Fund Summary

Investment Objective

The fund seeks long-term capital appreciation.

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.


Annual Fund Operating Expenses (expenses that you pay each year as a percentage of the value of your investment)	Institutional Class	G Class
Management Fee	0.33%	0.33%
Other Expenses	0.01%	0.01%
Total Annual Fund Operating Expenses	0.34%	0.34%
Fee Waiver	None	0.33%¹
Total Annual Fund Operating Expenses After Waiver	0.34%	0.01%

1 The advisor has agreed to waive the G Class’s management fee in its entirety. The advisor expects this waiver to remain in effect permanently and cannot terminate it without the approval of the Board of Trustees.

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, 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
Institutional Class	$35	$110	$191	$431
G Class	$1	$3	$6	$13

Portfolio Turnover

The fund pays transaction costs, such as commissions, when it buys and sells securities (or “turns over” its portfolio). A higher portfolio turnover rate may indicate higher transaction costs and may result in higher taxes when fund shares are held in a taxable account. These costs, which are not reflected in annual fund operating expenses or in the example, affect the fund’s 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

The fund invests primarily in a diverse group of companies related to emerging markets across market sectors, industry groups and countries. The fund may invest in companies of all market capitalizations.

The fund seeks securities of companies that it expects to have higher returns by placing an enhanced emphasis on securities of companies with smaller market capitalizations and securities of companies with higher profitability and value characteristics. Conversely, the fund seeks to underweight or exclude securities it expects to have lower returns, such as securities of larger companies with lower levels of profitability and less attractive value characteristics. To identify small capitalization companies with higher profitability and value characteristics, the portfolio managers use reported and/or estimated company financials and market data including, but not limited to, shares outstanding, book value and its components, cash flows from operations, and accruals. The portfolio managers define “value characteristics” mainly as adjusted book/price ratio (though other price to fundamental ratios may be considered). The portfolio managers define “profitability” mainly as adjusted cash from operations to book value ratio (though other ratios may be considered). The portfolio managers may also consider other factors when selecting a security, including industry classification, the past performance of the security relative to other securities, its liquidity, its float, and tax, governance or cost considerations, among others. When portfolio managers identify securities with the desired capitalization, profitability, value, and past performance characteristics, they seek to include and emphasize these securities in the broadly diversified portfolio. To determine the weight of a security within the portfolio, the portfolio managers use the market capitalization of the security relative to that of other eligible securities as a baseline, then overweight or underweight the security based on the characteristics described above. The portfolio managers may deemphasize or dispose of a security if it no longer has the desired market capitalization, profitability, or

value characteristics. When determining whether to deemphasize or dispose of a security, the portfolio managers will also consider, among other things, relative past performance, costs, and taxes. The portfolio managers review the criteria for inclusion in the portfolio on a regular basis to maintain a focus on the desired broad set of emerging markets companies.

Under normal market conditions, the fund will invest at least 80% of its assets in equity securities of companies related to emerging market countries. The fund considers an emerging market country to be any country other than a developed country. However, the fund generally intends to focus its investments in a subset of the emerging markets countries that comprise the MSCI Emerging Markets IMI Index. The countries comprising the index will change from time to time, but as of September 30, 2023 include: Brazil, Chile, China, Colombia, Czech Republic, Egypt, Greece, Hungary, India, Indonesia, Korea, Kuwait, Malaysia, Mexico, Peru, Philippines, Poland, Qatar, Saudi Arabia, South Africa, Taiwan, Thailand, Turkey and United Arab Emirates. To determine whether a company is related to an emerging market country, 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, the country in which the company was legally organized, and whether the company is in the fund’s benchmark—the MSCI Emerging Markets IMI. The weight given to each of these factors will vary depending on the circumstances in a given case. The fund may invest in securities that are denominated in foreign currencies and may also invest in foreign securities that are represented in the U.S. and other securities markets by American Depositary Receipts (ADRs), Global Depositary Receipts (GDRs), and other similar depositary arrangements.

The fund also may invest in derivative instruments such as futures contracts, currency forwards, and swap agreements. For example, the fund may use futures on securities and U.S. indices to gain exposure to equities to manage cash flows. The fund may also engage in securities lending and invest its collateral in eligible securities.

The portfolio managers continually analyze market and financial data to make buy, sell, and hold decisions. When buying or selling a security, the portfolio managers may consider the trade-off between expected returns of the security and implementation or tax costs of the trade in an attempt to gain trading efficiencies, avoid unnecessary risk, and enhance fund performance.

Principal Risks

•Equity Securities Risk — The value of equity securities, may fluctuate due to changes in investor perception of a specific issuer, changes in the general condition of the stock market, or occurrences of political or economic events that affect equity issuers and the market. Common stock prices may be particularly sensitive to rising interest rates, as the cost of capital rises and borrowing costs increase.

