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, 2026. The total returns for the 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.

(a)

As a closed-end investment company, the price of the Fund's exchange-traded shares will be set by market forces and can deviate from the NAV per share of the Fund.

(b)

The returns shown are based on NAVs reported on June 30, 2026 and may differ from the returns shown in the Financial Highlights, which reflect adjustments made to the NAVs in accordance with accounting principles generally accepted in the United States of America (GAAP).

(c)

The S&P 500 Index is an unmanaged index of 500 large-capitalization stocks that is frequently used as a general measure of U.S. stock market performance. The S-Network All Taxable ex-Foreign plus Capped Municipal CEF Index is a market capitalization-weighted index comprising all taxable closed-end funds and diversified municipal bond funds, except for single-country funds and region-specific equity funds. The index reconstitutes and rebalances quarterly.

Cohen & Steers Closed-End Opportunity Fund, Inc.

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.

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 posted positive returns in the six months ended June 30, 2026, despite a market that shifted repeatedly as investors navigated competing economic narratives and more hawkish central bank policy expectations.

The period began with a constructive economic backdrop. Prior to the late-February onset of the U.S.-Iran conflict, economic activity was generally supportive of markets, with easing inflation reinforcing expectations that major central banks would cut interest rates in 2026. This dynamic shifted following the conflict's disruption to seaborne energy flows. Markets were pressured as investors struggled to gauge the likely duration of the conflict, its economic implications and the scope of any resulting monetary policy response. By April, however, sentiment improved as markets began to price in the expectation of a relatively swift resolution of the conflict and as the global economy proved more resilient than feared. Nevertheless, persistent inflation tempered expectations for monetary easing.

In this environment, the three major closed-end fund categories had positive returns, with equity funds being the top performer followed by the tax-free municipal bond group; the taxable fixed income group had a relatively modest gain. With respect to valuations, overall closed-end fund discounts to net asset value widened from -2.8% to -4.6%.

Fund Performance

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

Equity funds had a solid gain as a group, supported by strong corporate earnings that often exceeded analyst expectations. Among sector-specific strategies, master limited partnership (MLP) funds were a positive standout, aided by rising crude oil prices and generally positive company earnings and outlooks. The global hybrid and U.S. hybrid sectors also had large returns. Single-commodity funds, which focus on precious metals, were a notable underperformer, hindered as gold and silver prices declined after surging in 2025. Contributors to the Fund's relative performance within the equities allocation included an overweight in global hybrid funds and an overweight and

fund selection in the U.S. sector equity group. Detractors from relative performance included a non-allocation to global equity funds and fund selection in the option income sector.

Taxable fixed income funds had a positive but lesser return, restrained in some cases by a modest rise in bond yields. Convertible bond funds were the best performers, reflecting their ties to high growth segments of the capital market. Emerging market bond funds also performed well. Conversely, longer-duration sectors that are more sensitive to interest rate changes, including investment-grade and government bond funds, lagged as investors favored credit and equity-linked assets. Within fixed income, the Fund's non-investment in collateralized loan funds aided performance, as the sector had a sizable decline amid concerns about lower-quality lending. An overweight in global income funds detracted within fixed income; the sector had a relatively modest gain in the period.

NOTES TO FINANCIAL STATEMENTS (Unaudited) 

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 over-the-counter (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

18

Cohen & Steers Closed-End Opportunity Fund, Inc.

NOTES TO FINANCIAL STATEMENTS (Unaudited)-(Continued)

procedures approved 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.

•

Level 1-quoted prices in active markets for identical investments

•

Level 2-other significant observable inputs (including quoted prices for similar investments, interest rates, credit risk, etc.)

•

Level 3-significant unobservable inputs (including the Fund's own assumptions in determining the fair value of investments)

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.

The levels associated with valuing the Fund's investments as of June 30, 2026 are disclosed in the Fund's Schedule of Investments.

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

19

Cohen & Steers Closed-End Opportunity Fund, Inc.

NOTES TO FINANCIAL STATEMENTS (Unaudited)-(Continued)

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. 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.

20

Cohen & Steers Closed-End Opportunity Fund, Inc.

