  <rr:StrategyNarrativeTextBlock contextRef="Duration_27Oct2011_26Oct2012S000038590_Member">The Fund will seek to achieve its investment objective by investing primarily in a diversified portfolio of high yield fixed income instruments that are rated below investment grade by a nationally recognized statistical rating organization (NRSRO) or, if unrated, are considered by the investment subadviser to be of comparable quality. Under normal market conditions, the Fund will invest at least 80% of its investable assets in a diversified portfolio of high yield fixed income instruments that are below investment grade with varying maturities and other investments (including derivatives) with similar economic characteristics. The term &amp;#8220;below investment grade&amp;#8221; in this prospectus refers to instruments either rated Ba1 or lower by Moody&amp;#8217;s Investors Service (Moody&amp;#8217;s), BB+ or lower by Standard &amp;amp; Poor&amp;#8217;s Ratings Services, a division of The McGraw Hill Companies, Inc. (Standard &amp;amp; Poor&amp;#8217;s) or Fitch, Inc. (Fitch), or comparably rated by another NRSRO, or, if unrated, are considered by the investment subadviser to be of comparable quality. The term &amp;#8220;investable assets&amp;#8221; in this prospectus refers to the Fund&amp;#8217;s net assets plus any borrowings for investment purposes. The Fund&amp;#8217;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. Although the Fund may invest in instruments of any duration or maturity, the Fund normally will seek to maintain a weighted average portfolio duration of three years or less and a weighted average maturity of five years or less. The Fund will provide 60 days&amp;#8217; prior written notice to shareholders of a change in the 80% policy stated above. While the Fund makes every effort to achieve its objective, it can&amp;#8217;t guarantee success.&lt;br/&gt;&lt;br/&gt;The types of fixed-income securities in which the Fund may invest include bonds, debentures, notes, commercial paper, floating rate or variable rate instruments and other similar types of debt instruments, as well as loan participations and assignments, money market instruments, payment-in-kind securities and derivatives related to or referencing these types of securities and instruments. The Fund may invest in fixed income instruments of companies or governments. &lt;br/&gt;&lt;br/&gt;In determining which securities to buy and sell, the investment subadviser will consider, among other things, the financial history and condition, earnings trends, analysts' recommendations, and the prospects and the management of an issuer. The investment subadviser generally will employ fundamental analysis in making such determinations. Fundamental analysis involves review of financial statements and other data to attempt to predict an issuer's prospects and to try to decide whether the price of the issuer's security is under-valued or overvalued.</rr:StrategyNarrativeTextBlock>

  <rr:RiskNarrativeTextBlock contextRef="Duration_27Oct2011_26Oct2012S000038590_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 equity and debt capital markets in the United States and internationally have experienced unprecedented volatility. The financial crisis has caused a significant decline in the value and liquidity of many securities. This environment could make identifying investment risks and opportunities especially difficult for the investment subadviser. These market conditions may continue or get worse. 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 could negatively affect the value and liquidity of certain securities. In addition, legislation recently enacted in the United States calls for changes in many aspects of financial regulation. The impact of the legislation on the markets, and the practical implications for market participants, may not be 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; Fixed Income Obligations Risk.&lt;/b&gt; As with credit risk, market risk and interest rate risk, the Fund's holdings, share price, yield and total return may fluctuate in response to bond market movements. The value of bonds may decline for issuer-related reasons, including management performance, financial leverage and reduced demand for the issuer&amp;#8217;s goods and services. Certain types of fixed income obligations also may be subject to call and redemption risk, which is the risk that the issuer may call a bond held by the Fund for redemption before it matures and the Fund may lose income.&lt;br/&gt;&lt;br/&gt;&lt;b&gt; Junk Bonds Risk.&lt;/b&gt; High-yield, high-risk bonds have predominantly speculative characteristics, including particularly high credit risk. Junk bonds tend to be less liquid than higher-rated securities. The liquidity of particular issuers or industries within a particular investment category may shrink or disappear suddenly and without warning. The non-investment grade bond market can experience sudden and sharp price swings and become illiquid due to a variety of factors, including changes in economic forecasts, stock market activity, large sustained sales by major investors, a high profile default or a change in the market's psychology.