PROSPECTUS

Shares

Nuveen Core Plus Impact Fund

Common Shares

$20.00 per Share

The Fund.    Nuveen Core Plus Impact Fund (the “Fund”) is a newly organized, diversified, closed-end management investment company. The Fund’s investment objective is to seek total return through high current income and capital appreciation, while giving special consideration to certain impact and environmental, social and governance (“ESG”) criteria. There can be no assurance that the Fund will achieve its investment objective or that the Fund’s investment strategies will be successful.

Fund Strategies.    The Fund seeks to achieve its investment objective by investing in fixed-income investments of any type, including asset-backed securities, corporate bonds, preferred securities, residential and commercial mortgage-backed securities, taxable and tax-exempt municipal bonds, senior loans and loan participations and assignments, sovereign debt instruments, debt securities issued by supranational agencies, and U.S. government securities (securities issued or guaranteed by the U.S. Government or its agencies or instrumentalities). Substantially all of the portfolio’s investments are subject to Nuveen’s proprietary public market impact framework criteria (the “Impact Criteria”) or certain ESG criteria. The Impact Criteria are designed to generate positive, measurable social and environmental impact alongside a financial return. These investments provide direct access to issuers and/or individual projects across four social and environmental themes: Affordable Housing, Community and Economic Development, Renewable Energy and Climate Change, and Natural Resources. The portion of the Fund invested in accordance with the Impact Criteria is not additionally subject to ESG criteria provided by a third party. The Fund’s Impact Criteria focuses on investments that will be selected based on the same financial criteria used in selecting the Fund’s other fixed-income investments. The Fund’s ESG criteria are generally implemented based on data provided by independent research vendor(s). The ESG evaluation process employed by the Fund favors issuers with leadership in ESG performance relative to their peers. Typically, environmental assessment categories include climate change, natural resource use, waste management and environmental opportunities. Social evaluation categories include human capital, product safety and social opportunities. Governance assessment categories include corporate governance, business ethics and government and public policy. How well companies adhere to international norms and principles and involvement in major ESG controversies (examples of which may relate to the environment, customers, human rights and community, labor rights and supply chain, and governance) are other considerations. The Fund’s portfolio will be actively managed and will seek to deliver a direct and measurable positive social and environmental impact as well as ESG leadership.

No Prior History.    Because the Fund is newly organized, its common shares of beneficial interest (“Common Shares”) have no history of public trading. Shares of closed-end investment companies frequently trade at a discount from their net asset value (“NAV”). This risk of loss due to the discount may be greater for investors who expect to sell their shares in a relatively short period after completion of the public offering. It is anticipated that the Fund’s Common Shares will be approved for listing on the New York Stock Exchange, subject to notice of issuance. The trading or “ticker” symbol is “NPCT.”

This prospectus sets forth concisely information about the Fund that a prospective investor should know before investing, and should be retained for future reference. Investing in the Fund’s Common Shares involves certain risks. The Fund’s anticipated exposure to below investment grade securities (high yield or junk bonds) involves special risks, including an increased risk with respect to the issuer’s capacity to pay interest, dividends and repay principal. You could lose some or all of your investment. See “Risks ” beginning on page 75 of this prospectus. Certain of these risks are summarized in “Prospectus Summary—Special Risk Considerations” beginning on page 20 of this prospectus.

Neither the Securities and Exchange Commission (“SEC”) nor any state securities commission has approved or disapproved of these securities or determined if this prospectus is truthful or complete. Any representation to the contrary is a criminal offense.

(notes on following page)

The underwriters expect to deliver the Common Shares to purchasers on or about                     , 2021.

Nuveen Securities

The date of this prospectus is                     , 2021.

(notes from previous page)

Investment Policies.    Under normal market conditions, the Fund will invest at least 80% of its Managed Assets (as defined on page 9) in fixed-income investments of any type. The Fund may invest up to 50% of its Managed Assets in below investment grade investments (such investments are commonly referred to as “high-yield” or “junk” and are rated BB+/Ba1 or lower at the time of investment or are unrated but judged by the Fund’s subadviser to be of comparable quality) with no more than 10% of its Managed Assets in investments rated CCC/Caa or lower, including defaulted investments, at the time of investment. Below investment grade investments are regarded as having predominately speculative characteristics with respect to the issuer’s capacity to pay interest or dividends and repay principal, which implies higher price volatility and default risk than investment grade instruments of comparable terms and duration. The Fund may invest no more than 30% of its Managed Assets in investments of foreign issuers that are located in emerging market countries.

The Fund may seek to provide exposure to certain Regulation S securities by investing in a Cayman Islands exempted company (the “Subsidiary”), a wholly owned subsidiary of the Fund, which will invest primarily in Regulation S securities. Regulation S securities are debt or equity securities of U.S. and foreign issuers offered through private offerings exempt from registration with the SEC pursuant to Regulation S of the Securities Act of 1933, as amended. Offerings of Regulation S securities may be conducted outside of the United States, and Regulation S securities may be relatively less liquid as a result of legal or contractual restrictions on resale. The Subsidiary is advised by the Fund’s sub-adviser, Nuveen Asset Management, LLC, and has the same investment objective as the Fund. The Subsidiary may also hold cash and invest in other instruments, including fixed-income investments, either as investments or to serve as margin or collateral for the Subsidiary’s Regulation S positions.

Leverage.    The Fund anticipates using leverage in order to pursue its investment objective. The Fund may use leverage to the extent permitted by the Investment Company Act of 1940, as amended. The Fund may source leverage initially and throughout the life of the Fund through a number of methods including through borrowings, issuing preferred shares of beneficial interest, the issuance of debt securities, entering into reverse repurchase agreements (effectively a borrowing), and investing 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. The sources of leverage will vary depending on market conditions. The Fund anticipates using such leverage in an aggregate amount equal to approximately     % of the Fund’s Managed Assets, if current market conditions persist. In pursuit of its investment objective, the Fund has the ability to reduce or increase the amount and type of leverage based upon changes in market conditions, composition of the Fund’s holdings and remaining time until the Fund’s termination date. The Fund’s leverage ratio will vary from time to time based upon such changes in the amount of leverage used and variations in the value of the Fund’s holdings. In addition, the Fund may use derivatives that have the economic effect of leverage. The use of

leverage creates special risks for common shareholders. See “Leverage,” “Risks—Fund Level Risks—Leverage Risk,” “Portfolio Composition and Other Information—Municipal Bonds—Inverse Floating Rate Securities” and “Risks—Portfolio Level Risks—Inverse Floating Rate Securities Risk.” 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.

Limited Term.    The Fund’s Declaration of Trust provides that the Fund terminates on the first business day of the month that follows the twelfth anniversary of the effective date of the Fund’s initial registration statement, which is currently anticipated to be [                ] 1, 2033 (the “Stated Termination Date”); however, the Board of Trustees of the Fund (the “Board of Trustees”) may vote to extend the term of the Fund for up to two one year periods (in the event of any such extension, the termination date shall be referred to as the “Extended Termination Date” and the later of the Stated Termination Date and the Extended Termination Date is referred to as the “Termination Date”); furthermore, the Board of Trustees may determine to cause the Fund to conduct a tender offer to all holders of outstanding Common Shares as of a date within the 18 months preceding the Termination Date (an “Eligible Tender Offer”). At the time of the Eligible Tender Offer, the Board of Trustees will determine the minimum net assets the Fund must retain following the Eligible Tender Offer to ensure the Fund’s continued viability (the “Termination Threshold”). If the number of Common Shares properly tendered in an Eligible Tender Offer would result in the Fund’s net assets totaling greater than the Termination Threshold, the Fund will purchase all Common Shares properly tendered and not withdrawn pursuant to the terms of the Eligible Tender Offer. If an Eligible Tender Offer is completed, the Board of Trustees may, in its sole discretion and without any action by the shareholders of the Fund, provide that the Fund may continue without limitation of time, subject to the terms and conditions described herein. If the Termination Threshold would not be satisfied, an Eligible Tender Offer will not be completed, the Fund will, no later than the Termination Date, cease investment operations, retire or redeem its leverage facilities, liquidate its investment portfolio (to the extent possible) and, on or after the Termination Date, the Fund will distribute all of its liquidated net assets to common shareholders of record in one or more distributions. The Fund’s investment objective is not designed to return to common shareholders their original NAV or purchase price. See “Prospectus Summary—Limited Term; Eligible Tender Offer” and “Risks—Fund Level Risks—Limited Term and Tender Offer Risks.”

Fund Distributions.    The Fund currently intends to implement a managed distribution policy by declaring monthly distributions stated in terms of a fixed cents per Common Share that would be composed of net investment income and a supplemental amount generally representing the potential for capital appreciation, which may take the form of realized capital gains or, possibly, a return of capital, which may (but will not necessarily) represent unrealized capital gains. Monthly distributions that include such supplemental amounts representing potential capital appreciation are sometimes referred to as “managed distributions.” The Fund’s managed distribution policy is being implemented pursuant to an exemptive order issued by the SEC, which permits the Fund to distribute long-term capital gains to shareholders more frequently than once per year. The Fund will seek to establish a distribution rate that roughly corresponds to Nuveen Fund Advisors’ projections of the total return that could reasonably be expected to be generated by the Fund over an extended period of time, although the distribution rate will not be directly dependent on the amount of income earned or capital gains realized by the Fund. Nuveen Fund Advisors, in making such projections, may consider long-term historical returns of the types of securities in the portfolio, current and expected portfolio composition, current market sentiment, and a variety of other factors. As portfolio and market conditions change, the rate of distributions on the Common Shares and the Fund’s distribution policy could change.

To the extent that the total return of the Fund’s overall strategy exceeds the distribution rate for an extended period, the Fund may be in a position either to increase the distribution rate or to distribute supplemental amounts to shareholders, or both. Conversely, if the total return of the Fund’s overall strategy is less than the distribution rate for an extended period of time, the Fund will effectively be drawing upon its assets to meet payments prescribed by its distribution policy. The Fund may make additional distributions, or include within the Fund’s final distribution for each calendar year, amounts representing any remaining net investment income and net realized capital gains not distributed during the year. See “Distributions” for additional information.

Beginning on January 1, 2021, as permitted by regulations adopted by the SEC, paper copies of the Fund’s shareholder reports will not be sent by mail, unless you specifically request paper copies of the shareholder reports from the Fund or from your financial intermediary, such as a broker-dealer or bank. Instead, shareholder reports will be available on the Fund’s website at http://www.nuveen.com, and you will be notified by mail each time a report is posted and provided with a website link to access the report. If you already elected to receive shareholder reports electronically, you will not be affected by this change and you need not take any action. You may elect to receive shareholder reports and other communications from the Fund electronically anytime by contacting your financial intermediary, such as a broker-dealer or bank, through which you hold your Common Shares. Shareholders may at any time elect to receive paper copies of the shareholder reports without charge by contacting your financial intermediary or by contacting the Fund by calling (800) 257-8787 or by writing to 333 West Wacker Drive, Chicago, Illinois 60606.

You should read this prospectus, which contains important information about the Fund, before deciding whether to invest, and retain it for future reference. A Statement of Additional Information, dated                , 2021, as amended or supplemented through the effective date of this prospectus, containing additional information about the Fund, has been filed with the SEC and is incorporated by reference in its entirety into this prospectus. You may request a free copy of the Statement of Additional Information, the table of contents of which is on page 120 of this prospectus, annual and semi-annual reports to shareholders, when available, and other information about the Fund, and make shareholder inquiries by calling (800) 257-8787 or by writing to the Fund, or from the Fund’s website (www.nuveen.com).

The Fund’s Common Shares do not represent a deposit or obligation of, and are not guaranteed or endorsed by, any bank or other insured depository institution, and are not federally insured by the Federal Deposit Insurance Corporation, the Federal Reserve Board or any other government agency.

You should rely only on the information contained or incorporated by reference in this prospectus. The Fund has not, and the underwriters have not, authorized anyone to provide you with different information. If anyone provides you with different or inconsistent information, you should not rely on it. The Fund is not, and the underwriters are not, making an offer of these securities in any jurisdiction where the offer is not permitted. You should not assume that the information contained in this prospectus is accurate as of any date other than the date on the front of this prospectus. The Fund’s business, financial condition and prospects may have changed since that date.

The Fund’s subadviser, Nuveen Asset Management, LLC (“Nuveen Asset Management”), seeks to ensure that the Fund’s investments are consistent with its Impact Criteria and/or ESG criteria, but it cannot guarantee that this will always be the case for every Fund investment. Consistent with its responsibilities, Nuveen Asset Management has the right to change the ESG vendor(s) at any time and to add to the

The Fund is not restricted from investing in any investments issued or guaranteed by the U.S. government or its agencies or instrumentalities. The Fund considers investments in these investments to be consistent with its investment and social objectives.

Municipal Bonds.    The Fund may invest in taxable and tax-exempt municipal securities, including municipal bonds, and notes and other securities issued by states, cities and local authorities and certain possessions and territories of the United States (such as Puerto Rico and Guam) to finance or refinance public purpose projects such as roads, schools, and water supply systems. Municipal bonds may also be issued to finance and refinance privately owned facilities or projects deemed to serve a public purpose. Municipal bonds may be issued on a long-term basis to provide long-term 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 revenue. Municipal bonds may also be issued to finance projects on a short-term interim basis, anticipating repayment with the proceeds of long-term debt.

In pursuit of its investment objective, the Fund has the ability to reduce or increase the amount and type of leverage based upon changes in market conditions, composition of the Fund’s holdings and remaining time until the Fund’s Termination Date. The Fund’s leverage ratio will vary from time to time based upon such changes in the amount of leverage used and 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.

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

SUMMARY OF FUND EXPENSES

The purpose of the table and example below is to help you understand all fees and expenses that you, as a Common Shareholder, would bear directly or indirectly. The expenses shown in the table are based on estimated amounts for the Fund’s first full year of operations and assume that the Fund issues                          Common Shares in this offering. The Annual Expenses table below assumes the use of leverage in an aggregate amount equal to     % of the Fund’s Managed Assets (after their use), and shows Fund expenses as a percentage of net assets attributable to Common Shares. The Fund’s actual expenses may vary from the estimated expenses shown in the table and, all other things being equal, will increase as a percentage of net assets attributable to Common Shares if the Fund issues less than                      Common Shares. See “Management of the Fund.”

45

Example

The following example illustrates the expenses that you would pay on a $1,000 investment in Common Shares, assuming (1) total annual expenses of             % of net assets attributable to Common Shares and (2) a 5% annual return. The example assumes that the estimated Total Annual Expenses set forth in the Annual Expenses table are accurate and that all dividends and distributions are reinvested at Common Share NAV. Moreover, the Fund’s actual rate of return may be greater or less than the hypothetical 5% return shown in the example.

The example should not be considered a representation of future expenses. Actual expenses may be higher or lower.

THE FUND

The Fund is a newly organized, diversified, closed-end management investment company registered under the Investment Company Act of 1940, as amended (the “1940 Act”). The Fund was organized as a Massachusetts business trust on December 4, 2020, pursuant to the Fund’s Declaration of Trust (the “Declaration of Trust”). On December 21, 2020, the Fund filed an amendment to the Declaration of Trust to change the name of the Fund. As a newly organized entity, the Fund has no operating history. The Fund’s principal office is located at 333 West Wacker Drive, Chicago, Illinois 60606, and its telephone number is (800) 257-8787.

USE OF PROCEEDS

The net proceeds of this offering of Common Shares will be approximately $                     ($                     if the Underwriters exercise the over-allotment option in full). Nuveen Fund Advisors has agreed to (i) reimburse all organizational expenses of the Fund and (ii) pay the Fund’s offering costs. The Fund will invest the net proceeds of this offering in accordance with the Fund’s investment objective and policies (as stated below) as soon as practicable after the completion of this offering. The Fund currently anticipates that it will be able to invest substantially all of the net proceeds in investments that meet the Fund’s investment objective and policies within three months after completion of this offering; however, under certain circumstances, including but not limited to, adverse market conditions, lack of supply and lack of ability to secure the most attractive investment opportunities for investors, the Fund may take up to six months after completion of this offering to invest substantially all of the net proceeds in investments that meet the Fund’s investment objective and policies. During the period in which the net proceeds of this offering are first being invested (the “invest-up period”), the Fund may invest up to 100% of its Managed Assets in short-term investments, including high quality, short-term securities, or may invest in short-, intermediate-, or long-term U.S. Treasury securities. During the invest-up period, the Fund may also purchase securities issued by exchange-traded funds (“ETFs”) that invest primarily in investments of the types in which the Fund may invest directly. Any such investments in ETFs will be in compliance with the limitations imposed by the 1940 Act, the rules promulgated thereunder, or pursuant to any exemptive relief obtained thereunder.

THE FUND’S INVESTMENTS

Investment Objective

The Fund’s investment objective is to seek total return through high current income and capital appreciation, while giving special consideration to certain impact and environmental, social and governance (“ESG”) criteria. There can be no assurance that the Fund will achieve its investment objective or that the Fund’s investment strategies will be successful.

Fund Strategies

The Fund’s portfolio will be actively managed and will seek to deliver a direct and measurable positive social and environmental impact as well as ESG leadership. Substantially all of the portfolio’s investments are subject to Nuveen’s proprietary public market impact framework criteria (the “Impact Criteria”) or certain ESG criteria.

Impact Criteria

The fixed-income investments invested according to the Impact Criteria provide direct exposure to issuers and/or individual projects with social or environmental benefits. These investments will be selected based on the same financial criteria used in selecting the Fund’s other fixed-income investments. The portion of the Fund invested in accordance with this Impact Criteria is not additionally subject to ESG criteria provided by a third party.

47

The Impact Criteria are designed to generate positive, measurable social and environmental impact alongside a financial return. These investments are intended to provide access to the following four social and environmental themes:

(1) Affordable Housing: Investments issued to support the financing of low and moderate income

housing loans, transit oriented development, walkable communities, or mixed-use development projects.

(2) Community & Economic Development: Investments issued to support financial services, hospital/ medical services, educational services, community centers, reconstruction activities, urban revitalization, humanitarian, disaster, and international aid services inclusive of underserved and/or economically disadvantaged communities.

(3) Renewable Energy & Climate Change: Investments issued to finance new or expand existing renewable energy projects (including hydroelectric, solar and wind), smart grid and other projects designed to make power generation and transmission systems more efficient, and other energy efficiency projects which seek to reduce greenhouse gas emissions.

(4) Natural Resources: Investments issued to support land conservation, sustainable forestry and agriculture, remediation and redevelopment of polluted or contaminated sites, sustainable waste management projects, water infrastructure including improvement of clean drinking water supplies and/or sewer systems, and sustainable building projects.

ESG Criteria and Evaluation Process

The Fund’s ESG criteria are generally implemented based on data provided by independent research vendor(s). In those limited cases where independent ESG criteria are not available for certain types of investments or for certain issuers, these investments may nonetheless be eligible for investment by the Fund should they meet certain internal ESG criteria. Substantially all issuers not otherwise meeting the Impact Criteria described above must meet or exceed minimum ESG performance standards to be eligible for investment by the Fund.

