Credit Suisse High Yield Bond Fund

Annual Investment Adviser’s Report

October 31, 2020 (unaudited)

November 30, 2020

Dear Shareholder:

We are pleased to present this Annual Report covering the activities of the Credit Suisse High Yield Bond Fund (the “Fund”) for the 12-month period ended October 31, 2020.

Performance Summary

11/01/19 – 10/31/20

Fund & Benchmark	Performance
Total Return (based on net asset value (“NAV”))1		3.43	%
Total Return (based on market value)1		(10.07	)%
ICE BofA US High Yield Constrained Index2		2.31	%

Market Review: Unexpected Volatility

The annual period ended October 31, 2020, was one of unexpected volatility for the high yield asset class, with the ICE BofA US High Yield Constrained Index (the “Index”), the Fund’s benchmark, returning 2.31% for the period. The high yield market showed strength in the beginning of the period, as a strong economic backdrop highlighted by declining unemployment boosted corporate earnings and declining interest rates helped increase investor appetite for high yield bonds. However, markets plunged in March 2020 as COVID-19 spread throughout the United States. During the month, investors pulled $11.7 billion from U.S. retail funds—causing the average price of the Index to fall to 91.59 on March 31^st, 2020. The high yield bond market recovered in the second quarter as Index and opportunistic credit buyers entered the market, lockdowns and restrictions were lifted in parts of the United States and Europe, and economic activity began to recover. The recovery continued through the summer and early fall, as third quarter earnings steadily improved and investors gained confidence that there would be continued improvement into 2021. The 10-year U.S. treasury rate tightened by 84 basis points over the period, which led to increased interest in the asset class—especially in high quality, long duration bonds. Overall, yields declined slightly and ended the period at 5.68%—15 basis points tighter than November 1^st, 2019—while spreads widened meaningfully to +530 basis points versus +422 basis points.

For the period, BB-rated bonds strongly outperformed the Index, returning 4.97%. Conversely, B-rated bonds underperformed, returning 1.27%, while CCC-rated bonds severely underperformed, losing -4.62%.

From an industry perspective, integrated energy, transport infrastructure & services, and automakers were the best performing sectors, returning 33.71%, 19.51% and 16.65%, respectively. In contrast, the worst performing sectors included department stores, oil field equipment & services, and theaters & entertainment, losing -63.53%, -41.20% and -35.19%, respectively.

Default activity, as measured by JP Morgan, and including distressed exchanges, ended the period at 6.87%—up 402 basis points over the prior 12 months. Macroeconomic weakness from the COVID-19 pandemic and continued energy sector weakness led to the higher default activity. Additionally, while we do expect defaults to remain elevated, we also anticipate a reversion to longer-term averages, as certain larger defaults get removed from the trailing figures in early 2021.

Mutual fund flows have been positive, with $40.0 billion of inflows year-to-date for 2020. In comparison, there were $18.1 billion of inflows for the same period in 2019.

Credit Suisse High Yield Bond Fund

Annual Investment Adviser’s Report (continued)

October 31, 2020 (unaudited)

New high yield bond issuance totaled $387.6 billion for the first 10 months of 2020—an increase of 68% year-over-year. As issuers have accessed the high yield capital markets to increase liquidity reserves, general corporate purposes have accounted for 26% of the total issuance year-to-date, which is a noticeable increase from the 12% of all transactions in 2019. Refinancing activity remains the most common use of new issuance proceeds, accounting for 66% of the total issuance year-to-date, compared to 68% for all of 2019.

Strategic Review and Outlook: Continuing to search for pockets of opportunity

For the 12-month period ended October 31, 2020, the Fund outperformed the Index on an NAV basis. For the one year ended October 31, 2020, Fund performance benefitted from positive returns in the asset class, as well as positive relative returns. Leverage and positive security selection within the bank loan asset class positively impacted performance. From a sector perspective, basic industry, automotive, and technology & electronics (due to combination of positive security selection and allocation) had the greatest positive impact on Fund performance, while negative selection in leisure and services were drags on performance. From a ratings perspective, positive security selection in CCC-rated investments contributed to relative returns.

We have been encouraged by the recovery in performance and liquidity positions of most companies and expect default rates to moderate from their current levels. Going forward, we will look for opportunities to add yield to the portfolio without taking unnecessary credit risk, while we continue to work through the balance of our COVID-exposed positions (primarily in the leisure & entertainment and energy sectors). While the markets and U.S. economy are by no means out of the woods, we remain constructive on the leveraged loan market over the intermediate and long term.

Thomas J. Flannery Chief Investment Officer*	John G. Popp Chief Executive Officer and President**

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

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

In addition to historical information, this report contains forward-looking statements, which may concern, among other things, domestic and foreign 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 October 31, 2020; these views and Fund holdings may have changed subsequent to these dates. Nothing in this document is a recommendation to purchase or sell securities.

¹  Assuming reinvestment of dividends of $0.201 per share.

Credit Suisse may waive fees and/or reimburse expenses, without which performance would be lower. Waivers and/or reimbursements are subject to change and may be discontinued at any time. Returns represent past performance. Total investment return at net asset value is based on the change in the net asset value of Fund shares and assumes reinvestment of dividends and distributions, if any, at actual prices pursuant to the Fund’s dividend reinvestment program. Total investment return at market value is based on the change in the market price at which the Fund’s shares traded on the stock exchange during the period and assumes reinvestment of dividends and distributions, if any, at actual prices pursuant to the Fund’s dividend reinvestment program. Because the Fund’s shares trade in the stock market based on investor demand, the Fund may trade at a price higher or lower than its NAV. Therefore, returns are calculated based on NAV and share price. Past performance is no guarantee of future results. The current performance of the Fund may be lower or higher than the figures shown. The Fund’s yield, return, NAV and market price will fluctuate. Performance information current to the most recent month end is available by calling 1-800-293-1232.

The annualized gross and net expense ratios are 2.18% and 2.00%, 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 dividends and distributions, if any, at actual prices pursuant to the Fund’s dividend reinvestment program. Total investment return at market value is based on the change in the market price at which the Fund’s shares traded on the stock exchange during the period and assumes reinvestment of dividends and distributions, if any, at actual prices pursuant to the Fund’s dividend reinvestment program. Because the Fund’s shares trade in the stock market based on investor demand, the Fund may trade at a price higher or lower than its NAV. Therefore, returns are calculated based on NAV and market price.

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.

Notes to Financial Statements

October 31, 2020

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 non-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, the Fund’s investment adviser (“Credit Suisse” or the “Adviser”), who has established a Pricing Committee which, pursuant to the policies adopted by the Board, is responsible for making fair valuation determinations and overseeing the Fund’s pricing policies. The net asset value of the Fund is determined daily as of the close of regular trading on the New York Stock Exchange, Inc. (the “Exchange”) on each day the Exchange is open for business. The valuations for fixed income securities (which may include, but are not limited to, corporate, government, municipal, mortgage-backed, collateralized mortgage obligations and asset-backed securities) and certain derivative instruments are typically the prices supplied by independent third party pricing services, which may use market prices or broker/dealer quotations or a variety of valuation techniques and methodologies. The independent third party pricing services use inputs that are observable such as issuer details, interest rates, yield curves, prepayment speeds, credit risks/spreads, default rates and quoted prices for similar securities. These pricing services generally price fixed income securities assuming orderly transactions of an institutional “round lot” size, but some trades occur in smaller “odd lot” sizes which may be effected at lower prices than institutional round lot trades. Structured note agreements are valued in accordance with a dealer-supplied valuation based on changes in the value of the underlying index. Futures contracts are valued daily at the settlement price established by the board of trade or exchange on which they are traded. Forward contracts are valued at the London closing spot rates and the London closing forward point rates on a daily basis. The currency forward contract pricing model derives the differential in point rates to the expiration date of the forward and calculates its present value. Equity securities for which market quotations are available are valued at the last reported sales price or official closing price on the primary market or exchange on which they trade. The Fund may utilize a service provided by an independent third party which has been approved by the Board to fair value certain securities. When fair value pricing is employed, the prices of securities used by the Fund to calculate its net asset value may differ from quoted or published prices for the same securities. If independent third party pricing services are unable to supply prices for a portfolio investment, or if the prices supplied are deemed by the investment adviser to be unreliable, the market price may be determined by the investment adviser using quotations from one or more brokers/dealers or at the transaction price if the security has recently been purchased and no value has yet been obtained from a pricing service or pricing broker. When reliable prices are

