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 historically low interest rates. For &lt;/span&gt;&lt;span style="color:#000000;font-family:arial;font-size:9.30pt"&gt;example, if interest rates increase by 1%, assuming a current portfolio duration of ten years, and all other factors &lt;/span&gt;&lt;span style="color:#000000;font-family:arial;font-size:9.30pt"&gt;being equal, the value of the Fund&#x2019;s investments would be expected to decrease by 10%. (Duration is a measure of &lt;/span&gt;&lt;span style="color:#000000;font-family:arial;font-size:9.30pt"&gt;the price sensitivity of a debt security or portfolio of debt securities to relative changes in interest rates). The &lt;/span&gt;&lt;span style="color:#000000;font-family:arial;font-size:9.30pt"&gt;magnitude of these fluctuations in the market price of bonds and other fixed-income securities is generally greater &lt;/span&gt;&lt;span style="color:#000000;font-family:arial;font-size:9.30pt"&gt;for those securities with longer maturities. Fluctuations in the market price of the Fund&#x2019;s investments will not affect &lt;/span&gt;&lt;span style="color:#000000;font-family:arial;font-size:9.30pt"&gt;interest income derived from instruments already owned by the Fund, but will be reflected in the Fund&#x2019;s net asset &lt;/span&gt;&lt;span style="color:#000000;font-family:arial;font-size:9.30pt"&gt;value. The Fund may lose money if short-term or long-term interest rates rise sharply in a manner not anticipated by &lt;/span&gt;&lt;span style="color:#000000;font-family:arial;font-size:9.30pt"&gt;Fund 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.

Borrowers generally pay interest on corporate loans at &lt;/span&gt;&lt;span style="color:#000000;font-family:arial;font-size:9.30pt"&gt;rates that change in response to changes in market interest rates such as the Secured Overnight Financing Rate &lt;/span&gt;&lt;span style="color:#000000;font-family:arial;font-size:9.30pt"&gt;(&#x201c;SOFR&#x201d;), or the prime rates of U.S. banks.

An illiquid investment is any &lt;/span&gt;&lt;span style="color:#000000;font-family:arial;font-size:9.30pt"&gt;investment that the Fund reasonably expects cannot be sold or disposed of in current market conditions in seven &lt;/span&gt;&lt;span style="color:#000000;font-family:arial;font-size:9.30pt"&gt;calendar days or less without the sale or disposition significantly changing the market value of the investment. &lt;/span&gt;&lt;span style="color:#000000;font-family:arial;font-size:9.30pt"&gt;Liquid investments may become illiquid after purchase by the Fund, particularly during periods of market turmoil. &lt;/span&gt;&lt;span style="color:#000000;font-family:arial;font-size:9.30pt"&gt;There can be no assurance that a security or instrument that is deemed to be liquid when purchased will continue &lt;/span&gt;&lt;span style="color:#000000;font-family:arial;font-size:9.30pt"&gt;to be liquid for as long as it is held by the Fund, and any security or instrument held by the Fund may be deemed an &lt;/span&gt;&lt;span style="color:#000000;font-family:arial;font-size:9.30pt"&gt;illiquid investment pursuant to the Fund&#x2019;s liquidity risk management program. The Fund&#x2019;s illiquid investments may &lt;/span&gt;&lt;span style="color:#000000;font-family:arial;font-size:9.30pt"&gt;reduce the returns of the Fund because it may be difficult to sell the illiquid investments at an advantageous time &lt;/span&gt;&lt;span style="color:#000000;font-family:arial;font-size:9.30pt"&gt;or price. In addition, if the Fund is limited in its ability to dispose of illiquid investments during periods when &lt;/span&gt;&lt;span style="color:#000000;font-family:arial;font-size:9.30pt"&gt;shareholders are redeeming or selling their shares, or the Fund&#x2019;s net assets otherwise shrink the Fund will need to &lt;/span&gt;&lt;span style="color:#000000;font-family:arial;font-size:9.30pt"&gt;dispose of liquid securities to meet redemption requests and illiquid securities will become a larger portion of the &lt;/span&gt;&lt;span style="color:#000000;font-family:arial;font-size:9.30pt"&gt;Fund&#x2019;s holdings. An investment may be illiquid due to, among other things, the reduced number and capacity of &lt;/span&gt;&lt;span style="color:#000000;font-family:arial;font-size:9.30pt"&gt;traditional market participants to make a market in fixed-income securities or the lack of an active trading market. &lt;/span&gt;&lt;span style="color:#000000;font-family:arial;font-size:9.30pt"&gt;To the extent that the Fund&#x2019;s principal investment strategies involve derivatives or securities with substantial market &lt;/span&gt;&lt;span style="color:#000000;font-family:arial;font-size:9.30pt"&gt;and/or credit risk, the Fund will tend to have greater exposure to the risks associated with illiquid investments. &lt;/span&gt;&lt;span style="color:#000000;font-family:arial;font-size:9.30pt"&gt;Illiquid investments may be harder to value, especially in changing markets, and if the Fund is forced to sell these &lt;/span&gt;&lt;span style="color:#000000;font-family:arial;font-size:9.30pt"&gt;investments to meet redemption requests or for other cash needs, the Fund may suffer a loss. This may be &lt;/span&gt;&lt;span style="color:#000000;font-family:arial;font-size:9.30pt"&gt;magnified in a rising interest rate environment or other circumstances where investor redemptions or sales of Fund &lt;/span&gt;&lt;span style="color:#000000;font-family:arial;font-size:9.30pt"&gt;shares may be higher than normal. In addition, when there is illiquidity in the market for certain securities, the &lt;/span&gt;&lt;span style="color:#000000;font-family:arial;font-size:9.30pt"&gt;Fund, due to limitations on illiquid investments, may be subject to purchase and sale restrictions.&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>

