Credit Suisse High Yield Bond Fund

Semiannual Investment Adviser’s Report

April 30, 2024 (unaudited)

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, 2024 (the “Period”).

Performance Summary

11/1/2023 – 04/30/24

Fund & Benchmark	Performance
Total Return (based on net asset value (“NAV”))1		11.51	%
Total Return (based on market value)1		15.80	%
ICE BofA US High Yield Constrained Index2		8.96	%

¹  Assuming reinvestment of distributions.

²  The ICE BofA 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’s allocation is limited to 2% of the Index. The Index does not have transaction costs and investors cannot invest directly in the Index.

Market Review: A Positive Period for High Yield Assets

The Period was positive for the high yield market. Risk assets rallied late in 2023 with the ICE BofA US High Yield Constrained Index (the “Index”), returning 4.57% in November, 3.69% in December, and 8.96% for the Period. Yields within the high yield asset class declined to end the Period at 8.08%—133 basis points lower than on October 31, 2023. Spreads also declined significantly, down 120 basis points over the Period to end at 331 basis points.

Index returns were heavily driven by CCC-rated bonds, as investors grew more comfortable with riskier credit. CCC bonds gained 12.12% over the Period, while BB-rated bonds returned 8.30% to slightly underperform, and B-rated bonds gained 8.93% to perform in line with the Index.

Over the Period, the best performing sectors included life insurance, auto loans and department stores, returning 21.80%, 19.60% and 18.23%, respectively. The worst performing sectors were discount stores, cable & satellite TV, and telecom-wireline integrated & services, respectively losing -1.57% and gaining 1.49% and 2.96%.

Default activity has trended below longer-term averages to outperform expectations for the Period. According to JP Morgan, the default rate (including distressed exchanges) ended the Period at 2.33%, which is up slightly over the last twelve months, though down 52 basis points since the end of 2023. There has been an uptick in distressed exchange activity, predominantly in the leveraged loan markets. In general, however, open capital markets, especially the burgeoning private credit asset class, have enabled lower-than-expected defaults.

Fund flows for high yield mutual funds have been somewhat quiet. Following $7.0 billion of outflows in 2023, year-to-date outflows have been $0.2 billion.

High yield primary issuance activity increased over the Period, at least in terms of gross volume. Total high yield new issuance of $114.0 billion year-to-date through April 30, compares to $58.9 billion over the same period in 2023. However, net activity excluding refinancings is flat at $21.6 billion. We expect refinancings will continue to dominate as the primary use of proceeds for new deals due to the currently inverted yield curve and tight spreads compared to other credit markets.

Strategic Review and Outlook: Optimism Tempered with Mindfulness

For the Period April 30, 2024, the Fund outperformed the Index on both an NAV and market-price basis.

The Fund’s allocation to high yield and collateralized loan obligations (“CLOs”) contributed to relative performance, while negative selection within the bank loan sector detracted from relative returns. Sectors that contributed to relative returns included capital goods, services, and telecommunications, while automotive was the largest detractor. From a ratings perspective, positive selection within B-rated and CCC-rated investments contributed to performance, while negative selection within CC-rated and not rated positions detracted.

After a significant rally in the fourth quarter of 2023, there has been a stagnant market in early 2024 with bond coupons only marginally offsetting negative price returns. Inflation data in the United States have surprised to the upside and interest rates in the world’s largest economy will remain higher for longer. High yield bond spreads have tightened against an uptick in government bond yields, and we believe strong technical factors and healthy fundamentals have supported that move. Demand for high yield bonds exceeds supply given both the current low net issuance volume and the reduction in outstanding bonds that resulted from rating agency upgrades. Retail mutual fund flows have stabilized, and we believe investors have elevated cash balances. The fundamentals of high yield issuers remain sound, and we do not expect a material increase in distressed activity this year.

Looking forward, we are mindful of rising geopolitical tensions in the Middle East, a continuing conflict in Ukraine, and slowly evolving cracks in commercial real estate markets. The health of issuer balance sheets gives us comfort amid the uncertainty, and we will continue to focus on credit selection to capture opportunities, as the impacts of higher capital costs and other risks spread throughout the global economy.

