If, subsequent to purchase by the Fund, a Municipal Security held by the Fund becomes a Distressed Municipal Security, the Fund may continue to hold the Distressed Municipal Security and it will not cause the Fund to violate the 10% investment limitation; however, the Distressed Municipal Security will be taken into account for purposes of determining whether purchases of additional Municipal Securities will cause the Fund to violate such limitation. &lt;/span&gt;&lt;span style="color:#000000;font-family:Arial;font-size:9.00pt;"&gt;The Fund may also invest in derivatives instruments (including futures contracts).&lt;/span&gt;</rr:StrategyNarrativeTextBlock>

As a means to fight inflation, which remains at elevated levels, the Federal Reserve and certain foreign central banks have raised interest rates&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;line-height:10.80pt;"&gt;  &lt;/span&gt;&lt;span style="font-family:Arial;font-size:9.00pt;"&gt;however, the Federal Reserve has recently lowered interest rates and may continue to do so. U.S. regulators have proposed several changes to market and issuer &lt;/span&gt;&lt;span style="font-family:Arial;font-size:9.00pt;margin-left:0%;"&gt;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. Recent and potential future bank failures could result in disruption to the broader banking industry or markets generally and reduce confidence in financial institutions and the economy as a whole, which may also heighten market volatility and reduce liquidity. &lt;/span&gt;&lt;span style="font-family:Arial;font-size:9.00pt;"&gt;Additionally, challenges in commercial real estate &lt;/span&gt;&lt;span style="font-family:Arial;font-size:9.00pt;margin-left:0%;"&gt;markets, including rising interest rates, declining valuations and increasing vacancies, could have a broader impact on financial markets.&lt;/span&gt;&lt;span style="font-family:Arial;font-size:9.00pt;"&gt; The ongoing adversarial political climate in the United States, as well as political and diplomatic events both domestic &lt;/span&gt;&lt;span style="font-family:Arial;font-size:9.00pt;margin-left:0%;"&gt;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. &lt;/span&gt;&lt;span style="font-family:Arial;font-size:9.00pt;"&gt;The change in administration resulting from &lt;/span&gt;&lt;span style="font-family:Arial;font-size:9.00pt;margin-left:0%;"&gt;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.&lt;/span&gt;&lt;span style="font-family:Arial;font-size:9.00pt;"&gt; Other unexpected political, regulatory and diplomatic events within the &lt;/span&gt;&lt;span style="font-family:Arial;font-size:9.00pt;margin-left:0%;"&gt;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, &lt;/span&gt;&lt;span style="font-family:Arial;font-size:9.00pt;"&gt;Iran, Hamas and &lt;/span&gt;&lt;span style="font-family:Arial;font-size:9.00pt;margin-left:0%;"&gt;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 and other matters. For example, the United States has imposed trade barriers and restrictions 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. &lt;/span&gt;&lt;span style="font-family:Arial;font-size:9.00pt;"&gt;A public health crisis and the ensuing &lt;/span&gt;&lt;span style="font-family:Arial;font-size:9.00pt;margin-left:0%;"&gt;policies enacted by governments and central banks &lt;/span&gt;&lt;span style="font-family:Arial;font-size:9.00pt;"&gt;may cause significant volatility and uncertainty in global financial markets, &lt;/span&gt;&lt;span style="font-family:Arial;font-size:9.00pt;margin-left:0%;"&gt;negatively impacting global growth prospects. &lt;/span&gt;&lt;span style="font-family:Arial;font-size:9.00pt;"&gt;As the COVID-19 global pandemic illustrated, such events may affect certain &lt;/span&gt;&lt;span style="font-family:Arial;font-size:9.00pt;margin-left:0%;"&gt;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. &lt;/span&gt;&lt;span style="font-family:Arial;font-size:9.00pt;"&gt;Additionally, cyber security breaches of both &lt;/span&gt;&lt;span style="font-family:Arial;font-size:9.00pt;margin-left:0%;"&gt;government and non-government entities could have negative impacts on infrastructure and the ability of such entities, including the Fund, to operate properly.&lt;/span&gt;&lt;span style="font-family:Arial;font-size:9.00pt;"&gt; These events, and any other future events, may adversely affect the prices and liquidity of the Fund&#x2019;s portfolio investments and could result in disruptions in the trading markets.&lt;/span&gt;</rr:RiskTextBlock>

A breach in cyber &lt;/span&gt;&lt;span style="color:#000000;font-family:Arial;font-size:9.00pt;margin-left:0%;"&gt;security refers to both intentional and unintentional events that may cause the Fund to lose proprietary information, suffer data corruption or lose operational capacity. Such events could cause the Fund to incur regulatory penalties, reputational damage, 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. In addition, 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, can also subject the Fund to many of the same risks associated with direct cyber security breaches. Although the Fund has established risk management systems designed to reduce the risks associated with cyber security, 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 &lt;/span&gt;&lt;span style="color:#000000;font-family:Arial;font-size:9.00pt;"&gt;providers.&lt;/span&gt;</rr:RiskTextBlock>

Credit risk refers to &lt;/span&gt;&lt;span style="color:#000000;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 &lt;/span&gt;&lt;span style="color:#000000;font-family:Arial;font-size:9.00pt;"&gt;more difficult to value than common stock.&lt;/span&gt;</rr:RiskTextBlock>

Derivative prices are highly volatile and may fluctuate substantially during a short period of time. &lt;/span&gt;&lt;span style="font-family:Arial;font-size:9.00pt;margin-left:0%;"&gt;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="font-family:Arial;font-size:9.00pt;"&gt;effects of market volatility on share price.&lt;/span&gt;</rr: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;</rr:RiskTextBlock>

To the extent that investments in the industrial development sector represent a significant portion of the Fund&#x2019;s portfolio, the Fund will be sensitive to changes in, and its performance may depend to a greater extent on, the overall condition of the industrial development sector. 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. Generally, the value and credit quality of these bonds are &lt;/span&gt;&lt;span style="color:#000000;font-family:Arial;font-size:9.00pt;"&gt;sensitive to the risks related to an economic slowdown.&lt;/span&gt;</rr: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;</rr:RiskTextBlock>

Decisions by market makers or authorized participants to reduce their 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="color:#000000;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;</rr:RiskTextBlock>

Shares of the Fund could decline in value or underperform other investments. In addition, local, regional or global events such as war, acts of terrorism, market manipulation, government defaults, government shutdowns, regulatory actions, political changes, diplomatic developments, the imposition of sanctions and other similar measures, spread of infectious diseases or other public health issues, recessions, natural disasters, or other events could have a significant negative impact on the Fund and its investments. Any of such circumstances could have a materially negative impact on the value of the Fund&#x2019;s shares, the liquidity of an investment, and may result in increased market volatility. During any such events, the Fund&#x2019;s shares may trade at increased premiums or discounts to their net asset value, the bid/ask spread on the Fund&#x2019;s shares may widen and the returns on investment may &lt;/span&gt;&lt;span style="color:#000000;font-family:Arial;font-size:9.00pt;"&gt;fluctuate.&lt;/span&gt;</rr: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 full impact of the COVID-19 pandemic on state and political subdivisions&#x2019; ability to make payments on debt obligations is impossible to predict, but could negatively impact &lt;/span&gt;&lt;span style="color:#000000;font-family:Arial;font-size:9.00pt;margin-left:0%;"&gt;the value of bonds, the ability of state and political subdivisions to make payments when due and the performance of the Fund.

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;</rr:RiskTextBlock>

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 &lt;/span&gt;&lt;span style="font-family:Arial;font-size:9.00pt;"&gt;Fund's&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;shares. Authorized Participants who purchase or redeem Fund shares on days &lt;/span&gt;&lt;span style="font-family:Arial;font-size:9.00pt;margin-left:0%;"&gt;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="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;</rr:RiskTextBlock>

The &lt;/span&gt;&lt;span style="color:#000000;font-family:Arial;font-size:9.00pt;margin-left:0%;"&gt;goal of this strategy is to capture upside price movements in rising markets and reduce downside risk when markets decline. To implement this strategy, the Sub-Advisor employs volatility forecasting models to forecast future expected volatility. 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 &lt;/span&gt;&lt;span style="color:#000000;font-family:Arial;font-size:9.00pt;"&gt;its active management of the Fund.  &lt;/span&gt;&lt;span style="color:#000000;font-family:Arial;font-size:9.00pt;margin-left:0%;"&gt;To begin, the Sub-Advisor gathers pricing and generates return data for the starting universe, which is comprised of common stocks of large cap domestic companies listed and traded on U.S. national securities exchanges. The Sub-Advisor then conducts volatility forecasts for securities comprising the starting universe and ranks them from low to high based on their volatility forecasts. The Sub-Advisor targets 50-200 securities for inclusion in the portfolio based on future expected volatility. Once &lt;/span&gt;&lt;span style="color:#000000;font-family:Arial;font-size:9.00pt;margin-left:0%;"&gt;the final portfolio is selected, the Sub-Advisor gives larger weights to securities with lower future expected volatility and has the ability to adjust how aggressive the weighting scheme is depending on market conditions. The Sub-Advisor periodically &lt;/span&gt;&lt;span style="color:#000000;font-family:Arial;font-size:9.00pt;"&gt;rebalances and reallocates the portfolio using this methodology, which may result in higher levels of portfolio turnover.  &lt;/span&gt;&lt;span style="font-family:Arial;font-size:9.00pt;margin-left:0%;"&gt;As of October 31, 2024, the Fund had significant investments in information technology companies, although this may change from time to time. To the extent the Fund invests a significant portion of its assets in a given jurisdiction or investment sector, &lt;/span&gt;&lt;span style="font-family:Arial;font-size:9.00pt;"&gt;the Fund may be exposed to the risks associated with that jurisdiction or investment sector.&lt;/span&gt;</rr:StrategyNarrativeTextBlock>