&lt;br/&gt;&lt;br/&gt;&lt;b&gt; Credit Risk.&lt;/b&gt; This is the risk that the issuer, the guarantor or the insurer of a fixed-income security, or the counterparty to a contract, may be unable or unwilling to make timely principal and interest payments or to otherwise honor its obligations. Additionally, the securities could lose value due to a loss of confidence in the ability of the issuer, guarantor, insurer or counterparty to pay back debt. The longer the maturity and the lower the credit quality of a bond, the more sensitive it is to credit risk.&lt;br/&gt;&lt;br/&gt;&lt;b&gt; Market Risk.&lt;/b&gt; Your investment in Fund shares represents an indirect investment in the securities owned by the Fund. The value of these securities, like other investments, may move up or down, sometimes rapidly and unpredictably. Securities markets are volatile. Your Fund shares at any point in time may be worth less than what you invested, even after taking into account the reinvestment of Fund dividends and distributions. Regardless of how well an individual investment performs, if financial markets go down, you could lose money.&lt;br/&gt;&lt;br/&gt;&lt;b&gt; Foreign Securities Risk.&lt;/b&gt; Investments in securities of non-U.S. issuers (including those denominated in U.S. dollars) generally involve more risk than investing in securities of U.S. issuers. Foreign political, economic and legal systems, especially those in developing and emerging market countries, may be less stable and more volatile than in the U.S. Foreign legal systems generally have fewer regulatory requirements than the U.S. legal system. In general, less information is publicly available about non-U.S. companies than about U.S. companies. Non-U.S. companies generally are not subject to the same accounting, auditing, and financial reporting standards as are U.S. companies. Additionally, the changing value of foreign currencies and changes in exchange rates could also affect the value of the assets the Fund holds and the Fund's performance. Certain foreign countries may impose restrictions on the ability of issuers of foreign securities to make payment of principal and interest or dividends to investors located outside the country, due to blockage of foreign currency exchanges or otherwise. Investments in emerging markets are subject to greater volatility and price declines.&lt;br/&gt;&lt;br/&gt; In addition, the Fund's investments in non-U.S. securities may be subject to the risks of nationalization or expropriation of assets, imposition of currency exchange controls or restrictions on the repatriation of non-U.S. currency, confiscatory taxation and adverse diplomatic developments. Special U.S. tax considerations may apply. &lt;br/&gt;&lt;br/&gt;&lt;b&gt; Interest Rate Risk.&lt;/b&gt; This is the risk that the securities in which the Fund invests could lose value because of interest rate changes. For example, bonds tend to decrease in value if interest rates rise. Debt obligations with longer maturities generally are more sensitive to interest rate changes. In addition, short-term and long-term interest rates do not necessarily move in the same direction or by the same amount. An instrument's reaction to interest rate changes depends on the timing of its interest and principal payments and the current interest rate for each of those time periods. Instruments with floating interest rates can be less sensitive to interest rate changes. Certain types of debt obligations are also subject to prepayment and extension risk. When interest rates fall, the issuers of debt obligations may prepay principal more quickly than expected, and the Fund may be required to reinvest the proceeds at a lower interest rate. This is referred to as &amp;#8220;prepayment risk.&amp;#8221; When interest rates rise, debt obligations may be repaid more slowly than expected, and the value of the Fund's holdings may fall sharply. This is referred to as &amp;#8220;extension risk.&amp;#8221;&lt;br/&gt;&lt;br/&gt;&lt;b&gt; Management Risk. &lt;/b&gt;Actively managed mutual funds are subject to management risk. The subadviser will apply investment techniques and risk analyses in making investment decisions for the Fund, but there can be no guarantee that these techniques will produce the desired results. Additionally, the securities selected by the subadviser may underperform the markets in general, the Fund's benchmark and other mutual funds with similar investment objectives.&lt;br/&gt;&lt;br/&gt;&lt;b&gt; Liquidity Risk.&lt;/b&gt; The Fund may invest in instruments that trade in lower volumes and are less liquid than other investments. Liquidity risk exists when particular investments made by the Fund are difficult to purchase or sell. Liquidity risk also includes the risk that the Fund may make investments that may become less liquid in response to market developments or adverse investor perceptions. If the Fund is forced to sell these investments to pay redemption proceeds or for other reasons, the Fund may lose money. In addition, when there is no willing buyer and investments cannot be readily sold at the desired time or price, the Fund may have to accept a lower price or may not be able to sell the instrument at all. An inability to sell a portfolio position can adversely affect the Fund's value or prevent the Fund from being able to take advantage of other investment opportunities.&lt;br/&gt;&lt;br/&gt; For more information on the risks of investing in this Fund, please see &lt;font style="font-style: italic"&gt;How the Fund Invests&amp;#8212;Investment Risks&lt;/font&gt; in the Prospectus and &lt;font style="font-style: italic"&gt;Investment Risks and Considerations &lt;/font&gt;in the SAI.</rr:RiskNarrativeTextBlock>
