<sup>1</sup> *&nbsp;&nbsp;&nbsp;&nbsp;Purchases of $1 million or more may be subject to a contingent deferred sales charge of 1.00% if the shares are redeemed within one year of the date of the purchase.*

<sup>2</sup>*&nbsp;&nbsp;&nbsp;&nbsp;The management fee has been restated to reflect current fees.*

<sup>3</sup>*&nbsp;&nbsp;&nbsp;&nbsp;The advisor has agreed to waive a portion of the fund's management fee. The advisor expects this waiver to continue until November 30, 2026 and cannot terminate it prior to such date without the approval of the Board of Directors.*

**Example**

The example below is intended to help you compare the costs of investing in the fund with the costs 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 all of your shares at the end of those periods, and that you earn a 5% return each year. The example also assumes that the fund's operating expenses remain the same except that it reflects the rate and duration of any fee waivers noted in the table above. 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* |
| Investor Class | $78 | $252 | $441 | $986 |

| A Class | $672 | $887 | $1118 | $1780 |

| R Class | $129 | $409 | $710 | $1564 |
| R6 Class | $42 | $154 | $276 | $631 |

**Portfolio Turnover**

Because the fund buys and sells shares of other American Century mutual funds (the underlying funds) directly from the issuers, the fund is not expected to incur transaction costs directly. However, as a shareholder in the underlying funds, the fund indirectly pays transaction costs, such as commissions, when the underlying funds buy and sell securities (or "turn over" their portfolios). 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 performance. During the most recent fiscal year, the fund's portfolio turnover rate was [14%] of the average value of its portfolio.

**Principal Investment Strategies**

One Choice In Retirement Portfolio is a "fund of funds," meaning that it seeks to achieve its objective by investing in other American Century mutual funds (the underlying funds) that represent a variety of asset classes and investment styles. The underlying stock funds draw on growth, value and quantitative investment techniques and diversify investments among small, medium and large U.S. and foreign companies. The underlying bond funds invest in fixed-income securities that vary by issuer type (corporate and government), credit quality (investment-grade and high-yield or "junk bonds") and geographic exposure (domestic and international). Short-term investments include underlying funds that invest in fixed-income or debt instruments and have a shorter-term weighted average duration, typically three years or less. The following table indicates the fund's neutral mix; that is, how the fund's investments generally will be allocated among the major asset classes as of the date of this prospectus.

---

| | | |
|:---|:---|:---|
| **Equity Securities (Stock Funds)** |  | &nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;**45.0%** |
| &nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;*U.S. Equity* | &nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;*33.0 %* |  |
| &nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;*International Equity* | &nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;*11.0 %* |  |
| &nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;*Real Estate* | &nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;*1.0 %* |  |
| **Fixed-Income Securities (Bond Funds)** |  | &nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;**47.3%** |
| **Short-Term Investments (Short-Term Funds)** |  | &nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;**7.7%** |

---

The neutral mix of One Choice In Retirement Portfolio is expected to remain fixed over time. The fund is generally intended for investors near to, at, or in retirement and who likely are no longer making new investments in the fund. The fund is designed for investors who plan to gradually withdraw the value of their account after retirement. The fund assumes a retirement age of 65 and may not be appropriate for an investor retiring at an age well before or after age 65.

The portfolio managers regularly review the fund's allocations to determine whether rebalancing is appropriate. In order to better balance risks in changing market environments, the portfolio managers may make modest deviations from the neutral mix in light of prevailing market conditions. We reserve the right to modify the neutral mix and underlying funds from time to time should circumstances warrant a change.

**Principal Risks**

• **Allocation Risk** – The fund's performance and risks depend in part on the managers' skill in determining the fund's neutral mix, selecting and weighting the underlying funds, and implementing any deviations from the neutral mix. The managers' evaluations and assumptions regarding asset classes or underlying funds may differ from actual market conditions.

• **Fund of Funds Risks** – The fund's performance and risks reflect the performance and risks of the underlying American Century Investments funds in which it invests. The fund's investment in other American Century Investments funds may create a conflict of interest for the fund's advisor.

• **"Growth" and "Value" Style Risks** – The underlying funds represent a mix of investment styles, each of which has risks associated with it. Growth stocks can be volatile and may lack dividends that can cushion share prices during market declines. Value stocks may continue to be undervalued by the market for long periods of time.

• **Small- and Mid-Cap Stock Risks** – Stocks of smaller companies may be more volatile than larger-company stocks. Smaller companies may have limited financial resources, product lines and markets, and their securities may trade less frequently and in more limited volumes than the securities of larger companies, which could lead to higher transaction costs. To the extent an underlying fund invests in these companies, it may take on more risk.

• **Interest Rate Risk** – Generally, when interest rates rise, the value of an underlying fund's fixed-income securities will decline. The opposite is true when interest rates decline. Underlying funds with longer weighted average maturities are more sensitive to interest rate changes. A period of rising interest rates may negatively affect the performance of underlying fixed-income funds.

• **Credit Risk** – The value of an underlying fund's fixed-income securities will be affected adversely by any erosion in the ability of the issuers of these securities to make interest and principal payments as they become due. Changes in the credit rating of a fixed-income security held by an underlying fund could have a similar effect.

------

• **Foreign Securities Risk** – Some of the underlying funds invest in foreign securities, which are generally riskier than U.S. securities. Political events, social and economic events, natural disasters and public health emergencies occurring in a country where the fund invests could cause the fund's investments in that country to experience gains or losses. Securities of foreign issuers may be less liquid, more volatile and harder to value than U.S. securities. Fluctuations in currency exchange rates also may affect an underlying fund's share price.

• **High-Yield Securities Risk** – Some of the underlying funds may invest in high-yield securities, which are considered to have speculative characteristics and are more likely to be negatively affected by changes in economic conditions.

**• Market Risk** – The value of the fund's shares will go up and down based on the performance of the underlying funds in which it invests. The value of the underlying funds' shares will, in turn, fluctuate based on the performance of the securities they own and other factors generally affecting the securities market. Market risks, including political, regulatory, economic and social developments, can affect the value of the fund's investments. Natural disasters, public health emergencies, war, terrorism and other unforeseeable events may lead to increased market volatility and may have adverse long-term effects on world economies and markets generally.

• **Principal Loss Risk** – At any given time your shares may be worth less than the price you paid for them. In other words, it is possible to lose money by investing in the fund, including losses near to, at, or after retirement. There is no guarantee that the fund will provide adequate income at or through your retirement.

An investment in the fund is not a bank deposit, and it is not insured or guaranteed by the Federal Deposit Insurance Corporation (FDIC) or any other government agency.

**Fund Performance**

The following bar chart and table provide some indication of the risks of investing in the fund. The bar chart shows changes in the fund's performance from year to year for Investor Class shares. The table shows how the fund's average annual returns for the periods shown compared with those of broad measures of market performance. The table also shows returns for the S&P Target Date Retirement Income Index, which the advisor considers to be more representative of the fund's investment strategy. The fund's past performance (before and after taxes) is not necessarily an indication of how the fund will perform in the future. For current performance information, including yields, please visit americancentury.com.

Sales charges and account fees, if applicable, are not reflected in the bar chart. If those charges were included, returns would be less than those shown.

financial intermediaries may require their clients to meet different investment minimums. The minimum may be waived for broker-dealer sponsored wrap program accounts, fee based accounts, and accounts through bank/trust and wealth management advisory organizations.

The minimum initial investment amount for I Class is generally $5 million ($3 million for endowments and foundations), but the minimum may be waived if you have an aggregate investment in the American Century family of funds of $10 million or more ($5 million for endowments and foundations). This includes accounts held directly with American Century and those held through a financial intermediary.

There is no minimum initial investment amount for R6 Class shares.

For all share classes, there is no minimum initial investment amount for certain employer-sponsored retirement plans, however, financial intermediaries or plan recordkeepers may require plans to meet different minimums.

**Tax Information**

Fund distributions are generally taxable as ordinary income or capital gains, unless you are investing through a tax-deferred account such as a 401(k) or individual retirement account (in which case you may be taxed upon withdrawal of your investment from such account).

**Payments to Broker-Dealers and Other Financial Intermediaries**

If you purchase the fund through a broker-dealer or other financial intermediary (such as a bank, insurance company, plan sponsor or financial professional), the fund and its related companies may pay the intermediary for the sale of fund shares and related services for investments in all classes except the R6 Class. These payments may create a conflict of interest by influencing the broker-dealer or other intermediary and your salesperson to recommend the fund over another investment. Ask your salesperson or visit your financial intermediary's website for more information.

**Example**

The example below is intended to help you compare the costs of investing in the fund with the costs 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 all of your shares at the end of those periods, and that you earn a 5% return each year. The example also assumes that the fund's operating expenses remain the same except that it reflects the rate and duration of any fee waivers noted in the table above. Although your actual costs may be higher or lower, based on these assumptions your costs would be:

**Portfolio Turnover** 

Because the fund buys and sells shares of other American Century mutual funds (the underlying funds) directly from the issuers, the fund is not expected to incur transaction costs directly. However, as a shareholder in the underlying funds, the fund indirectly pays transaction costs, such as commissions, when the underlying funds buy and sell securities (or "turn over" their portfolios). 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 performance. During the most recent fiscal year, the fund's portfolio turnover rate was [15%] of the average value of its portfolio.

**Principal Investment Strategies**

One Choice 2030 Portfolio is a "fund of funds," meaning that it seeks to achieve its objective by investing in other American Century mutual funds (the underlying funds) that represent a variety of asset classes and investment styles. The underlying stock funds draw on growth, value and quantitative investment techniques and diversify investments among small, medium and large U.S. and foreign companies. The underlying bond funds invest in fixed-income securities that vary by issuer type (corporate and government), credit quality (investment-grade and high-yield or "junk bonds") and geographic exposure (domestic and international). Short-term investments include underlying funds that invest in fixed-income or debt instruments and have a shorter-term weighted average duration, typically three years or less. The following table indicates the fund's neutral mix; that is, how the fund's investments generally will be allocated among the major asset classes as of the date of this prospectus.

| | | |
|:---|:---|:---|
| **Equity Securities (Stock Funds)** |  | &nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;**50.0%** |
| &nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;*U.S. Equity* | &nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;*36.0 %* |  |

The target date in the fund name (2030) refers to the approximate year an investor plans to retire and likely would stop making new investments in the fund. The fund assumes a retirement age of 65 and may not be appropriate for an investor who plans to retire at or near the target date, but at an age well before or after 65. As the target date approaches, the fund's neutral mix will become more conservative by decreasing the allocation to stocks and increasing the allocation to bonds and short-term investments. By the time the fund reaches its target date, the neutral mix will become fixed and match that of One Choice In Retirement Portfolio, which is currently 45% stock funds, 47.3% bond funds and 7.7% short-term funds. The fund is designed for investors who plan to withdraw the value of their account gradually after retirement. The following chart shows how the neutral mix is expected to change over time according to a predetermined glide path.

![glidepatha.jpg](glidepatha.jpg)

------

The portfolio managers regularly review the fund's allocations to determine whether rebalancing is appropriate. In order to better balance risks in changing market environments, the portfolio managers may make modest deviations from the neutral mix in light of prevailing market conditions. We reserve the right to modify the neutral mix and underlying funds from time to time should circumstances warrant a change.

**Principal Risks**

• **Allocation Risk** – The fund's performance and risks depend in part on the managers' skill in determining the fund's neutral mix, selecting and weighting the underlying funds, and implementing any deviations from the neutral mix. The managers' evaluations and assumptions regarding asset classes or underlying funds may differ from actual market conditions.

• **Fund of Funds Risks** – The fund's performance and risks reflect the performance and risks of the underlying American Century Investments funds in which it invests. The fund's investment in other American Century Investments funds may create a conflict of interest for the fund's advisor.

• **"Growth" and "Value" Style Risks** – The underlying funds represent a mix of investment styles, each of which has risks associated with it. Growth stocks can be volatile and may lack dividends that can cushion share prices during market declines. Value stocks may continue to be undervalued by the market for long periods of time.

• **Small- and Mid-Cap Stock Risks** – Stocks of smaller companies may be more volatile than larger-company stocks. Smaller companies may have limited financial resources, product lines and markets, and their securities may trade less frequently and in more limited volumes than the securities of larger companies, which could lead to higher transaction costs. To the extent an underlying fund invests in these companies, it may take on more risk.

• **Interest Rate Risk** – Generally, when interest rates rise, the value of an underlying fund's fixed-income securities will decline. The opposite is true when interest rates decline. Underlying funds with longer weighted average maturities are more sensitive to interest rate changes. A period of rising interest rates may negatively affect the performance of underlying fixed-income funds.

• **Credit Risk** – The value of an underlying fund's fixed-income securities will be affected adversely by any erosion in the ability of the issuers of these securities to make interest and principal payments as they become due. Changes in the credit rating of a fixed-income security held by an underlying fund could have a similar effect.

• **Foreign Securities Risk** – Some of the underlying funds invest in foreign securities, which are generally riskier than U.S. securities. Political events, social and economic events, natural disasters and public health emergencies occurring in a country where the fund invests could cause the fund's investments in that country to experience gains or losses. Securities of foreign issuers may be less liquid, more volatile and harder to value than U.S. securities. Fluctuations in currency exchange rates also may affect an underlying fund's share price. Investing in securities of companies located in emerging market countries is generally riskier than investing in securities of companies located in developed foreign countries.

• **High-Yield Securities Risk** – Some of the underlying funds may invest in high-yield securities, which are considered to have speculative characteristics and are more likely to be negatively affected by changes in economic conditions.

**• Market Risk** – The value of the fund's shares will go up and down based on the performance of the underlying funds in which it invests. The value of the underlying funds' shares will, in turn, fluctuate based on the performance of the securities they own and other factors generally affecting the securities market. Market risks, including political, regulatory, economic and social developments, can affect the value of the fund's investments. Natural disasters, public health emergencies, war, terrorism and other unforeseeable events may lead to increased market volatility and may have adverse long-term effects on world economies and markets generally.

• **Principal Loss Risk** – At any given time your shares may be worth less than the price you paid for them. In other words, it is possible to lose money by investing in the fund, including losses near to, at, or after retirement. There is no guarantee that the fund will provide adequate income at or through your retirement.

An investment in the fund is not a bank deposit, and it is not insured or guaranteed by the Federal Deposit Insurance Corporation (FDIC) or any other government agency.

**Fund Performance**

The following bar chart and table provide some indication of the risks of investing in the fund. The bar chart shows changes in the fund's performance from year to year for Investor Class shares. The table shows how the fund's average annual returns for the periods shown compared with those of broad measures of market performance. The table also shows returns for the S&P Target Date to 2030 Index, which the advisor considers to be more representative of the fund's investment strategy. The fund's past performance (before and after taxes) is not necessarily an indication of how the fund will perform in the future. For current performance information, including yields, please visit americancentury.com.

Sales charges and account fees, if applicable, are not reflected in the bar chart. If those charges were included, returns would be less than those shown.

**Portfolio Turnover** 

Because the fund buys and sells shares of other American Century mutual funds (the underlying funds) directly from the issuers, the fund is not expected to incur transaction costs directly. However, as a shareholder in the underlying funds, the fund indirectly pays transaction costs, such as commissions, when the underlying funds buy and sell securities (or "turn over" their portfolios). 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 performance. During the most recent fiscal year, the fund's portfolio turnover rate was [15%] of the average value of its portfolio.

**Principal Investment Strategies**

One Choice 2035 Portfolio is a "fund of funds," meaning that it seeks to achieve its objective by investing in other American Century mutual funds (the underlying funds) that represent a variety of asset classes and investment styles. The underlying stock funds draw on growth, value and quantitative investment techniques and diversify investments among small, medium and large U.S. and foreign companies. The underlying bond funds invest in fixed-income securities that vary by issuer type (corporate and government), credit quality (investment-grade and high-yield or "junk bonds") and geographic exposure (domestic and international). Short-term investments include underlying funds that invest in fixed-income or debt instruments and have a shorter-term weighted average duration, typically three years or less. The following table indicates the fund's neutral mix; that is, how the fund's investments generally will be allocated among the major asset classes as of the date of this prospectus.

The target date in the fund name (2035) refers to the approximate year an investor plans to retire and likely would stop making new investments in the fund. The fund assumes a retirement age of 65 and may not be appropriate for an investor who plans to retire at or near the target date, but at an age well before or after 65. As the target date approaches, the fund's neutral mix will become more conservative by decreasing the allocation to stocks and increasing the allocation to bonds and short-term investments. By the time the fund reaches its target date, the neutral mix will become fixed and match that of One Choice In Retirement Portfolio, which is currently 45% stock funds, 47.3% bond funds and 7.7% short-term funds. The fund is designed for investors who plan to withdraw the value of their account gradually after retirement. The following chart shows how the neutral mix is expected to change over time according to a predetermined glide path.

------

The portfolio managers regularly review the fund's allocations to determine whether rebalancing is appropriate. In order to better balance risks in changing market environments, the portfolio managers may make modest deviations from the neutral mix in light of prevailing market conditions. We reserve the right to modify the neutral mix and underlying funds from time to time should circumstances warrant a change.

**Principal Risks**

• **Allocation Risk** – The fund's performance and risks depend in part on the managers' skill in determining the fund's neutral mix, selecting and weighting the underlying funds, and implementing any deviations from the neutral mix. The managers' evaluations and assumptions regarding asset classes or underlying funds may differ from actual market conditions.

• **Fund of Funds Risks** – The fund's performance and risks reflect the performance and risks of the underlying American Century Investments funds in which it invests. The fund's investment in other American Century Investments funds may create a conflict of interest for the fund's advisor.

• **"Growth" and "Value" Style Risks** – The underlying funds represent a mix of investment styles, each of which has risks associated with it. Growth stocks can be volatile and may lack dividends that can cushion share prices during market declines. Value stocks may continue to be undervalued by the market for long periods of time.

• **Small- and Mid-Cap Stock Risks** – Stocks of smaller companies may be more volatile than larger-company stocks. Smaller companies may have limited financial resources, product lines and markets, and their securities may trade less frequently and in more limited volumes than the securities of larger companies, which could lead to higher transaction costs. To the extent an underlying fund invests in these companies, it may take on more risk.

• **Interest Rate Risk** – Generally, when interest rates rise, the value of an underlying fund's fixed-income securities will decline. The opposite is true when interest rates decline. Underlying funds with longer weighted average maturities are more sensitive to interest rate changes. A period of rising interest rates may negatively affect the performance of underlying fixed-income funds.

• **Credit Risk** – The value of an underlying fund's fixed-income securities will be affected adversely by any erosion in the ability of the issuers of these securities to make interest and principal payments as they become due. Changes in the credit rating of a fixed-income security held by an underlying fund could have a similar effect.

• **Foreign Securities Risk** – Some of the underlying funds invest in foreign securities, which are generally riskier than U.S. securities. Political events, social and economic events, natural disasters and public health emergencies occurring in a country where the fund invests could cause the fund's investments in that country to experience gains or losses. Securities of foreign issuers may be less liquid, more volatile and harder to value than U.S. securities. Fluctuations in currency exchange rates also may affect an underlying fund's share price.

• **Emerging Market Risk** - Investing in securities of companies located in emerging market countries generally is also riskier than investing in securities of companies located in foreign developed countries. Emerging market countries may have unstable governments and/or economies that are subject to sudden change. These changes may be magnified by the countries' emergent financial markets, resulting in significant volatility to investments in these countries

• **Real Estate Investing Risk** - An investment in the fund may be subject to many of the same risks as a direct investment in real estate. These risks include changes in economic conditions, interest rates, property values, property tax increases, overbuilding and increased competition, environmental contamination, zoning and natural disasters. This is due to the fact that the value of the fund's investments may be affected by the value of the real estate owned by the companies in which it invests.

**• Market Risk** – The value of the fund's shares will go up and down based on the performance of the underlying funds in which it invests. The value of the underlying funds' shares will, in turn, fluctuate based on the performance of the securities they own and other factors generally affecting the securities market. Market risks, including political, regulatory, economic and social developments, can affect the value of the fund's investments. Natural disasters, public health emergencies, war, terrorism and other unforeseeable events may lead to increased market volatility and may have adverse long-term effects on world economies and markets generally.

• **Principal Loss Risk** – At any given time your shares may be worth less than the price you paid for them. In other words, it is possible to lose money by investing in the fund, including losses near to, at, or after retirement. There is no guarantee that the fund will provide adequate income at or through your retirement.

An investment in the fund is not a bank deposit, and it is not insured or guaranteed by the Federal Deposit Insurance Corporation (FDIC) or any other government agency.

**Fund Performance**

The following bar chart and table provide some indication of the risks of investing in the fund. The bar chart shows changes in the fund's performance from year to year for Investor Class shares. The table shows how the fund's average annual returns for the periods shown compared with those of broad measures of market performance. The table also shows returns for the S&P Target Date to 2035 Index, which the advisor considers to be more representative of the fund's investment strategy. The fund's past performance (before

If you purchase the fund through a broker-dealer or other financial intermediary (such as a bank, insurance company, plan sponsor or financial professional), the fund and its related companies may pay the intermediary for the sale of fund shares and related services in all classes except the R6 Class.

<sup>3</sup>*&nbsp;&nbsp;&nbsp;&nbsp;The advisor has agreed to waive a portion of the fund's management fee. The advisor expects this waiver to continue until November 30, 2026 and cannot terminate it prior to such date without the approval of the Board of Directors.*

**Example**

The example below is intended to help you compare the costs of investing in the fund with the costs 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 all of your shares at the end of those periods, and that you earn a 5% return each year. The example also assumes that the fund's operating expenses remain the same except that it reflects the rate and duration of any fee waivers noted in the table above. Although your actual costs may be higher or lower, based on these assumptions your costs would be:

**Portfolio Turnover**

Because the fund buys and sells shares of other American Century mutual funds (the underlying funds) directly from the issuers, the fund is not expected to incur transaction costs directly. However, as a shareholder in the underlying funds, the fund indirectly pays transaction costs, such as commissions, when the underlying funds buy and sell securities (or "turn over" their portfolios). 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 performance. During the most recent fiscal year, the fund's portfolio turnover rate was [14%] of the average value of its portfolio.

The portfolio managers regularly review the fund's allocations to determine whether rebalancing is appropriate. In order to better balance risks in changing market environments, the portfolio managers may make modest deviations from the neutral mix in light of prevailing market conditions. We reserve the right to modify the neutral mix and underlying funds from time to time should circumstances warrant a change.

**Principal Risks**

• **Allocation Risk** – The fund's performance and risks depend in part on the managers' skill in determining the fund's neutral mix, selecting and weighting the underlying funds, and implementing any deviations from the neutral mix. The managers' evaluations and assumptions regarding asset classes or underlying funds may differ from actual market conditions.

• **Fund of Funds Risks** – The fund's performance and risks reflect the performance and risks of the underlying American Century Investments funds in which it invests. The fund's investment in other American Century Investments funds may create a conflict of interest for the fund's advisor.

• **"Growth" and "Value" Style Risks** – The underlying funds represent a mix of investment styles, each of which has risks associated with it. Growth stocks can be volatile and may lack dividends that can cushion share prices during market declines. Value stocks may continue to be undervalued by the market for long periods of time.

• **Small- and Mid-Cap Stock Risks** – Stocks of smaller companies may be more volatile than larger-company stocks. Smaller companies may have limited financial resources, product lines and markets, and their securities may trade less frequently and in more limited volumes than the securities of larger companies, which could lead to higher transaction costs. To the extent an underlying fund invests in these companies, it may take on more risk.

• **Interest Rate Risk** – Generally, when interest rates rise, the value of an underlying fund's fixed-income securities will decline. The opposite is true when interest rates decline. Underlying funds with longer weighted average maturities are more sensitive to interest rate changes. A period of rising interest rates may negatively affect the performance of underlying fixed-income funds.

• **Credit Risk** – The value of an underlying fund's fixed-income securities will be affected adversely by any erosion in the ability of the issuers of these securities to make interest and principal payments as they become due. Changes in the credit rating of a fixed-income security held by an underlying fund could have a similar effect.

• **Foreign Securities Risk** – Some of the underlying funds invest in foreign securities, which are generally riskier than U.S. securities. Political events, social and economic events, natural disasters and public health emergencies occurring in a country where the fund invests could cause the fund's investments in that country to experience gains or losses. Securities of foreign issuers may be less liquid, more volatile and harder to value than U.S. securities. Fluctuations in currency exchange rates also may affect an underlying fund's share price.

• **Emerging Market Risk** - Investing in securities of companies located in emerging market countries generally is also riskier than investing in securities of companies located in foreign developed countries. Emerging market countries may have unstable governments and/or economies that are subject to sudden change. These changes may be magnified by the countries' emergent financial markets, resulting in significant volatility to investments in these countries.

• **Real Estate Investing Risk** - An investment in the fund may be subject to many of the same risks as a direct investment in real estate. These risks include changes in economic conditions, interest rates, property values, property tax increases, overbuilding and increased competition, environmental contamination, zoning and natural disasters. This is due to the fact that the value of the fund's investments may be affected by the value of the real estate owned by the companies in which it invests.

Market risks, including political, regulatory, economic and social developments, can affect the value of the fund's investments.

<sup>2</sup>*&nbsp;&nbsp;&nbsp;&nbsp;The management fee has been restated to reflect current fees.*

<sup>3</sup>*&nbsp;&nbsp;&nbsp;&nbsp;The advisor has agreed to waive a portion of the fund's management fee. The advisor expects this waiver to continue until November 30, 2026 and cannot terminate it prior to such date without the approval of the Board of Directors.*

**Example**

The example below is intended to help you compare the costs of investing in the fund with the costs 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 all of your shares at the end of those periods, and that you earn a 5% return each year. The example also assumes that the fund's operating expenses remain the same except that it reflects the rate and duration of any fee waivers noted in the table above. Although your actual costs may be higher or lower, based on these assumptions your costs would be:

**Portfolio Turnover** 

Because the fund buys and sells shares of other American Century mutual funds (the underlying funds) directly from the issuers, the fund is not expected to incur transaction costs directly. However, as a shareholder in the underlying funds, the fund indirectly pays transaction costs, such as commissions, when the underlying funds buy and sell securities (or "turn over" their portfolios). 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 performance. During the most recent fiscal year, the fund's portfolio turnover rate was [13%] of the average value of its portfolio.

**Principal Investment Strategies**

One Choice 2045 Portfolio is a "fund of funds," meaning that it seeks to achieve its objective by investing in other American Century mutual funds (the underlying funds) that represent a variety of asset classes and investment styles. The underlying stock funds draw on growth, value and quantitative investment techniques and diversify investments among small, medium and large U.S. and foreign companies. The underlying bond funds invest in fixed-income securities that vary by issuer type (corporate and government), credit quality (investment-grade and high-yield or "junk bonds") and geographic exposure (domestic and international). Short-term investments include underlying funds that invest in fixed-income or debt instruments and have a shorter-term weighted average duration, typically three years or less. The following table indicates the fund's neutral mix; that is, how the fund's investments generally will be allocated among the major asset classes as of the date of this prospectus.

| | | |
|:---|:---|:---|
| **Equity Securities (Stock Funds)** |  | &nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;**67.5%** |

The target date in the fund name (2045) refers to the approximate year an investor plans to retire and likely would stop making new investments in the fund. The fund assumes a retirement age of 65 and may not be appropriate for an investor who plans to retire at or near the target date, but at an age well before or after 65. As the target date approaches, the fund's neutral mix will become more conservative by decreasing the allocation to stocks and increasing the allocation to bonds and short-term investments. By the time the fund reaches its target date, the neutral mix will become fixed and match that of One Choice In Retirement Portfolio, which is currently 45% stock funds, 47.3% bond funds and 7.7% short-term funds. The fund is designed for investors who plan to withdraw the value of their account gradually after retirement. The following chart shows how the neutral mix is expected to change over time according to a predetermined glide path.

![glidepatha.jpg](glidepatha.jpg)

------

The portfolio managers regularly review the fund's allocations to determine whether rebalancing is appropriate. In order to better balance risks in changing market environments, the portfolio managers may make modest deviations from the neutral mix in light of prevailing market conditions. We reserve the right to modify the neutral mix and underlying funds from time to time should circumstances warrant a change.

**Principal Risks**

• **Allocation Risk** – The fund's performance and risks depend in part on the managers' skill in determining the fund's neutral mix, selecting and weighting the underlying funds, and implementing any deviations from the neutral mix. The managers' evaluations and assumptions regarding asset classes or underlying funds may differ from actual market conditions.

• **Fund of Funds Risks** – The fund's performance and risks reflect the performance and risks of the underlying American Century Investments funds in which it invests. The fund's investment in other American Century Investments funds may create a conflict of interest for the fund's advisor.

• **"Growth" and "Value" Style Risks** – The underlying funds represent a mix of investment styles, each of which has risks associated with it. Growth stocks can be volatile and may lack dividends that can cushion share prices during market declines. Value stocks may continue to be undervalued by the market for long periods of time.

• **Small- and Mid-Cap Stock Risks** – Stocks of smaller companies may be more volatile than larger-company stocks. Smaller companies may have limited financial resources, product lines and markets, and their securities may trade less frequently and in more limited volumes than the securities of larger companies, which could lead to higher transaction costs. To the extent an underlying fund invests in these companies, it may take on more risk.

• **Interest Rate Risk** – Generally, when interest rates rise, the value of an underlying fund's fixed-income securities will decline. The opposite is true when interest rates decline. Underlying funds with longer weighted average maturities are more sensitive to interest rate changes. A period of rising interest rates may negatively affect the performance of underlying fixed-income funds.

• **Credit Risk** – The value of an underlying fund's fixed-income securities will be affected adversely by any erosion in the ability of the issuers of these securities to make interest and principal payments as they become due. Changes in the credit rating of a fixed-income security held by an underlying fund could have a similar effect.

• **Foreign Securities Risk** – Some of the underlying funds invest in foreign securities, which are generally riskier than U.S. securities. Political events, social and economic events, natural disasters and public health emergencies occurring in a country where the fund invests could cause the fund's investments in that country to experience gains or losses. Securities of foreign issuers may be less liquid, more volatile and harder to value than U.S. securities. Fluctuations in currency exchange rates also may affect an underlying fund's share price.

• **Emerging Market Risk** - Investing in securities of companies located in emerging market countries generally is also riskier than investing in securities of companies located in foreign developed countries. Emerging market countries may have unstable governments and/or economies that are subject to sudden change. These changes may be magnified by the countries' emergent financial markets, resulting in significant volatility to investments in these countries.

• **Real Estate Investing Risk** - An investment in the fund may be subject to many of the same risks as a direct investment in real estate. These risks include changes in economic conditions, interest rates, property values, property tax increases, overbuilding and increased competition, environmental contamination, zoning and natural disasters. This is due to the fact that the value of the fund's investments may be affected by the value of the real estate owned by the companies in which it invests.

**• Market Risk** – The value of the fund's shares will go up and down based on the performance of the underlying funds in which it invests. The value of the underlying funds' shares will, in turn, fluctuate based on the performance of the securities they own and other factors generally affecting the securities market. Market risks, including political, regulatory, economic and social developments, can affect the value of the fund's investments. Natural disasters, public health emergencies, war, terrorism and other unforeseeable events may lead to increased market volatility and may have adverse long-term effects on world economies and markets generally.

• **Principal Loss Risk** – At any given time your shares may be worth less than the price you paid for them. In other words, it is possible to lose money by investing in the fund, including losses near to, at, or after retirement. There is no guarantee that the fund will provide adequate income at or through your retirement.

An investment in the fund is not a bank deposit, and it is not insured or guaranteed by the Federal Deposit Insurance Corporation (FDIC) or any other government agency.

**Fund Performance**

The following bar chart and table provide some indication of the risks of investing in the fund. The bar chart shows changes in the fund's performance from year to year for Investor Class shares. The table shows how the fund's average annual returns for the periods shown compared with those of broad measures of market performance. The table also shows returns for the S&P Target Date to 2045 Index, which the advisor considers to be more representative of the fund's investment strategy. The fund's past performance (before

and after taxes) is not necessarily an indication of how the fund will perform in the future. For current performance information, including yields, please visit americancentury.com.

Sales charges and account fees, if applicable, are not reflected in the bar chart. If those charges were included, returns would be less than those shown.

**Example**

The example below is intended to help you compare the costs of investing in the fund with the costs 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 all of your shares at the end of those periods, and that you earn a 5% return each year. The example also assumes that the fund's operating expenses remain the same except that it reflects the rate and duration of any fee waivers noted in the table above. Although your actual costs may be higher or lower, based on these assumptions your costs would be:

**Portfolio Turnover** 

Because the fund buys and sells shares of other American Century mutual funds (the underlying funds) directly from the issuers, the fund is not expected to incur transaction costs directly. However, as a shareholder in the underlying funds, the fund indirectly pays transaction costs, such as commissions, when the underlying funds buy and sell securities (or "turn over" their portfolios). 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 performance. During the most recent fiscal year, the fund's portfolio turnover rate was [14%] of the average value of its portfolio.

**Principal Investment Strategies**

One Choice 2050 Portfolio is a "fund of funds," meaning that it seeks to achieve its objective by investing in other American Century mutual funds (the underlying funds) that represent a variety of asset classes and investment styles. The underlying stock funds draw on growth, value and quantitative investment techniques and diversify investments among small, medium and large U.S. and foreign companies. The underlying bond funds invest in fixed-income securities that vary by issuer type (corporate and government), credit quality (investment-grade and high-yield or "junk bonds") and geographic exposure (domestic and international). Short-term investments include underlying funds that invest in fixed-income or debt instruments and have a shorter-term weighted average duration, typically three years or less. The following table indicates the fund's neutral mix; that is, how the fund's investments generally will be allocated among the major asset classes as of the date of this prospectus.

The target date in the fund name (2050) refers to the approximate year an investor plans to retire and likely would stop making new investments in the fund. The fund assumes a retirement age of 65 and may not be appropriate for an investor who plans to retire at or near the target date, but at an age well before or after 65. As the target date approaches, the fund's neutral mix will become more conservative by decreasing the allocation to stocks and increasing the allocation to bonds and short-term investments. By the time the fund reaches its target date, the neutral mix will become fixed and match that of One Choice In Retirement Portfolio, which is currently 45% stock funds, 47.3% bond funds and 7.7% short-term funds. The fund is designed for investors who plan to withdraw the value of their account gradually after retirement. The following chart shows how the neutral mix is expected to change over time according to a predetermined glide path.

![glidepatha.jpg](glidepatha.jpg)

------

The portfolio managers regularly review the fund's allocations to determine whether rebalancing is appropriate. In order to better balance risks in changing market environments, the portfolio managers may make modest deviations from the neutral mix in light of prevailing market conditions. We reserve the right to modify the neutral mix and underlying funds from time to time should circumstances warrant a change.

**Principal Risks**

• **Allocation Risk** – The fund's performance and risks depend in part on the managers' skill in determining the fund's neutral mix, selecting and weighting the underlying funds, and implementing any deviations from the neutral mix. The managers' evaluations and assumptions regarding asset classes or underlying funds may differ from actual market conditions.

• **Fund of Funds Risks** – The fund's performance and risks reflect the performance and risks of the underlying American Century Investments funds in which it invests. The fund's investment in other American Century Investments funds may create a conflict of interest for the fund's advisor.

• **"Growth" and "Value" Style Risks** – The underlying funds represent a mix of investment styles, each of which has risks associated with it. Growth stocks can be volatile and may lack dividends that can cushion share prices during market declines. Value stocks may continue to be undervalued by the market for long periods of time.

• **Small- and Mid-Cap Stock Risks** – Stocks of smaller companies may be more volatile than larger-company stocks. Smaller companies may have limited financial resources, product lines and markets, and their securities may trade less frequently and in more limited volumes than the securities of larger companies, which could lead to higher transaction costs. To the extent an underlying fund invests in these companies, it may take on more risk.

• **Interest Rate Risk** – Generally, when interest rates rise, the value of an underlying fund's fixed-income securities will decline. The opposite is true when interest rates decline. Underlying funds with longer weighted average maturities are more sensitive to interest rate changes. A period of rising interest rates may negatively affect the performance of underlying fixed-income funds.

• **Credit Risk** – The value of an underlying fund's fixed-income securities will be affected adversely by any erosion in the ability of the issuers of these securities to make interest and principal payments as they become due. Changes in the credit rating of a fixed-income security held by an underlying fund could have a similar effect.

• **Foreign Securities Risk** – Some of the underlying funds invest in foreign securities, which are generally riskier than U.S. securities. Political events, social and economic events, natural disasters and public health emergencies occurring in a country where the fund invests could cause the fund's investments in that country to experience gains or losses. Securities of foreign issuers may be less liquid, more volatile and harder to value than U.S. securities. Fluctuations in currency exchange rates also may affect an underlying fund's share price.

• **Emerging Market Risk** - Investing in securities of companies located in emerging market countries generally is also riskier than investing in securities of companies located in foreign developed countries. Emerging market countries may have unstable governments and/or economies that are subject to sudden change. These changes may be magnified by the countries' emergent financial markets, resulting in significant volatility to investments in these countries.

• **Real Estate Investing Risk** - An investment in the fund may be subject to many of the same risks as a direct investment in real estate. These risks include changes in economic conditions, interest rates, property values, property tax increases, overbuilding and increased competition, environmental contamination, zoning and natural disasters. This is due to the fact that the value of the fund's investments may be affected by the value of the real estate owned by the companies in which it invests.

**• Market Risk** – The value of the fund's shares will go up and down based on the performance of the underlying funds in which it invests. The value of the underlying funds' shares will, in turn, fluctuate based on the performance of the securities they own and other factors generally affecting the securities market. Market risks, including political, regulatory, economic and social developments, can affect the value of the fund's investments. Natural disasters, public health emergencies, war, terrorism and other unforeseeable events may lead to increased market volatility and may have adverse long-term effects on world economies and markets generally.

• **Principal Loss Risk** – At any given time your shares may be worth less than the price you paid for them. In other words, it is possible to lose money by investing in the fund, including losses near to, at, or after retirement. There is no guarantee that the fund will provide adequate income at or through your retirement.

An investment in the fund is not a bank deposit, and it is not insured or guaranteed by the Federal Deposit Insurance Corporation (FDIC) or any other government agency.

**Fund Performance**

The following bar chart and table provide some indication of the risks of investing in the fund. The bar chart shows changes in the fund's performance from year to year for Investor Class shares. The table shows how the fund's average annual returns for the periods shown compared with those of broad measures of market performance. The table also shows returns for the S&P Target Date to 2050 Index, which the advisor considers to be more representative of the fund's investment strategy. The fund's past performance (before

and after taxes) is not necessarily an indication of how the fund will perform in the future. For current performance information, including yields, please visit americancentury.com.

Sales charges and account fees, if applicable, are not reflected in the bar chart. If those charges were included, returns would be less than those shown.

• **Emerging Market Risk** - Investing in securities of companies located in emerging market countries generally is also riskier than investing in securities of companies located in foreign developed countries. Emerging market countries may have unstable governments and/or economies that are subject to sudden change. These changes may be magnified by the countries' emergent financial markets, resulting in significant volatility to investments in these countries.

• **Real Estate Investing Risk** - An investment in the fund may be subject to many of the same risks as a direct investment in real estate. These risks include changes in economic conditions, interest rates, property values, property tax increases, overbuilding and increased competition, environmental contamination, zoning and natural disasters. This is due to the fact that the value of the fund's investments may be affected by the value of the real estate owned by the companies in which it invests.

**• Market Risk** – The value of the fund's shares will go up and down based on the performance of the underlying funds in which it invests. The value of the underlying funds' shares will, in turn, fluctuate based on the performance of the securities they own and other factors generally affecting the securities market. Market risks, including political, regulatory, economic and social developments, can affect the value of the fund's investments. Natural disasters, public health emergencies, war, terrorism and other unforeseeable events may lead to increased market volatility and may have adverse long-term effects on world economies and markets generally.

• **Principal Loss Risk** – At any given time your shares may be worth less than the price you paid for them. In other words, it is possible to lose money by investing in the fund, including losses near to, at, or after retirement. There is no guarantee that the fund will provide adequate income at or through your retirement.

An investment in the fund is not a bank deposit, and it is not insured or guaranteed by the Federal Deposit Insurance Corporation (FDIC) or any other government agency.

**Fund Performance**

The following bar chart and table provide some indication of the risks of investing in the fund. The bar chart shows changes in the fund's performance from year to year for Investor Class shares. The table shows how the fund's average annual returns for the periods shown compared with those of broad measures of market performance. The table also shows returns for the S&P Target Date to 2055 Index, which the advisor considers to be more representative of the fund's investment strategy. The fund's past performance (before

**Payments to Broker-Dealers and Other Financial Intermediaries**

If you purchase the fund through a broker-dealer or other financial intermediary (such as a bank, insurance company, plan sponsor or financial professional), the fund and its related companies may pay the intermediary for the sale of fund shares and related services in all classes except the R6 Class. These payments may create a conflict of interest by influencing the broker-dealer or other intermediary and your salesperson to recommend the fund over another investment. Ask your salesperson or visit your financial intermediary's website for more information.

<sup>2</sup>*&nbsp;&nbsp;&nbsp;&nbsp;The management fee has been restated to reflect current fees.*

<sup>3</sup>*&nbsp;&nbsp;&nbsp;&nbsp;The advisor has agreed to waive a portion of the fund's management fee. The advisor expects this waiver to continue until November 30, 2026 and cannot terminate it prior to such date without the approval of the Board of Directors.*

**Example**

The example below is intended to help you compare the costs of investing in the fund with the costs 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 all of your shares at the end of those periods, and that you earn a 5% return each year. The example also assumes that the fund's operating expenses remain the same except that it reflects the rate and duration of any fee waivers noted in the table above. 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* |
| Investor Class | $91 | $295 | $516 | $1150 |

| R6 Class | $55 | $189 | $334 | $756 |

**Portfolio Turnover**

Because the fund buys and sells shares of other American Century mutual funds (the underlying funds) directly from the issuers, the fund is not expected to incur transaction costs directly. However, as a shareholder in the underlying funds, the fund indirectly pays transaction costs, such as commissions, when the underlying funds buy and sell securities (or "turn over" their portfolios). 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 performance. During the most recent fiscal year, the fund's portfolio turnover rate was [15%] of the average value of its portfolio.

**Principal Investment Strategies**

One Choice 2060 Portfolio is a "fund of funds," meaning that it seeks to achieve its objective by investing in other American Century mutual funds (the underlying funds) that represent a variety of asset classes and investment styles. The underlying stock funds draw on growth, value and quantitative investment techniques and diversify investments among small, medium and large U.S. and foreign companies. The underlying bond funds invest in fixed-income securities that vary by issuer type (corporate and government), credit quality (investment-grade and high-yield or "junk bonds") and geographic exposure (domestic and international). Short-term investments include underlying funds that invest in fixed-income or debt instruments and have a shorter-term weighted average duration, typically three years or less. The following table indicates the fund's neutral mix; that is, how the fund's investments generally will be allocated among the major asset classes as of the date of this prospectus.

---

| | | |
|:---|:---|:---|
| **Equity Securities (Stock Funds)** |  | &nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;**82.5%** |
| &nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;*U.S. Equity* | &nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;*56.8 %* |  |

The target date in the fund name (2060) refers to the approximate year an investor plans to retire and likely would stop making new investments in the fund. The fund assumes a retirement age of 65 and may not be appropriate for an investor who plans to retire at or near the target date, but at an age well before or after 65. As the target date approaches, the fund's neutral mix will become more conservative by decreasing the allocation to stocks and increasing the allocation to bonds and short-term investments. By the time the fund reaches its target date, the neutral mix will become fixed and match that of One Choice In Retirement Portfolio, which is currently 45% stock funds, 47.3% bond funds and 7.7% short-term funds. The fund is designed for investors who plan to withdraw the value of their account gradually after retirement. The following chart shows how the neutral mix is expected to change over time according to a predetermined glide path.

![glidepatha.jpg](glidepatha.jpg)

------

The portfolio managers regularly review the fund's allocations to determine whether rebalancing is appropriate. In order to better balance risks in changing market environments, the portfolio managers may make modest deviations from the neutral mix in light of prevailing market conditions. We reserve the right to modify the neutral mix and underlying funds from time to time should circumstances warrant a change.

**Principal Risks**

• **Allocation Risk** – The fund's performance and risks depend in part on the managers' skill in determining the fund's neutral mix, selecting and weighting the underlying funds, and implementing any deviations from the neutral mix. The managers' evaluations and assumptions regarding asset classes or underlying funds may differ from actual market conditions.

**• Fund of Funds Risks** – The fund's performance and risks reflect the performance and risks of the underlying American Century Investments funds in which it invests. The fund's investment in other American Century Investments funds may create a conflict of interest for the fund's advisor.

• **"Growth" and "Value" Style Risks** – The underlying funds represent a mix of investment styles, each of which has risks associated with it. Growth stocks can be volatile and may lack dividends that can cushion share prices during market declines. Value stocks may continue to be undervalued by the market for long periods of time.

• **Small- and Mid-Cap Stock Risks** – Stocks of smaller companies may be more volatile than larger-company stocks. Smaller companies may have limited financial resources, product lines and markets, and their securities may trade less frequently and in more limited volumes than the securities of larger companies, which could lead to higher transaction costs. To the extent an underlying fund invests in these companies, it may take on more risk.

• **Interest Rate Risk** – Generally, when interest rates rise, the value of an underlying fund's fixed-income securities will decline. The opposite is true when interest rates decline. Underlying funds with longer weighted average maturities are more sensitive to interest rate changes. A period of rising interest rates may negatively affect the performance of underlying fixed-income funds.

• **Credit Risk** – The value of an underlying fund's fixed-income securities will be affected adversely by any erosion in the ability of the issuers of these securities to make interest and principal payments as they become due. Changes in the credit rating of a fixed-income security held by an underlying fund could have a similar effect.

• **Foreign Securities Risk** – Some of the underlying funds invest in foreign securities, which are generally riskier than U.S. securities. Political events, social and economic events, natural disasters and public health emergencies occurring in a country where the fund invests could cause the fund's investments in that country to experience gains or losses. Securities of foreign issuers may be less liquid, more volatile and harder to value than U.S. securities. Fluctuations in currency exchange rates also may affect an underlying fund's share price.

• **Emerging Market Risk** - Investing in securities of companies located in emerging market countries generally is also riskier than investing in securities of companies located in foreign developed countries. Emerging market countries may have unstable governments and/or economies that are subject to sudden change. These changes may be magnified by the countries' emergent financial markets, resulting in significant volatility to investments in these countries.

• **Real Estate Investing Risk** - An investment in the fund may be subject to many of the same risks as a direct investment in real estate. These risks include changes in economic conditions, interest rates, property values, property tax increases, overbuilding and increased competition, environmental contamination, zoning and natural disasters. This is due to the fact that the value of the fund's investments may be affected by the value of the real estate owned by the companies in which it invests.

**• Market Risk** – The value of the fund's shares will go up and down based on the performance of the underlying funds in which it invests. The value of the underlying funds' shares will, in turn, fluctuate based on the performance of the securities they own and other factors generally affecting the securities market. Market risks, including political, regulatory, economic and social developments, can affect the value of the fund's investments. Natural disasters, public health emergencies, war, terrorism and other unforeseeable events may lead to increased market volatility and may have adverse long-term effects on world economies and markets generally.

• **Principal Loss Risk** – At any given time your shares may be worth less than the price you paid for them. In other words, it is possible to lose money by investing in the fund, including losses near to, at, or after retirement. There is no guarantee that the fund will provide adequate income at or through your retirement.

An investment in the fund is not a bank deposit, and it is not insured or guaranteed by the Federal Deposit Insurance Corporation (FDIC) or any other government agency.

Fund distributions are generally taxable as ordinary income or capital gains, unless you are investing through a tax-deferred account such as a 401(k) or individual retirement account (in which case you may be taxed upon withdrawal of your investment from such account).

**Payments to Broker-Dealers and Other Financial Intermediaries**

If you purchase the fund through a broker-dealer or other financial intermediary (such as a bank, insurance company, plan sponsor or financial professional), the fund and its related companies may pay the intermediary for the sale of fund shares and related services in all classes except the R6 Class. These payments may create a conflict of interest by influencing the broker-dealer or other intermediary and your salesperson to recommend the fund over another investment. Ask your salesperson or visit your financial intermediary's website for more information.

**Example**

The example below is intended to help you compare the costs of investing in the fund with the costs 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 all of your shares at the end of those periods, and that you earn a 5% return each year. The example also assumes that the fund's operating expenses remain the same except that it reflects the rate and duration of any fee waivers noted in the table above. Although your actual costs may be higher or lower, based on these assumptions your costs would be:

**Portfolio Turnover** 

Because the fund buys and sells shares of other American Century mutual funds (the underlying funds) directly from the issuers, the fund is not expected to incur transaction costs directly. However, as a shareholder in the underlying funds, the fund indirectly pays transaction costs, such as commissions, when the underlying funds buy and sell securities (or "turn over" their portfolios). 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 performance. During the most recent fiscal year, the fund's portfolio turnover rate was [8%] of the average value of its portfolio.

**Principal Investment Strategies**

One Choice 2065 Portfolio is a "fund of funds," meaning that it seeks to achieve its objective by investing in other American Century mutual funds (the underlying funds) that represent a variety of asset classes and investment styles. The underlying stock funds draw on growth, value and quantitative investment techniques and diversify investments among small, medium and large U.S. and foreign companies. The underlying bond funds invest in fixed-income securities that vary by issuer type (corporate and government), credit quality (investment-grade and high-yield or "junk bonds") and geographic exposure (domestic and international). Short-term investments include underlying funds that invest in fixed-income or debt instruments and have a shorter-term weighted average duration, typically three years or less. The following table indicates the fund's neutral mix; that is, how the fund's investments generally will be allocated among the major asset classes as of the date of this prospectus.

The target date in the fund name (2065) refers to the approximate year an investor plans to retire and likely would stop making new investments in the fund. The fund assumes a retirement age of 65 and may not be appropriate for an investor who plans to retire at or near the target date, but at an age well before or after 65. As the target date approaches, the fund's neutral mix will become more conservative by decreasing the allocation to stocks and increasing the allocation to bonds and short-term investments. By the time the fund reaches its target date, the neutral mix will become fixed and match that of One Choice In Retirement Portfolio, which is currently 45% stock funds, 47.3% bond funds and 7.7% short-term funds. The fund is designed for investors who plan to withdraw the value of their account gradually after retirement. The following chart shows how the neutral mix is expected to change over time according to a predetermined glide path.

![glidepatha.jpg](glidepatha.jpg)

------

The portfolio managers regularly review the fund's allocations to determine whether rebalancing is appropriate. In order to better balance risks in changing market environments, the portfolio managers may make modest deviations from the neutral mix in light of prevailing market conditions. We reserve the right to modify the neutral mix and underlying funds from time to time should circumstances warrant a change.

**Principal Risks**

• **Allocation Risk** – The fund's performance and risks depend in part on the managers' skill in determining the fund's neutral mix, selecting and weighting the underlying funds, and implementing any deviations from the neutral mix. The managers' evaluations and assumptions regarding asset classes or underlying funds may differ from actual market conditions.

**• Fund of Funds Risks** – The fund's performance and risks reflect the performance and risks of the underlying American Century Investments funds in which it invests. The fund's investment in other American Century Investments funds may create a conflict of interest for the fund's advisor.

• **"Growth" and "Value" Style Risks** – The underlying funds represent a mix of investment styles, each of which has risks associated with it. Growth stocks can be volatile and may lack dividends that can cushion share prices during market declines. Value stocks may continue to be undervalued by the market for long periods of time.

• **Small- and Mid-Cap Stock Risks** – Stocks of smaller companies may be more volatile than larger-company stocks. Smaller companies may have limited financial resources, product lines and markets, and their securities may trade less frequently and in more limited volumes than the securities of larger companies, which could lead to higher transaction costs. To the extent an underlying fund invests in these companies, it may take on more risk.

• **Interest Rate Risk** – Generally, when interest rates rise, the value of an underlying fund's fixed-income securities will decline. The opposite is true when interest rates decline. Underlying funds with longer weighted average maturities are more sensitive to interest rate changes. A period of rising interest rates may negatively affect the performance of underlying fixed-income funds.

• **Credit Risk** – The value of an underlying fund's fixed-income securities will be affected adversely by any erosion in the ability of the issuers of these securities to make interest and principal payments as they become due. Changes in the credit rating of a fixed-income security held by an underlying fund could have a similar effect.

• **Foreign Securities Risk** – Some of the underlying funds invest in foreign securities, which are generally riskier than U.S. securities. Political events, social and economic events, natural disasters and public health emergencies occurring in a country where the fund invests could cause the fund's investments in that country to experience gains or losses. Securities of foreign issuers may be less liquid, more volatile and harder to value than U.S. securities. Fluctuations in currency exchange rates also may affect an underlying fund's share price.

• **Emerging Market Risk** - Investing in securities of companies located in emerging market countries generally is also riskier than investing in securities of companies located in foreign developed countries. Emerging market countries may have unstable governments and/or economies that are subject to sudden change. These changes may be magnified by the countries' emergent financial markets, resulting in significant volatility to investments in these countries.

• **Real Estate Investing Risk** - An investment in the fund may be subject to many of the same risks as a direct investment in real estate. These risks include changes in economic conditions, interest rates, property values, property tax increases, overbuilding and increased competition, environmental contamination, zoning and natural disasters. This is due to the fact that the value of the fund's investments may be affected by the value of the real estate owned by the companies in which it invests.

• **Market Risk** – The value of the fund's shares will go up and down based on the performance of the underlying funds in which it invests. The value of the underlying funds' shares will, in turn, fluctuate based on the performance of the securities they own and other factors generally affecting the securities market. Market risks, including political, regulatory, economic and social developments, can affect the value of the fund's investments. Natural disasters, public health emergencies, war, terrorism and other unforeseeable events may lead to increased market volatility and may have adverse long-term effects on world economies and markets generally.

• **Principal Loss Risk** – At any given time your shares may be worth less than the price you paid for them. In other words, it is possible to lose money by investing in the fund, including losses near to, at, or after retirement. There is no guarantee that the fund will provide adequate income at or through your retirement.

An investment in the fund is not a bank deposit, and it is not insured or guaranteed by the Federal Deposit Insurance Corporation (FDIC) or any other government agency.

**Fund Performance**

The following bar chart and table provide some indication of the risks of investing in the fund. The bar chart shows changes in the fund's performance from year to year for Investor Class shares. The table shows how the fund's average annual returns for the periods shown compared with those of broad measures of market performance. The table also shows returns for the S&P Target Date to 2065+ Index, which the advisor considers to be more representative of the fund's investment strategy. The fund's past performance (before

and after taxes) is not necessarily an indication of how the fund will perform in the future. For current performance information, including yields, please visit americancentury.com.

Sales charges and account fees, if applicable, are not reflected in the bar chart. If those charges were included, returns would be less than those shown.

