Dear Shareholder:

Performance Summary

11/01/05 – 04/30/06

Fund & Benchmark	Performance
Common Class¹		0.26	%
Advisor Class¹		(0.01	)%
Class A^{1, 2}		0.11	%
Class B^{1, 2}		(0.21	)%
Class C^{1, 2}		(0.21	)%
Lehman Brothers US Aggregate Bond Index³		0.56	%

Performance for the Fund's Class A, Class B and Class C Shares is without the maximum sales charge of 4.75%, 4.00% and 1.00%, respectively.²

Market Overview: Rates continue to rise

The period was a slightly positive one for the US investment grade bond market in terms of total return, though bond prices were restrained by rising interest rates. The Federal Reserve continued its campaign to raise rates in small but steady increments, with the federal funds rate reaching 4.75% by the end April 2006, up from 3.75% at the start of the period and 1.00% in June 2004.

The economy continued its growth trajectory despite the increase in interest rates (which can have a lagging effect on growth) along with higher energy costs. First quarter 2006 GDP rose at nearly a 5% annual rate, its highest quarterly rate in more than two years. Inflation remained within the Fed's comfort zone, but as of the end of the period was closer to its upper level of 2%, as measured by personal consumption expenditures. The best performing bonds in this environment tended to be lower-quality securities such as non-investment-grade corporate debt and emerging market bonds.

Strategic Review: Focus on issuer fundamentals

The Fund trailed its benchmark, despite our generally cautious approach to interest-rate risk (staying neutral to short with regard to the Portfolio's duration). We attribute this largely to the Fund's exposure to longer-dated corporate BBB rated bonds such as home builders. This was disappointing, as those holdings had mostly delivered on our optimistic industry and company-specific assumptions. For example, the underperformance of our home builder companies occurred despite a strong construction market, healthy earnings reports and upwardly revised earnings forecasts. In our view, these positives

were countered by investor concerns over companies' shareholder-friendly uses of capital, with debt reduction less of a priority in many corporations.

In terms of noteworthy portfolio adjustments, we opted to lower our weighting in BBB rated corporate bonds, ending the period with a slight underweighting in the category, versus an overweighting we held in late 2005. While we continue to view corporate bonds as more compelling than Treasuries from a total return perspective, we have adopted a more neutral approach to lower-rated corporate securities based on financial trends within corporations. These include increased merger and acquisition activity, along with an ongoing corporate preference for equity-shareholder friendly actions such as stock buybacks and higher dividends, as companies try to turn excess corporate cash into higher share prices.

We continue to believe that attractive bonds exist among BBB rated corporates, but we also think that a highly selective approach is appropriate, and we remain focused on a bottom-up, fundamentals based strategy. We also continue to focus on asset-backed, commercial mortgage-backed securities and below-investment-grade corporate bonds for their diversification characteristics and total-return potential.

Fixed income investing entails credit risks and interest rate risks. Typically, when interest rates rise, the market value of fixed income securities generally declines and the share price of the Fund can fall.

In addition to historical information, this report contains forward-looking statements, which may concern, among other things, domestic and foreign market, industry and economic trends and developments and government regulation and their potential impact on the Fund's investments. These statements are subject to risks and uncertainties and actual trends, developments and regulations in the future and their impact on the Fund could be materially different from those projected, anticipated or implied. The Fund has no obligation to update or revise forward-looking statements.

Returns represent past performance and include change in share price and reinvestment of dividends and capital gains. Past performance cannot guarantee future results. The current performance of the Fund may be lower or higher than the figures shown. Returns and share price will fluctuate, and redemption value may be less than 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. Performance information current to the most recent month-end is available at www.credit-suisse.com/us.

¹ Fee waivers and/or expense reimbursements may reduce expenses for the Fund, without which performance would be lower. Waivers and/or reimbursements may be discontinued at any time.

² Total return for the Fund's Class A shares for the reporting period, based on offering price (with maximum sales charge of 4.75%), was down 4.67%.

