Investment Objective

The Fund’s investment objective is total return.

Fees and Expenses of the Fund

This table describes the fees and expenses that you may pay if you buy and hold shares of the Fund.  You may qualify for a reduced sales charge if you invest, or agree to invest over a 13-month period, at least $50,000 in Eaton Vance Funds.  More information about these and other discounts is available from your financial intermediary and in Sales Charges beginning on page 22 of the Fund's Prospectus and page 19 of the Fund’s Statement of Additional Information.  

Shareholder Fees (fees paid directly from your investment)	Class A	Class C	Class I
Maximum Sales Charge (Load) Imposed on Purchases (as a percentage of offering price)	5.75%	None	None
Maximum Deferred Sales Charge (Load) (as a percentage of the lower of net asset value at time of purchase or redemption)	None	1.00%	None

Annual Fund Operating Expenses (expenses you pay each year as a percentage of the value of your investment)	Class A	Class C	Class I
Management Fees	0.90%	0.90%	0.90%
Distribution and Service (12b-1) Fees	0.25%	1.00%	n/a
Other Expenses	0.18%	0.18%	0.19%
Acquired Fund Fees and Expenses	0.07%	0.07%	0.07%
Total Annual Fund Operating Expenses	1.40%	2.15%	1.16%

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	$709	$993	$1,297	$2,158	$709	$993	$1,297	$2,158
Class C shares	$318	$673	$1,154	$2,483	$218	$673	$1,154	$2,483
Class I shares	$118	$368	$638	$1,409	$118	$368	$638	$1,409

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 42% of the average value of its portfolio.

Principal Investment Strategies

In seeking its investment objective, the Fund has flexibility to allocate its assets in markets around the world and among various asset classes, including equity, fixed-income, commodity, currency and cash investments.  

The Fund is managed in a macro-driven, top-down style that emphasizes and de-emphasizes various global market segments and asset classes at different times.  Market segments chosen for emphasis and/or de-emphasis may vary from general market consensus views and the Fund may at times seek to identify areas where there is in the sub-adviser’s opinion scarcity of capital and/or potentially overlooked investment opportunities.  Exposures will vary among asset classes based on the sub-adviser’s assessment of a range of proprietary and non-proprietary quantitative indicators and the firm’s macro-economic analysis and judgment.  It is expected that the macro-economic analysis will evolve over time and may include consideration of the following:  historical risk and return characteristics; global market valuations; global yield curves; asset class, regional, and country correlations; profit cycle analyses and style and sector rotation; expected beta; estimate revisions and earnings surprises; investor sentiment and other factors. Individual equity security selection is based on quantitative screening and optimization to achieve desired market exposures while seeking to manage security-specific and other observable market risks.  The portfolio is monitored on an ongoing basis and rebalanced as necessary to seek to ensure that desired market exposures and risk parameters are maintained.  Securities may be sold if they exhibit performance that might counteract the desired exposures or to implement a revised allocation based on a modified top-down view.

Under normal circumstances, the Fund currently expects to invest 0-75% of its net assets in equity securities, 25-90% in fixed-income securities, 0-25% in commodities (primarily through the use of exchange-traded funds (“ETFs”) that invest in commodities or commodities-related investments) and/or currencies, and 0-25% in cash and cash equivalents. The Fund may also invest in derivatives (as described below) to obtain such exposures.  To the extent the Fund holds cash as collateral for derivatives, or enters into forward foreign currency exchange contracts to hedge current portfolio holdings, the ranges described above may be exceeded. The expected long-term (over a true secular cycle of at least 10 years) target allocation of the Fund is 60% in fixed income securities and 40% in equity securities.  There is no requirement to manage the Fund within this target allocation. The Fund’s actual asset allocation may be materially different depending on market conditions and the Fund’s asset allocation over shorter or longer market cycles may differ materially from the target.

The Fund may invest without limit in both developed and emerging markets including frontier markets. Such investments may include securities denominated in foreign currencies and securities trading in the form of depositary receipts. The Fund may invest in fixed-income securities of any credit quality including, but not limited to, corporate bonds, securities issued or guaranteed by the U.S. government or its agencies or instrumentalities, obligations of other sovereign nations, municipal obligations, mortgage-backed securities and inflation-linked debt securities.  The Fund may invest in stocks of companies of any capitalization, publicly traded real estate investment trusts and exchange-traded notes (“ETNs”). The Fund may invest in certain ETFs beyond the limits under the Investment Company Act of 1940 (the “1940 Act”), subject to certain terms and conditions and may invest in other pooled investment vehicles (including affiliated and unaffiliated mutual funds to the extent permitted by the 1940 Act).  Investment in cash or cash equivalents may include U.S and foreign bank certificates of deposit, fixed time deposits, repurchase agreements, bankers’ acceptances and other short-term instruments with a remaining maturity of 397 days or less.  The Fund currently expects to gain exposures to certain types of investments principally through ETFs.  The Fund may also lend its securities.