The after-tax returns are shown only for Investor Class shares. After-tax returns for other share classes will vary. After-tax returns are calculated using the historical highest individual federal marginal income tax rates and do not reflect the impact of state and local taxes. Actual after-tax returns depend on an investor's tax situation and may differ from those shown. After-tax returns are not relevant to investors who hold their fund shares through tax-deferred arrangements, such as 401(k) plans or IRAs.

**Portfolio Turnover**

Because the fund buys and sells shares of other American Century mutual funds (the underlying funds) directly from the issuers, the fund is not expected to incur transaction costs directly. However, as a shareholder in the underlying funds, the fund indirectly pays transaction costs, such as commissions, when the underlying funds buy and sell securities (or "turn over" their portfolios). 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 performance. Because the fund is new, the fund's portfolio turnover rate is not available

The target date in the fund name (2070) refers to the approximate year an investor plans to retire and likely would stop making new investments in the fund. The fund assumes a retirement age of 65 and may not be appropriate for an investor who plans to retire at or near the target date, but at an age well before or after 65. As the target date approaches, the fund's neutral mix will become more conservative by decreasing the allocation to stocks and increasing the allocation to bonds and short-term investments. By the time the fund reaches its target date, the neutral mix will become fixed and match that of One Choice In Retirement Portfolio, which is currently 45% stock funds, 47.3% bond funds and 7.7% short-term funds. The fund is designed for investors who plan to withdraw the value of their account gradually after retirement. The following chart shows how the neutral mix is expected to change over time according to a predetermined glide path.

![glidepatha.jpg](glidepatha.jpg)

------

The portfolio managers regularly review the fund's allocations to determine whether rebalancing is appropriate. In order to better balance risks in changing market environments, the portfolio managers may make modest deviations from the neutral mix in light of prevailing market conditions. We reserve the right to modify the neutral mix and underlying funds from time to time should circumstances warrant a change.

**Principal Risks**

• **Allocation Risk** – The fund's performance and risks depend in part on the managers' skill in determining the fund's neutral mix, selecting and weighting the underlying funds, and implementing any deviations from the neutral mix. The managers' evaluations and assumptions regarding asset classes or underlying funds may differ from actual market conditions.

**•** **Fund of Funds Risks** – The fund's performance and risks reflect the performance and risks of the underlying American Century Investments funds in which it invests. The fund's investment in other American Century Investments funds may create a conflict of interest for the fund's advisor.

• **"Growth" and "Value" Style Risks** – The underlying funds represent a mix of investment styles, each of which has risks associated with it. Growth stocks can be volatile and may lack dividends that can cushion share prices during market declines. Value stocks may continue to be undervalued by the market for long periods of time.

• **Small- and Mid-Cap Stock Risks** – Stocks of smaller companies may be more volatile than larger-company stocks. Smaller companies may have limited financial resources, product lines and markets, and their securities may trade less frequently and in more limited volumes than the securities of larger companies, which could lead to higher transaction costs. To the extent an underlying fund invests in these companies, it may take on more risk.

• **Interest Rate Risk** – Generally, when interest rates rise, the value of an underlying fund's fixed-income securities will decline. The opposite is true when interest rates decline. Underlying funds with longer weighted average maturities are more sensitive to interest rate changes. A period of rising interest rates may negatively affect the performance of underlying fixed-income funds.

• **Credit Risk** – The value of an underlying fund's fixed-income securities will be affected adversely by any erosion in the ability of the issuers of these securities to make interest and principal payments as they become due. Changes in the credit rating of a fixed-income security held by an underlying fund could have a similar effect.

• **Foreign Securities Risk** – Some of the underlying funds invest in foreign securities, which are generally riskier than U.S. securities. Political events, social and economic events, natural disasters and public health emergencies occurring in a country where the fund invests could cause the fund's investments in that country to experience gains or losses. Securities of foreign issuers may be less liquid, more volatile and harder to value than U.S. securities. Fluctuations in currency exchange rates also may affect an underlying fund's share price.

• **Emerging Market Risk** - Investing in securities of companies located in emerging market countries generally is also riskier than investing in securities of companies located in foreign developed countries. Emerging market countries may have unstable governments and/or economies that are subject to sudden change. These changes may be magnified by the countries' emergent financial markets, resulting in significant volatility to investments in these countries.

• **Real Estate Investing Risk** - An investment in the fund may be subject to many of the same risks as a direct investment in real estate. These risks include changes in economic conditions, interest rates, property values, property tax increases, overbuilding and increased competition, environmental contamination, zoning and natural disasters. This is due to the fact that the value of the fund's investments may be affected by the value of the real estate owned by the companies in which it invests.

• **Market Risk** – The value of the fund's shares will go up and down based on the performance of the underlying funds in which it invests. The value of the underlying funds' shares will, in turn, fluctuate based on the performance of the securities they own and other factors generally affecting the securities market. Market risks, including political, regulatory, economic and social developments, can affect the value of the fund's investments. Natural disasters, public health emergencies, war, terrorism and other unforeseeable events may lead to increased market volatility and may have adverse long-term effects on world economies and markets generally.

• **Principal Loss Risk** – At any given time your shares may be worth less than the price you paid for them. In other words, it is possible to lose money by investing in the fund, including losses near to, at, or after retirement. There is no guarantee that the fund will provide adequate income at or through your retirement.

An investment in the fund is not a bank deposit, and it is not insured or guaranteed by the Federal Deposit Insurance Corporation (FDIC) or any other government agency.

**Fund Performance**

Because the fund is new, the fund does not have performance history as of the date of this prospectus. When the fund has investment results for a full calendar year, this section will feature charts that show annual total returns, highest and lowest quarterly returns and average annual total returns for the fund. This information indicates the volatility of the fund's historical returns from year to year.

Unless otherwise specified below, the minimum initial investment amount to open an account is $2,500 ($1,000 for Coverdell Education Savings Accounts and IRAs). However, American Century Investments will waive the fund minimum if you make an initial investment of at least $500 and continue to make automatic investments of at least $100 a month until reaching the fund minimum. Investors opening accounts through financial intermediaries may open an account with $250 for Investor, A, C and R Classes, but the financial intermediaries may require their clients to meet different investment minimums. The minimum may be waived for broker-dealer sponsored wrap program accounts, fee based accounts, and accounts through bank/trust and wealth management advisory organizations.

The minimum initial investment amount for I Class is generally $5 million ($3 million for endowments and foundations), but the minimum may be waived if you have an aggregate investment in the American Century family of funds of $10 million or more ($5 million for endowments and foundations). This includes accounts held directly with American Century and those held through a financial intermediary.

There is no minimum initial investment amount for R6 Class shares.

For all share classes, there is no minimum initial investment amount for certain employer-sponsored retirement plans, however, financial intermediaries or plan recordkeepers may require plans to meet different minimums. There is a $50 minimum for subsequent purchases, except that there is no subsequent purchase minimum for financial intermediaries or employer-sponsored retirement plans.

**Tax Information**

Fund distributions are generally taxable as ordinary income or capital gains, unless you are investing through a tax-deferred account such as a 401(k) or individual retirement account (in which case you may be taxed upon withdrawal of your investment from such account).

**Payments to Broker-Dealers and Other Financial Intermediaries**

If you purchase the fund through a broker-dealer or other financial intermediary (such as a bank, insurance company, plan sponsor or financial professional), the fund and its related companies may pay the intermediary for the sale of fund shares and related services in all classes except the R6 Class. These payments may create a conflict of interest by influencing the broker-dealer or other intermediary and your salesperson to recommend the fund over another investment. Ask your salesperson or visit your financial intermediary's website for more information.

**Objectives, Strategies and Risks**

**What are the funds' investment objectives?** 

One Choice In Retirement Portfolio seeks current income. Capital appreciation is a secondary objective.

Each of One Choice 2030, 2035, 2040, 2045, 2050, 2055, 2060, 2065 and 2070 Portfolios seeks the highest ***total return*** consistent with its asset mix.

***Total return*** *includes capital appreciation plus dividend and interest income.*<br>

Each of One Choice 2060 and 2065 Portfolios' objective is a nonfundamental investment policy and may be changed by the Board of Directors without shareholder approval upon 60 days' notice to the shareholders.

**What are the funds' principal investment strategies?**

Each fund invests in a combination of underlying American Century Investments funds. Each fund's neutral mix is intended to diversify investments among various asset classes such as stocks, bonds and short-term investments. The neutral mix for One Choice In Retirement Portfolio is expected to remain fixed over time. For each fund with a target date, the neutral mix will be adjusted in a step-like fashion. For example, assume the current stock weighting in One Choice 2035 Portfolio is approximately 55% and the stock weighting in One Choice 2030 Portfolio is approximately 50%. Over time, we would expect to reduce the stock weighting in One Choice 2035 Portfolio. Over a five year period the stock weighting would be reduced to approximately 50%. In effect, One Choice 2035 Portfolio is expected to have the same stock weighting in five years as One Choice 2030 Portfolio has now. By the time each fund reaches its target date, its neutral mix will become fixed and will match that of One Choice In Retirement Portfolio, which is currently 45% stock funds, 47.3% bond funds and 7.7% short-term funds.

A fund with an earlier target date represents a more conservative choice. A fund with a later target date represents a more aggressive choice. The target date does not necessarily represent the specific year you expect to need your assets. It is intended only as a general guide and assumes a retirement age of 65.

The following table shows each fund's neutral mix as of the date of this prospectus.

In order to better balance risks in changing market environments, the portfolio managers may make modest deviations from the neutral mix in light of prevailing market conditions. We reserve the right to modify the neutral mix and underlying funds from time to time should circumstances warrant a change.

The portfolio managers regularly review each fund to determine whether rebalancing is appropriate.

A description of the policies and procedures with respect to the disclosure of the funds' portfolio securities is available in the statement of additional information.

------

**What are the underlying funds' investment techniques?**

The underlying stock funds draw on growth, value and quantitative investment techniques and diversify investments among small, medium and large U.S. companies. They also include investments in the real estate sector as well as foreign stocks from developed and emerging markets.

The growth strategy looks for stocks of companies the portfolio managers believe will increase in value over time. In implementing this strategy, the portfolio managers use a variety of analytical research tools and techniques to identify stocks of companies demonstrating accelerating earnings or revenue growth rates, stock price momentum, increasing cash flows, or other indications of the relative strength of a company's business. The value investment discipline seeks capital growth by investing in equity securities of companies that the funds' portfolio managers believe to be temporarily undervalued. For underlying funds that are quantitatively managed, the managers utilize quantitative, computer-driven models to construct and manage portfolios that they believe provide the optimal balance between risk and expected return.

The underlying bond funds represent a diverse range of fixed-income investments that vary by issuer type (corporate and government), credit quality (investment-grade and high-yield or "junk bonds") and geographic exposure (domestic and international).

Short-term investments include underlying funds that invest in fixed-income or debt instruments and have a shorter-term weighted average duration, typically three years or less.

A brief description of the underlying funds follows. Each fund invests in some, but not necessarily all, of the underlying funds listed, and may also invest in other American Century funds that are not listed. Each fund's full portfolio holdings are posted on americancentury.com on a quarterly basis. Additional details regarding the strategies and risks of the underlying funds are available in the statement of additional information and the underlying funds' prospectuses, which are also available at americancentury.com.

*International Value Fund* seeks long-term capital growth. It uses a quantitative investment strategy to construct an optimized portfolio drawn primarily from securities of companies located outside the United States that are believed to be undervalued by the market.

------

*Non-U.S. Intrinsic Value Fund* seeks capital appreciation. The fund invests in non-U.S. companies that are believed to be trading at significant discounts to their intrinsic value.

**Real Estate** 

*Global Real Estate Fund* seeks high total investment return through a combination of capital appreciation and current income. It invests primarily in equity securities issued by real estate investment trusts (REITs) and other companies engaged in the real estate industry located in developed countries world-wide.

**Bond Funds**

*Diversified Bond Fund* seeks a high level of income by investing primarily in high- and medium-grade non-money market debt securities. These securities, which may be payable in U.S. or foreign currencies, may include corporate bonds and notes, government securities and securities backed by mortgages or other assets.

*Emerging Markets Debt Fund* seeks total return by investing in fixed income instruments of issuers that are economically tied to emerging markets.

*Global Bond Fund* seeks long-term total return by investing primarily in government and corporate bonds, which may be payable in U.S. or foreign currencies.

*High Income Fund* seeks current yield and capital growth. The fund invests primarily in high-yield corporate bonds and other debt instruments with an emphasis on those that are rated below investment grade.

*Inflation-Adjusted Bond Fund* seeks to provide total return and inflation protection consistent with investment in inflation-indexed securities.

*Short Duration Inflation Protection Bond Fund* pursues total return using a strategy that seeks to protect against U.S. inflation. The fund invests primarily in inflation-linked debt securities and the weighted average duration of its portfolio must be five years or shorter.

**Short-Term Funds**

*Short Duration Fund* seeks to maximize total return and, as a secondary objective, seeks a high level of income. The fund invests primarily in investment-grade debt securities and its weighted average duration must be three years or less.

**What are the principal risks of investing in the funds?**

Each fund's performance and risks depend in part on the managers' skill in determining the fund's neutral mix, selecting and weighting the underlying funds, and implementing any deviations from the neutral mix. There is a risk that the managers' evaluations and assumptions regarding asset classes or underlying funds may differ from actual market conditions.

Each fund's performance and risks reflect the performance and risks of the underlying American Century Investments funds in which it invests. Some of these risks relate to investments in stocks. Others relate primarily to fixed-income or foreign investments. The degree to which the risks described below apply to a particular fund varies according to its asset allocation.

The fund may hold a significant percentage of the shares of an underlying fund. As a result, the fund's investments in an underlying American Century Investments fund may create a conflict of interest for the advisor.

Market performance tends to be cyclical. In the various cycles, certain investment styles, such as growth and value styles, may fall in and out of favor. If the market is not favoring an underlying fund's style, that fund's gains may not be as big as, or its losses may be bigger than, those of other equity funds using different investment styles.

Growth stocks are typically priced higher than other stocks, in relation to earnings and other measures, because investors believe they have more growth potential. This potential may or may not be realized. If the portfolio managers' assessment of a company's prospects for earnings or growth or how other investors will value the company's earnings growth is incorrect, the price of the company's stock may fall or fail to reach the value the managers have placed on it. Growth stock prices tend to fluctuate more dramatically than the overall stock market.

Similarly, if the market does not consider the individual stocks purchased by a value fund to be undervalued, the fund's shares may not rise as high as other funds and may in fact decline, even if stock prices generally are increasing.

Underlying funds that invest in mid-sized and smaller companies may be more volatile, and subject to greater short-term risk, than funds that invest in larger companies. Smaller companies may have limited financial resources, product lines and markets, and their securities may trade less frequently and in more limited volumes than the securities of larger companies. In addition, smaller companies may have less publicly available information.

The value of an underlying fund's ***fixed-income securities*** will be affected by rising or falling interest rates. Generally interest rates and the prices of debt securities move in opposite directions. When interest rates fall, the prices of most debt securities rise; when

------

interest rates rise, prices fall. Funds with longer weighted maturities are more sensitive to interest rate changes. A period of rising interest rates may negatively affect the funds' performance.

***Fixed-income securities*** *are rated by nationally recognized securities rating organizations (SROs), such as Moody's and Standard & Poor's. Each SRO has its own system for classifying securities, but each tries to indicate a company's ability to make timely payments of interest and principal*.<br>

The value of an underlying fund's fixed-income securities also will be affected by the inability or perceived inability of the issuers of these securities to make payments of interest and principal as they become due.

The lowest-rated investment-grade bonds in which the underlying funds may invest contain some speculative characteristics. Having those bonds in the funds' portfolios means the funds' values may go down more if interest rates or other economic conditions change than if the funds contained only higher-rated bonds. In addition, higher-risk high-yield securities, which are below investment-grade and sometimes referred to as junk bonds, are considered to be predominantly speculative and are more likely to be negatively affected by changes in interest rates or other economic conditions.

Some of the underlying funds invest in foreign securities. Foreign investment involves additional risks, including fluctuations in currency exchange rates, less stable political and economic structures, reduced availability of public information, and lack of uniform financial reporting and regulatory practices similar to those that apply in the United States. These factors make investing in foreign securities generally riskier than investing in U.S. securities. Securities of foreign issuers may be less liquid, more volatile and harder to value than U.S. securities. Investing in securities of companies located in emerging market countries is also riskier than investing in securities of companies located in foreign developed countries.

Investing in securities of issuers located in emerging market countries generally is riskier than investing in securities of companies located in foreign developed countries. Emerging market countries may have unstable governments and/or economies that are subject to sudden change. These changes may be magnified by the countries' emergent financial markets, resulting in significant volatility to investments in these countries. These countries also may lack the legal, business and social framework to support securities markets.

An investment in the fund may be subject to many of the same risks as a direct investment in real estate. These risks include changes in economic conditions, interest rates, property values, property tax increases, overbuilding and increased competition, environmental contamination, zoning and natural disasters. This is due to the fact that the value of the fund's investments may be affected by the value of the real estate owned by the companies in which it invests.

The value of an underlying fund's shares depends on the value of the stocks and other securities it owns. The value of the individual securities a fund owns will go up and down, depending on the performance of the companies that issued them, general market and economic conditions, and investor confidence. Market risks, including political, regulatory, economic and social developments, can affect the value of the fund's investments. Natural disasters, public health emergencies, war, terrorism and other unforeseeable events may lead to increased market volatility and may have adverse long-term effects on world economies and markets generally.

These funds are intended for investors who seek a diversified investment whose asset mix becomes more conservative over time, and who are willing to accept the risks associated with the funds' multi-asset strategies.

A fund may need to sell securities at times it would not otherwise do so in order to meet shareholder redemption requests. A fund could experience a loss when selling securities, particularly if the redemption requests are unusually large or frequent, occur in times of overall market turmoil or declining pricing for the securities sold or when the securities the fund wishes to sell are illiquid. Selling securities to meet such redemption requests also may increase transaction costs and/or have tax consequences. To the extent that a large shareholder (including another account advised by the advisor, a fund of funds or 529 college savings plan) invests in a fund, the fund may experience relatively large redemptions as such shareholder reallocates its assets. Although the advisor seeks to minimize the impact of such transactions where possible, a fund's performance may be adversely affected.

At any given time your shares may be worth less than the price you paid for them. In other words, it is possible to lose money by investing in the funds, including losses near to, at, or after retirement. There is no guarantee that a fund will provide adequate income at or through your retirement.

**What will happen when a fund reaches its target date?**

When a fund reaches its most conservative planned neutral mix, which is expected to occur on approximately November 30 of the year before the target date, its neutral mix will become fixed and will match that of One Choice In Retirement Portfolio. Thereafter, the fund's Board of Directors, without a vote of shareholders, may approve combining such fund with One Choice In Retirement Portfolio. Although such combination of assets is intended to qualify as a tax-free reorganization, the fund may realize capital gains or losses prior to the combination and fund shareholders may receive a taxable distribution. Once the combination occurs, shareholders of the fund will become shareholders of One Choice In Retirement Portfolio.

------

**Management**

**Who manages the funds?** 

The Board of Directors, investment advisor and fund management team play key roles in the management of the funds.

**The Board of Directors** 

The Board of Directors is responsible for overseeing the advisor's management and operations of the funds pursuant to the management agreement. In performing their duties, Board members receive detailed information about the funds and their advisor regularly throughout the year, and meet at least quarterly with management of the advisor to review reports about fund operations. The directors' role is to provide oversight and not to provide day-to-day management. More than three-fourths of the directors are independent of the funds' advisor. They are not employees, directors or officers of, and have no financial interest in, the advisor or any of its affiliated companies (other than as shareholders of American Century Investments funds), and they do not have any other affiliations, positions or relationships that would cause them to be considered "interested persons" under the Investment Company Act of 1940. The directors also serve in that capacity for many of the underlying funds.

**The Investment Advisor** 

The funds' investment advisor is American Century Investment Management, Inc. (the advisor). The advisor has been managing mutual funds since 1958 and is headquartered at 4500 Main Street, Kansas City, Missouri 64111.

The advisor is responsible for managing the investment portfolios of the funds and directing the purchase and sale of the underlying American Century Investments funds in which they invest. The advisor also arranges for transfer agency, custody and all other services necessary for the funds to operate. Additionally, the advisor is responsible for the selection and management of the underlying funds' portfolio investments.

For certain services it provides to each fund and the underlying funds, the advisor receives a unified management fee based on a percentage of the daily net assets of each class of shares of the fund. The amount of the fee is calculated daily and paid monthly in arrears. Out of that fee, the advisor pays all expenses of managing and operating that fund except brokerage expenses, taxes, interest, fees and expenses of the independent directors (including legal counsel fees), extraordinary expenses, and expenses incurred in connection with the provision of shareholder services and distribution services under a plan adopted pursuant to Rule 12b-1 under the Investment Company Act of 1940. The difference in unified management fees among the classes is a result of their separate arrangements for non-Rule 12b-1 shareholder services. It is not the result of any difference in advisory or custodial fees or other expenses related to the management of the fund's assets, which do not vary by class. For all classes other than the R6 Class, the advisor may pay unaffiliated third parties who provide recordkeeping and administrative services that would otherwise be performed by an affiliate of the advisor. Because One Choice 2070 Portfolio is new, it is not included in the table. **[Table to be updated]**

**Investing Through a Financial Intermediary**

Each fund may be purchased by participants in employer-sponsored retirement plans or through ***financial intermediaries*** that provide various administrative and distribution services.

***Financial intermediaries*** *include banks, broker-dealers, insurance companies, plan sponsors and financial professionals*.<br>

Although each class of a fund's shares represents an interest in the same fund, each has a different cost structure, as described below. Which class is right for you depends on many factors, including how long you plan to hold the shares, how much you plan to invest, the fee structure of each class, and how you wish to compensate your financial professional for the services provided to you. Your financial professional can help you choose the option that is most appropriate.

**Investor Class**

Investor Class shares are available for purchase without sales charges or commissions but may be subject to account or transaction fees if purchased through financial intermediaries. These shares are available to investors in retail brokerage accounts, broker-dealer-sponsored fee-based advisory accounts, other advisory accounts where fees are charged, and employer-sponsored retirement plans.

**I Class**

I Class shares are available for purchase without sales charges or commissions by endowments, foundations, large institutional investors, employer-sponsored retirement plans and financial intermediaries.

**A Class** 

A Class shares are available for purchase through broker-dealers and other financial intermediaries. These shares carry an initial sales charge and an ongoing distribution and service (12b-1) fee that is used to compensate your financial professional. See *Calculation of Sales Charges* below for commission amounts received by financial professionals on the purchase of A Class shares. The sales charge decreases with the size of the purchase, and may be reduced or eliminated in certain situations. See *Reductions and Waivers of Sales Charges for A Class* and *CDSC Waivers* below for a full description of the breakpoints, reductions and waivers that may be available through financial intermediaries in certain types of accounts or products.

**C Class**

C Class shares are available for purchase through broker-dealers and other financial intermediaries. These shares do not have an initial sales charge but carry an ongoing distribution and service (12b-1) fee. Except as noted below, the commission paid to your financial professional for purchases of C Class shares is 1.00% of the amount invested, and the shares have a contingent deferred sales charge (CDSC) when redeemed within one year of purchase. Your financial professional does not receive the distribution and service (12b-1) fee until the CDSC period has expired (it is retained by the distributor). See *CDSC Waivers* below for a full description of the waivers that may be available. C Class shares automatically convert to A Class shares 8 years after purchase.

**R Class**

R Class shares do not carry a sales charge or commission, but they have an ongoing distribution and service (12b-1) fee. R Class shares are available for purchase through certain employer-sponsored retirement plans. R Class shares also may be available for certain other accounts through financial intermediaries who have an agreement with us to offer the R Class in certain products. Additionally, IRA accounts in R Class shares established through financial intermediaries prior to August 1, 2006, may make additional purchases. With respect to purchases through financial intermediaries, R Class shares are not available in the following types of employer-sponsored retirement plans: SEP IRAs, SIMPLE IRAs or SARSEPs, except that investors in such plans with accounts in R Class shares established prior to March 1, 2009, may make additional purchases, and certain intermediaries may have agreements with us to offer R Class shares in such plans as described above.

**R6 Class**

R6 Class shares are available for purchase without sales charges or commissions by participants in certain employer-sponsored retirement plans. R6 Class shares may be purchased or redeemed only through employer-sponsored retirement plans where a financial intermediary provides retirement recordkeeping services to plan participants.

------

**Calculation of Sales Charges**

The information regarding sales charges provided herein is included free of charge and in a clear and prominent format at americancentury.com in the *Investors Using Advisors* and *Investment Professionals* portions of the website. From the description of A or C Class shares, a hyperlink will take you directly to this disclosure.

The availability of the sales charge reductions and waivers discussed below will depend upon whether you purchase your shares directly from the fund or through a financial intermediary. Intermediaries may have different policies and procedures regarding the availability of these reductions or waivers. Please refer to *Appendix A* for information provided by certain financial intermediaries regarding their sales charge waiver or discount policies that are applicable to investors transacting in fund shares through such financial intermediary.

**A Class**

A Class shares are sold at their offering price, which is net asset value plus an initial sales charge. This sales charge varies depending on the amount of your investment, and is deducted from your purchase before it is invested. The sales charges and the amounts paid to your financial professional are:

---

| | | | |
|:---|:---|:---|:---|
| *Purchase Amount* | *Sales Charge as a %<br>of Offering Price* | *Sales Charge as a %<br>of Net Amount Invested* | *Dealer Commission<br>as a % of Offering Price* |
| Less than $50,000 | 5.75% | 6.10% | 5.00% |
| $50000 - $99999 | 4.75% | 4.99% | 4.00% |
| $100000 - $249999 | 3.75% | 3.90% | 3.25% |
| $250000 - $499999 | 2.50% | 2.56% | 2.00% |
| $500000 - $999999 | 2.00% | 2.04% | 1.75% |
| $1000000 - $3999999 | 0.00% | 0.00% | 1.00% |
| $4000000 - $9999999 | 0.00% | 0.00% | 0.50% |
| $10,000,000 or more | 0.00% | 0.00% | 0.25% |

---

There is no front-end sales charge for purchases of $1,000,000 or more, but if you redeem your shares within one year of purchase you will pay a deferred sales charge of 1.00% of the lower of the original purchase price or the current market value at redemption, subject to the exceptions listed below. No sales charge applies to reinvested dividends. No dealer commission will be paid to your financial professional for purchases by certain employer-sponsored retirement plans. For this purpose, employer-sponsored retirement plans do not include SEP IRAs, SIMPLE IRAs or SARSEPs.

**Reductions and Waivers of Sales Charges for A Class** 

You may qualify for a reduction or waiver of certain sales charges, but you or your financial professional must provide certain information, including the account numbers of any accounts to be aggregated, to American Century Investments at the time of purchase in order to take advantage of such reduction or waiver. If you hold assets among multiple intermediaries, it is your responsibility to inform your intermediary and/or American Century Investments at the time of purchase, of any accounts to be aggregated.

You and your immediate family (which includes your spouse or domestic partner and children, step-children, parents or step-parents of you, your spouse or domestic partner) may combine investments in any share class of any American Century Investments mutual fund (excluding certain assets in money market accounts, but including account assets invested in Qualified Tuition Programs under Section 529) to reduce your A Class sales charge in the following ways:

*Account Aggregation*. Investments made by you and your immediate family may be aggregated at each account's current market value if made for your own account(s) and/or certain other accounts, such as:

• Certain trust accounts

• Solely controlled business accounts

• Single-participant retirement plans

• Endowments or foundations established and controlled by you or an immediate family member

For purposes of aggregation, only investments made through individual-level accounts may be combined. Assets held in multiple participant employer-sponsored retirement plans may be aggregated at a plan level.

*Concurrent Purchases*. You may combine simultaneous purchases in any share class of any American Century Investments mutual fund to qualify for a reduced A Class sales charge.

*Rights of Accumulation.* You may take into account the current value of your existing holdings, less any commissionable shares in the money market funds, in any share class of any American Century Investments mutual fund to qualify for a reduced A Class sales charge. An investor who purchases fund shares through a financial intermediary may be subject to different rights of accumulation policies of such financial intermediary. Please consult with your financial professional for further details.

------

*Letter of Intent*. A Letter of Intent allows you to combine all purchases of any share class of any American Century Investments mutual fund you intend to make over a 13-month period to determine the applicable sales charge, except for purchases in the A or C Class of money market funds. At your request, existing holdings may be combined with new purchases and sales charge amounts may be adjusted for purchases made within 90 days prior to our receipt of the Letter of Intent. Capital appreciation, capital gains and reinvested dividends earned during the Letter of Intent period do not apply toward its completion. A portion of your account will be held in escrow to cover additional A Class sales charges that will be due if your total investments over the 13-month period do not qualify for the applicable sales charge reduction.

*Waivers for Certain Investors.* The sales charge on A Class shares may be waived for:

• Purchases by registered representatives and other employees of certain financial intermediaries (and their immediate family members, which includes their spouse or domestic partner and children or step-children, parents or step-parents of them, their spouse or domestic partner) having selling agreements with the advisor or distributor

• Broker-dealer sponsored wrap program accounts and/or fee-based accounts maintained for clients of certain financial intermediaries who have entered into selling agreements with American Century Investments

• Purchases in accounts of financial intermediaries that have entered into a selling agreement with American Century Investments that allows for the waiver of the sales charge in brokerage accounts that may or may not charge a transaction fee

• Current officers, directors or employees of American Century Investments

• Certain group employer-sponsored retirement plans, where plan level or omnibus accounts are held with the fund, or shares are purchased by certain retirement plans that are part of a retirement plan or platform offered by banks, broker-dealers, financial advisors or insurance companies, or serviced by retirement recordkeepers. For purposes of this waiver, employer-sponsored retirement plans do not include SEP IRAs, SIMPLE IRAs or SARSEPs. However, SEP IRA, SIMPLE IRA or SARSEP retirement plans that (i) held shares of an A Class fund prior to March 1, 2009 that received sales charge waivers or (ii) held shares of an Advisor Class fund that was renamed A Class on March 1, 2010, may permit additional purchases by new and existing participants in A Class shares without an initial sales charge. Refer to *Buying and Selling Fund Shares* in the statement of additional information

• Purchases of additional shares in accounts that held shares of an Advisor Class fund that was renamed A Class on either September 4, 2007, December 3, 2007 or March 1, 2010. However, if you close your account or if you transfer your account to another financial intermediary, future purchases of A Class shares of a fund may not receive a sales charge waiver.

An investor who receives a sales charge waiver for purchases of fund shares through a financial intermediary may become ineligible to receive such waiver if the nature of the investor's relationship with and/or the services it receives from the financial intermediary changes. Please consult with your financial professional for further details.

**C Class**

C Class shares are sold at their net asset value without an initial sales charge. If you purchase shares through a financial intermediary who receives a commission from the fund's distributor on the purchase and redeem your shares within 12 months of purchase, you will pay a CDSC of 1.00% of the original purchase price or the current market value at redemption, whichever is less. The purpose of the CDSC is to permit the fund's distributor to recoup all or a portion of the up-front payment made to your financial professional. There is no CDSC on shares acquired through reinvestment of dividends or capital gains.

American Century Investments generally limits purchases of C Class shares to investors whose aggregate investments in American Century Investments mutual funds are less than $1,000,000. However, it is your responsibility to inform your financial intermediary and/or American Century Investments at the time of purchase of any accounts to be aggregated, including investments in any share class of any American Century Investments mutual fund (excluding certain assets in money market accounts, but including account assets invested in Qualified Tuition Programs under Section 529) in accounts held by you and your immediate family members (which includes your spouse or domestic partner and children, step-children, parents or step-parents of you, your spouse or domestic partner). Once you reach this limit, you should work with your financial intermediary to determine what share class is most appropriate for additional purchases.

C Class shares automatically convert to A Class shares after being held for 8 years. The automatic conversion will be executed in the month following the 8-year anniversary of the purchase date for such C Class shares without any sales charge, fee or other charges. The conversion from C Class shares is not considered a taxable event for Federal income tax purposes. After the conversion, shares will be subject to all features and expenses of A Class shares.

**Calculation of Contingent Deferred Sales Charge (CDSC)** 

To minimize the amount of the CDSC you may pay when you redeem shares, the fund will first redeem shares acquired through reinvested dividends and capital gain distributions, which are not subject to a CDSC. Shares that have been in your account long enough that they are not subject to a CDSC are redeemed next. For any remaining redemption amount, shares will be sold in the order they were purchased (earliest to latest).

------

**CDSC Waivers**

Any applicable CDSC for A or C Classes may be waived in the following cases:

• redemptions through systematic withdrawal plans not exceeding annually 12% of the lesser of the original purchase cost or current market value for A and C Class shares

• redemptions through employer-sponsored retirement plans. For this purpose, employer-sponsored retirement plans do not include SEP IRAs, SIMPLE IRAs or SARSEPs.

• distributions from IRAs due to attainment of age 59½ for A Class shares and for C Class shares

• required minimum distributions from retirement accounts due to the shareholder reaching the qualified age based on applicable IRS regulations

• tax-free returns of excess contributions to IRAs

• redemptions due to death or post-purchase disability

• exchanges, unless the shares acquired by exchange are redeemed within the original CDSC period

• IRA Rollovers from any American Century Investments mutual fund held in an employer-sponsored retirement plan, for A Class shares only

• if no dealer commission was paid to the financial intermediary on the purchase for any other reason

**Reinstatement Privilege**

Within 90 days of a redemption, dividend payment or capital gains distribution of any A Class shares, you may reinvest all or a portion of the proceeds in A Class shares of any American Century Investments mutual fund at the then-current net asset value without paying an initial sales charge. At your request, any CDSC you paid on an A Class redemption that you are reinvesting will be credited to your account. You may use the privilege only once per account. This privilege may only be invoked by the original account owner to reinvest shares in an account with the same registration as the account from which the redemption or distribution originated. This privilege does not apply to systematic or automatic transactions, including, for example, automatic purchases, withdrawals and payroll deductions. If you wish to use this reinvestment privilege, you or your financial professional must provide written notice to American Century Investments.

**Employer-Sponsored Retirement Plans**

Certain group employer-sponsored retirement plans that hold a single account for all plan participants with the fund, or that are part of a retirement plan or platform offered by banks, broker-dealers, financial advisors or insurance companies, or serviced by retirement recordkeepers are eligible to purchase Investor, I, A, C, R and R6 Class shares. For more information regarding employer-sponsored retirement plan types, please refer to *Buying and Selling Fund Shares* in the statement of additional information. A and C Class purchases are available at net asset value with no dealer commission paid to the financial professional, and do not incur a CDSC. A, C and R Class shares purchased in employer-sponsored retirement plans are subject to applicable distribution and service (12b-1) fees, which the financial intermediary begins receiving immediately at the time of purchase. American Century does not impose plan size or participant number requirements by class for employer-sponsored retirement plans; however, financial intermediaries or plan recordkeepers may require plans to meet different requirements.

**Exchanging Shares**

You may exchange shares of the fund for shares of the same class of another American Century Investments mutual fund without a sales charge if you meet the following criteria:

• The exchange is for a minimum of $100

• For an exchange that opens a new account, the amount of the exchange must meet or exceed the minimum account size requirement for the fund receiving the exchange

For purposes of computing any applicable CDSC on shares that have been exchanged, the holding period will begin as of the date of purchase of the original fund owned. Exchanges from a money market fund are subject to a sales charge on the fund being purchased, unless the money market fund shares were acquired by exchange from a fund with a sales charge or by reinvestment of dividends or capital gains distributions.

**Moving Between Share Classes and Accounts**

You may move your investment between share classes (within the same fund or between different funds) in certain circumstances deemed appropriate by American Century Investments. You also may move investments held in certain accounts to a different type of account if you meet certain criteria. Please contact your financial professional for more information about moving between share classes or account types.

------

**Buying and Selling Shares Through a Financial Intermediary**

Your ability to purchase, exchange, redeem and transfer shares will be affected by the policies of the financial intermediary through which you do business. Some policy differences may include

• minimum investment requirements

• exchange policies

• fund choices

• cutoff time for investments

• trading restrictions

In addition, your financial intermediary may charge a transaction fee for the purchase or sale of fund shares. Those charges are retained by the financial intermediary and are not shared with American Century Investments or the funds. Please contact your financial intermediary or plan sponsor for a complete description of its policies. Copies of the funds' annual report, semiannual report and statement of additional information are available from your financial intermediary or plan sponsor.

The funds have authorized certain financial intermediaries to accept orders on the funds' behalf. American Century Investments has selling agreements with these financial intermediaries requiring them to track the time investment orders are received and to comply with procedures relating to the transmission of orders. Orders must be received by the financial intermediary on the funds' behalf before the time the net asset value is determined in order to receive that day's share price. If those orders are transmitted to American Century Investments and paid for in accordance with the selling agreement, they will be priced at the net asset value next determined after your request is received in the form required by the financial intermediary.

If you submit a transaction request through a financial intermediary that does not have a selling agreement with us, or if the financial intermediary's selling agreement does not cover the type of account or share class requested, we may reject or cancel the transaction without prior notice to you or the intermediary.

Investor and I Class shares may also be available on brokerage platforms of financial intermediaries that have agreements with American Century Investments to offer such shares solely when acting as an agent for the shareholder. A shareholder transacting in Investor or I Class shares in these programs may be required to pay a commission and/or other forms of compensation to the broker. Shares of the fund are available in other share classes that have different fees and expenses.

**See *Additional Policies Affecting Your Investment* for more information about investing with us.**

**Additional Policies Affecting Your Investment**

**Eligibility for Investor Class Shares**

The fund's Investor Class shares are available for purchase directly from American Century Investments and through the following types of products, programs or accounts offered by financial intermediaries:

• self-directed accounts on transaction-based platforms that may or may not charge a transaction fee

• employer-sponsored retirement plans

• broker-dealer sponsored fee-based wrap programs or other fee-based advisory accounts

• insurance products and bank/trust products where fees are being charged

The fund reserves the right, when in the judgment of American Century Investments it is not adverse to the fund's interest, to permit all or only certain types of investors to open new accounts in the fund, to impose further restrictions, or to close the fund to any additional investments, all without notice.

**Minimum Initial Investment Amounts for Investor, A, C and R Classes**

Unless otherwise specified below, the minimum initial investment amount to open an account is $2,500. However, American Century Investments will waive the fund minimum if you make an initial investment of at least $500 and continue to make automatic investments of at least $100 a month until reaching the fund minimum.

Investors opening accounts through financial intermediaries may open an account with $250, but the financial intermediaries may require their clients to meet different investment minimums. See *Investing Through a Financial Intermediary* for more information.

<sup>1</sup> *&nbsp;&nbsp;&nbsp;&nbsp;American Century Investments will waive the minimum if you make an initial investment of at least $500 and continue to make automatic investments of at least $100 a month until reaching the minimum.*

<sup>2</sup> *&nbsp;&nbsp;&nbsp;&nbsp;The minimum initial investment for shareholders investing through financial intermediaries is $250. Financial intermediaries may have different minimums for their clients.*

**Subsequent Purchases**

There is a $50 minimum for subsequent purchases. See *Ways to Manage Your Account* for more information about making additional investments directly with American Century Investments. However, there is no subsequent purchase minimum for financial intermediaries or employer-sponsored retirement plans, but financial intermediaries may require their clients to meet different subsequent purchase requirements.

**Eligibility for I Class Shares**

I Class shares are made available for purchase by individuals and large institutional shareholders such as bank trust departments, corporations, retirement plans, endowments, foundations and financial advisors that meet the funds' minimum investment requirements.

**Minimum Initial Investment Amounts for I Class**

The minimum initial investment amount for I Class shares is generally $5 million ($3 million for endowments and foundations) per fund. If you invest with us through a financial intermediary, this requirement may be met if your financial intermediary aggregates your investments with those of other clients into a single group, or omnibus, account that meets the minimum. The minimum investment requirement may be waived if you have an aggregate investment in the American Century family of funds of $10 million or more ($5 million for endowments and foundations). This includes accounts held directly with American Century and those held through a financial intermediary. American Century Investments also may waive the minimum initial investment in other situations it deems appropriate. In addition, there is no minimum investment amount for employer-sponsored retirement plans where a financial intermediary provides retirement recordkeeping services to plan participants and where plan level or omnibus accounts are held on the books of the fund. Financial intermediaries or plan recordkeepers may require plans to meet certain other conditions, such as plan size or minimum level of assets per participants, in order to be eligible to purchase I Class shares.

American Century Investments may permit an intermediary to waive the initial minimum per shareholder as provided in *Buying and Selling Fund Shares* in the statement of additional information.

------

**Eligibility for R6 Class Shares** 

The fund's R6 Class shares are generally available only through employer-sponsored retirement plans where a financial intermediary provides retirement recordkeeping services to plan participants. To be eligible, plan level or omnibus accounts must be held on the books of the fund.

R6 Class shares are not available to retail accounts, traditional or Roth IRAs, SEP IRAs, SIMPLE IRAs, SARSEPs or Coverdell education savings accounts.

**Minimum Initial Investment Amounts for R6 Class**

There is no minimum initial amount or subsequent investment amount for R6 Class shares, but financial intermediaries or plan recordkeepers may require plans to meet different investment minimums.

**Redemptions**

Your redemption proceeds will be calculated using the net asset value (NAV) next determined after we receive your transaction request in good order. If you sell C or, in certain cases, A Class shares, you may pay a sales charge, depending on how long you have held your shares, as described above.

Generally, we expect to remit your redemption proceeds to you one business day after we process your transaction. However, we reserve the right to delay delivery of redemption proceeds for up to seven days. For example, each time you make an investment with American Century Investments, there is a seven-day holding period before we will release redemption proceeds from those shares, unless you provide us with satisfactory proof that your purchase funds have cleared. Investments by wire generally require only a one-day holding period. If you change your address, we may require that any redemption request made within seven days be submitted in writing and be signed by all authorized signers with their signatures guaranteed. We may also require a signature guarantee for redemptions in other situations, as described below. If you change your bank information, we may impose a seven-day holding period before we will transfer or wire redemption proceeds to your bank. Please remember, if you request redemptions by wire, $10 will be deducted from the amount redeemed. Your bank also may charge a fee.

Under normal market conditions, the fund generally meets redemption requests through its holdings of cash or cash equivalents or by selling portfolio securities. However, we reserve the right to honor certain redemptions with securities, rather than cash, as described in the next section. Additionally, the fund may consider interfund lending to meet redemption requests. The fund is more likely to use these other methods to meet large redemption requests or during times of market stress.

Additionally, if you are age 65 or older, or if we have reason to believe you have a mental or physical impairment that renders you unable to protect your own interest, we may temporarily delay the disbursement of redemption proceeds from your account if we believe that you have been the victim of actual or attempted financial exploitation. This temporary delay will be for an initial period of no more than 15 business days while we conduct an internal review of the facts and circumstances of the suspected financial exploitation. If our internal review supports our belief that actual or attempted financial exploitation has occurred or is occurring, we may extend the hold for up to 10 additional business days. At the expiration of the additional hold time, if we have not confirmed that exploitation has occurred, the proceeds will be released to you.

**Redemption of Shares in Accounts Below Minimum**

If your account balance falls below the minimum initial investment amount for any reason, or if you cancel your automatic monthly investment plan prior to reaching the fund minimum, American Century Investments reserves the right to redeem the shares in the account and send the proceeds to your address of record. Prior to doing so, we will notify you and give you 60 days to meet the minimum or reinstate your automatic monthly investment plan. Please note that A and C Class shares redeemed in this manner may be subject to a sales charge if held less than the applicable time period. You also may incur tax liability as a result of the redemption. For I Class shares, we reserve the right to convert your shares to Investor Class shares of the same fund. The total annual operating expenses of Investor Class shares are higher than I Class shares.

**Small Distributions and Uncashed Distribution Checks**

Generally, dividends and distributions cannot be paid by check for an amount less than $50. Any such amount will be automatically reinvested in additional shares. The fund reserves the right to reinvest any dividend or distribution amount you elect to receive by check if your check is returned as undeliverable or if you do not cash your check within six months. Interest will not accrue on the amount of your uncashed check. We will reinvest your check into your account at the NAV on the day of reinvestment. When reinvested, those amounts are subject to the risk of loss like any other fund investment. We also reserve the right to change your election to receive dividends and distributions in cash after a check is returned undeliverable or uncashed for the six month period, and we may automatically reinvest all future dividends and distributions at the NAV on the date of the payment.

------

**Signature Guarantees**

A signature guarantee — which is different from a notarized signature — is a warranty that the signature presented is genuine. We may require a signature guarantee for the following transactions:

• Your redemption or distribution check or automatic redemption is made payable to someone other than the account owners;

• Your redemption proceeds or distribution amount is sent by EFT (ACH or wire) to a destination other than your personal bank account;

• You are transferring ownership of an account over $100,000;

• You change your address and request a redemption over $100,000 within seven days;

• You request proceeds from redemptions, dividends, or distributions be sent to an address or financial institution differing from those on record; or

• You make a redemption or other transaction request via telephone, and we are unable to verify your identity.

We reserve the right to require a signature guarantee for other transactions, or we may employ other security measures, such as signature comparison or notarized signature, at our discretion.

**Canceling a Transaction**

American Century Investments will use its best efforts to honor your request to revoke a transaction instruction if your revocation request is received prior to the close of trading on the New York Stock Exchange (NYSE) (generally 4 p.m. Eastern time) on the trade date of the transaction. Once processing has begun, or the NYSE has closed on the trade date, the transaction can no longer be canceled. Each fund reserves the right to suspend the offering of shares for a period of time and to reject any specific investment (including a purchase by exchange). Additionally, we may refuse a purchase if, in our judgment, it is of a size that would disrupt the management of a fund.

**Frequent Trading Practices**

Because of the potentially harmful effects of abusive trading practices, the funds' Board of Directors has approved American Century Investments' abusive trading policies and procedures, which are designed to reduce the frequency and effect of these activities in our funds. These policies and procedures include monitoring trading activity, imposing trading restrictions on certain accounts, and using fair value pricing when current market prices are not readily available for securities held by the underlying funds. Although these efforts are designed to discourage abusive trading practices, they cannot eliminate the possibility that such activity will occur. American Century Investments seeks to exercise its judgment in implementing these tools to the best of its ability in a manner that it believes is consistent with shareholder interests.

American Century Investments uses a variety of techniques to monitor for and detect frequent trading practices. These techniques may vary depending on the type of fund, the class of shares or whether the shares are held directly or indirectly with American Century Investments. They may change from time to time as determined by American Century Investments in its sole discretion. To minimize harm to the funds and their shareholders, we reserve the right to reject any purchase order (including exchanges) from any shareholder we believe has a history of frequent trading or whose trading, in our judgment, has been or may be disruptive to the funds. In making this judgment, we may consider trading done in multiple accounts under common ownership or control.

Currently, for shares held directly with American Century Investments, we may deem the sale of all or a substantial portion of a shareholder's purchase of fund shares to be frequent trading if the sale is made

• within seven days of the purchase, or

• within 30 days of the purchase, if it happens more than once per year.

To the extent practicable, we try to use the same approach for defining frequent trading for shares held through financial intermediaries. American Century Investments reserves the right, in its sole discretion, to identify other trading practices as abusive and to modify its monitoring and other practices as necessary to deal with novel or unique abusive trading practices.

------

The frequent trading limitations do not apply to the following types of transactions:

• purchases of shares through reinvested distributions (dividends and capital gains);

• redemption of shares to pay fund or account fees;

• CheckWriting redemptions;

• redemptions requested following the death of a registered shareholder;

• transactions through automatic purchase or redemption plans;

• transfers and re-registrations of shares within the same fund;

• shares exchanged from one share class to another within the same fund;

• transactions by 529 college savings plans; and

• reallocation or rebalancing transactions in broker-dealer sponsored fee-based wrap and advisory programs.

For shares held in employer-sponsored retirement plans, generally only participant-directed exchange transactions are subject to the frequent trading restrictions. For this purpose, employer-sponsored retirement plans do not include SEP IRAs, SIMPLE IRAs, or SARSEPs.

In addition, American Century Investments reserves the right to accept purchases and exchanges in excess of the trading restrictions discussed above if it believes that such transactions would not be inconsistent with the best interests of fund shareholders or this policy.

American Century Investments' policies do not permit us to enter into arrangements with fund shareholders that permit such shareholders to engage in frequent purchases and redemptions of fund shares. Due to the complexity and subjectivity involved in identifying abusive trading activity and the volume of shareholder transactions American Century Investments handles, there can be no assurance that American Century Investments' efforts will identify all trades or trading practices that may be considered abusive. American Century Investments monitors aggregate trades placed in omnibus accounts and works with financial intermediaries to identify shareholders engaging in abusive trading practices and impose restrictions to discourage such practices. Because American Century Investments relies on financial intermediaries to provide information and impose restrictions, our ability to monitor and discourage abusive trading practices in omnibus accounts may be dependent upon the intermediaries' timely performance of such duties and restrictions may not be applied uniformly in all cases.

**Your Responsibility for Unauthorized Transactions**

American Century Investments and its affiliated companies use procedures reasonably designed to confirm that telephone, electronic and other instructions are genuine. These procedures include recording telephone calls, requesting additional identifying information, requiring personalized security codes or other information online, and sending confirmation of transactions. If we follow these procedures, we are not responsible for any losses that may occur due to unauthorized instructions. For transactions conducted over the Internet, we recommend the use of a secure Internet browser. In addition, you should verify the accuracy of your confirmation statements immediately after you receive them.

**A Note About Mailings to Shareholders**

To reduce the amount of mail you receive from us, we generally deliver a single copy of fund documents (like shareholder reports, proxies and prospectuses) to investors who share an address, even if their accounts are registered under different names. Investors who share an address may also receive account-specific documents (like statements) in a single envelope. If you prefer to receive your documents addressed individually, please call us or your financial professional. For American Century Investments brokerage accounts, please call 1-888-345-2071.

**Right to Change Policies**

We reserve the right to change any stated investment requirement, including those that relate to purchases, exchanges and redemptions. In accordance with applicable law, we also may alter, add or discontinue any service or privilege. Changes may affect all investors or only those in certain classes or groups. In addition, from time to time we may waive a policy on a case-by-case basis, as the advisor deems appropriate.

------

**Share Price and Distributions**

**Share Price**

American Century Investments will price the fund shares you purchase, exchange or redeem based on the ***net asset value*** (NAV) next determined after your order is received in good order by the fund's transfer agent, or other financial intermediary with the authority to accept orders on the fund's behalf. We determine the NAV of each fund as of the close of regular trading (usually 4 p.m. Eastern time) on the New York Stock Exchange (NYSE) on each day the NYSE is open. On days when the NYSE is closed (including certain U.S. national holidays), we do not calculate the NAV.

*The* ***net asset value****, or NAV, of each class of a fund is the current value of the class's assets, minus any liabilities, divided by the number of shares of the class outstanding.* <br>

Each fund's NAV is calculated based upon the NAVs of the underlying funds in which the fund invests. The prospectuses for the underlying funds explain the methods used to value underlying fund shares, including the circumstances under which those funds may use fair value pricing and the effects of doing so.

Trading in foreign markets of securities that are held by the underlying funds may not take place every day the NYSE is open. Also, trading in some foreign markets and on some electronic trading networks may take place on weekends or holidays when the underlying funds' NAVs are not calculated. So, the value of the underlying funds' portfolios and consequently the funds' portfolios may be affected on days when you will not be able to purchase, exchange or redeem fund shares.

**Distributions**

Federal tax laws require each fund to make distributions to its shareholders in order to qualify as a regulated investment company. Qualification as a regulated investment company means that the funds should not be subject to state or federal income tax on amounts distributed. The distributions generally consist of dividends and interest received by the fund, as well as ***capital gains*** realized by the fund on the sale of its investment securities.

***Capital gains*** *are increases in the values of capital assets, such as stocks or bonds, from the time the assets are purchased.*<br>

Distributions of substantially all of its income is paid quarterly for One Choice In Retirement Portfolio and annually for One Choice 2030 Portfolio, One Choice 2035 Portfolio, One Choice 2040 Portfolio, One Choice 2045 Portfolio, One Choice 2050 Portfolio, One Choice 2055 Portfolio, One Choice 2060 Portfolio, One Choice 2065 Portfolio and One Choice 2070 Portfolio. Distributions from realized capital gains for all the funds are generally paid annually, usually in December. The funds may make more frequent distributions, if necessary, to comply with Internal Revenue Code provisions.

You will participate in fund distributions when they are declared, starting the next business day after your purchase is effective. For example, if you purchase shares on a day that a distribution is declared, you will not receive that distribution. If you redeem shares, you will receive any distribution declared on the day you redeem. If you redeem all shares, we will include any distributions received with your redemption proceeds.

Generally, participants in tax-deferred retirement plans reinvest all distributions. For investors investing through taxable accounts, we will reinvest distributions unless you elect to have dividends and/or capital gains sent to another American Century Investments account, to your bank electronically, or to your home address or to another person or address by check.

------

**Taxes**

Some of the tax consequences of owning shares of the funds will vary depending on whether you own them through a taxable or tax-deferred account. Distributions by the funds of dividend and interest income, capital gains and other income they have generated through their investment activities, will generally be taxable to shareholders who hold shares in a taxable account. Tax consequences also may result when investors sell fund shares after the net asset value has increased or decreased.

**Tax-Deferred Accounts**

If you purchase fund shares through a tax-deferred account, such as an IRA or employer-sponsored retirement plan, income and capital gains distributions usually will not be subject to current taxation but will accumulate in your account under the plan on a tax-deferred basis. Likewise, moving from one fund to another fund within a plan or tax-deferred account generally will not cause you to be taxed. For information about the tax consequences of making purchases or withdrawals through a tax-deferred account, please consult your plan administrator, your summary plan description or a tax advisor.

**Taxable Accounts**

If you own fund shares through a taxable account, you may be taxed on your investments if the fund makes distributions or if you sell your fund shares.

**Taxability of Distributions**

Fund distributions may consist of income, such as dividends and interest earned by a fund from its investments, or capital gains generated by a fund from the sale of investment securities. Distributions of income are taxed as ordinary income, unless they are designated as ***qualified dividend income*** and you meet a minimum required holding period with respect to your shares of the fund, in which case distributions of income are taxed at the same rates as long-term capital gains.

***Qualified dividend income*** *is a dividend received by the fund from the stock of a domestic or qualifying foreign corporation, provided that the fund has held the stock for a required holding period and the stock was not on loan at the time of the dividend.*<br>

The tax character of any distributions from capital gains is determined by how long the fund held the underlying security that was sold, not by how long you have been invested in the fund or whether you reinvest your distributions or take them in cash. Short-term (one year or less) capital gains are taxable as ordinary income. Gains on securities held for more than one year are taxed at the lower rates applicable to long-term capital gains.

If the fund's distributions exceed current and accumulated earnings and profits, such excess will generally be considered a return of capital. A return of capital distribution is generally not subject to tax, but will reduce your cost basis in the fund and result in higher realized capital gains (or lower realized capital losses) upon the sale of fund shares.

For taxable accounts, American Century Investments or your financial intermediary will inform you of the tax character of fund distributions for each calendar year in an annual tax mailing.

