  <rr:StrategyNarrativeTextBlock contextRef="Duration_29Sep2011_28Sep2012S000016521_Member">&lt;font style="FONT-FAMILY: Times New Roman" size="2"&gt;As its primary strategy, the Fund will invest at least 90% of its assets in the component securities (the "Component Securities") of the Underlying Index, depositary receipts representing Component Securities and investments that have economic characteristics that are substantially identical to the economic characteristics of the Component Securities of the Underlying Index. Such securities may include domestic and international equity securities (including common stocks and real estate investment trusts) and fixed income securities (including bonds, treasury bills and notes, mortgage real estate investment trusts, cash, cash equivalents and short-term money market instruments). The domestic equity portion may include securities from all capitalization ranges. Only investment-grade fixed income securities are eligible for inclusion in the fixed income portion of the Underlying Index. The Fund employs a representative sampling indexing strategy in managing the portfolio by holding equity securities and fixed income securities that, in the aggregate, are intended to approximate the Underlying Index in terms of key characteristics, such as price/earnings ratio, earnings growth, maturity, duration, or dividend yield. The Fund will provide shareholders with at least 60 days' notice of any change in these policies. &lt;/font&gt;&lt;br/&gt;&lt;br/&gt;&lt;font style="FONT-FAMILY: Times New Roman" size="2"&gt;The Underlying Index is comprised of securities from three broad asset classes: international equities, domestic equities, and fixed income, and is designed to represent a diversified portfolio of securities with the potential to outperform the Lipper Mixed-Asset Target 2010 Index, on a risk adjusted basis. The current allocation of the Underlying Index is approximately 3% in international equities, 10% in domestic equities and 87% in fixed income and will be systematically reconstituted and rebalanced annually, or quarterly when necessary, pursuant to a proprietary methodology developed by Zacks Investment Research ("Zacks"), the creator of the Underlying Index. Prior to the target termination date of December 31, 2010, the weighted average duration for the fixed income securities was, collectively, aimed to match the time to such date. Following the target date, the duration for the fixed income securities increases each year up to a maximum duration of five years. As of the target date, the Underlying Index had approximately a 10% allocation to equity securities. Over the five years following the target date, allocations shift from conservative to more moderately-conservative allocations, allowing for a larger exposure to equities than at the target date ("Moderately-Conservative Allocation"). The securities in the universe are selected using a proprietary methodology developed by Zacks. Investors should note that the allocations listed above, and in the chart below, are as of June 30, 2012. &lt;/font&gt;&lt;br/&gt;&lt;br/&gt;&lt;font style="FONT-FAMILY: Times New Roman" size="2"&gt;The following chart shows how the investment glidepath for the Fund is expected to gradually shift to a Moderately-Conservative Allocation. The actual asset allocations of the Fund may differ from this chart. The Fund seeks to achieve its final target allocation five years following the target date. &lt;/font&gt;&lt;br/&gt;&lt;center&gt;&lt;img alt="chart" src="g380757g380757g27v59.jpg"&gt;&lt;/img&gt;&lt;/center&gt;</rr:StrategyNarrativeTextBlock>
  <rr:RiskNarrativeTextBlock contextRef="Duration_29Sep2011_28Sep2012S000016521_Member">&lt;font style="FONT-FAMILY: Times New Roman" size="2"&gt;The following summarizes the principal risks that have been identified for the Fund. &lt;/font&gt;&lt;ul type="square"&gt;&lt;li style="margin-left:-20px"&gt;&lt;blockquote&gt;&lt;font style="FONT-FAMILY: Times New Roman" size="2"&gt;The Fund is subject to &lt;i&gt;stock market risk&lt;/i&gt;, which is the risk that stock prices overall will decline over a given period of time. The Fund&amp;#8217;s total return, like stock prices generally, will fluctuate within a wide range, so an investor could lose money over short or even long periods. Stock markets tend to be volatile, with periods of rising prices and periods of falling prices. The stock market has been subject to significant volatility recently which has increased the risks associated with an investment in the Fund. &lt;/font&gt;&lt;/blockquote&gt;&lt;/li&gt;&lt;/ul&gt;&lt;ul