addition, they should be aligned with the long-term success of the company and the enhancement of shareholder value.

**Routine matters —** The ratification of auditors, procedural matters relating to the annual meeting and changes to company name are examples of items considered routine. Such items generally are voted in favor of management's recommendations unless circumstances indicate otherwise.

**Shareholder proposals on environmental and social issues —** The investment adviser believes environmental and social issues present investment risks and opportunities that can shape a company's long-term financial sustainability. Shareholder proposals, including those relating to social and environmental issues, are evaluated in terms of their materiality to the company and its ability to generate long-term value in light of the company's business model specific operating context. The investment adviser generally supports transparency and standardized disclosure, particularly that which leverages existing regulatory reporting or industry best practices. With respect to environmental matters, this includes disclosures aligned with industry standards and reporting on sustainability issues that are material to investment analysis. With respect to social matters, the investment adviser encourages companies to disclose the composition of the workforce in a regionally appropriate manner. The investment

adviser supports relevant reporting and disclosure that is consistent with broadly applicable standards.

**Principal fund shareholders —** The following table identifies those investors who own of record, or are known by the Series to own beneficially, 5% or more of any class of a fund's shares as of the opening of business on [date], 2024. Unless otherwise indicated, the ownership percentages below represent ownership of record rather than beneficial ownership.

**Investment adviser —** Capital Research and Management Company, the Series' investment adviser, founded in 1931, maintains research facilities in the United States and abroad (Geneva, Hong Kong, London, Los Angeles, Mumbai, New York, San Francisco, Singapore, Tokyo, Toronto and Washington, D.C.). These facilities are staffed with experienced investment professionals. The investment adviser is located at 333 South Hope Street, Los Angeles, CA 90071. It is a wholly owned subsidiary of The Capital Group Companies, Inc., a holding company for several investment management subsidiaries. Capital Research and Management Company manages equity assets through three equity investment divisions and fixed income assets through its fixed income investment division, Capital Fixed Income Investors. The three equity investment divisions — Capital World Investors, Capital Research Global Investors and Capital International Investors — make investment decisions independently of one another. Portfolio managers in Capital International Investors rely on a research team that also provides investment services to institutional clients and other accounts advised by affiliates of Capital Research and Management Company.

The investment adviser has adopted policies and procedures that address issues that may arise as a result of an investment professional's management of the fund and other funds and accounts. Potential issues could involve allocation of investment opportunities and trades among funds and accounts, use of information regarding the timing of fund trades, investment professional compensation and voting relating to portfolio securities. The investment adviser believes that its policies and procedures are reasonably designed to address these issues.

The investment adviser has designed policies and procedures reasonably designed to ensure that the subadviser complies with the fund's investment objective, strategies and restrictions and provides oversight and monitoring of the subadviser's activities and compliance procedures.

**Subadviser —** Milliman Financial Risk Management LLC is the subadviser to the fund with respect to the managed risk strategy. Milliman Financial Risk Management LLC is a wholly owned subsidiary of Milliman, Inc. and is located at 71 South Wacker Drive, 31st Floor, Chicago, IL 60606.

**Compensation of investment professionals —** Portfolio managers and investment analysts of the investment adviser are paid competitive salaries by Capital Research and Management Company. In addition, they may receive bonuses based on their individual portfolio results for the underlying fund in which the fund invests, as well as qualitative considerations, such as an individual's contribution to the organization, which would include service as a portfolio manager to the fund. Investment professionals also may participate in profit-sharing plans. The relative mix of compensation represented by bonuses, salary and profit-sharing plans will vary depending on the individual's portfolio results, contributions to the organization and other factors.

Portfolio managers of the subadviser are paid competitive salaries by Milliman Financial Risk Management LLC. In addition, they may receive bonuses based on qualitative considerations, such as an individual's contribution to the organization, and performance reviews in relation to job responsibilities. Investment professionals also may participate in profit-sharing plans. The relative mix of compensation represented by bonuses, salary and profit-sharing plans will vary depending on the individual's contributions to the organization and other factors.

**Portfolio manager fund holdings and management of other accounts —** Shares of the fund may only be owned by purchasing variable annuity and variable life insurance contracts. Each portfolio manager's need for variable annuity or variable life insurance contracts and the role those contracts would play in his or her comprehensive investment portfolio will vary and depend on a number of factors including tax, estate planning, life insurance, alternative retirement plans or other considerations. The portfolio managers have determined that variable insurance or annuity contracts do not meet their current needs. Consequently, they do not hold shares of the funds.

Portfolio managers may also manage assets in other registered investment companies advised by Capital Research and Management Company or its affiliates. Other managed accounts as of the end of the Series' most recently completed fiscal year are listed as follows:

The fund's investment adviser has adopted policies and procedures to mitigate material conflicts of interest that may arise in connection with a portfolio manager's management of the fund, on the one hand, and investments in the other pooled investment vehicles and other accounts, on the other hand, such as material conflicts relating to the allocation of investment opportunities that may be suitable for both the fund and such other accounts.

**Investment Advisory and Service Agreement —** The Investment Advisory and Service Agreement (the "Agreement") between the Series and the investment adviser will continue in effect until April 30, 2027, unless sooner terminated, and may be renewed from year to year thereafter, provided that any such renewal has been specifically approved at least annually by (*a*) the board of trustees, or by the vote of a majority (as defined in the 1940 Act) of the outstanding voting securities of the applicable Series, and (*b*) the vote of a majority of trustees who are not parties to the Agreement or interested persons (as defined in the 1940 Act) of any such party, in accordance with applicable laws and regulations. The Agreement provides that the investment adviser has no liability to the Series for its acts or omissions in the performance of its obligations to the Series not involving willful misconduct, bad faith, gross negligence or reckless disregard of its obligations under the Agreement. The Agreement also provides that either party has the right to terminate it, without penalty, upon 60 days' written notice to the other party, and that the Agreement automatically terminates in the event of its assignment (as defined in the 1940 Act). In addition, the Agreement provides that the investment adviser may delegate all, or a portion of, its investment management responsibilities to one or more subadvisers approved by the Series' board and the shareholders of each applicable fund. Any such subadviser will be paid solely by the investment adviser out of the investment adviser's fees.

In addition to providing investment advisory services, the investment adviser furnishes the services and pays the compensation and travel expenses of qualified persons to perform the executive and related administrative functions of the Series, and provides necessary office space, office equipment and utilities, and general purpose accounting forms, supplies and postage used at the office of the Series relating to the services furnished by the investment adviser. Subject to the expense agreement described below, the Series will pay all expenses not expressly assumed by the investment adviser, including, but not limited to: registration and filing fees of federal and state agencies; blue sky expenses (if any); expenses of shareholders' meetings; the expense of reports to existing shareholders; expenses of printing proxies and prospectuses; insurance premiums; legal and auditing fees; fund accounting fees; dividend disbursement expenses; the expense of the issuance, transfer and redemption of its shares; custodian fees; printing and preparation of registration statements; taxes; compensation, fees and expenses paid to trustees unaffiliated with the investment adviser; association dues; and costs of stationary and forms prepared exclusively for the Series.

