May 15, 2007

Dear Shareholder:

Performance Summary

11/01/06 – 04/30/07

Fund & Benchmarks	Performance
Total Return (based on NAV)¹		10.72	%
Total Return (based on market value)¹		5.18	%
Merrill Lynch US High Yield Master II Constrained Index²		6.94	%

Market Review: A Strong Market and Strong Performance

As of April 30, 2007, the U.S. high yield market experienced six consecutive months of positive returns, totaling 6.94% (as measured by the Fund's benchmark).

Lower-rated issuers continued to outperform the broader market, with CCC-rated securities returning 10.61% for the period. B-rated securities, performed in-line with the market at 6.98%, while BB-rated securities underperformed at 5.47%. High yield spreads continued to tighten relative to the 10-year Treasury, narrowing 51 basis points to end the period at 287 basis points versus treasuries.

Credit fundamentals continued to be firm as default rates reported by Moody's showed a slight drop, from 1.67% in October 2006 to 1.45% in April 2007. Additionally, the distress ratio, a leading indicator for future default rates, has remained at 15-year lows of 1.2% for the past three months.

Against this fundamental backdrop, the technical environment has also been positive, with the new issue calendar remaining manageable and well-received. During the period, almost $110 billion in new issues came into the high yield market. Over the past few months, there have been consistent inflows into high yield mutual funds in addition to demand from coupon and bond redemptions.

Over the period, nearly all sectors posted positive returns with little variance among them. Sectors enjoying out-performance included health services, theaters and non-food & drug retailers — all posting above 9% returns.

Strategic Review and Outlook: Market Conditions Support Valuations

For the semiannual period ended April 30, 2007, the Fund's total return based on NAV was 10.72% as compared to 6.94% for the benchmark. Contributing to performance was an overweight to lower rated securities. An underweight to BB-rated securities also aided performance. Further, superior sector and/or security selection in building materials, media-cable, support-services, consumer products and auto parts also contributed to performance. An underweight to media-services hurt relative returns.

At the sector level, we remain constructive on corporate spending and the commercial cycle broadly. Additionally, we are maintaining an overweight in the cable sector as we expect product bundling will continue to support subscriber and margin growth.

Recent equity volatility has proven that the high yield market is vulnerable to external shocks and may display some volatility in the future. Given the sound fundamental backdrop, we have used these circumstances to selectively add to credits, as we believe these market conditions support current valuations and forecast that the market will remain range-bound going forward.

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.

In addition to historical information, this report contains forward-looking statements that may concern, among other things, domestic and foreign market, 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.

We wish to remind shareholders about the Fund's dividend reinvestment program known as the Investlink^SM Program (the "Program"). The Program is sponsored and administered by Computershare Trust Company N.A. ("Computershare"), not by the Fund. Computershare will act as program administrator (the "Program Administrator") of the Program. The purpose of the Program is to provide existing shareholders with a simple and convenient way to invest additional funds and reinvest dividends in shares of the Fund's common stock. The enrollment form and information relating to the Program (including the terms and conditions) may be obtained by calling the Program Administrator at one of the following telephone numbers: (800) 730-6001 (U.S and Canada) or (781) 575-3100 (outside U.S. and Canada). All correspondence regarding the Program should be directed to: Computershare Trust Company, N.A., InvestLink^SM Program, P.O. Box 43010, Providence, RI 02940-3010

Credit Suisse High Yield Bond Fund
Notice to Shareholders

At the time Credit Suisse High Yield Bond Fund (the "Fund") commenced operations in 1998, the Prospectus did not contemplate the use of credit default swaps as such strategies were not commonly used by investment companies. Since then the use of credit default swaps has proliferated. Credit Suisse now believes that the use of the credit default swaps discussed below may permit it to better manage the risk and returns of the Fund and effective May 1, 2007, the Fund may, in the discretion of the portfolio managers, use credit default swaps. 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 "buyer" in a credit default swap is obligated to pay the "seller" an upfront payment or a periodic stream of payments over the term of the agreement, provided that no credit event on an underlying reference obligation has occurred. If a credit event occurs, the seller must pay the buyer the full notional value, or "par value," of the reference obligation in exchange for the reference obligation. As a result of counterparty risk, credit default swap agreements involve greater risks than if the Fund had invested in the reference obligation directly.

