The Fund seeks to achieve its investment objective by investing in both equity and fixed-income securities, including money market securities and other short-term securities or instruments that the Fund management team believes may offer attractive risk-adjusted returns. Equity securities include common stock, preferred stock, American Depository Receipts, or securities or other instruments whose price is linked to the value of common stock. The combination of equity securities will be varied from time to time both with respect to types of securities and markets in response to changing market and economic trends. The Fund may also purchase convertible securities. The Fund may invest in the securities of companies of any market capitalization. The Fund may also invest in Real Estate Investment Trusts. &lt;/div&gt;&lt;div style="margin-top:12pt;margin-bottom:0pt;font-size:10pt;font-family:arial;"&gt;The Fund seeks to provide risk-adjusted total return while managing volatility levels by using a systematic, quantitative model-based approach. Generally, the Fund seeks diversification across markets, industries and issuers as one of its strategies to reduce volatility. Fund management may consider a variety of factors, such as, without limitation, valuation, the relative opportunity for capital appreciation, quality and sentiment. &lt;/div&gt;&lt;div style="margin-top:12pt;margin-bottom:0pt;font-size:10pt;font-family:arial;"&gt;The Fund may invest in developed and emerging markets, including frontier markets. This flexibility allows Fund management to look for investments in &lt;/div&gt;&lt;div style="margin-top:0pt;margin-bottom:0pt;font-size:10pt;font-family:arial;"&gt; markets around the world that it believes will provide the best relative asset allocation to meet the Fund&#x2019;s objective. In pursuing its investment objective, the Fund may utilize short positions. The Fund expects to implement short positions through short sales of any instrument that the Fund may purchase for investment or by using options, swaps, futures, forwards, contracts for difference or other derivative instruments. &lt;/div&gt;&lt;div style="margin-top:12pt;margin-bottom:0pt;font-size:10pt;font-family:arial;"&gt;With respect to the Fund&#x2019;s fixed-income investments, the Fund may invest in all types of debt securities, including, but not limited to, U.S. and foreign government bonds, corporate bonds and convertible bonds, structured notes, credit-linked notes, loan assignments and participations, mortgage- and asset-backed securities, inflation-linked bonds, and securities issued or guaranteed by certain international organizations such as the World Bank. The Fund may invest in &#x201c;junk&#x201d; bonds, corporate loans, bank loans and distressed securities. These securities offer the possibility of relatively higher returns but are significantly riskier than higher rated debt securities. The Fund may invest in debt securities of any maturity or duration. &lt;/div&gt;&lt;div style="margin-top:12pt;margin-bottom:0pt;font-size:10pt;font-family:arial;"&gt;The Fund may use derivatives, including options, futures, credit default swaps, swaps (including, but not limited to, total return swaps that may be referred to as contracts for difference) and forward contracts both to seek to increase the return of the Fund and to hedge (or protect) the value of its assets against adverse movements in currency exchange rates, interest rates and movements in the securities markets. Derivatives are financial instruments whose value is derived from another security, a commodity, a currency or an index. The Fund has the ability to use forward currency contracts and other currency derivatives. From time to time, the Fund may own foreign cash equivalents or foreign bank deposits as part of the Fund&#x2019;s investment strategy. The Fund may also invest in non&#x2011;U.S. currencies, however, the Fund may underweight or overweight a currency based on the Fund management team&#x2019;s outlook. The Fund may invest in indexed and inverse securities. &lt;/div&gt;&lt;div style="margin-top:12pt;margin-bottom:0pt;font-size:10pt;font-family:arial;"&gt;The Fund may invest a portion of its assets in securities related to real assets (like real estate- or precious metals-related securities) such as stock, bonds or convertible bonds issued by real estate investment trusts or companies that mine precious metals.

