Credit Suisse High Yield Bond Fund

Semiannual Investment Adviser’s Report

April 30, 2014 (unaudited)

June 23, 2014

Dear Shareholder:

We are pleased to present this semiannual Report covering the activities of the Credit Suisse High Yield Bond Fund (the “Fund”), for the six-months ended April 30, 2014.

Performance Summary

11/01/13 – 04/30/14

Fund & Benchmark	Performance
Total Return (based on NAV)1		6.12	%
Total Return (based on market value)1		6.44	%
BofA Merrill Lynch High Yield Master II Constrained Index2		4.76	%

Market Review: A positive period

The six-months ended April 30, 2014, was a positive period for the high yield market, with the BofA Merrill Lynch High Yield Master II Constrained Index, the Fund’s benchmark, returning 4.76%. High yield levels have been supported by continued inflows into the asset class as well as Treasury yields, as the 10-year U.S. Treasury, which had widened to 3.03% by December 31, 2013, tightened to 2.65% by the end of April.

Other notable headlines in the high yield market include the highly anticipated default of Energy Futures (TXU), a Texas based utility company, that had been telegraphed for months. Despite the headlines, expectations for default rates continue to remain below historical averages given a constructive outlook on fundamentals. High yield spreads tightened by 57 basis points versus Treasuries to finish April at +388 basis points. The yield-to-worst finished the month close to unchanged at 5.22%, compared to 5.66% at the end of October.

For the market, most rating classes produced positive returns with CC-rated, returning 10.42%, leading the pack. CCC-rated and BB-rated bonds followed closely, returning 5.64% and 4.67%, respectively. B-rated bonds underperformed, returning 4.38%. The best performing sectors for the period were department stores, insurance and tobacco, returning 9.6%, 9.5% and 8.4%, respectively. Sector laggards included specialty retail, 2.5%, and metals/mining, with 2.8%.

The par-weighted, high yield bond default rate, as reported by JPMorgan, increased to 2.15% in April following the default of Energy Futures (TXU). Although the default was one of the largest on record, the issuer-weighted default rate continues to remain at a benign 1.75%. Absent the expected Energy Futures (TXU) default, our default forecast remains sanguine and below long-term averages for the next 1-2 years. The U.S. high yield distress ratio, which measures the proportion of bonds trading at spreads of more than 1,000 basis points over Treasuries, improved slightly, going from 5.7% in October to 5.0% in April, according to Bank of America.

As discussed previously, technicals in the high yield market have supported overall market returns. On a year-to-date basis, high yield mutual funds reported inflows totaling $4.2 billion. From a supply perspective, new issue volumes totaled $130 billion year-to-date — similar to the same period for 2013.

Portfolio Review and Outlook: Looking for pockets of opportunity

For the six months ended April 30, 2014, the Fund outperformed the BofA Merrill Lynch High Yield Master II Constrained Index. Positive security selection positions in B and BB rated debt contributed to returns. In addition, security selection to the specialty retail, oil services and support services sectors, as well as an underweight to consumer/commercial/lease financing, contributed positively to relative returns. In contrast, an underweight to banking and security selection within the auto parts sector detracted from performance.

The Fund’s investment strategy continues to focus on shorter duration bonds and the Fund has also taken advantage of recent interest rate volatility by taking profits in bonds with 8-10 year maturities that have traded up along with the Treasury market. Many of these names were added in the second and third quarter of 2013, when high yield markets were weaker.

Semiannual Investment Adviser’s Report (continued)

In addition, the Fund’s trading activity in 2014 has been focused on purchases from the new issue calendar or with 5-8 year maturity. We continued to reduce the Fund’s positions in the very short end of the curve in names that were callable in the next year or two and whose valuations were no longer compelling. The Fund also remained invested in lower beta securities whose valuations were less exposed to market fluctuations and emphasized B-rated bonds that exhibit the most compelling risk-return profiles.

