The Fund may invest in securities of both U.S. or non-U.S. issuers without &lt;/span&gt;&lt;span style="color: #000000; font-family: arial; font-size: 9.30pt;"&gt;limit, which can be U.S. dollar based or non-U.S. dollar based and may be currency hedged or unhedged. The Fund may &lt;/span&gt;&lt;span style="color: #000000; font-family: arial; font-size: 9.30pt;"&gt;invest in securities of companies of any market capitalization.&lt;/span&gt;&lt;/div&gt;  &lt;div style="margin-top: 6pt;"&gt;&lt;span style="color: #000000; font-family: arial; font-size: 9.30pt;"&gt;With respect to the Fund&#x2019;s fixed-income investments, the Fund will invest primarily using model-based asset allocation &lt;/span&gt;&lt;span style="color: #000000; font-family: arial; font-size: 9.30pt;"&gt;and security selection models. The Fund may invest in obligations issued or guaranteed by the U.S. Government, its &lt;/span&gt;&lt;span style="color: #000000; font-family: arial; font-size: 9.30pt;"&gt;agencies or instrumentalities; mortgage-backed securities issued or guaranteed by the U.S. Government or its &lt;/span&gt;&lt;span style="color: #000000; font-family: arial; font-size: 9.30pt;"&gt;agencies or instrumentalities, including U.S. agency mortgage pass-through securities; commercial mortgage-backed &lt;/span&gt;&lt;span style="color: #000000; font-family: arial; font-size: 9.30pt;"&gt;securities; mortgage to-be-announced (&#x201c;TBA&#x201d;) securities; debt obligations of U.S. issuers, including corporate bonds; &lt;/span&gt;&lt;span style="color: #000000; font-family: arial; font-size: 9.30pt;"&gt;municipal securities; asset-backed securities; and U.S.-registered dollar-denominated debt obligations of foreign &lt;/span&gt;&lt;span style="color: #000000; font-family: arial; font-size: 9.30pt;"&gt;issuers. The Fund may invest in bonds issued by companies located in countries other than the United States, &lt;/span&gt;&lt;span style="color: #000000; font-family: arial; font-size: 9.30pt;"&gt;including companies in emerging markets. These securities may have all types of interest rate payment and reset &lt;/span&gt;&lt;span style="color: #000000; font-family: arial; font-size: 9.30pt;"&gt;terms, including fixed rate, adjustable rate, floating rate, zero coupon, contingent, deferred, payment in kind and &lt;/span&gt;&lt;span style="color: #000000; font-family: arial; font-size: 9.30pt;"&gt;auction rate features. The Fund seeks to invest a substantial portion of its assets in U.S.-registered, dollar-denominated&lt;/span&gt;&lt;span style="color: #000000; font-family: arial; font-size: 9.30pt;"&gt; bonds. The Fund may invest up to 10% of its assets in securities rated below investment grade (&#x201c;high &lt;/span&gt;&lt;span style="color: #000000; font-family: arial; font-size: 9.30pt;"&gt;yield&#x201d; or &#x201c;junk&#x201d; bonds). The Fund may invest in bonds of any maturity or duration.&lt;/span&gt;&lt;/div&gt;  &lt;div style="margin-top: 6pt;"&gt;&lt;span style="color: #000000; font-family: arial; font-size: 9.30pt;"&gt;The Fund may invest a significant portion of its fixed income holdings in U.S. agency mortgage pass-through securities, &lt;/span&gt;&lt;span style="color: #000000; font-family: arial; font-size: 9.30pt;"&gt;which are securities issued by entities such as the Government National Mortgage Association (&#x201c;GNMA&#x201d;) and the &lt;/span&gt;&lt;/div&gt;  &lt;div style="line-height: 10.695pt; text-align: left;"&gt;&lt;span style="color: #000000; font-family: arial; font-size: 9.30pt;"&gt;Federal National Mortgage Association that are backed by pools of mortgages. Most transactions in mortgage pass-through&lt;/span&gt;&lt;span style="color: #000000; font-family: arial; font-size: 9.30pt;"&gt; securities occur through standardized contracts for future delivery in which the exact mortgage-backed &lt;/span&gt;&lt;span style="color: #000000; font-family: arial; font-size: 9.30pt;"&gt;securities to be delivered are not specified until a few days prior to settlement. The Fund expects to enter into such &lt;/span&gt;&lt;span style="color: #000000; font-family: arial; font-size: 9.30pt;"&gt;contracts on a regular basis.