If the Fund is a buyer and no credit event occurs, the cost to the Fund is the premium paid with respect to the agreement. If a credit event occurs, however, the Fund may elect to receive the full notional value of the swap in exchange for an equal face amount of deliverable obligations of the reference entity that may have little or no value. On the other hand, the value of any deliverable obligations paid by the Fund to the seller, coupled with the up front or periodic payments previously received by the seller, may be less than the full notional value the seller pays to the Fund, resulting in a loss of value to the Fund.

If the Fund is a seller and no credit event occurs, the Fund would generally receive an up front payment or a fixed rate of income throughout the term of the swap, which typically is between six months and three years. If a credit event occurs, however, generally the Fund would have to pay the buyer the full notional value of the swap in exchange for an equal face amount of deliverable obligations of the reference entity that may have little or no value. When the Fund acts as a seller of a credit default swap agreement it is exposed to speculative exposure risk since, if a credit event occurs, the Fund may be required to pay the buyer the full notional value of the contract net of any amounts owed by the buyer related to its delivery of deliverable obligations of the reference entity. As a result, the Fund bears the entire risk of loss due to a decline in value of a referenced security on a credit default swap it has sold if there is a credit event with respect to the security. The Fund bears the same risk as a buyer of fixed income securities directly. The Fund will sell a credit derivative only with respect to securities in which it would be authorized to invest.

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

As the seller of a credit default swap the Fund would be subject to investment exposure on the notional amount of the swap. Accordingly, the Fund will segregate liquid investments in an amount equal to the aggregate market value of the of the credit default swaps of which it is the seller, marked to market on a daily basis. Segregated assets cannot be sold or transferred unless equivalent assets are substituted in their place or it is no longer necessary to segregate them. As a result, there is the possibility that segregation of a large percentage of the Fund's assets could

Credit Suisse High Yield Bond Fund
Notice to Shareholders (continued)

impede portfolio management or the Fund's ability to meet current obligations. The notional amount of the aggregate credit exposure to which the Fund is subject, plus the market value of the Fund's investments in credit derivatives and/or premiums paid therefor as a buyer of credit derivatives, may not exceed the Fund's total assets.

When the Fund buys or sells a credit derivative, the underlying issuer (s) or obligor(s) as well as the counterparty to the transaction will be treated as an issuer for purposes of complying with the Fund's issuer diversification and industry concentration policies, absent regulatory guidance to the contrary. The Fund may, but is not required to, use credit swaps or any other credit derivative. There is no assurance that credit derivatives will be available at any time or, if used, that the derivatives will be used successfully.

Tax Considerations. Periodic net payments will constitute ordinary income or deductions, while termination of a swap will result in capital gain or loss (which will be long-term capital gain or loss if the Fund has been a party to the swap for more than one year). The tax treatment of many types of credit default swaps is uncertain.

Credit Suisse High Yield Bond Fund

Notes to Financial Statements

April 30, 2007 (unaudited)

Note 1. Organization

Credit Suisse High Yield Bond Fund (the "Fund") is a business trust organized under the laws of the State of Delaware on April 30, 1998. The Fund is registered with the Securities and Exchange Commission under the Investment Company Act of 1940, as amended ("Investment Company Act"), as a non-diversified, closed-end management investment company. The Fund's primary objective is to seek high current income.

The following is a summary of significant accounting policies consistently followed by the Fund in its operations and in connection with the preparation of its financial statements.

