RMM RiverNorth Managed Duration Municipal Income Fund Inc

WHAT IS THE FUND’S INVESTMENT STRATEGY?

The RiverNorth Managed Duration Municipal Income Fund, Inc. seeks to provide current income exempt from regular U.S. federal income taxes (but which may be includable in taxable income for purposes of the Federal alternative minimum tax) with a secondary objective of total return.

The Fund’s Managed Assets (as defined in Note 2, below) are allocated among two principal strategies: Tactical Municipal Closed-End Fund (CEF) Strategy managed by RiverNorth Capital Management, LLC (“RiverNorth”), and Municipal Bond Income Strategy managed by MacKay Shields LLC ("MacKay Shields").

RiverNorth determines the portion of the Fund's assets to allocate to each strategy and may, from time to time, adjust the allocations. The Fund may allocate between 25% to 50% of its Managed Assets to the Tactical Municipal CEF Strategy and 50% to 75% of its Managed Assets to the Municipal Bond Income Strategy.

The Tactical Municipal CEF Strategy typically invests in municipal CEFs and exchange-traded funds (ETFs) and other investment companies seeking to derive value from the discount and premium spreads associated with CEFs. The Municipal Bond Income Strategy primarily invests in municipal debt securities of any credit quality, including securities that are rated below investment grade. RiverNorth and MacKay Shields may use various techniques to manage the duration of the Fund's portfolio in an attempt to mitigate the risks associated with changes in interest rates. Under normal market conditions, the Fund will seek to maintain Managed Assets with a weighted average effective duration of the Bloomberg Barclays Municipal Bond Index.

August 27, 2021

The Fund has an automatic dividend reinvestment plan commonly referred to as an “opt-out” plan. Unless the registered owner of Common Shares elects to receive cash by contacting DST Systems, Inc. (the “Plan Administrator”), all dividends declared on Common Shares will be automatically reinvested by the Plan Administrator for shareholders in the Fund’s Automatic Dividend Reinvestment Plan (the “Plan”), in additional Common Shares. Common Shareholders who elect not to participate in the Plan will receive all dividends and other distributions in cash paid by check mailed directly to the shareholder of record (or, if the Common Shares are held in street or other nominee name, then to such nominee) by the Plan Administrator as dividend disbursing agent. Participation in the Plan is completely voluntary and may be terminated or resumed at any time without penalty by notice if received and processed by the Plan Administrator prior to the dividend record date; otherwise such termination or resumption will be effective with respect to any subsequently declared dividend or other distribution. Such notice will be effective with respect to a particular dividend or other distribution (together, a “Dividend”). Some brokers may automatically elect to receive cash on behalf of Common Shareholders and may re-invest that cash in additional Common Shares. Reinvested Dividends will increase the Fund’s Managed Assets on which the management fee is payable to the Adviser (and by the Adviser to the Sub-Adviser).

Whenever the Fund declares a Dividend payable in cash, non-participants in the Plan will receive cash and participants in the Plan will receive the equivalent in Common Shares. The Common Shares will be acquired by the Plan Administrator for the participants’ accounts, depending upon the circumstances described below, either (i) through receipt of additional unissued but authorized Common Shares from the Fund (“Newly Issued Common Shares”) or (ii) by purchase of outstanding Common Shares on the open market (“Open-Market Purchases”) on the NYSE or elsewhere. If, on the payment date for any Dividend, the closing market price plus estimated brokerage commissions per Common Share is equal to or greater than the NAV per Common Share, the Plan Administrator will invest the Dividend amount in Newly Issued Common Shares on behalf of the participants. The number of Newly Issued Common Shares to be credited to each participant’s account will be determined by dividing the dollar amount of the Dividend by the Fund’s NAV per Common Share on the payment date. If, on the payment date for any Dividend, the NAV per Common Share is greater than the closing market value plus estimated brokerage commissions (i.e., the Fund’s Common Shares are trading at a discount), the Plan Administrator will invest the Dividend amount in Common Shares acquired on behalf of the participants in Open-Market Purchases.

In the event of a market discount on the payment date for any Dividend, the Plan Administrator will have until the last business day before the next date on which the Common Shares trade on an “ex-dividend” basis or 30 days after the payment date for such Dividend, whichever is sooner (the “Last Purchase Date”), to invest the Dividend amount in Common Shares acquired in Open-Market Purchases. It is contemplated that the Fund will pay monthly income Dividends. If, before the Plan Administrator has completed its Open-Market Purchases, the market price per Common Share exceeds the NAV per Common Share, the average per Common Share purchase price paid by the Plan Administrator may exceed the NAV of the Common Shares, resulting in the acquisition of fewer Common Shares than if the Dividend had been paid in Newly Issued Common Shares on the Dividend payment date. Because of the foregoing difficulty with respect to Open-Market Purchases, the Plan provides that if the Plan Administrator is unable to invest the full Dividend amount in Open-Market Purchases during the purchase period or if the market discount shifts to a market premium during the purchase period, the Plan Administrator may cease making Open-Market Purchases and may invest the uninvested portion of the Dividend amount in Newly Issued Common Shares at the NAV per Common Share at the close of business on the Last Purchase Date.

The Plan Administrator maintains all shareholders’ accounts in the Plan and furnishes written confirmation of all transactions in the accounts, including information needed by shareholders for tax records. Common Shares in the account of each Plan participant will be held by the Plan Administrator on behalf of the Plan participant, and each shareholder proxy will include those shares purchased or received pursuant to the Plan. The Plan Administrator will forward all proxy solicitation materials to participants and vote proxies for shares held under the Plan in accordance with the instructions of the participants.

Beneficial owners of Common Shares who hold their Common Shares in the name of a broker or nominee should contact the broker or nominee to determine whether and how they may participate in the Plan. In the case of Common Shareholders such as banks, brokers or nominees which hold shares for others who are the beneficial owners, the Plan Administrator will administer the Plan on the basis of the number of Common Shares certified from time to time by the record shareholder’s name and held for the account of beneficial owners who participate in the Plan.

There will be no brokerage charges with respect to Common Shares issued directly by the Fund. However, each participant will pay a pro rata share of brokerage commissions incurred in connection with Open-Market Purchases. The automatic reinvestment of Dividends will not relieve participants of any federal, state or local income tax that may be payable (or required to be withheld) on such Dividends, even though such participants have not received any cash with which to pay the resulting tax. See “U.S. Federal Income Tax Matters” below. Participants that request a sale of Common Shares through the Plan Administrator are subject to brokerage commissions.

The Fund reserves the right to amend or terminate the Plan. There is no direct service charge to participants with regard to purchases in the Plan; however, the Fund reserves the right to amend the Plan to include a service charge payable by the participants. All correspondence or questions concerning the Plan should be directed to the Plan Administrator at (844) 569-4750.

UNAUDITED TAX INFORMATION

For the calendar year ended December 31, 2020, 98.12% of the distributions from net investment income for the RiverNorth Managed Duration Municipal Income Fund were exempt from federal income tax.

In early 2021, if applicable, shareholders of record received this information for the distributions paid to them by the Fund during the calendar year 2020 via Form 1099. The Fund will notify shareholders in early 2022 of amounts paid to them by the Fund, if any, during the calendar year 2021.

The following information in this annual report is a summary of certain information about the Fund and changes since the Fund’s most recent annual report as of June 30, 2021 (the “prior disclosure date”). This information may not reflect all of the changes that have occurred since you purchased the Fund.

Investment Objectives

There have been no changes in the Fund’s investment objectives since the prior disclosure date that have not been approved by shareholders.

The Fund’s primary investment objective is current income exempt from regular U.S. federal income taxes (but which may be includable in taxable income for purposes of the Federal alternative minimum tax). The Fund’s secondary investment objective is total return.

Principal Investment Strategies and Policies

There have been no changes in the Fund’s Principal Investment Strategies and Policies since the prior disclosure date.

Under normal market conditions, the Fund seeks to achieve its investment objectives by investing, directly or indirectly, at least 80% of its Managed Assets in municipal bonds, the interest on which is, in the opinion of bond counsel to the issuers, generally excludable from gross income for regular U.S. federal income tax purposes, except that the interest may be includable in taxable income for purposes of the Federal alternative minimum tax (“Municipal Bonds”). In order to qualify to pay exempt-interest dividends, which are items of interest excludable from gross income for federal income tax purposes, the Fund seeks to invest at least 50% of its Managed Assets either directly (and indirectly through tender option bond transactions) in such Municipal Bonds or in other funds that are taxed as regulated investment companies. In addition, under normal market conditions, the Fund will seek to maintain Managed Assets with a weighted average effective duration that is within three years of the weighted average effective duration of the Bloomberg Barclays Municipal Bond Index.

