Annual Investment Adviser's Report

October 31, 2011 (unaudited)

December 1, 2011

We are pleased to present this Annual Report which covers the activities of the Credit Suisse High Yield Bond Fund for the year ended October 31, 2011.

Dear Shareholder:

Performance Summary

11/1/10 – 10/31/11

Fund & Benchmark	Performance
Total Return (based on NAV)1		6.84	%
Total Return (based on market value)1		12.51	%
BofA Merrill Lynch US High Yield Master II Constrained Index2		4.82	%

Market Review: Lowest default rates since 2008

The year ended October 31, 2011 was a volatile one for the high yield market. The BofA Merrill Lynch US High Yield Master II Constrained Index (the "Index"), the Fund's benchmark, registered a return of 4.82% for the period. Although there was optimism in the first half of the year, it was tempered by escalating concerns over systemic risks in Europe and the United States during the third quarter. As a result, high yield spreads widened to +836 basis points versus the Treasury market in September then tightened to end the year at +713 basis points. Yields ended the period at 8.24%.

From a quality point-of-view, CC-rated securities and C-rated underperformed, returning -3.5% and -17.0%, respectively. BB and B-rated securities posted the highest returns of 5.0% and 5.1%, respectively. On a sector basis, the top performers were software/services, food and drug retailers, and REITs. Conversely, electricity distribution/transportation, monoline insurance, and integrated energy were the biggest detractors from overall performance during the period.

High yield default rates have fallen to their lowest levels since early 2008 with the trailing 12-month issuer-weighted global default rate, as measured by Moody's, declining steadily from 3.8% in October 2010 to 1.9% in October 2011. This rate is well below the historical average of 4.45% and is forecasted to increase to 2.25% over the next 12 months. The percentage of U.S. high yield securities that are "distressed," defined as those trading at spreads of more than 1,000 basis points over Treasuries, fell to a low of 5.0% through May 2011, before rising again to finish October 2011 at 16.1% — up from 10.5% year over year.

High yield issue volume for the period, according to JP Morgan, was more than $274 billion — generally in line with last year's figure of nearly $284 billion. New issue activity was greatest during the second quarter of 2011, with over $92 billion in new issues. There was a considerable decrease in activity in the third quarter as issuance dropped to less than $26 billion. And according to Lipper, high-yield mutual funds saw eight months of positive flows during the year for a total net inflow of more than $9 billion — it's worth noting that this figure includes a record monthly inflow of nearly $7 billion in October 2011.

Strategic Review and Outlook: Cautiously optimistic going forward

For the 12-month period ended October 31, 2011, the Fund outperformed the benchmark. An underweight to the banking and wireless sectors as well as superior credit selection in the gaming sector contributed positively to returns. Conversely, security selection in the restaurants and chemicals sectors hurt relative returns.

We believe recent dislocations in credit markets have presented opportunities for high yield portfolios to selectively purchase bonds at attractive yields. Our portfolio exposures remain defensive, with an emphasis on

senior secured bonds. In addition, we continue to maintain an overweight to B-rated bonds with the best risk-return profiles, while underweighting the most aggressive CC-rated components of the Index. The Fund has also focused on securities with less interest rate sensitivity and has maintained its exposure to shorter duration bonds. From a sector perspective, we have a positive view on energy, technology and media. We continue to remain cautious with respect to consumer-driven industries where asset quality is low.

The broad macroeconomic data, such as inconsistent U.S. economic trends and Eurozone concerns, cause us to remain cautious for the near-term. However, on a fundamental basis, high yield companies have focused on deleveraging and extending maturities since early 2009—despite the volatility and negative sentiment that has dominated the landscape. These improved fundamentals continue to support the expectations that defaults will be lower than historical averages for 2012 and 2013.

Thomas J. Flannery Chief Investment Officer*	John Popp Chief Executive Officer and President**

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 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.

The views of the Fund's management are as of the date of the letter and the Fund holdings described in this document are as of October 31, 2011; these views and Fund holdings may have changed subsequent to these dates. Nothing in this document is a recommendation to purchase or sell securities.

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.

¹  Per share information is calculated using the average shares outstanding method.

²  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.

