Credit Suisse Floating Rate High Income Fund
Semiannual Investment Adviser's Report
April 30, 2018 (unaudited)

May 18, 2018

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, 2018.

Performance Summary
11/1/2017 – 4/30/2018

Fund & Benchmark	Performance
Class I1		1.79	%
Class A1,2		1.81	%
Class C1,2		1.43	%
Credit Suisse Leveraged Loan Index3		2.59	%

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 for the asset class

The six-month period ended April 30, 2018 was a positive one for the senior secured loan asset class. The Credit Suisse Leveraged Loan Index (the "Index"), the Fund's benchmark, returned 2.59% for the period. The discount margin for senior loans, using a three-year average life assumption, tightened 0.39% to end the period at +382 basis points. Principal appreciation was a contributor to performance, as the price of the Index increased 0.68% to finish the period at $98.23.

Despite volatility in most risk assets, there has been continued interest in the leveraged loan asset class. According to Standard & Poor's, there has been robust CLO issuance and four consecutive months of mutual fund flows into the market. CLO creation has exceeded expectations with more than $65.7 billion of issuance during the period. Although November and December experienced heavy outflows of $5.32 billion, $6.13 billion flowed back in from January through April to leave mutual fund flows roughly flat for the period.

Issuers have reacted to the market strength and heightened investor interest with significant issuance. During the six-month period, there has been $227 billion of issuance net of repricing activity. On a calendar year basis, although 2018 is lagging the record gross issuance seen in 2017, it is slightly ahead on a net basis compared to the same period last year. CLO issuance and institutional and retail interest in the asset class have been strong and, therefore, the asset class returns have continued to be positive.

Fundamentals continue to be strong, with the par-weighted default rate ending the period at 2.35% — well below the historical range of 3.0-3.5% — as reported by JPMorgan.

From a quality point of view, returns were positive across rating classes within the Index. Distressed (CC, C, and Default) posted the highest returns, at 5.54%, followed by Split BB loans, which returned 3.93% during the period. Single B and Split BBB rated loans underperformed with respective returns of 1.85% and 2.09%.

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

For the six-month period ended April 30, 2018, the Fund underperformed the benchmark. Although security selection in oil contributed to relative performance, security selection in BB-rated securities and the broadcasting and entertainment sector detracted from performance. From an asset class perspective, the Fund's weightings in high yield and asset-backed energy also hurt relative performance.

Federal Reserve rate hikes, continued institutional and prime fund inflows, as well as heightened CLO formation have been supportive of the loan asset class. We believe that this, combined with steady economic fundamentals and low intermediate default expectations (outside sectors like retail that are experiencing secular shifts), should translate to positive demand for the asset class.

Further, although the potential for global volatility in risk assets may persist due to trade tensions and geopolitical headlines, economic performance looks to be supportive of continued interest rate increases which, in turn, are favorable for the floating rate nature of the loan asset class.

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, 2018; these views and Fund holdings may have changed subsequent to these dates. Nothing in this document is a recommendation to purchase or sell securities.

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, 2018.

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, 2018 (unaudited)

Note 1. Organization

Credit Suisse Floating Rate High Income Fund (the "Fund"), a series of the 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, which reflect the differences in the range of services provided to them. 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 accounting principles generally accepted 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 Accounting Standard Codification ("ASC") Topic 946 — Financial Services — Investment Companies.

A) SECURITY VALUATION — 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

39

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

Note 2. Significant Accounting Policies (continued)

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 of Trustees (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, the Fund values these securities as determined in accordance with procedures approved and established by the Board.

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

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

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

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

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

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

The following is a summary of the inputs used as of April 30, 2018 in valuing the Fund's assets and liabilities carried at fair value:

Assets	Level 1		Level 2		Level 3		Total
Investments in Securities
Bank Loans	$	—	$	2,781,965,118	$	293,587,490	$	3,075,552,608

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 Asset Management LLC, the Fund's investment adviser ("Credit Suisse" or the "Adviser") 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

42

Credit Suisse Floating Rate High Income Fund
Notes to Financial Statements (continued)
April 30, 2018 (unaudited)

Note 2. Significant Accounting Policies (continued)

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, 2018, there were no transfers between Level 1 and Level 2, but there was $97,277,861 transferred from Level 2 to Level 3 due to a lack of pricing source supported by observable inputs and $75,631,101 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, 2018, 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, 2018 and the effect of these derivatives on the Statement of Operations for the six months ended April 30, 2018.

Primary Underlying Risk	Derivative Assets		Derivative Liabilities		Realized Gain (Loss)		Change in Unrealized Appreciation (Depreciation)
Foreign currency exchange rate forward contracts		$93,668		$6,366,931		$(6,750,689)		$(1,377,536)

For the six months ended April 30, 2018, the Fund held an average monthly value on a net basis of $275,182,614 in forward foreign currency contracts.