Many factors may affect real estate values. These factors include both the &lt;/span&gt;&lt;span style="color:#000000;font-family:arial;font-size:9.30pt"&gt;general and local economies, vacancy rates, changes in rent schedules, tenant bankruptcies, the ability to re-lease &lt;/span&gt;&lt;span style="color:#000000;font-family:arial;font-size:9.30pt"&gt;space under expiring leases on attractive terms, the amount of new construction in a particular area, the laws and &lt;/span&gt;&lt;span style="color:#000000;font-family:arial;font-size:9.30pt"&gt;regulations (including zoning, environmental and tax laws) affecting real estate and the costs of owning, maintaining &lt;/span&gt;&lt;span style="color:#000000;font-family:arial;font-size:9.30pt"&gt;and improving real estate. The availability of mortgage financing and changes in interest rates may also affect real &lt;/span&gt;&lt;span style="color:#000000;font-family:arial;font-size:9.30pt"&gt;estate values. If the Fund&#x2019;s real estate-related investments are concentrated in one geographic area or in one &lt;/span&gt;&lt;span style="color:#000000;font-family:arial;font-size:9.30pt"&gt;property type, the Fund will be particularly subject to the risks associated with that area or property type. Many &lt;/span&gt;&lt;span style="color:#000000;font-family:arial;font-size:9.30pt"&gt;issuers of real estate-related securities are highly leveraged, which increases the risk to holders of such securities. &lt;/span&gt;&lt;span style="color:#000000;font-family:arial;font-size:9.30pt"&gt;The value of the securities the Fund buys will not necessarily track the value of the underlying investments of the &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="line-height:10.695pt;margin-left:12pt;text-align:left;"&gt;&lt;span style="color:#000000;font-family:arial;font-size:9.30pt"&gt;issuers of such securities. In addition, certain issuers of real estate-related securities may have developed or &lt;/span&gt;&lt;span style="color:#000000;font-family:arial;font-size:9.30pt"&gt;commenced development on properties and may develop additional properties in the future. Real estate &lt;/span&gt;&lt;span style="color:#000000;font-family:arial;font-size:9.30pt"&gt;development involves significant risks in addition to those involved in the ownership and operation of established &lt;/span&gt;&lt;span style="color:#000000;font-family:arial;font-size:9.30pt"&gt;properties. Real estate securities may have limited diversification and are, therefore, subject to risks inherent in &lt;/span&gt;&lt;span style="color:#000000;font-family:arial;font-size:9.30pt"&gt;operating and financing a limited number of projects. Real estate securities are also subject to heavy cash flow &lt;/span&gt;&lt;span style="color:#000000;font-family:arial;font-size:9.30pt"&gt;dependency and defaults by borrowers or tenants.&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>

