The Sub-Advisor continually reviews fundamental economic and structural themes that impact long and medium term asset returns in emerging markets. The Sub-Advisor also considers shorter term market drivers such as valuations, liquidity conditions and sentiment to determine the appropriate positioning of the Fund&#x2019;s investments. The Sub-Advisor will adjust the portfolio&#x2019;s country allocations, duration and individual security positioning to reflect what it believes to be the most attractive &lt;/span&gt;&lt;span style="color:#000000;font-family:Arial;font-size:9.00pt;"&gt;opportunities on a continuous basis.  &lt;/span&gt;&lt;span style="font-family:Arial;font-size:9.00pt;margin-left:0%;"&gt;The Sub-Advisor considers emerging market countries to be countries that are characterized by developing commercial and financial infrastructure with significant potential for economic growth and increased capital market participation by foreign investors. The Sub-Advisor considers a variety of factors when determining whether a country should be considered an emerging market, including whether it is classified by the World Bank in the lower, lower-middle or upper-middle income designation for one of the past three years. As of the date of this prospectus, the Sub-Advisor considers emerging market countries to include any country other than Canada, the United States, Australia, Austria, Belgium, Cyprus, Denmark, Finland, France, Germany, Hong Kong, Iceland, Ireland, Italy, Japan, Luxembourg, the Netherlands, New Zealand, Norway, Portugal, Singapore, Spain, Sweden, Switzerland and the United Kingdom. This list of emerging market countries may be expanded or exceptions may be made depending on the evolution of market and economic conditions. The Fund&#x2019;s exposure to any single country generally will be limited to 20% of the Fund&#x2019;s net assets, although this percentage may change from time to time in response to economic events. The percentage of Fund assets invested in a specific region, country or issuer will change from time to time. &lt;/span&gt;&lt;span style="font-family:Arial;font-size:9.00pt;"&gt;As of January 30, 2026, the Fund had significant investments in Asian issuers and in Latin America issuers, and &lt;/span&gt;&lt;span style="font-family:Arial;font-size:9.00pt;margin-left:0%;"&gt;may be expected to invest significantly in European issuers although this may change from time to time.&lt;/span&gt;&lt;span style="font-family:Arial;font-size:9.00pt;"&gt;Over time, the Fund &lt;/span&gt;&lt;span style="font-family:Arial;font-size:9.00pt;margin-left:0%;"&gt;may have significant investments in a jurisdiction, investment sector or industry or group of industries that it may not have had as of January&lt;/span&gt;&lt;span style="font-family:Arial;font-size:9.00pt;"&gt; 30, 2026. To the extent the Fund invests a significant portion of its assets in a given jurisdiction,&lt;/span&gt;&lt;span style="font-family:Arial;font-size:9.00pt;line-height:10.80pt;"&gt;  &lt;/span&gt;&lt;span style="font-family:Arial;font-size:9.00pt;"&gt;investment &lt;/span&gt;&lt;span style="font-family:Arial;font-size:9.00pt;margin-left:0%;"&gt;sector&lt;/span&gt;&lt;span style="font-family:Arial;font-size:9.00pt;"&gt; or industry or group of industries, the Fund may be exposed to the risks associated with that jurisdiction,&lt;/span&gt;&lt;span style="font-family:Arial;font-size:9.00pt;line-height:10.80pt;"&gt;  &lt;/span&gt;&lt;span style="font-family:Arial;font-size:9.00pt;"&gt;investment sector or industry or group of industries.  &lt;/span&gt;&lt;span style="color:#000000;font-family:Arial;font-size:9.00pt;margin-left:0%;"&gt;The Fund may invest in Bonds of any credit quality, including unrated securities, high-yield (also known as &#x201c;junk&#x201d;) bonds, and with effective or final maturities of any length. The Fund will invest only in Bonds that, at the time of purchase, are performing, and not in default or distressed. However, the Fund may invest in Bonds which become non-performing, distressed or defaulted subsequent to purchase and the Fund may continue to hold such Bonds. Under normal market conditions, at least 80% of the Fund&#x2019;s net assets that are invested in Bonds will be invested in Bonds that are issued by issuers with outstanding debt of &lt;/span&gt;&lt;span style="color:#000000;font-family:Arial;font-size:9.00pt;"&gt;at least $200 million, or the foreign currency equivalent thereof.  &lt;/span&gt;&lt;span style="color:#000000;font-family:Arial;font-size:9.00pt;margin-left:0%;"&gt;The Fund may invest in foreign currencies and derivative instruments, including swap agreements, exchange-listed futures contracts, exchange-listed options, exchange-listed options on futures contracts, forward currency contracts, non-deliverable forward currency contracts and exchange-listed currency options. The Fund uses foreign currencies and derivative instruments primarily to hedge interest rate risk and actively manage interest rate exposure and to hedge foreign currency risk and actively manage foreign currency exposure. The Fund may also use derivative instruments to enhance returns, as a substitute for, or to gain exposure to, a position in an underlying asset, to reduce transaction costs, to maintain full market exposure, to manage cash flows or to preserve capital. The Fund&#x2019;s investments in derivative instruments will not be used to seek to achieve a multiple or inverse multiple of an index. Under normal market conditions, no more than 20% of the value of the Fund&#x2019;s net assets will be invested in derivative instruments. To the extent that the Fund invests in derivative instruments as a substitute for, or to gain exposure to, a position in an underlying asset, such investments shall be (a) counted towards the 80% test set forth &lt;/span&gt;&lt;span style="color:#000000;font-family:Arial;font-size:9.00pt;"&gt;above and valued according to their market, and not notional, value.  &lt;/span&gt;&lt;span style="color:#000000;font-family:Arial;font-size:9.00pt;"&gt;The Fund is classified as &#x201c;non-diversified&#x201d; under the Investment Company Act of 1940, as amended (the &lt;/span&gt;&lt;span style="color:#000000;font-family:Arial;font-size:9.00pt;font-style:italic;"&gt;&#x201c;1940 Act&#x201d;&lt;/span&gt;&lt;span style="color:#000000;font-family:Arial;font-size:9.00pt;"&gt;).&lt;/span&gt;</oef:StrategyNarrativeTextBlock>

Many &lt;/span&gt;&lt;span style="color:#000000;font-family:Arial;font-size:9.00pt;margin-left:0%;"&gt;Asian economies have experienced rapid growth and industrialization, and there is no assurance that this growth rate will be maintained. Some Asian economies are highly dependent on trade, and economic conditions in other countries within and outside Asia can impact these economies. Certain of these economies may be adversely affected by trade or policy disputes &lt;/span&gt;&lt;span style="color:#000000;font-family:Arial;font-size:9.00pt;margin-left:0%;"&gt;with its major trade partners. There is also a high concentration of market capitalization and trading volume in a small number of issuers representing a limited number of industries, as well as a high concentration of investors and financial intermediaries. Certain Asian countries have experienced and may in the future experience expropriation and nationalization of assets, confiscatory taxation, currency manipulation, political instability, armed conflict and social instability as a result of religious, ethnic, socio-economic and/or political unrest. In particular, escalated tensions involving North Korea and any outbreak of hostilities involving North Korea could have a severe adverse effect on Asian economies. Governments of certain Asian countries have exercised, and continue to exercise, substantial influence over many aspects of the private sector. In certain cases, the government owns or controls many companies, including the largest in the country. Accordingly, government actions could have a significant effect on the issuers of the Fund&#x2019;s securities or on economic conditions generally. Recent developments in relations between the U.S. and China have heightened concerns of increased tariffs and restrictions on trade between the two countries. An increase in tariffs or trade restrictions, or even the threat of such developments, could lead to a significant reduction in international trade, which could have a negative impact on the economy of Asian countries and a commensurately &lt;/span&gt;&lt;span style="color:#000000;font-family:Arial;font-size:9.00pt;"&gt;negative impact on the Fund.&lt;/span&gt;</oef:RiskTextBlock>

The Fund is subject to the possibility that during periods of falling interest rates an issuer will call its high yielding debt securities.

U.S. regulators have proposed several changes to market and issuer regulations which would directly impact the Fund, and any regulatory changes could adversely impact the Fund&#x2019;s ability to achieve its investment strategies or make certain investments. &lt;/span&gt;&lt;span style="font-family:Arial;font-size:9.00pt;"&gt;Potential future bank failures could result in disruption to the broader banking industry or markets &lt;/span&gt;&lt;span style="font-family:Arial;font-size:9.00pt;margin-left:0%;"&gt;generally and reduce confidence in financial institutions and the economy as a whole, which may also heighten market volatility and reduce liquidity. Additionally, challenges in commercial real estate markets, including &lt;/span&gt;&lt;span style="font-family:Arial;font-size:9.00pt;"&gt;high interest rates, declining valuations &lt;/span&gt;&lt;span style="font-family:Arial;font-size:9.00pt;margin-left:0%;"&gt;and &lt;/span&gt;&lt;span style="font-family:Arial;font-size:9.00pt;"&gt;elevated vacancies, could have a broader impact on financial markets. The ongoing adversarial political climate in the &lt;/span&gt;&lt;span style="font-family:Arial;font-size:9.00pt;margin-left:0%;"&gt;United States, as well as political and diplomatic events both domestic and abroad, have and may continue to have an adverse impact the U.S. regulatory landscape, markets and investor behavior, which could have a negative impact on the Fund&#x2019;s investments and operations. The change in administration resulting from the 2024 United States national elections could result in significant impacts to international trade relations, tax and immigration policies, and other aspects of the national and international political and financial landscape, which could affect, among other things, inflation and the securities markets generally. Other unexpected political, regulatory and diplomatic events within the U.S. and abroad may affect investor and consumer confidence and may adversely impact financial markets and the broader economy. For example, ongoing armed conflicts between Russia and Ukraine in Europe and among Israel, Iran, Hamas and other militant groups in the Middle East, have caused and could continue to cause significant market disruptions and volatility within the markets in Russia, Europe, the Middle East and the United States. The hostilities and sanctions resulting from those hostilities have and could continue to have a significant impact on certain Fund investments as well as Fund performance and liquidity. The economies of the United States and its trading partners, as well as the financial markets generally, may be adversely impacted by trade disputes&lt;/span&gt;&lt;span style="font-family:Arial;font-size:9.00pt;"&gt;,  &lt;/span&gt;&lt;span style="font-family:Arial;font-size:9.00pt;margin-left:0%;"&gt;including the imposition of tariffs,&lt;/span&gt;&lt;span style="font-family:Arial;font-size:9.00pt;"&gt; and other matters. For example, the United States has imposed trade barriers and restrictions &lt;/span&gt;&lt;span style="font-family:Arial;font-size:9.00pt;margin-left:0%;"&gt;on China. In addition, the Chinese government is engaged in a longstanding dispute with Taiwan, continually threatening an invasion. If the political climate between the United States and China does not improve or continues to deteriorate, if China were to attempt invading Taiwan, or if other geopolitical conflicts develop or worsen, economies, markets and individual securities may be adversely affected, and the value of the Fund&#x2019;s assets may go down. A public health crisis and the ensuing policies enacted by governments and central banks may cause significant volatility and uncertainty in global financial markets, negatively impacting global growth prospects. As the COVID-19 global pandemic illustrated, such events may affect certain geographic regions, countries, sectors and industries more significantly than others. Advancements in technology may also adversely impact markets and the overall performance of the Fund. For instance, the economy may be significantly impacted by the advanced development and increased regulation of artificial intelligence. Additionally, cyber security breaches of both government and non-government entities could have negative impacts on infrastructure and the ability of such entities, including the Fund, to operate properly. These events, and any other future events, may adversely affect the prices and liquidity &lt;/span&gt;&lt;span style="font-family:Arial;font-size:9.00pt;"&gt;of the Fund&#x2019;s portfolio investments and could result in disruptions in the trading markets.&lt;/span&gt;</oef:RiskTextBlock>

Cyber security incidents affecting issuers in whose securities the Fund invests may also have a negative impact on the value of the securities of such issuers, and in turn, the value of the &lt;/span&gt;&lt;span style="font-family:Arial;font-size:9.00pt;"&gt;Fund.&lt;/span&gt;</oef:RiskTextBlock>

Credit risk refers to &lt;/span&gt;&lt;span style="font-family:Arial;font-size:9.00pt;margin-left:0%;"&gt;the possibility that the issuer or other obligor of a security will not be able or willing to make payments of interest and principal when due. Generally, the value of debt securities will change inversely with changes in interest rates. To the extent that interest rates rise, certain underlying obligations may be paid off substantially slower than originally anticipated and the value of those securities may fall sharply. During periods of falling interest rates, the income received by the Fund may decline. If the principal on a debt security is prepaid before expected, the prepayments of principal may have to be reinvested in obligations paying interest at lower rates. Debt securities generally do not trade on a securities exchange making them generally less liquid and more difficult to value than common stock.&lt;/span&gt;&lt;span style="font-family:Arial;font-size:9.00pt;"&gt; Debt securities held by the Fund may be subject to amendments, waivers, or &lt;/span&gt;&lt;span style="font-family:Arial;font-size:9.00pt;margin-left:0%;"&gt;exchange offers that modify their terms. These transactions may be initiated by borrowers to address financial stress and may include exchanges of existing debt securities for new instruments with different priority, collateral, or economic characteristics. Participation in, or exclusion from, such transactions could result in the Fund holding debt that is structurally or contractually &lt;/span&gt;&lt;span style="font-family:Arial;font-size:9.00pt;"&gt;subordinated, less liquid, or of lower market value than prior to the transaction.&lt;/span&gt;</oef:RiskTextBlock>

These risks include or may include: (i) the risk that the value of the underlying assets may go up or down; (ii) the risk that the counterparty to a derivative transaction may not fulfill its contractual obligations; (iii) the risk of mispricing or improper valuation of a derivative; (iv) the risk that changes in the value of the derivative may not correlate perfectly with the underlying asset; (v) the risk that a derivative instrument cannot be sold, closed out or replaced quickly at or very close to its fundamental value; (vi) the risk of loss caused by the unenforceability of a party&#x2019;s obligations under the derivative; and (vii) the risk that a disruption in the financial markets will cause difficulties for all market participants. Derivative prices are highly volatile and may fluctuate substantially during a short period of time. Such prices are influenced by numerous factors that affect the markets, including, but not limited to: changing supply and demand relationships; government programs and policies; national and international political and economic events, changes in interest rates, inflation and deflation and changes in supply and demand relationships. Trading derivative instruments involves risks different from, or possibly greater than, the risks associated with investing directly in securities. Derivative contracts ordinarily have leverage inherent in their terms. The low margin deposits normally required in trading derivatives, including futures contracts, permit a high degree of leverage. Accordingly, a relatively small price movement may result in an immediate and substantial loss. The use of leverage may also cause the Fund to liquidate portfolio positions when it would not be advantageous to do so. The use of leveraged derivatives can magnify potential for gain or loss and, therefore, amplify the &lt;/span&gt;&lt;span style="color:#000000;font-family:Arial;font-size:9.00pt;"&gt;effects of market volatility on share price.&lt;/span&gt;</oef:RiskTextBlock>

Investments in emerging markets securities are generally considered speculative in nature and are subject to the following heightened risks: smaller market capitalization of securities markets which may suffer periods of relative illiquidity; significant price volatility; restrictions on foreign investment; possible repatriation of investment income and capital; rapid inflation; and currency convertibility issues. Emerging market countries also often have less uniformity in accounting, auditing and reporting requirements, unsettled securities laws, unreliable securities valuation and greater risk associated with custody of securities. Financial and other reporting by companies and government entities also may be less reliable in emerging market countries. Shareholder claims that are available in the U.S., as well as regulatory oversight and authority that is common in the U.S., including for claims based on fraud, may be difficult or impossible for shareholders of securities in emerging market countries or for U.S. authorities to pursue. For funds that track an index or are managed based upon a benchmark, the index may not weight the securities in emerging market countries on the basis of investor protection limitations, financial reporting quality or available oversight mechanisms. Furthermore, investors may be required to register the proceeds of sales and future economic or political crises could lead to price controls, forced mergers, expropriation or confiscatory taxation, seizure, &lt;/span&gt;&lt;span style="color:#000000;font-family:Arial;font-size:9.00pt;"&gt;nationalization or creation of government monopolies.&lt;/span&gt;</oef:RiskTextBlock>

Political or economic disruptions in European countries, even in countries in which the Fund is not invested, may adversely affect security values and thus the Fund&#x2019;s holdings. A significant number of countries in Europe are member states in the European Union (the &lt;/span&gt;&lt;span style="color:#000000;font-family:Arial;font-size:9.00pt;font-style:italic;"&gt;&#x201c;EU&#x201d;&lt;/span&gt;&lt;span style="color:#000000;font-family:Arial;font-size:9.00pt;"&gt;), and the member states no longer control their own &lt;/span&gt;&lt;span style="color:#000000;font-family:Arial;font-size:9.00pt;margin-left:0%;"&gt;monetary policies by directing independent interest rates for their currencies. In these member states, the authority to direct monetary policies, including money supply and official interest rates for the Euro, is exercised by the European Central Bank. In a 2016 referendum, the United Kingdom elected to withdraw from the EU (&lt;/span&gt;&lt;span style="color:#000000;font-family:Arial;font-size:9.00pt;font-style:italic;"&gt;&#x201c;Brexit&#x201d;&lt;/span&gt;&lt;span style="color:#000000;font-family:Arial;font-size:9.00pt;"&gt;). After years of negotiations between &lt;/span&gt;&lt;span style="color:#000000;font-family:Arial;font-size:9.00pt;margin-left:0%;"&gt;the United Kingdom and the EU, a withdrawal agreement was reached whereby the United Kingdom formally left the EU. As the second largest economy among EU members, the implications of the United Kingdom&#x2019;s withdrawal are difficult to gauge and cannot be fully known. Its departure may negatively impact the EU and Europe as a whole by causing volatility within the EU, triggering prolonged economic downturns in certain European countries or sparking additional member states to &lt;/span&gt;&lt;span style="color:#000000;font-family:Arial;font-size:9.00pt;"&gt;contemplate departing the EU (thereby perpetuating political instability in the region).&lt;/span&gt;</oef:RiskTextBlock>

A relatively small price movement in a forward contract may result in substantial losses to the Fund, exceeding the amount of the margin paid. Forward contracts can increase the Fund&#x2019;s risk exposure to underlying references and their attendant risks, such as credit risk, currency risk, market risk, and interest rate risk, while also exposing the Fund to counterparty risk, liquidity risk and &lt;/span&gt;&lt;span style="color:#000000;font-family:Arial;font-size:9.00pt;"&gt;valuation risk, among others.&lt;/span&gt;</oef:RiskTextBlock>

There are no limitations on daily price moves in such forward contracts, and banks and dealers are not required to continue to make markets in such contracts. There have been periods during which certain banks or dealers have refused to quote prices for such forward contracts or have quoted prices with an unusually wide spread between the price at which the bank or dealer is prepared to buy and that at which it is prepared to sell. Governmental imposition of credit controls might limit any such forward contract trading. Forward foreign currency exchange contracts involve certain risks, including the risk of failure of the counterparty to perform its obligations under the contract and the risk that the use of forward contracts may not serve as a complete hedge because of an imperfect correlation between movements in the prices of the contracts and the prices of the currencies hedged. Forward foreign currency exchange contracts may limit any potential gain that might result should the value of the underlying currencies increase. In addition, because forward currency exchange contracts are privately negotiated transactions, there can be no assurance that the Fund &lt;/span&gt;&lt;span style="color:#000000;font-family:Arial;font-size:9.00pt;"&gt;will have flexibility to roll-over a forward foreign currency exchange contract upon its expiration if it desires to do so.&lt;/span&gt;</oef:RiskTextBlock>

The risk of a position in a futures contract may be very large compared to the relatively low level of margin the Fund is required to deposit. In many cases, a relatively small price movement in a futures contract may result in immediate and substantial loss or gain to the investor relative to the size of a required margin deposit. In the event no secondary market exists for a particular contract, it might not be possible to effect closing transactions, and the Fund will be unable to terminate the derivative. If the Fund uses futures contracts for hedging purposes, there is a risk of imperfect correlation between movements in the prices of the derivatives and movements in the securities or index underlying the derivatives or movements in the prices of the Fund's investments that are the subject of such hedge.