&lt;/span&gt;&lt;span style="color: #000000; font-family: arial; font-size: 9.30pt; line-height: 10.695pt;"&gt; &lt;/span&gt;&lt;/div&gt;  &lt;div style="margin-top: 6pt;"&gt;&lt;span style="color: #000000; font-family: arial; font-size: 9.30pt;"&gt;The Fund may use derivatives, including options, futures, swaps (including, but not limited to, total return swaps), &lt;/span&gt;&lt;span style="color: #000000; font-family: arial; font-size: 9.30pt;"&gt;forward contracts and various other instruments, both to seek to increase the return of the Fund and to hedge (or &lt;/span&gt;&lt;span style="color: #000000; font-family: arial; font-size: 9.30pt;"&gt;protect) the value of its assets against adverse movements in currency exchange rates, interest rates and movements &lt;/span&gt;&lt;span style="color: #000000; font-family: arial; font-size: 9.30pt;"&gt;in the securities markets. The Fund may also invest in indexed and inverse securities.&lt;/span&gt;&lt;/div&gt; </oef:StrategyNarrativeTextBlock>

Changes in an issuer&#x2019;s credit rating or the market&#x2019;s &lt;/span&gt;&lt;span style="color: #000000; font-family: arial; font-size: 9.30pt;"&gt;perception of an issuer&#x2019;s creditworthiness may also affect the value of the Fund&#x2019;s investment in that issuer. The &lt;/span&gt;&lt;span style="color: #000000; font-family: arial; font-size: 9.30pt;"&gt;degree of credit risk depends on both the financial condition of the issuer and the terms of the obligation.&lt;/span&gt;&lt;/div&gt;  &lt;div style="margin-top: 4pt;"&gt;&lt;span style="color: #000000; font-family: arial; font-size: 9.30pt; font-style: italic;"&gt;Interest Rate Risk&lt;/span&gt;&lt;span style="color: #000000; font-family: arial; font-size: 9.30pt;"&gt; &#x2014; The market value of bonds and other fixed-income securities changes in response to interest &lt;/span&gt;&lt;span style="color: #000000; font-family: arial; font-size: 9.30pt;"&gt;rate changes and other factors. Interest rate risk is the risk that prices of bonds and other fixed-income securities &lt;/span&gt;&lt;span style="color: #000000; font-family: arial; font-size: 9.30pt;"&gt;will increase as interest rates fall and decrease as interest rates rise.&lt;/span&gt;&lt;span style="color: #000000; font-family: arial; font-size: 9.30pt; line-height: 10.695pt;"&gt; &lt;/span&gt;&lt;/div&gt;  &lt;div style="margin-top: 4pt;"&gt;&lt;span style="color: #000000; font-family: arial; font-size: 9.30pt;"&gt;The Fund may be subject to a greater risk of rising interest rates during a period of low interest rates. For example, &lt;/span&gt;&lt;span style="color: #000000; font-family: arial; font-size: 9.30pt;"&gt;if interest rates increase by 1%, assuming a current portfolio duration of ten years, and all other factors being &lt;/span&gt;&lt;span style="color: #000000; font-family: arial; font-size: 9.30pt;"&gt;equal, the value of the Fund&#x2019;s investments would be expected to decrease by 10%. (Duration is a measure of the &lt;/span&gt;&lt;span style="color: #000000; font-family: arial; font-size: 9.30pt;"&gt;price sensitivity of a debt security or portfolio of debt securities to relative changes in interest rates.) The magnitude &lt;/span&gt;&lt;span style="color: #000000; font-family: arial; font-size: 9.30pt;"&gt;of these fluctuations in the market price of bonds and other fixed-income securities is generally greater for those &lt;/span&gt;&lt;span style="color: #000000; font-family: arial; font-size: 9.30pt;"&gt;securities with longer maturities. Fluctuations in the market price of the Fund&#x2019;s investments will not affect interest &lt;/span&gt;&lt;span style="color: #000000; font-family: arial; font-size: 9.30pt;"&gt;income derived from instruments already owned by the Fund, but will be reflected in the Fund&#x2019;s net asset value. The &lt;/span&gt;&lt;span style="color: #000000; font-family: arial; font-size: 9.30pt;"&gt;Fund may lose money if short-term or long-term interest rates rise sharply in a manner not anticipated by Fund &lt;/span&gt;&lt;span style="color: #000000; font-family: arial; font-size: 9.30pt;"&gt;management.