•Small-Cap Stock Risk — Smaller companies may have limited financial resources, product lines, markets and have less publicly available information. These securities may trade less frequently and in more limited volumes than larger companies’ securities, leading to higher transaction costs. Smaller companies also may be more sensitive to changing economic conditions, and investments in smaller foreign companies may experience more price volatility.

•Currency Risk — The fund could experience gains or losses solely on changes in the exchange rate between foreign currencies and the U.S. dollar.

•Emerging Markets Risk — Investing in emerging market countries generally is riskier than investing in foreign developed countries. Emerging market countries may have unstable governments, economies that are subject to sudden change, and significant volatility in their financial markets. These countries also may lack the legal, business and social framework to support securities markets. Additionally, certain jurisdictions do not provide the 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. As a result of the foregoing risks, the fund is intended for aggressive investors seeking significant gains through investments in foreign securities. Those investors must be willing and able to accept the significantly greater risks associated with the investment strategy that the fund will pursue. An investment in the fund is not appropriate for individuals with limited investment resources or who are unable to tolerate fluctuations in the value of their investment.

•Foreign Risk — Foreign securities are generally riskier than U.S. securities. Political events (such as civil unrest, national elections and imposition of exchange controls), social and economic events (such as labor strikes and rising inflation), 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.

•Greater China Risk — Investing in Chinese securities is riskier than investing in U.S. securities. 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. Due to Chinese governmental restrictions on foreign ownership of companies in certain industries, Chinese operating companies often use variable interest entity (VIE) structures to raise capital from international investors. Shares of VIEs are not equity ownership interests in Chinese operating companies. The Chinese government never explicitly approved these structures and thus could determine that the underlying contractual arrangements on which control of the VIE is based violate Chinese law. Such determination from the Chinese government could result in a loss in the value of an investment in a U.S.-listed company that utilizes the VIE structure. The Chinese market is

subject to less regulation and oversight than the U.S. market. U.S. regulators have limited ability to inspect international auditing standards of U.S. companies operating in China, thus there is substantially greater risk that disclosures will be incomplete or misleading and, in the event of investor harm, substantially less access to recourse.

•Depositary Receipts Risk — Investment in depositary receipts does not eliminate all the risks inherent in investing in securities of non-U.S. issuers. The market value of depositary receipts is dependent upon the market value of the underlying securities and fluctuations in the relative value of the currencies in which the depositary receipts and the underlying securities are quoted.

•Investment Process Risk — Stocks selected by the portfolio managers may perform differently than expected due to the portfolio managers’ judgments regarding the factors used, the weight placed on each factor, changes from the factors’ historical trends, and technical issues with the construction and implementation of the investment process (including, for example, data problems and/or software or other implementation issues). There is no guarantee that the investment process will result in effective investment decisions for the fund.

•Style Risk — If at any time the market is not favoring the fund’s investment style, the 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.

•Market Risk — The value of the fund’s shares will go up and down based on the performance of the companies whose securities it owns 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.

•Derivatives Risk — The use of derivative instruments involves risks different from, or possibly greater than, the risks associated with investing directly in securities and other traditional instruments. Derivatives are subject to a number of risks, including liquidity, interest rate, market, credit, and correlation risk. Derivatives used for hedging or risk management may not operate as intended, may expose the fund to other risks, and may be insufficient to protect the fund from the risks they were intended to hedge. Derivative transactions may expose the fund to the effects of leverage, which could increase the fund’s exposure to the market and magnify potential losses, particularly when derivatives are used to enhance return rather than offset risk. Derivatives can also be highly illiquid and difficult to unwind or value, and changes in the value of a derivative held by the fund may not correlate with the value of the underlying instrument or the fund’s other investments.

•Price Volatility Risk — The value of the fund’s shares may fluctuate significantly in the short term.

•Redemption Risk — The fund may need to sell securities at times it would not otherwise do so to meet shareholder redemption requests. Selling securities to meet such redemptions may cause the fund to experience a loss, increase the fund’s transaction costs or have tax consequences. To the extent that a large shareholder (including a fund of funds or 529 college savings plan) invests in the fund, the fund may experience relatively large redemptions as such shareholder reallocates its assets.

•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.

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 the Institutional 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 is the fund’s investment objective?

The fund seeks long-term capital appreciation.

The fund’s investment objective is a nonfundamental investment policy and may be changed by the Board of Trustees without approval by shareholders.

What are the fund’s principal investment strategies?

Equity securities in which the fund may invest include common stock, preferred stock, equity-equivalent securities, such as convertible securities, and derivative instruments that give exposure to equities, such as futures contracts, currency forwards, and swap agreements. For example, the fund may use futures on securities and U.S. indices to manage cash flows.