Interest rate risk is generally lower for shorter term debt securities and higher for longer-term debt securities. The Fund may be subject to a greater risk of rising interest rates than would normally be the case during periods of low interest rates. Duration is a reasonably accurate measure of a debt security&#x2019;s price sensitivity to changes in interest rates and a common measure of interest rate risk. Duration measures a debt security&#x2019;s expected life on a present value basis, taking into account the debt security&#x2019;s yield, interest payments and final maturity. In general, duration represents the expected percentage change in the value of a security for an immediate 1% change in interest rates. For example, the price of a debt security with a three-year duration would be expected to drop by approximately 3% in response to a 1% increase in interest rates. Therefore, prices of debt securities with shorter durations tend to be less sensitive to interest rate changes than debt securities with longer durations. Higher sensitivity to interest rates is generally correlated with higher levels of &lt;/span&gt;&lt;span style="color:#000000;font-family:Arial;font-size:9.00pt;"&gt;volatility and, therefore, greater risk. As the value of a debt security changes over time, so will its duration.&lt;/span&gt;</oef:RiskTextBlock>

The economies of Latin American countries have in the past experienced considerable difficulties, including high inflation rates, high interest rates, high unemployment, government overspending and political instability. International economic conditions, particularly those in the United States, Europe and Asia, as well as world prices for oil and other commodities may also influence the development of Latin American economies. Many Latin American countries are highly reliant on the exportation of commodities and their economies may be significantly impacted by fluctuations in commodity prices and the global demand for certain commodities. Investments in Latin American countries may be subject to currency risks, such as restrictions on the flow of money in and out of a country, extreme volatility relative to the U.S. dollar, and devaluation, all of which could decrease the value of investments in Latin American companies. Other Latin American investment risks may include inadequate investor protection, less developed regulatory, accounting, auditing and financial standards, unfavorable changes in laws or regulations, natural disasters, corruption and military activity. The governments of many Latin American countries may also exercise substantial influence over many aspects of the private sector, and any such exercise could have a significant effect on companies in which the Fund invests. Securities of companies in Latin America may also be &lt;/span&gt;&lt;span style="color:#000000;font-family:Arial;font-size:9.00pt;"&gt;subject to significant price volatility.&lt;/span&gt;</oef:RiskTextBlock>

The Fund&#x2019;s investment advisor cannot predict whether shares will trade below, at or above their net asset value because the shares trade on the Exchange at market prices and not at net asset value. Price differences may be due, in large part, to the fact that supply and demand forces at work in the secondary trading market for shares will be closely related, but not identical, to the same forces influencing the prices of the holdings of the Fund trading individually or in the aggregate at any point in time. However, given that shares can only be purchased and redeemed in Creation Units, and only to and from broker-dealers and large institutional investors that have entered into participation agreements (unlike shares of closed-end funds, which frequently trade at appreciable discounts from, and sometimes at premiums to, their net asset value), the Fund&#x2019;s investment advisor believes that large discounts or premiums to the net asset value of shares should not be sustained. During stressed market conditions, the market for the Fund&#x2019;s shares may become less liquid in response to deteriorating liquidity in the market for the Fund&#x2019;s underlying portfolio holdings, which could in turn lead to differences between the market price of the Fund&#x2019;s shares and their net asset &lt;/span&gt;&lt;span style="color:#000000;font-family:Arial;font-size:9.00pt;"&gt;value and the bid/ask spread on the Fund&#x2019;s shares may widen.&lt;/span&gt;</oef:RiskTextBlock>

Unlike publicly traded securities that trade on national securities exchanges, there is no central place or exchange for trading most debt securities. Debt securities generally trade on an &#x201c;over-the-counter&#x201d; market. Due to the lack of centralized information and trading, and variations in lot sizes of certain debt securities, the valuation of debt securities may carry more uncertainty and risk than that of publicly traded securities. Debt securities are commonly valued by third-party pricing services that utilize a range of market-based inputs and assumptions, including readily available market quotations obtained from broker-dealers making markets in such securities, cash flows and transactions for comparable instruments. However, because the available information is less reliable and more subjective, elements of judgment may play a greater role in valuation of debt securities than for other types of securities. Different pricing services may incorporate different assumptions and inputs into their valuation methodologies, potentially resulting in different values for the same securities. As a result, if the Advisor were to change its valuation policies, or if the Fund were to change pricing services, or if a pricing service were to change its valuation methodology, there could be a material impact, either positive or negative, on the Fund&#x2019;s net asset value. Additionally, pricing services generally price debt securities assuming orderly transactions of an institutional &#x201c;round lot&#x201d; size, but some trades may occur in smaller, &#x201c;odd lot&#x201d; sizes, often at lower prices than institutional round lot trades. There is no assurance that the Fund will be able to sell a portfolio security at the price established by the pricing service, which could result in a loss to the Fund. In addition, the value of the debt securities in the Fund's portfolio may change on days or during time periods when shareholders will not be able to purchase or sell the Fund's shares. Authorized Participants who purchase or redeem Fund shares on days when the Fund is holding fair-valued securities may receive fewer or more shares, or lower or higher redemption proceeds, than they would have received had the Fund not fair-valued securities or used a different valuation methodology. Net asset &lt;/span&gt;&lt;span style="color:#000000;font-family:Arial;font-size:9.00pt;"&gt;value calculation may also be impacted by operational risks arising from factors such as failures in systems and technology.  &lt;/span&gt;&lt;span style="font-family:Arial;font-size:9.00pt;margin-left:0%;"&gt;The Fund may hold securities or other assets that may be valued on the basis of factors other than market quotations. This may occur because the asset or security does not trade on a centralized exchange, or in times of market turmoil or reduced liquidity. There are multiple methods that can be used to value a portfolio holding when market quotations are not readily available. Fund investments that trade on non-U.S. exchanges that close prior to the close of the NYSE may be fair valued using a systematic fair valuation model. If these foreign investments meet certain criteria in relation to the valuation model, their valuation is systematically adjusted to reflect the impact of movement in the U.S. market after the close of certain foreign markets. The value established for any portfolio holding at a point in time might differ from what would be produced using a different methodology or if it had been priced using market quotations. In addition, there is no assurance that the Fund could sell or close out a portfolio position for the value established for it at any time, and it is possible that the Fund would incur a loss because a portfolio position is sold or closed out at a discount to the valuation established by the Fund at that time. The Fund&#x2019;s ability to value investments may be impacted by technological issues or errors by pricing services or other &lt;/span&gt;&lt;span style="font-family:Arial;font-size:9.00pt;"&gt;third-party service providers.&lt;/span&gt;</oef:RiskTextBlock>

Preferred securities are a type &lt;/span&gt;&lt;span style="color:#000000;font-family:Arial;font-size:9.00pt;margin-left:0%;"&gt;of equity security that have preference over common stock in the payment of distributions and the liquidation of a company&#x2019;s assets, but are generally junior to all forms of the company&#x2019;s debt, including both senior and subordinated debt. The Fund&#x2019;s investments in preferred securities will primarily be in institutional preferred securities. Institutional preferred securities are targeted to institutional, rather than retail, investors, are generally traded over-the-counter and may also be known as &#x201c;$1,000 par preferred securities.&#x201d; They are typically issued in large, institutional lot sizes by U.S. and non-U.S. financial services companies and other companies. While all income-producing debt securities will be categorized as &#x201c;Income Securities&#x201d; for purposes of the 80% test above, the Income Securities in which the Fund intends to invest as part of its principal investment strategy include hybrid capital securities, contingent capital securities, U.S. and non-U.S. corporate bonds and convertible securities.  &lt;/span&gt;&lt;span style="color:#000000;font-family:Arial;font-size:9.00pt;margin-left:0%;"&gt;In selecting securities for the Fund, the investment strategy of the Fund&#x2019;s sub-advisor is driven by comprehensive analysis of institutional preferred securities and Income Securities with a goal of investing in securities representing the best relative value in the market. The style of active management by the Fund&#x2019;s sub-advisor combines a bottom-up and top-down approach to security selection that encompasses three significant areas of analysis: credit fundamentals; relative value; and technical aspects of the securities, which may include, but are not limited to, interest rate sensitivity, call features, maturities, trading volumes, liquidity and pricing inefficiencies. The bottom-up analysis focuses on individual security analysis, idiosyncratic risks, credit fundamentals and opportunistic trading. The top-down analysis focuses on sector and industry analysis, duration and &lt;/span&gt;&lt;span style="color:#000000;font-family:Arial;font-size:9.00pt;"&gt;interest rate analysis, capital structure positioning and systemic risks.  &lt;/span&gt;&lt;span style="color:#000000;font-family:Arial;font-size:9.00pt;margin-left:0%;"&gt;In general, the preferred securities held by the Fund are expected to be issued by companies in the financial, communications, consumer, government, utilities, energy, materials, industrial and technology sectors. However, because the issuers of institutional preferred securities are often financial companies, the Fund concentrates its investments by investing at least 25% of its total assets in the group of industries that comprise the financial sector, which includes banks, thrifts, brokerage firms, broker-dealers, investment banks, finance companies and companies involved in the insurance industry. Although the Fund may invest in individual issues of institutional preferred securities with market capitalizations as low as $50 million, the Fund generally does not invest in individual issues of institutional preferred securities if the issuer has a total market capitalization of less than $500 million. The Fund may also invest in preferred securities issued by real estate investment trusts &lt;/span&gt;&lt;span style="color:#000000;font-family:Arial;font-size:9.00pt;"&gt;(&lt;/span&gt;&lt;span style="color:#000000;font-family:Arial;font-size:9.00pt;font-style:italic;"&gt;&#x201c;REITs&#x201d;&lt;/span&gt;&lt;span style="color:#000000;font-family:Arial;font-size:9.00pt;"&gt;).  &lt;/span&gt;&lt;span style="color:#000000;font-family:Arial;font-size:9.00pt;margin-left:0%;"&gt;Along with its investments in institutional preferred securities, the Fund may also invest in retail preferred securities. While institutional preferred securities are generally targeted to institutional investors and trade over-the-counter, retail preferred securities are targeted to retail investors and are exchange-traded at single-share prices of $25, $50 or $100. Both the institutional and retail preferred securities held by the Fund generally pay fixed or adjustable-rate distributions to the Fund. Certain preferred securities may be issued by trusts or other special purpose entities created by companies specifically for &lt;/span&gt;&lt;span style="color:#000000;font-family:Arial;font-size:9.00pt;"&gt;the purpose of issuing such securities.  &lt;/span&gt;&lt;span style="color:#000000;font-family:Arial;font-size:9.00pt;margin-left:0%;"&gt;Additionally, the Fund may invest in Income Securities that have certain characteristics similar to preferred securities. These securities include hybrid capital securities, contingent capital securities and other types of securities that resemble preferred securities but that do not have the traditional features described above. Hybrid capital securities possess varying combinations of features of both debt and traditional preferred securities and as such they may constitute senior debt, junior debt or preferred shares in an issuer&#x2019;s capital structure. Contingent convertible securities (&lt;/span&gt;&lt;span style="color:#000000;font-family:Arial;font-size:9.00pt;font-style:italic;"&gt;&#x201c;CoCos&#x201d;&lt;/span&gt;&lt;span style="color:#000000;font-family:Arial;font-size:9.00pt;"&gt;) are issued primarily by non-U.S. financial &lt;/span&gt;&lt;span style="color:#000000;font-family:Arial;font-size:9.00pt;margin-left:0%;"&gt;institutions that have loss absorption mechanisms benefitting the issuer built into their terms. These loss absorption mechanisms may include automatic conversion into the issuer&#x2019;s common stock or an automatic write down of the security&#x2019;s principal amount upon the occurrence of specific triggers. Certain CoCos may be considered to be high-yield securities (a.k.a. "&lt;/span&gt;&lt;span style="color:#000000;font-family:Arial;font-size:9.00pt;font-style:italic;"&gt;junk&lt;/span&gt;&lt;span style="color:#000000;font-family:Arial;font-size:9.00pt;"&gt;" bonds) and, to the extent a CoCo held by the Fund undergoes a write down, the Fund may lose some or all of its original investment in the CoCo.  &lt;/span&gt;&lt;span style="color:#000000;font-family:Arial;font-size:9.00pt;margin-left:0%;"&gt;The Fund may also invest in floating-rate and fixed-to-floating rate securities as well. Floating-rate and fixed-to-floating rate securities may be traditional preferred or hybrid capital securities. Floating-rate securities pay a rate of income that resets periodically based on short and/or longer-term interest rate benchmarks. If the associated interest rate benchmark rises, the coupon offered by the floating-rate security may rise as well, making such securities less sensitive to rising interest rates (or yields). Similarly, a fixed-to-floating rate security may be less price-sensitive to rising interest rates (or yields), because it has a rate of payment that is fixed for a certain period (typically five, ten or thirty years when first issued), after which period a &lt;/span&gt;&lt;span style="color:#000000;font-family:Arial;font-size:9.00pt;"&gt;floating-rate of payment applies.  &lt;/span&gt;&lt;span style="color:#000000;font-family:Arial;font-size:9.00pt;margin-left:0%;"&gt;Additional Income Securities held by the Fund may include corporate bonds and convertible securities. The broad category of corporate debt securities includes debt issued by U.S. and non-U.S. companies of all kinds, including those with small-, mid- and large-capitalizations. Corporate debt may carry fixed or floating rates of interest. The Fund may invest without limitation in, preferred securities, hybrid capital securities and Income Securities rated below investment grade (BB+/Ba1 or lower) at the time of purchase, which are commonly referred to as high yield securities or &#x201c;junk bonds.&#x201d; The Fund may invest in Income &lt;/span&gt;&lt;span style="color:#000000;font-family:Arial;font-size:9.00pt;"&gt;Securities of any duration and does not target an overall duration for its portfolio of Income Securities.  &lt;/span&gt;&lt;span style="color:#000000;font-family:Arial;font-size:9.00pt;margin-left:0%;"&gt;The Fund may invest in U.S. and non-U.S. debt and equity securities that are traded over-the-counter or are listed on an exchange. The Fund may have exposure to certain emerging markets through its investments in non-U.S. securities. The Fund may also hold investments that are denominated in non-U.S. currencies, or in securities that provide exposure to such currencies, currency exchange rates or interest rates denominated in such currencies. The Fund may also invest U.S. &lt;/span&gt;&lt;span style="color:#000000;font-family:Arial;font-size:9.00pt;"&gt;dollar-denominated depositary receipts and U.S. dollar-denominated foreign securities.  &lt;/span&gt;&lt;span style="color:#000000;font-family:Arial;font-size:9.00pt;margin-left:0%;"&gt;The Fund may have significant investments in securities that are offered pursuant Rule 144A under the Securities Act of 1933, as amended (the &lt;/span&gt;&lt;span style="color:#000000;font-family:Arial;font-size:9.00pt;font-style:italic;"&gt;&#x201c;Securities Act&#x201d;&lt;/span&gt;&lt;span style="color:#000000;font-family:Arial;font-size:9.00pt;"&gt;). Rule 144A securities are considered restricted securities because they may not be sold to &lt;/span&gt;&lt;span style="color:#000000;font-family:Arial;font-size:9.00pt;margin-left:0%;"&gt;the general public without an effective registration statement under the Securities Act. Rule 144A is designed to facilitate efficient trading among institutional investors by permitting the sale of certain unregistered securities to qualified institutional buyers. The restriction on public sale may make it more difficult to value such securities, limit the Fund&#x2019;s ability to dispose of them and lower the amount the Fund could realize upon their sale. Because they are not registered, restricted securities may be sold only in a privately negotiated transaction or pursuant to an exemption from registration. To the extent privately placed securities held by the Fund qualify under Rule 144A and an institutional market develops for those securities, the Fund likely will be able to dispose of the securities without registering them under the Securities Act. To the extent that institutional buyers become, for a time, uninterested in purchasing these securities, investing in Rule 144A securities could increase the &lt;/span&gt;&lt;span style="color:#000000;font-family:Arial;font-size:9.00pt;"&gt;level of the Fund&#x2019;s illiquidity.  &lt;/span&gt;&lt;span style="font-family:Arial;font-size:9.00pt;margin-left:0%;"&gt;The Fund will concentrate its investments (&lt;/span&gt;&lt;span style="font-family:Arial;font-size:9.00pt;font-style:italic;"&gt;i.e.&lt;/span&gt;&lt;span style="font-family:Arial;font-size:9.00pt;"&gt;, invest more than 25% of Fund assets) in the group of industries constituting &lt;/span&gt;&lt;span style="font-family:Arial;font-size:9.00pt;margin-left:0%;"&gt;the financial sector.

CoCos are distinct in that they are intended to either convert into equity or have their principal written down upon the occurrence of certain &#x201c;triggers.&#x201d; When an issuer&#x2019;s capital ratio falls below a specified trigger level, or in a regulator&#x2019;s discretion depending on the regulator&#x2019;s judgment about the issuer&#x2019;s solvency prospects, a CoCo may be written down, written off or converted into an equity security. Due to the contingent write-down, write-off and conversion feature, CoCos may have substantially greater risk than other securities in times of &lt;/span&gt;&lt;span style="color:#000000;font-family:Arial;font-size:9.00pt;margin-left:0%;"&gt;financial stress. If the trigger level is breached, the issuer's decision to write down, write off or convert a CoCo may be outside its control, and the Fund may suffer a complete loss on an investment in CoCos with no chance of recovery even if the issuer remains in existence. The value of CoCos is unpredictable and may be influenced by many factors including, without limitation: the creditworthiness of the issuer and/or fluctuations in such issuer's applicable capital ratios; supply and demand for CoCos; general market conditions and available liquidity; and economic, financial and political events that affect the issuer, its particular &lt;/span&gt;&lt;span style="color:#000000;font-family:Arial;font-size:9.00pt;"&gt;market or the financial markets in general.&lt;/span&gt;</oef:RiskTextBlock>

The value of convertible securities may rise and fall with the market value of the underlying stock or, like a debt security, vary with changes in interest rates and the credit quality of the issuer. A convertible security tends to perform more like a stock when the underlying stock price is high relative &lt;/span&gt;&lt;span style="color:#000000;font-family:Arial;font-size:9.00pt;"&gt;to the conversion price and more like a debt security when the underlying stock price is low relative to the conversion price.&lt;/span&gt;</oef:RiskTextBlock>

As a means to fight inflation, &lt;/span&gt;&lt;span style="font-family:Arial;font-size:9.00pt;"&gt;the Federal Reserve and &lt;/span&gt;&lt;span style="font-family:Arial;font-size:9.00pt;margin-left:0%;"&gt;certain foreign central banks have raised interest rates; however, the Federal Reserve has &lt;/span&gt;&lt;span style="font-family:Arial;font-size:9.00pt;"&gt;begun to lower interest rates and &lt;/span&gt;&lt;span style="font-family:Arial;font-size:9.00pt;margin-left:0%;"&gt;may continue to do so. U.S. regulators have proposed several changes to market and issuer regulations which would directly impact the Fund, and any regulatory changes could adversely impact the Fund&#x2019;s ability to achieve its investment strategies or make certain investments. &lt;/span&gt;&lt;span style="font-family:Arial;font-size:9.00pt;"&gt;Potential future bank failures could result in disruption to the broader banking industry or markets &lt;/span&gt;&lt;span style="font-family:Arial;font-size:9.00pt;margin-left:0%;"&gt;generally and reduce confidence in financial institutions and the economy as a whole, which may also heighten market volatility and reduce liquidity. Additionally, challenges in commercial real estate markets, including &lt;/span&gt;&lt;span style="font-family:Arial;font-size:9.00pt;"&gt;high interest rates, declining valuations &lt;/span&gt;&lt;span style="font-family:Arial;font-size:9.00pt;margin-left:0%;"&gt;and &lt;/span&gt;&lt;span style="font-family:Arial;font-size:9.00pt;"&gt;elevated vacancies, could have a broader impact on financial markets. The ongoing adversarial political climate in the &lt;/span&gt;&lt;span style="font-family:Arial;font-size:9.00pt;margin-left:0%;"&gt;United States, as well as political and diplomatic events both domestic and abroad, have and may continue to have an adverse impact the U.S. regulatory landscape, markets and investor behavior, which could have a negative impact on the Fund&#x2019;s investments and operations. The change in administration resulting from the 2024 United States national elections could result in significant impacts to international trade relations, tax and immigration policies, and other aspects of the national and international political and financial landscape, which could affect, among other things, inflation and the securities markets generally. Other unexpected political, regulatory and diplomatic events within the U.S. and abroad may affect investor and consumer confidence and may adversely impact financial markets and the broader economy. For example, ongoing armed conflicts between Russia and Ukraine in Europe and among Israel, Iran, Hamas and other militant groups in the Middle East, have caused and could continue to cause significant market disruptions and volatility within the markets in Russia, Europe, the Middle East and the United States. The hostilities and sanctions resulting from those hostilities have and could continue to have a significant impact on certain Fund investments as well as Fund performance and liquidity. The economies of the United States and its trading partners, as well as the financial markets generally, may be adversely impacted by trade disputes&lt;/span&gt;&lt;span style="font-family:Arial;font-size:9.00pt;"&gt;,  &lt;/span&gt;&lt;span style="font-family:Arial;font-size:9.00pt;margin-left:0%;"&gt;including the imposition of tariffs,&lt;/span&gt;&lt;span style="font-family:Arial;font-size:9.00pt;"&gt; and other matters. For example, the United States has imposed trade barriers and restrictions &lt;/span&gt;&lt;span style="font-family:Arial;font-size:9.00pt;margin-left:0%;"&gt;on China. In addition, the Chinese government is engaged in a longstanding dispute with Taiwan, continually threatening an &lt;/span&gt;&lt;span style="color:#000000;font-family:Arial;font-size:9.00pt;margin-left:0%;"&gt;invasion. If the political climate between the United States and China does not improve or continues to deteriorate, if China were to attempt invading Taiwan, or if other geopolitical conflicts develop or worsen, economies, markets and individual securities may be adversely affected, and the value of the Fund&#x2019;s assets may go down. A public health crisis and the ensuing policies enacted by governments and central banks may cause significant volatility and uncertainty in global financial markets, negatively impacting global growth prospects. As the COVID-19 global pandemic illustrated, such events may affect certain geographic regions, countries, sectors and industries more significantly than others. Advancements in technology may also adversely impact markets and the overall performance of the Fund. For instance, the economy may be significantly impacted by the advanced development and increased regulation of artificial intelligence. Additionally, cyber security breaches of both government and non-government entities could have negative impacts on infrastructure and the ability of such entities, including the Fund, to operate properly. These events, and any other future events, may adversely affect the prices and liquidity &lt;/span&gt;&lt;span style="color:#000000;font-family:Arial;font-size:9.00pt;"&gt;of the Fund&#x2019;s portfolio investments and could result in disruptions in the trading markets.&lt;/span&gt;</oef:RiskTextBlock>

In addition, &lt;/span&gt;&lt;span style="font-family:Arial;font-size:9.00pt;margin-left:0%;"&gt;cyber security breaches of the issuers of securities in which the Fund invests or the Fund&#x2019;s third-party service providers, such as its administrator, transfer agent, custodian, or sub-advisor, as applicable, &lt;/span&gt;&lt;span style="font-family:Arial;font-size:9.00pt;"&gt;among many other third-party service providers,  &lt;/span&gt;&lt;span style="font-family:Arial;font-size:9.00pt;margin-left:0%;"&gt;can also subject the Fund to many of the same risks associated with direct cyber security breaches. &lt;/span&gt;&lt;span style="font-family:Arial;font-size:9.00pt;"&gt;Further, errors, misconduct, &lt;/span&gt;&lt;span style="font-family:Arial;font-size:9.00pt;margin-left:0%;"&gt;or compromise of accounts of employees of the Fund or its third-party service providers can also create material cybersecurity risks.&lt;/span&gt;&lt;span style="font-family:Arial;font-size:9.00pt;"&gt; Although the Fund has established risk management systems designed to reduce the risks associated with cyber security, &lt;/span&gt;&lt;span style="font-family:Arial;font-size:9.00pt;margin-left:0%;"&gt;there is no guarantee that such efforts will succeed, especially because the Fund does not directly control the cyber security systems of issuers or third-party service providers.&lt;/span&gt;&lt;span style="font-family:Arial;font-size:9.00pt;"&gt; Cyber security incidents may also trigger Fund obligations under data privacy &lt;/span&gt;&lt;span style="font-family:Arial;font-size:9.00pt;margin-left:0%;"&gt;laws, potentially increasing notification and compliance burdens.

