Credit Suisse Floating Rate High Income Fund
Semiannual Investment Adviser's Report
April 30, 2019 (unaudited)

May 23, 2019

Dear Shareholder:

We are pleased to present this Semiannual Report covering the activities of the Credit Suisse Floating Rate High Income Fund (the "Fund") for the six-month period ended April 30, 2019.

Performance Summary
11/1/2018 – 04/30/19

Fund & Benchmark	Performance
Class I1		1.39	%
Class A1,2		1.42	%
Class C1,2		0.90	%
Credit Suisse Leveraged Loan Index3		2.17	%

Performance shown for the Fund's Class A and Class C Shares does not reflect sales charges, which are a maximum of 4.75% and 1.00%, respectively.²

Market Review: A steady period for the asset class

The six-month period ended April 30, 2019 was a positive one for the senior secured loan asset class, with the Credit Suisse Leveraged Loan Index (the "Index"), the Fund's benchmark, returning 2.17% for the period. The discount margin for senior loans, using a three-year average life assumption, tightened 0.14% during the period to +429 basis points. Returns were dominated by coupon clipping, as the price of the Index decreased 0.59 points to finish the period at 97.45%.

Toward the end of 2018, the Federal Reserve initiated a more dovish stance on the Fed Funds rate. Some retail investors who had been attracted to the loan asset class due to its floating rate feature in a rising rate environment, reduced their allocations. As a result, fund flows in the period were -$33.4 billion, highlighted by a -$15.3 billion outflow in December. With much of the "quick money" flowing out during the first three months of the period, outflows have tapered off and averaged just $2.8 billion on a monthly basis from February to April, according to JPMorgan.

Though outflows created pockets of volatility in the leverage loan market, these were somewhat mitigated by continued CLO creation and a light new issue calendar. Gross and net CLO issuance was $91.4 billion and $62.2 billion respectively, while gross and net loan issuance was $136.1 billion and $94.3 billion respectively.

The par-weighted default rate ended the period at 1.29% — as compared to the long-term average rate of 3.00 – 3.50% — signaled stable fundamentals within the asset class.

Returns in the Index were mixed from a quality point-of-view. The split B- and non-rated portions of the Index were the largest contributors to returns, ending the period at 2.89% and 2.80%, respectively. Conversely, the CCC/split CCC and split BB portions lagged, returning -0.92% and 2.23%, respectively.

Strategic Review and Outlook: Remaining positive on fundamentals

For the six-month period ended April 30, 2019, the Fund underperformed its benchmark. Security selection in information technology contributed positively to returns, while energy, financial and consumer durables selections detracted from relative returns. From a rating perspective, security selection in Caa2 and B2 rated positions detracted from relative returns, while B1 added to relative performance.

Leveraged loans have gotten off to a strong start in 2019 amidst the backdrop of a quiet period in primary loan issuance. Following the pivot in sentiment from the Federal Reserve, the rising-rate environment that drew the interest of retail investors in the first nine months of 2018 has reversed — and we expect to see continued outflows from this specific investor base. However, we anticipate only a limited impact to secondary trading levels given both the diminished amount of leveraged loan ownership from the mutual fund client base and the continued demand from CLO ramping.

While broader market risk movements — namely equities and headline risk from tariffs — will have a directional impact looking forward, default rates are expected to continue to be below historical averages.

Senior secured floating rate loans ("Senior Loans") typically hold the most senior position in the issuer's capital structure. Senior Loans are subject to the risk that a court could subordinate a Senior Loan to presently existing or future indebtedness or take other action detrimental to the holders of Senior Loans.

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.

Additional principal risk factors for the Fund include conflict of interest risk, credit risk, foreign securities risk, interest rate risk, liquidity risk, market risk, prepayment risk and valuation risk. Before you invest, please make sure you understand the risks that apply to the Fund. As with any mutual fund, you could lose money over any period of time.

Investments in the Fund are not bank deposits and are not insured or guaranteed by the Federal Deposit Insurance Corporation or any government agency. For a detailed discussion of these and other risks, please refer to the Fund's Prospectus, which should be read carefully before investing.

In addition to historical information, this report contains forward-looking statements, which may concern, among other things, domestic and foreign markets, industry and economic trends and developments and government regulation, and their potential impact on the Fund's investments. These statements are subject to risks and uncertainties and actual trends, developments and regulations in the future, and their impact on the Fund, could be materially different from those projected, anticipated or implied. The Fund has no obligation to update or revise forward-looking statements.

The views of the Fund's management are as of the date of this letter and the Fund holdings described in this document are as of April 30, 2019; 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  Fee waivers and/or expense reimbursements reduce expenses for the Fund, without which performance would be lower. Effective April 22, 2019, the Fund entered into a written contract to limit expenses to 0.70% of the Fund's average daily net assets for Class I shares, 0.95% of the Fund's average daily net assets for Class A shares and 1.70% of the Fund's average daily net assets for Class C shares through at least February 28, 2020. This limit excludes certain expenses, as set forth in the Fund's Prospectus.

²  Total return for the Fund's Class A shares for the reporting period, based on offering price (including maximum sales charge of 4.75%), was (3.39%). Total return for the Fund's Class C shares for the reporting period, based on redemption value including maximum contingent deferred sales charge ("CDSC") of 1.00%, was (0.09%).

Returns represent past performance and include change in share price and reinvestment of dividends and capital gain distributions, if any. Past performance cannot guarantee future results. The current performance of the Fund may be lower or higher than the figures shown. Returns and share price will fluctuate, and redemption value may be more or less than original cost. The performance results do not reflect the deduction of taxes that a shareholder would pay on Fund distributions or the redemption of Fund shares. Performance information current to the most recent month end is available at www.credit-suisse.com/us/funds.

The annual gross expense ratios are 0.79% for Class I shares, 1.04% for Class A shares, and 1.79% for Class C shares. The annual net expense ratios after fee waivers and/or expense reimbursements are 0.70% for Class I shares, 0.95% for Class A shares, and 1.70% for Class C shares.

Information About Your Fund's Expenses

As an investor of the Fund, you incur two types of costs: ongoing expenses and transaction costs. Ongoing expenses include management fees, distribution and service (12b-1) fees and other Fund expenses. Examples of transaction costs include sales charges (loads), redemption fees and account maintenance fees, which are not shown in this section and which would result in higher total expenses. The following table is intended to help you understand your ongoing expenses of investing in the Fund and to help you compare these expenses with the ongoing expenses of investing in other mutual funds. The table is based on an investment of $1,000 made at the beginning of the six months ended April 30, 2019.

The table illustrates your Fund's expenses in two ways:

•  Actual Fund Return. This helps you estimate the actual dollar amount of ongoing expenses paid on a $1,000 investment in the Fund using the Fund's actual return during the period. To estimate the expenses you paid over the period, simply divide your account value by $1,000 (for example, an $8,600 account value divided by $1,000 = 8.6), then multiply the result by the number in the "Expenses Paid per $1,000" line.

•  Hypothetical 5% Fund Return. This helps you to compare the Fund's ongoing expenses with those of other mutual funds using the Fund's actual expense ratio and a hypothetical rate of return of 5% per year before expenses. Examples using a 5% hypothetical fund return may be found in the shareholder reports of other mutual funds. The hypothetical account values and expenses may not be used to estimate the actual ending account balance or expenses you paid for the period.

Please note that the expenses shown in these tables are meant to highlight your ongoing expenses only and do not reflect any transaction costs, such as sales charges (loads) or redemption fees. If these transaction costs had been included, your costs would have been higher. The "Expenses Paid per $1,000" line of the tables is useful in comparing ongoing expenses only and will not help you determine the relative total expenses of owning different funds.

	Class I			Class A			Class C
Annualized Expense Ratios*		0.70	%		0.95	%		1.70	%

*  Expenses are equal to the Fund's annualized expense ratio for each share class, multiplied by the average account value over the period, multiplied by 181/365 to reflect the one-half year period.

  The "Expenses Paid per $1,000" and the "Annualized Expense Ratios" in the tables are based on actual expenses paid by the Fund during the period, net of fee waivers and/or actual expense reimbursements, if applicable. If those fee waivers and/or expense reimbursements had not been in effect, the Fund's actual expenses would have been higher. Expenses do not reflect additional charges and expenses that are, or may be, imposed under the variable contracts or plans. Such charges and expenses are described in the prospectus of the insurance company separate account or in the plan documents or other informational materials supplied by plan sponsors. The Fund's expenses should be considered with these charges and expenses in evaluating the overall cost of investing in the separate account.

For more information, please refer to the Fund's Prospectus.

Credit Suisse Floating Rate High Income Fund
Notes to Financial Statements
April 30, 2019 (unaudited)

Note 1. Organization

Credit Suisse Floating Rate High Income Fund (the "Fund"), a series of Credit Suisse Opportunity Funds (the "Trust"), a Delaware statutory trust, is registered under the Investment Company Act of 1940, as amended (the "1940 Act"), as a diversified open-end management investment company that seeks to provide a high level of current income and, secondarily, capital appreciation. The Trust was organized under the laws of the State of Delaware as a business trust on May 31, 1995.

The Fund offers three classes of shares: Class I shares, Class A shares and Class C shares. Each class of shares represents an equal pro rata interest in the Fund, except the share classes bear different expenses. Class A shares are sold subject to a front-end sales charge of up to 4.75%. Class C shares are sold subject to a CDSC of 1.00% if the shares are redeemed within the first year of purchase. Class I shares are sold without a sales charge. Class B shares were terminated on December 15, 2017 and are no longer offered.

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's ("FASB") Accounting Standard 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

Note 2. Significant Accounting Policies (continued)

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 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.

Note 2. Significant Accounting Policies (continued)

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

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

•  Level 1  –  quoted prices in active markets for identical investments

•  Level 2  –  other significant observable inputs (including quoted prices for similar investments, interest rates, prepayment speeds, credit risk, etc.)

•  Level 3  –  significant unobservable inputs (including the Fund's own assumptions in determining the fair value of investments)

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

The following is a summary of the inputs used as of April 30, 2019 in valuing the Fund's assets and liabilities carried at 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

37

Credit Suisse Floating Rate High Income Fund
Notes to Financial Statements (continued)

Note 2. Significant Accounting Policies (continued)

price and extent of public trading in similar securities of the issuer or of comparable companies; or (v) a probability and time value adjusted analysis of contractual term. Where available and appropriate, multiple valuation methodologies are applied to confirm fair value. To the extent that valuation is based on models or inputs that are less observable or unobservable in the market, determining fair value requires more judgment. Because of the inherent uncertainty of valuation, those estimated values may be materially higher or lower than the values that would have been used had a ready market for the investments existed. Accordingly, the degree of judgment exercised by the Fund in determining fair value is greatest for investments categorized in Level 3. In some circumstances, the inputs used to measure fair value might be categorized within different levels of the fair value hierarchy. In those instances, the fair value measurement is categorized in its entirety in the fair value hierarchy based on the least observable input that is significant to the fair value measurement. Additionally, changes in the market environment and other events that may occur over the life of the investments may cause the gains or losses ultimately realized on these investments to be different from the valuations used at the date of these financial statements.

For the six months ended April 30, 2019, $1,744,750 was transferred from Level 3 to Level 1 as a result of availability of a pricing source supported by quoted prices in active markets, $141,804,974 was transferred from Level 2 to Level 3 due to a lack of pricing source supported by observable inputs and $59,312,759 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. For the six months ended April 30, 2019, the Fund's derivatives did not qualify for hedge accounting as they are held at fair value.

The following table presents the fair value and the location of derivatives within the Statement of Assets and Liabilities at April 30, 2019 and the effect of these derivatives on the Statement of Operations for the six months ended April 30, 2019.

For the six months ended April 30, 2019, the Fund held an average monthly value on a net basis of $364,864,014 in forward foreign currency contracts.

The Fund is a party to International Swap and Derivatives Association, Inc. ("ISDA") Master Agreements ("Master Agreements") with certain counterparties that govern over-the-counter derivative (including Total Return, Credit Default and Interest Rate Swaps) and foreign exchange contracts entered into by the Fund. The Master Agreements may contain provisions regarding, among other things, the parties' general obligations, representations, agreements, collateral requirements, events of default and early termination. Termination events applicable to the Fund may occur upon a decline in the Fund's net assets below a specified threshold over a certain period of time.

The following table presents by counterparty the Fund's derivative assets, net of related collateral held by the Fund, at April 30, 2019:

Credit Suisse Floating Rate High Income Fund
Notes to Financial Statements (continued)
April 30, 2019 (unaudited)

Note 2. Significant Accounting Policies (continued)

C) FOREIGN CURRENCY TRANSACTIONS — The books and records of the Fund are maintained in U.S. dollars. Transactions denominated in foreign currencies are recorded at the current prevailing exchange rates. 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. Certain expenses are class-specific expenses, vary by class and are charged only to that class. Income, expenses (excluding class-specific expenses) and realized/unrealized gains/losses are allocated proportionately to each class of shares based upon the relative net asset value of the outstanding shares of that class. 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 — Dividends from net investment income, if any, are declared daily and paid monthly. Distributions of net realized capital gains, if any, are declared and paid at least

40

Credit Suisse Floating Rate High Income Fund
Notes to Financial Statements (continued)
April 30, 2019 (unaudited)

Note 2. Significant Accounting Policies (continued)

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.

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) 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

41

Credit Suisse Floating Rate High Income Fund
Notes to Financial Statements (continued)
April 30, 2019 (unaudited)

Note 2. Significant Accounting Policies (continued)

forward exchange rate of the underlying currencies and unrealized gain/loss is recorded daily. On the settlement date of the forward currency contract, the Fund records a realized gain or loss equal to the difference between the value of the contract at the time it was opened and the value of the contract at the time it was closed. Certain risks may arise upon entering into forward currency contracts from the potential inability of counterparties to meet the terms of their contracts. The maximum counterparty credit risk to the Fund is measured by the unrealized gain on appreciated contracts. Additionally, when utilizing forward currency contracts to hedge, the Fund forgoes the opportunity to profit from favorable exchange rate movements during the term of the contract. The Fund's open forward currency contracts at April 30, 2019 are disclosed in the Schedule of Investments.

I) UNFUNDED LOAN COMMITMENTS — The Fund enters into certain agreements, all or a portion of which may be unfunded. The Fund is obligated to fund these loan commitments at the borrowers' discretion. Funded and unfunded portions of credit agreements are presented in the Schedule of Investments. As of April 30, 2019, unfunded commitments were as follows:

Borrower	Maturity	Rate		Unfunded Commitment
Bulldog Purchaser Inc.	09/04/26		3.875	$	249,515
Bulldog Purchaser Inc.	09/05/25		3.750	$	465,392

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.

J) SECURITIES LENDING — The initial collateral received by the Fund is required to have a value of at least 102% of the market value of domestic securities on loan (including any accrued interest thereon) and 105% of the market value of foreign securities on loan (including any accrued interest thereon). The collateral is maintained thereafter at a value equal to at least 102% of the current market value of the securities on loan. The market value of loaned securities is determined at the close of each business day of the Fund and any additional required collateral is delivered to the Fund, or excess collateral returned by the Fund, on the next business day. Cash collateral received by the Fund in connection with securities lending activity may be pooled together with cash collateral for other funds/portfolios advised by Credit Suisse and may be invested in a variety of investments, including funds advised by SSB, the Fund's securities lending agent, or money market

42

Note 2. Significant Accounting Policies (continued)

instruments. However, in the event of default or bankruptcy by the other party to the agreement, realization and/or retention of the collateral may be subject to legal proceedings.

SSB has been engaged by the Fund to act as the Fund's securities lending agent. As of April 30, 2019, the Fund had investment securities on loan with a fair value of $8,885,338. Collateral received for securities loaned and a related liability of $9,013,838 are presented gross in the Statement of Assets and Liabilities. The collateral for securities loaned is valued consistently to the other investments held by the Fund and is included in Level 2 of the fair value hierarchy. As of April 30, 2019, the value of the related collateral exceeded the value of the securities loaned.