Average Annual Returns

April 30, 2024 (unaudited)

	6 Months		1 Year		3 Years		5 Years		10 Years
Net Asset Value (NAV)		11.51%		13.77%		3.20%		5.41%		6.04%
Market Value		15.80%		16.49%		2.34%		4.28%		5.06%

Credit Suisse may waive fees and/or reimburse expenses, without which performance would be lower. Returns represent past performance and do not reflect the deduction of taxes that a shareholder would pay on Fund distributions or the sale of Fund shares. Total investment return at NAV is based on the change in the NAV of Fund shares and assumes reinvestment of dividends, capital gains, and return of capital distributions, if any, at 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 NYSE American during the period and assumes reinvestment of dividends, capital gains, and return of capital distributions, if any, at 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 3.92% and 3.73%, respectively.

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

²  This amount represents less than $0.01 or $(0.01) per share.

³  Total investment return at net asset value is based on the change in the net asset value of Fund shares and assumes reinvestment of 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 market price. Total returns for periods less than one year are not annualized.

⁴  Annualized.

⁵  Portfolio turnover is calculated by dividing the lesser of total purchases or sales of portfolio securities for the reporting period by the monthly average of portfolio securities owned during the reporting period. Excluded from both the numerator and denominator are amounts relating to derivatives and securities whose maturities or expiration dates at the time of acquisition were one year or less.

Credit Suisse High Yield Bond Fund

Notes to Financial Statements

April 30, 2024 (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 as a diversified, closed-end management investment company under the Investment Company Act of 1940, as amended (the “1940 Act”). 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 the accounting and reporting guidance in Financial Accounting Standards Board (“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 valuation process. The Board has delegated the supervision of the daily valuation process to Credit Suisse Asset Management, LLC (“Credit Suisse” or the “Adviser”), the investment adviser to the Fund during the six months ended April 30, 2024, who has established a Pricing Committee and a Pricing Group, which, pursuant to the policies adopted by the Board, are responsible for making fair valuation determinations and overseeing the Fund’s pricing policies. The net asset value (“NAV”) 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. Investments in open-ended mutual funds are valued at the NAV as reported on each business day and under normal circumstances. Securities for which market quotations are not readily available are valued at their fair value as determined in good faith by the Adviser, as the Board’s valuation designee (as defined in Rule 2a-5 under the 1940 Act), in accordance with the Adviser’s procedures. The Board oversees the Adviser in its role as valuation designee in accordance with the requirements of Rule 2a-5 under the 1940 Act. The Fund may utilize a service provided by an independent third party to fair value certain securities. When fair value pricing is employed, the prices of securities used by the Fund to calculate its NAV may differ from quoted or published prices for the same

26

Credit Suisse High Yield Bond Fund

Notes to Financial Statements (continued)

April 30, 2024 (unaudited)

Note 2. Significant Accounting Policies (continued)

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 Adviser to be unreliable, the market price may be determined by the 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 NAV, these securities will be fair valued in good faith by the Pricing Group, in accordance with procedures established by the Adviser.

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, 2024 in valuing the Fund’s assets and liabilities carried at fair value:

* Weighted by relative fair value

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 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

28

Note 2. Significant Accounting Policies (continued)

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.

For the six months ended April 30, 2024, $2,533,323 was transferred from Level 2 to Level 3 due to a lack of a pricing source supported by observable inputs and $1,939,723 was 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.

The following table presents the fair value and the location of derivatives within the Statement of Assets and Liabilities at April 30, 2024 and the effect of these derivatives on the Statement of Operations for the six months ended April 30, 2024.

Primary Underlying Risk	Derivative Assets		Derivative Liabilities		Realized Gain (Loss)		Net Change in Unrealized Appreciation (Depreciation)
Foreign currency exchange rate Forward contracts	$	28,767	$	55,473	$	12,707	$	(19,831	)

For the six months ended April 30, 2024, the Fund held an average monthly value on a net basis of $5,278,516 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.

^(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, including purchases and sales of investments, and income and expenses, are translated into U.S. dollar amounts on the date of those transactions.

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-dividend 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

30

Credit Suisse High Yield Bond Fund

Notes to Financial Statements (continued)

April 30, 2024 (unaudited)

Note 2. Significant Accounting Policies (continued)

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.

F) FEDERAL AND OTHER 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) CASH — The Fund’s uninvested cash balance is held in an interest bearing variable rate demand deposit account 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 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,

31

Note 2. Significant Accounting Policies (continued)

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, 2024 are disclosed in the Schedule of Investments. At April 30, 2024, the amount of restricted cash held at brokers related to open forward foreign currency contracts was $50,000.