Credit risk refers to &lt;/span&gt;&lt;span style="font-family:Arial;font-size:9.00pt;margin-left:0%;"&gt;the possibility that the issuer or other obligor of a security will not be able or willing to make payments of interest and principal when due. Generally, the value of debt securities will change inversely with changes in interest rates. To the extent that interest rates rise, certain underlying obligations may be paid off substantially slower than originally anticipated and the value of those securities may fall sharply. During periods of falling interest rates, the income received by the Fund may decline. If the principal on a debt security is prepaid before expected, the prepayments of principal may have to be reinvested in obligations paying interest at lower rates. Debt securities generally do not trade on a securities exchange making them generally less liquid and more difficult to value than common stock.&lt;/span&gt;&lt;span style="font-family:Arial;font-size:9.00pt;"&gt; Debt securities held by the Fund may be subject to amendments, waivers, or &lt;/span&gt;&lt;span style="font-family:Arial;font-size:9.00pt;margin-left:0%;"&gt;exchange offers that modify their terms. These transactions may be initiated by borrowers to address financial stress and may include exchanges of existing debt securities for new instruments with different priority, collateral, or economic characteristics. Participation in, or exclusion from, such transactions could result in the Fund holding debt that is structurally or contractually &lt;/span&gt;&lt;span style="font-family:Arial;font-size:9.00pt;"&gt;subordinated, less liquid, or of lower market value than prior to the transaction.&lt;/span&gt;</oef:RiskTextBlock>

Investments in emerging markets securities are generally considered speculative in nature and are subject to the following heightened risks: smaller market capitalization of securities markets which may suffer periods of relative illiquidity; significant &lt;/span&gt;&lt;span style="color:#000000;font-family:Arial;font-size:9.00pt;margin-left:0%;"&gt;price volatility; restrictions on foreign investment; possible repatriation of investment income and capital; rapid inflation; and currency convertibility issues. Emerging market countries also often have less uniformity in accounting, auditing and reporting requirements, unsettled securities laws, unreliable securities valuation and greater risk associated with custody of securities. Financial and other reporting by companies and government entities also may be less reliable in emerging market countries. Shareholder claims that are available in the U.S., as well as regulatory oversight and authority that is common in the U.S., including for claims based on fraud, may be difficult or impossible for shareholders of securities in emerging market countries or for U.S. authorities to pursue. Furthermore, investors may be required to register the proceeds of sales and future economic or political crises could lead to price controls, forced mergers, expropriation or confiscatory taxation, seizure, nationalization &lt;/span&gt;&lt;span style="color:#000000;font-family:Arial;font-size:9.00pt;"&gt;or creation of government monopolies.&lt;/span&gt;</oef:RiskTextBlock>

In these member states, the authority to direct monetary policies, including money supply and official interest rates for the Euro, is exercised by the European Central Bank. In a 2016 referendum, the United Kingdom elected to withdraw from the EU (&lt;/span&gt;&lt;span style="color:#000000;font-family:Arial;font-size:9.00pt;font-style:italic;"&gt;&#x201c;Brexit&#x201d;&lt;/span&gt;&lt;span style="color:#000000;font-family:Arial;font-size:9.00pt;"&gt;).

As the second largest economy among EU members, the implications of the United Kingdom&#x2019;s withdrawal are difficult to gauge and cannot be fully known. Its departure may negatively impact the EU and Europe as a whole by causing volatility within the EU, triggering prolonged economic downturns in certain European countries or sparking additional member states to contemplate departing the EU (thereby perpetuating &lt;/span&gt;&lt;span style="color:#000000;font-family:Arial;font-size:9.00pt;"&gt;political instability in the region).&lt;/span&gt;</oef:RiskTextBlock>

As a result, the coupon on floating rate securities will generally decline in a falling interest rate environment, causing the Fund to experience a reduction in the income it receives from the security. A floating rate security&#x2019;s coupon rate resets periodically according to the terms of the security. Consequently, in a rising interest rate environment, floating rate securities with coupon rates that reset infrequently may lag behind the changes in market interest rates. Floating rate securities may also contain terms that impose a maximum coupon rate the issuer will pay, regardless of &lt;/span&gt;&lt;span style="color:#000000;font-family:Arial;font-size:9.00pt;"&gt;the level of the reference rate which would decrease the value of the security.&lt;/span&gt;</oef:RiskTextBlock>

Interest rate risk is generally lower for shorter term debt securities and higher for longer-term debt securities. The Fund may be subject to a greater risk of rising interest rates than would normally be the case during periods of low interest rates. Duration is a reasonably accurate measure of a debt security&#x2019;s price sensitivity to changes in interest rates and a common measure of interest rate risk. Duration measures a debt security&#x2019;s expected life on a present value basis, taking into account the debt security&#x2019;s yield, interest payments and final maturity. In general, duration represents the expected percentage change in the value of a security for an immediate 1% change in interest rates. For example, the price of a debt security with a three-year duration would be expected to drop by approximately 3% in response to a 1% increase in interest rates. Therefore, prices of debt securities with shorter durations tend to be less sensitive to interest rate changes than debt securities with longer durations. Higher sensitivity to interest rates is generally correlated with higher levels of &lt;/span&gt;&lt;span style="color:#000000;font-family:Arial;font-size:9.00pt;"&gt;volatility and, therefore, greater risk. As the value of a debt security changes over time, so will its duration.&lt;/span&gt;</oef:RiskTextBlock>

Generally, holders of preferred securities have no voting rights with respect to the issuing company unless preferred dividends have been in arrears for a specified number of periods, at which time the preferred security holders may obtain limited rights. In certain circumstances, an issuer of preferred securities may defer payment on the securities and, in some cases, redeem the securities prior to a &lt;/span&gt;&lt;span style="color:#000000;font-family:Arial;font-size:9.00pt;"&gt;specified date.

The Fund&#x2019;s investment advisor cannot predict whether shares will trade below, at or above their net asset value because the shares trade on the Exchange at market prices and not at net asset value. Price differences may be due, in large part, to the fact that supply and demand forces at work in the secondary trading market for shares will be closely related, but not identical, to the same forces influencing the prices of the holdings of the Fund trading individually or in the aggregate at any point in time. However, given that shares can only be purchased and redeemed in Creation Units, and only to and from broker-dealers and large institutional investors that have entered into participation agreements (unlike shares of closed-end funds, which frequently trade at appreciable &lt;/span&gt;&lt;span style="color:#000000;font-family:Arial;font-size:9.00pt;margin-left:0%;"&gt;discounts from, and sometimes at premiums to, their net asset value), the Fund&#x2019;s investment advisor believes that large discounts or premiums to the net asset value of shares should not be sustained. During stressed market conditions, the market for the Fund&#x2019;s shares may become less liquid in response to deteriorating liquidity in the market for the Fund&#x2019;s underlying portfolio holdings, which could in turn lead to differences between the market price of the Fund&#x2019;s shares and their net asset &lt;/span&gt;&lt;span style="color:#000000;font-family:Arial;font-size:9.00pt;"&gt;value and the bid/ask spread on the Fund&#x2019;s shares may widen.&lt;/span&gt;</oef:RiskTextBlock>

As a result, investments in REITs are subject to the risks associated with investing in real estate, which may include, but are not limited to: fluctuations in the value of underlying properties; defaults by borrowers or tenants; market saturation; changes in general and local operating expenses; and other economic, political or regulatory occurrences affecting companies in the real estate sector. REITs are also subject to the risk that the real estate market may experience an economic downturn generally, which may have a material effect on the real estate in which the REITs invest and their underlying portfolio securities. REITs may have also a relatively small market capitalization which may result in their shares experiencing less market liquidity and greater price volatility than larger companies. Increases in interest rates typically lower the present value of a REIT's future earnings stream, and may make financing property purchases and improvements more costly. Because the market price of REIT stocks may change based upon investors' collective perceptions of future &lt;/span&gt;&lt;span style="color:#000000;font-family:Arial;font-size:9.00pt;"&gt;earnings, the value of the Fund will generally decline when investors anticipate or experience rising interest rates.&lt;/span&gt;</oef:RiskTextBlock>

This may occur because the asset or security does not trade on a centralized exchange, or in times of market turmoil or reduced liquidity. There are multiple methods that can be used to value a portfolio holding when market quotations are not readily available. The value established for any portfolio holding at a point in time might differ from what would be produced using a different methodology or if it had been priced using market quotations. Portfolio holdings that are valued using techniques other than market quotations, including &#x201c;fair valued&#x201d; assets or securities, may be subject to greater fluctuation in their valuations from one day to the next than if market quotations were used. In addition, there is no assurance that the Fund could sell or close out a portfolio position for the value established for it at any time, and it is possible that the Fund would incur a loss because a portfolio position is sold or closed out at a discount to the valuation established by the Fund at that time.

The Fund pursues its investment objective by establishing long and short positions in its portfolio of U.S. exchange-listed equity securities and ETFs. The Fund&#x2019;s portfolio may include U.S. exchange-listed equity securities of non-U.S. &lt;/span&gt;&lt;span style="color:#000000;font-family:Arial;font-size:9.00pt;"&gt;issuers, including the securities of non-U.S. issuers traded on U.S. exchanges in the form of depositary receipts.  &lt;/span&gt;&lt;span style="color:#000000;font-family:Arial;font-size:9.00pt;margin-left:0%;"&gt;The Fund&#x2019;s portfolio is composed of both long and short positions in equity securities and ETFs. As opposed to taking long positions in which an investor seeks to profit from increases in the price of a security, short selling is a technique that will be used by the Fund to try and profit from the falling price of a security. Short selling involves selling a security that has been &lt;/span&gt;&lt;span style="color:#000000;font-family:Arial;font-size:9.00pt;margin-left:0%;"&gt;borrowed from a third party with the intention of buying an identical security back at a later date to return to that third party. Having both long and short positions in an equity security portfolio is a common way to create returns that are independent of market moves. One advantage of a long and short portfolio is that the long and short positions may offset one another in a manner that results in a lower net exposure to the direction of the market. In addition, cash balances arising from the use &lt;/span&gt;&lt;span style="color:#000000;font-family:Arial;font-size:9.00pt;"&gt;of short selling typically will be held in money market instruments.  &lt;/span&gt;&lt;span style="color:#000000;font-family:Arial;font-size:9.00pt;margin-left:0%;"&gt;The Fund&#x2019;s investment advisor will manage the Fund&#x2019;s portfolio using an investment process that analyzes fundamental, market-related, technical and statistical attributes of eligible securities to assess total return potential. The Fund&#x2019;s investment advisor will then use this analysis as the basis to establish long and short positions within the Fund&#x2019;s portfolio. The Fund pursues its objective by using a variety of quantitative tools to select securities that the Fund&#x2019;s investment advisor believes will either outperform (the &lt;/span&gt;&lt;span style="color:#000000;font-family:Arial;font-size:9.00pt;font-style:italic;"&gt;&#x201c;long basket&#x201d;&lt;/span&gt;&lt;span style="color:#000000;font-family:Arial;font-size:9.00pt;"&gt;) or underperform (the &lt;/span&gt;&lt;span style="color:#000000;font-family:Arial;font-size:9.00pt;font-style:italic;"&gt;&#x201c;short basket&#x201d;&lt;/span&gt;&lt;span style="color:#000000;font-family:Arial;font-size:9.00pt;"&gt;). Preliminary rankings of the positions will rely on the &lt;/span&gt;&lt;span style="color:#000000;font-family:Arial;font-size:9.00pt;margin-left:0%;"&gt;Sabrient Systems Earnings Quality Rank (EQR) model and the proprietary research of the Fund&#x2019;s investment advisor. Long and short baskets are then integrated and optimized to build a final portfolio. The overall portfolio, under normal market conditions, will be 80 to 100% invested in long positions and 0% to 50% invested in short positions. The Fund will not use proceeds from the short positions to add leverage to the long positions, and as such, the Fund will not have a net long exposure of greater than 100% and may hold a large cash position. The Fund&#x2019;s investment advisor may alter the size of the short positions and/or the risk profile of the short positions based upon its assessment of the equity markets. Additionally, the notional position &lt;/span&gt;&lt;span style="color:#000000;font-family:Arial;font-size:9.00pt;"&gt;of the short positions may be reduced significantly or eliminated temporarily.  &lt;/span&gt;&lt;span style="color:#000000;font-family:Arial;font-size:9.00pt;margin-left:0%;"&gt;The Fund may invest up to 20% of its net assets (including investment borrowings) in U.S. exchange-listed equity index futures &lt;/span&gt;&lt;span style="color:#000000;font-family:Arial;font-size:9.00pt;"&gt;contracts. These futures contracts will be used to gain long or short exposure to broad based equity indexes.  &lt;/span&gt;&lt;span style="font-family:Arial;font-size:9.00pt;margin-left:0%;"&gt;The Fund and the ETFs held by the Fund may invest in equity securities of master limited partnerships (&lt;/span&gt;&lt;span style="font-family:Arial;font-size:9.00pt;font-style:italic;"&gt;"MLPs"&lt;/span&gt;&lt;span style="font-family:Arial;font-size:9.00pt;"&gt;) and real estate &lt;/span&gt;&lt;span style="font-family:Arial;font-size:9.00pt;margin-left:0%;"&gt;investment trusts (&lt;/span&gt;&lt;span style="font-family:Arial;font-size:9.00pt;font-style:italic;"&gt;"REITs"&lt;/span&gt;&lt;span style="font-family:Arial;font-size:9.00pt;"&gt;). &lt;/span&gt;&lt;span style="font-family:Arial;font-size:9.00pt;"&gt;As of January 30, 2026 the Fund had significant investments in information technology companies, &lt;/span&gt;&lt;span style="font-family:Arial;font-size:9.00pt;margin-left:0%;"&gt;although this may change from time to time.&lt;/span&gt;&lt;span style="font-family:Arial;font-size:9.00pt;"&gt;Over time, the Fund may have significant investments in a jurisdiction, investment &lt;/span&gt;&lt;span style="font-family:Arial;font-size:9.00pt;margin-left:0%;"&gt;sector or industry or group of industries that it may not have had as of January&lt;/span&gt;&lt;span style="font-family:Arial;font-size:9.00pt;"&gt; 30, 2026.

As a means to fight inflation, &lt;/span&gt;&lt;span style="font-family:Arial;font-size:9.00pt;"&gt;the Federal Reserve and &lt;/span&gt;&lt;span style="font-family:Arial;font-size:9.00pt;margin-left:0%;"&gt;certain foreign central banks have raised interest rates; however, the Federal Reserve has &lt;/span&gt;&lt;span style="font-family:Arial;font-size:9.00pt;"&gt;begun to lower interest rates and &lt;/span&gt;&lt;span style="font-family:Arial;font-size:9.00pt;margin-left:0%;"&gt;may continue to do so. U.S. regulators have proposed several changes to market and issuer regulations which would directly impact the Fund, and any regulatory changes could adversely impact the Fund&#x2019;s ability to achieve its investment strategies or make certain investments. &lt;/span&gt;&lt;span style="font-family:Arial;font-size:9.00pt;"&gt;Potential future bank failures could result in disruption to the broader banking industry or markets &lt;/span&gt;&lt;span style="font-family:Arial;font-size:9.00pt;margin-left:0%;"&gt;generally and reduce confidence in financial institutions and the economy as a whole, which may also heighten market volatility &lt;/span&gt;&lt;span style="font-family:Arial;font-size:9.00pt;margin-left:0%;"&gt;and reduce liquidity. Additionally, challenges in commercial real estate markets, including &lt;/span&gt;&lt;span style="font-family:Arial;font-size:9.00pt;"&gt;high interest rates, declining valuations &lt;/span&gt;&lt;span style="font-family:Arial;font-size:9.00pt;margin-left:0%;"&gt;and &lt;/span&gt;&lt;span style="font-family:Arial;font-size:9.00pt;"&gt;elevated vacancies, could have a broader impact on financial markets. The ongoing adversarial political climate in the &lt;/span&gt;&lt;span style="font-family:Arial;font-size:9.00pt;margin-left:0%;"&gt;United States, as well as political and diplomatic events both domestic and abroad, have and may continue to have an adverse impact the U.S. regulatory landscape, markets and investor behavior, which could have a negative impact on the Fund&#x2019;s investments and operations. The change in administration resulting from the 2024 United States national elections could result in significant impacts to international trade relations, tax and immigration policies, and other aspects of the national and international political and financial landscape, which could affect, among other things, inflation and the securities markets generally. Other unexpected political, regulatory and diplomatic events within the U.S. and abroad may affect investor and consumer confidence and may adversely impact financial markets and the broader economy. For example, ongoing armed conflicts between Russia and Ukraine in Europe and among Israel, Iran, Hamas and other militant groups in the Middle East, have caused and could continue to cause significant market disruptions and volatility within the markets in Russia, Europe, the Middle East and the United States. The hostilities and sanctions resulting from those hostilities have and could continue to have a significant impact on certain Fund investments as well as Fund performance and liquidity. The economies of the United States and its trading partners, as well as the financial markets generally, may be adversely impacted by trade disputes&lt;/span&gt;&lt;span style="font-family:Arial;font-size:9.00pt;"&gt;,  &lt;/span&gt;&lt;span style="font-family:Arial;font-size:9.00pt;margin-left:0%;"&gt;including the imposition of tariffs,&lt;/span&gt;&lt;span style="font-family:Arial;font-size:9.00pt;"&gt; and other matters. For example, the United States has imposed trade barriers and restrictions &lt;/span&gt;&lt;span style="font-family:Arial;font-size:9.00pt;margin-left:0%;"&gt;on China. In addition, the Chinese government is engaged in a longstanding dispute with Taiwan, continually threatening an invasion. If the political climate between the United States and China does not improve or continues to deteriorate, if China were to attempt invading Taiwan, or if other geopolitical conflicts develop or worsen, economies, markets and individual securities may be adversely affected, and the value of the Fund&#x2019;s assets may go down. A public health crisis and the ensuing policies enacted by governments and central banks may cause significant volatility and uncertainty in global financial markets, negatively impacting global growth prospects. As the COVID-19 global pandemic illustrated, such events may affect certain geographic regions, countries, sectors and industries more significantly than others. Advancements in technology may also adversely impact markets and the overall performance of the Fund. For instance, the economy may be significantly impacted by the advanced development and increased regulation of artificial intelligence. Additionally, cyber security breaches of both government and non-government entities could have negative impacts on infrastructure and the ability of such entities, including the Fund, to operate properly. These events, and any other future events, may adversely affect the prices and liquidity &lt;/span&gt;&lt;span style="font-family:Arial;font-size:9.00pt;"&gt;of the Fund&#x2019;s portfolio investments and could result in disruptions in the trading markets.&lt;/span&gt;</oef:RiskTextBlock>

A breach in cyber security refers to both intentional and unintentional events that may cause the Fund to lose proprietary information, suffer data corruption or lose operational capacity&lt;/span&gt;&lt;span style="font-family:Arial;font-size:9.00pt;"&gt;, any of which could result in a material adverse &lt;/span&gt;&lt;span style="font-family:Arial;font-size:9.00pt;margin-left:0%;"&gt;effect on the Fund or its shareholders&lt;/span&gt;&lt;span style="font-family:Arial;font-size:9.00pt;"&gt;.

These risks include or may include: (i) the risk that the &lt;/span&gt;&lt;span style="color:#000000;font-family:Arial;font-size:9.00pt;margin-left:0%;"&gt;value of the underlying assets may go up or down; (ii) the risk that the counterparty to a derivative transaction may not fulfill its contractual obligations; (iii) the risk of mispricing or improper valuation of a derivative; (iv) the risk that changes in the value of the derivative may not correlate perfectly with the underlying asset; (v) the risk that a derivative instrument cannot be sold, closed out or replaced quickly at or very close to its fundamental value; (vi) the risk of loss caused by the unenforceability of a party&#x2019;s obligations under the derivative; and (vii) the risk that a disruption in the financial markets will cause difficulties for all market participants. Derivative prices are highly volatile and may fluctuate substantially during a short period of time. Such prices are influenced by numerous factors that affect the markets, including, but not limited to: changing supply and demand relationships; government programs and policies; national and international political and economic events, changes in interest rates, inflation and deflation and changes in supply and demand relationships. Trading derivative instruments involves risks different from, or possibly greater than, the risks associated with investing directly in securities. Derivative contracts ordinarily have leverage inherent in their terms. The low margin deposits normally required in trading derivatives, including futures contracts, permit a high degree of leverage. Accordingly, a relatively small price movement may result in an immediate and substantial loss. The use of leverage may also cause the Fund to liquidate portfolio positions when it would not be advantageous to do so. The use of leveraged derivatives can magnify potential for gain or loss and, therefore, amplify the &lt;/span&gt;&lt;span style="color:#000000;font-family:Arial;font-size:9.00pt;"&gt;effects of market volatility on share price.&lt;/span&gt;</oef:RiskTextBlock>

Equity securities prices fluctuate for several reasons, including changes in investors&#x2019; perceptions of the financial condition of an issuer or the general condition of the relevant equity market, such as market volatility, or when political or economic events affecting an issuer occur. Common stock prices may be particularly sensitive to rising interest rates, as the cost of capital rises and borrowing costs increase. Equity securities may decline significantly in price over short or extended periods of time, and such declines may occur in the equity market as a whole, or they may occur in only a particular country, &lt;/span&gt;&lt;span style="font-family:Arial;font-size:9.00pt;"&gt;company, industry or sector of the market.&lt;/span&gt;</oef:RiskTextBlock>

The risk of a position in a futures contract may be very large compared to the relatively low level of margin the Fund is required to deposit. In many cases, a relatively small price movement in a futures contract may result in immediate and substantial loss or gain to the investor relative to the size of a required margin deposit. In the event no secondary market exists for a particular contract, it might not be possible to effect closing transactions, and the Fund will be unable to terminate the derivative. If the Fund uses futures contracts for hedging purposes, there is a risk of imperfect correlation between movements in the prices of the derivatives and movements in the securities or index underlying the derivatives or movements in the prices of the Fund's investments that are the subject of such hedge. The prices of futures contracts may not correlate perfectly with movements &lt;/span&gt;&lt;span style="color:#000000;font-family:Arial;font-size:9.00pt;"&gt;in the securities or index underlying them.&lt;/span&gt;</oef:RiskTextBlock>

Inclusion in an index could increase demand for the Fund and removal from an index could result in outsized selling activity in a relatively short period of time.

MLP common units can be affected by macro-economic factors and other factors unique to the partnership or company and the industry or industries in which the MLP operates. Certain MLP securities may trade in relatively low volumes due to their smaller capitalizations or other factors, which may cause them to have a high degree of price volatility and illiquidity. The structures of MLPs create certain risks, including, for example, risks related to the limited ability of investors to control an MLP and to vote on matters affecting the MLP, risks related to potential conflicts of interest between an MLP and the MLP's general partner, the risk that an MLP will generate insufficient cash flow to meet its current operating requirements, the risk that an MLP will issue additional securities or engage in other transactions that will have the effect of diluting the interests of existing investors, and risks related to the general partner's right to require unit-holders to sell their common units at an undesirable time or price.

