  <rr:StrategyNarrativeTextBlock contextRef="Duration_01Feb2012_31Jan2013S000010897_Member">The Fund invests primarily in a diversified portfolio of investment-grade, fixed-income securities, including mortgage-backed securities, corporate debt securities and U.S. government obligations. The Adviser expects that, normally, no more than 15% of the Fund's total assets will be invested in securities that are rated below investment grade. However, the Fund may opportunistically invest up to 25% of its total assets in noninvestment-grade debt securities (otherwise known as "junk bonds" or "leveraged loans"). The amount of any unhedged non-U.S. dollar denominated fixed-income securities and foreign currencies in the Fund's portfolio will normally not exceed 10% of the Fund's total assets. The maximum amount that the Fund may invest in non-U.S. dollar denominated fixed-income securities and foreign currencies is 20% of the Fund's total assets. Investment-grade, fixed-income securities are rated in one of the four highest categories (BBB- or higher) by a nationally recognized statistical rating organization (NRSRO). Noninvestment-grade, fixed-income securities are rated in one of the six lowest categories (BB or lower) by a NRSRO, or in either case if unrated, of comparable quality as determined by the Adviser. The Adviser seeks to enhance the Fund's performance by allocating relatively more of its portfolio to the sector that the Adviser expects to offer the best balance between total return and risk and thus offer the greatest potential for return. The Fund may invest in derivative contracts or hybrid instruments (such as, for example, futures contracts, option contracts and swap contracts) to implement its investment strategies as more fully described herein. The Adviser may lengthen or shorten duration from time to time based on its interest rate outlook, but the Fund has no set duration parameters. Duration measures the price sensitivity of a fixed-income security to changes in interest rates.&lt;br/&gt;&lt;br/&gt;Certain of the government securities in which the Fund invests are not backed by the full faith and credit of the U.S. government, such as those issued by the Federal Home Loan Mortgage Corporation ("Freddie Mac"), the Federal National Mortgage Association ("Fannie Mae") and the Federal Home Loan Bank System. These entities are, however, supported through federal subsidies, loans or other benefits. The Fund may also invest in government securities that are supported by the full faith and credit of the U.S. government, such as those issued by the Government National Mortgage Association ("Ginnie Mae"). Finally, the Fund may invest in a few government securities that have no explicit financial support, but which are regarded as having implied support because the federal government sponsors their activities.&lt;br/&gt;&lt;br/&gt;Because the Fund refers to fixed-income investments in its name, it will notify shareholders at least 60 days in advance of any change in its investment policies that would enable the Fund to normally invest less than 80% of its assets in fixed-income investments.</rr:StrategyNarrativeTextBlock>
  <rr:RiskHeading contextRef="Duration_01Feb2012_31Jan2013S000010897_Member">&lt;b&gt;What are the Main Risks of Investing in the Fund?&lt;/b&gt;</rr:RiskHeading>
  <rr:RiskNarrativeTextBlock contextRef="Duration_01Feb2012_31Jan2013S000010897_Member">All mutual funds take investment risks. Therefore, it is possible to lose money by investing in the Fund. The primary factors that may reduce the Fund's returns include:&lt;ul type="square"&gt;&lt;li style="margin-left: 30px"&gt;&lt;b&gt;Interest Rate Risk.&lt;/b&gt; Prices of fixed-income securities rise and fall in response to changes in the interest rate paid by similar securities. Generally, when interest rates rise, prices of fixed-income securities fall.&lt;/li&gt;&lt;/ul&gt;&lt;ul type="square"&gt;&lt;li style="margin-left: 30px"&gt;&lt;b&gt;Prepayment Risk.&lt;/b&gt; When homeowners prepay their mortgages in response to lower interest rates, the Fund will be required to reinvest the proceeds at the lower interest rates available. Also, when interest rates fall, the price of mortgage-backed securities may not rise to as great an extent as that of other fixed-income securities. &lt;/li&gt;&lt;/ul&gt;&lt;ul type="square"&gt;&lt;li style="margin-left: 30px"&gt;&lt;b&gt;Credit Risk.