As a means to fight inflation, which remains at elevated levels, the Federal Reserve and certain foreign central banks have raised interest rates&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;line-height:10.80pt;"&gt;  &lt;/span&gt;&lt;span style="font-family:Arial;font-size:9.00pt;"&gt;however, the Federal Reserve has recently lowered interest rates and may continue to do so. U.S. regulators have proposed several changes to market and issuer &lt;/span&gt;&lt;span style="font-family:Arial;font-size:9.00pt;margin-left:0%;"&gt;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. Recent and potential future bank failures could result in disruption to the broader banking industry or markets generally and reduce confidence in financial institutions and the economy as a whole, which may also heighten market volatility and reduce liquidity. &lt;/span&gt;&lt;span style="font-family:Arial;font-size:9.00pt;"&gt;Additionally, challenges in commercial real estate &lt;/span&gt;&lt;span style="font-family:Arial;font-size:9.00pt;margin-left:0%;"&gt;markets, including rising interest rates, declining valuations and increasing vacancies, could have a broader impact on financial markets.&lt;/span&gt;&lt;span style="font-family:Arial;font-size:9.00pt;"&gt; The ongoing adversarial political climate in the United States, as well as political and diplomatic events both domestic &lt;/span&gt;&lt;span style="font-family:Arial;font-size:9.00pt;margin-left:0%;"&gt;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. &lt;/span&gt;&lt;span style="font-family:Arial;font-size:9.00pt;"&gt;The change in administration resulting from &lt;/span&gt;&lt;span style="font-family:Arial;font-size:9.00pt;margin-left:0%;"&gt;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.&lt;/span&gt;&lt;span style="font-family:Arial;font-size:9.00pt;"&gt; Other unexpected political, regulatory and diplomatic events within the &lt;/span&gt;&lt;span style="font-family:Arial;font-size:9.00pt;margin-left:0%;"&gt;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, &lt;/span&gt;&lt;span style="font-family:Arial;font-size:9.00pt;"&gt;Iran, Hamas and &lt;/span&gt;&lt;span style="font-family:Arial;font-size:9.00pt;margin-left:0%;"&gt;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 and other matters. For example, the United States has imposed trade barriers and restrictions 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. &lt;/span&gt;&lt;span style="font-family:Arial;font-size:9.00pt;"&gt;A public health crisis and the ensuing &lt;/span&gt;&lt;span style="font-family:Arial;font-size:9.00pt;margin-left:0%;"&gt;policies enacted by governments and central banks &lt;/span&gt;&lt;span style="font-family:Arial;font-size:9.00pt;"&gt;may cause significant volatility and uncertainty in global financial markets, &lt;/span&gt;&lt;span style="font-family:Arial;font-size:9.00pt;margin-left:0%;"&gt;negatively impacting global growth prospects. &lt;/span&gt;&lt;span style="font-family:Arial;font-size:9.00pt;"&gt;As the COVID-19 global pandemic illustrated, such events may affect certain &lt;/span&gt;&lt;span style="font-family:Arial;font-size:9.00pt;margin-left:0%;"&gt;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. &lt;/span&gt;&lt;span style="font-family:Arial;font-size:9.00pt;"&gt;Additionally, cyber security breaches of both &lt;/span&gt;&lt;span style="font-family:Arial;font-size:9.00pt;margin-left:0%;"&gt;government and non-government entities could have negative impacts on infrastructure and the ability of such entities, including the Fund, to operate properly.&lt;/span&gt;&lt;span style="font-family:Arial;font-size:9.00pt;"&gt; These events, and any other future events, may adversely affect the prices and liquidity of the Fund&#x2019;s portfolio investments and could result in disruptions in the trading markets.&lt;/span&gt;</rr:RiskTextBlock>

A breach in cyber &lt;/span&gt;&lt;span style="color:#000000;font-family:Arial;font-size:9.00pt;margin-left:0%;"&gt;security refers to both intentional and unintentional events that may cause the Fund to lose proprietary information, suffer data corruption or lose operational capacity. Such events could cause the Fund to incur regulatory penalties, reputational damage, 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. In addition, 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, can also subject the Fund to many of the same risks associated with direct cyber security breaches. Although the Fund has established risk management systems designed to reduce the risks associated with cyber security, 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 &lt;/span&gt;&lt;span style="color:#000000;font-family:Arial;font-size:9.00pt;"&gt;providers.&lt;/span&gt;</rr: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="color:#000000;font-family:Arial;font-size:9.00pt;"&gt;company, industry or sector of the market.&lt;/span&gt;</rr:RiskTextBlock>

As a result, &lt;/span&gt;&lt;span style="color:#000000;font-family:Arial;font-size:9.00pt;margin-left:0%;"&gt;the Fund may be included in one or more index-tracking exchange-traded funds or mutual funds. Being a component security of such a vehicle could greatly affect the trading activity involving the Fund&#x2019;s shares, the size of the Fund and the market volatility of the Fund. 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. As a result, the Fund&#x2019;s net asset value could be negatively impacted and the Fund&#x2019;s market price may be below the Fund&#x2019;s net asset value during certain periods. In addition, index rebalances may &lt;/span&gt;&lt;span style="color:#000000;font-family:Arial;font-size:9.00pt;"&gt;potentially result in increased trading activity in the Fund's shares.&lt;/span&gt;</rr:RiskTextBlock>

These companies may be adversely affected by rapidly changing technologies, short product life cycles, fierce competition, aggressive pricing and reduced profit margins, the loss of patent, copyright and trademark protections, cyclical market patterns, evolving industry standards and frequent new product introductions. In addition, information technology companies are particularly vulnerable to federal, state and local government regulation, and competition and consolidation, both domestically and internationally, including competition from foreign competitors with lower production costs. Information technology companies also heavily rely on intellectual property rights &lt;/span&gt;&lt;span style="font-family:Arial;font-size:9.00pt;"&gt;and may be adversely affected by the loss or impairment of those rights.&lt;/span&gt;</rr:RiskTextBlock>

Decisions by market makers or authorized participants to reduce their 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. &lt;/span&gt;&lt;span style="color:#000000;font-family:Arial;font-size:9.00pt;margin-left:0%;"&gt;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="color:#000000;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;</rr: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. In addition, local, regional or global events such as war, acts of terrorism, market manipulation, government defaults, government shutdowns, regulatory actions, political changes, diplomatic developments, the imposition of sanctions and other similar measures, spread of infectious diseases or other public health issues, recessions, natural disasters, or other events could have a significant negative impact on the Fund and its investments. Any of such circumstances could have a materially negative impact on the value of the Fund&#x2019;s shares, the liquidity of an investment, and may result in increased market volatility. During any such events, the Fund&#x2019;s shares may trade at increased premiums or discounts to their net asset value, the bid/ask spread on the Fund&#x2019;s shares may widen and the returns on investment may &lt;/span&gt;&lt;span style="color:#000000;font-family:Arial;font-size:9.00pt;"&gt;fluctuate.&lt;/span&gt;</rr: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;</rr:RiskTextBlock>

The term &#x201c;developed market companies&#x201d; means those companies (i) whose securities are traded principally on a stock exchange in a developed market country, (ii) with 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. The Sub-Advisor considers Australia, Austria, Belgium, Canada, Denmark, Finland, France, Germany, Hong Kong, Ireland, Israel, Italy, Japan, Luxembourg, the Netherlands, New Zealand, Norway, Portugal, Singapore, Spain, Sweden, Switzerland, the United Kingdom and the United States to be developed market countries. However, this list may change in response to market and geopolitical events. Under normal market conditions, the Fund will invest in at least three countries and at least 40% of its &lt;/span&gt;&lt;span style="color:#000000;font-family:Arial;font-size:9.00pt;"&gt;net assets in countries other than the United States.  &lt;/span&gt;&lt;span style="color:#000000;font-family:Arial;font-size:9.00pt;margin-left:0%;"&gt;The goal of this strategy is to capture upside price movements in rising markets and reduce downside risk when markets decline. To implement this strategy, in selecting securities for the Fund from a portfolio of eligible securities, the Sub-Advisor employs volatility forecasting models to forecast future expected volatility. 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 &lt;/span&gt;&lt;span style="color:#000000;font-family:Arial;font-size:9.00pt;"&gt;of holdings and the weightings of particular holdings) in connection with its active management of the Fund.  &lt;/span&gt;&lt;span style="color:#000000;font-family:Arial;font-size:9.00pt;margin-left:0%;"&gt;To begin, the Sub-Advisor gathers pricing and generates return data for the starting universe, which is comprised of common stocks and depositary receipts of large and mid-cap securities across developed markets, which securities have been pre-screened by the Sub-Advisor to ensure they are liquid and accessible for trading. The Sub-Advisor then conducts volatility forecasts for securities comprising the starting universe and ranks them from low to high based on their volatility forecasts. The Sub-Advisor targets 100-400 securities for inclusion in the portfolio based on future expected volatility. Once the final portfolio is selected, the Sub-Advisor measures co-movements of the selected securities using statistical techniques designed to reduce estimation error. In the final portfolio construction, the Sub-Advisor gives larger weights to securities with lower future expected volatility and has the ability to adjust how aggressive the weighting scheme is depending on market conditions. The Sub-Advisor periodically rebalances and reallocates the portfolio using this methodology, which may result in higher levels &lt;/span&gt;&lt;span style="color:#000000;font-family:Arial;font-size:9.00pt;"&gt;of portfolio turnover. The Fund may invest in securities that are denominated in U.S. or non-U.S. currencies.  &lt;/span&gt;&lt;span style="font-family:Arial;font-size:9.00pt;margin-left:0%;"&gt;As of October 31, 2024 the Fund had significant investments in financial companies, 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; To the extent the Fund invests a significant portion of its assets in a given jurisdiction or investment sector, the Fund may be exposed to the risks associated with that jurisdiction or investment sector.&lt;/span&gt;</rr: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 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;</rr:RiskTextBlock>