The Fund&#x2019;s investment advisor cannot predict whether shares will trade below, at or above their net asset value because the shares trade on the Exchange at market prices and not at net asset value. Price differences may be due, in large part, to the fact that supply and demand forces at work in the secondary trading market for shares will be closely related, but not identical, to the same forces influencing the prices of the holdings of the Fund trading individually or in the aggregate at any point in time. However, given that shares can only be purchased and redeemed in Creation Units, and only to and from broker-dealers and large institutional investors that have entered into participation agreements (unlike shares of closed-end funds, which frequently trade at appreciable discounts from, and sometimes at premiums to, their net asset value), the Fund&#x2019;s investment advisor believes that large discounts or premiums to the net asset value of shares should not be sustained. During stressed market conditions, the market for the Fund&#x2019;s shares may become less liquid in response to deteriorating liquidity in the market for the Fund&#x2019;s underlying portfolio holdings, which could in turn lead to differences between the market price of the Fund&#x2019;s shares and their net asset &lt;/span&gt;&lt;span style="color:#000000;font-family:Arial;font-size:9.00pt;"&gt;value and the bid/ask spread on the Fund&#x2019;s shares may widen.&lt;/span&gt;</oef:RiskTextBlock>

As a result, investments in REITs are subject to the risks associated with investing in real estate, which may include, but are not limited to: fluctuations in the value of underlying properties; defaults by borrowers or tenants; market saturation; changes in general and local operating expenses; and other economic, political or regulatory occurrences affecting companies in the real estate sector. REITs are also subject to the risk that the real estate market may experience an economic downturn generally, which may have a material effect on the real estate in which the REITs invest and their underlying portfolio securities. REITs may have also a relatively small market capitalization which may result in their shares experiencing less market liquidity and greater price volatility than larger companies. Increases in interest rates typically lower the present value of a REIT's future earnings stream, and may make financing property purchases and improvements more costly. Because the market price of REIT stocks may change based upon investors' collective perceptions of future &lt;/span&gt;&lt;span style="color:#000000;font-family:Arial;font-size:9.00pt;"&gt;earnings, the value of the Fund will generally decline when investors anticipate or experience rising interest rates.&lt;/span&gt;</oef:RiskTextBlock>

This may occur because the asset or security does not trade on a centralized exchange, or in times of market turmoil or reduced liquidity. There are multiple methods that can be used to value a portfolio holding when market quotations are not readily available. The value established for any portfolio holding at a point in time might differ from what would be produced using a different methodology or if it had been priced using market quotations. Portfolio holdings that are valued using techniques other than market quotations, including &#x201c;fair valued&#x201d; assets or securities, may be subject to greater fluctuation in their valuations from one day to the next than if market quotations were used. In addition, there is no assurance that the Fund could sell or close out a portfolio position for the value established for it at any time, and it is possible that the Fund would incur a loss because a portfolio position is sold or closed out at a discount to the valuation established by the Fund at that time.

The Fund may invest up to 35% of its net assets in securities that are, at the time of investment, rated below investment grade (or securities that are unrated and determined by the Fund&#x2019;s investment advisor to be of comparable quality), commonly referred to as &lt;/span&gt;&lt;span style="font-family:Arial;font-size:9.00pt;font-style:italic;"&gt;&#x201c;high yield&#x201d;&lt;/span&gt;&lt;span style="font-family:Arial;font-size:9.00pt;"&gt; or &lt;/span&gt;&lt;span style="font-family:Arial;font-size:9.00pt;font-style:italic;"&gt;&#x201c;junk&#x201d;&lt;/span&gt;&lt;span style="font-family:Arial;font-size:9.00pt;"&gt; bonds.

As a means to fight inflation, &lt;/span&gt;&lt;span style="font-family:Arial;font-size:9.00pt;"&gt;the Federal Reserve and &lt;/span&gt;&lt;span style="font-family:Arial;font-size:9.00pt;margin-left:0%;"&gt;certain foreign central banks have raised interest rates; however, the Federal Reserve has &lt;/span&gt;&lt;span style="font-family:Arial;font-size:9.00pt;"&gt;begun to lower interest rates and &lt;/span&gt;&lt;span style="font-family:Arial;font-size:9.00pt;margin-left:0%;"&gt;may continue to do so. U.S. regulators have proposed several changes to market and issuer regulations which would directly impact the Fund, and any regulatory changes could adversely impact the Fund&#x2019;s ability to achieve its investment strategies or make certain investments. &lt;/span&gt;&lt;span style="font-family:Arial;font-size:9.00pt;"&gt;Potential future bank failures could result in disruption to the broader banking industry or markets &lt;/span&gt;&lt;span style="font-family:Arial;font-size:9.00pt;margin-left:0%;"&gt;generally and reduce confidence in financial institutions and the economy as a whole, which may also heighten market volatility and reduce liquidity. Additionally, challenges in commercial real estate markets, including &lt;/span&gt;&lt;span style="font-family:Arial;font-size:9.00pt;"&gt;high interest rates, declining valuations &lt;/span&gt;&lt;span style="font-family:Arial;font-size:9.00pt;margin-left:0%;"&gt;and &lt;/span&gt;&lt;span style="font-family:Arial;font-size:9.00pt;"&gt;elevated vacancies, could have a broader impact on financial markets. The ongoing adversarial political climate in the &lt;/span&gt;&lt;span style="font-family:Arial;font-size:9.00pt;margin-left:0%;"&gt;United States, as well as political and diplomatic events both domestic and abroad, have and may continue to have an adverse impact the U.S. regulatory landscape, markets and investor behavior, which could have a negative impact on the Fund&#x2019;s investments and operations. The change in administration resulting from the 2024 United States national elections could result in significant impacts to international trade relations, tax and immigration policies, and other aspects of the national and international political and financial landscape, which could affect, among other things, inflation and the securities markets generally. Other unexpected political, regulatory and diplomatic events within the U.S. and abroad may affect investor and consumer confidence and may adversely impact financial markets and the broader economy. For example, ongoing armed conflicts between Russia and Ukraine in Europe and among Israel, Iran, Hamas and other militant groups in the Middle East, have caused and could continue to cause significant market disruptions and volatility within the markets in Russia, Europe, the Middle East and the United States. The hostilities and sanctions resulting from those hostilities have and could continue to have a significant impact on certain Fund investments as well as Fund performance and liquidity. The economies of the United States and its trading partners, as well as the financial markets generally, may be adversely impacted by trade disputes&lt;/span&gt;&lt;span style="font-family:Arial;font-size:9.00pt;"&gt;,  &lt;/span&gt;&lt;span style="font-family:Arial;font-size:9.00pt;margin-left:0%;"&gt;including the imposition of tariffs,&lt;/span&gt;&lt;span style="font-family:Arial;font-size:9.00pt;"&gt; and other matters. For example, the United States has imposed trade barriers and restrictions &lt;/span&gt;&lt;span style="font-family:Arial;font-size:9.00pt;margin-left:0%;"&gt;on China. In addition, the Chinese government is engaged in a longstanding dispute with Taiwan, continually threatening an invasion. If the political climate between the United States and China does not improve or continues to deteriorate, if China were to attempt invading Taiwan, or if other geopolitical conflicts develop or worsen, economies, markets and individual securities may be adversely affected, and the value of the Fund&#x2019;s assets may go down. A public health crisis and the ensuing policies enacted by governments and central banks may cause significant volatility and uncertainty in global financial markets, negatively impacting global growth prospects. As the COVID-19 global pandemic illustrated, such events may affect certain geographic regions, countries, sectors and industries more significantly than others. Advancements in technology may also adversely impact markets and the overall performance of the Fund. For instance, the economy may be significantly impacted by the advanced development and increased regulation of artificial intelligence. Additionally, cyber security breaches of both government and non-government entities could have negative impacts on infrastructure and the ability of such entities, &lt;/span&gt;&lt;span style="color:#000000;font-family:Arial;font-size:9.00pt;margin-left:0%;"&gt;including the Fund, to operate properly. These events, and any other future events, may adversely affect the prices and liquidity &lt;/span&gt;&lt;span style="color:#000000;font-family:Arial;font-size:9.00pt;"&gt;of the Fund&#x2019;s portfolio investments and could result in disruptions in the trading markets.&lt;/span&gt;</oef:RiskTextBlock>

A breach in cyber security refers to both intentional and unintentional events that may cause the Fund to lose proprietary information, suffer data corruption or lose operational capacity&lt;/span&gt;&lt;span style="font-family:Arial;font-size:9.00pt;"&gt;, any of which could result in a material adverse &lt;/span&gt;&lt;span style="font-family:Arial;font-size:9.00pt;margin-left:0%;"&gt;effect on the Fund or its shareholders&lt;/span&gt;&lt;span style="font-family:Arial;font-size:9.00pt;"&gt;.

Cyber security breaches may involve unauthorized access to the Fund&#x2019;s digital information systems through &#x201c;hacking&#x201d; or malicious software coding but may also result from outside attacks such as denial-of-service attacks through efforts to make network services unavailable to intended users. &lt;/span&gt;&lt;span style="font-family:Arial;font-size:9.00pt;"&gt;Emerging threats like ransomware or zero-day exploits could also cause disruptions to Fund operations. In addition, &lt;/span&gt;&lt;span style="font-family:Arial;font-size:9.00pt;margin-left:0%;"&gt;cyber security breaches of the issuers of securities in which the Fund invests or the Fund&#x2019;s third-party service providers, such as its administrator, transfer agent, custodian, or sub-advisor, as applicable, &lt;/span&gt;&lt;span style="font-family:Arial;font-size:9.00pt;"&gt;among many other third-party service providers,  &lt;/span&gt;&lt;span style="font-family:Arial;font-size:9.00pt;margin-left:0%;"&gt;can also subject the Fund to many of the same risks associated with direct cyber security breaches. &lt;/span&gt;&lt;span style="font-family:Arial;font-size:9.00pt;"&gt;Further, errors, misconduct, &lt;/span&gt;&lt;span style="font-family:Arial;font-size:9.00pt;margin-left:0%;"&gt;or compromise of accounts of employees of the Fund or its third-party service providers can also create material cybersecurity risks.&lt;/span&gt;&lt;span style="font-family:Arial;font-size:9.00pt;"&gt; Although the Fund has established risk management systems designed to reduce the risks associated with cyber security, &lt;/span&gt;&lt;span style="font-family:Arial;font-size:9.00pt;margin-left:0%;"&gt;there is no guarantee that such efforts will succeed, especially because the Fund does not directly control the cyber security systems of issuers or third-party service providers.&lt;/span&gt;&lt;span style="font-family:Arial;font-size:9.00pt;"&gt; Cyber security incidents may also trigger Fund obligations under data privacy &lt;/span&gt;&lt;span style="font-family:Arial;font-size:9.00pt;margin-left:0%;"&gt;laws, potentially increasing notification and compliance burdens. Cyber security incidents affecting issuers in whose securities the Fund invests may also have a negative impact on the value of the securities of such issuers, and in turn, the value of the &lt;/span&gt;&lt;span style="font-family:Arial;font-size:9.00pt;"&gt;Fund.&lt;/span&gt;</oef:RiskTextBlock>

Credit risk refers to &lt;/span&gt;&lt;span style="font-family:Arial;font-size:9.00pt;margin-left:0%;"&gt;the possibility that the issuer or other obligor of a security will not be able or willing to make payments of interest and principal when due. Generally, the value of debt securities will change inversely with changes in interest rates. To the extent that interest rates rise, certain underlying obligations may be paid off substantially slower than originally anticipated and the value of those securities may fall sharply. During periods of falling interest rates, the income received by the Fund may decline. If the principal on a debt security is prepaid before expected, the prepayments of principal may have to be reinvested in obligations paying interest at lower rates. Debt securities generally do not trade on a securities exchange making them generally less liquid and more difficult to value than common stock.&lt;/span&gt;&lt;span style="font-family:Arial;font-size:9.00pt;"&gt; Debt securities held by the Fund may be subject to amendments, waivers, or &lt;/span&gt;&lt;span style="font-family:Arial;font-size:9.00pt;margin-left:0%;"&gt;exchange offers that modify their terms. These transactions may be initiated by borrowers to address financial stress and may include exchanges of existing debt securities for new instruments with different priority, collateral, or economic characteristics. Participation in, or exclusion from, such transactions could result in the Fund holding debt that is structurally or contractually &lt;/span&gt;&lt;span style="font-family:Arial;font-size:9.00pt;"&gt;subordinated, less liquid, or of lower market value than prior to the transaction.&lt;/span&gt;</oef:RiskTextBlock>

These risks include or may include: (i) the risk that the value of the underlying assets may go up or down; (ii) the risk that the counterparty to a derivative transaction may not fulfill its contractual obligations; (iii) the risk of mispricing or improper valuation of a derivative; (iv) the risk that changes in the value of the derivative may not correlate perfectly with the underlying asset; (v) the risk that a derivative instrument cannot be sold, closed out or replaced quickly at or very close to its fundamental value; (vi) the risk of loss caused by the unenforceability of a party&#x2019;s obligations under the derivative; and (vii) the risk that a disruption in the financial markets will cause difficulties for all market participants. Derivative prices are highly volatile and may fluctuate substantially during a short period of time. Such prices are influenced by numerous factors that affect the markets, including, but not limited to: changing supply and demand relationships; government programs and policies; national and international political and economic events, changes in interest rates, inflation and deflation and changes in supply and demand relationships. Trading derivative instruments involves risks different from, or possibly greater than, the risks associated with investing directly in securities. Derivative contracts ordinarily have leverage inherent in their terms. The low margin deposits normally required in trading derivatives, including futures contracts, permit a high degree of leverage. Accordingly, a relatively small price movement may result in an immediate and substantial loss. The use of leverage may also cause the Fund to liquidate portfolio positions when it would not be advantageous to do so. The use of leveraged derivatives can magnify potential for gain or loss and, therefore, amplify the &lt;/span&gt;&lt;span style="color:#000000;font-family:Arial;font-size:9.00pt;"&gt;effects of market volatility on share price.&lt;/span&gt;</oef:RiskTextBlock>

Rising interest rates tend to extend the duration of debt securities, making their market value more sensitive to changes in interest rates. The &lt;/span&gt;&lt;span style="color:#000000;font-family:Arial;font-size:9.00pt;margin-left:0%;"&gt;value of longer-term debt securities generally changes more in response to changes in interest rates than shorter-term debt &lt;/span&gt;&lt;span style="color:#000000;font-family:Arial;font-size:9.00pt;"&gt;securities. As a result, in a period of rising interest rates, securities may exhibit additional volatility and may lose value.&lt;/span&gt;</oef:RiskTextBlock>

The risk of a position in a futures contract may be very large compared to the relatively low level of margin the Fund is required to deposit. In many cases, a relatively small price movement in a futures contract may result in immediate and substantial loss or gain to the investor relative to the size of a required margin deposit. In the event no secondary market exists for a particular contract, it might not be possible to effect closing transactions, and the Fund will be unable to terminate the derivative. If the Fund uses futures contracts for hedging purposes, there is a risk of imperfect correlation between movements in the prices of the derivatives and movements in the securities or index underlying the derivatives or movements in the prices of the Fund's investments that are the subject of such hedge. The prices of futures contracts may not correlate perfectly with movements &lt;/span&gt;&lt;span style="color:#000000;font-family:Arial;font-size:9.00pt;"&gt;in the securities or index underlying them.&lt;/span&gt;</oef:RiskTextBlock>

These bonds are normally secured only by the revenues from the project and are not general obligations of the issuer or otherwise secured by state or local government tax receipts.

Interest rate risk is generally lower for shorter term debt securities and higher for longer-term debt securities. The Fund may be subject to a greater risk of rising interest rates than would normally be the case during periods of low interest rates. Duration is a reasonably accurate measure of a debt security&#x2019;s price sensitivity to changes in interest rates and a common measure of interest rate risk. Duration measures a debt security&#x2019;s expected life on a present value basis, taking into account the debt security&#x2019;s yield, interest payments and final maturity. In general, duration represents the expected percentage change in the value of a security for an immediate 1% change in interest rates. For example, the price of a debt security with a three-year duration would be expected to drop by approximately 3% in response to a 1% increase in interest rates. Therefore, prices of debt securities with shorter durations tend to be less sensitive to interest rate changes than debt securities with longer durations. Higher sensitivity to interest rates is generally correlated with higher levels of &lt;/span&gt;&lt;span style="color:#000000;font-family:Arial;font-size:9.00pt;"&gt;volatility and, therefore, greater risk. As the value of a debt security changes over time, so will its duration.&lt;/span&gt;</oef:RiskTextBlock>

The values of municipal securities that depend on a specific revenue source to fund their payment obligations may fluctuate as a result of actual or anticipated changes in the cash flows generated by the revenue source or changes in the priority of the municipal obligation to receive the cash flows generated by the revenue source. The values of municipal securities held by the Fund may be adversely affected by local political and economic conditions and developments. Adverse conditions in an industry significant to a local economy could have a correspondingly adverse effect on the financial condition of local issuers. In addition, income from municipal securities held by the Fund could be declared taxable because of, among other things, unfavorable changes in tax laws, adverse interpretations by the Internal Revenue Service or state tax authorities, or noncompliant conduct of an issuer or other obligated party. Loss of tax-exempt status may cause interest received and distributed to shareholders by the Fund to be taxable and may result in a significant decline in the values of such municipal securities. Due to the COVID-19 pandemic, the risks of the municipal securities market have been magnified. The costs associated with combating the pandemic and the negative impact on tax revenues has adversely affected the financial condition of many states and political subdivisions. These risks may also adversely affect several sectors of the municipal bond market, such as airports, toll roads, hospitals and colleges, among many others.

The Fund&#x2019;s investment advisor cannot predict whether shares will trade below, at or above their net asset value because the shares trade on the Exchange at market prices and not at net asset value. Price differences may be due, in large part, to the fact that supply and demand forces at work in the secondary trading market for shares will be closely related, but not identical, to the same forces influencing the prices of the holdings of the Fund trading individually or in the aggregate at any point in time. However, given that shares can only be purchased and redeemed in Creation Units, and only to and from broker-dealers and large institutional investors that have entered into participation agreements (unlike shares of closed-end funds, which frequently trade at appreciable discounts from, and sometimes at premiums to, their net asset value), the Fund&#x2019;s investment advisor believes that large discounts or premiums to the net asset value of shares should not be sustained. During stressed market conditions, the market for the Fund&#x2019;s shares may become less liquid in response to deteriorating liquidity in the market for the Fund&#x2019;s underlying portfolio holdings, which could in turn lead to differences between the market price of the Fund&#x2019;s shares and their net asset &lt;/span&gt;&lt;span style="color:#000000;font-family:Arial;font-size:9.00pt;"&gt;value and the bid/ask spread on the Fund&#x2019;s shares may widen.&lt;/span&gt;</oef:RiskTextBlock>

Debt securities generally trade on an &#x201c;over-the-counter&#x201d; market. Due to the lack of centralized information and trading, and variations in lot sizes of certain debt securities, the valuation of debt securities may carry more uncertainty and risk than that of publicly traded securities. Debt securities are commonly valued by third-party pricing services that utilize a range of market-based inputs and assumptions, including readily available market quotations obtained from broker-dealers making markets in such securities, cash flows and transactions for comparable instruments. However, because the available information is less reliable and more subjective, elements of judgment may play a greater role in valuation of debt securities than for other types of securities. Different pricing services may incorporate different assumptions and inputs into their valuation methodologies, potentially resulting in different values for the same securities. As a result, if the Advisor were to change its valuation policies, or if the Fund were to change pricing services, or if a pricing service were to change its valuation methodology, there could be a material impact, either positive or negative, on the Fund&#x2019;s net asset value. Additionally, pricing services generally price debt securities assuming orderly transactions of an institutional &#x201c;round lot&#x201d; size, but some trades may occur in smaller, &#x201c;odd lot&#x201d; sizes, often at lower prices than institutional round lot trades. There is no assurance that the Fund will be able to sell a portfolio security at the price established by the pricing service, which could result in a loss to the Fund. In addition, the value of the debt securities in the Fund's portfolio may change on days or during time periods when shareholders will not be able to purchase or sell the Fund's shares. Authorized Participants who purchase or redeem Fund shares on days when the Fund is holding fair-valued securities may receive fewer or more shares, or lower or higher redemption proceeds, than they would have received had the Fund not fair-valued securities or used a different valuation methodology. Net asset &lt;/span&gt;&lt;span style="color:#000000;font-family:Arial;font-size:9.00pt;"&gt;value calculation may also be impacted by operational risks arising from factors such as failures in systems and technology.&lt;/span&gt;</oef:RiskTextBlock>

