Example

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


	1 year	3 years	5 years	10 years
Investor Class	$114	$357	$618	$1,363
I Class	$94	$294	$510	$1,131
Y Class	$79	$246	$428	$955
A Class	$707	$985	$1,283	$2,126
C Class	$216	$665	$1,140	$2,258
R Class	$165	$512	$882	$1,920


	1 year	3 years	5 years	10 years
R5 Class	$94	$294	$510	$1,131
R6 Class	$79	$246	$428	$955
G Class	$1	$3	$6	$13

Portfolio Turnover

The fund pays transaction costs, such as commissions, when it buys and sells securities (or “turns over” its portfolio). A higher portfolio turnover rate may indicate higher transaction costs and may result in higher taxes when fund shares are held in a taxable account. These costs, which are not reflected in annual fund operating expenses or in the example, affect the fund’s performance. During the most recent fiscal year, the fund’s portfolio turnover rate was 132% of the average value of its portfolio.

Principal Investment Strategies

Under normal market conditions, the fund invests at least 80% of its net assets in equity securities issued by real estate investment trusts (REITs) and other companies engaged in the real estate industry (collectively, real estate securities). A REIT invests primarily in income-producing real estate or makes loans to persons involved in the real estate industry. The portfolio managers consider a company to be engaged in the real estate industry if at least 50% of its revenues or 50% of the market value of its assets at the time the securities are purchased by the fund are attributed to the ownership, construction, management or sale of real estate. The portfolio managers look for real estate securities they believe will provide superior returns, focusing on companies with the potential for stock price appreciation, plus sustainable growth of cash flow to investors. The portfolio managers use the following investment techniques to construct the portfolio: 1) top down fundamental analysis of property sectors and geographic regions that allows the managers to allocate assets among securities with exposure to different segments and geographies of the real estate market, 2) bottom up fundamental stock research, and 3) benchmark sensitive portfolio construction that reflects the property sectors and regions, and the individual weights thereof, of the S&P Developed REIT Index, a member of the S&P Global Property Index Series. Of these techniques, the portfolio managers place particular emphasis on property sector research. These techniques also help the portfolio managers sell the stocks of companies whose fundamentals are no longer attractively priced. Because the fund’s investment strategy is concentrated in real estate securities, the fund may hold a relatively small number of security positions compared to other funds that hold securities in a broader range of industries.

The fund invests primarily in equity securities of companies located in developed countries world-wide (including the United States), but may also invest in emerging markets. Under normal market conditions, the fund will invest at least 30% (unless the portfolio managers deem market conditions unfavorable, in which case the fund would invest at least 20%) of its assets in securities of issuers located outside the United States. The fund will allocate its assets among at least three different countries (one of which may be the United States).

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

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

•REITs Risk — Investments in REITs are subject to credit risk and interest rate risk with respect to the loans made by the REITs in which the fund invests. Credit risk is the risk that the borrower will not be able to make interest and principal payments on the loan to the REIT when they are due. Interest rate risk is the risk that a change in the prevailing interest rate will cause the value of the loan portfolio held by the REIT to rise or fall. Additionally, the fund’s shareholders will indirectly bear a proportionate share of the operating expenses of a REIT in which the fund invests.

•Concentration Risk — Because the fund concentrates its investments in real estate securities, it may be subject to greater risks and market fluctuations than a portfolio investing in a broader range of industries.

•Foreign Securities Risk — The fund invests in foreign securities, which can be riskier than investing in U.S. securities. Securities of foreign issuers may be less liquid, more volatile and harder to value than U.S. securities.

•Emerging Markets Risk — Investing in securities of companies located in emerging market countries generally is riskier than investing in securities of companies located in foreign developed countries.

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

•Market Risk — The value of the fund’s shares will go up and down based on the performance of the companies whose securities it owns and other factors generally affecting the securities market. Market risks, including political, regulatory, economic and social developments, can affect the value of the fund’s investments. Natural disasters, public health emergencies, war, terrorism and other unforeseeable events may lead to increased market volatility and may have adverse long-term effects on world economies and markets generally.

