Pursuant to Rule 497(e) of the Securities Act of 1933, we are submitting, in connection with amendments that were filed with respect to the statutory prospectuses for U.S. Global Investors Funds Investor Class Shares and Institutional Class Shares, an exhibit containing interactive data format risk/return summary information using the eXtensible Business Reporting Language (XBRL).

The amendment to the Institutional Class Shares’ prospectus reflects a change in the minimum initial investment from $5 million to $1 million as well as reductions to the redemption fees and related holding periods for each fund.

Sincerely,
