SEMI-ANNUAL SHAREHOLDER REPORT FOR THE PERIOD ENDING JUNE 30, 2025

The Nuveen S&P 500 Buy-Write Income Fund (BXMX), Nuveen Dow 30SM Dynamic Overwrite Fund (DIAX), Nuveen S&P 500 Dynamic Overwrite Fund (SPXX), Nuveen Nasdaq 100 Dynamic Overwrite Fund (QQQX) and Nuveen Core Equity Alpha Fund (JCE) seek to offer attractive cash flow to their shareholders, by converting the expected long-term total return potential of the Funds’ portfolio of investments into regular quarterly distributions. Following is a discussion of the Managed Distribution Policy the Funds use to achieve this.

Each Fund pays quarterly common share distributions that seek to convert the Fund’s expected long-term total return potential into regular cash flow. As a result, the Funds’ regular common share distributions (presently $0. 2725 , $0.3010, $0.3375, $0.5600, $0.3200 per share, respectively) may be derived from a variety of sources, including:

• Net investment income consisting of regular interest and dividends

• Realized capital gains or,

• Possibly, returns of capital representing in certain cases unrealized capital appreciation.

Such distributions are sometimes referred to as “managed distributions.” Each Fund seeks to establish a distribution rate that roughly corresponds to the Adviser’s projections of the total return that could reasonably be expected to be generated by each Fund over an extended period of time. The Adviser may consider many factors when making such projections, including, but not limited to, long-term historical returns for the asset classes in which each Fund invests. As portfolio and market conditions change, the distribution amount and distribution rate on the Common Shares under the Funds’ Managed Distribution Policy could change.

When it pays a distribution, each Fund provides holders of its Common Shares a notice of the estimated sources of the Fund’s distributions (i.e., what percentage of the distributions is estimated to constitute ordinary income, short-term capital gains, long-term capital gains, and/or a non-taxable return of capital) on a year-to-date basis. It does this by posting the notice on its website (www.nuveen.com/cef), and by sending it in written form.

You should not draw any conclusions about the Funds’ investment performance from the amount of this distribution or from the terms of the Funds’ Managed Distribution Policy. The Funds’ actual financial performance will likely vary from month-to-month and from year-to-year, and there may be extended periods when the distribution rate will exceed the Funds’ actual total returns. The Managed Distribution Policy provides that the Board may amend or terminate the Policy at any time without prior notice to Fund shareholders. There are presently no reasonably foreseeable circumstances that might cause each Fund to terminate its Managed Distribution Policy.

Common Share Information

DISTRIBUTION INFORMATION

The following 19(a) Notice presents the Funds’ most current distribution information as of May 31, 2025 as required by certain exempted regulatory relief the Funds have received.

Because the ultimate tax character of your distributions depends on the Funds’ performance for its entire fiscal year (which is the calendar year for the Funds) as well as certain fiscal year-end (FYE) tax adjustments, estimated distribution source information you receive with each distribution may differ from the tax information reported to you on your Funds’ IRS Form 1099 statement.

Each Fund makes regular cash distributions to shareholders of stated dollar amount per share. Subject to approval and oversight by the Board of Trustees, the Fund seeks to maintain a stable distribution level designed to deliver the long-term return potential of each Fund’s investment strategy through regular distributions (a “Managed Distribution Program”). The practice of maintaining a stable distribution level had no material effect on each Fund’s investment strategy during the most recent fiscal period and is not expected to have such an effect in future periods, however, distributions in excess of Fund returns will cause its NAV per share to erode. For additional information, refer to the distribution information section below and in the Notes to Financial Statements herein.

DISTRIBUTION INFORMATION - AS OF MAY 31, 2025

This notice provides shareholders with information regarding fund distributions, as required by current securities laws. You should not draw any conclusions about the Funds’ investment performance from the amount of this distribution or from the terms of the Funds’ Managed Distribution Policy.

The following table provides estimates of the Funds’ distribution sources, reflecting year-to-date cumulative experience through the month-end prior to the latest distribution. The Funds attribute these estimates equally to each regular distribution throughout the year. Consequently, the estimated information as of the specified month-end shown below is for the current distribution, and also represents an updated estimate for all prior months in the year. For BXMX, SPXX, QQQX, and JCE it is estimated that the Funds have distributed more than their income and net realized capital gains; therefore, a portion of the distributions may be (and is shown below as being estimated to be) a return of capital. A return of capital may occur, for example, when some or all of the money that you invested in the Fund is paid back to you. A return of capital distribution does not necessarily reflect the Fund’s investment performance and should not be confused with “yield” or “income.”

The amounts and sources of distributions reported in this notice are only estimates and are not being provided for tax reporting purposes. The actual amounts and sources of the amounts for tax reporting purposes will depend upon the Funds’ investment experience during the remainder of its fiscal year and may be subject to changes based on tax regulations. Each Fund will send you a Form 1099-DIV for the calendar year that will tell you how to report these distributions for federal income tax purposes. More details about the Funds’ distributions and the basis for these estimates are available on www.nuveen.com/cef.

(a) Based on average shares outstanding.

(b) Total Return Based on Common Share NAV is the combination of changes in common share NAV, reinvested distributions at Common Share NAV, if any. The last distribution declared in the period, which is typically paid on the first business day of the following month, is assumed to be reinvested at the ending NAV. The actual reinvest price for the last distribution declared in the period may often be based on the Fund’s market price (and not its NAV), and therefore may be different from the price used in the calculation. Total returns are not annualized.

Total Return Based on Common Share Price is the combination of changes in the market price per share and the effect of reinvested distributions, if any, at the average price paid per share at the time of reinvestment. The last distribution declared in the period, which is typically paid on the first business day of the following month, is assumed to be reinvested at the ending market price. The actual reinvestment for the last distribution declared in the period may take place over several days, and in some instances may not be based on the market price, so the actual reinvestment price may be different from the price used in the calculation. Total returns are not annualized.

The last distribution declared in the period, which is typically paid on the first business day of the following month, is assumed to be reinvested at the ending NAV. The actual reinvest price for the last distribution declared in the period may often be based on the Fund’s market price (and not its NAV), and therefore may be different from the price used in the calculation. Total returns are not annualized.

Total Return Based on Common Share Price is the combination of changes in the market price per share and the effect of reinvested distributions, if any, at the average price paid per share at the time of reinvestment. The last distribution declared in the period, which is typically paid on the first business day of the following month, is assumed to be reinvested at the ending market price. The actual reinvestment for the last distribution declared in the period may take place over several days, and in some instances may not be based on the market price, so the actual reinvestment price may be different from the price used in the calculation. Total returns are not annualized.

1. General Information

Fund Information: The funds covered in this report and their corresponding New York Stock Exchange (“NYSE”) or Nasdaq National Market (“Nasdaq”) symbols are as follows (each a “Fund” and collectively, the “Funds”):

• Nuveen S&P 500 Buy-Write Income Fund (BXMX)

• Nuveen Dow 30SM Dynamic Overwrite Fund (DIAX)

• Nuveen S&P 500 Dynamic Overwrite Fund (SPXX)

• Nuveen Nasdaq 100 Dynamic Overwrite Fund (QQQX)

• Nuveen Core Equity Alpha Fund (JCE)

The Funds are registered under the Investment Company Act of 1940 (the “1940 Act”), as amended, as closed-end management investment companies. Shares of BXMX, DIAX, SPXX and JCE are traded on the NYSE while shares of QQQX are traded on the Nasdaq. BXMX, DIAX, SPXX, QQQX and JCE were organized as Massachusetts business trusts on July 23, 2004, May 20, 2014, November 11, 2004, May 20, 2014 and January 9, 2007, respectively.

Current Fiscal Period: The end of the reporting period for the Funds is June 30, 2025, and the period covered by these Notes to Financial Statements is the six months ended June 30, 2025 (the “current fiscal period”).

Investment Adviser and Sub-Adviser: The Funds’ investment adviser is Nuveen Fund Advisors, LLC (the “Adviser”), a subsidiary of Nuveen, LLC (“Nuveen”). Nuveen is the investment management arm of Teachers Insurance and Annuity Association of America (TIAA). The Adviser has overall responsibility for management of the Funds, oversees the management of the Funds’ portfolios, manages the Funds’ business affairs and provides certain clerical, bookkeeping and other administrative services, and, if necessary, asset allocation decisions. The Adviser has entered into sub- advisory agreements with Gateway Investment Advisers, LLC (“Gateway”), under which Gateway manages BXMX’s investment portfolio and Nuveen Asset Management, LLC (“NAM”), a subsidiary of the Adviser, under which NAM manages the investment portfolios of DIAX, SPXX, QQQX and JCE.

2. Significant Accounting Policies

The accompanying financial statements were prepared in accordance with accounting principles generally accepted in the United States of America (“U.S. GAAP”), which may require the use of estimates made by management and the evaluation of subsequent events. Actual results may differ from those estimates. Each Fund is an investment company and follows accounting guidance in the Financial Accounting Standards Board (“FASB”) Accounting Standards Codification 946, Financial Services – Investment Companies. The net asset value (“NAV”) for financial reporting purposes may differ from the NAV for processing security and shareholder transactions. The NAV for financial reporting purposes includes security and shareholder transactions through the date of the report. Total return is computed based on the NAV used for processing security and shareholder transactions. The following is a summary of the significant accounting policies consistently followed by the Funds.

Compensation: The Funds pay no compensation directly to those of its officers, all of whom receive remuneration for their services to the Funds from the Adviser or its affiliates. The Funds’ Board of Trustees (the “Board”) has adopted a deferred compensation plan for independent trustees that enables trustees to elect to defer receipt of all or a portion of the annual compensation they are entitled to receive from certain Nuveen-advised funds. Under the plan, deferred amounts are treated as though equal dollar amounts had been invested in shares of select Nuveen-advised funds.