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. 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 ("Valuation Time"). If no sales are reported, equity investments 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 direction of, the Board of Trustees under procedures established by the Board of Trustees. At April 30, 2007, the Fund held 0.08% of its net assets in securities valued at fair value as determined in good faith under procedures established by the Board of Trustees with an aggregate cost of $4,364,635 and fair value of $204,669. The Fund's estimate of fair value assumes a willing buyer and a willing seller neither acting under the compulsion to buy or sell. Although these securities may be resold in privately negotiated transactions, the prices realized on such sales could differ from the prices originally paid by the Fund or the current carrying values, and the difference could be material.

B) 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. Translation gains or losses resulting from changes in the exchange rate during the reporting period and realized gains and losses on the settlement of foreign currency transactions are reported in the results of operations for the current period. The Fund does not isolate that portion of realized gains and losses on investments in equity securities which is due to changes in the foreign exchange rate from that which is due to changes in market prices of equity securities. The Fund isolates that portion of realized gains and losses on investments in debt securities which is due to changes in the foreign exchange rate from that which is due to changes in market prices of debt securities.

C) 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. The cost of investments sold is determined by use of the specific identification method for both financial reporting and income tax purposes.

Credit Suisse High Yield Bond Fund

Notes to Financial Statements (continued)

April 30, 2007 (unaudited)

D) DIVIDENDS AND DISTRIBUTIONS TO SHAREHOLDERS — The Fund declares and pays dividends on a monthly basis. 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 dividends and capital gain distributions are determined in accordance with income tax regulations, which may differ from accounting principles generally accepted in the United States of America ("GAAP"). These differences are primarily due to differing treatments of income and gains on various investment securities held by the Fund, timing differences and differing characterization of distributions made by the Fund.

The Fund's dividend policy is to distribute substantially all of its net investment income to its shareholders on a monthly basis. However, in order to provide shareholders with a more consistent yield to the current trading price of shares of beneficial interest of the Fund, the Fund may at times pay out less than the entire amount of net investment income earned in any particular month and may at times in any month pay out such accumulated but undistributed income in addition to net investment income earned in that month. As a result, the dividends paid by the Fund for any particular month may be more or less than the amount of net investment income earned by the Fund during such month.

E) FEDERAL INCOME TAXES — No provision is made for federal taxes as it is the Fund's intention to 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.

F) CASH FLOW INFORMATION — Cash, as used in the Statement of Cash Flows, is the amount reported in the Statement of Assets and Liabilities. The Fund invests in securities and distributes dividends from net investment income and net realized gains, if any (which are either paid in cash or reinvested at the discretion of shareholders). These activities are reported in the Statement of Changes in Net Assets. Information on cash payments is presented in the Statement of Cash Flows. Accounting practices that do not affect reporting activities on a cash basis include unrealized gain or loss on investment securities and accretion or amortization income recognized on investment securities.

G) 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 income and expenses during the reporting period. Actual results could differ from those estimates.

H) SECURITIES LENDING — Loans of securities are required at all times to be secured by collateral at least equal to 100% of the market value of domestic securities on loan (including any accrued interest thereon). Cash collateral received by the Fund in connection with securities lending activity is reinvested into either fully collateralized repurchase agreements with Bear, Stearns & Co., Inc. (an affiliate of the custodian, Custodial Trust Company, and the borrower, Bear, Stearns Securities Corp. (the "Borrower")), registered money market mutual funds (subject to regulatory limitations) or some combination thereof. In the event of default or bankruptcy by the Borrower or its affiliates to the agreement, realization and/or retention of the Fund's collateral may be subject to legal proceedings.

The Fund's securities lending arrangement provides that the Fund and the Borrower will share the net income earned from the securities lending activities. During the six months ended April 30, 2007, total earnings from the Fund's investment in cash collateral received in connection with the securities lending arrangement was $1,673,447 of which $1,505,317 was rebated to the Borrower. The Fund retained $168,130 in income from the cash collateral

investment. The Fund is entitled to a certain minimum amount of income from its securities lending activities. Securities lending income is accrued as earned.