Credit Suisse High Yield Bond Fund

Notes to Financial Statements

October 31, 2011

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 (the "1940 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. 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, 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. Equity investments are generally categorized as Level 1. Investments in open-end investment companies are valued at their net asset value each business day and are generally categorized as Level 1. 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. Debt securities are generally categorized as Level 2. Forward currency contracts are valued at the prevailing forward exchange rate of the underlying currencies and are generally categorized as Level 2. 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 and are generally categorized as Level 3. At October 31, 2011, the Fund held 0.06% 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 $1,700,782 and fair value of $118,590. The Fund's estimate of fair value assumes a willing buyer and a willing seller neither acting under 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.

In accordance with the authoritative guidance on fair value measurements and disclosures under accounting principles generally accepted in the United States of America ("GAAP"), the Fund discloses the fair value of its investments in a hierarchy that prioritizes the inputs to valuation techniques used to measure the fair value. In accordance with GAAP, 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. GAAP 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

18

Credit Suisse High Yield Bond Fund

Notes to Financial Statements (continued)

October 31, 2011

assumptions market participants would use in pricing the asset or liability developed based on the best information available in the circumstances. In accordance with the Fund's valuation procedures, factors used in determining value may include, but are not limited to, the type of the security, the size of the holding, the initial cost of the security, the existence of any contractual restrictions on the security's disposition, the price and extent of public trading in similar securities of the issuer or of comparable companies, quotations or evaluated prices from broker-dealers and/or pricing services, information obtained from the issuer, analysts, and/or the appropriate stock exchange (for exchange-traded securities), an analysis of the company's or issuer's financial statements, an evaluation of the forces that influence the issuer and the market(s) in which the security is purchased and sold and with respect to debt securities, the maturity, coupon, creditworthiness, currency denomination, and the movement of the market in which the security is normally traded. 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 October 31, 2011 in valuing the Fund's investments carried at value:

	Level 1		Level 2			Level 3		Total
Investments in Securities
Corporate Bonds	$	—	$	268,325,035		$	67	$	268,325,102

Common Stocks		915,744		—			—		915,744
Preferred Stocks		352,784		—			—		352,784
Warrants		1,279		—			118,523		119,802

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

The following is a reconciliation of investments as of October 31, 2011 in which significant unobservable inputs (Level 3) were used in determining value. Transfers in or out of Level 3 represent the beginning value of any security or instrument where a change in the level has occurred from the beginning to the end of the period.

19

Credit Suisse High Yield Bond Fund

Notes to Financial Statements (continued)

October 31, 2011

The Fund adopted FASB amendments to authoritative guidance which require the Fund to disclose details of significant transfers in and out of Level 1 and Level 2 measurements and the reasons for the transfers. For the year ended October 31, 2011, there were no significant transfers in and out of Level 1 and Level 2.

B) DERIVATIVE INSTRUMENTS AND HEDGING ACTIVITIES — The Fund adopted amendments to authoritative guidance on disclosures about derivative instruments and hedging activities which require that the Fund disclose (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.

Fair Values of Derivative Instruments as of October 31, 2011

	Asset Derivatives			Liability Derivatives
	Balance Sheet Location	Fair Value		Balance Sheet Location	Fair Value
	Net Assets –			Liabilities –
Forward Foreign	Unrealized			Unrealized
Currency Contracts	Appreciation	$	0	Depreciation	$	702,440	*

*  Includes cumulative appreciation/depreciation of forward foreign currency contracts as reported in the Statement of Assets and Liabilities and Notes to Financial Statements.

Effect of Derivative Instruments on the Statement of Operations

Amount of Realized Gain (Loss) on Derivatives Recognized in Income Forward Foreign Currency Contracts	$	167,710
Change in Unrealized Appreciation (Depreciation) on Derivatives Recognized in Income Forward Foreign Currency Contracts	$	(765,771	)

The notional amount of forward foreign currency contracts at period end are reflected in the Notes to Financial Statements. The notional amounts of forward foreign currency contracts at each month end throughout the reporting period averaged approximately 6.8% of net assets of the Fund.

C) 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.

D) 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.

20

Credit Suisse High Yield Bond Fund

Notes to Financial Statements (continued)

October 31, 2011

E) 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 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 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.

F) 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.