As a means to fight inflation, which remains at elevated levels, the Federal Reserve and certain foreign central banks have raised interest rates&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;line-height:10.80pt;"&gt;  &lt;/span&gt;&lt;span style="font-family:Arial;font-size:9.00pt;"&gt;however, the Federal Reserve has recently lowered interest rates and may continue to do so. U.S. regulators have proposed several changes to market and issuer &lt;/span&gt;&lt;span style="font-family:Arial;font-size:9.00pt;margin-left:0%;"&gt;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. Recent and potential future bank failures could result in disruption to the broader banking industry or markets generally and reduce confidence in financial institutions and the economy as a whole, which may also heighten market volatility and reduce liquidity. &lt;/span&gt;&lt;span style="font-family:Arial;font-size:9.00pt;"&gt;Additionally, challenges in commercial real estate &lt;/span&gt;&lt;span style="font-family:Arial;font-size:9.00pt;margin-left:0%;"&gt;markets, including rising interest rates, declining valuations and increasing vacancies, could have a broader impact on financial markets.&lt;/span&gt;&lt;span style="font-family:Arial;font-size:9.00pt;"&gt; The ongoing adversarial political climate in the United States, as well as political and diplomatic events both domestic &lt;/span&gt;&lt;span style="font-family:Arial;font-size:9.00pt;margin-left:0%;"&gt;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. &lt;/span&gt;&lt;span style="font-family:Arial;font-size:9.00pt;"&gt;The change in administration resulting from &lt;/span&gt;&lt;span style="font-family:Arial;font-size:9.00pt;margin-left:0%;"&gt;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.&lt;/span&gt;&lt;span style="font-family:Arial;font-size:9.00pt;"&gt; Other unexpected political, regulatory and diplomatic events within the &lt;/span&gt;&lt;span style="font-family:Arial;font-size:9.00pt;margin-left:0%;"&gt;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, &lt;/span&gt;&lt;span style="font-family:Arial;font-size:9.00pt;"&gt;Iran, Hamas and &lt;/span&gt;&lt;span style="font-family:Arial;font-size:9.00pt;margin-left:0%;"&gt;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 and other matters. For example, the United States has imposed trade barriers and restrictions 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. &lt;/span&gt;&lt;span style="font-family:Arial;font-size:9.00pt;"&gt;A public health crisis and the ensuing &lt;/span&gt;&lt;span style="font-family:Arial;font-size:9.00pt;margin-left:0%;"&gt;policies enacted by governments and central banks &lt;/span&gt;&lt;span style="font-family:Arial;font-size:9.00pt;"&gt;may cause significant volatility and uncertainty in global financial markets, &lt;/span&gt;&lt;span style="font-family:Arial;font-size:9.00pt;margin-left:0%;"&gt;negatively impacting global growth prospects. &lt;/span&gt;&lt;span style="font-family:Arial;font-size:9.00pt;"&gt;As the COVID-19 global pandemic illustrated, such events may affect certain &lt;/span&gt;&lt;span style="font-family:Arial;font-size:9.00pt;margin-left:0%;"&gt;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. &lt;/span&gt;&lt;span style="font-family:Arial;font-size:9.00pt;"&gt;Additionally, cyber security breaches of both &lt;/span&gt;&lt;span style="font-family:Arial;font-size:9.00pt;margin-left:0%;"&gt;government and non-government entities could have negative impacts on infrastructure and the ability of such entities, including the Fund, to operate properly.&lt;/span&gt;&lt;span style="font-family:Arial;font-size:9.00pt;"&gt; These events, and any other future events, may adversely affect the prices and liquidity of the Fund&#x2019;s portfolio investments and could result in disruptions in the trading markets.&lt;/span&gt;</rr:RiskTextBlock>

A breach in cyber &lt;/span&gt;&lt;span style="color:#000000;font-family:Arial;font-size:9.00pt;margin-left:0%;"&gt;security refers to both intentional and unintentional events that may cause the Fund to lose proprietary information, suffer data corruption or lose operational capacity. Such events could cause the Fund to incur regulatory penalties, reputational damage, 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. In addition, 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, can also subject the Fund to many of the same risks associated with direct cyber security breaches. Although the Fund has established risk management systems designed to reduce the risks associated with cyber security, 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 &lt;/span&gt;&lt;span style="color:#000000;font-family:Arial;font-size:9.00pt;"&gt;providers.&lt;/span&gt;</rr: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;</rr: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.

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;</rr:RiskTextBlock>

The Fund defines small- and mid-capitalization companies as those that, at the time of investment, have a market capitalization between the minimum and maximum market capitalization of a widely recognized index of small- or mid-capitalization companies, respectively, based upon the composition of the index at the time of investment. As of October 31, &lt;/span&gt;&lt;span style="font-family:Arial;font-size:9.00pt;"&gt;2024, the Fund considers small- and mid-capitalization companies to be those with a market capitalization between &lt;/span&gt;&lt;span style="font-family:Arial;font-size:9.00pt;margin-left:0%;"&gt;$100 million and $&lt;/span&gt;&lt;span style="font-family:Arial;font-size:9.00pt;"&gt;30 billion. The exact size of the companies included will change with market conditions and the Fund will &lt;/span&gt;&lt;span style="font-family:Arial;font-size:9.00pt;margin-left:0%;"&gt;not automatically sell or cease to purchase a stock that it already owns due to changes in market conditions. The Fund may &lt;/span&gt;&lt;span style="font-family:Arial;font-size:9.00pt;"&gt;also invest in the equity securities of real estate 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="color:#000000;font-family:Arial;font-size:9.00pt;margin-left:0%;"&gt;The goal of this strategy is to capture upside price movements in rising markets and reduce downside risk when markets decline. To implement this strategy, the Sub-Advisor employs volatility forecasting models to forecast future expected volatility. Volatility is a statistical measure of the magnitude of changes in the Fund&#x2019;s return without regard to the direction of those changes, and higher volatility generally indicates higher risk and is often reflected by frequent and sometimes significant movements &lt;/span&gt;&lt;span style="color:#000000;font-family:Arial;font-size:9.00pt;margin-left:0%;"&gt;up and down in value. A volatility forecast is a statistical estimate of future expected volatility that uses historical price returns over multiple time frames as inputs to determine volatility forecasts for individual equities. Volatility forecasts are a unique estimate of volatility that the Sub-Advisor believes may be more responsive and accurate in predicting future volatility than historical standard deviation. These statistical models attempt to measure observed characteristics of volatility over time in order to estimate the forecasts. 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 &lt;/span&gt;&lt;span style="color:#000000;font-family:Arial;font-size:9.00pt;"&gt;of particular holdings) in connection with its active management of the Fund.  &lt;/span&gt;&lt;span style="color:#000000;font-family:Arial;font-size:9.00pt;margin-left:0%;"&gt;To begin, the Sub-Advisor gathers historical pricing data and generates return data for the starting universe, which is comprised of common stocks listed and traded on U.S. national securities exchanges that are issued by small- and/or mid-capitalization companies. The Sub-Advisor then uses this data in volatility forecasting models to rank the securities comprising the starting universe from low to high based on their volatility forecasts. Once the final portfolio is selected, the Sub-Advisor gives larger weights to securities with lower future expected volatility; however, the Sub-Advisor may choose to deviate from such approach depending on current market conditions across various market sectors. The Sub-Advisor periodically rebalances and reallocates &lt;/span&gt;&lt;span style="color:#000000;font-family:Arial;font-size:9.00pt;"&gt;the portfolio using this methodology, which may result in higher levels of portfolio turnover.  &lt;/span&gt;&lt;span style="font-family:Arial;font-size:9.00pt;margin-left:0%;"&gt;As of October 31, 2024, the Fund had significant investments in financial companies, although this may change from time to time.&lt;/span&gt;&lt;span style="font-family:Arial;font-size:9.00pt;"&gt; To the extent the Fund invests a significant portion of its assets in a given jurisdiction or investment sector, the Fund may be exposed to the risks associated with that jurisdiction or investment sector.&lt;/span&gt;</rr:StrategyNarrativeTextBlock>

As a means to fight inflation, which remains at elevated levels, the Federal Reserve and certain foreign central banks have raised interest rates&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;line-height:10.80pt;"&gt;  &lt;/span&gt;&lt;span style="font-family:Arial;font-size:9.00pt;"&gt;however, the Federal Reserve has recently lowered interest rates and may continue to do so. U.S. regulators have proposed several changes to market and issuer &lt;/span&gt;&lt;span style="font-family:Arial;font-size:9.00pt;margin-left:0%;"&gt;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. Recent and potential future bank failures could result in disruption to the broader banking industry or markets generally and reduce confidence in financial institutions and the economy as a whole, which may also heighten market volatility and reduce liquidity. &lt;/span&gt;&lt;span style="font-family:Arial;font-size:9.00pt;"&gt;Additionally, challenges in commercial real estate &lt;/span&gt;&lt;span style="font-family:Arial;font-size:9.00pt;margin-left:0%;"&gt;markets, including rising interest rates, declining valuations and increasing vacancies, could have a broader impact on financial markets.&lt;/span&gt;&lt;span style="font-family:Arial;font-size:9.00pt;"&gt; The ongoing adversarial political climate in the United States, as well as political and diplomatic events both domestic &lt;/span&gt;&lt;span style="font-family:Arial;font-size:9.00pt;margin-left:0%;"&gt;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. &lt;/span&gt;&lt;span style="font-family:Arial;font-size:9.00pt;"&gt;The change in administration resulting from &lt;/span&gt;&lt;span style="font-family:Arial;font-size:9.00pt;margin-left:0%;"&gt;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.&lt;/span&gt;&lt;span style="font-family:Arial;font-size:9.00pt;"&gt; Other unexpected political, regulatory and diplomatic events within the &lt;/span&gt;&lt;span style="font-family:Arial;font-size:9.00pt;margin-left:0%;"&gt;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, &lt;/span&gt;&lt;span style="font-family:Arial;font-size:9.00pt;"&gt;Iran, Hamas and &lt;/span&gt;&lt;span style="font-family:Arial;font-size:9.00pt;margin-left:0%;"&gt;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 and other matters. For example, the United States has imposed trade barriers and restrictions on China. In addition, the Chinese government is engaged in a longstanding dispute with Taiwan, continually threatening an &lt;/span&gt;&lt;span style="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. &lt;/span&gt;&lt;span style="font-family:Arial;font-size:9.00pt;"&gt;A public health crisis and the ensuing &lt;/span&gt;&lt;span style="font-family:Arial;font-size:9.00pt;margin-left:0%;"&gt;policies enacted by governments and central banks &lt;/span&gt;&lt;span style="font-family:Arial;font-size:9.00pt;"&gt;may cause significant volatility and uncertainty in global financial markets, &lt;/span&gt;&lt;span style="font-family:Arial;font-size:9.00pt;margin-left:0%;"&gt;negatively impacting global growth prospects. &lt;/span&gt;&lt;span style="font-family:Arial;font-size:9.00pt;"&gt;As the COVID-19 global pandemic illustrated, such events may affect certain &lt;/span&gt;&lt;span style="font-family:Arial;font-size:9.00pt;margin-left:0%;"&gt;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. &lt;/span&gt;&lt;span style="font-family:Arial;font-size:9.00pt;"&gt;Additionally, cyber security breaches of both &lt;/span&gt;&lt;span style="font-family:Arial;font-size:9.00pt;margin-left:0%;"&gt;government and non-government entities could have negative impacts on infrastructure and the ability of such entities, including the Fund, to operate properly.&lt;/span&gt;&lt;span style="font-family:Arial;font-size:9.00pt;"&gt; These events, and any other future events, may adversely affect the prices and liquidity of the Fund&#x2019;s portfolio investments and could result in disruptions in the trading markets.&lt;/span&gt;</rr:RiskTextBlock>

A breach in cyber &lt;/span&gt;&lt;span style="color:#000000;font-family:Arial;font-size:9.00pt;margin-left:0%;"&gt;security refers to both intentional and unintentional events that may cause the Fund to lose proprietary information, suffer data corruption or lose operational capacity. Such events could cause the Fund to incur regulatory penalties, reputational damage, 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. In addition, 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, can also subject the Fund to many of the same risks associated with direct cyber security breaches. Although the Fund has established risk management systems designed to reduce the risks associated with cyber security, 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 &lt;/span&gt;&lt;span style="color:#000000;font-family:Arial;font-size:9.00pt;"&gt;providers.&lt;/span&gt;</rr: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.