NOTES TO FINANCIAL STATEMENTS (Unaudited)-(Continued)

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, 2026, the investment manager considers it likely that a portion of the dividends will be reclassified to distributions from net realized gain upon the final determination of the Fund's taxable income after the Fund's fiscal year end.

Distributions Subsequent to June 30, 2026: The following distributions have been declared by the Fund's Board of Directors and are payable subsequent to the period end of this report.

Ex-Date/
Record Date

Payable Date

Amount
7/14/26 7/31/26 $0.087
8/11/26 8/31/26 $0.087
9/8/26 9/30/26 $0.087

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, 2026, 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.

21

Cohen & Steers Closed-End Opportunity Fund, Inc.

NOTES TO FINANCIAL STATEMENTS (Unaudited)-(Continued)

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, 2026, fees waived and/or expenses reimbursed totaled $8,795.

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 interested directors and officers.

Note 3. Purchases and Sales of Securities

Purchases and sales of securities, excluding short-term investments, for the six months ended June 30, 2026, totaled $140,013,791 and $136,956,941, respectively.

Note 4. Income Tax Information

Cohen & Steers Closed-End Opportunity Fund, Inc.

NOTES TO FINANCIAL STATEMENTS (Unaudited)-(Continued)

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.

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.

Gold, Silver and Other Precious Metals Risk: The Fund may invest in Portfolio Funds that invest in gold, silver and other precious metals. Investments related to gold, silver and other precious metals are considered speculative and are affected by a variety of worldwide economic, financial and political factors. The price of gold, silver and other precious metals may fluctuate sharply over short periods of time due to: changes in inflation or expectations regarding inflation in various countries; the availability of supplies of gold, silver and other precious metals; changes in industrial and commercial demand; gold, silver and other precious metals sales by governments, central banks or international agencies; investment speculation, monetary and other economic policies of various governments; and government restrictions on private ownership of gold, silver and other precious metals. No income is derived from holding physical gold, silver or other precious metals, which is

23

Cohen & Steers Closed-End Opportunity Fund, Inc.

NOTES TO FINANCIAL STATEMENTS (Unaudited)-(Continued)

unlike securities that may pay dividends or make other current payments. Although a Portfolio Fund may have contractual protections with respect to the credit risk of their custodian, gold or silver held in physical form (even in a segregated account) involves the risk of delay in obtaining the assets in the case of bankruptcy or insolvency of the custodian. This could impair disposition of the assets under those circumstances. If a Portfolio Fund holds physical gold or silver, the Portfolio Fund is also subject to an increased risk of loss and expense in connection with the transportation of such assets to and from the Portfolio Fund's custodian. In addition, gains derived from trading in gold and other precious metals may result in negative tax consequences due to appreciation in value, which could limit the ability of a Portfolio Fund to sell its holdings of physical gold or silver at the desired time.

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 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.

24

Cohen & Steers Closed-End Opportunity Fund, Inc.

NOTES TO FINANCIAL STATEMENTS (Unaudited)-(Continued)

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.

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,

25

Cohen & Steers Closed-End Opportunity Fund, Inc.

NOTES TO FINANCIAL STATEMENTS (Unaudited)-(Continued)

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 also results in the investment management fees payable to the investment manager being higher than if the 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.) and Emerging Market 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.

Common Stock Risk: Common stocks are subject to special risks. Although common stocks have historically generated higher average returns than fixed-income securities over the long term, common stocks also have experienced significantly more volatility in returns. Common stocks may be more susceptible to adverse changes in market value due to issuer specific events or general movements in the equities markets. A drop in the stock market may depress the price of common stocks held by the Fund. Common stock prices fluctuate for many reasons, including changes to investors' perceptions of the financial condition of an issuer or the general condition of the relevant stock market, or the occurrence of political or economic events affecting issuers. For example, an adverse event, such as an unfavorable earnings report, may depress the value of common stock in which the Fund has invested; the price of common stock of an issuer may be particularly sensitive to general movements in the stock market; or a drop in the stock market may depress the price of most or all of the common stocks held by the Fund. Also, common stock of an issuer in the Fund's portfolio may decline in price if the issuer fails to make anticipated dividend payments because, among other reasons, the issuer of the security experiences a decline in its financial condition. The common stocks in which the Fund will invest are typically subordinated to preferred securities, bonds and other debt instruments in a company's capital structure in terms of priority to corporate income and assets, and, therefore, will be subject to greater risk than the preferred securities or debt instruments of such issuers. In addition, common stock prices may be sensitive to rising interest rates as the costs of capital rise and borrowing costs increase.

