Credit Suisse High Yield Bond Fund

Semiannual Investment Adviser’s Report

April 30, 2017 (unaudited)

May 26, 2017

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-month period ended April 30, 2017.

Performance Summary

11/1/2016 – 4/30/2017

Fund & Benchmark	Performance
Total Return (based on NAV)1		12.07	%
Total Return (based on market value)1		19.47	%
BofA Merrill Lynch U.S. High Yield Master II Constrained Index2		5.92	%

Market Review: High yields enjoy positive returns

The six-month period ended April 30, 2017 was a positive one for the high yield asset class, with the BofA Merrill Lynch U.S. High Yield Master II Constrained Index (the “Benchmark”), the Fund’s benchmark, returning 5.92%. The high yield asset class enjoyed a substantial rally in the last year. In fact, yields are now hovering at multi-year lows amidst an environment of strong equity performance, solid economic data, stable earnings, low U.S. Treasury yields and limited net new issuance.

Yields ended the period at 5.65%, 68 basis points tighter versus October 31, 2016, and 54 basis points tighter than year-end 2016. Spreads ended the period at +395 basis points, as compared to +503 basis points on October 31, 2016 and +439 basis points at year-end.

For the period, CCC-rated bonds outperformed the Benchmark, returning 10.14%, while BB-rated and B-rated bonds underperformed at 3.87% and 5.74%, respectively.

From an industry perspective, telecom satellite (+23.1%), transport infrastructure/services (+17.0%), oil field equipment & services (+12.7%), oil refining (+9.5%) and telecom-wireline (+9.0%) were the top five performing sectors, while department stores (-7.1%) and pharmaceuticals (-0.5%) were the lowest performing sectors, with the only negative returns for the period.

Default activity, as measured by JPMorgan, decreased to 1.39% in April, down from 3.57% at year-end 2016 and the lowest rate since March 2014 (0.61%). JPMorgan lowered its 2017 default rate forecast by 50 basis points (to 2.0%), while keeping its 2018 default rate forecast steady at 3.0%.

Calendar year-to-date, high-yield bond mutual funds have reported $7.2 billion in outflows, compared with $12.0 billion of inflows over the same period in 2016. The outflows mostly occurred in March, as weakness in oil and a rise in U.S. Treasury yields put temporary pressure on the high yield market. Once oil somewhat stabilized, outflows reversed and high yield mutual funds experienced positive inflows of $1 billion in April.

New issuance for the period was down slightly when compared with the previous six-month period, at $154 billion versus $167 billion.

Strategic Review and Outlook: Maintaining shorter duration given evolving conditions

For the six-month period ended April 30, 2017, the Fund outperformed the Benchmark on both an NAV and market price basis. Outperformance was largely due to positive security selection in the high yield asset class, and an allocation to leveraged loans also contributed to relative outperformance.

From a sector perspective, positive security selection in energy-exploration & production, oil field equipment, metals/mining and software/services provided the greatest contributions to relative returns. In contrast, holdings in telecom-satellite and support-services detracted from relative returns. Ratings returns were positive when measured against the Benchmark, with an underweight in BB and positive security selection in B and CCC all contributing positively to relative returns.

The United States economy continues to experience relatively slow, yet stable growth—and the most recent unemployment rate continues to show slight improvement, ending the reporting period at 4.4%. As the commodity and oil markets continue their stabilization in 2017, we expect default rates to continue to decline, with perhaps the exception of certain specific sectors such as retail. The portfolio is currently underweight the retail sector, as we believe that the broader sector (particularly department stores and apparel/goods retailers without a service offering) will continue to be under pressure from online and fast-fashion alternative competitors.

Relatively low rates continue to support corporate balance sheets and credit markets have continued to exhibit strength on the heels of solid fundamental earnings.

