CREDIT SUISSE NEW YORK MUNICIPAL FUND
SEMIANNUAL INVESTMENT ADVISER'S REPORT
April 30, 2003

                                                                    May 20, 2003

Dear Shareholder:

   For the six months ended April 30, 2003, the Common Class and Class A shares
of Credit Suisse New York Municipal Fund(1) (the "Fund") returned 2.82%(2) and
2.88%,(2) respectively, versus a gain of 3.51% for the Lehman Brothers 5 Year
Municipal Bond Index.(3)

   Although the Fund generated a positive return during the period, it did not
keep pace with its Lehman Brothers 5 Year Municipal Bond Index benchmark. In
general, this was due to our belief that a relatively defensive investment
stance was appropriate. It thus made sense to us to position the portfolio
conservatively.

   Accordingly, we maintained the overall approach we have taken in the Fund for
some time. Key aspects of our approach included:

   - We kept the portfolio's average maturity shorter than that of the
     benchmark, believing that this would help to reduce potential downside
     risk, given the uncertainty in the overall economy.

   - We continued to allocate a slightly higher degree of the portfolio to New
     York City paper than the benchmark does, based on our analysis that the
     risk of a downgrade in the City's debt rating was already reflected in the
     price of its bonds. New York City paper underperformed the benchmark,
     meaning that our above-benchmark allocation hurt relative performance.

   - We occasionally kept cash reserves at levels that were somewhat higher than
     normal, in anticipation of purchasing securities at valuations we deemed to
     be more attractive.

   Several factors helped our relative performance. We held a number of
securities that became prerefunded and escrowed in U.S. Treasury securities, and
their prices gained from the ensuing increase in their credit quality. In
addition, we owned premium-structured callable issues and raised the portfolio's
exposure to intermediate maturities, both of which benefited nicely in an
environment of rising interest-rate volatility. We also increased our holdings
of bonds with comparatively strong call protection and trimmed exposure to bonds
issued by Puerto Rico [note: Puerto Rico municipal debt is exempt from federal,
state and local taxes in all states], whose prices weakened in the period due to
rising worries about Puerto Rico's underlying creditworthiness.

                                        1
<Page>

   Our belief in an eventual economic recovery is intact and we intend to adhere
to the defensive investment stance we have described. Although we expect that
debt ratings for New York State and New York City may remain under pressure due
to budget-deficit concerns, we feel that a ratings downgrade is already
reflected in the prices of their respective securities. We have also built a
certain degree of flexibility into the portfolio that should allow us to take
advantage of price fluctuations and volatility.

   THE FUND'S DIVIDENDS ARE DERIVED FROM INTEREST ON NEW YORK MUNICIPAL
OBLIGATIONS THAT ARE EXEMPT FROM REGULAR FEDERAL INCOME TAXES AND FROM NEW YORK
STATE AND NEW YORK CITY PERSONAL INCOME TAXES. SOME INCOME FROM THE FUND THAT IS
EXEMPT FROM REGULAR FEDERAL TAXES MAY BE SUBJECT TO STATE AND CITY TAXES, AND
SOME INCOME MAY BE SUBJECT TO THE FEDERAL ALTERNATIVE MINIMUM TAX. THIS FUND MAY
BE MORE VOLATILE THAN A MORE GEOGRAPHICALLY DIVERSE MUNICIPAL FUND. IN THE
AFTERMATH OF THE TERRORIST ATTACK ON SEPTEMBER 11, 2001, ISSUERS OF MUNICIPAL
SECURITIES IN NEW YORK STATE AND NEW YORK CITY HAVE SUFFERED FINANCIAL
DIFFICULTIES, WHICH COULD ADVERSELY AFFECT THE ABILITY OF THOSE ISSUERS TO MAKE
PROMPT PAYMENTS OF PRINCIPAL AND INTEREST ON THEIR SECURITIES, AS WELL AS THE
CREDIT RATING, MARKET VALUE AND YIELD OF SUCH SECURITIES. THE DEFAULT OR
CREDIT-RATING DOWNGRADE OF ONE OF THESE ISSUERS COULD AFFECT THE MARKET VALUES
AND MARKETABILITY OF ALL MUNICIPAL SECURITIES, THEREBY HURTING THE FUND'S
PERFORMANCE. FURTHERMORE, IF THE FUND HAS DIFFICULTY FINDING ATTRACTIVE NEW YORK
MUNICIPAL SECURITIES TO PURCHASE, THE FUND MAY PURCHASE SECURITIES THAT PAY
INTEREST NOT EXEMPT FROM NEW YORK TAXES.

