Investment Objectives and Policies

Please refer to the section of the Fund’s most recent annual report on Form N-CSR entitled “Shareholder Update—Current Investment Objectives, Investment Policies and Principal Risks of the Fund—Investment Objectives” and “—Investment Policies,” as such investment objectives and investment policies may be supplemented from time to time, which are incorporated by reference herein, for a discussion of the Fund’s investment objectives and policies.

There can be no assurance that such strategies will be successful. For a more complete discussion of the Fund’s portfolio composition and its corresponding risks, see “The Fund’s Investments” and “Risk Factors.”

Investment Adviser

Nuveen Fund Advisors, LLC (“Nuveen Fund Advisors”), the Fund’s investment adviser, is responsible for overseeing the Fund’s overall investment strategy and its implementation. Nuveen Fund Advisors offers advisory and investment management services to a broad range of investment company clients. Nuveen Fund Advisors has overall responsibility for management of the Fund, oversees the management of the Fund’s portfolio, manages the Fund’s business affairs and provides certain clerical, bookkeeping and other administrative services. Nuveen Fund Advisors is located at 333 West Wacker Drive, Chicago, Illinois 60606. Nuveen Fund Advisors is an indirect subsidiary of Nuveen, LLC (“Nuveen”), the investment management arm of Teachers Insurance and Annuity Association of America (“TIAA”). TIAA is a life insurance company founded in 1918 by the Carnegie Foundation for the Advancement of Teaching and is the companion organization of College Retirement Equities Fund. As of March 31, 2024, Nuveen managed approximately $1.2 trillion in assets, of which approximately $143.2 billion was managed by Nuveen Fund Advisors.

Sub-Adviser

Nuveen Asset Management, LLC (“Nuveen Asset Management”) serves as the Fund’s sub-adviser. Nuveen Asset Management, a registered investment adviser, is a wholly-owned subsidiary of Nuveen Fund Advisors. Nuveen Asset Management oversees the day-to-day investment operations of the Fund.

Use of Leverage

The Fund uses leverage to pursue its investment objectives. The Fund may use leverage to the extent permitted by the Investment Company Act of 1940, as amended (the “1940 Act”). The Fund may source leverage through a number of methods, including reverse repurchase agreements (effectively a secured borrowing), investments in inverse floating rate securities of tender option bond trusts, borrowings (including loans from financial institutions), issuances of debt securities, and issuances of Preferred Shares. The Fund may also use other forms of leverage including, but not limited to, portfolio investments that have the economic effect of leverage.

Currently, the Fund employs leverage through its use of reverse repurchase agreements. The Fund also currently invests in residual interest certificates of tender option bond trusts, also called inverse floating rate securities, that have the economic effect of leverage because the Fund’s investment exposure to the underlying bonds held by the Fund have been effectively financed by the Fund’s issuance of floating rate certificates. As of May 31, 2024, the Fund’s leverage through reverse repurchase agreements and through investments in inverse floating rate securities was approximately 41% of its Managed Assets.

The Fund may also borrow for temporary purposes as permitted by the 1940 Act.

The Fund may reduce or increase leverage based upon changes in market conditions and anticipates that its leverage ratio will vary from time to time based upon variations in the value of the Fund’s holdings. So long as the rate of net income received on the Fund’s investments exceeds the then current expense on any leverage, leverage will generate more net income than if the Fund had not used leverage. If so, the excess net income will be available to pay higher distributions to holders of Common Shares (“Common Shareholders”). However, if the rate of net income received from the Fund’s portfolio investments is less than the then current expense on outstanding leverage, the Fund may be required to utilize other Fund assets to make expense payments on outstanding leverage, which may result in a decline in Common Share NAV and reduced net investment income available for distribution to Common Shareholders.

The Fund pays a management fee to Nuveen Fund Advisors (which in turn pays a portion of its fee to Nuveen Asset Management) based on a percentage of Managed Assets. Managed Assets for this purpose includes the proceeds realized and managed from the Fund’s use of leverage as set forth in the Fund’s investment management agreement. Because Managed Assets include the Fund’s net assets as well as assets that are attributable to the Fund’s use of leverage, it is anticipated that the Fund’s Managed Assets will be greater than its net assets. Nuveen Fund Advisors and Nuveen Asset Management are responsible for using leverage to pursue the Fund’s investment objectives, and base their decision regarding whether and how much leverage to use for the Fund on their assessment of whether such use of leverage will advance the Fund’s investment objectives. However, 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. Thus, Nuveen Fund Advisors and Nuveen Asset Management may have a conflict of interest in determining whether the Fund should use or increase leverage. Nuveen Fund Advisors and Nuveen Asset Management will seek to manage that potential conflict by only employing or increasing the Fund’s use of leverage when they determine that such increase is in the best interest of the Fund and is consistent with the Fund’s investment objectives, and by periodically reviewing the Fund’s performance and use of leverage with the Fund’s Board of Trustees (the “Board”).

The use of leverage creates additional risks for Common Shareholders, including increased variability of the Fund’s NAV, net income and distributions in relation to market changes. There is no assurance that the Fund will continue to use leverage or that the Fund’s use of leverage will work as planned or achieve its goals.

Distributions

The Fund pays regular monthly cash distributions to Common Shareholders (stated in terms of a fixed cents per Common Share dividend distribution rate which may be set from time to time). The Fund intends to distribute all or substantially all of its net investment income each year through its regular monthly distributions and to distribute realized capital gains at least annually. In addition, in any monthly period, to maintain its declared per common share distribution amount, the Fund may distribute more or less than its net investment income during the period. In the event the Fund distributes more than its net investment income, such distributions may also include realized gains and/or a return of capital. To the extent that a distribution includes a return of capital the NAV per share may erode. If a distribution includes anything other than net investment income, the Fund provides a notice of the best estimate of its distribution sources at the time. See “Distributions.”

The Fund reserves the right to change its distribution policy and the basis for establishing the rate of its monthly distributions at any time and may do so without prior notice to Common Shareholders.

Custodian and Transfer Agent

State Street Bank and Trust Company serves as the Fund’s custodian, and Computershare Inc. and Computershare Trust Company, N.A. serves as the Fund’s transfer agent for the Common Shares. The corresponding agent for any Preferred Shares will be identified in the related prospectus supplement. See “Custodian and Transfer Agent.”

Risk Factors

Investment in the Fund involves risk. The Fund is designed as a long-term investment and not as a trading vehicle. The Fund is not intended to be a complete investment program. Please refer to the section of the Fund’s most recent annual report on Form N-CSR entitled “Shareholder Update—Current Investment Objectives, Investment Policies and Principal Risks of the Fund—Principal Risks of the Fund,” as such principal risks may be supplemented from time to time, which is incorporated by reference herein, for a discussion of the principal risks you should consider before making an investment in the Fund. The specific risks applicable to a particular offering of Securities will be set forth in the related prospectus supplement.

Use of Proceeds

Unless otherwise specified in a prospectus supplement, the Fund will use the net proceeds from any offering of Securities, pursuant to this Prospectus, to make investments in accordance with the Fund’s investment objectives. See “Use of Proceeds.”

Federal Income Tax

The Fund has elected to be treated, and intends to qualify each year, as a regulated investment company (“RIC”) under Subchapter M of the Internal Revenue Code of 1986, as amended (the “Code”). To qualify for the favorable U.S. federal income tax treatment generally accorded to a RIC under Subchapter M of the Code the Fund must, among other requirements, derive in each taxable year at least 90% of its gross income from certain prescribed sources and satisfy a diversification test on a quarterly basis. If the Fund fails to satisfy the qualifying income or diversification requirements in any taxable year, the Fund may be eligible for relief provisions if the failures are due to reasonable cause and not willful neglect and if a penalty tax is paid with respect to each failure to satisfy the applicable requirements. Additionally, relief is provided for certain de minimis failures of the diversification requirements where the Fund corrects the failure within a specified period. In order to be eligible for the relief provisions with respect to a failure to meet the diversification requirements, the Fund may be required to dispose of certain assets. If these relief provisions were not available to the Fund and it were to fail to qualify for treatment as a RIC for a taxable year, all of its taxable income (including its net capital gain) would be subject to tax at the 21% regular corporate rate without any deduction for distributions to shareholders, and such distributions would be taxable as ordinary dividends to the extent of the Fund’s current and accumulated earnings and profits. To qualify to pay exempt-interest dividends, which are treated as items of interest excludable from gross income for federal income tax purposes, at least 50% of the value of the total assets of the Fund must consist of obligations exempt from regular income tax as of the close of each quarter of the Fund’s taxable year. If the proportion of taxable investments held by the Fund exceeds 50% of the Fund’s total assets as of the close of any quarter of any Fund taxable year, the Fund will not for that taxable year satisfy the general eligibility test that otherwise permits it to pay exempt-interest dividends. While the Fund may invest in municipal securities the interest income from which is exempt from regular federal income tax, the Fund does not expect to satisfy the requirements to pay exempt-interest dividends to shareholders.

See “Fund Tax Risk,” as contained in the section of the Fund’s most recent annual report on Form N-CSR entitled “Shareholder Update—Current Investment Objectives, Investment Policies and Principal Risks of the Fund—Principal Risks of the Fund—Fund Level and Other Risks,” and “Tax Matters.”

Governing Law

The Fund’s Declaration of Trust (the “Declaration of Trust”) is, and each Statement and Statement Supplement for Preferred Shares will be, governed by the laws of the Commonwealth of Massachusetts.

THE FUND’S INVESTMENTS

Investment Objectives and Policies

Please refer to the section of the Fund’s most recent annual report on Form N-CSR entitled “Shareholder Update—Current Investment Objectives, Investment Policies and Principal Risks of the Fund—Investment Objectives” and “—Investment Policies,” as such investment objectives and investment policies may be supplemented from time to time, which is incorporated by reference herein, for a discussion of the Fund’s investment objectives and policies.

Portfolio Composition and Other Information

Please refer to the section of the Fund’s most recent annual report on Form N-CSR entitled “Shareholder Update—Current Investment Objectives, Investment Policies and Principal Risks of the Fund—Investment Policies—Portfolio Contents,” as such portfolio contents may be supplemented from time to time, which is incorporated by reference herein, for a discussion of the investments principally included in the Fund’s portfolio. More detailed information about the Fund’s portfolio investments are contained in the SAI under “The Fund’s Investments.”

Portfolio Turnover

The Fund may engage in portfolio trading when considered appropriate, but short-term trading will not be used as the primary means of achieving the Fund’s investment objectives. For the fiscal year ended March 31, 2024, the Fund’s portfolio turnover rate was 2%. However, there are no limits on the Fund’s rate of portfolio turnover, and investments may be sold without regard to length of time held when, in Nuveen Asset Management’s opinion, investment considerations warrant such action. A higher portfolio turnover rate would result in correspondingly greater brokerage commissions and other transactional expenses that are borne by the Fund. Although these commissions and expenses are not reflected in the Fund’s “Total Annual Expenses” disclosed in this the Fund’s most recent annual report on Form N-CSR, they will be reflected in the Fund’s total return. In addition, high portfolio turnover may result in the realization of net short-term capital gains by the Fund which, when distributed to shareholders, will be taxable as ordinary income. See “Tax Matters.”

Other Policies

Certain investment policies specifically identified in the SAI as such are considered fundamental and may not be changed without shareholder approval. See “Investment Restrictions” in the SAI.

USE OF LEVERAGE

The Fund uses leverage to pursue its investment objectives. The Fund may use leverage to the extent permitted by the 1940 Act. The Fund may source leverage through a number of methods including reverse repurchase agreements (effectively a secured borrowing), investments in inverse floating rate securities of tender option bond trusts, the issuance of Preferred Shares, and borrowings (subject to certain investment restrictions). See “The Fund’s Investments—Portfolio Composition—Municipal Securities—Inverse Floating Rate Securities” and “Investment Restrictions” in the SAI. For a discussion of risks, see “Portfolio Level Risks—Inverse Floating Rate Securities Risk” and “Fund Level and Other Risks—Reverse Repurchase Agreement Risk,” as each such risk is contained in the section of the Fund’s most recent annual report on Form N-CSR entitled “Shareholder Update—Current Investment Objectives, Investment Policies and Principal Risks of the Fund—Principal Risks of the Fund.” The Fund may also use certain derivatives and other forms of leverage that have the economic effect of leverage by creating additional investment exposure.

Currently, the Fund employs leverage through its use of reverse repurchase agreements. The Fund also currently invests in residual interest certificates of tender option bond trusts, also called inverse floating rate securities, that have the economic effect of leverage because the Fund’s investment exposure to the underlying bonds held by the trust have been effectively financed by the trust’s issuance of floating rate certificates. As of May 31, 2024, the Fund’s leverage through reverse repurchase agreements and through investments in inverse floating rate securities was approximately 41% of its Managed Assets.

To date, the Fund has not issued Preferred Shares. The Fund may in the future issue certain types of Preferred Shares to increase the Fund’s leverage.

The Fund may reduce or increase leverage based upon changes in market conditions and anticipates that its leverage ratio will vary from time to time based upon variations in the value of the Fund’s holdings. So long as the net rate of income received on the Fund’s investments purchased with leverage proceeds exceeds the then current expense on any leverage, the investment of leverage proceeds will generate more net income than if the Fund had not used leverage. If so, the excess net income will be available to pay higher distributions to Common Shareholders. However, if the rate of net income received from the Fund’s portfolio investments purchased with leverage is less than the then current expense on outstanding leverage, the Fund may be required to utilize other Fund assets to make expense payments on outstanding leverage, which may result in a decline in Common Share NAV and reduced net investment income available for distribution to Common Shareholders. See “Leverage Risk,” as such risk is contained in the section of the Fund’s most recent annual report on Form N-CSR entitled “Shareholder Update—Current Investment Objectives, Investment Policies and Principal Risks of the Fund—Principal Risks of the Fund—Fund Level and Other Risks.”

Following an offering of additional Common Shares from time to time, the Fund’s leverage ratio will decrease as a result of the increase in net assets attributable to Common Shares. The Fund’s leverage ratio may decline further to the extent that the net proceeds of an offering of Common Shares are used to reduce the Fund’s leverage. A lower leverage ratio may result in lower (higher) returns to Common Shareholders over a period of time to the extent that net returns on the Fund’s investment portfolio exceed (fall below) its cost of leverage over that period, which lower (higher) returns may impact the level of the Fund’s distributions. See “Leverage Risk,” as such risk is contained in the section of the Fund’s most recent annual report on Form N-CSR entitled “Shareholder Update—Current Investment Objectives, Investment Policies and Principal Risks of the Fund—Principal Risks of the Fund—Fund Level and Other Risks.”

