FAUST] Thomas E. Faust President Eaton Vance Strategic Income Fund Class A shares had a total return of 16.65% during the year ended October 31, 2003. That return was the result of an increase in net asset value (NAV) per share from $7.55 on October 31, 2002 to $8.10 on October 31, 2003, and the reinvestment of $0.669 in dividends.(1) The Fund's Class B shares had a total return of 15.61% during the year ended October 31, 2003. That return resulted from an increase in NAV per share from $7.15 on October 31, 2002 to $7.66 on October 31, 2003, and the reinvestment of $0.576 in dividends.(1) Class C shares had a total return of 15.68% for the year ended October 31, 2003, the result of an increase in NAV per share from $9.04 on October 31, 2002 to $9.69 on October 31, 2003, and the reinvestment of $0.728 in dividends.(1) A STRONGER ECONOMY BROUGHT CHANGES IN THE GLOBAL BOND MARKETS IN 2003... The world's bond markets were characterized by widely divergent performance in 2003. As the U.S. economy showed signs of recovery, the Federal Reserve - which had lowered interest rates on thirteen occasions between January 2001 and June 2003 for a total of 550 basis points (5.50%) - indicated that it was less concerned about the possibility of deflation. The stronger economic news brought about a correction in the Treasury market. The U.S. high-yield market, however, responded favorably to a more robust economy and improving corporate profits. As a result, yield spreads over U.S. Treasuries for both high-yield corporate bonds and for investment-grade corporate bonds decreased significantly. Meanwhile, the emerging markets continued to fluctuate. An impressive economic recovery took hold in Asia, while countries in Eastern Europe and Latin America continued to work on economic reforms. ONCE AGAIN, THE GLOBAL MARKETS SAW CHALLENGES AND OPPORTUNITIES... The past year once again demonstrated the challenges and opportunities in the global markets. Fixed-income markets played a major role in capital formation for emerging economies, while providing strong returns in the U.S. corporate sector. The ability to participate in these diverse domestic and foreign markets is a key to Strategic Income Fund's flexibility. We believe that 2004 will bring more such opportunities. In the pages that follow, portfolio manager Mark Venezia provides his thoughts on the Fund and the markets in the fiscal year ended October 31, 2003. Sincerely, /s/ Thomas E. Faust Jr. Thomas E.

VENEZIA] Mark S. Venezia Portfolio Manager AN INTERVIEW WITH MARK S. VENEZIA, PORTFOLIO MANAGER OF STRATEGIC INCOME PORTFOLIO. Q: MARK, THE PAST FISCAL PERIOD WAS ANOTHER EVENTFUL YEAR IN THE GLOBAL BOND MARKETS. IN YOUR VIEW, WHAT WERE SOME OF THE MOST NOTABLE DEVELOPMENTS THAT DROVE THE MARKETS IN 2003? A: 2003 has been a transition year for the global economy. The U.S. economy has showed convincing early signs of a recovery. While stronger data kept the Treasury and mortgage-backed securities markets on the defensive for much of the period, it drove a strong rally in the high-yield corporate sector. In Japan and Asia, economies gathered strength, with currency issues increasingly prominent in U.S.-Asia trade talks. In Latin America, Brazil fared well, as the da Silva government made progress on social security reforms and inflation. Eastern Europe economies continued their strong expansion, while making further progress on their reform packages. Thus, differentiation between markets was the key to performance during the fiscal year. Q: WHAT IMPACT HAS THE FEDERAL RESERVE'S POSTURE HAD ON THE BOND MARKETS? A: The Federal Reserve has maintained an accommodative interest rate policy for three years running. Even as the economy has rebounded in the second half of 2003, the Fed refrained from raising rates. While that posture has helped ease the nation's economy out of recession, it has also contributed to a weaker U.S. dollar versus the euro. Europe's recovery has lagged that of the U.S., the European Central Bank having taken a more passive attitude toward interest rates. Those trends make managing foreign currency positions more challenging for global investors. As demand increases and inflationary pressures build, the Fed will surely be forced at some point to raise rates. Such a move would likely reverse the dollar's decline against the euro. Q: HOW HAVE YOU REPOSITIONED THE FUND OVER THE LAST YEAR? A: First we've moved the duration from a relatively low level of just under three years, to an even lower level of about two years. This reflects our optimism about the U.S. economy, which, week by week is turning into pessimism about inflation. Going one step further, we're even heavier into seasoned mortgage-backed securities than we were a year ago. Then, we were a bit under 60%, now nearly 70%. If interest rates in the middle of the curve just steady in the 3.25% to FOREIGN POSITIONS By total net assets. Positions are in Local Currency unless otherwise noted. <Table> Indonesia** 5.9% Hungary 4.1 Slovakia 3.9 Brazil* 3.1 India 1.8 Colombia 1.6 Thailand 1.0 Taiwan 0.9 South Korea 0.9 Poland 0.3 Morocco* 0.2 Phillippines* 0.1 </Table> *Positions are in Hard Currency. **Position is in Local Currency and Hard Currency. 