  <rr:RiskNarrativeTextBlock contextRef="Duration_01Feb2012_31Jan2013S000018974_Member">The fund may not achieve its objective, and it is not intended to be a complete investment program. The value of the fund&amp;#8217;s investments that supports your share value may decrease. If between the time you purchase shares and the time you sell shares the value of the fund&amp;#8217;s investments decreases, you will lose money. Investment values can decrease for a number of reasons. Conditions affecting the overall economy, specific industries or companies in which the fund invests can be worse than expected, and investments may fail to perform as the adviser expects. As a result, the value of your shares may decrease. In addition, you will also be subject to the risks associated with the principal investment strategies of any ETFs in which the fund invests. The principal risks of investing in the fund are: &lt;ul type="square"&gt;&lt;li style="margin-left: 5px"&gt;&lt;blockquote&gt; &lt;b&gt;Correlation to Index Risk.&lt;/b&gt; The risk that the performance of the fund and its index may vary somewhat due to factors such as fund flows, transaction costs, sample selection, and timing differences associated with additions to and deletions from its index.&lt;/blockquote&gt;&lt;/li&gt;&lt;/ul&gt;&lt;ul type="square"&gt;&lt;li style="margin-left: 5px"&gt;&lt;blockquote&gt;&lt;b&gt;Equity Securities Risk.&lt;/b&gt; The risk that events negatively affecting issuers, industries or financial markets in which the fund invests, will impact the value of the stocks held by the fund and thus, the value of the fund&amp;#8217;s shares over short or extended periods.&lt;/blockquote&gt;&lt;/li&gt;&lt;/ul&gt;&lt;ul type="square"&gt;&lt;li style="margin-left: 5px"&gt;&lt;blockquote&gt;&lt;b&gt;Exchange-Traded Funds (ETFs) Risk.&lt;/b&gt; The risk that the value of an ETF will be more volatile than the underlying portfolio of securities the ETF is designed to track, or that the costs to the fund of owning shares of the ETF will exceed those the fund would incur by investing in such securities directly.&lt;/blockquote&gt;&lt;/li&gt;&lt;/ul&gt;&lt;ul type="square"&gt;&lt;li style="margin-left: 5px"&gt;&lt;blockquote&gt;&lt;b&gt;Fund of Funds Risk.&lt;/b&gt; The risk that the underlying funds in which the fund invests will expose the fund to negative performance and additional expenses associated with investment in such funds, and increased volatility.&lt;/blockquote&gt;&lt;/li&gt;&lt;/ul&gt;&lt;ul type="square"&gt;&lt;li style="margin-left: 5px"&gt;&lt;blockquote&gt;&lt;b&gt;Market Volatility Risk.&lt;/b&gt; The risk that the value of the securities in which the fund invests may go up or down in response to the prospects of individual companies and/or general economic conditions. Price changes may be temporary or may last for extended periods.&lt;/blockquote&gt;&lt;/li&gt;&lt;/ul&gt;&lt;ul type="square"&gt;&lt;li style="margin-left: 5px"&gt;&lt;blockquote&gt;&lt;b&gt;Model Portfolio Risk.&lt;/b&gt; The risk that investments selected using quantitative models may perform differently from the market as a whole or from their expected performance. There can be no assurance that use of a quantitative model will enable the fund to achieve positive returns or outperform the market.&lt;/blockquote&gt;&lt;/li&gt;&lt;/ul&gt;&lt;ul type="square"&gt;&lt;li style="margin-left: 5px"&gt;&lt;blockquote&gt;&lt;b&gt;Portfolio Turnover Risk.&lt;/b&gt; The risk that the fund&amp;#8217;s principal investment strategies will result in a consistently high portfolio turnover rate. See the &amp;#8220;Portfolio Turnover&amp;#8221; section above for more information about the impact that portfolio turnover can have on fund performance.&lt;/blockquote&gt;&lt;/li&gt;&lt;/ul&gt;&lt;ul type="square"&gt;&lt;li style="margin-left: 5px"&gt;&lt;blockquote&gt;&lt;b&gt;Sector Focused Investing Risk.&lt;/b&gt; The risk that events negatively affecting an industry or market sector in which the fund focuses its investments will cause the value of the fund&amp;#8217;s shares to decrease, perhaps significantly. To the extent that the fund invests a significant portion of its portfolio in ETFs representing one or more of the primary sectors of the S&amp;amp;P 500&amp;#174; Index (such as consumer discretionary, energy, healthcare) or in an ETF representing U.S. Treasuries, the fund is more vulnerable to conditions that negatively affect such sectors as compared to a fund that is not significantly invested in such sectors.&lt;/blockquote&gt;&lt;/li&gt;&lt;/ul&gt;&lt;ul type="square"&gt;&lt;li style="margin-left: 5px"&gt;&lt;blockquote&gt; &lt;b&gt;U.S. Government Securities Risk.&lt;/b&gt; The risk that U.S. Government securities in the fund&amp;#8217;s portfolio will be subject to price fluctuations, or that an agency or instrumentality will default on an obligation not backed by the full faith and credit of the United States.&lt;/blockquote&gt;&lt;/li&gt;&lt;/ul&gt;</rr:RiskNarrativeTextBlock>

  <rr:RiskNarrativeTextBlock contextRef="Duration_01Feb2012_31Jan2013S000001336_Member">The fund may not achieve its objective, and it is not intended to be a complete investment program. The value of the fund's investments that supports your share value may decrease. If between the time you purchase shares and the time you sell shares the value of the fund's investments decreases, you will lose money. Investment values can decrease for a number of reasons. Conditions affecting the overall economy, specific industries or companies in which the fund invests can be worse than expected, and investments may fail to perform as the adviser expects. As a result, the value of your shares may decrease. The principal risks of investing in the fund are:&lt;ul type="square"&gt;&lt;li style="margin-left: 5px"&gt;&lt;blockquote&gt;&lt;b&gt;Credit Risk. &lt;/b&gt;The risk that the issuer of a security will fail to pay interest or principal in a timely manner, or that negative perceptions of the issuer's ability to make such payments will cause the price of the security to decline.&lt;/blockquote&gt;&lt;/li&gt;&lt;/ul&gt;&lt;ul type="square"&gt;&lt;li style="margin-left: 5px"&gt;&lt;blockquote&gt;&lt;b&gt;Emerging Market Risk. &lt;/b&gt;The risk that prices of emerging markets securities will be more volatile, or will be more greatly affected by negative conditions, than those of their counterparts in more established foreign markets.&lt;/blockquote&gt;&lt;/li&gt;&lt;/ul&gt;&lt;ul type="square"&gt;&lt;li style="margin-left: 5px"&gt;&lt;blockquote&gt;&lt;b&gt;Foreign Investing Risk. &lt;/b&gt;The risk that the prices of foreign securities in the fund's portfolio will be more volatile than those of domestic securities, or will be negatively affected by economic, political or other developments.&lt;/blockquote&gt;&lt;/li&gt;&lt;/ul&gt;&lt;ul type="square"&gt;&lt;li style="margin-left: 5px"&gt;&lt;blockquote&gt;&lt;b&gt;High Yield-High Risk Securities (Junk Bonds) Risk. &lt;/b&gt;The risk that the issuers of high yield-high risk securities in the fund's portfolio will default, that the prices of such securities will be volatile, and that the securities will not be liquid.&lt;/blockquote&gt;&lt;/li&gt;&lt;/ul&gt;&lt;ul type="square"&gt;&lt;li style="margin-left: 5px"&gt;&lt;blockquote&gt;&lt;b&gt;Interest Rate Risk. &lt;/b&gt;The risk that when interest rates rise, the values of the fund's debt securities, especially those with longer maturities, will fall.&lt;/blockquote&gt;&lt;/li&gt;&lt;/ul&gt;&lt;ul type="square"&gt;&lt;li style="margin-left: 5px"&gt;&lt;blockquote&gt;&lt;b&gt;Loan Participation Risk. &lt;/b&gt;The risk that there may not be a readily available market for loan participation interests and, in some cases, the fund may have to dispose of such securities at a substantial discount from face value. Loan participations also involve the credit risk associated with the underlying corporate borrower.&lt;/blockquote&gt;&lt;/li&gt;&lt;/ul&gt;&lt;ul type="square"&gt;&lt;li style="margin-left: 5px"&gt;&lt;blockquote&gt;&lt;b&gt;Long-Term Maturities/Durations Risk. &lt;/b&gt;The risk of greater price fluctuations than would be associated with securities having shorter maturities or durations.&lt;/blockquote&gt;&lt;/li&gt;&lt;/ul&gt;&lt;ul type="square"&gt;&lt;li style="margin-left: 5px"&gt;&lt;blockquote&gt;&lt;b&gt;Market Volatility Risk. &lt;/b&gt;The risk that the value of the securities in which the fund invests may go up or down in response to the prospects of individual companies and/or general economic conditions. Price changes may be temporary or may last for extended periods.&lt;/blockquote&gt;&lt;/li&gt;&lt;/ul&gt;&lt;ul type="square"&gt;&lt;li style="margin-left: 5px"&gt;&lt;blockquote&gt;&lt;b&gt;Mortgage-Backed and Asset-Backed Securities Risk. &lt;/b&gt;The risk that changes in interest rates will cause both extension and prepayment risks for mortgage-backed and asset-backed securities in which the fund invests, or that an impairment of the value of collateral underlying such securities will cause the value of the securities to decrease.&lt;/blockquote&gt;&lt;/li&gt;&lt;/ul&gt;&lt;ul type="square"&gt;&lt;li style="margin-left: 5px"&gt;&lt;blockquote&gt;&lt;b&gt;U.S. Government Securities Risk. &lt;/b&gt;The risk that U.S. Government securities in the fund's portfolio will be subject to price fluctuations, or that an agency or instrumentality will default on an obligation not backed by the full faith and credit of the United States.&lt;/blockquote&gt;&lt;/li&gt;&lt;/ul&gt;</rr:RiskNarrativeTextBlock>

