Securities rated in the top four ratings categories by independent rating organizations such as Standard &amp;amp; Poor's ("S&amp;amp;P") (rated BBB or better), Moody's Investors Service ("Moody's") (rated Baa or higher) and Fitch Ratings ("Fitch") (rated BBB or better) are considered investment grade. Securities rated BB or lower by S&amp;amp;P or Fitch or Ba or lower by Moody's are considered to be below investment grade. The Fund may invest up to 20% of total assets in non-investment grade debt securities, including up to 5% in securities rated lower than B by S&amp;amp;P or Fitch or Moody's, which may include defaulted securities. The Fund's focus on the credit quality of its portfolio is intended to reduce credit risk and help to preserve the Fund's capital.&lt;br/&gt;&lt;br/&gt;Debt securities represent the obligation of the issuer to repay a loan of money to it, and generally pay interest to the holder. Bonds, notes and debentures are examples of debt securities. Many of the mortgages purchased by the Fund are generally issued or guaranteed by the U.S. government, its agencies or instrumentalities.&lt;br/&gt;&lt;br/&gt;Many of the mortgage-backed securities in which the Fund will invest are generally issued or guaranteed by the U.S. government. Others are issued and/or backed by U.S. government agencies, such as the Government National Mortgage Association ("GNMA" or "Ginnie Mae") or by U.S. government-sponsored enterprises, such as Fannie Mae and Freddie Mac.&lt;br/&gt;&lt;br/&gt;The Fund may also invest in mortgage dollar rolls. In a mortgage dollar roll, the Fund sells mortgage-backed securities for delivery in the current month and simultaneously contracts to repurchase substantially similar (same type, coupon, and maturity) securities on a specified future date.&lt;br/&gt;&lt;br/&gt;In order to effectively manage cash flows into or out of the Fund, the Fund may buy and sell financial futures contracts or options on such contracts. The Fund uses futures contracts on U.S. Treasury securities to help manage risks relating to interest rates and other market factors, to increase liquidity, to invest in particular markets in more efficient or less expensive ways, and to quickly and efficiently cause new cash to be invested in the securities markets or, if cash will be needed to meet shareholder redemption requests, to remove Fund assets from exposure to the market.&lt;br/&gt;&lt;br/&gt;The Fund may invest a small portion of its assets directly in mortgage loans, may enter into forward currency contracts and currency futures contracts, and may invest in corporate loans.&lt;br/&gt;&lt;br/&gt;The Fund may invest up to 25% of its total assets in foreign securities and up to 20% of its total assets in non-U.S. dollar denominated securities.&lt;/font&gt;</rr:StrategyNarrativeTextBlock>

The value of your investment in the Fund, as well as the amount of return you receive on your investment, may fluctuate significantly from day to day and over time. 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 principal risks of investing in the Fund.&lt;/font&gt;&lt;br/&gt;&lt;ul type="square"&gt;&lt;li style="margin-left:-20px"&gt;&lt;font style="font-family: Arial, Helvetica, sans-serif; font-size: small; "&gt;&lt;i&gt;&lt;b&gt;Corporate Loans Risk &amp;#151;&lt;/b&gt;&lt;/i&gt; Commercial banks and other financial institutions or institutional investors make corporate loans to companies that need capital to grow or restructure. Borrowers generally pay interest on corporate loans at rates that change in response to changes in market interest rates such as the London Interbank Offered Rate ("LIBOR") or the prime rates of U.S. banks. As a result, the value of corporate loan investments is generally less exposed to the adverse effects of shifts in market interest rates than investments that pay a fixed rate of interest. The market for corporate loans may be subject to irregular trading activity, wide bid/ask spreads and extended trade settlement periods.