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 (if applicable) will file a schedule of its 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 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.

Economic and Market Conditions

·During the six months ended October 31, 2008, credit markets experienced unprecedented volatility, and the bank loan market and high-yield bond market were no exception. The subprime crisis of 2007 expanded in 2008 to include nearly all credit instruments, which in turn, caused the world economy to slip into recession. The period was a rollercoaster for the credit markets and for the Fund. The total return for the S&P/LSTA Leveraged Loan Index (the Index) through the first three months of the period was -0.42%, disappointing, but, given the environment, not especially bad compared to other markets. However, September 2008 brought a series of events that rattled the markets more deeply: the bailouts of Fannie Mae and Freddie Mac, the bankruptcy of Lehman Brothers, the rescue of American International Group, Inc. and a litany of unprecedented steps by the U.S. Treasury and the Federal Reserve to stabilize the credit markets. In the Fund’s second fiscal quarter, the Index declined -18.66%, by far its worst quarterly showing ever. The Merrill Lynch U.S. High Yield Index lost 23.0%, the worst quarter on record for the high-yield bond market. At October 31, 2008, the Fund was invested 45.2% in the first lien loan market, 34.5% in the second lien loan market, and 20.3% in the high-yield bond market. In general, these markets represent increasing levels of credit risk. The average first lien loan price at October 31, 2008 was 65.7% of par; the average second lien price was 56% of par; and the average high-yield bond price was 65.4% of par.

·While there is little doubt that a recession would bring higher default rates, it is difficult to reconcile recent trading levels with market fundamentals. A range of credit statistics and criteria used to monitor creditworthiness suggested that overall credit quality appeared to be in line with historical patterns. Despite this, bank loans traded below historical recovery levels, thus implying a near 100% default rate. The most compelling, albeit obvious, explanation for the market’s depressed trading level was that there were more sellers of bank loans than buyers, especially during the Fund’s second quarter. Some selling was forced, especially by hedge funds and structured investment vehicles unable to meet margin requirements. Some selling was voluntary, as redemptions from mutual funds were significant throughout the year. In addition, many hard-pressed banks and investment banks that typically make markets in bank loans were hesitant to own loans and bonds, making trading more volatile. Later in the period, there were signs that many institutional investors were attracted to the asset class by record low loan prices. However, selling clearly outweighed buying, pushing prices lower.

	At Share Price	10.50		%

Please refer to page 4 for additional performance information.

(1)	Performance results reflect the effects of leverage.
(2)	The Distribution Rate is based on the Fund’s most recent monthly distribution per share declared on December 1, 2008 (annualized) divided by the Fund’s NAV or share price at the end of the period. The Fund’s monthly distributions may be comprised of ordinary income, net realized capital gains and return of capital.

Past performance is no guarantee of future results. Returns are historical and are calculated by determining the percentage change in net asset value or share price (as applicable) with all distributions reinvested. The Fund’s performance at share price will differ from its results at NAV. Although share price performance generally reflects investment results over time, during shorter periods, returns at share 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. Absent an expense waiver by the investment adviser, returns would be lower. For performance as of the most recent month end, please refer to www.eatonvance.com.

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.

·During the six months ended October 31, 2008, the high-yield bond market suffered large losses, reflecting the breakdown of the credit markets. Toxic sub- prime loans, mortgage defaults, bank failures and excessive leverage in the financial system took a toll on consumer and investor confidence and dragged the economy into recession. Early in the year, the high-yield market was additionally impacted by a large inventory of unsold bonds issued to finance pending mergers and by a growing risk-aversion among fixed-income investors. The market staged a spirited-but-brief rally in March and April 2008, as the Federal Reserve injected liquidity following the Bear Stearns failure. However, as the dimensions of the global credit crisis became increasingly apparent, the market began a dramatic sell-off. Forced liquidation of bank loans by hedge funds and structured investment vehicles accelerated the process of de-leveraging across the credit markets. The selling pressure was such that liquidity was sharply lower for higher-quality bonds, and all but disappeared for lower-quality bonds. The market decline was most severe in October 2008, declining 16.3% in that month alone, the worst month in the history of the high-yield market. High-yield spreads at October 31, 2008 were around 1,600 basis points (16.00%) – 50% higher than the peak spreads in the previous two recessions.

·A further measure of the sell-off was the high-yield bond distress ratio – the percentage of the market trading at a spread of 1,000 basis points (10.00%) or more. In October 2008, that figure rose to more than 65% of the market, significantly higher than the previous record of 40% in 2002. By October 31, 2008, the market appeared to have discounted a default rate in the mid-teens range, well above historical norms for recessions.