Market Disruption and Geopolitical Risk: Geopolitical and market events (including armed conflicts, terrorism, natural disasters, public health emergencies, trade disputes, tariffs, sanctions, and political or economic instability) can cause significant volatility in global markets and may adversely affect the Fund's investments. Disruptions to supply chains, sharp movements in commodity prices, and changes in investor sentiment or credit conditions may negatively impact issuers, sectors, or entire regions, even those not directly involved in the originating event.

Recent examples include the ongoing conflicts in Ukraine and the Middle East and increasing political polarization around issues such as trade policy, monetary policy and the U.S. debt ceiling. The rapid development and regulation of artificial intelligence technologies may also introduce uncertainty. The scope, severity, and duration of these risks are difficult to predict, but they could materially reduce the value of the Fund's 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. These regulations or any laws and regulations that may be adopted in the future may restrict the Fund's ability to engage in transactions or raise additional capital and/or increase overall expenses of the Fund.

Additional legislative or regulatory actions 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. 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.

Cybersecurity Risk: With the increased use of technologies such as the Internet and artificial intelligence, including machine learning technology and generative artificial intelligence such as ChatGPT and the dependence on computer systems to perform necessary business functions, the Fund and its service providers (including the investment manager), and their own service providers, may be susceptible to operational and information security risks resulting from cyber-attacks and/or other technological malfunctions. In general, cyber-attacks are deliberate, but unintentional events may have similar effects. Cyber-attacks include, among others, stealing or corrupting data maintained online or digitally, preventing legitimate users from accessing information or services on a website or company system, misappropriating or releasing confidential information without authorization (including personal data), gaining unauthorized access to digital systems for purposes

27

Cohen & Steers Closed-End Opportunity Fund, Inc.

NOTES TO FINANCIAL STATEMENTS (Unaudited)-(Continued)

of misappropriating assets and causing operational disruption. Cyber-attacks may also be carried out in a manner that does not require gaining unauthorized access, such as causing denial-of-service. New ways to carry out cyber-attacks continue to develop. There may be an increased risk of cyber-attacks during periods of geopolitical or military conflict, and geopolitical tensions may increase the scale and sophistication of deliberate cyber security attacks, particularly those from nation-states or from entities with nation-state backing. Successful cyber-attacks against, or security breakdowns of, the Fund, the investment manager, or a custodian, transfer agent, or other affiliated or third-party service provider may adversely affect the Fund or its shareholders.

Each of the Fund and the investment manager may have limited ability to detect, prevent or mitigate cyber-attacks or security or technology breakdowns affecting the Fund third-party service providers. While the Fund has established business continuity plans and systems designed to detect, prevent or reduce the impact of cyber-attacks, such plans and systems are subject to inherent limitations.

Note 7. Operating Segments

An operating segment is defined in ASC Topic 280 as a component of a public entity that engages in business activities from which it may recognize revenues and incur expenses, has operating results that are regularly reviewed by the public entity's chief operating decision maker (CODM) to make decisions about resources to be allocated to the segment and assess its performance, and has discrete financial information available. The executive committee of the Fund's investment manager and the Fund's chief executive officer and chief financial officer act as the Fund's CODM. The Fund represents a single operating segment, as the CODM monitors the operating results of the Fund as a whole and the Fund's long-term strategic asset allocation is pre-determined 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 total returns, expense ratios, 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.

Note 8. 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 9. Subsequent Events

Management has evaluated events and transactions occurring after June 30, 2026 through the date that the financial statements were issued, and has determined that no additional disclosure in the financial statements is required.