The corporate issuer evaluation process favors companies with leadership in ESG performance relative to their peers. Typically, environmental assessment categories include climate change, natural resource use, waste management and environmental opportunities. Social evaluation categories include human capital, product safety and social opportunities. Governance assessment categories include corporate governance, business ethics and government and public policy. How well companies adhere to international norms and principles and involvement in major ESG controversies (examples of which may relate to the environment, customers, human rights and community, labor rights and supply chain, and governance) are other considerations.

The ESG evaluation process with respect to corporate issuers is conducted on an industry-specific basis and involves the identification of key performance indicators, which are given more or less relative weight compared to the broader range of potential assessment categories. When ESG concerns exist, the evaluation process gives careful consideration to how companies address the risks and opportunities they face in the context of their sector or industry and relative to their peers. The Fund will not generally invest in companies significantly involved in certain business activities including, but not limited to, the production of alcohol, tobacco, military weapons, firearms, nuclear power, thermal coal, and gambling products and services.

The ESG evaluation process with respect to government issuers favors issuers with leadership in ESG performance relative to all peers. Typically, environmental assessment categories include the issuer’s ability to protect, harness, and supplement its natural resources, and to manage environmental vulnerabilities and externalities. Social assessment categories include the issuer’s ability to develop a healthy, productive, and stable

48

workforce and knowledge capital, and to create a supportive economic environment. Governance assessment categories include the issuer’s institutional capacity to support long-term stability and well-functioning financial, judicial, and political systems, and capacity to address environmental and social risks. The government ESG evaluation process is conducted on a global basis and reflects how an issuer’s exposure to and management of ESG risk factors may affect the long-term sustainability of its economy.

Other Considerations and Investments

While the Fund may invest in issuers that meet these criteria, it is not required to invest in every issuer that meets these criteria. In addition, concerns with respect to one ESG assessment category may not automatically eliminate an issuer from being considered an eligible investment. The Impact Criteria, the ESG criteria and the universe of investments that the Fund utilizes may be changed without the approval of the Fund’s shareholders.

Nuveen Asset Management seeks to ensure that the Fund’s investments are consistent with its Impact Criteria and/or ESG criteria, but it cannot guarantee that this will always be the case for every Fund investment. Consistent with its responsibilities, Nuveen Asset Management has the right to change the ESG vendor(s) at any time and to add to the number of vendors providing the universe of eligible companies. Investing on the basis of Impact Criteria or ESG criteria is qualitative and subjective by nature, and there can be no assurance that the Impact Criteria utilized by Nuveen, the ESG criteria utilized by the Fund’s ESG vendor(s), or any judgment exercised by Nuveen Asset Management will reflect the beliefs or values of any particular investor.

The Fund may also invest in certain asset-backed securities, mortgage-backed securities and other securities that represent interests in assets such as pools of mortgage loans, automobile loans or credit card receivables. These securities are typically issued by legal entities established specifically to hold assets and to issue debt obligations backed by those assets. Asset-backed or mortgage-backed securities are normally created or “sponsored” by banks or other institutions or by certain government-sponsored enterprises such as the Federal National Mortgage Association (“Fannie Mae” or “FNMA”) or Federal Home Loan Mortgage Corporation (“Freddie Mac” or “FHLMC”). The Fund does not take into consideration whether the sponsor of an asset-backed security in which it invests meets the Impact Criteria or the ESG criteria. That is because asset-backed securities represent interests in pools of loans, and not of the ongoing business enterprise of the sponsor. It is therefore possible that the Fund could invest in an asset-backed or mortgage-backed security sponsored by a bank or other financial institution in which the Fund could not invest directly. However, the investments underlying an asset-backed or mortgage-backed security will generally meet or exceed the Impact Criteria or the ESG criteria.

The Fund’s Impact Criteria or ESG criteria will apply to derivatives and other instruments that have economic characteristics similar to the Fund’s fixed-income investments. However, neither the Impact Criteria nor the ESG criteria will apply to the Fund’s investments in derivatives used for hedging purposes.

The Fund is not restricted from investing in any investments issued or guaranteed by the U.S. government or its agencies or instrumentalities. The Fund considers investments in these investments to be consistent with its investment and social objectives.

There can be no assurance that the Fund’s strategies will be successful.

Portfolio Contents

The Fund generally invests in a portfolio of fixed-income investments of any type, including asset-backed securities, corporate bonds, preferred securities, residential and commercial mortgage-backed securities, taxable and tax-exempt municipal bonds, senior loans and loan participations and assignments, sovereign debt instruments, debt securities issued by supranational agencies, and U.S. government securities (securities issued or guaranteed by the U.S. Government or its agencies or instrumentalities).

49

The Fund’s investments will include investment grade and below investment grade investments. Below investment grade investments (such investments are commonly referred to as “high yield” or “junk”) generally provide high income in an effort to compensate investors for their higher risk of default, which is the failure to make required interest or principal payments. Additionally, the Fund’s portfolio may contain restricted and illiquid investments (i.e., investments that are not readily marketable), including, but not limited to, restricted investments (investments the disposition of which is restricted under the federal securities laws), investments that may be resold only pursuant to Rule 144A under the Securities Act of 1933, as amended (“1933 Act”) that are deemed to be illiquid, and certain repurchase agreements. Restricted investments may be sold only in privately negotiated transactions or in a public offering with respect to which a registration statement is in effect under the 1933 Act.

The Fund may also invest directly in Regulation S securities that are freely tradable in the U.S. Regulation S securities are debt or equity securities of U.S. and foreign issuers offered through private offerings exempt from registration with the Securities and Exchange Commission (“SEC”) pursuant to Regulation S of the 1933 Act. Offerings of Regulation S securities may be conducted outside of the United States, and Regulation S securities may be relatively less liquid as a result of legal or contractual restrictions on resale.

The Fund may invest in securities of other open-end or closed-end investment companies, including ETFs, that invest primarily in the types of investments in which the Fund may invest directly.

The Fund may invest without limitation in credit default swaps, and may enter into credit default swaps as either a buyer or a seller. The credit default swaps in which the Fund may invest include credit default swap indices (“CDX”) and those in which the underlying reference instrument is the debt obligation of a single reference issuer (“single-name CDS”). A CDX is a portfolio of credit default swaps with similar characteristics, such as credit default swaps on high-yield bonds. Certain CDX instruments are subject to mandatory central clearing and exchange trading, which may reduce counterparty credit risk and increase liquidity compared to other credit default swaps or CDX transactions. Unlike other types of credit default swaps, single-name CDS do not have the benefit of diversification across many issuers.

In addition to credit default swaps, the Fund also may invest in certain derivative instruments in pursuit of its investment objective. Such instruments include financial futures contracts and options thereon, forward contracts, swaps (with varying terms, including interest rate swaps), options on swaps and other fixed-income derivative instruments. Nuveen Asset Management may use derivative instruments to attempt to hedge some of the risk of the Fund’s investments, to limit exposure to losses due to changes to foreign currency exchange rates or as a substitute for a position in the underlying asset. See “Portfolio Composition and Other Information—Derivatives.”

The Fund may also invest in other types of investments and debt instruments described in this prospectus and the SAI. See “Portfolio Composition and Other Information” for additional information on the types of investments in which the Fund may invest.

Investment Policies

Under normal circumstances:

50

The foregoing policies apply only at the time of any new investment.

“Managed Assets” means the total assets of the Fund, minus the sum of its accrued liabilities (other than Fund liabilities incurred for the express purpose of creating leverage). Total assets for this purpose shall include assets attributable to the Fund’s use of leverage (whether or not those assets are reflected in the Fund’s financial statements for purposes of generally accepted accounting principles), and derivatives will be valued at their market value.

The portion of the Fund’s assets invested in below investment grade investments (such investments are commonly referred to as “high yield” or “junk”) may vary over time. Below investment grade investments are regarded as having predominately speculative characteristics with respect to the issuer’s capacity to pay interest or dividends, and repay principal, which implies higher price volatility and default risk than investment grade instruments of comparable terms and duration. These investments generally provide higher income than investment grade securities in an effort to compensate investors for their higher risk of default, which is the issuer’s failure to make required interest, dividend or principal payments on the investments. For purposes of the investment limitations in this prospectus, an investment’s rating is determined using the middle rating of Moody’s Investor Services, Inc. (“Moody’s”), Standard & Poor’s Ratings Services, a Standard & Poor’s Financial Services LLC business (“Standard & Poor’s” or “S&P”) and Fitch Ratings, a part of the Fitch Group (“Fitch”) if all three nationally recognized statistical rating organizations (“NRSROs”) rate the investment. If ratings are provided by only two of those NRSROs, the lower rating is used to determine the rating. If only one of those NRSROs provides a rating, that rating is used. If an investment is not rated by any NRSRO, the rating determined by Nuveen Asset Management is used. Investment rating limitations are considered to apply only at the time of investment and will not be considered violated unless an excess or deficiency occurs or exists immediately after and as a result of an acquisition of investments.

Nuveen Asset Management may determine that it is in the best interest of shareholders to pursue a workout arrangement with respect to investments that are in default or involved in bankruptcy or insolvency proceedings, which may involve making loans to the issuer or another party, or purchasing an equity or other interest from the issuer or another party, or other related or similar steps involving the investment of additional monies.

For purposes of the limitations on emerging market debt investments, the Fund will classify an issuer based on the issuer’s country of origin, generally as determined by an unaffiliated, recognized financial data provider. An issuer’s country of origin is based on a number of criteria, such as the issuer’s country of domicile or country in which the issuer conducts its primary operations, the primary exchange on which its investments trade, the location from which the majority of the issuer’s revenue comes, and the issuer’s reporting currency. The term “emerging market” describes any country or market that is generally considered to be emerging or developing by major organizations in the international financial community, such as the International Finance Corporation, or by financial industry analysts like MSCI, Inc., which compiles the MSCI Emerging Markets Index, and J.P. Morgan Chase & Co., which compiles several fixed-income emerging markets benchmarks; or other countries or markets with similar emerging characteristics. Emerging markets can include every nation in the world except the United States, Canada, Japan, Australia, New Zealand and most nations located in Western Europe. Notwithstanding the foregoing, the fixed-income portfolio management team generally views Israel as an emerging market.

The Fund may seek to provide exposure to Regulation S securities that are not freely tradable in the U.S. by investing in a Cayman Islands exempted company (the “Subsidiary”), a wholly owned subsidiary of the Fund,

51

which will invest primarily in Regulation S securities. The Subsidiary is advised by Nuveen Asset Management and has the same investment objective as the Fund. The Subsidiary may also hold cash and invest in other instruments, including fixed income securities, either as investments or to serve as margin or collateral for the Subsidiary’s Regulation S positions.

The Subsidiary will be managed pursuant to compliance policies and procedures that are the same, in all material respects, as the policies and procedures adopted by the Fund. As a result, Nuveen Asset Management, in managing the Subsidiary’s portfolio, will be subject to the same investment policies and restrictions that apply to the management of the Fund, and, in particular, to the requirements relating to portfolio leverage, liquidity, brokerage, and the timing and method of the valuation of the Subsidiary’s portfolio investments and shares of the Subsidiary. These policies and restrictions are described in detail throughout this Prospectus. The Fund and Subsidiary will test for compliance with certain investment restrictions on a consolidated basis, except that with respect to its investments in certain securities that may involve leverage, the Subsidiary will comply with asset segregation requirements to the same extent as the Fund.

Nuveen Asset Management will provide investment management and other services to the Subsidiary. Nuveen Asset Management will not receive separate compensation from the Subsidiary for providing it with investment management or administrative services. However, the Fund will pay Nuveen Asset Management based on the Fund’s assets, including the assets invested in the Subsidiary. The Subsidiary will also enter into separate contracts for the provision of custody and audit services with the same or with affiliates of the same service providers that provide those services to the Fund.

The financial statements of the Subsidiary will be consolidated with the Fund’s financial statements in the Fund’s annual and semi-annual reports. The Fund’s annual and semi-annual reports, when produced, will be distributed to Common Shareholders, and copies of the reports will be available on the Fund’s website (http://www.nuveen.com) free of. Please refer to the SAI for additional information about the organization and management of the Subsidiary.

Other Policies

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

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. All of the Fund’s other investment policies are not considered to be fundamental by the Fund and can be changed by the Board of Trustees of the Fund (the “Board of Trustees”) without a vote of the shareholders. The Fund cannot change its fundamental policies without the approval of the holders of a “majority of the outstanding” Common Shares. When used with respect to particular shares of the Fund, a “majority of the outstanding” shares means (i) 67% or more of the shares present at a meeting, if the holders of more than 50% of the shares are present or represented by proxy or (ii) more than 50% of the shares, whichever is less.

Limited Term; Eligible Tender Offer

The Declaration of Trust provides that the Fund will have a limited period of existence and will terminate as of the first business day of the month that follows the twelfth anniversary of the effective date of the Fund’s initial registration statement, which is currently anticipated to be                  1, 2033 (the “Stated Termination

52

Date”); provided that the Board of Trustees may, in its sole discretion and without any action by the shareholders of the Fund, by vote of a majority of the then Board of Trustees with notice to the shareholders, extend the Fund’s term for up to two one year periods (in the event of any such extension, the termination date shall be referred to as the “Extended Termination Date” and the later of the Stated Termination Date and the Extended Termination Date is referred to as the “Termination Date”); furthermore, notwithstanding the foregoing, if the Board of Trustees determines to cause the Fund to conduct an Eligible Tender Offer (as defined below), and the Eligible Tender Offer is completed, the Board of Trustees may, in its sole discretion and without any action by the shareholders of the Fund, by vote of a majority of the then Board of Trustees, provide that the Fund may continue without limitation of time, subject to the terms and conditions described below. If an Eligible Tender Offer is not conducted, the Fund will, no later than the Termination Date, cease investment operations, retire or redeem its leverage facilities, liquidate its investment portfolio (to the extent possible) and, on or after the Termination Date, the Fund will distribute all of its liquidated net assets to Common Shareholders of record in one or more distributions.

Eligible Tender Offer. The Declaration of Trust provides that an eligible tender offer (an “Eligible Tender Offer”) is a tender offer by the Fund to all holders of outstanding Common Shares as of a date within the 18 months preceding the Termination Date. If the tender offer is completed, Shareholders who properly tender Common Shares in the Eligible Tender Offer will receive a purchase price equal to the NAV per share on the expiration date of the Eligible Tender Offer. In an Eligible Tender Offer, the Fund will offer to purchase all outstanding Common Shares held by each Common Shareholder. At the time of the Eligible Tender Offer, the Board of Trustees will determine the Termination Threshold. The Termination Threshold will be based on prevailing market conditions at the time of the Eligible Tender Offer.

If the number of Common Shares properly tendered in an Eligible Tender Offer would result in the Fund’s net assets totaling greater than the Termination Threshold, the Fund will purchase all Common Shares properly tendered and not withdrawn pursuant to the terms of the Eligible Tender Offer and following the completion of such Eligible Tender Offer, the Board of Trustees may, in its sole discretion and without any action by the shareholders of the Fund, provide that the Fund may continue without limitation of time. See “Risks—Fund Level Risks—Limited Term and Tender Offer Risks.” In making this decision, the Board of Trustees will take such actions with respect to the Fund’s continued operations as it deems to be in the best interests of the Fund, based on market conditions at such time, the extent of Common Shareholder participation in the Eligible Tender Offer and all other factors deemed relevant by the Board of Trustees in consultation with Nuveen Fund Advisors, taking into account that Nuveen Fund Advisors may have a potential conflict of interest in seeking to convert the Fund to a fund with a continued existence without limitation of time.

If the number of properly tendered Common Shares would result in the Fund’s net assets totaling less than the Termination Threshold if the Eligible Tender Offer were consummated, the Eligible Tender Offer will be terminated, no Common Shares will be repurchased pursuant to the Eligible Tender Offer and the Fund will begin (or continue) liquidating its investment portfolio and proceed to terminate on the Termination Date.

An Eligible Tender Offer would be made, and Common Shareholders would be notified thereof, in accordance with the Declaration of Trust, the 1940 Act, the 1934 Act, and the applicable tender offer rules thereunder (including Rule 13e-4 and Regulation 14E under the 1934 Act).

Termination, Liquidation. Unless the Fund’s existence is continued without limitation of time, as described under “—Eligible Tender Offer” above, no later than the Termination Date, the Fund will cease investment operations, retire or redeem its leverage facilities, liquidate its investment portfolio (to the extent possible) and, on or after the Termination Date, the Fund will distribute all of its liquidated net assets to Common Shareholders of record in one or more distributions. In determining whether to extend the Fund’s term, the Board of Trustees may consider a number of factors, including, without limitation, whether the Fund would be unable to sell its assets at favorable prices in a time frame consistent with the Termination Date due to lack of market liquidity or other adverse market conditions, or whether market conditions are such that it is reasonable to believe that, with

53

an extension, the Fund’s remaining assets would appreciate and generate income in an amount that, in the aggregate, is meaningful relative to the cost and expense of continuing the Fund’s operations.

Nuveen Fund Advisors and Nuveen Asset Management will seek to manage the Fund’s investment portfolio consistent with the Fund’s obligation to cease operations on the Termination Date. To that end, Nuveen Fund Advisors and Nuveen Asset Management intend to seek investments that they reasonably expect can be sold or otherwise exited at favorable prices on or before the Termination Date. However, there is no assurance that a market or other exit strategy will be available for the Fund’s less liquid investments. As the Termination Date approaches, Nuveen Fund Advisors and Nuveen Asset Management expect to seek to liquidate the Fund’s less liquid investments. As a result, based on prevailing market conditions, available investment opportunities and other factors, the Fund may invest the proceeds from the sale of such investments in money market mutual funds, cash, cash equivalents, securities issued or guaranteed by the U.S. government or its instrumentalities or agencies, high quality short-term money market instruments, short-term debt securities, certificates of deposit, bankers’ acceptances and other bank obligations, commercial paper or other liquid debt securities. As a result, as the Termination Date approaches, the Fund’s monthly cash distributions may decline, and there can be no assurance that the Fund will achieve its investment objective or that its investment strategies will be successful.

Depending on a variety of factors, including the performance of the Fund’s investment portfolio over the period of its operations, the amount distributed to Common Shareholders in connection with its termination or paid to participating Common Shareholders upon completion of an Eligible Tender Offer may be less, and potentially significantly less, than your original investment. The Fund’s final distribution to Common Shareholders on the Termination Date and the amount paid to participating Common Shareholders upon completion of an Eligible Tender Offer will be based upon the Fund’s NAV at such time, and initial investors and any investors that purchase Common Shares after the completion of this offering may receive less, and potentially significantly less, than their original investment.

