PRIME MONEY MARKET FUND
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
yields on funds that invest in longer-term or lower-quality securities.

restrictions may apply. For your protection, some redemption requests
require a signature guarantee.
8. HOW ARE FUND DISTRIBUTIONS MADE AND TAXED?

a money market fund, its distributions generally will be taxed as ordinary
income. If the fund's share price were to go up or down, its annual

option.