OTHER INFORMATION

A description of the policies and procedures that the Fund uses to determine how to vote proxies relating to portfolio securities is available (i) without charge, upon request, by calling (866) 227-0757, (ii) on our website at cohenandsteers.com or (iii) on the U.S. Securities and Exchange Commission's (SEC) website at http://www.sec.gov. In addition, the Fund's proxy voting record for the most recent 12-month period ended June 30 is available by August 31 of each year (i) without charge, upon request, by calling (866) 227-0757 or (ii) on the SEC's website at http://www.sec.gov.

Disclosures of the Fund's complete holdings are required to be made monthly on Form N-PORT, with every third month made available to the public by the SEC 60 days after the end of the Fund's fiscal quarter. The Fund's Form N-PORT, is available (i) without charge, upon request, by calling (866) 227-0757 or (ii) on the SEC's website at http://www.sec.gov.

Please note that distributions paid by the Fund to shareholders are subject to recharacterization for tax purposes and are taxable up to the amount of the Fund's net investment company taxable income and net realized gains. Distributions in excess of the Fund's net investment company taxable income and net realized gains are a return of capital distributed from the Fund's assets. To the extent this occurs, the Fund's shareholders of record will be notified of the estimated amount of capital returned to shareholders for each such distribution and this information will also be available at cohenandsteers.com. The final tax treatment of all distributions is reported to shareholders on their 1099-DIV forms, which are mailed after the close of each calendar year. 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.

Notice is hereby given in accordance with Rule 23c-1 under the 1940 Act that the Fund may purchase, from time to time, shares of its common stock in the open market.

Change to the Fund's Chief Compliance Officer

On June 16, 2026, the Board of Directors approved the appointment of Nargis Hilal as the Chief Compliance Officer (CCO) of the Fund effective July 3, 2026. Ms. Hilal previously served as the Fund's Deputy CCO.

Fundamental Investment Policy Change

On June 16, 2026, the Board of Directors approved certain changes to the Fund's 80% investment policy and related investment strategy disclosure. The changes will be effective October 1, 2026 (the "Effective Time").

30

Cohen & Steers Closed-End Opportunity Fund, Inc.

At the Effective Time, the existing 80% policy will be replaced with the following new policy: Under normal circumstances, at least 80% of the Fund's net assets will be invested in common stock or other securities issued by Portfolio Funds which are listed on a U.S. or non-U.S. securities exchange.

Additionally, at the Effective Time the Fund's disclosure will be revised to define "Portfolio Fund" as any closed-end pooled investment vehicle and state that the Fund will consider an investment vehicle to be "closed-end" if it does not offer a daily redemption or repurchase right. As a result of these changes, the Fund will have more flexibility under its 80% policy to invest in a broad range of U.S. and non-U.S. investment vehicles, including vehicles that are not registered under the Investment Company Act of 1940. In connection with the above changes, as of the Effective Time the Fund is adopting the following investment strategy disclosure:

The Fund seeks to achieve its objective by investing in the common stock of closed-end pooled investment vehicles (collectively, Portfolio Funds) selected by the Fund's investment manager that invest significantly in equity securities, income-producing securities or other assets, including precious metals and other commodities, real assets and derivatives. Portfolio Funds may invest in both publicly traded and private investments. Types or categories of Portfolio Funds may include, but are not are limited to, Portfolio Funds that invest in the following asset classes:

•

Bank Loans;

•

Convertible Securities;

•

Commodities;

•

Municipal Securities;

•

Income Securities;

•

High Yield Municipal Securities;

•

MLPs;

•

Option Income/Covered Calls;

•

Preferred Securities;

•

Private Credit;

•

Private Equity;

•

Private Real Estate;

•

REITs and other Real Estate Securities;

•

Short Duration Securities;

•

Single Commodity Precious Metals;

•

Taxable Municipal Securities;

•

U.S. General Equity;

•

U.S. High Yield Securities;

•

U.S. Hybrid;

•

U.S. Multi-Sector Securities;

31

Cohen & Steers Closed-End Opportunity Fund, Inc.

