These transaction costs, which are not reflected in the Annual Strategy Operating Expenses or in the Examples, affect the Strategy's performance.

  <rr:StrategyNarrativeTextBlock contextRef="Duration_01Jan2012_31Dec2012S000010280_Member">The Strategy seeks the highest total return over time consistent with its asset mix. Total return includes capital growth and income. To achieve its investment objective, the Strategy invests in a combination of portfolios of The AllianceBernstein Pooling Portfolios representing a variety of asset classes and investment styles (the "Underlying Portfolios"). The Strategy is managed to the specific year of planned retirement included in its name (the "retirement date"). The Strategy's asset mixes will become more conservative each year until reaching the year approximately fifteen years after the retirement date (the "target year") at which time the asset allocation mix will become static. This reflects the objective of pursuing the maximum amount of capital growth, consistent with a reasonable amount of risk, during the investor's pre-retirement and early retirement years. After retirement the Strategy's investment mix anticipates that an investor may take withdrawals from his or her account to provide supplemental retirement income.&lt;br/&gt;&lt;br/&gt;After the retirement date of the Strategy, its asset mix seeks to minimize the likelihood that an investor in the Strategy experiences a significant loss of capital at a more advanced age. The asset mix for the Strategy will continue to change after the Strategy's retirement date with an increasing exposure to investments in fixed-income securities and short-term bonds until fifteen years after the Strategy's retirement date. Thereafter, the target asset allocation for the Strategy will generally be fixed. The static allocation of the Strategy's asset mix will be 27.5% short-duration bonds, 37.5% other fixed-income securities, 12.5% Volatility Management Portfolio, 15.5% other equities and 7% Multi-Asset Real Return Portfolio.&lt;br/&gt;&lt;br/&gt;The Underlying Portfolios will include a Portfolio, the Volatility Management Portfolio, that is designed to reduce the overall equity market volatility of the Strategy and the effects of adverse equity market conditions on its performance. The Volatility Management Portfolio will be a component of the Strategy's equity asset allocation. Under normal market conditions, this Underlying Portfolio will invest predominantly in equity securities. If the Adviser determines that the equity markets pose disproportionate risks, the Adviser will reduce (or eliminate) this Underlying Portfolio's equity investments and invest in fixed-income securities or other non-equity asset classes to reduce the risks of the Strategy's investments in equity securities.&lt;br/&gt;&lt;br/&gt;The Adviser will allow the relative weightings of the Strategy's asset classes to vary in response to the markets, but ordinarily only by plus/minus 5%. Beyond those ranges, the Adviser will generally rebalance the portfolio toward the target asset allocation for the Strategy. However, there may be occasions when those ranges will expand to 10% of the Strategy's portfolio due to, among other things, appreciation of one of the asset classes.&lt;br/&gt;&lt;br/&gt; The following chart illustrates how the asset mix of the Strategy will vary over time. In general, the asset mix of the Strategy will gradually shift from one comprised largely of Underlying Portfolios that emphasize investments in stocks to one that is comprised of a mixture of Underlying Portfolios that invest in bonds (including short-duration bonds) and stocks.&lt;br/&gt;&lt;br/&gt;

  <rr:PortfolioTurnoverTextBlock contextRef="Duration_01Jan2012_31Dec2012S000010282_Member">The Strategy (or an Underlying Portfolio) pays transaction costs, such as commissions, when it buys or sells securities (or &amp;#8220;turns over&amp;#8221; its portfolio). A higher portfolio turnover rate may indicate higher transaction costs and may result in higher taxes when Strategy shares are held in a taxable account. These transaction costs, which are not reflected in the Annual Strategy Operating Expenses or in the Examples, affect the Strategy&amp;#8217;s performance. During the most recent fiscal year, the Strategy&amp;#8217;s portfolio turnover rate (which reflects only purchases and sales of the Underlying Portfolios) was 19% of the average value of its portfolio.</rr:PortfolioTurnoverTextBlock>

  <rr:StrategyNarrativeTextBlock contextRef="Duration_01Jan2012_31Dec2012S000010282_Member">The Strategy seeks the highest total return over time consistent with its asset mix. Total return includes capital growth and income. To achieve its investment objective, the Strategy invests in a combination of portfolios of The AllianceBernstein Pooling Portfolios representing a variety of asset classes and investment styles (the "Underlying Portfolios"). The Strategy is managed to the specific year of planned retirement included in its name (the "retirement date"). The Strategy's asset mixes will become more conservative each year until reaching the year approximately fifteen years after the retirement date (the "target year") at which time the asset allocation mix will become static. This reflects the objective of pursuing the maximum amount of capital growth, consistent with a reasonable amount of risk, during the investor's pre-retirement and early retirement years. After retirement the Strategy's investment mix anticipates that an investor may take withdrawals from his or her account to provide supplemental retirement income.&lt;br/&gt;&lt;br/&gt;After the retirement date of the Strategy, its asset mix seeks to minimize the likelihood that an investor in the Strategy experiences a significant loss of capital at a more advanced age. The asset mix for the Strategy will continue to change after the Strategy's retirement date with an increasing exposure to investments in fixed-income securities and short-term bonds until fifteen years after the Strategy's retirement date. Thereafter, the target asset allocation for the Strategy will generally be fixed. The static allocation of the Strategy's asset mix will be 27.5% short-duration bonds, 37.5% other fixed-income securities, 12.5% Volatility Management Portfolio, 15.5% other equities and 7% Multi-Asset Real Return Portfolio.&lt;br/&gt;&lt;br/&gt;The Underlying Portfolios will include a Portfolio, the Volatility Management Portfolio, that is designed to reduce the overall effect of equity market volatility on the Strategy and the effects of adverse equity market conditions on its performance. The Volatility Management Portfolio will be a component of the Strategy's equity asset allocation. Under normal market conditions, this Underlying Portfolio will invest predominantly in equity securities. If the Adviser determines that the equity markets pose disproportionate risks, the Adviser will reduce (or eliminate) this Underlying Portfolio's equity investments and invest in fixed-income securities or other non-equity asset classes to reduce the risks of the Strategy's investments in equity securities.&lt;br/&gt;&lt;br/&gt;The Adviser will allow the relative weightings of the Strategy's asset classes to vary in response to the markets, but ordinarily only by plus/minus 5%. Beyond those ranges, the Adviser will generally rebalance the portfolio toward the target asset allocation for the Strategy. However, there may be occasions when those ranges will expand to 10% of the Strategy's portfolio due to, among other things, appreciation of one of the asset classes.&lt;br/&gt;&lt;br/&gt; The following chart illustrates how the asset mix of the Strategy will vary over time. In general, the asset mix of the Strategy will gradually shift from one comprised largely of Underlying Portfolios that emphasize investments in stocks to one that is comprised of a mixture of Underlying Portfolios that invest in bonds (including short-duration bonds) and stocks.&lt;br/&gt;&lt;br/&gt;

  <rr:RiskHeading contextRef="Duration_01Jan2012_31Dec2012S000010282_Member">PRINCIPAL RISKS</rr:RiskHeading>
  <rr:RiskNarrativeTextBlock contextRef="Duration_01Jan2012_31Dec2012S000010282_Member">The value of your investment in the Strategy will change with changes in the values of the Strategy&amp;#8217;s investments in the Underlying Portfolios. There is no assurance that the Strategy will provide an investor with adequate income at or through retirement. The degree to which the following risks apply varies according to the Strategy&amp;#8217;s asset allocation.&lt;ul type="square"&gt;&lt;li style="margin-left: -20px"&gt;MARKET RISK: The value of the Strategy&amp;#8217;s investments will fluctuate as the stock or bond market fluctuates. The value of its investments may decline, sometimes rapidly and unpredictably, simply because of economic changes or other events that affect large portions of the market. It includes the risk that a particular style of investing, such as growth or value, may be underperforming the stock market generally.&lt;/li&gt;&lt;/ul&gt;&lt;ul type="square"&gt;&lt;li style="margin-left: -20px"&gt;INTEREST RATE RISK: Changes in interest rates will affect the value of the Strategy&amp;#8217;s investments in Underlying Portfolios that invest in fixed-income securities. When interest rates rise, the value of investments in fixed-income securities tends to fall and this decrease in value may not be offset by higher income from new investments. Interest rate risk is generally greater for fixed-income securities with longer maturities or durations. Investments in fixed-income securities with lower credit ratings ("junk bonds") tend to have a higher probability that an issuer will default or fail to meet its payment obligations.&lt;/li&gt;&lt;/ul&gt;&lt;ul type="square"&gt;&lt;li style="margin-left: -20px"&gt;CREDIT RISK: An issuer or guarantor of a fixed-income security, or the counterparty to a derivatives or other contract, may be unable or unwilling to make timely payments of interest or principal, or to otherwise honor its obligations. The issuer or guarantor may default, causing a loss of the full principal amount of a security. The degree of risk for a particular security may be reflected in its credit rating. There is the possibility that the credit rating of a fixed-income security may be downgraded after purchase, which may adversely affect the value of the security. Investments in fixed-income securities with lower ratings tend to have a higher probability that an issuer will default or fail to meet its payment obligations.&lt;/li&gt;&lt;/ul&gt;&lt;ul type="square"&gt;&lt;li style="margin-left: -20px"&gt;ALLOCATION RISK: The allocation of investments among the Underlying Portfolios&amp;#8217; different investment styles, such as growth or value, equity or debt securities, or U.S. or non-U.S. securities, may have a more significant effect on the Strategy&amp;#8217;s NAV when one of these investments is performing more poorly than the other.&lt;/li&gt;&lt;/ul&gt;&lt;ul type="square"&gt;&lt;li style="margin-left: -20px"&gt;INFLATION RISK: This is the risk that the value of assets or income from the Strategy&amp;#8217;s investments in the Underlying Portfolios will be less in the future as inflation decreases the value of money. As inflation increases, the value of each Underlying Portfolio&amp;#8217;s assets can decline as can the value of that Underlying Portfolio&amp;#8217;s distributions.&lt;/li&gt;&lt;/ul&gt;&lt;ul type="square"&gt;&lt;li style="margin-left: -20px"&gt;FOREIGN (NON-U.S.) RISK: The Strategy&amp;#8217;s investments in Underlying Portfolios that invest in securities of non-U.S. issuers may experience more rapid and extreme changes in value than investments in securities of U.S. issuers. These securities may fluctuate more widely in price and may be less liquid due to adverse market, economic, political, regulatory or other factors. This risk is greater when the Strategy has a higher asset allocation of Underlying Portfolios that invest in non-U.S. issuers.&lt;/li&gt;&lt;/ul&gt;&lt;ul type="square"&gt;&lt;li style="margin-left: -20px"&gt;EMERGING MARKET RISK: Investments in emerging market countries may involve more risk than investments in other foreign countries because the markets in emerging market countries are less developed and less liquid as well as subject to increased economic, political, regulatory and other uncertainties.&lt;/li&gt;&lt;/ul&gt;&lt;ul type="square"&gt;&lt;li style="margin-left: -20px"&gt;CURRENCY RISK: Fluctuations in currency exchange rates may negatively affect the value of the Strategy&amp;#8217;s investments or reduce its returns.&lt;/li&gt;&lt;/ul&gt;&lt;ul type="square"&gt;&lt;li style="margin-left: -20px"&gt;CAPITALIZATION RISK: Investments in small- and mid-capitalization companies by Underlying Portfolios tend to be more volatile than investments in large-capitalization companies. Investments in small-capitalization companies may have additional risks because these companies often have limited product lines, markets, or financial resources.&lt;/li&gt;&lt;/ul&gt;&lt;ul type="square"&gt;&lt;li style="margin-left: -20px"&gt;FOCUSED PORTFOLIO RISK: The Underlying Portfolios that invest 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&amp;#8217;s NAV.&lt;/li&gt;&lt;/ul&gt;&lt;ul type="square"&gt;&lt;li style="margin-left: -20px"&gt;DERIVATIVES RISK: Investments in derivatives may be illiquid, difficult to price, and leveraged so that small changes may produce disproportionate losses, and may be subject to counterparty risk to a greater degree than more traditional investments.&lt;/li&gt;&lt;/ul&gt;&lt;ul type="square"&gt;&lt;li style="margin-left: -20px"&gt;LEVERAGE RISK: Borrowing money or other leverage may make an Underlying Portfolio&amp;#8217;s investments more volatile because leverage tends to exaggerate the effect of any increase or decrease in the value of its investments. An Underlying Portfolio may create leverage through the use of certain portfolio management techniques such as reverse repurchase agreements or forward commitments, or by borrowing money.&lt;/li&gt;&lt;/ul&gt;&lt;ul type="square"&gt;&lt;li style="margin-left: -20px"&gt;MANAGEMENT RISK: The Strategy is subject to management risk because it is an actively managed investment fund. The Adviser will apply its investment techniques and risk analyses in making investment decisions for the Strategy, but there is no guarantee that its techniques will produce the intended results.&lt;/li&gt;&lt;/ul&gt;As with all investments, you may lose money by investing in the Strategy.</rr:RiskNarrativeTextBlock>