The Fund's securities lending arrangement provides that the Fund and SSB will share the net income earned from securities lending activities. Securities lending income is accrued as earned. During the six months ended April 30, 2019, total earnings from the Fund's investment in cash collateral received in connection with securities lending arrangements was $113,915, of which $65,551 was rebated to borrowers (brokers). The Fund retained $36,365 in income from the cash collateral investment, and SSB, as lending agent, was paid $11,999.

K) OTHER — The high yield, fixed income securities in which the Fund invests will primarily consist of senior secured floating rate loans ("Senior Loans") issued by non-investment grade companies. Senior Loans are typically secured by specific collateral of the issuer and hold the most senior position in the issuer's capital structure. The interest rate on Senior Loans is periodically adjusted to a recognized base rate, typically the London Interbank Offered Rate ("LIBOR"). While these characteristics may reduce interest rate risk and mitigate losses in the event of borrower default, the Senior Loans in which the Fund invests have below investment grade credit ratings and thereby are considered speculative because of the significant credit risk of their issuers.

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.

43

Note 2. Significant Accounting Policies (continued)

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

L) NEW ACCOUNTING PRONOUNCEMENTS — In March 2017, the FASB issued Accounting Standards Update 2017-08, Receivables — Nonrefundable Fees and Other Costs (Subtopic 310-20): Premium Amortization On Purchased Callable Debt Securities ("ASU 2017-08"). The update shortens the amortization period for the premium on certain purchased callable debt securities to the earliest call date. ASU 2017-08 will be effective for annual periods beginning after December 15, 2018. Management is currently assessing the potential impact of these changes to future financial statements.

Also, 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").

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

daily net assets for Class C shares. The Fund is authorized to reimburse Credit Suisse for management fees previously limited and/or for expenses previously reimbursed by Credit Suisse, provided, however, that any reimbursements must be paid at a date not more than thirty-six months following the applicable month during which such fees were limited or expenses were reimbursed by Credit Suisse and the reimbursements do not cause the Fund to exceed the applicable expense limitation at the time the fees are recouped. Prior to April 22, 2019, these expense limitations were voluntary.

The amounts waived and reimbursed by Credit Suisse, which are available for potential future recoupment by Credit Suisse, and the expiration schedule at April 30, 2019 are as follows:

	Fee waivers/ expense reimbursements subject to recoupment		Expires October 31, 2022
Class I	$	78,236	$	78,236

Class C		3,234		3,234
Totals	$	88,599	$	88,599

For its co-administrative services, SSB receives a fee, exclusive of out-of-pocket expenses, calculated in total for all the Credit Suisse funds/portfolios co-administered by SSB and allocated based upon the relative average net assets of each fund/portfolio, subject to an annual minimum fee. For the six months ended April 30, 2019, co-administrative services fees earned by SSB (including out-of-pocket expenses) with respect to the Fund were $244,241.

Credit Suisse Securities (USA) LLC ("CSSU"), an affiliate of Credit Suisse, serves as the distributor of the Fund's shares. Pursuant to a distribution plan adopted by the Fund pursuant to Rule 12b-1 under the 1940 Act, CSSU receives fees for its distribution services. These fees are calculated at an annual rate of 0.25% of the average daily net assets of the Class A shares. For the Class B and Class C shares, the fee is calculated at an annual rate of 1.00% of the average daily net assets. For the six months ended April 30, 2019, the Fund paid Rule 12b-1 distribution fees of $312,836 for Class A shares and $539,177 for Class C shares. Class I shares are not subject to Rule 12b-1 distribution fees.

Certain brokers, dealers and financial representatives provide transfer agent-related services to the Fund and receive compensation from the Fund. For the six months ended April 30, 2019, the Fund paid $2,001,039, which is included within transfer agent fees.

The Fund, together with other funds/portfolios advised by Credit Suisse (collectively, the "Participating Funds"), participates in a committed, unsecured line of credit facility ("Credit Facility"), with SSB in an aggregated amount of $250 million for temporary or emergency purposes on a first-come, first-served basis. Under the terms of the Credit Facility, the Participating Funds pay an aggregate commitment fee on the average unused amount of the Credit Facility, which is allocated among the Participating Funds in such manner as is determined by the governing Boards of the Participating Funds. In addition, the Participating Funds pay interest on borrowings at either the Overnight Federal Funds rate or the Overnight LIBOR rate plus a spread. At April 30, 2019 and during the six months ended April 30, 2019, the Fund had no borrowings outstanding under the Credit Facility. Additionally, the Fund is party to a joint uncommitted line of credit facility with SSB. For the six months ended April 30, 2019, the line was not drawn upon and no fees were incurred.

Note 5. Purchases and Sales of Securities

Note 6. Capital Share Transactions (continued)

On April 30, 2019, the number of shareholders that held 5% or more of the outstanding shares of each class of the Fund was as follows:

	Number of Shareholders		Approximate Percentage of Outstanding Shares
Class I		5		52	%
Class A		4		64	%
Class C		4		68	%

The Fund's performance may be negatively impacted in the event one or more of the Fund's greater than 5% shareholders were to redeem at a given time. Some of the shareholders are omnibus accounts, which hold shares on behalf of individual shareholders.

Note 7. Contingencies

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

Credit Suisse Floating Rate High Income Fund
Board Approval of Investment Management Agreement (unaudited)

In approving the amended and restated investment management agreement (the "Investment Management Agreement") for the Credit Suisse Floating Rate High Income Fund (the "Fund"), a series of Credit Suisse Opportunity Funds (the "Trust"), the Board of Trustees of the Trust (the "Board"), including all of the trustees who are not "interested persons" of the Trust as defined in the Investment Company Act of 1940 (the "Independent Trustees"), at a Special Telephonic Meeting held on November 7, 2018 where the Board discussed information and materials previously provided to them in connection with the renewal of the Investment Management Agreement, and at an in-person meeting held on November 12 and 13, 2018, considered the following factors:

Investment Management Fee Rates and Expenses

The Board reviewed and considered the contractual management fee rate of 0.79% of the Fund's average daily net assets less than or equal to $100 million and 0.59% of the Fund's average daily net assets greater than $100 million (the "Contractual Management Fee") for the Fund in light of the extent and quality of the management services provided by Credit Suisse Asset Management, LLC ("Credit Suisse"), the Fund's investment manager. The Board also reviewed and considered the voluntary fee waivers currently in place for the Fund and considered the actual fee rate of 0.54% paid by the Fund after taking waivers and breakpoints into account (the "Net Management Fee"). The Board acknowledged that voluntary fee waivers could be discontinued at any time but had received assurances that such waivers would remain in place over the next year.

Additionally, the Board received and considered information comparing the Fund's Contractual Management Fee, Net Management Fee and the Fund's overall expenses with those of funds in both the relevant expense group ("Expense Group") and universe of funds ("Expense Universe") provided by Broadridge, an independent provider of investment company data. The Board noted that the Fund's Contractual Management Fee, Net Management Fee and overall expenses were within the range of its peers as presented in the Broadridge report. The Board was provided with a description of the methodology used to arrive at the funds included in the Expense Group and the Expense Universe.

Nature, Extent and Quality of the Services under the Management Agreement

The Board received and considered information regarding the nature, extent and quality of services provided to the Fund by Credit Suisse under the

49

Credit Suisse Floating Rate High Income Fund
Board Approval of Investment Management Agreement (unaudited) (continued)

Investment Management Agreement. The Board also noted information received at regular meetings throughout the year related to the services rendered by Credit Suisse which, in addition to portfolio management and investment management services set forth in the Investment Management Agreement, also included credit analysis and research, supervising the day to day operations of the Fund's non-advisory functions which include accounting, administration, custody, transfer agent and other applicable third party service providers, overseeing and facilitating audits, overseeing the Fund's credit facility and supervising and/or preparing applicable Fund filings, disclosures and shareholder reports. The Board noted that the extensive investment management services provided by Credit Suisse included broad supervisory responsibility and oversight over other service providers to the Fund. The Board also considered Credit Suisse's compliance program with respect to the Fund. The Board noted that Credit Suisse reports to the Board about portfolio management and compliance matters on a periodic basis. The Board reviewed background information about Credit Suisse including its Form ADV Part 2 — Disclosure Brochure and Brochure Supplement. The Board considered the background and experience of Credit Suisse's senior management and the expertise of, and the amount of attention given to the Fund by, senior personnel of Credit Suisse. In addition, the Board reviewed the qualifications, backgrounds and responsibilities of the portfolio management team primarily responsible for the day-to-day portfolio management of the Fund and the extent of the resources devoted to research and analysis of actual and potential investments, as well as the resources provided to them. The Board evaluated the ability of Credit Suisse, based on its resources, reputation and other attributes, to attract and retain qualified investment professionals including research, advisory, and supervisory personnel. The Board also received and considered information about the nature, extent and quality of services and fee rates offered to other Credit Suisse clients for comparable services. The Board acknowledged Credit Suisse's representation that the services provided to the Fund are more extensive than the services provided in connection with other types of accounts, such as separate accounts, offered by Credit Suisse and the services are also more extensive from those offered and provided to a sub-advised fund. The Board also considered that the services provided by Credit Suisse have expanded over time as a result of regulatory and other developments.

50

Credit Suisse Floating Rate High Income Fund
Board Approval of Investment Management Agreement (unaudited) (continued)

Fund Performance

The Board received and considered performance results of the Fund over the previous year as well as over longer time periods, along with comparisons both to the relevant performance group ("Performance Group") and universe of funds ("Performance Universe") for the Fund. The Board was provided with a description of the methodology used to arrive at the funds included in the Performance Group and the Performance Universe. The Board noted that the Fund performed in line with its Performance Universe for the one-year period reported, and slightly outperformed or outperformed its Performance Universe over various longer investment periods reported. The Board also considered the investment performance of the Fund over various investment periods relative to its stated objectives.

Credit Suisse Profitability

The Board received and considered a profitability analysis of Credit Suisse based on the fees payable under the Investment Management Agreement for the Fund, including any fee waivers, as well as other relationships between the Fund on the one hand and Credit Suisse affiliates on the other. The Board deliberations also reflected Credit Suisse's methodology for allocating costs to the Fund, recognizing that cost allocation methodologies are inherently subjective. The Board also received net profitability information for the other funds in the Credit Suisse family of funds, which include both open-end and closed-end funds. The Board also reviewed Credit Suisse's profit margin as reflected in the profitability analysis and reviewed information regarding potential economies of scale (as discussed below), as well as reviewing profitability in light of appropriate court cases and the services rendered to the Fund.

Economies of Scale

The Board considered information regarding whether there have been economies of scale with respect to the management of the Fund, whether the Fund has appropriately benefited from any economies of scale, and whether there is potential for realization of any further economies of scale. The Board noted that the Fund's Contractual Management Fee had breakpoints that would allow investors to benefit directly in the form of lower fees as Fund assets grow. The Board also noted the voluntary expense limitation currently in place between the Fund and Credit Suisse. The Board received information

51

Credit Suisse Floating Rate High Income Fund
Board Approval of Investment Management Agreement (unaudited) (continued)

regarding Credit Suisse's historical profitability, including Credit Suisse's costs in providing services.

Other Benefits to Credit Suisse

The Board considered other benefits received by Credit Suisse and its affiliates as a result of their relationship with the Fund. Such benefits include, among others, benefits potentially derived from an increase in Credit Suisse's businesses as a result of its relationship with the Fund (such as the ability to market to shareholders other financial products offered by Credit Suisse and its affiliates) and the fees paid to an affiliate of Credit Suisse for distribution services.

The Board considered the standards applied in seeking best execution and their policies and practices regarding soft dollars and reviewed Credit Suisse's method for allocating portfolio investment opportunities among its advisory clients.

Other Factors and Broader Review

As discussed above, the Board reviewed detailed materials received from Credit Suisse as part of the annual approval process. The Board also reviews and assesses the quality of the services that the Fund receives throughout the year. In this regard, the Board reviews reports of Credit Suisse at least quarterly, which include, among other things, detailed portfolio and market reviews, detailed fund performance reports and Credit Suisse's compliance procedures.

Conclusions

In selecting Credit Suisse, and approving the renewal of the Investment Management Agreement and the investment management fee under such agreement, the Board concluded that:

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

•  The Board was satisfied with the nature, extent and quality of the investment management services provided to the Fund by Credit Suisse and that, based on dialogue with management and counsel, the services provided by Credit Suisse under the Investment Management Agreement

52

Credit Suisse Floating Rate High Income Fund
Board Approval of Investment Management Agreement (unaudited) (continued)

are typical of, and consistent with, those provided to similar mutual funds by other investment managers.

•  In light of the costs of providing investment management and other services to the Fund and Credit Suisse's ongoing commitment to the Fund and willingness to waive fees, Credit Suisse's net profitability based on fees payable under the Investment Management Agreement, as well as other ancillary benefits that Credit Suisse and its affiliates received, were considered reasonable.

•  In light of the information received and considered by the Board, the Fund's current fee structure was considered reasonable.

No single factor reviewed by the Board was identified by the Board as the principal factor in determining whether to approve the renewal of the Investment Management Agreement. The Independent Trustees were advised by separate independent legal counsel throughout the process.

May 23, 2019

Dear Shareholder:

We are pleased to present this Semiannual Report covering the activities of the Credit Suisse Managed Futures Strategy Fund (the "Fund") for the six-month period ended April 30, 2019.

Performance Summary
11/1/18 – 04/30/19

Fund & Benchmark	Performance
Class I1		2.35	%
Class A1,2		2.27	%
Class C1,2		1.94	%
Credit Suisse Managed Futures Liquid Index3		2.38	%

Performance shown for the Fund's Class A and Class C Shares does not reflect sales charges, which are a maximum of 5.25% and 1.00%, respectively. ²

Market Review: An interesting period for managed futures

The six-month period ended April 30, 2019 was a positive one for managed futures, with the Credit Suisse Managed Futures Hedge Fund Index gaining 5.77% and the Credit Suisse Managed Futures Liquid Index, the Fund's benchmark, returning 2.38%.

Equity markets made gains in the first quarter of 2019, rebounding from a weak end to 2018, as concerns over the China-US trade dispute eased and major central banks grew more accommodative. The central bank easing also helped Eurozone equities to recover. Worries over economic growth, however, lingered throughout the latter part of the period.

U.S. 10-year Treasury yields fell in the first quarter of 2019 to reach their lowest level since late 2017. Additionally, as a sign of growing caution around economic growth, the three-month Treasury bill yield rose higher than that of 10-year bonds in March.

Commodities had their best quarter in three years, with the Bloomberg Commodity Index making gains as concerns over Crude oil supplies kept demand relatively steady.

Strategic Review and Outlook: Performance through a unique period

In general, the managed futures strategy is designed to profit from both upward and downward trending markets across several asset classes, including commodities, bonds, equities and currencies.

1

Credit Suisse Managed Futures Strategy Fund
Semiannual Investment Adviser's Report (continued)
April 30, 2019 (unaudited)

For the six-month period ended April 30, 2019, the Fund underperformed the benchmark. Fixed income positions contributed positively to Fund performance, as the dovish tone adopted by central banks pushed global yields down, generating profits from long positions. Following the market turmoil at the end of 2018 that caused a flight to safety, the program entered Q1 2019 with a long bias. Despite the recovery of global markets, yields remained suppressed with weaker economic data signals.

Equity positions, which made positive gains during Q4 2018, were the largest detractors from Fund performance over Q1 2019. The initial January reversal in equity markets created losses in short positions that had scaled with the magnitude of last year's sell-off. As the market recovery gained momentum, the program began paring these short exposures throughout January. The persistence and magnitude of the upward trend reversal caused the program to adopt long positions across underlying markets.