•

U.S. Sector Bond;

•

U.S. Sector Equity;

•

Utilities.

Shares of Portfolio Funds in which the Fund invests will be traded on a U.S. or non-U.S. securities exchange.

Securities and other investments in which Portfolio Funds are expected to focus their investments, along with equity, convertible, preferred and high yield securities and the real estate, energy and utilities sectors, are described with their accompanying risks, under "Principal Risks of the Fund-Portfolio Fund Investment Risk."

Under normal circumstances, at least 80% of the Fund's net assets will be invested in common stock or other securities issued by Portfolio Funds which are listed on a U.S. or non-U.S. securities exchange. The Fund will consider an investment vehicle to be "closed-end" if it does not offer a daily redemption or repurchase right. The Fund is unconstrained from an investment perspective with respect to location of Portfolio Funds (e.g., U.S. or non-U.S.), types of interests purchased by Portfolio Funds (i.e., equity or fixed income), strategy/assets held by Portfolio Funds (e.g., precious metals, municipal securities) and whether a Portfolio Fund purchases publicly or privately offered securities. Although most Portfolio Funds are expected to be registered under the 1940 Act, some will not and therefore will not provide investors, such as the Fund, with the protections of the 1940 Act. The Fund's allocations across different types of Portfolio Funds will vary over time, perhaps significantly. The Fund also has the ability to invest directly in equity, income-producing securities, precious metals and other instruments relating to closed-end funds.

In selecting Portfolio Funds, the investment manager seeks to identify closed-end funds that meet one or more of the following characteristics:

•

strong fundamentals, including ability to meet current and projected future dividend payments out of current income or a combination of current income and realized and unrealized gains, and leverage/risk management, as the investment manager believes that a conservative approach to leverage has the potential to help mitigate the effects of changes in interest rates;

•

relatively high current income;

•

share prices at a discount to net asset value;

•

undervalued funds where recent total return on market price trails recent total return on net asset value;

•

well-regarded asset managers with strong track records managing the asset class(es) in which a Portfolio Fund invests;

•

diversification of sectors and asset classes among the Portfolio Funds;

•

market capitalization generally greater than $200 million; and

•

average daily trading volumes generally greater than $750,000 per day.

There is no requirement that any Portfolio Fund in the Fund's portfolio satisfy all the criteria set forth above, and the investment manager will use its discretion in selecting a portfolio of

32

Cohen & Steers Closed-End Opportunity Fund, Inc.

Portfolio Funds that the investment manager believes will help the Fund achieve its investment objective.

In addition to the criteria set forth above, the investment manager also may invest opportunistically in one or more Portfolio Funds when the investment manager believes a Portfolio Fund's shares are not appropriately priced relative to other comparable funds or the Portfolio Fund's share price does not properly reflect the impact of a corporate event or conditions in the overall securities markets that the investment manager believes will have a positive influence on the Portfolio Fund's share price.

The Fund will be limited by provisions of the 1940 Act that limit the amount the Fund can invest in any one Portfolio Fund to 3% of the Portfolio Fund's total outstanding stock. As a result, the Fund may hold a smaller position in a Portfolio Fund than if it were not subject to this restriction. To comply with provisions of the 1940 Act, on any matter upon which Portfolio Fund stockholders are solicited to vote the investment manager will vote Portfolio Fund shares in the same general proportion as shares held by other stockholders of the Portfolio Fund.

The Fund may invest in securities of other closed-end or open-end funds, including exchange traded funds (ETFs) and funds managed by the investment manager, in accordance with Section 12(d)(1) of the 1940 Act and the rules thereunder, or any exemption granted under the 1940 Act.

The Fund may, but is not required to, use, without limit, various derivatives transactions to seek to generate return, facilitate portfolio management and mitigate risks. Although the Fund's investment manager may seek to use these kinds of transactions to further the Fund's investment objectives, no assurance can be given that they will achieve this result. The Fund may enter into (buy or sell) exchange-listed and over-the-counter put and call options on securities (including securities of investment companies and baskets of securities), indices, and other financial instruments; purchase and sell financial futures contracts and options thereon; enter into various interest rate transactions, such as swaps, caps, floors or collars or credit transactions; equity index, total return and credit default swaps; forward contracts; and structured investments. In addition, the Fund may enter into various currency transactions, such as forward currency contracts, currency futures contracts, currency swaps or options on currency or currency futures. The Fund also may purchase and sell derivative instruments that combine features of these instruments. The Fund may invest in other types of derivatives, structured and similar instruments which are not currently available but which may be developed in the future.

