Nuveen Variable Rate Preferred & Income Fund

Common Shares

$25.00 per Share

The Fund.    Nuveen Variable Rate Preferred & Income Fund (the “Fund”) is a newly organized, diversified, closed-end management investment company. The Fund’s investment objective is to seek to provide a high level of current income and total return. 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 a portfolio of variable rate preferred securities and other variable rate income producing securities. The Fund’s portfolio will be actively managed to capitalize on the relative value opportunities of different instrument types, including but not limited to securities with different variable rate coupon structures, and to invest in securities so that all, or almost all, of the Fund’s distributions of net investment income will be treated as qualified dividend income (“QDI”).

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                                          (“            ”), subject to notice of issuance. The trading or “ticker” symbol is “                .”

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, including the risks associated with the Fund’s use of leverage. 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 76 of this prospectus. Certain of these risks are summarized in “Prospectus Summary—Special Risk Considerations” beginning on page 18 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.

Table of Contents

Investment Policies.    Under normal circumstances the Fund will invest at least 80% of its Assets (as defined on page 9) in variable rate preferred securities and other variable rate income producing securities. The Fund may invest up to 20% of its Managed Assets (as defined on page 9) in contingent capital securities or contingent convertible securities (sometimes referred to as “CoCos”). The Fund will invest at least 50% of its Managed Assets in securities that, at the time of investment, are rated investment grade (rated BBB/Baa or higher) or are unrated but judged to be of comparable quality by the Fund’s sub-adviser. The Fund may invest up to 15% of its Managed Assets in companies located in emerging market countries. The Fund will invest in U.S. dollar denominated securities. Additionally, the Fund will invest more than 25% of its Managed Assets in the securities of companies principally engaged in financial services.

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 securities 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 37% of the Fund’s Managed Assets, if current market conditions persist. The Fund currently intends to employ leverage through borrowings and or reverse repurchase agreements as well as the issuance of preferred shares of beneficial interest within 12 months after the completion of this offering. The issuance of Preferred Shares may only be done if the Board of Trustees of the Fund (the “Board of Trustees”) determines it to be in the best interests of Common Shareholders. 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 — 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 (the “Stated Termination Date”), provided that if the Stated Termination Date would otherwise fall in the month of January, the Stated Termination Date shall be the first business day of the month of February that next follows the twelfth anniversary from such date of effectiveness. The Stated Termination Date is currently anticipated to be              1, 2033. However, 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

Table of Contents

“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 repurchase of all 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 repurchase of all Common Shares properly tendered in an Eligible Tender Offer would result in the Fund’s net assets totaling less than the Termination Threshold, 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 declare and pay monthly distributions to Common Shareholders at a stable rate (stated in terms of a fixed cents per Common Share dividend rate) based on the past and projected net income performance of the Fund. The Fund currently expects that it will seek, subject to market conditions and the composition of its investment portfolio, for all or almost all of its distributions of net investment income to be treated as qualified dividend income QDI. However, not all income distributions may qualify for treatment as QDI. The tax treatment and characterization of the Fund’s distributions may vary significantly from time to time because of the varied nature of the Fund’s investments. The ultimate tax characterization of the Fund’s distributions made in a taxable year cannot be determined finally until after the end of that taxable year.

To help maintain more stable monthly distributions, the distribution paid by the Fund for any particular monthly period may be more or less than the amount of net income actually earned by the Fund during such period, and any such under-(or over-) distribution of income is reflected in the Fund’s NAV.

The Fund’s ability to maintain a stable Common Share dividend rate will depend on a number of factors, including expenses related to the Fund’s use of leverage. As portfolio and market conditions change, the rate of dividends on the Common Shares and the Fund’s dividend policy could change. The Fund also intends to declare and pay any taxable capital gains or other taxable distributions once a year at year end. See “Distributions.”

Table of Contents

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.

2

Table of Contents

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.

Contingent Capital Securities or Contingent Convertible Securities

The Fund may also invest in contingent capital securities or contingent convertible securities (sometimes referred to as “CoCos”). CoCos are hybrid securities, issued primarily by non-U.S. financial institutions, which have loss absorption mechanisms benefitting the issuer built into their terms. CoCos are not preferred securities. CoCos provide for mandatory conversion into the common stock of the issuer or a permanent or temporary full or partial write-down of the principal amount of the security upon the occurrence of certain triggers linked to minimum regulatory capital thresholds. In addition, they may explicitly provide for mandatory conversion or a principal write-down

3

Table of Contents

upon the occurrence of certain events such as regulatory bodies calling into question the issuing institution’s continued viability as a going-concern. Equity conversion or principal write-down features are tailored to the issuer and its regulatory requirements and, unlike traditional convertible securities, conversions are not voluntary and are not intended to benefit the investor.

The Fund may invest in corporate debt securities issued by companies of all kinds, including those with small-, mid- and large capitalizations. Corporate debt securities are fixed income securities issued by businesses to finance their operations. Notes, bonds, debentures and commercial paper are the most common types of corporate debt securities, with the primary difference being their maturities and secured or unsecured status. Commercial paper has the shortest term and is usually unsecured. Corporate debt securities may be rated investment-grade or below investment-grade and may carry fixed or floating rates of interest.

The fund may invest in U.S. government securities, including U.S. Treasury obligations and securities issued or guaranteed by various agencies of the U.S. government, or by various instrumentalities which have been established or sponsored by the U.S. government. U.S. Treasury obligations are backed by the “full faith and credit” of the U.S. government. Securities issued or guaranteed by federal agencies and U.S. government sponsored instrumentalities may or may not be backed by the full faith and credit of the U.S. government.

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.

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

4

Table of Contents

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.

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.

A mortgage-backed security (“MBS”) 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.

5

Table of Contents

The Fund may invest in loans, including senior secured loans, unsecured and/or subordinated loans, loan participations, unfunded contracts and assignments. 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 (“LIBOR”), 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.

To help maintain more stable monthly distributions, the distribution paid by the Fund for any particular monthly period may be more or less than the amount of net income actually earned by the Fund during such period, and any such under-(or over-) distribution of income is reflected in the Fund’s NAV. The Fund’s ability to maintain a stable Common Share dividend rate will depend on a number of factors, including expenses related to the Fund’s use of leverage, as applicable. As portfolio and market conditions change, the rate of dividends on the Common Shares and the Fund’s dividend policy could change. For each taxable year, the Fund will distribute all or substantially all of its net investment income (after it pays for any expenses related to the Fund’s use of leverage). The Fund expects to declare its initial Common Share distribution within approximately 45 days following the completion of this offering, and to pay that distribution on or about                 , 2021, depending on market conditions.

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 dividend or interest rate than such rated investments and be

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

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.”

47

Table of Contents

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.

Table of Contents

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 June 1, 2021, pursuant to the Fund’s Declaration of Trust (the “Declaration of Trust”). 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 to provide a high level of current income and total return. There can be no assurance that the Fund will achieve its investment objective or that the Fund’s investment strategies will be successful. The Fund’s investment objective may be changed by the Board of Trustees of the Fund (the “Board of Trustees”) without shareholder approval.

Fund Strategies

The Fund seeks to achieve its investment objective by investing in a portfolio of variable rate preferred securities and other variable rate income producing securities. The Fund’s portfolio will be actively managed to capitalize on the relative value opportunities of different instrument types, including but not limited to securities with different variable rate coupon structures, and to invest in securities so that all, or almost all, of the Fund’s distributions of net investment income will be treated as qualified dividend income (“QDI”).

Portfolio Contents

The Fund will generally invest in variable rate preferred securities and other variable rate income producing securities. The Fund may also invest to a lesser extent in fixed income securities, of any type, including contingent capital securities or contingent convertible securities (sometimes referred to as “CoCos”), convertible

49

Table of Contents

securities, corporate debt securities, residential and commercial mortgage-backed securities, taxable and tax-exempt municipal bonds, fixed-rate preferred securities, 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).

While the Fund does not currently anticipate investing to a material extent in restricted and illiquid investments (i.e., investments that are not readily marketable), the Fund’s portfolio may contain restricted and illiquid investments, 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 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.

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 derivative instruments. Nuveen Asset Management may use derivative instruments to attempt to hedge some of the risk of the Fund’s investments 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 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 market conditions:

The foregoing policies apply only at the time of any new investment. The Fund’s policy to invest at least 80% of its Assets in variable rate preferred securities and other variable rate income producing securities, may not be changed without 60 days’ prior written notice to shareholders.

50

Table of Contents

The Fund will invest predominantly in securities with variable rate coupon structures that may be broadly characterized as follows:

“Assets” means net assets of the Fund plus the amount of any borrowings for investment purposes. “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.

A financial services company is one that is primarily involved in banking, mortgage finance, consumer finance, specialized finance, investment banking and brokerage, asset management and custody, corporate lending, insurance, financial instruments or real estate, including business development companies (“BDCs”) and real estate investment trusts (“REITs”). For purposes of identifying companies in the financial services sector, the Fund uses industry classifications such as those provided by MSCI and Standard & Poor’s The Global Industry Classification Standard, Bloomberg, Barclays or similar sources commonly used in the financial industry. As a result, if one or more of these classifications include a company in the financial services sector, the Fund considers such company as being in the financial services sector.

