IMPORTANT NOTICES REGARDING PRIVACY,
DELIVERY OF SHAREHOLDER DOCUMENTS,
PORTFOLIO HOLDINGS AND PROXY VOTING

Privacy. The Eaton Vance organization is committed to ensuring your financial privacy. Each of the financial institutions identified below has in effect the following policy (“Privacy Policy”) with respect to nonpublic personal information about its customers:


	•	Only such information received from you, through application forms or otherwise, and information about your Eaton Vance fund transactions will be collected. This may include information such as name, address, social security number, tax status, account balances and transactions.

	•	None of such information about you (or former customers) will be disclosed to anyone, except as permitted by law (which includes disclosure to employees necessary to service your account). In the normal course of servicing a customer’s account, Eaton Vance may share information with unaffiliated third parties that perform various required services such as transfer agents, custodians and broker/dealers.

	•	Policies and procedures (including physical, electronic and procedural safeguards) are in place that are designed to protect the confidentiality of such information.

	•	We reserve the right to change our Privacy Policy at any time upon proper notification to you. Customers may want to review our Privacy Policy periodically for changes by accessing the link on our homepage: www.eatonvance.com.

Our pledge of privacy applies to the following entities within the Eaton Vance organization: the Eaton Vance Family of Funds, Eaton Vance Management, Eaton Vance Investment Counsel, Boston Management and Research, and Eaton Vance Distributors, Inc.

In addition, our Privacy Policy applies only to those Eaton Vance customers who are individuals and who have a direct relationship with us. If a customer’s account (i.e., fund shares) is held in the name of a third-party financial adviser/broker-dealer, it is likely that only such adviser’s privacy policies apply to the customer. This notice supersedes all previously issued privacy disclosures.

For more information about Eaton Vance’s Privacy Policy, please call 1-800-262-1122.

Delivery of Shareholder Documents. The Securities and Exchange Commission (the “SEC”) permits funds to deliver only one copy of shareholder documents, including prospectuses, proxy statements and shareholder reports, to fund investors with multiple accounts at the same residential or post office box address. This practice is often called “householding” and it helps eliminate duplicate mailings to shareholders.

Eaton Vance, or your financial adviser, may household the mailing of your documents indefinitely unless you instruct Eaton Vance, or your financial adviser, otherwise.

If you would prefer that your Eaton Vance documents not be householded, please contact Eaton Vance at 1-800-262-1122, or contact your financial adviser.

Your instructions that householding not apply to delivery of your Eaton Vance documents will be effective within 30 days of receipt by Eaton Vance or your financial adviser.

Portfolio Holdings. Each Eaton Vance Fund and its underlying Portfolio(s) (if applicable) will file a schedule of portfolio holdings on Form N-Q with the SEC for the first and third quarters of each fiscal year. The Form N-Q will be available on the Eaton Vance website at www.eatonvance.com, by calling Eaton Vance at 1-800-262-1122 or in the EDGAR database on the SEC’s website at www.sec.gov. Form N-Q may also be reviewed and copied at the SEC’s public reference room in Washington, D.C. (call 1-800-732-0330 for information on the operation of the public reference room).

Proxy Voting. From time to time, funds are required to vote proxies related to the securities held by the funds. The Eaton Vance Funds or their underlying Portfolios (if applicable) vote proxies according to a set of policies and procedures approved by the Funds’ and Portfolios’ Boards. You may obtain a description of these policies and procedures and information on how the Funds or Portfolios voted proxies relating to portfolio securities during the most recent 12 month period ended June 30, without charge, upon request, by calling 1-800-262-1122. This description is also available on the SEC’s website at www.sec.gov.

Economic and Market Conditions

•		The six months ending October 31, 2009, were marked by a worldwide rally across the spectrum of riskier assets. The pace of economic deterioration slowed and then rebounded slightly in these six months, compared to the free-fall in world economic output witnessed at the end of 2008 and first quarter of 2009. As signs of improving economic fundamentals began to emerge, investors’ aversion to risk reversed course and the capital markets staged a comeback.

•		The loan market, as measured by the S&P/LSTA Leveraged Loan Index (the Index), gained 23.08% for the six months ending October 31, 2009, one of the highest six-month returns in the history of the asset class. ¹ Performance was driven by a combination of technical factors, which improved the market’s supply and demand picture. On the supply side, limited new loan issuance and a contraction of the existing supply through loan repayments reduced the available universe of purchasable loans. On the demand side, little selling activity and modest but steady inflows helped loan prices improve significantly. Modest improvements in loan fundamentals, or a deceleration of credit deterioration in many cases, also contributed to the increase in prices during the period. The default rate for the S&P/LSTA Leveraged Loan Index reached 12.0% as of October 31, 2009—near historical post-recession peaks.

•

The high-yield market also had strong performance during 2009. The BofA Merrill Lynch U.S. High Yield Index returned 29.16% during the six months ending October 31, 2009. ¹ High-yield spreads—the additional yield over U.S. Treasury bonds of comparable maturity—narrowed significantly, from 1,330 basis points (13.3%) as of April 30, 2009, to 760 basis points (7.6%) as of October 31, 2009. Lower-quality paper led performance during the period, with CCC-rated issues performing the best, followed by BB-rated and B-rated bonds. The new-issue market remained strong, with the year-to-date total at almost $110 billion in new issues, roughly three times the amount of issuance during the first nine months of 2008. Defaults continued to increase, as Moody’s Investors Service reported speculative-grade defaults hitting 12.4% at the end of October 2009. This compares closely with historical peaks in past recessions of 11.01% in January 2002 and 12.07% in mid-1991.

