Credit Suisse High Yield Bond Fund

Semiannual Investment Adviser's Report

April 30, 2013 (unaudited)

June 28, 2013

Dear Shareholder:

We are pleased to present this Semiannual Report covering the activities of the Credit Suisse High Yield Bond Fund for the six month period ended April 30, 2013.

Performance Summary

11/01/12 04/30/13

Fund & Benchmark
Total Return (based on NAV) 1	10.83 %
Total Return (based on market value) 1	11.57 %
BofA Merrill Lynch US High Yield Master II Constrained Index 2	7.26 %

Market Review: Fundamentals continue to improve

The six month period ended April 30, 2013 was a positive one for credit markets. The BofA Merrill Lynch High Yield Master II Constrained Index, the Fund's benchmark, returned 7.26%. High yield spreads tightened versus the Treasury market to finish April at 458 basis points as opposed to 574 basis points in October 2012. Yields ended the period near their all-time lows at 5.26%.

From a quality point-of view, CCC-rated securities outperformed, returning 10.9%. BB and B-rated securities also posted positive gains to end the period with returns of 5.7% and 7.3%, respectively. Monoline insurance, integrated energy and multiline insurance sectors led the Index, while hotels, beverage and printing and publishing were the biggest detractors from overall performance during the period.

High yield default rates have experienced a decrease during the period and the trailing 12-month par-weighted default rate, as measured by JP Morgan, fell to 0.99% in April 2013. This compares to a rate of 1.77% six months ago and is well below the historical average of 4.0%.

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 6.2% through April, down from 10.7% six months ago. Additionally, according to JP Morgan, new issue volume for the period was $215bn surpassing the previous period volume of $181bn.

High-yield mutual funds saw net negative flows during the period, for a total outflow of approximately $2.0bn as reported by Lipper FMI. The majority of the outflows occurred in November-December 2012 and February 2013. Conversely, the asset class saw net inflows in January, March and April 2013.

Strategic Review and Outlook: Cautiously optimistic going forward

For the six month period ended April 30, 2013, the Fund outperformed the benchmark on both an NAV and market value basis. Positive security selection in the energy and exploration, building and construction and chemicals sectors contributed positively to returns. Additionally, positioning in B-rated securities as well as an underweight to BB-rated securities also contributed to returns. In contrast, the Fund's exposure to the electric-generation sector detracted from returns.

Fund exposures continue to emphasize the B-rated bonds that exhibit the most compelling risk-return profiles. The Fund has avoided the most interest rate sensitive, lower coupon securities and have maintained exposure to shorter duration bonds. Additionally, the Fund is underweight the most levered and aggressive CC-rated components of the Index. These components typically exhibit the most volatility in a heightened macro risk environment and we do not believe current valuations adequately compensate investors on a relative basis. Lastly,

Credit Suisse High Yield Bond Fund

Semiannual Investment Adviser's Report (continued)

April 30, 2013 (unaudited)

we continue to focus the portfolio on lower beta securities whose valuations are not as exposed to market fluctuations.

Fundamentals have remained strong in the high-yield market, as balance sheet management remains a focus for high yield issuers. In turn, this has supported continued below-average default rates. In fact, defaults are expected to remain below average for 2013. Although inflows into high-yield mutual funds have been more mixed versus the record pace of 2012, investors have demonstrated continued confidence in credit markets. As markets have rallied, we believe valuations in many cases are capped as a significant portion of bonds in the high yield market are already trading at or above their call prices. Against this backdrop, we see pockets of opportunities within the high yield asset class, although we remain cautious given valuations.

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 April 30, 2013; these views and Fund holdings may have changed subsequent to these dates. Nothing in this document is a recommendation to purchase or sell securities.

Market Value	19.59 %	15.11 %	12.03 %	8.96 %

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. Total returns for periods less than one year are not annualized.