Investment grade quality securities are those securities that, at the time of investment, are rated by at least one NRSRO within the four highest grades (Baa or BBB or better by Moody’s Investors Service, Inc. (“Moody’s”), Standard & Poor’s Corporation, a division of The McGraw-Hill Companies (“S&P”), or Fitch Ratings (“Fitch”)), or are unrated but judged to be of comparable quality by the Nuveen Asset Management. The Fund may invest in securities of below investment grade quality, commonly referred to as “high yield” or “junk” bonds, which are regarded as having predominantly speculative characteristics with respect to the issuer’s capacity to pay interest and repay principal when due, and they are more susceptible to default or decline in market value due to adverse economic and business developments than investment grade securities. 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 (i.e., a privately negotiated, mutual agreement between the Fund and the issuer or another party) 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 investments, the Fund considers a country an emerging market country based on the determination of an international organization, such as the IMF, or an unaffiliated, recognized financial data provider.

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 net asset value (“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 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 (the “Stated Termination Date”), provided that if the Stated Termination Date would otherwise fall in the month of January, the Stated Termination Date shall be the first business day of the month of February that next follows the twelfth anniversary from such date of effectiveness. The Stated Termination Date is currently anticipated to be              1, 2033. However, 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 repurchase of all 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 Securities Exchange Act of 1934, as amended (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 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,

53

Table of Contents

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.”

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

54

Table of Contents

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.

Convertible Preferred Securities

The Fund’s investments in preferred securities may include convertible preferred securities, which are hybrid securities that combine the investment characteristics of bonds and common stocks. Convertible preferred securities typically consist of preferred securities that may be converted within a specified period of time (typically for the entire life of the security) into a certain amount of common stock or other equity security of the same or a different issuer. Convertible preferred securities entitle the holder to receive interest or dividends paid or accrued on preferred securities until the securities mature or are redeemed, converted or exchanged.

Contingent Capital Securities or Contingent Convertible Securities

The Fund may also invest in contingent capital securities or contingent convertible securities (sometimes referred to as “CoCos”). CoCos are hybrid securities, issued primarily by non-U.S. financial institutions, which have loss absorption mechanisms benefitting the issuer built into their terms. CoCos are not preferred securities. CoCos provide for mandatory conversion into the common stock of the issuer or a permanent or temporary full or partial write-down of the principal amount of the security upon the occurrence of certain triggers linked to minimum regulatory capital thresholds. In addition, they may explicitly provide for mandatory conversion or a

55

Table of Contents

principal write-down upon the occurrence of certain events such as regulatory bodies calling into question the issuing institution’s continued viability as a going-concern. Equity conversion or principal write-down features are tailored to the issuer and its regulatory requirements and, unlike traditional convertible securities, conversions are not voluntary and are not intended to benefit the investor.

Corporate Debt Securities

The Fund may invest in corporate debt securities issued by companies of all kinds, including those with small-, mid- and large capitalizations. Corporate debt securities are fixed income securities issued by businesses to finance their operations. Notes, bonds, debentures and commercial paper are the most common types of corporate debt securities, with the primary difference being their maturities and secured or unsecured status. Commercial paper has the shortest term and is usually unsecured. Corporate debt securities may be rated investment-grade or below investment-grade and may carry fixed or floating rates of interest.

U.S. Government Securities

The fund may invest in U.S. government securities, including U.S. Treasury obligations and securities issued or guaranteed by various agencies of the U.S. government, or by various instrumentalities which have been established or sponsored by the U.S. government. U.S. Treasury obligations are backed by the “full faith and credit” of the U.S. government. Securities issued or guaranteed by federal agencies and U.S. government sponsored instrumentalities may or may not be backed by the full faith and credit of the U.S. government.

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 U.S. 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 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.

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

56

Table of Contents

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).

Asset-Backed Securities

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 mortgage-backed securities (“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.

Mortgage-Backed Securities, including Commercial Mortgage-Backed Securities

The Funds may invest in mortgage-backed securities. A mortgage-backed security is a type of passthrough 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.

Mortgage-backed securities are most commonly issued or guaranteed by the Government National Mortgage Association (“Ginnie Mae” or “GNMA”), the Federal National Mortgage Association (“Fannie Mae” or “FNMA”) or the Federal Home Loan Mortgage Corporation (“Freddie Mac” or “FHLMC”), 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/

57

Table of Contents

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 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

58

Table of Contents

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 LIBOR, 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.

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

59

Table of Contents

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 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 Risk.”

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

60

Table of Contents

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.

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

61

Table of Contents

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 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.

Other Equity Securities

The Fund may invest in common stocks which generally represents an equity ownership interest in an issuer. Although common stocks have historically generated higher average total returns than fixed-income securities over the long term, common stocks also have experienced significantly more volatility in those returns and may underperform relative to fixed-income securities during certain periods. An adverse event, such as an unfavorable earnings report, may depress the value of a particular common stock held by the Fund. Also, prices

62

Table of Contents

of common stocks are sensitive to general movements in the stock market and a drop in the stock market may depress the price of common stocks to which the Fund has exposure. Common stock prices fluctuate for several reasons including changes in investors’ perceptions of the financial condition of an issuer or the general condition of the relevant stock market, or the occurrence of political or economic events which affect the issuer. In addition, common stock prices may be particularly sensitive to rising interest rates, which increases borrowing costs and the costs of capital.

Additional types of equity securities (other than preferred securities) in which the Fund may invest include convertible securities (discussed below), REITs, warrants, rights, depositary receipts (which reference ownership of underlying non-U.S. securities) and other types of securities with equity characteristics. The Fund’s equity investments also may include securities of other investment companies (including open-end funds, closed-end funds and ETFs).

Convertible Securities

Convertible securities are hybrid securities that combine the investment characteristics of bonds and common stocks. Convertible securities typically consist of debt securities or preferred securities that may be converted within a specified period of time (typically for the entire life of the security) into a certain amount of common stock or other equity security of the same or a different issuer at a predetermined price. They also include debt securities with warrants or common stock attached and derivatives combining the features of debt securities and equity securities. Convertible securities entitle the holder to receive interest paid or accrued on debt, or dividends paid or accrued on preferred securities, until the security matures or is redeemed, converted or exchanged.

The market value of a convertible security generally is a function of its “investment value” and its “conversion value.” A security’s “investment value” represents the value of the security without its conversion feature (i.e., a comparable non-convertible fixed income security). The investment value is determined by, among other things, reference to its credit quality and the current value of its yield to maturity or probable call date. At any given time, investment value is dependent upon such factors as the general level of interest rates, the yield of similar non-convertible securities, the financial strength of the issuer and the seniority of the security in the issuer’s capital structure. A security’s “conversion value” is determined by multiplying the number of shares the holder is entitled to receive upon conversion or exchange by the current price of the underlying security. If the conversion value of a convertible security is significantly below its investment value, the convertible security will trade like non-convertible debt or a preferred security in the sense that its market value will not be influenced greatly by fluctuations in the market price of the underlying security into which it can be converted. Instead, the convertible security’s price will tend to move in the opposite direction from interest rates. Conversely, if the conversion value of a convertible security is significantly above its investment value, the market value of the convertible security will be more heavily influenced by fluctuations in the market price of the underlying stock. In that case, the convertible security’s price may be as volatile as that of the common stock. Because both interest rate and market movements can influence its value, a convertible security is not generally as sensitive to interest rates as a similar fixed income security, nor is it generally as sensitive to changes in share price as its underlying stock.

The Fund’s investments in convertible securities, particularly securities that are convertible into securities of an issuer other than the issuer of the convertible security, may be illiquid. The Fund’s investments in convertible securities may at times include securities that have a mandatory conversion feature, pursuant to which the securities convert automatically into common stock or other equity securities (of the same or a different issuer) at a specified date and a specified conversion ratio, or that are convertible at the option of the issuer. For issues where the conversion of the security is not at the option of the holder, the Fund may be required to convert the security into the underlying common stock even at times when the value of the underlying common stock or other equity security has declined substantially.

63

Table of Contents

In addition, some convertible securities are often rated below investment-grade or are not rated, and therefore may be considered speculative investments. The credit rating of a company’s convertible securities is generally lower than that of its conventional debt securities. Convertible securities are normally considered “junior” securities—that is, the company usually must pay interest on its conventional corporate debt before it can make payments on its convertible securities. Some convertible securities are particularly sensitive to interest rate changes when their predetermined conversion price is much higher than the issuing company’s common stock.

Emerging Market Issuers

The Fund will invest in investments of emerging market issuers. The Fund considers a country an emerging market country based on the determination of an international organization, such as the IMF, or an unaffiliated, recognized financial data provider.

Non-U.S. Securities

The Fund may invest in U.S. dollar-denominated securities issued by non-U.S. companies. Investments in securities of non-U.S. companies involve risks in addition to the usual risks inherent in domestic investments.

Non-U.S. securities are affected by the fact that in many countries there is less publicly available information about issuers than is available in the reports and ratings published about companies in the United States and such issuers may not be subject to uniform accounting, auditing and financial reporting standards. Other risks inherent in non-U.S. investments include expropriation; confiscatory taxation; withholding taxes on dividends and interest; less extensive regulation of non-U.S. brokers, securities markets and issuers; diplomatic developments; and political or social instability. Non-U.S. economies may differ favorably or unfavorably from the U.S. economy in various respects, and many non-U.S. securities are less liquid and their prices tend to be more volatile than comparable U.S. securities. From time to time, non-U.S. securities may be difficult to liquidate rapidly without adverse price effects.

