Bancroft Fund Ltd. Semiannual Report — March 31, 2025 |
| James A. Dinsmore, CFA BA, Cornell University MBA, Rutgers University

To Our Shareholders,

For the six months ended March 31, 2025, the Net Asset Value (NAV) total return of the Bancroft Fund Ltd. was 3.7% compared to the total return of 1.2% for the ICE Bank of America U.S. Convertibles Index. The total return for the Fund’s publicly traded shares was 7.6%. The Fund’s NAV per share was $19.30, while the price of the publicly traded shares closed at $17.42 on the NYSE American. See page 3 for additional performance information.

Enclosed are the financial statements, including the schedule of investments, as of March 31, 2025.

Investment Objective and Strategy (Unaudited)

The Fund is a closed-end, diversified management investment company and invests primarily in convertible securities, with the objectives of providing income and the potential for capital appreciation, which objectives the Fund considers to be relatively equal over the long term due to the nature of the securities in which it invests.

As permitted by regulations adopted by the Securities and Exchange Commission, paper copies of the Fund’s annual and semiannual shareholder reports will no longer be sent by mail, unless you specifically request paper copies of the reports. Instead, the reports will be made available on the Fund’s website (www.gabelli.com), and you will be notified by mail each time a report is posted and provided with a website link to access the report. If you already elected to receive shareholder reports electronically, you will not be affected by this change and you need not take any action. To elect to receive all future reports on paper free of charge, please contact your financial intermediary, or, if you invest directly with the Fund, you may call 800-422-3554 or send an email request to info@gabelli.com.

Performance Discussion (Unaudited)

For the six months ending March 31, 2025, Bancroft Fund’s NAV was up 3.68%, outperforming the ICE BAML All Convertibles Index which was up 1.17%.

Bancroft started the fiscal year with strong performance driven by two main factors. First, we saw a broad market rally following the election. Markets moved higher in anticipation of less regulation and lower taxes, and the fund’s relative sensitivity to underlying equities helped it outperform the convertible market. Second, the fund owns a few smaller issues that saw significant moves higher in the quarter due to improving credit expectations. As many of these positions had little or no weighting in the broader market index, their outperformance was notable. The fund also benefitted from improving market breadth, a similar trend that aided performance in the prior quarter. Top performers in the quarter included Microstrategy 2.25% of ‘32, Sofi 1.25% of ‘29 and Bloom Energy 3% of ‘28.

Convertibles performed relatively well in a volatile environment during the second fiscal quarter, outperforming the broader equity indices while significantly outperforming their underlying equities. As uncertainty increased around tariffs and the implications of a potential global trade war, the bond-like features helped limit downside relative to equities. Our top performers in the second quarter included Alibaba 0.5% of ‘31 and MP Materials 3% of ‘30.

Convertible issuance was quite strong in the first fiscal quarter, bringing total 2024 issuance to the third highest level in nearly 20 years. As uncertainty crept into markets in the second fiscal quarter, issuance slowed down from last year’s pace, but we still saw several notable large deals. We believe the market is well positioned for risk adjusted equity exposure and our focus remains on the total return portion of the convertible market which should have the most asymmetrical return profile over the next few years.

At current levels the convertible market offers a YTM of 4.1% and a 49% premium to conversion value. Our portfolio offers a 5.0% YTM at a 47% conversion premium. Sensitivity to moves in underlying equities moved lower and the market delta is now 50. Bancroft’s portfolio is slightly more equity sensitive with a delta of 54. At quarter end our portfolio was 13% equity sensitive, 68% total return, and 19% fixed income equivalent. This compares to the market at 33% equity, 32% total return, and 35% fixed income equivalent.

We have managed convertibles through multiple market cycles and remain optimistic for the possibilities of the asset class this year. Our focus on the total return segment of the market allows us to position the portfolio cautiously while participating when the market moves higher. We continue to look for opportunities for equity upside, particularly when market volatility creates attractive entry points. We believe this balanced approach will provide the best opportunity for long-term asymmetrical returns.

