Dear Shareholder:

Performance Summary

11/01/05 – 04/30/06

Fund & Benchmarks	Performance
Total Return (based on NAV)¹		7.74	%
Total Return (based on market value)¹		(7.61	)%
Merrill Lynch US High Yield Master II Constrained Index²		5.01	%
Citigroup High-Yield Market Index²		4.56	%

Market Overview

The high yield market has experienced six consecutive months of positive returns, generating returns of 5.01% for the semi-annual period ending April 30, 2006 (according to the Merrill Lynch US High Yield Master II Constrained benchmark). Low-rated securities outperformed the broader market with returns of 9.98% while the more interest rate sensitive BB-rated securities underperformed, returning 3.10%. For the time period, average spreads tightened 68 basis points to 303 versus treasuries.

All sectors within the benchmark posted positive returns for the period with Airlines, Theaters, and Building Materials leading the way. Auto performance was volatile. The sector was the largest detractor from market performance for February 2006 and November 2005, but the largest contributor to performance in January 2006 and March 2006. Sectors that underperformed the index include Utilities and Energy.

Credit fundamentals continue to be supportive of the high yield market. Moody's default rate remains low, drifting from 1.96% in November 2005 to 1.65% for the month of April 2006. In addition, the high yield distressed ratio, a leading indicator for future default rates, remains low at 2.8% for April 2006. The technical environment remains constructive as well. The new issue calendar has remained light for most of the period, and even though it has picked up with several large deals more recently, market technicals remain firm as cash from coupon and bond redemptions has outpaced supply.

Strategic Review

The Fund outperformed in the period, benefiting from an underweight to the more interest rate sensitive BB-rated securities. The Fund's overweight to higher yielding securities also provided positive contribution to return.

Superior security selection, coupled with an overweight in the Buildings Materials, Electronics, Packaging, as well as Support-Services sectors, provided the greatest positive contribution to the Fund's relative performance in the period. Positive security selection in the Gaming, Steel, Telecom-Wireless and Utility sectors also added to relative returns. Security selection in the Autos sector detracted from returns.

Benchmark Review

Structural changes within the high yield universe have necessitated an evaluation of our benchmark. Specifically, the downgrades of General Motors Corp. and Ford Motor Company have created high issuer concentrations in the traditional high yield indices. After extensively studying the various benchmarks available, the fund will switch its reference index to the Merrill Lynch US High Yield Master II Constrained Index. This index caps issuer weights to a maximum of 2% and therefore addresses current and future concentration issues.

Outlook and Strategy

We remain cautiously optimistic for high yield returns for the remainder of 2006. Robust economic growth, low defaults, and a below average distressed ratio provide the backdrop for a favorable fundamental outlook in our view. In addition, the new issue calendar has remained light, leading to a strong technical demand. Though yield spreads are still near historic lows, we believe the market conditions support current levels and believe that they could remain range-bound going forward. With yields hovering in the 8% area, coupon income generation alone could potentially provide more than respectable total returns. Strategically, we will look to use the market's strength as an opportunity to exit some less liquid, deteriorating credits.

We appreciate your interest in the Fund and would be pleased to respond to your questions or comments. Any questions regarding net asset value, performance, dividends, portfolio management or allocations should be directed to Credit Suisse Asset Management, LLC at (800) 293-1232. All other inquiries regarding account information, requests for the latest financial information or other reports should be directed to the Fund's Shareholder Servicing Agent at (800) 730-6001.

High yield bonds are lower-quality bonds that are also known as "junk bonds." Such bonds entail greater risks than those found in higher-rated securities.

In addition to historical information, this report contains forward-looking statements, which may concern, among other things, domestic and foreign markets, industry and economic trends and developments and government regulation and their potential impact on the Fund's investment portfolio. 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.

We wish to remind shareholders whose shares are registered in their own name that they automatically participate in the Fund's dividend reinvestment program known as the Investlink^SM Program (the "Program"). The Program can be of value to shareholders in maintaining their proportional ownership interest in the Fund in an easy and convenient way. A shareholder whose shares are held in the name of a broker/dealer or nominee should contact the Fund's Transfer Agent for details about participating in the Program.

