Credit Suisse High Yield Bond FundAnnual Investment Adviser’s ReportOctober 31, 2018 (unaudited)

November 23, 2018

Dear Shareholder:

We are pleased to present this Annual Report covering the activities of the Credit Suisse High Yield Bond Fund(the “Fund”) for the 12-month period ended October 31, 2018.

Performance Summary11/1/2017 – 10/31/2018

Fund & Benchmark PerformanceTotal Return (based on net asset value (“NAV”))1 0.68%Total Return (based on market value)1 -9.23%ICE BofAML US High Yield Constrained Index2 0.81%

Market Review: A positive period for high yield assets

The annual period ended October 31, 2018, was a positive one for the U.S. high yield asset class. The ICEBofAML US High Yield Constrained Index (the “Index”), the Fund’s benchmark, returned 0.81% for the period.However, yields widened by 137 basis points to 6.89% (yield-to-worst basis) and the Index spread to worstwidened by 26 basis points to 390, as investors navigated tighter monetary policy in the United States anduneasiness in the global economy.

Looking at returns by credit quality, the lower-rated portion of the Index outperformed for the year. CCC andlower-rated bonds posted the highest returns, at 4.57%, followed by single B bonds, which returned 1.67% duringthe period. Conversely, BB high yield bonds returned -0.82% over the period.

From an industry perspective, healthcare, transportation and insurance were the top performers in the Index,with respective returns of 4.62%, 3.14% and 2.07%. Conversely, automotive, banking and consumer goods laggedwith returns of -5.82%, -3.15% and -1.88%, respectively.

For the most part, supply and demand dynamics have been positive for the high yield asset class. Over theperiod, gross high yield bond issuance totaled $228 billion, which is down more than 40% from the priorreporting period.

Based on default activity, the current U.S. high yield credit cycle has likely not reached its final innings. OnOctober 31, 2018, the trailing 12-month default rate (including distressed exchanges) was 2.04%, compared to a25-year average of 2.88%, as measured by J.P. Morgan.

Strategic Review and Outlook: Conditions point to continued positive return potential

For the 12-month period ended October 31, 2018, the Fund slightly underperformed the benchmark on an NAVbasis. Positive security selection within the high yield asset class and in the energy, technology and capital goodssectors all contributed to performance. Additionally, an underweight to BB-rated and an overweight to CCC-rated positions also contributed to relative performance. Given the muted returns for the overall asset class, theimpact of leverage was a drag on NAV return.

In the near term, we expect favorable supply and demand technicals to continue. We also remain positive onunderlying corporate fundamentals as well as solid domestic economic activity. We believe default rates willremain relatively unchanged outside of specific sectors. Longer term, we expect U.S. high yield outperformanceto be driven by credit selection and well-managed industry exposures, as we expect sector returns to diverge.

Additionally, as the high yield asset class is likely to be more prone to interest rate volatility (though less so thanlonger-duration investment grade products), we will look to take advantage of investment opportunities that maybe created by dislocations due to interest rate volatility.

Thomas J. Flannery John G. PoppChief Investment Officer* 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 thosefound 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 numberof 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 otherthings, domestic and foreign markets, industry and economic trends and developments and government regulation, and theirpotential 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 areas of October 31, 2018; these views and Fund holdings may have changed subsequent to these dates. Nothing in thisdocument is a recommendation to purchase or sell securities.

1 Assuming reinvestment of dividends of $0.248 per share.2 The ICE BofAML US High Yield Constrained Index (the “Index”) is an unmanaged index that tracks the performance of

below investment-grade U.S. dollar-denominated corporate bonds issued in the U.S. domestic market, where each issuer’sallocation is limited to 2% of the Index. The Index does not have transaction costs and investors cannot invest directly inthe Index. The Index was previously known as The BofA Merrill Lynch US High Yield Master II Constrained Index.

Credit Suisse may waive fees and/or reimburse expenses, without which performance would be lower. Waivers and/orreimbursements are subject to change and may be discontinued at any time. Returns represent past performance. Totalinvestment return at net asset value is based on the change in the net asset value of Fund shares and assumes reinvestment ofdividends and distributions, if any, at actual prices pursuant to the Fund’s dividend reinvestment program. Totalinvestment return at market value is based on the change in the market price at which the Fund’s shares traded on the stockexchange during the period and assumes reinvestment of dividends and distributions, if any, at actual prices pursuant to theFund’s dividend reinvestment program. Because the Fund’s shares trade in the stock market based on investor demand, theFund 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 thanthe figures shown. The Fund’s yield, return, NAV and market price will fluctuate. Performance information current to themost recent month end is available by calling 1-800-293-1232.

