Annual Investment Adviser's Report

November 24, 2017

Dear Shareholder:

We are pleased to present this Annual Report covering the activities of the Credit Suisse Floating Rate High Income Fund (the "Fund") for the 12-month period ended October 31, 2017.

Performance Summary
11/1/2016 – 10/31/2017

Fund & Benchmark	Performance
Class I1		5.75	%
Class A1,2		5.48	%
Class B1,2		4.69	%
Class C1,2		4.69	%
Credit Suisse Leveraged Loan Index3		5.25	%

Performance shown for the Fund's Class A, Class B and Class C Shares does not reflect sales charges, which are a maximum of 4.75%, 4.00% and 1.00%, respectively.²

Market Review: A positive period for senior loans

The twelve-month period ended October 31, 2017 was a positive one for the senior secured loan asset class, with the Credit Suisse Leveraged Loan Index (the "Benchmark"), the Fund's benchmark, returning 5.25% for the period. The discount margin for senior loans, using a three-year average life assumption, tightened 0.77% during the period to +417 basis points. Returns for the asset class have been largely driven by coupons.

Demand for leveraged loans has been robust as retail money flowed into loan funds, old Collateralized Loan Obligation ("CLO") structures reset, and new CLO's printed an average of almost $10 billion per month over the twelve-month period. Prime funds had net inflows of $30.7 billion versus a $15.7 billion outflow over the previous annual period (according to LCD — "Leveraged Commentary & Data"). Spread compression hasn't been isolated to loans, with CLO's pricing at tighter levels and existing vehicles being refinanced/reset at record pace. The period saw CLO issuance of $111.5 billion versus $67 billion in the previous period. Calendar year to date, more than $150 billion of existing CLO's have also been refinanced or reset (representing over 325 vehicles).

Over the period, borrowers have been enticed to tap the loan market, as a record $959 billion of institutional loans were issued during the period — 73% of which was used for the refinancing/repricing of existing debt. In the previous period, issuance was $407 billion, with nearly 60% used for refinancing/repricing, according to JPMorgan.

Fundamentals in the senior secured loan market have been strong outside of energy and retail. The par-weighted default rate for loans ended the period at 1.37%. In fact, according to JPMorgan, 26 companies have defaulted in 2017 — putting it on pace for the lowest annual default total since 2013. While we expect an increase in defaults in some troubled industries going forward, overall fundamentals and cheap capital structures should broadly minimize defaults.

From a quality point of view, CCC/split CCC posted the highest returns for the period at 12.22%. Distressed (CC, C, and default) loans followed closely, returning 10.82%. Split BBB and BB rated loans underperformed with respective returns of 3.25% and 4.07%.

Strategic Review and Outlook: Expecting demand to remain positive

For the annual period ended October 31, 2017, the Fund's Class I and A shares outperformed the Benchmark. The Fund's outperformance was largely driven by positive security selection in the oil & gas sector. In addition, security selection and an underweight position to the retail sector were positive contributors to relative performance. From an asset class perspective, the Fund's weightings in high yield and asset-backed energy also contributed to performance.

Demand for the bank loan asset class continues to be solid, with steady issuer fundamentals, rate hike expectations (albeit at a measured pace), healthy institutional demand and elevated CLO formation levels. Additionally, outside of sectors like retail, default rates are expected to remain below long-term averages in the intermediate term.

Fundamental economic performance has remained stable and although there have been periods when international concerns and the domestic political climate have led to some volatility, the cautious investor sentiment was short lived. Barring a sudden increase in geopolitical risks, we would expect demand to remain positive thanks to economic performance that appears to be supportive of continued rate increases, as well as the attractiveness of 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 October 31, 2017; 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 October 31, 2017.

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*		0.70	%		0.95	%		1.70	%		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 184/365 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
October 31, 2017

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. Effective February 29, 2012, Class B shares of the Fund are no longer being offered for sale. Existing shareholders may continue to purchase additional Class B shares of the Fund through the reinvestment of dividends and capital gain distributions paid by the Fund. Class B shares automatically convert to Class A shares after 8 years.

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

41

Credit Suisse Floating Rate High Income Fund
Notes to Financial Statements (continued)
October 31, 2017

Note 2. Significant Accounting Policies (continued)

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 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.

Notes to Financial Statements (continued)
October 31, 2017

Note 2. Significant Accounting Policies (continued)

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

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

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

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

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

The following is a summary of the inputs used as of October 31, 2017 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	$	—	$	2,782,123,032	$	224,726,885	$	3,006,849,917

*Other financial instruments include unrealized appreciation (depreciation) on forward foreign currency contracts.

The following is a reconciliation of investments as of October 31, 2017 for which significant unobservable inputs were used in determining value. All transfers, if any, are assumed to occur at the end of the reporting period.

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

44

Credit Suisse Floating Rate High Income Fund
Notes to Financial Statements (continued)
October 31, 2017

Note 2. Significant Accounting Policies (continued)

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 year ended October 31, 2017, there were no transfers between Level 1 and Level 2, but there was $58,560,852 transferred from Level 2 to Level 3 due to a lack of a pricing source supported by observable inputs and $111,556,243 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 year ended October 31, 2017, the Fund held an average monthly value on a net basis of $186,631,527 in forward foreign currency contracts.

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

The following table presents by counterparty the Fund's derivative assets, net of related collateral held by the Fund, at October 31, 2017:

Note 2. Significant Accounting Policies (continued)

C) FOREIGN CURRENCY TRANSACTIONS — The books and records of the Fund are maintained in U.S. dollars. Transactions denominated in foreign currencies are recorded at the current prevailing exchange rates. All assets and liabilities denominated in foreign currencies 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 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

47

Credit Suisse Floating Rate High Income Fund
Notes to Financial Statements (continued)
October 31, 2017

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.

F) FEDERAL INCOME 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 ("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

48

Credit Suisse Floating Rate High Income Fund
Notes to Financial Statements (continued)
October 31, 2017

Note 2. Significant Accounting Policies (continued)

forward exchange rate of the underlying currencies and unrealized gain/loss is recorded daily. On the settlement date of the forward currency contract, the Fund records a realized gain or loss equal to the difference between the value of the contract at the time it was opened and the value of the contract at the time it was closed. Certain risks may arise upon entering into forward currency contracts from the potential inability of counterparties to meet the terms of their contracts. The maximum counterparty credit risk to the Fund is measured by the unrealized gain on appreciated contracts. Additionally, when utilizing forward currency contracts to hedge, the Fund forgoes the opportunity to profit from favorable exchange rate movements during the term of the contract. The Fund's open forward currency contracts at October 31, 2017 are disclosed in the Schedule of Investments.

I) UNFUNDED LOAN COMMITMENTS — The Fund enters into certain agreements, all or a portion of which may be unfunded. The Fund is obligated to fund these loan commitments at the borrowers' discretion. Funded and unfunded portions of credit agreements are presented in the Schedule of Investments. As of October 31, 2017, unfunded commitments were as follows:

Borrower	Maturity	Rate		Unfunded Commitment
TricorBraun Holdings, Inc.	11/30/23		3.750	$	1,791,983

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

49

Credit Suisse Floating Rate High Income Fund
Notes to Financial Statements (continued)
October 31, 2017

Note 2. Significant Accounting Policies (continued)

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 October 31, 2017, the Fund had investment securities on loan with a fair value of $6,901,536. Collateral received for securities loaned and a related liability of $7,049,810 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 October 31, 2017, the value of the related collateral exceeded the value of the securities loaned.

