Fund Summary – One Choice Portfolio: Very Conservative
Investment Objective
The fund seeks the highest total return consistent with its asset mix.
Fees and Expenses
The following table describes the fees and expenses you may pay if you buy, hold, and sell shares of the fund. You may pay other fees, such as brokerage commissions and other fees to financial intermediaries, which are not reflected in the tables and examples below.
Shareholder Fees (fees paid directly from your investment)
  Investor Class R Class
Maximum Annual Account Maintenance Fee
(waived if eligible investments total at least $10,000)
$25 None
Annual Fund Operating Expenses (expenses that you pay each year as a percentage of the value of your investment)
  Investor Class R Class
Management Fee None None
Distribution and Service (12b-1) Fees None 0.50%
Other Expenses 0.00% 0.00%
Acquired Fund Fees and Expenses 0.69% 0.69%
Total Annual Fund Operating Expenses 0.69% 1.19%
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 $71 $221 $385 $859
R Class $122 $378 $655 $1,443
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 9% of the average value of its portfolio.
Principal Investment Strategies
One Choice Portfolio: Very Conservative is a “fund of funds,” meaning that it seeks to achieve its objective by investing in other American Century Investments mutual funds (the underlying funds) that represent a variety of asset classes and investment styles. The fund’s asset allocation strategy emphasizes investments in fixed-income securities and short-term investments, but maintains a portion of the fund’s assets in equity securities.
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 over the long term. The table also shows the neutral weightings of each underlying fund currently being used within the various asset classes. This information is as of the date of this prospectus.


2


Equity Securities (Stock Funds) 25.00  % Fixed-Income Securities (Bond Funds) 62.00  %
Growth Fund 2.25  % Diversified Bond Fund 18.00  %
Disciplined Growth Fund 1.50  % High Income Fund 2.00  %
Sustainable Equity Fund 6.50  % Inflation-Adjusted Bond Fund 11.00  %
Focused Large Cap Value Fund 6.25  % Short Duration Inflation Protection Bond Fund 13.00  %
Heritage Fund 2.25  % International Bond Fund 7.00  %
Mid Cap Value Fund 3.25  % Global Bond Fund 9.00  %
Small Cap Growth Fund 0.50  % Emerging Markets Debt Fund 2.00  %
Small Cap Value Fund 0.50  %
Real Estate Fund 2.00  % Short-Term Investments (Short-Term Funds) 13.00  %
Short Duration Fund 13.00  %
The managers regularly review the fund and may make changes to the fund’s asset class allocations that deviate from the neutral mix to emphasize investments that they believe will provide the most favorable outlook for achieving the fund’s objective. The fund also may deviate from the neutral mix due to differences in asset class performance or prevailing market conditions. The following table shows the operating ranges within which the fund’s asset class allocations generally will vary over short-term periods.
  Equity Securities
(Stock Funds)
Fixed-Income Securities
(Bond Funds)

Operating Ranges 20-30% 52-72% 3-25%

Principal Risks
Allocation Risk – The fund’s ability to achieve its investment objective depends in part on the managers’ skill in determining the funds’ asset class allocations and in selecting and weighting the underlying funds. The managers’ evaluations and assumptions regarding asset classes and 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. Shareholders of the fund will also indirectly bear their pro rata share of the expenses of such underlying funds. The fund’s investment in other American Century Investments funds may create a conflict of interest for the fund’s advisor.
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.
Public Health Emergency Risk – A pandemic, caused by the infectious respiratory illness COVID-19, has caused market disruption and other economic impacts. Markets experienced volatility, reduced liquidity, and increased trading costs. The pandemic may continue to impact the fund and its underlying funds.
“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.
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 the inability or perceived inability 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.
3


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.
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 a broad measure of market performance. 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). 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. 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.
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. 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.