Note 2. Significant Accounting Policies (continued)

not readily available, such as when the value of a security has been significantly affected by events after the close of the exchange or market on which the security is principally traded, but before the Fund calculates its net asset value, these securities will be fair valued in good faith by the Pricing Committee, in accordance with procedures adopted by the Board.

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

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 October 31, 2020 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 least observable input that is significant to the fair value measurement. Additionally, changes in the market environment and other events that

Note 2. Significant Accounting Policies (continued)

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 year ended October 31, 2020, $3,790,333 was transferred from Level 2 to Level 3 due to a lack of a pricing source supported by observable inputs and $6,537,565 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 October 31, 2020 and the effect of these derivatives on the Statement of Operations for the year ended October 31, 2020.

Primary Underlying Risk	Derivative Assets		Derivative Liabilities		Realized Gain (Loss)			Change in Unrealized Appreciation(Depreciation)
Foreign currency exchange rate forward contracts	$	13,724	$	1,965	$	(121,746	)	$	135,732

For the year ended October 31, 2020, the Fund held an average monthly value on a net basis of $6,136,964 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 October 31, 2020:

The following table presents by counterparty the Fund’s derivative liabilities, net of related collateral pledged by the Fund, at October 31, 2020:

Counterparty	Gross Amount of Derivative Liabilities Presented in the Consolidated Statement of Assets and Liabilities(a)		Financial Instruments and Derivatives Available for Offset		Non-Cash Collateral Pledged		Cash Collateral Pledged		Net Amount of Derivative Liabilities
Deutsche Bank	$	1,965	$	—	$	—	$	—	$	1,965

^(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 US 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-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

29

Credit Suisse High Yield Bond Fund

Notes to Financial Statements (continued)

October 31, 2020

Note 2. Significant Accounting Policies (continued)

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, when utilizing forward currency contracts to hedge, the Fund forgoes the opportunity to profit from favorable

Note 2. Significant Accounting Policies (continued)

exchange rate movements during the term of the contract. The Fund’s open forward currency contracts at October 31, 2020 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 October 31, 2020, the fund has no unfunded loan 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 October 31, 2020, 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
$	2,981,304	$	3,021,285	$	3,021,285

The following table presents financial instruments that are subject to enforceable netting arrangements as of October 31, 2020.

Gross Amounts Not Offset in the Statement of Assets and Liabilities

Gross Asset Amounts Presented in Statement of Assets and Liabilities(a)		Collateral Received(b)			Net Amount (not less than $0)
$	2,981,304	$	(2,981,304	)	$	—

^(a)  Represents market value of loaned securities at year 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. During the year ended October 31, 2020, total earnings from the Fund’s investment in cash collateral received in connection with securities lending arrangements was $72,621, of which $29,660 was rebated to borrowers (brokers). The Fund retained $32,227 in income from the cash collateral investment, and SSB, as lending agent, was paid $10,734.

Note 2. Significant Accounting Policies (continued)

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.

In July 2017, the Financial Conduct Authority, the United Kingdom’s financial regulatory body, announced a desire to phase out the use of LIBOR by the end of 2021.

Although financial regulators and industry working groups have suggested alternative reference rates, such as European Interbank Offer Rate (“EURIBOR”), Sterling Overnight Interbank Average Rate (“SONIA”) and Secured Overnight Financing Rate (“SOFR”), global consensus on alternative rates is lacking and the process for amending existing contracts or instruments to transition away from LIBOR remains uncertain. There also remains uncertainty and risk regarding the willingness and ability of issuers to include fallback provisions and/or other measures that contemplate the discontinuation of LIBOR in new and existing contracts or instruments. In addition, there are obstacles to converting certain longer-term securities and transactions to a new reference rate or rates and the effectiveness of one alternative reference rate versus multiple alternative reference rates in new or existing financial instruments and products has not been determined.

The transition away from LIBOR might lead to increased volatility and illiquidity in markets for instruments whose terms currently reference LIBOR, reduced values of LIBOR-related investments, reduced effectiveness of hedging strategies, increased costs for certain LIBOR-related instruments, increased difficulty in borrowing or refinancing, and prolonged adverse market conditions for the Fund. Furthermore, the risks associated with the expected discontinuation of LIBOR and related transition may be exacerbated if the work necessary to effect an orderly transition to an alternative reference rate is not completed in a timely manner. Because the usefulness of LIBOR as a benchmark could deteriorate during the transition period, these effects could occur prior to the end of 2021.

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

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

M) RECENT ACCOUNTING PRONOUNCEMENTS — In August 2018, the FASB issued Accounting Standards Update 2018-13, Fair Value Measurement (Topic 820): Disclosure Framework — Changes to the Disclosure Requirements for Fair Value Measurement (“ASU 2018-13”). The update provides guidance that eliminates, adds

32

Credit Suisse High Yield Bond Fund

Notes to Financial Statements (continued)

October 31, 2020

Note 2. Significant Accounting Policies (continued)

and modifies certain disclosure requirements for fair value measurements. ASU 2018-13 will be effective for annual periods beginning after December 15, 2019. Management is currently assessing the potential impact of these changes to future financial statements.

The Fund is subject to Accounting Standards Update (ASU) 2017-08, Premium Amortization on Purchased Callable Debt Securities, which shortens the premium amortization period for purchased callable debt securities with noncontingent call features to the earliest call date. The Fund applied the standard on a retrospective basis, as allowed under the standard, beginning with the fiscal year ended October 31, 2019. The identified cost basis of the applicable securities at October 31, 2019 has been adjusted from $365,095,489 to $364,974,995. This change had no impact on total distributable earnings (loss) or the net asset value of the Fund.

In October 2020, FASB issued Accounting Standards Update No. 2020-08 (“ASU 2020-08”), “Receivables — Nonrefundable Fees and Other Costs (Codification Improvements Subtopic 310-20), Premium Amortization on Purchased Callable Debt Securities”. ASU 2020-08 is an update of ASU No. 2017-08, which amends the amortization period of certain purchased callable debt securities held at a premium. ASU 2020-08 updates the amortization period for callable debt securities to be amortized to the next call date. For purposes of this update, the next call date is the first date when a call option at a specified price becomes exercisable. Once that date has passed, the next call date is when the next call option at a specified price becomes exercisable, if applicable. The amendments are effective for fiscal years, and interim periods within those fiscal years, beginning after December 15, 2020. Management has evaluated the implication, if any, of the additional disclosure requirement and the impact is reflected on the Fund’s financial statements.

Note 3. Transactions with Affiliates and Related Parties

Credit Suisse serves as investment adviser for the Fund. For its investment advisory services, Credit Suisse is entitled to receive a fee from the Fund at an 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 year ended October 31, 2020, investment advisory fees earned and voluntarily waived were $3,183,432 and $424,999, respectively. These fee waivers and expense reimbursements are voluntary and may be discontinued by Credit Suisse at any time.

