The “Management Fees” shown in the fee table are higher than the contractual management fee rates because the “Management Fees” in the table are calculated as a percentage of the Fund’s net assets applicable to Common Shares, rather than the Fund’s Managed Assets. Managed Assets includes assets attributable to leverage. The management fee consists of a fund-level fee and complex-level fee. Restated to reflect current operating levels as of March 31, 2026, the annualized Fund-level fee was 0.7734% of Managed Assets or 1.0974% of Net Assets Attributable to Common Shares and the annualized complex-level fee was 0.1563% of Managed Assets or 0.2191% of Net Assets Attributable to Common Shares. See “Management of the Fund—Investment Management and Sub-Advisory Agreements” for a complete discussion of how the Management Fee is calculated.

⁽³⁾

Interest and Other Related Expenses have been restated and annualized to reflect current outstanding leverage amounts. Interest and Other Related Expenses are estimated to reflect actual leverage outstanding as of March 31, 2026 and estimated interest and associated costs. Actual Interest and Other Related Expenses incurred in the future may be higher or lower. If short-term market interest rates rise in the future, and if the Fund continues to maintain leverage the cost of which is tied to short-term interest rates, the Fund’s interest expenses on its borrowings can be expected to rise in tandem. The Fund’s use of leverage will increase the amount of management fees paid to Nuveen Fund Advisors and Nuveen Asset Management.

⁽⁴⁾

Other Expenses are estimated for the current fiscal year based on the Fund’s fees and expenses for the fiscal year ended March 31, 2026. Expenses attributable to the Fund’s investments, if any, in other investment companies are currently estimated not to exceed 0.01%. See “Portfolio Composition and Other Information—Other Investment Companies” in the SAI.

⁽⁵⁾

Nuveen Fund Advisors has agreed to waive fees and/or reimburse expenses through July 31, 2028, so that the total annual operating expenses of the Fund (excluding any distribution and/or service fees that may be applicable to a particular class of shares, issuance and dividend costs of Preferred Shares that may be issued by the Fund, interest expenses, taxes, acquired fund fees and expenses, fees incurred in acquiring and disposing of portfolio securities, litigation expenses and extraordinary expenses) do not exceed 1.05% of the average daily Managed Assets of any class of Fund shares. This expense limitation may be terminated or modified prior to that date only with the approval of the Board of Trustees.

Investment Objectives and Practices [Text Block]

Investment Objectives

The Fund’s primary investment objective is to provide a high level of current income exempt from regular U.S. federal income tax. Capital appreciation is a secondary investment objective when consistent with the Fund’s primary investment objective. However, there can be no assurance that the Fund will achieve either of its investment objectives or that the Fund’s investment strategies will be successful. See “Risks.” The Fund’s investment objectives may be changed by the Board of Trustees upon 60 days’ prior written notice to shareholders.

Fund Strategies

The Fund’s portfolio is actively managed to identify and capitalize on high yield municipal securities. Nuveen Asset Management uses a research-driven approach that seeks attractive income exempt from regular U.S. federal income taxes by identifying and capitalizing on opportunities in high yield municipal securities. The Fund invests in below investment grade bonds that Nuveen Asset Management believes may offer the potential for attractive total returns, even after taking into account the significant risk (relative to higher quality securities) that these securities typically present.

The Fund may also invest in special situations municipal securities that Nuveen Asset Management believes may offer the potential for attractive total returns, even after taking into account the significant risk (relative to higher quality securities) that these securities typically present. Special situations municipal securities may offer illiquidity and complexity premiums, which may create significant investment opportunity for the Fund.

The Fund may also use certain hedging techniques to reduce exposure of the portfolio to adverse business or market conditions. See “—Other Policies” and “Risks—Portfolio Level Risks—Hedging Risk” below.

As an “interval fund”, the Fund provides Common Shareholders periodic liquidity. See “Periodic Repurchase Offers” below. Nuveen Fund Advisors believes the Fund’s “interval fund” structure may provide greater income and total return potential as compared to a traditional high yield municipal mutual fund. Without the potential disruption of outflows from daily liquidity, Nuveen Asset Management may capture illiquidity premiums often unavailable to individual retail investors through more liquid investment vehicles such as mutual funds. In addition, Nuveen Fund Advisors believes that the Fund’s interval structure allows more flexibility to assume larger position sizes; enables a greater allocation to less-illiquid municipal securities; and provides the Fund the opportunity to realize the maximum long-term value of certain special situations within the municipal market such as work-outs (a privately negotiated, mutual agreement between the Fund and the issuer or another party with respect to securities in default or involved in bankruptcy or insolvency proceedings).

Portfolio Contents

The Fund’s portfolio will be composed principally of the following investments. More detailed information about the Fund’s portfolio investments are contained in the SAI under “Portfolio Composition and Other Information.”

Municipal Securities

Municipal securities 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 securities 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, or 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 may also purchase municipal securities that represent lease obligations, municipal notes, pre-refunded municipal bonds, private activity bonds, tender option bonds and other forms of municipal bonds and securities.

The municipal securities in which the Fund will invest are generally issued by states, cities and local authorities and certain possessions and territories of the United States (such as Puerto Rico and Guam), and pay interest that, in the opinion of bond counsel to the issuer (or on the basis of other authority believed by Nuveen Asset Management to be reliable), is exempt from regular U.S. federal income tax, although the interest may be subject to the federal alternative minimum tax. Municipal securities issued by Puerto Rico involve specific risks. See “Risks—Portfolio Level Risks—Puerto Rico Municipal Securities Market Risk” below.

The yields on municipal securities depend 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 issue. The market value of municipal securities will vary with changes in interest rate levels and as a result of changing evaluations of the ability of their issuers to meet interest and principal payments.

The Fund may invest in “tobacco settlement bonds.” Tobacco settlement bonds are municipal securities that are secured or payable solely from the collateralization of the proceeds from class action or other litigation against the tobacco industry. Investments in tobacco settlement bonds are subject to risks. See “Risks—Portfolio Level Risks—Tobacco Settlement Bond Risk” below.

Municipal Leases and Certificates of Participation. The Fund also may purchase municipal securities that represent lease obligations and certificates of participation in such leases. These carry special risks because the issuer of the securities may not be obligated to appropriate money annually to make payments under the lease. A municipal lease is an obligation in the form of a lease or installment purchase which is issued by a state or local government to acquire equipment and facilities. Income from such obligations is generally exempt from U.S. federal income tax, as well as from state and local taxes in the state of issuance. Leases and installment purchase or conditional sale contracts (which normally provide for title to the leased asset to pass eventually to the governmental issuer) have evolved as a means for governmental issuers to acquire property and equipment without meeting the constitutional and statutory requirements for the issuance of debt. The debt issuance limitations are deemed to be inapplicable because of the inclusion in many leases or contracts of “non-appropriation” clauses that relieve the governmental issuer of any obligation to make future payments under the lease or contract unless money is appropriated for such purpose by the appropriate legislative body on a yearly or other periodic basis. In addition, such leases or contracts may be subject to the temporary abatement of payments in the event the issuer is prevented from maintaining occupancy of the leased premises or utilizing the leased equipment or facilities. Although the obligations may be secured by the leased equipment or facilities, the disposition of the property in the event of non-appropriation or foreclosure might prove difficult, time consuming and costly, and result in a delay in recovering, or the failure to recover fully, the Fund’s original investment. To the extent that the Fund invests in unrated municipal leases or participates in such leases, the credit quality rating and risk of cancellation of such unrated leases will be monitored on an ongoing basis. In order to reduce this risk, the Fund will only purchase municipal securities representing lease obligations where Nuveen Asset Management believes the issuer has a strong incentive to continue making appropriations until maturity.

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. Such certificates provide the Fund with the right to a pro rata undivided interest in the underlying municipal securities. 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 municipal securities, plus accrued interest.

Municipal Notes. Municipal securities in the form of notes generally are used to provide for short-term capital needs, in anticipation of an issuer’s receipt of other revenues or financing, and typically have maturities of up to three years. Such instruments may include tax anticipation notes, revenue anticipation notes, bond anticipation notes, tax and revenue anticipation notes and construction loan notes. Tax anticipation notes are issued to finance the working capital needs of governments. Generally, they are issued in anticipation of various tax revenues, such as income, sales, property, use and business taxes, and are payable from these specific future taxes. Revenue anticipation notes are issued in expectation of receipt of other kinds of revenue, such as federal revenues available under federal revenue sharing programs. Bond anticipation notes are issued to provide interim financing until long-term bond financing can be arranged. In most cases, the long-term bonds then provide the funds needed for repayment of the bond anticipation notes. Tax and revenue anticipation notes combine the funding sources of both tax anticipation notes and revenue anticipation notes. Construction loan notes are sold to provide construction financing. Mortgage notes insured by the Federal Housing Authority secure these notes; however, the proceeds from the insurance may be less than the economic equivalent of the payment of principal and interest on the mortgage note if there has been a default. The anticipated revenues from taxes, grants or bond financing generally secure the obligations of an issuer of municipal notes. An investment in such instruments, however, presents a risk that the anticipated revenues will not be received or that such revenues will be insufficient to satisfy the issuer’s payment obligations under the notes or that refinancing will be otherwise unavailable.

Pre-Refunded Municipal Securities. The principal of, and interest on, pre-refunded municipal securities are no longer paid from the original revenue source for the securities. Instead, the source of such payments is typically an escrow fund consisting of U.S. government securities. The assets in the escrow fund are derived from the proceeds of refunding bonds issued by the same issuer as the pre-refunded municipal securities. Issuers of municipal securities use this advance refunding technique to obtain more favorable terms with respect to securities that are not yet subject to call or redemption by the issuer. For example, advance refunding enables an issuer to refinance debt at lower market interest rates, restructure debt to improve cash flow or eliminate restrictive covenants in the indenture or other governing instrument for the pre-refunded municipal securities. However, except for a change in the revenue source from which principal and interest payments are made, the pre-refunded municipal securities remain outstanding on their original terms until they mature or are redeemed by the issuer. The 2017 Tax Cuts and Jobs Act repealed the exclusion from gross income for interest on pre-refunded municipal securities effective for such bonds issued after December 31, 2017.

Private Activity Bonds. Private activity bonds, formerly referred to as industrial development 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, equipment, repair or improvement of privately operated industrial or commercial facilities, may constitute municipal securities, although the current federal tax laws place substantial limitations on the size of such issues. Under current law, a significant portion of the private activity bond market is comprised of AMT Bonds. The Fund’s distributions of its interest income from private activity bonds may subject certain investors to the federal alternative minimum tax. See “Tax Matters.”

Inverse Floating Rate Securities. The Fund may invest in inverse floating rate securities. Inverse floating rate securities are securities whose interest rates bear an inverse relationship to the interest rate on another security or the value of an index. Generally, inverse floating rate securities represent beneficial interests in a special purpose trust, commonly referred to as a “tender option bond trust” (“TOB trust”), that holds municipal bonds. The TOB trust typically sells two classes of beneficial interests or securities: floating rate securities (sometimes referred to as short-term floaters or tender option bonds (“TOBs”)), and inverse floating rate securities (sometimes referred to as inverse floaters). Both classes of beneficial interests are represented by certificates or receipts. The floating rate securities have first priority on the cash flow from the municipal bonds held by the TOB trust. In this structure, the floating rate security holders have the option, at periodic short-term intervals, to tender their securities to the trust for purchase and to receive the face value thereof plus accrued interest. The obligation of the trust to repurchase tendered securities is supported by a remarketing agent and by a liquidity provider. As consideration for providing this support, the remarketing agent and the liquidity provider receive periodic fees. The holder of the short-term floater effectively holds a demand obligation that bears interest at the prevailing short-term, tax-exempt rate. However, the trust is not obligated to purchase tendered short-term floaters in the event of certain defaults with respect to the underlying municipal bonds or a significant downgrade in the credit rating assigned to the bond issuer.

As the holder of an inverse floating rate investment, the Fund receives the residual cash flow from the TOB trust. Because the holder of the short-term floater is generally assured liquidity at the face value of the security plus accrued interest, the holder of the inverse floater assumes the interest rate cash flow risk and the market value risk associated with the municipal bond deposited into the TOB trust. The volatility of the interest cash flow and the residual market value will vary with the degree to which the trust is leveraged. This is expressed in the ratio of the total face value of the short-term floaters to the value of the inverse floaters that are issued by the TOB trust. All voting rights and decisions to be made with respect to any other rights relating to the municipal bonds held in the TOB trust are passed through, pro rata, to the holders of the short-term floaters and to the Fund as the holder of the associated inverse floaters.

Because any increases in the interest rate on the short-term floaters issued by a TOB trust would reduce the residual interest paid on the associated inverse floaters, and because fluctuations in the value of the municipal bond deposited in the TOB trust would only affect the value of the inverse floater and not the value of the short-term floater issued by the trust so long as the value of the municipal bond held by the trust exceeded the face amount of short-term floaters outstanding, the value of inverse floaters is generally more volatile than that of an otherwise comparable municipal bond held on an unleveraged basis outside a TOB trust. Inverse floaters generally will underperform the market of fixed-rate bonds in a rising interest rate environment (i.e., when bond values are falling), but will tend to outperform the market of fixed-rate bonds when interest rates decline or remain relatively stable. Although volatile in value and return, inverse floaters typically offer the potential for yields higher than those available on fixed-rate bonds with comparable credit quality, coupon, call provisions and maturity. Inverse floaters have varying degrees of liquidity or illiquidity based primarily upon the inverse floater holder’s ability to sell the underlying bonds deposited in the TOB trust at an attractive price.

The Fund may invest in inverse floating rate securities issued by TOB trusts in which the liquidity providers have recourse to the Fund pursuant to a separate shortfall and forbearance agreement. Such an agreement would require the Fund to reimburse the liquidity provider, among other circumstances, upon termination of the TOB trust for the difference between the liquidation value of the bonds held in the trust and the principal amount and accrued interest due to the holders of floating rate securities issued by the trust. The Fund will enter into such a recourse agreement (1) when the liquidity provider requires such a recourse agreement because the level of leverage in the TOB trust exceeds the level that the liquidity provider is willing to support absent such an agreement; and/or (2) to seek to prevent the liquidity provider from collapsing the trust in the event the municipal bond held in the trust has declined in value to the point where it may cease to exceed the face amount of outstanding short-term floaters. In an instance where the Fund has entered such a recourse agreement, the Fund may suffer a loss that exceeds the amount of its original investment in the inverse floating rate securities; such loss could be as great as that original investment amount plus the face amount of the floating rate securities issued by the trust plus accrued interest thereon.

The Fund may invest in both inverse floating rate securities and floating rate securities (as discussed below) issued by the same TOB trust.