Looking forward, although high yield markets have rallied through the beginning of this year, we believe valuations in many cases are capped as a portion of bonds in the high yield market are already trading at or above their call prices. Against this backdrop, we will remain selective and look for pockets of opportunities within the high yield asset class.

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.

The Fund is non-diversified, which means it may invest a greater proportion of its assets in securities of a smaller number of issuers than a diversified fund and may therefore be subject to greater volatility.

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, 2014; these views and Fund holdings may have changed subsequent to these dates. Nothing in this document is a recommendation to purchase or sell securities.

An index does not have transaction costs; investors cannot invest directly in an index.

Credit Suisse may waive 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  This amount represents less than $0.01 per share.

³  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

April 30, 2014 (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

The following is a summary of significant accounting policies followed by the Fund in the preparation of its financial statements. The policies are in accordance with accounting principles generally accepted in the United States of America (“GAAP”). The preparation of financial statements requires management to make estimates and assumptions that affect the reported amounts and disclosures in the financial statements. Actual results could differ from those estimates.

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. The valuations for fixed income securities (which may include, but are not limited to, corporate, government, municipal, mortgage-backed, collateralized mortgage obligations and asset-backed securities) and certain derivative instruments are typically the prices supplied by independent third party pricing services, which may use market prices or broker/dealer quotations or a variety of valuation techniques and methodologies. The independent third party pricing services use inputs that are observable such as issuer details, interest rates, yield curves, prepayment speeds, credit risks/spreads, default rates and quoted prices for similar securities. Short-term fixed income securities that will mature in 60 days or less may be valued at amortized cost. Structured note agreements are valued in accordance with a dealer-supplied valuation based on changes in the value of the underlying index. Forward contracts are valued at the London closing spot rates and the London closing forward point rates on a daily basis. The currency forward contract pricing model derives the differential in point rates to the expiration date of the forward and calculates its present value. The forward contracts are valued at the net of the present value and the spot rate and are generally categorized as Level 2. Equity securities for which market quotations are available are valued at the last reported sales price or official closing price on the primary market or exchange on which they trade. The Fund may utilize a service provided by an independent third party which has been approved by the Board of Trustees (the “Board”) to fair value certain securities. When fair value pricing is employed, the prices of securities used by the Fund to calculate its net asset value may differ from quoted or published prices for the same securities. If independent third party pricing services are unable to supply prices for a portfolio investment, or if the prices supplied are deemed by the investment adviser to be unreliable, the market price may be determined by the investment adviser using quotations from one or more broker/dealers or at the transaction price if the security has recently been purchased and no value has yet been obtained from a pricing service or pricing broker. When reliable prices are not readily available, such as when the value of a security has been significantly affected by events after the close of the exchange or market on which the security is principally traded, but before the Fund calculates its net asset value, the Fund values these securities as determined in accordance with procedures approved and established by the Fund’s Board.

The Fund uses valuation techniques to measure fair value that are consistent with the market approach and/or income approach, depending on the type of security and the particular circumstance. The market approach uses prices and other relevant information generated by market transactions involving identical or comparable securities. The income approach uses valuation techniques to discount estimated future cash flows to present value.

Notes to Financial Statements (continued)

April 30, 2014 (unaudited)

GAAP established a disclosure hierarchy that categorizes the inputs to valuation techniques used to value assets and liabilities at measurement date. These inputs are 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 methodologies used to value 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, 2014 in valuing the Fund’s assets and liabilities carried at fair value:

	Level 1		Level 2			Level 3		Total
Investments in Securities
Corporate Bonds	$	—	$	367,922,200		$	5,989	$	367,928,189

* Other financial instruments include unrealized appreciation (depreciation) on forward foreign currency contracts.

The following is a reconciliation of investments as of April 30, 2014 in which significant unobservable inputs were used in determining value. Transfers in or out of Level 3 represent the end of the period value of any security or instrument where a change in the level has occurred from the beginning to the end of the period.

