⁽¹⁾ The investment adviser and administrator and the sub-adviser have agreed to reimburse the Fund’s expenses to the extent that Total Annual Fund Operating Expenses exceed 1.15% for Class A shares, 1.90% for Class C shares and 0.90% for Class I shares. This expense reimbursement will continue through November 30, 2018. Any amendment to or termination of this reimbursement would require approval of the Board of Trustees. The expense reimbursement relates to ordinary operating expenses and acquired fund fees and expenses and does not include expenses such as: brokerage commissions, interest expense, taxes or litigation expenses. Amounts reimbursed may be recouped by the investment adviser and administrator and the sub-adviser during the same fiscal year to the extent actual expenses are less than the contractual expense cap during such year.

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:

	Expenses with Redemption				Expenses without Redemption
	1 Year	3 Years	5 Years	10 Years	1 Year	3 Years	5 Years	10 Years
Class A shares	$685	$969	$1,274	$2,138	$685	$969	$1,274	$2,138
Class C shares	$293	$649	$1,131	$2,463	$193	$649	$1,131	$2,463
Class I shares	$92	$341	$609	$1,375	$92	$341	$609	$1,375

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 109% of the average value of its portfolio.

Principal Investment Strategies

Under normal market conditions, the Fund invests at least 80% of its net assets (plus any borrowings for investment purposes) in equity securities of issuers located throughout the developed world, including the United States (the “80% Policy”). A company will be considered to be located in the developed world if it is domiciled in and tied economically to one or more developed countries as defined by the MSCI World Index. The MSCI World Index is an unmanaged index of approximately 1,600 companies located in 23 countries. Under normal market conditions, the Fund will invest (i) at least 30% of its net assets in companies located outside the United States, including in emerging market countries and (ii) in issuers located in at least five different countries (including the United States). A company will be considered to be located outside the United States if it is domiciled in and tied economically to one or more non-U.S. countries and may include stocks of companies that trade in the form of depositary receipts.

The Fund may invest in securities issued by companies with a broad range of market capitalizations, including smaller companies. The Fund may invest in exchange-traded funds (“ETFs”), a type of pooled investment vehicle, in order to equitize cash positions or seek exposure to certain markets or market sectors. The Fund will actively manage its exposure to foreign currencies and may seek to enhance return by increasing or decreasing its exposure to foreign currencies. The Fund expects to increase or decrease its foreign currency exposure primarily by entering into forward foreign currency exchange contracts. The Fund may also invest in futures contracts to enable changes in macroeconomic views to be efficiently and cost-effectively implemented, as well as to manage cash flows. Both forward foreign currency exchange contracts and futures contracts are types of derivative instruments. The Fund may also use derivatives consistent with its 80% Policy.

The Fund is managed using a predominately top-down investment style that incorporates proprietary fundamental research and quantitative models. The regional, country, currency, sector, and industry allocations of the portfolio are based primarily on the sub-adviser’s analysis of the macroeconomic environment, valuations of markets and the sentiment of investors (which often results in a contrarian view and value bias). Individual stock selection is based on fundamental research, optimization and quantitative screening to achieve desired market exposures and to emphasize stocks identified as having higher return potential. At the top-down level, sell decisions will be based on a significant deterioration in the macroeconomic environment, valuation and/or sentiment. At the individual security level, sell decisions are based on a change in views at the top-down level or on a significant change in fundamentals or relative valuation of the security. The portfolio managers seek to manage investment risk by using quantitative tools to assist in portfolio construction and monitoring and maintaining desired market exposures across the Fund’s holdings.

Principal Risks

Equity Investing Risk. Fund performance is sensitive to stock market volatility. Stock prices may decline in response to adverse changes in the economy or the economic outlook; deterioration in investor sentiment; interest rate, currency, and commodity price fluctuations; adverse geopolitical, social or environmental developments; issuer- and sector-specific considerations; and other factors. 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. Although stock prices 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 shares may be adversely affected by changes in currency exchange rates and political, economic and market developments abroad, including the imposition of economic and other sanctions by the United States or another country. Investment markets in emerging market countries are typically smaller, less liquid and more

Eaton Vance Hexavest Global Equity Fund 2 Summary Prospectus dated December 1, 2017

volatile than developed markets, and emerging market securities often involve higher risk than developed market securities. Trading in foreign markets often involves higher expense than trading in the United States. 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 instruments.