I) FORWARD FOREIGN CURRENCY CONTRACTS — The Fund may enter into forward foreign currency contracts for the purchase or sale of a specific foreign currency at a fixed price on a future date. Risks may arise upon entering into these contracts from the potential inability of counterparties to meet the terms of their contracts and from unanticipated movements in the value of a foreign currency. The Fund will enter into forward foreign currency contracts primarily for hedging purposes. Forward foreign currency contracts are adjusted by the daily exchange rate of the underlying currency and any gains or losses are recorded for financial statement purposes as unrealized until the contract settlement date or an offsetting position is entered into. At April 30, 2007, the Fund had the following open forward foreign currency contracts:

Forward Foreign Currency Contract	Expiration Date	Foreign Currency To Be Bought		Contract Amount		Contract Value		Unrealized Gain
British Pound	6/28/2007	£	530,000	$	1,041,779	$	1,059,639	$	17,860
European Economic Unit	6/28/2007	€	1,406,000		1,884,532		1,924,988		40,456
				$	2,926,311	$	2,984,627	$	58,316

Note 3. Transactions with Affiliates and Related Parties

The Fund has entered into an Investment Advisory Agreement (the "Advisory Agreement") with Credit Suisse Asset Management, LLC ("Credit Suisse"). The Advisory Agreement provides for a fee at the annual rate of 1.00% of the first $250 million of the average weekly value of the Fund's total assets minus the sum of liabilities (other than aggregate indebtedness constituting leverage) and 0.75% of the average weekly value of the Fund's total assets minus the sum of liabilities (other than aggregate indebtedness constituting leverage) greater than $250 million. Effective January 1, 2007, Credit Suisse agreed to waive 0.15% of the fees payable under the Advisory Agreement. For the six months ended April 30, 2007, investment advisory fees earned were $1,439,683.

State Street Bank and Trust Company ("SSB") serves as Accounting and Administrative Agent for the Fund. For its 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 relative average net assets of each fund/portfolio, subject to an annual minimum fee. For the six months ended April 30, 2007, administrative services fees earned by SSB (including out-of-pocket expenses) were $56,066.

The Independent Trustees receive fifty percent (50%) of their annual retainer in the form of shares purchased by the Fund's transfer agent in the open market.

Merrill Corporation ("Merrill"), an affiliate of Credit Suisse, has been engaged by the Fund to provide certain financial printing and fulfillment services. For the six months ended April 30, 2007, Merrill was paid $27,087 for its services to the Fund.

Note 4. Line of Credit

The Fund has a $150 million line of credit provided by Citibank North America, Inc., under a Revolving Credit and Security Agreement (the "Agreement") dated April 12, 2002, as amended from time to time, primarily to leverage its investment portfolio. Under this Agreement, the Fund may borrow the lesser of $150 million or 33¹/₃% of its gross assets. Interest is payable at the Bank's Base Rate plus a commission of 0.05%. The Fund pays a program fee of 0.20% of the average daily amount leveraged, an administration fee of 0.02% of the average daily amount leveraged and a liquidity fee of 0.15% of the maximum borrowing limit (currently $150 million). The Agreement

Credit Suisse High Yield Bond Fund

Notes to Financial Statements (continued)

April 30, 2007 (unaudited)

requires, among other provisions, that the percentage obtained by dividing total indebtedness for money borrowed by total assets of the Fund shall not exceed 33¹/₃%. At April 30, 2007 the Fund had loans outstanding under the Agreement of $111,000,000. During the six months ended April 30, 2007, the Fund had borrowings under the Agreement as follows:

Average Daily Loan Balance				Weighted Average Interest Rate				Maximum Daily Loan Outstanding
$	110,668,508				5.328	%		$	111,000,000