	Corporate Bonds			Asset Backed Securities			Common Stocks		Total

The Fund follows Financial Accounting Standards Board (“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, 2014, there were no transfers in and out of Level 1, Level 2 and Level 3.

B) DERIVATIVE INSTRUMENTS AND HEDGING ACTIVITIES — The Fund adopted amendments to authoritative guidance on disclosures about derivative instruments and hedging activities which require that a 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, 2014, 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, 2014

	Asset Derivatives			Liability Derivatives
	Balance Sheet Location	Fair Value		Balance Sheet Location	Fair Value
Currency Contracts	Unrealized appreciation on forward currency contracts	$	11,880	Unrealized depreciation on forward currency contracts	$	147,513

Effect of Derivative Instruments on the Statement of Operations

	Location	Realized Gain (Loss)			Location	Net Unrealized Appreciation (Depreciation)
Currency Contracts	Net realized loss from foreign currency transactions	$	(846,359	)	Net change in unrealized appreciation (depreciation) from foreign currency translations	$	38,024

The notional amount of forward foreign currency contracts at the period ended April 30, 2014 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 9.5% of net assets of the Fund.

The Fund is a party to International Swap and Derivatives Association, Inc. (“ISDA”) Master Agreements (“Master Agreements”) with certain counterparties that govern over-the-counter derivative (including Total Return, Credit Default and Interest Rate Swaps) and foreign exchange contracts entered into by the Fund. The Master Agreements may contain provisions regarding, among other things, the parties’ general obligations, representations, agreements, collateral requirements, events of default and early termination. Termination events applicable to the Fund may occur upon a decline in the Fund’s net assets below a specified threshold over a certain period of time.

The following table presents by counterparty the Fund’s derivative assets net of related collateral held by the Fund at April 30, 2014:

Counterparty	Gross Amounts of Assets Presented in the Statement of Assets and Liabilities(a)		Financial Instruments and Derivatives Available for Offset			Non-Cash Collateral Received		Cash Collateral Received		Net Amount of Derivative Assets

The following table presents by counterparty the Fund’s derivative liabilities net of related collateral pledged by the Fund at April 30, 2014:

Counterparty	Gross Amounts of Liabilities Presented in the Statement of Assets and Liabilities(a)		Financial Instruments and Derivatives Available for Offset			Non-Cash Collateral Pledged		Cash Collateral Pledged		Net Amount of Derivative Liabilities
Morgan Stanley	$	147,513	$	(11,880	)	$	—	$	—	$	135,633

^(a)  Forward foreign currency exchange contracts are included.

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/EXPENSE — Security transactions are accounted for on a trade date basis. Interest income/expense is recorded on the accrual basis. The Fund amortizes premiums and accretes discounts using the effective interest method. Dividend income/expense is 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.

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

22

Credit Suisse High Yield Bond Fund

Notes to Financial Statements (continued)

April 30, 2014 (unaudited)

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) SHORT-TERM INVESTMENTS — The Fund, together with other funds/portfolios advised by 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.

H) 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.

I) 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, 2014, the Fund had the following open forward foreign currency contracts:

Forward Foreign Currency to be Purchased (Local)		Forward Foreign Currency to be Sold (Local)		Expiration Date		Counterparty	Value on Settlement Date			Current Value			Net Unrealized Appreciation (Depreciation)
EUR	1,700,000	USD	2,344,873		07/15/14	Morgan Stanley	$	2,344,873		$	2,356,753		$	11,880

J) 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. As of April 30, 2014, the Fund had investment securities on loan with a fair value of $9,304,506 and a related liability of $9,511,790 for collateral received on securities loaned, both of which are presented gross on the Statement of Assets and Liabilities. The carrying value of the collateral for securities loaned approximates fair value which would have been considered level 2 under the fair value hierarchy if the collateral for securities loaned were carried at fair value. For the six months ended April 30, 2014, the value of the related collateral exceeded the value of the securities loaned.