type="square"&gt;&lt;li style="margin-left:-20px"&gt;&lt;blockquote&gt;&lt;font style="FONT-FAMILY: Times New Roman" size="2"&gt;The Fund is subject to &lt;i&gt;index risk&lt;/i&gt;, which is the risk that securities in the Underlying Index may under-perform fixed income investments or stock market investments that track other markets, segments or sectors. The Advisor does not actively manage the Fund and therefore does not attempt to analyze, quantify or control the risks associated with investing in securities included in, or representative of, the Underlying Index. &lt;/font&gt;&lt;/blockquote&gt;&lt;/li&gt;&lt;/ul&gt;&lt;ul type="square"&gt;&lt;li style="margin-left:-20px"&gt;&lt;blockquote&gt;&lt;font style="FONT-FAMILY: Times New Roman" size="2"&gt;The Fund is subject to &lt;i&gt;large-capitalization risk&lt;/i&gt;, which is the risk that large-capitalization companies may grow slower than the overall economy and tend to go in and out of favor based on market and economic conditions. &lt;/font&gt;&lt;/blockquote&gt;&lt;/li&gt;&lt;/ul&gt;&lt;ul type="square"&gt;&lt;li style="margin-left:-20px"&gt;&lt;blockquote&gt;&lt;font style="FONT-FAMILY: Times New Roman" size="2"&gt;The Fund is subject to &lt;i&gt;small- and mid-capitalization risk&lt;/i&gt;, which is the risk that returns from small- and mid-capitalization stocks may trail returns from the overall stock market. Historically, these stocks have been more volatile in price than the large-capitalization stocks. &lt;/font&gt;&lt;/blockquote&gt;&lt;/li&gt;&lt;/ul&gt;&lt;ul type="square"&gt;&lt;li style="margin-left:-20px"&gt;&lt;blockquote&gt;&lt;font style="FONT-FAMILY: Times New Roman" size="2"&gt;The Fund is subject to &lt;i&gt;non-correlation risk&lt;/i&gt;, which is the risk that the securities held by the Fund will not provide investment performance tracking the Underlying Index. &lt;/font&gt;&lt;/blockquote&gt;&lt;/li&gt;&lt;/ul&gt;&lt;ul type="square"&gt;&lt;li style="margin-left:-20px"&gt;&lt;blockquote&gt;&lt;font style="FONT-FAMILY: Times New Roman" size="2"&gt;The Fund is subject to &lt;i&gt;market price risk&lt;/i&gt;, which is the risk associated with the fact that the db-X Target Date Shares are listed on NYSE Arca and can be bought and sold in the secondary market at market prices. Although it is expected that the market price of the db-X Target Date Shares typically will approximate its NAV, there may be times when the market price and the NAV differ significantly. Thus, you may pay more than NAV when buying db-X Target Date Shares on the secondary market, and you may receive less than NAV when you sell db-X Target Date Shares. &lt;/font&gt;&lt;/blockquote&gt;&lt;/li&gt;&lt;/ul&gt;&lt;ul type="square"&gt;&lt;li style="margin-left:-20px"&gt;&lt;blockquote&gt;&lt;font style="FONT-FAMILY: Times New Roman" size="2"&gt;The Fund is subject to &lt;i&gt;foreign securities risk&lt;/i&gt;, which is the risk that political and economic events unique to a foreign country or region will affect those markets and their issuers. These events will not necessarily affect the U.S. economy or similar issuers located in the United States. In addition, investments in foreign countries are generally denominated in a foreign currency. As a result, changes in the value of those currencies compared to the U.S. dollar may affect (positively or negatively) the value of a Fund&amp;#8217;s investments. These currency movements may happen separately from and in response to events that do not otherwise affect the value of the security in the issuer&amp;#8217;s home country. &lt;/font&gt;&lt;/blockquote&gt;&lt;/li&gt;&lt;/ul&gt;&lt;ul type="square"&gt;&lt;li style="margin-left:-20px"&gt;&lt;blockquote&gt;&lt;font style="FONT-FAMILY: Times New Roman" size="2"&gt;The Fund is subject to &lt;i&gt;secondary market risk&lt;/i&gt;. Although the db-X Target Date Shares are listed for trading on NYSE Arca, it is possible that an active trading market may not be maintained. Trading of the db-X Target Date Shares on NYSE Arca may be halted if NYSE Arca officials deem such action appropriate, if the db-X Target Date Shares are delisted from NYSE Arca or if the activation of market-wide &amp;#8220;circuit breakers&amp;#8221; halts stock trading generally. &lt;/font&gt;&lt;/blockquote&gt;&lt;/li&gt;&lt;/ul&gt;&lt;ul type="square"&gt;&lt;li style="margin-left:-20px"&gt;&lt;blockquote&gt;&lt;font style="FONT-FAMILY: Times New Roman" size="2"&gt;The Fund is subject to&lt;i&gt; REIT risk&lt;/i&gt;. The Fund&amp;#8217;s investments in the securities of REITs may subject the Fund to the risks associated