The Fund adopted the authoritative guidance for uncertainty in income taxes and recognizes a tax benefit or liability from an uncertain position only if it is more likely than not that the position is sustainable based solely on its technical merits and consideration of the relevant taxing authority's widely understood administrative practices and procedures. 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.

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 these estimates.

H) 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 a short-term variable rate time deposit issued by State Street Bank and Trust Company ("SSB"), the Fund's custodian. The short-term time deposit issued by SSB is a variable rate account classified as a short-term investment.

I) 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.

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

21

Credit Suisse High Yield Bond Fund

Notes to Financial Statements (continued)

October 31, 2011

contracts and from unanticipated movements in the value of a foreign currency. The Fund will enter into forward foreign currency contracts primarily for hedging foreign currency risk. 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 October 31, 2011, the Fund had the following open forward foreign currency contract:

Forward Foreign Currency to be Purchased (Local)		Forward Foreign Currency to be Sold (Local)		Expiration Date	Counterparty	Value on Settlement Date			Current Value			Unrealized Appreciation/ (Depreciation)
USD	25,924,730	EUR	19,100,000	01/13/12	Morgan Stanley	$	(25,924,730	)	$	(26,627,170	)	$	(702,440	)

Currency Abbreviations:

EUR – Euro Currency

USD – United States Dollar

K) 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 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 year ended October 31, 2011, total earnings from the Fund's investment in cash collateral received in connection with securities lending arrangements was $108,896 of which $43 was rebated to borrowers (brokers). The Fund retained $87,169 in income from the cash collateral investment, and SSB, as lending agent, was paid $21,684. Securities lending income is accrued as earned.

L) 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 the Fund's net asset value.

M) SUBSEQUENT EVENTS — In preparing the financial statements as of October 31, 2011, management considered the impact of subsequent events for potential recognition or disclosure in these financial statements through the date of release of this report.

On December 8, 2011, the Fund filed a "shelf" registration statement with the SEC, which would permit the Fund to issue up to $50 million in shares of common stock through one or more public offerings. Under the shelf registration statement, the Fund may sell the Fund's common shares in one or more at-the-market offerings when market conditions are considered favorable. Such shares would only be issued when the premium to net asset value is greater than the costs associated with the transaction. Any proceeds raised would be used for investment purposes.

October 31, 2011

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. Effective January 1, 2011, Credit Suisse agreed to waive 0.15% of the fees payable under the Advisory Agreement up to $200 million and 0.25% of the fees payable under the Advisory Agreement on the next $50 million. For the year ended October 31, 2011, investment advisory fees earned and voluntarily waived were $2,974,576 and $428,509, respectively. Credit Suisse will not recapture from the Fund any fees it waived during the year ended October 31, 2011. Fee waivers and expense reimbursements are voluntary and may be discontinued by Credit Suisse at any time.

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 year ended October 31, 2011, administrative services fees earned by SSB (including out-of-pocket expenses) were $141,111.

The Independent Trustees receive fifty percent (50%) of their annual retainer in the form of shares. Since 2008, the Independent Trustees have been able to elect to receive up to 100% of their annual retainer in shares of the Fund. During the year ended October 31, 2011, 16,879 shares were issued through the trustees 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 services. For the year ended October 31, 2011, Merrill was paid $31,780 for its services by the Fund.

Note 4. Line of Credit

The Fund has a line of credit provided by SSB primarily to leverage its investment portfolio (the "SSB Agreement"). At October 31, 2011, under the SSB Agreement, the Fund may borrow the least of: a) $100,000,000; b) an amount that is no greater than 31% 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. Effective December 9, 2011, the Fund may borrow the least of: a) $140,000,000; b) an amount that is no greater than 33 1/3% 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. At October 31, 2011, the Fund had loans outstanding under the Agreement of $89,000,000. During the year ended October 31, 2011, the Fund had borrowings under the Agreement as follows:

Average Daily Loan Balance		Weighted Average Interest Rate %			Maximum Daily Loan Outstanding
$	91,963,014		1.289	%	$	100,000,000

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

23

Credit Suisse High Yield Bond Fund

Notes to Financial Statements (continued)

October 31, 2011

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.