Floating Rate Securities. The Fund may also invest in short-term floating rate securities, as described above, issued by TOB trusts. 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 other periods of up to one year. Since the tender option feature provides a shorter term than the final maturity or first call date of the underlying municipal bond deposited in the trust, the Fund, as the holder of the floating rate securities, relies upon the terms of the remarketing and liquidity agreements with the financial institution that acts as remarketing agent and/or liquidity provider as well as the credit strength of that institution. As further assurance of liquidity, the terms of the TOB trust provide for a liquidation of the municipal bond deposited in the trust and the application of the proceeds to pay off the floating rate securities. The TOB trusts that are organized to issue both short-term floating rate securities and inverse floaters generally include liquidation triggers to protect the investor in the floating rate securities.

Special Taxing Districts. Special taxing districts are organized to plan and finance infrastructure developments to induce residential, commercial and industrial growth and redevelopment. The bond financing methods such as tax increment finance, tax assessment, special services district and Mello-Roos bonds, are generally payable solely from taxes or other revenues attributable to the specific projects financed by the bonds without recourse to the credit or taxing power of related or overlapping municipalities. They often are exposed to real estate development-related risks and can have more taxpayer concentration risk than general tax-supported bonds, such as general obligation bonds. Further, the fees, special taxes, or tax allocations and other revenues that are established to secure such financings are generally limited as to the rate or amount that may be levied or assessed and are not subject to increase pursuant to rate covenants or municipal or corporate guarantees. The bonds could default if development failed to progress as anticipated or if larger taxpayers failed to pay the assessments, fees and taxes as provided in the financing plans of the districts.

Zero Coupon Bonds. A zero coupon bond is a bond that typically 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, the holder receives the par value of the zero coupon bond, which generates a return equal to 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. This original issue discount (“OID”) approximates the total amount of interest the security will accrue and compound prior to its maturity and reflects the payment deferral and credit risk associated with the instrument. Because zero coupon bonds, and OID instruments generally, allow an issuer to avoid or delay the need to generate cash to meet current interest payments, they may involve greater payment deferral and credit risk than coupon loans and bonds that pay interest currently or in cash. The Fund generally will be required to distribute dividends to shareholders representing the income 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, and use the cash proceeds to make income distributions to its shareholders. For accounting purposes, these cash distributions to shareholders will not be treated as a return of capital.

Special Situations Securities

The Fund may invest in special situations municipal securities. Special situations municipal securities are municipal securities:

●

of issuers that are in default of its obligations or in an active work-out, or are in bankruptcy; or

●

that are otherwise determined by Nuveen Asset Management to be facing distressed financial or operating circumstances.

The portion of the Fund’s assets invested in special situations municipal securities may fluctuate significantly over time according to the availability of attractive special situations municipal securities opportunities. See “Risks—Portfolio Level Risks—Special Situations Municipal Securities Risk” below.

Corporate Debt Securities

The Fund may invest in corporate debt securities, including corporate bonds. Corporate bonds are fully taxable debt obligations issued by corporations. These securities fund capital improvements, expansions, debt refinancing or acquisitions that require more capital than would ordinarily be available from a single lender. Investors in corporate bonds lend money to the issuing corporation in exchange for interest payments and repayment of the principal at a set maturity date. Rates on corporate bonds are set according to prevailing interest rates at the time of the issue, the credit rating of the issuer, the length of the maturity and other terms of the security, such as a call feature.

Corporate bonds come in many varieties and may differ in the way that interest is calculated, the amount and frequency of payments, the type of collateral, if any, and the presence of special features (e.g., conversion rights). The Fund’s investments in corporate bonds may include, but are not limited to, senior, junior, secured and unsecured bonds, notes and other debt securities, and may be fixed rate, variable rate or floating rate, among other things. Holders of corporate bonds, as creditors, have a prior legal claim over common and preferred stockholders as to both income and assets of the issuer for the principal and interest due to them, and may have a prior claim over other creditors, but are generally subordinate to any existing lenders in the issuer’s capital structure.

Corporate bonds are subject to the risk of an issuer’s inability to meet principal and interest payments on the obligations and may also be subject to price volatility due to such factors as market interest rates, the issuer’s performance or credit rating, market perception of the creditworthiness of the issuer and general market liquidity. In addition, corporate restructurings, such as mergers, leveraged buyouts, takeovers or similar corporate transactions are often financed by an increase in a corporate issuer’s debt securities. As a result of the added debt burden, the credit quality and market value of an issuer’s existing corporate bonds may decline significantly. Corporate bonds usually yield more than government or agency bonds due to the presence of credit risk.

U.S. Treasury Securities

The Fund may invest in U.S. Government direct obligations. U.S. Government direct obligation are issued by the United States Treasury and include bills, notes and bonds. Treasury bills are issued with maturities of up to one year. They are issued in bearer form, are sold on a discount basis and are payable at par value at maturity. Treasury notes are longer-term interest-bearing obligations with original maturities of one to seven years. Treasury bonds are longer-term interest-bearing obligations with original maturities from five to thirty years.

Derivatives

The Fund may use certain derivative instruments in pursuit of its investment objectives. Such instruments include financial futures contracts, swap contracts (including interest rate, total return, and credit default swaps), options on financial futures, options on swap contracts or other derivative instruments. The Fund may also use credit default swaps, interest rate swaps and total return swaps. Credit default swaps may require initial premium (discount) payments as well as periodic payments (receipts) related to the interest leg of the swap or to the default of a reference obligation. If the Fund is a seller of a contract, the Fund would be required to pay the par (or other agreed upon) value of a referenced debt obligation to the counterparty in the event of a default or other credit event by the reference issuer, such as a U.S. or foreign corporate issuer, with respect to such debt obligations. In return, the Fund would receive from the counterparty a periodic stream of payments over the term of the contract provided that no event of default has occurred. If no default occurs, the Fund would keep the stream of payments and would have no payment obligations. As the seller, the Fund would be subject to investment exposure on the notional amount of the swap. If the Fund is a buyer of a contract, the Fund would have the right to deliver a referenced debt obligation and receive the par (or other agreed-upon) value of such debt obligation from the counterparty in the event of a default or other credit event (such as a credit downgrade) by the reference issuer, such as a U.S. or foreign corporation, with respect to its debt obligations. In return, the Fund would pay the counterparty a periodic stream of payments over the term of the contract provided that no event of default has occurred. If no default occurs, the counterparty would keep the stream of payments and would have no further obligations to the Fund. Interest rate swaps involve the exchange by the Fund with a counterparty of their respective commitments to pay or receive interest, such as an exchange of fixed-rate payments for floating rate payments. The Fund will usually enter into interest rate swaps on a net basis; that is, the two payment streams will be netted out in a cash settlement on the payment date or dates specified in the instrument, with the Fund receiving or paying, as the case may be, only the net amount of the two payments. In a total return swap, one party agrees to pay the other the "total return" of a defined underlying asset during a specified period, in return for periodic payments based on a fixed or variable interest rate or the total return from other underlying assets. A total return swap may be applied to any underlying asset but is most commonly used with equity indices, single stocks, bonds and defined baskets of loans and mortgages. The Fund might enter into a total return swap involving an underlying index or basket of securities to create exposure to a potentially widely diversified range of securities in a single trade. See “Portfolio Composition and Other Information—Hedging Strategies and Other Uses of Derivatives” in the SAI.

The requirements for qualification as a regulated investment company (“RIC”) may also limit the extent to which the Fund may invest in futures, options on futures and swaps. See “Tax Matters.”

Nuveen Fund Advisors and Nuveen Asset Management may use derivative instruments to seek to enhance return, to hedge some of the risk of the Fund’s investments in municipal securities or as a substitute for a position in the underlying asset. These types of strategies may generate taxable income.

There is no assurance that these derivative strategies will be available at any time or that, if used, that the strategies will be successful.

Swap Transactions. The Fund may enter into total return, interest rate and credit default swap agreements and interest rate caps, floors and collars. The Fund may also enter into options on the foregoing types of swap agreements (“swap options”).

The Fund may enter into swap transactions for any purpose consistent with its investment objectives and strategies, such as for the purpose of attempting to obtain or preserve a particular return or spread at a lower cost than obtaining a return or spread through purchases and/or sales of instruments in other markets, as a duration management technique, to attempt to reduce risk arising from the ownership of a particular instrument, or to gain exposure to certain sectors or markets in the most economical way possible.

Swap agreements are two party contracts entered into primarily by institutional investors for a specified period of time. In a standard swap transaction, two parties agree to exchange the returns (or differentials in rates of return) earned or realized on a particular predetermined asset, reference rate or index. The gross returns to be exchanged or swapped between the parties are generally calculated with respect to a notional amount, e.g., the return on or increase in value of a particular dollar amount invested at a particular interest rate or in a basket of securities representing a particular index. The notional amount of the swap agreement generally is only used as a basis upon which to calculate the obligations that the parties to the swap agreement have agreed to exchange.

Interest Rate Swaps, Caps, Collars and Floors. Interest rate swaps are bilateral contracts in which each party agrees to make periodic payments to the other party based on different referenced interest rates (e.g., a fixed rate and a floating rate) applied to a specified notional amount. The purchase of an interest rate floor entitles the purchaser, to the extent that a specified index falls below a predetermined interest rate, to receive payments of interest on a notional principal amount from the party selling such interest rate floor. The purchase of an interest rate cap entitles the purchaser, to the extent that a specified index rises above a predetermined interest rate, to receive payments of interest on a notional principal amount from the party selling such interest rate cap. Interest rate collars involve selling a cap and purchasing a floor or vice versa to protect the Fund against interest rate movements exceeding given minimum or maximum levels.

The use of interest rate transactions, such as interest rate swaps and caps, is a highly specialized activity that involves investment techniques and risks different from those associated with ordinary portfolio security transactions. Depending on the state of interest rates in general, the Fund’s use of interest rate swaps or caps could enhance or harm the overall performance of the Fund’s common shares. To the extent there is a decline in interest rates, the value of the interest rate swap or cap could decline, and could result in a decline in the NAV of the common shares. In addition, if short-term interest rates are lower than the Fund’s fixed rate of payment on the interest rate swap, the swap will reduce common share net earnings. If, on the other hand, short-term interest rates are higher than the fixed rate of payment on the interest rate swap, the swap will enhance common share net earnings. Buying interest rate caps could enhance the performance of the common shares by providing a maximum leverage expense. Buying interest rate caps could also decrease the net earnings of the common shares in the event that the premium paid by the Fund to the counterparty exceeds the additional amount such Fund would have been required to pay had it not entered into the cap agreement.

Municipal Market Data Rate Locks. The Fund may purchase and sell municipal market data rate locks (“MMD Rate Locks”). An MMD Rate Lock permits the Fund to lock in a specified municipal interest rate for a portion of its portfolio to preserve a return on a particular investment or a portion of its portfolio as a duration management technique or to protect against any increase in the price of securities to be purchased at a later date. By using an MMD Rate Lock, the Fund can create a synthetic long or short position, allowing the Fund to select what the manager believes is an attractive part of the yield curve. The Fund will ordinarily use these transactions as a hedge or for duration or risk management although it is permitted to enter into them to enhance income or gain or to increase the Fund’s yield, for example, during periods of steep interest rate yield curves (i.e., wide differences between short term and long term interest rates). An MMD Rate Lock is a contract between the Fund and an MMD Rate Lock provider pursuant to which the parties agree to make payments to each other on a notional amount, contingent upon whether the Municipal Market Data AAA General Obligation Scale is above or below a specified level on the expiration date of the contract. For example, if the Fund buys an MMD Rate Lock and the Municipal Market Data AAA General Obligation Scale is below the specified level on the expiration date, the counterparty to the contract will make a payment to the Fund equal to the specified level minus the actual level, multiplied by the notional amount of the contract. If the Municipal Market Data AAA General Obligation Scale is above the specified level on the expiration date, the Fund will make a payment to the counterparty equal to the actual level minus the specified level, multiplied by the notional amount of the contract. In connection with investments in MMD Rate Locks, there is a risk that municipal yields will move in the opposite direction than anticipated by the Fund, which would cause the Fund to make payments to its counterparty in the transaction that could adversely affect the Fund’s performance.

Total Return Swaps. In a total return swap, one party agrees to pay the other the “total return” of a defined underlying asset during a specified period, in return for periodic payments based on a fixed or variable interest rate or the total return from other underlying assets. A total return swap may be applied to any underlying asset but is most commonly used with equity indices, single stocks, bonds and defined baskets of loans and mortgages. The Fund might enter into a total return swap involving an underlying index or basket of securities to create exposure to a potentially widely diversified range of securities in a single trade. An index total return swap can be used by the portfolio managers to assume risk, without the complications of buying the component securities from what may not always be the most liquid of markets.

Credit Default Swaps. A credit default swap is a bilateral contract that enables an investor to buy or sell protection against a defined-issuer credit event. The Fund may enter into credit default swap agreements either as a buyer or a seller. The Fund may buy protection to attempt to mitigate the risk of default or credit quality deterioration in an individual security or a segment of the fixed income securities market to which it has exposure, or to take a “short” position in individual bonds or market segments which it does not own. The Fund may sell protection in an attempt to gain exposure to the credit quality characteristics of particular bonds or market segments without investing directly in those bonds or market segments. As the buyer of protection in a credit default swap, the Fund would pay a premium (by means of an upfront payment or a periodic stream of payments over the term of the agreement) in return for the right to deliver a referenced bond or group of bonds to the protection seller and receive the full notional or par value (or other agreed upon value) upon a default (or similar event) by the issuer(s) of the underlying referenced obligation(s). If no default occurs, the protection seller would keep the stream of payments and would have no further obligation to the Fund. Thus, the cost to the Fund would be the premium paid with respect to the agreement. If a credit event occurs, however, the Fund may elect to receive the full notional value of the swap in exchange for an equal face amount of deliverable obligations of the reference entity that may have little or no value. The Fund bears the risk that the protection seller may fail to satisfy its payment obligations.

If the Fund is a seller of protection in a credit default swap and no credit event occurs, the Fund would generally receive an up-front payment or a periodic stream of payments over the term of the swap. If a credit event occurs, however, generally the Fund would have to pay the buyer the full notional value of the swap in exchange for an equal face amount of deliverable obligations of the reference entity that may have little or no value. As the protection seller, the Fund effectively adds the economic effect of leverage to its portfolio because, in addition to being subject to investment exposure on its total net assets, the Fund is subject to investment exposure on the notional amount of the swap. Thus, the Fund bears the same risk as it would by buying the reference obligation(s) directly, plus the additional risks related to obtaining investment exposure through a derivative instrument.