² Merrill Lynch US High Yield Master II Constrained Index is an unmanaged index that tracks the performance of below investment-grade U.S. dollar-denominated corporate bonds issued in the U.S. domestic market, where each issuer's allocation is limited to 2% of the index. Investors cannot invest directly in an index. In order to ensure that the index the Fund is benchmarked against is best aligned with the Fund's emphasis on diversification and risk management, effective February 28, 2006, this index replaces the Citigroup High Yield Market Index, a broad-based, unmanaged index of high-yield securities that is compiled by Citigroup Global Markets Inc.

Credit Suisse High Yield Bond Fund

Notes to Financial Statements

April 30, 2006 (unaudited)

Note 1. Organization

Credit Suisse High Yield Bond Fund (the "Fund") is a business trust organized under the laws of the State of Delaware on April 30, 1998. The Fund is registered with the Securities and Exchange Commission under the Investment Company Act of 1940, as amended ("Investment Company Act"), as a non-diversified, closed-end management investment company. The Fund's primary objective is to seek high current income.

The following is a summary of significant accounting policies consistently followed by the Fund in its operations and in connection with the preparation of its financial statements.

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 ("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. 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 direction of, the Board of Trustees under procedures established by the Board of Trustees.

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. The cost of investments sold is determined by use of the specific identification method for both financial reporting and income tax purposes. Accretion of discount and amortization of premium is recognized using the effective interest method.

D) DIVIDENDS AND DISTRIBUTIONS TO SHAREHOLDERS — The Fund declares and pays dividends on a monthly basis. Capital gains, if any, net of capital losses, are distributed annually. Income dividends and capital gain distributions are determined in accordance with income tax regulations, which may differ from accounting principles generally accepted in the United States of America ("GAAP"). These differences are primarily due to

Credit Suisse High Yield Bond Fund

Notes to Financial Statements (continued)

April 30, 2006 (unaudited)

differing treatments of income and gains on various investment securities held by the Fund, timing differences and differing characterization of distributions made by the Fund.

The Fund's dividend policy is to distribute substantially all of its net investment income to its shareholders on a monthly basis. However, in order to provide shareholders with a more consistent yield to the current trading price of shares of beneficial interest of the Fund, the Fund may at times pay out less than the entire amount of net investment income earned in any particular month and may at times in any month pay out such accumulated but undistributed income in addition to net investment income earned in that month. As a result, the dividends paid by the Fund for any particular month may be more or less than the amount of net investment income earned by the Fund during such month.

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) CASH FLOW INFORMATION — Cash, as used in the Statement of Cash Flows, is the amount reported in the Statement of Assets and Liabilities. The Fund invests in securities and distributes dividends from net investment income and net realized gains, if any (which are either paid in cash or reinvested at the discretion of shareholders). These activities are reported in the Statement of Changes in Net Assets. Information on cash payments is presented in the Statement of Cash Flows. Accounting practices that do not affect reporting activities on a cash basis include unrealized gain or loss on investment securities and accretion or amortization income recognized on investment securities.

G) 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 income and expenses during the reporting period. Actual results could differ from those estimates.

H) SECURITIES LENDING — Loans of securities are required at all times to be secured by collateral at least equal to 100% of the market value of domestic securities on loan (including any accrued interest thereon). Cash collateral received by the Fund in connection with securities lending activity is reinvested into either fully collateralized repurchase agreements with Bear, Stearns & Co., Inc. (an affiliate of the custodian, Custodial Trust Company, and the borrower, Bear, Stearns Securities Corp. (the "Borrower")), registered money market mutual funds (subject to regulatory limitations) or some combination thereof. In the event of default or bankruptcy by the Borrower or its affiliates to the agreement, realization and/or retention of the Fund's collateral may be subject to legal proceedings.

The Fund's securities lending arrangement provides that the Fund and the Borrower will share the net income earned from the 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 the securities lending arrangement was $1,505,489 of which $1,175,111 was rebated to the Borrower. The Fund retained $330,378 in income from the cash collateral investment. The Fund is entitled to a certain minimum amount of income from its securities lending activities. Securities lending income is accrued as earned.

Note 3. Transactions with Affiliates and Related Parties

The Fund has entered into an Investment Advisory Agreement (the "Advisory Agreement") with Credit Suisse Asset Management, LLC ("Credit Suisse"). The Advisory Agreement provides for a fee at the annual rate of 1.00% of the first $250 million of the average weekly value of the Fund's total assets minus the sum of liabilities (other than aggregate indebtedness constituting leverage) and 0.75% of the average weekly value of the Fund's total assets minus the sum of liabilities (other than aggregate indebtedness constituting leverage) greater than $250 million. For the six months ended April 30, 2006, investment advisory fees earned were $1,560,436.