If you meet specified income levels, you will also be subject to a 3.8% Medicare contribution tax which is imposed on net investment income, including interest, dividends and capital gains. Distributions also may be subject to state and local taxes. Because everyone's tax situation is unique, you may want to consult your tax professional about federal, state and local tax consequences.

**Taxes on Transactions** 

Your redemptions—including exchanges to other American Century Investments mutual funds—are subject to capital gains tax. Short-term capital gains are gains on fund shares you held for 12 months or less. Long-term capital gains are gains on fund shares you held for more than 12 months. If your shares decrease in value, their sale or exchange will result in a long-term or short-term capital loss. However, you should note that loss realized upon the sale or exchange of shares held for six months or less will be treated as a long-term capital loss to the extent of any distribution of long-term capital gain to you with respect to those shares. If a loss is realized on the redemption of fund shares, the reinvestment in additional fund shares within 30 days before or after the redemption may be subject to the wash sale rules of the Internal Revenue Code. This may result in a postponement of the recognition of such loss for federal income tax purposes.

If you have not certified to us that your Social Security number or tax identification number is correct and that you are not subject to withholding, we are required to withhold and pay to the IRS the applicable federal withholding tax rate on taxable dividends, capital gains distributions and redemption proceeds.

------

**Buying a Dividend** 

Purchasing fund shares in a taxable account shortly before a distribution is sometimes known as buying a dividend. In taxable accounts, you must pay income taxes on the distribution whether you reinvest the distribution or take it in cash. In addition, you will have to pay taxes on the distribution whether the value of your investment decreased, increased or remained the same after you bought the fund shares.

The risk in buying a dividend is that a fund's portfolio may build up taxable income and gains throughout the period covered by a distribution, as income is earned and securities are sold at a profit. The fund distributes the income and gains to you, after subtracting any losses, even if you did not own the shares when the income was earned or the gains occurred.

If you buy a dividend, you incur the full tax liability of the distribution period, but you may not enjoy the full benefit of the income earned or the gains realized in the fund's portfolio.

------

**Multiple Class Information**

The funds offer multiple classes of shares. The classes have different fees, expenses and/or minimum investment requirements. Different fees and expenses will affect performance.

Except as described below, all classes of shares of each fund have identical voting, dividend, liquidation and other rights, preferences, terms and conditions. The only differences among the classes are (a) each class may be subject to different expenses specific to that class; (b) each class has a different identifying designation or name; (c) each class has exclusive voting rights with respect to matters solely affecting such class; (d) each class may have different exchange privileges; (e) the I Class may provide for conversion from that class into shares of the Investor Class of the same fund; and (f) the C Class provides for automatic conversion from that class into shares of the A Class of the same fund after 8 years.

**Service, Distribution and Administrative Fees** 

Investment Company Act Rule 12b-1 permits mutual funds that adopt a written plan to pay certain expenses associated with the distribution of their shares out of fund assets. Each class, except the Investor Class, I Class and R6 Class, offered by this prospectus has a 12b-1 plan. The plans provide for the funds to pay annual fees of 0.25% for A Class, 1.00% for C Class and 0.50% for R Class to the distributor, for distribution and individual shareholder services, including past distribution services. The distributor pays all or a portion of such fees to the financial intermediaries that make the classes available. Because these fees may be used to pay for services that are not related to prospective sales of the funds, each class will continue to make payments under its plan even if it is closed to new investors. Because these fees are paid out of the funds' assets on an ongoing basis, over time these fees will increase the cost of your investment and may cost you more than paying other types of sales charges. The higher fees for C Class shares may cost you more over time than paying the initial sales charge for A Class shares. For additional information about the plans and their terms, see *Multiple Class Structure* in the statement of additional information.

Certain financial intermediaries perform recordkeeping and administrative services for their clients that would otherwise be performed by American Century Investments' transfer agent. In some circumstances, the advisor will pay such service providers a fee for performing those services. Also, the advisor and the funds' distributor may make payments to intermediaries for various additional services, other expenses and/or the intermediaries' distribution of the fund out of their profits or other available sources. Such payments may be made for one or more of the following: (1) distribution, which may include expenses incurred by intermediaries for their sales activities with respect to the funds, such as preparing, printing and distributing sales literature and advertising materials and compensating registered representatives or other employees of such financial intermediaries for their sales activities, as well as the opportunity for the fund to be made available by such intermediaries; (2) shareholder services, such as providing individual and custom investment advisory services to clients of the financial intermediaries; and (3) marketing and promotional services, including business planning assistance, educating personnel about the funds, and sponsorship of sales meetings, which may include covering costs of providing speakers, meals and other entertainment. The distributor may pay partnership and/or sponsorship fees to support seminars, conferences, and other programs designed to educate intermediaries about the funds and may cover the expenses associated with attendance at such meetings, including travel costs. The distributor also may pay fees related to obtaining data regarding intermediary or financial advisor activities to assist American Century Investments with sales reporting, business intelligence, and training and education opportunities. These payments may create a conflict of interest by influencing the intermediary to recommend the funds over another investment. Ask your salesperson or visit your financial intermediary's website for more information. The amount of any payments described by this paragraph is determined by the advisor or the distributor, and all such amounts are paid out of their available assets, and not paid by you or the funds. As a result, the total expense ratio of the funds will not be affected by any such payments.

American Century Investments does not pay any fees to financial intermediaries on R6 Class shares.

**Financial Highlights**

**Understanding the Financial Highlights** 

The tables on the next few pages itemize what contributed to the changes in share price during the most recently ended fiscal period. They also show the changes in share price for this period in comparison to changes over the last five fiscal years (or a shorter period if the share class is not five years old).

On a per-share basis, each table includes as appropriate

• share price at the beginning of the period

• investment income and capital gains or losses

• distributions of income and capital gains paid to investors

• share price at the end of the period

Each table also includes some key statistics for the period as appropriate

• **Total Return** – the overall percentage of return of the fund, assuming the reinvestment of all distributions

• **Expense Ratio** – the operating expenses of the fund as a percentage of average net assets

**• Net Income Ratio** – the net investment income of the fund as a percentage of average net assets

**• Portfolio Turnover** – the percentage of the fund's investment portfolio that is replaced during the period

The Financial Highlights that follow have been audited by Deloitte & Touche LLP. Their Report of Independent Registered Public Accounting Firm and the financial statements and financial highlights are included in the funds' Form N-CSR, which is available upon request.

**Appendix A**

The information in this Appendix is part of, and incorporated into, the fund's prospectus.

**Financial Intermediary Sales Charge Reduction and Waiver Information**

The availability of certain sales charge waivers and discounts will depend on whether you purchase your shares directly from the fund or through a financial intermediary. Intermediaries may have different policies and procedures regarding the availability of front-end sales load waivers or contingent deferred (back-end) sales load (CDSC) waivers, which are set forth below. In all instances, it is the investor's responsibility to notify the fund or the applicable financial intermediary at the time of purchase of any relationship or other facts qualifying the investor for sales charge waivers or discounts. **For waivers and discounts not available through a particular intermediary, shareholders will have to purchase fund shares directly from the fund or through another intermediary to receive these waivers or discounts.**

**Policies Regarding Transactions Through Edward D. Jones & Co., L.P. ("Edward Jones")**

The following information has been provided by Edward Jones:

Effective on or after September 3, 2024, the following information supersedes prior information with respect to transactions and positions held in fund shares through an Edward Jones system. Clients of Edward Jones (also referred to as "shareholders") purchasing fund shares on the Edward Jones commission and fee-based platforms are eligible only for the following sales charge discounts (also referred to as "breakpoints") and waivers, which can differ from discounts and waivers described elsewhere in the mutual fund prospectus or statement of additional information ("SAI") or through another broker-dealer. In all instances, it is the shareholder's responsibility to inform Edward Jones at the time of purchase of any relationship, holdings of American Century, or other facts qualifying the purchaser for discounts or waivers. Edward Jones can ask for documentation of such circumstance. Shareholders should contact Edward Jones if they have questions regarding their eligibility for these discounts and waivers.

**Breakpoints**

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• Breakpoint pricing, otherwise known as volume pricing, at dollar thresholds as described in the prospectus.

------

**Rights of Accumulation ("ROA")**

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• The applicable sales charge on a purchase of Class A shares is determined by taking into account all share classes (except certain money market funds and any assets held in group retirement plans) of American Century held by the shareholder or in an account grouped by Edward Jones with other accounts for the purpose of providing certain pricing considerations ("pricing groups"). If grouping assets as a shareholder, this includes all share classes held on the Edward Jones platform and/or held on another platform. The inclusion of eligible fund family assets in the ROA calculation is dependent on the shareholder notifying Edward Jones of such assets at the time of calculation. Money market funds are included only if such shares were sold with a sales charge at the time of purchase or acquired in exchange for shares purchased with a sales charge.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• The employer maintaining a SEP IRA plan and/or SIMPLE IRA plan may elect to establish or change ROA for the IRA accounts associated with the plan to a plan-level grouping as opposed to including all share classes at a shareholder or pricing group level.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• ROA is determined by calculating the higher of cost minus redemptions or market value (current shares x NAV).

**Letter of Intent ("LOI")**

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• Through a LOI, shareholders can receive the sales charge and breakpoint discounts for purchases shareholders intend to make over a 13-month period from the date Edward Jones receives the LOI. The LOI is determined by calculating the higher of cost or market value of qualifying holdings at LOI initiation in combination with the value that the shareholder intends to buy over a 13-month period to calculate the front-end sales charge and any breakpoint discounts. Each purchase the shareholder makes during that 13-month period will receive the sales charge and breakpoint discount that applies to the total amount. The inclusion of eligible fund family assets in the LOI calculation is dependent on the shareholder notifying Edward Jones of such assets at the time of calculation. Purchases made before the LOI is received by Edward Jones are not adjusted under the LOI and will not reduce the sales charge previously paid. Sales charges will be adjusted if LOI is not met.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• If the employer maintaining a SEP IRA plan and/or SIMPLE IRA plan has elected to establish or change ROA for the IRA accounts associated with the plan to a plan-level grouping, LOIs will also be at the plan-level and may only be established by the employer.

**Sales Charge Waivers**

Sales charges are waived for the following shareholders and in the following situations:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• Associates of Edward Jones and its affiliates and other accounts in the same pricing group (as determined by Edward Jones under its policies and procedures) as the associate. This waiver will continue for the remainder of the associate's life if the associate retires from Edward Jones in good-standing and remains in good standing pursuant to Edward Jones' policies and procedures.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• Shares purchased in an Edward Jones fee-based program.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• Shares purchased through reinvestment of capital gains distributions and dividend reinvestment.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• Shares purchased from the proceeds of redeemed shares of the same fund family so long as the following conditions are met: the proceeds are from the sale of shares within 60 days of the purchase, the sale and purchase are made from a share class that charges a front load and one of the following ("Right of Reinstatement"):

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• The redemption and repurchase occur in the same account.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• The redemption proceeds are used to process an: IRA contribution, excess contributions, conversion, recharacterizing of contributions, or distribution, and the repurchase is done in an account within the same Edward Jones grouping for ROA.

The Right of Reinstatement excludes systematic or automatic transactions including, but not limited to, purchases made through payroll deductions, liquidations to cover account fees, and reinvestments from non-mutual fund products.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• Shares exchanged into Class A shares from another share class so long as the exchange is into the same fund and was initiated at the discretion of Edward Jones. Edward Jones is responsible for any remaining CDSC due to the fund company, if applicable. Any future purchases are subject to the applicable sales charge as disclosed in the prospectus.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• Exchanges from Class C shares to Class A shares of the same fund, generally, in the 84th month following the anniversary of the purchase date or earlier at the discretion of Edward Jones.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• Purchases of Class 529-A shares made for recontribution of refunded amounts.

------

**Contingent Deferred Sales Charge ("CDSC") Waivers**

If the shareholder purchases shares that are subject to a CDSC and those shares are redeemed before the CDSC is expired, the shareholder is responsible to pay the CDSC except in the following conditions:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• The death or disability of the shareholder.

Any SEP IRA plan, any SIMPLE IRA plan or any Payroll Deduction plan ("PDP") on the PSS platform will be defaulted to plan-level grouping for purposes of ROA, which allows each participating employee ROA with all other eligible shares held in plan accounts on the PSS platform. At any time, a participating employee may elect to exercise a one-time option to change grouping for purposes of ROA to shareholder- level grouping, which allows the plan account of the electing employee ROA with her other eligible holdings on the PSS platform, but not with all other eligible participant holdings in the plan. Eligible shares held in plan accounts electing shareholder-level grouping will not be available for purposes of ROA to plan accounts electing plan-level grouping.

ROA is determined by calculating the higher of cost minus redemptions or current market value (current shares x NAV).

**Letter of Intent ("LOI")** 

By executing a LOI, shareholders can receive the sales charge and breakpoint discounts for purchases shareholders intend to make over a 13-month period through PFSI, from the date PSS receives the LOI. The purchase price of the LOI is determined by calculating the higher of cost or market value of qualifying holdings at LOI initiation in combination with the dollar amount the shareholder intends to invest over a 13-month period to arrive at total investment for purposes of determining any breakpoint discount and the applicable front-end sales charge. Each purchase the shareholder makes during that 13-month period will receive the sales charge and breakpoint discount that applies to the projected total investment.

Only holdings of American Century Funds on the PSS platform are eligible for inclusion in the LOI calculation and the shareholder must notify PFSI of all eligible assets at the time of calculation. It is the shareholder's responsibility to inform PFSI at the time of a purchase of all holdings of American Century Funds on the PSS platform, or other facts qualifying the purchaser for this discount.

Purchases made before the LOI is received by PSS are not adjusted under the LOI, and the LOI will not reduce any sales charge previously paid. Sales charges will be automatically adjusted if the total purchases required by the LOI are not met.

If an employer maintaining a SEP IRA plan, SIMPLE IRA plan or non-IRA PDP on the PSS platform has elected to establish or change ROA for the accounts associated with the plan to a plan-level grouping, LOIs will also be at the plan-level and may only be established by the employer. LOIs are not available to PDP IRA plans on the PSS platform with plan-level grouping for purposes of ROA, but are available to any participating employee that elects shareholder-level grouping for purposes of ROA.

**Sales Charge Waivers** 

Sales charges are waived for the following shareholders and in the following situations:

Shares purchased through reinvestment of capital gains distributions and dividend reinvestment.

Shares purchased with the proceeds of redeemed shares of the same fund family so long as the following conditions are met: 1) the proceeds are from the sale of shares within 90 days of the purchase, 2) the sale and purchase are made in the same share class and the same account or the purchase is made in an individual retirement account with proceeds from liquidations in a non-retirement account, and 3) the redeemed shares were subject to a front-end or deferred sales load, Automated transactions (i.e. systematic purchases and withdrawals), full or partial transfers or rollovers of retirement accounts, and purchases made after shares are automatically sold to pay account maintenance fees are not eligible for this sales charge waiver.

Shares exchanged into Class A shares from another share class so long as the exchange is into the same fund and was initiated at the discretion of PFSI. PFSI is responsible for any remaining CDSC due to the fund company, if applicable. Any future purchases are subject to the applicable sales charge as disclosed in the prospectus.

**Policies Regarding Fund Purchases Through PFSI That Are Not Held on the PSS Platform** 

Class R shares are available through PFSI only in 401(k) plans covering a business owner with no employees, commonly referred to as a one-participant 401(k) plan or solo 401(k).

PFSI may request reasonable documentation of facts qualifying the purchaser for the discounts and waivers identified above, and condition the granting of any discount or waiver on the timely receipt of such documents. Shareholders should contact PSS if they have questions regarding their eligibility for these discounts and waivers.

<sup>1</sup> *Purchases of $1 million or more may be subject to a contingent deferred sales charge of 1.00% if the shares are redeemed within one year of the date of the purchase.*

<sup>2</sup>*&nbsp;&nbsp;&nbsp;&nbsp;The advisor will waive a portion of the fund's management fee equal to the expenses attributable to the management fees of American Century-advised underlying funds. The amount of this waiver will fluctuate depending on the fund's daily allocations to such funds. This waiver is expected to remain in effect permanently, and it cannot be terminated without the approval of the Board of Directors.*

**Example**

The example below is intended to help you compare the costs of investing in the fund with the costs 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 all of your shares at the end of those periods, and that you earn a 5% return each year. The example also assumes that the fund's operating expenses remain the same except that it reflects the rate and duration of any fee waivers noted in the table above. 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* |
| Investor Class | $61 | $193 | $335 | $751 |
| I Class | $41 | $129 | $225 | $506 |
| A Class | $657 | $831 | $1020 | $1564 |
| R Class | $112 | $350 | $607 | $1340 |
| R6 Class | $26 | $81 | $141 | $319 |

**Portfolio Turnover** 

Because the fund buys and sells shares of other American Century mutual funds directly from the issuers, the fund is not expected to incur transaction costs directly other than transaction costs associated with purchasing exchange-traded funds. However, as a shareholder in the underlying mutual funds, the fund indirectly pays transaction costs, such as commissions, when the underlying mutual funds buy and sell securities (or "turn over" their portfolios). 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 performance. During the most recent fiscal year, the fund's portfolio turnover rate was [48%] of the average value of its portfolio.

**Principal Investment Strategies**

One Choice Blend+ In Retirement Portfolio is a "fund of funds," meaning that it seeks to achieve its objective by investing in other mutual funds advised by American Century (collectively, the underlying funds) that represent a variety of asset classes and investment styles. The underlying stock funds draw on growth, value and quantitative investment techniques and diversify investments among small, medium and large U.S. and foreign companies. The underlying bond funds invest in fixed-income securities that vary by issuer type (corporate and government), credit quality (investment-grade and high-yield or "junk bonds") and geographic exposure (domestic and international). Short-term investments include underlying funds that invest in fixed-income or debt instruments and have a shorter-term weighted average duration, typically three years or less. The following table indicates the fund's neutral mix; that is, how the fund's investments generally will be allocated among the major asset classes as of the date of this prospectus.

---

| | | |
|:---|:---|:---|
| **Equity Securities (Stock Funds)** |  | &nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;**40.0%** |
| &nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;*U.S. Equity* | &nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;*29.5 %* |  |
| &nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;*International Equity* | &nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;*9.5 %* |  |
| &nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;*Real Estate* | &nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;*1.0 %* |  |

| **Short-Term Investments (Short-Term Funds)** |  | &nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;**6.0%** |

---

The neutral mix of One Choice In Retirement Portfolio is expected to remain fixed over time. The fund is generally intended for investors near to, at, or in retirement and who likely are no longer making new investments in the fund. The fund is designed for investors who plan to gradually withdraw the value of their account after retirement. The fund assumes a retirement age of 65 and may not be appropriate for an investor retiring at an age well before or after age 65.

The portfolio managers regularly review the fund's allocations to determine whether rebalancing is appropriate. In order to better balance risks in changing market environments, the portfolio managers may make modest deviations from the neutral mix in light of prevailing market conditions. We reserve the right to modify the neutral mix and underlying funds from time to time should circumstances warrant a change.

**Principal Risks**

• **Allocation Risk** – The fund's performance and risks depend in part on the managers' skill in determining the fund's neutral mix, selecting and weighting the underlying funds, and implementing any deviations from the neutral mix. The managers' evaluations and assumptions regarding asset classes or underlying funds may differ from actual market conditions.

• **Fund of Funds Risks** – The fund's performance and risks reflect the performance and risks of the underlying American Century Investments funds in which it invests. The fund's investment in other American Century Investments funds may create a conflict of interest for the fund's advisor.

• **"Growth" and "Value" Style Risks** – The underlying funds represent a mix of investment styles, each of which has risks associated with it. Growth stocks can be volatile and may lack dividends that can cushion share prices during market declines. Value stocks may continue to be undervalued by the market for long periods of time.

• **Small- and Mid-Cap Stock Risks** – Stocks of smaller companies may be more volatile than larger-company stocks. Smaller companies may have limited financial resources, product lines and markets, and their securities may trade less frequently and in more limited volumes than the securities of larger companies, which could lead to higher transaction costs. To the extent an underlying fund invests in these companies, it may take on more risk.

• **Interest Rate Risk** – Generally, when interest rates rise, the value of an underlying fund's fixed-income securities will decline. The opposite is true when interest rates decline. Underlying funds with longer weighted average maturities are more sensitive to interest rate changes. A period of rising interest rates may negatively affect the performance of underlying fixed-income funds.

------

• **Credit Risk** – The value of an underlying fund's fixed-income securities will be affected adversely by any erosion in the ability of the issuers of these securities to make interest and principal payments as they become due. Changes in the credit rating of a fixed-income security held by an underlying fund could have a similar effect.

• **Foreign Securities Risk** – Some of the underlying funds invest in foreign securities, which are generally riskier than U.S. securities. Political events, social and economic events, natural disasters and public health emergencies occurring in a country where the fund invests could cause the fund's investments in that country to experience gains or losses. Securities of foreign issuers may be less liquid, more volatile and harder to value than U.S. securities. Fluctuations in currency exchange rates also may affect an underlying fund's share price.

• **High-Yield Securities Risk** – Some of the underlying funds may invest in high-yield securities, which are considered to have speculative characteristics and are more likely to be negatively affected by changes in economic conditions.

• **Market Risk** – The value of the fund's shares will go up and down based on the performance of the underlying funds in which it invests. The value of the underlying funds' shares will, in turn, fluctuate based on the performance of the securities they own and other factors generally affecting the securities market. Market risks, including political, regulatory, economic and social developments, can affect the value of the fund's investments. Natural disasters, public health emergencies, war, terrorism and other unforeseeable events may lead to increased market volatility and may have adverse long-term effects on world economies and markets generally.

• **Principal Loss Risk** – At any given time your shares may be worth less than the price you paid for them. In other words, it is possible to lose money by investing in the fund, including losses near to, at, or after retirement. There is no guarantee that the fund will provide adequate income at or through your retirement.

An investment in the fund is not a bank deposit, and it is not insured or guaranteed by the Federal Deposit Insurance Corporation (FDIC) or any other government agency.

**Fund Performance** 

The following bar chart and table provide some indication of the risks of investing in the fund. The bar chart shows changes in the fund's performance from year to year for Investor Class shares. The table shows how the fund's average annual returns for the periods shown compared with those of broad measures of market performance. The table also shows returns for the S&P Target Date Retirement Income Index, which the advisor considers to be more representative of the fund's investment strategy. The fund's past performance (before and after taxes) is not necessarily an indication of how the fund will perform in the future. For current performance information, including yields, please visit americancentury.com.

Sales charges and account fees, if applicable, are not reflected in the bar chart. If those charges were included, returns would be less than those shown.

The after-tax returns are shown only for Investor Class shares. After-tax returns for other share classes will vary. After-tax returns are calculated using the historical highest individual federal marginal income tax rates and do not reflect the impact of state and local taxes. Actual after-tax returns depend on an investor's tax situation and may differ from those shown. After-tax returns are not relevant to investors who hold their fund shares through tax-deferred arrangements, such as 401(k) plans or IRAs.

If you purchase the fund through a broker-dealer or other financial intermediary (such as a bank, insurance company, plan sponsor or financial professional), the fund and its related companies may pay the intermediary for the sale of fund shares and related services in all classes except the R6 Class. These payments may create a conflict of interest by influencing the broker-dealer or other intermediary and your salesperson to recommend the fund over another investment. Ask your salesperson or visit your financial intermediary's website for more information.

**Portfolio Turnover** 

Because the fund buys and sells shares of other American Century mutual funds directly from the issuers, the fund is not expected to incur transaction costs directly other than transaction costs associated with purchasing exchange-traded funds. However, as a shareholder in the underlying mutual funds, the fund indirectly pays transaction costs, such as commissions, when the underlying mutual funds buy and sell securities (or "turn over" their portfolios). 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 performance. During the most recent fiscal year, the fund's portfolio turnover rate was [51%] of the average value of its portfolio.

The target date in the fund name (2025) refers to the approximate year an investor plans to retire and likely would stop making new investments in the fund. The target date does not necessarily represent the specific year you expect to need your assets. It is intended only as a general guide and assumes a retirement age of 65. The fund may not be appropriate for an investor who plans to retire at or near the target date, but at an age well before or after 65. The fund is designed for investors who plan to withdraw the value of their account gradually after retirement. Over time, the fund's neutral mix will become more conservative by decreasing the allocation to stocks and increasing the allocation to bonds and short-term investments. The fund will reach its most conservative allocation approximately five years after the target date, at which point its neutral mix is expected to become fixed at 40% stock funds, 54% bond funds and 6% short-term funds. The following chart shows how the neutral mix is expected to change over time according to a predetermined glide path.

• **Fund of Funds Risks** – The fund's performance and risks reflect the performance and risks of the underlying American Century Investments funds in which it invests. The fund's investment in other American Century Investments funds may create a conflict of interest for the fund's advisor.

• **"Growth" and "Value" Style Risks** – The underlying funds represent a mix of investment styles, each of which has risks associated with it.

Changes in the credit rating of a fixed-income security held by an underlying fund could have a similar effect.

• **Foreign Securities Risk** – Some of the underlying funds invest in foreign securities, which are generally riskier than U.S. securities. Securities of foreign issuers may be less liquid, more volatile and harder to value than U.S. securities. Political events, social and economic events, natural disasters and public health emergencies occurring in a country where the fund invests could cause the fund's investments in that country to experience gains or losses. Fluctuations in currency exchange rates also may affect an underlying fund's share price.

• **High-Yield Securities Risk** – Some of the underlying funds may invest in high-yield securities, which are considered to have speculative characteristics and are more likely to be negatively affected by changes in economic conditions.

• **Market Risk** – The value of the fund's shares will go up and down based on the performance of the underlying funds in which it invests. The value of the underlying funds' shares will, in turn, fluctuate based on the performance of the securities they own and other factors generally affecting the securities market. Market risks, including political, regulatory, economic and social developments, can affect the value of the fund's investments. Natural disasters, public health emergencies, war, terrorism and other unforeseeable events may lead to increased market volatility and may have adverse long-term effects on world economies and markets generally.

• **Principal Loss Risk** – At any given time your shares may be worth less than the price you paid for them. In other words, it is possible to lose money by investing in the fund, including losses near to, at, or after retirement. There is no guarantee that the fund will provide adequate income at or through your retirement.

An investment in the fund is not a bank deposit, and it is not insured or guaranteed by the Federal Deposit Insurance Corporation (FDIC) or any other government agency.

**Fund Performance** 

The following bar chart and table provide some indication of the risks of investing in the fund. The bar chart shows changes in the fund's performance from year to year for Investor Class shares. The table shows how the fund's average annual returns for the periods shown compared with those of broad measures of market performance. The table also shows returns for the S&P Target Date to 2025 Index, which the advisor considers to be more representative of the fund's investment strategy. The fund's past performance (before and after taxes) is not necessarily an indication of how the fund will perform in the future. For current performance information, including yields, please visit americancentury.com.

Sales charges and account fees, if applicable, are not reflected in the bar chart. If those charges were included, returns would be less than those shown.

Box 419200, Kansas City, MO 64141-6200), by telephone at 1-800-345-2021 (Investor Services Representative) or 1-800-345-3533 (Business, Not-For-Profit and Employer-Sponsored Retirement Plans), or through a financial intermediary. Shares may be purchased and redemption proceeds received by electronic bank transfer, by check or by wire.

Unless otherwise specified below, the minimum initial investment amount to open an account is $2,500 ($1,000 for Coverdell Education Savings Accounts and IRAs). However, American Century Investments will waive the fund minimum if you make an initial investment of at least $500 and continue to make automatic investments of at least $100 a month until reaching the fund minimum. Investors opening accounts through financial intermediaries may open an account with $250 for Investor, A and R Classes, but the financial intermediaries may require their clients to meet different investment minimums. The minimum may be waived for broker-dealer sponsored wrap program accounts, fee based accounts, and accounts through bank/trust and wealth management advisory organizations.

The minimum initial investment amount for I Class is generally $5 million ($3 million for endowments and foundations), but the minimum may be waived if you have an aggregate investment in the American Century family of funds of $10 million or more ($5 million for endowments and foundations). This includes accounts held directly with American Century and those held through a financial intermediary.

There is no minimum initial investment amount for R6 Class shares.

For all share classes, there is no minimum initial investment amount for certain employer-sponsored retirement plans, however, financial intermediaries or plan recordkeepers may require plans to meet different minimums. There is a $50 minimum for subsequent purchases, except that there is no subsequent purchase minimum for financial intermediaries or employer-sponsored retirement plans.

**Tax Information**

Fund distributions are generally taxable as ordinary income or capital gains, unless you are investing through a tax-deferred account such as a 401(k) or individual retirement account (in which case you may be taxed upon withdrawal of your investment from such account).

**Payments to Broker-Dealers and Other Financial Intermediaries**

If you purchase the fund through a broker-dealer or other financial intermediary (such as a bank, insurance company, plan sponsor or financial professional), the fund and its related companies may pay the intermediary for the sale of fund shares and related services in all classes except the R6 Class. These payments may create a conflict of interest by influencing the broker-dealer or other intermediary and your salesperson to recommend the fund over another investment. Ask your salesperson or visit your financial intermediary's website for more information.

<sup>1</sup> *Purchases of $1 million or more may be subject to a contingent deferred sales charge of 1.00% if the shares are redeemed within one year of the date of the purchase.*

<sup>2</sup>*&nbsp;&nbsp;&nbsp;&nbsp;The advisor will waive a portion of the fund's management fee equal to the expenses attributable to the management fees of American Century-advised underlying funds. The amount of this waiver will fluctuate depending on the fund's daily allocations to such funds. This waiver is expected to remain in effect permanently, and it cannot be terminated without the approval of the Board of Directors.*

**Example**

The example below is intended to help you compare the costs of investing in the fund with the costs 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 all of your shares at the end of those periods, and that you earn a 5% return each year. The example also assumes that the fund's operating expenses remain the same except that it reflects the rate and duration of any fee waivers noted in the table above. 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* |
| Investor Class | $61 | $193 | $335 | $751 |
| I Class | $41 | $129 | $225 | $506 |
| A Class | $657 | $831 | $1020 | $1564 |
| R Class | $112 | $350 | $607 | $1340 |
| R6 Class | $26 | $81 | $141 | $319 |

**Portfolio Turnover**

Because the fund buys and sells shares of other American Century mutual funds directly from the issuers, the fund is not expected to incur transaction costs directly other than transaction costs associated with purchasing exchange-traded funds. However, as a shareholder in the underlying mutual funds, the fund indirectly pays transaction costs, such as commissions, when the underlying mutual funds buy and sell securities (or "turn over" their portfolios). 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 performance. During the most recent fiscal year, the fund's portfolio turnover rate was [28%] of the average value of its portfolio.

**Principal Investment Strategies**

One Choice Blend+ 2030 Portfolio is a "fund of funds," meaning that it seeks to achieve its objective by investing in other mutual funds advised by American Century (collectively, the underlying funds) that represent a variety of asset classes and investment styles. The underlying stock funds draw on growth, value and quantitative investment techniques and diversify investments among small, medium and large U.S. and foreign companies. The underlying bond funds invest in fixed-income securities that vary by issuer type (corporate and government), credit quality (investment-grade and high-yield or "junk bonds") and geographic exposure (domestic and international). Short-term investments include underlying funds that invest in fixed-income or debt instruments and have a shorter-term weighted average duration, typically three years or less. The following table indicates the fund's neutral mix; that is, how the fund's investments generally will be allocated among the major asset classes as of the date of this prospectus.

---

| | | |
|:---|:---|:---|
| **Equity Securities (Stock Funds)** |  | &nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;**55.0%** |
| &nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;*U.S. Equity* | &nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;*39.1 %* |  |
| &nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;*International Equity* | &nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;*14.4 %* |  |
| &nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;*Real Estate* | &nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;*1.5 %* |  |
| **Fixed-Income Securities (Bond Funds)** |  | &nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;**43.5%** |
| **Short-Term Investments (Short-Term Funds)** |  | &nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;**1.5%** |

The target date in the fund name (2030) refers to the approximate year an investor plans to retire and likely would stop making new investments in the fund. The target date does not necessarily represent the specific year you expect to need your assets. It is intended only as a general guide and assumes a retirement age of 65. The fund may not be appropriate for an investor who plans to retire at or near the target date, but at an age well before or after 65. The fund is designed for investors who plan to withdraw the value of their account gradually after retirement. Over time, the fund's neutral mix will become more conservative by decreasing the allocation to stocks and increasing the allocation to bonds and short-term investments. The fund will reach its most conservative allocation approximately five years after the target date, at which point its neutral mix is expected to become fixed at 40% stock funds, 54% bond funds and 6% short-term funds. The following chart shows how the neutral mix is expected to change over time according to a predetermined glide path.

![glidepath12012024a.jpg](glidepath12012024a.jpg)

------

The portfolio managers regularly review the fund's allocations to determine whether rebalancing is appropriate. In order to better balance risks in changing market environments, the portfolio managers may make modest deviations from the neutral mix in light of prevailing market conditions. We reserve the right to modify the neutral mix and underlying funds from time to time should circumstances warrant a change.

**Principal Risks**

• **Allocation Risk** – The fund's performance and risks depend in part on the managers' skill in determining the fund's neutral mix, selecting and weighting the underlying funds, and implementing any deviations from the neutral mix. The managers' evaluations and assumptions regarding asset classes or underlying funds may differ from actual market conditions.

• **Fund of Funds Risks** – The fund's performance and risks reflect the performance and risks of the underlying American Century Investments funds in which it invests. The fund's investment in other American Century Investments funds may create a conflict of interest for the fund's advisor.

• **"Growth" and "Value" Style Risks** – The underlying funds represent a mix of investment styles, each of which has risks associated with it. Growth stocks can be volatile and may lack dividends that can cushion share prices during market declines. Value stocks may continue to be undervalued by the market for long periods of time.

• **Small- and Mid-Cap Stock Risks** – Stocks of smaller companies may be more volatile than larger-company stocks. Smaller companies may have limited financial resources, product lines and markets, and their securities may trade less frequently and in more limited volumes than the securities of larger companies, which could lead to higher transaction costs. To the extent an underlying fund invests in these companies, it may take on more risk.

• **Interest Rate Risk** – Generally, when interest rates rise, the value of an underlying fund's fixed-income securities will decline. The opposite is true when interest rates decline. Underlying funds with longer weighted average maturities are more sensitive to interest rate changes. A period of rising interest rates may negatively affect the performance of underlying fixed-income funds.

• **Credit Risk** – The value of an underlying fund's fixed-income securities will be affected adversely by any erosion in the ability of the issuers of these securities to make interest and principal payments as they become due. Changes in the credit rating of a fixed-income security held by an underlying fund could have a similar effect.

• **Foreign Securities Risk** – Some of the underlying funds invest in foreign securities, which are generally riskier than U.S. securities. Political events, social and economic events, natural disasters and public health emergencies occurring in a country where the fund invests could cause the fund's investments in that country to experience gains or losses. Securities of foreign issuers may be less liquid, more volatile and harder to value than U.S. securities. Fluctuations in currency exchange rates also may affect an underlying fund's share price. Investing in securities of companies located in emerging market countries is generally riskier than investing in securities of companies located in developed foreign countries.

• **High-Yield Securities Risk** – Some of the underlying funds may invest in high-yield securities, which are considered to have speculative characteristics and are more likely to be negatively affected by changes in economic conditions.

**• Market Risk** – The value of the fund's shares will go up and down based on the performance of the underlying funds in which it invests. The value of the underlying funds' shares will, in turn, fluctuate based on the performance of the securities they own and other factors generally affecting the securities market. Market risks, including political, regulatory, economic and social developments, can affect the value of the fund's investments. Natural disasters, public health emergencies, war, terrorism and other unforeseeable events may lead to increased market volatility and may have adverse long-term effects on world economies and markets generally.

• **Principal Loss Risk** – At any given time your shares may be worth less than the price you paid for them. In other words, it is possible to lose money by investing in the fund, including losses near to, at, or after retirement. There is no guarantee that the fund will provide adequate income at or through your retirement.

An investment in the fund is not a bank deposit, and it is not insured or guaranteed by the Federal Deposit Insurance Corporation (FDIC) or any other government agency.

<sup>2</sup>*&nbsp;&nbsp;&nbsp;&nbsp;The advisor will waive a portion of the fund's management fee equal to the expenses attributable to the management fees of American Century-advised underlying funds. The amount of this waiver will fluctuate depending on the fund's daily allocations to such funds. This waiver is expected to remain in effect permanently, and it cannot be terminated without the approval of the Board of Directors.*

**Example**

The example below is intended to help you compare the costs of investing in the fund with the costs 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 all of your shares at the end of those periods, that you earn 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:

**Portfolio Turnover**

Because the fund buys and sells shares of other American Century mutual funds directly from the issuers, the fund is not expected to incur transaction costs directly other than transaction costs associated with purchasing exchange-traded funds. However, as a shareholder in the underlying mutual funds, the fund indirectly pays transaction costs, such as commissions, when the underlying mutual funds buy and sell securities (or "turn over" their portfolios). 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 performance. During the most recent fiscal year, the fund's portfolio turnover rate was [22%] of the average value of its portfolio.

**Principal Investment Strategies**

One Choice Blend+ 2035 Portfolio is a "fund of funds," meaning that it seeks to achieve its objective by investing in other mutual funds advised by American Century (collectively, the underlying funds) that represent a variety of asset classes and investment styles. The underlying stock funds draw on growth, value and quantitative investment techniques and diversify investments among small, medium and large U.S. and foreign companies. The underlying bond funds invest in fixed-income securities that vary by issuer type (corporate and government), credit quality (investment-grade and high-yield or "junk bonds") and geographic exposure (domestic and international). Short-term investments include underlying funds that invest in fixed-income or debt instruments and have a shorter-term weighted average duration, typically three years or less. The following table indicates the fund's neutral mix; that is, how the fund's investments generally will be allocated among the major asset classes as of the date of this prospectus.

| | | |
|:---|:---|:---|
| **Equity Securities (Stock Funds)** |  | &nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;**63.7%** |
| &nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;*U.S. Equity* | &nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;*44.5 %* |  |

The target date in the fund name (2035) refers to the approximate year an investor plans to retire and likely would stop making new investments in the fund. The target date does not necessarily represent the specific year you expect to need your assets. It is intended only as a general guide and assumes a retirement age of 65. The fund may not be appropriate for an investor who plans to retire at or near the target date, but at an age well before or after 65. The fund is designed for investors who plan to withdraw the value of their account gradually after retirement. Over time, the fund's neutral mix will become more conservative by decreasing the allocation to stocks and increasing the allocation to bonds and short-term investments. The fund will reach its most conservative allocation approximately five years after the target date, at which point its neutral mix is expected to become fixed at 40% stock funds, 54% bond funds and 6% short-term funds. The following chart shows how the neutral mix is expected to change over time according to a predetermined glide path.

![glidepath12012024a.jpg](glidepath12012024a.jpg)

------

The portfolio managers regularly review the fund's allocations to determine whether rebalancing is appropriate. In order to better balance risks in changing market environments, the portfolio managers may make modest deviations from the neutral mix in light of prevailing market conditions. We reserve the right to modify the neutral mix and underlying funds from time to time should circumstances warrant a change.

**Principal Risks**

• **Allocation Risk** – The fund's performance and risks depend in part on the managers' skill in determining the fund's neutral mix, selecting and weighting the underlying funds, and implementing any deviations from the neutral mix. The managers' evaluations and assumptions regarding asset classes or underlying funds may differ from actual market conditions.

• **Fund of Funds Risks** – The fund's performance and risks reflect the performance and risks of the underlying American Century Investments funds in which it invests. The fund's investment in other American Century Investments funds may create a conflict of interest for the fund's advisor.

• **"Growth" and "Value" Style Risks** – The underlying funds represent a mix of investment styles, each of which has risks associated with it. Growth stocks can be volatile and may lack dividends that can cushion share prices during market declines. Value stocks may continue to be undervalued by the market for long periods of time.

• **Small- and Mid-Cap Stock Risks** – Stocks of smaller companies may be more volatile than larger-company stocks. Smaller companies may have limited financial resources, product lines and markets, and their securities may trade less frequently and in more limited volumes than the securities of larger companies, which could lead to higher transaction costs. To the extent an underlying fund invests in these companies, it may take on more risk.

• **Interest Rate Risk** – Generally, when interest rates rise, the value of an underlying fund's fixed-income securities will decline. The opposite is true when interest rates decline. Underlying funds with longer weighted average maturities are more sensitive to interest rate changes. A period of rising interest rates may negatively affect the performance of underlying fixed-income funds.

• **Credit Risk** – The value of an underlying fund's fixed-income securities will be affected adversely by any erosion in the ability of the issuers of these securities to make interest and principal payments as they become due. Changes in the credit rating of a fixed-income security held by an underlying fund could have a similar effect.

• **Foreign Securities Risk** – Some of the underlying funds invest in foreign securities, which are generally riskier than U.S. securities. Political events, social and economic events, natural disasters and public health emergencies occurring in a country where the fund invests could cause the fund's investments in that country to experience gains or losses. Securities of foreign issuers may be less liquid, more volatile and harder to value than U.S. securities. Fluctuations in currency exchange rates also may affect an underlying fund's share price.

• **Emerging Market Risk** - Investing in securities of companies located in emerging market countries generally is also riskier than investing in securities of companies located in foreign developed countries. Emerging market countries may have unstable governments and/or economies that are subject to sudden change. These changes may be magnified by the countries' emergent financial markets, resulting in significant volatility to investments in these countries.

• **Market Risk** – The value of the fund's shares will go up and down based on the performance of the underlying funds in which it invests. The value of the underlying funds' shares will, in turn, fluctuate based on the performance of the securities they own and other factors generally affecting the securities market. Market risks, including political, regulatory, economic and social developments, can affect the value of the fund's investments. Natural disasters, public health emergencies, war, terrorism and other unforeseeable events may lead to increased market volatility and may have adverse long-term effects on world economies and markets generally.

• **Principal Loss Risk** – At any given time your shares may be worth less than the price you paid for them. In other words, it is possible to lose money by investing in the fund, including losses near to, at, or after retirement. There is no guarantee that the fund will provide adequate income at or through your retirement.

An investment in the fund is not a bank deposit, and it is not insured or guaranteed by the Federal Deposit Insurance Corporation (FDIC) or any other government agency.

**Fund Performance** 

The following bar chart and table provide some indication of the risks of investing in the fund. The bar chart shows changes in the fund's performance from year to year for Investor Class shares. The table shows how the fund's average annual returns for the periods shown compared with those of broad measures of market performance. The table also shows returns for the S&P Target Date to 2035 Index, which the advisor considers to be more representative of the fund's investment strategy. The fund's past performance (before and after taxes) is not necessarily an indication of how the fund will perform in the future.

The after-tax returns are shown only for Investor Class shares. After-tax returns for other share classes will vary. After-tax returns are calculated using the historical highest individual federal marginal income tax rates and do not reflect the impact of state and local taxes. Actual after-tax returns depend on an investor's tax situation and may differ from those shown. After-tax returns are not relevant to investors who hold their fund shares through tax-deferred arrangements, such as 401(k) plans or IRAs.

The minimum initial investment amount for I Class is generally $5 million ($3 million for endowments and foundations), but the minimum may be waived if you have an aggregate investment in the American Century family of funds of $10 million or more ($5 million for endowments and foundations). This includes accounts held directly with American Century and those held through a financial intermediary.

There is no minimum initial investment amount for R6 Class shares.

For all share classes, there is no minimum initial investment amount for certain employer-sponsored retirement plans, however, financial intermediaries or plan recordkeepers may require plans to meet different minimums. There is a $50 minimum for subsequent purchases, except that there is no subsequent purchase minimum for financial intermediaries or employer-sponsored retirement plans.

**Tax Information**

Fund distributions are generally taxable as ordinary income or capital gains, unless you are investing through a tax-deferred account such as a 401(k) or individual retirement account (in which case you may be taxed upon withdrawal of your investment from such account).

**Payments to Broker-Dealers and Other Financial Intermediaries**

If you purchase the fund through a broker-dealer or other financial intermediary (such as a bank, insurance company, plan sponsor or financial professional), the fund and its related companies may pay the intermediary for the sale of fund shares and related services in all classes except the R6 Class. These payments may create a conflict of interest by influencing the broker-dealer or other intermediary and your salesperson to recommend the fund over another investment. Ask your salesperson or visit your financial intermediary's website for more information.

**Example**

The example below is intended to help you compare the costs of investing in the fund with the costs 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 all of your shares at the end of those periods, that you earn 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* | *5 years* | *10 years* |
| Investor Class | $60 | $189 | $330 | $738 |
| I Class | $40 | $126 | $219 | $493 |
| A Class | $656 | $828 | $1015 | $1553 |
| R Class | $111 | $347 | $602 | $1329 |
| R6 Class | $25 | $77 | $135 | $306 |

**Portfolio Turnover** 

Because the fund buys and sells shares of other American Century mutual funds directly from the issuers, the fund is not expected to incur transaction costs directly other than transaction costs associated with purchasing exchange-traded funds. However, as a shareholder in the underlying mutual funds, the fund indirectly pays transaction costs, such as commissions, when the underlying mutual funds buy and sell securities (or "turn over" their portfolios). 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 performance. During the most recent fiscal year, the fund's portfolio turnover rate was [23%] of the average value of its portfolio.

**Principal Investment Strategies**

One Choice Blend+ 2040 Portfolio is a "fund of funds," meaning that it seeks to achieve its objective by investing in other mutual funds advised by American Century (collectively, the underlying funds) that represent a variety of asset classes and investment styles. The underlying stock funds draw on growth, value and quantitative investment techniques and diversify investments among small, medium and large U.S. and foreign companies. The underlying bond funds invest in fixed-income securities that vary by issuer type (corporate and government), credit quality (investment-grade and high-yield or "junk bonds") and geographic exposure (domestic and international). Short-term investments include underlying funds that invest in fixed-income or debt instruments and have a shorter-term weighted average duration, typically three years or less. The following table indicates the fund's neutral mix; that is, how the fund's investments generally will be allocated among the major asset classes as of the date of this prospectus.

The target date in the fund name (2040) refers to the approximate year an investor plans to retire and likely would stop making new investments in the fund. The target date does not necessarily represent the specific year you expect to need your assets. It is intended only as a general guide and assumes a retirement age of 65. The fund may not be appropriate for an investor who plans to retire at or near the target date, but at an age well before or after 65. The fund is designed for investors who plan to withdraw the value of their account gradually after retirement. Over time, the fund's neutral mix will become more conservative by decreasing the allocation to stocks and increasing the allocation to bonds and short-term investments. The fund will reach its most conservative allocation approximately five years after the target date, at which point its neutral mix is expected to become fixed at 40% stock funds, 54% bond funds and 6% short-term funds. The following chart shows how the neutral mix is expected to change over time according to a predetermined glide path.

![glidepath12012024a.jpg](glidepath12012024a.jpg)

The portfolio managers regularly review the fund's allocations to determine whether rebalancing is appropriate. In order to better balance risks in changing market environments, the portfolio managers may make modest deviations from the neutral mix in light of prevailing market conditions. We reserve the right to modify the neutral mix and underlying funds from time to time should circumstances warrant a change.

**Principal Risks**

• **Allocation Risk** – The fund's performance and risks depend in part on the managers' skill in determining the fund's neutral mix, selecting and weighting the underlying funds, and implementing any deviations from the neutral mix. The managers' evaluations and assumptions regarding asset classes or underlying funds may differ from actual market conditions.

------

• **Fund of Funds Risks** – The fund's performance and risks reflect the performance and risks of the underlying American Century Investments funds in which it invests. The fund's investment in other American Century Investments funds may create a conflict of interest for the fund's advisor.

• **"Growth" and "Value" Style Risks** – The underlying funds represent a mix of investment styles, each of which has risks associated with it. Growth stocks can be volatile and may lack dividends that can cushion share prices during market declines. Value stocks may continue to be undervalued by the market for long periods of time.

• **Small- and Mid-Cap Stock Risks** – Stocks of smaller companies may be more volatile than larger-company stocks. Smaller companies may have limited financial resources, product lines and markets, and their securities may trade less frequently and in more limited volumes than the securities of larger companies, which could lead to higher transaction costs. To the extent an underlying fund invests in these companies, it may take on more risk.

• **Interest Rate Risk** – Generally, when interest rates rise, the value of an underlying fund's fixed-income securities will decline. The opposite is true when interest rates decline. Underlying funds with longer weighted average maturities are more sensitive to interest rate changes. A period of rising interest rates may negatively affect the performance of underlying fixed-income funds.

• **Credit Risk** – The value of an underlying fund's fixed-income securities will be affected adversely by any erosion in the ability of the issuers of these securities to make interest and principal payments as they become due. Changes in the credit rating of a fixed-income security held by an underlying fund could have a similar effect.

• **Foreign Securities Risk** – Some of the underlying funds invest in foreign securities, which are generally riskier than U.S. securities. Political events, social and economic events, natural disasters and public health emergencies occurring in a country where the fund invests could cause the fund's investments in that country to experience gains or losses. Securities of foreign issuers may be less liquid, more volatile and harder to value than U.S. securities. Fluctuations in currency exchange rates also may affect an underlying fund's share price.

• **Emerging Market Risk** - Investing in securities of companies located in emerging market countries generally is also riskier than investing in securities of companies located in foreign developed countries. Emerging market countries may have unstable governments and/or economies that are subject to sudden change. These changes may be magnified by the countries' emergent financial markets, resulting in significant volatility to investments in these countries.

**• Market Risk** – The value of the fund's shares will go up and down based on the performance of the underlying funds in which it invests. The value of the underlying funds' shares will, in turn, fluctuate based on the performance of the securities they own and other factors generally affecting the securities market. Market risks, including political, regulatory, economic and social developments, can affect the value of the fund's investments. Natural disasters, public health emergencies, war, terrorism and other unforeseeable events may lead to increased market volatility and may have adverse long-term effects on world economies and markets generally.

• **Principal Loss Risk** – At any given time your shares may be worth less than the price you paid for them. In other words, it is possible to lose money by investing in the fund, including losses near to, at, or after retirement. There is no guarantee that the fund will provide adequate income at or through your retirement.

An investment in the fund is not a bank deposit, and it is not insured or guaranteed by the Federal Deposit Insurance Corporation (FDIC) or any other government agency.

**Fund Performance** 

The following bar chart and table provide some indication of the risks of investing in the fund. The bar chart shows changes in the fund's performance from year to year for Investor Class shares. The table shows how the fund's average annual returns for the periods shown compared with those of broad measures of market performance. The table also shows returns for the S&P Target Date to 2040 Index, which the advisor considers to be more representative of the fund's investment strategy. The fund's past performance (before and after taxes) is not necessarily an indication of how the fund will perform in the future.

Sales charges and account fees, if applicable, are not reflected in the bar chart. If those charges were included, returns would be less than those shown.

The after-tax returns are shown only for Investor Class shares. After-tax returns for other share classes will vary. After-tax returns are calculated using the historical highest individual federal marginal income tax rates and do not reflect the impact of state and local taxes. Actual after-tax returns depend on an investor's tax situation and may differ from those shown. After-tax returns are not relevant to investors who hold their fund shares through tax-deferred arrangements, such as 401(k) plans or IRAs.

**Purchase and Sale of Fund Shares**

You may purchase or redeem shares of the fund on any business day through our website at americancentury.com, in person (at one of our Investor Centers), by mail (American Century Investments, P.O. Box 419200, Kansas City, MO 64141-6200), by telephone at 1-800-345-2021 (Investor Services Representative) or 1-800-345-3533 (Business, Not-For-Profit and Employer-Sponsored Retirement Plans), or through a financial intermediary. Shares may be purchased and redemption proceeds received by electronic bank transfer, by check or by wire.

Unless otherwise specified below, the minimum initial investment amount to open an account is $2,500 ($1,000 for Coverdell Education Savings Accounts and IRAs). However, American Century Investments will waive the fund minimum if you make an initial investment of at least $500 and continue to make automatic investments of at least $100 a month until reaching the fund minimum. Investors opening accounts through financial intermediaries may open an account with $250 for Investor, A and R Classes, but the financial intermediaries may require their clients to meet different investment minimums. The minimum may be waived for broker-dealer sponsored wrap program accounts, fee based accounts, and accounts through bank/trust and wealth management advisory organizations.

The minimum initial investment amount for I Class is generally $5 million ($3 million for endowments and foundations), but the minimum may be waived if you have an aggregate investment in the American Century family of funds of $10 million or more ($5 million for endowments and foundations). This includes accounts held directly with American Century and those held through a financial intermediary.

There is no minimum initial investment amount for R6 Class shares.

For all share classes, there is no minimum initial investment amount for certain employer-sponsored retirement plans, however, financial intermediaries or plan recordkeepers may require plans to meet different minimums. There is a $50 minimum for subsequent purchases, except that there is no subsequent purchase minimum for financial intermediaries or employer-sponsored retirement plans.

**Tax Information** 

Fund distributions are generally taxable as ordinary income or capital gains, unless you are investing through a tax-deferred account such as a 401(k) or individual retirement account (in which case you may be taxed upon withdrawal of your investment from such account).

**Payments to Broker-Dealers and Other Financial Intermediaries** 

If you purchase the fund through a broker-dealer or other financial intermediary (such as a bank, insurance company, plan sponsor or financial professional), the fund and its related companies may pay the intermediary for the sale of fund shares and related services in all classes except the R6 Class. These payments may create a conflict of interest by influencing the broker-dealer or other intermediary and your salesperson to recommend the fund over another investment. Ask your salesperson or visit your financial intermediary's website for more information.

**Example**

The example below is intended to help you compare the costs of investing in the fund with the costs 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 all of your shares at the end of those periods, that you earn 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* | *5 years* | *10 years* |
| Investor Class | $60 | $189 | $330 | $738 |
| I Class | $40 | $126 | $219 | $493 |
| A Class | $656 | $828 | $1015 | $1553 |
| R Class | $111 | $347 | $602 | $1329 |
| R6 Class | $25 | $77 | $135 | $306 |

**Portfolio Turnover**

Because the fund buys and sells shares of other American Century mutual funds directly from the issuers, the fund is not expected to incur transaction costs directly other than transaction costs associated with purchasing exchange-traded funds. However, as a shareholder in the underlying mutual funds, the fund indirectly pays transaction costs, such as commissions, when the underlying mutual funds buy and sell securities (or "turn over" their portfolios). 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 performance. During the most recent fiscal year, the fund's portfolio turnover rate was [43%] of the average value of its portfolio.

**Principal Investment Strategies**

One Choice Blend+ 2045 Portfolio is a "fund of funds," meaning that it seeks to achieve its objective by investing in other mutual funds advised by American Century (collectively, the underlying funds) that represent a variety of asset classes and investment styles. The underlying stock funds draw on growth, value and quantitative investment techniques and diversify investments among small, medium and large U.S. and foreign companies. The underlying bond funds invest in fixed-income securities that vary by issuer type (corporate and government), credit quality (investment-grade and high-yield or "junk bonds") and geographic exposure (domestic and international). Short-term investments include underlying funds that invest in fixed-income or debt instruments and have a shorter-term weighted average duration, typically three years or less. The following table indicates the fund's neutral mix; that is, how the fund's investments generally will be allocated among the major asset classes as of the date of this prospectus.

