CREDIT SUISSE HIGH INCOME FUND ANNUAL INVESTMENT ADVISER'S REPORT October 31, 2005 (unaudited) - -------------------------------------------------------------------------------- November 23, 2005 Dear Shareholder: PERFORMANCE SUMMARY 11/01/04 - 10/31/05 FUND & BENCHMARKS PERFORMANCE Common Class 1 3.02% Class A 1,2 2.75% Class B 1,2 1.91% Class C 1,2 1.91% Citigroup High-Yield Market Index 3 (CHYMI) 3.55% Lipper High Yield Bond Funds Index 3 4.12% Performance for the Fund's Class A, Class B and Class C shares is without the maximum sales charge of 4.75%, 4.00% and 1.00%, respectively. 2 MARKET OVERVIEW: A SHIFT IN THE CYCLE In the Fund's fiscal year high yield outperformed the broad fixed income market (as measured by the Lehman Brothers Aggregate Bond Index 4 , which returned 1.13%), although the magnitude of outperformance narrowed significantly from that of the last several years. In our view, this was due to the natural progress of the credit and business cycles. After intense focus on balance sheet repair prompted by strong earnings growth and low interest rates, corporations are increasingly turning to address their lackluster share prices (through share repurchases, dividend increases and other measures) in an effort to boost shareholder value. But while a number of signs suggest to us that the shift in the corporate credit cycle is clearly underway, credit fundamentals remain sound. Other signs of the market's transitional nature include the issuer default rate (as measured by Moody's Investor Services), which remained below 2% through the entire fiscal year period. Though Moody's now expects defaults to rise toward 3.2% by September of 2006, that number is well below its historical average. As for valuations, spreads also remained below their historical averages for most of the period, but widened dramatically with the downgrade of General Motors and Ford to junk status. These fallen angels brought approximately $82 billion of debt (market value prior to downgrade) and a spike in volatility into the high yield market. Together they now account for about 12% of the index. (As of October 31, 2005, the Fund's exposure to these companies consisted of a 0.7% weighting in Ford Credit Co. securities and a 2.4% weighting in General Motors Acceptance Co. securities.) 1 CREDIT SUISSE HIGH INCOME FUND ANNUAL INVESTMENT ADVISER'S REPORT (CONTINUED) October 31, 2005 (unaudited) - -------------------------------------------------------------------------------- In our view, this influx of fallen angel debt caused the greatest turbulence, and provided the greatest drag, on the high yield market in the period. Although the fiscal year saw a 35% decline in the number of high yield deals and a 32% drop in new issue volume, this decrease in new supply was easily outweighed by the entrance of Ford, GM and Delphi debt into the high yield arena. Meanwhile, on the demand side, high yield mutual funds reported an $8.3 billion outflow through October 2005 compared to a $3.2 billion outflow during the same period in 2004, but this indicator does not account for the increasing role of hedge funds and other market participants. In sum, all of these factors, along with the impact of the Gulf Coast hurricanes, growing inflation concerns due to persistently high energy costs, and the general absence of any significant positive momentum in the space, weighed on the market, resulting in greater caution among investors. STRATEGIC REVIEW: SECTOR AND SECURITY SELECTION DRIVE PERFORMANCE The Fund underperformed its CHYMI benchmark primarily due to its relative positioning in underperforming industry sectors. Most notably, while we had positive issue selection within the Diversified Telecommunications industry, it was also our largest underweight relative to the Index, and one of this year's better performing sectors. We were also underweight to the Energy sector, which like Telecommunications was one of the year's winners. On the positive side, aiding performance in the period was our significant overweight to the Wireless sector, which was among the best performing industries in high yield this year. Another sector decision that contributed positively to performance was our underweight to Airlines, an industry that has seen its margins squeezed by high energy costs and has suffered a number of high profile bankruptcies in the past year. OUTLOOK: RATES AND RISK AVERSION ON THE RISE Looking ahead, we believe that high energy prices and broad inflation fears could eventually prove to be a drag on earnings and a potential disruption to economic growth. Although corporate credit fundamentals remain sound, we expect issuer specific event risk to rise. Therefore, security selection will be a critical driver of performance going forward and we will focus on those issues experiencing stable or improving margins and cash flows. 2 CREDIT SUISSE HIGH INCOME FUND ANNUAL INVESTMENT ADVISER'S REPORT (CONTINUED) October 31, 2005 (unaudited) - -------------------------------------------------------------------------------- In addition, fed funds futures are currently pricing in a target rate of 4.25% by year-end 2005, another potential catalyst for market weakness ahead. With each step in the Federal Reserve's measured pace of monetary tightening, the market has registered slightly greater risk aversion; low yields and tight spreads only increase the vulnerability to interest rate risk. We will therefore remain cautious on the most interest rate sensitive securities. Credit Suisse High Yield Management Team Michael E.