The Fund's securities lending arrangement provides that the Fund and SSB will share the net income earned from securities lending activities. Securities lending income is accrued as earned. During the year ended October 31, 2017, total earnings from the Fund's investment in cash collateral received in connection with securities lending arrangements was $98,263, of which $20,036 was rebated to borrowers (brokers). The Fund retained $58,674 in income from the cash collateral investment, and SSB, as lending agent, was paid $19,553.

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

50

Credit Suisse Floating Rate High Income Fund
Notes to Financial Statements (continued)
October 31, 2017

Note 2. Significant Accounting Policies (continued)

and the Fund's net asset value.

L) RECENT ACCOUNTING PRONOUNCEMENTS — On August 26, 2016, Financial Accounting Standards Board ("FASB") issued Accounting Standards Update No. 2016-15, "Statement of Cash Flows (Topic 230), a consensus of the FASB's Emerging Issues Task Force" ("ASU 2016-15"). ASU 2016-15 is intended to reduce diversity in practice in how certain transactions are classified in the statement of cash flows. The issues addressed in ASU 2016-15 are: debt prepayment or debt extinguishment costs, settlement of zero-coupon debt instruments, contingent consideration payments made after a business combination, proceeds from the settlement of insurance claims, proceeds from the settlement of corporate-owned life insurance policies, including bank-owned life insurance policies, distributions received from equity method investments, beneficial interests in securitization transactions; and, separately identifiable cash flows and application of the predominance principle. ASU 2016-15 is effective for interim and annual reporting periods beginning after December 15, 2017. Management is currently evaluating the impact, if any, of applying this provision.

In November 2016, FASB issued Accounting Standards Update No. 2016-18, "Statement of Cash Flows (Topic 230), Restricted Cash, a consensus of the FASB's Emerging Issues Task Force" ("ASU 2016-18"). ASU 2016-18 requires that a statement of cash flows explain the change during the period in the total of cash, cash equivalents, and amounts generally described as restricted cash or restricted cash equivalents. Therefore, amounts generally described as restricted cash and restricted cash equivalents should be included with cash and cash equivalents when reconciling the beginning-of-period and end-of-period total amounts shown on the statement of cash flows. The amendments in ASU 2016-18 do not provide a definition of restricted cash or restricted cash equivalents. ASU 2016-18 is effective for interim and annual reporting periods beginning after December 15, 2017. Management is currently evaluating the impact, if any, of applying this provision.

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

51

Credit Suisse Floating Rate High Income Fund
Notes to Financial Statements (continued)
October 31, 2017

Note 2. Significant Accounting Policies (continued)

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 October 31, 2017, 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. Effective November 15, 2016, 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. Prior to November 15, 2016, the Fund paid Credit Suisse advisory fees at the annual rate of 0.70% of the Fund's average daily net assets less than or equal to $100 million and 0.50% of the Fund's average daily net assets greater than $100 million, and co-administration fees at an annual rate of 0.09% of the Fund's average daily net assets. On November 15, 2016, the Fund entered into an Investment Management Agreement with Credit Suisse which bundled the advisory and administration fees into a single fee. For the year ended October 31, 2017, investment advisory and administration fees earned and voluntarily waived by Credit Suisse were $19,324,122 and $2,404,609, 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 year ended October 31, 2017, co-administrative services fees earned by SSB (including out-of-pocket expenses) with respect to the Fund were $483,764.

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

52

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

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

daily net assets. For the year ended October 31, 2017, the Fund paid Rule 12b-1 distribution fees of $690,076 for Class A shares, $15,299 for Class B shares and $1,197,350 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 year ended October 31, 2017, the Fund paid $2,724,048, which is included within transfer agent fees in the Statement of Operations.

For the year ended October 31, 2017, CSSU and its affiliates advised the Fund that they retained $46,914 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 October 31, 2017 and during the year ended October 31, 2017, the Fund had no borrowings outstanding under the Credit Facility.

Note 6. Capital Share Transactions

The Fund is authorized to issue an unlimited number of full and fractional shares of beneficial interest, $.001 par value per share. The Fund offers Class I, Class A, and Class C shares. Class B shares are shown but not offered. Effective December 15, 2017, all issued and outstanding Class B shares will be converted into Class A shares based on the aggregate net assets attributable to the Class B shares, and respective Class A net asset value per share immediately prior to the conversion.

Note 7. Income Tax Information and Distributions to Shareholders (continued)

The tax basis components of distributable earnings differ from the amounts reflected in the Statement of Assets and Liabilities by temporary book/tax differences. These differences are primarily due to differing treatments of dividends payable, wash sales, forward contracts marked to market and income from defaulted bonds. At October 31, 2017, the components of distributable earnings on a tax basis were as follows:

Accumulated net realized loss	$	(15,563,446	)
Unrealized appreciation		17,381,923
	$	1,818,477

At October 31, 2017, the Fund had $2,871,951 of unlimited short-term capital loss carryforwards and $12,691,495 of unlimited long-term capital loss carryforwards available to offset possible future capital gains.

At October 31, 2017, the cost and net unrealized appreciation (depreciation) of investments and derivatives for income tax purposes were as follows:

Cost of Investments	$	3,755,050,189
Unrealized appreciation	$	58,546,403
Unrealized depreciation		(41,064,664	)
Net unrealized appreciation (depreciation)	$	17,481,739

To adjust for current period permanent book/tax differences which arose principally from differing book/tax treatment of foreign currency gain (loss) and defaulted bonds, paid-in capital was charged $73, distributions in excess of net investment income was charged $2,500,248 and accumulated net realized loss was credited $2,500,321. Net assets were not affected by this reclassification.

Note 8. 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.

The Board of Trustees and Shareholders
Credit Suisse Floating Rate High Income Fund:

We have audited the accompanying statement of assets and liabilities of Credit Suisse Floating Rate High Income Fund (the "Fund"), a series of the Credit Suisse Opportunity Funds, including the schedule of investments, as of October 31, 2017, and the related statement of operations for the year then ended, the statements of changes in net assets for each of the years in the two-year period then ended, and the financial highlights for each of the years in the three-year period then ended. These financial statements and financial highlights are the responsibility of the Fund's management. Our responsibility is to express an opinion on these financial statements and financial highlights based on our audits. The accompanying financial highlights for each of the years in the two-year period ended October 31, 2014, were audited by other independent registered public accountants whose report thereon dated December 29, 2014, expressed an unqualified opinion on those financial highlights.

We conducted our audits in accordance with the standards of the Public Company Accounting Oversight Board (United States). Those standards require that we plan and perform the audits to obtain reasonable assurance about whether the financial statements and financial highlights are free of material misstatement. An audit includes examining, on a test basis, evidence supporting the amounts and disclosures in the financial statements. Our procedures included confirmation of securities owned as of October 31, 2017, by correspondence with the custodian and broker or by other appropriate auditing procedures. An audit also includes assessing the accounting principles used and significant estimates made by management, as well as evaluating the overall financial statement presentation. We believe that our audits provide a reasonable basis for our opinion.

In our opinion, the financial statements and financial highlights referred to above present fairly, in all material respects, the financial position of Credit Suisse Floating Rate High Income Fund as of October 31, 2017, the results of its operations for the year then ended, the changes in its net assets for each of the years in the two-year period then ended, and the financial highlights for each of the years in the three-year period then ended in conformity with U.S. generally accepted accounting principles.

