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.

However, the small-cap universe showed signs of renewal as the period ended. The S&P SmallCap 600 Index had a total return of 3.54% for the six months ended April 30, 2003.(1) - - The recent passage of the federal tax cut could provide a measure of stimulus for the economy. Historically, following a period of economic malaise, smaller companies have been among the first to benefit from an accelerating economy. THE FUND - - The Fund's Class A shares had a total return of 5.42% during the six months ended April 30, 2003.(2) This return resulted from an increase in net asset value (NAV) per share to $9.34 on April 30, 2003 from $8.86 on October 31, 2002. - - The Fund's Class B shares had a total return of 4.99% during the six months ended April 30, 2003.(2) This return resulted from an increase in NAV per share to $9.26 on April 30, 2003 from $8.82 on October 31, 2002. - - The Fund's Class C shares had a total return of 4.99% during the six months ended April 30, 2003.(2) This return resulted from an increase in NAV per share to $9.26 on April 30, 2003 from $8.82 on October 31, 2002. THE VIEWS EXPRESSED IN THIS REPORT ARE THOSE OF THE PORTFOLIO MANAGER 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 FOX ASSET MANAGEMENT DISCLAIMS ANY RESPONSIBILITY TO UPDATE SUCH VIEWS. THESE VIEWS MAY NOT BE RELIED ON AS INVESTMENT ADVICE AND, BECAUSE INVESTMENT DECISIONS ARE BASED ON MANY FACTORS, MAY NOT BE RELIED ON AS AN INDICATION OF TRADING INTENT ON BEHALF OF ANY FUND. MANAGEMENT DISCUSSION - - The Fund focuses on small-cap companies that management believes are inexpensive relative to the overall stock market. In addition, the Fund pursues a variety of tax-managed strategies designed to avoid taxable distributions. This tax-managed approach allows investors to participate more fully in the growth of small companies, while considering the tax events that can reduce investment returns. - - While the economy has awaited a convincing recovery, stock selection has remained of paramount importance. The Portfolio emphasized companies we believe have good fundamentals, strong balance sheets and relatively low valuation, and has sought a balance between cyclical and consumer stocks. The Portfolio's largest sector weightings at April 30, 2003 were energy, medical services and supplies, industrial products and retailing. - - Energy stocks played a prominent role in the Portfolio and performed relatively well. Natural gas companies benefited from rising gas prices, which were high even by seasonal standards. Prices were boosted by an unusually severe winter and by concerns over the availability of long-term gas supplies. - - Medical services and supplies stocks were among the Portfolio's best performers during the period. A prime beneficiary of advances in medical technology, the group has enjoyed relatively strong revenue growth, even as other segments of the economy have struggled with declining demand. - - Although consumers were increasingly beleaguered in recent months, the Portfolio's restaurant stocks fared unusually well. While "fast-food" chains have been troubled by issues of nutrition and cleanliness, other companies have achieved impressive revenue growth through a blend of attractive casual dining concepts and value-priced menus. - - Some of the Portfolio's cyclical holdings fared less well. Transportation and chemicals continued to experience subpar revenues, as demand remained weak amid the slow recovery.