Borrowers generally pay interest on corporate loans at rates that change in response to changes in market interest rates such as the Secured Overnight Financing Rate (&#x201c;SOFR&#x201d;) 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 and wide bid/ask spreads. In addition, transactions in corporate loans may settle on a delayed basis. As a result, the proceeds from the sale of corporate loans may not be readily available to make additional investments or to meet the Fund&#x2019;s redemption obligations. To the extent the extended settlement process gives rise to short-term liquidity needs, the Fund may hold additional cash, sell investments or temporarily borrow from banks and other lenders. &lt;/div&gt;</oef:RiskTextBlock>

Changes in an issuer&#x2019;s credit rating or the market&#x2019;s perception of an issuer&#x2019;s creditworthiness may also affect the value of the Fund&#x2019;s investment in that issuer. The degree of credit risk depends on both the financial condition of the issuer and the terms of the obligation. &lt;/div&gt;&lt;div style="margin-top:12pt;margin-bottom:0pt;font-size:10pt;font-family:arial;"&gt;&lt;span style="font-style:italic"&gt;Interest Rate Risk&lt;/span&gt; &#x2014; The market value of bonds and other fixed-income securities changes in response to interest rate changes and other factors. 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;/div&gt;&lt;div style="margin-top:12pt;margin-bottom:0pt;font-size:10pt;font-family:arial;"&gt;The Fund may be subject to a greater risk of rising interest rates during a period of low interest rates. For example, if interest rates increase by 1%, assuming a current portfolio duration of ten years, and all other factors being equal, the value of the Fund&#x2019;s investments would be expected to decrease by 10%. (Duration is a measure of the price sensitivity of a debt security or portfolio of debt securities to relative changes in interest rates.) The magnitude of these fluctuations in the market price of bonds and other fixed-income securities is generally greater for those securities with longer maturities. Fluctuations in the market price of the Fund&#x2019;s investments will not affect interest income derived from instruments already owned by the Fund, but will be reflected in the Fund&#x2019;s net asset value. The Fund may lose money if short-term or long-term interest rates rise sharply in a manner not anticipated by Fund management. &lt;/div&gt;&lt;div style="margin-top:12pt;margin-bottom:0pt;font-size:10pt;font-family:arial;"&gt;To the extent the Fund invests in debt securities that may be prepaid at the option of the obligor (such as mortgage-backed securities), the sensitivity of such securities to changes in interest rates may increase (to the detriment of the Fund) when interest rates rise. Moreover, because rates on certain floating rate debt securities typically reset only periodically, changes in prevailing interest rates (and particularly sudden and significant changes) can be expected to cause some fluctuations in the net asset value of the Fund to the extent that it invests in floating rate debt securities. &lt;/div&gt;&lt;div style="margin-top:12pt;margin-bottom:0pt;font-size:10pt;font-family:arial;"&gt;These basic principles of bond prices also apply to U.S. Government securities. A security backed by the &#x201c;full faith and credit&#x201d; of the U.S. Government is guaranteed only as to its stated interest rate and face value at maturity, not its current market price. Just like &lt;/div&gt;&lt;div style="margin-top:0pt;margin-bottom:0pt;font-size:10pt;font-family:arial;"&gt; other fixed-income securities, government-guaranteed securities will fluctuate in value when interest rates change. &lt;/div&gt;&lt;div style="margin-top:12pt;margin-bottom:0pt;font-size:10pt;font-family:arial;"&gt;A general rise in interest rates has the potential to cause investors to move out of fixed-income securities on a large scale, which may increase redemptions from funds that hold large amounts of fixed-income securities. Heavy redemptions could cause the Fund to sell assets at inopportune times or at a loss or depressed value and could hurt the Fund&#x2019;s performance. &lt;/div&gt;&lt;div style="margin-top:12pt;margin-bottom:0pt;font-size:10pt;font-family:arial;"&gt;&lt;span style="font-style:italic"&gt;Extension Risk&lt;/span&gt; &#x2014; When interest rates rise, certain obligations will be paid off by the obligor more slowly than anticipated, causing the value of these obligations to fall. &lt;/div&gt;&lt;div style="margin-top:12pt;margin-bottom:0pt;font-size:10pt;font-family:arial;"&gt;&lt;span style="font-style:italic"&gt;Prepayment Risk&lt;/span&gt; &#x2014; 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;/div&gt;</oef:RiskTextBlock>