Past performance is no guarantee of future results. Returns are historical and are calculated by determining the percentage change in net asset value or market price (as applicable) with all distributions reinvested. The Fund’s performance at market price will differ from its results at NAV. Although market price performance generally reflects investment results over time, during shorter periods, returns at market price can also be affected by factors such as changing perceptions about the Fund, market conditions, fluctuations in supply and demand for the Fund’s shares, or changes in Fund distributions. Investment return and principal value will fluctuate so that shares, when sold, may be worth more or less than their original cost. Performance is for the stated time period only; due to market volatility, the Fund’s current performance may be lower or higher than the quoted return. For performance as of the most recent month end, please refer to www.eatonvance.com.

Management Discussion

• The Fund is a closed-end fund and trades on the New York Stock Exchange under the symbol “EOE.” The Fund’s investment objective is to provide a high level of current income, with a secondary objective of capital appreciation.

• The Fund’s loan investments are well diversified, with 105 borrowers and no single investment representing more than 2.4% of the total investments. The Fund is also broadly

¹		It is not possible to invest directly in an Index. The Index’s total return reflects changes in value of the loans constituting the Index and accrual of interest and does not reflect the commissions or expenses that would have been incurred if an investor individually purchased or sold the loans represented in the Index. Unlike the Fund, the Index’s return does not reflect the effect of leverage.

²		Performance results reflect the effects of leverage.

³		The Distribution Rate is based on the Fund’s last regular distribution per share (annualized) divided by the Fund’s NAV or market price at the end of the period. The Fund’s distributions may be comprised of ordinary income, net realized capital gains and return of capital.

Fund shares are not insured by the FDIC and are not deposits or other obligations of, or guaranteed by, any depository institution. Shares are subject to investment risks, including possible loss of principal invested.

INVESTMENT UPDATE

		diversified by industry, as none constituted more than 10.2% of total investments as of October 31, 2009. A diversified approach should help the Fund mitigate risk in an increasing default environment. Management can shift allocations among loans and bonds. The Fund remained more-heavily weighted toward first and second lien secured loans, which, in management’s view, may fare better in an increasing default environment.

•		Although the general loan and high-yield markets rallied strongly over the past six months, the Fund still outpaced the Index by a significant margin. The Fund experienced strong total returns over the past six months of 67.55% at market price and 65.16% at NAV. The Fund was heavily weighted in the lower range of the credit spectrum at the onset of the credit markets recovery. These lower-rated loans and securities led the market and made the largest contribution to the Fund’s outperformance of the Index for the period. The Fund also employed modest leverage, which enhanced returns as the market rose.

•		The Fund’s high-yield bond investments benefited from a bias toward B-rated issues and an overweight to CCC-rated issues. Remaining fully invested throughout this market cycle was also beneficial. Company selection within the paper and retail industries, coupled with modest overweight positions to each, contributed positively to portfolio returns during the period. A broad underweight to the utilities sector also helped relative performance during the period. The Fund’s lagging sectors were banking and diversified financial services.

•		As of October 31, 2009, the Fund had outstanding leverage of approximately 10.2% of its total assets. That leverage consists of Auction Preferred Shares (APS) issued by the Fund. ¹ Use of leverage creates an opportunity for income, but also creates special risks (including the likelihood of greater volatility of net asset value and market price of common shares).

•		At a special meeting of shareholders of the Fund expected to be held on January 22, 2010, shareholders of the Fund will be asked to approve an Agreement and Plan of Reorganization that will merge the Fund into Eaton Vance Limited Duration Income Fund (Limited Duration Income Fund). Under the terms of the Agreement and Plan of Reorganization, Limited Duration Income Fund would acquire substantially all the assets and assume substantially all the liabilities of the Fund in exchange for common shares of the Limited Duration Income Fund and cash consideration equal to the aggregate liquidation value of the Fund’s APS. Proxy materials containing information about the meeting and the proposed transaction will be mailed to the Fund’s common shareholders of record as of November 12, 2009. The Board of Trustees recommends that the shareholders of the Fund vote for the proposed merger.

The views expressed throughout this report are those of the portfolio managers and are current only through the end of the period of the report as stated on the cover. These views are subject to change at any time based upon market or other conditions, and the investment adviser disclaims any responsibility to update such views. These views may not be relied on as investment advice and, because investment decisions for a fund are based on many factors, may not be relied on as an indication of trading intent on behalf of any Eaton Vance fund. Portfolio information provided in the report may not be representative of the Fund’s current or future investments and may change due to active management.


¹		APS percentage represents the liquidation value of the Fund’s APS outstanding at 10/31/09 as a percentage of the Fund’s net assets applicable to common shares plus APS. In the event of a rise in long-term interest rates, the value of the Fund’s investment portfolio could decline, which would reduce the asset coverage for its APS.

Although the investment adviser considers ratings when making investment decisions, it performs its own credit and investment analysis and does not rely primarily on the ratings assigned by the rating services. Credit quality can change from time to time, and recently issued credit ratings may not fully reflect the actual risks posed by a particular security or the issuer’s current financial condition. The rating assigned to a security by a rating agency does not necessarily reflect its assessment of the volatility of a security’s market value or of the liquidity of an investment in the security.

⁵		Certain loans in which the Fund invests are not rated by a rating agency. In management’s opinion, such securities are comparable to securities rated by a rating agency in the categories listed above.

(1)		Senior floating-rate interests (Senior Loans) often require prepayments from excess cash flows or permit the borrowers to repay at their election. The degree to which borrowers repay, whether as a contractual requirement or at their election, cannot be predicted with accuracy. As a result, the actual remaining maturity may be substantially less than the stated maturities shown. However, Senior Loans will have an expected average life of approximately two to four years. The stated interest rate represents the weighted average interest rate of all contracts within the senior loan facility and includes commitment fees on unfunded loan commitments, if any. Senior Loans typically have rates of interest which are redetermined either daily, monthly, quarterly or semi-annually by reference to a base lending rate, plus a premium. These base rates are primarily the London Interbank Offered Rate (“LIBOR”) and secondarily, the prime rate offered by one or more major United States banks (the “Prime Rate”) and the certificate of deposit (“CD”) rate or other base lending rates used by commercial lenders.

(2)		Currently the issuer is in default with respect to interest payments.