In April 2023, however, the FCA announced that some USD LIBOR settings would continue to be published &lt;/span&gt;&lt;span style="color:#000000;font-family:arial;font-size:9.30pt"&gt;under a synthetic methodology until September 30, 2024 for certain legacy contracts. After September 30, 2024, &lt;/span&gt;&lt;span style="color:#000000;font-family:arial;font-size:9.30pt"&gt;the remaining synthetic LIBOR settings ceased to be published, and all LIBOR settings have permanently ceased. &lt;/span&gt;&lt;span style="color:#000000;font-family:arial;font-size:9.30pt"&gt;The Secured Overnight Financing Rate (&#x201c;SOFR&#x201d;) is a broad measure of the cost of borrowing cash overnight &lt;/span&gt;&lt;span style="color:#000000;font-family:arial;font-size:9.30pt"&gt;collateralized by U.S. Treasury securities in the repurchase agreement (&#x201c;repo&#x201d;) market and has been used &lt;/span&gt;&lt;span style="color:#000000;font-family:arial;font-size:9.30pt"&gt;increasingly on a voluntary basis in new instruments and transactions. Under U.S. regulations that implement a &lt;/span&gt;&lt;span style="color:#000000;font-family:arial;font-size:9.30pt"&gt;statutory fallback mechanism to replace LIBOR, benchmark rates based on SOFR have replaced LIBOR in certain &lt;/span&gt;&lt;span style="color:#000000;font-family:arial;font-size:9.30pt"&gt;financial contracts.&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;Neither the effect of the LIBOR transition process nor its ultimate success can yet be known.

An economic downturn generally leads to a higher non-payment rate, and a senior &lt;/span&gt;&lt;span style="color:#000000;font-family:arial;font-size:9.30pt"&gt;loan may lose significant value before a default occurs. Moreover, any specific collateral used to secure a senior &lt;/span&gt;&lt;span style="color:#000000;font-family:arial;font-size:9.30pt"&gt;loan may decline in value or become illiquid, which would adversely affect the senior loan&#x2019;s value. No active trading &lt;/span&gt;&lt;span style="color:#000000;font-family:arial;font-size:9.30pt"&gt;market may exist for certain senior loans, which may impair the ability of the Fund to realize full value in the event &lt;/span&gt;&lt;span style="color:#000000;font-family:arial;font-size:9.30pt"&gt;of the need to sell a senior loan and which may make it difficult to value senior loans. Although senior loans in &lt;/span&gt;&lt;span style="color:#000000;font-family:arial;font-size:9.30pt"&gt;which the Fund will invest generally will be secured by specific collateral, there can be no assurance that liquidation &lt;/span&gt;&lt;span style="color:#000000;font-family:arial;font-size:9.30pt"&gt;of such collateral would satisfy the borrower&#x2019;s obligation in the event of non-payment of scheduled interest or &lt;/span&gt;&lt;span style="color:#000000;font-family:arial;font-size:9.30pt"&gt;principal or that such collateral could be readily liquidated. To the extent that a senior loan is collateralized by stock &lt;/span&gt;&lt;span style="color:#000000;font-family:arial;font-size:9.30pt"&gt;in the borrower or its subsidiaries, such stock may lose all of its value in the event of the bankruptcy of the &lt;/span&gt;&lt;span style="color:#000000;font-family:arial;font-size:9.30pt"&gt;borrower. Uncollateralized senior loans involve a greater risk of loss.&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 trading prices of an ETF&#x2019;s shares fluctuate continuously throughout trading hours based on &lt;/span&gt;&lt;span style="color:#000000;font-family:arial;font-size:9.30pt"&gt;market supply and demand rather than net asset value. The trading prices of an ETF&#x2019;s shares may deviate &lt;/span&gt;&lt;span style="color:#000000;font-family:arial;font-size:9.30pt"&gt;significantly from net asset value during periods of market volatility. Any of these factors may lead to an ETF&#x2019;s &lt;/span&gt;&lt;span style="color:#000000;font-family:arial;font-size:9.30pt"&gt;shares trading at a premium or discount to net asset value.

