Performance Discussion (Unaudited)

For the fiscal year ended September 30, 2025, the Gabelli Convertible and Income Securities Fund’s NAV was up 31.0%, while the ICE BofA U.S. Convertibles Index was up 19.6%.

The first fiscal quarter was highlighted by 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 outperform the convertible market. Convertible issuance picked up substantially in the quarter, and we were able to position the fund with a focus on balanced convertibles while maintaining a higher delta relative to the market. This set up the fund favorably for the year.

Volatility increased throughout the fiscal second quarter as uncertainty over tariffs and the impacts of trade wars weighed on global markets. Convertibles acted well in this volatile environment, outperforming the broader equity indices while significantly outperforming their underlying equities. Convertible issuance slowed, but we still saw some notable large deals. Our positioning helped the fund outperform during the quarter.

The third fiscal quarter began with a significant increase in volatility after the Trump administration laid out its plans for tariffs which were higher and broader than the market had been anticipating. Markets moved lower as they digested this new information concerning a global trade war with the potential for drastic changes to supply chains and margin assumptions. Convertibles were not immune from this decline, but their bond features helped to buoy them relative to the broader equity markets as well as their underlying equities, making them a top performing asset class in the quarter. As the administration walked back some of their initial rhetoric, markets began to recover, and we ended the quarter with a substantial market rally off the lows. With this rally, the fund benefited from strong moves in its underlying equities and outperformed the market.

Convertibles were again a top performing asset class in the fourth fiscal quarter driven by strong underlying equity performance. Markets looked past geopolitical risk, tariffs, and some mixed economic data to march higher, benefiting the convertible market broadly. At the end of the quarter, we got our first interest rate cut of the year, and we expect more to follow. This should be a tailwind for our market in the form of increasing bond floors and earnings multiple expansions. We believe convertibles offer a great opportunity to maintain risk adjusted equity exposure in this environment.

Convertible issuance was quite strong this year, at a pace we haven’t seen since the peak years of 2020 and 2021. Some of this issuance has come at attractive terms, while some pricing has been driven by convertible arbitrage investors, leading to lower yields and higher premiums than we have seen in some time. This has increased the total market to $388 billion, broadened the pool of convertibles available to us and been beneficial to performance in the near term. Given the mix of less attractive pricing, it is possible that some of this issuance could prove to be a drag on the broader convertible market over the coming years. We participate in new issuance where appropriate but continue to build our portfolio around convertibles that we believe have asymmetrical upside potential.

At current levels, the convertible market offers a Yield to Maturity (YTM) of 2.7% and a 31% premium to conversion value. Our portfolio offers a 2.7% YTM at a 30% conversion premium. Sensitivity to moves in underlying equities increased throughout the year with the market delta now at 62. GCV’s portfolio is now in line with the market at 62. At fiscal year-end our portfolio was 19% equity sensitive, 65% total return, and 16% fixed income equivalent. This compares to the market at 44% equity, 36% total return, and 20% fixed income equivalent, highlighting our relative focus on balanced profile convertibles.

We have managed convertibles through multiple market cycles. Their asymmetrical return profile allows us to participate as underlying equities move higher, which has greatly benefited GCV shareholders this fiscal

2

year. As our market expands, we continue to seek out convertibles with attractive return profiles that allow for risk adjusted equity exposure in names where we have conviction. We typically find these names in the total return segment of the market, where we continue to have the largest percentage of our holdings. The equivalent equity portion of the portfolio has some company specific attributes that we believe can lead to an asymmetrical return profile as well. This strategy helped the Fund outperform the ICE BofA U.S. Convertibles Index by a substantial margin this fiscal year.

Our top contributors to performance for the fiscal year were Bloom Energy 3% of ’28 (no longer held), MP Materials Corp. 3% of ’30 (0.5% of total investments as of September 30, 2025), Lumentum Holdings Inc. 1.5% of ’29 (1.5%) and Pagaya 6.125% of ’29 (no longer held). Our top detractors were Sunnova 2.625% of ’28 (no longer held) and Sarepta 1.25% of ’27 (no longer held).

Notes to Financial Statements

1. Organization. The Gabelli Convertible and Income Securities Fund (the Fund) was incorporated on December 19, 1988 in Maryland. The Fund is a diversified closed-end management investment company registered under the Investment Company Act of 1940, as amended (the 1940 Act). The investment objective is to seek a high level of total return through a combination of current income and capital appreciation by investing in convertible securities. The Fund commenced investment operations on July 3, 1989. At a special meeting of stockholders held on February 17, 1995, the Board of Directors (the Board) voted to approve the conversion of the Fund to closed-end status, effective March 31, 1995. On February 15, 2023, the Board approved a change of the fiscal year end of the Fund from December 31 to September 30, effective as of September 30, 2023. This report reflects the activity of the Fund for the fiscal year ended September 30, 2025.

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. 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. The Board has designated the Adviser as the valuation designee (Valuation Designee) under Rule 2a-5. 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 Valuation Designee so determines, by such other method as the Valuation Designee 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 Valuation Designee 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 Valuation Designee determines such amount does not reflect the securities’ fair value, in which case these securities will be fair valued as determined by the Valuation Designee. 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.

Notes to Financial Statements (Continued)

Securities and assets for which market quotations are not readily available are fair valued as determined by the Valuation Designee. 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 and other financial instruments by inputs used to value the Fund’s investments as of September 30, 2025 is as follows:

|  | Valuation Inputs |  |  |  |
|  | Level 1 Quoted Prices |  |  | Level 2 Other Significant Observable Inputs |  |  | Total Market Value at 09/30/25 |

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 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.

Series G and Series H Cumulative Preferred Stock. For financial reporting purposes only, the liquidation value of preferred stock that has a mandatory call date is classified as a liability within the Statement of Assets and Liabilities and the dividends paid on this preferred stock are included as a component of “Interest expense on preferred stock” within the Statement of Operations. Offering costs are amortized over the life of the preferred stock.

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.

Restricted Securities. The Fund may invest up to 15% 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 September 30, 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 fees. 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 Stockholders. Distributions to common stockholders are recorded on the ex-dividend date. Distributions to stockholders 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. Permanent differences were primarily due to market premium realized at disposition. These reclassifications have no impact on the NAV of the Fund.

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. 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 stockholders of the Fund’s 5.20% Series G Cumulative Preferred Stock and 5.20% Series H Cumulative Preferred Stock (Series G Preferred and Series H Preferred) are recorded on a daily basis and are determined as described in Note 6.

Notes to Financial Statements (Continued)

The tax character of distributions paid during the fiscal years ended September 30, 2025 and 2024 was as follows:

|  | Year Ended September 30, 2025 |  |  | Year Ended September 30, 2024 |
|  | Common |  |  | Common |
Distributions paid from: |  |  |  |  |  |  |  |
Ordinary income (inclusive of short term capital gains) |  | $ | 9,421,315 |  |  | $ | 912,260 |
Return of capital |  |  | 112,471 |  |  |  | 8,423,259 |
Total distributions paid |  | $ | 9,533,786 |  |  | $ | 9,335,519 |

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.

At September 30, 2025, the components of accumulated earnings/losses on a tax basis were as follows:

Net unrealized appreciation on investments and foreign currency translations |  | $ | 8,757,022 |
Other temporary differences* |  |  | (4,385 | )
Qualified late year loss deferrals |  |  | (1,583,693 | )
Total |  | $ | 7,168,944 |

| * | Other temporary differences are due to preferred share class distributions payable.

At September 30, 2025, the temporary differences between book basis and tax basis net unrealized appreciation on investments were primarily due to losses from wash sales for tax purposes, bond conversion premium adjustments and deemed dividends on convertible debt.

The following summarizes the tax cost of investments and the related net unrealized appreciation at September 30, 2025:

|  | Cost |  |  | Gross Unrealized Appreciation |  |  | Gross Unrealized Depreciation |  |  | Net Unrealized Appreciation |
Investments |  | $ | 84,066,315 |  |  | $ | 11,081,662 |  |  | $ | (2,324,640 | ) |  | $ | 8,757,022 |

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 fiscal year ended September 30, 2025, the Fund did not incur any income tax, interest, or penalties. As of September 30, 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.

ASU 2023-09 is effective for fiscal years beginning after December 15, 2024; early adoption is permitted. Management is currently evaluating the amendment and its impact to the financial statements and does not expect the guidance to have a material impact to the funds.

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 daily and paid monthly, equal on an annual basis to 1.00% of the value of its average daily net assets including the liquidation value of preferred stock. 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 fiscal year ended September 30, 2025, other than short term securities and U.S. Government obligations, aggregated $72,012,803 and $77,780,508, respectively. There were no purchases or sales of long term U.S. Government Obligations.

5. Transactions with Affiliates and Other Arrangements. During the fiscal year ended September 30, 2025, the Fund received credits from a designated broker who agreed to pay certain Fund operating expenses. The amount of such expenses paid through this directed brokerage arrangement during this period was $2,630.

The cost of calculating the Fund’s NAV per share is a Fund expense pursuant to the Advisory Agreement. Under the sub-administration agreement with Bank of New York, the fees paid include the cost of calculating the Fund’s NAV. The Fund reimburses the Adviser for this service. During the fiscal year ended September 30, 2025, the Fund accrued $45,000 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 fiscal year ended September 30, 2025, the Fund accrued $103,860 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. Line of Credit. The Fund participates in an unsecured and uncommitted line of credit of up to $10,000,000 under which it may borrow from the bank for temporary borrowing purposes. Borrowings under this arrangement bear interest at a floating rate based on equal to the higher of the Federal Funds Effective Rate or one-month Secured Overnight Financing Rate (SOFR) in effect on that day. This amount, if any, would be included in “Interest expense” in the Statement of Operations. During the year ended September 30, 2025, there were no borrowings under the line of credit.

7. Capital. The charter permits the Fund to issue 998,000,000 shares of common stock (par value $0.001). The Board has authorized the repurchase of up to 500,000 shares of common stock 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 fiscal years ended September 30, 2025 and 2024, the Fund did not repurchase any shares of its common stock in the open market.

For the fiscal years ended September 30, 2025 and 2024, transactions in common stock were as follows:

|  | Year Ended |  |  | Year Ended |
|  | September 30, 2025 |  |  | September 30, 2024 |
|  | Shares |  |  | Amount |  |  | Shares |  |  | Amount |
Net increase in net assets from common shares issued upon reinvestment of distributions |  |  | 330,172 |  |  | $ | 1,248,918 |  |  |  | 326,306 |  |  | $ | 1,199,913 |

As of September 30, 2025, the Fund had an effective shelf registration available through September 30, 2027, which authorizes issuance of $125 million in common or preferred shares.

The Fund’s Articles of Incorporation authorize the issuance of up to 1,995,000 shares of $0.001 par value Preferred Stock. The Preferred Stock is senior to the common stock and results in the financial leveraging of the common stock. Such leveraging tends to magnify both the risks and opportunities to common stockholders. Dividends on shares of the Preferred Stock are cumulative. The Fund is required by the 1940 Act and by the Fund’s Articles Supplementary to meet certain asset coverage tests with respect to the Preferred Stock. 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 Series G Preferred at the redemption price of $10 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 stockholders 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 and variable rates, which could have either a beneficial or detrimental impact on net investment income and gains available to common stockholders.

On December 29, 2022, the Fund issued 1,500,000 shares of Series G 5.20% Cumulative Preferred Stock, receiving $14,898,306 after the deduction of offering expenses of $101,694. The Series G Preferred has a liquidation value of $10 per share and an annual dividend rate of 5.20%. On December 26, 2023, 860,000 shares of Series G Preferred were put back to the Fund at their liquidation preference of $10 per share. On June 26, 2025, the Fund redeemed all outstanding Series G Preferred at the liquidation preference of $10 per share.

On June 26, 2025, the Fund issued 607,500 shares of Series H 5.20% Cumulative Preferred Stock (Series H Preferred), receiving $6,075,000 after deduction of estimated offering expenses. The Series H Preferred has a liquidation value of $10 per share and an annual dividend rate of 5.20%. The Series H Preferred are subject to mandatory redemption on September 26, 2027. The Series H Preferred are not subject to optional redemption unless such redemption is necessary, in the judgment of the Board, to maintain the Fund’s status as a regulated investment company under Subchapter M of the Internal Revenue Code of 1986, as amended. The Fund will also redeem all or any part of the outstanding Series H Preferred that holders have properly tendered for redemption during each sixty day period prior to June 26, 2026, and March 26, 2027, at the liquidation preference, plus any accumulated and unpaid dividends.

Notes to Financial Statements (Continued)

The holders of preferred stock generally are entitled to one vote per share held on each matter submitted to a vote of stockholders of the Fund and will vote together with holders of common stock as a single class. The holders of Series H Preferred voting together as a single class also have the right currently to elect two Directors and, under certain circumstances, are entitled to elect a majority of the Board. In addition, the affirmative vote of a majority of the votes entitled to be cast by holders of all outstanding shares of the preferred stock, 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 stock 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.

8. Significant Shareholder. As of September 30, 2025, 10.1% of common shares and 51.0% of the preferred shares were beneficially owned by the Adviser and its affiliates, including 25% or greater holders’ managed accounts for which the affiliates of the Adviser have voting control but disclaim pecuniary interest.

9. Convertible Securities Concentration. The Fund will invest at least 80% of its net assets, under normal market conditions, in a combination of convertible securities and income producing securities (the 80% Policy). The Fund expects to continue its practice of focusing on convertible securities to the extent attractive opportunities are available. The 80% Policy may be changed without stockholder approval. However, the Fund has adopted a policy to provide stockholders with notice at least sixty days prior to the implementation of any change in the 80% Policy.

10. 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.

11. Segment Reporting. The Fund’s Principal Executive Officer and Principal Financial Officer 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.

12. 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 subsequent events requiring recognition or disclosure in the financial statements.

SUMMARY OF FUND EXPENSES

The following tables are intended to assist you in understanding the various costs and expenses directly or indirectly associated with investing in our common shares as a percentage of net assets attributable to common shares. The table is based on the capital structure of the Fund as of September 30, 2025.

Shareholder Transaction Expenses |  |  |  |
Sales Load (as a percentage of offering price) |  |  | -(1 | )%(a)
Offering Expenses Borne by the Fund (as a percentage of offering price) |  |  | -(1 | )%(a)
Dividend Reinvestment and Cash Purchase Plan Fees |  |  |  |
Purchase Transaction |  | $ | 0.75 | (b)
Sale Transaction |  | $ | 2.50 | (b)

Annual Expenses |  | Percentages of Net Assets Attributable to Common Shares |
Management Fees |  |  | 1.07 | %(c)
Interest Expense |  |  | 0.36 | %(d)
Other Expenses |  |  | 0.51 | %(e)
Total Annual Fund Operating Expenses |  |  | 1.94 | %
Dividends on Preferred Shares |  |  | — | %
Total Annual Expenses and Dividends on Preferred Shares |  |  | 1.94 | %(e)

| (a) | If common shares are sold to or through underwriters or dealer managers, a prospectus or prospectus supplement will set forth any applicable sales load and the estimated offering expenses borne by the fund.
| (b) | Shareholders participating in the Fund’s Automatic Dividend Reinvestment Plan do not incur any additional fees. Shareholders participating in the Voluntary Cash Purchase Plan would pay $0.75 plus their pro rata share of brokerage commissions for transactions to purchase shares and $2.50 plus their pro rata share of brokerage commissions per transaction to sell shares. See “Automatic Dividend Reinvestment and Voluntary Cash Purchase Plan.”
| (c) | The Investment Adviser’s fee is 1.00% annually of the Fund’s average daily net assets, including the liquidation value of preferred shares. In calculating net assets for this purpose, liabilities does not include amounts attributable to liabilities constituting indebtedness. Consequently, since the Fund has preferred shares or notes outstanding, all else being equal and assuming no application of any voluntary fee waivers, the investment management fees and other expenses as a percentage of net assets attributable to common shares are be higher than if the Fund did not utilize a leveraged capital structure. See “Management of the Fund—General.”
| (d) | The Series H Cumulative Preferred Shares have a mandatory redemption date of September 26, 2027. Therefore, for financial reporting purposes only, the dividends paid on the Series H Cumulative Preferred Shares are included as a component of “interest expense.”

Additional Fund Information (Continued) (Unaudited)

| (e) | “Other Expenses” are based on estimated amounts for the current year.

For a more complete description of the various costs and expenses a common shareholder would bear in connection with the issuance and ongoing maintenance of any preferred shares or notes issued by the Fund, see “Risk Factors and Special Considerations—Special Risks to Holders of Common Shares—Leverage Risk.”

Example

The following example illustrates the expenses you would pay on a $1,000 investment in common shares, assuming a 5% annual portfolio total return.* The actual amounts in connection with any offering will be set forth in a prospectus or prospectus supplement if applicable.

|  | 1 Year |  |  | 3 Year |  |  | 5 Year |  |  | 10 Year |
Total Expenses Incurred |  | $ | 20 |  |  | $ | 61 |  |  | $ | 105 |  |  | $ | 226 |

| * | The example should not be considered a representation of future expenses. The example is based on “Annual Expenses” shown in the table above and assumes that the amounts set forth in the table do not change and that all distributions are reinvested at net asset value. Actual expenses may be greater or less than those assumed. Moreover, the Fund’s actual rate of return may be greater or less than the hypothetical 5% return shown in the example.

The example includes dividends on preferred shares, which for financial reporting purposes only are included as a component of “Interest Expense” in the table above. If dividends on preferred shares were not included in “Interest Expense” and were not included in the example calculation, the expenses for the 1-, 3-, 5- and 10-year periods in the table above would be as follows (based on the same assumptions as above): $16, $50, $86, and $187.

CHANGES OCCURRING DURING THE PRIOR FISCAL PERIOD

The following information is a summary of certain changes during the most recent fiscal year ended September 30, 2025. This information may not reflect all of the changes that have occurred since you purchased shares of the Fund.

During the Fund’s most recent fiscal year, there were no material changes to the Fund’s investment objectives or policies that have not been approved by shareholders or in the principal risk factors associated with an investment in the Fund.

INVESTMENT OBJECTIVES AND POLICIES

Investment Objectives

The investment objective of the Fund is to seek a high level of total return on its assets. The Fund seeks to achieve its investment objective through a combination of current income and capital appreciation. There is no assurance that this objective will be achieved. It is, however, a fundamental policy of the Fund and cannot be changed without stockholder approval.

Under normal circumstances the Fund will invest at least 80% of the value of its total assets (taken at current value) in “convertible securities,” i.e., securities (bonds, debentures, notes, stocks and other similar securities) that are convertible into common stock or other equity securities, and “income securities,” i.e., nonconvertible debt or equity securities having a history of regular payments or accrual of income to holders. Securities received upon conversion of a convertible security will not be included in the calculation of the percentage of Fund assets invested in convertible securities but may be retained in the Fund’s portfolio to permit orderly disposition or to establish long-term holding periods for federal income tax purposes. The Fund expects to continue its practice of focusing on convertible securities to the extent attractive opportunities are available. We cannot assure you that the Fund will achieve its investment objective. The Fund may invest without limit in securities rated below investment grade by recognized statistical rating agencies or unrated securities of comparable quality, including securities of issuers in default, which are likely to have the lowest rating; provided, however, that not more than 50% of the Fund’s portfolio will consist of securities rated CCC or lower by S&P or Caa or lower by Moody’s or, if unrated, are of comparable quality as determined by the Investment Adviser, and the Fund’s investments in securities of issuers in default will be limited to not more than 5% of the total assets of the Fund. Securities rated below investment grade, which may be preferred shares or debt, are predominantly speculative and involve major risk exposure to adverse conditions. Securities that are rated lower than “BBB” by S&P, or lower than “Baa” by Moody’s or unrated securities considered by the Investment Adviser to be of comparable quality, are commonly referred to as “junk bonds” or “high yield” securities.

The Fund may invest up to 25% of its total assets in securities of non-U.S. issuers, which are generally denominated in foreign currencies. The Fund may also purchase sponsored American Depository Receipts (“ADRs”) or U.S. denominated securities of foreign issuers, which will not be included in the Fund’s 25% foreign securities limitation. The Fund has no limit on the amount of its net assets it may invest in unregistered and

32

The Gabelli Convertible and Income Securities Fund Inc.

Additional Fund Information (Continued) (Unaudited)

otherwise illiquid investments; however, the Fund currently does not intend to invest more than 15% of its total net assets in illiquid convertible securities or income securities. The Fund may invest up to 20% of its total assets (taken at current value and subject to any restrictions appearing elsewhere in this Registration Statement) in any combination and quantity of securities that do not generate any income, such as common stocks that do not pay dividends. In selecting any of the foregoing securities for investment, the factors that will be considered by the Investment Adviser include the Investment Adviser’s evaluation of the underlying value of the assets and business of the issuers of the securities, the potential for capital appreciation, the price of the securities, the issuer’s balance sheet characteristics and the perceived skills and integrity of the issuer’s management.

During periods when it is deemed necessary for temporary defensive purposes, the Fund may invest without limit in high quality money market instruments, including commercial paper of domestic and foreign corporations, certificates of deposit, bankers’ acceptances and other obligations of domestic and foreign banks and obligations issued or guaranteed by the United States government, its instrumentalities or agencies and, subject to statutory limitations, unaffiliated money market mutual funds, unless an exemptive order permits the Fund to invest in affiliated money market funds. The yield on these securities will, as a general matter, tend to be lower than the yield on other securities to be purchased by the Fund.

Investment Methodology of the Fund

In selecting securities for the Fund, the Investment Adviser normally considers the following factors, among others:

| ● | the Investment Adviser’s own evaluations of the private market value (as defined below), cash flow, earnings per share and other

| ● | fundamental aspects of the underlying assets and business of the company;

| ● | the interest or dividend income generated by the securities;

| ● | the potential for capital appreciation of the securities and any underlying common stocks;

| ● | the prices of the securities relative to comparable securities;

| ● | whether the securities are entitled to the benefits of call protection or other protective covenants;

| ● | the existence of any anti-dilution protections or guarantees of the security; and

| ● | the diversification of the Fund’s portfolio as to issuers.

The Investment Adviser’s investment philosophy with respect to debt and equity securities is to identify assets that are selling in the public market at a discount to their private market value. The Investment Adviser defines private market value as the value informed purchasers are willing to pay to acquire assets with similar characteristics. The Investment Adviser also normally evaluates an issuer’s free cash flow and long-term earnings trends. Finally, the Investment Adviser looks for a catalyst, something indigenous to the company, its industry or country that will surface additional value.

Certain Investment Practices

Convertible Securities. A convertible security is a bond, debenture, corporate note, preferred stock or other security that may be exchanged or converted into a prescribed amount of common stock or other equity security of the same or a different issuer within a particular period of time at a specified price or formula. A convertible

33

The Gabelli Convertible and Income Securities Fund Inc.

Additional Fund Information (Continued) (Unaudited)

security may also be structured so that it is convertible at the option of the holder or the issuer, or subject to mandatory conversion. Before conversion, convertible securities have the same overall characteristics as non-convertible debt or preferred securities insofar as they generally provide a stable stream of income with generally higher yields than those of common stock of the same or similar issuers. Convertible securities rank senior to common stock in an issuer’s capital structure. They are of a higher credit quality and entail less risk than an issuer’s common stock, although the extent to which such risk is reduced depends in large measure upon the degree to which the convertible security sells above its value as a fixed income security.

The Fund believes that the characteristics of convertible securities make them appropriate investments for an investment company seeking a high level of total return on its assets. These characteristics include the potential for capital appreciation if the value of the underlying common stock increases, the relatively high yield received from dividend or interest payments as compared to common stock dividends and decreased risks of decline in value, relative to the underlying common stock due to their fixed income nature. As a result of the conversion feature, however, the interest rate or dividend preference on a convertible security is generally less than would be the case if the securities were not convertible. During periods of rising interest rates, it is possible that the potential for capital gain on a convertible security may be less than that of a common stock equivalent if the yield on the convertible security is at a level that causes it to sell at a discount.

Every convertible security may be valued, on a theoretical basis, as if it did not have a conversion privilege. This theoretical value is determined by the yield it provides in comparison with the yields of other securities of comparable character and quality that do not have a conversion privilege. This theoretical value, which may change with prevailing interest rates, the credit rating of the issuer and other pertinent factors, often referred to as the “investment value,” represents the security’s theoretical price support level.