The investment adviser is currently reimbursing a portion of the expenses of Managed Risk EUPAC Fund. This reimbursement will be in effect through at least May 1, 2027. The adviser may elect at its discretion to extend, modify or terminate the reimbursements at that time. For each of the fiscal years ended December 31, 2025, 2024 and 2023, the total expenses reimbursed by the investment adviser were $39,000, $47,000 and $59,000, respectively.

For the fiscal years ended December 31, 2025, 2024 and 2023, the investment adviser earned from the fund management fees. The investment adviser waived a portion of its investment advisory services fees for each share class of the fund, such that the fees which were equivalent to an annualized rate of .15% of average daily net assets were reduced to .10% of average daily net assets. This waiver may only be modified or terminated with the approval of the Series' board. After giving effect to the fee waiver described above, each fund paid the following investment advisory services fees:

**Sub-Advisory Agreement —** The subadviser is appointed by the Series and the investment adviser, and provides services, pursuant to a Sub-Advisory Agreement. The Sub-Advisory Agreement between the investment adviser, the Series and the subadviser will continue in effect until April 30, 2027, unless sooner terminated, and may be renewed from year to year thereafter, provided that any such renewal has been specifically approved at least annually by (*a*) the board of trustees, or by the vote of a majority (as defined in the 1940 Act) of the outstanding voting securities of the applicable Series, and (*b*) the vote of a majority of trustees who are not parties to the Sub-Advisory Agreement or interested persons (as defined in the 1940 Act) of any such party, cast in person at a meeting called for the purpose of voting on such approval. The Sub-Advisory Agreement also provides that either party has the right to terminate it, without penalty, upon 60 days' written notice to the other party, and that the Sub-Advisory Agreement automatically terminates in the event of its assignment (as defined in the 1940 Act) or the assignment or termination of the Investment Advisory and Service Agreement. In addition, the Sub-Advisory Agreement provides that the subadviser will be paid solely by the investment adviser out of the investment adviser's fees.

American Funds Insurance Series – Managed Risk Funds — Page 68

**Administrative services —** The investment adviser and its affiliates provide certain administrative services for shareholders of the Series' Class P1 and P2 shares. Administrative services are provided by the investment adviser and its affiliates to help assist third parties providing non-distribution services to fund shareholders. These services include providing in-depth information on the fund and market developments that impact fund investments. Administrative services also include, but are not limited to, coordinating, monitoring and overseeing third parties that provide services to Series shareholders.

These services are provided pursuant to an Administrative Services Agreement (the "Administrative Agreement") between the Series and the investment adviser relating to the Series' Class P1 and P2 shares. The Administrative Agreement will continue in effect until April 30, 2027, unless sooner renewed or terminated, and may be renewed from year to year thereafter, provided that any such renewal has been specifically approved by the vote of a majority of the members of the Series' board who are not parties to the Administrative Agreement or interested persons (as defined in the 1940 Act) of any such party. The Series may terminate the Administrative Agreement at any time by vote of a majority of independent board members. The investment adviser has the right to terminate the Administrative Agreement upon 60 days' written notice to the Series. The Administrative Agreement automatically terminates in the event of its assignment (as defined in the 1940 Act).

The fund is not assessed an administrative services fee for administrative services provided under the Administrative Agreement. However, the investment adviser receives an administrative services fee at the annual rate of .03% of the average daily net assets from the Class 1 shares of the underlying funds (which could be increased as described in the current prospectus of the applicable underlying funds) for its provision of administrative services. Administrative services fees are paid monthly and accrued daily.

**Plans of distribution —** The Series has adopted plans of distribution (the "Plans") for its Class P1 and P2 shares, pursuant to rule 12b-1 under the 1940 Act. As required by rule 12b-1, the Plans have been approved by a majority of the entire board of trustees, and separately by a majority of the trustees who are not "interested persons" of the Series and who have no direct or indirect financial interest in the operation of the Plans. Potential benefits of the Plans to the Series include improved shareholder services, benefits to the investment process from growth or stability of assets and maintenance of a financially healthy management organization. The selection and nomination of trustees who are not "interested persons" of the Series is committed to the discretion of the trustees who are not "interested persons" during the existence of the Plans. The Plans are reviewed quarterly and must be renewed annually by the board of trustees.

Under the Plans, the Series may expend up to .25% of the assets of Class P1 shares and up to .50% of the assets of Class P2 shares. The board of trustees has authorized the Series to pay to insurance company contract issuers .25% of the fund's average net assets of Class P2 shares annually to finance any distribution activity which is primarily intended to benefit the Class P2 shares of the fund, provided that the board of trustees of the Series has approved the categories of expenses for which payment is being made. The board of trustees has not authorized any payments on Class P1 assets pursuant to the Plan for Class P1 shares. Payments made pursuant to the Plans will be used by insurance company contract issuers to pay a continuing annual service fee to dealers on the value of all variable annuity and variable life insurance contract payments for account-related services provided to existing shareholders. During the fiscal year ended December 31, 2025, the Series incurred distribution expenses of $7,656,000 payable to certain life insurance companies under the respective Plans. Accrued and unpaid distribution expenses were $559,000.

**Insurance administration fee —** The insurance companies for which the fund's Class P1 and P2 shares are available provide certain administrative services for the separate accounts that hold the shares of the fund and the contractholders for which the shares of the fund are beneficially owned as underlying investments of such contractholders annuities. These services include, but are not limited to, record maintenance, shareholder communications and transactional services.

These services are provided pursuant to an Insurance Administrative Services Plan adopted by the Series relating to the fund's Class P1 and P2 shares. Under this agreement, the insurance company receives .25% of the fund's average daily net assets attributable to the appropriate share class. During the fiscal year ended December 31, 2025, the Series incurred insurance administration fees of $4,699,000 for Class P1 shares and $7,656,000 for Class P2 shares.

**Execution of portfolio transactions**

The fund does not incur any brokerage commissions for purchasing shares of the underlying fund. However, the fund may incur brokerage commissions and/or investment dealer concessions when purchasing short-term debt securities. Portfolio transactions for the fund may be executed as part of concurrent authorizations to purchase or sell the same security for other funds served by the investment adviser, or for trusts or other accounts served by affiliated companies of the investment adviser. When such concurrent authorizations occur, the objective is to allocate the executions in an equitable manner.

