The Fund and the Portfolios in which
it invests (see below) pay transaction costs, such as commissions, when they buy and sell securities (or “turn 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 4% of the average
value of its portfolio. The Fund's portfolio turnover rate is based on the Fund's contributions to and withdrawals from the Portfolios
and excludes the investment activity of the Portfolios.

| Investment Strategy, Narrative |
rr_StrategyNarrativeTextBlock |
The Fund seeks to achieve its investment
objective by allocating assets between common stocks and fixed-income securities through its investment in two other registered
investment companies managed by Eaton Vance Management or its affiliates (the “Portfolios”). Under normal market conditions,
the Fund invests between 50% and 75% of its net assets in equity securities by investing in Stock Portfolio and between 25% and
50% of its net assets in fixed-income securities by investing in Core Bond Portfolio. Set forth below is an overview of the Fund’s
investment practices, followed by a description of the characteristics and risks associated with the principal investments and
strategies of the Fund as a result of its investment in the Portfolios.
The Fund’s equity securities are
primarily common stocks issued by companies with a broad range of market capitalizations, including smaller companies. The
Fund’s fixed-income securities may include corporate bonds, U.S. Government securities, money market instruments, mortgage-backed
securities (including collateralized mortgage obligations), commercial mortgage-backed securities, asset-backed securities (including
collateralized debt obligations and collateralized loan obligations), convertible debt securities and other hybrid securities (which
have characteristics of equity and debt securities), inflation-linked debt securities and municipal securities. The Fund
may also invest in floating rate instruments, including loans. A significant portion of the Fund’s fixed-income investments
may be in securities issued by various U.S. Government-sponsored entities, such as the Federal Home Loan Mortgage Corporation,
the Federal National Mortgage Association and Federal Home Loan Banks. Instruments may be of any credit quality (including
in default), but investment in instruments rated below investment grade (including securities, loans and credit derivatives where
the credit rating of the reference instrument is below investment grade) is limited to not more than 15% of total fixed income
assets. Instruments rated below investment grade are rated below BBB by S&P Global Ratings (“S&P”) or
by Fitch Ratings (“Fitch”) or Baa by Moody's Investors Service, Inc. (“Moody's”) (bonds so rated
are also called “junk bonds”). For purposes of rating restrictions, if instruments are rated differently by two or
more rating agencies, the highest rating is used. The Fund may invest up to 25% of its total assets in foreign securities,
some of which may be issued by companies domiciled in emerging market countries. As an alternative to holding foreign securities
directly, the Fund may invest in U.S. dollar-denominated securities of foreign companies that trade on U.S. exchanges or in the
over-the-counter market (including depositary receipts that evidence ownership in underlying foreign stocks and Eurodollar and
Yankee Dollar instruments). The Fund may invest in publicly traded real estate investment trusts (“REITs”) and may
invest in restricted securities. The portfolio managers may also use sector rotation strategies in their management of the Fund.
The Fund may engage in derivative transactions
to seek return, to hedge against fluctuations in securities prices, interest rates or currency exchange rates, or as a substitute
for the purchase or sale of securities or currencies. Permitted derivatives include: the purchase or sale of credit derivatives,
including credit default swaps, total return swaps and credit options; interest rate swaps, forward rate contracts; the purchase
or sale of forwards or futures contracts; options on futures contracts; exchange-traded and over-the-counter options; swaptions;
equity collars and equity swap agreements. There is no stated limit on the Fund’s use of derivatives other than as stated
above. 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).
To determine the exact percentage of
the Fund’s assets that will be invested from time to time in each Portfolio, the portfolio managers of the Portfolios meet
periodically and, taking market and other factors into consideration, agree upon an allocation.

|
|
| Risk, Heading |
rr_RiskHeading |
Principal Risks
|
|
| Risk, Narrative |
rr_RiskNarrativeTextBlock |
Market Risk. The value of
investments held by the Fund may increase or decrease in response to economic, political and financial events (whether real, expected
or perceived) in the U.S. and global markets. The frequency and magnitude of such changes in value cannot be predicted. Certain
securities and other investments held by the Fund may experience increased volatility, illiquidity, or other potentially adverse
effects in reaction to changing market conditions. Actions taken by the U.S. Federal Reserve or foreign central banks to stimulate
or stabilize economic growth, such as decreases or increases in short-term interest rates, could cause high volatility in markets.
No active trading market may exist for certain investments, which may impair the ability of the Fund to sell or to realize the
current valuation of such investments in the event of the need to liquidate such assets. Fixed-income markets may experience periods
of relatively high volatility in an environment where U.S. treasury yields are rising.