  <rr:RiskNarrativeTextBlock contextRef="Duration_01Jan2012_31Dec2012S000010280_Member">The value of your investment in the Strategy will change with changes in the values of the Strategy's investments in the Underlying Portfolios. There is no assurance that the Strategy will provide an investor with adequate income at or through retirement. The degree to which the following risks apply varies according to the Strategy's asset allocation.&lt;ul type="square"&gt;&lt;li style="margin-left:-20px"&gt;MARKET RISK: The value of the Strategy's investments will fluctuate as the stock or bond market fluctuates. The value of its investments may decline, sometimes rapidly and unpredictably, simply because of economic changes or other events that affect large portions of the market. It includes the risk that a particular style of investing, such as growth or value, may be underperforming the stock market generally.&lt;/li&gt;&lt;/ul&gt;&lt;ul type="square"&gt;&lt;li style="margin-left:-20px"&gt;INTEREST RATE RISK: Changes in interest rates will affect the value of the Strategy's investments in Underlying Portfolios that invest in fixed-income securities. When interest rates rise, the value of investments in fixed-income securities tends to fall and this decrease in value may not be offset by higher income from new investments. Interest rate risk is generally greater for fixed-income securities with longer maturities or durations. Investments in fixed-income securities with lower credit ratings ("junk bonds") tend to have a higher probability that an issuer will default or fail to meet its payment obligations.&lt;/li&gt;&lt;/ul&gt;&lt;ul type="square"&gt;&lt;li style="margin-left:-20px"&gt;CREDIT RISK: An issuer or guarantor of a fixed-income security, or the counterparty to a derivatives or other contract, may be unable or unwilling to make timely payments of interest or principal, or to otherwise honor its obligations. The issuer or guarantor may default, causing a loss of the full principal amount of a security. The degree of risk for a particular security may be reflected in its credit rating. There is the possibility that the credit rating of a fixed-income security may be downgraded after purchase, which may adversely affect the value of the security. Investments in fixed-income securities with lower ratings tend to have a higher probability that an issuer will default or fail to meet its payment obligations.&lt;/li&gt;&lt;/ul&gt;&lt;ul type="square"&gt;&lt;li style="margin-left:-20px"&gt;ALLOCATION RISK: The allocation of investments among the Underlying Portfolios' different investment styles, such as growth or value, equity or debt securities, or U.S. or non-U.S. securities, may have a more significant effect on the Strategy's NAV when one of these investments is performing more poorly than the other.&lt;/li&gt;&lt;/ul&gt;&lt;ul type="square"&gt;&lt;li style="margin-left:-20px"&gt;INFLATION RISK: This is the risk that the value of assets or income from the Strategy's investments in the Underlying Portfolios will be less in the future as inflation decreases the value of money. As inflation increases, the value of each Underlying Portfolio's assets can decline as can the value of that Underlying Portfolio's distributions.&lt;/li&gt;&lt;/ul&gt;&lt;ul type="square"&gt;&lt;li style="margin-left:-20px"&gt;FOREIGN (NON-U.S.) RISK: The Strategy's investments in Underlying Portfolios that invest in securities of non-U.S. issuers may experience more rapid and extreme changes in value than investments in securities of U.S. issuers. These securities may fluctuate more widely in price and may be less liquid due to adverse market, economic, political, regulatory or other factors. This risk is greater when the Strategy has a higher asset allocation of Underlying Portfolios that invest in non-U.S. issuers.&lt;/li&gt;&lt;/ul&gt;&lt;ul type="square"&gt;&lt;li style="margin-left:-20px"&gt;EMERGING MARKET RISK: Investments in emerging market countries may involve more risk than investments in other foreign countries because the markets in emerging market countries are less developed and less liquid as well as subject to increased economic, political, regulatory and other uncertainties.&lt;/li&gt;&lt;/ul&gt;&lt;ul type="square"&gt;&lt;li style="margin-left:-20px"&gt;CURRENCY RISK: Fluctuations in currency exchange rates may negatively affect the value of the Strategy's investments or reduce its returns.&lt;/li&gt;&lt;/ul&gt;&lt;ul type="square"&gt;&lt;li style="margin-left:-20px"&gt;CAPITALIZATION RISK: Investments in small- and mid-capitalization companies by Underlying Portfolios tend to be more volatile than investments in large-capitalization companies. Investments in small-capitalization companies may have additional risks because these companies often have limited product lines, markets, or financial resources.&lt;/li&gt;&lt;/ul&gt;&lt;ul type="square"&gt;&lt;li style="margin-left:-20px"&gt;FOCUSED PORTFOLIO RISK: The Underlying Portfolios that invest 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.&lt;/li&gt;&lt;/ul&gt;&lt;ul type="square"&gt;&lt;li style="margin-left:-20px"&gt;DERIVATIVES RISK: Investments in derivatives may be illiquid, difficult to price, and leveraged so that small changes may produce disproportionate losses, and may be subject to counterparty risk to a greater degree than more traditional investments. &lt;/li&gt;&lt;/ul&gt;&lt;ul type="square"&gt;&lt;li style="margin-left:-20px"&gt;LEVERAGE RISK: Borrowing money or other leverage may make an Underlying Portfolio's investments more volatile because leverage tends to exaggerate the effect of any increase or decrease in the value of its investments. An Underlying Portfolio may create leverage through the use of certain portfolio management techniques such as reverse repurchase agreements or forward commitments, or by borrowing money.&lt;/li&gt;&lt;/ul&gt;&lt;ul type="square"&gt;&lt;li style="margin-left:-20px"&gt;MANAGEMENT RISK: The Strategy is subject to management risk because it is an actively managed investment fund. The Adviser will apply its investment techniques and risk analyses in making investment decisions for the Strategy, but there is no guarantee that its techniques will produce the intended results.&lt;/li&gt;&lt;/ul&gt;As with all investments, you may lose money by investing in the Strategy.</rr:RiskNarrativeTextBlock>

  <rr:PortfolioTurnoverTextBlock contextRef="Duration_01Jan2012_31Dec2012S000010275_Member">The Strategy (or an Underlying Portfolio) pays transaction costs, such as commissions, when it buys or sells securities (or "turns over" its portfolio). A higher portfolio turnover rate may indicate higher transaction costs and may result in higher taxes when Strategy shares are held in a taxable account. These transaction costs, which are not reflected in the Annual Strategy Operating Expenses or in the Examples, affect the Strategy's performance. During the most recent fiscal year, the Strategy's portfolio turnover rate (which reflects only purchases and sales of the Underlying Portfolios) was 43% of the average value of its portfolio.</rr:PortfolioTurnoverTextBlock>

  <rr:StrategyNarrativeTextBlock contextRef="Duration_01Jan2012_31Dec2012S000010275_Member">The Strategy seeks the highest total return over time consistent with its asset mix. Total return includes capital growth and income. To achieve its investment objective, the Strategy invests in a combination of portfolios of The AllianceBernstein Pooling Portfolios representing a variety of asset classes and investment styles (the "Underlying Portfolios"). The Strategy is managed to the specific year of planned retirement included in its name (the "retirement date"). The Strategy's asset mixes will become more conservative each year until reaching the year approximately fifteen years after the retirement date (the "target year") at which time the asset allocation mix will become static. This reflects the objective of pursuing the maximum amount of capital growth, consistent with a reasonable amount of risk, during the investor's pre-retirement and early retirement years. After retirement the Strategy's investment mix anticipates that an investor may take withdrawals from his or her account to provide supplemental retirement income.&lt;br/&gt;&lt;br/&gt; After the retirement date of the Strategy, its asset mix seeks to minimize the likelihood that an investor in the Strategy experiences a significant loss of capital at a more advanced age. The asset mix for the Strategy will continue to change after the Strategy's retirement date with an increasing exposure to investments in fixed-income securities and short-term bonds until fifteen years after the Strategy's retirement date. Thereafter, the target asset allocation for the Strategy will generally be fixed. The static allocation of the Strategy's asset mix will be 27.5% short-duration bonds, 37.5% other fixed-income securities, 12.5% Volatility Management Portfolio, 15.5% other equities and 7% Multi-Asset Real Return Portfolio.&lt;br/&gt;&lt;br/&gt; The Underlying Portfolios will include a Portfolio, the Volatility Management Portfolio, that is designed to reduce the overall effect of equity market volatility on the Strategy and the effects of adverse equity market conditions on its performance. The Volatility Management Portfolio will be a component of the Strategy's equity asset allocation. Under normal market conditions, this Underlying Portfolio will invest predominantly in equity securities. If the Adviser determines that the equity markets pose disproportionate risks, the Adviser will reduce (or eliminate) this Underlying Portfolio's equity investments and invest in fixed-income securities or other non-equity asset classes to reduce the risks of the Strategy's investments in equity securities.&lt;br/&gt;&lt;br/&gt; The Adviser will allow the relative weightings of the Strategy's asset classes to vary in response to the markets, but ordinarily only by plus/minus 5%. Beyond those ranges, the Adviser will generally rebalance the portfolio toward the target asset allocation for the Strategy. However, there may be occasions when those ranges will expand to 10% of the Strategy's portfolio due to, among other things, appreciation of one of the asset classes.&lt;br/&gt;&lt;br/&gt;The following chart illustrates how the asset mix of the Strategy will vary over time. In general, the asset mix of the Strategy will gradually shift from one comprised largely of Underlying Portfolios that emphasize investments in stocks to one that is comprised of a mixture of Underlying Portfolios that invest in bonds (including short-duration bonds) and stocks.&lt;br/&gt;&lt;br/&gt;

  <rr:RiskHeading contextRef="Duration_01Jan2012_31Dec2012S000010275_Member">PRINCIPAL RISKS</rr:RiskHeading>
  <rr:RiskNarrativeTextBlock contextRef="Duration_01Jan2012_31Dec2012S000010275_Member">The value of your investment in the Strategy will change with changes in the values of the Strategy's investments in the Underlying Portfolios. There is no assurance that the Strategy will provide an investor with adequate income at or through retirement. The degree to which the following risks apply varies according to the Strategy's asset allocation.&lt;ul type="square"&gt;&lt;li style="margin-left:-20px"&gt;MARKET RISK: The value of the Strategy's investments will fluctuate as the stock or bond market fluctuates. The value of its investments may decline, sometimes rapidly and unpredictably, simply because of economic changes or other events that affect large portions of the market. It includes the risk that a particular style of investing, such as growth or value, may be underperforming the stock market generally.&lt;/li&gt;&lt;/ul&gt;&lt;ul type="square"&gt;&lt;li style="margin-left:-20px"&gt;INTEREST RATE RISK: Changes in interest rates will affect the value of the Strategy's investments in Underlying Portfolios that invest in fixed-income securities. When interest rates rise, the value of investments in fixed-income securities tends to fall and this decrease in value may not be offset by higher income from new investments. Interest rate risk is generally greater for fixed-income securities with longer maturities or durations. Investments in fixed-income securities with lower credit ratings ("junk bonds") tend to have a higher probability that an issuer will default or fail to meet its payment obligations.&lt;/li&gt;&lt;/ul&gt;&lt;ul type="square"&gt;&lt;li style="margin-left:-20px"&gt;CREDIT RISK: An issuer or guarantor of a fixed-income security, or the counterparty to a derivatives or other contract, may be unable or unwilling to make timely payments of interest or principal, or to otherwise honor its obligations. The issuer or guarantor may default, causing a loss of the full principal amount of a security. The degree of risk for a particular security may be reflected in its credit rating. There is the possibility that the credit rating of a fixed-income security may be downgraded after purchase, which may adversely affect the value of the security. Investments in fixed-income securities with lower ratings tend to have a higher probability that an issuer will default or fail to meet its payment obligations.&lt;/li&gt;&lt;/ul&gt;&lt;ul type="square"&gt;&lt;li style="margin-left:-20px"&gt;ALLOCATION RISK: The allocation of investments among the Underlying Portfolios' different investment styles, such as growth or value, equity or debt securities, or U.S. or non-U.S. securities, may have a more significant effect on the Strategy's net asset value ("NAV") when one of these investments is performing more poorly than the other.&lt;/li&gt;&lt;/ul&gt;&lt;ul type="square"&gt;&lt;li style="margin-left:-20px"&gt;INFLATION RISK: This is the risk that the value of assets or income from the Strategy's investments in the Underlying Portfolios will be less in the future as inflation decreases the value of money. As inflation increases, the value of each Underlying Portfolio's assets can decline as can the value of that Underlying Portfolio's distributions.&lt;/li&gt;&lt;/ul&gt;&lt;ul type="square"&gt;&lt;li style="margin-left:-20px"&gt;FOREIGN (NON-U.S.) RISK: The Strategy's investments in Underlying Portfolios that invest in securities of non-U.S. issuers may experience more rapid and extreme changes in value than investments in securities of U.S. issuers. These securities may fluctuate more widely in price and may be less liquid due to adverse market, economic, political, regulatory or other factors. This risk is greater when the Strategy has a higher asset allocation of Underlying Portfolios that invest in non-U.S. issuers.&lt;/li&gt;&lt;/ul&gt;&lt;ul type="square"&gt;&lt;li style="margin-left:-20px"&gt;EMERGING MARKET RISK: Investments in emerging market countries may involve more risk than investments in other foreign countries because the markets in emerging market countries are less developed and less liquid as well as subject to increased economic, political, regulatory and other uncertainties.&lt;/li&gt;&lt;/ul&gt;&lt;ul type="square"&gt;&lt;li style="margin-left:-20px"&gt;CURRENCY RISK: Fluctuations in currency exchange rates may negatively affect the value of the Strategy's investments or reduce its returns.&lt;/li&gt;&lt;/ul&gt;&lt;ul type="square"&gt;&lt;li style="margin-left:-20px"&gt;CAPITALIZATION RISK: Investments in small-and mid-capitalization companies by Underlying Portfolios tend to be more volatile than investments in large-capitalization companies. Investments in small-capitalization companies may have additional risks because these companies often have limited product lines, markets, or financial resources.&lt;/li&gt;&lt;/ul&gt;&lt;ul type="square"&gt;&lt;li style="margin-left:-20px"&gt;FOCUSED PORTFOLIO RISK: The Underlying Portfolios that invest 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.&lt;/li&gt;&lt;/ul&gt;&lt;ul type="square"&gt;&lt;li style="margin-left:-20px"&gt;DERIVATIVES RISK: Investments in derivatives may be illiquid, difficult to price, and leveraged so that small changes may produce disproportionate losses, and may be subject to counterparty risk to a greater degree than more traditional investments. &lt;/li&gt;&lt;/ul&gt;&lt;ul type="square"&gt;&lt;li style="margin-left:-20px"&gt;LEVERAGE RISK: Borrowing money or other leverage may make an Underlying Portfolio's investments more volatile because leverage tends to exaggerate the effect of any increase or decrease in the value of its investments. An Underlying Portfolio may create leverage through the use of certain portfolio management techniques such as reverse repurchase agreements or forward commitments, or by borrowing money.&lt;/li&gt;&lt;/ul&gt;&lt;ul type="square"&gt;&lt;li style="margin-left:-20px"&gt;MANAGEMENT RISK: The Strategy is subject to management risk because it is an actively managed investment fund. The Adviser will apply its investment techniques and risk analyses in making investment decisions for the Strategy, but there is no guarantee that its techniques will produce the intended results.&lt;/li&gt;&lt;/ul&gt;As with all investments, you may lose money by investing in the Strategy.</rr:RiskNarrativeTextBlock>