“Conversion value” is the amount a convertible security would be worth in market value if it were to be exchanged for the underlying equity security pursuant to its conversion privilege. Conversion value fluctuates directly with the price of the underlying equity security, usually common stock. If, because of low prices for the common stock, the conversion value is substantially below the investment value, the price of the convertible security is governed principally by the factors described in the preceding paragraph. If the conversion value rises near or above its investment value, the price of the convertible security generally will rise above its investment value and, in addition, will sell at some premium over its conversion value. This premium represents the price investors are willing to pay for the privilege of purchasing a fixed-income security with a possibility of capital appreciation due to the conversion privilege. Accordingly, the conversion value of a convertible security is subject to equity risk, that is, the risk that the price of an equity security will fall due to general market and economic conditions, perceptions regarding the industry in which the issuer participates or the issuing company’s particular circumstances. If the appreciation potential of a convertible security is not realized, its conversion value premium may not be recovered.

34

The Gabelli Convertible and Income Securities Fund Inc.

Additional Fund Information (Continued) (Unaudited)

In its selection of convertible securities for the Fund, the Investment Adviser will not emphasize either investment value or conversion value, but will consider both in light of the Fund’s overall investment objective. See “Convertible Securities” below. The Fund may convert a convertible security that it holds:

| ● | when necessary to permit orderly disposition of the investment when a convertible security approaches maturity or has been called for redemption;

| ● | to facilitate a sale of the position;

| ● | if the dividend rate on the underlying common stock increases above the yield on the convertible security; or

| ● | whenever the Investment Adviser believes it is otherwise in the best interests of the Fund.

Convertible securities are generally not investment grade, that is, not rated within the four highest categories by S&P and Moody’s. To the extent that such convertible securities and other nonconvertible debt securities, which are acquired by the Fund consistent with the factors considered by the Investment Adviser as described in this Annual Report, are rated lower than investment grade or are not rated, there would be a greater risk as to the timely repayment of the principal of, and timely payment of interest or dividends on, those securities. It is expected that not more than 50% of the Fund’s portfolio will consist of securities rated CCC or lower by S&P or Caa or lower by Moody’s or, if unrated, are of comparable quality as determined by the Investment Adviser. Those securities and securities rated BB or lower by S&P or Ba or lower by Moody’s are often referred to in the financial press as “junk bonds” and may include securities of issuers in default. “Junk bonds” are considered by the rating agencies to be predominantly speculative and may involve major risk exposure to adverse conditions. See “Risk Factors and Special Considerations-Convertible Securities-Credit Risk.” Securities rated BBB by S&P or Baa by Moody’s, in the opinion of the rating agencies, also have speculative characteristics. Securities need not meet a minimum rating standard in order to be acceptable for investment by the Fund.

The Fund’s investments in securities of issuers in default will be limited to not more than 5% of the total assets of the Fund. Further, the Fund will invest in securities of issuers in default only when the Investment Adviser believes that such issuers will emerge from bankruptcy and the value of such securities will appreciate. By investing in securities of issuers in default the Fund bears the risk that such issuers will not emerge from bankruptcy or that the value of such securities will not appreciate.

The Fund has no independent limit on the amount of its net assets it may invest in unregistered and otherwise illiquid securities and other investments. The current intention of the Investment Adviser is not to invest in excess of 15% of the Fund’s net assets in illiquid convertible securities or income securities. Common stockholders will be notified if the Investment Adviser changes its intention. Investments in unregistered or otherwise illiquid securities entail certain risks related to the fact that they cannot be sold publicly in the United States without registration under the Securities Act. See “Risk Factors and Special Considerations—Asset Class Risks.”

Synthetic Convertible Securities. The Fund may also invest in “synthetic” convertible securities, which, for purposes of its investment policies, the Fund considers to be convertible securities. A “synthetic” convertible security may be created by the Fund or by a third party by combining separate securities that possess the two principal characteristics of a traditional convertible security: an income producing component and a convertible component. Synthetic convertible securities differ from convertible securities whose conversion privilege may be evidenced by warrants attached to the security or acquired as part of a unit with the security. The

35

The Gabelli Convertible and Income Securities Fund Inc.

Additional Fund Information (Continued) (Unaudited)

income-producing component is achieved by investing in non-convertible, income-producing securities such as bonds, preferred stocks and money market instruments. The convertible component is achieved by investing in securities or instruments such as warrants or options to buy common stock at a certain exercise price, or options on a stock index. Unlike a traditional convertible security, which is a single security having a single market value, a synthetic convertible comprises two or more separate securities, each with its own market value. Because the “market value” of a synthetic convertible security is the sum of the values of its income producing component and its convertible component, the value of a synthetic convertible security may respond differently to market fluctuations than a traditional convertible security. The Fund also may purchase synthetic convertible securities created by other parties, including convertible structured notes. Convertible structured notes are income-producing debentures linked to equity. Convertible structured notes have the attributes of a convertible security; however, the issuer of the convertible note (typically an investment bank), rather than the issuer of the underlying common stock into which the note is convertible, assumes credit risk associated with the underlying investment and the Fund in turn assumes credit risk associated with the issuer of the convertible note.

Foreign Securities. The Fund may invest up to 25% of its total assets in securities of non-U.S. issuers, which are generally denominated in foreign currencies.

The Investment Adviser believes that investing in foreign securities offers both enhanced investment opportunities and additional risks beyond those present in U.S. securities. Investing in foreign securities may provide increased diversification by adding securities from various foreign countries (i) that offer different investment opportunities, (ii) that generally are affected by different economic trends and (iii) whose stock markets may not be correlated with U.S. markets. At the same time, these opportunities and trends involve risks that may not be encountered in U.S. investments.

The following considerations comprise both risks and opportunities not typically associated with investing in U.S. securities: fluctuations in exchange rates of foreign currencies; possible imposition of exchange control regulations or currency restrictions that would prevent cash from being brought back to the United States; less public information with respect to issuers of securities; less government supervision of stock exchanges, securities brokers and issuers of securities; lack of uniform accounting, auditing and financial reporting standards; lack of uniform settlement periods and trading practices; less liquidity and frequently greater price volatility in foreign markets than in the United States; possible imposition of foreign taxes; the possibility of expropriation or confiscatory taxation, seizure or nationalization of foreign bank deposits or other assets; the adoption of foreign government restrictions and other adverse political, social or diplomatic developments that could affect investment; difficulty in obtaining or enforcing a court judgment abroad; sometimes less advantageous legal, operational and financial protections applicable to foreign sub-custodial arrangements; and the historically lower level of responsiveness of foreign management to shareholder concerns (such as dividends and return on investment).

American Depositary Receipts. The Fund may invest in American Depositary Receipts (“ADRs”). Such investment may entail certain risks similar to foreign securities. ADRs are certificates representing an ownership interest in a security or a pool of securities issued by a foreign issuer and deposited with the depositary, typically a bank, and held in trust for the investor. The economies of many of the countries in which the issuer of a security underlying an ADR principally engages in business may not be as developed as the United States’ economy and may be subject to significantly different forces. Political or social instability, expropriation or confiscatory

36

Additional Fund Information (Continued) (Unaudited)

taxation, and limitations on the removal of funds or other assets could adversely affect the value of the Fund’s investments in such securities. The value of the securities underlying ADRs could fluctuate as exchange rates change between U.S. dollars and the currency of the country in which the foreign company is located. In addition, foreign companies are not registered with the SEC and are generally not subject to the regulatory controls imposed on U.S. issuers and, as a consequence, there is generally less publicly available information about foreign companies than is available about domestic companies. Foreign companies are not subject to uniform accounting, auditing and financial reporting standards, practices and requirements comparable to those applicable to domestic companies.

Emerging Market Countries. The risks described above for foreign securities, including the risks of nationalization and expropriation of assets, are typically increased to the extent that the Fund invests in companies headquartered in developing, or emerging market, countries. Investments in securities of companies headquartered in such countries may be considered speculative and subject to certain special risks. The political and economic structures in many of these countries may be in their infancy and developing rapidly, and such countries may lack the social, political and economic characteristics of more developed countries. Certain of these countries have in the past failed to recognize private property rights and have at times nationalized and expropriated the assets of private companies. Some countries have inhibited the conversion of their currency to another. The currencies of certain emerging market countries have experienced devaluation relative to the U.S. dollar, and future devaluations may adversely affect the value of the Fund’s assets denominated in such currencies. Some emerging market countries have experienced substantial rates of inflation for many years. Continued inflation may adversely affect the economies and securities markets of such countries. In addition, unanticipated political or social developments may affect the value of the Fund’s investments in these countries and the availability of the Fund of additional investments in these countries. The small size, limited trading volume and relative inexperience of the securities markets in these countries may make the Fund’s investments in such countries illiquid and more volatile than investments in more developed countries, and the Fund may be required to establish special custodial or other arrangements before making investments in these countries. There may be little financial or accounting information available with respect to companies located in these countries, and it may be difficult as a result to assess the value or prospects of an investment in such companies.

Income Securities. Although it is the Fund’s policy to invest in convertible securities to the extent attractive opportunities are available, the Fund may also invest in income securities other than convertible securities that are expected to periodically accrue or generate income for their holders. Such income securities include (i) fixed income securities such as bonds, debentures, notes, preferred stock, short-term discounted Treasury Bills or certain securities of the U.S. government sponsored instrumentalities, as well as money market mutual funds that invest in those securities, which, in the absence of an applicable exemptive order, will not be affiliated with the Investment Adviser, and (ii) common and preferred stocks of issuers that have historically paid periodic dividends. Fixed income securities obligate the issuer to pay to the holder of the security a specified return, which may be either fixed or reset periodically in accordance with the terms of the security. Fixed income securities generally are senior to an issuer’s common stock and their holders generally are entitled to receive amounts due before any distributions are made to common stockholders. Common stocks, on the other hand, generally do not obligate an issuer to make periodic distributions to holders.

37

The Gabelli Convertible and Income Securities Fund Inc.

Additional Fund Information (Continued) (Unaudited)

The market value of fixed income securities, especially those that provide a fixed rate of return, may be expected to rise and fall inversely with interest rates and in general is affected by the credit rating of the issuer, the issuer’s performance and perceptions of the issuer in the market place. The market value of callable or redeemable fixed income securities may also be affected by the issuer’s call and redemption rights. In addition, it is possible that the issuer of fixed income securities may not be able to meet its interest or principal obligations to holders. Further, holders of non-convertible fixed income securities do not participate in any capital appreciation of the issuer.

The Fund may also invest in obligations of government sponsored instrumentalities. Unlike non-U.S. government securities, obligations of certain agencies and instrumentalities of the U.S. government, such as the Government National Mortgage Association, are supported by the “full faith and credit” of the U.S. government; others, such as those of the Export-Import Bank of the U.S., are supported by the right of the issuer to borrow from the U.S. Treasury; others, such as those of the Federal National Mortgage Association, are supported by the discretionary authority of the U.S. government to purchase the agency’s obligations; and still others, such as those of the Student Loan Marketing Association, are supported only by the credit of the instrumentality. No assurance can be given that the U.S. government would provide financial support to U.S. government sponsored instrumentalities if it is not obligated to do so by law. Although the Fund may invest in all types of obligations of agencies and instrumentalities of the U.S. government, the Fund currently intends to invest only in obligations that are supported by the “full faith and credit” of the U.S. government.

The Fund also may invest in common stock of issuers that have historically paid periodic dividends or otherwise made distributions to common stockholders. Unlike fixed income securities, dividend payments generally are not guaranteed and so may be discontinued by the issuer at its discretion or because of the issuer’s inability to satisfy its liabilities. Further, an issuer’s history of paying dividends does not guarantee that it will continue to pay dividends in the future. In addition to dividends, under certain circumstances the holders of common stock may benefit from the capital appreciation of the issuer.

Common stocks represent the residual ownership interest in the issuer and holders of common stock are entitled to the income and increase in the value of the assets and business of the issuer after all of its debt obligations and obligations to preferred shareholders are satisfied. Common stocks generally have voting rights.

Common stocks fluctuate in price in response to many factors including historical and prospective earnings of the issuer, the value of its assets, general economic conditions, interest rates, investor perceptions and market liquidity.

Non-Investment Grade Securities. The Fund may invest in securities rated below investment grade by recognized rating agencies or unrated securities of comparable quality. The prices of these lower grade securities are more sensitive to negative developments, such as a decline in the issuer’s revenues or a general economic downturn, than are the prices of higher grade securities. Securities of below investment grade quality—those securities rated below “Baa” by Moody’s or below “BBB” by S&P (or unrated securities of comparable quality)—are predominantly speculative with respect to the issuer’s capacity to pay interest and repay principal when due and therefore involve a greater risk of default. Securities rated below investment grade commonly are referred to as “junk bonds” or “high yield” securities and generally pay a premium above the yields of U.S.

38

The Gabelli Convertible and Income Securities Fund Inc.

Additional Fund Information (Continued) (Unaudited)

government securities or securities of investment grade issuers because they are subject to greater risks than these securities. These risks, which reflect their speculative character, include the following:

| ● | greater volatility;

| ● | greater credit risk and risk of default;

| ● | potentially greater sensitivity to general economic or industry conditions;

| ● | potential lack of attractive resale opportunities (illiquidity); and

| ● | additional expenses to seek recovery from issuers who default.

In addition, the prices of these non-investment grade securities are more sensitive to negative developments, such as a decline in the issuer’s revenues or a general economic downturn, than are the prices of higher grade securities. Non-investment grade securities tend to be less liquid than investment grade securities. The market value of non-investment grade securities may be more volatile than the market value of investment grade securities and generally tends to reflect the market’s perception of the creditworthiness of the issuer and short term market developments to a greater extent than investment grade securities, which primarily reflect fluctuations in general levels of interest rates.

Ratings are relative and subjective, and not absolute standards of quality. Securities ratings are based largely on the issuer’s historical financial condition and the rating agencies’ analysis at the time of rating. Consequently, the rating assigned to any particular security is not necessarily a reflection of the issuer’s current financial condition.

The Fund may purchase securities of companies that are experiencing significant financial or business difficulties, including companies involved in bankruptcy or other reorganization and liquidation proceedings. Although such investments may result in significant financial returns to the Fund, they involve a substantial degree of risk. The level of analytical sophistication, both financial and legal, necessary for successful investments in issuers experiencing significant business and financial difficulties is unusually high. There can be no assurance that the Fund will correctly evaluate the value of the assets collateralizing its investments or the prospects for a successful reorganization or similar action. In any reorganization or liquidation proceeding relating to a portfolio investment, the Fund may lose all or part of its investment or may be required to accept collateral with a value less than the amount of the Fund’s initial investment.

As a part of its investments in non-investment grade securities, the Fund may invest in the securities of issuers in default. The Fund invests in securities of issuers in default only when the Investment Adviser believes that such issuers will honor their obligations and emerge from bankruptcy protection and that the value of such issuers’ securities will appreciate. By investing in the securities of issuers in default, the Fund bears the risk that these issuers will not continue to honor their obligations or emerge from bankruptcy protection or that the value of these securities will not otherwise appreciate.

In addition to using recognized rating agencies and other sources, the Investment Adviser will also perform its own analysis of issuers in seeking investments that it believes to be underrated (and thus higher yielding) in light of the financial condition of the issuer. Its analysis of issuers may include, among other things, current and anticipated cash flow and borrowing requirements, value of assets in relation to historical cost, strength of management, responsiveness to business conditions, credit standing and current anticipated results of

39

The Gabelli Convertible and Income Securities Fund Inc.

Additional Fund Information (Continued) (Unaudited)

operations. In selecting investments for the Fund, the Investment Adviser may also consider general business conditions, anticipated changes in interest rates and the outlook for specific industries.

Subsequent to its purchase by the Fund, an issue of securities may cease to be rated or its rating may be reduced. In addition, it is possible that recognized rating agencies might change their ratings of a particular issue to reflect subsequent events on a timely basis. Moreover, such ratings do not assess the risk of a decline in market value. None of these events will require the sale of the securities by the Fund, although the Investment Adviser will consider these events in determining whether the Fund should continue to hold the securities.

Income securities, including non-investment grade securities and comparable unrated securities, frequently have call or buy-back features that permit their issuers to call or repurchase the securities from their holders, such as the Fund. If an issuer exercises these rights during periods of declining interest rates, the Fund may have to replace the security with a lower yielding security, thus resulting in a decreased return for the Fund.

The market for non-investment grade and comparable unrated securities has at various times, particularly during times of economic recession, experienced substantial reductions in market value and liquidity. Past recessions have adversely affected the value of such securities as well as the ability of certain issuers of such securities to repay principal and pay interest thereon or to refinance such securities. The market for those securities could react in a similar fashion in the event of any future economic recession.

Value Investing. The Fund’s portfolio manager will use various value methods in managing its assets. In selecting securities for the Fund, he evaluates the quality of a company’s balance sheet, the level of its cash flows and other measures of a company’s financial condition and profitability. The portfolio manager may also consider other factors, such as a company’s unrecognized asset values, its future growth prospects or its turnaround potential following an earnings disappointment or other business difficulties. The portfolio manager then uses these factors to assess the company’s current worth, basing this assessment on either what he believes a knowledgeable buyer might pay to acquire the entire company or what he thinks the value of the company should be in the stock market.

The Fund’s portfolio manager generally invests in securities of companies that are trading significantly below his estimate of the company’s current worth in an attempt to reduce the risk of overpaying for such companies. Seeking long term growth of capital, he also evaluates the prospects for the market price of the company’s securities to increase over a two- to five-year period toward this estimate.

The Investment Adviser’s value approach strives to reduce some of the other risks of investing in the securities of smaller companies (for the Fund’s portfolio taken as a whole) by evaluating other risk factors. For example, its portfolio manager generally attempts to lessen financial risk by buying companies with strong balance sheets and low leverage.

While there can be no assurance that this risk-averse value approach will be successful, the Investment Adviser believes that it can reduce some of the risks of investing.

Although the Investment Adviser’s approach to security selection seeks to reduce downside risk to the Fund’s portfolio, especially during periods of broad stock market declines, it may also potentially have the effect of limiting gains in strong up markets.

Risk Arbitrage. Subject to the requirement of investing at least 80% of its assets in convertible or income securities, the Fund may invest without limitation in securities pursuant to “risk arbitrage” strategies or in other investment funds managed pursuant to such strategies. Risk arbitrage investments are made in securities of companies for which a tender or exchange offer has been made or announced and in securities of companies for which a merger, consolidation, liquidation or reorganization proposal has been announced if, in the judgment of the Investment Adviser, there is a reasonable prospect of total return significantly greater than the brokerage and other transaction expenses involved. Risk arbitrage strategies attempt to exploit merger activity to capture the spread between current market values of securities and their values after successful completion of a merger, restructuring or similar corporate transaction. Transactions associated with risk arbitrage strategies typically involve the purchases or sales of securities in connection with announced corporate actions which may include, but are not limited to, mergers, consolidations, acquisitions, transfers of assets, tender offers, exchange offers, re-capitalizations, liquidations, divestitures, spin-offs and similar transactions. However, a merger or other restructuring or tender or exchange offer anticipated by the Fund and in which it holds an arbitrage position may not be completed on the terms contemplated or within the time frame anticipated, resulting in losses to the Fund.

In general, securities which are the subject of such an offer or proposal sell at a premium to their historic market price immediately prior to the announcement of the offer but may trade at a discount or premium to what the stated or appraised value of the security would be if the contemplated transaction were approved or consummated.

Such investments may be advantageous when the discount significantly overstates the risk of the contingencies involved; significantly undervalues the securities, assets or cash to be received by shareholders as a result of the contemplated transaction; or fails adequately to recognize the possibility that the offer or proposal may be replaced or superseded by an offer or proposal of greater value. The evaluation of such contingencies requires unusually broad knowledge and experience on the part of the Investment Adviser which must appraise not only the value of the issuer and its component businesses as well as the assets or securities to be received as a result of the contemplated transaction but also the financial resources and business motivation behind the offer and/or the dynamics and business climate when the offer or proposal is in process. Since such investments are ordinarily short term in nature, they will tend to increase the turnover ratio of the Fund, thereby increasing its brokerage and other transaction expenses. Risk arbitrage strategies may also involve short selling, options hedging and other arbitrage techniques to capture price differentials.

Forward Foreign Currency Exchange Contracts. Subject to guidelines of our Board of Directors, the Fund may enter into forward foreign currency exchange contracts to protect the value of its portfolio against uncertainty in the level of future currency exchange rates between a particular foreign currency and the U.S. dollar or between foreign currencies in which its securities are or may be denominated. The Fund may enter into such contracts on a spot (i.e., cash) basis at the rate then prevailing in the currency exchange market or on a forward basis by entering into a forward contract to purchase or sell currency. A forward contract on foreign currency is an obligation to purchase or sell a specific currency at a future date, which may be any fixed number of days agreed upon by the parties from the date of the contract at a price set on the date of the contract. Forward currency contracts (i) are traded in a market conducted directly between currency traders (typically, commercial banks or other financial institutions) and their customers, (ii) generally have no deposit requirements and (iii)

41

The Gabelli Convertible and Income Securities Fund Inc.

Additional Fund Information (Continued) (Unaudited)

are typically consummated without payment of any commissions. The Fund, however, may enter into forward currency contracts requiring deposits or involving the payment of commissions. The Fund expects to invest in forward currency contracts for hedging or currency risk management purposes and not in order to speculate on currency exchange rate movements. The Fund will only enter into forward currency contracts with parties which it believes to be creditworthy.

In hedging a specific transaction, the Fund may enter into a forward contract with respect to either the currency in which the transaction is denominated or another currency deemed appropriate by the Investment Adviser. The amount the Fund may invest in forward currency contracts is limited to the amount of its aggregate investments in foreign currencies. The use of forward currency contracts may involve certain risks, including the failure of the counterparty to perform its obligations under the contract, and such use may not serve as a complete hedge because of an imperfect correlation between movements in the prices of the contracts and the prices of the currencies hedged or used for cover. The Fund will only enter into forward currency contracts with parties that the Investment Adviser believes to be creditworthy institutions.

Restricted and Illiquid Securities. The Fund may invest without limit in securities for which there is no readily available trading market or are otherwise illiquid; however, the Fund currently does not intend to invest more than 15% of its total net assets in illiquid convertible securities or income securities. Illiquid securities include securities legally restricted as to resale, such as commercial paper issued pursuant to Section 4(a)(2) of the Securities Act and securities eligible for resale pursuant to Rule 144A thereunder. Section 4(a)(2) and Rule 144A securities may, however, be treated as liquid by the Investment Adviser pursuant to procedures adopted by the Board, which require consideration of factors such as trading activity, availability of market quotations and number of dealers willing to purchase the security. If the Fund invests in Rule 144A securities, the level of portfolio illiquidity may be increased to the extent that eligible buyers become uninterested in purchasing such securities.

It may be difficult to sell such securities at a price representing the fair value until such time as such securities may be sold publicly. Where registration is required, a considerable period may elapse between a decision to sell the securities and the time when it would be permitted to sell. Thus, the Fund may not be able to obtain as favorable a price as that prevailing at the time of the decision to sell. The Fund may also acquire securities through private placements under which it may agree to contractual restrictions on the resale of such securities. Such restrictions might prevent their sale at a time when such sale would otherwise be desirable.

Leverage. As provided in the 1940 Act and subject to certain exceptions, the Fund may issue senior securities (which may be additional classes of stock, such as preferred shares, or securities representing debt) so long as its total assets, less certain ordinary course liabilities, exceed 300% of the amount of the debt outstanding and exceed 200% of the amount of preferred shares and debt outstanding. The use of leverage magnifies the impact of changes in net asset value, which means that, all else being equal, the use of leverage results in outperformance on the upside and underperformance on the downside. In addition, if the cost of leverage exceeds the return on the securities acquired with the proceeds of leverage, the use of leverage will diminish rather than enhance the return to the Fund. The use of leverage generally increases the volatility of returns to the Fund. Such volatility may increase the likelihood of the Fund having to sell investments in order to meet its obligations to make distributions on the preferred shares or principal or interest payments on debt securities, or to redeem preferred shares or repay debt, when it may be disadvantageous to do so. The Fund’s use of

42

The Gabelli Convertible and Income Securities Fund Inc.

Additional Fund Information (Continued) (Unaudited)

leverage may require it to sell portfolio investments at inopportune times in order to raise cash to redeem preferred shares or otherwise de-leverage so as to maintain required asset coverage amounts or comply with any mandatory redemption terms of any outstanding preferred shares. See “Risk Factors and Special Considerations—Leverage Risk.”