SSB serves as Accounting and Administrative Agent for the Fund. For its administrative services, SSB receives a fee, exclusive of out-of-pocket expenses, calculated in total for all the Credit Suisse funds/portfolios co-administered by SSB and allocated based upon the relative average net assets of each fund/portfolio, subject to an annual minimum fee. For the year ended October 31, 2020, administrative services fees earned by SSB (including out-of-pocket expenses) with respect to the Fund were $70,255.

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.

Credit Suisse High Yield Bond Fund

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) $130,000,000; 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 LIBOR plus a spread. At October 31, 2020, the Fund had loans outstanding under the Agreement of $86,750,000. The Agreement was renewed on November 20, 2020 with a new termination date of November 19, 2021. During the year ended October 31, 2020, 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
$	95,800,546		1.59	%	$	102,250,000	$	1,544,906		366

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

Certain types of borrowings by the Fund may result in the Fund being subject to covenants in credit agreements, including those relating to asset coverage and portfolio composition requirements. The 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 year ended October 31, 2020, 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
$	109,264,709	$	119,841,550	$	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 net asset value per share (“NAV”) of the Fund’s common stock on the payment date, or (ii) 95% of the market price per share of the Fund’s common stock on the payment date. If the NAV of the Fund’s common stock is greater than the market price (plus estimated brokerage commissions) on the payment date, Computershare (or a broker-dealer selected by Computershare) shall endeavor to apply the amount of such distribution to purchase shares of Fund common stock in the open market.

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

	For the Year Ended October 31, 2020		For the Year Ended October 31, 2019
Shares issued through reinvestment of dividends		7,794		21,837
Net increase		7,794		21,837

Note 7. Shelf Offering

Prior to July 18, 2020 Fund had an effective “shelf” registration statement. Effective July 18, 2020, the Fund no longer has an effective registration statement or current prospectus. The shelf registration statement enabled the Fund to issue up to $90,000,000 in proceeds through one or more public offerings. Shares were able to be offered at prices and terms to be set forth in one or more supplements to the Fund’s prospectus included in the shelf registration statement. For the fiscal years of ended October 31, 2020 and October 31, 2019, no common shares of beneficial interest were issued in the shelf offering.

Note 8. Income Tax Information and Distributions to Shareholders

Income and capital gain distributions are determined in accordance with federal income tax regulations, which may differ from GAAP.

The tax character of dividends paid by the Fund during the fiscal years ended October 31, 2020 and 2019, respectively, was as follows:

Ordinary Income				Return of Capital
2020		2019		2020		2019
$	20,010,630	$	19,793,295	$	742,456	$	3,903,530

The tax basis components of distributable earnings differ from the amounts reflected in the Statement of Assets and Liabilities by temporary book/tax differences. These differences are primarily due to differing treatments of wash sales, premium amortization adjustments, defaulted bond accruals, and marked to market of forward contracts.

Accumulated realized loss	$	(23,235,030	)
Unrealized depreciation		(27,606,928	)
	$	(50,841,958	)

At October 31, 2020, the Fund had $23,235,030 of unlimited long-term capital loss carryforwards available to offset possible future capital gains.

During the tax year ended October 31, 2020, the Fund utilized $828,197 of loss carryforwards.

At October 31, 2020, the cost and net unrealized appreciation (depreciation) of investments and derivatives for income tax purposes were as follows:

Cost of Investments	$	346,144,147
Unrealized appreciation	$	8,484,373
Unrealized depreciation		(36,090,511	)
Net unrealized appreciation (depreciation)	$	(27,606,138	)

To adjust for current period permanent book/tax differences which arose principally from differing book/tax treatment of defaulted bond and premium amortization adjustments and foreign currency gain (loss), paid-in capital was credited $130,838 and distributable earnings/loss was charged $130,838. Net assets were not affected by this reclassifications.

Note 9. 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 10. Subsequent Events

In preparing the financial statements as of October 31, 2020, 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.

October 31, 2020

Recent Changes

The following information is a summary of certain changes since October 31, 2019. This information may not reflect all of the changes that have occurred since you purchased the Fund.

During the Fund’s most recent fiscal year, there were no material changes in the Fund’s investment objectives or policies that have not been approved by shareholders or in the principal risk factors associated with investment in the Fund.

Investment Objectives and Policies

The Fund’s primary 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. The Fund is designed for investors willing to assume additional risk in return for the potential for high current income and capital appreciation. The Fund is not intended to be a complete investment program and there can be no assurance that the Fund will achieve its objectives.

Under normal market conditions, the Fund will invest at least 80% of its total assets in fixed income securities of U.S. issuers rated below investment grade quality (lower than Baa by Moody’s Investors Service, Inc. (“Moody’s”) or lower than BBB by Standard & Poor’s, a subsidiary of The McGraw-Hill Companies, Inc. (“S&P”) or comparably rated by another nationally recognized rating agency), or in unrated fixed income securities that Credit Suisse Asset Management, LLC, the Fund’s investment adviser (“Credit Suisse” or the “Investment Adviser”), determines to be of comparable quality. Securities rated lower than Baa by Moody’s and lower than BBB by S&P are commonly known as “junk bonds.” The Fund will generally not invest in securities rated at the time of investment in the lowest rating categories (Ca or below for Moody’s and CC or below for S&P) but may continue to hold securities which are subsequently downgraded. However, it has authority to invest in securities rated as low as C and D by Moody’s and S&P, respectively.

As a component of the Fund’s investment in “junk bonds,” the Fund may also invest up to 20% of its total assets in securities of issuers that are the subject of bankruptcy proceedings or in securities otherwise in default or in significant risk of being in default (“Distressed Securities”). The Fund may invest up to 30% of its total assets in securities of issuers domiciled outside the United States or that are denominated in various foreign currencies or multinational currency units.

In selecting investments for the Fund’s portfolio, the Fund’s portfolio managers:

• continually analyze individual companies, including their financial condition, cash flow and borrowing requirements, value of assets in relation to cost, strength of management, responsiveness to business conditions, credit standing and anticipated results of operations;

• analyze business conditions affecting investments, including:

o changes in economic activity and interest rates;

o availability of new investment opportunities;

o economic outlook for specific industries;

• seek to moderate risk by investing among a variety of industry sectors and issuers.

38

Fund Investment Objectives, Policies and Risks (unaudited) (continued)

October 31, 2020

The portfolio managers may sell securities for a variety of reasons, such as to realize profits, limit losses or take advantage of better investment opportunities.

The Fund currently utilizes and in the future expects to continue to utilize leverage through borrowings, including the issuance of debt securities, or through other transactions, such as reverse repurchase agreements, which have the effect of leverage. The Fund currently is leveraged through borrowings from a credit facility. See “Risks — Leverage Risk” for a brief description of the Fund’s credit agreement with State Street Bank and Trust Company (“State Street”). The Fund may use leverage up to 33¹⁄₃% of its total assets (including the amount obtained through leverage). The Fund generally will not utilize leverage if it anticipates that the Fund’s leveraged capital structure would result in a lower return to shareholders than that obtainable over time with an unleveraged capital structure. There can be no guarantee that the Fund will be able to accurately predict when the use of leverage will be beneficial. Use of leverage creates an opportunity for increased income and capital appreciation for shareholders 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 will seek its secondary objective of capital appreciation by investing in securities that Credit Suisse expects may appreciate in value as a result of favorable developments affecting the business or prospects of the issuer which may improve the issuer’s financial condition and credit rating or as a result of declines in long-term interest rates.