---

| | | |
|:---|:---|:---|
| **Equity Securities (Stock Funds)** |  | &nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;**80.0%** |
| &nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;*U.S. Equity* | &nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;*54.8 %* |  |
| &nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;*International Equity* | &nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;*22.8 %* |  |
| &nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;*Real Estate* | &nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;*2.4 %* |  |
| **Fixed-Income Securities (Bond Funds)** |  | &nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;**20.0%** |
| **Short-Term Investments (Short-Term Funds)** |  | &nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;**0.0%** |

---

The target date in the fund name (2045) refers to the approximate year an investor plans to retire and likely would stop making new investments in the fund. The target date does not necessarily represent the specific year you expect to need your assets. It is intended only as a general guide and assumes a retirement age of 65. The fund may not be appropriate for an investor who plans to retire at or near the target date, but at an age well before or after 65. The fund is designed for investors who plan to withdraw the value of their account gradually after retirement. Over time, the fund's neutral mix will become more conservative by decreasing the allocation to stocks and increasing the allocation to bonds and short-term investments. The fund will reach its most conservative allocation approximately five years after the target date, at which point its neutral mix is expected to become fixed at 40% stock funds, 54% bond funds and 6% short-term funds. The following chart shows how the neutral mix is expected to change over time according to a predetermined glide path.

![glidepath12012024a.jpg](glidepath12012024a.jpg)

The portfolio managers regularly review the fund's allocations to determine whether rebalancing is appropriate. In order to better balance risks in changing market environments, the portfolio managers may make modest deviations from the neutral mix in light of prevailing market conditions. We reserve the right to modify the neutral mix and underlying funds from time to time should circumstances warrant a change.

**Principal Risks**

• **Allocation Risk** – The fund's performance and risks depend in part on the managers' skill in determining the fund's neutral mix, selecting and weighting the underlying funds, and implementing any deviations from the neutral mix. The managers' evaluations and assumptions regarding asset classes or underlying funds may differ from actual market conditions.

------

• **Fund of Funds Risks** – The fund's performance and risks reflect the performance and risks of the underlying American Century Investments funds in which it invests. The fund's investment in other American Century Investments funds may create a conflict of interest for the fund's advisor.

• **"Growth" and "Value" Style Risks** – The underlying funds represent a mix of investment styles, each of which has risks associated with it. Growth stocks can be volatile and may lack dividends that can cushion share prices during market declines. Value stocks may continue to be undervalued by the market for long periods of time.

• **Small- and Mid-Cap Stock Risks** – Stocks of smaller companies may be more volatile than larger-company stocks. Smaller companies may have limited financial resources, product lines and markets, and their securities may trade less frequently and in more limited volumes than the securities of larger companies, which could lead to higher transaction costs. To the extent an underlying fund invests in these companies, it may take on more risk.

• **Interest Rate Risk** – Generally, when interest rates rise, the value of an underlying fund's fixed-income securities will decline. The opposite is true when interest rates decline. Underlying funds with longer weighted average maturities are more sensitive to interest rate changes. A period of rising interest rates may negatively affect the performance of underlying fixed-income funds.

• **Credit Risk** – The value of an underlying fund's fixed-income securities will be affected adversely by any erosion in the ability of the issuers of these securities to make interest and principal payments as they become due. Changes in the credit rating of a fixed-income security held by an underlying fund could have a similar effect.

• **Foreign Securities Risk** – Some of the underlying funds invest in foreign securities, which are generally riskier than U.S. securities. Political events, social and economic events, natural disasters and public health emergencies occurring in a country where the fund invests could cause the fund's investments in that country to experience gains or losses. Securities of foreign issuers may be less liquid, more volatile and harder to value than U.S. securities. Fluctuations in currency exchange rates also may affect an underlying fund's share price.

• **Emerging Market Risk** - Investing in securities of companies located in emerging market countries generally is also riskier than investing in securities of companies located in foreign developed countries. Emerging market countries may have unstable governments and/or economies that are subject to sudden change. These changes may be magnified by the countries' emergent financial markets, resulting in significant volatility to investments in these countries.

**• Market Risk** – The value of the fund's shares will go up and down based on the performance of the underlying funds in which it invests. The value of the underlying funds' shares will, in turn, fluctuate based on the performance of the securities they own and other factors generally affecting the securities market. Market risks, including political, regulatory, economic and social developments, can affect the value of the fund's investments. Natural disasters, public health emergencies, war, terrorism and other unforeseeable events may lead to increased market volatility and may have adverse long-term effects on world economies and markets generally.

• **Principal Loss Risk** – At any given time your shares may be worth less than the price you paid for them. In other words, it is possible to lose money by investing in the fund, including losses near to, at, or after retirement. There is no guarantee that the fund will provide adequate income at or through your retirement.

An investment in the fund is not a bank deposit, and it is not insured or guaranteed by the Federal Deposit Insurance Corporation (FDIC) or any other government agency.

**Fund Performance** 

The following bar chart and table provide some indication of the risks of investing in the fund. The bar chart shows changes in the fund's performance from year to year for Investor Class shares. The table shows how the fund's average annual returns for the periods shown compared with those of broad measures of market performance. The table also shows returns for the S&P Target Date to 2045 Index, which the advisor considers to be more representative of the fund's investment strategy. The fund's past performance (before and after taxes) is not necessarily an indication of how the fund will perform in the future. For current performance information, including yields, please visit americancentury.com.

Sales charges and account fees, if applicable, are not reflected in the bar chart. If those charges were included, returns would be less than those shown.

<sup>1</sup> *Purchases of $1 million or more may be subject to a contingent deferred sales charge of 1.00% if the shares are redeemed within one year of the date of the purchase.*

**Example**

The example below is intended to help you compare the costs of investing in the fund with the costs 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 all of your shares at the end of those periods, that you earn 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* | *5 years* | *10 years* |
| Investor Class | $60 | $189 | $330 | $738 |
| I Class | $40 | $126 | $219 | $493 |
| A Class | $656 | $828 | $1015 | $1553 |
| R Class | $111 | $347 | $602 | $1329 |
| R6 Class | $25 | $77 | $135 | $306 |

---

**Portfolio Turnover**

Because the fund buys and sells shares of other American Century mutual funds directly from the issuers, the fund is not expected to incur transaction costs directly other than transaction costs associated with purchasing exchange-traded funds. However, as a shareholder in the underlying mutual funds, the fund indirectly pays transaction costs, such as commissions, when the underlying mutual funds buy and sell securities (or "turn over" their portfolios). 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 performance. During the most recent fiscal year, the fund's portfolio turnover rate was [18%] of the average value of its portfolio.

One Choice Blend+ 2050 Portfolio is a "fund of funds," meaning that it seeks to achieve its objective by investing in other mutual funds advised by American Century (collectively, the underlying funds) that represent a variety of asset classes and investment styles. The underlying stock funds draw on growth, value and quantitative investment techniques and diversify investments among small, medium and large U.S. and foreign companies. The underlying bond funds invest in fixed-income securities that vary by issuer type (corporate and government), credit quality (investment-grade and high-yield or "junk bonds") and geographic exposure (domestic and international). Short-term investments include underlying funds that invest in fixed-income or debt instruments and have a shorter-term weighted average duration, typically three years or less. The following table indicates the fund's neutral mix; that is, how the fund's investments generally will be allocated among the major asset classes as of the date of this prospectus.

The target date in the fund name (2050) refers to the approximate year an investor plans to retire and likely would stop making new investments in the fund. The target date does not necessarily represent the specific year you expect to need your assets. It is intended only as a general guide and assumes a retirement age of 65. The fund may not be appropriate for an investor who plans to retire at or near the target date, but at an age well before or after 65. The fund is designed for investors who plan to withdraw the value of their account gradually after retirement. Over time, the fund's neutral mix will become more conservative by decreasing the allocation to stocks and increasing the allocation to bonds and short-term investments. The fund will reach its most conservative allocation approximately five years after the target date, at which point its neutral mix is expected to become fixed at 40% stock funds, 54% bond funds and 6% short-term funds. The following chart shows how the neutral mix is expected to change over time according to a predetermined glide path.

![glidepath12012024a.jpg](glidepath12012024a.jpg)

The portfolio managers regularly review the fund's allocations to determine whether rebalancing is appropriate. In order to better balance risks in changing market environments, the portfolio managers may make modest deviations from the neutral mix in light of prevailing market conditions. We reserve the right to modify the neutral mix and underlying funds from time to time should circumstances warrant a change.

**Principal Risks**

• **Allocation Risk** – The fund's performance and risks depend in part on the managers' skill in determining the fund's neutral mix, selecting and weighting the underlying funds, and implementing any deviations from the neutral mix. The managers' evaluations and assumptions regarding asset classes or underlying funds may differ from actual market conditions.

------

• **Fund of Funds Risks** – The fund's performance and risks reflect the performance and risks of the underlying American Century Investments funds in which it invests. The fund's investment in other American Century Investments funds may create a conflict of interest for the fund's advisor.

• **"Growth" and "Value" Style Risks** – The underlying funds represent a mix of investment styles, each of which has risks associated with it. Growth stocks can be volatile and may lack dividends that can cushion share prices during market declines. Value stocks may continue to be undervalued by the market for long periods of time.

• **Small- and Mid-Cap Stock Risks** – Stocks of smaller companies may be more volatile than larger-company stocks. Smaller companies may have limited financial resources, product lines and markets, and their securities may trade less frequently and in more limited volumes than the securities of larger companies, which could lead to higher transaction costs. To the extent an underlying fund invests in these companies, it may take on more risk.

• **Interest Rate Risk** – Generally, when interest rates rise, the value of an underlying fund's fixed-income securities will decline. The opposite is true when interest rates decline. Underlying funds with longer weighted average maturities are more sensitive to interest rate changes. A period of rising interest rates may negatively affect the performance of underlying fixed-income funds.

• **Credit Risk** – The value of an underlying fund's fixed-income securities will be affected adversely by any erosion in the ability of the issuers of these securities to make interest and principal payments as they become due. Changes in the credit rating of a fixed-income security held by an underlying fund could have a similar effect.

• **Foreign Securities Risk** – Some of the underlying funds invest in foreign securities, which are generally riskier than U.S. securities. Political events, social and economic events, natural disasters and public health emergencies occurring in a country where the fund invests could cause the fund's investments in that country to experience gains or losses. Securities of foreign issuers may be less liquid, more volatile and harder to value than U.S. securities. Fluctuations in currency exchange rates also may affect an underlying fund's share price.

• **Emerging Market Risk** - Investing in securities of companies located in emerging market countries generally is also riskier than investing in securities of companies located in foreign developed countries. Emerging market countries may have unstable governments and/or economies that are subject to sudden change. These changes may be magnified by the countries' emergent financial markets, resulting in significant volatility to investments in these countries.

**• Market Risk** – The value of the fund's shares will go up and down based on the performance of the underlying funds in which it invests. The value of the underlying funds' shares will, in turn, fluctuate based on the performance of the securities they own and other factors generally affecting the securities market. Market risks, including political, regulatory, economic and social developments, can affect the value of the fund's investments. Natural disasters, public health emergencies, war, terrorism and other unforeseeable events may lead to increased market volatility and may have adverse long-term effects on world economies and markets generally.

• **Principal Loss Risk** – At any given time your shares may be worth less than the price you paid for them. In other words, it is possible to lose money by investing in the fund, including losses near to, at, or after retirement. There is no guarantee that the fund will provide adequate income at or through your retirement.

An investment in the fund is not a bank deposit, and it is not insured or guaranteed by the Federal Deposit Insurance Corporation (FDIC) or any other government agency.

**Fund Performance** 

The following bar chart and table provide some indication of the risks of investing in the fund. The bar chart shows changes in the fund's performance from year to year for Investor Class shares. The table shows how the fund's average annual returns for the periods shown compared with those of broad measures of market performance. The table also shows returns for the S&P Target Date to 2050 Index, which the advisor considers to be more representative of the fund's investment strategy. The fund's past performance (before and after taxes) is not necessarily an indication of how the fund will perform in the future. For current performance information, including yields, please visit americancentury.com.

Sales charges and account fees, if applicable, are not reflected in the bar chart. If those charges were included, returns would be less than those shown.

The after-tax returns are shown only for Investor Class shares. After-tax returns for other share classes will vary. After-tax returns are calculated using the historical highest individual federal marginal income tax rates and do not reflect the impact of state and local taxes. Actual after-tax returns depend on an investor's tax situation and may differ from those shown. After-tax returns are not relevant to investors who hold their fund shares through tax-deferred arrangements, such as 401(k) plans or IRAs.

**Purchase and Sale of Fund Shares**

You may purchase or redeem shares of the fund on any business day through our website at americancentury.com, in person (at one of our Investor Centers), by mail (American Century Investments, P.O. Box 419200, Kansas City, MO 64141-6200), by telephone at 1-800-345-2021 (Investor Services Representative) or 1-800-345-3533 (Business, Not-For-Profit and Employer-Sponsored Retirement Plans), or through a financial intermediary. Shares may be purchased and redemption proceeds received by electronic bank transfer, by check or by wire.

Unless otherwise specified below, the minimum initial investment amount to open an account is $2,500 ($1,000 for Coverdell Education Savings Accounts and IRAs). However, American Century Investments will waive the fund minimum if you make an initial investment of at least $500 and continue to make automatic investments of at least $100 a month until reaching the fund minimum. Investors opening accounts through financial intermediaries may open an account with $250 for Investor, A and R Classes, but the financial intermediaries may require their clients to meet different investment minimums. The minimum may be waived for broker-dealer sponsored wrap program accounts, fee based accounts, and accounts through bank/trust and wealth management advisory organizations.

The minimum initial investment amount for I Class is generally $5 million ($3 million for endowments and foundations), but the minimum may be waived if you have an aggregate investment in the American Century family of funds of $10 million or more ($5 million for endowments and foundations). This includes accounts held directly with American Century and those held through a financial intermediary.

There is no minimum initial investment amount for R6 Class shares.

For all share classes, there is no minimum initial investment amount for certain employer-sponsored retirement plans, however, financial intermediaries or plan recordkeepers may require plans to meet different minimums. There is a $50 minimum for subsequent purchases, except that there is no subsequent purchase minimum for financial intermediaries or employer-sponsored retirement plans.

**Tax Information**

Fund distributions are generally taxable as ordinary income or capital gains, unless you are investing through a tax-deferred account such as a 401(k) or individual retirement account (in which case you may be taxed upon withdrawal of your investment from such account).

**Payments to Broker-Dealers and Other Financial Intermediaries**

If you purchase the fund through a broker-dealer or other financial intermediary (such as a bank, insurance company, plan sponsor or financial professional), the fund and its related companies may pay the intermediary for the sale of fund shares and related services in all classes except the R6 Class. These payments may create a conflict of interest by influencing the broker-dealer or other intermediary and your salesperson to recommend the fund over another investment. Ask your salesperson or visit your financial intermediary's website for more information.

**Example**

The example below is intended to help you compare the costs of investing in the fund with the costs 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 all of your shares at the end of those periods, that you earn 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* | *5 years* | *10 years* |
| Investor Class | $60 | $189 | $330 | $738 |
| I Class | $40 | $126 | $219 | $493 |
| A Class | $656 | $828 | $1015 | $1553 |
| R Class | $111 | $347 | $602 | $1329 |
| R6 Class | $25 | $77 | $135 | $306 |

---

**Portfolio Turnover**

Because the fund buys and sells shares of other American Century mutual funds directly from the issuers, the fund is not expected to incur transaction costs directly other than transaction costs associated with purchasing exchange-traded funds. However, as a shareholder in the underlying mutual funds, the fund indirectly pays transaction costs, such as commissions, when the underlying mutual funds buy and sell securities (or "turn over" their portfolios). 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 performance. During the most recent fiscal year, the fund's portfolio turnover rate was [18%] of the average value of its portfolio.

The target date in the fund name (2055) refers to the approximate year an investor plans to retire and likely would stop making new investments in the fund. The target date does not necessarily represent the specific year you expect to need your assets. It is intended only as a general guide and assumes a retirement age of 65. The fund may not be appropriate for an investor who plans to retire at or near the target date, but at an age well before or after 65. The fund is designed for investors who plan to withdraw the value of their account gradually after retirement. Over time, the fund's neutral mix will become more conservative by decreasing the allocation to stocks and increasing the allocation to bonds and short-term investments. The fund will reach its most conservative allocation approximately five years after the target date, at which point its neutral mix is expected to become fixed at 40% stock funds, 54% bond funds and 6% short-term funds. The following chart shows how the neutral mix is expected to change over time according to a predetermined glide path.

![glidepath12012024a.jpg](glidepath12012024a.jpg)

The portfolio managers regularly review the fund's allocations to determine whether rebalancing is appropriate. In order to better balance risks in changing market environments, the portfolio managers may make modest deviations from the neutral mix in light of prevailing market conditions. We reserve the right to modify the neutral mix and underlying funds from time to time should circumstances warrant a change.

**Principal Risks**

• **Allocation Risk** – The fund's performance and risks depend in part on the managers' skill in determining the fund's neutral mix, selecting and weighting the underlying funds, and implementing any deviations from the neutral mix. The managers' evaluations and assumptions regarding asset classes or underlying funds may differ from actual market conditions.

------

• **Fund of Funds Risks** – The fund's performance and risks reflect the performance and risks of the underlying American Century Investments funds in which it invests. The fund's investment in other American Century Investments funds may create a conflict of interest for the fund's advisor.

• **"Growth" and "Value" Style Risks** – The underlying funds represent a mix of investment styles, each of which has risks associated with it. Growth stocks can be volatile and may lack dividends that can cushion share prices during market declines. Value stocks may continue to be undervalued by the market for long periods of time.

• **Small- and Mid-Cap Stock Risks** – Stocks of smaller companies may be more volatile than larger-company stocks. Smaller companies may have limited financial resources, product lines and markets, and their securities may trade less frequently and in more limited volumes than the securities of larger companies, which could lead to higher transaction costs. To the extent an underlying fund invests in these companies, it may take on more risk.

• **Interest Rate Risk** – Generally, when interest rates rise, the value of an underlying fund's fixed-income securities will decline. The opposite is true when interest rates decline. Underlying funds with longer weighted average maturities are more sensitive to interest rate changes. A period of rising interest rates may negatively affect the performance of underlying fixed-income funds.

• **Credit Risk** – The value of an underlying fund's fixed-income securities will be affected adversely by any erosion in the ability of the issuers of these securities to make interest and principal payments as they become due. Changes in the credit rating of a fixed-income security held by an underlying fund could have a similar effect.

• **Foreign Securities Risk** – Some of the underlying funds invest in foreign securities, which are generally riskier than U.S. securities. Political events, social and economic events, natural disasters and public health emergencies occurring in a country where the fund invests could cause the fund's investments in that country to experience gains or losses. Securities of foreign issuers may be less liquid, more volatile and harder to value than U.S. securities. Fluctuations in currency exchange rates also may affect an underlying fund's share price.

• **Emerging Market Risk** - Investing in securities of companies located in emerging market countries generally is also riskier than investing in securities of companies located in foreign developed countries. Emerging market countries may have unstable governments and/or economies that are subject to sudden change. These changes may be magnified by the countries' emergent financial markets, resulting in significant volatility to investments in these countries.

**• Market Risk** – The value of the fund's shares will go up and down based on the performance of the underlying funds in which it invests. The value of the underlying funds' shares will, in turn, fluctuate based on the performance of the securities they own and other factors generally affecting the securities market. Market risks, including political, regulatory, economic and social developments, can affect the value of the fund's investments. Natural disasters, public health emergencies, war, terrorism and other unforeseeable events may lead to increased market volatility and may have adverse long-term effects on world economies and markets generally.

• **Principal Loss Risk** – At any given time your shares may be worth less than the price you paid for them. In other words, it is possible to lose money by investing in the fund, including losses near to, at, or after retirement. There is no guarantee that the fund will provide adequate income at or through your retirement.

An investment in the fund is not a bank deposit, and it is not insured or guaranteed by the Federal Deposit Insurance Corporation (FDIC) or any other government agency.

**Fund Performance** 

The following bar chart and table provide some indication of the risks of investing in the fund. The bar chart shows changes in the fund's performance from year to year for Investor Class shares. The table shows how the fund's average annual returns for the periods shown compared with those of broad measures of market performance. The table also shows returns for the S&P Target Date to 2055 Index, which the advisor considers to be more representative of the fund's investment strategy. The fund's past performance (before and after taxes) is not necessarily an indication of how the fund will perform in the future.

Sales charges and account fees, if applicable, are not reflected in the bar chart. If those charges were included, returns would be less than those shown.

Box 419200, Kansas City, MO 64141-6200), by telephone at 1-800-345-2021 (Investor Services Representative) or 1-800-345-3533 (Business, Not-For-Profit and Employer-Sponsored Retirement Plans), or through a financial intermediary. Shares may be purchased and redemption proceeds received by electronic bank transfer, by check or by wire.

Unless otherwise specified below, the minimum initial investment amount to open an account is $2,500 ($1,000 for Coverdell Education Savings Accounts and IRAs). However, American Century Investments will waive the fund minimum if you make an initial investment of at least $500 and continue to make automatic investments of at least $100 a month until reaching the fund minimum. Investors opening accounts through financial intermediaries may open an account with $250 for Investor, A and R Classes, but the financial intermediaries may require their clients to meet different investment minimums. The minimum may be waived for broker-dealer sponsored wrap program accounts, fee based accounts, and accounts through bank/trust and wealth management advisory organizations.

The minimum initial investment amount for I Class is generally $5 million ($3 million for endowments and foundations), but the minimum may be waived if you have an aggregate investment in the American Century family of funds of $10 million or more ($5 million for endowments and foundations). This includes accounts held directly with American Century and those held through a financial intermediary.

There is no minimum initial investment amount for R6 Class shares.

For all share classes, there is no minimum initial investment amount for certain employer-sponsored retirement plans, however, financial intermediaries or plan recordkeepers may require plans to meet different minimums. There is a $50 minimum for subsequent purchases, except that there is no subsequent purchase minimum for financial intermediaries or employer-sponsored retirement plans.

**Tax Information**

Fund distributions are generally taxable as ordinary income or capital gains, unless you are investing through a tax-deferred account such as a 401(k) or individual retirement account (in which case you may be taxed upon withdrawal of your investment from such account).

**Payments to Broker-Dealers and Other Financial Intermediaries**

If you purchase the fund through a broker-dealer or other financial intermediary (such as a bank, insurance company, plan sponsor or financial professional), the fund and its related companies may pay the intermediary for the sale of fund shares and related services in

all classes except the R6 Class. These payments may create a conflict of interest by influencing the broker-dealer or other intermediary and your salesperson to recommend the fund over another investment. Ask your salesperson or visit your financial intermediary's website for more information.

**Example**

The example below is intended to help you compare the costs of investing in the fund with the costs 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 all of your shares at the end of those periods, that you earn 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* | *5 years* | *10 years* |
| Investor Class | $60 | $189 | $330 | $738 |
| I Class | $40 | $126 | $219 | $493 |
| A Class | $656 | $828 | $1015 | $1553 |
| R Class | $111 | $347 | $602 | $1329 |
| R6 Class | $25 | $77 | $135 | $306 |

**Portfolio Turnover**

Because the fund buys and sells shares of other American Century mutual funds directly from the issuers, the fund is not expected to incur transaction costs directly other than transaction costs associated with purchasing exchange-traded funds. However, as a shareholder in the underlying mutual funds, the fund indirectly pays transaction costs, such as commissions, when the underlying mutual funds buy and sell securities (or "turn over" their portfolios). 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 performance. During the most recent fiscal year, the fund's portfolio turnover rate was [22%] of the average value of its portfolio.

**Principal Investment Strategies**

One Choice Blend+ 2060 Portfolio is a "fund of funds," meaning that it seeks to achieve its objective by investing in other mutual funds advised by American Century (collectively, the underlying funds) that represent a variety of asset classes and investment styles. The underlying stock funds draw on growth, value and quantitative investment techniques and diversify investments among small, medium and large U.S. and foreign companies. The underlying bond funds invest in fixed-income securities that vary by issuer type (corporate and government), credit quality (investment-grade and high-yield or "junk bonds") and geographic exposure (domestic and international). Short-term investments include underlying funds that invest in fixed-income or debt instruments and have a shorter-term weighted average duration, typically three years or less. The following table indicates the fund's neutral mix; that is, how the fund's investments generally will be allocated among the major asset classes as of the date of this prospectus.

---

| | | |
|:---|:---|:---|
| **Equity Securities (Stock Funds)** |  | &nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;**95.0%** |
| &nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;*U.S. Equity* | &nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;*65.1 %* |  |
| &nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;*International Equity* | &nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;*27.1 %* |  |

---

The target date in the fund name (2060) refers to the approximate year an investor plans to retire and likely would stop making new investments in the fund. The target date does not necessarily represent the specific year you expect to need your assets. It is intended only as a general guide and assumes a retirement age of 65. The fund may not be appropriate for an investor who plans to retire at or near the target date, but at an age well before or after 65. The fund is designed for investors who plan to withdraw the value of their account gradually after retirement. Over time, the fund's neutral mix will become more conservative by decreasing the allocation to stocks and increasing the allocation to bonds and short-term investments. The fund will reach its most conservative allocation approximately five years after the target date, at which point its neutral mix is expected to become fixed at 40% stock funds, 54% bond funds and 6% short-term funds. The following chart shows how the neutral mix is expected to change over time according to a predetermined glide path.

![glidepath12012024a.jpg](glidepath12012024a.jpg)

The portfolio managers regularly review the fund's allocations to determine whether rebalancing is appropriate. In order to better balance risks in changing market environments, the portfolio managers may make modest deviations from the neutral mix in light of prevailing market conditions. We reserve the right to modify the neutral mix and underlying funds from time to time should circumstances warrant a change.

**Principal Risks**

• **Allocation Risk** – The fund's performance and risks depend in part on the managers' skill in determining the fund's neutral mix, selecting and weighting the underlying funds, and implementing any deviations from the neutral mix. The managers' evaluations and assumptions regarding asset classes or underlying funds may differ from actual market conditions.

------

**• Fund of Funds Risks** – The fund's performance and risks reflect the performance and risks of the underlying American Century Investments funds in which it invests. The fund's investment in other American Century Investments funds may create a conflict of interest for the fund's advisor.

• **"Growth" and "Value" Style Risks** – The underlying funds represent a mix of investment styles, each of which has risks associated with it. Growth stocks can be volatile and may lack dividends that can cushion share prices during market declines. Value stocks may continue to be undervalued by the market for long periods of time.

• **Small- and Mid-Cap Stock Risks** – Stocks of smaller companies may be more volatile than larger-company stocks. Smaller companies may have limited financial resources, product lines and markets, and their securities may trade less frequently and in more limited volumes than the securities of larger companies, which could lead to higher transaction costs. To the extent an underlying fund invests in these companies, it may take on more risk.

• **Interest Rate Risk** – Generally, when interest rates rise, the value of an underlying fund's fixed-income securities will decline. The opposite is true when interest rates decline. Underlying funds with longer weighted average maturities are more sensitive to interest rate changes. A period of rising interest rates may negatively affect the performance of underlying fixed-income funds.

• **Credit Risk** – The value of an underlying fund's fixed-income securities will be affected adversely by any erosion in the ability of the issuers of these securities to make interest and principal payments as they become due. Changes in the credit rating of a fixed-income security held by an underlying fund could have a similar effect.

• **Foreign Securities Risk** – Some of the underlying funds invest in foreign securities, which are generally riskier than U.S. securities. Political events, social and economic events, natural disasters and public health emergencies occurring in a country where the fund invests could cause the fund's investments in that country to experience gains or losses. Securities of foreign issuers may be less liquid, more volatile and harder to value than U.S. securities. Fluctuations in currency exchange rates also may affect an underlying fund's share price.

• **Emerging Market Risk** - Investing in securities of companies located in emerging market countries generally is also riskier than investing in securities of companies located in foreign developed countries. Emerging market countries may have unstable governments and/or economies that are subject to sudden change. These changes may be magnified by the countries' emergent financial markets, resulting in significant volatility to investments in these countries.

**• Market Risk** – The value of the fund's shares will go up and down based on the performance of the underlying funds in which it invests. The value of the underlying funds' shares will, in turn, fluctuate based on the performance of the securities they own and other factors generally affecting the securities market. Market risks, including political, regulatory, economic and social developments, can affect the value of the fund's investments. Natural disasters, public health emergencies, war, terrorism and other unforeseeable events may lead to increased market volatility and may have adverse long-term effects on world economies and markets generally.

• **Principal Loss Risk** – At any given time your shares may be worth less than the price you paid for them. In other words, it is possible to lose money by investing in the fund, including losses near to, at, or after retirement. There is no guarantee that the fund will provide adequate income at or through your retirement.

An investment in the fund is not a bank deposit, and it is not insured or guaranteed by the Federal Deposit Insurance Corporation (FDIC) or any other government agency.

**Fund Performance** 

The following bar chart and table provide some indication of the risks of investing in the fund. The bar chart shows changes in the fund's performance from year to year for Investor Class shares. The table shows how the fund's average annual returns for the periods shown compared with those of broad measures of market performance. The table also shows returns for the S&P Target Date to 2060 Index, which the advisor considers to be more representative of the fund's investment strategy. The fund's past performance (before and after taxes) is not necessarily an indication of how the fund will perform in the future. For current performance information, including yields, please visit americancentury.com.

Sales charges and account fees, if applicable, are not reflected in the bar chart. If those charges were included, returns would be less than those shown.

The after-tax returns are shown only for Investor Class shares. After-tax returns for other share classes will vary. After-tax returns are calculated using the historical highest individual federal marginal income tax rates and do not reflect the impact of state and local taxes. Actual after-tax returns depend on an investor's tax situation and may differ from those shown. After-tax returns are not relevant to investors who hold their fund shares through tax-deferred arrangements, such as 401(k) plans or IRAs.

**Example**

The example below is intended to help you compare the costs of investing in the fund with the costs 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 all of your shares at the end of those periods, that you earn 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* | *5 years* | *10 years* |
| Investor Class | $60 | $189 | $330 | $738 |
| I Class | $40 | $126 | $219 | $493 |
| A Class | $656 | $828 | $1015 | $1553 |
| R Class | $111 | $347 | $602 | $1329 |
| R6 Class | $25 | $77 | $135 | $306 |

---

**Portfolio Turnover**

Because the fund buys and sells shares of other American Century mutual funds directly from the issuers, the fund is not expected to incur transaction costs directly other than transaction costs associated with purchasing exchange-traded funds. However, as a shareholder in the underlying mutual funds, the fund indirectly pays transaction costs, such as commissions, when the underlying mutual funds buy and sell securities (or "turn over" their portfolios). 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 performance. During the most recent fiscal year, the fund's portfolio turnover rate was [17%] of the average value of its portfolio.

The target date in the fund name (2065) refers to the approximate year an investor plans to retire and likely would stop making new investments in the fund. The target date does not necessarily represent the specific year you expect to need your assets. It is intended only as a general guide and assumes a retirement age of 65. The fund may not be appropriate for an investor who plans to retire at or near the target date, but at an age well before or after 65. The fund is designed for investors who plan to withdraw the value of their account gradually after retirement. Over time, the fund's neutral mix will become more conservative by decreasing the allocation to stocks and increasing the allocation to bonds and short-term investments. The fund will reach its most conservative allocation approximately five years after the target date, at which point its neutral mix is expected to become fixed at 40% stock funds, 54% bond funds and 6% short-term funds. The following chart shows how the neutral mix is expected to change over time according to a predetermined glide path.

![glidepath12012024a.jpg](glidepath12012024a.jpg)

The portfolio managers regularly review the fund's allocations to determine whether rebalancing is appropriate. In order to better balance risks in changing market environments, the portfolio managers may make modest deviations from the neutral mix in light of prevailing market conditions. We reserve the right to modify the neutral mix and underlying funds from time to time should circumstances warrant a change.

**Principal Risks**

• **Allocation Risk** – The fund's performance and risks depend in part on the managers' skill in determining the fund's neutral mix, selecting and weighting the underlying funds, and implementing any deviations from the neutral mix. The managers' evaluations and assumptions regarding asset classes or underlying funds may differ from actual market conditions.

**• Fund of Funds Risks** – The fund's performance and risks reflect the performance and risks of the underlying American Century Investments funds in which it invests. The fund's investment in other American Century Investments funds may create a conflict of interest for the fund's advisor.

• **"Growth" and "Value" Style Risks** – The underlying funds represent a mix of investment styles, each of which has risks associated with it. Growth stocks can be volatile and may lack dividends that can cushion share prices during market declines. Value stocks may continue to be undervalued by the market for long periods of time.

• **Small- and Mid-Cap Stock Risks** – Stocks of smaller companies may be more volatile than larger-company stocks. Smaller companies may have limited financial resources, product lines and markets, and their securities may trade less frequently and in more limited volumes than the securities of larger companies, which could lead to higher transaction costs. To the extent an underlying fund invests in these companies, it may take on more risk.

• **Interest Rate Risk** – Generally, when interest rates rise, the value of an underlying fund's fixed-income securities will decline. The opposite is true when interest rates decline. Underlying funds with longer weighted average maturities are more sensitive to interest rate changes. A period of rising interest rates may negatively affect the performance of underlying fixed-income funds.

• **Credit Risk** – The value of an underlying fund's fixed-income securities will be affected adversely by any erosion in the ability of the issuers of these securities to make interest and principal payments as they become due. Changes in the credit rating of a fixed-income security held by an underlying fund could have a similar effect.

• **Foreign Securities Risk** – Some of the underlying funds invest in foreign securities, which are generally riskier than U.S. securities. Political events, social and economic events, natural disasters and public health emergencies occurring in a country where the fund invests could cause the fund's investments in that country to experience gains or losses. Securities of foreign issuers may be less liquid, more volatile and harder to value than U.S. securities. Fluctuations in currency exchange rates also may affect an underlying fund's share price.

• **Emerging Market Risk** - Investing in securities of companies located in emerging market countries generally is also riskier than investing in securities of companies located in foreign developed countries. Emerging market countries may have unstable governments and/or economies that are subject to sudden change. These changes may be magnified by the countries' emergent financial markets, resulting in significant volatility to investments in these countries.

**• Market Risk** – The value of the fund's shares will go up and down based on the performance of the underlying funds in which it invests. The value of the underlying funds' shares will, in turn, fluctuate based on the performance of the securities they own and other factors generally affecting the securities market. Market risks, including political, regulatory, economic and social developments, can affect the value of the fund's investments. Natural disasters, public health emergencies, war, terrorism and other unforeseeable events may lead to increased market volatility and may have adverse long-term effects on world economies and markets generally.

• **Principal Loss Risk** – At any given time your shares may be worth less than the price you paid for them. In other words, it is possible to lose money by investing in the fund, including losses near to, at, or after retirement. There is no guarantee that the fund will provide adequate income at or through your retirement.

An investment in the fund is not a bank deposit, and it is not insured or guaranteed by the Federal Deposit Insurance Corporation (FDIC) or any other government agency.

**Fund Performance** 

The following bar chart and table provide some indication of the risks of investing in the fund. The bar chart shows changes in the fund's performance from year to year for Investor Class shares. The table shows how the fund's average annual returns for the periods shown compared with those of broad measures of market performance. The table also shows returns for the S&P Target Date to 2065+ Index, which the advisor considers to be more representative of the fund's investment strategy. The fund's past performance (before and after taxes) is not necessarily an indication of how the fund will perform in the future. For current performance information, including yields, please visit americancentury.com.

Sales charges and account fees, if applicable, are not reflected in the bar chart. If those charges were included, returns would be less than those shown.

The after-tax returns are shown only for Investor Class shares. After-tax returns for other share classes will vary. After-tax returns are calculated using the historical highest individual federal marginal income tax rates and do not reflect the impact of state and local taxes. Actual after-tax returns depend on an investor's tax situation and may differ from those shown. After-tax returns are not relevant to investors who hold their fund shares through tax-deferred arrangements, such as 401(k) plans or IRAs.

You may purchase or redeem shares of the fund on any business day through our website at americancentury.com, in person (at one of our Investor Centers), by mail (American Century Investments, P.O. Box 419200, Kansas City, MO 64141-6200), by telephone at 1-800-345-2021 (Investor Services Representative) or 1-800-345-3533 (Business, Not-For-Profit and Employer-Sponsored Retirement Plans), or through a financial intermediary.

Unless otherwise specified below, the minimum initial investment amount to open an account is $2,500 ($1,000 for Coverdell Education Savings Accounts and IRAs).

The minimum initial investment amount for I Class is generally $5 million ($3 million for endowments and foundations), but the minimum may be waived if you have an aggregate investment in the American Century family of funds of $10 million or more ($5 million for endowments and foundations). This includes accounts held directly with American Century and those held through a financial intermediary.

There is no minimum initial investment amount for R6 Class shares.

For all share classes, there is no minimum initial investment amount for certain employer-sponsored retirement plans, however, financial intermediaries or plan recordkeepers may require plans to meet different minimums. There is a $50 minimum for subsequent purchases, except that there is no subsequent purchase minimum for financial intermediaries or employer-sponsored retirement plans.

**Tax Information**

Fund distributions are generally taxable as ordinary income or capital gains, unless you are investing through a tax-deferred account such as a 401(k) or individual retirement account (in which case you may be taxed upon withdrawal of your investment from such account).

**Payments to Broker-Dealers and Other Financial Intermediaries**

If you purchase the fund through a broker-dealer or other financial intermediary (such as a bank, insurance company, plan sponsor or financial professional), the fund and its related companies may pay the intermediary for the sale of fund shares and related services in all classes except the R6 Class. These payments may create a conflict of interest by influencing the broker-dealer or other intermediary and your salesperson to recommend the fund over another investment. Ask your salesperson or visit your financial intermediary's website for more information.

**Example**

The example below is intended to help you compare the costs of investing in the fund with the costs 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 all of your shares at the end of those periods, that you earn 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* | *5 years* | *10 years* |
| Investor Class | $60 | $189 | $330 | $738 |
| I Class | $40 | $126 | $219 | $493 |
| A Class | $656 | $828 | $1015 | $1553 |
| R Class | $111 | $347 | $602 | $1329 |
| R6 Class | $25 | $77 | $135 | $306 |

---

**Portfolio Turnover**

Because the fund buys and sells shares of other American Century mutual funds directly from the issuers, the fund is not expected to incur transaction costs directly other than transaction costs associated with purchasing exchange-traded funds. However, as a shareholder in the underlying mutual funds, the fund indirectly pays transaction costs, such as commissions, when the underlying mutual funds buy and sell securities (or "turn over" their portfolios). 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 performance. Because the fund is new, the fund's portfolio turnover rate is not available.

**Principal Investment Strategies**

One Choice Blend+ 2070 Portfolio is a "fund of funds," meaning that it seeks to achieve its objective by investing in other mutual funds advised by American Century (collectively, the underlying funds) that represent a variety of asset classes and investment styles. The underlying stock funds draw on growth, value and quantitative investment techniques and diversify investments among small, medium and large U.S. and foreign companies. The underlying bond funds invest in fixed-income securities that vary by issuer type (corporate and government), credit quality (investment-grade and high-yield or "junk bonds") and geographic exposure (domestic and international). Short-term investments include underlying funds that invest in fixed-income or debt instruments and have a shorter-term weighted average duration, typically three years or less. The following table indicates the fund's neutral mix; that is, how the fund's investments generally will be allocated among the major asset classes as of the date of this prospectus.

---

| | | |
|:---|:---|:---|
| **Equity Securities (Stock Funds)** |  | &nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;**95.0%** |
| &nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;*U.S. Equity* | &nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;*65.1 %* |  |
| &nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;*International Equity* | &nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;*27.1 %* |  |
| &nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;*Real Estate* | &nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;*2.8 %* |  |
| **Fixed-Income Securities (Bond Funds)** |  | &nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;**5.0%** |
| **Short-Term Investments (Short-Term Funds)** |  | &nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;**0.0%** |

---

The target date in the fund name (2070) refers to the approximate year an investor plans to retire and likely would stop making new investments in the fund. The target date does not necessarily represent the specific year you expect to need your assets. It is intended only as a general guide and assumes a retirement age of 65. The fund may not be appropriate for an investor who plans to retire at or near the target date, but at an age well before or after 65. The fund is designed for investors who plan to withdraw the value of their account gradually after retirement. Over time, the fund's neutral mix will become more conservative by decreasing the allocation to stocks and increasing the allocation to bonds and short-term investments. The fund will reach its most conservative allocation approximately five years after the target date, at which point its neutral mix is expected to become fixed at 40% stock funds, 54% bond funds and 6% short-term funds. The following chart shows how the neutral mix is expected to change over time according to a predetermined glide path.

![glidepath12012024a.jpg](glidepath12012024a.jpg)

The portfolio managers regularly review the fund's allocations to determine whether rebalancing is appropriate. In order to better balance risks in changing market environments, the portfolio managers may make modest deviations from the neutral mix in light of prevailing market conditions. We reserve the right to modify the neutral mix and underlying funds from time to time should circumstances warrant a change.

**Principal Risks**

• **Allocation Risk** – The fund's performance and risks depend in part on the managers' skill in determining the fund's neutral mix, selecting and weighting the underlying funds, and implementing any deviations from the neutral mix. The managers' evaluations and assumptions regarding asset classes or underlying funds may differ from actual market conditions.

------

**•** **Fund of Funds Risks** – The fund's performance and risks reflect the performance and risks of the underlying American Century Investments funds in which it invests. The fund's investment in other American Century Investments funds may create a conflict of interest for the fund's advisor.

• **"Growth" and "Value" Style Risks** – The underlying funds represent a mix of investment styles, each of which has risks associated with it. Growth stocks can be volatile and may lack dividends that can cushion share prices during market declines. Value stocks may continue to be undervalued by the market for long periods of time.

• **Small- and Mid-Cap Stock Risks** – Stocks of smaller companies may be more volatile than larger-company stocks. Smaller companies may have limited financial resources, product lines and markets, and their securities may trade less frequently and in more limited volumes than the securities of larger companies, which could lead to higher transaction costs. To the extent an underlying fund invests in these companies, it may take on more risk.

• **Interest Rate Risk** – Generally, when interest rates rise, the value of an underlying fund's fixed-income securities will decline. The opposite is true when interest rates decline. Underlying funds with longer weighted average maturities are more sensitive to interest rate changes. A period of rising interest rates may negatively affect the performance of underlying fixed-income funds.

• **Credit Risk** – The value of an underlying fund's fixed-income securities will be affected adversely by any erosion in the ability of the issuers of these securities to make interest and principal payments as they become due. Changes in the credit rating of a fixed-income security held by an underlying fund could have a similar effect.

• **Foreign Securities Risk** – Some of the underlying funds invest in foreign securities, which are generally riskier than U.S. securities. Political events, social and economic events, natural disasters and public health emergencies occurring in a country where the fund invests could cause the fund's investments in that country to experience gains or losses. Securities of foreign issuers may be less liquid, more volatile and harder to value than U.S. securities. Fluctuations in currency exchange rates also may affect an underlying fund's share price.

• **Emerging Market Risk** - Investing in securities of companies located in emerging market countries generally is also riskier than investing in securities of companies located in foreign developed countries. Emerging market countries may have unstable governments and/or economies that are subject to sudden change. These changes may be magnified by the countries' emergent financial markets, resulting in significant volatility to investments in these countries.

**•** **Market Risk** – The value of the fund's shares will go up and down based on the performance of the underlying funds in which it invests. The value of the underlying funds' shares will, in turn, fluctuate based on the performance of the securities they own and other factors generally affecting the securities market. Market risks, including political, regulatory, economic and social developments, can affect the value of the fund's investments. Natural disasters, public health emergencies, war, terrorism and other unforeseeable events may lead to increased market volatility and may have adverse long-term effects on world economies and markets generally.

• **Principal Loss Risk** – At any given time your shares may be worth less than the price you paid for them. In other words, it is possible to lose money by investing in the fund, including losses near to, at, or after retirement. There is no guarantee that the fund will provide adequate income at or through your retirement.

An investment in the fund is not a bank deposit, and it is not insured or guaranteed by the Federal Deposit Insurance Corporation (FDIC) or any other government agency.

**Fund Performance** 

Because the fund is new, the fund does not have performance history as of the date of this prospectus. When the fund has investment results for a full calendar year, this section will feature charts that show annual total returns, highest and lowest quarterly returns and average annual total returns for the fund. This information indicates the volatility of the fund's historical returns from year to year.

Performance information is designed to help you see how fund returns can vary. Keep in mind that past performance (before and after taxes) does not predict how the fund will perform in the future.

**Objectives, Strategies and Risks**

**What are the funds' investment objectives?** 

Each of One Choice Blend+ In Retirement, 2025, 2030, 2035, 2040, 2045, 2050, 2055, 2060, and 2065 Portfolios seeks the highest ***total return*** consistent with its asset mix.

***Total return*** *includes capital appreciation plus dividend and interest income.*<br>

Each Portfolio's objective is a nonfundamental investment policy and may be changed by the Board of Directors without shareholder approval upon 60 days' notice to the shareholders.

**What are the funds' principal investment strategies?**

Each fund invests in a combination of underlying funds advised by American Century Investments. Each fund's neutral mix is intended to diversify investments among various asset classes such as stocks, bonds and short-term investments. The neutral mix for One Choice Blend+ In Retirement Portfolio is expected to remain fixed over time. For each fund with a target date, the neutral mix will be adjusted in a step-like fashion. For example, assume the current stock weighting in One Choice Blend+ 2035 Portfolio is approximately 63.7% and the stock weighting in One Choice Blend+ 2030 Portfolio is approximately 55%. Over time, we would expect to reduce the stock weighting in One Choice Blend+ 2035 Portfolio. Over a five year period the stock weighting would be reduced to approximately 55%. In effect, One Choice Blend+ 2035 Portfolio is expected to have the same stock weighting in five years as One Choice Blend+ 2030 Portfolio has now. Each fund's neutral mix will continue to become more conservative until five years after its target date, at which point the fund's allocations will become fixed. By the time each fund reaches its target date, its neutral mix will become fixed and will match that of One Choice Blend+ In Retirement Portfolio, which is currently fixed at 40% stock funds, 54% bond funds and 6% short-term funds.

A fund with an earlier target date represents a more conservative choice. A fund with a later target date represents a more aggressive choice. The target date does not necessarily represent the specific year you expect to need your assets. It is intended only as a general guide and assumes a retirement age of 65.

The following table shows each fund's neutral mix as of the date of this prospectus.

In order to better balance risks in changing market environments, the portfolio managers may make modest deviations from the neutral mix in light of prevailing market conditions. We reserve the right to modify the neutral mix and underlying funds from time to time should circumstances warrant a change.

The portfolio managers regularly review each fund to determine whether rebalancing is appropriate.

A description of the policies and procedures with respect to the disclosure of the funds' portfolio securities is available in the statement of additional information.

**What are the underlying funds' investment techniques?**

The underlying stock funds draw on growth, value and quantitative investment techniques and diversify investments among small, medium and large U.S. companies. They also include investments in the real estate sector as well as foreign stocks from developed and emerging markets.

The growth strategy looks for stocks of companies the portfolio managers believe will increase in value over time. In implementing this strategy, the portfolio managers use a variety of analytical research tools and techniques to identify stocks of companies demonstrating accelerating earnings or revenue growth rates, stock price momentum, increasing cash flows, or other indications of the relative strength of a company's business. The value investment discipline seeks capital growth by investing in equity securities of companies that the funds' portfolio managers believe to be temporarily undervalued. For underlying funds that are quantitatively managed, the managers utilize quantitative, computer-driven models to construct and manage portfolios that they believe provide the optimal balance between risk and expected return.

The underlying bond funds represent a diverse range of fixed-income investments that vary by issuer type (corporate and government), credit quality (investment-grade and high-yield or "junk bonds") and geographic exposure (domestic and international).

Short-term investments include underlying funds that invest in fixed-income or debt instruments and have a shorter-term weighted average duration, typically three years or less.

A brief description of the underlying funds follows. Each fund invests in some, but not necessarily all, of the underlying funds listed, and may also invest in other American Century or Avantis funds that are not listed. Each fund's full portfolio holdings are posted on americancentury.com on a quarterly basis. Additional details regarding the strategies and risks of the underlying funds are available in the statement of additional information and the underlying funds' prospectuses, which are available at americancentury.com or avantisinvestors.com.

**Short-Term Funds**

The fund invests in debt securities such as notes, bonds, commercial paper, mortgage- or asset backed securities, collateralized loan obligations, collateralized mortgage obligations, and U.S. Treasury securities. These securities may be payable in U.S. or foreign currencies.

**What are the principal risks of investing in the funds?**

Each fund's performance and risks depend in part on the managers' skill in determining the fund's neutral mix, selecting and weighting the underlying funds, and implementing any deviations from the neutral mix. There is a risk that the managers' evaluations and assumptions regarding asset classes or underlying funds may differ from actual market conditions.

Each fund's performance and risks reflect the performance and risks of the underlying mutual funds in which it invests. Some of these risks relate to investments in stocks. Others relate primarily to fixed-income or foreign investments. The degree to which the risks described below apply to a particular fund varies according to its asset allocation.

The fund may hold a significant percentage of the shares of an underlying fund. As a result, the fund's investments in an underlying American Century Investments fund may create a conflict of interest for the advisor.

------

Market performance tends to be cyclical. In the various cycles, certain investment styles, such as growth and value styles, may fall in and out of favor. If the market is not favoring an underlying fund's style, that fund's gains may not be as big as, or its losses may be bigger than, those of other equity funds using different investment styles.

Growth stocks are typically priced higher than other stocks, in relation to earnings and other measures, because investors believe they have more growth potential. This potential may or may not be realized. If the portfolio managers' assessment of a company's prospects for earnings or growth or how other investors will value the company's earnings growth is incorrect, the price of the company's stock may fall or fail to reach the value the managers have placed on it. Growth stock prices tend to fluctuate more dramatically than the overall stock market.

Similarly, if the market does not consider the individual stocks purchased by a value fund to be undervalued, the fund's shares may not rise as high as other funds and may in fact decline, even if stock prices generally are increasing.

Underlying funds that invest in mid-sized and smaller companies may be more volatile, and subject to greater short-term risk, than funds that invest in larger companies. Smaller companies may have limited financial resources, product lines and markets, and their securities may trade less frequently and in more limited volumes than the securities of larger companies. In addition, smaller companies may have less publicly available information.

The value of an underlying fund's ***fixed-income securities*** will be affected by rising or falling interest rates. Generally interest rates and the prices of debt securities move in opposite directions. When interest rates fall, the prices of most debt securities rise; when interest rates rise, prices fall. Funds with longer weighted maturities are more sensitive to interest rate changes. A period of rising interest rates may negatively affect the funds' performance.

***Fixed-income securities*** *are rated by nationally recognized securities rating organizations (SROs), such as Moody's and Standard & Poor's. Each SRO has its own system for classifying securities, but each tries to indicate a company's ability to make timely payments of interest and principal*.<br>

The value of an underlying fund's fixed-income securities also will be affected by the inability or perceived inability of the issuers of these securities to make payments of interest and principal as they become due.

The lowest-rated investment-grade bonds in which the underlying funds may invest contain some speculative characteristics. Having those bonds in the funds' portfolios means the funds' values may go down more if interest rates or other economic conditions change than if the funds contained only higher-rated bonds. In addition, higher-risk high-yield securities, which are below investment-grade and sometimes referred to as junk bonds, are considered to be predominantly speculative and are more likely to be negatively affected by changes in interest rates or other economic conditions.

Some of the underlying funds invest in foreign securities. Foreign investment involves additional risks, including fluctuations in currency exchange rates, less stable political and economic structures, reduced availability of public information, and lack of uniform financial reporting and regulatory practices similar to those that apply in the United States. These factors make investing in foreign securities generally riskier than investing in U.S. securities. Securities of foreign issuers may be less liquid, more volatile and harder to value than U.S. securities. Investing in securities of companies located in emerging market countries is also riskier than investing in securities of companies located in foreign developed countries.

Investing in securities of issuers located in emerging market countries generally is riskier than investing in securities of companies located in foreign developed countries. Emerging market countries may have unstable governments and/or economies that are subject to sudden change. These changes may be magnified by the countries' emergent financial markets, resulting in significant volatility to investments in these countries. These countries also may lack the legal, business and social framework to support securities markets.

The value of an underlying fund's shares depends on the value of the stocks and other securities it owns. The value of the individual securities a fund owns will go up and down, depending on the performance of the companies that issued them, general market and economic conditions, and investor confidence. Market risks, including political, regulatory, economic and social developments, can affect the value of the fund's investments. Natural disasters, public health emergencies, war, terrorism and other unforeseeable events may lead to increased market volatility and may have adverse long-term effects on world economies and markets generally.

These funds are intended for investors who seek a diversified investment whose asset mix becomes more conservative over time, and who are willing to accept the risks associated with the funds' multi-asset strategies.

A fund may need to sell securities at times it would not otherwise do so in order to meet shareholder redemption requests. A fund could experience a loss when selling securities, particularly if the redemption requests are unusually large or frequent, occur in times of overall market turmoil or declining pricing for the securities sold or when the securities the fund wishes to sell are illiquid. Selling securities to meet such redemption requests also may increase transaction costs and/or have tax consequences. To the extent that a large shareholder (including another account advised by the advisor, a fund of funds or 529 college savings plan) invests in a fund, the fund may experience relatively large redemptions as such shareholder reallocates its assets. Although the advisor seeks to minimize the impact of such transactions where possible, a fund's performance may be adversely affected.

------

At any given time your shares may be worth less than the price you paid for them. In other words, it is possible to lose money by investing in the funds, including losses near to, at, or after retirement. There is no guarantee that a fund will provide adequate income at or through your retirement.

------

**Management**

**Who manages the funds?** 

The Board of Directors, investment advisor and fund management team play key roles in the management of the funds.

**The Board of Directors**

The Board of Directors is responsible for overseeing the advisor's management and operations of the funds pursuant to the management agreement. In performing their duties, Board members receive detailed information about the funds and their advisor regularly throughout the year, and meet at least quarterly with management of the advisor to review reports about fund operations. The directors' role is to provide oversight and not to provide day-to-day management. More than three-fourths of the directors are independent of the funds' advisor. They are not employees, directors or officers of, and have no financial interest in, the advisor or any of its affiliated companies (other than as shareholders of American Century Investments funds), and they do not have any other affiliations, positions or relationships that would cause them to be considered "interested persons" under the Investment Company Act of 1940. The directors also serve in that capacity for many of the underlying funds.

**The Investment Advisor** 

The funds' investment advisor is American Century Investment Management, Inc. (the advisor). The advisor has been managing mutual funds since 1958 and is headquartered at 4500 Main Street, Kansas City, Missouri 64111.

The advisor is responsible for managing the investment portfolios of the funds and directing the purchase and sale of the underlying American Century Investments funds in which they invest. The advisor also arranges for transfer agency, custody and all other services necessary for the funds to operate. Additionally, the advisor is responsible for the selection and management of the underlying funds' portfolio investments.

