See notes to financial statements 19 <Page> SOUTH ASIA PORTFOLIO as of December 31, 2004 NOTES TO FINANCIAL STATEMENTS 1 SIGNIFICANT ACCOUNTING POLICIES South Asia Portfolio (the Portfolio) is registered under the Investment Company Act of 1940 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 January 18, 1994, seeks to achieve long-term capital appreciation by investing primarily in equity securities of companies in India and surrounding countries of the Indian sub-continent. The Declaration of Trust permits the Trustees to issue interests in the Portfolio. At December 31, 2004, the Eaton Vance Greater India 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 -- Securities listed on a U.S. securities exchange generally are valued at the last sale price on the day of valuation or, if no sales took place on such date, at the mean between the closing bid and asked prices therefore on the exchange where such securities are principally traded. Equity securities listed on the NASDAQ National Market System generally are valued at the official NASDAQ closing price. Unlisted or listed securities for which closing sales prices or closing quotations are not available are valued at the mean between the latest available bid and asked prices or, in the case of preferred equity securities that are not listed or traded in the over-the-counter market, by an independent pricing service. The value of preferred equity securities that are valued by a pricing service on a bond basis will be adjusted by an income factor, to be determined by the investment adviser, to reflect the next anticipated regular dividend. Exchange-traded options are valued at the last sale price for the day of valuation as quoted on the principal exchange or board of trade on which the options are traded or, in the absence of sales on such date, at the mean between the latest bid and asked prices therefore. Futures positions on securities and currencies generally are valued at closing settlement prices. Short-term debt securities with a remaining maturity of 60 days or less are valued at amortized cost. If short-term debt securities were acquired with a remaining maturity of more than 60 days, their amortized cost value will be based on their value on the sixty-first day prior to maturity. 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. The daily valuation of foreign securities generally is determined as of the close of trading on the principal exchange on which such securities trade. Events occurring after the close of trading on foreign exchanges may result in adjustments to the valuation of foreign securities to more accurately reflect their fair value as of the close of regular trading on the New York Stock Exchange. The Portfolio may rely on an independent fair valuation service in adjusting the valuations of foreign securities. Foreign securities and currencies are valued in U.S. dollars, based on foreign currency exchange rate quotations supplied by an independent quotation service. Investments held by the Portfolio 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 of the Portfolio considering relevant factors, data and information including the market value of freely tradable securities of the same class in the principal market on which such securities are normally traded. B FEDERAL 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 individually responsible for the payment of any taxes on its share of such income. Since some of the Portfolio's investors are 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. 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. In addition to the requirements of the Internal Revenue Code, the Portfolio may also be subject to capital gains tax in India on gains realized upon disposition of Indian securities, payable prior to repatriation of sales proceeds. The tax is computed on net realized gains; any realized losses in excess of gains may be carried forward to offset future gains. During the year ended December 31, 2004, the Portfolio made payments of tax subject to such requirement in the amount of $75,342. In addition, the Portfolio may accrue a deferred tax liability for net unrealized gains in excess of available carryforwards on Indian securities based on existing tax rates and anticipated holding periods of the securities. As of December 31, 2004, non-U.S. taxes provided on unrealized gains were zero. The Portfolio has recorded a receivable of $45,511 for provisional tax rebate for the Indian tax year ending March 31, 2005. 20 <Page> C FINANCIAL FUTURES CONTRACTS -- Upon entering into a financial futures contract, the Portfolio is required to deposit (initial margin) either cash or securities in 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 daily fluctuations in the value of the underlying security, and are recorded for book purposes as unrealized gains or losses by the Portfolio. 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. 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. 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. 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 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. 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 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 credit balances used to reduce the Portfolio's custodian fees are reported as a reduction of total expenses in the Statement of Operations. For the year ended December 31, 2004, there were no credit balances used to reduce the Portfolio's custodian fee. 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 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. I OTHER -- Investment transactions are accounted for on the date the securities are purchased or sold. 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. 2 INVESTMENT ADVISER FEE AND OTHER TRANSACTIONS WITH AFFILIATES The investment adviser fee is earned by Lloyd George Investment Management (Bermuda) Limited (the Adviser) as compensation for management and investment advisory services rendered to the Portfolio. Under the advisory agreement, the Adviser receives a monthly fee 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 21 <Page> net assets exceed that level. For the year ended December 31, 2004, the adviser fee was 0.75% of average daily net assets and amounted to $486,463. In addition, an administration fee is earned by Eaton Vance Management (EVM) for 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 net assets exceed that level. For the year ended December 31, 2004, the administration fee was 0.25% of average net assets and amounted to $162,241. Except as to Trustees of the Portfolio who are not members of the Adviser's or EVM's organization, officers and Trustees receive remuneration for their services to the Portfolio out of such investment adviser and administrative fees. Certain officers and Trustees of the Portfolio are officers of the above organizations. 3 INVESTMENT TRANSACTIONS For the year ended December 31, 2004, purchases and sales of investments, other than short-term obligations, aggregated $76,679,422 and $42,540,291, respectively. 4 FEDERAL INCOME TAX BASIS OF UNREALIZED APPRECIATION (DEPRECIATION) The cost and unrealized appreciation (depreciation) in value of the investments owned at December 31, 2004, as computed on a federal income tax basis, are as follows: <Table> AGGREGATE COST $ 63,847,083 - ------------------------------------------------------- Gross unrealized appreciation $ 28,888,311 Gross unrealized depreciation (33,866) - ------------------------------------------------------- NET UNREALIZED APPRECIATION $ 28,854,445 - ------------------------------------------------------- </Table> The appreciation on currency is $27,245. 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. Settlement of securities transactions in the Indian subcontinent may be delayed and is generally less frequent than in the United States, which could affect the liquidity of the Portfolio's assets. The Portfolio may be unable to sell securities where the registration process is incomplete and may experience delays in receipt of dividends. 6 INDIA TAXES The Portfolio is subject to certain Indian income taxes in connection with distributions from, and transactions in, Indian securities. The Indian tax authority has conducted a review of the Portfolio's tax returns filed for the years ended March 31, 2002 and 2001. In March 2004, the Indian tax authority assessed the Portfolio additional taxes for the 2000-2001 tax year and recalculated the refund owed to the Portfolio for the 2001-2002 tax year, a net assessment of approximately US $815,000. While the outcome of an appeal cannot be predicted, the Portfolio has appealed the assessment and has been advised by Indian legal counsel that it has a strong case for appeal with ultimate success. The appeal process may be lengthy and will involve expense to the Portfolio. The Indian tax authority has required the Portfolio to pay the assessed amount pending the appeal. The Portfolio has paid such amount to the tax authority. Such amount is reflected as a tax claim receivable on the Statement of Assets and Liabilities. 7 LINE OF CREDIT The Portfolio participates with other portfolios and funds managed by EVM and its affiliates in a committed $150 million unsecured line of credit agreement with a group of banks. The Portfolio may temporarily borrow from the line of credit to satisfy redemption requests or settle investment transactions. 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 December 31, 2004. 22 <Page> SOUTH ASIA PORTFOLIO as of December 31, 2004 REPORT OF INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM TO THE TRUSTEES AND INVESTORS OF SOUTH ASIA PORTFOLIO We have audited the accompanying statement of assets and liabilities, including the portfolio of investments, of South Asia Portfolio (the Portfolio) as of December 31, 2004, and the related statement of operations for the year then ended, the statements of changes in net assets for each of the two years in the period then ended, and the supplementary data for each of the five years in the period then ended. 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 the standards of the Public Company Accounting Oversight Board (United States). Those standards 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 consideration of internal control over financial reporting as a basis for designing audit procedures that are appropriate in the circumstances, but not for the purpose of expressing an opinion on the effectiveness of the Fund's internal control over financial reporting. Accordingly, we express no such opinion. An audit also 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, as well as evaluating the overall financial statement presentation.