The Fund may also invest in non-U.S. securities by purchasing depositary receipts, including American Depositary Receipts (“ADRs”), European Depositary Receipts (“EDRs”), Global Depositary Receipts (“GDRs”) or other securities representing indirect ownership interests in the securities of non-U.S. companies, including New York Shares. Generally, ADRs, in registered form, are denominated in U.S. dollars and are designated for use in the U.S. securities markets, while EDRs and GDRs are typically in bearer form and may be denominated in non-U.S. currencies and are designed for use in European and other markets. ADRs are receipts typically issued by a U.S. bank or trust company evidencing ownership of the underlying non-U.S. security. ADRs, EDRs and GDRs are deemed to have the same classification as the underlying securities they represent, except that ADRs, EDRs and GDRs shall be treated as indirect non-U.S. investments. Thus, an ADR, EDR or GDR representing ownership of common stock will be treated as common stock. ADRs, EDRs and GDRs do not eliminate all of the risks associated with directly investing in the securities of non-U.S. companies. However, by investing in ADRs rather than directly in non-U.S. companies’ stock, the Fund avoids currency risks during the settlement period.

Other types of depositary receipts include American Depositary Shares (“ADSs”), Global Depositary Certificates (“GDCs”) and International Depositary Receipts (“IDRs”). ADSs are shares issued under a deposit agreement representing the underlying ordinary shares that trade in the issuer’s home market. An ADR, described above, is a certificate that represents a number of ADSs. GDCs and IDRs are typically issued by a non-U.S. bank or trust company, although they may sometimes also be issued by a U.S. bank or trust company. GDCs and IDRs are depositary receipts that evidence ownership of underlying securities issued by either a non-U.S. or a U.S. corporation.

Depositary receipts may be available through “sponsored” or “unsponsored” facilities. A sponsored facility is established jointly by a depositary and the issuer of the security underlying the receipt. An unsponsored facility may be established by a depositary without participation by the issuer of the security underlying the receipt. There are greater risks associated with holding unsponsored depositary receipts. For example, if the Fund holds

64

Table of Contents

an unsponsored depositary receipt, it will generally bear all of the costs of establishing the unsponsored facility. In addition, the depositary of an unsponsored facility frequently is under no obligation to distribute shareholder communications received from the issuer of the deposited security. Whether a sponsored or unsponsored facility, there is no assurance that either would pass through to the holders of the receipts voting rights with respect to the deposited securities.

In considering whether to invest in the securities of a non-U.S. company, the portfolio managers consider such factors as the characteristics of the particular company, differences between economic trends, and the performance of securities markets in the United States and other countries. The portfolio managers also consider factors relating to the general economic, governmental and social conditions of the country or countries where the company is located.

Securities transactions conducted outside the United States may not be regulated as rigorously as in the United States, may not involve a clearing mechanism and related guarantees, and are subject to the risk of governmental actions affecting trading in, or the prices of, non-U.S. securities, currencies and other instruments. The value of such positions also could be adversely affected by (i) other complex non-U.S. political, legal and economic factors, (ii) lesser availability than in the United States of data on which to make trading decisions, (iii) delays in the Fund’s ability to act upon economic events occurring in non-U.S. markets during non-business hours in the United States, (iv) the imposition of different exercise and settlement terms and procedures and the margin requirements than in the United States, and (v) lower trading volume and liquidity.

REITs

REITs are typically publicly traded corporations or trusts that invest in residential or commercial real estate. REITs generally can be divided into the following three types: (i) equity REITs which invest the majority of their assets directly in real property and derive their income primarily from rents and capital gains or real estate appreciation; (ii) mortgage REITs which invest the majority of their assets in real estate mortgage loans and derive their income primarily from interest payments; and (iii) hybrid REITs which combine the characteristics of equity REITs and mortgage REITs. The Fund can invest in common stock, preferred securities, debt securities and convertible securities issued by REITs.

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 typically holding fixed-rate securities. 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 securities 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 agreed prevailing short-term 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 security 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 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

65

Table of Contents

special purpose trust. In addition, all voting rights and decisions to be made with respect to any other rights relating to the securities 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 security 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 security 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 securities. 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 security values are falling), but tend to outperform the market of fixed rate securities 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 securities 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 security 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 termination of the trust issuing the inverse floater, the difference between the liquidation value of the securities 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.”

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

66

Table of Contents

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, dividends or interest thereon when due or that is in bankruptcy or insolvency proceedings.

Illiquid Investments

While the Fund does not currently anticipate investing to a material extent in restricted and illiquid investments (i.e., investments that are not readily marketable), the Fund may invest in illiquid investments, 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. 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 floating rate payments for fixed-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.”

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 variable rate preferred securities and other variable rate income producing securities 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 variable rate preferred securities and other variable rate income producing securities.

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.

68

Table of Contents

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.

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 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

69

Table of Contents

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.

Table of Contents

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.

When-Issued and Delayed Delivery Transactions

The Fund may buy and sell securities on a when-issued or delayed delivery basis, making payment or taking delivery at a later date, normally within 15 to 45 days of the trade date. This type of transaction may involve an element of risk because no interest accrues on the securities prior to settlement and, because securities are subject to market fluctuations, the value of the securities at time of delivery may be less (or more) than cost. A separate account of the Fund will be established with its custodian consisting of cash equivalents or liquid securities having a market value at all times at least equal to the amount of the commitment.

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 Securities and Exchange Commission’s (“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. 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. See “Risks—Portfolio Level Risks—Derivatives Risk.”

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 (the approximately six month period during which the Fund is transitioning its portfolio as the Fund’s 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 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.

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 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 securities 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 37% of the Fund’s Managed Assets, if current market conditions persist. The Fund currently intends to employ leverage through borrowings and or reverse repurchase agreements as well as the issuance of Preferred Shares within 12 months after the completion of this offering. The issuance of Preferred Shares may only be done if the Board of Trustees determines it to be in the best interests of Common Shareholders.

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

72

Table of Contents

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.

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

73

Table of Contents

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 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 37% 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 37% of the Fund’s Managed Assets, net of expenses, and the Fund’s currently projected annual interest rate and/or dividend rate on its leverage of     %.

74

Table of Contents

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.

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.

The risks have been divided into (i) Portfolio Level Risks, (ii) Fund Level Risks, and (iii) Other Risks.

Portfolio Level Risks

Preferred and Hybrid Preferred Securities Risks

Preferred and other subordinated securities rank lower than bonds and other debt instruments in a company’s capital structure and therefore will be subject to greater credit risk than those debt instruments. There are various special risks associated with investing in preferred securities, including:

76

Table of Contents

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:

77

Table of Contents

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.

Contingent Capital Securities or Contingent Convertible Securities

Contingent capital securities or contingent convertible securities (sometimes referred to as “CoCos”) have loss absorption mechanisms benefitting the issuer built into their terms. CoCos generally provide for mandatory conversion into the common stock of the issuer or a write-down of the principal amount or value of the CoCos upon the occurrence of certain “triggers.” These triggers are generally linked to regulatory capital thresholds or regulatory actions calling into question the issuing banking institution’s continued viability as a going-concern. Equity conversion or principal write-down features are tailored to the issuer and its regulatory requirements and, unlike traditional convertible securities, conversions are not voluntary.

A loss absorption mechanism trigger event for CoCos would likely be the result of, or related to, the deterioration of the issuer’s financial condition (e.g., a decrease in the issuer’s capital ratio) and status as a going concern. In such a case, with respect to CoCos that provide for conversion into common stock upon the occurrence of the trigger event, the market price of the issuer’s common stock received by the Fund will have likely declined, perhaps substantially, and may continue to decline, which may adversely affect the Fund’s NAV. Further, the issuer’s common stock would be subordinate to the issuer’s other classes of securities and therefore would worsen the Fund’s standing in a bankruptcy proceeding. In addition, because the common stock of the issuer may not pay a dividend, investors in these instruments could experience a reduced income rate, potentially to zero. In view of the foregoing, CoCos are often rated below investment grade and are subject to the risks of high yield securities.

CoCos may be subject to an automatic write-down (i.e., the automatic write-down of the principal amount or value of the securities, potentially to zero, and the cancellation of the securities) under certain circumstances, which could result in the Fund losing a portion or all of its investment in such securities. In addition, the Fund may not have any rights with respect to repayment of the principal amount of the securities that has not become due or the payment of interest or dividends on such securities for any period from (and including) the interest or dividend payment date falling immediately prior to the occurrence of such automatic write-down. An automatic write-down could also result in a reduced income rate if the dividend or interest payment is based on the security’s par value. Coupon payments on CoCos may be discretionary and may be cancelled by the issuer at any point, for any reason or may be subject to approval by the issuer’s regulator and may be suspended in the event there are insufficient distributable reserves. Certain CoCos are issued as perpetual instruments, callable at pre-determined levels only with the approval of the issuer’s regulator, thus subjecting the CoCo investor to call extension risk.

In certain scenarios, contrary to classical capital hierarchy, investors in CoCos may suffer a loss of capital ahead of equity holders or when equity holders do not. There is no guarantee that the Fund will receive a return of principal on CoCos. The Fund may lose its entire investment or may be required to accept cash or securities with a value less than its original investment. Any indication that an automatic writedown or conversion event may occur can be expected to have a material adverse effect on the market price of CoCos.

The prices of CoCos may be volatile. Additionally, the trading behavior of a given issuer’s CoCo may be strongly impacted by the trading behavior of other issuers’ CoCos, such that negative information from an unrelated CoCo may cause a decline in value of one or more CoCos held by the Fund.

