SUPPLEMENT TO THE PROSPECTUSES AND STATEMENT OF ADDITIONAL INFORMATION

                       CREDIT SUISSE EUROPEAN EQUITY FUND

THE FOLLOWING INFORMATION SUPERSEDES CERTAIN INFORMATION IN THE FUND'S
PROSPECTUSES AND STATEMENT OF ADDITIONAL INFORMATION.

     The fund's Board of Directors has approved an amendment to the
Sub-Investment Advisory Agreement (the "Sub-Advisory Agreement") by and among
the fund, Credit Suisse Asset Management, LLC ("CSAM"), the fund's investment
adviser, and Credit Suisse Asset Management Limited (the "Sub-Adviser").
Pursuant to this amendment, effective May 14, 2002, CSAM (and not your fund)
will pay the Sub-Adviser an annual fee of $250,000 (the "Total Fee"). The Total
Fee shall be an aggregate fee paid for services rendered with respect to your
fund and such other Credit Suisse Funds for which the Sub-Adviser has been
appointed to act as sub-investment adviser. The fund's Board of Directors may in
the future approve further amendments to reallocate the management fees between
CSAM and the Sub-Adviser.

     IMPORTANTLY, YOU SHOULD NOTE THAT THE AMENDMENT WILL NOT AFFECT THE FEES OR
EXPENSES APPLICABLE TO THE FUND BECAUSE ALL SUB-ADVISORY FEES WILL BE BORNE BY
CSAM.
