Semiannual Investment Adviser's Report

April 30, 2009 (unaudited)

June 9, 2009

Dear Shareholder:

Performance Summary

11/1/08 – 04/30/09

Fund & Benchmark	Performance
Total Return (based on NAV)1		6.90	%
Total Return (based on market value)1		2.32	%
Merrill Lynch US High Yield Master II Constrained Index2		15.71	%

Market Review: A volatile, yet ultimately positive period

For the six-month period ending April 30, 2009, volatile conditions persisted in the credit markets. The high yield market experienced significant sell-offs from September through mid-December 2008, as financial market weakness deepened and losses were experienced across the board — from equities to bonds.

By mid-December, spreads on the Merrill Lynch US High Yield Master II Constrained Index, the Fund's benchmark, reached all-time wide levels of +2131 basis points versus the Treasury market. In the second half of the month, however, a series of government actions to support the financial markets and stimulate the broader economy resulted in a reversal in credit market momentum. This more positive sentiment was reinforced in March as (i) high yield mutual funds experienced inflows, (ii) additional information was provided regarding the U.S. government's stimulus plans, and (iii) several U.S. banks announced improvement in their first quarter earnings trends. This turnaround resulted in a gain of 25.8% for the Merrill Lynch US High Yield Master II Constrained Index from December 2008 to April 2009, and returns of 15.71% for the full semiannual period. Overall, spreads tightened 234 basis points versus Treasury bonds, ending the period at +1333 basis points.

BB-rated securities outperformed during the period, while CCC-rated securities performed in line with the Index and B-rated securities underperformed.

Default rates, as reported by Moody's Investor Services, rose from 3.0% in October 2008 to 8.3% in April 2009. The Merrill Lynch distress ratio (defined as the proportion of bonds trading over 1,000 bps — and a leading indicator of future defaults) ended the period at 57.2%, down from its recent high of 83.6% in November 2008.

Strategic Review and Outlook: Expecting continued volatility as fundamentals remain under pressure

For the six-month period ended April 30, 2009, the Fund underperformed the benchmark. While superior security selection in auto loans and media-cable contributed to performance, an underweight to finance and holdings in chemicals, gaming, electronics and media-broadcast hurt relative returns. In addition, an overweight to B-rated securities detracted from relative performance. Lastly, in the fourth quarter of 2008, the Fund was forced to decrease its' leverage as the decline in high yield bond market values caused the value of the Fund's assets to decline below a threshold contained in the Fund's financing facility, which also detracted from returns.

Given the deteriorating fundamental backdrop, portfolio management strategy has remained selective and we continue to opportunistically pare back exposures in riskier names. We have maintained core holdings in the more defensive industries and emphasized the high yield quality issues. In addition, we remain relatively constructive on several issuers in the cable and telecommunications space. In contrast, we remain cautious with respect to consumer-driven and more cyclical industries and have sought to limit exposures to these sectors.

Credit Suisse High Yield Bond Fund

Semiannual Investment Adviser's Report (continued)

April 30, 2009 (unaudited)

Market conditions continue to be characterized by unprecedented volatility. In addition, recent performance numbers have highlighted the fact that high yield market valuations had reached extreme levels in the fourth quarter of 2008 — indicating default expectations of more than 20%. However, credit conditions remain tight and recent economic indicators have continued to weaken, which points to a severe global recession. While we believe recent policy initiatives should ultimately stabilize the financial markets as well as the broader global economy, we expect conditions to stay volatile as liquidity remains limited and balance sheet repair continues.

Martha Metcalf Chief Investment Officer*	George Hornig Chief Exective Officer and President**

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.

Average Annual Returns

April 30, 2009 (unaudited)

	1 Year			3 Years			5 Years			10 Years
Net Asset Value (NAV)		(34.58	)%		(11.40	)%		(3.45	)%		(1.38	)%
Market Value		(39.32	)%		(13.78	)%		(6.38	)%		(3.32	)%

Credit Suisse currently waives fees and/or reimburses expenses, without which performance would be lower. Waivers and/or reimbursements are subject to change and may be discontinued at any time. Returns represent past performance. Total investment return at net asset value is based on changes in the net asset value of fund shares and assumes reinvestment of dividends and distributions, if any. Total investment return at market value is based on changes in the market price at which the fund's shares traded on the stock exchange during the period and assumes reinvestment of dividends and distributions, if any, at actual prices pursuant to the fund's dividend reinvestment program. Because the fund's shares trade in the stock market based on investor demand, the fund may trade at a price higher or lower than its NAV. Therefore, returns are calculated based on share price and NAV. Past performance is no guarantee of future results. The current performance of the fund may be lower or higher than the figures shown. The fund's yield, return and market price and NAV will fluctuate. Performance information current to the most recent month-end is available by calling 1-800-293-1232.