Note 2. Significant Accounting Policies (continued)

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, 2018:

Counterparty	Gross Amount of Assets Presented in the 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	$	93,668	$	(93,668	)	$	—	$	—	$	—

The following table presents by counterparty the Fund's derivative liabilities, net of related collateral pledged by the Fund, at April 30, 2018:

Counterparty	Gross Amount of Liabilities Presented in the Statement of Assets and Liabilities(a)		Financial Instruments and Derivatives Available for Offset			Non-Cash Collateral Pledged		Cash Collateral Pledged		Net Amount of Derivative Liabilities
Morgan Stanley	$	6,366,931	$	(93,668	)	$	—	$	—	$	6,273,263

^(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 are translated into U.S. dollar amounts at the current exchange rate at the end of the period. 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,

44

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

Note 2. Significant Accounting Policies (continued)

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 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,

45

Credit Suisse Floating Rate High Income Fund
Notes to Financial Statements (continued)
April 30, 2018 (unaudited)

Note 2. Significant Accounting Policies (continued)

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) SHORT-TERM INVESTMENTS — The Fund, together with other funds/portfolios advised by Credit Suisse, pools available cash into a short-term variable rate time deposit issued by State Street Bank and Trust Company ("SSB"), the Fund's custodian. The short-term time deposit issued by SSB is a variable rate account classified as a short-term investment.

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 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, 2018 are disclosed in the Schedule of Investments.

Note 2. Significant Accounting Policies (continued)

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, 2018, unfunded commitments were as follows:

Borrower	Maturity	Rate		Unfunded Commitment
Mitchell International, Inc.	11/29/24		3.250	$	169,104

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 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, 2018, the Fund had investment securities on loan with a fair value of $8,465,807. Collateral received for securities loaned and a related liability of $8,605,428 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, 2018, 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

47

Note 2. Significant Accounting Policies (continued)

lending income is accrued as earned. During the six months ended April 30, 2018, total earnings from the Fund's investment in cash collateral received in connection with securities lending arrangements was $53,280, of which $11,895 was rebated to borrowers (brokers). The Fund retained $31,031 in income from the cash collateral investment, and SSB, as lending agent, was paid $10,354.

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.

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 October 2016, the U.S. Securities and Exchange Commission adopted new rules and amended existing rules (together, "final rules") intended to modernize the reporting and disclosure of information by registered investment companies. In part, the final rules amend Regulation S-X and require standardized, enhanced disclosure about derivatives in investment company financial statements, as well as other amendments. The compliance date for the amendments to Regulation S-X is August 1, 2017. The Fund has adopted the amendments to Regulation S-X and upon evaluation, has concluded that the amendments do not materially impact the financial statements. However, as required, additional or enhanced disclosure has been included.

M) SUBSEQUENT EVENTS — In preparing the financial statements as of April 30, 2018, 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 annual 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. For the six months ended April 30, 2018, investment advisory and administration fees earned and voluntarily waived by Credit Suisse were $10,900,588 and $1,160,392, respectively.

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, 2018, co-administrative services fees earned by SSB (including out-of-pocket expenses) with respect to the Fund were $267,722.

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, 2018, the Fund paid Rule 12b-1 distribution fees of $347,023 for Class A shares and $581,283 for Class C shares. For the period November 1, 2016 through December 15, 2017, the Fund paid Rule 12b-1 distribution fees of $1,211 for Class B 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, 2018, the Fund paid $476,110 which is included within transfer agent fees in the Statement of Operations.

49

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

For the six months ended April 30, 2018, CSSU and its affiliates advised the Fund that they retained $12,529 from commissions earned on the sale of the Fund's Class A shares. There were no commissions earned on the sale of Class C shares.

The Fund from time to time purchases or sells loan investments in the secondary market through Credit Suisse or its affiliates acting in the capacity as broker-dealer. Credit Suisse or its affiliates may have acted in some type of agent capacity to the initial loan offering prior to such loan trading in the secondary market.

Note 4. Line of Credit

The Fund, 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 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, 2018 and for the six months ended April 30, 2018, the Fund had no borrowings outstanding under the Credit Facility.

Note 5. Purchases and Sales of Securities

For the six months ended April 30, 2018, purchases and sales of investment securities (excluding short-term investments) were $1,088,898,144 and $899,670,814, respectively.

Note 6. Capital Share Transactions

Note 6. Capital Share Transactions (continued)

On April 30, 2018, 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		61	%
Class A		4		62	%
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 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.

Board Approval of Investment Management Agreement (unaudited)

In approving the amended and restated 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 meeting held on November 13 and 14, 2017, 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 Board also reviewed and considered the voluntary fee waivers currently in place for the Fund and considered the actual fee rate of 0.64% 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 Management Agreement. The Board also noted information received at regular meetings throughout the year related to the services rendered by Credit Suisse. The Board noted that the extensive investment management services provided by Credit Suisse included broad supervisory responsibility and oversight over

53

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

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 Fund is different from other types of accounts offered by Credit Suisse and the services are different from those offered 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 time, 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 considered the solid investment performance of the Fund over various investment periods relative to its stated objectives as well as the performance of the Fund relative to its peers.

Credit Suisse Profitability

The Board received and considered a profitability analysis of Credit Suisse based on the fees payable under the 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

54

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

also reflected Credit Suisse's methodology for allocating costs to the Fund, recognizing that cost allocation methodologies are inherently subjective. The Board also received profitability information for the other funds in the Credit Suisse family of 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 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

55

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

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 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 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, Credit Suisse's profitability based on fees payable under the 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 Management Agreement. The Independent Trustees were advised by separate independent legal counsel throughout the process.