In the event the Fund had both outstanding preferred shares and senior securities representing debt at the same time, the Fund’s obligations to pay dividends or distributions and, upon liquidation of the Fund, liquidation payments in respect of its preferred shares would be subordinate to the Fund’s obligations to make any principal and/or interest payments due and owing with respect to its outstanding senior debt securities. Accordingly, the Fund’s issuance of senior securities representing debt would have the effect of creating special risks for the Fund’s preferred shareholders that would not be present in a capital structure that did not include such securities. See “Risk Factors and Special Considerations—Special Risks Related to Preferred Securities.”

Subject to the requirements of Rule 18f-4 under the 1940 Act (“Rule 18f-4”), the Fund may enter into derivative transactions, including transactions that have economic leverage embedded in them. Rule 18f-4 defines “derivatives transactions” as (1) any swap, security-based swap, futures contract, forward contract, option, any combination of the foregoing, or any similar instrument, under which a fund is or may be required to make any payment or delivery of cash or other assets during the life of the instrument or at maturity or early termination, whether as margin or settlement payment or otherwise; and (2) any short sale borrowing. Derivatives transactions entered into by the Fund in compliance with Rule 18f-4 will not be considered senior securities for purposes of computing the asset coverage requirements described above. Economic leverage exists when the Fund achieves the right to a return on a capital base that exceeds the investment which the Fund has contributed to the instrument achieving a return. Derivative transactions that the Fund may enter into and the risks associated with them are described elsewhere in this Annual Report. The Fund cannot assure you that investments in derivative transactions that have economic leverage embedded in them will result in a higher return on its common shares.

If the Fund enters into any reverse repurchase agreement or similar financing transactions obligating the Fund to make future payments, the Fund must either treat all such transactions as derivatives transactions for all purposes under Rule 18f-4 or otherwise comply with the asset coverage requirements described above and combine the aggregate amount of indebtedness associated with all such transactions with the aggregate amount of any other senior securities representing indebtedness when calculating the Fund’s asset coverage ratio limit requirements. The asset coverage requirements under section 18 of the 1940 Act and the limits and conditions imposed by Rule 18f-4 may limit or restrict portfolio management.

Options. The Fund may purchase or sell, i.e., write, options on securities, securities indices and foreign currencies which are listed on a national securities exchange or in the OTC market as a means of achieving additional return or of hedging the value of the Fund’s portfolio. A call option is a contract that, in return for a premium, gives the holder of the option the right to buy from the writer of the call option the security or currency underlying the option at a specified exercise price at any time during the term of the option. The writer of the call option has the obligation, upon exercise of the option, to deliver the underlying security or currency upon payment of the exercise price during the option period. A put option is the reverse of a call option, giving the holder of the option the right, in return for a premium, to sell the underlying security to the writer, at a specified

43

The Gabelli Convertible and Income Securities Fund Inc.

Additional Fund Information (Continued) (Unaudited)

price, and obligating the writer to purchase the underlying security from the holder upon exercise of the exercise price.

If the Fund has written an option, it may terminate its obligation by effecting a closing purchase transaction. This is accomplished by purchasing an option of the same series as the option previously written. However, with respect to exchange-traded options, once the Fund has been assigned an exercise notice, the Fund will be unable to effect a closing purchase transaction. Similarly, if the Fund is the holder of an option it may liquidate its position by effecting a closing sale transaction on an exchange. This is accomplished by selling an option of the same series as the option previously purchased. There can be no assurance that either a closing purchase or sale transaction can be effected when the Fund so desires.

The Fund will realize a profit from a closing transaction if the price of the transaction is less than the premium received from writing the option or is more than the premium paid to purchase the option; the Fund will realize a loss from a closing transaction if the price of the transaction is more than the premium received from writing the option or is less than the premium paid to purchase the option. Since call option prices generally reflect increases in the price of the underlying security, any loss resulting from the repurchase of a call option may also be wholly or partially offset by unrealized appreciation of the underlying security. Other principal factors affecting the market value of a put or a call option include supply and demand, prevailing interest rates, the current market price and price volatility of the underlying security, and the time remaining until the expiration date of the option. Gains and losses on investments in options depend, in part, on the ability of the Investment Adviser to predict correctly the effect of these factors. The use of options cannot serve as a complete hedge since the price movement of securities underlying the options will not necessarily follow the price movements of the portfolio securities subject to the hedge.

An option position may be closed out only on an exchange which provides a secondary market for an option of the same series or in a private transaction. Although the Fund will generally purchase or write only those options for which there appears to be an active secondary market, there is no assurance that a liquid secondary market on an exchange will persist for any particular option. In such event, it might not be possible to effect closing transactions in particular options, so that the Fund would have to exercise its options in order to realize any profit and would incur brokerage commissions upon the exercise of call options and upon the subsequent disposition of underlying securities for the exercise of put options.

Although the Investment Adviser will attempt to take appropriate measures to minimize the risks relating to the Fund’s writing of put and call options, there can be no assurance that the Fund will succeed in any option-writing program it undertakes.

The Fund will not purchase options if, as a result, the aggregate cost of all outstanding options exceed 10% of the Fund’s total assets.

Futures Contracts and Options on Futures. The Fund may purchase and sell financial futures contracts and options thereon which are traded on a commodities exchange or board of trade for certain hedging, yield enhancement and risk management purposes. A financial futures contract is an agreement to purchase or sell an agreed amount of securities or currencies at a set price for delivery in the future. These futures contracts and related options may be on debt securities, financial indices, securities indices, U.S. government securities and

44

The Gabelli Convertible and Income Securities Fund Inc.

Additional Fund Information (Continued) (Unaudited)

foreign currencies. The Investment Adviser has claimed an exclusion from the definition of the term “commodity pool operator” under the Commodity Exchange Act.

When Issued, Delayed Delivery Securities and Forward Commitments. The Fund may enter into forward commitments for the purchase or sale of securities, including on a “when issued” or “delayed delivery” basis, in excess of customary settlement periods for the type of security involved. In some cases, a forward commitment may be conditioned upon the occurrence of a subsequent event, such as approval and consummation of a merger, corporate reorganization or debt restructuring (i.e., a when, as and if issued security). When such transactions are negotiated, the price is fixed at the time of the commitment, with payment and delivery taking place in the future, generally a month or more after the date of the commitment. While it will only enter into a forward commitment with the intention of actually acquiring the security, the Fund may sell the security before the settlement date if it is deemed advisable by the Investment Adviser.

Securities purchased under a forward commitment are subject to market fluctuation, and no interest (or dividends) accrues to the Fund prior to the settlement date.

Short Sales Against the Box. The Fund may from time to time make short sales of securities it owns or has the right to acquire through conversion or exchange of other securities it owns. A short sale is “against the box” to the extent that the Fund contemporaneously owns or has the right to obtain at no added cost securities identical to those sold short. In a short sale, the Fund does not immediately deliver the securities sold or receive the proceeds from the sale. The Fund may not make short sales or maintain a short position if it would cause more than 25% of the Fund’s total assets, taken at market value, to be held as collateral for such sales.

The Fund may close out a short position by purchasing and delivering an equal amount of the securities sold short, rather than by delivering securities already held by the Fund, because the Fund may want to continue to receive interest and dividend payments on securities in its portfolio that are convertible into the securities sold short.

The Fund may make a short sale in order to hedge against market risks when it believes that the price of a security may decline, causing a decline in the value of a security owned by the Fund or a security convertible into, or exchangeable for, such security, or when the Fund does not want to sell the security it owns. Such short sale transactions may be subject to special tax rules, one of the effects of which may be to accelerate income to the Fund. Additionally, the Fund may use short sales in conjunction with the purchase of a convertible security when it is determined that a convertible security can be bought at a small conversion premium and has a yield advantage relative to the underlying common stock sold short.

Other Derivative Instruments. The Fund may also utilize other types of derivative instruments, primarily for hedging or risk management purposes. These instruments include futures, forward contracts, options on such contracts and interest rate, total return and other kinds of swaps. For a further description of such derivative instruments, see below.

Limitations on the Purchase and Sale of Futures Contracts, Certain Options, and Swaps. Subject to the guidelines of the Board, the Fund may engage in “commodity interest” transactions (generally, transactions in futures, certain options, certain currency transactions, and certain types of swaps) only for bona fide hedging or other permissible transactions in accordance with the rules and regulations of the Commodity Futures Trading

45

The Gabelli Convertible and Income Securities Fund Inc.

Additional Fund Information (Continued) (Unaudited)

Commission (“CFTC”). Pursuant to amendments by the CFTC to Rule 4.5 under the Commodity Exchange Act (“CEA”), the Investment Adviser has filed a notice of exemption from registration as a “commodity pool operator” with respect to the Fund. The Fund and the Investment Adviser are therefore not subject to registration or regulation as a commodity pool operator under the CEA. In addition, certain trading restrictions are applicable to the Fund as a result of this status. These trading restrictions permit the Fund to engage in commodity interest transactions that include (i) “bona fide hedging” transactions, as that term is defined and interpreted by the CFTC and its staff, without regard to the percentage of the Fund’s assets committed to margin and options premiums and (ii) non-bona fide hedging transactions, provided that the Fund does not enter into such non-bona fide hedging transactions if, immediately thereafter, either (a) the sum of the amount of initial margin deposits on the Fund’s existing futures positions or swaps positions and option or swaption premiums would exceed 5% of the market value of the Fund’s liquidating value, after taking into account unrealized profits and unrealized losses on any such transactions, or (b) the aggregate net notional value of the Fund’s commodity interest transactions would not exceed 100% of the market value of the Fund’s liquidating value, after taking into account unrealized profits and unrealized losses on any such transactions. In addition to meeting one of the foregoing trading limitations, the Fund may not market itself as a commodity pool or otherwise as a vehicle for trading in the futures, options or swaps markets. Therefore, in order to claim the Rule 4.5 exemption, the Fund is limited in its ability to invest in commodity futures, options, and certain types of swaps (including securities futures, broad based stock index futures, and financial futures contracts). As a result, the Fund is more limited in its ability to use these instruments than in the past, and these limitations may have a negative impact on the ability of the Investment Adviser to manage the Fund, and on the Fund’s performance. If the Investment Adviser was required to register as a commodity pool operator with respect to the Fund, compliance with additional registration and regulatory requirements would increase Fund expenses. Other potentially adverse regulatory initiatives could also develop.

Risks of Currency Transactions. Currency transactions are also subject to risks different from those of other portfolio transactions. Because currency control is of great importance to the issuing governments and influences economic planning and policy, purchases and sales of currency and related instruments can be adversely affected by government exchange controls, limitations or restrictions on repatriation of currency, and manipulation, or exchange restrictions imposed by governments. These forms of governmental action can result in losses to the Fund if it is unable to deliver or receive currency or monies in settlement of obligations and could also cause hedges it has entered into to be rendered useless, resulting in full currency exposure and incurring transaction costs.

Repurchase Agreements. Repurchase agreements may be seen as loans by the Fund collateralized by underlying debt securities. Under the terms of a typical repurchase agreement, the Fund would acquire an underlying debt obligation for a relatively short period (usually not more than one week) subject to an obligation of the seller to repurchase, and the Fund to resell, the obligation at an agreed price and time. This arrangement results in a fixed rate of return to the Fund that is not subject to market fluctuations during the holding period. The Fund bears a risk of loss in the event that the other party to a repurchase agreement defaults on its obligations and the Fund is delayed in or prevented from exercising its rights to dispose of the collateral securities, including the risk of a possible decline in the value of the underlying securities during the period in which it seeks to assert these rights. The Investment Adviser, acting under the supervision of the Board of Directors, reviews the creditworthiness of those banks and dealers with which the Fund enters into repurchase agreements to evaluate

46

The Gabelli Convertible and Income Securities Fund Inc.

Additional Fund Information (Continued) (Unaudited)

these risks, and monitors on an ongoing basis the value of the securities subject to repurchase agreements to ensure that the value is maintained at the required level. The Fund will not enter into repurchase agreements with the Investment Adviser or any of its affiliates.

Swaps. The Fund may enter into total rate of return, credit default or other types of swaps and related derivatives for various purposes, including to gain economic exposure to an asset or group of assets that may be difficult or impractical to acquire or for hedging and risk management. These transactions generally provide for the transfer from one counterparty to another of certain risks inherent in the ownership of a financial asset such as a common stock or debt instrument. Such risks include, among other things, the risk of default and insolvency of the obligor of such asset, the risk that the credit of the obligor or the underlying collateral will decline or the risk that the common stock of the underlying issuer will decline in value. The transfer of risk pursuant to a derivative of this type may be complete or partial, and may be for the life of the related asset or for a shorter period. These derivatives may be used as a risk management tool for a pool of financial assets, providing the Fund with the opportunity to gain or reduce exposure to one or more reference securities or other financial assets (each, a “Reference Asset”) without actually owning or selling such assets in order, for example, to increase or reduce a concentration risk or to diversify a portfolio. Conversely, these derivatives may be used by the Fund to reduce exposure to an owned asset without selling it.

Because the Fund would not own the Reference Assets, the Fund may not have any voting rights with respect to the Reference Assets, and in such cases all decisions related to the obligors or issuers of the Reference Assets, including whether to exercise certain remedies, will be controlled by the swap counterparties.

Total rate of return swap agreements are contracts in which one party agrees to make periodic payments to another party based on the change in market value of the assets underlying the contract, which may include a specified security, basket of securities or securities indices during the specified period, in return for periodic payments based on a fixed or variable interest rate or the total return from other underlying assets.

A credit default swap consists of an agreement between two parties in which the “buyer” agrees to pay to the “seller” a periodic stream of payments over the term of the contract and the seller agrees to pay the buyer the par value (or other agreed-upon value) of a referenced debt obligation upon the occurrence of a credit event with respect to the issuer of the referenced debt obligation. Generally, a credit event means bankruptcy, failure to pay, obligation acceleration or modified restructuring. The Fund may be either the buyer or seller in a credit default swap. As the buyer in a credit default swap, the Fund would pay to the counterparty the periodic stream of payments. If no default occurs, the Fund would receive no benefit from the contract. As the seller in a credit default swap, the Fund would receive the stream of payments but would be subject to exposure on the notional amount of the swap, which it would be required to pay in the event of a credit event with respect to the issuer of the referenced debt obligation.

The Fund may also enter into equity contract for difference swap transactions. In an equity contract for difference swap, a set of future cash flows is exchanged between two counterparties. One of these cash flow streams will typically be based on a reference interest rate combined with the performance of a notional value of shares of a stock. The other will be based on the performance of the shares of a stock. Depending on the general state of short term interest rates and the returns on the Fund’s portfolio securities at the time an equity contract for difference swap transaction reaches its scheduled termination date, there is a risk that the Fund will not be

47

The Gabelli Convertible and Income Securities Fund Inc.

Additional Fund Information (Continued) (Unaudited)

able to obtain a replacement transaction or that the terms of the replacement will not be as favorable as on the expiring transaction.

Total rate of return swaps and similar derivatives are subject to many risks, including the possibility that the market will move in a manner or direction that would have resulted in gain for the Fund had the swap or other derivative not been utilized (in which case it would have been better had the Fund not engaged in the hedging transactions), the risk of imperfect correlation between the risk sought to be hedged and the derivative transactions utilized, the possible inability of the counterparty to fulfill its obligations under the swap and potential illiquidity of the hedging instrument utilized, which may make it difficult for the Fund to close out or unwind one or more hedging transactions.

Total rate of return swaps and related derivatives are a relatively recent development in the financial markets. Consequently, there are certain legal, tax and market uncertainties that present risks in entering into such arrangements.

There is currently little or no case law or litigation characterizing total rate of return swaps or related derivatives, interpreting their provisions, or characterizing their tax treatment. In addition, additional regulations and laws may apply to these types of derivatives that have not previously been applied. There can be no assurance that future decisions construing similar provisions to those in any swap agreement or other related documents or additional regulations and laws will not have an adverse effect on the Fund that utilizes these instruments. The Fund will monitor these risks and seek to utilize these instruments in a manner that does not lead to undue risk regarding the tax or other structural elements of the Fund. The Fund will not invest in these types of instruments if the Reference Assets are commodities except for bona fide hedging or risk management purposes.

Significant Holdings. The Fund may invest up to 25% of its total assets in securities of issuers in a single industry; however, the Fund does not currently focus and has no current intent to focus on any particular industry or sector. See “Risk Factors and Special Considerations—General Risks—Significant Holdings Risk.”

Investment Restrictions. The Fund has adopted certain investment restrictions as fundamental policies of the Fund. Under the 1940 Act, a fundamental policy may not be changed without the vote of a majority, as defined in the 1940 Act, of the outstanding voting securities of the Fund (voting together as a single class). In addition, pursuant to the Fund’s Series G Articles Supplementary, a majority, as defined in the 1940 Act, of the outstanding preferred shares of the Fund (voting separately as a single class) is also required to change a fundamental policy. The Fund may become subject to rating agency guidelines that are more limiting than its current investment restrictions in order to obtain and maintain a desired rating on its preferred shares, if any.

The Fund’s investment objective is a fundamental policy. Except as expressly listed under “Investment Restrictions” herein, none of the Fund’s other policies is fundamental, and each may be modified by the Board without shareholder approval.

Temporary Defensive Investments. When a temporary defensive posture is believed by the Investment Adviser to be warranted (“temporary defensive periods”), the Fund may invest more heavily in securities of U.S. government sponsored instrumentalities and in money market mutual funds that invest in those securities, which, in the absence of an exemptive order, are not affiliated with the Investment Adviser. Obligations of certain agencies and instrumentalities of the U.S. government, such as the Government National Mortgage

48

The Gabelli Convertible and Income Securities Fund Inc.

Additional Fund Information (Continued) (Unaudited)

Association, are supported by the “full faith and credit” of the U.S. government; others, such as those of the Export-Import Bank of the U.S., are supported by the right of the issuer to borrow from the U.S. Treasury; others, such as those of the Federal National Mortgage Association, are supported by the discretionary authority of the U.S. government to purchase the agency’s obligations; and still others, such as those of the Student Loan Marketing Association, are supported only by the credit of the instrumentality. No assurance can be given that the U.S. government would provide financial support to U.S. government sponsored instrumentalities if it is not obligated to do so by law. During temporary defensive periods, the Fund may be less likely to achieve its investment objective. See “Management of the Fund—General.”

Loans of Portfolio Securities. To increase income, the Fund may lend its portfolio securities to securities broker-dealers or financial institutions if the loan is collateralized in accordance with applicable regulatory requirements.

If the borrower fails to maintain the requisite amount of collateral, the loan automatically terminates and the Fund could use the collateral to replace the securities while holding the borrower liable for any excess of replacement cost over the value of the collateral. As with any extension of credit, there are risks of delay in recovery and in some cases even loss of rights in collateral should the borrower of the securities violate the terms of the loan or fail financially. There can be no assurance that borrowers will not fail financially. On termination of the loan, the borrower is required to return the securities to the Fund, and any gain or loss in the market price during the loan would inure to the Fund. If the other party to the loan petitions for bankruptcy or becomes subject to the United States Bankruptcy Code, the law regarding the rights of the Fund is unsettled. As a result, under extreme circumstances, there may be a restriction on the Fund’s ability to sell the collateral and the Fund would suffer a loss.

Warrants and Rights. The Fund may invest without limit in warrants or rights (other than those acquired in units or attached to other securities) that entitle the holder to buy equity securities at a specific price for a specific period of time but will do so only if such equity securities are deemed appropriate by the Investment Adviser for inclusion in the Fund’s portfolio.

RISK FACTORS AND SPECIAL CONSIDERATIONS

Investors should consider the following risk factors and special considerations associated with investing in the Fund:

General Risks

Market Risk. The market price of securities owned by the Fund may go up or down, sometimes rapidly or unpredictably. Securities may decline in value due to factors affecting securities markets generally or particular industries represented in the securities markets. The value of a security may decline due to general market conditions which are not specifically related to a particular company, such as real or perceived adverse economic conditions, changes in the general outlook for corporate earnings, changes in interest or currency rates, adverse changes to credit markets or adverse investor sentiment generally. The value of a security may also decline due to factors which affect a particular industry or industries, such as labor shortages or increased production costs and competitive conditions within an industry. During a general downturn in the securities markets, multiple asset classes may decline in value simultaneously. Equity securities generally have greater

49

The Gabelli Convertible and Income Securities Fund Inc.

Additional Fund Information (Continued) (Unaudited)

price volatility than fixed income securities. Credit ratings downgrades may also negatively affect securities held by the Fund. Even when markets perform well, there is no assurance that the investments held by the Fund will increase in value along with the broader market.

In addition, market risk includes the risk that geopolitical and other events will disrupt the economy on a national or global level. For instance, war, terrorism, market manipulation, government defaults, government shutdowns, political changes or diplomatic developments, public health emergencies (such as the spread of infectious diseases, pandemics and epidemics) and natural/environmental disasters can all negatively impact the securities markets, which could cause the Fund to lose value. These events could reduce consumer demand or economic output, result in market closures, travel restrictions or quarantines, and significantly adversely impact the economy. The current contentious domestic political environment, as well as political and diplomatic events within the United States and abroad, such as the U.S. government’s inability at times to agree on a long-term budget and deficit reduction plan, has in the past resulted, and may in the future result, in a government shutdown, which could have an adverse impact on the Fund’s investments and operations. Additional and/or prolonged U.S. federal government shutdowns may affect investor and consumer confidence and may adversely impact financial markets and the broader economy, perhaps suddenly and to a significant degree. Governmental and quasi-governmental authorities and regulators throughout the world have previously responded to serious economic disruptions with a variety of significant fiscal and monetary policy changes, including but not limited to, direct capital infusions into companies, new monetary programs and dramatically lower interest rates. An unexpected or sudden reversal of these policies, or the ineffectiveness of these policies, could increase volatility in securities markets, which could adversely affect the Fund’s investments. Any market disruptions could also prevent the Fund from executing advantageous investment decisions in a timely manner. To the extent that the Fund focuses its investments in a region enduring geopolitical market disruption, it will face higher risks of loss, although the increasing interconnectivity between global economies and financial markets can lead to events or conditions in one country, region or financial market adversely impacting a different country, region or financial market. Thus, investors should closely monitor current market conditions to determine whether the Fund meets their individual financial needs and tolerance for risk.

Exchanges and securities markets may close early, close late or issue trading halts on specific securities or generally, which may result in, among other things, the Fund being unable to buy or sell certain securities or financial instruments at an advantageous time or accurately price its portfolio investments.

Interest Rate Risk Generally. The primary risk associated with dividend-and interest-paying securities is interest rate risk. A decrease in interest rates will generally result in an increase in the investment value of such securities, while increases in interest rates will generally result in a decline in the investment value of such securities. This effect is generally more pronounced for fixed rate securities than for securities whose income rate is periodically reset.

General interest rate fluctuations may have a substantial negative impact on the Fund’s investments, the value of the Fund and the Fund’s rate of return. A reduction in the interest or dividend rates on new investments relative to interest or dividend rates on current investments could also have an adverse impact on the Fund’s net investment income. An increase in interest rates could decrease the value of any investments held by the Fund that earn fixed interest or dividend rates, including debt securities, convertible securities, preferred stocks, loans and high-yield bonds, and also could increase interest or dividend expenses, thereby decreasing net income.

The magnitude of these fluctuations in the market price of bonds and other income- or dividend-paying securities is generally greater for those securities with longer maturities. Fluctuations in the market price of the Fund’s investments will not affect interest income derived from instruments already owned by the Fund, but will be reflected in the Fund’s net asset value. The Fund may lose money if short-term or long-term interest rates rise sharply in a manner not anticipated by Fund management. To the extent the Fund invests in securities that may be prepaid at the option of the obligor, the sensitivity of such securities to changes in interest rates may increase (to the detriment of the Fund) when interest rates rise. Moreover, because rates on certain floating rate securities typically reset only periodically, changes in prevailing interest rates (and particularly sudden and significant changes) can be expected to cause some fluctuations in the net asset value of the Fund to the extent that it invests in floating rate securities. These basic principles of bond prices also apply to U.S. government securities. A security backed by the “full faith and credit” of the U.S. government is guaranteed only as to its stated interest rate and face value at maturity, not its current market price. Just like other income- or dividend-paying securities, government-guaranteed securities will fluctuate in value when interest rates change.

The Fund’s use of leverage will tend to increase the Fund’s interest rate risk. The Fund may invest in variable and floating rate instruments, which generally are less sensitive to interest rate changes than longer duration fixed rate instruments but may decline in value in response to rising interest rates if, for example, the rates at which they pay interest do not rise as much, or as quickly, as market interest rates in general. Conversely, variable and floating rate instruments generally will not increase in value if interest rates decline. The Fund also may invest in inverse floating rate securities, which may decrease in value if interest rates increase, and which also may exhibit greater price volatility than fixed rate obligations with similar credit quality. To the extent the Fund holds variable or floating rate instruments, a decrease (or, in the case of inverse floating rate securities, an increase) in market interest rates will adversely affect the income received from such securities, which may adversely affect the net asset value of the Fund’s common shares.