  <rr:StrategyNarrativeTextBlock contextRef="Duration_01Jan2012_31Dec2012S000010284_Member">The Strategy seeks the highest total return over time consistent with its asset mix. Total return includes capital growth and income. To achieve its investment objective, the Strategy invests in a combination of portfolios of The AllianceBernstein Pooling Portfolios representing a variety of asset classes and investment styles (the "Underlying Portfolios"). The Strategy is managed to the specific year of planned retirement included in its name (the "retirement date"). The Strategy's asset mixes will become more conservative each year until reaching the year approximately fifteen years after the retirement date (the "target year") at which time the asset allocation mix will become static. This reflects the objective of pursuing the maximum amount of capital growth, consistent with a reasonable amount of risk, during the investor's pre-retirement and early retirement years. After retirement the Strategy's investment mix anticipates that an investor may take withdrawals from his or her account to provide supplemental retirement income.&lt;br/&gt;&lt;br/&gt;After the retirement date of the Strategy, its asset mix seeks to minimize the likelihood that an investor in the Strategy experiences a significant loss of capital at a more advanced age. The asset mix for the Strategy will continue to change after the Strategy's retirement date with an increasing exposure to investments in fixed-income securities and short-term bonds until fifteen years after the Strategy's retirement date. Thereafter, the target asset allocation for the Strategy will generally be fixed. The static allocation of the Strategy's asset mix will be 27.5% short-duration bonds, 37.5% other fixed-income securities, 12.5% Volatility Management Portfolio, 15.5% other equities and 7% Multi-Asset Real Return Portfolio.&lt;br/&gt;&lt;br/&gt;The Underlying Portfolios will include a Portfolio, the Volatility Management Portfolio, that is designed to reduce the overall effect of equity market volatility on the Strategy and the effects of adverse equity market conditions on its performance. The Volatility Management Portfolio will be a component of the Strategy's equity asset allocation. Under normal market conditions, this Underlying Portfolio will invest predominantly in equity securities. If the Adviser determines that the equity markets pose disproportionate risks, the Adviser will reduce (or eliminate) this Underlying Portfolio's equity investments and invest in fixed-income securities or other non-equity asset classes to reduce the risks of the Strategy's investments in equity securities.&lt;br/&gt;&lt;br/&gt;The Adviser will allow the relative weightings of the Strategy's asset classes to vary in response to the markets, but ordinarily only by plus/minus 5%. Beyond those ranges, the Adviser will generally rebalance the portfolio toward the target asset allocation for the Strategy. However, there may be occasions when those ranges will expand to 10% of the Strategy's portfolio due to, among other things, appreciation of one of the asset classes.&lt;br/&gt;&lt;br/&gt;The following chart illustrates how the asset mix of the Strategy will vary over time. In general, the asset mix of the Strategy will gradually shift from one comprised largely of Underlying Portfolios that emphasize investments in stocks to one that is comprised of a mixture of Underlying Portfolios that invest in bonds (including short-duration bonds) and stocks.&lt;br/&gt;&lt;br/&gt;&lt;div&gt;

  <rr:RiskHeading contextRef="Duration_01Jan2012_31Dec2012S000010284_Member">PRINCIPAL RISKS</rr:RiskHeading>
  <rr:RiskNarrativeTextBlock contextRef="Duration_01Jan2012_31Dec2012S000010284_Member">The value of your investment in the Strategy will change with changes in the values of the Strategy's investments in the Underlying Portfolios. There is no assurance that the Strategy will provide an investor with adequate income at or through retirement. The degree to which the following risks apply varies according to the Strategy's asset allocation.&lt;ul type="square"&gt;&lt;li style="margin-left:-20px"&gt;MARKET RISK: The value of the Strategy's investments will fluctuate as the stock or bond market fluctuates. The value of its investments may decline, sometimes rapidly and unpredictably, simply because of economic changes or other events that affect large portions of the market. It includes the risk that a particular style of investing, such as growth or value, may be underperforming the stock market generally.&lt;/li&gt;&lt;/ul&gt;&lt;ul type="square"&gt;&lt;li style="margin-left:-20px"&gt;INTEREST RATE RISK: Changes in interest rates will affect the value of the Strategy's investments in Underlying Portfolios that invest in fixed-income securities. When interest rates rise, the value of investments in fixed-income securities tends to fall and this decrease in value may not be offset by higher income from new investments. Interest rate risk is generally greater for fixed-income securities with longer maturities or durations. Investments in fixed-income securities with lower credit ratings ("junk bonds") tend to have a higher probability that an issuer will default or fail to meet its payment obligations.&lt;/li&gt;&lt;/ul&gt;&lt;ul type="square"&gt;&lt;li style="margin-left:-20px"&gt;CREDIT RISK: An issuer or guarantor of a fixed-income security, or the counterparty to a derivatives or other contract, may be unable or unwilling to make timely payments of interest or principal, or to otherwise honor its obligations. The issuer or guarantor may default, causing a loss of the full principal amount of a security. The degree of risk for a particular security may be reflected in its credit rating. There is the possibility that the credit rating of a fixed-income security may be downgraded after purchase, which may adversely affect the value of the security. Investments in fixed-income securities with lower ratings tend to have a higher probability that an issuer will default or fail to meet its payment obligations.&lt;/li&gt;&lt;/ul&gt;&lt;ul type="square"&gt;&lt;li style="margin-left:-20px"&gt;ALLOCATION RISK: The allocation of investments among the Underlying Portfolios' different investment styles, such as growth or value, equity or debt securities, or U.S. or non-U.S. securities, may have a more significant effect on the Strategy's NAV when one of these investments is performing more poorly than the other.&lt;/li&gt;&lt;/ul&gt;&lt;ul type="square"&gt;&lt;li style="margin-left:-20px"&gt;INFLATION RISK: This is the risk that the value of assets or income from the Strategy's investments in the Underlying Portfolios will be less in the future as inflation decreases the value of money. As inflation increases, the value of each Underlying Portfolio's assets can decline as can the value of that Underlying Portfolio's distributions.&lt;/li&gt;&lt;/ul&gt;&lt;ul type="square"&gt;&lt;li style="margin-left:-20px"&gt;FOREIGN (NON-U.S.) RISK: The Strategy's investments in Underlying Portfolios that invest in securities of non-U.S. issuers may experience more rapid and extreme changes in value than investments in securities of U.S. issuers. These securities may fluctuate more widely in price and may be less liquid due to adverse market, economic, political, regulatory or other factors. This risk is greater when the Strategy has a higher asset allocation of Underlying Portfolios that invest in non-U.S. issuers.&lt;/li&gt;&lt;/ul&gt;&lt;ul type="square"&gt;&lt;li style="margin-left:-20px"&gt;EMERGING MARKET RISK: Investments in emerging market countries may involve more risk than investments in other foreign countries because the markets in emerging market countries are less developed and less liquid as well as subject to increased economic, political, regulatory and other uncertainties. &lt;/li&gt;&lt;/ul&gt;&lt;ul type="square"&gt;&lt;li style="margin-left:-20px"&gt; CURRENCY RISK: Fluctuations in currency exchange rates may negatively affect the value of the Strategy's investments or reduce its returns.&lt;/li&gt;&lt;/ul&gt;&lt;ul type="square"&gt;&lt;li style="margin-left:-20px"&gt;CAPITALIZATION RISK: Investments in small- and mid-capitalization companies by Underlying Portfolios tend to be more volatile than investments in large-capitalization companies. Investments in small-capitalization companies may have additional risks because these companies often have limited product lines, markets, or financial resources.&lt;/li&gt;&lt;/ul&gt;&lt;ul type="square"&gt;&lt;li style="margin-left:-20px"&gt;FOCUSED PORTFOLIO RISK: The Underlying Portfolios that invest 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.&lt;/li&gt;&lt;/ul&gt;&lt;ul type="square"&gt;&lt;li style="margin-left:-20px"&gt;DERIVATIVES RISK: Investments in derivatives may be illiquid, difficult to price, and leveraged so that small changes may produce disproportionate losses, and may be subject to counterparty risk to a greater degree than more traditional investments.&lt;/li&gt;&lt;/ul&gt;&lt;ul type="square"&gt;&lt;li style="margin-left:-20px"&gt;LEVERAGE RISK: Borrowing money or other leverage may make an Underlying Portfolio's investments more volatile because leverage tends to exaggerate the effect of any increase or decrease in the value of its investments. An Underlying Portfolio may create leverage through the use of certain portfolio management techniques such as reverse repurchase agreements or forward commitments, or by borrowing money.&lt;/li&gt;&lt;/ul&gt;&lt;ul type="square"&gt;&lt;li style="margin-left:-20px"&gt;MANAGEMENT RISK: The Strategy is subject to management risk because it is an actively managed investment fund. The Adviser will apply its investment techniques and risk analyses in making investment decisions for the Strategy, but there is no guarantee that its techniques will produce the intended results.&lt;/li&gt;&lt;/ul&gt;As with all investments, you may lose money by investing in the Strategy.</rr:RiskNarrativeTextBlock>

  <rr:StrategyNarrativeTextBlock contextRef="Duration_01Jan2012_31Dec2012S000010278_Member">The Strategy seeks the highest total return over time consistent with its asset mix. Total return includes capital growth and income. To achieve its investment objective, the Strategy invests in a combination of portfolios of The AllianceBernstein Pooling Portfolios representing a variety of asset classes and investment styles (the "Underlying Portfolios"). The Strategy is managed to the specific year of planned retirement included in its name (the "retirement date"). The Strategy's asset mixes will become more conservative each year until reaching the year approximately fifteen years after the retirement date (the "target year") at which time the asset allocation mix will become static. This reflects the objective of pursuing the maximum amount of capital growth, consistent with a reasonable amount of risk, during the investor's pre-retirement and early retirement years. After retirement the Strategy's investment mix anticipates that an investor may take withdrawals from his or her account to provide supplemental retirement income.&lt;br /&gt;&lt;br /&gt; After the retirement date of the Strategy, its asset mix seeks to minimize the likelihood that an investor in the Strategy experiences a significant loss of capital at a more advanced age. The asset mix for the Strategy will continue to change after the Strategy's retirement date with an increasing exposure to investments in fixed-income securities and short-term bonds until fifteen years after the Strategy's retirement date. Thereafter, the target asset allocation for the Strategy will generally be fixed. The static allocation of the Strategy's asset mix will be 27.5% short-duration bonds, 37.5% other fixed-income securities, 12.5% Volatility Management Portfolio, 15.5% other equities and 7% Multi-Asset Real Return Portfolio. &lt;br /&gt;&lt;br /&gt;The Underlying Portfolios will include a Portfolio, the Volatility Management Portfolio, that is designed to reduce the overall effect of equity market volatility on the Strategy and the effects of adverse equity market conditions on its performance. The Volatility Management Portfolio will be a component of the Strategy's equity asset allocation. Under normal market conditions, this Underlying Portfolio will invest predominantly in equity securities. If the Adviser determines that the equity markets pose disproportionate risks, the Adviser will reduce (or eliminate) this Underlying Portfolio's equity investments and invest in fixed-income securities or other non-equity asset classes to reduce the risks of the Strategy's investments in equity securities.&lt;br /&gt;&lt;br /&gt; The Adviser will allow the relative weightings of the Strategy's asset classes to vary in response to the markets, but ordinarily only by plus/minus 5%. Beyond those ranges, the Adviser will generally rebalance the portfolio toward the target asset allocation for the Strategy. However, there may be occasions when those ranges will expand to 10% of the Strategy's portfolio due to, among other things, appreciation of one of the asset classes.&lt;br /&gt;&lt;br /&gt; The following chart illustrates how the asset mix of the Strategy will vary over time. In general, the asset mix of the Strategy will gradually shift from one comprised largely of Underlying Portfolios that emphasize investments in stocks to one that is comprised of a mixture of Underlying Portfolios that invest in bonds (including short-duration bonds) and stocks.&lt;br /&gt;&lt;br /&gt;