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 1940 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 year ended October 31, 2011, purchases and sales of investment securities (excluding short-term investments) were $249,499,845 and $202,099,894, 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 of the Fund were as follows:

	For the Year Ended October 31, 2011		For the Year Ended October 31, 2010
Shares issued through the trustees compensation plan		16,879		38,696
Shares issued through rights offering		—		18,725,102
Shares issued through reinvestment of dividends		269,290		230,947
Net increase		286,169		18,994,745

Note 7. Federal Income Taxes

Income and capital gain distributions are determined in accordance with federal income tax regulations, which may differ from GAAP.

24

Credit Suisse High Yield Bond Fund

Notes to Financial Statements (continued)

October 31, 2011

The tax characteristics of dividends and distributions paid during the years ended October 31, 2011 and 2010, respectively, by the Fund were as follows:

Ordinary Income				Return of Capital
2011		2010		2011		2010
$	23,874,498	$	17,200,723	$	0	$	631,150

The tax basis components of distributable earnings differ from the amounts reflected in the Statement of Assets and Liabilities by temporary book/tax differences. These differences are primarily due to losses deferred on wash sales, income from defaulted bonds and mark to market of forward contracts. At October 31, 2011, the components of distributable earnings on a tax basis were as follows:

Undistributed net investment income	$	47,843
Accumulated realized loss		(87,743,811	)
Unrealized depreciation		(10,550,731	)
	$	(98,246,699	)

At October 31, 2011, the Fund had capital loss carryforwards available to offset possible future capital gains as follows:

Expires October 31,
2012		2013		2014		2016		2017		2018
$	6,096,544	$	1,583,878	$	8,944,708	$	24,144,149	$	40,767,194	$	6,207,338

During the tax year ended October 31, 2011, the Fund utilized $3,455,175 of the capital loss carryforwards and $4,836,064 of the capital loss carryforwards expired.

Under the Regulated Investment Company Modernization Act of 2010, the Fund will be permitted to carry forward capital losses incurred in taxable years beginning after December 22, 2010 for an unlimited period. However, any losses incurred during those future taxable years will be required to be utilized prior to the losses incurred in pre-enactment taxable years. As a result of this ordering rule, pre-enactment capital loss carryforwards may be more likely to expire unused. Additionally, post-enactment capital losses that are carried forward will retain their character as either short-term or long-term capital losses rather than being considered all short-term as under previous law. It is uncertain whether the Fund will be able to realize the full benefits of the capital loss carryforwards before they expire.

At October 31, 2011, 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 $313,023,414, $10,303,645, $(20,851,773) and $(10,548,128), respectively.

At October 31, 2011, the Fund reclassified $394,783 to net investment loss and $4,441,281 to accumulated net realized loss from investments from paid in capital, to adjust for current period permanent book/tax differences. These permanent differences are due to differing book/tax treatments of foreign currency gain/(loss), defaulted bonds and expiration of capital loss carryforwards. Net assets were not affected by these reclassifications.

Note 8. Rights Offering

On August 25, 2010, the Board of Trustees of the Fund announced the approval of the transferable rights offering for the Fund. The Fund issued to its shareholders of record as of the close of business on September 13,

25

Credit Suisse High Yield Bond Fund

Notes to Financial Statements (continued)

October 31, 2011

2010, transferable rights (with an expiration date of October 15, 2010) to subscribe for up to an aggregate of 18,725,102 Common Shares of Beneficial Interest ("Shares") of the Fund at a rate of one Share for three rights held at the subcription price of $2.72 per share. During October 2010, the Fund issued a total of 18,725,102 Shares upon the exercise of such rights. Rights' offering costs of $485,000 was charged to capital during the fiscal year ended October 31, 2010, and $62,923 was charged to capital during the year ended October 31, 2011. The net asset value of the Fund's Shares were reduced by $0.07 as a result of the Offer, which includes the effect of the offering costs.

Note 9. 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 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.

If your shares of common stock of the Fund are registered in your own name, you will automatically participate in the Plan, unless you have indicated that you do not wish to participate and instead wish to receive dividends and capital gains distributions in cash. 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 notifying Computershare or requesting 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.