The use of leverage by the Fund creates an opportunity for increased net income and capital appreciation for the Fund, but, at the same time, creates special risks, and there can be no assurance that a leveraging strategy will be successful during any period in which it is employed. The Fund intends to utilize leverage to provide the Shareholders with a potentially higher return. Leverage creates risks for Shareholders including the likelihood of greater volatility of net asset value and market price of the Fund's shares and the risk that fluctuations in interest rates on borrowings and short-term debt may affect the return to Shareholders. To the extent the income or capital appreciation derived from securities purchased with funds received from leverage exceeds the cost of leverage, the Fund's return will be greater than if leverage had not been used. Conversely, if the income or capital appreciation from the securities purchased with such funds is not sufficient to cover the cost of leverage, the return to the Fund will be less than if leverage had not been used, and therefore the amount available for distribution to Shareholders as dividends and other distributions will be reduced. In the latter case, Credit Suisse in its best judgment nevertheless may determine to maintain the Fund's leveraged position if it deems such action to be appropriate under the circumstances. During periods in which the Fund is utilizing leverage, the Management Fee will be higher than if the Fund did not utilize a leveraged capital structure because the fee is calculated as a percentage of the Managed Assets including those purchased with leverage. Certain types of borrowings by the Fund may result in the Fund's being subject to covenants in credit agreements, including those relating to asset coverage and portfolio composition requirements. The Fund's lenders may establish guidelines for borrowing which may impose asset coverage or portfolio composition requirements that are more stringent than those imposed by the Investment Company Act. It is not anticipated that these covenants or guidelines will impede Credit Suisse in managing the Fund's portfolio in accordance with the Fund's investment objectives and policies.

Note 5. Purchases and Sales of Securities

For the six months ended April 30, 2007, purchases and sales of investment securities (excluding short-term investments) were $92,162,639 and $91,746,490, respectively.

At April 30, 2007, 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 $415,083,307, $16,270,854, $(7,055,957) and $9,214,897, respectively.

Note 6. Fund Shares

The Fund has one class of shares of beneficial interest, par value $0.001 per share; an unlimited number of shares are authorized. Transactions in shares of beneficial interest were as follows:

				For the Six Months Ended April 30, 2007 (unaudited)				For the Year Ended October 31, 2006
Shares issued through reinvestment of dividends					252,475				570,527

Note 7. Concentration of Risk

The Fund invests in securities offering high current income, which generally will be in the lower rating categories of recognized ratings agencies (commonly known as "junk bonds").

These securities generally involve more credit risk than securities in the higher rating categories. In addition, the trading market for high yield securities may be relatively less liquid than the market for higher-rated securities. The Fund's use of leverage also increases exposure to capital risk.

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.

Note 9. Recent Accounting Pronouncements

During June 2006, the Financial Accounting Standards Board ("FASB") issued FASB Interpretation 48 ("FIN 48" or the "Interpretation"), Accounting for Uncertainty in Income Taxes — an interpretation of FASB statement 109. FIN 48 supplements FASB Statement 109, Accounting for Income Taxes, by defining the confidence level that a tax position must meet in order to be recognized in the financial statements. FIN 48 prescribes a comprehensive model for how a fund should recognize, measure, present, and disclose in its financial statements uncertain tax positions that the fund has taken or expects to take on a tax return. FIN 48 requires that the tax effects of a position be recognized only if it is "more likely than not" to be sustained based solely on its technical merits. Management must be able to conclude that the tax law, regulations, case law, and other objective information regarding the technical merits sufficiently support the position's sustainability with a likelihood of more than 50 percent. FIN 48 is effective for fiscal periods beginning after December 15, 2006. At adoption, the financial statements must be adjusted to reflect only those tax positions that are more likely than not to be sustained as of the adoption date.

On September 20, 2006, the FASB released Statement of Financial Accounting Standards No. 157 "Fair Value Measurements" ("FAS 157"). FAS 157 establishes an authoritative definition of fair value, sets out a framework for measuring fair value, and requires additional disclosures about fair-value measurements. The application of FAS 157 is required for fiscal years, beginning after November 15, 2007 and interim periods within those fiscal years.

At this time, management is evaluating the implications of FIN 48 and FAS 157 and their impact on the financial statements has not yet been determined.