  <rr:RiskHeading contextRef="Duration_01Jan2012_31Dec2012S000010278_Member">PRINCIPAL RISKS</rr:RiskHeading>
  <rr:RiskNarrativeTextBlock contextRef="Duration_01Jan2012_31Dec2012S000010278_Member">The value of your investment in the Strategy will change with changes in the values of the Strategy's investments in the Underlying Portfolios. There is no assurance that the Strategy will provide an investor with adequate income at or through retirement. The degree to which the following risks apply varies according to the Strategy's asset allocation. &lt;ul type="square"&gt;&lt;li style="margin-left:-20px"&gt; MARKET RISK: The value of the Strategy's investments will fluctuate as the stock or bond market fluctuates. The value of its investments may decline, sometimes rapidly and unpredictably, simply because of economic changes or other events that affect large portions of the market. It includes the risk that a particular style of investing, such as growth or value, may be underperforming the stock market generally.&lt;/li&gt;&lt;/ul&gt; &lt;ul type="square"&gt;&lt;li style="margin-left:-20px"&gt; INTEREST RATE RISK: Changes in interest rates will affect the value of the Strategy's investments in Underlying Portfolios that invest in fixed-income securities. When interest rates rise, the value of investments in fixed-income securities tends to fall and this decrease in value may not be offset by higher income from new investments. Interest rate risk is generally greater for fixed-income securities with longer maturities or durations. Investments in fixed-income securities with lower credit ratings ("junk bonds") tend to have a higher probability that an issuer will default or fail to meet its payment obligations.&lt;/li&gt;&lt;/ul&gt; &lt;ul type="square"&gt;&lt;li style="margin-left:-20px"&gt; CREDIT RISK: An issuer or guarantor of a fixed-income security, or the counterparty to a derivatives or other contract, may be unable or unwilling to make timely payments of interest or principal, or to otherwise honor its obligations. The issuer or guarantor may default, causing a loss of the full principal amount of a security. The degree of risk for a particular security may be reflected in its credit rating. There is the possibility that the credit rating of a fixed-income security may be downgraded after purchase, which may adversely affect the value of the security. Investments in fixed-income securities with lower ratings tend to have a higher probability that an issuer will default or fail to meet its payment obligations.&lt;/li&gt;&lt;/ul&gt; &lt;ul type="square"&gt;&lt;li style="margin-left:-20px"&gt; ALLOCATION RISK: The allocation of investments among the Underlying Portfolios' different investment styles, such as growth or value, equity or debt securities, or U.S. or non-U.S. securities, may have a more significant effect on the Strategy's NAV when one of these investments is performing more poorly than the other.&lt;/li&gt;&lt;/ul&gt; &lt;ul type="square"&gt;&lt;li style="margin-left:-20px"&gt; INFLATION RISK: This is the risk that the value of assets or income from the Strategy's investments in the Underlying Portfolios will be less in the future as inflation decreases the value of money. As inflation increases, the value of each Underlying Portfolio's assets can decline as can the value of that Underlying Portfolio's distributions.&lt;/li&gt;&lt;/ul&gt; &lt;ul type="square"&gt;&lt;li style="margin-left:-20px"&gt; FOREIGN (NON-U.S.) RISK: The Strategy's investments in Underlying Portfolios that invest in securities of non-U.S. issuers may experience more rapid and extreme changes in value than investments in securities of U.S. issuers. These securities may fluctuate more widely in price and may be less liquid due to adverse market, economic, political, regulatory or other factors. This risk is greater when the Strategy has a higher asset allocation of Underlying Portfolios that invest in non-U.S. issuers.&lt;/li&gt;&lt;/ul&gt; &lt;ul type="square"&gt;&lt;li style="margin-left:-20px"&gt; EMERGING MARKET RISK: Investments in emerging market countries may involve more risk than investments in other foreign countries because the markets in emerging market countries are less developed and less liquid as well as subject to increased economic, political, regulatory and other uncertainties.&lt;/li&gt;&lt;/ul&gt; &lt;ul type="square"&gt;&lt;li style="margin-left:-20px"&gt; CURRENCY RISK: Fluctuations in currency exchange rates may negatively affect the value of the Strategy's investments or reduce its returns.&lt;/li&gt;&lt;/ul&gt; &lt;ul type="square"&gt;&lt;li style="margin-left:-20px"&gt; CAPITALIZATION RISK: Investments in small- and mid-capitalization companies by Underlying Portfolios tend to be more volatile than investments in large-capitalization companies. Investments in small-capitalization companies may have additional risks because these companies often have limited product lines, markets, or financial resources.&lt;/li&gt;&lt;/ul&gt; &lt;ul type="square"&gt;&lt;li style="margin-left:-20px"&gt; FOCUSED PORTFOLIO RISK: The Underlying Portfolios that invest 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.&lt;/li&gt;&lt;/ul&gt; &lt;ul type="square"&gt;&lt;li style="margin-left:-20px"&gt; DERIVATIVES RISK: Investments in derivatives may be illiquid, difficult to price, and leveraged so that small changes may produce disproportionate losses, and may be subject to counterparty risk to a greater degree than more traditional investments.&lt;/li&gt;&lt;/ul&gt; &lt;ul type="square"&gt;&lt;li style="margin-left:-20px"&gt; LEVERAGE RISK: Borrowing money or other leverage may make an Underlying Portfolio's investments more volatile because leverage tends to exaggerate the effect of any increase or decrease in the value of its investments. An Underlying Portfolio may create leverage through the use of certain portfolio management techniques such as reverse repurchase agreements or forward commitments, or by borrowing money.&lt;/li&gt;&lt;/ul&gt; &lt;ul type="square"&gt;&lt;li style="margin-left:-20px"&gt; MANAGEMENT RISK: The Strategy is subject to management risk because it is an actively managed investment fund. The Adviser will apply its investment techniques and risk analyses in making investment decisions for the Strategy, but there is no guarantee that its techniques will produce the intended results. &lt;/li&gt;&lt;/ul&gt; As with all investments, you may lose money by investing in the Strategy.</rr:RiskNarrativeTextBlock>

These transaction costs, which are not reflected in the Annual Strategy Operating Expenses or in the Examples, affect the Strategy's performance.

  <rr:StrategyNarrativeTextBlock contextRef="Duration_01Jan2012_31Dec2012S000010283_Member">The Strategy seeks the highest total return over time consistent with its asset mix. Total return includes capital growth and income. To achieve its investment objective, the Strategy invests in a combination of portfolios of The AllianceBernstein Pooling Portfolios representing a variety of asset classes and investment styles (the &amp;#8220;Underlying Portfolios&amp;#8221;). The Strategy is managed to the specific year of planned retirement included in its name (the &amp;#8220;retirement date&amp;#8221;). The Strategy&amp;#8217;s asset mixes will become more conservative each year until reaching the year approximately fifteen years after the retirement date (the &amp;#8220;target year&amp;#8221;) at which time the asset allocation mix will become static. This reflects the objective of pursuing the maximum amount of capital growth, consistent with a reasonable amount of risk, during the investor&amp;#8217;s pre-retirement and early retirement years. After retirement the Strategy&amp;#8217;s investment mix anticipates that an investor may take withdrawals from his or her account to provide supplemental retirement income.&lt;br/&gt;&lt;br/&gt;After the retirement date of the Strategy, its asset mix seeks to minimize the likelihood that an investor in the Strategy experiences a significant loss of capital at a more advanced age. The asset mix for the Strategy will continue to change after the Strategy&amp;#8217;s retirement date with an increasing exposure to investments in fixed-income securities and short-term bonds until fifteen years after the Strategy&amp;#8217;s retirement date. Thereafter, the target asset allocation for the Strategy will generally be fixed. The static allocation of the Strategy&amp;#8217;s asset mix will be 27.5% short-duration bonds, 37.5% other fixed-income securities, 12.5% Volatility Management Portfolio, 15.5% other equities and 7% Multi-Asset Real Return Portfolio.&lt;br/&gt;&lt;br/&gt;The Underlying Portfolios will include a Portfolio, the Volatility Management Portfolio, that is designed to reduce the overall effect of equity market volatility on the Strategy and the effects of adverse equity market conditions on its performance. The Volatility Management Portfolio will be a component of the Strategy&amp;#8217;s equity asset allocation. Under normal market conditions, this Underlying Portfolio will invest predominantly in equity securities. If the Adviser determines that the equity markets pose disproportionate risks, the Adviser will reduce (or eliminate) this Underlying Portfolio&amp;#8217;s equity investments and invest in fixed-income securities or other non-equity asset classes to reduce the risks of the Strategy&amp;#8217;s investments in equity securities.&lt;br/&gt;&lt;br/&gt;The Adviser will allow the relative weightings of the Strategy&amp;#8217;s asset classes to vary in response to the markets, but ordinarily only by plus/minus 5%. Beyond those ranges, the Adviser will generally rebalance the portfolio toward the target asset allocation for the Strategy. However, there may be occasions when those ranges will expand to 10% of the Strategy&amp;#8217;s portfolio due to, among other things, appreciation of one of the asset classes.&lt;br/&gt;&lt;br/&gt;The following chart illustrates how the asset mix of the Strategy will vary over time. In general, the asset mix of the Strategy will gradually shift from one comprised largely of Underlying Portfolios that emphasize investments in stocks to one that is comprised of a mixture of Underlying Portfolios that invest in bonds (including short-duration bonds) and stocks.&lt;br/&gt;&lt;br/&gt;

