Fund Summary      

Investment Objective

The fund seeks capital growth.

Example

The example below is intended to help you compare the costs of investing in the fund with the costs of investing in other mutual funds. The example assumes that you invest $10,000 in the fund for the time periods indicated and then redeem all of your shares at the end of those periods and that you earn a 5% return each year. The example also assumes that the fund’s operating expenses remain the same, except that it reflects the rate and duration of any fee waivers noted in the table above. Although your actual costs may be higher or lower, based on these assumptions your costs would be:

	1 year	3 years
Investor Class	$164	$509
Institutional Class	$144	$447
A Class	$753	$1,127
C Class	$265	$813
R Class	$215	$662
R6 Class	$129	$400

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. Because the fund is new, the fund’s portfolio turnover rate is not available.

Principal Investment Strategies

The fund will invest at least 80% of its net assets in securities issued by small cap companies that are economically tied to emerging market countries.

The portfolio managers consider small cap companies to include companies with market capitalizations not greater than the largest company on the MSCI Emerging Markets Small Cap Index at the time of investment.

The fund considers an emerging market country to be any country that is located outside the following developed countries list, which is subject to change: Australia, Austria, Belgium, Bermuda, Canada, Denmark, Finland, France, Germany, Hong Kong, Ireland, Israel, Italy, Japan, the Netherlands, New Zealand, Norway, Portugal, Singapore, Spain, Sweden, Switzerland, the United Kingdom and the United States. The fund may also invest in frontier markets (emerging market countries at an earlier stage of development).

The portfolio managers look for stocks of companies they believe will increase in value over time, using an investment strategy developed by the fund’s investment advisor. In implementing this strategy, the portfolio managers make their investment decisions based primarily on their analysis of individual companies, rather than on economic forecasts. Management of the fund is based on the belief that, over the long term, stock price movements follow growth in earnings, revenues and/or cash flow. The portfolio managers use a variety of analytical research tools and techniques to identify the stocks of companies that meet their investment criteria. Under normal market conditions, the fund’s portfolio will primarily consist of securities of companies whose earnings or revenues are not only growing, but growing at an accelerating pace. 

The fund may engage in active and frequent trading of portfolio securities to achieve its principal investment strategies. This may cause higher transaction costs and may affect performance. It may also result in the realization and distribution of capital gains.

Principal Risks

• Foreign Risk — The fund invests in foreign securities, which are generally riskier than U.S. securities. As a result, the fund is subject to foreign risk, meaning that political events (such as civil unrest, national elections and imposition of exchange controls), social and economic events (such as labor strikes and rising inflation), and natural disasters 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.

• Small-Cap Stock Risk — Investing in securities of smaller foreign companies generally presents unique risks in addition to the typical risks of investing in foreign securities. Smaller companies may have limited financial resources, product lines, markets and have less publicly available information. In addition, securities of smaller companies may trade less frequently and in more limited volumes than securities of larger companies, which could lead to higher transaction costs. Smaller companies also may be more sensitive to changing economic conditions. These factors may cause investments in smaller foreign companies to experience more price volatility.

• Currency Risk — Because the fund generally invests in securities denominated in foreign currencies, the fund is subject to currency risk, meaning that the fund could experience gains or losses based solely on changes in the exchange rate between foreign currencies and the U.S. dollar.

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

• Frontier Emerging Markets Risk — Frontier emerging market countries generally have smaller economies and even less developed capital markets than traditional emerging markets and, as a result, the risks of investing in an frontier emerging market are magnified. Unique risks include: potential for extreme price volatility and illiquidity, government control of certain industries or companies and limitations on foreign investment, economic and political instability, and relatively new and unsettled securities laws.

• Growth Stocks — Investments in growth stocks may be more volatile than other stocks and the overall stock market. These stocks are typically priced higher than other stocks because of their growth potential, which may or may not be realized.

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

3

• 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.

• Redemption Risk — The fund may need to sell securities at times it would not otherwise do so in order 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.

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

• Principal Loss — 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

Because the fund is new, the fund’s performance history is not available. When the fund has a full calendar year of investment results, this section will feature charts that show annual total returns, highest and lowest quarterly returns and average annual total returns for the fund. This information will indicate the volatility of the fund’s historical returns from year to year. For current performance information, please visit americancentury.com. 

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

Portfolio Management

Investment Advisor

American Century Investment Management, Inc.

Portfolio Managers

Patricia Ribeiro, Vice President and Senior Portfolio Manager, has been a member of the team that manages the fund since 2006.

Purchase and Sale of Fund Shares

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

Unless otherwise specified below, the minimum initial investment amount to open an account is $2,500 ($2,000 for Coverdell Education Savings Accounts). Investors opening accounts through financial intermediaries may open an account with $250 for all classes except the Institutional and R6 Classes, but the financial intermediaries may require their clients to meet different investment minimums. The minimum may be waived for broker-dealer sponsored wrap program accounts, fee based accounts, and accounts through bank/trust and wealth management advisory organizations.

The minimum initial investment amount for Institutional Class is generally $5 million ($3 million for endowments and foundations), but the minimum may be waived if you, or your financial intermediary if you invest through an omnibus account, have an aggregate investment in the American Century family of funds of $10 million or more.

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

For all share classes, there is no minimum initial investment amount for certain employer-sponsored retirement plans, however, financial intermediaries or plan recordkeepers may require plans to meet different minimums. For purposes of fund minimums, employer-sponsored retirement plans do not include SEP IRAs, SIMPLE IRAs or SARSEPs.

There is a $50 minimum for subsequent purchases, except that there is no subsequent purchase minimum for financial intermediaries or employer-sponsored retirement plans.

4

Tax Information

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

Payments to Broker-Dealers and Other Financial Intermediaries

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

Objectives, Strategies and Risks

What is the fund’s investment objective?

The fund seeks capital growth. The fund’s investment objective is a non-fundamental policy and may be changed by the Board of Directors without shareholder approval upon 60 days’ notice to shareholders.

What are the fund’s principal investment strategies?

The fund will invest at least 80% of its net assets in securities issued by small cap companies that are economically tied to emerging market countries.

The portfolio managers consider small cap companies to include companies with market capitalizations not greater than the largest company on the MSCI Emerging Markets Small Cap Index at the time of investment. Though market capitalization will change from time to time, as of [January 1, 2016], the market capitalization of the largest company on the MSCI Emerging Markets Small Cap Index was [_________]. The fund may continue to hold securities of companies whose market capitalization no longer meets this definition after purchase.

The fund considers a security to be an emerging markets security if its issuer is located outside the following developed countries list, which is subject to change: Australia, Austria, Belgium, Bermuda, Canada, Denmark, Finland, France, Germany, Hong Kong, Ireland, Israel, Italy, Japan, the Netherlands, New Zealand, Norway, Portugal, Singapore, Spain, Sweden, Switzerland, the United Kingdom and the United States. In determining where a company is located, the portfolio managers will consider various factors, including where the company is headquartered, where the company’s principal operations are located, where the company’s revenues are derived, where the principal trading market is located and the country in which the company was legally organized. The weight given to each of these factors will vary depending on the circumstances in a given case.

The fund may also invest in frontier markets (emerging market countries at an earlier stage of development). Frontier markets generally include any country that is included on the MSCI Frontier Markets Index, or similar market indices, or any country that in the portfolio manager’s opinion, has similar characteristics regardless of inclusion in an index.

The portfolio managers look for stocks of companies they believe will increase in value over time, using an investment strategy developed by the fund’s investment advisor. In implementing this strategy, the portfolio managers use a bottom-up approach to stock selection. This means that the managers make their investment decisions based primarily on their analysis of individual companies, rather than on broad economic forecasts. Management of the fund is based on the belief that, over the long term, stock price movements follow growth in earnings, revenues and/or cash flow.

Using a variety of analytical research tools, the portfolio managers track financial information for individual companies to identify and evaluate trends in earnings, revenues and other business fundamentals. Under normal market conditions, the fund’s portfolio will primarily consist of securities of companies whose earnings or revenues are not only growing, but growing at an accelerating pace. This includes companies whose growth rates, although still negative, are less negative than prior periods, and companies whose growth rates are expected to accelerate. Other analytical techniques help identify additional signs of business improvement, such as increasing cash flows, or other indications of the relative strength of a company’s business. These techniques help the portfolio managers buy or hold the stocks of companies they believe have favorable growth prospects and sell the stocks of companies whose characteristics no longer meet their criteria.

In addition to locating strong companies with earnings, revenue and/or cash flow growth, the portfolio managers believe that it is important to diversify the fund’s holdings across different countries and geographical regions in an effort to manage the risks of an international portfolio. For this reason, the portfolio managers also consider the prospects for relative economic growth among countries or regions, economic and political conditions, expected inflation rates, currency exchange fluctuations and tax considerations when making investments.

The portfolio managers do not attempt to time the market. Instead, under normal market conditions, they intend to keep the fund essentially fully invested in stocks regardless of the movement of stock prices generally. However, the fund can purchase other types of securities as well, such as forward currency exchange contracts, notes, bonds and other debt securities of companies, and obligations of domestic or foreign governments and their agencies.

Futures contracts, a type of derivative instrument, can help the fund’s cash assets remain liquid while performing more like stocks. The fund has a policy governing futures contracts and similar derivative instruments to help manage the risk of these types of investments. A complete description of the derivatives policy is included in the statement of additional information.

In the event of exceptional market or economic conditions, the fund may, as a temporary defensive measure, invest all or a substantial portion of its assets in cash or high-quality, short-term debt securities, denominated in U.S. dollars or another currency. To the extent the fund assumes a defensive position, however, it will not be pursuing its objective of capital growth.

6

The fund may engage in active and frequent trading of portfolio securities to achieve its principal investment strategies. A higher portfolio turnover rate may indicate higher transaction costs and may affect the fund’s performance. Higher portfolio turnover also may result in the realization and distribution of capital gains, including short-term capital gains.

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?

Investing in foreign securities has certain unique risks that make it generally riskier than investing in U.S. securities. These risks include increased exposure to political, social and economic events in world markets; limited availability of public information about a company; less-developed trading markets and regulatory practices; and a lack of uniform financial reporting practices compared to those that apply in the United States. Securities of foreign issuers may be less liquid, more volatile and harder to value than U.S. securities.

Investing in securities of smaller foreign companies generally presents unique risks in addition to the typical risks of investing in foreign securities. Smaller companies may have limited financial resources, product lines, markets and have less publicly available information. In addition, securities of smaller companies may trade less frequently and in more limited volumes than securities of larger companies, which could lead to higher transaction costs. Smaller companies also may be more sensitive to changing economic conditions. These factors may cause investments in smaller foreign companies to experience more price volatility.

In addition, investments in foreign countries are subject to currency risk, meaning that because the fund’s investments are generally denominated in foreign currencies, the fund could experience gains or losses based solely on changes in the exchange rate between foreign currencies and the U.S. dollar.

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

Frontier emerging market countries generally have smaller economies and even less developed capital markets than traditional emerging markets and, as a result, the risks of investing in an frontier emerging market are magnified. Unique risks include: potential for extreme price volatility and illiquidity, government control of certain industries or companies and limitations on foreign investment, economic and political instability, and relatively new and unsettled securities laws.

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 manager’s assessment 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 market.

Market performance tends to be cyclical, and, in various cycles, certain investment styles may fall in and out of favor. If at any time the market is not favoring the fund’s growth 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.

The value of a 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.

The fund may need to sell securities at times it would not otherwise do so in order to meet shareholder redemption requests. The 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 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. Although the advisor seeks to minimize the impact of such transactions where possible, the fund’s performance may be adversely affected.

The portfolio managers may buy a large amount of a company’s stock quickly, and may dispose of it quickly if the company’s earnings or revenues decline. While the managers believe this strategy provides substantial appreciation potential over the long term, in the short term it can create a significant amount of share price volatility. This volatility can be greater than that of the average stock fund.

7

The fund’s performance also may be affected by investments in initial public offerings (IPOs). The impact of IPOs on a fund’s performance depends on the strength of the IPO market and the size of the fund. IPOs may have less impact on a fund’s performance as its assets grow.

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.

8

Management

Who manages the fund?

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

The Board of Directors

The Board of Directors 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 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 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 mutual funds since 1958 and is headquartered at 4500 Main Street, Kansas City, Missouri 64111.

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 fund, the advisor receives a unified management fee based on a percentage of the daily net assets of each class of shares of the fund. The amount of the fee is calculated daily and paid monthly in arrears. Out of that fee, the advisor pays all expenses of managing and operating the fund except brokerage expenses, taxes, interest, fees and expenses of the independent directors (including legal counsel fees), extraordinary expenses, and expenses incurred in connection with the provision of shareholder services and distribution services under a plan adopted pursuant to Rule 12b-1 under the Investment Company Act of 1940. For all classes other than R6 Class, the advisor may pay unaffiliated third parties who provide recordkeeping and administrative services that would otherwise be performed by an affiliate of the advisor.

The fund will pay the advisor a unified management fee of 1.60% for Investor, A, C and R Class, a unified management fee of 1.40% for Institutional Class and a unified management fee of 1.25% for R6 Class.

A discussion regarding the basis for the Board of Directors’ approval of the fund’s investment advisory agreement with the advisor will be available in the fund’s annual report to shareholders dated November 30, 2016.

The Fund Management Team

The advisor uses teams of portfolio managers and analysts to manage funds. The teams meet regularly to review portfolio holdings and discuss 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.

The portfolio manager primarily responsible for the day-to-day management of the fund is identified below:

Patricia Ribeiro

Ms. Ribeiro, Vice President and Senior Portfolio Manager, has been a member of the team that manages the fund since joining American Century Investments in 2006 as a portfolio manager. She has a bachelor’s degree in accounting from Rutgers University.

The statement of additional information provides additional information about the accounts managed by the portfolio managers, their structure of compensation, and their ownership of fund securities.

Fundamental Investment Policies

Fundamental investment policies contained in the statement of additional information may not be changed without shareholder approval. The Board of Directors and/or the advisor may change any other policies or investment strategies described in this prospectus or otherwise used in the operation of the fund, including the fund’s investment objective, at any time.

Investing Through a Financial Intermediary

The funds 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.

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

Investor Class

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

Institutional Class

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

A Class

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

C Class

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

R Class

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

R6 Class

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

12

Calculation of Sales Charges

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

A Class

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

Purchase Amount	Sales Charge as a % of Offering Price	Sales Charge as a % of Net Amount Invested	Dealer Commission as a % of Offering Price
Less than $50,000	5.75%	6.10%	5.00%
$50,000 - $99,999	4.75%	4.99%	4.00%
$100,000 - $249,999	3.75%	3.90%	3.25%
$250,000 - $499,999	2.50%	2.56%	2.00%
$500,000 - $999,999	2.00%	2.04%	1.75%
$1,000,000 - $3,999,999	0.00%	0.00%	1.00%
$4,000,000 - $9,999,999	0.00%	0.00%	0.50%
$10,000,000 or more	0.00%	0.00%	0.25%

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

Reductions and Waivers of Sales Charges for A Class

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

You and your immediate family (which includes your spouse or domestic partner and children, step-children, parents or step-parents of you, your spouse or domestic partner) may combine investments in any share class of any American Century Investments fund (excluding certain assets in money market accounts, but including, beginning January 1, 2011, account assets invested in Qualified Tuition Programs under Section 529) to reduce your A Class sales charge in the following ways:

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

• Certain trust accounts

• Solely controlled business accounts

• Single-participant retirement plans

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

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

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

Rights of Accumulation. You may take into account the current value of your existing holdings, less any commissionable shares in the money market funds, in any share class of any American Century Investments fund to qualify for a reduced A Class sales charge.

13

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

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

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

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

• Current officers, directors and employees of American Century Investments

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

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

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

C Class

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

American Century Investments generally limits purchases of C Class shares to investors whose aggregate investments in American Century Investments funds are less than $1,000,000. However, it is your responsibility to inform your financial intermediary and/or American Century Investments at the time of purchase of any accounts to be aggregated, including investments in any share class of any American Century Investments fund (excluding certain assets in money market accounts, but including, beginning January 1, 2011, account assets invested in Qualified Tuition Programs under Section 529) in accounts held by you and your immediate family members (which includes your spouse or domestic partner and children, step-children, parents or step-parents of you, your spouse or domestic partner). Once you reach this limit, you should work with your financial intermediary to determine what share class is most appropriate for additional purchases.

Calculation of Contingent Deferred Sales Charge (CDSC)

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

14

CDSC Waivers 

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

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

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

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

• required minimum distributions from retirement accounts upon reaching age 70½

• tax-free returns of excess contributions to IRAs

• redemptions due to death or post-purchase disability

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

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

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

Reinstatement Privilege 

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

Employer-Sponsored Retirement Plans

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

Exchanging Shares

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

• The exchange is for a minimum of $100

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

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

Some shares are subject to a redemption fee if they are exchanged in this manner (see Redemptions under Additional Policies Affecting Your Investment).

15

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.

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 (other than Institutional and R6 Classes)

Unless otherwise specified below, the minimum initial investment amount to open an account is $2,500. 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 (CESA)	$2,0001
Employer-sponsored retirement plans2	No minimum

¹  The minimum initial investment for shareholders investing through financial intermediaries is $250. Financial intermediaries may have different minimums for their clients.

²  For this purpose, employer-sponsored retirement plans do not include SEP IRAs, SIMPLE IRAs or SARSEPs. 

Subsequent Purchases

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

Eligibility for Institutional Class Shares

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

Minimum Initial Investment Amounts (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, or your financial intermediary if you invest through an omnibus account, have an aggregate investment in our family of funds of $10 million or more ($5 million for endowments and foundations), or in other situations as determined by American Century Investments. 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. 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, in order to be eligible to purchase Institutional Class shares.

Eligibility for R6 Class Shares

The fund’s R6 Class shares are generally available only through employer-sponsored retirement plans where a financial intermediary provides retirement recordkeeping services to plan participants. To be eligible, plan level or omnibus accounts must be held on the books of the fund. R6 Class shares also are available to funds of funds advised by American Century and unaffiliated funds of funds sold primarily to the employer-sponsored retirement plan market.

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

17

Minimum Initial Investment Amounts (R6 Class)

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

Redemptions

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

However, we reserve the right to delay delivery of redemption proceeds 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. 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.

In addition, we reserve the right to honor certain redemptions with securities, rather than cash, as described in the next section.

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. The portfolio managers would select these securities from the fund’s portfolio.

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.

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.

Redemption of Shares in Accounts Below Minimum

If your account balance falls below the minimum initial investment amount for any reason, 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. Shares redeemed in this manner may be subject to a redemption fee, if held less than a specified number of days (see Redemptions under Additional Policies Affecting Your Investment). Please note that shares redeemed in this manner may be subject to a sales charge if held less than the applicable time period. You also may incur tax liability as a result of the redemption. For Institutional Class shares, we reserve the right to convert your shares to Investor Class shares of the same fund. The Investor Class shares have a unified management fee that is 0.20 percentage points higher than the Institutional Class.

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.

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

18

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 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, imposing redemption fees on certain funds, and using fair value pricing when current market prices are not readily available. As a heightened measure for the fund, the board has approved the imposition of a redemption fee for shares held less than a specified number of days. See Redemption Fee under Additional Policies Affecting Your Investment. 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.

19

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, 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. 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.

20

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 the fund is the current value of the fund’s assets attributable to the class, minus any liabilities, divided by the number of shares of the class outstanding.

The fund values portfolio securities for which market quotations are readily available at their market price. As a general rule, equity securities listed on a U.S. exchange are valued at the last current reported sale price as of the time of valuation. Portfolio securities primarily traded on foreign securities exchanges are generally valued at the preceding closing values of such securities on the foreign exchange where primarily traded or at the time the fund’s NAV is determined, if that is earlier. That value is then converted to U.S. dollars at the prevailing foreign exchange rate. Securities listed on the NASDAQ National Market System (Nasdaq) are valued at the Nasdaq Official Closing Price (NOCP), as determined by Nasdaq, or lacking an NOCP, at the last current reported sale price as of the time of valuation. Securities that are neither listed on a securities exchange or traded over the counter may be priced using the mean of the bid and asked prices obtained from an independent broker who is an established market maker in the security. The fund may use third party pricing services to assist in the determination of market value.

If the fund determines that the market price for a portfolio security is not readily available or that the valuation methods mentioned above do not reflect the security’s fair value, such security is valued as determined in good faith by the fund’s board or its designee, in accordance with procedures adopted by the fund’s board. Circumstances that may cause the fund to use alternate procedures to value a security include, but are not limited to:

• if, after the close of the foreign exchange on which a portfolio security is principally traded, but before the close of the NYSE, an event occurs that may materially affect the value of the security;

• a debt security has been declared in default; or

• trading in a security has been halted during the trading day.

If such circumstances occur, the fund 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 procedures adopted by the fund’s board.

The effect of using fair value determinations is that the fund’s NAV will be based, to some degree, on security valuations that the board or its designee believes are fair rather than being solely determined by the market.

With respect to any portion of the fund’s assets that are invested in one or more open-end management investment companies that are registered with the SEC (known as registered investment companies), the fund’s NAV will be calculated based upon the NAVs of such registered investment companies. These registered investment companies are required by law to explain the circumstances under which they will use fair value pricing and the effects of using fair value pricing in their prospectuses.

Securities and other assets quoted in foreign currencies are valued in U.S. dollars based on the prevailing exchange rates on that day.

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.

21

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 investment securities. The fund generally expects to pay distributions from net income and capital gains, if any, once a year. 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 stock, 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.

22

Taxes

Some of the tax consequences of owning shares of the fund will vary depending on whether you own them through a taxable or tax-deferred account. Distributions by the 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 a fund from the stock of a domestic or qualifying foreign corporation, provided that the fund has held the stock for a required holding period.

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 a 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.

23

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.

24

Multiple Class Information

The fund offers multiple classes of shares. The classes have different fees, expenses and/or minimum investment requirements. The difference in the fee structures between the classes is the result of their separate arrangements for shareholder and distribution services. It is not the result of any difference in advisory or custodial fees or other expenses related to the management of the fund’s assets, which do not vary by class. The Institutional Class and R6 Class shareholders do not require the same level of shareholder and administrative services from the advisor as shareholders of the other classes. In addition, American Century does not pay any service, distribution or administrative fees to financial intermediaries for R6 Class shares. As a result, the advisor is able to charge these classes lower unified management fees. 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; (d) each class may have different exchange privileges; and (e) the Institutional Class may provide for conversion from that class into shares of the Investor Class of the same fund.

Service, Distribution and Administrative Fees

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

Certain financial intermediaries perform recordkeeping and administrative services for their clients that would otherwise be performed by American Century Investments’ transfer agent. In some circumstances, the advisor will pay such service providers a fee for performing those services. Also, the advisor and the 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 sponsor seminars and conferences designed to educate intermediaries about the fund and may cover the expenses associated with attendance at such meetings, including travel costs. 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 the available assets of the advisor and distributor, and not 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 service, distribution or administrative fees to financial intermediaries on R6 Class shares.

Fund Summary

Investment Objective

The fund seeks capital growth.

Fees and Expenses

²  Other expenses are based on estimated amounts for the current fiscal year.

Example

The example below is intended to help you compare the costs of investing in the fund with the costs of investing in other mutual funds. The example assumes that you invest $10,000 in the fund for the time periods indicated and then redeem all of your shares at the end of those periods and that you earn a 5% return each year. The example also assumes that the fund’s operating expenses remain the same, except that it reflects the rate and duration of any fee waivers noted in the table above. Although your actual costs may be higher or lower, based on these assumptions your costs would be:

	1 year	3 years
Investor Class	$127	$394
Institutional Class	$106	$331
A Class	$718	$1,020
C Class	$228	$701
R Class	$177	$549
R6 Class	$91	$284

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. Because the fund is new, the fund’s portfolio turnover rate is not available.

2

Principal Investment Strategies

The fund invests primarily in securities of companies located in at least three developed countries world-wide (excluding the United States). The portfolio managers look for stocks of companies they believe will increase in value over time, using an investment strategy developed by the fund’s investment advisor. In implementing this strategy, the portfolio managers make their investment decisions based primarily on their analysis of individual companies, rather than on broad economic forecasts. Management of the fund is based on the belief that, over the long term, stock price movements follow growth in earnings, revenues and/or cash flow. The portfolio managers use a variety of analytical research tools and techniques to identify the stocks of companies that meet their investment criteria. Under normal market conditions, the fund’s portfolio will primarily consist of securities of companies whose earnings or revenues are not only growing, but growing at an accelerating pace. The fund normally invests in a relatively limited number of companies, generally 35–50.

The fund may engage in active and frequent trading of portfolio securities to achieve its principal investment strategies. This may cause higher transaction costs and may affect performance. It may also result in the realization and distribution of capital gains.

Principal Risks

• Foreign Risk – The fund invests primarily in foreign securities, which are generally riskier than U.S. securities. As a result the fund is subject to foreign risk, meaning that political events (such as civil unrest, national elections and imposition of exchange controls), social and economic events (such as labor strikes and rising inflation), and natural disasters 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.

• Focused Portfolio Risk – Investing in a limited number of companies carries more risk because changes in the value of a single company may have a more significant effect, either negative or positive on the fund’s value.

• Nondiversification – The fund is nondiversified. This gives the portfolio managers the flexibility to hold large positions in single issuers. A price change in the securities of such an issuer may have a greater impact on the fund’s value than would be the case in a diversified fund.

• Currency Risk – Because the fund generally invests in securities denominated in foreign currencies, the fund is subject to currency risk, meaning that the fund could experience gains or losses based solely on changes in the exchange rate between foreign currencies and the U.S. dollar.

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

• Growth Stocks – Investments in growth stocks may be more volatile than other stocks and the overall stock market. These stocks are typically priced higher than other stocks because of their growth potential, which may or may not be realized.

• Style Risk – If at any time the market is not favoring the fund’s growth 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.

• Redemption Risk – The fund may need to sell securities at times it would not otherwise do so in order 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.

