COHEN & STEERS CLOSED-END OPPORTUNITY FUND, INC.

To Our Shareholders:

We would like to share with you our report for the six months ended June 30, 2024. The total returns for Cohen & Steers Closed-End Opportunity Fund, Inc. (the Fund) and its comparative benchmarks were:

The performance data quoted represent past performance. Past performance is no guarantee of future results. The investment return and the principal value of an investment will fluctuate and shares, if sold, may be worth more or less than their original cost. Current performance may be lower or higher than the performance data quoted. Current total returns of the Fund can be obtained by visiting our website at cohenandsteers.com. The Fund’s returns assume the reinvestment of all dividends and distributions at prices obtained under the Fund’s dividend reinvestment plan. Net asset value (NAV) returns reflect fee waivers and/or expense reimbursements, without which the returns would be lower. Index performance does not reflect the deduction of any fees, taxes or expenses. An investor cannot invest directly in an index. Performance figures for periods shorter than one year are not annualized.

Managed Distribution Policy

The Fund, acting in accordance with an exemptive order received from the U.S. Securities and Exchange Commission (SEC) and with approval of its Board of Directors (the Board), adopted a managed distribution policy under which the Fund intends to include long-term capital gains, where applicable, as part of the regular monthly cash distributions to its shareholders (the Plan). The Plan gives the Fund greater flexibility to realize long-term capital gains and to distribute those gains on a regular monthly basis. In accordance with the Plan, the Fund currently distributes $0.087 per share on a monthly basis.

The Fund may pay distributions in excess of the Fund’s investment company taxable income and net realized gains. This excess would be a return of capital distributed from the Fund’s assets. Distributions of capital decrease the Fund’s total assets and, therefore, could have the effect of increasing the Fund’s expense ratio. In addition, in order to make these distributions, the Fund may have to sell portfolio securities at a less than opportune time.

COHEN & STEERS CLOSED-END OPPORTUNITY FUND, INC.

Shareholders should not draw any conclusions about the Fund’s investment performance from the amount of these distributions or from the terms of the Fund’s Plan. The Fund’s total return based on NAV is presented in the table above as well as in the Financial Highlights table.

The Plan provides that the Board may amend or terminate the Plan at any time without prior notice to Fund shareholders; however, at this time, there are no reasonably foreseeable circumstances that might cause the termination. The termination of the Plan could have the effect of creating a trading discount (if the Fund’s stock is trading at or above NAV) or widening an existing trading discount.

Market Review

Closed-end funds rose in the six months ended June 30, 2024, buoyed by strong returns from equities and, to a lesser degree, fixed income.

Economic growth in most major markets exceeded expectations and progress on disinflation slowed. Interest rates rose as a result, and expectations of the magnitude of central bank rate cuts were reduced. Some major central banks, including the European Central Bank and Bank of Canada, modestly cut rates in June, while the Federal Reserve signaled that its first rate reduction in this cycle was likely to occur in the fourth quarter, at the earliest, and would be data-dependent. While returns for U.S. Treasuries and longer-term investment-grade bonds were negative, credit spreads narrowed, which benefited the more credit-sensitive fixed income categories.

Global equities recorded strong gains in the period, led by robust performance in the U.S., with several key indexes reaching record highs. The rapidly expanding growth of artificial intelligence (AI) applications provided a significant tailwind for select sectors. Generally healthy corporate earnings and encouraging macroeconomic data aided stocks. However, sticky inflation and the persistence of elevated interest rates weighed on certain sectors.

Discounts to NAV on closed-end funds narrowed in the first half of the year, providing a tailwind for investors. Equity funds traded at an average 5.9% discount to NAV at the end of the period, compared to 8.2% at the start of the year. Taxable fixed-income funds ended the period at a 0.5% premium to NAV, up from a discount of 4.1%. Municipal bond funds, which tend to hold longer-duration securities, saw the average discount decline to 8.5% from 13.0%.

Fund Performance

The portfolio had a positive total return in the period and outperformed its benchmark on both a market price and net asset value basis.