Specific decisions to purchase or sell futures contracts for the fund are made by the portfolio managers of the subadviser. Purchases and sales of futures contracts for the fund will be effected through executing brokers and FCMs that specialize in the types of futures contracts that the fund expects to hold. The investment adviser will use reasonable efforts to choose executing brokers and FCMs capable of providing the services necessary to obtain the most favorable price and execution available. The full range and quality of services available will be considered in making these determinations. The subadviser and investment adviser will monitor the executing brokers and FCMs used for purchases and sales of futures contracts for their ability to execute trades based on many factors, such as the size of the orders, the difficulty of executions, the operational facilities of the firm involved and other factors.

The Series is required to disclose information regarding investments in the securities of its "regular" broker-dealers (or parent companies of its regular broker-dealers) that derive more than 15% of their revenue from broker-dealer, underwriter or investment adviser activities. A regular broker-dealer is (*a*) one of the 10 broker-dealers that received from the Series the largest amount of brokerage commissions by participating, directly or indirectly, in the Series' portfolio transactions during the Series' most recently completed fiscal year; (*b*) one of the 10 broker-dealers that engaged as principal in the largest dollar amount of portfolio transactions of the Series during the Series' most recently completed fiscal year; or (*c*) one of the 10 broker-dealers that sold the largest amount of securities of the Series during the Series' most recently completed fiscal year.

At the end of the Series' most recent fiscal year, the Series did not have investments in securities of any of its regular broker-dealers.

| Managed Risk Asset Allocation Fund | 23000 | 10000 | 10000 | 45000 |

Changes in the dollar amount of brokerage commissions paid by each fund over the last three fiscal years resulted from changes in the volume of trading activity.

For information regarding the policies with respect to the execution of portfolio transactions of the underlying fund, please see the statement of additional information for the underlying fund.

American Funds Insurance Series – Managed Risk Funds — Page 72

**Disclosure of portfolio holdings**

The Series' investment adviser, on behalf of the funds, has adopted policies and procedures with respect to the disclosure of information about the funds' portfolio securities. These policies and procedures have been reviewed by the Series' board of trustees, and compliance will be periodically assessed by the board in connection with reporting from the Series' Chief Compliance Officer.

Under these policies and procedures, each fund's complete list of portfolio holdings available for public disclosure, dated as of the end of each calendar month, is permitted to be posted on the Capital Group website (capitalgroup.com/afis) by the 10th day after such calendar month. In practice, the publicly disclosed portfolio is typically posted on the Capital Group website within 30 days after the end of the calendar month. The publicly disclosed portfolio may exclude certain securities when deemed to be in the best interest of the fund as permitted by applicable regulations. Such portfolio holdings information may be disclosed to any person pursuant to an ongoing arrangement to disclose portfolio holdings information to such person no earlier than one day after the day on which the information is posted on the Capital Group website. The investment adviser may disclose individual holdings more frequently on the Capital Group website if it determines it is in the best interest of the fund.

Certain intermediaries are provided additional information about the fund's management team, including information on the fund's portfolio securities they have selected. This information is provided to larger intermediaries that require the information to make the fund available for investment on the firm's platform. Intermediaries receiving the information are required to keep it confidential and use it only to analyze the fund.

The Series' custodian, outside counsel, auditor, financial printers, proxy voting and class action claims processing service providers, pricing information vendors, consultants or agents operating under a contract with the investment adviser or its affiliates, co-litigants (such as in connection with a bankruptcy proceeding related to a fund holding) and certain other third parties described below, each of which requires portfolio holdings information for legitimate business and fund oversight purposes, may receive fund portfolio holdings information earlier. See the "General information" section in this statement of additional information for further information about the Series' custodian, outside counsel and auditor.

Each fund's portfolio holdings, dated as of the end of each calendar month, are made available to insurance companies that use the funds as underlying investments in their variable annuity contracts and variable life insurance policies. Monthly holdings are made available to help the insurance companies evaluate the funds for inclusion in the contracts and life insurance policies they offer and to evaluate and manage the insurance guarantees offered under their insurance contracts. Monthly holdings may be provided to insurance companies no earlier than the 10th day after the end of the calendar month. In practice, monthly holdings are provided within 30 days after the end of the calendar month. Monthly holdings may also be provided to the fund's subadviser. Insurance companies may receive a list of the futures contracts and other investments that make up a fund's managed risk strategy each business day. Holdings may also be disclosed more frequently to certain statistical and data collection agencies including Morningstar, Lipper, Inc., Value Line, Vickers Stock Research, Bloomberg and Thomson Financial Research. Information on certain portfolio characteristics of the funds and underlying funds are also provided to the insurance companies and the fund's subadviser each business day.

Affiliated persons of the Series, including officers of the Series and employees of the investment adviser and its affiliates, who receive portfolio holdings information are subject to restrictions and limitations on the use and handling of such information pursuant to applicable codes of ethics, including requirements not to trade in securities based on confidential and proprietary investment

American Funds Insurance Series – Managed Risk Funds — Page 73

------

information, to maintain the confidentiality of such information, and to pre-clear securities trades and report securities transactions activity, as applicable. For more information on these restrictions and limitations, please see the "Code of ethics" section in this statement of additional information and the Code of Ethics. Third-party service providers of the Series and other entities, as described in this statement of additional information, receiving such information are subject to confidentiality obligations and obligations that would prohibit them from trading in securities based on such information. When portfolio holdings information is disclosed other than through the Capital Group website to persons not affiliated with the Series, such persons will be bound by agreements (including confidentiality agreements) or fiduciary or other obligations that restrict and limit their use of the information to legitimate business uses only. None of the Series, its investment adviser or any of their affiliates receives compensation or other consideration in connection with the disclosure of information about portfolio securities.

Subject to board policies, the authority to disclose a fund's portfolio holdings, and to establish policies with respect to such disclosure, resides with the appropriate investment-related committees of the Series' investment adviser. In exercising their authority, the committees determine whether disclosure of information about the funds' portfolio securities is appropriate and in the best interest of fund shareholders. The investment adviser has implemented policies and procedures to address conflicts of interest that may arise from the disclosure of fund holdings. For example, the investment adviser's code of ethics specifically requires, among other things, the safeguarding of information about fund holdings and contains prohibitions designed to prevent the personal use of confidential, proprietary investment information in a way that would conflict with fund transactions. In addition, the investment adviser believes that its current policy of not selling portfolio holdings information and not disclosing such information to unaffiliated third parties until such holdings have been made public on the Capital Group website (other than to certain Series service providers and other third parties for legitimate business and fund oversight purposes) helps reduce potential conflicts of interest between fund shareholders and the investment adviser and its affiliates.

The Series' investment adviser and its affiliates provide investment advice to individuals and financial intermediaries that have investment objectives that may be substantially similar to those of the funds. These clients also may have portfolios consisting of holdings substantially similar to those of the funds and generally have access to current portfolio holdings information for their accounts. These clients do not owe the Series' investment adviser or the funds a duty of confidentiality with respect to disclosure of their portfolio holdings.