Note: Past performance is not predictive of future performance. Investment
return and principal value of an investment will fluctuate so that an investor's
shares upon redemption may be worth more or less than their original cost. The
performance results do not reflect the deduction of taxes that a shareholder
would pay on fund distributions or the redemption of fund shares.

- ----------
(1) Fee waivers and/or expense reimbursements reduced expenses for the Fund,
    without which performance would be lower. Waivers and/or reimbursements may
    be discontinued at any time.
(2) Total return for Class A shares for the reporting period based on offering
    price (with maximum sales charge of 3.00%) was down 0.17%.
(3) The Lehman Brothers 5 Year Municipal Bond Index is an unmanaged index (with
    no defined investment objective) of municipal bonds with maturities of
    between four and six years, and is calculated by Lehman Brothers, Inc.
    Investors cannot invest directly in an index.

- ----------
(1) Per share information is calculated using the average share outstanding
    method.

(2) Total returns are historical and assume changes in share price and
    reinvestments of all dividends and distributions. Had certain expenses
    not been reduced during the period shown, total returns would have been
    lower. Total returns for periods less than one year are not annualized.

(3) Interest earned on uninvested cash balances is used to offset portions of
    the transfer agent expense. These arrangements resulted in a reduction to
    the net expense ratio by .00%, .02%, .01%, and .00% for the years ended
    October 31, 2001, 2000, 1999 and 1998, respectively. The Common Class
    shares' net operating expense ratio after reflecting these arrangements
    was .60% for the years ended October 31, 2001, 2000, 1999, and 1998,
    respectively. For the six months ended April 30, 2003 and for the year
    ended October 31, 2002, there were no transfer agent credits.

(4) Annualized.

CREDIT SUISSE NEW YORK MUNICIPAL FUND
NOTES TO FINANCIAL STATEMENTS
April 30, 2003 (Unaudited)

NOTE 1. SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES

  Credit Suisse New York Municipal Fund, (the "Fund"), is registered under the
Investment Company Act of 1940, as amended (the "1940 Act"), as a
non-diversified open-end management investment company that seeks to maximize
current interest income exempt from regular federal income taxes, New York State
and New York City personal income taxes, to the extent consistent with prudent
investment management and the preservation of capital. The Fund was organized
under the laws of the Commonwealth of Massachusetts as a business trust on
December 23, 1986.

  The Fund is authorized to offer two classes of shares: Common Class and Class
A shares. Each class of shares represents an equal pro rata interest in the
Fund, except that they bear different expenses which reflect the difference in
the range of services provided to them. Effective December 12, 2001, the Common
Class closed to new investors. Common Class shares are not subject to
distribution fees. Class A shares are sold subject to a front-end sales charge
of up to 3.00% and bear expenses pursuant to a distribution plan at an annual
rate of 0.25% of the average daily net assets of the Fund's Class A shares. For
the period November 30, 2001 (inception date) through February 26, 2002 the
Class A shares were sold with a front-end sales charge of up to 4.75%. Effective
February 27, 2002, the front-end sales charge was reduced from 4.75% to 3.00%.

  A) SECURITY VALUATION -- The net asset value of the Fund is determined daily
as of the close of regular trading on the New York Stock Exchange, Inc. on each
day the Exchange is open for business. Debt securities with a remaining maturity
greater than 60 days are valued on the basis of broker quotations or valuations
provided by a pricing service which may use a matrix, formula or other objective
method that takes into consideration market indices, yield curves and other
specific adjustments. The Fund's equity investments are valued at market value,
which is generally determined using the closing price on the exchange or market
on which the security is primarily traded. If no sales are reported, equity
investments are generally valued at the most recent bid price. Securities and
other assets for which market quotations are not readily available are valued at
fair value as determined in good faith by the Board of Trustees under procedures
established by the Board of Trustees in the absence of readily ascertainable
market values. Debt obligations that will mature in 60 days or less are valued
on the basis of amortized cost, which approximates market value, unless the
Board of Trustees determines that using this method would not reflect an
investment's fair value.

                                       13
<Page>

  B) SECURITY TRANSACTIONS AND INVESTMENT INCOME -- Security transactions are
accounted for on a trade date basis. Interest income is recorded on the accrual
basis. Dividends are recorded on the ex-dividend date. Income, expenses
(excluding class-specific expenses) and realized/unrealized gains/losses are
allocated proportionately to each class of shares based upon the relative net
asset value of outstanding shares of that class. The cost of investments sold is
determined by the use of specific identification method for both financial
reporting and income tax purposes.