The Fund could also suffer losses related to its derivatives positions as a result of unanticipated market movements, which losses are potentially unlimited. Finally, BFA may not be able to predict correctly the direction of securities prices, interest rates and other economic factors, which could cause the Fund&#x2019;s derivatives positions to lose value. &lt;/div&gt;&lt;div style="margin-top:12pt;margin-bottom:0pt;font-size:10pt;font-family:arial;"&gt;&lt;span style="font-style:italic"&gt;Counterparty Risk&lt;/span&gt; &#x2014; Derivatives are also subject to counterparty risk, which is the risk that the other party in the transaction will be unable or unwilling to fulfill its contractual obligation, and the related risks of having concentrated exposure to such a counterparty. &lt;/div&gt;&lt;div style="margin-top:12pt;margin-bottom:0pt;font-size:10pt;font-family:arial;"&gt;&lt;span style="font-style:italic"&gt;Illiquidity Risk&lt;/span&gt; &#x2014; 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 &lt;/div&gt;&lt;div style="margin-top:0pt;margin-bottom:0pt;font-size:10pt;font-family:arial;"&gt; to value accurately. &lt;/div&gt;&lt;div style="margin-top:12pt;margin-bottom:0pt;font-size:10pt;font-family:arial;"&gt;&lt;span style="font-style:italic"&gt;Operational Risk&lt;/span&gt; &#x2014; The use of derivatives includes the risk of potential operational issues, including documentation issues, settlement issues, systems failures, inadequate controls and human error. &lt;/div&gt;&lt;div style="margin-top:12pt;margin-bottom:0pt;font-size:10pt;font-family:arial;"&gt;&lt;span style="font-style:italic"&gt;Legal Risk&lt;/span&gt; &#x2014; The risk of insufficient documentation, insufficient capacity or authority of counterparty, or legality or enforceability of a contract. &lt;/div&gt;&lt;div style="margin-top:12pt;margin-bottom:0pt;font-size:10pt;font-family:arial;"&gt;&lt;span style="font-style:italic"&gt;Volatility and Correlation Risk&lt;/span&gt; &#x2014; Volatility is defined as the characteristic of a security, an index or a market to fluctuate significantly in price within a short time period. A risk of the Fund&#x2019;s use of derivatives is that the fluctuations in their values may not correlate with the overall securities markets. &lt;/div&gt;&lt;div style="margin-top:12pt;margin-bottom:0pt;font-size:10pt;font-family:arial;"&gt;&lt;span style="font-style:italic"&gt;Valuation Risk&lt;/span&gt; &#x2014; Valuation for derivatives may not be readily available in the market.

The value of inflation-indexed securities generally fluctuates with changes in real interest rates, decreasing when real interest rates rise and increasing when real interest rates fall. Real interest rates represent nominal (or stated) interest rates minus the inflation rates. If the Fund purchases TIPS in the secondary market and the bonds&#x2019; principal values previously were adjusted upward, but then there is a period of declining inflation rates, the Fund may receive at maturity less than it invested. &lt;/div&gt;&lt;div style="margin-top:12pt;margin-bottom:0pt;font-size:10pt;font-family:arial;"&gt;In addition, interest payments on inflation-indexed securities generally vary up or down along with the rate of inflation, and inflation-indexed bonds typically have lower nominal yields than conventional fixed-rate bonds. If the index measuring inflation falls, the principal value of inflation-indexed bonds will be adjusted downward, and consequently the interest payable on these securities (calculated with respect to a smaller principal amount) will be reduced. &lt;/div&gt;&lt;div style="margin-top:12pt;margin-bottom:0pt;font-size:10pt;font-family:arial;"&gt;Any increase in the principal amount of an inflation-indexed bond will be considered taxable ordinary income, even though investors do not receive their principal until maturity. Periodic adjustments for inflation to the principal amount of an inflation-indexed bond may give rise to original issue discount, which will be includable in the Fund&#x2019;s gross income. Due to original issue discount, the Fund may be required to make annual distributions to shareholders that exceed the cash received, which may cause the Fund to liquidate certain investments when it is not advantageous to do so. Also, if the principal value of an inflation-indexed bond is adjusted downward due to deflation, amounts previously distributed in the taxable year may be characterized in some circumstances as a return of capital. &lt;/div&gt;</oef:RiskTextBlock>

