GLOBAL GROWTH PORTFOLIO AS OF FEBRUARY 29, 2004
NOTES TO FINANCIAL STATEMENTS (Unaudited)

1  SIGNIFICANT ACCOUNTING POLICIES

   Global Growth Portfolio (formerly known as Information Age Portfolio) (the
   Portfolio) is registered under the Investment Company Act of 1940 as a
   diversified, open-end management investment company, which was organized as a
   trust under the laws of the State of New York on June 1, 1995. The Portfolio
   seeks to provide long-term capital growth by investing in a global and
   diversified portfolio of securities expected to grow in value. The
   Declaration of Trust permits the Trustees to issue interests in the
   Portfolio. At February 29, 2004 the Eaton Vance Global Growth Fund held an
   approximate 99.9% interest in the Portfolio. The following is a summary of
   the significant accounting policies of the Portfolio. The policies are in
   conformity with accounting principles generally accepted in the United States
   of America.

   A INVESTMENT VALUATIONS -- 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. Generally, trading in
   foreign securities is substantially completed each day at various times prior
   to the close of the Exchange. The values of these securities used in
   determining the net asset value of a Portfolio generally are computed as of
   such times. Occasionally, events affecting the value of foreign securities
   may occur between such times and the close of the Exchange which will not be
   reflected in the computation of a Portfolio's net asset value (unless the
   Portfolio deems that such events would materially affect its net asset value,
   in which case an adjustment would be made and reflected in such computation).
   The Portfolio may rely on an independent fair valuation service in making any
   such adjustments. Foreign securities and currency held by a Portfolio will be
   valued in U.S. dollars; such values will be computed by the custodian based
   on foreign currency exchange rate quotations supplied by an independent
   quotation service.

   B INCOME TAXES -- The Portfolio has elected to be 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 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.

   C FINANCIAL FUTURES CONTRACTS -- Upon the entering of a financial futures
   contract, the Portfolio is required to deposit (initial margin) either in
   cash or securities an amount 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
   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 only to
   hedge against anticipated future changes in interest or currency exchange
   rates. Should interest or currency exchange rates move unexpectedly, the
   Portfolio may not achieve the anticipated benefits of the financial futures
   contracts and may realize a loss.

   D OPTIONS ON FINANCIAL FUTURES -- Upon the purchase of a put option on
   foreign currency by the Portfolio, the premium paid is recorded as an
   investment, the value of which is marked-to-market daily. When the 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 sales transaction,
   the Portfolio will realize a gain or loss depending upon whether the sales
   proceeds from the closing sales 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.

                                       19
<Page>

   E 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. Realized 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 as of February 29,
   2004 and losses on investments that results from fluctuations in foreign
   currency exchange rates is not separately disclosed.

   F 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.

   G EXPENSE REDUCTION -- Investors Bank and 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 credit balances
   used to reduce the Portfolio's custodian fees are reported as a reduction of
   total expenses in the Statement of Operations.

   H USE OF ESTIMATES -- The preparation of the financial statements in
   conformity with accounting principles generally accepted in the United States
   of America requires management to make estimates and assumptions that affect
   the reported amounts of assets and liabilities at the date of the financial
   statements and the reported amounts of income and expense during the
   reporting period. Actual results could differ from those estimates.

   I INDEMNIFICATIONS -- Under the Portfolio's organizational documents, its
   officers and Trustees may be indemnified against certain liabilities and
   expenses arising out of the performance of their duties to the Portfolio.
   Interestholders in the Portfolio are jointly and severally liable for the
   liabilities and obligations of the Portfolio in the event that the Portfolio
   fails to satisfy such liabilities and obligations; provided, however, that,
   to the extent assets are available in the Portfolio, the Portfolio may, under
   certain circumstances, indemnify interestholders from and against any claim
   or liability to which such holder may become subject by reason of being or
   having been an interestholder in the Portfolio. Additionally, in the normal
   course of business, the Portfolio enters into agreements with service
   providers that may contain indemnification clauses. The Portfolio's maximum
   exposure under these arrangements is unknown as this would involve future
   claims that may be made against the Portfolio that have not yet occurred.

   J OTHER -- Investment transactions are accounted for on a trade-date basis.
   Dividend income is recorded on the ex-dividend date. 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.

   K INTERIM FINANCIAL STATEMENTS -- The interim financial statements relating
   to February 29, 2004 and for the six months then ended have not been audited
   by independent certified public accountants, but in the opinion of the
   Portfolios' 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), and Lloyd George
   Investment Management (Bermuda) Limited, an affiliate of EVM (the Advisers),
   as compensation for management and investment advisory services rendered to
   the Portfolio. Under the advisory agreement, the Advisers receive a monthly
   fee, divided equally between them, of 0.0625% (0.75% annually) of the average
   daily net assets of the Portfolio up to $500,000,000, and at reduced rates as
   daily net assets exceed that level. For the six months ended February 29,
   2004, the adviser fee was 0.75% (annualized) of average net assets for such
   period and amounted to $384,266. In addition, an administrative fee is earned
   by EVM for managing and administering the business affairs of the Portfolio.
   Under the administration agreement, EVM earns a monthly fee in the amount of
   1/48th of 1% (equal to 0.25% annually) of the average daily net assets of the
   Portfolio up to $500,000,000, and at reduced rates as daily

                                       20
<Page>

   net assets exceed that level. For the six months ended February 29, 2004, the
   administration fee was 0.25% (annualized) of average net assets for such
   period and amounted to $127,493. Except as to the Trustees of the Portfolio
   who are not members of the Advisers or EVM's organization, officers and
   Trustees receive remuneration for their services to the Portfolio out of such
   investment adviser and administrative fees.

   Trustees of the Portfolio that are not affiliated with the Advisers 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 February 29, 2004, 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 $74,577,335 and $89,620,874, respectively, for the six months
   ended February 29, 2004.

4  FEDERAL INCOME TAX BASIS OF UNREALIZED APPRECIATION (DEPRECIATION)

   The cost and unrealized appreciation (depreciation) in value of the
   investments owned at February 29, 2004, as computed on a federal income tax
   basis, are as follows:

<Table>
                                
   AGGREGATE COST                  $    84,669,915
   -----------------------------------------------
   Gross unrealized appreciation   $    12,136,776
   Gross unrealized depreciation        (2,552,322)
   -----------------------------------------------
   NET UNREALIZED APPRECIATION     $     9,584,454
   -----------------------------------------------
</Table>

   The unrealized appreciation on foreign currency was $2,141.

5  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 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 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.

6  FINANCIAL INSTRUMENTS

   The Portfolio regularly trades 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 may
   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 February 29, 2004.

7  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 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 facility is allocated among the participating funds and
   portfolios at the end of each quarter. The Portfolio did not have any
   significant borrowings or allocated fees during the six months ended February
   29, 2004.

8  NAME CHANGE

   Effective January 1, 2004, Information Age Portfolio changed its name to
   Global Growth Portfolio.