Temporary Defensive Positions. When the investment manager believes that market or general economic conditions justify a temporary defensive position, the Fund may deviate from its investment objectives and invest all or any portion of its assets in investment grade debt securities. In such a case, the Fund may not pursue or achieve its investment objective.

33

Cohen & Steers Closed-End Opportunity Fund, Inc.

APPROVAL OF INVESTMENT MANAGEMENT AGREEMENT

The Board of Directors of the Fund (the Board), including a majority of the Directors who are not parties to the Fund's investment management agreement (the Management Agreement), or interested persons of any such party (the Independent Directors), has the responsibility under the Investment Company Act of 1940 to approve the Fund's Management Agreement for its initial two year term and its continuation annually thereafter at a meeting of the Board called for the purpose of voting on the approval or continuation. The Management Agreement was discussed at a meeting of the Independent Directors, in their capacity as the Contract Review Committee, held on June 2, 2026, and at a meeting of the full Board held on June 16, 2026. The Independent Directors, in their capacity as the Contract Review Committee, also discussed the Management Agreement in executive sessions on June 2, 15 and 16, 2026. At the meeting of the full Board on June 16, 2026, the Management Agreement was unanimously continued for a term ending June 30, 2027, by the Board, including the Independent Directors. The Independent Directors were represented by independent counsel who assisted them in their deliberations during the meetings and executive sessions.

In considering whether to continue the Management Agreement, the Board reviewed materials provided by an independent data provider, which included, among other items, fee, expense and performance information compared to peer funds (the Peer Funds and, collectively with the Fund, the Peer Group) and performance comparisons to a larger category universe; summary information prepared by the Fund's investment manager (the Investment Manager); and a memorandum from counsel to the Independent Directors outlining the legal duties of the Board. The Board also spoke directly with a representative of the independent data provider and met with investment management personnel. In addition, the Board considered information provided from time to time by the Investment Manager throughout the year at meetings of the Board, including presentations by portfolio managers relating to the investment performance of the Fund and the investment strategies used in pursuing the Fund's objective. The Board also considered information provided by the Investment Manager in response to a request for information submitted by counsel to the Independent Directors, on behalf of the Independent Directors, as well as information provided by the Investment Manager in response to a supplemental request. In particular, the Board considered the following:

(i) The nature, extent and quality of services to be provided by the Investment Manager: The Board reviewed the services that the Investment Manager provides to the Fund, including, but not limited to, making the day-to-day investment decisions for the Fund, placing orders for the investment and reinvestment of the Fund's assets, furnishing information to the Board regarding the Fund's portfolio, providing individuals to serve as Fund officers, and generally managing the Fund's investments in accordance with the stated policies of the Fund. The Board also discussed with officers and portfolio managers of the Fund the types of transactions conducted on behalf of the Fund. Additionally, the Board took into account the services provided by the Investment Manager to its other funds and accounts, including those that have investment objectives and strategies similar to those of the Fund. The Board also considered the education, background and experience of the Investment Manager's personnel, particularly noting the potential benefit that the portfolio managers' work experience and favorable reputation can have on the Fund. The Board further noted the Investment Manager's ability to attract qualified and experienced personnel. The Board

34

Cohen & Steers Closed-End Opportunity Fund, Inc.

also considered the administrative services provided by the Investment Manager, including compliance and accounting services. After consideration of the above factors, among others, the Board concluded that the nature, extent and quality of services provided by the Investment Manager are satisfactory and appropriate.