For certain services it provides to each fund and the underlying funds, the advisor receives a unified management fee based on a percentage of the daily net assets of each class of shares of the fund. The amount of the fee is calculated daily and paid monthly in arrears. Out of that fee, the advisor pays all expenses of managing and operating that fund except brokerage expenses, taxes, interest, fees and expenses of the independent directors (including legal counsel fees), extraordinary expenses, and expenses incurred in connection with the provision of shareholder services and distribution services under a plan adopted pursuant to Rule 12b-1 under the Investment Company Act of 1940. The difference in unified management fees among the classes is a result of their separate arrangements for non-Rule 12b-1 shareholder services. It is not the result of any difference in advisory or custodial fees or other expenses related to the management of the fund's assets, which do not vary by class. For all classes other than the R6 Class, the advisor may pay unaffiliated third parties who provide recordkeeping and administrative services that would otherwise be performed by an affiliate of the advisor. Because One Choice Blend+ 2070 is new, it is not included in the table below.

**Investing Through a Financial Intermediary**

Each fund may be purchased by participants in employer-sponsored retirement plans or through ***financial intermediaries*** that provide various administrative and distribution services.

***Financial intermediaries*** *include banks, broker-dealers, insurance companies, plan sponsors and financial professionals*.<br>

Although each class of a fund's shares represents an interest in the same fund, each has a different cost structure, as described below. Which class is right for you depends on many factors, including how long you plan to hold the shares, how much you plan to invest, the fee structure of each class, and how you wish to compensate your financial professional for the services provided to you. Your financial professional can help you choose the option that is most appropriate.

**Investor Class**

Investor Class shares are available for purchase without sales charges or commissions but may be subject to account or transaction fees if purchased through financial intermediaries. These shares are available to investors in retail brokerage accounts, broker-dealer-sponsored fee-based advisory accounts, other advisory accounts where fees are charged, and employer-sponsored retirement plans.

**I Class**

I Class shares are available for purchase without sales charges or commissions by endowments, foundations, large institutional investors, employer-sponsored retirement plans and financial intermediaries.

**A Class** 

A Class shares are available for purchase through broker-dealers and other financial intermediaries. These shares carry an initial sales charge and an ongoing distribution and service (12b-1) fee that is used to compensate your financial professional. See *Calculation of Sales Charges* below for commission amounts received by financial professionals on the purchase of A Class shares. The sales charge decreases with the size of the purchase, and may be reduced or eliminated in certain situations. See *Reductions and Waivers of Sales Charges for A Class* and *CDSC Waivers* below for a full description of the breakpoints, reductions and waivers that may be available through financial intermediaries in certain types of accounts or products.

**R Class**

R Class shares do not carry a sales charge or commission, but they have an ongoing distribution and service (12b-1) fee. R Class shares are available for purchase through certain employer-sponsored retirement plans. R Class shares also may be available for certain other accounts through financial intermediaries who have an agreement with us to offer the R Class in certain products. Additionally, IRA accounts in R Class shares established through financial intermediaries prior to August 1, 2006, may make additional purchases. With respect to purchases through financial intermediaries, R Class shares are not available in the following types of employer-sponsored retirement plans: SEP IRAs, SIMPLE IRAs or SARSEPs, except that investors in such plans with accounts in R Class shares established prior to March 1, 2009, may make additional purchases, and certain intermediaries may have agreements with us to offer R Class shares in such plans as described above.

**R6 Class**

R6 Class shares are available for purchase without sales charges or commissions by participants in certain employer-sponsored retirement plans. R6 Class shares may be purchased or redeemed only through employer-sponsored retirement plans where a financial intermediary provides retirement recordkeeping services to plan participants.

**Calculation of Sales Charges**

The information regarding sales charges provided herein is included free of charge and in a clear and prominent format at americancentury.com in the *Investors Using Advisors* and *Investment Professionals* portions of the website. From the description of A Class shares, a hyperlink will take you directly to this disclosure.

The availability of the sales charge reductions and waivers discussed below will depend upon whether you purchase your shares directly from the fund or through a financial intermediary. Intermediaries may have different policies and procedures regarding the availability of these reductions or waivers. Please refer to *Appendix A* for information provided by certain financial intermediaries regarding their sales charge waiver or discount policies that are applicable to investors transacting in fund shares through such financial intermediary.

------

**A Class**

A Class shares are sold at their offering price, which is net asset value plus an initial sales charge. This sales charge varies depending on the amount of your investment, and is deducted from your purchase before it is invested. The sales charges and the amounts paid to your financial professional are:

---

| | | | |
|:---|:---|:---|:---|
| *Purchase Amount* | *Sales Charge as a %<br>of Offering Price* | *Sales Charge as a %<br>of Net Amount Invested* | *Dealer Commission<br>as a % of Offering Price* |
| Less than $50,000 | 5.75% | 6.10% | 5.00% |
| $50000 - $99999 | 4.75% | 4.99% | 4.00% |
| $100000 - $249999 | 3.75% | 3.90% | 3.25% |
| $250000 - $499999 | 2.50% | 2.56% | 2.00% |
| $500000 - $999999 | 2.00% | 2.04% | 1.75% |
| $1000000 - $3999999 | 0.00% | 0.00% | 1.00% |
| $4000000 - $9999999 | 0.00% | 0.00% | 0.50% |
| $10,000,000 or more | 0.00% | 0.00% | 0.25% |

---

There is no front-end sales charge for purchases of $1,000,000 or more, but if you redeem your shares within one year of purchase you will pay a deferred sales charge of 1.00% of the lower of the original purchase price or the current market value at redemption, subject to the exceptions listed below. No sales charge applies to reinvested dividends. No dealer commission will be paid to your financial professional for purchases by certain employer-sponsored retirement plans. For this purpose, employer-sponsored retirement plans do not include SEP IRAs, SIMPLE IRAs or SARSEPs.

**Reductions and Waivers of Sales Charges for A Class** 

You may qualify for a reduction or waiver of certain sales charges, but you or your financial professional must provide certain information, including the account numbers of any accounts to be aggregated, to American Century Investments at the time of purchase in order to take advantage of such reduction or waiver. If you hold assets among multiple intermediaries, it is your responsibility to inform your intermediary and/or American Century Investments at the time of purchase, of any accounts to be aggregated.

You and your immediate family (which includes your spouse or domestic partner and children, step-children, parents or step-parents of you, your spouse or domestic partner) may combine investments in any share class of any American Century Investments mutual fund (excluding certain assets in money market accounts, but including account assets invested in Qualified Tuition Programs under Section 529) to reduce your A Class sales charge in the following ways:

*Account Aggregation*. Investments made by you and your immediate family may be aggregated at each account's current market value if made for your own account(s) and/or certain other accounts, such as:

• Certain trust accounts

• Solely controlled business accounts

• Single-participant retirement plans

• Endowments or foundations established and controlled by you or an immediate family member

For purposes of aggregation, only investments made through individual-level accounts may be combined. Assets held in multiple participant employer-sponsored retirement plans may be aggregated at a plan level.

*Concurrent Purchases*. You may combine simultaneous purchases in any share class of any American Century Investments mutual fund to qualify for a reduced A Class sales charge.

*Rights of Accumulation.* You may take into account the current value of your existing holdings, less any commissionable shares in the money market funds, in any share class of any American Century Investments mutual fund to qualify for a reduced A Class sales charge. An investor who purchases fund shares through a financial intermediary may be subject to different rights of accumulation policies of such financial intermediary. Please consult with your financial professional for further details.

*Letter of Intent*. A Letter of Intent allows you to combine all purchases of any share class of any American Century Investments mutual fund you intend to make over a 13-month period to determine the applicable sales charge, except for purchases in the A Class of money market funds. At your request, existing holdings may be combined with new purchases and sales charge amounts may be adjusted for purchases made within 90 days prior to our receipt of the Letter of Intent. Capital appreciation, capital gains and reinvested dividends earned during the Letter of Intent period do not apply toward its completion. A portion of your account will be held in escrow to cover additional A Class sales charges that will be due if your total investments over the 13-month period do not qualify for the applicable sales charge reduction.

------

*Waivers for Certain Investors.* The sales charge on A Class shares may be waived for:

• Purchases by registered representatives and other employees of certain financial intermediaries (and their immediate family members, which includes their spouse or domestic partner and children or step-children, parents or step-parents of them, their spouse or domestic partner) having selling agreements with the advisor or distributor

• Broker-dealer sponsored wrap program accounts and/or fee-based accounts maintained for clients of certain financial intermediaries who have entered into selling agreements with American Century Investments

• Purchases in accounts of financial intermediaries that have entered into a selling agreement with American Century Investments that allows for the waiver of the sales charge in brokerage accounts that may or may not charge a transaction fee

• Current officers, directors or employees of American Century Investments

• Certain group employer-sponsored retirement plans, where plan level or omnibus accounts are held with the fund, or shares are purchased by certain retirement plans that are part of a retirement plan or platform offered by banks, broker-dealers, financial advisors or insurance companies, or serviced by retirement recordkeepers. For purposes of this waiver, employer-sponsored retirement plans do not include SEP IRAs, SIMPLE IRAs or SARSEPs. However, SEP IRA, SIMPLE IRA or SARSEP retirement plans that (i) held shares of an A Class fund prior to March 1, 2009 that received sales charge waivers or (ii) held shares of an Advisor Class fund that was renamed A Class on March 1, 2010, may permit additional purchases by new and existing participants in A Class shares without an initial sales charge. Refer to *Buying and Selling Fund Shares* in the statement of additional information

• Purchases of additional shares in accounts that held shares of an Advisor Class fund that was renamed A Class on either September 4, 2007, December 3, 2007 or March 1, 2010. However, if you close your account or if you transfer your account to another financial intermediary, future purchases of A Class shares of a fund may not receive a sales charge waiver.

An investor who receives a sales charge waiver for purchases of fund shares through a financial intermediary may become ineligible to receive such waiver if the nature of the investor's relationship with and/or the services it receives from the financial intermediary changes. Please consult with your financial professional for further details.

**Calculation of Contingent Deferred Sales Charge (CDSC)** 

To minimize the amount of the CDSC you may pay when you redeem shares, the fund will first redeem shares acquired through reinvested dividends and capital gain distributions, which are not subject to a CDSC. Shares that have been in your account long enough that they are not subject to a CDSC are redeemed next. For any remaining redemption amount, shares will be sold in the order they were purchased (earliest to latest).

**CDSC Waivers**

Any applicable CDSC for A Classes may be waived in the following cases:

• redemptions through systematic withdrawal plans not exceeding annually 12% of the lesser of the original purchase cost or current market value for A Class shares

• redemptions through employer-sponsored retirement plans. For this purpose, employer-sponsored retirement plans do not include SEP IRAs, SIMPLE IRAs or SARSEPs.

• distributions from IRAs due to attainment of age 59½ for A Class shares

• required minimum distributions from retirement accounts due to the shareholder reaching the qualified age based on applicable IRS regulations

• tax-free returns of excess contributions to IRAs

• redemptions due to death or post-purchase disability

• exchanges, unless the shares acquired by exchange are redeemed within the original CDSC period

• IRA Rollovers from any American Century Investments mutual fund held in an employer-sponsored retirement plan, for A Class shares only

• if no dealer commission was paid to the financial intermediary on the purchase for any other reason

**Reinstatement Privilege**

Within 90 days of a redemption, dividend payment or capital gains distribution of any A Class shares, you may reinvest all or a portion of the proceeds in A Class shares of any American Century Investments mutual fund at the then-current net asset value without paying an initial sales charge. At your request, any CDSC you paid on an A Class redemption that you are reinvesting will be credited to your account. You may use the privilege only once per account. This privilege may only be invoked by the original account owner to reinvest shares in an account with the same registration as the account from which the redemption or distribution originated. This privilege does not apply to systematic or automatic transactions, including, for example, automatic purchases, withdrawals and payroll

------

deductions. If you wish to use this reinvestment privilege, you or your financial professional must provide written notice to American Century Investments.

**Employer-Sponsored Retirement Plans**

Certain group employer-sponsored retirement plans that hold a single account for all plan participants with the fund, or that are part of a retirement plan or platform offered by banks, broker-dealers, financial advisors or insurance companies, or serviced by retirement recordkeepers are eligible to purchase Investor, I, A, R and R6 Class shares. For more information regarding employer-sponsored retirement plan types, please refer to *Buying and Selling Fund Shares* in the statement of additional information. A Class purchases are available at net asset value with no dealer commission paid to the financial professional, and do not incur a CDSC. A and R Class shares purchased in employer-sponsored retirement plans are subject to applicable distribution and service (12b-1) fees, which the financial intermediary begins receiving immediately at the time of purchase. American Century does not impose plan size or participant number requirements by class for employer-sponsored retirement plans; however, financial intermediaries or plan recordkeepers may require plans to meet different requirements.

**Exchanging Shares**

You may exchange shares of the fund for shares of the same class of another American Century Investments mutual fund without a sales charge if you meet the following criteria:

• The exchange is for a minimum of $100

• For an exchange that opens a new account, the amount of the exchange must meet or exceed the minimum account size requirement for the fund receiving the exchange

For purposes of computing any applicable CDSC on shares that have been exchanged, the holding period will begin as of the date of purchase of the original fund owned. Exchanges from a money market fund are subject to a sales charge on the fund being purchased, unless the money market fund shares were acquired by exchange from a fund with a sales charge or by reinvestment of dividends or capital gains distributions.

**Moving Between Share Classes and Accounts**

You may move your investment between share classes (within the same fund or between different funds) in certain circumstances deemed appropriate by American Century Investments. You also may move investments held in certain accounts to a different type of account if you meet certain criteria. Please contact your financial professional for more information about moving between share classes or account types.

**Buying and Selling Shares Through a Financial Intermediary**

Your ability to purchase, exchange, redeem and transfer shares will be affected by the policies of the financial intermediary through which you do business. Some policy differences may include

• minimum investment requirements

• exchange policies

• fund choices

• cutoff time for investments

• trading restrictions

In addition, your financial intermediary may charge a transaction fee for the purchase or sale of fund shares. Those charges are retained by the financial intermediary and are not shared with American Century Investments or the funds. Please contact your financial intermediary or plan sponsor for a complete description of its policies. Copies of the funds' annual report, semiannual report and statement of additional information are available from your financial intermediary or plan sponsor.

The funds have authorized certain financial intermediaries to accept orders on the funds' behalf. American Century Investments has selling agreements with these financial intermediaries requiring them to track the time investment orders are received and to comply with procedures relating to the transmission of orders. Orders must be received by the financial intermediary on the funds' behalf before the time the net asset value is determined in order to receive that day's share price. If those orders are transmitted to American Century Investments and paid for in accordance with the selling agreement, they will be priced at the net asset value next determined after your request is received in the form required by the financial intermediary.

If you submit a transaction request through a financial intermediary that does not have a selling agreement with us, or if the financial intermediary's selling agreement does not cover the type of account or share class requested, we may reject or cancel the transaction without prior notice to you or the intermediary.

Investor and I Class shares may also be available on brokerage platforms of financial intermediaries that have agreements with American Century Investments to offer such shares solely when acting as an agent for the shareholder. A shareholder transacting in

------

Investor or I Class shares in these programs may be required to pay a commission and/or other forms of compensation to the broker. Shares of the fund are available in other share classes that have different fees and expenses.

**See *Additional Policies Affecting Your Investment* for more information about investing with us.**

**Additional Policies Affecting Your Investment**

**Eligibility for Investor Class Shares**

The fund's Investor Class shares are available for purchase directly from American Century Investments and through the following types of products, programs or accounts offered by financial intermediaries:

• self-directed accounts on transaction-based platforms that may or may not charge a transaction fee

• employer-sponsored retirement plans

• broker-dealer sponsored fee-based wrap programs or other fee-based advisory accounts

• insurance products and bank/trust products where fees are being charged

The fund reserves the right, when in the judgment of American Century Investments it is not adverse to the fund's interest, to permit all or only certain types of investors to open new accounts in the fund, to impose further restrictions, or to close the fund to any additional investments, all without notice.

**Minimum Initial Investment Amounts for Investor, A and R Classes**

Unless otherwise specified below, the minimum initial investment amount to open an account is $2,500. However, American Century Investments will waive the fund minimum if you make an initial investment of at least $500 and continue to make automatic investments of at least $100 a month until reaching the fund minimum.

Investors opening accounts through financial intermediaries may open an account with $250, but the financial intermediaries may require their clients to meet different investment minimums. See *Investing Through a Financial Intermediary* for more information.

<sup>1</sup> *&nbsp;&nbsp;&nbsp;&nbsp;American Century Investments will waive the minimum if you make an initial investment of at least $500 and continue to make automatic investments of at least $100 a month until reaching the minimum.*

<sup>2</sup> *&nbsp;&nbsp;&nbsp;&nbsp;The minimum initial investment for shareholders investing through financial intermediaries is $250. Financial intermediaries may have different minimums for their clients.*

**Subsequent Purchases**

There is a $50 minimum for subsequent purchases. See *Ways to Manage Your Account* for more information about making additional investments directly with American Century Investments. However, there is no subsequent purchase minimum for financial intermediaries or employer-sponsored retirement plans, but financial intermediaries may require their clients to meet different subsequent purchase requirements.

**Eligibility for I Class Shares**

I Class shares are made available for purchase by individuals and large institutional shareholders such as bank trust departments, corporations, retirement plans, endowments, foundations and financial advisors that meet the funds' minimum investment requirements.

**Minimum Initial Investment Amounts for I Class**

The minimum initial investment amount for I Class shares is generally $5 million ($3 million for endowments and foundations) per fund. If you invest with us through a financial intermediary, this requirement may be met if your financial intermediary aggregates your investments with those of other clients into a single group, or omnibus, account that meets the minimum. The minimum investment requirement may be waived if you have an aggregate investment in the American Century family of funds of $10 million or more ($5 million for endowments and foundations). This includes accounts held directly with American Century and those held through a financial intermediary. American Century Investments also may waive the minimum initial investment in other situations it deems appropriate. In addition, there is no minimum investment amount for employer-sponsored retirement plans where a financial intermediary provides retirement recordkeeping services to plan participants and where plan level or omnibus accounts are held on the books of the fund. Financial intermediaries or plan recordkeepers may require plans to meet certain other conditions, such as plan size or minimum level of assets per participants, in order to be eligible to purchase I Class shares.

American Century Investments may permit an intermediary to waive the initial minimum per shareholder as provided in *Buying and Selling Fund Shares* in the statement of additional information.

------

**Eligibility for R6 Class Shares** 

The fund's R6 Class shares are generally available only through employer-sponsored retirement plans where a financial intermediary provides retirement recordkeeping services to plan participants. To be eligible, plan level or omnibus accounts must be held on the books of the fund.

R6 Class shares are not available to retail accounts, traditional or Roth IRAs, SEP IRAs, SIMPLE IRAs, SARSEPs or Coverdell education savings accounts.

**Minimum Initial Investment Amounts for R6 Class**

There is no minimum initial amount or subsequent investment amount for R6 Class shares, but financial intermediaries or plan recordkeepers may require plans to meet different investment minimums.

**Redemptions**

Your redemption proceeds will be calculated using the net asset value (NAV) next determined after we receive your transaction request in good order. If you sell A Class shares, you may pay a sales charge, depending on how long you have held your shares, as described above.

Generally, we expect to remit your redemption proceeds to you one business day after we process your transaction. However, we reserve the right to delay delivery of redemption proceeds for up to seven days. For example, each time you make an investment with American Century Investments, there is a seven-day holding period before we will release redemption proceeds from those shares, unless you provide us with satisfactory proof that your purchase funds have cleared. Investments by wire generally require only a one-day holding period. If you change your address, we may require that any redemption request made within seven days be submitted in writing and be signed by all authorized signers with their signatures guaranteed. We may also require a signature guarantee for redemptions in other situations, as described below. If you change your bank information, we may impose a seven-day holding period before we will transfer or wire redemption proceeds to your bank. Please remember, if you request redemptions by wire, $10 will be deducted from the amount redeemed. Your bank also may charge a fee.

Under normal market conditions, the fund generally meets redemption requests through its holdings of cash or cash equivalents or by selling portfolio securities. However, we reserve the right to honor certain redemptions with securities, rather than cash, as described in the next section. Additionally, the fund may consider interfund lending to meet redemption requests. The fund is more likely to use these other methods to meet large redemption requests or during times of market stress.

Additionally, if you are age 65 or older, or if we have reason to believe you have a mental or physical impairment that renders you unable to protect your own interest, we may temporarily delay the disbursement of redemption proceeds from your account if we believe that you have been the victim of actual or attempted financial exploitation. This temporary delay will be for an initial period of no more than 15 business days while we conduct an internal review of the facts and circumstances of the suspected financial exploitation. If our internal review supports our belief that actual or attempted financial exploitation has occurred or is occurring, we may extend the hold for up to 10 additional business days. At the expiration of the additional hold time, if we have not confirmed that exploitation has occurred, the proceeds will be released to you.

**Redemption of Shares in Accounts Below Minimum**

If your account balance falls below the minimum initial investment amount for any reason, or if you cancel your automatic monthly investment plan prior to reaching the fund minimum, American Century Investments reserves the right to redeem the shares in the account and send the proceeds to your address of record. Prior to doing so, we will notify you and give you 60 days to meet the minimum or reinstate your automatic monthly investment plan. Please note that A Class shares redeemed in this manner may be subject to a sales charge if held less than the applicable time period. You also may incur tax liability as a result of the redemption. For I Class shares, we reserve the right to convert your shares to Investor Class shares of the same fund. The total annual operating expenses of Investor Class shares are higher than I Class shares.

**Small Distributions and Uncashed Distribution Checks**

Generally, dividends and distributions cannot be paid by check for an amount less than $50. Any such amount will be automatically reinvested in additional shares. The fund reserves the right to reinvest any dividend or distribution amount you elect to receive by check if your check is returned as undeliverable or if you do not cash your check within six months. Interest will not accrue on the amount of your uncashed check. We will reinvest your check into your account at the NAV on the day of reinvestment. When reinvested, those amounts are subject to the risk of loss like any other fund investment. We also reserve the right to change your election to receive dividends and distributions in cash after a check is returned undeliverable or uncashed for the six month period, and we may automatically reinvest all future dividends and distributions at the NAV on the date of the payment.

------

**Signature Guarantees**

A signature guarantee — which is different from a notarized signature — is a warranty that the signature presented is genuine. We may require a signature guarantee for the following transactions:

• Your redemption or distribution check or automatic redemption is made payable to someone other than the account owners;

• Your redemption proceeds or distribution amount is sent by EFT (ACH or wire) to a destination other than your personal bank account;

• You are transferring ownership of an account over $100,000;

• You change your address and request a redemption over $100,000 within seven days;

• You request proceeds from redemptions, dividends, or distributions be sent to an address or financial institution differing from those on record; or

• You make a redemption or other transaction request via telephone, and we are unable to verify your identity.

We reserve the right to require a signature guarantee for other transactions, or we may employ other security measures, such as signature comparison or notarized signature, at our discretion.

**Canceling a Transaction**

American Century Investments will use its best efforts to honor your request to revoke a transaction instruction if your revocation request is received prior to the close of trading on the New York Stock Exchange (NYSE) (generally 4 p.m. Eastern time) on the trade date of the transaction. Once processing has begun, or the NYSE has closed on the trade date, the transaction can no longer be canceled. Each fund reserves the right to suspend the offering of shares for a period of time and to reject any specific investment (including a purchase by exchange). Additionally, we may refuse a purchase if, in our judgment, it is of a size that would disrupt the management of a fund.

**Frequent Trading Practices**

Because of the potentially harmful effects of abusive trading practices, the funds' Board of Directors has approved American Century Investments' abusive trading policies and procedures, which are designed to reduce the frequency and effect of these activities in our funds. These policies and procedures include monitoring trading activity, imposing trading restrictions on certain accounts, and using fair value pricing when current market prices are not readily available for securities held by the underlying funds. Although these efforts are designed to discourage abusive trading practices, they cannot eliminate the possibility that such activity will occur. American Century Investments seeks to exercise its judgment in implementing these tools to the best of its ability in a manner that it believes is consistent with shareholder interests.

American Century Investments uses a variety of techniques to monitor for and detect frequent trading practices. These techniques may vary depending on the type of fund, the class of shares or whether the shares are held directly or indirectly with American Century Investments. They may change from time to time as determined by American Century Investments in its sole discretion. To minimize harm to the funds and their shareholders, we reserve the right to reject any purchase order (including exchanges) from any shareholder we believe has a history of frequent trading or whose trading, in our judgment, has been or may be disruptive to the funds. In making this judgment, we may consider trading done in multiple accounts under common ownership or control.

Currently, for shares held directly with American Century Investments, we may deem the sale of all or a substantial portion of a shareholder's purchase of fund shares to be frequent trading if the sale is made

• within seven days of the purchase, or

• within 30 days of the purchase, if it happens more than once per year.

To the extent practicable, we try to use the same approach for defining frequent trading for shares held through financial intermediaries. American Century Investments reserves the right, in its sole discretion, to identify other trading practices as abusive and to modify its monitoring and other practices as necessary to deal with novel or unique abusive trading practices.

------

The frequent trading limitations do not apply to the following types of transactions:

• purchases of shares through reinvested distributions (dividends and capital gains);

• redemption of shares to pay fund or account fees;

• CheckWriting redemptions;

• redemptions requested following the death of a registered shareholder;

• transactions through automatic purchase or redemption plans;

• transfers and re-registrations of shares within the same fund;

• shares exchanged from one share class to another within the same fund;

• transactions by 529 college savings plans; and

• reallocation or rebalancing transactions in broker-dealer sponsored fee-based wrap and advisory programs.

For shares held in employer-sponsored retirement plans, generally only participant-directed exchange transactions are subject to the frequent trading restrictions. For this purpose, employer-sponsored retirement plans do not include SEP IRAs, SIMPLE IRAs, or SARSEPs.

In addition, American Century Investments reserves the right to accept purchases and exchanges in excess of the trading restrictions discussed above if it believes that such transactions would not be inconsistent with the best interests of fund shareholders or this policy.

American Century Investments' policies do not permit us to enter into arrangements with fund shareholders that permit such shareholders to engage in frequent purchases and redemptions of fund shares. Due to the complexity and subjectivity involved in identifying abusive trading activity and the volume of shareholder transactions American Century Investments handles, there can be no assurance that American Century Investments' efforts will identify all trades or trading practices that may be considered abusive. American Century Investments monitors aggregate trades placed in omnibus accounts and works with financial intermediaries to identify shareholders engaging in abusive trading practices and impose restrictions to discourage such practices. Because American Century Investments relies on financial intermediaries to provide information and impose restrictions, our ability to monitor and discourage abusive trading practices in omnibus accounts may be dependent upon the intermediaries' timely performance of such duties and restrictions may not be applied uniformly in all cases.

**Your Responsibility for Unauthorized Transactions**

American Century Investments and its affiliated companies use procedures reasonably designed to confirm that telephone, electronic and other instructions are genuine. These procedures include recording telephone calls, requesting additional identifying information, requiring personalized security codes or other information online, and sending confirmation of transactions. If we follow these procedures, we are not responsible for any losses that may occur due to unauthorized instructions. For transactions conducted over the Internet, we recommend the use of a secure Internet browser. In addition, you should verify the accuracy of your confirmation statements immediately after you receive them.

**A Note About Mailings to Shareholders**

To reduce the amount of mail you receive from us, we generally deliver a single copy of fund documents (like shareholder reports, proxies and prospectuses) to investors who share an address, even if their accounts are registered under different names. Investors who share an address may also receive account-specific documents (like statements) in a single envelope. If you prefer to receive your documents addressed individually, please call us or your financial professional. For American Century Investments brokerage accounts, please call 1-888-345-2071.

**Right to Change Policies**

We reserve the right to change any stated investment requirement, including those that relate to purchases, exchanges and redemptions. In accordance with applicable law, we also may alter, add or discontinue any service or privilege. Changes may affect all investors or only those in certain classes or groups. In addition, from time to time we may waive a policy on a case-by-case basis, as the advisor deems appropriate.

------

**Share Price and Distributions**

**Share Price** 

American Century Investments will price the fund shares you purchase, exchange or redeem based on the ***net asset value*** (NAV) next determined after your order is received in good order by the fund's transfer agent, or other financial intermediary with the authority to accept orders on the fund's behalf. We determine the NAV of each fund as of the close of regular trading (usually 4 p.m. Eastern time) on the New York Stock Exchange (NYSE) on each day the NYSE is open. On days when the NYSE is closed (including certain U.S. national holidays), we do not calculate the NAV.

*The* ***net asset value****, or NAV, of each class of a fund is the current value of the class's assets, minus any liabilities, divided by the number of shares of the class outstanding.* <br>

The value of the securities and other assets and liabilities held by the fund are determined by the advisor, as the valuation designee, pursuant to its valuation policies and procedures. The fund's Board of Directors oversees the valuation designee and at least annually reviews its valuation policies and procedures. Valuations are determined in accordance with applicable federal securities laws and accounting principles generally accepted in the United States.

With respect to the portion of each fund's assets that are invested in underlying mutual funds, the fund's NAV is calculated based upon the NAVs of such underlying mutual funds. The prospectuses for the underlying mutual funds explain the methods used to value underlying fund shares, including the circumstances under which those funds may use fair value pricing and the effects of doing so.

Portfolio securities for which market quotations are readily available are valued at their market price. If the fund invests in ETFs, such ETFs are valued at the last reported official closing price or sale price at the time the NAV is determined.

If the valuation designee determines that the market price for a portfolio security is not readily available or is believed by the valuation designee to be unreliable, such security is valued at fair value as determined in good faith by the valuation designee, in accordance with its policies and procedures. A circumstance that may cause the fund to determine that market quotations are not available or reliable includes, but is not limited to, trading in a security has been halted during the trading day.

If such circumstances occur, the valuation designee will fair value the security if the fair valuation would materially impact the fund's NAV. While fair value determinations involve judgments that are inherently subjective, these determinations are made in good faith in accordance with the valuation designee's policies and procedures.

The effect of using fair value determinations is that the fund's NAV will be based, to some degree, on security valuations that the valuation designee reasonably believes are fair rather than being solely determined by the market.

Trading in foreign markets of securities that are held by the underlying funds may not take place every day the NYSE is open. Also, trading in some foreign markets and on some electronic trading networks may take place on weekends or holidays when the underlying funds' NAVs are not calculated. So, the value of the underlying funds' portfolios and consequently the funds' portfolios may be affected on days when you will not be able to purchase, exchange or redeem fund shares.

**Distributions**

Federal tax laws require each fund to make distributions to its shareholders in order to qualify as a regulated investment company. Qualification as a regulated investment company means that the funds should not be subject to state or federal income tax on amounts distributed. The distributions generally consist of dividends and interest received by the fund, as well as ***capital gains*** realized by the fund on the sale of its investment securities.

***Capital gains*** *are increases in the values of capital assets, such as stocks or bonds, from the time the assets are purchased.*<br>

The funds generally expect to pay distributions from net income and capital gains, if any, once a year in December. The funds may make more frequent distributions, if necessary, to comply with Internal Revenue Code provisions.

You will participate in fund distributions when they are declared, starting the next business day after your purchase is effective. For example, if you purchase shares on a day that a distribution is declared, you will not receive that distribution. If you redeem shares, you will receive any distribution declared on the day you redeem. If you redeem all shares, we will include any distributions received with your redemption proceeds.

Generally, participants in tax-deferred retirement plans reinvest all distributions. For investors investing through taxable accounts, we will reinvest distributions unless you elect to have dividends and/or capital gains sent to another American Century Investments account, to your bank electronically, or to your home address or to another person or address by check.

------

**Taxes** 

Some of the tax consequences of owning shares of the funds will vary depending on whether you own them through a taxable or tax-deferred account. Distributions by the funds of dividend and interest income, capital gains and other income they have generated through their investment activities, will generally be taxable to shareholders who hold shares in a taxable account. Tax consequences also may result when investors sell fund shares after the net asset value has increased or decreased.

**Tax-Deferred Accounts**

If you purchase fund shares through a tax-deferred account, such as an IRA or employer-sponsored retirement plan, income and capital gains distributions usually will not be subject to current taxation but will accumulate in your account under the plan on a tax-deferred basis. Likewise, moving from one fund to another fund within a plan or tax-deferred account generally will not cause you to be taxed. For information about the tax consequences of making purchases or withdrawals through a tax-deferred account, please consult your plan administrator, your summary plan description or a tax advisor.

**Taxable Accounts**

If you own fund shares through a taxable account, you may be taxed on your investments if the fund makes distributions or if you sell your fund shares.

**Taxability of Distributions**

Fund distributions may consist of income, such as dividends and interest earned by a fund from its investments, or capital gains generated by a fund from the sale of investment securities. Distributions of income are taxed as ordinary income, unless they are designated as ***qualified dividend income*** and you meet a minimum required holding period with respect to your shares of the fund, in which case distributions of income are taxed at the same rates as long-term capital gains.

***Qualified dividend income*** *is a dividend received by the fund from the stock of a domestic or qualifying foreign corporation, provided that the fund has held the stock for a required holding period and the stock was not on loan at the time of the dividend.*<br>

The tax character of any distributions from capital gains is determined by how long the fund held the underlying security that was sold, not by how long you have been invested in the fund or whether you reinvest your distributions or take them in cash. Short-term (one year or less) capital gains are taxable as ordinary income. Gains on securities held for more than one year are taxed at the lower rates applicable to long-term capital gains.

If the fund's distributions exceed current and accumulated earnings and profits, such excess will generally be considered a return of capital. A return of capital distribution is generally not subject to tax, but will reduce your cost basis in the fund and result in higher realized capital gains (or lower realized capital losses) upon the sale of fund shares.

For taxable accounts, American Century Investments or your financial intermediary will inform you of the tax character of fund distributions for each calendar year in an annual tax mailing.

If you meet specified income levels, you will also be subject to a 3.8% Medicare contribution tax which is imposed on net investment income, including interest, dividends and capital gains. Distributions also may be subject to state and local taxes. Because everyone's tax situation is unique, you may want to consult your tax professional about federal, state and local tax consequences.

**Taxes on Transactions** 

Your redemptions—including exchanges to other American Century Investments mutual funds—are subject to capital gains tax. Short-term capital gains are gains on fund shares you held for 12 months or less. Long-term capital gains are gains on fund shares you held for more than 12 months. If your shares decrease in value, their sale or exchange will result in a long-term or short-term capital loss. However, you should note that loss realized upon the sale or exchange of shares held for six months or less will be treated as a long-term capital loss to the extent of any distribution of long-term capital gain to you with respect to those shares. If a loss is realized on the redemption of fund shares, the reinvestment in additional fund shares within 30 days before or after the redemption may be subject to the wash sale rules of the Internal Revenue Code. This may result in a postponement of the recognition of such loss for federal income tax purposes.

If you have not certified to us that your Social Security number or tax identification number is correct and that you are not subject to withholding, we are required to withhold and pay to the IRS the applicable federal withholding tax rate on taxable dividends, capital gains distributions and redemption proceeds.

------

**Buying a Dividend** 

Purchasing fund shares in a taxable account shortly before a distribution is sometimes known as buying a dividend. In taxable accounts, you must pay income taxes on the distribution whether you reinvest the distribution or take it in cash. In addition, you will have to pay taxes on the distribution whether the value of your investment decreased, increased or remained the same after you bought the fund shares.

The risk in buying a dividend is that a fund's portfolio may build up taxable income and gains throughout the period covered by a distribution, as income is earned and securities are sold at a profit. The fund distributes the income and gains to you, after subtracting any losses, even if you did not own the shares when the income was earned or the gains occurred.

If you buy a dividend, you incur the full tax liability of the distribution period, but you may not enjoy the full benefit of the income earned or the gains realized in the fund's portfolio.

------

**Multiple Class Information**

The funds offer multiple classes of shares. The classes have different fees, expenses and/or minimum investment requirements. Different fees and expenses will affect performance.

Except as described below, all classes of shares of each fund have identical voting, dividend, liquidation and other rights, preferences, terms and conditions. The only differences among the classes are (a) each class may be subject to different expenses specific to that class; (b) each class has a different identifying designation or name; (c) each class has exclusive voting rights with respect to matters solely affecting such class; (d) each class may have different exchange privileges; and (e) the I Class may provide for conversion from that class into shares of the Investor Class of the same fund.

**Service, Distribution and Administrative Fees** 

Investment Company Act Rule 12b-1 permits mutual funds that adopt a written plan to pay certain expenses associated with the distribution of their shares out of fund assets. Each class, except the Investor Class, I Class and R6 Class, offered by this prospectus has a 12b-1 plan. The plans provide for the funds to pay annual fees of 0.25% for A Class and 0.50% for R Class to the distributor, for distribution and individual shareholder services, including past distribution services. The distributor pays all or a portion of such fees to the financial intermediaries that make the classes available. Because these fees may be used to pay for services that are not related to prospective sales of the funds, each class will continue to make payments under its plan even if it is closed to new investors. Because these fees are paid out of the funds' assets on an ongoing basis, over time these fees will increase the cost of your investment and may cost you more than paying other types of sales charges. For additional information about the plans and their terms, see *Multiple Class Structure* in the statement of additional information.

Certain financial intermediaries perform recordkeeping and administrative services for their clients that would otherwise be performed by American Century Investments' transfer agent. In some circumstances, the advisor will pay such service providers a fee for performing those services. Also, the advisor and the funds' distributor may make payments to intermediaries for various additional services, other expenses and/or the intermediaries' distribution of the fund out of their profits or other available sources. Such payments may be made for one or more of the following: (1) distribution, which may include expenses incurred by intermediaries for their sales activities with respect to the funds, such as preparing, printing and distributing sales literature and advertising materials and compensating registered representatives or other employees of such financial intermediaries for their sales activities, as well as the opportunity for the fund to be made available by such intermediaries; (2) shareholder services, such as providing individual and custom investment advisory services to clients of the financial intermediaries; and (3) marketing and promotional services, including business planning assistance, educating personnel about the funds, and sponsorship of sales meetings, which may include covering costs of providing speakers, meals and other entertainment. The distributor may pay partnership and/or sponsorship fees to support seminars, conferences, and other programs designed to educate intermediaries about the funds and may cover the expenses associated with attendance at such meetings, including travel costs. The distributor also may pay fees related to obtaining data regarding intermediary or financial advisor activities to assist American Century Investments with sales reporting, business intelligence, and training and education opportunities. These payments may create a conflict of interest by influencing the intermediary to recommend the funds over another investment. Ask your salesperson or visit your financial intermediary's website for more information. The amount of any payments described by this paragraph is determined by the advisor or the distributor, and all such amounts are paid out of their available assets, and not paid by you or the funds. As a result, the total expense ratio of the funds will not be affected by any such payments.

American Century Investments does not pay any fees to financial intermediaries on R6 Class shares.

The information in this Appendix is part of, and incorporated into, the fund's prospectus.

**Financial Intermediary Sales Charge Reduction and Waiver Information**

The availability of certain sales charge waivers and discounts will depend on whether you purchase your shares directly from the fund or through a financial intermediary. Intermediaries may have different policies and procedures regarding the availability of front-end sales load waivers or contingent deferred (back-end) sales load (CDSC) waivers, which are set forth below. In all instances, it is the investor's responsibility to notify the fund or the applicable financial intermediary at the time of purchase of any relationship or other facts qualifying the investor for sales charge waivers or discounts. **For waivers and discounts not available through a particular intermediary, shareholders will have to purchase fund shares directly from the fund or through another intermediary to receive these waivers or discounts.**

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• Breakpoints as described in this prospectus.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• Rights of accumulations which entitles shareholders to breakpoint discounts will be automatically calculated based on the aggregated holding of American Century Investments assets held by accounts within the purchaser's household at Baird. Eligible American Century Investments assets not held at Baird may be included in the rights of accumulations calculation only if the shareholder notifies his or her financial advisor about such assets.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• Letters of Intent (LOI) allow for breakpoint discounts based on anticipated purchases of American Century Investments funds through Baird, over a 13-month period of time.

**Policies Regarding Transactions Through Edward D. Jones & Co., L.P. ("Edward Jones")**

The following information has been provided by Edward Jones:

Effective on or after September 3, 2024, the following information supersedes prior information with respect to transactions and positions held in fund shares through an Edward Jones system. Clients of Edward Jones (also referred to as "shareholders") purchasing fund shares on the Edward Jones commission and fee-based platforms are eligible only for the following sales charge discounts (also referred to as "breakpoints") and waivers, which can differ from discounts and waivers described elsewhere in the mutual fund prospectus or statement of additional information ("SAI") or through another broker-dealer. In all instances, it is the shareholder's responsibility to inform Edward Jones at the time of purchase of any relationship, holdings of American Century, or other facts qualifying the purchaser for discounts or waivers. Edward Jones can ask for documentation of such circumstance. Shareholders should contact Edward Jones if they have questions regarding their eligibility for these discounts and waivers.

**Breakpoints**

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• Breakpoint pricing, otherwise known as volume pricing, at dollar thresholds as described in the prospectus.

------

**Rights of Accumulation ("ROA")**

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• The applicable sales charge on a purchase of Class A shares is determined by taking into account all share classes (except certain money market funds and any assets held in group retirement plans) of American Century held by the shareholder or in an account grouped by Edward Jones with other accounts for the purpose of providing certain pricing considerations ("pricing groups"). If grouping assets as a shareholder, this includes all share classes held on the Edward Jones platform and/or held on another platform. The inclusion of eligible fund family assets in the ROA calculation is dependent on the shareholder notifying Edward Jones of such assets at the time of calculation. Money market funds are included only if such shares were sold with a sales charge at the time of purchase or acquired in exchange for shares purchased with a sales charge.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• The employer maintaining a SEP IRA plan and/or SIMPLE IRA plan may elect to establish or change ROA for the IRA accounts associated with the plan to a plan-level grouping as opposed to including all share classes at a shareholder or pricing group level.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• ROA is determined by calculating the higher of cost minus redemptions or market value (current shares x NAV).

**Letter of Intent ("LOI")**

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• Through a LOI, shareholders can receive the sales charge and breakpoint discounts for purchases shareholders intend to make over a 13-month period from the date Edward Jones receives the LOI. The LOI is determined by calculating the higher of cost or market value of qualifying holdings at LOI initiation in combination with the value that the shareholder intends to buy over a 13-month period to calculate the front-end sales charge and any breakpoint discounts. Each purchase the shareholder makes during that 13-month period will receive the sales charge and breakpoint discount that applies to the total amount. The inclusion of eligible fund family assets in the LOI calculation is dependent on the shareholder notifying Edward Jones of such assets at the time of calculation. Purchases made before the LOI is received by Edward Jones are not adjusted under the LOI and will not reduce the sales charge previously paid. Sales charges will be adjusted if LOI is not met.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• If the employer maintaining a SEP IRA plan and/or SIMPLE IRA plan has elected to establish or change ROA for the IRA accounts associated with the plan to a plan-level grouping, LOIs will also be at the plan-level and may only be established by the employer.

**Sales Charge Waivers**

Sales charges are waived for the following shareholders and in the following situations:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• Associates of Edward Jones and its affiliates and other accounts in the same pricing group (as determined by Edward Jones under its policies and procedures) as the associate. This waiver will continue for the remainder of the associate's life if the associate retires from Edward Jones in good-standing and remains in good standing pursuant to Edward Jones' policies and procedures.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• Shares purchased in an Edward Jones fee-based program.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• Shares purchased through reinvestment of capital gains distributions and dividend reinvestment.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• Shares purchased from the proceeds of redeemed shares of the same fund family so long as the following conditions are met: the proceeds are from the sale of shares within 60 days of the purchase, the sale and purchase are made from a share class that charges a front load and one of the following ("Right of Reinstatement"):

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• The redemption and repurchase occur in the same account.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• The redemption proceeds are used to process an: IRA contribution, excess contributions, conversion, recharacterizing of contributions, or distribution, and the repurchase is done in an account within the same Edward Jones grouping for ROA.

The Right of Reinstatement excludes systematic or automatic transactions including, but not limited to, purchases made through payroll deductions, liquidations to cover account fees, and reinvestments from non-mutual fund products.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• Shares exchanged into Class A shares from another share class so long as the exchange is into the same fund and was initiated at the discretion of Edward Jones. Edward Jones is responsible for any remaining CDSC due to the fund company, if applicable. Any future purchases are subject to the applicable sales charge as disclosed in the prospectus.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• Exchanges from Class C shares to Class A shares of the same fund, generally, in the 84th month following the anniversary of the purchase date or earlier at the discretion of Edward Jones.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• Purchases of Class 529-A shares through a rollover from either another education savings plan or a security used for qualified distributions.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• Purchases of Class 529-A shares made for recontribution of refunded amounts.

------

**Contingent Deferred Sales Charge ("CDSC") Waivers**

If the shareholder purchases shares that are subject to a CDSC and those shares are redeemed before the CDSC is expired, the shareholder is responsible to pay the CDSC except in the following conditions:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• The death or disability of the shareholder.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• Systematic withdrawals with up to 10% per year of the account value.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• Return of excess contributions from an Individual Retirement Account (IRA).

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• Shares redeemed as part of a required minimum distribution for IRA and retirement accounts if the redemption is taken in or after the year the shareholder reaches qualified age based on applicable IRS regulations.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• Shares redeemed to pay Edward Jones fees or costs in such cases where the transaction is initiated by Edward Jones.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• Shares exchanged in an Edward Jones fee-based program.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• Shares acquired through NAV reinstatement.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• Shares redeemed at the discretion of Edward Jones for Minimum Balances, as described below.

**PFS Investments Inc. ("PFSI") Policies Regarding Transactions Through PFSI**

The following information supersedes all prior information with respect to transactions and positions held in fund shares purchased through PFSI and held on the mutual fund platform of its affiliate, Primerica Shareholder Services ("PSS"). Clients of PFSI (also referred to as "shareholders") purchasing fund shares on the PSS platform are eligible only for the following share classes, sales charge discounts (also referred to as "breakpoints") and waivers, which can differ from share classes, discounts and waivers described elsewhere in this prospectus or the related statement of additional information ("SAI") or through another broker-dealer.

**Share Classes** 

Class A shares: in non-retirement accounts, individual retirement accounts (IRA), SEP IRAs, SIMPLE IRAs, Keogh Plans, and all other account types unless expressly provided for below. Class C shares: only in accounts with existing Class C share holdings.

**Breakpoints** 

Breakpoint pricing at dollar thresholds as described in the prospectus of the fund you are purchasing.

**Rights of Accumulation ("ROA")** 

The applicable sales charge on a purchase of Class A shares is determined by taking into account all share classes (except any assets held in group retirement plans) of American Century Funds held by the shareholder on the PSS Platform.

It is the shareholder's responsibility to inform PFSI of all eligible fund family assets at the time of calculation. Shares of money market funds are included only if such shares were acquired in exchange for shares of another American Century Fund purchased with a sales charge. No shares of American Century Funds held by the shareholder away from the PSS platform will be granted ROA with shares of any American Century Fund purchased on the PSS platform.

Any SEP IRA plan, any SIMPLE IRA plan or any Payroll Deduction plan ("PDP") on the PSS platform will be defaulted to plan-level grouping for purposes of ROA, which allows each participating employee ROA with all other eligible shares held in plan accounts on the PSS platform. At any time, a participating employee may elect to exercise a one-time option to change grouping for purposes of ROA to shareholder- level grouping, which allows the plan account of the electing employee ROA with her other eligible holdings on the PSS platform, but not with all other eligible participant holdings in the plan. Eligible shares held in plan accounts electing shareholder-level grouping will not be available for purposes of ROA to plan accounts electing plan-level grouping.

ROA is determined by calculating the higher of cost minus redemptions or current market value (current shares x NAV).

**Letter of Intent ("LOI")** 

By executing a LOI, shareholders can receive the sales charge and breakpoint discounts for purchases shareholders intend to make over a 13-month period through PFSI, from the date PSS receives the LOI. The purchase price of the LOI is determined by calculating the higher of cost or market value of qualifying holdings at LOI initiation in combination with the dollar amount the shareholder intends to invest over a 13-month period to arrive at total investment for purposes of determining any breakpoint discount and the applicable front-end sales charge. Each purchase the shareholder makes during that 13-month period will receive the sales charge and breakpoint discount that applies to the projected total investment.

Only holdings of American Century Funds on the PSS platform are eligible for inclusion in the LOI calculation and the shareholder must notify PFSI of all eligible assets at the time of calculation. It is the shareholder's responsibility to inform PFSI at the time of a purchase of all holdings of American Century Funds on the PSS platform, or other facts qualifying the purchaser for this discount.

Purchases made before the LOI is received by PSS are not adjusted under the LOI, and the LOI will not reduce any sales charge previously paid. Sales charges will be automatically adjusted if the total purchases required by the LOI are not met.

If an employer maintaining a SEP IRA plan, SIMPLE IRA plan or non-IRA PDP on the PSS platform has elected to establish or change ROA for the accounts associated with the plan to a plan-level grouping, LOIs will also be at the plan-level and may only be established by the employer. LOIs are not available to PDP IRA plans on the PSS platform with plan-level grouping for purposes of ROA, but are available to any participating employee that elects shareholder-level grouping for purposes of ROA.

Shares exchanged into Class A shares from another share class so long as the exchange is into the same fund and was initiated at the discretion of PFSI. PFSI is responsible for any remaining CDSC due to the fund company, if applicable. Any future purchases are subject to the applicable sales charge as disclosed in the prospectus.

**Policies Regarding Fund Purchases Through PFSI That Are Not Held on the PSS Platform** 

Class R shares are available through PFSI only in 401(k) plans covering a business owner with no employees, commonly referred to as a one-participant 401(k) plan or solo 401(k).

**Fund Investment Guidelines**

The funds' advisor, American Century Investment Management, Inc., intends to operate the funds as "funds of funds," meaning that substantially all of the funds' assets will be invested in other American Century Investments mutual funds (the underlying funds), as described in the funds' prospectuses. More details about each of the underlying funds are available in its prospectus and statement of additional information, which are available on our website. This section explains the extent to which the underlying funds' advisor can use various investment vehicles and strategies in managing the underlying funds' assets. Descriptions of the investment techniques and risks associated with each appear in the section, *Investment Strategies and Risks,* which begins on page 8. In the case of the funds' principal investment strategies, these descriptions elaborate upon the discussion contained in the prospectus.

Each fund is diversified as defined in the Investment Company Act of 1940 (the Investment Company Act). Diversified means that, with respect to 75% of its total assets, each fund will not invest more than 5% of its total assets in the securities of a single issuer or own more than 10% of the outstanding voting securities of a single issuer (other than U.S. government securities and securities of other investment companies). Additionally, the underlying funds are generally diversified and so indirectly provide broad exposure to a large number of securities.

To meet federal tax requirements for qualification as a regulated investment company, each fund must limit its investments so that at the close of each quarter of its taxable year

(1)no more than 25% of its total assets are invested in the securities of a single issuer (other than the U.S. government or a regulated investment company), and

(2)with respect to at least 50% of its total assets, no more than 5% of its total assets are invested in the securities of a single issuer (other than the U.S. government or a regulated investment company) and it does not own more than 10% of the outstanding voting securities of a single issuer.

In general, within the restrictions outlined here and in the funds' prospectuses, the portfolio managers have broad powers to decide how to invest fund assets.

Investments are varied according to what is judged advantageous under changing economic conditions. It is the advisor's policy to retain maximum flexibility in management without restrictive provisions as to the proportion of one or another class of securities that may be held, subject to the investment restrictions described in the funds' prospectuses and below. Unless otherwise noted, all investment restrictions described below and in each fund's prospectus are measured at the time of the transaction in the security. If market action affecting fund securities (including, but not limited to, appreciation, depreciation or a credit rating event) causes a fund to exceed an investment restriction, the advisor is not required to take immediate action. Under normal market conditions, however, the advisor's policies and procedures indicate that the advisor will not make any purchases that will make the fund further outside the investment restriction.

As described in the funds' prospectuses, each fund's assets are allocated among underlying funds that represent major asset classes, including equity securities (stock funds), fixed-income securities (bond funds) and short-term investments (short-term funds). Through the underlying funds, each fund's assets are further diversified among various investment categories and disciplines within the major asset classes.

The equity portion of a fund's portfolio may be indirectly invested in any type of domestic or foreign equity or equity-equivalent security, primarily common stocks, that meets certain fundamental and technical standards of selection. Equity equivalents include securities that permit the fund to receive an equity interest in an issuer, the opportunity to acquire an equity interest in an issuer, or the opportunity to receive a return on its investment that permits the fund to benefit from the growth over time in the equity of an issuer. Examples of equity securities and equity equivalents include preferred stock and convertible securities. Equity equivalents also may include securities whose value or return is derived from the value or return of a different security. Derivative instruments are discussed in greater detail on page 10 under the heading *Derivative Instruments.* 

The underlying funds' portfolio managers use several investment disciplines in managing the equity portion of each fund's portfolio, including growth, value and quantitative management disciplines. The growth discipline generally seeks long-term capital appreciation by investing in companies whose earnings and revenue trends meet the advisor's investment criteria. This includes companies whose earnings and revenues are not only growing, but growing at an accelerating pace. It also includes companies whose growth rates, although still negative, are less negative than prior periods. The value investment discipline seeks capital growth by investing in equity securities of companies that the managers believe to be temporarily undervalued.

The advisor believes both value investing and growth investing provide the potential for appreciation over time. Value investing tends to provide less volatile results. This lower volatility means that the price of value stocks tends not to fall as significantly as the price of growth stocks in down markets. However, value stocks do not usually appreciate as significantly as growth stocks do in up markets. In keeping with the diversification theme of these funds, and as a result of management's belief that these styles are complementary, both disciplines will be represented to some degree in each portfolio at all times.

As noted, the value investment discipline tends to be less volatile than the growth investment discipline. As a result, the more conservative funds (including portfolios with earlier target years) will generally have a higher proportion of their equity investments in

------

value stocks than the more aggressive funds (including funds with more distant target years). Likewise, the more aggressive funds will generally have a greater proportion of growth stocks than the more conservative funds.

In addition, the equity portion of each fund's portfolio will be further diversified among underlying funds that invest in small, medium and large companies. This approach provides investors with an additional level of diversification and enables investors to achieve a broader exposure to the various capitalization ranges without having to invest directly in multiple funds.

Quantitative management disciplines also may be represented in a portion of each fund's portfolio. These disciplines combine elements of both growth and value investing and are intended to reduce overall volatility relative to the market. American Century Investments' quantitative management disciplines utilize a multi-step process that draws heavily on computer technology. In the first step, the portfolio managers rank stocks from most attractive to least attractive using a computer model that combines measures of a stock's value, as well as measures of its growth potential, among others. To measure value, the managers may use ratios of stock price-to-book value and stock price-to-cash flow, among others. To measure growth, the managers may use the rate of growth of a company's earnings and changes in its earnings estimates, as well as other factors.

In the second step, the managers use a technique called portfolio optimization. In portfolio optimization, the managers build a portfolio of stocks from the ranking described above that they believe will provide the optimal balance between risk and expected return. The goal is to create a fund that provides better returns than its benchmark without taking on significant additional risk.