Within the equity category, fund selection in U.S. general equity funds and option income funds were top contributors to relative performance. An overweight allocation to MLP funds (which benefited from healthy energy demand) and underweights to utilities and real estate funds (which trailed other equities as investors embraced risk in the period) also contributed to relative performance.

An underweight allocation in U.S. hybrid funds detracted from relative performance; the Fund favored other types of equity funds that appeared to offer better relative value. An underweight and fund selection in global equity funds also detracted from relative returns. Likewise, fund selection in the precious metals–oriented single commodity funds category hindered relative performance. However, the adverse effect of the Fund’s selection in single commodity funds was partially offset by a favorable overweight allocation to diversified commodity funds.

COHEN & STEERS CLOSED-END OPPORTUNITY FUND, INC.

Among fixed income closed-end funds, the Fund’s selection and underweight allocation in U.S. multi-sector bond funds and selection in global income funds were important contributors to relative performance. Other contributors included having no investment in short-duration bond funds and an underweight allocation to U.S. high-yield bond funds, both of which trailed other fixed income categories. The Fund’s non-investment in collateralized loan funds, underweight in preferred securities funds and selection in bank loan funds detracted from relative performance.

Note 1. Organization and Significant Accounting Policies

Cohen & Steers Closed-End Opportunity Fund, Inc. (the Fund) was incorporated under the laws of the State of Maryland on September 14, 2006 and is registered under the Investment Company Act of 1940 (the 1940 Act) as a diversified, closed-end management investment company. The Fund’s investment objective is to achieve total return, consisting of high current income and potential capital appreciation.

The following is a summary of significant accounting policies consistently followed by the Fund in the preparation of its financial statements. The Fund is an investment company and, accordingly, follows the investment company accounting and reporting guidance of the Financial Accounting Standards Board Accounting Standards Codification (ASC) Topic 946—Investment Companies. The accounting policies of the Fund are in conformity with accounting principles generally accepted in the United States of America (GAAP). The preparation of the financial statements in accordance with GAAP requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities at the date of the financial statements and the reported amounts of income and expenses during the reporting period. Actual results could differ from those estimates.

Portfolio Valuation: Investments in securities that are listed on the New York Stock Exchange (NYSE) are valued, except as indicated below, at the last sale price reflected at the close of the NYSE on the business day as of which such value is being determined. If there has been no sale on such day, the securities are valued at the mean of the closing bid and ask prices on such day or, if no ask price is available, at the bid price.

Securities not listed on the NYSE but listed on other domestic or foreign securities exchanges are valued in a similar manner. Securities traded on more than one securities exchange are valued at the last sale price reflected at the close of the exchange representing the principal market for such securities on the business day as of which such value is being determined. If after the close of a foreign market, but prior to the close of business on the day the securities are being valued, market conditions change significantly, certain non-U.S. equity holdings may be fair valued pursuant to procedures established by the Board of Directors.

Readily marketable securities traded in the OTC market, including listed securities whose primary market is believed by Cohen & Steers Capital Management, Inc. (the investment manager) to be OTC, are valued on the basis of prices provided by a third-party pricing service or third-party broker-dealers when such prices are believed by the investment manager, pursuant to delegation by the Board of Directors, to reflect the fair value of such securities.

Short-term debt securities with a maturity date of 60 days or less are valued at amortized cost, which approximates fair value. Investments in open-end mutual funds and closed-end interval funds are valued at net asset value (NAV).

The Board of Directors has designated the investment manager as the Fund’s “Valuation Designee” under Rule 2a-5 under the 1940 Act. As Valuation Designee, the investment manager is authorized to make fair valuation determinations, subject to the oversight of the Board of Directors. The investment manager has established a valuation committee (Valuation Committee) to administer, implement and oversee the fair valuation process according to the policies and procedures approved

17

COHEN & STEERS CLOSED-END OPPORTUNITY FUND, INC.

NOTES TO FINANCIAL STATEMENTS (Unaudited)—(Continued)

annually by the Board of Directors. Among other things, these procedures allow the Fund to utilize independent pricing services, quotations from securities and financial instrument dealers and other market sources to determine fair value.

