                                THE BRINSON FUNDS

                          SUPPLEMENT TO THE PROSPECTUS
                   FOR THE BRINSON FUND -- CLASS I SHARES
                      Prospectus Dated February 11, 1998


The following  information  supplements and supersedes any contrary  information
contained in the sections of the Trust's Prospectus.

      1.    Delete the fifth sentence in the section "Investment  Objectives and
            Policies - U.S.  Large  Capitalization  Equity  Fund" and insert the
            following two sentences:

                  The Series is a  non-diversified  portfolio  as  described  in
            "Investment  Considerations and Risks - Non-Diversified Status." The
            Series  seeks to achieve its  objective by investing in a wide range
            of equity  securities  of U.S.  companies  that are  traded on major
            stock exchanges as well as in the over-the-counter market.

      2.    Replace the paragraph entitled "Investment  Considerations and Risks
            -   Non-Diversified   Status  (Global  Bond  Fund  only)"  with  the
            following:

                  Non-Diversified  Status  (Global  Bond  Fund  and  U.S.  Large
            Capitalization  Equity  Fund)  -  Each  Series  is  classified  as a
            "non-diversified" investment company under the Act, which means that
            the  proportion  of the  Series'  assets that may be invested in the
            securities of a single issuer is not limited by the Act.  Since each
            Series may invest a larger  portion of its assets in the  securities
            of a single issuer than investment  companies that are classified as
            diversified  funds under the Act, an  investment  in the Global Bond
            Fund or in the U.S. Large Capitalization  Equity Fund may be subject
            to greater fluctuations in value than an investment in a diversified
            fund.

      3.    Replace  the sixth  sentence  in the  section  "General  Information
            - Organization" with the following sentence:

                  All of the Series,  except the Global Bond Fund and the U.S.
            Large Capitalization Equity Fund, are diversified portfolios.


                            This supplement is dated April 7, 1998.