with the direct ownership of real estate. Also, when investing in REITs, in addition to the advisory fees and other expenses the Fund bears directly in connection with its own operations, the Fund will also bear its pro rata portion of the REITs management fees and other expenses. As such, the Fund&amp;#8217;s shareholders would indirectly bear the expenses of the Fund and the REITs, some or all of which would be duplicative. &lt;/font&gt;&lt;/blockquote&gt;&lt;/li&gt;&lt;/ul&gt;&lt;ul type="square"&gt;&lt;li style="margin-left:-20px"&gt;&lt;blockquote&gt;&lt;font style="FONT-FAMILY: Times New Roman" size="2"&gt;The Fund is subject to &lt;i&gt;fixed income risk&lt;/i&gt;. The prices of fixed income securities respond to economic developments, particularly interest rate changes, as well as to perceptions about the credit risk of individual issuers. Increases in interest rates can cause the prices of the Fund&amp;#8217;s fixed income securities to decline, and the level of current income from a portfolio of fixed income securities may decline in certain interest rate environments. &lt;/font&gt;&lt;/blockquote&gt;&lt;/li&gt;&lt;/ul&gt;&lt;ul type="square"&gt;&lt;li style="margin-left:-20px"&gt;&lt;blockquote&gt;&lt;font style="FONT-FAMILY: Times New Roman" size="2"&gt;The Fund is subject to &lt;i&gt;model risk&lt;/i&gt;, which is the risk that the allocation model used to calculate the Underlying Index will not maximize returns and/or minimize risks in accordance with the targeted time horizon for the Underlying Index. The Advisor cannot offer assurance that a particular allocation will be the appropriate allocation in all circumstances for every investor seeking a particular risk profile or time horizon. &lt;/font&gt;&lt;/blockquote&gt;&lt;/li&gt;&lt;/ul&gt;&lt;font style="FONT-FAMILY: Times New Roman" size="2"&gt;&lt;i&gt;The Fund&amp;#8217;s Shares will change in value, and you could lose money by investing in the Fund. The Fund may not achieve its investment objective. An investment in the Fund is not a deposit with a bank and is not insured or guaranteed by the FDIC or any other government agency. &lt;/i&gt;&lt;/font&gt;</rr:RiskNarrativeTextBlock>

Such securities may include domestic and international equity securities (including common stocks and real estate investment trusts) and fixed income securities (including bonds, treasury bills and notes, mortgage real estate investment trusts, cash, cash equivalents and short-term money market instruments). The domestic equity portion may include securities from all capitalization ranges. Only investment-grade fixed income securities are eligible for inclusion in the fixed income portion of the Underlying Index. The Fund employs a representative sampling indexing strategy in managing the portfolio by holding equity securities and fixed income securities that, in the aggregate, are intended to approximate the Underlying Index in terms of key characteristics, such as price/earnings ratio, earnings growth, maturity, duration, or dividend yield. The Fund will provide shareholders with at least 60 days' notice of any change in these policies. &lt;/font&gt;&lt;br /&gt;&lt;br /&gt;&lt;font style="FONT-FAMILY: Times New Roman" size="2"&gt;The Underlying Index is comprised of securities from three broad asset classes: international equities, domestic equities, and fixed income, and is designed to represent a diversified portfolio of securities with the potential to outperform the Lipper Mixed-Asset Target 2020 Index, on a risk adjusted basis. The current allocation of the Underlying Index is approximately 13% in international equities, 42% in domestic equities and 45% in fixed income and will be systematically reconstituted and rebalanced annually, or quarterly when necessary, pursuant to a proprietary methodology developed by Zacks Investment Research ("Zacks"), the creator of the Underlying Index. The weighted average duration for the fixed income securities will, collectively, match the time to the target termination date, December 31, 2020. Following the target date, the duration for the fixed income securities will increase each year up to a maximum duration of five years. Upon reaching the target date, the Underlying Index will have approximately a 10% allocation to equity securities. Over the next five years, allocations shift from conservative to more moderately-conservative allocations, allowing for a larger exposure to equities than at the target date ("Moderately-Conservative Allocation"). The securities in the universe are selected using a proprietary methodology developed by Zacks.