(2) These returns do not include the 5.75% maximum sales charge for the Fund's Class A shares or the applicable contingent deferred sales charges (CDSC) for Class B and Class C shares. (3) Returns are historical and are calculated by determining the percentage change in net asset value with all distributions reinvested. SEC average annual returns for Class A reflect a 5.75% sales charge; for Class B, returns reflect applicable CDSC based on the following schedule: 5%-1st and 2nd years; 4%-3rd year; 3%-4th year; 2%-5th year; 1%-6th year; for Class C, 1-year return reflects 1% CDSC. (4) Based on market value. Ten largest holdings represent 31.7% of the Portfolio's net assets. Holdings are subject to change. Past performance is no guarantee of future results. Investment return and principal value will fluctuate so that shares, when redeemed, may be worth more or less than their original cost. 2 <Page> EATON VANCE TAX-MANAGED SMALL-CAP VALUE FUND AS OF APRIL 30, 2003 PERFORMANCE The tables below set forth the pre-tax and after-tax performance for the Fund. After-tax performance reflects the impact of federal income taxes on Fund distributions of dividends and capital gains, as well as capital gains taxes on the sale of Fund shares, while pre-tax performance does not. Because the objective of the Fund is to provide long-term, after-tax returns to shareholders, it is important for investors to know the effect of taxes on the Fund's return. AVERAGE ANNUAL TOTAL RETURNS (FOR THE PERIOD ENDED APRIL 30, 2003) RETURNS AT NET ASSET VALUE (NAV) (CLASS A) <Table> <Caption> ONE YEAR LIFE OF FUND Return Before Taxes -14.00% -5.67% Return After Taxes on Distributions -14.00% -5.67% Return After Taxes on Distributions -9.10% -4.53% and Sale of Fund Shares </Table> RETURNS AT PUBLIC OFFERING PRICE (POP) (CLASS A) <Table> <Caption> ONE YEAR LIFE OF FUND Return Before Taxes -18.92% -10.32% Return After Taxes on Distributions -18.92% -10.32% Return After Taxes on Distributions -12.30% -8.24% and Sale of Fund Shares </Table> AVERAGE ANNUAL TOTAL RETURNS (FOR THE PERIOD ENDED APRIL 30, 2003) RETURNS AT NET ASSET VALUE (NAV) (CLASS B) <Table> <Caption> ONE YEAR LIFE OF FUND Return Before Taxes -14.65% -6.36% Return After Taxes on Distributions -14.65% -6.36% Return After Taxes on Distributions -9.52% -5.08% and Sale of Fund Shares </Table> RETURNS AT PUBLIC OFFERING PRICE (POP) (CLASS B) <Table> <Caption> ONE YEAR LIFE OF FUND Return Before Taxes -18.92% -10.38% Return After Taxes on Distributions -18.92% -10.38% Return After Taxes on Distributions -12.30% -8.29% and Sale of Fund Shares </Table> RETURNS AT NET ASSET VALUE (NAV) (CLASS C) <Table> <Caption> ONE YEAR LIFE OF FUND Return Before Taxes -14.65% -6.36% Return After Taxes on Distributions -14.65% -6.36% Return After Taxes on Distributions -9.52% -5.08% and Sale of Fund Shares </Table> RETURNS AT PUBLIC OFFERING PRICE (POP) (CLASS C) <Table> <Caption> ONE YEAR LIFE OF FUND Return Before Taxes -15.51% -6.36% Return After Taxes on Distributions -15.51% -6.36% Return After Taxes on Distributions -10.08% -5.08% and Sale of Fund Shares </Table> Class A, Class B and Class C commenced operations on 3/4/02. Returns at Public Offering Price (POP) reflect the deduction of the maximum sales charge, while Returns at Net Asset Value (NAV) do not. After-tax returns are calculated using the highest historical individual federal income tax rate and do not reflect the impact of state and local taxes. Actual after-tax returns depend on a shareholder's tax situation and may differ from those shown. After-tax returns are not relevant for shareholders who hold shares in tax-deferred accounts or to shares held by non-taxable entities. Return After Taxes on Distributions for a period may be the same as Return Before Taxes for that period because no distributions were paid during that period or because the taxable portion of distributions made during the period was insignificant. Also, Return After Taxes on Distributions and Sale of Fund Shares for a period may be greater than Return After Taxes on Distributions for the same period because of realized losses on the sale of Fund shares. Past performance (both before and after taxes) is no guarantee of future results. Investment return and principal value will fluctuate so that shares, when redeemed, 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 different. 