Credit Suisse Managed Futures Strategy Fund
Semiannual Investment Adviser's Report
April 30, 2018 (unaudited)

May 18, 2018

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, 2018.

Performance Summary
11/1/2017 – 4/30/2018

Fund & Benchmark	Performance
Class I1		-5.82	%
Class A1,2		-5.96	%
Class C1,2		-6.36	%
Credit Suisse Managed Futures Liquid Index3		-6.09	%

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: A challenging period for managed futures

The six-month period ended April 30, 2018 was a challenging one for managed futures funds, as represented by the Credit Suisse Managed Futures Hedge Fund Index, which returned -2.54% over the period. By comparison, the Credit Suisse Managed Futures Liquid Index, the Fund's benchmark (the "Benchmark"), returned -6.09% over the same period.

In general, the managed futures industry struggled over the last year, as a number of underlying markets experienced sharp medium- to long-term reversals following January's rally.

Strategic Review and Outlook: Relative outperformance despite many market reversals

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.

For the six-month period ended April 30, 2018, the Fund's I shares and A shares outperformed the Benchmark.

Fixed income positions were the lone contributor to Fund performance. Outside of US Treasuries, underlying markets contended with a combination of conflicting measures of inflation, central bank policies and idiosyncratic political risks that suppressed any sustained market trend and increased vulnerability to frequent reversals. The Fund was able to take advantage of the upward trend in

1

Credit Suisse Managed Futures Strategy Fund
Semiannual Investment Adviser's Report (continued)
April 30, 2018 (unaudited)

Treasury yields, fueled in part by the large expected debt issuance calendar and the prospect of accelerating inflation.

Equity positions were the largest detractor from Fund performance over the period. Last year's equity market uptrend continued into the new year, and gathered momentum following the successful passage of the US Tax Reform bill. The subsequent market correction in February offset previous gains and caused a significant reduction of long bias to the underlying markets. The volatile, sideways market that followed created an added drag on performance.

Commodities were the second largest detractor from performance over the period. Profits came from the emerging long energy trend, led by surging crude prices as the global supply overhang continued to ease and heightened geopolitical risks elevated the prospect of a potential supply shock. However, this only partially offset losses led by the agriculture and precious metals markets. Like the fixed income markets, precious metals fluctuated frequently, as inflation, central bank policy, and heightened geopolitical risks generated conflicting signals. The reversal of the persistent downward trend in agriculture markets was motivated by various weather-related supply shocks that caused meaningful shifts in short-term price dynamics.

Currencies also detracted from Fund performance, as the asset class reflected the broad US Dollar reversal that occurred over the period. Long positions against the US Dollar profited during the protracted decline that lasted through January, reflecting the increasing concerns around inflation and debt that weighed on the US Dollar. However, the rise in Treasury yields gathered momentum and lent support to the currency, which incurred losses during the reversal of the trend.

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

2

Credit Suisse Managed Futures Strategy Fund
Semiannual Investment Adviser's Report (continued)
April 30, 2018 (unaudited)

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, 2018; 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 entered into a written contract to limit 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 through at least February 28, 2019. 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 (10.92)%. Total return for the Fund's Class C shares for the reporting period, based on redemption value including Contingent Deferred Sales Charge ("CDSC") of 1.00%, was (7.30)%.

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 to seek 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 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, 2018.

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.

Note 1. Organization

Credit Suisse Managed Futures Strategy Fund (the "Fund"), a series of the 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 result that corresponds 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 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, 2018, the Fund held $11,434,621 in the Subsidiary, representing 3.8% of the Fund's consolidated net assets. For the six months ended April 30, 2018, the net realized loss on securities and other financial instruments held in the Subsidiary was $5,461,885.

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, which reflect the differences in the range of services provided to them. 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 Accounting Standards Codification ("ASC") Topic 946 — Financial Services — Investment Companies.

A) SECURITY VALUATION — The net asset value of the Fund is determined daily as of the close of regular trading on the New York Stock Exchange, Inc. (the "Exchange") on each day the Exchange is open for business. The valuations for fixed income securities (which may include, but are not limited to, corporate, government, municipal, mortgage-backed, collateralized mortgage obligations and asset-backed securities) and certain derivative instruments are typically the prices supplied by independent third party pricing services, which may use market prices or broker/dealer quotations or a variety of valuation techniques and methodologies. The independent third party pricing services use inputs that are observable such as issuer details, interest rates, yield curves, prepayment speeds, credit risks/spreads, default rates and quoted prices for similar securities. These pricing services generally price fixed income securities assuming orderly transactions of an institutional "round lot" size, but some trades occur in smaller "odd lot" sizes which may be effected at lower prices than institutional round lot trades. Structured note agreements are valued in accordance with a dealer-supplied valuation based on changes in the value of the underlying index. Futures contracts are valued daily at the settlement price established by the board of trade or exchange on which they are traded. Forward contracts are valued at the London closing spot rates and the London closing forward point rates on a daily basis. The currency forward contract pricing model derives the differential in point rates to the expiration date of the forward and calculates its present value. Equity securities for which market quotations are available are valued at the last reported sales price or official closing price on the primary market or exchange on which they trade. The Fund may utilize a service provided by an independent third party which has been approved by the Board of Trustees (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

Note 2. Significant Accounting Policies (continued)

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, the Fund values these securities as determined in accordance with procedures approved and established by the Board.