Credit Suisse High Yield Bond Fund

Notes to Financial Statements

April 30, 2013 (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 (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. 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. 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. Forward currency contracts are valued at the prevailing forward exchange rate of the underlying currencies and are generally categorized as Level 2. Time deposits are valued at cost 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 April 30, 2013, the Fund held 0.10% 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 $3,041,641 and fair value of $301,615. 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 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 April 30, 2013 in valuing the Fund's investments carried at value:

	Level 1	Level 2			Total
Investments in Securities
Corporate Bonds	$	$ 360,528,731	$	199	$ 360,528,930

Other financial instruments include forwards foreign currency contracts.

The following is a reconciliation of investments as of April 30, 2013 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.

Credit Suisse High Yield Bond Fund

Notes to Financial Statements (continued)

April 30, 2013 (unaudited)

The Fund adopted FASB amendments to authoritative guidance which require the Fund to disclose details of transfers in and out of Level 1 and Level 2 measurements and Level 2 and Level 3 measurements and the reasons for the transfers. For the six months ended April 30, 2013, there were no significant transfers in and out of Level 1 and Level 2, but there was $177,463 transferred in from Level 2 to Level 1. All transfers are assumed to occur at the end of the reporting period.

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. For the six months ended April 30, 2013, the Fund's derivatives did not qualify for hedge accounting as they are held at fair value.

Fair Values of Derivative Instruments as of April 30, 2013

	Asset Derivatives — Balance Sheet Location	Fair Value	Liability Derivatives — Balance Sheet Location	Fair Value
Currency Contracts	Unrealized appreciation on forward currency contracts	$ 19,376	Unrealized depreciation on forward currency contracts	$ 89,786

Effect of Derivative Instruments on the Statement of Operations

	Location	Realized Gain/Loss	Location	Unrealized Appreciation/ (Depreciation)
Currency Contracts	Net realized gain from foreign currency transactions	$ 341,094	Net change in unrealized appreciation (depreciation) from foreign currency transactions	$ (367,011	)

The notional amount of forward foreign currency contracts at period ended 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 7.31% 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.

Credit Suisse High Yield Bond Fund

Notes to Financial Statements (continued)

April 30, 2013 (unaudited)

E) DIVIDENDS AND DISTRIBUTIONS TO SHAREHOLDERS The Fund declares and pays dividends on a monthly basis and records them on ex-date. 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 ("RIC") under the Internal Revenue Code of 1986, as amended (the "Code"), and to make the requisite distributions to its shareholders, which will be sufficient to relieve it from federal income and excise taxes.

In order to qualify as a RIC under the Code, the Fund must meet certain requirements regarding the source of its income, the diversification of its assets and the distribution of its income. One of these requirements is that the Fund derive at least 90% of its gross income for each taxable year from dividends, interest, payments with respect to certain securities loans, gains from the sale or other disposition of stock, securities or foreign currencies, other income derived with respect to its business of investing in such stock, securities or currencies or net income derived from interests in certain publicly traded partnerships ("Qualifying Income").

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, including domestic and foreign currencies. 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 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 April 30, 2013, the Fund had the following open forward foreign currency contracts:

Forward Foreign Forward Foreign Currency to be Purchased (Local) — GBP	50,000	Currency to be Sold (Local) — USD	76,285	Expiration Date — 07/15/13	Counterparties — Morgan Stanley	Value on Settlement Date — $ 76,285	$	77,785	$	1,500
USD	24,750,000	EUR	18,750,000	07/15/13	Morgan Stanley	(24,750,000	)	(24,732,124	)	17,876

									$	(70,410	)

Currency Abbreviations:

EUR = Euro

GBP = British Pound

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 six months ended April 30, 2013, total earnings from the Fund's investment in cash collateral received in connection with securities lending arrangements was $42,918, of which $0 was rebated to borrowers (brokers). The Fund retained $36,481 in income from the cash collateral investment, and SSB, as lending agent, was paid $6,437. 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.