There is a risk that increased interest rates may cause the economy to enter a recession. Any such recession would negatively impact the Fund and the investments held by the Fund. These impacts may include:

| ● | severe declines in the Fund’s net asset values;

| ● | inability of the Fund to accurately or reliably value its portfolio;

| ● | inability of the Fund to pay any dividends or distributions;

| ● | inability of the Fund to maintain its status as a registered investment company (“RIC”) under the Internal Revenue Code of 1986, as amended (the “Code”);

| ● | declines in the value of the Fund’s investments;

| ● | increased risk of default or bankruptcy by the companies in which the Fund invests;

| ● | increased risk of companies in which the Fund invests being unable to weather an extended cessation of normal economic activity and thereby impairing their ability to continue functioning as a going concern; and

| ● | limited availability of new investment opportunities.

Inflation Risk. Inflation risk is the risk that the value of assets or income from investments will be worth less in the future as inflation decreases the value of money. Inflation rates may change frequently and significantly as a result of various factors, including unexpected shifts in the domestic or global economy and changes in

51

The Gabelli Convertible and Income Securities Fund Inc.

Additional Fund Information (Continued) (Unaudited)

economic policies, and the Fund’s investments may not keep pace with inflation, which may result in losses to Fund shareholders. As inflation increases, the real value of the Fund’s shares and dividends may decline. In addition, during any periods of rising inflation, interest rates of any debt securities held by the Fund would likely increase, which would tend to further reduce returns to shareholders. This risk is greater for fixed-income instruments with longer maturities.

Convertible Securities Risk. Convertible securities generally offer lower interest or dividend yields than non-convertible securities of similar quality. The market values of convertible securities tend to decline as interest rates increase and, conversely, to increase as interest rates decline. In the absence of adequate anti-dilution provisions in a convertible security, dilution in the value of the Fund’s holding may occur in the event the underlying stock is subdivided, additional equity securities are issued for below market value, a stock dividend is declared or the issuer enters into another type of corporate transaction that has a similar effect.

The value of a convertible security is influenced by the value of the underlying equity security. Convertible debt securities and preferred stocks may depreciate in value if the market value of the underlying equity security declines or if rates of interest increase. In addition, although debt securities are liabilities of a corporation which the corporation is generally obligated to repay at a specified time, debt securities, particularly convertible debt securities, are often subordinated to the claims of some or all of the other creditors of the corporation.

Mandatory conversion securities (securities that automatically convert into equity securities at a future date) may limit the potential for capital appreciation and, in some instances, are subject to complete loss of invested capital. Other innovative convertibles include “equity-linked” securities, which are securities or derivatives that may have fixed, variable, or no interest payments prior to maturity, may convert (at the option of the holder or on a mandatory basis) into cash or a combination of cash and common stock, and may be structured to limit the potential for capital appreciation. Equity-linked securities may be illiquid and difficult to value and may be subject to greater credit risk than that of other convertibles. Moreover, mandatory conversion securities and equity-linked securities have increased the sensitivity of the convertible securities market to the volatility of the equity markets and to the special risks of those innovations, which may include risks different from, and possibly greater than, those associated with traditional convertible securities.

Preferred stocks are equity securities in the sense that they do not represent a liability of the corporation. In the event of liquidation of the corporation, and after its creditors have been paid or provided for, holders of preferred stock are generally entitled to a preference as to the assets of the corporation before any distribution may be made to the holders of common stock. Debt securities normally do not have voting rights. Preferred stocks may have no voting rights or may have voting rights only under certain circumstances.

Credit Risk. Credit risk is the risk that an issuer will fail to pay interest or dividends and principal in a timely manner. Companies that issue convertible securities may be small to medium-size, and they often have low credit ratings. In addition, the credit rating of a company’s convertible securities is generally lower than that of its conventional debt securities. Convertible securities are normally considered “junior” securities—that is, the company usually must pay interest on its conventional debt before it can make payments on its convertible securities. Credit risk could be high for the Fund, because it could invest in securities with low credit quality. The lower a debt security is rated, the greater its default risk. As a result, the Fund may incur cost and delays in enforcing its rights against the issuer.

52

The Gabelli Convertible and Income Securities Fund Inc.

Market Risk. 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.

Interest Rate Risk for Convertible Securities. The securities are particularly sensitive to interest rate changes when their predetermined conversion price is much higher than the issuing company’s common stock.

Sector Risk. Sector risk is the risk that returns from the economic sectors in which convertible securities are concentrated will trail returns from other economic sectors. As a group, sectors tend to go through cycles of doing better-or-worse-than the convertible securities market in general. These periods have, in the past, lasted for as long as several years. Moreover, the sectors that dominate this market change over time.

Dilution Risk. In the absence of adequate anti-dilution provisions in a convertible security, dilution in the value of the Fund’s holding may occur in the event the underlying stock is subdivided, additional equity securities are issued for below market value, a stock dividend is declared, or the issuer enters into another type of corporate transaction that has a similar effect.

Fixed Income Securities Risks. Fixed income securities in which the Fund may invest are generally subject to the following risks:

| ● | Interest Rate Risk. The market value of bonds and other fixed-income or dividend paying securities changes in response to interest rate changes and other factors. Interest rate risk is the risk that prices of bonds and other income or dividend paying securities will increase as interest rates fall and decrease as interest rates rise. See “Risk Factors and Special Considerations—General Risks—Interest Rate Risks Generally.”

| ● | Credit Risk. Credit risk is the risk that one or more income or dividend paying securities in the Fund’s portfolio will decline in price or fail to pay interest/distributions or principal when due because the issuer of the security experiences a decline in its financial status. Credit risk is increased when a portfolio security is downgraded or the perceived creditworthiness of the issuer deteriorates. To the extent the Fund invests in below investment grade securities, it will be exposed to a greater amount of credit risk than a fund which only invests in investment grade securities. See “—Non-Investment Grade Securities.” In addition, to the extent the Fund uses credit derivatives, such use will expose it to additional risk in the event that the bonds underlying the derivatives default. The degree of credit risk depends on the issuer’s financial condition and on the terms of the securities.

| ● | Issuer Risk. Issuer risk is the risk that the value of an income or dividend paying security may decline for a number of reasons which directly relate to the issuer, such as management performance, financial leverage, reduced demand for the issuer’s goods and services, historical and prospective earnings of the issuer and the value of the assets of the issuer.

| ● | Prepayment Risk. Prepayment risk is the risk that during periods of declining interest rates, borrowers may exercise their option to prepay principal earlier than scheduled. For income or dividend paying

53

The Gabelli Convertible and Income Securities Fund Inc.

Additional Fund Information (Continued) (Unaudited)

|  | securities, such payments often occur during periods of declining interest rates, forcing the Fund to reinvest in lower yielding securities, resulting in a possible decline in the Fund’s income and distributions to shareholders. This is known as prepayment or “call” risk. Below investment grade securities frequently have call features that allow the issuer to redeem the security at dates prior to its stated maturity at a specified price (typically greater than par) only if certain prescribed conditions are met (“call protection”). For premium bonds (bonds acquired at prices that exceed their par or principal value) purchased by the Fund, prepayment risk may be enhanced.

| ● | Duration and Maturity Risk. The Fund has no set policy regarding portfolio maturity or duration of the fixed-income securities it may hold. The Investment Adviser may seek to adjust the duration or maturity of the Fund’s fixed-income holdings based on its assessment of current and projected market conditions and all other factors that the Investment Adviser deems relevant. In comparison to maturity (which is the date on which the issuer of a debt instrument is obligated to repay the principal amount), duration is a measure of the price volatility of a debt instrument as a result in changes in market rates of interest, based on the weighted average timing of the instrument’s expected principal and interest payments. Specifically, duration measures the anticipated percentage change in NAV that is expected for every percentage point change in interest rates. The two have an inverse relationship.

Duration can be a useful tool to estimate anticipated price changes to a fixed pool of income securities associated with changes in interest rates. For example, a duration of five years means that a 1% decrease in interest rates will increase the NAV of the portfolio by approximately 5%; if interest rates increase by 1%, the NAV will decrease by 5%. However, in a managed portfolio of fixed income securities having differing interest or dividend rates or payment schedules, maturities, redemption provisions, call or prepayment provisions and credit qualities, actual price changes in response to changes in interest rates may differ significantly from a duration-based estimate at any given time. Actual price movements experienced by a portfolio of fixed income securities will be affected by how interest rates move (i.e., changes in the relationship of long term interest rates to short term interest rates), the magnitude of any move in interest rates, actual and anticipated prepayments of principal through call or redemption features, the extension of maturities through restructuring, the sale of securities for portfolio management purposes, the reinvestment of proceeds from prepayments on and from sales of securities, and credit quality-related considerations whether associated with financing costs to lower credit quality borrowers or otherwise, as well as other factors. Accordingly, while duration maybe a useful tool to estimate potential price movements in relation to changes in interest rates, investors are cautioned that duration alone will not predict actual changes in the net asset or market value of the Fund’s shares and that actual price movements in the Fund’s portfolio may differ significantly from duration-based estimates.

Duration differs from maturity in that it takes into account a security’s yield, coupon payments and its principal payments in addition to the amount of time until the security matures. As the value of a security changes over time, so will its duration. Prices of securities with longer durations tend to be more sensitive to interest rate changes than securities with shorter durations. In general, a portfolio of securities with a longer duration can be expected to be more sensitive to interest rate changes than a portfolio with a shorter duration. Any decisions as to the targeted duration or maturity of any particular category of investments will be made based on all pertinent market factors at any given time. The Fund may incur

54

The Gabelli Convertible and Income Securities Fund Inc.

Additional Fund Information (Continued) (Unaudited)

costs in seeking to adjust the portfolio average duration or maturity. There can be no assurance that the Investment Adviser’s assessment of current and projected market conditions will be correct or that any strategy to adjust duration or maturity will be successful at any given time.

Corporate Bonds Risk. The market value of a corporate bond generally may be expected to rise and fall inversely with interest rates. The market value of intermediate and longer term corporate bonds is generally more sensitive to changes in interest rates than is the market value of shorter term corporate bonds. The market value of a corporate bond also may be affected by factors directly related to the issuer, such as investors’ perceptions of the creditworthiness of the issuer, the issuer’s financial performance, perceptions of the issuer in the market place, performance of management of the issuer, the issuer’s capital structure and use of financial leverage and demand for the issuer’s goods and services. Certain risks associated with investments in corporate bonds are described elsewhere in this Annual Report in further detail, including under “Risk Factors and Special Considerations—General Risks—Fixed Income Securities Risks—Credit Risk,” “—Fixed Income Securities Risks—Interest Rate Risk” and “—Fixed Income Securities Risks—Prepayment Risk.” There is a risk that the issuers of corporate bonds may not be able to meet their obligations on interest or principal payments at the time called for by an instrument. Corporate bonds of below investment grade quality are often high risk and have speculative characteristics and may be particularly susceptible to adverse issuer-specific developments. Corporate bonds of below investment grade quality are subject to the risks described herein under “—Non-Investment Grade Securities Risk.”

Non-Investment Grade Securities Risk. The Fund may invest in securities rated below investment grade by recognized rating agencies or unrated securities of comparable quality. The prices of these lower grade securities are more sensitive to negative developments, such as a decline in the issuer’s revenues or a general economic downturn, than are the prices of higher grade securities. Securities of below investment grade quality—those securities rated below “Baa” by Moody’s or below “BBB” by S&P (or unrated securities of comparable quality)—are predominantly speculative with respect to the issuer’s capacity to pay interest and repay principal when due and therefore involve a greater risk of default. Securities rated below investment grade commonly are referred to as “junk bonds” or “high yield” securities and generally pay a premium above the yields of U.S. government securities or securities of investment grade issuers because they are subject to greater risks than these securities. These risks, which reflect their speculative character, include the following:

| ● | greater volatility;

| ● | greater credit risk and risk of default;

| ● | potentially greater sensitivity to general economic or industry conditions;

| ● | potential lack of attractive resale opportunities (illiquidity); and

| ● | additional expenses to seek recovery from issuers who default.

In addition, the prices of these non-investment grade securities are more sensitive to negative developments, such as a decline in the issuer’s revenues or a general economic downturn, than are the prices of higher grade securities. Non-investment grade securities tend to be less liquid than investment grade securities. The market value of non-investment grade securities may be more volatile than the market value of investment grade securities and generally tends to reflect the market’s perception of the creditworthiness of the issuer and

55

The Gabelli Convertible and Income Securities Fund Inc.

Additional Fund Information (Continued) (Unaudited)

short term market developments to a greater extent than investment grade securities, which primarily reflect fluctuations in general levels of interest rates.

Ratings are relative and subjective and not absolute standards of quality. Securities ratings are based largely on the issuer’s historical financial condition and the rating agencies’ analysis at the time of rating. Consequently, the rating assigned to any particular security is not necessarily a reflection of the issuer’s current financial condition.

The Fund may purchase securities of companies that are experiencing significant financial or business difficulties, including companies involved in bankruptcy or other reorganization and liquidation proceedings. Although such investments may result in significant financial returns to the Fund, they involve a substantial degree of risk. The level of analytical sophistication, both financial and legal, necessary for successful investments in issuers experiencing significant business and financial difficulties is unusually high. There can be no assurance that the Fund will correctly evaluate the value of the assets collateralizing its investments or the prospects for a successful reorganization or similar action. In any reorganization or liquidation proceeding relating to a portfolio investment, the Fund may lose all or part of its investment or may be required to accept collateral with a value less than the amount of the Fund’s initial investment.

As a part of its investments in non-investment grade securities, the Fund may invest in the securities of issuers in default. The Fund invests in securities of issuers in default only when the Investment Adviser believes that such issuers will honor their obligations and emerge from bankruptcy protection and that the value of such issuers’ securities will appreciate. By investing in the securities of issuers in default, the Fund bears the risk that these issuers will not continue to honor their obligations or emerge from bankruptcy protection or that the value of these securities will not otherwise appreciate.

In addition to using statistical rating agencies and other sources, the Investment Adviser will also perform its own analysis of issuers in seeking investments that it believes to be underrated (and thus higher yielding) in light of the financial condition of the issuer. Its analysis of issuers may include, among other things, current and anticipated cash flow and borrowing requirements, value of assets in relation to historical cost, strength of management, responsiveness to business conditions, credit standing and current anticipated results of operations. In selecting investments for the Fund, the Investment Adviser may also consider general business conditions, anticipated changes in interest rates and the outlook for specific industries.

Subsequent to its purchase by the Fund, an issue of securities may cease to be rated or its rating may be reduced. In addition, it is possible that statistical rating agencies might change their ratings of a particular issue to reflect subsequent events on a timely basis. Moreover, such ratings do not assess the risk of a decline in market value. None of these events will require the sale of the securities by the Fund, although the Investment Adviser will consider these events in determining whether the Fund should continue to hold the securities.

Income securities, including non-investment grade securities and comparable unrated securities, frequently have call or buy-back features that permit their issuers to call or repurchase the securities from their holders, such as the Fund. If an issuer exercises these rights during periods of declining interest rates, the Fund may have to replace the security with a lower yielding security, thus resulting in a decreased return for the Fund.

The market for non-investment grade and comparable unrated securities has at various times, particularly during times of economic recession, experienced substantial reductions in market value and liquidity. Past recessions

56

The Gabelli Convertible and Income Securities Fund Inc.

Additional Fund Information (Continued) (Unaudited)

have adversely affected the value of such securities as well as the ability of certain issuers of such securities to repay principal and pay interest thereon or to refinance such securities. The market for those securities could react in a similar fashion in the event of any future economic recession.

Equity Risk. The principal risk of investing in equity securities is equity risk. Equity risk is the risk that the price of an equity security will fall due to general market and economic conditions, perceptions regarding the industry in which the issuer participates or the issuing company’s particular circumstances. Common stock in which the Fund will invest or receive upon conversion of convertible securities is subject to such equity risk. In the case of convertible securities, it is the conversion value of a convertible security that is subject to the equity risk; that is, if the appreciation potential of a convertible security is not realized, the premium paid for its conversion value may not be recovered. See “Investment Objective and Policies—Investment Practices—Convertible Securities.”

Common Stock Risk. Common stock of an issuer in the Fund’s portfolio may decline in price for a variety of reasons, including if the issuer fails to make anticipated dividend payments because the issuer of the security experiences a decline in its financial condition. Common stock in which the Fund invests is structurally subordinated as to income and residual value to preferred stock, bonds and other debt instruments in a company’s capital structure, in terms of priority to corporate income, and therefore will be subject to greater dividend risk than preferred stock or debt instruments of such issuers. In addition, while common stock has historically generated higher average returns than fixed income securities, common stock has also experienced significantly more volatility in generating those returns.

Distribution Risk for Equity Income Securities. In selecting equity income securities in which the Fund will invest, the Investment Adviser will consider the issuer’s history of making regular periodic distributions (i.e., dividends) to its equity holders. An issuer’s history of paying dividends, however, does not guarantee that the issuer will continue to pay dividends in the future. The dividend income stream associated with equity income securities generally is not guaranteed and will be subordinate to payment obligations of the issuer on its debt and other liabilities. Accordingly, in the event the issuer does not realize sufficient income in a particular period both to service its liabilities and to pay dividends on its equity securities, it may forgo paying dividends on its equity securities. In addition, because in most instances issuers are not obligated to make periodic distributions to the holders of their equity securities, such distributions or dividends generally may be discontinued at the issuer’s discretion.

Dividend-producing equity income securities, in particular those whose market price is closely related to their yield, may exhibit greater sensitivity to interest rate changes. See “—Fixed Income Securities Risks—Interest Rate Risk.” The Fund’s investments in dividend-producing equity income securities may also limit its potential for appreciation during a broad market advance.

The prices of dividend-producing equity income securities can be highly volatile. Investors should not assume that the Fund’s investments in these securities will necessarily reduce the volatility of the Fund’s net asset value or provide “protection,” compared to other types of equity income securities, when markets perform poorly.

Preferred Stock Risk. There are special risks associated with the Fund investing in preferred securities, including:

57

The Gabelli Convertible and Income Securities Fund Inc.

Additional Fund Information (Continued) (Unaudited)

Deferral. Preferred securities may include provisions that permit the issuer, at its discretion, to defer distributions for a stated period without any adverse consequences to the issuer. If the Fund owns a preferred security on which distributions are being deferred by the issuer, the Fund may be required to report income for tax purposes although it has not yet received such deferred distributions.

Non-Cumulative Dividends. Some preferred stocks are non-cumulative, meaning that the dividends do not accumulate and need not ever be paid. A portion of the portfolio may include investments in non-cumulative preferred securities, whereby the issuer does not have an obligation to make up any arrearages to its shareholders. Should an issuer of a non-cumulative preferred stock held by the Fund determine not to pay dividends on such stock, the Fund’s return from that security may be adversely affected. There is no assurance that dividends or distributions on non-cumulative preferred stocks in which the Fund invests will be declared or otherwise made payable.

Subordination. Preferred securities are subordinated to bonds and other debt instruments in a company’s capital structure in terms of priority to corporate income and liquidation payments, and therefore will be subject to greater credit risk than more senior debt security instruments.

Liquidity. Preferred securities may be substantially less liquid than many other securities, such as common stocks or U.S. Government securities.

Limited Voting Rights. Generally, preferred security holders (such as the Fund) have no voting rights with respect to the issuing company unless preferred dividends have been in arrears for a specified number of periods, at which time the preferred security holders may be entitled to elect a number of directors to the issuer’s board. Generally, once all the arrearages have been paid, the preferred security holders no longer have voting rights.

Special Redemption Rights. In certain varying circumstances, an issuer of preferred securities may redeem the securities prior to a specified date. For instance, for certain types of preferred securities, a redemption may be triggered by a change in federal income tax or securities laws. As with call provisions, a redemption by the issuer may negatively impact the return of the security held by the Fund.

Computer Software/Services Companies Risk. Computer software/services companies can be significantly affected by competitive pressures, aggressive pricing, technological developments, changing domestic demand, the ability to attract and retain skilled employees and availability and price of components. The market for products produced by computer software/services companies is characterized by rapidly changing technology, rapid product obsolescence, cyclical market patterns, evolving industry standards and frequent new product introductions. The success of computer software/services companies depends in substantial part on the timely and successful introduction of new products and the ability to service such products. An unexpected change in one or more of the technologies affecting an issuer’s products or in the market for products based on a particular technology could have a material adverse effect on a participant’s operating results.

Many computer software/services companies rely on a combination of patents, copyrights, trademarks and trade secret laws to establish and protect their proprietary rights in their products and technologies. There can be no assurance that the steps taken by computer software/services companies to protect their proprietary rights will be adequate to prevent misappropriation of their technology or that competitors will not independently develop technologies that are substantially equivalent or superior to such companies’ technology.

U.S. Government Securities and Credit Rating Downgrade Risk. The Fund may invest in direct obligations of the government of the United States or its agencies. Obligations issued or guaranteed by the U.S. government, its agencies, authorities and instrumentalities and backed by the full faith and credit of the U.S. guarantee only that principal and interest will be timely paid to holders of the securities. These entities do not guarantee that the value of such obligations will increase, and, in fact, the market values of such obligations may fluctuate. In addition, not all U.S. government securities are backed by the full faith and credit of the United States; some are the obligation solely of the entity through which they are issued. There is no guarantee that the U.S. government would provide financial support to its agencies and instrumentalities if not required to do so by law.

In 2011, S&P lowered its long term sovereign credit rating on the U.S. to “AA+” from “AAA.” The downgrade by S&P increased volatility in both stock and bond markets, resulting in higher interest rates and higher Treasury yields, and increased the costs of all kinds of debt. On August 1, 2023, Fitch Ratings lowered its long-term sovereign credit rating on the U.S. to “AA+” from “AAA.” This and any further downgrades of U.S. credit ratings could have significant adverse effects on the U.S. economy generally and could result in significant adverse impacts on issuers of securities held by the Fund itself. The Investment Adviser cannot predict the effects of similar events in the future on the U.S. economy and securities markets or on the Fund’s portfolio. The Investment Adviser monitors developments and seeks to manage the Fund’s portfolio in a manner consistent with achieving the Fund’s investment objective, but there can be no assurance that it will be successful in doing so and the Investment Adviser may not timely anticipate or manage existing, new or additional risks, contingencies or developments.

Significant Holdings Risk. The Fund may invest up to 25% of its total assets in securities of a single industry; however, the Fund does not currently focus and has no current intent to focus on any particular industry or sector. In the event the Fund should choose to take significant positions in any particular industry or sector, the net asset value of the Fund will be more susceptible to factors affecting those particular types of companies, which, depending on the particular industry, may include, among others: governmental regulation; inflation; cost increases in raw materials, fuel and other operating expenses; technological innovations that may render existing products and equipment obsolete; and increasing interest rates resulting in high interest costs on borrowings needed for capital investment, including costs associated with compliance with environmental and other regulations. In such circumstances the Fund’s investments may be subject to greater risk and market fluctuation than a fund that had securities representing a broader range of industries.

Value Investing Risk. The Fund focuses its investments on the securities of companies that the Investment Adviser believes are undervalued or inexpensive relative to other investments. These types of securities may present risks in addition to the general risks associated with investing in common and preferred stocks. These securities generally are selected on the basis of an issuer’s fundamentals relative to current market price. Such securities are subject to the risk of mis-estimation of certain fundamental factors. In addition, during certain time periods market dynamics may strongly favor “growth” stocks of issuers that do not display strong fundamentals relative to market price based upon positive price momentum and other factors. Disciplined adherence to a “value” investment mandate during such periods can result in significant underperformance relative to overall market indices and other managed investment vehicles that pursue growth style investments and/or flexible equity style mandates.

59

Selection Risk. Different types of stocks tend to shift into and out of favor with stock market investors, depending on market and economic conditions. The performance of funds that invest in value-style stocks may at times be better or worse than the performance of stock funds that focus on other types of stocks or that have a broader investment style.