Although the Fund and the Fund's investment advisor seek to reduce these operational risks through &lt;/span&gt;&lt;span style="color:#000000;font-family:Arial;font-size:9.00pt;"&gt;controls and procedures, there is no way to completely protect against such risks.&lt;/span&gt;</rr: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;</rr: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 earnings, the value of the &lt;/span&gt;&lt;span style="color:#000000;font-family:Arial;font-size:9.00pt;"&gt;Fund will generally decline when investors anticipate or experience rising interest rates.&lt;/span&gt;</rr:RiskTextBlock>

The Fund&#x2019;s portfolio may include equity securities issued by U.S. and non-U.S. companies, including American &lt;/span&gt;&lt;span style="color:#000000;font-family:Arial;font-size:9.00pt;"&gt;Depositary Receipts (&lt;/span&gt;&lt;span style="color:#000000;font-family:Arial;font-size:9.00pt;font-style:italic;"&gt;&#x201c;ADRs&#x201d;&lt;/span&gt;&lt;span style="color:#000000;font-family:Arial;font-size:9.00pt;"&gt;).

The profit which &lt;/span&gt;&lt;span style="color:#000000;font-family:Arial;font-size:9.00pt;margin-left:0%;"&gt;may be realized is the &#x201c;spread,&#x201d; or difference in price between the trading price of the target company&#x2019;s stock following the announcement of the corporate event and the contractual price to be paid for the target company stock in the future when the transaction closes. Such a spread typically exists due to the uncertainty regarding whether the announced merger, acquisition or other corporate event will close, and if it closes, that such transaction will be at the initially proposed economic &lt;/span&gt;&lt;span style="color:#000000;font-family:Arial;font-size:9.00pt;margin-left:0%;"&gt;terms. Only the securities of companies involved in publicly-announced transactions are eligible for inclusion in the Fund&#x2019;s portfolio. Merger arbitrage, when executed well, has the potential to produce a differentiated and robust absolute return stream.  &lt;/span&gt;&lt;span style="font-family:Arial;font-size:9.00pt;margin-left:0%;"&gt;In deciding upon which opportunities to invest in, the Sub-Advisor assesses a number of factors, including, but not limited to, the probability that the merger will be completed, the attractiveness of a transaction relative to others in the arbitrage universe, and any unique risks which may decrease the likelihood that a transaction will close. Every transaction has its unique set of elements, and the Sub-Advisor&#x2019;s investment process relies on real-time quantitative-based research to evaluate how attractive each transaction is relative to other deals in the arbitrage universe. The Fund adheres to that quantitative criteria to separate which deals to invest in and which to avoid. In the event that the Sub-Advisor cannot find enough securities that satisfy its investment criteria, the Fund may hold a significant amount of cash or cash equivalents. During periods of market stress or when merger and acquisition activity is low, the availability of transactions of the type in which the Fund invests may be significantly limited. To the extent the Fund has a large cash position, the Fund is less able to satisfy its investment objective. As of October 31, &lt;/span&gt;&lt;span style="font-family:Arial;font-size:9.00pt;"&gt;2024, 28.63% of the Fund&#x2019;s assets consisted of investable cash and/or cash equivalents. Due to the current market environment, it is expected that the Fund may maintain a large cash position for the foreseeable future.  &lt;/span&gt;&lt;span style="color:#000000;font-family:Arial;font-size:9.00pt;margin-left:0%;"&gt;The Sub-Advisor intends to engage in short selling. Short selling is a technique that allows an investor (such as the Fund) to profit from the falling price of a security. It involves selling a security that has been borrowed from a third-party with the intention of buying an identical security back at a later date to return to that third-party. The Fund&#x2019;s short positions may be significant, however, the Fund will at all times comply with the regulatory requirements of the Securities and Exchange Commission with respect to coverage of the Fund&#x2019;s short positions. The Fund intends to invest the proceeds from a sale of a borrowed security in cash or cash equivalents, including money market funds. The Fund&#x2019;s investment strategy may include active and frequent &lt;/span&gt;&lt;span style="color:#000000;font-family:Arial;font-size:9.00pt;"&gt;trading.  &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 10% of its net assets in stock, warrants, and other securities of special purpose acquisition companies (&lt;/span&gt;&lt;span style="color:#000000;font-family:Arial;font-size:9.00pt;font-style:italic;"&gt;&#x201c;SPACs&#x201d;&lt;/span&gt;&lt;span style="color:#000000;font-family:Arial;font-size:9.00pt;"&gt;). A SPAC is a publicly listed acquisition vehicle, whereby one or more sponsors raise a pool of capital with the special &lt;/span&gt;&lt;span style="color:#000000;font-family:Arial;font-size:9.00pt;margin-left:0%;"&gt;purpose of acquiring a private operating company. SPACs often have pre-determined time frames to merge with an operating company (typically two years), and if no merger takes place during that time frame the SPAC will liquidate. A SPAC generally offers units, each comprised of one share of common stock and a warrant (or portion of a warrant) to purchase common stock. A warrant is a security that allows its holder to purchase a specified amount of common stock at a specified price for a specified time. Unless and until an acquisition is completed, a SPAC generally invests its assets (less a portion retained to cover expenses) in U.S. government securities, money market securities and cash. If an acquisition that meets the requirements for the SPAC &lt;/span&gt;&lt;span style="color:#000000;font-family:Arial;font-size:9.00pt;"&gt;is not completed within a pre-established period, the invested funds are returned to the entity&#x2019;s shareholders.  &lt;/span&gt;&lt;span style="color:#000000;font-family:Arial;font-size:9.00pt;margin-left:0%;"&gt;The Fund will generally dispose of SPAC interests held by the Fund prior to the completion of an acquisition. Depending on the relative market price of the SPAC securities and the net asset value of the underlying U.S. government securities, money market securities and cash held by the SPAC, the Fund may either sell the securities at their current market price or redeem &lt;/span&gt;&lt;span style="color:#000000;font-family:Arial;font-size:9.00pt;"&gt;them with the SPAC in accordance with the redemption terms applicable to such securities.  &lt;/span&gt;&lt;span style="font-family:Arial;font-size:9.00pt;margin-left:0%;"&gt;As of October 31, 2024, the Fund had significant investments in health care companies, although this may change from time to time. To the extent the Fund invests a significant portion of its assets in a given jurisdiction or investment sector, the Fund &lt;/span&gt;&lt;span style="font-family:Arial;font-size:9.00pt;"&gt;may be exposed to the risks associated with that jurisdiction or investment sector.  &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;</rr:StrategyNarrativeTextBlock>

As a means to fight inflation, which remains at elevated levels, the Federal Reserve and certain foreign central banks have raised interest rates&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;line-height:10.80pt;"&gt;  &lt;/span&gt;&lt;span style="font-family:Arial;font-size:9.00pt;"&gt;however, the Federal Reserve has recently lowered interest rates and may continue to do so. U.S. regulators have proposed several changes to market and issuer &lt;/span&gt;&lt;span style="font-family:Arial;font-size:9.00pt;margin-left:0%;"&gt;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. Recent and potential future bank failures could result in disruption to the broader banking industry or markets generally and reduce confidence in financial institutions and the economy as a whole, which may also heighten market volatility and reduce liquidity. &lt;/span&gt;&lt;span style="font-family:Arial;font-size:9.00pt;"&gt;Additionally, challenges in commercial real estate &lt;/span&gt;&lt;span style="font-family:Arial;font-size:9.00pt;margin-left:0%;"&gt;markets, including rising interest rates, declining valuations and increasing vacancies, could have a broader impact on financial markets.&lt;/span&gt;&lt;span style="font-family:Arial;font-size:9.00pt;"&gt; The ongoing adversarial political climate in the United States, as well as political and diplomatic events both domestic &lt;/span&gt;&lt;span style="font-family:Arial;font-size:9.00pt;margin-left:0%;"&gt;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. &lt;/span&gt;&lt;span style="font-family:Arial;font-size:9.00pt;"&gt;The change in administration resulting from &lt;/span&gt;&lt;span style="font-family:Arial;font-size:9.00pt;margin-left:0%;"&gt;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.&lt;/span&gt;&lt;span style="font-family:Arial;font-size:9.00pt;"&gt; Other unexpected political, regulatory and diplomatic events within the &lt;/span&gt;&lt;span style="font-family:Arial;font-size:9.00pt;margin-left:0%;"&gt;U.S. and abroad may affect investor and consumer confidence and may adversely impact financial markets and the broader economy. For example, &lt;/span&gt;&lt;span style="font-family:Arial;font-size:9.00pt;"&gt;ongoing armed conflicts between Russia and Ukraine in Europe and among Israel, Iran,&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;Hamas and &lt;/span&gt;&lt;span style="font-family:Arial;font-size:9.00pt;margin-left:0%;"&gt;other militant groups in the Middle East, have &lt;/span&gt;&lt;span style="font-family:Arial;font-size:9.00pt;"&gt;caused and could continue to cause significant market disruptions and volatility &lt;/span&gt;&lt;span style="font-family:Arial;font-size:9.00pt;margin-left:0%;"&gt;within the markets in Russia, Europe, &lt;/span&gt;&lt;span style="font-family:Arial;font-size:9.00pt;"&gt;the Middle East and the United States. The hostilities and sanctions resulting from those &lt;/span&gt;&lt;span style="font-family:Arial;font-size:9.00pt;margin-left:0%;"&gt;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 and other matters. For example, the United States has imposed trade barriers and restrictions 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. &lt;/span&gt;&lt;span style="font-family:Arial;font-size:9.00pt;"&gt;A public health crisis and the ensuing &lt;/span&gt;&lt;span style="font-family:Arial;font-size:9.00pt;margin-left:0%;"&gt;policies enacted by governments and central banks &lt;/span&gt;&lt;span style="font-family:Arial;font-size:9.00pt;"&gt;may cause significant volatility and uncertainty in global financial markets, &lt;/span&gt;&lt;span style="font-family:Arial;font-size:9.00pt;margin-left:0%;"&gt;negatively impacting global growth prospects. &lt;/span&gt;&lt;span style="font-family:Arial;font-size:9.00pt;"&gt;As the COVID-19 global pandemic illustrated, such events may affect certain &lt;/span&gt;&lt;span style="font-family:Arial;font-size:9.00pt;margin-left:0%;"&gt;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. &lt;/span&gt;&lt;span style="font-family:Arial;font-size:9.00pt;"&gt;Additionally, cyber security breaches of both &lt;/span&gt;&lt;span style="font-family:Arial;font-size:9.00pt;margin-left:0%;"&gt;government and non-government entities could have negative impacts on infrastructure and the ability of such entities, including the Fund, to operate properly.&lt;/span&gt;&lt;span style="font-family:Arial;font-size:9.00pt;"&gt; These events, and any other future events, may adversely affect the prices and liquidity of the Fund&#x2019;s portfolio investments and could result in disruptions in the trading markets.&lt;/span&gt;</rr:RiskTextBlock>