(3)		Represents a payment-in-kind security which may pay all or a portion of interest/dividends in additional par/shares.

(4)		Defaulted matured security.

(5)		This Senior Loan will settle after October 31, 2009, at which time the interest rate will be determined.

(6)		Unfunded or partially unfunded loan commitments. See Note 1G for description.

(7)		Security valued at fair value using methods determined in good faith by or at the direction of the Trustees.

NOTES TO FINANCIAL STATEMENTS (Unaudited)

1 Significant Accounting Policies

Eaton Vance Credit Opportunities Fund (the Fund) is a Massachusetts business trust registered under the Investment Company Act of 1940, as amended (the 1940 Act), as a diversified, closed-end management investment company. The Fund’s primary investment objective is to provide a high level of current income. The Fund, as a secondary objective, also seeks capital appreciation.

The following is a summary of significant accounting policies of the Fund. The policies are in conformity with accounting principles generally accepted in the United States of America. A source of authoritative accounting principles applied in the preparation of the Fund’s financial statements is the Financial Accounting Standards Board (FASB) Accounting Standards Codification (the Codification), which superseded existing non-Securities and Exchange Commission accounting and reporting standards for interim and annual reporting periods ending after September 15, 2009. The adoption of the Codification for the current reporting period did not impact the Fund’s application of generally accepted accounting principles.

A Investment Valuation — Interests in senior floating-rate loans (Senior Loans) for which reliable market quotations are readily available are valued generally at the average mean of bid and ask quotations obtained from a third party pricing service. Other Senior Loans are valued at fair value by the investment adviser under procedures approved by the Trustees. In fair valuing a Senior Loan, the investment adviser utilizes one or more of the valuation techniques described in (i) through (iii) below to assess the likelihood that the borrower will make a full repayment of the loan underlying such Senior Loan relative to yields on other Senior Loans issued by companies of comparable credit quality. If the investment adviser believes that there is a reasonable likelihood of full repayment, the investment adviser will determine fair value using a matrix pricing approach that considers the yield on the Senior Loan. If the investment adviser believes there is not a reasonable likelihood of full repayment, the investment adviser will determine fair value using analyses that include, but are not limited to: (i) a comparison of the value of the borrower’s outstanding equity and debt to that of comparable public companies; (ii) a discounted cash flow analysis; or (iii) when the investment adviser believes it is likely that a borrower will be liquidated or sold, an analysis of the terms of such liquidation or sale. In certain cases, the investment adviser will use a combination of analytical methods to determine fair value, such as when only a portion of a borrower’s assets are likely to be sold. In conducting its assessment and analyses for purposes of determining fair value of a Senior Loan, the investment adviser will use its discretion and judgment in considering and appraising relevant factors. Fair value determinations are made by the portfolio managers of the Fund based on information available to such managers. The portfolio managers of other funds managed by the investment adviser that invest in Senior Loans may not possess the same information about a Senior Loan borrower as the portfolio managers of the Fund. At times, the fair value of a Senior Loan determined by the portfolio managers of other funds managed by the investment adviser that invest in Senior Loans may vary from the fair value of the same Senior Loan determined by the portfolio managers of the Fund. The fair value of each Senior Loan is periodically reviewed and approved by the investment adviser’s Valuation Committee and by the Trustees based upon procedures approved by the Trustees. Junior Loans are valued in the same manner as Senior Loans.

Debt obligations (including short-term obligations with a remaining maturity of more than sixty days) will normally be valued on the basis of quotations provided by third party pricing services. The pricing services will use various techniques that consider factors including, but not limited to, reported trades or dealer quotations, prices or yields of securities with similar characteristics, benchmark yields, broker/dealer quotes, issuer spreads, as well as industry and economic events. Short-term debt securities with a remaining maturity of sixty days or less are generally valued at amortized cost, which approximates market value. Equity securities (including common shares of closed-end investment companies) listed on a U.S. securities exchange generally are valued at the last sale price on the day of valuation or, if no sales took place on such date, at the mean between the closing bid and asked prices therefore on the exchange where such securities are principally traded. Equity securities listed on the NASDAQ Global or Global Select Market generally are valued at the NASDAQ official closing price. Unlisted or listed securities for which closing sales prices or closing quotations are not available are valued at the mean between the latest available bid and asked prices or, in the case of preferred equity securities that are not listed or traded in the over-the-counter market, by a third party pricing service that will use various techniques that consider factors including, but not limited to, prices or yields of securities with similar characteristics, benchmark yields, broker/dealer quotes, quotes of underlying common stock, issuer spreads, as well as industry and economic events. Forward foreign currency exchange contracts are generally valued at the mean of the average bid and average asked prices that are reported by currency dealers to a third party pricing service at the valuation time. Such third party pricing service valuations are supplied for specific settlement periods and the Fund’s forward foreign currency exchange contracts are valued at an interpolated rate between the closest preceding and subsequent settlement period reported by the third party pricing service. Interest rate swaps and floors are normally valued using valuations provided by a third party pricing service. Such pricing service valuations are based on the present value of fixed and projected floating rate cash flows over the term of the

Eaton Vance Credit Opportunities Fund as of October 31, 2009

NOTES TO FINANCIAL STATEMENTS (Unaudited) CONT’D

swap contract. Future cash flows are discounted to their present value using swap quotations provided by electronic data services or by broker/dealers. Foreign securities and currencies are valued in U.S. dollars, based on foreign currency exchange rate quotations supplied by a third party pricing service. The pricing service uses a proprietary model to determine the exchange rate. Inputs to the model include reported trades and implied bid/ask spreads. Investments for which valuations or market quotations are not readily available or are deemed unreliable are valued at fair value using methods determined in good faith by or at the direction of the Trustees of the Fund in a manner that most fairly reflects the security’s value, or the amount that the Fund might reasonably expect to receive for the security upon its current sale in the ordinary course. Each such determination is based on a consideration of all relevant factors, which are likely to vary from one pricing context to another. These factors may include, but are not limited to, the type of security, the existence of any contractual restrictions on the security’s disposition, the price and extent of public trading in similar securities of the issuer or of comparable companies or entities, quotations or relevant information obtained from broker-dealers or other market participants, information obtained from the issuer, analysts, and/or the appropriate stock exchange (for exchange-traded securities), an analysis of the company’s or entity’s financial condition, and an evaluation of the forces that influence the issuer and the market(s) in which the security is purchased and sold.

