Credit Suisse High Yield Bond Fund

Semiannual Investment Adviser’s Report

April 30, 2025 (unaudited)

April 30, 2025

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, 2025 (the “Period”).

Performance Summary

11/1/2024 – 4/30/2025

Fund & Benchmark Performance
Total Return (based on net asset value (“NAV”))1	0.63	%
Total Return (based on market value)1	(0.96	)%
ICE BofA US High Yield Constrained Index (the “Index”)2	1.70	%

1  Assuming reinvestment of distributions.

2  The ICE BofA US High Yield Constrained 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, despite significant volatility in recent months due to economic uncertainty on the heels of the Trump administration’s trade actions. The Index, the Fund’s benchmark, gained 1.70% for the Period.

While coupon income generated 3.3% returns, bond prices detracted from returns, declining 1.6%. The negative price return can be attributed to material credit spread widening as investor sentiment soured and business conditions weakened. This was only partially offset by a price tailwind from a 43 basis-point decline in the 5-year U.S. treasury yield over the Period. High yield spreads increased by 102 basis points to end the Period at 410 basis points, while yields increased by 0.6% to finish at 7.8%.

For the Period, BB-rated bonds outperformed the Index, gaining 2.1%, while B-rated and CCC-rated issues underperformed, gaining 1.5% and 0.4%, respectively. In a period of weakening fundamentals and declining treasury yields, stronger returns are to be expected by higher quality bonds.

From an industry perspective, managed care, auto loans, and food & drug retailers were the best performing sectors, returning 8.0%, 7.6% and 6.3%, respectively. In contrast, the worst performing sectors included media-diversified, department stores, and trucking & delivery, losing 5.3%, 5.2% and 4.1%, respectively.

Importantly, default activity has been quite limited in recent months. According to JP Morgan, the default rate, including distressed exchanges, ended the Period at 1.25%—down 22 basis points from the beginning of 2025 and down 111 basis points over the prior 12-month period. Other than select idiosyncratic cases, we are not seeing a significant wave of corporate bankruptcies in the high yield market.

Although outflows from high yield mutual funds ticked up in April 2025, they were generally stable up to that point. Over the Period, outflows totaled $3.7 billion. In 2024, inflows for high yield totaled $16.3 billion—with $7.7 billion going into ETFs.

Semiannual Investment Adviser’s Report (continued)

April 30, 2025 (unaudited)

New high yield bond issuance, at $76.9 billion year-to-date in 2025, is down 32.5% compared to the same period last year. Again, this can be attributed to the broader market volatility. Primary issuance activity remains heavily weighted toward refinancing transactions with very limited net new capital being raised.

Strategic Review and Outlook: Moving Forward with Cautious Optimism

For the Period, the Fund underperformed the Index on both a NAV and market-price basis.

Positioning in the Bank Loan asset class detracted from relative returns, while collateralized loan obligations (CLOs) added to returns. From a sector standpoint, security selection in energy and retail contributed to relative returns, while basic industry detracted from them. Additionally, positive selection in BB-rated investments also contributed to relative returns.

Following a solid year of high-single digit returns in 2024 (+8.2%), 2025 initially started off strong for the high yield market. Risk assets, however, began to show signs of weakness in February after the first round of tariff headlines and high yield returns turned negative in March. In April, average bond prices were down as much as 2.9% at the low point before rallying back to end the month mostly flat. While the impact of Trump’s trade negotiations may fluctuate from day-to-day, economic conditions have taken a severe hit and have led to wider risk premium pricing. For high yield issuers, we believe earnings growth could be adversely impacted, at least in the near term and potentially longer. Nonetheless, we do believe high yield issuers entered this Period with substantial cushion in their financial positions—and we see opportunities in the market to buy attractive assets at now wider credit spreads.

High yield bonds are lower-quality bonds that are also known as “junk bonds.” Such bonds entail greater risks than those found in higher-rated securities.

