Alternative Minimum Tax Risk

Although the interest received from municipal securities is generally exempt from federal income tax, the Fund may invest in municipal securities subject to the federal alternative minimum tax. Accordingly, an investment in the Fund could cause shareholders to be subject to the federal alternative minimum tax.

Cash Transactions Risk

The Fund currently intends to effect creations and redemptions principally for cash, rather than for in-kind securities. For this reason, the Fund may be required to sell portfolio securities in order to obtain the cash needed to distribute redemption proceeds. The Fund may recognize a capital gain on these sales that might not have been incurred if the Fund had made a redemption in-kind. This may decrease the tax efficiency of the Fund compared to ETFs that utilize an in-kind redemption process.

Cyber Security Risk

The Fund is susceptible to operational risks through breaches in cyber security. Such events may cause the Fund to lose proprietary information, suffer data corruption or lose operational capacity and could cause the Fund to incur regulatory penalties, reputational damage, additional compliance costs associated with corrective measures and/or financial loss. In addition, cyber security breaches of the securities issuers or the Fund’s third-party service providers 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.

Derivatives Risk

Derivatives are investments whose value depends on (or is derived from) the value of an underlying instrument, such as a security, asset, reference rate or index and involve risks different from, and possibly greater than, the risks associated with other investments. These risks include: (i) the risk that the counterparty to a derivatives transaction may not fulfill its contractual obligations; (ii) risk of mispricing or improper valuation; and (iii) the risk that changes in the value of the derivative may not correlate perfectly with the underlying asset. A counterparty to a derivatives transaction with the Fund may be unable or unwilling to make timely principal, interest, settlement or margin payments, fulfill the delivery conditions of the contract or transaction, or otherwise honor its obligations. If a counterparty fails to meet its contractual obligations the Fund will have contractual remedies pursuant to the agreements related to the transaction, but the Fund may be unable to terminate or realize any gain on the investment or transaction, resulting in a loss to the Fund. The Fund may experience significant delays in obtaining any recovery in an insolvency, bankruptcy, or other reorganization proceeding involving a counterparty (including recovery of any collateral posted by it) and may obtain limited or no recovery in such circumstances.

Derivative prices are highly volatile and may fluctuate substantially during a short period of time. Such prices are influenced by numerous factors that affect the markets, including, but not limited to, changing supply and demand relationships, government programs and policies, national and international political and economic events, changes in interest rates, inflation and deflation, and changes in supply and demand relationships. Unlike other investments, derivative contracts often have leverage inherent in their terms. The effects of leverage may also cause the Fund to liquidate portfolio positions when it would not be advantageous to do so. In general, the use of leveraged derivatives can magnify potential for gain or loss and, therefore, amplify the effects of market volatility on the Fund’s Share price.

High Yield Municipal Bond Risk

Investments in high yield or below investment grade municipal bonds (commonly referred to as “junk bonds”) may be subject to increased liquidity risk as compared to other high yield debt securities. There may be little or no active trading market for certain high yield municipal bonds, which may make it difficult for the Fund to sell such bonds at or near their perceived value. In such cases, the value of a high yield municipal bond may decline dramatically, even during periods of declining interest rates. The high yield municipal bonds in which the Fund intends to invest may be more likely to pay interest that is includable in taxable income for purposes of the federal alternative minimum tax than other municipal bonds.

Income Risk

The Fund’s income may decline when interest rates fall or if there are defaults in its portfolio. This decline can occur because the Fund may subsequently invest in lower-yielding securities when securities in its portfolio mature or the Fund otherwise needs to purchase additional securities.

Issuer Risk

The performance of the Fund depends on the performance of individual securities to which the Fund has exposure. Changes to the financial condition or credit rating of an issuer of those securities may cause the value of the securities to decline.

Market Risk

Market risks include political, regulatory, market and economic developments, including developments that impact specific economic sectors, industries or segments of the market, which may affect the Fund’s value. Turbulence in financial markets, tariffs and other protectionist measures, political developments and uncertainty, central bank policy, and reduced liquidity in equity, credit and fixed income markets may negatively affect many issuers worldwide, which could have an adverse effect on the Fund. During a general downturn in the securities markets, multiple asset classes may be negatively affected. Geopolitical and other events, including war, terrorism, economic uncertainty, trade disputes, public health crises and related geopolitical events have led, and in the future may lead, to disruptions in the U.S. and world economies and markets, which may increase financial market volatility and have significant adverse direct or indirect effects on the Fund and its investments. Market disruptions could cause the Fund to lose money, experience significant redemptions, and encounter operational difficulties. Although multiple asset classes may be affected by a market disruption, the duration and effects may not be the same for all types of assets.