Municipal Bonds are debt obligations, which may have a variety of issuers, including governmental entities or other qualifying issuers. Issuers may be states, territories and possessions of the United States and the District of Columbia and their political subdivisions, agencies and instrumentalities. Such territories of the United States include Puerto Rico. Municipal Bonds include, among other instruments, general obligation bonds, revenue bonds, municipal leases, certificates of participation, private activity bonds, moral obligation bonds, and tobacco settlement bonds, as well as short-term, tax-exempt obligations such as municipal notes and variable rate demand obligations.

The Fund seeks to allocate its assets between the two principal strategies described below. RiverNorth Capital Management, LLC (the “Adviser”) determines the portion of the Fund’s Managed Assets to allocate to each strategy and may, from time to time, adjust the allocations. Under normal market conditions, the Fund may allocate between 25% and 50% of its Managed Assets to the Tactical Municipal Closed-End Fund Strategy and 50% to 75% of its Managed Assets to the Municipal Bond Income Strategy.

Tactical Municipal Closed-End Fund Strategy (25%-50% of Managed Assets). This strategy seeks to (i) generate returns through investments in closed-end funds, exchange-traded funds (“ETFs”) and other investment companies (collectively, the “Underlying Funds”) that invest, under normal market conditions, at least 80% of their net assets, plus the amount of any borrowings for investment purposes, in Municipal Bonds, and (ii) derive value from the discount and premium spreads associated with closed-end funds that invest, under normal market conditions, at least 80% of their net assets, plus the amount of any borrowings for investment purposes, in Municipal Bonds. All Underlying Funds will be registered under the Securities Act of 1933, as amended (the “Securities Act”).

Under normal market conditions, the Fund limits its investments in closed-end funds that have been in operation for less than one year to no more than 10% of the Fund’s Managed Assets allocated to the Tactical Municipal Closed-End Fund Strategy. The Fund will not invest in inverse ETFs or leveraged ETFs. Under normal market conditions, the Fund may not invest more than 20% of its Managed Assets in the Tactical Municipal Closed-End Fund Strategy in single state municipal closed-end funds. The Fund’s shareholders will indirectly bear the expenses, including the management fees, of the Underlying Funds.

Under Section 12(d)(1)(A) of the 1940 Act, the Fund may hold securities of an Underlying Fund in amounts which (i) do not exceed 3% of the total outstanding voting stock of the Underlying Fund, (ii) do not exceed 5% of the value of the Fund’s total assets and (iii) when added to all other Underlying Fund securities held by the Fund, do not exceed 10% of the value of the Fund’s total assets. These limits may be exceeded when permitted under Rule 12d1-4. The Fund intends to rely on either Section 12(d)(1)(F) of the 1940 Act, which provides that the provisions of Section 12(d)(1)(A) shall not apply to securities purchased or otherwise acquired by the Fund if (i) immediately after such purchase or acquisition not more than 3% of the total outstanding stock of such Underlying Fund is owned by the Fund and all affiliated persons of the Fund, and (ii) certain requirements are met with respect to sales charges, or Rule 12d1-4.

The Fund may invest in Underlying Funds that invest in securities that are rated below investment grade, including those receiving the lowest ratings from Standard & Poor’s Ratings Services, a Standard & Poor’s Financial Services LLC business (“S&P”), Fitch Ratings, a part of the Fitch Group (“Fitch”), or Moody’s Investor Services, Inc. (“Moody’s”), or comparably rated by another nationally recognized statistical rating organization (“NRSRO”) or, if unrated, determined by the Adviser or MacKay Shields LLC (the “Subadviser”) to be of comparable credit quality, which indicates that the security is in default or has little prospect for full recovery of principal or interest. Below investment grade securities (such as securities rated below BBB- by S&P or Fitch or below Baa3 by Moody’s) are commonly referred to as “junk” and “high yield” securities. Below investment grade securities are considered speculative with respect to the issuer’s capacity to pay interest and repay principal. The Underlying Funds in which the Fund invests may invest in securities receiving the lowest ratings from the NRSROs, including securities rated C by Moody’s or D- by S&P. Lower rated below investment grade securities are considered more vulnerable to nonpayment than other below investment grade securities and their issuers are more dependent on favorable business, financial and economic conditions to meet their financial commitments. The lowest rated below investment grade securities are typically already in default.

The Underlying Funds in which the Fund invests will not include those that are advised or subadvised by the Adviser, the Subadviser or their affiliates.

Municipal Bond Income Strategy (50%-75% of Managed Assets). This strategy seeks to capitalize on inefficiencies in the tax-exempt and tax-advantaged securities markets through investments in Municipal Bonds. Under normal market conditions, the Fund may not directly invest more than 25% of the Managed Assets allocated to the Municipal Bond Income Strategy in Municipal Bonds in any one industry or in any one state of origin, and the Fund may not directly invest more than 5% of the Managed Assets allocated to this strategy in the Municipal Bonds of any one issuer, except that the foregoing industry and issuer restrictions shall not apply to general obligation bonds and the Fund will consider the obligor or borrower underlying the Municipal Bond to be the “issuer.” The Fund may invest up to 30% of the Managed Assets allocated to the Municipal Bond Income Strategy in Municipal Bonds that pay interest that may be includable in taxable income for purposes of the Federal alternative minimum tax. The Fund can invest, directly or indirectly through Underlying Funds, in bonds of any maturity; however, under this strategy, it will generally invest in Municipal Bonds that have a maturity of five years or longer at the time of purchase.

Under normal market conditions, the Fund invests at least 65% of the Fund’s Managed Assets allocated to the Municipal Bond Income Strategy directly in investment grade Municipal Bonds. The Subadviser invests no more than 20% of the Managed Assets allocated to the Municipal Bond Income Strategy in Municipal Bonds rated at or below Caa1 by Moody’s or CCC+ by S&P or Fitch, or comparably rated by another NRSRO, including unrated bonds judged to be of equivalent quality as determined by the Adviser or Subadviser, as applicable. Investment grade securities are those rated Baa or higher by Moody’s (although Moody’s considers securities rated Baa to have speculative characteristics) or BBB or higher by S&P or rated similarly by another NRSRO or, if unrated, judged to be of equivalent quality as determined by the Adviser or Subadviser, as applicable. If the independent ratings agencies assign different ratings to the same security, the Fund will use the higher rating for purposes of determining the security’s credit quality. Subject to the foregoing limitations, the Fund may invest in securities receiving the lowest ratings from the NRSROs, including securities rated C by Moody’s or D-by S&P, which indicates that the security is in default or has little prospect for full recovery of principal or interest.

Under normal market conditions, the Fund, or the Underlying Funds in which the Fund invests, invests at least 50% of its Managed Assets, directly or indirectly in investment grade Municipal Bonds.

“Managed Assets” means the total assets of the Fund, including assets attributable to leverage, minus liabilities (other than debt representing leverage and any preferred stock that may be outstanding). Such assets attributable to leverage include the portion of assets in tender option bond trusts of which the Fund owns TOB Residuals (as defined below) that has been effectively financed by the trust’s issuance of TOB Floaters (as defined below).

Managed Duration Strategy. The Adviser and the Subadviser may use various techniques to manage the duration of the Fund’s portfolio in an attempt to mitigate the risks associated with changes in interest rates. Under normal market conditions, the Fund will seek to maintain Managed Assets with a weighted average effective duration (excluding effects of leverage) that targets the weighted average effective duration of the Bloomberg Barclays Municipal Bond Index, a widely recognized municipal bond index (the “Index”), primarily through its investments in Municipal Bonds and

Underlying Funds as well as through short positions in U.S. Treasury futures contracts (as discussed below). As a result of, among other things, changing market conditions and differences between the Fund’s portfolio and the Index, the Fund believes it will generally be able to maintain a weighted average effective duration that is within three years of the weighted average effective duration of the Index. However, under certain market conditions and from time to time for the reasons described below, the Fund’s duration may be outside of such range. In addition, if the effect of the Fund’s use of leverage was included in calculating duration, it could result in a longer duration for the Fund. The Fund may invest in bonds of any maturity, whether directly through Municipal Bonds or indirectly through Underlying Funds.

Effective duration is a mathematical calculation of the sensitivity of the price of a bond to changes in interest rates, measuring a bond’s expected life on a present value basis, taking into account the bond’s yield, interest payments, final maturity and, in the case of a bond with an embedded option (e.g., the right of the issuer to call the bond prior to maturity, or a sinking fund schedule), the probability that the option will be exercised. The longer the effective duration of a bond or a group of bonds, the more sensitive the bond or group of bonds is to changes in interest rates; the shorter the duration, the less sensitive the bond or group of bonds is to such changes. In general, each year of duration represents an expected 1% change in the value of a bond for every 1% immediate change in interest rates. For example, if the Fund’s portfolio has an average effective duration of five years, its value would be expected to fall by approximately 5% if interest rates rise by 1%. Conversely, the portfolio’s value would be expected to rise about 5% if interest rates fell by 1%.