Swap Options. A swap option is a contract that gives a counterparty the right (but not the obligation), in return for payment of a premium, to enter into a new swap agreement or to shorten, extend, cancel, or otherwise modify an existing swap agreement at some designated future time on specified terms. A cash-settled option on a swap gives the purchaser the right, in return for the premium paid, to receive an amount of cash equal to the value of the underlying swap as of the exercise date. The Fund may write (sell) and purchase put and call swap options. Depending on the terms of the particular option agreement, the Fund generally would incur a greater degree of risk when it writes a swap option than when it purchases a swap option. When the Fund purchases a swap option, it risks losing only the amount of the premium it has paid should it decide to let the option expire unexercised. However, when the Fund writes a swap option, upon exercise of the option the Fund would become obligated according to the terms of the underlying agreement.

Futures and Options on Futures. A futures contract is an agreement between two parties to buy and sell a security, index or interest rate (each a “financial instrument”) for a set price on a future date. Certain futures contracts, such as futures contracts relating to individual securities, call for making or taking delivery of the underlying financial instrument. However, these contracts generally are closed out before delivery by entering into an offsetting purchase or sale of a matching futures contract (same exchange, underlying financial instrument, and delivery month). Other futures contracts, such as futures contracts on interest rates and indices, do not call for making or taking delivery of the underlying financial instrument, but rather are agreements pursuant to which two parties agree to take or make delivery of an amount of cash equal to the difference between the value of the financial instrument at the close of the last trading day of the contract and the price at which the contract was originally written. These contracts also may be settled by entering into an offsetting futures contract.

Unlike when the Fund purchases or sells a security, no price is paid or received by the Fund upon the purchase or sale of a futures contract. Initially, the Fund will be required to deposit with the futures broker, known as a futures commission merchant (“FCM”), an amount of cash or securities equal to a varying specified percentage of the contract amount. This amount is known as initial margin. The margin deposit is intended to ensure completion of the contract. Minimum initial margin requirements are established by the futures exchanges and may be revised. In addition, FCMs may establish margin deposit requirements that are higher than the exchange minimums. Cash held in the margin account generally is not income producing. However, coupon bearing securities, such as Treasury securities, held in margin accounts generally will earn income.

Subsequent payments to and from the FCM, called variation margin, will be made on a daily basis as the price of the underlying financial instrument fluctuates, making the futures contract more or less valuable, a process known as marking the contract to market. Changes in variation margin are recorded by the Fund as unrealized gains or losses. At any time prior to expiration of the futures contract, the Fund may elect to close the position by taking an opposite position that will operate to terminate its position in the futures contract. A final determination of variation margin is then made, additional cash is required to be paid by or released to the Fund, and the Fund realizes a gain or loss. In the event of the bankruptcy or insolvency of an FCM that holds margin on behalf of the Fund, the Fund may be entitled to the return of margin owed to it only in proportion to the amount received by the FCM’s other customers, potentially resulting in losses to the Fund. Futures transactions also involve brokerage costs.

A futures option gives the purchaser of such option the right, in return for the premium paid, to assume a long position (call) or short position (put) in a futures contract at a specified exercise price at any time during the period of the option. Upon exercise of a call option, the purchaser acquires a long position in the futures contract and the writer is assigned the opposite short position. Upon the exercise of a put option, the opposite is true.

Bonds

The Fund may invest in a wide variety of bonds of varying maturities issued by the U.S. government and municipalities (during the initial investment period or for temporary defensive measures) and other issuers. Bonds are fixed or variable-rate debt obligations, including bills, notes, debentures, money market instruments and similar instruments and securities. Bonds generally are used by corporations as well as governments and other issuers to borrow money from investors. The issuer pays the investor a fixed or variable rate of interest and normally must repay the amount borrowed on or before maturity. Corporate bonds come in many varieties and may differ in the way that interest is calculated, the amount and frequency of payments, the type of collateral, if any, and the presence of special features (e.g., conversion rights).

Illiquid Investments

The Fund may invest in investments and other instruments that, at the time of investment, are illiquid (i.e., investments that are not readily marketable). For this purpose, illiquid investments may include, but are not limited to, restricted investments (investments the disposition of which is restricted under the federal securities laws), investments that may only be resold pursuant to Rule 144A under the Securities Act of 1933, as amended (the “1933 Act”) that are deemed to be illiquid, and certain repurchase agreements.

Restricted investments may be sold only in privately negotiated transactions or in a public offering with respect to which a registration statement is in effect under the 1933 Act. Where registration is required, the Fund may be obligated to pay all or part of the registration expenses and a considerable period may elapse between the time of the decision to sell and the time the Fund may be permitted to sell an investment under an effective registration statement. If, during such a period, adverse market circumstances were to develop, the Fund might obtain a less favorable price than that which prevailed when it decided to sell. Illiquid investments will be priced at fair value as determined in good faith by the Board of Trustees or its delegate.

Investment Policies

Under normal circumstances the Fund will invest subject to the following policies:

●

The Fund will invest at least 80% of its Assets (as defined below) in municipal securities and other related investments, the income from which is exempt from regular U.S. federal income tax;

●

The Fund will invest at least 75% of its net assets in low- to medium-quality municipal securities that, at the time of investment, are rated BBB/Baa or lower or are unrated but judged by Nuveen Asset Management to be of comparable quality;

●

The Fund may invest up to 25% of its Managed Assets (as defined below) in special situations municipal securities;

●

The Fund will invest no more than 10% of its Managed Assets in any one issuer;

●

The Fund will not invest in common equity securities. This policy does not apply to shares of other investment companies or to common equity securities acquired in connection with a work-out of an issuer of a debt security as discussed below; and

●

The Fund has no limitation as to the maturity or duration of the municipal securities in which it will invest.

The foregoing policies are considered to apply only at the time of investment and will not be considered violated unless an excess or deficiency occurs or exists immediately after and as a result of an acquisition of securities.

Low- to medium-quality municipal securities include below investment grade securities (or “junk bonds”). Below investment grade securities are generally securities rated BB+/Ba1 or lower at the time of investment and are regarded as having predominately speculative characteristics with respect to the issuer’s capacity to pay interest or dividends and repay principal, which implies higher price volatility and default risk than investment grade instruments of comparable terms and duration. For purposes of the investment limitations in this prospectus, a security’s rating is determined using the lowest rating of Moody’s, S&P and Fitch, if rated by at least two of these three NRSROs. If only one of those NRSROs provides a rating, that rating is used. If a security is not rated by any NRSRO, the rating determined by Nuveen Asset Management to be of comparable quality is used. The portion of the Fund’s assets invested in low- to medium-quality municipal securities may vary over time, and may fluctuate significantly over time, over the minimum of 75% described above.

While investments in special situations municipal securities may be a component of the Fund’s investment strategy in pursuit of its investment objectives, the ability of the Fund to invest in special situation municipal securities may be limited by the availability of attractive opportunities in the market. The portion of the Fund’s assets that are invested in such securities, if any, may fluctuate significantly over time up to the 25% limit described above.

Nuveen Asset Management may determine that it is in the best interest of shareholders to pursue a work-out arrangement (i.e., a privately negotiated, mutual agreement between the Fund and the issuer or another party) with respect to a defaulted security, which may involve making loans to the issuer or another party, or purchasing an equity or other interest from the issuer or another party, or other related or similar steps involving the investment of additional monies.

The Fund may enter into certain derivative transactions as a hedging technique to protect against potential adverse changes in the market value of portfolio securities. The Fund also may use derivatives to attempt to protect the NAV of the Fund, to facilitate the sale of certain portfolio securities, to manage the Fund’s effective interest rate exposure, and as a temporary substitute for purchasing or selling particular instruments. From time to time, the Fund also may enter into derivative transactions to create investment exposure to the extent such transactions may facilitate implementation of its strategy more efficiently than through outright purchases or sales of portfolio securities.

For temporary defensive purposes, during periods of high cash inflows or outflows, or during a Repurchase Offer Period, the Fund may depart from its principal investment strategies and invest up to 100% of its Managed Assets in cash equivalents, U.S. government securities and other high-quality short-term debt securities. During such periods, the Fund may not be able to achieve its investment objectives. The Fund may adopt a defensive strategy when Nuveen Asset Management believes the instruments in which the Fund normally invests have elevated risks due to political or economic factors, in the event that unanticipated legal or regulatory developments interfere with implementation of the Fund’s principal investment strategies, and in other extraordinary circumstances.

The Fund’s investment policy to invest at least 80% of its Assets in municipal securities and other related investments, the income from which is exempt from regular U.S. federal income tax and certain other investment restrictions identified in the SAI as such are considered fundamental. See also “Investment Restrictions” in the SAI. The Fund cannot change its fundamental policies without the approval of the holders of a “majority of the outstanding” Common Shares. When used with respect to approval of a changes to the Fund’s fundamental policies, a “majority of the outstanding” shares means (i) 67% or more of the shares present at a meeting, if the holders of more than 50% of the shares are present or represented by proxy or (ii) more than 50% of the shares, whichever is less. All of the Fund’s other investment policies are not considered to be fundamental by the Fund and can be changed by the Board of Trustees without a vote of the Common Shareholders.

Risk Factors [Table Text Block]

Risks

The Fund is a diversified, closed-end management investment company that continuously offers its Common Shares and is operated as an interval fund. The Fund is not intended to be a complete investment program and, due to the uncertainty inherent in all investments, there can be no assurance that the Fund will achieve its investment objectives. The Fund’s performance and the value of its investments will vary in response to changes in interest rates, inflation, the financial condition of a security’s issuer, ratings on a security, perceptions of the issuer, and other market factors. Your Common Shares at any point in time may be worth less than your original investment, even after taking into account the reinvestment of Fund dividends and distributions.

Portfolio Level Risks

Alternative Minimum Tax Risk—The Fund may invest in AMT Bonds. Therefore, a portion of the Fund’s otherwise exempt-interest dividends may be taxable to those shareholders subject to the federal alternative minimum tax.

Below Investment Grade Risk—Investments of below investment grade quality are regarded as having speculative characteristics with respect to the issuer’s capacity to pay dividends or interest and repay principal, and may be subject to higher price volatility and default risk than investment grade investments of comparable terms and duration. Issuers of lower grade investments may be highly leveraged and may not have available to them more traditional methods of financing. The prices of these lower grade investments 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 investments may not be as liquid as the secondary market for more highly rated investments, a factor which may have an adverse effect on the Fund’s ability to dispose of a particular investment.

If a below investment grade security goes into default, or its issuer enters bankruptcy, it might be difficult to sell that security in a timely manner at a reasonable price.

Call Risk—The Fund may invest in municipal securities that are subject to call risk. Such municipal securities may be redeemed at the option of the issuer, or “called,” before their stated maturity or redemption date. In general, an issuer will call its instruments if they can be refinanced by issuing new instruments that bear a lower interest rate. The Fund is subject to the possibility that during periods of falling interest rates, an issuer will call its high yielding municipal securities. The Fund would then be forced to invest the unanticipated proceeds at lower interest rates, resulting in a decline in the Fund’s income.

Credit Spread Risk—Credit spread risk is the risk that credit spreads (i.e., the difference in yield between investments that is due to differences in their credit quality) may increase when the market believes that municipal securities generally have a greater risk of default. Increasing credit spreads may reduce the market values of the Fund’s investments. Credit spreads often increase more for lower rated and unrated investments than for investment grade investments. In addition, when credit spreads increase, reductions in market value will generally be greater for longer-maturity investments.

Debt Securities Risk— Issuers of debt instruments in which the Fund may invest may default on their obligations to pay principal or interest when due. This non-payment would result in a reduction of income to the Fund, a reduction in the value of a debt instrument experiencing non-payment and, potentially, a decrease in the NAV of the Fund. There can be no assurance that liquidation of collateral would satisfy the issuer’s obligation in the event of non-payment of scheduled interest or principal or that such collateral could be readily liquidated. In the event of bankruptcy of an issuer, the Fund could experience delays or limitations with respect to its ability to realize the benefits of any collateral securing a security. To the extent that the credit rating assigned to a security in the Fund’s portfolio is downgraded, the market price and liquidity of such security may be adversely affected. In addition, decreased market making capacity has the potential to decrease liquidity and increase price volatility in the fixed income markets in which the Fund invests, particularly during periods of economic or market stress. Decreased liquidity may result in the Fund having to accept a lower price to sell a security, sell other securities to raise cash, or give up an investment opportunity, any of which could have a negative effect on performance.

Defaulted and Distressed Investments Risk—The Fund may invest in investments of an issuer that is in default or that is in bankruptcy or insolvency proceedings at the time of purchase. In addition, the Fund may hold investments that at the time of purchase are not in default or involved in bankruptcy or insolvency proceedings, but may later become so. Moreover, the Fund may invest in investments either rated CCC or lower, or unrated but judged by the portfolio managers to be of comparable quality. Some or many of these low-rated investments, although not in default, may be “distressed,” meaning that the issuer is experiencing financial difficulties or distress at the time of acquisition. Such investments would present a substantial risk of future default which may cause the Fund to incur losses, including additional expenses, to the extent it is required to seek recovery upon a default in the payment of principal or interest on those investments. In any reorganization or liquidation proceeding relating to a portfolio investment, the Fund may lose its entire investment or may be required to accept cash or investments with a value less than its original investment. Defaulted or distressed investments may be subject to restrictions on resale.

Derivatives Risk—The Fund’s use of derivatives involves risks different from, and possibly greater than, the risks associated with investing directly in the investments underlying the derivatives. If the Fund enters into a derivative transaction, it could lose more than the principal amount invested. The risks associated with derivatives transactions include (i) the imperfect correlation between the value of such instruments and the underlying assets, (ii) the possible default of the counterparty to the transaction, (iii) illiquidity of the derivative instruments, and (iv) high volatility losses caused by unanticipated market movements, which are potentially unlimited. Although both over-the-counter (“OTC”) and exchange-traded derivatives markets may experience a lack of liquidity, OTC non-standardized derivative transactions are generally less liquid than exchange-traded instruments. The illiquidity of the derivatives markets may be due to various factors, including congestion, disorderly markets, limitations on deliverable supplies, the participation of speculators, government regulation and intervention, and technical and operational or system failures. In addition, daily limits on price fluctuations and speculative position limits on exchanges on which the Fund may conduct its transactions in derivative instruments may prevent prompt liquidation of positions, subjecting the Fund to the potential of greater losses.

Whether the Fund’s use of derivatives is successful will depend on, among other things, Nuveen Fund Advisors and Nuveen Asset Management correctly forecasting market circumstances, liquidity, market values, interest rates and other applicable factors. If Nuveen Fund Advisors and Nuveen Asset Management incorrectly forecast these and other factors, the investment performance of the Fund will be unfavorably affected. In addition, there can be no assurance that the derivatives investing techniques, as they may be developed and implemented by the Fund, will be successful in mitigating risk or achieving the Fund’s investment objectives. The use of derivatives to enhance returns may be particularly speculative.