Fund Summary – One Choice Portfolio: Conservative
Investment Objective
The fund seeks the highest total return consistent with its asset mix.
Fees and Expenses 
The following table describes the fees and expenses you may pay if you buy, hold, and sell shares of the fund. You may pay other fees, such as brokerage commissions and other fees to financial intermediaries, which are not reflected in the tables and examples below.
Shareholder Fees (fees paid directly from your investment)
  Investor Class R Class
Maximum Annual Account Maintenance Fee
(waived if eligible investments total at least $10,000)
$25 None
Annual Fund Operating Expenses (expenses that you pay each year as a percentage of the value of your investment)
  Investor Class R Class
Management Fee None None

Other Expenses 0.00% 0.00%
Acquired Fund Fees and Expenses 0.79% 0.79%
Total Annual Fund Operating Expenses 0.79% 1.29%
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 $81 $253 $439 $978
R Class $132 $410 $708 $1,556
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 10% of the average value of its portfolio.
Principal Investment Strategies
One Choice Portfolio: Conservative is a “fund of funds,” meaning that it seeks to achieve its objective by investing in other American Century Investments mutual funds (the underlying funds) that represent a variety of asset classes and investment styles.

The managers regularly review the fund and may make changes to the fund’s asset class allocations that deviate from the neutral mix to emphasize investments that they believe will provide the most favorable outlook for achieving the fund’s objective.

Principal Risks 
Allocation Risk – The fund’s ability to achieve its investment objective depends in part on the managers’ skill in determining the funds’ asset class allocations and in selecting and weighting the underlying funds. The managers’ evaluations and assumptions regarding asset classes and 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. Shareholders of the fund will also indirectly bear their pro rata share of the expenses of such underlying funds. The fund’s investment in other American Century Investments funds may create a conflict of interest for the fund’s advisor.
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.
Public Health Emergency Risk – A pandemic, caused by the infectious respiratory illness COVID-19, has caused market disruption and other economic impacts. Markets experienced volatility, reduced liquidity, and increased trading costs. The pandemic may continue to impact the fund and its underlying funds.
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.
“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.
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.
7


Credit Risk – The value of an underlying fund’s fixed-income securities will be affected adversely by the inability or perceived inability 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.
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.
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.

Investment Objective 
The fund seeks the highest total return consistent with its asset mix. 
Fees and Expenses
The following table describes the fees and expenses you may pay if you buy, hold, and sell shares of the fund. You may pay other fees, such as brokerage commissions and other fees to financial intermediaries, which are not reflected in the tables and examples below.
Shareholder Fees (fees paid directly from your investment)
  Investor Class R Class
Maximum Annual Account Maintenance Fee
(waived if eligible investments total at least $10,000)
$25 None
Annual Fund Operating Expenses (expenses that you pay each year as a percentage of the value of your investment)

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 $89 $278 $483 $1,073
R Class $140 $435 $751 $1,645
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 11% of the average value of its portfolio.
Principal Investment Strategies
One Choice Portfolio: Moderate is a “fund of funds,” meaning that it seeks to achieve its objective by investing in other American Century Investments mutual funds (the underlying funds) that represent a variety of asset classes and investment styles. The fund’s asset allocation strategy emphasizes investments in equity securities, but maintains a sizeable portion of the fund’s assets in fixed-income securities and short-term investments.

The managers regularly review the fund and may make changes to the fund’s asset class allocations that deviate from the neutral mix to emphasize investments that they believe will provide the most favorable outlook for achieving the fund’s objective. The fund also may deviate from the neutral mix due to differences in asset class performance or prevailing market conditions. The following table shows the operating ranges within which the fund’s asset class allocations generally will vary over short-term periods.

Principal Risks
Allocation Risk – The fund’s ability to achieve its investment objective depends in part on the managers’ skill in determining the funds’ asset class allocations and in selecting and weighting the underlying funds. The managers’ evaluations and assumptions regarding asset classes and 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. Shareholders of the fund will also indirectly bear their pro rata share of the expenses of such underlying funds. The fund’s investment in other American Century Investments funds may create a conflict of interest for the fund’s advisor.
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.
Public Health Emergency Risk – A pandemic, caused by the infectious respiratory illness COVID-19, has caused market disruption and other economic impacts. Markets experienced volatility, reduced liquidity, and increased trading costs. The pandemic may continue to impact the fund and its underlying funds.
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.
“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.
11


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 the inability or perceived inability 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.
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.
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.