Because the Fund’s assets will be liquidated in connection with its termination or to pay for Common Shares tendered in an Eligible Tender Offer, the Fund may be required to sell portfolio investments when it otherwise would not, including at times when market conditions are not favorable, which may cause the Fund to lose money. The Fund will make a distribution on the Termination Date of all cash raised from the liquidation of its assets prior to that time. However, given the nature of certain of the Fund’s investments, the Fund may be unable to liquidate certain of its investments until after the Termination Date. In this case, the Fund may make one or more additional distributions after the Termination Date of any cash received from the ultimate liquidation of those investments. This would delay distribution payments, perhaps for an extended period of time, and there can be no assurance that the total value of the cash distribution made on the Termination Date and such subsequent distributions, if any, will equal the Fund’s NAV on the Termination Date, depending on the ultimate results of such post-Termination Date asset liquidations. If, as a result of lack of market liquidity or other adverse market conditions, the Board of Trustees determines it is in the best interests of the Fund, the Fund may transfer any portfolio investments that remain unsold on the Termination Date to a liquidating trust and distribute interests in such liquidating trust to Common Shareholders as part of the Fund’s final distribution. Interests in the liquidating trust are expected to be nontransferable, except by operation of law. The liquidating trust will seek to liquidate such remaining investments for the benefit of the Common Shareholders as soon as practicable following the Termination Date. However, there can be no assurance as to the timing of or the value obtained from such liquidation. See “Risks—Fund Level Risks—Limited Term and Tender Offer Risks.”

PORTFOLIO COMPOSITION AND OTHER INFORMATION

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

Corporate Bonds

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

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

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

Emerging Market Issuers

The Fund will invest in investments of emerging market issuers. The Fund’s emerging market investments include a broad range of investments of emerging market issuers such as government bonds, corporate bonds, and other sovereign or quasi-sovereign debt instruments. The Fund will classify an issuer of an investment based on the issuer’s country of origin, generally as determined by an unaffiliated, recognized financial data provider. An issuer’s country or origin is based on a number of criteria, such as the issuer’s country of domicile or country in which the issuer conducts its primary operations, the primary exchange on which its securities trade, the location from which the majority of the issuer’s revenue comes, and the issuer’s reporting currency. The term “emerging market” describes any country or market that is generally considered to be emerging or developing by major organizations in the international financial community, such as the International Finance Corporation, or by financial industry analysts like MSCI, Inc., which compiles the MSCI Emerging Markets Index, and J.P. Morgan Chase & Co., which compiles several fixed-income emerging markets benchmarks; or other countries or markets with similar emerging characteristics. Emerging markets can include every nation in the world except the United States, Canada, Japan, Australia, New Zealand and most nations located in Western Europe. Notwithstanding the foregoing, the fixed-income portfolio management team generally views Israel as an emerging market.

The Fund’s emerging market debt investments may also include secured loans, unsecured loans, senior loans, second lien loans, subordinated debt and sukuk debt instruments.

55

Sukuk are certificates structured to comply with Sharia law and its investment principles. These certificates usually represent the beneficial ownership interest in a portfolio of eligible existing or future tangible or intangible assets (“underlying assets”). In a typical sukuk, a special purpose vehicle (“SPV”) issues certificates to investors in exchange for their capital. The SPV transfers the capital to or for the benefit of the entity that is raising the capital (the “obligor”) in exchange for the underlying assets of the obligor that are held in trust by the SPV. The obligor is obligated, usually through a series of contracts, to make periodic payments to investors through the SPV over a specified period of time and a final payment to investors through the SPV on a date certain. Obligors of sukuk include financial institutions and corporations, foreign governments and agencies of foreign governments, including issuers in emerging markets.

Sovereign and Supranational Securities

Sovereign securities are issued or guaranteed by foreign sovereign governments or their agencies, authorities, political subdivisions or instrumentalities, and supranational agencies. A supranational agency is a multinational union or association in which member countries cede authority and sovereignty on a limited number of matters to the group, whose decisions are binding upon its members. Quasi-sovereign securities typically are issued by companies or agencies that may receive financial support or backing from a local government or in which the government owns a majority of the issuer’s voting shares.

The ability of a foreign sovereign issuer, especially in an emerging market country, to make timely and ultimate payments on its debt obligations will be strongly influenced by the sovereign issuer’s balance of payments, including export performance, its access to international credits and investments, fluctuations of interest rate and the extent of its foreign reserves. A country whose exports are concentrated in a few commodities or whose economy depends on certain strategic imports could be vulnerable to fluctuations in international prices of these commodities or imports. To the extent that a country receives payment for its export in currencies other than dollars, its ability to make debt payments denominated in dollars could be adversely affected. If a sovereign issuer cannot generate sufficient earnings from foreign trade to service its external debt, it may need to depend on continuing loans and aid from foreign governments, commercial banks and multinational organizations. There may be no bankruptcy proceedings similar to those in the U.S. by which defaulted interest may be collected.

The Fund also may invest in debt obligations issued or guaranteed by supranational agencies organized or supported by several national governments, such as the International Bank for Reconstruction and Development (the “World Bank”), the Inter-American Development Bank, the Asian Development Bank, and the European Investment Bank. In addition, the Portfolio may purchase debt obligations of foreign corporations or financial institutions, such as Yankee bonds (dollar-denominated bonds sold in the United States by foreign companies), Samurai bonds (yen-denominated bonds sold in Japan by non-Japanese issuers), and Euro bonds (bonds not issued in the country (and possibly not the currency of the country) of the issuer).

Municipal Bonds

The Fund may invest in taxable 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 federal income tax. Municipal bonds are often issued by state and local governmental entities to finance or refinance public projects such as roads, schools, and water supply systems. Municipal bonds 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 and pollution control projects. Municipal bonds 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 bonds may also be issued to

56

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, zero coupon, capital appreciation bonds, tender option bonds, and residual interest bonds or inverse floating rate securities; or acquired through investments in pooled vehicles, partnerships or other investment companies.

Inverse Floating Rate Securities. Inverse floating rate securities (sometimes referred to as “inverse floaters”) 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 formed for the purpose of holding municipal bonds. The special purpose trust typically sells two classes of beneficial interests or securities: floating rate securities (sometimes referred to as short-term floaters or tender option bonds) and inverse floating rate securities (sometimes referred to as inverse floaters or residual interest securities). Both classes of beneficial interests are represented by certificates. The short-term floating rate securities have first priority on the cash flow from the municipal bonds held by the special purpose trust. Typically, a third party, such as a bank, broker-dealer or other financial institution, grants the floating rate security holders the option, at periodic intervals, to tender their securities to the institution and receive the face value thereof. As consideration for providing the option, the financial institution receives 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 institution granting the tender option will not be obligated to accept tendered short-term floaters in the event of certain defaults or a significant downgrade in the credit rating assigned to the bond issuer. For its inverse floating rate investment, the Fund receives the residual cash flow from the special purpose trust. Because the holder of the short-term floater is generally assured liquidity at the face value of the security, the Fund as the holder of the inverse floater assumes the interest rate cash flow risk and the market value risk associated with the municipal security deposited into the special purpose 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 in relation to the value of the residual inverse floaters that are issued by the special purpose trust. In addition, all voting rights and decisions to be made with respect to any other rights relating to the municipal bonds held in the special purpose trust are passed through to the Fund, as the holder of the residual interest securities.

Because increases in the interest rate on the short-term floaters reduce the residual interest paid on inverse floaters, and because fluctuations in the value of the municipal bond deposited in the special purpose trust affect the value of the inverse floater only, and not the value of the short-term floater issued by the trust, and because fluctuations in the value of the municipal bond deposited in the special purpose trust affect the value of the inverse floater only, and not the value of the short-term floater issued by the trust, inverse floaters’ value is generally more volatile than that of fixed rate bonds. The market price of inverse floating rate securities is generally more volatile than the underlying securities due to the leveraging effect of this ownership structure. These securities generally will underperform the market of fixed rate bonds in a rising interest rate environment (i.e., when bond values are falling), but tend to outperform the market of fixed rate bonds when interest rates decline or remain relatively stable. Although volatile, inverse floaters typically offer the potential for yields exceeding the yields available on fixed rate bonds with comparable credit quality, coupon, call provisions and maturity. Inverse floaters have varying degrees of liquidity based upon, among other things, the liquidity of the underlying securities deposited in a special purpose trust.

The Fund may invest in inverse floating rate securities issued by special purpose trusts that have recourse to the Fund. In Nuveen Fund Advisors’ and Nuveen Asset Management’s discretion, the Fund may enter into a separate shortfall and forbearance agreement with the liquidity provider to a special purpose trust. The Fund may enter into such recourse agreements (i) when the liquidity provider to the special purpose trust requires such an agreement because the level of leverage in the trust exceeds the level that the liquidity provider is willing support absent such an agreement; and/or (ii) to seek to prevent the liquidity provider from collapsing the trust in the event that the municipal obligation held in the trust has declined in value. Such an agreement would require the Fund to reimburse the third party granting liquidity to the floating rate security holders the special purpose trust, upon

57

termination of the trust issuing the inverse floater, the difference between the liquidation value of the bonds held in the trust and the principal amount due to the holders of floating rate interests. Such agreements may expose the Fund to a risk of loss that exceeds its investment in the inverse floating rate securities. Absent a shortfall and forbearance agreement, the Fund would not be required to make such a reimbursement. If the Fund chooses not to enter into such an agreement, the special purpose trust could be liquidated and the Fund could incur a loss.

The Fund will segregate or earmark liquid assets with its custodian in accordance with the 1940 Act to cover its obligations with respect to its investments in special purpose trusts.

Investments in inverse floating rate securities have the economic effect of leverage. The use of leverage creates special risks for Common Shareholders. See “Leverage” and “Risks—Portfolio Level Risks—Inverse Floating Rate Securities Risk.”

Asset-Backed Securities

ABS are securities that are primarily serviced by the cash flows of a discrete pool of receivables or other financial assets, either fixed or revolving, that by their terms convert into cash within a finite time period. Asset-backed securitization is a financing technique in which financial assets, in many cases themselves less liquid, are pooled and converted into instruments that may be offered and sold in the capital markets. In a basic securitization structure, an entity, often a financial institution, originates or otherwise acquires a pool of financial assets, either directly or through an affiliate. It then sells the financial assets, again either directly or through an affiliate, to a specially created investment vehicle that issues securities “backed” or supported by those financial assets, which securities are ABS. Payment on the ABS depends primarily on the cash flows generated by the assets in the underlying pool and other rights designed to assure timely payment, such as liquidity facilities, guarantees or other features generally known as credit enhancements. While residential mortgages were the first financial assets to be securitized in the form of MBS, non-mortgage related securitizations have grown to include many other types of financial assets, such as credit card receivables, auto loans and student loans.

U.S. Government Obligations

Securities issued or guaranteed by U.S. Government agencies and instrumentalities include obligations that are supported by: (a) the full faith and credit of the U.S. Treasury (e.g., direct pass-through certificates issued or guaranteed by the Government National Mortgage Association (“Ginnie Mae” or “GNMA”); (b) the limited authority of the issuer or guarantor to borrow from the U.S. Treasury (e.g., obligations of Federal Home Loan Banks); or (c) only the credit of the issuer or guarantor (e.g., obligations of Freddie Mac). In the case of obligations not backed by the full faith and credit of the U.S. Treasury, the agency issuing or guaranteeing the obligation is principally responsible for ultimate repayment.

Agencies and instrumentalities that issue or guarantee debt securities and that have been established or sponsored by the U.S. Government include, in addition to those identified above, the Bank for Cooperatives, the Export-Import Bank, the Federal Farm Credit System, the Federal Intermediate Credit Banks, the Federal Land Banks, Fannie Mae and the Student Loan Marketing Association.

Mortgage-Backed Securities, including Commercial Mortgage-Backed Securities

The Fund may invest in mortgage-backed securities. A mortgage-backed security is a type of pass-through security, which is a security representing pooled debt obligations repackaged as interests that pass income through an intermediary to investors. In the case of mortgage-backed securities, the ownership interest is in a pool of mortgage loans. Commercial mortgage-backed securities (“CMBS”) are backed by a pool of mortgages on commercial property.

58

Mortgage-backed securities are most commonly issued or guaranteed by Ginnie Mae, Fannie Mae or Freddie Mac, but may also be issued or guaranteed by other private issuers.

GNMA is a government-owned corporation that is an agency of the U.S. Department of Housing and Urban Development. It guarantees, with the full faith and credit of the United States, full and timely payment of all monthly principal and interest on its mortgage-backed securities.

Government-related guarantors (i.e., not backed by the full faith and credit of the United States government) include FNMA and FHLMC. FNMA is a government-sponsored corporation. FNMA purchases conventional (i.e., not insured or guaranteed by any government agency) residential mortgages from a list of approved seller/servicers which include state and federally chartered savings and loan associations, mutual savings banks, commercial banks and credit unions and mortgage bankers. Pass-through securities issued by FNMA are guaranteed as to timely payment of principal and interest by FNMA, but are not backed by the full faith and credit of the United States Government. FHLMC was created by Congress in 1970 for the purpose of increasing the availability of mortgage credit for residential housing. It is a government-sponsored corporation that issues Participation Certificates (“PCs”), which are pass-through securities, each representing an undivided interest in a pool of residential mortgages. FHLMC guarantees the timely payment of interest and ultimate collection of principal, but PCs are not backed by the full faith and credit of the United States government.

On September 6, 2008, the Federal Housing Finance Agency (“FHFA”) placed FNMA and FHLMC into conservatorship. As the conservator, FHFA succeeded to all rights, titles, powers and privileges of FNMA and FHLMC and of any stockholder, officer or director of FNMA and FHLMC with respect to FNMA and FHLMC and the assets of FNMA and FHLMC. FHFA selected a new chief executive officer and chairman of the board of directors for each of FNMA and FHLMC. In addition, the U.S. Treasury Department agreed to provide FNMA and FHLMC with up to $100 billion of capital each to ensure that they are able to continue to provide ongoing liquidity to the U.S. home mortgage market. FNMA and FHLMC are continuing to operate as going concerns while in conservatorship and each remain liable for all of its obligations, including its guaranty obligations, associated with its mortgage-backed securities.

Mortgage-backed securities issued by private issuers, whether or not such obligations are subject to guarantees by the private issuer, may entail greater risk than obligations directly or indirectly guaranteed by the U.S. government. Any investments a Fund makes in mortgage-related securities that are issued by private issuers have some exposure to subprime loans as well as to the mortgage and credit markets generally. Private issuers include commercial banks, savings associations, mortgage companies, investment banking firms, finance companies and special purpose finance entities (called special purpose vehicles or structured investment vehicles) and other entities that acquire and package mortgage loans for resale as mortgage-related securities. Unlike mortgage-related securities issued or guaranteed by the U.S. government or one of its sponsored entities, mortgage-related securities issued by private issuers do not have a government or government sponsored entity guarantee, but may have credit enhancement provided by external entities such as banks or financial institutions or achieved through the structuring of the transaction itself. Examples of such credit support arising out of the structure of the transaction include: (1) the issuance of senior and subordinated securities (e.g., the issuance of securities by a special purpose vehicle in multiple classes or “tranches,” with one or more classes being senior to other subordinated classes as to the payment of principal and interest, with the result that defaults on the underlying mortgage loans are borne first by the holders of the subordinated class); (2) the creation of “reserve funds” (in which case cash or investments, sometimes funded from a portion of the payments on the underlying mortgage loans, are held in reserve against future losses); and (3) “overcollateralization” (in which case the scheduled payments on, or the principal amount of, the underlying mortgage loans exceeds that required to make payment of the securities and pay any servicing or other fees). However, there can be no guarantee that credit enhancements, if any, will be sufficient to prevent losses in the event of defaults on the underlying mortgage loans.

In addition, mortgage-related securities that are issued by private issuers are not subject to the underwriting requirements for the underlying mortgages that are applicable to those mortgage related securities that have a

59

government or government-sponsored entity guarantee. As a result, the mortgage loans underlying private mortgage-related securities may, and frequently do, have less favorable collateral, credit risk or other underwriting characteristics than government or government sponsored mortgage-related securities and have wider variances in a number of terms including interest rate, term, size, purpose and borrower characteristics. Privately issued pools more frequently include second mortgages, high loan-to-value mortgages and manufactured housing loans. The coupon rates and maturities of the underlying mortgage loans in a private-label mortgage-related securities pool may vary to a greater extent than those included in a government guaranteed pool, and the pool may include subprime mortgage loans. Subprime loans refer to loans made to borrowers with weakened credit histories or with a lower capacity to make timely payments on their loans. For these reasons, the loans underlying these securities have had in many cases higher default rates than those loans that meet government underwriting requirements.

The risk of non-payment is greater for mortgage-related securities that are backed by mortgage pools that contain subprime loans, but a level of risk exists for all loans. Market factors adversely affecting mortgage loan repayments may include a general economic turndown, high unemployment, a general slowdown in the real estate market, a drop in the market prices of real estate, or an increase in interest rates resulting in higher mortgage payments by holders of adjustable rate mortgages.

Privately issued mortgage-related securities are generally less liquid than obligations directly or indirectly guaranteed by the U.S. government or a government-sponsored entity, especially when there is a perceived weakness in the mortgage and real estate market sectors. Without an active trading market, mortgage-related securities held in a Fund’s portfolio may be particularly difficult to value because of the complexities involved in assessing the value of the underlying mortgage loans. The average life of a mortgage-backed security is likely to be substantially less than the original maturity of the mortgage pools underlying the securities. Prepayments of principal by mortgagors and mortgage foreclosures will usually result in the return of the greater part of principal invested far in advance of the maturity of the mortgages in the pool or can result in credit losses.

Loans

The Fund may invest in loans, including senior secured loans, unsecured and/or subordinated loans, loan participations and unfunded contracts. These loans are typically made by or issued to corporations primarily to finance acquisitions, refinance existing debt, support organic growth, or pay out dividends, and are typically originated by large banks and are then syndicated out to institutional investors as well as to other banks. Loans typically bear interest at a floating rate, although some loans pay a fixed rate. Floating rate loans have interest rates that reset periodically, typically monthly or quarterly. The interest rates on floating rate loans are generally based on a percentage above the London Inter-Bank Offered Rate, a U.S. bank’s prime or base rate, the overnight federal funds rate or another rate. Due to their lower place in the borrower’s capital structure, unsecured and/or subordinated loans involve a higher degree of overall risk than senior bank loans of the same borrower. Loan participations are loans that are shared by a group of lenders. Unfunded commitments are contractual obligations by lenders (such as the Fund) to loan an amount in the future or that is due to be contractually funded in the future. Assignments may be arranged through private negotiations between potential assignees and potential assignors, and the rights and obligations acquired by the purchaser of an assignment may differ from, and be more limited than, those held by the assigning lender.

Loans may have restrictive covenants limiting the ability of a borrower to further encumber its assets. The types of covenants included in loan agreements generally vary depending on market conditions, the creditworthiness of the borrower, the nature of the collateral securing the loan and other factors. Such restrictive covenants normally allow for early intervention and proactive mitigation of credit risk by providing lenders with the ability to (1) intervene and either prevent or restrict actions that may potentially compromise the borrower’s ability to repay the loan and/or (2) obtain concessions from the borrower in exchange for waiving or amending a particular covenant. Loans with fewer or weaker restrictive covenants may limit the Fund’s ability to intervene or obtain additional concessions from borrowers.

