Example.

This Example is intended to help you compare the cost of investing in the Fund with the cost of investing in other mutual funds. The Example assumes that you invest $10,000 in the Fund for the time periods indicated and then redeem all of your shares at the end of those periods. The Example also assumes that your investment has a 5% return each year and that the operating expenses remain the same. Although your actual costs may be higher or lower, based on these assumptions your costs would be:

Portfolio Turnover

The Fund pays transaction costs, such as commissions, when it buys and sells securities (or “turns over” the portfolio). A higher portfolio turnover rate may indicate higher transaction costs and may result in higher taxes when Fund shares are held in a taxable account. These costs, which are not reflected in Annual Fund Operating Expenses or in the Example, affect the Fund’s performance. During the most recent fiscal year, the Fund's portfolio turnover rate was 49 % of the average value of its portfolio.

Principal Investment Strategies

Under normal market conditions, the Fund invests at least 80% of its net assets in equity securities of companies in India and surrounding countries of the Indian subcontinent (“Greater India investments”) (the “80% Policy”). A company will be considered to be in India or another country if it is domiciled in or derives more than 50% of its revenue or profits from that country. Greater India investments are typically listed on stock exchanges in countries of the Indian subcontinent, but also include securities traded in markets outside these countries, including securities trading in the form of depositary receipts. The Fund normally invests at least 50% of its total assets in equity securities of Indian companies, and no more than 5% of its total assets in companies located in countries other than India, Pakistan or Sri Lanka.

The Fund invests in companies with a broad range of market capitalizations, including smaller companies. The Fund may make direct investments in companies in private placement transactions. More than 25% of the Fund’s total assets may be denominated in any single currency. The portfolio manager may (but is not obligated to) use investments such as forward contracts and options to attempt to mitigate the adverse effects of foreign currency fluctuations. The Fund may utilize index or stock futures for the limited purpose of managing cash flows. The Fund limits investment in such index or stock futures to not more than 20% of its total assets. The Fund may also lend its securities.

In selecting securities for the Fund, the investment adviser considers companies that it believes have all or most of the following characteristics: sound and well-established management; producers of goods or services for which a clear, continuing and long-term demand can be identified within the context of national, regional and global development; a history of earnings growth; financial strength; a consistent or progressive dividend policy; and undervalued securities. Stocks will generally be sold when they have achieved their perceived value or when a country’s stock market is expected to be depressed for an extended period.

The Fund primarily invests its assets in Greater India Portfolio (the “Portfolio”), a separate registered investment company with the same objective and policies as the Fund.

Principal Risks

Equity Investing Risk. The Fund’s shares are sensitive to stock market volatility and the stocks in which the Fund invests may be more volatile than the stock market as a whole. The prices of stocks may decline in response to conditions affecting the general economy; overall market changes; local, regional or global political, social or economic instability; and currency, interest rate and commodity price fluctuations, as well as issuer or sector specific events. Market conditions may affect certain types of stocks to a greater extent than other types of stocks. If the stock market declines, the value of Fund shares will also likely decline and , although stock values can rebound, there is no assurance that values will return to previous levels.

Foreign and Emerging Market Investment Risk . Because the Fund invests a significant portion of its assets in foreign instruments, the value of Fund shares can be adversely affected by changes in currency exchange rates and political , economic and market developments abroad. In emerging or less developed countries, these risks can be more significant. Investment markets in emerging market countries are typically substantially smaller, less liquid and more volatile than the major markets in developed countries . As a result, Fund share values may be more volatile than if the Fund invested only in developed markets . Emerging market countries may have relatively unstable governments and economies. Emerging market investments often are subject to speculative trading, which typically contributes to volatility. Trading in foreign and emerging markets typically involves higher expense than trading in the United States. The Fund may have difficulties enforcing its legal or contractual rights in a foreign country. The value of investments denominated in foreign currencies can be adversely affected by changes in foreign currency exchange rates. Depositary receipts are subject to many of the risks associated with investing directly in foreign securities , including political , economic and market risks.

Risks of Investing in India. Countries in the India region are typically considered emerging market countries. The securities markets in the India region are substantially smaller, less liquid and more volatile than the major securities markets in the United States, and are undergoing a period of growth and change, which may result in trading or price volatility and difficulties in the settlement and recording of transactions, and in interpreting and applying relevant laws and regulations. The securities markets in these countries are comparatively underdeveloped and may be concentrated in certain sectors. In addition, governmental actions can have a significant effect on the economic conditions in the India region, which could adversely affect the value and liquidity of investments.

Small Company Equity Risk . The stocks of small and emerging companies are generally subject to greater price fluctuations, limited liquidity, higher transaction costs and higher investment risk. Small and emerging companies may have limited product lines, markets or financial resources, may be dependent on a limited management group, and may lack substantial capital reserves or an established performance record. There may be generally less publicly available information about such companies than for larger, more established companies. Stocks of these companies frequently have lower trading volumes making them more volatile and potentially more difficult to value.

Geographic Concentration Risk. Because the Fund will concentrate its investments in equity securities of companies located in the region defined in Principal Investment Strategies above, the value of Fund shares may be affected by events that adversely affect that region and may fluctuate more than that of a less concentrated fund.