The Fund may use derivatives, such as interest rate swaps with varying terms, in order to manage the interest rate expense associated with all or a portion of its leverage. Interest rate swaps are bi-lateral agreements whereby parties agree to exchange future payments, typically based upon the differential of a fixed rate and a variable rate, on a specified notional amount. Interest rate swaps can enable the Fund to effectively convert its variable leverage expense to fixed, or vice versa. For example, if the Fund issues leverage having a short-term floating rate of interest, the Fund could use interest rate swaps to hedge against a rise in the short-term benchmark interest rates associated with its outstanding leverage. In doing so, the Fund would seek to achieve lower leverage costs, and thereby enhance Common Share distributions, over an extended period, which would be the result if short-term interest rates on average exceed the fixed interest rate over the term of the swap. To the extent the fixed swap rate is greater than short-term market interest rates on average over the period, overall costs associated with leverage will increase (and thereby reduce distributions to Common Shareholders) than if the Fund had not entered into the interest rate swap(s).

The Fund pays a management fee to Nuveen Fund Advisors (which in turn pays a portion of such fee to Nuveen Asset Management) based on a percentage of Managed Assets. Managed Assets include the proceeds realized and managed from the Fund’s use of most types of leverage (excluding the leverage exposure attributable to the use of futures, swaps and similar derivatives). Because Managed Assets include the Fund’s net assets as well as assets that are attributable to the Fund’s investment of the proceeds of its leverage (including instruments like inverse floating rate securities and reverse repurchase agreements), it is anticipated that the Fund’s Managed Assets will be greater than its net assets. Nuveen Fund Advisors will be responsible for using leverage to pursue the Fund’s investment objectives. Nuveen Fund Advisors will base its decision regarding whether and how much leverage to use for the Fund, and the terms of that leverage, on its assessment of whether such use of leverage is in the best interests of the Fund. However, a decision to employ or increase leverage will have the effect, all other things being equal, of increasing Managed Assets, and in turn Nuveen Fund Advisors’ and Nuveen Asset Management’s management fees. Thus, Nuveen Fund Advisors may have a conflict of interest in determining whether to use or increase leverage. Nuveen Fund Advisors will seek to manage that potential conflict by using leverage only when it determines that it would be in the best interests of the Fund and its Common Shareholders, and by periodically reviewing the Fund’s performance with the Board, the Fund’s degree of overall use of leverage and the impact of the use of leverage on that performance.

The 1940 Act generally defines a “senior security” as any bond, debenture, note, or similar obligation or instrument constituting a security and evidencing indebtedness, and any stock of a class having priority over any other class as to distribution of assets or payment of dividends; however, the term does not include any promissory note or other evidence of indebtedness issued in consideration of any loan, extension, or renewal thereof, made for temporary purposes and in an amount not exceeding five percent of the value of the Fund’s total assets. A loan shall be presumed to be for temporary purposes if it is repaid within 60 days and is not extended or renewed.

Under the 1940 Act, the Fund is not permitted to issue “senior securities representing indebtedness” if, immediately after the issuance of such senior securities representing indebtedness, the asset coverage ratio with respect to such senior securities would be less than 300%. “Senior securities representing indebtedness” include borrowings (including loans from financial institutions); debt securities; and other derivative investments or transactions such as reverse repurchase agreements and investments in inverse floating rate securities to the extent the Fund has not fully covered, segregated or earmarked cash or liquid assets having a market value at least equal to its future obligation under such instruments. With respect to any such senior securities representing indebtedness, asset coverage means the ratio which the value of the total assets of the Fund, less all liabilities and indebtedness not represented by senior securities (as defined in the 1940 Act), bears to the aggregate amount of such borrowing represented by senior securities representing indebtedness issued by the Fund.

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 with respect to such Preferred Shares would be less than 200%. With respect to any such Preferred Shares, asset coverage means the ratio which the value of the total assets of the Fund, less all liabilities and indebtedness not represented by senior securities, bears to the aggregate amount of senior securities representing indebtedness of the Fund plus the aggregate liquidation preference of such Preferred Shares.

The Fund is limited by certain investment restrictions and may only issue senior securities that are Preferred Shares except the Fund may borrow money from a bank for temporary or emergency purposes or for repurchase of its shares only in an amount not exceeding one-third of the Fund’s total assets (including the amount borrowed) less the Fund’s liabilities (other than borrowings). See “Investment Restrictions” in the SAI. These restrictions are fundamental and may not be changed without the approval of Common Shares and Preferred Shares voting together as a single class.

If the asset coverage with respect to any senior securities issued by the Fund declines below the required ratios discussed above (as a result of market fluctuations or otherwise), the Fund may sell portfolio securities when it may be disadvantageous to do so.

Certain types of leverage used by the Fund may result in the Fund being subject to certain covenants, asset coverage and, or other portfolio composition limits by its lenders, Preferred Share purchasers, rating agencies that may rate Preferred Shares, or reverse repurchase agreement counterparties. Such limitations may be more stringent than those imposed by the 1940 Act and may affect whether the Fund is able to maintain its desired amount of leverage. At this time, Nuveen Fund Advisors does not believe that any such potential investment limitations will impede it from managing the Fund’s portfolio in accordance with its investment objectives and policies.

Any borrowings of the Fund, including pursuant to reverse repurchase agreements, will have seniority over Common Shares and Preferred Shares, and any Preferred Shares will have seniority over Common Shares.

Obligations under reverse repurchase agreements are fully secured by eligible portfolio securities of the Fund. In reverse repurchase agreements, the Fund retains the risk of loss associated with the sold security. Reverse repurchase agreements also involve the risk that the purchaser fails to return the securities as agreed upon, files for bankruptcy or becomes insolvent. Upon a bankruptcy or insolvency of a counterparty, the Fund is considered to be an unsecured creditor with respect to excess collateral and as such the return of excess collateral may be delayed.

So long as any Preferred Shares are outstanding, the Fund will not be permitted to declare a dividend or distribution to Common Shareholders (other than a dividend in Common Shares of the Fund) or purchase outstanding Common Shares unless all accumulated dividends on Preferred Shares have been paid and unless the asset coverage, as defined in the 1940 Act, with respect to its Preferred Shares at the time of the declaration of such dividend or distribution or at the time of such purchase would be at least 200% after giving effect to the dividend or distribution or purchase price.

Utilization of leverage is a speculative investment technique and involves certain risks to the Common Shareholders, including increased variability of the Fund’s net income, distributions and NAV in relation to market changes. See “Leverage Risk,” as such risk is contained in the section of the Fund’s most recent annual report on Form N-CSR entitled “Shareholder Update—Current Investment Objectives, Investment Policies and Principal Risks of the Fund—Principal Risks of the Fund—Fund Level and Other Risks.” There is no assurance that the Fund will use leverage or that the Fund’s use of leverage will work as planned or achieve its goals.

Investment Management and Sub-Advisory Agreements

Investment Management Agreement. Pursuant to an investment management agreement between Nuveen Fund Advisors and the Fund (the “Investment Management Agreement”), the Fund has agreed to pay an annual management fee for the services and facilities provided by Nuveen Fund Advisors, payable on a monthly basis, based on the sum of a fund-level fee and a complex-level fee, as described below.

Fund-Level Fee. The annual fund-level fee for the Fund, payable monthly, is calculated according to the following schedule:

Average Daily Managed Assets*	Fund-Level Fee Rate
For the first $125 million		0.4500	%
For the next $125 million		0.4375	%
For the next $250 million		0.4250	%
For the next $500 million		0.4125	%
For the next $1 billion		0.4000	%
For the next $3 billion		0.3750	%
For managed assets over $5 billion		0.3625	%

Complex-Level Fee. The overall complex-level fee, payable monthly, begins at a maximum rate of 0.1600% of the Fund’s average daily managed assets, with breakpoints for eligible complex-level assets above $124.3 billion. Therefore, the maximum management fee rate for the Fund is the Fund-level fee plus 0.1600%. The current overall complex-level fee schedule is as follows:

Complex-Level Eligible Asset Breakpoint Level*	Effective Complex-Level Fee Rate at Breakpoint Level
For the first $124.3 billion		0.1600	%
For the next $75.7 billion		0.1350	%
For the next $200 billion		0.1325	%
For eligible assets over $400 billion		0.1300	%

^*	See “Investment Adviser, Sub-Adviser and Portfolio Managers” in the SAI for more detailed information about the complex-level fee and eligible complex-level assets. As of June 30, 2024, the complex-level fee rate for the Fund was 0.1574%.

In addition to the fee of Nuveen Fund Advisors, the Fund pays all other costs and expenses of its operations, including compensation of its trustees (other than those affiliated with Nuveen Fund Advisors and Nuveen Asset Management), custodian, transfer agency and dividend disbursing expenses, legal fees, expenses of independent auditors, expenses of repurchasing shares, expenses associated with any borrowings, expenses of issuing any Preferred Shares, expenses of preparing, printing and distributing shareholder reports, notices, proxy statements and reports to governmental agencies, and taxes, if any. All fees and expenses are accrued daily and deducted before payment of dividends to investors.

A discussion regarding the basis for the Board’s most recent approval of the Investment Management Agreement for the Fund may be found in the Fund’s semi-annual report to shareholders dated September 30 of each year.

Sub-Advisory Agreement. Pursuant to the Sub-Advisory Agreement, Nuveen Asset Management receives from Nuveen Fund Advisors a management fee equal to 53.8462% of Nuveen Fund Advisors’ net management fee from the Fund. Nuveen Fund Advisors and Nuveen Asset Management retain the right to reallocate investment advisory responsibilities and fees between themselves in the future.

A discussion regarding the basis for the Board’s most recent approval of the Sub-Advisory Agreement may be found in the Fund’s semi-annual report to shareholders dated September 30 of each year.

NET ASSET VALUE

The Fund’s NAV per Common Share is determined as of the close of trading (normally 4:00 p.m. Eastern time) on each day the NYSE is open for business. NAV is calculated by taking the market value of the Fund’s total assets, less all liabilities, and dividing by the total number of Common Shares outstanding. The result, rounded to the nearest cent, is the NAV per share.

The Fund utilizes independent pricing services approved by the Board to value portfolio instruments at their market value. Independent pricing services typically value non-equity portfolio instruments 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 valuing municipal securities, the pricing services may also consider, among other factors, the yields or prices of municipal securities of comparable quality, type of issue, coupon, maturity and rating and the obligor’s credit characteristics considered relevant by the pricing service or Nuveen Fund Advisors. In pricing certain securities, particularly less liquid and lower quality securities, the pricing services may consider information about a security, its issuer or market activity provided by Nuveen Fund Advisors or Nuveen Asset Management.

If a price cannot be obtained from a pricing service or other pre-approved source, or if the Fund’s valuation designee deems such price to be unreliable, or if a significant event occurs after the close of the local market but prior to the time at which the Fund’s NAV is calculated, a portfolio instrument will be valued at its fair value as determined in good faith by the Fund’s valuation designee. The Fund’s valuation designee may determine that a price is unreliable in various circumstances. For example, a price may be deemed unreliable if it has not changed for an identified period of time, or has changed from the previous day’s price by more than a threshold amount, and recent transactions and/or broker dealer price quotations differ materially from the price in question.

The Board has designated Nuveen Fund Advisors as the Fund’s valuation designee pursuant to Rule 2a-5 under the 1940 Act and delegated to Nuveen Fund Advisors the day-to-day responsibility of making fair value determinations. All fair value determinations made by Nuveen Fund Advisors are subject to review by the Board. As a general principle, the fair value of a portfolio instrument is the amount that an owner might reasonably expect to receive upon the instrument’s current sale. A range of factors and analysis may be considered when determining fair value, including relevant market data, interest rates, credit considerations and/or issuer specific news. However, fair valuation involves subjective judgments, and it is possible that the fair value determined for a portfolio instrument may be materially different from the value that could be realized upon the sale of that instrument.

DISTRIBUTIONS

To the extent that a distribution includes a return of capital the NAV per share may erode. A return of capital may occur, for example, when some or all of the money that you invested in the Fund is paid back to you. A return of capital distribution does not necessarily reflect the Fund’s investment performance and should not be confused with “yield” or “income.”

If the Fund’s distribution includes anything other than net investment income, the Fund will provide a notice to Common Shareholders of its best estimate of the distribution sources at the time of the distribution. These estimates may not match the final tax characterization (for the full year’s distributions) contained in the Common Shareholders’ 1099-DIV forms after the end of the year.

While the Fund intends to distribute all realized capital gains at least annually, the Fund may elect to retain all or a portion of any net capital gain (which is the excess of net long-term capital gain over net short-term capital loss) otherwise allocable to Common Shareholders and pay U.S. federal income tax on the retained gain. As provided under U.S. federal income tax law, Common Shareholders of record as of the end of the Fund’s taxable year will include their share of the retained net capital gain in their income for the year as a long-term capital gain (regardless of their holding period in the common shares), and will be entitled to an income tax credit or refund for the federal income tax deemed paid on their behalf by the Fund. If the Fund’s total distributions during a given year is an amount that exceeds the Fund’s current and accumulated earnings and profits, the excess would be treated by Common Shareholders as return of capital for federal income tax purposes to the extent of the Common Shareholder’s basis in their shares and thereafter as capital gain.

Distributions will be reinvested in additional shares under the Fund’s Dividend Reinvestment Plan unless a shareholder elects to receive cash. The Fund reserves the right to change its distribution policy and the basis for establishing the rate of its monthly distributions at any time and may do so without prior notice to Common Shareholders.

DIVIDEND REINVESTMENT PLAN

Please refer to the section of the Fund’s most recent annual report on Form N-CSR entitled “Shareholder Update—Dividend Reinvestment Plan,” which is incorporated by reference herein, for a discussion of the Fund’s dividend reinvestment plan.

PLAN OF DISTRIBUTION

The Fund may offer and sell Securities from time to time on an immediate, continuous or delayed basis, in one or more offerings under this Prospectus and a related prospectus supplement, on terms to be determined at the time of the offering. The Fund may offer and sell such Securities directly to one or more purchasers, to or through underwriters, through dealers or agents that the Fund designates from time to time, or through a combination of these methods. Sales of Securities may be made in transactions that are deemed to be “at the market” as defined in Rule 415 under the Securities Act of 1933, as amended (the “1933 Act”), including sales made directly on the NYSE or sales made to or through a market maker other than on an exchange.

The prospectus supplement relating to any offering of Securities will describe the terms of such offering, including, as applicable:

●

the names of any agents, underwriters or dealers;

●

any sales loads, underwriting discounts and commissions or agency fees and other items constituting underwriters’ or agents’ compensation;

●

any discounts, commissions, fees or concessions allowed or reallowed or paid to dealers or agents;

●

the public offering or purchase price of the offered Securities, the estimated net proceeds the Fund will receive from the sale and the use of proceeds; and

●

any securities exchange on which the offered Securities may be listed.