3 <Page> EATON VANCE TAX-MANAGED SMALL-CAP VALUE FUND AS OF APRIL 30, 2003 FINANCIAL STATEMENTS (UNAUDITED) STATEMENT OF ASSETS AND LIABILITIES <Table> <Caption> AS OF APRIL 30, 2003 Assets - ----------------------------------------------------- Investment in Tax-Managed Small-Cap Value Portfolio (Portfolio), at value (identified cost, $11,258,998) $10,703,662 Receivable for Fund shares sold 426 Receivable from affiliate 78,927 - ----------------------------------------------------- TOTAL ASSETS $10,783,015 - ----------------------------------------------------- Liabilities - ----------------------------------------------------- Payable for Fund shares redeemed $ 6,036 Payable to affiliate for distribution and service fees 1,932 Payable to affiliate for Trustees' fees 80 Accrued expenses 20,094 - ----------------------------------------------------- TOTAL LIABILITIES $ 28,142 - ----------------------------------------------------- NET ASSETS $10,754,873 - ----------------------------------------------------- Sources of Net Assets - ----------------------------------------------------- Paid-in capital $11,540,876 Accumulated net realized loss from Portfolio (computed on the basis of identified cost) (186,094) Accumulated net investment loss (44,573) Net unrealized depreciation from Portfolio (computed on the basis of identified cost) (555,336) - ----------------------------------------------------- TOTAL $10,754,873 - ----------------------------------------------------- Class A Shares - ----------------------------------------------------- NET ASSETS $ 4,427,968 SHARES OUTSTANDING 474,308 NET ASSET VALUE AND REDEMPTION PRICE PER SHARE (net assets DIVIDED BY shares of beneficial interest outstanding) $ 9.34 MAXIMUM OFFERING PRICE PER SHARE (100 DIVIDED BY 94.25 of $9.34) $ 9.91 - ----------------------------------------------------- Class B Shares - ----------------------------------------------------- NET ASSETS $ 3,625,214 SHARES OUTSTANDING 391,453 NET ASSET VALUE, OFFERING PRICE AND REDEMPTION PRICE PER SHARE (net assets DIVIDED BY shares of beneficial interest outstanding) $ 9.26 - ----------------------------------------------------- Class C Shares - ----------------------------------------------------- NET ASSETS $ 2,701,691 SHARES OUTSTANDING 291,717 NET ASSET VALUE, OFFERING PRICE AND REDEMPTION PRICE PER SHARE (net assets DIVIDED BY shares of beneficial interest outstanding) $ 9.26 - ----------------------------------------------------- </Table> On sales of $50,000 or more, the offering price of Class A shares is reduced.

SEE NOTES TO FINANCIAL STATEMENTS 8 <Page> EATON VANCE TAX-MANAGED SMALL-CAP VALUE FUND AS OF APRIL 30, 2003 NOTES TO FINANCIAL STATEMENTS (UNAUDITED) 1 Significant Accounting Policies - ------------------------------------------- Eaton Vance Tax-Managed Small-Cap Value Fund (the Fund) is a diversified series of Eaton Vance Mutual Funds Trust (the Trust). The Trust is an entity of the type commonly known as a Massachusetts business trust and is registered under the Investment Company Act of 1940, as amended, as an open-end management investment company. The Fund offers three classes of shares. Class A shares are generally sold subject to a sales charge imposed at time of purchase. Class B and Class C shares are sold at net asset value and are generally subject to a contingent deferred sales charge (see Note 6). Class B shares held for eight years will automatically convert to Class A shares. Each class represents a pro rata interest in the Fund, but votes separately on class-specific matters and (as noted below) is subject to different expenses. Realized and unrealized gains and losses and net investment income and losses, other than class-specific expenses, are allocated daily to each class of shares based on the relative net assets of each class to the total net assets of the Fund. Each class of shares differs in its distribution plan and certain other class-specific expenses. The Fund invests all of its investable assets in interests of the Tax-Managed Small- Cap Value Portfolio (the Portfolio), a New York Trust, having the same investment objective as the Fund. The value of the Fund's investment in the Portfolio reflects the Fund's proportionate interest in the net assets of the Portfolio (40.2% at April 30, 2003). The performance of the Fund is directly affected by the performance of the Portfolio. The financial statements of the Portfolio, including the Portfolio of Investments, are included elsewhere in this report and should be read in conjunction with the Fund's financial statements. The following is a summary of significant accounting policies consistently followed by the Fund in the preparation of its financial statements. The policies are in conformity with accounting principles generally accepted in the United States of America. A Investment Valuation -- Valuation of