&lt;/b&gt; It is possible that interest or principal on securities will not be paid when due. Such non-payment or default may reduce the value of the Fund's portfolio holdings, its share price and its performance.&lt;/li&gt;&lt;/ul&gt;&lt;ul type="square"&gt;&lt;li style="margin-left: 30px"&gt;&lt;b&gt;Liquidity Risk.&lt;/b&gt; The fixed-income securities in which the Fund invests may be less readily marketable and may be subject to greater fluctuation in price than other securities. Liquidity risk also refers to the possibility that the Fund may not be able to sell a security or close out a derivative contract when it wants to. If this happens, the Fund could incur losses. &lt;/li&gt;&lt;/ul&gt;&lt;ul type="square"&gt;&lt;li style="margin-left: 30px"&gt;&lt;b&gt;Risk of Inflation-Protected Bonds.&lt;/b&gt; The value of inflation-protected bonds is subject to the effects of changes in market interest rates caused by factors other than inflation ("real interest rates"). If interest rates rise due to reasons other than inflation, the Fund's investment in these bonds may not be protected to the extent that the increase is not reflected in the bond's inflation measure.&lt;/li&gt;&lt;/ul&gt;&lt;ul type="square"&gt;&lt;li style="margin-left: 30px"&gt;&lt;b&gt;Risk of Investing in Loans.&lt;/b&gt; In addition to the risks generally associated with debt instruments, such as credit, market, interest rate, liquidity and derivatives risks, bank loans are also subject to the risk that the value of the collateral securing a loan may decline, be insufficient to meet the obligations of the borrower or be difficult to liquidate. The Fund's access to the collateral may be limited by bankruptcy, other insolvency laws or by the type of loan the Fund has purchased. For example, if the Fund purchases a participation instead of an assignment, it would not have direct access to collateral of the borrower. As a result, a floating rate loan may not be fully collateralized and can decline significantly in value. Loans generally are subject to legal or contractual restrictions on resale.&lt;/li&gt;&lt;/ul&gt;&lt;ul type="square"&gt;&lt;li style="margin-left: 30px"&gt;&lt;b&gt;Loan Liquidity Risk.&lt;/b&gt; Loans generally are subject to legal or contractual restrictions on resale. The liquidity of loans, including the volume and frequency of secondary market trading in such loans, varies significantly over time and among individual loans.&lt;/li&gt;&lt;/ul&gt;&lt;ul type="square"&gt;&lt;li style="margin-left: 30px"&gt;&lt;b&gt;Loan Prepayment Risk.&lt;/b&gt; During periods of declining interest rates or for other purposes, borrowers may exercise their option to prepay principal earlier than scheduled which may force the Fund to reinvest in lower-yielding instruments.&lt;/li&gt;&lt;/ul&gt;&lt;ul type="square"&gt;&lt;li style="margin-left: 30px"&gt;&lt;b&gt;Agency Insolvency Risk.&lt;/b&gt; In a syndicated loan, the agent bank is the bank in the syndicate that undertakes the bulk of the administrative duties involved in the day-to-day administration of the loan. In the event of the insolvency of an agent bank, a loan could be subject to settlement risk as well as the risk of interruptions in the administrative duties performed in the day-to-day administration of the loan (such as processing interest rate calculations, processing draws, pursuing certain available contractual remedies, etc.).&lt;/li&gt;&lt;/ul&gt;&lt;ul type="square"&gt;&lt;li style="margin-left: 30px"&gt;&lt;b&gt;Risk Associated with Noninvestment-Grade Securities.&lt;/b&gt; The Fund may invest a portion of its assets in securities rated below investment grade which may be subject to greater interest rate, credit and liquidity risks than investment-grade securities.&lt;/li&gt;&lt;/ul&gt;&lt;ul type="square"&gt;&lt;li style="margin-left: 30px"&gt;&lt;b&gt;Risk Related to the Economy. &lt;/b&gt;Lower-grade bond returns are sensitive to changes in the economy. The value of the Fund's portfolio may decline in tandem with a drop in the overall value of the stock market based on negative developments in the U.S. and global economies.&lt;/li&gt;&lt;/ul&gt;&lt;ul type="square"&gt;&lt;li style="margin-left: 30px"&gt;&lt;b&gt;Risk of Foreign Investing.