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, 2014, total earnings from the Fund’s investment in cash collateral received in connection with securities lending arrangements was $35,009, of which $0 was rebated to borrowers (brokers). The Fund retained $29,727 in income from the cash collateral investment, and SSB, as lending agent, was paid $5,282. Securities lending income is accrued as earned.

K) 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.

L) SUBSEQUENT EVENTS — In preparing the financial statements as of April 30, 2014, 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, 2014, investment advisory fees earned and voluntarily waived were $1,973,725 and $210,753, respectively. Fee waivers and expense reimbursements are voluntary and may be discontinued by Credit Suisse at any time.

24

Credit Suisse High Yield Bond Fund

Notes to Financial Statements (continued)

April 30, 2014 (unaudited)

SSB serves as Accounting and Administrative Agent for the Fund. For its administrative services, SSB receives a fee, exclusive of out-of-pocket expenses, calculated in total for all the Credit Suisse funds/portfolios co-administered by SSB and allocated based upon the relative average net assets of each fund/portfolio, subject to an annual minimum fee. For the six months ended April 30, 2014, administrative services fees earned by SSB (including out-of-pocket expenses) with respect to the Fund were $38,346.

The Independent Trustees receive fifty percent (50%) of their annual retainer in the form of shares. During the year ended October 31, 2013 and the six months ended April 30, 2014, 18,006 shares and 10,159 shares were issued through the Trustees’ compensation plan, respectively. 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, 2014, Merrill was paid $13,829 for its services by the Fund. This amount was included in the printing fees presented on the Statement of Operations.

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 6, 2013, 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. Under the terms of the SSB Agreement, the Fund pays a commitment on the unused amount. In addition, the Fund pays interest on borrowings at LIBOR plus a spread. At April 30, 2014, the Fund had loans outstanding under the Agreement of $148,000,000. During the six months ended April 30, 2014, the Fund had borrowings under the Agreement as follows:

Average Daily Loan Balance	Weighted Average Interest Rate %			Maximum Daily Loan Outstanding		Interest Rate
$140,936,464		1.139	%	$	148,000,000	$	712,454

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

Certain types of borrowings by the Fund may result in the Fund being subject to covenants in credit agreements, including those relating to asset coverage and portfolio composition requirements. The Fund’s

25

Credit Suisse High Yield Bond Fund

Notes to Financial Statements (continued)

April 30, 2014 (unaudited)

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, 2014, purchases and sales of investment securities (excluding short-term investments) were $136,204,057 and $143,510,394, respectively.

Note 6. Fund Shares

Shares may be offered at prices and terms to be set forth in one or more supplements to the Fund’s prospectus included in the shelf registration statement. On April 14, 2014, the Fund filed a prospectus supplement relating to an at-the-market offering of the Fund’s shares of common stock.

Note 8. Contingencies

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

Note 9. Other Matters

On May 19, 2014, the U.S. Department of Justice (the “Department of Justice”) filed a one-count criminal information (the “Information”) in the District Court for the Eastern District of Virginia charging Credit Suisse AG (“CSAG”) with conspiracy to commit tax fraud related to accounts CSAG established for cross-border clients. The Department of Justice and CSAG entered into a plea agreement (the “Plea Agreement”) settling the action pursuant to which CSAG pleaded guilty to the charge set out in the Information.

The Plea Agreement requires CSAG to pay over $1.8 billion to the U.S. government, including the U.S. Internal Revenue Service. The Plea Agreement also requires CSAG to lawfully undertake certain remedial actions to address the conduct described in the Plea Agreement.