The annualized gross and net expense ratios are 2.74% and 2.59%, respectively.

Credit Suisse High Yield Bond FundNotes to Financial StatementsOctober 31, 2018

Note 1. Organization

Credit Suisse High Yield Bond Fund (the “Fund”) is a business trust organized under the laws of the State ofDelaware on April 30, 1998. The Fund is registered as a non-diversified, closed-end management investmentcompany under the Investment Company Act of 1940, as amended (the “1940 Act”). The Fund’s principalinvestment objective is to seek high current income. The Fund also will seek capital appreciation as a secondaryobjective, 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 itsfinancial statements. The policies are in accordance with generally accepted accounting principles in the UnitedStates of America (“GAAP”). The preparation of financial statements requires management to make estimatesand assumptions that affect the reported amounts and disclosures in the financial statements. Actual results coulddiffer from those estimates. The Fund is considered an investment company for financial reporting purposesunder GAAP and follows the accounting and reporting guidance in Financial Accounting Standards Board’s(“FASB”) Accounting Standards Codification (“ASC”) Topic 946 — Financial Services — Investment Companies.

A) SECURITY VALUATION — The Board of Trustees (the “Board”) is responsible for the Fund’s valuationprocess. The Board has delegated the supervision of the daily valuation process to Credit Suisse who hasestablished a Pricing Committee which, pursuant to the policies adopted by the Board, is responsible for makingfair valuation determinations and overseeing the Fund’s pricing policies. The net asset value of the Fund isdetermined daily as of the close of regular trading on the New York Stock Exchange, Inc. (the “Exchange”) oneach day the Exchange is open for business. The valuations for fixed income securities (which may include, butare not limited to, corporate, government, municipal, mortgage-backed, collateralized mortgage obligations andasset-backed securities) and certain derivative instruments are typically the prices supplied by independent thirdparty pricing services, which may use market prices or broker/dealer quotations or a variety of valuationtechniques and methodologies. The independent third party pricing services use inputs that are observable suchas issuer details, interest rates, yield curves, prepayment speeds, credit risks/spreads, default rates and quotedprices for similar securities. These pricing services generally price fixed income securities assuming orderlytransactions of an institutional “round lot” size, but some trades occur in smaller “odd lot” sizes which may beeffected at lower prices than institutional round lot trades. Structured note agreements are valued in accordancewith a dealer-supplied valuation based on changes in the value of the underlying index. Futures contracts arevalued 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 adaily basis. The currency forward contract pricing model derives the differential in point rates to the expirationdate of the forward and calculates its present value. Equity securities for which market quotations are availableare valued at the last reported sales price or official closing price on the primary market or exchange on whichthey trade. The Fund may utilize a service provided by an independent third party which has been approved bythe Board to fair value certain securities. When fair value pricing is employed, the prices of securities used by theFund to calculate its net asset value may differ from quoted or published prices for the same securities. Ifindependent third party pricing services are unable to supply prices for a portfolio investment, or if the pricessupplied are deemed by the investment adviser to be unreliable, the market price may be determined by theinvestment adviser using quotations from one or more brokers/dealers or at the transaction price if the securityhas recently been purchased and no value has yet been obtained from a pricing service or pricing broker. Whenreliable 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 Fundcalculates its net asset value, these securities will be fair valued in good faith by the Pricing Committee, inaccordance with procedures adopted by the Board.

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

GAAP established a disclosure hierarchy that categorizes the inputs to valuation techniques used to valueassets and liabilities at each measurement date. These inputs are summarized in the three broad levels listedbelow:

• 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 fairvalue of investments)

The inputs or methodologies used to value securities are not necessarily an indication of the risk associatedwith investing in those securities.