**Price of shares**

Shares are purchased at the offering price or sold at the net asset value price next determined after the purchase or sell order is received and accepted by the Series or its designee. Orders received by the Series or authorized designee after the time of the determination of the net asset value will be entered at the next calculated offering price.

The price you pay for shares, the offering price, is based on the net asset value per share. Net asset value is computed by adding the value of a fund's investments, cash or other assets, subtracting the fund's liabilities, and dividing the result by the number of shares that are outstanding. Realized investment income and gain is included in the fund's net asset value until the ex-dividend date, when the declared dividend amount is treated as a fund liability. The net asset value is calculated once daily as of the close of regular trading on the New York Stock Exchange, normally 4 p.m. New York time, each day the New York Stock Exchange is open. If the New York Stock Exchange makes a scheduled (e.g., the day after Thanksgiving) or an unscheduled close prior to 4 p.m. New York time, the net asset value of the fund will be determined at approximately the time the New York Stock Exchange closes on that day. If on such a day market quotations and prices from third-party pricing services are not based as of the time of the early close of the New York Stock Exchange but are as of a later time (up to approximately 4 p.m. New York time), for example because the market remains open after the close of the New York Stock Exchange, those later market quotations and prices will be used in determining the fund's net asset value.

Orders in good order received after the New York Stock Exchange closes (scheduled or unscheduled) will be processed at the net asset value (plus any applicable sales charge) calculated on the following business day. The New York Stock Exchange is currently closed on weekends and on the following holidays: New Year's Day; Martin Luther King Jr. Day; Presidents' Day; Good Friday; Memorial Day; Juneteenth National Independence Day; Independence Day; Labor Day; Thanksgiving Day; and Christmas Day. Each share class of the fund has a separately calculated net asset value (and share price). The fund's investment adviser delivers the net asset value every day it is calculated to each insurance company that offers such fund as an underlying investment to its variable contracts by, for example, email, direct electronic transmission or facsimile or through the systems of the National Securities Clearing Corporation.

As noted in the fund's prospectus, the principal assets of the fund consists of investments in the underlying fund and exchange-traded futures and put options.

Exchange-traded options and futures are generally valued at the official closing price for options and official settlement price for futures on the exchange or market on which such instruments are traded, as of the close of business on the day such instruments are being valued or, lacking any sales, at the last available bid price. Prices for each security are taken from the principal exchange or market on which the security trades.

The investments in the underlying fund are reflected in the net assets of the fund on the day of investment. All portfolio securities of the underlying fund are valued, and the net asset values per share for each share class are determined, as indicated below.

The underlying fund is priced based on the net asset value of the underlying fund, calculated as of the close of regular trading on the New York Stock Exchange, normally 4 p.m. New York time, each day the New York Stock Exchange is open. Equity securities, including depositary receipts, exchange-traded funds, and certain convertible preferred stocks that trade on an exchange or market, are generally valued at the official closing price of, or the last reported sale price on, the exchange or market on which such securities are traded, as of the close of business on the day the securities are

being valued or, lacking any sales, at the last available bid price. Prices for each security are taken from the principal exchange or market on which the security trades.

Fixed income securities, including short-term securities, are generally valued at evaluated prices obtained from third-party pricing vendors. Vendors value such securities based on one or more inputs that may include, among other things, benchmark yields, transactions, bids, offers, quotations from dealers and trading systems, new issues, underlying equity of the issuer, interest rate volatilities, spreads and other relationships observed in the markets among comparable securities and proprietary pricing models such as yield measures calculated using factors such as cash flows, prepayment information, default rates, delinquency and loss assumptions, financial or collateral characteristics or performance, credit enhancements, liquidation value calculations, specific deal information and other reference data.

Forward currency contracts are valued based on the spot and forward exchange rates obtained from a third-party pricing vendor.

Futures contracts are generally valued at the official settlement price of, or the last reported sale price on, the principal exchange or market on which such instruments are traded, as of the close of business on the day the contracts are being valued or, lacking any sales, at the last available bid price.

Swaps, including interest rate swaps, total return swaps and positions in credit default swap indices, are generally valued using evaluated prices obtained from third-party pricing vendors who calculate these values based on market inputs that may include yields of the indices referenced in the instrument and the relevant curve, dealer quotes, default probabilities and recovery rates, other reference data, and terms of the contract.

Options are valued using market quotations or valuations provided by one or more pricing vendors. Similar to futures, options may also be valued at the official settlement price if listed on an exchange.

Securities and other assets for which representative market quotations are not readily available or are considered unreliable by the investment adviser are valued at fair value as determined in good faith under fair value guidelines adopted by the investment adviser and approved by the Series' board. Subject to board oversight, the Series' board has designated the fund's investment adviser to make fair valuation determinations, which are directed by a valuation committee established by the fund's investment adviser. The board receives regular reports describing fair-valued securities and the valuation methods used.

As a general principle, these guidelines consider relevant company, market and other data and considerations to determine the price that the fund might reasonably expect to receive if such fair valued securities were sold in an orderly transaction. Fair valuations may differ materially from valuations that would have been used had greater market activity occurred. The investment adviser's valuation committee considers relevant indications of value that are reasonably and timely available to it in determining the fair value to be assigned to a particular security, such as the type and cost of the security, restrictions on resale of the security, relevant financial or business developments of the issuer, actively traded similar or related securities and transactions, dealer or broker quotes, conversion or exchange rights on the security, related corporate actions, significant events occurring after the close of trading in the security and changes in overall market conditions. The valuation committee employs additional fair value procedures to address issues related to equity securities that trade principally in markets outside the United States. Such securities may trade in markets that open and close at different times, reflecting time zone differences. If significant events occur after the close of a market (and before the fund's net asset values are next determined) which affect the value of equity securities held in the fund's portfolio, appropriate adjustments from closing market prices may be made to

American Funds Insurance Series – Managed Risk Funds — Page 76

------

reflect these events. Events of this type could include, for example, earthquakes and other natural disasters or significant price changes in other markets (e.g., U.S. stock markets).

Assets and liabilities, including investment securities, denominated in currencies other than U.S. dollars are translated into U.S. dollars, prior to the next determination of the net asset value of the fund's shares, at the exchange rates obtained from a third-party pricing vendor.

Each class of shares represents interests in the same portfolio of investments and is identical in all respects to each other class, except for differences relating to distribution, service and other charges and expenses, certain voting rights, differences relating to eligible investors, the designation of each class of shares, conversion features and exchange privileges. Expenses attributable to the fund, but not to a particular class of shares, are borne by each class pro rata based on the relative aggregate net assets of the classes. Expenses directly attributable to a class of shares are borne by that class of shares. Liabilities attributable to particular share classes, such as liabilities for repurchases of fund shares, are deducted from total assets attributable to such share classes.