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 month period ended October 31, 2005. The table illustrates your Fund's expenses in two ways: o 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 under the share class you hold. o HYPOTHETICAL 5% FUND RETURN. This helps you to compare your 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. 7 CREDIT SUISSE HIGH INCOME FUND ANNUAL INVESTMENT ADVISER'S REPORT (CONTINUED) October 31, 2005 (unaudited) - -------------------------------------------------------------------------------- EXPENSES AND VALUE OF A $1,000 INVESTMENT FOR THE SIX MONTH PERIOD ENDED OCTOBER 31, 2005 - -------------------------------------------------------------------------------- COMMON ACTUAL FUND RETURN CLASS CLASS A CLASS B CLASS C --------- --------- --------- --------- Beginning Account Value 5/1/05 $1,000.00 $1,000.00 $1,000.00 $1,000.00 Ending Account Value 10/31/05 $1,034.30 $1,033.00 $1,029.10 $1,029.10 Expenses Paid per $1,000* $ 4.36 $ 5.64 $ 9.46 $ 9.46 HYPOTHETICAL 5% FUND RETURN Beginning Account Value 5/1/05 $1,000.00 $1,000.00 $1,000.00 $1,000.00 Ending Account Value 10/31/05 $1,020.92 $1,019.66 $1,015.88 $1,015.88 Expenses Paid per $1,000* $ 4.33 $ 5.60 $ 9.40 $ 9.40 COMMON CLASS CLASS A CLASS B CLASS C --------- --------- --------- --------- ANNUALIZED EXPENSE RATIOS* 0.85% 1.10% 1.85% 1.85% ________________ * 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 THE NUMBER OF DAYS IN THE MOST RECENT FISCAL HALF YEAR PERIOD, THEN DIVIDED BY 365.

See Accompanying Notes to Financial Statements. 35 CREDIT SUISSE HIGH INCOME FUND NOTES TO FINANCIAL STATEMENTS October 31, 2005 - -------------------------------------------------------------------------------- NOTE 1. ORGANIZATION Credit Suisse High Income Fund (the "Fund"), a portfolio of the Credit Suisse Opportunity Funds (the "Trust"), a Delaware business 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 is authorized to offer four Classes of shares: Common Class, Class A shares, Class B shares and Class C shares. Each class of shares represents an equal pro rata interest in the Fund, except that they bear different expenses which reflect the differences in the range of services provided to them. Effective December 12, 2001, Common Class shares closed to new investments, except for reinvestments of dividends. Common Class shareholders may continue to hold Common Class shares but may not add to their accounts. Although no further shares can be purchased, shareholders can redeem their Common Class shares through any available method. Class A shares are sold subject to a front-end sales charge up to 4.75%. Class B shares are sold subject to a contingent deferred sales charge which declines from 4.00% to zero depending on the period of time the shares are held. Class C shares are sold subject to a contingent deferred sales charge of 1.00% if redeemed within the first year of purchase. NOTE 2. SIGNIFICANT ACCOUNTING POLICIES 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. Debt securities with a remaining maturity greater than 60 days are valued in accordance with the price supplied by a pricing service, which may use a matrix, formula or other objective method that takes into consideration market indices, yield curves and other specific adjustments. Debt obligations that will mature in 60 days or less are valued on the basis of amortized cost, which approximates market value, unless it is determined that using this method would not represent fair value. The Fund's equity investments are valued at market value, which is generally determined using the closing price on the exchange or market on which the security is primarily traded at the time of valuation (the "Valuation Time"). If no sales are reported, equity investments 36 CREDIT SUISSE HIGH INCOME FUND NOTES TO FINANCIAL STATEMENTS (CONTINUED) October 31, 2005 - -------------------------------------------------------------------------------- NOTE 2. SIGNIFICANT ACCOUNTING POLICIES are generally valued at the most recent bid quotation as of the Valuation Time or at the lowest asked quotation in the case of a short sale of securities. Investments in mutual funds are valued at the mutual fund's closing net asset value per share on the day of valuation. Securities and other assets for which market quotations are not readily available, or whose values have been materially affected by events occurring before the Fund's Valuation Time but after the close of the securities' primary markets, are valued at fair value as determined in good faith by, or under the direction of, the Board of Trustees under procedures established by the Board of Trustees. The Fund may utilize a service provided by an independent third party which has been approved by the Board of Trustees to fair value certain securities. When fair-value pricing is employed, the price of securities used by a fund to calculate its net asset value may differ from quoted or published