TAX-MANAGED INTERNATIONAL GROWTH PORTFOLIO as of October 31, 2003

NOTES TO FINANCIAL STATEMENTS

1   SIGNIFICANT ACCOUNTING POLICIES

    Tax-Managed International Growth 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 June 22, 1998, seeks
    to achieve long-term after-tax returns by investing in a diversified
    portfolio of foreign equity securities. The Declaration of Trust permits the
    Trustees to issue interests in the Portfolio. At October 31, 2003, the Eaton
    Vance Tax-Managed International Growth Fund and the Eaton Vance Tax-Managed
    Equity Asset Allocation Fund held 65.5% and 34.3% interests in the
    Portfolio, respectively. 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. Over-the-counter options are normally valued
    at the mean between the latest bid and asked price. Investments for which
    valuations or market quotations are unavailable or are considered by the
    investment adviser to not reflect current market conditions 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 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.

    E 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 or offset.

    F EXPENSE REDUCTION -- Investors Bank & Trust Company (IBT) serves as
    custodian to 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.

                                       27
<Page>

    G 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.

    H 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 wholly-owned subsidiary of Eaton Vance Management (EVM), as
    compensation for management and investment advisory services rendered to the
    Portfolio. BMR receives a monthly advisory fee in the amount of 1.00%
    annually of the average daily net assets of the Portfolio up to $500 million
    and at reduced rates as daily net assets exceed that level. For the year
    ended October 31, 2003, the advisory fee amounted to $970,995. 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 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   INVESTMENT TRANSACTIONS

    Purchases and sales of investments, other than short-term obligations,
    aggregated $92,528,139 and $96,899,320, respectively, for the year ended
    October 31, 2003.

4   FEDERAL INCOME TAX BASIS OF INVESTMENTS

    The cost and unrealized appreciation (depreciation) in value of the
    investments owned at October 31, 2003, as computed on a federal income tax
    basis, were as follows:

<Table>
                                       
    AGGREGATE COST                        $ 94,973,105
    --------------------------------------------------
    Gross unrealized appreciation         $ 16,255,886
    Gross unrealized depreciation           (3,097,484)
    --------------------------------------------------
    NET UNREALIZED APPRECIATION           $ 13,158,402
    --------------------------------------------------
</Table>

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 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 October 31, 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 during
    the year ended October 31, 2003.

7   RISKS ASSOCIATED WITH FOREIGN INVESTMENTS

    Investing in securities issued by companies whose principal business
    activities are outside the United States may involve significant risks not
    present in domestic investments. For example, there is generally less
    publicly available information about foreign companies, particularly those
    not subject to the disclosure and reporting requirements of the U.S.
    securities laws. Foreign issuers are generally not bound by uniform
    accounting, auditing, and financial reporting requirements and standards of
    practice comparable to those applicable to domestic issuers. Investments in
    foreign securities also involve the risk of possible adverse changes in
    investment or exchange control regulations, expropriation or confiscatory
    taxation, limitation on the

                                       28
<Page>

    removal of funds or other assets of the Portfolio, political or financial
    instability or diplomatic and other developments which could affect such
    investments. Foreign stock markets, while growing in volume and
    sophistication, are generally not as developed as those in the United
    States, and securities of some foreign issuers (particularly those located
    in developing countries) may be less liquid and more volatile than
    securities of comparable U.S. companies. In general, there is less overall
    governmental supervision and regulation of foreign securities markets,
    broker-dealers and issuers than in the United States.

8   INTERESTHOLDER MEETING (UNAUDITED)

    The Portfolio held a Special Meeting of Interestholders on June 6, 2003 to
    elect Trustees. The results of the vote were as follows:

    a Trustee effective July 1, 2003 pursuant to the mandatory retirement policy
    of the Portfolio.

TAX-MANAGED INTERNATIONAL GROWTH PORTFOLIO as of October 31, 2003

INDEPENDENT AUDITORS' REPORT

TO THE TRUSTEES AND INVESTORS OF TAX-MANAGED INTERNATIONAL GROWTH PORTFOLIO:

We have audited the accompanying statement of assets and liabilities, including
the portfolio of investments, of Tax-Managed International Growth Portfolio (the
Portfolio) as of October 31, 2003, and the related statement of operations for
the year then ended, the statements of changes in net assets for the two years
then ended and the supplementary data for the years ended October 31, 2003 and
2002, and for the period from the start of business, July 23, 2001, to October
31, 2001. These financial statements and supplementary data are the
responsibility of the Portfolio's management. Our responsibility is to express
an opinion on these financial statements and supplementary data based on our
audits.

We conducted our audits in accordance with auditing standards generally accepted
in the United States of America. Those standards require that we plan and
perform the audit to obtain reasonable assurance about whether the financial
statements and supplementary data are free of material misstatement. An audit
includes examining, on a test basis, evidence supporting the amounts and
disclosures in the financial statements. Our procedures included confirmation of
securities held as of October 31, 2003 by correspondence with the custodian and
brokers; where replies were not received from brokers, we performed other
auditing procedures. An audit also includes assessing the accounting principles
used and significant estimates made by management, as well as evaluating the
overall financial statement presentation. We believe that our audits provide a
reasonable basis for our opinion.

In our opinion, such financial statements and supplementary data referred to
above present fairly, in all material respects, the financial position of the
Tax-Managed International Growth Portfolio as of October 31, 2003, the results
of its operations for the year then ended, the changes in its net assets and the
supplementary data for the respective stated periods in conformity with
accounting principles generally accepted in the United States of America.