Distributions to Common Shareholders: Distributions to common shareholders are recorded on the ex-dividend date. The amount, character and timing of distributions are determined in accordance with federal income tax regulations, which may differ from U.S. GAAP.

The Funds’ distribution policy, which may be changed by the Board, is to make regular monthly cash distributions to holders of their common shares (stated in terms of a fixed cents per common share dividend distributions rate which may be set from time to time). Each Fund intends to distribute all or substantially all of its net investment income each year through its regular monthly distribution and to distribute realized capital gains at least annually. In addition, in any monthly period, to maintain its declared per common share distribution amount, a Fund may distribute more or less than its net investment income during the period. In the event a Fund distributes more than its net investment income during any yearly period, such distributions may also include realized gains and/or a return of capital. To the extent that a distribution includes a return of capital the NAV per share may erode.

Foreign Currency Transactions and Translation: To the extent that the Funds invest in securities and/or contracts that are denominated in a currency other than U.S. dollars, the Funds will be subject to currency risk, which is the risk that an increase in the U.S. dollar relative to the foreign currency will reduce returns or portfolio value. Generally, when the U.S. dollar rises in value against a foreign currency, the Funds’ investments denominated in that currency will lose value because their currency is worth fewer U.S. dollars; the opposite effect occurs if the U.S. dollar falls in relative value. Investments and other assets and liabilities denominated in foreign currencies are converted into U.S. dollars on a spot (i.e. cash) basis at the spot rate prevailing in the foreign currency exchange market at the time of valuation. Purchases and sales of investments and income denominated in foreign currencies are translated into U.S. dollars on the respective dates of such transactions.The books and records of the Funds are maintained in

56

U.S. dollars. Assets, including investments, and liabilities denominated in foreign currencies are translated into U.S. dollars at the end of each day. Purchases and sales of securities, income and expenses are translated into U.S. dollars at the prevailing exchange rate on the respective dates of the transactions.

Net realized foreign currency gains and losses resulting from changes in exchange rates associated with (i) foreign currency, (ii) investments and (iii) derivatives include foreign currency gains and losses between trade date and settlement date of the transactions, foreign currency transactions, and the difference between the amounts of interest and dividends recorded on the books of the Funds and the amounts actually received are recognized as a component of “Net realized gain (loss) from foreign currency transactions” on the Statement of Operations, when applicable.

The unrealized gains and losses resulting from changes in foreign currency exchange rates and changes in foreign exchange rates associated with (i) investments and (ii) other assets and liabilities are recognized as a component of “Change in unrealized appreciation (depreciation) on foreign currency translations” on the Statement of Operations, when applicable. The unrealized gains and losses resulting from changes in foreign exchange rates associated with investments in derivatives are recognized as a component of the respective derivative’s related “Change in unrealized appreciation (depreciation)” on the Statement of Operations, when applicable.

Foreign Taxes: The Funds may be subject to foreign taxes on income, gains on investments or foreign currency repatriation, a portion of which may be recoverable. The Funds will accrue such taxes and recoveries as applicable, based upon the current interpretation of tax rules and regulations that exist in the markets in which the Funds invest.

Indemnifications: Under the Funds’ organizational documents, their officers and trustees are indemnified against certain liabilities arising out of the performance of their duties to the Funds. In addition, in the normal course of business, the Funds enter into contracts that provide general indemnifications to other parties. The Funds’ maximum exposure under these arrangements is unknown as this would involve future claims that may be made against the Funds that have not yet occurred. However, the Funds have not had prior claims or losses pursuant to these contracts and expects the risk of loss to be remote.

Investments and Investment Income: Securities transactions are accounted for as of the trade date for financial reporting purposes. Realized gains and losses on securities transactions are based upon the specific identification method. Dividend income is recorded on the ex-dividend date or, for certain foreign securities, when information is available. Non-cash dividends received in the form of stock, if any, are recognized on the ex-dividend date and recorded at fair value. Interest income is recorded on an accrual basis. Interest income also reflects payment-in-kind (“PIK”) interest and paydown gains and losses, if any. PIK interest represents income received in the form of securities in lieu of cash. Securities lending income is comprised of fees earned from borrowers and income earned on cash collateral investments.

Netting Agreements: In the ordinary course of business, the Funds may enter into transactions subject to enforceable International Swaps and Derivatives Association, Inc. (ISDA) master agreements or other similar arrangements (“netting agreements”). Generally, the right to offset in netting agreements allows each Fund to offset certain securities and derivatives with a specific counterparty, when applicable, as well as any collateral received or delivered to that counterparty based on the terms of the agreements. Generally, each Fund manages its cash collateral and securities collateral on a counterparty basis. With respect to certain counterparties, in accordance with the terms of the netting agreements, collateral posted to the Funds is held in a segregated account by the Funds’ custodian and/or with respect to those amounts which can be sold or repledged, are presented in the Funds’ Portfolio of Investments or Statement of Assets and Liabilities.

The Funds’ investments subject to netting agreements as of the end of the reporting period, if any, are further described later in these Notes to Financial Statements.

Segment Reporting: Each Fund represents a single operating segment. The officers of the Funds act as the chief operating decision maker (“CODM”). The CODM monitors the operating results of each Fund as a whole and is responsible for each Fund’s long-term strategic asset allocation in accordance with the terms of its prospectus, based on a defined investment strategy which is executed by the Fund’s portfolio managers as a team. The financial information in the form of the Fund’s portfolio composition, total returns, expense ratios and changes in net assets (i.e., changes in net assets resulting from operations, subscriptions and redemptions), which are used by the CODM to assess the segment’s performance versus the Fund’s comparative benchmarks and to make resource allocation decisions for the Fund’s single segment, is consistent with that presented within the Fund’s financial statements. Segment assets are reflected on the Statement of Assets and Liabilities as “total assets” and significant segment revenues and expenses are listed on the Statement of Operations.

New Accounting Pronouncement: In December 2023, the FASB issued ASU No. 2023-09, Income Taxes (Topic 740) Improvements to Income tax disclosures (“ASU 2023-09”). The primary purpose of the amendments within ASU 2023-09 is to enhance the transparency and decision usefulness of income tax disclosures primarily related to the rate reconciliation table and income taxes paid information. The amendments in ASU 2023-09 are effective for annual periods beginning after December 15, 2024. Management is currently evaluating the implications of these changes on the financial statements.

3. Investment Valuation and Fair Value Measurements

The Funds’ investments in securities are recorded at their estimated fair value utilizing valuation methods approved by the Adviser, subject to oversight of the Board. Fair value is defined as the price that would be received upon selling an investment or transferring a liability in an orderly transaction to an independent buyer in the principal or most advantageous market for the investment. U.S. GAAP establishes the three-tier hierarchy which is used to maximize the use of observable market data and minimize the use of unobservable inputs and to establish classification of fair value measurements for disclosure purposes. Observable inputs reflect the assumptions market participants would use in pricing the asset or liability.

57

Notes to Financial Statements (continued)

Observable inputs are based on market data obtained from sources independent of the reporting entity. Unobservable inputs reflect management’s assumptions about the assumptions market participants would use in pricing the asset or liability. Unobservable inputs are based on the best information available in the circumstances. The following is a summary of the three-tiered hierarchy of valuation input levels.

Level 1 – Inputs are unadjusted and prices are determined using quoted prices in active markets for identical securities.

Level 2 – Prices are determined using other significant observable inputs (including quoted prices for similar securities, interest rates, credit spreads, etc.).

Level 3 – Prices are determined using significant unobservable inputs (including management’s assumptions in determining the fair value of investments).

A description of the valuation techniques applied to the Funds’ major classifications of assets and liabilities measured at fair value follows:

Equity securities and exchange-traded funds listed or traded on a national market or exchange are valued based on their last reported sales price or official closing price of such market or exchange on the valuation date. Foreign equity securities and registered investment companies that trade on a foreign exchange are valued at the last reported sales price or official closing price on the principal exchange where traded, and converted to U.S. dollars at the prevailing rates of exchange on the valuation date. For events affecting the value of foreign securities between the time when the exchange on which they are traded closes and the time when the Funds’ net assets are calculated, such securities will be valued at fair value in accordance with procedures adopted by the Adviser, subject to the oversight of the Board. To the extent these securities are actively traded and no valuation adjustments are applied, they are generally classified as Level 1. When valuation adjustments are applied to the most recent last sales price or official closing price, these securities are generally classified as Level 2.

Prices of certain American Depositary Receipts (“ADR”) held by the Funds that trade in the United States are valued based on the last traded price, official closing price, or an evaluated price provided by the pricing services and are generally classified as Level 1 or 2.

Purchased and written options traded and listed on a national market or exchange are valued at the mean of the closing bid and asked prices and are generally classified as Level 1.

Over-the-counter (“OTC”) options are marked-to-market daily based upon a price supplied by a pricing service. OTC options are generally classified as Level 2.

Investments in investment companies are valued at their respective NAVs or share price on the valuation date and are generally classified as Level 1.

Repurchase agreements are valued at contract amount plus accrued interest, which approximates market value. These securities are generally classified as Level 2.

For any portfolio security or derivative for which market quotations are not readily available or for which the Adviser deems the valuations derived using the valuation procedures described above not to reflect fair value, the Adviser will determine a fair value in good faith using alternative procedures approved by the Adviser, subject to the oversight of the Board. As a general principle, the fair value of a security is the amount that the owner might reasonably expect to receive for it in a current sale. A variety of factors may be considered in determining the fair value of such securities, which may include consideration of the following: yields or prices of investments of comparable quality, type of issue, coupon, maturity and rating, market quotes or indications of value from security dealers, evaluations of anticipated cash flows or collateral, general market conditions and other information and analysis, including the obligor’s credit characteristics considered relevant. To the extent the inputs are observable and timely, the values would be classified as Level 2; otherwise they would be classified as Level 3.