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 very well diversified, with 303 borrowers and no single investment representing more than 1.5% of the total investments. The Fund is also broadly diversified by industry, with none constituting more than 8% at October 31, 2008. A diversified approach should help the Fund mitigate risk in an increasing default environment. At October 31, 2008, defaulted assets represented 3.5% of the Fund’s investments. 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.

·As a result of the previously discussed market dislocation, the market value of the Fund’s investments continued to decline significantly during the six months ended October 31, 2008, resulting in a total return of -39.70% at market price. The Fund’s total return trailed bank loan and high-yield bond indices as a result of leverage on the Fund, which accentuated the negative returns, partially due to a higher concentration of second lien bank loans compared to the Index. During the period, the Fund continued to provide a high level of current income.

·The performance of the Fund’s high-yield bond investments was negatively impacted by its lower allocation in BB-rated bonds relative to the Index, as BB-rated issues outperformed in the difficult market environment. Consumer-discretionary holdings also affected performance negatively. For example, an overweighting in gaming bonds fared poorly, as investors feared the consequences of a cutback in leisure and travel spending. Cyclical areas, such as paper, energy and metals and mining, detracted from performance, as the slower global economy brought lower commodity prices, and weaker demand for packaging materials. The consumer staples sector, which is characteristically less vulnerable to the vagaries of the economy, represented some the Fund’s better performers. Securities selection in the food and beverages, health care and utilities industries helped performance, as these bonds suffered less dramatic losses than more economically-sensitive areas. The Fund was helped by underweightings in the automotive and home building areas, which were among the hardest-hit industries in the U.S. economy. The Fund was also helped by an underweighting in the troubled financial sector. The Fund had no exposure to commercial banks, which deteriorated amid growing loan losses.

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. Fund information provided in the report may not be representative of the Fund’s current or future investments and may change due to active management.

·As of October 31, 2008, the Fund had outstanding leverage of approximately 45.8% of its total net assets.(1) The Fund’s leverage consists of auction preferred shares issued by the Fund (“APS”) and borrowings under a revolving credit and security agreement with conduit lenders and a bank. Pursuant to applicable law and provisions of the Fund’s governing documents relating to the use of leverage, the Fund may not declare dividends or other distributions on common shares if it does not maintain asset coverage in certain prescribed amounts. As the result of sharp declines in the value of the Fund’s investments in recent months, the Fund sold investments to reduce outstanding leverage and maintain the required asset coverage. During the six months ended October 31, 2008, the Fund’s outstanding borrowings were reduced by approximately $28 million for this reason. If credit markets remain volatile, additional actions may be required to maintain the Fund’s asset coverage, including additional sales of investments and possibly a reduction in dividend payment rates. In the event of an improvement in asset coverage, the Fund has the ability to increase borrowings under the revolving credit and security aggreement.

(1) 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 Auction Preferred Shares and borrowings.

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

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 1940Act), 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  Investment Valuation — Interests in senior floating-rate loans for which reliable market quotations are readily available are valued generally at the average mean of bid and ask quotations obtained from an independent 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 following valuation techniques: (i) a matrix pricing approach that considers the yield on the Senior Loan relative to yields on other loan interests issued by companies of comparable credit quality; (ii) a comparison of the value of the borrower's outstanding equity and debt to that of comparable public companies; (iii) a discounted cash flow analysis; or (iv) 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 listed securities and securities for which quotations are available, will normally be valued on the basis of market quotations provided by independent pricing services. The pricing services consider various factors relating to bonds and/or market transactions to determine market value. Short-term debt securities with a remaining maturity of sixty days or less are valued at amortized cost, which approximates market value. If short-term debt securities are acquired with a remaining maturity of more than sixty days, they will be valued by a pricing service. Equity securities 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 an independent pricing service. Forward foreign currency exchange contracts are generally valued using prices supplied by a pricing vendor or dealers. Interest rate swaps and floors are normally valued using valuations provided by a pricing vendor. Such vendor valuations are based on the present value of fixed and projected floating rate cash flows over the term of the swap contract. Future cash flows are discounted to their present value using swap curves 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 an independent quotation service. The independent 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 are valued at fair value using methods determined in good faith by or at the direction of the Trustees of the Fund considering relevant factors, data and information including the market value of freely tradable securities of the same class in the principal market on which such securities are normally traded.

Eaton Vance Credit Opportunities Fund as of October 31, 2008

NOTES TO FINANCIAL STATEMENTS (Unaudited)CONT'D

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 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 based on available market quotations provided by a pricing service.

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, 2008, the Fund, for federal income tax purposes, had a capital loss carryforward of $833,774 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.

As of October 31, 2008, 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 30, 2006 to April 30, 2008 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.

