CREDIT SUISSE FIXED INCOME FUND
PORTFOLIO MANAGER'S LETTER
April 30, 2002


                                                                    May 28, 2002

Dear Shareholder:

    For the six months ended April 30, 2002, the Class A (without sales
charge)(1), Class B (without contingent deferred sales charge)(1), and Class C
(without contingent deferred sales charge)(1) shares of Credit Suisse Fixed
Income Fund(2) (the "Fund") were down 1.83%, 2.19% and 2.19%, respectively, vs.
a decline of 0.01% for the Lehman Brothers Aggregate Bond Index.(3)

    The period was an overall lackluster one for bonds, though performance
varied by market segment. Treasury securities, often highly sensitive to moves
in interest rates, were hindered by fears that the Federal Reserve (the "Fed")
would begin to lift rates from historically low levels. Investment-grade
corporate bonds fared somewhat better, aided by signs of an improving economy
but also restrained by fears of "other Enrons."

    Elsewhere, mortgage-backed securities (MBS), commercial MBS (CMBS) and
asset-backed securities (ABS) had relatively good performance. MBS benefited
from a receding wave of refinancing activity, while CMBS and ABS drew support
from signs of an improving economy. One area of strong performance in the period
was high-yield corporate debt, though the group was fairly volatile.

    In this environment, the Fund had a loss and lagged its benchmark. Bonds
that hampered the Fund included certain corporate holdings -- e.g., specific
telecom and industrial bonds -- as well as its Argentine securities (we exited
our position in Argentina in the period). One factor that contributed positively
to the Fund's return was its significant exposure to high-yield corporate
issues, which accounted for about 8.75% of the Fund as of April 30.

    Looking ahead, we are optimistic regarding the prospects for non-Treasury
bonds such as corporate and mortgage-backed issues, and intend to maintain
sizable positions in those sectors. We believe that a number of factors should
support these bonds, foremost the economy's emerging recovery, which should
prove to be a net positive for credit quality; the Fed's apparent unwillingness
to sharply raise rates; aggressive efforts by many companies to cut costs and
de-leverage their balance sheets; and an improving trend in corporate
fundamentals. We also believe that, sooner rather that later, investors' worries
over Enron-type accounting problems will begin to fade.

    With specific regard to high-yield securities, we currently view valuations
here as appealing, and believe that the group's default rate will peak in 2002
and begin to decline, assuming the economy continues to rebound. As with


                                       1
<Page>

our approach to investment-grade corporate bonds, we plan to continue to
strictly limit high-yield position sizes while maintaining a high degree of
diversification. We have become more cautious regarding emerging-market debt,
where valuations have risen to the point at which we feel they no longer provide
reasonable compensation for downside risk.

CREDIT SUISSE FIXED INCOME FUND
NOTES TO FINANCIAL STATEMENTS
April 30, 2002 (Unaudited)


NOTE 1. SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES

    Credit Suisse Fixed Income Fund, formerly the Credit Suisse Warburg Pincus
Fixed Income Fund (the "Fund"), a Massachusetts Business Trust, is registered
under the Investment Company Act of 1940, as amended (the "1940 Act"), as a
diversified open-end management investment company that seeks to generate high
current income consistent with reasonable risk and, secondarily, capital
appreciation.

    The Fund is authorized to offer five classes of shares: Common Class,
Advisor Class, Class A, Class B, and Class C shares. Each class of shares
represents an equal pro rata interest , 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. Advisor
Class shares bear expenses paid pursuant to a distribution plan adopted by the
Fund at an annual rate not to exceed .75% of the average daily net asset value
of the Fund's outstanding Advisor Class shares. Advisor Class shares currently
bear expenses of .25% of average daily net assets. Class A shares are sold
subject to a front-end sales charge of 4.75% and bear expenses paid pursuant to
a shareholder servicing and distribution plan at an annual rate of .25% of the
average daily net asset value of the Fund's Class A shares. Class B shares are
sold subject to a contingent deferred sales charge which declines from 4% to
zero depending on the period of time the shares are held and bear expenses paid
pursuant to a shareholder servicing and distribution plan at an annual rate of
1.00% of the average daily net asset value of the Fund's Class B shares. Class C
shares are sold subject to a contingent deferred sales charge of 1% if redeemed
within the first year of purchase and bear expense paid pursuant to a
shareholder servicing and distribution plan at an annual rate of 1.00% of the
average daily net asset value of the Fund's Class C shares. Results for the
Common Class and Advisor Class shares are contained in a separate book.