The U.S. Federal Reserve (the “Fed”) has continued to increase the federal funds rate at a measured pace, with an increase in March 2017, and we believe further hikes in 2017 are likely. Subsequently, we have continued to maintain a shorter duration in the portfolio with a focus on less rate sensitive bonds. Still, there is the potential for rate volatility in the near term and the long end of the U.S. Treasury curve could witness additional weakening if inflation expectations increase. Additionally, despite the markets favorable reaction to French election results and our continued expectation for current credit conditions to remain supportive of risk assets in the intermediate term, we believe macro headlines and evolving market views on the new administration in the U.S. could potentially create some short-term dislocation in markets.

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 markets, 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 this letter and the Fund holdings described in this document are as of April 30, 2017; these views and Fund holdings may have changed subsequent to these dates. Nothing in this document is a recommendation to purchase or sell securities.

Credit Suisse may waive fees and/or reimburse 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 the change in the net asset value of Fund shares and assumes reinvestment of dividends and distributions, if any, at actual prices pursuant to the Fund’s dividend reinvestment program. Total investment return at market value is based on the change 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 NAV and share price. 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, NAV and market price will fluctuate. Performance information current to the most recent month end is available by calling 1-800-293-1232.

The annualized gross and net expense ratios are 2.21% and 2.05%, respectively.

Total investment return at market value is based on the change 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 NAV and share price.

Notes to Financial Statements

April 30, 2017 (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 principal investment objective is to seek high current income. The Fund also will seek capital appreciation as a secondary objective, to the extent consistent with its objective of seeking 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 generally accepted accounting principles 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. The Fund is considered an investment company for financial reporting purposes under GAAP and follows Accounting Standard Codification (“ASC”) Topic 946 — Financial Services — Investment Companies.

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. These pricing services generally price fixed income securities assuming orderly transactions of an institutional “round lot” size, but some trades occur in smaller “odd lot” sizes which may be effected at lower prices than institutional round lot trades. Structured note agreements are valued in accordance with a dealer-supplied valuation based on changes in the value of the underlying index. Futures contracts are valued daily at the settlement price established by the board of trade or exchange on which they are traded. 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. 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 brokers/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 Board.

Note 2. Significant Accounting Policies (continued)

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.

GAAP established a disclosure hierarchy that categorizes the inputs to valuation techniques used to value assets and liabilities at each 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, 2017 in valuing the Fund’s assets and liabilities carried at fair value:

Assets	Level 1		Level 2		Level 3			Total

Each fair value determination is based on a consideration of relevant factors, including both observable and unobservable inputs. Observable and unobservable inputs that Credit Suisse Asset Management, LLC, the Fund’s investment adviser (“Credit Suisse” or the “Adviser”) considers may include (i) the existence of any contractual restrictions on the disposition of securities; (ii) information obtained from the company, which may include an analysis of the company’s financial statements, the company’s products or intended markets or the company’s technologies; (iii) the price of the same or similar security negotiated at arm’s length in an issuer’s completed subsequent round of financing; (iv) the price and extent of public trading in similar securities of the issuer or of comparable companies; or (v) a probability and time value adjusted analysis of contractual term. Where available and appropriate, multiple valuation methodologies are applied to confirm fair value. To the extent that valuation is based on models or inputs that are less observable or unobservable in the market, determining fair value requires more judgment. Because of the inherent uncertainty of valuation, those estimated values may be materially higher or lower than the values that would have been used had a ready market for the investments existed. Accordingly, the degree of judgment exercised by the Fund in determining fair value is greatest for investments categorized in Level 3. In some circumstances, the inputs used to measure fair value might be categorized within different levels of the fair value hierarchy. In those instances, the fair value measurement is categorized in its entirety in the fair value hierarchy based on the least observable input that is significant to the fair value measurement. Additionally, changes in the market environment and other events that may occur over the life of the investments may cause the gains or losses ultimately realized on these investments to be different from the valuations used at the date of these financial statements.