Currencies were the second largest detractor from performance over Q1 2019. The established upward trend in the U.S. Dollar remained above short, medium and longer-term signals at the end of 2018, leading to consensus long positioning across markets and time horizons at the beginning of Q1 2019. Long exposure against the Canadian Dollar was the largest contributor to performance in Q4 2018, as the currency's underperformance gathered momentum in sympathy with the steep decline in oil prices. However, as the upward U.S. Dollar trend subsided, consensus long positions hurt performance.

Commodities also detracted from Fund performance during Q4 2018 and Q1 2019. The reversals in energy, industrial and precious metals markets were primarily responsible for losses in Q1 2019. Relief from concerns over the global growth outlook stoked the upward reversal of growth-sensitive energy and industrial metal commodities, which incurred losses on short positions.

We continue to believe that the unique return profile of managed futures may appeal to investors searching for meaningful portfolio diversifiers that may help mitigate risk and provide uncorrelated returns.

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

instruments may subject the Fund to greater volatility than investments in traditional securities, particularly in investments involving leverage.

The use of alternative assets and strategies entails substantial risks, including risk of loss of principal, commodity exposure risks, credit risk, currency risk, derivatives risk, equity exposure risk, exchange-traded notes risk, fixed income risk, foreign securities risk, forwards risk, futures contracts risk, interest rate risk, leveraging risk, market risk, non-diversified status, options risk, portfolio turnover risk, repurchase agreements risk, short position risk, speculative exposure risk, structured note risk, subsidiary risk, swap agreements risk, tax risk and U.S. government securities risk. For a detailed discussion of these and other risks, please refer to the Fund's Prospectus, which should be read carefully before investing.

In addition to historical information, this report contains forward-looking statements, which may concern, among other things, domestic and foreign markets, industry and economic trends and developments and government regulation and their potential impact on the Fund's investments. These statements are subject to risks and uncertainties and actual trends, developments and regulations in the future, and their impact on the Fund, could be materially different from those projected, anticipated or implied. The Fund has no obligation to update or revise forward-looking statements.

The views of the Fund's management are as of the date of this letter and the Fund holdings described in this document are as of April 30, 2019; 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  Fee waivers and/or expense reimbursements reduce expenses for the Fund, without which performance would be lower. The Fund has entered into a written contract limiting operating expenses to 1.30% of the Fund's average daily net assets for Class I shares, 1.55% of the Fund's average daily net assets for Class A shares and 2.30% of the Fund's average daily net assets for Class C shares at least through February 28, 2020. This limit excludes certain expenses, as set forth in the Fund's Prospectus.

²  Total return for the Fund's Class A shares for the reporting period, based on offering price (including maximum sales charge of 5.25%), was (3.13)%. Total return for the Fund's Class C shares for the reporting period, based on redemption value including maximum contingent deferred sales charge ("CDSC") of 1.00%, was 0.94%.

³  The Credit Suisse Managed Futures Liquid Index is a broadly diversified futures index currently composed of 14 futures contracts and 4 commodity indices which provide exposure to the asset classes. The Index uses a proprietary quantitative methodology which seeks to identify price trends in each of the asset classes over a variety of time horizons. Components of the Index, which may change from time to time, are positioned either long or short based on the price trends within the asset classes determined using the Index's quantitative methodology. The Index does not have transaction costs and investors may not directly invest in the Index.

Information About Your Fund's Expenses

As an investor of the Fund, you incur two types of costs: ongoing expenses and transaction costs. Ongoing expenses include management fees, distribution and service (12b-1) fees and other Fund expenses. Examples of transaction costs include sales charges (loads), redemption fees and account maintenance fees, which are not shown in this section and which would result in higher total expenses. The following table is intended to help you understand your ongoing expenses of investing in the Fund and to help you compare these expenses with the ongoing expenses of investing in other mutual funds. The table is based on an investment of $1,000 made at the beginning of the six months ended April 30, 2019.

The table illustrates your Fund's expenses in two ways:

•  Actual Fund Return. This helps you estimate the actual dollar amount of ongoing expenses paid on a $1,000 investment in the Fund using the Fund's actual return during the period. To estimate the expenses you paid over the period, simply divide your account value by $1,000 (for example, an $8,600 account value divided by $1,000 = 8.6), then multiply the result by the number in the "Expenses Paid per $1,000" line.

•  Hypothetical 5% Fund Return. This helps you to compare the Fund's ongoing expenses with those of other mutual funds using the Fund's actual expense ratio and a hypothetical rate of return of 5% per year before expenses. Examples using a 5% hypothetical fund return may be found in the shareholder reports of other mutual funds. The hypothetical account values and expenses may not be used to estimate the actual ending account balance or expenses you paid for the period.

Please note that the expenses shown in these tables are meant to highlight your ongoing expenses only and do not reflect any transaction costs, such as sales charges (loads) or redemption fees. If these transaction costs had been included, your costs would have been higher. The "Expenses Paid per $1,000" line of the tables is useful in comparing ongoing expenses only and will not help you determine the relative total expenses of owning different funds.

*  Expenses are equal to the Fund's annualized expense ratio for each share class, multiplied by the average account value over the period, multiplied by 181/365 to reflect the one-half year period.

  The "Expenses Paid per $1,000" and the "Annualized Expense Ratios" in the tables are based on actual expenses paid by the Fund during the period, net of fee waivers and/or actual expense reimbursements, if applicable. If those fee waivers and/or expense reimbursements had not been in effect, the Fund's actual expenses would have been higher. Expenses do not reflect additional charges and expenses that are, or may be, imposed under the variable contracts or plans. Such charges and expenses are described in the prospectus of the insurance company separate account or in the plan documents or other informational materials supplied by plan sponsors. The Fund's expenses should be considered with these charges and expenses in evaluating the overall cost of investing in the separate account.

For more information, please refer to the Fund's Prospectus.

Note 1. Organization

Credit Suisse Managed Futures Strategy Fund (the "Fund"), a series of Credit Suisse Opportunity Funds (the "Trust"), a Delaware statutory trust, is registered under the Investment Company Act of 1940, as amended (the "1940 Act"), as a non-diversified open-end management investment company that seeks to achieve an investment results that correspond generally to the risk and return patterns of managed futures funds. The Trust was organized under the laws of the State of Delaware as a business trust on May 31, 1995.

Credit Suisse Asset Management, LLC ("Credit Suisse"), the investment adviser to the Fund, is registered as an investment adviser with the Securities and Exchange Commission and as a Commodity Pool Operator with the Commodity Futures Trading Commission. The Fund seeks to achieve its investment objective by investing directly and/or indirectly through the Credit Suisse Cayman Managed Futures Strategy Fund, Ltd. (the "Subsidiary"), a wholly-owned subsidiary of the Fund organized under the laws of the Cayman Islands, in a combination of securities and derivative instruments. The Subsidiary invests in commodity-linked derivative instruments, such as swaps and futures, as well as other types of futures, swaps and options. The Subsidiary may also invest in debt securities, some of which are intended to serve as margin or collateral for the Subsidiary's derivatives positions.

The Subsidiary is managed by the same portfolio managers that manage the Fund and the accompanying financial statements reflect the financial position of the Fund and the Subsidiary and the results of operations on a consolidated basis. The consolidated financial statements include portfolio holdings of the Fund and the Subsidiary and all intercompany transactions and balances have been eliminated. The Fund may invest up to 25% of its total assets in the Subsidiary. As of April 30, 2019, the Fund held $13,467,443 in the Subsidiary, representing 5.2% of the Fund's consolidated net assets. For the six months ended April 30, 2019, the net realized gain on securities and other financial instruments held in the Subsidiary was $1,507,791.

Subsequent references to the Fund within the Notes to Consolidated Financial Statements collectively refer to the Fund and the Subsidiary.

The Fund offers three classes of shares: Class I shares, Class A shares and Class C shares. Each class of shares represents an equal pro rata interest in the Fund, except the share classes bear different expenses. Class A shares are sold subject to a front-end sales charge of up to 5.25%. Class C shares are sold subject to a contingent deferred sales charge ("CDSC") of 1.00% if the shares are redeemed within the first year of purchase. Class I shares are sold without a sales charge.

Note 2. Significant Accounting Policies

The following is a summary of significant accounting policies followed by the Fund in the preparation of its consolidated financial statements. The policies are in accordance with generally accepted accounting principles in the United States of America ("GAAP"). The preparation of consolidated financial statements requires management to make estimates and assumptions that affect the reported amounts and disclosures in the consolidated 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 Boards's ("FASB") Accounting Standards Codification ("ASC") Topic 946 — Financial Services — Investment Companies.

A) SECURITY VALUATION — The Board of Trustees (the "Board") is responsible for the Fund's 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

16

Credit Suisse Managed Futures Strategy Fund
Notes to Consolidated Financial Statements (continued)

Note 2. Significant Accounting Policies (continued)

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 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.

*  Other financial instruments include unrealized appreciation (depreciation) on futures and swap contracts.

**  Value includes any premium paid or received with respect to swap contracts, if applicable.

For the six months ended April 30, 2019, there were no transfers among Level 1, Level 2 and Level 3. 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. For the six months ended April 30, 2019, the Fund's derivatives did not qualify for hedge accounting as they are held at fair value.

The following table presents the fair value and the location of derivatives within the Consolidated Statement of Assets and Liabilities at April 30, 2019 and the effect of these derivatives on the Consolidated Statement of Operations for the six months ended April 30, 2019.

Note 2. Significant Accounting Policies (continued)

The notional amount of futures contracts and swap contracts open at April 30, 2019 is reflected in the Consolidated Schedule of Investments. For the six months ended April 30, 2019, the Fund held average monthly notional values on a net basis of $494,313,234, $319,194,169 and $70,910,684 in long futures contracts, short futures contracts and swap contracts, respectively.

The Fund is a party to International Swap and Derivatives Association, Inc. ("ISDA") Master Agreements ("Master Agreements") with certain counterparties that govern over-the-counter derivative (including Total Return, Credit Default and Interest Rate Swaps) and foreign exchange contracts entered into by the Fund. The Master Agreements may contain provisions regarding, among other things, the parties' general obligations, representations, agreements, collateral requirements, events of default and early termination. Termination events applicable to the Fund may occur upon a decline in the Fund's net assets below a specified threshold over a certain period of time.

The following table presents by counterparty the Fund's derivative assets, net of related collateral held by the Fund, at April 30, 2019:

Counterparty	Gross Amount of Derivative Assets Presented in the Consolidated Statement of Assets and Liabilities(a)		Financial Instruments and Derivatives Available for Offset			Non-Cash Collateral Received		Cash Collateral Received		Net Amount of Derivative Assets
Goldman Sachs	$	2,030,988	$	(114,177	)	$	—	$	—	$	1,916,811

^(a)  Swap contracts are included.

C) 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. Certain expenses are class-specific expenses, vary by class and are charged only to that class. Income,

19

Credit Suisse Managed Futures Strategy Fund
Notes to Consolidated Financial Statements (continued)
April 30, 2019 (unaudited)

Note 2. Significant Accounting Policies (continued)

expenses (excluding class-specific expenses) and realized/unrealized gains/losses are allocated proportionately to each class of shares based upon the relative net asset value of the outstanding shares of that class. 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.

D) DIVIDENDS AND DISTRIBUTIONS TO SHAREHOLDERS — Dividends from net investment income, if any, are declared and paid quarterly. 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.

E) 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 Internal Revenue Service ("IRS") has issued a ruling that income realized from certain types of commodity-linked derivatives would not be Qualifying Income. As a result, the Fund's ability to realize income from investments in such commodity-linked derivatives as part of its investment strategy would be limited to a maximum of 10% of its gross income. The IRS has issued private letter rulings to registered investment companies concluding that income derived from their investment in a wholly-owned subsidiary would constitute Qualifying Income to the fund. The IRS

20

Credit Suisse Managed Futures Strategy Fund
Notes to Consolidated Financial Statements (continued)
April 30, 2019 (unaudited)

Note 2. Significant Accounting Policies (continued)

has indicated that the granting of these types of private letter rulings is currently suspended.

If the Fund is unable to ensure continued qualification as a RIC, the Fund may be required to change its investment objective, policies or techniques, or may be liquidated. If the Fund fails to qualify as a RIC, the Fund will be subject to federal income tax on its net income and capital gains at regular corporate rates (without reduction for distributions to shareholders). If the Fund were to fail to qualify as a RIC and become subject to federal income tax, shareholders of the Fund would be subject to the risk of diminished returns.

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.

F) 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.

G) FUTURES — The Fund may enter into futures contracts to the extent permitted by its investment policies and objectives. The Fund may use futures contracts to gain exposure to or hedge against changes in interest rates, equity and market price movements and/or currency risks. Upon entering into a futures contract, the Fund is required to deposit cash and/or pledge U.S. Government securities as initial margin with a Futures Commission Merchant ("FCM"). Subsequent payments, which are dependent on the daily fluctuations in the value of the underlying instrument, are made or received by the Fund each day (daily variation margin) and are recorded as unrealized gains or losses in the Consolidated Statement of Operations until the contracts are closed. When the contracts are closed, the Fund records a realized gain or loss equal to the difference between the proceeds from (or cost of) the closing transaction and the Fund's basis in the contract. Risks of entering into futures contracts for hedging purposes include the possibility that a change in the value of the contract may not correlate with the changes in the value of the underlying

21

Credit Suisse Managed Futures Strategy Fund
Notes to Consolidated Financial Statements (continued)
April 30, 2019 (unaudited)

Note 2. Significant Accounting Policies (continued)

instruments. Futures have minimal counterparty credit risk because futures are exchange traded and the exchange's clearinghouse, as counterparty to all exchange-traded futures, guarantees the futures against default. In addition, the purchase of a futures contract involves the risk that the Fund could lose more than the original margin deposit and subsequent payments may be required for a futures transaction. The Fund's open futures contracts are disclosed in the Consolidated Schedule of Investments. At April 30, 2019, the amount of restricted cash held at brokers related to open futures contracts was $18,933,660.

The Commodity Exchange Act requires an FCM to segregate all customer transactions and assets from the FCM's proprietary activities. A customer's cash and other equity deposited with an FCM are considered commingled with all other customer funds subject to the FCM's segregation requirements. In the event of an FCM's insolvency, recovery may be limited to the Fund's pro-rata share of segregated customer funds available. It is possible that the recovery amount could be less than the total of cash and other equity deposited.

H) SWAPS — The Fund may enter into swap contracts either for hedging purposes or to seek to increase total return. A swap contract is an agreement that obligates two parties to exchange a series of cash flows at specified intervals based upon or calculated by reference to changes in specified prices or rates for a specified amount of an underlying asset or notional principal amount. The Fund will enter into swap contracts only on a net basis, which means that the two payment streams are netted out, with the Fund receiving or paying, as the case may be, only the net amount of the two payments. Risks may arise as a result of the failure of the counterparty to the swap contract to comply with the terms of the swap contract. The extent of the Fund's exposure to credit and counterparty risks is the discounted net value of the cash flows to be received from the counterparty over the contract's remaining life, to the extent that the amount is positive. These risks are mitigated by having a master netting arrangement between the Fund and the counterparty and by the posting of collateral by the counterparty to the Fund to cover the Fund's exposure to the counterparty. Therefore, the Fund considers the creditworthiness of each counterparty as well as the amounts posted by the counterparty pursuant to the master netting agreement to a swap contract in evaluating potential credit risk. Additionally, risks may arise from unanticipated movements in interest rates or in the value of the underlying reference asset or index.

22

Credit Suisse Managed Futures Strategy Fund
Notes to Consolidated Financial Statements (continued)
April 30, 2019 (unaudited)

Note 2. Significant Accounting Policies (continued)

The Fund may enter into total return swap contracts, involving commitments to pay interest in exchange for a market-linked return, both based on notional amounts. The Fund may invest in total return swap contracts for hedging purposes or to seek to increase total return. To the extent the total return of the security or index underlying the transaction exceeds or falls short of the offsetting interest rate obligation, the Fund will receive a payment from or make a payment to the counterparty.