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, which represents a non-cash exposure to the underlying asset, index, rate or instrument. Leverage can increase both the risk and return potential of the Fund. 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.   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. Changes in the value of a derivative may not correlate perfectly with the underlying asset, rate or index. Derivative instruments traded in over-the-counter markets 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, particularly when there is no stated limit on the Fund’s use of derivatives.

Currency Risk. In general, fluctuations in foreign currency values will result in fluctuations in the U.S. dollar value of Fund securities denominated in that foreign currency. If the U.S. dollar rises in value relative to a foreign currency, a security denominated in that foreign currency will be worth less in U.S. dollars. If the U.S. dollar decreases in value relative to a foreign currency, a security denominated in that foreign currency will be worth more in U.S. dollars. The value of foreign currencies as measured in U.S. dollars may be unpredictably affected by changes in foreign currency rates and exchange control regulations, application of foreign tax laws (including withholding tax), governmental administration of economic or monetary policies (in the U.S. or abroad), intervention (or the failure to intervene) by U.S. or foreign governments or central banks, and relations between nations.  A devaluation of a currency by a country’s government or banking authority will have a significant impact on the value of any investments denominated in that currency. Currency markets generally are not as regulated as securities markets and currency transactions are subject to settlement, custodial and other operational risks. Exposure to foreign currencies through derivative instruments will be subject to derivative risks described herein.

Smaller Company Equity Risk. The stocks of smaller, less seasoned companies are generally subject to greater price fluctuations, limited liquidity, higher transaction costs and higher investment risk than the stocks of larger, more established companies. Smaller, less seasoned 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.

ETF Risk. ETFs are subject to the risks of investing in the underlying securities. ETF shares may trade at a premium or discount to net asset value and are subject to secondary market trading risks. In addition, the Fund will bear a pro rata portion of the operating expenses of an ETF in which it invests.

Risks Associated with Active and Quantitative Management. The success of the Fund’s investment program depends on portfolio management’s successful application of analytical skills and investment judgment. Active management involves subjective decisions. The portfolio managers also use quantitative investment techniques and analyses in making investment decisions for the Fund. There can be no assurance that these techniques will achieve the desired results.

General Fund Investing Risks. The Fund is not a complete investment program and there is no guarantee that the Fund will achieve its investment objective. It is possible to lose money by investing in the Fund. The Fund is designed to be a long-term investment vehicle and is not suited for short-term trading. Investors in the Fund should have a long-term investment perspective and be able to tolerate potentially sharp declines in value. Purchase and redemption activities by Fund shareholders may impact the management of the Fund and its ability to achieve its investment objective. In addition, the redemption by one or more large shareholders or groups of shareholders of their holdings in the Fund could have an adverse impact on the remaining shareholders in the Fund. 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.

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 not necessarily an indication of how the Fund will perform in the future. 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 period from December 31, 2012 to December 31, 2016, the highest quarterly total return for Class A was 8.48% for the quarter ended March 31, 2013 and the lowest quarterly return was -5.53% for the quarter ended September 30, 2015. The year-to-date total return through the end of the most recent calendar quarter (December 31, 2016 to September 30, 2017) was 9.87%.

Average Annual Total Return as of December 31, 2016	One Year	Life of Fund
Class A Return Before Taxes	5.34%	7.34%
Class A Return After Taxes on Distributions	4.38%	6.04%
Class A Return After Taxes on Distributions and the Sale of Class A Shares	3.69%	5.48%
Class C Return Before Taxes	10.70%	8.80%
Class I Return Before Taxes	12.07%	9.08%
MSCI World Index (reflects net dividends, which reflects the deduction of withholding taxes)	7.51%	9.57%

These returns reflect the maximum sales charge for Class A (5.75%). Class A and Class I commenced operations on August 29, 2012. The Class C performance shown above for the period prior to December 1, 2016 (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 such differences, returns would be different. (Source for the MSCI World Index: MSCI.) MSCI data may not be reproduced or used for any other purpose. MSCI provides no warranties, has not prepared or approved this report, and has no liability hereunder. 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 A shares. Return After Taxes on Distributions for a period may be the same as Return Before Taxes for that 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.