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. 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.

Fund Summary – One Choice Portfolio: Aggressive
Investment Objective
The fund seeks the highest total return consistent with its asset mix.
Fees and Expenses
The following table describes the fees and expenses you may pay if you buy, hold, and sell shares of the fund. You may pay other fees, such as brokerage commissions and other fees to financial intermediaries, which are not reflected in the tables and examples below.
Shareholder Fees (fees paid directly from your investment)
  Investor Class R Class
Maximum Annual Account Maintenance Fee
(waived if eligible investments total at least $10,000)
$25 None
Annual Fund Operating Expenses (expenses that you pay each year as a percentage of the value of your investment)
  Investor Class R Class
Management Fee None None
Distribution and Service (12b-1) Fees None 0.50%
Other Expenses 0.00% 0.00%
Acquired Fund Fees and Expenses 0.93% 0.93%
Total Annual Fund Operating Expenses 0.93% 1.43%
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 $95 $297 $515 $1,143
R Class $146 $453 $782 $1,712
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 11% of the average value of its portfolio.
Principal Investment Strategies
One Choice Portfolio: Aggressive is a “fund of funds,” meaning that it seeks to achieve its objective by investing in other American Century Investments mutual funds (the underlying funds) that represent a variety of asset classes and investment styles. The fund’s asset allocation strategy emphasizes investments in equity securities, but maintains a portion of the fund’s assets in fixed-income securities and short-term investments.
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 over the long term. The table also shows the neutral weightings of each underlying fund currently being used within the various asset classes. This information is as of the date of this prospectus.

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 (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 11% of the average value of its portfolio.

Principal Risks
Allocation Risk – The fund’s ability to achieve its investment objective depends in part on the managers’ skill in determining the funds’ asset class allocations and in selecting and weighting the underlying funds. The managers’ evaluations and assumptions regarding asset classes and 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. Shareholders of the fund will also indirectly bear their pro rata share of the expenses of such underlying funds. The fund’s investment in other American Century Investments funds may create a conflict of interest for the fund’s advisor.
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.
Public Health Emergency Risk – A pandemic, caused by the infectious respiratory illness COVID-19, has caused market disruption and other economic impacts. Markets experienced volatility, reduced liquidity, and increased trading costs. The pandemic may continue to impact the fund and its underlying funds.
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.
“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.
20


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.
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.
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.

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. 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.

The managers regularly review each fund and may modify the underlying funds’ neutral weightings or substitute other underlying funds to emphasize investments that they believe will provide the most favorable outlook for achieving a fund’s objective. 
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 in 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) 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.
Although the funds generally will remain exposed to each of the investment disciplines and categories described above, a particular investment discipline or category may be emphasized when, in the managers’ opinion, such investment discipline or category is undervalued relative to the other disciplines or categories.
A brief description of each of the underlying funds follows. Additional details are available in the statement of additional information and the underlying funds’ prospectuses.

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 asset class allocations and in selecting and weighting the underlying funds. 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 also 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 names of the funds are intended to reflect the relative short-term price volatility risk among the funds and are not an indication of the advisor’s assessment of the riskiness of the funds as compared to other mutual funds, including other mutual funds within the American Century Investments family of funds.
Shareholders of the fund will also indirectly bear their pro rata share of the expenses charged by the underlying funds. Such expenses may increase or decrease due to changes in the fund’s asset mix or due to changes in the underlying fund’s expenses.
Although the fund’s advisor does not receive a management fee for managing the fund, the advisor receives fees for managing the underlying funds. In addition, 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.