The Fund records unrealized gains or losses on a daily basis representing the value and the current net receivable or payable relating to open swap contracts. Net amounts received or paid on the swap contract are recorded as realized gains or losses. Fluctuations in the value of swap contracts are recorded for financial statement purposes as unrealized appreciation or depreciation from swap contracts. Realized gains and losses from terminated swaps are included in net realized gains/losses from swap contracts. The Fund's open swap contracts are disclosed in the Consolidated Schedule of Investments. At April 30, 2019, the amount of restricted cash held at brokers related to open swap contracts was $2,050,000.

I) SECURITIES LENDING — The initial collateral received by the Fund is required to have a value of at least 102% of the market value of domestic securities on loan (including any accrued interest thereon) and 105% of the market value of foreign securities on loan (including any accrued interest thereon). The collateral is maintained thereafter at a value equal to at least 102% of the current market value of the securities on loan. The market value of loaned securities is determined at the close of each business day of the Fund and any additional required collateral is delivered to the Fund, or excess collateral returned by the Fund, on the next business day. Cash collateral received by the Fund in connection with securities lending activity may be pooled together with cash collateral for other funds/portfolios advised by Credit Suisse and may be invested in a variety of investments, including funds advised by SSB, the Fund's securities lending agent, or money market instruments. However, in the event of default or bankruptcy by the other party to the agreement, realization and/or retention of the collateral may be subject to legal proceedings.

SSB has been engaged by the Fund to act as the Fund's securities lending agent. 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. At April 30, 2019 and during the six months ended April 30, 2019, there were no securities out on loan.

23

Credit Suisse Managed Futures Strategy Fund
Notes to Consolidated Financial Statements (continued)

Note 2. Significant Accounting Policies (continued)

J) OTHER — 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 consolidated 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 Consolidated Statement of Assets and Liabilities.

K) RECENT ACCOUNTING PRONOUNCEMENTS — In March 2017, the FASB issued Accounting Standards Update 2017-08, Receivables — Nonrefundable Fees and Other Costs (Subtopic 310-20): Premium Amortization On Purchased Callable Debt Securities ("ASU 2017-08"). The update shortens the amortization period for the premium on certain purchased callable debt securities to the earliest call date. ASU 2017-08 will be effective for annual periods beginning after December 15, 2018. Management is currently assessing the potential impact of these changes to future financial statements.

Also, 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 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.

L) SUBSEQUENT EVENTS — In preparing the financial statements as of April 30, 2019, management considered the impact of subsequent events for potential recognition or disclosure in these financial statements through the date of release of this report. No such events requiring recognition or disclosure were identified through the date of the release of this report.

Note 3. Transactions with Affiliates and Related Parties

Credit Suisse serves as investment adviser and co-administrator for the Fund. For its investment advisory and administration services, Credit Suisse is entitled to receive a fee from the Fund at an annualized rate of 1.04% of the Fund's average daily net assets. For the six months ended April 30, 2019, investment advisory and administration fees earned and fees waived/expenses reimbursed by Credit Suisse were $1,424,026 and $50,569, respectively. Credit Suisse has contractually agreed to limit expenses so that the Fund's annual operating expenses do not exceed 1.30% of the Fund's average daily net assets for Class I shares, 1.55% of the Fund's average daily net assets for Class A shares, and 2.30% of the Fund's average daily net assets for Class C shares. The Fund is authorized to reimburse Credit Suisse for management fees previously limited and/or for expenses previously reimbursed by Credit Suisse, provided, however, that any reimbursements must be paid at a date not more than thirty-six months following the applicable month during which such fees were limited or expenses were reimbursed by Credit Suisse and the reimbursements do not cause the Fund to exceed the applicable expense limitation in the contract at the time the fees are recouped. This contract may not be terminated before February 28, 2020.

The amounts waived and reimbursed by Credit Suisse, which are available for potential future recoupment by Credit Suisse, and the expiration schedule at April 30, 2019 are as follows:

	Fee waivers/expense reimbursements subject to recoupment*		Expires October 31, 2019		Expires October 31, 2020		Expires October 31, 2021		Expires October 31, 2022
Class I	$	139,829	$	479	$	76,199	$	37,859	$	25,292
Class A		49,942		178		32,707		12,286		4,771
Class C		2,392		28		1,765		511		88
Totals	$	192,163	$	685	$	110,671	$	50,656	$	30,151

*  The Subsidiary expenses are not eligible for recoupment.

For its co-administrative services, SSB receives a fee, exclusive of out-of-pocket expenses, calculated in total for all the Credit Suisse funds/portfolios co-administered by SSB and allocated based upon the relative average net assets of each fund/portfolio, subject to an annual minimum fee. For the six months ended April 30, 2019, co-administrative services fees earned by SSB (including out-of-pocket expenses) with respect to the Fund were $20,579.

Credit Suisse Securities (USA) LLC ("CSSU"), an affiliate of Credit Suisse, serves as the distributor of the Fund's shares. Pursuant to a distribution plan adopted by the Fund pursuant to Rule 12b-1 under the 1940 Act, CSSU receives

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

fees for its distribution services. These fees are calculated at an annual rate of 0.25% of the average daily net assets of the Class A shares. For the Class C shares, the fee is calculated at an annual rate of 1.00% of the average daily net assets. For the six months ended April 30, 2019, the Fund paid Rule 12b-1 distribution fees of $52,183 for Class A shares and $4,022 for Class C shares.

Note 7. Contingencies

In the normal course of business, the Fund may provide general indemnifications pursuant to certain contracts and organizational documents.

Credit Suisse Managed Futures Strategy Fund
Board Approval of Investment Management Agreement (unaudited)

In approving the amended and restated investment management agreement (the "Investment Management Agreement") for the Credit Suisse Managed Futures Strategy Fund (the "Fund"), a series of Credit Suisse Opportunity Funds (the "Trust"), the Board of Trustees of the Trust (the "Board"), including all of the trustees who are not "interested persons" of the Trust as defined in the Investment Company Act of 1940 (the "Independent Trustees"), at a Special Telephonic Meeting held on November 7, 2018 where the Board discussed information and materials previously provided to them in connection with the renewal of the Investment Management Agreement, and at an in-person meeting held on November 12 and 13, 2018, considered the following factors:

Investment Management Fee Rates and Expenses

The Board reviewed and considered the contractual management fee rate of 1.04% of the Fund's average daily net assets ("Contractual Management Fee") for the Fund in light of the extent and quality of the management services provided by Credit Suisse Asset Management, LLC ("Credit Suisse"), the Fund's investment manager. The Board also considered that Credit Suisse has entered into a contractual expense limitation agreement ("Expense Limitation Agreement") limiting the Fund's total net expenses to 1.55%, 2.30% and 1.30% of the average daily net assets of Class A, Class C and Class I, respectively, until February 28, 2020.

Additionally, the Board received and considered information comparing the Fund's Contractual Management Fee, Contractual Management Fee less waivers and/or reimbursements ("Net Management Fee") and the Fund's overall expenses with those of funds in both the relevant expense group ("Expense Group") and universe of funds ("Expense Universe") provided by Broadridge, an independent provider of investment company data. The Board noted that the Fund's Contractual Management Fee, Net Management Fee and overall expenses were within the range of its peers as presented in the Broadridge report. The Board was provided with a description of the methodology used to arrive at the funds included in the Expense Group and the Expense Universe.

Nature, Extent and Quality of the Services under the Management Agreement

The Board received and considered information regarding the nature, extent and quality of services provided to the Fund by Credit Suisse under the Investment Management Agreement. The Board also noted information received at regular meetings throughout the year related to the services

29

Credit Suisse Managed Futures Strategy Fund
Board Approval of Investment Management Agreement (unaudited) (continued)

rendered by Credit Suisse which, in addition to portfolio management and investment management services set forth in the Investment Management Agreement, also included credit analysis and research, supervising the day to day operations of the Fund's non-advisory functions which include accounting, administration, custody, transfer agent and other applicable third party service providers, overseeing and facilitating audits, overseeing the Fund's credit facility and supervising and/or preparing applicable Fund filings, disclosures and shareholder reports. The Board noted that the extensive investment management services provided by Credit Suisse included broad supervisory responsibility and oversight over other service providers to the Fund. The Board also considered Credit Suisse's compliance program with respect to the Fund. The Board noted that Credit Suisse reports to the Board about portfolio management and compliance matters on a periodic basis. The Board reviewed background information about Credit Suisse including its Form ADV Part 2 — Disclosure Brochure and Brochure Supplement. The Board considered the background and experience of Credit Suisse's senior management and the expertise of, and the amount of attention given to the Fund by, senior personnel of Credit Suisse. In addition, the Board reviewed the qualifications, backgrounds and responsibilities of the portfolio management team primarily responsible for the day-to-day portfolio management of the Fund and the extent of the resources devoted to research and analysis of actual and potential investments, as well as the resources provided to them. The Board evaluated the ability of Credit Suisse, based on its resources, reputation and other attributes, to attract and retain qualified investment professionals including research, advisory, and supervisory personnel. The Board also received and considered information about the nature, extent and quality of services and fee rates offered to other Credit Suisse clients for comparable services. The Board acknowledged Credit Suisse's representation that the services provided to the Fund are more extensive than the services provided in connection with other types of accounts such as separate accounts offered by Credit Suisse and the services are also more extensive from those offered and provided to a sub-advised fund. The Board also considered that the services provided by Credit Suisse have expanded over time as a result of regulatory and other developments.

Fund Performance

The Board received and considered performance results of the Fund over the previous year as well as over longer time periods, along with comparisons both to the relevant performance group ("Performance Group") and universe of funds ("Performance Universe") for the Fund. The Board was provided with

30

Credit Suisse Managed Futures Strategy Fund
Board Approval of Investment Management Agreement (unaudited) (continued)

a description of the methodology used to arrive at the funds included in the Performance Group and the Performance Universe. The Board noted that the Fund underperformed its Performance Universe for the one-year period reported, and had varying performance compared to its Performance Universe over various longer investment periods reported. The Board also considered the investment performance of the Fund relative to its stated objectives.

Credit Suisse Profitability

The Board received and considered a profitability analysis of Credit Suisse based on the fees payable under the Investment Management Agreement for the Fund, including any fee waivers, as well as other relationships between the Fund on the one hand and Credit Suisse affiliates on the other. The Board deliberations also reflected Credit Suisse's methodology for allocating costs to the Fund, recognizing that cost allocation methodologies are inherently subjective. The Board also received net profitability information for the other funds in the Credit Suisse family of funds, which include both open-end and closed-end funds. The Board also reviewed Credit Suisse's profit margin as reflected in the profitability analysis, as well as reviewing profitability in light of appropriate court cases and the services rendered to the Fund.

Economies of Scale

The Board considered information regarding whether there have been economies of scale with respect to the management of the Fund, whether the Fund has appropriately benefited from any economies of scale, and whether there is potential for realization of any further economies of scale. The Board noted that as the Fund's asset levels continue to grow, economies of scale potentially could be realized and also noted the expense limitations currently in place between the Fund and Credit Suisse. The Board received information regarding Credit Suisse's historical profitability, including Credit Suisse's costs in providing services.

Other Benefits to Credit Suisse

The Board considered other benefits received by Credit Suisse and its affiliates as a result of their relationship with the Fund. Such benefits include, among others, benefits potentially derived from an increase in Credit Suisse's businesses as a result of its relationship with the Fund (such as the ability to market to shareholders other financial products offered by Credit Suisse and

31

Credit Suisse Managed Futures Strategy Fund
Board Approval of Investment Management Agreement (unaudited) (continued)

its affiliates) and the fees paid to an affiliate of Credit Suisse for distribution services.

The Board considered the standards applied in seeking best execution and their policies and practices regarding soft dollars and reviewed Credit Suisse's method for allocating portfolio investment opportunities among its advisory clients.

Other Factors and Broader Review

As discussed above, the Board reviewed detailed materials received from Credit Suisse as part of the annual approval process. The Board also reviews and assesses the quality of the services that the Fund receives throughout the year. In this regard, the Board reviews reports of Credit Suisse at least quarterly, which include, among other things, detailed portfolio and market reviews, detailed fund performance reports, and Credit Suisse's compliance procedures.

Conclusions

In selecting Credit Suisse, and approving the renewal of the Investment Management Agreement and the investment management fee under such agreement, the Board concluded that:

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

•  The Board was satisfied with the nature, extent and quality of the investment management services provided to the Fund by Credit Suisse and that, based on dialogue with management and counsel, the services provided by Credit Suisse under the Investment Management Agreement are typical of, and consistent with, those provided to similar mutual funds by other investment managers.

•  In light of the costs of providing investment management and other services to the Fund and Credit Suisse's ongoing commitment to the Fund and willingness to waive fees (by agreeing to an expense limitation), Credit Suisse's net profitability based on fees payable under the Investment Management Agreement, as well as other ancillary benefits that Credit Suisse and its affiliates received, were considered reasonable.

32

Credit Suisse Managed Futures Strategy Fund
Board Approval of Investment Management Agreement (unaudited) (continued)

•  In light of the information received and considered by the Board, the Fund's current fee structure was considered reasonable.

No single factor reviewed by the Board was identified by the Board as the principal factor in determining whether to approve the renewal of the Investment Management Agreement. The Independent Trustees were advised by separate independent legal counsel throughout the process.

Credit Suisse Multialternative Strategy Fund
Semiannual Investment Adviser's Report
April 30, 2019 (unaudited)

May 24, 2019

Dear Shareholder:

We are pleased to present this Semiannual Report covering the activities of the Credit Suisse Multialternative Strategy Fund (the "Fund") for the six-month period ended April 30, 2019.

Performance Summary
11/1/2018 – 04/30/2019

Fund & Benchmark	Performance
Class I1		2.75	%
Class A1,2		2.67	%
Credit Suisse Hedge Fund Index3		3.54	%
Credit Suisse Liquid Alternative Beta Index4		4.19	%

Performance shown for the Fund's Class A shares does not reflect sales charges, which are a maximum of 5.25%.²

Market Review: A positive, yet challenging period for multi-alternative strategies

The six-month period ended April 30, 2019 was overall a positive one for multi-alternative strategies, with the Credit Suisse Hedge Fund Index, the Fund's benchmark, gaining 3.54%. Following the market drawdown at the end of last year, markets regained confidence that formed into a broader recovery.

Equity markets made gains in the first quarter of 2019, rebounding from a weak end to 2018, as concerns over the China-US trade dispute eased and major central banks grew more accommodative. The central bank easing also helped Eurozone equities to recover. Worries over economic growth, however, lingered throughout the latter part of the period.

U.S. 10-year Treasury yields fell in the first quarter of 2019 to reach their lowest level since late 2017. Additionally, as a sign of growing caution around economic growth, the three-month Treasury bill yield rose higher than that of 10-year bonds in March.

Commodities had their best quarter in three years, with the Bloomberg Commodity Index making gains as concerns over Crude oil supplies kept demand relatively steady.

Strategic Review and Outlook: Positive results from a mixed period

For the six-month period ended April 30, 2019 the Fund's Class I shares returned 2.75%, while the Credit Suisse Hedge Fund Index returned 3.54% and

1

Credit Suisse Multialternative Strategy Fund
Semiannual Investment Adviser's Report (continued)
April 30, 2019 (unaudited)

the Credit Suisse Liquid Alternative Beta Index returned 4.19%. While maintaining a risk-balanced allocation, the portfolio benefited from a shift toward strategies that capitalized on the increased risk appetite in the market.

The sharp sell-off at the end of 2018 challenged value strategies. This was moderated by the harvesting of market trend/momentum strategies.

The seasonal commodity dynamics strategy — which is designed to harvest the seasonal relative performance differentials of fundamentally-linked pairs across the commodity complex — was the largest contributor to performance during Q1 2019.

A strategy designed to harvest the relative outperformance of companies that engage in equity buyback programs — also contributed positively during Q1 2019. The strategy was supported by robust equity buyback activity following the corporate tax cut.

Trend in short-term rates was another positive contributor during Q1 2019. The strategy had identified the gradual rate hiking cycle in the US, while the European Central Bank ("ECB") maintained rates in a 'lower for longer' approach.