The following is a summary of the inputs used as of October 31, 2018 in valuing the Fund’s assets and liabilitiescarried at fair value:

Each fair value determination is based on a consideration of relevant factors, including both observable andunobservable inputs. Observable and unobservable inputs that Credit Suisse Asset Management, LLC, the Fund’sinvestment adviser (“Credit Suisse” or the “Adviser”) considers may include (i) the existence of any contractualrestrictions on the disposition of securities; (ii) information obtained from the company, which may include ananalysis of the company’s financial statements, the company’s products or intended markets or the company’stechnologies; (iii) the price of the same or similar security negotiated at arm’s length in an issuer’s completedsubsequent round of financing; (iv) the price and extent of public trading in similar securities of the issuer or ofcomparable companies; or (v) a probability and time value adjusted analysis of contractual term. Where availableand appropriate, multiple valuation methodologies are applied to confirm fair value. To the extent that valuationis based on models or inputs that are less observable or unobservable in the market, determining fair valuerequires more judgment. Because of the inherent uncertainty of valuation, those estimated values may bematerially higher or lower than the values that would have been used had a ready market for the investmentsexisted. 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 becategorized within different levels of the fair value hierarchy. In those instances, the fair value measurement iscategorized in its entirety in the fair value hierarchy based on the least observable input that is significant to thefair value measurement. Additionally, changes in the market environment and other events that may occur overthe life of the investments may cause the gains or losses ultimately realized on these investments to be differentfrom the valuations used at the date of these financial statements.

For the year ended October 31, 2018, there were no transfers between Level 1 and Level 2, but there was$5,611,716 transferred from Level 2 to Level 3 due to a lack of a pricing source supported by observable inputsand $6,300,759 transferred from Level 3 to Level 2 as a result of the availability of a pricing source supported byobservable 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 toauthoritative guidance on disclosures about derivative instruments and hedging activities which require that afund disclose (a) how and why an entity uses derivative instruments, (b) how derivative instruments andhedging activities are accounted for and (c) how derivative instruments and related hedging activities affect afund’s financial position, financial performance and cash flows.

For the year ended October 31, 2018, the Fund held an average monthly value on a net basis of $21,341,873 inforward 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 TotalReturn, Credit Default and Interest Rate Swaps) and foreign exchange contracts entered into by the Fund. TheMaster Agreements may contain provisions regarding, among other things, the parties’ general obligations,representations, agreements, collateral requirements, events of default and early termination. Termination eventsapplicable to the Fund may occur upon a decline in the Fund’s net assets below a specified threshold over acertain period of time.

Credit Suisse High Yield Bond FundNotes to Financial Statements (continued)October 31, 2018

Note 2. Significant Accounting Policies (continued)

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. Allassets and liabilities denominated in foreign currencies, including purchases and sales of investments, andincome and expenses, are translated into US dollar amounts on the date of those transactions.

The Fund does not isolate that portion of the results of operations resulting from fluctuations in foreignexchange 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 ofOperations.

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 thedifference between the amounts of dividends, interest, and foreign withholding taxes recorded on the Fund’s booksand the U.S. dollar equivalent of the amounts actually received or paid. Net change in unrealized gains and losseson translation of assets and liabilities denominated in foreign currencies arises from changes in the fair values ofassets and liabilities, other than investments, at the end of the period, resulting from changes in exchange rates.

D) SECURITY TRANSACTIONS AND INVESTMENT INCOME/EXPENSE — Security transactions areaccounted for on a trade date basis. Interest income/expense is recorded on the accrual basis. The Fund amortizespremiums and accretes discounts using the effective interest method. Dividend income/expense is recorded onthe ex-dividend date. The cost of investments sold is determined by use of the specific identification method forboth financial reporting and income tax purposes. To the extent any issuer defaults or a credit event occurs thatimpacts the issuer, the Fund may halt any additional interest income accruals and consider the realizability ofinterest accrued up to the date of default or credit event.

E) DIVIDENDS AND DISTRIBUTIONS TO SHAREHOLDERS — The Fund declares and pays dividends on amonthly basis and records them on ex-date. Distributions of net realized capital gains, if any, are declared andpaid at least annually. However, to the extent that a net realized capital gain can be reduced by a capital losscarryforward, such gain will not be distributed. Dividends and distributions to shareholders of the Fund arerecorded on the ex-dividend date and are determined in accordance with federal income tax regulations, whichmay differ from GAAP.

The Fund’s dividend policy is to distribute substantially all of its net investment income to its shareholders on amonthly basis. However, in order to provide shareholders with a more consistent yield to the current tradingprice of shares of common stock of the Fund, the Fund may at times pay out less than the entire amount of netinvestment income earned in any particular month and may at times in any month pay out such accumulated butundistributed income in addition to net investment income earned in that month. As a result, the dividends paidby the Fund for any particular month may be more or less than the amount of net investment income earned bythe Fund during such month.