&lt;/span&gt;&lt;span style="color: #000000; font-family: arial; font-size: 9.30pt; line-height: 10.695pt;"&gt; &lt;/span&gt;&lt;/div&gt;  &lt;div style="margin-top: 4pt;"&gt;&lt;span style="color: #000000; font-family: arial; font-size: 9.30pt;"&gt;To the extent the Fund invests in debt securities that may be prepaid at the option of the obligor (such as mortgage-backed&lt;/span&gt;&lt;span style="color: #000000; font-family: arial; font-size: 9.30pt;"&gt; securities), the sensitivity of such securities to changes in interest rates may increase (to the detriment of &lt;/span&gt;&lt;span style="color: #000000; font-family: arial; font-size: 9.30pt;"&gt;the Fund) when interest rates rise. Moreover, because rates on certain floating rate debt securities typically reset &lt;/span&gt;&lt;span style="color: #000000; font-family: arial; font-size: 9.30pt;"&gt;only periodically, changes in prevailing interest rates (and particularly sudden and significant changes) can be &lt;/span&gt;&lt;span style="color: #000000; font-family: arial; font-size: 9.30pt;"&gt;expected to cause some fluctuations in the net asset value of the Fund to the extent that it invests in floating rate &lt;/span&gt;&lt;span style="color: #000000; font-family: arial; font-size: 9.30pt;"&gt;debt securities.&lt;/span&gt;&lt;span style="color: #000000; font-family: arial; font-size: 9.30pt; line-height: 10.695pt;"&gt; &lt;/span&gt;&lt;/div&gt;  &lt;div style="margin-top: 4pt;"&gt;&lt;span style="color: #000000; font-family: arial; font-size: 9.30pt;"&gt;These basic principles of bond prices also apply to U.S. Government securities. A security backed by the &#x201c;full faith &lt;/span&gt;&lt;span style="color: #000000; font-family: arial; font-size: 9.30pt;"&gt;and credit&#x201d; of the U.S. Government is guaranteed only as to its stated interest rate and face value at maturity, not &lt;/span&gt;&lt;span style="color: #000000; font-family: arial; font-size: 9.30pt;"&gt;its current market price. Just like other fixed-income securities, government-guaranteed securities will fluctuate in &lt;/span&gt;&lt;span style="color: #000000; font-family: arial; font-size: 9.30pt;"&gt;value when interest rates change.&lt;/span&gt;&lt;/div&gt;  &lt;div style="margin-top: 4pt;"&gt;&lt;span style="color: #000000; font-family: arial; font-size: 9.30pt;"&gt;A general rise in interest rates has the potential to cause investors to move out of fixed-income securities on a large &lt;/span&gt;&lt;span style="color: #000000; font-family: arial; font-size: 9.30pt;"&gt;scale, which may increase redemptions from funds that hold large amounts of fixed-income securities. Heavy &lt;/span&gt;&lt;span style="color: #000000; font-family: arial; font-size: 9.30pt;"&gt;redemptions could cause the Fund to sell assets at inopportune times or at a loss or depressed value and could &lt;/span&gt;&lt;span style="color: #000000; font-family: arial; font-size: 9.30pt;"&gt;hurt the Fund&#x2019;s performance.&lt;/span&gt;&lt;span style="color: #000000; font-family: arial; font-size: 9.30pt; line-height: 10.695pt;"&gt; &lt;/span&gt;&lt;/div&gt;  &lt;div style="margin-top: 4pt;"&gt;&lt;span style="color: #000000; font-family: arial; font-size: 9.30pt; font-style: italic;"&gt;Extension Risk&lt;/span&gt;&lt;span style="color: #000000; font-family: arial; font-size: 9.30pt;"&gt; &#x2014; When interest rates rise, certain obligations will be paid off by the obligor more slowly than &lt;/span&gt;&lt;span style="color: #000000; font-family: arial; font-size: 9.30pt;"&gt;anticipated, causing the value of these obligations to fall.&lt;/span&gt;&lt;span style="color: #000000; font-family: arial; font-size: 9.30pt; line-height: 10.695pt;"&gt; &lt;/span&gt;&lt;/div&gt;  &lt;div style="margin-top: 4pt;"&gt;&lt;span style="color: #000000; font-family: arial; font-size: 9.30pt; font-style: italic;"&gt;Prepayment Risk&lt;/span&gt;&lt;span style="color: #000000; font-family: arial; font-size: 9.30pt;"&gt; &#x2014; When interest rates fall, certain obligations will be paid off by the obligor more quickly than &lt;/span&gt;&lt;span style="color: #000000; font-family: arial; font-size: 9.30pt;"&gt;originally anticipated, and the Fund may have to invest the proceeds in securities with lower yields.&lt;/span&gt;&lt;span style="color: #000000; font-family: arial; font-size: 9.30pt; line-height: 10.695pt;"&gt; &lt;/span&gt;&lt;/div&gt; </oef:RiskTextBlock>