The Fund may invest in Cash Management Portfolio (Cash Management), an affiliated investment company managed by Boston Management and Research (BMR), a subsidiary of Eaton Vance Management (EVM). Cash Management generally values its investment securities utilizing the amortized cost valuation technique permitted by Rule 2a-7 of the 1940 Act, pursuant to which Cash Management must comply with certain conditions. This technique involves initially valuing a portfolio security at its cost and thereafter assuming a constant amortization to maturity of any discount or premium. If amortized cost is determined not to approximate fair value, Cash Management may value its investment securities in the same manner as debt obligations described above.

B Investment Transactions — Investment transactions for financial statement purposes are accounted for on a trade date basis. Realized gains and losses on investments sold are determined on the basis of identified cost.

C Income — Interest income is recorded on the basis of interest accrued, adjusted for amortization of premium or accretion of discount. Fees associated with loan amendments are recognized immediately. Dividend income is recorded on the ex-dividend date for dividends received in cash and/or securities.

D Federal Taxes — The Fund’s policy is to comply with the provisions of the Internal Revenue Code applicable to regulated investment companies and to distribute to shareholders each year substantially all of its net investment income, and all or substantially all of its net realized capital gains. Accordingly, no provision for federal income or excise tax is necessary.

At April 30, 2009, the Fund, for federal income tax purposes, had a capital loss carryforward of $29,535,416 which will reduce its taxable income arising from future net realized gains on investment transactions, if any, to the extent permitted by the Internal Revenue Code, and thus will reduce the amount of distributions to shareholders, which would otherwise be necessary to relieve the Fund of any liability for federal income or excise tax. Such capital loss carryforward will expire on April 30, 2016 ($833,774) and April 30, 2017 ($28,701,642).

Additionally, at April 30, 2009, the Fund had a net currency loss of $3,182,743 and a net capital loss of $10,128,221 attributable to foreign currency and security transactions, respectively, incurred after October 31, 2008. These losses are treated as arising on the first day of the Fund’s taxable year ending April 30, 2010.

As of October 31, 2009, the Fund had no uncertain tax positions that would require financial statement recognition, de-recognition, or disclosure. Each of the Fund’s federal tax returns filed since the start of business on May 31, 2006 to April 30, 2009 remains subject to examination by the Internal Revenue Service.

E Expense Reduction — State Street Bank and Trust Company (SSBT) serves as custodian of the Fund. Pursuant to the custodian agreement, SSBT receives a fee reduced by credits, which are determined based on the average daily cash balance the Fund maintains with SSBT. All credit balances, if any, used to reduce the Fund’s custodian fees are reported as a reduction of expenses in the Statement of Operations.

F Foreign Currency Translation — Investment valuations, other assets, and liabilities initially expressed in foreign currencies are translated each business day into U.S. dollars based upon current exchange rates. Purchases and sales of foreign investment securities and income and expenses denominated in foreign currencies are translated into U.S. dollars based upon currency exchange rates in effect on the respective dates of such transactions. Recognized gains or losses on investment transactions attributable to changes in foreign currency exchange rates are recorded for financial statement purposes as net realized gains and losses on investments. That portion of unrealized gains and losses on investments that results from fluctuations in foreign currency exchange rates is not separately disclosed.

G Unfunded Loan Commitments — The Fund may enter into certain credit agreements all or a portion of which may be unfunded. The Fund is obligated to fund these commitments at the borrower’s discretion. The commitments are disclosed in the accompanying Portfolio of Investments.

H Use of Estimates — The preparation of the financial statements in conformity with accounting principles generally accepted in the United States of America requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities at the date of the financial statements and the reported amounts of income and expense during the reporting period. Actual results could differ from those estimates.

I Indemnifications — Under the Fund’s organizational documents, its officers and Trustees may be indemnified against certain liabilities and expenses arising out of the performance of their duties to the Fund, and shareholders are indemnified against personal liability for the obligations of the Fund. Additionally, in the normal course of business, the Fund enters into agreements with service providers that may contain indemnification clauses. The Fund’s maximum exposure under these arrangements is unknown as this would involve future claims that may be made against the Fund that have not yet occurred.

J Forward Foreign Currency Exchange Contracts — The Fund may enter into forward foreign currency exchange contracts for the purchase or sale of a specific foreign currency at a fixed price on a future date. The Fund may enter into forward contracts for hedging purposes as well as non-hedging purposes. The forward foreign currency exchange contracts are adjusted by the daily exchange rate of the underlying currency and any gains or losses are recorded as unrealized until such time as the contracts have been closed or offset by another contract with the same broker for the same settlement date and currency. Risks may arise upon entering these contracts from the potential inability of counterparties to meet the terms of their contracts and from movements in the value of a foreign currency relative to the U.S. dollar.

K Interest Rate Floors — The Fund may enter into interest rate floors to enhance return or to hedge against fluctuations in interest rates. Interest rate floors are similar to interest rate swaps, except that one party agrees to pay a fee, while the other party agrees to make payments to the extent that interest rates fall below a specified rate or “floor”. Transaction fees paid by the Fund are recognized as assets and amortized over the life of the interest rate floor. Changes in the value of the interest rate floor are recognized as unrealized gains and losses.

L Interim Financial Statements — The interim financial statements relating to October 31, 2009 and for the six months then ended have not been audited by an independent registered public accounting firm, but in the opinion of the Fund’s management, reflect all adjustments, consisting only of normal recurring adjustments, necessary for the fair presentation of the financial statements.