Information About Your Fund's Expenses

As an investor of the Fund, you incur two types of costs: ongoing expenses and transaction costs. Ongoing expenses include management fees, distribution and service (12b-1) fees and other Fund expenses. Examples of transaction costs include sales charges (loads), redemption fees and account maintenance fees, which are not shown in this section and which would result in higher total expenses. The following table is intended to help you understand your ongoing expenses of investing in the Fund and to help you compare these expenses with the ongoing expenses of investing in other mutual funds. The table is based on an investment of $1,000 made at the beginning of the six month period ended April 30, 2006.

The table illustrates your Fund's expenses in two ways:

• Actual Fund Return. This helps you estimate the actual dollar amount of ongoing expenses paid on a $1,000 investment in the Fund using the Fund's actual return during the period. To estimate the expenses you paid over the period, simply divide your account value by $1,000 (for example, an $8,600 account value divided by $1,000 = 8.6), then multiply the result by the number in the "Expenses Paid per $1,000" line under the share class you hold.

• Hypothetical 5% Fund Return. This helps you to compare your Fund's ongoing expenses with those of other mutual funds using the Fund's actual expense ratio and a hypothetical rate of return of 5% per year before expenses. Examples using a 5% hypothetical fund return may be found in the shareholder reports of other mutual funds. The hypothetical account values and expenses may not be used to estimate the actual ending account balance or expenses you paid for the period.

Please note that the expenses shown in these tables are meant to highlight your ongoing expenses only and do not reflect any transaction costs, such as sales charges (loads) or redemption fees. If these transaction costs had been included, your costs would have been higher. The "Expenses Paid per $1,000" line of the tables is useful in comparing ongoing expenses only and will not help you determine the relative total expenses of owning different funds.

Annualized Expense Ratios*		0.70	%		1.20	%		0.95	%		1.70	%		1.70	%

* Expenses are equal to the Fund's annualized expense ratio for each share class, multiplied by the average account value over the period, multiplied by the number of days in the most recent fiscal half year period, then divided by 365.

The "Expenses Paid per $1,000" and the "Annualized Expense Ratios" in the tables are based on actual expenses paid by the Fund during the period, net of fee waivers and/or expense reimbursements. If those fee waivers and/or expense reimbursements had not been in effect, the Fund's actual expenses would have been higher.

Credit Suisse Fixed Income Fund

Notes to Financial Statements

April 30, 2006 (unaudited)

Note 1. Organization

Credit Suisse Fixed Income Fund (the "Fund"), 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 was organized under the laws of the Commonwealth of Massachusetts as a business trust on January 20, 1987.

The Fund is authorized to offer five classes of shares: Common Class shares, Advisor Class shares, Class A shares, Class B shares, and Class C shares. Each class of shares represents an equal pro rata interest in the Fund, except that they bear different expenses which reflect the differences in the range of services provided to them. The Fund's Common Class shares are closed to new investors, other than (1) investors in employee retirement, stock, bonus, pension or profit-sharing plans, (2) investment advisory clients of Credit Suisse Asset Management, LLC ("Credit Suisse"), (3) certain registered investment advisers ("RIAs"), (4) certain broker-dealers and RIAs with clients participating in comprehensive fee programs (5) employees of Credit Suisse or its affiliates and current and former Directors or Trustees of funds advised by Credit Suisse or its affiliates and (6) Credit Suisse or its affiliates. Any Common Class shareholder as of the close of business on December 12, 2001 can continue to buy Common Class shares of the Fund and open new accounts under the same Social Security number. Class A shares are sold subject to a front-end sales charge of up to 4.75%. Class B shares are sold subject to a contingent deferred sales shares which declines from 4.00% to zero depending on the period of time the shares are held. Class C shares are sold subject to a contingent deferred sales charge of 1.00% if redeemed within the first year of purchase.