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

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

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

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

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

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

The following is a summary of the inputs used as of April 30, 2018 in valuing the Fund's assets and liabilities carried at fair value:

Assets	Level 1		Level 2		Level 3		Total
Investments in Securities
United States Treasury Obligations	$	—	$	198,554,757	$	—	$	198,554,757

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

For the six months ended April 30, 2018, 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, 2018, 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, 2018 and the effect of these derivatives on the Consolidated Statement of Operations for the six months ended April 30, 2018.

The notional amount of futures contracts and swap contracts open at April 30, 2018 is reflected in the Consolidated Schedule of Investments. For the six months ended April 30, 2018, the Fund held average monthly notional values on a net basis of $988,709,785, $384,673,671 and $145,559,798 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.

^(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, 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

19

Credit Suisse Managed Futures Strategy Fund
Notes to Consolidated Financial Statements (continued)
April 30, 2018 (unaudited)

Note 2. Significant Accounting Policies (continued)

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 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

20

Notes to Consolidated Financial Statements (continued)
April 30, 2018 (unaudited)

Note 2. Significant Accounting Policies (continued)

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) SHORT-TERM INVESTMENTS — The Fund, together with other funds/portfolios advised by Credit Suisse, pools available cash into a short-term variable rate time deposit issued by State Street Bank and Trust Company ("SSB"), the Fund's custodian. The short-term time deposit issued by SSB is a variable rate account classified as a short-term investment.

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 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, 2018, the amount of restricted cash held at brokers related to open futures contracts was $16,772,371.

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

21

Credit Suisse Managed Futures Strategy Fund
Notes to Consolidated Financial Statements (continued)
April 30, 2018 (unaudited)

Note 2. Significant Accounting Policies (continued)

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.

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

22

Credit Suisse Managed Futures Strategy Fund
Notes to Consolidated Financial Statements (continued)
April 30, 2018 (unaudited)

Note 2. Significant Accounting Policies (continued)

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, 2018, the amount of restricted cash held at brokers related to open swap contracts was $7,990,000.

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, 2018 and during the six months ended April 30, 2018, there were no securities out on loan.

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

23

Note 2. Significant Accounting Policies (continued)

approximates their carrying value as recorded in the Fund's Consolidated Statement of Assets and Liabilities.

K) RECENT ACCOUNTING PRONOUNCEMENTS — In October 2016, the U.S. Securities and Exchange Commission adopted new rules and amended existing rules (together, "final rules") intended to modernize the reporting and disclosure of information by registered investment companies. In part, the final rules amend Regulation S-X and require standardized, enhanced disclosure about derivatives in investment company financial statements, as well as other amendments. The compliance date for the amendments to Regulation S-X is August 1, 2017. The Fund has adopted the amendments to Regulation S-X and upon evaluation, has concluded that the amendments do not materially impact the financial statements. However, as required, additional or enhanced disclosure has been included.

L) SUBSEQUENT EVENTS — In preparing the financial statements as of April 30, 2018, 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 annual rate of 1.04% of the Fund's average daily net assets. For the six months ended April 30, 2018, investment advisory and administration fees earned and fees waived/expenses reimbursed by Credit Suisse were $1,805,269 and $36,176, 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 three years after the end of the fiscal year 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, 2019.

Totals	$	201,677	$	76,618	$	14,388	$	110,671

*  The Subsidiary is 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, 2018, co-administrative services fees earned by SSB (including out-of-pocket expenses) with respect to the Fund were $23,768.

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 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, 2018, the Fund paid Rule 12b-1 distribution fees of $120,805 for Class A shares and $16,983 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, 2018, the Fund paid $47,910, which is included within transfer agent fees in the Consolidated Statement of Operations.

For the six months ended April 30, 2018, CSSU and its affiliates earned no commissions on the sale of the Fund's Class A shares and Class C shares.

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 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, 2018 and during the six months ended April 30, 2018, the Fund had no borrowings outstanding under the Credit Facility.

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.

27

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

In approving the amended and restated 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 meeting held on November 13 and 14, 2017, 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 Board also considered that Credit Suisse has entered into an 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, 2019.

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 Management Agreement. The Board also noted information received at regular meetings throughout the year related to the services rendered by Credit Suisse. 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

28

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

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 Fund is different from other types of accounts offered by Credit Suisse and the services are different from those offered 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 time, 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 considered the positive investment performance of the Fund since its inception relative to its stated objectives as well as the performance of the Fund relative to its peers.

Credit Suisse Profitability

The Board received and considered a profitability analysis of Credit Suisse based on the fees payable under the 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

29

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

Board also received profitability information for the other funds in the Credit Suisse family of 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 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 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 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 profitability based on fees payable under the 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 Management Agreement. The Independent Trustees were advised by separate independent legal counsel throughout the process.

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, 2018.