60

Senior Loans

The Fund may invest in (i) senior loans made by banks or other financial institutions to foreign corporations, partnerships and other business entities (each a “Borrower” and, collectively, “Borrowers”), (ii) assignments of such interests in senior loans, or (iii) participation interests in senior loans. Senior loans hold the most senior position in the capital structure of a Borrower, are typically secured with specific collateral and have a claim on the assets and/or stock of the Borrower that is senior to that held by subordinated debt holders and stockholders of the Borrower. The capital structure of a Borrower may include senior loans, senior and junior subordinated debt, preferred stock and common stock issued by the Borrower, typically in descending order of seniority with respect to claims on the Borrower’s assets. The proceeds of senior loans primarily are used by Borrowers to finance leveraged buyouts, recapitalizations, mergers, acquisitions, stock repurchases, refinancings, internal growth and for other corporate purposes. A senior loan is typically originated, negotiated and structured by a U.S. or foreign commercial bank, insurance company, finance company or other financial institution (“Agent”) for a lending syndicate of financial institutions which typically includes the Agent (“Lenders”). The Agent typically administers and enforces the senior loans on behalf of the other Lenders in the syndicate. In addition, an institution, typically but not always the Agent, holds any collateral on behalf of the Lenders. The Fund normally will rely primarily on the Agent to collect principal of and interest on a Senior Loan. Also, the Fund usually will rely on the Agent to monitor compliance by the Borrower with the restrictive covenants in a loan agreement.

Senior loans in which the Fund invests generally pay interest at rates that are redetermined periodically at short-term intervals by reference to a base lending rate, plus a premium. Senior loans typically have rates of interest that are redetermined either daily, monthly, quarterly or semi-annually by reference to a base lending rate plus a premium or credit spread. These base lending rates are primarily London Inter-Bank Offered Rate (“LIBOR”) (of any tenor, but typically between one month and six months, and currency), and secondarily the prime rate offered by one or more major U.S. banks (the “Prime Rate”) and the certificate of deposit (“CD”) rate or other base lending rates used by commercial lenders. As adjustable rate loans, the frequency of how often a senior loan resets its interest rate will impact how closely such senior loans track current market interest rates. Senior loans typically have a stated term of between one and eight years. In the experience of Nuveen Asset Management, the average life of senior loans in recent years has been approximately two years because of prepayments.

In July 2017, the Financial Conduct Authority (the authority that regulates LIBOR) announced it intends to stop compelling banks to submit rates for the calculation of LIBOR after 2021. Alternatives to LIBOR are established or in development in most major currencies, including the Secured Overnight Financing Rate (“SOFR”), which is intended to replace U.S. dollar LIBOR. It is unknown if SOFR will become the primary base lending rate for senior loans.

The Fund primarily purchases senior loans by assignment from a participant in the original syndicate of lenders or from subsequent assignees of such interests. The purchaser of an assignment typically succeeds to all the rights and obligations under the loan agreement with the same rights and obligations as the assigning Lender. Assignments may, however, be arranged through private negotiations between potential assignees and potential assignors, and the rights and obligations acquired by the purchaser of an assignment may differ from, and be more limited than, those held by the assigning Lender.

The Fund may purchase participation interests in the original syndicate making senior loans. Loan participation interests typically represent direct participations in a loan to a corporate Borrower, and generally are offered by banks or other financial institutions or lending syndicates. The Fund may participate in such syndications, or can buy part of a senior loan, becoming a part Lender. When purchasing a participation interest, the Fund assumes the credit risk associated with the corporate Borrower and may assume the credit risk associated with an interposed bank or other financial intermediary. The participation interests in which the Fund may invest may not be rated by any NRSRO. See “Risks—Portfolio Level Risks—Senior Loan Participation Risk.”

61

Although senior loans have the most senior position in a Borrower’s capital structure and are often secured by specific collateral, they are typically below investment grade quality and may have below investment grade ratings; these ratings are associated with securities having speculative characteristics. Senior loans rated below investment grade may therefore be regarded as “junk,” despite their senior capital structure position or specific collateral pledged to secure such loans.” The Fund may purchase and retain in its portfolio senior loans where the Borrowers have experienced, or may be perceived to be likely to experience, credit problems, including involvement in or recent emergence from bankruptcy reorganization proceedings or other forms of debt restructuring. Such investments may provide opportunities for enhanced income as well as capital appreciation. At times, in connection with the restructuring of a senior loan either outside of bankruptcy court or in the context of bankruptcy court proceedings, the Fund may determine or be required to accept equity securities or junior debt securities in exchange for all or a portion of a senior loan.

Loan Participations and Assignments

The Fund may purchase participations and/or assignments in commercial loans. Such investments may be secured or unsecured and may pay interest at fixed or floating rates. Loan participations and assignments involve special types of risk, including interest rate risk, liquidity risk and the risks of being a lender.

Loan participations typically represent direct participation, together with other parties, in a loan to a corporate borrower, and generally are offered by banks or other financial institutions or lending syndicates. The Fund may participate in such syndications, or can buy part of a loan, becoming a part lender. When purchasing loan participations, a Fund assumes the credit risk associated with the corporate borrower and may assume the credit risk associated with an interposed bank or other financial intermediary. The loan participations in which the Fund intends to invest may not be rated by any nationally recognized rating service.

Investments in loans through a direct assignment of the financial institution’s interests with respect to the loan may involve additional risks to the Fund. The purchaser of an assignment typically succeeds to all the rights and obligations under the loan agreement with the same rights and obligations as the assigning lender. Assignments may, however, be arranged through private negotiations between potential assignees and potential assignors, and the rights and obligations acquired by the purchaser of an assignment may differ from, and be more limited than, those held by the assigning lender. If a loan is foreclosed, the Fund could become part owner of any collateral, and would bear the costs and liabilities associated with owning and disposing of the collateral. In addition, it is conceivable that under emerging legal theories of lender liability, the Fund could be held liable as co-lender. It is unclear whether loans and other forms of indebtedness offer securities law protections against fraud and misrepresentation. In the absence of definitive regulatory guidance, the Fund relies on Nuveen Asset Management’s research in an attempt to avoid situations where fraud or misrepresentation could adversely affect the Fund.

A loan is often administered by an agent bank acting as agent for all holders. The agent bank administers the terms of the loan, as specified in the loan agreement. In addition, the agent bank is normally responsible for the collection of principal and interest payments from the corporate borrower and the apportionment of these payments to the credit of all institutions which are parties to the loan agreement. Unless, under the terms of the loan, the Fund has direct recourse against the corporate borrower, the Fund may have to rely on the agent bank or other financial intermediary to apply appropriate credit remedies against a corporate borrower. A financial institution’s employment as agent bank might be terminated in the event that it fails to observe a requisite standard of care or becomes insolvent. A successor agent bank would generally be appointed to replace the terminated agent bank, and assets held by the agent bank under the loan agreement should remain available to holders of such indebtedness. However, if assets held by the agent bank for the benefit of the Fund were determined to be subject to the claims of the agent bank’s general creditors, the Fund might incur certain costs and delays in realizing payment on a loan or loan participation and could suffer a loss of principal and/or interest. In situations involving other interposed financial institutions (e.g., an insurance company or governmental agency) similar risks may arise.

62

Second Lien Loans

The Fund may invest in second lien loans and unsecured loans. Such loans are made by public and private corporations and other non-governmental Borrowers for a variety of purposes. As in the case of senior loans, the Fund may purchase interests in second lien loans and unsecured loans through assignments or participations. Second lien loans have similar characteristics as senior loans except that such interests are junior in priority to debt secured with a first lien. Second lien loans are second in priority of payment to one or more senior loans of the related Borrower and are typically secured by a second priority security interest or lien to or on specified collateral securing the Borrower’s obligation under the indebtedness. They typically have similar protections and rights as senior loans. Second lien loans are not (and by their terms cannot become) subordinate in priority of payment to any obligation of the related Borrower other than senior loans of such Borrower. Second lien loans may feature fixed or floating rate interest payments. Because second lien loans are junior to senior loans, they present a greater degree of investment risk but often pay interest at higher rates reflecting this additional risk. In addition, second lien loans of below investment grade quality share many of the risk characteristics of other below investment grade debt instruments.

Unsecured loans generally have lower priority in right of payment compared to holders of secured interests of the Borrower. Unsecured loans are not secured by a security interest or lien to or on specified collateral securing the Borrower’s obligation under the indebtedness. Unsecured loans by their terms may be or may become subordinate in right of payment to other obligations of the Borrower, including senior loans, second lien loans and other interests. Unsecured loans may have fixed or adjustable floating rate interest payments. Because unsecured loans are subordinate to senior loans and other secured debt of the Borrower, they present a greater degree of investment risk but often pay interest at higher rates reflecting this additional risk. Such investments generally are of below investment grade quality. Unsecured loans of below investment grade quality share many of the same risks of other below investment grade debt instruments.

Subordinated Loans

The subordinated loans in which the Fund may invest are typically privately-negotiated investments that rank junior in priority of payment to senior debt, such as senior loans, and are often unsecured. Because subordinated interests may rank lower as to priority of payment than senior loans and second lien loans of the Borrower, they may present a greater degree of investment risk than senior loans and second lien loans but often pay interest at higher rates reflecting this additional risk. Other than their more subordinated status, such investments have many characteristics and risks similar to senior loans and second lien loans discussed above. Subordinated interests of below investment grade quality share risks of other below investment grade debt instruments. Subordinated loans rank senior to common and preferred equity in a Borrower’s capital structure. Subordinated loans may have elements of both debt and equity instruments, offering fixed or adjustable rates of return in the form of interest payments associated with senior debt, while providing lenders an opportunity to participate in the capital appreciation of a Borrower, if any, through an equity interest. This equity interest may take the form of warrants or direct equity investments which will be in conjunction with the subordinated loans. Due to their higher risk profile and often less restrictive covenants as compared to senior loans, subordinated loans generally earn a higher return than secured senior loans. The warrants associated with subordinated loans are typically detachable, which allows lenders the opportunity to receive repayment of their principal on an agreed amortization schedule while retaining their equity interest in the Borrower. Subordinated loans also may include a “put” feature, which permits the holder to sell its equity interest back to the Borrower at a price

determined through an agreed formula.

The Fund may invest in subordinated loans that are primarily unsecured and that provide for relatively high, adjustable rates of interest, providing the Fund with significant current interest income. The subordinated loans in which the Fund may invest may have interest-only payments in the early years, with amortization of principal deferred to the later years of the subordinated loans. In some cases, the Fund may acquire subordinated loans

63

that, by their terms, convert into equity or additional debt instruments or defer payments of interest for the first few years after issuance. Also, in some cases the subordinated loans in which the Fund may invest will be collateralized by a subordinated lien on some or all of the assets of the Borrower.

Preferred Securities

The Fund may invest in all types of preferred securities, including both traditional preferred securities and non-traditional preferred securities. Traditional preferred securities are generally equity securities of the issuer that have priority over the issuer’s common shares as to the payment of dividends (i.e., the issuer cannot pay dividends on its common shares until the dividends on the preferred shares are current) and as to the payout of proceeds of a bankruptcy or other liquidation, but are subordinate to an issuer’s senior debt and junior debt as to both types of payments. Additionally, in a bankruptcy or other liquidation, traditional preferred securities are generally subordinate to an issuer’s trade creditors and other general obligations. Traditional preferred securities may be perpetual or have a term, and typically have a fixed liquidation (or “par”) value.

The term “preferred securities” also includes certain hybrid securities and other types of preferred securities that do not have the traditional features described above. Preferred securities that are hybrid securities often behave similarly to investments in traditional preferred securities and are regarded by market investors as being part of the preferred securities market. Such hybrid securities possess varying combinations of features of both debt and traditional preferred securities and as such they may constitute senior debt, junior debt or preferred shares in an issuer’s capital structure. Thus, they may not be subordinate to a company’s debt securities (as are traditional preferred securities).

Hybrid securities include trust preferred securities. Trust preferred securities are typically issued by corporations, generally in the form of interest-bearing notes with preferred securities characteristics, or by an affiliated business trust of a corporation or other special purpose entity, generally in the form of beneficial interests in subordinated debentures or similarly structured securities. The trust preferred securities market consists of both fixed and floating coupon rate securities that are either perpetual in nature or have stated maturity dates. Trust preferred securities may defer payment of income without triggering an event of default. These securities may have many characteristics of equity due to their subordinated position in an issuer’s capital structure.

Preferred securities may also include certain forms of debt that have many characteristics of preferred shares, and that are regarded by the investment marketplace to be part of the broader preferred securities market. Among these preferred securities are certain exchange-listed debt issues that historically have several attributes, including trading and investment performance characteristics, in common with exchange-listed traditional preferred securities and hybrid securities. Generally, these types of preferred securities are senior debt or junior debt in the capital structure of an issuer.

As a general matter, dividend or interest payments on preferred securities may be cumulative or non-cumulative and may be deferred (in the case of cumulative payments) or skipped (in the case of non-cumulative payments) at the option of the issuer. Generally, preferred security holders have no voting rights with respect to the issuing company, except in some cases voting rights may arise if the issuer fails to pay the preferred share dividends or if a declaration of default occurs and is continuing.

Preferred securities may either trade over-the-counter (“OTC”) or trade on an exchange. Preferred securities can be structured differently for retail and institutional investors, and the Fund may invest in preferred securities of either structure. The retail segment is typified by $25 par value exchange-traded securities and the institutional segment is typified by $1,000 par value OTC securities. Both $25 and $1,000 par value securities are often callable at par value, typically at least five years after their original issuance date.

64

Preferred securities may be issued with either a final maturity date, or as a perpetual structure. In certain instances, a final maturity date may be extended and/or the final payment of principal may be deferred at the issuer’s option for a specified time without any adverse consequence to the issuer.

High Yield Instruments

High yield instruments or “junk bonds” that are rated below investment grade involve a greater degree of risk (in particular, a greater risk of default) than, and special risks in addition to, the risks associated with investment grade instruments. Under rating agency guidelines, medium- and lower-rated instruments and comparable unrated instruments will likely have some quality and protective characteristics that are outweighed by large uncertainties or major risk exposures to adverse conditions. Medium- and lower-rated instruments may have poor prospects of ever attaining any real investment standing, may have a current identifiable vulnerability to default or be in default, may be unlikely to have the capacity to pay interest or dividends and repay liquidation preference or principal when due in the event of adverse business, financial or economic conditions, and/or may be likely to be in default or not current in the payment of interest, dividends, liquidation preference or principal. Such instruments are considered speculative with respect to the issuer’s capacity to pay interest or dividends and repay liquidation preference or principal in accordance with the terms of the obligation. Accordingly, it is possible that these types of factors could reduce the value of securities held by the Fund with a commensurate effect on the value of the Common Shares. High yield instruments involve substantial risk of loss and are susceptible to default or decline in market value due to real or perceived adverse economic and business developments or competitive industry conditions, as compared to higher-rated instruments. These instruments generally provide higher income than investment grade instruments in an effort to compensate investors for their higher risk of default, which is the issuer’s failure to make required interest, dividends, liquidation preference or principal payments on the securities. High yield instruments issuers include small or relatively new companies lacking the history or capital to merit investment-grade status, former blue chip companies downgraded because of financial problems, companies electing to borrow heavily to finance or avoid a takeover or buyout, and firms with heavy debt loads.

The secondary markets for these instruments are generally not as liquid as the secondary markets for higher rated instruments. The secondary markets for high yield instruments are concentrated in relatively few market makers and the participants in the market are mostly institutional investors, including insurance companies, banks, other financial institutions and mutual funds. In addition, the trading volume for high yield instruments is generally lower than that for higher-rated instruments, and the secondary markets could contract under adverse market or economic conditions independent of any specific adverse changes in the condition of a particular issuer. These factors may have an adverse effect on the ability of the Fund to dispose of particular portfolio investments, may adversely affect the Fund’s NAV per share and may limit the ability of the Fund to obtain accurate market quotations for purposes of valuing securities and calculating NAV. If the Fund is not able to obtain precise or accurate market quotations for a particular instrument, it will become more difficult to value the Fund’s portfolio investments, and a greater degree of judgment may be necessary in making such valuations. Less liquid secondary markets may also affect the ability of the Fund to sell instruments at their fair value. If the secondary markets for high yield instruments contract due to adverse economic conditions or for other reasons, certain securities in the Fund’s portfolio may become illiquid and the proportion of the Fund’s assets invested in illiquid instruments may significantly increase.

Prices for high yield instruments may be affected by legislative and regulatory developments. These laws could adversely affect the Fund’s NAV and investment practices, the secondary market for high yield instruments, the financial condition of issuers of these securities and the value of outstanding high yield instruments. See “Risks—Portfolio Level Risks—Below Investment Grade Risk.”

High yield instruments rated in the lower rating categories (Caa1 or lower by Moody’s, CCC+ or lower by S&P or Fitch, or comparably rated by another NRSRO) are subject to very high credit risk. The Fund may not invest in an issuer who is in default on its obligations to pay principal or interest thereon when due or that is in bankruptcy or insolvency proceedings.

65

Regulation S Securities

The Fund may seek to provide exposure to Regulation S securities that are not freely tradable in the U.S. by investing in the Subsidiary. The Fund may also invest directly in Regulation S securities that are freely tradable in the U.S. Regulation S securities are debt or equity securities of U.S. and foreign issuers offered through private offerings exempt from registration with the SEC pursuant to Regulation S of the 1933 Act. Offerings of Regulation S securities may be conducted outside of the United States, and Regulation S securities may be relatively less liquid as a result of legal or contractual restrictions on resale. Although Regulation S securities may be resold in privately negotiated transactions, the price realized from these sales could be less than the price originally paid by the Fund. Further, companies whose securities are not publicly traded may not be subject to the disclosure of other investor protection requirements that would be applicable is their securities were publicly traded. Accordingly, Regulation S securities may involve a high degree of business and financial risk and may result in substantial. See “Risks—Fund Level Risks—Subsidiary Risk” and “—Portfolio Level Risks—Regulation S Securities Risk.”

Illiquid Investments

The Fund may invest in illiquid investments (i.e., investments that are not readily marketable), including, but not limited to, restricted investments (investments the disposition of which is restricted under the federal securities laws), securities that may be resold only pursuant to Rule 144A under the 1933 Act that are deemed to be illiquid, and certain repurchase agreements.

Restricted investments may be sold only in privately negotiated transactions or in a public offering with respect to which a registration statement is in effect under the 1933 Act. Where registration is required, the Fund may be obligated to pay all or part of the registration expenses and a considerable period may elapse between the time of the decision to sell and the time the Fund may be permitted to sell a investment 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. To the extent that the Board of Trustees or its delegatee determines that the price of any illiquid investment provided by the pricing service is inappropriate, such investment will be priced at a fair value as determined in good faith by the Board or its delegatee.