Note 2. Significant Accounting Policies

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 "Exchange") on each day the Exchange is open for business. Debt securities with a remaining maturity greater than 60 days are valued in accordance with the price supplied 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. Debt obligations that will mature in 60 days or less are valued on the basis of amortized cost, which approximates market value, unless it is determined that using this method would not represent fair value. 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 at the time of valuation (the

Credit Suisse Fixed Income Fund

Notes to Financial Statements (continued)

April 30, 2006 (unaudited)

Note 2. Significant Accounting Policies

"Valuation Time"). If no sales are reported, equity investments are generally valued at the most recent bid quotation as of the Valuation Time or at the lowest asked quotation in the case of a short sale of securities. Investments in mutual funds are valued at the mutual fund's closing net asset value per share on the day of valuation. Securities and other assets for which market quotations are not readily available, or whose values have been materially affected by events occurring before the Fund's Valuation Time but after the close of the securities' primary markets, are valued at fair value as determined in good faith by, or under the direction of, the Board of Trustees under procedures established by the Board of Trustees. The Fund may utilize a service provided by an independent third party which has been approved by the Board of Trustees to fair value certain securities. When fair-value pricing is employed, the prices of securities use d by a fund to calculate its net asset value may differ from quoted or published prices for the same securities.

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. Dividends are recorded on the ex-dividend date. Certain expenses are class-specific expenses and vary by class. 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 the outstanding shares of that class. The cost of investments sold is determined by use of the specific identification method for both financial reporting and income tax purposes.

D) DIVIDENDS AND DISTRIBUTIONS TO SHAREHOLDERS — Dividends from net investment income are declared daily and paid monthly.

Credit Suisse Fixed Income Fund

Notes to Financial Statements (continued)

April 30, 2006 (unaudited)

Note 2. Significant Accounting Policies

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 carry forward, 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 to 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 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.

G) SHORT-TERM INVESTMENTS — The Fund, together with other funds/portfolios advised by Credit Suisse, an indirect, wholly-owned subsidiary of Credit Suisse Group, pools available cash into either a short-term variable rate time deposit issued by State Street Bank and Trust Company ("SSB"), the Fund's custodian, or a money market fund advised by Credit Suisse. The short-term time deposit issued by SSB is a variable rate account classified as a short-term investment.

H) 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 counterparties 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, 2006, the Fund had no open forward foreign currency contracts.

I) 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

Credit Suisse Fixed Income Fund

Notes to Financial Statements (continued)

April 30, 2006 (unaudited)

Note 2. Significant Accounting Policies

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.

J) FUTURES — 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 as initial margin. 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 contracts are 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 contracts. 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, 2006, the Fund had the following open futures contracts:

Futures Contracts	Number of Contracts			Expiration Date	Contract Amount			Contract Value			Unrealized Appreciation/ (Depreciation)
Government of Canada 10 Year Bonds Futures		24		6/21/06	$	2,414,339		$	2,361,340		$	(52,999	)

Note 2. Significant Accounting Policies

K) OPTIONS — The Fund may purchase and write (sell) call and put options on securities, currencies and swap agreements (options on swap agreements are commonly known as "swaptions"). The Fund may write covered and uncovered put and call options and purchase put and call options for hedging purposes or to increase total return. The risk associated with purchasing an option is that the Fund pays a premium whether or not the option is exercised. Additionally, the Fund bears the risk of loss of premium and change in market value should the counterparty not perform under the contract. Put and call options purchased are accounted for in the same manner as portfolio securities. The cost of securities acquired through the exercise of call options is increased by the premium paid. The proceeds from securities sold through the exercise of put options are decreased by the premium paid.

When the Fund writes an option, the premium received by the Fund is recorded as a liability and is subsequently adjusted to the current market value of the option written. Premiums received from writing options that expire unexercised are recorded by the Fund on the expiration date as realized gains from options transactions. The difference between the premium received and the amount paid on effecting a closing purchase transaction, including brokerage commissions, is also treated as a realized gain, or if the premium received is less than the amount paid for the closing purchase transaction, as a realized loss. If a call option is exercised, the premium received is added to the proceeds from the sale of the underlying security in determining whether the Fund has realized a gain or loss. If a put option is exercised, the premium received reduces the cost basis of the security purchased by the Fund. The risk involved in writing an option is t hat, if the option is exercised, the underlying security could then be purchased or sold by the Fund at a disadvantageous price. Uncovered options are riskier than covered options because there is no underlying security held by the Fund that can act as a partial hedge. Uncovered calls have speculative characteristics and the potential for loss is unlimited. There is also a risk that the securities on which the option is written may not be available for purchase if the call option is exercised. Uncovered put options have speculative characteristics and the potential loss is substantial.