2 Auction Preferred Shares

The Fund issued Auction Preferred Shares (APS) on August 11, 2006 in a public offering. The underwriting discount and other offering costs incurred in connection with the offering were recorded as a reduction of the paid-in capital of the common shares. Dividends on the APS, which accrue daily, are cumulative at rates which are reset every seven days by an auction, unless a special dividend period has been set. If the APS auctions do not successfully clear, the dividend payment rate over the next period for the APS holders is set at a specified maximum applicable rate until such time as the APS auctions are successful. Auctions have not cleared since February 13, 2008 and the rate since that date has been the maximum applicable rate (see Note 3). The maximum applicable rate on the APS is the greater of 1) 150% of LIBOR at the date of the auction or 2) LIBOR at the date of the auction plus 1.50%.

During the six months ended October 31, 2009, the Fund made a partial redemption of its APS at a liquidation price of $25,000 per share. The number of APS redeemed and redemption amount (excluding the final dividend payment) during the six months ended October 31, 2009 and the number of APS issued and outstanding as of October 31, 2009 are as follows:


APS Redeemed
During the	Redemption		APS Issued and
Period	Amount		Outstanding

763	$	19,075,000	320

The APS are redeemable at the option of the Fund at a redemption price equal to $25,000 per share, plus accumulated and unpaid dividends, on any dividend payment date. The APS are also subject to mandatory redemption at a redemption price equal to $25,000 per share, plus accumulated and unpaid dividends, if the Fund is in default for an extended period on its asset maintenance requirements with respect to the APS. If the dividends on the APS remain unpaid in an amount equal to two full years’ dividends, the holders of the APS as a class have the right to elect a majority of the Board of Trustees. In general, the holders of the APS and the common shares have equal voting rights of one vote per share, except that the holders of the APS, as a separate class, have the right to elect at least two members of the Board of Trustees. The APS have a liquidation preference of $25,000 per share, plus accumulated and unpaid dividends. The Fund is required to maintain certain asset

Eaton Vance Credit Opportunities Fund as of October 31, 2009

NOTES TO FINANCIAL STATEMENTS (Unaudited) CONT’D

coverage with respect to the APS as defined in the Fund’s By-Laws and the 1940 Act. The Fund pays an annual fee up to 0.15% (0.25% prior to March 2009) of the liquidation value of the APS to broker-dealers as a service fee if the auctions are unsuccessful; otherwise, the annual fee is 0.25%.

3 Distributions to Shareholders

The Fund intends to make monthly distributions of net investment income to common shareholders, after payment of any dividends on any outstanding APS. In addition, at least annually, the Fund intends to distribute all or substantially all of its net realized capital gains, (reduced by available capital loss carryforwards from prior years, if any). Distributions to common shareholders are recorded on the ex-dividend date. Distributions to preferred shareholders are recorded daily and are payable at the end of each dividend period. The dividend rate for the APS at October 31, 2009 was 1.72%. For the six months ended October 31, 2009, the amount of dividends paid (including capital gains, if any) to APS shareholders was $87,183, representing an average APS dividend rate of 1.77% (annualized) and dividend rate ranges of 1.72% to 1.83%.

Beginning February 13, 2008 and consistent with the patterns in the broader market for auction-rate securities, the Fund’s APS auctions were unsuccessful in clearing due to an imbalance of sell orders over bids to buy the APS. As a result, the dividend rates of the APS were reset to the maximum applicable rate. The rate above reflects such maximum dividend rate as of October 31, 2009.

The Fund distinguishes between distributions on a tax basis and a financial reporting basis. Accounting principles generally accepted in the United States of America require that only distributions in excess of tax basis earnings and profits be reported in the financial statements as a return of capital. Permanent differences between book and tax accounting relating to distributions are reclassified to paid-in capital. For tax purposes, distributions from short-term capital gains are considered to be from ordinary income.

4 Investment Adviser Fee and Other Transactions with Affiliates

The investment adviser fee is earned by EVM as compensation for management and investment advisory services rendered to the Fund. The fee is computed at an annual rate of 0.75% of the Fund’s average daily gross assets and is payable monthly. Gross assets as referred to herein represent net assets plus obligations attributable to investment leverage. The portion of the adviser fee payable by Cash Management on the Fund’s investment of cash therein is credited against the Fund’s adviser fee. For the six months ended October 31, 2009, the Fund’s investment adviser fee totaled $259,137 of which $9,914 was allocated from Cash Management and $249,223 was paid or accrued directly by the Fund. EVM also serves as administrator of the Fund, but receives no compensation.

In addition, EVM has contractually agreed to reimburse the Fund for fees and other expenses at an annual rate of 0.20% of the Fund’s average daily gross assets during the first five full years of the Fund’s operations, 0.15% of the Fund’s average daily gross assets in year six, 0.10% in year seven and 0.05% in year eight. Pursuant to this agreement, EVM waived $69,103 of its investment adviser fee for the six months ended October 31, 2009.

Except for Trustees of the Fund who are not members of EVM’s organization, officers and Trustees receive remuneration for their services to the Fund out of the investment adviser fee. Trustees of the Fund who are not affiliated with EVM may elect to defer receipt of all or a percentage of their annual fees in accordance with the terms of the Trustees Deferred Compensation Plan. For the six months ended October 31, 2009, no significant amounts have been deferred. Certain officers and Trustees of the Fund are officers of EVM.

5 Purchases and Sales of Investments

Purchases and sales of investments, other than short-term obligations and including maturities and principal repayments on Senior Loans, aggregated $9,878,158 and $12,415,481, respectively, for the six months ended October 31, 2009.

6 Common Shares of Beneficial Interest

The Fund may issue common shares pursuant to its dividend reinvestment plan. There were no transactions in common shares for the six months ended October 31, 2009. Common shares issued pursuant to the Fund’s dividend reinvestment plan for the year ended April 30, 2009 were 17,348.