The Fund may engage in derivative transactions to seek return, to hedge against fluctuations in securities prices, interest rates or currency exchange rates, to change the effective duration of the fixed-income securities in its portfolio, to manage certain investment risks and/or as a substitute for the purchase or sale of securities, currencies or commodities.  The Fund expects to use derivatives principally when seeking to gain exposure to equity or fixed-income securities using futures contracts on securities indices and/or when seeking to gain or reduce exposure to certain currencies by buying or selling forward foreign currency exchange contracts, but may also purchase or sell forwards or other types of futures contracts; options on futures contracts; exchange traded and over-the-counter options; equity collars, equity-linked securities and equity swap agreements; interest rate, total return, inflation and credit default swaps; forward rate agreements; and credit linked notes and other similarly structured products. The Fund may also engage in covered short sales (on individual securities held or on an index or basket of securities whose constituents are held in whole or in part or for which liquid assets have been segregated) and forward commitments.  There is no stated limit on the Fund’s use of derivatives.

Principal Risks

Equity Investing Risk. The Fund’s shares may be 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 value of equity investments and related instruments 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,

Eaton Vance Richard Bernstein All Asset Strategy Fund

2

Summary Prospectus dated January 1, 2015 as revised April 17, 2015

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.

Debt Market Risk.  Economic and other events (whether real or perceived) can reduce the demand for investments held by the Fund, which may reduce their market prices and cause the value of Fund shares to fall. The frequency and magnitude of such changes cannot be predicted.  Certain securities and other investments held by the Fund can experience downturns in trading activity and, at such times, the supply of such instruments in the market may exceed the demand.  At other times, the demand for such instruments may exceed the supply in the market.  An imbalance in supply and demand in the market may result in valuation uncertainties and greater volatility, less liquidity, wider trading spreads and a lack of price transparency in the market.  No active trading market may exist for certain investments, which may impair the ability of the Fund to sell or to realize the full value of such investments in the event of the need to liquidate such assets. Adverse market conditions may impair the liquidity of some actively traded investments.  Fixed income markets have recently experienced a period of relatively high volatility. If the Federal Reserve continues to taper or reverses its quantitative easing stimulus program and/or increases interest rates, fixed income markets could experience continuing high volatility, which could negatively impact the Fund’s performance.

Foreign and Emerging Market Investment Risk. Because the Fund can invest 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, including the imposition of economic and other sanctions by the United States or another country.  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 foregoing risks may be greater in frontier markets. 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.

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. 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, and the Fund could lose more than the principal amount invested.  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.

ETF Risk.  Investing in an ETF exposes the Fund to all of the risks of that ETF’s investments and subjects it to a pro rata portion of the ETF’s fees and expenses. As a result, the cost of investing in ETF shares may exceed the costs of investing directly in its underlying investments. ETF shares trade on an exchange at a market price, which may vary from the ETF’s net asset value.  The Fund may purchase ETFs at prices that exceed the net asset value of their underlying investments and may sell ETF investments at prices below such net asset value. Because the market price of ETF shares depends on the demand in the market for them, the market price of an ETF may be more volatile than the value of the underlying portfolio of securities the ETF is designed to track, and the Fund may not be able to liquidate ETF holdings at the time and price desired, which may impact Fund performance.

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.

Credit Risk.Investments in debt obligations are subject to the risk of non-payment of scheduled principal and interest.  Changes in economic conditions or other circumstances may reduce the capacity of the party obligated to make principal and interest payments on such instruments and may lead to defaults. Such non-payments and defaults may reduce the value of Fund shares and income distributions. The value of a debt obligation also may decline because of concerns about the issuer’s ability to make principal and interest payments. In addition, the credit ratings of fixed income securities may be lowered if the financial condition

Eaton Vance Richard Bernstein All Asset Strategy Fund

Summary Prospectus dated January 1, 2015 as revised April 17, 2015

of the party obligated to make payments with respect to such instruments changes.  Credit ratings assigned by rating agencies are based on a number of factors and do not necessarily reflect the issuer’s current financial condition or the volatility or liquidity of the security.  In the event of bankruptcy of the issuer of fixed income securities, the Fund could experience delays or limitations with respect to its ability to realize the benefits of any collateral securing the instrument. In order to enforce its rights in the event of a default, bankruptcy or similar situation, the Fund may be required to retain legal or similar counsel.  This may increase the Fund’s operating expenses and adversely affect net asset value.