CREDIT SUISSE ASSET MANAGEMENT, LLC

CREDIT SUISSE FUNDS

CREDIT SUISSE CLOSED-END FUNDS

PROXY VOTING POLICY AND PROCEDURES

Introduction

Credit Suisse Asset Management, LLC (“Credit Suisse”) is a fiduciary that owes each of its clients duties of care and loyalty with respect to proxy voting.  The duty of care requires Credit Suisse to monitor corporate events and to vote proxies.  To satisfy its duty of loyalty, Credit Suisse must cast proxy votes in the best interests of each of its clients.

The Credit Suisse Funds and Credit Suisse Closed-End Funds (the “Funds”), which have engaged Credit Suisse Asset Management, LLC as their investment adviser, are of the belief that the proxy voting process is a means of addressing corporate governance issues and encouraging corporate actions both of which can enhance shareholder value.

Policy

The Proxy Voting Policy (the “Policy”) set forth below is designed to ensure that proxies are voted in the best interests of Credit Suisse’s clients.  The Policy addresses particular issues and gives a general indication of how Credit Suisse will vote proxies.  The Policy is not exhaustive and does not include all potential issues.

Proxy Voting Committee

The Proxy Voting Committee will consist of a member of the Portfolio Management Department, a member of the Legal and Compliance Department, and a member of the Operations Department (or their designees).  The purpose of the Proxy Voting Committee is to administer the voting of all clients’ proxies in accordance with the Policy.  The Proxy Voting Committee will review the Policy annually to ensure that it is designed to promote the best interests of Credit Suisse’s clients.

For the reasons disclosed below under “Conflicts,” the Proxy Voting Committee has engaged the services of an independent third party (initially, Risk Metrics Group’s ISS Governance Services Unit (“ISS”)) to assist in issue analysis and vote recommendation for proxy proposals.  Proxy proposals addressed by the Policy will be voted in accordance with the Policy.  Proxy proposals addressed by the Policy that require a case-by-case analysis will be voted in accordance with the vote recommendation of ISS.  Proxy proposals not addressed by the Policy will also be voted in accordance with the vote recommendation of ISS.  To the extent that the Proxy Voting Committee

5

proposes to deviate from the Policy or the ISS vote recommendation, the Committee shall obtain client consent as described below.

Credit Suisse investment professionals may submit a written recommendation to the Proxy Voting Committee to vote in a manner inconsistent with the Policy and/or the recommendation of ISS.  Such recommendation will set forth its basis and rationale.  In addition, the investment professional must confirm in writing that he/she is not aware of any conflicts of interest concerning the proxy matter or provide a full and complete description of the conflict.

Conflicts

Credit Suisse is part of the asset management business of Credit Suisse one of the world’s leading banks.  As part of a global, full service investment-bank, broker-dealer, and asset-management organization, Credit Suisse and its affiliates and personnel may have multiple advisory, transactional, financial, and other interests in securities, instruments, and companies that may be purchased or sold by Credit Suisse for its clients’ accounts.  The interests of Credit Suisse and/or its affiliates and personnel may conflict with the interests of Credit Suisse’s clients in connection with any proxy issue.  In addition, Credit Suisse may not be able to identify all of the conflicts of interest relating to any proxy matter.

Consent

In each and every instance in which the Proxy Voting Committee favors voting in a manner that is inconsistent with the Policy or the vote recommendation of ISS (including proxy proposals addressed and not addressed by the Policy), it shall disclose to the client conflicts of interest information and obtain client consent to vote.  Where the client is a Fund, disclosure shall be made to any one director who is not an “interested person,” as that term is defined under the Investment Company Act of 1940, as amended, of the Fund.

Recordkeeping

Credit Suisse is required to maintain in an easily accessible place for six years all records relating to proxy voting.

These records include the following:

·a copy of the Policy;

·a copy of each proxy statement received on behalf of Credit Suisse clients;

·a record of each vote cast on behalf of Credit Suisse clients;

6

·a copy of all documents created by Credit Suisse personnel that were material to making a decision on a vote or that memorializes the basis for the decision; and

·a copy of each written request by a client for information on how Credit Suisse voted proxies, as well as a copy of any written response.

Credit Suisse reserves the right to maintain certain required proxy records with ISS in accordance with all applicable regulations.

Disclosure

Credit Suisse will describe the Policy to each client.  Upon request, Credit Suisse will provide any client with a copy of the Policy.  Credit Suisse will also disclose to its clients how they can obtain information on their proxy votes.