The prospectus supplement relating to any Rights offering will set forth the number of Common Shares issuable upon the exercise of each Right (or number of Rights) and the other terms of such Rights offering.

Direct Sales

The Fund may offer and sell Securities directly to, and solicit offers from, institutional investors or others who may be deemed to be underwriters as defined in the 1933 Act for any resales of Securities. In this case, no underwriters or agents would be involved. The Fund may use electronic media, including the Internet, to sell offered Securities directly. The Fund will describe the terms of any of those sales in a prospectus supplement.

By Agents

The Fund may offer and sell Securities through an agent or agents designated by the Fund from time to time. An agent may sell Securities it has purchased from the Fund as principal to other dealers for resale to investors and other purchasers, and may reallow all or any portion of the discount received in connection with the purchase from the Fund to the dealers. After the initial offering of Securities, the offering price (in the case of Securities to be resold at a fixed offering price), the concession and the discount may be changed.

By Underwriters

If any underwriters are involved in the offer and sale of Securities, such Securities will be acquired by the underwriters and may be resold by them, either at a fixed public offering price established at the time of offering or from time to time in one or more negotiated transactions or otherwise, at prices related to prevailing market prices determined at the time of sale. Unless otherwise set forth in the applicable prospectus supplement, the obligations of the underwriters to purchase Securities will be subject to conditions precedent and the underwriters will be obligated to purchase all Securities described in the prospectus supplement if any are purchased. Any initial public offering price and any discounts or concessions allowed or re-allowed or paid to underwriters may be changed from time to time.

In connection with an offering of Common Shares, if a prospectus supplement so indicates, the Fund may grant the underwriters an option to purchase additional Common Shares at the public offering price, less the underwriting discounts and commissions, within 45 days from the date of the prospectus supplement, to cover any overallotments.

By Dealers

The Fund may offer and sell Securities from time to time through one or more dealers who would purchase the securities as principal. The dealers then may resell the offered Securities to the public at fixed or varying prices to be determined by those dealers at the time of resale. The Fund will set forth the names of the dealers and the terms of the transaction in the prospectus supplement.

General

Any underwriters, dealer or agent participating in an offering of Securities may be deemed to be an “underwriter,” as that term is defined in the 1933 Act, of Securities so offered and sold, and any discounts and commission received by them, and any profit realized by them on resale of the offered Securities for whom they act as agent, may be deemed to be underwriting discounts and commissions under the 1933 Act.

Underwriters, dealers and agents may be entitled, under agreements entered into with the Fund, to indemnification by the Fund against some liabilities, including liabilities under the 1933 Act.

The Fund may offer to sell Securities either at a fixed price or at prices that may vary, at market prices prevailing at the time of sale, at prices related to prevailing market prices or at negotiated prices.

To facilitate an offering of Common Shares in an underwritten transaction and in accordance with industry practice, the underwriters may engage in transactions that stabilize, maintain, or otherwise affect the market price of the Common Shares or any other Security. Those transactions may include overallotment, entering stabilizing bids, effecting syndicate covering transactions, and reclaiming selling concessions allowed to an underwriter or a dealer.

●

An overallotment in connection with an offering creates a short position in the Common Shares for the underwriter’s own account.

●

An underwriter may place a stabilizing bid to purchase the Common Shares for the purpose of pegging, fixing, or maintaining the price of the Common Shares.

●

Underwriters may engage in syndicate covering transactions to cover overallotments or to stabilize the price of the Common Shares by bidding for, and purchasing, the Common Shares or any other Securities in the open market in order to reduce a short position created in connection with the offering.

●

The managing underwriter may impose a penalty bid on a syndicate member to reclaim a selling concession in connection with an offering when the Common Shares originally sold by the syndicate member are purchased in syndicate covering transactions or otherwise.

Any of these activities may stabilize or maintain the market price of the Securities above independent market levels. Underwriters are not required to engage in these activities and may end any of these activities at any time.

In connection with any Rights offering, the Fund may also enter into a standby underwriting arrangement with one or more underwriters pursuant to which the underwriter(s) will purchase Common Shares remaining unsubscribed for after the Rights offering.

Unless otherwise indicated in the prospectus supplement, each series of offered Preferred Shares will be a new issue of securities for which there currently is no market. Any underwriters to whom Preferred Shares are sold for public offering and sale may make a market in such Preferred Shares as permitted by applicable laws and regulations, but such underwriters will not be obligated to do so, and any such market making may be discontinued at any time without notice. Accordingly, there can be no assurance as to the development or liquidity of any market for the Preferred Shares.

Underwriters, agents and dealers may engage in transactions with or perform services, including various investment banking and other services, for the Fund and/or any of the Fund’s affiliates in the ordinary course of business.

The maximum amount of compensation to be received by any Financial Industry Regulatory Authority (“FINRA”) member or independent broker-dealer will not exceed the applicable FINRA limit for the sale of any securities being offered pursuant to Rule 415 under the Securities Act. We will not pay any compensation to any underwriter or agent in the form of warrants, options, consulting or structuring fees or similar arrangements.

To the extent permitted under the 1940 Act and the rules and regulations promulgated thereunder, the underwriters may from time to time act as a broker or dealer and receive fees in connection with the execution of the Fund’s portfolio transactions after the underwriters have ceased to be underwriters and, subject to certain restrictions, each may act as a broker while it is an underwriter.

A prospectus and accompanying prospectus supplement in electronic form may be made available on the websites maintained by underwriters. The underwriters may agree to allocate a number of Securities for sale to their online brokerage account holders. Such allocations of Securities for Internet distributions will be made on the same basis as other allocations. In addition, Securities may be sold by the underwriters to securities dealers who resell Securities to online brokerage account holders.

DESCRIPTION OF SHARES

Common Shares

The Declaration of Trust authorizes the issuance of an unlimited number of Common Shares. The Common Shares have a par value of $0.01 per share and, subject to the rights of holders of any Preferred Shares, have equal rights to the payment of dividends and the distribution of assets upon liquidation. The Common Shares when issued, are fully paid and, subject to matters discussed in “Certain Provisions in the Declaration of Trust and By-Laws,” non-assessable, and have no preemptive or conversion rights or rights to cumulative voting. A copy of the Declaration of Trust is filed with the SEC as an exhibit to the Fund’s registration statement of which this Prospectus is a part.

Each whole Common Share has one vote with respect to matters upon which a shareholder vote is required, and each fractional share shall be entitled to a proportional fractional vote consistent with the requirements of the 1940 Act and the rules promulgated thereunder, and will vote together as a single class. 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. See “—Preferred Shares” below.

The Common Shares are listed on the NYSE and trade under the ticker symbol “NBB.” The Fund intends to hold annual meetings of shareholders so long as the Common Shares are listed on a national securities exchange and such meetings are required as a condition to such listing. The Fund will not issue share certificates.

Unlike open-end funds, closed-end funds like the Fund do not provide daily redemptions. Rather, if a shareholder determines to buy additional Common Shares or sell shares already held, the shareholder may conveniently do so by trading on the exchange through a broker or otherwise. Common shares of closed-end investment companies may frequently trade on an exchange at prices lower than NAV. Common shares of closed-end investment companies like the Fund have during some periods traded at prices higher than NAV and have during other periods traded at prices lower than NAV.

Because the market value of the Common Shares may be influenced by such factors as distribution levels (which are in turn affected by expenses), call protection, dividend stability, portfolio credit quality, NAV, relative demand for and supply of such shares in the market, general market and economic conditions, and other factors beyond the control of the Fund, the Fund cannot assure you that Common Shares will trade at a price equal to or higher than NAV in the future. The Common Shares are designed primarily for long-term investors, and investors in the Common Shares should not view the Fund as a vehicle for trading purposes. See “Repurchase of Fund Shares; Conversion to Open-End Fund.”

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, by action of the Board without the approval of the Common Shareholders. The Fund currently has no Preferred Shares outstanding. In connection with the issuance of Preferred Shares pursuant to this offering, copies of the Declaration of Trust, and the applicable statement establishing and fixing the rights and preferences of Preferred Shares of the applicable series issued pursuant to this offering and the related supplement, will be filed with the SEC as exhibits to the registration statement.

Ranking and Priority of Payment

Each Preferred Share will rank on parity with each other and other Preferred Shares with respect to the payment of dividends and the distribution of assets upon liquidation. Each Preferred Share will rank senior in priority to the Common Shares as to the payment of dividends and as to the distribution of assets upon dissolution, liquidation or winding up of the affairs of the Fund.

Dividends and Distributions

The holders of Preferred Shares of each series will be entitled to receive, when, as and if declared by the Board, out of funds legally available therefor in accordance with the Declaration of Trust and applicable law, cumulative cash dividends at the dividend rate for the Preferred Shares of such series payable on the dividend payment dates with respect to the Preferred Shares of such series. Holders of Preferred Shares will not be entitled to any dividend, whether payable in cash, property or shares, in excess of full cumulative dividends on the Preferred Shares. No interest, or sum of money in lieu of interest, shall be payable in respect of any dividend payment or payments on Preferred Shares which may be in arrears, and no additional sum of money will be payable in respect of such arrearage.

Voting Rights

Preferred Shares are required to be voting shares and to have equal voting rights with Common Shares. Except as otherwise indicated in this Prospectus, the applicable prospectus supplement or the SAI and except as otherwise required by applicable law, Preferred Shares would vote together with the Common Shareholders as a single class.

Holders of Preferred Shares, voting as a separate class, will be entitled to elect two of the Fund’s trustees. The remaining trustees will be elected by the Common Shareholders and the holders of Preferred Shares, voting together as a single class. In the unlikely event that two full years of accumulated dividends are unpaid on the Preferred Shares, the holders of all outstanding Preferred Shares, voting as a separate class, will 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. In order for the Fund to take certain actions or enter into certain transactions, a separate class vote of holders of Preferred Shares would be required, in addition to the single class vote of the holders of Preferred Shares and Common Shares. See “Certain Provisions in the Declaration of Trust and By-Laws.”

Redemption, Purchase and Sale of Preferred Shares

The terms of the Preferred Shares of any series may provide that they may be subject to optional or mandatory redemption by the Fund at certain times or under certain circumstances, in whole or in part, at the liquidation preference per share plus accumulated dividends. The terms for optional redemption of Preferred Shares may provide for the payment of a redemption premium, which will be described in the applicable prospectus supplement. Any redemption or purchase of Preferred Shares by the Fund will reduce the leverage applicable to Common Shares, while any issuance of Preferred Shares by the Fund would increase such leverage.

RIGHTS OFFERINGS

The Fund may in the future, and at its discretion, choose to make offerings of Rights to its shareholders to purchase Common Shares. Rights may be issued independently or together with any other offered security and may or may not be transferable by the person purchasing or receiving the rights. In connection with a Rights offering to shareholders, the Fund would distribute certificates or other documentation evidencing the Rights and a prospectus supplement to the Fund’s shareholders as of the record date that the Fund sets for determining the shareholders eligible to receive Rights in such Rights offering. Any such future Rights offering will be made in accordance with the 1940 Act and, to the extent such Rights are transferable, will comply with applicable interpretations of the SEC or its staff, as such interpretations may be modified in the future, which currently require that: (i) the Fund’s Board make a good faith determination that such offering would result in a net benefit to existing shareholders; (ii) the offering fully protects shareholders’ preemptive rights and does not discriminate among shareholders (except for the possible effect of not offering fractional rights); (iii) management uses its best efforts to ensure an adequate trading market in the Rights for use by shareholders who do not exercise such Rights; and (iv) the ratio of such transferable Rights offering does not exceed one new share for each three rights held.

The applicable prospectus supplement would describe the following terms of the Rights (to the extent each is applicable) in respect of which this Prospectus is being delivered:

●

the period of time the offering would remain open;

●

the underwriter or distributor, if any, of the Rights and any associated underwriting fees or discounts applicable to purchases of the Rights;

●

the title of such Rights;

●

the exercise price for such Rights (or method of calculation thereof);

●

the number of such Rights issued in respect of each share;

●

the number of Rights required to purchase a single share

●

the extent to which such Rights are transferable and the market on which they may be traded if they are transferable;

●

if such Rights are transferable, a discussion regarding the Board’s basis for determining that such offering would result in a net benefit to existing shareholders;

●

if applicable, a discussion of the material U.S. federal income tax considerations applicable to the issuance or exercise of such Rights;

●

the date on which the right to exercise such Rights will commence, and the date on which such right will expire (subject to any extension);

●

the extent to which such Rights include an over-subscription privilege with respect to unsubscribed securities and the terms of such over-subscription privilege;

●

termination rights the Fund may have in connection with such Rights offering;

●

the expected trading market, if any, for such Rights; and

●

any other terms of such Rights, including exercise, settlement and other procedures and limitations relating to the transfer and exercise of such Rights.

A certain number of Rights would entitle the holder of the Right(s) to purchase for cash such number of shares at such exercise price as in each case is set forth in, or be determinable as set forth in, the prospectus supplement relating to the Rights offered thereby. Rights would be exercisable at any time up to the close of business on the expiration date for such Rights set forth in the prospectus supplement. After the close of business on the expiration date, all unexercised Rights would become void. Upon expiration of the Rights offering and the receipt of payment and the Rights certificate or other appropriate documentation properly executed and completed and duly executed at the corporate trust office of the Rights agent, or any other office indicated in the prospectus supplement, the Common Shares purchased as a result of such exercise will be issued as soon as practicable. To the extent permissible under applicable law, the Fund may determine to offer any unsubscribed offered securities directly to persons other than shareholders, to or through agents, underwriters or dealers or through a combination of such methods, as set forth in the applicable prospectus supplement.

CERTAIN PROVISIONS IN THE DECLARATION OF TRUST AND BY-LAWS

General. The By-laws of the Fund provide that by becoming a shareholder of the Fund, each shareholder shall be deemed to have agreed to be bound by the terms of the Declaration of Trust and By-laws. However, neither the Declaration of Trust nor the By-laws purport to require the waiver of a shareholder’s rights under the federal securities laws.

Shareholder and Trustee Liability. Under Massachusetts law, shareholders could, under certain circumstances, be held personally liable for the Fund’s obligations. However, the Declaration of Trust contains an express disclaimer of shareholder liability for the Fund’s debts or obligations and requires that notice of such limited liability be given in each agreement, obligation or instrument entered into or executed by the Fund or the trustees. The Declaration of Trust further provides for indemnification out of the Fund’s assets and property for all loss and expense of any shareholder held personally liable for the Fund’s obligations. Thus, the risk of a shareholder incurring financial loss on account of shareholder liability is limited to circumstances in which the Fund would be unable to meet its obligations. The Fund believes that the likelihood of such circumstances is remote.