&lt;/b&gt; Because the Fund invests in securities issued by foreign companies, the Fund's share price may be more affected by foreign economic and political conditions, taxation policies and accounting and auditing standards than would otherwise be the case.&lt;/li&gt;&lt;/ul&gt;&lt;ul type="square"&gt;&lt;li style="margin-left: 30px"&gt;&lt;b&gt;Currency Risk.&lt;/b&gt; Exchange rates for currencies fluctuate daily. Accordingly, the Fund may experience increased volatility with respect to the value of its Shares and its returns as a result of its exposure to foreign currencies through direct holding of such currencies or holding of non-U.S. dollar denominated securities. &lt;/li&gt;&lt;/ul&gt;&lt;ul type="square"&gt;&lt;li style="margin-left: 30px"&gt;&lt;b&gt;Eurozone Related Risk.&lt;/b&gt; A number of countries in the European Union (EU) have experienced, and may continue to experience, severe economic and financial difficulties. Additional EU member countries may also fall subject to such difficulties. These events could negatively affect the value and liquidity of the Fund's investments in euro-denominated securities and derivatives contracts, securities of issuers located in the EU or with significant exposure to EU issuers or countries.&lt;/li&gt;&lt;/ul&gt;&lt;ul type="square"&gt;&lt;li style="margin-left: 30px"&gt;&lt;b&gt;Risk of Investing in Emerging Market Countries.&lt;/b&gt; Securities issued or traded in emerging markets generally entail greater risks than securities issued or traded in developed markets. Emerging market economies may also experience more severe downturns (with corresponding currency devaluations) than developed economies.&lt;/li&gt;&lt;/ul&gt;&lt;ul type="square"&gt;&lt;li style="margin-left: 30px"&gt;&lt;b&gt;Leverage Risk.&lt;/b&gt; Leverage risk is created when an investment exposes the Fund to a level of risk that exceeds the amount invested. Changes in the value of such an investment magnify the Fund's risk of loss and potential for gain.&lt;/li&gt;&lt;/ul&gt;&lt;ul type="square"&gt;&lt;li style="margin-left: 30px"&gt;&lt;b&gt;Risk of Investing in Derivative Contracts and Hybrid Instruments.&lt;/b&gt; Derivative contracts and hybrid instruments involve risks different from, or possibly greater than, risks associated with investing directly in securities and other traditional investments. Specific risk issues related to the use of such contracts and instruments include valuation and tax issues, increased potential for losses and/or costs to the Fund and a potential reduction in gains to the Fund. Each of these issues is described in greater detail in this Prospectus. Derivative contracts and hybrid instruments may also involve other risks described in this Prospectus or the Fund's Statement of Additional Information (SAI), such as interest rate, credit, liquidity and leverage risks.&lt;/li&gt;&lt;/ul&gt;&lt;ul type="square"&gt;&lt;li style="margin-left: 30px"&gt;&lt;b&gt;Risk of Loss after Redemption.&lt;/b&gt; The Fund may also invest in trade finance loan instruments primarily by investing in other investment companies (which are not available for general investment by the public) that owns those instruments and that are advised by an affiliate of the Adviser and is structured as an extended payment fund (EPF). In the EPF, the Fund, as shareholder, will bear the risk of investment loss during the period between when shares of such EPF are presented to the transfer agent of the EPF for redemption and when the net asset value of the EPF is determined for payment of the redeemed EPF shares (the "Redemption Pricing Date").&lt;/li&gt;&lt;/ul&gt;&lt;ul type="square"&gt;&lt;li style="margin-left: 30px"&gt;&lt;b&gt;Technology Risk.&lt;/b&gt; Proprietary and third-party data and systems are utilized to support decision making for the Fund. Data imprecision, software or other technology malfunctions, programming inaccuracies and similar circumstances may impair the performance of these systems, which may negatively affect Fund performance.&lt;/li&gt;&lt;/ul&gt;The Shares offered by this Prospectus are not deposits or obligations of any bank, are not endorsed or guaranteed by any bank and are not insured or guaranteed by the U.S. government, the Federal Deposit Insurance Corporation, the Federal Reserve Board or any other government agency.</rr:RiskNarrativeTextBlock>