There can be no assurance the Fund’s strategies will be successful.

The Fund invests primarily in bonds, debentures, notes, senior loans (sometimes referred to as bank loans), convertible bonds and preferred stocks. The Fund’s portfolio securities may have fixed or variable rates of interest and may include zero coupon securities, payment-in-kind securities, preferred stock, convertible debt obligations and convertible preferred stock, units consisting of debt or preferred stock with warrants or other equity features, secured floating rate loans and loan participations, government securities, stripped securities, commercial paper and other short-term debt obligations. The issuers of the Fund’s portfolio securities may include domestic and foreign corporations, partnerships, trusts or similar entities, and governmental entities or their political subdivisions, agencies or instrumentalities. The Fund may invest in companies in, or governments of, developing countries. In connection with its investments in corporate debt securities, or restructuring of investments owned by the Fund, the Fund may receive warrants or other non-income producing equity securities. The Fund may retain such securities, including equity shares received upon conversion of convertible securities, until Credit Suisse determines it is appropriate in light of current market conditions to dispose of such securities.

Risk Factors

This section contains a discussion of the general risks of investing in the Fund. The net asset value and market price of, and dividends paid on, the Fund’s common shares of beneficial interest (the “Shares”) will fluctuate with and be affected by, among other things, the risks more fully described below. As with any fund, there can be no guarantee that the Fund will meet its investment objectives or that the Fund’s performance will be positive for any period of time.

Investment and Market Risk. An investment in the Shares is subject to investment risk, including the possible loss of the entire principal amount that you invest. Your investment in Shares represents an indirect investment in the securities owned by the Fund.

39

Credit Suisse High Yield Bond Fund

Fund Investment Objectives, Policies and Risks (unaudited) (continued)

October 31, 2020

The value of these securities, like other market investments, may move up or down, sometimes rapidly and unpredictably, and these fluctuations are likely to have a greater impact on the value of the Shares during periods in which the Fund utilizes a leveraged capital structure. The value of the securities in which the Fund invests will affect the value of the Shares. Your Shares at any point in time may be worth less than your original investment, even after taking into account the reinvestment of Fund dividends and distributions.

Lower Grade Securities Risk. Lower grade securities are regarded as being predominantly speculative as to the issuer’s ability to make payments of principal and interest. Investment in such securities involves substantial risk. Issuers of lower grade securities may be highly leveraged and may not have available to them more traditional methods of financing. Therefore, the risks associated with acquiring the securities of such issuers generally are greater than is the case with higher-rated securities. For example, during an economic downturn or a sustained period of rising interest rates, issuers of lower grade securities may be more likely to experience financial stress, especially if such issuers are highly leveraged. During periods of economic downturn, such issuers may not have sufficient revenues to meet their interest payment obligations. The issuer’s ability to service its debt obligations also may be adversely affected by specific issuer developments, the issuer’s inability to meet specific projected business forecasts or the unavailability of additional financing. The risk of loss due to default by the issuer is significantly greater for the holders of lower grade securities because such securities may be unsecured and may be subordinate to other creditors of the issuer. Other than with respect to Distressed Securities, discussed below, the lower grade securities in which the Fund may invest do not include instruments which, at the time of investment, are in default or the issuers of which are in bankruptcy. However, there can be no assurance that such events will not occur after the Fund purchases a particular security, in which case the Fund may experience losses and incur costs.

Distressed Securities Risk. As a component of the Fund’s investment in “junk bonds,” the Fund may invest up to 20% of its total assets in Distressed Securities. Such securities are the subject of bankruptcy proceedings or otherwise in default as to the repayment of principal and/or payment of interest at the time of acquisition by the Fund or are rated in the lower rating categories (Ca or lower by Moody’s and CC or lower by S&P) or which, if unrated, are in the judgment of Credit Suisse of equivalent quality. Investment in Distressed Securities is speculative and involves significant risk. Distressed Securities frequently do not produce income while they are outstanding and may require the Fund to bear certain extraordinary expenses in order to protect and recover its investment. Therefore, to the extent the Fund pursues its secondary objective of capital appreciation through investment in Distressed Securities, the Fund’s ability to achieve current income for shareholders may be diminished.

Credit Risk. Credit risk is the risk that one or more of the Fund’s investments in debt securities or other instruments will decline in price, or fail to pay interest, liquidation value or principal when due, because the issuer of the obligation or the issuer of a reference security experiences an actual or perceived decline in its financial status. In addition to the credit risks associated with high yield securities, the Fund could also lose money if the issuer of other debt obligations, or the counterparty to a derivatives contract, repurchase agreement, loan of portfolio securities or other obligation, is, or is perceived to be, unable or unwilling to make timely principal and/or interest payments, or to otherwise honor its obligations. The downgrade of a security may further decrease its value.

Interest Rate Risk. Generally, when market interest rates rise, the prices of debt obligations fall, and vice versa. Interest rate risk is the risk that debt obligations and other instruments in the Fund’s portfolio will decline in value because of increases in market interest rates. The Fund may be subject to a greater risk of rising interest

40

Credit Suisse High Yield Bond Fund

Fund Investment Objectives, Policies and Risks (unaudited) (continued)

October 31, 2020

rates due to the recent period of historically low rates and the effect of potential government fiscal policy initiatives and resulting market reaction to those initiatives. The prices of long-term debt obligations generally fluctuate more than prices of short-term debt obligations as interest rates change. During periods of rising interest rates, the average life of certain types of securities may be extended due to slower than expected payments. This may lock in a below market yield, increase the security’s duration and reduce the security’s value. The Fund’s use of leverage will tend to increase interest rate risk.

Investments in floating rate debt instruments, although generally less sensitive to interest rate changes than longer duration fixed rate instruments, may nevertheless decline in value in response to rising interest rates if, for example, the rates at which they pay interest do not rise as much, or as quickly, as market interest rates in general. Conversely, floating rate instruments will not generally increase in value if interest rates decline. Inverse floating rate debt securities also may exhibit greater price volatility than a fixed rate debt obligation with similar credit quality. To the extent the Fund holds floating rate instruments, a decrease (or, in the case of inverse floating rate securities, an increase) in market interest rates will adversely affect the income received from such securities and the net asset value of the Fund’s common shares.

Leverage Risk. The Fund currently leverages through borrowings from a credit facility. The use of leverage, which can be described as exposure to changes in price at a ratio greater than the amount of equity invested, through borrowings or other forms of market exposure, magnifies both the favorable and unfavorable effects of price movements in the investments made by the Fund. Insofar as the Fund continues to employ leverage in its investment operations, the Fund will be subject to substantial risks of loss.

Therefore, if the market value of the Fund’s investment portfolio declines, any leverage will result in a greater decrease in net asset value to common shareholders than if the Fund were not leveraged. Such greater net asset value decrease will also tend to cause a greater decline in the market price for the common shares. Further, if at any time while the Fund has leverage outstanding it does not meet applicable asset coverage requirements (as discussed below), it may be required to suspend distributions to common shareholders until the requisite asset coverage is restored. Any such suspension might impair the ability of the Fund to meet the regulated investment company distribution requirements and to avoid Fund-level U.S. federal income and/or excise taxes.