The Declaration of Trust provides that the Fund’s obligations are not binding upon the Fund’s trustees individually, but only upon the Fund’s assets and property, and that the trustees shall not be liable for errors of judgment or mistakes of fact or law. Nothing in the Declaration of Trust, however, protects a trustee against any liability to which the trustee would otherwise be subject by reason of willful misfeasance, bad faith, gross negligence or reckless disregard of the duties involved in the conduct of the trustee’s office.

Anti-Takeover Provisions. The Declaration of Trust and By-laws include provisions that could limit the ability of other entities or persons to acquire control of the Fund or to convert the Fund to open-end status. The By-laws require the Board be divided into three classes with staggered terms. See “Management of the Fund” in the SAI. This provision of the By-laws could delay for up to two years the replacement of a majority of the Board. If Preferred Shares are issued, holders of Preferred Shares, voting as a separate class, will be entitled to elect two of the Fund’s trustees. In addition, the Declaration of Trust requires a vote by holders of at least two-thirds of the Common Shares and, if issued, Preferred Shares, voting together as a single class, except as described below, to authorize (1) a conversion of the Fund from a closed-end to an open-end investment company, (2) a merger or consolidation of the Fund, or a series or class of the Fund, with any corporation, association, trust or other organization or a reorganization of the Fund, or a series or class of the Fund, (3) a sale, lease or transfer of all or substantially all of the Fund’s assets (other than in the regular course of the Fund’s investment activities), (4) in certain circumstances, a termination of the Fund, or a series or class of the Fund or (5) a removal of trustees by shareholders, and then only for cause, unless, with respect to (1) through (4), such transaction has already been authorized by the affirmative vote of two-thirds of the total number of trustees fixed in accordance with the Declaration of Trust or the By-laws, in which case the affirmative vote of the holders of at least a majority of the Fund’s Common Shares and, if issued, Preferred Shares outstanding at the time, voting together as a single class, would be required; provided, however, that where only a particular class or series is affected (or, in the case of removing a trustee, when the trustee has been elected by only one class), only the required vote by the applicable class or series will be required. However, approval of shareholders would not be required for any transaction, whether deemed a merger, consolidation, reorganization or otherwise whereby the Fund issues shares in connection with the acquisition of assets (including those subject to liabilities) from any other investment company or similar entity. In the case of the conversion of the Fund to an open-end investment company, or in the case of any of the foregoing transactions constituting a plan of reorganization that adversely affects the holders of any outstanding Preferred Shares, the action in question also would require the affirmative vote of the holders of at least two-thirds of the Preferred Shares outstanding at the time, voting as a separate class, unless such transaction has already been authorized by the affirmative vote of two-thirds of the total number of trustees fixed in accordance with the Declaration of Trust or the By-laws, in which case the affirmative vote of the holders of at least a majority of the Fund’s Preferred Shares outstanding at the time would be required. None of the foregoing provisions may be amended except by the vote of at least two-thirds of the Common Shares and any preferred shares voting together as a single class. The votes required to approve the conversion of the Fund from a closed-end to an open-end investment company or to approve transactions constituting a plan of reorganization which adversely affects the holders of preferred shares are higher than those required by the 1940 Act. The Board believes that the provisions of the Declaration of Trust relating to such higher votes are in the best interest of the Fund and its shareholders.

Procedural Requirements on Derivative Actions, Exclusive Jurisdiction and Jury Trial Waiver. The By-laws of the Fund contain certain provisions affecting potential shareholder claims against the Fund, including procedural requirements for derivative actions, an exclusive forum provision, and the waiver of shareholder rights to a jury trial. Massachusetts is considered a “universal demand” state, meaning that under Massachusetts corporate law a shareholder must make a demand on the company before bringing a derivative action (i.e., a lawsuit brought by a shareholder on behalf of the company). The By-laws of the Fund provide detailed procedures for the bringing of derivative actions by shareholders which are modeled on the substantive provisions of the Massachusetts corporate law derivative demand statute. The procedures are intended to permit legitimate inquiries and claims while avoiding the time, expense, distraction, and other harm that can be caused to the Fund or its shareholders as a result of spurious shareholder demands and derivative actions. Among other things, these procedures:

●

provide that before bringing a derivative action, a shareholder must make a written demand to the Fund;

●

establish a 90-day review period, subject to extension in certain circumstances, for the Board of Trustees to evaluate the shareholder’s demand;

●

establish a mechanism for the Board of Trustees to submit the question of whether to maintain a derivative action to a vote of shareholders;

●

provide that if the Fund does not notify the requesting shareholder of the rejection of the demand within the applicable review period, the shareholder may commence a derivative action;

●

establish bases upon which a trustee will not be considered to be not independent for purposes of evaluating a derivative demand; and

●

provide that if the trustees who are independent for purposes of considering a shareholder demand determine in good faith within the applicable review period that the maintenance of a derivative action is not in the best interest of the Fund, the shareholder shall not be permitted to maintain a derivative action unless the shareholder first sustains the burden of proof to the court that the decision of the trustees not to pursue the requested action was not a good faith exercise of their business judgment on behalf of the Fund.

These procedures may be more restrictive than procedures for bringing derivative suits applicable to other investment companies.

The By-laws also require that actions by shareholders against the Fund, except for actions under the U.S. federal securities laws, be brought only in a certain federal court in Massachusetts, or if not permitted to be brought in federal court, then in the Business Litigation Session of the Massachusetts Superior Court in Suffolk County (the “Exclusive Jurisdictions”), and that the right to jury trial be waived to the fullest extent permitted by law. Other investment companies may not be subject to similar restrictions. The designation of Exclusive Jurisdictions may make it more expensive for a shareholder to bring a suit than if the shareholder were permitted to select another jurisdiction. Also, the designation of Exclusive Jurisdictions and the waiver of jury trials limit a shareholder’s ability to litigate a claim in the jurisdiction and in a manner that may be more favorable to the shareholder. It is possible that a court may choose not to enforce these provisions of the Fund’s By-laws.

Preemptive Rights. The Declaration of Trust provides that Common Shareholders shall have no right to acquire, purchase or subscribe for any shares or investments of the Fund, other than such right, if any, as the Fund’s Board in its discretion may determine. As of the date of this Prospectus, no preemptive rights have been granted by the Board.

Reference should be made to the Declaration of Trust and By-laws on file with the SEC for the full text of these provisions.

REPURCHASE OF FUND SHARES; CONVERSION TO OPEN-END FUND

The Fund is a closed-end investment company and as such its shareholders will not have the right to cause the Fund to redeem their shares. Instead, the Common Shares will trade in the open market at a price that will be a function of several factors, including dividend levels (which are in turn affected by expenses), NAV, call protection, dividend stability, portfolio credit quality, relative demand for and supply of such shares in the market, general market and economic conditions and other factors. Because shares of closed-end investment companies may frequently trade at prices lower than NAV, the Fund’s Board has currently determined that, at least annually, it will consider action that might be taken to reduce or eliminate any material discount from NAV in respect of Common Shares, which may include the repurchase of such shares in the open market or in private transactions, the making of a tender offer for such shares at NAV, or the conversion of the Fund to an open-end investment company. The Fund cannot assure you that its Board will decide to take any of these actions, or that share repurchases or tender offers will actually reduce market discount.

If the Fund converted to an open-end investment company, it would be required to redeem all Preferred Shares then outstanding (requiring in turn that it liquidate a portion of its investment portfolio), and the Common Shares would no longer be listed on the NYSE or elsewhere and it would likely have to significantly reduce any leverage it is then employing, which may require a repositioning of its investment portfolio, which may in turn generate substantial transaction costs, which would be borne by Common Shareholders, and may adversely affect Fund performance and Fund distributions. In contrast to a closed-end investment company, shareholders of an open-end investment company may require the company to redeem their shares at any time (except in certain circumstances as authorized by the 1940 Act or the rules thereunder) at their NAV, less any redemption charge that is in effect at the time of redemption. The Fund currently expects that any such redemptions would be made in cash. The Fund may charge sales or redemption fees upon conversion to an open-end fund. In order to avoid maintaining large cash positions or liquidating favorable investments to meet redemptions, open-end investment companies typically engage in a continuous offering of their shares. Open-end investment companies are thus subject to periodic asset in-flows and out-flows that can complicate portfolio management. The Board of Trustees may at any time propose conversion of the Fund to an open-end investment company depending upon its judgment as to the advisability of such action in light of circumstances then prevailing.

Before deciding whether to take any action if the Common Shares trade below NAV, the Fund’s Board would consider all relevant factors, including the extent and duration of the discount, the liquidity of the Fund’s portfolio, the impact of any action that might be taken on the Fund or its shareholders, and market considerations. Based on these considerations, even if the Fund’s shares should trade at a discount, the Board may determine that, in the interest of the Fund and its shareholders, no action should be taken.

TAX MATTERS

The following information is meant as a general summary for U.S. Common Shareholders. Please see the SAI for additional information. Investors should rely on their own tax adviser for advice about the particular federal, state and local tax consequences to them of investing in the Fund. This summary does not discuss the tax consequences of an investment in Rights or Preferred Shares. The tax consequences of such an investment will be discussed in the relevant prospectus supplement.

The Fund has elected and intends to qualify each year to be treated as a RIC under Subchapter M of the Internal Revenue Code. In order to qualify for treatment as a RIC, the Fund must satisfy certain requirements regarding the sources of its income, the diversification of its assets and the distribution of its income. Provided that the Fund timely distributes its income it is not expected to be subject to federal income tax. Dividends paid out of the Fund’s investment company taxable income (which includes dividends the Fund receives, interest income and net short-term capital gain) will generally be taxable to shareholders as ordinary income, except as described below with respect to qualified dividend income. Net capital gain distributions (the excess of net long-term capital gain over net short-term capital loss) are generally taxable at rates applicable to long-term capital gains regardless of how long a shareholder has held its shares. Long-term capital gains for non-corporate shareholders are currently taxable at a maximum federal income tax rate of 20%. In addition, certain individuals, estates and trusts are subject to a 3.8% Medicare tax on net investment income, including net capital gains and other taxable dividends. Corporate shareholders are taxed on capital gain at the same rates as apply to ordinary income. Distributions derived from qualified dividend income and received by a non- corporate shareholder will be taxed at the rates applicable to long-term capital gain. In order for some portion of the dividends received by a shareholder to be qualified dividend income, the Fund must meet certain holding period and other requirements with respect to the dividend-paying stocks in its portfolio and the non-corporate shareholder must meet certain holding period and other requirements with respect to its shares of the Fund. Taxable distributions are taxable whether or not such distributions are reinvested in the Fund. Dividend distributions may be subject to state and local taxation, depending on a shareholder’s situation. The Fund’s investment strategies may significantly limit its ability to make distributions eligible to be reported as qualified dividend income or for the dividends-received deduction for corporate shareholders. While the Fund may invest in municipal securities the interest income from which is exempt from regular federal income tax, the Fund does not expect to satisfy the requirements to pay exempt-interest dividends to shareholders.

If the Fund’s total distributions exceed both the current taxable year’s earnings and profits and accumulated earnings and profits from prior years, the excess generally will be treated as a tax-free return of capital up to and including the amount of a shareholder’s tax basis in its shares of the Fund, and thereafter as capital gain. Upon a sale of shares of the Fund, the amount, if any, by which the sales price exceeds the basis in the shares of the Fund is gain subject to federal income tax. Because a return of capital reduces basis in the shares of the Fund, it will increase the amount of gain or decrease the amount of loss on a shareholder’s subsequent disposition of the shares of the Fund.

As a regulated investment company, the Fund will not be subject to federal income tax in any taxable year provided that it meets certain distribution requirements. The Fund may retain for investment some (or all) of its net capital gain. If the Fund retains any net capital gain or investment company taxable income, it will be subject to tax at the regular corporate rate on the amount retained. If the Fund retains any net capital gain, it may designate the retained amount as undistributed capital gains in a notice to its shareholders who if subject to federal income tax on long-term capital gains, (i) will be required to include in income for federal income tax purposes, as long-term capital gain, their share of such undistributed amount; (ii) will be entitled to credit their proportionate shares of the federal income tax paid by the Fund on such undistributed amount against their federal income tax liabilities, if any; and (iii) may claim refunds to the extent the credit exceeds such liabilities. For federal income tax purposes, the basis of shares owned by a shareholder of the Fund will be increased by an amount equal to the difference between the amount of undistributed capital gains included in the shareholder’s gross income and the tax deemed paid by the shareholder under clause (ii) of the preceding sentence.

If the Fund utilizes leverage through borrowings, or otherwise, asset coverage limitations imposed by the 1940 Act as well as additional restrictions that may be imposed by certain lenders on the payment of dividends or distributions potentially could limit or eliminate the Fund’s ability to make distributions on its common shares and/or preferred shares, if any, until the asset coverage is restored. These limitations could prevent the Fund from distributing at least 90% of its investment company taxable income as is required under the Code and therefore might jeopardize the Fund’s qualification as a regulated investment company and/or might subject the Fund to a nondeductible 4% federal excise tax. The Fund endeavors to avoid restrictions on its ability to distribute dividends.

Dividends declared by the Fund in October, November or December, payable to shareholders of record in such a month, and paid during the following January will be treated as having been received by shareholders in the year the distributions were declared.

Each shareholder will receive an annual statement summarizing the U.S. federal income tax status of all distributions.

The repurchase or sale of Common Shares normally will result in capital gain or loss to Common Shareholders who hold their shares as capital assets. Generally, a shareholder’s gain or loss will be long-term capital gain or loss if the shares have been held for more than one year even though the increase in value in such Common Shares may be at least partly attributable to tax-exempt interest income. For non-corporate taxpayers, long-term capital gains are currently taxed at rates of up to 20%. Short-term capital gains and other ordinary income are taxed to non-corporate taxpayers at ordinary income rates. If a shareholder sells or otherwise disposes of Common Shares before holding them for six months, any loss on the sale or disposition will be treated as a long-term capital loss to the extent of any amounts treated as distributions to the common shareholder of long-term capital gain (including any amount credited to the common shareholder as undistributed capital gain). Any loss realized by a shareholder on the disposition of shares held 6 months or less is disallowed to the extent of the amount of exempt-interest dividends received by the shareholder with respect to Common Shares. Any loss realized on a sale of shares of the Fund will be disallowed to the extent those shares of the Fund are replaced by substantially identical shares of the Fund (including shares acquired by reason of participation in the Plan) within a period of 61 days beginning 30 days before and ending 30 days after the date of disposition of the original shares, or to the extent the shareholder enters into a contract or option to repurchase shares within such period. In that event, the basis of the replacement shares of the Fund will be adjusted to reflect the disallowed loss.