7 Federal Income Tax Basis of Investments

The cost and unrealized appreciation (depreciation) of investments of the Fund at October 31, 2009, as determined on a federal income tax basis, were as follows:


Aggregate cost	$	107,836,474


Gross unrealized appreciation	$	395,494
Gross unrealized depreciation		(29,400,600	)


Net unrealized depreciation	$	(29,005,106	)

8 Restricted Securities

At October 31, 2009, the Fund owned the following securities (representing less than 0.1% of net assets applicable to common shares) which were restricted as to

NOTES TO FINANCIAL STATEMENTS (Unaudited) CONT’D

public resale and not registered under the Securities Act of 1933 (excluding Rule 144A securities). The Fund has various registration rights (exercisable under a variety of circumstances) with respect to these securities. The value of these securities is determined based on valuations provided by brokers when available, or if not available, they are valued at fair value using methods determined in good faith by or at the direction of the Trustees.

9 Financial Instruments

The Fund may trade in financial instruments with off-balance sheet risk in the normal course of its investing activities. These financial instruments may include forward foreign currency exchange contracts and may involve, to a varying degree, elements of risk in excess of the amounts recognized for financial statement purposes. The notional or contractual amounts of these instruments represent the investment the Fund has in particular classes of financial instruments and does not necessarily represent the amounts potentially subject to risk. The measurement of the risks associated with these instruments is meaningful only when all related and offsetting transactions are considered.

A summary of obligations under these financial instruments at October 31, 2009 is as follows:


Forward Foreign Currency Exchange Contracts

Sales

			Net Unrealized
Settlement			Appreciation
Date	Deliver	In Exchange For	(Depreciation)

11/30/09	British Pound Sterling 1,598,413	United States Dollar 2,612,047	$(10,887)
11/30/09	Euro 6,044,184	United States Dollar 8,927,562	33,177


			$22,290

At October 31, 2009, the Fund had sufficient cash and/or securities to cover commitments under these contracts.

The Fund adopted FASB Statement of Financial Accounting Standards No. 161 (FAS 161), “Disclosures about Derivative Instruments and Hedging Activities”, (currently FASB Accounting Standards Codification (ASC) 815-10), effective May 1, 2009. Such standard requires enhanced disclosures about an entity’s derivative and hedging activities, including qualitative disclosures about the objectives and strategies for using derivatives, quantitative disclosures about fair value amounts of and gains and losses on derivative instruments, and disclosures about credit-risk related contingent features in derivative instruments. The disclosure below includes additional information as a result of implementing FAS 161.

The Fund is subject to foreign exchange risk in the normal course of pursuing its investment objectives. Because the Fund holds foreign currency denominated investments, the value of these investments and related receivables and payables may change due to future changes in foreign currency exchange rates. To hedge against this risk, the Fund may enter into forward foreign currency exchange contracts. The Fund may also enter into such contracts to hedge currency risk of investments it anticipates purchasing.

The forward foreign currency exchange contracts in which the Fund invests are subject to the risk that the counterparty to the contract fails to perform its obligations under the contract. At October 31, 2009, the maximum amount of loss the Fund would incur due to counterparty risk was $33,177, representing the fair value of such derivatives in an asset position.

The fair value of derivative instruments (not considered to be hedging instruments for accounting disclosure purposes) and whose primary underlying risk exposure is foreign exchange risk at October 31, 2009 was as follows:


	Fair Value
Derivative	Asset Derivatives			Liability Derivatives

Forward foreign currency exchange contracts	$	33,177 ⁽¹	⁾	$	(10,887	) ⁽²⁾

(2)		Statement of Operations location: Change in unrealized appreciation (depreciation) — Foreign currency and forward foreign currency exchange contracts.

Eaton Vance Credit Opportunities Fund as of October 31, 2009

NOTES TO FINANCIAL STATEMENTS (Unaudited) CONT’D

The average notional amount of forward foreign currency exchange contracts outstanding during the six months ended October 31, 2009, which is indicative of the volume of this derivative type, was approximately $8,276,000.

10 Risks Associated with Foreign Investments

Investing in securities issued by companies whose principal business activities are outside the United States may involve significant risks not present in domestic investments. For example, there is generally less publicly available information about foreign companies, particularly those not subject to the disclosure and reporting requirements of the U.S. securities laws. Certain foreign issuers are generally not bound by uniform accounting, auditing, and financial reporting requirements and standards of practice comparable to those applicable to domestic issuers. Investments in foreign securities also involve the risk of possible adverse changes in investment or exchange control regulations, expropriation or confiscatory taxation, limitation on the removal of funds or other assets of the Fund, political or financial instability or diplomatic and other developments which could affect such investments. Foreign securities markets, while growing in volume and sophistication, are generally not as developed as those in the United States, and securities of some foreign issuers (particularly those located in developing countries) may be less liquid and more volatile than securities of comparable U.S. companies. In general, there is less overall governmental supervision and regulation of foreign securities markets, broker-dealers and issuers than in the United States.

11 Concentration of Credit Risk

The Fund invests primarily in below investment grade floating-rate loans and floating-rate debt obligations, which are considered speculative because of the credit risk of their issuers. Changes in economic conditions or other circumstances are more likely to reduce the capacity of issuers of these securities to make principal and interest payments. Such companies are more likely to default on their payments of interest and principal owed than issuers of investment grade bonds. An economic downturn generally leads to a higher non-payment rate, and a loan or other debt obligation may lose significant value before a default occurs. Lower rated investments also may be subject to greater price volatility than higher rated investments. Moreover, the specific collateral used to secure a loan may decline in value or become illiquid, which would adversely affect the loan’s value.

12 Fair Value Measurements

Under generally accepted accounting principles for fair value measurements, a three-tier hierarchy to prioritize the assumptions, referred to as inputs, is used in valuation techniques to measure fair value. The three-tier hierarchy of inputs is 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 a fund’s own assumptions in determining the fair value of investments)

The inputs or methodology used for valuing securities are not necessarily an indication of the risk associated with investing in those securities.