The Adviser and the Subadviser will invest with a view to managing the duration of the Fund. However, the calculation of the Fund’s weighted average effective duration will be contingent upon the Adviser’s ability to adequately determine the weighted average effective duration of each of the Underlying Funds in which it invests, which will inherently be limited as the Adviser’s determination will primarily depend on reporting by such Underlying Funds. Such Underlying Fund reporting will likely be on a delayed basis and could be subject to incomplete or inaccurate information that may not be readily apparent to the Adviser. As a result, the Fund cannot guarantee the precise overall weighted average effective duration of its portfolio at any given point in time and this limitation could cause the Fund’s weighted average effective duration to be outside of its targeted duration range.

In addition, the Adviser and Subadviser may use short sales and derivatives such as options, futures contracts, options on futures contracts, and swaps (collectively, “Hedging Positions”) to manage the duration of the Fund. Such Hedging Positions may, however, result in income or gain to the Fund that is not exempt from regular U.S. federal income taxes.

A short sale is a transaction in which the Fund sells a security that it does not own in anticipation of a decline in the market price of the security. The Fund may benefit from a short position when the shorted security decreases in value. The Fund initially anticipates using short positions primarily on U.S. Treasury futures contracts. The Fund will not engage in any short sales of securities issued by closed-end funds.

Other Investments. The Fund may invest, directly or indirectly, up to 20% of its Managed Assets in taxable municipal securities. Any portion of the Fund’s assets invested in taxable municipal securities do not count toward the 50%-75% of the Fund’s assets allocated to Municipal Bonds.

The Fund also may attempt to enhance the return on the cash portion of its portfolio by investing in total return swap agreements. A total return swap agreement provides the Fund with a return based on the performance of an underlying asset, in exchange for fee payments to a counterparty based on a specific rate. The difference in the value of these income streams is recorded daily by the Fund, and is typically settled in cash at least monthly. If the underlying asset declines in value over the term of the swap, the Fund would be required to pay the dollar value of that decline plus any applicable fees to the counterparty. The Fund may use its own net asset value (“NAV”) or any other reference asset that the Adviser or Subadviser chooses as the underlying asset in a total return swap. The Fund limits the notional amount of all total return swaps in the aggregate to 15% of the Fund’s Managed Assets.

In addition to the foregoing principal investment strategies of the Fund, the Adviser also may allocate the Fund’s Managed Assets among cash and short-term investments. There are no limits on the Fund’s portfolio turnover, and the Fund may buy and sell securities to take advantage of potential short-term trading opportunities without regard to length of time and when the Adviser or Subadviser believes investment considerations warrant such action.

All percentage limitations are measured at the time of investment and may be exceeded on a going-forward basis as a result of credit rating downgrades or market value fluctuations of the Fund’s portfolio securities. Unless otherwise specified herein, the Fund may count its holdings in Underlying Funds towards various guideline tests, including the 80% policy so long as the earnings on the underlying holdings of such Underlying Funds are exempt from regular U.S. federal income taxes (but which may be includable in taxable income for purposes of the Federal alternative minimum tax).

Unless otherwise specified, the investment policies and limitations of the Fund are not considered to be fundamental by the Fund and can be changed without a vote of the common shareholders. The Fund’s primary investment objective, 80% policy and certain investment restrictions specifically identified as such in the Fund’s Statement of Additional Information are considered fundamental and may not be changed without the approval of the holders of a majority of the outstanding voting securities of the Fund, as defined in the 1940 Act, which includes common shares and Preferred Shares, if any, voting together as a single class, and the holders of the outstanding Preferred Shares, if any, voting as a single class.

Portfolio Composition

Set forth below is a description of the various types of Municipal Bonds in which the Fund may invest. Obligations are included within the term “Municipal Bonds” if the interest paid thereon is excluded from gross income for U.S. federal income tax purposes in the opinion of bond counsel to the issuer.

Municipal Bonds are either general obligation or revenue bonds and typically are issued to finance public projects, such as roads or public buildings, to pay general operating expenses or to refinance outstanding debt. Municipal Bonds may also be issued for private activities, such as housing, medical and educational facility construction or for privately owned industrial development and pollution control projects. General obligation bonds are backed by the full faith and credit and taxing authority of the issuer and may be repaid from any revenue source. Revenue bonds may be repaid only from the revenues of a specific facility or source. The Fund also may purchase Municipal Bonds that represent lease obligations. These carry special risks because the issuer of the bonds may not be obligated to appropriate money annually to make payments under the lease.

The Municipal Bonds in which the Fund primarily invests pay interest or income that, in the opinion of bond counsel to the issuer, is exempt from regular U.S. federal income tax. The Adviser and the Subadviser will not conduct their own analysis of the tax status of the interest paid by Municipal Bonds held by the Fund, but will rely on the opinion of counsel to the issuer of each such instrument. The Fund may also invest in Municipal Bonds issued by United States Territories (such as Puerto Rico or Guam) that are exempt from regular U.S. federal income tax. In addition, the Fund may invest in other securities that pay interest or income that is, or make other distributions that are, exempt from regular U.S. federal income tax and/or state and local taxes, regardless of the technical structure of the issuer of the instrument. The Fund treats all of such tax-exempt securities as Municipal Bonds.

The yields on Municipal Bonds are dependent on a variety of factors, including prevailing interest rates and the condition of the general money market and the municipal bond market, the size of a particular offering, the maturity of the obligation and the rating of the issuer. The market value of Municipal Bonds will vary with changes in interest rate levels and as a result of changing evaluations of the ability of bond issuers to meet interest and principal payments.

General Obligation Bonds. General obligation bonds are backed by the issuer’s full faith and credit and taxing authority for the payment of principal and interest. The taxing authority of any governmental entity may be limited, however, by provisions of its state constitution or laws, and an entity’s creditworthiness will depend on many factors, including potential erosion of its tax base due to population declines, natural disasters, declines in the state’s industrial base or inability to attract new industries, economic limits on the ability to tax without eroding the tax base, state legislative proposals or voter initiatives to limit ad valorem real property taxes (i.e., taxes based upon an assessed value of the property) and the extent to which the entity relies on federal or state aid, access to capital markets or other factors beyond the state’s or entity’s control. Accordingly, the capacity of the issuer of a general obligation bond as to the timely payment of interest and the repayment of principal when due is affected by the issuer’s maintenance of its tax base.

Revenue Bonds. Revenue bonds are payable only from the revenues derived from a particular facility or class of facilities or, in some cases, from the proceeds of a special excise tax or other specific revenue sources such as payments from the user of the facility being financed. Accordingly, the timely payment of interest and the repayment of principal in accordance with the terms of the revenue or special obligation bond is a function of the economic viability of such facility or such revenue source.

Private Activity Bonds. Private activity bonds are issued by or on behalf of public authorities to obtain funds to provide privately operated housing facilities, airport, mass transit or port facilities, sewage disposal, solid waste disposal or hazardous waste treatment or disposal facilities and certain local facilities for water supply, gas or electricity. Other types of private activity bonds, the proceeds of which are used for the construction, equipping, repair or improvement of privately operated industrial or commercial facilities, may constitute Municipal Bonds, although the current U.S. federal income tax laws place substantial limitations on the size of such issues.

Private activity bonds are secured primarily by revenues derived from loan repayments or lease payments due from the entity, which may or may not be guaranteed by a parent company or otherwise secured. Private activity bonds generally are not secured by a pledge of the taxing power of the issuer of such bonds. Therefore, an investor should be aware that repayment of such bonds generally depends on the revenues of a private entity and be aware of the risks that such an investment may entail. Continued ability of an entity to generate sufficient revenues for the payment of principal and interest on such bonds will be affected by many factors including the size of the entity, capital structure, demand for its products or services, competition, general economic conditions, government regulation and the entity’s dependence on revenues for the operation of the particular facility being financed. The Fund expects that, due to investments in private activity bonds, a portion of the distributions it makes on the Common Shares will be includable in the federal alternative minimum taxable income.

Moral Obligation Bonds. The Fund also may invest in “moral obligation” bonds, which are normally issued by special purpose public authorities. If an issuer of moral obligation bonds is unable to meet its obligations, the repayment of such bonds becomes a moral commitment but not a legal obligation of the state or municipality in question.