Exchange-traded options are valued at the last sale price in the market where such contracts are principally traded. OTC equity index options are priced according to the contract specifications (days to expiration, current spot index level, interest rates, dividends, strike price) using the Black-Scholes pricing model, modified for dividends. The volatility input assumption is interpolated from the previous day's price. At April 30, 2006 the Fund had no outstanding options contracts.

Note 2. Significant Accounting Policies

L) SWAPS — The Fund may enter into index swaps for hedging purposes or to seek to increase total return. A swap is an agreement that obligates two parties to exchange a series of cash flows at specified intervals based upon or calculated by reference to changes in specified prices or rates for a specified amount of an underlying asset or notional principal amount. The Fund will enter into index swaps only on a net basis, which means that the two payment streams are netted out, with the Fund receiving or paying, as the case may be, only the net amount of the two payments. Risks may arise as a result of the failure of the counterparty to the swap contract to comply with the terms of the swap contract. The loss incurred by the failure of a counterparty is generally limited to the net interest payment to be received by the Fund, and/or the termination value at the end of the contract. Therefore, the Fund considers the creditworthiness of ea ch counterparty to a swap contract in evaluating potential credit risk. Additionally, risks may arise from unanticipated movements in interest rates or in the value of the underlying reference asset or index.

The Fund records unrealized gains or losses on a daily basis representing the value and the current net receivable or payable relating to open swap contracts. Net amounts received or paid on the swap contract are recorded as realized gains or losses. Fluctuations in the value of swap contracts are recorded for financial statement purposes as unrealized appreciation or depreciation of swap contracts. Realized gains and losses from terminated swaps are included in net realized gains/losses on swap contracts transactions. At April 30, 2006 the Fund had no outstanding swap contracts.

M) 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 pooled together with cash collateral for other funds/portfolios advised by Credit Suisse and may be invested in a variety of investments, including certain Credit Suisse-advised funds, funds advised by SSB, the Fund's securities lending agent or money market instruments. 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.

SSB has been engaged by the Fund to act as the Fund's securities lending agent. The Fund's securities lending arrangement provides that the Fund and SSB will share the net income earned from securities lending activities. During the six months ended April 30, 2006, total earnings from the Fund's investment in cash collateral received in connection with securities lending

arrangements was $245,179 of which $229,351 was rebated to borrowers (brokers). The Fund retained $11,281 in income from the cash collateral investment and SSB, as lending agent, was paid $4,547. The Fund may also be entitled to certain minimum amounts of income from its securities lending activities. Securities lending income is accrued as earned.

N) OTHER — 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 affect 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 the Fund invests in junk bonds) the Fund's net asset value.

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 others, currency risks (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 it invests with respect to its 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 gains are earned.

Note 3. Transactions with Affiliates and Related Parties

Credit Suisse serves as investment adviser for the Fund. For its investment advisory services, Credit Suisse is entitled to receive a fee from the Fund at an annual rate of 0.50% of the Fund's average daily net assets. For the six months ended April 30, 2006, investment advisory fees earned and voluntarily waived were $288,012 and $209,588, respectively. Fee waivers and reimbursements are voluntary and may be discontinued by Credit Suisse at any time.

Note 3. Transactions with Affiliates and Related Parties

Credit Suisse Asset Management Securities, Inc. ("CSAMSI"), an affiliate of Credit Suisse, and SSB serve as co-administrators to the Fund. For its co-administrative services, CSAMSI currently receives a fee calculated at an annual rate of 0.10% of the Fund's average daily net assets. For the six months ended April 30, 2006, co-administrative services fees earned by CSAMSI were $57,602.