Equity Securities Risk. The
value of equity securities and related instruments 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; or other factors. Market conditions may affect certain types
of stocks to a greater extent than other types of stocks. If the stock market declines in value, the value of the Fund’s
equity securities will also likely decline. Although prices can rebound, there is no assurance that values will return to previous
levels.
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 maturities are more sensitive
to changes in interest rates than shorter maturity securities, causing them to be more volatile. Conversely, fixed income securities
with shorter maturities will be less volatile but generally provide lower returns than fixed income securities with longer maturities.
In a rising interest rate environment, the maturities 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.
Credit Risk. Investments
in fixed income and other debt obligations, including loans, (referred to below as “debt instruments”) 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 debt instruments also may
decline because of concerns about the issuer’s ability to make principal and interest payments. In addition, the credit ratings
of debt instruments may be lowered if the financial condition of the party obligated to make payments with respect to such instruments
deteriorates. In the event of bankruptcy of the issuer of a debt instrument, 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, which may increase
the Fund’s operating expenses and adversely affect net asset value.
U.S. Government Securities Risk. 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. U.S. Treasury securities generally have a lower return than other obligations because of their higher credit quality
and market liquidity.
Money Market Instrument Risk. Money
market instruments may be adversely affected by market and economic events, such as a sharp rise in prevailing short-term interest
rates; adverse developments in the banking industry, which issues or guarantees many money market instruments; adverse economic,
political or other developments affecting issuers of money market instruments; changes in the credit quality of issuers; and default
by a counterparty.
Mortgage-Backed Securities Risk. Mortgage-backed
securities represent interests in “pools” of commercial or residential mortgages. Movements in interest rates (both
increases and decreases) may quickly and significantly reduce the value of certain types of mortgage-backed securities. Although
certain mortgage-backed securities are guaranteed as to timely payment of interest and principal by a government entity, the market
price for such securities is not guaranteed and will fluctuate. The purchase of mortgage-backed securities issued by non-government
entities may entail greater risk than such securities issued or guaranteed by a government entity. Mortgage-backed securities issued
by non-government entities may also be subject to greater volatility than government issues and can also be subject to greater
credit risk and the risk of default on the underlying mortgages or other assets. Investments in mortgage-backed securities are
subject to both extension risk, where borrowers pay off their debt obligations more slowly in times of rising interest rates, and
prepayment risk, where borrowers pay off their debt obligations sooner than expected in times of declining interest rates.
Convertible and Other Hybrid Securities
Risk. Convertible and other hybrid securities generally possess characteristics common to both equity and debt securities.
In addition to risks associated with investing in income securities, such as interest rate and credit risks, convertible and other
hybrid securities may be subject to issuer-specific and market risks generally applicable to equity securities. Convertible securities
may also react to changes in the value of the common stock into which they convert, and are thus subject to equity investing and
market risks. A convertible security may be converted at an inopportune time, which may decrease the Fund’s return.
Lower Rated Investments Risk. Investments
rated below investment grade and comparable unrated investments (sometimes referred to as “junk”) 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.
Foreign Investment Risk. Foreign
investments can be adversely affected by political, economic and market developments abroad, including the imposition of economic
and other sanctions by the United States or another country. Foreign markets may be smaller, less liquid and more volatile than
the major markets in the United States, and as a result, Fund share values may be more volatile. Trading in foreign 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. Depositary receipts are subject to many of the risks associated with investing directly in foreign instruments.
Emerging Markets Investment Risk. Investment
markets in emerging market countries are typically smaller, less liquid and more volatile than developed markets, and emerging
market securities often involve greater risks than developed market securities.
Currency Risk. Exchange rates
for currencies fluctuate daily. The value of foreign investments may be affected favorably or unfavorably by changes in currency
exchange rates in relation to the U.S. dollar. Currency markets generally are not as regulated as securities markets and currency
transactions are subject to settlement, custodial and other operational risks.
Smaller Company 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. Such 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.
Real Estate Risk. Real estate
investments are subject to risks associated with owning real estate, including declines in real estate values, increases in property
taxes, fluctuations in interest rates, limited availability of mortgage financing, decreases in revenues from underlying real estate
assets, declines in occupancy rates, changes in government regulations affecting zoning, land use, and rents, environmental liabilities,
and risks related to 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. REITs must satisfy specific requirements for
favorable tax treatment and can involve unique risks in addition to the risks generally affecting the real estate industry. The
Fund is not eligible for a deduction from dividends received from REITs that is available to individuals who invest directly in
REITs. Changes in underlying real estate values may have an exaggerated effect to the extent that investments are concentrated
in particular geographic regions or property types.