Net assets so obtained for each share class are then divided by the total number of shares outstanding of that share class, and the result, rounded to the nearest cent, is the net asset value per share for that class.

**Taxes and distributions**

**Taxation as a regulated investment company** — The Series intends to qualify each year as a "regulated investment company" under Subchapter M of the Internal Revenue Code ("Code") so that it will not be liable for federal tax on income and capital gains distributed to shareholders. In order to qualify as a regulated investment company, and avoid being subject to federal income taxes, the Series intends to distribute substantially all of its net investment income and realized net capital gains on a fiscal year basis, and intends to comply with other tests applicable to regulated investment companies under Subchapter M, including the asset diversification test. The asset diversification test requires that at the close of each quarter of the Series' taxable year that (i) at least 50% of the Series' assets be invested in cash and cash items, government securities, securities of other funds and other securities which, with respect to any one issuer, represent neither more than 5% of the assets of the Series nor more than 10% of the voting securities of the issuer, and (ii) no more than 25% of the Series' assets be invested in the securities of any one issuer (other than government securities or the securities of other funds), the securities (other than the securities of other funds) of two or more issuers that the Series controls and are engaged in similar trades or businesses, or the securities of one or more qualified publicly traded partnerships.

The Code includes savings provisions allowing the Series to cure inadvertent failures of certain qualification tests required under Subchapter M. However, should the Series fail to qualify under Subchapter M, the Series would be subject to federal, and possibly state, corporate taxes on its taxable income and gains.

The Series is subject to a set of asset diversification requirements applicable to insurance company separate accounts and their underlying funding vehicles. To satisfy these diversification requirements, as of the end of each calendar quarter or within 30 days thereafter, the Series must (*a*) be qualified as a "regulated investment company"; and (*b*) have either (*i*) no more than 55% of the total value of its assets in cash and cash equivalents, government securities and securities of other regulated investment companies; or (*ii*) no more than 55% of its total assets represented by any one investment, no more than 70% by any two investments, no more than 80% by any three investments, and no more than 90% by any four investments. For this purpose all securities of the same issuer are considered a single investment, and each agency or instrumentality of the U.S. government is treated as a separate issuer of securities. The Series intends to comply with these regulations. If the Series should fail to comply with these regulations, Contracts invested in the Series will not be treated as annuity, endowment or life insurance contracts under the Code.

The Series may declare a capital gain distribution consisting of the excess of net realized long-term capital gains over net realized short-term capital losses. Net capital gains for a fiscal year are computed by taking into account any capital loss carryforward of the Series.

Certain distributions reported by the Series as Section 163(j) interest dividends may be treated as interest income by shareholders for purposes of the tax rules applicable to interest expense limitations under Section 163(j) of the Code. Such treatment by the shareholder is generally subject to holding period requirements and other potential limitations, although the holding period requirements are generally not applicable to dividends declared by money market funds and certain other funds that declare dividends daily and pay such dividends on a monthly or more frequent basis. The amount that the Series is eligible to report as a Section 163(j) dividend for a tax year is generally limited to the excess of the Series' business interest income over the sum of the Series' (i) business interest expense and (ii) other deductions properly allocable to the Series' business interest income.

**Tax consequences of investing in non-U.S. securities —** Dividend and interest income received by the Series from sources outside the United States may be subject to withholding and other taxes imposed by such foreign jurisdictions. Tax conventions between certain countries and the United States,

American Funds Insurance Series – Managed Risk Funds — Page 78

------

however, may reduce or eliminate these foreign taxes. Some foreign countries impose taxes on capital gains with respect to investments by foreign investors.

Foreign currency gains and losses, including the portion of gain or loss on the sale of debt securities attributable to fluctuations in foreign exchange rates, are generally taxable as ordinary income or loss. These gains or losses may increase or decrease the amount of dividends payable by the Series to shareholders. The Series may elect to treat gain and loss on certain foreign currency contracts as capital gain and loss instead of ordinary income or loss.

**Tax consequences of investing in derivatives** — The Series may enter into transactions involving derivatives, such as futures, swaps, options and forward contracts. Special tax rules may apply to these types of transactions that could defer losses to the Series, accelerate the Series' income, alter the holding period of certain securities or change the classification of capital gains. These tax rules may therefore impact the amount, timing and character of fund distributions.

**Discount —** Certain bonds acquired by the fund, such as zero coupon bonds, may be treated as bonds that were originally issued at a discount. Original issue discount represents interest for federal income tax purposes and is generally defined as the difference between the price at which a bond was issued (or the price at which it was deemed issued for federal income tax purposes) and its stated redemption price at maturity. Original issue discount is treated for federal income tax purposes as tax exempt income earned by a fund over the term of the bond, and therefore is subject to the distribution requirements of the Code. The annual amount of income earned on such a bond by a fund generally is determined on the basis of a constant yield to maturity which takes into account the semiannual compounding of accrued interest (including original issue discount). Certain bonds acquired by the fund may also provide for contingent interest and/or principal. In such a case, rules similar to those for original issue discount bonds would require the accrual of income based on an assumed yield that may exceed the actual interest payments on the bond.

Some of the bonds may be acquired by a fund on the secondary market at a discount which exceeds the original issue discount, if any, on such bonds. This additional discount constitutes market discount for federal income tax purposes. Any gain recognized on the disposition of any bond having market discount generally will be treated as taxable ordinary income to the extent it does not exceed the accrued market discount on such bond (unless a fund elects to include market discount in income in the taxable years to which it is attributable). Realized accrued market discount on obligations that pay tax-exempt interest is nonetheless taxable. Generally, market discount accrues on a daily basis for each day the bond is held by a fund at a constant rate over the time remaining to the bond's maturity. In the case of any debt instrument having a fixed maturity date of not more than one year from date of issue, the gain realized on disposition will be treated as short-term capital gain. Some of the bonds acquired by a fund with a fixed maturity date of one year or less from the date of their issuance may be treated as having original issue discount or, in certain cases, "acquisition discount" (generally, the excess of a bond's stated redemption price at maturity over its acquisition price). A fund will be required to include any such original issue discount or acquisition discount in taxable ordinary income. The rate at which such acquisition discount and market discount accrues, and is thus included in a fund's investment company taxable income, will depend upon which of the permitted accrual methods the fund elects.

**General information**

**Custodian of assets —** Securities and cash owned by the fund, including proceeds from the sale of shares of the funds and of securities in the funds' portfolio, are held by State Street Bank and Trust Company, One Lincoln Street, Boston, MA 02111, as custodian. Non-U.S. securities may be held by the custodian in non-U.S. banks or securities depositories or foreign branches of U.S. banks.