F) FEDERAL AND OTHER TAXES — No provision is made for federal taxes as it is the Fund’s intention tocontinue to qualify as a regulated investment company (“RIC”) under the Internal Revenue Code of 1986, asamended (the “Code”), and to make the requisite distributions to its shareholders, which will be sufficient torelieve 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 ofits income, the diversification of its assets and the distribution of its income. One of these requirements is that the

Note 2. Significant Accounting Policies (continued)

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, otherincome derived with respect to its business of investing in such stock, securities or currencies or net incomederived 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 orliability from an uncertain position only if it is more likely than not that the position is sustainable based solely onits technical merits and consideration of the relevant taxing authority’s widely understood administrativepractices and procedures. The Fund has reviewed its current tax positions and has determined that no provisionfor income tax is required in the Fund’s financial statements. The Fund’s federal and state income and federalexcise tax returns for tax years for which the applicable statutes of limitations have not expired are subject toexamination by the Internal Revenue Service and state departments of revenue.

G) CASH — The Fund’s uninvested cash balance is held in an interest bearing variable rate demand depositaccount at State Street Bank and Trust Company (“SSB”), the Fund’s custodian.

H) CASH FLOW INFORMATION — Cash, as used in the Statement of Cash Flows, is the amount reported inthe Statement of Assets and Liabilities, including domestic and foreign currencies. The Fund invests in securitiesand distributes dividends from net investment income and net realized gains, if any (which are either paid in cashor reinvested at the discretion of shareholders). These activities are reported in the Statement of Changes in NetAssets. Information on cash payments is presented in the Statement of Cash Flows. Accounting practices that donot affect reporting activities on a cash basis include unrealized gain or loss on investment securities andaccretion 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 anegotiated 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 andunrealized gain/loss is recorded daily. On the settlement date of the forward currency contract, the Fund recordsa realized gain or loss equal to the difference between the value of the contract at the time it was opened and thevalue of the contract at the time it was closed. Certain risks may arise upon entering into forward currencycontracts from the potential inability of counterparties to meet the terms of their contracts. The maximumcounterparty 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 favorableexchange rate movements during the term of the contract. The Fund’s open forward currency contracts atOctober 31, 2018 are disclosed in the Schedule of Investments.

J) UNFUNDED LOAN COMMITMENTS — The Fund enters into certain agreements, all or a portion of whichmay be unfunded. The Fund is obligated to fund these loan commitments at the borrowers’ discretion. Fundedand unfunded portions of credit agreements are presented in the Schedule of Investments. As of October 31, 2018,unfunded commitments were as follows:

Credit Suisse High Yield Bond FundNotes to Financial Statements (continued)October 31, 2018

Note 2. Significant Accounting Policies (continued)

Unfunded loan commitments and funded portions of credit agreements are marked to market daily and anyunrealized appreciation or depreciation is included in the Statement of Assets and Liabilities and the Statement ofOperations.

K) SECURITIES LENDING — The initial collateral received by the Fund is required to have a value of at least102% of the market value of domestic securities on loan (including any accrued interest thereon) and 105% of themarket value of foreign securities on loan (including any accrued interest thereon). The collateral is maintainedthereafter at a value equal to at least 102% of the current market value of the securities on loan. The market valueof loaned securities is determined at the close of each business day of the Fund and any additional requiredcollateral is delivered to the Fund, or excess collateral returned by the Fund, on the next business day. Cashcollateral received by the Fund in connection with securities lending activity may be pooled together with cashcollateral 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, inthe event of default or bankruptcy by the other party to the agreement, realization and/or retention of thecollateral may be subject to legal proceedings.

SSB has been engaged by the Fund to act as the Fund’s securities lending agent. As of October 31, 2018, theFund had investment securities on loan with a fair value of $20,646,922. Collateral received for securities loanedand a related liability of $21,168,568 are presented gross in the Statement of Assets and Liabilities. The collateralfor securities loaned is valued consistently with the other investments held by the Fund and is included in Level 2of the fair value hierarchy. As of October 31, 2018, the value of the related collateral exceeded the value of thesecurities loaned.

The Fund’s securities lending arrangement provides that the Fund and SSB will share the net income earnedfrom securities lending activities. Securities lending income is accrued as earned. During the year endedOctober 31, 2018, total earnings from the Fund’s investment in cash collateral received in connection withsecurities lending arrangements was $241,209, of which $123,083 was rebated to borrowers (brokers). The Fundretained $88,551 in income from the cash collateral investment, and SSB, as lending agent, was paid $29,575.