78

Table of Contents

Investments in CoCos may lead to an increased industry concentration risk as such securities may be issued by a limited number of financial institutions.

Convertible Securities Risk

Convertible securities have characteristics of both equity and debt securities and, as a result, are exposed to certain additional risks that are typically associated with debt. Convertible securities generally offer lower interest or dividend yields than non-convertible securities of similar credit quality. The market values of convertible securities tend to decline as interest rates increase and, conversely, to increase as interest rates decline. However, the convertible security’s market value tends to reflect the market price of the common stock of the issuing company when that stock price is greater than the convertible security’s “conversion price.” The conversion price is defined as the predetermined price at which the convertible security could be exchanged for the associated common stock. As the market price of the underlying common stock declines, the price of the convertible security tends to be influenced more by the yield of the convertible security. However, convertible securities fall below debt obligations of the same issuer in order of preference or priority in the event of a liquidation and are typically unrated or rated lower than such debt obligations.

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.

Additionally, the Fund may be exposed to certain debt securities risks through its sukuk investments. 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.

Credit Risk

Credit risk is the risk that one or more securities in the Fund’s portfolio will decline in price, or the issuer thereof will fail to pay dividends, interest or principal when due, because the issuer of the security experiences a decline in its financial status. In general, lower-rated securities carry a greater degree of risk that the issuer will lose its ability to make dividends, interest and principal payments, which could have a negative impact on the Fund’s NAV or dividends. Credit risk is increased when a portfolio security is downgraded or the perceived

79

Table of Contents

creditworthiness of the issuer deteriorates. If a downgrade occurs, the Adviser and/or the Sub-Adviser will consider what action, including the sale of the security, is in the best interests of the Fund and its shareholders.

Debt or preferred securities held by the Fund may fail to make dividend or interest payments when due. Investments in securities below investment grade credit quality are predominantly speculative and subject to greater volatility and risk of default. Unrated securities are evaluated by Fund managers using industry data and their own analysis processes that may be similar to that of a NRSRO; however, such internal ratings are not equivalent to a national agency credit rating. Counterparty credit risk may arise if counterparties fail to meet their obligations, should the Fund hold any derivative instruments for either investment exposure or hedging purposes.

Municipal Securities Market Risk

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 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.” 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.

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 bonds 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.

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

80

Table of Contents

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.

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 dividend or interest rate than such rated investments and be subject to a greater risk of illiquidity or price changes. Less public information is typically available about unrated investments or issuers than rated investments or issuers. 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.

Restricted and Illiquid Investments Risk

Illiquid investments are investments that are not readily marketable. These investments may include restricted investments, including Rule 144A securities, which 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.

Call Risk

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

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 preferred securities or debt instruments at market interest rates that are below the portfolio’s current earnings rate. A decline in income could affect the Common Share’s market price, NAV and/or overall returns. As the average effective 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 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.

Concentration and Financial Services Sector Risk

The preferred securities market is comprised predominantly of securities issued by companies in the financial services sector. Therefore, preferred securities present substantially increased risks at times of financial turmoil, which could affect financial services companies more than companies in other sectors and industries. The Fund’s investment in securities issued by financial services companies makes the Fund more susceptible to adverse economic or regulatory occurrences affecting those companies. Concentration of investments in financial services companies includes the following risks:

The profitability of many types of financial services companies may be adversely affected in certain market cycles, including periods of rising interest rates, which may restrict the availability and increase the cost of capital, and declining economic conditions, which may cause credit losses due to financial difficulties of borrowers. Because many types of financial services companies are especially vulnerable to these economic cycles, the Fund’s investments in these companies may lose significant value during such periods.

Equity Securities Risk

Equity securities in the Fund’s portfolio may decline significantly in price over short or extended periods of time, and such declines may occur because of declines in the equity market as a whole, or because of declines in only a particular country, company, industry, or sector of the market. Given the Fund’s focus on dividend-paying securities, the Fund may, from time to time, have a greater exposure to higher dividend-yield sectors and industries than the broad equity market which would make the Fund more vulnerable to adverse developments affecting such sectors or industries.

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.

82

Table of Contents

ABS 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.

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.

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 issuer that is senior to that held by subordinated debt holders and stockholders of the issuer. 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 an issuer’s obligation to the Fund in the event of issuer default or that such collateral could be readily liquidated under such circumstances. If the terms of a senior loan do not require the issuer 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 issuer’s obligations under the senior loan.

83

Table of Contents

In the event of the bankruptcy of an issuer, 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 issuer or take other action detrimental to lenders, including the Fund. Such court action could under certain circumstances include invalidation of senior loans.

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.

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 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 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

84

Table of Contents

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.

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 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

85

Table of Contents

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, involves 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 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.

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 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

86

Table of Contents

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.

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.

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 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.

87

Table of Contents

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 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

88

Table of Contents

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.

Non-U.S. Securities Risk

Investments in securities of non-U.S. issuers involve special risks not presented by investments in securities of U.S. issuers, including the following: (i) less publicly available information about non-U.S. issuers or markets due to less rigorous disclosure or accounting standards or regulatory practices; (ii) many non-U.S. markets are smaller, less liquid and more volatile, meaning that, in a changing market, the Fund may not be able to sell its portfolio securities at times, in amounts or at prices it considers reasonable; (iii) potential adverse effects of controls on the value of the Fund’s investments; (iv) the economies of non-U.S. 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, expropriation or nationalization of the company or its assets; (vii) certain non-U.S. countries may impose restrictions on the ability of non-U.S. issuers to make payments of principal and/or interest to investors located outside the United States, and (viii) withholding and other non-U.S. taxes may decrease the Fund’s return. These risks are more pronounced to the extent that the Fund invests in securities of issuers in emerging market countries.

Economies and social and political climates in individual countries may differ unfavorably from the United States. Non-U.S. economies may have less favorable rates of growth of gross domestic product, rates of inflation, capital reinvestment, resource self-sufficiency and balance of payments positions. Many countries have experienced substantial, and in some cases extremely high, rates of inflation for many years. Unanticipated economic, political and social developments may also affect the values of the Fund’s investments and the availability to the Fund of additional investments in such countries.

LIBOR Replacement Risk

The use of the LIBOR will begin to be phased out in the near future, which 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) how, and when industry participants develop and adopt new reference rates and fallbacks for both legacy and new products and instruments held by the Fund. Accordingly, it is difficult to predict the full impact of the transition away from LIBOR until it is clearer how the Fund’s products and instruments will be impacted by this transition.

Duration Risk

Duration is the sensitivity, expressed in years, of the price of a fixed income security to changes in the general level of interest rates (or yields). Securities with longer durations tend to be more sensitive to interest rate

89

Table of Contents

(or yield) changes than securities with shorter durations. For example, if a security or portfolio has a duration of three years and interest rates increase by 1%, then the security or portfolio would decline in value by approximately 3%. Duration differs from maturity in that it considers potential changes to interest rates, and a security’s coupon payments, yield, price and par value and call features, in addition to the amount of time until the security matures. The duration of a security will be expected to change over time with changes in market factors and time to maturity. The duration of the Fund’s portfolio is not subject to any limits and therefore the portfolio may be very sensitive to interest rate changes.

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.”

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 U.S. 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 generally not expected to be 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.”

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.

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.

Table of Contents

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.

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.

When-Issued and Delayed-Delivery Transactions Risk

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

Delivery and payment for securities that have been purchased in this manner can take place a month or more after the transaction date. Such securities do not earn interest, are subject to market fluctuation, and may increase or decrease in value prior to their delivery. The purchase of securities on a when-issued or forward commitment basis may increase the volatility of the Fund’s NAV if the Fund makes such purchases while remaining substantially fully invested.

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 typically holding fixed-rate securities. See “Portfolio Composition and Other Information—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

91

Table of Contents

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 security 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 of the special purpose trust, upon termination of the trust issuing the inverse floater, the difference between the liquidation value of the securities 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 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 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 “—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.

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.

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.

93

Table of Contents

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 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,

94

Table of Contents

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 “—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 “—Portfolio Level Risks—Below Investment Grade Risk” above.

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

Table of Contents

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 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 variable rate preferred securities and other variable rate income producing securities 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

96

Table of Contents

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.

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

97

Table of Contents

the EU and the two sides entered into a transition phase, where the UK effectively remained in the EU from an economic perspective, but no longer had any political representation in the EU parliament. The transition period concluded on December 31, 2020, and EU law no longer applies in the UK. On December 30, 2020, the UK and EU signed an EU-UK Trade and Cooperation Agreement (“UK/EU Trade Agreement”), which went into effect on January 1, 2021 and sets out the foundation of the economic and legal framework for trade between the UK and EU. As the UK/EU Trade Agreement is a new legal framework, the implementation of the UK/EU Trade Agreement may result in uncertainty in its application and periods of volatility in both the UK and wider European markets. 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 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 enacted 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.

98

Table of Contents

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 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.

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. Further, the By-laws provide that a shareholder who obtains beneficial ownership of common shares in a “Control Share Acquisition” shall have the same voting rights as other Common Shares only to the extent authorized by shareholders. 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:

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

99

Table of Contents

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.

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

100

Table of Contents

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. See “—Portfolio Level Risks—Derivatives Risks.”

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 (i.e., the underwriting syndicate responsible for the initial pricing, marketing and distribution of the securities is disbanded) 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.