The value of the fund's investments that supports your share value may decrease. If between the time you purchase shares and the time you sell shares the value of the fund's investments decreases, you will lose money. Investment values can decrease for a number of reasons. Conditions affecting the overall economy, specific industries or companies in which the fund invests can be worse than expected, and investments may fail to perform as the subadviser expects. As a result, the value of your shares may decrease. In addition, you will also be subject to the risks associated with the principal investment strategies of any ETFs in which the fund invests. The principal risks of investing in the fund are:&lt;ul type="square"&gt;&lt;li style="margin-left:20px"&gt;&lt;blockquote&gt;&lt;b&gt;Equity Securities Risk.&lt;/b&gt; The risk that events negatively affecting issuers, industries or financial markets in which the fund invests will impact the value of the stocks held by the fund and thus, the value of the fund's shares over short or extended periods.&lt;/blockquote&gt;&lt;/li&gt;&lt;li style="margin-left:20px"&gt;&lt;blockquote&gt;&lt;b&gt;Exchange-Traded Funds (ETFs) Risk.&lt;/b&gt; The risk that the value of an ETF will be more volatile than the underlying portfolio of securities the ETF is designed to track, or that the costs to the fund of owning shares of the ETF will exceed those the fund would incur by investing in such securities directly.&lt;/blockquote&gt;&lt;/li&gt;&lt;li style="margin-left:20px"&gt;&lt;blockquote&gt;&lt;b&gt;Foreign Investing Risk.&lt;/b&gt; The risk that the prices of foreign securities in the fund's portfolio will be more volatile than those of domestic securities, or will be negatively affected by economic, political or other developments.&lt;/blockquote&gt;&lt;/li&gt;&lt;li style="margin-left:20px"&gt;&lt;blockquote&gt;&lt;b&gt;Fund of Funds Risk.&lt;/b&gt; The risk that the underlying funds in which the fund invests will expose the fund to negative performance and additional expenses associated with investment in such funds, and increased volatility.&lt;/blockquote&gt;&lt;/li&gt;&lt;li style="margin-left:20px"&gt;&lt;blockquote&gt;&lt;b&gt;Market Volatility Risk.&lt;/b&gt; The risk that the value of the securities in which the fund invests may go up or down in response to the prospects of individual companies and/or general economic conditions. Price changes may be temporary or may last for extended periods.&lt;/blockquote&gt;&lt;/li&gt;&lt;li style="margin-left:20px"&gt;&lt;blockquote&gt;&lt;b&gt;Model Portfolio Risk.&lt;/b&gt; The risk that investments selected using quantitative models may perform differently from the market as a whole or from their expected performance. There can be no assurance that use of a quantitative model will enable the fund to achieve positive returns or outperform the market.&lt;/blockquote&gt;&lt;/li&gt;&lt;li style="margin-left:20px"&gt;&lt;blockquote&gt;&lt;b&gt;Portfolio Turnover Risk.&lt;/b&gt; The risk that the fund's principal investment strategies will result in a consistently high portfolio turnover rate. See the "Portfolio Turnover" section above for more information about the impact that portfolio turnover can have on fund performance.&lt;/blockquote&gt;&lt;/li&gt;&lt;li style="margin-left:20px"&gt;&lt;blockquote&gt;&lt;b&gt;Small and Medium Market Capitalization Companies.&lt;/b&gt; The risk that the fund's investments in small and medium market capitalization companies will increase the volatility and risk of loss to the fund, as compared with investments in larger, more established companies.&lt;/blockquote&gt;&lt;/li&gt;&lt;/ul&gt;</rr:RiskNarrativeTextBlock>

The fund will invest assets in the equity style with the favorable aggregate score relative to the other style. The ability of the fund to outperform the Russell 3000&lt;sup style="POSITION: relative; BOTTOM: 0.8ex; VERTICAL-ALIGN: baseline"&gt;&amp;#174;&lt;/sup&gt; Index will depend on, among other things, the length of time and degree to which Growth stocks outperform Value stocks or Value stocks outperform Growth stocks in the U.S. equity market.&lt;br/&gt;&lt;br/&gt;  Each allocation may be invested in ETFs and/or baskets of securities representative of such ETFs. The fund may invest in a basket of securities to represent an ETF if it determines that investment in the ETF is not feasible or otherwise not in the best interest of the fund. Under normal circumstances, the fund intends to invest at least 80% of its assets in ETFs and/or securities representative of the U.S. equity market.</rr:StrategyNarrativeTextBlock>

  <rr:RiskNarrativeTextBlock contextRef="Duration_01Feb2012_31Jan2013S000039393_Member">The fund may not achieve its objective, and it is not intended to be a complete investment program. The value of the fund&amp;#8217;s investments that supports your share value may decrease. If between the time you purchase shares and the time you sell shares the value of the fund&amp;#8217;s investments decreases, you will lose money. Investment values can decrease for a number of reasons. Conditions affecting the overall economy, specific industries or companies in which the fund invests can be worse than expected, and investments may fail to perform as the subadviser expects. As a result, the value of your shares may decrease. In addition, you will also be subject to the risks associated with the principal investment strategies of any ETFs in which the fund invests. The principal risks of investing in the fund are:  &lt;ul type="square"&gt;&lt;li style="margin-left: 5px"&gt;&lt;blockquote&gt;  &lt;b&gt;Equity Securities Risk.&lt;/b&gt; The risk that events negatively affecting issuers, industries or financial markets in which the fund invests will impact the value of the stocks held by the fund and thus, the value of the fund&amp;#8217;s shares over short or extended periods.&lt;/blockquote&gt;&lt;/li&gt;&lt;/ul&gt;  &lt;ul type="square"&gt;&lt;li style="margin-left: 5px"&gt;&lt;blockquote&gt;  &lt;b&gt;Exchange-Traded Funds (ETFs) Risk.&lt;/b&gt; The risk that the value of an ETF will be more volatile than the underlying portfolio of securities the ETF is designed to track, or that the costs to the fund of owning shares of the ETF will exceed those the fund would incur by investing in such securities directly.&lt;/blockquote&gt;&lt;/li&gt;&lt;/ul&gt;  &lt;ul type="square"&gt;&lt;li style="margin-left: 5px"&gt;&lt;blockquote&gt;  &lt;b&gt;Fund of Funds Risk.&lt;/b&gt; The risk that the underlying funds in which the fund invests will expose the fund to negative performance and additional expenses associated with investment in such funds, and increased volatility.&lt;/blockquote&gt;&lt;/li&gt;&lt;/ul&gt;  &lt;ul type="square"&gt;&lt;li style="margin-left: 5px"&gt;&lt;blockquote&gt;  &lt;b&gt;Growth Stocks Risk.&lt;/b&gt; The risk that the fund&amp;#8217;s investments in growth stocks will be more volatile than investments in other types of stocks, or will perform differently from the market as a whole and from other types of stocks.&lt;/blockquote&gt;&lt;/li&gt;&lt;/ul&gt;&lt;ul type="square"&gt;&lt;li style="margin-left: 5px"&gt;&lt;blockquote&gt;  &lt;b&gt;Market Volatility Risk.&lt;/b&gt; The risk that the value of the securities in which the fund invests may go up or down in response to the prospects of individual companies and/or general economic conditions. Price changes may be temporary or may last for extended periods.&lt;/blockquote&gt;&lt;/li&gt;&lt;/ul&gt;  &lt;ul type="square"&gt;&lt;li style="margin-left: 5px"&gt;&lt;blockquote&gt;  &lt;b&gt;Model Portfolio Risk.&lt;/b&gt; The risk that investments selected using quantitative models may perform differently from the market as a whole or from their expected performance. There can be no assurance that use of a quantitative model will enable the fund to achieve positive returns or outperform the market.&lt;/blockquote&gt;&lt;/li&gt;&lt;/ul&gt;  &lt;ul type="square"&gt;&lt;li style="margin-left: 5px"&gt;&lt;blockquote&gt;  &lt;b&gt;Portfolio Turnover Risk.&lt;/b&gt; The risk that the fund&amp;#8217;s principal investment strategies will result in a consistently high portfolio turnover rate.

The fund does not pay transaction costs when it buys and sells shares of the underlying mutual funds.

In pursuing this strategy, the fund maintains an emphasis on preservation of capital.&lt;br/&gt;&lt;br/&gt;Allocations are based on a quantitative model that provides a positive or negative signal, on a weekly basis, for each country evaluated. Countries with positive signals will receive allocations approximating their relative weights in the MSCI EAFE&lt;sup style="POSITION: relative; BOTTOM: 0.8ex; VERTICAL-ALIGN: baseline"&gt;&amp;#174;&lt;/sup&gt; Index. The remaining portfolio assets will be allocated to the subadviser&amp;#8217;s &amp;#8220;minimum volatility portfolio,&amp;#8221; which is designed to limit downside risk. The minimum volatility portfolio is allocated equally among the four countries that, in the subadviser&amp;#8217;s opinion, have exhibited the lowest volatility pattern historically. To mitigate concentration, geographic, and political risk, the four countries in the minimum volatility portfolio cannot be from the same geographic or political region.&lt;br/&gt;&lt;br/&gt;Each allocation may be invested in ETFs and/or baskets of securities representative of such ETFs. The fund may invest in a basket of securities to represent an ETF if it determines that investment in the ETF is not feasible or otherwise not in the best interest of the fund.