A breach in cyber &lt;/span&gt;&lt;span style="color:#000000;font-family:Arial;font-size:9.00pt;margin-left:0%;"&gt;security refers to both intentional and unintentional events that may cause the Fund to lose proprietary information, suffer data corruption or lose operational capacity. Such events could cause the Fund to incur regulatory penalties, reputational damage, 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. In addition, 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, can also subject the Fund to many of the same risks associated with direct cyber security breaches. Although the Fund has established risk management systems designed to reduce the risks associated with cyber security, 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 &lt;/span&gt;&lt;span style="color:#000000;font-family:Arial;font-size:9.00pt;"&gt;providers.&lt;/span&gt;</rr:RiskTextBlock>

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="color:#000000;font-family:Arial;font-size:9.00pt;"&gt;company, industry or sector of the market.&lt;/span&gt;</rr:RiskTextBlock>

In the case of an investment in a potential target company, if the proposed transaction appears likely not to be consummated, in fact is not consummated, or is delayed, the market price of the security will usually decline sharply, resulting in a loss to the Fund. The risk/reward payout of merger arbitrage strategies typically is asymmetric, with the losses in failed transactions often far exceeding the gains in successful transactions. During periods of market stress, the availability of transactions of the type in which the Fund invests may be significantly limited. In the event that the Sub-Advisor cannot find enough securities that satisfy its investment criteria, the Fund may hold a significant amount of cash or cash equivalents. During periods of market stress or when merger and acquisition activity is low, the availability of transactions of the type in which the Fund invests may be significantly limited. To the extent the Fund has a large cash position, the Fund is less able to satisfy its investment objective. As of October 31, &lt;/span&gt;&lt;span style="font-family:Arial;font-size:9.00pt;"&gt;2024, 28.63% of the Fund&#x2019;s assets consisted of &lt;/span&gt;&lt;span style="font-family:Arial;font-size:9.00pt;margin-left:0%;"&gt;investable cash and/or cash equivalents. Due to the current market environment, it is expected that the Fund may maintain &lt;/span&gt;&lt;span style="font-family:Arial;font-size:9.00pt;"&gt;a large cash position for the foreseeable future.&lt;/span&gt;</rr: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 &lt;/span&gt;&lt;span style="color:#000000;font-family:Arial;font-size:9.00pt;margin-left:0%;"&gt;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;</rr:RiskTextBlock>

To the extent a SPAC is invested in cash or similar securities, this may affect the Fund&#x2019;s ability to meet its investment objective. SPACs have no operating history or ongoing business other than seeking acquisitions. The value of a SPAC&#x2019;s securities is particularly dependent on the ability of its management to identify and complete a profitable acquisition. There is no guarantee that the SPACs in which the Fund may invest will complete an acquisition or that any acquisitions completed by the SPACs in which the Fund may invest will be profitable. SPACs in which the Fund may invest may pursue acquisitions only within a certain industry or geographic location, which may increase the volatility of their prices. An investment in SPACs, which are typically traded in the over-the-counter &lt;/span&gt;&lt;span style="color:#000000;font-family:Arial;font-size:9.00pt;"&gt;market, may also have little or no liquidity and may be subject to restrictions on resale.&lt;/span&gt;</rr:RiskTextBlock>

As a means to fight inflation, which remains at elevated levels, the Federal Reserve and certain foreign central banks have raised interest rates&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;line-height:10.80pt;"&gt;  &lt;/span&gt;&lt;span style="font-family:Arial;font-size:9.00pt;"&gt;however, the Federal Reserve has recently lowered interest rates and may continue to do so.

Recent and potential future bank failures could result in disruption to the broader banking industry or markets generally and reduce confidence in financial institutions and the economy as a whole, which may also heighten market volatility and reduce liquidity. &lt;/span&gt;&lt;span style="font-family:Arial;font-size:9.00pt;"&gt;Additionally, challenges in commercial real estate &lt;/span&gt;&lt;span style="font-family:Arial;font-size:9.00pt;margin-left:0%;"&gt;markets, including rising interest rates, declining valuations and increasing vacancies, could have a broader impact on financial markets.&lt;/span&gt;&lt;span style="font-family:Arial;font-size:9.00pt;"&gt; The ongoing adversarial political climate in the United States, as well as political and diplomatic events both domestic &lt;/span&gt;&lt;span style="font-family:Arial;font-size:9.00pt;margin-left:0%;"&gt;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. &lt;/span&gt;&lt;span style="font-family:Arial;font-size:9.00pt;"&gt;The change in administration resulting from &lt;/span&gt;&lt;span style="font-family:Arial;font-size:9.00pt;margin-left:0%;"&gt;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.&lt;/span&gt;&lt;span style="font-family:Arial;font-size:9.00pt;"&gt; Other unexpected political, regulatory and diplomatic events within the &lt;/span&gt;&lt;span style="font-family:Arial;font-size:9.00pt;margin-left:0%;"&gt;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, &lt;/span&gt;&lt;span style="font-family:Arial;font-size:9.00pt;"&gt;Iran, Hamas and &lt;/span&gt;&lt;span style="font-family:Arial;font-size:9.00pt;margin-left:0%;"&gt;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 and other matters. For example, the United States has imposed trade barriers and restrictions 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. &lt;/span&gt;&lt;span style="font-family:Arial;font-size:9.00pt;"&gt;A public health crisis and the ensuing &lt;/span&gt;&lt;span style="font-family:Arial;font-size:9.00pt;margin-left:0%;"&gt;policies enacted by governments and central banks &lt;/span&gt;&lt;span style="font-family:Arial;font-size:9.00pt;"&gt;may cause significant volatility and uncertainty in global financial markets, &lt;/span&gt;&lt;span style="font-family:Arial;font-size:9.00pt;margin-left:0%;"&gt;negatively impacting global growth prospects. &lt;/span&gt;&lt;span style="font-family:Arial;font-size:9.00pt;"&gt;As the COVID-19 global pandemic illustrated, such events may affect certain &lt;/span&gt;&lt;span style="font-family:Arial;font-size:9.00pt;margin-left:0%;"&gt;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. &lt;/span&gt;&lt;span style="font-family:Arial;font-size:9.00pt;"&gt;Additionally, cyber security breaches of both &lt;/span&gt;&lt;span style="font-family:Arial;font-size:9.00pt;margin-left:0%;"&gt;government and non-government entities could have negative impacts on infrastructure and the ability of such entities, including the Fund, to operate properly.&lt;/span&gt;&lt;span style="font-family:Arial;font-size:9.00pt;"&gt; These events, and any other future events, may adversely affect the prices and liquidity of the Fund&#x2019;s portfolio investments and could result in disruptions in the trading markets.&lt;/span&gt;</rr:RiskTextBlock>

Credit risk refers to &lt;/span&gt;&lt;span style="color:#000000;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 &lt;/span&gt;&lt;span style="color:#000000;font-family:Arial;font-size:9.00pt;"&gt;more difficult to value than common stock.&lt;/span&gt;</rr:RiskTextBlock>

Derivative prices are highly volatile and may fluctuate substantially during a short period of time. &lt;/span&gt;&lt;span style="font-family:Arial;font-size:9.00pt;margin-left:0%;"&gt;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="font-family:Arial;font-size:9.00pt;"&gt;effects of market volatility on share price.&lt;/span&gt;</rr: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;</rr: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;</rr:RiskTextBlock>

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 full impact of the COVID-19 pandemic on state and political subdivisions&#x2019; ability to make payments on debt obligations is impossible to predict, but could negatively impact the value of bonds, the ability of state and political subdivisions to make payments when due and the performance of the Fund. Municipal securities issued by U.S. territories, including, but not limited to, Puerto Rico, the U.S. Virgin Islands and Guam, may face a heightened risk of default due to adverse economic conditions in such territories, which could negatively impact &lt;/span&gt;&lt;span style="color:#000000;font-family:Arial;font-size:9.00pt;"&gt;the value of any Fund investments in U.S. territorial issuers and the Fund&#x2019;s investment performance.&lt;/span&gt;</rr: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 &lt;/span&gt;&lt;span style="color:#000000;font-family:Arial;font-size:9.00pt;margin-left:0%;"&gt;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;</rr:RiskTextBlock>

The private activity bonds in which the Fund may invest may be negatively impacted by conditions affecting either the general credit of the private enterprise or the project itself. The Fund&#x2019;s private activity bond holdings may also pay interest subject to the federal alternative minimum tax on individuals.

