Municipal bonds are obligations issued by or on behalf of states, territories and possessions of the United States &lt;/span&gt;&lt;span style="clear:both;font-family:Arial, Helvetica, sans-serif;font-size:8.02pt;;"&gt;(including the District of Columbia, Puerto Rico, the U.S. Virgin Islands, and Guam), their political subdivisions - such as cities and counties - and their agencies &lt;/span&gt;&lt;span style="clear:both;font-family:Arial, Helvetica, sans-serif;font-size:8.02pt;;"&gt;or authorities to finance public-purpose projects. All investments in the Fund are denominated in U.S. dollars. The interest on municipal bonds is excludable &lt;/span&gt;&lt;span style="clear:both;font-family:Arial, Helvetica, sans-serif;font-size:8.02pt;;"&gt;from gross income for federal income tax purposes, although a significant portion of such interest may be a tax-preference item for purposes of the federal &lt;/span&gt;&lt;span style="clear:both;font-family:Arial, Helvetica, sans-serif;font-size:8.02pt;;"&gt;alternative minimum tax (the &#x201c;AMT&#x201d;) applicable to noncorporate taxpayers.&lt;/span&gt;&lt;span style="clear:both;font-family:Arial, Helvetica, sans-serif;font-size:8.02pt;;"&gt; Municipal bonds subject to AMT are considered tax-exempt municipal bonds for &lt;/span&gt;&lt;span style="clear:both;font-family:Arial, Helvetica, sans-serif;font-size:8.02pt;;"&gt;purposes of the Fund&#x2019;s 80% policy.&lt;/span&gt;&lt;/div&gt;&lt;div&gt;&lt;span style="clear:both;font-family:Arial, Helvetica, sans-serif;font-size:8.02pt;;"&gt;The Fund typically invests in medium- and lower-quality bonds rated BBB+ or lower by S&amp;amp;P Global Ratings (&#x201c;S&amp;amp;P&#x201d;), comparably rated by another nationally &lt;/span&gt;&lt;span style="clear:both;font-family:Arial, Helvetica, sans-serif;font-size:8.02pt;;"&gt;recognized statistical rating organization (&#x201c;NRSRO&#x201d;), or, if unrated, determined by abrdn Inc.