ISS will capture data necessary for Funds to file Form N-PX on an annual basis concerning their proxy voting record in accordance with applicable law.

Procedures

The Proxy Voting Committee will administer the voting of all client proxies. Credit Suisse has engaged ISS as an independent third party proxy voting service to assist in the voting of client proxies.  ISS will coordinate with each client’s custodian to ensure that proxy materials reviewed by the custodians are processed in a timely fashion.  ISS will provide Credit Suisse with an analysis of proxy issues and a vote recommendation for proxy proposals.  ISS will refer proxies to the Proxy Voting Committee for instructions when the application of the Policy is not clear.  The Proxy Voting Committee will notify ISS of any changes to the Policy or deviating thereof.

Item 8.  Portfolio Managers of Closed-End Management Investment Companies.

Information pertaining to the Chief Investment Officer of the Credit Suisse High Yield Bond Fund, as of October 31, 2011, is set forth below.

Thomas J. Flannery
Chief Investment
Officer Since 2010
Year of Birth: 1974 Managing Director of Credit Suisse and Head of the Credit Suisse US High Yield Management Team; Associated with Credit Suisse Group A.G. since 1998; Officer of other Credit Suisse Funds

18

Registered Investment Companies, Pooled Investment Vehicles and Other Accounts Managed

As reported to the Registrant, the information in the following table reflects the number of registered investment companies, pooled investment vehicles and other accounts managed by Mr. Flannery and the total assets managed within each category as of October 31, 2011.

	Registered Investment  Companies		Other Pooled Investment  Vehicles		Other Accounts
Thomas J. Flannery	3	$623 million	27	$10,202 million	10	$2,132 million

As of October 31, 2011, Mr. Flannery manages 22 accounts which have total assets under management of $9,048 million, and which have additional fees based on the performance of the accounts.

Potential Conflicts of Interest

It is possible that conflicts of interest may arise in connection with the portfolio managers’ management of the Funds’ investments on the one hand and the investments of other accounts on the other. For example, the portfolio managers may have conflicts of interest in allocating management time, resources and investment opportunities among the Funds and other accounts they advise. In addition due to differences in the investment strategies or restrictions between the Funds and the other accounts, the portfolio managers may take action with respect to another account that differs from the action taken with respect to the Funds.  Credit Suisse has adopted policies and procedures that are designed to minimize the effects of these conflicts.

If Credit Suisse believes that the purchase or sale of a security is in the best interest of more than one client, it may (but is not obligated to) aggregate the orders to be sold or purchased to seek favorable execution or lower brokerage commissions, to the extent permitted by applicable laws and regulations.  Credit Suisse may aggregate orders if all participating client accounts benefit equally (i.e., all receive an average price of the aggregated orders). In the event Credit Suisse aggregates an order for participating accounts, the method of allocation will generally be determined prior to the trade execution. Although no specific method of allocation of transactions (as well as expenses incurred in the transactions) is expected to be used, allocations will be designed to ensure that over time all clients receive fair treatment consistent with Credit Suisse’s fiduciary duty to its clients (including its duty to seek to obtain best execution of client trades). The accounts aggregated may include registered and unregistered investment companies managed by Credit Suisse’s affiliates and accounts in which Credit Suisse’s officers, directors, agents, employees or affiliates own interests.

19

Credit Suisse may not be able to aggregate securities transactions for clients who direct the use of a particular broker-dealer, and the client also may not benefit from any improved execution or lower commissions that may be available for such transactions.

Compensation

Mr. Flannery is compensated for his services by Credit Suisse. His compensation consists of a fixed base salary and a discretionary bonus that is not tied by formula to the performance of any fund or account. The factors taken into account in determining his bonus include the Fund’s performance, assets held in the Fund and other accounts managed by him, business growth, team work, management, corporate citizenship, etc.

A portion of the bonus may be paid in phantom shares of Credit Suisse Group A.G. stock as deferred compensation. Phantom shares are shares representing an unsecured right to receive on a particular date a specified number of registered shares subject to certain terms and conditions. A portion of the bonus will receive the notional return of the fund(s) the portfolio manager manages and a portion of the bonus will receive the notional return of a basket of other Credit Suisse funds along the product line of the portfolio manager.