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 &lt;/span&gt;&lt;span style="font-family:Arial;font-size:9.00pt;"&gt;Fund's&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;shares. Authorized Participants who purchase or redeem Fund shares on days &lt;/span&gt;&lt;span style="font-family:Arial;font-size:9.00pt;margin-left:0%;"&gt;when the Fund is holding fair-valued securities may receive fewer or more shares, or lower or higher redemption proceeds, &lt;/span&gt;&lt;span style="color:#000000;font-family:Arial;font-size:9.00pt;margin-left:0%;"&gt;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;</rr:RiskTextBlock>

Indexes do not charge management fees or brokerage expenses, and no such fees or expenses were deducted from the index performance shown. Indexes are unmanaged and an investor cannot invest directly in an index. The Blended Benchmark returns are calculated by using the monthly return of the two indices during each period shown above. At the beginning of each month the two indices are rebalanced to a 50-50 ratio to account for divergence from that ratio that occurred during the course of each month. The monthly returns are then compounded for each period shown above, giving the performance for the Blended Benchmark for each period shown above.&lt;/span&gt;</rr:PerformanceAdditionalMarketIndex>

In general, interest on Municipal Securities issued by or on behalf of the State of New York will be exempt from the New York individual income tax. Municipal Securities issued by or on behalf of territories or possessions of the U.S. and/or the political subdivisions, agencies, authorities and other instrumentalities of such territories or possessions (collectively, &lt;/span&gt;&lt;span style="color:#000000;font-family:Arial;font-size:9.00pt;font-style:italic;"&gt;&#x201c;Territorial Obligations&#x201d;&lt;/span&gt;&lt;span style="color:#000000;font-family:Arial;font-size:9.00pt;"&gt;) will pay interest that is exempt from regular federal income taxes and &lt;/span&gt;&lt;span style="color:#000000;font-family:Arial;font-size:9.00pt;margin-left:0%;"&gt;the New York individual income tax. The Fund may invest up to 100% of its net assets in Municipal Securities that pay interest that generates income subject to the federal alternative minimum tax on individuals. For tax years beginning after December 31, 2022, interest on the bonds may affect the corporate alternative minimum tax for certain corporations. The types of Municipal Securities in which the Fund may invest as a part of its principal investment strategy include municipal general obligation bonds, municipal revenue bonds and private activity bonds (including without limitation industrial development bonds). Industrial &lt;/span&gt;&lt;span style="color:#000000;font-family:Arial;font-size:9.00pt;margin-left:0%;"&gt;development bonds are revenue bonds issued by or on behalf of public authorities to obtain funds to finance various public and/or privately operated facilities, including those for business and manufacturing, housing, sports, pollution control, airport, mass transit, port and parking facilities. The Fund may invest in Municipal Securities of any duration and any maturity, however, &lt;/span&gt;&lt;span style="color:#000000;font-family:Arial;font-size:9.00pt;"&gt;under normal market conditions, the Fund expects it will have an effective duration of approximately 3-9 years.  &lt;/span&gt;&lt;span style="color:#000000;font-family:Arial;font-size:9.00pt;margin-left:0%;"&gt;Under normal market conditions, the Fund will invest at least 50% of its net assets in Municipal Securities that are, at the time of investment, rated investment grade (&lt;/span&gt;&lt;span style="color:#000000;font-family:Arial;font-size:9.00pt;font-style:italic;"&gt;i.e.&lt;/span&gt;&lt;span style="color:#000000;font-family:Arial;font-size:9.00pt;"&gt;, rated Baa3/BBB- or above) by at least one nationally recognized statistical &lt;/span&gt;&lt;span style="color:#000000;font-family:Arial;font-size:9.00pt;margin-left:0%;"&gt;rating organization rating such securities (or Municipal Securities that are unrated and determined by the Fund&#x2019;s advisor to be of comparable quality). If, subsequent to purchase by the Fund, a Municipal Security held by the Fund experiences a decrease in credit quality and is no longer an investment grade Municipal Security, the Fund may continue to hold the Municipal Security and it will not cause the Fund to violate the 50% investment grade requirement; however, the Municipal Security will be taken into account for purposes of determining whether purchases of additional Municipal Securities will cause the Fund to violate such requirement. The Fund will consider pre-refunded or escrowed to maturity bonds, regardless of rating, to be investment &lt;/span&gt;&lt;span style="color:#000000;font-family:Arial;font-size:9.00pt;"&gt;grade Municipal Securities.  &lt;/span&gt;&lt;span style="color:#000000;font-family:Arial;font-size:9.00pt;margin-left:0%;"&gt;Under normal market conditions, the Fund will invest no more than 50% of its net assets in Municipal Securities that are, at the time of investment, not investment grade, commonly referred to as &#x201c;high yield&#x201d; or &#x201c;junk&#x201d; bonds.

If, subsequent to purchase by the Fund, a Municipal Security held by the Fund becomes a Distressed Municipal Security, the Fund may continue to hold the Distressed Municipal Security and it will not cause the Fund to violate the 10% investment limitation; however, the Distressed Municipal Security will be taken into account for purposes of determining whether purchases of additional Municipal Securities will cause the Fund to violate such limitation. &lt;/span&gt;&lt;span style="color:#000000;font-family:Arial;font-size:9.00pt;"&gt;The Fund may also invest in derivatives instruments (including futures contracts).  &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 (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;</rr:StrategyNarrativeTextBlock>

As a means to fight inflation, which remains at elevated levels, the Federal Reserve and certain foreign central banks have raised interest rates&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;line-height:10.80pt;"&gt;  &lt;/span&gt;&lt;span style="font-family:Arial;font-size:9.00pt;"&gt;however, the Federal Reserve has recently lowered interest rates and may continue to do so.

Recent and potential future bank failures could result in disruption to the broader banking industry or markets generally and reduce confidence in financial institutions and the economy as a whole, which may also heighten market volatility and reduce liquidity. &lt;/span&gt;&lt;span style="font-family:Arial;font-size:9.00pt;"&gt;Additionally, challenges in commercial real estate &lt;/span&gt;&lt;span style="font-family:Arial;font-size:9.00pt;margin-left:0%;"&gt;markets, including rising interest rates, declining valuations and increasing vacancies, could have a broader impact on financial markets.&lt;/span&gt;&lt;span style="font-family:Arial;font-size:9.00pt;"&gt; The ongoing adversarial political climate in the United States, as well as political and diplomatic events both domestic &lt;/span&gt;&lt;span style="font-family:Arial;font-size:9.00pt;margin-left:0%;"&gt;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. &lt;/span&gt;&lt;span style="font-family:Arial;font-size:9.00pt;"&gt;The change in administration resulting from &lt;/span&gt;&lt;span style="font-family:Arial;font-size:9.00pt;margin-left:0%;"&gt;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.&lt;/span&gt;&lt;span style="font-family:Arial;font-size:9.00pt;"&gt; Other unexpected political, regulatory and diplomatic events within the &lt;/span&gt;&lt;span style="font-family:Arial;font-size:9.00pt;margin-left:0%;"&gt;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, &lt;/span&gt;&lt;span style="font-family:Arial;font-size:9.00pt;"&gt;Iran, Hamas and &lt;/span&gt;&lt;span style="font-family:Arial;font-size:9.00pt;margin-left:0%;"&gt;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 and other matters. For example, the United States has imposed trade barriers and restrictions 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. &lt;/span&gt;&lt;span style="font-family:Arial;font-size:9.00pt;"&gt;A public health crisis and the ensuing &lt;/span&gt;&lt;span style="font-family:Arial;font-size:9.00pt;margin-left:0%;"&gt;policies enacted by governments and central banks &lt;/span&gt;&lt;span style="font-family:Arial;font-size:9.00pt;"&gt;may cause significant volatility and uncertainty in global financial markets, &lt;/span&gt;&lt;span style="font-family:Arial;font-size:9.00pt;margin-left:0%;"&gt;negatively impacting global growth prospects. &lt;/span&gt;&lt;span style="font-family:Arial;font-size:9.00pt;"&gt;As the COVID-19 global pandemic illustrated, such events may affect certain &lt;/span&gt;&lt;span style="font-family:Arial;font-size:9.00pt;margin-left:0%;"&gt;geographic regions, countries, sectors and industries more significantly than others.

A breach in cyber &lt;/span&gt;&lt;span style="color:#000000;font-family:Arial;font-size:9.00pt;margin-left:0%;"&gt;security refers to both intentional and unintentional events that may cause the Fund to lose proprietary information, suffer data corruption or lose operational capacity. Such events could cause the Fund to incur regulatory penalties, reputational damage, 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. In addition, 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, can also subject the Fund to many of the same risks associated with direct cyber security breaches. Although the Fund has established risk management systems designed to reduce the risks associated with cyber security, 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 &lt;/span&gt;&lt;span style="color:#000000;font-family:Arial;font-size:9.00pt;"&gt;providers.&lt;/span&gt;</rr:RiskTextBlock>

Credit risk refers to &lt;/span&gt;&lt;span style="color:#000000;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 &lt;/span&gt;&lt;span style="color:#000000;font-family:Arial;font-size:9.00pt;"&gt;more difficult to value than common stock.&lt;/span&gt;</rr:RiskTextBlock>

Derivative prices are highly volatile and may fluctuate substantially during a short period of time. &lt;/span&gt;&lt;span style="font-family:Arial;font-size:9.00pt;margin-left:0%;"&gt;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="font-family:Arial;font-size:9.00pt;"&gt;effects of market volatility on share price.&lt;/span&gt;</rr:RiskTextBlock>

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 &lt;/span&gt;&lt;span style="color:#000000;font-family:Arial;font-size:9.00pt;margin-left:0%;"&gt;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;</rr: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. In addition, local, regional or global events such as war, acts of terrorism, market manipulation, government defaults, government shutdowns, regulatory actions, political changes, diplomatic developments, the imposition of sanctions and other similar measures, spread of infectious diseases or other public health issues, recessions, natural disasters, or other events could have a significant negative impact on the Fund and its investments. Any of such circumstances could have a materially negative impact on the value of the Fund&#x2019;s shares, the liquidity of an investment, and may result in increased market volatility. During any such events, the Fund&#x2019;s shares may trade at increased premiums or discounts to their net asset value, the bid/ask spread on the Fund&#x2019;s shares may widen and the returns on investment may &lt;/span&gt;&lt;span style="color:#000000;font-family:Arial;font-size:9.00pt;"&gt;fluctuate.&lt;/span&gt;</rr:RiskTextBlock>

Any reduction in market making capacity has the potential to decrease the Fund&#x2019;s ability to buy or sell municipal securities, and increase price volatility and trading costs, particularly during periods of economic or market stress. As a result, the Fund may be forced to accept a lower price to sell a municipal security, to sell other securities to raise cash, or to give up an investment opportunity, any of which could &lt;/span&gt;&lt;span style="color:#000000;font-family:Arial;font-size:9.00pt;"&gt;have a negative effect on performance.&lt;/span&gt;</rr: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 full impact of the COVID-19 pandemic on state and political subdivisions&#x2019; ability to make payments on debt obligations is impossible to predict, but could negatively impact the value of bonds, the ability of state and political subdivisions to make payments when due and the performance of the Fund. Municipal securities issued by U.S. territories, including, but not limited to, Puerto Rico, the U.S. Virgin Islands and Guam, may face a heightened risk of default due to adverse economic conditions in such territories, which could negatively impact &lt;/span&gt;&lt;span style="color:#000000;font-family:Arial;font-size:9.00pt;"&gt;the value of any Fund investments in U.S. territorial issuers and the Fund&#x2019;s investment performance.&lt;/span&gt;</rr: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;</rr: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;</rr:RiskTextBlock>