The use of derivatives is a highly specialized activity that involves investment techniques and risks different from those associated with ordinary portfolio securities transactions. In addition, the use of derivatives requires an understanding by the portfolio managers of not only the referenced asset, rate or index, but also of the derivative itself.

The use of certain derivatives involves leverage, which can cause the Fund’s portfolio to be more volatile than if the portfolio had not been leveraged. Leverage can significantly magnify the effect of price movements of the reference asset, disproportionately increasing the Fund’s losses and reducing the Fund’s opportunities for gains when the reference asset changes in unexpected ways. In some instances, such leverage could result in losses that exceed the original amount invested. It is possible that regulatory or other developments in the derivatives market, including changes in government regulation, could adversely impact the Fund’s ability to invest in certain derivatives or successfully use derivative instruments.

Duration Risk—Duration is the sensitivity, expressed in years, of the price of a fixed-income security to changes in the general level of interest rates (or yields). Securities with longer durations tend to be more sensitive to interest rate (or yield) changes, which typically corresponds to increased volatility and risk, than securities with shorter durations. For example, if a security or portfolio has a duration of three years and interest rates increase by 1%, then the security or portfolio would decline in value by approximately 3%. Duration differs from maturity in that it considers potential changes to interest rates, and a security’s coupon payments, yield, price and par value and call features, in addition to the amount of time until the security matures. The duration of a security will be expected to change over time with changes in market factors and time to maturity.

Fair Value Risk—The Fund’s investments may include certain assets that are not publicly traded and for which no market-based price quotation is available. As a result, the value of those investments will be determined in good faith by the Fund’s fair valuation designee. However, because it may be difficult to obtain financial and other information with respect to such investments, and because any available information might be incomplete or inaccurate, such valuations are inherently uncertain and may be based on estimates. Accordingly, determinations of fair value for such investments may differ materially from the values that would be assessed if a readily available market for such investments existed. In addition, such fair value may not reflect the price at which the Fund could dispose of its interests in a particular portfolio Investment at any given time. Due to this uncertainty, fair value determinations with respect to any non-publicly traded investments held by the Fund may cause the Fund’s NAV on a given day to be materially understated or overstated. In addition, the valuation of these types of investments may result in substantial write-downs and earnings volatility, which may negatively impact the Fund’s NAV. As a result, investors purchasing Common Shares based on an overstated NAV may pay a higher price than the value of the Fund’s portfolio holdings might warrant. Conversely, investors tendering Common Shares for repurchase based on an understated NAV may receive a lower price than the value the Fund’s portfolio holdings might warrant. In addition, the participation of any portfolio managers in the Fund’s valuation process could result in a conflict of interest as the management fee (including any particular sub-advisory fee) is based on the amount of assets within the Fund (or allocated to Nuveen Asset Management). The Fund’s NAV could be adversely affected if determinations regarding the fair value of these investments were materially higher than the values ultimately realized upon the disposal of such investments.

Hedging Risk—The Fund’s use of derivatives or other transactions to reduce risk involves costs and will be subject to Nuveen Asset Management’s ability to predict correctly changes in the relationships of such hedge instruments to the Fund’s portfolio holdings or other factors. No assurance can be given that Nuveen Asset Management’s judgment in this respect will be correct, and no assurance can be given that the Fund will enter into hedging or other transactions at times or under circumstances in which it may be advisable to do so. Hedging activities may reduce the Fund’s opportunities for gain by offsetting the positive effects of favorable price movements and may result in net losses.

Inflation 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. Currently, inflation rates are elevated relative to normal market conditions and could increase.

Insurance Risk—The Fund may purchase municipal securities that are secured by insurance, bank credit agreements or escrow accounts. The credit quality of the companies that provide such credit enhancements will affect the value of those securities. Certain significant providers of insurance for municipal securities have incurred significant losses as a result of exposure to sub-prime mortgages and other lower credit quality investments. As a result, such losses have reduced the insurers’ capital and called into question their continued ability to perform their obligations under such insurance if they are called upon to do so in the future. While an insured municipal security will typically be deemed to have the rating of its insurer, if the insurer of a municipal security suffers a downgrade in its credit rating or the market discounts the value of the insurance provided by the insurer, the value of the municipal security would more closely, if not entirely, reflect such rating. In such a case, the value of insurance associated with a municipal security may not add any value. The insurance feature of a municipal security 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 Common Shares represented by such insured obligation.

Interest Rate Risk— Generally, when market interest rates rise, the market value of such securities will fall, and vice versa. Interest rate risk is the risk that municipal securities in the Fund’s portfolio will decline in value because of changes 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. If the Fund invests in floating rate securities, the market value of such securities may fall in a declining interest rate environment and may also fall in a rising interest rate environment if there is a lag between the rise in interest rates and the rest. A secondary risk associated with declining interest rates is the risk that income earned by the Fund on floating rate securities may decline due to lower coupon payments on floating-rate securities.

Inverse Floating Rate Securities Risk—Typically, inverse floating rate securities represent beneficial interests in a special purpose trust(sometimes called a “tender option bond trust”) formed for the purpose of holding municipal bonds. See “Portfolio Composition and Other Information—Municipal Securities—Inverse Floating Rate Securities” in the SAI. In general, income on inverse floating rate securities will decrease when short-term interest rates increase and increase when short-term interest rates decrease. Investments in inverse floating rate securities may subject the Fund to the risks of reduced or eliminated interest payments and losses of principal.

The Fund may invest in inverse floating rate securities issued by special purpose trusts that have recourse to the Fund (i.e., the Fund typically bears the risk of loss with respect to any liquidity shortfall). In Nuveen Fund Advisors’ and Nuveen Asset Management’s discretion, the Fund may enter into a separate shortfall and forbearance agreement with the third party granting liquidity to the floating rate security holders of the special purpose trust. Such an agreement would require the Fund to reimburse the third party granting liquidity to the floating rate security holders of the special purpose trust, upon termination of the trust issuing the inverse floater, the difference between the liquidation value of the bonds held in the trust and the principal amount due to the holders of floating rate interests. In such instances, the Fund may be at risk of loss that exceeds its investment in the inverse floating rate securities. The Fund may enter into such recourse agreements (i) when the liquidity provider to the special purpose trust requires such an agreement because the level of leverage in the trust exceeds the level that the liquidity provider is willing to support absent such an agreement; and/or (ii) to seek to prevent the liquidity provider from collapsing the trust in the event that the municipal obligation held in the trust has declined in value. Inverse floating rate securities may increase or decrease in value at a greater rate than the underlying interest rate, which effectively leverages the Fund’s investment. As a result, the market value of such securities generally will be more volatile than that of fixed rate securities.

The Fund’s investments in inverse floating rate securities issued by special purpose trusts that have recourse to the Fund may be highly leveraged. The structure and degree to which the Fund’s inverse floating rate securities are highly leveraged will vary based upon a number of factors, including the size of the trust itself and the terms of the underlying municipal security. In the event of a significant decline in the value of an underlying security, the Fund may suffer losses in excess of the amount of its investment (up to an amount equal to the value of the municipal securities underlying the inverse floating rate securities) as a result of liquidating special purpose trusts or other collateral required to maintain the Fund’s anticipated leverage ratio.

The Fund’s investment in inverse floating rate securities has the economic effect of leverage. Any leverage achieved through the Fund’s investment in inverse floating rate securities will create an opportunity for increased Common Share net income and returns, but will also create the possibility that Common Share long-term returns will be diminished if the cost of leverage exceeds the return on the inverse floating rate securities purchased by the Fund. See “Risks—Fund Level Risks—Leverage Risk.”

The amount of fees paid to Nuveen Asset Management for investment advisory services will be higher if the Fund uses leverage because the fees will be calculated based on the Fund’s Managed Assets—this may create an incentive for Nuveen Asset Management to leverage the Fund. “Managed Assets” means the total assets of the Fund, minus the sum of its accrued liabilities (other than liabilities incurred for the express purpose of creating leverage). Total assets for this purpose shall include assets attributable to the Fund’s use of leverage (whether or not those assets are reflected in the Fund’s financial statements for purposes of generally accepted accounting principles), and derivatives will be valued at their market value.

Inverse floating rate securities have varying degrees of liquidity based, among other things, upon the liquidity of the underlying securities deposited in a special purpose trust. The market price of inverse floating rate securities is more volatile than the underlying securities due to leverage. The leverage attributable to such inverse floating rate securities may be “called away” on relatively short notice and therefore may be less permanent than more traditional forms of leverage. In certain circumstances, the likelihood of an increase in the volatility of NAV and market price of the Common Shares may be greater for a fund (like the Fund) that relies primarily on inverse floating rate securities to achieve a desired leverage ratio. The Fund may be required to sell its inverse floating rate securities at less than favorable prices, or liquidate other Fund portfolio holdings in certain circumstances, including, but not limited to, the following:

●

If the Fund has a need for cash and the securities in a special purpose trust are not actively traded due to adverse market conditions;

●

If special purpose trust sponsors (as a collective group or individually) experience financial hardship and consequently seek to terminate their respective outstanding special purpose trusts; and

●

If the value of an underlying security declines significantly and if additional collateral has not been posted by the Fund.

There is no assurance that the Fund’s strategy of investing in inverse floating rate securities will be successful.

Issuer Credit Risk—Issuers of securities in which the Fund may invest may default, or may be in default at the time of purchase, on their obligations to pay dividends, principal or interest when due. This non-payment would result in a reduction of income to the Fund, a reduction in the value of a security experiencing non-payment and, potentially, a decrease in the NAV of the Fund. With respect to the Fund’s investments insecurities that are secured, there can be no assurance that liquidation of collateral would satisfy the issuer’s obligation in the event of non-payment of a scheduled dividend, interest or principal payment or that such collateral could be readily liquidated. In the event of the bankruptcy of an issuer, the Fund could experience delays or limitations with respect to its ability to realize the benefits of any collateral securing a security. To the extent that the credit rating assigned to a security in the Fund’s portfolio is downgraded, the market price and liquidity of such security may be adversely affected.

Municipal Securities Market Risk—Investing in the municipal securities market involves certain risks. The municipal market is one in which dealer firms make markets in bonds on a principal basis using their proprietary capital, and during the market turmoil in 2008-2009 these firms’ capital was severely constrained. As a result, some firms were unwilling to commit their capital to purchase and to serve as a dealer for municipal bonds. The amount of public information available about the municipal securities in the Fund’s portfolio is generally less than that for corporate equities or bonds, and the investment performance of the Fund may therefore be more dependent on the analytical abilities of Nuveen Asset Management than if the Fund were a stock fund or taxable bond fund. In addition, the market for below investment grade municipal securities has experienced in the past, and may experience in the future, periods of significant volatility, which could negatively impact the value of the municipal securities in the Fund’s portfolio.

The ability of municipal issuers to make timely payments of interest and principal may be diminished during general economic downturns and as governmental cost burdens are reallocated among federal, state and local governments. In addition, laws enacted in the future by Congress or state legislatures or referenda could extend the time for payment of principal and/or interest, or impose other constraints on enforcement of such obligations, or on the ability of municipalities to levy taxes. Further, some state and local governments have been and in the future may be subject to direct ballot referenda that could limit their financial flexibility, or their ability to levy taxes or raise revenues, which may adversely affect the marketability of notes and bonds issued by those state and local governments. Issuers of municipal securities might seek protection under the bankruptcy laws. In the event of bankruptcy of such an issuer, the Fund could experience delays in collecting principal and interest and the Fund may not, in all circumstances, be able to collect all principal and interest to which it is entitled. To enforce its rights in the event of a default in the payment of interest or repayment of principal, or both, the Fund may take possession of and manage the assets securing the issuer’s obligations on such securities, which may increase the Fund’s operating expenses. Any income derived from the Fund’s ownership or operation of such assets may not be tax-exempt.

Municipal Securities Market Liquidity Risk—Inventories of municipal securities held by brokers and dealers have decreased in recent years, lessening their ability to make a market in these securities. This reduction in market making capacity has the potential to decrease the Fund’s ability to buy or sell municipal securities at attractive prices, and increase municipal security price volatility and trading costs, particularly during periods of economic or market stress. The secondary market for municipal securities, particularly the below investment grade municipal securities in which the Fund may invest, also tends to be less well-developed or liquid than many other securities markets, which may adversely affect the Fund’s ability to sell its municipal securities at attractive prices. In addition, recent federal banking regulations may cause certain dealers to reduce their inventories of municipal securities, which may further decrease the Fund’s ability to buy or sell municipal securities. As a result, the Fund may be forced to accept a lower price to sell a security, to sell other securities to raise cash, or to give up an investment opportunity, any of which could have a negative effect on performance. If the Fund needed to sell large blocks of municipal securities to raise cash to meet its obligations, those sales could further reduce the municipal securities’ prices and hurt performance. The Fund may invest a significant portion of its assets in unrated municipal securities. The market for these municipal securities may be less liquid than the market for rated municipal securities of comparable quality. Less public information is typically available about unrated municipal securities or issuers than rated municipal securities or issuers.

Puerto Rico Municipal Securities Market Risk—To the extent that the Fund invests a significant portion of its assets in the securities issued by the Commonwealth of Puerto Rico or its political subdivisions, agencies, instrumentalities, or public corporations (collectively referred to in this prospectus as “Puerto Rico” or the “Commonwealth”), it will be disproportionally affected by political, social and economic conditions and developments in the Commonwealth. In addition, economic, political or regulatory changes in that territory could adversely affect the value of the Fund’s investment portfolio.

Puerto Rico currently is experiencing significant fiscal and economic challenges, including substantial debt service obligations, high levels of unemployment, underfunded public retirement systems, and persistent government budget deficits. These challenges may negatively affect the value of the Fund’s investments in Puerto Rican municipal securities. Several major ratings agencies have downgraded the general obligation debt of Puerto Rico to below investment grade and continue to maintain a negative outlook for this debt, which increases the likelihood that the rating will be lowered further. In both August 2015 and January 2016, Puerto Rico defaulted on its debt by failing to make full payment due on its outstanding bonds, and there can be no assurance that Puerto Rico will be able to satisfy its future debt obligations. 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 Rican municipal securities. Additionally, numerous issuers have entered Title III of the Puerto Rico Oversite, Management and Economic Stability Act (“PROMESA”), which is similar to bankruptcy protection, through which the Commonwealth of Puerto Rico can restructure its debt. While most of Puerto Rico’s debt has been restructured, proceedings under PROMESA remain ongoing, and it is unclear at this time how those proceedings will be resolved or what impact they will have on the value of the Fund’s investments in Puerto Rico municipal securities. There can also be no assurances that these debt restructuring efforts will be effective or that Puerto Rico will be able to service debt payments following the completion of such debt restructuring. In addition, any restructurings approved by a federal court could be appealed and overturned. The mediation process and certain litigation is ongoing with respect to certain municipal securities issued by Puerto Rico and its political subdivisions, instrumentalities and authorities. It is not presently possible to predict the results of this mediation and litigation, but such outcomes will have a significant impact on bondholders of those municipal securities. Further legislation by the U.S. Congress, or actions by the oversight board established by PROMESA, or court approval of an unfavorable debt restructuring deal could have a negative impact on the marketability, liquidity or value of certain investments held by the Fund and could reduce the Fund’s performance.