Note 2. Significant Accounting Policies (continued)

For the six months ended April 30, 2017, there were no transfers between Level 1 and Level 2, but there was $27,550 transferred from Level 2 to Level 3 due to a lack of a pricing source supported by observable inputs and $2,052,035 transferred from Level 3 to Level 2 as a result of the availability of a pricing source supported by observable inputs. All transfers, if any, 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 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.

* Statement of Operations includes both forward foreign currency contracts and foreign currency transactions/translations.

For the six months ended April 30, 2017, the Fund held an average monthly value on a net basis of $16,790,720 in forward foreign currency contracts.

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, 2017:

^(a)  Forward foreign currency 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. Reported net realized gain (loss) from foreign currency transactions arises from sales of foreign currencies; currency gains or losses realized between the trade and settlement dates on securities transactions; and the difference between the amounts of dividends, interest, and foreign withholding taxes recorded on the Fund’s books and the U.S. dollar equivalent of the amounts actually received or paid. Net change in unrealized gains and losses on translation of assets and liabilities denominated in foreign currencies arises from changes in the fair values of assets and liabilities, other than investments, at the end of the period, resulting from changes in exchange rates. The Fund does not isolate that portion of the results of operations resulting from fluctuations in foreign exchange rates on investments from the fluctuations arising from changes in market prices of investments held. Such fluctuations are included with net realized and unrealized gain or loss from investments in the Statement of Operations.

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. To the extent any issuer defaults or a credit event occurs that impacts the issuer, the Fund may halt any additional interest income accruals and consider the realizability of interest accrued up to the date of default or credit event.

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. Dividends and distributions to shareholders of the Fund are recorded on the ex-dividend date and 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 common stock 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.

Note 2. Significant Accounting Policies (continued)

F) FEDERAL INCOME TAXES — No provision is made for federal taxes as it is the Fund’s intention to continue to qualify as a regulated investment company (“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 and state income and federal excise tax returns for tax years for which the applicable statutes of limitations have not expired are subject to examination by the Internal Revenue Service and state departments of revenue.

G) SHORT-TERM INVESTMENTS — The Fund, together with other funds/portfolios advised by Credit Suisse, 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/expense recognized on investment securities.

I) FORWARD FOREIGN CURRENCY CONTRACTS — A forward foreign currency exchange contract (“forward currency contract”) is a commitment to purchase or sell a foreign currency at the settlement date at a negotiated rate. The Fund will enter into forward currency contracts primarily for hedging foreign currency risk. Forward currency contracts are valued at the prevailing forward exchange rate of the underlying currencies and unrealized gain/loss is recorded daily. On the settlement date of the forward currency contract, the Fund records a realized gain or loss equal to the difference between the value of the contract at the time it was opened and the value of the contract at the time it was closed. Certain risks may arise upon entering into forward currency contracts from the potential inability of counterparties to meet the terms of their contracts. The maximum counterparty credit risk to the Fund is measured by the unrealized gain on appreciated contracts. Additionally, when utilizing forward currency contracts to hedge, the Fund forgoes the opportunity to profit from favorable exchange rate movements during the term of the contract. The Fund’s open forward currency contracts at April 30, 2017 are disclosed in the Schedule of Investments.

J) SECURITIES LENDING — The initial collateral received by the Fund is required to have a value of at least 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). The collateral is maintained thereafter at a value equal to at least 102% of the current market value of the securities on loan. The market value of loaned securities is determined at the close of each business day of the Fund and any additional required collateral is delivered to the Fund, or excess collateral returned by the Fund, on the next business day. 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, 2017, the Fund had investment securities on loan with a fair value of $6,977,009. Collateral received for securities loaned and a related liability of $7,115,518 are presented gross in the Statement of Assets and Liabilities. The collateral for securities loaned is valued consistently to the other investments held by the Fund and is included in Level 2 of the fair value hierarchy. For the six months ended April 30, 2017, 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. Securities lending income is accrued as earned. During the six months ended April 30, 2017, total earnings from the Fund’s investment in cash collateral received in connection with securities lending arrangements was $49,451, of which $1,407 was rebated to borrowers (brokers). The Fund retained $36,108 in income from the cash collateral investment, and SSB, as lending agent, was paid $11,936.