Performance Summary
11/1/2017 – 4/30/2018

Fund & Benchmark	Performance
Class I1		0.21	%
Class A1,2		0.02	%
Class C1,2		0.85	%(a)
Credit Suisse Hedge Fund Index3		1.54	%
Credit Suisse Liquid Alternative Beta Index4		0.00	%

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 multi-alternative strategies

The six-month period ended April 30, 2018 was an interesting one with the Credit Suisse Hedge Fund Index, the Fund's primary benchmark, returning +1.54%.

Within the hedge fund universe, fixed income arbitrage funds yielded the strongest performance over the period — benefitting from both strong directional moves in global interest rates and elevated levels of rate volatility that afforded more tactical opportunities.

Market neutral equity funds also performed well, due in part to their net neutral positioning during the market correction. Momentum factor emergence at the beginning of the year also augmented profits.

Managed futures funds, however, were the worst performers over the period, suffering from sharp reversals in markets that had previously exhibited persistent trends. Particularly notable was the reversal in equity markets following a period of extraordinarily low volatility that had skewed equity positioning. Losses also occurred due to the reversal in the protracted decline of agriculture markets along with range bound precious metals prices that tracked moves in inflation.

^(a)  For the period November 1, 2017 through February 14, 2018. Class C was redeemed on February 15, 2018 and currently has no shareholders.

Strategic Review and Outlook: Positives and negatives following the market's correction

For the six-month period ended April 30, 2018, the Fund's I shares outperformed the Credit Suisse Liquid Alternative Beta Index and underperformed the Credit Suisse Hedge Fund Index. The Fund follows a multi-strategy methodology and benefitted from exposure across different markets and asset classes where diversification was highlighted during the February market correction.

In terms of asset class returns, fixed income, taking advantage of the strong directional market moves over the period, contributed most significantly to returns. This was followed by equity strategies. Commodities, foreign exchange, multi-asset and volatility strategies all detracted from Fund performance in similar magnitude.

Within equities, value was the most profitable style, as broad long market exposures took advantage of the strong rally ahead of the correction and were then complemented by select long and short positions in certain sectors that contributed following the selloff. Tilts toward technology and small cap equities in developed markets were particularly profitable.

Fixed income trend/momentum was the largest contributing strategy, as the expected repatriation of US Dollars resulting from US Tax Reform combined with US Federal Reserve hike expectations to send short-term funding rates higher across the period.

Equity liquidity/insurance strategies yielded the largest losses over the period, as idiosyncratic deal risk and a soured regulatory environment caused significant deal spread widening.

Volatility liquidity/insurance strategies also incurred losses, following the unprecedented spike in volatility following February's selloff. The resonating uncertainty supported elevated levels of volatility that offered some value opportunities through expected reversion.

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.

The Fund has no obligation to update or revise forward-looking statements.

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, 2018.

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 Paid per $1,000*	$	4.96		$	6.21
	Class I			Class A
Annualized Expense Ratios*		0.99	%		1.24	%

*  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 Multialternative Strategy Fund (the "Fund"), a series of the 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 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, 2018, the Fund held $5,358,712 in the Subsidiary, representing 5.1% of the Fund's consolidated net assets. For the six months ended April 30, 2018, the net realized gain on securities and other financial instruments held in the Subsidiary was $793,161.

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, which reflect the differences in the range of services provided to them. 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. Class C was redeemed on February 15, 2018 and currently has no shareholders.

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 Accounting Standards Codification ("ASC") Topic 946 — Financial Services — Investment Companies.

A) SECURITY VALUATION — 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 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

Notes to Consolidated Financial Statements (continued)

Note 2. Significant Accounting Policies (continued)

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 of Trustees (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, the Fund values these securities as determined in accordance with procedures approved and established 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.

As of April 30, 2018, the amount of Level 3 securities that were measured at fair value amounted to less than 0.01% of net assets. For the six months ended April 30, 2018, 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, 2018, the Fund's derivatives did not qualify for hedge accounting as they are held at fair value.

The following table presents by counterparty the Fund's derivative liabilities, net of related collateral pledged by the Fund, at April 30, 2018:

Counterparty	Gross Amount of Liabilities Presented in the Consolidated Statement of Assets and Liabilities(a)		Financial Instruments and Derivatives Available for Offset			Non-Cash Collateral Pledged		Cash Collateral Pledged(b)		Net Amount of Derivative Liabilities

^(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 are translated into U.S. dollar amounts at the current exchange rate at the end of the period. 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

43

Credit Suisse Multialternative Strategy Fund
Notes to Consolidated Financial Statements (continued)
April 30, 2018 (unaudited)

Note 2. Significant Accounting Policies (continued)

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 "Code"), and to make the requisite distributions to its shareholders, which will be sufficient to relieve it from federal income and excise taxes.

44

Credit Suisse Multialternative Strategy Fund
Notes to Consolidated Financial Statements (continued)
April 30, 2018 (unaudited)

Note 2. Significant Accounting Policies (continued)

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) SHORT-TERM INVESTMENTS — The Fund, together with other funds/portfolios advised by Credit Suisse, pools available cash into a short-term variable rate time deposit issued by State Street Bank and Trust Company

45

Credit Suisse Multialternative Strategy Fund
Notes to Consolidated Financial Statements (continued)
April 30, 2018 (unaudited)

Note 2. Significant Accounting Policies (continued)

("SSB"), the Fund's custodian. The short-term time deposit issued by SSB is a variable rate account classified as a short-term investment.