  <rr:RiskHeading contextRef="Duration_01Jan2012_31Dec2012S000010283_Member">PRINCIPAL RISKS</rr:RiskHeading>
  <rr:RiskNarrativeTextBlock contextRef="Duration_01Jan2012_31Dec2012S000010283_Member">The value of your investment in the Strategy will change with changes in the values of the Strategy&amp;#8217;s investments in the Underlying Portfolios. There is no assurance that the Strategy will provide an investor with adequate income at or through retirement. The degree to which the following risks apply varies according to the Strategy&amp;#8217;s asset allocation.&lt;ul type="square"&gt;&lt;li style="margin-left: -20px"&gt;MARKET RISK: The value of the Strategy&amp;#8217;s investments will fluctuate as the stock or bond market fluctuates. The value of its investments may decline, sometimes rapidly and unpredictably, simply because of economic changes or other events that affect large portions of the market. It includes the risk that a particular style of investing, such as growth or value, may be underperforming the stock market generally.&lt;/li&gt;&lt;/ul&gt;&lt;ul type="square"&gt;&lt;li style="margin-left: -20px"&gt;INTEREST RATE RISK: Changes in interest rates will affect the value of the Strategy&amp;#8217;s investments in Underlying Portfolios that invest in fixed-income securities. When interest rates rise, the value of investments in fixed-income securities tends to fall and this decrease in value may not be offset by higher income from new investments. Interest rate risk is generally greater for fixed-income securities with longer maturities or durations. Investments in fixed-income securities with lower credit ratings ("junk bonds") tend to have a higher probability that an issuer will default or fail to meet its payment obligations.&lt;/li&gt;&lt;/ul&gt;&lt;ul type="square"&gt;&lt;li style="margin-left: -20px"&gt;CREDIT RISK: An issuer or guarantor of a fixed-income security, or the counterparty to a derivatives or other contract, may be unable or unwilling to make timely payments of interest or principal, or to otherwise honor its obligations. The issuer or guarantor may default, causing a loss of the full principal amount of a security. The degree of risk for a particular security may be reflected in its credit rating. There is the possibility that the credit rating of a fixed-income security may be downgraded after purchase, which may adversely affect the value of the security. Investments in fixed-income securities with lower ratings tend to have a higher probability that an issuer will default or fail to meet its payment obligations.&lt;/li&gt;&lt;/ul&gt;&lt;ul type="square"&gt;&lt;li style="margin-left: -20px"&gt;ALLOCATION RISK: The allocation of investments among the Underlying Portfolios&amp;#8217; different investment styles, such as growth or value, equity or debt securities, or U.S. or non-U.S. securities, may have a more significant effect on the Strategy&amp;#8217;s NAV when one of these investments is performing more poorly than the other.&lt;/li&gt;&lt;/ul&gt;&lt;ul type="square"&gt;&lt;li style="margin-left: -20px"&gt;INFLATION RISK: This is the risk that the value of assets or income from the Strategy&amp;#8217;s investments in the Underlying Portfolios will be less in the future as inflation decreases the value of money. As inflation increases, the value of each Underlying Portfolio&amp;#8217;s assets can decline as can the value of that Underlying Portfolio&amp;#8217;s distributions.&lt;/li&gt;&lt;/ul&gt;&lt;ul type="square"&gt;&lt;li style="margin-left: -20px"&gt;FOREIGN (NON-U.S.) RISK: The Strategy&amp;#8217;s investments in Underlying Portfolios that invest in securities of non-U.S. issuers may experience more rapid and extreme changes in value than investments in securities of U.S. issuers. These securities may fluctuate more widely in price and may be less liquid due to adverse market, economic, political, regulatory or other factors. This risk is greater when the Strategy has a higher asset allocation of Underlying Portfolios that invest in non-U.S. issuers.&lt;/li&gt;&lt;/ul&gt;&lt;ul type="square"&gt;&lt;li style="margin-left: -20px"&gt;EMERGING MARKET RISK: Investments in emerging market countries may involve more risk than investments in other foreign countries because the markets in emerging market countries are less developed and less liquid as well as subject to increased economic, political, regulatory and other uncertainties.&lt;/li&gt;&lt;/ul&gt;&lt;ul type="square"&gt;&lt;li style="margin-left: -20px"&gt;CURRENCY RISK: Fluctuations in currency exchange rates may negatively affect the value of the Strategy&amp;#8217;s investments or reduce its returns.&lt;/li&gt;&lt;/ul&gt;&lt;ul type="square"&gt;&lt;li style="margin-left: -20px"&gt;CAPITALIZATION RISK: Investments in small- and mid-capitalization companies by Underlying Portfolios tend to be more volatile than investments in large-capitalization companies. Investments in small-capitalization companies may have additional risks because these companies often have limited product lines, markets, or financial resources.&lt;/li&gt;&lt;/ul&gt;&lt;ul type="square"&gt;&lt;li style="margin-left: -20px"&gt;FOCUSED PORTFOLIO RISK: The Underlying Portfolios that invest 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&amp;#8217;s NAV.&lt;/li&gt;&lt;/ul&gt;&lt;ul type="square"&gt;&lt;li style="margin-left: -20px"&gt;DERIVATIVES RISK: Investments in derivatives may be illiquid, difficult to price, and leveraged so that small changes may produce disproportionate losses, and may be subject to counterparty risk to a greater degree than more traditional investments.&lt;/li&gt;&lt;/ul&gt;&lt;ul type="square"&gt;&lt;li style="margin-left: -20px"&gt;LEVERAGE RISK: Borrowing money or other leverage may make an Underlying Portfolio&amp;#8217;s investments more volatile because leverage tends to exaggerate the effect of any increase or decrease in the value of its investments. An Underlying Portfolio may create leverage through the use of certain portfolio management techniques such as reverse repurchase agreements or forward commitments, or by borrowing money.&lt;/li&gt;&lt;/ul&gt;&lt;ul type="square"&gt;&lt;li style="margin-left: -20px"&gt;MANAGEMENT RISK: The Strategy is subject to management risk because it is an actively managed investment fund. The Adviser will apply its investment techniques and risk analyses in making investment decisions for the Strategy, but there is no guarantee that its techniques will produce the intended results.&lt;/li&gt;&lt;/ul&gt;As with all investments, you may lose money by investing in the Strategy.</rr:RiskNarrativeTextBlock>

A higher portfolio turnover rate may indicate higher transaction costs and may result in higher taxes when Strategy shares are held in a taxable account. These transaction costs, which are not reflected in the Annual Strategy Operating Expenses or in the Examples, affect the Strategy's performance.

  <rr:StrategyNarrativeTextBlock contextRef="Duration_01Jan2012_31Dec2012S000010276_Member">The Strategy seeks the highest total return over time consistent with its asset mix. Total return includes capital growth and income. To achieve its investment objective, the Strategy invests in a combination of portfolios of The AllianceBernstein Pooling Portfolios representing a variety of asset classes and investment styles (the "Underlying Portfolios"). The Strategy is managed to the specific year of planned retirement included in its name (the "retirement date"). The Strategy's asset mixes will become more conservative each year until reaching the year approximately fifteen years after the retirement date (the "target year") at which time the asset allocation mix will become static. This reflects the objective of pursuing the maximum amount of capital growth, consistent with a reasonable amount of risk, during the investor's pre-retirement and early retirement years. After retirement the Strategy's investment mix anticipates that an investor may take withdrawals from his or her account to provide supplemental retirement income.&lt;br /&gt;&lt;br /&gt;  After the retirement date of the Strategy, its asset mix seeks to minimize the likelihood that an investor in the Strategy experiences a significant loss of capital at a more advanced age. The asset mix for the Strategy will continue to change after the Strategy's retirement date with an increasing exposure to investments in fixed-income securities and short-term bonds until fifteen years after the Strategy's retirement date. Thereafter, the target asset allocation for the Strategy will generally be fixed. The static allocation of the Strategy's asset mix will be 27.5% short-duration bonds, 37.5% other fixed-income securities, 12.5% Volatility Management Portfolio, 15.5% other equities and 7% Multi-Asset Real Return Portfolio.&lt;br /&gt;&lt;br /&gt;  The Underlying Portfolios will include a Portfolio, the Volatility Management Portfolio, that is designed to reduce the overall effect of equity market volatility on the Strategy and the effects of adverse equity market conditions on its performance. The Volatility Management Portfolio will be a component of the Strategy's equity asset allocation. Under normal market conditions, this Underlying Portfolio will invest predominantly in equity securities. If the Adviser determines that the equity markets pose disproportionate risks, the Adviser will reduce (or eliminate) this Underlying Portfolio's equity investments and invest in fixed-income securities or other non-equity asset classes to reduce the risks of the Strategy's investments in equity securities.&lt;br /&gt;&lt;br /&gt;  The Adviser will allow the relative weightings of the Strategy's asset classes to vary in response to the markets, but ordinarily only by plus/minus 5%. Beyond those ranges, the Adviser will generally rebalance the portfolio toward the target asset allocation for the Strategy. However, there may be occasions when those ranges will expand to 10% of the Strategy's portfolio due to, among other things, appreciation of one of the asset classes.&lt;br /&gt;&lt;br /&gt;  The following chart illustrates how the asset mix of the Strategy will vary over time. In general, the asset mix of the Strategy will gradually shift from one comprised largely of Underlying Portfolios that emphasize investments in stocks to one that is comprised of a mixture of Underlying Portfolios that invest in bonds (including short-duration bonds) and stocks.&lt;br /&gt;&lt;br /&gt;

  <rr:RiskHeading contextRef="Duration_01Jan2012_31Dec2012S000010276_Member">PRINCIPAL RISKS</rr:RiskHeading>
  <rr:RiskNarrativeTextBlock contextRef="Duration_01Jan2012_31Dec2012S000010276_Member">The value of your investment in the Strategy will change with changes in the values of the Strategy's investments in the Underlying Portfolios. There is no assurance that the Strategy will provide an investor with adequate income at or through retirement. The degree to which the following risks apply varies according to the Strategy's asset allocation.  &lt;ul type="square"&gt;&lt;li style="margin-left:-20px"&gt;MARKET RISK: The value of the Strategy's investments will fluctuate as the stock or bond market fluctuates. The value of its investments may decline, sometimes rapidly and unpredictably, simply because of economic changes or other events that affect large portions of the market. It includes the risk that a particular style of investing, such as growth or value, may be underperforming the stock market generally.&lt;/li&gt;&lt;/ul&gt;  &lt;ul type="square"&gt;&lt;li style="margin-left:-20px"&gt;INTEREST RATE RISK: Changes in interest rates will affect the value of the Strategy's investments in Underlying Portfolios that invest in fixed-income securities. When interest rates rise, the value of investments in fixed-income securities tends to fall and this decrease in value may not be offset by higher income from new investments. Interest rate risk is generally greater for fixed-income securities with longer maturities or durations. Investments in fixed-income securities with lower credit ratings ("junk bonds") tend to have a higher probability that an issuer will default or fail to meet its payment obligations.&lt;/li&gt;&lt;/ul&gt;  &lt;ul type="square"&gt;&lt;li style="margin-left:-20px"&gt;CREDIT RISK: An issuer or guarantor of a fixed-income security, or the counterparty to a derivatives or other contract, may be unable or unwilling to make timely payments of interest or principal, or to otherwise honor its obligations. The issuer or guarantor may default, causing a loss of the full principal amount of a security. The degree of risk for a particular security may be reflected in its credit rating. There is the possibility that the credit rating of a fixed-income security may be downgraded after purchase, which may adversely affect the value of the security. Investments in fixed-income securities with lower ratings tend to have a higher probability that an issuer will default or fail to meet its payment obligations.&lt;/li&gt;&lt;/ul&gt;  &lt;ul type="square"&gt;&lt;li style="margin-left:-20px"&gt;ALLOCATION RISK: The allocation of investments among the Underlying Portfolios' different investment styles, such as growth or value, equity or debt securities, or U.S. or non-U.S. securities, may have a more significant effect on the Strategy's NAV when one of these investments is performing more poorly than the other.&lt;/li&gt;&lt;/ul&gt;  &lt;ul type="square"&gt;&lt;li style="margin-left:-20px"&gt;INFLATION RISK: This is the risk that the value of assets or income from the Strategy's investments in the Underlying Portfolios will be less in the future as inflation decreases the value of money. As inflation increases, the value of each Underlying Portfolio's assets can decline as can the value of that Underlying Portfolio's distributions.&lt;/li&gt;&lt;/ul&gt;  &lt;ul type="square"&gt;&lt;li style="margin-left:-20px"&gt;FOREIGN (NON-U.S.) RISK: The Strategy's investments in Underlying Portfolios that invest in securities of non-U.S. issuers may experience more rapid and extreme changes in value than investments in securities of U.S. issuers. These securities may fluctuate more widely in price and may be less liquid due to adverse market, economic, political, regulatory or other factors. This risk is greater when the Strategy has a higher asset allocation of Underlying Portfolios that invest in non-U.S. issuers.&lt;/li&gt;&lt;/ul&gt;  &lt;ul type="square"&gt;&lt;li style="margin-left:-20px"&gt;EMERGING MARKET RISK: Investments in emerging market countries may involve more risk than investments in other foreign countries because the markets in emerging market countries are less developed and less liquid as well as subject to increased economic, political, regulatory and other uncertainties.&lt;/li&gt;&lt;/ul&gt;  &lt;ul type="square"&gt;&lt;li style="margin-left:-20px"&gt;CURRENCY RISK: Fluctuations in currency exchange rates may negatively affect the value of the Strategy's investments or reduce its returns.&lt;/li&gt;&lt;/ul&gt;  &lt;ul type="square"&gt;&lt;li style="margin-left:-20px"&gt;CAPITALIZATION RISK: Investments in small- and mid-capitalization companies by Underlying Portfolios tend to be more volatile than investments in large-capitalization companies. Investments in small-capitalization companies may have additional risks because these companies often have limited product lines, markets, or financial resources.&lt;/li&gt;&lt;/ul&gt;  &lt;ul type="square"&gt;&lt;li style="margin-left:-20px"&gt;FOCUSED PORTFOLIO RISK: The Underlying Portfolios that invest 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.&lt;/li&gt;&lt;/ul&gt;  &lt;ul type="square"&gt;&lt;li style="margin-left:-20px"&gt;DERIVATIVES RISK: Investments in derivatives may be illiquid, difficult to price, and leveraged so that small changes may produce disproportionate losses, and may be subject to counterparty risk to a greater degree than more traditional investments.&lt;/li&gt;&lt;/ul&gt;  &lt;ul type="square"&gt;&lt;li style="margin-left:-20px"&gt;LEVERAGE RISK: Borrowing money or other leverage may make an Underlying Portfolio's investments more volatile because leverage tends to exaggerate the effect of any increase or decrease in the value of its investments. An Underlying Portfolio may create leverage through the use of certain portfolio management techniques such as reverse repurchase agreements or forward commitments, or by borrowing money.&lt;/li&gt;&lt;/ul&gt;  &lt;ul type="square"&gt;&lt;li style="margin-left:-20px"&gt;MANAGEMENT RISK: The Strategy is subject to management risk because it is an actively managed investment fund. The Adviser will apply its investment techniques and risk analyses in making investment decisions for the Strategy, but there is no guarantee that its techniques will produce the intended results.&lt;/li&gt;&lt;/ul&gt;  As with all investments, you may lose money by investing in the Strategy.</rr:RiskNarrativeTextBlock>