The following table summarizes the market value of the Funds’ investments as of the end of the reporting period, based on the inputs used to value them:

4. Portfolio Securities

Repurchase Agreements: In connection with transactions in repurchase agreements, it is each Fund’s policy that its custodian take possession of the underlying collateral securities, the fair value of which exceeds the principal amount of the repurchase transaction, including accrued interest, at all times. If the counterparty defaults, and the fair value of the collateral declines, realization of the collateral may be delayed or limited.

The following table presents the repurchase agreements for the Funds that are subject to netting agreements as of the end of the reporting period, and the collateral delivered related to those repurchase agreements.

QQQX Fixed Income Clearing Corporation 24,148,161 (24,631,171)
JCE Fixed Income Clearing Corporation 4,959,767 (5,059,011)

Securities Lending: Each Fund may lend securities representing up to one-third of the value of its total assets to broker-dealers, banks, and other institutions in order to generate additional income. When loaning securities, a Fund retains the benefits of owning the securities, including the economic equivalent of dividends or interest generated by the security. The loans are continuous, can be recalled at any time, and have no set maturity. The Funds’ custodian, State Street Bank and Trust Company, serves as the securities lending agent (the “Agent”).

When a Fund loans its portfolio securities, it will receive, at the inception of each loan, cash collateral equal to an amount not less than 100% of the market value of the loaned securities. The actual percentage of the cash collateral will vary depending upon the asset type of the loaned securities. Collateral for the loaned securities is invested in a government money market vehicle maintained by the Agent, which is subject to the requirements of Rule 2a-7 under the 1940 Act. The value of the loaned securities and the liability to return the cash collateral received are recognized on the Statement of Assets and Liabilities. If the market value of the loaned securities increases, the borrower must furnish additional collateral to the Fund, which is also recognized on the Statement of Assets and Liabilities. The market value of securities loaned is determined at the close of business of the Funds and any additional required collateral is delivered to the Funds on the next business day. Securities out on loan are subject to termination at any time at the option of the borrower or the Fund. Upon termination, the borrower is required to return to the Fund securities identical to the securities loaned. During the term of the loan, the Fund bears the market risk with respect to the investment of collateral and the risk that the Agent may default on its contractual obligations to the Fund. The Agent bears the risk that the borrower may default on its obligation to return the loaned securities as the Agent is contractually obligated to indemnify the Fund if at the time of a default by a borrower some or all of the loan securities have not been returned.

Securities lending income recognized by a Fund consists of earnings on invested collateral and lending fees, net of any rebates to the borrower and compensation to the Agent. Such income is recognized on the Statement of Operations.

As of the end of the current fiscal period, the total value of the loaned securities and the total value of collateral received were as follows:

Fund Aggregate Value of Securities on Loan — Equity Securities Cash Collateral Received*
SPXX $374,300 $380,031
QQQX 119,734 120,227

*May include cash and investment of cash collateral.

Purchases and Sales: Long-term purchases and sales during the current fiscal period were as follows:

Fund Non-U.S. Government Purchases Non-U.S. Government Sales
BXMX $   71,436,052 $ 168,465,048
DIAX 70,368,355 105,753,849
SPXX 55,516,548 74,570,139
QQQX 246,610,258 363,910,479
JCE 132,951,354 139,177,693

The Funds may purchase securities on a when-issued or delayed-delivery basis. Securities purchased on a when-issued or delayed-delivery basis may have extended settlement periods; interest income is not accrued until settlement date. Any securities so purchased are subject to market fluctuation during this period. If a Fund has outstanding when-issued/delayed-delivery purchases commitments as of the end of the reporting period, such amounts are recognized on the Statement of Assets and Liabilities.

5. Derivative Investments

Each Fund is authorized to invest in certain derivative instruments. As defined by U.S. GAAP, a derivative is a financial instrument whose value is derived from an underlying security price, foreign exchange rate, interest rate, index of prices or rates, or other variables. Investments in derivatives as of the end of and/or during the current fiscal period, if any, are included within the Statement of Assets and Liabilities and the Statement of Operations, respectively.

60

Options Transactions: The Funds may purchase (buy) or write (sell) put and call options on specific securities (including groups or “baskets” of specific securities), interest rates, stock indices and/or bond indices (each a “financial instrument”). Options can be settled either directly with the counterparty (over the counter) or through a central clearing house (exchange traded). Call and put options give the holder the right, in return for a premium paid, to purchase or sell, respectively, a financial instrument at a specified exercise price at any time during the period of the option.

When a Fund purchases an option, an amount equal to the premium paid (the premium plus commission) is recognized as an asset on the Statement of Asset and Liabilities. When a Fund writes an option, an amount equal to the net premium received (the premium less commission) is recognized as a liability on the Statement of Assets and Liabilities and is subsequently adjusted to reflect the current value of the written option until the option is exercised or expires or the Fund enters into a closing purchase transaction. The changes in the value of options purchased and/or written during the fiscal period are recognized as in unrealized appreciation (depreciation) on the Statement of Operations. When an option expires, the premiums received or paid are recognized as realized gains or losses on the Statement of Operations. When an option is exercised or a closing purchase transaction is entered into, the difference between the premium and the amount received or paid in a closing transaction is recognized as a realized gain or loss on the Statement of Operations.

The market risk associated with purchasing options is limited to the premium paid. The Fund, as writer of an option, has no control over whether the underlying instrument may be sold (called) or purchased (put) and as a result bears the risk of an unfavorable change in the market value of the instrument underlying the written option. There is also the risk the Fund may not be able to enter into a closing transaction because of an illiquid market.

During the current fiscal period, BXMX wrote call options on equity indices as per its stated strategy, with the notional amount of these options averaging 99% of the Fund’s assets.

During the current fiscal period, DIAX, SPXX, QQQX and JCE, each wrote put and call options on equity indices as per its stated dynamic overwriting strategy with the notional amounts of these options ranging from approximately 35-75% of each Fund’s assets. DIAX, SPXX, QQQX, and JCE also purchased put and call options as part of their overwrite strategy.

The average notional amount of outstanding options purchased during the current fiscal period, was as follows:

Fund
DIAX $2,370,000
SPXX 1,196,667
QQQX 1,453,333
JCE 128,333
  • The average notional amount is calculated based on the absolute aggregate notional amount of contracts outstanding at the beginning of the current fiscal period and at the end of each fiscal quarter within the current fiscal period.

The average notional amount of outstanding options written during the current fiscal period, was as follows:

Fund
BXMX $1,638,566,667
DIAX 372,998,333
SPXX 204,520,000
QQQX 892,972,500
JCE 114,158,333
  • The average notional amount is calculated based on the absolute aggregate notional amount of contracts outstanding at the beginning of the current fiscal period and at the end of each fiscal quarter within the current fiscal period.

As of the end of the reporting period, the following Funds have invested in derivative contracts which are reflected in the Statement of Assets and Liabilities as follows:

Derivative Instrument Risk Exposure Asset Derivatives — Location Value Liability Derivatives — Location Value
BXMX Options Written Equity - $- Options written, at value $(36,222,125 )

Market and Counterparty Credit Risk: In the normal course of business each Fund may invest in financial instruments and enter into financial transactions where risk of potential loss exists due to changes in the market (market risk) or failure of the other party to the transaction to perform (counterparty credit risk). The potential loss could exceed the value of the financial assets recorded on the financial statements. Financial assets, which potentially expose each Fund to counterparty credit risk, consist principally of cash due from counterparties on forward, option and swap transactions, when applicable. The extent of each Fund’s exposure to counterparty credit risk in respect to these financial assets approximates their carrying value as recorded on the Statement of Assets and Liabilities.

Each Fund helps manage counterparty credit risk by entering into agreements only with counterparties the Adviser believes have the financial resources to honor their obligations and by having the Adviser monitor the financial stability of the counterparties. Additionally, counterparties may be required to pledge collateral daily (based on the daily valuation of the financial asset) on behalf of each Fund with a value approximately equal to the amount of any unrealized gain above a pre-determined threshold. Reciprocally, when each Fund has an unrealized loss, the Funds have instructed the custodian to pledge assets of the Funds as collateral with a value approximately equal to the amount of the unrealized loss above a pre-determined threshold. Collateral pledges are monitored and subsequently adjusted if and when the valuations fluctuate, either up or down, by at least the pre-determined threshold amount.

6. Fund Shares

Common Shares Equity Shelf Programs and Offering Costs: The following Funds have filed a registration statement with the Securities and Exchange Commission (“SEC”) authorizing each Fund to issue additional common shares through one or more equity shelf programs (“Shelf Offering”), which became effective with the SEC during the current fiscal period.

62

Under this Shelf Offering, the Funds, subject to market conditions, may raise additional equity capital by issuing additional common shares from time to time in varying amounts and by different offering methods at a net price at or above each Fund’s NAV per common share. In the event the Fund’s Shelf Offering registration statement is no longer current, the Fund may not issue additional common shares until a post-effective amendment to the registration statement has been filed with the SEC.

Maximum aggregate offering, common shares sold and offering proceeds, net of offering costs under the Fund’s Shelf Offering during the Fund’s current and prior fiscal periods were as follows:

Six Months Ended 6/30/25 Year Ended 12/31/24 Six Months Ended 6/30/25 Year Ended 12/31/24
Maximum aggregate offering 4,235,232* 4,993,317 Unlimited Unlimited

  • For the period March 25, 2025 through June 30, 2025. 4,993,317 prior to March 25, 2025.