These challenges and uncertainties have been exacerbated by Hurricanes Irma and Maria and the resulting natural disaster in Puerto Rico since2017. In September 2017, Hurricanes Irma and Maria struck Puerto Rico, causing major damage across the Commonwealth, including damage to its water, power, and telecommunications infrastructure. The length of time needed to rebuild Puerto Rico’s infrastructure is unclear, but could amount to years, during which the commonwealth is likely to be in an uncertain economic state. The full extent of the natural disaster’s impact on Puerto Rico’s economy and foreign investment in Puerto Rico is difficult to estimate.

In addition, in late December 2019 and January 2020, a series of earthquakes hit Puerto Rico, including a magnitude 6.4 earthquake, the most powerful earthquake to hit the island in more than a century, causing an estimated $200 million in damage. In early 2020, as the population of Puerto Rico worked to recover from these natural disasters, the island was adversely impacted by the health related and economic effects of theCOVID-19 pandemic, resulting in the Commonwealth's authorization of a $787 million relief package to fight the pandemic and its economic impacts. Any reduction in the Commonwealth’s, revenues could have a negative ability on the Commonwealth to meet its debt service obligations, including with respect to debt held by the Fund. Puerto Rico’s political and economic conditions could have a negative impact on the liquidity or value of Puerto Rican municipal securities, and consequently may affect the Fund’s investments and its performance if the Fund invests a significant portion of its assets in Puerto Rican municipal securities.

Reinvestment Risk—Reinvestment risk is the risk that income from the Fund’s portfolio will decline if and when the Fund invests the proceeds from matured, traded or called municipal securities at market interest rates that are below the portfolio’s current earnings rate. A decline in income could affect the Common Shares’ NAV and/or a Common Shareholder’s overall returns. As the average maturity of the Fund’s portfolio shortens, the Fund will reinvest in shorter maturity securities at market interest rates that may be lower than at the Fund’s inception.

Restricted and Illiquid Investments Risk—Illiquid investments are investments that are not readily marketable. These investments may include restricted investments, including Rule 144A securities, which cannot be resold to the public without an effective registration statement under the Securities Act of 1933, as amended (the “1933 Act”), or, if they are unregistered, may be sold only in a privately negotiated transaction or pursuant to an exemption from registration. The Fund may not be able to readily dispose of such investments at prices that approximate those at which the Fund could sell such investments if they were more widely traded and, as a result of such illiquidity, the Fund may have to sell other investments or engage in borrowing transactions if necessary to raise cash to meet its obligations. Limited liquidity can also affect the market price of investments, thereby adversely affecting the Fund’s NAV and ability to make dividend distributions. The financial markets in general have in recent years experienced periods of extreme secondary market supply and demand imbalance, resulting in a loss of liquidity during which market prices were suddenly and substantially below traditional measures of intrinsic value. During such periods, some investments could be sold only at arbitrary prices and with substantial losses. Periods of such market dislocation may occur again at any time.

Reverse Repurchase Agreement Risk—Reverse repurchase agreements involve the sale of securities held by the Fund with an agreement to repurchase the securities at an agreed-upon price and date, thereby establishing an effective interest rate. The Fund’s use of reverse repurchase agreements, in economic essence, constitute a securitized borrowing by the Fund from the security purchaser. The Fund may enter into reverse repurchase agreements for the purpose of creating a leveraged investment exposure and, as such, their usage involves essentially the same risks associated with a leveraging strategy generally since the proceeds from these agreements may be invested in additional portfolio securities. Reverse repurchase agreements tend to be short-term in tenor, and there can be no assurances that the purchaser (lender) will commit to extend or “roll” a given agreement upon its agreed-upon repurchase date or an alternative purchaser can be identified on similar terms.

Reverse repurchase agreements also involve the risk that the purchaser fails to return the securities as agreed upon, files for bankruptcy or becomes insolvent. The Fund may be restricted from taking normal portfolio actions during such time, could be subject to loss to the extent that the proceeds of the agreement are less than the value of securities subject to the agreement and may experience adverse tax consequences.

Special Risks Related to Certain Municipal Obligations—Municipal leases and certificates of participation involve special risks not normally associated with general obligations or revenue bonds. Leases and installment purchase or conditional sale contracts (which normally provide for title to the leased asset to pass eventually to the governmental issuer) have evolved as a means for governmental issuers to acquire property and equipment without meeting the constitutional and statutory requirements for the issuance of debt. The debt issuance limitations are deemed to be inapplicable because of the inclusion in many leases or contracts of “non-appropriation” clauses that relieve the governmental issuer of any obligation to make future payments under the lease or contract unless money is appropriated for such purpose by the appropriate legislative body. In addition, such leases or contracts may be subject to the temporary abatement of payments in the event that the governmental issuer is prevented from maintaining occupancy of the leased premises or utilizing the leased equipment. Although the obligations may be secured by the leased equipment or facilities, the disposition of the property in the event of non-appropriation or foreclosure might prove difficult, time consuming and costly, and may result in a delay in recovering or the failure to fully recover the Fund’s original investment. In the event of non-appropriation, the issuer would be in default and taking ownership of the assets may be a remedy available to the Fund, although the Fund does not anticipate that such a remedy would normally be pursued.

Certificates of participation involve the same risks as the underlying municipal leases. In addition, the Fund may be dependent upon the municipal authority issuing the certificates of participation to exercise remedies with respect to the underlying securities. Certificates of participation also entail a risk of default or bankruptcy, both of the issuer of the municipal lease and also the municipal agency issuing the certificate of participation.

Special Situations Municipal Securities Risk—The availability of special situations municipal securities that present attractive investment opportunities has historically been sporadic and may in the future be rare or at times non-existent. As such, the portion of the Fund’s assets invested in special situations municipal securities may fluctuate significantly over time according to the availability of attractive special situations municipal securities opportunities. At times when the portion of the Fund’s assets invested in special situations municipal securities is low, due to lack of availability of special situations municipal securities or otherwise, that low level exposure to such securities may impede the Fund’s ability to fully pursue its investment objectives.

Special situations municipal securities present both unusual opportunities and challenges. The ability of the Fund to capitalize on its investments in special situations municipal securities will be dependent on several factors including, but not limited to, Nuveen Asset Management’s ability (1)to select special situations municipal securities to invest in that have good prospects for improving their creditworthiness over time, or otherwise experiencing price improvement; (2) to manage the various special situations municipal securities’ credits through the recovery process, including work-outs, buyouts and bankruptcies; (3) to buy attractively-priced special situations municipal securities that have the potential to appreciate significantly in value or minimize losses, depending on market conditions; and (4) to liquidate its investments in special situations municipal securities, either by selling such securities to other investors at attractive prices, or by receiving cash, securities or other assets of value after and as a result of a work-out or the issuer’s emergence from bankruptcy.

Nuveen Asset Management’s ability to succeed in these efforts will require skills and techniques that are different from or in addition to the skills and techniques used by a typical municipal investment manager. There is no assurance that Nuveen Asset Management will succeed in its efforts, or that market circumstances will end up being favorable to deriving outsized returns from investments in special situations municipal securities.

Tax Risk—The value of the Fund’s investments and its NAV may be adversely affected by changes in tax rates, rules and policies. Additionally, the Fund is not a suitable investment for individual retirement accounts, for other tax-exempt or tax-deferred accounts or for investors who are not sensitive to the federal income tax consequences of their investments. The Fund’s investment in AMT Bonds may trigger adverse tax consequences for Fund shareholders who are subject to the federal alternative minimum tax. If you are, or as a result of investment in the Fund would become, subject to the federal alternative minimum tax, the Fund may not be a suitable investment for you. In addition, distributions of taxable ordinary income (including any net short-term capital gain) will be taxable to shareholders as ordinary income (and not eligible for favorable taxation as “qualified dividend income”), and capital gain dividends will be taxable as long-term capital gains. Interest income on municipal securities also may be subject to state and local income taxes. See “Tax Matters.”

Taxability Risk—The Fund will invest in municipal securities in reliance at the time of purchase on an opinion of bond counsel to the issuer that the interest paid on those securities will be excludable from gross income for federal income tax purposes, and Nuveen Asset Management will not independently verify that opinion. Subsequent to the Fund’s acquisition of such a municipal security, however, the security may be determined to pay, or to have paid, taxable income. As a result, the treatment of dividends previously paid or to be paid by the Fund as “exempt-interest dividends” could be adversely affected, subjecting the Fund’s shareholders to increased federal income tax liabilities.

Certain other investments made by the Fund, including derivatives transactions, may result in the receipt of taxable income or gains by the Fund. Distributions of taxable ordinary income (including any net short-term capital gain) will be taxable to shareholders as ordinary income (and not eligible for favorable taxation as “qualified dividend income”), and capital gain dividends will be taxable as long-term capital gains. See “Tax Matters.”

Tender Option Bond Regulatory Risk—The federal banking regulators, the SEC and the CFTC in recent years have adopted rules and regulations that have impacted or may impact TOB trusts and securities issued by such trusts, including most notably the so-called “Volcker Rule”, added to the Bank Holding Company Act of 1956 with the adoption of the Dodd-Frank Act. The Volcker Rule places certain restrictions on the ability of any “banking entity” to sponsor, acquire interests in and engage in certain activities with a TOB trust. As a result, certain activities to support the remarketing of floating rate certificates undertaken by banking entities, in their role as remarketing agents or liquidity providers to TOB trusts, before the compliance date for the Volcker Rule, are no longer permitted under the standard TOB trust structure. To be compliant with the Volcker Rule, the standard TOB trust structure has been modified since the Rule’s adoption (i) to shift certain rights and responsibilities from the remarketing agent and liquidity provider to the owners of the inverse floating rate securities such as the Fund itself, and (ii) to change the way in which liquidity is provided to support remarketing of the floating rate securities. Holders of the inverse floating rate securities, including the Fund, may delegate many of these responsibilities to a third party administrator, which would generate additional costs relative to the standard TOB trust structure. The total impact of these modifications remains to be fully seen, but the operational and structural changes associated with these modifications may make early unwinds of TOB trusts in adverse market scenarios more likely, may make the use of TOB trusts more expensive and, overall, may make it more difficult to use TOB trusts to effectively leverage municipal investments to the extent that the Fund may desire. In addition, these modifications have raised or may raise other regulatory issues that may require further refinement to the structure, may impede the future use of TOB trusts as a means of financing leverage, or may increase future costs of TOB-based leverage.

Tobacco Settlement Bond Risk—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 in the Master Settlement Agreement, an agreement between 46 states and nearly all of the U.S. tobacco manufacturers (the “MSA”). Under the terms of the MSA, the actual amount of future settlement payments by tobacco manufacturers is dependent on many factors, including, among other things, reduced cigarette consumption. Payments made by tobacco manufacturers could be negatively impacted if the decrease in tobacco consumption is significantly greater than the forecasted decline.

Unrated Investments Risk—Unrated investments determined by Nuveen Asset Management to be of comparable quality to rated investments which the Fund may purchase may pay a higher dividend or interest rate than such rated investments and be subject to a greater risk of illiquidity or price changes. Less public information is typically available about unrated investments or issuers than rated investments or issuers.

Some unrated investments may not have an active trading market or may be difficult to value, which means the Fund might have difficulty selling them promptly at an acceptable price. To the extent that the Fund invests in unrated investments, the Fund’s ability to achieve its investment objective will be more dependent on Nuveen Asset Management’s credit analysis than would be the case when the Fund invests in rated securities.

Valuation Risk—Certain securities in which the Fund invests typically are valued by a pricing service utilizing a range of market-based inputs and assumptions, including readily available market quotations obtained from broker-dealers making markets in such instruments, cash flows and transactions for comparable instruments. In addition, a portion of the Fund’s investments may be in investments that do not have readily ascertainable market prices. Investments that are not publicly traded or whose market prices are not readily available are valued at fair value as determined in good faith by the Fund’s fair value designee. There is no assurance that the Fund will be able to sell a portfolio security at the price established by the pricing service, which could result in a loss to the Fund. Pricing services generally price securities assuming orderly transactions of an institutional “round lot” size, but some trades may occur in smaller, “odd lot” sizes, often at lower prices than institutional round lot trades. Different pricing services may incorporate different assumptions and inputs into their valuation methodologies, potentially resulting in different values for the same securities. As a result, if the Fund were to change pricing services, or if the Fund’s pricing service were to change its valuation methodology, there could be a material impact, either positive or negative, on the Fund’s NAV.

When- Issued and Delayed Delivery Transactions Risk—When-issued and delayed-delivery transactions may involve an element of risk because no interest accrues on the securities prior to settlement and, because securities are subject to market fluctuations, the value of the securities at time of delivery may be less (or more) than their cost. A separate account of the Fund will be established with its custodian consisting of cash equivalents or liquid securities having a market value at all times at least equal to the amount of any delayed payment commitment.

Zero Coupon Bonds Risk or Pay-In-Kind Securities Risk—Zero Coupon and pay-in-kind securities may be subject to greater fluctuation in value and less liquidity in the event of adverse market conditions than comparably rated securities paying cash interest at regular interest payment periods. Prices on non-cash-paying instruments may be more sensitive to changes in the issuer’s financial condition, fluctuation in interest rates and market demand/supply imbalances than cash-paying securities with similar credit ratings, and thus may be more speculative.

Fund Level Risks

Active Management Risk—The portfolio managers actively manage the Fund’s investments. Consequently, the Fund is subject to the risk that the investment techniques and risk analyses employed by the portfolio managers may not produce the desired results. This could cause the Fund to lose value or its investment results to lag behind relevant benchmarks or other funds with similar objectives.

Borrowing Risk—In addition to borrowing for leverage, the Fund may borrow for temporary or emergency purposes, to pay dividends, repurchase its shares, or clear portfolio transactions. Borrowing may exaggerate changes in the NAV of the Fund’s shares and may affect the Fund’s net income. When the Fund borrows money, it must pay interest and other fees, which will reduce the Fund’s returns if such costs exceed the returns on the portfolio securities purchased or retained with such borrowings. Any such borrowings are intended to be temporary. However, under certain market circumstances, such borrowings might be outstanding for longer periods of time.