In addition to historical information, this report contains forward-looking statements, which may concern, among other things, domestic and foreign 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, 2025; these views and Fund holdings may have changed subsequent to these dates. Nothing in this document is a recommendation to purchase or sell securities.

Average Annual Returns

	6 Months		1 Year		3 Years		5 Years		10 Years
Net Asset Value (NAV)		0.63%		7.57%		7.23%		9.80%		6.62%

UBS AM 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 3.64% and 3.45%, respectively.

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

2  Total investment return at net asset value is based on changes in the net asset value of Fund shares and assumes reinvestment of distributions, if any, at actual prices pursuant to the fund’s dividend reinvestment program. Total investment return at market value is based on changes in the market price at which the Fund’s shares traded on the stock exchange during the period and assumes reinvestment of 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 (See Note 6).

3  Annualized.

4  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, 2025 (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.

UBS Asset Management (Americas) LLC (“UBS AM (Americas)” or the “Adviser”), the investment adviser to the Fund, is registered as an investment adviser with the Securities and Exchange Commission (“SEC”) and as a Commodity Pool Operator with the Commodity Futures Trading Commission. UBS AM (Americas) is an indirect wholly owned subsidiary of UBS Group AG. UBS Group AG is an internationally diversified organization with headquarters in Zurich, Switzerland. UBS Group AG operates in many areas of the financial services industry.

In this reporting period, the Fund adopted Financial Accounting Standards Board (“FASB”) Accounting Standards Update 2023-07, Segment Reporting (“Topic 280”) — Improvements to Reportable Segment Disclosures (“ASU 2023-07”). Adoption of the new standard impacted financial statement disclosures only and did not affect the Fund’s financial position or the results of its operations. An operating segment is defined in Topic 280 as a component of a public entity that engages in business activities from which it may recognize revenues and incur expenses, has operating results that are regularly reviewed by the public entity’s chief operating decision maker (“CODM”) to make decisions about resources to be allocated to the segment and assess its performance, and has discrete financial information available. The Fund’s portfolio management team acts as the Fund’s CODM. The Fund represents a single operating segment, as the CODM monitors the operating results of the Fund as a whole and the Fund’s long-term strategic asset allocation is predetermined in accordance with the Fund’s single investment objective which is executed by the Fund’s portfolio managers as a team. The financial information in the form of the Fund’s portfolio composition, total returns, expense ratios and changes in net assets (i.e., changes in net assets resulting from operations, subscriptions and redemptions) which are used by the CODM to assess the Fund’s comparative benchmarks and to make resource allocation decisions for the Fund’s single segment, is consistent with that presented within the Fund’s financial statements. Segment assets are reflected on the accompanying statement of assets and liabilities as “total assets” and significant segment expenses are listed on the accompanying statement of operations.

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 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 the Adviser, 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

Note 2. Significant Accounting Policies (continued)

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 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.)

26

Note 2. Significant Accounting Policies (continued)

• 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, 2025 in valuing the Fund’s assets and liabilities carried at fair value:

Quantitative Disclosure About Significant Unobservable Inputs

Asset Class	Fair Value At April 30, 2025		Valuation Technique		Unobservable Input		Price Range (Weighted Average)*
Corporate Bonds	$	135,960		Income Approach		Expected Remaining Distribution		$0.00 – $0.76 ($0.76)
Bank Loans		0		Income Approach		Expected Remaining Distribution		0.00 (N/A)

Warrants		0		Income Approach		Expected Remaining Distribution		0.00 (N/A)

* 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 UBS AM (Americas) considers may include (i) 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; (ii) the price of the same or similar security negotiated at arm’s length in an issuer’s completed subsequent round of financing; (iii) the price and extent of public trading in similar securities of the issuer or of comparable companies; or (iv) 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.

For the six months ended April 30, 2025, $2,309,802 was transferred from Level 2 to Level 3 due to a lack of a pricing source supported by observable inputs and $1,816,878 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, 2025 and the effect of these derivatives on the Statement of Operations for the six months ended April 30, 2025.