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

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

•Principal Loss Risk — At any given time your shares may be worth less than the price you paid for them. In other words, it is possible to lose money by investing in the fund.

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

Fund Performance

The following bar chart and table provide some indication of the risks of investing in the fund. The bar chart shows changes in the fund’s performance from year to year for Investor Class shares.

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

There is no minimum initial investment amount for Y, R5 or R6 Class shares.

Employer-sponsored retirement plans are not eligible to invest in the I or Y Class.

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

G Class shares are available for purchase by other funds offered by American Century Investments for which it charges a management fee. In its sole discretion, American Century Investments may also make G Class shares available for purchase by other institutional clients for which American Century Investments provides investment management services for a fee pursuant to an investment advisory agreement.

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 Y, R6 and G Classes. 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 high total investment return through a combination of capital appreciation and current income.

What are the fund’s principal investment strategies?

Under normal market conditions, the fund invests at least 80% of its net assets in equity securities issued by real estate investment trusts (REITs) and other companies engaged in the real estate industry. The fund may change this 80% policy only upon 60 days’ prior written notice to shareholders. A REIT invests primarily in income-producing real estate or makes loans to persons involved in the real estate industry. The portfolio managers consider a company to be engaged in the real estate industry if at least 50% of its revenues or 50% of the market value of its assets at the time its securities are purchased by the fund are attributed to the ownership, construction, management or sale of real estate. The portfolio managers look for real estate securities they believe will provide superior returns. The portfolio managers attempt to focus the fund’s investments on real estate companies and REITs with the potential for stock price appreciation, plus sustainable growth of cash flow to investors.


			Equity securities include common stock, preferred stock, and equity-equivalent securities, such as convertible securities, stock futures contracts or stock index futures contracts.

Some REITs, called equity REITs, buy real estate, and investors receive income from the rents received and from any profits on the sale of its properties. Other REITs, called mortgage REITs, lend money to building developers and other real estate companies, and receive income from interest paid on those loans. There are also hybrid REITs, which engage in both owning real estate and making loans. If a REIT meets certain requirements, it is not taxed on the income it distributes to its investors.

The portfolio managers use the following investment techniques to construct the portfolio: 1) top down fundamental analysis of property sectors and geographic regions that allows the portfolio managers to allocate assets among securities with exposure to different segments and geographies of the real estate market, 2) bottom up fundamental stock research, and 3) benchmark sensitive portfolio construction that reflects the property sectors and regions, and the individual weights thereof, of the S&P Developed REIT Index, a member of the S&P Global Property Index Series. Of these investment techniques, the portfolio managers place particular emphasis on property sector research. Company level research is focused on earnings, net asset value per share and a quantitative assessment of management strategy. These techniques also help the portfolio managers sell the stocks of companies whose fundamentals are no longer attractively priced. Because the fund’s investment strategy is concentrated in real estate securities, it may hold a relatively small number of security positions compared to other funds that hold securities in a broader range of industries.

The portfolio managers evaluate each company’s ability to generate earnings over an earnings cycle, not just for the next one or two years. The portfolio managers focus research efforts on determining the normalized earnings and earnings growth of a company, from which they determine if the company’s current price fully reflects its long-term value.

The fund’s assets will be invested primarily in equity securities of issuers located in developed countries world-wide (including the United States). When the portfolio managers believe it is prudent, a portion of the fund’s assets may be invested in equity securities of issuers located in emerging markets. The portfolio managers consider countries other than those on the developed countries list to be emerging market countries. Under normal market conditions, the fund will invest at least 30% (unless the portfolio managers deem market conditions unfavorable, in which case the fund would invest at least 20%) 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 United States).


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

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

In addition to investing the fund’s assets based on the factors described above, the portfolio managers believe that it is important to allocate the fund’s holdings across different countries and geographical regions in an effort to manage the risks of a global 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.

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

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?