In addition, under certain circumstances, non &lt;/div&gt;&lt;div style="margin-top:0pt;margin-bottom:0pt;font-size:10pt;font-family:arial;"&gt; redeeming shareholders may be treated as receiving a disproportionately large taxable distribution during or with respect to such tax year. In some circumstances, the Fund may hold a relatively large proportion of its assets in cash in anticipation of large redemptions, diluting its investment returns. To the extent the Fund permits redemptions in cash, these large redemptions may also force the Fund to sell portfolio securities when it might not otherwise do so, which may negatively impact the Fund&#x2019;s NAV, increase the Fund&#x2019;s brokerage costs and/or have a material effect on the market price of the Fund shares. &lt;/div&gt;</oef:RiskTextBlock>

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;/div&gt;</oef:RiskTextBlock>

The high volatility of precious metal prices may adversely affect the financial condition of companies involved with precious metals. The production and sale of precious metals by governments or central banks or other larger holders can be affected by various economic, financial, social and political factors, which may be unpredictable and may have a significant impact on the prices of precious metals. Other factors that may affect the prices of precious metals and securities related to them include changes in inflation, the outlook for inflation and changes in industrial and commercial demand for precious metals. &lt;/div&gt;</oef:RiskTextBlock>

Many factors may affect real estate values. These factors include both the general and local economies, vacancy rates, changes in rent schedules, tenant bankruptcies, the ability to re&#x2011;lease space under expiring leases on attractive terms, the amount of new construction in a particular area, the laws and regulations (including zoning, environmental and tax laws) affecting real estate and the costs of owning, maintaining and improving real estate. The availability of mortgage financing and changes in interest rates may also affect real estate values. If the Fund&#x2019;s real estate-related investments are concentrated in one geographic area or in one property type, the Fund will be particularly subject to the risks associated with that area or property type. Many issuers of real estate-related securities are highly leveraged, which increases the risk to holders of such securities. The value of the securities the Fund buys will not necessarily track the value of the underlying investments of the issuers of such securities. In addition, certain issuers of real estate-related securities may have developed or commenced development on properties and may develop additional properties in the future. Real estate &lt;/div&gt;&lt;div style="margin-top:0pt;margin-bottom:0pt;font-size:10pt;font-family:arial;"&gt; development involves significant risks in addition to those involved in the ownership and operation of established properties. Real estate securities may have limited diversification and are, therefore, subject to risks inherent in operating and financing a limited number of projects. Real estate securities are also subject to heavy cash flow dependency and defaults by borrowers or tenants. &lt;/div&gt;</oef:RiskTextBlock>

The Fund may engage in short sales and gain short exposure through certain derivative instruments, such as futures, options or swaps. The Fund may lose more money than the actual cost of a short sale or position and the potential losses are theoretically unlimited on a short sale or position. &lt;/div&gt;</oef:RiskTextBlock>

Structured notes may be leveraged, increasing the volatility of each structured note&#x2019;s value relative to the change in the reference measure. Structured notes may also be less liquid and more difficult to price accurately than less complex securities and instruments or more traditional debt securities. &lt;/div&gt;</oef:RiskTextBlock>

The Predecessor Fund had the same investment objective and substantially similar investment strategies as the Fund as of the date of the Reorganization.

The table compares the Fund&#x2019;s performance to that of the MSCI World Index (Net) and the MSCI ACWI Minimum Volatility Index (USD) (Net). The MSCI ACWI Minimum Volatility Index (USD) (Net) is relevant to the Fund because it has characteristics similar to the Fund&#x2019;s investment strategy. To the extent that dividends and distributions have been paid by the Fund, the performance information for the Fund in the chart and table assumes reinvestment of the dividends and distributions. As with all such investments, past performance (before and after taxes) is not an indication of future results. If the Fund&#x2019;s investment manager and its affiliates had not waived or reimbursed certain Fund expenses during these periods, the Predecessor Fund&#x2019;s returns would have been lower. &lt;/div&gt;</oef:PerformanceNarrativeTextBlock>