Interest Rate Risk.In general, the value of income securities will fluctuate based on changes in interest rates.  The value of these securities is likely to increase when interest rates fall and decline when interest rates rise.  Generally, securities with longer durations are more sensitive to changes in interest rates than shorter duration securities.  In a rising interest rate environment, the duration of income securities that have the ability to be prepaid or called by the issuer may be extended.  In a declining interest rate environment, the proceeds from prepaid or maturing instruments may have to be reinvested at a lower interest rate.

Risk of U.S. Government-Sponsored Agencies.  Although certain U.S. Government-sponsored agencies (such as the Federal Home Loan Mortgage Corporation and the Federal National Mortgage Association) may be chartered or sponsored by acts of Congress, their securities are neither issued nor guaranteed by the U.S. Treasury.

Risk of Lower Rated Investments. Investments rated below investment grade and comparable unrated securities (“junk bonds”) have speculative characteristics because of the credit risk associated with their issuers.  Changes in economic conditions or other circumstances typically have a greater effect on the ability of issuers of lower rated investments to make principal and interest payments than they do on issuers of higher rated investments.  An economic downturn generally leads to a higher non-payment rate, and a lower rated investment may lose significant value before a default occurs.  Lower rated investments typically are subject to greater price volatility and illiquidity than higher rated investments.

Municipal Bond Risk. The amount of public information available about municipal bonds is generally less than for corporate equities or bonds, meaning that the investment performance of municipal bond investments may be more dependent on the analytical abilities of the investment adviser than stock or corporate bond investments. The secondary market for municipal bonds also tends to be less well-developed and less liquid than many other securities markets, which may limit an owner’s ability to sell its municipal bonds at attractive prices.  The spread between the price at which an obligation can be purchased and the price at which it can be sold may widen during periods of market distress.  Less liquid obligations can become more difficult to value and be subject to erratic price movements.  The increased presence of non-traditional participants or the absence of traditional participants in the municipal markets may lead to greater volatility in the markets.

Real Estate Investment Trust Risk.  Real estate investment trusts (“REITs”) are subject to special risks associated with real estate.  Securities of companies in the real estate industry are sensitive to factors such as changes in real estate values, property taxes, interest rates, cash flow of underlying real estate assets, occupancy rates, government regulations affecting zoning, land use, and rents, and the management skill and creditworthiness of the issuer.  Companies in the real estate industry may also be subject to liabilities under environmental and hazardous waste laws, among others.  Changes in underlying real estate values may have an exaggerated effect to the extent that REITs concentrate investments in particular geographic regions or property types.

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.

Risks of Commodity-Related Investments.  The value of commodity investments will generally be affected by overall market movements and factors specific to a particular industry or commodity, which may include weather, embargoes, tariffs, and health, political, international and regulatory developments. Economic and other events (whether real or perceived) can reduce the demand for commodities, which may reduce market prices and cause the value of the Fund’s commodity investments to fall. The frequency and magnitude of such changes cannot be predicted. Exposure to commodities and commodity markets may subject the Fund to greater volatility than investments in traditional securities. No active trading market may exist for certain commodity investments, which may impair the ability of the Fund to sell or to realize the full value of such investments in the event of the need to liquidate such investments and/or shares of an ETF that invests in such investments. In addition, adverse

Eaton Vance Richard Bernstein All Asset Strategy Fund

4

Summary Prospectus dated January 1, 2015 as revised April 17, 2015

market conditions may impair the liquidity of actively traded commodity investments.  Certain types of commodity instruments (such as total return swaps and commodity-linked notes) are subject to the risk that the counterparty to the instrument will not perform or will be unable to perform in accordance with the terms of the instrument.

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 sub-adviser is unable to reinvest cash collateral at rates that exceed the costs involved.

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

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 two broad-based securities market indices and with a blended 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 return 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 for certain periods.  Absent these reductions, performance for certain periods would have been lower.  Updated Fund performance information can be obtained by visiting www.eatonvance.com.

During the period from December 31, 2011 through December 31, 2013, the highest quarterly total return for Class A was 5.96% for the quarter ended March 31, 2013, and the lowest quarterly return was -0.94% for the quarter ended June 30, 2013.  The year-to-date total return through the end of the most recent calendar quarter (December 31, 2013 to September 30, 2014) was 2.33%.   

Average Annual Total Return as of December 31, 2013	One Year	Life of Fund
Class A Return Before Taxes	6.94%	8.66%
Class A Return After Taxes on Distributions	6.67%	8.41%
Class A Return After Taxes on Distributions and the Sale of Class A Shares	4.15%	6.73%
Class C Return Before Taxes	11.57%	10.69%

Summary Prospectus dated January 1, 2015 as revised April 17, 2015

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.