Municipal Lease Obligations and Certificates of Participation. Also included within the general category of Municipal Bonds are participations in lease obligations or installment purchase contract obligations of municipal authorities or entities (hereinafter collectively called “Municipal Lease Obligations”). Although a Municipal Lease Obligation does not constitute a general obligation of the municipality for which the municipality’s taxing power is pledged, a Municipal Lease Obligation is ordinarily backed by the municipality’s covenant to budget for, appropriate and make the payments due under the Municipal Lease Obligation. However, certain Municipal Lease Obligations contain “non-appropriation” clauses which provide that the municipality has no obligation to make lease or installment purchase payments in future years unless money is appropriated for such purpose on a yearly basis. In the case of a “non-appropriation” lease, a Fund’s ability to recover under the lease in the event of non-appropriation or default will be limited solely to the repossession of the leased property, without recourse to the general credit of the lessee, and the disposition or re-leasing of the property might prove difficult. A certificate of participation represents an undivided interest in an unmanaged pool of municipal leases, an installment purchase agreement or other instruments. The certificates are typically issued by a municipal agency, a trust or other entity that has received an assignment of the payments to be made by the state or political subdivision under such leases or installment purchase agreements. In addition, such participations generally provide the Fund with the right to demand payment, on not more than seven days’ notice, of all or any part of the Fund’s participation interest in the underlying leases, plus accrued interest.

Tobacco Settlement Bonds. Included in the general category of Municipal Bonds in which the Fund may invest are “tobacco settlement bonds.” The Fund may invest in tobacco settlement bonds, which are municipal securities that are backed solely by expected revenues to be derived from lawsuits involving tobacco related deaths and illnesses which were settled between certain states and American tobacco companies. Tobacco settlement bonds are secured by an issuing state’s proportionate share in the Master Settlement Agreement (“MSA”). The MSA is an agreement, reached out of court in November 1998 between 46 states and nearly all of the U.S. tobacco manufacturers. The MSA provides for annual payments in perpetuity by the manufacturers to the states in exchange for releasing all claims against the manufacturers and a pledge of no further litigation. Tobacco manufacturers pay into a master escrow trust based on their market share, and each state receives a fixed percentage of the payment as set forth in the MSA. A number of states have securitized the future flow of those payments by selling bonds pursuant to indentures or through distinct governmental entities created for such purpose. The principal and interest payments on the bonds are backed by the future revenue flow related to the MSA. Annual payments on the bonds, and thus risk to the Fund, are highly dependent on the receipt of future settlement payments to the state or its governmental entity.

Zero Coupon Bonds. The Fund may invest in zero-coupon bonds. A zero coupon bond is a bond that does not pay interest either for the entire life of the obligation or for an initial period after the issuance of the obligation. When held to its maturity, its return comes from the difference between the purchase price and its maturity value. A zero coupon bond is normally issued and traded at a deep discount from face value. Zero coupon bonds allow an issuer to avoid or delay the need to generate cash to meet current interest payments and, as a result, may involve greater credit risk than bonds that pay interest currently or in cash. The market prices of zero coupon bonds are affected to a greater extent by changes in prevailing levels of interest rates and thereby tend to be more volatile in price than securities that pay interest periodically. In addition, the Fund would be required to distribute the income on any of these instruments as it accrues, even though the Fund will not receive all of the income on a current basis or in cash. Thus, the Fund may have to sell other investments, including when it may not be advisable to do so, to make income distributions to its common shareholders.

Use of Leverage

The Fund may borrow money and/or issue preferred shares, notes or debt securities for investment purposes. These practices are known as leveraging. In addition, the Fund may enter into derivative and other transactions that have the effect of leverage. Such other transactions may include tender option bond transactions (as described herein). The Adviser determines whether or not to engage in leverage based on its assessment of conditions in the debt and credit markets. As of the time immediately after it enters into any of the foregoing transactions, the Fund will seek to limit its overall effective leverage to 45% of its Managed Assets.

The Fund currently utilizes leverage obtained through the use of proceeds received from tender option bond transactions. To date, the Fund has not issued any preferred shares or debt securities.

Under the 1940 Act, the Fund is not permitted to incur indebtedness unless immediately after doing so the Fund has an asset coverage of at least 300% of the aggregate outstanding principal balance of indebtedness (i.e., such indebtedness may not exceed 33 1/3% of the value of the Fund’s total assets including the amount borrowed). Additionally, under the 1940 Act, the Fund may not declare any dividend or other distribution upon any class of its shares, or purchase any such shares, unless the aggregate indebtedness of the Fund has, at the time of the declaration of any such dividend or distribution or at the time of any such purchase, asset coverage of at least 300% after deducting the amount of such dividend, distribution, or purchase price, as the case may be. Under the 1940 Act, the Fund is not permitted to issue Preferred Shares unless immediately after such issuance the total asset value of the Fund’s portfolio is at least 200% of the liquidation value of the outstanding Preferred Shares (i.e., such liquidation value may not exceed 50% of the Fund’s Managed Assets). In addition, the Fund is not permitted to declare any cash dividend or other distribution on its Common Shares unless, at the time of such declaration, the NAV of the Fund’s portfolio (determined after deducting the amount of such dividend or other distribution) is at least 200% of such liquidation value of the Preferred Shares. Normally, holders of Common Shares will elect the directors of the Fund except that the holders of any Preferred Shares will elect two directors. In the event the Fund failed to pay dividends on its Preferred Shares for two years, holders of Preferred Shares would be entitled to elect a majority of the directors until the dividends are paid.

The Fund may be subject to certain restrictions on investments imposed by lenders or by one or more rating agencies that may issue ratings for any senior securities issued by the Fund. Borrowing covenants or rating agency guidelines may impose asset coverage or Fund composition requirements that are more stringent than those imposed on the Fund by the 1940 Act. Since the holders of common stock pay all expenses related to the use of leverage, such use of leverage would create a greater risk of loss for the Fund’s shareholders than if leverage is not used.

The Fund may enter into derivatives or other transactions (e.g., total return swaps) that may provide leverage (other than through borrowings or the issuance of Preferred Shares), but which are not subject to the above noted limitations under the 1940 Act if the Fund earmarks or segregates liquid assets (or enters into offsetting positions) in accordance with applicable SEC regulations and interpretations to cover its obligations under those transactions and instruments. However, pursuant to a rule recently adopted by the SEC, the Fund will become subject to new regulations that govern the use of such derivatives and other transactions during the third quarter of 2022. Once implemented, the new SEC rule will impose, among other things, new limits on the amount of derivatives and other transactions that a fund can enter into and eliminate the asset segregation framework that the Fund currently uses to comply with Section 18 of the 1940 Act.

These transactions entail additional expenses (e.g., transaction costs) which are borne by the Fund. These types of transactions have the potential to increase returns to common shareholders, but they also involve additional risks. This additional leverage will increase the volatility of the Fund’s investment portfolio and could result in larger losses than if the transactions were not entered into. However, to the extent that the Fund enters into offsetting transactions or owns positions covering its obligations, the leveraging effect is expected to be reduced or eliminated.

Tender Option Bonds. The Fund leverages its assets through the use of proceeds received from tender option bond transactions. In a tender option bond transaction, a tender option bond trust (a “TOB Issuer”) is typically established by forming a special purpose trust into which the Fund, or an agent on behalf of the Fund, transfers municipal bonds or other municipal securities. A TOB Issuer typically issues two classes of beneficial interests: short-term floating rate notes (“TOB Floaters”), which are sold to third party investors, and residual interest municipal tender option bonds (“TOB Residuals”), which are generally issued to the Fund. The Fund may invest in both TOB Floaters and TOB Residuals, including TOB Floaters and TOB Residuals issued by the same TOB Issuer. The Fund may not invest more than 5% of its Managed Assets in any single TOB Issuer. The Fund does not currently intend to invest in TOB Residuals issued by a TOB Issuer that was not formed for the Fund, although it reserves the right to do so in the future.

The TOB Issuer receives Municipal Bonds or other municipal securities and then issues TOB Floaters to third party investors and a TOB Residual to the Fund. The Fund is paid the cash (less transaction expenses, which are borne by the Fund and therefore the holders of the Common Shares indirectly) received by the TOB Issuer from the sale of the TOB Floaters and typically will invest the cash in additional Municipal Bonds or other investments permitted by its investment policies. TOB Floaters may have first priority on the cash flow from the securities held by the TOB Issuer and are enhanced with a liquidity support arrangement from a third-party bank or other financial institution (the “liquidity provider”), which allows holders to tender their position at par (plus accrued interest). The Fund, in addition to receiving cash from the sale of the TOB Floaters, also receives the TOB Residual. The TOB Residual provides the Fund with the right to (1) cause the holders of the TOB Floaters to tender their notes to the TOB Issuer at par (plus accrued interest), and (2) acquire the underlying Municipal Bonds or other municipal securities from the TOB Issuer. In addition, all voting rights and decisions to be made with respect to any other rights relating to the underlying securities deposited in the TOB Issuer are passed through to the Fund, as the holder of the TOB Residual. Such a transaction, in effect, creates exposure for the Fund to the entire return of the securities deposited in the TOB Issuer, with a net cash investment by the Fund that is less than the value of the underlying securities deposited in the TOB Issuer. This multiplies the positive or negative impact of the underlying securities’ return within the Fund (thereby creating leverage).