The Fund&amp;#8217;s total return, like stock prices generally, will fluctuate within a wide range, so an investor could lose money over short or even long periods. Stock markets tend to be volatile, with periods of rising prices and periods of falling prices.

Although it is expected that the market price of the db-X Target Date Shares typically will approximate its NAV, there may be times when the market price and the NAV differ significantly. Thus, you may pay more than NAV when buying db-X Target Date Shares on the secondary market, and you may receive less than NAV when you sell db-X Target Date Shares.&lt;/font&gt;&lt;/blockquote&gt;&lt;/li&gt;&lt;/ul&gt;&lt;ul type="square"&gt;&lt;li style="margin-left:-20px"&gt;&lt;blockquote&gt;&lt;font style="FONT-FAMILY: Times New Roman" size="2"&gt;The Fund is subject to &lt;i&gt;foreign securities risk&lt;/i&gt;, which is the risk that political and economic events unique to a foreign country or region will affect those markets and their issuers. These events will not necessarily affect the U.S. economy or similar issuers located in the United States. In addition, investments in foreign countries are generally denominated in a foreign currency. As a result, changes in the value of those currencies compared to the U.S. dollar may affect (positively or negatively) the value of a Fund&amp;#8217;s investments.

The Fund&amp;#8217;s investments in the securities of REITs may subject the Fund to the risks associated with the direct ownership of real estate. Also, when investing in REITs, in addition to the advisory fees and other expenses the Fund bears directly in connection with its own operations, the Fund will also bear its pro rata portion of the REITs management fees and other expenses.

Increases in interest rates can cause the prices of the Fund&amp;#8217;s fixed income securities to decline, and the level of current income from a portfolio of fixed income securities may decline in certain interest rate environments.&lt;/font&gt;&lt;/blockquote&gt;&lt;/li&gt;&lt;/ul&gt;&lt;ul type="square"&gt;&lt;li style="margin-left:-20px"&gt;&lt;blockquote&gt;&lt;font style="FONT-FAMILY: Times New Roman" size="2"&gt;The Fund is subject to &lt;i&gt;model risk,&lt;/i&gt; which is the risk that the allocation model used to calculate the Underlying Index will not maximize returns and/or minimize risks in accordance with the targeted time horizon for the Underlying Index.

  <rr:StrategyNarrativeTextBlock contextRef="Duration_29Sep2011_28Sep2012S000016524_Member">&lt;font style="FONT-FAMILY: Times New Roman" size="2"&gt;As its primary strategy, the Fund will invest at least 90% of its assets in the component securities (the "Component Securities") of the Underlying Index, depositary receipts representing Component Securities and investments that have economic characteristics that are substantially identical to the economic characteristics of the Component Securities of the Underlying Index. Such securities may include domestic and international equity securities (including common stocks and real estate investment trusts) and fixed income securities (including bonds, treasury bills and notes, mortgage real estate investment trusts, cash, cash equivalents and short-term money market instruments). The domestic equity portion may include securities from all capitalization ranges. Only investment-grade fixed income securities are eligible for inclusion in the fixed income portion of the Underlying Index. The Fund employs a representative sampling indexing strategy in managing the portfolio by holding equity securities and fixed income securities that, in the aggregate, are intended to approximate the Underlying Index in terms of key characteristics, such as price/earnings ratio, earnings growth, maturity, duration, or dividend yield. The Fund will provide shareholders with at least 60 days' notice of any change in these policies. &lt;/font&gt;&lt;br /&gt;&lt;br /&gt; &lt;font style="FONT-FAMILY: Times New Roman" size="2"&gt;The Underlying Index is comprised of securities from three broad asset classes: international equities, domestic equities, and fixed income, and is designed to represent a diversified portfolio of securities with the potential to outperform the Lipper Mixed-Asset Target 2030+ Index, on a risk adjusted basis. The current allocation of the Underlying Index is approximately 21% in international equities, 72% in domestic equities and 7% in fixed income and will be systematically reconstituted and rebalanced annually, or quarterly when necessary, pursuant to a proprietary methodology developed by Zacks Investment Research ("Zacks"), the creator of the Underlying Index. The weighted average duration for the fixed income securities will, collectively, approximate as nearly as possible the time to the target termination date, December 31, 2040. Following the target date, the duration for the fixed income securities will increase each year up to a maximum duration of five years. Upon reaching the target date, the Underlying Index will have approximately a 10% allocation to equity securities. Over the next five years, allocations shift from conservative to more moderately-conservative allocations, allowing for a larger exposure to equities than at the target date ("Moderately-Conservative Allocation"). The securities in the universe are selected using a proprietary methodology developed by Zacks. Investors should note that the allocations listed above, and in the chart below, are as of June 30, 2012. &lt;/font&gt;&lt;br /&gt;&lt;br /&gt; &lt;font style="FONT-FAMILY: Times New Roman" size="2"&gt;The following chart shows how the investment glidepath for the Fund is expected to gradually shift to a Moderately-Conservative Allocation.