While the creation/redemption feature is designed to make it likely that an ETF&#x2019;s &lt;/span&gt;&lt;span style="color:#000000;font-family:arial;font-size:9.30pt"&gt;shares normally trade on exchanges at prices close to the ETF&#x2019;s next calculated net asset value, exchange prices &lt;/span&gt;&lt;span style="color:#000000;font-family:arial;font-size:9.30pt"&gt;are not expected to correlate exactly with an ETF&#x2019;s net asset value due to timing reasons as well as market supply &lt;/span&gt;&lt;span style="color:#000000;font-family:arial;font-size:9.30pt"&gt;and demand factors. In addition, disruptions to creations and redemptions or the existence of extreme market &lt;/span&gt;&lt;span style="color:#000000;font-family:arial;font-size:9.30pt"&gt;volatility may result in trading prices that differ significantly from net asset value. If a shareholder purchases at a &lt;/span&gt;&lt;span style="color:#000000;font-family:arial;font-size:9.30pt"&gt;time when the market price is at a premium to the net asset value or sells at a time when the market price is at a &lt;/span&gt;&lt;span style="color:#000000;font-family:arial;font-size:9.30pt"&gt;discount to the net asset value, the shareholder may sustain losses. The use of cash creations and redemptions &lt;/span&gt;&lt;span style="color:#000000;font-family:arial;font-size:9.30pt"&gt;may also cause the ETFs&#x2019; shares to trade in the market at greater bid-ask spreads or greater premiums or &lt;/span&gt;&lt;span style="color:#000000;font-family:arial;font-size:9.30pt"&gt;discounts to the ETFs&#x2019; NAV.&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 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.

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>

Securities with floating or variable interest rates can be less sensitive to &lt;/span&gt;&lt;span style="color:#000000;font-family:arial;font-size:9.30pt"&gt;interest rate changes than securities with fixed interest rates, but may decline in value if their coupon rates do not &lt;/span&gt;&lt;span style="color:#000000;font-family:arial;font-size:9.30pt"&gt;reset as high, or as quickly, as comparable market interest rates, and generally carry lower yields than fixed &lt;/span&gt;&lt;span style="color:#000000;font-family:arial;font-size:9.30pt"&gt;securities of the same maturity. These securities will not generally increase in value if interest rates decline. A &lt;/span&gt;&lt;span style="color:#000000;font-family:arial;font-size:9.30pt"&gt;decline in interest rates may result in a reduction in income received from variable and floating rate securities held &lt;/span&gt;&lt;span style="color:#000000;font-family:arial;font-size:9.30pt"&gt;by the Fund and may adversely affect the value of the Fund&#x2019;s shares.

Floating rate securities generally are &lt;/span&gt;&lt;span style="color:#000000;font-family:arial;font-size:9.30pt"&gt;subject to legal or contractual restrictions on resale, may trade infrequently, and their value may be impaired when &lt;/span&gt;&lt;span style="color:#000000;font-family:arial;font-size:9.30pt"&gt;the Fund needs to liquidate such loans. Benchmark interest rates may not accurately track market interest rates. &lt;/span&gt;&lt;span style="color:#000000;font-family:arial;font-size:9.30pt"&gt;Although floating rate securities are less sensitive to interest rate risk than fixed-rate securities, they are subject to &lt;/span&gt;&lt;span style="color:#000000;font-family:arial;font-size:9.30pt"&gt;credit risk and default risk, which could impair their value.&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&#x2019;s investment in non-dollar denominated bonds may be on a currency hedged or unhedged basis. The &lt;/span&gt;&lt;span style="color:#000000;font-family:arial;font-size:9.30pt"&gt;Fund may invest in fixed-income securities of both U.S. and non-U.S. issuers, including emerging market issuers, &lt;/span&gt;&lt;span style="color:#000000;font-family:arial;font-size:9.30pt"&gt;without limit.&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 average portfolio duration of the Fund will vary based on the management team&#x2019;s forecast of interest rates and &lt;/span&gt;&lt;span style="color:#000000;font-family:arial;font-size:9.30pt"&gt;there are no limits regarding portfolio duration or average maturity.&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 may invest in common stock and preferred stock. The Fund &lt;/span&gt;&lt;span style="color:#000000;font-family:arial;font-size:9.30pt"&gt;generally intends to invest in dividend paying stocks. From time to time, the Fund may invest in shares of companies &lt;/span&gt;&lt;span style="color:#000000;font-family:arial;font-size:9.30pt"&gt;through initial public offerings (&#x201c;IPOs&#x201d;). The Fund may invest in securities of both U.S. or non-U.S. issuers, including &lt;/span&gt;&lt;span style="color:#000000;font-family:arial;font-size:9.30pt"&gt;emerging market issuers, without limit, which can be U.S. dollar based or non-U.S. dollar based and may be currency &lt;/span&gt;&lt;span style="color:#000000;font-family:arial;font-size:9.30pt"&gt;hedged or unhedged.