Costs incurred by the Funds in connection with their initial shelf registrations are recorded as a prepaid expense and recognized as “Deferred offering costs” on the Statement of Assets and Liabilities. These costs are amortized pro rata as common shares are sold and are recognized as a component of “Proceeds from shelf offering, net of offering costs” on the Statement of Changes in Net Assets. Any deferred offering costs remaining after the effectiveness of the initial shelf registration will be expensed. Costs incurred by the Funds to keep the shelf registration current are expensed as incurred and recognized as a component of “Other expenses” on the Statement of Operations.

Common Share Transactions: Transactions in common shares for the Funds during the Funds’ current and prior fiscal period, where applicable, were as follows:

7. Income Tax Information

Each Fund is a separate taxpayer for federal income tax purposes. Each Fund intends to distribute substantially all of its net investment income and net capital gains to shareholders and otherwise comply with the requirements of Subchapter M of the Internal Revenue Code applicable to regulated investment companies. Therefore, no federal income tax provision is required.

Each Fund files income tax returns in U.S. federal and applicable state and local jurisdictions. A Fund’s federal income tax returns are generally subject to examination for a period of three fiscal years after being filed. State and local tax returns may be subject to examination for an additional period of time depending on the jurisdiction. Management has analyzed each Fund’s tax positions taken for all open tax years and has concluded that no provision for income tax is required in the Fund’s financial statements.

8. Management Fees and Other Transactions with Affiliates

Management Fees: Management fee compensates the Adviser for overall investment advisory and administrative services and general office facilities. Gateway and NAM are compensated for their services to the Funds from the management fees paid to the Adviser.

Each Fund’s management fee consists of two components – a fund-level fee, based only on the amount of assets within each individual Fund, and a complex-level fee, based on the aggregate amount of all eligible fund assets managed by the Adviser. This pricing structure enables Fund shareholders to benefit from growth in the assets within their respective Fund as well as from growth in the amount of complex-wide assets managed by the Adviser.

The annual fund-level fee, payable monthly, for each Fund is calculated according to the following schedules:

Average Daily Managed Assets* — For the first $500 million 0.7000 % 0.7000 % 0.6600 % 0.6900 % 0.7500 %
For the next $500 million 0.6750 0.6750 0.6350 0.6650 0.7250
For the next $500 million 0.6500 0.6500 0.6100 0.6400 0.7000
For the next $500 million 0.6250 0.6250 0.5850 0.6150 0.6750
For managed assets over $2 billion 0.6000 0.6000 0.5600 0.5900 0.6500

The annual complex-level fee, payable monthly, for each Fund is calculated according to the following schedule:

Complex-Level Asset Breakpoint Level*
For the first $124.3 billion 0.1600 %
For the next $75.7 billion 0.1350
For the next $200 billion 0.1325
For eligible assets over $400 billion 0.1300
  • The complex-level fee is calculated based upon the aggregate daily “eligible assets” of all Nuveen-branded closed-end funds and Nuveen branded open-end funds (“Nuveen Mutual Funds”). Except as described below, eligible assets include the assets of all Nuveen-branded closed-end funds and Nuveen Mutual Funds organized in the United States. Eligible assets do not include the net assets of: Nuveen fund-of-funds, Nuveen money market funds, Nuveen index funds, Nuveen Large Cap Responsible Equity Fund or Nuveen Life Large Cap Responsible Equity Fund. In addition, eligible assets include a fixed percentage of the aggregate net assets of the active equity and fixed income Nuveen Mutual Funds advised by the Adviser’s affiliate, Teachers Advisors, LLC (except those identified above). The fixed percentage will increase annually until May 1, 2033, at which time eligible assets will include all of the aggregate net assets of the active equity and fixed income Nuveen Mutual Funds advised by Teachers Advisors, LLC (except those identified above). Eligible assets include closed-end fund assets managed by the Adviser that are attributable to financial leverage. For these purposes, financial leverage includes the closed-end funds’ use of preferred stock and borrowings and certain investments

64

in the residual interest certificates (also called inverse floating rate securities) in tender option bond (TOB) trusts, including the portion of assets held by a TOB trust that has been effectively financed by the trust’s issuance of floating rate securities, subject to an agreement by the Adviser as to certain funds to limit the amount of such assets for determining eligible assets in certain circumstances.

As of the end of the reporting period, the annual complex-level fee for each Fund was as follows:

Fund
BXMX 0.1569%
DIAX 0.1569%
SPXX 0.1569%
QQQX 0.1569%
JCE 0.1569%

Other Transactions with Affiliates: Each Fund is permitted to purchase or sell securities from or to certain other funds or accounts managed by the Sub-Adviser or by an affiliate of the Adviser (each an, “Affiliated Entity”) under specified conditions outlined in procedures adopted by the Board (“cross-trade”). These procedures have been designed to ensure that any cross-trade of securities by the Fund from or to an Affiliated Entity by virtue of having a common investment adviser (or affiliated investment adviser), common officer and/or common trustee complies with Rule 17a-7 under the 1940 Act. These transactions are effected at the current market price (as provided by an independent pricing service) without incurring broker commissions.

During the current fiscal period, the Funds engaged in cross-trades pursuant to these procedures as follows:

Fund Purchases Sales Realized Gain (Loss)
BXMX $ – $ – $ –
DIAX 9,466,583
SPXX 2,138,135
QQQX 7,036,353 124,070 17,830
JCE 9,495,948 5,153,421 202,236

9. Inter-Fund Borrowing and Lending

Inter-Fund Borrowing and Lending: The SEC has granted an exemptive order permitting registered open-end and closed-end Nuveen funds to participate in an inter-fund lending facility whereby the Nuveen 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, including the Funds covered by this shareholder report, 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 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 day’s 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 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.

During the current reporting period, none of the Funds covered by this shareholder report have entered into any inter-fund loan activity.

The Approval Process

At meetings held on April 28 and 29, 2025 (the “ Meeting ”), the Boards of Directors or Trustees (as the case may be) of the group of funds advised by Nuveen Fund Advisors, LLC (“ NFAL ” or the “ Adviser ”), including the Funds (as defined below), and the group of funds advised by Teachers Advisors, LLC (“ TAL ” and all such funds, collectively, the “ Nuveen funds ” or the “ funds ”) approved the renewal of the investment management agreements (each, an “ Investment Management Agreement ”) with NFAL and TAL, respectively. TAL and NFAL are affiliates as NFAL is a subsidiary of Nuveen, LLC, the investment arm of Teachers Insurance and Annuity Association of America (“ TIAA ”), and TAL is an indirect wholly owned subsidiary of TIAA. The Boards of Trustees of the Funds also approved the renewal of the sub-advisory agreements (each, a “ Sub-Advisory Agreement ”) with: (i) in the case of Nuveen S&P 500 Buy-Write Income Fund (the “ Buy-Write Fund ” ), Gateway Investment Advisers, LLC ( “ Gateway ” ), and (ii) in the case of Nuveen Dow 30SM Dynamic Overwrite Fund (the “ Dow 30 Fund ” ), Nuveen S&P 500 Dynamic Overwrite Fund (the “ S&P 500 Fund ” ), Nuveen Nasdaq 100 Dynamic Overwrite Fund (the “ Nasdaq 100 Fund ” ) and Nuveen Core Equity Alpha Fund (the “ Core Equity Alpha Fund ” ), Nuveen Asset Management, LLC ( “ NAM ” and, each of NAM and Gateway, a “ Sub-Adviser ” ). NAM is also an affiliate of the Adviser.

The Boards of Directors or Trustees of the Nuveen funds are each a “Board” or collectively the “Board” (as the context may dictate) and the directors or trustees (as the case may be) are each a “Board Member.” The Board Members of each Board are not “interested persons” (as defined under the Investment Company Act of 1940 (the “1940 Act”)) and, therefore, each Board is deemed to be comprised of all disinterested Board Members. References to a Board and the Board Members are interchangeable.

In accordance with applicable law, following up to an initial two-year period, the Board of each Fund considers the renewal of each Investment Management Agreement and Sub-Advisory Agreement on behalf of the Fund on an annual basis. The Investment Management Agreements and Sub-Advisory Agreements are collectively referred to as the “Advisory Agreements,” and the Adviser and each Sub-Adviser are collectively the “Fund Advisers” and each a “Fund Adviser.” Below is a summary of the annual review process the Board undertook related to its most recent renewal of the Advisory Agreements with respect to each Nuveen fund covered by this report (each, a “Fund” and, collectively, the “Funds”).

To reach their determination, the Board Members considered the review of the Advisory Agreements to be an ongoing process. The Board Members employed the accumulated information, knowledge and experience they had gained during their tenure as disinterested Board Members on the respective Board of the Nuveen funds and its committees in overseeing the applicable funds and working with the respective investment advisers and sub-advisers in their review of the advisory agreements for the fund complex. The Board and/or its committees meet regularly throughout the year and at these meetings, the Board Members received materials and discussed information covering a wide range of topics pertinent to the annual consideration of the renewal of the Advisory Agreements. Such topics include, but are not limited to, the investment performance of the funds over various periods; investment oversight matters; economic, market and regulatory developments; any significant organizational or other developments impacting a Fund Adviser and its strategic plans for its business; product initiatives for various funds; fund expenses; compliance, regulatory and risk management matters; trading practices; the derivatives risk management program; management of distributions; valuation of securities; payments to financial intermediaries; securities lending (as applicable); and closed-end fund market activity, capital management initiatives, institutional ownership, management of leverage financing, the secondary market trading of the closed-end funds and any actions taken to address market discounts to net asset value. The Board also seeks to meet at its regular quarterly meetings with members of senior management to discuss various topics, including market conditions, industry developments and any significant developments or strategic plans for the Fund Advisers, if any.