    Effective as of the close of business on April 6, 2001, the Fund acquired
all of the net assets of the Credit Suisse Warburg Pincus Fixed Income II Fund
("Fixed Income II") in a tax-free exchange of shares. The shares exchanged were
9,206,012 shares (valued at $93,738,572) of the Common Class of the Fund for
9,152,071 shares of Class D of Fixed Income II, 3,550,971 shares (valued at
$36,153,007) of the Advisor Class of the Fund for 3,530,165 shares of Class A of
Fixed Income II, 323,384 shares (valued at $3,292,431) of the Advisor Class of
the Fund for 321,489 shares of Class B of Fixed Income II, and 14,919 shares
(valued at $151,823) of the Advisor Class of the Fund for 14,817 shares of Class
D of Fixed Income II. The Fixed Income II net assets of $133,335,834 at that
date, which included $2,388,035 of unrealized appreciation, were combined with
those of the Fund. The aggregate net assets of Fixed Income II and the


                                       23

Fund immediately before the acquisition were $133,335,834 and $339,752,048,
respectively and the combined net assets of the Fund were $473,087,882.

    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. The
Fund's investments are valued at market value, which is generally determined
using the last reported sales price. If no sales are reported, investments are
generally valued at the last reported bid price and if there is no bid price
available, at the most recent ask price. Debt securities 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, matrices, yield curves and other specific adjustments. If market
quotations are not readily available, securities and other assets are valued by
another method that the Fund's Board of Trustees believe accurately reflects
fair value. Debt obligations that will mature in 60 days or less are valued on
the basis of amortized cost, unless the Board determines that using this method
would not reflect an investment's value.

    B) FOREIGN CURRENCY TRANSACTIONS -- The books and records of the Fund are
maintained in U.S. dollars. Transactions denominated in foreign currencies are
recorded at the current prevailing exchange rates. All assets and liabilities
denominated in foreign currencies are translated into U.S. dollar amounts at the
current exchange rate at the end of the period. Translation gains or losses
resulting from changes in the exchange rate during the reporting period and
realized gains and losses on the settlement of foreign currency transactions are
reported in the results of operations for the current period. The Fund does not
isolate that portion of realized gains and losses on investments in equity
securities which is due to changes in the foreign exchange rate from that which
is due to changes in market prices of equity securities. The Fund isolates that
portion of realized gains and losses on investments in debt securities which is
due to changes in the foreign exchange rate from that which is due to changes in
market prices of debt securities.

    C) SECURITY TRANSACTIONS AND INVESTMENT INCOME-- Security transactions are
accounted for on a trade date basis. Interest income is recorded on the accrual
basis. The Fund amortizes premium and accretes discount using the effective
interest method. Dividends are recorded on the ex-dividend date. Certain
expenses are class specific expenses and vary by class. Income, expenses
(excluding class-specific expenses, principal distribution and shareholder
servicing fees) and realized/unrealized gains/losses are allocated
proportionately to each class of shares based upon the relative net asset
valueof the outstanding shares of that class. The cost of investments sold is
determined


                                       24
<Page>

by use of the specific identification method for both financial reporting and
income tax purposes.

    Effective November 1, 2001, the Fund adopted the revised AICPA Audit and
Accounting Guide, Audits of Investment Companies and began to classify gains and
losses on paydowns of mortgage- and asset-backed securities presently included
in realized gain and losses, as a component of interest income. The effect of
this change for the six months ended April 30, 2002, to the Fund was to increase
net investment income by $4,767 and to decrease net realized gains (losses) by
$4,767. These reclassifications had no impact on net assets or net asset value
per share. The statements of changes in net assets and the financial highlights
for all prior periods shown have not been restated to reflect this change.

    D) 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").

    E) 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.

    F) 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 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.

    G) SHORT-TERM INVESTMENTS -- The Fund, together with other funds 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 & Trust, the Fund's custodian. The
short-term time deposit is a variable rate account classified as a short-term
investment.


                                       25

    H) TBA PURCHASE COMMITMENTS -- The Fund may enter into "TBA" (to be
announced) purchase commitments to purchase securities for a fixed price at a
future date, typically not exceeding 45 days. TBA purchase commitments may be
considered securities in themselves, and involve a risk of loss if the value of
the security to be purchased declines prior to settlement date. This risk is in
addition to the risk of decline in the Fund's other assets. Unsettled TBA
purchase commitments are valued at the current market value of the underlying
securities, according to the procedures described under "Security Valuation"
above.