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, 2018, 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 to the difference between the proceeds from (or cost of) the closing transaction

46

Credit Suisse Multialternative Strategy Fund
Notes to Consolidated Financial Statements (continued)
April 30, 2018 (unaudited)

Note 2. Significant Accounting Policies (continued)

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, 2018, the amount of restricted cash held at brokers related to open futures contracts was $2,621,268.

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, 2018 are disclosed in the Consolidated Schedule of Investments.

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

47

Credit Suisse Multialternative Strategy Fund
Notes to Consolidated Financial Statements (continued)
April 30, 2018 (unaudited)

Note 2. Significant Accounting Policies (continued)

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.

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

48

Credit Suisse Multialternative Strategy Fund
Notes to Consolidated Financial Statements (continued)
April 30, 2018 (unaudited)

Note 2. Significant Accounting Policies (continued)

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, 2018, the amounts of restricted cash held at brokers related to open swap contracts and centrally cleared swaps for the Fund were $5,676,560 and $0, respectively.

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 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

49

Credit Suisse Multialternative Strategy Fund
Notes to Consolidated Financial Statements (continued)
April 30, 2018 (unaudited)

Note 2. Significant Accounting Policies (continued)

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, 2018, the amount of restricted cash held at brokers related to option contracts was $11,732,027.

For the six months ended April 30, 2018, transactions for written options on securities, interest rate swaps and futures were as follows:

	Number of Contracts			Premium Received
Written Options, outstanding as of October 31, 2017		123		$	155,253
Options written		841			1,999,842
Options bought back		(208	)		(512,741	)
Options exercised		—			—
Options expired		(676	)		(1,380,437	)
Written Options, outstanding as of April 30, 2018		80		$	261,917

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, 2018, the Fund had investment securities on loan with a

50

Credit Suisse Multialternative Strategy Fund
Notes to Consolidated Financial Statements (continued)
April 30, 2018 (unaudited)

Note 2. Significant Accounting Policies (continued)

fair value of $12,681,203. Collateral received for securities loaned and a related liability of $12,955,578 are presented gross in the Consolidated 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, 2018, the value of the related collateral exceeded the value of the securities loaned.

During the six months ended April 30, 2018, total earnings from the Fund's investment in cash collateral received in connection with securities lending arrangements was $12,434, of which $4,496 was rebated to borrowers (brokers). The Fund retained $5,952 in income from the cash collateral investment, and SSB, as lending agent, was paid $1,986. 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

51

Credit Suisse Multialternative Strategy Fund
Notes to Consolidated Financial Statements (continued)
April 30, 2018 (unaudited)

Note 2. Significant Accounting Policies (continued)

markets and may experience greater volatility than a Fund that is more broadly diversified geographically.

P) RECENT ACCOUNTING PRONOUNCEMENTS — In October 2016, the U.S. Securities and Exchange Commission adopted new rules and amended existing rules (together, "final rules") intended to modernize the reporting and disclosure of information by registered investment companies. In part, the final rules amend Regulation S-X and require standardized, enhanced disclosure about derivatives in investment company financial statements, as well as other amendments. The compliance date for the amendments to Regulation S-X is August 1, 2017. The Fund has adopted the amendments to Regulation S-X and upon evaluation, has concluded that the amendments do not materially impact the financial statements. However, as required, additional or enhanced disclosure has been included.

Q) SUBSEQUENT EVENTS — In preparing the financial statements as of April 30, 2018, 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, 2018, investment advisory and administration fees earned and fees waived/expenses reimbursed by Credit Suisse were $540,461 and $418,307, 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, 1.10% of the Fund's average daily net assets for Class A shares and 1.85% 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 three years after the end of the fiscal year 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, 2019.

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, 2018, co-administrative services fees earned by SSB (including out-of-pocket expenses) with respect to the Fund were $15,684.

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 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, 2018, the Fund paid Rule 12b-1 distribution fees of $1,623 for Class A shares and $126 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, 2018, the Fund paid $8,820, which is included within transfer agent fees in the Consolidated Statement of Operations.

For the six months ended April 30, 2018, CSSU and its affiliates advised the Fund that there were no commissions earned on the sale of Class A and Class C 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

53

Note 4. Line of Credit (continued)

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 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, 2018 and during the six months ended April 30, 2018, the Fund had no borrowings outstanding under the Credit Facility.

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.

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

In approving the amended and restated 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 meeting held on November 13 and 14, 2017, 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 Board also considered that Credit Suisse entered into an 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, 2019.

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 Management Agreement. The Board also noted information received at regular meetings throughout the year related to the services rendered by Credit Suisse. 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

56

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

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 Fund is different from other types of accounts offered by Credit Suisse and the services are different from those offered 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 time, 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 considered the investment performance of the Fund relative to its stated objectives as well as the performance of the Fund relative to its peers.

Credit Suisse Profitability

The Board received and considered a profitability analysis of Credit Suisse based on the fees payable under the 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

57

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

Board also received profitability information for the other funds in the Credit Suisse family of 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 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 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 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 profitability based on fees payable under the 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 Management Agreement. The Independent Trustees were advised by separate independent legal counsel throughout the process.