Credit Suisse Managed Futures Strategy Fund
Annual Investment Adviser's Report
October 31, 2017 (unaudited)

November 24, 2017

Dear Shareholder:

We are pleased to present this Annual Report covering the activities of the Credit Suisse Managed Futures Strategy Fund (the "Fund") for the 12-month period ended October 31, 2017.

Performance Summary
11/1/2016 – 10/31/2017

Fund & Benchmark	Performance
Class I1		-1.60	%
Class A1,2		-1.79	%
Class C1,2		-2.52	%
Credit Suisse Managed Futures Liquid Index3		-2.19	%

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 twelve-month period ended October 31, 2017 was a tough one for managed futures strategies, with the Credit Suisse Managed Futures Hedge Fund Index returning 0.15% and the Credit Suisse Managed Futures Liquid Index, the Fund's benchmark, returning -2.19%.

Over the past year, as a number of underlying markets experienced medium to long-term reversals, the entire managed futures industry tended to struggle.

Portfolio Review and Outlook: Relative outperformance in a tough climate

The managed futures strategy is generally designed to profit from both upward and downward trending markets across several asset classes including commodities, bonds, equities, and currencies. For the 12-month period ended October 31, 2017, the Fund outperformed its benchmark, with a return of -1.60% (I shares), as compared to -2.19% for the Credit Suisse Managed Futures Liquid Index. Equity positions contributed positively to Fund performance, while fixed income, commodities and currencies detracted from performance.

Equity positions were the largest contributor to Fund performance due to persistent long positions in underlying contracts that generated profits from the sustained equity market rally that began following the U.S. presidential election last November. Earnings improvements, a synchronized global growth cycle, and heightened consumer confidence combined to push markets higher.

1

Credit Suisse Managed Futures Strategy Fund
Annual Investment Adviser's Report (continued)
October 31, 2017 (unaudited)

Fixed income positions were the largest detractors from performance, as conflicting inflation measures, central bank policy, and geopolitical risks increased the market's vulnerability to reversals and made it impossible to sustain market trends.

Commodities were the second largest detractor from performance over the period. Although persistent long positions in industrial metals delivered profits, they were offset by losses in energy, precious metals (which fluctuated due to the same challenges as fixed income), and agriculture.

Currencies also detracted from Fund performance. Long U.S. dollar positions initially profited following the election, but legislative setbacks caused a retreat at the beginning of the year that resulted in subsequent losses.

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

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

The use of alternative assets and strategies entails substantial risks, including risk of loss of principal, commodity exposure risks, credit risk, currency risk, derivatives risk, equity exposure risk, exchange-traded notes risk, fixed income risk, foreign securities risk, forwards risk, futures contracts risk, interest rate risk, leveraging risk, market risk, 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 October 31, 2017; 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.

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 (6.93)%. Total return for the Fund's Class C shares for the reporting period, based on redemption value including CDSC of 1.00%, was (3.47)%.

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 October 31, 2017.

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 184/365 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 expenses 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 Managed Futures Strategy Fund
Notes to Consolidated Financial Statements
October 31, 2017

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 October 31, 2017, the Fund held $11,968,759 in the Subsidiary, representing 3.9% of the Fund's consolidated net assets. For the year ended October 31, 2017, the net realized loss on securities and other financial instruments held in the Subsidiary was $6,075,866.

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

Credit Suisse Managed Futures Strategy Fund
Notes to Consolidated Financial Statements (continued)
October 31, 2017

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 October 31, 2017 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	$	—	$	119,540,691	$	—	$	119,540,691

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

For the year ended October 31, 2017, 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 year ended October 31, 2017, the Fund's derivatives did not qualify for hedge accounting as they are held at fair value.

The notional amount of futures contracts and swap contracts open at October 31, 2017 is reflected in the Consolidated Schedule of Investments. For the year ended October 31, 2017, the Fund held average monthly notional values on a net basis of $437,745,292, $220,158,433 and $82,099,557 in long futures contracts, short futures contracts and swap contracts, respectively.

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

The following table presents by counterparty the Fund's derivative assets, net of related collateral held by the Fund, at October 31, 2017:

Note 2. Significant Accounting Policies (continued)

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 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

22

Credit Suisse Managed Futures Strategy Fund
Notes to Consolidated Financial Statements (continued)
October 31, 2017

Note 2. Significant Accounting Policies (continued)

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.

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

23

Credit Suisse Managed Futures Strategy Fund
Notes to Consolidated Financial Statements (continued)
October 31, 2017

Note 2. Significant Accounting Policies (continued)

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 October 31, 2017, the amount of restricted cash held at brokers related to open futures contracts was $20,972,511.

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

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

24

Credit Suisse Managed Futures Strategy Fund
Notes to Consolidated Financial Statements (continued)
October 31, 2017

Note 2. Significant Accounting Policies (continued)

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 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 October 31, 2017, the amount of restricted cash held at brokers related to open swap contracts was $4,800,000.

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

25

Credit Suisse Managed Futures Strategy Fund
Notes to Consolidated Financial Statements (continued)
October 31, 2017

Note 2. Significant Accounting Policies (continued)

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 October 31, 2017 and during the year ended October 31, 2017, 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 approximates their carrying value as recorded in the Fund's Consolidated Statement of Assets and Liabilities.

K) RECENT ACCOUNTING PRONOUNCEMENTS — On August 26, 2016, Financial Accounting Standards Board ("FASB") issued Accounting Standards Update No. 2016-15, "Statement of Cash Flows (Topic 230), a consensus of the FASB's Emerging Issues Task Force" ("ASU 2016-15"). ASU 2016-15 is intended to reduce diversity in practice in how certain transactions are classified in the statement of cash flows. The issues addressed in ASU 2016-15 are: debt prepayment or debt extinguishment costs, settlement of zero-coupon debt instruments, contingent consideration payments made after a business combination, proceeds from the settlement of insurance claims, proceeds from the settlement of corporate-owned life insurance policies, including bank-owned life insurance policies, distributions received from equity method investments, beneficial interests in securitization transactions; and, separately identifiable cash flows and application of the predominance principle. ASU 2016-15 is effective for interim and annual reporting periods beginning after December 15, 2017. Management is currently evaluating the impact, if any, of applying this provision.

26

Credit Suisse Managed Futures Strategy Fund
Notes to Consolidated Financial Statements (continued)
October 31, 2017

Note 2. Significant Accounting Policies (continued)

In November 2016, FASB issued Accounting Standards Update No. 2016-18, "Statement of Cash Flows (Topic 230), Restricted Cash, a consensus of the FASB's Emerging Issues Task Force" ("ASU 2016-18"). ASU 2016-18 requires that a statement of cash flows explain the change during the period in the total of cash, cash equivalents, and amounts generally described as restricted cash or restricted cash equivalents. Therefore, amounts generally described as restricted cash and restricted cash equivalents should be included with cash and cash equivalents when reconciling the beginning-of-period and end-of-period total amounts shown on the statement of cash flows. The amendments in ASU 2016-18 do not provide a definition of restricted cash or restricted cash equivalents. ASU 2016-18 is effective for interim and annual reporting periods beginning after December 15, 2017. Management is currently evaluating the impact, if any, of applying this provision.

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 October 31, 2017, 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. Effective November 15, 2016, 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. Prior to November 15, 2016, the Fund paid Credit Suisse advisory fees at the annual rate of 0.95% of the Fund's average daily net assets and co-administration fees at an annual rate of 0.09% of the Fund's average daily net assets.