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

Because the fund concentrates its investments in real estate securities, it may be subject to greater risks and market fluctuations than a fund representing a broader range of industries. In addition, market performance tends to be cyclical and, in the various cycles, certain investment styles may fall in and out of favor. If the market is not favoring the fund’s style, the fund’s gains may not be as big as, or its losses may be bigger than, other equity funds using different investment styles.

To the extent the fund invests in mortgage REITs, it will be subject to credit risk and interest rate risk with respect to the loans made by the REITs in which the fund invests. Credit risk is the risk that the borrower will not be able to make interest and principal payments on the loan to the REIT when they are due. Interest rate risk is the risk that a change in the prevailing interest rate will cause the value of the loan portfolio held by the REIT to rise or fall. Generally, when interest rates rise, the value of the loan portfolio will decline. The opposite is true when interest rates decline. The degree to which interest rate changes affect the fund’s performance varies and is related to the specific characteristics of the loan portfolios of the mortgage REITs in which the fund invests. Additionally, the fund’s shareholders will indirectly bear a proportionate share of the operating expenses of a REIT in which the fund invests.

The fund invests in foreign securities, which is generally riskier than investing in U.S. securities. These additional risks include fluctuations in currency exchange rates, less stable political and economic structures, reduced availability of public information, and lack of uniform financial reporting and regulatory practices similar to those that apply in the United States. Securities of foreign issuers may be less liquid, more volatile and harder to value than U.S. securities.

In addition, investments in foreign countries are subject to currency risk, meaning that because a portion of the fund’s investments are 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. Those countries also may lack the legal, business and social framework to support securities markets.

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. Market risks, including political, regulatory, economic and social developments, can affect the value of the fund’s investments. Natural disasters, public health emergencies, war, terrorism and other unforeseeable events may lead to increased market volatility and may have adverse long-term effects on world economies and markets generally.

The value of the fund’s shares may fluctuate significantly in the short term.

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.

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 manage-ment 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 indepe-ndent 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 Company Act).

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

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


Management Fees Paid by the Fund to the Advisor as a Percentage of Average Net Assets for the Fiscal Year Ended October 31, 2023	Investor Class	I Class	Y Class	A Class	C Class	R Class	R5 Class	R6 Class	G Class

Investing Through a Financial Intermediary

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


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

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.

I Class

I Class shares are available for purchase without sales charges or commissions by endowments, foundations, large institutional investors and financial intermediaries. Employer-sponsored retirement plans may not invest in I Class shares, except that plans invested in the I Class prior to April 10, 2017 may make additional purchases.

Y Class

A Class

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

C Class

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

R Class

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

R5 and R6 Class

R5 and R6 Class shares are available for purchase without sales charges or commissions by participants in certain employer-sponsored retirement plans. R5 and R6 Class shares may be purchased or redeemed only through employer-sponsored retirement plans where a financial intermediary provides retirement recordkeeping services to plan participants.

Calculation of Sales Charges

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

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

A Class

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


Purchase Amount	Sales Charge as a % 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 mutual fund (excluding certain assets in money market accounts, but including account assets invested in Qualified Tuition Programs under Section 529) to reduce your A Class sales charge in the following ways:

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

•Certain trust accounts

•Solely controlled business accounts

•Single-participant retirement plans

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

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

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

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

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

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

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

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

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

•Current officers, directors or employees of American Century Investments

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

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

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

C Class

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

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

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

Calculation of Contingent Deferred Sales Charge (CDSC)

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

CDSC Waivers

Any applicable CDSC for the 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 C Class shares

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

•tax-free returns of excess contributions to IRAs

•redemptions due to death or post-purchase disability

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

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

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

Reinstatement Privilege

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

Employer-Sponsored Retirement Plans

Certain group employer-sponsored retirement plans that hold a single account for all plan participants with the fund, or that are part of a retirement plan or platform offered by banks, broker-dealers, financial advisors or insurance companies, or serviced by retirement recordkeepers are eligible to purchase Investor, A, C, R, R5 and R6 Class shares. Employer-sponsored retirement plans are not eligible to purchase I or Y Class shares. However, employer-sponsored retirement plans that were invested in the I Class prior to April 10, 2017 may make additional purchases. 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 mutual fund without a sales charge if you meet the following criteria:

•The exchange is for a minimum of $100

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

For purposes of computing any applicable CDSC on shares that have been exchanged, the holding period will begin as of the date of purchase of the original fund owned. Exchanges from a money market fund are subject to a sales charge on the fund being purchased,

unless the money market fund shares were acquired by exchange from a fund with a sales charge or by reinvestment of dividends or capital gains distributions.

