The term &amp;#8220;investable assets&amp;#8221; in this Prospectus refers to the Fund's net assets plus any borrowings for investment purposes. The Fund's investable assets will be less than its total assets to the extent that it has borrowed money for non-investment purposes, such as to meet anticipated redemptions. &lt;br/&gt;&lt;br/&gt;The Fund employs a &amp;#8220;passively managed&amp;#8221;&amp;#8212;or index&amp;#8212;investment approach. We generally aim to hold the same mix of stocks as is held in the S&amp;amp;P 500 Index. The S&amp;amp;P 500 Index is an unmanaged, market-weighted index of 500 stocks selected by Standard &amp;amp; Poor's Corporation (S&amp;amp;P) on the basis of their market size, liquidity and industry group representation. The S&amp;amp;P 500 Index is widely regarded as representative of the performance of the larger companies in the U.S. stock market as a whole.&lt;br/&gt;&lt;br/&gt; We attempt to trade a security within a reasonable time after it has been added or removed from the Index. The Fund does not necessarily invest in all of the securities in the Index. The Fund may use various investment techniques, including derivatives. The Fund will provide 60 days' prior written notice to shareholders of a change in its non-fundamental policy of investing over 80% of its investable assets in securities included in the S&amp;amp;P 500 Index. &lt;br/&gt;&lt;br/&gt;While we make every effort to achieve our objective, we can't guarantee success.</rr:StrategyNarrativeTextBlock>

  <rr:RiskNarrativeTextBlock contextRef="Duration_01Dec2011_30Nov2012S000004627_Member">All investments have risks to some degree. Please remember that an investment in the Fund is not guaranteed to achieve its investment objective; is not a deposit with a bank; is not insured, endorsed or guaranteed by the Federal Deposit Insurance Corporation or any other government agency; and is subject to investment risks, including possible loss of your original investment. &lt;br/&gt;&lt;br/&gt;&lt;b&gt;Recent Market Events.&lt;/b&gt; The financial crisis that began in 2008 has caused a significant decline in the value and liquidity of many securities. In response to the crisis, the U.S. and other governments and U.S. and foreign central banks have taken steps to support financial markets. The withdrawal of this support, failure of efforts in response to the crisis, or investor perception that such efforts are not succeeding could negatively affect financial markets generally as well as the value and liquidity of certain securities. In addition, policy and legislative changes in the United States and other countries are changing many aspects of financial regulation. The impact of these changes on the markets, and the practical implications for market participants, may not be fully known for some time. &lt;br/&gt;&lt;br/&gt;&lt;b&gt;Risk of Increase in Expenses.&lt;/b&gt; Your actual cost of investing in the Fund may be higher than the expenses shown in the expense table for a variety of reasons. For example, expense ratios may be higher than those shown if average net assets decrease. Net assets are more likely to decrease and Fund expense ratios are more likely to increase when markets are volatile. &lt;br/&gt;&lt;br/&gt;&lt;b&gt;Market Risk.&lt;/b&gt; The securities markets are volatile and the market prices of the Fund&amp;#8217;s securities may decline generally. Securities fluctuate in price based on changes in a company&amp;#8217;s financial condition and overall market and economic conditions. If the market prices of the securities owned by the Fund fall, the value of your investment in the Fund will decline. &lt;br/&gt;&lt;br/&gt;&lt;b&gt;Large Capitalization Company Risk. &lt;/b&gt;Companies with large market capitalizations go in and out of favor based on market and economic conditions. Larger companies tend to be less volatile than companies with smaller market capitalizations. In exchange for this potentially lower risk, the Fund's value may not rise or fall as much as the value of funds that emphasize companies with smaller market capitalizations. &lt;br/&gt;&lt;br/&gt;&lt;b&gt;Equity Securities Risk.&lt;/b&gt; There is the risk that the price of a particular stock the Fund owns could go down and you could lose money. In addition to an individual stock losing value, the value of the equity markets or a sector of them in which the Fund invests could go down. Different sectors of a market can react differently to adverse issuer, market, regulatory, political and economic developments. &lt;br/&gt;&lt;br/&gt;&lt;b&gt;Index Investment Approach.&lt;/b&gt; Since the Fund is passively managed, assets are not allocated from one stock or group of stocks to another based on their prospects, or from stocks into bonds or cash equivalents in an attempt to cushion the impact of a market decline. &lt;br/&gt;&lt;br/&gt;For more information on the risks of investing in this Fund, please see How the Fund Invests&amp;#8212;Investment Risks in the Prospectus and Investment Risks and Considerations in the SAI.</rr:RiskNarrativeTextBlock>