Thank you for your investment in the Bancroft Fund.

We appreciate your confidence and trust.

| (b) | Performance returns for periods of less than one year are not annualized. Returns represent past performance and do not guarantee future results. Investment returns and the principal value of an investment will fluctuate. The Fund’s use of leverage may magnify the volatility of net asset value changes versus funds that do not employ leverage. When shares are sold, they may be worth more or less than their original cost. Current performance may be lower or higher than the performance data presented. Visit www.gabelli.com for performance information as of the most recent month end.

Bancroft Fund Ltd.
Notes to Financial Statements (Unaudited)

1. Organization. Bancroft Fund Ltd. (the Fund) was organized in April 1971 as a Delaware statutory trust. The Fund is a diversified closed-end management investment company registered under the Investment Company Act of 1940, as amended (the 1940 Act). The Fund commenced investment operations in April 1971. On February 15, 2023, the Board of Directors (the Board) approved a change on the Fund’s fiscal year end from October 31 to September 30, effective as of September 30, 2023.

The Fund’s primary investment objective is to provide income and the potential for capital appreciation, which objectives the Fund considers to be relatively equal over the long term due to the nature of the securities in which it invests. The Fund invests primarily in convertible and equity securities.

Gabelli Funds, LLC (the Adviser), with its principal offices located at One Corporate Center, Rye, New York 10580-1422, serves as investment adviser to the Fund. The Adviser makes investment decisions for the Fund and continuously reviews and administers the Funds’ investment program and manages the operations of the Fund under the general supervision of the Fund’s Board.

2. Significant Accounting Policies. As an investment company, the Fund follows the investment company accounting and reporting guidance, which is part of U.S. generally accepted accounting principles (GAAP) that may require the use of management estimates and assumptions in the preparation of its financial statements. The Board has designated the Adviser as the valuation designee under Rule 2a-5. Actual results could differ from those estimates. The following is a summary of significant accounting policies followed by the Fund in the preparation of its financial statements.

Security Valuation. Portfolio securities listed or traded on a nationally recognized securities exchange or traded in the U.S. over-the-counter market for which market quotations are readily available are valued at the last quoted sale price or a market’s official closing price as of the close of business on the day the securities are being valued. If there were no sales that day, the security is valued at the average of the closing bid and asked prices or, if there were no asked prices quoted on that day, then the security is valued at the closing bid price on that day. If no bid or asked prices are quoted on such day, the security is valued at the most recently available price or, if the Board so determines, by such other method as the Board shall determine in good faith to reflect its fair market value. Portfolio securities traded on more than one national securities exchange or market are valued according to the broadest and most representative market, as determined by the Adviser.

Portfolio securities primarily traded on a foreign market are generally valued at the preceding closing values of such securities on the relevant market, but may be fair valued pursuant to procedures established by the Board if market conditions change significantly after the close of the foreign market, but prior to the close of business on the day the securities are being valued. Debt obligations for which market quotations are readily available are valued at the average of the latest bid and asked prices. If there were no asked prices quoted on such day, the securities are valued using the closing bid price, unless the Board determines such amount does not reflect the security’s fair value, in which case these securities will be fair valued as determined by the Board. Certain securities are valued principally using dealer quotations. Futures contracts are valued at the closing settlement price of the exchange or board of trade on which the applicable contract is traded. OTC futures and options on futures for which market quotations are readily available will be valued by quotations received from a pricing service or, if no quotations are available from a pricing service, by quotations obtained from one or more dealers in the instrument in question by the Adviser.

12

Bancroft Fund Ltd.
Notes to Financial Statements (Unaudited) (Continued)

Securities and assets for which market quotations are not readily available are fair valued as determined by the Board. Fair valuation methodologies and procedures may include, but are not limited to: analysis and review of available financial and non-financial information about the company; comparisons with the valuation and changes in valuation of similar securities, including a comparison of foreign securities with the equivalent U.S. dollar value American Depositary Receipt securities at the close of the U.S. exchange; and evaluation of any other information that could be indicative of the value of the security.