The &lt;/span&gt;&lt;span style="color:#000000;font-family:arial;font-size:9.30pt"&gt;Fund&#x2019;s use of derivatives will be primarily as part of a strategy designed to reduce exposure to other risks, such as &lt;/span&gt;&lt;span style="color:#000000;font-family:arial;font-size:9.30pt"&gt;currency risk. The Fund may also use derivatives as a substitute for taking a position in the underlying asset. The Fund &lt;/span&gt;&lt;span style="color:#000000;font-family:arial;font-size:9.30pt"&gt;may seek to obtain market exposure to the securities in which it primarily invests by entering into a series of purchase &lt;/span&gt;&lt;span style="color:#000000;font-family:arial;font-size:9.30pt"&gt;and sale contracts or by using other investment techniques (such as reverse repurchase agreements or dollar rolls). &lt;/span&gt;&lt;span style="color:#000000;font-family:arial;font-size:9.30pt"&gt;The underlying funds and ETFs in which the Fund invests may, to varying degrees, also invest in derivatives. The Fund &lt;/span&gt;&lt;span style="color:#000000;font-family:arial;font-size:9.30pt"&gt;may also engage in option writing to generate additional income in the portfolio.&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;As part of the Fund&#x2019;s risk management process, the Fund may allocate, without limitation, assets into cash or short-term&lt;/span&gt;&lt;span style="color:#000000;font-family:arial;font-size:9.30pt"&gt; fixed-income securities, and away from riskier assets such as equity and high yield fixed-income 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;The Fund may engage in active and frequent trading of portfolio securities to achieve its primary investment strategies.&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;/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"&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 historically low interest rates. For &lt;/span&gt;&lt;span style="color:#000000;font-family:arial;font-size:9.30pt"&gt;example, if interest rates increase by 1%, assuming a current portfolio duration of ten years, and all other factors &lt;/span&gt;&lt;span style="color:#000000;font-family:arial;font-size:9.30pt"&gt;being equal, the value of the Fund&#x2019;s investments would be expected to decrease by 10%. (Duration is a measure of &lt;/span&gt;&lt;span style="color:#000000;font-family:arial;font-size:9.30pt"&gt;the price sensitivity of a debt security or portfolio of debt securities to relative changes in interest rates). The &lt;/span&gt;&lt;span style="color:#000000;font-family:arial;font-size:9.30pt"&gt;magnitude of these fluctuations in the market price of bonds and other fixed-income securities is generally greater &lt;/span&gt;&lt;span style="color:#000000;font-family:arial;font-size:9.30pt"&gt;for those securities with longer maturities. Fluctuations in the market price of the Fund&#x2019;s investments will not affect &lt;/span&gt;&lt;span style="color:#000000;font-family:arial;font-size:9.30pt"&gt;interest income derived from instruments already owned by the Fund, but will be reflected in the Fund&#x2019;s net asset &lt;/span&gt;&lt;span style="color:#000000;font-family:arial;font-size:9.30pt"&gt;value. The Fund may lose money if short-term or long-term interest rates rise sharply in a manner not anticipated by &lt;/span&gt;&lt;span style="color:#000000;font-family:arial;font-size:9.30pt"&gt;Fund 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 Fund&#x2019;s illiquid investments may &lt;/span&gt;&lt;span style="color:#000000;font-family:arial;font-size:9.30pt"&gt;reduce the returns of the Fund because it may be difficult to sell the illiquid investments at an advantageous time &lt;/span&gt;&lt;span style="color:#000000;font-family:arial;font-size:9.30pt"&gt;or price.