At October 31, 2009, the inputs used in valuing the Fund’s investments, which are carried at value, were as follows:


	Quoted
	Prices in
	Active		Significant
	Markets for		Other			Significant
	Identical		Observable			Unobservable

13 Proposed Plan of Reorganization

In June of 2009, the Trustees of the Fund approved an Agreement and Plan of Reorganization (the Agreement) whereby Eaton Vance Limited Duration Income Fund (the Acquiring Fund) would acquire substantially all the assets and assume substantially all the liabilities of the Fund in exchange for common shares of the Acquiring Fund and cash consideration equal to the aggregate liquidation value of the Fund’s APS. The proposed reorganization is subject to approval by the shareholders of the Fund.

14 Review for Subsequent Events

In connection with the preparation of the financial statements of the Fund as of and for the six months ended October 31, 2009, events and transactions subsequent to October 31, 2009 through December 15, 2009, the date the financial statements were issued, have been evaluated by the Fund’s management for possible adjustment and/or disclosure. Management has not identified any subsequent events requiring financial statement disclosure as of the date these financial statements were issued.

BOARD OF TRUSTEES’ ANNUAL APPROVAL OF THE INVESTMENT ADVISORY AGREEMENT

Overview of the Contract Review Process

The Investment Company Act of 1940, as amended (the “1940 Act”), provides, in substance, that each investment advisory agreement between a fund and its investment adviser will continue in effect from year to year only if its continuance is approved at least annually by the fund’s board of trustees, including by a vote of a majority of the trustees who are not “interested persons” of the fund (“Independent Trustees”), cast in person at a meeting called for the purpose of considering such approval.

At a meeting of the Boards of Trustees (each a “Board”) of the Eaton Vance group of mutual funds (the “Eaton Vance Funds”) held on April 27, 2009, the Board, including a majority of the Independent Trustees, voted to approve continuation of existing advisory and sub-advisory agreements for the Eaton Vance Funds for an additional one-year period. In voting its approval, the Board relied upon the affirmative recommendation of the Contract Review Committee of the Board (formerly the Special Committee), which is a committee comprised exclusively of Independent Trustees. Prior to making its recommendation, the Contract Review Committee reviewed information furnished for a series of meetings of the Contract Review Committee held in February, March and April 2009. Such information included, among other things, the following:

Information about Fees, Performance and Expenses


	•	An independent report comparing the advisory and related fees paid by each fund with fees paid by comparable funds;
	•	An independent report comparing each fund’s total expense ratio and its components to comparable funds;
	•	An independent report comparing the investment performance of each fund to the investment performance of comparable funds over various time periods;
	•	Data regarding investment performance in comparison to relevant peer groups of funds and appropriate indices;
	•	Comparative information concerning fees charged by each adviser for managing other mutual funds and institutional accounts using investment strategies and techniques similar to those used in managing the fund;
	•	Profitability analyses for each adviser with respect to each fund;

Information about Portfolio Management


	•	Descriptions of the investment management services provided to each fund, including the investment strategies and processes employed, and any changes in portfolio management processes and personnel;
	•	Information concerning the allocation of brokerage and the benefits received by each adviser as a result of brokerage allocation, including information concerning the acquisition of research through “soft dollar” benefits received in connection with the funds’ brokerage, and the implementation of a soft dollar reimbursement program established with respect to the funds;
	•	Data relating to portfolio turnover rates of each fund;
	•	The procedures and processes used to determine the fair value of fund assets and actions taken to monitor and test the effectiveness of such procedures and processes;

Information about each Adviser


	•	Reports detailing the financial results and condition of each adviser;
	•	Descriptions of the qualifications, education and experience of the individual investment professionals whose responsibilities include portfolio management and investment research for the funds, and information relating to their compensation and responsibilities with respect to managing other mutual funds and investment accounts;
	•	Copies of the Codes of Ethics of each adviser and its affiliates, together with information relating to compliance with and the administration of such codes;
	•	Copies of or descriptions of each adviser’s proxy voting policies and procedures;
	•	Information concerning the resources devoted to compliance efforts undertaken by each adviser and its affiliates on behalf of the funds (including descriptions of various compliance programs) and their record of compliance with investment policies and restrictions, including policies with respect to market-timing, late trading and selective portfolio disclosure, and with policies on personal securities transactions;
	•	Descriptions of the business continuity and disaster recovery plans of each adviser and its affiliates;

Eaton Vance Credit Opportunities Fund

BOARD OF TRUSTEES’ ANNUAL APPROVAL OF THE INVESTMENT ADVISORY AGREEMENT CONT’D

In addition to the information identified above, the Contract Review Committee considered information provided from time to time by each adviser throughout the year at meetings of the Board and its committees. Over the course of the twelve-month period ended April 30, 2009, the Board met eighteen times and the Contract Review Committee, the Audit Committee, the Governance Committee, the Portfolio Management Committee and the Compliance Reports and Regulatory Matters Committee, each of which is a Committee comprised solely of Independent Trustees, met seven, five, six, six and six times, respectively. At such meetings, the Trustees received, among other things, presentations by the portfolio managers and other investment professionals of each adviser relating to the investment performance of each fund and the investment strategies used in pursuing the fund’s investment objective.

For funds that invest through one or more underlying portfolios, the Board considered similar information about the portfolio(s) when considering the approval of advisory agreements. In addition, in cases where the fund’s investment adviser has engaged a sub-adviser, the Board considered similar information about the sub-adviser when considering the approval of any sub-advisory agreement.

The Contract Review Committee was assisted throughout the contract review process by Goodwin Procter LLP, legal counsel for the Independent Trustees. The members of the Contract Review Committee relied upon the advice of such counsel and their own business judgment in determining the material factors to be considered in evaluating each advisory and sub-advisory agreement and the weight to be given to each such factor. The conclusions reached with respect to each advisory and sub-advisory agreement were based on a comprehensive evaluation of all the information provided and not any single factor. Moreover, each member of the Contract Review Committee may have placed varying emphasis on particular factors in reaching conclusions with respect to each advisory and sub-advisory agreement.