3 <Page> 4.25% range, refinancings should drop on these premium bonds. The mortgage-backed securities that we buy are typically ten years or more old, so the home owners that are left are far and few between; we believe that those who had a lot of equity to take out of their homes, have done so already. Q: WHAT ABOUT YOUR POSITIONS IN THE HIGH-YIELD SECTOR? A: Looking at end of year reports you'd get the impression that we've only increased these bonds from about 24% to 28% of the Fund. In fact, we did reach levels over 30% during the year, but now we're pulling back a bit because spreads over Treasuries have come way in. When markets were still reacting to the defaults of 2001-2002, last October, spreads were 1000 basis points (10%) over Treasuries. Now they're less than half of that. Q: WHAT ABOUT EMERGING MARKETS? HAVE YOU PARED DOWN POSITIONS? A: We've pared down our positions in the dollar bond sector, only to replace it with currency positions. Let me explain. The rally in the traditional Brady and global bonds of once defaulting countries such as Russia and Brazil, worked in parallel with the rally in our local high yield sector; indeed it was even more dramatic. Last October we had already brought these positions down to about 12% percent of the Fund; as the rally gathered momentum we cut these positions further and further, down to just over 3% of net assets. However, the last frontier of emerging markets are the local markets of these countries, where one can take advantage of high interest rates and undervalued currencies. At fiscal year's close, we had nearly 20% of the Fund in these foreign currency positions; the largest were Indonesia with 5.4% and Slovakia with 3.9%. It should be noted that most of these positions were in what are called "currency forwards", i.e., agreements to buy the currencies for delivery a number of months from the trade date, usually at a substantial discount. We often cross-hedge these positions with another currency from the same region, so that our regional exposure is kept to what we believe to be manageable levels. Q: THE FUND POSTED A STRONG RETURN DURING THE FISCAL YEAR. TO WHAT DO YOU ATTRIBUTE THE FUND'S PERFORMANCE? A: The net asset value of the Fund rose by nearly 9% from last October to the middle of June 2003. This was the period of the extraordinary rally in the high yield and dollar denominated emerging market sectors, when spreads compressed by about 500 basis points (5.0%). We had between 30% and 40% of the Fund invested in these sectors during that period. Q: WERE THERE ANY AREAS THAT PERFORMED POORLY FOR THE FUND? A: Yes. Mortgage-backed securities (MBS) had a difficult year. The primary reason for the sector's underperformance was the sharp rise in prepayment rates. Prepay rates rose as homeowners refinanced their mortgages to take advantage of the lowest interest rates in 45 years. While it's not unusual to see rising prepayment rates accompany lower interest rates, the surge of refinancings during this period was remarkable. The increase was evident not only among generic MBS, but also among seasoned MBS, which have historically displayed much more predictable prepayment rates. While this was a challenging period for the mortgage market, we believe that, at this point in the economic cycle, interest rates have likely bottomed. Accordingly, we would expect that prepayment rates would ease over time, providing a better climate for MBS investments. 4 <Page> Q: MARK, HOW WOULD YOU CHARACTERIZE THIS PAST YEAR IN THE GLOBAL BOND MARKETS? A: I believe that this fiscal year once again pointed out the value of a broadly diversified bond portfolio. As we've seen, even in a global economy, different countries continued to move within their own regional economic cycles. As a result, opportunities may be emerging in some countries, even as other markets are retrenching. In the increasingly fluid global bond markets, the flexibility of a vehicle like Strategic Income Fund - with its latitude to move between countries and sectors, exploit changing currency and spread relationships, and adopt a variety of hedging techniques to manage risk - can be especially valuable.