The Fund seeks to achieve its investment objective by investing in both equity and fixed-income securities, including money market securities and other short-term securities or instruments, of issuers located around the world. Equity securities include common stock, preferred stock, American Depository Receipts, or securities or other instruments whose price is linked to the value of common stock. The combination of equity securities will be varied from time to time both with respect to types of securities and markets in response to changing market and economic trends. The Fund may also purchase convertible securities. The Fund may invest in the securities of companies of any market capitalization. The Fund may also invest in Real Estate Investment Trusts. &lt;/div&gt;&lt;div style="margin-top:12pt;margin-bottom:0pt;font-size:10pt;font-family:arial;"&gt;Generally, the Fund seeks diversification across markets, industries and issuers. In making investment decisions, Fund management seeks to identify the long term trends and changes that Fund management believes could benefit particular markets, industries and/or issuers relative to other markets, industries and/or issuers, respectively. Fund management will consider a variety of factors when selecting the markets, such as the rate of economic growth, natural resources, capital reinvestment and the social and political environment. &lt;/div&gt;&lt;div style="margin-top:12pt;margin-bottom:0pt;font-size:10pt;font-family:arial;"&gt;The Fund may invest in developed and emerging markets, including frontier markets. This flexibility allows Fund management to look for investments in markets around the world that it believes will provide the best relative asset allocation to meet the Fund&#x2019;s objective. In pursuing its investment objective, the Fund may utilize short positions. The Fund expects to &lt;/div&gt;&lt;div style="margin-top:0pt;margin-bottom:0pt;font-size:10pt;font-family:arial;"&gt; implement short positions through short sales of any instrument that the Fund may purchase for investment or by using options, swaps, futures, forwards, contracts for difference or other derivative instruments. &lt;/div&gt;&lt;div style="margin-top:12pt;margin-bottom:0pt;font-size:10pt;font-family:arial;"&gt;With respect to the Fund&#x2019;s fixed-income investments, the Fund may invest in all types of debt securities, including, but not limited to, U.S. and foreign government bonds, corporate bonds and convertible bonds, structured notes, credit-linked notes, loan assignments and participations, mortgage- and asset-backed securities, and securities issued or guaranteed by certain international organizations such as the World Bank. The Fund may invest in &#x201c;junk&#x201d; bonds, corporate loans and distressed securities. These securities offer the possibility of relatively higher returns but are significantly riskier than higher rated debt securities. The Fund may invest in debt securities of any maturity or duration. &lt;/div&gt;&lt;div style="margin-top:12pt;margin-bottom:0pt;font-size:10pt;font-family:arial;"&gt;The Fund may use derivatives, including options, futures, swaps (including, but not limited to, total return swaps that may be referred to as contracts for difference), credit default swaps and forward contracts both to seek to increase the return of the Fund and to hedge (or protect) the value of its assets against adverse movements in currency exchange rates, interest rates and movements in the securities markets. Derivatives are financial instruments whose value is derived from another security, a commodity, a currency or an index. The Fund has the ability to use forward currency contracts and other currency derivatives. From time to time, the Fund may own foreign cash equivalents or foreign bank deposits as part of the Fund&#x2019;s investment strategy. The Fund may also invest in non&#x2011;U.S. currencies, however, the Fund may underweight or overweight a currency based on the Fund management team&#x2019;s outlook. The Fund may invest in indexed and inverse securities. &lt;/div&gt;&lt;div style="margin-top:12pt;margin-bottom:0pt;font-size:10pt;font-family:arial;"&gt;The Fund may invest a portion of its assets in securities related to real assets (like real estate- or precious metals-related securities) such as stock, bonds or convertible bonds issued by real estate investment trusts or companies that mine precious metals. The Fund may hold a portion of its assets in cash or cash equivalents. &lt;/div&gt;&lt;div style="margin-top:12pt;margin-bottom:0pt;font-size:10pt;font-family:arial;"&gt;The Fund may seek to provide exposure to the investment returns of real assets that trade in the commodity markets through investment in commodity-linked derivative instruments and investment vehicles such as exchange traded funds that invest exclusively in commodities and are designed to provide this exposure without direct investment in physical &lt;/div&gt;&lt;div style="margin-top:0pt;margin-bottom:0pt;font-size:10pt;font-family:arial;"&gt; commodities. The Fund may gain exposure to commodity markets by investing up to 25% of its total assets in Cayman GA Dynamic Equity Fund, Ltd. (the &#x201c;Subsidiary&#x201d;), a wholly owned subsidiary of the Fund following the reorganization formed in the Cayman Islands, which invests primarily in commodity-related instruments. The Subsidiary may also hold cash and invest in other instruments, including fixed income securities, either as investments or to serve as margin or collateral for the Subsidiary&#x2019;s derivative positions.