The TOB Issuer may be terminated without the consent of the Fund upon the occurrence of certain events, such as the bankruptcy or default of the issuer of the underlying securities deposited in the TOB Issuer, a substantial downgrade in the credit quality of the issuer of the securities deposited in the TOB Issuer, the inability of the TOB Issuer to obtain liquidity support for the TOB Floaters, a substantial decline in the market value of the underlying securities deposited in the TOB Issuer, or the inability of the sponsor or remarketing agent to remarket any TOB Floaters tendered by holders of the TOB Floaters. In such an event, the TOB Floaters would be redeemed by the TOB Issuer at par (plus accrued interest) out of the proceeds from a sale of the underlying securities deposited in the TOB Issuer. If this happens, the Fund would be entitled to the assets of the TOB Issuer, if any, that remain after the TOB Floaters have been redeemed at par (plus accrued interest). If there are insufficient proceeds from the sale of these securities to redeem all of the TOB Floaters at par (plus accrued interest), the liquidity provider or holders of the TOB Floaters would bear the losses on those securities and there would be no recourse to the Fund’s assets (unless the Fund held a recourse TOB Residual). A recourse TOB Residual is generally a TOB Residual issued by a TOB Issuer in which the TOB Floaters represent greater than 75% of the market value of the securities at the time they are deposited in the TOB Issuer. If the Fund were to invest in a recourse TOB Residual to leverage its portfolio, it would typically be required to enter into an agreement pursuant to which the Fund is required to pay to the liquidity provider the difference between the purchase price of any TOB Floaters put to the liquidity provider by holders of the TOB Floaters and the proceeds realized from the remarketing of those TOB Floaters or the sale of the assets in the TOB Issuer. The Fund currently does not intend to use recourse TOB Residuals to leverage the Fund’s portfolio, but reserves the right to do so depending on future market conditions.

Under accounting rules, securities of the Fund that are deposited into a TOB Issuer are treated as investments of the Fund, and are presented on the Fund’s Schedule of Investments and outstanding TOB Floaters issued by a TOB Issuer are presented as liabilities in the Fund’s Statement of Assets and Liabilities. Interest income from the underlying security is recorded by the Fund on an accrual basis. Interest expense incurred on the TOB Floaters and other expenses related to remarketing, administration and trustee services to a TOB Issuer are reported as expenses of the Fund.

For TOB Floaters, generally, the interest rate earned will be based upon the market rates for municipal securities with maturities or remarketing provisions that are comparable in duration to the periodic interval of the tender option, which may vary from weekly, to monthly, to extended periods of one year or multiple years. Since the option feature has a shorter term than the final maturity or first call date of the underlying securities deposited in the TOB Issuer, the Fund, if it is the holder of the TOB Floaters, relies upon the terms of the agreement with the financial institution furnishing the option as well as the credit strength of that institution. As further assurance of liquidity, the terms of the TOB Issuer provide for a liquidation of the municipal security deposited in the TOB Issuer and the application of the proceeds to pay off the TOB Floaters.

There are inherent risks with respect to investing in a TOB Issuer. These risks include, among others, the bankruptcy or default of the issuer of the securities deposited in the TOB Issuer, a substantial downgrade in the credit quality of the issuer of the securities deposited in the TOB Issuer, the inability of the TOB Issuer to obtain liquidity support for the TOB Floaters, a substantial decline in the market value of the securities deposited in the TOB Issuer, or the inability of the sponsor to remarket any TOB Floaters tendered to it by holders of the TOB Floaters.

Effects of Leverage. The aggregate principal amount of borrowings under the Pershing Facility and the use of proceeds from tender option bond transactions represented approximately 34.55% of Managed Assets as of June 30, 2021. Asset coverage with respect to borrowings under the Pershing Facility was 6,216% and from tender option bond transactions was 304%. Borrowings under Pershing Facility bear interest at the overnight bank funding rate plus 90 basis points for a term of 60 calendar days. As of June 30, 2021, total annual interest rate on the Pershing Facility was 0.98% of the principal amount outstanding, while the average daily weighted interest rate applicable to the leverage attended through the use of tender option bond transactions during the period ending June 30, 2021 was 0.97% of the note obligation outstanding. The total weighted average cost of the leverage outstanding as of June 30, 2021 (inclusive of the Pershing facility and leverage attended through the use of tender option bond transactions) was 0.77% of the principal amount outstanding.

Assuming that the Fund’s leverage costs remain as described above (at an assumed annual cost of 0.77% of the principal amount outstanding) the annual return that the Fund’s portfolio must experience (net of expenses) in order to cover its leverage costs would be 0.27%.

The following table is furnished in response to requirements of the SEC. It is designed to illustrate the effect of leverage on total return on common shares, assuming investment portfolio total returns (comprised of income, net expenses and changes in the value of investments held in the Fund’s portfolio) of -10%, -5%, 0%, 5% and 10%. These assumed investment portfolio returns are hypothetical figures and are not necessarily indicative of what the Fund’s investment portfolio returns will be. In other words, the Fund’s actual returns may be greater or less than those appearing in the table below. The table further reflects the use of leverage representing approximately 34.55% of the Fund’s Managed Assets and the Fund’s assumed annual leverage costs rate of 0.77% of the principal amounts outstanding.

Total return is composed of two elements—the dividends on common shares paid by the Fund (the amount of which is largely determined by the Fund’s net investment income after paying the cost of leverage) and realized and unrealized gains or losses on the value of the securities the Fund owns. As the table shows, leverage generally increases the return to common shareholders when portfolio return is positive or greater than the costs of leverage and decreases return when the portfolio return is negative or less than the costs of leverage.

During the time in which the Fund is using leverage, the amount of the fees paid to the Adviser (and from the Adviser to the Subadviser) for investment management services (and subadvisory services) is higher than if the Fund did not use leverage because the fees paid are calculated based on the Fund’s Managed Assets. This may create a conflict of interest between the Adviser and the Subadviser, on the one hand, and the common shareholders, on the other. Also, because the leverage costs will be borne by the Fund at a specified interest rate, only the Fund’s common shareholders will bear the cost of the Fund’s management fees and other expenses. There can be no assurance that a leveraging strategy will be successful during any period in which it is employed.

Risk Factors

Investing in the Fund involves certain risks relating to its structure and investment objective. You should carefully consider these risk factors, together with all of the other information included in this report, before deciding whether to make an investment in the Fund. An investment in the Fund may not be appropriate for all investors, and an investment in the Common Shares of the Fund should not be considered a complete investment program.

The risks set forth below are not the only risks of the Fund, and the Fund may face other risks that have not yet been identified, which are not currently deemed material or which are not yet predictable. If any of the following risks occur, the Fund’s financial condition and results of operations could be materially adversely affected. In such case, the Fund’s NAV and the trading price of its securities could decline, and you may lose all or part of your investment.

Investment-Related Risks:

With the exception of underlying fund risk (and except as otherwise noted below), the following risks apply to the direct investments the Fund may make, and generally apply to the Fund’s investments in closed-end funds, exchange-traded funds (“ETFs”) and business development companies (“BDCs,” and, together with the Fund’s investments in closed-end funds and ETFs, the “Underlying Funds”). That said, each risk described below may not apply to each Underlying Fund.

Investment and Market Risks. An investment in the Fund is subject to investment risk, including the possible loss of the entire principal amount invested. The value of the Fund or the Underlying Funds, like other market investments, may move up or down, sometimes rapidly and unpredictably. Overall stock market risks may also affect the net asset value of the Fund or the Underlying Funds. Factors such as economic growth and market conditions, interest rate levels and political events affect the securities markets. An investment in the Fund may at any point in time be worth less than the original investment, even after taking into account any reinvestment of dividends and distributions.

Management Risks. The Adviser’s and the Subadviser’s judgments about the attractiveness, value and potential appreciation of a particular asset class or individual security in which the Fund invests may prove to be incorrect and there is no guarantee that the Adviser’s or the Subadviser’s judgment, as applicable, will produce the desired results.

Securities Risks. The value of the Fund or an Underlying Fund may decrease in response to the activities and financial prospects of individual securities in the Fund’s portfolio.

Municipal Bond Risks. The Fund’s indirect and direct investments in Municipal Bonds include certain risks. Municipal Bonds may be affected significantly by the economic, regulatory or political developments affecting the ability of Municipal Bonds issuers to pay interest or repay principal. This risk may be increased during periods of economic downturn or political turmoil. Many municipal securities may be called or redeemed prior to their stated maturity. Issuers of municipal securities might seek protection under bankruptcy laws, causing holders of municipal securities to experience delays in collecting principal and interest or prevent such holders from collecting all principal and interest to which they are entitled. In addition, there may be less information available about Municipal Bond investments than comparable debt and equity investments requiring a greater dependence on the Adviser’s and Sub-Adviser’s analytical abilities.