As noted above, the Fund currently leverages through borrowings from a credit facility. The Fund has entered into a revolving credit agreement with State Street (the “Credit Agreement”) to borrow up to the least of: (a) $160,000,000; (b) an amount that is no greater than 33¹⁄₃% 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 Credit Agreement. Such borrowings constitute financial leverage. The Credit Agreement contains customary covenant, negative covenant and default provisions, including covenants that limit the Fund’s ability to incur additional debt or consolidate or merge into or with any person, other than as permitted, or sell, lease or otherwise transfer, directly or indirectly, all or substantially all of its assets. In addition, the Fund agreed not to purchase assets not contemplated by the investment policies and restrictions in effect when the Credit Agreement became effective. Furthermore, the Fund may not incur additional debt from any other party, except for in limited circumstances (e.g., in the ordinary course of business). Such restrictions shall apply only so long as the Credit Agreement remains in effect.

Indebtedness issued under the Credit Agreement is not convertible into any other securities of the Fund. Outstanding amounts would be payable at maturity or such earlier times as required by the Credit Agreement. The Fund may be required to prepay outstanding amounts under the Credit Agreement in the event of the occurrence of certain events of default. The Fund is expected to indemnify the lenders under the Credit

41

Credit Suisse High Yield Bond Fund

Fund Investment Objectives, Policies and Risks (unaudited) (continued)

October 31, 2020

Agreement against certain liabilities they may incur in connection with the Credit Agreement. The Fund is required to pay commitment fees under the terms of the Credit Agreement. With the use of borrowings, there is a risk that the interest rates paid by the Fund on the amount it borrows will be higher than the return on the Fund’s investments. The credit facility with State Street may in the future be replaced or refinanced by one or more credit facilities having substantially different terms, or the Fund may be unable to renew or replace its credit facility upon the termination of the current facility, possibly requiring it to sell portfolio securities at times or prices that are disadvantageous. Any of these situations could adversely impact income or total return to shareholders.

The Fund must comply with investment quality, diversification and other guidelines established by the credit facility. The Fund does not anticipate that such guidelines will have a material adverse effect on the Fund’s common shareholders or its ability to achieve its investment objectives.

Foreign Securities Risk. Investing in securities of foreign entities and securities denominated in foreign currencies involves certain risks not involved in domestic investments, including, but not limited to, fluctuations in foreign exchange rates, future foreign political and economic developments, different legal and accounting systems and the possible imposition of exchange controls or other foreign governmental laws or restrictions. Securities prices in different countries are subject to different economic, financial, political and social factors. Since the Fund may invest in securities denominated or quoted in currencies other than the U.S. dollar, changes in foreign currency exchange rates may affect the value of securities in the Fund and the unrealized appreciation or depreciation of investments. Currencies of certain countries may be volatile and therefore may affect the value of securities denominated in such currencies. The Fund may, but is not obligated to, engage in certain transactions to hedge the currency-related risks of investing in non-U.S. dollar denominated securities. In addition, with respect to certain foreign countries, there is the possibility of expropriation of assets, confiscatory taxation, difficulty in obtaining or enforcing a court judgment, economic, political or social instability or diplomatic developments that could affect investments in those countries. Moreover, individual foreign economies may differ favorably or unfavorably from the U.S. economy in such respects as growth of gross domestic product, rates of inflation, capital reinvestment, resources, self-sufficiency and balance of payments position. Certain foreign investments also may be subject to foreign withholding taxes. These risks often are heightened for investments in smaller, emerging capital markets.

Counterparty Risk. The Fund will be subject to credit risk with respect to the counterparties to the derivative contracts purchased or sold by the Fund. Recently, several broker-dealers and other financial institutions have experienced extreme financial difficulty, sometimes resulting in bankruptcy of the institution. Although the Investment Adviser monitors the creditworthiness of the Fund’s counterparties, there can be no assurance that the Fund’s counterparties will not experience similar difficulties, possibly resulting in losses to the Fund. If a counterparty becomes bankrupt, or otherwise fails to perform its obligations under a derivative contract due to financial difficulties, the Fund may experience significant delays in obtaining any recovery under the derivative contract in a bankruptcy or other reorganization proceeding. The Fund may obtain only a limited recovery or may obtain no recovery in such circumstances.

Illiquid Securities Risk. The Fund may invest in securities for which no readily available market exists or are otherwise considered illiquid. The Fund may not be able readily to dispose of such securities at prices that approximate those at which the Fund could sell such securities if they were more widely traded and, as result of such illiquidity, the Fund may have to sell other investments or engage in borrowing transactions if necessary to raise cash to meet its obligations. Over recent years, regulatory changes have led to reduced liquidity in the marketplace, and the capacity of dealers to make markets in fixed income securities has been outpaced by the

42

Credit Suisse High Yield Bond Fund

Fund Investment Objectives, Policies and Risks (unaudited) (continued)

October 31, 2020

growth in the size of the fixed income markets. Liquidity risk may be magnified in a rising interest rate environment or when investor redemptions from fixed income funds may be higher than normal, due to the increased supply in the market that would result from selling activity. Illiquid securities generally trade at a discount.

Prepayment Risk. If interest rates fall, the principal on bonds and loans held by the Fund may be paid earlier than expected. If this happens, the proceeds from a prepaid security may be reinvested by the Fund in securities bearing lower interest rates, resulting in a possible decline in the Fund’s income and distributions to shareholders.

Preferred Stock Risk. Preferred stocks are unique securities that combine some of the characteristics of both common stocks and bonds. Preferred stocks generally pay a fixed rate of return and are sold on the basis of current yield, like bonds. However, because they are equity securities, preferred stocks provide equity ownership of a company, and the income is paid in the form of dividends. Preferred stocks typically have a yield advantage over common stocks as well as comparably-rated fixed income investments. Preferred stocks are typically subordinated to bonds and other debt instruments in a company’s capital structure, in terms of priority to corporate income, and therefore will be subject to greater credit risk than those debt instruments. Unlike interest payments on debt securities, preferred stock dividends are payable only if declared by the issuer’s board of directors. Preferred stock also may be subject to optional or mandatory redemption provisions.

Senior Loans Risk. The Fund’s investments in senior loans are expected to typically be below investment grade. These investments are considered speculative because of the credit risk of their issuers. Such companies are more likely to default on their payments of interest and principal owed to the Fund, and such defaults could reduce the Fund’s net asset value and income distributions. An economic downturn generally leads to a higher non-payment rate, and a debt obligation may lose significant value before a default occurs. Moreover, any specific collateral used to secure a loan may decline in value or become illiquid, which would adversely affect the loan’s value.

Like other debt instruments, senior loans are subject to the risk of non-payment of scheduled interest or principal. Such non-payment would result in a reduction of income to the Fund, a reduction in the value of the investment and a potential decrease in the net asset value per share of the Fund. There can be no assurance that the liquidation of any collateral securing a loan would satisfy the borrower’s obligation in the event of non-payment of scheduled interest or principal payments, or that such collateral could be readily liquidated. This is particularly the case where a senior loan is not backed by collateral or sufficient collateral at the time such senior loan is issued. In the event of bankruptcy of a borrower, the Fund could experience delays or limitations with respect to its ability to realize the benefits of the collateral securing a senior loan. The collateral securing a senior loan may lose all or substantially all of its value in the event of bankruptcy of a borrower. Some senior loans are subject to the risk that a court, pursuant to fraudulent conveyance or other similar laws, could subordinate such senior loans to presently existing or future indebtedness of the borrower or take other action detrimental to the holders of senior loans including, in certain circumstances, invalidating such senior loans or causing interest previously paid to be refunded to the borrower. If interest were required to be refunded, it could negatively affect the Fund’s performance.

Transactions in senior loans may settle on a delayed basis, resulting in the proceeds from the sale of senior loans not being readily available to make additional investments or to meet the Fund’s redemption obligations. To the extent the extended settlement process gives rise to short-term liquidity needs, the Fund may hold cash, sell investments or temporarily borrow from banks or other lenders.