Primary Underlying Risk	Derivative Assets1		Derivative Liabilities1		Realized Gain (Loss)		Net Change in Unrealized Appreciation (Depreciation)
Foreign currency exchange risk	$	26,818	$	141,741	$	—	$	(199,025	)

1  Generally, the balance sheet location for asset derivatives is unrealized appreciation and for liability derivatives is unrealized depreciation.

For the six months ended April 30, 2025, the Fund held an average monthly value on a net basis of $5,790,994 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, 2025:

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

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

29

Credit Suisse High Yield Bond Fund

Notes to Financial Statements (continued)

April 30, 2025 (unaudited)

Note 2. Significant Accounting Policies (continued)

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 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

30

Credit Suisse High Yield Bond Fund

Notes to Financial Statements (continued)

April 30, 2025 (unaudited)

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, 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 each of the tax years in the four year period ended April 30, 2025, 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, 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, 2025 are disclosed in the Schedule of Investments.

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, 2025, unfunded commitments were as follows:

Borrower	Maturity		Rate			Unfunded Commitment
ARAMSCO, Inc.		10/10/30		4.750	%	$	55,434

Note 2. Significant Accounting Policies (continued)

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 UBS AM (Americas) and may be invested in a variety of investments, including funds advised by SSB or an affiliate, 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, 2025, 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
$	12,346,552	$	12,650,463

The following table presents financial instruments that are subject to enforceable netting arrangements as of April 30, 2025.

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
$	12,346,552	$	(12,346,552	)	$	—

(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, 2025, total earnings received in connection with securities lending arrangements was $157,211, of which $139,028 was rebated to borrowers (brokers). The Fund retained $13,559 in income, and SSB, as lending agent, was paid $4,624.

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.

Note 2. Significant Accounting Policies (continued)

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

UBS AM (Americas) serves as investment adviser for the Fund. For its investment advisory services, UBS AM (Americas) 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, UBS AM (Americas) 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, 2025, investment advisory fees earned and voluntarily waived were $1,462,494 and $210,753, respectively. These fee waivers and expense reimbursements are voluntary and may be discontinued by UBS AM (Americas) at any time.

The Fund from time to time purchases or sells loan investments in the secondary market through UBS AM (Americas) or its affiliates acting in the capacity as broker-dealer. UBS AM (Americas) 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, 2025, the Fund had loans outstanding under the Agreement of $87,000,000. The Agreement was renewed on November 15, 2024 with a new termination date of November 14, 2025. For the six months ended April 30, 2025, 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
$	83,392,265		5.343	%	$	90,000,000	$	2,238,788		181

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

33

Credit Suisse High Yield Bond Fund

Notes to Financial Statements (continued)

April 30, 2025 (unaudited)

Note 4. Line of Credit (continued)

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, UBS AM (Americas) 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. 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, 2025, purchases and sales of investment securities and U.S. Government and Agency Obligations (excluding short-term investments) were as follows:

Investment Securities				U.S. Government/ Agency Obligations
Purchases		Sales		Purchases		Sales
$	87,800,972	$	82,908,342	$	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

34

Note 6. Fund Shares (continued)

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. Transactions in shares of beneficial interest of the Fund were as follows:

	For the Six Months April 30, 2025		For the Year Ended October 31, 2024
Shares issued through reinvestment of dividends		61,862		34,027
Net increase		61,862		34,027

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

In preparing the financial statements as of April 30, 2025, 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.

Credit Suisse High Yield Bond Fund

Board Approval of Advisory Agreement (unaudited)