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

• Principal Loss – 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

Because the fund is new, the fund’s performance history is not available. When the fund has a full calendar year of investment results, this section will feature charts that show annual total returns, highest and lowest quarterly returns and average annual total returns for the fund. This information will indicate the volatility of the fund’s historical returns from year to year. For current performance information, please visit americancentury.com. 

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

Purchase and Sale of Fund Shares

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

Unless otherwise specified below, the minimum initial investment amount to open an account is $2,500 ($2,000 for Coverdell Education Savings Accounts). Investors opening accounts through financial intermediaries may open an account with $250 for all classes except the Institutional and R6 Classes, but the financial intermediaries may require their clients to meet different investment minimums. The minimum may be waived for broker-dealer sponsored wrap program accounts, fee based accounts, and accounts through bank/trust and wealth management advisory organizations.

The minimum initial investment amount for Institutional Class is generally $5 million ($3 million for endowments and foundations), but the minimum may be waived if you, or your financial intermediary if you invest through an omnibus account, have an aggregate investment in the American Century family of funds of $10 million or more.

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

For all share classes, there is no minimum initial investment amount for certain employer-sponsored retirement plans, however, financial intermediaries or plan recordkeepers may require plans to meet different minimums. For purposes of fund minimums, employer-sponsored retirement plans do not include SEP IRAs, SIMPLE IRAs or SARSEPs.

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

Objectives, Strategies and Risks

What is the fund’s investment objective?

The fund seeks capital growth. The fund’s investment objective is a non-fundamental policy and may be changed by the Board of Directors without shareholder approval upon 60 days’ notice to shareholders.

What are the fund’s principal investment strategies?

The fund’s assets will be primarily invested in equity securities of companies located in at least three developed countries (excluding the United States).

The portfolio managers look for stocks of companies they believe will increase in value over time, using an investment strategy developed by the fund’s investment advisor. In implementing this strategy, the portfolio managers use a bottom-up approach to stock selection. This means that the managers make their investment decisions based primarily on their analysis of individual companies, rather than on broad economic forecasts. Management of the fund is based on the belief that, over the long term, stock price movements follow growth in earnings, revenues and/or cash flow. The fund normally invests in a relatively limited number of companies, generally 35–50.

Using a variety of analytical research tools, the portfolio managers track financial information for individual companies to identify and evaluate trends in earnings, revenues and other business fundamentals. Under normal market conditions, the fund’s portfolio will primarily consist of securities of companies whose earnings or revenues are not only growing, but growing at an accelerating pace. This includes companies whose growth rates, although still negative, are less negative than prior periods, and companies whose growth rates are expected to accelerate. Other analytical techniques help identify additional signs of business improvement, such as increasing cash flows, or other indications of the relative strength of a company’s business. These techniques help the portfolio managers buy or hold the stocks of companies they believe have favorable growth prospects and sell the stocks of companies whose characteristics no longer meet their criteria.

In addition to locating strong companies with earnings and revenue growth, the portfolio managers believe that it is important to diversify the fund’s holdings across different countries and geographical regions in an effort to manage the risks of an international portfolio. For this reason, the portfolio managers also consider the prospects for relative economic growth among countries or regions, economic and political conditions, expected inflation rates, currency exchange fluctuations and tax considerations when making investments.

While the fund will invest primarily in securities of companies located in developed countries, the fund may also invest in securities issued by companies located in emerging market countries.

The fund considers a security to be an emergingmarkets security if its issuer is located outside the following developed countries list, which is subject to change: Australia, Austria, Belgium, Bermuda, Canada, Denmark, Finland, France, Germany, Hong Kong, Ireland, Israel, Italy, Japan, the Netherlands, New Zealand, Norway, Portugal, Singapore, Spain, Sweden, Switzerland, the United Kingdom and the United States.

In determining where a company is located, the portfolio managers will consider various factors, including where the company is headquartered, where the company’s principal operations are located, where the company’s revenues are derived, where the principal trading market is located and the country in which the company was legally organized. The weight given to each of these factors will vary depending on the circumstances in a given case.

The portfolio managers do not attempt to time the market. Instead, under normal market conditions, they intend to keep the fund essentially fully invested in stocks regardless of the movement of stock prices generally. However, the fund can purchase other types of securities as well, such as forward currency exchange contracts, notes, bonds and other debt securities of companies, and obligations of domestic or foreign governments and their agencies.

Futures contracts, a type of derivative instrument, can help the fund’s cash assets remain liquid while performing more like stocks. The fund has a policy governing futures contracts and similar derivative instruments to help manage the risk of these types of investments. A complete description of the derivatives policy is included in the statement of additional information.

In the event of exceptional market or economic conditions, the fund may, as a temporary defensive measure, invest all or a substantial portion of its assets in cash or high-quality, short-term debt securities, denominated in U.S. dollars or another currency. To the extent the fund assumes a defensive position, however, it will not be pursuing its objective of capital growth.

The fund may engage in active and frequent trading of portfolio securities to achieve its principal investment strategies. A higher portfolio turnover rate may indicate higher transaction costs and may affect the fund’s performance. Higher portfolio turnover also may result in the realization and distribution of capital gains, including short-term capital gains.

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?

Investing in foreign securities has certain unique risks that make it generally riskier than investing in U.S. securities. These risks include increased exposure to political, social and economic events in world markets; limited availability of public information about a company; less-developed trading markets and regulatory practices; and a lack of uniform financial reporting practices compared to those that apply in the United States. Securities of foreign issuers may be less liquid, more volatile and harder to value than U.S. securities.

Investing in a limited number of companies carries more risk because changes in the value of a single company may have a more significant effect, either negative or positive on the fund’s value.

The fund is nondiversified. This means the fund has the flexibility to hold large positions in single issuers. A price change in the securities of such an issuer may have a greater impact on the fund’s value than would be the case if the fund were diversified.

Investments in foreign countries are also subject to currency risk, meaning that because the fund’s investments are generally denominated in foreign currencies, the fund could experience gains or losses based solely on changes in the exchange rate between foreign currencies and the U.S. dollar.

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

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 manager’s assessment 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 market.

Market performance tends to be cyclical, and, in various cycles, certain investment styles may fall in and out of favor. If at any time the market is not favoring the fund’s growth 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.

The value of the fund’s shares depends on the value of the stocks and other securities it owns. The value of the individual securities the 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.

The fund may need to sell securities at times it would not otherwise do so in order to meet shareholder redemption requests. The 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 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. Although the advisor seeks to minimize the impact of such transactions where possible, the fund’s performance may be adversely affected.

The portfolio managers may buy a large amount of a company’s stock quickly, and may dispose of it quickly if the company’s earnings or revenues decline. While the managers believe this strategy provides substantial appreciation potential over the long term, in the short term it can create a significant amount of share price volatility. This volatility can be greater than that of the average stock fund.

The fund’s performance also may be affected by investments in initial public offerings (IPOs). The impact of IPOs on a fund’s performance depends on the strength of the IPO market and the size of the fund. IPOs may have less impact on a fund’s performance as its assets grow.

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.

Management

Who manages the fund?

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

The Board of Directors

The Board of Directors 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 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 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 mutual funds since 1958 and is headquartered at 4500 Main Street, Kansas City, Missouri 64111.

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 fund, the advisor receives a unified management fee based on a percentage of the daily net assets of each class of shares of the fund. The amount of the fee is calculated daily and paid monthly in arrears. Out of that fee, the advisor pays all expenses of managing and operating the fund except brokerage expenses, taxes, interest, fees and expenses of the independent directors (including legal counsel fees), extraordinary expenses, and expenses incurred in connection with the provision of shareholder services and distribution services under a plan adopted pursuant to Rule 12b-1 under the Investment Company Act of 1940. For all classes other than R6 Class, the advisor may pay unaffiliated third parties who provide recordkeeping and administrative services that would otherwise be performed by an affiliate of the advisor.

The fund will pay the advisor a unified management fee of 1.23% for Investor, A, C and R Class, a unified management fee of 1.03% for Institutional Class and a unified management fee of 0.88% for R6 Class.

A discussion regarding the basis for the Board of Directors’ approval of the fund’s investment advisory agreement with the advisor will be available in the fund’s annual report to shareholders dated November 30, 2016.

The Fund Management Team

The advisor uses teams of portfolio managers and analysts to manage funds. The teams meet regularly to review portfolio holdings and discuss 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.

The portfolio managers on the investment team who are jointly and primarily responsible for the day-to-day management of the fund are identified below.

Rajesh Gandhi

Mr. Gandhi, Vice President and Senior Portfolio Manager, has been a member of the team that manages the fund since he joined American Century Investments in 2002 as an investment analyst. He became a portfolio manager in 2008. He has a bachelor’s degree in finance and real estate from the University of Wisconsin. He is a CFA charterholder.

James G. Gendelman

Mr. Gendelman, Vice President and Portfolio Manager, has been a member of the team that manages the fund since joining American Century Investments in 2015. Prior to joining American Century, he was a fund co-manager at Marsico Capital Management, LLC. He has a bachelor’s degree in accounting from Michigan State University and an MBA in finance from the Booth Graduate School of Business at the University of Chicago.

The statement of additional information provides additional information about the accounts managed by the portfolio managers, the structure of their compensation, and their ownership of fund securities.

Fundamental Investment Policies

Fundamental investment policies contained in the statement of additional information may not be changed without shareholder approval. The Board of Directors and/or the advisor may change any other policies and investment strategies described in this prospectus or otherwise used in the operation of the fund, including the fund’s investment objective, at any time.

Investing Through a Financial Intermediary

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

Financial intermediariesinclude banks, broker-dealers, insurance companies, plan sponsors and financial professionals. 

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

Investor Class

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

Institutional Class

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

A Class

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

C Class

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

R Class

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

R6 Class

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

10

Calculation of Sales Charges

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

A Class

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

Purchase Amount	Sales Charge as a % of Offering Price	Sales Charge as a % of Net Amount Invested	Dealer Commission as a % of Offering Price
Less than $50,000	5.75%	6.10%	5.00%
$50,000 - $99,999	4.75%	4.99%	4.00%
$100,000 - $249,999	3.75%	3.90%	3.25%
$250,000 - $499,999	2.50%	2.56%	2.00%
$500,000 - $999,999	2.00%	2.04%	1.75%
$1,000,000 - $3,999,999	0.00%	0.00%	1.00%
$4,000,000 - $9,999,999	0.00%	0.00%	0.50%
$10,000,000 or more	0.00%	0.00%	0.25%

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

Reductions and Waivers of Sales Charges for A Class

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

You and your immediate family (which includes your spouse or domestic partner and children, step-children, parents or step-parents of you, your spouse or domestic partner) may combine investments in any share class of any American Century Investments fund (excluding certain assets in money market accounts, but including, beginning January 1, 2011, account assets invested in Qualified Tuition Programs under Section 529) to reduce your A Class sales charge in the following ways:

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

• Certain trust accounts

• Solely controlled business accounts

• Single-participant retirement plans

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

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

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

Rights of Accumulation. You may take into account the current value of your existing holdings, less any commissionable shares in the money market funds, in any share class of any American Century Investments fund to qualify for a reduced A Class sales charge.

11

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

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

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

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

• Current officers, directors and employees of American Century Investments

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

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

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

C Class

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

American Century Investments generally limits purchases of C Class shares to investors whose aggregate investments in American Century Investments funds are less than $1,000,000. However, it is your responsibility to inform your financial intermediary and/or American Century Investments at the time of purchase of any accounts to be aggregated, including investments in any share class of any American Century Investments fund (excluding certain assets in money market accounts, but including, beginning January 1, 2011, account assets invested in Qualified Tuition Programs under Section 529) in accounts held by you and your immediate family members (which includes your spouse or domestic partner and children, step-children, parents or step-parents of you, your spouse or domestic partner). Once you reach this limit, you should work with your financial intermediary to determine what share class is most appropriate for additional purchases.

Calculation of Contingent Deferred Sales Charge (CDSC)

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

12

CDSC Waivers

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

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

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

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

• required minimum distributions from retirement accounts upon reaching age 70½

• tax-free returns of excess contributions to IRAs

• redemptions due to death or post-purchase disability

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

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

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

Reinstatement Privilege

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

Employer-Sponsored Retirement Plans

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

Exchanging Shares

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

• The exchange is for a minimum of $100

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

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

Some shares are subject to a redemption fee if they are exchanged in this manner (see Redemptions under Additional Policies Affecting Your Investment).

13

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.

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

14

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 (other than Institutional and R6 Classes)

Unless otherwise specified below, the minimum initial investment amount to open an account is $2,500. 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 (CESA)	$2,0001
Employer-sponsored retirement plans2	No minimum

¹  The minimum initial investment for shareholders investing through financial intermediaries is $250. Financial intermediaries may have different minimums for their clients.

²  For this purpose, employer-sponsored retirement plans do not include SEP IRAs, SIMPLE IRAs or SARSEPs.

Subsequent Purchases

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

Eligibility for Institutional Class Shares

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

Minimum Initial Investment Amounts (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, or your financial intermediary if you invest through an omnibus account, have an aggregate investment in our family of funds of $10 million or more ($5 million for endowments and foundations), or in other situations as determined by American Century Investments. 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. 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, in order to be eligible to purchase Institutional Class shares.

Eligibility for R6 Class Shares

The fund’s R6 Class shares are generally available only through employer-sponsored retirement plans where a financial intermediary provides retirement recordkeeping services to plan participants. To be eligible, plan level or omnibus accounts must be held on the books of the fund. R6 Class shares also are available to funds of funds advised by American Century and unaffiliated funds of funds sold primarily to the employer-sponsored retirement plan market.

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

15

Minimum Initial Investment Amounts (R6 Class)

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

Redemptions

If you redeem Investor, Institutional, R and R6 Class shares within 60 days of purchase, you may pay a redemption fee as described in the section below. If you sell your C or, in certain cases, A Class shares, you may pay a sales charge, depending on how long you have held your shares, as described above. Your redemption proceeds will be calculated using the net asset value (NAV) next determined after we receive your transaction request in good order.

However, we reserve the right to delay delivery of redemption proceeds 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. 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.

In addition, we reserve the right to honor certain redemptions with securities, rather than cash, as described in the next section.

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. The portfolio managers would select these securities from the fund’s portfolio.

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.

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.

Redemption of Shares in Accounts Below Minimum

If your account balance falls below the minimum initial investment amount for any reason, 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. Shares redeemed in this manner may be subject to a redemption fee if held less than a specified number of days (see Redemptions under Additional Policies Affecting Your Investment). Please note that shares redeemed in this manner may be subject to a sales charge if held less than the applicable time period. You also may incur tax liability as a result of the redemption. For Institutional Class shares, we reserve the right to convert your shares to Investor Class shares of the same fund. The Investor Class shares have a unified management fee that is 0.20 percentage points higher than the Institutional Class.

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.

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

16

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 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, imposing redemption fees on certain funds, and using fair value pricing when current market prices are not readily available. As a heightened measure for the fund, the board has approved the imposition of a redemption fee for shares held less than a specified number of days. See Redemption Fee under Additional Policies Affecting Your Investment. 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.

17

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 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, 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. 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.

18

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.

Thenet asset value, or NAV, of each class of the fund is the current value of the fund’s assets attributable to the class, minus any liabilities, divided by the number of shares of the class outstanding.

The fund values portfolio securities for which market quotations are readily available at their market price. As a general rule, equity securities listed on a U.S. exchange are valued at the last current reported sale price as of the time of valuation. Portfolio securities primarily traded on foreign securities exchanges are generally valued at the preceding closing values of such securities on the foreign exchange where primarily traded or at the time the fund’s NAV is determined, if that is earlier. That value is then converted to U.S. dollars at the prevailing foreign exchange rate. Securities listed on the NASDAQ National Market System (Nasdaq) are valued at the Nasdaq Official Closing Price (NOCP), as determined by Nasdaq, or lacking an NOCP, at the last current reported sale price as of the time of valuation. Securities that are neither listed on a securities exchange or traded over the counter may be priced using the mean of the bid and asked prices obtained from an independent broker who is an established market maker in the security. The fund may use third party pricing services to assist in the determination of market value.

If the fund determines that the market price for a portfolio security is not readily available or that the valuation methods mentioned above do not reflect the security’s fair value, such security is valued as determined in good faith by the fund’s board or its designee, in accordance with procedures adopted by the fund’s board. Circumstances that may cause the fund to use alternate procedures to value a security include, but are not limited to: 

• if, after the close of the foreign exchange on which a portfolio security is principally traded, but before the close of the NYSE, an event occurs that may materially affect the value of the security;

• a debt security has been declared in default; or

• trading in a security has been halted during the trading day.

If such circumstances occur, the fund 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 procedures adopted by the fund’s board.

The effect of using fair value determinations is that the fund’s NAV will be based, to some degree, on security valuations that the board or its designee believes are fair rather than being solely determined by the market.

With respect to any portion of the fund’s assets that are invested in one or more open-end management investment companies that are registered with the SEC (known as registered investment companies), the fund’s NAV will be calculated based upon the NAVs of such registered investment companies. These registered investment companies are required by law to explain the circumstances under which they will use fair value pricing and the effects of using fair value pricing in their prospectuses.

Securities and other assets quoted in foreign currencies are valued in U.S. dollars based on the prevailing exchange rates on that day.

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.

19

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. The fund may make more frequent distributions, if necessary, to comply with Internal Revenue Code provisions.

Capital gainsare increases in the values of capital assets, such as stock, 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.

20

Taxes

Some of the tax consequences of owning shares of the fund will vary depending on whether you own them through a taxable or tax-deferred account. Distributions by the 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 incomeis a dividend received by a fund from the stock of a domestic or qualifying foreign corporation, provided that the fund has held the stock for a required holding period.

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 a 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.

21

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.

22

Multiple Class Information

The fund offers multiple classes of shares. The classes have different fees, expenses and/or minimum investment requirements. The difference in the fee structures between the classes is the result of their separate arrangements for shareholder and distribution services. It is not the result of any difference in advisory or custodial fees or other expenses related to the management of the fund’s assets, which do not vary by class. The Institutional Class and R6 Class shareholders do not require the same level of shareholder and administrative services from the advisor as shareholders of the other classes. In addition, American Century does not pay any service, distribution or administrative fees to financial intermediaries for R6 Class shares. As a result, the advisor is able to charge these classes lower unified management fees. 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; (d) each class may have different exchange privileges; and (e) the Institutional Class may provide for conversion from that class into shares of the Investor Class of the same fund.

Service, Distribution and Administrative Fees

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

Certain financial intermediaries perform recordkeeping and administrative services for their clients that would otherwise be performed by American Century Investments’ transfer agent. In some circumstances, the advisor will pay such service providers a fee for performing those services. Also, the advisor and the 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 sponsor seminars and conferences designed to educate intermediaries about the fund and may cover the expenses associated with attendance at such meetings, including travel costs. 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 the available assets of the advisor and distributor, and not 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 service, distribution or administrative fees to financial intermediaries on R6 Class shares.

Example

The example below is intended to help you compare the costs of investing in the fund with the costs of investing in other mutual funds. The example assumes that you invest $10,000 in the fund for the time periods indicated and then redeem all of your shares at the end of those periods and that you earn a 5% return each year. The example also assumes that the fund’s operating expenses remain the same, except that it reflects the rate and duration of any fee waivers noted in the table above. Although your actual costs may be higher or lower, based on these assumptions your costs would be:

	1 year	3 years
Investor Class	$154	$478
Institutional Class	$134	$416
A Class	$744	$1,098
C Class	$255	$783
R Class	$204	$632
R6 Class	$118	$369

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. Because the fund is new, the fund’s portfolio turnover rate is not available.

Principal Investment Strategies

The fund will invest at least 80% of its net assets in securities issued by small cap companies. The portfolio managers consider small cap companies to include companies with market capitalizations not greater than that of the largest company on the MSCI ACWI Small Cap Index at the time of investment.

The fund invests in countries world-wide, including the United States, foreign developed countries and emerging markets. Under normal market conditions, the fund will invest at least 40% (unless the portfolio managers deem market conditions unfavorable, in which case the fund would invest at least 30%) of its assets in securities of issuers located outside of the United States. The fund will allocate its assets among at least three different countries (one of which may be the U.S.).

The portfolio managers look for stocks of companies they believe will increase in value over time, using an investment strategy developed by the fund’s investment advisor. In implementing this strategy, the portfolio managers make their investment decisions based primarily on their analysis of individual companies, rather than on economic forecasts. Management of the fund is based on the belief that, over the long term, stock price movements follow growth in earnings, revenues and/or cash flow. The portfolio managers use a variety of analytical research tools and techniques to identify the stocks of companies that meet their investment criteria. Under normal market conditions, the fund’s portfolio will primarily consist of securities of companies whose earnings or revenues are not only growing, but growing at an accelerating pace.

The fund may engage in active and frequent trading of portfolio securities to achieve its principal investment strategies. This may cause higher transaction costs and may affect performance. It may also result in the realization and distribution of capital gains.

Principal Risks 

• Foreign Risk — The fund invests in foreign securities, which are generally riskier than U.S. securities. As a result, the fund is subject to foreign risk, meaning that political events (such as civil unrest, national elections and imposition of exchange controls), social and economic events (such as labor strikes and rising inflation), and natural disasters 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.

• Small-Cap Stock Risk — The smaller companies in which the fund invests may be more volatile and subject to more risk than larger companies. Smaller companies may have limited financial resources, product lines, markets and have less publicly available information. In addition, securities of smaller companies may trade less frequently and in more limited volumes than securities of larger companies, which could lead to higher transaction costs. Smaller companies also may be more sensitive to changing economic conditions. Additionally, investing in securities of smaller foreign companies may present compounded risks to the typical risks of investing in foreign securities or small companies alone.

• Currency Risk — Because the fund generally invests in securities denominated in foreign currencies, the fund is subject to currency risk, meaning that the fund could experience gains or losses based solely on changes in the exchange rate between foreign currencies and the U.S. dollar.

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

• Growth Stocks — Investments in growth stocks may be more volatile than other stocks and the overall stock market. These stocks are typically priced higher than other stocks because of their growth potential, which may or may not be realized.

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

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

• Principal Loss — 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.

Purchase and Sale of Fund Shares

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

Unless otherwise specified below, the minimum initial investment amount to open an account is $10,000 ($2,000 for Coverdell Education Savings Accounts). Investors opening accounts through financial intermediaries may open an account with $250 for all classes except Institutional Class and R6 Class, but the financial intermediaries may require their clients to meet different investment minimums. The minimum may be waived for broker-dealer sponsored wrap program accounts, fee based accounts, and accounts through bank/trust and wealth management advisory organizations.

The minimum initial investment amount for Institutional Class is generally $5 million ($3 million for endowments and foundations), but the minimum may be waived if you, or your financial intermediary if you invest through an omnibus account, have an aggregate investment in the American Century family of funds of $10 million or more.

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

For all share classes, there is no minimum initial investment amount for certain employer-sponsored retirement plans, however, financial intermediaries or plan recordkeepers may require plans to meet different minimums. For purposes of fund minimums, employer-sponsored retirement plans do not include SEP IRAs, SIMPLE IRAs or SARSEPs.

There is a $50 minimum for subsequent purchases, except that there is no subsequent purchase minimum for financial intermediaries or employer-sponsored retirement plans.

Tax Information

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

Payments to Broker-Dealers and Other Financial Intermediaries

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

Objectives, Strategies and Risks

What is the fund’s investment objective?

The fund seeks capital growth. The fund’s investment objective is a non-fundamental policy and may be changed by the Board of Directors without shareholder approval upon 60 days’ notice to shareholders.

What are the fund’s principal investment strategies?

The fund will invest at least 80% of its net assets in securities issued by small cap companies. The portfolio managers consider small cap companies to include companies with market capitalizations not greater than the largest company in the MSCI ACWI Small Cap Index at the time of investment. Though market capitalization will change from time to time, as of [January 1, 2016], the market capitalization of the largest company on the MSCI ACWI Small Cap Index was [_________].

The fund invests in countries world-wide, including the United States, foreign developed countries and emerging markets. Under normal market conditions, the fund will invest at least 40% (unless the portfolio managers deem market conditions unfavorable, in which case the fund would invest at least 30%) of its assets in securities of issuers located outside of the United States. The fund will allocate its assets among at least three different countries (one of which may be the U.S.).

The fund considers a security to be an emerging markets security if its issuer is located outside the following developed countries list, which is subject to change: Australia, Austria, Belgium, Bermuda, Canada, Denmark, Finland, France, Germany, Hong Kong, Ireland, Israel, Italy, Japan, the Netherlands, New Zealand, Norway, Portugal, Singapore, Spain, Sweden, Switzerland, the United Kingdom and the United States.

In determining where a company is located, the portfolio managers will consider various factors, including where the company is headquartered, where the company’s principal operations are located, where the company’s revenues are derived, where the principal trading market is located and the country in which the company was legally organized. The weight given to each of these factors will vary depending on the circumstances in a given case.

The portfolio managers look for stocks of companies they believe will increase in value over time, using an investment strategy developed by the fund’s investment advisor. In implementing this strategy, the portfolio managers use a bottom-up approach to stock selection. This means that the managers make their investment decisions based primarily on their analysis of individual companies, rather than on broad economic forecasts. Management of the fund is based on the belief that, over the long term, stock price movements follow growth in earnings, revenues and/or cash flow.

Using a variety of analytical research tools, the portfolio managers track financial information for individual companies to identify and evaluate trends in earnings, revenues and other business fundamentals. Under normal market conditions, the fund’s portfolio will primarily consist of securities of companies whose earnings or revenues are not only growing, but growing at an accelerating pace. This includes companies whose growth rates, although still negative, are less negative than prior periods, and companies whose growth rates are expected to accelerate. Other analytical techniques help identify additional signs of business improvement, such as increasing cash flows, or other indications of the relative strength of a company’s business. These techniques help the portfolio managers buy or hold the stocks of companies they believe have favorable growth prospects and sell the stocks of companies whose characteristics no longer meet their criteria.