43

Credit Suisse High Yield Bond Fund

Fund Investment Objectives, Policies and Risks (unaudited) (continued)

October 31, 2020

Second Lien and Other Secured Loans Risk. Second lien loans and other secured loans are subject to the same risks associated with investment in senior loans and bonds rated below investment grade. However, because second lien loans are second in right of payment to one or more senior loans of the related borrower, and other secured loans rank lower in right of payment to second lien loans, they are subject to the additional risk that the cash flow of the borrower and any property securing the loan may be insufficient to meet scheduled payments after giving effect to the more senior secured obligations of the borrower. This risk is generally higher for subordinated unsecured loans or debt, which are not backed by a security interest in any specific collateral. Second lien loans and other secured loans are also expected to have greater price volatility than senior loans and may be less liquid. There is also a possibility that originators will not be able to sell participations in second lien loans and other secured loans, which would create greater credit risk exposure.

Zero Coupon Bond and Payment-In-Kind Securities Risk. Investments in zero-coupon and payment-in-kind securities are subject to certain risks, including that market prices of zero-coupon and payment-in-kind securities generally are more volatile than the prices of securities that pay interest periodically and in cash, and are likely to respond to changes in interest rates to a greater degree than other types of debt securities with similar maturities and credit quality. Because zero-coupon securities bear no interest, their prices are especially volatile. And because zero-coupon bondholders do not receive interest payments, the prices of zero-coupon securities generally fall more dramatically than those of bonds that pay interest on a current basis when interest rates rise. However, when interest rates fall, the prices of zero-coupon securities generally rise more rapidly in value than those of similar interest paying bonds. Under many market and other conditions, the market for zero-coupon and payment-in-kind securities may suffer decreased liquidity making it difficult for the Fund to dispose of them or to determine their current value. In addition, as these securities may not pay cash interest, the Fund’s investment exposure to these securities and their risks, including credit risk, will increase during the time these securities are held in the Fund’s portfolio. Further, to maintain its qualification for treatment as a registered investment company and to avoid Fund-level U.S. federal income and/or excise taxes, the Fund is required to distribute to its shareholders any income it is deemed to have received in respect of such investments, notwithstanding that cash has not been received currently, and the value of paid-in-kind interest. Consequently, the Fund may have to dispose of portfolio securities under disadvantageous circumstances to generate the cash, or may have to leverage itself by borrowing the cash to satisfy this distribution requirement. The required distributions, if any, would result in an increase in the Fund’s exposure to these securities.

Valuation Risk. Unlike publicly traded common stock which trades on national exchanges, there is no central place or exchange for bond trading. Bonds generally trade on an “over-the-counter” market which may be anywhere in the world where buyer and seller can settle on a price. Due to the lack of centralized information and trading, the valuation of bonds may carry more risk than that of common stock. Uncertainties in the conditions of the financial market, unreliable reference data, lack of transparency and inconsistency of valuation models and processes may lead to inaccurate asset pricing. As a result, the Fund may be subject to the risk that when a security is sold in the market, the amount received by the Fund is less than the value of such security carried on the Fund’s books.

Non-Diversified Status. The Fund is classified as a “non-diversified” management investment company under the Investment Company Act of 1940, as amended, which means that the Fund may invest a greater portion of its assets in a limited number of issuers than would be the case if the Fund were classified as a “diversified” management investment company. Accordingly, the Fund may be subject to greater risk with respect to its portfolio securities than a management investment company that is “diversified” because changes in the financial

44

Credit Suisse High Yield Bond Fund

Fund Investment Objectives, Policies and Risks (unaudited) (continued)

October 31, 2020

condition or market assessment of a single issuer may cause greater fluctuations in the net asset value of the Shares.

Market Price, Discount and Net Asset Value of Shares. As with any stock, the price of the Fund’s Shares fluctuates with market conditions and other factors. Shares of the Fund, a closed-end investment company, may trade in the market at a discount from their net asset value.

Potential Yield Reduction. An offering of Shares is expected to present the opportunity to invest in high yielding securities. This expectation is based on the current market environment for high yield debt securities, which could change in response to interest rate levels, general economic conditions, specific industry conditions and other factors. If the market environment for high yield debt securities changes in a manner that adversely affects the yield of such securities, the offering of Shares could cause the Fund to invest in securities that are lower yielding than those in which it is currently invested. In addition, even if the market for high yield debt securities continues to present attractive investment opportunities, there is no assurance that the Fund will be able to invest the proceeds of an offering of Shares in high yielding securities or that other potential benefits of the offering will be realized. An offering of Shares could reduce the Fund’s current dividend yield if the Fund is unable to invest the proceeds of the offering in securities that provide a yield at least equal to the current dividend yield.

Market Risk. The market value of an instrument may fluctuate, sometimes rapidly and unpredictably. These fluctuations, which are often referred to as “volatility,” may cause an instrument to be worth less than it was worth at an earlier time. Market risk may affect a single issuer, industry, commodity, sector of the economy, or the market as a whole. Local, regional or global events such as war, acts of terrorism, the spread of infectious illness or other public health issues, recessions, or other events could have a significant impact on a fund and its investments. Market risk is common to most investments — including stocks, bonds and commodities — and the mutual funds that invest in them. The performance of “value” stocks and “growth” stocks may rise or decline under varying market conditions — for example, value stocks may perform well under circumstances in which growth stocks in general have fallen.

Bonds and other fixed income securities generally involve less market risk than stocks and commodities. However, the risk of bonds can vary significantly depending upon factors such as the issuer’s creditworthiness and a bond’s maturity. The bonds of some companies may be riskier than the stocks of others.

An outbreak of respiratory disease caused by a novel coronavirus (sometimes referred to as “COVID-19”) was first detected in China in December 2019 and has now developed into a global pandemic. This pandemic has resulted in closed borders, enhanced health screenings, disruption of, and delays in, the provision of healthcare services, quarantines, cancellations of events and product orders, disruptions to supply chains and customer activity, as well as general concern and uncertainty. The pandemic, and other pandemics and epidemics that may arise in the future, could affect the economies of many nations, individual companies and the market in general in ways that cannot necessarily be foreseen at the present time. In addition, the effect of infectious diseases in developing or emerging market countries may be greater due to less established health care systems. Health crises caused by the novel coronavirus pandemic may exacerbate other pre-existing political, social and economic risks in certain countries. As a result, the extent to which the pandemic may negatively affect a fund’s performance or the duration of any potential business disruption is uncertain. The effects of the pandemic may last for an extended period of time.

Anti-Takeover Provisions. The Fund’s Agreement and Declaration of Trust (the “Declaration of Trust”) contains provisions limiting (i) the ability of other entities or persons to acquire control of the Fund, (ii) the Fund’s

45

Credit Suisse High Yield Bond Fund

Fund Investment Objectives, Policies and Risks (unaudited) (continued)

October 31, 2020

freedom to engage in certain transactions, and (iii) the ability of the Board or shareholders to amend the Declaration of Trust. These provisions of the Declaration of Trust may be regarded as “anti-takeover” provisions. These provisions could have the effect of depriving the shareholders of opportunities to sell their Shares at a premium over prevailing market prices by discouraging a third party from seeking to obtain control of the Fund in a tender offer or similar transaction.

Credit Suisse High Yield Bond Fund

Dividend Reinvestment and Cash Purchase Plan (unaudited)

Credit Suisse High Yield Bond Fund (the “Fund”) offers a Dividend Reinvestment and Cash Purchase Plan (the “Plan”) to its common stockholders. The Plan offers common stockholders a prompt and simple way to reinvest net investment income dividends and capital gains and other periodic distributions in shares of the Fund’s common stock. Computershare Trust Company, N.A. (“Computershare”) acts as Plan Agent for stockholders in administering the Plan.