Investment Management and Subadvisory Agreements

Pursuant to an investment management agreement between Nuveen Fund Advisors and the Fund, the Fund will pay Nuveen Fund Advisors an annual management fee, payable monthly in arrears, in a maximum amount equal to         % of the Fund’s average daily Managed Assets. This maximum fee is equal to the sum of a fund-level fee, with breakpoints based only on the amount of assets within the Fund, and a complex-level fee, with breakpoints based upon the aggregate amount of all eligible assets of all Nuveen Funds, as described below, according to the following schedule.

Fund-Level Fee.    The fund-level fee shall be applied according to the following schedule:

Complex-Level Fee.    The effective rates of the complex-level fee at various specified complex-wide asset levels are as indicated in the following table:

103

Table of Contents

Based on eligible assets as of                 , 2021, the complex-level fee would be             % of Managed Assets, and the total annual management fee to Nuveen Fund Advisors would be             % of Managed Assets (assuming Managed Assets of $         Million or less).

In addition to Nuveen Fund Advisors’ management fee, the Fund pays all other costs and expenses of its operations, including compensation of its trustees (other than those affiliated with Nuveen), custodian, transfer agency and dividend disbursing expenses, legal fees, expenses of its independent registered accounting firm, expenses of repurchasing Common Shares, expenses of preparing, printing and distributing shareholder reports, notices, proxy statements and reports to governmental agencies, listing fees and taxes, if any. All fees and expenses are accrued daily and deducted before payment of distributions to shareholders.

Separately, pursuant to an investment sub-advisory agreement between Nuveen Fund Advisors and Nuveen Asset Management Nuveen Fund Advisors will pay Nuveen Asset Management a portfolio management fee equal to     % of the investment management fee paid on the Fund’s average daily Managed Assets.

The basis for the Board of Trustees’ initial approval of the Fund’s investment management agreement and sub-advisory agreement will be provided in the Fund’s initial shareholder report. The basis for subsequent continuations of the Fund’s investment management agreement and sub-advisory agreement will be provided in annual or semiannual reports to shareholders for the periods during which such continuations occur.

NET ASSET VALUE

The Fund’s NAV is determined as of the close of regular session trading (normally 4:00 p.m. Eastern Time) on each day the New York Stock Exchange (“NYSE”) is open for business. The Fund’s NAV is calculated by taking the market value of the Fund’s total assets, including interest or dividends accrued but not yet collected, less all liabilities, and dividing by the total number of Common Shares outstanding. The result, rounded to the nearest cent, is the NAV. All valuations are subject to review by the Fund’s Board of Trustees or its delegate.

In determining the Fund’s NAV, portfolio instruments generally are valued using prices provided by independent pricing services or obtained from other sources, such as broker-dealer quotations. Exchange-traded instruments generally are valued at the last reported sales price or official closing price on an exchange, if available. Independent pricing services typically value non-exchange-traded instruments utilizing a range of market-based inputs and assumptions. For example, when available, pricing services may utilize inputs such as benchmark yields, reported trades, broker-dealer quotes, spreads, and transactions for comparable instruments. In pricing certain instruments, the pricing services may consider information about an instrument’s issuer or market activity provided by Nuveen Fund Advisors or Nuveen Asset Management. Pricing service valuations of non-exchange-traded instruments represent the service’s good faith opinion as to what the holder of an instrument would receive in an orderly transaction for an institutional round lot position under current market conditions. It is possible that these valuations could be materially different from the value that the Fund realizes upon the sale of an instrument. Non-U.S. investments are valued in U.S. dollars.

For non-U.S. traded investments whose principal local markets close before the close of the NYSE, the Fund may adjust the local closing price based upon such factors as developments in non-U.S. markets, the performance of U.S. securities markets and the performance of instruments trading in U.S. markets that represent

104

Table of Contents

non-U.S. investments. The Fund may rely on an independent fair valuation service in making any such fair value determinations. If the Fund holds portfolio instruments that are primarily listed on non-U.S. exchanges, the value of such instruments may change on days when the Fund’s NAV is calculated.

If a price cannot be obtained from a pricing service or other pre-approved source, or if, in the judgment of Nuveen Fund Advisors, a price is unreliable, a portfolio instrument will be valued at its fair value as determined in good faith by the Board of Trustees or its appointee. Nuveen Fund Advisors may determine that a price is unreliable in various circumstances. For example, a price may be deemed unreliable if it has not changed for an identified period of time, or has changed from the previous day’s price by more than a threshold amount, and recent transactions and/or broker dealer price quotations differ materially from the price in question.

The Board of Trustees has adopted valuation procedures for the Fund and has appointed Nuveen Fund Advisors’ Valuation Committee (the “Valuation Committee”) with the day-to-day responsibility for fair value determinations. All fair value determinations made by the Valuation Committee are subject to review and ratification by the Board of Trustees. As a general principle, the fair value of a portfolio instrument is the amount that an owner might reasonably expect to receive upon the instrument’s current sale. A range of factors and analysis may be considered when determining fair value, including relevant market data, interest rates, credit considerations and/or issuer specific news. However, fair valuation involves subjective judgments and it is possible that the fair value determined for a portfolio instrument may be materially different from the value that could be realized upon the sale of that instrument. The SEC recently adopted new Rule 2a-5 under the 1940 Act, which establishes requirements for determining fair value in good faith for purposes of the 1940 Act. The Fund will comply with the new rule’s valuation requirements on or before the SEC’s compliance date in 2022.

DISTRIBUTIONS

The Fund intends to pay regular monthly distributions to Common Shareholders at a stable rate (stated in terms of a fixed cents per Common Share dividend rate) that reflects the past and projected net income performance of the Fund. The Fund currently expects that it will seek, subject to market conditions and the composition of its investment portfolio, for all or almost all of its distributions of net investment income to be treated as qualified dividend income QDI. However, not all income distributions may qualify for treatment as QDI. The tax treatment and characterization of the Fund’s distributions may vary significantly from time to time because of the varied nature of the Fund’s investments. The ultimate tax characterization of the Fund’s distributions made in a taxable year cannot be determined finally until after the end of that taxable year. None of the Fund, Nuveen Fund Advisors or Nuveen Asset Management provides tax advice to investors in the Fund or has any knowledge of a particular investor’s tax situation. As a result, investors should consult their own tax advisers when determining the tax characterization of any distributions from the Fund. See “Tax Matters.” Distributions can only be made from net investment income after paying for any expenses related to the Fund’s use of leverage, as applicable.

To help maintain more stable monthly distributions, the distribution paid by the Fund for any particular monthly period may be more or less than the amount of net income actually earned by the Fund during such period, and any such under-(or over-) distribution of income is reflected in the Fund’s NAV. The Fund’s ability to maintain a stable dividend rate will depend on a number of factors, including the costs related to the Fund’s use of leverage, if any. The net income of the Fund includes all interest income accrued on portfolio assets less all expenses of the Fund. Expenses of the Fund are accrued each day. For each year, all or substantially all of the net investment income of the Fund will be distributed. At least annually, the Fund also intends to distribute substantially all of its net capital gain (which is the excess of net long-term capital gain over net short-term capital loss) and ordinary taxable income, if any, after paying for any expenses related to the Funds use of leverage. Although it does not now intend to do so, the Board of Trustees may change the Fund’s dividend policy and the amount or timing of the distributions, based on a number of factors, including the amount of the Fund’s

105

Table of Contents

undistributed net investment income and historical and projected investment income and the amount of the expenses and dividend rates on any outstanding preferred shares and expenses and interest on borrowings.

The Fund might not distribute all or a portion of any net capital gain for a taxable year. If the Fund does not distribute all of its net capital gain for a taxable year, it will pay federal income tax on the retained gain. Provided the Fund satisfies certain requirements, each Common Shareholder of record as of the end of the Fund’s taxable year will include in income, for federal income tax purposes, as long-term capital gain, his or her share of the retained gain, will be deemed to have paid his or her proportionate share of the tax paid by the Fund on such retained gain, and will be entitled to an income tax credit or refund for that share of the tax. The Fund may treat the retained capital gains as a substitute for equivalent cash distributions. While not currently anticipated, if the Fund makes total distributions during a given calendar year in an amount that exceeds the Fund’s net investment income and net capital gain for that calendar year, the excess would generally be treated by Common Shareholders as a return of capital for tax purposes. A return of capital reduces a shareholder’s tax basis (but not below zero), which would result in more taxable gain or less taxable loss when the shareholder sells their shares. This may cause the shareholder to pay taxes even if he or she sells shares for less than the original price.

The Fund reserves the right to change its distribution policy and the basis for establishing the rate of its monthly distributions at any time upon notice to Common Shareholders, upon a determination by the Fund’s Board of Trustees that such change is in the best interests of the Fund and its Common Shareholders.

DIVIDEND REINVESTMENT PLAN

If your Common Shares are registered directly with the Fund or if you hold your Common Shares with a brokerage firm that participates in the Fund’s Dividend Reinvestment Plan (the “Plan”), your distributions, including any capital gain distributions, will automatically be reinvested in additional Common Shares under the Plan unless you request otherwise. If you elect not to participate in the Plan, or are not eligible to participate because your brokerage firm does not participate in the Plan, you will receive all distributions in cash paid by check mailed directly to you or your brokerage firm by Computershare Inc. and Computershare, as dividend paying agent. The tax consequences of a distribution are the same regardless of whether such distribution is reinvested or received in cash. See “Tax Matters.”