Finally, the managers review the output of the quantitative model, considering factors such as risk management, transaction costs, and liquidity management.

A portion of each fund's portfolio also may be invested in underlying funds that use short selling as a principal investment strategy. A short position arises when a fund sells a security it does not own but has borrowed in anticipation that the market price of the security will decline. The proceeds from the security sold short are used to buy additional securities (a long position). A fund's use of short selling creates leverage in an attempt to increase returns.

The fixed-income portion of a fund's portfolio indirectly may include U.S. Treasury securities, securities issued or guaranteed by the U.S. government or a foreign government, or an agency or instrumentality of the U.S. or a foreign government, and nonconvertible debt obligations issued by U.S. or foreign corporations. Some of the underlying funds also may invest in mortgage-related and other asset-backed securities, which are described in greater detail on page 19 under the heading *Mortgage-Related and Other Asset-Backed Securities*. As with the equity portion of a fund's portfolio, the fixed-income portion of a fund's portfolio will be diversified among the various fixed-income investment categories described above.

The value of fixed-income securities fluctuates based on changes in interest rates and in the credit quality of the issuers. Debt securities that comprise part of a fund's fixed-income portfolio may include investment-grade and high-yield securities. Investment-grade means that at the time of purchase, such obligations are rated within the four highest categories by a nationally recognized statistical rating organization for example, at least Baa by Moody's Investors Service, Inc. (Moody's) or BBB by Standard & Poor's Corporation (S&P), or, if not rated, are of equivalent investment quality as determined by the managers. According to Moody's, bonds rated Baa are medium-grade and possess some speculative characteristics. A BBB rating by S&P indicates S&P's belief that a security exhibits a satisfactory degree of safety and capacity for repayment but is more vulnerable to adverse economic conditions and changing circumstances.

High-yield securities, sometimes referred to as junk bonds, are higher risk, nonconvertible debt obligations that are rated below investment-grade securities, or are unrated, but with similar credit quality. Each One Choice Target Date Portfolio and One Choice Blend+ Portfolio may invest a minority portion of its assets in the High Income Fund or other underlying funds that invest primarily in below investment-grade (high-yield) securities. One Choice Portfolio: Very Conservative, One Choice Portfolio: Conservative and One Choice Portfolio: Moderate may invest up to 5% of their assets, and One Choice Portfolio: Aggressive and One Choice Portfolio: Very Aggressive may invest up to 10% of their assets in the High Income Fund or other similar underlying funds.

There are no credit or maturity restrictions on the fixed-income securities in which the high-yield portion of a fund's portfolio may be indirectly invested. Debt securities rated below investment grade are considered by many to be predominantly speculative. Changes in economic conditions or other circumstances are more likely to lead to a weakened capacity to make principal and interest payments on such securities than is the case with higher-quality debt securities. Regardless of rating levels, all debt securities considered for purchase by an underlying fund are analyzed by the managers to determine, to the extent reasonably possible, that the planned investment is consistent with the investment objective of the fund.

Short-term investments include underlying funds that invest in fixed-income or debt instruments and have a shorter-term weighted average duration, typically three years or less. Duration is an indication of the relative sensitivity of a security's market value to changes in interest rates.

The funds also may invest in underlying funds that invest primarily in foreign securities.

The funds are primarily "strategic" rather than "tactical" allocation funds, which means the managers generally do not try to time the market to identify when a major reallocation should be made. Instead, the managers use a longer-term approach in pursuing the funds' investment objectives and thus select a blend of underlying funds in the various asset classes. However, in order to better balance risks

------

in changing market environments, the portfolio managers may make modest deviations from the neutral mix in light of prevailing market conditions.

Other than One Choice In Retirement Portfolio, each One Choice Target Date Portfolio's neutral mix is adjusted according to a predetermined glide path until the fund reaches its target date. By the time a fund reaches its target date, its neutral mix will become fixed and will match that of One Choice In Retirement Portfolio. The One Choice Blend+ Portfolios' neutral mixes will be similarly adjusted according to a predetermined glide path (decreasing exposure to stocks and increasing exposure to bonds and short-term investments) until five years after the target date. The managers also will review each fund's allocations quarterly to determine whether rebalancing is appropriate. For the One Choice Target Risk Portfolios, the managers regularly review each fund's investments and allocations and may make changes in the underlying fund holdings within each asset class or to a fund's asset mix (generally within the operating ranges stated in the prospectus) to emphasize investments that they believe will provide the most favorable outlook for achieving the fund's objective. Recommended reallocations may be implemented promptly or may be implemented gradually. In order to minimize the impact of reallocations on a fund's performance, the managers will generally attempt to reallocate assets gradually.

The funds attempt to diversify across asset classes and investment categories to a greater extent than funds that invest primarily in equity securities or primarily in fixed-income securities. However, the funds are managed to a specific target year or a general risk profile and may not provide an appropriately balanced investment plan for all investors.

**Fund Investments and Risks**

**Investment Strategies and Risks** 

The underlying funds' portfolio managers also may use the investment vehicles and techniques described in this section in managing the underlying funds' assets. This section also details the risks associated with each, because each investment vehicle and technique contributes to the One Choice Target Date Portfolios', One Choice Blend+ Portfolios, and the One Choice Target Risk Portfolios' overall risk profiles. In the *Investment Strategies and Risks* section, references to funds mean the underlying funds, unless otherwise noted.

**Bank Loans** 

Some of the funds may invest in bank loans, which include senior secured and unsecured floating rate loans of corporations, partnerships, or other entities. Typically, these loans hold a senior position in the borrower's capital structure, may be secured by the borrower's assets and have interest rates that reset frequently. These loans are usually rated non-investment grade by the rating agencies. An economic downturn generally leads to higher non-payment and default rates by borrowers, and a bank loan can lose a substantial part of its value due to these and other adverse conditions and events. However, as compared to junk bonds, senior floating rate loans are typically senior in the capital structure and are often secured by collateral of the borrower. A fund's investments in bank loans are subject to credit risk, and there is no assurance that the liquidation of collateral would satisfy the claims of the borrower's obligations in the event of non-payment of scheduled interest or principal, or that the collateral could be readily liquidated. The interest rates on many bank loans reset frequently, and therefore investors are subject to the risk that the return will be less than anticipated when the investment was first made. Most bank loans, like most investment grade bonds, are not traded on any national securities exchange. Bank loans generally have less liquidity than investment grade bonds and there may be less publicly available information about them.

A fund eligible to invest in bank loans may purchase bank loans from the primary market, from other lenders (sometimes referred to as loan assignments) or it may also acquire a participation interest in another lender's portion of the bank loan. Large bank loans to corporations or governments may be shared or syndicated among several lenders, usually commercial or investment banks. A fund may participate in such syndicates, or can buy part of a loan, becoming a direct lender. Participation interests involve special types of risk, including liquidity risk and the risks of being a lender. Risks of being a lender include credit risk (the borrower's ability to meet required principal and interest payments under the terms of the loan), industry risk (the borrower's industry's exposure to rapid change or regulation), financial risk (the effectiveness of the borrower's financial policies and use of leverage), liquidity risk (the adequacy of the borrower's back-up sources of cash), and collateral risk (the sufficiency of the collateral's value to repay the loan in the event of non-payment or default by the borrower). If a fund purchases a participation interest, it may only be able to enforce its rights through the lender, and may assume the credit risk of the lender in addition to the credit risk of the borrower.

In addition, transactions in bank loans may take more than seven days to settle. As a result, the proceeds from the sale of bank loans may not be readily available to make additional investments or to meet the fund's redemption obligations. To mitigate these risks, the fund monitors its short-term liquidity needs in light of the longer settlement period of bank loans. Some bank loan interests may not be considered securities or registered under the Securities Act of 1933 and therefore not afforded the protections of the federal securities laws.

------

**Convertible Securities**

A convertible security is a bond, debenture, note, preferred stock or other security that may be converted into or exchanged for a prescribed amount of common stock of the same or a different issuer within a particular time period at a specified price or formula. A convertible security entitles the holder to receive the interest paid or accrued on debt or the dividend paid on preferred stock until the convertible security matures or is redeemed, converted or exchanged. Before conversion or exchange, such securities ordinarily provide a stream of income with generally higher yields than common stocks of the same or similar issuers, but lower than the yield on non-convertible debt. Of course, there can be no assurance of current income because issuers of convertible securities may default on their obligations. In addition, there can be no assurance of capital appreciation because the value of the underlying common stock will fluctuate. Because of the conversion feature, the managers consider some convertible securities to be equity equivalents.

The price of a convertible security will normally fluctuate in some proportion to changes in the price of the underlying asset. A convertible security is subject to risks relating to the activities of the issuer and/or general market and economic conditions. The stream of income typically paid on a convertible security may tend to cushion the security against declines in the price of the underlying asset. However, the stream of income causes fluctuations based upon changes in interest rates and the credit quality of the issuer. In general, the value of a convertible security is a function of (1) its yield in comparison with yields of other securities of comparable maturity and quality that do not have a conversion privilege, and (2) its worth, at market value, if converted or exchanged into the underlying common stock. The price of a convertible security often reflects such variations in the price of the underlying common stock in a way that a non-convertible security does not. At any given time, investment value generally depends upon such factors as the general level of interest rates, the yield of similar nonconvertible securities, the financial strength of the issuer and the seniority of the security in the issuer's capital structure.

A convertible security may be subject to redemption at the option of the issuer at a predetermined price. If a convertible security held by a fund is called for redemption, the fund would be required to permit the issuer to redeem the security and convert it to underlying common stock or to cash, or would sell the convertible security to a third party, which may have an adverse effect on the fund. A convertible security may feature a put option that permits the holder of the convertible security to sell that security back to the issuer at a predetermined price. A fund generally invests in convertible securities for their favorable price characteristics and total return potential and normally would not exercise an option to convert unless the security is called or conversion is forced.

Contingent convertible securities (sometimes referred to as CoCos or Additional Tier 1 instruments) generally either convert into equity or have their principal written down upon the occurrence of certain trigger events, which may be linked to the issuer's stock price, regulatory capital thresholds, regulatory actions relating to the issuer's continued viability, or other pre-specified events. Under certain circumstances, CoCos may be subject to an automatic write-down of the principal amount or value of the securities, sometimes to zero, thereby cancelling the securities. If such an event occurs, a fund may not have any rights to repayment of the principal amount of the securities that has not become due. Additionally, a fund may not be able to collect interest payments or dividends on such securities. In the event of liquidation or dissolution of the issuer, CoCos generally rank junior to the claims of holders of the issuer's other debt obligations. CoCos also may provide for the mandatory conversion of the security into common stock of the issuer under certain circumstances. Because the common stock of an issuer may not pay a dividend, a fund may experience reduced yields (or no yield) as a result of the conversion. Conversion of the security from debt to equity would deepen the subordination of the investor and thereby worsen the fund's standing in bankruptcy.

**Counterparty Risk**

A fund will be exposed to the credit risk of the counterparties with which, or the brokers, dealers and exchanges through which, it deals, whether it engaged in exchange traded or off-exchange transactions.

A fund is subject to the risk that issuers of the instruments in which it invests and trades may default on their obligations under those instruments, and that certain events may occur that have an immediate and significant adverse effect on the value of those instruments. There can be no assurance that an issuer of an instrument in which a fund invests will not default, or that an event that has an immediate and significant adverse effect on the value of an instrument will not occur, and that a fund will not sustain a loss on a transaction as a result.

Transactions entered into by a fund may be executed on various U.S. and non-U.S. exchanges, and may be cleared and settled through various clearinghouses, custodians, depositories and prime brokers throughout the world. Although a fund attempts to execute, clear and settle the transactions through entities the advisor believes to be sound, there can be no assurance that a failure by any such entity will not lead to a loss to a fund.

**Cyber Security Risk** 

As the funds increasingly rely on technology and information systems to operate, they become susceptible to operational risks linked to security breaches in those information systems. Both calculated attacks and unintentional events can cause failures in the funds' information systems. Cyber attacks can include acquiring unauthorized access to information systems, usually through hacking or the use of malicious software, for purposes of stealing assets or confidential information, corrupting data, or disrupting fund operations. Cyber attacks can also occur without direct access to information systems, for example by making network services unavailable to

------

intended users. Cyber security failures by, or breaches of the information systems of, the advisor, distributors, broker-dealers, other service providers (including, but not limited to, index providers, fund accountants, custodians, transfer agents and administrators), or the issuers of securities the fund invests in may also cause disruptions and impact the funds' business operations. Breaches in information security may result in financial losses, interference with the funds' ability to calculate NAV, impediments to trading, inability of fund shareholders to transact business, violations of applicable privacy and other laws, regulatory fines, penalties, reputational damage, reimbursement or other compensation costs, or additional compliance costs. Additionally, the funds may incur substantial costs to prevent future cyber incidents. The funds have business continuity plans in the event of, and risk management systems to help prevent, such cyber attacks, but these plans and systems have limitations including the possibility that certain risks have not been identified. Moreover, the funds do not control the cyber security plans and systems of our service providers and other third party business partners. The funds and their shareholders could be negatively impacted as a result.

**Derivative Instruments**

To the extent permitted by their investment objectives and policies, the funds may invest in derivative instruments. Generally, a derivative instrument is a financial arrangement the value of which is based on, or derived from, a traditional security, asset, or market index. A fund may not invest in a derivative instrument if its credit, interest rate, liquidity, counterparty or other associated risks are outside acceptable limits set forth in its prospectus. The advisor has a derivatives risk management program that includes policies and procedures reasonably designed to manage each fund's respective derivatives risk. The derivatives risk management program complies with Rule 18f-4 of the Investment Company Act. Unless a fund qualifies as a limited derivatives user, the fund will be required to participate in the derivatives risk management program, which includes compliance with value-at-risk based leverage limits, oversight by a derivatives risk manager, and additional reporting and disclosure regarding its derivatives positions. A fund designated as a limited derivatives user has policies and procedures to manage its aggregate derivatives risk. The advisor will periodically report on the derivatives risk management program to the Board of Directors/Trustees.

Examples of common derivative instruments include futures contracts, warrants, structured notes, credit default swaps, options contracts, swap transactions and forward currency contracts.

The risks associated with investments in derivatives differ from, and may be greater than, the risks associated with investing directly in traditional investments.

**Leverage Risk** – Relatively small market movements may cause large changes in an investment's value. Leverage is associated with certain types of derivatives or trading strategies. Certain transactions in derivatives (such as futures transactions or sales of put options) involve substantial leverage and may expose a fund to potential losses that exceed the amount of initial investment.

**Hedging Risk** – When used to hedge against a position in a fund, losses on a derivative instrument are typically offset by gains on the hedged position, and vice versa. Thus, though hedging can minimize or cancel out losses, it can also have the same effect on gains. Occasionally, there may be imperfect matching between the derivative and the underlying security, such a match may prevent the fund from achieving the intended hedge or expose it to a risk of loss. There is no guarantee that a fund's hedging strategy will be effective. Portfolio managers may decide not to hedge against any given risk either because they deem such risk improbable or they do not foresee the occurrence of the risk. Additionally, certain risks may be impossible to hedge against.

**Correlation Risk** – The value of the underlying security, interest rate, market index or other financial asset may not move in the direction the portfolio managers anticipate. Additionally, the value of the derivative may not move or react to changes in the underlying security, interest rate, market index or other financial asset as anticipated.

**Illiquidity Risk** – There may be no liquid secondary market, which may make it difficult or impossible to close out a position when desired. For exchange-traded derivatives contracts, daily limits on price fluctuations and speculative position limits set by the exchanges on which a fund transacts in derivative instruments may prevent profitable liquidation of positions, subjecting a fund to the potential of greater losses.

**Settlement Risk** – A fund may have an obligation to deliver securities or currency pursuant to a derivatives transaction that such fund does not own at the inception of the derivatives trade.

**Counterparty Risk** – A counterparty may fail to perform its obligations. Because bi-lateral derivative transactions are traded between counterparties based on contractual relationships, a fund is subject to the risk that a counterparty will not perform its obligations under the related contracts. Although each fund intends to enter into transactions only with counterparties which the advisor believes to be creditworthy, there can be no assurance that a counterparty will not default and that the funds will not sustain a loss on a transaction as a result. In situations where a fund is required to post margin or other collateral with a counterparty, the counterparty may fail to segregate the collateral or may commingle the collateral with the counterparty's own assets. As a result, in the event of the counterparty's bankruptcy or insolvency, a fund's collateral may be subject to the conflicting claims of the counterparty's creditors, and a fund may be exposed to the risk of a court treating a fund as a general unsecured creditor of the counterparty, rather than as the owner of the collateral.

**Volatility Risk** – A fund could face higher volatility because some derivative instruments create leverage.

------

***Foreign Currency Exchange Transactions***

A fund may conduct foreign currency transactions on a spot basis (i.e., for prompt delivery and settlement) or forward basis (i.e., by entering into forward currency exchange contracts, currency options and futures transactions for hedging or any other lawful purpose). Although foreign exchange dealers generally do not charge a fee for such transactions, they do realize a profit based on the difference between the prices at which they are buying and selling various currencies.

Forward contracts are customized transactions that require a specific amount of a currency to be delivered at a specific exchange rate on a specific date or range of dates in the future. Forward contracts are generally traded in an interbank market directly between currency traders (usually larger commercial banks) and their customers. The parties to a forward contract may agree to offset or terminate the contract before its maturity, or may hold the contract to maturity and complete the contemplated currency exchange.

The following summarizes the principal currency management strategies involving forward contracts. A fund may also use swap agreements, indexed securities, and options and futures contracts relating to foreign currencies for the same purposes.

(1)*Settlement Hedges or Transaction Hedges* – When the portfolio managers wish to lock in the U.S. dollar price of or proceeds from a foreign currency denominated security when a fund is purchasing or selling the security, a fund may enter into a forward contract to do so. This type of currency transaction, often called a "settlement hedge" or "transaction hedge," protects the fund against an adverse change in foreign currency values between the date a security is purchased or sold and the date on which payment is made or received (i.e., settled). Forward contracts to purchase or sell a foreign currency may also be used by a fund in anticipation of future purchases or sales of securities denominated in foreign currency, even if the specific investments have not yet been selected by the portfolio managers. This strategy is often referred to as "anticipatory hedging."

(2)*Position Hedges* – When the portfolio managers believe that the currency of a particular foreign country may suffer substantial decline against the U.S. dollar, a fund may enter into a forward contract to sell foreign currency for a fixed U.S. dollar amount approximating the value of some or all of its portfolio securities either denominated in, or whose value is tied to, such foreign currency. This use of a forward contract is sometimes referred to as a "position hedge." For example, if a fund owned securities denominated in Euro, it could enter into a forward contract to sell Euro in return for U.S. dollars to hedge against possible declines in the Euro's value. This hedge would tend to offset both positive and negative currency fluctuations, but would not tend to offset changes in security values caused by other factors.

A fund could also hedge the position by entering into a forward contract to sell another currency expected to perform similarly to the currency in which the fund's existing investments are denominated. This type of hedge, often called a "proxy hedge," could offer advantages in terms of cost, yield or efficiency, but may not hedge currency exposure as effectively as a simple position hedge against U.S. dollars. This type of hedge may result in losses if the currency used to hedge does not perform similarly to the currency in which the hedged securities are denominated.

The precise matching of forward contracts in the amounts and values of securities involved generally would not be possible because the future values of such foreign currencies will change as a consequence of market movements in the values of those securities between the date the forward contract is entered into and the date it matures. Predicting short-term currency market movements is extremely difficult, and the successful execution of a short-term hedging strategy is highly uncertain. Normally, consideration of the prospect for currency parities will be incorporated into the long-term investment decisions made with respect to overall diversification strategies. However, the managers believe that it is important to have flexibility to enter into such forward contracts when they determine that a fund's best interests may be served.

At the maturity of the forward contract, the fund may either sell the portfolio security and make delivery of the foreign currency, or it may retain the security and terminate the obligation to deliver the foreign currency by purchasing an "offsetting" forward contract with the same currency trader obligating the fund to purchase, on the same maturity date, the same amount of the foreign currency.

It is impossible to forecast with absolute precision the market value of portfolio securities at the expiration of the forward contract. Accordingly, it may be necessary for a fund to purchase additional foreign currency on the spot market (and bear the expense of such purchase) if the market value of the security is less than the amount of foreign currency the fund is obligated to deliver and if a decision is made to sell the security and make delivery of the foreign currency the fund is obligated to deliver.

(3)*Shifting Currency Exposure* – A fund may also enter into forward contracts to shift its investment exposure from one currency into another for hedging purposes or to enhance returns. This may include shifting exposure from U.S. dollars to foreign currency, or from one foreign currency to another foreign currency and may result in the fund being obligated to deliver an amount in excess of the value of its securities or other assets denominated in that currency (a "net short" position). This strategy tends to limit exposure to the currency sold, and increase exposure to the currency that is purchased, much as if a fund had sold a security denominated in one currency and purchased an equivalent security denominated in another currency. For example, if the portfolio managers believed that the U.S. dollar may suffer a substantial decline against the Euro, they could enter into a forward contract to purchase Euros for a fixed amount of U.S. dollars. This transaction would protect against losses resulting from a decline in the value of the U.S. dollar, but would cause the fund to assume the risk of fluctuations in the value of the Euro.

Successful use of currency management strategies will depend on the fund management team's skill in analyzing currency values. Currency management strategies may substantially subject a fund's investment exposure to changes in currency rates and could result in losses to a fund if currencies do not perform as the portfolio managers anticipate. For example, if a currency's value rose at a time when the portfolio manager hedged a fund by selling the currency in exchange for U.S. dollars, a fund would not participate in the currency's appreciation. Similarly, if the portfolio managers increase a fund's exposure to a currency and that currency's value declines, a fund will sustain a loss. There is no assurance that the portfolio managers' use of foreign currency management strategies will be advantageous to a fund or that they will hedge at appropriate times.

The fund will generally cover outstanding forward contracts by maintaining liquid portfolio securities denominated in, or whose value is tied to, the currency underlying the forward contract or the currency being hedged.

Certain funds may also invest in nondeliverable forward (NDF) currency transactions. An NDF is a transaction that represents an agreement between the fund and a counterparty to buy or sell a specified amount of a particular currency at an agreed upon foreign exchange rate on a future date. Unlike other currency transactions, there is no physical delivery of the currency on the settlement of an NDF transaction. Rather, the fund and the counterparty agree to net the settlement by making a payment in U.S. dollars or another fully convertible currency that represents any difference between the foreign exchange rate agreed upon at the inception of the NDF agreement and the actual exchange rate on the agreed upon future date. The fund may use an NDF contract to gain exposure to foreign currencies which are not internationally traded or if the markets for such currencies are heavily regulated or highly taxed. When currency exchange rates do not move as anticipated, a fund could sustain losses on the NDF transaction. This risk is heightened when the transactions involve currencies of emerging market countries. Additionally, certain NDF transactions which involve currencies of less developed countries or with respect to certain other currencies, may be relatively illiquid.

***Futures and Options***

Futures and options are commonly used for traditional hedging purposes to attempt to protect a fund from exposure to changing interest rates, securities prices or currency exchange rates. They also are used for cash management purposes as a low-cost method of gaining exposure to a particular securities market without investing directly in those securities.

**Futures**

A fund may enter into futures contracts, options or options on futures contracts. Futures contracts provide for the sale by one party and purchase by another party of a specific security at a specified future time and price. Generally, futures transactions will be used to

• protect against a decline in market value of the fund's securities (taking a short futures position),

• protect against the risk of an increase in market value for securities in which the fund generally invests at a time when the fund is not fully invested (taking a long futures position), or

• provide a temporary substitute for the purchase of an individual security that may not be purchased in an orderly fashion.

Some futures and options strategies, such as selling futures, buying puts and writing calls, hedge a fund's investments against price fluctuations. Other strategies, such as buying futures, writing puts and buying calls, tend to increase market exposure. Although other techniques may be used to control a fund's exposure to market fluctuations, the use of futures contracts may be a more effective means of hedging this exposure. While a fund pays brokerage commissions in connection with opening and closing out futures positions, these costs are lower than the transaction costs incurred in the purchase and sale of the underlying securities.

The sale of a future by a fund means the fund becomes obligated to deliver the security (or securities, in the case of an index future) at a specified price on a specified date. The purchase of a future means the fund becomes obligated to buy the security (or securities) at a specified price on a specified date. The portfolio managers may engage in futures and options transactions based on securities indices that are consistent with the funds' investment objectives, such as the S&P 500 Index. The managers also may engage in futures and options transactions based on specific securities. Futures contracts are traded on national futures exchanges. Futures exchanges and trading are regulated under the Commodity Exchange Act by the Commodity Futures Trading Commission (CFTC), a U.S. government agency.

Index futures contracts differ from traditional futures contracts in that when delivery takes place, no stocks or bonds change hands. Instead, these contracts settle in cash at the spot market value of the index. Although other types of futures contracts by their terms call for actual delivery or acceptance of the underlying securities, in most cases the contracts are closed out before the settlement date. A futures position may be closed by taking an opposite position in an identical contract (i.e., buying a contract that has previously been sold or selling a contract that has previously been bought).

Unlike when the fund purchases or sells a security, no price is paid or received by the fund upon the purchase or sale of the future. Initially, the fund will be required to deposit an amount of cash or securities equal to a varying specified percentage of the contract amount. This amount is known as initial margin. The margin deposit is intended to ensure completion of the contract (delivery or acceptance of the underlying security) if it is not terminated prior to the specified delivery date. A margin deposit does not constitute a margin transaction for purposes of the fund's investment restrictions. Minimum initial margin requirements are established by the futures exchanges and may be revised. In addition, brokers may establish margin deposit requirements that are higher than the exchange minimums. Cash held in the margin accounts generally is not income-producing. However, coupon bearing securities, such

------

as Treasury bills and bonds, held in margin accounts generally will earn income. Subsequent payments to and from the broker, called variation margin, will be made on a daily basis as the price of the underlying securities or index fluctuates, making the future more or less valuable, a process known as marking the contract to market. Changes in variation margin are recorded by the fund as unrealized gains or losses. At any time prior to expiration of the future, the fund may elect to close the position by taking an opposite position. A final determination of variation margin is then made; additional cash is required to be paid by or released to the fund and the fund realizes a loss or gain.

**Options**

By buying a put option, a fund obtains the right (but not the obligation) to sell the instrument underlying the option at a fixed strike price and in return a fund pays the current market price for the option (known as the option premium). A fund may terminate its position in a put option it has purchased by allowing it to expire, by exercising the option or by entering into an offsetting transaction, if a liquid market exists. If the option is allowed to expire, a fund will lose the entire premium it paid. If a fund exercises a put option on a security, it will sell the instrument underlying the option at the strike price. The buyer of a typical put option can expect to realize a gain if the value of the underlying instrument falls substantially. However, if the price of the instrument underlying the option does not fall enough to offset the cost of purchasing the option, a put buyer can expect to suffer a loss limited to the amount of the premium paid, plus related transaction costs.

The features of call options are essentially the same as those of put options, except that the buyer of a call option obtains the right to purchase, rather than sell, the instrument underlying the option at the option's strike price. The buyer of a typical call option can expect to realize a gain if the value of the underlying instrument increases substantially and can expect to suffer a loss if security prices do not rise sufficiently to offset the cost of the option.

When a fund writes a put option, it takes the opposite side of the transaction from the option's buyer. In return for the receipt of the premium, a fund assumes the obligation to pay the strike price for the instrument underlying the option if the other party to the option chooses to exercise it. A fund may seek to terminate its position in a put option it writes before exercise by purchasing an offsetting option in the market at its current price. Otherwise, a fund must continue to be prepared to pay the strike price while the option is outstanding, regardless of price changes, and must continue to post margin as discussed below. If the price of the underlying instrument rises, a put writer would generally realize as profit the premium it received. If the price of the underlying instrument remains the same over time, it is likely that the writer will also profit, because it should be able to close out the option at a lower price. If the price of the underlying instrument falls, the put writer would expect to suffer a loss.

A fund writing a call option is obligated to sell or deliver the option's underlying instrument in return for the strike price upon exercise of the option. Writing calls generally is a profitable strategy if the price of the underlying instrument remains the same or falls. A call writer offsets part of the effect of a price decline by receipt of the option premium, but gives up some ability to participate in security price increases. The writer of an exchange traded put or call option on a security, an index of securities or a futures contract is required to deposit cash or securities or a letter of credit as margin and to make mark to market payments of variation margin as the position becomes unprofitable.

**Options on Futures**

By purchasing an option on a futures contract, a fund obtains the right, but not the obligation, to sell the futures contract (a put option) or to buy the contract (a call option) at a fixed strike price. A fund can terminate its position in a put option by allowing it to expire or by exercising the option. If the option is exercised, the fund completes the sale of the underlying security at the strike price. Purchasing an option on a futures contract does not require a fund to make margin payments unless the option is exercised.

Some of the funds may write (or sell) call options that obligate them to sell (or deliver) the option's underlying instrument upon exercise of the option. While the receipt of option premiums would mitigate the effects of price declines, the funds would give up some ability to participate in a price increase on the underlying security. If a fund were to engage in options transactions, it would own the futures contract at the time a call was written and would keep the contract open until the obligation to deliver it pursuant to the call expired.

**Risks Related to Futures and Options Transactions**

Futures and options prices can be volatile, and trading in these markets involves certain risks. If the portfolio managers apply a hedge at an inappropriate time or judge interest rate or equity market trends incorrectly, futures and options strategies may lower a fund's return.

A fund could suffer losses if it is unable to close out its position because of an illiquid secondary market. Futures contracts may be closed out only on an exchange that provides a secondary market for these contracts, and there is no assurance that a liquid secondary market will exist for any particular futures contract at any particular time. Consequently, it may not be possible to close a futures position when the portfolio managers consider it appropriate or desirable to do so. In the event of adverse price movements, a fund would be required to continue making daily cash payments to maintain its required margin. If the fund had insufficient cash, it might have to sell portfolio securities to meet daily margin requirements at a time when the portfolio managers would not otherwise elect to do so. In addition, a fund may be required to deliver or take delivery of instruments underlying futures contracts it holds. The portfolio

------

managers will seek to minimize these risks by limiting the futures contracts entered into on behalf of the funds to those traded on national futures exchanges and for which there appears to be a liquid secondary market.

A fund could suffer losses if the prices of its futures and options positions were poorly correlated with its other investments or if securities underlying futures contracts purchased by a fund had different maturities than those of the portfolio securities being hedged. Such imperfect correlation may give rise to circumstances in which a fund loses money on a futures contract at the same time that it experiences a decline in the value of its hedged portfolio securities. A fund also could lose margin payments it has deposited with a margin broker if, for example, the broker became bankrupt.

Most futures exchanges limit the amount of fluctuation permitted in futures contract prices during a single trading day. The daily limit establishes the maximum amount that the price of a futures contract may vary either up or down from the previous day's settlement price at the end of the trading session. Once the daily limit has been reached in a particular type of contract, no trades may be made on that day at a price beyond the limit. However, the daily limit governs only price movement during a particular trading day and, therefore, does not limit potential losses. In addition, the daily limit may prevent liquidation of unfavorable positions. Futures contract prices have occasionally moved to the daily limit for several consecutive trading days with little or no trading, thereby preventing prompt liquidation of futures positions and subjecting some futures traders to substantial losses.

If a fund's futures commission merchant (FCM) becomes bankrupt or insolvent, or otherwise defaults on its obligations to the fund, the fund may not receive all amounts owed to it in respect of its trading, despite the clearinghouse fully discharging all of its obligations. The Commodity Exchange Act requires an FCM to segregate all funds received from its customers with respect to regulated futures transactions from such FCM's proprietary funds. If an FCM were not to do so to the full extent required by law, the assets of an account might not be fully protected in the event of the bankruptcy of an FCM. Furthermore, in the event of an FCM's bankruptcy, a fund would be limited to recovering only a pro rata share of all available funds segregated on behalf of an FCM's combined customer accounts, even though certain property specifically traceable to the fund (for example, U.S. Treasury bills deposited by the fund) was held by an FCM. FCM bankruptcies have occurred in which customers were unable to recover from the FCM's estate the full amount of their funds on deposit with such FCM and owing to them. Such situations could arise due to various factors, or a combination of factors, including inadequate FCM capitalization, inadequate controls on customer trading and inadequate customer capital. In addition, in the event of the bankruptcy or insolvency of a clearinghouse, the fund might experience a loss of funds deposited through its FCM as margin with the clearinghouse, a loss of unrealized profits on its open positions, and the loss of funds owed to it as realized profits on closed positions. Such a bankruptcy or insolvency might also cause a substantial delay before the fund could obtain the return of funds owed to it by an FCM who was a member of such clearinghouse.

When purchasing an option on a futures contract, the fund assumes the risk of the premium paid for the option plus related transaction costs. The purchase of an option on a futures contract also entails the risk that changes in the value of the underlying futures contract will not be fully reflected in the value of the option purchased.

**Restrictions on the Use of Futures Contracts and Options**

Some funds may enter into futures contracts, options, options on futures contracts, or swap agreements as permitted under the Commodity Futures Trading Commission (CFTC) rules. The advisor to each fund has claimed exclusion from the definition of the term "commodity pool operator" under the Commodity Exchange Act and, therefore, are not subject to registration or regulation as a commodity pool operator under that Act with respect to its provision of services to each fund.

Certain rules adopted by the CFTC may impose additional limits on the ability of a fund to invest in futures contracts, options on futures, swaps, and certain other commodity interests if its investment advisor does not register with the CFTC as a "commodity pool operator" with respect to such fund. It is expected that the funds will be able to execute their investment strategies within the limits adopted by the CFTC's rules. As a result, the advisor does not intend to register with the CFTC as a commodity pool operator on behalf of any of the funds. In the event that one of the funds engages in transactions that necessitate future registration with the CFTC, the advisor will register as a commodity pool operator and comply with applicable regulations with respect to that fund.

***Swap Agreements*** 

A fund may invest in swap agreements, consistent with its investment objective and strategies. A fund may enter into a swap agreement in order to, for example, attempt to obtain or preserve a particular return or spread at a lower cost than obtaining a return or spread through purchases and/or sales of instruments in other markets; protect against currency fluctuations; attempt to manage duration to protect against any increase in the price of securities the fund anticipates purchasing at a later date; or gain exposure to certain markets in the most economical way possible.

Swap agreements are two-party contracts entered into primarily by institutional investors for periods ranging from a few weeks to more than one year. In a standard "swap" transaction, two parties agree to exchange the returns (or differentials in rates of return) earned or realized on particular predetermined investments or instruments, which may be adjusted for an interest factor. The gross returns to be exchanged or "swapped" between the parties are generally calculated with respect to a "notional amount," i.e., the return on or increase in value of a particular dollar amount invested at a particular interest rate, in a particular foreign currency, or in a "basket" of securities representing a particular index. Forms of swap agreements include, for example, interest rate swaps, under which fixed- or floating-rate interest payments on a specific principal amount are exchanged and total return swaps, under which one

------

party agrees to pay the other the total return of a defined underlying asset (usually an index, including inflation indexes, stock, bond or defined portfolio of loans and mortgages) in exchange for fee payments, often a variable stream of cashflows based on a reference rate. The funds may enter into credit default swap agreements to hedge an existing position by purchasing or selling credit protection. Credit default swaps enable an investor to buy/sell protection against a credit event of a specific issuer. The seller of credit protection against a security or basket of securities receives an up-front or periodic payment to compensate against potential default event(s). The fund may enhance returns by selling protection or attempt to mitigate credit risk by buying protection. Market supply and demand factors may cause distortions between the cash securities market and the credit default swap market.

Whether a fund's use of swap agreements will be successful depends on the advisor's ability to predict correctly whether certain types of investments are likely to produce greater returns than other investments. Interest rate swaps could result in losses if interest rate changes are not correctly anticipated by the fund. Total return swaps could result in losses if the reference index, security, or investments do not perform as anticipated by the fund. Credit default swaps could result in losses if the fund does not correctly evaluate the creditworthiness of the issuer on which the credit default swap is based. Because they are two-party contracts and because they may have terms of greater than seven days, swap agreements may be considered to be illiquid. Moreover, a fund bears the risk of loss of the amount expected to be received under a swap agreement in the event of the default or bankruptcy of a swap agreement counterparty. The funds will enter into swap agreements only with counterparties that meet certain standards of creditworthiness or that are cleared through a Derivatives Clearing Organization ("DCO"). Certain restrictions imposed on the funds by the Internal Revenue Code may limit the funds' ability to use swap agreements.

The Dodd-Frank Wall Street Reform and Consumer Protection Act (the "Dodd-Frank Act") and related regulatory developments require the clearing and exchange-trading of certain standardized derivative instruments that the CFTC and SEC have defined as "swaps." The CFTC has implemented mandatory exchange-trading and clearing requirements under the Dodd-Frank Act and the CFTC continues to approve contracts for central clearing. Although exchange trading is designed to decrease counterparty risk, it does not do so entirely because the fund will still be subject to the credit risk of the central clearinghouse. Cleared swaps are subject to margin requirements imposed by both the central clearinghouse and the clearing member FCM. Uncleared swaps are now subject to posting and collecting collateral on a daily basis to secure mark-to-market obligations (variation margin). Swaps data reporting may subject a fund to administrative costs, and the safeguards established to protect trader anonymity may not function as expected. Exchange trading, central clearing, margin requirements, and data reporting regulations may increase a fund's cost of hedging risk and, as a result, may affect shareholder returns.

**Equity Equivalents**

In addition to investing in common stocks, the funds may invest in other equity securities and equity equivalents, including securities that permit a fund to receive an equity interest in an issuer, the opportunity to acquire an equity interest in an issuer, or the opportunity to receive a return on its investment that permits the fund to benefit from the growth over time in the equity of an issuer. Examples of equity securities and equity equivalents include preferred stock, convertible preferred stock and convertible securities.

Equity equivalents also may include securities whose value or return is derived from the value or return of a different security.

**Foreign Securities**

The funds may invest in the securities (including debt securities) of foreign issuers, including foreign governments, when these securities meet their standards of selection. Securities of foreign issuers may trade in the U.S. or foreign securities markets.

The funds may make such investments either directly in foreign securities or indirectly by purchasing depositary receipts or depositary shares of similar instruments (depositary receipts) for foreign securities. Depositary receipts are securities that are listed on exchanges or quoted in the domestic over-the-counter markets in one country, but represent shares of issuers domiciled in another country. Direct investments in foreign securities may be made either on foreign securities exchanges or in the over-the-counter markets.

Subject to their investment objective and policies, the funds may invest in common stocks, convertible securities, preferred stocks, bonds, notes and other debt securities of foreign issuers and debt securities of foreign governments and their agencies. The credit quality standards applicable to domestic debt securities purchased by each fund are also applicable to its foreign securities investments.

Investments in foreign securities may present certain risks, including:

**Currency Risk** – The value of the foreign investments held by the funds may be significantly affected by changes in currency exchange rates. The dollar value of a foreign security generally decreases when the value of the dollar rises against the foreign currency in which the security is denominated and tends to increase when the value of the dollar falls against such currency. In addition, the value of fund assets may be affected by losses and other expenses incurred in converting between various currencies in order to purchase and sell foreign securities, and by currency restrictions, exchange control regulation, currency devaluations and political developments.

**Social, Political and Economic Risk** – The economies of many of the countries in which the funds invest are not as developed as the economy of the United States and may be subject to significantly different forces. Political or social instability, expropriation, nationalization, confiscatory taxation and limitations on the removal of funds or other assets also could adversely affect the value of

------

investments. Further, the funds may find it difficult or be unable to enforce ownership rights, pursue legal remedies or obtain judgments in foreign courts.

**Regulatory Risk** – Foreign companies generally are not subject to the regulatory controls imposed on U.S. issuers and, in general, there is less publicly available information about foreign securities than is available about domestic securities. Many foreign companies are not subject to uniform accounting, auditing and financial reporting standards, practices and requirements comparable to those applicable to domestic companies and there may be less stringent investor protection and disclosure standards in some foreign markets. Certain jurisdictions do not currently provide the Public Company Accounting Oversight Board ("PCAOB") with sufficient access to inspect audit work papers and practices, or otherwise do not cooperate with U.S. regulators, potentially exposing investors in U.S. capital markets to significant risks. Income from foreign securities owned by the funds may be reduced by a withholding tax at the source, which would reduce dividend income payable to shareholders.

**Market and Trading Risk** – Brokerage commission rates in foreign countries, which generally are fixed rather than subject to negotiation as in the United States, are likely to be higher. The securities markets in many of the countries in which the funds may invest have substantially less trading volume than the principal U.S. markets. As a result, the securities of some companies in these countries may be less liquid, more volatile and harder to value than comparable U.S. securities. Furthermore, one securities broker may represent all or a significant part of the trading volume in a particular country, resulting in higher trading costs and decreased liquidity due to a lack of alternative trading partners. There generally is less government regulation and supervision of foreign stock exchanges, brokers and issuers, which may make it difficult to enforce contractual obligations.

**Clearance and Settlement Risk** – Foreign securities markets also have different clearance and settlement procedures, and in certain markets there have been times when settlements have been unable to keep pace with the volume of securities transactions, making it difficult to conduct such transactions. Delays in clearance and settlement could result in temporary periods when assets of the funds are uninvested and no return is earned. The inability of the funds to make intended security purchases due to clearance and settlement problems could cause the funds to miss attractive investment opportunities. Inability to dispose of portfolio securities due to clearance and settlement problems could result either in losses to the funds due to subsequent declines in the value of the portfolio security or, if the fund has entered into a contract to sell the security, liability to the purchaser.

**Ownership Risk** – Evidence of securities ownership may be uncertain in many foreign countries. In many of these countries, the most notable of which is the Russian Federation, the ultimate evidence of securities ownership is the share register held by the issuing company or its registrar. While some companies may issue share certificates or provide extracts of the company's share register, these are not negotiable instruments and are not effective evidence of securities ownership. In an ownership dispute, the company's share register is controlling. As a result, there is a risk that a fund's trade details could be incorrectly or fraudulently entered on the issuer's share register at the time of the transaction, or that a fund's ownership position could thereafter be altered or deleted entirely, resulting in a loss to the fund. While the funds intend to invest directly in Russian companies that utilize an independent registrar, there can be no assurance that such investments will not result in a loss to the funds.

**Sanctions** – The U.S. may impose economic sanctions against companies in various sectors of certain countries. This could limit a fund's investment opportunities in such countries, impairing the fund's ability to invest in accordance with its investment strategy and/or to meet its investment objective. For example, a fund may be prohibited from investing in securities issued by companies subject to such sanctions. In addition, the sanctions may require a fund to freeze its existing investments in sanctioned companies, prohibiting the fund from selling or otherwise transacting in these investments. Current sanctions or the threat of potential sanctions may also impair the value or liquidity of affected securities and negatively impact a fund.

In early 2022, the United States and countries throughout the world imposed economic sanctions on Russia in response to its military invasion of Ukraine. The sanctions are broad and include restrictions on the Russian government as well as Russian companies, individuals, and banking entities. The sanctions and other measures, such as boycotts or changes in consumer preferences, will likely cause declines in the value and liquidity of Russian securities, downgrades in the credit ratings of Russian securities, devaluation of Russia's currency, and increased market volatility and disruption in Russia and throughout the world. Sanctions and similar measures, such as banning Russia from financial transaction systems that facilitate international transfers of funds, could limit or prevent the funds from selling and buying impacted securities both in Russia and in other markets. Such measures will likely cause significant delay in the settlement of impacted securities transactions or prevent settlement all together. The lack of available market prices for such securities may cause the funds to use fair value procedures to value certain securities. The consequences of the war and sanctions may negatively impact other regional and global economic markets. Additionally, Russia may take counter measures or engage in retaliatory actions—including cyberattacks and espionage—which could further disrupt global markets and supply chains. Companies in other countries that do business with Russia and the global commodities market for oil and natural gas, especially, will likely feel the impact of the sanctions. The sanctions, together with the potential for a wider armed or cyber conflict, could increase financial market volatility globally and negatively impact the funds' performance beyond any direct exposure to Russian issuers or securities.

------

**United Kingdom Investment Risk** - Commonly known as "Brexit," the United Kingdom's exit from the EU occurred in January of 2021. The UK and the EU continue to work to establish regulatory frameworks for cooperation on financial services. Continuing uncertainty in the UK, EU, and other financial markets may result in volatility, fluctuations in asset values and exchange rates, decreased liquidity and unwillingness or inability of financial and other counterparties to enter into transactions.

**Risk of Investing in China** - Investing in Chinese securities is riskier than investing in U.S. securities. Although the Chinese government is currently implementing reforms to promote foreign investment and reduce government economic control, there is no guarantee that the reforms will be ongoing or effective. Investing in China involves risk of loss due to nationalization, expropriation, and confiscation of assets and property. Losses may also occur due to new or expanded restrictions on foreign investments or repatriation of capital. Participants in the Chinese market are subject to less regulation and oversight than participants in the U.S. market. This may lead to trading volatility, difficulty in the settlement and recording of transactions, and uncertainty in interpreting and applying laws and regulations. Reduction in spending on Chinese products and services, institution of tariffs or other trade barriers, or a downturn in the economies of any of China's key trading partners may adversely affect the securities of Chinese issuers. Regional conflict could also have an adverse effect on the Chinese economy.

The SEC and the PCAOB continue to have concerns about their ability to inspect international auditing standards of U.S. companies operating in China and PCAOB-registered auditing firms in China. Because the SEC and PCAOB have limited access to information about these auditing firms and are restricted from inspecting the audit work and practices of registered accountants in China, there is the risk that material information about Chinese issuers may be unavailable. As a result, there is substantially greater risk that disclosures will be incomplete or misleading and, in the event of investor harm, substantially less access to recourse, in comparison to U.S. domestic companies.

The U.S. government may occasionally place restrictions on investments in Chinese companies. For example, in November 2020, an Executive Order was issued that prohibits U.S. persons from purchasing or investing in certain publicly-traded securities of companies identified as "Communist Chinese military companies" or in instruments that are designed to provide investment exposure to those companies. The companies identified may change from time to time. A fund may incur losses if more investors attempt to sell such securities or if the fund is unable to participate in an otherwise attractive investment. Securities that are or become prohibited may become less liquid and their market prices may decline. In addition, the market for securities of other Chinese-based issuers may also be negatively impacted, resulting in reduced liquidity and price declines.

Due to Chinese governmental restrictions on foreign ownership of companies in certain industries, Chinese operating companies often rely on variable interest entity (VIE) structures to raise capital from non-Chinese investors. In a VIE structure, a China-based operating company establishes an entity—typically offshore—that enters into service and other contracts with the Chinese company designed to provide economic exposure to the company. The offshore entity then issues shares that are sold to non-Chinese investors. A U.S.-listed company and its China-based VIE might appear to be the same company—because they are presented in a consolidated manner—but they are not. The U.S.-listed company's control over the China-based company is predicated on contracts with the China-based company, not equity ownership. The Chinese government has never explicitly approved these structures and thus could determine at any time, and without notice, that the VIE's underlying contractual arrangements violate Chinese law. If either the China-based company (or its officers, directors, or Chinese equity owners) breach those contracts with the U.S.-listed shell company, or Chinese law changes in a way that affects the enforceability of these arrangements, or those contracts are otherwise not enforceable under Chinese law, U.S. investors may suffer losses with limited recourse available. Additionally, investments in the U.S.-listed company may be affected by conflicts of interest and duties between the legal owners of the China-based VIE and the stockholders of the U.S.-listed company. Finally, if Chinese companies listed on U.S. exchanges, including ADRs and companies that rely on VIE structures, do not meet U.S. accounting standards and auditor oversight requirements they may be delisted, which would likely decrease the liquidity and value of these securities.

**Inflation-Indexed Securities** 

The funds may purchase inflation-indexed securities issued by the U.S. Treasury, U.S. government agencies and instrumentalities other than the U.S. Treasury, and entities other than the U.S. Treasury or U.S. government agencies and instrumentalities.

Inflation-indexed securities are designed to offer a return linked to inflation, thereby protecting future purchasing power of the money invested in them. However, inflation-indexed securities provide this protected return only if held to maturity. In addition, inflation-indexed securities may not trade at par value. Real interest rates (the market rate of interest less the anticipated rate of inflation) change over time as a result of many factors, such as what investors are demanding as a true value for money. When real rates do change, inflation-indexed securities prices will be more sensitive to these changes than conventional bonds, because these securities were sold originally based upon a real interest rate that is no longer prevailing. Should market expectations for real interest rates rise, the price of inflation-indexed securities and the share price of a fund holding these securities will fall. Investors in the funds should be prepared to accept not only this share price volatility but also the possible adverse tax consequences it may cause.

An investment in securities featuring inflation-adjusted principal and/or interest involves factors not associated with more traditional fixed-principal securities. Such factors include the possibility that the inflation index may be subject to significant changes, that changes in the index may or may not correlate to changes in interest rates generally or changes in other indices, or that the resulting

------

interest may be greater or less than that payable on other securities of similar maturities. In the event of sustained deflation, it is possible that the amount of semiannual interest payments, the inflation-adjusted principal of the security or the value of the stripped components will decrease. If any of these possibilities are realized, a fund's net asset value could be negatively affected.

**Initial Public Offerings**

The funds may invest in initial public offerings (IPOs) of common stock or other equity securities issued by a company. The purchase of securities in an IPO may involve higher transaction costs than those associated with the purchase of securities already traded on exchanges or other established markets. In addition to the risks associated with equity securities generally, IPO securities may be subject to additional risk due to factors such as the absence of a prior public market, unseasoned trading and speculation, a potentially small number of securities available for trading, limited information about the issuer and other factors. These factors may cause IPO shares to be volatile in price. While a fund may hold IPO securities for a period of time, it may sell them in the aftermarket soon after the purchase, which could increase portfolio turnover and lead to increased expenses such as commissions and transaction costs. Investments in IPOs could have a magnified impact (either positive or negative) on performance if a fund's assets are relatively small. The impact of IPOs on a fund's performance may tend to diminish as assets grow.

**Inverse Floaters**

An inverse floater is a type of derivative instrument that bears an interest rate that moves inversely to market interest rates. As market interest rates rise, the interest rate on inverse floaters goes down, and vice versa. Generally, this is accomplished by expressing the interest rate on the inverse floater as an above-market fixed rate of interest, reduced by an amount determined by reference to a market-based or bond-specific floating interest rate (as well as by any fees associated with administering the inverse floater program).

Inverse floaters may be issued in conjunction with an equal amount of Dutch Auction floating-rate bonds (floaters), or a market-based index may be used to set the interest rate on these securities. A Dutch Auction is an auction system in which the price of the security is gradually lowered until it meets a responsive bid and is sold. Floaters and inverse floaters may be brought to market (1) by a broker-dealer who purchases fixed-rate bonds and places them in a trust; or (2) by an issuer seeking to reduce interest expenses by using a floater/inverse floater structure in lieu of fixed-rate bonds.

In the case of a broker-dealer structured offering (where underlying fixed-rate bonds have been placed in a trust), distributions from the underlying bonds are allocated to floater and inverse floater holders in the following manner:

(i)Floater holders receive interest based on rates set at a six-month interval or at a Dutch Auction, which is typically held every 28 to 35 days. Current and prospective floater holders bid the minimum interest rate that they are willing to accept on the floaters, and the interest rate is set just high enough to ensure that all of the floaters are sold.

(ii)Inverse floater holders receive all of the interest that remains, if any, on the underlying bonds after floater interest and auction fees are paid. The interest rates on inverse floaters may be significantly reduced, even to zero, if interest rates rise.

Procedures for determining the interest payment on floaters and inverse floaters brought to market directly by the issuer are comparable, although the interest paid on the inverse floaters is based on a presumed coupon rate that would have been required to bring fixed-rate bonds to market at the time the floaters and inverse floaters were issued.

Where inverse floaters are issued in conjunction with floaters, inverse floater holders may be given the right to acquire the underlying security (or to create a fixed-rate bond) by calling an equal amount of corresponding floaters. The underlying security may then be held or sold. However, typically, there are time constraints and other limitations associated with any right to combine interests and claim the underlying security.

Floater holders subject to a Dutch Auction procedure generally do not have the right to put back their interests to the issuer or to a third party. If a Dutch Auction fails, the floater holder may be required to hold its position until the underlying bond matures, during which time interest on the floater is capped at a predetermined rate.

The secondary market for floaters and inverse floaters may be limited. The market value of inverse floaters tends to be significantly more volatile than the market value of fixed-rate bonds.

**Investing in Emerging Market Countries** 

The funds may invest in securities of issuers in emerging market (developing) countries. The funds generally consider a security to be an emerging markets security if its issuer is located outside the following developed countries list, which is subject to change: Australia, Austria, Belgium, Bermuda, Canada, Denmark, Finland, France, Germany, Hong Kong, Ireland, Israel, Italy, Japan, Luxembourg, The Netherlands, New Zealand, Norway, Portugal, Singapore, Spain, Sweden, Switzerland, the United Kingdom and the United States. Certain funds may consider additional countries to be emerging markets, as described in those funds' prospectuses or statements of additional information. In determining where a company is located, the portfolio managers will consider various factors, including where the company is headquartered, where the company's principal operations are located, where a majority of the company's revenues are derived, where the principal trading market is located and the country in which the company was legally organized. The weight given to each of these factors will vary depending on the circumstances in a given case.

------

Investing in securities of issuers in emerging market countries involves exposure to significantly higher risk than investing in countries with developed markets. Risks of investing in emerging markets countries may relate to lack of liquidity, market manipulation, limited reliable access to capital, and differing foreign investment structures. Emerging market countries may have economic structures that generally are less diverse and mature, and political systems that can be expected to be less stable than those of developed countries. Securities prices in emerging market countries can be significantly more volatile than in developed countries, reflecting the greater uncertainties of investing in lesser developed markets and economies. In particular, emerging market countries may have relatively unstable governments, and may present the risk of nationalization of businesses, expropriation, confiscatory taxation or in certain instances, reversion to closed-market, centrally planned economies. Such countries may also have less protection of property rights than developed countries.

The economies of emerging market countries may be based predominantly on only a few industries or may be dependent on revenues from particular commodities or on international aid or developmental assistance, may be highly vulnerable to changes in local or global trade conditions, and may suffer from extreme and volatile debt burdens or inflation rates. In addition, securities markets in emerging market countries may trade a relatively small number of securities and may be unable to respond effectively to increases in trading volume, potentially resulting in a lack of liquidity and in volatility in the price of securities traded on those markets. Also, securities markets in emerging market countries typically offer less regulatory protection for investors.

**Investment in Issuers with Limited Operating Histories** 

Some funds may invest a portion of their assets in the equity securities of issuers with limited operating histories. The managers consider an issuer to have a limited operating history if that issuer has a record of less than three years of continuous operation. The managers will consider periods of capital formation, incubation, consolidations, and research and development in determining whether a particular issuer has a record of three years of continuous operation.

Investments in securities of issuers with limited operating histories may involve greater risks than investments in securities of more mature issuers. By their nature, such issuers present limited operating histories and financial information upon which the managers may base their investment decision on behalf of the funds. In addition, financial and other information regarding such issuers, when available, may be incomplete or inaccurate.