If your shares of common stock of the Fund are registered in your own name, you will automatically participate in the Plan, unless you have indicated that you do not wish to participate and instead wish to receive dividends and capital gains distributions in cash. If you are a beneficial owner of the Fund having your shares registered in the name of a bank, broker or other nominee, you must first make arrangements with the organization in whose name your shares are registered to have the shares transferred into your own name. Registered shareholders can join the Plan via the Internet by going to www.computershare.com, authenticating your online account, agreeing to the Terms and Conditions of online “Account Access” and completing an online Plan Enrollment Form. Alternatively, you can complete the Plan Enrollment Form and return it to Computershare at the address below.

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

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

The Plan also permits participants to purchase shares of the Fund through Computershare. You may invest $100 or more monthly, with a maximum of $100,000 in any annual period. Computershare will purchase shares for you on the open market on the 25th of each month or the next trading day if the 25th is not a trading day.

There is no service fee payable by Plan participants for dividend reinvestment. For voluntary cash payments, Plan participants must pay a service fee of $5.00 per transaction. Plan participants will also be charged a pro rata share of the brokerage commissions for all open market purchases ($0.03 per share as of October 2006). Participants will also be charged a service fee of $5.00 for each sale and brokerage commissions of $0.03 per share (as of October 2006).

You may terminate your participation in the Plan at any time by notifying Computershare or requesting a sale of your shares held in the Plan. Your withdrawal will be effective immediately if your notice is received by Computershare prior to any dividend or distribution record date; otherwise, such termination will be effective only with respect to any subsequent dividend or distribution. Your dividend participation option will remain the same unless you withdraw all of your whole and fractional Plan shares, in which case your participation in the Plan will be terminated and you will receive subsequent dividends and capital gains distributions in cash instead of shares.

CREDIT SUISSE ASSET MANAGEMENT, LLC

CREDIT SUISSE FUNDS

PROXY VOTING PROCEDURES

Introduction

Credit Suisse Asset Management, LLC (“Credit Suisse”) is a fiduciary that owes each of its client’s duties of care and loyalty with respect to proxy voting. The duty of care requires Credit Suisse to monitor corporate events and to vote proxies. To satisfy its duty of loyalty, Credit Suisse must cast proxy votes in the best interests of each of its clients.

The Credit Suisse Funds (the “Funds”), which have engaged Credit Suisse Asset Management, LLC as their investment adviser, are of the belief that the proxy voting process is a means of addressing corporate governance issues and encouraging corporate actions both of which can enhance shareholder value.

Procedures

The Proxy Voting Procedures (the “Procedures”) set forth below are designed to ensure that proxies are voted in the best interests of Credit Suisse’s clients. The Procedures addresses particular issues and gives a general indication of how Credit Suisse will vote proxies. The Procedures are not exhaustive and does not include all potential issues.

Proxy Voting Committee

The Proxy Voting Committee will consist of a disinterested member of the Portfolio Management Department, a member of the General Counsel Department, a member of the Compliance and Regulatory Affairs Department, a member of the Operations Department (or their designees), and a member of Fund Administration. The purpose of the Proxy Voting Committee is to administer the voting of all clients’ proxies in accordance with the Procedures. The Proxy Voting Committee will review the Procedures as necessary to ensure that it is designed to promote the best interests of Credit Suisse’s clients.

For the reasons disclosed below under “Conflicts,” the Proxy Voting Committee has engaged the services of an independent third party (initially, Risk Metrics Group’s ISS Governance Services Unit (“ISS”)) to assist in issue analysis and vote recommendation for proxy proposals for all of the Funds except Credit Suisse Commodity Return Strategy Fund and Credit Suisse Trust – Commodity Return Strategy Portfolio. Proxy proposals addressed by the Procedures will be voted in accordance with the Procedures. Proxy proposals addressed by the Procedures that require a case-by-case analysis will be voted in accordance with the vote recommendation of ISS. Proxy proposals not addressed by the Procedures will also be voted in accordance with the vote recommendation of ISS. To the extent that the Proxy Voting Committee proposes to deviate from the Procedures or the ISS vote recommendation, the Committee shall obtain client consent as described below.

5

Credit Suisse investment professionals may submit a written recommendation to the Proxy Voting Committee to vote in a manner inconsistent with the Procedures and/or the recommendation of ISS. Such recommendation will set forth its basis and rationale. In addition, the investment professional must confirm in writing that he/she is not aware of any conflicts of interest concerning the proxy matter or provide a full and complete description of the conflict.

In the event a Portfolio Manager (“PM”) desires to deviate from the stated voting parameters outlined in the Procedures, the PM is required to submit a memo detailing the request and rationale for the deviation to the Chair of the Proxy Voting Committee. The Chair of the Proxy Voting Committee (“Committee”) will convene a meeting where the PM will present their recommendation. In the event an in person or telephonic meeting cannot be organized, the Chair of the Committee will circulate the PM’s request for an exception to the Proxy Voting Committee for consideration.

Should such Procedures exception be approved by the Proxy Voting Committee, the Committee will forward the instructions to ISS for processing and will minute the meeting.

Conflicts

Credit Suisse is the part of the asset management business of Credit Suisse, one of the world’s leading banks. As part of a global, full service investment-bank, broker-dealer, and wealth-management organization, Credit Suisse and its affiliates and personnel may have multiple advisory, transactional, financial, and other interests in securities, instruments, and companies that may be purchased or sold by Credit Suisse for its clients’ accounts. The interests of Credit Suisse and/or its affiliates and personnel may conflict with the interests of Credit Suisse’s clients in connection with any proxy issue. In addition, Credit Suisse may not be able to identify all of the conflicts of interest relating to any proxy matter.

Consent

In each and every instance in which the Proxy Voting Committee favors voting in a manner that is inconsistent with the Procedures or the vote recommendation of ISS (including proxy proposals addressed and not addressed by the Procedures), it shall disclose to the client conflicts of interest information and obtain client consent to vote. Where the client is a Fund, disclosure shall be made to any one director who is not an “interested person,” as that term is defined under the Investment Company Act of 1940, as amended, of the Fund.

6

Recordkeeping

Credit Suisse is required to maintain in an easily accessible place for six years all records relating to proxy voting.

These records include the following:

• a copy of the Procedures;

• a copy of each proxy statement received on behalf of Credit Suisse clients;

• a record of each vote cast on behalf of Credit Suisse clients;

• a copy of all documents created by Credit Suisse personnel that were material to making a decision on a vote or that memorializes the basis for the decision; and

• a copy of each written request by a client for information on how Credit Suisse voted proxies, as well as a copy of any written response.

Credit Suisse reserves the right to maintain certain required proxy records with ISS in accordance with all applicable regulations.

Disclosure

Credit Suisse will describe the Procedures to each client. Upon request, Credit Suisse will provide any client with a copy of the Procedures. Credit Suisse will also disclose to its clients how they can obtain information on their proxy votes.

ISS will capture data necessary for Funds to file Form N-PX on an annual basis concerning their proxy voting record in accordance with applicable law.

A description of the Procedures is contained in each Fund’s Statement of Additional Information the telephone number for more information must be disclosed in each Fund’s Form N-CSR.

