The U.S. Treasury Temporary Guarantee Program provides a guarantee to participating money market mutual fund shareholders based on the number of shares invested in the Fund at the close of business on September 19, 2008. Any increase in the number of shares a shareholder holds after the close of business on September 19, 2008 will not be guaranteed. If a shareholder closes his/her account with the Fund or broker-dealer, any future investment in the Fund will not be guaranteed. If the number of shares a shareholder holds fluctuates over the period, the shareholder will be covered for either the number of shares held as of the close of business on September 19, 2008, or the current amount, whichever is less. The Program expires on December 18, 2008, unless extended by the United States Treasury.
