PRIME MONEY MARKET
1. WHAT IS THE FUND'S INVESTMENT OBJECTIVE?
Prime Money Market seeks to earn the highest level of current income
while preserving the value of your investment.
2. WHAT IS THE FUND'S INVESTMENT STRATEGY?
The fund earns its income by investing in high-quality, cash-equivalent
securities. These securities are short-term obligations of banks,
governments and corporations that are payable in U.S. dollars.
Additional information about Prime Money Market's investments is
available in its annual and semiannual reports. In these reports you will
find a discussion of the market conditions and investment strategies that
significantly affected the fund's performance during the most recent fiscal
period. You may get these reports at no cost by calling us.
3. WHAT ARE THE SIGNIFICANT RISKS OF 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. Although the fund seeks to preserve the
value of your investment at $1.00 per share, it is possible to lose
money by investing in the fund.
* Because cash-equivalent securities are among the safest securities
available, the interest they pay is among the lowest for income-paying
securities. Accordingly, the yield on this fund will likely be lower
than funds that invest in longer-term or lower-quality securities.

Information contained in our Investor Services Guide pertains to
shareholders who invest directly with American Century rather than through
an employer-sponsored retirement plan or through a financial intermediary.
If you own or are considering purchasing fund shares through an
employer-sponsored retirement plan or financial intermediary, your ability
to purchase shares of the fund, exchange them for shares of other American
Century funds, and redeem them will depend on the terms of your plan or
financial intermediary. If you have questions about investing in an
employer-sponsored retirement plan or through a financial intermediary,
call an Institutional Service Representative at 1-800-345-3533.