The Fund invests in securities &lt;/span&gt;&lt;span style="color:#000000;font-family:Arial;font-size:9.00pt;margin-left:0%;"&gt;that are traded over-the-counter or listed on an exchange. For purposes of the 80% test set forth above, securities of open-end funds, closed-end funds or other exchange-traded funds (&lt;/span&gt;&lt;span style="color:#000000;font-family:Arial;font-size:9.00pt;font-style:italic;"&gt;&#x201c;ETFs&#x201d;&lt;/span&gt;&lt;span style="color:#000000;font-family:Arial;font-size:9.00pt;"&gt;) registered under the Investment Company Act of 1940, as &lt;/span&gt;&lt;span style="color:#000000;font-family:Arial;font-size:9.00pt;margin-left:0%;"&gt;amended (the &lt;/span&gt;&lt;span style="color:#000000;font-family:Arial;font-size:9.00pt;font-style:italic;"&gt;&#x201c;1940 Act&#x201d;&lt;/span&gt;&lt;span style="color:#000000;font-family:Arial;font-size:9.00pt;"&gt;), that invest primarily in Preferred Securities or Income Securities are deemed to be Preferred Securities or Income Securities.  &lt;/span&gt;&lt;span style="color:#000000;font-family:Arial;font-size:9.00pt;margin-left:0%;"&gt;In selecting securities for the Fund, the investment strategy of the Fund&#x2019;s sub-advisor is driven by comprehensive analysis of Preferred Securities and Income Securities with a goal of investing in securities representing the best relative value in the &lt;/span&gt;&lt;span style="color:#000000;font-family:Arial;font-size:9.00pt;margin-left:0%;"&gt;market. The style of active management by the Fund&#x2019;s investment sub-advisor combines a bottom-up and top-down approach to security selection that encompasses three significant areas of analysis: credit fundamentals; relative value; and technical aspects of the securities, which may include, but are not limited to, interest rate sensitivity, call features, covenants, maturities, trading volumes, liquidity and pricing inefficiencies. The bottom-up analysis focuses on individual security analysis, idiosyncratic risks, credit fundamentals and opportunistic trading. The top-down analysis focuses on sector and industry analysis, duration and interest rate analysis, capital structure positioning and systemic risks. Diversification of the Fund portfolio within the &lt;/span&gt;&lt;span style="color:#000000;font-family:Arial;font-size:9.00pt;"&gt;Preferred Securities asset class is achieved through limits on issuer and industry weightings.  &lt;/span&gt;&lt;span style="color:#000000;font-family:Arial;font-size:9.00pt;margin-left:0%;"&gt;Preferred Securities held by the Fund generally pay fixed or adjustable-rate distributions to investors and have preference over common stock in the payment of distributions and the liquidation of a company&#x2019;s assets, but are generally junior to all forms of the company&#x2019;s debt, including both senior and subordinated debt. Certain of the Preferred Securities may be issued by trusts or other special purpose entities created by companies specifically for the purpose of issuing such securities (&lt;/span&gt;&lt;span style="color:#000000;font-family:Arial;font-size:9.00pt;font-style:italic;"&gt;&#x201c;Trust Preferred Securities&#x201d;&lt;/span&gt;&lt;span style="color:#000000;font-family:Arial;font-size:9.00pt;"&gt;).  &lt;/span&gt;&lt;span style="font-family:Arial;font-size:9.00pt;margin-left:0%;"&gt;In general, Preferred Securities held by the Fund are issued by companies in the financial, communications, consumer, government, utilities, energy, materials, industrial and technology sectors. As of December 31, &lt;/span&gt;&lt;span style="font-family:Arial;font-size:9.00pt;"&gt;2025, the market capitalization &lt;/span&gt;&lt;span style="font-family:Arial;font-size:9.00pt;margin-left:0%;"&gt;of the issuers is between $&lt;/span&gt;&lt;span style="font-family:Arial;font-size:9.00pt;"&gt;320 million and $853.3 billion. The market capitalization for the Preferred Securities is between &lt;/span&gt;&lt;span style="font-family:Arial;font-size:9.00pt;margin-left:0%;"&gt;$&lt;/span&gt;&lt;span style="font-family:Arial;font-size:9.00pt;"&gt;2.1 billion and $853.3 billion. Because the issuers of Preferred Securities are often financial companies, the Fund concentrates &lt;/span&gt;&lt;span style="font-family:Arial;font-size:9.00pt;margin-left:0%;"&gt;its investments by investing at least 25% of its total assets in the group of industries that comprise the financial sector, which may include banks, thrifts, brokerage firms, broker/dealers, investment banks, finance companies, and companies involved &lt;/span&gt;&lt;span style="font-family:Arial;font-size:9.00pt;"&gt;in the insurance industry. The Fund may also invest in preferred securities issued by real estate investment trusts (&lt;/span&gt;&lt;span style="font-family:Arial;font-size:9.00pt;font-style:italic;"&gt;&#x201c;REITs&#x201d;&lt;/span&gt;&lt;span style="font-family:Arial;font-size:9.00pt;"&gt;).  &lt;/span&gt;&lt;span style="color:#000000;font-family:Arial;font-size:9.00pt;margin-left:0%;"&gt;Income Securities held by the Fund include corporate bonds, high yield securities, commonly referred to as &lt;/span&gt;&lt;span style="color:#000000;font-family:Arial;font-size:9.00pt;font-style:italic;"&gt;&#x201c;junk&#x201d;&lt;/span&gt;&lt;span style="color:#000000;font-family:Arial;font-size:9.00pt;"&gt; bonds, and &lt;/span&gt;&lt;span style="color:#000000;font-family:Arial;font-size:9.00pt;margin-left:0%;"&gt;convertible securities. The broad category of corporate debt securities includes debt issued by U.S. and non-U.S. companies of all kinds, including those with small-, mid-and large-capitalizations. Corporate debt may carry fixed or floating rates of interest. &lt;/span&gt;&lt;span style="color:#000000;font-family:Arial;font-size:9.00pt;"&gt;The Fund may also invest in floating-rate and fixed-to-floating rate securities.  &lt;/span&gt;&lt;span style="color:#000000;font-family:Arial;font-size:9.00pt;margin-left:0%;"&gt;The Fund may invest in U.S. and non-U.S. debt and equity securities that are traded over-the-counter or listed on an exchange. The Fund may have exposure to certain emerging market countries through its investments in non-U.S. securities. The Fund may hold investments that are denominated in non-U.S. currencies, or in securities that provide exposure to such currencies, &lt;/span&gt;&lt;span style="color:#000000;font-family:Arial;font-size:9.00pt;"&gt;currency exchange rates or interest rates denominated in such currencies.  &lt;/span&gt;&lt;span style="color:#000000;font-family:Arial;font-size:9.00pt;margin-left:0%;"&gt;The average duration of the Fund&#x2019;s portfolio is expected to be between three to 12 years. Duration is a mathematical calculation of the average life of a debt security (or portfolio of debt securities) that serves as a measure of its price risk. In general, each year of duration represents an expected 1% change in the value of a security for every 1% immediate change in interest rates. For example, if the portfolio has an average duration of three years, its value can be expected to fall about 3% if interest rates rise by 1%. Conversely, the portfolio&#x2019;s value can be expected to rise about 3% if interest rates fall by 1%. As a result, prices of instruments with shorter durations tend to be less sensitive to interest rate changes than instruments with longer durations. &lt;/span&gt;&lt;span style="color:#000000;font-family:Arial;font-size:9.00pt;"&gt;As the value of a security changes over time, so will its duration.  &lt;/span&gt;&lt;span style="font-family:Arial;font-size:9.00pt;margin-left:0%;"&gt;The Fund invests at least 60% of its net assets in securities rated investment grade (BBB-/Baa3 or higher) at the time of purchase by at least one independent rating agency, such as Standard &amp;amp; Poor&#x2019;s Ratings Service, a division of The McGraw-Hill Companies,&lt;/span&gt;&lt;span style="font-family:Arial;font-size:9.00pt;"&gt; Inc., Moody&#x2019;s Investors Service, Inc., or another nationally recognized statistical rating organization (&lt;/span&gt;&lt;span style="font-family:Arial;font-size:9.00pt;font-style:italic;"&gt;"NRSRO"&lt;/span&gt;&lt;span style="font-family:Arial;font-size:9.00pt;"&gt;), &lt;/span&gt;&lt;span style="font-family:Arial;font-size:9.00pt;margin-left:0%;"&gt;and unrated securities judged to be of comparable quality by the Fund&#x2019;s sub-advisor. &lt;/span&gt;&lt;span style="font-family:Arial;font-size:9.00pt;"&gt;Additionally, for newly-issued securities, &lt;/span&gt;&lt;span style="font-family:Arial;font-size:9.00pt;margin-left:0%;"&gt;the Fund may consider an expected rating provided by an NRSRO as if it were a final rating.&lt;/span&gt;&lt;span style="font-family:Arial;font-size:9.00pt;"&gt; The Fund may invest up to 40% &lt;/span&gt;&lt;span style="font-family:Arial;font-size:9.00pt;margin-left:0%;"&gt;of its net assets in securities rated below investment grade (BB+/Ba1 or lower) at the time of purchase, which are commonly referred to as high yield securities or &#x201c;junk bonds.&#x201d; For securities with a split rating, the highest available rating will be used. In addition, at least 80% of the Fund&#x2019;s net assets are issued by issuers that have long-term issuer credit ratings of investment &lt;/span&gt;&lt;span style="font-family:Arial;font-size:9.00pt;"&gt;grade, or unrated issuers judged to be of comparable quality by the Fund&#x2019;s investment sub-advisor.  &lt;/span&gt;&lt;span style="color:#000000;font-family:Arial;font-size:9.00pt;margin-left:0%;"&gt;The Fund may invest up to 15% of its net assets in cash and/or cash equivalents. The Fund may invest in securities issued by companies domiciled in the United States, U.S. dollar-denominated depositary receipts and U.S. dollar-denominated foreign securities. The Fund may invest in Rule 144A securities, which are generally securities of U.S. and foreign issuers that are not listed on an exchange and may be (a) Preferred Securities or Income Securities issued by public companies, (b) securities of non-U.S. issuers that do not want to become subject to U.S. reporting requirements or (c) common stock by non-reporting issuers. Rule 144A securities are generally subject to resale restrictions and may be illiquid. The Fund may also invest in contingent convertible securities and hybrid capital securities. Due to the nature of certain of the Fund&#x2019;s investments, the Fund may, under certain circumstances, effect a portion of creations and redemptions for cash, rather than in-kind securities.  &lt;/span&gt;&lt;span style="font-family:Arial;font-size:9.00pt;margin-left:0%;"&gt;The Fund will concentrate its investments (&lt;/span&gt;&lt;span style="font-family:Arial;font-size:9.00pt;font-style:italic;"&gt;i.e.&lt;/span&gt;&lt;span style="font-family:Arial;font-size:9.00pt;"&gt;, invest more than 25% of Fund assets) in any of the group of industries &lt;/span&gt;&lt;span style="font-family:Arial;font-size:9.00pt;margin-left:0%;"&gt;constituting the financial sector.

The Fund is subject to the possibility that during periods of falling interest rates an issuer will call its high yielding debt securities. The Fund would then be forced to invest the proceeds at lower interest rates, likely resulting in a decline in &lt;/span&gt;&lt;span style="color:#000000;font-family:Arial;font-size:9.00pt;"&gt;the Fund&#x2019;s income.&lt;/span&gt;</oef:RiskTextBlock>

CoCos are distinct in that they are intended to either convert into equity or have their principal written down upon the occurrence of certain &#x201c;triggers.&#x201d; When an issuer&#x2019;s capital ratio falls below a specified trigger level, or in a regulator&#x2019;s discretion depending on the regulator&#x2019;s judgment about the issuer&#x2019;s solvency prospects, a CoCo may be written down, written off or converted into an equity security. Due to the contingent write-down, write-off and conversion feature, CoCos may have substantially greater risk than other securities in times of financial stress. If the trigger level is breached, the issuer's decision to write down, write off or convert a CoCo may be outside its control, and the Fund may suffer a complete loss on an investment in CoCos with no chance of recovery even if the issuer remains in existence. The value of CoCos is unpredictable and may be influenced by many factors including, without limitation: the creditworthiness of the issuer and/or fluctuations in such issuer's applicable capital ratios; supply and demand for CoCos; general market conditions and available liquidity; and economic, financial and political events that affect the issuer, its particular &lt;/span&gt;&lt;span style="color:#000000;font-family:Arial;font-size:9.00pt;"&gt;market or the financial markets in general.&lt;/span&gt;</oef:RiskTextBlock>

The value of convertible securities may rise and fall with the market value of the underlying stock or, like a debt security, vary with changes in interest rates and the credit quality of the issuer. A convertible security tends to perform more like a stock when the underlying stock price is high relative to the conversion price and more like a debt security when the underlying stock price is low relative to the conversion price.&lt;/span&gt;</oef:RiskTextBlock>

As a means to fight inflation, &lt;/span&gt;&lt;span style="font-family:Arial;font-size:9.00pt;"&gt;the Federal Reserve and &lt;/span&gt;&lt;span style="font-family:Arial;font-size:9.00pt;margin-left:0%;"&gt;certain foreign central banks have raised interest rates; however, the Federal Reserve has &lt;/span&gt;&lt;span style="font-family:Arial;font-size:9.00pt;"&gt;begun to lower interest rates and &lt;/span&gt;&lt;span style="font-family:Arial;font-size:9.00pt;margin-left:0%;"&gt;may continue to do so. U.S. regulators have proposed several changes to market and issuer regulations which would directly impact the Fund, and any regulatory changes could adversely impact the Fund&#x2019;s ability to achieve its investment strategies or make certain investments. &lt;/span&gt;&lt;span style="font-family:Arial;font-size:9.00pt;"&gt;Potential future bank failures could result in disruption to the broader banking industry or markets &lt;/span&gt;&lt;span style="font-family:Arial;font-size:9.00pt;margin-left:0%;"&gt;generally and reduce confidence in financial institutions and the economy as a whole, which may also heighten market volatility and reduce liquidity. Additionally, challenges in commercial real estate markets, including &lt;/span&gt;&lt;span style="font-family:Arial;font-size:9.00pt;"&gt;high interest rates, declining valuations &lt;/span&gt;&lt;span style="font-family:Arial;font-size:9.00pt;margin-left:0%;"&gt;and &lt;/span&gt;&lt;span style="font-family:Arial;font-size:9.00pt;"&gt;elevated vacancies, could have a broader impact on financial markets. The ongoing adversarial political climate in the &lt;/span&gt;&lt;span style="font-family:Arial;font-size:9.00pt;margin-left:0%;"&gt;United States, as well as political and diplomatic events both domestic and abroad, have and may continue to have an adverse impact the U.S. regulatory landscape, markets and investor behavior, which could have a negative impact on the Fund&#x2019;s investments and operations. The change in administration resulting from the 2024 United States national elections could result in significant impacts to international trade relations, tax and immigration policies, and other aspects of the national and international political and financial landscape, which could affect, among other things, inflation and the securities markets generally. Other unexpected political, regulatory and diplomatic events within the U.S. and abroad may affect investor and consumer confidence and may adversely impact financial markets and the broader economy. For example, ongoing armed conflicts between Russia and Ukraine in Europe and among Israel, Iran, Hamas and other militant groups in the Middle East, have caused and could continue to cause significant market disruptions and volatility within the markets in Russia, Europe, the Middle East and the United States. The hostilities and sanctions resulting from those hostilities have and could continue to have a significant impact on certain Fund investments as well as Fund performance and liquidity. The economies of the United States and its trading partners, as well as the financial markets generally, may be adversely impacted by trade disputes&lt;/span&gt;&lt;span style="font-family:Arial;font-size:9.00pt;"&gt;,  &lt;/span&gt;&lt;span style="font-family:Arial;font-size:9.00pt;margin-left:0%;"&gt;including the imposition of tariffs,&lt;/span&gt;&lt;span style="font-family:Arial;font-size:9.00pt;"&gt; and other matters. For example, the United States has imposed trade barriers and restrictions &lt;/span&gt;&lt;span style="font-family:Arial;font-size:9.00pt;margin-left:0%;"&gt;on China. In addition, the Chinese government is engaged in a longstanding dispute with Taiwan, continually threatening an invasion. If the political climate between the United States and China does not improve or continues to deteriorate, if China were to attempt invading Taiwan, or if other geopolitical conflicts develop or worsen, economies, markets and individual securities may be adversely affected, and the value of the Fund&#x2019;s assets may go down. A public health crisis and the ensuing policies enacted by governments and central banks may cause significant volatility and uncertainty in global financial markets, negatively impacting global growth prospects. As the COVID-19 global pandemic illustrated, such events may affect certain geographic regions, countries, sectors and industries more significantly than others. Advancements in technology may also adversely impact markets and the overall performance of the Fund. For instance, the economy may be significantly impacted by the advanced development and increased regulation of artificial intelligence. Additionally, cyber security breaches of both government and non-government entities could have negative impacts on infrastructure and the ability of such entities, including the Fund, to operate properly. These events, and any other future events, may adversely affect the prices and liquidity &lt;/span&gt;&lt;span style="font-family:Arial;font-size:9.00pt;"&gt;of the Fund&#x2019;s portfolio investments and could result in disruptions in the trading markets.&lt;/span&gt;</oef:RiskTextBlock>

Cyber security breaches may involve unauthorized access to the Fund&#x2019;s digital information systems through &#x201c;hacking&#x201d; or malicious software coding but may also result from outside attacks such as denial-of-service attacks through efforts to make network services unavailable to intended users. &lt;/span&gt;&lt;span style="font-family:Arial;font-size:9.00pt;"&gt;Emerging threats like ransomware or zero-day exploits could also cause disruptions to Fund operations. In addition, &lt;/span&gt;&lt;span style="font-family:Arial;font-size:9.00pt;margin-left:0%;"&gt;cyber security breaches of the issuers of securities in which the Fund invests or the Fund&#x2019;s third-party service providers, such as its administrator, transfer agent, custodian, or sub-advisor, as applicable, &lt;/span&gt;&lt;span style="font-family:Arial;font-size:9.00pt;"&gt;among many other third-party service providers,  &lt;/span&gt;&lt;span style="font-family:Arial;font-size:9.00pt;margin-left:0%;"&gt;can also subject the Fund to many of the same risks associated with direct cyber security breaches. &lt;/span&gt;&lt;span style="font-family:Arial;font-size:9.00pt;"&gt;Further, errors, misconduct, &lt;/span&gt;&lt;span style="font-family:Arial;font-size:9.00pt;margin-left:0%;"&gt;or compromise of accounts of employees of the Fund or its third-party service providers can also create material cybersecurity risks.&lt;/span&gt;&lt;span style="font-family:Arial;font-size:9.00pt;"&gt; Although the Fund has established risk management systems designed to reduce the risks associated with cyber security, &lt;/span&gt;&lt;span style="font-family:Arial;font-size:9.00pt;margin-left:0%;"&gt;there is no guarantee that such efforts will succeed, especially because the Fund does not directly control the cyber security systems of issuers or third-party service providers.&lt;/span&gt;&lt;span style="font-family:Arial;font-size:9.00pt;"&gt; Cyber security incidents may also trigger Fund obligations under data privacy &lt;/span&gt;&lt;span style="font-family:Arial;font-size:9.00pt;margin-left:0%;"&gt;laws, potentially increasing notification and compliance burdens. Cyber security incidents affecting issuers in whose securities the Fund invests may also have a negative impact on the value of the securities of such issuers, and in turn, the value of the &lt;/span&gt;&lt;span style="font-family:Arial;font-size:9.00pt;"&gt;Fund.&lt;/span&gt;</oef:RiskTextBlock>

Credit risk refers to &lt;/span&gt;&lt;span style="font-family:Arial;font-size:9.00pt;margin-left:0%;"&gt;the possibility that the issuer or other obligor of a security will not be able or willing to make payments of interest and principal when due. Generally, the value of debt securities will change inversely with changes in interest rates. To the extent that interest rates rise, certain underlying obligations may be paid off substantially slower than originally anticipated and the value of those securities may fall sharply. During periods of falling interest rates, the income received by the Fund may decline. If the principal on a debt security is prepaid before expected, the prepayments of principal may have to be reinvested in obligations paying interest at lower rates. Debt securities generally do not trade on a securities exchange making them generally less liquid and more difficult to value than common stock.&lt;/span&gt;&lt;span style="font-family:Arial;font-size:9.00pt;"&gt; Debt securities held by the Fund may be subject to amendments, waivers, or &lt;/span&gt;&lt;span style="font-family:Arial;font-size:9.00pt;margin-left:0%;"&gt;exchange offers that modify their terms. These transactions may be initiated by borrowers to address financial stress and may include exchanges of existing debt securities for new instruments with different priority, collateral, or economic characteristics. Participation in, or exclusion from, such transactions could result in the Fund holding debt that is structurally or contractually &lt;/span&gt;&lt;span style="font-family:Arial;font-size:9.00pt;"&gt;subordinated, less liquid, or of lower market value than prior to the transaction.&lt;/span&gt;</oef:RiskTextBlock>

Depositary receipts may be less liquid than the underlying shares in their primary trading market. Any distributions paid to the holders of depositary receipts are usually subject to a fee charged by the depositary. Holders of depositary receipts may have limited voting rights, and investment restrictions in certain countries may adversely impact the value of depositary receipts because such restrictions may limit the ability to convert the equity shares into depositary receipts and vice versa. Such restrictions may cause the equity shares of the underlying issuer to trade at a discount or premium to the market price &lt;/span&gt;&lt;span style="color:#000000;font-family:Arial;font-size:9.00pt;"&gt;of the depositary receipts.&lt;/span&gt;</oef:RiskTextBlock>

Investments in emerging markets securities are generally considered speculative in nature and are subject to the following heightened risks: smaller market capitalization of securities markets which may suffer periods of relative illiquidity; significant price volatility; restrictions on foreign investment; possible repatriation of investment income and capital; rapid inflation; and currency convertibility issues. Emerging market countries also often have less uniformity in accounting, auditing and reporting requirements, unsettled securities laws, unreliable securities valuation and greater risk associated with custody of securities. Financial and other reporting by companies and government entities also may be less reliable in emerging market countries. Shareholder claims that are available in the U.S., as well as regulatory oversight and authority that is common in the U.S., including for claims based on fraud, may be difficult or impossible for shareholders of securities in emerging market countries or for U.S. authorities to pursue. Furthermore, investors may be required to register the proceeds of sales and future economic or political crises could lead to price controls, forced mergers, expropriation or confiscatory taxation, seizure, nationalization &lt;/span&gt;&lt;span style="color:#000000;font-family:Arial;font-size:9.00pt;"&gt;or creation of government monopolies.&lt;/span&gt;</oef:RiskTextBlock>

Equity securities may decline significantly in price over short or extended periods of time, and such declines may occur in the equity market as a whole, or they may occur in only a particular country, &lt;/span&gt;&lt;span style="color:#000000;font-family:Arial;font-size:9.00pt;"&gt;company, industry or sector of the market.&lt;/span&gt;</oef:RiskTextBlock>

In these member states, the authority to direct monetary policies, including money supply and official interest rates for the Euro, is exercised by the European Central Bank. In a 2016 referendum, the United Kingdom elected to withdraw from the EU (&lt;/span&gt;&lt;span style="color:#000000;font-family:Arial;font-size:9.00pt;font-style:italic;"&gt;&#x201c;Brexit&#x201d;&lt;/span&gt;&lt;span style="color:#000000;font-family:Arial;font-size:9.00pt;"&gt;). After years of negotiations between the United Kingdom and the EU, a withdrawal &lt;/span&gt;&lt;span style="color:#000000;font-family:Arial;font-size:9.00pt;margin-left:0%;"&gt;agreement was reached whereby the United Kingdom formally left the EU. As the second largest economy among EU members, the implications of the United Kingdom&#x2019;s withdrawal are difficult to gauge and cannot be fully known. Its departure may negatively impact the EU and Europe as a whole by causing volatility within the EU, triggering prolonged economic downturns in certain European countries or sparking additional member states to contemplate departing the EU (thereby perpetuating &lt;/span&gt;&lt;span style="color:#000000;font-family:Arial;font-size:9.00pt;"&gt;political instability in the region).&lt;/span&gt;</oef:RiskTextBlock>

As a result, the coupon on floating rate securities will generally decline in a falling interest rate environment, causing the Fund to experience a reduction in the income it receives from the security. A floating rate security&#x2019;s coupon rate resets periodically according to the terms of the security. Consequently, in a rising interest rate environment, floating rate securities with coupon rates that reset infrequently may lag behind the changes in market interest rates. Floating rate securities may also contain terms that impose a maximum coupon rate the issuer will pay, regardless of &lt;/span&gt;&lt;span style="color:#000000;font-family:Arial;font-size:9.00pt;"&gt;the level of the reference rate which would decrease the value of the security.&lt;/span&gt;</oef:RiskTextBlock>

Interest rate risk is generally lower for shorter term debt securities and higher for longer-term debt securities. The Fund may be subject to a greater risk of rising interest rates than would normally be the case during periods of low interest rates. Duration is a reasonably accurate measure of a debt security&#x2019;s price sensitivity to changes in interest rates and a common measure of interest rate risk. Duration measures a debt security&#x2019;s expected life on a present value basis, taking into account the debt security&#x2019;s yield, interest payments and final maturity. In general, duration represents the expected percentage change in the value of a security for an immediate 1% change in interest rates. For example, the price of a debt security with a three-year duration would be expected to drop by approximately 3% in response to a 1% increase in interest rates. Therefore, prices of debt securities with shorter durations tend to be less sensitive to interest rate changes than debt securities with longer durations. Higher sensitivity to interest rates is generally correlated with higher levels of &lt;/span&gt;&lt;span style="color:#000000;font-family:Arial;font-size:9.00pt;"&gt;volatility and, therefore, greater risk. As the value of a debt security changes over time, so will its duration.&lt;/span&gt;</oef:RiskTextBlock>

Generally, holders of preferred securities have no voting rights with respect to the issuing company unless preferred dividends have been in arrears for a specified number of periods, at which time the preferred security holders may obtain limited rights. In certain circumstances, an issuer of preferred securities may defer payment on the securities and, in some cases, redeem the securities prior to a &lt;/span&gt;&lt;span style="color:#000000;font-family:Arial;font-size:9.00pt;"&gt;specified date.