Merger Arbitrage Risk. The Fund may invest in securities of companies for which a tender or exchange offer has been made or announced, and in securities of companies for which a merger, consolidation, liquidation or reorganization proposal has been announced. The principal risk of such investments is that certain of such proposed transactions may be renegotiated, terminated or involve a longer time frame than originally contemplated, in which case the Fund may realize losses. Such risk is sometimes referred to as “merger arbitrage risk.” Among the factors that affect the level of risk with respect to the completion of the transaction are the deal spread and number of bidders, the friendliness of the buyer and seller, the strategic rationale behind the transaction, the existence of regulatory hurdles, the level of due diligence completed on the target company and the ability of the buyer to finance the transaction. If the spread between the purchase price and the current price of the seller’s stock is small, the risk that the transaction will not be completed may outweigh the potential return. If there is very little interest by other potential buyers in the target company, the risk of loss may be higher than where there are back-up buyers that would allow the arbitrageur to realize a similar return if the current deal falls through. Unfriendly management of the target company or change in friendly management in the middle of a deal increases the risk that the deal will not be completed even if the target company’s board has approved the transaction and may involve the risk of litigation expense if the target company pursues litigation in an attempt to prevent the deal from occurring. The underlying strategy behind the deal is also a risk consideration because the less a target company will benefit from a merger or acquisition, the greater the risk. There is also a risk that an acquiring company may back out of an announced deal if, in the process of completing its due diligence of the target company, it discovers something undesirable about such company. In addition, merger transactions are also subject to regulatory risk because a merger transaction often must be approved by a regulatory body or pass governmental antitrust review. All of these factors affect the timing and likelihood that the transaction will close. Even if the Investment Adviser selects announced deals with the goal of mitigating the risks that the transaction will fail to close, such risks may still delay the closing of such transaction to a date later than the Fund originally anticipated, reducing the level of desired return to the Fund.

Merger arbitrage positions are also subject to the risk of overall market movements. To the extent that a general increase or decline in equity values affects the stocks involved in a merger arbitrage position differently, the position may be exposed to loss.

Finally, merger arbitrage strategies depend for success on the overall volume of global merger activity, which has historically been cyclical in nature. During periods when merger activity is low, it may be difficult or impossible to identify opportunities for profit or to identify a sufficient number of such opportunities to provide balance among potential merger transactions. To the extent that the number of announced deals and corporate reorganizations decreases or the number of investors in such transactions increases, it is possible that merger arbitrage spreads will tighten, causing the profitability of investing in such transactions to diminish, which will in turn decrease the returns to the Fund from such investment activity.

Foreign Securities Risk. Investments in the securities of foreign issuers involve certain considerations and risks not ordinarily associated with investments in securities of domestic issuers and such securities may be

60

The Gabelli Convertible and Income Securities Fund Inc.

Additional Fund Information (Continued) (Unaudited)

more volatile than those of issuers located in the United States. Foreign companies are not generally subject to uniform accounting, auditing and financial standards and requirements comparable to those applicable to U.S. companies. Foreign securities exchanges, brokers and listed companies may be subject to less government supervision and regulation than exists in the United States. Dividend and interest income may be subject to withholding and other foreign taxes, which may adversely affect the net return on such investments. There may be difficulty in obtaining or enforcing a court judgment abroad. In addition, it may be difficult to effect repatriation of capital invested in certain countries. In addition, with respect to certain countries, there are risks of expropriation, confiscatory taxation, political or social instability or diplomatic developments that could affect assets of the Fund held in foreign countries. Dividend income the Fund receives from foreign securities may not be eligible for the special tax treatment applicable to qualified dividend income. Moreover, certain equity investments in foreign issuers classified as passive foreign investment companies may be subject to additional taxation risk.

There may be less publicly available information about a foreign company than a U.S. company. Foreign securities markets may have substantially less volume than U.S. securities markets and some foreign company securities are less liquid than securities of otherwise comparable U.S. companies. A portfolio of foreign securities may also be adversely affected by fluctuations in the rates of exchange between the currencies of different nations and by exchange control regulations. Foreign markets also have different clearance and settlement procedures that could cause the Fund to encounter difficulties in purchasing and selling securities on such markets and may result in the Fund missing attractive investment opportunities or experiencing loss. In addition, a portfolio that includes foreign securities can expect to have a higher expense ratio because of the increased transaction costs on non-U.S. securities markets and the increased costs of maintaining the custody of foreign securities.

Investments in foreign securities will expose the Fund to the direct or indirect consequences of political, social or economic changes in the countries that issue the securities or in which the issuers are located. Certain countries in which the Fund may invest have historically experienced, and may continue to experience, high rates of inflation, high interest rates, exchange rate fluctuations, large amounts of external debt, balance of payments and trade difficulties and extreme poverty and unemployment. Many of these countries are also characterized by political uncertainty and instability. The cost of servicing external debt will generally be adversely affected by rising international interest rates because many external debt obligations bear interest at rates which are adjusted based upon international interest rates.

The Fund also may purchase ADRs or U.S. dollar-denominated securities of foreign issuers. ADRs are receipts issued by U.S. banks or trust companies in respect of securities of foreign issuers held on deposit for use in the U.S. securities markets. While ADRs may not necessarily be denominated in the same currency as the securities into which they may be converted, many of the risks associated with foreign securities may also apply to ADRs. In addition, the underlying issuers of certain depositary receipts, particularly unsponsored or unregistered depositary receipts, are under no obligation to distribute shareholder communications to the holders of such receipts, or to pass through to them any voting rights with respect to the deposited securities.

The following provides more detail on certain pronounced risks with foreign investing:

Certain non-U.S. currencies, primarily in developing countries, have been devalued in the past and might face devaluation in the future. Currency devaluations generally have a significant and adverse impact on the devaluing

61

The Gabelli Convertible and Income Securities Fund Inc.

Additional Fund Information (Continued) (Unaudited)

country’s economy in the short and intermediate term and on the financial condition and results of companies’ operations in that country. Currency devaluations may also be accompanied by significant declines in the values and liquidity of equity and debt securities of affected governmental and private sector entities generally. To the extent that affected companies have obligations denominated in currencies other than the devalued currency, those companies may also have difficulty in meeting those obligations under such circumstances, which in turn could have an adverse effect upon the value of the Fund’s investments in such companies. There can be no assurance that current or future developments with respect to foreign currency devaluations will not impair the Fund’s investment flexibility, its ability to achieve its investment objective or the value of certain of its foreign currency-denominated investments.

Tax Consequences of Foreign Investing. The Fund’s transactions in foreign currencies, foreign currency-denominated debt obligations and certain foreign currency options, futures contracts and forward contracts (and similar instruments) may give rise to ordinary income or loss to the extent such income or loss results from fluctuations in the value of the foreign currency concerned. This treatment could increase or decrease the Fund’s ordinary income distributions to you, and may cause some or all of the Fund’s previously distributed income to be classified as a return of capital. In certain cases, the Fund may make an election to treat gain or loss attributable to certain investments as capital gain or loss.

EMU and Redenomination Risk. As the European debt crisis progressed, the possibility of one or more Eurozone countries exiting the European Monetary Union (“EMU”), or even the collapse of the Euro as a common currency arose, creating significant volatility at times in currency and financial markets. The effects of the collapse of the Euro or of the exit of one or more countries from the EMU, on the U.S. and global economies and securities markets are impossible to predict, and any such events could have a significant adverse impact on the value and risk profile of the Fund’s portfolio. Any partial or complete dissolution of the EMU could have significant adverse effects on currency and financial markets, and on the values of the Fund’s portfolio investments. If one or more EMU countries were to stop using the Euro as its primary currency, the Fund’s investments in such countries may be redenominated into a different or newly adopted currency. As a result, the value of those investments could decline significantly and unpredictably. In addition, securities or other investments that are redenominated may be subject to foreign currency risk, liquidity risk and valuation risk to a greater extent than similar investments currently denominated in Euros. To the extent a currency used for redenomination purposes is not specified in respect of certain EMU-related investments, or should the Euro cease to be used entirely, the currency in which such investments are denominated may be unclear, making such investments particularly difficult to value or dispose of. The Fund may incur additional expenses to the extent it is required to seek judicial or other clarification of the denomination or value of such securities.

Emerging Markets Risk. The considerations noted above in “Foreign Securities Risk” are generally intensified for investments in emerging market countries, including countries that may be considered “frontier” markets. Emerging market countries typically have economic and political systems that are less fully developed, and can be expected to be less stable than those of more developed countries. Investing in securities of companies in emerging markets may entail special risks relating to potential political and economic instability and the risks of expropriation, nationalization, confiscation or the imposition of restrictions on foreign investment, the lack of hedging instruments and restrictions on repatriation of capital invested. Economies of such countries can be subject to rapid and unpredictable rates of inflation or deflation. Emerging securities markets are substantially

62

The Gabelli Convertible and Income Securities Fund Inc.

Additional Fund Information (Continued) (Unaudited)

smaller, less developed, less liquid and more volatile than the major securities markets. The limited size of emerging securities markets and limited trading volume compared to the volume of trading in U.S. securities could cause prices to be erratic for reasons apart from factors that affect the quality of the securities. For example, limited market size may cause prices to be unduly influenced by traders who control large positions. Adverse publicity and investors’ perceptions, whether or not based on fundamental analysis, may decrease the value and liquidity of portfolio securities, especially in these markets. Other risks include high concentration of market capitalization and trading volume in a small number of issuers representing a limited number of industries, as well as a high concentration of investors and financial intermediaries; overdependence on exports, including gold and natural resources exports, making these economies vulnerable to changes in commodity prices; overburdened infrastructure and obsolete or unseasoned financial systems; environmental problems; less developed legal systems; and less reliable securities custodial services and settlement practices. Certain emerging markets may also face other significant internal or external risks, including the risk of war and civil unrest. For all of these reasons, investments in emerging markets may be considered speculative.

Eurozone Risk. A number of countries in the EU have experienced, and may continue to experience, severe economic and financial difficulties, increasing the risk of investing in the European markets. In particular, many EU nations are susceptible to economic risks associated with high levels of debt, notably due to investments in sovereign debt of countries such as Greece, Italy, Spain, Portugal, and Ireland. As a result, financial markets in the EU have been subject to increased volatility and declines in asset values and liquidity. Responses to these financial problems by European governments, central banks, and others, including austerity measures and reforms, may not work, may result in social unrest, and may limit future growth and economic recovery or have other unintended consequences. Further defaults or restructurings by governments and others of their debt could have additional adverse effects on economies, financial markets, and asset valuations around the world. Greece, Ireland, and Portugal have already received one or more “bailouts” from other Eurozone member states, and it is unclear how much additional funding they will require or if additional Eurozone member states will require bailouts in the future. One or more other countries may also abandon the euro and/or withdraw from the EU, placing its currency and banking system in jeopardy. The impact of these actions, especially if they occur in a disorderly fashion, is not clear, but could be significant and far-reaching.

Brexit Risk. The United Kingdom ceased to be a member of the European Union (the “EU”) on January 31, 2020 (“Brexit”). A Trade and Cooperation Agreement between the EU and the United Kingdom (the “TCA”) took effect on May 1, 2021, and now governs the relationship between the EU and the United Kingdom. While the TCA regulates a number of important areas, significant parts of the United Kingdom economy are not addressed in detail by the TCA, including in particular the services sector, which represents the largest component of the United Kingdom’s economy. As such, there remains uncertainty as to the scope, nature and terms of the relationship between the United Kingdom and the EU and the effect and implications of the TCA. Brexit may have a negative impact on the economy and currency of the United Kingdom and EU as a result of anticipated, perceived or actual changes to the United Kingdom’s economic and political relations with the EU. Brexit may also have a destabilizing impact on the EU to the extent other member states similarly seek to withdraw from the union. Any further exits of member states from the EU, or the possibility of such exits, would likely cause additional market disruption globally and introduce new legal and regulatory uncertainties. Any or all of these challenges may affect the value of the Fund’s investments that are economically tied to the United Kingdom or the EU, and could have an adverse impact on the Fund’s performance.

Smaller Companies Investment Risk. The Fund may invest in the securities of smaller, less seasoned companies. Smaller companies offer investment opportunities and additional risks. They may not be well known to the investing public, may not be significantly owned by institutional investors and may not have steady earnings growth. These companies may have limited product lines and markets, as well as shorter operating histories, less experienced management and more limited financial resources than larger companies. In addition, the securities of such companies may be more vulnerable to adverse general market or economic developments, more volatile in price, have wider spreads between their bid and ask prices and have significantly lower trading volumes than the securities of larger capitalization companies. As such, securities of these smaller companies may be less liquid than those of larger companies, and may experience greater price fluctuations than larger companies. In addition, small-cap or mid-cap company securities may not be widely followed by investors, which may result in reduced demand.

As a result, the purchase or sale of more than a limited number of shares of the securities of a smaller company may affect its market price. The Investment Adviser may need a considerable amount of time to purchase or sell its positions in these securities, particularly when other Investment Adviser-managed accounts or other investors are also seeking to purchase or sell them.

The securities of smaller capitalization companies generally trade in lower volumes and are subject to greater and more unpredictable price changes than larger capitalization securities or the market as a whole. In addition, smaller capitalization securities may be particularly sensitive to changes in interest rates, borrowing costs and earnings. Investing in smaller capitalization securities requires a longer-term view.

Securities of emerging companies may lack an active secondary market and may be subject to more abrupt or erratic price movements than securities of larger, more established companies or stock market averages in general. Competitors of certain companies, which may or may not be in the same industry, may have substantially greater financial resources than the companies in which the Fund may invest.

Investment Companies. The Fund may invest in the securities of other investment companies to the extent permitted by law. To the extent the Fund invests in the common equity of investment companies, the Fund will bear its ratable share of any such investment company’s expenses, including management fees. The Fund will also remain obligated to pay management fees to the Investment Adviser with respect to the assets invested in the securities of other investment companies. In these circumstances holders of the Fund’s common shares will be subject to duplicative investment expenses. The Fund will not purchase the securities of affiliated investment companies.

Prepayment Risks on Government Sponsored Mortgage-Backed Securities. The yield and maturity characteristics of government sponsored mortgage-backed securities differ from traditional debt securities. A

64

The Gabelli Convertible and Income Securities Fund Inc.

Additional Fund Information (Continued) (Unaudited)

major difference is that the principal amount of the obligations may generally be prepaid at any time because the underlying assets (i.e., loans) generally may be prepaid at any time. Prepayment risks include the following:

| ● | mortgage-backed securities less potential for growth in value than conventional bonds with comparable maturities;

| ● | in addition, when interest rates fall, the rate of prepayments tends to increase. During such periods, the reinvestment of prepayment proceeds by the Fund will generally be at lower rates than the rates that were carried by the obligations that have been prepaid;

| ● | because of these and other reasons, a government sponsored mortgage-backed security’s total return and maturity may be difficult to predict; and

| ● | to the extent that the Fund purchases government sponsored mortgage-backed securities at a premium, prepayments may result in loss of the Fund’s principal investment to the extent of premium paid.

Restricted and Illiquid Securities. Unregistered securities are securities that cannot be sold publicly in the United States without registration under the Securities Act. An illiquid investment is a security or other investment that cannot be disposed of within seven days in the ordinary course of business at approximately the value at which the Fund has valued the investment. Unregistered securities often can be resold only in privately negotiated transactions with a limited number of purchasers or in a public offering registered under the Securities Act. Considerable delay could be encountered in either event and, unless otherwise contractually provided for, the Fund’s proceeds upon sale may be reduced by the costs of registration or underwriting discounts. The difficulties and delays associated with such transactions could result in the Fund’s inability to realize a favorable price upon disposition of unregistered securities, and at times might make disposition of such securities impossible. The Fund may be unable to sell illiquid investments when it desires to do so, resulting in the Fund obtaining a lower price or being required to retain the investment. Illiquid investments generally must be valued at fair value, which is inherently less precise than utilizing market values for liquid investments, and may lead to differences between the price at which a security is valued for determining the Fund’s net asset value and the price the Fund actually receives upon sale.

Long-Term Objective; Not a Complete Investment Program. The Fund is intended for investors seeking a high level of total return over the long term. The Fund is not meant to provide a vehicle for those who wish to play short-term swings in the stock market. An investment in shares of the Fund should not be considered a complete investment program. Each shareholder should take into account the Fund’s investment objective as well as the shareholder’s other investments when considering an investment in the Fund.

Management Risk. The Fund is subject to management risk because it is an actively managed portfolio. The Investment Adviser will apply investment techniques and risk analyses in making investment decisions for the Fund, but there can be no guarantee that these will produce the desired results.

Dependence on Key Personnel. The Investment Adviser is dependent upon the expertise of Mr. Mario J. Gabelli in providing advisory services with respect to the Fund’s investments. If the Investment Adviser were to lose the services of Mr. Gabelli, its ability to service the Fund could be adversely affected. There can be no assurance that a suitable replacement could be found for Mr. Gabelli in the event of his death, resignation, retirement or inability to act on behalf of the Investment Adviser.

Market Disruption and Geopolitical Risk. General occurrence of events similar to those in recent years, such as localized wars, instability, new and ongoing pandemics, epidemics or outbreaks of infectious diseases in certain parts of the world, natural/environmental disasters in certain parts of the world, terrorist attacks in the United States and around the world, trade or tariff arrangements, social and political discord, debt crises, sovereign debt downgrades, increasingly strained relations between the United States and a number of foreign countries, including traditional allies, historical adversaries and the international community generally, new and continued political unrest in various countries, the exit or potential exit of one or more countries from the EU or the Economic and Monetary Union, continued changes in the balance of political power among and within the branches of the U.S. government, and government shutdowns, among others, may result in market volatility, may have long-term effects on the United States and worldwide financial markets, and may cause further economic uncertainties in the United States and worldwide.

The consequences of the conflicts between Russia and Ukraine and between Israel and Hamas, including international sanctions, the potential impact on inflation and increased disruption to supply chains may impact our portfolio companies, result in an economic downturn or recession either globally or locally in the U.S. or other economies, reduce business activity, spawn additional conflicts (whether in the form of traditional military action, reignited “cold” wars or in the form a virtual warfare such as cyberattacks) with similar and perhaps wider ranging impacts and consequences and have an adverse impact on the Fund’s returns and net asset value. The current contentious domestic political environment, as well as political and diplomatic events within the United States and abroad, such as the U.S. government’s inability at times to agree on a long-term budget and deficit reduction plan, may in the future result in additional government shutdowns, which could have a material adverse effect on the Funds’ investments and operations. In addition, the Funds’ ability to raise additional capital in the future through the sale of securities could be materially affected by a government shutdown. Additional and/or prolonged U.S. government shutdowns may affect investor and consumer confidence and may adversely impact financial markets and the broader economy, perhaps suddenly and to a significant degree.

Uncertainty and periods of volatility still remain, and risks to a robust resumption of growth persist. Federal Reserve policy, including with respect to certain interest rates, may adversely affect the value, volatility and liquidity of dividend and interest paying securities. Market volatility, dramatic changes to interest rates and/or a return to unfavorable economic conditions may lower the Fund’s performance or impair the Fund’s ability to achieve its investment objective.

The occurrence of any of the above events could have a significant adverse impact on the value and risk profile of the Fund’s portfolio. It is not known how long the securities markets may be affected by similar events, and the effects of similar events in the future on the U.S. economy and securities markets cannot be predicted. There can be no assurance that similar events and other market disruptions will not have other material and adverse implications.

The rules dealing with U.S. federal income taxation are constantly under review by persons involved in the legislative process and by the IRS and the U.S. Treasury Department. The effect of any changes to the Code on the value of our assets or the Fund’s common shares or market conditions generally is uncertain.

Regulation and Government Intervention Risk. Changes enacted by the current or future presidential administration could significantly impact the regulation of financial markets in the U.S. Areas subject to potential

66

The Gabelli Convertible and Income Securities Fund Inc.

Additional Fund Information (Continued) (Unaudited)

change, amendment or repeal include trade and foreign policy, corporate tax rates, energy and infrastructure policies, the environment and sustainability, criminal and social justice initiatives, immigration, healthcare and the oversight of certain federal financial regulatory agencies and the Federal Reserve. Certain of these changes can, and have, been effectuated through executive order. It is not possible to predict what, if any, actions will be taken or, if taken, their effect on the economy, securities markets or the financial stability of the U.S. The Fund may be affected by governmental action in ways that are not foreseeable, and there is a possibility that such actions could have a significant adverse effect on the Fund and the Fund’s ability to achieve its investment objectives.

Additional risks arising from the differences in expressed policy preferences among the various constituencies in the branches of the U.S. government has led in the past, and may lead in the future, to short-term or prolonged policy impasses, which could, and has, resulted in shutdowns of the U.S. federal government. U.S. federal government shutdowns, especially prolonged shutdowns, could have a significant adverse impact on the economy in general and could impair the ability of issuers to raise capital in the securities markets. Any of these effects could have a material adverse effect on the Fund’s net asset value.

In addition, the rules dealing with the U.S. federal income taxation are constantly under review by persons involved in the legislative process and by the IRS and the U.S. Treasury Department. The effect of any changes to the Code is uncertain, both in terms of the direct effect on the taxation of an investment in the Fund’s shares and their indirect effect on the value of the Fund’s assets, Fund shares or market conditions generally.

In addition, the U.S. government has proposed and adopted multiple regulations that could have a long-lasting impact on the Fund and on the closed-end fund industry in general. The SEC’s final rules and amendments that modernize reporting and disclosure, along with other potential upcoming regulations, could, among other things, restrict the Fund’s ability to engage in transactions, and/or increase overall expenses of the Fund.

The Fund may be affected by governmental action in ways that are not foreseeable, and there is a possibility that such actions could have a significant adverse effect on the Fund and its ability to achieve its investment objective.

Deflation Risk. Deflation risk is the risk that prices throughout the economy decline over time, which may have an adverse effect on the market valuation of companies, their assets and their revenues. In addition, deflation may have an adverse effect on the creditworthiness of issuers and may make issuer default more likely, which may result in a decline in the value of the Fund’s portfolio.

Loans of Portfolio Securities. Consistent with applicable regulatory requirements and the Fund’s investment restrictions, the Fund may lend its portfolio securities to securities broker-dealers or financial institutions, provided that such loans are callable at any time by the Fund (subject to notice provisions), and are at all times collateralized in accordance with applicable regulatory requirements. The advantage of such loans is that the Fund continues to receive the income on the loaned securities while at the same time earning interest on the cash amounts deposited as collateral, which will be invested in short term obligations. The Fund will not lend its portfolio securities if such loans are not permitted by the laws or regulations of any state in which its shares are qualified for sale.

67

The Gabelli Convertible and Income Securities Fund Inc.

Additional Fund Information (Continued) (Unaudited)

Portfolio Turnover Risk. The Fund’s annual portfolio turnover rate may vary greatly from year to year, as well as within a given year. Portfolio turnover rate is not considered a limiting factor in the execution of investment decisions for the Fund. A higher portfolio turnover rate results in correspondingly greater brokerage commissions and other transactional expenses that are borne by the Fund. High portfolio turnover may result in an increased realization of net short term capital gains by the Fund which, when distributed to common shareholders, will be taxable as ordinary income. Additionally, in a declining market, portfolio turnover may create realized capital losses. For the fiscal years ended September 30, 2024 and September 30, 2025, the portfolio turnover rate of the Fund was 77% and 94%, respectively. The Fund anticipates that its portfolio turnover rate will generally not exceed 100%.

Legal, Tax and Regulatory Risks. Legal, tax and regulatory changes could occur that may have material adverse effects on the Fund. For example, the regulatory and tax environment for derivative instruments in which the Fund may participate is evolving, and such changes in the regulation or taxation of derivative instruments may have material adverse effects on the value of derivative instruments held by the Fund and the ability of the Fund to pursue its investment strategies. Changes to the U.S. federal tax laws and interpretations thereof could adversely affect an investment in the Fund.

We cannot assure you what percentage of the distributions paid on the Fund’s shares, if any, will consist of tax-advantaged qualified dividend income or long-term capital gains or what the tax rates on various types of income will be in future years.

To qualify for the favorable U.S. federal income tax treatment generally accorded to RICs under the Code, the Fund must, among other things, derive in each taxable year at least 90% of its gross income from certain prescribed sources and distribute for each taxable year at least 90% of its “investment company taxable income.” Statutory limitations on distributions on the common shares if the Fund fails to satisfy the 1940 Act’s asset coverage requirements could jeopardize the Fund’s ability to meet such distribution requirements. While the Fund presently intends to purchase or redeem notes or preferred shares, if any, to the extent necessary in order to maintain compliance with such asset coverage requirements, there can be no assurance that such actions can be effected in time to meet the Code requirements. If for any taxable year the Fund does not qualify as a RIC, all of its taxable income for that year (including its net capital gain) would be subject to tax at regular corporate rates without any deduction for distributions to shareholders, and such distributions would be taxable as ordinary dividends to the extent of the Fund’s current and accumulated earnings and profits.