    I) FORWARD FOREIGN CURRENCY CONTRACTS -- The Fund may enter into forward
foreign currency contracts for the purchase or sale of a specific foreign
currency at a fixed price on a future date. Risks may arise upon entering into
these contracts from the potential inability of counter-parties to meet the
terms of their contracts and from unanticipated movements in the value of a
foreign currency. The Fund will enter into forward foreign currency contracts
primarily for hedging purposes. Forward foreign currency contracts are adjusted
by the daily exchange rate of the underlying currency and any gains or losses
are recorded for financial statement purposes as unrealized until the contract
settlement date, or an offsetting position is entered into. At April 30, 2002,
the Fund had no open forward foreign currency contracts.

    J) 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
is invested in 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, 2002.

    Credit Suisse First Boston ("CSFB"), an affiliate of CSAM, has been engaged
by the Fund to act as the Fund's securities lending agent. Pending receipt of an
exemption from the Securities and Exchange Commission ("SEC"), CSFB has agreed
to charge the Fund fees for its securities lending activities equal to its costs
in providing services as securities lending agent. CSFB also has voluntarily
agreed to waive its fees for the securities lending agent services that it
provides. CSFB may discontinue its voluntary fee waivers at any time.


                                       26

    K) OTHER -- The Fund may invest in securities of foreign countries and
governments, which involve certain risks in addition to those inherent in
domestic investments. Such risks generally include, among other things, currency
risk (fluctuations in currency exchange rates), information risk (key
information may be inaccurate or unavailable) and political risk (expropriation,
nationalization or the imposition of capital or currency controls or punitive
taxes). Other risks of investing in foreign securities include liquidity and
valuation risks.

    The Fund may be subject to taxes imposed by countries in which they invest,
with respect to their investments in issuers existing or operating in such
countries. Such taxes are generally based on income earned or repatriated and
capital gains realized on the sale of such investments. The Fund accrues such
taxes when the related income or capital gains are earned.

    The Fund's investments in securities of issuers located in less developed
countries considered to be "emerging markets" involve risks in addition to those
generally applicable to foreign securities. Focusing on emerging (less
developed) markets involves higher levels of risk, including increased currency,
information, liquidity, market, political and valuation risks. Deficiencies in
regulatory oversight, market infrastructure, shareholder protections and company
laws could expose the Fund to operational and other risks as well. Some
countries may have restrictions that could limit the Fund's access to attractive
opportunities. Additionally, emerging markets often face serious economic
problems (such as high external debt, inflation and unemployment) that could
subject the portfolio to increased volatility or substantial declines in value.

    Lower-rated debt securities (commonly known as "junk bonds") possess
speculative characteristics and are subject to greater market fluctuations and
risk of lost income and principal than higher-rated debt securities for a
variety of reasons. Also, during an economic downturn or substantial period of
rising interest rates, highly leveraged issuers may experience financial stress
which would adversely effect their ability to service their principal and
interest payment obligations, to meet projected business goals and to obtain
additional financing.

    In addition, periods of economic uncertainty and changes can be expected to
result in increased volatility of market prices of lower-rated debt securities
and (to the extent a Fund invests in junk bonds) the Fund's net asset value.


                                       27
<Page>

    The Fund may invest up to 15% of its net assets in non-publicly traded
securities. Non-publicly traded securities may be less liquid than
publicly-traded securities, and they may be difficult or impossible to sell at
the time and at the price the Fund would like. In addition, the lack of an
active market may make it difficult to obtain an accurate price for a Fund's
security.


NOTE 2. TRANSACTIONS WITH AFFILIATES AND RELATED PARTIES

    CSAM serves as investment adviser for the Fund. For its investment advisory
services, CSAM is entitled to receive a fee from the Fund at an annual rate of
..50% of the Fund's average daily net assets. For the six months ended April 30,
2002, investment advisory fees earned and voluntarily waived were $856,240 and
$310,146, respectively.

    Credit Suisse Asset Management Securities, Inc. ("CSAMSI"), an affiliate of
CSAM, and PFPC, Inc. ("PFPC"), an indirect, wholly-owned subsidiary of PNC
Financial Services Group, serve as the Fund's co-administrators. For its
administrative services, CSAMSI, currently receives a fee calculated at an
annual rate of .10% of the Fund's average daily net assets. For the six months
ended April 30, 2002, administrative services fees earned by CSAMSI were
$171,248.

    For its administrative services through April 30, 2002, PFPC is entitled to
receive a fee, exclusive of out-of-pocket expenses, based on the following fee
structure:

         First $150 million                                  .07% of average daily net assets
         Second $150 million                                 .06% of average daily net assets
         Over $300 million                                   .05% of average daily net assets
</Table>

    For the six months ended April 30, 2002, administrative services fees earned
by PFPC (including out-of-pocket expenses) were $126,067.