Derivatives

The Fund may use certain derivative instruments in pursuit of its investment objective. Such instruments include financial futures contracts, forward contracts, swap contracts (including interest rate, total return and credit default swaps), options on financial futures, options on swap contracts or other derivative instruments. The credit default swaps in which the Fund may invest include CDX and single-name CDS. A CDX is a portfolio of credit default swaps with similar characteristics, such as credit default swaps on high-yield bonds. Certain CDX instruments are subject to mandatory central clearing and exchange trading, which may reduce counterparty credit risk and increase liquidity compared to other credit default swaps or CDX transactions. Unlike other types of credit default swaps, single-name CDS do not have the benefit of diversification across many issuers. Interest rate swaps involve the exchange by the Fund with a counterparty of their respective commitments to pay or receive interest, such as an exchange of fixed-rate payments for floating rate payments. The Fund will usually enter into interest rate swaps on a net basis; that is, the two payment streams will be netted out in a cash settlement on the payment date or dates specified in the instrument, with the Fund receiving or paying, as the case may be, only the net amount of the two payments. See “Portfolio Composition and Other Information—Hedging Strategies and Other Uses of Derivatives” in the SAI and “Asset Segregation” below.

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

66

Nuveen Fund Advisors and Nuveen Asset Management may use derivative instruments to seek to enhance return, to attempt to hedge some of the risk of the Fund’s investments in fixed-income investments, to attempt to manage the effective maturity or duration of investments in the Fund’s portfolio or as a substitute for a position in the underlying asset. These types of strategies may generate taxable income. The Fund will value derivative instruments at market/fair value for purposes of calculating compliance with the Fund’s 80% investment policy in fixed-income investments.

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

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

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

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

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

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

67

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

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. Credit default swaps may require initial premium (discount) payments as well as periodic payments (receipts) related to the interest leg of the swap or to the default of a reference obligation. 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), such as a U.S. or foreign corporation, of the underlying referenced obligation(s). If no default occurs, the protection seller would keep the stream of payments and would have no further obligation to the Fund. Thus, the cost to the Fund would be the premium paid with respect to the agreement. If a credit event occurs, however, the Fund may elect to receive the full notional value of the swap in exchange for an equal face amount of deliverable obligations of the reference entity that may have little or no value. The Fund bears the risk that the protection seller may fail to satisfy its payment obligations. If the Fund sells or writes credit default swaps, the Fund will segregate the full notional amount of the payment obligation under the credit default swap that must be paid upon the occurrence of a credit event. See “—Asset Segregation” below.

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

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, couponbearing 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 and the Fund may have to segregate additional liquid assets in accordance with applicable SEC requirements. See “—Asset Segregation” below.

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.

Options on Currencies.    The Fund may purchase put and call options on foreign currencies. A foreign currency option provides the option buyer with the right to buy or sell a stated amount of foreign currency at the exercise price at a specified date or during the option period. A call option gives its owner the right, but not the obligation, to buy the currency, while a put option gives its owner the right, but not the obligation, to sell the currency. The option seller (writer) is obligated to fulfill the terms of the option sold if it is exercised. However, either seller or buyer may close its position during the option period in the secondary market for such options at any time prior to expiration.

A foreign currency call option rises in value if the underlying currency appreciates. Conversely, a foreign currency put option rises in value if the underlying currency depreciates. While purchasing a foreign currency option may protect the Fund against an adverse movement in the value of a foreign currency, it would limit the

69

gain which might result from a favorable movement in the value of the currency. For example, if the Fund were holding securities denominated in an appreciating foreign currency and had purchased a foreign currency put to hedge against a decline in the value of the currency, it would not have to exercise its put. In such an event, however, the amount of the Fund’s gain would be offset in part by the premium paid for the option. Similarly, if the Fund entered into a contract to purchase a security denominated in a foreign currency and purchased a foreign currency call to hedge against a rise in the value of the currency between the date of purchase and the settlement date, the Fund would not need to exercise its call if the currency instead depreciated in value. In such a case, the Fund could acquire the amount of foreign currency needed for settlement in the spot market at a lower price than the exercise price of the option.

Forward Currency Contracts and other Foreign Currency Transactions.    The Fund may enter into forward currency contracts. A forward currency contract involves an obligation to purchase or sell a specific currency at a future date, which may be any fixed number of days from the date of the contract agreed upon by the parties, at a price set at the time of the contract. These contracts are traded directly between currency traders (usually large commercial banks) and their customers. Unlike futures contracts, which are standardized contracts, forward contracts can be specifically drawn to meet the needs of the parties that enter into them. The parties to a forward currency contract may agree to offset or terminate the contract before its maturity, or may hold the contract to maturity and complete the contemplated exchange. Because forward contracts are not traded on an exchange, the Fund is subject to the credit and performance risk of the counterparties to such contracts.

The following, among others, are types of currency management strategies involving forward contracts that may be used by the Fund. The Fund also may use currency futures contracts and options thereon, put and call options on foreign currencies and currency swaps for the same purposes.

Position Hedges.    The Fund could also use forward contracts to lock in the U.S. dollar value of portfolio positions. This is known as a “position hedge.” When the Fund believes that a foreign currency might suffer a substantial decline against the U.S. dollar, it could enter into a forward contract to sell an amount of that foreign currency approximating the value of some or all of the Fund’s portfolio investments denominated in that foreign currency. When the Fund believes that the U.S. dollar might suffer a substantial decline against a foreign currency, it could enter into a forward contract to buy that foreign currency for a fixed dollar amount. Alternatively, the Fund could enter into a forward contract to sell a different foreign currency for a fixed U.S. dollar amount if the Fund’s portfolio managers believe that the U.S. dollar value of that foreign currency will fall whenever there is a decline in the U.S. dollar value of the currency in which portfolio investments of the Fund are denominated. This is referred to as a “cross hedge.”

Shifting Currency Exposure.    The Fund may also enter into forward contracts to shift its investment exposure from one currency into another. This may include shifting exposure from U.S. dollars to foreign currency or from one foreign currency to another foreign currency. This strategy tends to limit exposure to the currency sold, and increase exposure to the currency that is purchased, much as if the Fund had sold an investment denominated in one currency and purchased an equivalent investment denominated in another currency.

Other Investment Companies

The Fund may invest in securities of other investment companies such as, among others, ETFs, subject to limitations imposed by the 1940 Act, rules promulgated thereunder and exemptive orders issued by the SEC. The Fund generally expects that it may invest in other investment companies during periods when it has large amounts of uninvested cash, such as during periods when there is a shortage of attractive securities of the types in which the Fund may invest directly available in the market. As an investor in an investment company, the Fund will bear its ratable share of that investment company’s expenses, and would remain subject to payment of the Fund’s advisory and administrative 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.

70

Nuveen Asset Management will take expenses into account when evaluating the investment merits of an investment in the investment company relative to available securities of the types in which the Fund may invest directly. In addition, the securities of other investment companies may be leveraged and therefore will be subject to leverage risks.

Asset Segregation

As a closed-end investment company registered with the SEC, the Fund is subject to the federal securities laws, including the 1940 Act, the rules thereunder, and various interpretive positions of the SEC and its staff. Under current laws, rules and positions, the Fund must maintain liquid assets (often referred to as “asset segregation”), or engage in other SEC staff-approved measures, to “cover” open positions with respect to certain kinds of derivative instruments and financial agreements (such as reverse repurchase agreements).

Generally, the Fund will maintain an amount of liquid assets with its custodian in an amount at least equal to the current amount of its obligations under derivative instruments and financial agreements, in accordance with SEC guidance. However, the Fund also may “cover” certain obligations by other means such as through ownership of the underlying investment or financial instrument. The Fund also may enter into offsetting transactions with respect to certain instruments consistent with existing SEC staff guidance so that its combined position, coupled with any liquid assets maintained by its custodian, equals its net outstanding obligation in related derivatives or financial agreements.

The SEC recently adopted new Rule 18f-4 under the 1940 Act, which imposes limits on the amount of derivatives a fund can enter into and replaces the asset segregation framework previously used by funds to comply with Section 18 of the 1940 Act, among other requirements. The Fund will comply with the new rule’s requirements on or before the SEC’s compliance date in 2022.

The Fund reserves the right to modify its policies in the future to comply with any changes in the positions from time to time articulated by the SEC or its staff.

Temporary Defensive Investments

During temporary defensive periods, the period in which the net proceeds of this offering of Common Shares are first being invested (the “invest-up period”), the “wind-up” period during which the Fund is transitioning its portfolio as the Termination Date approaches or the period in which the Fund’s assets are being liquidated in anticipation of the Fund’s termination, the Fund may deviate from its investment policies and objective. During such periods, the Fund may invest up to 100% of its Managed Assets in short-term investments, including high quality, short-term securities or may invest in short-, intermediate-, or long-term U.S. Treasury securities. During the invest-up period, the Fund may also purchase securities issued by ETFs that invest primarily in fixed-income investments of the types in which the Fund may invest directly. Any such investments in ETFs will be in compliance with the limitations imposed by the 1940 Act, the rules promulgated thereunder, or pursuant to any exemptive relief obtained thereunder. There can be no assurance that such techniques will be successful. Accordingly, during such periods, the Fund may not achieve its investment objective.

Initial Portfolio Composition

[To be provided by amendment.]

Portfolio Turnover

It is not the Fund’s policy to engage in transactions with the objective of seeking profits from short-term trading. However, the Fund may engage in active and frequent trading when Nuveen Fund Advisors or Nuveen

71

Asset Management believes such trading is, in light of prevailing economic and market circumstances, in the best interests of the Fund’s shareholders. Although the Fund cannot predict its annual portfolio turnover rate, it is generally not expected to exceed [    ]% under normal circumstances. Frequent trading also increases transaction costs, which could detract from the Fund’s performance, and may result in the realization of net short-term capital gains by the Fund which, when distributed to Common Shareholders, will be treated as ordinary income. See “Tax Matters.”

LEVERAGE

The Fund anticipates using leverage to pursue its investment objective. The Fund may use leverage to the extent permitted under the 1940 Act. The Fund may source leverage initially and throughout the life of the Fund through a number of methods including through borrowings, issuing Preferred Shares, the issuance of debt securities, entering into reverse repurchase agreements (effectively a borrowing), and investing 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. In addition, the Fund may use derivatives that may have the economic effect of leverage. The sources of leverage will vary depending on market conditions. See “Leverage,” “ Risks—Portfolio Level Risks—Inverse Floating Rate Securities Risk,” and “Portfolio Composition and Other Information—Derivatives.” The Fund anticipates using such leverage in an aggregate amount equal to approximately             % of the Fund’s Managed Assets, if current market conditions persist.

The Fund may use derivatives, such as interest rate swaps with varying terms, in order to hedge duration risk or 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 market 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 be greater (and thereby reduce distributions to Common Shareholders) than if the Fund had not entered into the interest rate swap(s). See “Portfolio Composition and Other Information—Derivatives.”

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

In pursuit of its investment objective, the Fund has the ability to actively and dynamically reduce or increase the amount and type of leverage based upon changes in market conditions, composition of the Fund’s holdings and remaining time until the Fund’s Termination Date. The Fund’s leverage ratio will vary from time to time based upon such changes in the amount of leverage used and variations in the value of the Fund’s holdings. So long as the net income received from the Fund’s investments purchased with leverage proceeds exceeds the then current expense of any leverage, the investment of the proceeds of leverage will generate more net income than if the Fund had not leveraged itself. Under these circumstances, the excess net income will be available to pay higher distributions to Common Shareholders. However, if the net income received from the Fund’s portfolio investments purchased with the proceeds of leverage is less than the current expense of any leverage, the Fund may be required to utilize other Fund assets to make interest or dividend payments on its leveraging instruments which may result in a decline in Common Share NAV and reduced net investment income available for distribution to Common Shareholders.

72

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, it is anticipated that the Fund’s Managed Assets will be greater than its net assets. Nuveen Fund Advisors and Nuveen Asset Management will be responsible for using leverage to pursue the Fund’s investment objective. Nuveen Fund Advisors and Nuveen Asset Management will base their decision regarding whether and how much leverage to use for the Fund, and the terms of that leverage, on their 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 and Nuveen Asset Management may have a conflict of interest in determining whether to use or increase leverage. Nuveen Fund Advisors and Nuveen Asset Management will seek to manage that potential conflict by using leverage only when they determine that it would be in the best interests of the Fund and its Common Shareholders, and by periodically reviewing with the Board of Trustees the Fund’s performance and the Fund’s degree of overall use of leverage and the impact of the use of leverage on that performance.

The Fund may issue “senior securities” as defined under the 1940 Act. 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” 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.

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) and debt securities. “Senior securities representing indebtedness” also include other derivative investments or transactions, such as reverse repurchase agreements, to the extent the Fund has not fully covered, segregated or earmarked cash or liquid assets in accordance with the 1940 Act, the rules thereunder, and applicable positions of the SEC and its staff. With respect to any such senior securities representing debt, 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 issued by the Fund.

If the Fund issues senior securities and the asset coverage with respect to such senior securities 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 or other portfolio composition limits by its lenders, debt or preferred securities purchasers, rating agencies that may rate the debt or preferred securities, or reverse repurchase counterparties. Such limitations may be more stringent than those imposed by the 1940 Act and may impact whether the Fund is able to maintain its

73

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 objective and policies.

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 “Risks—Fund Level Risks—Leverage Risk.” 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.

Effects of Leverage

Assuming the utilization of leverage in an aggregate amount of approximately         % of the Fund’s Managed Assets, at an interest and/or dividend rate of         % payable on such leverage, the income generated by the Fund’s portfolio (net of non-leverage expenses) must exceed         % in order to cover such interest and/or dividend payments and other expenses. Of course, these numbers are merely estimates, used for illustration. Actual interest and/or dividend rates may vary frequently and may be significantly higher or lower than the rate estimated above.

The following table is furnished in response to requirements of the SEC. It is designed to illustrate the effect of leverage on Common Share total return, assuming investment portfolio total returns (comprised of income and changes in the value of investments held in the Fund’s portfolio) of –10%, –5%, 0%, 5% and 10%. These assumed investment portfolio returns are hypothetical figures and are not necessarily indicative of the investment portfolio returns experienced or expected to be experienced by the Fund. Actual returns may be greater or less than those shown below. See “Risks.” The table further reflects the use of leverage representing         % of the Fund’s Managed Assets, net of expenses, and the Fund’s currently projected annual interest rate and/or dividend on its leverage of         %.

Common Share Total Return is composed of two elements: the Common Share dividends paid by the Fund (the amount of which is largely determined by the net investment income of the Fund after paying interest and/or dividends on its leverage) and gains or losses on the value of the investments the Fund owns. The table required by SEC rules above assumes that the Fund is more likely to suffer capital losses than to enjoy capital appreciation. For example, to assume a total return of 0% the Fund must assume that the interest it receives on its portfolio investments is entirely offset by losses in the value of those investments.

74

RISKS

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

Portfolio Level Risks

Impact Criteria and ESG Investing Criteria Risk

Because the Fund’s Impact Criteria and/or ESG investment criteria may exclude investments of certain issuers for non-financial reasons, the Fund may forgo some market opportunities available to funds that do not use these criteria. This may cause the Fund to underperform the market as a whole or other funds that do not use an Impact Criteria or ESG investment strategy. In addition, there is a risk that the companies identified by the Fund’s Impact Criteria or ESG investment criteria do not operate as expected when addressing social and environmental impact and ESG issues. A company’s social and environmental impact and ESG performance or Nuveen Asset Management’s assessment of a company’s social and environmental impact and ESG performance could vary over time, which could cause the Fund to be temporarily invested in companies that do not comply with the Fund’s approach towards considering Impact Criteria or ESG investment criteria. There are significant differences in interpretations of what it means for a company to have positive Impact Criteria or ESG investment criteria. While Nuveen Asset Management believes its evaluation of Impact Criteria and/or ESG investment criteria is reasonable, the portfolio decisions it makes may differ with other investors’ or advisers’ views. In making investment decisions, Nuveen Asset Management relies on information and data that could be incomplete or erroneous, which could cause Nuveen Asset Management to incorrectly assess a company’s Impact Criteria and/or ESG investment criteria. The third-party data providers may differ in the data they provide for a given investment or between industries, or may only take into account one of many ESG-related components of a company. Furthermore, data availability and reporting with respect to Impact Criteria or the ESG investment criteria may not always be available or may become unreliable.

Active Management Risk

The Fund is actively managed and depends heavily on Nuveen Asset Management’s judgment about markets, interest rates or the attractiveness, relative values, liquidity, or potential appreciation of particular investments made for the Fund’s portfolio. The Fund could experience losses if these judgments prove to be incorrect. Additionally, legislative, regulatory, or tax developments may adversely affect management of the Fund and, therefore, the ability of the Fund to achieve its investment objective.

Debt Securities Risk

Issuers of debt instruments in which the Fund may invest may default on their obligations to pay principal or interest when due. This non-payment would result in a reduction of income to the Fund, a reduction in the value of a debt instrument experiencing non-payment and, potentially, a decrease in the NAV of the Fund. There can be no assurance that liquidation of collateral would satisfy the issuer’s obligation in the event of non-payment of scheduled interest or principal or that such collateral could be readily liquidated. In the event of bankruptcy of an issuer, the Fund could experience delays or limitations with respect to its ability to realize the benefits of any collateral securing a security. To the extent that the credit rating assigned to a security in the Fund’s portfolio is downgraded, the market price and liquidity of such security may be adversely affected. When market interest rates rise, the market value of such instruments generally will fall.

75

Additionally, the Fund may be exposed to certain debt securities risks through its sukuk investments. Most sukuk do not provide investors with bona fide legal ownership of the underlying assets, and the periodic and final payments to sukuk investors are not generally linked to the value of the underlying assets. As a result, most sukuk are considered unsecured obligations whose risks and returns are similar to those of conventional debt instruments. Investors typically have no direct recourse to the underlying assets and do not have a secured claim against the obligor. In addition, investors’ ability to pursue and enforce actions with respect to these payment obligations or to otherwise enforce the terms of the sukuk, restructure the sukuk, obtain a judgment in a court of competent jurisdiction, and/or attach assets of the obligor may be limited. The structural complexity of sukuk and the immaturity of the sukuk market increase the potential risks of investing in sukuk, including operational, legal, and investment risks. Sukuk can be less liquid than other types of investments and it may be difficult at times to invest in or dispose of sukuk. In addition, evolving interpretations of Sharia law by courts or Islamic scholars on sukuk structures and sukuk transferability, or a determination subsequent to the issuance of the sukuk by some Islamic scholars that certain sukuk do not comply with Sharia law and its investment principles, could have a dramatic adverse effect on the price and liquidity of a particular sukuk or the sukuk market in general.