The chart compares the Fund's total return with that of the Lehman Aggregate Bond Index, an unmanaged, broad-based index containing only investment-grade, fixed-income securities traded in the U.S. Securities in the Index are included without regard to their duration. The lines on the chart represent the total returns of $10,000 hypothetical investments in the Fund and the Index. Returns are calculated by determining the percentage change in net asset value (NAV) with all distributions reinvested. The chart also offers a comparison with a Composite of Lipper Fund Category averages, reflecting the average total returns of the funds in the same categories as this Fund. The fund categories are established by Lipper, Inc., a nationally recognized monitor of mutual fund performance. Funds within a category have similar investment policies. The Composite is provided because the Fund amended its investment policies on March 1, 1997, allowing the Fund to invest in a portfolio with a dollar-weighted average maturity of any duration. In connection with this change, the Fund's Lipper category also changed. Reflecting that change, the performance of a Composite is based on the Lipper Short World Multi-Market Income Funds Classification from October 31, 1991 through March 1, 1997, and thereafter, on the Lipper Multi-Sector Income Funds Classification. An investment in the Fund's Class A shares on 1/23/98 at net asset value would have been worth $13,665 on October 31, 2003; $13,015 including the 4.75% sales charge. An investment in the Fund's Class C shares on 5/25/94 at net asset value would have been worth $19,239 on October 31, 2003. The graph and performance table do not reflect the deduction of taxes that a shareholder would pay on Fund distributions or the redemption of Fund shares. The Index's and Composite's total returns do not reflect commissions or expenses that would have been incurred if an investor individually purchased or sold the securities represented in the Index. It is not possible to invest directly in an Index or a Composite. ** Returns are historical and are calculated by determining the percentage change in net asset value with all distributions reinvested. SEC returns for Class A reflect the maximum 4.75% sales charge. SEC returns for Class B 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. SEC 1-year return for Class C reflects 1% CDSC. 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.

THESE VIEWS ARE SUBJECT TO CHANGE AT ANY TIME BASED UPON MARKET OR OTHER CONDITIONS, AND EATON VANCE DISCLAIMS ANY RESPONSIBILITY TO UPDATE SUCH VIEWS. THESE VIEWS MAY NOT BE RELIED ON AS INVESTMENT ADVICE AND, BECAUSE INVESTMENT DECISIONS FOR AN EATON VANCE FUND ARE BASED ON MANY FACTORS, MAY NOT BE RELIED ON AS AN INDICATION OF TRADING INTENT ON BEHALF OF ANY EATON VANCE FUND. 5 <Page> EATON VANCE STRATEGIC INCOME FUND AS OF OCTOBER 31, 2003 FINANCIAL STATEMENTS STATEMENT OF ASSETS AND LIABILITIES AS OF OCTOBER 31, 2003 <Table> ASSETS Investment in Strategic Income Portfolio, at value (identified cost, $278,453,943) $ 277,081,103 Investment in High Income Portfolio, at value (identified cost, $61,596,184) 63,839,001 Receivable for Fund shares sold 1,624,876 -

See notes to financial statements. 10 <Page> EATON VANCE STRATEGIC INCOME FUND AS OF OCTOBER 31, 2003 NOTES TO FINANCIAL STATEMENTS 1 SIGNIFICANT ACCOUNTING POLICIES Eaton Vance Strategic Income Fund (the Fund) is a non-diversified series of Eaton Vance Mutual Funds Trust (the Trust). The Fund 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 the 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). 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 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. Net investment income, other than class specific expenses, is allocated daily to each class of shares based upon the ratio of the value of each class' paid shares to the total value of all paid shares. Each class of shares differs in its distribution plan and certain other class specific expenses. The Fund currently invests all of its investable assets in interests in two Portfolios, Strategic Income Portfolio and High Income Portfolio (the Portfolios), New York trusts which have investment objectives consistent with that of the Fund. The value of the Fund's investment in the Portfolios reflects the Fund's proportionate interest in the net assets of the Strategic Income Portfolio and the High Income Portfolio (99.9% and 5.5% at October 31, 2003, respectively). The performance of the Fund is directly affected by the performance of the Portfolios. The financial statements of the Strategic Income Portfolio, including the portfolio of investments, are included elsewhere in this report and should be read in conjunction with the Fund's financial statements. See Note 8 for further information on the results of operations of High Income Portfolio. A copy of the financial statements of High Income Portfolio is available on the EDGAR Database on the Securities and Exchange Commission's website (www.sec.gov), at the Commission's public reference room in Washington, DC or upon request from the Fund's principal underwriter, Eaton Vance Distributors Inc. (EVD) by calling 1-800-225-6265. 