<sup>1</sup>The fund does not pay a management fee to the adviser. However, the fund is part of a separately managed account program. Participants in the program pay a "wrap" fee to the sponsor of the program. You should read carefully the wrap-fee brochure provided to you by the sponsor or your investment adviser. The brochure is required to include information about the fees charged to you by the sponsor and the fees paid by the sponsor to Capital Research and Management Company and its affiliates. You pay no additional fees or expenses to purchase shares of the fund.

<sup>2</sup>Based on estimated amounts for the current fiscal year. The investment adviser is currently reimbursing a portion of the other expenses and the fund's transfer agent is currently reimbursing a portion of its fee, which reduces other expenses. The reimbursements will be in effect until March 1, 2026. The adviser or fund's transfer agent 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 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. Although your actual costs may be higher or lower, based on these assumptions your costs would be:

---

| | |
|:---|:---|
| 1 year | 3 years |
| $0 | $0 |

---

**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 and may result in higher taxes when fund shares are held in a taxable account. These costs, which are not reflected in annual fund operating expenses or in the example, affect the fund's investment results. Because the fund has not commenced investment operations as of the date of this prospectus, information regarding the fund's portfolio turnover rate is not shown.

Principal investment strategies The fund invests primarily in bonds and other debt instruments. The fund will normally invest at least 80% of its assets in, or derive at least 80% of its income from, securities that are exempt from regular federal income tax. The fund may substantially invest in securities that may subject you to federal alternative minimum tax. The fund may also invest in debt securities rated BB+ or below and Ba1 or below by Nationally Recognized Statistical Rating Organizations designated by the fund's investment adviser, or unrated but determined by the fund's investment adviser to be of equivalent quality. Securities rated BB+ or below and Ba1 or below are sometimes referred to as "junk bonds." The fund may invest in debt securities of any maturity or duration.

The fund is nondiversified, which allows it to invest a greater percentage of its assets in any one issuer than would otherwise be the case.

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 priced securities 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.For more information regarding the investment process of the fund, see the "Management and organization" section of this prospectus.

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. The fund is intended to be used as part of a managed account program. The performance and objectives of the fund should be evaluated in the context of the investor's managed account program. The fund is not designed to be used as a stand-alone investment.**

*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 municipal securities* — Municipal securities are debt obligations that are exempt from federal, state and/or local income taxes. The yield and/or value of the fund's investments in municipal securities may be adversely affected by events tied to the municipal securities markets, which can be very volatile and significantly impacted by unfavorable legislative or political developments and negative changes in the financial conditions of municipal securities issuers and the economy. To the extent the fund invests in obligations of a municipal issuer, the volatility, credit quality and performance of the fund may be adversely impacted by local political and economic conditions of the issuer. For example, a credit rating downgrade, bond default or bankruptcy involving an issuer within a particular state or territory could affect the market values and marketability of many or all municipal obligations of that state or territory. Income from municipal securities held by the fund could also be declared taxable because of changes in tax laws or interpretations by taxing authorities or as a result of noncompliant conduct of a municipal issuer. Additionally, the relative amount of publicly available information about municipal securities is generally less than that for corporate securities.

*Alternative minimum tax —* The fund may invest in securities that may subject you to federal alternative minimum tax. Therefore, while the fund's distributions from tax-exempt securities are not subject to regular federal income tax, a portion or all of the distributions may be included in determining a shareholder's federal alternative minimum tax.

------

*Investing in debt instruments* — The prices of, and the income generated by, bonds and other debt securities held by the 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 the 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.

*Tax-exempt securities* — While the fund seeks to purchase securities which bear interest that is exempt from federal income taxes there are risks that such interest may be reclassified as taxable by the Internal Revenue Service, or a state tax authority. Actions by the issuer or future legislative, administrative or court actions also could adversely affect the tax-exempt status of interest paid by such securities. Such reclassifications or actions could cause interest from a security to become includable in the gross income of the holder of the security, possibly retroactively, subjecting fund shareholders to increased tax liability. In addition, such reclassifications or actions could cause the value of a security, and therefore the value of the fund's shares, to decline.

*Investing in lower rated debt instruments* — Lower rated bonds and other lower rated debt securities, rated Ba1/BB+ or below by Nationally Recognized Statistical Rating Organizations, generally have higher rates of interest and involve greater risk of default or price declines due to changes in the issuer's creditworthiness than those of higher quality debt securities. The market prices of these securities may fluctuate more than the prices of higher quality debt securities and may decline significantly in periods of general economic difficulty. These risks may be increased with respect to investments in junk bonds.

*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.

*Credit and liquidity support* — Changes in the credit quality of banks and financial institutions providing credit and liquidity support features with respect to securities held by the fund could cause the values of these securities to decline.

*Investing in similar municipal bonds* — Investing significantly in municipal obligations of multiple issuers in the same state or backed by revenues of similar types of projects or industries may make the fund more susceptible to certain economic, political or regulatory occurrences. As a result, the fund has greater risk of volatility, and greater risk of loss, from these investments.

*Interest rate risk* — The values and liquidity of the securities held by the 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. The fund may invest in variable and floating rate securities. 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. 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, the 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.

*Nondiversification* — As a nondiversified fund, the fund may invest a greater percentage of its assets in fewer issuers than a diversified fund. A fund that invests in a relatively smaller number of issuers is more susceptible to risks associated with a single economic, political, geographic or regulatory occurrence than a diversified fund might be. In addition, poor performance by a single issuer could adversely affect fund performance more than if the fund were invested in a larger number of issuers. The value of the fund's shares can be expected to fluctuate more than might be the case if the fund were more broadly diversified.

*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.

Purchase and sale of fund shares Shares of the fund are available for purchase only by or on behalf of separately managed account clients where the fund's adviser or an affiliate of the adviser (each a "Managed Account Adviser") has an agreement with the managed account program sponsor (the "Program Sponsor"), or directly with the client, to provide management or advisory services to the managed account or to the Program Sponsor for its use in managing such account. Shares of the fund are not generally available to the public.

There are no maximum or minimum investment requirements in the fund, although your Program Sponsor may have certain investment requirements.

Purchase and sale (redemption) orders are processed at the net asset value next calculated after the transfer agent receives the order from the account each day the New York Stock Exchange is open. Orders in good order received after the New York Stock Exchange closes (scheduled or unscheduled) will be processed at the net asset value calculated on the following business day.

The fund reserves the right to redeem shares held by or on behalf of any shareholder who ceases to be an eligible investor as described above and, each shareholder, by purchasing shares of the fund, agrees to any such redemption. If such shareholder fails to meet a fund's eligibility criteria, the fund may, in its sole discretion, redeem, or work with a financial intermediary as necessary to cause the redemption of all of the shares of such shareholder. The liquidation of such shares may have tax consequences for the investor, including the investor potentially incurring tax liability if such liquidation results in a gain. Investors should carefully consider the potential impact of such liquidations and restrictions before selecting a managed account strategy that contemplates investment in a fund. Please contact your Program Sponsor for further information.

Tax information Dividends and capital gain distributions you receive from the fund are subject to federal income taxes and may also be subject to state and local taxes, unless you are tax-exempt or your account is tax-favored (in which case you may be taxed later, upon withdrawal of your investment from such account).