State Street Bank and Trust Company ("SSB") serves as Accounting and Administrative Agent for the Fund. For its 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, administrative services fees earned by SSB (including out-of-pocket expenses) were $102,577.

The Independent Trustees receive fifty percent (50%) of their annual retainer in the form of shares purchased by the Fund's transfer agent in the open market.

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 $1,037 for its services to the Fund.

Note 4. Line of Credit

The Fund has a $150 million line of credit provided by Citibank North America, Inc., under a Revolving Credit and Security Agreement (the "Agreement") dated April 12, 2002, as amended from time to time, primarily to leverage its investment portfolio. Under this Agreement, the Fund may borrow the lesser of $150 million or 33¹/₃% of its gross assets. Interest is payable at the Bank's Base Rate plus a commission of 0.05%. The Fund pays a program fee of 0.20% of the average daily amount leveraged, an administration fee of 0.02% of the average daily amount leveraged and a liquidity fee of 0.15% of the maximum borrowing limit (currently $150 million). The Agreement requires, among other provisions, that the percentage obtained by dividing total indebtedness for money borrowed by total assets of the Fund shall not exceed 33¹/₃%. At April 30, 2006 the Fund had loans outstanding under the Agreement of $110,000,000. During the six months ended April 30, 2006, the Fund had borrowings under the Agreement as follows:

Average Daily Loan Balance				Weighted Average Interest Rate				Maximum Daily Loan Outstanding
$	108,362,637				4.448	%		$	110,000,000

Note 5. Purchases and Sales of Securities

For the six months ended April 30, 2006, purchases and sales of investment securities (excluding short-term investments) were $127,987,055 and $93,748,632, respectively.

At April 30, 2006, the identified cost for federal income tax purposes, as well as 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 the net unrealized depreciation from investments were $398,269,223, $9,969,401, $(13,009,187) and $(3,039,786), respectively.

Note 6. Fund Shares

The Fund has one class of shares of beneficial interest, par value $0.001 per share; an unlimited number of shares are authorized. Transactions in shares of beneficial interest were as follows:

				For the Six Months Ended April 30, 2006 (unaudited)				For the Year Ended October 31, 2005
Shares issued through reinvestment of dividends					370,982				861,846

Note 7. Concentration of Risk

The Fund invests in securities offering high current income, which generally will be in the lower rating categories of recognized ratings agencies (commonly known as "junk bonds").

These securities generally involve more credit risk than securities in the higher rating categories. In addition, the trading market for high yield securities may be relatively less liquid than the market for higher-rated securities. The Fund's use of leverage also increases exposure to capital risk.

Note 8. 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.

DIVIDEND REINVESTMENT PLAN

Referenced below are policies related to the Fund's Automatic Dividend Reinvestment Plan (the "Plan"). These policies apply to shareholders whose shares are registered directly with the Fund in their own name. Shareholders whose shares are purchased through a broker-dealer or nominee should contact such broker-dealer or nominee regarding questions related to the reinvestment of the Fund's dividends.

Pursuant to the Fund's Plan, unless a shareholder otherwise elects, all dividends and capital gain distributions will be automatically reinvested by Computershare as agent for Shareholders in administering the Plan (the "Plan Agent"), in additional shares of the Fund. Shareholders who elect not to participate in the Plan will receive all dividends and other distributions in cash paid by check mailed directly to the shareholder of record (or, if the shares are held in street or other nominee name, then to such nominee) by Computershare as the Dividend Disbursing Agent. Such participants may elect not to participate in the Plan and to receive all dividends and capital gain distributions in cash by sending written instructions to Computershare as the Dividend Disbursing Agent, at the address set forth below. Participation in the Plan is completely voluntary and may be terminated or resumed at any time without penalty by written notice if received by the Plan Agent not less than ten days prior to any dividend record date; otherwise such termination will be effective with respect to any subsequently declared dividend or other distribution.