  <rr:StrategyNarrativeTextBlock contextRef="Duration_27Oct2011_26Oct2012S000004516_Member">To achieve the Fund's income objective, we invest, under normal circumstances, at least 80% of the Fund's investable assets in a diversified portfolio of high yield fixed-income instruments rated Ba or lower by Moody's Investors Service (Moody's) or BB or lower by Standard &amp;amp; Poor's Ratings Group (Standard &amp;amp; Poor's), and instruments either rated by another major rating service or considered by us to be of comparable quality, that is, junk bonds. 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. The Fund will provide 60 days' prior written notice to shareholders of a change in the 80% policy stated above. While the Fund makes every effort to achieve its objectives, it can't guarantee success.&lt;br/&gt;&lt;br/&gt;In determining which securities to buy and sell, the investment subadviser will consider, among other things, the financial history and condition, earnings trends, analysts' recommendations, and the prospects and the management of an issuer. The investment subadviser generally will employ fundamental analysis in making such determinations. Fundamental analysis involves review of financial statements and other data to attempt to predict an issuer's prospects and to try to decide whether the price of the issuer's security is under-valued or overvalued.</rr:StrategyNarrativeTextBlock>

  <rr:RiskNarrativeTextBlock contextRef="Duration_27Oct2011_26Oct2012S000004516_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 equity and debt capital markets in the United States and internationally have experienced unprecedented volatility. The financial crisis has caused a significant decline in the value and liquidity of many securities. This environment could make identifying investment risks and opportunities especially difficult for the investment subadviser. These market conditions may continue or get worse. 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 could negatively affect the value and liquidity of certain securities. In addition, legislation recently enacted in the United States calls for changes in many aspects of financial regulation. The impact of the legislation on the markets, and the practical implications for market participants, may not be 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; Fixed Income Obligations Risk.&lt;/b&gt; As with credit risk, market risk and interest rate risk, the Fund's holdings, share price, yield and total return may fluctuate in response to bond market movements. The value of bonds may decline for issuer-related reasons, including management performance, financial leverage and reduced demand for the issuer&amp;#8217;s goods and services. Certain types of fixed income obligations also may be subject to call and redemption risk, which is the risk that the issuer may call a bond held by the Fund for redemption before it matures and the Fund may lose income.&lt;br /&gt;&lt;br /&gt;&lt;b&gt; Junk Bonds Risk.&lt;/b&gt; High-yield, high-risk bonds have predominantly speculative characteristics, including particularly high credit risk. Junk bonds tend to be less liquid than higher-rated securities. The liquidity of particular issuers or industries within a particular investment category may shrink or disappear suddenly and without warning. The non-investment grade bond market can experience sudden and sharp price swings and become illiquid due to a variety of factors, including changes in economic forecasts, stock market activity, large sustained sales by major investors, a high profile default or a change in the market's psychology.&lt;br /&gt;&lt;br /&gt;&lt;b&gt; Credit Risk. &lt;/b&gt;This is the risk that the issuer, the guarantor or the insurer of a fixed-income security, or the counterparty to a contract, may be unable or unwilling to make timely principal and interest payments or to otherwise honor its obligations. Additionally, the securities could lose value due to a loss of confidence in the ability of the issuer, guarantor, insurer or counterparty to pay back debt. The longer the maturity and the lower the credit quality of a bond, the more sensitive it is to credit risk.&lt;br /&gt;&lt;br /&gt;&lt;b&gt; Market Risk.&lt;/b&gt; Your investment in Fund shares represents an indirect investment in the securities owned by the Fund.