  <rr:PortfolioTurnoverTextBlock contextRef="Duration_01Jan2012_31Dec2012S000017765_Member">The Strategy (or an Underlying Portfolio) pays transaction costs, such as commissions, when it buys or sells securities (or "turns over" its portfolio). A higher portfolio turnover rate may indicate higher transaction costs and may result in higher taxes when Strategy shares are held in a taxable account. These transaction costs, which are not reflected in the Annual Strategy Operating Expenses or in the Examples, affect the Strategy's performance. During the most recent fiscal year, the Strategy's portfolio turnover rate (which reflects only purchases and sales of the Underlying Portfolios) was 57% of the average value of its portfolio.</rr:PortfolioTurnoverTextBlock>
  <rr:StrategyHeading contextRef="Duration_01Jan2012_31Dec2012S000017765_Member">PRINCIPAL STRATEGIES:</rr:StrategyHeading>
  <rr:StrategyNarrativeTextBlock contextRef="Duration_01Jan2012_31Dec2012S000017765_Member">The Strategy seeks the highest total return over time consistent with its asset mix. Total return includes capital growth and income. To achieve its investment objective, the Strategy invests in a combination of portfolios of The AllianceBernstein Pooling Portfolios representing a variety of asset classes and investment styles (the "Underlying Portfolios"). The Strategy is managed to the specific year of planned retirement included in its name (the "retirement date"). The Strategy's asset mixes will become more conservative each year until reaching the year approximately fifteen years after the retirement date (the "target year") at which time the asset allocation mix will become static. This reflects the objective of pursuing the maximum amount of capital growth, consistent with a reasonable amount of risk, during the investor's pre-retirement and early retirement years. After retirement the Strategy's investment mix anticipates that an investor may take withdrawals from his or her account to provide supplemental retirement income.&lt;br/&gt;&lt;br/&gt; After the retirement date of the Strategy, its asset mix seeks to minimize the likelihood that an investor in the Strategy experiences a significant loss of capital at a more advanced age. The asset mix for the Strategy will continue to change after the Strategy's retirement date with an increasing exposure to investments in fixed-income securities and short-term bonds until fifteen years after the Strategy's retirement date. Thereafter, the target asset allocation for the Strategy will generally be fixed. The static allocation of the Strategy's asset mix will be 27.5% short-duration bonds, 37.5% other fixed-income securities, 12.5% Volatility Management Portfolio, 15.5% other equities and 7% Multi-Asset Real Return Portfolio.&lt;br/&gt;&lt;br/&gt; The Underlying Portfolios will include a Portfolio, the Volatility Management Portfolio, that is designed to reduce the overall effect of equity market volatility on the Strategy and the effects of adverse equity market conditions on its performance. The Volatility Management Portfolio will be a component of the Strategy's equity asset allocation. Under normal market conditions, this Underlying Portfolio will invest predominantly in equity securities. If the Adviser determines that the equity markets pose disproportionate risks, the Adviser will reduce (or eliminate) this Underlying Portfolio's equity investments and invest in fixed-income securities or other non-equity asset classes to reduce the risks of the Strategy's investments in equity securities.&lt;br/&gt;&lt;br/&gt; The Adviser will allow the relative weightings of the Strategy's asset classes to vary in response to the markets, but ordinarily only by plus/minus 5%. Beyond those ranges, the Adviser will generally rebalance the portfolio toward the target asset allocation for the Strategy. However, there may be occasions when those ranges will expand to 10% of the Strategy's portfolio due to, among other things, appreciation of one of the asset classes.&lt;br/&gt;&lt;br/&gt;The following chart illustrates how the asset mix of the Strategy will vary over time. In general, the asset mix of the Strategy will gradually shift from one comprised largely of Underlying Portfolios that emphasize investments in stocks to one that is comprised of a mixture of Underlying Portfolios that invest in bonds (including short-duration bonds) and stocks.&lt;br/&gt;&lt;br/&gt;

  <rr:RiskNarrativeTextBlock contextRef="Duration_01Jan2012_31Dec2012S000017765_Member">The value of your investment in the Strategy will change with changes in the values of the Strategy's investments in the Underlying Portfolios. There is no assurance that the Strategy will provide an investor with adequate income at or through retirement. The degree to which the following risks apply varies according to the Strategy's asset allocation.&lt;ul type="square"&gt;&lt;li style="margin-left:-20px"&gt; MARKET RISK: The value of the Strategy's investments will fluctuate as the stock or bond market fluctuates. The value of its investments may decline, sometimes rapidly and unpredictably, simply because of economic changes or other events that affect large portions of the market. It includes the risk that a particular style of investing, such as growth or value, may be underperforming the stock market generally.&lt;/li&gt;&lt;/ul&gt;&lt;ul type="square"&gt;&lt;li style="margin-left:-20px"&gt; INTEREST RATE RISK: Changes in interest rates will affect the value of the Strategy's investments in Underlying Portfolios that invest in fixed-income securities. When interest rates rise, the value of investments in fixed-income securities tends to fall and this decrease in value may not be offset by higher income from new investments. Interest rate risk is generally greater for fixed-income securities with longer maturities or durations. Investments in fixed-income securities with lower credit ratings ("junk bonds") tend to have a higher probability that an issuer will default or fail to meet its payment obligations.&lt;/li&gt;&lt;/ul&gt;&lt;ul type="square"&gt;&lt;li style="margin-left:-20px"&gt; CREDIT RISK: An issuer or guarantor of a fixed-income security, or the counterparty to a derivatives or other contract, may be unable or unwilling to make timely payments of interest or principal, or to otherwise honor its obligations. The issuer or guarantor may default, causing a loss of the full principal amount of a security. The degree of risk for a particular security may be reflected in its credit rating. There is the possibility that the credit rating of a fixed-income security may be downgraded after purchase, which may adversely affect the value of the security. Investments in fixed-income securities with lower ratings tend to have a higher probability that an issuer will default or fail to meet its payment obligations.&lt;/li&gt;&lt;/ul&gt;&lt;ul type="square"&gt;&lt;li style="margin-left:-20px"&gt; ALLOCATION RISK: The allocation of investments among the Underlying Portfolios' different investment styles, such as growth or value, equity or debt securities, or U.S. or non-U.S. securities, may have a more significant effect on the Strategy's NAV when one of these investments is performing more poorly than the other.&lt;/li&gt;&lt;/ul&gt;&lt;ul type="square"&gt;&lt;li style="margin-left:-20px"&gt; INFLATION RISK: This is the risk that the value of assets or income from the Strategy's investments in the Underlying Portfolios will be less in the future as inflation decreases the value of money. As inflation increases, the value of each Underlying Portfolio's assets can decline as can the value of that Underlying Portfolio's distributions.&lt;/li&gt;&lt;/ul&gt;&lt;ul type="square"&gt;&lt;li style="margin-left:-20px"&gt; FOREIGN (NON-U.S.) RISK: The Strategy's investments in Underlying Portfolios that invest in securities of non-U.S. issuers may experience more rapid and extreme changes in value than investments in securities of U.S. issuers. These securities may fluctuate more widely in price and may be less liquid due to adverse market, economic, political, regulatory or other factors. This risk is greater when the Strategy has a higher asset allocation of Underlying Portfolios that invest in non-U.S. issuers.&lt;/li&gt;&lt;/ul&gt;&lt;ul type="square"&gt;&lt;li style="margin-left:-20px"&gt; EMERGING MARKET RISK: Investments in emerging market countries may involve more risk than investments in other foreign countries because the markets in emerging market countries are less developed and less liquid as well as subject to increased economic, political, regulatory and other uncertainties.&lt;/li&gt;&lt;/ul&gt;&lt;ul type="square"&gt;&lt;li style="margin-left:-20px"&gt; CURRENCY RISK: Fluctuations in currency exchange rates may negatively affect the value of the Strategy's investments or reduce its returns.&lt;/li&gt;&lt;/ul&gt;&lt;ul type="square"&gt;&lt;li style="margin-left:-20px"&gt; CAPITALIZATION RISK: Investments in small- and mid-capitalization companies by Underlying Portfolios tend to be more volatile than investments in large-capitalization companies. Investments in small-capitalization companies may have additional risks because these companies often have limited product lines, markets, or financial resources.&lt;/li&gt;&lt;/ul&gt;&lt;ul type="square"&gt;&lt;li style="margin-left:-20px"&gt; FOCUSED PORTFOLIO RISK: The Underlying Portfolios that invest 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.&lt;/li&gt;&lt;/ul&gt;&lt;ul type="square"&gt;&lt;li style="margin-left:-20px"&gt; DERIVATIVES RISK: Investments in derivatives may be illiquid, difficult to price, and leveraged so that small changes may produce disproportionate losses, and may be subject to counterparty risk to a greater degree than more traditional investments.&lt;/li&gt;&lt;/ul&gt;&lt;ul type="square"&gt;&lt;li style="margin-left:-20px"&gt; LEVERAGE RISK: Borrowing money or other leverage may make an Underlying Portfolio's investments more volatile because leverage tends to exaggerate the effect of any increase or decrease in the value of its investments. An Underlying Portfolio may create leverage through the use of certain portfolio management techniques such as reverse repurchase agreements or forward commitments, or by borrowing money.&lt;/li&gt;&lt;/ul&gt;&lt;ul type="square"&gt;&lt;li style="margin-left:-20px"&gt; MANAGEMENT RISK: The Strategy is subject to management risk because it is an actively managed investment fund. The Adviser will apply its investment techniques and risk analyses in making investment decisions for the Strategy, but there is no guarantee that its techniques will produce the intended results.&lt;/li&gt;&lt;/ul&gt;  As with all investments, you may lose money by investing in the Strategy.</rr:RiskNarrativeTextBlock>

  <rr:StrategyNarrativeTextBlock contextRef="Duration_01Jan2012_31Dec2012S000010281_Member">The Strategy seeks the highest total return over time consistent with its asset mix. Total return includes capital growth and income. To achieve its investment objective, the Strategy invests in a combination of portfolios of The AllianceBernstein Pooling Portfolios representing a variety of asset classes and investment styles (the "Underlying Portfolios"). The Strategy is managed to the specific year of planned retirement included in its name (the "retirement date"). The Strategy's asset mixes will become more conservative each year until reaching the year approximately fifteen years after the retirement date (the "target year") at which time the asset allocation mix will become static. This reflects the objective of pursuing the maximum amount of capital growth, consistent with a reasonable amount of risk, during the investor's pre-retirement and early retirement years. After retirement the Strategy's investment mix anticipates that an investor may take withdrawals from his or her account to provide supplemental retirement income.&lt;br/&gt;&lt;br/&gt; After the retirement date of the Strategy, its asset mix seeks to minimize the likelihood that an investor in the Strategy experiences a significant loss of capital at a more advanced age. The asset mix for the Strategy will continue to change after the Strategy's retirement date with an increasing exposure to investments in fixed-income securities and short-term bonds until fifteen years after the Strategy's retirement date. Thereafter, the target asset allocation for the Strategy will generally be fixed. The static allocation of the Strategy's asset mix will be 27.5% short-duration bonds, 37.5% other fixed-income securities, 12.5% Volatility Management Portfolio, 15.5% other equities and 7% Multi-Asset Real Return Portfolio.&lt;br/&gt;&lt;br/&gt;The Underlying Portfolios will include a Portfolio, the Volatility Management Portfolio, that is designed to reduce the overall effect of equity market volatility on the Strategy and the effects of adverse equity market conditions on its performance. The Volatility Management Portfolio will be a component of the Strategy's equity asset allocation. Under normal market conditions, this Underlying Portfolio will invest predominantly in equity securities. If the Adviser determines that the equity markets pose disproportionate risks, the Adviser will reduce (or eliminate) this Underlying Portfolio's equity investments and invest in fixed-income securities or other non-equity asset classes to reduce the risks of the Strategy's investments in equity securities.&lt;br/&gt;&lt;br/&gt;The Adviser will allow the relative weightings of the Strategy's asset classes to vary in response to the markets, but ordinarily only by plus/minus 5%. Beyond those ranges, the Adviser will generally rebalance the portfolio toward the target asset allocation for the Strategy. However, there may be occasions when those ranges will expand to 10% of the Strategy's portfolio due to, among other things, appreciation of one of the asset classes.&lt;br/&gt;&lt;br/&gt;The following chart illustrates how the asset mix of the Strategy will vary over time. In general, the asset mix of the Strategy will gradually shift from one comprised largely of Underlying Portfolios that emphasize investments in stocks to one that is comprised of a mixture of Underlying Portfolios that invest in bonds (including short-duration bonds) and stocks.&lt;br/&gt;&lt;br/&gt;