Derivatives Risk. The Fund’s
exposure to derivatives involves risks different from, or possibly greater than, the risks associated with investing directly in
securities and other investments. 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 leverage in the Fund, 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. Use of 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 (including one used for
hedging) may not correlate perfectly with the underlying asset, rate, index or instrument. 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. A derivative investment also involves the risks relating to the asset, index, rate or instrument underlying
the investment.
Restricted and Illiquid Securities
Risk. Unless registered for sale to the public under applicable federal securities law, restricted securities can be sold
only in private transactions to qualified purchasers pursuant to an exemption from registration. The sale price realized from a
private transaction could be less than the Fund’s purchase price for the restricted security. It may be difficult to identify
a qualified purchaser for a restricted security held by the Fund and such security could be deemed illiquid. The Fund may not invest
more than 15% of its net assets in illiquid securities, which may be difficult to value properly and may involve greater risks
than liquid securities. Restricted securities may also be difficult to value.
When-Issued and Forward Commitment
Risk. Securities purchased on a when-issued or forward commitment basis are subject to the risk that when delivered they
will be worth less than the agreed upon payment price.
Inflation-Linked Investments Risk. Inflation-linked
investments are subject to the effects of changes in market interest rates caused by factors other than inflation (real interest
rates). In general, the price of an inflation-linked investment tends to decrease when real interest rates increase and increase
when real interest rates decrease. Interest payments on inflation-linked investments may vary widely and will fluctuate as the
principal and interest are adjusted for inflation. Any increase in the principal amount of an inflation-linked investment will
be considered taxable ordinary income, even though the Fund will not receive the principal until maturity. There can be no assurance
that the inflation index used will accurately measure the real rate of inflation in the prices of goods and services. The Fund’s
investments in inflation-linked investments may lose value in the event that the actual rate of inflation is different from the
rate of the inflation index.
Municipal Obligation Risk. The
amount of public information available about municipal obligations is generally less than for corporate equities or bonds, meaning
that the investment performance of municipal obligations may be more dependent on the analytical abilities of the investment adviser
than stock or corporate bond investments. The secondary market for municipal obligations also tends to be less well-developed and
less liquid than many other securities markets, which may limit the Fund’s ability to sell its municipal obligations at attractive
prices. The differences 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 nontraditional participants (such as proprietary trading desks of investment banks and hedge funds) or
the absence of traditional participants (such as individuals, insurance companies, banks and life insurance companies) in the municipal
markets may lead to greater volatility in the markets because non-traditional participants may trade more frequently or in greater
volume.
Additional Risks of Loans. Loans
are traded in a private, unregulated inter-dealer or inter-bank resale market and are generally subject to contractual restrictions
that must be satisfied before a loan can be bought or sold. These restrictions may impede the Fund’s ability to buy or sell
loans (thus affecting their liquidity) and may negatively impact the transaction price. See also “Market Risk” above.
It also may take longer than seven days for transactions in loans to settle. Due to the possibility of an extended loan settlement
process, the Fund may hold cash, sell investments or temporarily borrow from banks or other lenders to meet short-term liquidity
needs, such as to satisfy redemption requests from Fund shareholders. Loans may be structured such that they are not securities
under securities law, and in the event of fraud or misrepresentation by a borrower, lenders may not have the protection of the
anti-fraud provisions of the federal securities laws. Loans are also subject to risks associated with other types of income investments
as described herein.
Leverage Risk. Certain fund
transactions may give rise to leverage. Leverage can result from a non-cash exposure to an asset, index, rate or instrument. Leverage
can increase both the risk and return potential of the Fund. The Fund is required to segregate liquid assets or otherwise cover
the Fund’s obligation created by a transaction that may give rise to leverage. The use of leverage may cause the Fund to
liquidate portfolio positions when it may not be advantageous to do so to satisfy its obligations or to meet segregation requirements.
Leverage may cause the Fund’s share price to be more volatile than if it had not been leveraged, as certain types of leverage
may exaggerate the effect of any increase or decrease in the value of the Fund’s portfolio securities. The loss on leveraged
investments may substantially exceed the initial investment.
Risks Associated with Active Management. The
success of the Fund’s investment strategy depends on portfolio management’s successful application of analytical skills
and investment judgment. Active management involves subjective decisions.
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(s). 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.