Under the Plan, the number of Common Shares you will receive will be determined as follows:

(1) If the NAV per Common Share is equal to or less than the market price per Common Share plus estimated per share fees (which include any applicable brokerage commissions the Plan Agent is required to (pay), the Fund will issue new shares including fractions at a price equal to the greater of (i) NAV per Common Share on that date or (ii) 95% of the market price on that date.

(2) If the NAV per Common Share exceeds the market price per Common Share plus estimated per share fees, the Plan Agent will receive the dividend or distribution in cash and will purchase Common Shares in the open market, on the              or elsewhere, for the participants’ accounts. It is possible that the market price for the Common Shares may increase before the Plan Agent has completed its purchases. Therefore, the average purchase price per share paid by the Plan Agent may exceed the market price at the time of valuation, resulting in the purchase of fewer shares than if the dividend or distribution had been paid in Common Shares issued by the Fund. The Plan Agent will use all dividends and distributions received in cash to purchase Common Shares in the open market within 30 days of the valuation date. Interest will not be paid on any uninvested cash payments. The Plan provides that if Common Shares start trading at or above NAV before the Plan Agent has completed its purchases, the Plan Agent may cease purchasing Common Shares in the open market, and may invest the uninvested portion in new shares at a price equal to the greater of (i) NAV per Common Share determined on the last business day immediately prior to the purchase date or (ii) 95% of the market price on that date.

106

Table of Contents

You may withdraw from the Plan at any time by giving written notice to the Plan Agent. If you withdraw or the Plan is terminated, you will receive whole shares in your account under the Plan and you will receive a cash payment for any fraction of a share in your account. If you wish, the Plan Agent will sell your shares and send you the proceeds, minus brokerage commissions and a $2.50 service fee.

The Plan Agent maintains all shareholders’ accounts in the Plan and gives written confirmation of all transactions in the accounts, including information you may need for tax records. Common Shares in your account will be held by the Plan Agent in non-certificated form. Any proxy you receive will include all Common Shares you have received under the Plan.

There is no brokerage charge for reinvestment of your dividends or distributions in Common Shares. However, all participants will pay a pro rata share of brokerage commissions incurred by the Plan Agent when it makes open market purchases.

Automatically reinvesting dividends and distributions does not mean that you do not have to pay income taxes due upon receiving dividends and distributions.

As noted above, if you hold your Common Shares with a brokerage firm that does not participate in the Plan, you will not be able to participate in the Plan and any dividend reinvestment may be effected on different terms than those described above. Consult your financial advisor for more information.

The Fund reserves the right to amend or terminate the Plan if in the judgment of the Board of Trustees the change is warranted. There is no direct service charge to participants in the Plan; however, the Fund reserves the right to amend the Plan to include a service charge payable by the participants. Additional information about the Plan may be obtained from Computershare, P.O. Box 505000, Louisville, Kentucky, 40233-5000, (800) 257-8787.

DESCRIPTION OF SHARES AND DEBT

Common Shares

The Fund’s Declaration of Trust authorizes the issuance of an unlimited number of Common Shares. The Common Shares being offered have a par value of $.01 per share and have equal rights to the payment of dividends and the distribution of assets upon liquidation of the Fund. The Common Shares being offered will, when issued, be fully paid and, subject to matters discussed under “Certain Provisions in the Declaration of Trust and By-Laws,” non-assessable, and will have no preemptive or conversion rights, except as the Board of Trustees may otherwise determine, or rights to cumulative voting. The Declaration of Trust provides that each whole Common Share shall be entitled to one vote as to any matter on which it is entitled to vote and each fractional Common Share shall be entitled to a proportionate fractional vote. If the Fund issues Preferred Shares, the Common Shareholders will not be entitled to receive any cash distributions from the Fund unless all accrued dividends on Preferred Shares have been paid, and unless asset coverage (as defined in the 1940 Act) with respect to Preferred Shares would be at least 200% after giving effect to the distributions. The Fund pays monthly dividends, typically on the first business day of the following month.

It is anticipated that the Fund’s Common Shares will be approved for listing on the             , subject to notice of issuance, under the ticker symbol “            .” The Fund intends to hold annual meetings of shareholders so long as the Common Shares are listed on a national securities exchange and such meetings are required as a condition to such listing. The Fund will not issue share certificates.

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

107

Table of Contents

NAV. Shares of closed-end investment companies like the Fund have, during some periods, traded at prices higher than NAV and, during other periods, have traded at prices lower than NAV. Because the market value of the Common Shares may be influenced by such factors as dividend levels (which are in turn affected by expenses), dividend stability, NAV, relative demand for and supply of such shares in the market, general market and economic circumstances, and other factors beyond the Fund’s control, the Fund cannot guarantee you that Common Shares will trade at a price equal to or higher than NAV in the future. See “Repurchase of Common Shares; Conversion to Open-End Fund” in this prospectus and in the SAI.

The following provides information about the Fund’s outstanding Common Shares as of             , 2021:

Preferred Shares

The Fund’s Declaration of Trust authorizes the issuance of an unlimited number of Preferred Shares in one or more classes or series, with rights as determined by the Board of Trustees, by action of the Board of Trustees without the approval of the Common Shareholders. The terms of any Preferred Shares that may be issued by the Fund may be the same as, or different from, the terms described below, subject to applicable law and the Declaration of Trust.

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

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

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

Liquidation Preference.    In the event of any voluntary or involuntary liquidation, dissolution or winding up of the affairs of the Fund, holders of Preferred Shares would be entitled to receive a preferential liquidating distribution (expected to equal the original purchase price per share plus accumulated and unpaid dividends

108

Table of Contents

thereon, whether or not earned or declared) before any distribution of assets is made to Common Shareholders. After payment of the full amount of the liquidating distribution to which they are entitled, holders of Preferred Shares will not be entitled to any further participation in any distribution of assets by the Fund. A consolidation or merger of the Fund with or into another entity or a sale of all or substantially all of the assets of the Fund shall not be deemed to be a liquidation, dissolution or winding up of the Fund.

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

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

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

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

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

Senior Securities Representing Indebtedness

The Fund’s Declaration of Trust authorizes the Fund, without approval of the Common Shareholders, to borrow money. In this connection, the Fund may issue notes or other evidence of indebtedness (including bank borrowings or commercial paper) and may secure any such debt by mortgaging, pledging or otherwise subjecting as security the Fund’s assets. Under the requirements of the 1940 Act, the Fund, immediately after issuing any such senior securities debt, must have an “asset coverage” of at least 300%. With respect to any such 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. Certain types of debt may result in the Fund being subject to certain restrictions imposed by guidelines of one or more rating agencies which may issue ratings for commercial paper or notes issued by the Fund. Such restrictions may be more stringent than those imposed by the 1940 Act.

The rights of lenders to the Fund to receive interest on and repayment of principal of any such debt will be senior to those of the Common Shareholders, and the terms of any such debt may contain provisions which limit certain activities of the Fund, including the payment of dividends to Common Shareholders in certain circumstances. Further, the 1940 Act does (in certain circumstances) grant to the lenders to the Fund certain voting rights in the event of default in the payment of interest on or repayment of principal. Any debt will likely be ranked senior or equal to all other existing and future debt of the Fund.

Should the Fund have outstanding any “senior securities representing indebtedness,” the Fund may not purchase, redeem or acquire any of its Common Shares or Preferred Shares unless at the time of such purchase, redemption, or acquisition, the asset coverage of such senior securities representing indebtedness pursuant to the 1940 Act (determined after deducting the acquisition price of such Common or Preferred Shares) is at least 300%. Additionally, the Fund will generally not be permitted to declare dividends or other distributions on its Common Shares unless, at the time of such declaration or distribution, the asset coverage applicable to such senior securities representing indebtedness pursuant to the 1940 Act (determined after deducting the dividend or distribution amount) is at least 300%. Further, the 1940 Act (in certain circumstances) grants to the holders of such senior securities representing indebtedness (1) the right to declare a default, and (2) certain voting rights, in the event that specified asset coverage levels on such senior debt securities are not maintained. Specifically, in accordance with Section 18 of the 1940 Act, it shall be deemed an event of default if the asset coverage of such senior debt securities falls below 100% on the last business day of each month for 24 consecutive calendar months. In addition, senior debt security holders will be permitted to elect at least a majority of the Fund’s trustees if the asset coverage of such senior debt securities falls below 100% on the last business day of each month for a 12 calendar month period. These voting rights will continue until such asset coverage equals at least 110% on the last business day of each month for three consecutive calendar months. The provisions described in this paragraph do not apply, however, to bank or other privately arranged debt that is not intended to be publicly distributed.