The fund may also engage in securities lending. Collateral received by the fund in connection with loaning its securities may consist of cash and U.S. government securities. Cash collateral may be invested in eligible securities.

In the event of adverse market, economic, political, or other conditions, the fund may take temporary defensive positions that are inconsistent with the fund’s principal investment strategies. To the extent the fund assumes a defensive position, it may not achieve its investment objective.

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

What are the principal risks of investing in the fund?

•Currency Risk — The fund could experience gains or losses solely on changes in the exchange rate between foreign currencies and the U.S. dollar.

•Greater China Risk — Investing in Chinese securities is riskier than investing in U.S. securities. Investing in China involves risk of loss due to nationalization, expropriation, and confiscation of assets and property.

Derivative transactions may expose the fund to the effects of leverage, which could increase the fund’s exposure to the market and magnify potential losses, particularly when derivatives are used to enhance return rather than offset risk. Derivatives can also be highly illiquid and difficult to unwind or value, and changes in the value of a derivative held by the fund may not correlate with the value of the underlying instrument or the fund’s other investments.

•Securities Lending Risk — Securities lending involves the risk of loss of rights in, or delay in recovery of, the loaned securities if the borrower fails to return the security loaned or becomes insolvent. Any decline in the value of a security while the security is loaned will adversely affect performance. These events could also result in adverse tax consequences.

•Price Volatility Risk — The value of the fund’s shares may fluctuate significantly in the short term.

•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.

Management

Who manages the fund?

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

The Board of Trustees

The Board of Trustees is responsible for overseeing the advisor’s management and operations of the fund pursuant to the management agreement. In performing their duties, Board members receive detailed information about the fund and its advisor regularly throughout the year and meet at least quarterly with management of the advisor to review reports about fund operations. The trustees’ role is to provide oversight and not to provide day-to-day management. The majority of the trustees are independent of the fund’s 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 Investment Advisor

The fund’s investment advisor is American Century Investment Management, Inc. (the advisor). The advisor has been managing investment companies since 1958 and is headquartered at 4500 Main Street, Kansas City, Missouri 64111. Avantis Investors is a division of American Century Investment Management, Inc.

The advisor is responsible for managing the investment portfolio of the fund and directing the purchase and sale of its investment securities. The advisor also arranges for transfer agency, custody and all other services necessary for the fund to operate.

For the services it provides to the Institutional Class of the fund, the advisor receives a unified management fee based on a percentage of the daily net assets of such class of shares of the fund. The amount of the fee is calculated daily and paid monthly in arrears. The advisor pays all expenses of managing and operating the fund, other than the management fee payable to the advisor, brokerage and other transaction fees and expenses relating to the acquisition and disposition of portfolio securities, acquired fund fees and expenses, interest (including without limitation borrowing costs and overdraft charges), taxes (including without limitation income, excise, transfer, and withholding taxes), litigation expenses (including without limitation litigation counsel fees and expenses), and extraordinary expenses. For the Institutional 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.

The G Class is subject to a contractual management fee that the advisor waives in its entirety. However, the advisor does receive a management fee from funds or client advisory accounts that invest in the G Class.


Management Fees Paid by the Fund to the Advisor As a Percentage of Average Net Assets for the Fiscal Year Ended August 31, 2023	Institutional Class	G Class
Avantis Emerging Markets Equity	0.33%	0.00%

A discussion regarding the basis for the Board of Trustees’ approval of the fund’s investment advisory agreement with the advisor is available in the fund’s annual report to shareholders dated August 31, 2023.

The Fund Management Team

Portfolio managers work as a team to manage funds. Portfolio managers regularly review portfolio holdings and potential purchase and sale activity. Team members buy and sell securities for a fund as they see fit, guided by the fund’s investment objective and strategy.

Fund Performance

The fund has the same management team and investment policies as the Avantis Emerging Markets Equity ETF. The fees and expenses of the funds are similar, and they are managed with substantially the same investment objective and strategies. Notwithstanding these general similarities, the Avantis Emerging Markets Equity Fund and the Avantis Emerging Markets Equity ETF are separate funds that have different investment performance. Differences in cash flows into the two funds, the size of their portfolios, and the specific investments held by the two funds cause performance to differ. Please consult the ETF prospectus for a description of the ETF, details on how the ETF is offered, and its associated fees.

Fundamental Investment Policies

Shareholders must approve any change to the fundamental investment policies contained in the statement of additional information. The Board of Trustees and/or the advisor may change any other policies, including the fund’s investment objective, or investment strategies described in this prospectus or otherwise used in the operation of the fund at any time, subject to applicable notice provisions.

Investing in the Fund

The 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.

Institutional Class

Institutional Class shares are available for purchase without sales charges or commissions by endowments, foundations, large institutional investors and financial intermediaries and by participants in certain employer-sponsored retirement plans. Institutional Class shares may be purchased or redeemed only through employer-sponsored retirement plans where a financial intermediary provides retirement recordkeeping services to plan participants.