For its co-administrative services, SSB receives a fee, exclusive of out-of-pocket expenses, calculated in total for all the Credit Suisse funds/portfolios co-administered by SSB and allocated based upon relative average net assets of each fund/portfolio, subject to an annual minimum fee. For the six months ended April 30, 2006, co-administrative services fees earned by SSB (including out-of-pocket expenses) were $52,414.

In addition to serving as the Fund's co-administrator, CSAMSI currently serves as distributor of the Fund's shares. Pursuant to distribution plans adopted by the Fund pursuant to Rule 12b-1 under the 1940 Act, CSAMSI receives fees for its distribution services. Advisor Class shares may pay such fee at an annual rate not to exceed 0.75% of the average daily net assets. This fee is currently calculated at an annual rate of 0.50% of the average daily net assets of the Advisor Class shares. For Class A shares of the Fund, the fee is calculated at an annual rate of 0.25% of the daily average net assets of the Class A shares. For Class B and Class C shares of the Fund, the fees are calculated at an annual rate of 1.00% of the average daily net assets of the Class B and Class C shares of the Fund. Common Class shares do not bear any distribution fees.

Certain brokers, dealers and financial representatives provide transfer agent related services to the Fund, and receive compensation for these services from Credit Suisse. Credit Suisse is then reimbursed by the Fund. For the six months ended April 30, 2006, the Fund reimbursed Credit Suisse $47,635, which is included in the Fund's transfer agent expense.

For the six months ended April 30, 2006, CSAMSI and its affiliates advised the Fund that it retained $644 from commissions earned on the sale of the Fund's Class A shares.

Merrill Corporation ("Merrill"), an affiliate of Credit Suisse, has been engaged by the Fund to provide certain financial printing and fulfillment services. For the six months ended April 30, 2006, Merrill was paid $206 for its services to the Fund.

Note 4. Line of Credit

The Fund, together with other funds/portfolios advised by Credit Suisse (collectively, the "Participating Funds"), participates in a $75 million committed, unsecured line of credit facility ("Credit Facility") for temporary or emergency purposes with Deutsche Bank, A.G. as administrative agent and syndication agent and SSB as operations agent. 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 plus 0.50%. At April 30, 2006, the Fund had no loans outstanding under the Credit Facility. During the six months ended April 30, 2006, the Fund had borrowings under the Credit Facility as follows:

Note 7. Contingencies

In the normal course of business, the Fund may provide general indemnifications pursuant to certain contracts and organizational documents. The Fund's maximum exposure under these arrangements is dependent on future claims that may be made against the Fund and, therefore, cannot be estimated; however, based on experience, the risk of loss from such claims is considered remote.

Credit Suisse Fixed Income Fund

Board Approval of Advisory Agreement (unaudited)

In approving the Investment Advisory Agreement, the Board of Trustees of the Fund, including the Independent Trustees, considered the following factors:

Investment Advisory Fee Rate

The Board reviewed and considered the contractual advisory fee rate of 0.50% for the Fund (the "Contractual Advisory Fee") in light of the extent and quality of the advisory services provided. The Board also reviewed and considered the fee waivers and/ or expense reimbursement arrangements currently in place for the Fund and considered the actual fee rate (after taking waivers and reimbursements into account) of 0.21% for the Fund (the "Net Advisory Fee"). The Board acknowledged that the fee waivers and reimbursements could be discontinued at any time.

Additionally, the Board received and considered information comparing the Fund's Contractual Advisory Fee and Net Advisory Fee and the Fund's overall expenses with those of funds in both the relevant expense group ("Peer Group") and universe of funds (the "Universe") provided by an independent provider of investment company data.

Nature, Extent and Quality of the Services under the Advisory Agreement

The Board received and considered information regarding the nature, extent and quality of services provided to the Fund by Credit Suisse Asset Management, LLC ("Credit Suisse") under the Advisory Agreement. The Board also noted information received at regular meetings throughout the year related to the services rendered by Credit Suisse. The Board reviewed background information about Credit Suisse, including its Form ADV. The Board considered the background and experience of Credit Suisse's senior management and the expertise of, and the amount of attention given to the Fund by senior personnel of Credit Suisse. In addition, the Board reviewed the qualifications, backgrounds and responsibilities of the portfolio management team primarily responsible for the day-to-day portfolio management of the Fund and the extent of the resources devoted to research and analysis of actual and potential investments. The Board also received and considered i nformation about the nature, extent and quality of services and fee rates offered to other Credit Suisse clients for comparable services.