Moving Between Share Classes and Accounts

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

Buying and Selling Shares Through a Financial Intermediary

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

•minimum investment requirements

•exchange policies

•fund choices

•cutoff time for investments

•trading restrictions

In addition, your financial intermediary may charge a transaction fee for the purchase or sale of fund shares. Those charges are retained by the financial intermediary and are not shared with American Century Investments or the 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.

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

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

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

Unless otherwise specified below, the minimum initial investment amount to open an account is $2,500. However, American Century Investments will waive the fund minimum if you make an initial investment of at least $500 and continue to make automatic investments of at least $100 a month until reaching the fund minimum. Investors opening accounts through financial intermediaries may open an account with $250, but the financial intermediaries may require their clients to meet different investment minimums.

Coverdell Education Savings Account (CESA) and IRAs			$1,0001,2
Employer-sponsored retirement plans			No minimum

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

Subsequent Purchases

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

Eligibility for I Class Shares

The I Class shares are made available for purchase by individuals and large institutional shareholders such as bank trust departments, corporations, endowments, foundations and financial advisors that meet the fund’s minimum investment requirements. Employer-sponsored retirement plans may not invest in I Class shares, except that plans invested in the I Class prior to April 10, 2017 may make additional purchases.

Minimum Initial Investment Amounts for I Class

The minimum initial investment amount is generally $5 million ($3 million for endowments and foundations) per fund. If you invest with us through a financial intermediary, this requirement may be met if your financial intermediary aggregates your investments with those of other clients into a single group, or omnibus, account that meets the minimum. The minimum investment requirement may be waived if you have an aggregate investment in the American Century family of funds of $10 million or more ($5 million for endowments and foundations). This includes accounts held directly with American Century and those held through a financial intermediary. American Century Investments also may waive the minimum initial investment in other situations it deems appropriate.

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

Eligibility for Y Class Shares

Y Class shares are available for purchase without sales charges or commissions through financial intermediaries that offer fee based advisory programs. Y Class shares may be purchased only through financial intermediaries that trade in omnibus accounts with American Century Investments. Y Class shares may not be purchased by shareholders investing through employer-sponsored retirement plans or individuals investing directly with American Century Investments.

Minimum Initial Investment Amounts for Y Class

There is no minimum initial investment amount or subsequent investment amount for Y Class shares, but financial intermediaries may require different investment minimums.

The fund’s R5 and 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.

R5 and R6 Class shares are not available to retail accounts, traditional or Roth IRAs, SEP IRAs, SIMPLE IRAs, SARSEPs or Coverdell education savings accounts.

Minimum Initial Investment Amounts for R5 and R6 Classes

There is no minimum initial investment amount or subsequent investment amount for R5 or R6 Class shares, but financial intermediaries or plan recordkeepers may require plans to meet different investment minimums.

Eligibility and Minimum Initial Investment Amounts for G Class

Redemptions

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

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

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

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

Special Requirements for Large Redemptions

If, during any 90-day period, you redeem fund shares worth more than $250,000 (or 1% of the value of a fund’s assets if that amount is less than $250,000), we reserve the right to pay part or all of the redemption proceeds in excess of this amount in readily marketable securities instead of in cash. To the extent practicable, these securities will represent your pro rata share of the fund’s securities.

We will value these securities in the same manner as we do in computing the fund’s net asset value. We may provide these securities in lieu of cash without prior notice. Also, if payment is made in securities, you may have to pay brokerage or other transaction costs to convert the securities to cash. These securities remain subject to market risk until sold, and you may incur capital gains and/or losses when you sell the securities.