The inputs and valuation techniques used to measure fair value of the Fund’s investments are summarized into three levels as described in the hierarchy below:

| ● | Level 1 — unadjusted quoted prices in active markets for identical securities;

| ● | Level 2 — other significant observable inputs (including quoted prices for similar securities, interest rates, prepayment speeds, credit risk, etc.); and

| ● | Level 3 — significant unobservable inputs (including the Board’s determinations as to the fair value of investments).

A financial instrument’s level within the fair value hierarchy is based on the lowest level of any input both individually and in the aggregate that is significant to the fair value measurement. The inputs or methodology used for valuing securities are not necessarily an indication of the risk associated with investing in those securities. The summary of the Fund’s investments in securities by inputs used to value the Fund’s investments as of March 31, 2025 is as follows:

|  | Valuation Inputs |  |
|  | Level 1 Quoted Prices |  | Level 2 Other Significant Observable Inputs |  | Level 3 Significant Unobservable Inputs (a) |  | Total Market Value at 03/31/25

| (a) | The inputs for these securities are not readily available and are derived based on the judgment of the Adviser according to procedures approved by the Board.

| (b) | Please refer to the Schedule of Investments for the industry classifications of these portfolio holdings.

General. The Fund uses recognized industry pricing services – approved by the Board and unaffiliated with the Adviser – to value most of its securities, and uses broker quotes provided by market makers of securities not valued by these and other recognized pricing sources. Several different pricing feeds are received to value domestic equity securities, international equity securities, preferred equity securities, and fixed income securities. The data within these feeds are ultimately sourced from major stock exchanges and trading systems where these securities trade. The prices supplied by external sources are checked by obtaining quotations or actual transaction prices from market participants. If a price obtained from the pricing source is deemed

13

Bancroft Fund Ltd.
Notes to Financial Statements (Unaudited) (Continued)

unreliable, prices will be sought from another pricing service or from a broker/dealer that trades that security or similar securities.

Fair Valuation. Fair valued securities may be common or preferred equities, warrants, options, rights, or fixed income obligations. Where appropriate, Level 3 securities are those for which market quotations are not available, such as securities not traded for several days, or for which current bids are not available, or which are restricted as to transfer. When fair valuing a security, factors to consider include recent prices of comparable securities that are publicly traded, reliable prices of securities not publicly traded, the use of valuation models, current analyst reports, valuing the income or cash flow of the issuer, or cost if the preceding factors do not apply. A significant change in the unobservable inputs could result in a lower or higher value in Level 3 securities. The circumstances of Level 3 securities are frequently monitored to determine if fair valuation measures continue to apply.

The Adviser reports quarterly to the Board the results of the application of fair valuation policies and procedures. These may include backtesting the prices realized in subsequent trades of these fair valued securities to fair values previously recognized.

Investments in other Investment Companies. The Fund may invest, from time to time, in shares of other investment companies (or entities that would be considered investment companies but are excluded from the definition pursuant to certain exceptions under the 1940 Act) (the Acquired Funds) in accordance with the 1940 Act and related rules. Shareholders in the Fund would bear the pro rata portion of the periodic expenses of the Acquired Funds in addition to the Fund’s expenses. During the six months ended March 31, 2025, the Fund did not incur periodic expenses charged by Acquired Funds.

Foreign Currency Translations. The books and records of the Fund are maintained in U.S. dollars. Foreign currencies, investments, and other assets and liabilities are translated into U.S. dollars at current exchange rates. Purchases and sales of investment securities, income, and expenses are translated at the exchange rate prevailing on the respective dates of such transactions. Unrealized gains and losses that result from changes in foreign exchange rates and/or changes in market prices of securities have been included in unrealized appreciation/depreciation on investments and foreign currency translations. Net realized foreign currency gains and losses resulting from changes in exchange rates include foreign currency gains and losses between trade date and settlement date on investment securities transactions, foreign currency transactions, and the difference between the amounts of interest and dividends recorded on the books of the Fund and the amounts actually received. The portion of foreign currency gains and losses related to fluctuation in exchange rates between the initial purchase trade date and subsequent sale trade date is included in realized gain/(loss) on investments.