Many factors may affect real estate values. These factors include both the &lt;/span&gt;&lt;span style="color:#000000;font-family:arial;font-size:9.30pt"&gt;general and local economies, vacancy rates, changes in rent schedules, tenant bankruptcies, the ability to re-lease &lt;/span&gt;&lt;span style="color:#000000;font-family:arial;font-size:9.30pt"&gt;space under expiring leases on attractive terms, the amount of new construction in a particular area, the laws and &lt;/span&gt;&lt;span style="color:#000000;font-family:arial;font-size:9.30pt"&gt;regulations (including zoning, environmental and tax laws) affecting real estate and the costs of owning, maintaining &lt;/span&gt;&lt;span style="color:#000000;font-family:arial;font-size:9.30pt"&gt;and improving real estate. The availability of mortgage financing and changes in interest rates may also affect real &lt;/span&gt;&lt;span style="color:#000000;font-family:arial;font-size:9.30pt"&gt;estate values. If the Fund&#x2019;s real estate-related investments are concentrated in one geographic area or in one &lt;/span&gt;&lt;span style="color:#000000;font-family:arial;font-size:9.30pt"&gt;property type, the Fund will be particularly subject to the risks associated with that area or property type. Many &lt;/span&gt;&lt;span style="color:#000000;font-family:arial;font-size:9.30pt"&gt;issuers of real estate-related securities are highly leveraged, which increases the risk to holders of such securities. &lt;/span&gt;&lt;span style="color:#000000;font-family:arial;font-size:9.30pt"&gt;The value of the securities the Fund buys will not necessarily track the value of the underlying investments of the &lt;/span&gt;&lt;span style="color:#000000;font-family:arial;font-size:9.30pt"&gt;issuers of such securities. In addition, certain issuers of real estate-related securities may have developed or &lt;/span&gt;&lt;span style="color:#000000;font-family:arial;font-size:9.30pt"&gt;commenced development on properties and may develop additional properties in the future. Real estate &lt;/span&gt;&lt;span style="color:#000000;font-family:arial;font-size:9.30pt"&gt;development involves significant risks in addition to those involved in the ownership and operation of established &lt;/span&gt;&lt;span style="color:#000000;font-family:arial;font-size:9.30pt"&gt;properties. Real estate securities may have limited diversification and are, therefore, subject to risks inherent in &lt;/span&gt;&lt;span style="color:#000000;font-family:arial;font-size:9.30pt"&gt;operating and financing a limited number of projects. Real estate securities are also subject to heavy cash flow &lt;/span&gt;&lt;span style="color:#000000;font-family:arial;font-size:9.30pt"&gt;dependency and defaults by borrowers or tenants.&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>

In April 2023, however, the FCA announced that some USD LIBOR settings would continue to be published &lt;/span&gt;&lt;span style="color:#000000;font-family:arial;font-size:9.30pt"&gt;under a synthetic methodology until September 30, 2024 for certain legacy contracts. After September 30, 2024, &lt;/span&gt;&lt;span style="color:#000000;font-family:arial;font-size:9.30pt"&gt;the remaining synthetic LIBOR settings ceased to be published, and all LIBOR settings have permanently ceased. &lt;/span&gt;&lt;span style="color:#000000;font-family:arial;font-size:9.30pt"&gt;The Secured Overnight Financing Rate (&#x201c;SOFR&#x201d;) is a broad measure of the cost of borrowing cash overnight &lt;/span&gt;&lt;span style="color:#000000;font-family:arial;font-size:9.30pt"&gt;collateralized by U.S. Treasury securities in the repurchase agreement (&#x201c;repo&#x201d;) market and has been used &lt;/span&gt;&lt;span style="color:#000000;font-family:arial;font-size:9.30pt"&gt;increasingly on a voluntary basis in new instruments and transactions. Under U.S. regulations that implement a &lt;/span&gt;&lt;span style="color:#000000;font-family:arial;font-size:9.30pt"&gt;statutory fallback mechanism to replace LIBOR, benchmark rates based on SOFR have replaced LIBOR in certain &lt;/span&gt;&lt;span style="color:#000000;font-family:arial;font-size:9.30pt"&gt;financial contracts.&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;Neither the effect of the LIBOR transition process nor its ultimate success can yet be known. While some existing &lt;/span&gt;&lt;span style="color:#000000;font-family:arial;font-size:9.30pt"&gt;LIBOR-based instruments may contemplate a scenario where LIBOR is no longer available by providing for an &lt;/span&gt;&lt;span style="color:#000000;font-family:arial;font-size:9.30pt"&gt;alternative rate-setting methodology, there may be significant uncertainty regarding the effectiveness of any such &lt;/span&gt;&lt;span style="color:#000000;font-family:arial;font-size:9.30pt"&gt;alternative methodologies to replicate LIBOR. Not all existing LIBOR-based instruments may have alternative rate-setting&lt;/span&gt;&lt;span style="color:#000000;font-family:arial;font-size:9.30pt"&gt; provisions and there remains uncertainty regarding the willingness and ability of issuers to add alternative &lt;/span&gt;&lt;span style="color:#000000;font-family:arial;font-size:9.30pt"&gt;rate-setting provisions in certain existing instruments.