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 Strategic Income Portfolio is discussed in Note 1A of the Portfolio's Notes to Financial Statements, which are included elsewhere in this report. High Income Portfolio's valuation policies are as follows: Fixed income investments (other than short-term obligations), including listed investments and investments for which price quotations are available, will normally be valued on the basis of market valuations furnished by a pricing service. Marketable securities 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. Listed or unlisted investments for which closing sale prices are not available are valued at the mean between the latest bid and ask prices. Financial futures contracts listed on commodity exchanges are valued at closing settlement prices. Short-term obligations, maturing in sixty days or less, are valued at amortized cost, which approximates value. Investments for which there are no quotations or valuations are valued at fair value using methods determined in good faith by or at the direction of the Trustees. B INCOME -- The Fund's net investment income consists of the Fund's pro rata share of the net investment income of the Portfolios, less all actual and accrued expenses of the Fund determined in accordance with accounting principles generally accepted in the United States of America. C 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 taxable income, including any net realized gain on investments. Accordingly, no provision for Federal income or excise tax is necessary. At October 31, 2003, the Fund, for Federal income tax purposes, had a capital loss carryover of $35,214,191 which will reduce the Fund's taxable income arising from future net realized gains on investments, if any, to the extent permitted by the Internal Revenue Code, and thus will reduce the amount of the distributions to shareholders which would otherwise be necessary to relieve the Fund of any liability for federal income or excise tax. Such capital loss carryover will expire on October 31, 2006 ($1,984,147), October 31, 2007 ($7,933,008), October 31, 2009 ($9,854,300), October 31, 2010 ($14,208,464) and October 31, 2011 ($1,234,272). The amount of the tax basis capital loss carryforward differed from the accumulated net realized loss due primarily to the timing of recording gain/loss on certain futures contracts. At October 31, 2003, the undistributed ordinary income on a tax basis was $3,341,979. All distributions in the year ended October 31, 2003 were from ordinary income for tax purposes. 11 <Page> D 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. E 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. 2 DISTRIBUTIONS TO SHAREHOLDERS The net income of the Fund is determined daily and substantially all of the net income so determined is declared as a dividend to shareholders of record at the time of declaration. Distributions are paid monthly. Distributions of allocated realized capital gains, if any, are made at least annually. Shareholders may reinvest income and capital gain distributions in additional shares of the Fund at the net asset value as of the ex-dividend date. Distributions are paid in the form of additional shares or, at the election of the shareholder, in cash. 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. Differences between book and tax accounting relating to distributions primarily relate to futures, swaps, and foreign currency transactions; difference in method for amortizing premiums, accreting certain discounts and recognizing distributions to shareholders; treatment of paydown losses; and expired capital loss carryforwards. 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> YEAR ENDED OCTOBER 31, --------------------------- CLASS A 2003 2002 ------------------------------------------------------------------------------------- Sales 4,600,754 1,831,820 Issued to shareholders electing to receive payments of distributions in Fund shares 142,606 71,825 Redemptions (1,028,743) (1,135,544) ------------------------------------------------------------------------------------- NET INCREASE 3,714,617 768,101 ------------------------------------------------------------------------------------- <Caption> YEAR ENDED OCTOBER 31, --------------------------- CLASS B 2003 2002 ------------------------------------------------------------------------------------- Sales 8,645,301 6,568,813 Issued to shareholders electing to receive payments of distributions in Fund shares 639,463 522,773 Redemptions (5,228,731) (4,259,717) ------------------------------------------------------------------------------------- NET INCREASE 4,056,033 2,831,869 ------------------------------------------------------------------------------------- <Caption> YEAR ENDED OCTOBER 31, --------------------------- CLASS C 2003 2002 ------------------------------------------------------------------------------------- Sales 3,953,399 1,722,079 Issued to shareholders electing to receive payments of distributions in Fund shares 217,482 183,562 Redemptions (1,544,901) (1,521,743) ------------------------------------------------------------------------------------- NET INCREASE 2,625,980 383,898 ------------------------------------------------------------------------------------- </Table> 4 INVESTMENT ADVISER FEE AND OTHER TRANSACTIONS WITH AFFILIATES Eaton Vance Management (EVM) serves as the administrator of the Fund, but receives no compensation. The Portfolios have engaged Boston Management and Research (BMR), a subsidiary of EVM, to render investment advisory services. See Note 2 of each of the Portfolio's Notes to financial statements. Except as to Trustees of the Fund and the Portfolios who are not members of EVM's organization, officers and Trustees receive remuneration for their services to the Fund out of such investment adviser fee. Certain officers and Trustees of the Fund and of the Portfolios are officers of the above organizations (see Note 5). EVM serves as the sub-transfer agent of the Fund and receives an aggregate fee based upon the actual expenses incurred by EVM in the performance of those services. 