Fund Tax Risk—The Fund has elected to be treated and intends to qualify each year as a Regulated Investment Company (“RIC”) under the Internal Revenue Code of 1986, as amended (the “Code”). As a RIC, the Fund is not expected to be subject to U.S. federal income tax to the extent that it distributes its investment company taxable income and net capital gains. To qualify for the special tax treatment available to a RIC, the Fund must comply with certain investment, distribution, and diversification requirements. Under certain circumstances, the Fund may be forced to sell certain assets when it is not advantageous in order to meet these requirements, which may reduce the Fund’s overall return. If the Fund fails to meet any of these requirements, subject to the opportunity to cure such failures under applicable provisions of the Code, the Fund’s income would be subject to a double level of U.S. federal income tax. The Fund’s income, including its net capital gain, would first be subject to U.S. federal income tax at regular corporate rates, even if such income were distributed to shareholders and, second, all distributions by the Fund from earnings and profits, including distributions of net capital gain (if any), would be taxable to shareholders as dividends.

Investment and Market Risk—An investment in Common Shares is subject to investment risk, including the possible loss of the entire principal amount that you invest. Your investment in Common Shares represents an indirect investment in the securities owned by the Fund. Your Common Shares at any point in time may be worth less than your original investment, even after taking into account the reinvestment of Fund dividends and distributions.

Large Shareholder Risk—To the extent a large proportion of the Common Shares are held by a small number of Common Shareholders (or a single shareholder), including affiliates of Nuveen Fund Advisors, the Fund is subject to the risk that these shareholders will purchase Common Shares in large amounts rapidly or unexpectedly. These transactions could adversely affect the ability of the Fund to conduct its investment program. Furthermore, it is possible that in response to a repurchase offer, the total amount of Common Shares tendered by a small number of Common Shareholders (or a single shareholder) may exceed the number of Common Shares that the Fund has offered to repurchase. If a repurchase offer is oversubscribed by Common Shareholders, the Fund will repurchase only a pro rata portion of shares tendered by each shareholder. See “Fund Level Risks—Repurchase Offers Risk” above.

Leverage Risk—The Fund’s use of leverage creates special risks for Common Shareholders, including potential interest rate risks and the likelihood of greater volatility of NAV and Common Share distributions. For example, dividends payable with respect to any Preferred Shares outstanding will generally be based on shorter-term interest rates that would be periodically reset. If shorter-term interest rates rise relative to the rate of return on the Fund’s portfolio, the interest and other costs to the Fund of leverage (including the dividend rate on any outstanding Preferred Shares), could exceed the rate of return on the investments held by the Fund, thereby reducing return to Common Shareholders. The use of leverage in a declining market will likely cause a greater decline in Common Share NAV than if the Fund were not to have used leverage. The Fund will pay (and only the Common Shareholders will bear) any costs and expenses relating to the Fund’s use of leverage, which will result in a reduction in the NAV of the Common Shares. Therefore, there can be no assurance that the Fund’s use of leverage will result in a higher yield on the Common Shares, and it may result in losses. Nuveen Fund Advisors may, based on its assessment of market conditions and the composition of the Fund’s holdings, increase or decrease the amount of leverage. Such changes may impact the Fund’s distributions. There is no assurance that the Fund’s use of leverage will be successful. See “Leverage.”

The Fund is required to satisfy certain asset coverage requirements in connection with its use of Preferred Shares, including those imposed by regulatory and/or contractual requirements. Accordingly, any decline in the value of the Fund’s investments could result in the risk that the Fund will fail to meet its asset coverage requirements for any such Preferred Shares. In order to prevent the Fund from failing to satisfy such requirements, the Fund might need to dispose of investments at inopportune times, which may result in losses to the Fund or additional taxable distributions to Common Shareholders in the event such distributions result in gains to the Fund.

Certain types of leverage may result in the Fund being subject to certain covenants, asset coverage or other portfolio composition limits by its lenders, debt or preferred securities purchasers, rating agencies that may rate the debt or preferred securities, or reverse repurchase counterparties. Such limitations may be more stringent than those imposed by the 1940 Act and may impact whether the Fund is able to maintain its desired amount of leverage. In addition, whenever the Fund incurs borrowings and/or preferred shares are outstanding, Common Shareholders will not be entitled to receive any cash distributions from the Fund unless all interest on such borrowings has been paid and all accumulated dividends on preferred shares have been paid, unless asset coverage (as defined in the 1940 Act) with respect to any borrowings would be at least 300% after giving effect to the distributions and asset coverage (as defined in the 1940 Act) with respect to preferred shares would be at least 200% after giving effect to the distributions.

The Fund may seek to refinance its leverage over time, in the ordinary course, as current forms of leverage mature or it is otherwise desirable to refinance; however, the form that such leverage will take cannot be predicted at this time. If the Fund is unable to replace existing leverage on comparable terms, its costs of leverage will increase. Accordingly, there is no assurance that the use of leverage may result in a higher yield or return to common shareholders.

The Fund pays a management fee to Nuveen Fund Advisors for investment advisory services, which in turn pays a portion of its fee to Nuveen Asset Management for investment sub-advisory services, based on a percentage of the Fund’s Managed Assets. Nuveen Fund Advisors and Nuveen Asset Management will base the decision regarding whether and how much leverage to use for the Fund based on their assessment of whether such use of leverage is in the best interests of the Fund. However, the fact that a decision to employ or increase the Fund’s leverage will have the effect, all other things being equal, of increasing Managed Assets and therefore Nuveen Fund Advisors’ and Nuveen Asset Management’s fees means that they may have a conflict of interest in determining whether to use or increase leverage. Nuveen Fund Advisors and Nuveen Asset Management will seek to manage that potential conflict by leveraging the Fund (or increasing such leverage) only when they determine that such action is in the best interests of the Fund, and by periodically reviewing the Fund’s performance and use of leverage with the Board of Trustees.

Repurchase Offers Risk—As described under “Periodic Repurchase Offers”, the Fund is an “interval fund” and, in order to provide liquidity to Common Shareholders, the Fund, subject to applicable law, intends to conduct quarterly repurchase offers of the Fund’s outstanding Common Shares at NAV, subject to approval of the Board of Trustees. In each quarter, such repurchase offers will be for at least 5% of its outstanding Common Shares at NAV, pursuant to Rule 23c-3 under the 1940 Act.

The Fund currently expects to conduct quarterly repurchase offers for 7.5% of its outstanding Common Shares under ordinary circumstances. The Fund believes that these repurchase offers are generally beneficial to the Fund’s Common Shareholders, and repurchases generally will be funded from available cash or sales of portfolio securities. However, repurchase offers and the need to fund repurchase obligations may affect the ability of the Fund to be fully invested or force the Fund to maintain a higher percentage of its assets in liquid investments, which may harm the Fund’s investment performance. Moreover, diminution in the size of the Fund through repurchases may result in untimely sales of portfolio securities (with associated imputed transaction costs, which may be significant), and may limit the ability of the Fund to participate in new investment opportunities or to achieve its investment objectives. The Fund may accumulate cash by holding back (i.e., not reinvesting) payments received in connection with the Fund’s investments. The Fund believes that payments received in connection with the Fund’s investments will generate sufficient cash to meet the maximum potential amount of the Fund’s repurchase obligations. If at any time cash and other liquid assets held by the Fund are not sufficient to meet the Fund’s repurchase obligations, the Fund intends, if necessary, to sell investments. If the Fund employs leverage, repurchases of Common Shares would compound the adverse effects of leverage in a declining market. In addition, if the Fund borrows to finance repurchases, interest on that borrowing will negatively affect Common Shareholders who do not tender their Common Shares by increasing the Fund’s expenses and reducing any net investment income. If a repurchase offer is oversubscribed, the Board of Trustees may determine to increase the amount repurchased by up to 2% of the Fund’s outstanding Common Shares as of the date of the Repurchase Request Deadline. In the event that the Board of Trustees determines not to repurchase more than the repurchase offer amount, or if Common Shareholders tender more than the repurchase offer amount plus 2% of the Fund’s outstanding Common Shares as of the date of the Repurchase Request Deadline, the Fund will repurchase the Common Shares tendered on a pro rata basis, and Common Shareholders will have to wait until the next repurchase offer to make another repurchase request. As a result, Common Shareholders may be unable to liquidate all or a given percentage of their investment in the Fund during a particular repurchase offer. Some Common Shareholders, in anticipation of proration, may tender more Common Shares than they wish to have repurchased in a particular quarter, thereby increasing the likelihood that proration will occur. A Common Shareholder may be subject to market and other risks, and the NAV of Common Shares tendered in a repurchase offer may decline between the Repurchase Request Deadline and the date on which the NAV for tendered Common Shares is determined. In addition, the repurchase of Common Shares by the Fund may be a taxable event to Common Shareholders.

While the Fund anticipates having enough cash on hand to fund share repurchases, it may need to sell securities in order to generate enough cash to fund share repurchases. This may cause the Fund to have a higher portfolio turnover rate than is generally anticipated. A higher portfolio turnover rate may result in higher taxes to Fund investors. This is because the sale of securities may accelerate the recognition of capital gains by the Fund (if the Fund’s basis in securities sold is less than the proceeds from the sale of the security) which may be distributed to investors, and it is more likely that such gains will be taxable as short-term capital gains rather than long-term capital gains that are taxable at lower rates.

If shares tendered by an investor are repurchased by the Fund, it will be a taxable transaction to the investor either in the form of a “sale or exchange” which would be taxable to an investor at capital gain tax rates, assuming such shares are held as a capital asset, or, under certain circumstances, a “dividend” which would be taxable to an investor at ordinary income tax rates. See “Tax Matters—Sale, Exchange of Liquidation of Fund Shares” in the SAI for additional information.

Other Risks

Certain Affiliations—Certain broker-dealers may be considered to be affiliated persons of the Fund, Nuveen Fund Advisors, Nuveen Asset Management, Nuveen and/or TIAA. Absent an exemption from the SEC or other regulatory relief, the Fund generally is precluded from effecting certain principal transactions with affiliated brokers, and its ability to purchase securities being underwritten by an affiliated broker or a syndicate including an affiliated broker, or to utilize affiliated brokers for agency transactions, is subject to restrictions. The Fund has not applied for and does not currently intend to apply for such relief. This could limit the Fund’s ability to engage in securities transactions and take advantage of market opportunities.

Counterparty Risk—The Fund will be subject to credit risk with respect to the counterparties to the derivative transactions entered into by the Fund. Changes in the credit quality of the companies that serve as the Fund’s counterparties with respect to derivatives transactions may affect the value of those instruments. Because certain derivative transactions in which the Fund may engage may be traded between counterparties based on contractual relationships, the Fund is subject to the risk that a counterparty will not perform its obligations under the related contracts. If a counterparty becomes bankrupt or otherwise becomes unable to perform its obligations due to financial difficulties the Fund may sustain losses (including the full amount of its investment), may be unable to liquidate a derivatives position or may experience significant delays in obtaining any recovery in bankruptcy or other reorganization proceedings. By entering into derivatives transactions, the Fund assumes the risk that its counterparties could experience such financial hardships. Although the Fund intends to enter into transactions only with counterparties that Nuveen Fund Advisors believes to be creditworthy, there can be no assurance that a counterparty will not default and that the Fund will not sustain a loss on a transaction. In the event of a counterparty’s bankruptcy or insolvency, any collateral posted by the Fund in connection with a derivatives transaction may be subject to the conflicting claims of that counterparty’s creditors, and the Fund may be exposed to the risk of a court treating the Fund as a general unsecured creditor of the counterparty, rather than as the owner of the collateral.

The counterparty risk for cleared derivatives is generally lower than for uncleared OTC derivative transactions. In a cleared derivative transaction, generally, a clearing organization becomes substituted for each counterparty to a cleared derivative contract and each party to a trade looks only to the clearing organization for performance of financial obligations under the derivative contract. In effect, the clearing organization guarantees a party’s performance under the contract. However, there can be no assurance that a clearing organization, or its members, will satisfy its obligations to the Fund, or that the Fund would be able to recover the full amount of assets deposited on its behalf with the clearing organization in the event of the default by the clearing organization or the Fund’s clearing broker. In addition, cleared derivative transactions benefit from daily marking-to-market and settlement, and segregation and minimum capital requirements applicable to intermediaries. Uncleared OTC derivative transactions generally do not benefit from such protections. As a result, for uncleared OTC derivative transactions, there is the risk that a counterparty will not settle a transaction in accordance with its terms and conditions because of a dispute over the terms of the contract (whether or not bona fide) or because of a credit or liquidity problem, thus causing the Fund to suffer a loss. This risk is heightened for contracts with longer maturities where events may intervene to prevent settlement, or where the Fund has concentrated its transactions with a single or small group of counterparties.

Cybersecurity Risk—Technology, such as the internet, has become more prevalent in the course of business, and as such, the Fund and its service providers are susceptible to operational and information security risk resulting from cyber incidents. Cyber incidents refer to both intentional attacks and unintentional events including: processing errors, human errors, technical errors including computer glitches and system malfunctions, inadequate or failed internal or external processes, market-wide technical-related disruptions, unauthorized access to digital systems (through “hacking” or malicious software coding), computer viruses, and cyber-attacks which shut down, disable, slow or otherwise disrupt operations, business processes or website access or functionality (including denial of service attacks). Geopolitical tensions may, from time to time, increase the scale and sophistication of deliberate cyberattacks. Cyber incidents could adversely impact the Fund and cause the Fund to incur financial loss and expense, as well as face exposure to regulatory penalties, reputational damage, and additional compliance costs associated with corrective measures. Cyber incidents may cause a Fund or its service providers to lose proprietary information, suffer data corruption, lose operational capacity or fail to comply with applicable privacy and other laws. Among other potentially harmful effects, cyber incidents also may result in theft, unauthorized monitoring and failures in the physical infrastructure or operating systems that support the Fund and its service providers. In addition, substantial costs may be incurred in order to prevent any cyber incidents in the future. While the Fund’s service providers have established business continuity plans in the event of, and risk management systems to prevent, such cyber incidents, there are inherent limitations in such plans and systems including the possibility that certain risks have not been identified. Furthermore, the Fund cannot control the cybersecurity plans and systems put in place by its service providers or any other third parties whose operations may affect the Fund.

Deflation Risk—Deflation risk is the risk that prices throughout the economy decline over time. Deflation may have an adverse effect on the creditworthiness of issuers and may make issuer default more likely, which may result in a decline in the value of the Fund’s portfolio.

Direct Lending Risk—The Fund may engage in direct lending. Direct loans between the Fund and a borrower may not be administered by an underwriter or agent bank. The Fund may provide financing to commercial borrowers directly or through companies affiliated with the Fund. The terms of the direct loans are negotiated with borrowers in private transactions. Furthermore, a direct loan may be secured or unsecured. The Fund will rely primarily upon the creditworthiness of the borrower and/or any collateral for payment of interest and repayment of principal. Direct loans may subject the Fund to liquidity risk, interest rate risk, and borrower default or insolvency. Direct loans are not publicly traded and may not have a secondary market which may have an adverse impact on the ability of the Fund to dispose of a direct loan and/or value the direct loan. The Fund’s performance may be impacted by the Fund’s ability to lend on favorable terms as the Fund may be subject to increased competition or a reduced supply of qualifying loans which could lead to lower yields and reduce Fund performance.