Whenever the Fund declares an income dividend or a capital gain distribution (collectively referred to as "dividends") payable either in shares or in cash, non-participants in the Plan will receive cash and participants in the Plan will receive the equivalent in shares. The shares will be acquired by the Plan Agent for the participants' accounts, depending upon the circumstances described below, either (i) through receipt of additional unissued but authorized shares from the Fund ("newly issued shares") or (ii) by purchase of outstanding shares on the open market ("open-market purchases") on the AMEX or elsewhere. If on the record date for the dividend, the net asset value per share is equal to or less than the market price per share plus estimated brokerage commissions (such condition being referred to herein as "market premium"), the Plan Agent will invest the dividend amount in newly issued shares on behalf of the participants. The number of newly issued shares to be credited to each participant's account will be determined by dividing the dollar amount of the dividend by the net asset value per share on the date the shares are issued. If on the dividend record date the net asset value per share is greater than the market value (such condition being referred to herein as "market-discount"), the Plan Agent will invest the dividend amount in shares acquired on behalf of the participants in open-market purchases.

In the event of a market discount on the dividend record date, the Plan Agent will have until the last business day before the next date on which the shares trade on an "ex-dividend" basis or in no event more than 30 days after the dividend record date (the "last purchase date") to invest the dividend amount in shares acquired in open-market purchases. It is contemplated that the Fund will pay monthly income dividends. Therefore, the period during which open-market purchases can be made will exist only from the record date of the dividend through the date before the next "ex-dividend" date. If, before the Plan Agent has completed its open-market purchases, the market price of a share exceeds the net asset value per share, the average per share purchase price paid by the Plan Agent may exceed the net asset value of the shares, resulting in the acquisition of fewer shares than if the dividend had been paid in newly issued shares on the dividend record date. Because of the foregoing difficulty with respect to open market purchases, the Plan provides that if the Plan Agent is unable to invest the full dividend amount in open market purchases during the purchase period or if the market discount shifts to a market premium during the purchase period, the Plan Agent may cease making open-market purchases and may invest the uninvested portion of the dividend amount in newly issued shares at the net

asset value per share at the close of business on the last purchase date.

The Plan Agent maintains all shareholders' accounts in the Plan and furnishes written confirmation of all transactions in the accounts, including information needed by shareholders for tax records. Shares in the account of each Plan participant will be held by the Plan Agent on behalf of the Plan participant, and each shareholder proxy will include those shares purchased or received pursuant to the Plan. The Plan Agent will forward all proxy solicitation materials to participants and vote proxies for shares held pursuant to the Plan in accordance with the instructions of the participants. In the case of shareholders such as banks, brokers or nominees that hold shares for others who are the beneficial owners, the Plan Agent will administer the Plan on the basis of the number of shares certified from time to time by the record shareholder and held for the account of beneficial owners who participate in the Plan.

There will be no brokerage charges with respect to shares issued directly by the Fund as a result of dividends or capital gains distributions payable either in shares or in cash. However, each participant will pay a pro rata share of brokerage commissions incurred with respect to the Plan Agent's open-market purchases in connection with the reinvestment of dividends.

The automatic reinvestment of dividends will not relieve participants of any Federal, state or local income tax that may be payable (or required to be withheld) on such dividends.

Shareholders participating in the Plan may receive benefits not available to shareholders not participating in the Plan. If the market price (plus commissions) of the shares is above their net asset value, participants in the Plan will receive shares of the Fund at less than they could otherwise purchase them and will have shares with a cash value greater than the value of any cash distribution they would have received on their shares. If the market price plus commissions is below the net asset value, participants will receive distributions in shares with a net asset value greater than the value of any cash distribution they would have received on their shares. However, there may be insufficient shares available in the market to make distributions in shares at prices below the net asset value. Also, since the Fund does not redeem shares, the price on resale may be more or less than the net asset value.

Experience under the Plan may indicate that changes are desirable. Accordingly, the Fund reserves the right to amend or terminate the Plan. There is no direct service charge to participants in the Plan; however, the Fund reserves the right to amend the Plan to include a service charge payable by the participants.

All correspondence concerning the Plan should be directed to the Plan Agent at P.O. Box 43010, Providence, RI 02940-3010, or call the plan agent at 1-800-730-6001.