J) UNFUNDED LOAN COMMITMENTS — The Fund enters into certain agreements, all or a portion of which may be unfunded. The Fund is obligated to fund these loan commitments at the borrowers’ discretion. Funded and unfunded portions of credit agreements are presented in the Schedule of Investments. As of April 30, 2024, the Fund had no unfunded commitments.

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

K) 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. The remaining maturities of the securities lending transactions are considered overnight and continuous. Loans are subject to termination by the Fund or the borrower at any time.

SSB has been engaged by the Fund to act as the Fund’s securities lending agent. As of April 30, 2024, the Fund had outstanding loans of securities to certain approved brokers for which the Fund received collateral:

Market Value of Loaned Securities		Market Value of Cash Collateral		Total Collateral
$	5,318,147	$	5,441,925	$	5,441,925

The following table presents financial instruments that are subject to enforceable netting arrangements as of April 30, 2024.

Gross Amounts Not Offset in the Statement of Assets and Liabilities

Gross Asset Amounts Presented in the Statement of Assets and Liabilities(a)		Collateral Received(b)			Net Amount
$	5,318,147	$	(5,318,147	)	$	—

^(a)  Represents market value of loaned securities at period end.

^(b)  The actual collateral received is greater than the amount shown here due to collateral requirements of the security lending agreement.

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. For the six months ended April 30, 2024, total earnings received in connection with securities lending arrangements was $199,136, of which $122,625 was rebated to borrowers (brokers). The Fund retained $57,365 in income, and SSB, as lending agent, was paid $19,146.

L) OTHER — Lower-rated debt securities (commonly known as “junk bonds”) possess speculative characteristics and are subject to greater market fluctuations and risk of lost income and principal than higher-rated debt securities for a variety of reasons. Also, during an economic downturn or substantial period of rising interest rates, highly leveraged issuers may experience financial stress which would adversely affect their ability to service their principal and interest payment obligations, to meet projected business goals and to obtain additional financing.

The United Kingdom’s Financial Conduct Authority (the “FCA”), which regulates LIBOR, has ceased publishing all LIBOR settings. In April 2023, however, the FCA announced that some USD LIBOR settings will continue to be published under a synthetic methodology until September 30, 2024 for certain legacy contracts. The Secured Overnight Financing Rate, or “SOFR,” is a broad measure of the cost of borrowing cash overnight collateralized by U.S. Treasury securities in the purchase agreement (“repo”) market and has been used increasingly on a voluntary basis in new instruments and transactions. On March 15, 2022, the Adjustable Interest Rate Act was signed into law, providing a statutory fallback mechanism to replace LIBOR with a benchmark rate that is selected by the Federal Reserve Board and based on SOFR for certain contracts that reference LIBOR without adequate fallback provisions. On December 16, 2022, the Federal Reserve Board adopted regulations implementing the Adjustable Interest Rate Act by identifying benchmark rates based on SOFR that replaced LIBOR in different categories of financial contracts after June 30, 2023. These regulations apply only to contracts governed by U.S. law, among other limitations. Neither the effect of the LIBOR transition process nor its ultimate success can yet be known. Not all existing LIBOR-based instruments may have alternative rate-setting provisions and there remains uncertainty regarding the willingness and ability of issuers to add alternative rate-setting provisions in certain existing instruments. Parties to contracts, securities or other instruments using LIBOR may disagree on transition rates or the application of applicable transition regulation, potentially resulting in uncertainty of performance and the possibility of litigation. The Fund may have instruments linked to other interbank offered rates that may also cease to be published in the future.

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 with respect to 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 NAV.

Note 3. Transactions with Affiliates and Related Parties

Credit Suisse served as investment adviser for the Fund during the six months ended April 30, 2024. For its investment advisory services, Credit Suisse is entitled to receive a fee from the Fund at an annualized 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, 2024, investment advisory fees earned and voluntarily waived were $1,441,284 and $211,338, respectively. These fee waivers and expense reimbursements are voluntary and may be discontinued by Credit Suisse at any time.