Credit Suisse High Yield Bond Fund

Board Consideration and Re-Approval of Investment Advisory Agreement (unaudited)

Section 15(c) of the Investment Company Act of 1940 (the "1940 Act") contemplates that the Board of Trustees (the "Board") of Credit Suisse High Yield Bond Fund (the "Fund"), including a majority of the Trustees who have no direct or indirect interest in the investment advisory agreement and are not "interested persons" of the Fund, as defined in the 1940 Act (the "Independent Trustees"), are required to annually review and re-approve the terms of the Fund's existing investment advisory agreement and approve any newly proposed terms therein. In this regard, the Board reviewed and re-approved, during the six months covered by this report an investment advisory agreement (the "Advisory Agreement") with Credit Suisse Asset Management, LLC ("Credit Suisse") for the Fund.

More specifically, at a meeting held on November 16, 2006, the Board, including the Independent Trustees advised by their independent legal counsel, considered the factors and reached the conclusions described below relating to the selection of Credit Suisse and the re-approval of the Advisory Agreement.

Nature, Extent and Quality of Services

The Board received and considered various data and information regarding the nature, extent and quality of services provided to the Fund by Credit Suisse under the Advisory Agreement. The most recent investment adviser registration form ("Form ADV") for Credit Suisse was provided to the Board, as were responses of Credit Suisse to requests submitted by the Independent Trustees' independent legal counsel on behalf of such Trustees. The Board reviewed and analyzed these materials, which included, among other things, information about the background and experience of the senior management and the expertise of investment personnel of Credit Suisse. In this regard, the Board specifically reviewed the qualifications, background and responsibilities of the individuals primarily responsible for day-to-day portfolio management services for the Fund. The Board also considered the organizational realignment of Credit Suisse's asset management business and the potential impact of such changes on the Fund.

In addition, the Board considered the investment and legal compliance programs of the Fund and Credit Suisse, including their compliance policies and procedures and reports of the Fund's Chief Compliance Officer.

The Board evaluated the ability of Credit Suisse, based on its resources, reputation and other attributes, to attract and retain qualified investment professionals, including research, advisory, and supervisory personnel. In this connection, the Board considered information regarding Credit Suisse's compensation arrangements for its personnel involved in the management of the Fund including incentive and retirement plans.

Based on the above factors, together with those referenced below, the Board concluded that it was satisfied with the nature, extent and quality of the investment advisory services provided to the Fund by Credit Suisse.

Fund Performance and Expenses

The Board considered performance results of the Fund over a number of years, as well as for recent periods. It also considered these results in comparison to the group of funds consisting of all closed-end leveraged high current yield funds (the "Performance Universe"), as well as for the Fund's benchmark index, the Merrill Lynch U.S. High Yield Master II Constrained Index. Lipper Inc. ("Lipper"), an independent provider of investment company data, determined the Performance Universe for the Fund and provided the comparative data. The Board was provided with a description of the methodology used by Lipper to select the closed-end funds in the Fund's Performance Universe. The Board noted that the Fund had underperformed the median performance of the funds in its Performance Universe in some periods, including the most recent period. However, the Board noted that the Fund outperformed the median performance of its Performance Universe in other periods.

Board Consideration and Re-Approval of Investment Advisory Agreement (unaudited) (continued)

The Board received and considered statistical information regarding the Fund's total expense ratio and its various components, including management fees, non-management fees and actual total expenses of the Fund (including and excluding investment-related expenses and taxes). It also considered comparisons of these fees to the expense information for the group of funds that was determined to be the most similar to the Fund (the "Peer Group") and to the median expenses of a broader universe of relevant funds (the "Expense Universe"), which comparative data was provided by Lipper. The Board was provided with a description of the methodology used by Lipper to select the closed-end funds in the Fund's Peer Group and Expense Universe.

The Board noted that the total expense ratio of the Fund is not appreciably higher than the median total expense ratio of the Fund's Peer Group including investment- related expenses and taxes. However, the Board noted that the Fund's actual non-management expenses were below the median of its Peer Group and Expense Universe.

Based on the above-referenced considerations and other factors, the Board concluded that the overall performance and expense results supported the re-approval of the Advisory Agreement for the Fund.