Results of the Process

Based on its consideration of the foregoing, and such other information as it deemed relevant, including the factors and conclusions described below, the Contract Review Committee concluded that the continuance of the investment advisory agreement between Eaton Vance Credit Opportunities Fund (the “Fund”) and Eaton Vance Management (the “Adviser”), including its fee structure, is in the interests of shareholders and, therefore, the Contract Review Committee recommended to the Board approval of the agreement. The Board accepted the recommendation of the Contract Review Committee as well as the factors considered and conclusions reached by the Contract Review Committee with respect to the agreement. Accordingly, the Board, including a majority of the Independent Trustees, voted to approve continuation of the investment advisory agreement for the Fund.

Nature, Extent and Quality of Services

In considering whether to approve the investment advisory agreement of the Fund, the Board evaluated the nature, extent and quality of services provided to the Fund by the Adviser.

The Board considered the Adviser’s management capabilities and investment process with respect to the types of investments held by the Fund, including the education, experience and number of its investment professionals and other personnel who provide portfolio management, investment research, and similar services to the Fund. In particular, the Board evaluated the abilities and experience of such investment personnel in analyzing special considerations relevant to investing in senior secured floating-rate loans. Specifically, the Board noted the experience of the Adviser’s large group of bank loan investment professionals and other personnel who provide services to the Fund, including portfolio managers and analysts. The Board also took into account the resources dedicated to portfolio management and other services, including the compensation paid to recruit and retain investment personnel, and the time and attention devoted to the Fund by senior management.

The Board also reviewed the compliance programs of the Adviser and relevant affiliates thereof. Among other matters, the Board considered compliance and reporting matters relating to personal trading by investment personnel, selective disclosure of portfolio holdings, late trading, frequent trading, portfolio valuation, business continuity and the allocation of investment opportunities. The Board also evaluated the responses of the Adviser and its affiliates to requests from regulatory authorities such as the Securities and Exchange Commission and the Financial Industry Regulatory Authority.

The Board considered shareholder and other administrative services provided or managed by Eaton Vance Management and its affiliates, including transfer agency and accounting services. The Board evaluated the benefits to shareholders of investing in a fund that is a part of a large family of funds.

The Board considered the Adviser’s recommendations for Board action and other steps taken in response to the unprecedented dislocations experienced in the capital markets over recent periods, including sustained periods of high volatility, credit disruption and government intervention. In particular, the Board considered the Adviser’s efforts and expertise with respect to each of the following matters as they relate to the Fund and/or other funds within the Eaton Vance family of funds: (i) negotiating and maintaining the

Eaton Vance Credit Opportunities Fund

BOARD OF TRUSTEES’ ANNUAL APPROVAL OF THE INVESTMENT ADVISORY AGREEMENT CONT’D

availability of bank loan facilities and other sources of credit used for investment purposes or to satisfy liquidity needs; (ii) establishing the fair value of securities and other instruments held in investment portfolios during periods of market volatility and issuer-specific disruptions; and (iii) the ongoing monitoring of investment management processes and risk controls. In addition, the Board considered the Adviser’s actions with respect to the Auction Preferred Shares (“APS”) issued by the Fund, including the Adviser’s efforts to seek alternative forms of debt and other leverage that may over time reduce financing costs associated with APS and enable the Fund to restore liquidity for APS holders.

After consideration of the foregoing factors, among others, the Board concluded that the nature, extent and quality of services provided by the Adviser, taken as a whole, are appropriate and consistent with the terms of the investment advisory agreement.

Fund Performance

The Board compared the Fund’s investment performance to a relevant universe of similarly managed funds identified by an independent data provider and appropriate benchmark indices. The Board reviewed comparative performance data for the one-year period ended September 30, 2008 for the Fund. In light of the Fund’s relatively brief operating history, the Board concluded that additional time was required to evaluate longer term performance of the Fund.

Management Fees and Expenses

The Board reviewed contractual investment advisory fee rates, including any administrative fee rates, payable by the Fund (referred to as “management fees”). As part of its review, the Board considered the management fees and the Fund’s total expense ratio for the year ended September 30, 2008, as compared to a group of similarly managed funds selected by an independent data provider. The Board considered the fact that the Adviser had waived fees and/or paid expenses for the Fund.

After reviewing the foregoing information, and in light of the nature, extent and quality of the services provided by the Adviser, the Board concluded that the management fees charged for advisory and related services and the Fund’s total expense ratio are reasonable.

Profitability

The Board reviewed the level of profits realized by the Adviser and relevant affiliates thereof in providing investment advisory and administrative services to the Fund and to all Eaton Vance Funds as a group. The Board considered the level of profits realized with and without regard to revenue sharing or other payments by the Adviser and its affiliates to third parties in respect of distribution services. The Board also considered other direct or indirect benefits received by the Adviser and its affiliates in connection with its relationship with the Fund.

The Board concluded that, in light of the foregoing factors and the nature, extent and quality of the services rendered, the profits realized by the Adviser and its affiliates are reasonable.

Economies of Scale

In reviewing management fees and profitability, the Board also considered the extent to which the Adviser and its affiliates, on the one hand, and the Fund, on the other hand, can expect to realize benefits from economies of scale as the assets of the Fund increase. The Board acknowledged the difficulty in accurately measuring the benefits resulting from the economies of scale with respect to the management of any specific fund or group of funds. The Board also considered the fact that the Fund is not continuously offered and concluded that, in light of the level of the adviser’s profits with respect to the Fund, the implementation of breakpoints in the advisory fee schedule is not appropriate at this time. Based upon the foregoing, the Board concluded that the benefits from economies of scale are currently being shared equitably by the Adviser and its affiliates and the Fund.