The Fund may be required to withhold (as “backup withholding”) U.S. federal income tax for distributions (including exempt-interest dividends) and repurchase proceeds payable to a shareholder if the shareholder fails to provide the Fund with the shareholder’s correct taxpayer identification number or to make required certifications, or if the shareholder has been notified by the IRS that the shareholder is subject to backup withholding. The backup withholding rate is 24%. Backup withholding is not an additional tax; rather, it is a way in which the IRS ensures it will collect taxes otherwise due. Any amounts withheld may be credited against a shareholder’s U.S. federal income tax liability.

CUSTODIAN AND TRANSFER AGENT

The custodian of the assets of the Fund is State Street Bank and Trust Company, One Congress Street, Suite 1, Boston, Massachusetts 02114-2016 (the “Custodian”). The Custodian performs custodial, fund accounting and portfolio accounting services.

USE OF PROCEEDS

Unless otherwise specified in a prospectus supplement, the net proceeds from the issuance of Securities hereunder will be invested in accordance with the Fund’s investment objectives and policies as stated below. Pending investment, the timing of which may vary depending on the size of the investment but in no case is expected to exceed 30 days, it is anticipated that the proceeds will be invested in short-term or long-term securities issued by the U.S. Government and its agencies or instrumentalities or in high quality, short-term money market instruments.

INVESTMENT OBJECTIVES AND POLICIES

Please refer to the section of the Fund’s most recent annual report on Form N-CSR entitled “Shareholder Update—Current Investment Objectives, Investment Policies and Principal Risks of the Fund—Investment Objectives” and “—Investment Policies,” as such investment objectives and investment policies may be supplemented from time to time, which is incorporated by reference herein, for a discussion of the Fund’s investment objectives and policies.

INVESTMENT RESTRICTIONS

Below are the fundamental investment restrictions of the Fund. The Fund cannot change its fundamental investment restrictions without the approval of the holders of a “majority of the outstanding voting securities” of the Fund as is defined in the 1940 Act. When used with respect to particular shares of the Fund, a “majority of the outstanding voting securities” means the vote of (i) 67% or more of the Fund’s shares present at a meeting, if the holders of more than 50% of the Fund’s shares are present or represented by proxy; or (ii) more than 50% of the Fund’s outstanding common shares, whichever is less. Except for the fundamental policies set forth below and the Fund’s investment objectives, all of the Fund’s other investment policies are non-fundamental and can be changed by the Board of Trustees of the Fund (the “Board”) without a vote of the shareholders. However, shareholders will receive at least 60 days’ prior notice of any change to the Fund’s investment policy to invest at least 80% of its Assets in taxable municipal securities.

Except as described below, the Fund may not:

(1) Issue senior securities, as defined in the 1940 Act, except as permitted by the 1940 Act.

(2) Borrow money, except as permitted by the 1940 Act and exemptive orders granted under the 1940 Act.

(3) Act as underwriter of another issuer’s securities, except to the extent that the Fund may be deemed to be an underwriter within the meaning of the Securities Act of 1933, as amended (the “Securities Act”), in connection with the purchase and sale of portfolio securities.

(4) Invest more than 25% of its total assets in securities of issuers in any one industry, provided, however, that such limitation shall not apply to municipal securities other than those municipal securities backed only by the assets and revenues of non-governmental users.

(5) Purchase or sell real estate, but this shall not prevent the Fund from investing in municipal securities secured by real estate or interests therein or foreclosing upon and selling such real estate.

(6) Purchase or sell physical commodities unless acquired as a result of ownership of securities or other instruments (but this shall not prevent the Fund from purchasing or selling options, futures contracts or derivative instruments or from investing in securities or other instruments backed by physical commodities).

(7) Make loans, except as permitted by the 1940 Act and exemptive orders granted under the 1940 Act.

(8) With respect to 75% of the value of the Fund’s total assets, purchase any securities (other than obligations issued or guaranteed by the U.S. Government or by its agencies or instrumentalities), if as a result more than 5% of the Fund’s total assets would then be invested in securities of a single issuer or if as a result the Fund would hold more than 10% of the outstanding voting securities of any single issuer.

With respect to the limitations set forth in paragraphs 1 and 2 above, Section 18(c) of the 1940 Act generally limits a registered closed-end investment company to issuing one class of senior securities representing indebtedness and one class of senior securities representing stock, except that the class of indebtedness or stock may be issued in one or more series, and promissory notes or other evidences of indebtedness issued in consideration of any loan, extension, or renewal thereof, made by a bank or other person and privately arranged, and not intended to be publicly distributed, are not deemed a separate class of senior securities.

With respect to the limitation set forth in paragraph 2 above, Section 18(a) of the 1940 Act generally prohibits a registered closed-end fund from incurring borrowings if, immediately thereafter, the aggregate amount of its borrowings exceeds 33 1/3% of its total assets.

With respect to the limitation set forth in paragraph 4 above, governments and their political subdivisions shall not be deemed to be members of any industry.

With respect to the limitation set forth in paragraph 7 above, Section 21 of the 1940 Act makes it unlawful for a registered investment company, like the Fund, to lend money or other property if (i) the investment company’s policies set forth in its registration statement do not permit such a loan or (ii) the borrower controls or is under common control with the investment company.

With respect to the limitation set forth in paragraph 8 above, a governmental issuer shall be deemed the single issuer of a security when its assets and revenues are separate from other governmental entities and its securities are backed only by its assets and revenues. Similarly, in the case of a non-governmental issuer, if the security is backed only by the assets and revenues of the non-governmental issuer, then such non-governmental issuer would be deemed to be the single issuer. Where a security is also backed by the enforceable obligation of a superior or unrelated governmental or other entity (other than a bond insurer), it shall also be included in the computation of securities owned that are issued by such governmental or other entity. Where a security is guaranteed by a governmental entity or some other facility, such as a bank guarantee or letter of credit, such a guarantee or letter of credit would be considered a separate security and would be treated as an issue of such government, other entity or bank. When a municipal security is insured by bond insurance, it shall not be considered a security that is issued or guaranteed by the insurer; instead, the issuer of such municipal security will be determined in accordance with the principles set forth above. The foregoing restrictions do not limit the percentage of the Fund’s assets that may be invested in municipal securities insured by any given insurer.

Under the 1940 Act, subject to limited exceptions, the Fund may invest up to 10% of its total assets in the aggregate in shares of other investment companies and up to 5% of its total assets in any one investment company, provided the investment does not represent more than 3% of the voting stock of the acquired investment company at the time such shares are purchased. As a stockholder in any investment company, the Fund will bear its ratable share of that investment company’s expenses, and will remain subject to payment of the Fund’s management, advisory and administrative fees with respect to assets so invested. Shareholders would therefore be subject to duplicative expenses to the extent their Fund invests in other investment companies. In addition, the securities of other investment companies may be leveraged and therefore may be subject to the same leverage risks described herein.

In addition to the foregoing fundamental investment policies, the Fund is also subject to the following non-fundamental restrictions and policies, which may be changed by the Board without shareholder approval. The Fund may not:

(1) Sell securities short, unless the Fund owns or has the right to obtain securities equivalent in kind and amount to the securities sold at no added cost, and provided that transactions in options, futures contracts, options on futures contracts, or other derivative instruments are not deemed to constitute selling securities short.

(2) Purchase securities of open-end or closed-end investment companies except in compliance with the 1940 Act or any exemptive relief obtained thereunder.

(3) Purchase securities of companies for the purpose of exercising control, except that the Fund may invest up to 5% of its net assets in tax-exempt or taxable fixed-income securities or equity securities for the purpose of acquiring control of an issuer whose municipal securities (a) the Fund already owns and (b) have deteriorated or are expected shortly to deteriorate significantly in credit quality, provided Nuveen Asset Management determines that such investment should enable the Fund to better maximize the value of its existing investment in such issuer.

The restrictions and other limitations set forth above will apply only at the time of purchase of securities 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.

The Fund pays regular monthly cash distributions to Common Shareholders (stated in terms of a fixed cents per Common Share dividend distribution rate which may be set from time to time). The Fund’s ability to maintain its declared Common Share distribution rate will depend on a number of factors. As portfolio and market conditions change, the rate of dividends on the Common Shares and the Fund’s dividend policy could change. See “Distributions” in the Prospectus Supplement. If the Fund has any borrowings or has any other outstanding senior securities representing indebtedness, the Fund will generally not be permitted under the 1940 Act to declare dividends or other distributions on its Common Shares unless, at the time of such declaration or distribution, the asset coverage applicable to any such senior securities representing indebtedness (determined after deducting the dividend or distribution amount) is at least 300%.

The Fund may issue senior securities, including preferred shares, notes and other evidences of indebtedness (including bank borrowings or commercial paper). If it does so, the Fund may be subject to certain restrictions imposed by either guidelines of one or more NRSROs that may issue ratings for senior securities issued by the Fund or, if the Fund borrows from a lender, by the lender. These guidelines may impose asset coverage or portfolio composition requirements that are more stringent than those imposed on the Fund by the 1940 Act. In addition, reverse repurchase agreement counterparties may require certain criteria for securities included within such agreements. If these restrictions were to apply, it is not anticipated that these covenants, guidelines or security criteria would impede Nuveen Asset Management from managing the Fund’s portfolio in accordance with the Fund’s investment objectives and policies.

THE FUND’S INVESTMENTS

Municipal Securities

General. The Fund may invest in taxable municipal securities (including BABs) and tax-exempt municipal securities, including municipal bonds and notes, other securities issued to finance and refinance public projects, and other related securities and derivative instruments creating exposure to municipal bonds, notes and securities that provide for the payment of interest income that is exempt from regular U.S. federal income tax. Municipal securities are often issued by state and local governmental entities to finance or refinance public projects such as roads, schools, and water supply systems. Municipal securities may also be issued on behalf of private entities or for private activities, such as housing, medical and educational facility construction, or for privately owned transportation, electric utility or pollution control projects. Municipal securities may be issued on a long-term basis to provide permanent financing. The repayment of such debt may be secured generally by a pledge of the full faith and credit taxing power of the issuer, a limited or special tax, or any other revenue source, including project revenues, which may include tolls, fees and other user charges, lease payments and mortgage payments. Municipal securities may also be issued to finance projects on a short-term interim basis, anticipating repayment with the proceeds of the later issuance of long-term debt. The Fund may purchase municipal securities in the form of bonds, notes, leases or certificates of participation; structured as callable or non-callable; with payment forms including fixed coupon, variable rate or zero coupon, including capital appreciation bonds, floating rate securities, and inverse floating rate securities; or may be acquired through investments in pooled vehicles, partnerships or other investment companies. Inverse floating rate securities are securities that pay interest at rates that vary inversely with changes in prevailing short-term tax-exempt interest rates and represent a leveraged investment in an underlying municipal security, which could have the economic effect of leverage.

Securities of below-investment-grade quality (Ba/BB or below) are commonly referred to as “junk bonds.” Municipal securities rated below-investment-grade quality are obligations of issuers that are considered predominantly speculative with respect to the issuer’s capacity to pay interest and repay principal according to the terms of the obligation and, therefore, carry greater investment risk, including the possibility of issuer default and bankruptcy and increased market price volatility. Municipal securities rated below-investment-grade tend to be less marketable than higher-quality securities because the market for them is less broad. The market for unrated municipal securities is even narrower. During periods of thin trading in these markets, the spread between bid and asked prices is likely to increase significantly and the Fund may have greater difficulty selling its holdings of these types of portfolio securities. The Fund will be more dependent on the research and analysis of Nuveen Fund Advisors, LLC (“Nuveen Fund Advisors” or the “Adviser”), the Fund’s investment adviser, and/or Nuveen Asset Management, LLC (“Nuveen Asset Management” or the “Sub-Adviser”), the Fund’s sub-adviser, when investing in these securities.

The Fund may invest in distressed securities but may not invest in the securities of an issuer which, at the time of investment, is in default on its obligations to pay principal or interest thereon when due or that is involved in a bankruptcy proceeding (i.e., rated below C-, at the time of investment); provided, however, that Nuveen Asset Management may determine that it is in the best interest of shareholders in pursuing a workout arrangement with issuers of defaulted securities to make loans to the defaulted issuer or another party, or purchase a debt, equity or other interest from the defaulted issuer or another party, or take other related or similar steps involving the investment of additional monies, but only if that issuer's securities are already held by the Fund.

Municipal securities rated Baa or BBB are considered “investment grade” securities. Issuers of municipal securities rated BBB or Baa are regarded as having average creditworthiness relative to other U.S. municipal issuers; however, adverse economic conditions or changing circumstances are more likely to lead to a weakened capacity of the issuer to meet its financial commitments.

The credit ratings assigned by rating agencies from time to time represent their opinions as to the quality of the municipal securities they rate. However, it should be emphasized that ratings are general and are not absolute standards of quality. Consequently, municipal securities with the same maturity, coupon and rating may have different yields while obligations of the same maturity and coupon with different ratings may have the same yield. A general description of the ratings of municipal securities by S&P Global Ratings, Moody’s Investors Service, Inc. and Fitch Ratings, Inc. is set forth in Appendix A to the SAI.

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. 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 also may purchase municipal securities that represent lease obligations, municipal notes, pre-refunded municipal bonds, private activity bonds, floating rate securities and other related securities and may purchase derivative instruments that create exposure to municipal bonds, notes and securities.

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. A municipal security’s market value generally will depend upon its form, maturity, call features, and interest rate, as well as the credit quality of the issuer, all such factors examined in the context of the municipal securities market and interest rate levels and trends. 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.

BABs offered an alternative form of financing for state and local government entities whose primary means for accessing the capital markets traditionally had been through issuance of tax-exempt municipal securities. BABs are taxable municipal obligations issued pursuant to the American Recovery and Reinvestment Act of 2009. Enacted in February 2009 with the intent to assist state and local governments in financing capital projects at lower borrowing costs, the American Recovery and Reinvestment Act of 2009 authorized state and local governments to issue taxable bonds on which, assuming certain specified conditions are satisfied, issuers may either (i) receive payments from the U.S. Treasury equal to a specified percentage of their interest payments (in the case of direct pay BABs) or (ii) cause investors in the bonds to receive federal tax credits (in the case of tax credit BABs). Unlike most other municipal obligations, interest received on BABs is subject to U.S. federal income tax and may be subject to state income tax. Under the terms of the American Recovery and Reinvestment Act of 2009, issuers of direct pay BABs are entitled to receive payments from the U.S. Treasury currently equal to 35% (or 45% in the case of Recovery Zone Economic Development Bonds) of the interest paid on the bonds. Holders of tax credit BABs receive a federal tax credit currently equal to 35% of the coupon interest received. The Fund does not expect to receive (or pass through to Common Shareholders) tax credits as a result of its investments. The federal interest subsidy or tax credit continues for the life of the bonds, provided that the issuer continues to meet all applicable program eligibility requirements. Under the sequestration process under the Budget Control Act of 2011, automatic spending cuts that became effective on March 1, 2013 reduced the federal subsidy for BABs and other subsidized taxable municipal bonds. The reduced federal subsidy has been extended through 2024. The subsidy payments were reduced by 6.6% in 2018 and 6.2% in 2019. The Fund cannot predict future reductions in the federal subsidy for BABs and other subsidized taxable municipal bonds.