To help with the review of performance, the Board and/or its committees periodically received and discussed presentations from member(s) of investment teams throughout the year, culminating in an annual performance review of the Nuveen funds at the Board’s meeting held on February 25-26, 2025 (the “February Meeting”). The presentations, discussions and meetings during the year provide a means for the Board Members to evaluate and consider the level, breadth and quality of services provided by the Fund Advisers and any changes to such services over time in light of new or modified regulatory requirements, changes to market conditions or other factors.

In addition to the materials and discussions that occurred at prior meetings, the Board, through its independent legal counsel, requested and received extensive materials and information prepared specifically for its review of the Advisory Agreements. During the year, management worked with an ad hoc committee established by the Board to help enhance and streamline the materials provided in connection with the annual review of the Advisory Agreements. The materials provided at the Meeting and/or prior meetings covered a wide range of matters including, but not limited to, a description of the nature, extent and quality of services provided by the Fund Advisers; a review of each Sub-Adviser and applicable investment team; an analysis of fund performance with a focus on funds considered to have met certain challenged performance measurements; an analysis of the fees and expense ratios of the Nuveen funds with a focus on funds considered to have certain expense characteristics; a list of management fee and sub-advisory fee schedules; an analysis of advisory fees compared to fees assessed to other types of clients; a description of portfolio manager

compensation; certain profitability and/or financial data; and a description of indirect benefits received by the Fund Advisers as a result of their relationships with the Nuveen funds. The Board also considered information provided by Broadridge Financial Solutions, Inc. (“Broadridge”), an independent provider of investment company data, comparing fee and expense levels of each respective Fund to those of a peer universe.

With respect to Gateway, which is not affiliated with NFAL, the Board of the Buy-Write Fund, through independent legal counsel, requested and received materials and information prepared specifically for its review of the Sub-Advisory Agreement applicable to Gateway. The materials included, among other things, a description of the services provided, a summary of the experience of key personnel and its organizational structure, its fee schedule and a comparison to certain fee data of other clients, an evaluation of the performance of the Buy-Write Fund, certain profitability data of Gateway and indirect benefits to Gateway.

The information prepared specifically for the annual review supplemented the information provided to the Board and its committees and the evaluations of the Nuveen funds by the Board and its committees during the year. The Board’s review of the Advisory Agreements is based on all the information provided to the Board and its committees over time. The performance, fee and expense data and other information provided by a Fund Adviser, Broadridge or other service providers were not independently verified by the Board Members.

As part of their review, the Board Members and independent legal counsel met in executive session on April 9, 2025 to review and discuss materials provided in connection with their annual review of the Advisory Agreements. After reviewing this information, the Board Members requested, directly or through independent legal counsel, additional information, and the Board subsequently reviewed and discussed the responses to these follow-up questions and requests. The Board Members and independent legal counsel met again in executive session on April 17, 2025 (together with the April 9, 2025 executive session, the “Executive Sessions”) to discuss the responses to the initial supplemental information request and, following their review of the data provided, requested management present certain additional information at the Meeting. In addition to the Executive Sessions, the Board Members met in additional executive sessions prior to and during the Meeting. During the Meeting, the Board Members considered the responses, invited representatives of management to provide additional information and determined that the information provided (whether oral or written) was responsive to their requests.

The Board Members were advised by independent legal counsel during the annual review process as well as throughout the year, including meeting in executive sessions with such counsel at which no representatives of management were present. In connection with their annual review, the Board Members also received a memorandum from independent legal counsel outlining their fiduciary duties and legal standards in reviewing the Advisory Agreements, including guidance from court cases evaluating advisory fees.

After the discussions and with the background and knowledge described above, the Board Members approved the continuation of the Advisory Agreements on behalf of the applicable Funds for an additional one-year period. The Board did not identify any single factor as all-important or controlling, but rather each decision reflected the comprehensive consideration of all the information (written or oral) provided to the Board and its committees throughout the year as well as the materials prepared specifically in connection with the annual review process. The contractual arrangements may reflect the results of prior year(s) of review, negotiation and information provided in connection with the Board’s annual review of the Funds’ advisory arrangements and oversight of the Funds. Each Board Member may have attributed different levels of importance to the various factors and information considered in connection with the annual review process and may have placed different emphasis on the relevant information year to year in light of, among other things, changing market and economic conditions. A summary of the principal factors and information, but not all the factors, the Board considered in deciding to renew the Advisory Agreements is set forth below.

A. Nature, Extent and Quality of Services

In evaluating the renewal of the Advisory Agreements, the Board Members received and considered information regarding the nature, extent and quality of the applicable Fund Adviser’s services provided to each respective Fund. With this approach, they considered the roles of the Adviser and the respective Sub-Adviser in providing services to the Funds.

The Board considered that the Adviser provides a wide array of management, oversight and other services to manage and operate the Funds. The Board considered the Adviser and its affiliates’ dedication of resources, time, people and capital as well as consistent program of improvement and innovation aimed at keeping the Nuveen fund complex relevant and attractive for existing and new investors and meeting the needs of an increasingly complex regulatory environment. Among the information provided in connection with the review of services at the Meeting and/or prior meetings, the Board considered a description of the organizational changes at the Adviser during the year, the management teams that comprise the various support and investment functions for the funds and the background of certain personnel who support the funds. The Board considered the significant resources, both financial and personnel, the Adviser and its affiliates had committed over the past several years in working to bring the asset management businesses of Nuveen and TIAA under one centralized umbrella and to consolidate their respective fund families to the benefit of the funds through, among other things, enhanced operating efficiencies, centralized investment leadership and a centralized shared resources and support model. To help ensure the continuation of services, the Board considered, among other things, management’s emphasis on succession planning and key person risk evaluation pursuant to which certain management team(s) meet annually to conduct a comprehensive review of successors to key positions, to develop and monitor corporate-wide standards and procedures in seeking to help ensure the firm may continue to operate in the event of business disruptions, and to review staffing and compensation levels to help remain competitive with peers in the industry. The Board considered a description of the application of business continuity plans and the periodic testing and review of such plans. As noted below, the Board also considered certain financial data of the Adviser and TIAA in assessing the financial stability and condition of the Adviser to provide a high level of quality of services to the Funds.

In its review, the Board considered that the Funds operated in a highly regulated industry and the scope and complexity of the services and resources that the Adviser and its affiliates must provide to manage and operate the Funds have expanded over the years due to regulatory, market and other developments. Such services included maintaining and monitoring the Nuveen funds’ compliance programs, risk management programs,

70

liquidity risk management programs, derivatives risk management programs and cybersecurity programs. The Board and/or its Compliance, Risk Management and Regulatory Oversight Committee received reports regarding the funds’ compliance policies and procedures and matters undertaken thereunder as well as other compliance initiatives on a regular basis.

In considering the breadth and quality of services the Adviser and its various teams provide, the Board considered that the Adviser provides investment advisory services. With respect to the Funds, such Funds utilize the applicable Sub-Adviser to manage the portfolios of the Funds subject to the supervision of the Adviser. Accordingly, the Board considered that the Adviser and its affiliates, among other things, oversee and review the performance of the respective Sub-Adviser and its investment team(s); evaluate Fund performance and market conditions; evaluate investment strategies and recommend changes thereto; oversee trade execution and, as applicable, securities lending; evaluate investment risks; and manage valuation matters. As noted below, the Board also considered the Nuveen funds’ performance over various time periods throughout the year.

In addition to the portfolio management services provided to the Funds (including indirectly by overseeing a Sub-Adviser), the Board considered the extensive compliance, regulatory, administrative and other services the Adviser and its various teams or affiliates provide to manage and operate the applicable funds, including but not limited to: distribution management services pursuant to which management seeks to implement distribution policies and set distribution levels consistent with each fund’s product design and positioning; compliance services including establishing and maintaining broad-based compliance policies across the Nuveen fund complex, evaluating the compliance programs of various fund services providers, conducting ongoing risk assessments and testing, monitoring portfolio compliance with investment and regulatory requirements and providing a comprehensive compliance training program; providing regulatory advocacy services, including submitting comments on regulatory proposals and monitoring regulatory developments that may impact the fund(s); providing support to the Board and its committees throughout the year, including providing reports on a wide range of topics relating to the operations and management of the funds, helping to refine the materials provided to the Board and/or its committees and providing educational sessions on various topics; establishing and reviewing the services provided by other fund service providers (such as a fund’s custodian, accountant, and transfer agent); providing legal support services; and evaluating trade allocation and execution.

Such services also include managing leverage; providing capital management and secondary market services (such as implementing common share shelf offerings, capital return programs and common share repurchases); and maintaining a closed-end fund investor relations program. The Board considered that management actively monitors any discount from net asset value per share at which a fund’s common stock trades and evaluates potential avenues to mitigate the discount, including evaluating the level of distributions that the fund pays.

Aside from the services provided, the Board considered the financial resources of the Adviser and/or its affiliates and their willingness to make investments to support the funds. The Board considered the funds’ access to a seed capital budget provided by the Adviser and/or its affiliates to support new or existing funds and/or facilitate changes for a respective fund. The Board considered the benefits to shareholders of investing in a Fund that is a part of a large fund complex with a variety of investment disciplines, capabilities, and expertise. The Board considered the overall reputation and capabilities of the Adviser and its affiliates and the Adviser’s continuing commitment to provide high quality services.