  <rr:RiskNarrativeTextBlock contextRef="Duration_01Feb2012_31Jan2013S000018969_Member">The fund may not achieve its objective, and it is not intended to be a complete investment program. The value of the fund&amp;#8217;s investments that supports your share value may decrease. If between the time you purchase shares and the time you sell shares the value of the fund&amp;#8217;s investments decreases, you will lose money. Investment values can decrease for a number of reasons. Conditions affecting the overall economy, specific industries or companies in which the fund invests can be worse than expected, and investments may fail to perform as the adviser expects. As a result, the value of your shares may decrease. The principal risks of investing in the fund are:&lt;ul type="square"&gt;&lt;li style="margin-left:20px"&gt;&lt;blockquote&gt;&lt;b&gt;Emerging Market Investing Risk.&lt;/b&gt; The risk that prices of emerging markets securities will be more volatile, or will be more greatly affected by negative conditions, than those of their counterparts in more established foreign markets.&lt;/blockquote&gt;&lt;/li&gt;&lt;li style="margin-left:20px"&gt;&lt;blockquote&gt;&lt;b&gt;Equity-Linked Instruments Risk.&lt;/b&gt; The risk that, in addition to market risk and other risks of the referenced equity security, the fund may experience a return that is different from that of the referenced equity security. Equity-linked instruments also subject the fund to counterparty risk, including the risk that the issuing entity may not be able to honor its financial commitment, which could result in a loss of all or part of the fund&amp;#8217;s investment.&lt;/blockquote&gt;&lt;/li&gt;&lt;li style="margin-left:20px"&gt;&lt;blockquote&gt;&lt;b&gt;Equity Securities Risk.&lt;/b&gt; The risk that events negatively affecting issuers, industries or financial markets in which the fund invests will impact the value of the stocks held by the fund and thus, the value of the fund&amp;#8217;s shares over short or extended periods. Investments in smaller companies may be more volatile than investments in larger companies.&lt;/blockquote&gt;&lt;/li&gt;&lt;li style="margin-left:20px"&gt;&lt;blockquote&gt;&lt;b&gt;Foreign Investing Risk.&lt;/b&gt; The risk that the prices of foreign securities in the fund&amp;#8217;s portfolio will be more volatile than those of domestic securities, or will be negatively affected by economic, political or other developments.&lt;/blockquote&gt;&lt;/li&gt;&lt;li style="margin-left:20px"&gt;&lt;blockquote&gt;&lt;b&gt;Market Volatility Risk.&lt;/b&gt; The risk that the value of the securities in which the fund invests may go up or down in response to the prospects of individual companies and/or general economic conditions. Price changes may be temporary or may last for extended periods.&lt;/blockquote&gt;&lt;/li&gt;&lt;/ul&gt;</rr:RiskNarrativeTextBlock>

The Fixed Income allocation may be invested in ETFs and/or securities representing fixed income sectors including: high yield, investment grade corporate, mortgages, intermediate treasuries and inflation-protected treasuries (TIPS). The Alternative allocation may be invested in ETFs and/or securities representing gold, real estate and broad-based equity securities. The fund may also invest in stocks (without restriction as to market capitalization), bonds (without restriction as to credit quality) and short-term securities. The fund may invest in a basket of securities to represent a sector if it determines that investment in the ETF for that sector is not feasible or otherwise not in the best interest of the fund. The fund may also deviate from a model allocation if it is determined that tracking the model allocation is likely to violate applicable legal or regulatory restrictions or otherwise result in adverse consequences for the fund.

  <rr:RiskNarrativeTextBlock contextRef="Duration_01Feb2012_31Jan2013S000031600_Member">The fund may not achieve its objective, and it is not intended to be a complete investment program. The value of the fund&amp;#8217;s investments that supports your share value may decrease. If between the time you purchase shares and the time you sell shares the value of the fund&amp;#8217;s investments decreases, you will lose money. Investment values can decrease for a number of reasons. Conditions affecting the overall economy, specific industries or companies in which the fund invests can be worse than expected, and investments may fail to perform as the adviser expects. As a result, the value of your shares may decrease. In addition, you will also be subject to the risks associated with the principal investment strategies of any ETFs in which the fund invests. The principal risks of investing in the fund are: &lt;ul type="square"&gt;&lt;li style="margin-left: 5px"&gt;&lt;blockquote&gt;&lt;b&gt;Commodity Risk.&lt;/b&gt; The risk that investments in commodities, such as gold, or commodity-linked notes will subject the fund&amp;#8217;s portfolio to greater volatility than investments in traditional securities, or that commodity-linked instruments will experience returns different from the commodities they attempt to track.&lt;/blockquote&gt;&lt;/li&gt;&lt;/ul&gt;&lt;ul type="square"&gt;&lt;li style="margin-left: 5px"&gt;&lt;blockquote&gt; &lt;b&gt; Credit Risk.&lt;/b&gt; The risk that the issuer of a security will fail to pay interest or principal in a timely manner, or that negative perceptions of the issuer&amp;#8217;s ability to make such payments will cause the price of the security to decline.&lt;/blockquote&gt;&lt;/li&gt;&lt;/ul&gt;&lt;ul type="square"&gt;&lt;li style="margin-left: 5px"&gt;&lt;blockquote&gt; &lt;b&gt;Emerging Market Investing Risk.&lt;/b&gt; The risk that prices of emerging markets securities will be more volatile, or will be more greatly affected by negative conditions, than those of their counterparts in more established foreign markets.&lt;/blockquote&gt;&lt;/li&gt;&lt;/ul&gt;&lt;ul type="square"&gt;&lt;li style="margin-left: 5px"&gt;&lt;blockquote&gt; &lt;b&gt;Equity Securities Risk.&lt;/b&gt; The risk that events negatively affecting issuers, industries or financial markets in which the fund invests, will impact the value of the stocks held by the fund and thus, the value of the fund&amp;#8217;s shares over short or extended periods. Investments in smaller companies may be more volatile than investments in larger companies.&lt;/blockquote&gt;&lt;/li&gt;&lt;/ul&gt;&lt;ul type="square"&gt;&lt;li style="margin-left: 5px"&gt;&lt;blockquote&gt;&lt;b&gt;Exchange-Traded Funds (ETFs) Risk.&lt;/b&gt; The risk that the value of an ETF will be more volatile than the underlying portfolio of securities the ETF is designed to track, or that the costs to the fund of owning shares of the ETF will exceed those the fund would incur by investing in such securities directly.&lt;/blockquote&gt;&lt;/li&gt;&lt;/ul&gt;&lt;ul type="square"&gt;&lt;li style="margin-left: 5px"&gt;&lt;blockquote&gt; &lt;b&gt;Foreign Investing Risk.&lt;/b&gt;  The risk that the prices of foreign securities in the fund&amp;#8217;s portfolio will be more volatile than those of domestic securities, or will be negatively affected by economic, political or other developments.&lt;/blockquote&gt;&lt;/li&gt;&lt;/ul&gt;&lt;ul type="square"&gt;&lt;li style="margin-left: 5px"&gt;&lt;blockquote&gt; &lt;b&gt;High Yield-High Risk Fixed Income Securities Risk.&lt;/b&gt; The risk that the issuers of high yield-high risk securities in the fund&amp;#8217;s portfolio will default, that the prices of such securities will be volatile, and that the securities will not be liquid.&lt;/blockquote&gt;&lt;/li&gt;&lt;/ul&gt;&lt;ul type="square"&gt;&lt;li style="margin-left: 5px"&gt;&lt;blockquote&gt; &lt;b&gt; Interest Rate Risk.&lt;/b&gt; The risk that when interest rates rise, the values of the fund&amp;#8217;s debt securities, especially those with longer maturities, will fall.&lt;/blockquote&gt;&lt;/li&gt;&lt;/ul&gt;&lt;ul type="square"&gt;&lt;li style="margin-left: 5px"&gt;&lt;blockquote&gt; &lt;b&gt;Market Volatility Risk.&lt;/b&gt; The risk that the value of the securities in which the fund invests may go up or down in response to the prospects of individual companies and/or general economic conditions. Price changes may be temporary or may last for extended periods.&lt;/blockquote&gt;&lt;/li&gt;&lt;/ul&gt;&lt;ul type="square"&gt;&lt;li style="margin-left: 5px"&gt;&lt;blockquote&gt;&lt;b&gt;Model Portfolio Risk.&lt;/b&gt; The risk that investments selected using quantitative models may perform differently from the market as a whole or from their expected performance. There can be no assurance that use of a quantitative model will enable the fund to achieve positive returns or outperform the market.&lt;/blockquote&gt;&lt;/li&gt;&lt;/ul&gt;&lt;ul type="square"&gt;&lt;li style="margin-left: 5px"&gt;&lt;blockquote&gt;&lt;b&gt;Portfolio Turnover Risk.&lt;/b&gt; The risk that the fund&amp;#8217;s principal investment strategies will result in a consistently high portfolio turnover rate. See the &amp;#8220;Portfolio Turnover&amp;#8221; section above for more information about the impact that portfolio turnover can have on fund performance.&lt;/blockquote&gt;&lt;/li&gt;&lt;/ul&gt;&lt;ul type="square"&gt;&lt;li style="margin-left: 5px"&gt;&lt;blockquote&gt;&lt;b&gt; Real Estate Investment Risk.&lt;/b&gt; The risk that the value of the fund&amp;#8217;s shares will be negatively affected by factors specific to the real estate market, including interest rate risk, leverage risk, property risk and management risk.&lt;/blockquote&gt;&lt;/li&gt;&lt;/ul&gt;&lt;ul type="square"&gt;&lt;li style="margin-left: 5px"&gt;&lt;blockquote&gt;&lt;b&gt;Sector Focused Investing Risk.&lt;/b&gt; The risk that events negatively affecting a particular industry or market sector in which the fund focuses its investments will cause the value of the fund&amp;#8217;s shares to decrease, perhaps significantly. To the extent that the fund invests a significant portion of its portfolio in ETFs representing one or more of the primary sectors of the S&amp;amp;P 500&amp;#174; Index (such as consumer discretionary, energy, healthcare) or in an ETF representing U.S. Treasuries, the fund is more vulnerable to conditions that negatively affect such sectors as compared to a fund that is not significantly invested in such sectors.&lt;/blockquote&gt;&lt;/li&gt;&lt;/ul&gt;&lt;ul type="square"&gt;&lt;li style="margin-left: 5px"&gt;&lt;blockquote&gt;&lt;b&gt;U.S. Government Securities Risk.&lt;/b&gt; The risk that U.S. Government securities in the fund&amp;#8217;s portfolio will be subject to price fluctuations, or that an agency or instrumentality will default on an obligation not backed by the full faith and credit of the United States.&lt;/blockquote&gt;&lt;/li&gt;&lt;/ul&gt;</rr:RiskNarrativeTextBlock>