&lt;/font&gt;&lt;/li&gt;&lt;/ul&gt;&lt;ul type="square"&gt;&lt;li style="margin-left:-20px"&gt;&lt;font style="font-family: Arial, Helvetica, sans-serif; font-size: small; "&gt;&lt;i&gt;&lt;b&gt;Credit Risk &amp;#151; &lt;/b&gt;&lt;/i&gt; Credit risk refers to the possibility that the issuer of a security will not be able to make payments of interest and principal when due. Changes in an issuer's credit rating or the market's perception of an issuer's creditworthiness may also affect the value of the Fund's investment in that issuer.&lt;/font&gt;&lt;/li&gt;&lt;/ul&gt;&lt;ul type="square"&gt;&lt;li style="margin-left:-20px"&gt;&lt;font style="font-family: Arial, Helvetica, sans-serif; font-size: small; "&gt;&lt;i&gt;&lt;b&gt;Debt Securities Risk &amp;#151;&lt;/b&gt;&lt;/i&gt; Debt securities, such as bonds, involve credit risk. Credit risk is the risk that the borrower will not make timely payments of principal and interest. Changes in an issuer's credit rating or the market's perception of an issuer's creditworthiness may also affect the value of the Fund's investment in that issuer. The degree of credit risk depends on the issuer's financial condition and on the terms of the securities. Debt securities are also subject to interest rate risk. Interest rate risk is the risk that the value of a debt security may fall when interest rates rise. In general, the market price of debt securities with longer maturities will go up or down more in response to changes in interest rates than the market price of shorter term securities.&lt;/font&gt;&lt;/li&gt;&lt;/ul&gt;&lt;ul type="square"&gt;&lt;li style="margin-left:-20px"&gt;&lt;font style="font-family: Arial, Helvetica, sans-serif; font-size: small; "&gt;&lt;i&gt;&lt;b&gt;Derivatives Risk &amp;#151;&lt;/b&gt;&lt;/i&gt; The Fund's use of derivatives may reduce the Fund's returns and/or increase volatility. Volatility is defined as the characteristic of a security, an index or a market to fluctuate significantly in price within a short time period. Derivatives are also subject to counterparty risk, which is the risk that the other party in the transaction will not fulfill its contractual obligation. A risk of the Fund's use of derivatives is that the fluctuations in their values may not correlate perfectly with the overall securities markets. The possible lack of a liquid secondary market for derivatives and the resulting inability of the Fund to sell or otherwise close a derivatives position could expose the Fund to losses and could make derivatives more difficult for the Fund to value accurately. Derivatives may give rise to a form of leverage and may expose the Fund to greater risk and increase its costs. Recent legislation calls for new regulation of the derivatives markets. The extent and impact of the regulation is not yet known and may not be known for some time. New regulation may make derivatives more costly, may limit the availability of derivatives, or may otherwise adversely affect the value or performance of derivatives.&lt;/font&gt;&lt;/li&gt;&lt;/ul&gt;&lt;ul type="square"&gt;&lt;li style="margin-left:-20px"&gt;&lt;font style="font-family: Arial, Helvetica, sans-serif; font-size: small; "&gt;&lt;i&gt;&lt;b&gt;Dollar Rolls Risk &amp;#151;&lt;/b&gt;&lt;/i&gt; Dollar rolls involve the risk that the market value of the securities that the Fund is committed to buy may decline below the price of the securities the Fund has sold. These transactions may involve leverage.&lt;/font&gt;&lt;/li&gt;&lt;/ul&gt;&lt;ul type="square"&gt;&lt;li style="margin-left:-20px"&gt;&lt;font style="font-family: Arial, Helvetica, sans-serif; font-size: small; "&gt;&lt;i&gt;&lt;b&gt;Extension Risk &amp;#151;&lt;/b&gt;&lt;/i&gt; When interest rates rise, certain obligations will be paid off by the obligor more slowly than anticipated, causing the value of these securities to fall.&lt;/font&gt;&lt;/li&gt;&lt;/ul&gt;&lt;ul type="square"&gt;&lt;li style="margin-left:-20px"&gt;&lt;font style="font-family: Arial, Helvetica, sans-serif; font-size: small; "&gt;&lt;i&gt;&lt;b&gt;Foreign Securities Risk &amp;#151;&lt;/b&gt;&lt;/i&gt; Foreign investments often involve special risks not present in U.S. investments that can increase the chances that the Fund will lose money. These risks include:&lt;/font&gt;&lt;/li&gt;&lt;/ul&gt;&lt;ul type="square"&gt;&lt;li&gt;&lt;font style="font-family: Arial, Helvetica, sans-serif; font-size: small; "&gt;The Fund generally holds its foreign securities and cash in foreign banks and securities depositories, which may be recently organized or new to the foreign custody business and may be subject to only limited or no regulatory oversight.