CMBS and MBS Risk

CMBS and MBS, including collateralized debt obligations and collateralized mortgage obligations, differ from conventional debt securities because principal is paid back over the life of the security rather than at maturity. CMBS and MBS are subject to prepayment or call risk, which is the risk that a borrower’s payments may be received earlier than expected due to changes in prepayment rates on underlying loans. Faster prepayments often happen when interest rates are falling. As a result, the Fund may reinvest these early payments at lower interest rates, thereby reducing the Fund’s income. CMBS and MBS also are subject to extension risk. An unexpected rise in interest rates could reduce the rate of prepayments and extend the life of the CMBS and MBS, causing the price of the CMBS and MBS and the Fund’s share price to fall and would make the CMBS and MBS more sensitive to interest rate changes. An unexpectedly high rate of defaults on the mortgages held by a mortgage pool will adversely affect the value of CMBS and MBS and will result in losses to the Fund. Privately issued mortgage-related securities are not subject to the same underwriting requirements for the underlying mortgages that are applicable to those mortgage-related securities that have government or government-sponsored entity guarantee. As a result, the mortgage loans underlying privately issued mortgage-related securities may, and frequently do, have less favorable collateral, credit risk or other underwriting characteristics than government or government-sponsored mortgage-related securities and have wider variances in a number of terms including interest rate, term, size, purpose and borrower characteristics.

Asset-Backed Securities Risk

ABS involve certain risks in addition to those presented by MBS. There is the possibility that recoveries on the underlying collateral may not, in some cases, be available to support payments on these securities. Relative to MBS, ABS may provide the Fund with a less effective security interest in the underlying collateral and are more dependent on the borrower’s ability to pay. If many borrowers on the underlying loans default, losses could exceed the credit enhancement level and result in losses to investors in an ABS transaction. Finally, ABS have structure risk due to a unique characteristic known as early amortization, or early payout, risk. Built into the structure of most ABS are triggers for early payout, designed to protect investors from losses. These triggers are unique to each transaction and can include a significant rise in defaults on the underlying loans, a sharp drop in the credit enhancement level or the bankruptcy of the originator. Once early amortization begins, all incoming loan payments (after expenses are paid) are used to pay investors as quickly as possible based upon a predetermined priority of payment. As a result, proceeds that would otherwise be distributed to holders of a junior tranche may be diverted to pay down more senior tranches.

The collateral underlying ABS may constitute assets related to a wide range of industries and sectors, such as credit card and automobile receivables. Credit card receivables are generally unsecured and the debtors are entitled to the protection of a number of state and federal consumer credit laws, many of which give debtors the

76

right to set off certain amounts owed on the credit cards, thereby reducing the balance due. The Credit CARD Act of 2009 imposes new regulations on the ability of credit card issuers to adjust the interest rates and exercise various other rights with respect to indebtedness extended through credit cards. The Fund and Nuveen Asset Management cannot predict what effect, if any, such regulations might have on the market for ABS and such regulations may adversely affect the value of ABS owned by the Fund. Most issuers of automobile receivables permit the servicers to retain possession of the underlying obligations. If the servicer were to sell these obligations to another party, there is a risk that the purchaser would acquire an interest superior to that of the holders of the related automobile receivables. In addition, because of the large number of vehicles involved in a typical issuance and technical requirements under state laws, the trustee for the holders of the automobile receivables may not have an effective security interest in all of the obligations backing such receivables. If the economy of the United States deteriorates, defaults on securities backed by credit card, automobile and other receivables may increase, which may adversely affect the value of any ABS owned by Fund. There is the possibility that recoveries on the underlying collateral may not, in some cases, be available to support payments on these securities. In recent years, certain automobile manufacturers have been granted access to emergency loans from the U.S. Government and have experienced bankruptcy. As a result of these events, the value of securities backed by receivables from the sale or lease of automobiles may be adversely affected.

Some ABS, particularly home equity loan transactions, are subject to interest rate risk and prepayment risk. A change in interest rates can affect the pace of payments on the underlying loans, which in turn, affects total return on the securities.

Municipal Securities Market Risk

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

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

The outbreak of the novel coronavirus, known as COVID-19, in December 2019, and the resulting pandemic, has adversely impacted global commercial activity and has contributed to significant volatility in certain financial markets, including the municipal bond market. See “—Other Risks—Global Economic Risk”.

77

Due to the COVID-19 pandemic, the risks of the municipal securities market have been magnified. These risks have had, and will continue to have, a material adverse impact on local economies and therefore on the governments in those localities. These risks may also adversely affect several sectors of the municipal bond market, such as retirement facilities, transportation facilities such as airports, hospitals and colleges, among many others. All this has adversely affected the municipal securities market, and may continue to do so for an extended period.

Foreign/Emerging Markets Issuer Risk

Investments in foreign issuers involve special risks not presented by investments in U.S. issuers, including the following: (i) less publicly available information about foreign issuers or markets due to less rigorous disclosure or accounting standards or regulatory practices; (ii) many foreign markets are smaller, less liquid and more volatile; (iii) potential adverse effects of fluctuations in currency exchange rates or controls on the value of the Fund’s investments; (iv) the economies of foreign countries may grow at slower rates than expected or may experience a downturn or recession; (v) the impact of economic, political, social or diplomatic events; (vi) possible seizure of a company’s assets; (vii) restrictions imposed by foreign countries limiting the ability of foreign issuers to make payments of principal and/or interest due to blockages of foreign currency exchanges or otherwise and (viii) withholding and other foreign taxes may decrease the Fund’s return.

The Fund will invest in emerging market debt securities. Risks of investing in investments of emerging markets issuers include: smaller market capitalization of securities markets, which may suffer periods of relative illiquidity; significant price volatility; restrictions on foreign investment; and possible restrictions on repatriation of investment income and capital. In addition, foreign investors may be required to register the proceeds of sales; and future economic or political crises could lead to price controls, forced mergers, expropriation or confiscatory taxation, seizure, nationalization, or creation of government monopolies. Inflation and rapid fluctuations in inflation rates have had, and may continue to have, negative effects on the economies and securities markets of certain emerging market countries. Certain emerging markets also may face other significant internal or external risks, including a heightened risk of war, and ethnic, religious and racial conflicts. In addition, governments in many emerging market countries participate to a significant degree in their economies and securities markets, which may impair investment and economic growth, and which may in turn diminish the value of the companies in those markets.

In addition, the Fund may invest in “frontier market” debt securities, which the Fund considers to be a sub-set of emerging market debt securities. The Fund considers a “frontier market” to be a market that is generally smaller and less mature than larger emerging markets, but is nonetheless accessible to foreign investment through sovereign and/or corporate bonds issued in hard currency like the U.S. dollar. Frontier market economies and capital markets are typically at an earlier stage of development and institutions and macro-economic policy formulation is also less mature in comparison to larger emerging market countries. While frontier markets have much in common, there are also significant differences when it comes to their political and policy environments, natural resource base, and economic structures and cycles. Participants in the fixed-income markets, unlike participants in the equity markets, generally consider frontier economies to be a sub-category of emerging economies. Countries frequently deemed frontier markets are included in common emerging market debt benchmarks such as the EMBI, where such markets currently account for over half the countries in the index and nearly a third of its total market weighted capitalization. Furthermore, inclusion criteria remains the same for a frontier versus non-frontier market in the broad EMBI-GD and is based on the same liquidity and minimum issuance criteria as any other emerging market country. All things considered, risks are magnified in frontier markets which are the result of: potential for extreme price volatility and illiquidity in frontier markets; government ownership or control of parts of private sector and of certain companies; trade barriers, exchange controls, managed adjustments in relative currency values and other protectionist measures imposed or negotiated by frontier market countries or their trading partners; and the relatively new and unsettled securities laws in many frontier market countries.

78

Additionally, the Fund may be exposed to certain debt securities risks through its sukuk investments. Most sukuk do not provide investors with bona fide legal ownership of the underlying assets, and the periodic and final payments to sukuk investors are not generally linked to the value of the underlying assets. As a result, most sukuk are considered unsecured obligations whose risks and returns are similar to those of conventional debt instruments. Investors typically have no direct recourse to the underlying assets and do not have a secured claim against the obligor. In addition, investors’ ability to pursue and enforce actions with respect to these payment obligations or to otherwise enforce the terms of the sukuk, restructure the sukuk, obtain a judgment in a court of competent jurisdiction, and/or attach assets of the obligor may be limited.

The structural complexity of sukuk and the immaturity of the sukuk market increase the potential risks of investing in sukuk, including operational, legal, and investment risks. Sukuk can be less liquid than other types of investments and it may be difficult at times to invest in or dispose of sukuk. In addition, evolving interpretations of Sharia law by courts or Islamic scholars on sukuk structures and sukuk transferability, or a determination subsequent to the issuance of the sukuk by some Islamic scholars that certain sukuk do not comply with Sharia law and its investment principles, could have a dramatic adverse effect on the price and liquidity of a particular sukuk or the sukuk market in general.

Investments in foreign issuers involve special risks not presented by investments in U.S. issuers, including the following: less publicly available information about foreign issuers or markets due to less rigorous disclosure or accounting standards or regulatory practices; many foreign markets are smaller, less liquid and more volatile; potential adverse effects of fluctuations in currency exchange rates or controls on the value of the Fund’s investments; the economies of foreign countries may grow at slower rates than expected or may experience a downturn or recession; the impact of economic, political, social or diplomatic events; possible seizure of a company’s assets; and withholding and other foreign taxes may decrease the Fund’s return. These risks are more pronounced to the extent that the Fund invests a significant amount of its assets in companies located in one region and to the extent that the Fund invests in issuers in emerging markets. In addition, economic, political and social developments may significantly disrupt the financial markets or interfere with the Fund’s ability to enforce its rights against foreign sovereign issuers.

The Fund’s income from foreign issuers may be subject to foreign withholding taxes. In some countries, the Fund also may be subject to taxes on trading profits and, on certain securities transactions, transfer or stamp duties tax. To the extent foreign income taxes are paid by the Fund, U.S. shareholders may be entitled to a credit or deduction for U.S. federal income tax purposes.

Sovereign Government and Supranational Debt Risk

Investments in sovereign debt, including supranational debt, involve special risks. Foreign governmental issuers of debt or the governmental authorities that control the repayment of the debt may be unable or unwilling to repay principal or pay interest when due. In the event of default, there may be limited or no legal recourse in that, generally, remedies for defaults must be pursued in the courts of the defaulting party. Political conditions, especially a sovereign entity’s willingness to meet the terms of its debt obligations, are of considerable significance. The ability of a foreign sovereign issuer, especially an emerging market country, to make timely payments on its debt obligations will also be strongly influenced by the sovereign issuer’s balance of payments, including export performance, its access to international credit facilities and investments, fluctuations of interest rates and the extent of its foreign reserves. A country whose exports are concentrated in a few commodities or whose economy depends on certain strategic imports could be vulnerable to fluctuations in international prices of these commodities or imports. If a sovereign issuer cannot generate sufficient earnings from foreign trade to service its external debt, it may need to depend on continuing loans and aid from foreign governments, commercial banks, and multinational organizations. The cost of servicing external debt will also generally be adversely affected by rising international interest rates, as many external debt obligations bear interest at rates which are adjusted based upon international interest rates. Foreign investment in certain sovereign debt is restricted or controlled to varying degrees, including requiring governmental approval for the repatriation of

79

income, capital or proceeds of sales by foreign investors. There are no bankruptcy proceedings similar to those in the U.S. by which defaulted sovereign debt may be collected.

U.S. Government Securities Risk

U.S. government securities are guaranteed only as to the timely payment of interest and the payment of principal when held to maturity. Accordingly, the current market values for these securities will fluctuate with changes in interest rates. Securities issued or guaranteed by U.S. government agencies and instrumentalities are supported by varying degrees of credit but generally are not backed by the full faith and credit of the U.S. government. No assurance can be given that the U.S. government will provide financial support to its agencies and instrumentalities if it is not obligated by law to do so.

Below Investment Grade Risk

Instruments of below investment grade quality are regarded as having predominately speculative characteristics with respect to the issuer’s capacity to pay interest, dividends and repay principal, and are commonly referred to as “high yield” or “junk,” which implies higher price volatility and default risk than investment grade instruments of comparable terms and duration. Issuers of lower grade instruments may be highly leveraged and may not have available to them more traditional methods of financing. The prices of these lower grade instruments are typically more sensitive to negative developments, such as a decline in the issuer’s revenues or a general economic downturn, than are the prices of higher grade instruments.

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

The secondary market for lower grade instruments may not be as liquid as the secondary market for more highly rated instruments, a factor which may have an adverse effect on the Fund’s ability to dispose of a particular instrument. There are fewer dealers in the market for lower grade instruments than for investment grade obligations. The prices quoted by different dealers for lower grade instruments may vary significantly and the spread between the bid and ask price for such instruments is generally much larger than for higher quality instruments. Under adverse market or economic conditions, the secondary market for lower grade instruments could contract further, independent of any specific adverse changes in the condition of a particular issuer, and these instruments may become illiquid. As a result, the Fund could find it more difficult to sell these instruments or may be able to sell the instruments only at prices lower than if such instruments were widely traded. Prices realized upon the sale of such lower rated or unrated instruments, under these circumstances, may be less than the prices used in calculating the Fund’s NAV.

For these reasons, an investment in the Fund, compared with a portfolio consisting solely of investment grade instruments, may experience the following:

In the event that the Fund disposes of a portfolio investment subsequent to its being downgraded, the Fund may experience a greater loss than if such investment had been sold prior to such downgrade.

80

Foreign Currency Risk 

Because the Fund may invest in investments denominated or quoted in currencies other than the U.S. dollar, changes in foreign currency exchange rates may affect the value of investments held by the Fund and the unrealized appreciation or depreciation of investments. Currencies of certain countries may be volatile and therefore may affect the value of investments denominated in such currencies, which means that the Fund’s NAV could decline as a result of changes in the exchange rates between foreign currencies and the U.S. dollar. In addition, certain countries, particularly emerging market countries, may impose foreign currency exchange controls or other restrictions on the transferability, repatriation or convertibility of currency.

Loan Risk

The lack of an active trading market for certain loans may impair the ability of the Fund to realize full value in the event of the need to sell a loan and may make it difficult to value such loans. Portfolio transactions in loans may settle in as short as seven days but typically can take up to two or three weeks, and in some cases much longer. As a result of these extended settlement periods, the Fund may incur losses if it is required to sell other investments or temporarily borrow to meet its cash needs, including satisfying redemption requests. The risks associated with unsecured loans, which are not backed by a security interest in any specific collateral, are higher than those for comparable loans that are secured by specific collateral. For secured loans, there is a risk that the value of any collateral securing a loan in which the Fund has an interest may decline and that the collateral may not be sufficient to cover the amount owed on the loan. Interests in loans made to finance highly leveraged companies or transactions such as corporate acquisitions may be especially vulnerable to adverse changes in economic or market conditions. Loans may have restrictive covenants limiting the ability of a borrower to further encumber its assets. However, in periods of high demand by lenders like the Fund for loan investments, borrowers may limit these covenants and weaken a lender’s ability to access collateral securing the loan; reprice the credit risk associated with the borrower; and mitigate potential loss. The Fund may experience relatively greater realized or unrealized losses or delays and expenses in enforcing its rights with respect to loans with fewer restrictive covenants. Additionally, loans may not be considered “securities” and, as a result, the Fund may not be entitled to rely on the anti-fraud protections of the securities laws. Because junior loans have a lower place in an issuer’s capital structure and may be unsecured, junior loans involve a higher degree of overall risk than senior loans of the issuer. The Fund’s investments in floating rate loans that pay interest based on LIBOR may experience increased volatility and/or illiquidity during the transition away from LIBOR, which is scheduled to be phased out by the end of 2021.

Senior Loan Risk

Senior loans hold the highest priority in the capital structure of a business entity, are typically secured with specific collateral and have a claim on the assets and/or stock of the Borrower that is senior to that held by subordinated debt holders and stockholders of the Borrower. Senior loans that the Fund intends to invest in are usually rated below investment grade, and share the same risks of other below investment grade debt instruments.

Although the Fund may invest in senior loans that are secured by specific collateral, there can be no assurance the liquidation of such collateral would satisfy a Borrower’s obligation to the Fund in the event of Borrower default or that such collateral could be readily liquidated under such circumstances. If the terms of a senior loan do not require the Borrower to pledge additional collateral in the event of a decline in the value of the already pledged collateral, the Fund will be exposed to the risk that the value of the collateral will not at all times equal or exceed the amount of the Borrower’s obligations under the senior loan.

In the event of bankruptcy of a Borrower, the Fund could also experience delays or limitations with respect to its ability to realize the benefits of any collateral securing a senior loan. Some senior loans are subject to the risk that a court, pursuant to fraudulent conveyance or other similar laws, could subordinate the senior loans to presently existing or future indebtedness of the Borrower or take other action detrimental to lenders, including the Fund. Such court action could under certain circumstances include invalidation of senior loans.

81

Issuer Credit Risk

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

Credit Spread Risk

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

Interest Rate Risk

Interest rate risk is the risk that debt securities in the Fund’s portfolio will decline in value because of changes in market interest rates. Generally, when market interest rates rise, the market value of such securities will fall, and vice versa. As interest rates decline, issuers of debt securities may prepay principal earlier than scheduled, forcing the Fund to reinvest in lower-yielding securities and potentially reducing the Fund’s income. As interest rates increase, slower than expected principal payments may extend the average life of securities, potentially locking in a below-market interest rate and reducing the Fund’s value. In typical market interest rate environments, the prices of longer-term debt securities generally fluctuate more than prices of shorter-term debt securities as interest rates change. The Federal Reserve recently reduced the federal funds rate several times. Accordingly, the risks associated with rising interest rates are heightened given that interest rates in the U.S. are near historic lows.

Call Risk

During periods of declining interest rates or for other purposes, issuers may exercise their option to prepay principal earlier than scheduled, forcing the Fund to reinvest in lower yielding instruments. This is known as prepayment or “call” risk. The Fund may invest in securities that are subject to call risk. Debt and preferred instruments may be redeemed at the option of the issuer, or “called,” before their stated maturity or redemption date. In general, an issuer will call its debt or preferred instruments if they can be refinanced by issuing new instruments which bear a lower interest or dividend rate. The Fund is subject to the possibility that during periods of falling interest rates, an issuer will call its high yielding debt or preferred instruments. The Fund would then be forced to invest the unanticipated proceeds at lower interest or dividend rates, resulting in a decline in the Fund’s income.

Reinvestment Risk

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

82

result, the Fund’s income and distributions may decline over the term of the Fund. The likelihood of this risk may increase as the Fund approaches its Termination Date.

Second Lien Loans and Unsecured Loans Risk

Second lien loans and unsecured loans generally are subject to the same risks associated with investments in senior loans, as discussed above. Because second lien loans and unsecured loans are lower in priority of payment to senior loans, they are subject to the additional risk that the cash flow of the borrower and property securing the loan, if any, may be insufficient to meet scheduled payments after giving effect to the senior secured obligations of the borrower. This risk is generally higher for unsecured loans, which are not backed by a security interest in any specific collateral. Second lien loans and unsecured loans are expected to have greater price volatility than senior loans and may be less liquid. Second lien loans and unsecured loans of below investment grade quality also share the same risks of other below investment grade debt instruments. See “—Below Investment Grade Risk.”