CSAG has entered into other settlements relating to the conduct set out in the Plea Agreement. CSAG has entered into a Consent Order with the Federal Reserve Board (the “Federal Reserve”) to resolve certain findings by the Federal Reserve, including that the activities of CSAG regarding opening of foreign accounts for U.S. taxpayers, provision of investment services to U.S. clients, and operation of CSAG’s New York representative office prior to 2009 lacked adequate enterprise-wide risk management and compliance policies and procedures sufficient to ensure that all of its activities comply with U.S. laws and regulations. In addition, CSAG has entered into a Consent Order with the New York State Department of Financial Services (the “DFS”) to resolve the DFS’s investigation into the conduct described in the Plea Agreement. The settlement with the Federal Reserve requires CSAG to pay $100 million to the Federal Reserve, and the settlement with the DFS requires CSAG to pay $715 million to the DFS.

These settlements follow a settlement by Credit Suisse Group AG (“CS Group”), the parent company of CSAG, with the Securities and Exchange Commission (the “Commission”) on February 21, 2014 to resolve an investigation by the Commission into solicitation and provision of broker-dealer and investment advisory services to certain U.S. cross-border clients by CS Group while not registered with the Commission as a broker-dealer or investment adviser. As part of the settlement, CS Group retained an independent consultant to evaluate its policies and procedures and examine its broker-dealer and investment adviser activities to fully verify that the business that was the subject of the Commission investigation has been completely exited. CS Group also agreed to pay $196,511,014, which includes $82,170,990 in disgorgement, $64,340,024 in interest and a $50,000,000 penalty.

CSAG is the indirect parent company of Credit Suisse and CSSU. Neither Credit Suisse, CSSU nor the Fund was named in the Plea Agreement (as defined below) or other settlements relating to the conduct set out in the Plea Agreement. The conduct set out in the Plea Agreement did not involve the Fund, Credit Suisse or CSSU with respect to its investment adviser and distribution activities relating to the Fund.

Credit Suisse, CSSU and certain of their affiliates have received a permanent exemptive order from the Commission to permit them to continue serving as investment advisers and principal underwriters for U.S.-registered investment companies, such as the Fund. Due to a provision in the law governing the operation of U.S.-registered investment companies, they would otherwise have become ineligible to perform these activities as a result of the plea in the Plea Agreement. The permanent exemptive order permits Credit Suisse and CSSU to continue to provide services to the Fund, so long as, among other things, no current or former employee of CSAG or any affiliate of CSAG who previously has been or who subsequently may be identified by CSAG or any U.S. or non-U.S. regulatory or enforcement agencies as having been responsible for the conduct described in the Plea

Agreement will be employed by Credit Suisse and certain of its affiliates. Credit Suisse and CSSU have informed the Fund that, Credit Suisse and CSSU believe the Settlements will not have any material impact on the Fund or on the ability of Credit Suisse or CSSU to perform services for the Fund.

Credit Suisse High Yield Bond Fund

Board Approval of Advisory Agreement (unaudited)

In approving the renewal of the current Advisory Agreement for the Fund, the Board, 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 11 and 12, 2013 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, LLC (“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 0.85% paid by the Fund after taking waivers and breakpoints into account (the “Net Advisory Fee”) as of September 30, 2013. 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. The Board acknowledged that voluntary fee waivers could be discontinued at any time.

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 Part 2 – Disclosure Brochure and Brochure Supplement. 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 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 renewal of the Advisory Agreement and the investment advisory fee under such agreement, the Board concluded that:

• Although the Gross Advisory Fee, the Gross Management Fee and the Net Management Fee and the net total expenses were all above the median of the Expense Group, the fees were reasonable. The Trustees noted that the Net Advisory Fee for the year ended September 30, 2013 was lower than for the year ended September 30, 2012.

• The Fund’s performance was below the median of the Expense Group for the ten-year period ended September 30, 2013, but was above the median for the year-to-date, one-, three- and five-year periods. The Fund also outperformed its Morningstar Category average for the year-to-date, one-, three- and five-year periods ended September 30, 2013, but was in the third quartile for the ten-year period ended September 30, 2013.

31

Credit Suisse High Yield Bond Fund

Board Approval of Advisory Agreement (unaudited) (continued)

• 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 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 renewal of 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.