Certain types of Municipal Bonds may be subject to specific risks. General obligation bonds are obligations involving the credit of an issuer possessing taxing power and are payable from such issuer’s general revenues and not from any particular source, and are subject to risks related to the issuer’s ability to raise tax revenues and ability to maintain an adequate tax base. Revenue bonds are subject to the risk that the underlying facilities may not generate sufficient income to pay expenses and interest costs, lack recourse to ensure payment, or might be subordinate to other debtors. Municipal lease obligations and certificates of participation are subject to the added risk that the governmental lessee will fail to appropriate funds to enable it to meet its payment obligations under the lease. 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. Municipalities and other public authorities issue private activity bonds to finance development of facilities for use by a private enterprise, which is solely responsible for paying the principal and interest on the bond.

Failure of Municipal Bonds to meet regulatory requirements may cause the interest received by the Fund and distributed to shareholders to be taxable, which may apply retroactively to the date of the issuance of the bond. Municipal bonds are also subject to interest rate, credit, and liquidity risk, which are discussed generally under this Risks Factors section.

The current COVID-19 pandemic has significantly stressed the financial resources of many municipalities and other issuers of municipal securities, which may impair their ability to meet their financial obligations and may harm the value or liquidity of the Fund’s investments in municipal securities. In particular, responses by municipalities to the COVID-19 pandemic have caused disruptions in business activities. These and other effects of the COVID-19 pandemic, such as increased unemployment levels, have impacted tax and other revenues of municipalities and other issuers of municipal securities and the financial conditions of such issuers. As a result, there is increased budgetary and financial pressure on municipalities and heightened risk of default or other adverse credit or similar events for issuers of municipal securities, which would adversely impact the Fund’s investments.

State Specific and Industry Risk. While the Fund may not directly invest more than 25% of its Managed Assets in Municipal Bonds in any one industry or in any one state of origin, indirect investments through Underlying Funds might increase the Fund’s exposure to economic, political or regulatory occurrences affecting a particular state or industry.

Puerto Rico Municipal Bond Risks. Municipal obligations issued by the Commonwealth of Puerto Rico or its political subdivisions, agencies, instrumentalities, or public corporations may be affected by economic, market, political, and social conditions in Puerto Rico. Puerto Rico currently is experiencing significant fiscal and economic challenges. These challenges may negatively affect the value of the Fund’s investments in Puerto Rico Municipal Bonds. Legislation or further downgrades or defaults may place additional strain on the Puerto Rico economy and may negatively affect the value, liquidity, and volatility of the Fund’s investments in Puerto Rico Municipal Bonds.

Tobacco Settlement Bond Risks. Tobacco settlement bonds are municipal securities that are backed solely by expected revenues to be derived from lawsuits involving tobacco-related deaths and illnesses, which were settled between certain states and American tobacco companies. Tobacco settlement bonds are secured by an issuing state’s proportionate share an agreement between 46 states and nearly all of the U.S. tobacco manufacturers, under which, the actual amount of future settlement payments by tobacco manufacturers is dependent on many factors, including, but not limited to, annual domestic cigarette shipments, cigarette consumption, increased taxes, inflation, financial capability of tobacco companies, and the possibility of tobacco manufacturer bankruptcy. Payments made by tobacco manufacturers could be negatively impacted if the decrease in tobacco consumption is significantly greater than the forecasted decline.

Credit and Below Investment Grade Securities Risks. Credit risk is the risk that an issuer of a security may be unable or unwilling to make dividend, interest and principal payments when due and the related risk that the value of a security may decline because of concerns about the issuer’s ability or willingness to make such payments. Credit risk may be heightened for the Fund because it and the Underlying Funds may invest in below investment grade securities (“junk” and “high yield” securities). Securities of below investment grade quality are regarded as having speculative characteristics with respect to the issuer’s capacity to pay interest and repay principal, and may be subject to higher price volatility and default risk than investment grade securities of comparable terms and duration. Issuers of lower grade securities may be highly leveraged and may not have available to them more traditional methods of financing. The prices of these lower grade securities are typically more sensitive to negative developments, such as a decline in the issuer’s revenues or a general economic downturn. The secondary market for lower rated securities may not be as liquid as the secondary market for more highly rated securities, a factor which may have an adverse effect on the Fund’s ability to dispose of a particular security.

Interest Rate Risk. Generally, when market interest rates rise, bond prices fall, and vice versa. Interest rate risk is the risk that the municipal securities in the Fund’s portfolio will decline in value because of increases in market interest rates. As interest rates decline, issuers of municipal securities may prepay principal earlier than scheduled, forcing the Fund to reinvest in lower-yielding municipal securities and potentially reducing the Fund’s income. As interest rates increase, slower than expected principal payments may extend the average life of municipal securities, potentially locking in a below-market interest rate and reducing the Fund’s value. In typical market interest rate environments, the prices of longer-term municipal securities generally fluctuate more than prices of shorter-term municipal securities as interest rates change.

LIBOR Risk. Certain of the Fund's or Underlying Funds’ investments, payment obligations and financing terms may be based on floating rates, such as LIBOR, Euro Interbank Offered Rate and other similar types of reference rates (each, a “Reference Rate”). In July of 2017, the head of the UK Financial Conduct Authority ("FCA") announced a desire to phase out the use of LIBOR by the end of 2021. The FCA and ICE Benchmark Administrator have since announced that most LIBOR settings will no longer be published after December 31, 2021 and a majority of U.S. dollar LIBOR settings will cease publication after June 30, 2023. The U.S. Federal Reserve, based on the recommendations of the New York Federal Reserve's Alternative Reference Rate Committee (comprised of major derivative market participants and their regulators), has begun publishing Secured Overnight Financial Rate Data ("SOFR") that is intended to replace U.S. dollar LIBOR. Proposals for alternative reference rates for other currencies have also been announced or have already begun publication. Markets are slowly developing in response to these new reference rates. Uncertainty related to the liquidity impact of the change in rates, and how to appropriately adjust these rates at the time of transition, poses risks for the Fund. The expected discontinuation of LIBOR could have a significant impact on the financial markets in general and may also present heightened risk to market participants, including public companies, investment advisers, investment companies, and broker-dealers. The risks associated with this discontinuation and transition will be exacerbated if the work necessary to effect an orderly transition to an alternative reference rate is not completed in a timely manner. Accordingly, it is difficult to predict the full impact of the transition away from LIBOR on the Fund or the Underlying Funds until new reference rates and fallbacks for both legacy and new instruments and contracts are commercially accepted and market practices become settled. The inclusion of LIBOR Risk under the Risk Factors section is a material change since the prior disclosure date.

Inflation/Deflation Risk. Inflation risk is the risk that the value of assets or income from investments will be worth less in the future as inflation decreases the value of money. As inflation increases, the real value of the Common Shares and distributions can decline. Deflation risk is the risk that prices throughout the economy decline over time– the opposite of inflation. Deflation may have an adverse effect on the creditworthiness of issuers and may make issuer defaults more likely, which may result in a decline in the value of the Fund’s portfolio.

Tactical Municipal Closed-End Fund Strategy Risk. The Fund invests in closed-end funds as a principal part of the Tactical Municipal Closed-End Fund Strategy. The Fund may invest in shares of closed-end funds that are trading at a discount to NAV or at a premium to NAV. There can be no assurance that the market discount on shares of any closed-end fund purchased by the Fund will ever decrease.

In fact, it is possible that this market discount may increase and the Fund may suffer realized or unrealized capital losses due to further decline in the market price of the securities of such closed-end funds, thereby adversely affecting the NAV of the Fund’s Common Shares. Similarly, there can be no assurance that any shares of a closed-end fund purchased by the Fund at a premium will continue to trade at a premium or that the premium will not decrease subsequent to a purchase of such shares by the Fund.

Underlying Fund Risks. Because the Fund invests in Underlying Funds, the risks associated with investing in the Fund are closely related to the risks associated with the securities and other investments held by the Underlying Funds. The ability of the Fund to achieve its investment objective will depend upon the ability of the Underlying Funds to achieve their investment objectives. There can be no assurance that the investment objective of any Underlying Fund will be achieved.

The Fund’s net asset value will fluctuate in response to changes in the net asset values of the Underlying Funds in which it invests and will be particularly sensitive to the risks associated with each of the Underlying Funds. Shareholders will bear additional layers of fees and expenses with respect to the Fund’s investments in Underlying Funds because each of the Fund and the Underlying Fund will charge fees and incur separate expenses, which may be magnified if the Underlying Funds use leverage.

Defaulted and Distressed Securities Risks. The Fund and the Underlying Funds may invest in defaulted and distressed securities. Defaulted or distressed issuers may be insolvent, in bankruptcy or undergoing some other form of financial restructuring. In the event of a default, the Fund or an Underlying Fund may incur additional expenses to seek recovery. The repayment of defaulted bonds is subject to significant uncertainties, may be delayed, or there may be partial or no recovery of repayment. There is often a time lag between when the Fund and an Underlying Fund makes an investment and when the Fund and the Underlying Fund realizes the value of the investment.