In addition to locating strong companies with earnings, revenue and/or cash flow growth, the portfolio managers believe that it is important to diversify the fund’s holdings across different countries and geographical regions in an effort to manage the risks of an international portfolio. For this reason, the portfolio managers also consider the prospects for relative economic growth among countries or regions, economic and political conditions, expected inflation rates, currency exchange fluctuations and tax considerations when making investments.

The portfolio managers do not attempt to time the market. Instead, under normal market conditions, they intend to keep the fund essentially fully invested in stocks regardless of the movement of stock prices generally. However, the fund can purchase other types of securities as well, such as forward currency exchange contracts, notes, bonds and other debt securities of companies, and obligations of domestic or foreign governments and their agencies.

Futures contracts, a type of derivative instrument, can help the fund’s cash assets remain liquid while performing more like stocks. The fund has a policy governing futures contracts and similar derivative instruments to help manage the risk of these types of investments. A complete description of the derivatives policy is included in the statement of additional information.

In the event of exceptional market or economic conditions, the fund may, as a temporary defensive measure, invest all or a substantial portion of its assets in cash or high-quality, short-term debt securities, denominated in U.S. dollars or another currency. To the extent the fund assumes a defensive position, however, it will not be pursuing its objective of capital growth.

When determining the size of a company, the portfolio managers will consider, among other factors, the capitalization of the company and the amount of revenues, as well as other information they obtain about the company.

5

The fund may engage in active and frequent trading of portfolio securities to achieve its principal investment strategies. A higher portfolio turnover rate may indicate higher transaction costs and may affect the fund’s performance. Higher portfolio turnover also may result in the realization and distribution of capital gains, including short-term capital gains.

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?

Investing in foreign securities has certain unique risks that make it generally riskier than investing in U.S. securities. These risks include increased exposure to political, social and economic events in world markets; limited availability of public information about a company; less-developed trading markets and regulatory practices; and a lack of uniform financial reporting practices compared to those that apply in the United States. Securities of foreign issuers may be less liquid, more volatile and harder to value than U.S. securities. The smaller companies in which the fund invests may be more volatile and subject to more risk than larger companies. Smaller companies may have limited financial resources, product lines, markets and have less publicly available information. In addition, securities of smaller companies may trade less frequently and in more limited volumes than securities of larger companies, which could lead to higher transaction costs. Smaller companies also may be more sensitive to changing economic conditions. Additionally, investing in securities of smaller foreign companies may present compounded risks to the typical risks of investing in foreign securities or small companies alone.

In addition, investments in foreign countries are subject to currency risk, meaning that because the fund’s investments are generally denominated in foreign currencies, the fund could experience gains or losses based solely on changes in the exchange rate between foreign currencies and the U.S. dollar.

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

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 manager’s assessment 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 market.

Market performance tends to be cyclical, and, in various cycles, certain investment styles may fall in and out of favor. If at any time the market is not favoring the fund’s growth 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.

The value of a 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.

The fund may need to sell securities at times it would not otherwise do so in order to meet shareholder redemption requests. The 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 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. Although the advisor seeks to minimize the impact of such transactions where possible, the fund’s performance may be adversely affected.

The portfolio managers may buy a large amount of a company’s stock quickly, and may dispose of it quickly if the company’s earnings or revenues decline. While the managers believe this strategy provides substantial appreciation potential over the long term, in the short term it can create a significant amount of share price volatility. This volatility can be greater than that of the average stock fund.

The fund’s performance also may be affected by investments in initial public offerings (IPOs). The impact of IPOs on a fund’s performance depends on the strength of the IPO market and the size of the fund. IPOs may have less impact on a fund’s performance as its assets grow.

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.

Management

Who manages the fund?

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

The Board of Directors

The Board of Directors 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 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 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 mutual funds since 1958 and is headquartered at 4500 Main Street, Kansas City, Missouri 64111.

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 fund, the advisor receives a unified management fee based on a percentage of the daily net assets of each class of shares of the fund. The amount of the fee is calculated daily and paid monthly in arrears. Out of that fee, the advisor pays all expenses of managing and operating the fund except brokerage expenses, taxes, interest, fees and expenses of the independent directors (including legal counsel fees), extraordinary expenses, and expenses incurred in connection with the provision of shareholder services and distribution services under a plan adopted pursuant to Rule 12b-1 under the Investment Company Act of 1940. For all classes other than the R6 Class, the advisor may pay unaffiliated third parties who provide recordkeeping and administrative services that would otherwise be performed by an affiliate of the advisor.

The fund will pay the advisor a unified management fee of 1.50% for Investor, A, C and R Class, a unified management fee of 1.30% for Institutional Class and a unified management fee of 1.15% for R6 Class.

A discussion regarding the basis for the Board of Directors’ approval of the fund’s investment advisory agreement with the advisor will be available in the fund’s annual report to shareholders dated November 30, 2016.

The Fund Management Team

The advisor uses teams of portfolio managers and analysts to manage funds. The teams meet regularly to review portfolio holdings and discuss 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.

The portfolio managers on the investment team who are jointly and primarily responsible for the day-to-day management of the fund are identified below.

Trevor Gurwich

Mr. Gurwich, Vice President and Senior Portfolio Manager, rejoined the team that manages the fund in 2005. He previously was a member of the team from 2001 until 2002. He joined American Century Investments in 1998 and became a portfolio manager in 2001. He has a bachelor’s degree in international relations from the University of Pennsylvania, a bachelor’s degree in economics from The Wharton School at the University of Pennsylvania and an MBA in finance and investment management from Columbia University.

Federico Laffan

Mr. Laffan, Vice President and Portfolio Manager, rejoined the team that manages the fund in 2014. He previously was a member of the team from 2001 until 2008, including as a portfolio manager from 2004 to 2008. He rejoined American Century Investments in 2011 as a senior investment analyst and became a portfolio manager in 2014. Prior to rejoining American Century Investments, he was an investment manager for Ranger International from 2010 to 2011. He has a bachelor’s degree in international studies from the University of Texas and a master’s degree in finance from the London Business School.

The statement of additional information provides additional information about the accounts managed by the portfolio managers, the structure of their compensation, and their ownership of fund securities.

Fundamental Investment Policies

Fundamental investment policies contained in the statement of additional information may not be changed without shareholder approval. The Board of Directors and/or the advisor may change any other policies or investment strategies described in this prospectus or otherwise used in the operation of the fund, including the fund’s investment objective, at any time.

Investing Through a Financial Intermediary

The funds 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.

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

Investor Class

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

Institutional Class

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

A Class

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

C Class

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

R Class

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

R6 Class

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

10

Calculation of Sales Charges

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

A Class

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

Purchase Amount	Sales Charge as a % of Offering Price	Sales Charge as a % of Net Amount Invested	Dealer Commission as a % of Offering Price
Less than $50,000	5.75%	6.10%	5.00%
$50,000 - $99,999	4.75%	4.99%	4.00%
$100,000 - $249,999	3.75%	3.90%	3.25%
$250,000 - $499,999	2.50%	2.56%	2.00%
$500,000 - $999,999	2.00%	2.04%	1.75%
$1,000,000 - $3,999,999	0.00%	0.00%	1.00%
$4,000,000 - $9,999,999	0.00%	0.00%	0.50%
$10,000,000 or more	0.00%	0.00%	0.25%

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

Reductions and Waivers of Sales Charges for A Class

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

You and your immediate family (which includes your spouse or domestic partner and children, step-children, parents or step-parents of you, your spouse or domestic partner) may combine investments in any share class of any American Century Investments fund (excluding certain assets in money market accounts, but including, beginning January 1, 2011, account assets invested in Qualified Tuition Programs under Section 529) to reduce your A Class sales charge in the following ways:

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

• Certain trust accounts

• Solely controlled business accounts

• Single-participant retirement plans

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

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

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

Rights of Accumulation. You may take into account the current value of your existing holdings, less any commissionable shares in the money market funds, in any share class of any American Century Investments fund to qualify for a reduced A Class sales charge.

11

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

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

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

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

• Current officers, directors and employees of American Century Investments

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

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

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

C Class

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

American Century Investments generally limits purchases of C Class shares to investors whose aggregate investments in American Century Investments funds are less than $1,000,000. However, it is your responsibility to inform your financial intermediary and/or American Century Investments at the time of purchase of any accounts to be aggregated, including investments in any share class of any American Century Investments fund (excluding certain assets in money market accounts, but including, beginning January 1, 2011, account assets invested in Qualified Tuition Programs under Section 529) in accounts held by you and your immediate family members (which includes your spouse or domestic partner and children, step-children, parents or step-parents of you, your spouse or domestic partner). Once you reach this limit, you should work with your financial intermediary to determine what share class is most appropriate for additional purchases.

Calculation of Contingent Deferred Sales Charge (CDSC)

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

12

CDSC Waivers 

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

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

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

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

• required minimum distributions from retirement accounts upon reaching age 70½

• tax-free returns of excess contributions to IRAs

• redemptions due to death or post-purchase disability

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

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

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

Reinstatement Privilege 

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

Employer-Sponsored Retirement Plans

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

Exchanging Shares

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

• The exchange is for a minimum of $100

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

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

Some shares are subject to a redemption fee if they are exchanged in this manner (see Redemptions under Additional Policies Affecting Your Investment).

13

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.

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 (other than Institutional and R6 Classes)

Unless otherwise specified below, the minimum initial investment amount to open an account is $2,500. 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 (CESA)	$2,0001
Employer-sponsored retirement plans2	No minimum

¹  The minimum initial investment for shareholders investing through financial intermediaries is $250. Financial intermediaries may have different minimums for their clients.

²  For this purpose, employer-sponsored retirement plans do not include SEP IRAs, SIMPLE IRAs or SARSEPs. 

Subsequent Purchases

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

Eligibility for Institutional Class Shares

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

Minimum Initial Investment Amounts (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, or your financial intermediary if you invest through an omnibus account, have an aggregate investment in our family of funds of $10 million or more ($5 million for endowments and foundations), or in other situations as determined by American Century Investments. 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. 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, in order to be eligible to purchase Institutional Class shares.

15

Eligibility for R6 Class Shares

The fund’s R6 Class shares are generally available only through employer-sponsored retirement plans where a financial intermediary provides retirement recordkeeping services to plan participants. To be eligible, plan level or omnibus accounts must be held on the books of the fund. R6 Class shares also are available to funds of funds advised by American Century and unaffiliated funds of funds sold primarily to the employer-sponsored retirement plan market.

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

Minimum Initial Investment Amounts (R6 Class)

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

Redemptions

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

However, we reserve the right to delay delivery of redemption proceeds 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. 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.

In addition, we reserve the right to honor certain redemptions with securities, rather than cash, as described in the next section.

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. The portfolio managers would select these securities from the fund’s portfolio.

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.

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.

Redemption of Shares in Accounts Below Minimum

If your account balance falls below the minimum initial investment amount for any reason, 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. Shares redeemed in this manner may be subject to a redemption fee, if held less than a specified number of days (see Redemptions under Additional Policies Affecting Your Investment). Please note that shares redeemed in this manner may be subject to a sales charge if held less than the applicable time period. You also may incur tax liability as a result of the redemption. For Institutional Class shares, we reserve the right to convert your shares to Investor Class shares of the same fund. The Investor Class shares have a unified management fee that is 0.20 percentage points higher than the Institutional Class.

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.

16

We reserve the right to require a signature guarantee for other transactions, or we may employ other security measures, such as signature comparison, 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 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, imposing redemption fees on certain funds, and using fair value pricing when current market prices are not readily available. As a heightened measure for the fund, the board has approved the imposition of a redemption fee for shares held less than a specified number of days. See Redemption Fee under Additional Policies Affecting Your Investment. 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.

17

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, 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. 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.

18

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 the fund is the current value of the fund’s assets attributable to the class, minus any liabilities, divided by the number of shares of the class outstanding.

The fund values portfolio securities for which market quotations are readily available at their market price. As a general rule, equity securities listed on a U.S. exchange are valued at the last current reported sale price as of the time of valuation. Portfolio securities primarily traded on foreign securities exchanges are generally valued at the preceding closing values of such securities on the foreign exchange where primarily traded or at the time the fund’s NAV is determined, if that is earlier. That value is then converted to U.S. dollars at the prevailing foreign exchange rate. Securities listed on the NASDAQ National Market System (Nasdaq) are valued at the Nasdaq Official Closing Price (NOCP), as determined by Nasdaq, or lacking an NOCP, at the last current reported sale price as of the time of valuation. Securities that are neither listed on a securities exchange or traded over the counter may be priced using the mean of the bid and asked prices obtained from an independent broker who is an established market maker in the security. The fund may use third party pricing services to assist in the determination of market value.

If the fund determines that the market price for a portfolio security is not readily available or that the valuation methods mentioned above do not reflect the security’s fair value, such security is valued as determined in good faith by the fund’s board or its designee, in accordance with procedures adopted by the fund’s board. Circumstances that may cause the fund to use alternate procedures to value a security include, but are not limited to:

• if, after the close of the foreign exchange on which a portfolio security is principally traded, but before the close of the NYSE, an event occurs that may materially affect the value of the security;

• a debt security has been declared in default; or

• trading in a security has been halted during the trading day.

If such circumstances occur, the fund 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 procedures adopted by the fund’s board.

The effect of using fair value determinations is that the fund’s NAV will be based, to some degree, on security valuations that the board or its designee believes are fair rather than being solely determined by the market.

With respect to any portion of the fund’s assets that are invested in one or more open-end management investment companies that are registered with the SEC (known as registered investment companies), the fund’s NAV will be calculated based upon the NAVs of such registered investment companies. These registered investment companies are required by law to explain the circumstances under which they will use fair value pricing and the effects of using fair value pricing in their prospectuses.

Securities and other assets quoted in foreign currencies are valued in U.S. dollars based on the prevailing exchange rates on that day.

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.

19

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 investment securities. The fund generally expects to pay distributions from net income and capital gains, if any, once a year. 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 stock, 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.

20

Taxes

Some of the tax consequences of owning shares of the fund will vary depending on whether you own them through a taxable or tax-deferred account. Distributions by the 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 a fund from the stock of a domestic or qualifying foreign corporation, provided that the fund has held the stock for a required holding period.

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 a 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.

21

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.

22

Multiple Class Information

The fund offers multiple classes of shares. The classes have different fees, expenses and/or minimum investment requirements. The difference in the fee structures between the classes is the result of their separate arrangements for shareholder and distribution services. It is not the result of any difference in advisory or custodial fees or other expenses related to the management of the fund’s assets, which do not vary by class. The Institutional Class and R6 Class shareholders do not require the same level of shareholder and administrative services from the advisor as shareholders of the other classes. In addition, American Century does not pay any service, distribution or administrative fees to financial intermediaries for R6 Class shares. As a result, the advisor is able to charge these classes lower unified management fees. 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; (d) each class may have different exchange privileges; and (e) the Institutional Class may provide for conversion from that class into shares of the Investor Class of the same fund.

Service, Distribution and Administrative Fees

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

Certain financial intermediaries perform recordkeeping and administrative services for their clients that would otherwise be performed by American Century Investments’ transfer agent. In some circumstances, the advisor will pay such service providers a fee for performing those services. Also, the advisor and the 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 sponsor seminars and conferences designed to educate intermediaries about the fund and may cover the expenses associated with attendance at such meetings, including travel costs. 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 the available assets of the advisor and distributor, and not 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 service, distribution or administrative fees to financial intermediaries on R6 Class shares.

The Funds’ History

American Century World Mutual Funds, Inc., is a registered open-end management investment company that was organized in 1990 as a Maryland corporation under the name Twentieth Century World Investors, Inc. In January 1997, it changed its name to American Century World Mutual Funds, Inc. Throughout this statement of additional information we refer to American Century World Mutual Funds, Inc. as the corporation.

For accounting and performance purposes, the International Value fund is the post-reorganization successor to the Mason Street International Equity fund. All references to fees and expenses paid by the International Value fund prior to April 1, 2006, are for the fiscal year ended March 31, and represent amounts paid by the Mason Street International Equity fund.

Each fund described in this statement of additional information is a separate series of the corporation and operates for many purposes as if it were an independent company. Each fund has its own investment objective, strategy, management team, assets, and tax identification and stock registration numbers.

Fund Investment Guidelines

This section explains the extent to which the funds’ advisor, American Century Investment Management, Inc. (ACIM), can use various investment vehicles and strategies in managing a fund’s assets. Descriptions of the investment techniques and risks associated with each appear in the section, Investment Strategies and Risks, which begins on page 4. In the case of the funds’ principal investment strategies, these descriptions elaborate upon discussions contained in the prospectuses.

The funds, other than Focused International Growth, are diversified as defined in the Investment Company Act of 1940 (the Investment Company Act). Diversified means that, with respect to 75% of its total assets, each fund will not invest more than 5% of its total assets in the securities of a single issuer or own more than 10% of the outstanding voting securities of a single issuer (other than U.S. government securities or securities of other investment companies).

Focused International Growth is nondiversified. Nondiversified means that a fund may invest a greater portion of its assets in a smaller number of securities than a diversified fund.

To meet federal tax requirements for qualification as a regulated investment company, each fund must limit its investments so that at the close of each quarter of its taxable year

(1) no more than 25% of its total assets are invested in the securities of a single issuer (other than the U.S. government or a regulated investment company), and

(2) with respect to at least 50% of its total assets, no more than 5% of its total assets are invested in the securities of a single issuer (other than the U.S. government or a regulated investment company) and it does not own more than 10% of the outstanding voting securities of a single issuer.

In general, within the restrictions outlined here and in the funds’ prospectuses, the portfolio managers have broad powers to decide how to invest fund assets, including the power to hold them uninvested.

Investments are varied according to what is judged advantageous under changing economic conditions. It is the advisor’s policy to retain maximum flexibility in management without restrictive provisions as to the proportion of one or another class of securities that may be held, subject to the investment restrictions described below. It is the advisor’s intention that each fund will generally consist of foreign (and U.S. in the case of Global Growth and Global Small Cap) equity and equity-equivalent securities. However, subject to the specific limitations applicable to a fund, the funds’ management teams may invest the assets of each fund in varying amounts in other instruments when such a course is deemed appropriate in order to pursue a fund’s investment objective. Unless otherwise noted, all investment restrictions described below and in each fund’s prospectus are measured at the time of the transaction in the security. If market action affecting fund securities (including, but not limited to, appreciation, depreciation or a credit rating event) causes a fund to exceed an investment restriction, the advisor is not required to take immediate action. Under normal market conditions, however, the advisor's policies and procedures indicate that the advisor will not make any purchases that will make the fund further outside the investment restriction.

So long as a sufficient number of acceptable securities are available, the portfolio managers intend to keep the funds fully invested, regardless of the movement of stock or bond prices generally. In most circumstances, each fund’s actual level of cash and cash equivalents will be less than 10%. The managers may use futures as a way to expose each fund’s cash assets to the market, while maintaining liquidity. The managers may not leverage a fund’s portfolio without appropriately segregating assets to cover such positions. See Derivative Instruments, page 6, Futures and Options, page 9 and Short-Term Securities, page 14.

Fund Investments and Risks

Investment Strategies and Risks

This section describes investment vehicles and techniques the portfolio managers can use in managing a fund’s assets. It also details the risks associated with each, because each investment vehicle and technique contributes to a fund’s overall risk profile.

Convertible Securities

A convertible security is a bond, debenture, note, preferred stock or other security that may be converted into or exchanged for a prescribed amount of common stock of the same or a different issuer within a particular time period at a specified price or formula. A convertible security entitles the holder to receive the interest paid or accrued on debt or the dividend paid on preferred stock until the convertible security matures or is redeemed, converted or exchanged. Before conversion or exchange, such securities ordinarily provide a stream of income with generally higher yields than common stocks of the same or similar issuers, but lower than the yield on non-convertible debt. Of course, there can be no assurance of current income because issuers of convertible securities may default on their obligations. In addition, there can be no assurance of capital appreciation because the value of the underlying common stock will fluctuate. Because of the conversion feature, the managers consider some convertible securities to be equity equivalents.

4

The price of a convertible security will normally fluctuate in some proportion to changes in the price of the underlying asset. A convertible security is subject to risks relating to the activities of the issuer and/or general market and economic conditions. The stream of income typically paid on a convertible security may tend to cushion the security against declines in the price of the underlying asset. However, the stream of income causes fluctuations based upon changes in interest rates and the credit quality of the issuer. In general, the value of a convertible security is a function of (1) its yield in comparison with yields of other securities of comparable maturity and quality that do not have a conversion privilege and (2) its worth, at market value, if converted or exchanged into the underlying common stock. The price of a convertible security often reflects such variations in the price of the underlying common stock in a way that a non-convertible security does not. At any given time, investment value generally depends upon such factors as the general level of interest rates, the yield of similar nonconvertible securities, the financial strength of the issuer and the seniority of the security in the issuer’s capital structure.

A convertible security may be subject to redemption at the option of the issuer at a predetermined price. If a convertible security held by a fund is called for redemption, the fund would be required to permit the issuer to redeem the security and convert it to underlying common stock or to cash, or would sell the convertible security to a third party, which may have an adverse effect on the fund. A convertible security may feature a put option that permits the holder of the convertible security to sell that security back to the issuer at a predetermined price. A fund generally invests in convertible securities for their favorable price characteristics and total return potential and normally would not exercise an option to convert unless the security is called or conversion is forced.

Counterparty Risk

A fund will be exposed to the credit risk of the counterparties with which, or the brokers, dealers and exchanges through which, it deals, whether it engaged in exchange traded or off-exchange transactions. If a fund’s futures commission merchant, (FCM) becomes bankrupt or insolvent, or otherwise defaults on its obligations to the fund, the fund may not receive all amounts owed to it in respect of its trading, despite the clearinghouse fully discharging all of its obligations. The Commodity Exchange Act requires an FCM to segregate all funds received from its customers with respect to regulated futures transactions from such FCM’s proprietary funds. If an FCM were not to do so to the full extent required by law, the assets of an account might not be fully protected in the event of the bankruptcy of an FCM. Furthermore, in the event of an FCM’s bankruptcy, a fund would be limited to recovering only a pro rata share of all available funds segregated on behalf of an FCM’s combined customer accounts, even though certain property specifically traceable to the fund (for example, U.S. Treasury bills deposited by the fund) was held by an FCM. FCM bankruptcies have occurred in which customers were unable to recover from the FCM’s estate the full amount of their funds on deposit with such FCM and owing to them. Such situations could arise due to various factors, or a combination of factors, including inadequate FCM capitalization, inadequate controls on customer trading and inadequate customer capital. In addition, in the event of the bankruptcy or insolvency of a clearinghouse, the fund might experience a loss of funds deposited through its FCM as margin with the clearinghouse, a loss of unrealized profits on its open positions, and the loss of funds owed to it as realized profits on closed positions. Such a bankruptcy or insolvency might also cause a substantial delay before the fund could obtain the return of funds owed to it by an FCM who was a member of such clearinghouse.

Because bi-lateral derivative transactions are traded between counterparties based on contractual relationships, a fund is subject to the risk that a counterparty will not perform its obligations under the related contracts. Although each fund intends to enter into transactions only with counterparties which the advisor believes to be creditworthy, there can be no assurance that a counterparty will not default and that the funds will not sustain a loss on a transaction as a result. In situations where a fund is required to post margin or other collateral with a counterparty, the counterparty may fail to segregate the collateral or may commingle the collateral with the counterparty’s own assets. As a result, in the event of the counterparty’s bankruptcy or insolvency, a fund’s collateral may be subject to the conflicting claims of the counterparty’s creditors, and a fund may be exposed to the risk of a court treating a fund as a general unsecured creditor of the counterparty, rather than as the owner of the collateral.

A fund is subject to the risk that issuers of the instruments in which it invests and trades may default on their obligations under those instruments, and that certain events may occur that have an immediate and significant adverse effect on the value of those instruments. There can be no assurance that an issuer of an instrument in which a fund invests will not default, or that an event that has an immediate and significant adverse effect on the value of an instrument will not occur, and that a fund will not sustain a loss on a transaction as a result.

Transactions entered into by a fund may be executed on various U.S. and non-U.S. exchanges, and may be cleared and settled through various clearinghouses, custodians, depositories and prime brokers throughout the world. Although a fund attempts to execute, clear and settle the transactions through entities the advisor believes to be sound, there can be no assurance that a failure by any such entity will not lead to a loss to a fund.

5

Cyber Security Risk

As the funds increasingly rely on technology and information systems to operate, they become susceptible to operational risks linked to security breaches in those information systems. Both calculated attacks and unintentional events can cause failures in the funds’ information systems. Cyber attacks can include acquiring unauthorized access to information systems, usually through hacking or the use of malicious software, for purposes of stealing assets or confidential information, corrupting data, or disrupting fund operations. Cyber attacks can also occur without direct access to information systems, for example by making network services unavailable to intended users. Cyber security failures by, or breaches of the information systems of, the advisor, distributors, broker-dealers, other service providers (including, but not limited to, index providers, fund accountants, custodians, transfer agents and administrators), or the issuers of securities the fund invests in may also cause disruptions and impact the funds’ business operations. Breaches in information security may result in financial losses, interference with the funds’ ability to calculate NAV, impediments to trading, inability of fund shareholders to transact business, violations of applicable privacy and other laws, regulatory fines, penalties, reputational damage, reimbursement or other compensation costs, or additional compliance costs. Additionally, the funds may incur substantial costs to prevent future cyber incidents. The funds have business continuity plans in the event of, and risk management systems to help prevent, such cyber attacks, but these plans and systems have limitations including the possibility that certain risks have not been identified. Moreover, the funds do not control the cyber security plans and systems of our service providers and other third party business partners. The funds and their shareholders could be negatively impacted as a result.

Debt Securities

The managers believe that equity securities ordinarily offer the greatest potential for capital appreciation. The funds may invest, however, in any security the managers believe has the potential for capital appreciation. When the managers believe that the total return potential of other securities equals or exceeds the potential return of equity securities, each fund (except Emerging Markets, Emerging Markets Small Cap, International Value, NT Emerging Markets and NT International Value, which are 20%) may invest up to 35% of its assets in such other securities. The other securities the funds may invest in are bonds, notes and debt securities of companies, and obligations of domestic or foreign governments and their agencies.