Municipal Securities are generally issued by or on behalf of states, territories or &lt;/span&gt;&lt;span style="color:#000000;font-family:Arial;font-size:9.00pt;margin-left:0%;"&gt;possessions of the U.S. and the District of Columbia and their political subdivisions, agencies, authorities and other instrumentalities. The Fund&#x2019;s investment advisor seeks to construct a portfolio that has a weighted average duration of 1&lt;/span&gt;&lt;span style="color:#000000;font-family:Arial;font-size:9.00pt;margin-left:2.5pt;"&gt;&#x2013;3 &lt;/span&gt;&lt;span style="color:#000000;font-family:Arial;font-size:9.00pt;margin-left:0%;"&gt;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 a portfolio of mortgage loans 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. As the value of a security changes over time, so will its duration. The Fund&#x2019;s investment advisor will calculate the duration of the portfolio by modeling the cash flows of all the individual holdings, including the impact of prepayment variability and coupon adjustments where applicable, to determine the duration of each holding and then aggregating based on the size of the position. In performing this duration calculation, &lt;/span&gt;&lt;span style="color:#000000;font-family:Arial;font-size:9.00pt;"&gt;the Fund&#x2019;s investment advisor will utilize third-party models.  &lt;/span&gt;&lt;span style="color:#000000;font-family:Arial;font-size:9.00pt;margin-left:0%;"&gt;In selecting the Fund&#x2019;s portfolio, the portfolio managers will focus on Municipal Securities that meet basic infrastructure needs or provide critical services within their communities. The Fund will invest in Municipal Securities issued throughout the United States, including in Municipal Securities issued by entities in at least 10 different states, with an emphasis on states with growing &lt;/span&gt;&lt;span style="color:#000000;font-family:Arial;font-size:9.00pt;"&gt;populations and healthy employment trends.&lt;/span&gt;&lt;span style="color:#000000;font-family:Arial;font-size:9.00pt;margin-left:0%;"&gt;Under normal market conditions, the Fund will primarily invest in Municipal Securities that are, at the time of investment, rated as investment grade (&lt;/span&gt;&lt;span style="color:#000000;font-family:Arial;font-size:9.00pt;font-style:italic;"&gt;i.e.&lt;/span&gt;&lt;span style="color:#000000;font-family:Arial;font-size:9.00pt;"&gt;, rated Baa3/BBB- or above) by at least one nationally recognized statistical rating organization &lt;/span&gt;&lt;span style="color:#000000;font-family:Arial;font-size:9.00pt;margin-left:0%;"&gt;rating such securities or, if unrated, Municipal Securities determined by the Fund&#x2019;s investment advisor to be of comparable quality. The Fund may invest up to 35% of its net assets in Municipal Securities rated below investment grade by at least one nationally recognized statistical rating organization rating such securities (or Municipal Securities that are unrated and determined by the Fund&#x2019;s investment advisor to be of comparable quality), commonly referred to as &#x201c;high yield&#x201d; or &#x201c;junk&#x201d; &lt;/span&gt;&lt;span style="color:#000000;font-family:Arial;font-size:9.00pt;"&gt;bonds.  &lt;/span&gt;&lt;span style="color:#000000;font-family:Arial;font-size:9.00pt;margin-left:0%;"&gt;The types of Municipal Securities in which the Fund may invest as a part of its principal investment strategy include municipal general obligation bonds, municipal revenue bonds, alternative minimum tax bonds and private activity bonds (including without limitation industrial development bonds), and pre-refunded and escrowed to maturity bonds. Interest on alternative minimum tax bonds and private activity bonds may be subject to the federal alternative minimum tax on individuals. For tax years beginning after December 31, 2022, interest on the bonds may affect the corporate alternative minimum tax for certain &lt;/span&gt;&lt;span style="color:#000000;font-family:Arial;font-size:9.00pt;"&gt;corporations.  &lt;/span&gt;&lt;span style="color:#000000;font-family:Arial;font-size:9.00pt;margin-left:0%;"&gt;The Fund may also purchase new issues of Municipal Securities on a when-issued or forward commitment basis.

Recent and potential future bank failures could result in disruption to the broader banking industry or markets generally and reduce confidence in financial institutions and the economy as a whole, which may also heighten market volatility and reduce liquidity. &lt;/span&gt;&lt;span style="font-family:Arial;font-size:9.00pt;"&gt;Additionally, challenges in commercial real estate &lt;/span&gt;&lt;span style="font-family:Arial;font-size:9.00pt;margin-left:0%;"&gt;markets, including rising interest rates, declining valuations and increasing vacancies, could have a broader impact on financial markets.&lt;/span&gt;&lt;span style="font-family:Arial;font-size:9.00pt;"&gt; The ongoing adversarial political climate in the United States, as well as political and diplomatic events both domestic &lt;/span&gt;&lt;span style="font-family:Arial;font-size:9.00pt;margin-left:0%;"&gt;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. &lt;/span&gt;&lt;span style="font-family:Arial;font-size:9.00pt;"&gt;The change in administration resulting from &lt;/span&gt;&lt;span style="font-family:Arial;font-size:9.00pt;margin-left:0%;"&gt;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.&lt;/span&gt;&lt;span style="font-family:Arial;font-size:9.00pt;"&gt; Other unexpected political, regulatory and diplomatic events within the &lt;/span&gt;&lt;span style="font-family:Arial;font-size:9.00pt;margin-left:0%;"&gt;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, &lt;/span&gt;&lt;span style="font-family:Arial;font-size:9.00pt;"&gt;Iran, Hamas and &lt;/span&gt;&lt;span style="font-family:Arial;font-size:9.00pt;margin-left:0%;"&gt;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 and other matters. For example, the United States has imposed trade barriers and restrictions on China. In addition, the Chinese government is engaged in a longstanding dispute with Taiwan, continually threatening an invasion.

A breach in cyber &lt;/span&gt;&lt;span style="color:#000000;font-family:Arial;font-size:9.00pt;margin-left:0%;"&gt;security refers to both intentional and unintentional events that may cause the Fund to lose proprietary information, suffer data corruption or lose operational capacity. Such events could cause the Fund to incur regulatory penalties, reputational damage, 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. In addition, 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, can also subject the Fund to many of the same risks associated with direct cyber security breaches. Although the Fund has established risk &lt;/span&gt;&lt;span style="color:#000000;font-family:Arial;font-size:9.00pt;margin-left:0%;"&gt;management systems designed to reduce the risks associated with cyber security, 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 &lt;/span&gt;&lt;span style="color:#000000;font-family:Arial;font-size:9.00pt;"&gt;providers.&lt;/span&gt;</rr:RiskTextBlock>

Credit risk refers to &lt;/span&gt;&lt;span style="color:#000000;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 &lt;/span&gt;&lt;span style="color:#000000;font-family:Arial;font-size:9.00pt;"&gt;more difficult to value than common stock.&lt;/span&gt;</rr:RiskTextBlock>

Rising interest rates tend to extend the duration of debt securities, making their market value more sensitive to changes in interest rates.

Floating rate debt instruments include debt securities issued by corporate and governmental entities, as well as bank loans, mortgage-backed securities and asset-backed securities. Floating rate debt instruments are structured so that the security&#x2019;s coupon rate fluctuates based upon the level of a reference rate. Most commonly, the coupon rate of a floating rate debt instrument is set at the level of a widely followed interest rate, plus a fixed spread. As a result, the coupon on floating rate debt instrument will generally decline in a falling interest rate environment, causing the Fund to experience a reduction in the income it receives from the instrument. A floating rate debt instrument&#x2019;s coupon rate resets periodically according to its terms. Consequently, in a rising interest rate environment, floating rate debt instruments with coupon rates that reset infrequently may lag behind the changes in market interest rates. Floating rate debt instruments may also contain terms that impose a maximum coupon rate the issuer will pay, regardless of the level of the reference rate. To the extent the Fund invests in floating rate loans, such instruments may be subject to legal or contractual restrictions on resale, may trade infrequently, and their value may be impaired when the Fund needs to liquidate such securities. It is possible that the collateral securing a floating rate loan may be insufficient or unavailable to the Fund, and that the Fund&#x2019;s rights to collateral may be limited by bankruptcy or insolvency laws. Additionally, floating rate loans may not be considered &#x201c;securities&#x201d; under federal securities laws, and purchasers, such as the Fund, therefore may not be entitled to rely on the anti-fraud protections of the federal &lt;/span&gt;&lt;span style="color:#000000;font-family:Arial;font-size:9.00pt;"&gt;securities laws.&lt;/span&gt;</rr: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;</rr: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 &lt;/span&gt;&lt;span style="color:#000000;font-family:Arial;font-size:9.00pt;margin-left:0%;"&gt;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 full impact of the COVID-19 pandemic on state and political subdivisions&#x2019; ability to make payments on debt obligations is impossible to predict, but could negatively impact the value of bonds, the ability of state and political subdivisions to make payments when due and the performance of the Fund. Municipal securities issued by U.S. territories, including, but not limited to, Puerto Rico, the U.S. Virgin Islands and Guam, may face a heightened risk of default due to adverse economic conditions in such territories, which could negatively impact &lt;/span&gt;&lt;span style="color:#000000;font-family:Arial;font-size:9.00pt;"&gt;the value of any Fund investments in U.S. territorial issuers and the Fund&#x2019;s investment performance.&lt;/span&gt;</rr: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;</rr: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;</rr:RiskTextBlock>

In such a transaction, the purchase price of the &lt;/span&gt;&lt;span style="color:#000000;font-family:Arial;font-size:9.00pt;margin-left:0%;"&gt;securities is typically fixed at the time of the commitment, but delivery and payment can take place a month or more after the date of the commitment. At the time of delivery of the securities, the value may be more or less than the purchase or sale price. Purchasing securities on a when-issued, TBA, delayed delivery or forward commitment basis may give rise to investment leverage and may increase the Fund&#x2019;s volatility. Default by, or bankruptcy of, a counterparty to a when-issued, TBA, delayed delivery or forward commitment transaction would expose the Fund to possible losses because of an adverse market action, &lt;/span&gt;&lt;span style="color:#000000;font-family:Arial;font-size:9.00pt;"&gt;expenses or delays in connection with the purchase or sale of the pools specified in such transaction.&lt;/span&gt;</rr:RiskTextBlock>

Under normal market conditions, the weighted average duration of the Fund&#x2019;s portfolio is expected to be less than one year. &lt;/span&gt;&lt;span style="color:#000000;font-family:Arial;font-size:9.00pt;"&gt;In selecting the Fund&#x2019;s portfolio, the portfolio managers will focus on Municipal Securities that meet basic &lt;/span&gt;&lt;span style="color:#000000;font-family:Arial;font-size:9.00pt;margin-left:0%;"&gt;infrastructure needs or provide critical services within their communities. The Fund will invest in Municipal Securities issued throughout the United States, including in Municipal Securities issued by entities in at least 10 different states, with an emphasis &lt;/span&gt;&lt;span style="color:#000000;font-family:Arial;font-size:9.00pt;"&gt;on Municipal Securities issued in states with growing populations and healthy employment trends.&lt;/span&gt;&lt;span style="color:#000000;font-family:Arial;font-size:9.00pt;margin-left:0%;"&gt;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 a portfolio of Municipal Securities 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 &lt;/span&gt;&lt;span style="color:#000000;font-family:Arial;font-size:9.00pt;margin-left:0%;"&gt;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. As the value of a security changes over time, so will &lt;/span&gt;&lt;span style="color:#000000;font-family:Arial;font-size:9.00pt;"&gt;its duration.  &lt;/span&gt;&lt;span style="color:#000000;font-family:Arial;font-size:9.00pt;margin-left:0%;"&gt;Under normal market conditions, the Fund will invest at least 80% of its net assets in Municipal Securities that are, at the time of investment, rated as investment grade (&lt;/span&gt;&lt;span style="color:#000000;font-family:Arial;font-size:9.00pt;font-style:italic;"&gt;i.e.&lt;/span&gt;&lt;span style="color:#000000;font-family:Arial;font-size:9.00pt;"&gt;, rated Baa3/BBB- or above) by at least one nationally recognized statistical &lt;/span&gt;&lt;span style="color:#000000;font-family:Arial;font-size:9.00pt;margin-left:0%;"&gt;rating organization rating such securities or, if unrated, Municipal Securities determined by the Fund&#x2019;s investment advisor to be of comparable quality.