prices for the same securities. B) SECURITY TRANSACTIONS AND INVESTMENT INCOME -- Security transactions are accounted for on a trade date basis. Interest income is recorded on the accrual basis. Dividends are recorded on the ex-dividend date. Certain expenses are class-specific expenses and vary by 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. C) DIVIDENDS AND DISTRIBUTIONS TO SHAREHOLDERS -- Dividends from net investment income 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. Income and capital gain distributions are determined in accordance with federal income tax regulations, which may differ from accounting principles generally accepted in the United States of America ("GAAP"). D) FEDERAL INCOME TAXES -- No provision is made for federal taxes as it is the Fund's intention to have the fund continue to qualify for and elect the tax treatment applicable to regulated investment companies under the Internal Revenue Code of 1986, as amended, 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 HIGH INCOME FUND NOTES TO FINANCIAL STATEMENTS (CONTINUED) October 31, 2005 - -------------------------------------------------------------------------------- NOTE 2. SIGNIFICANT ACCOUNTING POLICIES E) USE OF ESTIMATES -- The preparation of financial statements in conformity with GAAP requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities at the date of the financial statements and the reported amounts of revenues and expenses during the reporting period. Actual results could differ from these estimates. F) SHORT-TERM INVESTMENTS -- The Fund, together with other funds/portfolios advised by Credit Suisse Asset Management, LLC ("CSAM"), an indirect, wholly-owned subsidiary of Credit Suisse Group, pools available cash into either a short-term variable rate time deposit issued by State Street Bank and Trust Company ("SSB"), the Fund's custodian, or a money market fund advised by CSAM. The short-term time deposit issued by SSB is a variable rate account classified as a short-term investment. G) TBA PURCHASE COMMITMENTS -- The Fund may enter into "TBA" (to be announced) purchase commitments to purchase securities for a fixed price at a future date, typically not exceeding 45 days. TBA purchase commitments may be considered securities in themselves, and involve a risk of loss if the value of the security to be purchased declines prior to settlement date. This risk is in addition to the risk of decline in the Fund's other assets. Unsettled TBA purchase commitments are valued at the current market value of the underlying securities, according to the procedures described above under "Security Valuation". H) SECURITIES LENDING - Loans of securities are required at all times to be secured by collateral at least equal to 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). 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 CSAM and may be invested in a variety of investments, including certain CSAM-advised funds, funds advised by SSB, the Fund's securities lending agent, or money market instruments. However, in the event of default or bankruptcy by the other party to the agreement, realization and/or retention of the collateral may be subject to legal proceedings. SSB has been engaged by the Fund to act as the Fund's securities lending agent. The Fund's securities lending arrangement provides that the Fund and 38 CREDIT SUISSE HIGH INCOME FUND NOTES TO FINANCIAL STATEMENTS (CONTINUED) October 31, 2005 - -------------------------------------------------------------------------------- NOTE 2. SIGNIFICANT ACCOUNTING POLICIES SSB will share the net income earned from the securities lending activities. During the year ended October 31, 2005, total earnings from the fund's investment in cash collateral received in connection with security lending arrangements was $1,427,453 of which $1,171,215 was rebated to borrowers (brokers). The fund retained $180,195 in income from the cash collateral investment and SSB, as lending agent, was paid $76,043. The Fund may also be entitled to certain minimum amounts of income from its securities lending activities. Securities lending income is accrued as earned. I) OTHER -- Lower-rated debt securities (commonly known as "junk bonds") possess speculative characteristics and are subject to greater market fluctuations and risk of lost income and principal than higher-rated debt securities for a variety of reasons. Also, during an economic downturn or substantial period of rising interest rates, highly leveraged issuers may experience financial stress which would adversely affect their ability to service their principal and interest payment obligations, to meet projected business goals and to obtain additional financing. In addition, periods of economic uncertainty and changes can be expected to result in increased volatility of market prices of lower-rated debt securities and (to the extent the Fund invests in junk bonds) the Fund's net asset value.