The Fund&#x2019;s investment advisor cannot predict whether shares will trade below, at or above their net asset value because the shares trade on the Exchange at market prices and not at net asset value. Price differences may be due, in large part, to the fact that supply and demand forces at work in the secondary trading market for shares will be closely related, but not identical, to the same forces influencing the prices of the holdings of the Fund trading individually or in the aggregate at any point in time. However, given that shares can only be purchased and redeemed in Creation Units, and only to and from broker-dealers and large institutional investors that have entered into participation agreements (unlike shares of closed-end funds, which frequently trade at appreciable discounts from, and sometimes at premiums to, their net asset value), the Fund&#x2019;s investment advisor believes that large discounts or premiums to the net asset value of shares should not be sustained. During stressed market conditions, the market for the Fund&#x2019;s shares may become less liquid in response to deteriorating liquidity in the market for the Fund&#x2019;s underlying portfolio holdings, which could in turn lead to differences between the market price of the Fund&#x2019;s shares and their net asset &lt;/span&gt;&lt;span style="color:#000000;font-family:Arial;font-size:9.00pt;"&gt;value and the bid/ask spread on the Fund&#x2019;s shares may widen.&lt;/span&gt;</oef:RiskTextBlock>

As a result, investments in REITs are subject to the risks associated with investing in real estate, which may include, but are not limited to: fluctuations in the value of underlying properties; defaults by borrowers or tenants; market saturation; changes in general and local operating expenses; and other economic, political or regulatory occurrences affecting companies in the real estate sector. REITs are also subject to the risk that the real estate market may experience an economic downturn generally, which may have a material effect on the real estate in which the REITs invest and their underlying portfolio securities. REITs may have also a relatively small market capitalization which may result in their shares experiencing less market liquidity and greater price volatility than larger companies. Increases in interest rates typically lower the present value of a REIT's future earnings stream, and may make financing property purchases and improvements more costly. Because the market price of REIT stocks may change based upon investors' collective perceptions of future &lt;/span&gt;&lt;span style="color:#000000;font-family:Arial;font-size:9.00pt;"&gt;earnings, the value of the Fund will generally decline when investors anticipate or experience rising interest rates.&lt;/span&gt;</oef:RiskTextBlock>

Developed market companies are those companies (i) whose &lt;/span&gt;&lt;span style="color:#000000;font-family:Arial;font-size:9.00pt;margin-left:0%;"&gt;securities are traded principally on a stock exchange in a developed market country, (ii) that have a primary business office in a developed market country, or (iii) that have at least 50% of their assets in, or derive at least 50% of their revenues or profits from, a developed market country. Developed market countries currently include the countries comprising the Morgan Stanley Capital International World Index or countries considered to be developed by the World Bank, the International Finance Corporation or the United Nations. Under normal market conditions, the Fund will invest in at least three countries and at &lt;/span&gt;&lt;span style="color:#000000;font-family:Arial;font-size:9.00pt;margin-left:0%;"&gt;least 40% of its net assets in countries other than the United States. The securities in which the Fund may invest must be &lt;/span&gt;&lt;span style="color:#000000;font-family:Arial;font-size:9.00pt;"&gt;listed on a U.S. or non-U.S. securities exchange. The Fund may invest in small, mid and large capitalization companies.  &lt;/span&gt;&lt;span style="color:#000000;font-family:Arial;font-size:9.00pt;margin-left:0%;"&gt;The Fund utilizes a dynamic currency hedging strategy through the use of forward foreign currency exchange contracts and currency spot transactions to hedge up to 100% of the Fund&#x2019;s currency exposure. As a result of this hedging strategy, the portion of the Fund&#x2019;s portfolio securities which are subject to currency hedging transactions may vary widely, from 0% to 100% of the portfolio securities. A forward contract on foreign currency is an obligation to purchase or sell a specific currency at a future date, which may be any fixed number of days agreed upon by the parties from the date of the contract, at a price set on the date of the contract. A forward foreign currency exchange contract may reduce the Fund&#x2019;s exposure to changes in the value of the currency it will deliver and increase its exposure to changes in the value of the currency it will receive for the duration of the contract. The effect on the value of the Fund is similar to selling securities denominated in one currency and purchasing securities denominated in another currency. The Fund also may enter into currency spot transactions as part of its dynamic currency hedging strategy. A currency spot transaction is an agreement between two parties to buy or sell a specific currency for delivery on a date that is typically two business days from the date of the agreement, as opposed to a date set in the future. The underlying currencies of the forward foreign currency exchange contracts and currency spot transactions included in the Fund&#x2019;s policy relating to the investment of at least 80% of its net assets (including investment &lt;/span&gt;&lt;span style="color:#000000;font-family:Arial;font-size:9.00pt;"&gt;borrowings) will be limited to Developed Market currencies.  &lt;/span&gt;&lt;span style="color:#000000;font-family:Arial;font-size:9.00pt;margin-left:0%;"&gt;The Fund also may invest up to 20% of its net assets in companies of emerging market countries and forward foreign currency exchange contracts and currency spot transactions used to hedge the Fund&#x2019;s exposure to non-Developed Market currencies as well as any proxy currency hedging transactions involving non-Developed Market currencies determined to be representative of, and serve as a proxy for, Developed Market currencies. Such emerging market companies are companies (i) whose securities are traded principally on a stock exchange in a country that is not a developed market country, (ii) that have a primary business office in a country that is not a developed market country, or (iii) that have at least 50% of their assets in, or derive at least 50% of their revenues or profits from, a country that is not a developed market country. The equity securities of emerging market companies in which the Fund may invest include investments in common stock, depositary receipts and common and &lt;/span&gt;&lt;span style="color:#000000;font-family:Arial;font-size:9.00pt;"&gt;preferred shares of REITs.  &lt;/span&gt;&lt;span style="color:#000000;font-family:Arial;font-size:9.00pt;margin-left:0%;"&gt;In selecting the portfolio securities of the Fund, RiverFront Investment Group, LLC, the Fund&#x2019;s sub-advisor (&lt;/span&gt;&lt;span style="color:#000000;font-family:Arial;font-size:9.00pt;font-style:italic;"&gt;&#x201c;RIG&#x201d;&lt;/span&gt;&lt;span style="color:#000000;font-family:Arial;font-size:9.00pt;"&gt; or the &lt;/span&gt;&lt;span style="color:#000000;font-family:Arial;font-size:9.00pt;font-style:italic;margin-left:0%;"&gt;&#x201c;Sub-Advisor&#x201d;&lt;/span&gt;&lt;span style="color:#000000;font-family:Arial;font-size:9.00pt;"&gt;), assembles a portfolio of eligible countries and/or securities based on several core attributes, including, but &lt;/span&gt;&lt;span style="color:#000000;font-family:Arial;font-size:9.00pt;margin-left:0%;"&gt;not limited to, value, quality and momentum. The Sub-Advisor considers multiple factors within each core attribute, such as the price-to-book value of a security when determining value and a company&#x2019;s cash as a percentage of the company&#x2019;s market capitalization when determining quality. The Sub-Advisor then assigns each qualifying security a score based on its core attributes and selects the individual securities with the highest scores for investment. In doing so, the Sub-Advisor utilizes its proprietary optimization process to maximize the percentage of high-scoring securities included in the portfolio in accordance with country, sector and risk factor (&lt;/span&gt;&lt;span style="color:#000000;font-family:Arial;font-size:9.00pt;font-style:italic;"&gt;e.g.&lt;/span&gt;&lt;span style="color:#000000;font-family:Arial;font-size:9.00pt;"&gt;, beta, quality, volatility) limitations, subject to the Sub-Advisor's &lt;/span&gt;&lt;span style="color:#000000;font-family:Arial;font-size:9.00pt;margin-left:0%;"&gt;fundamental active overlay. The Sub-Advisor also considers the market capitalization of the companies in which the Fund may invest, and the trading volume of a company&#x2019;s shares in the secondary market. The strategy is largely quantitative and rules-based, but also includes multiple parameters over which the Sub-Advisor may exercise discretion (including, but not limited to, the number of holdings and the weightings of particular holdings) in connection with its active management of &lt;/span&gt;&lt;span style="color:#000000;font-family:Arial;font-size:9.00pt;"&gt;the Fund.  &lt;/span&gt;&lt;span style="color:#000000;font-family:Arial;font-size:9.00pt;margin-left:0%;"&gt;In managing the Fund&#x2019;s currency exposure, the Sub-Advisor deploys a dynamic currency hedging strategy based on a proprietary hedging methodology that considers a combination of quantitative measures, such as interest rate differentials, central bank balance sheet expansion/contraction and price momentum, and qualitative measures, such as formal and informal guidance &lt;/span&gt;&lt;span style="color:#000000;font-family:Arial;font-size:9.00pt;"&gt;from central bankers.  &lt;/span&gt;&lt;span style="color:#000000;font-family:Arial;font-size:9.00pt;margin-left:0%;"&gt;To the extent permitted under applicable law, percentage limitations described in this prospectus are generally as of the time of investment by the Fund and may be exceeded on a going-forward basis as a result of market fluctuations affecting the &lt;/span&gt;&lt;span style="color:#000000;font-family:Arial;font-size:9.00pt;"&gt;Fund&#x2019;s portfolio securities.  &lt;/span&gt;&lt;span style="font-family:Arial;font-size:9.00pt;margin-left:0%;"&gt;As of January 30, 2026, the Fund had significant investments in financial companies, Japanese issuers, UK issuers, Asian issuers and European issuers, although this may change from time to time.&lt;/span&gt;&lt;span style="font-family:Arial;font-size:9.00pt;"&gt; Over time, the Fund may have significant investments in &lt;/span&gt;&lt;span style="font-family:Arial;font-size:9.00pt;margin-left:0%;"&gt;a jurisdiction, investment sector or industry or group of industries that it may not have had as of January 30, 2026.

Many &lt;/span&gt;&lt;span style="color:#000000;font-family:Arial;font-size:9.00pt;margin-left:0%;"&gt;Asian economies have experienced rapid growth and industrialization, and there is no assurance that this growth rate will be maintained. Some Asian economies are highly dependent on trade, and economic conditions in other countries within and outside Asia can impact these economies. Certain of these economies may be adversely affected by trade or policy disputes with its major trade partners. There is also a high concentration of market capitalization and trading volume in a small number of issuers representing a limited number of industries, as well as a high concentration of investors and financial intermediaries. Certain Asian countries have experienced and may in the future experience expropriation and nationalization of assets, confiscatory taxation, currency manipulation, political instability, armed conflict and social instability as a result of religious, ethnic, socio-economic and/or political unrest. In particular, escalated tensions involving North Korea and any outbreak of hostilities involving North Korea could have a severe adverse effect on Asian economies. Governments of certain Asian countries have exercised, and continue to exercise, substantial influence over many aspects of the private sector. In certain cases, the government owns or controls many companies, including the largest in the country. Accordingly, government actions could have a significant effect on the issuers of the Fund&#x2019;s securities or on economic conditions generally. Recent developments in relations between the U.S. and China have heightened concerns of increased tariffs and restrictions on trade between the two countries. An increase in tariffs or trade restrictions, or even the threat of such developments, could lead to a significant reduction in international trade, which could have a negative impact on the economy of Asian countries and a commensurately &lt;/span&gt;&lt;span style="color:#000000;font-family:Arial;font-size:9.00pt;"&gt;negative impact on the Fund.&lt;/span&gt;</oef:RiskTextBlock>

As a means to fight inflation, &lt;/span&gt;&lt;span style="font-family:Arial;font-size:9.00pt;"&gt;the Federal Reserve and &lt;/span&gt;&lt;span style="font-family:Arial;font-size:9.00pt;margin-left:0%;"&gt;certain foreign central banks have raised interest rates; however, the Federal Reserve has &lt;/span&gt;&lt;span style="font-family:Arial;font-size:9.00pt;"&gt;begun to lower interest rates and &lt;/span&gt;&lt;span style="font-family:Arial;font-size:9.00pt;margin-left:0%;"&gt;may continue to do so. U.S. regulators have proposed several changes to market and issuer regulations which would directly impact the Fund, and any regulatory changes could adversely impact the Fund&#x2019;s ability to achieve its investment strategies or make certain investments. &lt;/span&gt;&lt;span style="font-family:Arial;font-size:9.00pt;"&gt;Potential future bank failures could result in disruption to the broader banking industry or markets &lt;/span&gt;&lt;span style="font-family:Arial;font-size:9.00pt;margin-left:0%;"&gt;generally and reduce confidence in financial institutions and the economy as a whole, which may also heighten market volatility and reduce liquidity. Additionally, challenges in commercial real estate markets, including &lt;/span&gt;&lt;span style="font-family:Arial;font-size:9.00pt;"&gt;high interest rates, declining valuations &lt;/span&gt;&lt;span style="font-family:Arial;font-size:9.00pt;margin-left:0%;"&gt;and &lt;/span&gt;&lt;span style="font-family:Arial;font-size:9.00pt;"&gt;elevated vacancies, could have a broader impact on financial markets. The ongoing adversarial political climate in the &lt;/span&gt;&lt;span style="font-family:Arial;font-size:9.00pt;margin-left:0%;"&gt;United States, as well as political and diplomatic events both domestic and abroad, have and may continue to have an adverse impact the U.S. regulatory landscape, markets and investor behavior, which could have a negative impact on the Fund&#x2019;s investments and operations. The change in administration resulting from the 2024 United States national elections could result in significant impacts to international trade relations, tax and immigration policies, and other aspects of the national and international political and financial landscape, which could affect, among other things, inflation and the securities markets generally. Other unexpected political, regulatory and diplomatic events within the U.S. and abroad may affect investor and consumer confidence and may adversely impact financial markets and the broader economy. For example, ongoing armed conflicts between Russia and Ukraine in Europe and among Israel, Iran, Hamas and other militant groups in the Middle East, have caused and could continue to cause significant market disruptions and volatility within the markets in Russia, Europe, the Middle East and the United States. The hostilities and sanctions resulting from those hostilities have and could continue to have a significant impact on certain Fund investments as well as Fund performance and liquidity. The economies of the United States and its trading partners, as well as the financial markets generally, may be adversely impacted by trade disputes&lt;/span&gt;&lt;span style="font-family:Arial;font-size:9.00pt;"&gt;,  &lt;/span&gt;&lt;span style="font-family:Arial;font-size:9.00pt;margin-left:0%;"&gt;including the imposition of tariffs,&lt;/span&gt;&lt;span style="font-family:Arial;font-size:9.00pt;"&gt; and other matters. For example, the United States has imposed trade barriers and restrictions &lt;/span&gt;&lt;span style="font-family:Arial;font-size:9.00pt;margin-left:0%;"&gt;on China. In addition, the Chinese government is engaged in a longstanding dispute with Taiwan, continually threatening an invasion. If the political climate between the United States and China does not improve or continues to deteriorate, if China were to attempt invading Taiwan, or if other geopolitical conflicts develop or worsen, economies, markets and individual securities may be adversely affected, and the value of the Fund&#x2019;s assets may go down. A public health crisis and the ensuing policies enacted by governments and central banks may cause significant volatility and uncertainty in global financial markets, negatively impacting global growth prospects. As the COVID-19 global pandemic illustrated, such events may affect certain geographic regions, countries, sectors and industries more significantly than others. Advancements in technology may also adversely impact markets and the overall performance of the Fund. For instance, the economy may be significantly impacted by the advanced development and increased regulation of artificial intelligence. Additionally, cyber security breaches of both government and non-government entities could have negative impacts on infrastructure and the ability of such entities, including the Fund, to operate properly. These events, and any other future events, may adversely affect the prices and liquidity &lt;/span&gt;&lt;span style="font-family:Arial;font-size:9.00pt;"&gt;of the Fund&#x2019;s portfolio investments and could result in disruptions in the trading markets.&lt;/span&gt;</oef:RiskTextBlock>

A breach in cyber security refers to both intentional and unintentional events that may cause the Fund to lose proprietary information, suffer data corruption or lose operational capacity&lt;/span&gt;&lt;span style="font-family:Arial;font-size:9.00pt;"&gt;, any of which could result in a material adverse &lt;/span&gt;&lt;span style="font-family:Arial;font-size:9.00pt;margin-left:0%;"&gt;effect on the Fund or its shareholders&lt;/span&gt;&lt;span style="font-family:Arial;font-size:9.00pt;"&gt;. Such events could cause the Fund to incur regulatory penalties, reputational damage, &lt;/span&gt;&lt;span style="font-family:Arial;font-size:9.00pt;margin-left:0%;"&gt;additional compliance costs associated with corrective measures and/or financial loss. Cyber security breaches may involve unauthorized access to the Fund&#x2019;s digital information systems through &#x201c;hacking&#x201d; or malicious software coding but may also result from outside attacks such as denial-of-service attacks through efforts to make network services unavailable to intended users. &lt;/span&gt;&lt;span style="font-family:Arial;font-size:9.00pt;"&gt;Emerging threats like ransomware or zero-day exploits could also cause disruptions to Fund operations. In addition, &lt;/span&gt;&lt;span style="font-family:Arial;font-size:9.00pt;margin-left:0%;"&gt;cyber security breaches of the issuers of securities in which the Fund invests or the Fund&#x2019;s third-party service providers, such as its administrator, transfer agent, custodian, or sub-advisor, as applicable, &lt;/span&gt;&lt;span style="font-family:Arial;font-size:9.00pt;"&gt;among many other third-party service providers,  &lt;/span&gt;&lt;span style="font-family:Arial;font-size:9.00pt;margin-left:0%;"&gt;can also subject the Fund to many of the same risks associated with direct cyber security breaches. &lt;/span&gt;&lt;span style="font-family:Arial;font-size:9.00pt;"&gt;Further, errors, misconduct, &lt;/span&gt;&lt;span style="font-family:Arial;font-size:9.00pt;margin-left:0%;"&gt;or compromise of accounts of employees of the Fund or its third-party service providers can also create material cybersecurity risks.&lt;/span&gt;&lt;span style="font-family:Arial;font-size:9.00pt;"&gt; Although the Fund has established risk management systems designed to reduce the risks associated with cyber security, &lt;/span&gt;&lt;span style="font-family:Arial;font-size:9.00pt;margin-left:0%;"&gt;there is no guarantee that such efforts will succeed, especially because the Fund does not directly control the cyber security systems of issuers or third-party service providers.&lt;/span&gt;&lt;span style="font-family:Arial;font-size:9.00pt;"&gt; Cyber security incidents may also trigger Fund obligations under data privacy &lt;/span&gt;&lt;span style="font-family:Arial;font-size:9.00pt;margin-left:0%;"&gt;laws, potentially increasing notification and compliance burdens. Cyber security incidents affecting issuers in whose securities the Fund invests may also have a negative impact on the value of the securities of such issuers, and in turn, the value of the &lt;/span&gt;&lt;span style="font-family:Arial;font-size:9.00pt;"&gt;Fund.&lt;/span&gt;</oef:RiskTextBlock>

These risks include or may include: (i) the risk that the value of the underlying assets may go up or down; (ii) the risk that the counterparty to a derivative transaction may not fulfill its contractual obligations; (iii) the risk of mispricing or improper valuation of a derivative; (iv) the risk that changes in the &lt;/span&gt;&lt;span style="color:#000000;font-family:Arial;font-size:9.00pt;margin-left:0%;"&gt;value of the derivative may not correlate perfectly with the underlying asset; (v) the risk that a derivative instrument cannot be sold, closed out or replaced quickly at or very close to its fundamental value; (vi) the risk of loss caused by the unenforceability of a party&#x2019;s obligations under the derivative; and (vii) the risk that a disruption in the financial markets will cause difficulties for all market participants. Derivative prices are highly volatile and may fluctuate substantially during a short period of time. Such prices are influenced by numerous factors that affect the markets, including, but not limited to: changing supply and demand relationships; government programs and policies; national and international political and economic events, changes in interest rates, inflation and deflation and changes in supply and demand relationships. Trading derivative instruments involves risks different from, or possibly greater than, the risks associated with investing directly in securities. Derivative contracts ordinarily have leverage inherent in their terms. The low margin deposits normally required in trading derivatives, including futures contracts, permit a high degree of leverage. Accordingly, a relatively small price movement may result in an immediate and substantial loss. The use of leverage may also cause the Fund to liquidate portfolio positions when it would not be advantageous to do so. The use of leveraged derivatives can magnify potential for gain or loss and, therefore, amplify the &lt;/span&gt;&lt;span style="color:#000000;font-family:Arial;font-size:9.00pt;"&gt;effects of market volatility on share price.&lt;/span&gt;</oef:RiskTextBlock>

As such, contracts to sell foreign currency will generally be expected to limit any potential gain that might be realized by the Fund if the value of the hedged currency increases. In addition, the use of currency hedging will not necessarily eliminate exposure to all currency fluctuations. Hedging against a decline in the value of a currency does not eliminate fluctuations in the value of a portfolio security traded in that currency or prevent a loss if the value of the security declines. Moreover, it may not be possible for the Fund to hedge against a devaluation that is so generally anticipated that the Fund is not able to contract &lt;/span&gt;&lt;span style="color:#000000;font-family:Arial;font-size:9.00pt;"&gt;to sell the currency at a price above the devaluation level it anticipates.&lt;/span&gt;</oef:RiskTextBlock>

Equity securities prices fluctuate for several reasons, including changes in investors&#x2019; perceptions of the financial condition of an issuer or the general condition of the relevant equity market, such as market volatility, or when political or economic events affecting an issuer occur. Common stock prices may be particularly sensitive to rising interest rates, as the cost of capital rises and borrowing costs increase. Equity securities may decline significantly in price over short or extended periods of time, and such declines may occur in the equity market as a whole, or they may occur in only a particular country, &lt;/span&gt;&lt;span style="font-family:Arial;font-size:9.00pt;"&gt;company, industry or sector of the market.&lt;/span&gt;</oef:RiskTextBlock>

A significant number of countries in Europe are member states in the European Union (the &lt;/span&gt;&lt;span style="color:#000000;font-family:Arial;font-size:9.00pt;font-style:italic;"&gt;&#x201c;EU&#x201d;&lt;/span&gt;&lt;span style="color:#000000;font-family:Arial;font-size:9.00pt;"&gt;), and the member states no longer control their own monetary policies by directing independent &lt;/span&gt;&lt;span style="color:#000000;font-family:Arial;font-size:9.00pt;margin-left:0%;"&gt;interest rates for their currencies. In these member states, the authority to direct monetary policies, including money supply and official interest rates for the Euro, is exercised by the European Central Bank. In a 2016 referendum, the United Kingdom elected to withdraw from the EU (&lt;/span&gt;&lt;span style="color:#000000;font-family:Arial;font-size:9.00pt;font-style:italic;"&gt;&#x201c;Brexit&#x201d;&lt;/span&gt;&lt;span style="color:#000000;font-family:Arial;font-size:9.00pt;"&gt;).