Pursuant to the terms of the American Recovery and Reinvestment Act of 2009, the issuance of Build America Bonds ceased on December 31, 2010. As a result, the availability of such bonds is limited and there can be no assurance that Build America Bonds will be actively traded. The market for the bonds and/or their liquidity may be negatively affected. No further issuance is permitted unless Congress were to renew the program at a future date.

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 that is issued by a state or local government to acquire equipment and facilities. Income from such obligations generally is exempt 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 purchase municipal securities representing lease obligations only where Nuveen Fund Advisors and/or 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 typically are 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 Administration 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. However, an investment in such instruments 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.

Private Activity Bonds. Private activity bonds are issued by or on behalf of public authorities to obtain funds to provide privately operated housing facilities, airport, mass transit or port facilities, sewage disposal, solid waste disposal or hazardous waste treatment or disposal facilities and certain local facilities for water supply, gas or electricity. Other types of private activity bonds, the proceeds of which are used for the construction, 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.

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, and can exceed three times for more “highly leveraged” trusts. 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 affect only 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 also may 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, generally are 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 generally are 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.

Illiquid Securities

The Fund may invest in municipal securities and other instruments that, at the time of investment, are illiquid (i.e., securities that are not readily marketable). For this purpose, illiquid securities may include, but are not limited to, restricted securities (securities the disposition of which is restricted under the federal securities laws), securities that may only be resold pursuant to Rule 144A under the Securities Act, that are deemed to be illiquid, and certain repurchase agreements. Inverse floating rate securities or the residual interest certificates of tender option bond trusts are not considered illiquid securities. The Board or its delegate has the ultimate authority to determine which securities are liquid or illiquid. The Board has delegated to Nuveen Asset Management the day-to-day determination of the illiquidity of any security held by the Fund, although it has retained oversight and ultimate responsibility for such determinations. Currently, no definitive liquidity criteria are used. Each Board has directed Nuveen Asset Management, when making liquidity determinations, to consider such factors as (i) the nature of the market for a security (including the institutional private resale market; the frequency of trades and quotes for the security; the number of dealers willing to purchase or sell the security; the amount of time normally needed to dispose of the security; and the method of soliciting offers and the mechanics of transfer), (ii) the terms of certain securities or other instruments allowing for the disposition to a third party or the issuer thereof (e.g., certain repurchase obligations and demand instruments), and (iii) other relevant factors. The assets used to cover OTC derivatives held by the Fund will be considered illiquid until the OTC derivatives are sold to qualified dealers who agree that the Fund may repurchase them at a maximum price to be calculated by a formula set forth in an agreement. The “cover” for an OTC derivative subject to this procedure would be considered illiquid only to the extent that the maximum repurchase price under the formula exceeds the intrinsic value of the derivative.

Restricted securities 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 Securities 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 a security under an effective registration statement. If, during such a period, adverse market conditions were to develop, the Fund might obtain a less favorable price than that which prevailed when it decided to sell. Illiquid securities will be priced at a fair value as determined in good faith by the Board or its delegatee. If, through the appreciation of illiquid securities or the depreciation of liquid securities, the Fund should be in a position where more than 50% of the value of its Managed Assets is invested in illiquid securities, including restricted securities that are not readily marketable, the Fund will take such steps as are deemed advisable by Nuveen Asset Management, if any, to protect liquidity.

Short-Term Investments

Short-Term Taxable Fixed Income Securities. For temporary defensive purposes or to keep cash on hand fully invested, the Fund may invest up to 100% of its Managed Assets in cash equivalents and short-term taxable fixed-income securities. Short-term taxable fixed income investments are defined to include, without limitation, the following:

(1) U.S. Government securities, including bills, notes and bonds differing as to maturity and rates of interest that are either issued or guaranteed by the U.S. Treasury or by U.S. Government agencies or instrumentalities. U.S. Government agency securities include securities issued by (a) the Federal Housing Administration, Farmers Home Administration, Export-Import Bank of the United States, Small Business Administration, and the Government National Mortgage Association, whose securities are supported by the full faith and credit of the United States; (b) the Federal Home Loan Banks, Federal Intermediate Credit Banks, and the Tennessee Valley Authority, whose securities are supported by the right of the agency to borrow from the U.S. Treasury; (c) the Federal National Mortgage Association, whose securities are supported by the discretionary authority of the U.S. Government to purchase certain obligations of the agency or instrumentality; and (d) the Student Loan Marketing Association, whose securities are supported only by its credit. While the U.S. Government provides financial support to such U.S. Government-sponsored agencies or instrumentalities, no assurance can be given that it always will do so since it is not so obligated by law. The U.S. Government, its agencies and instrumentalities do not guarantee the market value of their securities. Consequently, the value of such securities may fluctuate.

(2) Certificates of deposit issued against funds deposited in a bank or a savings and loan association. Such certificates are for a definite period of time, earn a specified rate of return, and are normally negotiable. The issuer of a certificate of deposit agrees to pay the amount deposited plus interest to the bearer of the certificate on the date specified thereon. Under current Federal Deposit Insurance Company regulations, the maximum insurance payable as to any one certificate of deposit is $250,000; therefore, certificates of deposit purchased by the Fund may not be fully insured.

(3) Repurchase agreements, which involve purchases of debt securities. At the time the Fund purchases securities pursuant to a repurchase agreement, it simultaneously agrees to resell and redeliver such securities to the seller, who also simultaneously agrees to buy back the securities at a fixed price and time. This assures a predetermined yield for the Fund during its holding period, since the resale price is always greater than the purchase price and reflects an agreed-upon market rate. Such actions afford an opportunity for the Fund to invest temporarily available cash. The Fund may enter into repurchase agreements only with respect to obligations of the U.S. Government, its agencies or instrumentalities; certificates of deposit; or bankers’ acceptances in which the Fund may invest. Repurchase agreements may be considered loans to the seller, collateralized by the underlying securities. The risk to the Fund is limited to the ability of the seller to pay the agreed-upon sum on the repurchase date; in the event of default, the repurchase agreement provides that the Fund is entitled to sell the underlying collateral. If the value of the collateral declines after the agreement is entered into, and if the seller defaults under a repurchase agreement when the value of the underlying collateral is less than the repurchase price, the Fund could incur a loss of both principal and interest. Nuveen Fund Advisors, monitors the value of the collateral at the time the action is entered into and at all times during the term of the repurchase agreement. Nuveen Fund Advisors does so in an effort to determine that the value of the collateral always equals or exceeds the agreed-upon repurchase price to be paid to the Fund. If the seller were to be subject to a federal bankruptcy proceeding, the ability of the Fund to liquidate the collateral could be delayed or impaired because of certain provisions of the bankruptcy laws.

(4) Commercial paper, which consists of short-term unsecured promissory notes, including variable rate master demand notes issued by corporations to finance their current operations. Master demand notes are direct lending arrangements between the Fund and a corporation. There is no secondary market for such notes. However, they are redeemable by the Fund at any time. Nuveen Fund Advisors will consider the financial condition of the corporation (e.g., earning power, cash flow, and other liquidity measures) and will continuously monitor the corporation’s ability to meet all of its financial obligations, because the Fund’s liquidity might be impaired if the corporation were unable to pay principal and interest on demand. Investments in commercial paper will be limited to commercial paper rated in the highest categories by a major rating agency and which mature within one year of the date of purchase or carry a variable or floating rate of interest.

(5) Taxable municipal securities, which may consist of short-term bonds or other short-term securities issued by a municipal issuer for which interest or other investment return is included in gross income for federal income tax purposes. A municipal security may be issued on a taxable basis because the intended use of proceeds does not meet federal tax law requirements for the exclusion from gross income (e.g., private activity bonds that are not qualified bonds) or because certain other federal tax law requirements are not met (e.g., insufficient volume cap).

Short-Term Tax-Exempt Fixed Income Securities. Short-term tax-exempt fixed-income securities are securities that are exempt from regular federal income tax and mature within three years or less from the date of issuance. Short-term tax-exempt fixed income securities are defined to include, without limitation, the following:

(1) Bond Anticipation Notes (“BANs”) are usually general obligations of state and local governmental issuers which are sold to obtain interim financing for projects that will eventually be funded through the sale of long-term debt obligations or bonds. The ability of an issuer to meet its obligations on its BANs is primarily dependent on the issuer’s access to the long-term municipal bond market and the likelihood that the proceeds of such bond sales will be used to pay the principal and interest on the BANs.

(2) Tax Anticipation Notes (“TANs”) are issued by state and local governments to finance the current operations of such governments. Repayment is generally to be derived from specific future tax revenues. TANs are usually general obligations of the issuer. Weakness in an issuer’s capacity to raise taxes due to, among other things, a decline in its tax base or a rise in delinquencies, could adversely affect the issuer’s ability to meet its obligations on outstanding TANs.

(3) Revenue Anticipation Notes (“RANs”) are issued by governments or governmental bodies with the expectation that future revenues from a designated source will be used to repay the notes. In general, they also constitute general obligations of the issuer. A decline in the receipt of projected revenues, such as anticipated revenues from another level of government, could adversely affect an issuer’s ability to meet its obligations on outstanding RANs. In addition, the possibility that the revenues would, when received, be used to meet other obligations could affect the ability of the issuer to pay the principal and interest on RANs.

(4) Construction loan notes are issued to provide construction financing for specific projects. Frequently, these notes are redeemed with funds obtained from the Federal Housing Administration.

(5) Bank notes are notes issued by local government bodies and agencies, such as those described above to commercial banks as evidence of borrowings. The purposes for which the notes are issued are varied but they are frequently issued to meet short-term working capital or capital project needs. These notes may have risks similar to the risks associated with TANs and RANs.

(6) Tax-exempt commercial paper (“Municipal Paper”) represents very short-term unsecured, negotiable promissory notes, issued by states, municipalities and their agencies. Payment of principal and interest on issues of municipal paper may be made from various sources to the extent the funds are available therefrom. Maturities of municipal paper generally will be shorter than the maturities of TANs, BANs or RANs. There is a limited secondary market for issues of Municipal Paper.

Certain municipal securities may carry variable or floating rates of interest whereby the rate of interest is not fixed but varies with changes in specified market rates or indices, such as a bank prime rate or a tax-exempt money market index.

While the various types of notes described above as a group represent the major portion of the short-term tax-exempt note market, other types of notes are available in the marketplace, and the Fund may invest in such other types of notes to the extent permitted under its investment objectives, policies and limitations. Such notes may be issued for different purposes and may be secured differently from those mentioned above.

When-Issued and Delayed-Delivery Transactions

The Fund may buy and sell municipal securities on a when-issued or delayed delivery basis, making payment or taking delivery at a later date, normally within 15 to 45 days of the trade date. On such transactions, the payment obligation and the interest rate are fixed at the time the buyer enters into the commitment. Income generated by any such assets which provide taxable income for federal income tax purposes is includable in the taxable income of the Fund and, to the extent distributed, will be taxable to shareholders. The Fund may enter into contracts to purchase municipal securities on a forward basis (i.e., where settlement will occur more than 60 days from the date of the transaction) only to the extent that the Fund specifically collateralizes such obligations with a security that is expected to be called or mature within 60 days before or after the settlement date of the forward transaction. The commitment to purchase securities on a when-issued, delayed delivery or forward basis may involve an element of risk because no interest accrues on the bonds prior to settlement and, at the time of delivery, the market value may be less than cost.

Derivatives and Hedging Strategies

The Fund may engage in hedging transactions, and otherwise use various types of derivative instruments, described below, to manage or reduce interest rate risk, to effectively gain particular market exposures, to seek to enhance returns, and to reduce transaction costs, among other reasons. In addition to inverse floating rate securities and structured notes, the Fund may invest in certain other derivative instruments in pursuit of its investment objectives. Such instruments include financial futures contracts, swap contracts (including interest rate and credit default swaps), options on financial futures, options on swap contracts or other derivative instruments whose prices, in the Adviser’s and/or the Sub-Adviser’s opinion, correlate with the prices of the Fund’s investments.

“Hedging” is a term used for various methods of seeking to preserve portfolio capital value by offsetting price changes in one investment through making another investment whose price should tend to move in the opposite direction.

A “derivative” is a financial contract whose value is based on (or “derived” from) a traditional security (such as a stock or a bond), an asset (such as a commodity like gold), or a market index (such as the S&P National Bond Fund Index). Some forms of derivatives may trade on exchanges, while non-standardized derivatives, which tend to be more specialized and complex, trade in “over-the-counter” (“OTC”) or a one-on-one basis. It may be desirable and possible in various market environments to partially hedge the portfolio against fluctuations in market value due to market interest rate or credit quality fluctuations, or instead to gain a desired investment exposure, by entering into various types of derivative transactions, including financial futures and index futures as well as related put and call options on such instruments, structured notes, or interest rate swaps on taxable or tax-exempt securities or indexes (which may be “forward-starting”), credit default swaps, and options on interest rate swaps, among others.

These transactions present certain risks. In particular, the imperfect correlation between price movements in the futures contract and price movements in the securities being hedged creates the possibility that losses on the hedge by the Fund may be greater than gains in the value of the securities in the Fund’s portfolio. In addition, futures and options markets may not be liquid in all circumstances. As a result, in volatile markets, the Fund may not be able to close out the transaction without incurring losses substantially greater than the initial deposit. Finally, the potential deposit requirements in futures contracts create an ongoing greater potential financial risk than do options transactions, where the exposure is limited to the cost of the initial premium. Losses due to hedging transactions will reduce yield. The Fund will not make any investment (whether an initial premium or deposit or a subsequent deposit) other than as necessary to close a prior investment if, immediately after such investment, the sum of the amount of its premiums and deposits would exceed 15% of the Fund’s Managed Assets. The Fund will invest in these instruments only in markets believed by the Adviser and/or the Sub-Adviser to be active and sufficiently liquid. Net gains, if any, from hedging and other portfolio transactions will be distributed as taxable distributions to shareholders. Successful implementation of most hedging strategies will generate taxable income.

Both parties entering into an index or financial futures contract are required to post an initial deposit, typically equal to from 1% to 5% of the total contract price. Typically, option holders enter into offsetting closing transactions to enable settlement in cash rather than take delivery of the position in the future of the underlying security. Interest rate swap and credit default swap transactions are typically entered on a net basis, meaning that the two payment streams are netted out with the Fund receiving or paying, as the case may be, only the net amount of the two payments. The Fund will sell only covered futures contracts.

There is no assurance that these derivative strategies will be available at any time or that the Adviser and/or the Sub-Adviser will determine to use them for the Fund or, 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”).