The &lt;/span&gt;&lt;span style="color: #000000; font-family: arial; font-size: 9.30pt;"&gt;Fund is permitted to invest in a class of structured securities that is either subordinated or unsubordinated to the &lt;/span&gt;&lt;span style="color: #000000; font-family: arial; font-size: 9.30pt;"&gt;right of payment of another class. Subordinated structured securities typically have higher yields and present &lt;/span&gt;&lt;span style="color: #000000; font-family: arial; font-size: 9.30pt;"&gt;greater risks than unsubordinated structured securities. Structured securities are typically sold in private placement &lt;/span&gt;&lt;span style="color: #000000; font-family: arial; font-size: 9.30pt;"&gt;transactions, and there currently is no active trading market for structured securities. Structured securities are &lt;/span&gt;&lt;span style="color: #000000; font-family: arial; font-size: 9.30pt;"&gt;based upon the movement of one or more factors, including currency exchange rates, interest rates, reference &lt;/span&gt;&lt;span style="color: #000000; font-family: arial; font-size: 9.30pt;"&gt;bonds and stock indices, and changes in interest rates and impact of these factors may cause significant price &lt;/span&gt;&lt;span style="color: #000000; font-family: arial; font-size: 9.30pt;"&gt;fluctuations. Additionally, changes in the reference instrument or security may cause the interest rate on the &lt;/span&gt;&lt;span style="color: #000000; font-family: arial; font-size: 9.30pt;"&gt;structured security to be reduced to zero. Certain issuers of such structured securities may be deemed to be &lt;/span&gt;&lt;span style="color: #000000; font-family: arial; font-size: 9.30pt;"&gt;&#x201c;investment companies&#x201d; as defined in the Investment Company Act. As a result, the Fund&#x2019;s investment in such &lt;/span&gt;&lt;span style="color: #000000; font-family: arial; font-size: 9.30pt;"&gt;securities may be limited by certain investment restrictions contained in the Investment Company Act.&lt;/span&gt;&lt;span style="color: #000000; font-family: arial; font-size: 9.30pt; line-height: 10.695pt;"&gt; &lt;/span&gt;&lt;/div&gt; &lt;/div&gt; &lt;div style="clear: both; position: relative;"&gt; &lt;/div&gt; &lt;/div&gt; </oef:RiskTextBlock>

The Fund intends to invest at least 25% of its assets in equity securities and at least &lt;/span&gt;&lt;span style="color: #000000; font-family: arial; font-size: 9.30pt;"&gt;25% of its assets in senior fixed income securities, such as U.S. government debt securities, corporate debt &lt;/span&gt;&lt;span style="color: #000000; font-family: arial; font-size: 9.30pt;"&gt;securities, and mortgage-backed and asset-backed securities.&lt;/span&gt;&lt;/div&gt;  &lt;div style="margin-top: 6pt;"&gt;&lt;span style="color: #000000; font-family: arial; font-size: 9.30pt;"&gt;With respect to the Fund&#x2019;s equity investments, the Fund primarily intends to invest in equity securities or other &lt;/span&gt;&lt;span style="color: #000000; font-family: arial; font-size: 9.30pt;"&gt;financial instruments that are components of, or have characteristics similar to, the securities included in the MSCI All &lt;/span&gt;&lt;span style="color: #000000; font-family: arial; font-size: 9.30pt;"&gt;Country World Index (the &#x201c;ACWI&#x201d;). The ACWI is a capitalization-weighted index from a broad range of industries chosen &lt;/span&gt;&lt;span style="color: #000000; font-family: arial; font-size: 9.30pt;"&gt;for market size, liquidity and industry group representation. In selecting equity investments, the Fund primarily uses &lt;/span&gt;&lt;span style="color: #000000; font-family: arial; font-size: 9.30pt;"&gt;proprietary return forecast models that incorporate quantitative analysis. Equity securities include common stock and &lt;/span&gt;&lt;span style="color: #000000; font-family: arial; font-size: 9.30pt;"&gt;preferred stock. The Fund primarily seeks to buy common stock and may also invest in preferred stock. From time to &lt;/span&gt;&lt;span style="color: #000000; font-family: arial; font-size: 9.30pt;"&gt;time, the Fund may invest in shares of companies through &#x201c;new issues&#x201d; or initial public offerings (&#x201c;IPOs&#x201d;). The Fund &lt;/span&gt;&lt;span style="color: #000000; font-family: arial; font-size: 9.30pt;"&gt;may also purchase convertible securities. The Fund may invest in securities of both U.S. or non-U.S. issuers without &lt;/span&gt;&lt;span style="color: #000000; font-family: arial; font-size: 9.30pt;"&gt;limit, which can be U.S. dollar based or non-U.S. dollar based and may be currency hedged or unhedged. The Fund may &lt;/span&gt;&lt;span style="color: #000000; font-family: arial; font-size: 9.30pt;"&gt;invest in securities of companies of any market capitalization.