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 “Agreement”). The Fund may borrow the lesser of: a) $120,000,000; 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 Agreement. Under the terms of the Agreement, the Fund pays a commitment fee on the unused amount. In addition, the Fund pays interest on borrowings at SOFR plus a spread. At April 30, 2024, the Fund had loans outstanding under the Agreement of $80,000,000. The Agreement was renewed on November 17, 2023 with a new termination date of November 15, 2024, and the maximum dollar amount was reduced to $120,000,000. For the six months ended April 30, 2024, the Fund had borrowings under the Agreement as follows:

Average Daily Loan Balance		Weighted Average Interest Rate %			Maximum Daily Loan Outstanding		Interest Expense		Number of Days Outstanding
$	80,000,000		6.278	%	$	80,000,000	$	2,539,055		182

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 NAV 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 securities held by the Fund are subject to a lien granted to the lender, to the extent of the borrowing outstanding and any additional expenses. The Fund’s lenders may establish guidelines for borrowing which may impose asset coverage or portfolio composition requirements that are more stringent than those imposed by the 1940 Act. There is no guarantee that the Fund’s borrowing arrangements or other arrangements for obtaining leverage will continue to be available, or if available, will be available on terms and conditions acceptable to the Fund. Expiration or termination of available financing for leveraged positions can result in adverse effects to the Fund’s access to liquidity and its ability to maintain leverage positions, and may cause the Fund to incur losses.

Note 4. Line of Credit (continued)

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, 2024, purchases and sales of investment securities (excluding short-term investments) and U.S. Government and Agency Obligations were as follows:

Investment Securities				U.S. Government/ Agency Obligations
Purchases		Sales		Purchases		Sales
$	77,874,507	$	78,752,482	$	0	$	0

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 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 Trust Company, N.A. (“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 $0.001 per share; an unlimited number of shares are authorized. There were no transactions in shares of beneficial interest of the Fund for the fiscal year ended October 31, 2023 and for the six months ended April 30, 2024.

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.

Note 8. Subsequent Events

On May 1, 2024, Credit Suisse Asset Management, LLC (“Credit Suisse”) merged into UBS Asset Management (Americas) LLC (“UBS AM (Americas)”), with UBS AM (Americas) as the surviving entity, and UBS AM (Americas) became the investment manager to the Fund. Also on May 1, 2024, UBS Asset Management (US) Inc. replaced CSSU as the Fund’s underwriter and distributor.

Change in Independent Registered Public Accounting Firm (unaudited)

On April 23, 2024, the Fund’s Board approved the dismissal of PricewaterhouseCoopers LLP (“PwC”) as the independent registered public accounting firm for the Fund, due to PwC’s ceasing to be deemed an independent registered public accounting firm with respect to the Fund after April 30, 2024. The Board’s decision to approve the dismissal of PwC was recommended by the Audit Committee of the Board. PwC’s reports on the Fund’s financial statements for the fiscal periods ended October 31, 2023 and October 31, 2022 contained no adverse opinion or disclaimer of opinion nor were they qualified or modified as to uncertainty, audit scope or accounting principle. During the Fund’s fiscal periods ended October 31, 2023 and October 31, 2022 and the subsequent interim period through April 23, 2024, (i) there were no disagreements with PwC on any matter of accounting principles or practices, financial statement disclosure or auditing scope or procedure, which disagreements, if not resolved to the satisfaction of PwC, would have caused them to make reference to the subject matter of the disagreements in connection with their reports on the Fund’s financial statements for such periods, and (ii) there were no “reportable events” of the kind described in Item 304(a)(1)(v) of Regulation S-K under the Securities Exchange Act of 1934, as amended.

Upon the recommendation of the Audit Committee of the Fund’s Board, the Fund’s Board approved the engagement of Ernst & Young LLP (“EY”) as the Fund’s independent registered public accounting firm for the fiscal year ending October 31, 2024. During the Fund’s fiscal periods ended October 31, 2023 and October 31, 2022 and the subsequent interim period through June 19, 2024, neither the Fund, nor anyone on its behalf, consulted with EY on items which: (i) concerned the application of accounting principles to a specified transaction, either completed or proposed, or the type of audit opinion that might be rendered on the Fund’s financial statements; or (ii) concerned the subject of a disagreement (as defined in paragraph (a)(1)(iv) of Item 304 of Regulation S-K) or reportable events (as described in paragraph (a)(1)(v) of said Item 304).

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 2023). 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 2023).

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.