&lt;/font&gt;&lt;/li&gt;&lt;/ul&gt;&lt;ul type="square"&gt;&lt;li&gt;&lt;font style="font-family: Arial, Helvetica, sans-serif; font-size: small; "&gt;Changes in foreign currency exchange rates can affect the value of the Fund's portfolio.&lt;/font&gt;&lt;/li&gt;&lt;/ul&gt;&lt;ul type="square"&gt;&lt;li&gt;&lt;font style="font-family: Arial, Helvetica, sans-serif; font-size: small; "&gt;The economies of certain foreign markets may not compare favorably with the economy of the United States with respect to such issues as growth of gross national product, reinvestment of capital, resources and balance of payments position.&lt;/font&gt;&lt;/li&gt;&lt;/ul&gt;&lt;ul type="square"&gt;&lt;li&gt;&lt;font style="font-family: Arial, Helvetica, sans-serif; font-size: small; "&gt;The governments of certain countries may prohibit or impose substantial restrictions on foreign investments in their capital markets or in certain industries.&lt;/font&gt;&lt;/li&gt;&lt;/ul&gt;&lt;ul type="square"&gt;&lt;li&gt;&lt;font style="font-family: Arial, Helvetica, sans-serif; font-size: small; "&gt;Many foreign governments do not supervise and regulate stock exchanges, brokers and the sale of securities to the same extent as does the United States and may not have laws to protect investors that are comparable to U.S. securities laws.&lt;/font&gt;&lt;/li&gt;&lt;/ul&gt;&lt;ul type="square"&gt;&lt;li&gt;&lt;font style="font-family: Arial, Helvetica, sans-serif; font-size: small; "&gt;Settlement and clearance procedures in certain foreign markets may result in delays in payment for or delivery of securities not typically associated with settlement and clearance of U.S. investments.&lt;/font&gt;&lt;/li&gt;&lt;/ul&gt;&lt;ul type="square"&gt;&lt;li style="margin-left:-20px"&gt;&lt;font style="font-family: Arial, Helvetica, sans-serif; font-size: 8pt; "&gt;&lt;i&gt;High Portfolio Turnover Risk&lt;/i&gt; &amp;#151; The Fund may engage in active and frequent trading of its portfolio securities. High portfolio turnover (more than 100%) may result in increased transaction costs to the Fund, including brokerage commissions, dealer mark-ups and other transaction costs on the sale of the securities and on reinvestment in other securities. The sale of Fund portfolio securities may result in the realization and/or distribution to shareholders of higher capital gains or losses as compared to a fund with less active trading policies. These effects of higher than normal portfolio turnover may adversely affect Fund performance. In addition, investment in mortgage dollar rolls and participation in TBA transactions may significantly increase the Fund's portfolio turnover rate.&lt;/font&gt;&lt;/li&gt;&lt;/ul&gt;&lt;ul type="square"&gt;&lt;li style="margin-left:-20px"&gt;&lt;font style="font-family: Arial, Helvetica, sans-serif; font-size: small; "&gt;&lt;i&gt;&lt;b&gt;Interest Rate Risk &amp;#151;&lt;/b&gt;&lt;/i&gt; Interest rate risk is the risk that prices of bonds and other fixed-income securities will increase as interest rates fall, and decrease as interest rates rise.&lt;/font&gt;&lt;/li&gt;&lt;/ul&gt;&lt;ul type="square"&gt;&lt;li style="margin-left:-20px"&gt;&lt;font style="font-family: Arial, Helvetica, sans-serif; font-size: small; "&gt;&lt;i&gt;&lt;b&gt;Junk Bonds Risk &amp;#151;&lt;/b&gt;&lt;/i&gt; Although junk bonds generally pay higher rates of interest than investment grade bonds, junk bonds are high risk investments that may cause income and principal losses for the Fund.&lt;/font&gt;&lt;/li&gt;&lt;/ul&gt;&lt;ul type="square"&gt;&lt;li style="margin-left:-20px"&gt;&lt;font style="font-family: Arial, Helvetica, sans-serif; font-size: small; "&gt;&lt;i&gt;&lt;b&gt;Market Risk and Selection Risk &amp;#151;&lt;/b&gt;&lt;/i&gt; Market risk is the risk that one or more markets in which the Fund invests will go down in value, including the possibility that the markets will go down sharply and unpredictably. Selection risk is the risk that the securities selected by Fund management will underperform the markets, the relevant indices or the securities selected by other funds with similar investment objectives and investment strategies. This means you may lose money.