Foreign Securities. The Fund may directly purchase securities of foreign issuers. Investing in securities of foreign issuers involves special risks not typically associated with investing in securities of U.S. issuers. The risks include possible revaluation of currencies, the inability to repatriate funds, less complete financial information about companies, and possible future adverse political and economic developments. 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.

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

14

Bancroft Fund Ltd.
Notes to Financial Statements (Unaudited) (Continued)

Restricted Securities. The Fund may invest up to 20% of its net assets in securities for which the markets are restricted. Restricted securities include securities whose disposition is subject to substantial legal or contractual restrictions. The sale of restricted securities often requires more time and results in higher brokerage charges or dealer discounts and other selling expenses than the sale of securities eligible for trading on national securities exchanges or in the over-the-counter markets. Restricted securities may sell at a price lower than similar securities that are not subject to restrictions on resale. Securities freely saleable among qualified institutional investors under special rules adopted by the SEC may be treated as liquid if they satisfy liquidity standards established by the Board. The continued liquidity of such securities is not as well assured as that of publicly traded securities, and accordingly the Board will monitor their liquidity. At March 31, 2025, the Fund did not hold any restricted securities.

Securities Transactions and Investment Income. Securities transactions are accounted for on the trade date with realized gain/(loss) on investments determined by using the identified cost method. Interest income (including amortization of premium and accretion of discount) is recorded on an accrual basis. Premiums and discounts on debt securities are amortized using the effective yield to maturity method or amortized to earliest call date, if applicable. Dividend income is recorded on the ex-dividend date, except for certain dividends from foreign securities that are recorded as soon after the ex-dividend date as the Fund becomes aware of such dividends.

Custodian Fee Credits. When cash balances are maintained in the custody account, the Fund receives credits which are used to offset custodian fess. The gross expenses paid under the custody arrangement are included in custodian fees in the Statement of Operations with the corresponding expense offset, if any, shown as “Custodian fee credits.”

Distributions to Shareholders. Distributions to common shareholders are recorded on the ex-dividend date. The characterization of distributions to shareholders are based on income and capital gains as determined in accordance with federal income tax regulations, which may differ from income and capital gains as determined under GAAP. These differences are primarily due to differing treatments of income and gains on various investment securities and foreign currency transactions held by the Fund, timing differences, and differing characterizations of distributions made by the Fund. Distributions from net investment income for federal income tax purposes include net realized gains on foreign currency transactions. These book/tax differences are either temporary or permanent in nature. To the extent these differences are permanent, adjustments are made to the appropriate capital accounts in the period when the differences arise. These reclassifications have no impact on the NAV of the Fund.

Under the Fund’s current common share distribution policy, the Fund declares and pays quarterly distributions from net investment income, capital gains, and paid-in capital. The actual source of the distribution is determined after the end of the year. Pursuant to this policy, distributions during the year may be made in excess of required distributions. To the extent such distributions are made from current earnings and profits, they are considered ordinary income or long term capital gains. Distributions sourced from paid-in capital should not be considered as dividend yield or the total return from an investment in the Fund. The Board will continue to monitor the Fund’s distribution level, taking into consideration the Fund’s NAV and the financial market environment. The Fund’s distribution policy is subject to modification by the Board at any time.

Distributions to 5.375% Series A Cumulative Preferred Shares (Series A Preferred) are recorded on a daily basis and are determined as described in Note 6.