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 the normal course of business the Fund trades financial instruments and enters into financial transactions for which risk of potential loss exists due to changes in the market (market risk) or failure of the other party to a transaction to perform (credit risk). Similar to credit risk, the Fund may be exposed to counterparty risk, including securities lending, or the risk that an institution or other entity with which the Fund has unsettled or open transactions will default. The potential loss could exceed the value of the financial assets recorded in the financial statements. Financial assets, which potentially expose the Fund to credit risk, consist principally of cash due from counterparties and investments. The extent of the Fund’s exposure to credit and counterparty risks in respect to these financial assets approximates their carrying value as recorded in the Fund’s Statement of Assets and Liabilities.

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) NEW ACCOUNTING PRONOUNCEMENTS — On August 26, 2016, Financial Accounting Standards Board (“FASB”) issued Accounting Standards Update No. 2016-15, “Statement of Cash Flows (Topic 230), a consensus of the FASB’s Emerging Issues Task Force” (“ASU 2016-15”). ASU 2016-15 is intended to reduce diversity in practice in how certain transactions are classified in the statement of cash flows. The issues addressed in ASU 2016-15 are: debt prepayment or debt extinguishment costs, settlement of zero-coupon debt instruments, contingent consideration payments made after a business combination, proceeds from the settlement of insurance claims, proceeds from the settlement of corporate-owned life insurance policies, including bank-owned life insurance policies, distributions received from equity method investments, beneficial interests in securitization transactions; and, separately identifiable cash flows and application of the predominance principle. ASU 2016-15 is effective for interim and annual reporting periods beginning after December 15, 2017. Management is currently evaluating the impact, if any, of applying this provision.

In November 2016, FASB issued Accounting Standards Update No. 2016-18, “Statement of Cash Flows (Topic 230), Restricted Cash, a consensus of the FASB’s Emerging Issues Task Force” (“ASU 2016-18”). ASU 2016-18 requires that a statement of cash flows explains the change during the period in the total of cash, cash equivalents, and amounts generally described as restricted cash or restricted cash equivalents. Therefore, amounts generally described as restricted cash and restricted cash equivalents should be included with cash and cash equivalents when reconciling the beginning-of-period and end-of-period total amounts shown on the statement of cash flows. The amendments in ASU 2016-18 do not provide a definition of restricted cash or restricted cash equivalents. ASU 2016-18 is effective for interim and annual reporting periods beginning after December 15, 2017. Management is currently evaluating the impact, if any, of applying this provision.

In October 2016, the U.S. Securities and Exchange Commission adopted new rules and amended existing rules (together, “final rules”) intended to modernize the reporting and disclosure of information by registered investment companies. In part, the final rules amend Regulation S-X and require standardized, enhanced disclosure about derivatives in investment company financial statements, as well as other amendments. The compliance date for the amendments to Regulation S-X is August 1, 2017. Management is currently evaluating the impact that the adoption of the amendments to Regulation S-X will have on the Fund’s financial statements and related disclosures.

M) SUBSEQUENT EVENTS — In preparing the financial statements as of April 30, 2017, 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

Credit Suisse serves as investment adviser for the Fund. For its investment advisory services, Credit Suisse is entitled to receive a fee from the Fund at an 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, 2017, investment advisory fees earned and voluntarily waived were $1,731,024 and $210,753, respectively. Fee waivers and expense reimbursements are voluntary and may be discontinued by Credit Suisse at any time.

Note 3. Transactions with Affiliates and Related Parties (continued)

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, 2017, administrative services fees earned by SSB (including out-of-pocket expenses) with respect to the Fund were $33,082.