An investor could lose money over short periods due to fluctuation in the Fund&#x2019;s net asset value in response to short-term market movements and over longer periods during market downturns. Securities or other investments held by the Fund may underperform the markets, the relevant indices or benchmarks, or the securities selected by other funds with similar investment objectives and investment strategies, or may otherwise fail to perform as intended. The value of a security or other asset may decline due to changes in general market conditions, economic trends or events that are not specifically related to the issuer of the security or other asset, or factors that affect a particular issuer or issuers, exchange, country, group of countries, region, market, industry, group of industries, sector or asset class. The success of the Fund&#x2019;s activities could be affected by interest rates, availability of credit, inflation rates, economic uncertainty, changes in laws, tariffs and trade barriers, supply chain disruptions, economic sanctions, currency exchange controls, and local, regional or global events such as war, acts of &lt;/div&gt;&lt;div style="margin-top:0pt;margin-bottom:0pt;font-size:10pt;font-family:arial;"&gt; terrorism, natural and environmental disasters, the spread of infectious illness or other public health issues, recessions, or other events. &lt;/div&gt;&lt;div style="margin-top:12pt;margin-bottom:0pt;font-size:10pt;font-family:arial;"&gt;Recent policy initiatives undertaken by the U.S. government have the potential to impact international relations, trade agreements and the overall regulatory environment in ways that could create uncertainty and instability in domestic and global markets, and could adversely affect the investment performance of the Fund. In particular, actions taken by the U.S. government in respect of international trade relations could lead to trade wars, increased costs for imported goods, disruptions in supply chains, reduced foreign investment, and instability in regions where the Fund invests. &lt;/div&gt;</oef:RiskTextBlock>

Since it derives a portion of its value from the common stock into which it may be converted, a convertible security is also subject to the same types of market and issuer risks that apply to the underlying common stock, including the potential for increased volatility in the price of the convertible security. &lt;/div&gt;</oef:RiskTextBlock>

Borrowers generally pay interest on corporate loans at rates that change in response to changes in market interest rates such as the Secured Overnight Financing Rate (&#x201c;SOFR&#x201d;) 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 and wide bid/ask spreads. In addition, transactions in corporate loans may settle on a delayed basis. As a result, the proceeds from the sale of corporate loans may not be readily available to make additional investments or to meet the Fund&#x2019;s redemption obligations. To the extent the extended settlement process gives rise to short-term liquidity needs, the Fund may hold additional cash, sell investments or temporarily borrow from banks and other lenders. &lt;/div&gt;</oef:RiskTextBlock>