Procedures

The Proxy Voting Committee will administer the voting of all client proxies. Credit Suisse has engaged ISS as an independent third party proxy voting service to assist in the voting of client proxies. ISS will coordinate with each client’s custodian to ensure that proxy materials reviewed by the custodians are processed in a timely fashion. ISS will provide Credit Suisse with an analysis of proxy issues and a vote recommendation for proxy proposals. ISS will refer proxies to the Proxy Voting Committee for instructions when the application of the Procedures is not clear. The Proxy Voting Committee will notify ISS of any changes to the Procedures or deviating thereof.

Potential Conflicts of Interest

It is possible that conflicts of interest may arise in connection with the portfolio managers’ management of the Funds’ investments on the one hand and the investments of other accounts on the other. For example, the portfolio managers may have conflicts of interest in allocating management time, resources and investment opportunities among the Funds and other accounts they advise. In addition due to differences in the investment strategies or restrictions between the Funds and the other accounts, the portfolio managers may take action with respect to another account that differs from the action taken with respect to the Funds. Credit Suisse has adopted policies and procedures that are designed to minimize the effects of these conflicts.

If Credit Suisse believes that the purchase or sale of a security is in the best interest of more than one client, it may (but is not obligated to) aggregate the orders to be sold or purchased to seek favorable execution or lower brokerage commissions, to the extent permitted by applicable laws and regulations. Credit Suisse may aggregate orders if all participating client accounts benefit equally (i.e., all receive an average price of the aggregated orders). In the event Credit Suisse aggregates an order for participating accounts, the method of allocation will generally be determined prior to the trade execution. Although no specific method of allocation of transactions (as well as expenses incurred in the transactions) is expected to be used, allocations will be designed to ensure that over time all clients receive fair treatment consistent with Credit Suisse’s fiduciary duty to its clients (including its duty to seek to obtain best execution of client trades). The accounts aggregated may include registered and unregistered investment companies managed by Credit Suisse’s affiliates and accounts in which Credit Suisse’s officers, directors, agents, employees or affiliates own interests. Credit Suisse may not be able to aggregate securities transactions for clients who direct the use of a particular broker-dealer, and the client also may not benefit from any improved execution or lower commissions that may be available for such transactions.

Compensation

Thomas J. Flannery and Wing Chan are compensated for their services by Credit Suisse. Their compensation consists of a fixed base salary and a discretionary bonus that is not tied by formula to the performance of any fund or account. The factors taken into account in determining each of their bonuses includes the Fund’s performance, assets held in the Fund and other accounts managed by each of them, business growth, team work, management, corporate citizenship, etc.

A portion of the bonus may be paid in phantom shares of Credit Suisse Group AG stock as deferred compensation. Phantom shares are shares representing an unsecured right to receive on a particular date a specified number of registered shares subject to certain terms and conditions. A portion of the bonus will receive the notional return of the fund(s) the portfolio manager manages and a portion of the bonus will receive the notional return of a basket of other Credit Suisse funds along the product line of the portfolio manager.

20

Like all employees of Credit Suisse, portfolio managers participate in Credit Suisse Group AG’s profit sharing and 401 (k) plans.

EX-99.(13)(A)(1)

EX-99.CODE ETHICS

EXHIBIT 13(a)(1)

CODE OF ETHICS

CREDIT SUISSE FUNDS

CODE OF ETHICS FOR SENIOR OFFICERS

Preamble

Section 406 of the Sarbanes-Oxley Act of 2002 directs that rules be adopted disclosing whether a company has a code of ethics for senior financial officers. The Securities and Exchange Commission (the “SEC”) has adopted rules requiring annual disclosure of an investment company’s code of ethics applicable to the company’s principal executive as well as principal financial officers, if such a code has been adopted. In response, the above Funds (each a “Fund”, and together the “Funds”) have adopted this Code of Ethics.

Statement of Policy

It is the obligation of the senior officers of the Funds to provide full, fair, timely and comprehensible disclosure—financial and otherwise--to Fund shareholders, regulatory authorities and the general public. In fulfilling that obligation, senior officers must act ethically, honestly and diligently. This Code is intended to enunciate guidelines to be followed by persons who serve the Funds in senior officerships. No Code can address every situation that a senior officer might face; however, as a guiding principle, senior officers should strive to implement the spirit as well as the letter of applicable laws, rules and regulations, and to provide the type of clear and complete disclosure and information Fund shareholders have a right to expect.

The purpose of this Code of Ethics is to promote high standards of ethical conduct by Covered Persons (as defined below) in their capacities as officers of the Funds, to instruct them as to what is considered to be inappropriate and unacceptable conduct or activities for officers and to prohibit such conduct or activities. This Code supplements other policies that the Funds and their adviser have adopted or may adopt in the future with which Fund officers are also required to comply (e.g., code of ethics relating to personal trading and conduct).

Covered Persons

This Code of Ethics applies to those persons appointed by the Fund’s Board of Directors as Chief Executive Officer, President, Chief Financial Officer and Chief Accounting Officer, or persons performing similar functions. It is recognized that each of such persons currently is a full-time employee of Credit Suisse Asset Management LLC (“Credit Suisse”), each Fund’s investment adviser.

Promotion of Honest and Ethical Conduct

In serving as an officer of the Funds, each Covered Person must maintain high standards of honesty and ethical conduct and must encourage his colleagues who provide services to the Funds, whether directly or indirectly, to do the same.

Each Covered Person understands that as an officer of a Fund, he has a duty to act in the best interests of the Fund and its shareholders. The interests of other Credit Suisse clients or Credit Suisse itself or the Covered Person’s personal interests should not be allowed to compromise the Covered Person’s fulfilling his duties as an officer of the Fund. The governing Boards of the Funds recognize that the Covered Persons are also officers or employees of Credit Suisse.

Furthermore, the governing Boards of the Funds recognize that, subject to the Covered Person’s fiduciary duties to the Funds, the Covered Persons will in the normal course of their duties (whether formally for the Funds or for Credit Suisse, or for both) be involved in establishing policies and implementing decisions that will have different effects on Credit Suisse and the Funds. The governing Boards of the Funds recognize that the participation of the Covered Persons in such activities is inherent in the contractual relationship between the Funds and Credit Suisse and/or its affiliates, and is consistent with the expectation of the governing Boards of the performance by the Covered Persons of their duties as officers of the Funds.

If a Covered Person believes that his responsibilities as an officer or employee of Credit Suisse are likely to materially compromise his objectivity or his ability to perform the duties of his role as an officer of the Funds, he should consult with Credit Suisse’s general counsel, the Funds’ chief legal officer or outside counsel, or counsel to the independent Directors/Trustees of the relevant Fund or Funds. Under appropriate circumstances, a Covered Person should also consider whether to present the matter to the Directors/Trustees of the relevant Fund or Funds or a committee thereof.

No Covered Person shall suggest that any person providing, or soliciting to be retained to provide, services to a Fund give a gift or an economic benefit of any kind to him in connection with the person’s retention or the provision of services.

Promotion of Full, Fair, Accurate, Timely and Understandable Disclosure

No Covered Person shall create or further the creation of false or misleading information in any SEC filing or report to Fund shareholders. No Covered Person shall conceal or fail to disclose information within the Covered Person’s possession legally required to be disclosed or necessary to make the disclosure made not misleading.

EX-99.IRANNOTICE

Iran Related Activities Disclosure

Disclosure pursuant to Section 13(r) of the Securities Exchange Act of 1934

During 2019, Credit Suisse AG processed a small number of de minimis payments related to the operation of Iranian diplomatic missions in Switzerland and related to fees for ministerial government functions such as issuing passports and visas. Processing these payments is permitted under Swiss law, and Credit Suisse AG intends to continue processing such payments. Revenues and profits from these activities are not calculated but would be negligible.