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 the fund. For more information regarding employer-sponsored retirement plan types, please refer to Buying and Selling Fund Shares in the statement of additional information. American Century Investments 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.

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 fund. Please contact your financial intermediary or plan sponsor for a complete description of its policies. Copies of the fund’s annual report, semiannual report and statement of additional information are available from your financial intermediary or plan sponsor.

The fund has authorized certain financial intermediaries to accept orders on the fund’s 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 fund’s 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.

Institutional 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 Institutional Class shares in these programs may be required to pay a commission and/or other forms of compensation to the broker.

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

Additional Policies Affecting Your Investment

Eligibility for Institutional Class Shares

The Institutional Class shares are made available for purchase by individuals and large institutional shareholders such as bank trust departments, corporations, endowments, foundations and financial advisors that meet the fund’s minimum investment requirements and through employer-sponsored retirement plans where a financial intermediary provides retirement recordkeeping services to plan participants. For such plans to be eligible, plan level or omnibus accounts must be held on the books of the fund.

Minimum Initial Investment Amounts for Institutional Class

The minimum initial investment amount 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 initial 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 a minimum level of assets per participant, to be eligible to purchase Institutional 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 and Minimum Initial Investment Amounts for G Class

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.

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.

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.

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.

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. If the cumulative amount of frequent trading activity is significant relative to a fund’s net assets, the 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, the fund’s 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 fund’s Board of Trustees 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. 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 funds of funds (however shareholders of American Century’s funds of funds are subject to the limitations); 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 on 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 the 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 the fund is the current value of the class’s assets minus any liabilities, divided by the number of shares of the class outstanding.

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 Trustees 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.

Portfolio securities for which market quotations are readily available are valued at their market price. Equity securities and other equity instruments for which market quotations are readily available are valued at the last reported official closing price or sale price as of the time the NAV is determined. Portfolio securities primarily traded on foreign securities exchanges that are generally open later than the NYSE are valued at the last sale price reported 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. Circumstances that may cause the fund to determine that market quotations are not available or reliable include, but are not limited to:

•when there is a significant event subsequent to the market quotation;

•trading in a security has been halted during the trading day; or

•trading in a security is insufficient or did not take place due to a closure or holiday.

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 valuation 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.

Model-derived fair value factors may be applied to adjust the market quotation of certain foreign equity securities whose last closing price was before the time the NAV is determined. These factors are based on observable market data and are generally provided by an independent pricing service. Such factors are designed to estimate the price of the foreign equity security that would have prevailed at the time the NAV is determined.

Equity securities with no current day last sale or official close price may be priced at the mean of the bid and ask market quotations obtained from a listing exchange or an independent broker who is an established market maker in the security. The valuation designee may use third party pricing services to assist in the determination of fair value.

With respect to any portion of the fund’s assets that are invested in other mutual funds, the fund’s NAV will be calculated based upon the NAVs of such mutual funds. These mutual funds are required to explain the circumstances under which they will use fair value pricing and the effects of using fair value pricing in their prospectuses.

The value of any security or other asset denominated in a currency other than U.S. dollars is converted to U.S. dollars at the prevailing foreign exchange rate at the time the fund’s NAV is determined. Trading of securities in foreign markets 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 fund’s NAV is not calculated. So, the value of the fund’s portfolio may be affected on days when you will not be able to purchase, exchange or redeem fund shares.

Distributions

Federal tax laws require the fund to make distributions to its shareholders in order to qualify as a regulated investment company. Qualification as a regulated investment company means the fund 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. The fund generally expects to pay distributions from net income and capital gains, if any, once a year in December. The fund may make more frequent distributions, if necessary, to comply with Internal Revenue Code provisions.


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

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 a fund will vary depending on whether you own them through a taxable or tax-deferred account. Distributions by a fund of dividend and interest income, capital gains and other income it has generated through its 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. If you invest through a taxable account, you may be able to claim a foreign tax credit for any foreign income taxes paid by the fund. In order to qualify for this tax credit, certain requirements must be satisfied. Please consult the statement of additional information for a more complete discussion of the tax consequences of owning shares of the fund.

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 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.

Additional Information

Multiple Class Information

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

Except as described below, all classes of shares of the 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

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 fund’s 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 fund, 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 fund, 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 fund and may cover the expenses associated with attendance at such meetings, including travel costs. The distributor may also 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 and activities are intended to provide an incentive to intermediaries to sell the fund by educating them about the fund and helping defray the costs associated with offering the fund. These payments may create a conflict of interest by influencing the intermediary to recommend the fund 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 fund. As a result, the total expense ratio of the fund will not be affected by any such payments.

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