The funds may purchase sovereign debt instruments issued or guaranteed by foreign governments or their agencies, including debt of emerging market countries. Sovereign debt may be in the form of conventional securities or other types of debt instruments, such as loans or loan participations. Sovereign debt of emerging market countries may involve a high degree of risk and may present a risk of default or renegotiation or rescheduling of debt payments.

In the event of exceptional market or economic conditions, the funds may, as a temporary defensive measure, invest all or a substantial portion of their assets in cash or high-quality, short-term debt securities. To the extent a fund assumes a defensive position, it will not be pursuing its objective of capital growth. Global Growth, International Growth, Focused International Growth and NT International Growth will limit their purchases of debt securities to investment-grade obligations except convertible securities, which may be rated below investment grade. For long-term debt obligations, this includes securities that are rated Baa or better by Moody’s Investors Service, Inc. or BBB or better by Standard & Poor’s Corporation (S&P), or that are not rated but are considered by the managers to be of equivalent quality. According to Moody’s, bonds rated Baa are medium-grade and possess some speculative characteristics. A BBB rating by S&P indicates S&P’s belief that a security exhibits a satisfactory degree of safety and capacity for repayment, but is more vulnerable to adverse economic conditions or changing circumstances than is the case with higher-quality debt securities. See Explanation of Fixed-Income Securities Ratings,Appendix D.

Emerging Markets, Emerging Markets Small Cap, Global Small Cap, International Discovery, International Opportunities, International Value, NT Emerging Markets, NT International Small-Mid Cap and NT International Value have no credit quality or maturity restrictions with regard to the bonds, corporate debt securities and government obligations in which the funds may invest, although less than 35% (20% for Emerging Markets, Emerging Markets Small Cap, International Value, NT Emerging Markets and NT International Value) of each fund’s assets will be invested in below-investment-grade fixed income securities. See Explanation of Fixed-Income Securities Ratings,Appendix D. Debt securities, especially those of issuers in emerging market countries, may be of poor quality and speculative in nature. While these securities will be chosen primarily for their appreciation potential, a fund also may take the potential for income into account when selecting investments.

In addition to other factors that will affect its value, the value of a fund’s investments in fixed income securities will change as prevailing interest rates change. In general, the prices of such securities vary inversely with interest rates. As prevailing interest rates fall, the prices of bonds and other securities that trade on a yield basis rise. When prevailing interest rates rise, bond prices generally fall. These changes in value may, depending upon the particular amount and type of fixed-income securities holdings of a fund, impact the net asset value of that fund’s shares.

6

Derivative Instruments

To the extent permitted by its investment objectives and policies, each of the funds may invest in instruments that are commonly referred to as derivative instruments. Generally, a derivative instrument is a financial arrangement the value of which is based on, or derived from, a traditional security, asset, or market index. Examples of common derivative instruments include futures contracts, warrants, structured notes, credit default swaps, options contracts, swap transactions and forward currency contracts.

Certain derivative instruments are more accurately described as index/structured investments. Index/structured investments are derivative instruments whose value or performance is linked to other equity securities (such as depositary receipts), currencies, interest rates, indices or other financial indicators (reference indices). For example, Standard & Poor’s Depositary Receipts, also known as “SPDRS,” track the price performance and dividend yield of an S&P Index by providing a stake in the stocks that make up that index.

In addition, the funds may make foreign investments either directly in foreign securities or indirectly by purchasing derivative instruments known as depositary receipts, depositary shares or similar instruments (DRs) for foreign securities. DRs are securities that are listed on exchanges or quoted in over-the-counter markets in one country but represent shares of issuers domiciled in another country. The funds also may purchase securities of issuers in foreign markets, either on foreign securities exchanges, electronic trading networks or in over-the-counter markets.

Some derivative instruments, such as mortgage-related and other asset-backed securities, are in many respects like any other investment, although they may be more volatile or less liquid than more traditional debt securities.

There are many different types of derivative instruments and many different ways to use them. Futures and options are commonly used for traditional hedging purposes to attempt to protect a fund from exposure to changing interest rates, securities prices, or currency exchange rates and for cash management purposes as a low-cost method of gaining exposure to a particular securities market without investing directly in those securities.

The return on a derivative instrument may increase or decrease, depending upon changes in the reference index or instrument to which it relates. 

There are risks associated with investing in derivatives, including:

• the risk that the underlying security, interest rate, market index or other financial asset will not move in the direction the portfolio managers anticipate or that the value of the structured or derivative instrument will not move or react to changes in the underlying security, interest rate, market index or other financial asset as anticipated;

• the possibility that there may be no liquid secondary market, which may make it difficult or impossible to close out a position when desired;

• the risk that daily limits on price fluctuations and speculative position limits on exchanges on which a fund may conduct its transactions in derivative instruments may prevent profitable liquidation of positions, subjecting a fund to the potential of greater losses;

• the risk that adverse price movements in an instrument can result in a loss substantially greater than a fund’s initial investment;

• the risk that the counterparty will fail to perform its obligations; and

• the risk that a fund will be subject to higher volatility because some derivative instruments create leverage.

A fund may not invest in a derivative instrument if its credit, interest rate, liquidity, counterparty and other risks associated with ownership of the security are outside acceptable limits set forth in the fund’s prospectus. The funds’ Board of Directors has reviewed the advisor’s policy regarding investments in derivative instruments. That policy specifies factors that must be considered in connection with a purchase of derivative instruments. The policy also establishes a committee that must review certain proposed purchases before the purchases can be made. The advisor will report on fund activity in derivative instruments to the Board of Directors as necessary.

In addition to investing in common stocks, the funds may invest in other equity securities and equity equivalents, including securities that permit a fund to receive an equity interest in an issuer, the opportunity to acquire an equity interest in an issuer, or the opportunity to receive a return on its investment that permits the fund to benefit from the growth over time in the equity of an issuer. Examples of equity securities and equity equivalents include preferred stock, convertible preferred stock, convertible securities, stock futures contracts or stock index futures contracts. Equity equivalents also may include securities whose value or return is derived from the value or return of a different security.

Foreign Currency Transactions and Forward Exchange Contracts

A fund may conduct foreign currency transactions on a spot basis (i.e., cash) or forward basis (i.e., by entering into forward currency exchange contracts, currency options and futures transactions to purchase or sell foreign currencies). Although foreign exchange dealers generally do not charge a fee for such transactions, they do realize a profit based on the difference between the prices at which they are buying and selling various currencies.

Forward contracts are customized transactions that require a specific amount of a currency to be delivered at a specific exchange rate on a specific date or range of dates in the future. Forward contracts are generally traded in an interbank market directly between currency traders (usually larger commercial banks) and their customers. The parties to a forward contract may agree to offset or terminate the contract before its maturity, or may hold the contract to maturity and complete the contemplated currency exchange.

The following summarizes the principal currency management strategies involving forward contracts. A fund may also use swap agreements, indexed securities, and options and futures contracts relating to foreign currencies for the same purposes.

(1) Settlement Hedges or Transaction Hedges. When the portfolio managers wish to lock in the U.S. dollar price of a foreign currency denominated security when a fund is purchasing or selling the security, the fund may enter into a forward contract to do so. This type of currency transaction, often called a “settlement hedge” or “transaction hedge,” protects the fund against an adverse change in foreign currency values between the date a security is purchased or sold and the date on which payment is made or received (i.e., settled). Forward contracts to purchase or sell a foreign currency may also be used by a fund in anticipation of future purchases or sales of securities denominated in foreign currency, even if the specific investments have not yet been selected by the portfolio managers. This strategy is often referred to as “anticipatory hedging.”

(2) Position Hedges. When the portfolio managers believe that the currency of a particular foreign country may suffer substantial decline against the U.S. dollar, a fund may enter into a forward contract to sell foreign currency for a fixed U.S. dollar amount approximating the value of some or all of its portfolio securities either denominated in, or whose value is tied to, such foreign currency. This use of a forward contract is sometimes referred to as a “position hedge.” For example, if a fund owned securities denominated in Euro, it could enter into a forward contract to sell Euro in return for U.S. dollars to hedge against possible declines in the Euro’s value. This hedge would tend to offset both positive and negative currency fluctuations, but would not tend to offset changes in security values caused by other factors.

A fund could also hedge the position by entering into a forward contract to sell another currency expected to perform similarly to the currency in which the fund’s existing investments are denominated. This type of hedge, often called a “proxy hedge,” could offer advantages in terms of cost, yield or efficiency, but may not hedge currency exposure as effectively as a simple position hedge against U.S. dollars. This type of hedge may result in losses if the currency used to hedge does not perform similarly to the currency in which the hedged securities are denominated.

The precise matching of forward contracts in the amounts and values of securities involved generally would not be possible because the future values of such foreign currencies will change as a consequence of market movements in the values of those securities between the date the forward contract is entered into and the date it matures. Predicting short-term currency market movements is extremely difficult, and the successful execution of a short-term hedging strategy is highly uncertain. Normally, consideration of the prospect for currency parities will be incorporated into the long-term investment decisions made with respect to overall diversification strategies. However, the managers believe that it is important to have flexibility to enter into such forward contracts when they determine that a fund’s best interests may be served.

At the maturity of the forward contract, the fund may either sell the portfolio security and make delivery of the foreign currency, or it may retain the security and terminate the obligation to deliver the foreign currency by purchasing an “offsetting” forward contract with the same currency trader obligating the fund to purchase, on the same maturity date, the same amount of the foreign currency.

It is impossible to forecast with absolute precision the market value of portfolio securities at the expiration of the forward contract. Accordingly, it may be necessary for a fund to purchase additional foreign currency on the spot market (and bear the expense of such purchase) if the market value of the security is less than the amount of foreign currency the fund is obligated to deliver and if a decision is made to sell the security and make delivery of the foreign currency the fund is obligated to deliver.

(3) Shifting Currency Exposure. A fund may also enter into forward contracts to shift its investment exposure from one currency into another. This may include shifting exposure from U.S. dollars to foreign currency, or from one foreign currency to another foreign currency. This strategy tends to limit exposure to the currency sold, and increase exposure to the currency that is purchased, much as if a fund had sold a security denominated in one currency and purchased an equivalent security denominated in another currency. For example, if the portfolio managers believed that the U.S. dollar may suffer a substantial decline against the Euro, they could enter into a forward contract to purchase Euros for a fixed amount of U.S. dollars. This transaction would protect against losses resulting from a decline in the value of the U.S. dollar, but would cause the fund to assume the risk of fluctuations in the value of the Euro.

8

Successful use of currency management strategies will depend on the fund management team’s skill in analyzing currency values. Currency management strategies may substantially change a fund’s investment exposure to changes in currency rates and could result in losses to a fund if currencies do not perform as the portfolio managers anticipate. For example, if a currency’s value rose at a time when the portfolio manager hedged a fund by selling the currency in exchange for U.S. dollars, a fund would not participate in the currency’s appreciation. Similarly, if the portfolio managers increase a fund’s exposure to a currency and that currency’s value declines, a fund will sustain a loss. There is no assurance that the portfolio managers’ use of foreign currency management strategies will be advantageous to a fund or that they will hedge at appropriate times.

The fund will generally cover outstanding forward contracts by maintaining liquid portfolio securities denominated in, or whose value is tied to, the currency underlying the forward contract or the currency being hedged. To the extent that the fund is not able to cover its forward currency positions with underlying portfolio securities, the fund’s custodian will segregate cash or other liquid assets having a value equal to the aggregate amount of the fund’s commitments under forward contracts entered into with respect to position hedges, settlement hedges and anticipatory hedges.

Foreign Securities

Each fund invests in the securities of foreign issuers, including foreign governments, when these securities meet the fund’s standards of selection.

A description of the funds’ investment strategies regarding foreign securities is contained in the funds’ prospectuses. Investing in securities of foreign issuers generally involves greater risks than investing in the securities of domestic companies including:

Currency Risk. The value of the foreign investments held by the funds may be significantly affected by changes in currency exchange rates. The dollar value of a foreign security generally decreases when the value of the dollar rises against the foreign currency in which the security is denominated and tends to increase when the value of the dollar falls against such currency. In addition, the value of fund assets may be affected by losses and other expenses incurred in converting between various currencies in order to purchase and sell foreign securities, and by currency restrictions, exchange control regulation, currency devaluations and political developments.

Social, Political and Economic Risk. The economies of many of the countries in which the funds invest are not as developed as the economy of the United States and may be subject to significantly different forces. Political or social instability, expropriation, nationalization, or confiscatory taxation, and limitations on the removal of funds or other assets, could also adversely affect the value of investments. Further, the funds may find it difficult or be unable to enforce ownership rights, pursue legal remedies or obtain judgments in foreign courts.

Regulatory Risk. Foreign companies generally are not subject to the regulatory controls imposed on U.S. issuers and, in general, there is less publicly available information about foreign securities than is available about domestic securities. Many foreign companies are not subject to uniform accounting, auditing and financial reporting standards, practices and requirements comparable to those applicable to domestic companies and there may be less stringent investor protection and disclosure standards in some foreign markets. Income from foreign securities owned by the funds may be reduced by a withholding tax at the source, which would reduce dividend income payable to shareholders.

Market and Trading Risk. Brokerage commission rates in foreign countries, which are generally fixed rather than subject to negotiation as in the United States, are likely to be higher. The securities markets in many of the countries in which the funds invest will have substantially less trading volume than the principal U.S. markets. As a result, the securities of some companies in these countries may be less liquid, more volatile and harder to value than comparable U.S. securities. Furthermore, one securities broker may represent all or a significant part of the trading volume in a particular country, resulting in higher trading costs and decreased liquidity due to a lack of alternative trading partners. There is generally less government regulation and supervision of foreign stock exchanges, brokers and issuers, which may make it difficult to enforce contractual obligations. In addition, it may be more difficult in foreign countries to accurately determine appropriate brokerage commissions, taxes and other trading costs related to securities trades.

Clearance and Settlement Risk. Foreign securities markets also have different clearance and settlement procedures, and in certain markets there have been times when settlements have been unable to keep pace with the volume of securities transactions, making it difficult to conduct such transactions. Delays in clearance and settlement could result in temporary periods when assets of the funds are uninvested and no return is earned. The inability of the funds to make intended security purchases due to clearance and settlement problems could cause the funds to miss attractive investment opportunities. Inability to dispose of portfolio securities due to clearance and settlement problems could result either in losses to the funds due to subsequent declines in the value of the portfolio security or, if the fund has entered into a contract to sell the security, liability to the purchaser.

9

Ownership Risk. Evidence of securities ownership may be uncertain in many foreign countries. In many of these countries, the most notable of which is the Russian Federation, the ultimate evidence of securities ownership is the share register held by the issuing company or its registrar. While some companies may issue share certificates or provide extracts of the company’s share register, these are not negotiable instruments and are not effective evidence of securities ownership. In an ownership dispute, the company’s share register is controlling. As a result, there is a risk that a fund’s trade details could be incorrectly or fraudulently entered on the issuer’s share register at the time of the transaction, or that a fund’s ownership position could thereafter be altered or deleted entirely, resulting in a loss to the fund. While the funds intend to invest directly in Russian companies that utilize an independent registrar, there can be no assurance that such investments will not result in a loss to the funds.

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

As a result of the foregoing risks, these funds are 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 funds will pursue. An investment in the funds is not appropriate for individuals with limited investment resources or who are unable to tolerate fluctuations in the value of their investment.

Risk of Focusing Investment on Region or Country. Investing a significant portion of assets in one country or region makes a fund more dependent upon the political and economic circumstances of that particular country or region.

Eurozone Investment Risk. The recent global economic crisis brought several small economies in Europe to the brink of bankruptcy and many other economies into recession and weakened the banking and financial sector of many European countries. For example, the governments of Greece, Spain, Portugal and the Republic of Ireland have all recently experienced large public budget deficits, the effects of which are still unknown and may slow the overall recovery of the European economies from the recent global economic crisis. In addition, due to large public deficits, some European countries may be dependent on assistance from other European governments and institutions or agencies. Assistance may be dependent on a country’s implementation of reforms or reaching a certain level of performance. Failure to reach those objectives or an insufficient level of assistance could result in an economic downturn that could significantly affect the value of the fund’s European investments.

The Economic and Monetary Union of the European Union (EMU) is comprised of the European Union members that have adopted the euro currency. By adopting the euro as its currency, a member state relinquishes control of its own monetary policies. As a result, European countries are significantly affected by fiscal and monetary controls implemented by the EMU. The euro currency may not fully reflect the strengths and weaknesses of the various economies that comprise the EMU and Europe generally. One or more countries could depart from the EU, which could further weaken the EMU and, by extension, its remaining members.

Futures and Options

Each fund may enter into futures contracts, options or options on futures contracts. Futures contracts provide for the sale by one party and purchase by another party of a specific security at a specified future time and price. Generally, futures transactions will be used to:

• protect against a decline in market value of the fund’s securities (taking a short futures position), or

• protect against the risk of an increase in market value for securities in which the fund generally invests at a time when the fund is not fully-invested (taking a long futures position), or

• provide a temporary substitute for the purchase of an individual security that may be purchased in an orderly fashion.

Some futures and options strategies, such as selling futures, buying puts and writing calls, hedge a fund’s investments against price fluctuations. Other strategies, such as buying futures, writing puts and buying calls, tend to increase market exposure.

Although other techniques may be used to control a fund’s exposure to market fluctuations, the use of futures contracts may be a more effective means of hedging this exposure. While a fund pays brokerage commissions in connection with opening and closing out futures positions, these costs are lower than the transaction costs incurred in the purchase and sale of the underlying securities.

For example, the sale of a future by a fund means the fund becomes obligated to deliver the security (or securities, in the case of an index future) at a specified price on a specified date. The purchase of a future means the fund becomes obligated to buy the security (or securities) at a specified price on a specified date. The portfolio managers may engage in futures and options transactions, provided that the transactions are consistent with the fund’s investment objectives. Examples of indices that may be used include the Morgan Stanley Capital International (MSCI) Europe, Australasia, Far East (EAFE) Index, the S&P/Citigroup EMI Growth World ex-US Index, and the MSCI Emerging Markets Free Index. The managers also may engage in futures and options transactions based on specific securities. Futures contracts are traded on national futures exchanges. Futures exchanges and trading are regulated under the Commodity Exchange Act by the Commodity Futures Trading Commission (CFTC), a U.S. government agency.

10

Index futures contracts differ from traditional futures contracts in that when delivery takes place, no stocks or bonds change hands. Instead, these contracts settle in cash at the spot market value of the index. Although other types of futures contracts by their terms call for actual delivery or acceptance of the underlying securities, in most cases the contracts are closed out before the settlement date. A futures position may be closed by taking an opposite position in an identical contract (i.e., buying a contract that has previously been sold or selling a contract that has previously been bought).

Unlike when the fund purchases or sells a security, no price is paid or received by the fund upon the purchase or sale of the future. Initially, the fund will be required to deposit an amount of cash or securities equal to a varying specified percentage of the contract amount. This amount is known as initial margin. The margin deposit is intended to ensure completion of the contract (delivery or acceptance of the underlying security) if it is not terminated prior to the specified delivery date. A margin deposit does not constitute a margin transaction for purposes of the fund’s investment restrictions. Minimum initial margin requirements are established by the futures exchanges and may be revised.

In addition, brokers may establish margin deposit requirements that are higher than the exchange minimums. Cash held in the margin accounts generally is not income producing. However, coupon bearing securities, such as Treasury bills and bonds, held in margin accounts generally will earn income. Subsequent payments, to and from the broker, called variation margin, will be made on a daily basis as the price of the underlying security or index fluctuates, making the future more or less valuable, a process known as marking the contract to market. Changes in variation margin are recorded by the fund as unrealized gains or losses. At any time prior to expiration of the future, the fund may elect to close the position by taking an opposite position. A final determination of variation margin is then made; additional cash is required to be paid by or released to the fund and the fund realizes a loss or gain.

Risks Related to Futures and Options Transactions

Futures and options prices can be volatile, and trading in these markets involves certain risks. If the portfolio managers apply a hedge at an inappropriate time or judge interest rate or equity market trends incorrectly, futures and options strategies may lower a fund’s return.

A fund could suffer losses if it were unable to close out its position because of an illiquid secondary market. Futures contracts may be closed out only on an exchange that provides a secondary market for these contracts, and there is no assurance that a liquid secondary market will exist for any particular futures contract at any particular time. Consequently, it may not be possible to close a futures position when the portfolio managers consider it appropriate or desirable to do so. In the event of adverse price movements, a fund would be required to continue making daily cash payments to maintain its required margin. If the fund had insufficient cash, it might have to sell portfolio securities to meet daily margin requirements at a time when the portfolio managers would not otherwise elect to do so. In addition, a fund may be required to deliver or take delivery of instruments underlying futures contracts it holds. The portfolio managers will seek to minimize these risks by limiting the futures contracts entered into on behalf of the funds to those traded on national futures exchanges and for which there appears to be a liquid secondary market.

A fund could suffer losses if the prices of its futures and options positions were poorly correlated with its other investments, or if securities underlying futures contracts purchased by a fund had different maturities than those of the portfolio securities being hedged. Such imperfect correlation may give rise to circumstances in which a fund loses money on a futures contract at the same time that it experiences a decline in the value of its hedged portfolio securities. A fund also could lose margin payments it has deposited with a margin broker, if, for example, the broker became bankrupt.

Most futures exchanges limit the amount of fluctuation permitted in futures contract prices during a single trading day. The daily limit establishes the maximum amount that the price of a futures contract may vary either up or down from the previous day’s settlement price at the end of the trading session. Once the daily limit has been reached in a particular type of contract, no trades may be made on that day at a price beyond the limit. However, the daily limit governs only price movement during a particular trading day and, therefore, does not limit potential losses. In addition, the daily limit may prevent liquidation of unfavorable positions. Futures contract prices have occasionally moved to the daily limit for several consecutive trading days with little or no trading, thereby preventing prompt liquidation of futures positions and subjecting some futures traders to substantial losses.

Options Disclosure

By buying a put option, a fund obtains the right (but not the obligation) to sell the instrument underlying the option at a fixed strike price and in return a fund pays the current market price for the option (known as the option premium). A fund may terminate its position in a put option it has purchased by allowing it to expire, by exercising the option or by entering into an offsetting transaction, if a liquid market exists. If the option is allowed to expire, a fund will lose the entire premium it paid. If a fund exercises a put option on a security, it will sell the instrument underlying the option at the strike price. Purchasing an option on a futures contract does not require a fund to make margin payments unless the option is exercised. The buyer of a typical put option can expect to realize a gain if the value of the underlying instrument falls substantially. However, if the price of the instrument underlying the option does not fall enough to offset the cost of purchasing the option, a put buyer can expect to suffer a loss limited to the amount of the premium paid, plus related transaction costs.

11

The features of call options are essentially the same as those of put options, except that the buyer of a call option obtains the right to purchase, rather than sell, the instrument underlying the option at the option’s strike price. The buyer of a typical call option can expect to realize a gain if the value of the underlying instrument increases substantially and can expect to suffer a loss if security prices do not rise sufficiently to offset the cost of the option.

When a fund writes a put option, it takes the opposite side of the transaction from the option’s buyer. In return for the receipt of the premium, a fund assumes the obligation to pay the strike price for the instrument underlying the option if the other party to the option chooses to exercise it. A fund may seek to terminate its position in a put option it writes before exercise by purchasing an offsetting option in the market at its current price. Otherwise, a fund must continue to be prepared to pay the strike price while the option is outstanding, regardless of price changes, and must continue to post margin as discussed below. If the price of the underlying instrument rises, a put writer would generally realize as profit the premium it received. If the price of the underlying instrument remains the same over time, it is likely that the writer will also profit, because it should be able to close out the option at a lower price. If the price of the underlying instrument falls, the put writer would expect to suffer a loss.

A fund writing a call option is obligated to sell or deliver the option’s underlying instrument in return for the strike price upon exercise of the option. Writing calls generally is a profitable strategy if the price of the underlying instrument remains the same or falls. A call writer offsets part of the effect of a price decline by receipt of the option premium, but gives up some ability to participate in security price increases. The writer of an exchange traded put or call option on a security, an index of securities or a futures contract is required to deposit cash or securities or a letter of credit as margin and to make mark to market payments of variation margin as the position becomes unprofitable.

Although they do not currently intend to do so, the funds may write (or sell) call options that obligate them to sell (or deliver) the option’s underlying instrument upon exercise of the option. While the receipt of option premiums would mitigate the effects of price declines, the funds would give up some ability to participate in a price increase on the underlying security. If a fund were to engage in options transactions, it would own the futures contract at the time a call was written and would keep the contract open until the obligation to deliver it pursuant to the call expired.

Restrictions on the Use of Futures Contracts and Options

Each fund may enter into futures contracts, options, options on futures contracts, or swap agreements as permitted by its investment policies and the Commodity Futures Trading Commission (CFTC) rules. The advisor to each fund has claimed an exclusion from the definition of the term “commodity pool operator” under the Commodity Exchange Act and, therefore, the advisor is not subject to registration or regulation as a commodity pool operator under that Act with respect to its provision of services to each fund.

The CFTC recently adopted certain rule amendments that may impose additional limits on the ability of a fund to invest in futures contracts, options on futures, swaps, and certain other commodity interests if its investment advisor does not register with the CFTC as a “commodity pool operator” with respect to such fund. It is expected that the funds will be able to execute their investment strategies within the limits adopted by the CFTC’s rules. As a result, the advisor does not intend to register with the CFTC as a commodity pool operator on behalf of any of the funds. In the event that one of the funds engages in transactions that necessitate future registration with the CFTC, the advisor will register as a commodity pool operator and comply with applicable regulations with respect to that fund.