The Fund&amp;#8217;s total return, like stock prices generally, will fluctuate within a wide range, so an investor could lose money over short or even long periods. Stock markets tend to be volatile, with periods of rising prices and periods of falling prices. The stock market has been subject to significant volatility recently which has increased the risks associated with an investment in the Fund. &lt;/font&gt;&lt;/blockquote&gt;&lt;/li&gt;&lt;/ul&gt;&lt;ul type="square"&gt;&lt;li style="margin-left:-20px"&gt;&lt;blockquote&gt;&lt;font style="FONT-FAMILY: Times New Roman" size="2"&gt;The Fund is subject to &lt;i&gt;index risk&lt;/i&gt;, which is the risk that securities in the Underlying Index may under-perform fixed income investments or stock market investments that track other markets, segments or sectors. The Advisor does not actively manage the Fund and therefore does not attempt to analyze, quantify or control the risks associated with investing in securities included in, or representative of, the Underlying Index. &lt;/font&gt;&lt;/blockquote&gt;&lt;/li&gt;&lt;/ul&gt;&lt;ul type="square"&gt;&lt;li style="margin-left:-20px"&gt;&lt;blockquote&gt;&lt;font style="FONT-FAMILY: Times New Roman" size="2"&gt;The Fund is subject to &lt;i&gt;large-capitalization risk&lt;/i&gt;, which is the risk that large-capitalization companies may grow slower than the overall economy and tend to go in and out of favor based on market and economic conditions. &lt;/font&gt;&lt;/blockquote&gt;&lt;/li&gt;&lt;/ul&gt;&lt;ul type="square"&gt;&lt;li style="margin-left:-20px"&gt;&lt;blockquote&gt;&lt;font style="FONT-FAMILY: Times New Roman" size="2"&gt;The Fund is subject to &lt;i&gt;small- and mid-capitalization risk&lt;/i&gt;, which is the risk that returns from small- and mid-capitalization stocks may trail returns from the overall stock market. Historically, these stocks have been more volatile in price than the large-capitalization stocks. &lt;/font&gt;&lt;/blockquote&gt;&lt;/li&gt;&lt;/ul&gt;&lt;ul type="square"&gt;&lt;li style="margin-left:-20px"&gt;&lt;blockquote&gt;&lt;font style="FONT-FAMILY: Times New Roman" size="2"&gt;The Fund is subject to &lt;i&gt;non-correlation risk&lt;/i&gt;, which is the risk that the securities held by the Fund will not provide investment performance tracking the Underlying Index. &lt;/font&gt;&lt;/blockquote&gt;&lt;/li&gt;&lt;/ul&gt;&lt;ul type="square"&gt;&lt;li style="margin-left:-20px"&gt;&lt;blockquote&gt;&lt;font style="FONT-FAMILY: Times New Roman" size="2"&gt;The Fund is subject to &lt;i&gt;market price risk&lt;/i&gt;, which is the risk associated with the fact that the db-X Target Date Shares are listed on NYSE Arca and can be bought and sold in the secondary market at market prices. Although it is expected that the market price of the db-X Target Date Shares typically will approximate its NAV, there may be times when the market price and the NAV differ significantly. Thus, you may pay more than NAV when buying db-X Target Date Shares on the secondary market, and you may receive less than NAV when you sell db-X Target Date Shares. &lt;/font&gt;&lt;/blockquote&gt;&lt;/li&gt;&lt;/ul&gt;&lt;ul type="square"&gt;&lt;li style="margin-left:-20px"&gt;&lt;blockquote&gt;&lt;font style="FONT-FAMILY: Times New Roman" size="2"&gt;The Fund is subject to &lt;i&gt;foreign securities risk&lt;/i&gt;, which is the risk that political and economic events unique to a foreign country or region will affect those markets and their issuers. These