Bancroft Fund Ltd.
Notes to Financial Statements (Unaudited) (Continued)

The tax character of distributions paid during the fiscal year ended September 30, 2024 was as follows:

|  | Common |  | Preferred
Distributions paid from: |  |  |  |  |  |  |  |
Ordinary income |  | $ | 6,578,449 |  |  | $ | 1,427,027 |
Net long term capital gains |  |  | 804,632 |  |  |  | 174,544 |
Return of capital |  |  | 90,284 |  |  |  | – |
Total distributions paid |  | $ | 7,473,365 |  |  | $ | 1,601,571 |

Provision for Income Taxes. The Fund intends to continue to qualify as a regulated investment company under Subchapter M of the Internal Revenue Code of 1986, as amended (the Code). It is the policy of the Fund to comply with the requirements of the Code applicable to regulated investment companies and to distribute substantially all of its net investment company taxable income and net capital gains. Therefore, no provision for federal income taxes is required.

The following summarizes the tax cost of investments and the related net unrealized depreciation at March 31, 2025:

|  | Cost |  | Gross Unrealized Appreciation |  | Gross Unrealized Depreciation |  | Net Unrealized Depreciation
Investments |  | $145,222,884 |  | $8,320,885 |  | $(12,349,367) |  | $(4,028,482)

The Fund is required to evaluate tax positions taken or expected to be taken in the course of preparing the Fund’s tax returns to determine whether the tax positions are “more-likely-than-not” of being sustained by the applicable tax authority. Income tax and related interest and penalties would be recognized by the Fund as tax expense in the Statement of Operations if the tax positions were deemed not to meet the more-likely-than-not threshold. During the six months ended March 31, 2025, the Fund did not incur any income tax, interest, or penalties. As of March 31, 2025, the Adviser has reviewed all open tax years and concluded that there was no impact to the Fund’s net assets or results of operations. The Fund’s federal and state tax returns for the prior three fiscal years remain open, subject to examination. On an ongoing basis, the Adviser will monitor the Fund’s tax positions to determine if adjustments to this conclusion are necessary.

3. Investment Advisory Agreement and Other Transactions. The Fund has entered into an investment advisory agreement (the Advisory Agreement) with the Adviser which provides that the Fund will pay the Adviser a fee, computed weekly and paid monthly, equal on an annual basis to 0.80% of the first $100,000,000 of the Fund’s average weekly net assets including the liquidation value of preferred shares and 0.55% of the Fund’s average weekly net assets including the liquidation value of preferred shares in excess of $100,000,000. In accordance with the Advisory Agreement, the Adviser provides a continuous investment program for the Fund’s portfolio and oversees the administration of all aspects of the Fund’s business and affairs.

4. Portfolio Securities. Purchases and sales of securities during the six months ended March 31, 2025, other than short term securities and U.S. Government obligations, aggregated $69,316,422 and $70,513,773, respectively.

The cost of calculating the Fund’s NAV per share is a Fund expense pursuant to the Advisory Agreement between the Fund and the Adviser. Under the sub-administration agreement with Bank of New York Mellon, the fees paid include the cost of calculating the Fund’s NAV. The Fund reimburses the Adviser for this service. During the six months ended March 31, 2025, the Fund accrued $22,500 in accounting fees in the Statement of Operations.

As per the approval of the Board, the Fund compensates officers of the Fund, who are employed by the Fund and are not employed by the Adviser (although the officers may receive incentive based variable compensation from affiliates of the Adviser). During the six months ended March 31, 2025, the Fund accrued $39,340 in payroll expenses in the Statement of Operations.

The Fund pays each Independent Trustee and certain Interested Trustees retainers and per meeting fees, plus specified amounts to the Lead Trustee and Audit Committee Chairman. Trustees are also reimbursed for out of pocket expenses incurred in attending meetings. Trustees who are directors or employees of the Adviser or an affiliated company receive no compensation or expense reimbursement from the Fund.