(ii) Investment performance of the Fund and the Investment Manager: The Board considered the investment performance of the Fund compared to Peer Funds and compared to its benchmark. The Board considered that, on a net asset value basis (NAV), the Fund outperformed the Peer Group median for the one-, three- and five-year periods ended March 31, 2026, ranking 2 out of 6 peers, 2 out of 6 peers and 3 out of 6 peers, respectively, and underperformed the Peer Group median for the ten-year period ended March 31, 2026, ranking 5 out of 6 peers. The Board noted that, on a NAV basis, the Fund outperformed its linked benchmark for the one-, three-, five- and ten-year periods ended March 31, 2026. The Board considered that due to the unique nature of the Fund, it is difficult to make quantitative comparisons of the Fund's performance among the Peer Group. The Board engaged in discussions with the Investment Manager regarding the contributors to and detractors from the Fund's performance. The Board also considered additional supplemental information provided by the Investment Manager, including a narrative summary of various factors affecting performance and the Investment Manager's performance in managing similarly managed funds and accounts. The Board determined that Fund performance, in light of all considerations noted above, supported the continuation of the Management Agreement.

(iii) Cost of the services to be provided and profits to be realized by the Investment Manager from the relationship with the Fund: The Board considered the contractual and actual management fees paid by the Fund, as well as the Fund's total expense ratio. As part of its analysis, the Board considered the fee and expense analyses provided by the independent data provider. The Board noted that the Fund's actual management fee was lower than the Peer Group median, ranking 3 out of 6 peers. The Board also noted that the Fund's total expense ratio was the lowest in the Peer Group, ranking 1 out of 6 peers. The Board considered the effect the unitary fee charged by the Investment Manager, which limits total expenses of the Fund, has on the Fund's actual management fee and total expense ratio rankings. In light of the considerations above, the Board concluded that the Fund's current expense structure was satisfactory.

The Board also reviewed information regarding the profitability to the Investment Manager of its relationship with the Fund. The Board considered the level of the Investment Manager's profits and whether the profits were reasonable for the Investment Manager. The Board took into consideration other benefits to be derived by the Investment Manager in connection with the Management Agreement, noting particularly the research and related services, within the meaning of Section 28(e) of the Securities Exchange Act of 1934, which the Investment Manager receives by allocating the Fund's brokerage transactions. The Board further considered that the Investment Manager continues to reinvest profits back in the business, including upgrading and/or implementing new trading, compliance and accounting systems, and by adding investment personnel to the portfolio management teams. The Board concluded that the profits realized by the Investment Manager from its relationship with the Fund were reasonable and consistent with the Investment Manager's fiduciary duties.

(iv) The extent to which economies of scale would be realized as the Fund grows and whether fee levels would reflect such economies of scale: The Board considered that, as a closed-end fund, the

35

Cohen & Steers Closed-End Opportunity Fund, Inc.

Fund would not be expected to have inflows of capital that might produce increasing economies of scale. The Board determined that, given the Fund's closed-end structure, there were no significant economies of scale that were not already being shared with shareholders. In considering economies of scale, the Board also noted, as discussed above in (iii), that the Investment Manager continues to reinvest profits back in the business.

(v) Comparison of services to be rendered and fees to be paid to those under other investment management contracts, such as contracts of the same and other investment advisors or other clients: As discussed above in (iii), the Board compared the fees paid under the Management Agreement to those under other investment management contracts of other investment advisors managing Peer Funds. The Board also compared the services rendered and fees paid under the Management Agreement to fees paid, including the ranges of such fees, under the Investment Manager's other fund management agreements and advisory contracts with institutional and other clients with similar investment mandates, noting that the Investment Manager provides more services to the Fund than it does to institutional or subadvised accounts. The Board also considered the entrepreneurial risk and financial exposure assumed by the Investment Manager in developing and managing the Fund that the Investment Manager does not have with institutional and other clients and other differences in the management of registered investment companies and institutional accounts. The Board determined that on a comparative basis the fees under the Management Agreement were reasonable in relation to the services provided.

No single factor was cited as determinative to the decision of the Board, and each Director may have assigned different weights to the various factors. Rather, after weighing all of the considerations and conclusions discussed above, the Board, including the Independent Directors, unanimously approved the continuation of the Management Agreement.