In approving the renewal of the current investment advisory agreement (the “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 special Microsoft Teams meeting held on November 6, 2024, where the Board discussed information and materials previously provided to them in connection with the renewal of the Advisory Agreement, and at an in-person meeting held on November 11 and 12, 2024, 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 (collectively, the “Contractual Advisory Fee”) in light of the extent and quality of the advisory services provided by UBS Asset Management (Americas) LLC (“UBS AM (Americas)”), the Fund’s investment adviser. The Board also reviewed and considered the voluntary fee waivers currently in place for the Fund and considered the actual fee rate of 0.862% for the fiscal year ended October 31, 2024, paid by the Fund after taking waivers and breakpoints into account (the “Net Advisory Fee”). The Board noted, at the Board’s request, UBS AM (Americas) 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 but had received assurances that such waivers would remain in place over the next year. The Board noted that effective May 1, 2024, Credit Suisse Asset Management, LLC (“Credit Suisse”), the Fund’s previous investment adviser, merged into UBS AM (Americas) LLC, with UBS AM (Americas) as the surviving entity, and UBS AM (Americas) became the investment adviser to the Fund under the Investment Management Agreement.

Additionally, the Board received and considered information comparing the Fund’s Contractual Advisory Fee, Net Advisory Fee and 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. Each fund in the Expense Group and Expense Universe was placed in one of five quintiles for each relevant comparison period, with the first quintile including the funds with the lowest relative expenses and the fifth quintile including funds with the highest relative expenses during the period. The Board noted that, with respect to the Fund’s fees and expenses compared to its peers as presented in a report provided by Broadridge, the Fund’s Contractual Advisory Fee ranked in the fifth quintile relative to its Expense Group, the Fund’s actual management fees (including leveraged assets) ranked in the fourth quintile and third quintile relative to its Expense Group and Expense Universe, respectively, the Fund’s actual management fees (excluding leveraged assets) ranked in the third quintile relative to its Expense Group and Expense Universe, the Fund’s total expenses (including leveraged assets) ranked in the third quintile relative to its Expense Group and Expense Universe, and the Fund’s total expenses (excluding leveraged assets) ranked in the second quintile and third quintile relative to its Expense Group and Expense Universe, respectively.

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 UBS AM (Americas) under the Advisory Agreement. The Board also noted information received at regular meetings throughout the year related to the services rendered by UBS AM (Americas) which, in addition

37

Credit Suisse High Yield Bond Fund

Board Approval of Advisory Agreement (unaudited) (continued)

to portfolio management and investment advisory services set forth in the Advisory Agreement, included credit analysis and research; supervising the day-to-day operations of the Fund’s non-advisory functions, which include accounting, administration, custody, transfer agent and other applicable third party service providers; overseeing and facilitating audits; overseeing the Fund’s credit facility; and supervising and/or preparing applicable Fund filings, disclosures and shareholder reports. The Board noted that the extensive investment advisory services provided by UBS AM (Americas) included broad supervisory responsibility and oversight over other service providers to the Fund. The Board also considered UBS AM (Americas)’s compliance program with respect to the Fund. The Board noted that UBS AM (Americas) reports to the Board about portfolio management and compliance matters on a periodic basis. The Board reviewed background information about UBS AM (Americas), including its Form ADV Part 2 – Disclosure Brochure and Brochure Supplement. The Board considered the background and experience of UBS AM (Americas)’s senior management and the expertise of, and the amount of attention given to the Fund by, senior personnel of UBS AM (Americas). 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, as well as the resources provided to them. The Board evaluated the ability of UBS AM (Americas), 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 UBS AM (Americas) clients for comparable services. The Board acknowledged UBS AM (Americas)’s representation that the services provided to the Fund are more extensive than the services provided in connection with other types of accounts, such as separate accounts, offered by UBS AM (Americas) and the services are also more extensive from those offered and provided to a sub-advised fund. The Board also considered that the services provided by UBS AM (Americas) have expanded over time as a result of regulatory and other developments.