The Dow Jones Global Moderate Portfolio Index is a benchmark that takes 60% of the risk of the global securities market. It is a total returns index that is a time-varying weighted average of stocks, bonds, and cash. The Index is the efficient allocation of stocks, bonds, and cash in a portfolio with 60% of the risk of the Dow Jones Aggressive Portfolio Index. The indexes are calculated on a total return basis with dividends reinvested. The indexes are unmanaged and not available for direct investment. &lt;br/&gt;&lt;br/&gt;After-tax returns are calculated using the historical highest individual federal marginal income tax rates and do not reflect the impact of state and local taxes. After-tax returns are shown only for Class A Shares; after-tax returns for other classes will vary. Actual after-tax returns depend on the investor&amp;#8217;s tax situation and may differ from those shown. After-tax returns are not relevant to investors who hold fund shares in tax-deferred accounts or to shares held by non-taxable entities. In certain cases, the Return After Taxes on Distributions and Sale of Fund Shares for a period may be higher than other return figures for the same period. This will occur when a capital loss is realized upon the sale of fund shares and provides an assumed tax benefit that increases the return.</rr:PerformanceTableClosingTextBlock>

After-tax returns are shown only for Class A Shares; after-tax returns for other classes will vary. Actual after-tax returns depend on the investor&amp;#8217;s tax situation and may differ from those shown. After-tax returns are not relevant to investors who hold fund shares in tax-deferred accounts or to shares held by non-taxable entities. In certain cases, the Return After Taxes on Distributions and Sale of Fund Shares for a period may be higher than other return figures for the same period. This will occur when a capital loss is realized upon the sale of fund shares and provides an assumed tax benefit that increases the return.</rr:PerformanceTableClosingTextBlock>

  <rr:RiskNarrativeTextBlock contextRef="Duration_01Feb2012_31Jan2013S000031601_Member">The fund may not achieve its objective, and it is not intended to be a complete investment program. The value of the fund&amp;#8217;s investments that supports your share value may decrease. If between the time you purchase shares and the time you sell shares the value of the fund&amp;#8217;s investments decreases, you will lose money. Investment values can decrease for a number of reasons. Conditions affecting the overall economy, specific industries or companies in which the fund invests can be worse than expected, and investments may fail to perform as the adviser expects. As a result, the value of your shares may decrease. In addition, you will also be subject to the risks associated with the principal investment strategies of any ETFs in which the fund invests. The principal risks of investing in the fund are:&lt;ul type="square"&gt;&lt;li style="margin-left: 5px"&gt;&lt;blockquote&gt;&lt;b&gt;Emerging Market Investing Risk.&lt;/b&gt; The risk that prices of emerging markets securities will be more volatile, or will be more greatly affected by negative conditions, than those of their counterparts in more established foreign markets.&lt;/blockquote&gt;&lt;/li&gt;&lt;/ul&gt;&lt;ul type="square"&gt;&lt;li style="margin-left: 5px"&gt;&lt;blockquote&gt;&lt;b&gt;Equity Securities Risk.&lt;/b&gt; The risk that events negatively affecting issuers, industries or financial markets in which the fund invests, will impact the value of the stocks held by the fund and thus, the value of the fund&amp;#8217;s shares over short or extended periods. Investments in smaller companies may be more volatile than investments in larger companies.&lt;/blockquote&gt;&lt;/li&gt;&lt;/ul&gt;&lt;ul type="square"&gt;&lt;li style="margin-left: 5px"&gt;&lt;blockquote&gt;&lt;b&gt;Exchange-Traded Funds (ETFs) Risk.&lt;/b&gt; The risk that the value of an ETF will be more volatile than the underlying portfolio of securities the ETF is designed to track, or that the costs to the fund of owning shares of the ETF will exceed those the fund would incur by investing in such securities directly.&lt;/blockquote&gt;&lt;/li&gt;&lt;/ul&gt;&lt;ul type="square"&gt;&lt;li style="margin-left: 5px"&gt;&lt;blockquote&gt;&lt;b&gt;Fund of Funds Risk.&lt;/b&gt; The risk that the underlying funds in which the fund invests will expose the fund to negative performance and additional expenses associated with investment in such funds, and increased volatility.&lt;/blockquote&gt;&lt;/li&gt;&lt;/ul&gt;&lt;ul type="square"&gt;&lt;li style="margin-left: 5px"&gt;&lt;blockquote&gt;&lt;b&gt;Foreign Investing Risk.&lt;/b&gt; The risk that the prices of foreign securities in the fund&amp;#8217;s portfolio will be more volatile than those of domestic securities, or will be negatively affected by economic, political or other developments.&lt;/blockquote&gt;&lt;/li&gt;&lt;/ul&gt;&lt;ul type="square"&gt;&lt;li style="margin-left: 5px"&gt;&lt;blockquote&gt;&lt;b&gt;Market Volatility Risk.&lt;/b&gt; The risk that the value of the securities in which the fund invests may go up or down in response to the prospects of individual companies and/or general economic conditions. Price changes may be temporary or may last for extended periods.&lt;/blockquote&gt;&lt;/li&gt;&lt;/ul&gt;&lt;ul type="square"&gt;&lt;li style="margin-left: 5px"&gt;&lt;blockquote&gt;&lt;b&gt;Model Portfolio Risk.&lt;/b&gt; The risk that investments selected using quantitative models may perform differently from the market as a whole or from their expected performance. There can be no assurance that use of a quantitative model will enable the fund to achieve positive returns or outperform the market.&lt;/blockquote&gt;&lt;/li&gt;&lt;/ul&gt;&lt;ul type="square"&gt;&lt;li style="margin-left: 5px"&gt;&lt;blockquote&gt;&lt;b&gt;Portfolio Turnover Risk.&lt;/b&gt; The risk that the fund&amp;#8217;s principal investment strategies will result in a consistently high portfolio turnover rate. See the &amp;#8220;Portfolio Turnover&amp;#8221; section above for more information about the impact that portfolio turnover can have on fund performance.&lt;/blockquote&gt;&lt;/li&gt;&lt;/ul&gt;&lt;ul type="square"&gt;&lt;li style="margin-left: 5px"&gt;&lt;blockquote&gt;&lt;b&gt;Sector Focused Investing Risk.&lt;/b&gt; The risk that events negatively affecting a particular industry or market sector in which the fund focuses its investments will cause the value of the fund&amp;#8217;s shares to decrease, perhaps significantly. To the extent that the fund invests a significant portion of its portfolio in ETFs representing one or more of the primary sectors of the S&amp;amp;P 500&amp;#174; Index (such as consumer discretionary, energy, healthcare) or in an ETF representing U.S. Treasuries, the fund is more vulnerable to conditions that negatively affect such sectors as compared to a fund that is not significantly invested in such sectors.&lt;/blockquote&gt;&lt;/li&gt;&lt;/ul&gt;&lt;ul type="square"&gt;&lt;li style="margin-left: 5px"&gt;&lt;blockquote&gt;&lt;b&gt;U.S. Government Securities Risk.&lt;/b&gt; The risk that U.S. Government securities in the fund&amp;#8217;s portfolio will be subject to price fluctuations, or that an agency or instrumentality will default on an obligation not backed by the full faith and credit of the United States.&lt;/blockquote&gt;&lt;/li&gt;&lt;/ul&gt;</rr:RiskNarrativeTextBlock>

The fund may invest without limit in high yield debt securities and related investments rated below investment grade (that is, securities not rated Baa/BBB or above by at least one nationally recognized statistical rating organization (&amp;#8220;NRSRO&amp;#8221;), or, if unrated, determined to be of comparable credit quality by the subadviser). Below investment grade securities are commonly referred to as &amp;#8220;junk bonds.&amp;#8221; These investments include, but are not limited to, instruments designed to restructure outstanding emerging market debt such as participations in loans between governments and financial institutions. The fund manages duration utilizing a duration neutral strategy. Under normal circumstances, the fund&amp;#8217;s average duration is maintained at a level similar to that of its benchmark, the JP Morgan Emerging Markets Bond Index (EMBI) Global Diversified. As of September 30, 2012, the modified adjusted duration of the JP Morgan EMBI Global Diversified was 7.41 years. The fund is a non-diversified portfolio. &lt;br /&gt;&lt;br /&gt;The fund intends to invest in at least three emerging market countries, which are countries that, at the time of investment, are represented in the JP Morgan Emerging Markets Bond Index Global Diversified or categorized by the World Bank in its annual categorization as middle- or low-income. In determining &amp;#8220;location&amp;#8221; of an issuer, the subadviser primarily relies on the country where the issuer is incorporated. However, the country of risk is ultimately determined based on analysis of the following criteria: actual building address (domicile), primary exchange on which the security is traded and country in which the greatest percentage of company revenue is generated. This evaluation is conducted so as to determine that the issuer&amp;#8217;s assets are exposed to the economic fortunes and risks of the designated country.</rr:StrategyNarrativeTextBlock>