Credit Developed Markets ("DM") carry exposures detracted from performance in Q4 2018. The convergence of equity turmoil, sliding oil prices, and fears over mounting corporate debt loads (since the Fed was signaling that it would raise rates faster than expectations) caused spreads to finish 2018 at the widest levels since 2016.

We continue to believe that the unique return profile of multi-alternative strategies may appeal to investors searching for meaningful performance drivers which draw on many hedge fund styles and which have historically offered diversification benefits to traditional portfolios.

The Fund is non-diversified, which means it may invest a greater proportion of its assets in the securities of a smaller number of issuers than a diversified mutual fund and may therefore be subject to greater volatility. The Fund's investment in alternative instruments may subject the Fund to greater volatility than investments in traditional securities, particularly in investments involving leverage.

The use of alternative assets and strategies entails substantial risks, including risk of loss of principal, arbitrage or fundamental risk, below investment grade securities risk, commodity exposure risks, concentration risk, credit risk, derivatives risk, exchange traded notes risk, fixed income risk, foreign securities risk, forwards risk, futures contracts risk, interest rate risk, leveraging risk, market risk, non-diversified status, portfolio turnover risk, risks of investing in other funds, small- and mid- cap stock risk, speculative exposure risk, subsidiary risk, swap agreements risk and tax risk. For a detailed discussion of these and other risks, please refer to the Fund's Prospectus, which should be read carefully before investing.

In addition to historical information, this report contains forward-looking statements, which may concern, among other things, domestic and foreign markets, industry and economic trends and developments and government regulation, and their potential impact on the Fund's investments. These statements are subject to risks and uncertainties and actual trends, developments and regulations in the future, and their impact on the Fund, could be materially different from those projected, anticipated or implied. The Fund has no obligation to update or revise forward-looking statements.

The views of the Fund's management are as of the date of this letter and the Fund holdings described in this document are as of April 30, 2019; 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  Fee waivers and/or expense reimbursements reduce expenses for the Fund, without which performance would be lower. The Fund has entered into a written contract limiting operating expenses to 0.85% of the Fund's average daily net assets for Class I shares and 1.10% of the Fund's average daily net assets for Class A shares at least through February 28, 2020. This limit excludes certain expenses, as set forth in the Fund's Prospectus.

²  Total return for the Fund's Class A shares for the reporting period, based on offering price (including maximum sales charge of (5.25%), was (2.72)%.

³  Credit Suisse Hedge Fund Index is compiled by Credit Suisse Hedge Index LLC. It is an asset-weighted hedge fund index and includes only hedge funds. It is rebalanced quarterly, is shown net of all performance fees and provides a rules-based and investable index, enabling investors to utilize the performance of a diversified market barometer for the hedge fund industry.

⁴  The Credit Suisse Liquid Alternative Beta Index reflects the return of a dynamic basket of liquid, investable market factors selected and weighted in accordance with an algorithm that aims to approximate the aggregate returns of the universe of hedge fund managers as represented by the Credit Suisse Hedge Fund Index.

Information About Your Fund's Expenses

As an investor of the Fund, you incur two types of costs: ongoing expenses and transaction costs. Ongoing expenses include management fees, distribution and service (12b-1) fees and other Fund expenses. Examples of transaction costs include sales charges (loads), redemption fees and account maintenance fees, which are not shown in this section and which would result in higher total expenses. The following table is intended to help you understand your ongoing expenses of investing in the Fund and to help you compare these expenses with the ongoing expenses of investing in other mutual funds. The table is based on an investment of $1,000 made at the beginning of the six months ended April 30, 2019.

The table illustrates your Fund's expenses in two ways:

•  Actual Fund Return. This helps you estimate the actual dollar amount of ongoing expenses paid on a $1,000 investment in the Fund using the Fund's actual return during the period. To estimate the expenses you paid over the period, simply divide your account value by $1,000 (for example, an $8,600 account value divided by $1,000 = 8.6), then multiply the result by the number in the "Expenses Paid per $1,000" line.

•  Hypothetical 5% Fund Return. This helps you to compare the Fund's ongoing expenses with those of other mutual funds using the Fund's actual expense ratio and a hypothetical rate of return of 5% per year before expenses. Examples using a 5% hypothetical fund return may be found in the shareholder reports of other mutual funds. The hypothetical account values and expenses may not be used to estimate the actual ending account balance or expenses you paid for the period.

Please note that the expenses shown in these tables are meant to highlight your ongoing expenses only and do not reflect any transaction costs, such as sales charges (loads) or redemption fees. If these transaction costs had been included, your costs would have been higher. The "Expenses Paid per $1,000" line of the tables is useful in comparing ongoing expenses only and will not help you determine the relative total expenses of owning different funds.

  The "Expenses Paid per $1,000" and the "Annualized Expense Ratios" in the tables are based on actual expenses paid by the Fund during the period, net of fee waivers and/or actual expense reimbursements, if applicable. If those fee waivers and/or expense reimbursements had not been in effect, the Fund's actual expenses would have been higher. Expenses do not reflect additional charges and expenses that are, or may be, imposed under the variable contracts or plans. Such charges and expenses are described in the prospectus of the insurance company separate account or in the plan documents or other informational materials supplied by plan sponsors. The Fund's expenses should be considered with these charges and expenses in evaluating the overall cost of investing in the separate account.

Note 1. Organization

Credit Suisse Multialternative Strategy Fund (the "Fund"), a series of Credit Suisse Opportunity Funds (the "Trust"), a Delaware statutory trust, is registered under the Investment Company Act of 1940, as amended (the "1940 Act"), as a non-diversified open-end management investment company that seeks to achieve total return consistent with the risk and return patterns of a diversified universe of hedge funds. The Trust was organized under the laws of the State of Delaware as a business trust on May 31, 1995.

Credit Suisse Asset Management, LLC ("Credit Suisse"), the investment adviser to the Fund, is registered as an investment adviser with the Securities and Exchange Commission and as a Commodity Pool Operator with the Commodity Futures Trading Commission. The Fund intends to gain exposure to commodity derivatives through investing in a wholly-owned subsidiary, Credit Suisse Cayman Multialternative Strategy Fund, Ltd. (the "Subsidiary"), organized under the laws of the Cayman Islands. The Subsidiary invests in commodity-linked derivative instruments, such as swaps and futures. The Subsidiary may also invest in debt securities, some of which are intended to serve as margin or collateral for the Subsidiary's derivatives positions.

The Subsidiary is managed by the same portfolio managers that manage the Fund and the accompanying financial statements reflect the financial position of the Fund and the Subsidiary and the results of operations on a consolidated basis. The consolidated financial statements include portfolio holdings of the Fund and the Subsidiary and all intercompany transactions and balances have been eliminated. The Fund may invest up to 25% of its total assets in the Subsidiary. As of April 30, 2019, the Fund held $8,013,662 in the Subsidiary, representing 10.1% of the Fund's consolidated net assets. For the six months ended April 30, 2019, the net realized gain on securities and other financial instruments held in the Subsidiary was $2,592,139.

Subsequent references to the Fund within the Notes to Consolidated Financial Statements collectively refer to the Fund and the Subsidiary.

The Fund offers two classes of shares: Class I shares and Class A shares. Each class of shares represents an equal pro rata interest in the Fund, except the share classes bear different expenses. Class A shares are sold subject to a front-end sales charge of up to 5.25%. Class I shares are sold without a sales charge.

Note 2. Significant Accounting Policies

The following is a summary of significant accounting policies followed by the Fund in the preparation of its consolidated financial statements. The policies are in accordance with generally accepted accounting principles in the United States of America ("GAAP"). The preparation of consolidated financial statements requires management to make estimates and assumptions that affect the reported amounts and disclosures in the consolidated 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 Boards's ("FASB") Accounting Standards Codification ("ASC") Topic 946 — Financial Services — Investment Companies.

A) SECURITY VALUATION — The Board of Trustees (the "Board") is responsible for the Fund's 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. For certain international equity securities, in order to adjust for events which may occur between the close of the foreign exchanges and the close of the Exchange, a fair valuation model may be used. This fair valuation model takes into account comparisons to the valuation of American Depository Receipts (ADRs), exchange-traded funds, futures contracts and certain indices and these securities are categorized as Level 2. 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

27

Credit Suisse Multialternative Strategy Fund
Notes to Consolidated Financial Statements (continued)

Note 2. Significant Accounting Policies (continued)

the underlying index. Option contracts on securities, currencies, indices, futures contracts, swaps and other instruments are valued at the mid-point between the last bid and ask quotations as of the close of trading on the exchange on which the option is traded. 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 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

28

Credit Suisse Multialternative Strategy Fund
Notes to Consolidated Financial Statements (continued)
April 30, 2019 (unaudited)

Note 2. Significant Accounting Policies (continued)

•  Level 2  –  other significant observable inputs (including quoted prices for similar investments, interest rates, prepayment speeds, credit risk, etc.)

•  Level 3  –  significant unobservable inputs (including the Fund's own assumptions in determining the fair value of investments)

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

The following is a summary of the inputs used as of April 30, 2019 in valuing the Fund's assets and liabilities carried at fair value:

Assets	Level 1		Level 2		Level 3		Total

*  Other financial instruments include unrealized appreciation (depreciation) on forward foreign currency contracts, futures and swap contracts. Written options are reported at value.

**  Value includes any premium paid or received with respect to swap contracts, if applicable.

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. For the six months ended April 30, 2019, the Fund's derivatives did not qualify for hedge accounting as they are held at fair value.

For the six months ended April 30, 2019, the Fund received average monthly premiums of $308,687 from written options contracts.

The Fund is a party to International Swap and Derivatives Association, Inc. ("ISDA") Master Agreements ("Master Agreements") with certain counterparties that govern over-the-counter derivative (including Total Return, Credit Default and Interest Rate Swaps) and foreign exchange contracts entered into by the Fund. The Master Agreements may contain provisions regarding, among other things, the parties' general obligations, representations, agreements, collateral requirements, events of default and early termination. Termination events applicable to the Fund may occur upon a decline in the Fund's net assets below a specified threshold over a certain period of time.

^(a)  Swap contracts, written options and forward foreign currency exchange contracts are included. Written options are reported at market value.

^(b)  The actual collateral pledged may be more than the amounts shown.

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

31

Credit Suisse Multialternative Strategy Fund
Notes to Consolidated Financial Statements (continued)

Note 2. Significant Accounting Policies (continued)

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 Consolidated 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. Foreign dividend income is recorded on the ex-dividend date or as soon as practicable after the Fund determines the existence of a dividend declaration after exercising reasonable due diligence. Certain expenses are class-specific expenses, vary by class and are charged only to that class. Income, expenses (excluding class-specific expenses) and realized/unrealized gains/losses are allocated proportionately to each class of shares based upon the relative net asset value of the outstanding shares of that class. 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 — Dividends from net investment income, if any, are declared and paid quarterly. 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.

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

32

Credit Suisse Multialternative Strategy Fund
Notes to Consolidated Financial Statements (continued)
April 30, 2019 (unaudited)

Note 2. Significant Accounting Policies (continued)

"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 Internal Revenue Service ("IRS") has issued a ruling that income realized from certain types of commodity-linked derivatives would not be Qualifying Income. As a result, the Fund's ability to realize income from investments in such commodity-linked derivatives as part of its investment strategy would be limited to a maximum of 10% of its gross income. The IRS has issued private letter rulings to registered investment companies concluding that income derived from their investment in a wholly-owned subsidiary would constitute Qualifying Income to the fund. The IRS has indicated that the granting of these types of private letter rulings is currently suspended.

If the Fund is unable to ensure continued qualification as a RIC, the Fund may be required to change its investment objective, policies or techniques, or may be liquidated. If the Fund fails to qualify as a RIC, the Fund will be subject to federal income tax on its net income and capital gains at regular corporate rates (without reduction for distributions to shareholders). If the Fund were to fail to qualify as a RIC and become subject to federal income tax, shareholders of the Fund would be subject to the risk of diminished returns. 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) SHORT SALES — When the Fund engages in a short sale, the collateral for the short position will be maintained by the Fund's custodian or qualified sub-custodian. While the short sale is open, the Fund will maintain in a segregated account an amount of liquid securities equal in value to its obligation to the securities sold short. The collateral amounts required are determined daily by reference to the market value of the short positions. Short sales expose the Fund to the risk that it will be required to cover its short position at a time when the securities have appreciated in value, thus resulting in a loss to the Fund. The Fund's loss on a short sale could theoretically be unlimited in a case where the Fund is unable, for whatever reason, to close out its short position. Short sales also involve transaction and other costs that will reduce potential gains and increase potential Fund losses. The use by the Fund of short sales in combination with long positions in the Fund in an attempt to improve performance may not be successful and may result in greater losses or lower positive returns than if the Fund held only long positions. It is possible that the Fund's long equity positions will decline in value at the same time that the value of the securities it has sold short increases, thereby increasing potential losses to the Fund. In addition, the Fund's short selling strategies may limit its ability to fully benefit from increases in the equity markets. Short selling also involves a form of financial leverage that may exaggerate any losses realized by the Fund. Also, there is the risk that the counterparty to a short sale may fail to honor its contractual terms, causing a loss to the Fund. At April 30, 2019, the amount of restricted cash held at brokers related to open short positions was $0.

I) FUTURES — The Fund may enter into futures contracts to the extent permitted by its investment policies and objectives. The Fund may use futures contracts to gain exposure to or hedge against changes in interest rates, equity and market price movements and/or currency risks. Upon entering into a futures contract, the Fund is required to deposit cash and/or pledge U.S. Government securities as initial margin with a Futures Commission Merchant ("FCM"). Subsequent payments, which are dependent on the daily fluctuations in the value of the underlying instrument, are made or received by the Fund each day (daily variation margin) and are recorded as unrealized gains or losses in the Consolidated Statement of Operations until the contracts are closed. When the contracts are closed, the Fund records a realized gain or loss equal

34

Credit Suisse Multialternative Strategy Fund
Notes to Consolidated Financial Statements (continued)
April 30, 2019 (unaudited)

Note 2. Significant Accounting Policies (continued)

to the difference between the proceeds from (or cost of) the closing transaction and the Fund's basis in the contract. Risks of entering into futures contracts for hedging purposes include the possibility that a change in the value of the contract may not correlate with the changes in the value of the underlying instruments. Futures have minimal counterparty credit risk because futures are exchange traded and the exchange's clearinghouse, as counterparty to all exchange-traded futures, guarantees the futures against default. In addition, the purchase of a futures contract involves the risk that the Fund could lose more than the original margin deposit and subsequent payments may be required for a futures transaction. The Fund's open futures contracts are disclosed in the Consolidated Schedule of Investments. At April 30, 2019, the amount of restricted cash held at brokers related to open futures contracts was $6,185,883.

The Commodity Exchange Act requires an FCM to segregate all customer transactions and assets from the FCM's proprietary activities. A customer's cash and other equity deposited with an FCM are considered commingled with all other customer funds subject to the FCM's segregation requirements. In the event of an FCM's insolvency, recovery may be limited to the Fund's pro-rata share of segregated customer funds available. It is possible that the recovery amount could be less than the total of cash and other equity deposited.

J) FORWARD FOREIGN CURRENCY CONTRACTS — A forward foreign currency exchange contract ("forward currency contract") is a commitment to purchase or sell a foreign currency at the settlement date at a negotiated rate. The Fund will enter into forward currency contracts primarily for hedging foreign currency risk. Forward currency contracts are valued at the prevailing forward exchange rate of the underlying currencies and unrealized gain/loss is recorded daily. On the settlement date of the forward currency contract, the Fund records a realized gain or loss equal to the difference between the value of the contract at the time it was opened and the value of the contract at the time it was closed. Certain risks may arise upon entering into forward currency contracts from the potential inability of counterparties to meet the terms of their contracts. The maximum counterparty credit risk to the Fund is measured by the unrealized gain on appreciated contracts. Additionally, when utilizing forward currency contracts to hedge, the Fund forgoes the opportunity to profit from favorable exchange rate movements during the term of the contract. The Fund's open forward currency contracts at April 30, 2019 are disclosed in the Consolidated Schedule of Investments.