events will not necessarily affect the U.S. economy or similar issuers located in the United States. In addition, investments in foreign countries are generally denominated in a foreign currency. As a result, changes in the value of those currencies compared to the U.S. dollar may affect (positively or negatively) the value of a Fund&amp;#8217;s investments. These currency movements may happen separately from and in response to events that do not otherwise affect the value of the security in the issuer&amp;#8217;s home country. &lt;/font&gt;&lt;/blockquote&gt;&lt;/li&gt;&lt;/ul&gt;&lt;ul type="square"&gt;&lt;li style="margin-left:-20px"&gt;&lt;blockquote&gt;&lt;font style="FONT-FAMILY: Times New Roman" size="2"&gt;The Fund is subject to &lt;i&gt;secondary market risk&lt;/i&gt;. Although the db-X Target Date Shares are listed for trading on NYSE Arca, it is possible that an active trading market may not be maintained. Trading of the db-X Target Date Shares on NYSE Arca may be halted if NYSE Arca officials deem such action appropriate, if the db-X Target Date Shares are delisted from NYSE Arca or if the activation of market-wide &amp;#8220;circuit breakers&amp;#8221; halts stock trading generally. &lt;/font&gt;&lt;/blockquote&gt;&lt;/li&gt;&lt;/ul&gt;&lt;ul type="square"&gt;&lt;li style="margin-left:-20px"&gt;&lt;blockquote&gt;&lt;font style="FONT-FAMILY: Times New Roman" size="2"&gt;The Fund is subject to&lt;i&gt; REIT risk&lt;/i&gt;. The Fund&amp;#8217;s investments in the securities of REITs may subject the Fund to the risks associated with the direct ownership of real estate. Also, when investing in REITs, in addition to the advisory fees and other expenses the Fund bears directly in connection with its own operations, the Fund will also bear its pro rata portion of the REITs management fees and other expenses. As such, the Fund&amp;#8217;s shareholders would indirectly bear the expenses of the Fund and the REITs, some or all of which would be duplicative. &lt;/font&gt;&lt;/blockquote&gt;&lt;/li&gt;&lt;/ul&gt;&lt;ul type="square"&gt;&lt;li style="margin-left:-20px"&gt;&lt;blockquote&gt;&lt;font style="FONT-FAMILY: Times New Roman" size="2"&gt;The Fund is subject to &lt;i&gt;fixed income risk&lt;/i&gt;. The prices of fixed income securities respond to economic developments, particularly interest rate changes, as well as to perceptions about the credit risk of individual issuers. Increases in interest rates can cause the prices of the Fund&amp;#8217;s fixed income securities to decline, and the level of current income from a portfolio of fixed income securities may decline in certain interest rate environments. &lt;/font&gt;&lt;/blockquote&gt;&lt;/li&gt;&lt;/ul&gt;&lt;ul type="square"&gt;&lt;li style="margin-left:-20px"&gt;&lt;blockquote&gt;&lt;font style="FONT-FAMILY: Times New Roman" size="2"&gt;The Fund is subject to &lt;i&gt;model risk&lt;/i&gt;, which is the risk that the allocation model used to calculate the Underlying Index will not maximize returns and/or minimize risks in accordance with the targeted time horizon for the Underlying Index. The Advisor cannot offer assurance that a particular allocation will be the appropriate allocation in all circumstances for every investor seeking a particular risk profile or time horizon. &lt;/font&gt;&lt;/blockquote&gt;&lt;/li&gt;&lt;/ul&gt;&lt;font style="FONT-FAMILY: Times New Roman" size="2"&gt;&lt;i&gt;The Fund&amp;#8217;s Shares will change in value, and you could lose money by investing in the Fund.