    At its meeting held on February 12, 2002, the Board of Trustees adopted a
resolution to approve a Co-Administrator Agreement between the Fund and State
Street Bank and Trust Company ("SSB") to replace PFPC effective mid 2002.

    In addition to serving as the Fund's co-administrator, CSAMSI serves as
distributor of the Fund's shares. Pursuant to a distribution plan adopted by the
Fund pursuant to Rule 12b-1 under the 1940 Act, CSAMSI receives a fee for its
distribution services. This fee is calculated at an annual rate of .25% of the
average daily net assets of the Advisor Class and Class A shares. For Class B
and Class C shares of the Fund, the fee is calculated at an annual rate of 1.00%
of average daily net assets of the Class B and Class C shares of the Fund.
CSAMSI may use this fee to compensate service organizations for


                                       28

    Certain brokers, dealers and financial representatives provide transfer
agent related services to the Fund, and receive compensation from CSAM. CSAM is
then reimbursed by the Fund. For the six months ended April 30, 2002, the Fund
reimbursed CSAM $106,026, which is included in the Fund's transfer agent
expense.

    For the six months ended April 30, 2002, CSAMSI and its affiliates advised
the Fund that it retained $22,516 from commissions earned on the sale of the
Funds' shares.

    Merrill Corporation ("Merrill"), an affiliate of CSAM, has been engaged by
the Fund to provide certain financial printing services. For the six months
ended April 30, 2002, Merrill was paid $33,528 for its services to the Fund.


NOTE 3. LINE OF CREDIT

    Through June 18, 2002, the Fund, together with other funds advised by CSAM
(collectively, the "Participating Funds"), participated in a $200 million
committed, unsecured line of credit facility ("Prior Credit Facility") with
Deutsche Bank, A.G. as administrative agent, State Street Bank and Trust Company
as operations agent, BNP Paribas as syndication agent and certain other lenders
for temporary or emergency purposes primarily relating to unanticipated
Participating Funds' share redemptions. Under the terms of the Prior Credit
Facility, the Participating Funds pay an aggregate commitment fee at a rate of
..10% per annum on the average unused amount of the Prior Credit Facility, which
is allocated among the Participating Funds in such a manner as was determined by
the governing Boards of the Participating Funds. In addition, the Participating
Funds paid interest on borrowings at the Federal funds rate plus .50%. For the
six months ended April 30, 2002, the Fund had no borrowings under the Prior
Credit Facility.


                                       29
<Page>

    Effective June 19, 2002, the Participating Funds, together with additional
funds advised by CSAM (collectively with the Participating Funds, the "New
Participating Funds"), established a new $150 million committed, unsecured, line
of credit facility (the "New Credit Facility") with Deutsche Bank, A.G. as
administrative agent and syndication agent and State Street Bank and Trust
Company as operations agent for the same purposes as the Prior Credit Facility.
Terms of the New Credit Facility remain the same as the Prior Credit Facility.
The commitment fee rate and interest paid is unchanged.


NOTE 4. PURCHASES AND SALES OF SECURITIES

    For the six months ended April 30, 2002, purchases and sales of investment
securities (excluding short-term investments) and U.S. government and agency
obligations were $106,686,358 and $121,166,591, $704,413,352 and $720,643,314,
respectively.

    At April 30, 2002, the gross unrealized appreciation from investments for
those securities having an excess of value over cost, gross unrealized
depreciation from investments for those securities having an excess of cost over
value and net unrealized depreciation from investments (based on cost for
federal income tax purposes) were $6,400,041, $12,616,015 and $6,215,974,
respectively.


NOTE 5. CAPITAL SHARE TRANSACTIONS

    The fund is authorized to issue an unlimited number of full and fractional
shares of beneficial interest, $.001 par value per share, of which an unlimited

NOTE 6. FUTURES CONTRACTS

    The Fund may enter into futures contracts to the extent permitted by its
investment policies and objectives. Upon entering into a futures contract, the
Fund is required to deposit cash or pledge U.S. Government securities of an
initial margin with its custodian in a segregated account. Subsequent payments,
which are dependent on the daily fluctuations in the value of the underlying
instrument, are made or received by the Fund each day (daily variation margin)
and are recorded as unrealized gains or losses until the contracts are closed.
When the contract is closed, the Fund records a realized gain or loss equal to
the difference between the proceeds from (or cost of) the closing transactions
and the Fund's basis in the contract. Risks of entering into futures contracts
for hedging purposes include the possibility that a change in the value of the
contract may not correlate with the changes in the value of the underlying
instruments. In addition, the purchase of a futures contract involves the risk
that the Fund could lose more than the original margin deposit and subsequent
payments required for a futures transaction. At April 30, 2002, the Fund had the
following open futures contracts:
