Money Market funds are not insured or guaranteed by FDIC or any other government agency and 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. If there is a material difference between the quoted total return and the quoted current yield, the yield quotation more closely reflects the current earnings of the Money Market Fund than the total return quotation. Yields computed by SEC-prescribed calculations and are subject to change.