  <rr:RiskHeading contextRef="Duration_01Jan2012_31Dec2012S000010281_Member">PRINCIPAL RISKS</rr:RiskHeading>
  <rr:RiskNarrativeTextBlock contextRef="Duration_01Jan2012_31Dec2012S000010281_Member">The value of your investment in the Strategy will change with changes in the values of the Strategy's investments in the Underlying Portfolios. There is no assurance that the Strategy will provide an investor with adequate income at or through retirement. The degree to which the following risks apply varies according to the Strategy's asset allocation.&lt;ul type="square"&gt;&lt;li style="margin-left: -20px"&gt;MARKET RISK: The value of the Strategy's investments will fluctuate as the stock or bond market fluctuates. The value of its investments may decline, sometimes rapidly and unpredictably, simply because of economic changes or other events that affect large portions of the market. It includes the risk that a particular style of investing, such as growth or value, may be underperforming the stock market generally.&lt;/li&gt;&lt;/ul&gt;&lt;ul type="square"&gt;&lt;li style="margin-left: -20px"&gt;INTEREST RATE RISK: Changes in interest rates will affect the value of the Strategy's investments in Underlying Portfolios that invest in fixed-income securities. When interest rates rise, the value of investments in fixed-income securities tends to fall and this decrease in value may not be offset by higher income from new investments. Interest rate risk is generally greater for fixed-income securities with longer maturities or durations. Investments in fixed-income securities with lower credit ratings ("junk bonds") tend to have a higher probability that an issuer will default or fail to meet its payment obligations.&lt;/li&gt;&lt;/ul&gt;&lt;ul type="square"&gt;&lt;li style="margin-left: -20px"&gt;CREDIT RISK: An issuer or guarantor of a fixed-income security, or the counterparty to a derivatives or other contract, may be unable or unwilling to make timely payments of interest or principal, or to otherwise honor its obligations. The issuer or guarantor may default, causing a loss of the full principal amount of a security. The degree of risk for a particular security may be reflected in its credit rating. There is the possibility that the credit rating of a fixed-income security may be downgraded after purchase, which may adversely affect the value of the security. Investments in fixed-income securities with lower ratings tend to have a higher probability that an issuer will default or fail to meet its payment obligations.&lt;/li&gt;&lt;/ul&gt;&lt;ul type="square"&gt;&lt;li style="margin-left: -20px"&gt;ALLOCATION RISK: The allocation of investments among the Underlying Portfolios' different investment styles, such as growth or value, equity or debt securities, or U.S. or non-U.S. securities, may have a more significant effect on the Strategy's NAV when one of these investments is performing more poorly than the other.&lt;/li&gt;&lt;/ul&gt;&lt;ul type="square"&gt;&lt;li style="margin-left: -20px"&gt;INFLATION RISK: This is the risk that the value of assets or income from the Strategy's investments in the Underlying Portfolios will be less in the future as inflation decreases the value of money. As inflation increases, the value of each Underlying Portfolio's assets can decline as can the value of that Underlying Portfolio's distributions.&lt;/li&gt;&lt;/ul&gt;&lt;ul type="square"&gt;&lt;li style="margin-left: -20px"&gt;FOREIGN (NON-U.S.) RISK: The Strategy's investments in Underlying Portfolios that invest in securities of non-U.S. issuers may experience more rapid and extreme changes in value than investments in securities of U.S. issuers. These securities may fluctuate more widely in price and may be less liquid due to adverse market, economic, political, regulatory or other factors. This risk is greater when the Strategy has a higher asset allocation of Underlying Portfolios that invest in non-U.S. issuers.&lt;/li&gt;&lt;/ul&gt;&lt;ul type="square"&gt;&lt;li style="margin-left: -20px"&gt;EMERGING MARKET RISK: Investments in emerging market countries may involve more risk than investments in other foreign countries because the markets in emerging market countries are less developed and less liquid as well as subject to increased economic, political, regulatory and other uncertainties.&lt;/li&gt;&lt;/ul&gt;&lt;ul type="square"&gt;&lt;li style="margin-left: -20px"&gt;CURRENCY RISK: Fluctuations in currency exchange rates may negatively affect the value of the Strategy's investments or reduce its returns.&lt;/li&gt;&lt;/ul&gt;&lt;ul type="square"&gt;&lt;li style="margin-left: -20px"&gt;CAPITALIZATION RISK: Investments in small- and mid-capitalization companies by Underlying Portfolios tend to be more volatile than investments in large-capitalization companies. Investments in small-capitalization companies may have additional risks because these companies often have limited product lines, markets, or financial resources.&lt;/li&gt;&lt;/ul&gt;&lt;ul type="square"&gt;&lt;li style="margin-left: -20px"&gt;FOCUSED PORTFOLIO RISK: The Underlying Portfolios that invest 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.&lt;/li&gt;&lt;/ul&gt;&lt;ul type="square"&gt;&lt;li style="margin-left: -20px"&gt;DERIVATIVES RISK: Investments in derivatives may be illiquid, difficult to price, and leveraged so that small changes may produce disproportionate losses, and may be subject to counterparty risk to a greater degree than more traditional investments.&lt;/li&gt;&lt;/ul&gt;&lt;ul type="square"&gt;&lt;li style="margin-left: -20px"&gt;LEVERAGE RISK: Borrowing money or other leverage may make an Underlying Portfolio's investments more volatile because leverage tends to exaggerate the effect of any increase or decrease in the value of its investments. An Underlying Portfolio may create leverage through the use of certain portfolio management techniques such as reverse repurchase agreements or forward commitments, or by borrowing money.&lt;/li&gt;&lt;/ul&gt;&lt;ul type="square"&gt;&lt;li style="margin-left: -20px"&gt;MANAGEMENT RISK: The Strategy is subject to management risk because it is an actively managed investment fund. The Adviser will apply its investment techniques and risk analyses in making investment decisions for the Strategy, but there is no guarantee that its techniques will produce the intended results.&lt;/li&gt;&lt;/ul&gt; As with all investments, you may lose money by investing in the Strategy.</rr:RiskNarrativeTextBlock>

  <rr:PortfolioTurnoverTextBlock contextRef="Duration_01Jan2012_31Dec2012S000010285_Member">The Strategy (or an Underlying Portfolio) pays transaction costs, such as commissions, when it buys or sells securities (or &amp;#8220turns over&amp;#8221 its portfolio). A higher portfolio turnover rate may indicate higher transaction costs and may result in higher taxes when Strategy shares are held in a taxable account. These transaction costs, which are not reflected in the Annual Strategy Operating Expenses or in the Examples, affect the Strategy&amp;#8217;s performance. During the most recent fiscal year, the Strategy&amp;#8217;s portfolio turnover rate (which reflects only purchases and sales of the Underlying Portfolios) was 25% of the average value of its portfolio.</rr:PortfolioTurnoverTextBlock>

  <rr:StrategyNarrativeTextBlock contextRef="Duration_01Jan2012_31Dec2012S000010285_Member">The Strategy seeks the highest total return over time consistent with its asset mix. Total return includes capital growth and income. To achieve its investment objective, the Strategy invests in a combination of portfolios of The AllianceBernstein Pooling Portfolios representing a variety of asset classes and investment styles (the "Underlying Portfolios"). The Strategy is managed to the specific year of planned retirement included in its name (the "retirement date"). The Strategy's asset mixes will become more conservative each year until reaching the year approximately fifteen years after the retirement date (the "target year") at which time the asset allocation mix will become static. This reflects the objective of pursuing the maximum amount of capital growth, consistent with a reasonable amount of risk, during the investor's pre-retirement and early retirement years. After retirement the Strategy's investment mix anticipates that an investor may take withdrawals from his or her account to provide supplemental retirement income.&lt;br/&gt;&lt;br/&gt; After the retirement date of the Strategy, its asset mix seeks to minimize the likelihood that an investor in the Strategy experiences a significant loss of capital at a more advanced age. The asset mix for the Strategy will continue to change after the Strategy's retirement date with an increasing exposure to investments in fixed-income securities and short-term bonds until fifteen years after the Strategy's retirement date. Thereafter, the target asset allocation for the Strategy will generally be fixed. The static allocation of the Strategy's asset mix will be 27.5% short-duration bonds, 37.5% other fixed-income securities, 12.5% Volatility Management Portfolio, 15.5% other equities and 7% Multi-Asset Real Return Portfolio.&lt;br/&gt;&lt;br/&gt;The Underlying Portfolios will include a Portfolio, the Volatility Management Portfolio, that is designed to reduce the overall effect of equity market volatility on the Strategy and the effects of adverse equity market conditions on its performance. The Volatility Management Portfolio will be a component of the Strategy's equity asset allocation. Under normal market conditions, this Underlying Portfolio will invest predominantly in equity securities. If the Adviser determines that the equity markets pose disproportionate risks, the Adviser will reduce (or eliminate) this Underlying Portfolio's equity investments and invest in fixed-income securities or other non-equity asset classes to reduce the risks of the Strategy's investments in equity securities.&lt;br/&gt;&lt;br/&gt;The Adviser will allow the relative weightings of the Strategy's asset classes to vary in response to the markets, but ordinarily only by plus/minus 5%. Beyond those ranges, the Adviser will generally rebalance the portfolio toward the target asset allocation for the Strategy. However, there may be occasions when those ranges will expand to 10% of the Strategy's portfolio due to, among other things, appreciation of one of the asset classes.&lt;br/&gt;&lt;br/&gt;The following chart illustrates how the asset mix of the Strategy will vary over time. In general, the asset mix of the Strategy will gradually shift from one comprised largely of Underlying Portfolios that emphasize investments in stocks to one that is comprised of a mixture of Underlying Portfolios that invest in bonds (including short-duration bonds) and stocks.&lt;br/&gt;&lt;br/&gt;&lt;div&gt;

  <rr:RiskHeading contextRef="Duration_01Jan2012_31Dec2012S000010285_Member">PRINCIPAL RISKS</rr:RiskHeading>
  <rr:RiskNarrativeTextBlock contextRef="Duration_01Jan2012_31Dec2012S000010285_Member">The value of your investment in the Strategy will change with changes in the values of the Strategy's investments in the Underlying Portfolios. There is no assurance that the Strategy will provide an investor with adequate income at or through retirement. The degree to which the following risks apply varies according to the Strategy's asset allocation.&lt;ul type="square"&gt;&lt;li style="margin-left: -20px"&gt;MARKET RISK: The value of the Strategy's investments will fluctuate as the stock or bond market fluctuates. The value of its investments may decline, sometimes rapidly and unpredictably, simply because of economic changes or other events that affect large portions of the market. It includes the risk that a particular style of investing, such as growth or value, may be underperforming the stock market generally.&lt;/li&gt;&lt;/ul&gt;&lt;ul type="square"&gt;&lt;li style="margin-left: -20px"&gt;INTEREST RATE RISK: Changes in interest rates will affect the value of the Strategy's investments in Underlying Portfolios that invest in fixed-income securities. When interest rates rise, the value of investments in fixed-income securities tends to fall and this decrease in value may not be offset by higher income from new investments. Interest rate risk is generally greater for fixed-income securities with longer maturities or durations. Investments in fixed-income securities with lower credit ratings ("junk bonds") tend to have a higher probability that an issuer will default or fail to meet its payment obligations.&lt;/li&gt;&lt;/ul&gt;&lt;ul type="square"&gt;&lt;li style="margin-left: -20px"&gt;CREDIT RISK: An issuer or guarantor of a fixed-income security, or the counterparty to a derivatives or other contract, may be unable or unwilling to make timely payments of interest or principal, or to otherwise honor its obligations. The issuer or guarantor may default, causing a loss of the full principal amount of a security. The degree of risk for a particular security may be reflected in its credit rating. There is the possibility that the credit rating of a fixed-income security may be downgraded after purchase, which may adversely affect the value of the security. Investments in fixed-income securities with lower ratings tend to have a higher probability that an issuer will default or fail to meet its payment obligations.&lt;/li&gt;&lt;/ul&gt;&lt;ul type="square"&gt;&lt;li style="margin-left: -20px"&gt;ALLOCATION RISK: The allocation of investments among the Underlying Portfolios' different investment styles, such as growth or value, equity or debt securities, or U.S. or non-U.S. securities, may have a more significant effect on the Strategy's NAV when one of these investments is performing more poorly than the other.&lt;/li&gt;&lt;/ul&gt;&lt;ul type="square"&gt;&lt;li style="margin-left: -20px"&gt;INFLATION RISK: This is the risk that the value of assets or income from the Strategy's investments in the Underlying Portfolios will be less in the future as inflation decreases the value of money. As inflation increases, the value of each Underlying Portfolio's assets can decline as can the value of that Underlying Portfolio's distributions.&lt;/li&gt;&lt;/ul&gt;&lt;ul type="square"&gt;&lt;li style="margin-left: -20px"&gt;FOREIGN (NON-U.S.) RISK: The Strategy's investments in Underlying Portfolios that invest in securities of non-U.S. issuers may experience more rapid and extreme changes in value than investments in securities of U.S. issuers. These securities may fluctuate more widely in price and may be less liquid due to adverse market, economic, political, regulatory or other factors. This risk is greater when the Strategy has a higher asset allocation of Underlying Portfolios that invest in non-U.S. issuers.&lt;/li&gt;&lt;/ul&gt;&lt;ul type="square"&gt;&lt;li style="margin-left: -20px"&gt;EMERGING MARKET RISK: Investments in emerging market countries may involve more risk than investments in other foreign countries because the markets in emerging market countries are less developed and less liquid as well as subject to increased economic, political, regulatory and other uncertainties.&lt;/li&gt;&lt;/ul&gt;&lt;ul type="square"&gt;&lt;li style="margin-left: -20px"&gt;CURRENCY RISK: Fluctuations in currency exchange rates may negatively affect the value of the Strategy's investments or reduce its returns.&lt;/li&gt;&lt;/ul&gt;&lt;ul type="square"&gt;&lt;li style="margin-left: -20px"&gt;CAPITALIZATION RISK: Investments in small- and mid-capitalization companies by Underlying Portfolios tend to be more volatile than investments in large-capitalization companies. Investments in small-capitalization companies may have additional risks because these companies often have limited product lines, markets, or financial resources.&lt;/li&gt;&lt;/ul&gt;&lt;ul type="square"&gt;&lt;li style="margin-left: -20px"&gt;FOCUSED PORTFOLIO RISK: The Underlying Portfolios that invest 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.&lt;/li&gt;&lt;/ul&gt;&lt;ul type="square"&gt;&lt;li style="margin-left: -20px"&gt;DERIVATIVES RISK: Investments in derivatives may be illiquid, difficult to price, and leveraged so that small changes may produce disproportionate losses, and may be subject to counterparty risk to a greater degree than more traditional investments.&lt;/li&gt;&lt;/ul&gt;&lt;ul type="square"&gt;&lt;li style="margin-left: -20px"&gt;LEVERAGE RISK: Borrowing money or other leverage may make an Underlying Portfolio's investments more volatile because leverage tends to exaggerate the effect of any increase or decrease in the value of its investments. An Underlying Portfolio may create leverage through the use of certain portfolio management techniques such as reverse repurchase agreements or forward commitments, or by borrowing money.&lt;/li&gt;&lt;/ul&gt;&lt;ul type="square"&gt;&lt;li style="margin-left: -20px"&gt;MANAGEMENT RISK: The Strategy is subject to management risk because it is an actively managed investment fund. The Adviser will apply its investment techniques and risk analyses in making investment decisions for the Strategy, but there is no guarantee that its techniques will produce the intended results.&lt;/li&gt;&lt;/ul&gt; As with all investments, you may lose money by investing in the Strategy.</rr:RiskNarrativeTextBlock>

A higher portfolio turnover rate may indicate higher transaction costs and may result in higher taxes when Strategy shares are held in a taxable account. These transaction costs, which are not reflected in the Annual Strategy Operating Expenses or in the Examples, affect the Strategy's performance.