&lt;/span&gt;&lt;/div&gt;  &lt;div style="margin-top: 6pt;"&gt;&lt;span style="color: #000000; font-family: arial; font-size: 9.30pt;"&gt;With respect to the Fund&#x2019;s fixed-income investments, the Fund will invest primarily using model-based asset allocation &lt;/span&gt;&lt;span style="color: #000000; font-family: arial; font-size: 9.30pt;"&gt;and security selection models. The Fund may invest in obligations issued or guaranteed by the U.S. Government, its &lt;/span&gt;&lt;span style="color: #000000; font-family: arial; font-size: 9.30pt;"&gt;agencies or instrumentalities; mortgage-backed securities issued or guaranteed by the U.S. Government or its &lt;/span&gt;&lt;span style="color: #000000; font-family: arial; font-size: 9.30pt;"&gt;agencies or instrumentalities, including U.S. agency mortgage pass-through securities; commercial mortgage-backed &lt;/span&gt;&lt;span style="color: #000000; font-family: arial; font-size: 9.30pt;"&gt;securities; mortgage to-be-announced (&#x201c;TBA&#x201d;) securities; debt obligations of U.S. issuers, including corporate bonds; &lt;/span&gt;&lt;span style="color: #000000; font-family: arial; font-size: 9.30pt;"&gt;municipal securities; asset-backed securities; and U.S.-registered dollar-denominated debt obligations of foreign &lt;/span&gt;&lt;span style="color: #000000; font-family: arial; font-size: 9.30pt;"&gt;issuers. The Fund may invest in bonds issued by companies located in countries other than the United States, &lt;/span&gt;&lt;span style="color: #000000; font-family: arial; font-size: 9.30pt;"&gt;including companies in emerging markets. These securities may have all types of interest rate payment and reset &lt;/span&gt;&lt;span style="color: #000000; font-family: arial; font-size: 9.30pt;"&gt;terms, including fixed rate, adjustable rate, floating rate, zero coupon, contingent, deferred, payment in kind and &lt;/span&gt;&lt;span style="color: #000000; font-family: arial; font-size: 9.30pt;"&gt;auction rate features.

The Fund may invest up to 10% of its assets in securities rated below investment grade (&#x201c;high &lt;/span&gt;&lt;span style="color: #000000; font-family: arial; font-size: 9.30pt;"&gt;yield&#x201d; or &#x201c;junk&#x201d; bonds). The Fund may invest in bonds of any maturity or duration.&lt;/span&gt;&lt;/div&gt;  &lt;div style="margin-top: 6pt;"&gt;&lt;span style="color: #000000; font-family: arial; font-size: 9.30pt;"&gt;The Fund may invest a significant portion of its fixed income holdings in U.S. agency mortgage pass-through securities, &lt;/span&gt;&lt;span style="color: #000000; font-family: arial; font-size: 9.30pt;"&gt;which are securities issued by entities such as the Government National Mortgage Association (&#x201c;GNMA&#x201d;) and the &lt;/span&gt;&lt;span style="color: #000000; font-family: arial; font-size: 9.30pt;"&gt;Federal National Mortgage Association that are backed by pools of mortgages. Most transactions in mortgage pass-through&lt;/span&gt;&lt;span style="color: #000000; font-family: arial; font-size: 9.30pt;"&gt; securities occur through standardized contracts for future delivery in which the exact mortgage-backed &lt;/span&gt;&lt;span style="color: #000000; font-family: arial; font-size: 9.30pt;"&gt;securities to be delivered are not specified until a few days prior to settlement. The Fund expects to enter into such &lt;/span&gt;&lt;span style="color: #000000; font-family: arial; font-size: 9.30pt;"&gt;contracts on a regular basis.&lt;/span&gt;&lt;span style="color: #000000; font-family: arial; font-size: 9.30pt; line-height: 10.695pt;"&gt; &lt;/span&gt;&lt;/div&gt;  &lt;div style="margin-top: 6pt;"&gt;&lt;span style="color: #000000; font-family: arial; font-size: 9.30pt;"&gt;The Fund may use derivatives, including options, futures, swaps (including, but not limited to, total return swaps), &lt;/span&gt;&lt;span style="color: #000000; font-family: arial; font-size: 9.30pt;"&gt;forward contracts and various other instruments, both to seek to increase the return of the Fund and to hedge (or &lt;/span&gt;&lt;span style="color: #000000; font-family: arial; font-size: 9.30pt;"&gt;protect) the value of its assets against adverse movements in currency exchange rates, interest rates and movements &lt;/span&gt;&lt;span style="color: #000000; font-family: arial; font-size: 9.30pt;"&gt;in the securities markets.