22

Eaton Vance Credit Opportunities Fund as of October 31, 2008

NOTES TO FINANCIAL STATEMENTS (Unaudited)CONT'D

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  Statement of Cash Flows — The cash amount shown in the Statement of Cash Flows of the Fund is the amount included in the Fund's Statement of Assets and Liabilities and represents the cash on hand at its custodian and does not include any short-term investments.

M  Interim Financial Statements — The interim financial statements relating to October 31, 2008 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 APSauctions are successful. Auctions have not cleared since February13, 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, 2008, the Fund made a partial redemption of its APS at a liquidation price of $25,000 per share, the financing for which was provided by a committed financing arrangement (see Note 10). The number of APS redeemed and redemption amount (excluding the final dividend payment) during the six months ended October 31, 2008 and the number of APS issued and outstanding as of October 31, 2008 are as follows:

APS Redeemed During the Period		Redemption Amount		APS Issued and Outstanding
	2,167	$	54,175,000		1,083

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 coverage with respect to the APS as defined in the Fund's By-Laws and the 1940 Act. The Fund pays an annual fee equivalent to 0.25% of the liquidation value of the APS for the remarketing efforts associated with the APS to broker-dealers as a service fee.

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

23

Eaton Vance Credit Opportunities Fund as of October 31, 2008

NOTES TO FINANCIAL STATEMENTS (Unaudited)CONT'D

and are payable at the end of each dividend period. The dividend rate for the APS at October 31, 2008 was 4.28%. For the six months ended October 31, 2008, the amount of dividends paid (including capital gains, if any) to APS shareholders was $607,230, representing an average APS dividend rate of 4.46% (annualized) and dividend rate ranges of 3.67% to 7.15%.

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, 2008.

The Fund distinguishes between distributions on a tax basis and financial reporting basis. Accouting 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 purpose, distributions from short-term capital gains are considered to be from ordinary income.

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, 2008, the Fund's adviser fee totaled $693,319 of which $10,965 was allocated from Cash Management and $682,354 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 $182,343 of its adviser fee for the six months ended October 31, 2008.

EVM has further agreed to waive its adviser fee to the extent that the cost of the committed financing to partially redeem the APS is greater than the dividend and preferred shares service fee that would have been incurred had the APS not been redeemed, hereafter referred to as "incremental cost". Such waiver is calculated as the lesser of 50% of the Fund's adviser fee on assets attributable to the committed financing or the incremental cost and will remain in effect until October 31, 2009. No such waiver was required for the six months ended October 31, 2008.

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, 2008, 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 $20,200,634 and $50,031,568, respectively, for the six months ended October 31, 2008.

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, 2008. Common shares issued pursuant to the Fund's dividend reinvestment plan for the year ended April 30, 2008 were 85,480.

8  Restricted Securities

At October 31, 2008, the Fund owned the following security (representing 0.1% of net assets applicable to common shares) which was restricted as to 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 restricted securities. The value of restricted 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.

Description	Date of Acquisition	Units		Cost		Value
Preferred Stock
Fontainebleau Resorts LLC (PIK)	6/1/07		198	$	198,020	$	53,070
Total Restricted Securities			198	$	198,020	$	53,070

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, 2008 is as follows:

Forward Foreign Currency Exchange Contracts

Sales

Settlement Date	Deliver	In Exchange For	Net Unrealized Appreciation
5/30/08	British Pound Sterling 3,729,632	United States Dollar 6,104,550	$	111,218
5/30/08	Euro 8,575,911	United States Dollar 11,106,834		186,559
			$	297,777

At October 31, 2008, the Fund had sufficient cash and/or securities to cover commitments under these securities.

10  Revolving Credit and Security Agreement

Effective April 11, 2008, the Fund entered into a Revolving Credit and Security Agreement, as amended (the Agreement) with conduit lenders and a bank to borrow up to an initial limit of $54,175,000 for a period of five years, the proceeds of which were used to partially redeem the Fund's APS (see Note 2). The Agreement provides for a renewable 364-day backstop financing arrangement, which ensures that alternate financing will continue to be available to the Fund should the conduits be unable to place their commercial paper. Borrowings under the Agreement are secured by the assets of the Fund. Interest is charged at a rate above the conduits' commercial paper issuance rate and is payable monthly. Under the terms of the Agreement, the Fund pays a monthly program fee of 1.25% per annum (0.60% per annum prior to October 31, 2008) on its outstanding borrowings to administer the facility and a monthly liquidity fee of 1.25% per annum (0.40% per annum prior to October 31, 2008) on the borrowing limit under the Agreement. The Fund also paid a structuring fee of $541,750, which is being amortized to interest expense over a period of five years. The unamortized balance at October 31, 2008 is approximately $499,000 and is included in prepaid expenses on the Statement of Assets and Liabilities. The Fund is required to maintain certain net asset levels during the term of the Agreement. At October 31, 2008, the Fund had borrowings outstanding under the Agreement of $26,175,000 at an interest rate of 3.72%. For the period from May 2, 2008, the date of the initial draw on the Agreement, through October 31, 2008, the average borrowings under the Agreement and the average interest rate (annualized) were $51,147,678 and 3.01%, respectively.