securities by the Portfolio is discussed in Note 1A of the Portfolio's Notes to Financial Statements which are included elsewhere in this report. B Income -- The Fund's net investment income or loss consists of the Fund's pro-rata share of the net investment income or loss of the Portfolio, less all actual and accrued expenses of the Fund, determined in accordance with accounting principles generally accepted in the United States of America. C Expenses -- The majority of expenses of the Trust are directly identifiable to an individual fund. Expenses which are not readily identifiable to a specific fund are allocated taking into consideration, among other things, the nature and type of expense and the relative size of the funds. 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, all of its net investment income, and any net realized capital gains. Accordingly, no provision for federal income or excise tax is necessary. At October 31, 2002, the Fund, for federal income tax purposes, had a capital loss carryover of $26,003 which will reduce the taxable income arising from future net realized gain on investments, 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 loss carryover will expire on October 31, 2010. E Other -- Investment transactions are accounted for on a trade-date basis. Dividends to shareholders are recorded on the ex-dividend date. F 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. G Interim Financial Statements -- The interim financial statements relating to April 30, 2003 and for the six months then ended have not been audited by independent certified public accountants, 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 Distributions to Shareholders - ------------------------------------------- It is the present policy of the Fund to make at least one distribution annually (normally in December) of all or substantially all of its net investment income, if any, and at least one distribution annually of all or substantially all of its net realized capital gains, if any. Distributions are paid in the form of additional shares of the Fund or, at the election of the shareholder, in cash. Shareholders may 9 <Page> EATON VANCE TAX-MANAGED SMALL-CAP VALUE FUND AS OF APRIL 30, 2003 NOTES TO FINANCIAL STATEMENTS (UNAUDITED) CONT'D reinvest all distributions in additional shares of the Fund at the net asset value as of the close of business on the ex-dividend date. 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. 3 Shares of Beneficial Interest - ------------------------------------------- The Fund's Declaration of Trust permits the Trustees to issue an unlimited number of full and fractional shares of beneficial interest (without par value). Transactions in Fund shares were as follows: <Table> <Caption> SIX MONTHS ENDED APRIL 30, 2003 PERIOD ENDED CLASS A (UNAUDITED) OCTOBER 31, 2002(1) ------------------------------------------------------------------------------- Sales 188,092 417,251 Redemptions (64,412) (66,623) ------------------------------------------------------------------------------- NET INCREASE 123,680 350,628 ------------------------------------------------------------------------------- </Table> <Table> <Caption> SIX MONTHS ENDED APRIL 30, 2003 PERIOD ENDED CLASS B (UNAUDITED) OCTOBER 31, 2002(1) ------------------------------------------------------------------------------- Sales 180,955 351,931 Redemptions (52,915) (88,518) ------------------------------------------------------------------------------- NET INCREASE 128,040 263,413 ------------------------------------------------------------------------------- </Table> <Table> <Caption> SIX MONTHS ENDED APRIL 30, 2003 PERIOD ENDED CLASS C (UNAUDITED) OCTOBER 31, 2002(1) ------------------------------------------------------------------------------- Sales 117,915 237,199 Redemptions (37,379) (26,018) ------------------------------------------------------------------------------- NET INCREASE 80,536 211,181 ------------------------------------------------------------------------------- </Table> (1) For the period from the start of business, March 4, 2002, to October 31, 2002. 