To the extent required by law, each fund will segregate cash, cash equivalents or other appropriate liquid securities on its records in an amount sufficient to cover its obligations under the futures contracts and options.

Initial Public Offerings

The funds may invest in initial public offerings (IPOs) of common stock or other equity securities issued by a company. The purchase of securities in an IPO may involve higher transaction costs than those associated with the purchase of securities already traded on exchanges or other established markets. In addition to the risks associated with equity securities generally, IPO securities may be subject to additional risk due to factors such as the absence of a prior public market, unseasoned trading and speculation, a potentially small number of securities available for trading, limited information about the issuer and other factors. These factors may cause IPO shares to be volatile in price. While a fund may hold IPO securities for a period of time, it may sell them in the aftermarket soon after the purchase, which could increase portfolio turnover and lead to increased expenses such as commissions and transaction costs. Investments in IPOs could have a magnified impact (either positive or negative) on performance if a fund’s assets are relatively small. The impact of IPOs on a fund’s performance may tend to diminish as assets grow.

12

Investments in Issuers with Limited Operating Histories

The funds may invest the following portions of their assets in the equity securities of issuers with limited operating histories: Global Growth, International Growth, Focused International Growth, NT International Growth and NT International Small-Mid Cap up to 5%; Emerging Markets, Emerging Markets Small Cap, International Discovery, International Value, NT Emerging Markets and NT International Value up to 10%; and International Opportunities and Global Small Cap up to 20%. The portfolio managers consider an issuer to have a limited operating history if that issuer has a record of less than three years of continuous operation. The managers will consider periods of capital formation, incubation, consolidations, and research and development in determining whether a particular issuer has a record of three years of continuous operation.

Investments in securities of issuers with limited operating histories may involve greater risks than investments in securities of more mature issuers. By their nature, such issuers present limited operating histories and financial information upon which the managers may base their investment decision on behalf of the funds. In addition, financial and other information regarding such issuers, when available, may be incomplete or inaccurate.

For purposes of this limitation, “issuers” refers to operating companies that issue securities for the purposes of issuing debt or raising capital as a means of financing their ongoing operations. It does not, however, refer to entities, corporate or otherwise, that are created for the express purpose of securitizing obligations or income streams. For example, a fund’s investments in a trust created for the purpose of pooling mortgage obligations or other financial assets would not be subject to the limitation.

Loans of Portfolio Securities

In order to realize additional income, a fund may lend its portfolio securities. Such loans may not exceed one-third of the fund’s total assets valued at market, however, this limitation does not apply to purchases of debt securities in accordance with the fund’s investment objectives, policies and limitations, or to repurchase agreements with respect to portfolio securities.

Cash received from the borrower as collateral through loan transactions may be invested in other eligible securities. Investing this cash subjects that investment to market appreciation or depreciation. If a borrower defaults on a securities loan because of insolvency or other reasons, the lending fund could experience delays or costs in recovering the securities it loaned; if the value of the loaned securities increased over the value of the collateral, the fund could suffer a loss. To minimize the risk of default on securities loans, the advisor adheres to guidelines prescribed by the Board of Directors governing lending of securities. These guidelines strictly govern:

(1) the type and amount of collateral that must be received by the fund;

(2) the circumstances under which additions to that collateral must be made by borrowers;

(3) the return to be received by the fund on the loaned securities;

(4) the limitations on the percentage of fund assets on loan; and

(5) the credit standards applied in evaluating potential borrowers of portfolio securities.

In addition, the guidelines require that the fund have the option to terminate any loan of a portfolio security at any time and set requirements for recovery of securities from borrowers.

Other Investment Companies

Each of the funds may invest in other investment companies, such as closed-end investment companies, unit investment trusts, exchange traded funds (ETFs) and other open-end investment companies, provided that the investment is consistent with the fund’s investment policies and restrictions. Under the Investment Company Act, a fund’s investment in such securities, subject to certain exceptions, currently is limited to

• 3% of the total voting stock of any one investment company,

• 5% of the fund’s total assets with respect to any one investment company, and

• 10% of the fund’s total assets in the aggregate.

A fund’s investments in other investment companies may include money market funds managed by the advisor. Investments in money market funds are not subject to the percentage limitations set forth above.

Such purchases will be made in the open market where no commission or profit to a sponsor or dealer results from the purchase other than the customary brokers’ commissions. As a shareholder of another investment company, a fund would bear, along with other shareholders, its pro rata portion of the other investment company’s expenses, including advisory fees. These expenses would be in addition to the management fee that each fund bears directly in connection with its own operations.

13

ETFs, such as Standard & Poor’s Depositary Receipts (SPDRs) and the Barclays Aggregate Bond ETF, are a type of fund bought and sold on a securities exchange. An ETF trades like common stock and usually represents a fixed portfolio of securities designed to track the performance and dividend yield of a particular domestic or foreign market index. A fund may purchase an ETF to temporarily gain exposure to a portion of the U.S. or a foreign market while awaiting purchase of underlying securities. The risks of owning an ETF generally reflect the risks of owning the underlying securities they are designed to track, although the lack of liquidity on an ETF could result in it being more volatile and the market price for the ETF may be higher than or lower than the ETF’s net asset value. Additionally, ETFs have management fees, which increase their cost.

Repurchase Agreements

Each fund may invest in repurchase agreements when they present an attractive short-term return on cash that is not otherwise committed to the purchase of securities pursuant to the investment policies of that fund.

A repurchase agreement occurs when, at the time the fund purchases an interest-bearing obligation, the seller (a bank or a broker-dealer registered under the Securities Exchange Act of 1934) agrees to purchase it on a specified date in the future at an agreed-upon price. The repurchase price reflects an agreed-upon interest rate during the time the fund’s money is invested in the security.

Because the security purchased constitutes collateral security for the repurchase obligation, a repurchase agreement can be considered a loan collateralized by the security purchased. The fund’s risk is the seller’s ability to pay the agreed-upon repurchase price on the repurchase date. If the seller defaults, the fund may incur costs in disposing of the collateral, which would reduce the amount realized thereon. If the seller seeks relief under the bankruptcy laws, the disposition of the collateral may be delayed or limited. To the extent the value of the security decreases, the fund could experience a loss.

The funds will limit repurchase agreement transactions to securities issued by the U.S. government, its agencies and instrumentalities, and will enter into such transactions with those banks and securities dealers who are deemed creditworthy by the funds’ advisor.

Repurchase Agreements maturing in more than seven days would count toward a fund’s 15% limit on illiquid securities.

Restricted and Illiquid Securities

The funds may, from time to time, purchase restricted or illiquid securities, including Rule 144A securities, when they present attractive investment opportunities that otherwise meet the funds’ criteria for selection. Restricted securities include securities that cannot be sold to the public without registration under the Securities Act of 1933 or the availability of an exemption from registration, or that are “not readily marketable” because they are subject to other legal or contractual delays in or restrictions on resale. Rule 144A securities are securities that are privately placed with and traded among qualified institutional investors rather than the general public. Although Rule 144A securities are considered restricted securities, they are not necessarily illiquid.

With respect to securities eligible for resale under Rule 144A, the staff of the Securities and Exchange Commission (SEC) has taken the position that the liquidity of such securities in the portfolio of a fund offering redeemable securities is a question of fact for the Board of Directors to determine, such determination to be based upon a consideration of the readily available trading markets and the review of any contractual restrictions. Accordingly, the Board of Directors is responsible for developing and establishing the guidelines and procedures for determining the liquidity of Rule 144A securities. As allowed by Rule 144A, the Board of Directors has delegated the day-to-day function of determining the liquidity of Rule 144A securities to the portfolio managers. The board retains the responsibility to monitor the implementation of the guidelines and procedures it has adopted.

Because the secondary market for restricted securities is generally limited to certain qualified institutional investors, the liquidity of such securities may be limited accordingly and a fund may, from time to time, hold a Rule 144A or other security that is illiquid. In such an event, the portfolio managers will consider appropriate remedies to minimize the effect on such fund’s liquidity. Each of the funds may invest no more than 15% of the value of its assets in illiquid securities.

Short Sales

A fund may engage in short sales for cash management purposes only if, at the time of the short sale, the fund owns or has the right to acquire securities equivalent in kind and amount to the securities being sold short.

In a short sale, the seller does not immediately deliver the securities sold and is said to have a short position in those securities until delivery occurs. To make delivery to the purchaser, the executing broker borrows the securities being sold short on behalf of the seller. While the short position is maintained, the seller collateralizes its obligation to deliver the securities sold short in an amount equal to the proceeds of the short sale plus an additional margin amount established by the Board of Governors of the Federal Reserve. If a fund engages in a short sale, the fund’s custodian will segregate cash, cash equivalents or other appropriate liquid securities on its records in an amount sufficient to meet the purchase price. There will be certain additional transaction costs associated with short sales, but the fund will endeavor to offset these costs with income from the investment of the cash proceeds of short sales.

Short-Term Securities

In order to meet anticipated redemptions, anticipated purchases of additional securities for a fund’s portfolio, or, in some cases, for temporary defensive purposes, the funds may invest a portion of their assets in money market and other short-term securities.

Examples of those securities include:

• Securities issued or guaranteed by the U.S. government and its agencies and instrumentalities;

• Commercial Paper;

• Certificates of Deposit and Euro Dollar Certificates of Deposit;

• Bankers’ Acceptances;

• Short-term notes, bonds, debentures, or other debt instruments;

• Repurchase agreements; and

• Money market funds.

Swap Agreements

Each fund may invest in swap agreements, consistent with its investment objective and strategies. A fund may enter into a swap agreement in order to, for example, attempt to obtain or preserve a particular return or spread at a lower cost than obtaining a return or spread through purchases and/or sales of instruments in other markets; protect against currency fluctuations; attempt to manage duration to protect against any increase in the price of securities the fund anticipates purchasing at a later date; or gain exposure to certain markets in the most economical way possible.

Swap agreements are two-party contracts entered into primarily by institutional investors for periods ranging from a few weeks to more than one year. In a standard “swap” transaction, two parties agree to exchange the returns (or differentials in rates of return) earned or realized on particular predetermined investments or instruments, which may be adjusted for an interest factor. The gross returns to be exchanged or “swapped” between the parties are generally calculated with respect to a “notional amount,” i.e., the return on or increase in value of a particular dollar amount invested at a particular interest rate, in a particular foreign currency, or in a “basket” of securities representing a particular index. Forms of swap agreements include, for example, interest rate swaps, under which fixed- or floating-rate interest payments on a specific principal amount are exchanged and total return swaps, under which one party agrees to pay the other the total return of a defined underlying asset (usually an index, including inflation indexes, stock, bond or defined portfolio of loans and mortgages) in exchange for fee payments, often a variable stream of cashflows based on LIBOR. The funds may enter into credit default swap agreements to hedge an existing position by purchasing or selling credit protection. Credit default swaps enable an investor to buy/sell protection against a credit event of a specific issuer. The seller of credit protection against a security or basket of securities receives an up-front or periodic payment to compensate against potential default event(s). The fund may enhance returns by selling protection or attempt to mitigate credit risk by buying protection. Market supply and demand factors may cause distortions between the cash securities market and the credit default swap market.

Whether a fund’s use of swap agreements will be successful depends on the advisor’s ability to predict correctly whether certain types of investments are likely to produce greater returns than other investments. Interest rate swaps could result in losses if interest rate changes are not correctly anticipated by the fund. Total return swaps could result in losses if the reference index, security, or investments do not perform as anticipated by the fund. Credit default swaps could result in losses if the fund does not correctly evaluate the creditworthiness of the issuer on which the credit default swap is based. Because they are two-party contracts and because they may have terms of greater than seven days, swap agreements may be considered to be illiquid. Moreover, a fund bears the risk of loss of the amount expected to be received under a swap agreement in the event of the default or bankruptcy of a swap agreement counterparty. The funds will enter into swap agreements only with counterparties that meet certain standards of creditworthiness or that are cleared through a Derivatives Clearing Organization (“DCO”). Certain restrictions imposed on the funds by the Internal Revenue Code may limit the funds’ ability to use swap agreements.

The swaps market is an evolving market and was largely unregulated prior to the enactment of the Dodd-Frank Wall Street Reform and Consumer Protection Act (the “Dodd-Frank Act”). The Dodd-Frank Act and related regulatory developments have imposed several new requirements on swap market participants, including: (i) new registration and business conduct requirements on swap dealers; (ii) mandatory execution of certain swaps on swap execution facilities or designated contract markets; and (iii) mandatory clearing of certain swaps with DCOs. The mandatory execution and clearing requirements will occur on a phased-in basis. Although central clearing is designed to decrease counterparty risk, it does not do so entirely since a fund will still be subject to the credit risk of the central clearing entity. In addition, swaps that are not cleared will be subject to regulatory collateral requirements that could limit or adversely affect a fund’s ability to enter into such swaps. Additionally, such collateral requirements, or other government regulations, could cause a fund to terminate new or existing swaps or to realize amounts to be received under such instruments at inopportune times.

When-Issued and Forward Commitment Agreements

The funds may engage in securities transactions on a when-issued or forward commitment basis in which the transaction price and yield are each fixed at the time the commitment is made, but payment and delivery occur at a future date.

For example, a fund may sell a security and at the same time make a commitment to purchase the same or a comparable security at a future date and specified price. Conversely, a fund may purchase a security and at the same time make a commitment to sell the same or a comparable security at a future date and specified price. These types of transactions are executed simultaneously in what are known as dollar-rolls, buy/sell back transactions, cash and carry, or financing transactions. For example, a broker-dealer may seek to purchase a particular security that a fund owns. The fund will sell that security to the broker-dealer and simultaneously enter into a forward commitment agreement to buy it back at a future date. This type of transaction generates income for the fund if the dealer is willing to execute the transaction at a favorable price in order to acquire a specific security.

When purchasing securities on a when-issued or forward commitment basis, a fund assumes the rights and risks of ownership, including the risks of price and yield fluctuations. Market rates of interest on debt securities at the time of delivery may be higher or lower than those contracted for on the when-issued security. Accordingly, the value of the security may decline prior to delivery, which could result in a loss to the fund. While the fund will make commitments to purchase or sell securities with the intention of actually receiving or delivering them, it may sell the securities before the settlement date if doing so is deemed advisable as a matter of investment strategy.

In purchasing securities on a when-issued or forward commitment basis, a fund will segregate cash, cash equivalents or other appropriate liquid securities on its records in an amount sufficient to meet the purchase price. To the extent a fund remains fully invested or almost fully invested at the same time it has purchased securities on a when-issued basis, there will be greater fluctuations in its net asset value than if it solely set aside cash to pay for when-issued securities. When the time comes to pay for the when-issued securities, a fund will meet its obligations with available cash, through the sale of securities, or, although it would not normally expect to do so, by selling the when-issued securities themselves (which may have a market value greater or less than the fund’s payment obligation). Selling securities to meet when-issued or forward commitment obligations may generate taxable capital gains or losses.

Investment Policies

Unless otherwise indicated, with the exception of the percentage limitations on borrowing, the policies described below apply at the time a fund enters into a transaction. Accordingly, any later increase or decrease beyond the specified limitation resulting from a change in a fund’s assets will not be considered in determining whether it has complied with its investment policies.

Fundamental Investment Policies

The funds’ fundamental investment policies are set forth below. These investment policies, a fund’s status as diversified, and, except for Emerging Markets Small Cap, Focused International Growth, Global Small Cap, NT International Value and NT International Small-Mid Cap, a fund’s investment objective as set forth in its prospectus, may not be changed without approval of a majority of the outstanding votes of shareholders of a fund, as determined in accordance with the Investment Company Act.

Subject	Policy
Senior Securities	A fund may not issue senior securities, except as permitted under the Investment Company Act.
Borrowing	A fund may not borrow money, except that a fund may borrow for temporary or emergency purposes (not for leveraging or investment) in an amount not exceeding 33⅓% of the fund’s total assets (including the amount borrowed) less liabilities (other than borrowings).
Lending	A fund may not lend any security or make any other loan if, as a result, more than 33⅓% of the fund’s total assets would be lent to other parties, except, (i) through the purchase of debt securities in accordance with its investment objective, policies and limitations or (ii) by engaging in repurchase agreements with respect to portfolio securities.
Real Estate	A fund may not purchase or sell real estate unless acquired as a result of ownership of securities or other instruments. This policy shall not prevent a fund from investing in securities or other instruments backed by real estate or securities of companies that deal in real estate or are engaged in the real estate business.
Concentration	A fund may not concentrate its investments in securities of issuers in a particular industry (other than securities issued or guaranteed by the U.S. government or any of its agencies or instrumentalities).
Underwriting	A fund may not act as an underwriter of securities issued by others, except to the extent that the fund may be considered an underwriter within the meaning of the Securities Act of 1933 in the disposition of restricted securities.
Commodities	A fund may not purchase or sell physical commodities unless acquired as a result of ownership of securities or other instruments; provided that this limitation shall not prohibit the fund from purchasing or selling options and futures contracts or from investing in securities or other instruments backed by physical commodities.
Control	A fund may not invest for purposes of exercising control over management.

16

For purposes of the investment policy relating to senior securities, a fund may borrow from any bank provided that immediately after any such borrowing there is asset coverage of at least 300% for all borrowings of such fund. In the event that such asset coverage falls below 300%, the fund shall, within three days thereafter (not including Sundays and holidays) or such longer period as the SEC may prescribe by rules and regulations, reduce the amount of its borrowings to an extent that the asset coverage of such borrowings is at least 300%. In addition, when a fund enters into certain transactions involving potential leveraging, it will hold offsetting positions or segregate assets to cover such obligations at levels consistent with the guidance of the SEC and its staff.

For purposes of the investment policies relating to lending and borrowing, the funds have received an exemptive order from the SEC regarding an interfund lending program. Under the terms of the exemptive order, the funds may borrow money from or lend money to other American Century Investments-advised funds that permit such transactions. All such transactions will be subject to the limits for borrowing and lending set forth above. The funds will borrow money through the program only when the costs are equal to or lower than the cost of short-term bank loans. Interfund loans and borrowings normally extend only overnight, but can have a maximum duration of seven days. The funds will lend through the program only when the returns are higher than those available from other short-term instruments (such as repurchase agreements). The funds may have to borrow from a bank at a higher interest rate if an interfund loan is called or not renewed. Any delay in repayment to a lending fund could result in a lost investment opportunity or additional borrowing costs. For purposes of the funds’ investment policy relating to borrowing, short positions held by the funds are not considered borrowings.

For purposes of the investment policy relating to concentration, a fund shall not purchase any securities that would cause 25% or more of the value of the fund’s net assets at the time of purchase to be invested in the securities of one or more issuers conducting their principal business activities in the same industry, provided that

(a) there is no limitation with respect to obligations issued or guaranteed by the U.S. government, any state, territory or possession of the United States, the District of Columbia or any of their authorities, agencies, instrumentalities or political subdivisions and repurchase agreements secured by such obligations (except that an Industrial Development Bond backed only by the assets and revenues of a non-governmental user will be deemed to be an investment in the industry represented by such user),

(b) wholly owned finance companies will be considered to be in the industries of their parents if their activities are primarily related to financing the activities of their parents,

(c) utilities will be divided according to their services, for example, gas, gas transmission, electric and gas, electric, and telephone will each be considered a separate industry, and

(d) personal credit and business credit businesses will be considered separate industries.

Nonfundamental Investment Policies

In addition, the funds are subject to the following investment policies that are not fundamental. These policies, along with the investment objectives of Emerging Markets Small Cap, Focused International Growth, Global Small Cap, NT International Value and NT International Small-Mid Cap, as set forth in their prospectuses, may be changed by the Board of Directors.

Subject	Policy
Leveraging	A fund may not purchase additional investment securities at any time during which outstanding borrowings exceed 5% of the total assets of the fund.
Liquidity	A fund may not purchase any security or enter into a repurchase agreement if, as a result, more than 15% of its net assets would be invested in illiquid securities. Illiquid securities include repurchase agreements not entitling the holder to payment of principal and interest within seven days and in securities that are illiquid by virtue of legal or contractual restrictions on resale or the absence of a readily available market.
Short Sales	A fund may not sell securities short, unless it owns or has the right to obtain securities equivalent in kind and amount to the securities sold short, and provided that transactions in futures contracts and options are not deemed to constitute selling securities short.
Margin	A fund may not purchase securities on margin, except to obtain such short-term credits as are necessary for the clearance of transactions, and provided that margin payments in connection with futures contracts and options on futures contracts shall not constitute purchasing securities on margin.
Futures and Options	A fund may enter into futures contracts and write and buy put and call options relating to futures contracts. A fund may not, however, enter into leveraged futures transactions if it would be possible for the fund to lose more than the notional value of the investment.
Issuers with Limited Operating Histories	A fund may invest a portion of its assets in the equity securities of issuers with limited operating histories. See Investment in Issuers with Limited Operating Histories under Fund Investments and Risks. An issuer is considered to have a limited operating history if that issuer has a record of less than three years of continuous operation. Periods of capital formation, incubation, consolidations, and research and development may be considered in determining whether a particular issuer has a record of three years of continuous operation.

17

For purposes of the funds’ investment policy relating to leveraging, short positions held by the funds are not considered borrowings. 

The Investment Company Act imposes certain additional restrictions upon the funds’ ability to acquire securities issued by insurance companies, broker-dealers, underwriters or investment advisors, and upon transactions with affiliated persons as defined by the Act. It also defines and forbids the creation of cross and circular ownership. Neither the SEC nor any other agency of the federal or state government participates in or supervises the management of the funds or their investment practices or policies.

Portfolio Turnover

The portfolio turnover rate of each fund for its most recent fiscal year is included in the Fund Summary section of that fund’s prospectus. The portfolio turnover rate for each fund’s last five fiscal years (or a shorter period if the fund is less than five years old) is shown in the Financial Highlights tables in the prospectus.

The portfolio managers will sell securities without regard to the length of time the security has been held. Accordingly, each fund’s portfolio turnover rate may be substantial.

The portfolio managers intend to purchase a given security whenever they believe it will contribute to the stated objective of a particular fund. In order to achieve each fund’s investment objective, the portfolio managers may sell a given security, regardless of the length of time it has been held in the portfolio, and regardless of the gain or loss realized on the sale. The managers may sell a portfolio security if they believe that the security is not fulfilling its purpose because, among other things, it did not live up to the managers’ expectations, because it may be replaced with another security holding greater promise, because it has reached its optimum potential, because of a change in the circumstances of a particular company or industry or in general economic conditions, or because of some combination of such reasons.

When a general decline in security prices is anticipated, the funds may decrease or eliminate entirely their equity positions and increase their cash positions, and when a general rise in price levels is anticipated, the funds may increase their equity positions and decrease their cash positions. However, it should be expected that the funds will, under most circumstances, be essentially fully invested in equity securities.

Because investment decisions are based on a particular security’s anticipated contribution to a fund’s investment objective, the managers believe that the rate of portfolio turnover is irrelevant when they determine that a change is required to pursue the fund’s investment objective. As a result, a fund’s annual portfolio turnover rate cannot be anticipated and may be higher than that of other mutual funds with similar investment objectives. Higher turnover would generate correspondingly greater brokerage commissions, which is a cost the funds pay directly. Portfolio turnover also may affect the character of capital gains realized and distributed by the fund, if any, since short-term capital gains are characterized as ordinary income.

Because the managers do not take portfolio turnover rate into account in making investment decisions, (1) the managers have no intention of maintaining any particular rate of portfolio turnover, whether high or low, and (2) the portfolio turnover rates in the past should not be considered as representative of the rates that will be attained in the future.

Disclosure of Portfolio Holdings

The advisor has adopted policies and procedures with respect to the disclosure of fund portfolio holdings and characteristics, which are described below.

Distribution to the Public

Full portfolio holdings for each fund will be made available for distribution 30 days after the end of each calendar quarter, and will be posted on americancentury.com at approximately the same time. This disclosure is in addition to the portfolio disclosure in annual and semi-annual shareholder reports, and on Form N-Q, which disclosures are filed with the Securities and Exchange Commission within 60 days of each fiscal quarter end and also posted on americancentury.com at the time the filings are made.

Top 10 holdings for each fund will be made available for distribution 30 days after the end of each month, and will be posted on americancentury.com at approximately the same time.

Portfolio characteristics that are derived from portfolio holdings but do not identify any specific security will be made available for distribution 15 days after the end of the period to which such data relates. Characteristics that identify any specific security will be made available 30 days after the end of the period to which such data relates. Characteristics in both categories will generally be posted on americancentury.com at approximately the time they are made available for distribution. Data derived from portfolio returns and any other characteristics not deemed confidential will be available for distribution at any time. The advisor may make determinations of confidentiality on a fund-by-fund basis, and may add or delete characteristics to or from those considered confidential at any time.

Any American Century Investments fund that sells securities short as an investment strategy will disclose full portfolio holdings only in annual and semi-annual shareholder reports and on form N-Q. These funds will make long holdings available for distribution 30 days after the end of each calendar quarter, but the funds will keep short holdings confidential. Top 10 long holdings and portfolio characteristics will be made available for distribution in accordance with the policies set forth above.

18

So long as portfolio holdings are disclosed in accordance with the above parameters, the advisor makes no distinction among different categories of recipients, such as individual investors, institutional investors, intermediaries that distribute the funds’ shares, third-party service providers, rating and ranking organizations, and fund affiliates. Because this information is publicly available and widely disseminated, the advisor places no conditions or restrictions on, and does not monitor, its use. Nor does the advisor require special authorization for its disclosure.

Accelerated Disclosure

The advisor recognizes that certain parties, in addition to the advisor and its affiliates, may have legitimate needs for information about portfolio holdings and characteristics prior to the times prescribed above. Such accelerated disclosure is permitted under the circumstances described below.

Ongoing Arrangements

Certain parties, such as investment consultants who provide regular analysis of fund portfolios for their clients and intermediaries who pass through information to fund shareholders, may have legitimate needs for accelerated disclosure. These needs may include, for example, the preparation of reports for customers who invest in the funds, the creation of analyses of fund characteristics for intermediary or consultant clients, the reformatting of data for distribution to the intermediary’s or consultant’s clients, and the review of fund performance for ERISA fiduciary purposes.