SOFR Risk. As of June 30, 2023, overnight and 12-month US dollar LIBOR settings permanently ceased. 1-, 3-, and 6-month U.S. dollar LIBOR settings ceased to be published as of September 2024. As an alternative to LIBOR, the Financial Reporting Council, in conjunction with the Alternative Reference Rates Committee, a steering committee comprised of large U.S. financial institutions, recommended replacing U.S. dollar LIBOR with the Secured Overnight Financing Rate (“SOFR”), a new index calculated by reference to short-term repurchase agreements, backed by Treasury securities.

SOFR is intended to be a broad measure of the cost of borrowing funds overnight in transactions that are collateralized by U.S. Treasury securities. SOFR is calculated based on transaction-level data collected from various sources. For each trading day, SOFR is calculated as a volume-weighted median rate derived from such data. SOFR is calculated and published by the Federal Reserve Bank of New York (“FRBNY”). If data from

68

The Gabelli Convertible and Income Securities Fund Inc.

Additional Fund Information (Continued) (Unaudited)

a given source required by the FRBNY to calculate SOFR is unavailable for any day, then the most recently available data for that segment will be used, with certain adjustments. If errors are discovered in the transaction data or the calculations underlying SOFR after its initial publication on a given day, SOFR may be republished at a later time that day. Rate revisions will be effected only on the day of initial publication and will be republished only if the change in the rate exceeds one basis point.

Because SOFR is a financing rate based on overnight secured funding transactions, it differs fundamentally from LIBOR. LIBOR was intended to be an unsecured rate that represents interbank funding costs for different short-term maturities or tenors. It was a forward-looking rate reflecting expectations regarding interest rates for the applicable tenor. Thus, LIBOR was intended to be sensitive, in certain respects, to bank credit risk and to term interest rate risk. In contrast, SOFR is a secured overnight rate reflecting the credit of U.S. Treasury securities as collateral. Thus, it is largely insensitive to credit-risk considerations and to short-term interest rate risks. SOFR is a transaction-based rate, and it has been more volatile than other benchmark or market rates during certain periods. For these reasons, among others, there is no assurance that SOFR, or rates derived from SOFR, will perform in the same or similar way as LIBOR would have performed at any time, and there is no assurance that SOFR-based rates will be a suitable substitute for LIBOR. SOFR has a limited history, having been first published in April 2018. The future performance of SOFR, and SOFR-based reference rates, cannot be predicted based on SOFR’s history or otherwise. Levels of SOFR in the future may bear little or no relation to historical levels of SOFR, LIBOR or other rates.

Legislation Risk. At any time after the date of this Annual Report, legislation may be enacted that could negatively affect the assets of the Fund. Legislation or regulation may change the way in which the Fund itself is regulated. The Investment Adviser cannot predict the effects of any new governmental regulation that may be implemented and there can be no assurance that any new governmental regulation will not adversely affect the Fund’s ability to achieve its investment objective.

Reliance on Service Providers Risk. The Fund must rely upon the performance of service providers to perform certain functions, which may include functions that are integral to the Fund’s operations and financial performance. Failure by any service provider to carry out its obligations to the Fund in accordance with the terms of its appointment, to exercise due care and skill or to perform its obligations to the Fund at all as a result of insolvency, bankruptcy or other causes could have a material adverse effect on the Fund’s performance and returns to shareholders. The termination of the Fund’s relationship with any service provider, or any delay in appointing a replacement for such service provider, could materially disrupt the business of the Fund and could have a material adverse effect on the Fund’s performance and returns to shareholders.

Cyber Security Risk. The Fund and its service providers are susceptible to cyber security risks that include, among other things, theft, unauthorized monitoring, release, misuse, loss, destruction or corruption of confidential and highly restricted data; denial of service attacks; unauthorized access to relevant systems, compromises to networks or devices that the Fund and its service providers use to service the Fund’s operations; or operational disruption or failures in the physical infrastructure or operating systems that support the Fund and its service providers. Cyber attacks are becoming increasingly common and more sophisticated, and may be perpetrated by computer hackers, cyber-terrorists or others engaged in corporate espionage. Cyber attacks against or security breakdowns of the Fund or its service providers may adversely impact the Fund and its stockholders, potentially resulting in, among other things, financial losses; the inability of Fund stockholders to transact business and

69

The Gabelli Convertible and Income Securities Fund Inc.

Additional Fund Information (Continued) (Unaudited)

the Fund to process transactions; inability to calculate the Fund’s NAV; violations of applicable privacy and other laws; regulatory fines, penalties, reputational damage, reimbursement or other compensation costs; and/or additional compliance costs. The Fund may incur additional costs for cyber security risk management and remediation purposes. In addition, cyber security risks may also impact issuers of securities in which the Fund invests, which may cause the Fund’s investment in such issuers to lose value. There have been a number of recent highly publicized cases of companies reporting the unauthorized disclosure of client or customer information, as well as cyberattacks involving the dissemination, theft and destruction of corporate information or other assets, as a result of failure to follow procedures by employees or contractors or as a result of actions by third parties, including actions by terrorist organizations and hostile foreign governments. Although service providers typically have policies and procedures, business continuity plans and/or risk management systems intended to identify and mitigate cyber incidents, there are inherent limitations in such plans and systems including the possibility that certain risks have not been identified. Furthermore, the Fund cannot control the cyber security policies, plans and systems put in place by its service providers or any other third parties whose operations may affect the Fund or its shareholders. There can be no assurance that the Fund or its service providers will not suffer losses relating to cyber attacks or other information security breaches in the future.

Because technology is consistently changing, new ways to carry out cyber attacks are always developing. Therefore, there is a chance that some risks have not been identified or prepared for, or that an attack may not be detected, which puts limitations on the Fund’s ability to plan for or respond to a cyber attack. In addition to deliberate cyber attacks, unintentional cyber incidents can occur, such as the inadvertent release of confidential information by the Fund or its service providers. Like other funds and business enterprises, the Fund and its service providers are subject to the risk of cyber incidents occurring from time to time.

Misconduct of Employees and of Service Providers Risk. Misconduct or misrepresentations by employees of the Investment Adviser or the Fund’s service providers could cause significant losses to the Fund. Employee misconduct may include binding the Fund to transactions that exceed authorized limits or present unacceptable risks and unauthorized trading activities, concealing unsuccessful trading activities (which, in any case, may result in unknown and unmanaged risks or losses) or making misrepresentations regarding any of the foregoing. Losses could also result from actions by the Fund’s service providers, including, without limitation, failing to recognize trades and misappropriating assets. In addition, employees and service providers may improperly use or disclose confidential information, which could result in litigation or serious financial harm, including limiting the Fund’s business prospects or future marketing activities. Despite the Investment Adviser’s due diligence efforts, misconduct and intentional misrepresentations may be undetected or not fully comprehended, thereby potentially undermining the Investment Adviser’s due diligence efforts. As a result, no assurances can be given that the due diligence performed by the Investment Adviser will identify or prevent any such misconduct.

Anti-Takeover Provisions. The Charter and Bylaws of the Fund include provisions that could limit the ability of other entities or persons to acquire control of the Fund or convert the Fund to an open-end fund.

Special Risks Related to Investment in Derivative Transactions. The Fund may participate in derivative transactions. Such transactions entail certain execution, market, liquidity, counterparty, correlation, volatility, hedging and tax risks. Participation in the options or futures markets, in currency exchange transactions and in other derivatives transactions involves investment risks and transaction costs to which the Fund would not be subject absent the use of these strategies. If the Investment Adviser’s prediction of movements in the direction

of the securities, foreign currency, interest rate or other referenced instruments or markets is inaccurate, the consequences to the Fund may leave the Fund in a worse position than if it had not used such strategies. Risks inherent in the use of options, swaps, foreign currency, futures contracts and options on futures contracts, securities indices and foreign currencies include:

| ● | dependence on the Investment Adviser’s ability to predict correctly movements in the direction of the relevant measure;

| ● | imperfect correlation between the price of the derivative instrument and movements in the prices of the referenced assets;

| ● | the fact that skills needed to use these strategies are different from those needed to select portfolio securities;

| ● | the possible absence of a liquid secondary market for any particular instrument at any time;

| ● | the possible need to defer closing out certain hedged positions to avoid adverse tax consequences;

| ● | the possible inability of the Fund to purchase or sell a security or instrument at a time that otherwise would be favorable for it to do so, or the possible need for the Fund to sell a security or instrument at a disadvantageous time due to a need for the Fund to remain in compliance with the 1940 Act restrictions regarding derivatives transaction; and

| ● | the creditworthiness of counterparties.

Options, futures contracts, swaps contracts, and options thereon and forward contracts on securities and currencies may be traded on foreign exchanges. Such transactions may not be regulated as effectively as similar transactions in the United States, may not involve a clearing mechanism and related guarantees, and are subject to the risk of governmental actions affecting trading in, or the prices of, foreign securities. The value of such positions also could be adversely affected by (i) other complex foreign political, legal and economic factors, (ii) lesser availability than in the United States of data on which to make trading decisions, (iii) delays in the ability of the Fund to act upon economic events occurring in the foreign markets during non-business hours in the United States, (iv) the imposition of different exercise and settlement terms and procedures and margin requirements than in the United States, and (v) less trading volume. Exchanges on which options, futures, swaps and options on futures or swaps are traded may impose limits on the positions that the Fund may take in certain circumstances.

Many OTC derivatives are valued on the basis of dealers’ pricing of these instruments. However, the price at which dealers value a particular derivative and the price which the same dealers would actually be willing to pay for such derivative should the Fund wish or be forced to sell such position may be materially different. Such differences can result in an overstatement of the Fund’s net asset value and may materially adversely affect the Fund in situations in which the Fund is required to sell derivative instruments. Exchange-traded derivatives and OTC derivative transactions submitted for clearing through a central counterparty have become subject to minimum initial and variation margin requirements set by the relevant clearinghouse, as well as possible margin requirements mandated by the SEC or the CFTC. These regulators also have broad discretion to impose margin requirements on non-cleared OTC derivatives. These margin requirements will increase the overall costs for the Fund.

While hedging can reduce or eliminate losses, it can also reduce or eliminate gains. Hedges are sometimes subject to imperfect matching between the derivative and the underlying security, and there can be no assurance that the Fund’s hedging transactions will be effective. Derivatives may give rise to a form of leverage and may expose the Fund to greater risk and increase its costs. Future CFTC or SEC rulemakings could potentially further limit or completely restrict the Fund’s ability to use these instruments as a part of the Fund’s investment strategy, increase the costs of using these instruments or make them less effective. Limits or restrictions applicable to the counterparties with which the Fund engages in derivative transactions could also prevent the Fund from using these instruments or affect the pricing or other factors relating to these instruments or may change the availability of certain investments. New regulation may make derivatives more costly, may limit the availability of derivatives, or may otherwise adversely affect the value or performance of derivatives.

Counterparty Risk. The Fund will be subject to credit risk with respect to the counterparties to the derivative contracts purchased by the Fund. If a counterparty becomes bankrupt or otherwise fails to perform its obligations under a derivative contract due to financial difficulties, the Fund may experience significant delays in obtaining any recovery under the derivative contract in bankruptcy or other reorganization proceeding. The Fund may obtain only a limited recovery or may obtain no recovery in such circumstances.

The counterparty risk for cleared derivatives is generally lower than for uncleared OTC derivative transactions since generally a clearing organization becomes substituted for each counterparty to a cleared derivative contract and, in effect, guarantees the parties’ performance under the contract as each party to a trade looks only to the clearing organization for performance of financial obligations under the derivative contract. However, there can be no assurance that a clearing organization, or its members, will satisfy its obligations to the Fund, or that the Fund would be able to recover the full amount of assets deposited on its behalf with the clearing organization in the event of the default by the clearing organization or the Fund’s clearing broker. In addition, cleared derivative transactions benefit from daily marking-to-market and settlement, and segregation and minimum capital requirements applicable to intermediaries. Uncleared OTC derivative transactions generally do not benefit from such protections. This exposes the Fund to the risk that a counterparty will not settle a transaction in accordance with its terms and conditions because of a dispute over the terms of the contract (whether or not bona fide) or because of a credit or liquidity problem, thus causing the Fund to suffer a loss. Such “counterparty risk” is accentuated for contracts with longer maturities where events may intervene to prevent settlement, or where the Fund has concentrated its transactions with a single or small group of counterparties.

or that the Fund would be able to recover the full amount of assets deposited on its behalf with the clearing organization in the event of the default by the clearing organization or the Fund’s clearing broker. In addition, cleared derivative transactions benefit from daily marking-to-market and settlement, and segregation and minimum capital requirements applicable to intermediaries. Uncleared OTC derivative transactions generally do not benefit from such protections.

Such “counterparty risk” is accentuated for contracts with longer maturities where events may intervene to prevent settlement, or where the Fund has concentrated its transactions with a single or small group of counterparties.

Swaps Risk. Swap agreements are two-party contracts entered into primarily by institutional investors for periods ranging from a few weeks to more than one year. In a standard “swap” transaction, two parties agree to exchange the returns (or differentials in rates of return) earned or realized on particular predetermined investments or instruments. The gross returns to be exchanged or “swapped” between the parties are calculated with respect to a “notional amount,” i.e., the return on or increase in value of a particular dollar amount invested at a particular interest rate, in a particular foreign currency, or in a “basket” of securities representing a particular index. The “notional amount” of the swap agreement is only a fictive basis on which to calculate the obligations that the parties to a swap agreement have agreed to exchange.

Historically, swap transactions have been individually negotiated non-standardized transactions entered into in the OTC markets and have not been subject to the same type of government regulation as exchange-traded instruments. However, in the U.S., the Dodd-Frank Wall Street Reform and Consumer Protection Act of 2010 (the “Dodd-Frank Act”) has made broad changes to the derivatives market, granted significant new authority to the CFTC and the SEC to regulate derivatives (swaps and security-based swaps) and participants in these markets. The Dodd-Frank Act is intended to regulate the derivatives market by requiring many derivative transactions to be cleared and traded on an exchange, expanding entity registration requirements, imposing business conduct requirements on dealers and requiring banks to move some derivatives trading units to a non-guaranteed affiliate separate from the deposit-taking bank or divest them altogether. See “Risk Factors and Special Considerations-General Risks-Derivatives Regulation Risk.”

Swap agreements will tend to shift the Fund’s investment exposure from one type of investment to another. For example, if the Fund agreed to pay fixed rates in exchange for floating rates while holding fixed-rate bonds, the swap would tend to decrease the Fund’s exposure to long-term interest rates. Caps and floors have an effect similar to buying or writing options. Depending on how they are used, swap agreements may increase or decrease the overall volatility of the Fund’s investments and its share price and yield. The most significant factor in the performance of swap agreements is the change in the specific interest rate, currency, or other factors that determine the amounts of payments due to and from the Fund. If a swap agreement calls for payments by the Fund, the Fund must be prepared to make such payments when due.

The Fund may enter into swap agreements that would calculate the obligations of the parties to the agreements on a “net” basis. Consequently, the Fund’s obligations (or rights) under a swap agreement will generally be equal only to the net amount to be paid or received under the agreement based on the relative values of the positions held by each party to the agreement (the “net amount”).

73

Additional Fund Information (Continued) (Unaudited)

The Fund’s use of swap agreements may not be successful in furthering its investment objective, as the Investment Adviser may not accurately predict whether certain types of investments are likely to produce greater returns than other investments. Moreover, swap agreements involve the risk that the party with whom a Fund has entered into the swap will default on its obligation to pay a Fund and the risk that a Fund will not be able to meet its obligations to pay the other party to the agreement. The Fund may be able to eliminate its exposure under a swap agreement either by assignment or other disposition, or by entering into an offsetting swap agreement with the same party or a similarly creditworthy party.

Forward Foreign Currency Exchange Contracts. The Fund may enter into forward foreign currency exchange contracts to protect the value of its portfolio against uncertainty in the level of future currency exchange rates between a particular foreign currency and the U.S. dollar or between foreign currencies in which its securities are or may be denominated. The Fund may enter into such contracts on a spot (i.e., cash) basis at the rate then prevailing in the currency exchange market or on a forward basis, by entering into a forward contract to purchase or sell currency. A forward contract on foreign currency is an obligation to purchase or sell a specific currency at a future date, which may be any fixed number of days agreed upon by the parties from the date of the contract at a price set on the date of the contract. Forward currency contracts (i) are traded in a market conducted directly between currency traders (typically, commercial banks or other financial institutions) and their customers, (ii) generally have no deposit requirements and (iii) are typically consummated without payment of any commissions. The Fund, however, may enter into forward currency contracts requiring deposits or involving the payment of commissions.

The dealings of the Fund in forward foreign exchange are limited to hedging involving either specific transactions or portfolio positions. Transaction hedging is the purchase or sale of one forward foreign currency for another currency with respect to specific receivables or payables of the Fund accruing in connection with the purchase and sale of its portfolio securities or its payment of distributions. Position hedging is the purchase or sale of one forward foreign currency for another currency with respect to portfolio security positions denominated or quoted in the foreign currency to offset the effect of an anticipated substantial appreciation or depreciation, respectively, in the value of the currency relative to the U.S. dollar. In this situation, the Fund also may, for example, enter into a forward contract to sell or purchase a different foreign currency for a fixed U.S. dollar amount where it is believed that the U.S. dollar value of the currency to be sold or bought pursuant to the forward contract will fall or rise, as the case may be, whenever there is a decline or increase, respectively, in the U.S. dollar value of the currency in which its portfolio securities are denominated (this practice being referred to as a “cross-hedge”).

In hedging a specific transaction, the Fund may enter into a forward contract with respect to either the currency in which the transaction is denominated or another currency deemed appropriate by the Investment Adviser. The amount the Fund may invest in forward currency contracts is limited to the amount of its aggregate investments in foreign currencies.

The use of forward currency contracts may involve certain risks, including the failure of the counterparty to perform its obligations under the contract, and such use may not serve as a complete hedge because of an imperfect correlation between movements in the prices of the contracts and the prices of the currencies hedged or used for cover. The Fund will only enter into forward currency contracts with parties which the Investment Adviser believes to be creditworthy institutions.

Futures Contracts and Options on Futures. Futures and options on futures entail certain risks, including but not limited to the following: no assurance that futures contracts or options on futures can be offset at favorable prices; possible reduction of the yield of the Fund due to the use of hedging; possible reduction in value of both the securities hedged and the hedging instrument; possible lack of liquidity due to daily limits on price fluctuations; imperfect correlation between the contracts and the securities being hedged; and losses from investing in futures transactions that are potentially unlimited.

Options Risk. To the extent that the Fund purchases options pursuant to a hedging strategy, the Fund will be subject to the following additional risks. If a put or call option purchased by the Fund is not sold when it has remaining value, and if the market price of the underlying security remains equal to or greater than the exercise price (in the case of a put), or remains less than or equal to the exercise price (in the case of a call), the Fund will lose its entire investment in the option.

Where a put or call option on a particular security is purchased to hedge against price movements in that or a related security, the price of the put or call option may move more or less than the price of the security. If restrictions on exercise are imposed, the Fund may be unable to exercise an option it has purchased. If the Fund is unable to close out an option that it has purchased on a security, it will have to exercise the option in order to realize any profit or the option may expire worthless.

Derivatives Regulation Risk. The Dodd-Frank Act has made broad changes to the derivatives market, granted significant new authority to the CFTC and the SEC to regulate derivatives (swaps and security-based swaps) and participants in these markets. The Dodd-Frank Act is intended to regulate the derivatives market by requiring many derivative transactions to be cleared and traded on an exchange, expanding entity registration requirements, imposing business conduct requirements on dealers and requiring banks to move some derivatives trading units to a non-guaranteed affiliate separate from the deposit-taking bank or divest them altogether. The CFTC has implemented mandatory clearing and exchange-trading of certain derivatives contracts including many standardized interest rate swaps and credit default index swaps. The CFTC continues to approve contracts for central clearing. Exchange-trading and central clearing are expected to reduce counterparty credit risk by substituting the clearinghouse as the counterparty to a swap and increase liquidity, but exchange-trading and central clearing do not make swap transactions risk-free. Uncleared swaps, such as non-deliverable foreign currency forwards, are subject to certain margin requirements that mandate the posting and collection of minimum margin amounts. This requirement may result in the Fund and its counterparties posting higher margin amounts for uncleared swaps than would otherwise be the case. Certain rules require centralized reporting of detailed information about many types of cleared and uncleared swaps. Reporting of swap data may result in greater market transparency, but may subject the Fund to additional administrative burdens, and the safeguards established to protect trader anonymity may not function as expected.

In addition, the Fund is required to comply with the Rule 18f-4 limits described previously under “Special Risks Related to Investment in Derivatives” on the amount of derivatives the Fund can enter into, eliminate the asset segregation framework previously used to comply with Section 18 of the 1940 Act, treat derivatives as senior securities so that a failure to comply with the limits would result in a statutory violation and require the Fund, if the Fund’s use of derivatives is more than a limited specified exposure amount (10% of net assets), to establish and maintain a comprehensive derivatives risk management program and appoint a derivatives risk manager. These requirements may limit the ability of the Fund to invest in derivatives, engage in securities

75

Additional Fund Information (Continued) (Unaudited)

lending activities, short sales, reverse repurchase agreements and similar financing transactions. Additionally, Rule 18f-4 may affect the Fund’s ability to implement its investment strategy, pursue its investment objectives and may increase the cost of the Fund’s investments.

Special Risks to Holders of Notes

An investment in our notes is subject to special risks. Our notes are not likely to be listed on an exchange or automated quotation system. We cannot assure you that any market will exist for our notes or if a market does exist, whether it will provide holders with liquidity. Broker-dealers that maintain a secondary trading market for the notes are not required to maintain this market, and the Fund is not required to redeem notes if an attempted secondary market sale fails because of a lack of buyers. To the extent that our notes trade, they may trade at a price either higher or lower than their principal amount depending on interest rates, the rating (if any) on such notes and other factors.

Special Risks to Holders of Preferred Shares

Illiquidity Prior to Exchange Listing. Prior to the offering of any additional series of preferred shares, there will be no public market for such shares. In the event any preferred shares are issued, prior application will have been made to list such shares on the NYSE. However, during an initial period, which is not expected to exceed 30 days after the date of initial issuance, such shares may not be listed on any securities exchange. During such period, the underwriters may make a market in such shares, though, they will have no obligation to do so. Consequently, an investment in such shares may be illiquid during such period.

Market Price Fluctuation. Preferred shares may trade at a premium to or discount from liquidation preference for a variety of reasons, including changes in interest rates.

Special Risks to Holders of Notes and Preferred Shares

Common Share Repurchases. Repurchases of common shares by the Fund may reduce the net asset coverage of the notes and preferred shares, which could adversely affect their liquidity or market prices.

Common Share Distribution Policy. In the event the Fund does not generate a total return from dividends and interest received and net realized capital gains in an amount at least equal to the greater of its stated distribution policy or the minimum distribution requirements of the Code in a given year, the Fund expects that it would return capital as part of its distribution. This would decrease the asset coverage per share with respect to the Fund’s notes or preferred shares, which could adversely affect their liquidity or market prices.

For the fiscal year ended September 30, 2025, the Fund made distributions of $0.48 per common share, a portion of which constituted a return of capital. The composition of each distribution is estimated based on the earnings of the Fund as of the record date for each distribution. The actual composition of each of the current year’s distributions will be based on the Fund’s investment activity through the end of the calendar year.

Credit Quality Ratings. The Fund may obtain credit quality ratings for its preferred shares or notes; however, it is not required to do so and may issue preferred shares or notes without any rating. If rated, the Fund does not

76

The Gabelli Convertible and Income Securities Fund Inc.

Additional Fund Information (Continued) (Unaudited)

impose any minimum rating necessary to issue such preferred shares or notes. In order to obtain and maintain attractive credit quality ratings for preferred shares or borrowings, if desired, the Fund’s portfolio must satisfy over-collateralization tests established by the relevant rating agencies. These tests are more difficult to satisfy to the extent the Fund’s portfolio securities are of lower credit quality, longer maturity or not diversified by issuer and industry. These guidelines could affect portfolio decisions and may be more stringent than those imposed by the 1940 Act. With respect to ratings (if any) of the notes or preferred shares, a rating by a ratings agency does not eliminate or necessarily mitigate the risks of investing in our preferred shares or notes, and a rating may not fully or accurately reflect all of the securities’ credit risks. A rating does not address the liquidity or any other market risks of the securities being rated. A rating agency could downgrade the rating of our notes or preferred shares, which may make such securities less liquid in the secondary market. If a rating agency downgrades the rating assigned to our preferred shares or notes, we may alter our portfolio or redeem the preferred shares or notes under certain circumstances.