4 Transactions with Affiliates - ------------------------------------------- The administration fee is earned by Eaton Vance Management (EVM) as compensation for managing and administering the business affairs of the Fund. Under the administration agreement, EVM earns a fee in the amount of 0.15% per annum of average daily net assets of the Fund. For the six months ended April 30, 2003, the administration fee amounted to $6,871. To reduce the net investment loss of the Fund, EVM was allocated $78,927 of the Fund's operating expenses for the six months ended April 30, 2003. The Portfolio has engaged Boston Management and Research (BMR), a subsidiary of EVM, to render investment advisory services. See Note 2 of the Portfolio's Notes to Financial Statements which are included elsewhere in this report. Effective August 1, 2002, EVM serves as the sub-transfer agent of the Fund and receives from the transfer agent an aggregate fee based upon the actual expenses incurred by EVM in the performance of those services. For the six months ended April 30, 2003, no significant amounts have been accrued or paid. Except for Trustees of the Fund and the Portfolio who are not members of EVM's or BMR's organization, officers and Trustees receive remuneration for their services to the Fund out of the investment adviser fee earned by BMR. Trustees of the Fund that are not affiliated with EVM or BMR 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 April 30, 2003, no significant amounts have been deferred. Eaton Vance Distributors, Inc. (EVD), a subsidiary of EVM and the Fund's principal underwriter, received $2,524 as its portion of the sales charge on sales of Class A shares for the six months ended April 30, 2003. Certain officers and Trustees of the Fund and of the Portfolio are officers of the above organizations. 5 Distribution and Service Plans - ------------------------------------------- The Fund has in effect distribution plans for Class B shares (Class B Plan), and Class C shares (Class C Plan), pursuant to Rule 12b-1 under the Investment Company Act of 1940 and a service plan for Class A shares (Class A Plan) (collectively, the Plans). The Class B and Class C Plans require the Fund to pay EVD amounts equal to 1/365 of 0.75% of the Fund's average daily net assets attributable to Class B and Class C shares, for providing ongoing distribution services and facilities to the Fund. The Fund will automatically discontinue payments to EVD during any period in which there are no outstanding Uncovered Distribution Charges, which are equivalent to the sum of (i) 6.25% of the aggregate amount received by the Fund for the Class B and Class C shares sold, plus (ii) interest calculated by applying the rate of 1% over the prevailing prime rate to the outstanding balance of Uncovered Distribution Charges of EVD, of each respective class, reduced by the aggregate amount of contingent deferred 10 <Page> EATON VANCE TAX-MANAGED SMALL-CAP VALUE FUND AS OF APRIL 30, 2003 NOTES TO FINANCIAL STATEMENTS (UNAUDITED) CONT'D sales charges (see Note 6) and daily amounts theretofore paid to EVD by each respective class. The Fund paid or accrued $11,355 and $8,354 for Class B and Class C shares, respectively, to or payable to EVD for the six months ended April 30, 2003, representing 0.75% (annualized) of the average daily net assets for Class B and Class C shares, respectively. At April 30, 2003, the amount of Uncovered Distribution Charges of EVD calculated under the Plans was approximately $169,000 and $140,000 for Class B and Class C shares, respectively. The Plans authorize the Fund to make payments of service fees to EVD, investment dealers and other persons in amounts equal to 0.25% (annualized) of the Fund's average daily net assets attributable to Class A, Class B and Class C shares for each fiscal year. Service fee payments are made for personal services and/or the maintenance of shareholder accounts. Service fees are separate and distinct from the sales commissions and distribution fees payable by the Fund to EVD and, as such, are not subject to automatic discontinuance when there are no outstanding Uncovered Distribution Charges of EVD. Service fees for the six months ended April 30, 2003 amounted to $4,796, $3,785, and $2,785 for Class A, Class B and Class C shares, respectively. 6 Contingent Deferred Sales Charge - ------------------------------------------- A contingent deferred sales charge (CDSC) generally is imposed on redemptions of Class B shares made within six years of purchase and on redemptions of Class C shares made within one year of purchase. Generally, the CDSC is based upon the lower of the net asset value at date of redemption or date of purchase. No charge is levied on shares acquired by reinvestment of dividends or capital gain distributions. Class A shares may be subject to a 1% CDSC if redeemed within one year of purchase (depending upon the circumstances of purchase). The Class B CDSC is imposed at declining rates that begin at 5% in the case of redemptions in the first and second year after purchase, declining one percentage point each subsequent year. Class C shares