LEVERAGE — BENEFITS AND RISKS

The use of leverage by the Fund creates an opportunity for increased net income and capital appreciation for the Fund, but, at the same time, creates special risks, and there can be no assurance that a leveraging strategy will be successful during any period in which it is employed. The Fund intends to utilize leverage to provide the Shareholders with a potentially higher return. Leverage creates risks for Shareholders including the likelihood of greater volatility of net asset value and market price of the Fund's shares and the risk that fluctuations in interest rates on borrowings and short-term debt may affect the return to Shareholders. To the extent the income or capital appreciation derived from securities purchased with funds received from leverage exceeds the cost of leverage, the Fund's return will be greater than if leverage had not been used. Conversely, if the income or capital appreciation from the securities purchased with such funds is not sufficient to cover the cost of leverage, the return to the Fund will be less than if leverage had not been used, and therefore the amount available for distribution to Shareholders as dividends and other distributions will be reduced. In the latter case, Credit Suisse in its best judgment nevertheless may determine to maintain the Fund's leveraged position if it deems such action to be appropriate under

Credit Suisse High Yield Bond Fund

Additional Information (unaudited) (continued)

the circumstances. During periods in which the Fund is utilizing leverage, the Management Fee will be higher than if the Fund did not utilize a leveraged capital structure because the fee is calculated as a percentage of the Managed Assets including those purchased with leverage. Certain types of borrowings by the Fund may result in the Fund's being subject to covenants in credit agreements, including those relating to asset coverage and portfolio composition requirements. The Fund's lenders may establish guidelines for borrowing which may impose asset coverage or portfolio composition requirements that are more stringent than those imposed by the Investment Company Act. It is not anticipated that these covenants or guidelines will impede Credit Suisse in managing the Fund's portfolio in accordance with the Fund's investment objectives and policies.

Credit Suisse High Yield Bond Fund

Board Consideration and Re-Approval of Investment Advisory Agreement (unaudited)

Section 15(c) of the Investment Company Act of 1940 (the "1940 Act") contemplates that the Board of Trustees (the "Board") of Credit Suisse High Yield Bond Fund (the "Fund"), including a majority of the Trustees who have no direct or indirect interest in the investment advisory agreement and are not "interested persons" of the Fund, as defined in the 1940 Act (the "Independent Trustees"), will annually review and re-approve the terms of the Fund's existing investment advisory agreement. In this regard, the Board reviewed and re-approved, during the six months covered by this report an investment advisory agreement (the "Advisory Agreement") with Credit Suisse Asset Management, LLC ("Credit Suisse") for the Fund.

More specifically, at a meeting held on November 16-17, 2005, the Board, including the Independent Trustees advised by their independent legal counsel, considered the factors and reached the conclusions described below relating to the selection of Credit Suisse and the re-approval of the Advisory Agreement.

Nature, Extent and Quality of Services

The Board received and considered various data and information regarding the nature, extent and quality of services provided to the Fund by Credit Suisse under the Advisory Agreement. The most recent investment adviser registration form ("Form ADV") for Credit Suisse was provided to the Board, as were responses of Credit Suisse to requests submitted by the Independent Trustees' independent legal counsel on behalf of such Trustees. The Board reviewed and analyzed these materials, which included, among other things, information about the background and experience of the senior management and the expertise of, and amount of attention devoted to the Fund by investment personnel of Credit Suisse. In this regard, the Board specifically reviewed the qualifications, background and responsibilities of the chief investment officer who is primarily responsible for day-to-day portfolio management services for the Fund.

In addition, the Board received and reviewed information on Securities and Exchange Commission ("SEC") and other regulatory inquiries and examinations relating to the Fund and Credit Suisse. The Board considered the investment and legal compliance programs of the Fund and Credit Suisse, including their implementation of enhanced compliance policies and procedures in response to SEC rule changes and other regulatory initiatives. The Board also considered the Fund's Chief Compliance Officer's report and recommendations.

The Board evaluated the ability of Credit Suisse, based on its resources, reputation and other attributes, to attract and retain highly qualified investment professionals, including research, advisory, and supervisory personnel. In this connection, the Board considered information regarding Credit Suisse's compensation arrangements for its personnel involved in the management of the Fund.

Based on the above factors, together with those referenced below, the Board concluded that it was generally satisfied with the nature, extent and quality of the investment advisory services provided to the Fund by Credit Suisse.

Fund Performance and Expenses

The Board considered performance results for the Fund over a number of years, as well as for recent periods. It also considered these results in comparison to the group of funds consisting of all closed-end leveraged high current yield funds (the "Performance Universe"), as well as to the Fund's benchmark indices, the Lipper Closed-End Leveraged High Yield Bond Funds Index and the Citigroup High Yield Market Index. Lipper Inc. ("Lipper"), an independent provider of investment company data, determined the Performance Universe for the Fund and provided the comparative data. The Board was provided with a description of the methodology used by Lipper to select the closed-end mutual funds in the Fund's Performance Universe. The Board noted that, although the Fund had underperformed the median performance of the funds in its Performance Universe in some periods, it had out- performed the median performance in other periods.