Securities for which market prices are unavailable, or securities for which the investment manager determines that the bid and/or ask price or a counterparty valuation does not reflect market value, will be valued at fair value, as determined in good faith by the Valuation Committee, pursuant to procedures approved by the Fund’s Board of Directors. Circumstances in which market prices may be unavailable include, but are not limited to, when trading in a security is suspended, the exchange on which the security is traded is subject to an unscheduled close or disruption or material events occur after the close of the exchange on which the security is principally traded. In these circumstances, the Fund determines fair value in a manner that fairly reflects the market value of the security on the valuation date based on consideration of any information or factors it deems appropriate. These may include, but are not limited to, recent transactions in comparable securities, information relating to the specific security and developments in the markets.

Foreign equity fair value pricing procedures utilized by the Fund may cause certain non-U.S. equity holdings to be fair valued on the basis of fair value factors provided by a pricing service to reflect any significant market movements between the time the Fund values such securities and the earlier closing of foreign markets.

The Fund’s use of fair value pricing may cause the NAV of Fund shares to differ from the NAV that would be calculated using market quotations. Fair value pricing involves subjective judgments and it is possible that the fair value determined for a security may be materially different than the value that could be realized upon the sale of that security.

Fair value is defined as the price that the Fund would expect to receive upon the sale of an investment or expect to pay to transfer a liability in an orderly transaction with an independent buyer in the principal market or, in the absence of a principal market, the most advantageous market for the investment or liability. The hierarchy of inputs that are used in determining the fair value of the Fund’s investments is summarized below.

The inputs or methodology used for valuing investments may or may not be an indication of the risk associated with those investments. Changes in valuation techniques may result in transfers into or out of an assigned level within the disclosure hierarchy.

18

COHEN & STEERS CLOSED-END OPPORTUNITY FUND, INC.

NOTES TO FINANCIAL STATEMENTS (Unaudited)—(Continued)

The following is a summary of the inputs used as of June 30, 2024 in valuing the Fund’s investments carried at value:

Security Transactions and Investment Income: Security transactions are recorded on trade date. Realized gains and losses on investments sold are recorded on the basis of identified cost. Interest income, which includes the amortization of premiums and accretion of discounts, is recorded on the accrual basis. Dividend income is recorded on the ex-dividend date, except for certain dividends on foreign securities, which are recorded as soon as the Fund is informed after the ex-dividend date. Distributions from closed-end funds (CEFs) and exchange-traded funds (ETFs) are recorded as ordinary income, net realized capital gain or return of capital based on information reported by the CEFs and ETFs and management’s estimates of such amounts based on historical information. These estimates are adjusted when the actual source of distributions is disclosed by the CEFs and ETFs and may differ from the estimated amounts.

Foreign Currency Translation: The books and records of the Fund are maintained in U.S. dollars. Investment securities and other assets and liabilities denominated in foreign currencies are translated into U.S. dollars based upon prevailing exchange rates on the date of valuation. Purchases and sales of investment securities and income and expense items denominated in foreign currencies are translated into U.S. dollars based upon prevailing exchange rates on the respective dates of such transactions.

19

COHEN & STEERS CLOSED-END OPPORTUNITY FUND, INC.

NOTES TO FINANCIAL STATEMENTS (Unaudited)—(Continued)

The Fund does not isolate that portion of the results of operations resulting from fluctuations in foreign exchange rates on investments from the fluctuations arising from changes in market prices of securities held. Such fluctuations are included with the net realized and unrealized gain or loss on investments.

Net realized foreign currency transaction gains or losses arise from sales of foreign currencies, (excluding gains and losses on forward foreign currency exchange contracts, which are presented separately, if any), currency gains or losses realized between the trade and settlement dates on securities transactions, and the difference between the amounts of dividends, interest, and foreign withholding taxes recorded on the Fund’s books and the U.S. dollar equivalent of the amounts actually received or paid. Net unrealized foreign currency translation gains and losses arise from changes in the values of assets and liabilities, other than investments in securities, on the date of valuation, resulting from changes in exchange rates. Pursuant to U.S. federal income tax regulations, certain foreign currency gains/losses included in realized and unrealized gains/losses are included in or are a reduction of ordinary income for federal income tax purposes.

Dividends and Distributions to Shareholders: Dividends from net investment income and capital gain distributions are determined in accordance with U.S. federal income tax regulations, which may differ from GAAP. Dividends from net investment income, if any, are typically declared quarterly and paid monthly. Net realized capital gains, unless offset by any available capital loss carryforward, are typically distributed to shareholders at least annually. Dividends and distributions to shareholders are recorded on the ex-dividend date and are automatically reinvested in full and fractional shares of the Fund in accordance with the Fund’s dividend reinvestment plan, unless the shareholder has elected to have them paid in cash.

The Fund has a managed distribution policy in accordance with exemptive relief issued by the U.S. Securities and Exchange Commission (SEC). The Plan gives the Fund greater flexibility to realize long-term capital gains throughout the year and to distribute those gains on a more regular basis to shareholders. Therefore, regular monthly distributions throughout the year may include a portion of estimated realized long-term capital gains, along with net investment income, short-term capital gains and return of capital, which is not taxable. In accordance with the Plan, the Fund is required to adhere to certain conditions in order to distribute long-term capital gains during the year.

Dividends from net investment income are subject to recharacterization for tax purposes. Based upon the results of operations for the six months ended June 30, 2024 the investment manager considers it likely that a portion of the dividends will be reclassified to distributions from tax return of capital upon the final determination of the Fund’s taxable income after December 31, 2024, the Fund’s fiscal year end.

Distributions Subsequent to June 30, 2024: The following distributions have been declared by the Fund’s Board of Directors and are payable subsequent to the period end of this report.

Income Taxes: It is the policy of the Fund to continue to qualify as a regulated investment company (RIC), if such qualification is in the best interest of the shareholders, by complying with the requirements of Subchapter M of the Internal Revenue Code applicable to RICs, and by distributing substantially all of its taxable earnings to its shareholders. Also, in order to avoid the payment of any federal excise taxes, the Fund will distribute substantially all of its net investment income and net realized gains on a calendar year basis. Accordingly, no provision for federal income or excise tax is necessary. Management has analyzed the Fund’s tax positions taken on federal and applicable state income tax returns as well as its tax positions in non-U.S. jurisdictions in which it trades for all open tax years and has concluded that as of June 30, 2024, no additional provisions for income tax are required in the Fund’s financial statements. The Fund’s tax positions for the tax years for which the applicable statutes of limitations have not expired are subject to examination by the Internal Revenue Service, state departments of revenue and by foreign tax authorities.

Note 2. Investment Management Fees and Other Transactions with Affiliates

Investment Management Fees: Cohen & Steers Capital Management, Inc. serves as the Fund’s investment manager pursuant to an investment management agreement (the investment management agreement). Under the terms of the investment management agreement, the investment manager provides the Fund with day-to-day investment decisions and generally manages the Fund’s investments in accordance with the stated policies of the Fund, subject to the supervision of the Board of Directors.

For the services provided to the Fund, the investment manager receives a fee, accrued daily and paid monthly, at the annual rate of 0.95% of the average daily net assets of the Fund.

The investment manager is also responsible, under the investment management agreement, for the performance of certain administrative functions for the Fund. Additionally, the investment manager pays certain expenses of the Fund, including, but not limited to, administrative and custody fees, transfer agent fees, professional fees, and reports to shareholders.

The investment manager has contractually agreed to reimburse the Fund so that its total annual operating expenses (exclusive of brokerage fees and commissions, taxes, and upon approval of the Board of Directors, extraordinary expenses) do not exceed 0.95% of the Fund’s average daily net assets of the Fund. This commitment is currently expected to remain in place for the life of the Fund, can only be amended or terminated by agreement of the Fund’s Board of Directors and the investment manager and will terminate automatically in the event of termination of the investment management agreement between the investment manager and the Fund. For the six months ended June 30, 2024, fees waived and/or expenses reimbursed totaled $7,348.

Directors’ and Officers’ Fees: Certain directors and officers of the Fund are also directors, officers and/or employees of the investment manager. The Fund does not pay compensation to directors and officers affiliated with the investment manager except for the Chief Compliance Officer, who received compensation from the investment manager, which was reimbursed by the Fund, in the amount of $3,543 for the six months ended June 30, 2024.

Note 3. Purchases and Sales of Securities

Purchases and sales of securities, excluding short-term investments, for the six months ended June 30, 2024, totaled $47,336,708 and $51,792,803, respectively.

Note 4. Income Tax Information

As of June 30, 2024, the federal tax cost and net unrealized appreciation (depreciation) in value of investments held were as follows:

As of December 31, 2023, the Fund has a net capital loss carryforward of $12,772,892 which may be used to offset future capital gains. The loss is comprised of a short-term capital loss carryforward of $4,192,782 and a long-term capital loss carryforward of $8,580,110, which under current federal income tax rules, may offset capital gains recognized in any future period.

Note 5. Capital Stock

The Fund is authorized to issue 100 million shares of common stock at a par value of $0.001 per share.

During the six months ended June 30, 2024, the Fund issued 61,936 shares of common stock at $698,346 for the reinvestment of dividends. During the year ended December 31, 2023, the Fund issued 113,697 shares of common stock at $1,210,443 for the reinvestment of dividends.

On December 12, 2023, the Board of Directors approved the continuation of the delegation of its authority to management to effect repurchases, pursuant to management’s discretion and subject to market conditions and investment considerations, of up to 10% of the Fund’s common shares outstanding as of January 1, 2024 through December 31, 2024.

During the six months ended June 30, 2024 and the year ended December 31, 2023, the Fund did not effect any repurchases.

Note 6. Other Risks

Market Price Discount from Net Asset Value Risk: Shares of closed-end investment companies frequently trade at a discount from their NAV. This characteristic is a risk separate and distinct from the risk that NAV could decrease as a result of investment activities. Whether investors will realize gains or losses upon the sale of the shares will depend not upon the Fund’s NAV but entirely upon whether the market price of the shares at the time of sale is above or below the investor’s purchase price for the shares. Because the market price of the shares is determined by factors such as relative supply of and demand for shares in the market, general market and economic conditions, and other factors beyond the control of the Fund, the shares may trade at, above or below NAV.

22

COHEN & STEERS CLOSED-END OPPORTUNITY FUND, INC.

NOTES TO FINANCIAL STATEMENTS (Unaudited)—(Continued)

Investing in Other Investment Companies Risk: Since the Fund concentrates its assets in closed-end management investment companies, risks of investing in the Fund include the risks associated with the purchased closed-end investment companies’ portfolio securities, and a shareholder in the Fund will bear not only his or her proportionate share of the Fund’s expenses, but also indirectly the expenses of the purchased closed-end investment companies (Portfolio Funds). Shareholders will therefore be subject to duplicative expenses to the extent the Fund invests in other investment companies. Risks associated with investments in closed-end funds generally include market risk, leverage risk, risk of market price discount from NAV, risk of anti-takeover provisions and non-diversification.

To the extent the Fund invests a portion of its assets in other investment companies, including open-end funds, exchange-traded funds and other types of pooled investment funds, those assets will be subject to the risks of the purchased investment fund’s portfolio securities, and a shareholder in the Fund will bear not only his or her proportionate share of the Fund’s expenses, but also indirectly the expenses of the purchased investment funds. In addition, restrictions under the 1940 Act may limit the Fund’s ability to invest in other investment companies to the extent desired.

Sector Concentration Risk: Some Portfolio Funds invest substantially, or even exclusively, in one sector or industry group and therefore carry risk of the particular sector or industry group. To the extent a Portfolio Fund focuses its investments in a specific sector, such as real estate, energy or utilities, the Portfolio Fund will be susceptible to adverse conditions and economic or regulatory occurrences affecting the sector or industry group, which tends to increase volatility and result in higher risk.

Covered Call Writing Risk: The Fund may invest in Portfolio Funds that engage in a strategy known as “covered call option writing,” which is designed to produce income from option premiums and offset a portion of a market decline in the underlying security. The writer (seller) of a covered call option forgoes, during the option’s life, the opportunity to profit from increases in the market value of the security covering the call option above the sum of the premium and the strike price of the call, but has retained the risk of loss should the price of the underlying security decline. The writer of an option has no control over the time when it may be required to fulfill its obligation as a writer of the option. Once an option writer has received an exercise notice, it cannot effect a closing purchase transaction in order to terminate its obligation under the option and must deliver the underlying security at the exercise price.

Municipal Bond Risk: The Fund may invest in Portfolio Funds that invest in municipal bonds. Municipal bonds are debt obligations issued by states or by political subdivisions or authorities of states. Municipal bonds are typically designated as general obligation bonds, which are general obligations of a governmental entity that are backed by the taxing power of such entity, or revenue bonds, which are payable from the income of a specific project or authority and are not supported by the issuer’s power to levy taxes. Municipal bonds are long-term fixed rate debt obligations that generally decline in value with increases in interest rates, when an issuer’s financial condition worsens or when the rating on a bond is decreased. Many municipal bonds may be called or redeemed prior to their stated maturity. Lower quality revenue bonds and other credit-sensitive municipal securities carry higher risks of default than general obligation bonds.

Master Limited Partnership Risk: The Fund may invest in Portfolio Funds that invest in master limited partnerships (MLPs). An investment in MLP units involves some risks that differ from an

23

COHEN & STEERS CLOSED-END OPPORTUNITY FUND, INC.

NOTES TO FINANCIAL STATEMENTS (Unaudited)—(Continued)

investment in the common stock of a corporation. Holders of MLP units have limited control on matters affecting the partnership. Investing in MLPs involves certain risks related to investing in the underlying assets of the MLPs and risks associated with pooled investment vehicles. MLPs holding credit-related investments are subject to interest rate risk and the risk of default on payment obligations by debt issuers. MLPs that concentrate in a particular industry or a particular geographic region are subject to risks associated with such industry or region. The benefit derived from the Fund’s investment in MLPs is largely dependent on the MLPs being treated as partnerships for federal income tax purposes. Weakening energy market fundamentals may increase counterparty risk and impact MLP profitability. Specifically, energy companies suffering financial distress may be able to abrogate contracts with MLPs, decreasing or eliminating sources of revenue.

Senior Loans Risk: The Fund may invest in Portfolio Funds that invest in senior loans. The risks associated with senior loans are similar to the risks of junk bonds, although senior loans are typically senior and secured, whereas junk bonds are often subordinated and unsecured. Investments in senior loans are typically below investment grade and are considered speculative because of the credit risk of their issuers. Such companies are more likely to default on their payments of interest and principal owed, and such defaults could reduce a Portfolio Fund’s NAV and income distributions. An economic downturn generally leads to a higher non-payment rate, and a senior loan may lose significant value before a default occurs. There is no assurance that the liquidation of the collateral would satisfy the claims of the borrower’s obligations in the event of the nonpayment of scheduled interest or principal, or that the collateral could be readily liquidated. Economic and other events (whether real or perceived) can reduce the demand for certain senior loans or senior loans generally, which may reduce market prices. Senior loans and other debt securities are also subject to the risk of price declines and to increases in prevailing interest rates, although floating-rate debt instruments such as senior loans in which certain Portfolio Funds may be expected to invest are substantially less exposed to this risk than fixed-rate debt instruments.

Preferred Securities Risk: The Fund may invest in Portfolio Funds that invest in preferred securities. Preferred securities are subject to credit risk, which is the risk that a security will decline in price, or the issuer of the security will fail to make dividend, interest or principal payments when due, because the issuer experiences a decline in its financial status. Preferred securities are also subject to interest rate risk and may decline in value because of changes in market interest rates. The Fund may be subject to a greater risk of rising interest rates than would normally be the case in an environment of low interest rates and the effect of potential government fiscal policy initiatives and resulting market reaction to those initiatives. In addition, an issuer may be permitted to defer or omit distributions. Preferred securities are also generally subordinated to bonds and other debt instruments in a company’s capital structure. During periods of declining interest rates, an issuer may be able to exercise an option to redeem (call) its issue at par earlier than scheduled, and the Fund may be forced to reinvest in lower yielding securities. Certain preferred securities may be substantially less liquid than many other securities, such as common stocks. Generally, preferred security holders have no voting rights with respect to the issuing company unless certain events occur. Certain preferred securities may give the issuers special redemption rights allowing the securities to be redeemed prior to a specified date if certain events occur, such as changes to tax or securities laws.

24

COHEN & STEERS CLOSED-END OPPORTUNITY FUND, INC.

NOTES TO FINANCIAL STATEMENTS (Unaudited)—(Continued)

Leverage Risk: Portfolio Funds may employ the use of leverage. The use of leverage is a speculative technique and there are special risks and costs associated with leverage. The NAV of the Portfolio Fund’s shares may be reduced by the issuance and ongoing costs of leverage. So long as the Portfolio Fund is able to invest in securities that produce an investment yield that is greater than the total cost of leverage, the leverage strategy will produce higher current net investment income for the shareholders, including the Fund. On the other hand, to the extent that the total cost of leverage exceeds the incremental income gained from employing such leverage, shareholders, including the Fund, would realize lower net investment income. In addition to the impact on net income, the use of leverage will have an effect of magnifying capital appreciation or depreciation for shareholders. Specifically, in an up market, leverage will typically generate greater capital appreciation than if the Portfolio Fund were not employing leverage. Conversely, in down markets, the use of leverage will generally result in greater capital depreciation than if the Portfolio Fund had been unlevered. To the extent that the Portfolio Fund is required or elects to reduce its leverage, the Portfolio Fund may need to liquidate investments, including under adverse economic conditions which may result in capital losses potentially reducing returns to shareholders. The use of leverage may also result in the investment advisory fees payable to a Portfolio Fund’s investment adviser being higher than if the Portfolio Fund did not use leverage and can increase operating costs, which may reduce total return. There can be no assurance that a leveraging strategy will be successful during any period in which it is employed.

Foreign (Non-U.S.) Securities Risk: Some of the securities held by certain of the Portfolio Funds may be issued by foreign issuers. Risks of investing in foreign securities include currency risks, future political and economic developments and possible imposition of foreign withholding taxes on income or proceeds payable on the securities. In addition, there may be less publicly available information about a foreign issuer than about a domestic issuer, and foreign issuers may not be subject to the same accounting, auditing and financial recordkeeping standards and requirements as domestic issuers. Moreover, securities of many foreign issuers and their markets may be less liquid and their prices more volatile than securities of comparable U.S. issuers.

Investing in securities of companies in emerging markets may entail special risks relating to potential economic, political or social instability and the risks of expropriation, nationalization, confiscation, trade sanctions or embargoes or the imposition of restrictions on foreign investment, the lack of hedging instruments, and repatriation of capital invested. The securities and real estate markets of some emerging market countries have in the past experienced substantial market disruptions and may do so in the future.

Geopolitical Risk: Geopolitical events, such as war (including Russia’s military invasion of Ukraine), terrorist attacks, natural or environmental disasters, country instability, public health emergencies (including epidemics and pandemics), market instability, debt crises and downgrades, embargoes, tariffs, sanctions and other trade barriers and other governmental trade or market control programs, the potential exit of a country from its respective union (such as Brexit) and related geopolitical events, have led and may in the future lead to market volatility and have long-lasting impacts on U.S. and global economies and financial markets. Supply chain disruptions or significant changes in the supply or prices of commodities or other economic inputs may have material and unexpected effects on both global securities markets and individual countries, regions, sectors, companies or industries. Events occurring in one region of the world may negatively impact industries and regions that are not otherwise

directly impacted by the events. Additionally, those events, as well as other changes in foreign and domestic political and economic conditions, could adversely affect individual issuers or related groups of issuers, securities markets, interest rates, secondary trading, credit ratings, inflation, investor sentiment and other factors affecting the value of the Fund’s investments.

Russia’s military invasion of Ukraine has significantly amplified already existing geopolitical tensions. The United States and many other countries have instituted various economic sanctions against Russia, Russian individuals and entities and Belarus. The extent and duration of the military action, sanctions imposed and other punitive actions taken (including any Russian retaliatory responses to such sanctions and actions), and resulting disruptions in Europe and globally cannot be predicted, but could be significant and have a severe adverse effect on the global economy, securities markets and commodities markets globally, including through global supply chain disruptions, increased inflationary pressures and reduced economic activity. Ongoing conflicts in the Middle East could have similar negative impacts.

Systemic risk events in the financial sectors and/or resulting government actions can negatively impact the Fund. For example, issues with certain regional U.S. banks and other financial institutions in March 2023 raised economic concerns over disruption in the U.S. banking system. These risks also may adversely affect financial intermediaries, such as clearing agencies, clearing houses, banks, securities firms, and exchanges, with which the Fund interacts. There can be no certainty that any actions taken by the U.S. government to strengthen public confidence in the U.S. banking system or financial markets will be effective in mitigating the effects of financial institution failures on the economy and restoring or maintaining public confidence. The strengthening or weakening of the U.S. dollar relative to other currencies may, among other things, adversely affect the Fund’s investments denominated in non-U.S. dollar currencies. It is difficult to predict when similar events affecting the U.S. or global financial markets may occur, the effects that such events may have, and the duration of those effects.

The rapid development and increasingly widespread use and regulation of artificial intelligence, including machine learning technology and generative artificial intelligence such as ChatGPT (collectively, AI Technologies), may pose risks to the Fund. For instance, the global economy may be significantly disrupted or otherwise adversely impacted by the rapid advanced development of AI Technologies and by efforts to regulate or control its use and advancement. The legal and regulatory frameworks within which AI Technologies operate continue to rapidly evolve, and it is not possible to predict the full extent of current or future risks related thereto.

Some political leaders around the world (including in the U.S. and certain European nations) have been elected on protectionist platforms, raising questions about the future of global free trade. Global trade disruption, significant introductions of trade barriers and bilateral trade frictions, together with any future downturns in the global economy resulting therefrom, could adversely affect the financial performance of the Fund and its investments.

Regulatory Risk: Legal and regulatory developments may adversely affect the Fund. The regulatory environment for the Fund is evolving, and changes in the regulation of investment funds and other financial institutions or products (such as banking or insurance products), and their trading activities and capital markets, or a regulator’s disagreement with the Fund’s interpretation of the application of certain regulations, may adversely affect the ability of the Fund to pursue its investment

strategy, its ability to obtain leverage and financing, and the value of investments held by the Fund. The U.S. government has proposed and adopted multiple regulations that could have a long-lasting impact on the Fund and on the fund industry in general.

In May 2024, the standard settlement cycle for numerous types of U.S. securities, including Fund shares and many of the securities the Fund invests in, moved from two business days after the transaction date (T+2) to the next business day after the transaction date (T+1). This reduced settlement cycle may result in additional risks and costs to the Fund, including increased operational risks associated with the resolution of trade breaks and exceptions. These risks will be heightened in light of certain Fund investments (such as certain non-U.S. securities) that have longer settlement cycles than is expected of Fund shares.

Additional legislative or regulatory actions to address perceived liquidity or other issues in markets generally, or in particular markets such as the fixed income securities markets and municipal securities markets, may alter or impair certain market participants’ ability to utilize certain investment strategies and techniques.

The Fund and the instruments in which it invests may be subject to new or additional regulatory constraints in the future. While the full extent of all of these regulations is still unclear, these regulations and actions may adversely affect both the Fund and the instruments in which the Fund invests and its ability to execute its investment strategy. For example, climate change regulation (such as decarbonization legislation, other mandatory controls to reduce emissions of greenhouse gases, or related disclosure requirements) could significantly affect the Fund or its investments by, among other things, increasing compliance costs or underlying companies’ operating costs and capital expenditures. Similarly, regulatory developments in other countries may have an unpredictable and adverse impact on the Fund.

Note 7. Other

In the normal course of business, the Fund enters into contracts that provide general indemnifications. The Fund’s maximum exposure under these arrangements is dependent on claims that may be made against the Fund in the future and, therefore, cannot be estimated; however, based on experience, the risk of material loss from such claims is considered remote.

Note 8. Subsequent Events

Management has evaluated events and transactions occurring after June 30, 2024 through the date that the financial statements were issued, and has determined that no additional disclosure in the financial statements is required.
