Expense Example Narrative [Text Block]

Each Strategy's operating expense table shows the fees and expenses (including the pro rata share of expenses of the Underlying Portfolio for the Strategies that invest in them) that you may pay if you buy and hold shares of a Strategy. The Examples are intended to help you compare the cost of investing in the Strategies with the cost of investing in other funds. They assume that you invest $10,000 in a Strategy for the time periods indicated and then redeem all of your shares at the end of those periods. They also assume that your investment has a 5% return each year, that the Strategy's operating expenses stay the same and that all dividends and distributions are reinvested. Although your actual costs may be higher or lower, based on these assumptions your costs as reflected in the Examples would be:

OBJECTIVE AND PRINCIPAL STRATEGIES:

Strategy Narrative [Text Block]

The Strategy's investment objective is long-term growth of capital.

The Strategy seeks to achieve its objective by investing in a combination of Underlying Portfolios representing a variety of asset classes and investment styles that are also managed by the Adviser. By allocating its assets among the Underlying Portfolios, the Strategy creates a portfolio that is designed as a solution for investors who seek equity returns without regard to taxes but also want broad diversification of the related risks across styles, capitalization ranges and geographic regions. Through investments in the Underlying Portfolios, the Adviser efficiently diversifies the Strategy between growth and value equity investment styles, and between U.S. and non-U.S. markets. Normally, the Strategy's targeted blend is an equal weighting of growth and value style Underlying Portfolios (50% each).

The following table shows the target percentages of its net assets that the Strategy will invest in each of the Underlying Portfolios indicated as of the date of this Prospectus.

Asset Class - Stock

Underlying Portfolio

U.S. Large Cap Growth - 24%

U.S. Value - 24%

U.S. Small/Mid Cap Growth - 7.5%

U.S. Small/Mid-Cap Value - 7.5%

International Growth - 13.5%

International Value - 13.5%

Asset Class - Real Estate

Global Real Estate - 10%

In addition to blending growth and value styles, the Strategy blends each style component across Underlying Portfolios that invest in U.S. and non-U.S. companies and various capitalization ranges. Within each of the value and growth components, the Strategy's targeted blend is approximately 70% in Underlying Portfolios that invest in U.S. companies and the remaining 30% in Underlying Portfolios that invest in non-U.S. companies. The Adviser will allow the relative weightings of the Strategy's investments in growth and value and U.S. and non-U.S. Underlying Portfolios to vary in response to markets, but ordinarily only by ±5% of the Strategy's net assets. Beyond those ranges, the Adviser will generally rebalance the portfolio toward the targeted blend. However, under extraordinary circumstances, such as when market conditions favoring one investment component are compelling, the range may expand to 10% of the Strategy's net assets. The Strategy's targeted blend may change from time to time without notice to shareholders based on the Adviser's assessment of market conditions.

In managing the Underlying Portfolios, the Adviser selects growth and value equity securities by drawing from a variety of its fundamental growth and value investment disciplines to produce a blended portfolio. Within each investment discipline, the Adviser is able to draw on the resources and expertise of multiple growth and value equity investment teams, specializing in different capitalization ranges and geographic regions (U.S. and non-U.S.), which are supported by more than 50 equity research analysts specializing in growth research, and more than 50 equity research analysts specializing in value research.

Each growth investment team selects stocks using a process that seeks to identify companies with strong management, superior industry positions, excellent balance sheets and superior earnings growth prospects. This discipline relies heavily upon the fundamental analysis and research of the Adviser's large internal growth research staff, which follows over 1,500 U.S. and non-U.S. companies. The Adviser's growth analysts prepare their own earnings estimates and financial models for each company followed. Research emphasis is placed on identifying companies whose substantially above-average prospective earnings growth is not fully reflected in current market valuations. Each growth investment team constructs a portfolio that emphasizes equity securities of a limited number of carefully selected, high-quality companies that are judged likely to achieve superior earnings growth.

Each value investment team seeks to identify companies whose long-term earning power and dividend paying capability are not reflected in the current market price of their securities. This fundamental value discipline relies heavily upon the large internal value research staff of the Adviser's Bernstein unit ("Bernstein"), which follows over 1,500 U.S. and non-U.S. companies. Teams within the value research staff cover a given industry worldwide, to better understand each company's competitive position in a global context. Bernstein's staff of company and industry analysts prepares its own earnings estimates and financial models for each company analyzed. Bernstein identifies and quantifies the critical variables that control a business's performance and analyzes the results in order to forecast each company's long-term prospects and expected returns. Through application of this value investment process, each value investment team constructs a portfolio that emphasizes equity securities of a limited number of value companies.