May 18, 2018

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, 2018.

Performance Summary
11/1/2017 – 4/30/18

Fund & Benchmark	Performance
Class I1		1.36	%
Class A1,2		1.24	%
Class C1,2		0.86	%
ICE BofAML 3-Month US Treasury Bill Index3		0.68	%

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 volatile period for risk assets

The six-month period ended April 30, 2018 was a volatile one for below investment grade credit asset classes. Risk assets experienced heightened volatility, as the Federal Reserve raised the federal funds rate, the 10-year U.S. Treasury saw widening, and geopolitical headlines increased. In this context, the Credit Suisse Leveraged Loan Index returned 2.59%, while the high yield asset class, as represented by the ICE BofAML US High Yield Constrained Index, returned -0.23%. In comparison, the ICE BofAML 3-Month US Treasury Bill Index (the "Benchmark"), the Fund's benchmark, returned 0.68% for the period.

Heading into the end of 2017, global equity and credit markets were strong with macroeconomic stability and positive sentiment toward the U.S. tax reform. Rates have increased in 2018, with the U.S. 10-year Treasury widening from 2.41% to 2.94% between December 31, 2017 and April 30, 2018. This has put pressure on fixed income assets with duration — particularly higher quality, longer duration high yield bonds. Leveraged loans, with their shorter duration profile, fared much better, as the technical environment continued to be positive for the asset class. In fact, CLO creation has exceeded expectations with more than $65.7 billion of issuance during the period, while prime mutual funds had inflows of $810 million.

Credit Suisse Strategic Income Fund
Semiannual Investment Adviser's Report (continued)
April 30, 2018 (unaudited)

Fundamentals have been stable, with the leveraged loans par-weighted default rate ending the period at 2.35% and high yield default rates at 2.26%, as reported by JPMorgan. Both figures still compare favorably against historical averages, which reside within the 3.0 – 3.5% range.

Strategic Review and Outlook: Anticipating continued demand for loans

For the semiannual period ended April 30, 2018, the Fund outperformed the Benchmark across all share classes. The allocation to bank loans was the largest contributor to absolute returns, as the asset class posted positive returns for the past six months. High yield detracted from returns while asset backed exposure contributed slightly. From a ratings perspective, B-rated and CCC-rated positions had the greatest contributions to returns, while BB-rated exposure had negligible impact. Sector-wise, oil & gas, consumer products and electronics were the greatest contributors.

Strong economic performance has been supportive of rate increases, and we believe this will continue. This, in turn, should, in our view, lead to positive institutional and prime fund demand for the loan asset class. Additionally, high yield spreads, which we believe have already somewhat priced in the rate increases, appear to have better relative value versus year-end 2017.

In addition, default rate expectations in the intermediate term are sanguine, as we believe rates will remain below long-term averages, especially outside of certain distressed sectors (like retail) that we believe are experiencing secular changes.

Lastly, while there has been some volatility in risk assets recently and geopolitical and inflation concerns have increased, underlying corporate fundamentals and economic data continue to remain solid.

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.

Credit Suisse Strategic Income Fund
Semiannual Investment Adviser's Report (continued)

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, 2018; these views and Fund holdings may have changed subsequent to these dates. Nothing in this document is a recommendation to purchase or sell securities.

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, 2018.

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.

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.

Credit Suisse Strategic Income Fund
Notes to Financial Statements
April 30, 2018 (unaudited)

Note 1. Organization

Credit Suisse Strategic Income Fund (the "Fund"), a series of the 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, which reflect the differences in the range of services provided to them. 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 Accounting Standards Codification ("ASC") Topic 946 — Financial Services — Investment Companies.

A) SECURITY VALUATION — 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

Note 2. Significant Accounting Policies (continued)

"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 of Trustees (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, the Fund values these securities as determined in accordance with procedures approved and established 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

39

Credit Suisse Strategic Income Fund
Notes to Financial Statements (continued)
April 30, 2018 (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, 2018 in valuing the Fund's assets and liabilities carried at fair value:

	Quantitative Disclosure About Significant Unobservable Inputs
Asset Class	Fair Value At 4/30/2018		Valuation Technique	Unobservable Input	Range (Weighted Average per share)
Corporate Bonds	$	1,882	Income Approach	Expected Remaining Distribution	N/A

	$	114,124	Market Approach/ Income Approach	Comparable Bond Price, Discounted Cash Flows	$	0.01 – $63,755.57	($989.45)

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 Asset Management, LLC, the Fund's investment adviser ("Credit Suisse" or the "Adviser") considers may include (i) the existence of any contractual restrictions on the disposition of securities; (ii) information obtained from the company, which may include an analysis of the company's financial statements, the company's products or intended markets or the company's technologies; (iii) the price of the same or similar security negotiated at arm's length in an issuer's completed subsequent round of financing; (iv) the price and extent of public trading in similar securities of the issuer or of comparable companies; or (v) a probability and time value adjusted analysis of contractual term. Where available and appropriate, multiple valuation methodologies are applied to confirm fair value. To the extent that valuation is based on models or inputs that are less observable or unobservable in the market, determining fair value requires more judgment. Because of the inherent uncertainty of valuation, those estimated values may be materially higher or lower than the values that would have been used had a ready market for the investments existed. Accordingly, the degree of judgment exercised by the Fund in determining fair value is greatest for investments categorized in Level 3. In some circumstances, the inputs used to measure fair value might be categorized within different levels of the fair value hierarchy. In those instances, the fair value measurement is categorized in its entirety in the fair value hierarchy based on the least observable input that is significant to the fair value measurement. Additionally, changes in the market environment and other events that 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, 2018, there were no transfers between Level 1 and Level 2, and $4,121,790 transferred from Level 2 to Level 3 due to

a lack of a pricing source supported by observable inputs and $6,681,043 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, 2018, 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, 2018 and the effect of these derivatives on the Statement of Operations for the six months ended April 30, 2018.