As the second largest economy among EU members, the implications of the United Kingdom&#x2019;s withdrawal are difficult to gauge and cannot be fully known. Its departure may negatively impact the EU and Europe as a whole by causing volatility within the EU, triggering prolonged economic downturns in certain European countries or sparking additional member states to contemplate departing the EU (thereby perpetuating &lt;/span&gt;&lt;span style="color:#000000;font-family:Arial;font-size:9.00pt;"&gt;political instability in the region).&lt;/span&gt;</oef:RiskTextBlock>

A relatively small price movement in a forward contract may result in substantial losses to the Fund, exceeding the amount of the margin paid. Forward contracts can increase the Fund&#x2019;s risk exposure to underlying references and their attendant risks, such as credit &lt;/span&gt;&lt;span style="color:#000000;font-family:Arial;font-size:9.00pt;margin-left:0%;"&gt;risk, currency risk, market risk, and interest rate risk, while also exposing the Fund to counterparty risk, liquidity risk and &lt;/span&gt;&lt;span style="color:#000000;font-family:Arial;font-size:9.00pt;"&gt;valuation risk, among others.&lt;/span&gt;</oef:RiskTextBlock>

There are no limitations on daily price moves in such forward contracts, and banks and dealers are not required to continue to make markets in such contracts. There have been periods during which certain banks or dealers have refused to quote prices for such forward contracts or have quoted prices with an unusually wide spread between the price at which the bank or dealer is prepared to buy and that at which it is prepared to sell. Governmental imposition of credit controls might limit any such forward contract trading. Forward foreign currency exchange contracts involve certain risks, including the risk of failure of the counterparty to perform its obligations under the contract and the risk that the use of forward contracts may not serve as a complete hedge because of an imperfect correlation between movements in the prices of the contracts and the prices of the currencies hedged. Forward foreign currency exchange contracts may limit any potential gain that might result should the value of the underlying currencies increase. In addition, because forward currency exchange contracts are privately negotiated transactions, there can be no assurance that the Fund &lt;/span&gt;&lt;span style="color:#000000;font-family:Arial;font-size:9.00pt;"&gt;will have flexibility to roll-over a forward foreign currency exchange contract upon its expiration if it desires to do so.&lt;/span&gt;</oef:RiskTextBlock>

Japan&#x2019;s economy is characterized by government intervention and protectionism, reliance on oil imports, an unstable financial services sector and relatively high unemployment. Since 2000, Japan has experienced relatively low economic growth, and it may remain low in the future. Its economy is heavily dependent on international trade and has been adversely affected by trade tariffs and competition from emerging economies. As such, economic growth is heavily dependent on continued growth in international trade, relatively low commodities prices, government support of the financial services sector and other government policies. Any changes or trends in these economic factors could have a significant impact on Japanese markets overall and may negatively affect the Fund's investments. Japan&#x2019;s economy and equity market also share a strong correlation with U.S. markets and the Japanese economy may be affected by economic problems in the U.S. Despite a strengthening in the economic relationship between Japan and China, the countries&#x2019; political relationship has at times been strained. Should political tension increase, it could adversely affect the economy and destabilize the region as a whole. Additionally, escalated tensions involving North Korea and any outbreak of hostilities involving North Korea could have a severe adverse effect on Japan&#x2019;s economy. Japan&#x2019;s geography also subjects it to an increased risk of natural disasters, such as earthquakes, volcanic eruptions, typhoons and tsunamis, all of which could negatively impact &lt;/span&gt;&lt;span style="color:#000000;font-family:Arial;font-size:9.00pt;"&gt;the Fund's investments.&lt;/span&gt;</oef:RiskTextBlock>

In managing the &lt;/span&gt;&lt;span style="color:#000000;font-family:Arial;font-size:9.00pt;margin-left:0%;"&gt;Fund&#x2019;s investment portfolio, the Sub-Advisor will apply investment techniques and risk analyses that may not have the desired &lt;/span&gt;&lt;span style="color:#000000;font-family:Arial;font-size:9.00pt;"&gt;result. There can be no guarantee that the Fund will meet its investment objective.  &lt;/span&gt;&lt;span style="color:#000000;font-family:Arial;font-size:9.00pt;margin-left:0%;"&gt;The Sub-Advisor specializes in managing asset allocation portfolios, which invest in various investment vehicles, including the Fund and other exchange-traded funds (&lt;/span&gt;&lt;span style="color:#000000;font-family:Arial;font-size:9.00pt;font-style:italic;"&gt;&#x201c;ETFs&#x201d;&lt;/span&gt;&lt;span style="color:#000000;font-family:Arial;font-size:9.00pt;"&gt;), to obtain targeted amounts of exposure to different asset classes. The &lt;/span&gt;&lt;span style="color:#000000;font-family:Arial;font-size:9.00pt;margin-left:0%;"&gt;Fund was developed to serve as, and will serve as, an investment vehicle for such asset allocation portfolios. As the manager of the Fund and the portfolios, the Sub-Advisor is likely to encounter conflicts of interest. For example, the Sub-Advisor may need to reduce its asset allocation portfolios&#x2019; exposure to an asset class to which the portfolios obtain exposure by investing in the Fund. Under such circumstances, the Sub-Advisor would liquidate some or all of the portfolios&#x2019; investments in the Fund, &lt;/span&gt;&lt;span style="color:#000000;font-family:Arial;font-size:9.00pt;"&gt;which could adversely affect the Fund.&lt;/span&gt;</oef:RiskTextBlock>

Decisions by market makers or authorized participants to reduce their &lt;/span&gt;&lt;span style="font-family:Arial;font-size:9.00pt;margin-left:0%;"&gt;role or step away from these activities in times of market stress could inhibit the effectiveness of the arbitrage process in maintaining the relationship between the underlying values of the Fund&#x2019;s portfolio securities and the Fund&#x2019;s market price. The Fund may rely on a small number of third-party market makers to provide a market for the purchase and sale of shares. Any trading halt or other problem relating to the trading activity of these market makers could result in a dramatic change in the spread between the Fund&#x2019;s net asset value and the price at which the Fund&#x2019;s shares are trading on the Exchange, which could result in a decrease in value of the Fund&#x2019;s shares. This reduced effectiveness could result in Fund shares trading at a &lt;/span&gt;&lt;span style="font-family:Arial;font-size:9.00pt;"&gt;discount to net asset value and also in greater than normal intraday bid-ask spreads for Fund shares.&lt;/span&gt;</oef:RiskTextBlock>

Securities &lt;/span&gt;&lt;span style="color:#000000;font-family:Arial;font-size:9.00pt;margin-left:0%;"&gt;are subject to market fluctuations caused by real or perceived adverse economic, political, and regulatory factors or market developments, changes in interest rates and perceived trends in securities prices. Shares of the Fund could decline in value or underperform other investments.

To the extent that the model is based upon incorrect or incomplete data, the Fund could be induced to buy certain investments at prices that are too high, to sell certain other investments at prices that are too low or to miss favorable opportunities altogether.

However, because OTC derivatives do not trade on an exchange, the parties to an OTC derivative face heightened levels of counterparty risk, liquidity risk and valuation risk. To the extent that the Fund utilizes OTC derivatives, its counterparty risk will be higher if it only trades with a single or small number of counterparties. The secondary market for OTC derivatives may not be as deep as for other instruments and such &lt;/span&gt;&lt;span style="color:#000000;font-family:Arial;font-size:9.00pt;"&gt;instruments may experience periods of illiquidity.

Generally, holders of preferred securities have no voting rights with respect to the issuing company unless preferred dividends have been in arrears for a specified number of periods, at which time the preferred security holders may obtain limited rights. In certain circumstances, an issuer of preferred securities may defer payment on the securities and, in some cases, redeem the securities prior to a &lt;/span&gt;&lt;span style="color:#000000;font-family:Arial;font-size:9.00pt;"&gt;specified date.

The Fund&#x2019;s investment advisor cannot predict whether shares will trade below, at or above their net asset value because the shares trade on the Exchange at market prices and not at net asset value. Price differences may be due, in large part, to the fact that supply and demand forces at work in the secondary trading market for shares will be closely related, but not identical, to the same forces influencing the prices of the holdings of the Fund trading individually or in the aggregate at any point in time. However, given that shares can only be purchased and redeemed in Creation Units, and only to and from broker-dealers and large institutional investors that have entered into participation agreements (unlike shares of closed-end funds, which frequently trade at appreciable discounts from, and sometimes at premiums to, their net asset value), the Fund&#x2019;s investment advisor believes that large discounts or premiums to the net asset value of shares should not be sustained. During stressed market conditions, the market for the Fund&#x2019;s shares may become less liquid in response to deteriorating liquidity in the market for the Fund&#x2019;s underlying portfolio holdings, which could in turn lead to differences between the market price of the Fund&#x2019;s shares and their net asset &lt;/span&gt;&lt;span style="color:#000000;font-family:Arial;font-size:9.00pt;"&gt;value and the bid/ask spread on the Fund&#x2019;s shares may widen.&lt;/span&gt;</oef:RiskTextBlock>

As a result, investments in REITs are subject to the risks associated with investing in real estate, which may include, but are not limited to: fluctuations in the value of underlying properties; defaults by borrowers or tenants; market saturation; changes in general and local operating expenses; and other economic, political or regulatory occurrences affecting companies in the real estate sector. REITs are also subject to the risk that the real estate market may experience an economic downturn generally, which may have a material effect on the real estate in which the REITs invest and their underlying portfolio securities. REITs may have also a relatively small market capitalization which may result in their shares experiencing less market liquidity and greater price volatility than larger companies. Increases in interest rates typically lower the present value of a REIT's future earnings stream, and may make financing property purchases and improvements more costly. Because the market price of REIT stocks may change based upon investors' collective perceptions of future &lt;/span&gt;&lt;span style="color:#000000;font-family:Arial;font-size:9.00pt;"&gt;earnings, the value of the Fund will generally decline when investors anticipate or experience rising interest rates.&lt;/span&gt;</oef:RiskTextBlock>

Investments in issuers located in the United Kingdom may subject the Fund to regulatory, political, currency, security and economic risk specific to the United Kingdom.

As a &lt;/span&gt;&lt;span style="color:#000000;font-family:Arial;font-size:9.00pt;margin-left:0%;"&gt;result, the economy of the United Kingdom may be impacted by changes to the economic health of EU member counties, the United States and China. In 2016, the United Kingdom voted via referendum to leave the EU (&lt;/span&gt;&lt;span style="color:#000000;font-family:Arial;font-size:9.00pt;font-style:italic;"&gt;&#x201c;Brexit&#x201d;&lt;/span&gt;&lt;span style="color:#000000;font-family:Arial;font-size:9.00pt;"&gt;).

The precise impact on the United Kingdom&#x2019;s economy as a result of its departure from the EU depends to a large degree on its ability to conclude favorable trade deals with the EU and other countries, including the United States, China, India and Japan. While new trade deals may boost economic growth, such growth may not be able to offset the increased costs of trade with the EU resulting from the United Kingdom&#x2019;s loss of its membership in the EU single market.

The value established for any portfolio holding at a point in time might differ from what would be produced using a different methodology or if it had been priced using market quotations. Portfolio holdings that are valued using techniques other than market quotations, including &#x201c;fair valued&#x201d; assets or securities, may be subject to greater fluctuation in their valuations from one day to the next than if market quotations were used. &lt;/span&gt;&lt;span style="font-family:Arial;font-size:9.00pt;"&gt;Fund investments that trade on non-U.S. &lt;/span&gt;&lt;span style="font-family:Arial;font-size:9.00pt;margin-left:0%;"&gt;exchanges that close prior to the close of the NYSE may be fair valued using a systematic fair valuation model.

In order to allow for foreign investment in these businesses, many Chinese companies have created VIE structures to enable indirect foreign ownership. In such an arrangement, a Chinese operating company typically establishes an offshore shell company in another jurisdiction, such as the Cayman Islands. That shell company enters into service and other contracts with the Chinese issuer or operating company to obtain economic exposure to the Chinese company, then issues shares on an exchange outside of mainland China, and U.S. investors hold stock in the non-Chinese shell company rather than directly in the Chinese issuer or operating company. This arrangement allows U.S. investors, such as the Fund, to obtain economic exposure to the Chinese issuer or operating company through contractual means rather than through formal equity ownership. Because neither the shell company nor the Fund owns actual equity interests in the Chinese operating company, they do not have the voting rights or other types of control that an equity holder would expect to benefit from. Although VIEs are a longstanding industry practice and well known to officials and regulators in China, VIEs are not formally recognized under Chinese law. Intervention by the Chinese government with respect to VIEs could significantly affect the Chinese company&#x2019;s performance and the enforceability of the VIE&#x2019;s contractual arrangements that establish the links between the Chinese company and the shell company in which the Fund invests. This could considerably impact the financial condition of the shell company in which the Fund invests by limiting its ability to consolidate the financial results of the Chinese operating company into its own financial statements, as well as make the value of the shares held by the Fund effectively worthless. Further, if Chinese officials prohibit the existence of VIEs, the market value of the Fund&#x2019;s associated holdings would likely suffer significant, and possibly permanent effects, which could negatively impact the Fund&#x2019;s net asset value and could result in substantial losses. Further, it is uncertain whether any new laws, rules or regulations relating to VIE structures will be adopted &lt;/span&gt;&lt;span style="color:#000000;font-family:Arial;font-size:9.00pt;"&gt;or, if adopted, what impact they would have on the value of the Fund&#x2019;s shares.  &lt;/span&gt;&lt;span style="color:#000000;font-family:Arial;font-size:9.00pt;margin-left:0%;"&gt;VIEs are also subject to the investment risks associated with the underlying Chinese issuer or operating company. Chinese companies are not subject to the same degree of regulatory requirements or accounting standards and oversight as companies in more developed countries. As a result, information about the Chinese securities and VIEs in which the Fund invests may be less reliable and incomplete. There also may be significant obstacles to obtaining information necessary for investigations into or litigation against Chinese companies and VIEs, and shareholders may have limited legal remedies, which could negatively impact the Fund. Additionally, U.S.-listed VIEs may be delisted if they do not meet U.S. accounting standards and auditor oversight requirements. Delisting would significantly decrease the liquidity and value of the securities, decrease the ability of the Fund to invest in such securities and may increase the cost of the Fund if required to seek alternative markets in which &lt;/span&gt;&lt;span style="color:#000000;font-family:Arial;font-size:9.00pt;"&gt;to invest in such securities.&lt;/span&gt;</oef:RiskTextBlock>

The Fund considers an emerging market company to be one &lt;/span&gt;&lt;span style="color:#000000;font-family:Arial;font-size:9.00pt;margin-left:0%;"&gt;(i) domiciled or with a principal place of business or primary securities trading market in an emerging market country, or (ii) that derives a substantial portion of its total revenues or profits from emerging market countries. The Fund considers an emerging market country to be any country whose issuers are included in the Morgan Stanley Capital International Emerging Markets Index and/or those countries considered to be developing by the World Bank, the International Finance Corporation or the United Nations. The Fund generally focuses its emerging market company investments in Brazil, Chile, China, Colombia, &lt;/span&gt;&lt;span style="color:#000000;font-family:Arial;font-size:9.00pt;margin-left:0%;"&gt;the Czech Republic, Egypt, Greece, Hungary, India, Indonesia, Malaysia, Mexico, Morocco, Nigeria, Peru, the Philippines, Poland, Qatar, Russia, South Africa, South Korea, Taiwan, Thailand, Turkey and/or the United Arab Emirates. The securities in which the Fund may invest must be listed on a U.S. or non-U.S. securities exchange. The Fund may invest in small, mid and large &lt;/span&gt;&lt;span style="color:#000000;font-family:Arial;font-size:9.00pt;"&gt;capitalization companies.  &lt;/span&gt;&lt;span style="color:#000000;font-family:Arial;font-size:9.00pt;margin-left:0%;"&gt;The Fund utilizes a dynamic currency hedging strategy through the use of forward foreign currency exchange contracts and currency spot transactions to hedge up to 100% of the Fund&#x2019;s currency exposure. As a result of this hedging strategy, the portion of the Fund&#x2019;s portfolio securities which are subject to currency hedging transactions may vary widely, from 0% to 100% of the portfolio securities. A forward contract on foreign currency is an obligation to purchase or sell a specific currency at a future date, which may be any fixed number of days agreed upon by the parties from the date of the contract, at a price set on the date of the contract. A forward foreign currency exchange contract may reduce the Fund&#x2019;s exposure to changes in the value of the currency it will deliver and increase its exposure to changes in the value of the currency it will receive for the duration of the contract. The effect on the value of the Fund is similar to selling securities denominated in one currency and purchasing securities denominated in another currency. The Fund also may enter into currency spot transactions as part of its dynamic currency hedging strategy. A currency spot transaction is an agreement between two parties to buy or sell a specific currency for delivery on a date that is typically two business days from the date of the agreement, as opposed to a date set in the future. The underlying currencies of the forward foreign currency exchange contracts and currency spot transactions included in the Fund&#x2019;s policy relating to the investment of at least 80% of its net assets (including investment &lt;/span&gt;&lt;span style="color:#000000;font-family:Arial;font-size:9.00pt;"&gt;borrowings) will be limited to Emerging Market currencies.  &lt;/span&gt;&lt;span style="color:#000000;font-family:Arial;font-size:9.00pt;margin-left:0%;"&gt;The Fund also may invest up to 20% of its net assets in equity securities of companies in developed market countries and forward foreign currency exchange contracts and currency spot transactions used to hedge the Fund&#x2019;s exposure to non-Emerging Market currencies as well as any proxy currency hedging transactions involving non-Emerging Market currencies determined to be representative of, and serve as a proxy for, Emerging Market currencies. Such developed market companies are companies that are (i) domiciled or with a principal place of business or primary securities trading market in a country that is not an emerging market country, or (ii) that derives a substantial portion of its total revenues or profits from countries that are not emerging market countries. The equity securities of developed market companies in which the Fund may invest &lt;/span&gt;&lt;span style="color:#000000;font-family:Arial;font-size:9.00pt;"&gt;include investments in common stock, depositary receipts and common and preferred shares of REITs.  &lt;/span&gt;&lt;span style="color:#000000;font-family:Arial;font-size:9.00pt;margin-left:0%;"&gt;In selecting the portfolio securities of the Fund, RiverFront Investment Group, LLC, the Fund&#x2019;s sub-advisor (&lt;/span&gt;&lt;span style="color:#000000;font-family:Arial;font-size:9.00pt;font-style:italic;"&gt;&#x201c;RIG&#x201d;&lt;/span&gt;&lt;span style="color:#000000;font-family:Arial;font-size:9.00pt;"&gt; or the &lt;/span&gt;&lt;span style="color:#000000;font-family:Arial;font-size:9.00pt;font-style:italic;margin-left:0%;"&gt;&#x201c;Sub-Advisor&#x201d;&lt;/span&gt;&lt;span style="color:#000000;font-family:Arial;font-size:9.00pt;"&gt;), assembles a portfolio of eligible countries and/or securities based on several core attributes, including, but &lt;/span&gt;&lt;span style="color:#000000;font-family:Arial;font-size:9.00pt;margin-left:0%;"&gt;not limited to, value, quality and momentum. The Sub-Advisor considers multiple factors within each core attribute, such as the price-to-book value of a security when determining value and a company&#x2019;s cash as a percentage of the company&#x2019;s market capitalization when determining quality. The Sub-Advisor then assigns each qualifying security a score based on its core attributes and selects the individual securities with the highest scores for investment. In doing so, the Sub-Advisor utilizes its proprietary optimization process to maximize the percentage of high-scoring securities included in the portfolio in accordance with country, sector and risk factor (&lt;/span&gt;&lt;span style="color:#000000;font-family:Arial;font-size:9.00pt;font-style:italic;"&gt;e.g.&lt;/span&gt;&lt;span style="color:#000000;font-family:Arial;font-size:9.00pt;"&gt;, beta, quality, volatility) limitations, subject to the Sub-Advisor's &lt;/span&gt;&lt;span style="color:#000000;font-family:Arial;font-size:9.00pt;margin-left:0%;"&gt;fundamental active overlay. The Sub-Advisor also considers the market capitalization of the companies in which the Fund may invest, and the trading volume of a company&#x2019;s shares in the secondary market. The strategy is largely quantitative and rules-based, but also includes multiple parameters over which the Sub-Advisor may exercise discretion (including, but not limited to, the number of holdings and the weightings of particular holdings) in connection with its active management of &lt;/span&gt;&lt;span style="color:#000000;font-family:Arial;font-size:9.00pt;"&gt;the Fund.  &lt;/span&gt;&lt;span style="color:#000000;font-family:Arial;font-size:9.00pt;margin-left:0%;"&gt;In managing the Fund&#x2019;s currency exposure, the Sub-Advisor deploys a dynamic currency hedging strategy based on a proprietary hedging methodology that considers a combination of quantitative measures, such as interest rate differentials, central bank balance sheet expansion/contraction and price momentum, and qualitative measures, such as formal and informal guidance &lt;/span&gt;&lt;span style="color:#000000;font-family:Arial;font-size:9.00pt;"&gt;from central bankers.  &lt;/span&gt;&lt;span style="color:#000000;font-family:Arial;font-size:9.00pt;margin-left:0%;"&gt;To the extent permitted under applicable law, percentage limitations described in this prospectus are generally as of the time of investment by the Fund and may be exceeded on a going-forward basis as a result of market fluctuations affecting the &lt;/span&gt;&lt;span style="color:#000000;font-family:Arial;font-size:9.00pt;"&gt;Fund&#x2019;s portfolio securities.  &lt;/span&gt;&lt;span style="font-family:Arial;font-size:9.00pt;margin-left:0%;"&gt;As of January 30, 2026, the Fund had significant investments in financial companies, information technology companies, Taiwanese issuers and Asian issuers, although this may change from time to time.&lt;/span&gt;&lt;span style="font-family:Arial;font-size:9.00pt;"&gt; Over time, the Fund may have significant &lt;/span&gt;&lt;span style="font-family:Arial;font-size:9.00pt;margin-left:0%;"&gt;investments in a jurisdiction, investment sector or industry or group of industries that it may not have had as of January 30, 2026.