If your redemption would exceed this limit and you would like to avoid being paid in securities, please provide us with an unconditional instruction to redeem at least 15 days prior to the date on which the redemption transaction is to occur. The instruction must specify the dollar amount or number of shares to be redeemed and the date of the transaction. This minimizes the effect of the redemption on a fund and its remaining investors.

Redemption of Shares in Accounts Below Minimum

If your account balance falls below the minimum initial investment amount for any reason, or if you cancel your automatic monthly investment plan prior to reaching the fund minimum, American Century Investments reserves the right to redeem the shares in the account and send the proceeds to your address of record. Prior to doing so, we will notify you and give you 60 days to meet the minimum or reinstate your automatic monthly investment plan. Please note that shares redeemed in this manner may be subject to a sales charge if held less than the applicable time period. You may incur tax liability as a result of the redemption. For I Class shares, we reserve the right to convert your shares to Investor Class shares of the same fund. The Investor Class shares have a unified management fee that is 0.20 percentage points higher than the I Class.

Small Distributions and Uncashed Distribution Checks

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

Signature Guarantees

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

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

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

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

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

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

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

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

Canceling a Transaction

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

Frequent Trading Practices

Frequent trading and other abusive trading practices may disrupt portfolio management strategies and harm fund performance. If the cumulative amount of frequent trading activity is significant relative to a fund’s net assets, the fund may incur trading costs that are higher than necessary as securities are first purchased then quickly sold to meet the redemption request. In such case, the fund’s performance could be negatively impacted by the increased trading costs created by frequent trading if the additional trading costs are significant.

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

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

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

•within seven days of the purchase, or

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

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

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

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

•redemption of shares to pay fund or account fees;

•CheckWriting redemptions;

•redemptions requested following the death of a registered shareholder;

•transactions through automatic purchase or redemption plans;

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

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

•transactions by 529 college savings plans and funds of funds (however shareholders of American Century’s funds of funds are subject to the limitations); and

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

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

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

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

Your Responsibility for Unauthorized Transactions

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

A Note About Mailings to Shareholders

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

Right to Change Policies

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

Share Price and Distributions

Share Price

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


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

The value of the securities and other assets and liabilities held by the fund are determined by the advisor, as the valuation designee, pursuant to its valuation policies and procedures. The fund’s Board of Trustees oversees the valuation designee and at least annually reviews its valuation policies and procedures. Valuations are determined in accordance with applicable federal securities laws and accounting principles generally accepted in the United States.

Portfolio securities for which market quotations are readily available are valued at their market price. Equity securities and other equity instruments for which market quotations are readily available are valued at the last reported official closing price or sale price as of the time the NAV is determined. Portfolio securities primarily traded on foreign securities exchanges that are generally open later than the NYSE are valued at the last sale price reported at the time the NAV is determined.

If the valuation designee determines that the market price for a portfolio security is not readily available or is believed by the valuation designee to be unreliable, such security is valued at fair value as determined in good faith by the valuation designee, in accordance with its policies and procedures. Circumstances that may cause the fund to determine that market quotations are not available or reliable include, but are not limited to:

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

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

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

If such circumstances occur, the valuation designee will fair value the security if the fair valuation would materially impact the fund’s NAV. While fair value determinations involve judgments that are inherently subjective, these determinations are made in good faith in accordance with the valuation designee’s valuation policies and procedures.

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

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

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

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

The value of any security or other asset denominated in a currency other than U.S. dollars is converted to U.S. dollars at the prevailing foreign exchange rate at the time the fund’s NAV is determined. Trading of securities in foreign markets may not take place every day the NYSE is open. Also, trading in some foreign markets and on some electronic trading networks may take place on weekends or holidays when the fund’s NAV is not calculated. So, the value of the fund’s portfolio may be affected on days when you will not be able to purchase, exchange or redeem fund shares.

Distributions

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


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

The fund generally expects to pay distributions from net income and capital gains, if any, once a year in December. It may make more frequent distributions if necessary to comply with Internal Revenue Code provisions.

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

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

Taxes

Some of the tax consequences of owning shares of the 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 and the stock was not on loan at the time of the dividend.