Inter-Fund Borrowing and Lending.    The SEC has granted an exemptive order permitting the Nuveen registered open-end and closed-end funds, including the Fund, to participate in an inter-fund lending facility whereby those funds may directly lend to and borrow money from each other for temporary purposes (e.g., to satisfy redemption requests or when a sale of securities “fails,” resulting in an unanticipated cash shortfall) (the “Inter-Fund Program”). The closed-end Nuveen funds will participate only as lenders, and not as borrowers, in the Inter-Fund Program because such closed-end funds rarely, if ever, need to borrow cash to meet redemptions. The Inter-Fund Program is subject to a number of conditions, including, among other things, the requirements that (1) no fund may borrow or lend money through the Inter-Fund Program unless it receives a more favorable interest rate than is typically available from a bank or other financial institution for a comparable transaction; (2) no fund may borrow on an unsecured basis through the Inter-Fund Program unless the fund’s outstanding borrowings from all sources immediately after the inter-fund borrowing total 10% or less of its total assets; provided that if the borrowing fund has a secured borrowing outstanding from any other lender, including but not limited to another fund, the inter-fund loan must be secured on at least an equal priority basis with at least an

110

Table of Contents

equivalent percentage of collateral to loan value; (3) if a fund’s total outstanding borrowings immediately after an inter-fund borrowing would be greater than 10% of its total assets, the fund may borrow through the inter-fund loan on a secured basis only; (4) no fund may lend money if the loan would cause its aggregate outstanding loans through the Inter-Fund Program to exceed 15% of its net assets at the time of the loan; (5) a fund’s inter-fund loans to any one fund shall not exceed 5% of the lending fund’s net assets; (6) the duration of inter-fund loans will be limited to the time required to receive payment for securities sold, but in no event more than seven days; and (7) each inter-fund loan may be called on one business days’ notice by a lending fund and may be repaid on any day by a borrowing fund. In addition, a Nuveen fund may participate in the Inter-Fund Program only if and to the extent that such participation is consistent with the fund’s investment objective and investment policies. The Board of Trustees of the Nuveen Funds is responsible for overseeing the Inter-Fund Program. The limitations detailed above and the other conditions of the SEC exemptive order permitting the Inter-Fund Program are designed to minimize the risks associated with Inter-Fund Program for both the lending fund and the borrowing fund. However, no borrowing or lending activity is without risk. When a fund borrows money from another fund, there is a risk that the loan could be called on one day’s notice or not renewed, in which case the fund may have to borrow from a bank at a higher rate or take other actions to payoff such loan if an inter-fund loan is not available from another fund. Any delay in repayment to a lending fund could result in a lost investment opportunity or additional borrowing costs.

CERTAIN PROVISIONS IN THE DECLARATION OF TRUST AND BY-LAWS

General

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

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

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

Anti-Takeover Provisions.    The Declaration of Trust and By-laws include provisions that could limit the ability of other entities or persons to acquire control of the Fund or to convert the Fund to open-end status. The By-laws require the Board of Trustees be divided into three classes with staggered terms. See “Management of the Fund” in the SAI. This provision of the By-laws could delay for up to two years the replacement of a majority of the Board of Trustees. If Preferred Shares are issued, holders of Preferred Shares, voting as a separate class, will be entitled to elect two of the Fund’s trustees. In addition, the Declaration of Trust requires a vote by holders of at least two-thirds of the Common Shares and, if issued, Preferred Shares, voting together as a single class, except as described below, to authorize (1) a conversion of the Fund from a closed-end to an open-end investment company, (2) a merger or consolidation of the Fund, or a series or class of the Fund, with any

111

Table of Contents

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

The By-laws of the Fund provide that a shareholder who obtains beneficial ownership of common shares in a “Control Share Acquisition” shall have the same voting rights as other holders of Common Shares only to the extent authorized by shareholders. Such authorization shall require the affirmative vote of the holders of a majority (more than 50%) of the shares of the Fund entitled to vote in the election of trustees excluding interested shares. Interested shares include shares held by Fund officers and any person who has acquired Common Shares in a Control Share Acquisition (the “Control Share Provisions”). The By-laws define a “Control Share Acquisition,” subject to various conditions and exceptions, generally to mean an acquisition of Common Shares that would give the beneficial owner, upon the acquisition of such shares, the ability to exercise voting power, but for the Control Share Provisions, in the election of trustees in any one of the following ranges: (i) one-tenth or more, but less than one-fifth of all voting power; (ii) one-fifth or more, but less than one-third of all voting power; (iii) one-third or more, but less than a majority of all voting power; or (iv) a majority or more of all voting power. For this purpose, all Common Shares acquired by a person within ninety days before or after the date on which such person acquires shares that result in a Control Share Acquisition, and all Common Shares acquired by such person pursuant to a plan to make a Control Share Acquisition, shall be deemed to have been acquired in the same Control Share Acquisition. Subject to various conditions and procedural requirements, including the delivery of a “Control Share Acquisition Statement” to the Fund setting forth certain required information, a shareholder who obtains or proposes to obtain beneficial ownership of common shares in a Control Share Acquisition generally may request a vote of shareholders to approve the authorization of voting rights of such shareholder with respect to such shares.

The provisions of the Declaration of Trust and By-laws described above 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 by discouraging a third party from seeking to obtain control of the Fund in a tender offer or similar transaction. The overall effect of these provisions is to render more difficult the accomplishment of a merger or the assumption of control by a third party. They provide, however, the advantage of potentially requiring persons seeking control of the Fund to negotiate with its management regarding the price

112

Table of Contents

to be paid and facilitating the continuity of the Fund’s investment objective and policies. The Fund’s Board of Trustees has considered the foregoing anti-takeover provisions and concluded that they are in the best interests of the Fund and its Common Shareholders.

Term.    The Declaration of Trust provides that the Fund will have a limited period of existence and will terminate as of the Stated Termination Date; provided that the Board of Trustees may, in its sole discretion and without any action by the shareholders of the Fund, extend the Fund’s term for up to two one year periods furthermore, notwithstanding the foregoing, if the Board of Trustees determines to cause the Fund to conduct an Eligible Tender Offer, 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, provide that the Fund may continue without limitation of time, subject to the terms and conditions described herein. Unless the Fund’s existence is continued without limitation of time as described herein on or before the Termination Date, the Fund will cease its 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 Declaration of Trust provides that the Fund, or any class or series thereof, may be terminated at any time by the Board of Trustees by notice to the shareholders without a vote of the shareholders of the Fund.

The Declaration of Trust provides that an Eligible Tender Offer is a tender offer by the Fund to all holders of outstanding common shares as of a date within 18 months preceding the Termination Date. If the tender offer is completed, Common 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. The Declaration of Trust provides that, if the number of properly tendered Common Shares would result in the Fund exceeding the Termination Threshold, then the Board of Trustees may determine to provide that the Fund may continue without limitation of time. The Declaration of Trust provides that if net assets of the Fund would be less than the Termination Threshold following the completion of the Eligible Tender Offer, the tender offer will not be completed, no Common Shares will be purchased and the Fund will terminate as of the Termination Date.

Procedural Requirements on Derivative Actions, Exclusive Jurisdiction and Jury Trial Waiver

The By-laws of the Fund, dated as of October 5, 2020 and effective with respect to the Fund as of May 26, 2021, contain certain provisions affecting potential shareholder claims against the Fund, including procedural requirements for derivative actions, an exclusive forum provision, and the waiver of shareholder rights to a jury trial. Massachusetts is considered a “universal demand” state, meaning that under Massachusetts corporate law a shareholder must make a demand on the company before bringing a derivative action (i.e., a lawsuit brought by a shareholder on behalf of the company). The By-laws of the Fund provide detailed procedures for the bringing of derivative actions by shareholders which are modeled on the substantive provisions of the Massachusetts corporate law derivative demand statute. The procedures are intended to permit legitimate inquiries and claims while avoiding the time, expense, distraction, and other harm that can be caused to the Fund or its shareholders as a result of spurious shareholder demands and derivative actions. Among other things, these procedures:

113

Table of Contents

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

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

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

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

REPURCHASE OF COMMON SHARES; CONVERSION TO  OPEN-END FUND

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

If the Fund converted to an open-end investment company, the Common Shares would no longer be listed on the              or elsewhere and it would likely have to significantly reduce any leverage it is then employing, which may require a repositioning of its investment portfolio, which may in turn generate substantial transaction costs, which would be borne by Common Shareholders, and may adversely affect Fund performance and Fund distributions. In contrast to a closed-end investment company, shareholders of an open-end investment company may require the company to redeem their shares at any time (except in certain circumstances as authorized by the 1940 Act or the rules thereunder) at their NAV, less any redemption charge that is in effect at the time of redemption. The Fund currently expects that any such redemptions would be made in cash. The Fund may charge sales or redemption fees upon conversion to an open-end fund. In order to avoid maintaining large cash positions

114

Table of Contents

or liquidating favorable investments to meet redemptions, open-end investment companies typically engage in a continuous offering of their shares. Open-end investment companies are thus subject to periodic asset in-flows and out-flows that can complicate portfolio management. The Board of Trustees may at any time propose conversion of the Fund to an open-end investment company depending upon its judgment as to the advisability of such action in light of circumstances then prevailing. See “Repurchase of Common Shares; Conversion to Open-End Fund” in the SAI for a discussion of the voting requirements applicable to the conversion of the Fund to an open-end investment company.

Before deciding whether to take any action if the Common Shares trade below NAV, the Board of Trustees would consider all relevant factors, including the extent and duration of the discount, the liquidity of the Fund’s portfolio, the impact of any action that might be taken on the Fund or its shareholders, and market considerations. Based on these considerations, even if the Fund’s shares should trade at a discount, the Board of Trustees may determine that, in the interest of the Fund and its shareholders, no action should be taken. See “Repurchase of Common Shares; Conversion to Open-End Fund” in the SAI for a further discussion of possible action to reduce or eliminate such discount to NAV.

TAX MATTERS

The following discussion of U.S. federal income tax matters is based on the advice of Stradley Ronon Stevens & Young, LLP, counsel to the Fund.