If a bond is rated differently among &lt;/span&gt;&lt;span style="clear:both;font-family:Arial, Helvetica, sans-serif;font-size:8.02pt;;"&gt;NRSROs (commonly referred to as &lt;/span&gt;&lt;span style="clear:both;font-family:Arial, Helvetica, sans-serif;font-size:8.02pt;;"&gt;&#x201d;split-rated&#x201d;), the sub-advisor can consider the bond to have the higher credit rating. The Fund may invest an unlimited &lt;/span&gt;&lt;span style="clear:both;font-family:Arial, Helvetica, sans-serif;font-size:8.02pt;;"&gt;amount of its total assets in non-investment-grade debt securities. Although the sub-advisor considers credit ratings in selecting investments for the Fund, it &lt;/span&gt;&lt;span style="clear:both;font-family:Arial, Helvetica, sans-serif;font-size:8.02pt;;"&gt;makes investment decisions based on its own credit analysis rather than an NRSRO&#x2019;s credit rating. In making such evaluations, the sub-advisor considers, &lt;/span&gt;&lt;span style="clear:both;font-family:Arial, Helvetica, sans-serif;font-size:8.02pt;;"&gt;among other attributes, the issuer&#x2019;s financial resources and operating history; its sensitivity to economic conditions and trends; its debt maturity schedules and &lt;/span&gt;&lt;span style="clear:both;font-family:Arial, Helvetica, sans-serif;font-size:8.02pt;;"&gt;borrowing requirements; and the relative value of the investment based on anticipated cash flows, interest- and asset-coverage metrics.&lt;/span&gt;&lt;span style="clear:both;font-family:Arial, Helvetica, sans-serif;font-size:8.02pt;;"&gt; To a lesser extent, the &lt;/span&gt;&lt;span style="clear:both;font-family:Arial, Helvetica, sans-serif;font-size:8.02pt;;"&gt;Fund may also invest in higher-quality municipal bonds when yield spreads are narrow and the sub-advisor believes that the higher yields available in &lt;/span&gt;&lt;span style="clear:both;font-family:Arial, Helvetica, sans-serif;font-size:8.02pt;;"&gt;lower-quality bonds do not compensate for the increased risk, or when, in the opinion of the sub-advisor, there is a lack of medium- and lower-quality bonds &lt;/span&gt;&lt;span style="clear:both;font-family:Arial, Helvetica, sans-serif;font-size:8.02pt;;"&gt;in which to&#160;&#x2009;invest.&lt;/span&gt;&lt;/div&gt;&lt;div&gt;&lt;span style="clear:both;font-family:Arial, Helvetica, sans-serif;font-size:8.02pt;;"&gt;The sub-advisor determines the desired duration and maturity profile of the Fund&#x2019;s holdings based on its view of interest rates. The Fund may invest in &lt;/span&gt;&lt;span style="clear:both;font-family:Arial, Helvetica, sans-serif;font-size:8.02pt;;"&gt;instruments of any maturity, although it will generally seek instruments with remaining&#160;&#x2009;maturities of 5 to 30 years.&lt;/span&gt;&lt;/div&gt;&lt;div&gt;&lt;span style="clear:both;font-family:Arial, Helvetica, sans-serif;font-size:8.02pt;;"&gt;In selecting investments for the Fund, the sub-advisor begins with top-down macro themes, including sector outlook, geographic strength, economic &lt;/span&gt;&lt;span style="clear:both;font-family:Arial, Helvetica, sans-serif;font-size:8.02pt;;"&gt;conditions, interest rate expectations, and credit spread dynamics. Within these macro views, the sub-advisor seeks to capture a broad range of credit &lt;/span&gt;&lt;span style="clear:both;font-family:Arial, Helvetica, sans-serif;font-size:8.02pt;;"&gt;opportunities through bottom-up fundamental research, evaluating factors such as debt profile, liquidity, profitability, management quality, security and &lt;/span&gt;&lt;span style="clear:both;font-family:Arial, Helvetica, sans-serif;font-size:8.02pt;;"&gt;covenant protections, and socioeconomic trends, among other factors. The sub-advisor generally emphasizes yield-oriented opportunities to help maximize &lt;/span&gt;&lt;span style="clear:both;font-family:Arial, Helvetica, sans-serif;font-size:8.02pt;;"&gt;the Fund&#x2019;s tax efficiency and minimize taxable capital gains. In constructing the portfolio, the sub-advisor also monitors state- and sector-level exposures and &lt;/span&gt;&lt;span style="clear:both;font-family:Arial, Helvetica, sans-serif;font-size:8.02pt;;"&gt;single issuer allocations as it seeks to manage concentration risk and maintain diversification.&lt;/span&gt;&lt;span style="clear:both;font-family:Arial, Helvetica, sans-serif;font-size:8.02pt;;"&gt; The Fund does not expect to concentrate its investments in any &lt;/span&gt;&lt;span style="clear:both;font-family:Arial, Helvetica, sans-serif;font-size:8.02pt;;"&gt;single state, territory, possession or industry.&lt;/span&gt;&lt;/div&gt;&lt;div&gt;&lt;span style="clear:both;font-family:Arial, Helvetica, sans-serif;font-size:8.02pt;;"&gt;Municipal bonds in which the Fund may invest include, but are not limited to, revenue bonds, general obligation bonds, auction rate securities, private activity &lt;/span&gt;&lt;span style="clear:both;font-family:Arial, Helvetica, sans-serif;font-size:8.02pt;;"&gt;bonds (&#x201c;PABs&#x201d;), moral obligation bonds, municipal notes, municipal commercial paper, municipal lease obligations and tender-option bonds.&lt;/span&gt;&lt;/div&gt;&lt;div&gt;&lt;span style="clear:both;font-family:Arial, Helvetica, sans-serif;font-size:8.02pt;;"&gt;Revenue bonds are payable only from specific sources, such as the revenue from a particular project, special taxes, certain lease payments, or other &lt;/span&gt;&lt;span style="clear:both;font-family:Arial, Helvetica, sans-serif;font-size:8.02pt;;"&gt;appropriated funds. Revenue bonds may include private-activity bonds (or &#x201c;PABs&#x201d;) that finance private initiatives, such as housing bonds that finance pools of &lt;/span&gt;&lt;span style="clear:both;font-family:Arial, Helvetica, sans-serif;font-size:8.02pt;;"&gt;single-family mortgages; student-loan bonds that finance student loans; education bonds that finance charter schools; and health care bonds that finance &lt;/span&gt;&lt;span style="clear:both;font-family:Arial, Helvetica, sans-serif;font-size:8.02pt;;"&gt;hospitals and other medical facilities. &lt;/span&gt;&lt;span style="clear:both;font-family:Arial, Helvetica, sans-serif;font-size:8.02pt;;"&gt;Revenue bonds may be issued as commercial paper, notes, lease obligations, or tender-option bonds. A moral obligation &lt;/span&gt;&lt;span style="clear:both;font-family:Arial, Helvetica, sans-serif;font-size:8.02pt;;"&gt;bond is a revenue-backed instrument where a state or municipality &#x201c;morally&#x201d; &#x2013; but not legally &#x2013; pledges to appropriate funds to replenish a debt service &lt;/span&gt;&lt;span style="clear:both;font-family:Arial, Helvetica, sans-serif;font-size:8.02pt;;"&gt;reserve fund if projected revenues fall short. A municipal lease obligation is issued to finance the acquisition of equipment and facilities. A municipal &lt;/span&gt;&lt;span style="clear:both;font-family:Arial, Helvetica, sans-serif;font-size:8.02pt;;"&gt;tender-option bond is a structured product that divides a bond into short-term, floating-rate certificates with a tender option and longer-term, inverse &lt;/span&gt;&lt;span style="clear:both;font-family:Arial, Helvetica, sans-serif;font-size:8.02pt;;"&gt;floating-rate securities. The Fund will invest in tender-option floaters and is not expected to hold inverse floaters. The Fund may have significant exposure to &lt;/span&gt;&lt;span style="clear:both;font-family:Arial, Helvetica, sans-serif;font-size:8.02pt;;"&gt;the Health Care and Education sectors. Health Care includes industries such as hospitals, hospital districts, continuing care retirement communities, nursing &lt;/span&gt;&lt;span style="clear:both;font-family:Arial, Helvetica, sans-serif;font-size:8.02pt;;"&gt;homes, and assisted living, among others. Education includes charter schools, school districts, and higher education facilities, among others. However, as the &lt;/span&gt;&lt;span style="clear:both;font-family:Arial, Helvetica, sans-serif;font-size:8.02pt;;"&gt;sector composition of the Fund&#x2019;s portfolio changes over time, the Fund&#x2019;s exposure to the Health Care and Education sectors may decline, and the Fund&#x2019;s &lt;/span&gt;&lt;span style="clear:both;font-family:Arial, Helvetica, sans-serif;font-size:8.02pt;;"&gt;exposure to other market sectors may increase.&lt;/span&gt;&lt;/div&gt;&lt;div&gt;&lt;span style="clear:both;font-family:Arial, Helvetica, sans-serif;font-size:8.02pt;;"&gt;The debt securities held by the Fund may be in the form of general obligation bonds, debentures, zero-coupon securities, and callable securities. A general &lt;/span&gt;&lt;span style="clear:both;font-family:Arial, Helvetica, sans-serif;font-size:8.02pt;;"&gt;obligation bond is secured by the full faith and credit of its issuer, while a debenture is unsecured. A zero-coupon security does not make periodic interest &lt;/span&gt;&lt;span style="clear:both;font-family:Arial, Helvetica, sans-serif;font-size:8.02pt;;"&gt;payments. A callable security may be redeemed, or called, by the issuer prior to maturity date, ceasing interest payments. The Fund can invest in securities that &lt;/span&gt;&lt;span style="clear:both;font-family:Arial, Helvetica, sans-serif;font-size:8.02pt;;"&gt;are not registered &lt;/span&gt;&lt;span style="clear:both;font-family:Arial, Helvetica, sans-serif;font-size:8.02pt;;"&gt;with the Securities and Exchange Commission and&lt;/span&gt;&lt;span style="clear:both;font-family:Arial, Helvetica, sans-serif;font-size:8.02pt;;"&gt; thus restricted in their ability to be traded.&lt;/span&gt;&lt;/div&gt;&lt;div&gt;&lt;span style="clear:both;font-family:Arial, Helvetica, sans-serif;font-size:8.02pt;;"&gt;In determining whether to sell a security, the sub-advisor uses similar analysis as it employs when purchasing securities. The analysis generally begins with an &lt;/span&gt;&lt;span style="clear:both;font-family:Arial, Helvetica, sans-serif;font-size:8.02pt;;"&gt;outlook on the credit quality and relative value of the instrument followed by&lt;/span&gt;&lt;span style="clear:both;font-family:Arial, Helvetica, sans-serif;font-size:8.02pt;;"&gt;&#160;&#x2009;&lt;/span&gt;&lt;span style="clear:both;font-family:Arial, Helvetica, sans-serif;font-size:8.02pt;;"&gt;macroeconomic and sector-related considerations. Securities may also be sold &lt;/span&gt;&lt;span style="clear:both;font-family:Arial, Helvetica, sans-serif;font-size:8.02pt;;"&gt;to&#x2009;rebalance the Fund&#x2019;s holdings, to take advantage of more attractive investment opportunities, or to raise cash.&lt;/span&gt;&lt;/div&gt;</oef:StrategyNarrativeTextBlock>