In such cases, accelerated disclosure is permitted if the service provider enters an appropriate non-disclosure agreement with the funds’ distributor in which it agrees to treat the information confidentially until the public distribution date and represents that the information will be used only for the legitimate services provided to its clients (i.e., not for trading). Non-disclosure agreements require the approval of an attorney in the advisor’s legal department. The advisor’s compliance department receives quarterly reports detailing which clients received accelerated disclosure, what they received, when they received it and the purposes of such disclosure. Compliance personnel are required to confirm that an appropriate non-disclosure agreement has been obtained from each recipient identified in the reports.

Once a party has executed a non-disclosure agreement, it may receive any or all of the following data for funds in which its clients have investments or are actively considering investment:

(1) Full holdings quarterly as soon as reasonably available;

(2) Full holdings monthly as soon as reasonably available;

(3) Top 10 holdings monthly as soon as reasonably available; and

(4) Portfolio characteristics monthly as soon as reasonably available.

The types, frequency and timing of disclosure to such parties vary. In most situations, the information provided pursuant to a non-disclosure agreement is limited to certain portfolio characteristics and/or top 10 holdings, which information is provided on a monthly basis. In limited situations, and when approved by a member of the legal department and responsible chief investment officer, full holdings may be provided.

Single Event Requests

In certain circumstances, the advisor may provide fund holding information on an accelerated basis outside of an ongoing arrangement with manager-level or higher authorization. For example, from time to time the advisor may receive requests for proposals (RFPs) from consultants or potential clients that request information about a fund’s holdings on an accelerated basis. As long as such requests are on a one-time basis, and do not result in continued receipt of data, such information may be provided in the RFP as of the most recent month end regardless of lag time. Such information will be provided with a confidentiality legend and only in cases where the advisor has reason to believe that the data will be used only for legitimate purposes and not for trading.

In addition, the advisor occasionally may work with a transition manager to move a large account into or out of a fund. To reduce the impact to the fund, such transactions may be conducted on an in-kind basis using shares of portfolio securities rather than cash. The advisor may provide accelerated holdings disclosure to the transition manager with little or no lag time to facilitate such transactions, but only if the transition manager enters into an appropriate non-disclosure agreement.

Service Providers

Various service providers to the funds and the funds’ advisor must have access to some or all of the funds’ portfolio holdings information on an accelerated basis from time to time in the ordinary course of providing services to the funds. These service providers include the funds’ custodian (daily, with no lag), auditors (as needed) and brokers involved in the execution of fund trades (as needed). Additional information about these service providers and their relationships with the funds and the advisor are provided elsewhere in this statement of additional information. In addition, the funds’ investment advisor may use analytical systems provided by third party data aggregators who have access to the funds’ portfolio holdings daily, with no lag. These data aggregators enter into separate non-disclosure agreements after authorization by an appropriate officer of the advisor. The agreements with service providers and data aggregators generally require that they treat the funds’ portfolio holdings information confidentially until the public distribution date and represent that the information will be used only for the legitimate services it provides (i.e., not for trading).

21

Additional Safeguards

The advisor’s policies and procedures include a number of safeguards designed to control disclosure of portfolio holdings and characteristics so that such disclosure is consistent with the best interests of fund shareholders, including procedures to address conflicts between the interests of shareholders and those of the advisor and its affiliates. First, the frequency with which this information is disclosed to the public, and the length of time between the date of the information and the date on which the information is disclosed, are selected to minimize the possibility of a third party improperly benefiting from fund investment decisions to the detriment of fund shareholders. In the event that a request for portfolio holdings or characteristics creates a potential conflict of interest that is not addressed by the safeguards and procedures described above, the advisor’s procedures require that such requests may only be granted with the approval of the advisor’s legal department and the relevant chief investment officers. In addition, distribution of portfolio holdings information, including compliance with the advisor’s policies and the resolution of any potential conflicts that may arise, is monitored quarterly by the advisor’s compliance department. Finally, the funds’ Board of Directors exercises oversight of disclosure of the funds’ portfolio securities. The board has received and reviewed a summary of the advisor’s policy and is informed on a quarterly basis of any changes to or violations of such policy detected during the prior quarter.

Neither the advisor nor the funds receive any compensation from any party for the distribution of portfolio holdings information.

The advisor reserves the right to change its policies and procedures with respect to the distribution of portfolio holdings information at any time. There is no guarantee that these policies and procedures will protect the funds from the potential misuse of holdings information by individuals or firms in possession of such information.

22

Management

The Board of Directors

The individuals listed below serve as directors of the funds. Each director will continue to serve in this capacity until death, retirement, resignation or removal from office. The board has adopted a mandatory retirement age for directors who are not “interested persons,” as that term is defined in the Investment Company Act (independent directors). Independent directors shall retire by December 31 of the year in which they reach their 75^th birthday.

Mr. Thomas is an “interested person” because he currently serves as President and Chief Executive Officer of American Century Companies, Inc. (ACC), the parent company of American Century Investment Management, Inc. (ACIM or the advisor). Mr. Fink is treated as an “interested person” because of his recent employment with ACC and American Century Services, LLC (ACS). The other directors (more than three-fourths of the total number) are independent. They are not employees, directors or officers of, and have no financial interest in, ACC or any of its wholly owned, direct or indirect, subsidiaries, including ACIM, American Century Investment Services, Inc. (ACIS) and ACS, and they do not have any other affiliations, positions or relationships that would cause them to be considered “interested persons” under the Investment Company Act. The directors serve in this capacity for seven (in the case of Mr. Thomas, 15) registered investment companies in the American Century Investments family of funds.

The following table presents additional information about the directors. The mailing address for each director is 4500 Main Street, Kansas City, Missouri 64111.

Qualifications of Directors

Generally, no one factor was decisive in the selection of the directors to the board. Qualifications considered by the board to be important to the selection and retention of directors include the following: (i) the individual’s business and professional experience and accomplishments; (ii) the individual’s educational background and accomplishments; (iii) the individual’s experience and expertise performing senior policy-making functions in business, government, education, accounting, law and/or administration; (iv) how the individual’s expertise and experience would contribute to the mix of relevant skills and experience on the board; (v) the individual’s ability to work effectively with the other members of the board; and (vi) the individual’s ability and willingness to make the time commitment necessary to serve as an effective director. In addition, the individuals’ ability to review and critically evaluate information, their ability to evaluate fund service providers, their ability to exercise good business judgment on behalf of fund shareholders, their prior service on the board, and their familiarity with the funds are considered important assets. 

When assessing potential new directors, the board has a policy of considering individuals from various and diverse backgrounds. Such diverse backgrounds may include differences in professional experience, education, individual skill sets and other individual attributes. Additional information about each director’s individual educational and professional experience (supplementing the information provided in the table above) follows and was considered as part of his or her nomination to, or retention on, the board.

Responsibilities of the Board

The board is responsible for overseeing the advisor’s management and operations of the funds pursuant to the management agreements. Directors also have significant responsibilities under the federal securities laws. Among other things, they:

• oversee the performance of the funds;

• oversee the quality of the advisory and shareholder services provided by the advisor and other service providers to the funds;

• review annually the fees paid to the advisor for its services;

• monitor potential conflicts of interest between the funds and their affiliates, including the advisor;

• oversee custody of assets and the valuation of securities; and

• oversee the funds’ compliance program.

In performing their duties, board members receive detailed information about the funds, the advisor and other service providers to the funds regularly throughout the year, and meet at least quarterly with management of the advisor to review reports about fund operations. The directors’ role is to provide oversight and not to provide day-to-day management.

24

The board has all powers necessary or convenient to carry out its responsibilities. Consequently, the board may adopt bylaws providing for the regulation and management of the affairs of the funds and may amend and repeal them to the extent that such bylaws do not reserve that right to the funds’ shareholders. They may increase or reduce the number of board members and may, subject to the Investment Company Act, fill board vacancies. Board members also may elect and remove such officers and appoint and terminate such agents as they consider appropriate. They may establish and terminate committees consisting of two or more directors who may exercise the powers and authority of the board as determined by the directors. They may, in general, delegate such authority as they consider desirable to any officer of the funds, to any board committee and to any agent or employee of the funds or to any custodian, transfer agent, investor servicing agent, principal underwriter or other service provider for a fund.

To communicate with the board, or a member of the board, a shareholder should send a written communication addressed to the attention of the corporate secretary (the “Corporate Secretary”) at American Century funds, P.O. Box 418210, Kansas City, Missouri 64141-9210. Shareholders who prefer to communicate by email may send their comments to corporatesecretary@americancentury.com. The Corporate Secretary will forward all such communications to each member of the Compliance and Shareholder Services Committee, or if applicable, the individual director(s) and/or committee chair named in the correspondence. However, if a shareholder communication is addressed exclusively to the funds’ independent directors, the Corporate Secretary will forward the communication to the Compliance and Shareholder Services Committee chair, who will determine the appropriate action.

Board Leadership Structure and Standing Board Committees

James A. Olson currently serves as the independent chairman of the board and has served in such capacity since 2014. All of the board’s members except for Jonathan S. Thomas and Barry Fink are independent directors. The independent directors meet separately, as needed and at least in conjunction with each quarterly meeting of the board, to consider a variety of matters that are scheduled to come before the board and meet periodically with the funds’ Chief Compliance Officer and fund auditors. They are advised by independent legal counsel. No independent director may serve as an officer or employee of a fund. The board has also established several committees, as described below. The board believes that the current leadership structure, with independent directors filling all but two positions on the board, with an independent director serving as chairman of the board, and with the board committees (with the exception of the Executive Committee) comprised only of directors who are not currently employed by ACC or any of its subsidiaries, is appropriate and allows for independent oversight of the funds.

The board has an Audit Committee that approves the funds’ (or corporation’s) engagement of the independent registered public accounting firm and recommends approval of such engagement to the independent directors. The committee also oversees the activities of the accounting firm, receives regular reports regarding fund accounting, oversees securities valuation (approving the funds’ valuation policy and receiving reports regarding instances of fair valuation thereunder) and receives regular reports from the advisor’s internal audit department. The committee currently consists of Stephen E. Yates (chair), M. Jeannine Strandjord and John R. Whitten. None of its members are “interested persons” as that term is defined in the Investment Company Act. It met four times during the fiscal year ended November 30, 2015.

The board has a Governance Committee that is responsible for reviewing board procedures and committee structures. The committee also considers and recommends individuals for nomination as directors, and may recommend the creation of new committees. The names of potential director candidates may be drawn from a number of sources, including members of the board, management and shareholders. Shareholders may submit director nominations at any time to the Corporate Secretary, American Century funds, P.O. Box 418210, Kansas City, MO 64141-9210. When submitting nominations, shareholders should include the name, age and address of the candidate, as well as a detailed resume of the candidate’s qualifications and a signed statement from the candidate of his/her willingness to serve on the board. Shareholders submitting nominations should also include information concerning the number of fund shares and length of time held by the shareholder, and if applicable, similar information for the potential candidate. All nominations submitted by shareholders will be forwarded to the chair of the Governance Committee for consideration. The Corporate Secretary will maintain copies of such materials for future reference by the committee when filling board positions.

If this process yields more than one desirable candidate, the committee will rank them by order of preference depending on their qualifications and the funds’ needs. The candidate(s) may then be contacted to evaluate their interest and be interviewed by the full committee. Based upon its evaluation and any appropriate background checks, the committee will decide whether to recommend a candidate’s nomination to the board.

The Governance Committee also may recommend the creation of new committees, evaluate the membership structure of new and existing committees, consider the frequency and duration of board and committee meetings and otherwise evaluate the responsibilities, processes, resources, performance and compensation of the board. The committee currently consists of Andrea C. Hall (chair), Jan M. Lewis, James A. Olson, M. Jeannine Strandjord, John R. Whitten and Stephen E. Yates. None of its members are “interested persons” as that term is defined in the Investment Company Act. It met three times during the fiscal year ended November 30, 2015.

25

The board also has a Compliance and Shareholder Services Committee, which reviews the results of the funds’ compliance testing program, meets regularly with the funds’ Chief Compliance Officer, reviews shareholder communications, reviews quarterly reports regarding the quality of shareholder service provided by the advisor, and monitors implementation of the funds’ Code of Ethics. The committee currently consists of Jan M. Lewis (chair), Barry Fink, Andrea C. Hall and James A. Olson. It met four times during the fiscal year ended November 30, 2015.

The board has a Fund Performance Review Committee that meets quarterly to review the investment activities and strategies used to manage fund assets and monitor investment performance. The committee regularly receives reports from the advisor’s chief investment officer, portfolio managers and other investment personnel concerning the funds’ efforts to achieve their investment objectives. The committee also receives information regarding fund trading activities and monitors derivative usage. The committee does not review individual security selections. The committee currently consists of John R. Whitten (chair), Barry Fink, Andrea C. Hall, Jan M. Lewis, James A. Olson, M. Jeannine Strandjord and Stephen E. Yates. The committee met four times during the fiscal year ended November 30, 2015.

Finally, the board has an Executive Committee that performs the functions of the board between board meetings, subject to the limitations on its power set out in the Maryland General Corporation Law and except for matters requiring the action of the entire board under the Investment Company Act. The committee currently consists of James A. Olson (chair), Andrea C. Hall and Jonathan S. Thomas. The committee did not meet during the fiscal year ended November 30, 2015.

Risk Oversight by the Board

As previously disclosed, the board oversees the advisor’s management of the funds and meets at least quarterly with management of the advisor to review reports and receive information regarding fund operations. Risk oversight relating to the funds is one component of the board’s oversight and is undertaken in connection with the duties of the board. As described above, the board’s committees assist the board in overseeing various types of risks relating to the funds, including, but not limited to, investment risk, operational risk and enterprise risk. The board receives regular reports from each committee regarding the committee’s areas of oversight responsibility and, through those reports and its regular interactions with management of the advisor during and between meetings, analyzes, evaluates, and provides feedback on the advisor’s risk management processes. In addition, the board receives information regarding, and has discussions with senior management of the advisor about, the advisor’s enterprise risk management systems and strategies, including an annual review of the advisor’s risk management practices. There can be no assurance that all elements of risk, or even all elements of material risk, will be disclosed to or identified by the board, or that the advisor’s risk management systems and strategies, and the Board’s oversight thereof, will mitigate all elements of risk, or even all elements of material risk to the funds.

Board Compensation

For the fiscal year ended November 30, [2014], the funds and the American Century family of funds paid the directors listed in the following table the amounts shown. Under the terms of the management agreement with the advisor, the funds are responsible for paying such fees and expenses. Neither Jonathan Thomas nor any officers of the funds receives compensation from the funds.

Name of Director	Total Compensation from the Funds	Total Compensation from the American Century Investments Family of Funds

Interested Director
Barry Fink	$11,141	$182,078

¹  Mr. Brown retired from the board on December 31, 2015.

²  Includes compensation paid to the directors for the fiscal year ended November 30, [2014], and also includes amounts deferred at the election of the directors under the American Century Mutual Funds’ Independent Directors’ Deferred Compensation Plan.

³  Includes compensation paid by the investment companies of the American Century Investments family of funds served by this board. The total amount of deferred compensation included in the table is as follows: Mr. Brown, $13,564; Dr. Hall, $13,000; Ms. Lewis, $17,840; Mr. Olson, $210,490; Mr. Pratt, $2,538; Ms. Strandjord, $229,156; Mr. Whitten, $176,156; and Mr. Yates, $317,156. [UPDATE]

26

None of the funds currently provides any pension or retirement benefits to the directors except pursuant to the American Century Mutual Funds’ Independent Directors’ Deferred Compensation Plan adopted by the corporation. Under the plan, the independent directors may defer receipt of all or any part of the fees to be paid to them for serving as directors of the funds. All deferred fees are credited to accounts established in the names of the directors. The amounts credited to each account then increase or decrease, as the case may be, in accordance with the performance of one or more American Century funds selected by the directors. The account balance continues to fluctuate in accordance with the performance of the selected fund or funds until final payment of all amounts credited to the account. Directors are allowed to change their designation of funds from time to time.

Generally, deferred fees are not payable to a director until the distribution date elected by the director in accordance with the terms of the plan. Such distribution date may be a date on or after the director’s retirement date, but may be earlier if the director agrees not to make any additional deferrals. Distributions may commence prior to the elected payment date for certain reasons specified in the plan, such as unforeseeable emergencies, death or disability. Directors may receive deferred fee account balances either in a lump sum payment or in substantially equal installment payments to be made over a period not to exceed 10 years. Upon the death of a director, all remaining deferred fee account balances are paid to the director’s beneficiary or, if none, to the director’s estate.

The plan is an unfunded plan and, accordingly, the funds have no obligation to segregate assets to secure or fund the deferred fees. To date, the funds have met all payment obligations under the plan. The rights of directors to receive their deferred fee account balances are the same as the rights of a general unsecured creditor of the funds. The plan may be terminated at any time by the administrative committee of the plan. If terminated, all deferred fee account balances will be paid in a lump sum.

Code of Ethics

The funds, their investment advisor, principal underwriter and, if applicable, subadvisor have adopted codes of ethics under Rule 17j-1 of the Investment Company Act. They permit personnel subject to the codes to invest in securities, including securities that may be purchased or held by the funds, provided that they first obtain approval from the compliance department before making such investments.

29

Proxy Voting Policies

The advisor is responsible for exercising the voting rights associated with the securities purchased and/or held by the funds. In exercising its voting obligations, the advisor is guided by general fiduciary principles. It must act prudently, solely in the interest of the funds, and for the exclusive purpose of providing benefits to them. The advisor attempts to consider all factors of its vote that could affect the value of the investment. The funds’ Board of Directors has approved the advisor’s proxy voting policies to govern the advisor’s proxy voting activities.

The advisor and the board have agreed on certain significant contributors to shareholder value with respect to a number of matters that are often the subject of proxy solicitations for shareholder meetings. The proxy voting policies specifically address these considerations and establish a framework for the advisor’s consideration of the vote that would be appropriate for the funds. In particular, the proxy voting policies outline principles and factors to be considered in the exercise of voting authority for proposals addressing:

■	Routine Matters • Election of Directors
	• Ratification of Selection of Auditors
■	Compensation Matters
	• Executive Compensation
	• Equity-Based Compensation Plans
■	Anti-Takeover Proposals
	• Cumulative Voting
	• Staggered Boards
	• “Blank Check” Preferred Stock
	• Elimination of Preemptive Rights
	• Non-targeted Share Repurchase
	• Increase in Authorized Common Stock
	• “Supermajority” Voting Provisions or Super Voting Share Classes
	• “Fair Price” Amendments
	• Limiting the Right to Call Special Shareholder Meetings
	• Poison Pills or Shareholder Rights Plans
	• Golden Parachutes
	• Reincorporation
	• Confidential Voting
	• Opting In or Out of State Takeover Laws
■	Other Matters
	• Shareholder Proposals Involving Social, Moral or Ethical Matters
	• Anti-Greenmail Proposals
	• Changes to Indemnification Provisions
	• Non-Stock Incentive Plans
	• Director Tenure
	• Directors’ Stock Options Plans
	• Director Share Ownership
	• Non-U.S. Proxies

Finally, the proxy voting policies establish procedures for voting of proxies in cases in which the advisor may have a potential conflict of interest. Companies with which the advisor has direct business relationships could theoretically use these relationships to attempt to unduly influence the manner in which American Century Investments votes on matters for the funds. To ensure that such a conflict of interest does not affect proxy votes cast for the funds, all discretionary (including case-by-case) voting for these companies will be voted in direct consultation with a committee of the independent directors of the funds.

30

In addition, to avoid any potential conflict of interest that may arise when one American Century Investments fund owns shares of another American Century Investments fund, the advisor will “echo vote” such shares, if possible. That is, it will vote the shares in the same proportion as the vote of all other holders of the shares. Shares of American Century Investments “NT” funds will be voted in the same proportion as the vote of the shareholders of the corresponding American Century Investments policy portfolio for proposals common to both funds where possible. For example, NT International Growth Fund shares will be echo voted in accordance with the votes of International Growth Fund shareholders. In all other cases, the shares will be voted in direct consultation with a committee of the independent directors of the voting fund.

A copy of the advisor’s proxy voting policies and information regarding how the advisor voted proxies relating to portfolio securities during the most recent 12-month period ended June 30 are available on the About Us page at americancentury.com. The advisor’s proxy voting record also is available on the SEC’s website at sec.gov.

The Funds’ Principal Shareholders

A list of the funds’ principal shareholders appears in Appendix A.

Service Providers

The funds have no employees. To conduct the funds’ day-to-day activities, the corporation has hired a number of service providers. Each service provider has a specific function to fill on behalf of the funds that is described below.

ACIM, ACS and ACIS are wholly owned, directly or indirectly, by ACC. The Stowers Institute for Medical Research (SIMR) controls ACC by virtue of its beneficial ownership of more than 25% of the voting securities of ACC. SIMR is part of a not-for-profit biomedical research organization dedicated to finding the keys to the causes, treatments and prevention of disease.

Investment Advisor

American Century Investment Management, Inc. (ACIM) serves as the investment advisor for each of the funds. A description of the responsibilities of the advisor appears in each prospectus under the heading Management.

For services provided to each fund, the advisor receives a unified management fee based on a percentage of the daily net assets of each class of shares of the fund. For more information about the unified management fee, see The Investment Advisor under the heading Management in each fund’s prospectus. The amount of the fee is calculated daily and paid monthly in arrears. For each fund with a stepped fee schedule, the rate of the fee is determined by applying the formula indicated in the table below. This formula takes into account the assets of the fund as well as certain assets, if any, of other clients of the advisor outside the American Century Investments fund family (such as subadvised funds and separate accounts) that use very similar investment teams and strategies (strategy assets). For a fund with a corresponding NT fund, strategy assets for both funds also include the assets of the other. The use of strategy assets, rather than fund assets, in calculating the fee rate for a particular fund could allow the fund to realize scheduled cost savings more quickly. However, it is possible that a fund’s strategy assets will not include assets of other client accounts or that any such assets may not be sufficient to result in a lower fee rate. The management fee schedules for the funds appear below.

For each fund with a stepped fee schedule, the schedules by which the unified management fee is determined are as follows:

Fund	Class	Percentage of Strategy Assets
Emerging Markets	Investor, A, C and R	1.850% of first $250 million 1.750% of the next $250 million 1.500% of the next $500 million 1.250% over $1 billion

The management fee schedule for the funds without a stepped fee schedule are as follows:

Emerging Markets Small Cap	Investor, A, C and R	1.60%
	Institutional	1.40%
	R6	1.25%

	R6	1.15%

	R6	1.12%

On each calendar day, each class of each fund accrues a management fee that is equal to the class’s management fee rate (as calculated pursuant to the above schedules) times the net assets of the class divided by 365 (366 in leap years). On the first business day of each month, the funds pay a management fee to the advisor for the previous month. The management fee is the sum of the daily fee calculations for each day of the previous month.

The management agreement between the corporation and the advisor shall continue in effect for a period of two years from its effective date (unless sooner terminated in accordance with its terms) and shall continue in effect from year to year thereafter for each fund so long as such continuance is approved at least annually by

(1) either the funds’ Board of Directors, or a majority of the outstanding voting securities of such fund (as defined in the Investment Company Act) and

(2) the vote of a majority of the directors of the funds who are not parties to the agreement or interested persons of the advisor, cast in person at a meeting called for the purpose of voting on such approval.

The management agreement states that the funds’ Board of Directors or a majority of the outstanding voting securities of each class of such fund may terminate the management agreement at any time without payment of any penalty on 60 days’ written notice to the advisor. The management agreement shall be automatically terminated if it is assigned.

The management agreement states that the advisor shall not be liable to the funds or their shareholders for anything other than willful misfeasance, bad faith, gross negligence or reckless disregard of its obligations and duties.

The management agreement also provides that the advisor and its officers, directors and employees may engage in other business, render services to others, and devote time and attention to any other business whether of a similar or dissimilar nature.

33

Certain investments may be appropriate for the funds and also for other clients advised by the advisor. Investment decisions for the funds and other clients are made with a view to achieving their respective investment objectives after consideration of such factors as their current holdings, availability of cash for investment and the size of their investment generally. A particular security may be bought or sold for only one client or fund, or in different amounts and at different times for more than one but less than all clients or funds. A particular security may be bought for one client or fund on the same day it is sold for another client or fund, and a client or fund may hold a short position in a particular security at the same time another client or fund holds a long position. In addition, purchases or sales of the same security may be made for two or more clients or funds on the same date. The advisor has adopted procedures designed to ensure such transactions will be allocated among clients and funds in a manner believed by the advisor to be equitable to each. In some cases this procedure could have an adverse effect on the price or amount of the securities purchased or sold by a fund.

The advisor may aggregate purchase and sale orders of the funds with purchase and sale orders of its other clients when the advisor believes that such aggregation provides the best execution for the funds. The Board of Directors has approved the policy of the advisor with respect to the aggregation of portfolio transactions. To the extent equity trades are aggregated, shares purchased or sold are generally allocated to the participating portfolios pro rata based on order size. The advisor will not aggregate portfolio transactions of the funds unless it believes such aggregation is consistent with its duty to seek best execution on behalf of the funds and the terms of the management agreement. The advisor receives no additional compensation or remuneration as a result of such aggregation.

Unified management fees incurred by each fund for the fiscal periods ended November 30, [2015], 2014 and 2013, are indicated in the following table. Because Emerging Markets Small Cap, Focused International Growth and Global Small Cap are new, they are not included.

Potential Conflicts of Interest

Certain conflicts of interest may arise in connection with the management of multiple portfolios. Potential conflicts include, for example, conflicts among investment strategies, such as one portfolio buying or selling a security while another portfolio has a differing, potentially opposite position in such security. This may include one portfolio taking a short position in the security of an issuer that is held long in another portfolio (or vice versa). Other potential conflicts may arise with respect to the allocation of investment opportunities, which are discussed in more detail below. American Century Investments has adopted policies and procedures that are designed to minimize the effects of these conflicts.

