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>

Investment values can decrease for a number of reasons.

The principal risks of investing in the fund are:&lt;ul type="square"&gt;&lt;li&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;/li&gt;&lt;/ul&gt;&lt;ul type="square"&gt;&lt;li&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;/li&gt;&lt;/ul&gt;&lt;ul type="square"&gt;&lt;li&gt;&lt;b&gt;Depositary Receipts.&lt;/b&gt; The risk that investments in foreign companies through depositary receipts will expose the fund to the same risks as direct investment in securities of foreign issuers.&lt;/li&gt;&lt;/ul&gt;&lt;ul type="square"&gt;&lt;li&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;/li&gt;&lt;/ul&gt;&lt;ul type="square"&gt;&lt;li&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.

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.

  <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>

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 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. The principal risks of investing in the fund are:&lt;ul type="square"&gt;&lt;li&gt;&lt;b&gt;Depositary Receipts&lt;/b&gt;.