Note 2. Significant Accounting Policies (continued)

K) SWAPS — The Fund may enter into swaps either for hedging purposes or to seek to increase total return. A swap contract is an agreement that obligates two parties to exchange a series of cash flows at specified intervals based upon or calculated by reference to changes in specified prices or rates for a specified amount of an underlying asset or notional principal amount. A centrally cleared swap is a transaction executed between the Fund and a counterparty, then cleared by a clearing member through a central clearinghouse. The central clearinghouse serves as the counterparty, with whom the Fund exchanges cash flows. The Fund will enter into swap contracts only on a net basis, which means that the two payment streams are netted out, with the Fund receiving or paying, as the case may be, only the net amount of the two payments. Risks may arise as a result of the failure of the counterparty to the swap contract to comply with the terms of the swap contract. The extent of the Fund's exposure to credit and counterparty risks is the discounted net value of the cash flows to be received from the counterparty over the contract's remaining life, to the extent that the amount is positive. These risks are mitigated by having a master netting arrangement between the Fund and the counterparty and by the posting of collateral by the counterparty to the Fund to cover the Fund's exposure to the counterparty. Therefore, the Fund considers the creditworthiness of each counterparty as well as the amounts posted by the counterparty pursuant to the master netting agreement to a swap contract in evaluating potential credit risk. Additionally, risks may arise from unanticipated movements in interest rates or in the value of the underlying reference asset or index.

The Fund may enter into total return swap contracts, involving commitments to pay interest in exchange for a market-linked return, both based on notional amounts. The Fund may invest in total return swap contracts for hedging purposes or to seek to increase total return. To the extent the total return of the security or index underlying the transaction exceeds or falls short of the offsetting interest rate obligation, the Fund will receive a payment from or make a payment to the counterparty.

The Fund may enter into credit default swap agreements either as a buyer or seller. The Fund may buy a credit default swap to attempt to mitigate the risk of default or credit quality deterioration in one or more individual holdings or in a segment of the fixed income securities market. The Fund may sell a credit default swap in an attempt to gain exposure to an underlying issuer's credit quality characteristics without investing directly in that issuer.

36

Credit Suisse Multialternative Strategy Fund

April 30, 2019 (unaudited)

Note 2. Significant Accounting Policies (continued)

The Fund bears the risk of loss of the amount expected to be received under a credit default swap agreement in the event of the default or bankruptcy of the counterparty. The Fund will enter into swap agreements only with counterparties that meet certain standards of creditworthiness (generally, such counterparties would have to be eligible counterparties under the terms of the Fund's repurchase agreement guidelines). Credit default swap agreements are generally valued at a price at which the counterparty to such agreement would terminate the agreement.

The Fund records unrealized gains or losses on a daily basis representing the value and the current net receivable or payable relating to open swap contracts. Net amounts received or paid on the swap contract are recorded as realized gains or losses. Fluctuations in the value of swap contracts are recorded for financial statement purposes as unrealized appreciation or depreciation from swap contracts. Realized gains and losses from terminated swaps are included in net realized gains/losses from swap contracts. Upon entering into a centrally cleared swap, the Fund is required to deposit with a financial intermediary cash or securities ("initial margin") in an amount equal to a certain percentage of the notional amount of the swap. Subsequent payments ("variation margin") are made or received by the Fund dependent upon the daily fluctuations in the value of the swap. In a cleared swap transaction, counterparty risk is minimized as the central clearinghouse acts as the counterparty. The Fund's open swap contracts are disclosed in the Consolidated Schedule of Investments. At April 30, 2019, the amounts of restricted cash held at brokers related to open swap contracts for the Fund was $24,181,279.

L) OPTION CONTRACTS — The Fund will enter into options contracts to gain exposure to risk volatility based assets. When the Fund purchases an option, it pays a premium and the option is subsequently marked to market to reflect current value. Premiums paid for purchasing options which expire are treated as realized losses. Premiums paid for purchasing options which are exercised or closed are added to the cost or deducted from the proceeds on the underlying instrument to determine the realized gain or loss. The risk associated with purchasing options is limited to the premium paid.

When the Fund writes an option, an amount equal to the net premium received (the premium less commission) is recorded as a liability and is subsequently adjusted to the current value. Net premiums received for written options which expire are treated as realized gains. Net premiums received for written options which are exercised or closed are deducted from the cost or

37

Credit Suisse Multialternative Strategy Fund
Notes to Consolidated Financial Statements (continued)
April 30, 2019 (unaudited)

Note 2. Significant Accounting Policies (continued)

added to the proceeds on the underlying instrument or closing purchase transaction to determine the realized gain or loss. The Fund, as writer of a written option, bears the risk of an unfavorable change in the market value of the instrument underlying the written option.

Exchange-traded options have standardized contracts and are settled through a clearing house with fulfillment guaranteed by the credit of the exchange. Therefore, counterparty credit risks to the Fund are limited. Over-the-counter options are subject to the risk that the counterparty is unable or unwilling to meet its obligations under the option. The Fund's exchange-traded written options are disclosed in the Consolidated Schedule of Investments. At April 30, 2019, the amount of restricted cash held at brokers related to option contracts was $2,329,359.

M) SECURITIES LENDING — The initial collateral received by the Fund is required to have a value of at least 102% of the market value of domestic securities on loan (including any accrued interest thereon) and 105% of the market value of foreign securities on loan (including any accrued interest thereon). The collateral is maintained thereafter at a value equal to at least 102% of the current market value of the securities on loan. The market value of loaned securities is determined at the close of each business day of the Fund and any additional required collateral is delivered to the Fund, or excess collateral returned by the Fund, on the next business day. Cash collateral received by the Fund in connection with securities lending activity may be pooled together with cash collateral for other funds/portfolios advised by Credit Suisse and may be invested in a variety of investments, including funds advised by SSB, the Fund's securities lending agent, or money market instruments. However, in the event of default or bankruptcy by the other party to the agreement, realization and/or retention of the collateral may be subject to legal proceedings.

SSB has been engaged by the Fund to act as the Fund's securities lending agent. As of April 30, 2019, the Fund had investment securities on loan with a fair value of $1,325,002. Collateral received for securities loaned and a related liability of $1,366,325 are presented gross in the Consolidated Statement of Assets and Liabilities. The collateral for securities loaned is valued consistently with the other investments held by the Fund and is included in Level 2 of the fair value hierarchy. As of April 30, 2019, the value of the related collateral exceeded the value of the securities loaned.

38

Credit Suisse Multialternative Strategy Fund
Notes to Consolidated Financial Statements (continued)
April 30, 2019 (unaudited)

Note 2. Significant Accounting Policies (continued)

During the six months ended April 30, 2019, total earnings from the Fund's investment in cash collateral received in connection with securities lending arrangements was $15,354, of which $11,560 was rebated to borrowers (brokers). The Fund retained $2,844 in income from the cash collateral investment, and SSB, as lending agent, was paid $950. Securities lending income is accrued as earned.

N) OTHER — 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 consolidated 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 Consolidated Statement of Assets and Liabilities.

O) FOREIGN INVESTMENTS RISK — The Fund may have elements of risk not typically associated with investments in the U.S. due to concentrated investments in a limited number of countries or regions, which may vary throughout the year. Such concentrations may subject the Fund to additional risks resulting from political or economic conditions in such countries or regions and the possible imposition of adverse governmental laws or currency exchange restrictions could cause the securities and their markets to be less liquid and their prices to be more volatile than those of comparable U.S. securities.

Because the Fund may invest a significant portion of its assets in these markets, it is subject to greater risks of adverse events that occur in those markets and may experience greater volatility than a Fund that is more broadly diversified geographically.

P) RECENT ACCOUNTING PRONOUNCEMENTS — In March 2017, the FASB issued Accounting Standards Update 2017-08, Receivables — Nonrefundable Fees and Other Costs (Subtopic 310-20): Premium Amortization On Purchased Callable Debt Securities ("ASU 2017-08"). The update shortens the amortization period for the premium on certain purchased callable debt securities to the earliest

Note 2. Significant Accounting Policies (continued)

call date. ASU 2017-08 will be effective for annual periods beginning after December 15, 2018. Management is currently assessing the potential impact of these changes to future financial statements.

Also, 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 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.

Q) SUBSEQUENT EVENTS — In preparing the financial statements as of April 30, 2019, management considered the impact of subsequent events for potential recognition or disclosure in these financial statements through the date of release of this report. No such events requiring recognition or disclosure were identified through the date of the release of this report.

Note 3. Transactions with Affiliates and Related Parties

Credit Suisse serves as investment adviser and co-administrator for the Fund. Credit Suisse is entitled to receive a fee from the Fund at an annual rate of 1.04% of the Fund's average daily net assets. For the year ended six months ended April 30, 2019, investment advisory and administration fees earned and fees waived/expenses reimbursed by Credit Suisse were $418,022 and $478,259, respectively. Credit Suisse has contractually agreed to limit expenses so that the Fund's annual operating expenses do not exceed 0.85% of the Fund's average daily net assets for Class I shares and 1.10% of the Fund's average daily net assets for Class A shares. The Fund is authorized to reimburse Credit Suisse for management fees previously limited and/or for expenses previously reimbursed by Credit Suisse, provided, however, that any reimbursements must be paid at a date not more than thirty-six months following the applicable month during which such fees were limited or expenses were reimbursed by Credit Suisse and the reimbursements do not cause the Fund to exceed the applicable expense limitation in the contract at the time the fees are recouped. This contract may not be terminated before February 28, 2020. The amounts waived and reimbursed by Credit Suisse, which are available for potential

For its co-administrative services, SSB receives a fee, exclusive of out-of-pocket expenses, calculated in total for all the Credit Suisse funds/portfolios co-administered by SSB and allocated based upon the relative average net assets of each fund/portfolio, subject to an annual minimum fee. For the six months ended April 30, 2019, co-administrative services fees earned by SSB (including out-of-pocket expenses) with respect to the Fund were $17,078.

Credit Suisse Securities (USA) LLC ("CSSU"), an affiliate of Credit Suisse, serves as the distributor of the Fund's shares. Pursuant to a distribution plan adopted by the Fund pursuant to Rule 12b-1 under the 1940 Act, CSSU receives fees for its distribution services. These fees are calculated at an annual rate of 0.25% of the average daily net assets of the Class A shares. For the six months ended April 30, 2019, the Fund paid Rule 12b-1 distribution fees of $1,552 for Class A shares. Class I shares are not subject to Rule 12b-1 distribution fees.

Certain brokers, dealers and financial representatives provide transfer agent-related services to the Fund and receive compensation from the Fund. For the six months ended April 30, 2019, the Fund paid $28,747, which is included within transfer agent fees in the Consolidated Statement of Operations.

For the six months ended April 30, 2019, CSSU and its affiliates advised the Fund that there were no commissions earned on the sale of Class A shares.

Note 4. Line of Credit

The Fund, together with other funds/portfolios advised by Credit Suisse (collectively, the "Participating Funds"), participates in a committed, unsecured line of credit facility ("Credit Facility"), with SSB in an aggregated amount of $250 million for temporary or emergency purposes under a first-come, first-served basis. Under the terms of the Credit Facility, the Participating Funds pay an aggregate commitment fee on the average unused amount of the Credit

Note 4. Line of Credit (continued)

Facility, which is allocated among the Participating Funds in such manner as is determined by the governing Boards of the Participating Funds. In addition, the Participating Funds pay interest on borrowings at either the Overnight Federal Funds rate or the Overnight LIBOR rate plus a spread. At April 30, 2019 and during the six months ended April 30, 2019, the Fund had no borrowings outstanding under the Credit Facility.

Note 5. Purchases and Sales of Securities

For the six months ended April 30, 2019, purchases and sales of investment securities (excluding short-term investments) were $30,924,965 and $77,732,654, respectively.

Note 6. Capital Share Transactions

The Fund is authorized to issue an unlimited number of full and fractional shares of beneficial interest, $.001 par value per share. The Fund offers Class I shares and Class A shares. Class C was redeemed on February 15, 2018 and currently has no shareholders. Transactions in capital shares for each class of the Fund were as follows:

	Class I

	Number of Shareholders		Approximate Percentage of Outstanding Shares
Class I		4		98	%
Class A		4		73	%

The Fund's performance may be negatively impacted in the event one or more of the Fund's greater than 5% shareholders were to redeem at a given time. Some of the shareholders may be omnibus accounts, which hold shares on behalf of individual shareholders.

Note 7. Contingencies

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

43

Credit Suisse Multialternative Strategy Fund
Board Approval of Investment Management Agreement (unaudited)

In approving the amended and restated investment management agreement (the "Investment Management Agreement") for the Credit Suisse Multialternative Strategy Fund (the "Fund"), a series of Credit Suisse Opportunity Funds (the "Trust"), the Board of Trustees of the Trust (the "Board"), including all of the trustees who are not "interested persons" of the Trust as defined in the Investment Company Act of 1940 (the "Independent Trustees"), at a Special Telephonic Meeting held on November 7, 2018 where the Board discussed information and materials previously provided to them in connection with the renewal of the Investment Management Agreement, and at an in-person meeting held on November 12 and 13, 2018, considered the following factors:

Investment Management Fee Rates and Expenses

The Board reviewed and considered the contractual management fee rate of 1.04% of the Fund's average daily net assets (the "Contractual Management Fee") for the Fund in light of the extent and quality of the management services provided by Credit Suisse Asset Management, LLC ("Credit Suisse"), the Fund's investment manager. The Board also considered that Credit Suisse entered into a contractual expense limitation agreement ("Expense Limitation Agreement") limiting the Fund's total net expenses to 1.10%, 1.85% and 0.85% of the average daily net assets of Class A, Class C and Class I, respectively, until February 28, 2020.

Additionally, the Board received and considered information comparing the Fund's Contractual Management Fee, Contractual Management Fee less waivers and/or reimbursements ("Net Management Fee") and the Fund's overall expenses with those of funds in both the relevant expense group ("Expense Group") and universe of funds ("Expense Universe") provided by Broadridge, an independent provider of investment company data. The Board noted that the Fund's Contractual Management Fee, Net Management Fee and overall expenses were within the range of its peers as presented in the Broadridge report. The Board was provided with a description of the methodology used to arrive at the funds included in the Expense Group and the Expense Universe.

Nature, Extent and Quality of the Services under the Management Agreement

The Board received and considered information regarding the nature, extent and quality of services provided to the Fund by Credit Suisse under the Investment Management Agreement. The Board also noted information

44

Credit Suisse Multialternative Strategy Fund
Board Approval of Investment Management Agreement (unaudited) (continued)

received at regular meetings throughout the year related to the services rendered by Credit Suisse which, in addition to portfolio management and investment management services set forth in the Investment Management Agreement, also included credit analysis and research, supervising the day to day operations of the Fund's non-advisory functions which include accounting, administration, custody, transfer agent and other applicable third party service providers, overseeing and facilitating audits, overseeing the Fund's credit facility and supervising and/or preparing applicable Fund filings, disclosures and shareholder reports. The Board noted that the extensive investment management services provided by Credit Suisse included broad supervisory responsibility and oversight over other service providers to the Fund. The Board also considered Credit Suisse's compliance program with respect to the Fund. The Board noted that Credit Suisse reports to the Board about portfolio management and compliance matters on a periodic basis. The Board reviewed background information about Credit Suisse including its Form ADV Part 2 — Disclosure Brochure and Brochure Supplement. The Board considered the background and experience of Credit Suisse's senior management and the expertise of, and the amount of attention given to the Fund by, senior personnel of Credit Suisse. In addition, the Board reviewed the qualifications, backgrounds and responsibilities of the portfolio management team primarily responsible for the day-to-day portfolio management of the Fund and the extent of the resources devoted to research and analysis of actual and potential investments, as well as the resources provided to them. The Board evaluated the ability of Credit Suisse, based on its resources, reputation and other attributes, to attract and retain qualified investment professionals including research, advisory, and supervisory personnel. The Board also received and considered information about the nature, extent and quality of services and fee rates offered to other Credit Suisse clients for comparable services. The Board acknowledged Credit Suisse's representation that the services provided to the Fund are more extensive than the services provided in connection with other types of accounts, such as separate accounts, offered by Credit Suisse and the services also are more extensive from those offered and provided to a sub-advised fund. The Board also considered that the services provided by Credit Suisse have expanded over time as a result of regulatory and other developments.