25


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’ assessments of a company’s prospects for earnings 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 markets.
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. A period of rising interest rates may negatively affect the fund’s 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.
The value of an underlying fund’s fixed-income securities also will be affected by the continued ability 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.
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.
A pandemic, caused by the infectious respiratory illness COVID-19, caused travel restrictions, disruption of healthcare systems, prolonged quarantines, cancellations, supply chain interruptions, lower consumer demand, layoffs, credit downgrades, and defaults among other economic impacts. Certain markets experienced temporary closures, extreme volatility, losses, reduced liquidity and increased trading costs. The pandemic may continue to impact the fund and its underlying funds.
These funds are intended for investors who seek to diversify their assets among various classes of investments, such as stocks, bonds and short-term investments, and who are willing to accept the risks associated with the funds’ asset allocation 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 or have tax consequences. To the extent that a large shareholder (including a 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.

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. Although the advisor does not receive a separate fee for managing the funds, the advisor does receive a management fee for managing the underlying funds. See the underlying funds’ prospectuses for specific fees. 
A discussion regarding the basis for the Board of Directors’ approval of the funds’ investment advisory agreement with the advisor is available in the funds’ annual report to shareholders dated July 31, 2022. 
The Fund Management Team
The advisor uses a team of portfolio managers and analysts to manage the funds in consultation with the firm’s Asset Allocation Committee, which is responsible for reviewing portfolio performance and approving strategic investment policy decisions for the funds. The following portfolio managers are jointly and primarily responsible for coordinating the funds’ activities, including determining appropriate asset allocations, reviewing overall fund compositions for compliance with stated investment objectives and strategies, and monitoring cash flows. The team meets as necessary to review the funds’ allocations.

Investing Through a Financial Intermediary
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.
Financial intermediaries include banks, broker-dealers, insurance companies, plan sponsors and financial professionals.
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 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.
If you do business with us through a financial intermediary or an employer-sponsored retirement plan, your ability to purchase, exchange, redeem and transfer shares will be affected by the policies of that entity. 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 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 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 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. 
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 and R 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. 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.
31


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. 

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
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.
Broker-dealer sponsored wrap program accounts and/or fee-based advisory accounts No minimum
Coverdell Education Savings Account and IRAs
$1,0001,2
Employer-sponsored retirement plans No minimum
1     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.
2     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. 
Redemptions
Your redemption proceeds will be calculated using the net asset value (NAV) next determined after we receive your transaction request in good order.
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 statement of additional information. 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
33


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 you may incur tax liability as a result of the redemption.
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
Frequent trading and other abusive trading practices may disrupt portfolio management strategies and harm fund performance. Additionally, because the funds invest in other American Century Investments mutual funds, frequent trading and other abusive trading activity in the funds may disrupt the underlying funds’ portfolio management strategies and harm their performance. If the cumulative amount of frequent trading activity is significant relative to an underlying fund’s net assets, the underlying fund may incur trading costs that are higher than necessary as securities are first purchased then quickly sold to meet the redemption request. In such case, each fund, as a shareholder of the underlying funds, would indirectly bear its pro rata share of the additional expenses incurred by the underlying funds. Accordingly, the funds’ performance could be negatively impacted by the increased trading costs created by frequent trading if the additional trading costs are significant.
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.
34


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.

35


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.
36


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.
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 a fund, as well as capital gains realized by a 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.
Distributions of substantially all of their income are paid quarterly for One Choice Portfolio: Very Conservative, One Choice Portfolio: Conservative and One Choice Portfolio: Moderate and annually for One Choice Portfolio: Aggressive and One Choice Portfolio: Very Aggressive. Distributions from realized capital gains, if any, for all the funds are generally paid 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, to your home address or to another person or address by check.
37


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 an 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.
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.
38


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.
39


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; and (d) each class may have different exchange privileges.
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. The R Class has a 12b-1 plan. The plan provides for the funds to pay an annual fee of 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 fee to the financial intermediaries that make the class available. Because this fee may be used to pay for services that are not related to prospective sales of the funds, the R Class will continue to make payments under its plan even if it is closed to new investors. Because this fee is paid out of the funds’ assets on an ongoing basis, over time the fee will increase the cost of your investment and may cost you more than paying other types of sales charges. For additional information about the plan and its 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.