Cybersecurity incidents may allow an unauthorized party to gain access to Fund assets, shareholder data, or proprietary information, &lt;/span&gt;&lt;span style="clear:both;font-family:Arial, Helvetica, sans-serif;font-size:8.02pt;;"&gt;or cause the Fund or its service providers, as well as securities trading venues and their service providers, to suffer data corruption or lose operational &lt;/span&gt;&lt;span style="clear:both;font-family:Arial, Helvetica, sans-serif;font-size:8.02pt;;"&gt;functionality. Cybersecurity incidents can result from deliberate attacks or unintentional events. It is not possible for the Fund or its service providers to identify &lt;/span&gt;&lt;span style="clear:both;font-family:Arial, Helvetica, sans-serif;font-size:8.02pt;;"&gt;all of the operational risks that may affect the Fund or to develop processes and controls to completely eliminate or mitigate their occurrence or effects. The &lt;/span&gt;&lt;span style="clear:both;font-family:Arial, Helvetica, sans-serif;font-size:8.02pt;;"&gt;Fund cannot control the cybersecurity and operational plans and systems of its service providers, its counterparties or the issuers of securities in which the &lt;/span&gt;&lt;span style="clear:both;font-family:Arial, Helvetica, sans-serif;font-size:8.02pt;;"&gt;Fund invests. The issuers of the Fund&#x2019;s investments are likely to be dependent on computers for their operations and require ready access to their data and the &lt;/span&gt;&lt;span style="clear:both;font-family:Arial, Helvetica, sans-serif;font-size:8.02pt;;"&gt;internet to conduct their business. Thus, cybersecurity incidents could also affect issuers of the Fund&#x2019;s investments, leading to significant loss of value.&lt;/span&gt;&lt;/div&gt;</oef:RiskTextBlock>

Only an Authorized Participant may transact in Creation Units directly with the Fund, and none of those &lt;/span&gt;&lt;span style="clear:both;font-family:Arial, Helvetica, sans-serif;font-size:8.02pt;;"&gt;Authorized Participants is obligated to engage in creation and/or redemption transactions. To the extent they exit the business or are otherwise unable to &lt;/span&gt;&lt;span style="clear:both;font-family:Arial, Helvetica, sans-serif;font-size:8.02pt;;"&gt;proceed in creation and redemption transactions with the Fund and no other Authorized Participant is able to step forward to create or redeem shares, then &lt;/span&gt;&lt;span style="clear:both;font-family:Arial, Helvetica, sans-serif;font-size:8.02pt;;"&gt;shares of the Fund may be more likely to trade at a premium or discount to net asset value (&#x201c;NAV&#x201d;) and possibly face trading halts or delisting. Authorized &lt;/span&gt;&lt;span style="clear:both;font-family:Arial, Helvetica, sans-serif;font-size:8.02pt;;"&gt;Participant concentration risk may be heightened for ETFs that invest in securities or instruments that have lower trading volumes.&lt;/span&gt;&lt;/div&gt;

Unlike many other ETFs, however, the Fund expects to effect its creations and redemptions at least partially &lt;/span&gt;&lt;span style="clear:both;font-family:Arial, Helvetica, sans-serif;font-size:8.02pt;;"&gt;or fully&lt;/span&gt;&lt;span style="clear:both;font-family:Arial, Helvetica, sans-serif;font-size:8.02pt;;"&gt; for cash, rather than in-kind &lt;/span&gt;&lt;/div&gt;

