A: If you would like a set of the proxy materials, please call 1-866-825-6453
ext. 100 between the hours of 9:30 a.m. to 11:00 p.m. eastern time.

Q: HOW DOES A SHAREHOLDER VOTE THEIR PROXY?

A: There are several convenient methods for shareholders to vote, including the
Internet, by phone and by mail. Specific voting instructions can be found on the
shareholder's proxy card.



Q: WHAT ARE SHAREHOLDERS BEING ASKED TO VOTE ON AT THE MEETINGS?

A: There are several proposals for consideration at the Meetings.

     1.   All Funds: To elect Directors/Trustees of the Funds;

     2a.  For the shareholders of Credit Suisse Institutional Fixed Income Fund,
          Credit Suisse Institutional High Yield Fund, Credit Suisse
          Institutional International Fund, Credit Suisse Municipal Bond Fund,
          and Credit Suisse Select Equity Fund: to approve a new investment
          advisory agreement between each of the Funds and CSAM;

     2b.  For the shareholders of Credit Suisse Institutional Fixed Income Fund,
          Credit Suisse Institutional High Yield Fund, Credit Suisse
          Institutional International Fund, Credit Suisse Municipal Bond Fund,
          and Credit Suisse Select Equity Fund: to approve the retention or
          payment of fees paid or payable to CSAM;

     3.   For the shareholders of Credit Suisse High Income Fund, Credit Suisse
          Municipal Money Market Fund and Credit Suisse U.S. Government Money
          Fund: to approve an amended distribution plan for each class of each
          Fund;

     4.   All Funds: To consider a series of proposals to modify and/or
          eliminate certain investment restrictions of the Funds;

     5.   All Funds: To change the investment objective of the Funds from
          fundamental to non-fundamental; and

     6.   All Funds: To amend certain Funds' organizational documents.


Q: WHY ARE CERTAIN FUNDS ASKING FOR APPROVAL OF NEW ADVISORY CONTRACTS?

A: Since the advisory agreement for certain Funds inadvertently lapsed on April
17, 2000, shareholders of those Funds must approve new advisory agreements.
These agreements are virtually identical to the original agreement in content
and fee structure and are a simple continuation of the relationship between CSAM
and the Funds.

Q: WHY ARE CERTAIN FUNDS ASKING FOR APPROVAL OF RETENTION OF FEES PAID OR
PAYABLE TO CSAM?

A: Despite the inadvertent lapse of the original agreements, CSAM has continued
to provide the Funds with uninterrupted investment advisory services called for
under the original agreements. These Funds are simply seeking shareholder
approval to allow CSAM to retain all payments and be paid all unpaid amounts
over the past three years.

Q: WHY ARE CERTAIN FUNDS ASKING FOR APPROVAL OF A NEW DISTRIBUTION PLAN?

A: The Board, including a majority of the Independent Trustees (each of whom has
no direct or indirect financial interest in the operation of the Proposed
Distribution Plans or any agreements related to the Plans), unanimously approved
the Proposed Distribution Plans on December 12, 2002, subject to the approval of
the holders of shares of the applicable class(es) of each Fund.

The terms of the Proposed Distribution Plans will be essentially identical to
those of the plans that were previously adopted by the shareholders except that
the existing plans are "reimbursement"-type plans while the Proposed
Distribution Plans are "compensation"-type plans. The changes to a
compensation-type plan are expected to result in increases to the gross expense
ratio of certain classes of the Funds.

Q: WHY ARE THE FUNDS MAKING CHANGES TO CERTAIN INVESTMENT RESTRICTIONS AND
POLICIES?

A: CSAM and the Board of Directors/Trustees have reviewed each of the Fund's
current restrictions and have concluded that certain restrictions should be
removed or revised based upon new industry practices and changes in applicable
law. The modernization of these restrictions will maintain important investor
protections while providing flexibility to respond to changing markets, new
investment opportunities and future changes to applicable law.

The revised restrictions do not affect the investment objectives of the Funds,
which remain unchanged. The Funds will be managed in accordance with the
investment restrictions described in their Prospectuses, Statements of
Additional Information and in accordance with federal law.



Q: WHY ARE CSAM AND THE BOARDS REQUESTING TO CHANGE THE INVESTMENT OBJECTIVE TO
NON-FUNDAMENTAL?

A: This change would enhance a Fund's flexibility by allowing a Board to more
easily alter the Fund's investment objective when the Board believes it is in
the best interests of shareholders or when necessary to comply with possible
future regulatory changes. If approved by shareholders, this change would mean
that the Board would be able to change a Fund's investment objective in the
future without further shareholder approval. Fund shareholders would receive
prior notice of any change to a Fund's investment objective.

Q: DOES THE BOARD PLAN TO CHANGE THE INVESTMENT OBJECTIVES OF THE FUNDS?

A: The Boards have no current intention of changing any of the Fund's investment
objectives.

Q: WHAT ARE THE FUNDS' "ORGANIZATIONAL DOCUMENTS"?

A: Each Fund, like other mutual funds, is subject to comprehensive federal
regulation, particularly under the Investment Company Act of 1940. Additionally,
like other mutual funds, governance of each Fund is subject to the law of the
state in which the Fund is organized. Each Fund is organized either as a
Maryland corporation, a Massachusetts business trust or a Delaware statutory
trust, and therefore is subject to Maryland law, Massachusetts law or Delaware
law, respectively, as it applies to these entities.

An organizational document, also known as articles of incorporation or a
declaration of trust, as applicable, sets forth various provisions related to
governance of the corporation or the trust, respectively, and the authority of
the corporation or the trust to conduct its business within the state of
organization.

Q: WHY ARE THE FUNDS PROPOSING CHANGES TO THE ORGANIZATIONAL DOCUMENTS?

A: The changes to the organizational documents provide the Directors/Trustees
with more flexibility and broader authority than under the current
organizational document. This increased flexibility is intended to allow the
Directors/Trustees to react more quickly to changes in competitive and
regulatory conditions, and as a consequence, may allow the Funds to operate in a
more efficient and economical manner.

Although the amendments to the organizational document reduce or remove certain
shareholder voting and other rights (as more fully discussed in the proxy
statement), adoption of the amendments to the organizational document will not
affect any of the protections afforded to shareholders under federal law.

Q: WHERE CAN I GET MORE INFORMATION ABOUT THESE PROPOSALS?

A: The Funds have engaged Georgeson Shareholder Communications, Inc., a
professional proxy solicitation firm, to help shareholders through the voting
process. You or your clients may contact them directly at 1-866-825-6453 between
the hours of 9:30 a.m. to 11:00 p.m. eastern time. Representatives will be happy
to answer any questions you may have.