Credit Suisse High Yield Bond Fund

Notes to Financial Statements

April 30, 2009 (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.

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. 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 "Valuation Time"). If no sales are reported, equ ity 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. At April 30, 2009, the Fund held 0.05% of its net assets in securities valued at fair value as determined in good faith under procedures established by the Board of Trustees with an aggregate cost of $3,840,600 and fair value of $60,817. The Fund's estimate of fair value assumes a willing buyer and a willing seller neither acting un der the compulsion to buy or sell. Although these securities may be resold in privately negotiated transactions, the prices realized on such sales could differ from the prices originally paid by the Fund or the current carrying values, and the difference could be material.

The Fund adopted Financial Accounting Standards Board Statement of Financial Accounting Standards No. 157, Fair Value Measurements ("FAS 157"), effective November 1, 2008. In accordance with FAS 157, fair value is defined as the price that the Fund would receive upon selling an investment in a timely transaction to an independent buyer in the principal or most advantageous market of the investment. FAS 157 established a three-tier hierarchy to maximize the use of observable market data and minimize the use of unobservable inputs and to establish classification of fair value measurements for disclosure purposes. Inputs refer broadly to the assumptions that market participants would use in pricing the asset or liability, including assumptions about risk, for example, the risk inherent in a particular valuation technique used to measure fair value including such a pricing model and/or the risk inherent in the inputs to the valuation technique. Inputs may be observable or unobservable. Observable inputs are inputs that reflect the assumptions market participants would use in pricing the asset or liability developed based on market data obtained from sources independent of the reporting entity. Unobservable inputs are inputs that reflect the reporting entity's own assumptions about the assumptions market participants

20

Credit Suisse High Yield Bond Fund

Notes to Financial Statements (continued)

April 30, 2009 (unaudited)

would use in pricing the asset or liability developed based on the best information available in the circumstances. The three-tier hierarchy of inputs is summarized in the three broad Levels listed below.

• Level 1 — quoted prices in active markets for identical investments

• Level 2 — other significant observable inputs (including quoted prices for similar investments, interest rates, prepayment speeds, credit risk, etc.)

• Level 3 — significant unobservable inputs (including the Fund's own assumptions in determining the fair value of investments)

The inputs or methodology used for valuing securities are not necessarily an indication of the risk associated with investing in those securities.

The following is a summary of the inputs used as of April 30, 2009 in valuing the Fund's investments carried at value:

Valuation Inputs	Investments in Securities		Other Financial Instruments*
Level 1 — Quoted Prices	$	168,156	$	19,338
Level 2 — Other Significant Observable Inputs		137,054,722		—
Level 3 — Significant Unobservable Inputs		60,817		—
Total	$	137,283,695	$	19,338

*  Other financial instruments include futures, forwards and swap contracts.

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 premiums and accretes discounts using the effective interest method. 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.

D) DIVIDENDS AND DISTRIBUTIONS TO SHAREHOLDERS — The Fund declares and pays dividends on a monthly basis. 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 carryforward, 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").

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

21

Credit Suisse High Yield Bond Fund

Notes to Financial Statements (continued)

April 30, 2009 (unaudited)

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.

During June 2006, the Financial Accounting Standards Board ("FASB") issued FASB Interpretation 48 ("FIN 48" or the "Interpretation"), Accounting for Uncertainty in Income Taxes — an interpretation of FASB statement 109. The Fund has reviewed its current tax positions and has determined that no provision for income tax is required in the Fund's financial statements. The Fund's federal tax returns for the prior three fiscal years remain subject to examination by the Internal Revenue Service.

F) SHORT-TERM INVESTMENTS — The Fund, together with other funds/portfolios advised by Credit Suisse Asset Management, LLC ("Credit Suisse"), an indirect, wholly-owned subsidiary of Credit Suisse Group AG, 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.

G) 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.

H) 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 these estimates.