Thus, an investment in the Fund may be less tax-efficient than an investment in other ETFs as the Fund may recognize a capital gain that it could &lt;/span&gt;&lt;span style="clear:both;font-family:Arial, Helvetica, sans-serif;font-size:8.02pt;;"&gt;have avoided by making redemptions in-kind. As a result, the Fund may pay out higher capital gains distributions than ETFs that redeem in-kind. Further, &lt;/span&gt;&lt;span style="clear:both;font-family:Arial, Helvetica, sans-serif;font-size:8.02pt;;"&gt;paying redemption proceeds in cash rather than through in-kind delivery of portfolio securities may require the Fund to dispose of or sell portfolio &lt;/span&gt;&lt;span style="clear:both;font-family:Arial, Helvetica, sans-serif;font-size:8.02pt;;"&gt;investments to obtain the cash needed to distribute redemption proceeds at an inopportune time.&lt;/span&gt;&lt;/div&gt;

As a result, shareholders of the Fund may pay more than NAV when purchasing shares and receive less than NAV when selling Fund shares. This &lt;/span&gt;&lt;span style="clear:both;font-family:Arial, Helvetica, sans-serif;font-size:8.02pt;;"&gt;risk is heightened in times of market volatility or periods of steep market declines. In such market conditions, market or stop loss orders to sell Fund shares &lt;/span&gt;&lt;span style="clear:both;font-family:Arial, Helvetica, sans-serif;font-size:8.02pt;;"&gt;may be executed at prices well below NAV.&lt;/span&gt;&lt;/div&gt;

In addition, such investors may incur &lt;/span&gt;&lt;span style="clear:both;font-family:Arial, Helvetica, sans-serif;font-size:8.02pt;;"&gt;the cost of the &#x201c;spread&#x201d; also known as the bid-ask spread, which is the difference between what investors are willing to pay for Fund shares (the &#x201c;bid&#x201d; &lt;/span&gt;&lt;span style="clear:both;font-family:Arial, Helvetica, sans-serif;font-size:8.02pt;;"&gt;price) and the price at which they are willing to sell Fund shares (the &#x201c;ask&#x201d; price). The bid-ask spread varies over time based on, among other things, &lt;/span&gt;&lt;span style="clear:both;font-family:Arial, Helvetica, sans-serif;font-size:8.02pt;;"&gt;trading volume, market liquidity and market volatility. Trading in Fund shares may be halted by the Exchange (as defined below) because of market &lt;/span&gt;&lt;span style="clear:both;font-family:Arial, Helvetica, sans-serif;font-size:8.02pt;;"&gt;conditions or other reasons. If a trading halt occurs, a shareholder may temporarily be unable to purchase or sell shares of the Fund. In addition, although &lt;/span&gt;&lt;span style="clear:both;font-family:Arial, Helvetica, sans-serif;font-size:8.02pt;;"&gt;the Fund&#x2019;s shares are listed on the Exchange, there can be no assurance that an active trading market for shares will develop or be maintained or that the &lt;/span&gt;&lt;span style="clear:both;font-family:Arial, Helvetica, sans-serif;font-size:8.02pt;;"&gt;Fund&#x2019;s shares will continue to be listed.&lt;/span&gt;&lt;/div&gt;

High-yield debt securities may fluctuate more widely in price and yield and may fall in price when the economy is &lt;/span&gt;&lt;span style="clear:both;font-family:Arial, Helvetica, sans-serif;font-size:8.02pt;;"&gt;weak or expected to become weak.

Fixed-income securities with longer &lt;/span&gt;&lt;span style="clear:both;font-family:Arial, Helvetica, sans-serif;font-size:8.02pt;;"&gt;durations generally have greater sensitivity to changes in interest rates than those with shorter durations.

For example, if a bond has a &lt;/span&gt;&lt;span style="clear:both;font-family:Arial, Helvetica, sans-serif;font-size:8.02pt;;"&gt;duration of 8 years, a 1% increase in interest rates could be expected to result in an 8% decrease in the value of the bond.

An inability to sell a portfolio position can adversely affect the Fund&#x2019;s value or prevent the Fund from being able to take &lt;/span&gt;&lt;span style="clear:both;font-family:Arial, Helvetica, sans-serif;font-size:8.02pt;;"&gt;advantage of other investment opportunities. Market prices for such instruments may be volatile. During periods of substantial market volatility, an &lt;/span&gt;&lt;span style="clear:both;font-family:Arial, Helvetica, sans-serif;font-size:8.02pt;;"&gt;investment or even an entire market segment may become illiquid, sometimes abruptly, which can adversely affect the Fund&#x2019;s ability to limit losses. The Fund &lt;/span&gt;&lt;span style="clear:both;font-family:Arial, Helvetica, sans-serif;font-size:8.02pt;;"&gt;could lose money if it is unable to dispose of an investment at a time that is most beneficial to the Fund. The Fund may be required to dispose of investments &lt;/span&gt;&lt;span style="clear:both;font-family:Arial, Helvetica, sans-serif;font-size:8.02pt;;"&gt;at unfavorable times or prices to satisfy obligations, which may result in losses or may be costly to the Fund. &lt;/span&gt;&lt;span style="clear:both;font-family:Arial, Helvetica, sans-serif;font-size:8.02pt;;"&gt;&#160;&#x2009;For example, liquidity risk may be magnified in &lt;/span&gt;&lt;span style="clear:both;font-family:Arial, Helvetica, sans-serif;font-size:8.02pt;;"&gt;rising interest rate environments in the event of higher than normal redemption rates.&lt;/span&gt;&lt;span style="clear:both;font-family:Arial, Helvetica, sans-serif;font-size:8.02pt;;"&gt;&#160;&#x2009;Judgment plays a greater role in pricing illiquid investments than in &lt;/span&gt;&lt;span style="clear:both;font-family:Arial, Helvetica, sans-serif;font-size:8.02pt;;"&gt;investments with more active markets.&lt;/span&gt;&lt;/div&gt;</oef:RiskTextBlock>