As a means to fight inflation, which remains at elevated levels, the Federal Reserve and certain foreign central banks have raised interest rates&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;line-height:10.80pt;"&gt;  &lt;/span&gt;&lt;span style="font-family:Arial;font-size:9.00pt;"&gt;however, the Federal Reserve has recently lowered interest rates and may continue to do so. U.S. regulators have proposed several changes to market and issuer &lt;/span&gt;&lt;span style="font-family:Arial;font-size:9.00pt;margin-left:0%;"&gt;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. Recent and potential future bank failures could result in disruption to the broader banking industry or markets generally and reduce confidence in financial institutions and the economy as a whole, which may also heighten market volatility and reduce liquidity. &lt;/span&gt;&lt;span style="font-family:Arial;font-size:9.00pt;"&gt;Additionally, challenges in commercial real estate &lt;/span&gt;&lt;span style="font-family:Arial;font-size:9.00pt;margin-left:0%;"&gt;markets, including rising interest rates, declining valuations and increasing vacancies, could have a broader impact on financial markets.&lt;/span&gt;&lt;span style="font-family:Arial;font-size:9.00pt;"&gt; The ongoing adversarial political climate in the United States, as well as political and diplomatic events both domestic &lt;/span&gt;&lt;span style="font-family:Arial;font-size:9.00pt;margin-left:0%;"&gt;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. &lt;/span&gt;&lt;span style="font-family:Arial;font-size:9.00pt;"&gt;The change in administration resulting from &lt;/span&gt;&lt;span style="font-family:Arial;font-size:9.00pt;margin-left:0%;"&gt;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.&lt;/span&gt;&lt;span style="font-family:Arial;font-size:9.00pt;"&gt; Other unexpected political, regulatory and diplomatic events within the &lt;/span&gt;&lt;span style="font-family:Arial;font-size:9.00pt;margin-left:0%;"&gt;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, &lt;/span&gt;&lt;span style="font-family:Arial;font-size:9.00pt;"&gt;Iran, Hamas and &lt;/span&gt;&lt;span style="font-family:Arial;font-size:9.00pt;margin-left:0%;"&gt;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 and other matters. For example, the United States has imposed trade barriers and restrictions 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. &lt;/span&gt;&lt;span style="font-family:Arial;font-size:9.00pt;"&gt;A public health crisis and the ensuing &lt;/span&gt;&lt;span style="font-family:Arial;font-size:9.00pt;margin-left:0%;"&gt;policies enacted by governments and central banks &lt;/span&gt;&lt;span style="font-family:Arial;font-size:9.00pt;"&gt;may cause significant volatility and uncertainty in global financial markets, &lt;/span&gt;&lt;span style="font-family:Arial;font-size:9.00pt;margin-left:0%;"&gt;negatively impacting global growth prospects. &lt;/span&gt;&lt;span style="font-family:Arial;font-size:9.00pt;"&gt;As the COVID-19 global pandemic illustrated, such events may affect certain &lt;/span&gt;&lt;span style="font-family:Arial;font-size:9.00pt;margin-left:0%;"&gt;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. &lt;/span&gt;&lt;span style="font-family:Arial;font-size:9.00pt;"&gt;Additionally, cyber security breaches of both &lt;/span&gt;&lt;span style="font-family:Arial;font-size:9.00pt;margin-left:0%;"&gt;government and non-government entities could have negative impacts on infrastructure and the ability of such entities, including the Fund, to operate properly.&lt;/span&gt;&lt;span style="font-family:Arial;font-size:9.00pt;"&gt; These events, and any other future events, may adversely affect the prices and liquidity of the Fund&#x2019;s portfolio investments and could result in disruptions in the trading markets.&lt;/span&gt;</rr:RiskTextBlock>

A breach in cyber &lt;/span&gt;&lt;span style="color:#000000;font-family:Arial;font-size:9.00pt;margin-left:0%;"&gt;security refers to both intentional and unintentional events that may cause the Fund to lose proprietary information, suffer data corruption or lose operational capacity. Such events could cause the Fund to incur regulatory penalties, reputational damage, 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. In addition, 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, can also subject the Fund to many of the same risks associated with direct cyber security breaches. Although the Fund has established risk management systems designed to reduce the risks associated with cyber security, 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 &lt;/span&gt;&lt;span style="color:#000000;font-family:Arial;font-size:9.00pt;"&gt;providers.&lt;/span&gt;</rr:RiskTextBlock>

Credit risk refers to &lt;/span&gt;&lt;span style="color:#000000;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 &lt;/span&gt;&lt;span style="color:#000000;font-family:Arial;font-size:9.00pt;"&gt;more difficult to value than common stock.&lt;/span&gt;</rr:RiskTextBlock>

Rising interest rates tend to extend the duration of debt securities, making their market value more sensitive to changes in interest rates.

Floating rate debt instruments include debt securities issued by corporate and governmental entities, as well as bank loans, mortgage-backed securities and asset-backed securities. Floating rate debt instruments are structured so that the security&#x2019;s coupon rate fluctuates based upon the level of a reference rate. Most commonly, the coupon rate of a floating rate debt instrument is set at the level of a widely followed interest rate, plus a fixed spread. As a result, the coupon on floating rate debt instrument will generally decline in a falling interest rate environment, causing the Fund to experience a reduction in the income it receives from the instrument. A floating rate debt instrument&#x2019;s coupon rate resets periodically according to its terms. Consequently, in a rising interest rate environment, floating rate debt instruments with coupon rates that reset infrequently may lag behind the changes in market interest rates. Floating rate debt instruments may also contain terms that impose a maximum coupon rate the issuer will pay, regardless of the level of the reference rate. To the extent the Fund invests in floating rate loans, such instruments may be subject to legal or contractual restrictions on resale, may trade infrequently, and their value may be impaired when the Fund needs to liquidate such securities. It is possible that the collateral securing a floating rate loan may be insufficient or unavailable to the Fund, and that the Fund&#x2019;s rights to collateral may be limited by bankruptcy or insolvency laws. Additionally, floating rate loans may not be considered &#x201c;securities&#x201d; under federal securities laws, and purchasers, such as the Fund, therefore may not be entitled to rely on the anti-fraud protections of the federal &lt;/span&gt;&lt;span style="color:#000000;font-family:Arial;font-size:9.00pt;"&gt;securities laws.&lt;/span&gt;</rr: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;</rr:RiskTextBlock>

Decisions by market makers or authorized participants to reduce their 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="color:#000000;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;</rr:RiskTextBlock>

Shares of the Fund could decline in value or underperform other investments.

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 &lt;/span&gt;&lt;span style="color:#000000;font-family:Arial;font-size:9.00pt;margin-left:0%;"&gt;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 full impact of the COVID-19 pandemic on state and political subdivisions&#x2019; ability to make payments on debt obligations is impossible to predict, but could negatively impact the value of bonds, the ability of state and political subdivisions to make payments when due and the performance of the Fund. Municipal securities issued by U.S. territories, including, but not limited to, Puerto Rico, the U.S. Virgin Islands and Guam, may face a heightened risk of default due to adverse economic conditions in such territories, which could negatively impact &lt;/span&gt;&lt;span style="color:#000000;font-family:Arial;font-size:9.00pt;"&gt;the value of any Fund investments in U.S. territorial issuers and the Fund&#x2019;s investment performance.&lt;/span&gt;</rr: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;</rr:RiskTextBlock>

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;</rr:RiskTextBlock>

In such a transaction, the purchase price of the securities is typically fixed at the time of the commitment, but delivery and payment can take place &lt;/span&gt;&lt;span style="font-family:Arial;font-size:9.00pt;"&gt;some time after the date of the commitment. At the time of &lt;/span&gt;&lt;span style="font-family:Arial;font-size:9.00pt;margin-left:0%;"&gt;delivery of the securities, the value may be more or less than the purchase or sale price. Purchasing securities on a when-issued, &lt;/span&gt;&lt;span style="font-family:Arial;font-size:9.00pt;"&gt;delayed delivery or forward commitment basis may give rise to investment leverage and may increase the Fund&#x2019;s volatility. &lt;/span&gt;&lt;span style="font-family:Arial;font-size:9.00pt;margin-left:0%;"&gt;Default by, or bankruptcy of, a counterparty to a when-issued, &lt;/span&gt;&lt;span style="font-family:Arial;font-size:9.00pt;"&gt;delayed delivery or forward commitment transaction would &lt;/span&gt;&lt;span style="font-family:Arial;font-size:9.00pt;margin-left:0%;"&gt;expose the Fund to possible losses because of an adverse market action, expenses or delays in connection with the purchase &lt;/span&gt;&lt;span style="font-family:Arial;font-size:9.00pt;"&gt;or sale of the pools specified in such transaction.&lt;/span&gt;</rr:RiskTextBlock>

Indexes do not charge management fees or brokerage expenses, and no such fees or expenses were deducted from the index performance shown. Indexes are unmanaged and an investor cannot invest directly in an index. The Blended Benchmark returns are calculated by using the monthly return of the two indices during each period shown above. At the beginning of each month the two indices are rebalanced to a 50-50 ratio to account for divergence from that ratio that occurred during the course of each month. The monthly returns are then compounded for each period shown above, giving the performance for the Blended Benchmark for each period shown above.</xhtml:span></link:footnote>