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

Agreement with Credit Suisse which bundled the advisory and administration fees into a single fee. For the year ended October 31, 2017, investment advisory and administration fees earned and fees waived/expenses reimbursed by Credit Suisse were $2,336,463 and $204,020, 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.

The amounts waived and reimbursed by Credit Suisse, which are available for potential future recoupment by Credit Suisse, and the expiration schedule at October 31, 2017 are as follows:

	Fee waivers/ expense reimbursements subject to recoupment*		Expires October 31, 2018		Expires October 31, 2019		Expires October 31, 2020
Class I	$	147,730	$	60,735	$	10,796	$	76,199
Class A		49,773		13,830		3,236		32,707
Class C		4,174		2,053		356		1,765
Totals	$	201,677	$	76,618	$	14,388	$	110,671

*  Subsidiary expenses are not eligible for recoupment.

For its co-administrative services, SSB receives a fee, exclusive of out-of-pocket expenses, calculated in total for all the Credit Suisse funds/portfolios co-administered by SSB and allocated based upon the relative average net assets of each fund/portfolio, subject to an annual minimum fee. For the year ended October 31, 2017, co-administrative services fees earned by SSB (including out-of-pocket expenses) with respect to the Fund were $30,409.

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

28

Credit Suisse Managed Futures Strategy Fund
Notes to Consolidated Financial Statements (continued)
October 31, 2017

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

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 year ended October 31, 2017, the Fund paid Rule 12b-1 distribution fees of $165,358 for Class A shares and $36,118 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 year ended October 31, 2017, the Fund paid $159,957, which is included within transfer agent fees in the Consolidated Statement of Operations.

For the year ended October 31, 2017, CSSU and its affiliates advised the Fund that they retained $371 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.

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 October 31, 2017 and during the year ended October 31, 2017, the Fund had no borrowings outstanding under the Credit Facility.

Note 5. Purchases and Sales of Securities

For the year ended October 31, 2017, purchases and sales of investment securities (excluding short-term investments) and U.S. Government and Agency Obligations were as follows:

	Number of Shareholders		Approximate Percentage of Outstanding Shares
Class I		3		77	%
Class A		1		22	%
Class C		2		27	%

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. Income Tax Information and Distributions to Shareholders

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

The tax character of distributions paid during the fiscal years ended October 31, 2017 and 2016, respectively, was as follows:

Ordinary Income				Long-Term Capital Gain
2017		2016		2017		2016
$	2,100,180	$	6,475,503	$	2,547,400	$	2,163,304

The tax basis components of distributable earnings differ from the amounts reflected in the Consolidated Statement of Assets and Liabilities by temporary book/tax differences. These differences are primarily due to differing treatments of futures contracts marked to market and offering expenses. At October 31, 2017, the components of distributable earnings on a tax basis were as follows:

Unrealized Appreciation $ 4,492,352

At October 31, 2017, the cost and net unrealized appreciation (depreciation) of investments and derivatives for income tax purposes were as follows:

Cost of Investments	$	272,854,428
Unrealized appreciation	$	10,010,506
Unrealized depreciation		(5,447,439	)
Net unrealized appreciation (depreciation)	$	4,563,067

To adjust for current period permanent book/tax differences which arose principally from differing book/tax treatment of foreign currency gain (loss) and Subsidiary accumulated income (loss), paid-in capital was charged $7,534,759, accumulated net realized gain was credited $5,135,326 and distributions in excess of net investment income was credited $2,399,433. Net assets were not affected by these reclassifications.

Note 8. 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 Managed Futures Strategy Fund
Report of Independent Registered Public Accounting Firm

The Board of Trustees and Shareholders
Credit Suisse Managed Futures Strategy Fund:

We have audited the accompanying consolidated statement of assets and liabilities of Credit Suisse Managed Futures Strategy Fund (the "Fund"), a series of the Credit Suisse Opportunity Funds, including the consolidated schedule of investments, as of October 31, 2017, and the related consolidated statement of operations for the year then ended, and the consolidated statements of changes in net assets for each of the years in the two-year period then ended, and the financial highlights for each of the years in the three-year period then ended. These consolidated financial statements and consolidated financial highlights are the responsibility of the Fund's management. Our responsibility is to express an opinion on these consolidated financial statements and consolidated financial highlights based on our audits. The accompanying consolidated financial highlights for the years in the two-year period ended October 31, 2014 were audited by other independent registered public accountants whose report thereon dated December 29, 2014, expressed an unqualified opinion on those consolidated financial highlights.

We conducted our audits in accordance with the standards of the Public Company Accounting Oversight Board (United States). Those standards require that we plan and perform the audits to obtain reasonable assurance about whether the consolidated financial statements and consolidated financial highlights are free of material misstatement. An audit includes examining, on a test basis, evidence supporting the amounts and disclosures in the consolidated financial statements. Our procedures included confirmation of securities owned as of October 31, 2017, by correspondence with the custodian and broker or by other appropriate auditing procedures. An audit also includes assessing the accounting principles used and significant estimates made by management, as well as evaluating the overall consolidated financial statement presentation. We believe that our audits provide a reasonable basis for our opinion.

In our opinion, the consolidated financial statements and consolidated financial highlights referred to above present fairly, in all material respects, the financial position of Credit Suisse Managed Futures Strategy Fund as of October 31, 2017, the results of its operations for the year then ended, the changes in its net assets for each of the years in the two-year period then ended, and the financial highlights for each of the years in the three-year period then ended in conformity with U.S. generally accepted accounting principles.

Annual Investment Adviser's Report
October 31, 2017 (unaudited)

November 24, 2017

Dear Shareholder:

We are pleased to present this Annual Report covering the activities of the Credit Suisse Multialternative Strategy Fund (the "Fund") for the 12-month period ended October 31, 2017.

Performance Summary
11/1/2016 – 10/31/2017

Fund & Benchmark	Performance
Class I1		3.68	%
Class A1,2		3.45	%
Class C1,2		2.61	%
Credit Suisse Hedge Fund Index3		7.46	%
Credit Suisse Liquid Alternative Beta Index4		4.83	%

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 strong period for alternative strategies

The annual period ended October 31, 2017 was a strong one for hedge funds, with the Credit Suisse Hedge Fund Index, the Fund's primary benchmark, returning 7.46%.

Within the hedge fund universe, long/short equity funds yielded the strongest performance — benefitting from the emerging synchronized global growth cycle that raised earnings expectations, resulting in a sustained equity market rally.

Despite suffering from a momentary rise in the U.S. dollar following the November 2016 U.S. presidential election, emerging market currency and credit related strategies ultimately benefitted from significant tailwinds due to the dollar's continual decline throughout 2017. Managed futures and macro funds were the worst performers over the period due to sharp reversals in markets in which persistent, exploitable trends were scarce. As a result of being on the wrong side of the larger reversals across markets, performance in these funds was mixed. Elements of the "Trump Trade" that performed well following the election incurred subsequent losses in early January — this was particularly pronounced in currency and rates markets.

Strategic Review: Performance across asset classes

The Fund follows a multi-strategy methodology and benefitted from exposure across different markets and asset classes. For the 12-month period ended

Credit Suisse Multialternative Strategy Fund
Annual Investment Adviser's Report (continued)
October 31, 2017 (unaudited)

October 31, 2017, however, the Fund underperformed its primary and secondary benchmarks, with a return of 3.68% (I shares) as compared to 7.46% for the Credit Suisse Hedge Fund Index and 4.83% for the Credit Suisse Liquid Alternative Beta Index.