will be subject to a 1% CDSC if redeemed within one year of purchase. No CDSC is levied on shares which have been sold to EVM or its affiliates or to their respective employees or clients and may be waived under certain other limited conditions. CDSC pertaining to Class B and Class C redemptions are paid to EVD to reduce the amount of Uncovered Distribution Charges calculated under the Class B and Class C Plans, respectively (see Note 5). CDSC assessed on Class B and Class C shares when no Uncovered Distribution Charges exist for the respective classes will be credited to the Fund. EVD received approximately $100, $3,000 and $300 of CDSC paid by shareholders for Class A shares, Class B shares and Class C shares, respectively, for the six months ended April 30, 2003. 7 Investment Transactions - ------------------------------------------- Increases and decreases in the Fund's investment in the Portfolio aggregated $4,398,459 and $1,410,943, respectively, for the six months ended April 30, 2003. 11 <Page> TAX-MANAGED SMALL-CAP VALUE PORTFOLIO AS OF APRIL 30, 2003 PORTFOLIO OF INVESTMENTS (UNAUDITED) COMMON STOCKS -- 90.0% <Table> <Caption> SECURITY SHARES VALUE - -------------------------------------------------------------- Auto Related -- 3.9% - -------------------------------------------------------------- BorgWarner, Inc. 14,500 $ 850,715 Superior Industries International, Inc. 5,000 194,150 - -------------------------------------------------------------- $ 1,044,865 - -------------------------------------------------------------- Cement -- 3.2% - -------------------------------------------------------------- Lafarge North America, Inc. 27,000 $ 859,950 - -------------------------------------------------------------- $ 859,950 - -------------------------------------------------------------- Chemical -- 2.9% - -------------------------------------------------------------- RPM, Inc. 63,000 $ 778,680 - -------------------------------------------------------------- $ 778,680 - -------------------------------------------------------------- Computer / Communications Related -- 5.9% - -------------------------------------------------------------- Actel Corp.(1) 25,000 $ 495,250 International Rectifier Corp.(1) 27,000 610,740 Veeco Instruments, Inc.(1) 29,000 466,610 - -------------------------------------------------------------- $ 1,572,600 - -------------------------------------------------------------- Construction / Engineering -- 4.0% - -------------------------------------------------------------- Granite Construction, Inc. 32,000 $ 537,600 Insituform Technologies, Inc.(1) 33,000 526,350 - -------------------------------------------------------------- $ 1,063,950 - -------------------------------------------------------------- Electrical Equipment -- 2.3% - -------------------------------------------------------------- Belden, Inc. 40,000 $ 475,600 Cable Design Technologies Corp.(1) 18,100 125,071 - -------------------------------------------------------------- $ 600,671 - -------------------------------------------------------------- Electronics -- 3.3% - -------------------------------------------------------------- Bel Fuse, Inc., Class B 30,800 $ 606,760 Technitrol, Inc.(1) 18,000 284,220 - -------------------------------------------------------------- $ 890,980 - -------------------------------------------------------------- Energy -- 11.3% - -------------------------------------------------------------- Newfield Exploration Co.(1) 21,000 $ 722,190 NUI Corp. 19,000 267,330 Piedmont Natural Gas Co., Inc. 20,000 747,200 Questar Corp. 24,500 739,900 <Caption> SECURITY SHARES VALUE - -------------------------------------------------------------- Energy (continued) - -------------------------------------------------------------- XTO Energy, Inc. 27,333 532,993 - -------------------------------------------------------------- $ 3,009,613 - -------------------------------------------------------------- Food Wholesalers / Retailers -- 2.1% - -------------------------------------------------------------- SUPERVALU, Inc. 34,000 $ 559,980 - -------------------------------------------------------------- $ 559,980 - -------------------------------------------------------------- Household Products -- 5.6% - -------------------------------------------------------------- Church & Dwight Co., Inc. 31,000 $ 975,570 Libbey, Inc. 23,000 517,040 - -------------------------------------------------------------- $ 1,492,610 - -------------------------------------------------------------- Industrial Products -- 7.1% - -------------------------------------------------------------- A.O.