Subordinated Loans and Other Subordinated Debt Instruments Risk

Issuers of subordinated loans and other subordinated debt instruments in which the Fund may invest usually will have, or may be permitted to incur, other debt that ranks equally with, or senior to, the subordinated loans or other subordinated debt instruments. By their terms, such debt instruments may provide that the holders are entitled to receive payment of interest or principal on or before the dates on which the Fund is entitled to receive payments in respect of subordinated loans or other subordinated debt instruments in which it invests. Also, in the event of insolvency, liquidation, dissolution, reorganization or bankruptcy of an issuer, holders of debt instruments ranking senior to the subordinated loan or other debt instrument in which the Fund invests would typically be entitled to receive payment in full before the Fund receives any distribution in respect of its investment. After repaying such senior creditors, such issuer may not have any remaining assets to use for repaying its obligation to the Fund. In the case of debt ranking equally with subordinated loans or other subordinated debt instruments in which the Fund invests, the Fund would have to share on an equal basis any distributions with other creditors holding such debt in the event of an insolvency, liquidation, dissolution, reorganization or bankruptcy of the relevant issuer. In addition, the Fund will likely not be in a position to control any issuer by investing in its debt instruments. As a result, the Fund will be subject to the risk that an issuer in which it invests may make business decisions with which the Fund disagrees and the management of such issuer, as representatives of the holders of their common equity, may take risks or otherwise act in ways that do not serve the Fund’s interests as a debt investor.

Inverse Floating Rate Securities Risk

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

The Fund may invest in inverse floating rate securities issued by special purpose trusts that have recourse to the Fund. In Nuveen Fund Advisors’ and Nuveen Asset Management’s discretion, the Fund may enter into a separate shortfall and forbearance agreement with the third party granting liquidity to the floating rate security holders of the special purpose trust. The Fund may enter into such recourse agreements (i) when the liquidity provider to the special purpose trust requires such an agreement because the level of leverage in the trust exceeds the level that the liquidity provider is willing to support absent such an agreement; and/or (ii) to seek to prevent the liquidity provider from collapsing the trust in the event that the municipal obligation held in the trust has declined in value. Such an agreement would require the Fund to reimburse the third party granting liquidity to the

83

floating rate security holders of the special purpose trust, upon termination of the trust issuing the inverse floater, the difference between the liquidation value of the bonds held in the trust and the principal amount due to the holders of floating rate interests. In such instances, the Fund may be at risk of loss that exceeds its investment in the inverse floating rate securities.

Inverse floating rate securities may increase or decrease in value at a greater rate than the underlying interest rate, which effectively leverages the Fund’s investment. As a result, the market value of such securities generally will be more volatile than that of fixed rate securities.

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

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

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

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

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

Bond Market Liquidity Risk

Inventories of bonds held by brokers and dealers have decreased in recent years, lessening their ability to make a market in these securities. This reduction in market making capacity has the potential to decrease the

84

Fund’s ability to buy or sell bonds, and increase bond price volatility and trading costs, particularly during periods of economic or market stress. In addition, recent changes to federal banking regulations may cause certain dealers to reduce their inventories of bonds, which may further decrease the Fund’s ability to buy or sell bonds. As a result, the Fund may be forced to accept a lower price to sell a security, to sell other securities to raise cash, or to give up an investment opportunity, any of which could have a negative effect on performance. If the Fund needed to sell large blocks of bonds, those sales could further reduce the bonds’ prices and hurt performance.

Regulation S Securities Risk

The risk that Regulation S securities may be less liquid than publicly traded securities. Regulation S securities may not be subject to the disclosure and other investor protection requirements that would be applicable to publicly traded securities. As a result, Regulation S securities may involve a high degree of business and financial risk and may result in losses.

Municipal Securities Market Liquidity Risk

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

Restricted and Illiquid Investments Risk

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

85

Defaulted and Distressed Investments Risk

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

Derivatives Risk

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

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

Risk of Swaps and Swap Options

The Fund may enter into derivatives instruments including credit default swap contracts, total return swap contracts and interest rate swaps. Like most derivative instruments, the use of swaps is a highly specialized activity that involves investment techniques and risks different from those associated with ordinary portfolio securities transactions. In addition, the use of swaps requires an understanding by Nuveen Asset Management not only of the referenced asset, rate or index, but also of the swap itself. If 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 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 only close out a swap, cap, floor, collar or other two-party contract with its particular counterparty, and generally may only transfer a position with the consent of that counterparty. Because they are

86

two-party contracts and because they may have terms of greater than seven days, swap agreements may be considered illiquid. 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. Moreover, the Fund bears the risk of loss of the amount expected to be received under a swap agreement in the event of the default or bankruptcy of a swap agreement counterparty. 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.

The Fund may write (sell) and purchase put and call swap options. 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. 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.

It is possible that developments in the derivatives market, including changes in government regulation, could adversely affect the Fund’s ability to terminate existing swap agreements or to realize amounts to be received under such agreements.

Financial Futures and Options Transactions Risk

The Fund may use certain transactions for hedging the portfolio’s exposure to credit risk and the risk of increases in interest rates, which could result in poorer overall performance for the Fund. The Fund’s use of certain transactions to reduce risk involves costs and will be subject to Nuveen Asset Management’s ability to predict correctly changes in the relationships of such hedge instruments to the Fund’s portfolio holdings or other factors. No assurance can be given that Nuveen Asset Management’s judgment in this respect will be correct. In addition, no assurance can be given that the Fund will enter into hedging or other transactions at times or under circumstances in which it may be advisable to do so.

There are certain risks associated with the use of financial futures and options to hedge investment portfolios. There may be an imperfect correlation between price movements of the futures and options and price movements of the portfolio investments being hedged. Losses may be incurred in hedging transactions, which could reduce the portfolio gains that might have been realized if the hedging transactions had not been entered into. If the Fund engages in futures transactions or in the writing of options on futures, it will be required to maintain initial margin and maintenance margin and may be required to make daily variation margin payments in accordance with applicable rules of the exchanges and the Commodity Futures Trading Commission (“CFTC”). If the Fund purchases a financial futures contract or a call option or writes a put option in order to hedge the anticipated purchase of fixed-income investments, and if the Fund fails to complete the anticipated purchase transaction, the Fund may have a loss or a gain on the futures or options transaction that will not be offset by price movements in the fixed-income investments that were the subject of the anticipatory hedge. The cost of put options on debt securities or indexes effectively increases the cost of the securities subject to them, thereby reducing the yield otherwise available from these securities. If the Fund decides to use futures contracts or options on futures contracts for hedging purposes, the Fund will be required to establish an account for such purposes with one or more CFTC-registered futures commission merchants. A futures commission merchant could establish initial and maintenance margin requirements for the Fund that are greater than those which would otherwise apply to the Fund under applicable rules of the exchanges and the CFTC. There can be no assurance that a liquid market will exist at a time when the Fund seeks to close out a derivatives or futures or a futures option position, and the Fund would remain obligated to meet margin requirements until the position is closed. Futures exchanges may limit the amount of fluctuation permitted in certain futures contract prices during a single trading day. The daily limit establishes the maximum amount that the price of a futures contract may vary either up or down from the previous day’s settlement price at the end of the current trading session. Once the daily limit has been reached in a futures contract subject to the limit, no more trades may be made on that day at a price beyond that limit. The daily limit governs only price movements during a particular trading day and therefore does not limit potential losses because the limit may work to prevent the liquidation of unfavorable positions. For

87

example, futures prices have occasionally moved to the daily limit for several consecutive trading days with little or no trading, thereby preventing prompt liquidation of positions and subjecting some holders of futures contracts to substantial losses.

Counterparty Risk

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

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

Tax Risk

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

88

The value of the Fund’s investments and its NAV may be adversely affected by changes in tax rates and rules. For example, although the Fund does not anticipate satisfying the requirements to enable it to pay tax-exempt dividends to shareholders, because interest income from municipal securities is normally not subject to U.S. regular federal income taxation, the attractiveness of municipal securities in relation to other investment alternatives is affected by changes in federal income tax rates or changes in the tax exempt status of interest income from municipal securities. Additionally, the Fund is not a suitable investment for investors seeking primarily tax free income since, as just described, the Fund does not anticipate satisfying the requirements to enable it to pay tax-exempt dividends to shareholders. Also, the Fund’s portfolio turnover is expected to be higher than that of a traditional municipal bond fund and the Fund therefore expects that a greater percentage of each distribution will be capital gains with investors being subject to tax on such distributed gain (depending on the investor’s situation). As a result, the level of taxable distributions currently anticipated by the Fund could be significant for Common Shareholders. Distributions of taxable ordinary income (including any net short-term capital gain) will be taxable to shareholders as ordinary income (and not eligible for favorable taxation as “qualified dividend income”), and capital gain dividends will be taxable as long-term capital gains. Interest income on municipal securities also may be subject to state and local income taxes. See “Tax Matters.”

Hedging Risk

The Fund’s use of derivatives or other transactions to reduce risks involves costs and will be subject to Nuveen Asset Management’s ability to predict correctly changes in the relationships of such hedge instruments to the Fund’s portfolio holdings or other factors. No assurance can be given that Nuveen Asset Management’s judgment in this respect will be correct. In addition, no assurance can be given that the Fund will enter into hedging or other transactions at times or under circumstances in which it may be advisable to do so.

Inflation Risk

Inflation risk is the risk that the value of assets or income from investments will be worth less in the future as inflation decreases the value of money. As inflation increases, the real value of the Common Shares and distributions can decline.

Other Investment Companies Risk

The Fund may invest in the securities of other investment companies, including ETFs. Such securities may be leveraged. As a result, the Fund may be indirectly exposed to leverage through an investment in such securities and therefore magnify the Fund’s leverage risk. Utilization of leverage is a speculative investment technique and involves certain risks. An investment in securities of other investment companies that are leveraged may expose the Fund to higher volatility in the market value of such securities and the possibility that the Fund’s long-term returns on such securities (and, indirectly, the long-term returns of the Common Shares) will be diminished. The Fund, as a holder of the securities of other investment companies, will bear its pro rata portion of the other investment companies’ expenses, including advisory fees. These expenses are in addition to the direct expenses of the Fund’s own operations. As a result, the cost of investing in investment company shares may exceed the costs of investing directly in its underlying investments. Investing in an investment company exposes the Fund to all of the risks of that investment company’s investments. An ETF that is based on a specific index may not be able to replicate and maintain exactly the composition and relative weighting of securities in the index. The value of an ETF based on a specific index is subject to change as the values of its respective component assets fluctuate according to market volatility. ETFs typically rely on a limited pool of authorized participants to create and redeem shares, and an active trading market for ETF shares may not develop or be maintained. The market value of shares of ETFs and closed-end funds may differ from their NAV.

89

Unrated Investments Risk

The Fund may purchase investments that are not rated by any rating organization. Unrated investments determined by Nuveen Asset Management to be of comparable quality to rated investments which the Fund may purchase may pay a higher interest rate than such rated investments and be subject to a greater risk of illiquidity or price changes. Less public information is typically available about unrated investments or issuers than rated investments or issuers. Nuveen Asset Management may, after assessing such investments’ credit quality, internally assign ratings to certain of those securities in categories similar to those of rating organizations. Some unrated investments may not have an active trading market or may be difficult to value, which means the Fund might have difficulty selling them promptly at an acceptable price. To the extent that the Fund invests in unrated investments, the Fund’s ability to achieve its investment objective will be more dependent on Nuveen Asset Management’s credit analysis than would be the case when the Fund invests in rated investments.

Valuation Risk

The investments in which the Fund invests typically are valued by a pricing service utilizing a range of market-based inputs and assumptions, including readily available market quotations obtained from broker-dealers making markets in such instruments, cash flows and transactions for comparable instruments. There is no assurance that the Fund will be able to sell a portfolio investment at the price established by the pricing service, which could result in a loss to the Fund. Pricing services generally price debt securities assuming orderly transactions of an institutional “round lot” size, but some trades may occur in smaller, “odd lot” sizes, often at lower prices than institutional round lot trades. Different pricing services may incorporate different assumptions and inputs into their valuation methodologies, potentially resulting in different values for the same investments. As a result, if the Fund were to change pricing services, or if the Fund’s pricing service were to change its valuation methodology, there could be a material impact, either positive or negative, on the Fund’s NAV.

Fund Level Risks

Market Discount from Net Asset Value

Shares of closed-end investment companies like the Fund frequently trade at prices lower than their NAV, which creates a risk of loss for investors when they sell shares purchased in the initial public offering. This characteristic is a risk separate and distinct from the risk that the Fund’s NAV could decrease as a result of investment activities. 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. Whether investors will realize gains or losses upon the sale of the Common Shares will depend not upon the Fund’s NAV but entirely upon whether the market price of the Common Shares at the time of sale is above or below the investor’s purchase price for the Common Shares. Furthermore, management may have difficulty meeting the Fund’s investment objective and managing its portfolio when the underlying securities are redeemed or sold during periods of market turmoil and as investors’ perceptions regarding closed-end funds or their underlying investments change. Because the market price of the Common Shares will be determined by factors such as relative supply of and demand for the Common Shares in the market, general market and economic circumstances, and other factors beyond the control of the Fund, the Fund cannot predict whether the Common Shares will trade at, below or above NAV or at, below or above the initial public offering price. The Common Shares are designed primarily for long-term investors, and you should not view the Fund as a vehicle for short-term trading purposes.

Investment and Market Risk

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

90

Leverage Risk

The Fund’s anticipated use of leverage creates special risks for Common Shareholders, including potential interest rate risks and the likelihood of greater volatility of NAV and market price of, and distributions on, the Common Shares. The use of leverage in a declining market will likely cause a greater decline in Common Share NAV, which may result at a greater decline of the Common Share price, than if the Fund were not to have used leverage. The Fund will pay (and Common Shareholders will bear) any costs and expenses relating to the Fund’s use of leverage, which will result in a reduction in the NAV of the Common Shares. Nuveen Fund Advisors may, based on its assessment of market conditions, composition of the Fund’s holdings and remaining time until the Fund’s Termination Date, increase or decrease the amount of leverage. Such changes may impact the Fund’s distributions and the price of the Fund’s Common Shares in the secondary market. There is no assurance that the Fund will utilize leverage or that the Fund’s use of leverage will be successful. See “Leverage.”

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

Reverse Repurchase Agreement Risk

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

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

Limited Term and Tender Offer Risks

The Fund is scheduled to terminate as of the Stated Termination Date. The Fund’s investment objective is not designed to return to Common Shareholders their original NAV or purchase price. Because the assets of the Fund will be liquidated in connection with its termination or to pay for Common Shares tendered in an Eligible Tender Offer, the Fund may be required to sell portfolio investments when it otherwise would not, including at times when market conditions are not favorable, or at a time when a particular investment is in default or bankruptcy, or otherwise in severe distress, which may cause the Fund to lose money.

If the Fund conducts an Eligible Tender Offer, and the tender offer is completed, it is anticipated that funds to pay the aggregate purchase price of Common Shares accepted for purchase pursuant to the tender offer will be

91

first derived from any cash on hand and then from the proceeds from the sale of portfolio investments. In addition, the Fund may be required to dispose of portfolio investments in connection with any reduction in its outstanding leverage necessary in order to maintain its desired leverage ratios following an Eligible Tender Offer. The risks related to the disposition of portfolio investments in connection with termination also would be present in connection with the disposition of portfolio investments in connection with an Eligible Tender Offer. It is likely that during the pendency of an Eligible Tender Offer, and possibly for a time thereafter, the Fund will hold a greater than normal percentage of its total assets in money market mutual funds, cash, cash equivalents, securities issued or guaranteed by the U.S. government or its instrumentalities or agencies, high quality, short-term money market instruments, short-term debt securities, certificates of deposit, bankers’ acceptances and other bank obligations, commercial paper or other liquid debt securities, which may adversely affect the Fund’s investment performance. If the tax basis for the portfolio investments sold is less than the sale proceeds, the Fund will recognize capital gains, which it may be required to distribute to Common Shareholders. In addition, the Fund’s purchase of tendered Common Shares pursuant to an Eligible Tender Offer will have tax consequences for tendering Common Shareholders and may have tax consequences for non-tendering Common Shareholders. The purchase of Common Shares pursuant to an Eligible Tender Offer will have the effect of increasing the proportionate interest in the Fund of non-tendering Common Shareholders. All Common Shareholders remaining after an Eligible Tender Offer will be subject to proportionately higher expenses due to the reduction in the Fund’s total assets resulting from payment for the tendered Common Shares. Such reduction in the Fund’s total assets also may result in less investment flexibility, reduced diversification and greater volatility for the Fund, and may have an adverse effect on the Fund’s investment performance.

The Fund is not required to conduct an Eligible Tender Offer. If the Fund conducts an Eligible Tender Offer, there can be no assurance that the number of tendered Common Shares would not result in the Fund’s net assets totaling less than the Termination Threshold, in which case the Eligible Tender Offer will be terminated, no Common Shares will be repurchased pursuant to the Eligible Tender Offer and the Fund will terminate on the Termination Date. Following the completion of an Eligible Tender Offer in which the number of tendered Common Shares would result in the Fund’s net assets totaling greater than the Termination Threshold, the Board of Trustees may provide that the Fund may continue without limitation of time, upon the affirmative vote of a majority of the Board of Trustees and without a vote of shareholders. Thereafter, the Fund will have a continued existence without limitation of time. Nuveen Fund Advisors may have a conflict of interest in recommending to the Board of Trustees that the Fund may have a continued existence without limitation of time. The Fund is not required to conduct additional tender offers following an Eligible Tender Offer and conversion to a continued existence without limitation of time. Therefore, remaining Common Shareholders may not have another opportunity to participate in a tender offer. Shares of closed-end management investment companies frequently trade at a discount from their NAV, and as a result remaining Common Shareholders may only be able to sell their Common Shares at a discount to NAV. See “Risks—Fund Level Risks—Market Discount from Net Asset Value.”

The Fund’s final distribution to Common Shareholders upon termination of the Fund will be based upon the Fund’s NAV at the Termination Date. Any investors who purchase Common Shares in this offering, and any investors who purchase Common Shares after the completion of this offering (particularly if their purchase price differs meaningfully from the original offering price) may receive less than their original investment. Rather than reinvesting the proceeds of its investments, the Fund may also distribute the proceeds in one or more distributions prior to the final liquidation, which may cause the Fund’s fixed expenses to increase when expressed as a percentage of net assets attributable to Common Shares. Depending upon a variety of factors, including the performance of the Fund’s portfolio over the life of the Fund, the amount distributed to Common Shareholders may be significantly less than their original investment.

Because the Fund will invest in below investment grade investments, it may be exposed to the greater potential for an issuer of its investments to default, as compared to a fund that invests solely in investment grade investments. As a result, should a Fund portfolio holding default, this may significantly reduce net investment income and, therefore, Common Share dividends; and may prevent or inhibit the Fund from fully being able to liquidate its portfolio at or prior to the Termination Date. See “—Portfolio Level Risks—Municipal Securities Market Risk”, and “—Below Investment Grade Risk” above.