Under normal circumstances, the fund invests globally at least 80% of its assets in stocks of companies principally engaged in the base metals, precious metals, energy, and agriculture group of industries. The fund will concentrate its investments in this commodities-related group of industries. The fund is a non-diversified portfolio and will consist primarily of common and preferred stocks, but may contain commodity-related exchange-traded funds (&amp;#8220;ETFs&amp;#8221;) and commodities-linked notes. The fund will primarily hold securities of companies listed on global securities exchanges or quoted on established over-the-counter markets, or American Depositary Receipts (ADRs). The fund typically invests in the securities of medium to large capitalization companies, but it is not limited to investing in the securities of companies of any particular size.&lt;br /&gt;&lt;br /&gt;Under normal circumstances, the fund will hold at least 40% of its assets in non-U.S issuers and ETFs and/or commodities-linked notes providing exposure to non-U.S markets. The fund intends to diversify its investments among countries and normally have represented in the portfolio business activities of a number of different countries. In determining the &amp;#8220;location&amp;#8221; of an issuer, the subadviser primarily relies on the country where the issuer is incorporated. However, the country of risk is ultimately determined based on analysis of the following criteria: actual building address (domicile), primary exchange on which the security is traded and country in which the greatest percentage of company revenue is generated. This evaluation is conducted so as to determine that the issuer&amp;#8217;s assets are exposed to the economic fortunes and risks of the designated country.</rr:StrategyNarrativeTextBlock>

Conditions affecting the overall economy, specific industries or companies in which the fund invests can be worse than expected, and investments may fail to perform as the subadviser expects. As a result, the value of your shares may decrease. The principal risks of investing in the fund are:  &lt;ul type="square"&gt;&lt;li style="margin-left:20px"&gt;&lt;blockquote&gt;&lt;b&gt;Emerging Market Investing Risk.&lt;/b&gt; The risk that prices of emerging markets securities will be more volatile, or will be more greatly affected by negative conditions, than those of their counterparts in more established foreign markets.&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;b&gt;Equity Securities Risk.&lt;/b&gt; The risk that events negatively affecting issuers, industries or financial markets in which the fund invests will impact the value of the stocks held by the fund and thus, the value of the fund&amp;#8217;s shares over short or extended periods.

  <rr:RiskNarrativeTextBlock contextRef="Duration_01Feb2012_31Jan2013S000030643_Member">The fund may not achieve its objective, and it is not intended to be a complete investment program. The value of the fund&amp;#8217;s investments that supports your share value may decrease. If between the time you purchase shares and the time you sell shares the value of the fund&amp;#8217;s investments decreases, you will lose money. Investment values can decrease for a number of reasons. Conditions affecting the overall economy, specific industries or companies in which the fund invests can be worse than expected, and investments may fail to perform as the adviser expects. As a result, the value of your shares may decrease. The principal risks of investing in the fund are:   &lt;ul type="square"&gt;&lt;li&gt;&lt;blockquote&gt; &lt;b&gt;Commodities Concentration Risk.&lt;/b&gt; The risk that events negatively affecting the base metals, precious metals, energy and agriculture industries in which the fund focuses its investments will cause the value of the fund&amp;#8217;s shares to decrease, perhaps significantly. Since the fund concentrates its assets in commodities-related investments, the fund is more vulnerable to conditions that negatively affect commodities-related companies and investments as compared to a fund that is not significantly invested in such companies.&lt;/blockquote&gt;&lt;/li&gt;&lt;/ul&gt; &lt;ul type="square"&gt;&lt;li&gt;&lt;blockquote&gt; &lt;b&gt;Commodity and Commodity-Linked Instrument Risk.&lt;/b&gt;  The risk that investments in commodities or commodity-linked notes will subject the fund&amp;#8217;s portfolio to greater volatility than investments in traditional securities, or that commodity-linked instruments will experience returns different from the commodities they attempt to track. &lt;/blockquote&gt;&lt;/li&gt;&lt;/ul&gt; &lt;ul type="square"&gt;&lt;li&gt;&lt;blockquote&gt; &lt;b&gt;Emerging Market Investing Risk. &lt;/b&gt; The risk that prices of emerging markets securities will be more volatile, or will be more greatly affected by negative conditions, than those of their counterparts in more established foreign markets. &lt;/blockquote&gt;&lt;/li&gt;&lt;/ul&gt; &lt;ul type="square"&gt;&lt;li&gt;&lt;blockquote&gt; &lt;b&gt; Equity Securities Risk.&lt;/b&gt; The risk that events negatively affecting issuers, industries or financial markets in which the fund invests will impact the value of the stocks held by the fund and thus, the value of the fund&amp;#8217;s shares over short or extended periods. Investments in small and medium-sized companies may be more volatile than investments in larger companies. &lt;/blockquote&gt;&lt;/li&gt;&lt;/ul&gt; &lt;ul type="square"&gt;&lt;li&gt;&lt;blockquote&gt; &lt;b&gt;Exchange-Traded Funds (ETFs) Risk.&lt;/b&gt; The risk that the value of an ETF will be more volatile than the underlying portfolio of securities the ETF is designed to track, or that the costs to the fund of owning shares of the ETF will exceed those the fund would incur by investing in such securities directly. &lt;/blockquote&gt;&lt;/li&gt;&lt;/ul&gt; &lt;ul type="square"&gt;&lt;li&gt;&lt;blockquote&gt; &lt;b&gt;Foreign Investing Risk.&lt;/b&gt; The risk that the prices of foreign securities in the fund&amp;#8217;s portfolio will be more volatile than those of domestic securities, or will be negatively affected by economic, political or other developments.&lt;/blockquote&gt;&lt;/li&gt;&lt;/ul&gt; &lt;ul type="square"&gt;&lt;li&gt;&lt;blockquote&gt;&lt;b&gt; Market Volatility Risk. &lt;/b&gt; The risk that the value of the securities in which the fund invests may go up or down in response to the prospects of individual companies and/or general economic conditions. Price changes may be temporary or may last for extended periods.&lt;/blockquote&gt;&lt;/li&gt;&lt;/ul&gt;&lt;ul type="square"&gt;&lt;li&gt;&lt;blockquote&gt; &lt;b&gt; Non-Diversification Risk.&lt;/b&gt; The risk that the fund will be more susceptible to factors negatively impacting the securities in its portfolio to the extent that each such security represents a significant portion of the fund&amp;#8217;s assets.&lt;/blockquote&gt;&lt;/li&gt;&lt;/ul&gt;</rr:RiskNarrativeTextBlock>

  <rr:StrategyNarrativeTextBlock contextRef="Duration_01Feb2012_31Jan2013S000038115_Member">This fund offers investors exposure to emerging markets. The securities chosen for inclusion in the fund are those that, in the opinion of the subadviser, are high quality companies that pay above average dividends, have above average dividend growth potential, strong balance sheets and cash flow and adhere to better corporate governance. Companies selected must have the financial strength to maintain and grow their dividend payout commitments. The process is focused on identifying companies that have chosen to generate high levels of cash flow and to pay a high proportion of it to their shareholders. It is the belief of the subadviser that those companies offer the best opportunity for capital appreciation as well as superior income generation. &lt;br /&gt;&lt;br /&gt;Under normal circumstances, the fund invests at least 80% of its assets in equity securities of issuers located in emerging markets countries; such issuers may be of any capitalization. The equity securities in which the fund invests include common stocks, preferred stocks and American Depositary Receipts (ADRs). Emerging markets countries generally include every nation in the world except the U.S., Canada, Japan, Australia, New Zealand and most nations located in Western Europe. The fund intends to diversify its investments among countries and normally to have represented in the portfolio business activities of a number of different countries. In determining &amp;#8220;location&amp;#8221; of an issuer, the subadviser primarily relies on the country where the issuer is incorporated. However, the country of risk is ultimately determined based on analysis of the following criteria: actual building address (domicile), primary exchange on which the security is traded and country in which the greatest percentage of company revenue is generated. This evaluation is conducted so as to determine that the issuer&amp;#8217;s assets are exposed to the economic fortunes and risks of the designated country.</rr:StrategyNarrativeTextBlock>

The MSCI ACWI Index (net) is calculated on a total return basis with net dividends reinvested. The indexes are unmanaged and not available for direct investment.&lt;br/&gt;&lt;br/&gt;  After-tax returns are calculated using the historical highest individual federal marginal income tax rates and do not reflect the impact of state and local taxes. After-tax returns are shown only for Class A Shares; after-tax returns for other classes will vary. Actual after-tax returns depend on the investor&amp;#8217;s tax situation and may differ from those shown. After-tax returns are not relevant to investors who hold fund shares in tax-deferred accounts or to shares held by non-taxable entities. In certain cases, the Return After Taxes on Distributions and Sale of Fund Shares for a period may be higher than other return figures for the same period. This will occur when a capital loss is realized upon the sale of fund shares and provides an assumed tax benefit that increases the return.</rr:PerformanceTableClosingTextBlock>

Under normal market conditions, the fund will invest at least 25% of its assets in securities of U.S. issuers. As of September 30, 2012, the fund was invested in issuers representing approximately 13 different countries. Although the fund concentrates its investments in infrastructure companies, it may invest up to 20% of its assets in securities of issuers that are not infrastructure companies, including stocks, debt obligations, money market securities and money market mutual funds, as well as certain derivative instruments. To the extent the fund purchases non-infrastructure stocks, they may be of issuers of any capitalization.