Fund Performance

The Board received and considered performance results of the Fund over the previous year ended August 31, 2024 as well as over the two-, three-, four-, five- and ten-year periods ended August 31, 2024, along with comparisons both to the relevant performance group (“Performance Group”) and universe of funds (“Performance Universe”) for the Fund for the same time periods provided in the Broadridge report. The Board was provided with a description of the methodology used to arrive at the funds included in the Performance Group and the Performance Universe. Each fund in the Performance Universe was placed in one of five quintiles for each relevant comparison period, with the first quintile including the best performing funds and the fifth quintile including the worst performing funds during the period. The Board noted that, with respect to the Fund’s performance compared to its peers as presented in the Broadridge report, the Fund’s performance ranked in the first quintile relative to its Performance Universe for the two-, three-, four-, five-, and ten-year periods reported, and the Fund’s performance ranked in the third quintile relative to its Performance Universe for the one-year period reported. The Board considered that the Fund has continued to trade relatively well, at a small premium to net asset value, based on Lipper data provided by UBS AM (Americas) reflecting the Fund’s historical share price and net asset value. The Board also considered the investment performance of the Fund relative to its stated objectives.

Investment Adviser Profitability

The Board received and considered a profitability analysis of Credit Suisse, as the investment adviser to the Fund prior to May 1, 2024, 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

38

Credit Suisse High Yield Bond Fund

Board Approval of Advisory Agreement (unaudited) (continued)

other. The Board deliberations also reflected, in the context of Credit Suisse’s profitability, Credit Suisse’s methodology for allocating costs to the Fund, recognizing that cost allocation methodologies are inherently subjective. The Board also received net profitability information for the other funds in the Credit Suisse family of funds, which include both open-end and closed-end funds. The Board also reviewed Credit Suisse’s profit margin as reflected in the profitability analysis, as well as reviewing profitability in light of appropriate court cases and the services rendered to the Fund. The Board noted that UBS AM (Americas)’s profitability with respect to the Credit Suisse family of funds was expected to be in line with that of Credit Suisse.

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 for the Fund. 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, as well as the current voluntary expense waiver. Additionally, at times when the Fund’s shares have traded at a premium to its net asset value, the Fund has endeavored to conduct at-the-market offerings to raise additional assets, most recently in 2017. The Board also noted that further economies of scale potentially could be realized once the Fund’s shares again traded at a premium to net asset value whereby an additional at-the-market offering could be conducted to increase the Fund’s assets. The Board received information regarding UBS AM (Americas)’s profitability in connection with providing advisory services to the Fund, including UBS AM (Americas)’s costs in providing the services.

Other Benefits to UBS AM (Americas)

The Board considered other benefits received by UBS AM (Americas) and its affiliates as a result of their relationship with the Fund. Such benefits include, among others, benefits potentially derived from an increase in UBS AM (Americas)’s businesses and its reputation as a result of its relationship with the Fund (such as the ability to market its advisory services to other clients and investors including separate account or third party sub-advised mandates or other financial products offered by UBS AM (Americas) and its affiliates).

The Board considered the standards UBS AM (Americas) applied in seeking best execution and UBS AM (Americas)’s policies and practices regarding soft dollars and reviewed UBS AM (Americas)’s method for allocating portfolio investment opportunities among its advisory clients.

Other Factors and Broader Review

As discussed above, the Board reviewed detailed materials received from UBS AM (Americas) 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 and reviews reports of UBS AM (Americas) at least quarterly, which include, among other things, detailed portfolio and market reviews, detailed fund performance reports, and UBS AM (Americas)’s compliance procedures.

Conclusions

In selecting UBS AM (Americas), 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 the funds in the Fund’s Expense Group and Expense Universe, were reasonable in relation to the services provided by UBS AM (Americas).

39

Credit Suisse High Yield Bond Fund

Board Approval of Advisory Agreement (unaudited) (continued)

• The Board was satisfied with the nature, extent and quality of the investment advisory services provided to the Fund by UBS AM (Americas) and that, based on dialogue with management and counsel, the services provided by UBS AM (Americas) under the Advisory Agreement are typical of, and consistent with, those provided to similar mutual funds by other investment advisers.

• In light of the costs of providing investment advisory and other services to the Fund and UBS AM (Americas)’s ongoing commitment to the Fund and willingness to waive fees, UBS AM (Americas)’s net profitability based on fees payable under the Advisory Agreement, as well as other ancillary benefits that UBS AM (Americas)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 2024). 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 2024).

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.
