            AIM INTERNATIONAL EMERGING GROWTH FUND - CLASS A, B AND C


                       Supplement dated December 22, 2004
                   to the Prospectus dated April 30, 2004, as
                   supplemented April 30, 2004, May 18, 2004,

Effective December 30, 2004, AIM International Emerging Growth Fund will change
its name to "AIM International Small Company Fund".

Accordingly, the following information replaces in its entirety the second and
third paragraphs under the section entitled "INVESTMENTS OBJECTIVE AND
STRATEGIES" on page 1 of the prospectus:

                  "The fund seeks to meet its objective by investing, normally,
         at least 80% of its assets in securities of small international
         companies. In complying with this 80% investment requirement, the fund
         will invest primarily in marketable equity securities, including
         convertible securities, but its investments may include other
         securities, such as synthetic instruments. Synthetic instruments are
         investments that have economic characteristics similar to the fund's
         direct investments, and may include warrants, futures, options,
         exchange-traded funds and American Depository Receipts. The fund
         considers a company to be a small-capitalization company if it has a
         market capitalization, at the time of purchase, no larger than the
         largest capitalized company included in the Russell 2000(R) Index
         during the most recent 11-month period (based on month-end data) plus
         the most recent data during the current month. The Russell 2000(R)
         Index measures the performance of the 2,000 smallest companies in the
         Russell 3000(R) Index, which measures the performance of the 3,000
         largest U.S. companies. The Russell 2000(R) Index is widely regarded as
         representative of small cap stocks. These securities may include common
         stocks, convertible bonds, convertible preferred stocks and warrants.
         Under normal conditions, the top 10 holdings may comprise up to
         one-third of the fund's total assets.

                  At least 80% of the fund's total assets will be invested in
         securities of companies located in countries outside the United States.
         The fund will normally invest in companies located in at least four
         countries outside of the United States. The fund may invest in up to
         35% of its total assets in the securities of foreign companies located
         in developing countries, i.e., those that are in the initial stages of
         their industrial cycles. The fund may invest up to 20% of its total
         assets in securities of U.S. companies."

The following information is added after the section entitled "OTHER INFORMATION
- - CAPITAL GAINS DISTRIBUTIONS" on page 5 of the prospectus:

         "FUTURE LIMITED FUND OFFERING

         Due to the sometimes limited availability of common stocks of smaller
         companies that meet the investment criteria for the fund, the fund may
         limit public sale of its shares to certain new investors after assets
         reach approximately $500 million.

         The fund may resume sales of shares to new investors at some future
         date if the Board of Trustees determines that doing so would be in the
         best interest of the shareholders."

         80% of net assets for AIM European Small Company Fund and up to 80% of
         total assets for AIM Global Value Fund) in foreign securities."

         For purposes of the foregoing sentence, "assets" means net assets, plus
         the amount of any borrowings for investment purposes. The Fund will
         provide written notice to its shareholders prior to any change to this
         policy, as required by the 1940 Act Laws, Interpretations and