Credit Suisse High Yield Bond Fund

Board Consideration and Re-Approval of Investment Advisory Agreement (unaudited) (continued)

The Board received and considered statistical information regarding the Fund's total expense ratio and its various components, including management fees, non-management fees and actual total expenses of the Fund (including and excluding investment-related expenses and taxes). It also considered comparisons of these fees to the expense information of the group of funds that was determined to be the most similar to the Fund (the "Peer Group") and to the median expenses of a broader universe of relevant funds (the "Expense Universe"), which comparative data was provided by Lipper. The Board was provided with a description of the methodology used by Lipper to select the closed-end mutual funds in the Fund's Peer Group and Expense Universe.

The Board noted that the management fee paid by the Fund is appreciably higher that the median management fee of the Fund's Peer Group. However, the Board considered that the overall expense ratio of the Fund is consistent with the median expense ratio of the Fund's Peer Group, both including and excluding investment-related expenses and taxes.

Based on the above-referenced considerations and other factors, the Board concluded that the overall performance and expense results supported the re-approval of the Advisory Agreement for the Fund.

Investment Advisory Fee Rate

The Board reviewed and considered the proposed contractual investment advisory fee rate (the "Advisory Agreement Rate") payable by the Fund to Credit Suisse for investment advisory services.

Additionally, the Board received and considered information comparing the Advisory Agreement Rate (both on a stand-alone basis and on a combined basis with the Fund's administration fee rate) with those of the other funds in its Peer Group. The Board noted that the Fund's administrator is not affiliated with Credit Suisse and that the Fund's administration agreement and corresponding fees were negotiated at arm's-length. In this regard, the Board observed that the Advisory Agreement Rate was appreciably higher than the median rate of funds in its Peer Group. However, the Board considered that the Fund's non-management expenses were significantly lower than the median rate of the Peer Group. The Board concluded that these factors supported the Advisory Agreement Rate.

Profitability

The Board received and considered an estimated profitability analysis of Credit Suisse based on the Advisory Agreement Rate, as well as on any other relationships between the Fund and Credit Suisse and its affiliates. The Board concluded that, in light of the costs of providing investment management and other services to the Fund, the profits and other ancillary benefits that Credit Suisse and its affiliates received with regard to providing these services to the Fund were not unreasonable.

Economies of Scale

The Board received and considered information regarding whether there have been economies of scale with respect to the management of the Fund, whether the Fund has appropriately benefited from any economies of scale, and whether there is potential for realization of any further economies of scale. The Board concluded that any actual or potential economies of scale are, or will be, shared fairly with Fund shareholders, including most particularly through Advisory Agreement Rate breakpoints.

The Board observed that the Advisory Agreement did not initially offer breakpoints. However, the Board noted that as part of its past review and re-approval of the Advisory Agreements it had approved the inclusion of breakpoints in the Advisory Agreement Rate and, as a result, there would be potential for realizing economies of scale.

Information about Services to Other Clients

The Board also received and considered information about the nature and extent of services and fee rates offered by Credit Suisse to its other clients, including other registered investment companies and institutional investors and investment companies to which Credit Suisse serves as an unaffiliated sub-adviser. The Board concluded that the Advisory Agreement Rate was reasonable given the nature and extent of services provided and comparison with fee rates offered to other clients. Where rates offered to other clients were appreciably lower, the Board concluded, based on information provided by Credit Suisse, that the costs associated with managing and operating a registered, closed-end, high yield bond fund, compared with other clients and other funds, provided a justification for the higher fee rates charged to the Fund.

Other Factors and Broader Review

As discussed above, the Board reviews detailed materials received from Credit Suisse annually as part of the re-approval process under Section 15(c) of the 1940 Act. The Board also reviews and assesses the quality of the services that the Fund receives throughout the year. In this regard, the Board reviews reports of Credit Suisse at least in each of its quarterly meetings, which include, among other things, a detailed portfolio review, and detailed fund performance reports, and confers with the chief investment officer of the Fund at various times throughout the year.

After considering the above-described factors and based on its deliberations and its evaluation of the information provided to it, the Board concluded that re-approval of the Advisory Agreement for the Fund was in the best interest of the Fund and its remaining shareholders. Accordingly, the Board unanimously re-approved the Advisory Agreement.