  <rr:RiskNarrativeTextBlock contextRef="Duration_29Sep2011_28Sep2012S000016524_Member">&lt;font style="FONT-FAMILY: Times New Roman" size="2"&gt;The following summarizes the principal risks that have been identified for the Fund. &lt;/font&gt;   &lt;ul type="square"&gt;&lt;li style="margin-left:-20px"&gt;&lt;blockquote&gt;&lt;font style="FONT-FAMILY: Times New Roman" size="2"&gt;The Fund is subject to &lt;i&gt;stock market risk&lt;/i&gt;, which is the risk that stock prices overall will decline over a given period of time. The Fund&amp;#8217;s total return, like stock prices generally, will fluctuate within a wide range, so an investor could lose money over short or even long periods. Stock markets tend to be volatile, with periods of rising prices and periods of falling prices. The stock market has been subject to significant volatility recently which has increased the risks associated with an investment in the Fund. &lt;/font&gt;&lt;/blockquote&gt;&lt;/li&gt;&lt;/ul&gt;&lt;ul type="square"&gt;&lt;li style="margin-left:-20px"&gt;&lt;blockquote&gt;&lt;font style="FONT-FAMILY: Times New Roman" size="2"&gt;The Fund is subject to &lt;i&gt;index risk&lt;/i&gt;, which is the risk that securities in the Underlying Index may under-perform fixed income investments or stock market investments that track other markets, segments or sectors. The Advisor does not actively manage the Fund and therefore does not attempt to analyze, quantify or control the risks associated with investing in securities included in, or representative of, the Underlying Index. &lt;/font&gt;&lt;/blockquote&gt;&lt;/li&gt;&lt;/ul&gt;&lt;ul type="square"&gt;&lt;li style="margin-left:-20px"&gt;&lt;blockquote&gt;&lt;font style="FONT-FAMILY: Times New Roman" size="2"&gt;The Fund is subject to &lt;i&gt;large-capitalization risk&lt;/i&gt;, which is the risk that large-capitalization companies may grow slower than the overall economy and tend to go in and out of favor based on market and economic conditions. &lt;/font&gt;&lt;/blockquote&gt;&lt;/li&gt;&lt;/ul&gt;  &lt;ul type="square"&gt;&lt;li style="margin-left:-20px"&gt;&lt;blockquote&gt;&lt;font style="FONT-FAMILY: Times New Roman" size="2"&gt;The Fund is subject to &lt;i&gt;small- and mid-capitalization risk&lt;/i&gt;, which is the risk that returns from small- and mid-capitalization stocks may trail returns from the overall stock market. Historically, these stocks have been more volatile in price than the large-capitalization stocks. &lt;/font&gt;&lt;/blockquote&gt;&lt;/li&gt;&lt;/ul&gt;   &lt;ul type="square"&gt;&lt;li style="margin-left:-20px"&gt;&lt;blockquote&gt;&lt;font style="FONT-FAMILY: Times New Roman" size="2"&gt;The Fund is subject to &lt;i&gt;non-correlation risk&lt;/i&gt;, which is the risk that the securities held by the Fund will not provide investment performance tracking the Underlying Index. &lt;/font&gt;&lt;/blockquote&gt;&lt;/li&gt;&lt;/ul&gt;&lt;ul type="square"&gt;&lt;li style="margin-left:-20px"&gt;&lt;blockquote&gt;&lt;font style="FONT-FAMILY: Times New Roman" size="2"&gt;The Fund is subject to &lt;i&gt;market price risk&lt;/i&gt;, which is the risk associated with the fact that the db-X Target Date Shares are listed on NYSE Arca and can be bought and sold in the secondary market at market prices. Although it is expected that the market price of the db-X Target Date Shares typically will approximate its NAV, there may be times when the market price and the NAV differ significantly. Thus, you may pay more than NAV when buying db-X Target Date Shares on the secondary market, and you may receive less than NAV when you sell db-X Target Date Shares. &lt;/font&gt;&lt;/blockquote&gt;&lt;/li&gt;&lt;/ul&gt;  &lt;ul type="square"&gt;&lt;li style="margin-left:-20px"&gt;&lt;blockquote&gt;&lt;font style="FONT-FAMILY: Times New Roman" size="2"&gt;The Fund is subject to &lt;i&gt;foreign securities risk&lt;/i&gt;, which