As part of its lending activities, the Fund may originate loans to companies that are experiencing significant financial or business difficulties, including companies involved in bankruptcy or other reorganization and liquidation proceedings. Although the terms of such financing may result in significant financial returns to the Fund, they involve a substantial degree of risk. The level of analytical sophistication, both financial and legal, necessary for successful financing to companies experiencing significant business and financial difficulties is unusually high. Different types of assets may be used as collateral for the Fund’s loans and, accordingly, the valuation of and risks associated with such collateral will vary by loan. There is no assurance that the Fund will correctly evaluate the value of the assets collateralizing the Fund’s loans or the prospects for a successful reorganization or similar action. In any reorganization or liquidation proceeding relating to a borrower that the Fund is lending money to, the Fund may lose all or part of the amounts advanced to the borrower or may be required to accept collateral with a value less than the amount of the loan advanced by the Fund to the borrower. Furthermore, in the event of a default by a borrower, the Fund may have difficulty disposing of the assets used as collateral for a loan. To the extent the Fund seeks to engage in direct lending, the Fund will be subject to enhanced risks of litigation, regulatory actions and other proceedings. As a result, the Fund may be required to pay legal fees, settlement costs, damages, penalties or other charges, any or all of which could materially adversely affect the Fund and its holdings.

Economic and Political Events Risk—The Fund may be more sensitive to adverse economic, business or political developments if it invests a substantial portion of its assets in the municipal securities of similar projects (such as those relating to the education, health care, housing, transportation, or utilities industries), industrial development bonds, or in particular types of municipal securities (such as general obligation bonds, private activity bonds or moral obligation bonds). Such developments may adversely affect a specific industry or local political and economic conditions, and thus may lead to declines in the creditworthiness and value of such municipal securities.

Global Economic Risk—National and regional economies and financial markets are becoming increasingly interconnected, which increases the possibilities that conditions in one country, region or market might adversely impact issuers in a different country, region or market. Changes in legal, political, regulatory, tax and economic conditions may cause fluctuations in markets and asset prices around the world, which could negatively impact the value of the Fund’s investments. Major economic or political disruptions, particularly in large economies, may have global negative economic and market repercussions. Additionally, instability in various countries, war, natural and environmental disasters, the spread of infectious illnesses or other public health emergencies, terrorist attacks in the United States and around the world, growing social and political discord in the United States, debt crises, the response of the international community—through economic sanctions and otherwise—to international events, further downgrade of U.S. government securities, changes in the U.S. president or political shifts in Congress, trade disputes and other similar events may adversely affect the global economy and the markets and issuers in which the Fund invests. These events could reduce consumer demand or economic output, result in market closure, travel restrictions or quarantines, and generally have a significant impact on the global economy. These events could also impair the information technology and other operational systems upon which the Fund’s service providers, including the Fund’s sub-adviser, rely, and could otherwise disrupt the ability of employees of the Fund’s service providers to perform essential tasks on behalf of the Fund.

The Fund does not know and cannot predict how long the securities markets may be affected by these events, and the future impact of these and similar events on the global economy and securities markets is uncertain. The Fund may be adversely affected by abrogation of international agreements and national laws which have created the market instruments in which the Fund may invest, failure of the designated national and international authorities to enforce compliance with the same laws and agreements, failure of local, national and international organizations to carry out the duties prescribed to them under the relevant agreements, revisions of these laws and agreements which dilute their effectiveness or conflicting interpretation of provisions of the same laws and agreements.

Governmental and quasi-governmental authorities and regulators throughout the world have in the past responded to major economic disruptions with a variety of significant fiscal and monetary policy changes, including but not limited to, direct capital infusions into companies, new monetary programs and dramatically lower interest rates. An unexpected or quick reversal of these policies, or the ineffectiveness of these policies, could increase volatility in securities markets, which could adversely affect the Fund’s investments.

Income Risk—The Fund’s level of current income could decline due to falling market interest rates. This is because, in a falling interest rate environment, the Fund generally will have to invest the proceeds from sales of Fund shares, as well as the proceeds from maturing portfolio securities, in lower-yielding securities.

Legislation and Regulatory Risk—At any time after the date of this prospectus, 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 objectives.

Litigation Risk—From time to time, the Fund, Nuveen Fund Advisors and Nuveen Asset Management may be subject to pending or threatened litigation or regulatory action. Some of these claims may result in significant defense costs and potentially significant judgments. The ultimate outcome of any potential litigation or regulatory action or any claims that may arise in the future cannot be predicted and the reputation of the Fund, Nuveen Fund Advisors and/or Nuveen Asset Management could be damaged as a result. Certain litigation or regulatory scrutiny could materially adversely affect the Fund. The resolution of certain claims may result in significant fines, judgments, or settlements, which, if partially or completely uninsured, could adversely impact the Fund or the ability of Nuveen Fund Advisors and/or Nuveen Asset Management to perform their duties to the Fund.

Other Investment Companies Risk—Investing in an investment company exposes the Fund to all of the risks of that investment company’s investments. The Fund, as a holder of the securities of other investment companies, will bear its pro rata portion of the other investment companies’ expenses, including advisory fees. These expenses are in addition to the direct expenses of the Fund’s own operations. As a result, the cost of investing in investment company shares may exceed the costs of investing directly in its underlying investments. In addition, securities of other investment companies may be leveraged. As a result, the Fund may be directly exposed to leverage through an investment in such securities and therefore magnify the Fund’s leverage risk. With respect to ETF’s, an ETF that is based on a specific index may not be able to replicate and maintain exactly the composition and relative weighting of securities in the index. The value of an ETF based on a specific index is subject to change as the values of its respective component assets fluctuate according to market volatility. ETFs typically rely on a limited pool of authorized participants to create and redeem shares, and an active trading market for ETF shares may not develop or be maintained. The market value of shares of ETFs and closed-end funds may differ from their NAV.

Potential Conflicts of Interest Risk—Nuveen Fund Advisors and Nuveen Asset Management each provide a wide array of portfolio management and other asset management services to a mix of clients and may engage in ordinary course activities in which their respective interests or those of their clients may compete or conflict with those of the Fund. In certain circumstances, and subject to its fiduciary obligations under the Investment Advisers Act of 1940, as amended (“Advisers Act”), Nuveen Fund Advisors or Nuveen Asset Management may have to allocate a limited investment opportunity among its clients, which include closed-end funds, open-end funds, and other commingled funds, separate accounts, and structured products. Nuveen Fund Advisors and Nuveen Asset Management have each adopted policies and procedures designed to address such situations and other potential conflicts of interests.

Recent Market Conditions Risk—Periods of unusually high financial market volatility and restrictive credit conditions, at times limited to a particular sector or geographic area, have occurred in the past and may be expected to recur in the future. Some countries, including the United States, have adopted or have signaled protectionist trade measures, including the imposition of tariffs, relaxation of the financial industry regulations that followed the financial crisis, and/or reductions to corporate taxes. The scope of these policy changes is still developing, but the equity and debt markets may react strongly to expectations of change, which could increase volatility, particularly if a resulting policy runs counter to the market’s expectations. The outcome of such changes cannot be foreseen at the present time. In addition, geopolitical and other risks, including environmental and public health risks, may add to instability in the world economy and markets generally. As a result of increasingly interconnected global economies and financial markets, the value and liquidity of the Fund’s investments may be negatively affected by events impacting a country or region, regardless of whether the Fund invests in issuers located in or with significant exposure to such country or region.

Ukraine has experienced ongoing military conflict, most recently in February 2022 when Russia invaded Ukraine; this conflict may expand and military attacks could occur elsewhere in Europe. Europe has also been struggling with mass migration from the Middle East and Africa. Additionally, in October 2023 armed conflict broke out between Israel and the militant group Hamas after Hamas infiltrated Israel’s southern border from the Gaza Strip. Israel has since declared war against Hamas and this conflict has escalated into a greater regional conflict. The ultimate effects of these events and other socio-political or geographical issues are not known but could profoundly affect global economies and markets.

The ongoing trade war between China and the United States, including the imposition of tariffs by each country on the other country’s products, has created a tense political environment. These actions may trigger a significant reduction in international trade, the oversupply of certain manufactured goods, substantial price reductions of goods and possible failure of individual companies and/or large segments of China’s export industry, which could have a negative impact on the Fund’s performance. U.S. companies that source material and goods from China and those that make large amounts of sales in China would be particularly vulnerable to an escalation of trade tensions. Uncertainty regarding the outcome of the trade tensions and the potential for a trade war could cause the U.S. dollar to decline against safe haven currencies, such as the Japanese yen and the euro. Events such as these and their consequences are difficult to predict and it is unclear whether further tariffs may be imposed or other escalating actions may be taken in the future. Beginning in early 2025, the United States also imposed tariffs on other countries, including Mexico and Canada. The possibility of additional tariffs being imposed or the outbreak of a trade war may adversely impact U.S. and international markets. Additionally, political uncertainty regarding U.S. policy, including the U.S. government’s approach to trade, may also impact the markets and the Fund’s performance.

The Federal Reserve (the “Fed”) has in the past sharply raised interest rates and has signaled an intention to maintain relatively higher interest rates until current inflation levels re-align with the Fed’s long-term inflation target. Changing interest rate environments impact the various sectors of the economy in different ways. For example, in March 2023, the Federal Deposit Insurance Corporation “FDIC” was appointed receiver for each of Silicon Valley Bank and Signature Bank, the second- and third-largest bank failures in U.S. history, which failures may be attributable, in part, to rising interest rates. Bank failures may have a destabilizing impact on the broader banking industry or markets generally.

The impact of these developments in the near- and long-term is unknown and could have additional adverse effects on economies, financial markets and asset valuations around the world.

Risks Related to the Fund’s Clearing Broker and Central Clearing Counterparty—The Commodity Exchange Act (the “CEA”) requires swaps and futures clearing brokers registered as “futures commission merchants” to segregate all funds received from customers with respect to any orders for the purchase or sale of U.S. domestic futures contracts and cleared swaps from the brokers’ proprietary assets. Similarly, the CEA requires each futures commission merchant to hold in separate secure accounts all funds received from customers with respect to any orders for the purchase or sale of foreign futures contracts and cleared swaps and segregate any such funds from the funds received with respect to domestic futures contracts. However, all funds and other property received by a clearing broker from its customers are held by the clearing broker on a commingled basis in an omnibus account and may be invested in certain instruments permitted under applicable regulations. There is a risk that assets deposited by the Fund with any swaps or futures clearing broker as margin for futures contracts or cleared swaps may, in certain circumstances, be used to satisfy losses of other clients of the Fund’s clearing broker. In addition, the assets of the Fund might not be fully protected in the event of the Fund’s clearing broker’s bankruptcy, as the Fund would be limited to recovering only a pro rata share of all available funds segregated on behalf of the clearing broker’s customers for the relevant account class.

Similarly, the CEA requires a clearing organization approved by the CFTC as a derivatives clearing organization to segregate all funds and other property received from a clearing member’s clients in connection with domestic cleared derivative contracts from any funds held at the clearing organization to support the clearing member’s proprietary trading. Nevertheless, all customer funds held at a clearing organization in connection with any futures contracts are held in a commingled omnibus account and are not identified to the name of the clearing member’s individual customers. All customer funds held at a clearing organization with respect to cleared swaps of customers of a clearing broker are also held in an omnibus account, but CFTC rules require that the clearing broker notify the clearing organization of the amount of the initial margin provided by the clearing broker to the clearing organization that is attributable to each customer. With respect to futures and options contracts, a clearing organization may use assets of a non-defaulting customer held in an omnibus account at the clearing organization to satisfy payment obligations of a defaulting customer of the clearing member to the clearing organization. With respect to cleared swaps, a clearing organization generally cannot do so, but may do so if the clearing member does not provide accurate reporting to the clearing organization as to the attribution of margin among its clients. Also, since clearing brokers generally provide to clearing organizations the net amount of variation margin required for cleared swaps for all of its customers in the aggregate, rather than the gross amount of each customer, the Fund is subject to the risk that a clearing organization will not make variation margin payments owed to the Fund if another customer of the clearing member has suffered a loss and is in default. As a result, in the event of a default or the clearing broker’s other clients or the clearing broker’s failure to extend its own funds in connection with any such default, the Fund may not be able to recover the full amount of assets deposited by the clearing broker on behalf of the Fund with the clearing organization.

Effects of Leverage [Text Block]

Effects of Leverage

The following table is furnished in response to requirements of the SEC. It is designed to illustrate the effects of leverage through the use of senior securities, as that term is defined under Section 18 of the 1940 Act, as well as certain other forms of leverage, such as reverse repurchase agreements and investments in inverse floating rate securities, on common share total return, assuming investment portfolio total returns (consisting of income and changes in the value of investments held in the Fund’s portfolio) of -10%, -5%, 0%, 5% and 10%. The table below reflects the Fund’s (i) continued use of leverage as of March 31, 2026 as a percentage of Managed Assets (including assets attributable to such leverage), (ii) the estimated annual effective interest expense rate payable by the Fund on such instruments (based on actual leverage costs incurred during the fiscal year ended March 31, 2026) as set forth in the table, and (iii) the annual return that the Fund’s portfolio must experience (net of expenses) in order to cover such costs of leverage based on such estimated annual effective interest expense rate. The information below does not reflect any Fund’s use of certain other forms of economic leverage achieved through the use of other instruments or transactions not considered to be senior securities under the 1940 Act, such as certain derivative instruments and investments in inverse floating rate securities.

The numbers are merely estimates, used for illustration. The costs of leverage may vary frequently and may be significantly higher or lower than the estimated rate. The assumed investment portfolio returns in the table below are hypothetical figures and are not necessarily indicative of the investment portfolio returns experienced or expected to be experienced by the Fund. Your actual returns may be greater or less than those appearing below.