The fund does not expect a significant portion of its distributions to be derived from qualified dividend income. 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 mutual funds — are subject to capital gains tax. Short-term capital gains are gains on fund shares you held for 12 months or less. Long-term capital gains are gains on fund shares you held for more than 12 months. If your shares decrease in value, their sale or exchange will result in a long-term or short-term capital loss. However, you should note that loss realized upon the sale or exchange of shares held for six months or less will be treated as a long-term capital loss to the extent of any distribution of long-term capital gain to you with respect to those shares. If a loss is realized on the redemption of fund shares, the reinvestment in additional fund shares within 30 days before or after the redemption may be subject to the wash sale rules of the Internal Revenue Code. This may result in a postponement of the recognition of such loss for federal income tax purposes.

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

Buying a Dividend

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

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

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

Note on Tax Reporting

If you invest in other American Century Investments funds, you may receive tax reporting documents (such as Forms 1099-B, 1099-DIV, 1099-INT and 1099-R, if applicable) for such other funds prior to receiving the 1099-DIV or 1099-B for the fund. The separate mailing of these forms for the fund allows American Century Investments additional time to incorporate necessary information related to its investments in REITs. Since a portion of the dividends paid by REITs may represent a return of capital to the fund, such distributions may result in a portion of the fund’s distributions being classified as a return of capital. REITs typically do not indicate what proportion of their dividends represent a return of capital in time to allow American Century Investments to include complete and accurate tax forms at the same time that tax forms are mailed for its other funds. Although distributions classified as returns of capital (which are listed as “nontaxable distributions” on Form 1099-DIV) are not taxable to you, these distributions reduce the cost basis of your investment in the fund and affect information contained on the 1099-B.

Multiple Class Information

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

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

Service, Distribution and Administrative Fees

Investment Company Act Rule 12b-1 permits mutual funds that adopt a written plan to pay certain expenses associated with the distribution of their shares out of fund assets. 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 intermediaries; and (3) marketing and promotional services, including business planning assistance, educating personnel about the fund, and sponsorship of sales meetings, which may include covering costs of providing speakers, meals and other entertainment. The distributor may pay partnership and/or sponsorship fees to support seminars, conferences, and other programs designed to educate intermediaries about the fund and may cover the expenses associated with attendance at such meetings, including travel costs. The distributor also may pay fees related to obtaining data regarding intermediary or financial advisor activities to assist American Century Investments with sales reporting, business intelligence, and training and education opportunities. These payments and activities are intended to provide an incentive to intermediaries to sell the fund by educating them about the fund and helping defray the costs associated with offering the fund. These payments may create a conflict of interest by influencing the intermediary to recommend the fund over another investment. Ask your salesperson or visit your financial intermediary’s website for more information. The amount of any payments described by this paragraph is determined by the advisor or the distributor, and all such amounts are paid out of their available assets, and not paid by you or the fund. As a result, the total expense ratio of the fund will not be affected by any such payments.

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

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

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

•share price at the beginning of the period

•investment income and capital gains or losses

•distributions of income and capital gains paid to investors

•share price at the end of the period

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

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

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

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

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

The Financial Highlights that follow have been audited by Deloitte & Touche LLP. The Report of Independent Registered Public Accounting Firm and the financial statements and financial highlights are included in the fund’s annual report, which is available upon request.

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

The following information has been provided by Edward Jones:

Effective on or after January 1, 2024, the following information supersedes prior information with respect to transactions and positions held in fund shares through an Edward Jones system. Clients of Edward Jones (also referred to as “shareholders”) purchasing fund shares on the Edward Jones commission and fee-based platforms are eligible only for the following sales charge discounts (also referred to as “breakpoints”) and waivers, which can differ from discounts and waivers described elsewhere in the mutual fund prospectus or statement of additional information (SAI) or through another broker-dealer. In all instances, it is the shareholder’s responsibility to inform Edward Jones at the time of purchase of any relationship, holdings of American Century, or other facts qualifying the purchaser for discounts or waivers. Edward Jones can ask for documentation of such circumstance. Shareholders should contact Edward Jones if they have questions regarding their eligibility for these discounts and waivers.