Like all employees of Credit Suisse Group A.G., portfolio managers participate in Credit Suisse Group A.G.’s profit sharing and 401(k) plans.

Securities Ownership.  As of October 31, 2011, Mr. Flannery did not own any shares of the registrant.

Item 9. Purchases of Equity Securities by Closed-End Management Investment Company and Affiliated Purchasers.

EX-99.CODEETH

EX-99.CODE ETHICS

EXHIBIT 12(a)(1)

CODE OF ETHICS

CREDIT SUISSE FUNDS

CREDIT SUISSE CLOSED-END FUNDS

CODE OF ETHICS FOR SENIOR OFFICERS

Preamble

Section 406 of the Sarbanes-Oxley Act of 2002 directs that rules be adopted disclosing whether a company has a code of ethics for senior financial officers.  The Securities and Exchange Commission (the “SEC”) has adopted rules requiring annual disclosure of an investment company’s code of ethics applicable to the company’s principal executive as well as principal financial officers, if such a code has been adopted.  In response, the above Funds (each a “Fund”, and together the “Funds”) have adopted this Code of Ethics.

Statement of Policy

It is the obligation of the senior officers of the Funds to provide full, fair, timely and comprehensible disclosure—financial and otherwise—to Fund shareholders, regulatory authorities and the general public.  In fulfilling that obligation, senior officers must act ethically, honestly and diligently.  This Code is intended to enunciate guidelines to be followed by persons who serve the Funds in senior officerships.  No Code can address every situation that a senior officer might face; however, as a guiding principle, senior officers should strive to implement the spirit as well as the

1

letter of applicable laws, rules and regulations, and to provide the type of clear and complete disclosure and information Fund shareholders have a right to expect.

The purpose of this Code of Ethics is to promote high standards of ethical conduct by Covered Persons (as defined below) in their capacities as officers of the Funds, to instruct them as to what is considered to be inappropriate and unacceptable conduct or activities for officers and to prohibit such conduct or activities.  This Code supplements other policies that the Funds and their adviser have adopted or may adopt in the future with which Fund officers are also required to comply (e.g., code of ethics relating to personal trading and conduct).

Covered Persons

This Code of Ethics applies to those persons appointed by the Fund’s Board of Directors as Chief Executive Officer, President, Chief Financial Officer and Chief Accounting Officer, or persons performing similar functions.  It is recognized that each of such persons currently is a full-time employee of Credit Suisse Asset Management LLC (“Credit Suisse”), each Fund’s investment adviser.

Promotion of Honest and Ethical Conduct

In serving as an officer of the Funds, each Covered Person must maintain high standards of honesty and ethical conduct and must encourage his colleagues who provide services to the Funds, whether directly or indirectly, to do the same.

Each Covered Person understands that as an officer of a Fund, he has a duty to act in the best interests of the Fund and its shareholders.  The interests of other Credit Suisse clients or Credit Suisse itself or the Covered Person’s personal interests should not be allowed to compromise

2

the Covered Person’s fulfilling his duties as an officer of the Fund.  The governing Boards of the Funds recognize that the Covered Persons are also officers or employees of Credit Suisse.  Furthermore, the governing Boards of the Funds recognize that, subject to the Covered Person’s fiduciary duties to the Funds, the Covered Persons will in the normal course of their duties (whether formally for the Funds or for Credit Suisse, or for both) be involved in establishing policies and implementing decisions that will have different effects on Credit Suisse and the Funds.  The governing Boards of the Funds recognize that the participation of the Covered Persons in such activities is inherent in the contractual relationship between the Funds and Credit Suisse and/or its affiliates, and is consistent with the expectation of the governing Boards of the performance by the Covered Persons of their duties as officers of the Funds.

If a Covered Person believes that his responsibilities as an officer or employee of Credit Suisse are likely to materially compromise his objectivity or his ability to perform the duties of his role as an officer of the Funds, he should consult with Credit Suisse ‘s general counsel, the Funds’ chief legal officer or outside counsel, or counsel to the independent Directors/Trustees of the relevant Fund or Funds.  Under appropriate circumstances, a Covered Person should also consider whether to present the matter to the Directors/Trustees of the relevant Fund or Funds or a committee thereof.