From an asset class perspective, equity performance during the strong bull market was the biggest contributor to the Fund's return, followed by fixed income and volatility. Commodity and foreign exchange strategies both modestly detracted from Fund performance.

Within equities, value was the most profitable investment style due to broad long market exposures that took advantage of the persistent rally, complemented by select long and short positions in certain sectors. Tilts toward technology and small cap equities in developed markets were particularly profitable.

Fixed income value was the second largest contributing strategy, aided primarily by long high yield credit exposure that benefitted from tightening spreads (which approached multi-year lows).

Volatility liquidity/insurance strategies yielded the third largest gains over the period, as the equity market rally supported an increasingly low volatility environment favorable for these strategies. Despite decade-low volatility, a diverse set of strategies took advantage of implied-realized spreads and structural inefficiencies in volatility markets.

In commodities, losses were incurred due to value strategies based on the seasonality of certain markets and the relative positioning of market participants.

Multi-asset trend following was negative for the period, on continued reversal or sideways movements in fixed income, currency and commodity markets. Equity trend following posted positive performance based on broad-based upward trends across equity markets globally.

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.

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 October 31, 2017.

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 184/365 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 October 31, 2017, the Fund held $6,404,958 in the Subsidiary, representing 6.2% of the Fund's consolidated net assets. For the year ended October 31, 2017, the net realized loss on securities and other financial instruments held in the Subsidiary was $1,212,064.

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. 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

32

Credit Suisse Multialternative Strategy Fund
Notes to Consolidated Financial Statements (continued)
October 31, 2017

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 October 31, 2017, the amount of Level 3 securities that were measured at fair value amounted to less than 0.01% of net assets. For the year ended October 31, 2017, 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 year ended October 31, 2017, the Fund's derivatives did not qualify for hedge accounting as they are held at fair value.

For the year ended October 31, 2017, the Fund held average monthly value on a net basis of $21,455,557 in forward foreign currency contracts and average monthly notional values on a net basis of $51,372,149, $35,626,715 and $106,311,567 in long futures contracts, short futures contracts and swap contracts, respectively. For the year ended October 31, 2017, the Fund received average monthly premiums of $237,044 from written options contracts.

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

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

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

C) FOREIGN CURRENCY TRANSACTIONS — The books and records of the Fund are maintained in U.S. dollars. Transactions denominated in foreign currencies are recorded at the current prevailing exchange rates. All assets and liabilities denominated in foreign currencies 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

36

Credit Suisse Multialternative Strategy Fund
Notes to Consolidated Financial Statements (continued)
October 31, 2017

Note 2. Significant Accounting Policies (continued)

liabilities denominated in foreign currencies arises from changes in the fair values of assets and liabilities, other than investments, at the end of the period, resulting from changes in exchange rates. The Fund does not isolate that portion of the results of operations resulting from fluctuations in foreign exchange rates on investments from the fluctuations arising from changes in market prices of investments held. Such fluctuations are included with net realized and unrealized gain or loss from investments in the Consolidated Statement of Operations.

D) SECURITY TRANSACTIONS AND INVESTMENT INCOME/EXPENSE — Security transactions are accounted for on a trade date basis. Interest income/expense is recorded on the accrual basis. The Fund amortizes premiums and accretes discounts using the effective interest method. Dividend income/expense is recorded on the ex-dividend date. Foreign dividend income is recorded on the ex-dividend date or as soon as practicable after the Fund determines the existence of a dividend declaration after exercising reasonable due diligence. Certain expenses are class-specific expenses, vary by class and are charged only to that class. Income, expenses (excluding class-specific expenses) and realized/unrealized gains/losses are allocated proportionately to each class of shares based upon the relative net asset value of the outstanding shares of that class. The cost of investments sold is determined by use of the specific identification method for both financial reporting and income tax purposes. To the extent any issuer defaults or a credit event occurs that impacts the issuer, the Fund may halt any additional interest income accruals and consider the realizability of interest accrued up to the date of default or credit event.

E) DIVIDENDS AND DISTRIBUTIONS TO SHAREHOLDERS — Dividends from net investment income, if any, are declared and paid quarterly. Distributions of net realized capital gains, if any, are declared and paid at least annually. However, to the extent that a net realized capital gain can be reduced by a capital loss carryforward, such gain will not be distributed. Dividends and distributions to shareholders of the Fund are recorded on the ex-dividend date and are determined in accordance with federal income tax regulations, which may differ from GAAP.

F) FEDERAL AND OTHER TAXES — No provision is made for federal taxes as it is the Fund's intention to continue to qualify as a regulated investment company ("RIC") under the Internal Revenue Code of 1986, as amended (the "Code"), and to make the requisite distributions to its shareholders, which will be sufficient to relieve it from federal income and excise taxes.

37

Credit Suisse Multialternative Strategy Fund
Notes to Consolidated Financial Statements (continued)
October 31, 2017

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

38

Credit Suisse Multialternative Strategy Fund
Notes to Consolidated Financial Statements (continued)
October 31, 2017

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 October 31, 2017, 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

39

Credit Suisse Multialternative Strategy Fund
Notes to Consolidated Financial Statements (continued)
October 31, 2017

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 October 31, 2017, the amount of restricted cash held at brokers related to open futures contracts was $1,230,484.

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 October 31, 2017 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

40

Credit Suisse Multialternative Strategy Fund
Notes to Consolidated Financial Statements (continued)
October 31, 2017

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

41

Credit Suisse Multialternative Strategy Fund
Notes to Consolidated Financial Statements (continued)
October 31, 2017

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 October 31, 2017, the amounts of restricted cash held at brokers related to open swap contracts and centrally cleared swaps for the Fund were $10,698,248 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

42

October 31, 2017

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 October 31, 2017, the amount of restricted cash held at brokers related to option contracts was $1,181,760.

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 October 31, 2017, the Fund had investment securities on loan with a fair value of $35,904. Collateral received for securities loaned and a related liability of $37,455 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 October 31, 2017, the value of the related collateral exceeded the value of the securities loaned.

During the year ended October 31, 2017, total earnings from the Fund's investment in cash collateral received in connection with securities lending

43

Credit Suisse Multialternative Strategy Fund
Notes to Consolidated Financial Statements (continued)
October 31, 2017

Note 2. Significant Accounting Policies (continued)

arrangements was $23,763, of which $1,990 was rebated to borrowers (brokers). The Fund retained $16,329 in income from the cash collateral investment, and SSB, as lending agent, was paid $5,444. Securities lending income is accrued as earned.

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

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

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

P) RECENT ACCOUNTING PRONOUNCEMENTS — On August 26, 2016, Financial Accounting Standards Board ("FASB") issued Accounting Standards Update No. 2016-15, "Statement of Cash Flows (Topic 230), a consensus of the FASB's Emerging Issues Task Force" ("ASU 2016-15"). ASU 2016-15 is intended to reduce diversity in practice in how certain transactions are classified in the statement of cash flows. The issues addressed in ASU 2016-15 are: debt prepayment or debt extinguishment costs, settlement of zero-coupon debt

44

Credit Suisse Multialternative Strategy Fund
Notes to Consolidated Financial Statements (continued)
October 31, 2017

Note 2. Significant Accounting Policies (continued)

instruments, contingent consideration payments made after a business combination, proceeds from the settlement of insurance claims, proceeds from the settlement of corporate-owned life insurance policies, including bank-owned life insurance policies, distributions received from equity method investments, beneficial interests in securitization transactions; and, separately identifiable cash flows and application of the predominance principle. ASU 2016-15 is effective for interim and annual reporting periods beginning after December 15, 2017. Management is currently evaluating the impact, if any, of applying this provision.