Primary Underlying Risk	Derivative Assets		Derivative Liabilities		Realized Gain (Loss)			Change in Unrealized Appreciation (Depreciation)

For the six months ended April 30, 2018, the Fund held an average monthly value on a net basis of $5,434,790 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, 2018:

^(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 are translated into U.S. dollar amounts at the current exchange rate at the end of the period. 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

43

Notes to Financial Statements (continued)

Note 2. Significant Accounting Policies (continued)

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 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) SHORT-TERM INVESTMENTS — The Fund, together with other funds/portfolios advised by Credit Suisse, pools available cash into a short-term variable rate time deposit issued by State Street Bank and Trust Company

44

Credit Suisse Strategic Income Fund
Notes to Financial Statements (continued)
April 30, 2018 (unaudited)

Note 2. Significant Accounting Policies (continued)

("SSB"), the Fund's custodian. The short-term time deposit issued by SSB is a variable rate account classified as a short-term investment.

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, 2018, 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 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

45

Credit Suisse Strategic Income Fund
Notes to Financial Statements (continued)
April 30, 2018 (unaudited)

Note 2. Significant Accounting Policies (continued)

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, 2018 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 Statement of Investments. There were no unfunded commitments as of April 30, 2018.

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

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, 2018 and during the six months ended April 30, 2018, there were no securities out on loan.

Note 2. Significant Accounting Policies (continued)

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.

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 October 2016, the U.S. Securities and Exchange Commission adopted new rules and amended existing rules (together, "final rules") intended to modernize the reporting and disclosure of information by registered investment companies. In part, the final rules amend Regulation S-X and require standardized, enhanced disclosure about derivatives in investment company financial statements, as well as other amendments. The compliance date for the amendments to Regulation S-X is August 1, 2017. The Fund has adopted the amendments to Regulation S-X and upon evaluation, has concluded that the amendments do not materially impact the financial statements. However, as required, additional or enhanced disclosure has been included.

N) SUBSEQUENT EVENTS — In preparing the financial statements as of April 30, 2018, management considered the impact of subsequent events for potential recognition or disclosure in these financial statements through the date of release of this report. No such events requiring recognition or disclosure were identified through the date of the release of this report.

Credit Suisse Asset Management Limited ("Credit Suisse U.K."), an affiliate of Credit Suisse, serves as sub-investment advisor to the Fund directly. Credit Suisse U.K.'s sub-investment advisor fees are paid by Credit Suisse.

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, 2018, co-administrative services fees earned by SSB (including out-of-pocket expenses) with respect to the Fund were $33,285.

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 C

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

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, 2018, the Fund paid Rule 12b-1 distribution fees of $48,036 for Class A shares and $188,041 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, 2018, the Fund paid $16,095, which is included within transfer agent fees in the Statement of Operations.

For the six months ended April 30, 2018, CSSU and its affiliates advised the Fund that they retained $15,865 from commissions earned on the sale of the Fund's Class A shares. There were no commissions earned on the sale of Class C shares.

The Fund from time to time purchases or sells loan investments in the secondary market through Credit Suisse or its affiliates acting in the capacity as broker-dealer. Credit Suisse or its affiliates may have acted in some type of agent capacity to the initial loan offering prior to such loan trading in the secondary market.

Note 4. Line of Credit

The Fund, 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 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, 2018 and during the six months ended April 30, 2018, the Fund had no loan borrowings outstanding under the Credit Facility.

Note 5. Purchases and Sales of Securities

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.

Board Approval of Investment Management Agreement (unaudited)

In approving the amended and restated investment management agreement and 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 meeting held on November 13 and 14, 2017, 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 considered that Credit Suisse entered into an expense limitation agreement ("Expense Limitation Agreement") limiting the Fund's total net expenses to 1.24%, 1.99% and 0.99% of the average daily net assets of Class A, Class C and Class I, respectively, until February 28, 2018.

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.

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 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. 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 Fund is different from other types of accounts offered by Credit Suisse and the services are different from those offered 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.

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 time, 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 considered the positive investment performance of the Fund relative to its stated objectives as well as the performance of the Fund relative to its peers.

Credit Suisse Profitability

The Board received and considered a profitability analysis of Credit Suisse based on the fees payable under the 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 profitability information for the other funds in the Credit Suisse family of 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 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 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.

•  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 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 advisers.

•  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 profitability based on fees payable under the 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 Management Agreement and Sub-Advisory Agreement. The Independent Trustees were advised by separate independent legal counsel throughout the process.