In its review, the Board also considered the significant risks borne by the Adviser and its affiliates in connection with their services to the Nuveen funds, including entrepreneurial risks in sponsoring and supporting new funds and smaller funds and ongoing risks with managing the Funds, such as investment, operational, reputational, regulatory, compliance and litigation risks.

The Board considered the division of responsibilities between the Adviser and the respective Sub-Adviser and considered that each Sub-Adviser and its investment personnel, as noted, generally are responsible for the management of the respective Fund’s portfolio under the oversight of the Adviser and the Board. The Board considered an analysis of each Sub-Adviser provided by the Adviser which included, among other things, a summary of changes (if any) in the leadership teams and/or portfolio manager teams; the performance of the funds sub-advised by the respective Sub-Adviser over various periods of time that met certain performance screening measurements; and data reflecting product changes (if any) taken with respect to certain funds. The Board considered that the Adviser recommended the renewal of the Sub-Advisory Agreements.

Based on its review, the Board determined, in the exercise of its reasonable business judgment, that it was satisfied with the nature, extent and quality of services provided to the respective Funds under each applicable Advisory Agreement.

B. The Investment Performance of the Funds and Fund Advisers

In evaluating the quality of the services provided by the Fund Advisers, the Board also considered a variety of investment performance data of the Funds. In leading up to the annual review, the Board and/or its Investment Committee considered, among other things, Fund performance (based on net asset value net of fees) over the quarter, one-, three- and five-year periods ending December 31, 2024 on an absolute basis and as compared to the performance of comparable peers (the “ Performance Peer Grou p ”) and to a benchmark for the prescribed periods. Prior to the Meeting, the Board also received updated Fund performance over the quarter, one-, three- and five-year periods ended March 31, 2025 on an absolute basis and in comparison to the Performance Peer Group and a benchmark for the prescribed periods. In its review of relative performance, the Board considered a Fund’s performance relative to its Performance Peer Group, among other things, by evaluating its quartile ranking with the 1 St quartile representing the top performing funds within the Performance Peer Group and the 4 th quartile representing the lowest performing funds.

The Board took into account the performance data, presentations and discussions (written and oral) that were provided at the Meeting and in prior meetings over time in evaluating fund performance, including particular focus on management’s analysis of the performance of funds that met certain screening measurements as determined pursuant to a methodology approved by the Board or additional measurements as determined by management’s investment analysts. As various Nuveen funds have modified their portfolio teams and/or made significant changes to their portfolio strategies over time, the Board reviewed, among other things, certain tracking performance data over specific periods comparing performance before and after such changes. The Board also considered each Fund’s performance relative to its blended benchmark as well as the performance attributed to the equity portion and the options portion of the Fund’s portfolio relative to their respective benchmark for the trailing one-year period ended December 31, 2024.

71

Statement Regarding Basis for Approval of Investment Advisory Contract

(continued)

In evaluating performance, the Board considered some of the limitations of the performance data. The Board considered, among other things, that performance data reflects performance over a specified period which may differ significantly depending on the ending dates selected, particularly during periods of market volatility. Further, the Board considered that regardless of the performance period reviewed by the Board, shareholders may evaluate performance based on their own respective holding periods which may differ from the performance periods reviewed by the Board and lead to differing results. With respect to comparative performance, the Board considered that differing investment objectives, investment strategies, dates of inception, type and cost of leverage (if any), asset size and other factors between the Performance Peer Group and the respective Fund necessarily lead to differences in performance results. Similarly, differences in the investment objective(s) and strategies of a Fund and its benchmark (particularly an actively managed fund that does not directly follow an index) as well as the costs of operating a Fund would contribute to differences in performance results. To assist the Board in its review of the comparability of the relative performance, management generally has ranked the relevancy of the Performance Peer Groups to the applicable funds (subject to certain exceptions) as low, medium or high.

The Board also considered that secondary market trading of shares of the closed-end funds also continues to be a priority for the Board given its importance to shareholders, and therefore, the Board and/or its Closed-End Fund Committee reviews certain performance data reflecting, among other things, the premiums and discounts at which the shares of the closed-end funds have traded as of specified dates at their quarterly meetings with an annual review of the closed-end fund market for the 2024 calendar year at its February Meeting. In its review, the Board considered, among other things, market conditions for closed-end funds, changes to investment mandates and guidelines, distribution policies, and leverage management; additional share offerings, share repurchases (if any) and similar capital market actions; and effective communications programs to build greater awareness and deepen understanding of closed-end funds. As applicable, the Board considered, among other things, the impact of leverage on a closed-end fund’s common share earnings and total return.

The Board evaluated performance in light of various relevant factors which may include, among other things, general market conditions, issuer- specific information, asset class information, leverage and fund cash flows. The Board considered that long-term performance could be impacted by even one period of significant outperformance or underperformance and that a single investment theme could disproportionately affect performance. Further, the Board considered that market and economic conditions may significantly impact a Fund’s performance, particularly over shorter periods, and such performance may be more reflective of such economic or market events and not necessarily reflective of management skill. Although the Board reviews short-, intermediate- and longer-term performance data, the Board considered that longer periods of performance may reflect full market cycles.

In their review from year to year, the Board Members consider and may place different emphasis on the relevant information in light of changing circumstances in market and economic conditions. In evaluating performance, the Board focused particular attention on funds with less favorable performance records. However, depending on the facts and circumstances, including any differences between the respective fund and its benchmark and/or Performance Peer Group, the Board may be satisfied with a fund’s performance notwithstanding that its performance may be below that of its benchmark and/or peer group for certain periods. With respect to any funds for which the Board has identified performance issues, the Board seeks to monitor such funds more closely until performance improves, discuss with the Adviser the reasons for such results, consider whether any steps are necessary or appropriate to address such issues, discuss and evaluate the potential consequences of such steps and review the results of any steps undertaken.

The performance determinations with respect to each Fund are summarized below:

• For the Buy-Write Fund, the Board considered that although the Fund’s performance was below the performance of its benchmark for the one-year period ended December 31, 2024, the Fund outperformed its benchmark for the three- and five-year periods ended December 31, 2024. In addition, the Fund ranked in the second quartile of its Performance Peer Group for the one-, three- and five-year periods ended December 31, 2024. On the basis of the Board’s ongoing review of investment performance and all relevant factors, including the relative market conditions during certain reporting periods, the Fund’s investment objective(s) and management’s discussion of performance, the Board concluded that the Fund’s performance supported renewal of the Advisory Agreements.

• For the Dow 30 Fund, the Board considered that although the Fund’s performance was below the performance of its benchmark for the one-, three- and five-year periods ended December 31, 2024 and the Fund ranked in the fourth quartile of its Performance Peer Group for the five-year period ended December 31, 2024, the Fund ranked in the third quartile of its Performance Peer Group for the one- and three-year periods ended December 31, 2024. In considering performance, the Board, however, considered that the Performance Peer Group was classified as low for relevancy. On the basis of the Board’s ongoing review of investment performance and all relevant factors, including the relative market conditions during certain reporting periods, the Fund’s investment objective(s) and management’s discussion of performance, the Board concluded that the Fund’s performance supported renewal of the Advisory Agreements.

• For the S&P 500 Fund, the Board considered that although the Fund’s performance was below the performance of its benchmark for the one-, three- and five-year periods ended December 31, 2024, the Fund ranked in the second quartile of its Performance Peer Group for such periods. On the basis of the Board’s ongoing review of investment performance and all relevant factors, including the relative market conditions during certain reporting periods, the Fund’s investment objective(s) and management’s discussion of performance, the Board concluded that the Fund’s performance supported renewal of the Advisory Agreements.

• For the Nasdaq 100 Fund, the Board considered that although the Fund’s performance was below the performance of its benchmark for the three- and five-year periods ended December 31, 2024, the Fund outperformed its benchmark for the one-year period ended December 31, 2024. In addition, the Fund ranked in the first quartile of its Performance Peer Group for the one-, three- and five-year periods ended December 31, 2024. In considering performance, the Board, however, considered that the Performance Peer Group was classified as low for relevancy. On the basis of the Board’s ongoing review of investment performance and all relevant factors, including the relative market conditions during certain reporting periods, the Fund’s investment objective(s) and management’s discussion of performance, the Board concluded that the Fund’s performance supported renewal of the Advisory Agreements.

72

• For the Core Equity Alpha Fund, the Board considered that the Fund outperformed its benchmark and ranked in the first quartile of its Performance Peer Group for the one-, three- and five-year periods ended December 31, 2024. On the basis of the Board’s ongoing review of investment performance and all relevant factors, including the relative market conditions during certain reporting periods, the Fund’s investment objective(s) and management’s discussion of performance, the Board concluded that the Fund’s performance supported renewal of the Advisory Agreements.

C. Fees, Expenses and Profitability

  1. Fees and Expenses

As part of the annual review, the Board Members considered, among other things, the management fee schedules for the respective Fund. In addition to the management fee arrangements, the Board Members considered a Fund’s operating expense ratio as it more directly reflected a shareholder’s total costs in investing in the respective Fund.

In its review, the Board considered that the management fees of the Funds were generally comprised of two components, a fund-level component and a complex-level component, each with its own breakpoint schedule, subject to certain exceptions. The Board considered that in 2024, the Board approved a revised complex-wide breakpoint schedule which simplified and reduced the complex-level fee rates at various thresholds and expanded the eligible funds whose assets would be included in calculating the complex-level fee, effective May 1, 2024. The Board considered that the complex-level component is intended to be an efficient mechanism designed to help share cost efficiencies with shareholders as the complex- wide assets grow.