In November 2016, FASB issued Accounting Standards Update No. 2016-18, "Statement of Cash Flows (Topic 230), Restricted Cash, a consensus of the FASB's Emerging Issues Task Force" ("ASU 2016-18"). ASU 2016-18 requires that a statement of cash flows explain the change during the period in the total of cash, cash equivalents, and amounts generally described as restricted cash or restricted cash equivalents. Therefore, amounts generally described as restricted cash and restricted cash equivalents should be included with cash and cash equivalents when reconciling the beginning-of-period and end-of-period total amounts shown on the statement of cash flows. The amendments in ASU 2016-18 do not provide a definition of restricted cash or restricted cash equivalents. ASU 2016-18 is effective for interim and annual reporting periods beginning after December 15, 2017. Management is currently evaluating the impact, if any, of applying this provision.

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 October 31, 2017, 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. Effective November 15, 2016, 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. Prior to November 15, 2016, the Fund paid Credit Suisse advisory fees at the annual rate of 0.95% of the Fund's average daily net assets and co-administration fees at an annual rate of 0.09% of the Fund's average daily net assets. On November 15, 2016, the Fund entered into an Investment Management Agreement with Credit Suisse which bundled the advisory and administration fees into a single fee. For the year ended October 31, 2017, investment advisory and administration fees earned and fees waived/expenses reimbursed by Credit Suisse were $1,211,312 and $784,338, 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.

	Fee waivers/expense reimbursements subject to recoupment*		Expires October 31, 2018		Expires October 31, 2019		Expires October 31, 2020
Class I	$	1,584,567	$	276,384	$	606,964	$	701,219

Totals	$	1,636,173	$	311,470	$	614,758	$	709,945

*  Subsidiary expenses are not eligible for recoupment.

For its co-administrative services, SSB receives a fee, exclusive of out-of-pocket expenses, calculated in total for all the Credit Suisse funds/portfolios co-administered by SSB and allocated based upon the relative average net assets of each fund/portfolio, subject to an annual minimum fee. For the year ended October 31, 2017, co-administrative services fees earned by SSB (including out-of-pocket expenses) with respect to the Fund were $28,359.

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

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 year ended October 31, 2017, the Fund paid Rule 12b-1 distribution fees of $3,427 for Class A shares and $586 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 year ended October 31, 2017, the Fund paid $67,801, which is included within transfer agent fees in the Consolidated Statement of Operations.

For the year ended October 31, 2017, CSSU and its affiliates advised the Fund that they retained $449 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.

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 October 31, 2017 and during the year ended October 31, 2017, the Fund had no borrowings outstanding under the Credit Facility.

Note 6. Capital Share Transactions (continued)

On October 31, 2017, 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		4		97	%
Class A		3		60	%
Class C		1		100	%

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. Income Tax Information and Distributions to Shareholders

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

The tax character of distributions paid by the Fund during the fiscal years ended October 31, 2017 and 2016, respectively, was as follows:

Ordinary Income				Long-Term Capital Gain
2017		2016		2017		2016
$	1,562,939	$	170,434	$	915,803	$	72,642

The tax basis components of distributable earnings differ from the amounts reflected in the Consolidated Statement of Assets and Liabilities by temporary book/tax differences. These differences are primarily due to differing treatments of wash sales, marked to market of forward contracts, futures contracts, options contracts and deferred organizational expenses. At October 31, 2017, the components of distributable earnings on a tax basis were as follows:

Undistributed net investment income	$	4,590,172
Accumulated net realized gain		159,779
Unrealized appreciation		206,235
	$	4,956,186

49

Credit Suisse Multialternative Strategy Fund

October 31, 2017

Note 7. Income Tax Information and Distributions to Shareholders (continued)

At October 31, 2017, the cost and net unrealized appreciation (depreciation) of investments, securities sold short and derivatives for income tax purposes were as follows:

Cost of Investments	$	88,354,370
Unrealized appreciation	$	2,957,360
Unrealized depreciation		(2,737,449	)
Net unrealized appreciation (depreciation)	$	219,911

To adjust for current period permanent book/tax differences which arose principally from differing book/tax treatment of foreign currency gain (loss), ordinary loss netting to reduce short-term capital gains, swap gain (loss) and distribution re-designations, paid-in capital was charged $1,208,968, accumulated net realized gain was credited $330,250 and distributions in excess of net investment income was credited $878,718. Net assets were not affected by these reclassifications.

Note 8. 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
Report of Independent Registered Public Accounting Firm

The Board of Trustees and Shareholders
Credit Suisse Multialternative Strategy Fund:

We have audited the accompanying consolidated statement of assets and liabilities of Credit Suisse Multialternative Strategy Fund (the "Fund"), a series of the Credit Suisse Opportunity Funds, including the consolidated schedule of investments, as of October 31, 2017, and the related consolidated statement of operations for the year then ended, the consolidated statements of changes in net assets for each of the years in the two-year period then ended, and the consolidated financial highlights for each of the years in the three-year period then ended. These consolidated financial statements and consolidated financial highlights are the responsibility of the Fund's management. Our responsibility is to express an opinion on these consolidated financial statements and consolidated financial highlights based on our audits. The accompanying consolidated financial highlights for each of the years in the two-year period ended October 31, 2014, were audited by other independent registered public accountants whose report thereon dated December 29, 2014, expressed an unqualified opinion on those consolidated financial highlights.

We conducted our audits in accordance with the standards of the Public Company Accounting Oversight Board (United States). Those standards require that we plan and perform the audits to obtain reasonable assurance about whether the consolidated financial statements and consolidated financial highlights are free of material misstatement. An audit includes examining, on a test basis, evidence supporting the amounts and disclosures in the consolidated financial statements. Our procedures included confirmation of securities owned as of October 31, 2017, by correspondence with the custodian and broker or by other appropriate auditing procedures. An audit also includes assessing the accounting principles used and significant estimates made by management, as well as evaluating the overall consolidated financial statement presentation. We believe that our audits provide a reasonable basis for our opinion.

In our opinion, the consolidated financial statements and consolidated financial highlights referred to above present fairly, in all material respects, the financial position of Credit Suisse Multialternative Strategy Fund as of October 31, 2017, the results of its operations for the year then ended, the changes in its net assets for each of years in the two-year period then ended, and the financial highlights for each of the years in the three-year period then ended, in conformity with U.S. generally accepted accounting principles.

Annual Investment Adviser's Report
October 31, 2017 (unaudited)

November 24, 2017

Dear Shareholder:

We are pleased to present this Annual Report covering the activities of the Credit Suisse Strategic Income Fund (the "Fund") for the 12-month period ended October 31, 2017.

Performance Summary
11/1/2016 – 10/31/2017

Fund & Benchmark	Performance
Class I1		11.11	%
Class A1,2		10.71	%
Class C1,2		9.88	%
ICE BofAML 3-Month US Treasury Bill Index3		0.72	%

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

The annual period ended October 31, 2017 was a positive one for below investment grade credit asset classes, with the Credit Suisse Leveraged Loan Index and the ICE BofAML US High Yield Constrained Index returning 5.25% and 9.14%, respectively. In comparison, the ICE BofAML 3-Month US Treasury Bill Index (the "Benchmark"), the Fund's benchmark, returned 0.72% for the same time period.