The discussions below and certain disclosure in the SAI provide general U.S. federal income tax information related to an investment in the Common Shares. Because tax laws are complex and often change, you should consult your tax advisor about the tax consequences of an investment in the Fund. The following tax discussion assumes that you are a U.S. Common Shareholder (as defined under “Tax Matters” in the SAI) and that you hold the Common Shares as a capital asset (generally, property held for investment).

Prospective investors should consult their own tax advisers with regard to the U.S. federal tax consequences of the purchase, ownership, and disposition of Common Shares, as well as the tax consequences arising under the laws of any state, local, foreign, or other taxing jurisdiction.

The discussion below does not represent a detailed description of the U.S. federal income tax considerations relevant to special classes of taxpayers including, without limitation, financial institutions, insurance companies, taxpayers subject to the alternative minimum tax, a partnership or other entity treated as a pass-through entity for U.S. federal income tax purposes, U.S. Common Shareholders whose “functional currency” is not the U.S. dollar, tax-exempt organizations, a controlled foreign corporation or a passive foreign investment company, dealers in securities or currencies, traders in securities or commodities that elect mark-to-market treatment, or persons that will hold Common Shares as a position in a “straddle,” “hedge” or as part of a “constructive sale” for U.S. federal income tax purposes.

If a partnership (or an entity treated as a partnership for U.S. federal income tax purposes) holds Common Shares, the tax treatment of a partner in the partnership generally will depend upon the status of the partner and the activities of the partnership. Partnerships that hold Common Shares should consult their tax advisors about the U.S. federal income tax considerations to their partners of the purchase, ownership and disposition of Common Shares.

The Fund intends to elect to be treated and to qualify each year as a RIC under Subchapter M of the Code. In order to qualify as a RIC, the Fund must satisfy certain requirements regarding the sources of its income, the diversification of its assets and the distribution of its income. As a RIC, the Fund is not expected to be subject to U.S. federal income tax on the portion of its investment company taxable income and net recognized capital gains that it distributes to Common Shareholders.

115

Table of Contents

Although the Fund primarily invests in securities whose income is subject to U.S. federal income tax, the Fund also will invest in tax-exempt municipal securities as described above. Although the Fund anticipates investing a portion of its assets in municipal securities, the Fund will not satisfy the requirements of the Code to pay exempt-interest dividends to Common Shareholders. Exempt-interest dividends distributed by the Fund generally would be excluded from gross income for U.S. federal income tax purposes. To be eligible to pay exempt interest dividends the Fund would need to satisfy a number of requirements including that at least 50 percent of the value of the Fund’s total assets, at the close of each quarter of its taxable year, must consist of qualifying tax-exempt municipal securities. The Fund does not expect to satisfy this requirement. Thus, substantially all of the Fund’s dividends paid to you will be taxable dividends. Additionally, because of the Fund’s investment objective, it generally does not expect to distribute dividends eligible for qualified dividend income treatment or the dividends received deduction. In addition to ordinary dividends, the Fund also may distribute to its Common Shareholders amounts that are treated as long-term capital gain. Taxable distributions are taxable whether or not such distributions are received in cash or reinvested in the Fund. Capital gain distributions are generally taxable at rates applicable to long-term capital gains regardless of how long a Common Shareholder has held his or her Common Shares. Long-term capital gains for noncorporate shareholders are currently taxable at a maximum rate of 20%.

As a RIC, the Fund will not be subject to U.S. federal income tax in any taxable year on income or gains that it timely distributes to shareholders. As described in “Distributions” above, the Fund may retain for investment a portion of its net investment income and some (or all) of its net capital gain. If the Fund retains any net capital gain or investment company taxable income, it generally will be subject to tax at the corporate income tax rate on the amount retained. If the Fund retains any net capital gain, it may report the retained amount as undistributed capital gains as part of its annual reporting to its shareholders who (i) will be required to include in income for U.S. federal income tax purposes, as long-term capital gain, their share of such undistributed amount; (ii) will be entitled to credit their proportionate shares of the tax paid by the Fund on such undistributed amount against their U.S. federal income tax liabilities, if any; and (iii) will be entitled to claim refunds to the extent the credit exceeds such liabilities. For U.S. federal income tax purposes, the tax basis of Common Shares owned by a Common Shareholder will be increased by an amount equal to the difference between the amount of undistributed capital gains included in the shareholder’s gross income and the tax deemed paid by the Common Shareholder under clause (ii) of the preceding sentence.

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

Each Common Shareholder will receive an annual statement summarizing the shareholder’s dividend and capital gains distributions (including net capital gains credited to the Common Shareholder but retained by the Fund) after the close of the Fund’s taxable year.

The sale or exchange of Common Shares, including in connection with the Fund’s final distribution to shareholders on or about the Termination Date, normally will result in capital gain or loss to Common Shareholders in an amount equal to the difference between the U.S. Common Shareholder’s adjusted tax basis in the shares and the amount realized from the sale or other disposition. Generally a shareholder’s gain or loss will be long-term capital gain or loss if the Common Shares have been held for more than one year. Present law taxes both long-term and short-term capital gains of corporations at the same rates applicable to ordinary income. For non-corporate taxpayers, however, long-term capital gains are currently taxed at a maximum rate of 20%, while short-term capital gains and other ordinary income are currently taxed at ordinary income rates. If a Common Shareholder sells or otherwise disposes of Common Shares before holding them for more than six months, any loss on the sale or disposition will be treated as a long-term capital loss to the extent of any net capital gains distributed to the Common Shareholder (including any net capital gains credited to them but retained by the Fund). Any loss realized on a sale or exchange of Common Shares will be disallowed to the extent those Common Shares are replaced by other substantially identical shares within a period of 61 days beginning 30 days

116

Table of Contents

before and ending 30 days after the date of disposition of the original Common Shares. In that event, the basis of the replacement shares will be adjusted to reflect the disallowed loss.

The Fund may be subject to foreign taxes, which could reduce the amount of its distributions. If more than 50% of the Fund’s assets are invested in foreign securities at the end of a year, the Fund will be eligible to make an election permitting shareholders to claim a credit or deduction for their pro rata share of foreign taxes paid by the Fund. If it makes this election, the Fund may report more taxable income to Common Shareholders than it actually distributes. There can be no assurance that the Fund will be eligible to pass through foreign tax credits in any given year. It is not anticipated that the Fund will invest in foreign securities to the extent necessary to meet the above 50% threshold to pass through the foreign taxes it pays to shareholders.

The Fund may be required to “backup” withhold U.S. federal income tax at the current rate of 24% of all taxable distributions payable to Common Shareholders who fail to provide the Fund with their correct taxpayer identification number or to make required certifications, or if the Common Shareholders have been notified by the Internal Revenue Service (“IRS”) that they are subject to backup withholding. Backup withholding is not an additional tax; rather, it is a way in which the IRS ensures it will collect taxes otherwise due. Any amounts withheld may be credited against a shareholder’s U.S. federal income tax liability provided the required information is timely furnished to the IRS.

The Fund may invest in other securities the U.S. federal income tax treatment of which is uncertain or subject to re-characterization by the IRS. To the extent the tax treatment of such securities or their income differs from the tax treatment expected by the Fund, it could affect the timing or character of income recognized by the Fund, requiring the Fund to purchase or sell securities, or otherwise change its portfolio, in order to comply with the tax rules applicable to RICs under the Code. Common Shareholders may be subject to state, local and foreign taxes on their Fund distributions. Shareholders are advised to consult their own tax advisers with respect to the particular consequences to them of an investment in the Fund.

UNDERWRITERS

Under the terms and subject to the conditions in an underwriting agreement dated the date of this prospectus, the Underwriters named below, for whom                      are acting as representatives (collectively, the “Representatives”), have severally agreed to purchase, and the Fund has agreed to sell to them, the number of Common Shares indicated below.

The Underwriters are offering the Common Shares subject to their acceptance of the shares from the Fund and subject to prior sale. The underwriting agreement provides that the obligations of the several Underwriters to pay for and accept delivery of the Common Shares offered by this prospectus are subject to the approval of certain legal matters by their counsel and to certain other conditions. The Underwriters are obligated to take and pay for all of the Common Shares offered by this prospectus if any such shares are taken. However, the Underwriters are not required to take or pay for the Common Shares covered by the Underwriters’ over-allotment option described below.

The Underwriters initially propose to offer part of the Common Shares directly to the public at the public offering price listed on the cover page of this prospectus and part to certain dealers at a price that represents a concession not in excess of $         per Common Share under the public offering price. Investors must pay for any Common Shares purchased on or before                         , 2021.

The Fund has granted to the Underwriters an option, exercisable for 45 days from the date of this prospectus, to purchase up to                         additional Common Shares at the public offering price listed on the cover page of this prospectus. The Underwriters may exercise this option solely for the purpose of covering over-allotments, if any, made in connection with the offering of the Common Shares offered by this prospectus. To the extent the option is exercised, each Underwriter will become obligated, subject to certain conditions, to purchase about the same percentage of the additional Common Shares as the number listed next to the Underwriter’s name in the preceding table bears to the total number of Common Shares listed next to the names of all Underwriters in the preceding table.

The following table shows the per share and total public offering price, underwriting discounts and commissions (sales load) and proceeds to the Fund. These amounts are shown assuming both no exercise and full exercise of the Underwriters’ option to purchase up to an additional                         Common Shares.