Investment Advisory Fee Rate

The Board reviewed and considered the proposed contractual investment advisory fee rate (the "Advisory Agreement Rate") payable by the Fund to Credit Suisse for investment advisory services.

Additionally, the Board received and considered information comparing the Advisory Agreement Rate (both on a stand-alone basis and on a combined basis with the Fund's administration fee rate) with those of the other funds in its Peer Group and Expense Universe. The Board noted that the Fund's administrator is not affiliated with Credit Suisse and that the Fund's administration agreement and corresponding fees were negotiated at arm's length. In this regard, the Board observed that the Advisory Agreement Rate was appreciably higher than the median rate of funds in its Peer Group. The Board asked that Credit Suisse review the Advisory Agreement Rate and consider lowering the rate in the future and Credit Suisse agreed to do so. As described in Note 3, above, in response to this request, Credit Suisse agreed effective January 1, 2007, to waive 0.15% of the fee payable under the Advisory Agreement. The Board also took note of the limited number of peer closed-end leveraged high current yield funds and the consequent small size of the Fund's Peer Group and Performance and Expense Universes.

Profitability

The Board received and considered an estimated profitability analysis of Credit Suisse based on the Advisory Agreement Rate, as well as on other relationships between the Fund and Credit Suisse and its affiliates. The Board concluded that, in light of the costs of providing investment management and other services to the Fund, the profits and other ancillary benefits that Credit Suisse and its affiliates received with regard to providing these services to the Fund were not unreasonable.

Economies of Scale

The Board received and considered information regarding whether there have been economies of scale with respect to the management of the Fund, whether the Fund has appropriately benefited from any economies of scale, and whether there is potential for realization of any further economies of scale. The Board concluded that any actual or potential economies of scale are shared fairly with Fund shareholders, including most particularly through Advisory Agreement Rate breakpoints.

The Board observed that the Advisory Agreement did not initially offer breakpoints. However, the Board noted that as part of its past review and re-approval of the Advisory Agreements it had approved the inclusion of breakpoints in the Advisory Agreement Rate and, as a result, there would be potential for Fund shareholders sharing in potential economies of scale.

Information about Services to Other Clients

The Board received and considered information about the nature and extent of services and fee rates offered by Credit Suisse to other clients, including other registered investment companies, separate accounts and institutional investors and investment companies to which Credit Suisse serves as an unaffiliated sub-adviser. The Board concluded that the Advisory Agreement Rate was reasonable given the nature and extent of services provided and comparison with fee rates offered to other clients. In this regard, where rates offered to other clients are appreciably lower, the Board concluded, based on information provided by Credit Suisse, that the costs associated with managing and operating a registered, closed-end, leveraged high yield bond fund, compared with other clients and other funds, provided a justification for the higher fee rates charged to the Fund.

Other Benefits to Credit Suisse

The Board received and considered information regarding potential "fall-out" or ancillary benefits received by Credit Suisse and its affiliates as a result of their relationship with the Fund. Such benefits could include, among others, benefits directly attributable to the relationship of Credit Suisse with the Fund and benefits potentially derived from an increase in the business of Credit Suisse as a result of their relationship with the Fund (such as the ability to market to shareholders other financial products offered by Credit Suisse and its affiliates).

Other Factors and Broader Review

As discussed above, the Board reviews detailed materials received from Credit Suisse annually as part of the re-approval process under Section 15(c) of the 1940 Act. The Board also reviews and assesses the quality of the services that the Fund receives throughout the year. In this regard, the Board reviews reports of Credit Suisse at least in each of its quarterly meetings, which include, among other things, a detailed portfolio review, and detailed fund performance reports, and confers with the chief investment officer of the Fund at various times throughout the year.

After considering the above-described factors and based on its deliberations and its evaluation of the information provided to it, the Board concluded that re-approval of the Advisory Agreement for the Fund was in the best interest of the Fund and its shareholders. Accordingly, the Board unanimously re-approved the Advisory Agreement.