NOTE 7. FEDERAL INCOME TAXES Income and capital gain distributions are determined in accordance with federal income tax regulations, which may differ from GAAP. The tax characteristics of dividends and distributions paid during the years ended October 31, 2005 and 2004 by the Fund were as follows: ORDINARY INCOME LONG-TERM CAPITAL GAIN --------------- ---------------------- 2005 2004 2005 2004 ---- ---- ---- ---- $ 17,449,559 $ 20,936,194 $ 3,854,792 $ -- 42 CREDIT SUISSE HIGH INCOME FUND NOTES TO FINANCIAL STATEMENTS (CONTINUED) October 31, 2005 - -------------------------------------------------------------------------------- NOTE 7. FEDERAL INCOME TAXES 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 losses deferred on wash sales and income from defaulted bonds. At October 31, 2005, the components of distributable earnings on a tax basis for the Fund were as follows: Undistributed net investment income $ 326,728 Accumulated Long-term capital gains 4,138,984 Unrealized appreciation 1,096,975 ----------- $ 5,562,687 =========== At October 31, 2005, the Fund had no capital loss carryforwards available to offset possible future capital gains. At October 31, 2005, the identified cost for federal income tax purposes, as well as the gross unrealized appreciation from investments for those securities having an excess of value over cost, gross unrealized depreciation from investments for those securities having an excess of cost over value and the net unrealized appreciation from investments were $188,290,936, $5,707,865, ($4,610,890) and $1,096,975, respectively. At October 31, 2005, the Fund reclassified $428,847 from accumulated net realized gain from investments to undistributed net investment loss, to adjust for current period permanent book/tax differences which arose principally from differing book/tax treatments of paydowns and defaulted bonds. 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. 43 CREDIT SUISSE HIGH INCOME FUND REPORT OF INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM - -------------------------------------------------------------------------------- To the Board of Trustees and Shareholders of Credit Suisse High Income Fund: In our opinion, the accompanying statement of assets and liabilities, including the schedule of investments, and the related statements of operations and of changes in net assets and the financial highlights present fairly, in all material respects, the financial position of Credit Suisse High Income Fund (the "Fund") at October 31, 2005, the results of its operations for the year then ended, the changes in its net assets for each of the two years in the period then ended and the financial highlights for each of the five years in the period then ended, in conformity with accounting principles generally accepted in the United States of America. These financial statements and financial highlights (hereafter referred to as "financial statements") are the responsibility of the Fund's management; our responsibility is to express an opinion on these financial statements based on our audits. We conducted our audits of these financial statements in accordance with the standards of the Public Company Accounting Oversight Board (United States). Those standards require that we plan and perform the audit to obtain reasonable assurance about whether the financial statements are free of material misstatement. An audit includes examining, on a test basis, evidence supporting the amounts and disclosures in the financial statements, assessing the accounting principles used and significant estimates made by management, and evaluating the overall financial statement presentation. We believe that our audits, which included confirmation of securities at October 31, 2005 by correspondence with the custodian and brokers, provide a reasonable basis for our opinion.