6. Capital. The Fund is authorized to issue an unlimited number of common shares of beneficial interest (par value $0.01). The Board has authorized the repurchase of its common shares on the open market when the shares are trading at a discount of 10% or more (or such other percentage as the Board may determine from time to time) from the NAV of the shares. During the six months ended March 31, 2025 and the fiscal year ended September 30, 2024, the Fund repurchased and retired 15,794 and 56,316, of its common shares at investments of $287,711 and $871,390, respectively, and at average discounts of approximately 12.45% and 15.67% from its NAV.

Transactions in common shares of beneficial interest for the six months ended March 31, 2025 and the fiscal year ended September 30, 2024 were as follows:

|  | Six Months Ended March 31, 2025 (Unaudited) |  | Year Ended September 30, 2024
|  | Shares |  | Amount |  | Shares |  | Amount
Net increase in net assets from common shares issued upon reinvestment of distributions |  |  | 48,929 |  |  | $ | 891,473 |  |  |  | 57,210 |  |  | $ | 920,505 |
Net decrease from repurchase of common shares |  |  | (15,794 | ) |  |  | (287,711 | ) |  |  | (56,316 | ) |  |  | (871,390 | )
Net increase from transactions in Fund shares |  |  | 33,135 |  |  | $ | 603,762 |  |  |  | 894 |  |  | $ | 49,115 |

As of March 31, 2025, the Fund had an effective shelf registration, available through May 27, 2027, which authorizes the issuance of $100 million in common or preferred shares.

On August 9, 2016, the Fund issued 1,200,000 shares of 5.375% Series A Cumulative Preferred (Series A Preferred). Commencing on August 9, 2021, the Fund, at its option, may redeem its Series A Preferred in whole or in part at the redemption price plus an amount equal to the accumulated and unpaid dividends whether or not declared on such shares. In addition, the Board has authorized the repurchase of Series A Preferred Shares in the open market at prices less than the $25 liquidation value per share. During the six months ended March 31, 2025 and the fiscal year ended September 30, 2024, the Fund repurchased and retired 30,114 and 19,150

17

Bancroft Fund Ltd.
Notes to Financial Statements (Unaudited) (Continued)

Series A Preferred at investments of $703,489 and $435,078 and at average discounts of approximately 9.12% and 6.64% to the liquidation preference. At March 31, 2025, 1,147,149 Series A Preferred were outstanding and accrued dividends amounted to $23,049.

The Fund’s Declaration of Trust, as amended, authorizes the issuance of an unlimited number of Series A Preferred, par value $0.01. The Preferred Shares are senior to the common shares and result in the financial leveraging of the common shares. Such leveraging tends to magnify both the risks and opportunities to common shareholders. Dividends on the Series A Preferred are cumulative. The Fund is required by the 1940 Act and by the Fund’s Statement of Preferences to meet certain asset coverage tests with respect to the Preferred Shares. If the Fund fails to meet these requirements and does not correct such failure, the Fund may be required to redeem, in part or in full, the Preferred Shares at the redemption price of $25 per share plus an amount equal to the accumulated and unpaid dividends whether or not declared on such shares in order to meet these requirements. Additionally, failure to meet the foregoing asset coverage requirements could restrict the Fund’s ability to pay dividends to common shareholders and could lead to sales of portfolio securities at inopportune times. The income received on the Fund’s assets may vary in a manner unrelated to the fixed rates, which could have either a beneficial or detrimental impact on net investment income and gains available to common shareholders.

The holders of preferred shares generally are entitled to one vote per share held on each matter submitted to a vote of shareholders of the Fund and will vote together with holders of common shares as a single class. The holders of Series A Preferred voting together as a single class also have the right currently to elect two Trustees and, under certain circumstances, are entitled to elect a majority of the Board of Trustees. In addition, the affirmative vote of a majority of the votes entitled to be cast by holders of all outstanding shares of the preferred shares, voting as a single class, will be required to approve any plan of reorganization adversely affecting the preferred stock, and the approval of two-thirds of each class, voting separately, of the Fund’s outstanding voting stock must approve the conversion of the Fund from a closed-end to an open-end investment company. The approval of a majority (as defined in the 1940 Act) of the outstanding preferred shares and a majority (as defined in the 1940 Act) of the Fund’s outstanding voting securities are required to approve certain other actions, including changes in the Fund’s investment objectives or fundamental investment policies.