An economic downturn generally leads to a higher non-payment rate, and a senior &lt;/span&gt;&lt;span style="color:#000000;font-family:arial;font-size:9.30pt"&gt;loan may lose significant value before a default occurs. Moreover, any specific collateral used to secure a senior &lt;/span&gt;&lt;span style="color:#000000;font-family:arial;font-size:9.30pt"&gt;loan may decline in value or become illiquid, which would adversely affect the senior loan&#x2019;s value. No active trading &lt;/span&gt;&lt;span style="color:#000000;font-family:arial;font-size:9.30pt"&gt;market may exist for certain senior loans, which may impair the ability of the Fund to realize full value in the event &lt;/span&gt;&lt;span style="color:#000000;font-family:arial;font-size:9.30pt"&gt;of the need to sell a senior loan and which may make it difficult to value senior loans. Although senior loans in &lt;/span&gt;&lt;span style="color:#000000;font-family:arial;font-size:9.30pt"&gt;which the Fund will invest generally will be secured by specific collateral, there can be no assurance that liquidation &lt;/span&gt;&lt;span style="color:#000000;font-family:arial;font-size:9.30pt"&gt;of such collateral would satisfy the borrower&#x2019;s obligation in the event of non-payment of scheduled interest or &lt;/span&gt;&lt;span style="color:#000000;font-family:arial;font-size:9.30pt"&gt;principal or that such collateral could be readily liquidated. To the extent that a senior loan is collateralized by stock &lt;/span&gt;&lt;span style="color:#000000;font-family:arial;font-size:9.30pt"&gt;in the borrower or its subsidiaries, such stock may lose all of its value in the event of the bankruptcy of the &lt;/span&gt;&lt;span style="color:#000000;font-family:arial;font-size:9.30pt"&gt;borrower.

The per share net asset value of an ETF is calculated at &lt;/span&gt;&lt;span style="color:#000000;font-family:arial;font-size:9.30pt"&gt;the end of each business day and fluctuates with changes in the market value of the ETF&#x2019;s holdings since the most &lt;/span&gt;&lt;span style="color:#000000;font-family:arial;font-size:9.30pt"&gt;recent calculation. The trading prices of an ETF&#x2019;s shares fluctuate continuously throughout trading hours based on &lt;/span&gt;&lt;span style="color:#000000;font-family:arial;font-size:9.30pt"&gt;market supply and demand rather than net asset value. The trading prices of an ETF&#x2019;s shares may deviate &lt;/span&gt;&lt;span style="color:#000000;font-family:arial;font-size:9.30pt"&gt;significantly from net asset value during periods of market volatility. Any of these factors may lead to an ETF&#x2019;s &lt;/span&gt;&lt;span style="color:#000000;font-family:arial;font-size:9.30pt"&gt;shares trading at a premium or discount to net asset value.

While the creation/redemption feature is designed to make it likely that an ETF&#x2019;s &lt;/span&gt;&lt;span style="color:#000000;font-family:arial;font-size:9.30pt"&gt;shares normally trade on exchanges at prices close to the ETF&#x2019;s next calculated net asset value, exchange prices &lt;/span&gt;&lt;span style="color:#000000;font-family:arial;font-size:9.30pt"&gt;are not expected to correlate exactly with an ETF&#x2019;s net asset value due to timing reasons as well as market supply &lt;/span&gt;&lt;span style="color:#000000;font-family:arial;font-size:9.30pt"&gt;and demand factors. In addition, disruptions to creations and redemptions or the existence of extreme market &lt;/span&gt;&lt;span style="color:#000000;font-family:arial;font-size:9.30pt"&gt;volatility may result in trading prices that differ significantly from net asset value. If a shareholder purchases at a &lt;/span&gt;&lt;span style="color:#000000;font-family:arial;font-size:9.30pt"&gt;time when the market price is at a premium to the net asset value or sells at a time when the market price is at a &lt;/span&gt;&lt;span style="color:#000000;font-family:arial;font-size:9.30pt"&gt;discount to the net asset value, the shareholder may sustain losses. The use of cash creations and redemptions &lt;/span&gt;&lt;span style="color:#000000;font-family:arial;font-size:9.30pt"&gt;may also cause the ETFs&#x2019; shares to trade in the market at greater bid-ask spreads or greater premiums or &lt;/span&gt;&lt;span style="color:#000000;font-family:arial;font-size:9.30pt"&gt;discounts to the ETFs&#x2019; NAV.&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>

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;</oef:RiskTextBlock>

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.</link:footnote>