PRINCIPAL RISKS:
RISKS SUMMARY

Risk Narrative [Text Block]

* Market Risk

* Foreign (Non-U.S.) Risk

* Currency Risk

* Capitalization Risk
Please see "Risks Summary" for a description of these and other risks of investing in the Strategy.

In this Summary, we describe the principal and other risks thatmay affect a Strategy's portfolio (including the UnderlyingPortfolios for those Strategies investing in Underlying Portfolios)as a whole.
MARKET RISK This is the risk that the value of a Strategy's investments will fluctuate as the stock or bond markets fluctuate and that prices overall will decline over short- or long-term periods. It includes the risk that a particular style of investing, such as growth, may be underperforming the stock market generally.
INFLATION RISK This is the risk that the value of assets or income from investments will be less in the future as inflation decreases the value of money. As inflation increases, the value of each Strategy's assets can decline as can the value of the Strategy's distributions. This risk is significantly greater for those Strategies that invest a significant portion of their assets in fixed-income securities with longer maturities.
ALLOCATION RISK The allocation of investments among the Underlying Portfolios, different investment styles, such as growth or value, equity and debt securities, or U.S. and non-U.S. securities may have a more significant effect on a Strategy's net asset value, or NAV, when one of these investment strategies is performing more poorly than others.
FOREIGN (NON-U.S.) RISK A Strategy's investments in securities of non-U.S. issuers may experience more rapid and extreme changes in value than investments in securities of U.S. companies. The securities markets of many foreign countries are relatively small, with a limited number of companies representing a small number of securities. Non-U.S. issuers usually are not subject to the same degree of regulation as U.S. issuers. Reporting, accounting and auditing standards of foreign countries differ, in some cases significantly,from U.S. standards. Nationalization, expropriation or confiscatory taxation, currency blockage or political changes or diplomatic developments could adversely affect a Strategy's investments in a country other than the United States. To the extent a Strategy invests in a particular country or geographicregion, the Strategy may have more significant risk due to market changes or other factors affecting that country or region, including political instability and unpredictable economic conditions.
EMERGING MARKET RISK Foreign investment risk may be particularly high to the extent a Strategy invests in emerging market securities of issuers based in countries with developing economies. These securities may present market, credit, currency, liquidity, legal, political and other risks different from, or greater than, the risks of investing in developed foreign (non-U.S.) countries.
CURRENCY RISK This is the risk that changes in foreign (non-U.S.) currencyexchange rates may negatively affect the value of a Strategy's investments or reduce the returns of a Strategy. For example, the value of a Strategy's investments in foreign stocks or currencies may decrease if the U.S. Dollar is strong (i.e., gaining value relative to other currencies) and other currencies areweak (i.e., losing value relative to the U.S. Dollar). Currency markets generally are not as regulated as securities markets.
CAPITALIZATION RISK This is the risk of investments in small- to mid-capitalization companies. Investments in small- and mid-cap companies may be more volatile than investments in large-cap companies. Investments in small cap companies tend to be more volatile than investments in mid- or large-cap companies. A Strategy's investments in smaller capitalization companies may have additional risks because these companies often have limited productlines, markets or financial resources.
INDUSTRY/SECTOR RISK This is the risk of investments in a particular industry or industry sector. Market or economic factors affecting that industryor group of related industries could have a major effect on the value of a Strategy's investments.
FOCUSED PORTFOLIO RISK This is the risk that investments in a limited number of companies may have more risk because changes in the value of a single security may have a more significant effect, either negative or positive, on the Strategy's NAV.
DERIVATIVES RISK The Strategies may use derivatives transactions. These investment strategies may be riskier than other investment strategies and may result in greater volatility for a Strategy, particularly during periods of market declines.
LEVERAGE RISK When a Strategy borrows money or otherwise leverages itsportfolio, it may be more volatile because leverage tends to exaggerate the effect of any increase or decrease in the value of a Strategy's investments. A Strategy may create leverage through the use of reverse repurchase arrangements, forward contracts or dollar rolls or by borrowing money.
LIQUIDITY RISK Liquidity risk exists when particular investments are difficult to purchase or sell, possibly preventing a Strategy from selling out of these illiquid securities at an advantageous time or price. Derivatives and securities involving substantial market and credit risk tend to involve greater liquidity risk.
MANAGEMENT RISK Each Strategy is subject to management risk because it is an actively managed investment portfolio. The Adviser will apply its investment techniques and risk analyses in making investment decisions for the Strategies, but there can be no guarantee that its techniques will produce the intended result.
