(1)  The Portfolio adopted the provisions of the AICPA Audit and Accounting
     Guide for Investment Companies and began amortizing market premiums on
     fixed-income securities, excluding mortgage-backed securities, and
     accreting certain discounts using a different methodology. 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.

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:

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:

STRATEGIC INCOME PORTFOLIO AS OF OCTOBER 31, 2003
INDEPENDENT AUDITORS' REPORT

TO THE TRUSTEES AND INVESTORS OF STRATEGIC INCOME PORTFOLIO:

In our opinion, the accompanying statement of assets and liabilities, including
the portfolio of investments, and the related statements of operations and of
changes in net assets and the supplementary data present fairly, in all material
respects, the financial position of Strategic Income Portfolio (the "Portfolio")
at October 31, 2003, and the results of its operations, the changes in its net
assets, and the supplementary data for the periods presented, in conformity with
accounting principles generally accepted in the United States of America. These
financial statements and supplementary data (hereafter referred to as "financial
statements") are the responsibility of the Portfolio's management; our
responsibility is to express an opinion on these financial statements based on
our audits. We conducted our audits of these financial statements in accordance
with auditing standards generally accepted in the United States of America,
which require that we plan and perform the audit to obtain reasonable assurance
about whether the financial statements are free of material misstatement. An
audit includes examining, on a test basis, evidence supporting the amounts and
disclosures in the financial statements, assessing the accounting principles
used and significant estimates made by management, and evaluating the overall
financial statement presentation. We believe that our audits, which included
confirmation of securities at October 31, 2003 by correspondence with the
custodian and brokers, provide a reasonable basis for our opinion.