11  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

25

Eaton Vance Credit Opportunities Fund as of October 31, 2008

NOTES TO FINANCIAL STATEMENTS (Unaudited)CONT'D

removal of funds or other assets of the Fund, political or financial instability or diplomatic and other developments which could affect such investments. Foreign stock 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.

12  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.

13  Fair Value Measurements

The Fund adopted Financial Accounting Standards Board(FASB) Statement of Financial Accounting Standards No. 157 (FAS 157), "Fair Value Measurements", effective May 1, 2008. FAS 157 established a three-tier hierarchy to prioritize the assumptions, referred to as inputs, 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, 2008, the inputs used in valuing the Fund's investments, which are carried at value, were as follows:

	Valuation Inputs	Investments in Securities		Other Financial Instruments*
Level 1	Quoted Prices	$	—	$	297,777
Level 2	Other Significant Observable Inputs		105,421,933		—
Level 3	Significant Unobservable Inputs		2,037,109		—
Total		$	107,459,042	$	297,777

*Other financial instruments are forward foreign currency exchange contracts not reflected in the Portfolio of Investments, which are valued at the unrealized appreciation (depreciation) on the instrument.

The following is a reconciliation of Level 3 assets for which significant unobservable inputs were used to determine fair value:

	Investments in Securities
Balance as of April 30, 2008	$	1,105,998
Realized gains (losses)		(2,517	)
Change in net unrealized appreciation (depreciation)		(302,713	)
Net purchases (sales)		14,434
Accrued discount (premium)		4,125
Net transfers to (from) Level 3		1,217,782
Balance as of October 31, 2008	$	2,037,109

14  Recently Issued Accounting Pronouncement

In March 2008, the FASB issued Statement of Financial Accounting Standards No. 161 (FAS 161), "Disclosures about Derivative Instruments and Hedging Activities". FAS 161 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. FAS 161 is effective for fiscal years and interim periods beginning after November 15, 2008. Management is currently evaluating the impact the adoption of FAS 161 will have on the Fund's financial statement disclosures.

Eaton Vance Credit Opportunities Fund

DIVIDEND REINVESTMENT PLAN

The Fund offers a dividend reinvestment plan (the Plan) pursuant to which shareholders automatically have dividends and capital gains distributions reinvested in common shares (the Shares) of the Fund unless they elect otherwise through their investment dealer. On the distribution payment date, if the net asset value per Share is equal to or less than the market price per Share plus estimated brokerage commissions then new Shares will be issued. The number of Shares shall be determined by the greater of the net asset value per Share or 95% of the market price. Otherwise, Shares generally will be purchased on the open market by the Plan Agent. Distributions subject to income tax (if any) are taxable whether or not shares are reinvested.

If your shares are in the name of a brokerage firm, bank, or other nominee, you can ask the firm or nominee to participate in the Plan on your behalf. If the nominee does not offer the Plan, you will need to request that your shares be re-registered in your name with the Fund's transfer agent, American Stock Transfer & Trust Company, or you will not be able to participate.

The Plan Agent's service fee for handling distributions will be paid by the Fund. Each participant will be charged their pro rata share of brokerage commissions on all open-market purchases.

Plan participants may withdraw from the Plan at any time by writing to the Plan Agent at the address noted on the following page. If you withdraw, you will receive shares in your name for all Shares credited to your account under the Plan. If a participant elects by written notice to the Plan Agent to have the Plan Agent sell part or all of his or her Shares and remit the proceeds, the Plan Agent is authorized to deduct a $5.00 fee plus brokerage commissions from the proceeds.

If you wish to participate in the Plan and your shares are held in your own name, you may complete the form on the following page and deliver it to the Plan Agent.

Any inquiries regarding the Plan can be directed to the Plan Agent, American Stock Transfer & Trust Company, at 1-866-439-6787.

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 21, 2008, 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 2008. 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

•  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;

Other Relevant Information

•  Information concerning the nature, cost and character of the administrative and other non-investment management services provided by Eaton Vance Management and its affiliates;

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, 2008, the Board met eleven times and the Contract Review Committee, the Audit Committee and the Governance Committee, each of which is a Committee comprised solely of Independent Trustees, met twelve, seven and five 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. The Portfolio Management Committee and the Compliance Reports and Regulatory Matters Committee are newly established and did not meet during the twelve-month period ended April 30, 2008.

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 the 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.

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. 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, 2007 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, 2007, 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.