The principal risks of investing in the fund are: &lt;ul type="square"&gt;&lt;li&gt;&lt;blockquote&gt;&lt;b&gt;Credit Risk.&lt;/b&gt; The risk that the issuer of a security will fail to pay interest or principal in a timely manner, or that negative perceptions of the issuer&amp;#8217;s ability to make such payments will cause the price of the security to decline.&lt;/blockquote&gt;&lt;/li&gt;&lt;/ul&gt; &lt;ul type="square"&gt;&lt;li&gt;&lt;blockquote&gt;&lt;b&gt;Derivatives Risk.&lt;/b&gt; The risk that the fund will incur a loss greater than the fund&amp;#8217;s investment in, or will experience greater share price volatility as a result of investing in, a derivative contract. &lt;/blockquote&gt;&lt;/li&gt;&lt;/ul&gt; &lt;ul type="square"&gt;&lt;li&gt;&lt;blockquote&gt;&lt;b&gt;Equity Securities Risk. &lt;/b&gt;The risk that events negatively affecting issuers, industries or financial markets in which the fund invests will impact the value of the stocks held by the fund and thus, the value of the fund&amp;#8217;s shares over short or extended periods. Investments in smaller companies may be more volatile than investments in larger companies.&lt;/blockquote&gt;&lt;/li&gt;&lt;/ul&gt; &lt;ul type="square"&gt;&lt;li&gt;&lt;blockquote&gt;&lt;b&gt;Foreign Investing Risk. &lt;/b&gt; The risk that the prices of foreign securities in the fund&amp;#8217;s portfolio will be more volatile than those of domestic securities, or will be negatively affected by economic, political or other developments. &lt;/blockquote&gt;&lt;/li&gt;&lt;/ul&gt; &lt;ul type="square"&gt;&lt;li&gt;&lt;blockquote&gt;&lt;b&gt;High Yield-High Risk Fixed Income Securities (Junk Bonds) Risk. &lt;/b&gt; The risk that the issuers of high yield-high risk securities in the fund&amp;#8217;s portfolio will default, that the prices of such securities will be volatile, and that the securities will not be liquid. &lt;/blockquote&gt;&lt;/li&gt;&lt;/ul&gt; &lt;ul type="square"&gt;&lt;li&gt;&lt;blockquote&gt;&lt;b&gt;Income Risk. &lt;/b&gt; The risk that income received from the fund will vary widely over the short- and long-term. &lt;/blockquote&gt;&lt;/li&gt;&lt;/ul&gt; &lt;ul type="square"&gt;&lt;li&gt;&lt;blockquote&gt;&lt;b&gt;Industry/Sector Concentration Risk. &lt;/b&gt; The risk that events negatively affecting infrastructure companies will cause the value of the fund&amp;#8217;s shares to decrease, perhaps significantly. Since the fund concentrates its assets in infrastructure companies, the fund is more vulnerable to conditions that negatively affect infrastructure companies as compared to a fund that does not concentrate holdings in such companies. &lt;/blockquote&gt;&lt;/li&gt;&lt;/ul&gt; &lt;ul type="square"&gt;&lt;li&gt;&lt;blockquote&gt;&lt;b&gt;Infrastructure-Related Investment Risk.  &lt;/b&gt;The risk that the value of the fund&amp;#8217;s shares will decrease as a result of conditions, such as general or local economic conditions and political developments, changes in regulations, environmental problems, casualty losses, and changes in interest rates, negatively affecting the infrastructure companies in which the fund invests. &lt;/blockquote&gt;&lt;/li&gt;&lt;/ul&gt; &lt;ul type="square"&gt;&lt;li&gt;&lt;blockquote&gt;&lt;b&gt;Interest Rate Risk. &lt;/b&gt;The risk that when interest rates rise, the values of the fund&amp;#8217;s debt securities, especially those with longer maturities, will fall. &lt;/blockquote&gt;&lt;/li&gt;&lt;/ul&gt; &lt;ul type="square"&gt;&lt;li&gt;&lt;blockquote&gt;&lt;b&gt;Market Volatility Risk. &lt;/b&gt; The risk that the value of the securities in which the fund invests may go up or down in response to the prospects of individual companies and/or general economic conditions. Price changes may be temporary or may last for extended periods. &lt;/blockquote&gt;&lt;/li&gt;&lt;/ul&gt; &lt;ul type="square"&gt;&lt;li&gt;&lt;blockquote&gt;&lt;b&gt;Master Limited Partnership (MLP) Risk. &lt;/b&gt; The risk that the fund&amp;#8217;s investments in MLP units will be negatively impacted by tax law changes, regulatory developments or other factors affecting the MLPs. &lt;/blockquote&gt;&lt;/li&gt;&lt;/ul&gt; &lt;ul type="square"&gt;&lt;li&gt;&lt;blockquote&gt;&lt;b&gt;Preferred Stock Risk. &lt;/b&gt; The risk that a preferred stock will decline in price, fail to pay dividends when expected, or be illiquid. &lt;/blockquote&gt;&lt;/li&gt;&lt;/ul&gt;</rr:RiskNarrativeTextBlock>

The index is calculated on a total-return basis with dividends reinvested. The Global Dividend Linked Benchmark consists of the MSCI World Infrastructure Sector Capped Index for the period since September 1, 2008. This is a market capitalization weighted index that measures performance of global infrastructure companies by capturing broad and diversified opportunities across telecommunication, utilities, energy, transportation and social infrastructure sectors. The telecommunication infrastructure and utilities sector each represent one-third of the index weight, while energy, transportation and social infrastructure sectors have a combined weight of the remaining one-third of the index. Performance of the Global Dividend Linked Benchmark prior to September 1, 2008 represents an allocation consisting of 65% MSCI USA/Utilities Index, 20% MSCI World Telecom Services Index, and 15% MSCI World ex USA/Utilities Index. The indexes are unmanaged and not available for direct investment. &lt;br /&gt;&lt;br /&gt;After-tax returns are calculated using the historical highest individual federal marginal income tax rates and do not reflect the impact of state and local taxes. After-tax returns are shown only for Class A Shares; after-tax returns for other classes will vary. Actual after-tax returns depend on the investor&amp;#8217;s tax situation and may differ from those shown. After-tax returns are not relevant to investors who hold fund shares in tax-deferred accounts or to shares held by non-taxable entities. In certain cases, the Return After Taxes on Distributions and Sale of Fund Shares for a period may be higher than other return figures for the same period. This will occur when a capital loss is realized upon the sale of fund shares and provides an assumed tax benefit that increases the return.</rr:PerformanceTableClosingTextBlock>

  <rr:RiskNarrativeTextBlock contextRef="Duration_01Feb2012_31Jan2013S000038116_Member">The fund may not achieve its objective, and it is not intended to be a complete investment program. The value of the fund&amp;#8217;s investments that supports your share value may decrease. If between the time you purchase shares and the time you sell shares the value of the fund&amp;#8217;s investments decreases, you will lose money. Investment values can decrease for a number of reasons. Conditions affecting the overall economy, specific industries or companies in which the fund invests can be worse than expected, and investments may fail to perform as the subadviser expects. As a result, the value of your shares may decrease. In addition, you will also be subject to the risks associated with the principal investment strategies of any underlying investment companies in which the fund invests. The principal risks of investing in the fund are: &lt;ul type="square"&gt;&lt;li&gt;&lt;blockquote&gt;&lt;b&gt;Fund of Funds Risk.&lt;/b&gt; The risk that the underlying funds in which the fund invests will expose the fund to negative performance and additional expenses associated with investment in such funds, and increased volatility.&lt;/blockquote&gt;&lt;/li&gt;&lt;/ul&gt;&lt;ul type="square"&gt;&lt;li&gt;&lt;blockquote&gt;&lt;b&gt;Closed-End Funds Risk.&lt;/b&gt; The risk that closed-end funds in which the fund invests will expose the fund to negative performance and additional expenses associated with investment in such funds, and increased volatility. Closed-end funds frequently trade at a discount from their net asset value, which may affect whether the fund will realize gain or loss upon its sale of the closed-end funds&amp;#8217; shares. Closed-end funds may employ leverage, which also subjects the closed-end fund to increased risks such as increased volatility.&lt;/blockquote&gt;&lt;/li&gt;&lt;/ul&gt; The principal risks attributable to the underlying investment companies in which the fund invests are:&lt;ul type="square"&gt;&lt;li&gt;&lt;blockquote&gt;&lt;b&gt;Commodity Risk.&lt;/b&gt; The risk that investments in commodities or commodity-linked notes will subject the fund&amp;#8217;s portfolio to greater volatility than investments in traditional securities, or that commodity-linked instruments will experience returns different from the commodities they attempt to track.&lt;/blockquote&gt;&lt;/li&gt;&lt;/ul&gt; &lt;ul type="square"&gt;&lt;li&gt;&lt;blockquote&gt;&lt;b&gt;Convertible Securities Risk.&lt;/b&gt; The fund&amp;#8217;s investments in convertible securities subject the fund to the risks associated with both fixed-income securities and common stocks, in addition to the risk that a convertible security may be called for redemption at a time and price unfavorable to the fund.&lt;/blockquote&gt;&lt;/li&gt;&lt;/ul&gt; &lt;ul type="square"&gt;&lt;li&gt;&lt;blockquote&gt;&lt;b&gt;Credit Risk.&lt;/b&gt; The risk that the issuer of a security will fail to pay interest or principal in a timely manner, or that negative perceptions of the issuer&amp;#8217;s ability to make such payments will cause the price of the security to decline.&lt;/blockquote&gt;&lt;/li&gt;&lt;/ul&gt; &lt;ul type="square"&gt;&lt;li&gt;&lt;blockquote&gt;&lt;b&gt;Derivatives Risk.&lt;/b&gt; The risk that the fund will incur a loss greater than the fund&amp;#8217;s investment in, or will experience greater share price volatility as a result of investing in, a derivative contract.