Illiquid Securities Risks. The Fund and the Underlying Funds may invest in illiquid securities. It may not be possible to sell or otherwise dispose of illiquid securities both at the price and within the time period deemed desirable by a fund. Illiquid securities also may be difficult to value or be more volatile investments.

Valuation Risk. There is no central place or national exchange for fixed-income securities trading. Uncertainties in the conditions of the financial market, unreliable reference data, lack of transparency and inconsistency of valuation models and processes may lead to inaccurate asset pricing. As a result, the Fund may be subject to risk that when a fixed-income security is sold in the market, the amount received by the Fund is less than the value of such fixed-income security carried on the Fund’s books.

Tender Option Bonds Risks. The Fund’s participation in tender option bond transactions may reduce the Fund’s returns and/or increase volatility. Investments in tender option bond transactions expose the Fund to counterparty risk and leverage risk. An investment in a tender option bond transaction typically will involve greater risk than an investment in a municipal fixed rate security, including the risk of loss of principal. Distributions on TOB Residuals will bear an inverse relationship to short-term municipal security interest rates. Distributions on TOB Residuals paid to the Fund will be reduced or, in the extreme, eliminated as short-term municipal interest rates rise and will increase when short-term municipal interest rates fall. The value of TOB Residuals may decline rapidly in times of rising interest rates.

The Fund’s use of proceeds received from tender option bond transactions will create economic leverage, creating an opportunity for increased income and returns, but will also create the possibility that long-term returns will be diminished if the cost of the TOB Floaters exceeds the return on the securities deposited in the TOB Issuer. If the income and gains earned on Municipal Bonds deposited in a TOB Issuer that issues TOB Residuals to the Fund are greater than the payments due on the TOB Floaters, the Fund’s returns will be greater than if it had not invested in the TOB Residuals.

Insurance Risks. The Fund may purchase Municipal Bonds that are secured by insurance, bank credit agreements or escrow accounts. The insurance feature of a Municipal Bond does not guarantee the full payment of principal and interest through the life of an insured obligation, the market value of the insured obligation or the NAV of the shares represented by such insured obligation.

Tax Risks. Future laws, regulations, rulings or court decisions may cause interest on municipal securities to be subject, directly or indirectly, to U.S. federal income taxation; interest on state municipal securities to be subject to state or local income taxation; the value of state municipal securities to be subject to state or local intangible personal property tax; or may otherwise prevent the Fund from realizing the full current benefit of the tax-exempt status of such securities. Any such change could also affect the market price of such securities, and thus the value of an investment in the Fund.

Derivatives Risks. The Fund and the Underlying Funds may enter into derivatives which have risks different from those associated with the Fund’s other investments. Generally, a derivative is a financial contract, the value of which depends upon, or is derived from, the value of an underlying asset, reference rate, or index, and may relate to individual debt or equity instruments, interest rates, currencies or currency exchange rates, commodities, related indexes, and other assets.

Derivatives may entail investment exposures that are greater than their cost would suggest, meaning that a small investment in a derivative could have a large potential impact on the performance of the Fund or an Underlying Fund. The Fund or an Underlying Fund could experience a loss if derivatives do not perform as anticipated, if they are not correlated with the performance of other investments which they are used to hedge or if the fund is unable to liquidate a position because of an illiquid secondary market. Except with respect to the Fund’s investments in total return swaps, the Fund expects its use of derivative instruments will be for hedging purposes. When used for speculative purposes, derivatives will produce enhanced investment exposure, which will magnify gains and losses. The Fund and the Underlying Funds also will be subject to credit risk with respect to the counterparties to the derivatives contracts purchased by such fund. If a counterparty becomes bankrupt or otherwise fails to perform its obligations under a derivative contract, the Fund or an Underlying Fund may obtain only a limited recovery or may obtain no recovery in such circumstances.

Options and Futures Risks. Options and futures contracts may be more volatile than investments made directly in the underlying securities, involve additional costs, and may involve a small initial investment relative to the risk assumed. In addition, futures and options markets could be illiquid in some circumstances and certain over-the-counter options could have no markets. As a result, in certain markets, a fund may not be able to close out a transaction without incurring substantial losses. Although a fund’s use of futures and options transactions for hedging should tend to minimize the risk of loss due to a decline in the value of the hedged position, at the same time, it will tend to limit any potential gain to a fund that might result from an increase in value of the position.

Market Disruption and Geopolitical Risks. The Fund and Underlying Funds may be adversely affected by uncertainties and events around the world, such as terrorism, political developments, and changes in government policies, taxation, restrictions on foreign investment and currency repatriation, currency fluctuations and other developments in the laws and regulations of the countries in which they are invested. Assets of issuers, including those held in the Fund’s or an Underlying Fund’s portfolio, could be direct targets, or indirect casualties, of an act of terrorism.

Pandemic Risk. Beginning in the first quarter of 2020, financial markets in the United States and around the world experienced extreme and in many cases unprecedented volatility and severe losses due to the global pandemic caused by COVID-19, a novel coronavirus. The pandemic has resulted in a wide range of social and economic disruptions, including closed borders, voluntary or compelled quarantines of large populations, stressed healthcare systems, reduced or prohibited domestic or international travel, supply chain disruptions, and so-called “stay-at-home” orders throughout much of the United States and many other countries. The fall-out from these disruptions has included the rapid closure of businesses deemed “non-essential” by federal, state, or local governments and rapidly increasing unemployment, as well as greatly reduced liquidity for certain instruments at times. Some sectors of the economy and individual issuers have experienced particularly large losses. Such disruptions may continue for an extended period of time or reoccur in the future to a similar or greater extent. In response, the U.S. government and the Federal Reserve have taken extraordinary actions to support the domestic economy and financial markets, resulting in very low interest rates and in some cases negative yields. Although vaccines for COVID- 19 are becoming more widely available, it is unknown how long circumstances related to the pandemic will persist, whether they will reoccur in the future, whether efforts to support the economy and financial markets will be successful, and what additional implications may follow from the pandemic. The impact of these events and other epidemics or pandemics in the future could adversely affect Fund performance.

Swap Risks. The Fund and the Underlying Funds may enter into various swap agreements. Swap agreements are subject to interest rate risks; credit risks; the risk that the counterparty to the swap will default on its obligation to pay the Fund and the risk that the Fund will not be able to meet its obligations to pay the counterparty to the swap. In addition, there is the risk that a swap may be terminated by the Fund or the counterparty in accordance with its terms. Each of these could cause the Fund to incur losses and fail to obtain its investment objective.

Short Sale Risks. Short sales are expected to be utilized by the Fund, if at all, for hedging purposes. A short sale is a transaction in which a fund sells a security it does not own in anticipation that the market price of that security will decline. Positions in shorted securities are speculative and riskier than long positions (purchases) in securities because the maximum sustainable loss on a security purchased is limited to the amount paid for the security plus the transaction costs, whereas there is no maximum attainable price of the shorted security. Therefore, in theory, securities sold short have unlimited risk and may also result in higher transaction costs and higher taxes.

Rating Agency Risk. Ratings represent an NRSRO's opinion regarding the quality of the security and are not a guarantee of quality. NRSROs may fail to make timely credit ratings in response to subsequent events. In addition, NRSROs are subject to an inherent conflict of interest because they are often compensated by the same issuers whose securities they grade.

United States Credit Rating Downgrade Risk. On August 5, 2011, S&P lowered its long-term sovereign credit rating on the United States to “AA+” from “AAA.” In general, a lower rating could increase the volatility in both stock and bond markets, result in higher interest rates and lower Treasury prices and increase the costs of all types of debt.

Legislation and Regulatory Risks. At any time, legislation or additional regulations may be enacted that could negatively affect the assets of the Fund, securities held by the Fund or the issuers of such securities. Fund shareholders may incur increased costs resulting from such legislation or additional regulation. There can be no assurance that future legislation, regulation or deregulation will not have a material adverse effect on the Fund or will not impair the ability of the Fund to achieve its investment objective.

On October 28, 2020, the SEC adopted new regulations governing the use of derivatives by registered investment companies (“Rule 18f-4”). The Fund will be required to implement and comply with Rule 18f-4 by the third quarter of 2022. Once implemented, Rule 18f-4 will impose new limits on the amount of derivatives, short sales, and tender option bond transactions that the Fund can enter into; eliminate the asset segregation framework the Fund currently uses to comply with Section 18 of the 1940 Act; treat certain derivatives as senior securities so that a failure to comply with the limits might be alleged by a regulator to be a statutory violation; and potentially require the Fund to establish and maintain a comprehensive derivatives risk management program and appoint a derivatives risk manager. The extent of the impact of such new regulations on the Fund, including the ability of the Fund to continue to utilize derivatives, short sales and tender option bond transactions in an amount similar to its initial use of such transactions, remains uncertain as of the date of this report.