The Board also considered comparative fee and expense information prepared by an independent third-party provider of fund data. More specifically, the Board Members generally reviewed, among other things, each Fund’s management fee rates and net total expense ratio in relation to similar data for a comparable universe of peers (the “Expense Universe”). In their review, the Board Members considered, in particular, each fund with a net total expense ratio (based on common assets and excluding investment-related costs such as the costs of leverage and taxes) meeting certain expense screening criteria adopted by the Board when compared to its Expense Universe and management’s commentary as to the factors contributing to each such fund’s relative net total expense ratio. The Board also considered, in relevant part, a fund’s management fee in light of its performance history with particular focus on any fund identified as having a higher management fee and/or expense ratio compared to peers coupled with experiencing a period of challenged performance.

In their review, the Board Members considered the methodology Broadridge employed to establish its Expense Universe. The Board further considered that differences between the applicable Fund and its Expense Universe, as well as changes to the composition of the Expense Universe from year to year, may limit some of the value of the comparative data. The Board Members also considered that it can be difficult to compare management fees among funds with peers as there are variations in the services that are included for the fees paid. The Board Members took these limitations and differences into account when reviewing comparative peer data.

In addition, although the Board reviewed net total expense ratio both including and excluding investment-related expenses (e.g., leverage costs), as applicable, the Board considered that leverage expenses will vary across funds and peers because of differences in the forms and terms of leverage employed by the respective fund and therefore generally considered each closed-end fund’s net total expense ratio and fees excluding investment- related costs and taxes. The Board also considered that the use of leverage may create a conflict of interest for the respective Adviser and Sub- Adviser given the increase of assets from leverage upon which an advisory or sub-advisory fee is based but also considered the impact of leverage on the fund’s return. The Board Members considered, however, that the Adviser and respective Sub-Adviser would seek to manage the potential conflict by recommending to the Board to leverage the applicable fund or increase such leverage when the respective Fund Adviser has determined that such action would be in the best interests of the respective fund and its common shareholders and by periodically reviewing with the Board the fund’s performance and the impact of the use of leverage on that performance.

With respect to the Sub-Advisers, the Board also considered, among other things, the sub-advisory fee schedule paid to the respective Sub-Adviser in light of the sub-advisory services provided to the respective Fund. In its review, the Board considered that the compensation paid to a Sub- Adviser is the responsibility of the Adviser, not the Funds.

The Board’s considerations regarding the comparative fee data for each Fund are set forth below:

• For the Buy-Write Fund, the Fund’s contractual management fee rate, actual management fee rate and net total expense ratio were each below the Expense Universe median.

• For the Dow 30 Fund, the Fund’s contractual management fee rate, actual management fee rate and net total expense ratio were each below the Expense Universe median.

• For the S&P 500 Fund, the Fund’s contractual management fee rate, actual management fee rate and net total expense ratio were each below the Expense Universe median.

• For the Nasdaq 100 Fund, the Fund’s contractual management fee rate, actual management fee rate and net total expense ratio were each below the Expense Universe median.

• For the Core Equity Alpha Fund, the Fund’s contractual management fee rate, actual management fee rate and net total expense ratio were each below the Expense Universe median.

73

Statement Regarding Basis for Approval of Investment Advisory Contract

(continued)

Based on its review of the information provided, the Board determined that each Fund’s management fees (as applicable) to a Fund Adviser were reasonable in light of the nature, extent and quality of services provided to the Fund.

  1. Comparisons with the Fees of Other Clients

In evaluating the appropriateness of fees, the Board also considered that the Adviser, NAM and/or their affiliate(s) provide investment management services to other types of clients which may include, among others: separately managed accounts (“SMAs”), retail managed accounts, foreign funds (UCITS), other investment companies (as sub-advisers), limited partnerships and collective investment trusts. The Board considered certain fee data for these other types of clients managed in a similar manner to certain of the funds compared to the management fee of the applicable fund. The Board considered a description of various factors which contribute to the differences in the management fee rates of the funds compared to those charged to these other types of clients which limited the comparability of the data. In this regard, the Board considered that the differences in, among other things, the breadth of services provided by the Adviser and its affiliates to the funds compared to those provided to other clients; the expenses the Adviser and its affiliates incur in launching, operating and supporting a fund; the support services provided to shareholders; the extensive regulatory, disclosure and governance requirements applicable to funds; the establishment and maintenance of servicing relationships with various service providers for the funds; the manner of managing such assets; investment policies; investor profiles; and account sizes all may contribute to the variations in relative fee rates. Differences in the level of advisory services required for passively managed funds also contribute to differences in the management fee levels of such funds compared to actively managed funds. In addition, differences in the client base; governing bodies, regulatory and legal requirements; distribution; jurisdiction and operational complexities also would contribute to variations in management fees assessed the funds compared to foreign fund clients. Further, differences in the level of advisory and non-advisory services required and risk incurred when serving as a sub-adviser to other investment companies compared to serving as the Adviser to a Nuveen fund contribute to differences in the fees assessed. In this regard, the Board further considered the significant entrepreneurial, legal and regulatory risks that the Adviser incurs in sponsoring and managing the Funds. As a general matter, higher fee levels reflect higher levels of service provided by the Adviser, increased investment management complexity, greater product management requirements, and higher levels of business risk or some combination of these factors. The Board further considered that a Sub-Adviser’s fee is essentially for portfolio management services and therefore more comparable to the fees received for retail wrap accounts and other external sub-advisory mandates. The Board concluded that the varying levels of fees were reasonable given the foregoing.

With respect to Gateway, the Board Members reviewed certain fee data that the Sub-Adviser charges for other clients with comparable strategies to the Buy-Write Fund. The Board Members considered that the Sub-Advisory Agreement with Gateway, including the fees thereunder, was the result of arm’s length negotiations and Gateway’s fees were reasonable in relation to the fees it assessed other clients.

  1. Profitability of the Fund Advisers

In considering the costs of services to be provided and profits to be realized by the Adviser (which encompassed NAM) from its relationship with the Funds, the Board Members considered a variety of estimated profitability data from various perspectives including, among other things, (a) historical pre-distribution and post-distribution margins over specified periods for the Adviser’s services to the applicable funds; (b) certain profitability data on behalf of the Adviser attributable to servicing all applicable funds for 2024 and 2023; (c) certain profitability data of both the Adviser and TAL (as an adviser of certain other Nuveen funds) on a combined basis derived from types of funds in the aggregate (i.e., from closed-end funds, exchange- traded funds, interval funds and open-end funds) for 2024 and 2023; and (d) certain profitability data of both the Adviser and TAL on a combined basis by asset grouping of Nuveen funds in the aggregate (i.e., from equity, fund of funds, index, municipal bond and taxable fixed income funds). In addition, the Board considered profitability data at the per fund level for the respective adviser.

In reviewing the profitability data, the Board Members considered the subjective nature of calculating profitability as the information is not audited and is necessarily dependent on cost allocation methodologies to allocate expenses throughout the complex and among the various advisory products. The Board reviewed, among other things, a description of the cost allocation methodology employed to develop the profitability data. However, the Board Members considered that given there is no single universally recognized expense allocation methodology, other reasonable and valid allocation methodologies could be employed and could lead to significantly different profit and loss results and therefore developing profitability data is difficult, particularly on a per fund level.

Further, in considering the comparative margin data with peers, the Board Members considered the limitations of the comparative data given that peer data is not generally public and the calculation of profitability is subjective and affected by numerous factors (such as types of funds a peer manages, its business mix, its cost of capital, the numerous assumptions underlying the methodology used to allocate expenses and other factors) that can have a significant impact on the results. Given that the peer profitability data may reflect the different business mix of the respective peer firm, the Board also considered the pre- and post-distribution margins of Nuveen, LLC for each of the calendar years from 2020 through 2024.

Aside from the foregoing profitability data, the Board also considered, among other things, the audited statutory-basis financial statements of TIAA as of December 31, 2024 and 2023 and the related statutory-basis statements of operations, of changes in capital and contingency reserves and of cash flows for the years ended December 31, 2024, December 31, 2023 and December 31, 2022. The Board considered the benefit of an investment adviser and its parent with significant resources, particularly during periods of market volatility. The Board also considered the investments the Adviser, its parent and/or other affiliates made into their business.

With respect to Gateway, the Board Members considered a profitability and/or margin analysis for the Sub-Adviser, generally including revenues, expenses and operating margins for its advisory services to the Buy-Write Fund for the 2024 and 2023 calendar years. The Board considered that the sub-advisory fee would have been established through arm’s length negotiations between the Adviser and Gateway, and the Adviser pays Gateway out of its own revenues.

74

In evaluating the reasonableness of the compensation, the Board Members also considered the indirect benefits the Adviser or Sub-Advisers received that were directly attributable to the management of the applicable funds as discussed in further detail below. Based on its review, the Board was satisfied that the Adviser’s (together with NAM) and Gateway’s level of profitability from their relationship with the applicable Fund was not unreasonable in light of the nature, extent and quality of services provided.

D. Economies of Scale and Whether Fee Levels Reflect These Economies of Scale

The Board considered whether there have been economies of scale with respect to the management of the funds, whether these economies of scale have been appropriately shared with the funds and whether there is potential for realization of further economies of scale. Although the Board considered that economies of scale are difficult to measure with any precision and the rates at which certain expenses are incurred may not decline with a rise in assets, the Board considered that there are a variety of methods that may be employed to help share the benefits of economies of scale, including, among other things, through the use of breakpoints in the management fee schedule, the pricing of funds at scale at inception and investments in the Adviser’s business which can enhance the services provided to the funds for the fees paid. The Board considered such factors applicable to the particular Fund’s advisory fee structure.