  C) DIVIDENDS AND DISTRIBUTIONS TO SHAREHOLDERS -- Dividends from net
investment income are declared daily and paid monthly. Distributions of net
realized capital gains, if any, are declared and paid at least annually.
However, to the extent that a net realized capital gain can be reduced by a
capital loss carryover, such gain will not be distributed. Income and capital
gain distributions are determined in accordance with federal income tax
regulations which may differ from accounting principles generally accepted in
the United States of America ("GAAP").

  D) FEDERAL INCOME TAXES -- No provision is made for federal taxes as it is the
Fund's intention to continue to qualify for and elect the tax treatment
applicable to regulated investment companies under the Internal Revenue Code of
1986, as amended, and make the requisite distributions to its shareholders which
will be sufficient to relieve it from federal income and excise taxes.

  E) USE OF ESTIMATES -- The preparation of financial statements in conformity
with GAAP requires management to make estimates and assumptions that affect the
reported amounts of assets and liabilities and disclosure of contingent assets
and liabilities at the date of the financial statements and the reported amounts
of revenues and expenses during the reporting period. Actual results could
differ from these estimates.

  F) SHORT-TERM INVESTMENTS -- The Fund, together with other funds/portfolios
advised by Credit Suisse Asset Management, LLC ("CSAM"), an indirect,
wholly-owned subsidiary of Credit Suisse Group, pool available cash into a
short-term time deposit issued by State Street Bank and Trust Company ("SSB"),
the Fund's custodian. The short-term time deposit is a variable rate account
classified as a short-term investment.

  G) SECURITIES LENDING -- Loans of securities are required at all times to be
secured by collateral at least equal to 102% of the market value of domestic
securities on loan including any accrued interest thereon and 105% of the market
value of foreign securities on loan including any accrued interest thereon. Cash
collateral received by the Fund in connection with securities lending activity
may be invested in a variety of investments including

                                       14
<Page>

certain CSAM-advised funds or the AIM Institutional Funds - Liquid Asset
Portfolio. However, in the event of default or bankruptcy by the other party to
the agreement, realization and/or retention of the collateral may be subject to
legal proceedings. The Fund had no securities out on loan during the six months
ended April 30, 2003.

  Credit Suisse First Boston ("CSFB"), an affiliate of CSAM, has been engaged by
the Fund to act as the Fund's securities lending agent. Prior to April 1, 2003,
CSFB had agreed to charge the Fund fees for its securities lending activities
equal to its costs in providing services as sercurities lending agent and had
voluntarily waived such fees through March 31, 2003. Effective April 1, 2003,
the Fund and CSFB entered into an arrangement to share the income earned from
securities lending activities, whereby, generally, the Fund will receive 75% and
CSFB will receive 25% of the income, in accordance with the provisions of the
securities lending agency agreement. If CSFB should enter into a securities
lending agency agreement with another comparable investment company client under
which it will receive a smaller proportion of the fees, its fee agreement with
the Fund shall be reduced to such lower fee amount.

  H) OTHER -- The interest on New York municipal obligations is excluded from
gross income for federal income tax purposes and exempt from New York state and
New York City personal income taxes. A portion of income may be subject to state
and City taxes or the federal alternative minimum tax. This Fund may be riskier
than a more geographically-diverse municipal fund.

distribution services. This fee is calculated at an annual rate of 0.25% of the
average daily net assets of the Class A shares. For the six months ended April
30, 2003, distribution fees earned by CSAMSI were $859.

  Certain brokers, dealers and financial representatives provide transfer agent
related services to the Fund, and receive compensation for these services from
CSAM. CSAM is then reimbursed by the Fund. For the six months ended April 30,
2003, the Fund reimbursed CSAM $18,616, which is included in the Fund's transfer
agent expense.

Fund.

NOTE 3. LINE OF CREDIT

the "Participating Funds"), participates in a $150 million committed, unsecured
line of credit facility ("Credit Facility") with Deutsche Bank, A.G. as
administrative agent and syndication agent and SSB as operations agent for
temporary or emergency purposes. Under the terms of the Credit Facility, the
Participating Funds pay an aggregate commitment fee at a rate of 0.10% per annum
on the average unused amount of the Credit Facility, which is allocated among
the Participating Funds in such manner as is determined by the governing Boards
of the Participating Funds. In addition, the Participating Funds pay interest on
borrowings at the Federal Funds rate