Responsibility for managing American Century Investments client portfolios is organized according to investment discipline. Investment disciplines include, for example, disciplined equity, U. S. growth mid- and small-cap, U.S. growth large-cap, value, global and non-U.S., fixed income, and asset allocation. Within each discipline are one or more portfolio teams responsible for managing specific client portfolios. Generally, client portfolios with similar strategies are managed by the same team using the same objective, approach, and philosophy. Accordingly, portfolio holdings, position sizes, and industry and sector exposures tend to be similar across similar portfolios, which minimizes the potential for conflicts of interest. In addition, American Century Investments maintains an ethical wall around each of its equity investment disciplines (U.S. growth large-cap, U.S. Growth mid- and small-cap, value, disciplined equity and global and non-U.S.), meaning that access to information regarding any portfolio’s transactional activities is only available to team members of the investment discipline that manages such portfolio. The ethical wall is intended to aid in preventing the misuse of portfolio holdings information and trading activity in the other disciplines.

For each investment strategy, one portfolio is generally designated as the “policy portfolio.” Other portfolios with similar investment objectives, guidelines and restrictions, if any, are referred to as “tracking portfolios.” When managing policy and tracking portfolios, a portfolio team typically purchases and sells securities across all portfolios that the team manages. American Century Investments’ trading systems include various order entry programs that assist in the management of multiple portfolios, such as the ability to purchase or sell the same relative amount of one security across several funds. In some cases a tracking portfolio may have additional restrictions or limitations that cause it to be managed separately from the policy portfolio. Portfolio managers make purchase and sale decisions for such portfolios alongside the policy portfolio to the extent the overlap is appropriate, and separately, if the overlap is not.

American Century Investments may aggregate orders to purchase or sell the same security for multiple portfolios when it believes such aggregation is consistent with its duty to seek best execution on behalf of its clients. Orders of certain client portfolios may, by investment restriction or otherwise, be determined not available for aggregation. American Century Investments has adopted policies and procedures to minimize the risk that a client portfolio could be systematically advantaged or disadvantaged in connection with the aggregation of orders. To the extent equity trades are aggregated, shares purchased or sold are generally allocated to the participating portfolios pro rata based on order size. Because initial public offerings (IPOs) are usually available in limited supply and in amounts too small to permit across-the-board pro rata allocations, American Century Investments has adopted special procedures designed to promote a fair and equitable allocation of IPO securities among clients over time. Fixed income securities transactions are not executed through a centralized trading desk. Instead, portfolio teams are responsible for executing trades with broker/dealers in a predominantly dealer marketplace. Trade allocation decisions are made by the portfolio manager at the time of trade execution and orders entered on the fixed income order management system.

Finally, investment of American Century Investments’ corporate assets in proprietary accounts may raise additional conflicts of interest. To mitigate these potential conflicts of interest, American Century Investments has adopted policies and procedures intended to provide that trading in proprietary accounts is performed in a manner that does not give improper advantage to American Century Investments to the detriment of client portfolios.

Compensation

American Century Investments portfolio manager compensation is structured to align the interests of portfolio managers with those of the shareholders whose assets they manage. As of November 30, [2015,] it includes the components described below, each of which is determined with reference to a number of factors such as overall performance, market competition, and internal equity.

Base Salary

Portfolio managers receive base pay in the form of a fixed annual salary.

Bonus

A significant portion of portfolio manager compensation takes the form of an annual incentive bonus tied to performance. Bonus payments are determined by a combination of factors. One factor is fund investment performance. Fund investment performance is generally measured by a combination of one-, three- and five-year pre-tax performance relative to various benchmarks and/or internally-customized peer groups, such as those indicated below. The performance comparison periods may be adjusted based on a fund’s inception date or a portfolio manager’s tenure on the fund. [As new funds, Emerging Markets Small Cap, Focused International Growth and Global Small Cap’s performance are not considered in determining portfolio manager compensation for 2015.]

¹  Custom peer groups are constructed using all the funds in the indicated categories as a starting point. Funds are then eliminated from the peer group based on a standardized methodology designed to result in a final peer group that is both more stable (i.e., has less peer turnover) over the long term and that more closely represents the fund’s true peers based on internal investment mandates.

²  The fund’s performance is not separately considered in determining portfolio manager compensation.

Portfolio managers may have responsibility for multiple American Century Investments mutual funds. In such cases, the performance of each is assigned a percentage weight appropriate for the portfolio manager’s relative levels of responsibility. Portfolio managers also may have responsibility for other types of similarly managed portfolios. If the performance of a similarly managed account is considered for purposes of compensation, it is measured in the same way as a comparable American Century Investments mutual fund (i.e., relative to the performance of a benchmark and/or peer group).

A second factor in the bonus calculation relates to the performance of a number of American Century Investments funds managed according to one of the following investment disciplines: U.S. growth, U.S. value, global and non-U.S., disciplined equity, fixed-income and asset allocation. Performance is measured for each product individually as described above and then combined to create an overall composite for the product group. These composites may measure one-year performance (equal weighted) or a combination of one-, three- and five-year performance (equal or asset weighted) depending on the portfolio manager’s responsibilities and products managed. This feature is designed to encourage effective teamwork among portfolio management teams in achieving long-term investment success for similarly styled portfolios.

A portion of portfolio managers’ bonuses may be tied to individual performance goals, such as research projects and the development of new products.

Restricted Stock Plans

Portfolio managers are eligible for grants of restricted stock of ACC. These grants are discretionary, and eligibility and availability can vary from year to year. The size of an individual’s grant is determined by individual and product performance as well as other product-specific considerations such as profitability. Grants can appreciate/depreciate in value based on the performance of the ACC stock during the restriction period (generally three to four years).

Deferred Compensation Plans

Portfolio managers are eligible for grants of deferred compensation. These grants are used in very limited situations, primarily for retention purposes. Grants are fixed and can appreciate/depreciate in value based on the performance of the American Century Investments mutual funds in which the portfolio manager chooses to invest them.

Transfer Agent and Administrator

American Century Services, LLC (ACS), 4500 Main Street, Kansas City, Missouri 64111, serves as transfer agent and dividend-paying agent for the funds. It provides physical facilities, computer hardware and software and personnel, for the day-to-day administration of the funds and the advisor. The advisor pays ACS’s costs for serving as transfer agent and dividend-paying agent for the funds out of the advisor’s unified management fee. For a description of this fee and the terms of its payment, see the discussion under the caption Investment Advisor on page 31.

Proceeds from purchases of fund shares may pass through accounts maintained by the transfer agent at Commerce Bank, N.A. or UMB Bank, n.a. before being held at the fund’s custodian. Redemption proceeds also may pass from the custodian to the shareholder through such bank accounts.

From time to time, special services may be offered to shareholders who maintain higher share balances in our family of funds. These services may include the waiver of minimum investment requirements, expedited confirmation of shareholder transactions, newsletters and a team of personal representatives. Any expenses associated with these special services will be paid by the advisor.

Sub-Administrator

The advisor has entered into an Administration Agreement with State Street Bank and Trust Company (SSB) to provide certain fund accounting, fund financial reporting, tax and treasury/tax compliance services for the funds, including striking the daily net asset value for each fund. The advisor pays SSB a monthly fee as compensation for these services that is based on the total net assets of accounts in the American Century complex serviced by SSB. ACS does pay SSB for some additional services on a per fund basis. While ACS continues to serve as the administrator of the funds, SSB provides sub-administrative services that were previously undertaken by ACS.

Distributor

The funds’ shares are distributed by American Century Investment Services, Inc. (ACIS), a registered broker-dealer. The distributor is a wholly owned subsidiary of ACC and its principal business address is 4500 Main Street, Kansas City, Missouri 64111.

The distributor is the principal underwriter of the funds’ shares. The distributor makes a continuous, best efforts underwriting of the funds’ shares. This means the distributor has no liability for unsold shares. The advisor pays ACIS’s costs for serving as principal underwriter of the funds’ shares out of the advisor’s unified management fee. For a description of this fee and the terms of its payment, see the discussion under the caption Investment Advisor on page 31. ACIS does not earn commissions for distributing the funds’ shares.

Certain financial intermediaries unaffiliated with the distributor or the funds may perform various administrative and shareholder services for their clients who are invested in the funds. These services may include assisting with fund purchases, redemptions and exchanges, distributing information about the funds and their performance, preparing and distributing client account statements, and other administrative and shareholder services that would otherwise be provided by the distributor or its affiliates. The distributor may pay fees out of its own resources to such financial intermediaries for providing these services.

Custodian Bank

State Street Bank and Trust Company (SSB), State Street Financial Center, One Lincoln Street, Boston, Massachusetts 02111 serves as custodian of the funds’ cash and securities. Foreign securities, if any, are held by foreign banks participating in a network coordinated by SSB. The custodian takes no part in determining the investment policies of the funds or in deciding which securities are purchased or sold by the funds. The funds, however, may invest in certain obligations of the custodian and may purchase or sell certain securities from or to the custodian.

Independent Registered Public Accounting Firm

Deloitte & Touche LLP is the independent registered public accounting firm of the funds. The address of Deloitte & Touche LLP is 1100 Walnut Street, Kansas City, Missouri 64106. As the independent registered public accounting firm of the funds, Deloitte & Touche LLP provides services including auditing the annual financial statements and financial highlights for each fund.

39

Brokerage Allocation

The advisor places orders for equity portfolio transactions with broker-dealers, who receive commissions for their services. Generally, commissions relating to securities traded on foreign exchanges will be higher than commissions relating to securities traded on U.S. exchanges. The advisor purchases and sells fixed-income securities through principal transactions, meaning the advisor normally purchases securities on a net basis directly from the issuer or a primary market-maker acting as principal for the securities. The funds generally do not pay a stated brokerage commission on these transactions, although the purchase price for debt securities usually includes an undisclosed compensation. Purchases of securities from underwriters typically include a commission or concession paid by the issuer to the underwriter, and purchases from dealers serving as market-makers typically include a dealer’s mark-up (i.e., a spread between the bid and asked prices).

Under the management agreement between the funds and the advisor, the advisor has the responsibility of selecting brokers and dealers to execute portfolio transactions. The funds’ policy is to secure the most favorable prices and execution of orders on its portfolio transactions. The advisor selects broker-dealers on their perceived ability to obtain “best execution” in effecting transactions in its clients’ portfolios. In selecting broker-dealers to effect portfolio transactions relating to equity securities, the advisor considers the full range and quality of a broker-dealer’s research and brokerage services, including, but not limited to, the following:

• applicable commission rates and other transaction costs charged by the broker-dealer

• value of research provided to the advisor by the broker-dealer (including economic forecasts, fundamental and technical advice on individual securities, market analysis, and advice, either directly or through publications or writings, as to the value of securities, availability of securities or of purchasers/sellers of securities)

• timeliness of the broker-dealer’s trade executions

• efficiency and accuracy of the broker-dealer’s clearance and settlement processes

• broker-dealer’s ability to provide data on securities executions

• financial condition of the broker-dealer

• the quality of the overall brokerage and customer service provided by the broker-dealer

In transactions to buy and sell fixed-income securities, the selection of the broker-dealer is determined by the availability of the desired security and its offering price, as well as the broker-dealer’s general execution and operational and financial capabilities in the type of transaction involved. The advisor will seek to obtain prompt execution of orders at the most favorable prices or yields. The advisor does not consider the receipt of products or services other than brokerage or research services in selecting broker-dealers. 

On an ongoing basis, the advisor seeks to determine what levels of commission rates are reasonable in the marketplace. In evaluating the reasonableness of commission rates, the advisor considers:

• rates quoted by broker-dealers

• the size of a particular transaction, in terms of the number of shares, dollar amount, and number of clients involved

• the ability of a broker-dealer to execute large trades while minimizing market impact

• the complexity of a particular transaction

• the nature and character of the markets on which a particular trade takes place

• the level and type of business done with a particular firm over a period of time

• the ability of a broker-dealer to provide anonymity while executing trades

• historical commission rates

• rates that other institutional investors are paying, based on publicly available information

The brokerage commissions paid by the funds may exceed those that another broker-dealer might have charged for effecting the same transactions, because of the value of the brokerage and research services provided by the broker-dealer. Research services furnished by broker-dealers through whom the funds effect securities transactions may be used by the advisor in servicing all of its accounts, and not all such services may be used by the advisor in managing the portfolios of the funds.

Pursuant to its internal allocation procedures, the advisor regularly evaluates the brokerage and research services provided by each broker-dealer that it uses. On a semi-annual basis, each member of the advisor’s portfolio management team rates the quality of research and brokerage services provided by each broker-dealer that provides execution services and research to the advisor for its clients’ accounts. The resulting scores are used to rank these broker-dealers on a broker research list. In the event that the advisor has determined that best execution for a particular transaction may be obtained by more than one broker-dealer, the advisor may consider the relative positions of the broker-dealer on this list in determining the party through which to execute the transaction. Actual business received by any firm may be more or less than other broker-dealers with a similar rank. Execution-only brokers are used where deemed appropriate.

In the fiscal years ended November 30, 2015, 2014 and 2013, the brokerage commissions including, as applicable, futures commissions, of each fund are listed in the following table. Because Emerging Markets Small Cap, Focused International Growth and Global Small Cap are new, they are not included.

¹ For the period March 19, 2015, the funds’ inception date, to November 15, 2015.

Brokerage commissions paid by a fund may vary significantly from year to year as a result of changing asset levels throughout the year, portfolio turnover, varying market conditions, and other factors. The increase in brokerage commissions paid by Global Growth, International Opportunities, NT Emerging Markets and NT International Growth over the last three fiscal years is due to increases in the net assets of the funds. The decrease in brokerage commissions paid by International Discovery over the last three fiscal years is due to decreases in net assets of the fund.

Regular Broker-Dealers

As of the end of its most recently completed fiscal year, each of the funds listed below owned securities of its regular brokers or dealers (as defined by Rule 10b-1 under the Investment Company Act of 1940) or of their parent companies.

Information About Fund Shares

Each of the funds named on the front of this statement of additional information is a series of shares issued by the corporation, and shares of each fund have equal voting rights. In addition, each series (or fund) may be divided into separate classes. See Multiple Class Structure, which follows. Additional funds and classes may be added without a shareholder vote.

Each fund votes separately on matters affecting that fund exclusively. Voting rights are not cumulative, so investors holding more than 50% of the corporation’s (all funds’) outstanding shares may be able to elect a Board of Directors. The corporation undertakes dollar-based voting, meaning that the number of votes a shareholder is entitled to is based upon the dollar amount of the shareholder’s investment. The election of directors is determined by the votes received from all the corporation’s shareholders without regard to whether a majority of shares of any one fund voted in favor of a particular nominee or all nominees as a group.

The assets belonging to each series are held separately by the custodian and the shares of each series represent a beneficial interest in the principal, earnings and profit (or losses) of investment and other assets held for each series. Within their respective series, all shares have equal redemption rights. Each share, when issued, is fully paid and non-assessable.

Each shareholder has rights to dividends and distributions declared by the fund he or she owns and to the net assets of such fund upon its liquidation or dissolution proportionate to his or her share ownership interest in the fund.

Multiple Class Structure

The corporation’s Board of Directors has adopted a multiple class plan pursuant to Rule 18f-3 adopted by the SEC. The plan is described in the prospectus of any fund that offers more than one class. Pursuant to such plan, the funds may issue the following classes of shares: Investor Class, Institutional Class, A Class, C Class, R Class and R6 Class. Not all funds offer all classes.

Shares of the NT funds are only available for purchase by certain fund of funds advised by American Century Investments. Shares of all other funds are available as follows. The Investor Class is made available to investors directly from American Century Investments and/or through some financial intermediaries. Investor Class shares charge a single unified management fee, without any load or commission payable to American Century Investments. Additional information regarding eligibility for Investor Class shares may be found in the funds’ prospectuses. The Institutional Class is made available to institutional shareholders or through financial intermediaries that provide various shareholder and administrative services. The R6 Class is generally available only to participants in employer-sponsored retirement plans where a financial intermediary provides recordkeeping services to plan participants. Because Institutional Class and R6 Class shareholders do not require the same level of shareholder and administrative services from the advisor as Investor Class shareholders, and because American Century does not pay any service, distribution or administrative fees to financial intermediaries for R6 Class shares, the advisor is able to charge these classes lower total management fees. The A and C Classes also are made available through financial intermediaries, for purchase by individual investors who receive advisory and personal services from the intermediary. The R Class is made available through financial intermediaries and is generally used in 401(k) and other retirement plans. The unified management fee for the A, C and R Classes is the same as for Investor Class, but the A, C and R Class shares each are subject to a separate Master Distribution and Individual Shareholder Services Plan (the A Class Plan, C Class Plan and R Class Plan, respectively, and collectively, the plans) described below. The plans have been adopted by the funds’ Board of Directors in accordance with Rule 12b-1 adopted by the SEC under the Investment Company Act.

Rule 12b-1

Rule 12b-1 permits an investment company to pay expenses associated with the distribution of its shares in accordance with a plan adopted by its Board of Directors and approved by its shareholders. Pursuant to such rule, the Board of Directors of the funds’ A, C and R Classes have approved and entered into the A Class Plan, C Class Plan and R Class Plan, respectively. The plans are described below.

In adopting the plans, the Board of Directors (including a majority of directors who are not interested persons of the funds, as defined in the Investment Company Act, hereafter referred to as the independent directors) determined that there was a reasonable likelihood that the plans would benefit the funds and the shareholders of the affected class. Some of the anticipated benefits include improved name recognition of the funds generally; and growing assets in existing funds, which helps retain and attract investment management talent, provides a better environment for improving fund performance, and can lower the total expense ratio for funds with stepped-fee schedules.

Pursuant to Rule 12b-1, information about revenues and expenses under the plans is presented to the Board of Directors quarterly. Continuance of the plans must be approved by the Board of Directors, including a majority of the independent directors, annually. The plans may be amended by a vote of the Board of Directors, including a majority of the independent directors, except that the plans may not be amended to materially increase the amount spent for distribution without majority approval of the shareholders of the affected class. The plans terminate automatically in the event of an assignment and may be terminated upon a vote of a majority of the independent directors or by a majority of the outstanding shareholder votes of the affected class.

All fees paid under the plans will be made in accordance with Section 2830 of the Conduct Rules of the Financial Industry Regulatory Authority (FINRA).

The Share Class Plans

As described in the prospectuses, the A, C and R Class shares of the funds are made available to participants in employer-sponsored retirement plans and to persons purchasing through broker-dealers, banks, insurance companies and other financial intermediaries that provide various administrative, shareholder and distribution services. The funds’ distributor enters into contracts with various banks, broker-dealers, insurance companies and other financial intermediaries, with respect to the sale of the funds’ shares and/or the use of the funds’ shares in various investment products or in connection with various financial services.

Certain recordkeeping and administrative services that would otherwise be performed by the funds’ transfer agent may be performed by a plan sponsor (or its agents) or by a financial intermediary for A, C and R Class investors. In addition to such services, the financial intermediaries provide various individual shareholder and distribution services.

To enable the funds’ shares to be made available through such plans and financial intermediaries, and to compensate them for such services, the funds’ Board of Directors has adopted the A, C and R Class Plans. Pursuant to the plans, the following fees are paid and described further below.

A Class

The A Class pays the funds’ distributor 0.25% annually of the average daily net asset value of the A Class shares. The distributor may use these fees to pay for certain ongoing shareholder and administrative services and for distribution services, including past distribution services. This payment is fixed at 0.25% and is not based on expenses incurred by the distributor.

C Class

The C Class pays the funds’ distributor 1.00% annually of the average daily net asset value of the funds’ C Class shares, 0.25% of which is paid for certain ongoing individual shareholder and administrative services and 0.75% of which is paid for distribution services, including past distribution services. This payment is fixed at 1.00% and is not based on expenses incurred by the distributor.

R Class

The R Class pays the funds’ distributor 0.50% annually of the average daily net asset value of the R Class shares. The distributor may use these fees to pay for certain ongoing shareholder and administrative services and for distribution services, including past distribution services. This payment is fixed at 0.50% and is not based on expenses incurred by the distributor.

During the fiscal year ended November 30, [2015], the aggregate amount of fees paid under each class plan was:

	A Class	C Class	R Class
Emerging Markets
Global Growth
International Discovery
International Growth
International Opportunities
International Value

The distributor then makes these payments to the financial intermediaries (including underwriters and broker-dealers, who may use some of the proceeds to compensate sales personnel) who offer the A, C and R Class shares for the services described below. No portion of these payments is used by the distributor to pay for advertising, printing costs or interest expenses.

Payments may be made for a variety of individual shareholder services, including, but not limited to:

(a) providing individualized and customized investment advisory services, including the consideration of shareholder profiles and specific goals;

(b) creating investment models and asset allocation models for use by shareholders in selecting appropriate funds;

(c) conducting proprietary research about investment choices and the market in general;

(d) periodic rebalancing of shareholder accounts to ensure compliance with the selected asset allocation;

(e) consolidating shareholder accounts in one place;

(f) paying service fees for providing personal, continuing services to investors, as contemplated by the Conduct Rules of FINRA; and

(g) other individual services.

Individual shareholder services do not include those activities and expenses that are primarily intended to result in the sale of additional shares of the funds.

43

Distribution services include any activity undertaken or expense incurred that is primarily intended to result in the sale of A, C, R and/or Advisor Class shares, which services may include but are not limited to:

(a) paying sales commissions, on-going commissions and other payments to brokers, dealers, financial institutions or others who sell A, C and R Class shares pursuant to selling agreements;

(b) compensating registered representatives or other employees of the distributor who engage in or support distribution of the funds’ A, C and R Class shares;

(c) compensating and paying expenses (including overhead and telephone expenses) of the distributor;

(d) printing prospectuses, statements of additional information and reports for other-than-existing shareholders;

(e) preparing, printing and distributing sales literature and advertising materials provided to the funds’ shareholders and prospective shareholders;

(f) receiving and answering correspondence from prospective shareholders, including distributing prospectuses, statements of additional information, and shareholder reports;

(g) providing facilities to answer questions from prospective shareholders about fund shares;

(h) complying with federal and state securities laws pertaining to the sale of fund shares;

(i) assisting shareholders in completing application forms and selecting dividend and other account options;

(j) providing other reasonable assistance in connection with the distribution of fund shares;

(k) organizing and conducting sales seminars and payments in the form of transactional and compensation or promotional incentives;

(l) profit on the foregoing; and

(m) such other distribution and services activities as the advisor determines may be paid for by the funds pursuantto the terms of the agreement between the corporation and the funds’ distributor and in accordance with Rule 12b-1 of the Investment Company Act.

Valuation of a Fund’s Securities

The net asset value (NAV) for each class of each fund is calculated by adding the value of all portfolio securities and other assets attributable to the class, deducting liabilities, and dividing the result by the number of shares of the class outstanding. Expenses and interest earned on portfolio securities are accrued daily.

All classes of the funds except the A Class are offered at their NAV. The A Class of the funds are offered at its public offering price, which is the net asset value plus the appropriate sales charge. This calculation may be expressed as a formula:

Offering Price = NAV/(1 – Sales Charge as a % of Offering Price)

For example, if the NAV of a fund’s A Class shares is $5.00, the public offering price would be $5.00/(1-5.75%) = $5.31.

Each fund’s NAV is calculated as of the close of business of the New York Stock Exchange (the NYSE), each day the NYSE is open for business. The NYSE usually closes at 4 p.m. Eastern time. The NYSE typically observes the following holidays: New Year’s Day, Martin Luther King Jr. Day, Presidents’ Day, Good Friday, Memorial Day, Independence Day, Labor Day, Thanksgiving Day and Christmas Day. Although the funds expect the same holiday schedule to be observed in the future, the NYSE may modify its holiday schedule at any time.

The portfolio securities of each fund that are listed or traded on a domestic securities exchange are valued at the last sale price on that exchange except as otherwise noted. Portfolio securities primarily traded on foreign securities exchanges are generally valued at the preceding closing values of such securities on the exchange where primarily traded or as of the close of the NYSE, if that is earlier. That value is then converted to U.S. dollars at the prevailing foreign exchange rate. If no sale is reported, or if local convention or regulation so provides, the mean of the latest bid and asked prices is used. Depending on local convention or regulation, securities traded over-the-counter are priced at the mean of the latest bid and asked prices, the last sale price or the official closing price. When market quotations are not readily available, securities and other assets are valued at fair value as determined in accordance with procedures adopted by the Board of Directors.

Debt securities not traded on a principal securities exchange are valued through valuations obtained from a commercial pricing service or at the most recent mean of the bid and asked prices provided by investment dealers in accordance with procedures established by the Board of Directors.

Securities maturing within 60 days of the valuation date may be valued at cost, plus or minus any amortized discount or premium, unless the directors determine that this would not result in fair valuation of a given security. Other assets and securities for which quotations are not readily available are valued in good faith using methods approved by the Board of Directors.

The value of an exchange-traded foreign security is determined in its national currency as of the close of trading on the foreign exchange on which it is traded or as of the close of business on the NYSE, if that is earlier. That value is then translated to dollars at the prevailing foreign exchange rate.

44

Trading in securities on European and Far Eastern securities exchanges and over-the-counter markets is normally completed at various times before the close of business on each day that the NYSE is open. If an event were to occur after the value of a security was established but before the NAV was determined that was likely to materially change the NAV, then that security would be valued as determined in accordance with procedures adopted by the Board of Directors.

Trading of these securities in foreign markets may not take place on every day that the NYSE is open. In addition, trading may take place in various foreign markets and on some electronic trading networks on Saturdays or on other days when the NYSE is not open and on which the funds’ NAVs are not calculated. Therefore, such calculations do not take place contemporaneously with the determination of the prices of many of the portfolio securities used in such calculations and the value of the funds’ portfolios may be affected on days when shares of the fund may not be purchased or redeemed.