The financial markets generally move in cycles, with periods of rising prices followed by &lt;/span&gt;&lt;span style="clear:both;font-family:Arial, Helvetica, sans-serif;font-size:8.02pt;;"&gt;periods of declining prices. The value of your investment may reflect these fluctuations. During a general downturn in the securities markets, multiple asset &lt;/span&gt;&lt;span style="clear:both;font-family:Arial, Helvetica, sans-serif;font-size:8.02pt;;"&gt;classes may decline in value simultaneously. Even when certain securities prices have generally increased over time, there have been periods of price decreases &lt;/span&gt;&lt;span style="clear:both;font-family:Arial, Helvetica, sans-serif;font-size:8.02pt;;"&gt;during those times, resulting in losses for investors, which are likely to occur again in the future.&lt;/span&gt;&lt;/div&gt;&lt;div&gt;&lt;span style="clear:both;font-family:Arial, Helvetica, sans-serif;font-size:8.02pt;;"&gt;Geopolitical and other events, including war, terrorism, trade disputes, pandemics, public health crises, natural disasters, and&#160;&#x2009;cybersecurity incidents, have led, &lt;/span&gt;&lt;span style="clear:both;font-family:Arial, Helvetica, sans-serif;font-size:8.02pt;;"&gt;and in the future may continue to lead, to general instability in world economies and markets and reduced liquidity in securities, which may negatively affect &lt;/span&gt;&lt;span style="clear:both;font-family:Arial, Helvetica, sans-serif;font-size:8.02pt;;"&gt;the value of your investment.&lt;/span&gt;&lt;/div&gt;&lt;div&gt;&lt;span style="clear:both;font-family:Arial, Helvetica, sans-serif;font-size:8.02pt;;"&gt;Policies established by the&#160;&#x2009;U.S. government and/or Federal Reserve and economic and political circumstances within the U.S. and abroad, such as inflation, &lt;/span&gt;&lt;span style="clear:both;font-family:Arial, Helvetica, sans-serif;font-size:8.02pt;;"&gt;changes in interest rates, recessions, changes in government leadership, a government&#x2019;s inability to agree on a budget, high public debt, the threat or &lt;/span&gt;&lt;span style="clear:both;font-family:Arial, Helvetica, sans-serif;font-size:8.02pt;;"&gt;occurrence of a federal government shutdown and threats or the occurrence of a failure to increase the federal government&#x2019;s debt limit, which could result in &lt;/span&gt;&lt;span style="clear:both;font-family:Arial, Helvetica, sans-serif;font-size:8.02pt;;"&gt;a default on the government&#x2019;s obligations, may negatively affect investor and consumer confidence and may negatively impact financial markets and the &lt;/span&gt;&lt;span style="clear:both;font-family:Arial, Helvetica, sans-serif;font-size:8.02pt;;"&gt;broader economy, perhaps suddenly and to a significant degree.&lt;/span&gt;&lt;/div&gt;&lt;div&gt;&lt;span style="clear:both;font-family:Arial, Helvetica, sans-serif;font-size:8.02pt;;"&gt;Markets and market participants are increasingly reliant upon public and proprietary data and systems.