is the risk that political and economic events unique to a foreign country or region will affect those markets and their issuers. These events will not necessarily affect the U.S. economy or similar issuers located in the United States. In addition, investments in foreign countries are generally denominated in a foreign currency. As a result, changes in the value of those currencies compared to the U.S. dollar may affect (positively or negatively) the value of a Fund&amp;#8217;s investments. These currency movements may happen separately from and in response to events that do not otherwise affect the value of the security in the issuer&amp;#8217;s home country. &lt;/font&gt;&lt;/blockquote&gt;&lt;/li&gt;&lt;/ul&gt;  &lt;ul type="square"&gt;&lt;li style="margin-left:-20px"&gt;&lt;blockquote&gt;&lt;font style="FONT-FAMILY: Times New Roman" size="2"&gt;The Fund is subject to &lt;i&gt;secondary market risk&lt;/i&gt;. Although the db-X Target Date Shares are listed for trading on NYSE Arca, it is possible that an active trading market may not be maintained. Trading of the db-X Target Date Shares on NYSE Arca may be halted if NYSE Arca officials deem such action appropriate, if the db-X Target Date Shares are delisted from NYSE Arca or if the activation of market-wide &amp;#8220;circuit breakers&amp;#8221; halts stock trading generally. &lt;/font&gt;&lt;/blockquote&gt;&lt;/li&gt;&lt;/ul&gt;  &lt;ul type="square"&gt;&lt;li style="margin-left:-20px"&gt;&lt;blockquote&gt;&lt;font style="FONT-FAMILY: Times New Roman" size="2"&gt;The Fund is subject to&lt;i&gt; REIT risk&lt;/i&gt;. The Fund&amp;#8217;s investments in the securities of REITs may subject the Fund to the risks associated with the direct ownership of real estate. Also, when investing in REITs, in addition to the advisory fees and other expenses the Fund bears directly in connection with its own operations, the Fund will also bear its pro rata portion of the REITs management fees and other expenses. As such, the Fund&amp;#8217;s shareholders would indirectly bear the expenses of the Fund and the REITs, some or all of which would be duplicative. &lt;/font&gt;&lt;/blockquote&gt;&lt;/li&gt;&lt;/ul&gt;  &lt;ul type="square"&gt;&lt;li style="margin-left:-20px"&gt;&lt;blockquote&gt;&lt;font style="FONT-FAMILY: Times New Roman" size="2"&gt;The Fund is subject to &lt;i&gt;fixed income risk&lt;/i&gt;. The prices of fixed income securities respond to economic developments, particularly interest rate changes, as well as to perceptions about the credit risk of individual issuers. Increases in interest rates can cause the prices of the Fund&amp;#8217;s fixed income securities to decline, and the level of current income from a portfolio of fixed income securities may decline in certain interest rate environments. &lt;/font&gt;&lt;/blockquote&gt;&lt;/li&gt;&lt;/ul&gt;&lt;ul type="square"&gt;&lt;li style="margin-left:-20px"&gt;&lt;blockquote&gt;&lt;font style="FONT-FAMILY: Times New Roman" size="2"&gt;The Fund is subject to &lt;i&gt;model risk&lt;/i&gt;, which is the risk that the allocation model used to calculate the Underlying Index will not maximize returns and/or minimize risks in accordance with the targeted time horizon for the Underlying Index. The Advisor cannot offer assurance that a particular allocation will be the appropriate allocation in all circumstances for every investor seeking a particular risk profile or time horizon. &lt;/font&gt;&lt;/blockquote&gt;&lt;/li&gt;&lt;/ul&gt;&lt;font style="FONT-FAMILY: Times New Roman" size="2"&gt;&lt;i&gt;The Fund&amp;#8217;s Shares will change in value, and you could lose money by investing in the Fund. The Fund may not achieve its investment objective. An investment in the Fund is not a deposit with a bank and is not insured or guaranteed by the FDIC or any other government agency. &lt;/i&gt;&lt;/font&gt;</rr:RiskNarrativeTextBlock>
