                      Supplement dated November 3, 2000 to
           the Statement of Additional Information dated June 1, 2000
                       as supplemented September 29, 2000


This supplement supersedes and replaces in its entirety the Supplement dated
September 29, 2000.

The following replaces in its entirety the second paragraph appearing under the
heading "INVESTMENT STRATEGIES AND RISKS -- MUNICIPAL BOND" on page 16 of the
Statement of Additional Information:

         "For purposes of the Fund's investment policies and limitations, the
     term "municipal bonds" includes debt obligations of varying maturities
     issued to obtain Funds for various public purposes, including the
     construction of a wide range of public facilities, the refunding of
     outstanding obligations, the obtaining of Funds for general operating
     expenses and the lending of such Funds to other public institutions and
     facilities. In addition, certain types of industrial development bonds are
     issued by or on behalf of public authorities to obtain funds to provide
     for the construction, equipment, repair or improvement of privately
     operated facilities ("private activity bonds"). Such obligations are
     considered to be municipal bonds appropriate for investment by the Fund,
     provided that the interest paid thereon, in the opinion of bond counsel,
     is exempt from federal income taxes.

         The Fund may also invest in municipal lease obligations, which may
     take the form of a lease, an installment purchase or a conditional sales
     contract. Municipal lease obligations are issued by state and local
     governments and authorities to acquire land, equipment and facilities such
     as state and municipal vehicles, telecommunications and computer
     equipment, and other capital assets. Interest payments on qualifying
     municipal leases are exempt from federal income taxes. The Fund may
     purchase these obligations directly, or they may purchase participation
     interests in such obligations. Municipal leases are generally subject to
     greater risks than general obligation or revenue bonds. State laws set
     forth requirements that states or municipalities must meet in order to
     issue municipal obligations, and such obligations may contain a covenant
     by the issuer to budget for, appropriate, and make payments due under the
     obligation. However, certain municipal lease obligations may contain
     "non-appropriation" clauses which provide that the issuer is not obligated
     to make payments on the obligation in future years unless funds have been
     appropriated for this purpose each year. Accordingly, such obligations are
     subject to "non-appropriation" risk. While municipal leases are secured by
     the underlying capital asset, it may be difficult to dispose of such
     assets in the event of non-appropriation or other default. All direct
     investments by the Fund in municipal lease obligations shall be deemed
     illiquid and shall be valued according to the Fund's Procedures for
     Valuing Securities current at the time of such valuation.

              As used in this Statement of Additional Information, interest
     which is "tax-exempt" or "exempt from federal income taxes" means interest
     on municipal securities which is excluded


                                       1

     from gross income for federal income tax purposes, but which may give rise
     to federal alternative minimum tax liability. The principal and interest
     payments on private activity bonds (such as industrial development or
     pollution control bonds) are the responsibility of the industrial user
     and, therefore, are not backed by the taxing power of the issuing
     municipality. Such obligations are included within the term municipal
     bonds if the interest paid thereon qualifies for exemption from federal
     income tax, but the interest on private activity bonds will be considered
     to be an item of preference for purposes of alternative minimum tax
     liability under the Internal Revenue Code of 1986, as amended (the
     "Code"). See "Dividends, Distributions and Tax Matters" below."


Effective October 10, 2000, The Bank of New York, 90 Washington Street, 11th
Floor, New York, New York 10286, will act as custodian of all securities and
cash of AIM Money Market Fund.

The following information replaces in its entirety the second paragraph
appearing under the heading "SALES CHARGES AND DEALER CONCESSIONS - ALL GROUPS
OF AIM FUNDS" on page 58 of the Statement of Additional Information:

                  "In addition to, or instead of, amounts paid to dealers as a
     sales commission, AIM Distributors may, from time to time, at its expense
     or as an expense for which it may be compensated under a distribution
     plan, if applicable, pay a bonus or other consideration or incentive to
     dealers. At the option of the dealer, such incentives may take the form of
     payment for travel expenses, including lodging, incurred in connection
     with trips taken by qualifying registered representatives and their
     families to places within or outside the United States. The total amount
     of such additional bonus payments or other consideration shall not exceed
     0.25% of the public offering price of the shares sold or of average daily
     net assets of the AIM Fund attributable to that particular dealer. Any
     such bonus or incentive programs will not change the price paid by
     investors for the purchase of the applicable AIM Fund's shares or the
     amount that any particular AIM Fund will receive as proceeds from such
     sales. Dealers may not use sales of the AIM Funds' shares to qualify for
     any incentives to the extent that such incentives may be prohibited by the
     laws of any state."

The following are added as new categories of purchasers who will not pay
initial sales charges on purchases of Class A shares, under the heading
"REDUCTIONS IN INITIAL SALES CHARGES - PURCHASES AT NET ASSET VALUE" on page 61
of the Statement of Additional Information:

     "o       Qualified State Tuition Programs created and maintained in
              accordance  with Section 529 of the U.S. Internal Revenue Code
              of 1986, as amended; and

      o       Participants in select brokerage programs for defined
              contribution plans and rollover IRAs who purchase shares
              through an electronic brokerage platform offered by entities
              with which AIM Distributors has entered into a written
              agreement."