Changes in an issuer&#x2019;s credit rating or the market&#x2019;s &lt;/span&gt;&lt;span style="color: #000000; font-family: arial; font-size: 9.30pt;"&gt;perception of an issuer&#x2019;s creditworthiness may also affect the value of the Fund&#x2019;s investment in that issuer. The &lt;/span&gt;&lt;span style="color: #000000; font-family: arial; font-size: 9.30pt;"&gt;degree of credit risk depends on both the financial condition of the issuer and the terms of the obligation.&lt;/span&gt;&lt;/div&gt;  &lt;div style="line-height: 10.695pt; margin-left: 12pt; text-align: left;"&gt;&lt;span style="color: #000000; font-family: arial; font-size: 9.30pt; font-style: italic;"&gt;Interest Rate Risk&lt;/span&gt;&lt;span style="color: #000000; font-family: arial; font-size: 9.30pt;"&gt; &#x2014; The market value of bonds and other fixed-income securities changes in response to interest &lt;/span&gt;&lt;span style="color: #000000; font-family: arial; font-size: 9.30pt;"&gt;rate changes and other factors. Interest rate risk is the risk that prices of bonds and other fixed-income securities &lt;/span&gt;&lt;span style="color: #000000; font-family: arial; font-size: 9.30pt;"&gt;will increase as interest rates fall and decrease as interest rates rise.&lt;/span&gt;&lt;span style="color: #000000; font-family: arial; font-size: 9.30pt; line-height: 10.695pt;"&gt; &lt;/span&gt;&lt;/div&gt;  &lt;div style="margin-top: 4pt;"&gt;&lt;span style="color: #000000; font-family: arial; font-size: 9.30pt;"&gt;The Fund may be subject to a greater risk of rising interest rates during a period of low interest rates. For example, &lt;/span&gt;&lt;span style="color: #000000; font-family: arial; font-size: 9.30pt;"&gt;if interest rates increase by 1%, assuming a current portfolio duration of ten years, and all other factors being &lt;/span&gt;&lt;span style="color: #000000; font-family: arial; font-size: 9.30pt;"&gt;equal, the value of the Fund&#x2019;s investments would be expected to decrease by 10%. (Duration is a measure of the &lt;/span&gt;&lt;span style="color: #000000; font-family: arial; font-size: 9.30pt;"&gt;price sensitivity of a debt security or portfolio of debt securities to relative changes in interest rates.) The magnitude &lt;/span&gt;&lt;span style="color: #000000; font-family: arial; font-size: 9.30pt;"&gt;of these fluctuations in the market price of bonds and other fixed-income securities is generally greater for those &lt;/span&gt;&lt;span style="color: #000000; font-family: arial; font-size: 9.30pt;"&gt;securities with longer maturities. Fluctuations in the market price of the Fund&#x2019;s investments will not affect interest &lt;/span&gt;&lt;span style="color: #000000; font-family: arial; font-size: 9.30pt;"&gt;income derived from instruments already owned by the Fund, but will be reflected in the Fund&#x2019;s net asset value. The &lt;/span&gt;&lt;span style="color: #000000; font-family: arial; font-size: 9.30pt;"&gt;Fund may lose money if short-term or long-term interest rates rise sharply in a manner not anticipated by Fund &lt;/span&gt;&lt;span style="color: #000000; font-family: arial; font-size: 9.30pt;"&gt;management.&lt;/span&gt;&lt;span style="color: #000000; font-family: arial; font-size: 9.30pt; line-height: 10.695pt;"&gt; &lt;/span&gt;&lt;/div&gt;  &lt;div style="margin-top: 4pt;"&gt;&lt;span style="color: #000000; font-family: arial; font-size: 9.30pt;"&gt;To the extent the Fund invests in debt securities that may be prepaid at the option of the obligor (such as mortgage-backed&lt;/span&gt;&lt;span style="color: #000000; font-family: arial; font-size: 9.30pt;"&gt; securities), the sensitivity of such securities to changes in interest rates may increase (to the detriment of &lt;/span&gt;&lt;span style="color: #000000; font-family: arial; font-size: 9.30pt;"&gt;the Fund) when interest rates rise. Moreover, because rates on certain floating rate debt securities typically reset &lt;/span&gt;&lt;span style="color: #000000; font-family: arial; font-size: 9.30pt;"&gt;only periodically, changes in prevailing interest rates (and particularly sudden and significant changes) can be &lt;/span&gt;&lt;span style="color: #000000; font-family: arial; font-size: 9.30pt;"&gt;expected to cause some fluctuations in the net asset value of the Fund to the extent that it invests in floating rate &lt;/span&gt;&lt;span style="color: #000000; font-family: arial; font-size: 9.30pt;"&gt;debt securities.