(3) All other fees consist of the aggregate fees billed for products and services provided by the registrant's principal accountant other than audit, audit-related, and tax services. (e)(1) The registrant's audit committee has adopted policies and procedures relating to the pre-approval of services provided by the registrant's principal accountant (the "Pre-Approval Policies").

As a general matter, the Pre-Approval Policies (i) specify certain types of audit, audit-related, tax, and other services <Page> determined to be pre-approved by the audit committee; and (ii) delineate specific procedures governing the mechanics of the pre-approval process, including the approval and monitoring of audit and non-audit service fees. Unless a service is specifically pre-approved under the Pre-Approval Policies, it must be separately pre-approved by the audit committee. The Pre-Approval Policies and the types of audit and non-audit services pre-approved therein must be reviewed and ratified by the registrant's audit committee at least annually. The registrant's audit committee maintains full responsibility for the appointment, compensation, and oversight of the work of the registrant's principal accountant.

(h) The registrant's audit committee has considered whether the provision by the registrant's principal accountant of non-audit services to the registrant's investment adviser and any entity controlling, controlled by, or under common control with the adviser that provides ongoing services to the registrant that were not pre-approved pursuant to Rule 2-01(c)(7)(ii) of Regulation S-X is compatible with maintaining the principal accountant's independence.