No Covered Person shall suggest that any person providing, or soliciting to be retained to provide, services to a Fund give a gift or an economic benefit of any kind to him in connection with the person’s retention or the provision of services.

3

Promotion of Full, Fair, Accurate, Timely and Understandable Disclosure

No Covered Person shall create or further the creation of false or misleading information in any SEC filing or report to Fund shareholders.  No Covered Person shall conceal or fail to disclose information within the Covered Person’s possession legally required to be disclosed or necessary to make the disclosure made not misleading.  If a Covered Person shall become aware that information filed with the SEC or made available to the public contains any false or misleading information or omits to disclose necessary information, he shall promptly report it to Credit Suisse’s general counsel or Fund counsel, who shall advise such Covered Person whether corrective action is necessary or appropriate.

Each Covered Person, consistent with his responsibilities, shall exercise appropriate supervision over, and shall assist, relevant Fund service providers in developing financial information and other disclosure that complies with relevant law and presents information in a clear, comprehensible and complete manner.  Each Covered Person shall use his best efforts within his area of expertise to assure that Fund reports reveal, rather than conceal, the relevant Fund’s financial condition.

Each Covered Person shall seek to obtain additional resources if he believes that available resources are inadequate to enable the Funds to provide full, fair and accurate financial information and other disclosure to regulators and Fund shareholders.

Each Covered Person shall inquire of other Fund officers and service providers, as appropriate, to assure that information provided is accurate and complete and presented in an understandable format using comprehensible language.

4

Each Covered Person shall diligently perform his services to the Funds, so that information can be gathered and assessed early enough to facilitate timely filings and issuance of reports and required certifications.

Promotion of Compliance with Applicable Government Laws, Rules and Regulations

Each Covered Person shall become and remain knowledgeable concerning the laws and regulations relating to the Funds and their operations and shall act with competence and due care in serving as an officer of the Funds.  Each Covered Person with specific responsibility for financial statement disclosure will become and remain knowledgeable concerning relevant auditing standards, generally accepted accounting principles, FASB pronouncements and other accounting and tax literature and developments.

Each Covered Person shall devote sufficient time to fulfilling his responsibilities to the Funds, recognizing that he will devote substantial time to providing services to other Credit Suisse clients and will perform other activities as an employee of Credit Suisse.

Each Covered Person shall cooperate with a Fund’s independent auditors, regulatory agencies and internal auditors in their review or inspection of the Fund and its operations.

No Covered Person shall knowingly violate any law or regulation relating to the Funds or their operations or seek to illegally circumvent any such law or regulation.

No Covered Person shall engage in any conduct involving dishonesty, fraud, deceit or misrepresentation involving the Funds or their operations.

5

Promoting Prompt Internal Reporting of Violations

Each Covered Person shall promptly report his own violations of this Code and violations by other Covered Persons of which he is aware to the Chairman of the relevant Fund’s Audit Committee.

Any requests for a waiver from or an amendment to this Code shall be made to the Chairman of the relevant Fund’s Audit Committee.  All waivers and amendments shall be disclosed as required by law.

Sanctions

Failure to comply with this Code will subject the violator to appropriate sanctions, which will vary based on the nature and severity of the violation.  Such sanctions may include censure, suspension or termination of position as an officer of the Fund.  Sanctions shall be imposed by the relevant Fund’s Audit Committee, subject to review by the entire Board of Directors/Trustees of the Fund.

Each Covered Person shall be required to certify annually whether he has complied with this Code.

No Rights Created

This Code of Ethics is a statement of certain fundamental principles, policies and procedures that govern the Funds’ senior officers in the conduct of the Funds’ business.  It is not intended to and does not create any rights in any employee, investor, supplier, competitor, shareholder or any other person or entity.

6

Recordkeeping

The Funds will maintain and preserve for a period of not less than six (6) years from the date such action is taken, the first two (2) years in an easily accessible place, a copy of the information or materials supplied to the Board (1) that provided the basis for any amendment or waiver to this Code and (2) relating to any violation of the Code and sanctions imposed for such violation, together with a written record of the approval or action taken by the relevant Board.

Amendments

The Directors/Trustees will make and approve such changes to this Code of Ethics as they deem necessary or appropriate to effectuate the purposes of this Code.