**Transfer agent services —** American Funds Service Company, a wholly owned subsidiary of the investment adviser, maintains the records of each insurance company's separate account, processes purchases and redemptions of the funds' shares, acts as dividend and capital gain distribution disbursing agent, and performs other related shareholder service functions. The principal office of American Funds Service Company is located at 6455 Irvine Center Drive, Irvine, CA 92618. Transfer agent fees are paid according to a fee schedule, based on the number of accounts serviced, contained in a Shareholder Services Agreement between the Series and American Funds Service Company. American Funds Service Company was paid a transfer agent fee of less than $1,000 for Class P1 shares and less than $1,000 for Class P2 shares for the 2025 fiscal year.

**Independent registered public accounting firm —** During the fiscal year ended December 31, 2025, PricewaterhouseCoopers LLP ("PwC"), 601 South Figueroa Street, Los Angeles, CA 90017, served as the Series' independent registered public accounting firm, providing audit services, preparation of tax returns and review of certain documents to be filed with the SEC. The financial statements and financial highlights of the Series included in this statement of additional information that are from the Series' Form N-CSR for the most recent fiscal year have been audited by PwC, an independent registered public accounting firm, as stated in their report appearing herein. Such financial statements and financial highlights are included in reliance upon the report of such firm given upon their authority as experts in accounting and auditing. The selection of the Series' independent registered public accounting firm is reviewed and determined annually by the board of trustees.

On December 10, 2025, PwC was replaced by Deloitte & Touch LLP ("D&T") which was appointed as the Series' independent registered public accounting firm for the fiscal year December 31, 2026 audits. The change in the Series' independent registered public accounting firm was approved by the Series' board of trustees, including a majority of the independent trustees, upon recommendation of the audit committee, as part of a broader effort to update board oversight and fund operations. At no point during the Series' fiscal years ended December 31, 2024 and December 31, 2025 and the subsequent interim period through February 11, 2026, were there any disagreements between management and PwC on any matter of accounting principles or practices, financial statement disclosure or auditing scope or procedure.

**Independent legal counsel —** Morgan, Lewis & Bockius LLP, One Federal Street, Boston, MA 02110-1726, serves as independent legal counsel ("counsel") for the Series and for trustees who are not interested persons (as defined by the 1940 Act) of the Series. A determination with respect to the independence of the Series' counsel will be made at least annually by the independent trustees of the Series, as prescribed by applicable 1940 Act rules.

**Prospectuses and reports to shareholders —** The Series' fiscal year ends on December 31. Contract owners are provided updated prospectuses or summary prospectuses by their insurance provider annually and at least semiannually with reports showing the funds' expenses, key statistics, holdings information and investment results (annual report only). The Series' annual financial statements are audited by the independent registered public accounting firm of PwC. The Series' annual financial statements for the fiscal year ended December 31, 2025 were audited by the Series' then-independent registered public accounting firm, PwC. As noted above, D&T will serve as the Series' auditor beginning with the fiscal year ending December 31, 2026.

**Code of ethics —** The Series, Capital Research and Management Company and its affiliated companies have adopted codes of ethics that allow for personal investments, including securities in which the funds of the Series may invest from time to time. These codes include a ban on acquisitions of securities pursuant to an initial public offering; restrictions on acquisitions of private placement securities; pre-clearance and reporting requirements; review of duplicate confirmation statements; annual recertification of compliance with codes of ethics; blackout periods on personal investing for certain investment personnel; a ban on short-term trading profits for investment personnel; limitations on service as a director of publicly traded companies; disclosure of personal securities transactions; and policies regarding political contributions. The subadviser has adopted a code of ethics which restricts, subject to certain conditions, personnel of the subadviser from investing in certain securities.

**Shareholder and trustee responsibility —** Under the laws of certain states, including Massachusetts, where the Series was organized, and California, where the Series' principal office is located, shareholders of a Massachusetts business trust may, under certain circumstances, be held personally liable as partners for the obligations of the Series. However, the risk of a shareholder incurring any financial loss on account of shareholder liability is limited to circumstances in which the Series itself would be unable to meet its obligations. The declaration of trust contains an express disclaimer of shareholder liability for acts or obligations of the Series and provides that notice of the disclaimer may be given in each agreement, obligation, or instrument which is entered into or executed by the Series or trustees. The declaration of trust provides for indemnification out of Series property of any shareholder personally liable for the obligations of the Series and also provides for the Series to reimburse such shareholder for all legal and other expenses reasonably incurred in connection with any such claim or liability.

Under the declaration of trust, the trustees or officers are not liable for actions or failure to act; however, they are not protected from liability by reason of their willful misfeasance, bad faith, gross negligence, or reckless disregard of the duties involved in the conduct of their office. The Series will provide indemnification to its trustees and officers as authorized by its by-laws and by the 1940 Act and the rules and regulations thereunder.

**Registration statement —** A registration statement has been filed with the Securities and Exchange Commission under the Securities Act of 1933 and the 1940 Act with respect to the fund. The prospectus and this statement of additional information do not contain all information set forth in the registration statement, its amendments and exhibits, to which reference is made for further information concerning the fund. Statements contained in the prospectus and this statement of additional information as to the content of the contracts issued through the separate accounts and other legal instruments are summaries. For a complete statement of the terms thereof, reference is made to the registration statements of the separate accounts and contracts as filed with the Securities and Exchange Commission.

**Authorized shares —** The Series was organized as a Massachusetts business trust which permits the fund to issue an unlimited number of shares of beneficial interest of one or more classes.

**Redemption of shares —** While payment of redemptions normally will be in cash, the Series' declaration of trust permits payment of the redemption price wholly or partly with portfolio securities or other fund assets under conditions and circumstances determined by the Series' board of trustees. For example, redemptions could be made in this manner if the board determined that making payments wholly in cash over a particular period would be unfair and/or harmful to other Series shareholders.

**Voting rights —** Shareholders have one vote per share owned. In accordance with current laws, it is anticipated that an insurance company issuing a variable contract that participates in a fund will request voting instructions from variable contract owners and will vote shares or other voting interests

American Funds Insurance Series – Managed Risk Funds — Page 81

------

in the separate account in accordance with voting instructions received, and will vote shares or other voting interests not received in proportion to the voting instructions received by all separate accounts. In addition, fund shares held directly by an insurance company, if any, will be voted in proportion to the voting instructions received by all separate accounts. As a result of proportional voting, the vote of a small number of contract holders could determine the outcome of a shareholder vote.

**Financial statements —** The fund's financial statements, including the investment portfolio and the report of the fund's independent registered public accounting firm contained in the fund's Form N-CSR, are incorporated into the statement of additional information by reference to the fund's Form N-CSR.

**Appendix**

The following descriptions of debt security ratings are based on information provided by Moody's Investors Service, S&P Global Ratings and Fitch Ratings, Inc.