12 <Page> During the year ended October 31, 2003, EVM earned $21,111 in sub-transfer agent fees. The Fund was informed that Eaton Vance Distributors, Inc. (EVD), a subsidiary of EVM and the Fund's principal underwriter, received $30,550 as its portion of the sales charge on sales of Class A shares for the year ended October 31, 2003. 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) 5% and 6.25% of the aggregate amount received by the Fund for Class B and Class C shares sold, respectively, plus (ii) interest calculated by applying the rate of 1% over the prevailing prime rate to the outstanding balance of Uncovered Distribution Charges due EVD, of each respective class reduced by the aggregate amount of contingent deferred sales charges (see Note 6) and daily amounts theretofore paid to EVD by each respective class. The amount payable to EVD with respect to each day is accrued on such day as a liability of the Fund and, accordingly, reduces the Fund's net assets. For the year ended October 31, 2003, the Fund paid or accrued $1,459,539 and $419,767, respectively, to or payable to EVD representing 0.75% of average daily net assets of Class B and Class C shares, respectively. At October 31, 2003, the amount of Uncovered Distribution Charges of EVD calculated under the Plans was approximately $31,866,000 and $6,105,000 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 not exceeding 0.25% of the Fund's average daily net assets attributable to Class A, Class B, and Class C shares for the fiscal year. Service fee payments will be made for personal services and/or the maintenance of shareholder accounts. Service fees are separate and distinct from the sales and 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 year ended October 31, 2003 amounted to $70,077, $486,513, and $139,923 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 on the lower of the net asset value at the date of redemption or date of purchase. No charge is levied on shares acquired by reinvestment of dividends or capital gains distributions. The Class B CDSC is imposed at declining rates that begin at 5% in the case of redemptions in the first and second years of redemption 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 charges are paid to EVD to reduce the amount of Uncovered Distribution Charges calculated under the Fund's Distribution Plans. CDSC charges received when no Uncovered Distribution Charges exist will be credited to the Fund. The Fund has been informed that EVD received approximately $629,000 and $11,000 of CDSC paid by shareholders of Class B and Class C shares, respectively, during the year ended October 31, 2003. 7 INVESTMENT TRANSACTIONS Increases and decreases in the Fund's investment in the Strategic Income Portfolio for the year ended October 31, 2003, aggregated $139,366,724 and $78,107,725, respectively. There were no increases or decreases in the Fund's investment in the High Income Portfolio for the year ended October 31, 2003. 13 <Page> 8 INVESTMENT IN PORTFOLIOS For the year ended October 31, 2003, the Fund was allocated net investment income and realized and unrealized gain (loss) from the Portfolios as follows: <Table> <Caption> STRATEGIC HIGH INCOME INCOME PORTFOLIO PORTFOLIO TOTAL -------------------------------------------------------------------------------------- Interest income $ 9,112,876 $ 5,847,647 $ 14,960,523 Dividend income -- 125,175 125,175 Expenses (1,598,338) (367,792) (1,966,130) -------------------------------------------------------------------------------------- NET INVESTMENT INCOME $ 7,514,538 $ 5,605,030 $ 13,119,568 -------------------------------------------------------------------------------------- Net realized gain (loss) -- Investment transactions $ 5,872,776 $ 2,229,859 $ 8,102,635 Financial futures contracts (1,037,192) -- (1,037,192) Written options 251,687 -- 251,687 Swap contracts 4,292,036 -- 4,292,036 Foreign currency and forward foreign currency exchange contracts (329,638) (66,450) (396,088) -------------------------------------------------------------------------------------- NET REALIZED GAIN (LOSS) $ 9,049,669 $ 2,163,409 $ 11,213,078 -------------------------------------------------------------------------------------- Change in unrealized appreciation (depreciation) Investments $ 7,316,866 $ 8,669,330 $ 15,986,196 Financial futures contracts (538,824) -- (538,824) Written options 85,812 -- 85,812 Swap contracts 839,871 -- 839,871 Foreign currency and forward foreign currency exchange contracts 1,101,542 7,720 1,109,262 -------------------------------------------------------------------------------------- NET CHANGE IN UNREALIZED APPRECIATION (DEPRECIATION) $ 8,805,267 $ 8,677,050 $ 17,482,317 -------------------------------------------------------------------------------------- </Table> 9 SHAREHOLDER MEETING (UNAUDITED) The Fund held a Special Meeting of Shareholders on June 6, 2003 to elect Trustees.