Many &lt;/span&gt;&lt;span style="color:#000000;font-family:Arial;font-size:9.00pt;margin-left:0%;"&gt;Asian economies have experienced rapid growth and industrialization, and there is no assurance that this growth rate will be maintained. Some Asian economies are highly dependent on trade, and economic conditions in other countries within and outside Asia can impact these economies. Certain of these economies may be adversely affected by trade or policy disputes with its major trade partners. There is also a high concentration of market capitalization and trading volume in a small number of issuers representing a limited number of industries, as well as a high concentration of investors and financial intermediaries. Certain Asian countries have experienced and may in the future experience expropriation and nationalization of assets, confiscatory taxation, currency manipulation, political instability, armed conflict and social instability as a result of religious, ethnic, socio-economic and/or political unrest. In particular, escalated tensions involving North Korea and any outbreak of hostilities involving North Korea could have a severe adverse effect on Asian economies. Governments of certain Asian countries have exercised, and continue to exercise, substantial influence over many aspects of the private sector. In certain cases, the government owns or controls many companies, including the largest in the country. Accordingly, government actions could have a significant effect on the issuers of the Fund&#x2019;s securities or on economic conditions generally. Recent developments in relations between the U.S. and China have heightened concerns of increased tariffs and restrictions on trade between the two countries. An increase in tariffs or trade restrictions, or even the threat of such developments, could lead to a significant reduction in international trade, which could have a negative impact on the economy of Asian countries and a commensurately &lt;/span&gt;&lt;span style="color:#000000;font-family:Arial;font-size:9.00pt;"&gt;negative impact on the Fund.&lt;/span&gt;</oef:RiskTextBlock>

The Fund&#x2019;s net asset value could decline if a currency to which the Fund has exposure depreciates against the U.S. dollar or if there are delays or limits on repatriation of such currency. Currency exchange rates can be very volatile and can change quickly and unpredictably. As a result, the value of an investment &lt;/span&gt;&lt;span style="color:#000000;font-family:Arial;font-size:9.00pt;"&gt;in the Fund may change quickly and without warning.&lt;/span&gt;</oef:RiskTextBlock>

As a means to fight inflation, &lt;/span&gt;&lt;span style="font-family:Arial;font-size:9.00pt;"&gt;the Federal Reserve and &lt;/span&gt;&lt;span style="font-family:Arial;font-size:9.00pt;margin-left:0%;"&gt;certain foreign central banks have raised interest rates; however, the Federal Reserve has &lt;/span&gt;&lt;span style="font-family:Arial;font-size:9.00pt;"&gt;begun to lower interest rates and &lt;/span&gt;&lt;span style="font-family:Arial;font-size:9.00pt;margin-left:0%;"&gt;may continue to do so. U.S. regulators have proposed several changes to market and issuer regulations which would directly impact the Fund, and any regulatory changes could adversely impact the Fund&#x2019;s ability to achieve its investment strategies or make certain investments. &lt;/span&gt;&lt;span style="font-family:Arial;font-size:9.00pt;"&gt;Potential future bank failures could result in disruption to the broader banking industry or markets &lt;/span&gt;&lt;span style="font-family:Arial;font-size:9.00pt;margin-left:0%;"&gt;generally and reduce confidence in financial institutions and the economy as a whole, which may also heighten market volatility and reduce liquidity. Additionally, challenges in commercial real estate markets, including &lt;/span&gt;&lt;span style="font-family:Arial;font-size:9.00pt;"&gt;high interest rates, declining valuations &lt;/span&gt;&lt;span style="font-family:Arial;font-size:9.00pt;margin-left:0%;"&gt;and &lt;/span&gt;&lt;span style="font-family:Arial;font-size:9.00pt;"&gt;elevated vacancies, could have a broader impact on financial markets. The ongoing adversarial political climate in the &lt;/span&gt;&lt;span style="font-family:Arial;font-size:9.00pt;margin-left:0%;"&gt;United States, as well as political and diplomatic events both domestic and abroad, have and may continue to have an adverse impact the U.S. regulatory landscape, markets and investor behavior, which could have a negative impact on the Fund&#x2019;s investments and operations. The change in administration resulting from the 2024 United States national elections could result in significant impacts to international trade relations, tax and immigration policies, and other aspects of the national and international political and financial landscape, which could affect, among other things, inflation and the securities markets generally. Other unexpected political, regulatory and diplomatic events within the U.S. and abroad may affect investor and consumer confidence and may adversely impact financial markets and the broader economy. For example, ongoing armed conflicts between Russia and Ukraine in Europe and among Israel, Iran, Hamas and other militant groups in the Middle East, have caused and could continue to cause significant market disruptions and volatility within the markets in Russia, Europe, the Middle East and the United States. The hostilities and sanctions resulting from those hostilities have and could continue to have a significant impact on certain Fund investments as well as Fund performance and liquidity. The economies of the United States and its trading partners, as well as the financial markets generally, may be adversely impacted by trade disputes&lt;/span&gt;&lt;span style="font-family:Arial;font-size:9.00pt;"&gt;,  &lt;/span&gt;&lt;span style="font-family:Arial;font-size:9.00pt;margin-left:0%;"&gt;including the imposition of tariffs,&lt;/span&gt;&lt;span style="font-family:Arial;font-size:9.00pt;"&gt; and other matters. For example, the United States has imposed trade barriers and restrictions &lt;/span&gt;&lt;span style="font-family:Arial;font-size:9.00pt;margin-left:0%;"&gt;on China. In addition, the Chinese government is engaged in a longstanding dispute with Taiwan, continually threatening an invasion. If the political climate between the United States and China does not improve or continues to deteriorate, if China were to attempt invading Taiwan, or if other geopolitical conflicts develop or worsen, economies, markets and individual securities may be adversely affected, and the value of the Fund&#x2019;s assets may go down. A public health crisis and the ensuing policies enacted by governments and central banks may cause significant volatility and uncertainty in global financial markets, negatively impacting global growth prospects. As the COVID-19 global pandemic illustrated, such events may affect certain geographic regions, countries, sectors and industries more significantly than others. Advancements in technology may also adversely impact markets and the overall performance of the Fund. For instance, the economy may be significantly impacted by the advanced development and increased regulation of artificial intelligence. Additionally, cyber security breaches of both government and non-government entities could have negative impacts on infrastructure and the ability of such entities, including the Fund, to operate properly. These events, and any other future events, may adversely affect the prices and liquidity &lt;/span&gt;&lt;span style="font-family:Arial;font-size:9.00pt;"&gt;of the Fund&#x2019;s portfolio investments and could result in disruptions in the trading markets.&lt;/span&gt;</oef:RiskTextBlock>

A breach in cyber security refers to both intentional and unintentional events that may cause the Fund to lose proprietary information, suffer data corruption or lose operational capacity&lt;/span&gt;&lt;span style="font-family:Arial;font-size:9.00pt;"&gt;, any of which could result in a material adverse &lt;/span&gt;&lt;span style="font-family:Arial;font-size:9.00pt;margin-left:0%;"&gt;effect on the Fund or its shareholders&lt;/span&gt;&lt;span style="font-family:Arial;font-size:9.00pt;"&gt;.

Cyber security breaches may involve unauthorized access to the Fund&#x2019;s digital information systems through &#x201c;hacking&#x201d; or malicious software coding but may also result from outside attacks such as denial-of-service attacks through efforts to make network services unavailable to intended users. &lt;/span&gt;&lt;span style="font-family:Arial;font-size:9.00pt;"&gt;Emerging threats like ransomware or zero-day exploits could also cause disruptions to Fund operations. In addition, &lt;/span&gt;&lt;span style="font-family:Arial;font-size:9.00pt;margin-left:0%;"&gt;cyber security breaches of the issuers of securities in which the Fund invests or the Fund&#x2019;s third-party service providers, such as its administrator, transfer agent, custodian, or sub-advisor, as applicable, &lt;/span&gt;&lt;span style="font-family:Arial;font-size:9.00pt;"&gt;among many other third-party service providers,  &lt;/span&gt;&lt;span style="font-family:Arial;font-size:9.00pt;margin-left:0%;"&gt;can also subject the Fund to many of the same risks associated with direct cyber security breaches. &lt;/span&gt;&lt;span style="font-family:Arial;font-size:9.00pt;"&gt;Further, errors, misconduct, &lt;/span&gt;&lt;span style="font-family:Arial;font-size:9.00pt;margin-left:0%;"&gt;or compromise of accounts of employees of the Fund or its third-party service providers can also create material cybersecurity risks.&lt;/span&gt;&lt;span style="font-family:Arial;font-size:9.00pt;"&gt; Although the Fund has established risk management systems designed to reduce the risks associated with cyber security, &lt;/span&gt;&lt;span style="font-family:Arial;font-size:9.00pt;margin-left:0%;"&gt;there is no guarantee that such efforts will succeed, especially because the Fund does not directly control the cyber security systems of issuers or third-party service providers.&lt;/span&gt;&lt;span style="font-family:Arial;font-size:9.00pt;"&gt; Cyber security incidents may also trigger Fund obligations under data privacy &lt;/span&gt;&lt;span style="font-family:Arial;font-size:9.00pt;margin-left:0%;"&gt;laws, potentially increasing notification and compliance burdens. Cyber security incidents affecting issuers in whose securities the Fund invests may also have a negative impact on the value of the securities of such issuers, and in turn, the value of the &lt;/span&gt;&lt;span style="font-family:Arial;font-size:9.00pt;"&gt;Fund.&lt;/span&gt;</oef:RiskTextBlock>

These risks include or may include: (i) the risk that the value of the underlying assets may go up or down; (ii) the risk that the counterparty to a derivative transaction may not fulfill its contractual obligations; (iii) the risk of mispricing or improper valuation of a derivative; (iv) the risk that changes in the value of the derivative may not correlate perfectly with the underlying asset; (v) the risk that a derivative instrument cannot be sold, closed out or replaced quickly at or very close to its fundamental value; (vi) the risk of loss caused by the unenforceability of a party&#x2019;s obligations under the derivative; and (vii) the risk that a disruption in the financial markets will cause difficulties for all market participants. Derivative prices are highly volatile and may fluctuate substantially during a short period of time. Such prices are influenced by numerous factors that affect the markets, including, but not limited to: changing supply and demand relationships; government programs and policies; national and international political and economic events, changes in interest rates, inflation and deflation and changes in supply and demand relationships. Trading derivative instruments involves risks different from, or possibly greater than, the risks associated with investing directly in securities. Derivative contracts ordinarily have leverage inherent in their terms. The low margin deposits normally required in trading derivatives, including futures contracts, permit a high degree of leverage. Accordingly, a relatively small price movement may result in an immediate and substantial loss. The use of leverage may also cause the Fund to liquidate portfolio positions when it would not be advantageous to do so. The use of leveraged derivatives can magnify potential for gain or loss and, therefore, amplify the &lt;/span&gt;&lt;span style="color:#000000;font-family:Arial;font-size:9.00pt;"&gt;effects of market volatility on share price.&lt;/span&gt;</oef:RiskTextBlock>

As such, contracts to sell foreign currency will generally be expected to limit any potential gain that might be realized by the Fund if the value of the hedged currency increases. In addition, the use of currency hedging will not necessarily eliminate exposure to all currency fluctuations. Hedging against a decline in the value of a currency does not eliminate fluctuations in the value of a portfolio security traded in that currency or prevent a loss if the value of the security declines. Moreover, it may not be possible for the Fund to hedge against a devaluation that is so generally anticipated that the Fund is not able to contract &lt;/span&gt;&lt;span style="color:#000000;font-family:Arial;font-size:9.00pt;"&gt;to sell the currency at a price above the devaluation level it anticipates.&lt;/span&gt;</oef:RiskTextBlock>

Investments in emerging markets securities are generally considered speculative in nature and are subject to the following heightened risks: smaller market capitalization of securities markets which may suffer periods of relative illiquidity; significant price volatility; restrictions on foreign investment; possible repatriation of investment income and capital; rapid inflation; and currency convertibility issues. Emerging market countries also often have less uniformity in accounting, auditing and reporting requirements, unsettled securities laws, unreliable securities valuation and greater risk associated with custody of securities. Financial and other reporting by companies and government entities also may be less reliable in emerging market countries. Shareholder claims that are available in the U.S., as well as regulatory oversight and authority that is common in the U.S., including for claims based on fraud, may be difficult or impossible for shareholders of securities in emerging market countries or for U.S. authorities to pursue. For funds that track an index or are managed based upon a benchmark, the index may not weight the securities in emerging market countries on the basis of investor protection limitations, financial reporting quality or available oversight mechanisms. Furthermore, investors may be required to register the proceeds of sales and future economic or political crises could lead to price controls, forced mergers, expropriation or confiscatory taxation, seizure, &lt;/span&gt;&lt;span style="color:#000000;font-family:Arial;font-size:9.00pt;"&gt;nationalization or creation of government monopolies.&lt;/span&gt;</oef:RiskTextBlock>

The market for forward contracts is substantially unregulated and can experience lengthy periods of illiquidity, unusually high trading volume and other negative impacts, such as political intervention, which may result in volatility or disruptions in such markets. A relatively small price movement in a forward contract may result in substantial losses to the Fund, exceeding the amount of the margin paid. Forward contracts can increase the Fund&#x2019;s risk exposure to underlying references and their attendant risks, such as credit risk, currency risk, market risk, and interest rate risk, while also exposing the Fund to counterparty risk, liquidity risk and &lt;/span&gt;&lt;span style="color:#000000;font-family:Arial;font-size:9.00pt;"&gt;valuation risk, among others.&lt;/span&gt;</oef:RiskTextBlock>

There are no limitations on daily price moves in such forward contracts, and banks and dealers are not required to continue to make markets in such contracts. There have been periods during which certain banks or dealers have refused to quote prices for such forward contracts or have quoted prices with an unusually wide spread between the price at which the bank or dealer is prepared to buy and that at which it is prepared to sell. Governmental imposition of credit controls might limit any such forward contract trading. Forward foreign currency exchange contracts involve certain risks, including the risk of failure of the counterparty to perform its obligations under the contract and the risk that the use of forward contracts may not serve as a complete hedge because of an imperfect correlation between movements in the prices of the contracts and the prices of the currencies hedged. Forward foreign currency exchange contracts may limit any potential gain that might result should the value of the underlying currencies increase. In addition, because forward currency exchange contracts are privately negotiated transactions, there can be no assurance that the Fund &lt;/span&gt;&lt;span style="color:#000000;font-family:Arial;font-size:9.00pt;"&gt;will have flexibility to roll-over a forward foreign currency exchange contract upon its expiration if it desires to do so.&lt;/span&gt;</oef:RiskTextBlock>

Information technology companies also heavily rely on intellectual property rights &lt;/span&gt;&lt;span style="color:#000000;font-family:Arial;font-size:9.00pt;"&gt;and may be adversely affected by the loss or impairment of those rights.&lt;/span&gt;</oef:RiskTextBlock>

The Fund&#x2019;s investment advisor cannot predict whether shares will trade below, at or above their net asset value because the shares trade on the Exchange at market prices and not at net asset value. Price differences may be due, in large part, to the fact that supply and demand forces at work in the secondary trading market for shares will be closely related, but not identical, to the same forces influencing the prices of the holdings of the Fund trading individually or in the aggregate at any point in time. However, given that shares can only be purchased and redeemed in Creation Units, and only to and from broker-dealers and large institutional investors that have entered into participation agreements (unlike shares of closed-end funds, which frequently trade at appreciable discounts from, and sometimes at premiums to, their net asset value), the Fund&#x2019;s investment advisor believes that large discounts or premiums to the net asset value of shares should not be sustained. During stressed market conditions, the market for the Fund&#x2019;s shares may become less liquid in response to deteriorating liquidity in the market for the Fund&#x2019;s underlying portfolio holdings, which could in turn lead to differences between the market price of the Fund&#x2019;s shares and their net asset &lt;/span&gt;&lt;span style="color:#000000;font-family:Arial;font-size:9.00pt;"&gt;value and the bid/ask spread on the Fund&#x2019;s shares may widen.&lt;/span&gt;</oef:RiskTextBlock>

As a result, investments in REITs are subject to the risks associated with investing in real estate, which may include, but are not limited to: fluctuations in the value of underlying properties; defaults by borrowers or tenants; market saturation; changes in general and local operating expenses; and other economic, political or regulatory occurrences affecting companies in the real estate sector. REITs are also subject to the risk that the real estate market may experience an economic downturn generally, which may have a material effect on the real estate in which the REITs invest and their underlying portfolio securities. REITs may have also a relatively small market capitalization which may result in their shares experiencing less market liquidity and greater price volatility than larger companies. Increases in interest rates typically lower the present value of a REIT's future earnings stream, and may make financing property purchases and improvements more costly. Because the market price of REIT stocks may change based upon investors' collective perceptions of future &lt;/span&gt;&lt;span style="color:#000000;font-family:Arial;font-size:9.00pt;"&gt;earnings, the value of the Fund will generally decline when investors anticipate or experience rising interest rates.&lt;/span&gt;</oef:RiskTextBlock>

This may occur because the asset or security does not trade on a centralized exchange, or in times of market turmoil or reduced liquidity. There are multiple methods that can be used to value a portfolio holding when market quotations are not readily available. The value established for any portfolio holding at a point in time might differ from what would be produced using a different methodology or if it had been priced using market quotations. Portfolio holdings that are valued using techniques other than market quotations, including &#x201c;fair valued&#x201d; assets or securities, may be subject to greater fluctuation in their valuations from one day to the next than if market quotations were used. &lt;/span&gt;&lt;span style="font-family:Arial;font-size:9.00pt;"&gt;Fund investments that trade on non-U.S. &lt;/span&gt;&lt;span style="font-family:Arial;font-size:9.00pt;margin-left:0%;"&gt;exchanges that close prior to the close of the NYSE may be fair valued using a systematic fair valuation model. If these foreign investments meet certain criteria in relation to the valuation model, their valuation is systematically adjusted to reflect the impact of movement in the U.S. market after the close of certain foreign markets.&lt;/span&gt;&lt;span style="font-family:Arial;font-size:9.00pt;"&gt; In addition, there is no assurance that the &lt;/span&gt;&lt;span style="font-family:Arial;font-size:9.00pt;margin-left:0%;"&gt;Fund could sell or close out a portfolio position for the value established for it at any time, and it is possible that the Fund would incur a loss because a portfolio position is sold or closed out at a discount to the valuation established by the Fund at that time. The Fund&#x2019;s ability to value investments may be impacted by technological issues or errors by pricing services or &lt;/span&gt;&lt;span style="font-family:Arial;font-size:9.00pt;"&gt;other third-party service providers.&lt;/span&gt;</oef:RiskTextBlock>

In order to allow for foreign investment in these businesses, many Chinese companies have created VIE structures to enable indirect foreign ownership. In such an arrangement, a Chinese operating company typically establishes an offshore shell company in another jurisdiction, such as the Cayman Islands. That shell company enters into service and other contracts with the Chinese issuer or operating company to obtain economic exposure to the Chinese company, then issues shares on an exchange outside of mainland China, and U.S. investors hold stock in the non-Chinese shell company rather than directly in the Chinese issuer or operating company. This arrangement allows U.S. investors, such as the Fund, to obtain economic exposure to the Chinese issuer or operating company through contractual means rather than through formal equity ownership. Because neither the shell company nor the Fund owns actual equity interests in the Chinese operating company, they do not have the voting rights or other types of control that an equity holder would expect to benefit from. Although VIEs are a longstanding industry practice and well known to officials and regulators in China, VIEs are not formally recognized under Chinese law. Intervention by the Chinese government with respect to VIEs could significantly affect the Chinese company&#x2019;s performance and the enforceability of the VIE&#x2019;s contractual arrangements that establish the links between the Chinese company and the shell company in which the Fund invests. This could considerably impact the financial condition of the shell company in which the Fund invests by limiting its ability to consolidate the financial results of the Chinese operating company into its own financial statements, as well as make the value of the shares held by the Fund effectively worthless. Further, if Chinese officials prohibit the existence of VIEs, the market value of the Fund&#x2019;s associated holdings would likely suffer significant, and possibly permanent effects, which could negatively impact the Fund&#x2019;s net asset value and could result in substantial losses. Further, it is uncertain whether any new laws, rules or regulations relating to VIE structures will be adopted &lt;/span&gt;&lt;span style="color:#000000;font-family:Arial;font-size:9.00pt;"&gt;or, if adopted, what impact they would have on the value of the Fund&#x2019;s shares.  &lt;/span&gt;&lt;span style="color:#000000;font-family:Arial;font-size:9.00pt;margin-left:0%;"&gt;VIEs are also subject to the investment risks associated with the underlying Chinese issuer or operating company. Chinese companies are not subject to the same degree of regulatory requirements or accounting standards and oversight as companies in more developed countries. As a result, information about the Chinese securities and VIEs in which the Fund invests may be less reliable and incomplete. There also may be significant obstacles to obtaining information necessary for investigations into or litigation against Chinese companies and VIEs, and shareholders may have limited legal remedies, which could negatively impact the Fund. Additionally, U.S.-listed VIEs may be delisted if they do not meet U.S. accounting standards and auditor oversight requirements. Delisting would significantly decrease the liquidity and value of the securities, decrease the ability of the Fund to invest in such securities and may increase the cost of the Fund if required to seek alternative markets in which &lt;/span&gt;&lt;span style="color:#000000;font-family:Arial;font-size:9.00pt;"&gt;to invest in such securities.&lt;/span&gt;</oef:RiskTextBlock>