I) 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, 2009, total earnings from the Fund's investment in cash collateral received

22

Notes to Financial Statements (continued)

April 30, 2009 (unaudited)

in connection with securities lending arrangements was $1,584, of which $529 was rebated to borrowers (brokers). The Fund retained $844 in income from the cash collateral investment, and SSB, as lending agent, was paid $211. The Fund may also be entitled to certain minimum amounts of income from its securities lending activities. Securities lending income is accrued as earned.

J) 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 forward 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, 2009, the Fund had the following open forward foreign currency contracts:

Forward Foreign Currency to be Purchased (Local)		Forward Foreign Currency to be Sold (Local)		Expiration Date	Value on Settlement Date			Current Value			Unrealized Appreciation
USD	2,250,789	EUR	1,685,000	07/16/09	$	(2,250,789	)	$	(2,232,131	)	$	18,658
USD	667,490	GBP	450,000	07/16/09		(667,490	)		(666,810	)		680
Total											$	19,338

Currency Abbreviations:

EUR — Euro Currency

GBP — British Pound

USD — United States Dollar

K) CREDIT DEFAULT SWAPS — The Fund may enter into credit default swap agreements either as a buyer or seller. The Fund may buy a credit default swap to attempt to mitigate the risk of default or credit quality deterioration in one or more individual holdings or in a segment of the fixed income securities market. The Fund may sell a credit default swap in an attempt to gain exposure to an underlying issuer's credit quality characteristics without investing directly in that issuer.

The Fund bears the risk of loss of the amount expected to be received under a credit default swap agreement in the event of the default or bankruptcy of the counterparty. The Fund will enter into swap agreements only with counterparties that meet certain standards of creditworthiness (generally, such counterparties would have to be eligible counterparties under the terms of the Fund's repurchase agreement guidelines). Credit default swap agreements are generally valued at a price at which the counterparty to such agreement would terminate the agreement. At April 30, 2009, the Fund had no outstanding credit default swap contracts.

Note 3. Transactions with Affiliates and Related Parties

The Fund has entered into an Investment Advisory Agreement (the "Advisory Agreement") with 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. Effective January 1, 2007, Credit Suisse agreed to waive 0.15% of the fees payable under the Advisory Agreement. For the six months ended April 30, 2009, investment advisory fees earned and voluntarily waived were $658,262 and $98,739, respectively.

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 the relative average net assets of each fund/portfolio, subject to an annual minimum fee. For the six months ended April 30, 2009, administrative services fees earned by SSB (including out-of-pocket expenses) were $51,424.

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. Beginning in 2008, the Independent Trustees can elect to receive up to 100% of their annual retainer in shares of the Fund. During the six months ended April 30, 2009, 12,541 shares were issued through the directors compensation plan. Trustees as a group own less than 1% of the Fund's outstanding 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, 2009, Merrill was paid $13,213 for its services by the Fund.

Note 4. Line of Credit

The Fund had 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. In December 2008, the Citibank Agreement was terminated and replaced by a line of credit with SSB (the "SSB Agreement"), dated December 12, 2008, primarily to leverage its investment portfolio. Under the SSB Agreement, the Fund may borrow the least of: a) $75,000,000; b) an amount that is no greater than 25% of the Fund's total assets minus the sum of liabilities (other than aggregate indebtedness constituting leverage); and c) the Borrowing Base as defined in the SSB Agreement. The SSB Agreement is subject to annual renewal in December 2009. At April 30, 2009, the Fund had loans outstanding under the SSB Agreement of $28,500,000. During the six months ended April 30, 2009, the Fund had borrowin gs under the agreements as follows:

Average Daily Loan Balance		Weighted Average Interest Rate %			Maximum Daily Loan Outstanding
$	32,289,724		1.986	%	$	58,610,000

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 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.

April 30, 2009 (unaudited)

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. There is no guarantee that the Fund's borrowing arrangements or other arrangements for obtaining leverage will continue to be available, or if available, will be available on terms and conditions acceptable to the Fund. Expiration or termination of available financing for leveraged positions, can result in adverse effects to its access to liquidity and its ability to maintain leverage positions, and may cause the Fund to incur losses. Unfavorable economic conditions also could increase funding costs, limit access to the capital markets or result in a decision by lenders not to extend credit to the Fund. In addition, a decline in market value of the Fund's assets may have particular adverse consequences in instances where they have borrowed money based on the market value of those assets. A decrease in market value of those assets may result in the lender requiring the Fund to sell assets at a time when it may not be in the Fund's best interest to do so.