Special Risks of Notes to Holders of Preferred Shares

As provided in the 1940 Act, and subject to compliance with the Fund’s investment limitations, the Fund may issue notes. In the event the Fund were to issue such securities, the Fund’s obligations to pay dividends or make distributions and, upon liquidation of the Fund, liquidation payments in respect of its preferred shares would be subordinate to the Fund’s obligations to make any principal and interest payments due and owing with respect to its outstanding notes. Accordingly, the Fund’s issuance of notes would have the effect of creating special risks for the Fund’s preferred shareholders that would not be present in a capital structure that did not include such securities.

Special Risks to Holders of Common Shares

Dilution Risk. If the Fund determines to conduct a rights offering to subscribe for common shares, holders of common shares may experience dilution or accretion of the aggregate net asset value of their common shares. Such dilution or accretion will depend upon whether (i) such shareholders participate in the rights offering and (ii) the Fund’s net asset value per common share is above or below the subscription price on the expiration date of the rights offering.

Shareholders who do not exercise their subscription rights may, at the completion of such an offering, own a smaller proportional interest in the Fund than if they exercised their subscription rights. As a result of such an offering, a shareholder may experience dilution in net asset value per share if the subscription price per share is below the net asset value per share on the expiration date. If the subscription price per share is below the net asset value per share of the Fund’s shares on the expiration date, a shareholder will experience an immediate dilution of the aggregate net asset value of such shareholder’s shares if the shareholder does not participate in such an offering and the shareholder will experience a reduction in the net asset value per share of such shareholder’s shares whether or not the shareholder participates in such an offering. The Fund cannot state precisely the extent of this dilution (if any) if the shareholder does not exercise such shareholder’s subscription

77

The Gabelli Convertible and Income Securities Fund Inc.

Additional Fund Information (Continued) (Unaudited)

rights because the Fund does not know what the net asset value per share will be when the offer expires or what proportion of the subscription rights will be exercised.

There is also a risk that the Fund’s largest shareholders, record date shareholders of more than 5% of the outstanding shares of common stock of the Fund, may increase their percentage ownership of the Fund through the exercise of the primary subscription and over-subscription privilege.

Leverage Risk. The Fund currently uses financial leverage for investment purposes by issuing preferred shares and is also permitted to use other types of financial leverage, such as through the issuance of debt securities or additional preferred shares and borrowing from financial institutions. As provided in the 1940 Act and subject to certain exceptions, the Fund may issue additional senior securities (which may be stock, such as preferred shares, and/or securities representing debt) only if immediately after such issuance the value of the Fund’s total assets, less certain ordinary course liabilities, exceeds 300% of the amount of the debt outstanding and exceeds 200% of the amount of preferred shares and debt outstanding. As of September 30, 2025, the amount of leverage represented approximately 7% of the Fund’s assets.

The Fund’s leveraged capital structure creates special risks not associated with unleveraged funds having a similar investment objective and policies. These include the possibility of greater loss and the likelihood of higher volatility of the net asset value of the Fund and the asset coverage for the preferred shares. Such volatility may increase the likelihood of the Fund having to sell investments in order to meet its obligations to make distributions on the preferred shares or principal or interest payments on debt securities, or to redeem preferred shares or repay debt, when it may be disadvantageous to do so. The Fund’s use of leverage may require it to sell portfolio investments at inopportune times in order to raise cash to redeem preferred shares or otherwise de-leverage so as to maintain required asset coverage amounts or comply with the mandatory redemption terms of any outstanding preferred shares. The use of leverage magnifies both the favorable and unfavorable effects of price movements in the investments made by the Fund. To the extent that the Fund employs leverage in its investment operations, the Fund is subject to substantial risk of loss. The Fund cannot assure you that borrowings or the issuance of preferred shares will result in a higher yield or return to the holders of the common shares. Also, since the Fund utilizes leverage, a decline in net asset value could affect the ability of the Fund to make common share distributions and such a failure to make distributions could result in the Fund ceasing to qualify as a RIC under the Code.

Any decline in the net asset value of the Fund’s investments would be borne entirely by the holders of common shares. Therefore, if the market value of the Fund’s portfolio declines, the leverage will result in a greater decrease in net asset value to the holders of common shares than if the Fund were not leveraged. This greater net asset value decrease will also tend to cause a greater decline in the market price for the common shares. The Fund might be in danger of failing to maintain the required asset coverage of its borrowings, notes or preferred shares or of losing its ratings on its notes or preferred shares or notes or, in an extreme case, the Fund’s current investment income might not be sufficient to meet the distribution or interest requirements on the borrowings, preferred shares or notes. In order to counteract such an event, the Fund might need to liquidate investments in order to fund a redemption or repayment of some or all of the borrowings, preferred shares or notes.

78

Preferred Share and Note Risk. The issuance of preferred shares or notes causes the net asset value and market value of the common shares to become more volatile. If the dividend rate on the preferred shares or the interest rate on the notes approaches the net rate of return on the Fund’s investment portfolio, the benefit of leverage to the holders of the common shares would be reduced. If the dividend rate on the preferred shares or the interest rate on the notes plus the management fee rate of 1.00% exceeds the net rate of return on the Fund’s portfolio, the leverage will result in a lower rate of return to the holders of common shares than if the Fund had not issued preferred shares or notes. If the Fund has insufficient investment income and gains, all or a portion of the distributions to preferred shareholders or interest payments to note holders would come from the common shareholders’ capital. Such distributions and interest payments reduce the net assets attributable to common shareholders. The prospectus or prospectus supplement relating to any public offering of preferred shares will set forth dividend rate on such preferred shares.

In addition, the Fund would pay (and the holders of common shares will bear) all costs and expenses relating to the issuance and ongoing maintenance of the preferred shares or notes, including the advisory fees on the incremental assets attributable to the preferred shares or notes.

Holders of preferred shares and notes may have different interests than holders of common shares and may at times have disproportionate influence over the Fund’s affairs. As provided in the 1940 Act and subject to certain exceptions, the Fund may issue senior securities (which may be stock, such as preferred shares, and/or securities representing debt, such as notes) only if immediately after the issuance the value of the Fund’s total assets, less certain ordinary course liabilities, exceeds 300% of the amount of the debt outstanding (i.e., for every dollar of indebtedness outstanding, the Fund is required to have at least three dollars of assets) and exceeds 200% of the amount of preferred shares and debt outstanding (i.e., for every dollar in liquidation preference of preferred stock outstanding, the Fund is required to have two dollars of assets), which is referred to as the “asset coverage” required by the 1940 Act. In the event the Fund fails to maintain an asset coverage of 100% for any notes outstanding for certain periods of time, the 1940 Act requires that either an event of default be declared or that the holders of such notes have the right to elect a majority of the Fund’s Directors until asset coverage recovers to 110%. In addition, holders of preferred shares, voting separately as a single class, have the right (subject to the rights of noteholders) to elect two members of the Board at all times and in the event dividends become two full years in arrears would have the right to elect a majority of the Directors until such arrearage is completely eliminated. In addition, preferred shareholders have class voting rights on certain matters, including changes in fundamental investment restrictions and conversion of the Fund to open-end status, and accordingly can veto any such changes. Further, interest on notes will be payable when due as described in a prospectus or prospectus supplement relating to the public offering of such notes and if the Fund does not pay interest when due, it will trigger an event of default and the Fund expects to be restricted from declaring dividends and making other distributions with respect to common shares and preferred shares. Upon the occurrence and continuance of an event of default, the holders of a majority in principal amount of a series of outstanding notes or the trustee will be able to declare the principal amount of that series of notes immediately due and payable upon written notice to the Fund. The 1940 Act also generally restricts the Fund from declaring distributions on, or repurchasing, common or preferred shares unless notes have an asset coverage of 300% (200% in the case of declaring distributions on preferred shares). The Fund’s common shares are structurally subordinated as to income and residual value to any preferred shares or notes in the Fund’s capital structure, in terms of priority to income and payment in liquidation.

Restrictions imposed on the declarations and payment of dividends or other distributions to the holders of the Fund’s common shares and preferred shares, both by the 1940 Act and by requirements imposed by rating agencies, might impair the Fund’s ability to maintain its qualification as a RIC for U.S. federal income tax purposes. While the Fund intends to redeem its preferred shares or notes to the extent necessary to enable the Fund to distribute its income as required to maintain its qualification as a RIC under the Code, there can be no assurance that such actions can be effected in time to meet the Code requirements.

Portfolio order to obtain and maintain attractive credit quality ratings for preferred shares or borrowings, the Fund must comply with investment quality, diversification and other guidelines established by the relevant rating agencies. These guidelines could affect portfolio decisions and may be more stringent than those imposed by the 1940 Act. In the event that a rating on the Fund’s preferred shares or notes is lowered or withdrawn by the relevant rating agency, the Fund may also be required to redeem all or part of its outstanding preferred shares or notes, and the common shares of the Fund will lose the potential benefits associated with a leveraged capital structure.

Impact that leverage will (1) be equal in amount to approximately 7% of the Fund’s total net assets (the Fund’s outstanding financial leverage as of September 30, 2025), and (2) charge interest or involve dividend payments at a projected blended annual average leverage dividend or interest rate of 5.20%, (the average dividend rate on the Fund’s outstanding financial leverage as of September 30, 2025) then the total return generated by the Fund’s portfolio (net of estimated expenses) must exceed approximately 0.35% of the Fund’s total net assets in order to cover such interest or dividend payments and other expenses specifically related to leverage. Of course, these numbers are merely estimates, used for illustration. Actual dividend rates, interest or payment rates may vary frequently and may be significantly higher or lower than the rate estimated above. The following table is furnished in response to requirements of the SEC. It is designed to illustrate the effect of leverage on common share total return, assuming investment portfolio total returns (comprised of net investment income of the Fund, realized gains or losses of the Fund and changes in the value of the securities held in the Fund’s portfolio) of -10%, -5%, 0%, 5% and 10%. These assumed investment portfolio returns are hypothetical figures and are not necessarily indicative of the investment portfolio returns experienced or expected to be experienced by the Fund. The table further reflects leverage representing 7% of the Fund’s net assets (the Fund’s amount of outstanding financial leverage at September 30, 2025), the Fund’s current projected blended annual average leverage dividend or interest rate of 5.20% (the average dividend rate on the Fund’s outstanding financial leverage as of September 30, 2025), a base management fee at an annual rate of 1.00% of the liquidation preference of any outstanding preferred shares and estimated annual incremental expenses attributable to any outstanding preferred shares of 0.01% of the Fund’s net assets attributable to common shares.

Assumed Return on Portfolio (Net of Expenses) |  |  | (10 | )% |  |  | (5 | )% |  |  | 0 | % |  |  | 5 | % |  |  | 10 | %
Corresponding Return to Common Shareholder |  |  | (11.13 | )% |  |  | (5.78 | )% |  |  | (0.43 | )% |  |  | 4.92 | % |  |  | 10.26 | %

Common share total return is composed of two elements—the common share distributions paid by the Fund (the amount of which is largely determined by the taxable income of the Fund (including realized gains or losses) after paying interest on any debt and/or dividends on any preferred shares) and unrealized gains or

losses on the value of the securities the Fund owns. As required by SEC rules, the table assumes that the Fund is more likely to suffer capital losses than to enjoy total return. For example, to assume a total return of 0% the Fund must assume that the income it receives on its investments is entirely offset by expenses and losses in the value of those investments.

Market Discount Risk. As described above in “—General Risks—Market Discount Risk,” common shares of closed-end funds often trade at a discount to their net asset values and the Fund’s common shares may trade at such a discount. This risk may be greater for investors expecting to sell their common shares of the Fund soon after completion of a public offering. The common shares of the Fund are designed primarily for long term investors and investors in the shares should not view the Fund as a vehicle for trading purposes.

Special Risk to Holders of Subscription Rights

There is a risk that changes in market conditions may result in the underlying common or preferred shares purchasable upon exercise of the subscription rights being less attractive to investors at the conclusion of the subscription period. This may reduce or eliminate the value of the subscription rights. Investors who receive subscription rights may find that there is no market to sell rights they do not wish to exercise. If investors exercise only a portion of the rights, the number of common or preferred shares issued may be reduced, and the common or preferred shares may trade at less favorable prices than larger offerings for similar securities.

INVESTMENT POLICIES

Additional Investment Policies

Unregistered Convertible Securities and Other Illiquid Investments. As Fund is not subject to an independent limitation on the amount it may invest in unregistered securities and other illiquid investments, including repurchase agreements having a maturity of longer than seven days.

The staff of the SEC has taken the position that purchased OTC options and the assets used as “cover” for written OTC options are illiquid. The assets used as cover for OTC options written by the Fund will be considered illiquid unless the OTC options are sold to qualified dealers who agree that the Fund may repurchase any OTC option it writes at a maximum price to be calculated by a formula set forth in the option agreement. The cover for an OTC option written subject to this procedure will be considered illiquid only to the extent that the maximum repurchase price under the option formula exceeds the intrinsic value of the option.

When Issued and Delayed Delivery Securities and Forward Commitments. As Fund may purchase securities on a “when, as and if issued” basis under which the issuance of the security depends upon the occurrence of a subsequent event, such as approval of a merger, corporate reorganization or debt restructuring. The commitment for the purchase of any such security will not be recognized in the portfolio of the Fund until the Investment Adviser determines that issuance of the security is probable. At such time, the Fund will record the transaction and, in determining its net asset value, will reflect the value of the security daily. The Investment Adviser does not believe that the net asset value of the Fund will be adversely affected by its purchase of securities on this basis.

Foreign Securities. Subject to the limitations described in this Annual Report, the Fund may invest in securities of non-U.S. issuers, which involve certain risks not associated with domestic investments.

Among other risks, foreign markets have different clearance and settlement procedures, and in certain markets there have been times when settlements have failed to keep pace with the volume of securities transactions, making it difficult to conduct such transactions. Delays in settlements could result in temporary periods when assets of the Fund are uninvested and no return is earned thereon. The inability of the Fund to make intended security purchases due to settlement problems could cause the Fund to miss attractive investment opportunities. Inability to dispose of a portfolio security due to settlement problems could result either in losses to the Fund due to subsequent declines in the value of such portfolio security or, if the Fund has entered into a contract to sell the security, could result in possible liability to the purchaser.

Frontier Markets Risk. Frontier countries generally have smaller economies or less developed capital markets than traditional emerging markets, and, as a result, the risks of investing in emerging market countries are magnified in frontier countries. The economies of frontier countries are less correlated to global economic cycles than those of their more developed counterparts and their markets have low trading volumes and the potential for extreme price volatility and illiquidity. This volatility may be further heightened by the actions of a few major investors. For example, a substantial increase or decrease in the cash flows of mutual funds investing in these markets could significantly affect local stock prices and, therefore, the NAV of Fund’s common stock. These factors make investing in frontier countries significantly riskier than in other countries and any one of them could cause the NAV of the Fund’s shares to decline.

Governments of many frontier countries in which the Fund may invest may exercise substantial influence over many aspects of the private sector. In some cases, the governments of such frontier countries may own or control certain companies. Accordingly, government actions could have a significant effect on economic conditions in a frontier country and on market conditions, prices and yields of securities in the Fund’s portfolio. Moreover, the economies of frontier countries may be heavily dependent upon international trade and, accordingly, have been and may continue to be, adversely affected by trade barriers, exchange controls, managed adjustments in relative currency values and other protectionist measures imposed or negotiated by the countries with which they trade. These economies also have been and may continue to be adversely affected by economic conditions in the countries with which they trade.

Options. The Fund may purchase or write call or put options on securities or indices. In the case of call options, the exercise prices are referred to as “in-the-money,” “at-the-money,” and “out-of-the-money,” respectively. The Fund may write (a) in-the-money call options when Gabelli Funds, LLC (the “Investment Adviser”) expects that the price of the underlying security will remain stable or decline during the option period, (b) at-the-money call options when the Investment Adviser expects that the price of the underlying security will remain stable, decline, or advance moderately during the option period, and (c) out-of-the-money call options when the Investment Adviser expects that the premiums received from writing the call option will be greater than the appreciation in the price of the underlying security above the exercise price. By writing a call option, the Fund limits its opportunity to profit from any increase in the market value of the underlying security above the exercise price of the option. Out-of-the-money, at-the-money, and in-the-money put options (the reverse of call options as to the relation of exercise price to market price) may be utilized in the same market environments that such call options are used in equivalent transactions.

Options on Securities Indices. The Fund may purchase and sell securities index options. One effect of such transactions may be to hedge all or part of the Fund’s securities holdings against a general decline in the

82

The Gabelli Convertible and Income Securities Fund Inc.

Additional Fund Information (Continued) (Unaudited)

securities market or a segment of the securities market. Options on securities indices are similar to options on stocks except that, rather than the right to take or make delivery of stock at a specified price, an option on a securities index gives the holder the right to receive, upon exercise of the option, an amount of cash if the closing level of the securities index upon which the option is based is greater than, in the case of a call option, or less than, in the case of a put option, the exercise price of the option.

The Fund’s successful use of options on indices depends upon its ability to predict the direction of the market and is subject to various additional risks. The correlation between movements in the index and the price of the securities being hedged against is imperfect and the risk from imperfect correlation increases as the composition of the Fund diverges from the composition of the relevant index. Accordingly, a decrease in the value of the securities being hedged against may not be wholly offset by a gain on the exercise or sale of a securities index put option held by the Fund.

Options on Foreign Currencies. . Instead of purchasing or selling currency futures (as described below), the Fund may attempt to accomplish similar objectives by purchasing put or call options on currencies or by writing put options or call options on currencies either on exchanges or in OTC markets. A put option gives the Fund the right to sell a currency at the exercise price until the option expires. A call option gives the Fund the right to purchase a currency at the exercise price until the option expires. Both types of options serve to insure against adverse currency price movements in the underlying portfolio assets designated in a given currency. The Fund’s use of options on currencies will be subject to the same limitations as its use of options on securities, described herein. Currency options may be subject to position limits which may limit the ability of the Fund to fully hedge its positions by purchasing the options.

As in the case of interest rate futures contracts and options thereon, described below, the Fund may hedge against the risk of a decrease or increase in the U.S. dollar value of a foreign currency denominated debt security which the Fund owns or intends to acquire by purchasing or selling options contracts, futures contracts or options thereon with respect to a foreign currency other than the foreign currency in which such debt security is denominated, where the values of such different currencies (vis-à-vis the U.S. dollar) historically have a high degree of positive correlation.

Futures Contracts and Options on Futures. The Fund may purchase and sell financial futures contracts and options thereon which are traded on a commodities exchange or board of trade for certain hedging and risk management purposes. A financial futures contract is an agreement to purchase or sell an agreed amount of securities or currencies at a set price for delivery in the future. These futures contracts and related options may be on debt securities, financial indices, securities indices, U.S. government securities and foreign currencies.

A “sale” of a futures contract (or a “short” futures position) means the assumption of a contractual obligation to deliver the securities underlying the contract at a specified price at a specified future time. A “purchase” of a futures contract (or a “long” futures position) means the assumption of a contractual obligation to acquire the securities underlying the contract at a specified price at a specified future time. Certain futures contracts, including stock and bond index futures, are settled on a net cash payment basis rather than by the sale and delivery of the securities underlying the futures contracts.

No consideration will be paid or received by the Fund upon the purchase or sale of a futures contract. Initially, the Fund will be required to deposit with the broker an amount of cash or cash equivalents equal to approximately

83

The Gabelli Convertible and Income Securities Fund Inc.

Additional Fund Information (Continued) (Unaudited)

1% to 10% of the contract amount (this amount is subject to change by the exchange or board of trade on which the contract is traded and brokers or members of such board of trade may charge a higher amount). This amount is known as the “initial margin” and is in the nature of a performance bond or good faith deposit on the contract. Subsequent payments, known as “variation margin,” to and from the broker will be made daily as the price of the index or security underlying the futures contract fluctuates. At any time prior to the expiration of the futures contract, the Fund may elect to close the position by taking an opposite position, which will operate to terminate its existing position in the contract.

An option on a futures contract gives the purchaser the right, in return for the premium paid, to assume a position in a futures contract at a specified exercise price at any time prior to the expiration of the option. Upon exercise of an option, the delivery of the futures position by the writer of the option to the holder of the option will be accompanied by delivery of the accumulated balance in the writer’s futures margin account attributable to that contract, which represents the amount by which the market price of the futures contract exceeds, in the case of a call option, or is less than, in the case of a put option, the exercise price of the option on the futures contract. The potential loss related to the purchase of an option on a futures contract is limited to the premium paid for the option (plus transaction costs). Because the value of the option purchased is fixed at the point of sale, there are no daily cash payments by the purchaser to reflect changes in the value of the underlying contract; however, the value of the option does change daily and that change would be reflected in the net assets of the Fund.

Futures and options on futures entail certain risks, including but not limited to the following: no assurance that futures contracts or options on futures can be offset at favorable prices, possible reduction of the yield of the Fund due to the use of hedging, possible reduction in value of both the securities hedged and the hedging instrument, possible lack of liquidity due to daily limits on price fluctuations, imperfect correlation between the contracts and the securities being hedged, losses from investing in futures transactions that are potentially unlimited.

Contingent Convertible Securities. One type of convertible security in which the Fund may invest is contingent convertible securities, sometimes referred to as “CoCos.” CoCos are a form of hybrid debt security issued by banking institutions that are intended to either automatically convert into equity or have their principal written down upon the occurrence of certain “trigger events,” which may include a decline in the issuer’s capital below a specified threshold level, increase in the issuer’s risk weighted assets, the share price of the issuer falling to a particular level for a certain period of time and certain regulatory events. CoCos’ unique equity conversion or principal write-down features are tailored to the issuing banking institution and its regulatory requirements.

CoCos are a newer form of instrument and the regulatory environment for these instruments continues to evolve. Because the market for such securities is evolving, it is uncertain how the larger market for CoCos would react to a trigger event, coupon cancellation, write-down of par value or coupon suspension (as described below) applicable to a single issuer. Following conversion of a CoCo, because the common stock of the issuer may not pay a dividend, investors in such securities could experience reduced yields or no yields at all.

Loss Absorption Risk. CoCos have fully discretionary coupons. This means coupons can potentially be cancelled at the banking institution’s discretion or at the request of the relevant regulatory authority in order to help the bank absorb losses. The liquidation value of a CoCo may be adjusted downward to below the original par value or written off entirely under certain circumstances. The write-down of the security’s par value may occur

84

The Gabelli Convertible and Income Securities Fund Inc.

Additional Fund Information (Continued) (Unaudited)

automatically and would not entitle holders to institute bankruptcy proceedings against the issuer. In addition, an automatic write-down could result in a reduced income rate if the dividend or interest payment associated with the security is based on the security’s par value. Coupon payments may also be subject to approval by the issuer’s regulator and may be suspended in the event there are insufficient distributable reserves. Due to uncertainty surrounding coupon payments, CoCos may be volatile and their price may decline rapidly in the event that coupon payments are suspended.

Subordinated Instruments. CoCos will, in the majority of circumstances, be issued in the form of subordinated debt instruments in order to provide the appropriate regulatory capital treatment prior to a conversion. Accordingly, in the event of liquidation, dissolution or winding-up of an issuer prior to a conversion having occurred, the rights and claims of the holders of the CoCos, such as the Fund, against the issuer in respect of or arising under the terms of the CoCos shall generally rank junior to the claims of all holders of unsubordinated obligations of the issuer. In addition, if the CoCos are converted into the issuer’s underlying equity securities following a conversion event (i.e., a “trigger”), each holder will be subordinated due to their conversion from being the holder of a debt instrument to being the holder of an equity instrument. Such conversion may be automatic.

Unpredictable Market Value Fluctuate. The value of CoCos is unpredictable and will be influenced by many factors including, without limitation: (i) the creditworthiness of the issuer and/or fluctuations in such issuer’s applicable capital ratios; (ii) supply and demand for the CoCos; (iii) general market conditions and available liquidity; and (iv) economic, financial and political events that affect the issuer, its particular market or the financial markets in general.