As a result of such &lt;/span&gt;&lt;span style="clear:both;font-family:Arial, Helvetica, sans-serif;font-size:8.02pt;;"&gt;volatility, investment returns may fluctuate significantly. Moreover, during periods of significant volatility, the risks discussed herein associated with an &lt;/span&gt;&lt;span style="clear:both;font-family:Arial, Helvetica, sans-serif;font-size:8.02pt;;"&gt;investment in the Fund may be increased. National economies are substantially interconnected, as are global financial markets, which creates the possibility &lt;/span&gt;&lt;span style="clear:both;font-family:Arial, Helvetica, sans-serif;font-size:8.02pt;;"&gt;that conditions in one country or region might adversely impact issuers in a different country or region. However, the interconnectedness of economies and/&lt;/span&gt;&lt;span style="clear:both;font-family:Arial, Helvetica, sans-serif;font-size:8.02pt;;"&gt;or markets may be changing, which may impact such economies and markets in ways that cannot be foreseen at this time.&lt;/span&gt;&lt;br/&gt;&lt;span style="clear:both;font-family:Arial, Helvetica, sans-serif;font-size:8.02pt;;"&gt;Some countries, including the&#160;&#x2009;U.S., have adopted more protectionist trade policies, including trade tariffs and other trade barriers, which is a trend that &lt;/span&gt;&lt;span style="clear:both;font-family:Arial, Helvetica, sans-serif;font-size:8.02pt;;"&gt;appears to be continuing globally. The economies of all nations, including the U.S., are subject to the risks of slowing global economic growth, protectionist &lt;/span&gt;&lt;span style="clear:both;font-family:Arial, Helvetica, sans-serif;font-size:8.02pt;;"&gt;trade policies, inflationary pressures, limits imposed by international trade and security agreements, political or economic dysfunction, poor consumer &lt;/span&gt;&lt;span style="clear:both;font-family:Arial, Helvetica, sans-serif;font-size:8.02pt;;"&gt;sentiment, and reduced demand for goods due to fluctuating commodity prices and currency values, and these risks may create significant market volatility &lt;/span&gt;&lt;span style="clear:both;font-family:Arial, Helvetica, sans-serif;font-size:8.02pt;;"&gt;in ways that cannot be foreseen at the present time. These economic risks could have a negative impact on the Fund&#x2019;s investments.&lt;/span&gt;&lt;br/&gt;&lt;span style="clear:both;font-family:Arial, Helvetica, sans-serif;font-size:8.02pt;;"&gt;The U.S. Federal Reserve and certain foreign central banks have started to lower interest rates, though economic or other factors could stop or reverse such &lt;/span&gt;&lt;span style="clear:both;font-family:Arial, Helvetica, sans-serif;font-size:8.02pt;;"&gt;changes. It is difficult to accurately predict the various economic and political factors that influence the pace at which interest rates might change, the &lt;/span&gt;&lt;span style="clear:both;font-family:Arial, Helvetica, sans-serif;font-size:8.02pt;;"&gt;timing, frequency or magnitude of any such changes in interest rates, or when such changes might stop or again reverse course. Changes in interest rates &lt;/span&gt;&lt;span style="clear:both;font-family:Arial, Helvetica, sans-serif;font-size:8.02pt;;"&gt;could lead to an economic slowdown in the U.S. and abroad, significant market volatility and reduced liquidity in certain sectors of the market.&lt;/span&gt;&lt;br/&gt;&lt;span style="clear:both;font-family:Arial, Helvetica, sans-serif;font-size:8.02pt;;"&gt;Tensions, war, or open conflict between nations, such as &lt;/span&gt;&lt;span style="clear:both;font-family:Arial, Helvetica, sans-serif;font-size:8.02pt;;"&gt;among the United States, Israel and Iran, &lt;/span&gt;&lt;span style="clear:both;font-family:Arial, Helvetica, sans-serif;font-size:8.02pt;;"&gt;between Russia and Ukraine, &lt;/span&gt;&lt;span style="clear:both;font-family:Arial, Helvetica, sans-serif;font-size:8.02pt;;"&gt;otherwise &lt;/span&gt;&lt;span style="clear:both;font-family:Arial, Helvetica, sans-serif;font-size:8.02pt;;"&gt;in the Middle &lt;/span&gt;&lt;span style="clear:both;font-family:Arial, Helvetica, sans-serif;font-size:8.02pt;;"&gt;East or in eastern Asia could affect the economies of many nations, including the United States&lt;/span&gt;&lt;span style="clear:both;font-family:Arial, Helvetica, sans-serif;font-size:8.02pt;;"&gt; and may contribute to increased volatility and uncertainty in &lt;/span&gt;&lt;span style="clear:both;font-family:Arial, Helvetica, sans-serif;font-size:8.02pt;;"&gt;the financial markets. The extent and&lt;/span&gt;&lt;span style="clear:both;font-family:Arial, Helvetica, sans-serif;font-size:8.02pt;;"&gt; duration of ongoing hostilities and &lt;/span&gt;&lt;span style="clear:both;font-family:Arial, Helvetica, sans-serif;font-size:8.02pt;;"&gt;related sanctions and the repercussions of such events&lt;/span&gt;&lt;span style="clear:both;font-family:Arial, Helvetica, sans-serif;font-size:8.02pt;;"&gt; cannot be predicted. Those &lt;/span&gt;&lt;span style="clear:both;font-family:Arial, Helvetica, sans-serif;font-size:8.02pt;;"&gt;events &lt;/span&gt;&lt;span style="clear:both;font-family:Arial, Helvetica, sans-serif;font-size:8.02pt;;"&gt;have presented and could continue to &lt;/span&gt;&lt;span style="clear:both;font-family:Arial, Helvetica, sans-serif;font-size:8.02pt;;"&gt;present material uncertainty and risk with respect to markets globally&lt;/span&gt;&lt;span style="clear:both;font-family:Arial, Helvetica, sans-serif;font-size:8.02pt;;"&gt;, including in the oil and gas markets and &lt;/span&gt;&lt;span style="clear:both;font-family:Arial, Helvetica, sans-serif;font-size:8.02pt;;"&gt;potentially other industries and sectors, and&lt;/span&gt;&lt;span style="clear:both;font-family:Arial, Helvetica, sans-serif;font-size:8.02pt;;"&gt; the performance of the Fund and its investments or operations could be negatively impacted.&#160;&#x2009;&lt;/span&gt;&lt;br/&gt;&lt;span style="clear:both;font-family:Arial, Helvetica, sans-serif;font-size:8.02pt;;"&gt;Advancements in technology, including advanced development and increased regulation of artificial intelligence, may adversely impact market movements &lt;/span&gt;&lt;span style="clear:both;font-family:Arial, Helvetica, sans-serif;font-size:8.02pt;;"&gt;and liquidity. As artificial intelligence is used more widely, which can occur relatively rapidly, the profitability and growth of certain issuers and industries &lt;/span&gt;&lt;span style="clear:both;font-family:Arial, Helvetica, sans-serif;font-size:8.02pt;;"&gt;may be negatively impacted in ways that cannot be foreseen and could adversely impact issuer and market performance. As a consequence, the Fund&#x2019;s &lt;/span&gt;&lt;span style="clear:both;font-family:Arial, Helvetica, sans-serif;font-size:8.02pt;;"&gt;holdings and its overall performance could be negatively impacted.&lt;/span&gt;&lt;br/&gt;&lt;span style="clear:both;font-family:Arial, Helvetica, sans-serif;font-size:8.02pt;;"&gt;Global climate change may affect property and security values. Certain issuers, industries and regions may be adversely affected by the impacts of climate &lt;/span&gt;&lt;span style="clear:both;font-family:Arial, Helvetica, sans-serif;font-size:8.02pt;;"&gt;change in ways that cannot be foreseen. The impacts of legislation, regulation and international accords related to climate change, as well as any indirect &lt;/span&gt;&lt;span style="clear:both;font-family:Arial, Helvetica, sans-serif;font-size:8.02pt;;"&gt;consequences that may not be foreseen, may negatively impact certain issuers, industries and regions.&lt;/span&gt;&lt;/div&gt;