45

Taxes

Federal Income Taxes

Each fund intends to qualify annually as a regulated investment company (RIC) under Subchapter M of the Internal Revenue Code of 1986, as amended (the Code). RICs generally are not subject to federal and state income taxes. To qualify as a RIC a fund must, among other requirements, distribute substantially all of its net investment income and net realized capital gains (if any) to investors each year. If a fund were not eligible to be treated as a RIC, it would be liable for taxes at the fund level on all its income, significantly reducing its distributions to investors and eliminating investors’ ability to treat distributions received from the fund in the same manner in which they were realized by the fund. Under certain circumstances, the Code allows funds to cure deficiencies that would otherwise result in the loss of RIC status, including by paying a fund-level tax.

To qualify as a RIC, a fund must meet certain requirements of the Code, among which are requirements relating to sources of its income and diversification of its assets. A fund is also required to distribute 90% of its investment company taxable income each year. Additionally, a fund must declare dividends by December 31 of each year equal to at least 98% of ordinary income (as of December 31) and 98.2% of capital gains (as of October 31) to avoid the nondeductible 4% federal excise tax on any undistributed amounts.

A fund’s transactions in foreign currencies, forward contracts, options and futures contracts (including options and futures contracts on foreign currencies) will be subject to special provisions of the Code that, among other things, may affect the character of gains and losses realized by the fund (i.e., may affect whether gains or losses are ordinary or capital), accelerate recognition of income to the fund, defer fund losses, and affect the determination of whether capital gains and losses are characterized as long-term or short-term capital gains or losses. These rules could therefore affect the character, amount and timing of distributions to shareholders. These provisions also may require a fund to mark-to-market certain types of the positions in its portfolio (i.e., treat them as if they were sold), which may cause the fund to recognize income without receiving cash with which to make distributions in amounts necessary to satisfy the distribution requirements of the Code for relief from income and excise taxes. A fund will monitor its transactions and may make such tax elections as fund management deems appropriate with respect to these transactions.

A fund’s investments in foreign securities may be subject to withholding and other taxes imposed by foreign countries. However, tax conventions between certain countries and the United States may reduce or eliminate such taxes. Any foreign taxes paid by a fund will reduce its dividend distributions to investors.

If more than 50% of the value of a fund’s total assets at the end of its fiscal year consists of securities of foreign corporations, the fund may make an election with the Internal Revenue Service with respect to such fiscal year so that fund shareholders may be able to claim a foreign tax credit. If such an election is made, the eligible foreign taxes will be treated as income received by you. In order for you to utilize the foreign tax credit, you must have held your shares for 16 days or more during the 31-day period, beginning 15 days prior to the ex-dividend date for the mutual fund shares. The mutual fund must meet a similar holding period requirement with respect to securities to which a dividend is attributable. Any portion of the foreign tax credit that is ineligible as a result of the fund not meeting the holding period requirement will be deducted in computing net investment income.

If a fund purchases the securities of certain foreign investment entities called passive foreign investment companies (PFIC), capital gains on the sale of such holdings will be deemed ordinary income regardless of how long the fund holds the investment. The fund also may be subject to corporate income tax and an interest charge on certain dividends and capital gains earned from these investments, regardless of whether such income and gains are distributed to the fund. To avoid such tax and interest, the fund may elect to treat PFICs as sold on the last day of its fiscal year, mark-to-market these securities, and recognize any unrealized gains (or losses, to the extent of previously recognized gains) as ordinary income each year.

As of November 30, [2015], the funds in the table below had the following capital loss carryovers, which expire in the years and amounts listed. When a fund has a capital loss carryover, it does not make capital gains distributions until the loss has been offset or expired. The Regulated Investment Company Modernization Act of 2010 allows the funds to carry forward capital losses incurred in future taxable years for an unlimited period. However, any losses incurred during those future taxable years will be required to be utilized prior to the losses which carry an expiration date. As a result, capital loss carryforwards may be more likely to expire unused. Because Emerging Markets Small Cap, Focused International Growth and Global Small Cap are new, they are not included.

If you have not complied with certain provisions of the Internal Revenue Code and Regulations, either American Century Investments or your financial intermediary is required by federal law to withhold and remit to the IRS the applicable federal withholding rate of reportable payments (which may include dividends, capital gains distributions and redemption proceeds). Those regulations require you to certify that the Social Security number or tax identification number you provide is correct and that you are not subject to withholding for previous under-reporting to the IRS. You will be asked to make the appropriate certification on your account application. Payments reported by us to the IRS that omit your Social Security number or tax identification number will subject us to a non-refundable penalty of $50, which will be charged against your account if you fail to provide the certification by the time the report is filed.

If fund shares are purchased through taxable accounts, distributions of either cash or additional shares of net investment income and net short-term capital gains are taxable to you as ordinary income, unless they are designated as qualified dividend income and you meet a minimum required holding period with respect to your shares of a fund, in which case such distributions are taxed at the same rate as long-term capital gains. Qualified dividend income is a dividend received by a fund from the stock of a domestic or qualifying foreign corporation, provided that the fund has held the stock for a required holding period. The required holding period for qualified dividend income is met if the underlying shares are held more than 60 days in the 121-day period beginning 60 days prior to the ex-dividend date. Dividends received by the funds on shares of stock of domestic corporations may qualify for the 70% dividends-received deduction when distributed to corporate shareholders to the extent that the fund held those shares for more than 45 days.

Distributions from gains on assets held by a fund longer than 12 months are taxable as long-term gains regardless of the length of time you have held your shares in the fund. If you purchase shares in the fund and sell them at a loss within six months, your loss on the sale of those shares will be treated as a long-term capital loss to the extent of any long-term capital gains dividend you received on those shares.

A redemption of shares of a fund (including a redemption made in an exchange transaction) will be a taxable transaction for federal income tax purposes and you will generally recognize gain or loss in an amount equal to the difference between the basis of the shares and the amount received. If a loss is realized on the redemption of fund shares, the reinvestment in additional fund shares within 30 days before or after the redemption may be subject to the “wash sale” rules of the Code, resulting in a postponement of the recognition of such loss for federal income tax purposes.

A 3.8% Medicare contribution tax is imposed on net investment income, including interest, dividends and capital gains, provided you meet specified income levels.

State and Local Taxes

Distributions by the funds also may be subject to state and local taxes, even if all or a substantial part of such distributions are derived from interest on U.S. government obligations which, if you received such interest directly, would be exempt from state income tax. However, most but not all states allow this tax exemption to pass through to fund shareholders when a fund pays distributions to its shareholders. You should consult your tax advisor about the tax status of such distributions in your state.

The information above is only a summary of some of the tax considerations affecting the funds and their U.S. shareholders. No attempt has been made to discuss individual tax consequences. A prospective investor should consult with his or her tax advisors or state or local tax authorities to determine whether the funds are suitable investments.

Financial Statements

Emerging Markets Small Cap, Focused International Growth and Global Small Cap do not have financial statements or financial highlights because they are new. The other fund’s financial statements and financial highlights for the fiscal year ended November 30, 2015 have been audited by Deloitte & Touche LLP, independent registered public accounting firm. The Reports of Independent Registered Public Accounting Firm and the financial statements included in the annual reports of each of these funds for the fiscal year ended November 30, 2015, are incorporated herein by reference.

The funds are unaware of any other shareholders, beneficial or of record, who own more than 5% of any class of a fund’s outstanding shares or who own more than 25% of the voting securities of the corporation. A shareholder owning beneficially more than 25% of the corporation’s outstanding shares may be considered a controlling person. The vote of any such person could have a more significant effect on matters presented at a shareholders’ meeting than votes of other shareholders. As of [March 1, 2015, the officers and directors of the funds, as a group, owned 5% of the R6 Class of Emerging Markets, 3% of the R6 Class of Global Growth, 3% of the Institutional Class of International Discovery, 6% of the R6 Class of International Growth, 6% of the R6 Class of International Value and less than 1% of all other classes of the other funds’ outstanding shares.]

Appendix B – Sales Charges and Payments to Dealers

Sales Charges

The sales charges applicable to the A and C Classes of the funds are described in the prospectuses for those classes in the section titled Investing Through a Financial Intermediary. Shares of the A Class are subject to an initial sales charge, which declines as the amount of the purchase increases. Additional information regarding reductions and waivers of the A Class sales charge may be found in the funds’ prospectuses. Shares of the A and C Classes are subject to a contingent deferred sales charge (CDSC) upon redemption of the shares in certain circumstances. The specific charges and when they apply are described in the relevant prospectuses. The CDSC may be waived for certain redemptions by some shareholders, as described in the prospectuses.

An investor may terminate his relationship with an intermediary at any time. If the investor does not establish a relationship with a new intermediary and transfer any accounts to that new intermediary, such accounts may be exchanged to the Investor Class of the fund, if such class is available. The investor will be the shareholder of record of such accounts. In this situation, any applicable CDSCs will be charged when the exchange is made.

The aggregate CDSCs paid to the distributor for A Class shares in the fiscal year ended November 30, [2015], were:

Global Growth

The aggregate CDSCs paid to the distributor for C Class shares in the fiscal year ended November 30, [2015], were:

Emerging Markets

Global Growth

International Discovery

International Growth

International Opportunities

International Value

[Because Emerging Markets Small Cap, Focused International Growth and Global Small Cap are new, they are not included.]

Payments to Dealers

The funds’ distributor expects to pay dealer commissions to the financial intermediaries who sell A and/or C Class shares of the fund at the time of such sales. Payments for A Class shares will be as follows:

Purchase Amount	Dealer Commission as a % of Offering Price
< $50,000	5.00%
$50,000 - $99,999	4.00%
$100,000 - $249,999	3.25%
$250,000 - $499,999	2.00%
$500,000 - $999,999	1.75%
$1,000,000 - $3,999,999	1.00%
$4,000,000 - $9,999,999	0.50%
> $10,000,000	0.25%

No dealer commission will be paid on purchases by employer-sponsored retirement plans. For this purpose, employer-sponsored retirement plans do not include SEP IRAs, SIMPLE IRAs or SARSEPs. Payments will equal 1.00% of the purchase price of the C Class shares sold by the financial intermediary. The distributor will retain the 12b-1 fee paid by the C Class of funds for the first 12 months after the shares are purchased. This fee is intended in part to permit the distributor to recoup a portion of on-going sales commissions to dealers plus financing costs, if any. Beginning with the first day of the 13th month, the distributor will make the C Class distribution and individual shareholder services fee payments described above to the financial intermediaries involved on a quarterly basis. In addition, C Class purchases and A Class purchases greater than $1,000,000 are subject to a CDSC as described in the prospectuses.

From time to time, the distributor may make additional payments to dealers, including but not limited to payment assistance for conferences and seminars, provision of sales or training programs for dealer employees and/or the public (including, in some cases, payment for travel expenses for registered representatives and other dealer employees who participate), advertising and sales campaigns about a fund or funds, and assistance in financing dealer-sponsored events. Other payments may be offered as well, and all such payments will be consistent with applicable law, including the then-current rules of the Financial Industry Regulatory Authority. Such payments will not change the price paid by investors for shares of the funds.

B-1

Appendix C – Buying and Selling Fund Shares

Information about buying, selling, exchanging and, if applicable, converting fund shares is contained in the funds’ prospectuses. The prospectuses are available to investors without charge and may be obtained by calling us.

Employer-Sponsored Retirement Plans

Certain group employer-sponsored retirement plans that hold a single account for all plan participants with the fund, or that are part of a retirement plan or platform offered by banks, broker-dealers, financial advisors or insurance companies, or serviced by retirement recordkeepers are eligible to purchase Investor, Institutional, A, C, R and R6 Class shares. A and C Class purchases are available at net asset value with no dealer commission paid to the financial professional and do not incur a CDSC. A, C and R Class shares purchased in employer-sponsored retirement plans are subject to applicable distribution and service (12b-1) fees, which the financial intermediary begins receiving immediately at the time of purchase. American Century 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. 

Examples of employer-sponsored retirement plans include the following:

• 401(a) plans

• pension plans

• profit sharing plans

• 401(k) plans (including plans with a Roth

401(k) feature, SIMPLE 401(k) plans and

Solo 401(k) plans)

• money purchase plans

• target benefit plans

• Taft-Hartley multi-employer pension plans

• SERP and “Top Hat” plans

• ERISA trusts

• employee benefit plans and trusts

• employer-sponsored health plans

• 457 plans

• KEOGH or HR(10) plans

• employer-sponsored 403(b) plans

(including plans with a Roth 403(b) feature)

• nonqualified deferred compensation plans

• nonqualified excess benefit plans

• nonqualified retirement plans

Traditional and Roth IRAs are not considered employer-sponsored retirement plans, and SIMPLE IRAs, SEP IRAs and SARSEPs are collectively referred to as Business IRAs. SEP IRA, SIMPLE IRA or SARSEP retirement plans that (i) held shares of an A Class fund prior to March 1, 2009 that received sales charge waivers or (ii) held shares of an Advisor Class fund that was renamed A Class on March 1, 2010, may permit additional purchases by new and existing participants in A Class shares without an initial sales charge.

R Class IRA Accounts established prior to August 1, 2006 may make additional purchases.

C-1

Waiver of Minimum Initial Investment Amounts — Institutional Class

A financial intermediary, upon receiving prior approval from American Century Investments, may waive applicable minimum initial investment amounts per shareholder for Institutional Class shares in the following situations:

• Broker-dealers purchasing fund shares for clients in broker-sponsored discretionary fee-based advisory programs where the portfolio manager of the program acts on behalf of the shareholder through omnibus accounts;

• Trust companies and bank wealth management organizations purchasing shares in a fiduciary, discretionary trustee or advisory account on behalf of the shareholder, through omnibus accounts or nominee name accounts;

• Financial intermediaries with clients of a registered investment advisor (RIA) purchasing fund shares in fee based advisory accounts with a $100,000 initial minimum per client or $250,000 aggregated initial investment across multiple clients, where the RIA is purchasing shares through certain broker-dealers through omnibus accounts;

• Qualified Tuition Programs under Section 529 that have entered into an agreement with the distributor; and

• Certain other situations deemed appropriate by American Century Investments.

Appendix D – Explanation of Fixed-Income Securities Ratings

As described in the prospectuses, the funds invest in fixed-income securities. Those investments, however, are subject to certain credit quality restrictions, as noted in the prospectuses and in this statement of additional information. The following is a summary of the rating categories referenced in the prospectus disclosure.

Ratings of Corporate Debt Securities
Standard & Poor’s Long-Term Issue Credit Ratings*
Category	Definition
AAA	An obligation rated ‘AAA’ has the highest rating assigned by Standard & Poor’s. The obligor’s capacity to meet its financial commitment on the obligation is extremely strong.
AA	An obligation rated ‘AA’ differs from the highest-rated obligations only to a small degree. The obligor’s capacity to meet its financial commitment on the obligation is very strong.
A	An obligation rated ‘A’ is somewhat more susceptible to the adverse effects of changes in circumstances and economic conditions than obligations in higher-rated categories. However, the obligor’s capacity to meet its financial commitment on the obligation is still strong.
BBB	An obligation rated ‘BBB’ exhibits adequate protection parameters. However, adverse economic conditions or changing circumstances are more likely to lead to a weakened capacity of the obligor to meet its financial commitment on the obligation.
BB;B; CCC; CC; and C	Obligations rated ‘BB’, ‘B’, ‘CCC’, ‘CC’, and ‘C’ are regarded as having significant speculative characteristics. ‘BB’ indicates the least degree of speculation and ‘C’ the highest. While such obligations will likely have some quality and protective characteristics, these may be outweighed by large uncertainties or major exposures to adverse conditions.
BB	An obligation rated ‘BB’ is less vulnerable to nonpayment than other speculative issues. However, it faces major ongoing uncertainties or exposure to adverse business, financial, or economic conditions which could lead to the obligor’s inadequate capacity to meet its financial commitment on the obligation.
B	An obligation rated ‘B’ is more vulnerable to nonpayment than obligations rated ‘BB’, but the obligor currently has the capacity to meet its financial commitment on the obligation. Adverse business, financial, or economic conditions will likely impair the obligor’s capacity or willingness to meet its financial commitment on the obligation.
CCC	An obligation rated ‘CCC’ is currently vulnerable to nonpayment, and is dependent upon favorable business, financial, and economic conditions for the obligor to meet its financial commitment on the obligation. In the event of adverse business, financial, or economic conditions, the obligor is not likely to have the capacity to meet its financial commitment on the obligation.
CC	An obligation rated ‘CC’ is currently highly vulnerable to nonpayment. The ‘CC’ rating is used when a default has not yet occurred, but Standard & Poor’s expects default to be a virtual certainty, regardless of the anticipated time to default.
C	An obligation rated ‘C’ is currently highly vulnerable to nonpayment,and the obligation is expected to have lower relative seniority or lower ultimate recovery compared to obligations that are rated higher.
D	An obligation rated ‘D’ is in default or in breach of an imputed promise. For non-hybrid capital instruments, the ‘D’ rating category is used when payments on an obligation are not made on the date due, unless Standard & Poor’s believes that such payments will be made within five business days in the absence of a stated grace period or within the earlier of the stated grace period or 30 calendar days. The ‘D’ rating also will be used upon the filing of a bankruptcy petition or the taking of similar action and where default on an obligation is a virtual certainty, for example due to automatic stay provisions. An obligation’s rating is lowered to ‘D’ if it is subject to a distressed exchange offer.
NR	This indicates that no rating has been requested, or that there is insufficient information on which to base a rating, or that Standard & Poor’s does not rate a particular obligation as a matter of policy.

*The ratings from “AA” to “CCC” may be modified by the addition of a plus (+) or minus (-) sign to show relative standing within the major rating categories.

D-1

Moody’s Investors Service, Inc. Global Long-Term Rating Scale
Category	Definition
Aaa	Obligations rated Aaa are judged to be of the highest quality, subject to the lowest level of credit risk.
Aa	Obligations rated Aa are judged to be of high quality and are subject to very low credit risk.
A	Obligations rated A are judged to be upper-medium grade and are subject to low credit risk.
Baa	Obligations rated Baa are judged to be medium-grade and subject to moderate credit risk and as such may possess certain speculative characteristics.
Ba	Obligations rated Ba are judged to be speculative and are subject to substantial credit risk.
B	Obligations rated B are considered speculative and are subject to high credit risk.
Caa	Obligations rated Caa are judged to be speculative of poor standing and are subject to very high credit risk.
Ca	Obligations rated Ca are highly speculative and are likely in, or very near, default, with some prospect of recovery of principal and interest.
C	Obligations rated C are the lowest rated and are typically in default, with little prospect for recovery of principal or interest.

Note: Moody’s appends numerical modifiers 1, 2, and 3 to each generic rating classification from Aa through Caa. The modifier 1 indicates that the obligation ranks in the higher end of its generic rating category; the modifier 2 indicates a mid-range ranking; and the modifier 3 indicates a ranking in the lower end of that generic rating category. Additionally, a “(hyb)” indicator is appended to all ratings of hybrid securities issued by banks, insurers, finance companies, and securities firms.

Fitch Investors Service, Inc. Long-Term Ratings
Category	Definition
AAA	Highest credit quality. ‘AAA’ ratings denote the lowest expectation of credit risk. They are assigned only in cases of exceptionally strong capacity for payment of financial commitments. This capacity is highly unlikely to be adversely affected by foreseeable events.
AA	High credit quality. ‘A’ ratings denote expectations of low credit risk. The capacity for payment of financial commitments is considered strong. This capacity may, nevertheless, be more vulnerable to adverse business or economic conditions than is the case for higher ratings.
A	High credit quality. ‘A’ ratings denote expectations of low credit risk. The capacity for payment of financial commitments is considered strong. This capacity may, nevertheless, be more vulnerable to adverse business or economic conditions than is the case for higher ratings.
BBB	Good credit quality. ‘BBB’ ratings indicate that expectations of credit risk are currently low. The capacity for payment of financial commitments is considered adequate but adverse business or economic conditions are more likely to impair this capacity.
BB	Speculative. ‘BB’ ratings indicate an elevated vulnerability to credit risk, particularly in the event of adverse changes in business or economic conditions over time; however, business or financial alternatives may be available to allow financial commitments to be met.
B	Highly speculative. ‘B’ ratings indicate that material credit risk is present.
CCC	Substantial credit risk. ‘CCC’ ratings indicate that substantial credit risk is present.
CC	Very high levels of credit risk. ‘CC’ ratings indicate very high levels of credit risk.
C	Exceptionally high levels of credit risk. ‘C’ indicates exceptionally high levels of credit risk.

Defaulted obligations typically are not assigned ‘RD’ or ‘D’ ratings, but are instead rated in the ‘B’ to ‘C’ rating categories, depending upon their recovery prospects and other relevant characteristics. This approach better aligns obligations that have comparable overall expected loss but varying vulnerability to default and loss.

D-2

Notes: The modifiers “+” or “-“ may be appended to a rating to denote relative status within major rating categories. Such suffixes are not added to the ‘AAA’ obligation rating category, or to corporate finance obligation ratings in the categories below ‘CCC’.

Standard & Poor’s Corporate Short-Term Note Ratings
Category	Definition
A-1	A short-term obligation rated ‘A-1’ is rated in the highest category by Standard & Poor’s. The obligor’s capacity to meet its financial commitment on the obligation is strong. Within this category, certain obligations are designated with a plus sign (+). This indicates that the obligor’s capacity to meet its financial commitment on these obligations is extremely strong.
A-2	A short-term obligation rated ‘A-2’ is somewhat more susceptible to the adverse effects of changes in circumstances and economic conditions than obligations in higher rating categories. However, the obligor’s capacity to meet its financial commitment on the obligation is satisfactory.
A-3	A short-term obligation rated ‘A-3’ exhibits adequate protection parameters. However, adverse economic conditions or changing circumstances are more likely to lead to a weakened capacity of the obligor to meet its financial commitment on the obligation.
B	A short-term obligation rated ‘B’ is regarded as vulnerable and has significant speculative characteristics. The obligor currently has the capacity to meet its financial commitments; however, it faces major ongoing uncertainties which could lead to the obligor’s inadequate capacity to meet its financial commitments.
C	A short-term obligation rated ‘C’ is currently vulnerable to nonpayment and is dependent upon favorable business, financial, and economic conditions for the obligor to meet its financial commitment on the obligation.
D	A short-term obligation rated ‘D’ is in default or in breach of an imputed promise. For non-hybrid capital instruments, the ‘D’ rating category is used when payments on an obligation are not made on the date due, unless Standard & Poor’s believes that such payments will be made within any stated grace period. However, any stated grace period longer than five business days will be treated as five business days. The ‘D’ rating also will be used upon the filing of a bankruptcy petition or the taking of a similar action and where default on an obligation is a virtual certainty, for example due to automatic stay provisions. An obligation’s rating is lowered to ‘D’ if it is subject to a distressed exchange offer.

Moody’s Global Short-Term Rating Scale
Category	Definition
P-1	Issuers (or supporting institutions) rated Prime-1 have a superior ability to repay short-term debt obligations.
P-2	Issuers (or supporting institutions) rated Prime-2 have a strong ability to repay short-term debt obligations.
P-3	Issuers (or supporting institutions) rated Prime-3 have an acceptable ability to repay short-term obligations.
NP	Issuers (or supporting institutions) rated Not Prime do not fall within any of the Prime rating categories.

Fitch Investors Service, Inc. Short-Term Ratings
Category	Definition
F1	Highest short-term credit quality. Indicates the strongest intrinsic capacity for timely payment of financial commitments; may have an added “+” to denote any exceptionally strong credit feature.
F2	Good short-term credit quality. Good intrinsic capacity for timely payment of financial commitments.
F3	Fair short-term credit quality. The intrinsic capacity for timely payment of financial commitments is adequate.
B	Speculative short-term credit quality. Minimal capacity for timely payment of financial commitments, plus heightened vulnerability to near term adverse changes in financial and economic conditions.
C	High short-term default risk. Default is a real possibility.
RD	Restricted default. Indicates an entity that has defaulted on one or more of its financial commitments, although it continues to meet other financial obligations. Typically applicable to entity ratings only.
D	Default Indicates a broad-based default event for an entity, or the default of a short-term obligation.

D-3

Standard & Poor’s Municipal Short-Term Note Ratings
Category	Definition
SP-1	Strong capacity to pay principal and interest. An issue determined to possess a very strong capacity to pay debt service is given a plus (+) designation.
SP-2	Satisfactory capacity to pay principal and interest, with some vulnerability to adverse financial and economic changes over the term of the notes.
SP-3	Speculative capacity to pay principal and interest.

Moody’s US Municipal Short-Term Debt Ratings
Category	Definition
MIG 1	This designation denotes superior credit quality. Excellent protection is afforded by established cash flows, highly reliable liquidity support, or demonstrated broad-based access to the market for refinancing.
MIG 2	This designation denotes strong credit quality. Margins of protection are ample, although not as large as in the preceding group.
MIG 3	This designation denotes acceptable credit quality. Liquidity and cash-flow protection may be narrow, and market access for refinancing is likely to be less well-established.
SG	This designation denotes speculative-grade credit quality. Debt instruments in this category may lack sufficient margins of protection.

Moody’s Demand Obligation Ratings
Category	Definition
VMIG 1	This designation denotes superior credit quality. Excellent protection is afforded by the superior short-term credit strength of the liquidity provider and structural and legal protections that ensure the timely payment of purchase price upon demand.
VMIG 2	This designation denotes strong credit quality. Good protection is afforded by the strong short-term credit strength of the liquidity provider and structural and legal protections that ensure the timely payment of purchase price upon demand.
VMIG 3	This designation denotes acceptable credit quality. Adequate protection is afforded by the satisfactory short-term credit strength of the liquidity provider and structural and legal protections that ensure the timely payment of purchase price upon demand.
SG	This designation denotes speculative-grade credit quality. Demand features rated in this category may be supported by a liquidity provider that does not have an investment grade short-term rating or may lack the structural and/or legal protections necessary to ensure the timely payment of purchase price upon demand.