Derivatives Risk. The use of derivatives can lead to losses because of adverse movements in the price or value of the asset, index, rate or instrument underlying a derivative, due to failure of a counterparty or due to tax or regulatory constraints. Derivatives may create economic leverage in the Fund, which magnifies the Fund’s exposure to the underlying investment. Derivatives risk may be more significant when derivatives are used to enhance return or as a substitute for a cash investment position, rather than solely to hedge the risk of a position held by the Fund. When derivatives are used to gain or limit exposure to a particular market or market segment, their performance may not correlate as expected to the performance of such market thereby causing the Fund to fail to achieve its original purpose for using such derivatives. A decision as to whether, when and how to use derivatives involves the exercise of specialized skill and judgment, and a transaction may be unsuccessful in whole or in part because of market behavior or unexpected events. Derivative instruments may be difficult to value, may be illiquid, and may be subject to wide swings in valuation caused by changes in the value of the underlying instrument. If a derivative’s counterparty is unable to honor its commitments, the value of Fund shares may decline and the Fund could experience delays in the return of collateral or other assets held by the counterparty. The loss on derivative transactions may substantially exceed the initial investment.

Securities Lending Risk. Securities lending involves possible delay in recovery of the securities or possible loss of rights in the collateral should the borrower fail financially. As a result, the value of Fund shares may fall and there may be a delay in recovering the loaned securities. The value of Fund shares could also fall if a loan is called and the Fund is required to liquidate reinvested collateral at a loss or if the investment adviser is unable to reinvest cash collateral at rates that exceed the costs involved.

Risks Associated with Active Management. The Fund is an actively managed portfolio and its success depends upon the investment skills and analytical abilities of the investment adviser to develop and effectively implement strategies to achieve the Fund’s investment objective. Subjective decisions made by the investment adviser may cause the Fund to incur losses or to miss profit opportunities on which it may otherwise have capitalized.

General Fund Investing Risks. The Fund is not a complete investment program and you may lose money by investing in the Fund. All investments carry a certain amount of risk and there is no guarantee that the Fund will be able to achieve its investment objective. Annual Fund Operating Expenses expressed as a percentage of the Fund’s average daily net assets may change as Fund assets increase and decrease, and Annual Fund Operating Expenses may differ in the future. Purchase and redemption activities by Fund shareholders may impact the management of the Fund and its ability to achieve its investment objective. Investors in the Fund should have a long-term investment perspective and be able to tolerate potentially sharp declines in value. An investment in the Fund is not a deposit in a bank and is not insured or guaranteed by the Federal Deposit Insurance Corporation or any other government agency, entity or person. Mutual funds, investment advisers, other market participants and many securities markets are subject to rules and regulations and the jurisdiction of one or more regulators. Changes to applicable rules and regulations could have an adverse affect on securities markets and market participants, as well as on the Fund’s ability to execute its investment strategy.

Performance

The following bar chart and table provide some indication of the risks of investing in the Fund by showing changes in the Fund’s performance from year to year and how the Fund’s average annual returns over time compare with those of a broad-based securities market index. The returns in the bar chart are for Class A shares and do not reflect a sales charge. If the sales charge was reflected, the returns would be lower. Past performance (both before and after taxes) is no guarantee of future results. The Fund’s performance reflects the effects of expense reductions. Absent these reductions, performance would have been lower. Updated Fund performance information can be obtained by visiting www.eatonvance.com.

During the ten years ended December 31, 2011 , the highest quarterly total return for Class A was 61.09 % for the quarter ended June 30, 2009, and the lowest quarterly return was - 28. 06 % for the quarter ended December 31, 2008.

Returns prior to September 30, 2002 are calculated as a price return by Bloomberg. These returns reflect the maximum sales charge for Class A (5.75%) and any applicable contingent deferred sales charge (“CDSC”) for Class B and Class C. The Class C performance shown above for the period prior to July 7, 2006 (commencement of operations) is the performance of Class B shares, adjusted for the sales charge that applies to Class C shares (but not adjusted for any other differences in the expenses of the two classes) and the Class I performance shown above for the period prior to October 1, 2009 (commencement of operations) is the performance of Class A shares at net asset value without adjustment for any differences in the expenses of the two classes. If adjusted for other expenses, returns would be different. Investors cannot invest directly in an Index.

After-tax returns are calculated using the highest historical individual federal income tax rates and do not reflect the impact of state and local taxes. Actual after-tax returns depend on a shareholder’s tax situation and the actual characterization of distributions, and may differ from those shown. After-tax returns are not relevant to shareholders who hold shares in tax-deferred accounts or to shares held by non-taxable entities. After-tax returns for other Classes of shares will vary from the after-tax returns presented for Class B shares. Return After Taxes on Distributions may be the same as Return Before Taxes for a period because no taxable distributions were made during that period. Also, Return After Taxes on Distributions and the Sale of Fund Shares for a period may be greater than or equal to Return After Taxes on Distributions for the same period because of losses realized on the sale of Fund shares.

[1] Expenses in the table above and the Example below reflect the expenses of the Fund and the Portfolio.

[2] The investment adviser and sub-adviser have agreed to reimburse the Fund's expenses to the extent that Total Annual Fund Operating Expenses exceed 1.88% for Class A shares, 2.58% for Class B and Class C shares and 1.58% for Class I shares. This expense reimbursement will continue through April 28, 2013. Any amendment to or a termination of this reimbursement would require written approval of the Board of Trustees. The expense reimbursement relates to ordinary operating expenses only and does not include expenses such as: brokerage commissions, acquired fund fees and expenses, interest expense, taxes or litigation expenses. Amounts reimbursed may be recouped by the investment adviser and sub-adviser during the Fund's current fiscal year to the extent actual expenses are less than the contractual expense cap during such year .