Additionally, the Portfolio reclassified net losses realized on prepayments received on mortgage-backed securities that were previously included in realized gains/losses to interest income. The effect of these changes for the year ended October 31, 2002 was a decrease in the ratio of net investment income to average net assets from 7.32% to 5.88%. Ratios for the periods prior to October 31, 2001 have not been restated to reflect this change in presentation.

See notes to financial statements. 21 <Page> STRATEGIC INCOME PORTFOLIO AS OF OCTOBER 31, 2003 NOTES TO FINANCIAL STATEMENTS 1 SIGNIFICANT ACCOUNTING POLICIES Strategic Income Portfolio (the Portfolio) is registered under the Investment Company Act of 1940 as a non-diversified open-end investment company. The Portfolio, which was organized as a trust under the laws of the State of New York in 1992, seeks to achieve a high level of income by investing in a global portfolio consisting primarily of high grade debt securities. The Declaration of Trust permits the Trustees to issue beneficial interests in the Portfolio. At October 31, 2003, Eaton Vance Strategic Income Fund held an approximate 99.9% interest in the Portfolio. The following is a summary of significant accounting policies of the Portfolio. The policies are in conformity with accounting principles generally accepted in the United States of America. A INVESTMENT VALUATION -- Seasoned mortgage backed, pass-through securities are valued using an independent matrix pricing system applied by the advisor which takes into account closing bond valuations, yield differentials, anticipated prepayments and interest rates provided by dealers. Debt securities (other than seasoned mortgage-backed, pass-through securities and short-term obligations maturing in sixty days or less), including listed securities and securities for which price quotations are available and forward contracts, will normally be valued on the basis of market valuations furnished by pricing services. Marketable securities 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 valued at the mean between the latest available bid and ask prices. For foreign investments, if trading or events occurring in other markets after the close of the principal exchange in which the securities are traded are expected to materially affect the value of the investments, then those investments are valued, taking into consideration these events, at their fair value following procedures approved by the Trustees. Financial futures contracts listed on commodity exchanges and exchange-traded options are valued at closing settlement prices. Short-term obligations and money-market securities maturing in sixty days or less are valued at amortized cost which approximates value. Non-U.S. dollar denominated short-term obligations are valued at amortized cost as calculated in the base currency and translated to U.S. dollars at the current exchange rate. Investments for which 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 -- Interest income is determined on the basis of interest accrued and discount earned, adjusted for amortization of premium or accretion of discount. 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. Dividend income may include dividends that represent returns of capital for federal income tax purposes. C GAINS AND LOSSES FROM INVESTMENT TRANSACTIONS -- Realized gains and losses from investment transactions are recorded on the basis of identified cost. For book purposes, gains and losses are not recognized until disposition. For federal tax purposes, the Portfolio is subject to special tax rules that may affect the amount, timing and character of gains recognized on certain of the Portfolio's investments. D 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. Since at least one of the Portfolio's investors is a regulated investment company that invests all or substantially all of its 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. Withholding taxes on foreign dividends and capital gains have been provided for in accordance with the Portfolio's understanding of the applicable countries' tax rules and rates. E FINANCIAL FUTURES CONTRACTS -- Upon entering into a financial futures contract, the Portfolio is required to deposit an amount (initial margin), either in cash or securities, equal to a certain percentage of the purchase price indicated in the financial futures contract. Subsequent payments are made or received by the Portfolio (variation margin) each day, dependent on the 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 for both hedging against anticipated future changes in interest or currency exchange rates and investment purposes. Should interest or currency exchange rates move 22 <Page> unexpectedly, the Portfolio may not achieve the anticipated benefits of the financial futures contracts and may realize a loss. If the Portfolio enters into a closing transaction, the Portfolio will realize, for book purposes, a gain or loss equal to the difference between the value of the financial futures contract to sell and financial futures contract to buy. F WHEN-ISSUED AND DELAYED DELIVERY TRANSACTIONS -- The Portfolio may engage in when-issued and delayed delivery transactions. The Portfolio records when-issued securities on trade date and maintains security positions such that sufficient liquid assets will be available to make payments for the securities purchased. Securities purchased on a when-issued or delayed delivery basis are marked-to-market daily and begin earning interest on settlement date. 