7. Convertible Securities Concentration. It is the Fund’s policy to invest at least 65% of its assets in convertible securities. Although convertible securities do derive part of their value from that of the securities into which they are convertible, they are not considered derivative financial instruments. However, the Fund’s mandatory convertible securities include features which render them more sensitive to price changes of their underlying securities. Thus they expose the Fund to greater downside risk than traditional convertible securities, but generally less than that of the underlying common stock.

8. Indemnifications. The Fund enters into contracts that contain a variety of indemnifications. The Fund’s maximum exposure under these arrangements is unknown. However, the Fund has not had prior claims or losses pursuant to these contracts. Management has reviewed the Fund’s existing contracts and expects the risk of loss to be remote.

9. Segment Reporting. In this reporting period, the Fund adopted FASB Accounting Standards Update 2023-07, Segment Reporting (Topic 280) - Improvements to Reportable Segment Disclosures (ASU 2023-07). Adoption of the new standard impacted financial statement disclosures only and did not affect the Fund’s financial position or results of operations. The Fund’s Principal Executive Officer and Principal Financial Officer

18

Notes to Financial Statements (Unaudited) (Continued)

act as the Fund’s chief operating decision maker (CODM), as defined in Topic 280, assessing performance and making decisions about resource allocation. The CODM has determined that the Fund has a single operating segment based on the fact that the CODM monitors the operating results of the Fund as a whole and the Fund’s long-term strategic asset allocation is guided by the Fund’s investment objective and principal investment strategies, and executed by the Fund’s portfolio management team, comprised of investment professionals employed by the Adviser. The financial information provided to and reviewed by the CODM is consistent with that presented in the Fund’s Schedule of Investments, Statements of Operations and Changes in Net Assets and Financial Highlights.

10. Subsequent Events. Management has evaluated the impact on the Fund of all subsequent events occurring through the date the financial statements were issued and has determined that there were no other subsequent events requiring recognition or disclosure in the financial statements.

Certifications

The Fund’s Chief Executive Officer has certified to the New York Stock Exchange (NYSE) that, as of May 20, 2025, he was not aware of any violation by the Fund of applicable NYSE corporate governance listing standards. The Fund reports to the SEC on Form N-CSR which contains certifications by the Fund’s principal executive officer and principal financial officer that relate to the Fund’s disclosure in such reports and that are required by Rule 30a-2(a) under the 1940 Act.

Shareholder Meeting – May 12, 2025 – Final Results

The Fund’s Annual Meeting of Shareholders was held on May 12, 2025. At that meeting common and preferred shareholders, voting together as a single class, re-elected Elizabeth C. Bogan, Agnes Mullady, Jane D. O’Keeffe, and Anthonie C. van Ekris as Trustees of the Fund, with 4,314,718 votes, 4,328,867 votes, 4,332,654 votes, and 4,308,652 votes cast in favor of these Trustees, and 404,590 votes, 390,441 votes, 386,654 votes, and 410,656 votes withheld for these Trustees, respectively.

Mario J. Gabelli, Kinchen C. Bizzell, James P. Conn, Frank J. Fahrenkopf, Daniel D. Harding, Michael J. Melarkey, Christina A. Peeney, and Nicolas W. Platt continue to serve in their capacities as Trustees of the Fund.

Item 11. Statement Regarding Basis for Approval of Investment Advisory Contract.

At its meeting on February 13, 2024, the Board of Trustees (Board) of the Fund approved the continuation of the investment advisory agreement with the Adviser for the Fund on the basis of the recommendation by the trustees who are not interested persons of the Fund (the Independent Board Members). The following paragraphs summarize the material information and factors considered by the Independent Board Members as well as their conclusions relative to such factors.