&lt;/span&gt;&lt;span style="color: #000000; font-family: arial; font-size: 9.30pt; line-height: 10.695pt;"&gt; &lt;/span&gt;&lt;/div&gt;  &lt;div style="margin-top: 4pt;"&gt;&lt;span style="color: #000000; font-family: arial; font-size: 9.30pt;"&gt;These basic principles of bond prices also apply to U.S. Government securities. A security backed by the &#x201c;full faith &lt;/span&gt;&lt;span style="color: #000000; font-family: arial; font-size: 9.30pt;"&gt;and credit&#x201d; of the U.S. Government is guaranteed only as to its stated interest rate and face value at maturity, not &lt;/span&gt;&lt;span style="color: #000000; font-family: arial; font-size: 9.30pt;"&gt;its current market price. Just like other fixed-income securities, government-guaranteed securities will fluctuate in &lt;/span&gt;&lt;span style="color: #000000; font-family: arial; font-size: 9.30pt;"&gt;value when interest rates change.&lt;/span&gt;&lt;/div&gt;  &lt;div style="margin-top: 4pt;"&gt;&lt;span style="color: #000000; font-family: arial; font-size: 9.30pt;"&gt;A general rise in interest rates has the potential to cause investors to move out of fixed-income securities on a large &lt;/span&gt;&lt;span style="color: #000000; font-family: arial; font-size: 9.30pt;"&gt;scale, which may increase redemptions from funds that hold large amounts of fixed-income securities. Heavy &lt;/span&gt;&lt;span style="color: #000000; font-family: arial; font-size: 9.30pt;"&gt;redemptions could cause the Fund to sell assets at inopportune times or at a loss or depressed value and could &lt;/span&gt;&lt;span style="color: #000000; font-family: arial; font-size: 9.30pt;"&gt;hurt the Fund&#x2019;s performance.&lt;/span&gt;&lt;span style="color: #000000; font-family: arial; font-size: 9.30pt; line-height: 10.695pt;"&gt; &lt;/span&gt;&lt;/div&gt;  &lt;div style="margin-top: 4pt;"&gt;&lt;span style="color: #000000; font-family: arial; font-size: 9.30pt; font-style: italic;"&gt;Extension Risk&lt;/span&gt;&lt;span style="color: #000000; font-family: arial; font-size: 9.30pt;"&gt; &#x2014; When interest rates rise, certain obligations will be paid off by the obligor more slowly than &lt;/span&gt;&lt;span style="color: #000000; font-family: arial; font-size: 9.30pt;"&gt;anticipated, causing the value of these obligations to fall.&lt;/span&gt;&lt;span style="color: #000000; font-family: arial; font-size: 9.30pt; line-height: 10.695pt;"&gt; &lt;/span&gt;&lt;/div&gt;  &lt;div style="margin-top: 4pt;"&gt;&lt;span style="color: #000000; font-family: arial; font-size: 9.30pt; font-style: italic;"&gt;Prepayment Risk&lt;/span&gt;&lt;span style="color: #000000; font-family: arial; font-size: 9.30pt;"&gt; &#x2014; When interest rates fall, certain obligations will be paid off by the obligor more quickly than &lt;/span&gt;&lt;span style="color: #000000; font-family: arial; font-size: 9.30pt;"&gt;originally anticipated, and the Fund may have to invest the proceeds in securities with lower yields.&lt;/span&gt;&lt;span style="color: #000000; font-family: arial; font-size: 9.30pt; line-height: 10.695pt;"&gt; &lt;/span&gt;&lt;/div&gt; </oef:RiskTextBlock>

The value of &lt;/span&gt;&lt;span style="color: #000000; font-family: arial; font-size: 9.30pt;"&gt;a security or other asset may decline due to changes in general market conditions, economic trends or events that &lt;/span&gt;&lt;span style="color: #000000; font-family: arial; font-size: 9.30pt;"&gt;are not specifically related to the issuer of the security or other asset, or factors that affect a particular issuer or &lt;/span&gt;&lt;span style="color: #000000; font-family: arial; font-size: 9.30pt;"&gt;issuers, exchange, country, group of countries, region, market, industry, group of industries, sector or asset class. &lt;/span&gt;&lt;span style="color: #000000; font-family: arial; font-size: 9.30pt;"&gt;The success of the Fund&#x2019;s activities could be affected by interest rates, availability of credit, inflation rates, &lt;/span&gt;&lt;span style="color: #000000; font-family: arial; font-size: 9.30pt;"&gt;economic uncertainty, changes in laws, tariffs and trade barriers, supply chain disruptions, economic sanctions, &lt;/span&gt;&lt;span style="color: #000000; font-family: arial; font-size: 9.30pt;"&gt;currency exchange controls, and local, regional or global events such as war, acts of terrorism, natural and &lt;/span&gt;&lt;span style="color: #000000; font-family: arial; font-size: 9.30pt;"&gt;environmental disasters, the spread of infectious illness or other public health issues, recessions, or other events. &lt;/span&gt;&lt;span style="color: #000000; font-family: arial; font-size: 9.30pt;"&gt;The Fund seeks to pursue its investment objective by using proprietary models that incorporate quantitative analysis &lt;/span&gt;&lt;span style="color: #000000; font-family: arial; font-size: 9.30pt;"&gt;and is subject to &#x201c;Model Risk&#x201d; as described below.