The ability of a municipal issuer to make payments can be affected by &lt;/span&gt;&lt;span style="clear:both;font-family:Arial, Helvetica, sans-serif;font-size:8.02pt;;"&gt;uncertainties in the municipal securities market, including: litigation; the strength of the local or national economy; the issuer&#x2019;s ability to raise revenues &lt;/span&gt;&lt;span style="clear:both;font-family:Arial, Helvetica, sans-serif;font-size:8.02pt;;"&gt;through tax or other means; budgetary constraints of local, state and federal governments upon which the issuer may be relying for funding; a legislature&#x2019;s &lt;/span&gt;&lt;span style="clear:both;font-family:Arial, Helvetica, sans-serif;font-size:8.02pt;;"&gt;willingness or ability to appropriate funds needed to pay municipal securities obligations; the bankruptcy of the issuer; adverse political and legislative &lt;/span&gt;&lt;span style="clear:both;font-family:Arial, Helvetica, sans-serif;font-size:8.02pt;;"&gt;changes, including to eliminate or limit the tax-exempt status of municipal bond interest or dividends; and other changes in the financial condition of a &lt;/span&gt;&lt;span style="clear:both;font-family:Arial, Helvetica, sans-serif;font-size:8.02pt;;"&gt;municipality. At times, municipal issuers have defaulted on obligations or commenced insolvency proceedings. Financial difficulties of municipal issuers may &lt;/span&gt;&lt;span style="clear:both;font-family:Arial, Helvetica, sans-serif;font-size:8.02pt;;"&gt;continue or get worse in the future. Reductions in tax rates may make municipal securities less attractive in comparison to taxable bonds. &lt;/span&gt;&lt;span style="clear:both;font-family:Arial, Helvetica, sans-serif;font-size:8.02pt;;"&gt;In addition, the &lt;/span&gt;&lt;span style="clear:both;font-family:Arial, Helvetica, sans-serif;font-size:8.02pt;;"&gt;Fund&#x2019;s investments in municipal securities are subject to the following risks:&lt;/span&gt;&lt;/div&gt;&lt;div&gt;

Holders of auction rate securities rely on the liquidity generated by the auction, and there is a risk that &lt;/span&gt;&lt;span style="clear:both;font-family:Arial, Helvetica, sans-serif;font-size:8.02pt;;"&gt;an auction will fail due to insufficient demand for the securities. If an auction fails, an auction rate security may become illiquid until a subsequent &lt;/span&gt;&lt;span style="clear:both;font-family:Arial, Helvetica, sans-serif;font-size:8.02pt;;"&gt;successful auction is conducted, the issuer redeems the issue, or a secondary market develops.&lt;/span&gt;&lt;/div&gt;

Consequently, timely payments depend on the issuer&#x2019;s credit quality, ability to raise tax revenues and ability to maintain an &lt;/span&gt;&lt;span style="clear:both;font-family:Arial, Helvetica, sans-serif;font-size:8.02pt;;"&gt;adequate tax base.

These are floating rate certificates that &lt;/span&gt;&lt;span style="clear:both;font-family:Arial, Helvetica, sans-serif;font-size:8.02pt;;"&gt;receive tax-exempt interest based on short-term rates and its holders may tender the certificates to the trust at face value.

Such securities may not be listed on an &lt;/span&gt;&lt;span style="clear:both;font-family:Arial, Helvetica, sans-serif;font-size:8.02pt;;"&gt;exchange and may have no active trading market. The prices of these securities may be more difficult to determine than publicly traded securities and these &lt;/span&gt;&lt;span style="clear:both;font-family:Arial, Helvetica, sans-serif;font-size:8.02pt;;"&gt;securities may involve heightened risk as compared to investments in securities of publicly traded companies. They may be more difficult to purchase or sell at &lt;/span&gt;&lt;span style="clear:both;font-family:Arial, Helvetica, sans-serif;font-size:8.02pt;;"&gt;an advantageous time or price because such securities may not be readily marketable in broad public markets or may have to be held for a certain time period &lt;/span&gt;&lt;span style="clear:both;font-family:Arial, Helvetica, sans-serif;font-size:8.02pt;;"&gt;before they can be resold.

Bonds issued to supply educational institutions with funds are subject to the risk of unanticipated revenue decline, &lt;/span&gt;&lt;span style="clear:both;font-family:Arial, Helvetica, sans-serif;font-size:8.02pt;;"&gt;primarily the result of decreasing student enrollment or decreased state and federal funding. Factors that may lead to declining or insufficient revenues &lt;/span&gt;&lt;span style="clear:both;font-family:Arial, Helvetica, sans-serif;font-size:8.02pt;;"&gt;include restrictions on students&#x2019; ability to pay tuition, availability of state and federal funding, and general economic conditions. Student loan revenue &lt;/span&gt;&lt;span style="clear:both;font-family:Arial, Helvetica, sans-serif;font-size:8.02pt;;"&gt;bonds are generally offered by state (or sub-state) authorities or commissions and are backed by pools of student loans. Risks associated with student loan &lt;/span&gt;&lt;span style="clear:both;font-family:Arial, Helvetica, sans-serif;font-size:8.02pt;;"&gt;revenue bonds include rate of student loan defaults, seasoning of the loan portfolio, student repayment deferral periods of forbearance, potential changes &lt;/span&gt;&lt;span style="clear:both;font-family:Arial, Helvetica, sans-serif;font-size:8.02pt;;"&gt;in federal legislation, state guarantee agency reimbursements, and continued federal interest and other program subsidies currently in effect.&lt;/span&gt;&lt;/div&gt;