92

Subsidiary Risk

By investing in the Subsidiary, the Fund is indirectly exposed to the risks associated with the Subsidiary’s investments in Regulation S securities that are not freely tradable in the U.S. Regulation S securities are debt or equity securities of U.S. and foreign issuers offered through private offerings exempt from registration with the SEC pursuant to Regulation S of the 1933 Act. Offerings of Regulation S securities may be conducted outside of the United States, and Regulation S securities may be relatively less liquid as a result of legal or contractual restrictions on resale. Although Regulation S securities may be resold in privately negotiated transactions, the price realized from these sales could be less than the price originally paid by the Fund. Further, companies whose securities are not publicly traded may not be subject to the disclosure of other investor protection requirements that would be applicable is their securities were publicly traded. Accordingly, Regulation S securities may involve a high degree of business and financial risk and may result in substantial. There can be no assurance that the investment objective of the Subsidiary will be achieved. The Subsidiary is not registered under the 1940 Act, and, unless otherwise noted in this prospectus, is not subject to all the investor protections of the 1940 Act. However, the Fund wholly owns and controls the Subsidiary, and the Fund and the Subsidiary are both managed by Nuveen Asset Management making it unlikely that the Subsidiary will take action contrary to the interests of the Fund and its Common Shareholders. The Board of Trustees has oversight responsibility for the investment activities of the Fund, including its investment in the Subsidiary, and the Fund’s role as sole shareholder of the Subsidiary. The Subsidiary is subject to the same investment restrictions and limitations, and follows the same compliance policies and procedures, as the Fund. Changes in the laws of the United States and/or the Cayman Islands could result in the inability of the Fund and/or the Subsidiary to operate as described in this prospectus and the SAI and could adversely affect the Fund.

Frequent Trading Risk

The Fund may engage in active and frequent trading of its portfolio investments, which may result in the Fund having high portfolio turnover. Effects of frequent trading may include high transaction costs, which may lower the Fund’s return, and realization of greater short-term capital gains, distributions of which are taxable as ordinary income to taxable shareholders.

No Operating History

The Fund is a newly organized, diversified, closed-end management investment company with no history of operations. As a result, prospective investors have no track record or history upon which to base their investment decision.

Other Risks

Global Economic Risk

National and regional economies and financial markets are becoming increasingly interconnected, which increases the possibilities that conditions in one country, region or market might adversely impact issuers in a different country, region or market. Changes in legal, political, regulatory, tax and economic conditions may cause fluctuations in markets and investments prices around the world, which could negatively impact the value of the Fund’s investments. Major economic or political disruptions, particularly in large economies like China’s, may have global negative economic and market repercussions. Additionally, the aftermath of the war in Iraq, instability in Afghanistan, Pakistan, Egypt, Libya, Syria, Russia, Ukraine and the Middle East, natural and environmental disasters and the spread of infectious illnesses or other public health emergencies, possible terrorist attacks in the United States and around the world, continued tensions between North Korea and the United States and the international community generally, growing social and political discord in the United States, the European debt crisis, the response of the international community—through economic sanctions and otherwise—to Russia’s annexation of the Crimea region of Ukraine and posture vis-a-vis Ukraine, further downgrade of U.S. Government securities, the change in the U.S. president and the new administration and other

93

similar events may adversely affect the global economy and the markets and issuers in which the Fund invests. Recent examples of such events include the outbreak of a novel coronavirus known as COVID-19 that was first detected in China in December 2019 and heightened concerns regarding North Korea’s nuclear weapons and long-range ballistic missile programs. These events could reduce consumer demand or economic output, result in market closure, travel restrictions or quarantines, and generally have a significant impact on the economy. These events could also impair the information technology and other operational systems upon which the Fund’s service providers, including Nuveen Asset Management, rely, and could otherwise disrupt the ability of employees of the Fund’s service providers to perform essential tasks on behalf of the Fund.

In December 2019, an initial outbreak of COVID-19 was reported and has resulted in numerous deaths and the imposition of both local and more widespread quarantine measures, border closures and other travel restrictions, causing social unrest and commercial disruption on a global scale. In response to the COVID-19 pandemic, central banks and governments have responded with liquidity injections to ease the strain on financial systems and stimulus measures to buffer the shock to businesses and consumers. These measures have helped stabilize the markets over the short term, but volatility will likely remain elevated until the health crisis itself is under control (via fewer new cases, lower infection rates and/or verified treatments). There are still many unknowns and new information is incoming daily, compounding the difficulty of modeling outcomes for epidemiologists and economists alike.

Additionally, the recent outbreak of COVID-19 has adversely impacted global commercial activity and has contributed to significant volatility in certain financial markets. There are no comparable recent events in the U.S. that provide guidance as to the effect of the spread of COVID-19 and a potential pandemic on the economy as a whole and, consequently, the Fund. Accordingly, while there have been proposed, and in some cases enacted, economic stimulus measures aimed at curbing the negative economic impacts to the U.S. and other countries as a result of COVID-19, it cannot be determined at this time whether such stimulus measures will have a stabilizing economic effect.

To the extent the impacts of COVID-19 continue, the Fund may experience negative impacts to its business that could exacerbate other risks to which the Fund is subject, including: (1) issuers of fixed-income investments could be materially impacted by the COVID-19 pandemic, which may, in turn, negatively affect the value of such investments or such issuers’ ability to make interest payments or distributions to the Fund and result in a decrease in the NAV of the Fund; (2) operational impacts on and availability of key personnel of Nuveen Fund Advisors, Nuveen Asset Management, and/or any of the Fund’s other service providers, vendors and counterparties as they face changed circumstances and/or illness related to the pandemic; and (3) limitations on the Fund’s ability to make distributions or dividends, as applicable, to Common Shareholders.

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

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

94

Recent Market Conditions

In response to the financial crisis and recent market events, the United States and other governments and the Federal Reserve and certain foreign central banks have taken steps to support financial markets. Policy and legislative changes by the United States government and the Federal Reserve to assist in the ongoing support of financial markets, both domestically and in other countries, are changing many aspects of financial regulation. The impact of these changes on the markets, and the practical implications for market participants, may not be fully known for some time. In some countries where economic conditions are recovering, such countries are nevertheless perceived as still fragile. Withdrawal of government support, failure of efforts in response to the crisis, or investor perception that such efforts are not succeeding, could adversely impact the value and liquidity of certain investments. The severity or duration of adverse economic conditions may also be affected by policy changes made by governments or quasi-governmental organizations, including changes in tax laws and the imposition of trade barriers. The impact of new financial regulation legislation on the markets and the practical implications for market participants may not be fully known for some time. Changes to the Federal Reserve policy, including with respect to certain interest rates, may affect the value, volatility and liquidity of dividend and interest paying securities. Regulatory changes are causing some financial services companies to exit long-standing lines of business, resulting in dislocations for other market participants. In addition, the contentious domestic political environment, as well as political and diplomatic events within the United States and abroad, such as the U.S. government’s inability at times to agree on a long-term budget and deficit reduction plan, the threat of a federal government shutdown and threats not to increase the federal government’s debt limit, may affect investor and consumer confidence and may adversely impact financial markets and the broader economy, perhaps suddenly and to a significant degree. The U.S. government has recently reduced the federal corporate income tax rate, and future legislative, regulatory and policy changes may result in more restrictions on international trade, less stringent prudential regulation of certain players in the financial markets, and significant new investments in infrastructure and national defense. Markets may react strongly to expectations about the changes in these policies, which could increase volatility, especially if the markets’ expectations for changes in government policies are not borne out.

Changes in market conditions will not have the same impact on all types of investments. Interest rates have been unusually low in recent years in the United States and abroad, but there is a consensus that interest rates will increase during the life of the Fund, which could negatively impact the price of debt securities. Because there is little precedent for this situation, it is difficult to predict the impact of a significant rate increase on various markets. For example, because investors may buy securities or other investments with borrowed money, a significant increase in interest rates may cause a decline in the markets for those investments. Because of the sharp decline in the worldwide price of oil, there is a concern that oil producing nations may withdraw significant assets now held in U.S. Treasuries, which could force a substantial increase in interest rates. Regulators have expressed concern that rate increases may cause investors to sell fixed income securities faster than the market can absorb them, contributing to price volatility. In addition, there is a risk that the prices of goods and services in the United States and many foreign economies may decline over time, known as deflation (the opposite of inflation). Deflation may have an adverse effect on stock prices and creditworthiness and may make defaults on debt more likely. If a country’s economy slips into a deflationary pattern, it could last for a prolonged period and may be difficult to reverse.

On June 23, 2016, the United Kingdom (“UK”) held a referendum on whether to remain a member state of the European Union (“EU”), in which voters favored the UK’s withdrawal from the EU, an event widely referred to as “Brexit” and which triggered a two-year period of negotiations on the terms of withdrawal. The formal notification to the European Council required under Article 50 of the Treaty on EU was made on March 29, 2017, following which the terms of exit were negotiated. On January 31, 2020, the UK formally withdrew from the EU. The longer term economic, legal, political and social framework to be put in place between the UK and the EU are unclear at this stage, remain subject to negotiation and are likely to lead to ongoing political and economic uncertainty and periods of exacerbated volatility in both the UK and in wider European markets for some time. The outcomes may cause increased volatility and have a significant adverse impact on world financial markets, other international trade agreements, and the UK and European economies, as well as the broader global

95

economy for some time. Additionally, a number of countries in Europe have suffered terror attacks, and additional attacks may occur in the future. Ukraine has experienced ongoing military conflict; this conflict may expand and military attacks could occur elsewhere in Europe. Europe has also been struggling with mass migration from the Middle East and Africa. The ultimate effects of these events and other socio-political or geographical issues are not known but could profoundly affect global economies and markets.

The current political climate has intensified concerns about a potential trade war between China and the United States, as each country has recently imposed tariffs on the other country’s products. These actions may trigger a significant reduction in international trade, the oversupply of certain manufactured goods, substantial price reductions of goods and possible failure of individual companies and/or large segments of China’s export industry, which could have a negative impact on the Fund’s performance. U.S. companies that source material and goods from China and those that make large amounts of sales in China would be particularly vulnerable to an escalation of trade tensions. Uncertainty regarding the outcome of the trade tensions and the potential for a trade war could cause the U.S. dollar to decline against safe haven currencies, such as the Japanese yen and the euro. Events such as these and their consequences are difficult to predict and it is unclear whether further tariffs may be imposed or other escalating actions may be taken in the future.

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

Legislation and Regulatory Risk

At any time after the date of this prospectus, legislation or additional regulations may be enacted that could negatively affect the assets of the Fund, investments held by the Fund or the issuers of such investments. Changing approaches to regulation may have a negative impact on the entities and/or investments in which the Fund invests. Legislation or regulation may also change the way in which the Fund itself is regulated. Fund shareholders may incur increased costs resulting from such legislation or additional regulation. There can be no assurance that future legislation, regulation or deregulation will not have a material adverse effect on the Fund or will not impair the ability of the Fund to achieve its investment objective.

For example, the Dodd-Frank Act is designed to impose stringent regulation on the over-the-counter derivatives market in an attempt to increase transparency and accountability and provides for, among other things, new clearing, execution, margin, reporting, recordkeeping, business conduct, disclosure, position limit, minimum net capital and registration requirements. Although the CFTC has released final rules under the Dodd-Frank Act, many of the provisions are subject to further final rulemaking, and thus the Dodd-Frank Act’s ultimate impact remains unclear.

The SEC recently new Rule 18f-4 under the 1940 Act governing the use of derivatives by registered investment companies, which could affect the nature and extent of derivatives used by the Fund. It is possible that new Rule 18f-4 could limit the implementation of the Fund’s use of derivatives, which could have an adverse impact on the Fund.

Additionally, the Fund is operated by persons who have claimed an exclusion, granted to operators of registered investment companies like the Fund, from registration as a “commodity pool operator” under Rule 4.5 promulgated by the CFTC pursuant to its authority under the Commodity Exchange Act (the “CEA”) and, therefore, is not subject to registration or regulation as a “commodity pool operator.” As a result, the Fund is limited in its ability to use commodity futures (which include futures on broad-based securities indexes and interest rate futures) or options on commodity futures, engage in swaps transactions or make certain other investments (whether directly or indirectly through investments in other investment vehicles) for purposes other than bona fide hedging. With respect to transactions other than for bona fide hedging purposes, either: (1) the aggregate initial margin and premiums required to establish the Fund’s positions in such investments may not exceed 5% of the liquidation value of the Fund’s portfolio (after accounting for unrealized profits and unrealized

96

losses on any such investments); or (2) the aggregate net notional value of such instruments, determined at the time the most recent position was established, may not exceed 100% of the liquidation value of the Fund’s portfolio (after accounting for unrealized profits and unrealized losses on any such positions). In addition to meeting one of the foregoing trading limitations, the Fund may not market itself as a commodity pool or otherwise as a vehicle for trading in the futures, options or swaps markets. If the Fund does not continue to claim the exclusion, it would likely become subject to registration and regulation as a commodity pool operator. The Fund may incur additional expenses as a result of the CFTC’s registration and regulatory requirements.

LIBOR Replacement Risk

The use of the LIBOR will be phased out by the end of 2021. This may adversely affect the Fund’s investments whose value is tied to LIBOR. There remains uncertainty regarding the future use of LIBOR and the nature of any replacement reference rate. Actions by regulators have resulted in the establishment of alternative reference rates to LIBOR in most major currencies and markets are slowly developing in response to these new rates. The transition process away from LIBOR may involve, among other things, increased volatility or illiquidity in markets for instruments that currently rely on LIBOR. The potential effect of a discontinuation of LIBOR on the Fund’s investments will vary depending on, among other things: (1) existing fallback provisions that provide a replacement reference rate if LIBOR is no longer available; (2) termination provisions in individual contracts; and (3) whether, how, and when industry participants develop and adopt new reference rates and fallbacks for both legacy and new products and instruments. Accordingly, it is difficult to predict the full impact of the transition away from LIBOR until new reference rates and fallbacks are commercially accepted.

Anti-Takeover Provisions

The Fund’s 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 convert the Fund to open-end status. These provisions could have the effect of depriving the Common Shareholders of opportunities to sell their Common Shares at a premium over the then-current market price of the Common Shares. See “Certain Provisions in the Declaration of Trust and By-Laws.”

Potential Conflicts of Interest Risk

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

For additional information about potential conflicts of interest, and the way in which Nuveen Fund Advisors and Nuveen Asset Management address such conflicts, please see “Subadviser—Nuveen Asset Management Conflict of Interest Policies” in the SAI.

The following risks are not considered to be principal risks of investing in the Fund:

Income Risk

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

97

Deflation Risk

Deflation risk is the risk that prices throughout the economy decline over time, which may have an adverse effect on the market valuation of companies, their assets and revenues. In addition, deflation may have an adverse effect on the creditworthiness of issuers and may make issuer default more likely, which may result in a decline in the value of the Fund’s portfolio.

Risks Related to the Fund’s Clearing Broker and Central Clearing Counterparty

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

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

Borrowing Risk

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

98

Duration Risk

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

Senior Loan Agent Risk

A financial institution’s employment as an Agent under a senior loan might be terminated in the event that it fails to observe a requisite standard of care or becomes insolvent. A successor Agent would generally be appointed to replace the terminated Agent, and assets held by the Agent under the loan agreement would likely remain available to holders of such indebtedness. However, if assets held by the terminated Agent for the benefit of the Fund were determined to be subject to the claims of the Agent’s general creditors, the Fund might incur certain costs and delays in realizing payment on a senior loan or loan participation and could suffer a loss of principal and/or interest. In situations involving other interposed financial institutions (e.g., an insurance company or government agency) similar risks may arise.

Asset Segregation Risk

Certain portfolio management techniques, such as, among other things, using reverse repurchase agreements, purchasing investments on a when-issued or delayed delivery basis or entering into swap agreements, futures contracts or other derivative transactions, create leverage or its effect, and may be considered “senior securities’” (as that term is defined under the 1940 Act). To avoid having these instruments considered “senior securities,” the Fund may maintain liquid assets with its custodian in an amount with a value at least equal (on a daily market value basis or notional value basis, as applicable) to the aggregate amount of its obligations under these types of leveraging transactions (often referred to as “asset segregation”), enter into offsetting transactions, or otherwise “cover” certain transactions, in accordance with the 1940 Act, the rules thereunder, and applicable positions of the SEC and its staff. The SEC recently adopted new Rule 18f-4 under the 1940 Act, which imposes limits on replaces the asset segregation framework previously used by funds to comply with Section 18 of the 1940 Act, among other requirements. The Fund will comply with the new rule’s requirements on or before the SEC’s compliance date in 2022. See “Portfolio Composition and Other Information—Asset Segregation” above. In the event that the Fund is unable to maintain sufficient assets, or otherwise “cover,” any open positions, a portion or all of these instruments will be classified as a “senior security” for 1940 Act purposes and be subject to certain limitations on “senior securities” under the 1940 Act. See “Leverage” above. The Fund may be restricted in its use of assets that are maintained for “asset segregation,” or committed as “cover,” for certain other purposes, which could result in the Fund earning a lower return on its portfolio than it might otherwise earn if it did not have to maintain those assets in respect of, or otherwise “cover,” such portfolio positions. To the extent the Fund’s assets are maintained or committed as “cover,” it could limit the Fund’s investment flexibility. Maintaining assets and covering positions will not limit or offset losses on the related leveraging positions.

Special Risks Related to Certain Municipal Obligations

Municipal leases and certificates of participation involve special risks not normally associated with general obligations or revenue bonds. Leases and installment purchase or conditional sale contracts (which normally provide for title to the leased asset to pass eventually to the governmental issuer) have evolved as a means for governmental issuers to acquire property and equipment without meeting the constitutional and statutory

99

requirements for the issuance of debt. The debt issuance limitations are deemed to be inapplicable because of the inclusion in many leases or contracts of “non-appropriation” clauses that relieve the governmental issuer of any obligation to make future payments under the lease or contract unless money is appropriated for such purpose by the appropriate legislative body. In addition, such leases or contracts may be subject to the temporary abatement of payments in the event that the governmental issuer is prevented from maintaining occupancy of the leased premises or utilizing the leased equipment. Although the obligations may be secured by the leased equipment or facilities, the disposition of the property in the event of non-appropriation or foreclosure might prove difficult, time consuming and costly, and may result in a delay in recovering or the failure to fully recover the Fund’s original investment. In the event of non-appropriation, the issuer would be in default and taking ownership of the assets may be a remedy available to the Fund, although the Fund does not anticipate that such a remedy would normally be pursued.

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

Cybersecurity Risk

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

Certain Affiliations

Certain broker-dealers may be considered to be affiliated persons of the Fund, Nuveen Fund Advisors, Nuveen Asset Management, Nuveen and/or TIAA. Absent an exemption from the SEC or other regulatory relief, the Fund generally is precluded from effecting certain principal transactions with affiliated brokers, and its ability to purchase investments being underwritten by an affiliated broker or a syndicate including an affiliated broker, or to utilize affiliated brokers for agency transactions, is subject to restrictions. The Fund has not applied for and does not currently intend to apply for such relief. This could limit the Fund’s ability to engage in investments transactions and take advantage of market opportunities. In addition, unless and until the underwriting syndicate is broken in connection with the initial public offering of the Common Shares, the Fund will be precluded from effecting principal transactions with brokers who are members of the syndicate.