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 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. H WRITTEN OPTIONS -- The Portfolio may write call or put options for which premiums are received and are recorded as liabilities, and are subsequently adjusted to the current value of the options written. Premiums received from writing options which expire are treated as realized gains. Premiums received from writing options which are exercised or closed are offset against the proceeds or amount paid on the transaction to determine the realized gain or loss. If a put option is exercised, the premium reduces the cost basis of the securities purchased by the Portfolio. The Portfolio as writer of an option may have no control over whether the underlying securities may be sold (call) or purchased (put) and as a result bears the market risk of an unfavorable change in the price of the securities underlying the written option. I FORWARD FOREIGN CURRENCY EXCHANGE CONTRACTS -- The Portfolio 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. 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. The Portfolio will 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 for financial statement purposes as unrealized until such time as the contracts have been closed. J REVERSE REPURCHASE AGREEMENTS -- The Portfolio may enter into reverse repurchase agreements. Under such an agreement, the Portfolio temporarily transfers possession, but not ownership, of a security to a counterparty, in return for cash. At the same time, the Portfolio agrees to repurchase the security at an agreed-upon price and time in the future. The Portfolio may enter into reverse repurchase agreements for temporary purposes, such as to fund withdrawals, or for use as hedging instruments where the underlying security is denominated in a foreign currency. As a form of leverage, reverse repurchase agreements may increase the risk of fluctuation in the market value of the Portfolio's assets or in its yield. Liabilities to counterparties under reverse repurchase agreements are recognized in the Statement of Assets and Liabilities at the same time at which cash is received by the Portfolio. The securities underlying such agreements continue to be treated as owned by the Portfolio and remain in the Portfolio of Investments. Interest charged on amounts borrowed by the Portfolio under reverse repurchase agreements is accrued daily. K TOTAL RETURN SWAPS -- The Portfolio may enter into swap agreements to enhance return, to hedge against fluctuations in securities prices or interest rates or as substitution for the purchase or sale of securities. Pursuant to these agreements, the Portfolio makes monthly payments at a rate equal to a predetermined spread to the one-month LIBOR. In exchange, the Portfolio receives payments based on the rate of return of a benchmark industry index. During the term of the outstanding swap agreement, changes in the underlying value of the swap are recorded as unrealized gains and losses. Payments received or made at the end of the measurement period are recorded as realized gains and losses. The value of the swap is determined by changes in the relationship between the rate of interest and the benchmark industry index. The Portfolio is exposed to credit loss in the event of non-performance by the swap counterparty. However, the Portfolio does not anticipate non-performance by the counterparty. Risk may also arise from the unanticipated movements in value of interest rates or the index. 23 <Page> L 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 balance the Portfolio maintains with IBT. All significant credits used to reduce the Portfolio's custodian fees are reported separately as a reduction of total expenses in the Statement of Operations. For the year ended October 31, 2003, $284 in credits were used to reduce the Portfolio's custodian fee. M 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. N OTHER -- Investment transactions are accounted for on a trade date basis. 2 INVESTMENT ADVISER FEE AND OTHER TRANSACTIONS WITH AFFILIATES The investment adviser fee is earned by Boston Management and Research (BMR), a subsidiary of Eaton Vance Management (EVM), as compensation for management and investment advisory services rendered to the Portfolio. The fee is based upon a percentage of average daily net assets plus a percentage of gross income (i.e., income other than gains from the sale of investments and paydown gains/losses). Such percentages are reduced as average daily net assets exceed certain levels. For the year ended October 31, 2003, the fee was equivalent to 0.47% of the Portfolio's average net assets for such period and amounted to $1,053,507. An administration fee, computed at an effective annual rate of 0.15% of average daily net assets was also paid to BMR for administrative services and office facilities. Such fee amounted to $335,533 for the year ended October 31, 2003. Except as to 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 such investment adviser fee. Trustees of the Portfolio that are not affiliated with the Investment Adviser may elect to defer receipt of all or a portion of their annual fees in accordance with the terms of the Trustees Deferred Compensation Plan. For the year ended October 31, 2003, no significant amounts have been deferred. Certain officers and Trustees of the Portfolio are officers of the above organizations. 