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” (i.e., the change in the value of a particular dollar amount invested at a particular interest rate, in a particular foreign currency, 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.

Some, but not all, swaps may be cleared, in which case a central clearing counterparty stands between each buyer and seller and effectively guarantees performance of each contract, to the extent of its available resources for such purpose. Uncleared swaps have no such protection; each party bears the risk that its direct counterparty will default.

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 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 net asset value (“NAV”) of Common Shares. In addition, if the counterparty to an interest rate swap defaults, the Fund would not be able to use the anticipated net receipts under the swap to offset the interest payments on borrowings or the dividend payments on any outstanding preferred shares. Depending on whether the Fund would be entitled to receive net payments from the counterparty on the swap, which in turn would depend on the general state of short-term interest rates at that point in time, such a default could negatively impact the performance of Common Shares. In addition, at the time an interest rate swap transaction reaches its scheduled termination date, there is a risk that the Fund would not be able to obtain a replacement transaction or that the terms of the replacement would not be as favorable as on the expiring transaction. If this occurs, it could have a negative impact on the performance of Common Shares. The Fund could be required to prepay the principal amount of any borrowings. Such redemption or prepayment would likely result in the Fund seeking to terminate early all or a portion of any swap transaction. Early termination of a swap could result in a termination payment by or to the Fund.

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 Adviser and/or the Sub-Adviser 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. However, if a credit event occurs 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. However, if a credit event occurs, 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 economic 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 obligations directly, plus the additional risks related to obtaining investment exposure through a derivative instrument discussed below under “—Risks Associated with Swap Transactions.”

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.

Risks Associated with Swap Transactions. The use of swap transactions is a highly specialized activity which involves strategies and risks different from those associated with ordinary portfolio security transactions. If the Nuveen Fund Advisors and/or Nuveen Asset Management is incorrect in its forecasts of default risks, market spreads or other applicable factors or events, the investment performance of the Fund would diminish compared with what it would have been if these techniques were not used. As the protection seller in a credit default swap, the Fund effectively adds economic 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. The Fund generally may close out a swap, cap, floor, collar or other two-party contract only with its particular counterparty, and generally may transfer a position only with the consent of that counterparty. In addition, the price at which the Fund may close out such a two party contract may not correlate with the price change in the underlying reference asset. If the counterparty defaults, the Fund will have contractual remedies, but there can be no assurance that the counterparty will be able to meet its contractual obligations or that the Fund will succeed in enforcing its rights. It also is possible that developments in the derivatives market, including changes in government regulation, could adversely affect the Fund’s ability to terminate existing swap or other agreements or to realize amounts to be received under such agreements.

Futures and Options on Futures Generally. 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.

Bond Futures and Forward Contracts. Bond futures contracts are agreements in which one party agrees to deliver to the other an amount of cash equal to a specific dollar amount times the difference between the value of a specific bond at the close of the last trading day of the contract and the price at which the agreement is made. No physical delivery of securities is made. Forward contracts are agreements to purchase or sell a specified security or currency at a specified future date (or within a specified time period) and price set at the time of the contract. Forward contracts are usually entered into with banks, foreign exchange dealers or broker-dealers and are usually for less than one year, but may be renewed. Forward contracts are generally purchased or sold in OTC transactions.

Parties to a futures contract must make “initial margin” deposits to secure performance of the contract. There are also requirements to make “variation margin” deposits from time to time as the value of the futures contract fluctuates.

Options on Currency Futures Contracts. Currency futures contracts are standardized agreements between two parties to buy and sell a specific amount of a currency at a set price on a future date. While similar to currency forward contracts, currency futures contracts are traded on commodities exchanges and are standardized as to contract size and delivery date. An option on a currency futures contract gives the holder of the option the right to buy or sell a position in a currency futures contract, at a set price and on or before a specified expiration date. The ability to establish and close out positions on such options is subject to the maintenance of a liquid secondary market.

Index Futures. An index future is a bilateral agreement pursuant to which two parties agree to take or make delivery of an amount of cash—rather than any security—equal to a specified dollar amount times the difference between the index value at the close of the last trading day of the contract and the price at which the index future was originally written. Thus, an index future is similar to traditional financial futures except that settlement is made in cash. The Fund may invest in index futures or similar contracts if available in a form, with market liquidity and settlement and payment features, acceptable to such Fund.

Index Options. The Fund may also purchase put or call options on U.S. Government or bond index futures and enter into closing transactions with respect to such options to terminate an existing position. Options on index futures are similar to options on debt instruments except that an option on an index future gives the purchaser the right, in return for the premium paid, to assume a position in an index contract rather than an underlying security at a specified exercise price at any time during the period of the option. Upon exercise of the option, the delivery of the futures position by the writer of the option to the holder of the option will be accompanied by delivery of the accumulated balance of the writer’s futures margin account which represents the amount by which the market price of the index futures contract, at exercise, is less than the exercise price of the option on the index future.

Bond index futures and options transactions would be subject to risks similar to transactions in financial futures and options thereon as described above.

Limitations on the Use of Futures, Futures Options and Swaps. The Adviser has claimed, with respect to the Fund, the exclusion from the definition of “commodity pool operator” under the Commodity Exchange Act, as amended (“CEA”), provided by Commodity Futures Trading Commission (“CFTC”) Regulation 4.5 and is therefore not currently subject to registration or regulation as such under the CEA with respect to the Fund. In addition, the Sub-Adviser has claimed the exemption from registration as a commodity trading advisor provided by CFTC Regulation 4.14(a)(8) and is therefore not currently subject to registration or regulation as such under the CEA with respect to the Fund. In February 2012, the CFTC announced substantial amendments to certain exemptions, and to the conditions for reliance on those exemptions, from registration as a commodity pool operator. Under amendments to the exemption provided under CFTC Regulation 4.5, if the Fund uses futures, options on futures, or swaps other than for bona fide hedging purposes (as defined by the CFTC), the aggregate initial margin and premiums on these positions (after taking into account unrealized profits and unrealized losses on any such positions and excluding the amount by which options that are “in-the-money” at the time of purchase are “in-the-money”) may not exceed 5% of the Fund’s NAV, or alternatively, the aggregate net notional value of those positions may not exceed 100% of the Fund’s NAV (after taking into account unrealized profits and unrealized losses on any such positions). The CFTC amendments to Regulation 4.5 took effect on December 31, 2012, and the Fund intends to comply with amended Regulation 4.5’s requirements such that the Adviser will not be required to register as a commodity pool operator with the CFTC with respect to the Fund. The Fund reserves the right to employ futures, options on futures and swaps to the extent allowed by CFTC regulations in effect from time to time and in accordance with the Fund’s policies. However, the requirements for qualification as a “regulated investment company” under Subchapter M of the Internal Revenue Code of 1986, as amended (the “Code”), may limit the extent to which the Fund may employ futures, options on futures or swaps.

Repurchase Agreements

The Fund may enter into repurchase agreements (the purchase of a security coupled with an agreement to resell that security at a higher price) with respect to its permitted investments. The Fund’s repurchase agreements will provide that the value of the collateral underlying the repurchase agreement will always be at least equal to the repurchase price, including any accrued interest earned on the agreement, and will be marked-to-market daily. The agreed-upon repurchase price determines the yield during the Fund’s holding period.

Repurchase agreements are considered to be loans collateralized by the underlying security that is the subject of the repurchase contract. The Fund will only enter into repurchase agreements with registered securities dealers or domestic banks that, in Nuveen Asset Management’s opinion, present minimal credit risk. The risk to the Fund is limited to the ability of the issuer to pay the agreed-upon repurchase price on the delivery date; however, although the value of the underlying collateral at the time the transaction is entered into always equals or exceeds the agreed-upon repurchase price, if the value of the collateral declines there is a risk of loss of both principal and interest. In the event of default, the collateral may be sold but the Fund might incur a loss if the value of the collateral declines, and might incur disposition costs or experience delays in connection with liquidating the collateral. In addition, if bankruptcy proceedings are commenced with respect to the seller of the security, realization upon the collateral by the Fund may be delayed or limited. Nuveen Asset Management will monitor the value of the collateral at the time the transaction is entered into and at all times subsequent during the term of the repurchase agreement in an effort to determine that such value always equals or exceeds the agreed-upon repurchase price. In the event the value of the collateral declines below the repurchase price, Nuveen Asset Management will demand additional collateral from the issuer to increase the value of the collateral to at least that of the repurchase price, including interest.

Structured Notes

The Fund may utilize structured notes and similar instruments for investment purposes and also for hedging purposes. Structured notes are privately negotiated debt obligations where the principal and/or interest is determined by reference to the performance of a benchmark asset, market or interest rate (an “embedded index”), such as selected securities, an index of securities or specified interest rates, or the differential performance of two assets or markets. The terms of such structured instruments normally provide that their principal and/or interest payments are to be adjusted upwards or downwards (but not ordinarily below zero) to reflect changes in the embedded index while the structured instruments are outstanding. As a result, the interest and/or principal payments that may be made on a structured product may vary widely, depending upon a variety of factors, including the volatility of the embedded index and the effect of changes in the embedded index on principal and/or interest payments. The rate of return on structured notes may be determined by applying a multiplier to the performance or differential performance of the referenced index or indices or other assets. Application of a multiplier involves leverage that will serve to magnify the potential for gain and the risk of loss.

Other Investment Companies

The Fund may invest up to 10% of its Managed Assets in securities of other open-or closed-end investment companies (including exchange-traded funds) that invest primarily in municipal securities of the types in which the Fund may invest directly. In addition, the Fund may invest a portion of its Managed Assets in pooled investment vehicles (other than investment companies) that invest primarily in municipal securities of the types in which the Fund may invest directly. The Fund generally expects that it may invest in other investment companies and/or other pooled investment vehicles either during periods when it has large amounts of uninvested cash or during periods when there is a shortage of attractive, high yielding municipal securities available in the market. The Fund may invest in investment companies that are advised by the Adviser and/or the Sub-Adviser or their affiliates to the extent permitted by applicable law. As a shareholder in an investment company, the Fund will bear its ratable share of that investment company’s expenses and would remain subject to payment of its own management fees with respect to assets so invested. Common Shareholders would therefore be subject to duplicative expenses to the extent the Fund invests in other investment companies.

The Adviser and/or the Sub-Adviser will take expenses into account when evaluating the investment merits of an investment in an investment company relative to available municipal security investments. In addition, the securities of other investment companies may also be leveraged and will therefore be subject to the same leverage risks described herein. The NAV and market value of leveraged shares will be more volatile, and the yield to Common Shareholders will tend to fluctuate more than the yield generated by unleveraged shares.

Zero Coupon Bonds

The Fund may invest in zero coupon bonds. A zero coupon bond is a bond that typically does not pay interest for the entire life of the obligation or for an initial period after the issuance of the obligation. The market prices of zero coupon bonds are affected to a greater extent by changes in prevailing levels of interest rates and therefore tend to be more volatile in price than securities that pay interest periodically. In addition, because the Fund accrues income with respect to these securities prior to the receipt of such interest, it may have to dispose of portfolio securities under disadvantageous circumstances in order to obtain cash needed to pay income dividends in amounts necessary to avoid unfavorable tax consequences.

MANAGEMENT OF THE FUND

Trustees and Officers

The management of the Fund, including general supervision of the duties performed for the Fund under the Investment Management Agreement (as defined under “Investment Adviser, Sub-Adviser and Portfolio Managers—Investment Management Agreement and Related Fees”), is the responsibility of the Board. The number of Trustees of the Fund is twelve, all of whom are not interested persons (referred to herein as “Independent Trustees”). None of the Independent Trustees has ever been a director, trustee or employee of, or consultant to, Nuveen LLC (“Nuveen”), Nuveen Fund Advisors, Nuveen Asset Management, or their affiliates. The Board is divided into three classes, Class I, Class II and Class III, the Class I Trustees serving until the 2025 annual meeting, the Class II Trustees serving until the 2026 annual meeting and the Class III Trustees serving until the 2024 annual meeting, in each case until their respective successors are elected and qualified, as described below. Currently, Michael A. Forrester, Thomas J. Kenny, Margaret L. Wolff and Robert L. Young are slated in Class I, Joseph A. Boateng, Amy B. R. Lancellotta, John K. Nelson and Terence J. Toth are slated in Class II, and Joanne T. Medero, Albin F. Moschner, Loren M. Starr and Matthew Thornton III are slated in Class III. As each Trustee’s term expires, shareholders will be asked to elect Trustees and such Trustees shall be elected for a term expiring at the time of the third succeeding annual meeting subsequent to their election or thereafter in each case when their respective successors are duly elected and qualified. These provisions could delay for up to two years the replacement of a majority of the Board. See “Certain Provisions in the Declaration of Trust and By-Laws” in the prospectus.

The officers of the Fund serve annual terms through August of each year and are elected on an annual basis. The names, business addresses and years of birth of the Trustees and officers of the Fund, their principal occupations and other affiliations during the past five years, the number of portfolios each oversees and other trusteeships they hold are set forth below. Except as noted in the table below, the Trustees of the Fund are directors or trustees, as the case may be, of 216 Nuveen-sponsored registered investment companies (the “Nuveen Funds”), which includes 147 open-end mutual funds, 46 closed-end funds and 23 exchange-traded funds.

Board Leadership Structure and Risk Oversight

The Board oversees the operations and management of the Fund, including the duties performed for the Fund by Nuveen Fund Advisors. The Board has adopted a unitary board structure. A unitary board consists of one group of trustees who serves on the board of every fund in the complex. In adopting a unitary board structure, the Trustees seek to provide effective governance through establishing a board the overall composition of which will, as a body, possess the appropriate skills, diversity (including, among other things, gender, race and ethnicity), independence and experience to oversee the Fund’s business. With this overall framework in mind, when the Board, through its Nominating and Governance Committee discussed below, seeks nominees for the Board, the Trustees consider not only the candidate’s particular background, skills and experience, among other things, but also whether such background, skills and experience enhance the Board’s diversity and at the same time complement the Board given its current composition and the mix of skills and experiences of the incumbent Trustees. The Nominating and Governance Committee believes that the Board generally benefits from diversity of background (including, among other things, gender, race and ethnicity), skills, experience and views among Trustees, and considers this a factor in evaluating the composition of the Board, but has not adopted any specific policy on diversity or any particular definition of diversity.

The Board believes the unitary board structure enhances good and effective governance, particularly given the nature of the structure of the investment company complex. Funds in the same complex generally are served by the same service providers and personnel and are governed by the same regulatory scheme which raises common issues that must be addressed by the Trustees across the fund complex (such as compliance, valuation, liquidity, brokerage, trade allocation and risk management). The Board believes it is more efficient to have a single board review and oversee common policies and procedures which increases the Board’s knowledge and expertise with respect to the many aspects of fund operations that are complex-wide in nature. The unitary structure also enhances the Board’s influence and oversight over Nuveen Fund Advisors and other service providers.