Fund Performance

The Board received and considered performance results of the Fund over the previous year as well as over longer time periods, along with comparisons both to the relevant performance group ("Performance Group") and universe

45

Credit Suisse Multialternative Strategy Fund
Board Approval of Investment Management Agreement (unaudited) (continued)

of funds ("Performance Universe") for the Fund. The Board was provided with a description of the methodology used to arrive at the funds included in the Performance Group and the Performance Universe. The Board noted that the Fund performed in line with its Performance Universe for the one-year period reported, and that the Fund performed either in line with or slightly outperformed its Performance Universe over various longer investment periods reported. The Board also considered the investment performance of the Fund relative to its stated objectives.

Credit Suisse Profitability

The Board received and considered a profitability analysis of Credit Suisse based on the fees payable under the Investment Management Agreement for the Fund, including any fee waivers, as well as other relationships between the Fund on the one hand and Credit Suisse affiliates on the other. The Board deliberations also reflected Credit Suisse's methodology for allocating costs to the Fund, recognizing that cost allocation methodologies are inherently subjective. The Board also received net profitability information for the other funds in the Credit Suisse family of funds, which include both open-end and closed-end funds. The Board also reviewed Credit Suisse's profit margin as reflected in the profitability analysis, as well as reviewing profitability in light of appropriate court cases and the services rendered to the Fund.

Economies of Scale

The Board considered information regarding whether there have been economies of scale with respect to the management of the Fund, whether the Fund has appropriately benefited from any economies of scale, and whether there is potential for realization of any further economies of scale. The Board noted that as the Fund continues to grow, economics of scale potentially could be realized and noted the expense limitations currently in place between the Fund and Credit Suisse. The Board received information regarding Credit Suisse's historical profitability, including Credit Suisse's costs in providing services.

Other Benefits to Credit Suisse

The Board considered other benefits received by Credit Suisse and its affiliates as a result of their relationship with the Fund. Such benefits include, among others, benefits potentially derived from an increase in Credit Suisse's businesses as a result of its relationship with the Fund (such as the ability to

46

Credit Suisse Multialternative Strategy Fund
Board Approval of Investment Management Agreement (unaudited) (continued)

market to shareholders other financial products offered by Credit Suisse and its affiliates) and the fees paid to an affiliate of Credit Suisse for distribution services.

The Board considered the standards applied in seeking best execution and their policies and practices regarding soft dollars and reviewed Credit Suisse's method for allocating portfolio investment opportunities among its advisory clients.

Other Factors and Broader Review

As discussed above, the Board reviewed detailed materials received from Credit Suisse as part of the annual approval process. The Board also reviews and assesses the quality of the services that the Fund receives throughout the year. In this regard, the Board reviews reports of Credit Suisse at least quarterly, which include, among other things, detailed portfolio and market reviews, detailed fund performance reports and Credit Suisse's compliance procedures.

Conclusions

In selecting Credit Suisse, and approving the renewal of the Investment Management Agreement and the investment management fee under such agreement, the Board concluded that:

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

•  The Board was satisfied with the nature, extent and quality of the investment management services provided to the Fund by Credit Suisse and that, based on dialogue with management and counsel, the services provided by Credit Suisse under the Investment Management Agreement are typical of, and consistent with, those provided to similar mutual funds by other investment managers.

•  In light of the costs of providing investment management and other services to the Fund and Credit Suisse's ongoing commitment to the Fund and willingness to waive fees (by agreeing to an expense limitation), Credit Suisse's net profitability based on fees payable under the Investment Management Agreement, as well as other ancillary benefits that Credit Suisse and its affiliates received, were considered reasonable.

Board Approval of Investment Management Agreement (unaudited) (continued)

•  In light of the information received and considered by the Board, the Fund's current fee structure was considered reasonable.

No single factor reviewed by the Board was identified by the Board as the principal factor in determining whether to approve the renewal of the Investment Management Agreement. The Independent Trustees were advised by separate independent legal counsel throughout the process.

Semiannual Investment Adviser's Report

May 23, 2019

Dear Shareholder:

We are pleased to present this Semiannual Report covering the activities of the Credit Suisse Strategic Income Fund (the "Fund") for the six-month period ended April 30, 2019.

Performance Summary
11/1/2018 – 04/30/19

Fund & Benchmark	Performance
Class I1		3.47	%
Class A1,2		3.45	%
Class C1,2		3.07	%
ICE BofAML 3-Month US Treasury Bill Index3		1.18	%

Performance shown for the Fund's Class A and Class C Shares does not reflect sales charges, which are a maximum of 4.75% and 1.00%, respectively.²

Market Review: A positive period overall

The six-month period ended April 30, 2019 was a positive one for both the high yield and senior secured loan asset classes, with the Credit Suisse Leveraged Loan Index returning 2.17% and the ICE BofAML US High Yield Constrained Index returning 5.48%. Additionally, the ICE BofAML 3-Month US Treasury Bill Index, the Fund's benchmark, returned 1.18% for the period.

Both global equity and high yield markets struggled toward the end of 2018 due to uncertainty around U.S. monetary policy and the accompanying risk-off sentiment. In the beginning of 2019, however, credit and high yield markets recovered, as long-end U.S. interest rates declined, leading to increased demand for the asset classes and positive momentum for markets in general. For loans, the dovish stance taken by the Federal Reserve in late 2018 led to outflows from mutual funds.

Default activity, as measured by JPMorgan, ended the period at 1.38% for high yield and 1.29% for the leveraged loan asset class — signaling stable fundamentals for the asset classes.

Strategic Review and Outlook: Expecting security and sector selection to drive performance

For the six-month period ended April 30, 2019, the Fund's A-, C-, and I-class shares outperformed the benchmark. The Fund's outperformance is largely

1

Credit Suisse Strategic Income Fund
Semiannual Investment Adviser's Report (continued)
April 30, 2019 (unaudited)

attributable to positive selection within the high yield asset and leveraged loan asset classes. Additionally, positions in Ba3 and B-rated issues, as well as those in buildings and real estate, and chemicals and conglomerates contributed most significantly to relative returns.

Though it has been a quiet period for primary loan issuance, leveraged loans have gotten off to a strong start in 2019. In addition, high yield inflows have been positive for asset class returns. We expect default rates for both the high yield and senior secured loan markets will remain below historical averages in the near to intermediate term. However, we note that markets have been sensitive to interest rate volatility given the pivot in Fed expectations. Consequently, we continue to take advantage of relative risk opportunities that arise from changes in sentiment. Given the activities of the past six months and the increased volatility experienced, we continue to expect security and sector selection will be a major driver of performance — especially if greater divergence amongst sector and credit returns is realized.

Senior secured floating rate loans ("Senior Loans") typically hold the most senior position in the issuer's capital structure. Senior Loans are subject to the risk that a court could subordinate a Senior Loan to presently existing or future indebtedness or take other action detrimental to the holders of Senior Loans.

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.

CLOs are subject to the risk of substantial losses due to actual defaults, decrease of market value due to collateral defaults and disappearance of subordinate tranches, market anticipation of defaults, and investor aversion to CLO securities as a class. The risks of CLOs depend largely on the type of the underlying loans and the tranche of CLOs in which the Fund invests. In addition, CLOs carry risks including interest rate risk and credit risk.

Additional principal risk factors for the Fund include conflict of interest risk, convertible securities risk, credit risk, derivatives risk, extension risk, foreign securities risk, futures contracts risk, hedged exposure risk, interest rate risk, liquidity risk, market risk, mortgage- and asset-backed securities risk, prepayment risk, short position risk, U.S. government securities risk and valuation risk. Before you invest, please make sure you understand the risks that apply to the Fund. As with any mutual fund, you could lose money over any period of time. Investments in the Fund are not bank deposits and are not insured or guaranteed by the Federal Deposit Insurance Corporation or any government agency. For a detailed discussion of these and other risks, please refer to the Fund's Prospectus, which should be read carefully before investing.

In addition to historical information, this report contains forward-looking statements, which may concern, among other things, domestic and foreign markets, industry and economic trends and developments and government regulation and their potential impact on the Fund's investments. These statements are subject to risks and uncertainties and actual trends, developments and regulations in the future, and their impact on the Fund could be materially different from those projected, anticipated or implied. The Fund has no obligation to update or revise forward-looking statements.

The views of the Fund's management are as of the date of this letter and the Fund holdings described in this document are as of April 30, 2019; 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  Fee waivers and/or expense reimbursements reduce expenses for the Fund, without which performance would be lower. Effective April 22, 2019, the Fund entered into a written contract to limit expenses to 0.99% of the Fund's average daily net assets for Class I shares, 1.24% of the Fund's average daily net assets for Class A shares and 1.99% of the Fund's average daily net assets for Class C shares through at least February 28, 2020. This limit excludes certain expenses, as set forth in the Fund's Prospectus.

²  Total return for the Fund's Class A shares for the reporting period, based on offering price (including maximum sales charge of 4.75%), was (1.49)%. Total return for the Fund's Class C shares for the reporting period, based on redemption value (including maximum contingent deferred sales charge ("CDSC") of 1.00%), was 2.07%.

³  The ICE BofAML 3-Month U.S. Treasury Bill Index is comprised of a single issue purchased at the beginning of the month and held for a full month. Each month the index is rebalanced and the issue selected is the outstanding Treasury Bill that matures closest to, but not beyond 3 months from the rebalancing date. The index does not have transaction costs and investors may not invest directly in the index.

Information About Your Fund's Expenses

As an investor of the Fund, you incur two types of costs: ongoing expenses and transaction costs. Ongoing expenses include management fees, distribution and service (12b-1) fees and other Fund expenses. Examples of transaction costs include sales charges (loads), redemption fees and account maintenance fees, which are not shown in this section and which would result in higher total expenses. The following table is intended to help you understand your ongoing expenses of investing in the Fund and to help you compare these expenses with the ongoing expenses of investing in other mutual funds. The table is based on an investment of $1,000 made at the beginning of the six months ended April 30, 2019.

The table illustrates your Fund's expenses in two ways:

•  Actual Fund Return. This helps you estimate the actual dollar amount of ongoing expenses paid on a $1,000 investment in the Fund using the Fund's actual return during the period. To estimate the expenses you paid over the period, simply divide your account value by $1,000 (for example, an $8,600 account value divided by $1,000 = 8.6), then multiply the result by the number in the "Expenses Paid per $1,000" line.

•  Hypothetical 5% Fund Return. This helps you to compare the Fund's ongoing expenses with those of other mutual funds using the Fund's actual expense ratio and a hypothetical rate of return of 5% per year before expenses. Examples using a 5% hypothetical fund return may be found in the shareholder reports of other mutual funds. The hypothetical account values and expenses may not be used to estimate the actual ending account balance or expenses you paid for the period.

Please note that the expenses shown in these tables are meant to highlight your ongoing expenses only and do not reflect any transaction costs, such as sales charges (loads) or redemption fees. If these transaction costs had been included, your costs would have been higher. The "Expenses Paid per $1,000" line of the tables is useful in comparing ongoing expenses only and will not help you determine the relative total expenses of owning different funds.

	Class I			Class A			Class C
Annualized Expense Ratios*		0.99	%		1.24	%		1.99	%

*  Expenses are equal to the Fund's annualized expense ratio for each share class, multiplied by the average account value over the period, multiplied by 181/365 to reflect the one-half year period.

  The "Expenses Paid per $1,000" and the "Annualized Expense Ratios" in the tables are based on actual expenses paid by the Fund during the period, net of fee waivers and/or actual expense reimbursements, if applicable. If those fee waivers and/or expense reimbursements had not been in effect, the Fund's actual expenses would have been higher. Expenses do not reflect additional charges and expenses that are, or may be, imposed under the variable contracts or plans. Such charges and expenses are described in the prospectus of the insurance company separate account or in the plan documents or other informational materials supplied by plan sponsors. The Fund's expenses should be considered with these charges and expenses in evaluating the overall cost of investing in the separate account.

For more information, please refer to the Fund's Prospectus.

Note 1. Organization

Credit Suisse Strategic Income Fund (the "Fund"), a series of Credit Suisse Opportunity Funds (the "Trust"), a Delaware statutory trust, is registered under the Investment Company Act of 1940, as amended (the "1940 Act"), as a non-diversified open-end management investment company that seeks total return. The Trust was organized under the laws of the State of Delaware as a business trust on May 31, 1995.

The Fund offers three classes of shares: Class I shares, Class A shares and Class C shares. Each class of shares represents an equal pro rata interest in the Fund, except the share classes bear different expenses. Class A shares are sold subject to a front-end sales charge of up to 4.75%. Class C shares are sold subject to a contingent deferred sales charge ("CDSC") of 1.00% if the shares are redeemed within the first year of purchase. Class I shares are sold without a sales charge.

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 Boards's ("FASB") Accounting Standards Codification ("ASC") Topic 946 — Financial Services — Investment Companies.

A) SECURITY VALUATION — The Board of Trustees (the "Board") is responsible for the Fund's 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

40

Credit Suisse Strategic Income Fund
Notes to Financial Statements (continued)
April 30, 2019 (unaudited)

Note 2. Significant Accounting Policies (continued)

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 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.

41

Credit Suisse Strategic Income Fund

April 30, 2019 (unaudited)

Note 2. Significant Accounting Policies (continued)

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

•  Level 1  –  quoted prices in active markets for identical investments

•  Level 2  –  other significant observable inputs (including quoted prices for similar investments, interest rates, prepayment speeds, credit risk, etc.)

•  Level 3  –  significant unobservable inputs (including the Fund's own assumptions in determining the fair value of investments)

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

The following is a summary of the inputs used as of April 30, 2019 in valuing the Fund's assets and liabilities carried at 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

43

Credit Suisse Strategic Income Fund
Notes to Financial Statements (continued)
April 30, 2019 (unaudited)

Note 2. Significant Accounting Policies (continued)

instances, the fair value measurement is categorized in its entirety in the fair value hierarchy based on the least observable input that is significant to the fair value measurement. Additionally, changes in the market environment and other events that may occur over the life of the investments may cause the gains or losses ultimately realized on these investments to be different from the valuations used at the date of these financial statements.

For the six months ended April 30, 2019, $7,080,907 was transferred from Level 2 to Level 3 due to a lack of a pricing source supported by observable inputs, $6,780,765 was transferred from Level 3 to Level 2 and $320,912 was transferred from Level 3 to Level 1 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. For the six months ended April 30, 2019, the Fund's derivatives did not qualify for hedge accounting as they are held at fair value.

The following table presents the fair value and the location of derivatives within the Statement of Assets and Liabilities at April 30, 2019 and the effect of these derivatives on the Statement of Operations for the six months ended April 30, 2019.

Primary Underlying Risk	Derivative Assets		Derivative Liabilities		Realized Gain (Loss)		Change in Unrealized Appreciation (Depreciation)
Foreign currency exchange rate
Forward contracts	$	134,485	$	2,976	$	—	$	85,674

For the six months ended April 30, 2019, the Fund held an average monthly value on a net basis of $ 3,389,488 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,

44

Credit Suisse Strategic Income Fund
Notes to Financial Statements (continued)

Note 2. Significant Accounting Policies (continued)

agreements, collateral requirements, events of default and early termination. Termination events applicable to the Fund may occur upon a decline in the Fund's net assets below a specified threshold over a certain period of time.