Note 5. Purchases and Sales of Securities

For the six months ended April 30, 2009, purchases and sales of investment securities (excluding short-term investments) were $24,303,612 and $55,015,074, respectively.

At April 30, 2009, 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 $208,714,233, $1,435,508, $(72,866,046) and $(71,430,538), respectively.

Note 6. Fund Shares

The Fund has one class of shares of beneficial interest, par value $.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, 2009 (unaudited)		For the Year Ended October 31, 2008
Shares issued through the directors compensation plan		12,541		6,420
Shares issued through reinvestment of dividends		49,063		—
Net increase		61,604		6,420

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.

Note 9. Recent Accounting Pronouncements

In March 2008, FASB issued Statement of Financial Accounting Standards No. 161, Disclosures about Derivative Instruments and Hedging Activities ("FAS 161"), an amendment of FASB Statement No. 133. FAS 161 requires enhanced disclosures about (a) how and why an entity uses derivative instruments, (b) how derivative instruments and hedging activities are accounted for, and (c) how derivative instruments and related hedging activities affect a fund's financial position, financial performance, and cash flows. Management of the Fund does not believe the adoption of FAS 161 will materially impact the financial statement amounts, but will require additional disclosures. This will include qualitative and quantitative disclosures on derivative positions existing at period end and the effect of using der ivatives during the reporting period. FAS 161 is effective for financial statements issued for fiscal years and interim periods beginning after November 15, 2008.

27

Credit Suisse High Yield Bond Fund

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

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 Investment Company Act of 1940 (the "Independent Trustees"), is required annually to review and re-approve the terms of the Fund's investment advisory agreement. During the most recent six months covered by this report, the Board reviewed and re-approved an investment advisory agreement (the "Advisory Agreement") with Credit Suisse Asset Management, LLC ("Credit Suisse").

More specifically, at a meeting held on November 19-20, 2008, 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 for Credit Suisse was provided to the Board, as were responses of Credit Suisse to a detailed series of requests submitted by the Independent Trustees' independent legal counsel on their behalf. The Board reviewed and analyzed these materials, which included, among other things, information about the background and experience of senior management and investment personnel of Credit Suisse. In this regard, the Board specifically reviewed the qualifications, background and responsibilities of the individual primarily responsible for day-to-day portfolio management services for the Fund.

In addition, the Board considered the investment and legal compliance programs of Credit Suisse, including their compliance policies and procedures and reports of the Fund's Chief Compliance Officer.

The Board also evaluated the ability of Credit Suisse, based on its resources, reputation and other attributes, to attract and retain qualified investment professionals, including research, advisory, and supervisory personnel.

Finally, the Board considered preliminary information from Credit Suisse's corporate parent about its search for a strategic partner for part of its asset management business. In reaching its determination to continue the Advisory Agreement, the Board relied upon Credit Suisse's undertaking and assurances to continue providing quality management, personnel and other resources necessary to continue providing advisory services of a nature, extent and quality at least comparable to those currently provided to the Fund.

Based on the above factors, together with those referenced below, the Board concluded that it was 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 the performance results of the Fund in comparison to the performance of a universe of leveraged, closed-end high current yield funds (the "Performance Universe"). Lipper Inc. ("Lipper"), an independent provider of investment company data, determined the Performance Universe for the Fund and provided the comparative data. The Board noted that the Fund had underperformed the median performance of the funds in its Performance Universe in some periods and outperformed the median performance of its Performance Universe in other periods.

The Board also considered information regarding the Fund's total expense ratio and its various components in comparison to expense information for a group of funds that was determined to be most similar to the Fund (the "Peer Group") and to the median expenses of a broader universe of relevant funds (the "Expense Universe"),

28

Credit Suisse High Yield Bond Fund

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

which comparative data was provided by Lipper. The Board noted that the overall expense ratio of the Fund is higher than the median overall expense ratios of the Fund's Peer Group and Expense Universe, including and excluding investment- related expenses and taxes. The Board also noted that the Fund's actual non-management expense ratio was below the median non-management expense ratios of its Peer Group and Expense Universe.