L) OTHER — Lower-rated debt securities (commonly known as “junk bonds”) possess speculativecharacteristics 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 risinginterest rates, highly leveraged issuers may experience financial stress which would adversely affect their abilityto service their principal and interest payment obligations, to meet projected business goals and to obtainadditional financing.

In the normal course of business the Fund trades financial instruments and enters into financial transactions forwhich risk of potential loss exists due to changes in the market (market risk) or failure of the other party to atransaction 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 oropen transactions will default. The potential loss could exceed the value of the financial assets recorded in thefinancial statements. Financial assets, which potentially expose the Fund to credit risk, consist principally of cashdue from counterparties and investments. The extent of the Fund’s exposure to credit and counterparty risks inrespect to these financial assets approximates their carrying value as recorded in the Fund’s Statement of Assetsand Liabilities.

Note 2. Significant Accounting Policies (continued)

In addition, periods of economic uncertainty and changes can be expected to result in increased volatility ofmarket prices of lower-rated debt securities and the Fund’s net asset value.

M) RECENT ACCOUNTING PRONOUNCEMENTS — In March 2017, the FASB issued Accounting StandardsUpdate 2017-08, Receivables—Nonrefundable Fees and Other Costs (Subtopic 310-20): Premium Amortization OnPurchased Callable Debt Securities (“ASU 2017-08”). The update shortens the amortization period for thepremium on certain purchased callable debt securities to the earliest call date. ASU 2017-08 will be effective forannual periods beginning after December 15, 2018. Management is currently assessing the potential impact ofthese changes to future financial statements.

Also, in August 2018, the FASB issued Accounting Standards Update 2018-13, Fair Value Measurement (Topic820): Disclosure Framework—Changes to the Disclosure Requirements for Fair Value Measurement(“ASU 2018-13”). The update provides guidance that eliminates, adds and modifies certain disclosure requirementsfor fair value measurements. ASU 2018-13 will be effective for annual periods beginning after December 15, 2019.Management is currently assessing the potential impact of these changes to future financial statements.

N) SUBSEQUENT EVENTS — In preparing the financial statements as of October 31, 2018, managementconsidered the impact of subsequent events for potential recognition or disclosure in these financial statementsthrough the date of release of this report. No such events requiring recognition or disclosure were identifiedthrough 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 isentitled to receive a fee from the Fund at an annual rate of 1.00% of the first $250 million of the average weeklyvalue of the Fund’s total assets minus the sum of liabilities (other than aggregate indebtedness constitutingleverage) and 0.75% of the average weekly value of the Fund’s total assets minus the sum of liabilities (other thanaggregate indebtedness constituting leverage) greater than $250 million. Effective January 1, 2011, Credit Suissehas agreed to waive 0.15% of the fees payable under the Advisory Agreement up to $200 million and 0.25% of thefees payable under the Advisory Agreement on the next $50 million. For the year ended October 31, 2018,investment advisory fees earned and voluntarily waived were $3,670,574 and $424,999, respectively. Fee waiversand expense reimbursements are voluntary and may be discontinued by Credit Suisse at any time.

SSB serves as Accounting and Administrative Agent for the Fund. For its administrative services, SSB receives afee, exclusive of out-of-pocket expenses, calculated in total for all the Credit Suisse funds/portfoliosco-administered by SSB and allocated based upon the relative average net assets of each fund/portfolio, subject toan annual minimum fee. For the year ended October 31, 2018, administrative services fees earned by SSB(including out-of-pocket expenses) with respect to the Fund were $72,934.

Prior to March 12, 2018, the Independent Trustees received a minimum of fifty percent (50%) of their annualretainer in the form of shares. During the year ended October 31, 2018 and 2017, 8,121 shares and 19,469 shares,respectively, were issued through the Trustees’ compensation plan. Trustees as a group own less than 1% of theFund’s outstanding shares.