In an effort to enhance the independence of the Board, the Board also has Co-Chairs who are Independent Trustees. The Board recognizes that a chair can perform an important role in setting the agenda for the Board, establishing the boardroom culture, establishing a point person on behalf of the Board for fund management and reinforcing the Board’s focus on the long-term interests of shareholders. The Board recognizes that a chair may be able to better perform these functions without any conflicts of interests arising from a position with Fund management. Accordingly, the trustees have elected Mr. Kenny to serve as an independent Co-Chair of the Board for a one-year term expiring on December 31, 2024, Mr. Toth to serve as an independent Co-Chair of the Board for a six-month term ending on June 30, 2024, and Mr. Young to serve as an independent Co-Chair of the Board for a six-month term from July 1, 2024 through December 31, 2024. Pursuant to the Fund’s By-Laws, the Chair shall perform all duties incident to the office of Chair of the Board and such other duties as from time to time may be assigned to him or her by the Trustees or the By-Laws. Specific responsibilities of the Co-Chairs include: (i) coordinating with Fund management in the preparation of the agenda for each meeting of the Board; (ii) presiding at all meetings of the Board and of the shareholders; and (iii) serving as a liaison with other trustees, the Trust’s officers and other Fund management personnel, and counsel to the independent trustees.

Although the Board has direct responsibility over various matters (such as advisory contracts and underwriting contracts), the Board also exercises certain of its oversight responsibilities through several committees that it has established and which report back to the full Board. The Board believes that a committee structure is an effective means to permit Trustees to focus on particular operations or issues affecting the Nuveen Funds, including risk oversight. More specifically, with respect to risk oversight, the Board has delegated matters relating to valuation, compliance and investment risk to certain committees (as summarized below). In addition, the Board believes that the periodic rotation of Trustees among the different committees allows the Trustees to gain additional and different perspectives of the Fund’s operations. The Board has established seven standing committees: the Executive Committee, the Dividend Committee, the Audit Committee, the Compliance, Risk Management and Regulatory Oversight Committee, the Investment Committee, the Nominating and Governance Committee and the Closed-End Funds Committee. The Board may also from time to time create ad hoc committees to focus on particular issues as the need arises. The membership and functions of the standing committees are summarized below. For more information on the Board, please visit www.nuveen.com/fundgovernance.

The Executive Committee, which meets between regular meetings of the Board, is authorized to exercise all of the powers of the Board. The members of the Executive Committee are Mr. Kenny and Mr. Young, Co-Chairs, Mr. Nelson and Mr. Toth. During the fiscal year ended March 31, 2024, the Executive Committee met eight times.

The Dividend Committee is authorized to declare distributions on each Nuveen Fund’s shares, including, but not limited to, regular and special dividends, capital gains and ordinary income distributions. The Dividend Committee operates under a written charter adopted and approved by the Board. The members of the Dividend Committee are Mr. Thornton, Chair, Ms. Lancellotta, Mr. Nelson and Mr. Starr. During the fiscal year ended March 31, 2024, the Dividend Committee met ten times.

The Board has an Audit Committee, in accordance with Section 3(a)(58)(A) of the Securities Exchange Act of 1934 (the “1934 Act”) that is composed of Independent Trustees who are also “independent” as that term is defined in the listing standards pertaining to closed-end funds of the NYSE. The Audit Committee assists the Board in: the oversight and monitoring of the accounting and reporting policies, processes and practices of the Nuveen Funds, and the audits of the financial statements of the Nuveen Funds; the quality and integrity of the financial statements of the Nuveen Funds; the Nuveen Funds’ compliance with legal and regulatory requirements relating to the Nuveen Funds’ financial statements; the independent auditors’ qualifications, performance and independence; and the pricing procedures of the Nuveen Funds and the internal valuation group of Nuveen. It is the responsibility of the Audit Committee to select, evaluate and replace any independent auditors (subject only to Board and, if applicable, shareholder ratification) and to determine their compensation. The Audit Committee is also responsible for, among other things, overseeing the valuation of securities comprising the Nuveen Funds’ portfolios. Subject to the Board’s general supervision of such actions, the Audit Committee addresses any valuation issues, oversees the Nuveen Funds’ pricing procedures and actions taken by Nuveen’s internal valuation group which provides regular reports to the Audit Committee, reviews any issues relating to the valuation of the Nuveen Funds’ securities brought to its attention, and considers the risks to the Nuveen Funds in assessing the possible resolutions of these matters. The Audit Committee may also consider any financial risk exposures for the Nuveen Funds in conjunction with performing its functions.

To fulfill its oversight duties, the Audit Committee receives and reviews annual and semi-annual reports and has regular meetings with the external auditors for the Nuveen Funds and the internal audit group at Nuveen. The Audit Committee also may review, in a general manner, the processes the Board or other Board committees have in place with respect to risk assessment and risk management as well as compliance with legal and regulatory matters relating to the Nuveen Funds’ financial statements. The Audit Committee operates under a written Audit Committee Charter (the “Charter”) adopted and approved by the Board, which Charter conforms to the listing standards of the NYSE. Members of the Audit Committee are independent (as set forth in the Charter) and free of any relationship that, in the opinion of the Trustees, would interfere with their exercise of independent judgment as an Audit Committee member. The members of the Audit Committee are Mr. Nelson, Chair, Mr. Boateng, Mr. Moschner, Mr. Starr, Ms. Wolff and Mr. Young, each of whom is an Independent Trustee of the Fund. Mr. Boateng, Mr. Moschner, Mr. Nelson, Mr. Starr and Mr. Young have each been designated as an “audit committee financial expert” as defined by the rules of the SEC. A copy of the Charter is available at https://www.nuveen.com/fund-governance. During the fiscal year ended March 31, 2024, the Audit Committee met fourteen times.

The Compliance, Risk Management and Regulatory Oversight Committee (the “Compliance Committee”) is responsible for the oversight of compliance issues, risk management and other regulatory matters affecting the Fund that are not otherwise under or within the jurisdiction of the other committees. The Board has adopted and periodically reviews policies and procedures designed to address the Fund’s compliance and risk matters. As part of its duties, the Compliance Committee: reviews the policies and procedures relating to compliance matters and recommends modifications thereto as necessary or appropriate to the full Board; develops new policies and procedures as new regulatory matters affecting the Fund arise from time to time; evaluates or considers any comments or reports from examinations from regulatory authorities and responses thereto; and performs any special reviews, investigations or other oversight responsibilities relating to risk management, compliance and/or regulatory matters as requested by the Board.

In addition, the Compliance Committee is responsible for risk oversight, including, but not limited to, the oversight of general risks related to investments which are not reviewed by other committees, such as liquidity and derivatives usage; risks related to product structure elements, such as leverage; techniques that may be used to address the foregoing risks, such as hedging and swaps and Fund operational risk and risks related to the overall operation of the Nuveen enterprise and, in each case, the controls designed to address or mitigate such risks. In assessing issues brought to the Compliance Committee’s attention or in reviewing a particular policy, procedure, investment technique or strategy, the Compliance Committee evaluates the risks to the Fund in adopting a particular approach or resolution compared to the anticipated benefits to the Fund and its shareholders. In fulfilling its obligations, the Compliance Committee meets on a quarterly basis, and at least once a year in person. The Compliance Committee receives written and oral reports from the Fund’s Chief Compliance Officer (“CCO”) and meets privately with the CCO at each of its quarterly meetings. The CCO also provides an annual report to the full Board regarding the operations of the Fund’s and other service providers’ compliance programs as well as any recommendations for modifications thereto. Matters not addressed at the committee level are addressed directly by the full Board. The Compliance Committee operates under a written charter adopted and approved by the Board. The members of the Compliance Committee are Ms. Wolff, Chair, Mr. Forrester, Mr. Kenny, Ms. Lancellotta, Ms. Medero, Mr. Thornton and Mr. Toth. During the fiscal year ended March 31, 2024, the Compliance Committee met six times.

The Nominating and Governance Committee is responsible for seeking, identifying and recommending to the Board qualified candidates for election or appointment to the Board. In addition, the Nominating and Governance Committee oversees matters of corporate governance, including the evaluation of Board performance and processes, the assignment and rotation of committee members, and the establishment of corporate governance guidelines and procedures, to the extent necessary or desirable, and matters related thereto. Although the unitary Board and committee structures have been developed over the years and the Nominating and Governance Committee believes these structures have provided efficient and effective governance, the Nominating and Governance Committee recognizes that, as demands on the Board evolve over time (such as through an increase in the number of funds overseen or an increase in the complexity of the issues raised), the Nominating and Governance Committee must continue to evaluate the Board and committee structures and their processes and modify the foregoing as may be necessary or appropriate to continue to provide effective governance. Accordingly, the Nominating and Governance Committee has a separate meeting each year to, among other things, review the Board and committee structures, their performance and functions, and recommend any modifications thereto or alternative structures or processes that would enhance the Board’s governance over the Fund’s business.

In addition, the Nominating and Governance Committee, among other things: makes recommendations concerning the continuing education of Trustees; monitors performance of legal counsel and other service providers; establishes and monitors a process by which security holders are able to communicate in writing with Trustees; and periodically reviews and makes recommendations about any appropriate changes to Trustee compensation. In the event of a vacancy on the Board, the Nominating and Governance Committee receives suggestions from various sources, including shareholders, as to suitable candidates. Suggestions should be sent in writing to William Siffermann, Manager of Fund Board Relations, Nuveen, 333 West Wacker Drive, Chicago, Illinois 60606. The Nominating and Governance Committee sets appropriate standards and requirements for nominations for new Trustees and each nominee is evaluated using the same standards. However, the Nominating and Governance Committee reserves the right to interview any and all candidates and to make the final selection of any new Trustees. In considering a candidate’s qualifications, each candidate must meet certain basic requirements, including relevant skills and experience, time availability (including the time requirements for due diligence meetings with internal and external sub-advisers and service providers) and, if qualifying as an Independent Trustee candidate, independence from Nuveen Fund Advisors, Nuveen Asset Management, underwriters or other service providers, including any affiliates of these entities. These skill and experience requirements may vary depending on the current composition of the Board, since the goal is to ensure an appropriate range of skills, diversity and experience, in the aggregate. Accordingly, the particular factors considered and weight given to these factors will depend on the composition of the Board and the skills and backgrounds of the incumbent Trustees at the time of consideration of the nominees. All candidates, however, must meet high expectations of personal integrity, independence, governance experience and professional competence. All candidates must be willing to be critical within the Board and with management and yet maintain a collegial and collaborative manner toward other Trustees. The Nominating and Governance Committee operates under a written charter adopted and approved by the Board, a copy of which is available on the Funds’ website at https://www.nuveen.com/fund-governance, and is composed entirely of Independent Trustees, who are also “independent” as defined by NYSE listing standards. The members of the Nominating and Governance Committee are Mr. Kenny and Mr. Young, Co-Chairs, Mr. Boateng, Mr. Forrester, Ms. Lancellotta, Ms. Medero, Mr. Moschner, Mr. Nelson, Mr. Starr, Mr. Thornton, Mr. Toth and Ms. Wolff. During the fiscal year ended March 31, 2024, the Nominating and Governance Committee met six times.

The Investment Committee is responsible for the oversight of Fund performance, investment risk management and other portfolio-related matters affecting the Fund which are not otherwise the jurisdiction of the other Board committees. As part of such oversight, the Investment Committee reviews the Fund’s investment performance and investment risks, which may include, but is not limited to, an evaluation of Fund performance relative to investment objectives, benchmarks and peer group; a review of risks related to portfolio investments, such as exposures to particular issuers, market sectors, or types of securities, as well as consideration of other factors that could impact or are related to Fund performance; and an assessment of Fund objectives, policies and practices as such may relate to Fund performance. In assessing issues brought to the committee’s attention or in reviewing an investment policy, technique or strategy, the Investment Committee evaluates the risks to the Fund in adopting or recommending a particular approach or resolution compared to the anticipated benefits to the Fund and its shareholders.

In fulfilling its obligations, the Investment Committee receives quarterly reports from the investment oversight and the investment risk groups at Nuveen. Such groups also report to the full Board on a quarterly basis and the full Board participates in further discussions with fund management at its quarterly meetings regarding matters relating to Fund performance and investment risks, including with respect to the various drivers of performance and Fund use of leverage and hedging. Accordingly, the Board directly and/or in conjunction with the Investment Committee oversees the investment performance and investment risk management of the Fund. The Investment Committee operates under a written charter adopted and approved by the Board. This committee is composed of the independent Trustees of the Fund. Accordingly, the members of the Investment Committee are Mr. Boateng and Ms. Lancellotta, Co-Chairs, Mr. Forrester, Mr. Kenny, Ms. Medero, Mr. Moschner, Mr. Nelson, Mr. Starr, Mr. Thornton, Mr. Toth, Ms. Wolff and Mr. Young. During the fiscal year ended March 31, 2024, the Investment Committee met four times.

The Closed-End Funds Committee was established by the Board in 2012 and is responsible for assisting the Board in the oversight and monitoring of the Nuveen funds that are registered as closed-end management investment companies (“Closed-End Funds”). The Closed-End Funds Committee may review and evaluate matters related to the formation and the initial presentation to the Board of any new Closed-End Fund and may review and evaluate any matters relating to any existing Closed-End Fund. The Closed-End Funds Committee receives updates on the secondary closed-end fund market and evaluates the premiums and discounts of the Nuveen closed-end funds, including the Fund, at each quarterly meeting. The Closed-End Funds Committee reviews, among other things, the premium and discount trends in the broader closed-end fund market, by asset category and by closed-end fund; the historical total return performance data for the Nuveen closed-end funds, including the Fund, based on net asset value and price over various periods; the volatility trends in the market; the use of leverage by the Nuveen closed-end funds, including the Fund; the distribution data of the Nuveen closed-end funds, including the Fund, and as compared to peer averages; and a summary of common share issuances, if any, and share repurchases, if any, during the applicable quarter by the Nuveen closed-end funds, including the Fund. The Closed-End Funds Committee regularly engages in more in-depth discussions of premiums and discounts of the Nuveen closed-end funds. Additionally, the Closed-End Funds Committee members participate in in-depth workshops to explore, among other things, actions to address discounts of the Nuveen closed-end funds, potential share repurchases and available leverage strategies and their use. The Closed-End Funds Committee operates under a written charter adopted and approved by the Board. The members of the Closed-End Funds Committee are Mr. Moschner, Chair, Mr. Kenny, Ms. Lancellotta, Mr. Nelson, Mr. Starr, Mr. Toth, Mr. Young and Ms. Wolff. During the fiscal year ended March 31, 2024, the Closed-End Funds Committee met four times.
