CS Floating Rate High Income Fund Share Class C

¹) Credit Suisse Opportunity Funds (the “Trust”) and UBS Asset Management (Americas) LLC (“UBS”) have entered into a written contract limiting operating expenses to 0.96% of the fund’s average daily net assets for Class A shares, 1.71% of the fund’s average daily net assets for Class C shares and 0.71% of the fund’s average daily net assets for Class I shares at least through February 28, 2024. This limit excludes certain expenses, including interest charges on fund borrowings, taxes, brokerage commissions, dealer spreads and other transaction charges, expenditures that are capitalized in accordance with generally accepted accounting principles, acquired fund fees and expenses, short sale dividends, and extraordinary expenses (e.g., litigation and indemnification and any other costs and expenses that may be approved by the Board of Trustees). The Trust is authorized to reimburse UBS for management fees previously limited and/or for expenses previously paid by UBS, provided, however, that any reimbursements must be paid at a date not more than thirty-six months following the applicable month during which such fees were limited or expenses were reimbursed by UBS 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, 2024.

²) The current maximum initial sales charge for Class A shares is 4.75%, and is waived with respect to certain investment advisory clients, investors in employee retirement, stock, bonus, pension or profit-sharing plans, certain registered investment advisers and broker-dealers with clients participating in comprehensive fee programs, and certain other investors. The current maximum contingent deferred sales charge (CDSC) for Class C shares is 1.00% during the first year.
