The second paragraph under the heading entitled "PERFORMANCE INFORMATION" on
Page 2 of the Prospectus is deleted in its entirety.
The following information replaces in its entirety the first bullet appearing

o "James O. Baker, C.F.A., Senior Portfolio Manager, who has been
responsible for the fund since 1999 and has been associated with the
subadvisor and/or its affiliates since 1992."
The fourth paragraph under the heading entitled "FINANCIAL HIGHLIGHTS" on Page

The following new section is added immediately after the section entitled
"SHAREHOLDER INFORMATION-REDEEMING SHARES-REDEMPTION OF AIM CASH RESERVE SHARES
OF AIM MONEY MARKET FUND ACQUIRED BY EXCHANGE" on Page A-4 of the Prospectus:
"REDEMPTION OF CLASS B SHARES OR CLASS C SHARES ACQUIRED BY EXCHANGE FROM
AIM CASH RESERVE SHARES OF AIM MONEY MARKET FUND
We will begin the holding period for purposes of calculating the
CDSC on Class B shares or Class C shares acquired by exchange from AIM
Cash Reserve Shares of AIM Money Market Fund at the time of the exchange
into Class B shares or Class C shares."
The first paragraph under the heading "SHAREHOLDER INFORMATION-EXCHANGING
SHARES-PERMITTED EXCHANGES" on Page A-6 of the Prospectus is replaced with the
following:
"Except as otherwise stated below, you may exchange your shares for
shares of the same class of another AIM Fund. You may exchange AIM Cash
Reserve Shares of AIM Money Market Fund for Class A shares of another AIM
Fund, or vice versa. You may also exchange AIM Cash Reserve Shares of AIM
Money Market Fund for Class B shares or Class C shares of another AIM
Fund, but only if the AIM Cash Reserve Shares were purchased directly and
not acquired by exchange. You may be required to pay an initial sales
charge when exchanging from a Fund with a lower initial sales charge than
the one into which you are exchanging. If you exchange from Class A shares
not subject to a CDSC into Class A shares subject to those charges, you
will be charged a CDSC when you redeem the exchanged shares. The CDSC
charged on redemption of those shares will be calculated starting on the
date you acquired those shares through exchange."
A new paragraph (5) is added under the heading "SHAREHOLDER INFORMATION-
EXCHANGING SHARES-PERMITTED EXCHANGES-YOU WILL NOT PAY A SALES CHARGE WHEN
EXCHANGING: " on Page A-6 of the Prospectus, and the new paragraph (5) reads
as follows:
"(5) AIM Cash Reserve Shares of AIM Money Market Fund for Class B
shares and Class C shares. "