April 30, 2013 (unaudited)

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) NEW ACCOUNTING PRONOUNCEMENTS In December 2011, the Financial Accounting Standards Board issued Accounting Standards Update ("ASU") No. 2011-11, Balance Sheet (Topic 210): Disclosures about Offsetting Assets and Liabilities. The amendments in the ASU enhance disclosures about offsetting of financial assets and liabilities to enable investors to understand the effect of these arrangements on a fund's financial position. The ASU is effective for interim and annual reporting periods beginning on or after January 1, 2013. The Fund believes the adoption of this ASU will not have a material impact on its financial statements.

N) SUBSEQUENT EVENTS In preparing the financial statements as of April 30, 2013, management considered the impact of subsequent events for potential recognition or disclosure in these financial statements through the date of release of this report. No such events requiring recognition or disclosure were identified through the date of the release of this report.

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, 2011, Credit Suisse has 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 six months ended April 30, 2013, investment advisory fees earned and voluntarily waived were $1,791,258 and $210,753, respectively. Fee waivers and expense reimbursements are voluntary and may be discontinued by Credit Suisse at any time.

SSB serves as Accounting and Administrative Agent to 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, 2013, administrative services fees earned by SSB (including out-of-pocket expenses) with respect to the Fund were $35,365.

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 six months ended April 30, 2013, 9,032 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 six months ended April 30, 2013, Merrill was paid $38,778 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"). Effective December 7, 2012, the Fund may borrow the least of: a) $170,000,000; 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 April 30, 2013, the Fund

Credit Suisse High Yield Bond Fund

Notes to Financial Statements (continued)

April 30, 2013 (unaudited)

had loans outstanding under the Agreement of $116,000,000. During the six months ended April 30, 2013, the Fund had borrowings under the Agreement as follows:

Average Daily Loan Balance		Maximum Daily Loan Outstanding
$ 107,243,094	1.092 %	$ 116,000,000

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 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.

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 the Fund has 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, 2013, purchases and sales of investment securities (excluding short-term investments) were $155,821,488 and $143,141,237, respectively.

At April 30, 2013, the cost of investments (excluding foreign currency related transactions) and net unrealized appreciation (depreciation) for income tax purposes were as follows:

Cost of Investments	$
Unrealized appreciation	$ 25,612,104
Unrealized depreciation	(13,267,676	)
Net unrealized appreciation (depreciation)	$ 12,344,428

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:

Shares issued through the trustees compensation plan	9,032	18,468
Shares issued through at-the-market offerings	5,422,876	16,058,741
Shares issued through reinvestment of dividends	141,340	274,683
Net increase	5,573,248	16,351,892

Note 7. Shelf Offering

On September 14, 2012, the Fund filed a "shelf" registration statement with the SEC, which permits the Fund to issue up to $93,778,401 in shares of beneficial interest through one or more public offerings. Under the shelf registration statement and a previously effective shelf registration statement, the Fund sold and may sell the Fund's shares of beneficial interest in one or more at-the-market offerings when market conditions are considered favorable. Such shares were and would only be issued when the premium to net asset value is greater than the costs associated with the transaction. Any proceeds raised are used for investment purposes. As of April 30, 2013, the Fund had offered and sold 5,422,876 shares of beneficial interest in at-the-market offerings pursuant to sales agreements, resulting in proceeds (net of all fees and commissions) of $17,463,270.

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.

Credit Suisse High Yield Bond Fund

Board Approval of Investment Advisory Agreement (unaudited)

In approving the renewal of the current Advisory Agreement, the Board of Trustees (the "Board") of Credit Suisse High Yield Bond Fund (the "Fund"), including all of the Trustees who are not "interested persons" of the Fund as defined in the Investment Company Act of 1940 (the "Independent Trustees"), at a meeting held on November 12 and 13, 2012 considered the following factors:

Investment Advisory Fee Rates and Expenses

The Board reviewed and considered the contractual investment advisory fee rate of 1.00% of the average weekly value of the Fund's total assets minus the sum of accrued liabilities (other than aggregate indebtedness constituting leverage) (the "Managed Assets") less than or equal to $250 million and 0.75% of the Managed Assets greater than $250 million (the "Gross Advisory Fee") in light of the extent and quality of the advisory services provided by Credit Suisse Asset Management, LCC ("Credit Suisse"). The Board also reviewed and considered the voluntary fee waivers currently in place for the Fund and considered the actual fee rate of 0.90% paid by the Fund after taking waivers and breakpoints into account (the "Net Advisory Fee") as of September 30, 2012. The Board noted that Credit Suisse, at the Board's request, had revised the voluntary waiver as of January 1, 2011 so that it was voluntarily waiving 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. Although the voluntary fee waivers could be discontinued at any time, Credit Suisse advised the Board that it would not consider removing the waiver until the Board next considered the renewal of the Advisory Agreement.

Additionally, the Board received and considered information comparing the Gross Advisory Fee, the combined Gross Advisory Fee and gross administration fee (together, the "Gross Management Fee"), the Gross Management Fee less waivers and/or reimbursements (the "Net Management Fee"), and the Fund's net total expenses with those of funds in the relevant expense group ("Expense Group") provided by an independent provider of investment company data. The Board also received and considered information comparing the Fund's net total expenses and Net Management Fee to the funds in the relevant Morningstar category ("Morningstar Category"). The Board was provided with a description of the methodology used to arrive at the funds included in the Expense Group and the Morningstar Category.

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

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

Fund Performance

The Board received and considered performance results of the Fund over time, along with comparisons both to the Expense Group and the Morningstar Category for the Fund.

Board Approval of Investment Advisory Agreement (unaudited) (continued)

Credit Suisse Profitability

The Board received and considered a profitability analysis of Credit Suisse based on the fees payable under the Advisory Agreement for the Fund, including any fee waivers, as well as other relationships between the Fund on the one hand and Credit Suisse affiliates on the other. The Board also considered Credit Suisse's methodology for allocating costs to the Fund, recognizing that cost allocation methodologies are inherently subjective.

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. Accordingly, the Board considered whether the breakpoints in the Fund's advisory fee structure were appropriate and reasonable taking into consideration economies of scale or other efficiencies that might accrue from increases in the Fund's asset levels.

Other Benefits to Credit Suisse

The Board considered other benefits received by Credit Suisse and its affiliates as a result of their relationship with the Fund. Such benefits include, among others, benefits potentially derived from an increase in Credit Suisse's businesses as a result of its relationship with the Fund (such as the ability to market to shareholders other financial products offered by Credit Suisse and its affiliates).

The Board considered the standards applied in seeking best execution and reviewed Credit Suisse's method for allocating portfolio investment opportunities among its advisory clients.

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, detailed fund performance reports and Credit Suisse's compliance procedures.

Conclusions

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

• Although the Gross Advisory Fee, Gross Management Fee and Net Management Fee were above the median of the Expense Group, the fees were reasonable, recognizing that the net total expenses were just above the median of the Expense Group. In addition, Credit Suisse noted that the recent decrease in other Fund expenses was expected to further lower the Fund's total expenses over the upcoming year.

• The Fund's performance was below the median of the Expense Group for the five- and ten- year periods ended September 30, 2012, but was above the median for the year-to-date, one- and three-year periods. The Fund also outperformed its Morningstar Category average for the year-to-date, one-, and three- year periods ended September 30, 2012, but underperformed for the five- and ten-year periods ended September 30, 2012.

• The Board was satisfied with the nature, extent and quality of the investment advisory services provided to the Fund by Credit Suisse and that, based on dialogue with management and counsel, the services provided

Credit Suisse High Yield Bond Fund

by Credit Suisse under the Advisory Agreement are typical of, and consistent with, those provided to similar mutual funds by other investment advisers.

• In light of the costs of providing investment management and other services to the Fund and Credit Suisse's ongoing commitment to the Fund and willingness to waive fees, Credit Suisse's profitability based on fees payable under the Advisory Agreement, as well as other ancillary benefits that Credit Suisse and its affiliates received, were considered reasonable.

• In light of the information received and considered by the Board, the Fund's current fee structure was considered reasonable.

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

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.