  <rr:RiskNarrativeTextBlock contextRef="Duration_01Feb2012_31Jan2013S000025108_Member">The fund may not achieve its objectives, and it is not intended to be a complete investment program. The value of the fund&amp;#8217;s investments that supports your share value may decrease. If between the time you purchase shares and the time you sell shares the value of the fund&amp;#8217;s investments decreases, you will lose money. Investment values can decrease for a number of reasons. Conditions affecting the overall economy, specific industries or companies in which the fund invests can be worse than expected, and investments may fail to perform as the adviser expects. As a result, the value of your shares may decrease. The principal risks of investing in the fund are: &lt;ul type="square"&gt;&lt;li style="margin-left:20px"&gt;&lt;blockquote&gt;&lt;b&gt; Emerging Market Investing Risk.&lt;/b&gt; The risk that prices of emerging markets securities will be more volatile, or will be more greatly affected by negative conditions, than those of their counterparts in more established foreign markets.&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;b&gt; Equity REIT Securities Risk.&lt;/b&gt; The risk that, in addition to the risks associated with investing in the real estate industry, the value of the fund&amp;#8217;s shares will be negatively affected by factors specific to investing through a pooled vehicle, such as through poor management of a REIT or REIT-like entity, concentration risk, or other risks typically associated with investing in small or medium market capitalization companies.&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;b&gt; Equity Securities Risk. &lt;/b&gt;The risk that events negatively affecting issuers, industries or financial markets in which the fund invests will impact the value of the stocks held by the fund and thus, the value of the fund&amp;#8217;s shares over short or extended periods. Investments in smaller companies may be more volatile than investments in larger companies.&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;b&gt; Foreign Investing Risk. &lt;/b&gt;The risk that the prices of foreign securities in the fund&amp;#8217;s portfolio will be more volatile than those of domestic securities, or will be negatively affected by economic, political or other developments.&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;b&gt; Geographic Concentration Risk.&lt;/b&gt; The risk that events negatively affecting the geographic location where the fund focuses its investments will cause the value of the fund&amp;#8217;s shares to decrease, perhaps significantly.&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;b&gt; Industry/Sector Concentration Risk.&lt;/b&gt; The risk that events negatively affecting real estate securities will cause the value of the fund&amp;#8217;s shares to decrease, perhaps significantly. Since the fund concentrates its assets in real estate related securities, the fund is more vulnerable to conditions that negatively affect real estate related securities as compared to a fund that does not concentrate holdings in such securities.&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;b&gt; Market Volatility Risk.&lt;/b&gt; The risk that the value of the securities in which the fund invests may go up or down in response to the prospects of individual companies and/or general economic conditions. Price changes may be temporary or may last for extended periods.&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;b&gt; Non-Diversification Risk.&lt;/b&gt; The risk that the fund will be more susceptible to factors negatively impacting the securities in its portfolio to the extent that each such security represents a significant portion of the fund&amp;#8217;s assets.&lt;/blockquote&gt;&lt;/li&gt;&lt;/ul&gt;</rr:RiskNarrativeTextBlock>

The subadviser uses an investment process that focuses on adding value through issue selection, sector/industry selection and opportunistic trading. The fund will generally overweight those sectors and industries where the subadviser identifies well-valued companies whose business profiles are viewed to be improving. The subadviser attempts to maintain the duration of the fund at a level similar to that of its style benchmark, the Barclay&amp;#8217;s Capital U.S. High Yield 2% Issuer Capped Index.

  <rr:StrategyNarrativeTextBlock contextRef="Duration_01Feb2012_31Jan2013S000025110_Member">This fund seeks to offer investors exposure to European market economies through well-established companies. The securities selected for inclusion in the fund are believed by the subadviser to be well-managed businesses with consistent operating histories and financial performance that have favorable long-term economic prospects and, in most cases, generate free cash flow. Over full market cycles, the investment style is designed with the objective of capturing part of the up market cycles and may offer protection in down market cycles. &lt;br/&gt;&lt;br/&gt;Under normal circumstances, at least 80% of the fund&amp;#8217;s assets are invested in equity securities or equity-linked instruments of issuers located in Europe, including issuers in emerging markets countries. Equity-linked securities are hybrid debt securities whose return is connected to an underlying equity, usually a stock. The fund intends to diversify its investments among countries and normally to have represented in the portfolio business activities of a number of different countries. In determining the &amp;#8220;location&amp;#8221; of an issuer, the subadviser primarily relies on the country where the issuer is incorporated. However, the country of risk is ultimately determined based on analysis of the following criteria: actual building address (domicile), primary exchange on which the security is traded and country in which the greatest percentage of company revenue is generated. This evaluation is conducted so as to determine that the issuer&amp;#8217;s assets are exposed to the economic fortunes and risks of the designated country.</rr:StrategyNarrativeTextBlock>

The value of the fund&amp;#8217;s investments that supports your share value may decrease. If between the time you purchase shares and the time you sell shares the value of the fund&amp;#8217;s investments decreases, you will lose money. Investment values can decrease for a number of reasons. Conditions affecting the overall economy, specific industries or companies in which the fund invests can be worse than expected, and investments may fail to perform as the adviser expects. As a result, the value of your shares may decrease. The principal risks of investing in the fund are:&lt;ul type="square"&gt;&lt;li style="margin-left:20px"&gt;&lt;blockquote&gt;&lt;b&gt;Emerging Market Investing Risk.&lt;/b&gt; The risk that prices of emerging markets securities will be more volatile, or will be more greatly affected by negative conditions, than those of their counterparts in more established foreign markets.&lt;/blockquote&gt;&lt;/li&gt;&lt;li style="margin-left:20px"&gt;&lt;blockquote&gt;&lt;b&gt;Equity-Linked Instruments Risk.&lt;/b&gt; The risk that, in addition to market risk and other risks of the referenced equity security, the fund may experience a return that is different from that of the referenced equity security. Equity-linked instruments also subject the fund to counterparty risk, including the risk that the issuing entity may not be able to honor its financial commitment, which could result in a loss of all or part of the fund&amp;#8217;s investment.&lt;/blockquote&gt;&lt;/li&gt;&lt;li style="margin-left:20px"&gt;&lt;blockquote&gt;&lt;b&gt;Equity Securities Risk.&lt;/b&gt; The risk that events negatively affecting issuers, industries or financial markets in which the fund invests will impact the value of the stocks held by the fund and thus, the value of the fund&amp;#8217;s shares over short or extended periods. Investments in smaller companies may be more volatile than investments in larger companies.&lt;/blockquote&gt;&lt;/li&gt;&lt;li style="margin-left:20px"&gt;&lt;blockquote&gt;&lt;b&gt; Foreign Investing Risk.&lt;/b&gt; The risk that the prices of foreign securities in the fund&amp;#8217;s portfolio will be more volatile than those of domestic securities, or will be negatively affected by economic, political or other developments.&lt;/blockquote&gt;&lt;/li&gt;&lt;li style="margin-left:20px"&gt;&lt;blockquote&gt;&lt;b&gt;Geographic Concentration Risk.&lt;/b&gt; The risk that events negatively affecting the geographic location where the fund focuses its investments will cause the value of the fund&amp;#8217;s shares to decrease, perhaps significantly.&lt;/blockquote&gt;&lt;/li&gt;&lt;li style="margin-left:20px"&gt;&lt;blockquote&gt;&lt;b&gt; Market Volatility Risk.&lt;/b&gt; The risk that the value of the securities in which the fund invests may go up or down in response to the prospects of individual companies and/or general economic conditions.

  <rr:PerformanceTableClosingTextBlock contextRef="Duration_01Feb2012_31Jan2013S000018005_Member">The Barclays Capital U.S. Aggregate Bond Index measures the U.S. investment grade fixed rate bond market. The Barclays Capital U.S. High-Yield 2% Issuer Capped Bond Index is a market capitalization-weighted index that measures fixed rate non-investment grade debt securities of U.S. and non-U.S. corporations. No single issuer accounts for more than 2% of market cap. The indexes are calculated on a total return basis. The indexes are unmanaged and not available for direct investment. &lt;br/&gt;&lt;br/&gt; After-tax returns are calculated using the historical highest individual federal marginal income tax rates and do not reflect the impact of state and local taxes. After-tax returns are shown only for Class A Shares; after-tax returns for other classes will vary. Actual after-tax returns depend on the investor&amp;#8217;s tax situation and may differ from those shown. After-tax returns are not relevant to investors who hold fund shares in tax-deferred accounts or to shares held by non-taxable entities. In certain cases, the Return After Taxes on Distributions and Sale of Fund Shares for a period may be higher than other return figures for the same period. This will occur when a capital loss is realized upon the sale of fund shares and provides an assumed tax benefit that increases the return.</rr:PerformanceTableClosingTextBlock>

  <rr:StrategyNarrativeTextBlock contextRef="Duration_01Feb2012_31Jan2013S000025109_Member">This fund seeks to offer investors exposure to Asian market economies, with the exception of Japan, through well-established companies. The portfolio invests in what the subadviser believes to be well-managed businesses with consistent operating histories and financial performance that have favorable long-term economic prospects and, in most cases, generate free cash flow. Over full market cycles, the investment style is designed with the objective of capturing part of the up market cycles and may offer protection in down market cycles.&lt;br /&gt;&lt;br /&gt;Under normal circumstances, at least 80% of the fund&amp;#8217;s assets are invested in equity securities or equity-linked instruments of issuers located in Asia (excluding Japan), including issuers in emerging markets. Equity-linked securities are hybrid debt securities whose return is connected to an underlying equity, usually a stock. The fund intends to diversify its investments among countries and normally to have represented in the portfolio business activities of a number of different countries. In determining the &amp;#8220;location&amp;#8221; of an issuer, the subadviser primarily relies on the country where the issuer is incorporated. However, the country of risk is ultimately determined based on analysis of the following criteria: actual building address (domicile), primary exchange on which the security is traded and country in which the greatest percentage of company revenue is generated. This evaluation is conducted so as to determine that the issuer&amp;#8217;s assets are exposed to the economic fortunes and risks of the designated country.</rr:StrategyNarrativeTextBlock>