Credit Suisse Fixed Income Fund

Board Approval of Advisory Agreement (unaudited) (continued)

Fund Performance

The Board received and considered the one-, two- three-, four-, five- and ten-year performance of the Fund, along with comparisons, for all presented periods, both to the relevant performance group (the "Performance Group") and universe of funds (the "Performance Universe") for the Fund. The Board was provided with a description of the methodology used to arrive at the funds included in the Performance Group and the Performance Universe.

The Board reviewed information comparing the performance of the various Credit Suisse Funds to performance benchmarks that the Board had previously established and progress that had been made in certain instances toward achieving those benchmarks. The Board also reviewed comparisons between the Fund and its identified benchmark over various time periods.

Credit Suisse Profitability

The Board received and considered a profitability analysis of Credit Suisse based on the fees payable under the Advisory Agreement, including any fee waivers or fee caps, as well as other relationships between the Fund on the one hand and Credit Suisse affiliates on the other. The Board received profitability information for the other funds in the Credit Suisse family of funds.

Economies of Scale

The Board considered whether economies of scale in the provision of services to the Fund were being passed along to the shareholders. Accordingly, the Board considered whether alternative fee structures (such as breakpoint fee structures) would be more appropriate or reasonable taking into consideration economies of scale or other efficiencies that might accrue from increases in the Fund's asset levels.

Other Benefits to Credit Suisse

The Board considered other benefits received by Credit Suisse and its affiliates as a result of its relationship with the Fund. Such benefits include, among others, research arrangements with brokers who execute transactions on behalf of the Fund, administrative and brokerage relationships with affiliates of Credit Suisse and benefits potentially derived from an increase in Credit Suisse's businesses as a result of its relationship with the Fund (such as the ability to market to shareholders other financial products offered by Credit Suisse and its affiliates).

Credit Suisse Fixed Income Fund

Board Approval of Advisory Agreement (unaudited) (continued)

The Board considered the standards applied in seeking best execution and the existence of quality controls applicable to brokerage allocation procedures. The Board also reviewed Credit Suisse's method for allocating portfolio investment opportunities between the Fund and other advisory clients.

Conclusions

In selecting Credit Suisse, and approving the Advisory Agreement and the investment advisory fee under such agreement, the Board concluded that:

• although the Contractual Advisory Fee was higher than the median of its Peer Group, the fee was considered reasonable recognizing that the amount that shareholders were actually charged, the Net Advisory Fee, was approximately at the median of the Fund's Peer Group.

• the Fund's one-, two- and three-year performance was above the median of its Performance Group and Performance Universe, and while the Fund's four-, five- and ten-year performance record was below the median of its Performance Group and Performance Universe, the improvements in the Fund's recent performance were a positive reflection of the enhanced research and portfolio management changes instituted by Credit Suisse.

• the Board was satisfied with the nature and extent of the investment advisory services provided to the Fund by Credit Suisse and that, based on dialogue with management and counsel, the services provided by Credit Suisse under the Advisory Agreement are typical of, and consistent with, those provided to mutual funds by other investment advisers.

• in light of the costs of providing investment management and other services to the Fund and Credit Suisse's ongoing commitment to the Fund and willingness to cap fees and expenses, the profits and other ancillary benefits that Credit Suisse and its affiliates received were considered reasonable.

• Credit Suisse's profitability based on fees payable under the Advisory Agreement was reasonable in light of the nature, extent and quality of the services provided to the Fund thereunder.

• in light of the relatively small size of the Fund and the amount of the Net Advisory Fees, the Fund's current fee structure (without breakpoints) was considered reasonable.

No single factor reviewed by the Board was identified by the Board as the principal factor in determining whether to approve the Advisory Agreement. The Independent Trustees were advised by separate independent legal counsel throughout the process.