For purposes of this limitation, "issuers" refers to operating companies that issue securities for the purposes of issuing debt or raising capital as a means of financing their ongoing operations. It does not, however, refer to registered investment companies, or other entities, corporate or otherwise, that are created for the express purpose of securitizing obligations or income streams. For example, a fund's investments in a trust created for the purpose of pooling mortgage obligations or other financial assets would not be subject to the limitation.

**LIBOR Transition Risk**

The London Interbank Offered Rate ("LIBOR") was a benchmark interest rate intended to be representative of the rate at which major international banks who are members of the British Bankers Association lend to one another over short-terms. Following manipulation allegations, financial institutions began phasing out the use of LIBOR, and publication of all LIBOR settings has now ceased. The transition to a replacement rate or rates may lead to increased volatility or illiquidity in markets for instruments that previously relied on LIBOR. The transition may also result in a change in the value of certain instruments the funds hold or a change in the cost of temporary borrowing for the funds. With the discontinuance of LIBOR, the LIBOR replacement rate may be lower than market expectations, which could have an adverse impact on the value of preferred and debt-securities with floating or fixed-to-floating rate coupons. The transition away from LIBOR could result in losses to the funds.

**Loan Participation Notes**

In terms of their functioning and investment risk, loan participation notes ("LPNs") are comparable to an investment in "normal" bonds. In return for the investor's commitment of capital, the issuer makes regular interest payments and, at maturity or in accordance with an agreed upon amortization schedule, the note is repaid at par.

However, in contrast to "normal" bonds, there are three parties involved in the issuance of an LPN. The legal issuer, typically a bankruptcy-remote, limited purpose entity, issues notes to investors and uses the proceeds received from investors to make loans to the borrower-with each loan generally having substantially identical payment terms to the related note issued by the issuer. The borrower is typically an operating company, and the issuer's obligations under a note are typically limited to the extent of any capital repayments and interest payments made by the borrower under the related loan. Accordingly, the investor generally assumes the credit risk of the underlying borrower. The loan participation note structure is generally used to provide the borrower more efficient financing in the capital markets than the borrower would be able to obtain if it issued notes directly.

In the event of a default by the borrower of an LPN, the fund may experience delays in receiving payments of interest and principal while the note issuer enforces and liquidates the underlying collateral, and there is no guarantee that the underlying collateral will cover the principal and interest owed to the fund under the LPN.

------

LPNs are generally subject to liquidity risk. Even though an LPN may be traded on an exchange there can be no assurance that a liquid market will develop for the LPNs, that holders of the LPNs will be able to sell their LPNs, or that such holders will be able to sell their LPNs for a price that reflects their value.

Depending on the creditworthiness of the underlying borrower, LPNs may be subject to the risk of investing in high-yield securities. Additionally, LPNs are generally utilized by foreign borrowers and therefore may be subject to the risk of investing in foreign securities and emerging market risk. Such foreign risk could include interest payments being subject to withholding tax.

**Loans of Portfolio Securities** 

In order to realize additional income, a fund may lend its portfolio securities. Such loans may not exceed one-third of the fund's total assets valued at market, however, this limitation does not apply to purchases of debt securities in accordance with the fund's investment objectives, policies and limitations, or to repurchase agreements with respect to portfolio securities.

Cash received from the borrower as collateral through loan transactions may be invested in other eligible securities. Investing this cash subjects that investment to market appreciation or depreciation. If a borrower defaults on a securities loan because of insolvency or other reasons, the lending fund could experience delays or costs in recovering the securities it loaned; if the value of the loaned securities increased over the value of the collateral, the fund could suffer a loss. To minimize the risk of default on securities loans, the advisor adheres to guidelines prescribed by the Board of Directors governing lending of securities. These guidelines strictly govern:

• the type and amount of collateral that must be received by the fund;

• the circumstances under which additions to that collateral must be made by borrowers;

• the return to be received by the fund on the loaned securities;

• the limitations on the percentage of fund assets on loan; and

• the credit standards applied in evaluating potential borrowers of portfolio securities.

In addition, the guidelines require that the fund have the option to terminate any loan of a portfolio security at any time and set requirements for recovery of securities from borrowers.

**Mortgage-Related and Other Asset-Backed Securities** 

The funds may purchase mortgage-related and other asset-backed securities. Mortgage pass-through securities are securities representing interests in "pools" of mortgages in which payments of both interest and principal on the securities are generally made monthly, in effect "passing through" monthly payments made by the individual borrowers on the residential mortgage loans that underlie the securities (net of fees paid to the issuer or guarantor of the securities).

Early repayment of principal on mortgage pass-through securities (arising from prepayments of principal due to sale of the underlying property, refinancing or foreclosure, net of fees and costs that may be incurred) may expose the funds to a lower rate of return upon reinvestment of principal. Also, if a security subject to prepayment were purchased at a premium, in the event of prepayment, the value of the premium would be lost. As with other fixed-income securities, when interest rates rise, the value of a mortgage-related security generally will decline; however, when interest rates decline, the value of mortgage-related securities with prepayment features may not increase as much as other fixed-income securities.

Payment of principal and interest on some mortgage pass-through securities (but not the market value of the securities themselves) may be guaranteed by the full faith and credit of the U.S. government, as in the case of securities guaranteed by the Government National Mortgage Association (GNMA), or guaranteed by agencies or instrumentalities of the U.S. government, as in the case of securities guaranteed by the Federal National Mortgage Association (Fannie Mae) or the Federal Home Loan Mortgage Corporation (Freddie Mac), which are supported only by the discretionary authority of the U.S. government to purchase the agency's obligations. Since September 2008, Fannie Mae and Freddie Mac have operated under a conservatorship administered by the Federal Housing Finance Agency (FHFA). In addition, the U.S. Treasury has entered into senior preferred stock purchase agreements (SPSPAs) to provide additional financing to Fannie Mae and Freddie Mac. Although the SPSPAs are intended to provide Fannie Mae and Freddie Mac with the necessary cash resources to meet their obligations, Fannie Mae and Freddie Mac continue to operate as going concerns while in conservatorship, and each remains liable for all of its obligations, including its guaranty obligations, associated with its mortgage-backed securities.

The future status and role of Fannie Mae or Freddie Mac could be impacted by, among other things, the actions taken and restrictions placed on Fannie Mae or Freddie Mac by the FHFA in its role as conservator, the restrictions placed on Fannie Mae's or Freddie Mac's operations and activities under the senior preferred stock purchase agreements, market responses to developments at Fannie Mae or Freddie Mac, and future legislative and regulatory action that alters the operations, ownership, structure and/or mission of Fannie Mae or Freddie Mac, each of which may, in turn, impact the value of, and cash flows on, any securities guaranteed by Fannie Mae and Freddie Mac.

------

The funds also may invest in collateralized mortgage obligations (CMOs). CMOs are mortgage-backed securities issued by government agencies; single-purpose, stand-alone financial subsidiaries; trusts established by financial institutions; or similar institutions. The funds may buy CMOs that:

• are collateralized by pools of mortgages in which payment of principal and interest of each mortgage is guaranteed by an agency or instrumentality of the U.S. government;

• are collateralized by pools of mortgages in which payment of principal and interest are guaranteed by the issuer, and the guarantee is collateralized by U.S. government securities; and

• are securities in which the proceeds of the issue are invested in mortgage securities and payments of principal and interest are supported by the credit of an agency or instrumentality of the U.S. government.

**To-Be-Announced Mortgage-Backed Securities**

To-be-announced (TBA) commitments are forward agreements for the purchase or sale of securities, which are described in greater detail under the heading *When-Issued and Forward Commitment Agreements.* A fund may gain exposure to mortgage-backed securities through TBA transactions. TBA mortgage-backed securities typically are debt securities structured by agencies such as Fannie Mae and Freddie Mac. In a typical TBA mortgage transaction, certain terms (such as price) are fixed, with delayed payment and delivery on an agreed upon future settlement date. The specific mortgage-backed securities to be delivered are not typically identified at the trade date but the delivered security must meet specified terms (such as issuer, interest rate, and underlying mortgage terms). Consequently, TBA mortgage-backed transactions involve increased interest rate risk because the underlying mortgages may be less favorable at delivery than anticipated. TBA mortgage contracts also involve a risk of loss if the value of the underlying security to be purchased declines prior to delivery date. The yield obtained for such securities may be higher or lower than yields available in the market on delivery date. The funds may also take short positions in TBA investments. To enter a short sale of a TBA security, a fund effectively agrees to sell a security it does not own at a future date and price. The funds generally anticipate closing short TBA positions before delivery of the respective security is required, however if the fund is unable to close a position, the fund would have to purchase the securities needed to settle the short sale. Such purchases could be at a different price than anticipated, and the fund would lose or gain money based on the acquisition price.

**Credit Risk Transfer Securities**

Credit risk transfer securities (CRTs) transfer the credit risk related to certain types of mortgage-backed securities to the owner of the credit risk transfer. Government entities, such as Fannie Mae or Freddie Mac, primarily issue CRTs. CRTs trade in an active over the counter market facilitated by well-known investment banks. Though an active OTC market for trading exists, CRTs may be less liquid than exchange traded securities. CRTs are unguaranteed and unsecured fixed or floating rate general obligations. Holders of CRTs receive compensation for providing credit protection to the issuer. The issuer of the CRT selects the pool of mortgage loans based on that entity's eligibility criteria, and the performance of the CRTs will be directly affected by the selection of such underlying mortgage loans. The risks associated with an investment in a CRT differ from the risks of investing in mortgage-backed securities issued by government entities or issued by private issuers because some or all of the mortgage default or credit risk associated with the underlying mortgage loans is transferred to investors. Accordingly, investors in CRTs could lose some or all of their investment if the underlying mortgage loans default.

**Obligations with Term Puts Attached** 

The funds may invest in fixed-rate bonds subject to third-party puts and participation interests in such bonds that are held by a bank in trust or otherwise, which have tender options or demand features attached. These tender options or demand features permit the funds to tender (or put) their bonds to an institution at periodic intervals and to receive the principal amount thereof. The managers expect the funds will pay more for securities with puts attached than for securities without these liquidity features.

Because it is difficult to evaluate the likelihood of exercise or the potential benefit of a put, puts normally will be determined to have a value of zero, regardless of whether any direct or indirect consideration is paid. Accordingly, puts as separate securities are not expected to affect the funds' weighted average maturities. When a fund has paid for a put, the cost will be reflected as unrealized depreciation on the underlying security for the period the put is held. Any gain on the sale of the underlying security will be reduced by the cost of the put.

There is a risk that the seller of an obligation with a put attached will not be able to repurchase the underlying obligation when (or if) a fund attempts to exercise the put. To minimize such risks, the funds will purchase obligations with puts attached only from sellers deemed creditworthy by the portfolio managers under the direction of the Board of Directors.

------

**Other Investment Companies**

Each of the One Choice Target Date Portfolios, One Choice Blend+ Portfolios, and One Choice Target Risk Portfolios may invest up to 100% of its total assets in other American Century Investments funds in reliance on Section 12(d)(1)(G) of the Investment Company Act of 1940.

Each of the underlying funds may invest in other investment companies, such as closed-end investment companies, unit investment trusts, exchange-traded funds (ETFs) and other open-end investment companies, provided that the investment is consistent with the fund's investment policies and restrictions. Under the Investment Company Act, each underlying fund's investment in such securities, subject to certain exceptions, currently is limited to:

(a)3% of the total voting stock of any one investment company,

(b)5% of the fund's total assets with respect to any one investment company; and

(c)10% of the fund's total assets in the aggregate.

A fund's investments in other investment companies may include money market funds managed by the advisor. Investments in money market funds are not subject to the percentage limitations set forth above.

As a shareholder of another investment company, a fund would bear, along with other shareholders, its pro rata portion of the other investment company's expenses, including advisory fees. These expenses would be in addition to the management fee that each fund bears directly in connection with its own operations.

ETFs are a type of fund bought and sold on a securities exchange. An ETF trades like common stock and may be actively managed or index-based. A fund may purchase an ETF to temporarily gain exposure to a portion of the U.S. or a foreign market while awaiting purchase of underlying securities, to gain exposure to specific asset classes or sectors, or as a substitute for investing directly in securities. The risks of owning an ETF generally reflect the risks of owning the underlying securities. Additionally, because the price of ETF shares is based on market price rather than net asset value (NAV), shares may trade at a price greater than NAV (a premium) or less than NAV (a discount). A fund may also incur brokerage commissions, as well as the cost of the bid/ask spread, when purchase or selling ETF shares.

**Repurchase Agreements**

Each fund may invest in repurchase agreements when they present an attractive short-term return on cash that is not otherwise committed to the purchase of securities pursuant to the investment policies of that fund. A repurchase agreement occurs when, at the time a fund purchases an interest-bearing obligation, the seller (a bank or a broker-dealer registered under the Securities Exchange Act of 1934) agrees to purchase it on a specified date in the future at an agreed-upon price. The repurchase price reflects an agreed-upon interest rate during the time the fund's money is invested in the security.

Because the security purchased constitutes collateral for the repurchase obligation, a repurchase agreement can be considered a loan collateralized by the security purchased. The fund's risk is the seller's ability to pay the agreed-upon repurchase price on the repurchase date. If the seller defaults, the fund may incur costs in disposing of the collateral, which would reduce the amount realized thereon. If the seller seeks relief under the bankruptcy laws, the disposition of the collateral may be delayed or limited. To the extent the value of the security decreases, the fund could experience a loss.

The funds will limit repurchase agreement transactions to securities issued by the U.S. government and its agencies and instrumentalities, and will enter into such transactions with those banks and securities dealers who are deemed creditworthy by the funds' advisor.

Repurchase agreements maturing in more than seven days would count toward a fund's 15% limit on illiquid securities.

**Restricted and Illiquid Securities** 

The funds may, from time to time, purchase restricted or illiquid securities, including Rule 144A securities, when they present attractive investment opportunities that otherwise meet the funds' criteria for selection. Restricted securities include securities that cannot be sold to the public without registration under the Securities Act of 1933 or the availability of an exemption from registration, or that are "not readily marketable" because they are subject to other legal or contractual delays in or restrictions on resale. Rule 144A securities are securities that are privately placed with and traded among qualified institutional investors rather than the general public. Although Rule 144A securities are considered restricted securities, they are not necessarily illiquid.

With respect to securities eligible for resale under Rule 144A, the advisor will determine the liquidity of such securities pursuant to the fund's Liquidity Risk Management Program, approved by the Board of Directors in accordance with Rule 22e-4.

Because the secondary market for such securities is limited to certain qualified institutional investors, the liquidity of such securities may be limited accordingly and a fund may, from time to time, hold a Rule 144A or other security that is illiquid. In such an event, the portfolio managers will consider appropriate remedies to minimize the effect on such fund's liquidity. Each fund may invest no more that 15% (5% for money market funds) of the value of its assets in illiquid securities.

------

**Short Sales**

A fund engages in short selling when it sells a security it does not own. To sell a security short, a fund must borrow the security from someone else to deliver it to the buyer. That fund then replaces the borrowed security by purchasing it at the market price at or before the time of replacement. Until it replaces the security, the fund repays the person that lent it the security for any interest or dividends that may have been paid or accrued during the period of the loan. Each fund may engage in short sales for cash management purposes only if, at the time of the short sale, the fund owns or has the right to acquire securities equivalent in kind and amount to the securities being sold short.

In short sale transactions, a fund's gain is limited to the price at which it sold the security short; its loss is limited only by the maximum price it must pay to acquire the security less the price at which the security was sold. In theory, losses from short sales may be unlimited. In order to borrow the security, a fund may be required to pay compensation to the lender for securities that are difficult to borrow due to demand or other factors. Short sales also cause a fund to incur brokerage fees and other transaction costs. Therefore, the amount of any gain a fund may receive from a short sale transaction is decreased and the amount of any loss increased by the amount of compensation to the lender, accrued interest or dividends and transaction costs a fund may be required to pay.

There is no guarantee that a fund will be able to close out a short position at any particular time or at a particular price. During the time that a fund is short a security, it is subject to the risk that the lender of the security will terminate the loan at a time when the fund is unable to borrow the same security from another lender. If that occurs, the fund may be "bought in" at the price required to purchase the security needed to close out the short position, which may be a disadvantageous price.

**Short-Term Securities**

The funds may invest a portion of their assets in money market and other short-term securities.

Examples of those securities include:

• Securities issued or guaranteed by the U.S. government and its agencies and instrumentalities

• Commercial Paper

• Certificates of Deposit and Euro Dollar Certificates of Deposit

• Bankers' Acceptances

• Short-term notes, bonds, debentures or other debt instruments

• Repurchase agreements

• Money market funds

**Structured Investments**

A structured investment is a security whose value or performance is linked to an underlying index or other security or asset class. Structured investments include asset-backed securities (ABS), commercial and residential mortgage-backed securities (MBS and CMBS), and collateralized mortgage obligations (CMO), which are described more fully below. Structured investments also include securities backed by other types of collateral. Structured investments involve the transfer of specified financial assets to a special purpose entity, generally a corporation or trust, or the deposit of financial assets with a custodian; and the issuance of securities or depositary receipts backed by, or representing interests in, those assets. Structured investments may be organized and operated to restructure the investment characteristics of the underlying security. The cash flow on the underlying instruments may be apportioned among the newly issued structured investments to create securities with different investment characteristics, such as varying maturities, payment priorities and interest rate provisions, and the extent of such payments made with respect to structured investments is dependent on the extent of the cash flow on the underlying instruments.

Structured investments are generally individually negotiated agreements or traded over the counter and, as such, there is no active trading market for such investments. Thus, structured investments may be less liquid than other securities. Because structured investments typically involve no credit enhancement, their credit risk generally will be equivalent to that of the underlying instruments. Structured investments are subject to such risks as the inability or unwillingness of the issuers of the underlying securities to repay principal and interest (credit risk), and requests by the issuers of the underlying securities to reschedule or restructure outstanding debt and to extend additional loan amounts (prepayment or extension risk).

**U.S. Government Securities** 

U.S. Treasury bills, notes, zero-coupon bonds and other bonds are direct obligations of the U.S. Treasury, which has never failed to pay interest and repay principal when due. Treasury bills have initial maturities of one year or less, Treasury notes from two to 10 years, and Treasury bonds more than 10 years. Although U.S. Treasury securities carry little principal risk if held to maturity, the prices of these securities (like all debt securities) change between issuance and maturity in response to fluctuating market interest rates.

------

Some U.S. government securities are supported by the direct full faith and credit pledge of the U.S. government; others are supported by the right of the issuer to borrow from the U.S. Treasury; others, such as securities issued by the Federal National Mortgage Association (FNMA), are supported by the discretionary authority of the U.S. government to purchase the agencies' obligations; and others are supported only by the credit of the issuing or guaranteeing instrumentality. There is no assurance that the U.S. government will provide financial support to an instrumentality it sponsors when it is not obligated by law to do so. Occasionally, Congressional negotiations regarding increasing the U.S. statutory debt ceiling cause uncertainty in the market. Uncertainty, or a default on U.S. government debt, could cause the credit rating of the U.S. government to be downgraded, increase volatility in debt and equity markets, result in higher interest rates, reduce prices of U.S. Treasury securities, or increase the costs of certain kinds of debt.

**Variable- and Floating-Rate Securities**

Interest rates on securities may be fixed for the term of the investment (fixed-rate securities) or tied to prevailing interest rates. Floating-rate instruments have interest rates that change whenever there is a change in a designated base rate; variable-rate instruments provide for specified periodic interest rate adjustments; auction-rate instruments have interest rates that are redetermined pursuant to an auction on specified dates.

Floating-rate securities frequently have caps limiting the extent to which coupon rates can be raised. The price of a floating-rate security may decline if its capped coupon rate is lower than prevailing market interest rates. Fixed- and floating-rate securities may be issued with a call date (which permits redemption before the maturity date). The exercise of a call may reduce an obligation's yield to maturity.

Interest rate resets on floating-rate U.S. government agency securities generally occur at intervals of one year or less in response to changes in a predetermined interest rate index. There are two main categories of indices: those based on U.S. Treasury securities and those derived from a calculated measure, such as a cost-of-funds index. Commonly used indices include the three-month, six-month and one-year Treasury bill rates; the two-year Treasury note yield; and the Eleventh District Federal Home Loan Bank Cost of Funds Index (EDCOFI). Fluctuations in the prices of floating-rate U.S. government agency securities are typically attributed to differences between the coupon rates on these securities and prevailing market interest rates between interest rate reset dates.

Variable - and floating - rate securities may be combined with a put or demand feature that permits the fund to demand payment of principal plus accrued interest from the issuer or a financial institution. Examples of VRDOs include variable-rate demand notes (VRDN) and variable-rate demand preferreds (VRDP). VRDNs combine a demand feature with an interest rate reset mechanism designed to result in a market value for the security that approximates par. VRDNs are generally designed to meet the requirements of money market fund Rule 2a-7. VRDPs are issued by a closed-end fund that in turn invests primarily in portfolios of bonds. They feature a floating rate dividend set via a weekly remarketing and have a fixed term, mandatory redemption, and an unconditional par put option.

**When-Issued and Forward Commitment Agreements**

The funds may sometimes purchase new issues of securities on a when-issued or forward commitment basis in which the transaction price and yield are each fixed at the time the commitment is made, but payment and delivery occur at a future date.

For example, a fund may sell a security and at the same time make a commitment to purchase the same or a comparable security at a future date and specified price. Conversely, a fund may purchase a security and at the same time make a commitment to sell the same or a comparable security at a future date and specified price. These types of transactions are executed simultaneously in what are known as dollar-rolls, buy/sell back transactions, cash and carry, or financing transactions. For example, a broker-dealer may seek to purchase a particular security that a fund owns. The fund will sell that security to the broker-dealer and simultaneously enter into a forward commitment agreement to buy it back at a future date. This type of transaction generates income for the fund if the dealer is willing to execute the transaction at a favorable price in order to acquire a specific security.

When purchasing securities on a when-issued or forward commitment basis, a fund assumes the rights and risks of ownership, including the risks of price and yield fluctuations. Market rates of interest on debt securities at the time of delivery may be higher or lower than those contracted for on the when-issued security. Accordingly, the value of that security may decline prior to delivery, which could result in a loss to the fund. While the fund will make commitments to purchase or sell securities with the intention of actually receiving or delivering them, it may sell the securities before the settlement date if doing so is deemed advisable as a matter of investment strategy.

To the extent a fund remains fully invested or almost fully invested at the same time it has purchased securities on a when-issued basis, there will be greater fluctuations in its net asset value than if it solely set aside cash to pay for when-issued securities. When the time comes to pay for the when-issued securities, the fund will meet its obligations with available cash, through the sale of securities, or, although it would not normally expect to do so, by selling the when-issued securities themselves (which may have a market value

------

greater or less than the fund's payment obligation). Selling securities to meet when-issued or forward commitment obligations may generate taxable capital gains or losses.

Generally, the funds intend to physically settle when-issued and forward commitments within 35 days of their trade dates. If such a transaction cannot be physically settled in this time, it will be treated as a derivatives transaction for purposes of the fund's derivative risk management program. The derivative risk management program is described in greater detail in the *Derivative Instruments* section.

**Zero-Coupon, Step-Coupon and Pay-In-Kind Securities**

Zero-coupon, step-coupon and pay-in-kind securities are debt securities that do not make regular cash interest payments. Zero-coupon and step-coupon securities are sold at a deep discount to their face value. Pay-in-kind securities pay interest through the issuance of additional securities. Because such securities do not pay current cash income, the price of these securities can be volatile when interest rates fluctuate. While these securities do not pay current cash income, federal income tax law requires the holders of zero-coupon, step-coupon and pay-in-kind securities to include in income each year the portion of the original issue discount and other noncash income on such securities accrued during that year. In order to continue to qualify for treatment as a regulated investment company under the Internal Revenue Code and avoid certain excise tax, the funds are required to make distributions of income accrued for each year. Accordingly, the funds may be required to dispose of other portfolio securities, which may occur in periods of adverse market prices, in order to generate cash to meet these distribution requirements.

**Investment Policies** 

Unless otherwise indicated, with the exception of the percentage limitations on borrowing, the policies described below apply at the time a fund enters into a transaction. Accordingly, any later increase or decrease beyond the specified limitation resulting from a change in a fund's assets will not be considered in determining whether it has complied with its investment policies.

**Fundamental Investment Policies**

The funds' fundamental investment policies are set forth below. These investment policies, a fund's status as diversified, and, except for One Choice 2060 Portfolio, One Choice 2065 Portfolio, One Choice 2070 Portfolio and the One Choice Blend+ Portfolios, a fund's investment objective set forth in its prospectus may not be changed without approval of a majority of the outstanding votes of shareholders of a fund. Under the Investment Company Act, the vote of a majority of the outstanding votes of shareholders means, the vote of (A) 67 percent or more of the voting securities present at a shareholder meeting, if the holders of more than 50 percent of the outstanding voting securities are present or represented by proxy; or (B) more than 50 percent of the outstanding voting securities, whichever is less.

|:---|:---|
| *Subject* | *Policy* |
| Senior Securities | A fund may not issue senior securities, except as permitted under the Investment Company Act. |
| Borrowing | A fund may not borrow money, except that a fund may borrow for temporary or emergency purposes (not for leveraging or investment) in an amount not exceeding 33⅓% of the fund's total assets (including the amount borrowed) less liabilities (other than borrowings). |
| Lending | A fund may not lend any security or make any other loan if, as a result, more than 33⅓% of the fund's total assets would be lent to other parties, except (i) through the purchase of debt securities in accordance with its investment objective, policies and limitations or (ii) by engaging in repurchase agreements with respect to portfolio securities. |
| Real Estate | A fund may not purchase or sell real estate unless acquired as a result of ownership of securities or other instruments. This policy shall not prevent a fund from investing in securities or other instruments backed by real estate or securities of companies that deal in real estate or are engaged in the real estate business. |
| Concentration | A fund may not concentrate its investments in securities of issuers in a particular industry (other than securities issued or guaranteed by the U.S. government or any of its agencies or instrumentalities, except that the funds will invest substantially all of their assets in investment companies that are members of the American Century Investments family of funds). |
| Underwriting | A fund may not act as an underwriter of securities issued by others, except to the extent that the fund may be considered an underwriter within the meaning of the Securities Act of 1933 in the disposition of restricted securities. |
| Commodities | A fund may not purchase or sell physical commodities unless acquired as a result of ownership of securities or other instruments, provided that this limitation shall not prohibit the fund from purchasing or selling options and futures contracts or from investing in securities or other instruments backed by physical commodities. |
| Control | A fund may not invest for purposes of exercising control over management. |

---

For purposes of the investment policy relating to senior securities, a fund may borrow from any bank provided that immediately after any such borrowing there is asset coverage of at least 300% for all borrowings of such fund. In the event that such asset coverage falls

------

below 300%, the fund shall, within three days thereafter (not including Sundays and holidays) or such longer period as the SEC may prescribe by rules and regulations, reduce the amount of its borrowings to an extent that the asset coverage of such borrowings is at least 300%.

For purposes of the investment policy relating to concentration, a fund shall not purchase any securities that would cause 25% or more of the value of the fund's net assets at the time of purchase to be invested in the securities of one or more issuers conducting their principal business activities in the same industry, provided that:

(a)there is no limitation with respect to investments in mutual funds,

(b)there is no limitation with respect to obligations issued or guaranteed by the U.S. government, any state, territory or possession of the United States, the District of Columbia or any of their authorities, agencies, instrumentalities or political subdivisions and repurchase agreements secured by such obligations (except that an Industrial Development Bond backed only by the assets and revenues of a non-governmental user will be deemed to be an investment in the industry represented by such user),

(c)wholly owned finance companies will be considered to be in the industries of their parents if their activities are primarily related to financing the activities of their parents,

(d)utilities will be divided according to their services, for example, gas, gas transmission, electric and gas, electric, and telephone will each be considered a separate industry, and

(e)personal credit and business credit businesses will be considered separate industries.

The funds consider the industries of the holdings of the other American Century funds (affiliated funds) in which they invest to assess industry concentration.

**Nonfundamental Investment Policies**

In addition, the funds are subject to the following investment policies that are not fundamental. These policies, along with the investment objective of the One Choice 2060 Portfolio, One Choice 2065 Portfolio, One Choice 2070 Portfolio and the One Choice Blend+ Portfolios, as set forth in their prospectus, may be changed by the Board of Directors.

---

| | |
|:---|:---|
| *Subject* | *Policy* |
| Leveraging | A fund may not purchase additional investment securities at any time during which outstanding borrowings exceed 5% of the total assets of the fund. |
| Liquidity | A fund may not purchase any security or enter into a repurchase agreement if, as a result, more than 15% of its net assets would be invested in illiquid securities. Illiquid securities include repurchase agreements not entitling the holder to payment of principal and interest within seven days, and securities that are illiquid by virtue of legal or contractual restrictions on resale or the absence of a readily available market. |
| Margin | A fund may not purchase securities on margin, except to obtain such short-term credits as are necessary for the clearance of transactions, and provided that margin payments and other deposits in connection with transactions involving futures, options (puts, calls, etc.), swaps, short sales, forward contracts, commitment agreements, and other similar investment techniques shall not be deemed to constitute purchasing securities on margin. |
| Futures &<br>Options | A fund may enter into futures contracts, and write and buy put and call options relating to futures contracts. A fund may not, however, enter into leveraged futures transactions if it would be possible for the fund to lose more than the notional value of the investment. |
| Issuers with<br>Limited<br>Operating<br>Histories | A fund may invest up to 5% of its assets in the equity securities of issuers with limited operating histories. An issuer is considered to have a limited operating history if that issuer has a record of less than three years of continuous operation. Periods of capital formation, incubation, consolidations, and research and development may be considered in determining whether a particular issuer has a record of three years of continuous operation. For purposes of this limitation, "issuers" refers to operating companies that issue securities for the purpose of issuing debt or raising capital as a means of financing their ongoing operations. |

---

The Investment Company Act imposes certain additional restrictions upon the funds' ability to acquire securities issued by insurance companies, broker-dealers, underwriters or investment advisors, and upon transactions with affiliated persons as defined by the Act. It also defines and forbids the creation of cross and circular ownership.

**Portfolio Turnover**

The portfolio turnover rate of each fund for its most recent fiscal year is included in the *Fund Summary* section of that fund's prospectus. The portfolio turnover rate for each fund's last five fiscal years (or a shorter period if the fund is less than five years old) is shown in the *Financial Highlights* tables in the prospectus.

Variations in a fund's portfolio turnover rate from year to year may be due to a fluctuating volume of shareholder purchase and redemption activity, varying market conditions and/or changes in the managers' investment outlook.

------

The funds will, under most circumstances, be essentially fully invested in other American Century Investments mutual funds within the allocation framework set forth in the prospectuses. The portfolio managers may sell shares of the underlying funds without regard to the length of time they have been held. A high level of turnover is not anticipated beyond that necessary to accommodate purchases and sales of each fund's shares and to implement periodic asset rebalancings and reallocations. Details about the underlying funds' portfolio turnover rates appear in those funds' prospectuses and statements of additional information.

**Disclosure of Portfolio Holdings**

The advisor (ACIM) has adopted policies and procedures with respect to the disclosure of fund portfolio holdings and characteristics, which are described below.

**Distribution to the Public**

The funds invest substantially all of their assets in other American Century Investments mutual funds. These holdings, as described in the funds' prospectuses, are available at any time with no lag period. In addition, full portfolio holdings for each fund are disclosed in the annual and semiannual shareholder reports and the quarter-end portfolio disclosures on Form N-PORT. Such disclosures are filed with the Securities and Exchange Commission within 60 days of each fiscal quarter end and also posted on americancentury.com at approximately the same time the filings are made.

The advisor makes no distinction among different categories of recipients, such as individual investors, institutional investors, intermediaries that distribute the funds' shares, third-party service providers, rating and ranking organizations, and fund affiliates. Because this information is publicly available and widely disseminated, the advisor places no conditions or restrictions on, and does not monitor, its use. Nor does the advisor require special authorization for its disclosure.

Neither the advisor nor the funds receive any compensation from any party for the distribution of portfolio holdings information.

The advisor reserves the right to change its policies and procedures with respect to the distribution of portfolio holdings information at any time. There is no guarantee that these policies and procedures will protect the funds from the potential misuse of holdings information by individuals or firms in possession of such information.

**Management**

**The Board of Directors**

The individuals listed below serve as directors of the funds. Each director will continue to serve in this capacity until death, retirement, resignation or removal from office. The board has adopted a mandatory retirement age for directors who are not "interested persons," as that term is defined in the Investment Company Act (independent directors). Independent directors shall retire on December 31 of the year in which they reach their 75th birthday.

Jonathan S. Thomas is an "interested person" because he currently serves as President and Chief Executive Officer of American Century Companies, Inc. (ACC), the parent company of American Century Investment Management, Inc. (ACIM or the advisor). The other directors (more than three-fourths of the total number) are independent. They are not employees, directors or officers of, and have no financial interest in, ACC or any of its wholly owned, direct or indirect, subsidiaries, including ACIM, American Century Investment Services, Inc. (ACIS) and American Century Services, LLC (ACS), and they do not have any other affiliations, positions or relationships that would cause them to be considered "interested persons" under the Investment Company Act. The directors serve in this capacity for seven (in the case of Jonathan S. Thomas, 16; and Thomas W. Bunn, 8) registered investment companies in the American Century Investments family of funds.

The following table presents additional information about the directors. The mailing address for each director is 4500 Main Street, Kansas City, Missouri 64111.

**Qualifications of Directors**

Generally, no one factor was decisive in the selection of the directors to the board. Qualifications considered by the board to be important to the selection and retention of directors include the following: (i) the individual's business and professional experience and accomplishments; (ii) the individual's educational background and accomplishments; (iii) the individual's experience and expertise performing senior policy-making functions in business, government, education, accounting, law and/or administration; (iv) how the individual's expertise and experience would contribute to the mix of relevant skills and experience on the board; (v) the individual's ability to work effectively with the other members of the board; and (vi) the individual's ability and willingness to make the time commitment necessary to serve as an effective director. In addition, the individuals' ability to review and critically evaluate information, their ability to evaluate fund service providers, their ability to exercise good business judgment on behalf of fund shareholders, their prior service on the board, and their familiarity with the funds are considered important assets.

------

When assessing potential new directors, the board has a policy of considering individuals from various and diverse backgrounds. Such diverse backgrounds may include differences in professional experience, education, individual skill sets and other individual attributes. Additional information about each director's individual educational and professional experience (supplementing the information provided in the table above) follows and was considered as part of his or her nomination to, or retention on, the board.

**Responsibilities of the Board** 

The board is responsible for overseeing the advisor's management and operations of the funds pursuant to the management agreements. Directors also have significant responsibilities under the federal securities laws. Among other things, they:

• oversee the performance of the funds;

• oversee the quality of the advisory and shareholder services provided by the advisor and other service providers to the funds;

• review annually the fees paid to the advisor for its services;

• monitor potential conflicts of interest between the funds and their affiliates, including the advisor;

• oversee custody of assets and the valuation of securities; and

• oversee the funds' compliance program.

In performing their duties, board members receive detailed information about the funds, the advisor and other service providers to the funds regularly throughout the year, and meet at least quarterly with management of the advisor to review reports about fund operations. The directors' role is to provide oversight and not to provide day-to-day management.

The board has all powers necessary or convenient to carry out its responsibilities. Consequently, the board may adopt bylaws providing for the regulation and management of the affairs of the funds and may amend and repeal them to the extent that such bylaws do not reserve that right to the funds' shareholders. They may increase or reduce the number of board members and may, subject to the Investment Company Act, fill board vacancies. Board members also may elect and remove such officers and appoint and terminate such agents as they consider appropriate. They may establish and terminate committees consisting of two or more directors who may exercise the powers and authority of the board as determined by the directors. They may, in general, delegate such authority as they

------

consider desirable to any officer of the funds, to any board committee and to any agent or employee of the funds or to any custodian, transfer agent, investor servicing agent, principal underwriter or other service provider for a fund.

To communicate with the board, or a member of the board, a shareholder should send a written communication addressed to the attention of the corporate secretary (the "Corporate Secretary") at American Century funds, P.O. Box 418210, Kansas City, Missouri 64141-9210. Shareholders who prefer to communicate by email may send their comments to corporatesecretary@americancentury.com. The Corporate Secretary will forward all such communications to each member of the Compliance and Shareholder Services Committee, or if applicable, the individual director(s) and/or committee chair named in the correspondence. However, if a shareholder communication is addressed exclusively to the funds' independent directors, the Corporate Secretary will forward the communication to the Compliance and Shareholder Services Committee chair, who will determine the appropriate action.

**Board Leadership Structure and Standing Board Committees** 

Jan M. Lewis currently serves as the independent board chair and has served in such capacity since 2022. All of the board's members except for Jonathan S. Thomas are independent directors. The independent directors meet separately, as needed and at least in conjunction with each quarterly meeting of the board, to consider a variety of matters that are scheduled to come before the board and meet periodically with the funds' Chief Compliance Officer and fund auditors. They are advised by independent legal counsel. No independent director may serve as an officer or employee of a fund. The board has also established several committees, as described below. The board believes that the current leadership structure, with independent directors filling all but one position on the board, with an independent director serving as board chair, and with the board committees comprised only of independent directors is appropriate and allows for independent oversight of the funds.

The board has an Audit Committee that approves the funds' (or corporation's) engagement of the independent registered public accounting firm and recommends approval of such engagement to the independent directors. The committee also oversees the activities of the accounting firm, receives regular reports regarding fund accounting, oversees securities valuation (approving the funds' valuation policy and receiving reports regarding instances of fair valuation thereunder) and receives regular reports from the advisor's internal audit department. The committee currently consists of Chris H. Cheesman (chair), Barry Fink, Lynn Jenkins and Gary C. Meltzer. The committee met [four] times during the funds' previous fiscal year ended July 31, 2025.

The board has a Governance Committee that is responsible for reviewing board procedures and committee structures. The committee also considers and recommends individuals for nomination as directors, and may recommend the creation of new committees. The names of potential director candidates may be drawn from a number of sources, including members of the board, management and shareholders. Shareholders may submit director nominations at any time to the Corporate Secretary, American Century funds, P.O. Box 418210, Kansas City, MO 64141-9210. When submitting nominations, shareholders should include the name, age and address of the candidate, as well as a detailed resume of the candidate's qualifications and a signed statement from the candidate of his/her willingness to serve on the board. Shareholders submitting nominations should also include information concerning the number of fund shares and length of time held by the shareholder, and if applicable, similar information for the potential candidate. All nominations submitted by shareholders will be forwarded to the chair of the Governance Committee for consideration. The Corporate Secretary will maintain copies of such materials for future reference by the committee when filling board positions.

If this process yields more than one desirable candidate, the committee will rank them by order of preference depending on their qualifications and the funds' needs. The candidate(s) may then be contacted to evaluate their interest and be interviewed by the full committee. Based upon its evaluation and any appropriate background checks, the committee will decide whether to recommend a candidate's nomination to the board.

The Governance Committee also may recommend the creation of new committees, evaluate the membership structure of new and existing committees, consider the frequency and duration of board and committee meetings and otherwise evaluate the responsibilities, processes, resources, performance and compensation of the board. The committee currently consists of Barry Fink (chair), Brian Bulatao, Lynn Jenkins, Jan M. Lewis and Gary C. Meltzer. The committee met [three] times during the funds' previous fiscal year ended July 31, 2025.

The board also has a Compliance and Shareholder Services Committee, which reviews the results of the funds' compliance testing program, meets regularly with the funds' Chief Compliance Officer, reviews shareholder communications, reviews quarterly reports regarding the quality of shareholder service provided by the advisor, and monitors implementation of the funds' Code of Ethics. The committee currently consists of Thomas W. Bunn (chair), Brian Bulatao, Rajesh K. Gupta and Jan M. Lewis. The committee met [four] times during the funds' previous fiscal year ended July 31, 2025.

The board has a Fund Performance Review Committee that meets quarterly to review the investment activities and strategies used to manage fund assets and monitor investment performance. The committee regularly receives reports from the advisor's chief investment officer, portfolio managers and other investment personnel concerning the funds' efforts to achieve their investment objectives. The committee also receives information regarding fund trading activities and monitors derivative usage. The committee does not review individual security selections. The committee currently consists of Rajesh K. Gupta (chair), Brian Bulatao, Thomas

------

W. Bunn, Chris H. Cheesman, Barry Fink, Lynn Jenkins, Jan M. Lewis and Gary C. Meltzer. The committee met [four] times during the funds' previous fiscal year ended July 31, 2025.

**Risk Oversight by the Board** 

As previously disclosed, the board oversees the advisor's management of the funds and meets at least quarterly with management of the advisor to review reports and receive information regarding fund operations. Risk oversight relating to the funds is one component of the board's oversight and is undertaken in connection with the duties of the board. As described above, the board's committees assist the board in overseeing various types of risks relating to the funds, including, but not limited to, investment risk, operational risk and enterprise risk. The board receives regular reports from each committee regarding the committee's areas of oversight responsibility and, through those reports and its regular interactions with management of the advisor during and between meetings, provides oversight of the advisor's risk management processes. In addition, the board receives information regarding, and has discussions with senior management of the advisor about, the advisor's enterprise risk management systems and strategies, including an annual review of the advisor's risk management practices. There can be no assurance that all elements of risk, or even all elements of material risk, will be disclosed to or identified by the board, or that the advisor's risk management systems and strategies, and the board's oversight thereof, will mitigate all elements of risk, or even all elements of material risk to the funds.

**Board Compensation** 

Each independent director receives compensation for service as a member of the board. Under the terms of each management agreement with the advisor, the funds are responsible for paying such fees and expenses. None of the interested directors or officers of the funds receive compensation from the funds. For the fiscal year ended July 31, 2025, each independent director received the following compensation for his or her service to the funds and the American Century Investments family of funds.

<sup>1&nbsp;&nbsp;&nbsp;&nbsp;</sup> *Includes compensation paid to the directors for the fiscal year ended July 31, 2025, and also includes amounts deferred at the election of the directors under the American Century Mutual Funds' Independent Directors' Deferred Compensation Plan.*

<sup>2&nbsp;&nbsp;&nbsp;&nbsp;</sup> *Includes compensation paid to each director for his or her service as director/trustee for seven (in the case of Mr. Bunn, eight) investment companies in the American Century Investments family of funds. The total amount of deferred compensation included in the table is as follows: Mr. Bunn, [$]; and Ms. Jenkins, [$].*

*3 Mr. Yates retired from the board on December 31, 2023.*

None of the funds currently provides any pension or retirement benefits to the directors except pursuant to the American Century Mutual Funds' Independent Directors' Deferred Compensation Plan adopted by the corporation. Under the plan, the independent directors may defer receipt of all or any part of the fees to be paid to them for serving as directors of the funds. All deferred fees are credited to accounts established in the names of the directors. The amounts credited to each account then increase or decrease, as the case may be, in accordance with the performance of one or more American Century funds selected by the directors. The account balance continues to fluctuate in accordance with the performance of the selected fund or funds until final payment of all amounts credited to the account. Directors are allowed to change their designation of funds from time to time.

Generally, deferred fees are not payable to a director until the distribution date elected by the director in accordance with the terms of the plan. Such distribution date may be a date on or after the director's retirement date, but may be an earlier date if the director agrees not to make any additional deferrals after such distribution date. Distributions may commence prior to the elected payment date for certain reasons specified in the plan, such as unforeseeable emergencies, death or disability. Directors may receive deferred fee account balances either in a lump sum payment or in substantially equal installment payments to be made over a period not to exceed 10 years. Upon the death of a director, all remaining deferred fee account balances are paid to the director's beneficiary or, if none, to the director's estate.

------

The plan is an unfunded plan and, accordingly, the funds have no obligation to segregate assets to secure or fund the deferred fees. To date, the funds have met all payment obligations under the plan. The rights of directors to receive their deferred fee account balances are the same as the rights of a general unsecured creditor of the funds. The plan may be terminated at any time by the administrative committee of the plan. If terminated, all deferred fee account balances will be paid in a lump sum.

**Ownership of Fund Shares**

The directors owned shares in the funds as of December 31, 2024, as shown in the table below. Because One Choice 2070 Portfolio and One Choice Blend+ 2070 Portfolio are new, they are not included in the table.

**Code of Ethics**

The funds, their investment advisor and principal underwriter have adopted codes of ethics under Rule 17j-1 of the Investment Company Act. They permit personnel subject to the codes to invest in securities, including securities that may be purchased or held by the underlying funds, provided that they first obtain approval from the compliance department before making such investments.

**Proxy Voting Policies** 

The advisor is responsible for exercising the voting rights associated with the securities purchased and/or held by the funds. The funds' Board of Directors has approved the advisor's proxy voting policies to govern the advisor's proxy voting activities.

A copy of the advisor's proxy voting policies is attached hereto as *Appendix D*. Information regarding how the advisor voted proxies relating to portfolio securities during the most recent 12-month period ended June 30, is available at americancentury.com/docs or may be requested free of charge by calling toll-free at 1-800-345-2021.

The funds have no employees. To conduct the funds' day-to-day activities, the corporation has hired a number of service providers. Each service provider has a specific function to fill on behalf of the funds that is described below.

ACIM, ACS and ACIS are wholly owned, directly or indirectly, by ACC.

SIMR is part of a not-for-profit biomedical research organization dedicated to finding the keys to the causes, treatments and prevention of disease.

**Investment Advisor**

American Century Investment Management, Inc. (ACIM) serves as the investment advisor for each of the funds. A description of the responsibilities of the advisor appears in each prospectus under the heading *Management.*

The advisor does not receive a unified management fee for services provided to the following funds: One Choice Portfolio: Very Conservative, One Choice Portfolio: Conservative, One Choice Portfolio: Moderate, One Choice Portfolio: Aggressive and One Choice Portfolio: Very Aggressive.

Each class of each fund and underlying fund is subject to a contractual unified management fee based on a percentage of the daily net assets of such class. For more information about the unified management fee, see *The Investment Advisor* under the heading *Management* in each fund's prospectus. The amount of the fee is calculated daily and paid monthly in arrears.

The management fee rates for the funds as of the date of this statement of additional information appear below.

<sup>1&nbsp;&nbsp;&nbsp;&nbsp;</sup>*Each year, the Board of Directors will approve a new management fee rate. The fee rate will be based on the most conservative (i.e., least expensive) neutral mix of the underlying funds estimated by the portfolio managers for the upcoming year, and adjusted for each class to reflect such class's separate arrangements for shareholder services. Because the fee rates are based on the neutral mix, it is possible for them to increase from one year to the next.*

On each calendar day, each class of each fund accrues a management fee that is equal to the class's management fee rate times the net assets of the class divided by 365 (366 in leap years). On the first business day of each month, the funds pay a management fee to the advisor for the previous month. The fee for the previous month is the sum of the calculated daily fees for each class of a fund during the previous month.

The management agreement between the corporation and the advisor shall continue in effect for a period of two years from its effective date (unless sooner terminated in accordance with its terms) and shall continue in effect from year to year thereafter for each fund so long as such continuance is approved at least annually by:

(1)either the funds' Board of Directors, or a majority of the outstanding voting securities of such fund (as defined in the Investment Company Act) and

(2)the vote of a majority of the directors of the funds who are not parties to the agreement or interested persons of the advisor, cast in person at a meeting called for the purpose of voting on such approval.

The management agreement states that the funds' Board of Directors or a majority of the outstanding voting securities of each class of such fund may terminate the management agreement at any time without payment of any penalty on 60 days' written notice to the advisor. The management agreement shall be automatically terminated if it is assigned.

The management agreement states that the advisor shall not be liable to the funds or their shareholders for anything other than willful misfeasance, bad faith, gross negligence or reckless disregard of its obligations and duties.

The management agreement also provides that the advisor and its officers, directors and employees may engage in other business, render services to others, and devote time and attention to any other business whether of a similar or dissimilar nature.

Certain investments may be appropriate for the funds and also for other clients advised by the advisor. Investment decisions for the funds and other clients are made with a view to achieving their respective investment objectives after consideration of such factors as their current holdings, availability of cash for investment and the size of their investment generally. A particular security may be bought or sold for only one client or fund, or in different amounts and at different times for more than one but less than all clients or funds. A particular security may be bought for one client or fund on the same day it is sold for another client or fund, and a client or fund may hold a short position in a particular security at the same time another client or fund holds a long position. In addition, purchases or sales of the same security may be made for two or more clients or funds on the same date. The advisor has adopted procedures designed to ensure such transactions will be allocated among clients and funds in a manner believed by the advisor to be equitable to each. In some cases this procedure could have an adverse effect on the price or amount of the securities purchased or sold by a fund.

Unified management fees incurred by each fund for the fiscal periods ended July 31, 2025, 2024 and 2023 are indicated in the following table. Because One Choice 2070 Portfolio and One Choice Blend+ 2070 Portfolio are new, they are not included in the table below. **[Table to be updated]**

**Potential Conflicts of Interest**

Certain conflicts of interest may arise in connection with American Century Investments' management of client portfolios with different investment strategies. Potential conflicts can include, for example, one investment strategy buying or selling a security while another has a different, potentially opposite, position in the same security. This may include one investment strategy taking a short position in the security of an issuer that is held long in another investment strategy (or vice versa). Other potential conflicts may arise with respect to the allocation of investment opportunities across client portfolios, which are discussed in more detail below. American Century Investments has adopted policies and procedures that are designed to minimize the effects of these conflicts.

Management of American Century Investments' client portfolios is organized according to investment discipline and investment strategy. Investment disciplines include, for example, Disciplined Equity, Global Growth Equity (both U.S. and Global/Non-U.S.), Global Value Equity, Global Fixed Income, Multi-Asset Strategies, American Century Rules-Based ETF strategies, Avantis Investors strategies, and Private Investments. Within each investment discipline are one or more portfolio teams responsible for managing specific investment strategies, such as U.S. Disciplined Core Value, U.S. Small Cap Value, U.S. Large Cap Growth, Emerging Markets Equity and U.S. Core Fixed Income. In some cases, a portfolio manager or team may be responsible for managing (or assisting in managing) multiple investment strategies within or across investment disciplines. Generally, client portfolios with similar investment strategies are managed by the same portfolio management team using similar investment objectives, approaches and philosophies. Accordingly, portfolio holdings, position sizes, and industry and sector exposures tend to be similar across client

------

portfolios with similar investment strategies, which minimizes the potential for conflicts of interest. In addition, American Century Investments maintains information barriers that restrict portfolio management teams within an investment discipline from having access to information regarding security positions, orders or transactions in client portfolios or investment strategies in other investment disciplines. If a portfolio manager or team manages or assists in managing an investment strategy in another investment discipline, that portfolio manager or team will only have access to information relating to that investment strategy and not other investment strategies within that investment discipline. The information barriers are intended to aid in preventing the misuse of portfolio holdings information or trading activity in other investment disciplines. Portfolio managers or teams that manage (or assist in managing) investment strategies across investment disciplines will not allow their access to portfolio holdings and/or trading information in one investment discipline to in any way impact decisions they make for client portfolios in other investment disciplines.

For each investment strategy, one portfolio is generally designated as the "policy portfolio." Other portfolios with similar investment objectives, guidelines and restrictions, if any, are referred to as "tracking portfolios." When managing policy and tracking portfolios, a portfolio team typically purchases and sells securities across all portfolios that the team manages. American Century Investments' trading systems include various order entry programs that assist in the management of multiple portfolios, such as the ability to purchase or sell the same relative amount of one security across several funds. In some cases a tracking portfolio may have additional restrictions or limitations that cause it to be managed separately from the policy portfolio. Portfolio managers make purchase and sale decisions for such portfolios alongside the policy portfolio to the extent the overlap is appropriate, and separately, if the overlap is not.

American Century Investments may aggregate orders to purchase or sell the same security for multiple portfolios when it believes such aggregation is consistent with its duty to seek best execution on behalf of its clients. American Century does not aggregate orders where aggregation is not appropriate or practicable from its operational or other perspectives. For example, limit orders, orders for the same security with different priority codes, cash flows, separate trading desks, or portfolio management processes may, among other factors, result in separate, non-aggregated trades. In addition, orders of certain client portfolios may, by investment restriction or otherwise, be determined not to be available for aggregation. American Century Investments has adopted policies and procedures to minimize the risk that a client portfolio could be systematically advantaged or disadvantaged in connection with the aggregation of orders.

American Century Investments generally allocates securities purchased or sold in an aggregated transaction among participating client accounts *pro rata* based on order size. In certain situations, however, a *pro rata* allocation of the securities or proceeds may not be possible or desirable. In these cases, American Century Investments will decide how to allocate the securities or proceeds according to each account's particular circumstances and needs and in a manner that American Century Investments believes is fair and equitable to clients over time in light of factors based on a good faith assessment of the investment opportunity relative to the objectives, limitations, and requirements of each eligible client account. Relevant factors may include, without limitation, client-specific considerations, rebalancing needs, and minimum denomination of increments and round lot considerations. In addition, if American Century Investments is unable to execute fully an aggregated transaction and determines that it would be impractical to allocate a small number of securities on a *pro rata* basis among the participating accounts, American Century Investments allocates the securities in a manner it determines to be fair to all accounts over time. Thus, in some cases it is possible that the application of the factors described herein may result in allocations in which certain client accounts participating in an aggregated transaction may receive an allocation when other accounts do not.

Because initial public offerings (IPOs) are usually available in limited supply and in amounts too small to permit across-the-board *pro rata* allocations, American Century Investments has adopted special procedures designed to promote a fair and equitable allocation of IPO securities among clients over time.

The advisor monitors all trading activity for best execution and to make sure no set of clients is being systematically disadvantaged.

Finally, investment of American Century Investments' corporate assets in proprietary accounts may raise additional conflicts of interest. To mitigate these potential conflicts of interest, American Century Investments has adopted policies and procedures intended to provide that trading in proprietary accounts is performed in a manner that does not give improper advantage to American Century Investments to the detriment of client portfolios.

**Compensation**

American Century Investments portfolio manager compensation is structured to align the interests of portfolio managers with those of the shareholders whose assets they manage. As of July 31, 2025, it includes the components described below, each of which is determined with reference to a number of factors such as overall performance, market competition, and internal equity.

***Base Salary***

Portfolio managers receive base pay in the form of a fixed annual salary.

***Bonus***

A significant portion of portfolio manager compensation takes the form of an annual incentive bonus which is determined by a combination of factors. One factor is investment performance. The mutual funds' investment performance is generally measured by a combination of one-, three- and five-year pre-tax performance relative to various benchmarks and/or internally-customized peer

------

groups, as indicated below. Each fund constructs its custom peer group using all the funds in the category indicated below as a starting point. Funds are then eliminated from the peer group based on a standardized methodology designed to result in a final peer group that is both more stable (i.e., has less peer turnover) over the long term and that more closely represents the fund's true peers based on internal investment mandates.

The performance comparison periods may be adjusted based on a fund's inception date or a portfolio manager's tenure on the fund. Because One Choice 2070 Portfolio and One Choice Blend+ 2070 Portfolio are new, they are not included in the table below.

<sup>1</sup>*&nbsp;&nbsp;&nbsp;&nbsp;Effective January 1, 2018, the fund's benchmark was changed from S&P Target Date To 2055+.*

<sup>2</sup> *Effective October 1, 2021, the fund's benchmark was changed from S&P Target Date To 2060+.*

<sup>3&nbsp;&nbsp;&nbsp;&nbsp;</sup>*The fund's benchmark is a custom benchmark comprised of the various benchmarks of the underlying funds (weighted according to such fund's asset mix).*

Portfolio managers may have responsibility for multiple American Century Investments mutual funds. In such cases, the performance of each is assigned a percentage weight appropriate for the portfolio manager's relative levels of responsibility. Portfolio managers also may have responsibility for other types of managed portfolios or ETFs. If the performance of a managed account or ETF is considered for purposes of compensation, it is generally measured via the same criteria as an American Century Investments mutual fund (i.e., relative to the performance of a benchmark and/or peer group).

A second factor in the bonus calculation relates to the performance of a number of American Century Investments mutual funds managed according to one of the following investment disciplines: global growth equity, global value equity, disciplined equity, global fixed-income, and multi-asset strategies. The performance of American Century ETFs may also be included for certain investment disciplines. Performance is measured for each product individually as described above and then combined to create an overall composite for the product group. These composites may measure one-year performance (equal weighted) or a combination of one-, three- and five-year performance (equal or asset weighted) depending on the portfolio manager's responsibilities and products

------

managed and the composite for certain portfolio managers may include multiple disciplines. This feature is designed to encourage effective teamwork among portfolio management teams in achieving long-term investment success for similarly styled portfolios.

A portion of portfolio managers' bonuses may be discretionary and may be tied to factors such as profitability or individual performance goals, such as research projects and/or the development of new products.

***Restricted Stock Plans***

Portfolio managers are eligible for grants of restricted stock of ACC. These grants are discretionary, and eligibility and availability can vary from year to year. The size of an individual's grant is determined by individual and product performance as well as other product-specific considerations such as profitability. Grants can appreciate/depreciate in value based on the performance of the ACC stock during the restriction period (generally three to four years).

***Deferred Compensation Plans***

Portfolio managers are eligible for grants of deferred compensation. These grants are used in very limited situations, primarily for retention purposes. Grants are fixed and can appreciate/depreciate in value based on the performance of the American Century Investments mutual funds in which the portfolio manager chooses to invest them.

**Ownership of Securities**

The following table indicates the dollar range of securities of each fund beneficially owned by the fund's portfolio managers as of July 31, 2025, the fund's most recent fiscal year end. Certain portfolio managers serve on teams that oversee a number of funds in the same broad investment strategy and are not expected to invest in each fund . Because One Choice 2070 Portfolio and One Choice Blend+ 2070 Portfolio are new, they are not included in the table below. **[Table to be updated]**

**Transfer Agent and Administrator**

American Century Services, LLC (ACS), 4500 Main Street, Kansas City, Missouri 64111, serves as transfer agent and dividend-paying agent for the funds. It provides physical facilities, computer hardware and software and personnel for the day-to-day administration of the funds and the advisor, including the maintenance of the funds' underlying fund shares in its book entry transfer agency system. The advisor pays ACS's costs for serving as transfer agent and dividend-paying agent for the funds out of the advisor's fees. For a description of these fees and the terms of payment, see the discussion under the caption *Investment Advisor,* on page 34.

Proceeds from purchases of fund shares may pass through accounts maintained by the transfer agent at Commerce Bank, N.A. or UMB Bank, n.a. before being held at the fund's custodian. Redemption proceeds also may pass from the custodian to the shareholder through such bank accounts.

From time to time, special services may be offered to shareholders who maintain higher share balances in our family of funds. These services may include the waiver of minimum investment requirements, expedited confirmation of shareholder transactions, newsletters and a team of personal representatives. Any expenses associated with these special services will be paid by the advisor.

**Sub-Administrator**

The advisor has entered into an Administration Agreement with State Street Bank and Trust Company (SSB) to provide certain fund accounting, fund financial reporting, tax and treasury/tax compliance services for the funds, including striking the daily net asset value for each fund. The advisor pays SSB a monthly fee as compensation for these services that is based on the total net assets of accounts in the American Century complex serviced by SSB. ACS does pay SSB for some additional services on a per fund basis. While ACS continues to serve as the administrator of the funds, SSB provides sub-administrative services that were previously undertaken by ACS.

**Distributor**

The funds' shares are distributed by American Century Investment Services, Inc. (ACIS), a registered broker-dealer. The distributor is a wholly owned subsidiary of ACC and its principal business address is 4500 Main Street, Kansas City, Missouri 64111.

The distributor is the principal underwriter of the funds' shares. The distributor makes a continuous, best-efforts underwriting of the funds' shares. This means the distributor has no liability for unsold shares. The advisor pays ACIS's costs for serving as principal underwriter of the funds' shares out of the advisor's fees. For a description of these fees and the terms of payment, see the discussion under the caption *Investment Advisor*, on page 34. ACIS does not earn commissions for distributing the funds' shares.

Certain financial intermediaries unaffiliated with the distributor or the funds may perform various administrative and shareholder services for their clients who are invested in the funds. These services may include assisting with fund purchases, redemptions and exchanges, distributing information about the funds and their performance, preparing and distributing client account statements, and other administrative and shareholder services that would otherwise be provided by the distributor or its affiliates. The distributor may pay fees out of its own resources to such financial intermediaries for providing these services.

**Custodian Bank**

State Street Bank and Trust Company (SSB), One Congress Street, Suite 1, Boston, Massachusetts 02114-2016 serves as custodian of the funds' cash and securities under a Master Custodian Agreement with the corporation. The custodian takes no part in determining the investment policies of the funds or in deciding which securities are purchased or sold by the funds. The underlying funds, however, may invest in certain obligations of the custodian and may purchase or sell certain securities from or to the custodian.

**Independent Registered Public Accounting Firm**

Deloitte & Touche LLP is the independent registered public accounting firm of the funds. The address of Deloitte & Touche LLP is 1100 Walnut Street, Kansas City, Missouri 64106. As the independent registered public accounting firm of the funds, Deloitte & Touche LLP provides services including auditing the annual financial statements and financial highlights for each fund.

------

**Brokerage Allocation**

The funds generally will purchase and sell their portfolio securities (i.e., shares of the underlying American Century Investments mutual funds) by dealing directly with the issuers, the underlying funds. As a result, the funds are not expected to incur brokerage costs directly other than transaction costs associated with purchasing exchange-traded funds (applicable to the One Choice Blend+ Portfolios).

In the fiscal years ended July 31, 2025, 2024 and 2023, the funds paid the following brokerage commissions including, as applicable, futures commissions. **[Table to be updated]**

Details about brokerage commissions paid by the underlying funds appear in those funds' statements of additional information.

**Information About Fund Shares**

Each of the funds named on the front of this statement of additional information is a series of shares issued by the corporation, and shares of each fund have equal voting rights. In addition, each series (or fund) may be divided into separate classes. See *Multiple Class Structure,* which follows. Additional funds and classes may be added without a shareholder vote.

Each fund votes separately on matters affecting that fund exclusively. Voting rights are not cumulative, so investors holding more than 50% of the corporation's (all funds') outstanding shares may be able to elect a Board of Directors. The corporation undertakes dollar-based voting, meaning that the number of votes a shareholder is entitled to is based upon the dollar amount of the shareholder's investment. The election of directors is determined by the votes received from all of the corporation's shareholders without regard to whether a majority of shares of any one fund voted in favor of a particular nominee or all nominees as a group.

The assets belonging to each series are held separately by the custodian and the shares of each series or class represent a beneficial interest in the principal, earnings and profit (or losses) of investments and other assets held for each series or class. Within their respective series or class, all shares have equal redemption rights. Each share, when issued, is fully paid and non-assessable.

Each shareholder has rights to dividends and distributions declared by the fund he or she owns and to the net assets of such fund upon its liquidation or dissolution proportionate to his or her share ownership interest in the fund.

**Multiple Class Structure**

The corporation's Board of Directors has adopted a multiple class plan pursuant to Rule 18f-3 under the Investment Company Act. The plan is described in the prospectus of any fund that offers more than one class. Pursuant to such plan, the funds may issue the following classes of shares: Investor Class, I Class, A Class, C Class, R Class and R6 Class. Not all funds offer all classes.

The Investor Class is made available to investors directly from American Century Investments and/or through some financial intermediaries. Additional information regarding eligibility for Investor Class shares may be found in the funds' prospectuses. The I Class is made available to institutional shareholders or through financial intermediaries that provide various shareholder and administrative services. The A and C Classes also are made available through financial intermediaries, for purchase by individual investors who receive advisory and personal services from the intermediary. The R Class is made available through financial intermediaries and is generally used in 401(k) and other retirement plans. The R6 Class is generally available only to participants in employer-sponsored retirement plans where a financial intermediary provides recordkeeping services to plan participants. The classes have different unified management fees as a result of their separate arrangements for shareholder services. In addition, the A, C and R Class shares each are subject to a separate Master Distribution and Individual Shareholder Services Plan (the A Class Plan, C Class Plan and R Class Plan, respectively, and collectively, the plans) described below. The plans have been adopted by the funds' Board of Directors in accordance with Rule 12b-1 adopted by the SEC under the Investment Company Act.

**Rule 12b-1**

Rule 12b-1 permits an investment company to pay expenses associated with the distribution of its shares in accordance with a plan adopted by its Board of Directors and approved by its shareholders. Pursuant to such rule, the Board of Directors of the funds' A, C and R Classes have approved and entered into the A Class Plan, C Class Plan and R Class Plan, respectively. The plans are described below.

------

In adopting the plans, the Board of Directors (including a majority of directors who are not interested persons of the funds, as defined in the Investment Company Act, hereafter referred to as the independent directors) determined that there was a reasonable likelihood that the plans would benefit the funds and the shareholders of the affected class. Some of the anticipated benefits include improved name recognition of the funds generally and growing assets in existing funds, which helps retain and attract investment management talent and provides a better environment for improving fund performance. Pursuant to Rule 12b-1, information about revenues and expenses under the plans is presented to the Board of Directors quarterly. Continuance of the plans must be approved by the Board of Directors, including a majority of the independent directors, annually. The plans may be amended by a vote of the Board of Directors, including a majority of the independent directors, except that the plans may not be amended to materially increase the amount to be spent for distribution without majority approval of the shareholders of the affected class. The plans terminate automatically in the event of an assignment and may be terminated upon a vote of a majority of the independent directors or by vote of a majority of the outstanding voting securities of the affected class.

All fees paid under the plans will be made in accordance with Section 2830 of the Conduct Rules of the Financial Industry Regulatory Authority (FINRA).

**The Share Class Plans**

As described in the prospectuses, the A, C and R Class shares of the funds are made available to participants in employer-sponsored retirement plans and to persons purchasing through broker-dealers, banks, insurance companies and other financial intermediaries that provide various administrative, shareholder and distribution services. The funds' distributor enters into contracts with various banks, broker-dealers, insurance companies and other financial intermediaries, with respect to the sale of the funds' shares and/or the use of the funds' shares in various investment products or in connection with various financial services.

Certain recordkeeping and administrative services that would otherwise be performed by the funds' transfer agent may be performed by a plan sponsor (or its agents) or by a financial intermediary for A, C and R Class investors. In addition to such services, the financial intermediaries provide various individual shareholder and distribution services.

To enable the funds' shares to be made available through such plans and financial intermediaries, and to compensate them for such services, the funds' Board of Directors has adopted the A Class, C Class and R Class Plans. Pursuant to the plans, the following fees are paid and described further below.

***A Class***

The A Class pays the funds' distributor 0.25% annually of the average daily net asset value of the A Class shares. The distributor may use these fees to pay for certain ongoing shareholder and administrative services and for distribution services, including past distribution services. This payment is fixed at 0.25% and is not based on expenses incurred by the distributor.

***C Class***

The C Class pays the funds' distributor 1.00% annually of the average daily net asset value of the funds' C Class shares, 0.25% of which is paid for certain ongoing individual shareholder and administrative services and 0.75% of which is paid for distribution services, including past distribution services. This payment is fixed at 1.00% and is not based on expenses incurred by the distributor.

***R Class***

The R Class pays the funds' distributor 0.50% annually of the average daily net asset value of the R Class shares. The distributor may use these fees to pay for certain ongoing shareholder and administrative services and for distribution services, including past distribution services. This payment is fixed at 0.50% and is not based on expenses incurred by the distributor.

During the fiscal year ended July 31, 2025, the aggregate amount of fees paid under each class plan are indicated in the following table. Because One Choice 2070 Portfolio and One Choice Blend+ 2070 Portfolio are new, they are not included in the table below. **[Table to be updated]**

The distributor then makes these payments to the financial intermediaries (including underwriters and broker-dealers, who may use some of the proceeds to compensate sales personnel) who offer the A, C and R Class shares for the services described below. No portion of these payments is used by the distributor to pay for advertising, printing costs or interest expenses.

Payments may be made for a variety of individual shareholder services, including, but not limited to:

(a)providing individualized and customized investment advisory services, including the consideration of shareholder profiles and specific goals;

(b)creating investment models and asset allocation models for use by shareholders in selecting appropriate funds;

(c)conducting proprietary research about investment choices and the market in general;

(d)periodic rebalancing of shareholder accounts to ensure compliance with the selected asset allocation;

(e)consolidating shareholder accounts in one place;

(f)paying service fees for providing personal, continuing services to investors, as contemplated by the Conduct Rules of FINRA; and

(g)other individual services.

Individual shareholder services do not include those activities and expenses that are primarily intended to result in the sale of additional shares of the funds.

**Valuation of a Fund's Securities**

The net asset value (NAV) of each class of each fund is calculated by adding the value of all portfolio securities and other assets attributable to the class, deducting liabilities, and dividing the result by the number of shares of the class outstanding. Expenses and interest earned on portfolio securities are accrued daily.

All classes of the funds except the A Class are offered at their NAV. The A Class of the funds is offered at its public offering price, which is the NAV plus the appropriate sales charge. This calculation may be expressed as a formula:

Offering Price = NAV/(1 – Sales Charge as a % of Offering Price)

For example, if the NAV of a fund's A Class shares is $5.00, the public offering price would be $5/(1-5.75%) = $5.31.

Each fund's NAV is calculated as of the close of trading on the New York Stock Exchange (NYSE) each day the NYSE is open for business. The NYSE usually closes at 4 p.m. Eastern time. The NYSE typically observes the following holidays: New Year's Day, Martin Luther King Jr. Day, Washington's Birthday, Good Friday, Memorial Day, Juneteenth National Independence Day, Independence Day, Labor Day, Thanksgiving Day and Christmas Day. Although the funds expect the same holidays to be observed in the future, the NYSE may modify its holiday schedule at any time.

With respect to the portion of each fund's assets that are invested in underlying mutual funds, the fund's NAV is calculated based upon the NAVs of such underlying mutual funds. The prospectuses for the underlying funds explain the methods used to value underlying mutual fund shares.

Portfolio securities for which market quotations are readily available are valued at their market price. If the fund invests in ETFs, such ETFs are valued at the last reported official closing price or sale price at the time the NAV is determined.

**Special Requirements for Large Redemptions**

If, during any 90-day period, you redeem fund shares worth more than $250,000 (or 1% of the value of a fund's assets if that amount is less than $250,000), we reserve the right to pay part or all of the redemption proceeds in excess of this amount in readily marketable securities instead of in cash. To the extent practicable, these securities will represent your pro rata share of the fund's securities.

We will value these securities in the same manner as we do in computing the fund's net asset value. We may provide these securities in lieu of cash without prior notice. Also, if payment is made in securities, you may have to pay brokerage or other transaction costs to convert the securities to cash. These securities remain subject to market risk until sold, and you may incur capital gains and/or losses when you sell the securities.

If your redemption would exceed this limit and you would like to avoid being paid in securities, please provide us with an unconditional instruction to redeem at least 15 days prior to the date on which the redemption transaction is to occur. The instruction must specify the dollar amount or number of shares to be redeemed and the date of the transaction. This minimizes the effect of the redemption on a fund and its remaining investors.

**Taxes**

**Federal Income Tax**

Each fund intends to qualify annually as a regulated investment company (RIC) under Subchapter M of the Internal Revenue Code of 1986, as amended (the Code). RICs generally are not subject to federal and state income taxes. To qualify as a RIC a fund must, among other requirements, distribute substantially all of its net investment income and net realized capital gains (if any) to investors each year. If a fund were not eligible to be treated as a RIC, it would be liable for taxes at the fund level on all its income, significantly reducing its distributions to investors and eliminating investors' ability to treat distributions received from the fund in the same manner in which they were realized by the fund. Under certain circumstances, the Code allows funds to cure deficiencies that would otherwise result in the loss of RIC status including by paying a fund-level tax.

To qualify as a RIC, a fund must meet certain requirements of the Code, among which are requirements relating to sources of its income and diversification of its assets. A fund is also required to distribute 90% of its investment company taxable income each year. Additionally, a fund must declare dividends by December 31 of each year equal to at least 98% of ordinary income (as of December 31) and 98.2% of capital gains (as of October 31) to avoid the nondeductible 4% federal excise tax on any undistributed amounts.

If more than 50% of the value of a fund's total assets at the end of its fiscal year consists of securities of foreign corporations or if more than 50% of the value of a fund's assets consists of other RICs at the end of its fiscal quarters (and such other RICs have passed through foreign tax credits to their shareholders), the fund may make an election with the Internal Revenue Service (IRS) with respect to such fiscal year so that fund shareholders may be able to claim a foreign tax credit for foreign taxes paid by the fund or passed through to the fund from other RICs. If such an election is made, the eligible foreign taxes will be treated as income received by you.

------

In order for you to utilize the foreign tax credit, you must have held your shares for 16 days or more during the 31-day period beginning 15 days prior to the ex-dividend date for the mutual fund shares. The mutual fund must meet a similar holding period requirement with respect to securities to which a dividend is attributable. Any foreign taxes withheld on payments made "in lieu of" dividends or interest with respect to loaned securities will not qualify for the pass-through foreign tax credit to shareholders. Any portion of the foreign tax credit that is ineligible will be deducted in computing net investment income.

A fund's investment in underlying mutual funds could affect the amount, timing and character of distributions from the funds, and therefore may increase the amount of taxes payable by shareholders.

As of July 31, 2025, the funds in the table below had the following capital loss carryovers. When a fund has a capital loss carryover, it does not make capital gains distributions until the loss has been offset. The Regulated Investment Company Modernization Act of 2010 allows the funds to carry forward capital losses incurred in future taxable years for an unlimited period. **[Table to be updated]**

If you have not complied with certain provisions of the Internal Revenue Code and Regulations, either American Century Investments or your financial intermediary is required by federal law to withhold and remit to the IRS the applicable federal withholding rate of reportable payments (which may include dividends, capital gains distributions and redemption proceeds). Those regulations require you to certify that the Social Security number or tax identification number you provide is correct and that you are not subject to withholding for previous under-reporting to the IRS. You will be asked to make the appropriate certification on your account application. Payments reported by us to the IRS that omit your Social Security number or tax identification number will subject us to a non-refundable penalty of $50, which will be charged against your account if you fail to provide the certification by the time the report is filed.

If fund shares are purchased through taxable accounts, distributions of either cash or additional shares of net investment income and net short-term capital gains are taxable to you as ordinary income, unless they are designated as qualified dividend income and you meet a minimum required holding period with respect to your shares of a fund, in which case such distributions are taxed at the same rates as long-term capital gains. Qualified dividend income is a dividend received by a fund from the stock of a domestic or qualifying foreign corporation, provided that the fund has held the stock for a required holding period and the stock was not on loan at the time of the dividend. The required holding period for qualified dividend income is met if the underlying shares are held more than 60 days in the 121-day period beginning 60 days prior to the ex-dividend date. Dividends received by the funds on shares of stock of domestic corporations (excluding Real Estate Investment Trusts) may qualify for the 70% dividends-received deduction when distributed to corporate shareholders to the extent that the fund held those shares for more than 45 days.

Distributions from gains on assets held by the funds longer than 12 months are taxable as long-term gains regardless of the length of time you have held your shares in the fund. If you purchase shares in the fund and sell them at a loss within six months, your loss on the sale of those shares will be treated as a long-term capital loss to the extent of any long-term capital gains dividend you received on those shares.

Each fund may use the "equalization method" of accounting to allocate a portion of its earnings and profits to redemption proceeds. Although using this method generally will not affect a fund's total returns, it may reduce the amount that a fund would otherwise distribute to continuing shareholders by reducing the effect of redemptions of fund shares on fund distributions to shareholders.

A redemption of shares of a fund (including a redemption made in an exchange transaction) will be a taxable transaction for federal income tax purposes and you generally will recognize gain or loss in an amount equal to the difference between the basis of the shares and the amount received. If a loss is realized on the redemption of fund shares, the reinvestment in additional fund shares within 30 days before or after the redemption may be subject to the "wash sale" rules of the Code, postponing the recognition of such loss for federal income tax purposes.

A 3.8% Medicare contribution tax is imposed on net investment income, including interest, dividends and capital gains, provided you meet specified income levels.

**State and Local Taxes**

Distributions by the funds also may be subject to state and local taxes, even if all or a substantial part of those distributions are derived from interest on U.S. government obligations which, if you received such interest directly, would be exempt from state income tax.

------

However, most, but not all, states allow this tax exemption to pass through to fund shareholders when a fund pays distributions to its shareholders. You should consult your tax advisor about the tax status of such distributions in your own state.

The information above is only a summary of some of the tax considerations affecting the funds and their U.S. shareholders. No attempt has been made to discuss individual tax consequences. A prospective investor should consult with his or her tax advisors or state or local tax authorities to determine whether the funds are suitable investments.

**Financial Statements**

One Choice 2070 Portfolio and One Choice Blend+ 2070 Portfolio do not have financial statements or financial highlights as they are new. Each of the other funds' financial statements and financial highlights for the fiscal year ended July 31, 2025 have been audited by Deloitte & Touche LLP, independent registered public accounting firm. Their Reports of Independent Registered Public Accounting Firm and the financial statements included in the funds' <u>[Form N-CSR](https://www.sec.gov/ix?doc=/Archives/edgar/data/1293210/000129321024000110/ck0001293210-20240731.htm)</u> for the fiscal year ended July 31, 2025 are incorporated herein by reference.

**Appendix A – Principal Shareholders**

As of October 31, 2025, the following shareholders owned more than 5% of the outstanding shares of a class of a fund. The table shows shares owned of record unless otherwise noted. Because One Choice 2070 Portfolio and One Choice Blend+ 2070 Portfolio are new, they are not included in the table below. **[Table to be updated]**

A shareholder owning beneficially more than 25% of the corporation's outstanding shares may be considered a controlling person. The vote of any such person could have a more significant effect on matters presented at a shareholders' meeting than votes of other shareholders. The funds are unaware of any shareholders, beneficial or of record, who own more than 25% of the voting securities of the corporation. As of [October 31, 2025], the officers and directors of the funds, as a group, owned less than 1% of any class of a fund's outstanding shares.

**Appendix B – Sales Charges and Payments to Dealers** 

**Sales Charges**

The sales charges applicable to the A and C Classes of the funds are described in the prospectuses for those classes in the section titled *Investing Through a Financial Intermediary.* Shares of the A Class are subject to an initial sales charge, which declines as the amount of the purchase increases. Additional information regarding reductions and waivers of the A Class sales charge may be found in the funds' prospectuses.

Shares of the A and C Classes are subject to a contingent deferred sales charge (CDSC) upon redemption of the shares in certain circumstances. The specific charges and when they apply are described in the relevant prospectuses. The CDSC may be waived for certain redemptions by some shareholders, as described in the prospectuses.

An investor may terminate his relationship with an intermediary at any time. If the investor does not establish a relationship with a new intermediary and transfer any accounts to that new intermediary, such accounts may be exchanged to the Investor Class of the fund, if such class is available. The investor will be the shareholder of record of such accounts. In this situation, any applicable CDSCs will be charged when the exchange is made.

The aggregate CDSCs paid to the distributor for the A Class shares in the fiscal year ended July 31, 2025 were: **[Table to be updated]**

|:---|:---|
| One Choice 2035 Portfolio | $12 |
| One Choice 2045 Portfolio | $17 |

**Payments to Dealers**

The funds' distributor expects to pay dealer commissions to the financial intermediaries who sell A and/or C Class shares of the funds at the time of such sales. Payments for A Class shares will be as follows:

---

| | |
|:---|:---|
| *Purchase Amount* | *Dealer Commission as a % of Offering Price* |
| Less than $50,000 | 5.00% |
| $50000 - $99999 | 4.00% |
| $100000 - $249999 | 3.25% |
| $250000 - $499999 | 2.00% |
| $500000 - $999999 | 1.75% |
| $1000000 - $3999999 | 1.00% |
| $4000000 - $9999999 | 0.50% |
| $10,000,000 or more | 0.25% |

---

No dealer commission will be paid on purchases by employer-sponsored retirement plans. For this purpose, employer-sponsored retirement plans do not include SEP IRAs, SIMPLE IRAs or SARSEPs. Payments will equal 1.00% of the purchase price of the C Class shares sold by the intermediary. The distributor will retain the 12b-1 fee paid by the C Class of funds for the first 12 months after the shares are purchased. This fee is intended in part to permit the distributor to recoup a portion of on-going sales commissions to dealers plus financing costs, if any. Beginning with the first day of the 13th month, the distributor will make the C Class distribution and individual shareholder services fee payments described above to the financial intermediaries involved on a quarterly basis. In addition, C Class purchases and A Class purchases greater than $1,000,000 are subject to a CDSC as described in the prospectuses.

From time to time, the distributor may make additional payments to dealers, including but not limited to payment assistance for conferences and seminars, provision of sales or training programs for dealer employees and/or the public (including, in some cases, payment for travel expenses for registered representatives and other dealer employees who participate), advertising and sales campaigns about a fund or funds, and assistance in financing dealer-sponsored events. Other payments may be offered as well, and all

------

such payments will be consistent with applicable law, including the then-current rules of the Financial Industry Regulatory Authority (FINRA). Such payments will not change the price paid by investors for shares of the funds.

------

**Appendix C – Buying and Selling Fund Shares** 

Information about buying, selling, exchanging and, if applicable, converting fund shares is contained in the funds' prospectuses. The prospectuses are available to investors without charge and may be obtained by calling us.

**Employer-Sponsored Retirement Plans**

Certain group employer-sponsored retirement plans that hold a single account for all plan participants with the fund, or that are part of a retirement plan or platform offered by banks, broker-dealers, financial advisors or insurance companies, or serviced by retirement recordkeepers are eligible to purchase Investor, I, A, C, R and R6 Class shares. A and C Class purchases are available at net asset value with no dealer commission paid to the financial professional, and do not incur a CDSC. A, C and R Class shares purchased in employer-sponsored retirement plans are subject to applicable distribution and service (12b-1) fees, which the financial intermediary begins receiving immediately at the time of purchase. American Century does not impose minimum initial investment amount, plan size or participant number requirements by class for employer-sponsored retirement plans; however, financial intermediaries or plan recordkeepers may require plans to meet different requirements.

Examples of employer-sponsored retirement plans include the following:

• 401(a) plans

• pension plans

• profit sharing plans

• 401(k) plans (including plans with a Roth 401(k) feature, SIMPLE 401(k) plans and Solo 401(k) plans)

• money purchase plans

• target benefit plans

• Taft-Hartley multi-employer pension plans

• SERP and "Top Hat" plans

• ERISA trusts

• employee benefit plans and trusts

• employer-sponsored health plans

• 457 plans

• KEOGH or HR(10) plans

• employer-sponsored 403(b) plans (including plans with a Roth 403(b) feature)

• nonqualified deferred compensation plans

• nonqualified excess benefit plans

• nonqualified retirement plans

Traditional and Roth IRAs are not considered employer-sponsored retirement plans, and SIMPLE IRAs, SEP IRAs and SARSEPs are collectively referred to as Business IRAs. Business IRAs that (i) held shares of an A Class fund prior to March 1, 2009 that received sales charge waivers or (ii) held shares of an Advisor Class fund that was renamed A Class on March 1, 2010, may permit additional purchases by new and existing participants in A Class shares without an initial sales charge.

R Class IRA Accounts established prior to August 1, 2006 may make additional purchases.

**Waiver of Minimum Initial Investment Amounts — I Class**

A financial intermediary, upon receiving prior approval from American Century Investments, may waive applicable minimum initial investment amounts per shareholder for I Class shares in the following situations:

• Broker-dealers, banks, trust companies, registered investment advisors and other financial intermediaries may make I Class shares available with no initial investment minimum in fee based advisory programs or accounts where such program or account is traded omnibus by the financial intermediary;

• Qualified Tuition Programs under Section 529 that have entered into an agreement with the distributor; and

• Certain other situations deemed appropriate by American Century Investments.

------

**Appendix D – Proxy Voting Policies**

American Century Investment Management, Inc. (the "Adviser") is the investment manager for a variety of advisory clients, including the American Century family of funds. In such capacity, the Adviser has been delegated the authority to vote proxies with respect to investments held in certain accounts it manages. The following is a statement of the proxy voting policies (the "Policies") that have been adopted by the Adviser. In the exercise of proxy voting authority, which has been delegated to it by particular clients, the Adviser will apply the Policies in accordance with, and subject to, any specific policies that have been adopted by the client and communicated to and accepted by the Adviser in writing.

**1. General Principles**

In providing the service of voting client proxies, the Adviser is guided by general fiduciary principles, must act prudently, solely in the interest of its clients, and must not subordinate client interests to unrelated objectives. Except as otherwise indicated in these Policies, the Adviser will use its best efforts to vote all proxies with respect to investments held in the client accounts it manages. Shares may not be voted if the cost or administrative burden of voting shares of a particular portfolio company in the judgment of the Adviser exceeds the benefit to fund shareholders. The Adviser will attempt to consider all factors of its vote that could affect the value of the investment.

Although in most instances the Adviser will vote proxies consistently across all client accounts, the votes will be based on the best interests of each client. As a result, accounts managed by the Adviser may at times vote differently on the same proposals. Examples of when an account's vote might differ from other accounts managed by the Adviser include, but are not limited to, proxy contests and proposed mergers. In short, the Adviser will vote proxies in the manner that it believes will do the most to maximize shareholder value.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; **1. Non-U.S. Proxies**

The Adviser will generally evaluate non-U.S. proxies in the context of the Policies but will also, where feasible, take into consideration differing laws, regulations, and practices in the relevant foreign market in determining if and how to vote. There may also be circumstances when practicalities and costs involved with non-U.S. investing make it disadvantageous to vote shares. For instance, the Adviser generally does not vote proxies in circumstances where share blocking restrictions apply, when meeting attendance is required in person, or when current share ownership disclosure is required.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; **2. Stewardship and Engagement**

As long-term owners and as part of its stewardship efforts, the Adviser undertakes regular contact with portfolio company management to provide the Adviser an opportunity to gain additional information when voting proxies.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;**3. Proposals Involving Sustainability Matters** 

The Adviser will vote with the expectation of maximizing shareholder value and believes that certain sustainability issues can potentially impact a company's long-term financial performance. On a case-by-case basis, the financial materiality and potential risks or economic impact of the sustainability issues underpinning proxy proposals are considered and it is ultimately each team's portfolio managers that are responsible for making the voting decision.

The portfolio management teams for portfolios that have sustainability considerations in their mandates can place emphasis around those considerations when voting proxies with the objective of enhancing outcomes.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;**4. Exception Voting** 

The Adviser reserves the right to vote contrary to the Policies when, in its opinion, the vote will do the most to maximize the investment objective of the account.

**2. Specific Proxy Matters**

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; **1. Routine Matters**

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; **1. Election of Directors**

1) ***Generally.*** *(i)* The Adviser will generally support the election of directors that results in a board made up of a majority of independent directors. (ii) In general, the Adviser will vote in favor of management's director nominees if they are running unopposed. The Adviser believes that management is in the best position to evaluate the qualifications of directors and the needs and dynamics of a particular board. (iii) When management's nominees are opposed in a proxy contest, the Adviser will evaluate which nominees' publicly announced management policies and goals are most likely to maximize shareholder value, as well as the past performance of the incumbents (iv) The Adviser maintains the ability to vote against any candidate whom it believes is not qualified or if there are specific concerns about the individual, such as allegations of

------

criminal wrongdoing or breach of fiduciary responsibilities. (v) Additional information the Adviser may consider concerning director nominees include, but is not limited to, whether (1) there is an adequate explanation for repeated absences at board meetings, (2) the nominee receives non-board fee compensation, (3) there is a family relationship between the nominee and the company's chief executive officer or controlling shareholder, and/or (4) the nominee has sufficient time and commitment to serve effectively in light of the nominee's service on other public company boards.

2) ***Committee Service.*** The Adviser will withhold votes for non-independent directors who serve on the audit and/or compensation committees of the board.

3) ***Classification of Boards.*** The Adviser believes classified boards represent a form of anti-takeover device, which is generally not in the interests of minority shareholders. Accordingly, the Adviser will generally support proposals that seek to declassify boards. Additionally, the Adviser will oppose efforts to adopt classified board structures.

4) ***Majority Independent Board.*** The Adviser will support proposals calling for a majority of independent directors on a board. The Adviser believes that a majority of independent directors can help to facilitate objective decision making and enhance accountability to shareholders.

5) ***Majority Vote Standard for Director Elections.*** The Adviser will generally vote in favor of proposals calling for directors to be elected by an affirmative majority of the votes cast in a board election, provided that the proposal allows for a plurality voting standard in the case of contested elections. The Adviser may consider voting against such shareholder proposals where a company's board has adopted an alternative measure, such as a director resignation policy, that provides a meaningful alternative to the majority voting standard and appropriately addresses situations where an incumbent director fails to receive the support of the majority of the votes cast in an uncontested election.

6) ***Separate CEO and Chair.*** The Adviser will generally vote against shareholder proposals requesting an independent chair if the board is majority independent. Conversely, if the board is not majority independent, the Adviser will generally vote in favor of management proposals to separate the roles of CEO and chair of the board of directors.

7) ***Withholding Campaigns.*** The Adviser will generally support proposals calling for shareholders to withhold votes for directors where such actions will advance the principles set forth in paragraphs 1(a) through 1(f) above.

8) ***Director Indemnification.*** The Adviser will generally vote in favor of a corporation's proposal to indemnify its officers and directors in accordance with applicable state law. Indemnification arrangements are often necessary to attract and retain qualified directors.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;**2.Ratification of Selection of Auditors**

The Adviser will generally rely on the judgment of the portfolio company's audit committee in selecting the independent auditors who will provide the best service to the company. The Adviser believes that independence of the auditors is paramount and will vote against auditors whose independence appears to be impaired. The Adviser will generally vote against proposed auditors in circumstances where the auditor has or may have a potential conflict of interest, including where: (a) an auditor has a financial interest in or association with the company, and is therefore not independent; (b) non-audit fees are excessive compared to audit fees (c) the audit firm's tenure is excessively long; or (d) there is reason to believe that the independent auditor has previously rendered an opinion to the company that is either inaccurate or not indicative of the company's financial position.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; **2. Compensation Matters**

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; **1. Executive and Director Compensation**

1) ***Advisory Vote on Compensation.*** The Adviser believes there are several effective ways to convey concerns about compensation including voting against the advisory vote on executive compensation (say-on-pay proposals), voting against specific incentive plans or amendments to incentive plans it deems excessive or withholding votes from compensation committee members. The Adviser will consider and vote on a case-by-case basis on say-on-pay proposals and will generally support management proposals unless there are inadequate risk-mitigation features or other specific concerns exist, including if the Adviser concludes that executive compensation is (i) misaligned with shareholder interests, (ii) unreasonable in amount, or (iii) not in the aggregate meaningfully tied to the company's performance.

------

2) ***Frequency of Advisory Votes on Compensation.*** The Adviser generally supports the triennial option for the frequency of say-on-pay proposals but will consider management recommendations for an alternative approach.

3) ***Clawback of Incentive Compensation.*** The Adviser expects portfolio companies to structure executive compensation plans in a manner that does not encourage excessive risk-taking or insulate management from the consequences of failures of risk management and oversight. The Adviser generally supports properly-structured clawback provisions in executive compensation plans as a way to mitigate the potential for excessive risk taking. In evaluating compensation clawback proposals, the Adviser will consider whether the company has a history of financial restatements, material financial problems, and any other factors deemed relevant.

*4)* ***Directors' Stock Options Plans.*** The Adviser believes that stock options are an appropriate form of compensation for directors, and the Adviser will generally vote for director stock option plans that are reasonable and do not result in excessive shareholder dilution. Analysis of such proposals will be made on a case-by-case basis and will take into account total board compensation and the company's total exposure to stock option plan dilution.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;**2.Equity Based Compensation Plans**

The Adviser believes that equity-based compensation plans are economically significant issues upon which shareholders are entitled to vote. The Adviser recognizes that equity-based compensation plans can be useful in attracting and retaining desirable employees. The cost associated with such plans must be measured if plans are to be used appropriately to maximize shareholder value. The Adviser may conduct an analysis of stock option, stock bonus or similar plans or material amendments thereto, including replenishing a plan with additional shares.

Features that may result in the Adviser voting against the initial adoption of a plan or subsequent amendment to replenish the plan with additional shares include whether the plan:

1) Provides for immediate vesting of all stock options in the event of a change of control of the company without reasonable safeguards against abuse (see "Anti-Takeover Proposals" below);

2) Resets outstanding stock options at a lower strike price, unless accompanied by a corresponding and proportionate reduction in the number of shares designated. The Adviser will generally oppose adoption of stock option plans that explicitly or historically permit repricing of stock options, regardless of the number of shares reserved for issuance, since their effect is impossible to evaluate;

3) Establishes restriction periods shorter than three years for restricted stock grants;

4) Does not reasonably associate awards to performance of the company (especially as it relates to the selection of appropriate vesting metrics, which ideally should contain both absolute and relative measures); or

5) Is excessively dilutive to the company. Factors that will be considered in the determination include the company's overall market capitalization, the performance of the company relative to its peers, and the maturity of the company and its industry; for example, technology companies often use options broadly throughout its employee base, which may justify somewhat greater dilution.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; **3. Non-Stock Incentive Plans**

Management may propose a variety of non-stock, cash-based incentive or bonus plans to stimulate employee performance. In general, the cash or other corporate assets required for most incentive plans is not material, and the Adviser will vote in favor of such proposals. Case-by-case determinations will be made of the appropriateness of the amount of shareholder value transferred by proposed plans.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; **3. Shareholder Rights**

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; **1. One Share, One Vote.** The Adviser generally supports proposals to equalize the voting rights of shareholders, including the elimination of special or super voting share classes and the establishment of single-class voting structures.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; **2. Right to Call Special Shareholder Meetings.** The corporation statutes of many states allow minority shareholders at a certain threshold level of ownership to call a special meeting of shareholders. This right can be eliminated (or the threshold increased) by amendment to the company's charter documents. The Adviser believes that the right to call a special shareholder meeting is significant for minority shareholders; the elimination of such right will be viewed as an anti-takeover measure and the Adviser will generally vote against proposals attempting to eliminate this right and for proposals attempting to restore it.

------

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; **3. Right to Act by Written Consent.** The Adviser will generally vote for proposals to permit shareholders to act by written consent if the company does not currently permit shareholders to call for a special meeting or to act by written consent. The Adviser will generally vote against proposals on written consent if the company permits shareholders the right to call for a special meeting.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; **4. Proxy Access.** The Adviser believes that the ability of qualifying shareholders to nominate a certain number of directors on the company's proxy statement may have corporate governance benefits. Accordingly, the Adviser will generally vote in favor of proposals to adopt proxy access rules offering a balanced set of limitations. When considering such proposals, the factors taken into account will include the following: (i) the ownership percentages and holding periods proposed; (ii) the maximum proportion of directors that shareholders may nominate each year; and (iii) any other material restrictions included in the proposal.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; **4. Anti-Takeover Proposals**

In general, the Adviser will vote against any proposal, whether made by management or shareholders, which the Adviser believes would materially discourage a potential acquisition or takeover. In most cases an acquisition or takeover of a particular company will increase share value. The adoption of anti-takeover measures may prevent or frustrate a bid from being made, may prevent consummation of the acquisition, and may have a negative effect on share price when no acquisition proposal is pending. In particular circumstances, the Adviser may vote in favor of some forms of control protective measures if they are responsive to a particular circumstance, are narrowly focused and have a sunset provision reasonably tied to the circumstances.

The items below discuss specific anti-takeover proposals.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; **1. Staggered Board**

If a company has a "staggered board," its directors are elected for terms of more than one year and only a segment of the board stands for election in any year. Therefore, a potential acquiror cannot replace the entire board in one year even if it controls a majority of the votes. Although staggered boards may provide some degree of continuity and stability of leadership and direction to the board of directors, the Adviser believes that staggered boards are primarily an anti-takeover device and will vote against establishing them and for eliminating them. However, the Adviser does not necessarily vote against the re-election of directors serving on staggered boards.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; **2. Cumulative Voting**

Cumulative voting gives minority shareholders a stronger voice in the company and a greater chance for representation especially when a company maintains a staggered or classified board.

Accordingly, if a company has a staggered board, the Adviser will: a) vote in favor of any proposal to adopt cumulative voting, and b) vote against any proposal to eliminate cumulative voting that is already in place.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;**3."Blank Check" Preferred Stock**

Blank check preferred stock gives the board of directors the ability to issue preferred stock, without further shareholder approval, with such rights, preferences, privileges and restrictions as may be set by the board. In response to a hostile takeover attempt, the board could issue such stock to a friendly party or "white knight" or could establish conversion rights or other rights in the preferred stock which would dilute the common stock and make an acquisition impossible or less attractive. The argument in favor of blank check preferred stock is that it gives the board flexibility in pursuing financing, acquisitions or other proper corporate purposes without incurring the time or expense of a shareholder vote. Generally, the Adviser will vote against blank check preferred stock. However, the Adviser may vote in favor of blank check preferred stock if the proxy statement discloses that such stock is limited to use for a specific, proper corporate objective such as a financing instrument.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; **4. Elimination of Preemptive Rights**

When a company grants preemptive rights, existing shareholders are given an opportunity to maintain their proportional ownership when new shares are issued. A proposal to eliminate preemptive rights is a request from management to revoke that right.

While preemptive rights will protect the shareholder from having its equity diluted, it may also decrease a company's ability to raise capital through stock offerings or use stock for acquisitions or other proper corporate purposes. Preemptive rights may therefore result in a lower market value for the company's stock. In the long term, shareholders could be adversely affected by preemptive rights. The Adviser generally votes against proposals to grant preemptive rights and for proposals to eliminate preemptive rights.

------

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; **5. Non-targeted Share Repurchase**

A non-targeted share repurchase is generally used by company management to prevent the value of stock held by existing shareholders from deteriorating. A non-targeted share repurchase may reflect management's belief in the favorable business prospects of the company. The Adviser finds no disadvantageous effects of a non-targeted share repurchase and will generally vote for the approval of a non-targeted share repurchase subject to analysis of the company's financial condition.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; **6. Increase in Authorized Common Stock**

The issuance of new common stock can also be viewed as an anti-takeover measure, although its effect on shareholder value would appear to be less significant than the adoption of blank check preferred stock. The Adviser will evaluate the amount of the proposed increase and the purpose or purposes for which the increase is sought. If the increase is not excessive and is sought for proper corporate purposes, the Adviser will generally vote to approve the increase. Proper corporate purposes might include, for example, the creation of additional stock to accommodate a stock split or stock dividend, additional stock required for a proposed acquisition, or additional stock required to be reserved upon exercise of employee stock option plans or employee stock purchase plans. Generally, the Adviser will vote in favor of an increase in authorized common stock of up to 100% outstanding and otherwise reserved for all legitimate corporate purposes; increases in excess of 100% are evaluated on a case-by-case basis and will be voted affirmatively if management has provided sound justification for the increase.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; **7. "Supermajority" Voting Provisions**

A "supermajority" voting provision is a provision placed in a company's charter documents which would require approval by the vote of greater than a simple majority (generally ranging from 66% to 90%) of shareholder votes to approve any type of acquisition of the company.

The supermajority provision makes an acquisition more time-consuming and expensive for the acquiror. Accordingly, the Adviser will generally vote against the introduction of supermajority provisions and in favor of their removal.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; **8. "Fair Price" Amendments**

Fair price amendments are another type of charter amendment that would require an offeror to pay a "fair" and uniform price to all shareholders in an acquisition. In general, fair price amendments are designed to protect shareholders from coercive, two-tier tender offers in which some shareholders may be merged out on disadvantageous terms. Fair price amendments also have an anti-takeover impact, although their adoption is generally believed to have less of a negative effect on stock price than other anti-takeover measures. The Adviser will carefully examine all fair price proposals. In general, the Adviser will vote against fair price proposals unless the Adviser concludes that it is likely that the share price will not be negatively affected, and the proposal will not discourage acquisition proposals.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; **9. Poison Pills or Shareholder Rights Plans**

Some companies have retained some version of a poison pill plan (also known as a shareholder rights plan). Poison pill plans generally provide for the issuance of additional equity securities or rights to purchase equity securities upon the occurrence of certain events the company board deems hostile, such as the acquisition of a large block of stock.

The basic argument against poison pills is that they depress share value, discourage offers for the company and serve to "entrench" management. The basic argument in favor of poison pills is that they give management more time and leverage to deal with a takeover bid and, as a result, shareholders may receive a better price. The Adviser believes that the potential benefits of a poison pill plan are outweighed by the potential detriments. The Adviser will generally vote against all forms of poison pills.

The Adviser will, however, consider on a case-by-case basis poison pills that are very limited in time and preclusive effect. The Adviser will generally vote in favor of such a poison pill if it is linked to a business strategy that will – in the Adviser's view – likely result in greater value for shareholders, if the term is less than three years, and if shareholder approval is required to reinstate the expired plan or adopt a new plan at the end of this term.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; **10. Change in Control Agreements**

Change in control (golden parachute) agreements provide substantial compensation to executives who are terminated as a result of a takeover or change in control of their company. The existence of such plans in reasonable amounts probably has only a slight anti-takeover effect. In voting, the Adviser will evaluate the specifics of the plan presented. Features that may result in the Adviser voting against the adoption or

------

extension of such an agreement include the following: (a) single-trigger or modified-single-trigger cash severance; (b) single-trigger acceleration of unvested equity awards; (c) excessive cash severance (greater than 3X base salary and bonus), especially when triggering adverse tax consequences for the recipient, the company, or both; (d) excise tax gross-ups triggered and payable (as opposed to a provision that provides excise tax gross-ups); (e) excessive change in control payments (on an absolute basis or as a percentage of transaction equity value; (f) recent amendments that incorporate any problematic features (such as those above) or recent actions (such as extraordinary equity grants) that may make packages so attractive as to influence merger agreements that may not be in the best interests of shareholders; or (g) the company's assertion that a proposed transaction is conditioned on shareholder approval of the change in control advisory vote.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; **11. Reincorporation**

Reincorporation in a new state is often proposed as one part of a package of anti-takeover measures. Several states provide some type of legislation that greatly discourages takeovers. The Adviser will examine reincorporation proposals on a case-by-case basis.

Generally, if the Adviser believes that the reincorporation will result in greater protection from takeovers, the reincorporation proposal will be opposed. The Adviser will also generally oppose reincorporation proposals involving jurisdictions that specify that directors can recognize non-shareholder interests over those of shareholders. When reincorporation is proposed for a legitimate business purpose and without the negative effects identified above, the Adviser will generally vote affirmatively.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; **12. Confidential Voting**

Companies that have not previously adopted a "confidential voting" policy allow management to view the results of shareholder votes. This gives management the opportunity to contact those shareholders voting against management in an effort to change their votes.

Proponents of secret ballots argue that confidential voting enables shareholders to vote on all issues on the basis of merit without pressure from management to influence their decision. Opponents argue that confidential voting is more expensive and unnecessary; also, holding shares in a nominee name maintains shareholders' confidentiality. The Adviser believes that the only way to insure anonymity of votes is through confidential voting, and that the benefits of confidential voting outweigh the incremental additional cost of administering a confidential voting system. Therefore, the Adviser will generally vote in favor of any proposal to adopt confidential voting.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; **13. Opting In or Out of State Takeover Laws**

State takeover laws typically are designed to make it more difficult to acquire a corporation organized in that state. The Adviser believes that the decision of whether or not to accept or reject offers of merger or acquisition should be made by the shareholders, without unreasonably restrictive state laws that may impose ownership thresholds or waiting periods on potential acquirors. Therefore, the Adviser will generally vote in favor of opting out of restrictive state takeover laws.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; **5. Transaction-Related Proposals**

The Adviser will review transaction related proposals, such as mergers, acquisitions, and corporate reorganizations, on a case-by-case basis, taking into consideration the impact of the transaction on each client account. In some instances, such as the approval of a proposed merger, a transaction may have a differential impact on client accounts depending on the securities held in each account. For example, whether a merger is in the best interest of a client account may be influenced by whether an account holds, and in what proportion, the stock of both the acquirer and the acquiror. In these circumstances, the Adviser may determine that it is in the best interests of the accounts to vote the accounts' shares differently on proposals related to the same transaction.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; **6. Other Matters**

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;**1. Shareholder-sponsored proposals.** Proposals introduced by shareholders will be evaluated for linkage between the proposal, its economic impact, and its potential to maximize long-term shareholder value. Where the economic impact of a proposal is unclear, the Adviser will generally rely on management's assessment of the proposal if the Adviser believes the assessment is reasonable.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; ***2. Anti-Greenmail Shareholder Proposals.*** "Anti-greenmail" proposals generally limit the right of a corporation, without a shareholder vote, to pay a premium or buy out a 5% or greater shareholder. Management often argues that they should not be restricted from negotiating a deal to buy out a significant shareholder at a premium if they believe it is in the best interest of the company. Institutional shareholders generally believe that all shareholders should be able to vote on such a significant use of corporate assets.

------

The Adviser believes that any repurchase by the company at a premium price of a large block of stock should be subject to a shareholder vote. Accordingly, it will generally vote in favor of anti-greenmail proposals.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;***3. Director Tenure.*** Director Tenure proposals ask that age and term restrictions be placed on the board of directors. The Adviser believes that these types of blanket restrictions are not necessarily in the best interests of shareholders and therefore will consider and assess such measures as appropriate.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; ***4. Director Share Ownership.*** The Adviser will generally vote against shareholder proposals that would require directors to hold a minimum number of the company's shares to serve on the board of directors, in the belief that such ownership should be at the discretion of board members.

**3. Securities on Loan**

The Adviser shall use commercially reasonable efforts to monitor for material proxy votes with respect to loaned securities. In the event the Adviser has timely knowledge of a material vote, the Adviser will attempt to recall the loaned securities and submit a proxy in accordance with these proxy guidelines. Efforts to recall loaned securities may not be successful and there can be no guarantee that a valid proxy will be submitted in all cases.

**4. Use of Proxy Advisory Services**

The Adviser may retain proxy advisory firms to provide services in connection with voting proxies, including, without limitation, to provide information on shareholder meeting dates and proxy materials, translate proxy materials printed in a foreign language, provide research on proxy proposals and voting recommendations in accordance with the Policies, provide systems to assist with casting the proxy votes, and provide reports and assist with preparation of filings concerning the proxies voted.

Prior to the selection of a proxy advisory firm and periodically thereafter, the Adviser will consider whether the proxy advisory firm has the capacity and competency to adequately analyze proxy issues and the ability to make recommendations based on material, accurate information in an impartial manner. Such considerations may include some or all of the following (i) periodic sampling of votes cast through the firm's systems to determine that votes are in accordance with the Adviser's Policies and its clients' best interests, (ii) onsite visits to the proxy advisory firm's office and/or discussions with the firm to determine whether the firm continues to have the resources (e.g. staffing, personnel, technology, etc.) capacity and competency to carry out its obligations to the Adviser, (iii) a review of the firm's policies and procedures, with a focus on those relating to identifying and addressing conflicts of interest and monitoring that current and accurate information is used in creating recommendations, (iv) requesting that the firm notify the Adviser if there is a change in the firm's material policies and procedures, particularly with respect to conflicts, or material business practices (e.g., entering or exiting new lines of business), and reviewing any such change, and (v) in case of an error made by the firm, discussing the error with the firm and determining whether appropriate corrective and preventative action is being taken. In the event the Adviser discovers an error in the research or voting recommendations provided by the firm, it will take reasonable steps to investigate the error and seek to determine whether the firm is taking reasonable steps to reduce similar errors in the future.

While the Adviser takes into account information from many different sources, including independent proxy advisory services, the decision on how to vote proxies will be made in accordance with these Policies.

**5. Monitoring Potential Conflicts of Interest**

The Adviser is responsible for monitoring and resolving possible conflicts between the interests of the Adviser and those of its clients with respect to proxy voting. The Adviser has adopted safeguards to address the potential that our proxy voting could be influenced by interests other than those of our fund shareholders and clients. Since our Policies are predetermined by the Adviser, application of the Policies to vote clients' proxies should in most instances adequately address any possible conflicts of interest. However, for proxy votes inconsistent with the Policies, the Adviser's Proxy Voting Committee reviews all such proxy votes to determine whether the portfolio manager's voting rationale appears reasonable and is consistent with the general principles of the Policies. The Proxy Voting Committee also assesses whether certain business or other significant relationships between the Adviser and a company could have influenced an inconsistent vote on that company's proxy. Issues raising possible conflicts of interest are referred to the Proxy Voting Committee for immediate resolution prior to the time the Adviser casts its vote. With respect to personal conflicts of interest, the Adviser's Code of Ethics requires all employees to avoid placing themselves in a compromising position where their interests may conflict with those of our clients and restricts their ability to engage in certain outside business activities. Portfolio managers and other personnel involved with proxy voting with a personal conflict of interest regarding a particular proxy vote must recuse themselves and not participate in the voting decisions with respect to that proxy.

In addition, to avoid any potential conflict of interest that may arise when the Adviser votes proxies of a fund, portfolio, or other account ("Adviser-Voted Portfolio") that owns shares of an American Century fund, the Adviser will "echo vote" such shares, if possible. Echo voting means the Adviser will vote the shares in the same proportion as the vote of all the other

------

holders of the fund's shares. So, for example, if shareholders of a fund cast 80% of their votes in favor of a proposal and 20% against the proposal, any Adviser-Voted Portfolio that owns shares of such fund will cast 80% of its shares in favor of the proposal and 20% against. When this is not possible, shares will be voted in consultation with the Adviser-Voted Portfolio client or an appropriate fiduciary responsible for the client (e.g., a committee of the independent directors of a fund or the trustee of a retirement plan).

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

The Policies will be examined from time to time and may be amended by the Adviser. With respect to matters that do not fit in the categories stated above, the Adviser will exercise its best judgment as a fiduciary to vote in the manner that will most enhance shareholder value.

Case-by-case determinations will be made by the Adviser. Electronic records will be kept of all votes made.