SEE NOTES TO FINANCIAL STATEMENTS 16 <Page> TAX-MANAGED SMALL-CAP VALUE PORTFOLIO AS OF APRIL 30, 2003 NOTES TO FINANCIAL STATEMENTS (UNAUDITED) 1 Significant Accounting Policies - ------------------------------------------- Tax-Managed Small-Cap Value Portfolio (the Portfolio) is registered under the Investment Company Act of 1940, as amended, as a diversified open-end management investment company. The Portfolio, which was organized as a trust under the laws of the State of New York on December 10, 2001, seeks to achieve long-term after-tax returns by investing in a diversified portfolio of value stocks of small-cap companies. The Declaration of Trust permits the Trustees to issue interests in the Portfolio. At April 30, 2003, the Eaton Vance Tax-Managed Small-Cap Value Fund held an approximate 40.2% interest in the Portfolio and one other investor owned an interest greater than 10% that equaled 59.5%. The following is a summary of significant accounting policies consistently followed by the Portfolio in the preparation of its financial statements. The policies are in conformity with accounting principles generally accepted in the United States of America. A Investment Valuation -- Marketable securities, including options, that are listed on foreign or U.S. securities exchanges are valued at closing sale prices on the exchange where such securities are principally traded. Marketable securities listed in the NASDAQ National Market System are valued at the NASDAQ official closing price. Unlisted or listed securities for which closing sale prices are not available are generally valued at the mean between the latest bid and asked prices. Futures positions on securities or currencies are generally valued at closing settlement prices. Short-term debt securities with a remaining maturity of 60 days or less are valued at amortized cost, which approximates fair value. Other fixed income and debt securities, including listed securities and securities for which price quotations are available, will normally be valued on the basis of valuations furnished by a pricing service. Investments for which valuations or market quotations are unavailable are valued at fair value using methods determined in good faith by or at the direction of the Trustees. B Income -- Dividend income is recorded on the ex-dividend date for dividends received in cash and/or securities. However, if the ex-dividend date has passed, certain dividends from foreign securities are recorded as the Portfolio is informed of the ex-dividend date. Interest income is recorded on the accrual basis. C Income Taxes -- The Portfolio is treated as a partnership for federal tax purposes. No provision is made by the Portfolio for federal or state taxes on any taxable income of the Portfolio because each investor in the Portfolio is ultimately responsible for the payment of any taxes on its share of taxable income. Since the Portfolio's investors include regulated investment companies that invest all or substantially all of their assets in the Portfolio, the Portfolio normally must satisfy the applicable source of income and diversification requirements (under the Internal Revenue Code) in order for its investors to satisfy them. The Portfolio will allocate at least annually among its investors each investor's distributive share of the Portfolio's net investment income, net realized capital gains, and any other items of income, gain, loss, deduction or credit. D Financial Futures Contract -- Upon entering a financial futures contract, the Portfolio is required to deposit either in cash or securities an amount (initial margin) equal to a certain percentage of the purchase price indicated in the financial futures contract. Subsequent payments are made or received by the Portfolio (margin maintenance) each day, dependent on daily fluctuations in the value of the underlying security, and are recorded for book purposes as unrealized gains or losses by the Portfolio. The Portfolio's investment in financial futures contracts is designed to hedge against anticipated future changes in price of current or anticipated Portfolio positions. Should prices move unexpectedly, the Portfolio may not achieve the anticipated benefits of the financial futures contracts and may realize a loss. E Put Options -- Upon the purchase of a put option by the Portfolio, the premium paid is recorded as an investment, the value of which is marked-to-market daily. When a purchased option expires, the Portfolio will realize a loss in the amount of the cost of the option. When the Portfolio enters into a closing sale transaction, the Portfolio will realize a gain or loss depending on whether the sales proceeds from the closing sale transaction are greater or less than the cost of the option. When the Portfolio exercises a put option, settlement is made in cash. The risk associated with purchasing options is limited to the premium originally paid. F Securities Sold Short -- The Portfolio may sell a security short if it owns at least an equal amount of the security sold short or another security convertible or exchangeable for an equal amount of the security sold short. Such transactions are done in anticipation of a decline in the market price of the securities or in order to hedge portfolio positions. The Portfolio will generally borrow the security sold in order to make delivery to the buyer. Upon executing the transaction, the Portfolio records the proceeds as deposits with brokers in the Statement of Assets and Liabilities and establishes an offsetting payable for securities sold short for the securities due on settlement. The proceeds 17 <Page> TAX-MANAGED SMALL-CAP VALUE PORTFOLIO AS OF APRIL 30, 2003 NOTES TO FINANCIAL STATEMENTS (UNAUDITED) CONT'D are retained by the broker as collateral for the short position. The