Leverage as a Percentage of Total Managed Assets (Including Assets Attributable to Leverage)	29.58	%
Estimated Annual Effective Leverage Expense Payable on Leverage	3.57	%
Annual Return Fund Portfolio Must Experience (net of expenses) to Cover Estimated Annual Effective Interest Expense Rate on Leverage	1.05	%
Common Share Total Return for (10.00)% Assumed Portfolio Total Return	(15.70)	%
Common Share Total Return for (5.00)% Assumed Portfolio Total Return	(8.60)	%
Common Share Total Return for 0.00% Assumed Portfolio Total Return	(1.50)	%
Common Share Total Return for 5.00% Assumed Portfolio Total Return	5.60	%
Common Share Total Return for 10.00% Assumed Portfolio Total Return	12.70	%

Common Share total return is composed of two elements—the distributions paid by the Fund to holders of common shares (the amount of which is largely determined by the net investment income of the Fund after paying dividend payments on any preferred shares issued by the Fund and expenses on any forms of leverage outstanding) and gains or losses on the value of the securities and other instruments the Fund owns. As required by SEC rules, the table assumes that the Fund is more likely to suffer capital losses than to enjoy capital appreciation. For example, to assume a total return of 0%, the Fund must assume that the income it receives on its investments is entirely offset by losses in the value of those investments. This table reflects hypothetical performance of the Fund’s portfolio and not the actual performance of the Fund’s common shares, the value of which is determined by market forces and other factors. Should the Fund elect to add additional leverage to its portfolio, any benefits of such additional leverage cannot be fully achieved until the proceeds resulting from the use of such leverage have been received by the Fund and invested in accordance with the Fund’s investment objectives and policies. As noted above, the Fund’s willingness to use additional leverage, and the extent to which leverage is used at any time, will depend on many factors.

Common Shares

The Fund’s Declaration of Trust authorizes the issuance of an unlimited number of Common Shares. The Common Shares being offered have a par value of $0.01 per share and, subject to differences between classes, have equal rights to the payment of dividends and the distribution of assets upon liquidation of the Fund. The Fund is currently offering three classes of Common Shares: Class I Common Shares, Class A1 Common Shares and Class A2 Common Shares. The Fund may offer additional classes of Common Shares in the future pursuant to exemptive relief from the SEC. An investment in any share class of the Fund represents an investment in the same assets of the Fund. However, the ongoing fees and expenses for each share class may be different. The fees and expenses for the Fund are set forth in “Summary of Fund Expenses” above. Certain share class details are set forth in “Plan of Distribution” below. The Common Shares being offered will, when issued, be fully paid and, subject to matters discussed under “Certain Provisions in the Declaration of Trust and By-Laws,” non-assessable, and will have no preemptive or conversion rights, except as the Board of Trustees may otherwise determine, or rights to cumulative voting. The Declaration of Trust provides that each whole Common Share shall be entitled to one vote as to any matter on which it is entitled to vote and each fractional Common Share shall be entitled to a proportionate fractional vote. However, separate votes are taken by each class of Common Shares on matters affecting an individual class of Common Shares. The Fund does not intend to hold annual meetings of shareholders. If the Fund issues Preferred Shares, the Common Shareholders will not be entitled to receive any cash distributions from the Fund unless all accrued dividends on Preferred Shares have been paid, and unless asset coverage (as defined in the 1940 Act) with respect to Preferred Shares would be at least 200% after giving effect to the distributions. The Fund pays monthly distributions, typically on the first business day of the following month.

The Fund will make available unaudited reports at least semiannually and audited financial statements annually to all of its Common Shareholders.

The Common Shares are not, and are not expected to be, listed for trading on any national securities exchange nor is there expected to be any secondary trading market in the Common Shares.

The following provides information about the Fund’s outstanding Common Shares as of June 30, 2026:

Title of Class	Authorized Amount		Amount Held by the Fund or for its Account		Amount Outstanding
Class I Common Shares		Unlimited		0		35,391,575
Class A1 Common Shares		Unlimited		0		36,704,804
Class A2 Common Shares		Unlimited		0		28,513,245

Preferred Shares

The Fund’s Declaration of Trust authorizes the issuance of an unlimited number of Preferred Shares in one or more classes or series, with rights as determined by the Board of Trustees, by action of the Board of Trustees without the approval of the Common Shareholders. As of June 30, 2026, there were 1,295 Series A MuniFund Preferred Shares (the "Series A MFP Shares") and 1,450 Series B MuniFund Preferred Shares (the "Series B MFP Shares"). The Series A MFP Shares and Series B MFP Shares have various rights that were approved by the Board without the approval of Common Shareholders, which are specified in the Fund’s Declaration of Trust. The below generally describes the rights of the holders of Preferred Shares, although the terms of any Preferred Shares that may be issued by the Fund may be the same as, or different from, the terms described below, subject to applicable law and the Declaration.

Under the 1940 Act, the Fund is not permitted to issue “senior securities” that are Preferred Shares if, immediately after the issuance of Preferred Shares, the asset coverage ratio would be less than 200%. See “Leverage.” Additionally, the Fund will generally not be permitted to purchase any of its Common Shares or declare dividends (except a dividend payable in Common Shares) or other distributions on its Common Shares unless, at the time of such purchase or declaration, the asset coverage ratio with respect to such Preferred Shares, after taking into account such purchase or distribution, is at least 200%.

Any Preferred Shares issued by the Fund will have priority over the Common Shares. For so long as any Preferred Shares are outstanding, the Fund will not: (1) declare or pay any dividend or other distribution (other than a dividend or distribution paid in Common Shares) in respect of the Common Shares, (2) call for redemption, redeem, purchase or otherwise acquire for consideration any Common Shares, or (3) pay any proceeds of the liquidation of the Fund in respect of the Common Shares, unless, in each case, (A) immediately thereafter, the Fund shall be in compliance with the 200% asset coverage limitations set forth under the 1940 Act after deducting the amount of such dividend or other distribution or redemption or purchase price or liquidation proceeds and (B) all cumulative dividends and other distributions of shares of all series of Preferred Shares of the Fund due on or prior to the date of the applicable dividend, distribution, redemption, purchase or acquisition shall have been declared and paid.

Distribution Preference. Any Preferred Shares would have complete priority over the Common Shares as to distribution of assets.

Liquidation Preference. In the event of any voluntary or involuntary liquidation, dissolution or winding up of the affairs of the Fund, holders of Preferred Shares would be entitled to receive a preferential liquidating distribution (expected to equal the original purchase price per share plus accumulated and unpaid dividends thereon, whether or not earned or declared) before any distribution of assets is made to Common Shareholders. After payment of the full amount of the liquidating distribution to which they are entitled, holders of Preferred Shares will not be entitled to any further participation in any distribution of assets by the Fund. A consolidation or merger of the Fund with or into another entity or a sale of all or substantially all of the assets of the Fund shall not be deemed to be a liquidation, dissolution or winding up of the Fund.

Voting Rights. In connection with any issuance of Preferred Shares, the Fund must comply with Section 18(i) of the 1940 Act, which requires, among other things, that Preferred Shares be voting shares and have equal voting rights with Common Shares. Except as otherwise indicated in the SAI and except as otherwise required by applicable law, holders of Preferred Shares would vote together with Common Shareholders as a single class.

In connection with the election of the Fund’s trustees, holders of Preferred Shares, voting as a separate class, would be entitled to elect two of the Fund’s trustees, and the remaining trustees would be elected by Common Shareholders and holders of Preferred Shares, voting together as a single class. In addition, if at any time dividends on the Fund’s outstanding Preferred Shares would be unpaid in an amount equal to two full years’ dividends thereon, the holders of all outstanding Preferred Shares, voting as a separate class, would be entitled to elect a majority of the Fund’s trustees until all dividends in arrears have been paid or declared and set apart for payment.

The affirmative vote of the holders of a majority of the Fund’s outstanding Preferred Shares of any class or series, as the case may be, voting as a separate class, would be required to, among other things, (1) take certain actions that would affect the preferences, rights, or powers of such class or series or (2) authorize or issue any class or series ranking prior to the Preferred Shares. Except as may otherwise be required by law, (1) the affirmative vote of the holders of at least two-thirds of the Fund’s Preferred Shares outstanding at the time, voting as a separate class, would be required to approve any conversion of the Fund from a closed-end to an open-end investment company and (2) the affirmative vote of the holders of at least two-thirds of the outstanding Preferred Shares, voting as a separate class, would be required to approve any plan of reorganization (as such term is used in the 1940 Act) adversely affecting such shares; provided however, that such separate class vote would be a majority vote if the action in question has previously been approved, adopted or authorized by the affirmative vote of two-thirds of the total number of trustees fixed in accordance with the Declaration or the By-laws. The affirmative vote of the holders of a majority of the outstanding Preferred Shares, voting as a separate class, would be required to approve any action not described in the preceding sentence requiring a vote of security holders under Section 13(a) of the 1940 Act including, among other things, changes in the Fund’s investment objectives or changes in the investment restrictions described as fundamental policies under “Investment Restrictions” in the SAI. The class or series vote of holders of Preferred Shares described above would in each case be in addition to any separate vote of the requisite percentage of Common Shares and Preferred Shares necessary to authorize the action in question.

The foregoing voting provisions would not apply with respect to the Fund’s Preferred Shares if, at or prior to the time when a vote was required, such shares would have been (1) redeemed or (2) called for redemption and sufficient funds would have been deposited in trust to effect such redemption.

Redemption, Purchase and Sale of Preferred Shares. The terms of the Preferred Shares may provide that they are redeemable by the Fund at certain times, in whole or in part, at the original purchase price per share plus accumulated dividends, that the Fund may tender for or purchase Preferred Shares and that the Fund may subsequently resell any shares so tendered for or purchased. Any redemption or purchase of Preferred Shares by the Fund would reduce the leverage applicable to Common Shares, while any resale of such shares by the Fund would increase such leverage.

Title of Class	Authorized Amount		Amount Held by the Fund or for its Account		Amount Outstanding
Series A MFP Shares		Unlimited		0		1,295
Series B MFP Shares		Unlimited		0		1,450

Long Term Debt [Table Text Block]

Senior Securities Representing Indebtedness

The Fund’s Declaration of Trust authorizes the Fund, without approval of the Common Shareholders, to borrow money. In this connection, the Fund may issue notes or other evidence of indebtedness (including bank borrowings or commercial paper) and may secure any such debt by mortgaging, pledging or otherwise subjecting as security the Fund’s assets. In connection with such borrowing, the Fund may be required to maintain minimum average balances with the lender or to pay a commitment or other fee to maintain a line of credit. Any such requirements will increase the cost of borrowing over the stated interest rate. Under the requirements of the 1940 Act, the Fund, immediately after issuing any such senior security representing indebtedness, must have an “asset coverage” of at least 300%. See “Leverage.” Certain types of debt may result in the Fund being subject to certain restrictions imposed by guidelines of one or more rating agencies which may issue ratings for commercial paper or notes issued by the Fund. Such restrictions may be more stringent than those imposed by the 1940 Act.

The rights of lenders to the Fund to receive interest on and repayment of principal of any such debt will be senior to those of the Common Shareholders, or preferred shareholders, if any, and the terms of any such debt may contain provisions which limit certain activities of the Fund, including the payment of dividends to Common Shareholders in certain circumstances. Any debt will likely be ranked senior or equal to all other existing and future debt of the Fund.

Notwithstanding the foregoing, at any time, should the Fund have outstanding any “senior securities representing indebtedness,” the Fund may not purchase, redeem or acquire any of its Common Shares or Preferred Shares unless at the time of such purchase, redemption, or acquisition, the asset coverage of such senior securities representing indebtedness pursuant to the 1940 Act (determined after deducting the acquisition price of such Common or Preferred Shares) is at least 300%. Additionally, the Fund will generally not be permitted to declare dividends or other distributions on its Common Shares unless, at the time of such declaration or distribution, the asset coverage applicable to such senior securities representing indebtedness pursuant to the 1940 Act (determined after deducting the dividend or distribution amount) is at least 300%. Further, the 1940 Act (in certain circumstances) grants to the holders of such senior securities representing indebtedness (1) the right to declare a default, and (2) certain voting rights, in the event that specified asset coverage levels on such senior debt securities are not maintained. Specifically, in accordance with Section 18 of the 1940 Act, it shall be deemed an event of default if the asset coverage of such senior debt securities falls below 100% on the last business day of each month for twenty-four consecutive calendar months. In addition, senior debt security holders will be permitted to elect at least a majority of the Fund’s trustees if the asset coverage of such senior debt securities falls below 100% on the last business day of each month for a twelve calendar month period. These voting rights will continue until such asset coverage equals at least 110% on the last business day of each month for three consecutive calendar months. The provisions described in this paragraph do not apply, however, to bank or other privately arranged debt that is not intended to be publicly distributed. In addition to the foregoing asset coverage requirements, the Fund will comply with the requirements set forth in Rule 23c-3 under the 1940 Act related to senior securities.

Inter-Fund Borrowing and Lending. The SEC has granted an exemptive order permitting the Nuveen registered open-end and closed-end funds, including the Fund, to participate in an inter-fund lending facility whereby those funds may directly lend to and borrow money from each other for temporary purposes (e.g., to satisfy redemption requests or when a sale of securities “fails,” resulting in an unanticipated cash shortfall) (the “Inter-Fund Program”). The closed-end Nuveen funds will participate only as lenders, and not as borrowers, in the Inter-Fund Program because such closed-end funds rarely, if ever, need to borrow cash to meet the Fund’s obligations. The Inter-Fund Program is subject to a number of conditions, including, among other things, the requirements that (1) no fund may borrow or lend money through the Inter-Fund Program unless it receives a more favorable interest rate than is typically available from a bank or other financial institution for a comparable transaction; (2) no fund may borrow on an unsecured basis through the Inter-Fund Program unless the fund’s outstanding borrowings from all sources immediately after the inter-fund borrowing total 10% or less of its total assets; provided that if the borrowing fund has a secured borrowing outstanding from any other lender, including but not limited to another fund, the inter-fund loan must be secured on at least an equal priority basis with at least an equivalent percentage of collateral to loan value; (3) if a fund’s total outstanding borrowings immediately after an inter-fund borrowing would be greater than 10% of its total assets, the fund may borrow through the inter-fund loan on a secured basis only; (4) no fund may lend money if the loan would cause its aggregate outstanding loans through the Inter-Fund Program to exceed 15% of its net assets at the time of the loan; (5) a fund’s inter-fund loans to any one fund shall not exceed 5% of the lending fund’s net assets; (6) the duration of inter-fund loans will be limited to the time required to receive payment for securities sold, but in no event more than seven days; and (7) each inter-fund loan may be called on one business days’ notice by a lending fund and may be repaid on any day by a borrowing fund. In addition, a Nuveen fund may participate in the Inter-Fund Program only if and to the extent that such participation is consistent with the fund’s investment objective(s) and investment policies. The Board of Trustees of the Nuveen Funds is responsible for overseeing the Inter-Fund Program. The limitations detailed above and the other conditions of the SEC exemptive order permitting the Inter-Fund Program are designed to minimize the risks associated with Inter-Fund Program for both the lending fund and the borrowing fund. However, no borrowing or lending activity is without risk. When a fund borrows money from another fund, there is a risk that the loan could be called on one day’s notice or not renewed, in which case the fund may have to borrow from a bank at a higher rate or take other actions to payoff such loan if an inter-fund loan is not available from another fund. Any delay in repayment to a lending fund could result in a lost investment opportunity or additional borrowing costs.
