The following language is added as the last paragraph under the Buying and Selling Shares Through a Financial Intermediary section of the prospectuses. All three classes may not be available for all funds.

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.

The following sub-section is added in the Additional Policies Affecting Your Investment section after the sub-section Redemption of Shares in Accounts Below Minimum in the prospectuses.

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.