Nature, Extent, and Quality of Services. The Independent Board Members considered information regarding the portfolio managers, the depth of the analyst pool available to the Adviser and the portfolio managers, the scope of supervisory, administrative, shareholder, and other services supervised or provided by the Adviser, and the absence of significant service problems reported to the Board. The Independent Board Members noted the experience, length of service, and reputation of the portfolio managers as well as the Independent Board Members’ satisfaction with the performance of the portfolio managers since the Adviser assumed control of the Fund in 2015.

Investment Performance. The Independent Board Members reviewed the performance of the Fund for the one-, three-, five-, and ten-year periods (as of December 31, 2024) against a peer group of eighteen other convertible funds prepared by the Adviser (the “Adviser Peer Group”). The Independent Board Members noted that the Fund’s performance was in the first quartile for the one-year period, the fourth quartile for the three-, and five-year periods and the third quartile for the ten-year period for the Adviser Peer Group. The Independent Board Members noted the Fund’s strong performance during the past year. The Independent Board Members then discussed the utility of these comparisons, noting the inclusion of unlevered open-end funds in the applicable peer groups and the impact of the Fund’s leveraged capital structure. The Independent Board Members noted that the Fund’s longer term performance compared more favorably to leveraged closed-end funds included in the Adviser Peer Group. The Independent Board Members discussed how this result was consistent with their overall view of the high quality portfolio management services the Adviser provides to the Fund.

Profitability. The Independent Board Members reviewed summary data regarding the profitability of the Fund to the Adviser both with an administrative overhead charge and without such charge, and noted the Adviser’s estimated pre-tax operating margin attributable to the Fund in both scenarios.

Economies of Scale. The Independent Board Members considered the major elements of the Adviser’s cost structure and the relationship of those elements to potential economies of scale. The Independent Board Members noted that the Fund was a closed-end fund and unlikely to realize any economies of scale potentially available through growth in the absence of additional offerings.

Sharing of Economies of Scale. The Independent Board Members noted that the Fund’s advisory fee contained a reduction for assets in excess of $100 million, which would indicate a sharing even if economies of scale were not experienced at such a low asset level.

Service and Cost Comparisons. The Independent Board Members compared the expense ratios of the investment management fee, other expenses, and total expenses of the Fund with similar expense ratios of the Adviser Peer Group and the Lipper Peer Group. The Independent Board Members noted that the Adviser’s management fee includes substantially all administrative services for the Fund as well as investment advisory services. The Independent Board Members noted that the Fund’s investment management fee was below the Adviser Peer Group average and total expense ratio was above the Adviser Peer Group average. The Independent Board Members also noted that the management fee structure was different from that in effect for most of the Gabelli funds, in that it contains a reduction for assets in excess of $100 million and is lower than the management fees in effect for most other Gabelli funds due to the retention of the Fund’s historical fee structure when the Adviser assumed the management of the Fund in 2015.

Conclusions. The Independent Board Members concluded that the Fund enjoyed highly experienced portfolio management services and good ancillary services, and that the Fund’s performance record has been acceptable since the Adviser assumed control of the Fund in 2015. The Independent Board Members concluded that the profitability to the Adviser of managing the Fund was acceptable and that economies of scale were not a significant factor in their thinking at this point. The Independent Board Members did not view the potential profitability of ancillary services as material to their decision. On the basis of the foregoing and without assigning particular weight to any single conclusion, the Independent Board Members determined to recommend continuation of the Advisory Agreement to the full Board.

Based on a consideration of all these factors in their totality, the Board Members, including all of the Independent Board Members, determined that the Fund’s advisory fee was appropriate in light of the quality of services provided and in light of the other factors described above that the Board deemed relevant. Accordingly, the Board Members determined to approve the continuation of the Fund’s Advisory Agreement. The Board Members based their decision on evaluations of all these factors as a whole and did not consider any one factor as all important or controlling.