As noted above, the Board considered that the management fee of the Adviser for the Funds generally was comprised of a fund-level component and a complex-level component each with its own breakpoint schedule. The Board also approved a revised complex-wide breakpoint schedule in 2024 which reduced the complex-level fee rates at various thresholds and expanded the assets included when calculating the complex-level fee. With this structure, the Board considered that the complex-level breakpoint schedule was designed to deliver the benefits of economies of scale to shareholders when the assets of the eligible participating funds in the complex pass certain thresholds even if the assets of a particular fund are unchanged or have declined, and the fund-level breakpoint schedules were designed to share economies of scale with shareholders if the particular fund grows. The Board reviewed the fund-level and complex-level fee schedules.

Although closed-end funds may make additional share offerings from time to time, the Board considered that closed-end funds have a more limited ability to increase their assets to attain additional economies of scale because the growth of their assets will occur primarily from the appreciation of their investment portfolios.

The Board Members also considered the continued reinvestment in Nuveen’s business to enhance its capabilities and services to the benefit of its various clients. The Board considered that many of these investments were not specific to individual Nuveen funds, but rather initiatives from which the family of funds as a whole may benefit. The Board further considered that the scope of the services of the Adviser and its affiliates have expanded over time without raising advisory fees to the funds, and this was also a means of sharing economies of scale with the funds and their shareholders. The Board considered the Adviser’s and/or its affiliates’ ongoing efforts to streamline the product line-up, among other things, to create more scaled funds which may help improve both expense and trading economies for participating funds.

Based on its review, the Board was satisfied that the current fee arrangements together with the reinvestment in management’s business appropriately shared any economies of scale with shareholders.

E. Indirect Benefits

The Board Members received and considered information regarding various indirect benefits the respective Fund Adviser or its affiliates may receive as a result of their relationship with the funds. These benefits included, among other things, economies of scale to the extent the Adviser or its affiliates share investment resources and/or personnel with other clients of the Adviser. Certain funds may also be used as investment options for other products or businesses offered by the Adviser and/or its affiliates, such as variable products, fund of funds and 529 education savings plans, and the Adviser and/or affiliates of the Adviser may serve as sub-adviser to various funds in which case all advisory and sub-advisory fees generated by such funds stay within Nuveen.

Further, the funds may pay the Adviser and/or its affiliates for other services, such as distribution. In this regard, the Board considered that an affiliate of the Adviser received compensation in 2024 for serving as an underwriter on shelf offerings of existing closed-end funds and reviewed the amounts paid for such services in 2024 and 2023.

In addition, the Board Members considered that the Adviser and NAM may utilize soft dollar brokerage arrangements attributable to the respective fund(s) to obtain research and other services for any or all of their clients, although the Board Members also considered (a) with respect to the Nuveen funds advised by the Adviser and sub-advised by NAM, reimbursements of such costs by the Adviser and/or NAM, and (b) with respect to the Buy-Write Fund, that Gateway does not generally generate soft dollar credits on behalf of transactions of such Fund.

The Adviser and its affiliates may also benefit from the advisory relationships with the Nuveen funds to the extent this relationship results in potential investors viewing the TIAA group of companies as a leading retirement plan provider in the academic and nonprofit market and a single source

for all their financial service needs. The Adviser and/or its affiliates may further benefit to the extent that they have pricing or other information regarding vendors the funds utilize in establishing arrangements with such vendors for other products.

Based on its review, the Board concluded that any indirect benefits received by a Fund Adviser as a result of its relationship with the Funds were reasonable in light of the services provided.

F. Other Considerations

The Board Members did not identify any single factor discussed previously as all-important or controlling. The Board Members concluded that the terms of each Advisory Agreement were reasonable, that the respective Fund Adviser’s fees were reasonable in light of the services provided to each Fund and that the Advisory Agreements be renewed for an additional one-year period.

Potential Material Conflicts of Interest

Actual or apparent conflicts of interest may arise when a portfolio manager has day-to-day management responsibilities with respect to more than one account. More specifically, portfolio managers who manage multiple accounts are presented a number of potential conflicts, including, among others, those discussed below.

The management of multiple accounts may result in a portfolio manager devoting unequal time and attention to the management of each account. Nuveen Asset Management seeks to manage such competing interests for the time and attention of portfolio managers by having portfolio managers focus on a particular investment discipline. Most accounts managed by a portfolio manager in a particular investment strategy are managed using the same investment models.

If a portfolio manager identifies a limited investment opportunity which may be suitable for more than one account, an account may not be able to take full advantage of that opportunity due to an allocation of filled purchase or sale orders across all eligible accounts. To deal with these situations, Nuveen Asset Management has adopted procedures for allocating limited opportunities across multiple accounts.

With respect to many of its clients’ accounts, Nuveen Asset Management determines which broker to use to execute transaction orders, consistent with its duty to seek best execution of the transaction. However, with respect to certain other accounts, Nuveen Asset Management may be limited by the client with respect to the selection of brokers or may be instructed to direct trades through a particular broker. In these cases, Nuveen Asset Management may place separate, non-simultaneous, transactions for a Fund and other accounts which may temporarily affect the market price of the security or the execution of the transaction, or both, to the detriment of the Fund or the other accounts.

Some clients are subject to different regulations. As a consequence of this difference in regulatory requirements, some clients may not be permitted to engage in all the investment techniques or transactions or to engage in these transactions to the same extent as the other accounts managed by a portfolio manager. Finally, the appearance of a conflict of interest may arise where Nuveen Asset Management has an incentive, such as a performance-based management fee, which relates to the management of some accounts, with respect to which a portfolio manager has day-to-day management responsibilities.

Conflicts of interest may also arise when the Sub-Adviser invests one or more of its client accounts in different or multiple parts of the same issuer’s capital structure, including investments in public versus private securities, debt versus equity, or senior versus junior/subordinated debt, or otherwise where there are different or inconsistent rights or benefits. Decisions or actions such as investing, trading, proxy voting, exercising, waiving or amending rights or covenants, workout activity, or serving on a board, committee or other involvement in governance may result in conflicts of interest between clients holding different securities or investments. Generally, individual portfolio managers will seek to act in a manner that they believe serves the best interest of the accounts they manage. In cases where a portfolio manager or team faces a conflict among its client accounts, it will seek to act in a manner that it believes best reflects its overall fiduciary duty, which may result in relative advantages or disadvantages for particular accounts.

Nuveen Asset Management has adopted certain compliance procedures which are designed to address these types of conflicts common among investment managers. However, there is no guarantee that such procedures will detect each and every situation in which a conflict arises.

Nuveen Asset Management or its affiliates, including TIAA, sponsor an array of financial products for retirement and other investment goals, and provide services worldwide to a diverse customer base. Accordingly, from time to time, a Fund may be restricted from purchasing or selling securities, or from engaging in other investment activities because of regulatory, legal or contractual restrictions that arise due to another client account’s investments and/or the internal policies of Nuveen Asset Management, TIAA or its affiliates designed to comply with such restrictions. As a result, there may be periods, for example, when Nuveen Asset Management will not initiate or recommend certain types of transactions in certain securities or instruments with respect to which investment limits have been reached.

The investment activities of Nuveen Asset Management or its affiliates may also limit the investment strategies and rights of the Funds. For example, in certain circumstances where the Funds invest in securities issued by companies that operate in certain regulated industries, in certain emerging or international markets, or are subject

to corporate or regulatory ownership definitions, or invest in certain futures and derivative transactions, there may be limits on the aggregate amount invested by Nuveen Asset Management or its affiliates for the Funds and other client accounts that may not be exceeded without the grant of a license or other regulatory or corporate consent. If certain aggregate ownership thresholds are reached or certain transactions undertaken, the ability of Nuveen Asset Management, on behalf of the Funds or other client accounts, to purchase or dispose of investments or exercise rights or undertake business transactions may be restricted by regulation or otherwise impaired. As a result, Nuveen Asset Management, on behalf of the Funds or other client accounts, may limit purchases, sell existing investments, or otherwise restrict or limit the exercise of rights (including voting rights) when Nuveen Asset Management, in its sole discretion, deems it appropriate in light of potential regulatory or other restrictions on ownership or other consequences resulting from reaching investment thresholds.

Fund Manager Compensation

As of the most recently completed fiscal year end, the primary Portfolio Manager’s compensation is as follows:

Portfolio manager compensation consists primarily of base salary and variable components consisting of (i) a cash bonus; (ii) a long-term performance award; and (iii) participation in a profits interest plan.

Base salary . A portfolio manager’s base salary is determined based upon an analysis of the portfolio manager’s general performance, experience and market levels of base pay for such position.

Cash bonus . A portfolio manager is eligible to receive an annual cash bonus that is based on three variables: risk-adjusted investment performance relative to benchmark generally measured over the most recent one, three and five year periods (unless the portfolio manager’s tenure is shorter), ranking versus Morningstar peer funds generally measured over the most recent one, three and five year periods (unless the portfolio manager’s tenure is shorter), and management and peer reviews.

Long-term performance award . A portfolio manager is eligible to receive a long-term performance award that vests after three years. The amount of the award when granted is based on the same factors used in determining the cash bonus. The value of the award at the completion of the three-year vesting period is adjusted based on the risk-adjusted investment performance of Fund(s) managed by the portfolio manager during the vesting period and the performance of the TIAA organization as a whole.

Profits interest plan . Portfolio managers are eligible to receive profits interests in Nuveen Asset Management and its affiliate, Teachers Advisors, LLC, which vest over time and entitle their holders to a percentage of the firms’ annual profits. Profits interests are allocated to each portfolio manager based on such person’s overall contribution to the firms.

There are generally no differences between the methods used to determine compensation with respect to the Fund and the Other Accounts shown in the table above.