The following table presents by counterparty the Fund's derivative assets, net of related collateral held by the Fund, at April 30, 2019:

Counterparty	Gross Amount of Derivative Assets Presented in Statement of Assets and Liabilities(a)		Financial Instruments and Derivatives Available for Offset			Non-Cash Collateral Received		Cash Collateral Received		Net Amount of Derivative Assets
Morgan Stanley	$	134,485	$	(2,976	)	$	—	$	—	$	131,509

The following table presents by counterparty the Fund's derivative liabilities, net of related collateral pledged by the Fund, at April 30, 2019:

Counterparty	Gross Amount of Derivative Liabilities Presented in Statement of Assets and Liabilities(a)		Financial Instruments and Derivatives Available for Offset			Non-Cash Collateral Pledged		Cash Collateral Pledged		Net Amount of Derivative Assets
Morgan Stanley	$	2,976	$	(2,976	)	$	—	$	—	$	—

^(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

45

Credit Suisse Strategic Income Fund
Notes to Financial Statements (continued)
April 30, 2019 (unaudited)

Note 2. Significant Accounting Policies (continued)

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. Certain expenses are class-specific expenses, vary by class and are charged only to that class. Income, expenses (excluding class-specific expenses) and realized/unrealized gains/losses are allocated proportionately to each class of shares based upon the relative net asset value of the outstanding shares of that class. 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 — Dividends from net investment income, if any, are declared daily and paid monthly. 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.

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

46

Credit Suisse Strategic Income Fund
Notes to Financial Statements (continued)
April 30, 2019 (unaudited)

Note 2. Significant Accounting Policies (continued)

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) FUTURES — The Fund may enter into futures contracts to the extent permitted by its investment policies and objectives. The Fund may use futures contracts to gain exposure to or hedge against changes in interest rates, equity and market price movements and/or currency risks. Upon entering into a futures contract, the Fund is required to deposit cash and/or pledge U.S. Government securities as initial margin with a Futures Commission Merchant ("FCM"). Subsequent payments, which are dependent on the daily fluctuations in the value of the underlying instrument, are made or received by the Fund each day (daily variation margin) and are recorded as unrealized gains or losses until the contracts are closed. When the contracts are closed, the Fund records a realized gain or loss equal to the difference between the proceeds from (or cost of) the closing transaction and the Fund's basis in the contract. Risks of entering into futures contracts for hedging purposes include the possibility that a change in the value of the contract may not correlate with the changes in the value of the underlying instruments. Futures have minimal counterparty credit risk because futures are exchange traded and the exchange's clearinghouse, as counterparty to all exchange-traded futures, guarantees the futures against default. In addition, the purchase of a futures contract involves the risk that the Fund could lose more than the original margin deposit and subsequent payments may be required for a futures transaction. The Fund's open futures contracts are disclosed in the Schedule of Investments. At April 30, 2019, the Fund had no open futures contracts.

The Commodity Exchange Act requires an FCM to segregate all customer transactions and assets from the FCM's proprietary activities. A customer's

47

Credit Suisse Strategic Income Fund
Notes to Financial Statements (continued)
April 30, 2019 (unaudited)

Note 2. Significant Accounting Policies (continued)

cash and other equity deposited with an FCM are considered commingled with all other customer funds subject to the FCM's segregation requirements. In the event of an FCM's insolvency, recovery may be limited to the Fund's pro-rata share of segregated customer funds available. It is possible that the recovery amount could be less than the total of cash and other equity deposited.

I) FORWARD FOREIGN CURRENCY CONTRACTS — A forward foreign currency exchange contract ("forward currency contract") is a commitment to purchase or sell a foreign currency at the settlement date at a negotiated rate. The Fund will enter into forward currency contracts primarily for hedging foreign currency risk. Forward currency contracts are valued at the prevailing forward exchange rate of the underlying currencies and unrealized gain/loss is recorded daily. On the settlement date of the forward currency contract, the Fund records a realized gain or loss equal to the difference between the value of the contract at the time it was opened and the value of the contract at the time it was closed. Certain risks may arise upon entering into forward currency contracts from the potential inability of counterparties to meet the terms of their contracts. The maximum counterparty credit risk to the Fund is measured by the unrealized gain on appreciated contracts. Additionally, when utilizing forward currency contracts to hedge, the Fund forgoes the opportunity to profit from favorable exchange rate movements during the term of the contract. The Fund's open forward currency contracts at April 30, 2019 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 on the Schedule of Investments. As of April 30, 2019, unfunded commitments were as follows:

Borrower	Maturity	Rate		Unfunded Commitment
Bulldog Purchaser, Inc.	09/04/26		3.875	$	30,865
Bulldog Purchaser, Inc.	09/05/25		3.750	$	35,746

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

48

Credit Suisse Strategic Income Fund
Notes to Financial Statements (continued)
April 30, 2019 (unaudited)

Note 2. Significant Accounting Policies (continued)

market value of foreign securities on loan (including any accrued interest thereon). The collateral is maintained thereafter at a value equal to at least 102% of the current market value of the securities on loan. The market value of loaned securities is determined at the close of each business day of the Fund and any additional required collateral is delivered to the Fund, or excess collateral returned by the Fund, on the next business day. Cash collateral received by the Fund in connection with securities lending activity may be pooled together with cash collateral for other funds/portfolios advised by Credit Suisse and may be invested in a variety of investments, including funds advised by SSB, the Fund's securities lending agent, or money market instruments. However, in the event of default or bankruptcy by the other party to the agreement, realization and/or retention of the collateral may be subject to legal proceedings.

SSB has been engaged by the Fund to act as the Fund's securities lending agent. 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. At April 30, 2019 and during the six months ended April 30, 2019, there were no securities out on loan.

L) OTHER — The high yield, fixed income securities in which the Fund invests will primarily consist of senior secured floating rate loans ("Senior Loans") issued by non-investment grade companies. Senior Loans are typically secured by specific collateral of the issuer and hold the most senior position in the issuer's capital structure. The interest rate on Senior Loans is periodically adjusted to a recognized base rate, typically the London Interbank Offered Rate ("LIBOR"). While these characteristics may reduce interest rate risk and mitigate losses in the event of borrower default, the Senior Loans in which the Fund invests have below investment grade credit ratings and thereby are considered speculative because of the significant credit risk of their issuers.

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.

49

Credit Suisse Strategic Income Fund
Notes to Financial Statements (continued)
April 30, 2019 (unaudited)

Note 2. Significant Accounting Policies (continued)

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 March 2017, the FASB issued Accounting Standards Update 2017-08, Receivables — Nonrefundable Fees and Other Costs (Subtopic 310-20): Premium Amortization On Purchased Callable Debt Securities ("ASU 2017-08"). The update shortens the amortization period for the premium on certain purchased callable debt securities to the earliest call date. ASU 2017-08 will be effective for annual periods beginning after December 15, 2018. Management is currently assessing the potential impact of these changes to future financial statements.

Also, 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 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.

N) SUBSEQUENT EVENTS — In preparing the financial statements as of April 30, 2019, management considered the impact of subsequent events for potential recognition or disclosure in these financial statements through the date of release of this report. No such events requiring recognition or disclosure were identified through the date of the release of this report.

Note 3. Transactions with Affiliates and Related Parties

Credit Suisse serves as investment adviser and co-administrator for the Fund.

Note 7. Contingencies

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

Credit Suisse Strategic Income Fund
Board Approval of Investment Management Agreement (unaudited)

In approving the amended and restated investment management agreement (the "Investment Management Agreement") and the sub-advisory agreement (the "Sub-Advisory Agreement") for the Credit Suisse Strategic Income Fund (the "Fund"), a series of Credit Suisse Opportunity Funds (the "Trust"), the Board of Trustees of the Trust (the "Board"), including all of the trustees who are not "interested persons" of the Trust as defined in the Investment Company Act of 1940 (the "Independent Trustees"), at a Special Telephonic Meeting held on November 7, 2018 where the Board discussed information and materials previously provided to them in connection with the renewal of the Investment Management Agreement and the Sub-Advisory Agreement, and at an in-person meeting held on November 12 and 13, 2018, considered the following factors:

Investment Management Fee Rates and Expenses

The Board reviewed and considered the contractual management fee rate of 0.84% of the Fund's average daily net assets ("Contractual Management Fee") for the Fund in light of the extent and quality of the management services provided by Credit Suisse Asset Management, LLC ("Credit Suisse"), as investment manager, and Credit Suisse Asset Management Limited (the "Sub-Adviser"), as sub-adviser. The Board noted that the compensation paid to the Sub-Adviser does not increase the fees or expenses otherwise incurred by the Fund. The Board also reviewed and considered the voluntary fee waivers currently in place for the Fund and considered the actual fee rate of 0.62% paid by the Fund after taking waivers and breakpoints into account (the "Net Management Fee"). The Board acknowledged that voluntary fee waivers could be discontinued at any time but had received assurances that such waivers would remain in place over the next year.

Additionally, the Board received and considered information comparing the Fund's Contractual Management Fee, Contractual Management Fee less waivers and/or reimbursements ("Net Management Fee") and the Fund's overall expenses with those of funds in both the relevant expense group ("Expense Group") and universe of funds ("Expense Universe") provided by Broadridge, an independent provider of investment company data. The Board noted that the Fund's Contractual Management Fee, Net Management Fee and overall expenses were comparable to those of its peers as presented in the Broadridge report. The Board was provided with a description of the methodology used to arrive at the funds included in the Expense Group and the Expense Universe.

55

Credit Suisse Strategic Income Fund
Board Approval of Investment Management Agreement (unaudited) (continued)

Nature, Extent and Quality of the Services under the Management Agreement

The Board received and considered information regarding the nature, extent and quality of services provided to the Fund by Credit Suisse under the Investment Management Agreement and by the Sub-Adviser under the Sub-Advisory Agreement. The Board also noted information received at regular meetings throughout the year related to the services rendered by Credit Suisse and the Sub-Adviser which, in addition to portfolio management and investment management services set forth in the Investment Management Agreement and the Sub-Advisory Agreement, also included credit analysis and research, supervising the day to day operations of the Fund's non-advisory functions which include accounting, administration, custody, transfer agent and other applicable third party service providers, overseeing and facilitating audits, overseeing the Fund's credit facility and supervising and/or preparing applicable Fund filings, disclosures and shareholder reports. The Board noted that the extensive investment management services provided by Credit Suisse included broad supervisory responsibility and oversight over other service providers to the Fund. The Board also considered Credit Suisse's compliance program with respect to the Fund. The Board noted that Credit Suisse reports to the Board about portfolio management and compliance matters on a periodic basis. The Board reviewed background information about Credit Suisse and the Sub-Adviser, including their respective Form ADV Part 2 — Disclosure Brochure and Brochure Supplement. The Board considered the background and experience of Credit Suisse's senior management and the expertise of, and the amount of attention given to the Fund by, senior personnel of Credit Suisse. In addition, the Board reviewed the qualifications, backgrounds and responsibilities of the portfolio management team primarily responsible for the day-to-day portfolio management of the Fund and the extent of the resources devoted to research and analysis of actual and potential investments, as well as the resources provided to them. The Board evaluated the ability of Credit Suisse and the Sub-Adviser, based on their resources, reputation and other attributes, to attract and retain qualified investment professionals including research, advisory, and supervisory personnel. The Board also received and considered information about the nature, extent and quality of services and fee rates offered to other Credit Suisse clients for comparable services. The Board acknowledged Credit Suisse's representation that the services provided to the Fund are more extensive than the services provided in connection with other types of accounts, such as separate accounts, offered by Credit Suisse and the services are also more extensive from those offered and provided to a sub-advised fund. The Board also considered that the

56

Credit Suisse Strategic Income Fund
Board Approval of Investment Management Agreement (unaudited) (continued)

services provided by Credit Suisse have expanded over time as a result of regulatory and other developments.

In approving the renewal of the Sub-Advisory Agreement, the Board considered the benefits of retaining Credit Suisse's affiliate as the Fund's Sub-Adviser and the Sub-Adviser's investment style.

Fund Performance

The Board received and considered performance results of the Fund over the previous year as well as over longer time periods, along with comparisons both to the relevant performance group ("Performance Group") and universe of funds ("Performance Universe") for the Fund. The Board was provided with a description of the methodology used to arrive at the funds included in the Performance Group and the Performance Universe. The Board noted that the Fund outperformed its Performance Universe for the one-year period reported, as well as over various longer investment periods reported. The Board also considered the investment performance of the Fund relative to its stated objectives.

Credit Suisse Profitability

The Board received and considered a profitability analysis of Credit Suisse based on the fees payable under the Investment Management Agreement for the Fund, including any fee waivers, as well as other relationships between the Fund on the one hand and Credit Suisse affiliates on the other. The Board deliberations also reflected Credit Suisse's methodology for allocating costs to the Fund, recognizing that cost allocation methodologies are inherently subjective. The Board also received net profitability information for the other funds in the Credit Suisse family of funds, which include both open-end and closed-end funds. The Board also reviewed Credit Suisse's profit margin as reflected in the profitability analysis, as well as reviewing profitability in light of appropriate court cases and the services rendered to the Fund.

Economies of Scale

The Board considered information regarding whether there have been economies of scale with respect to the management of the Fund, whether the Fund has appropriately benefited from any economies of scale, and whether there is potential for realization of any further economies of scale. The Board noted that as the Fund continues to grow, additional efficiencies and economies

57

Credit Suisse Strategic Income Fund
Board Approval of Investment Management Agreement (unaudited) (continued)

of scale potentially could be realized. The Board also noted the voluntary expense limitations currently in place between the Fund and Credit Suisse. The Board received information regarding Credit Suisse's historical profitability, including Credit Suisse's costs in providing services.

Other Benefits to Credit Suisse

The Board considered other benefits received by Credit Suisse, the Sub-Adviser and their affiliates as a result of their relationship with the Fund. Such benefits include, among others, benefits potentially derived from an increase in Credit Suisse's and the Sub-Adviser's businesses as a result of their relationship with the Fund (such as the ability to market to shareholders other financial products offered by Credit Suisse and its affiliates) and the fees paid to an affiliate of Credit Suisse for distribution services.

The Board considered the standards Credit Suisse and the Sub-Adviser applied in seeking best execution and their policies and practices regarding soft dollars for the Fund and considered Credit Suisse's method for allocating portfolio investment opportunities among its advisory clients.

Other Factors and Broader Review

As discussed above, the Board reviewed detailed materials received from Credit Suisse as part of the annual approval process. The Board also reviews and assesses the quality of the services that the Fund receives throughout the year. In this regard, the Board reviews reports of Credit Suisse at least quarterly, which include, among other things, detailed portfolio and market reviews, detailed fund performance reports, and Credit Suisse's compliance procedures.

Conclusions

In selecting Credit Suisse and the Sub-Adviser, and approving the renewal of the Investment Management Agreement and the investment management fee under such agreement and the Sub-Advisory Agreement, the Board concluded that:

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

58

Credit Suisse Strategic Income Fund
Board Approval of Investment Management Agreement (unaudited) (continued)

•  The Board was satisfied with the nature, extent and quality of the investment management services provided to the Fund by Credit Suisse and the Sub-Adviser and that, based on dialogue with management and counsel, the services provided by Credit Suisse under the Investment Management Agreement and the Sub-Adviser under the Sub-Advisory Agreement are typical of, and consistent with, those provided to similar mutual funds by other investment managers.

•  In light of the costs of providing investment management and other services to the Fund and Credit Suisse's ongoing commitment to the Fund and willingness to waive fees, Credit Suisse's net profitability based on fees payable under the Investment Management Agreement, as well as other ancillary benefits that Credit Suisse and its affiliates received, were considered reasonable.

•  In light of the information received and considered by the Board, the Fund's current fee structure was considered reasonable.

No single factor reviewed by the Board was identified by the Board as the principal factor in determining whether to approve the renewal of the Investment Management Agreement and Sub-Advisory Agreement. The Independent Trustees were advised by separate independent legal counsel throughout the process.
