The fund may invest in the securities of large, well-known companies offering prospects of long-term earnings growth. However, because higher earnings growth rates are often achieved by small to medium capitalization companies, a significant portion of the fund&amp;#8217;s assets may be invested in the securities of such companies. The fund may invest up to 25% of its net assets (at the time of investment) in foreign securities.</rr:StrategyNarrativeTextBlock>
  <rr:RiskNarrativeTextBlock contextRef="Duration_29Dec2011_28Dec2012S000016235_Member">Risk is inherent in all investing. There is no assurance that the fund will meet its investment objective. The value of your investment in the fund, as well as the amount of return you receive on your investment, may fluctuate significantly. You may lose part or all of your investment in the fund or your investment may not perform as well as other similar investments. The following is a summary description of certain risks of investing in the fund.&lt;br/&gt;&lt;br/&gt;&lt;b&gt;Stock market and equity securities 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. The financial crisis that began in 2008 has caused a significant decline in the value and liquidity of many securities of issuers worldwide. In response to the crisis, the U.S. and other governments and the Federal Reserve and certain foreign central banks have taken steps to support financial markets. The withdrawal of this support, failure of efforts to respond to the crisis, or investor perception that such efforts are not succeeding could also 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 in 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;Market sector risk.&lt;/b&gt; The fund may be significantly overweight or underweight certain companies, industries or market sectors, which may cause the fund&amp;#8217;s performance to be more sensitive to developments affecting those companies, industries or sectors.&lt;br/&gt;&lt;br/&gt;&lt;b&gt;Large capitalization company risk.&lt;/b&gt; Large capitalization companies may fall out of favor with investors.&lt;br/&gt;&lt;br/&gt;&lt;b&gt;Small and medium capitalization company risk.&lt;/b&gt; The fund will be exposed to additional risks as a result of its investments in the securities of small and medium capitalization companies. Small and medium capitalization companies may fall out of favor with investors; may have limited product lines, operating histories, markets or financial resources; or may be dependent upon a limited management group. The prices of securities of small and medium capitalization companies generally are more volatile than those of large capitalization companies and are more likely to be adversely affected than large capitalization companies by changes in earnings results and investor expectations or poor economic or market conditions, including those experienced during a recession. Securities of small and medium capitalization companies may underperform large capitalization companies, may be harder to sell at times and at prices the portfolio managers believe appropriate and may offer greater potential for losses.&lt;br/&gt;&lt;br/&gt;&lt;b&gt;Issuer risk.&lt;/b&gt; The value of a security can go up or down more than the market as a whole and can perform differently from the value of the market as a whole, often due to disappointing earnings reports by the issuer, unsuccessful products or services, loss of major customers, major litigation against the issuer or changes in government regulations affecting the issuer or the competitive environment. The fund may experience a substantial or complete loss on an individual security. Historically, the prices of securities of small and medium capitalization companies have generally gone up or down more than those of large capitalization companies, although even large capitalization companies may fall out of favor with investors.&lt;br/&gt;&lt;br/&gt;&lt;b&gt;Foreign investments risk.&lt;/b&gt; The fund&amp;#8217;s investments in securities of foreign issuers or issuers with significant exposure to foreign markets involve additional risk. Foreign countries in which the fund may invest may have markets that are less liquid, less regulated and more volatile than U.S. markets. The value of the fund&amp;#8217;s investments may decline because of factors affecting the particular issuer as well as foreign markets and issuers generally, such as unfavorable government actions, and political or financial instability. Lack of information may also affect the value of these securities.&lt;br/&gt;&lt;br/&gt;The risks of foreign investments are heightened when investing in issuers in emerging market countries.&lt;br/&gt;&lt;br/&gt;&lt;b&gt;Currency risk.&lt;/b&gt; The value of investments in securities denominated in foreign currencies increases or decreases as the rates of exchange between those currencies and the U.S. dollar change. Currency conversion costs and currency fluctuations could erase investment gains or add to investment losses. Currency exchange rates can be volatile, and are affected by factors such as general economic conditions, the actions of the U.S. and foreign governments or central banks, the imposition of currency controls and speculation.&lt;br/&gt;&lt;br/&gt;&lt;b&gt;Growth investing risk.&lt;/b&gt; The fund&amp;#8217;s growth-oriented investment style may increase the risks of investing in the fund. Growth securities typically are very sensitive to market movements because their market prices tend to reflect future expectations. When it appears those expectations will not be met, the prices of growth securities typically fall. Growth stocks as a group may be out of favor and underperform the overall equity market while the market concentrates on value stocks. Although the fund will not concentrate its investments in any one industry or industry group, it may, like many growth funds, weight its investments toward certain industries, thus increasing its exposure to factors adversely affecting issuers within those industries.&lt;br/&gt;&lt;br/&gt;&lt;b&gt;Liquidity risk.&lt;/b&gt; Some securities held by the fund may be difficult to sell, or illiquid, particularly during times of market turmoil. Illiquid securities may also be difficult to value. If the fund is forced to sell an illiquid asset to meet redemption requests or other cash needs, the fund may be forced to sell at a loss.&lt;br/&gt;&lt;br/&gt;&lt;b&gt;Portfolio selection risk.&lt;/b&gt; The value of your investment may decrease if the subadviser&amp;#8217;s judgment about the attractiveness, value or market trends affecting a particular security, industry or sector or about market movements is incorrect.&lt;br/&gt;&lt;br/&gt;&lt;b&gt;Risk of increase in expenses.&lt;/b&gt; Your actual costs of investing in the fund may be higher than the expenses shown in &amp;#8220;Annual fund operating expenses&amp;#8221; for a variety of reasons. For example, expense ratios may be higher than those shown if a fee limitation is changed or terminated or 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;These risks are discussed in more detail later in this Prospectus or in the SAI.</rr:RiskNarrativeTextBlock>