**Description of bond ratings**

**Moody's<br> Long-term rating scale**

**Aaa**<br> Obligations rated Aaa are judged to be of the highest quality, subject to the lowest level of credit risk.

**Aa**<br> Obligations rated Aa are judged to be of high quality and are subject to very low credit risk.

**A**<br> Obligations rated A are considered upper-medium grade and are subject to low credit risk.

**Baa**<br> Obligations rated Baa are judged to be medium-grade and subject to moderate credit risk and as such may possess certain speculative characteristics.

**Ba**<br> Obligations rated Ba are judged to be speculative and are subject to substantial credit risk.

**B**<br> Obligations rated B are considered speculative and are subject to high credit risk.

**Caa**<br> Obligations rated Caa are judged to be speculative and of poor standing and are subject to very high credit risk.

**Ca**<br> Obligations rated Ca are highly speculative and are likely in, or very near, default, with some prospect of recovery of principal and interest.

**C**<br> Obligations rated C are the lowest rated and are typically in default, with little prospect for recovery of principal or interest.

**Note:** Moody's appends numerical modifiers 1, 2, and 3 to each generic rating classification from Aa through Caa. The modifier 1 indicates that the obligation ranks in the higher end of its generic rating category; the modifier 2 indicates a mid-range ranking; and the modifier 3 indicates a ranking in the lower end of that generic rating category. Additionally, a "(hyb)" indicator is appended to all ratings of hybrid securities issued by banks, insurers, finance companies and securities firms.

American Funds Insurance Series – Managed Risk Funds — Page 83

------

**S&P Global Ratings<br> Long-term issue credit ratings**

**AAA**<br> An obligation rated AAA has the highest rating assigned by S&P Global Ratings. The obligor's capacity to meet its financial commitments on the obligation is extremely strong.

**AA**<br> An obligation rated AA differs from the highest-rated obligations only to a small degree. The obligor's capacity to meet its financial commitments on the obligation is very strong.

**A**<br> An obligation rated A is somewhat more susceptible to the adverse effects of changes in circumstances and economic conditions than obligations in higher-rated categories. However, the obligor's capacity to meet its financial commitments on the obligation is still strong.

**BBB**<br> An obligation rated BBB exhibits adequate protection parameters. However, adverse economic conditions or changing circumstances are more likely to weaken the obligor's capacity to meet its financial commitments on the obligation.

**BB, B, CCC, CC, and C**

Obligations rated BB, B, CCC, CC, and C are regarded as having significant speculative characteristics. BB indicates the least degree of speculation and C the highest. While such obligations will likely have some quality and protective characteristics, these may be outweighed by large uncertainties or major exposures to adverse conditions.

**BB**<br> An obligation rated BB is less vulnerable to nonpayment than other speculative issues. However, it faces major ongoing uncertainties or exposure to adverse business, financial, or economic conditions which could lead to the obligor's inadequate capacity to meet its financial commitments on the obligation.

**B**<br> An obligation rated B is more vulnerable to nonpayment than obligations rated BB, but the obligor currently has the capacity to meet its financial commitments on the obligation. Adverse business, financial, or economic conditions will likely impair the obligor's capacity or willingness to meet its financial commitments on the obligation.

**CCC**<br> An obligation rated CCC is currently vulnerable to nonpayment and is dependent upon favorable business, financial, and economic conditions for the obligor to meet its financial commitments on the obligation. In the event of adverse business, financial, or economic conditions, the obligor is not likely to have the capacity to meet its financial commitments on the obligation.

**CC**<br> An obligation rated CC is currently highly vulnerable to nonpayment. The CC rating is used when a default has not occurred, but S&P Global Ratings expects default to be a virtual certainty, regardless of the anticipated time to default.

American Funds Insurance Series – Managed Risk Funds — Page 84

------

**C**<br> An obligation rated C is currently highly vulnerable to nonpayment, and the obligation is expected to have lower relative seniority or lower ultimate recovery compared with obligations that are rated higher.

**D**<br> An obligation rated D is in default or in breach of an imputed promise. For non-hybrid capital instruments, the D rating category is used when payments on an obligation are not made on the date due, unless S&P Global Ratings believes that such payments will be made within the next five business days in the absence of a stated grace period or within the earlier of the stated grace period or the next 30 calendar days. The D rating also will be used upon the filing of a bankruptcy petition or the taking of similar action and where default on an obligation is a virtual certainty, for example due to automatic stay provisions. A rating on an obligation is lowered to D if it is subject to a distressed debt restructuring.

#### Plus (+) or minus (–)
The ratings from AA to CCC may be modified by the addition of a plus or minus sign to show relative standing within the major rating categories.

#### NR
Indicates that a rating has not been assigned or is no longer assigned.

American Funds Insurance Series – Managed Risk Funds — Page 85

------

**Fitch Ratings, Inc.<br> Long-term credit ratings**

**AAA**<br> Highest credit quality. AAA ratings denote the lowest expectation of default risk. They are assigned only in case of exceptionally strong capacity for payment of financial commitments. This capacity is highly unlikely to be adversely affected by foreseeable events.

**AA**<br> Very high credit quality. AA ratings denote expectations of very low default risk. They indicate very strong capacity for payment of financial commitments. This capacity is not significantly vulnerable to foreseeable events.

**A**<br> High credit quality. A ratings denote expectations of low default risk. The capacity for payment of financial commitments is considered strong. This capacity may, nevertheless, be more vulnerable to changes in circumstances or in economic conditions than is the case for higher ratings.

**BBB**<br> Good credit quality. BBB ratings indicate that expectations of default risk are low. The capacity for payment of financial commitments is considered adequate but adverse changes in circumstances and economic conditions are more likely to impair this capacity.

**BB**<br> Speculative. BB ratings indicate an elevated vulnerability to default risk, particularly in the event of adverse changes in business or economic conditions over time; however, business or financial flexibility exists which supports the servicing of financial commitments.

**B**<br> Highly speculative. B ratings indicate that material default risk is present, but a limited margin of safety remains. Financial commitments are currently being met; however, capacity for continued payment is vulnerable to deterioration in the business and economic environment.

**CCC**<br> Substantial credit risk. Default is a real possibility.

**CC**<br> Very high levels of credit risk. Default of some kind appears probable.

**C**<br> Exceptionally high levels of credit risk. Default is imminent or inevitable, or the issuer is in standstill. Conditions that are indicative of a C category rating for an issuer include:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;·The issuer has entered into a grace or cure period following nonpayment of a material financial obligation;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;·The issuer has entered into a temporary negotiated waiver or standstill agreement following a payment default on a material financial obligation; or

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;·Fitch Ratings otherwise believes a condition of RD or D to be imminent or inevitable, including through the formal announcement of a distressed debt exchange.