Breakpoints

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

Rights of Accumulation (ROA)

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

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

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

Letter of Intent (LOI)

•Through a LOI, shareholders can receive the sales charge and breakpoint discounts for purchases shareholders intend to make over a 13-month period from the date Edward Jones receives the LOI. The LOI is determined by calculating the higher of

A-2

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

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

Sales Charge Waivers

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

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

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

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

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

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

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

•Purchases of Class 529-A shares through a rollover from either another education savings plan or a security used for qualified distributions.

•Purchases of Class 529 shares made for recontribution of refunded amounts.

Contingent Deferred Sales Charge (CDSC) Waivers

•The death or disability of the shareholder.

•Systematic withdrawals with up to 10% per year of the account value.

Sales Charge Reductions and Waivers Available through PFS Investments Inc. (PFSI)

Policies Regarding Fund Purchases Held on the PSS Platform

The following information supersedes all prior information with respect to transactions and positions held in fund shares purchased through PFSI and held on the mutual fund platform of its affiliate, Primerica Shareholder Services (PSS). Clients of PFSI (also referred to as “shareholders”) purchasing fund shares on the PSS platform are eligible only for the following share classes, sales charge discounts (also referred to as “breakpoints”) and waivers, which can differ from share classes, discounts and waivers described elsewhere in this prospectus or the related statement of additional information (SAI) or through another broker-dealer. In all instances, it is the shareholder’s responsibility to inform PFSI at the time of a purchase of all holdings of American Century Funds on the PSS platform, or other facts qualifying the purchaser for discounts or waivers. PFSI may request reasonable documentation of such facts and condition the granting of any discount or waiver on the timely receipt of such documents. Shareholders should contact PSS if they have questions regarding their eligibility for these discounts and waivers.

Share Classes

a.Class A shares are available to non-retirement accounts, individual retirement accounts (IRA), SEP IRAs, SIMPLE IRAs, Keogh Plans, and all other account types.

b.Class C shares are available only to accounts with existing Class C share holdings

Breakpoints

a.Breakpoint pricing at dollar thresholds as described in the prospectus of the fund you are purchasing.

Rights of Accumulation (ROA)

a.The applicable sales charge on a purchase of Class A shares is determined by taking into account all share classes (except any assets held in group retirement plans) of American Century Funds held by the shareholder on the PSS Platform. The inclusion of eligible fund family assets in the ROA calculation is dependent on the shareholder notifying PFSI of such assets at the time of calculation. Shares of money market funds are included only if such shares were acquired in exchange for shares of another American Century Fund purchased with a sales charge. No shares of American Century Funds held by the shareholder away from the PSS platform will be granted ROA with shares of any American Century Fund purchased on the PSS platform.

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

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

Letter of Intent (LOI)

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

b.Only holdings of American Century Funds on the PSS platform are eligible for inclusion in the LOI calculation and the shareholder must notify PFSI of all eligible assets at the time of calculation.

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

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

Sales Charge Waivers

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

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

A-8

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

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

Example

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


	1 year	3 years	5 years	10 years
Investor Class	$117	$366	$634	$1,397
I Class	$97	$303	$526	$1,166

Principal Investment Strategies

Because the fund is nondiversified and its investment strategy is concentrated in real estate securities, the fund may hold a relatively small number of security positions compared to other funds that are diversified and hold securities in a broader range of industries.

Principal Risks

•Nondiversification Risk — The fund is classified as nondiversified. A nondiversified fund may invest a greater percentage of its assets in a smaller number of securities than a diversified fund. This gives the managers the flexibility to hold large positions in a small number of securities. If so, a price change in any one of those securities may have greater impact on the fund’s share price than would be the case in a diversified fund.

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

•Principal Loss Risk — At any given time your shares may be worth less than the price you paid for them. In other words, it is possible to lose money by investing in the fund.

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

Fund Performance

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

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 Y and R6 Classes. 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 high total investment return through a combination of capital appreciation and current income.

