Under normal market conditions, the Fund invests primarily in mortgage-backed &lt;/span&gt;&lt;span style="color:#000000;font-family:Times New Roman;font-size:10pt;"&gt;securities (MBS) of investment-grade quality and seeks to provide returns consistent with investments in the market for U.S. home mortgages. The Fund will invest in MBS that are issued or guaranteed by U.S. government agencies or U.S. government-sponsored enterprises (GSEs), including collateralized mortgage obligations (CMOs). The Fund also may invest in U.S. government securities and certain derivative instruments.&lt;/span&gt;&lt;span style="font-family:Times New Roman;font-size:10pt;margin-left:10pt;"&gt;The Fund typically seeks to maintain an overall average dollar-weighted portfolio duration that is within one year above &lt;/span&gt;&lt;span style="font-family:Times New Roman;font-size:10pt;"&gt;or below the Bloomberg U.S. Mortgage-Backed Securities Index (the &#x201c;Index&#x201d;). At times, the Fund&#x2019;s investment adviser&#x2019;s (the &#x201c;Adviser&#x201d;) calculation of portfolio duration may result in variances outside this range. Duration is a measure of the price volatility of a fixed-income security as a result of changes in market rates of interest, based on the weighted average timing of the instrument&#x2019;s expected fixed interest and principal payments. The Adviser seeks to create a portfolio, consisting of MBS, derivative instruments and other securities that outperforms the Index.&lt;/span&gt;&lt;span style="color:#000000;font-family:Times New Roman;font-size:10pt;margin-left:10pt;"&gt;Based on fundamental analysis, the Adviser will consider a variety of factors when making decisions to purchase or sell &lt;/span&gt;&lt;span style="color:#000000;font-family:Times New Roman;font-size:10pt;"&gt;particular securities or derivative contracts. The Fund may, but is not required to, use derivative instruments. Derivatives are instruments that have a value based on another instrument, exchange rate or index, and may be used as substitutes for securities in which the Fund can invest, or to hedge against a potential loss in the underlying asset. There can be no assurance that the Fund&#x2019;s use of derivative instruments will work as intended. Derivative investments made by the Fund are included within the Fund&#x2019;s 80% policy (as described below) and are calculated at market value.&lt;/span&gt;&lt;span style="color:#000000;font-family:Times New Roman;font-size:10pt;margin-left:10pt;"&gt;The Fund will invest its assets so that at least 80% of its net assets (plus any borrowings for investment purposes) are &lt;/span&gt;&lt;span style="color:#000000;font-family:Times New Roman;font-size:10pt;"&gt;invested in U.S. Government securities.&lt;/span&gt;&lt;span style="color:#000000;font-family:Times New Roman;font-size:10pt;margin-left:10pt;"&gt;The Fund will notify shareholders at least 60 days in advance of any change in its investment policy that would enable &lt;/span&gt;&lt;span style="color:#000000;font-family:Times New Roman;font-size:10pt;"&gt;the Fund to invest, under normal circumstances, less than 80% of its net assets (plus any borrowings for investment purposes) in U.S. Government securities.&lt;/span&gt;</rr:StrategyNarrativeTextBlock>

Therefore, it is possible to lose money by investing in the Fund.&lt;/span&gt;&lt;span style="color:#000000;font-family:Times New Roman;font-size:10pt;"&gt; The primary factors that may reduce the Fund&#x2019;s returns include:&lt;/span&gt;&lt;span style="color:#000000;font-family:Times New Roman;font-size:10pt;margin-left:-11.04pt;position:relative;top:1pt;"&gt;&#x25fe;&#x2002;&lt;/span&gt;&lt;span style="color:#000000;font-family:Times New Roman;font-size:10pt;font-weight:bold;"&gt;MBS Risk.&lt;/span&gt;&lt;span style="color:#000000;font-family:Times New Roman;font-size:10pt;"&gt; A rise in interest rates may cause the value of MBS held by the Fund to decline. Certain MBS issued by GSEs are not backed by the full faith and credit of the U.S. government. The Fund&#x2019;s investments in collateralized mortgage obligations (CMOs) may entail greater market, prepayment and liquidity risks than other MBS.&lt;/span&gt;&lt;span style="color:#000000;font-family:Times New Roman;font-size:10pt;margin-left:-11.04pt;position:relative;top:1pt;"&gt;&#x25fe;&#x2002;&lt;/span&gt;&lt;span style="color:#000000;font-family:Times New Roman;font-size:10pt;font-weight:bold;"&gt;Credit Risk. &lt;/span&gt;&lt;span style="color:#000000;font-family:Times New Roman;font-size:10pt;"&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&#x2019;s portfolio holdings, its share price and its performance.