American Funds Insurance Series – Managed Risk Funds — Page 86

------

**RD**<br> Restricted default. RD ratings indicate an issuer that in Fitch Ratings' opinion has experienced an uncured payment default on a bond, loan or other material financial obligation but which has not entered into bankruptcy filings, administration, receivership, liquidation or other formal winding up procedure, and which has not otherwise ceased operating. This would include:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;·The selective payment default on a specific class or currency of debt;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;·The uncured expiry of any applicable grace period, cure period or default forbearance period following a payment default on a bank loan, capital markets security or other material financial obligation;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;·The extension of multiple waivers or forbearance periods upon a payment default on one or more material financial obligations, either in series or in parallel; or

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;·Execution of a distressed debt exchange on one or more material financial obligations.

**D**<br> Default. D ratings indicate an issuer that in Fitch Ratings' opinion has entered into bankruptcy filings, administration, receivership, liquidation or other formal winding up procedure, or which has otherwise ceased business.

Default ratings are not assigned prospectively to entities or their obligations; within this context, nonpayment on an instrument that contains a deferral feature or grace period will generally not be considered a default until after the expiration of the deferral or grace period, unless a default is otherwise driven by bankruptcy or other similar circumstance, or by a distressed debt exchange.

Imminent default typically refers to the occasion where a payment default has been intimated by the issuer, and is all but inevitable. This may, for example, be where an issuer has missed a scheduled payment, but (as is typical) has a grace period during which it may cure the payment default. Another alternative would be where an issuer has formally announced a distressed debt exchange, but the date of the exchange still lies several days or weeks in the immediate future.

In all cases, the assignment of a default rating reflects the agency's opinion as to the most appropriate rating category consistent with the rest of its universe of ratings, and may differ from the definition of default under the terms of an issuer's financial obligations or local commercial practice.

**Note:** The modifiers "+" or "–" may be appended to a rating to denote relative status within major rating categories. Such suffixes are not added to the AAA long-term rating category, or to categories below B.

**Description of commercial paper ratings**

**Moody's**

**Global short-term rating scale**

#### P-1
Issuers (or supporting institutions) rated Prime-1 have a superior ability to repay short-term debt obligations.

**P-2**

Issuers (or supporting institutions) rated Prime-2 have a strong ability to repay short-term debt obligations.

#### P-3
Issuers (or supporting institutions) rated Prime-3 have an acceptable ability to repay short-term obligations.

**NP**

Issuers (or supporting institutions) rated Not Prime do not fall within any of the Prime rating categories.

#### S&P Global Ratings
**Commercial paper ratings (highest three ratings)**

**A-1**

A short-term obligation rated A-1 is rated in the highest category by S&P Global Ratings. The obligor's capacity to meet its financial commitments on the obligation is strong. Within this category, certain obligations are designated with a plus sign (+). This indicates that the obligor's capacity to meet its financial commitments on these obligations is extremely strong.

**A-2**

A short-term obligation rated A-2 is somewhat more susceptible to the adverse effects of changes in circumstances and economic conditions than obligations in higher rating categories. However, the obligor's capacity to meet its financial commitments on the obligation is satisfactory.

**A-3**

A short-term obligation rated A-3 exhibits adequate protection parameters. However, adverse economic conditions or changing circumstances are more likely to weaken an obligor's capacity to meet its financial commitments on the obligation.

(p) **Code of Ethics** – Code of Ethics for The Capital Group Companies dated May 2025; and
 Code of Ethics for the Registrant – to be provided by amendment

**Item 29.** **Persons Controlled by or Under Common Control with the Fund**

None.

**Item 30.** **Indemnification**

The Registrant is a joint-insured under Investment Adviser/Mutual Fund Errors and Omissions Policies, which insure its officers and trustees against certain liabilities. However, in no event will Registrant maintain insurance to indemnify any such person for any act for which Registrant itself is not permitted to indemnify the individual.

Article V of the Registrant's Declaration of Trust and Article VI of the Registrant's By-Laws as well as the indemnification agreements that the Registrant has entered into with each of its trustees who is not an "interested person" of the Registrant (as defined under the Investment Company Act of 1940, as amended), provide in effect that the Registrant will

indemnify its officers and trustees against any liability or expenses actually and reasonably incurred by such person in any proceeding arising out of or in connection with his or her service to the Registrant, to the fullest extent permitted by applicable law, subject to certain conditions. In accordance with Section 17(h) and 17(i) of the Investment Company Act of 1940, as amended, and their respective terms, these provisions do not protect any person against any liability to the Registrant or its shareholders to which such person would otherwise be subject by reason of willful misfeasance, bad faith, gross negligence, or reckless disregard of the duties involved in the conduct of his or her office.

Insofar as indemnification for liability arising under the Securities Act of 1933 may be permitted to trustees, officers and controlling persons of the Registrant pursuant to the foregoing provisions, or otherwise, the Registrant has been advised that in the opinion of the U.S. Securities and Exchange Commission such indemnification is against public policy as expressed in the Act and is, therefore, unenforceable. In the event that a claim for indemnification against such liabilities (other than the payment by the Registrant of expenses incurred or paid by a trustee, officer or controlling person of the Registrant in the successful defense of any action, suit or proceeding) is asserted by such trustee, officer or controlling person in connection with the securities being registered, the Registrant will, unless in the opinion of its counsel the matter has been settled by controlling precedent, submit to a court of appropriate jurisdiction the question whether such indemnification by it is against public policy as expressed in the Act and will be governed by the final adjudication of such issue.

Registrant will comply with the indemnification requirements contained in the Investment Company Act of 1940, as amended, and Release Nos. 7221 (June 9, 1972) and 11330 (September 4, 1980).

**Item 31.** **Business and Other Connections of the Investment Adviser**

None.

**Item 32.** **Principal Underwriters**

Not applicable.

**Item 33.** **Location of Accounts and Records**

Accounts, books and other records required to be maintained by Rules 31a-1 and 31a-2 under the Investment Company Act of 1940, as amended, are maintained and kept in the offices of the Series and the Registrant's investment adviser, Capital Research and Management Company, 333 South Hope Street, Los Angeles, California 90071. Certain accounting records are maintained and kept in the offices of the investment adviser's accounting department, 6455 Irvine Center Drive, Irvine, California 92618; and/or 5300 Robin Hood Road, Norfolk, Virginia 23513.

Records covering portfolio transactions are also maintained and kept by State Street Bank and Trust Company, One Lincoln Street, Boston, Massachusetts 02111.

Certain other books and records required to be maintained by the Registrant's investment adviser under Section 4.23 under the Commodity Exchange Act and the rules and regulations promulgated thereunder, including records relating to certain portfolio transactions, are maintained and kept in the offices of Bank of New York Mellon, One Wall Street, New York, New York 10286 and/or Milliman Financial Risk Management LLC, 71 South Wacker Drive, 31<sup>st</sup> Floor, Chicago, Illinois 60606.

**Item 34.** **Management Services**

None.

**Item 35.** **Undertakings**

None.

**SIGNATURES**