&lt;/span&gt;&lt;span style="color: #000000; font-family: arial; font-size: 9.30pt; line-height: 10.695pt;"&gt; &lt;/span&gt;&lt;/div&gt; &lt;/div&gt; &lt;div style="clear: both; position: relative;"&gt; &lt;/div&gt; &lt;/div&gt;  &lt;div style="margin-top: 4pt;"&gt;&lt;span style="color: #000000; font-family: arial; font-size: 9.30pt;"&gt;Recent policy initiatives undertaken by the U.S. government have the potential to impact international relations, &lt;/span&gt;&lt;span style="color: #000000; font-family: arial; font-size: 9.30pt;"&gt;trade agreements and the overall regulatory environment in ways that could create uncertainty and instability in &lt;/span&gt;&lt;span style="color: #000000; font-family: arial; font-size: 9.30pt;"&gt;domestic and global markets, and could adversely affect the investment performance of the Fund. In particular, &lt;/span&gt;&lt;span style="color: #000000; font-family: arial; font-size: 9.30pt;"&gt;actions taken by the U.S. government in respect of international trade relations could lead to trade wars, increased &lt;/span&gt;&lt;span style="color: #000000; font-family: arial; font-size: 9.30pt;"&gt;costs for imported goods, disruptions in supply chains, reduced foreign investment, and instability in regions where &lt;/span&gt;&lt;span style="color: #000000; font-family: arial; font-size: 9.30pt;"&gt;the Fund invests.&lt;/span&gt;&lt;/div&gt; </oef:RiskTextBlock>

In addition, a company&#x2019;s &lt;/span&gt;&lt;span style="color: #000000; font-family: arial; font-size: 9.30pt;"&gt;preferred securities generally pay dividends only after the company makes required payments to holders of its &lt;/span&gt;&lt;span style="color: #000000; font-family: arial; font-size: 9.30pt;"&gt;bonds and other debt. For this reason, the value of preferred securities will usually react more strongly than bonds &lt;/span&gt;&lt;span style="color: #000000; font-family: arial; font-size: 9.30pt;"&gt;and other debt to actual or perceived changes in the company&#x2019;s financial condition or prospects.

The Fund may have the right to receive &lt;/span&gt;&lt;span style="color: #000000; font-family: arial; font-size: 9.30pt;"&gt;payments only from the structured security, and generally does not have direct rights against the issuer or the entity &lt;/span&gt;&lt;span style="color: #000000; font-family: arial; font-size: 9.30pt;"&gt;that sold the assets to be securitized. In addition to the general risks associated with debt securities discussed &lt;/span&gt;&lt;span style="color: #000000; font-family: arial; font-size: 9.30pt;"&gt;herein, structured securities carry additional risks, including, but not limited to: the possibility that distributions &lt;/span&gt;&lt;span style="color: #000000; font-family: arial; font-size: 9.30pt;"&gt;from collateral securities will not be adequate to make interest or other payments; the quality of the collateral may &lt;/span&gt;&lt;span style="color: #000000; font-family: arial; font-size: 9.30pt;"&gt;decline in value or default; and the possibility that the structured securities are subordinate to other classes. The &lt;/span&gt;&lt;span style="color: #000000; font-family: arial; font-size: 9.30pt;"&gt;Fund is permitted to invest in a class of structured securities that is either subordinated or unsubordinated to the &lt;/span&gt;&lt;span style="color: #000000; font-family: arial; font-size: 9.30pt;"&gt;right of payment of another class. Subordinated structured securities typically have higher yields and present &lt;/span&gt;&lt;span style="color: #000000; font-family: arial; font-size: 9.30pt;"&gt;greater risks than unsubordinated structured securities. Structured securities are typically sold in private placement &lt;/span&gt;&lt;span style="color: #000000; font-family: arial; font-size: 9.30pt;"&gt;transactions, and there currently is no active trading market for structured securities. Structured securities are &lt;/span&gt;&lt;span style="color: #000000; font-family: arial; font-size: 9.30pt;"&gt;based upon the movement of one or more factors, including currency exchange rates, interest rates, reference &lt;/span&gt;&lt;span style="color: #000000; font-family: arial; font-size: 9.30pt;"&gt;bonds and stock indices, and changes in interest rates and impact of these factors may cause significant price &lt;/span&gt;&lt;span style="color: #000000; font-family: arial; font-size: 9.30pt;"&gt;fluctuations. Additionally, changes in the reference instrument or security may cause the interest rate on the &lt;/span&gt;&lt;span style="color: #000000; font-family: arial; font-size: 9.30pt;"&gt;structured security to be reduced to zero. Certain issuers of such structured securities may be deemed to be &lt;/span&gt;&lt;span style="color: #000000; font-family: arial; font-size: 9.30pt;"&gt;&#x201c;investment companies&#x201d; as defined in the Investment Company Act.

Such indices use withholding tax rates that are often at a higher rate than the rates to which the Fund is subject in each country, including for countries where the Fund is not subject to withholding taxes. When this is the case, index performance will be lower than if the index used the Fund&#x2019;s applicable withholding tax rates, if any.