Changes in an issuer&#x2019;s credit rating or the market&#x2019;s perception of an issuer&#x2019;s creditworthiness may also affect the value of the Fund&#x2019;s investment in that issuer. The degree of credit risk depends on both the financial condition of the issuer and the terms of the obligation. &lt;/div&gt;&lt;div style="margin-top:0pt;margin-bottom:0pt;font-size:10pt;font-family:arial;"&gt;&lt;span style="font-style:italic"&gt;Interest Rate Risk&lt;/span&gt; &#x2014; The market value of bonds and other fixed-income securities changes in response to interest rate changes and other factors. 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;/div&gt;&lt;div style="margin-top:12pt;margin-bottom:0pt;font-size:10pt;font-family:arial;"&gt;The Fund may be subject to a greater risk of rising interest rates during a period of low interest rates. For example, if interest rates increase by 1%, assuming a current portfolio duration of ten years, and all other factors being equal, the value of the Fund&#x2019;s investments would be expected to decrease by 10%. (Duration is a measure of the price sensitivity of a debt security or portfolio of debt securities to relative changes in interest rates.) The magnitude of these fluctuations in the market price of bonds and other fixed-income securities is generally greater for those securities with longer maturities. Fluctuations in the market price of the Fund&#x2019;s investments will not affect interest income derived from instruments already owned by the Fund, but will be reflected in the Fund&#x2019;s net asset value. The Fund may lose money if short-term or long-term interest rates rise sharply in a manner not anticipated by Fund management. &lt;/div&gt;&lt;div style="margin-top:12pt;margin-bottom:0pt;font-size:10pt;font-family:arial;"&gt;To the extent the Fund invests in debt securities that may be prepaid at the option of the obligor (such as mortgage-backed securities), the sensitivity of such securities to changes in interest rates may increase (to the detriment of the Fund) when interest rates rise. Moreover, because rates on certain floating rate debt securities typically reset only periodically, changes in prevailing interest rates (and particularly sudden and significant changes) can be expected to cause some fluctuations in the net asset value of the Fund to the extent that it invests in floating rate debt securities. &lt;/div&gt;&lt;div style="margin-top:12pt;margin-bottom:0pt;font-size:10pt;font-family:arial;"&gt;These basic principles of bond prices also apply to U.S. Government securities. A security backed by the &#x201c;full faith and credit&#x201d; of the U.S. Government is guaranteed only as to its stated interest rate and face value at maturity, not its current market price. Just like other fixed-income securities, government-guaranteed securities will fluctuate in value when interest rates change. &lt;/div&gt;&lt;div style="margin-top:12pt;margin-bottom:0pt;font-size:10pt;font-family:arial;"&gt;A general rise in interest rates has the potential to cause investors to move out of fixed-income securities on a large scale, which may increase redemptions from funds that hold large amounts of fixed-income securities. Heavy redemptions could cause the Fund to sell assets at inopportune times or at a loss or depressed value and could hurt the Fund&#x2019;s performance. &lt;/div&gt;&lt;div style="margin-top:0pt;margin-bottom:0pt;font-size:10pt;font-family:arial;"&gt;&lt;span style="font-style:italic"&gt;Extension Risk&lt;/span&gt; &#x2014; When interest rates rise, certain obligations will be paid off by the obligor more slowly than anticipated, causing the value of these obligations to fall. &lt;/div&gt;&lt;div style="margin-top:12pt;margin-bottom:0pt;font-size:10pt;font-family:arial;"&gt;&lt;span style="font-style:italic"&gt;Prepayment Risk&lt;/span&gt; &#x2014; 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;/div&gt;</oef:RiskTextBlock>

The Fund could also suffer losses related to its derivatives positions as a result of unanticipated market movements, which losses are potentially unlimited.

In addition, under certain circumstances, non redeeming shareholders may be treated as receiving a disproportionately large taxable distribution during or with respect to such tax year. In some circumstances, the Fund may hold a relatively large proportion of its assets in cash in anticipation of large redemptions, diluting its investment returns. To the extent the Fund permits redemptions in cash, these large redemptions may also force the Fund to sell portfolio securities when it might not otherwise do so, which may negatively impact the Fund&#x2019;s NAV, increase the Fund&#x2019;s brokerage costs and/or have a material effect on the market price of the Fund shares. &lt;/div&gt;</oef:RiskTextBlock>

Many factors may affect real estate values. These factors include both the general and local economies, vacancy rates, changes in rent schedules, tenant bankruptcies, the ability to re&#x2011;lease space under expiring leases on attractive terms, the amount of new construction in a particular area, the laws and regulations (including zoning, environmental and tax laws) affecting real estate and the costs of owning, maintaining and improving real estate. The availability of mortgage financing and changes in interest rates may also affect real estate values. If the Fund&#x2019;s real estate-related investments are concentrated in one geographic area or in one property type, the Fund will be particularly subject to the risks associated with that area or property type. Many issuers of real estate-related securities are highly leveraged, which increases the risk to holders of such securities. The value of the securities the Fund buys will not necessarily track the value of the underlying investments of the issuers of such securities. In addition, certain issuers of real estate-related securities may have developed or commenced development on properties and may develop additional properties in the future. Real estate development involves significant risks in addition to those involved in the ownership and operation of established properties. Real estate securities may have limited diversification and are, therefore, subject &lt;/div&gt;&lt;div style="margin-top:0pt;margin-bottom:0pt;font-size:10pt;font-family:arial;"&gt; to risks inherent in operating and financing a limited number of projects. Real estate securities are also subject to heavy cash flow dependency and defaults by borrowers or tenants. &lt;/div&gt;</oef:RiskTextBlock>

In such situations, the Fund will incur a loss as a result of a short sale or position if the price of the reference instrument increases after the Fund entered into the short sale or position. The Fund may engage in short sales and gain short exposure through certain derivative instruments, such as futures, options or swaps.

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. </xhtml:div></link:footnote>

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. </xhtml:div></link:footnote>