The high yield asset class continued to produce positive returns in 2017 following a rally that began in 2016. Factors that contributed to positive sentiment included strength in global equity markets, higher oil prices, and enthusiasm surrounding U.S. tax reform. For the loan asset class, coupon clipping has driven much of the positive return and over 5% of the Credit Suisse Leveraged Loan Index's return can be attributed to interest return.

Demand for leveraged loans has been robust. Retail money flowed into loan funds, old Collateralized Loan Obligation ("CLO") structures reset, and new CLO's printed an average of almost $10 billion per month over the twelve-month period. Prime funds had net inflows of $30.7 billion versus a $15.7 billion outflow over the previous period (according to LCD —"Leveraged Commentary & Data"). The period saw CLO issuance of $111.5 billion versus $67 billion in the previous annual period. In contrast, high yield mutual fund flows have been

1

Annual Investment Adviser's Report (continued)
October 31, 2017 (unaudited)

negative, with outflows of $9.8 billion year to date, as compared to $7.2 billion of inflows for the same period last year.

Fundamentals in the high yield and senior secured loan market have been stable outside of some notable sectors such as retail. Within high yield, default activity, as measured by JP Morgan, ended the period at 1.18% — down from the same twelve-month period last year and year-end 2016. The par-weighted default rate for loans ended the period at 1.37%. While it is expected that the market may experience an increase in defaults for some troubled industries going forward, overall fundamentals and cheap capital structures should broadly minimize defaults. Looking forward, JPMorgan is keeping its 2018 default rate forecast at 2.0% — which remains below long-term averages.

Strategic Review and Outlook: Expecting defaults to remain low

For the 12-month period ended October 31, 2017, the Fund outperformed the Benchmark. The Fund's outperformance can be attributed to positive performance from multiple asset classes. Positive returns in mining, steel, iron and non-precious metals, electronics and conglomerate service within the bank loan and high yield asset classes provided the most significant contributions to performance. CLOs also contributed positively to returns, as did all ratings classes.

The ongoing low rate environment has continued to be supportive of corporate balance sheets, with solid earnings and stable fundamentals supporting credit markets. Additionally, the United States economy continues to experience stable growth, while the labor market continues to show strength.

Economic performance does appear to be supportive of continued rate increases, although we expect the pace to be measured in the absence of a more material inflation upside surprise. Consequently, we currently maintain a shorter duration in the high yield asset class and are positively inclined toward the floating rate nature of the loan asset class.

Finally, we expect default rates for both high yield and loans to remain below long-term averages over the intermediate term — especially outside of certain sectors.

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

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

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

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

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

The views of the Fund's management are as of the date of this letter and the Fund holdings described in this document are as of October 31, 2017; these views and Fund holdings may have changed subsequent to these dates. Nothing in this document is a recommendation to purchase or sell securities.

Credit Suisse Strategic Income Fund¹ Class I Shares,
Class A Shares^2, Class C Shares² and
ICE BofAML 3-Month US Treasury Bill Index³
from Inception (9/28/12).

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 0.99% of the Fund's average daily net assets for Class I shares, 1.24% of the Fund's average daily net assets for Class A shares and 1.99% of the Fund's average daily net assets for Class C shares through at least February 28, 2018. This limit excludes certain expenses, as set forth in the Fund's Prospectus.

²  Total return for the Fund's Class A shares for the reporting period, based on offering price (including maximum sales charge of 4.75%), was 5.41%. Total return for the Fund's Class C shares for the reporting period, based on redemption value (including maximum CDSC of 1.00%), was 8.88%.

³  Using only liquid securities, the ICE BofAML 3-Month US Treasury Bill Index seeks to replicate the return of the overall hedge fund industry, as represented by the Dow Jones Credit Suisse Hedge Fund Index. The index does not have transaction costs and investors may not invest directly in the index. The index was formerly known as The BofA Merrill Lynch 3-Month US Treasury Bill 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 October 31, 2017.

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 184/365 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 expenses 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.

Notes to Financial Statements
October 31, 2017

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 "round lot" size, but some

35

Credit Suisse Strategic Income Fund
Notes to Financial Statements (continued)
October 31, 2017

Note 2. Significant Accounting Policies (continued)

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.)

36

Credit Suisse Strategic Income Fund
Notes to Financial Statements (continued)
October 31, 2017

Note 2. Significant Accounting Policies (continued)

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

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

The following is a summary of the inputs used as of October 31, 2017 in valuing the Fund's assets and liabilities carried at fair value:

Each fair value determination is based on a consideration of relevant factors, including both observable and unobservable inputs. Observable and unobservable inputs that Credit Suisse 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.

Note 2. Significant Accounting Policies (continued)

For the year ended October 31, 2017, there were no transfers between Level 1 and Level 2, but there was $2,013,711 transferred from Level 2 to Level 3 due to a lack of a pricing source supported by observable inputs and $1,793,996 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 year ended October 31, 2017, the Fund's derivatives did not qualify for hedge accounting as they are held at fair value.

Fair Values of Derivative Instruments as of October 31, 2017

	Asset Derivatives			Liability Derivatives
	Balance Sheet Location	Fair Value		Balance Sheet Location	Fair Value
Currency Contracts	Unrealized appreciation on forward foreign currency contracts	$	48,822	Unrealized depreciation on forward foreign currency contracts	$	15,453

Currency Contracts	Net realized loss from forward foreign currency contracts	$	(168,907	)	Net change in unrealized appreciation (depreciation) from forward foreign currency contracts	$	10,651

For the year ended October 31, 2017, the Fund held an average monthly value on a net basis of $4,838,796 in forward foreign currency contracts.

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

Termination events applicable to the Fund may occur upon a decline in the Fund's net assets below a specified threshold over a certain period of time.

The following table presents by counterparty the Fund's derivative assets, net of related collateral held by the Fund, at October 31, 2017:

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

The following table presents by counterparty the Fund's derivative liabilities, net of related collateral pledged by the Fund, at October 31, 2017:

Morgan Stanley	$	15,453	$	(15,453	)	$	—	$	—	$	—

^(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

40

Credit Suisse Strategic Income Fund
Notes to Financial Statements (continued)
October 31, 2017

Note 2. Significant Accounting Policies (continued)

income/expense is recorded on the accrual basis. The Fund amortizes premiums and accretes discounts using the effective interest method. Dividend income/expense is recorded on the ex-dividend date. Certain expenses are class-specific expenses, vary by class and are charged only to that class. Income, expenses (excluding class-specific expenses) and realized/unrealized gains/losses are allocated proportionately to each class of shares based upon the relative net asset value of the outstanding shares of that class. The cost of investments sold is determined by use of the specific identification method for both financial reporting and income tax purposes. To the extent any issuer defaults or a credit event occurs that impacts the issuer, the Fund may halt any additional interest income accruals and consider the realizability of interest accrued up to the date of default or credit event.

E) DIVIDENDS AND DISTRIBUTIONS TO SHAREHOLDERS — Dividends from net investment income, if any, are declared daily and paid monthly. Distributions of net realized capital gains, if any, are declared and paid at least annually. However, to the extent that a net realized capital gain can be reduced by a capital loss carryforward, such gain will not be distributed. Dividends and distributions to shareholders of the Fund are recorded on the ex-dividend date and are determined in accordance with federal income tax regulations, which may differ from GAAP.

F) FEDERAL AND OTHER TAXES — No provision is made for federal taxes as it is the Fund's intention to continue to qualify as a regulated investment company ("RIC") under the Internal Revenue Code of 1986, as amended (the "Code"), and to make the requisite distributions to its shareholders, which will be sufficient to relieve it from federal income and excise taxes.