The value of the fund&amp;#8217;s investments that supports your share value may decrease. If between the time you purchase shares and the time you sell shares the value of the fund&amp;#8217;s investments decreases, you will lose money. Investment values can decrease for a number of reasons. Conditions affecting the overall economy, specific industries or companies in which the fund invests can be worse than expected, and investments may fail to perform as the adviser expects. As a result, the value of your shares may decrease. The principal risks of investing in the fund are:   &lt;ul type="square"&gt;&lt;li&gt;&lt;blockquote&gt; &lt;b&gt;Emerging Market Investing Risk.&lt;/b&gt; The risk that prices of emerging markets securities will be more volatile, or will be more greatly affected by negative conditions, than those of their counterparts in more established foreign markets.&lt;/blockquote&gt;&lt;/li&gt;&lt;/ul&gt; &lt;ul type="square"&gt;&lt;li&gt;&lt;blockquote&gt; &lt;b&gt;Equity-Linked Instruments Risk. &lt;/b&gt;  The risk that, in addition to market risk and other risks of the referenced equity security, the fund may experience a return that is different from that of the referenced equity security. Equity-linked instruments also subject the fund to counterparty risk, including the risk that the issuing entity may not be able to honor its financial commitment, which could result in a loss of all or part of the fund&amp;#8217;s investment.&lt;/blockquote&gt;&lt;/li&gt;&lt;/ul&gt; &lt;ul type="square"&gt;&lt;li&gt;&lt;blockquote&gt; &lt;b&gt; Equity Securities Risk.  &lt;/b&gt; The risk that events negatively affecting issuers, industries or financial markets in which the fund invests will impact the value of the stocks held by the fund and thus, the value of the fund&amp;#8217;s shares over short or extended periods. Investments in smaller companies may be more volatile than investments in larger companies.&lt;/blockquote&gt;&lt;/li&gt;&lt;/ul&gt; &lt;ul type="square"&gt;&lt;li&gt;&lt;blockquote&gt; &lt;b&gt; Foreign Investing Risk.&lt;/b&gt; The risk that the prices of foreign securities in the fund&amp;#8217;s portfolio will be more volatile than those of domestic securities, or will be negatively affected by economic, political or other developments. &lt;/blockquote&gt;&lt;/li&gt;&lt;/ul&gt; &lt;ul type="square"&gt;&lt;li&gt;&lt;blockquote&gt; &lt;b&gt;Geographic Concentration Risk.&lt;/b&gt; The risk that events negatively affecting the geographic location where the fund focuses its investments will cause the value of the fund&amp;#8217;s shares to decrease, perhaps significantly. &lt;/blockquote&gt;&lt;/li&gt;&lt;/ul&gt; &lt;ul type="square"&gt;&lt;li&gt;&lt;blockquote&gt; &lt;b&gt;Market Volatility Risk. &lt;/b&gt; The risk that the value of the securities in which the fund invests may go up or down in response to the prospects of individual companies and/or general economic conditions.

The subadviser uses a value-driven, absolute return approach to investing. The subadviser&amp;#8217;s process is a mixture of country allocation and stock selection, with a recognition that a significant portion of long-term performance and risk reduction will come from the country allocation decision. &lt;br /&gt;&lt;br /&gt;Under normal circumstances, the fund invests at least 80% of its assets in equity securities of issuers located outside the United States, including issuers in emerging markets countries. The fund intends to diversify its investments among countries and normally to have represented in the portfolio business activities of a number of different countries. In determining the &amp;#8220;location&amp;#8221; of an issuer, the subadviser primarily relies on the country where the issuer is incorporated. However, the country of risk is ultimately determined based on analysis of the following criteria: actual building address (domicile), primary exchange on which the security is traded and country in which the greatest percentage of company revenue is generated. This evaluation is conducted so as to determine that the issuer&amp;#8217;s assets are exposed to the economic fortunes and risks of the designated country.</rr:StrategyNarrativeTextBlock>

The S&amp;amp;P 500&lt;sup style="POSITION: relative; BOTTOM: 0.8ex; VERTICAL-ALIGN: baseline"&gt;&amp;#174;&lt;/sup&gt; Index is calculated on a total return basis with dividends reinvested. The MSCI EAFE&lt;sup style="POSITION: relative; BOTTOM: 0.8ex; VERTICAL-ALIGN: baseline"&gt;&amp;#174;&lt;/sup&gt; Index (net) is a free float-adjusted market capitalization-weighted index that measures developed foreign market equity performance, excluding the U.S. and Canada. The MSCI EAFE&lt;sup style="POSITION: relative; BOTTOM: 0.8ex; VERTICAL-ALIGN: baseline"&gt;&amp;#174;&lt;/sup&gt; Index (net) is calculated on a total return basis with net dividends reinvested. The indexes are unmanaged and not available for direct investment. &lt;br/&gt;&lt;br/&gt;After-tax returns are calculated using the historical highest individual federal marginal income tax rates and do not reflect the impact of state and local taxes. After-tax returns are shown only for Class A Shares; after-tax returns for other classes will vary. Actual after-tax returns depend on the investor&amp;#8217;s tax situation and may differ from those shown. After-tax returns are not relevant to investors who hold fund shares in tax-deferred accounts or to shares held by non-taxable entities. In certain cases, the Return After Taxes on Distributions and Sale of Fund Shares for a period may be higher than other return figures for the same period. This will occur when a capital loss is realized upon the sale of fund shares and provides an assumed tax benefit that increases the return.</rr:PerformanceTableClosingTextBlock>

  <rr:StrategyNarrativeTextBlock contextRef="Duration_01Feb2012_31Jan2013S000038118_Member">The fund pursues capital appreciation in the small-cap international arena. The fund invests in a select group of small-cap companies believed by the subadviser to be undervalued relative to their future market growth potential. The investment strategy emphasizes companies that the subadviser believes to have a sustainable competitive advantage, strong management and low financial risk and to be able to grow over market cycles.&lt;br/&gt;&lt;br/&gt; Under normal circumstances, the fund invests at least 80% of its assets in equity securities of non-U.S. small capitalization companies. As of the date of the Prospectus, the fund&amp;#8217;s subadviser considers small-capitalization companies to be those companies that, at the time of initial purchase, have market capitalizations of between $75 million and $5 billion. The fund intends to diversify its investments among countries and normally to have represented in the portfolio business activities of a number of different countries. In determining &amp;#8220;location&amp;#8221; of an issuer, the subadviser primarily relies on the country where the issuer is incorporated. However, the country of risk is ultimately determined based on analysis of the following criteria: actual building address (domicile), primary exchange on which the security is traded and country in which the greatest percentage of company revenue is generated. This evaluation is conducted so as to determine that the issuer&amp;#8217;s assets are exposed to the economic fortunes and risks of the designated country. Equity securities in which the fund invests include common stocks, preferred stocks and American Depositary Receipts (ADRs). The fund may invest in emerging markets issuers. Generally, the fund invests in approximately 30-60 securities at any given time and invests in issuers in approximately 20 countries.</rr:StrategyNarrativeTextBlock>

  <rr:RiskNarrativeTextBlock contextRef="Duration_01Feb2012_31Jan2013S000029390_Member">The fund may not achieve its objective, and it is not intended to be a complete investment program. The value of the fund&amp;#8217;s investments that supports your share value may decrease. If between the time you purchase shares and the time you sell shares the value of the fund&amp;#8217;s investments decreases, you will lose money. Investment values can decrease for a number of reasons. Conditions affecting the overall economy, specific industries or companies in which the fund invests can be worse than expected, and investments may fail to perform as the adviser expects. As a result, the value of your shares may decrease. In addition, you will also be subject to the risks associated with the principal investment strategies of the exchange-traded funds in which the fund invests. The principal risks of investing in the fund are:&lt;ul type="square"&gt;&lt;li style="margin-left:20px"&gt;&lt;blockquote&gt;&lt;b&gt;Correlation to Index Risk.&lt;/b&gt; The risk that the performance of the fund and its index may vary somewhat due to factors such as fund flows, transaction costs, sample selection, and timing differences associated with additions to and deletions from its index.&lt;/blockquote&gt;&lt;/li&gt;&lt;li style="margin-left:20px"&gt;&lt;blockquote&gt;&lt;b&gt;Equity Securities Risk.&lt;/b&gt; The risk that events negatively affecting issuers, industries or financial markets in which the fund invests, will impact the value of the stocks held by the fund and thus, the value of the fund&amp;#8217;s shares over short or extended periods.&lt;/blockquote&gt;&lt;/li&gt;&lt;li style="margin-left:20px"&gt;&lt;blockquote&gt;&lt;b&gt;Exchange-Traded Funds (ETFs) Risk.&lt;/b&gt; The risk that the value of an ETF will be more volatile than the underlying portfolio of securities the ETF is designed to track, or that the costs to the fund of owning shares of the ETF will exceed those the fund would incur by investing in such securities directly.&lt;/blockquote&gt;&lt;/li&gt;&lt;li style="margin-left:20px"&gt;&lt;blockquote&gt;&lt;b&gt;Fund of Funds Risk.&lt;/b&gt; The risk that the underlying funds in which the fund invests will expose the fund to negative performance and additional expenses associated with investment in such funds, and increased volatility.&lt;/blockquote&gt;&lt;/li&gt;&lt;li style="margin-left:20px"&gt;&lt;blockquote&gt;&lt;b&gt;Market Volatility Risk.&lt;/b&gt; The risk that the value of the securities in which the fund invests may go up or down in response to the prospects of individual companies and/or general economic conditions. Price changes may be temporary or may last for extended periods.&lt;/blockquote&gt;&lt;/li&gt;&lt;li style="margin-left:20px"&gt;&lt;blockquote&gt;&lt;b&gt;Model Portfolio Risk.&lt;/b&gt; The risk that investments selected using quantitative models may perform differently from the market as a whole or from their expected performance. There can be no assurance that use of a quantitative model will enable the fund to achieve positive returns or outperform the market.&lt;/blockquote&gt;&lt;/li&gt;&lt;li style="margin-left:20px"&gt;&lt;blockquote&gt;&lt;b&gt;Portfolio Turnover Risk.&lt;/b&gt; The risk that the fund&amp;#8217;s principal investment strategies will result in a consistently high portfolio turnover rate.