  <rr:StrategyNarrativeTextBlock contextRef="Duration_01Jan2012_31Dec2012S000017766_Member">The Strategy seeks the highest total return over time consistent with its asset mix. Total return includes capital growth and income. To achieve its investment objective, the Strategy invests in a combination of portfolios of The AllianceBernstein Pooling Portfolios representing a variety of asset classes and investment styles (the "Underlying Portfolios"). The Strategy is managed to the specific year of planned retirement included in its name (the "retirement date"). The Strategy's asset mixes will become more conservative each year until reaching the year approximately fifteen years after the retirement date (the "target year") at which time the asset allocation mix will become static. This reflects the objective of pursuing the maximum amount of capital growth, consistent with a reasonable amount of risk, during the investor's pre-retirement and early retirement years. After retirement the Strategy's investment mix anticipates that an investor may take withdrawals from his or her account to provide supplemental retirement income. &lt;br/&gt;&lt;br/&gt;After the retirement date of the Strategy, its asset mix seeks to minimize the likelihood that an investor in the Strategy experiences a significant loss of capital at a more advanced age. The asset mix for the Strategy will continue to change after the Strategy's retirement date with an increasing exposure to investments in fixed-income securities and short-term bonds until fifteen years after the Strategy's retirement date. Thereafter, the target asset allocation for the Strategy will generally be fixed. The static allocation of the Strategy's asset mix will be 27.5% short-duration bonds, 37.5% other fixed-income securities, 12.5% Volatility Management Portfolio, 15.5% other equities and 7% Multi-Asset Real Return Portfolio. &lt;br/&gt;&lt;br/&gt;The Underlying Portfolios will include a Portfolio, the Volatility Management Portfolio, that is designed to reduce the overall effect of equity market volatility on the Strategy and the effects of adverse equity market conditions on its performance. The Volatility Management Portfolio will be a component of the Strategy's equity asset allocation. Under normal market conditions, this Underlying Portfolio will invest predominantly in equity securities. If the Adviser determines that the equity markets pose disproportionate risks, the Adviser will reduce (or eliminate) this Underlying Portfolio's equity investments and invest in fixed-income securities or other non-equity asset classes to reduce the risks of the Strategy's investments in equity securities. &lt;br/&gt;&lt;br/&gt;The Adviser will allow the relative weightings of the Strategy's asset classes to vary in response to the markets, but ordinarily only by plus/minus 5%. Beyond those ranges, the Adviser will generally rebalance the portfolio toward the target asset allocation for the Strategy. However, there may be occasions when those ranges will expand to 10% of the Strategy's portfolio due to, among other things, appreciation of one of the asset classes.&lt;br/&gt;&lt;br/&gt;The following chart illustrates how the asset mix of the Strategy will vary over time. In general, the asset mix of the Strategy will gradually shift from one comprised largely of Underlying Portfolios that emphasize investments in stocks to one that is comprised of a mixture of Underlying Portfolios that invest in bonds (including short-duration bonds) and stocks. &lt;br/&gt;&lt;br/&gt;&lt;div&gt;

  <rr:RiskHeading contextRef="Duration_01Jan2012_31Dec2012S000017766_Member">PRINCIPAL RISKS</rr:RiskHeading>
  <rr:RiskNarrativeTextBlock contextRef="Duration_01Jan2012_31Dec2012S000017766_Member">The value of your investment in the Strategy will change with changes in the values of the Strategy's investments in the Underlying Portfolios. There is no assurance that the Strategy will provide an investor with adequate income at or through retirement. The degree to which the following risks apply varies according to the Strategy's asset allocation. &lt;ul type="square"&gt;&lt;li style="margin-left: -20px"&gt;MARKET RISK: The value of the Strategy's investments will fluctuate as the stock or bond market fluctuates. The value of its investments may decline, sometimes rapidly and unpredictably, simply because of economic changes or other events that affect large portions of the market. It includes the risk that a particular style of investing, such as growth or value, may be underperforming the stock market generally.&lt;/li&gt;&lt;/ul&gt;&lt;ul type="square"&gt;&lt;li style="margin-left: -20px"&gt;INTEREST RATE RISK: Changes in interest rates will affect the value of the Strategy's investments in Underlying Portfolios that invest in fixed-income securities. When interest rates rise, the value of investments in fixed-income securities tends to fall and this decrease in value may not be offset by higher income from new investments. Interest rate risk is generally greater for fixed-income securities with longer maturities or durations. Investments in fixed-income securities with lower credit ratings ("junk bonds") tend to have a higher probability that an issuer will default or fail to meet its payment obligations.&lt;/li&gt;&lt;/ul&gt;&lt;ul type="square"&gt;&lt;li style="margin-left: -20px"&gt;CREDIT RISK: An issuer or guarantor of a fixed-income security, or the counterparty to a derivatives or other contract, may be unable or unwilling to make timely payments of interest or principal, or to otherwise honor its obligations. The issuer or guarantor may default, causing a loss of the full principal amount of a security. The degree of risk for a particular security may be reflected in its credit rating. There is the possibility that the credit rating of a fixed-income security may be downgraded after purchase, which may adversely affect the value of the security. Investments in fixed-income securities with lower ratings tend to have a higher probability that an issuer will default or fail to meet its payment obligations.&lt;/li&gt;&lt;/ul&gt;&lt;ul type="square"&gt;&lt;li style="margin-left: -20px"&gt;ALLOCATION RISK: The allocation of investments among the Underlying Portfolios' different investment styles, such as growth or value, equity or debt securities, or U.S. or non-U.S. securities, may have a more significant effect on the Strategy's NAV when one of these investments is performing more poorly than the other.&lt;/li&gt;&lt;/ul&gt;&lt;ul type="square"&gt;&lt;li style="margin-left: -20px"&gt;INFLATION RISK: This is the risk that the value of assets or income from the Strategy's investments in the Underlying Portfolios will be less in the future as inflation decreases the value of money. As inflation increases, the value of each Underlying Portfolio's assets can decline as can the value of that Underlying Portfolio's distributions.&lt;/li&gt;&lt;/ul&gt;&lt;ul type="square"&gt;&lt;li style="margin-left: -20px"&gt;FOREIGN (NON-U.S.) RISK: The Strategy's investments in Underlying Portfolios that invest in securities of non-U.S. issuers may experience more rapid and extreme changes in value than investments in securities of U.S. issuers. These securities may fluctuate more widely in price and may be less liquid due to adverse market, economic, political, regulatory or other factors. This risk is greater when the Strategy has a higher asset allocation of Underlying Portfolios that invest in non-U.S. issuers.&lt;/li&gt;&lt;/ul&gt;&lt;ul type="square"&gt;&lt;li style="margin-left: -20px"&gt; EMERGING MARKET RISK: Investments in emerging market countries may involve more risk than investments in other foreign countries because the markets in emerging market countries are less developed and less liquid as well as subject to increased economic, political, regulatory and other uncertainties.&lt;/li&gt;&lt;/ul&gt;&lt;ul type="square"&gt;&lt;li style="margin-left: -20px"&gt;CURRENCY RISK: Fluctuations in currency exchange rates may negatively affect the value of the Strategy's investments or reduce its returns.&lt;/li&gt;&lt;/ul&gt;&lt;ul type="square"&gt;&lt;li style="margin-left: -20px"&gt;CAPITALIZATION RISK: Investments in small- and mid-capitalization companies by Underlying Portfolios tend to be more volatile than investments in large-capitalization companies. Investments in small-capitalization companies may have additional risks because these companies often have limited product lines, markets, or financial resources.&lt;/li&gt;&lt;/ul&gt;&lt;ul type="square"&gt;&lt;li style="margin-left: -20px"&gt;FOCUSED PORTFOLIO RISK: The Underlying Portfolios that invest 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.&lt;/li&gt;&lt;/ul&gt;&lt;ul type="square"&gt;&lt;li style="margin-left: -20px"&gt;DERIVATIVES RISK: Investments in derivatives may be illiquid, difficult to price, and leveraged so that small changes may produce disproportionate losses, and may be subject to counterparty risk to a greater degree than more traditional investments. &lt;/li&gt;&lt;/ul&gt;&lt;ul type="square"&gt;&lt;li style="margin-left: -20px"&gt;LEVERAGE RISK: Borrowing money or other leverage may make an Underlying Portfolio's investments more volatile because leverage tends to exaggerate the effect of any increase or decrease in the value of its investments. An Underlying Portfolio may create leverage through the use of certain portfolio management techniques such as reverse repurchase agreements or forward commitments, or by borrowing money.&lt;/li&gt;&lt;/ul&gt;&lt;ul type="square"&gt;&lt;li style="margin-left: -20px"&gt;MANAGEMENT RISK: The Strategy is subject to management risk because it is an actively managed investment fund. The Adviser will apply its investment techniques and risk analyses in making investment decisions for the Strategy, but there is no guarantee that its techniques will produce the intended results.&lt;/li&gt;&lt;/ul&gt;As with all investments, you may lose money by investing in the Strategy.</rr:RiskNarrativeTextBlock>

  <rr:StrategyNarrativeTextBlock contextRef="Duration_01Jan2012_31Dec2012S000010279_Member">The Strategy seeks the highest total return over time consistent with its asset mix. Total return includes capital growth and income. To achieve its investment objective, the Strategy invests in a combination of portfolios of The AllianceBernstein Pooling Portfolios representing a variety of asset classes and investment styles (the "Underlying Portfolios"). The Strategy is managed to the specific year of planned retirement included in its name (the "retirement date"). The Strategy's asset mixes will become more conservative each year until reaching the year approximately fifteen years after the retirement date (the "target year") at which time the asset allocation mix will become static. This reflects the objective of pursuing the maximum amount of capital growth, consistent with a reasonable amount of risk, during the investor's pre-retirement and early retirement years. After retirement the Strategy's investment mix anticipates that an investor may take withdrawals from his or her account to provide supplemental retirement income.&lt;br/&gt;&lt;br/&gt;After the retirement date of the Strategy, its asset mix seeks to minimize the likelihood that an investor in the Strategy experiences a significant loss of capital at a more advanced age. The asset mix for the Strategy will continue to change after the Strategy's retirement date with an increasing exposure to investments in fixed-income securities and short-term bonds until fifteen years after the Strategy's retirement date. Thereafter, the target asset allocation for the Strategy will generally be fixed. The static allocation of the Strategy's asset mix will be 27.5% short-duration bonds, 37.5% other fixed-income securities, 12.5% Volatility Management Portfolio, 15.5% other equities and 7% Multi-Asset Real Return Portfolio.&lt;br/&gt;&lt;br/&gt;The Underlying Portfolios will include a Portfolio, the Volatility Management Portfolio, that is designed to reduce the overall effect of equity market volatility on the Strategy and the effects of adverse equity market conditions on its performance. The Volatility Management Portfolio will be a component of the Strategy's equity asset allocation. Under normal market conditions, this Underlying Portfolio will invest predominantly in equity securities. If the Adviser determines that the equity markets pose disproportionate risks, the Adviser will reduce (or eliminate) this Underlying Portfolio's equity investments and invest in fixed-income securities or other non-equity asset classes to reduce the risks of the Strategy's investments in equity securities.&lt;br/&gt;&lt;br/&gt;The Adviser will allow the relative weightings of the Strategy's asset classes to vary in response to the markets, but ordinarily only by plus/minus 5%. Beyond those ranges, the Adviser will generally rebalance the portfolio toward the target asset allocation for the Strategy. However, there may be occasions when those ranges will expand to 10% of the Strategy's portfolio due to, among other things, appreciation of one of the asset classes.&lt;br/&gt;&lt;br/&gt; The following chart illustrates how the asset mix of the Strategy will vary over time. In general, the asset mix of the Strategy will gradually shift from one comprised largely of Underlying Portfolios that emphasize investments in stocks to one that is comprised of a mixture of Underlying Portfolios that invest in bonds (including short-duration bonds) and stocks.&lt;br/&gt;&lt;br/&gt;