In order to qualify as a RIC under the Code, the Fund must meet certain requirements regarding the source of its income, the diversification of its assets and the distribution of its income. One of these requirements is that the Fund derive at least 90% of its gross income for each taxable year from dividends, interest, payments with respect to certain securities loans, gains from the sale or other disposition of stock, securities or foreign currencies, other income derived with respect to its business of investing in such stock, securities or currencies or net income derived from interests in certain publicly-traded 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

41

Credit Suisse Strategic Income Fund
Notes to Financial Statements (continued)
October 31, 2017

Note 2. Significant Accounting Policies (continued)

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) 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 October 31, 2017, 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

42

Credit Suisse Strategic Income Fund
Notes to Financial Statements (continued)
October 31, 2017

Note 2. Significant Accounting Policies (continued)

share of segregated customer funds available. It is possible that the recovery amount could be less than the total of cash and other equity deposited.

I) FORWARD FOREIGN CURRENCY CONTRACTS — A forward foreign currency exchange contract ("forward currency contract") is a commitment to purchase or sell a foreign currency at the settlement date at a negotiated rate. The Fund will enter into forward currency contracts primarily for hedging foreign currency risk. Forward currency contracts are valued at the prevailing forward exchange rate of the underlying currencies and unrealized gain/loss is recorded daily. On the settlement date of the forward currency contract, the Fund records a realized gain or loss equal to the difference between the value of the contract at the time it was opened and the value of the contract at the time it was closed. Certain risks may arise upon entering into forward currency contracts from the potential inability of counterparties to meet the terms of their contracts. The maximum counterparty credit risk to the Fund is measured by the unrealized gain on appreciated contracts. Additionally, when utilizing forward currency contracts to hedge, the Fund forgoes the opportunity to profit from favorable exchange rate movements during the term of the contract. The Fund's open forward currency contracts at October 31, 2017 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 October 31, 2017.

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

43

Credit Suisse Strategic Income Fund
Notes to Financial Statements (continued)
October 31, 2017

Note 2. Significant Accounting Policies (continued)

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 October 31, 2017 and during the year ended October 31, 2017, there were no securities out on loan.

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

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

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 — On August 26, 2016, Financial Accounting Standards Board ("FASB") issued Accounting Standards Update No. 2016-15, "Statement of Cash Flows (Topic 230), a consensus of the FASB's Emerging Issues Task Force" ("ASU 2016-15"). ASU 2016-15 is intended to reduce diversity in practice in how certain transactions are classified in the statement of cash flows. The issues addressed in ASU 2016-15 are: debt prepayment or debt extinguishment costs, settlement of zero-coupon debt instruments, contingent consideration payments made after a business combination, proceeds from the settlement of insurance claims, proceeds from

44

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

Note 2. Significant Accounting Policies (continued)

the settlement of corporate-owned life insurance policies, including bank-owned life insurance policies, distributions received from equity method investments, beneficial interests in securitization transactions; and, separately identifiable cash flows and application of the predominance principle. ASU 2016-15 is effective for interim and annual reporting periods beginning after December 15, 2017. Management is currently evaluating the impact, if any, of applying this provision.

In November 2016, FASB issued Accounting Standards Update No. 2016-18, "Statement of Cash Flows (Topic 230), Restricted Cash, a consensus of the FASB's Emerging Issues Task Force" ("ASU 2016-18"). ASU 2016-18 requires that a statement of cash flows explains the change during the period in the total of cash, cash equivalents, and amounts generally described as restricted cash or restricted cash equivalents. Therefore, amounts generally described as restricted cash and restricted cash equivalents should be included with cash and cash equivalents when reconciling the beginning-of-period and end-of-period total amounts shown on the statement of cash flows. The amendments in ASU 2016-18 do not provide a definition of restricted cash or restricted cash equivalents. ASU 2016-18 is effective for interim and annual reporting periods beginning after December 15, 2017. Management is currently evaluating the impact, if any, of applying this provision.

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 October 31, 2017, 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.

This contract may not be terminated before February 28, 2018.

Note 7. Income Tax Information and Distributions to Shareholders

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

The tax character of dividends paid by the Fund during the years ended October 31, 2017 and 2016, respectively, was as follows:

Ordinary Income				Return of Capital
2017		2016		2017		2016
$	6,289,715	$	6,202,299	$	236,908	$	—

The tax basis components of distributable earnings differ from the amounts reflected in the Statement of Assets and Liabilities by temporary book/tax differences. These differences are primarily due to differing treatments of dividends payable, wash sales, forwards and futures contracts marked to

Note 7. Income Tax Information and Distributions to Shareholders (continued)

market and deferred organizational expenses. At October 31, 2017, the components of distributable earnings on a tax basis were as follows:

Accumulated net realized loss	$	(6,195,007	)
Unrealized depreciation		(514,433	)
	$	(6,709,440	)

At October 31, 2017, the Fund had $1,481,306 of unlimited short-term capital loss carryforwards and $4,713,701 of unlimited long-term capital loss carryforwards available to offset possible future capital gains.

At October 31, 2017, the cost and net unrealized appreciation (depreciation) of investments and derivatives for income tax purposes were as follows:

Cost of Investments	$	188,055,662
Unrealized appreciation	$	3,852,489
Unrealized depreciation		(4,244,388	)
Net unrealized appreciation (depreciation)	$	(391,899	)

To adjust for current period permanent book/tax differences which arose principally from differing book/tax treatment of foreign currency gain (loss) and distribution re-designations, paid-in capital was charged $1,300, distributions in excess of net investment income was charged $224,653 and accumulated net realized loss was credited $225,953. Net assets were not affected by these reclassifications.

Note 8. 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.

Report of Independent Registered Public Accounting Firm

The Board of Trustees and Shareholders
Credit Suisse Strategic Income Fund:

We have audited the accompanying statement of assets and liabilities of Credit Suisse Strategic Income Fund (the "Fund"), a series of the Credit Suisse Opportunity Funds, including the schedule of investments, as of October 31, 2017, and the related statement of operations for the year then ended, the statements of changes in net assets for each of the years in the two-year period then ended, and the financial highlights for each of the years in the three-year period then ended. These financial statements and financial highlights are the responsibility of the Fund's management. Our responsibility is to express an opinion on these financial statements and financial highlights based on our audits. The accompanying financial highlights of the Fund for each of the years in the two-year period ended October 31, 2014 were audited by other independent registered public accountants whose report thereon dated December 29, 2014, expressed an unqualified opinion on those financial highlights.

We conducted our audits in accordance with the standards of the Public Company Accounting Oversight Board (United States). Those standards require that we plan and perform the audits to obtain reasonable assurance about whether the financial statements and financial highlights are free of material misstatement. An audit includes examining, on a test basis, evidence supporting the amounts and disclosures in the financial statements. Our procedures included confirmation of securities owned as of October 31, 2017, by correspondence with the custodian and broker or by other appropriate auditing procedures. An audit also includes assessing the accounting principles used and significant estimates made by management, as well as evaluating the overall financial statement presentation. We believe that our audits provide a reasonable basis for our opinion.

In our opinion, the financial statements and financial highlights referred to above present fairly, in all material respects, the financial position of Credit Suisse Strategic Income Fund as of October 31, 2017, the results of its operations for the year then ended, the changes in its net assets for each of the years in the two-year period then ended, and the financial highlights for each of the years in the three-year period then ended in conformity with U.S. generally accepted accounting principles.