The Independent Trustees receive fifty percent (50%) of their annual retainer in the form of shares. During the six months ended April 30, 2017 and the year ended October 31, 2016, 10,074 shares and 23,794 shares, respectively, were issued through the Trustees’ compensation plan. Trustees as a group own less than 1% of the Fund’s outstanding shares.

The Fund from time to time purchases or sells loan investments in the secondary market through Credit Suisse or its affiliates acting in the capacity as broker-dealer. Credit Suisse or its affiliates may have acted in some type of agent capacity to the initial loan offering prior to such loan trading in the secondary market.

Note 4. Line of Credit

The Fund has a line of credit provided by SSB primarily to leverage its investment portfolio (the “SSB Agreement”). The Fund may borrow the lesser 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, 2017, the Fund had loans outstanding under the Agreement of $121,000,000. During the six months ended April 30, 2017, the Fund had borrowings under the Agreement as follows:

Average Daily Loan Balance		Weighted Average Interest Rate %			Maximum Daily Loan Outstanding		Interest Paid
$	111,088,398		1.611	%	$	122,000,000	$	899,969

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

31

Credit Suisse High Yield Bond Fund

Note 4. Line of Credit (continued)

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 the Fund’s 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, 2017, purchases and sales of investment securities (excluding short-term investments) were $150,995,174 and $137,047,714, respectively.

Note 6. Fund Shares

The Fund offers a Dividend Reinvestment Plan (the “Plan”) to its common stockholders. By participating in the Plan, dividends and distributions will be promptly paid to stockholders in additional shares of common stock of the Fund. The number of shares to be issued will be determined by dividing the total amount of the distribution payable 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, Computershare (or a broker-dealer selected by Computershare) shall endeavor to apply the amount of such distribution to purchase shares of Fund common stock in the open market.

The Fund has one class of shares of beneficial interest, par value $.001 per share; an unlimited number of shares are authorized. Transactions in shares of beneficial interest of the Fund were as follows:

	For the Six Months Ended April 30, 2017 (unaudited)		For the Year Ended October 31, 2016
Shares issued through the Trustees compensation plan		10,074		23,794
Shares issued through reinvestment of dividends		40,198		66,769
Net increase		50,272		90,563

Note 7. 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 Advisory Agreement (unaudited)

In approving the renewal of the current Advisory Agreement for the Credit Suisse High Yield Bond Fund (the “Fund”), the Board of Trustees of 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 14 and 15, 2016, 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 “Contractual 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 .815% paid by the Fund after taking waivers and breakpoints into account (the “Net Advisory Fee”). 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. However, the Board received assurance from management that the waivers would not be discontinued during the current year.

Additionally, the Board considered information comparing the Contractual Advisory Fee less waivers and/or reimbursements (“Net Advisory Fee”) and the Fund’s overall expenses with those of funds in both the relevant expense group (“Expense Group”) and universe of funds (“Expense Universe”) provided by Broadridge, an independent provider of investment company data. The Board was provided with a description of the methodology used to arrive at the funds included in the Expense Group and the Expense Universe.

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 considered the performance results of the Fund over time, along with comparisons both to the relevant performance group (“Performance Group”) and universe of funds (“Performance Universe”) for the Fund. The Board was provided with a description of the methodology used to arrive at the funds included in the Performance Group and Performance Universe. The Board considered the positive investment performance of the

34

Credit Suisse High Yield Bond Fund

Board Approval of Advisory Agreement (unaudited) (continued)

Fund over various investment periods relative to its stated objectives, as well as the performance of the Fund relative to its peers.

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.    The Board noted that the Fund’s Contractual Advisory Fee had breakpoints that would allow investors to benefit directly in the form of lower fees as Fund assets grow.

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 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:

• The Contractual Advisory Fee and Net Advisory Fee, reviewed along with information provided by Broadridge for funds in the Fund’s Expense Group and Expense Universe, were reasonable in relation to the services provided by Credit Suisse.

• 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.

35

Credit Suisse High Yield Bond Fund

Board Approval of Advisory Agreement (unaudited) (continued)

• 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.