liability is marked-to-market and the Portfolio is required to pay the lending broker any dividend or interest income earned while the short position is open. A gain or loss is recorded when the security is delivered to the broker. The Portfolio may recognize a loss on the transaction if the market value of the securities sold increases before the securities are delivered. G Foreign Currency Translation -- Investment valuations, other assets and liabilities initially expressed in foreign currencies are converted each business day into U.S. dollars based upon current exchange rates. Purchases and sales of foreign investment securities and income and expenses are converted into U.S. dollars based upon currency exchange rates prevailing on the respective dates of such transactions. Recognized gains or losses on investment transactions attributable to 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. H Expense Reduction -- Investors Bank & Trust Company (IBT) serves as custodian of the Portfolio. Pursuant to the custodian agreement, IBT receives a fee reduced by credits which are determined based on the average daily cash balances the Portfolio maintains with IBT. All significant credit balances used to reduce the Portfolio's custodian fees are reported as a reduction of expenses on the Statement of Operations. I 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. J Other -- Investment transactions are accounted for on a trade-date basis. K Interim Financial Statements -- The interim financial statements relating to April 30, 2003 and for the six months then ended have not been audited by independent certified public accountants, but in the opinion of the Portfolio's management reflect all adjustments, consisting only of normal recurring adjustments, necessary for the fair presentation of the financial statements. 2 Investment Adviser Fee and Other Transactions with Affiliates - ------------------------------------------- The investment adviser fee is earned by Boston Management and Research (BMR), a wholly-owned subsidiary of Eaton Vance Management (EVM), as compensation for management and investment advisory services rendered to the Portfolio. Under the advisory agreement, BMR receives a monthly advisory fee in the amount of 1.00% annually of average daily net assets of the Portfolio up to $500 million, and at reduced rates as daily net assets exceed that level. For the six months ended April 30, 2003, the advisory fee amounted to $114,019. Pursuant to a sub-advisory agreement, BMR has delegated the investment management of the Portfolio to Fox Asset Management LLC (Fox), a majority-owned subsidiary of EVM. BMR pays Fox a monthly fee for sub-advisory services provided to the Portfolio in the amount of 0.75% annually of average daily net assets up to $500 million, and at reduced rates as daily net assets exceed that level. Except for Trustees of the Portfolio who are not members of EVM's or BMR's organization, officers and Trustees receive remuneration for their services to the Portfolio out of the investment adviser fee. Trustees of the Portfolio that are not affiliated with BMR 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 April 30, 2003, no significant amounts have been deferred. Certain officers and Trustees of the Portfolio are officers of the above organizations. 3 Investment Transactions - ------------------------------------------- Purchases and sales of investments, other than short-term obligations, aggregated $8,834,662 and $2,270,771, respectively, for the six months ended April 30, 2003. 4 Federal Income Tax Basis of Unrealized Appreciation (Depreciation) - ------------------------------------------- The cost and unrealized appreciation (depreciation) in value of the investments owned at April 30, 2003, as computed on a federal income tax basis, were as follows: <Table> AGGREGATE COST $24,665,223 ----------------------------------------------------- Gross unrealized appreciation $ 1,468,081 Gross unrealized depreciation (2,152,977) ----------------------------------------------------- NET UNREALIZED DEPRECIATION $ (684,896) ----------------------------------------------------- </Table> 18 <Page> TAX-MANAGED SMALL-CAP VALUE PORTFOLIO AS OF APRIL 30, 2003 NOTES TO FINANCIAL STATEMENTS (UNAUDITED) CONT'D 5 Financial Instruments - ------------------------------------------- The Portfolio may trade in financial instruments with off-balance sheet risk in the normal course of its investing activities to assist in managing exposure to various market risks. These financial instruments include written options, forward foreign currency exchange contracts and financial futures 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 Portfolio 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. The Portfolio did not have any open obligations under these financial instruments at April 30, 2003. 6 Line of Credit - ------------------------------------------- The Portfolio participates with other portfolios and funds managed by BMR and EVM and its affiliates in a $150 million unsecured line of credit agreement with a group of banks. Borrowings will be made by the Portfolio solely to facilitate the handling of unusual and/or unanticipated short-term cash requirements. Interest is charged to each participating portfolio or fund based on its borrowings at an amount above either the Eurodollar rate or Federal Funds rate. In addition, a fee computed at an annual rate of 0.10% on the daily unused portion of the line of credit is allocated among the participating portfolios and funds at the end of each quarter. The Portfolio did not have any significant borrowings or allocated fees for the six months ended April 30, 2003. 19 <Page> INVESTMENT MANAGEMENT EATON VANCE TAX-MANAGED SMALL-CAP VALUE FUND Officers Thomas E.