3 LINE OF CREDIT The Portfolio participates with other portfolios and funds managed by BMR or 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 portfolio or fund based on its borrowings at an amount above 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 during the year ended October 31, 2003. 4 INVESTMENT TRANSACTIONS The Portfolio invests primarily in foreign government and U.S. Government debt securities. The ability of the issuers of the debt securities to meet their obligations may be affected by economic developments in a specific industry or country. The Portfolio regularly invests in lower rated and comparable quality unrated high yield securities. These investments have different risks than investments in debt securities rated investment grade and held by the Portfolio. Risk of loss upon default by the borrower is significantly greater with respect to such debt securities than with other debt securities because these securities are generally unsecured and are more sensitive to adverse economic conditions, such as recession or increasing interest rates, than are investment grade issuers. At October 31, 2003, the Portfolio had invested 6.74% of its net assets or approximately $18,700,000 in high yield securities. Purchases and sales of investments, other than short-term obligations, and including paydowns on mortgage backed securities, for the year ended October 31, 2003 were as follows: <Table> PURCHASES Investments (non-U.S. Government) $ 18,374,699 U.S. Government Securities 206,077,687 --------------------------------------------------- $ 224,452,386 --------------------------------------------------- SALES Investments (non-U.S. Government) $ 50,801,352 U.S. Government Securities 99,056,190 --------------------------------------------------- $ 149,857,542 --------------------------------------------------- </Table> 24 <Page> 5 FINANCIAL INSTRUMENTS The Portfolio regularly trades in financial instruments with off-balance sheet risk in the normal course of its investing activities and to assist in managing exposure to various market risks. These financial instruments include written options, forward foreign currency contracts, financial futures contracts and swaps 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. A summary of obligations under these financial instruments at October 31, 2003 is as follows: <Table> <Caption> NET UNREALIZED SETTLEMENT DATES DELIVER IN EXCHANGE FOR APP/DEP. ---------------------------------------------------------------------------------- 1/28/04 Czech Republic Koruna United States Dollar 173,417,000 6,134,312 $ (139,344) 11/03/03 - 9/20/04 Euro Dollar United States Dollar 21,600,000 24,942,051 (88,020) 1/15/04 Euro Dollar Hungarian Forint 5,365,333 1,451,430,000 152,780 11/26/03 Euro Dollar Slovakia Koruna 5,700,000 241,281,000 127,173 9/27/04 Hong Kong Dollar United States Dollar 50,400,000 6,514,153 14,436 11/25/03 Japanese Yen United States Dollar 1,083,600,000 9,841,604 (59,728) 11/21/03 Mexican Peso United States Dollar 35,000,000 3,085,468 (76,990) - --------------------------------------------------------------------------------------- $ (69,693) - --------------------------------------------------------------------------------------- <Caption> NET UNREALIZED SETTLEMENT DATES IN EXCHANGE FOR DELIVER APP/DEP. ----------------------------------------------------------------------------------- 11/12/03 Columbian Peso United States Dollar 16,000,000 5,463,529 $ 82,439 1/15/04 Euro Dollar Czech Republic Koruna 5,380,424 170,513,700 67,152 11/3/03 Euro Dollar United States Dollar 7,950,000 9,252,210 (16,695) 1/28/04 Hungarian Forint United States Dollar 1,485,594 6,136,282 368,524 12/8/03 - 1/30/04 Indonesian Rupiah United States Dollar 107,000,000,000 12,288,212 148,804 12/8/03 Indian Rupee United States Dollar 282,500,000 6,131,973 103,142 1/30/04 Korean Won United States Dollar 3,686,000,000 3,091,763 1,109 9/20/04 Slovakia Koruna United States Dollar 243,219,000 6,402,810 190,568 1/30/04 Taiwan United States Dollar 107,000,000 3,160,071 (2,773) 1/30/04 Thai Baht United States Dollar 130,000,000 3,235,843 22,180 ---------------------------------------------------------------------------------- $ 964,450 ---------------------------------------------------------------------------------- </Table> <Table> <Caption> WRITTEN CALL OPTIONS NUMBER OF CONTRACTS PREMIUMS ----------------------------------------------------------------- Outstanding, beginning of year 250 $ 251,688 ----------------------------------------------------------------- Options expired (250) (251,688) ----------------------------------------------------------------- Outstanding, end of year -- $ -- ----------------------------------------------------------------- </Table> FUTURES CONTRACTS <Table> <Caption> EXPIRATION NET UNREALIZED DATE(S) CONTRACTS POSITION DEPRECIATION ---------------------------------------------------------------------- 12/03 17 Japan Bond 10 year Short $ (311,625) 12/03 884 U.S. Treasury 5 year Note Short (1,889,155) ---------------------------------------------------------------------- $ (2,200,780) ---------------------------------------------------------------------- </Table> At October 31, 2003, the Portfolio had sufficient cash and/or securities to cover potential obligations arising from open futures and forward contracts, as well as margin requirements on open futures contracts. 25 <Page> The Portfolio has entered into a total return swap agreement with Credit Suisse First Boston International whereby the Portfolio makes monthly payments at a rate equal to the one-month LIBOR plus 0.05% on the notional amount of $10,000,000.