Defensive Measures. The Fund may invest up to 100% of its assets in cash, cash equivalents and short-term investments as a defensive measure in response to adverse market conditions or opportunistically at the discretion of the Adviser or Subadviser. During these periods, the Fund may not be pursuing its investment objectives.

Structural Risks:

Market Discount. Common stock of closed-end funds frequently trades at a discount from its net asset value. This risk may be greater for investors selling their shares in a relatively short period of time after completion of the initial offering. The Fund’s Common Shares may trade at a price that is less than the initial offering price. This risk would also apply to the Fund’s investments in closed-end funds.

Limited Term and Eligible Tender Offer Risk. The Fund is scheduled to terminate on or around July 25, 2031 (the “Termination Date”) unless it is converted to a perpetual fund, as described below. The Fund’s investment objectives and policies are not designed to seek to return to investors their initial investment and such investors and investors that purchase shares of the Fund may receive more or less than their original investment.

The Board may, but is not required to, cause the Fund to conduct a tender offer to all common shareholders at a price equal to the NAV (an “Eligible Tender Offer”). If the Fund conducts an Eligible Tender Offer, there can be no assurance that the Fund’s net assets would not fall below $100 million (the “Termination Threshold”), in which case the Eligible Tender Offer will be terminated, and the Fund will terminate on or before the Termination Date (subject to possible extensions). If the Fund’s net assets are equal or greater than the Termination Threshold, the Fund will have a perpetual existence upon the affirmative vote of a majority of the Board, without shareholder approval.

An Eligible Tender Offer or liquidation may require the Fund to sell securities when it otherwise would not, or at reduced prices, leading to losses for the Fund and increased transaction expenses. Thereafter, remaining shareholders may only be able to sell their shares at a discount to NAV. The Adviser may have a conflict of interest in recommending that the Fund have a perpetual existence.

The potential required sale of portfolio securities, purchase of tendered shares in an Eligible Tender Offer, and/or potential liquidation of the Fund may also have adverse tax consequences for the Fund and shareholders. In addition, the completion of an Eligible Tender Offer may cause disruptions and changes in the Fund’s investment portfolio, increase the proportional burden of the Fund’s expenses on the remaining shareholders, and adversely impact the secondary market trading of such shares.

Investment Style Risk. The Fund is managed by allocating the Fund’s assets to two different strategies, which cause the Fund to underperform funds that do not limit their investments to these two strategies during periods when these strategies underperform other types of investments.

Multi-Manager Risk. The Adviser and the Subadviser’s investment styles may not always be complementary, which could adversely affect the performance of the Fund. The Adviser and the Subadviser may, at any time, take positions that in effect may be opposite of positions taken by each other, incurring brokerage and other transaction costs without accomplishing any net investment results. The multi-manager approach could increase the Fund’s portfolio turnover rates, which may result in higher trading costs and tax consequences associated with portfolio turnover that may adversely affect the Fund’s performance. Further, if the Subadviser is not retained, Fund performance will become dependent on the Adviser or a new subadviser successfully implementing the municipal bond income strategy, which might have adverse effect on an investment in the Fund.

Asset Allocation Risk. To the extent that the Adviser’s asset allocation between the Fund’s principal investment strategies may fail to produce the intended result, the Fund’s return may suffer. Additionally, the potentially active asset allocation style of the Fund may lead to changing allocations over time and represent a risk to investors who target fixed asset allocations.

Leverage Risks. Leverage is a speculative technique that exposes the Fund to greater risk and increased costs than if it were not implemented. Increases and decreases in the value of the Fund’s portfolio will be magnified when the Fund uses leverage. As a result, leverage may cause greater changes in the Fund’s net asset value. The leverage costs may be greater than the Fund’s return on the underlying investments made from the proceeds of leverage. The Fund’s leveraging strategy may not be successful. Leverage risk would also apply to the Fund’s investments in Underlying Funds to the extent an Underlying Fund uses leverage. To the extent the Fund uses leverage and invests in Underlying Funds that also use leverage, the risks associated with leverage will be magnified, potentially significantly.

Portfolio Turnover Risk. The Fund’s annual portfolio turnover rate may vary greatly from year to year. High portfolio turnover may result in the realization of net short-term capital gains by the Fund which, when distributed to shareholders, will be taxable as ordinary income. In addition, a higher portfolio turnover rate results in correspondingly greater brokerage commissions and other transactional expenses that are borne by the Fund. Portfolio turnover rate is not considered a limiting factor in the execution of investment decisions for the Fund.

Potential Conflicts of Interest Risk. The Adviser and the Subadviser each manages and/or advises other investment funds or accounts with the same or similar investment objectives and strategies as the Fund, and, as a result may face conflict of interests regarding the implementation of the Fund’s strategy and allocation between funds and accounts. This may limit the Fund’s ability to take full advantage of the investment opportunity or affect the market price of the investment. Each party may also have incentives to favor one account over another due to different fees paid to such accounts. While each party has adopted policies and procedures that address these potential conflicts of interest, there is no guarantee that the policies will be successful in mitigating the conflicts of interest that arise. In addition, the Fund’s use of leverage will increase the amount of the fees paid to the Adviser and Subadviser, creating a financial incentive for the Adviser to leverage the Fund.

Stockholder Activism. The Fund may in the future become the target of stockholder activism. Stockholder activism could result in substantial costs and divert management’s and the Board’s attention and resources from its business. Also, the Fund may be required to incur significant legal and other expenses related to any activist stockholder matters. Further, the Fund’s stock price could be subject to significant fluctuation or otherwise be adversely affected by the events, risks and uncertainties of any stockholder activism.

Cybersecurity Risk. A cybersecurity breach may disrupt the business operations of the Fund or its service providers. A breach may allow an unauthorized party to gain access to Fund assets, customer data, or proprietary information, or cause the Fund and/or its service providers to suffer data corruption or lose operational functionality.

Risks Associated with Additional Offerings. There are risks associated with offerings of additional common or preferred shares of the Fund. The voting power of current shareholders will be diluted to the extent that current shareholders do not purchase shares in any future offerings of shares or do not purchase sufficient shares to maintain their percentage interest. In addition, the sale of shares in an offering may have an adverse effect on prices in the secondary market for the Fund’s shares by increasing the number of shares available, which may put downward pressure on the market price of the Fund’s Shares. These sales also might make it more difficult for the Fund to sell additional equity securities in the future at a time and price the Fund deems appropriate.

In the event any additional series of fixed rate preferred shares are issued and such shares are intended to be listed on an exchange, prior application will have been made to list such shares. During an initial period, which is not expected to exceed 30 days after the date of its initial issuance, such shares may not be listed on any securities exchange. During such period, the underwriters may make a market in such shares, although they will have no obligation to do so. Consequently, an investment in such shares may be illiquid during such period. Fixed rate preferred shares may trade at a premium to or discount from liquidation value.

There are risks associated with an offering of Rights (in addition to the risks discussed herein related to the offering of shares and preferred shares). Shareholders who do not exercise their rights may, at the completion of such an offering, own a smaller proportional interest in the Fund than if they exercised their rights. As a result of such an offering, a shareholder may experience dilution in net asset value per share if the subscription price per share is below the net asset value per share on the expiration date. In addition to the economic dilution described above, if a shareholder does not exercise all of their Rights, the shareholder will incur voting dilution as a result of the Rights offering. This voting dilution will occur because the shareholder will own a smaller proportionate interest in the Fund after the rights offering than prior to the Rights offering.

There is a risk that changes in market conditions may result in the underlying common shares or preferred shares purchasable upon exercise of Rights being less attractive to investors at the conclusion of the subscription period. This may reduce or eliminate the value of the Rights. If investors exercise only a portion of the rights, the number of shares issued may be reduced, and the shares may trade at less favorable prices than larger offerings for similar securities. Rights issued by the Fund may be transferable or non-transferable rights.

Secondary Market for the Common Shares. The issuance of shares of the Fund through the Fund’s dividend reinvestment plan (“Plan”) may have an adverse effect on the secondary market for the Fund’s shares. The increase in the number of outstanding shares resulting from the issuances pursuant to the Plan and the discount to the market price at which such shares may be issued, may put downward pressure on the market price for the Common Shares. When the shares are trading at a premium, the Fund may also issue shares that may be sold through private transactions effected on the NYSE or through broker-dealers. The increase in the number of outstanding shares resulting from these offerings may put downward pressure on the market price for such shares.

Anti-Takeover Provisions. Maryland law and the Fund’s Charter and Bylaws include provisions that could limit the ability of other entities or persons to acquire control of the Fund or to convert the Fund to open-end status, including the adoption of a staggered Board of Directors and the supermajority voting requirements. These provisions could deprive the common shareholders of opportunities to sell their common shares at a premium over the then current market price of the common shares or at NAV.