What are the fund’s principal investment strategies?

Under normal market conditions, the fund invests at least 80% of its net assets in equity securities issued by real estate investment trusts (REITs) and other companies engaged in the real estate industry. The fund may change this 80% policy only upon 60 days’ prior written notice to shareholders. A REIT invests primarily in income-producing real estate or makes loans to persons involved in the real estate industry. The portfolio managers consider a company to be engaged in the real estate industry if at least 50% of its revenues or 50% of the market value of its assets at the time its securities are purchased by the fund are attributed to the ownership, construction, management or sale of real estate. The portfolio managers look for real estate securities they believe will provide superior returns. The portfolio managers attempt to focus the fund’s investments on real estate companies and REITs with the potential for stock price appreciation, plus sustainable growth of cash flow to investors.


			Equity securities include common stock, preferred stock, and equity-equivalent securities, such as convertible securities, stock futures contracts or stock index futures contracts.

The portfolio managers use the following investment techniques to help construct the portfolio: 1) top down fundamental analysis of property sectors and geographic regions that allows the managers to allocate assets among securities with exposure to different segments and geographies of the real estate market, 2) bottom up fundamental stock research, and 3) benchmark sensitive portfolio construction that reflects the securities that comprise, and the individual weights within, the FTSE Nareit All Equity REITs Index. Of these investment techniques, the portfolio managers place particular emphasis on property sector research. Company level research is focused on earnings, net asset value per share and a quantitative assessment of management strategy. These techniques also help the portfolio managers sell the stocks of companies whose fundamentals are no longer attractively priced. Because the fund’s investment strategy is nondiversified and is concentrated in real estate securities, it may hold a relatively small number of security positions compared to other diversified funds that hold securities in a broader range of industries.

When the managers believe it is prudent, the fund may invest a portion of its assets in foreign securities when these securities meet the portfolio managers’ standards of selection.

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?

payments on the loan to the REIT when they are due. Interest rate risk is the risk that a change in the prevailing interest rate will cause the value of the loan portfolio held by the REIT to rise or fall. Generally, when interest rates rise, the value of the loan portfolio will decline. The opposite is true when interest rates decline. The degree to which interest rate changes affect the fund’s performance varies and is related to the specific characteristics of the loan portfolios of the mortgage REITs in which the fund invests. Additionally, the fund’s shareholders will indirectly bear a proportionate share of the operating expenses of a REIT in which the fund invests.

The fund is classified as nondiversified. Because it is nondiversified, it may hold large positions in a small number of securities. To the extent it maintains such positions, the price change in any one of those securities may have a greater impact on the fund’s share price than if it were diversified.

The value of the fund’s shares may fluctuate significantly in the short term.

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 Company Act).

The Investment Advisor

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 that fund except brokerage expenses, taxes, interest, fees and expenses of the independent directors (including legal counsel fees), extraordinary expenses, and expenses incurred in connection with the provision of shareholder services and distribution services under a plan adopted pursuant to Rule 12b-1 under the Investment Company Act. The difference in unified management fees among the classes is a result of their separate arrangements for non-Rule 12b-1 shareholder services. It is not the result of any difference in advisory or custodial fees or other expenses related to the management of the fund’s assets, which do not vary by class. For all classes other than the Y and R6 Classes, 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 rate of the fee is determined by applying a formula that 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), as well as exchange-traded funds managed by the advisor, that use very similar investment teams and strategies (strategy assets). The use of strategy assets, rather than fund assets alone, in calculating the fund’s fee rate could allow the fund to realize scheduled cost savings more quickly. However, it is possible that the fund’s strategy assets will not include assets of other accounts or that any such assets may not be sufficient to result in a lower fee rate.


Management Fees Paid by the Fund to the Advisor as a Percentage of Average Net Assets for the Fiscal Year Ended October 31, 2023	Investor Class	I Class	Y Class	A Class	C Class	R Class	R5 Class	R6 Class
Real Estate	1.15%	0.95%	0.80%	1.15%	1.15%	1.15%	0.95%	0.80%