Credit Suisse High Yield Bond FundNotes to Financial Statements (continued)October 31, 2018

Note 4. Line of Credit

The Fund has a line of credit provided by SSB primarily to leverage its investment portfolio (the “Agreement”).The Fund may borrow the lesser of: a) $160,000,000; b) an amount that is no greater than 33 1/3% of the Fund’stotal assets minus the sum of liabilities (other than aggregate indebtedness constituting leverage); and c) theBorrowing Base as defined in the Agreement. Under the terms of the Agreement, the Fund pays a commitmentfee of 0.25% on the unused amount. In addition, the Fund pays interest on borrowings at LIBOR plus a spread. AtOctober 31, 2018, the Fund had loans outstanding under the Agreement of $124,000,000. The Agreement wasrenewed on November 30, 2018 with a new termination date of November 29, 2019. During the year endedOctober 31, 2018, the Fund had borrowings under the Agreement as follows:

Average DailyLoan Balance

Weighted AverageInterest Rate %

Maximum DailyLoan Outstanding Interest Expense

$126,126,027 2.58% $134,000,000 $3,300,558

The use of leverage by the Fund creates an opportunity for increased net income and capital appreciation forthe Fund, but, at the same time, creates special risks, and there can be no assurance that a leveraging strategy willbe successful during any period in which it is employed. The Fund intends to utilize leverage to provide theshareholders with a potentially higher return. Leverage creates risks for shareholders including the likelihood ofgreater volatility of net asset value and market price of the Fund’s shares and the risk that fluctuations in interestrates on borrowings and short-term debt may affect the return to shareholders. To the extent the income or capitalappreciation 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 capitalappreciation from the securities purchased with such funds is not sufficient to cover the cost of leverage, thereturn to the Fund will be less than if leverage had not been used, and therefore the amount available fordistribution to shareholders as dividends and other distributions will be reduced. In the latter case, Credit Suissein its best judgment nevertheless may determine to maintain the Fund’s leveraged position if it deems such actionto be appropriate under the circumstances. During periods in which the Fund is utilizing leverage, themanagement fee will be higher than if the Fund did not utilize a leveraged capital structure because the fee iscalculated 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 creditagreements, including those relating to asset coverage and portfolio composition requirements. The securitiesheld by the Fund are subject to a lien granted to the lender, to the extent of the borrowing outstanding and anyadditional expenses. The Fund’s lenders may establish guidelines for borrowing which may impose assetcoverage 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 willcontinue 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’saccess 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 ina decision by lenders not to extend credit to the Fund. In addition, a decline in market value of the Fund’s assetsmay have particular adverse consequences in instances where the Fund has borrowed money based on themarket value of those assets. A decrease in market value of those assets may result in the lender requiring theFund to sell assets at a time when it may not be in the Fund’s best interest to do so.

Credit Suisse High Yield Bond FundNotes to Financial Statements (continued)October 31, 2018

Note 8 . Income Tax Information and Distributions to Shareholders (continued)The tax character of distributions paid by the Fund during the fiscal years ended October 31, 2018 and 2017,

respectively, was as follows:Ordinary Income Return of Capital2018 2017 2018 2017

$21,867,417 $22,332,510 $3,775,810 $4,663,429

The tax basis components of distributable earnings differ from the amounts reflected in the Statement of Assetsand Liabilities by temporary book/tax differences. These differences are primarily due to differing treatments ofwash sales and mark to market of forward contracts. At October 31, 2018, the components of distributableearnings on a tax basis were as follows:

Accumulated realized loss $(23,081,803)Unrealized depreciation (12,984,878)

$(36,066,681)

At October 31, 2018, the Fund had unlimited long-term capital loss carryforwards available to offset possiblefuture capital gains as follows:

Unlimited Long-TermLoss Carryforwards

$23,081,803

Unrealized appreciation $ 5,581,320Unrealized depreciation (18,476,346)

Net unrealized appreciation (depreciation) $ (12,895,026)

To adjust for current period permanent book/tax differences which arose principally from differing book/taxtreatment of foreign currency gain/loss and defaulted bonds, paid-in capital was charged $6,207,499, anddistributable earnings/loss was credited $6,207,499. Net assets were not affected by this reclassification.

Note 9. Contingencies

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

If you are a beneficial owner of the Fund having your shares registered inthe name of a bank, broker or other nominee, you must first make arrangements with the organization in whosename your shares are registered to have the shares transferred into your own name.

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

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

Computershare will purchase sharesfor 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 ratashare 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 saleof your shares held in the Plan. Your withdrawal will be effective immediately if your notice is received byComputershare prior to any dividend or distribution record date; otherwise, such termination will be effectiveonly with respect to any subsequent dividend or distribution.