The sub-advisor relies on prospectus &lt;/span&gt;&lt;span style="clear:both;font-family:Arial, Helvetica, sans-serif;font-size:8.02pt;;"&gt;disclosure of the tax opinion from the bond issuer&#x2019;s counsel as to the tax-exempt status of the investment. None of the Manager, the sub-advisor or the Fund &lt;/span&gt;&lt;span style="clear:both;font-family:Arial, Helvetica, sans-serif;font-size:8.02pt;;"&gt;guarantees that these opinions are correct, and there is no assurance that the U.S. Internal Revenue Service (&#x201c;IRS&#x201d;) will agree with the bond issuer&#x2019;s counsel&#x2019;s &lt;/span&gt;&lt;span style="clear:both;font-family:Arial, Helvetica, sans-serif;font-size:8.02pt;;"&gt;tax opinion. Interest payments from a security could become federally taxable, possibly retroactively to the date the security was issued, and the security could &lt;/span&gt;&lt;span style="clear:both;font-family:Arial, Helvetica, sans-serif;font-size:8.02pt;;"&gt;decline significantly in value. The interest on any money market instruments or other cash equivalents held by a Fund may be subject to federal, state and &lt;/span&gt;&lt;span style="clear:both;font-family:Arial, Helvetica, sans-serif;font-size:8.02pt;;"&gt;local income taxation and the federal Medicare contribution tax.&lt;/span&gt;&lt;/div&gt;&lt;div&gt;&lt;span style="clear:both;font-family:Arial, Helvetica, sans-serif;font-size:8.02pt;;"&gt;A significant restructuring of federal income tax rates, or even serious discussion on the topic in Congress, could cause municipal bond prices to fall. The &lt;/span&gt;&lt;span style="clear:both;font-family:Arial, Helvetica, sans-serif;font-size:8.02pt;;"&gt;demand for municipal securities is strongly influenced by the value of tax-exempt income to investors. Lower income tax rates could reduce the advantage of &lt;/span&gt;&lt;span style="clear:both;font-family:Arial, Helvetica, sans-serif;font-size:8.02pt;;"&gt;owning municipal securities.&lt;/span&gt;&lt;/div&gt;</oef:RiskTextBlock>

A variable rate security has a &lt;/span&gt;&lt;span style="clear:both;font-family:Arial, Helvetica, sans-serif;font-size:8.02pt;;"&gt;coupon that is adjusted at pre-designated periods in response to changes in the market rate of interest on which the coupon is based. The coupon on a &lt;/span&gt;&lt;span style="clear:both;font-family:Arial, Helvetica, sans-serif;font-size:8.02pt;;"&gt;floating rate security is generally based on an interest rate, such as a money-market index, Secured Overnight Financing Rate (&#x201c;SOFR&#x201d;), or a Treasury bill rate. &lt;/span&gt;&lt;span style="clear:both;font-family:Arial, Helvetica, sans-serif;font-size:8.02pt;;"&gt;Variable and floating rate securities are subject to interest rate risk and credit risk. As short-term interest rates decline, the coupons on variable and &lt;/span&gt;&lt;span style="clear:both;font-family:Arial, Helvetica, sans-serif;font-size:8.02pt;;"&gt;floating-rate securities typically decrease. Alternatively, during periods of rising short-term interest rates, the coupons on variable and floating-rate securities &lt;/span&gt;&lt;span style="clear:both;font-family:Arial, Helvetica, sans-serif;font-size:8.02pt;;"&gt;typically increase. Changes in the coupons of variable and floating-rate securities may lag behind changes in market rates or may have limits on the maximum &lt;/span&gt;&lt;span style="clear:both;font-family:Arial, Helvetica, sans-serif;font-size:8.02pt;;"&gt;increases in the coupon rates. The value of variable and floating-rate securities may decline if their coupons do not rise as much, or as quickly, as interest rates &lt;/span&gt;&lt;span style="clear:both;font-family:Arial, Helvetica, sans-serif;font-size:8.02pt;;"&gt;in general. Conversely, variable and floating rate securities will not generally increase in value if interest rates decline. Certain types of variable and floating &lt;/span&gt;&lt;span style="clear:both;font-family:Arial, Helvetica, sans-serif;font-size:8.02pt;;"&gt;rate instruments may be subject to greater liquidity risk than other debt securities.&lt;/span&gt;&lt;/div&gt;</oef:RiskTextBlock>

Accordingly, zero coupon securities usually trade at a deep discount from their face or par value and will be subject to greater fluctuations in market &lt;/span&gt;&lt;span style="clear:both;font-family:Arial, Helvetica, sans-serif;font-size:8.02pt;;"&gt;value in response to changing interest rates than debt obligations of comparable&#160;&#x2009;maturities that make current distribution of interest in cash. While interest &lt;/span&gt;&lt;span style="clear:both;font-family:Arial, Helvetica, sans-serif;font-size:8.02pt;;"&gt;payments are not made on such securities, the Fund accrues income with respect to these securities for federal income tax and accounting purposes. Longer &lt;/span&gt;&lt;span style="clear:both;font-family:Arial, Helvetica, sans-serif;font-size:8.02pt;;"&gt;term zero-coupon bonds are more exposed to interest rate risk than shorter term zero coupon bonds.&lt;/span&gt;&lt;/div&gt;</oef:RiskTextBlock>