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

Investment Advisory Fee Rate

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

Additionally, the Board 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 that of the other funds in its Peer Group and Expense Universe. The Board observed that the Advisory Agreement Rate and combined investment advisory and administration fee rates were higher than the median rates of funds in the Fund's Peer Group. The Board also noted, however, that Credit Suisse was voluntarily waiving a portion of its advisory fee. The Board further 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. The Board concluded that these and other 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 and on revenues earned from 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 derived from providing these services to the Fund were not excessive.

Economies of Scale

The Board 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 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 Fund shareholders sharing in potential economies of scale.

Information about Services to Other Clients

The Board considered information about the nature and extent of services and fee rates offered by Credit Suisse to other clients, including other registered investment companies, separate accounts 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 not excessive given the nature and extent of services offered and comparison with rates charged to other clients.

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

Other Benefits to Credit Suisse

The Board also considered information regarding potential "fall-out" or ancillary benefits received by Credit Suisse and its affiliates as a result of their relationship with the Fund. In particular, the Board considered that Credit Suisse may gain certain reputational benefits from managing the Fund.

Other Factors and Broader Review

As discussed above, the Board reviews detailed materials received from Credit Suisse as part of the annual re-approval process. 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 quarterly, which include, among other things, detailed portfolio and market reviews and detailed fund performance reports.

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 shareholders. Accordingly, the Board members unanimously re-approved the Advisory Agreement.

Credit Suisse High Yield Bond Fund

Dividend Reinvestment and Cash Purchase Plan (unaudited)

Credit Suisse High Yield Bond Fund (the "Fund") offers a Dividend Reinvestment and Cash Purchase Plan (the "Plan") to its common stockholders. The Plan offers common stockholders a prompt and simple way to reinvest net investment income dividends and capital gains and other periodic distributions in shares of the Fund's common stock. Computershare Trust Company, N.A. ("Computershare") acts as Plan Agent for stockholders in administering the Plan.

Participation in the Plan is voluntary. In order to participate in the Plan, you must be a registered holder of at least one share of stock of the Fund. If you are a beneficial owner of the Fund having your shares registered in the name of a bank, broker or other nominee, you must first make arrangements with the organization in whose name your shares are registered to have the shares transferred into your own name. Registered shareholders can join the Plan via the Internet by going to www.computershare.com, authenticating your online account, agreeing to the Terms and Conditions of online "Account Access" and completing an online Plan Enrollment Form. Alternatively, you can complete the Plan Enrollment Form and return it to Computershare at the address below.

By participating in the Plan, your dividends and distributions will be promptly paid to you in additional shares of common stock of the Fund. The number of shares to be issued to you will be determined by dividing the total amount of the distribution payable to you by the greater of (i) the net asset value per share ("NAV") of the Fund's common stock on the payment date, or (ii) 95% of the market price per share of the Fund's common stock on the payment date. If the NAV of the Fund's common stock is greater than the market price (plus estimated brokerage commissions) on the payment date, then Computershare (or a broker-dealer selected by Computershare) shall endeavor to apply the amount of such distribution on your shares to purchase shares of Fund common stock in the open market.

You should be aware that all net investment income dividends and capital gain distributions are taxable to you as ordinary income and capital gain, respectively, whether received in cash or reinvested in additional shares of the Fund's common stock.

The Plan also permits participants to purchase shares of the Fund through Computershare. You may invest $100 or more monthly, with a maximum of $100,000 in any annual period. Computershare will purchase shares for you on the open market on the 25th of each month or the next trading day if the 25th is not a trading day.

There is no service fee payable by Plan participants for dividend reinvestment. For voluntary cash payments, Plan participants must pay a service fee of $5.00 per transaction. Plan participants will also be charged a pro rata share of the brokerage commissions for all open market purchases ($0.03 per share as of October 2006). Participants will also be charged a service fee of $5.00 for each sale and brokerage commissions of $0.03 per share (as of October 2006).

You may terminate your participation in the Plan at any time by requesting a certificate or a sale of your shares held in the Plan. Your withdrawal will be effective immediately if your notice is received by Computershare prior to any dividend or distribution record date; otherwise, such termination will be effective only with respect to any subsequent dividend or distribution. Your dividend participation option will remain the same unless you withdraw all of your whole and fractional Plan shares, in which case your participation in the Plan will be terminated and you will receive subsequent dividends and capital gains distributions in cash instead of shares.