&lt;/font&gt;&lt;/li&gt;&lt;/ul&gt;&lt;ul type="square"&gt;&lt;li style="margin-left:-20px"&gt;&lt;font style="font-family: Arial, Helvetica, sans-serif; font-size: small; "&gt;&lt;i&gt;&lt;b&gt;Mortgage- and Asset-Backed Securities Risks &amp;#151;&lt;/b&gt;&lt;/i&gt;  Mortgage- and asset-backed securities represent interests in "pools" of mortgages or other assets, including consumer loans or receivables held in trust. Mortgage- and asset-backed securities are subject to credit, interest rate, prepayment and extension risks. These securities also are subject to risk of default on the underlying mortgage or asset, particularly during periods of economic downturn. Small movements in interest rates (both increases and decreases) may quickly and significantly reduce the value of certain mortgage-backed securities.&lt;/font&gt;&lt;/li&gt;&lt;/ul&gt;&lt;ul type="square"&gt;&lt;li style="margin-left:-20px"&gt;&lt;font style="font-family: Arial, Helvetica, sans-serif; font-size: small; "&gt;&lt;i&gt;&lt;b&gt;Prepayment Risk &amp;#151;&lt;/b&gt;&lt;/i&gt;  When interest rates fall, certain obligations will be paid off by the obligor more quickly than originally anticipated, and the Fund may have to invest the proceeds in securities with lower yields.&lt;/font&gt;&lt;/li&gt;&lt;/ul&gt;&lt;ul type="square"&gt;&lt;li style="margin-left:-20px"&gt;&lt;font style="font-family: Arial, Helvetica, sans-serif; font-size: small; "&gt;&lt;i&gt;&lt;b&gt;U.S. Government Issuer Risk &amp;#151; &lt;/b&gt;&lt;/i&gt;  Treasury obligations may differ in their interest rates, maturities, times of issuance and other characteristics. Obligations of U.S. Government agencies and authorities are supported by varying degrees of credit but generally are not backed by the full faith and credit of the U.S. Government. No assurance can be given that the U.S. Government will provide financial support to its agencies and authorities if it is not obligated by law to do so.&lt;/font&gt;&lt;/li&gt;&lt;/ul&gt;&lt;ul type="square"&gt;&lt;li style="margin-left:-20px"&gt;&lt;font style="font-family: Arial, Helvetica, sans-serif; font-size: small; "&gt;&lt;i&gt;&lt;b&gt;U.S. Government Mortgage-Related Securities Risk &amp;#151; &lt;/b&gt;&lt;/i&gt;  There are a number of important differences among the agencies and instrumentalities of the U.S. Government that issue mortgage-related securities and among the securities that they issue. Mortgage-related securities guaranteed by Ginnie Mae are guaranteed as to the timely payment of principal and interest by Ginnie Mae and such guarantee is backed by the full faith and credit of the United States. Ginnie Mae securities also are supported by the right of Ginnie Mae to borrow funds from the U.S. Treasury to make payments under its guarantee. Mortgage-related securities issued by Fannie Mae or Freddie Mac are solely the obligations of Fannie Mae or Freddie Mac, as the case may be, and are not backed by or entitled to the full faith and credit of the United States but are supported by the right of the issuer to borrow from the Treasury.&lt;/font&gt;&lt;/li&gt;&lt;/ul&gt;&lt;ul type="square"&gt;&lt;li style="margin-left:-20px"&gt;&lt;font style="font-family: Arial, Helvetica, sans-serif; font-size: small; "&gt;&lt;i&gt;&lt;b&gt;U.S. Government Obligations Risk &amp;#151;&lt;/b&gt;&lt;/i&gt;  Certain securities in which the Fund may invest, including securities issued by certain U.S. Government agencies and U.S. Government sponsored enterprises, are not guaranteed by the U.S. Government or supported by the full faith and credit of the United States.&lt;/font&gt;&lt;/li&gt;&lt;/ul&gt;</rr:RiskNarrativeTextBlock>

In addition, many emerging securities markets have far lower trading volumes and less liquidity than developed markets.&lt;/font&gt; &lt;/li&gt;&lt;/ul&gt; &lt;ul type="square"&gt;&lt;li style="margin-left:-20px"&gt;&lt;font style="font-family: Arial, Helvetica, sans-serif; font-size: small; "&gt;&lt;strong&gt;&lt;em&gt;Equity Securities Risk&lt;/em&gt;&lt;/strong&gt; &amp;#8212; Stock markets are volatile.