Municipal Bond Risk

Issuers, including governmental issuers, may be unable to pay their obligations as they come due. The values of Municipal Bonds 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 Bonds 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. This risk would be heightened to the extent that the Fund invests a substantial portion of its assets in Municipal Bonds issued pursuant to similar projects or whose interest is paid solely from revenues of similar projects. In addition, income from Municipal Bonds 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. There are various different types of Municipal Bonds, each with its own unique risk profile. Some of these risks include:

•Revenue Bonds (including Industrial Development Bonds) Risk — timely payments depend on the money earned by the particular facility or class of facilities, or the amount of revenues derived from another source, and may be negatively impacted by the general credit of the user of the facility;

•Moral Obligation Bonds Risk — moral obligation bonds are generally issued by special purpose public authorities of a state or municipality. If the issuer is unable to meet its obligations, repayment of these bonds becomes a moral commitment, but not a legal obligation, of the state or municipality;

•Municipal Lease Obligations Risk — in a municipal lease obligation, the issuer agrees to make payments when due on the lease obligation. Although the issuer does not pledge its unlimited taxing power for payment of the lease obligation, the lease obligation is secured by the leased property.

Municipal Insurance Risk

The Fund’s investments may include investments in insured Municipal Bonds. Municipal security insurance does not guarantee the value either of individual municipal securities or of Shares of the Fund. In addition, a municipal security insurance policy generally will not cover: (i) repayment of a municipal security before maturity (redemption), (ii) prepayment or payment of an acceleration premium (except for a mandatory sinking fund redemption) or any other provision of a bond indenture that advances the maturity of the bond or (iii) non-payment of principal or interest caused by negligence or bankruptcy of the paying agent. A mandatory sinking fund redemption may be a provision of a municipal security issue whereby part of the municipal security issue may be retired before maturity. Market conditions or changes to ratings criteria could adversely impact the ratings of Municipal Bond insurance companies. Downgrades and withdrawal of ratings from Municipal Bond insurers have substantially limited the availability of insurance sought by Municipal Bond issuers, thereby reducing the supply of insured Municipal Bonds that meet the Fund’s investment guidelines or the ability of the Fund to purchase insurance on Municipal Bonds held by the Fund. A rating downgrade of a Municipal Bond insurer could negatively impact the market value of insured Municipal Bonds held by the Fund. If the insurer of a defaulted Municipal Bond were to become unable or unwilling to pay the principal or interest on the defaulted Municipal Bond, the Fund would incur losses.

Operational Risk

The Fund is exposed to operational risks arising from a number of factors, including, but not limited to, human error, processing and communication errors, errors of the Fund’s service providers, counterparties or other third-parties, failed or inadequate processes and technology or systems failures. The Fund and Advisor seek to reduce these operational risks through controls and procedures. However, these measures do not address every possible risk and may be inadequate to address significant operational risks.

Private Placement and Restricted Securities Risk

The Fund may invest in privately issued securities, including those which may be resold only in accordance with Rule 144A under the Securities Act of 1933, as amended. Securities acquired in a private placement generally are subject to strict restrictions on resale, and there may be no market or a limited market for the resale of such securities. Therefore, the Fund may be unable to dispose of such securities when it desires to do so or at the most favorable price. This potential lack of liquidity also may make it more difficult to accurately value these securities.

Trading Price Risk

Although it is generally expected that the market price of the Fund’s Shares will approximate the Fund’s NAV, there may be times when the market price and the NAV vary significantly. Shares of the Fund trade on securities exchanges at prices at, above or below the Fund’s most recent NAV. The NAV of the Fund is calculated at the end of each business day and fluctuates with changes in the market value of the Fund’s holdings. The trading price of the Fund’s Shares fluctuates continuously throughout trading hours based on market supply of and demand for Shares and the Fund’s NAV, among other reasons. As a result, the trading prices of the Fund’s Shares may deviate significantly from NAV during periods of market volatility. The market price of the Fund’s Shares during the trading day, like the price of any exchange-traded security, includes a “bid/ask” spread charged by market makers or other participants that trade the Shares. In times of severe market disruption, the bid/ask spread can increase significantly. At those times, Shares are most likely to be traded at a discount to NAV, and the discount is likely to be greatest when the price of Shares is falling fastest, which may be the time that an investor most wants to sell their Shares. The risk of wide bid and ask spreads may be especially pronounced for smaller funds. In addition, increased market volatility may cause wider spreads.

Variable and Floating Rate Instruments Risk

Variable and floating rate instruments include debt securities issued by corporate and governmental entities, bank loans, mortgage-backed securities and asset-backed securities, preferred equity securities and derivative variable rate securities, such as inverse floaters. Variable and floating rate instruments are structured so that the instrument’s coupon rate fluctuates based upon the level of a reference rate. A variable or floating rate instrument’s coupon rate resets periodically according to its terms. Consequently, in a rising interest rate environment, variable and floating rate instruments with coupon rates that reset infrequently may lag behind the changes in market interest rates.