&lt;/span&gt;&lt;span style="color:#000000;font-family:Times New Roman;font-size:10pt;margin-left:-11.04pt;position:relative;top:1pt;"&gt;&#x25fe;&#x2002;&lt;/span&gt;&lt;span style="color:#000000;font-family:Times New Roman;font-size:10pt;font-weight:bold;"&gt;Counterparty Risk.&lt;/span&gt;&lt;span style="color:#000000;font-family:Times New Roman;font-size:10pt;"&gt; Counterparty risk includes the possibility that a party to a transaction involving the Fund will fail to meet its obligations. This could cause the Fund to lose money or to lose the benefit of the transaction or prevent the Fund from selling or buying other securities to implement its investment strategy.&lt;/span&gt;&lt;span style="color:#000000;font-family:Times New Roman;font-size:10pt;margin-left:-11.04pt;position:relative;top:1pt;"&gt;&#x25fe;&#x2002;&lt;/span&gt;&lt;span style="color:#000000;font-family:Times New Roman;font-size:10pt;font-weight:bold;"&gt;Risk of Investing in Certain MBS.&lt;/span&gt;&lt;span style="color:#000000;font-family:Times New Roman;font-size:10pt;"&gt; MBS backed by participations in reverse mortgages may carry risks different from and in addition to risks of other MBS. The timing of payments made on reverse mortgage loans (and, by extension, MBS backed by such loans) is uncertain and may occur sooner or later than anticipated.&lt;/span&gt;&lt;span style="color:#000000;font-family:Times New Roman;font-size:10pt;margin-left:-11.04pt;position:relative;top:1pt;"&gt;&#x25fe;&#x2002;&lt;/span&gt;&lt;span style="color:#000000;font-family:Times New Roman;font-size:10pt;font-weight:bold;"&gt;Interest Rate Risk.&lt;/span&gt;&lt;span style="color:#000000;font-family:Times New Roman;font-size:10pt;"&gt; Prices of fixed-income securities generally fall when interest rates rise. The longer the duration of a fixed-income security, the more susceptible it is to interest rate risk. Recent and potential future changes in monetary policy made by central banks and/or their governments are likely to affect the level of interest rates.&lt;/span&gt;&lt;span style="color:#000000;font-family:Times New Roman;font-size:10pt;margin-left:-11.04pt;position:relative;top:1pt;"&gt;&#x25fe;&#x2002;&lt;/span&gt;&lt;span style="color:#000000;font-family:Times New Roman;font-size:10pt;font-weight:bold;"&gt;Prepayment and Extension Risk.&lt;/span&gt;&lt;span style="color:#000000;font-family:Times New Roman;font-size:10pt;"&gt; When homeowners prepay their mortgages in response to lower interest rates, the Fund may be required to reinvest the proceeds at the lower interest rates then available. Also, when interest rates fall, the price of mortgage-backed securities may not rise to as great an extent as other fixed-income securities. When interest rates rise, homeowners are less likely to prepay their mortgages. A decreased rate of prepayments lengthens the expected maturity of a mortgage-backed security, and the price of mortgage-backed securities may decrease more than the price of other fixed income securities when interest rates rise.&lt;/span&gt;&lt;span style="color:#000000;font-family:Times New Roman;font-size:10pt;margin-left:-11.04pt;position:relative;top:1pt;"&gt;&#x25fe;&#x2002;&lt;/span&gt;&lt;span style="color:#000000;font-family:Times New Roman;font-size:10pt;font-weight:bold;"&gt;Liquidity Risk.&lt;/span&gt;&lt;span style="color:#000000;font-family:Times New Roman;font-size:10pt;"&gt; The CMOs in which the Fund invests may be less readily marketable and may be subject to greater fluctuation in price than other securities.&lt;/span&gt;&lt;span style="color:#000000;font-family:Times New Roman;font-size:10pt;margin-left:-11.04pt;position:relative;top:1pt;"&gt;&#x25fe;&#x2002;&lt;/span&gt;&lt;span style="color:#000000;font-family:Times New Roman;font-size:10pt;font-weight:bold;"&gt;Leverage Risk.&lt;/span&gt;&lt;span style="color:#000000;font-family:Times New Roman;font-size:10pt;"&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&#x2019;s risk of loss and potential for gain.&lt;/span&gt;&lt;span style="color:#000000;font-family:Times New Roman;font-size:10pt;margin-left:-11.04pt;position:relative;top:1pt;"&gt;&#x25fe;&#x2002;&lt;/span&gt;&lt;span style="color:#000000;font-family:Times New Roman;font-size:10pt;font-weight:bold;"&gt;Risk of Investing in Derivative Instruments.&lt;/span&gt;&lt;span style="color:#000000;font-family:Times New Roman;font-size:10pt;"&gt; Derivative contracts 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 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.