Interest Rate Futures Contracts and Options Thereon. The Fund may purchase or sell interest rate futures contracts to take advantage of or to protect the Fund against fluctuations in interest rates affecting the value of debt securities which the Fund holds or intends to acquire. For example, if interest rates are expected to increase, the Fund might sell futures contracts on debt securities, the values of which historically have a high degree of positive correlation to the values of the Fund’s portfolio securities. Such a sale would have an effect similar to selling an equivalent value of the Fund’s portfolio securities. If interest rates increase, the value of the Fund’s portfolio securities will decline, but the value of the futures contracts to the Fund will increase at approximately an equivalent rate thereby keeping the net asset value of the Fund from declining as much as it otherwise would have. The Fund could accomplish similar results by selling debt securities with longer maturities and investing in debt securities with shorter maturities when interest rates are expected to increase. However, since the futures market may be more liquid than the cash market, the use of futures contracts as a risk management technique allows the Fund to maintain a defensive position without having to sell its portfolio securities.

Similarly, the Fund may purchase interest rate futures contracts when it is expected that interest rates may decline. The purchase of futures contracts for this purpose constitutes a hedge against increases in the price of debt securities (caused by declining interest rates) which the Fund intends to acquire. Since fluctuations in the value of appropriately selected futures contracts should approximate that of the debt securities that will be purchased, the Fund can take advantage of the anticipated rise in the cost of the debt securities without actually buying them. Subsequently, the Fund can make its intended purchase of the debt securities in the cash market and liquidate its futures position.

85

The purchase of a call option on a futures contract is similar in some respects to the purchase of a call option on an individual security. Depending on the pricing of the option compared to either the price of the futures contract upon which it is based or the price of the underlying debt securities, it may or may not be less risky than ownership of the futures contract or underlying debt securities. As with the purchase of futures contracts, when the Fund is not fully invested it may purchase a call option on a futures contract to hedge against a market advance due to declining interest rates.

The purchase of a put option on a futures contract is similar to the purchase of protective put options on portfolio securities. The Fund will purchase a put option on a futures contract to hedge the Fund’s portfolio against the risk of rising interest rates and a consequent reduction in the value of portfolio securities.

The writing of a call option on a futures contract constitutes a partial hedge against declining prices of the securities which are deliverable upon exercise of the futures contract. If the futures price at expiration of the option is below the exercise price, the Fund will retain the full amount of the option premium which provides a partial hedge against any decline that may have occurred in the Fund’s portfolio holdings. The writing of a put option on a futures contract constitutes a partial hedge against increasing prices of the securities that are deliverable upon exercise of the futures contract. If the futures price at expiration of the option is higher than the exercise price, the Fund will retain the full amount of the option premium, which provides a partial hedge against any increase in the price of debt securities that the Fund intends to purchase. If a put or call option the Fund has written is exercised, the Fund will incur a loss which will be reduced by the amount of the premium it received. Depending on the degree of correlation between changes in the value of its portfolio securities and changes in the value of its futures positions, the Fund’s losses from options on futures it has written may to some extent be reduced or increased by changes in the value of its portfolio securities.

Currency Futures and Options Thereon. Generally, foreign currency futures contracts and options thereon are similar to the interest rate futures contracts and options thereon discussed previously. By entering into currency futures and options thereon, the Fund will seek to establish the rate at which it will be entitled to exchange U.S. dollars for another currency at a future time. By selling currency futures, the Fund will seek to establish the number of dollars it will receive at delivery for a certain amount of a foreign currency. In this way, whenever the Fund anticipates a decline in the value of a foreign currency against the U.S. dollar, the Fund can attempt to “lock in” the U.S. dollar value of some or all of the securities held in its portfolio that are denominated in that currency. By purchasing currency futures, the Fund can establish the number of dollars it will be required to pay for a specified amount of a foreign currency in a future month. Thus, if the Fund intends to buy securities in the future and expects the U.S. dollar to decline against the relevant foreign currency during the period before the purchase is effected, the Fund can attempt to “lock in” the price in U.S. dollars of the securities it intends to acquire.

The purchase of options on currency futures will allow the Fund, for the price of the premium and related transaction costs it must pay for the option, to decide whether or not to buy (in the case of a call option) or to sell (in the case of a put option) a futures contract at a specified price at any time during the period before the option expires. If the Investment Adviser, in purchasing an option, has been correct in its judgment concerning the direction in which the price of a foreign currency would move against the U.S. dollar, the Fund may exercise the option and thereby take a futures position to hedge against the risk it had correctly anticipated or close out the option position at a gain that will offset, to some extent, currency exchange losses otherwise suffered by

86

The Gabelli Convertible and Income Securities Fund Inc.

Additional Fund Information (Continued) (Unaudited)

the Fund. If exchange rates move in a way the Fund did not anticipate, however, the Fund will have incurred the expense of the option without obtaining the expected benefit; any such movement in exchange rates may also thereby reduce rather than enhance the Fund’s profits on its underlying securities transactions.

Securities Index Futures Contracts and Options Thereon. Purchases or sales of securities index futures contracts are used for hedging purposes to attempt to protect the Fund’s current or intended investments from broad fluctuations in stock or bond prices. For example, the Fund may sell securities index futures contracts in anticipation of or during a market decline to attempt to offset the decrease in market value of the Fund’s securities portfolio that might otherwise result. If such decline occurs, the loss in value of portfolio securities may be offset, in whole or part, by gains on the futures position. When the Fund is not fully invested in the securities market and anticipates a significant market advance, it may purchase securities index futures contracts in order to gain rapid market exposure that may, in part or entirely, offset increases in the cost of securities that the Fund intends to purchase. As such purchases are made, the corresponding positions in securities index futures contracts will be closed out. The Fund may write put and call options on securities index futures contracts for hedging purposes.

Loans of Portfolio Securities. Consistent with applicable regulatory requirements and the Fund’s investment restrictions, the Fund may lend its portfolio securities to securities broker-dealers or financial institutions, provided that such loans are callable at any time by the Fund (subject to notice provisions described below), and are at all times collateralized by cash or cash equivalents, which are to be maintained at all times in an amount equal to at least 100% of the market value, determined daily, of the loaned securities. The advantage of such loans is that the Fund continues to receive the income on the loaned securities while at the same time earning interest on the cash amounts deposited as collateral, which will be invested in short term highly liquid obligations. The Fund will not lend its portfolio securities if such loans are not permitted by the laws or regulations of any state in which its shares are qualified for sale. The Fund’s loans of portfolio securities will be collateralized in accordance with applicable regulatory requirements, which means that “cash equivalents” accepted as collateral will be limited to securities issued or guaranteed by the U.S. Government or its agencies or instrumentalities or irrevocable letters of credit issued by a bank (other than the Fund’s bank lending agent, if any, or a borrower of the Fund’s portfolio securities or any affiliate of such bank or borrower) which qualifies as a custodian bank for an investment company under the 1940 Act, and no loan will cause the value of all loaned securities to exceed 20% of the value of the Fund’s total assets. The Fund’s ability to lend portfolio securities may be limited by rating agency guidelines (if any).

A loan may generally be terminated by the borrower on one business day’s notice, or by the Fund at any time thereby requiring the borrower to redeliver the borrowed securities within the normal and customary settlement time for securities transactions. If the borrower fails to deliver the loaned securities within the normal and customary settlement time for securities transactions, the Fund could use the collateral to replace the securities while holding the borrower liable for any excess of replacement cost over the value of the collateral pledged by the borrower. As with any extensions of credit, there are risks of delay in recovery and in some cases even loss of rights in the collateral should the borrower of the securities violate the terms of the loan or fail financially. However, these loans of portfolio securities will only be made to firms deemed by the Investment Adviser to be creditworthy and when the income which can be earned from such loans justifies the attendant risks. The Board will oversee the creditworthiness of the contracting parties on an ongoing basis. Upon termination of the loan,

87

The Gabelli Convertible and Income Securities Fund Inc.

Additional Fund Information (Continued) (Unaudited)

the borrower is required to return the securities to the Fund. Any gain or loss in the market price during the loan period would inure to the Fund.

The risks associated with loans of portfolio securities are substantially similar to those associated with repurchase agreements. Thus, if the counter party to the loan petitions for bankruptcy or becomes subject to the United States Bankruptcy Code, the law regarding the rights of the Fund is unsettled. As a result, under extreme circumstances, there may be a restriction on the Fund’s ability to sell the collateral and the Fund would suffer a loss. Moreover, because the Fund will reinvest any cash collateral it receives, as described above, the Fund is subject to the risk that the value of the investments it makes will decline and result in losses to the Fund. These losses, in extreme circumstances such as the 2007-2009 financial crisis, could be substantial and have a significant adverse impact on the Fund and its shareholders.

When voting or consent rights which accompany loaned securities pass to the borrower, the Fund will follow the policy of calling the loaned securities, to be delivered within one day after notice, to permit the exercise of such rights if the matters involved would have a material effect on the Fund’s investment in such loaned securities. The Fund will pay reasonable finder’s, administrative and custodial fees in connection with a loan of its securities, and may also pay fees to one or more securities lending agents and/or pay other fees or rebates to borrowers.

Additional Risks of Foreign Options, Futures Contracts, Options on Futures Contracts and Forward Contracts. Options, futures contracts and options thereon and forward contracts on securities and currencies may be traded on foreign exchanges. Such transactions may not be regulated as effectively as similar transactions in the United States, may not involve a clearing mechanism and related guarantees, and are subject to the risk of governmental actions affecting trading in, or the prices of, foreign securities. The value of such positions also could be adversely affected by (i) other complex foreign political, legal and economic factors, (ii) lesser availability than in the U.S. of data on which to make trading decisions, (iii) delays in the Fund’s ability to act upon economic events occurring in the foreign markets during non-business hours in the United States, (iv) the imposition of different exercise and settlement terms and procedures and margin requirements than in the United States and (v) lesser trading volume.

Exchanges on which options, futures and options on futures are traded may impose limits on the positions that the Fund may take in certain circumstances.

Repurchase Agreements. The Fund may enter into repurchase agreements as set forth herein. A repurchase agreement is an instrument under which the purchaser, i.e., the Fund, acquires a debt security and the seller agrees, at the time of the sale, to repurchase the obligation at a mutually agreed upon time and price, thereby determining the yield during the purchaser’s holding period. This results in a fixed rate of return insulated from market fluctuations during such period. The underlying securities are ordinarily U.S. Treasury or other government obligations or high quality money market instruments. The Fund will require that the value of such underlying securities, together with any other collateral held by the Fund, always equals or exceeds the amount of the repurchase obligations of the counter party. The Fund’s risk is primarily that, if the seller defaults, the proceeds from the disposition of the underlying securities and other collateral for the seller’s obligation are less than the repurchase price. If the seller becomes insolvent, the Fund might be delayed in or prevented from selling the collateral. In the event of a default or bankruptcy by a seller, the Fund will promptly seek to liquidate

88

The Gabelli Convertible and Income Securities Fund Inc.

Additional Fund Information (Continued) (Unaudited)

the collateral. To the extent that the proceeds from any sale of such collateral upon a default in the obligation to repurchase are less than the repurchase price, the Fund will experience a loss.

If the financial institution which is a party to the repurchase agreement petitions for bankruptcy or becomes subject to the United States Bankruptcy Code, the law regarding the rights of the Fund is unsettled. As a result, under extreme circumstances, there may be a restriction on the Fund’s ability to sell the collateral and the Fund would suffer a loss.

Additional Risk Relating to Derivative Investments

Special Risk Considerations Relating to Futures and Options Thereon. The Fund’s ability to establish and close out positions in futures contracts and options thereon will be subject to the development and maintenance of liquid markets. Although the Fund generally will purchase or sell only those futures contracts and options thereon for which there appears to be a liquid market, there is no assurance that a liquid market on an exchange will exist for any particular futures contract or option thereon at any particular time. In the event no liquid market exists for a particular futures contract or option thereon in which the Fund maintains a position, it will not be possible to effect a closing transaction in that contract or to do so at a satisfactory price and the Fund would have to either make or take delivery under the futures contract or, in the case of a written option, wait to sell the underlying securities until the option expires or is exercised or, in the case of a purchased option, exercise the option. In the case of a futures contract or an option thereon which the Fund has written and which the Fund is unable to close, the Fund would be required to maintain margin deposits on the futures contract or option thereon and to make variation margin payments until the contract is closed.

Successful use of futures contracts and options thereon and forward contracts by the Fund is subject to the ability of the Investment Adviser to predict correctly movements in the direction of interest and foreign currency rates. If the Investment Adviser’s expectations are not met, the Fund will be in a worse position than if a hedging strategy had not been pursued. For example, if the Fund has hedged against the possibility of an increase in interest rates that would adversely affect the price of securities in its portfolio and the price of such securities increases instead, the Fund will lose part or all of the benefit of the increased value of its securities because it will have offsetting losses in its futures positions. In addition, in such situations, if the Fund has insufficient cash to meet daily variation margin requirements, it may have to sell securities to meet the requirements. These sales may be, but will not necessarily be, at increased prices which reflect the rising market. The Fund may have to sell securities at a time when it is disadvantageous to do so.

INVESTMENT RESTRICTIONS

Fundamental Restrictions and Policies

The Fund operates under the following restrictions that constitute fundamental policies under the 1940 Act and that, except as otherwise noted, cannot be changed without the affirmative vote of the holders of a majority of the outstanding voting securities of the Fund voting together as a single class (which for this purpose and under

89

The Gabelli Convertible and Income Securities Fund Inc.

Additional Fund Information (Continued) (Unaudited)

the 1940 Act means the lesser of (i) 67% of the shares represented at a meeting at which more than 50% of the outstanding shares are represented or (ii) more than 50% of the outstanding shares). In addition, pursuant to the Fund’s Series E Preferred Articles Supplementary, the affirmative vote of the holders of a majority of the outstanding preferred shares of the Fund voting as a separate class (which for this purpose and under the 1940 Act means the lesser of (i) 67% of the preferred shares, as a single class, represented at a meeting at which more than 50% of the Fund’s outstanding preferred shares are represented or (ii) more than 50% of the outstanding preferred shares), is also required to change a fundamental policy. Except as otherwise noted, all percentage limitations set forth below apply immediately after a purchase or initial investment and any subsequent change in any applicable percentage resulting from market fluctuations does not require any action. The Fund may not:

| ● | purchase the securities of any one issuer, other than the United States government or any of its agencies or instrumentalities, if immediately after such purchase more than 5% of the value of its total assets would be invested in such issuer or the Fund would own more than 10% of the outstanding voting securities of such issuer, except that up to 25% of the value of the Fund’s total assets may be invested without regard to such 5% and 10% limitations;

| ● | purchase or otherwise acquire real estate or interests therein, although the Fund may purchase securities of issuers which engage in real estate operations and securities secured by real estate or interests therein;

| ● | purchase or otherwise acquire or sell commodities or commodity contracts except that the Fund may purchase or sell financial futures contracts and related options thereon;

| ● | purchase oil, gas or other mineral leases, rights or royalty contracts, or exploration or development programs, except that the Fund may invest in the securities of companies which operate, invest in, or sponsor such programs;

| ● | purchase securities of other investment companies, except in connection with a merger, consolidation, reorganization or acquisition of assets, except that the Fund reserves the right to invest up to 5% of its total assets in not more than 3% of the securities of any one investment company including small business investment companies or invest up to 10% of its total assets in the securities of investment companies, nor make any such investments other than through purchases in the open market where to the best information of the Fund no commission or profit to a sponsor or dealer (other than the customary broker’s commission) results from such purchase;

| ● | borrow money, except to the extent permitted by applicable law;

| ● | issue senior securities except to the extent permitted by applicable law;

| ● | make loans of money or securities, except: (a) that the Fund may engage in repurchase agreements as set forth in the Prospectus and (b) the Fund may lend its portfolio securities consistent with applicable regulatory requirements and as set forth in the Prospectus;

| ● | make short sales of securities or maintain a short position, unless at all times when a short position is open, it either owns an equal amount of such securities or owns securities which, without payment of

90

The Gabelli Convertible and Income Securities Fund Inc.

any further consideration, are convertible into or exchangeable for securities of the same issue as, and equal in amount to, the securities sold short;

| ● | engage in the underwriting of securities, except insofar as the Fund may be deemed an underwriter under the Securities Act of 1933, as amended, in disposing of a portfolio security;

| ● | invest for the purpose of exercising control or management of any other issuer; or

| ● | invest more than 25% of the value of its total assets in any one industry.

If a percentage restriction is adhered to at the time of investment, a later increase or decrease in percentage resulting from a change in values of portfolio securities or amount of total or net assets will not be considered a violation of any of the foregoing restrictions.

The Fund may become subject to rating agency guidelines that are more limiting than its current investment restrictions in order to obtain and maintain a desired rating on its preferred shares, if any.

The Fund’s investment objective is a fundamental policy. Except as expressly stated above, none of the Fund’s other policies is fundamental, and each may be modified by the Board without shareholder approval.

The 1940 Act permits the Fund to borrow money in amounts of up to one-third of the Fund’s total assets from banks for any purpose, and to borrow up to 5% of the Fund’s total assets from banks or other lenders for temporary purposes. The Fund’s total assets include the amounts being borrowed. To limit the risks attendant to borrowing, the 1940 Act requires the Fund to maintain at all times an “asset coverage” of at least 300% of the amount of its borrowings. Asset coverage means the ratio that the value of the Fund’s total assets (including amounts borrowed), minus liabilities other than borrowings, bears to the aggregate amount of all borrowings. Borrowing money to increase portfolio holdings is known as “leveraging.” The investment restriction regarding borrowing money, described above, will be interpreted to permit the Fund to (a) engage in securities lending in accordance with the SEC staff guidance and interpretations and (b) settle securities transactions within the ordinary settlement cycle for such transactions.

The 1940 Act permits the Fund to issue senior securities (which may be stock, such as preferred shares, and/or securities representing debt, such as notes) only if immediately after such issuance the value of the Fund’s total assets, less certain ordinary course liabilities, exceeds 300% of the amount of the debt outstanding and exceeds 200% of the amount of preferred shares (measured by liquidation value) and debt outstanding, which is referred to as the “asset coverage” required by the 1940 Act. The 1940 Act also generally restricts the Fund from declaring cash distributions on, or repurchasing, common or preferred shares unless outstanding debt securities have an asset coverage of 300% (200% in the case of declaring distributions on preferred shares), or from declaring cash distributions on, or repurchasing, common shares unless preferred shares have an asset coverage of 200% (in each case, after giving effect to such distribution or repurchase).

General

The Fund’s Board has overall responsibility for the management of the Fund. The Board decides upon matters of general policy and reviews the actions of the Investment Adviser, Gabelli Funds, LLC, One Corporate Center, Rye, New York 10580-1422, and the Sub-Administrator (as defined below). Pursuant to an investment advisory agreement with the Fund, the Investment Adviser, under the supervision of the Fund’s Board, provides a continuous investment program for the Fund’s portfolio; provides investment research and makes and executes recommendations for the purchase and sale of securities; and provides all facilities and personnel, including officers required for its administrative management and pays the compensation of all officers and directors of the Fund who are officers or employees of the Investment Adviser or its affiliates. As compensation for its services rendered and the related expenses borne by the Investment Adviser, the Fund pays the Investment Adviser a fee, computed daily and payable monthly, equal, on an annual basis, to 1.00% of the Fund’s average daily net assets including the liquidation value of preferred shares. Net assets does not include amounts attributable to liabilities constituting indebtedness.

Because the investment advisory fees are based on a percentage of total assets, which includes assets attributable to the Fund’s use of leverage and assets from derivative transactions, the Investment Adviser may have a conflict of interest in the input it provides to the Board regarding whether to use or increase the Fund’s use of leverage and/or derivative transactions. The Board bases its decision, with input from the Investment Adviser, regarding whether and how much leverage to use for the Fund on its assessment of whether such use of leverage is in the best interest of the Fund. The Board seeks to manage the Investment Adviser’s potential conflict of interest by retaining the final decision on these matters and by periodically reviewing the Fund’s performance and use of leverage.

The Investment Adviser

The Investment Adviser is a New York limited liability company which serves as an investment adviser to registered investment companies with combined aggregate net assets of approximately $23.0 billion as of September 30, 2025. The Investment Adviser is a registered investment adviser under the Investment Advisers Act of 1940, as amended, and is a wholly owned subsidiary of GAMCO Investors, Inc. (“GAMI”). Mr. Gabelli owns a majority of the stock of GGCP, Inc. (“GGCP”) which holds a majority of the capital stock and voting power of GAMI. The Investment Adviser has several affiliates that provide investment advisory services: GAMCO Asset Management Inc., a wholly owned subsidiary of GAMI, acts as investment adviser for individuals, pension trusts, profit sharing trusts, and endowments, and as a sub-adviser to certain third party investment funds, which include registered investment companies, having assets under management of approximately of $12.0 billion as of September 30, 2025; Teton Advisors, Inc., and its wholly owned investment adviser, Keeley Teton Advisers, LLC, with assets under management of approximately $540 million as of June 30, 2025, acts as investment adviser to The TETON Westwood Funds and separately managed accounts; and Gabelli & Company Investment Advisers, Inc. (formerly, Gabelli Securities, Inc.), a wholly owned subsidiary of Associated Capital Group, Inc. (“Associated Capital”), acts as investment adviser for certain alternative investment products, consisting primarily of risk arbitrage and merchant banking limited partnerships and offshore companies, with assets under management of approximately $1.4 billion as of September 30, 2025. Teton Advisors, Inc., was spun off by GAMI in March 2009 and is an affiliate of GAMI by virtue of Mr. Gabelli’s ownership of GGCP, the principal shareholder of Teton Advisors, Inc., as of September 30, 2025. Associated Capital was spun off from

97

The Gabelli Convertible and Income Securities Fund Inc.

Additional Fund Information (Continued) (Unaudited)

GAMI on November 30, 2015, and is an affiliate of GAMI by virtue of Mr. Gabelli’s ownership of GGCP, the principal shareholder of Associated Capital.

A discussion regarding the basis for the Fund’s Board approval of the Investment Advisory Agreement with the Investment Adviser is available in this Annual Report.

Payment of Expenses

The Investment Adviser is obligated to pay expenses associated with providing the services contemplated by the Investment Advisory Agreement including compensation of and office space for its officers and employees connected with investment and economic research, trading and investment management and administration of the Fund (but excluding costs associated with the calculation of the net asset value and allocated costs of the chief compliance officer function and officers of the Fund who are employed by the Fund and are not employed by the Investment Adviser although such officers may receive incentive-based variable compensation from affiliates of the Investment Adviser), as well as the fees of all Directors of the Fund who are officers or employees of the Investment Adviser or its affiliates.

In addition to the fees of the Investment Adviser, the Fund, and indirectly the holders of its common shares, is responsible for the payment of all its other expenses incurred in the operation of the Fund, which include, among other things, underwriting compensation and reimbursements in connection with sales of the Fund’s securities, expenses for legal and the Fund’s independent registered public accounting firm’s services, stock exchange listing fees and expenses, costs of printing proxies, share certificates and shareholder reports, charges of the Fund’s Custodian, any sub-custodian and any transfer agent and distribution disbursing agent, expenses in connection with the Automatic Dividend Reinvestment Plan and the Voluntary Cash Purchase Plan, SEC fees and preparation of filings with the SEC, fees and expenses of Directors who are not officers or employees of the Investment Adviser or its affiliates, accounting and printing costs, the Fund’s pro rata portion of membership fees in trade organizations, compensation and other expenses of officers and employees of the Fund (including, but not limited to, the Chief Compliance Officer, Vice President and Ombudsman) as approved by the Fund’s Directors, fidelity bond coverage for the Fund’s officers and employees, Directors’ and officers’ errors and omissions insurance coverage, interest, brokerage costs, taxes, expenses of qualifying the Fund’s shares for sale in various states, expenses of personnel performing shareholder servicing functions, rating agency fees, organizational expenses, litigation and other extraordinary or non-recurring expenses and other expenses properly payable by the Fund.

Selection of Securities Brokers

The Investment Advisory Agreement contains provisions relating to the selection of securities brokers to effect the portfolio transactions of the Fund. Under those provisions, the Investment Adviser may (i) direct Fund portfolio brokerage to G.research, LLC (“G.research”), an affiliate of the Investment Adviser, or to other broker-dealer affiliates of the Investment Adviser and (ii) pay commissions to brokers other than G.research that are higher than might be charged by another qualified broker to obtain brokerage and/or research services considered by the Investment Adviser to be useful or desirable for its investment management of the Fund and/or its other investment advisory accounts or those of any investment adviser affiliated with it.

Portfolio Managers

Mario J. Gabelli, CFA, is Chairman, Chief Executive Officer, and Chief Investment Officer—Value Portfolios of GAMCO Investors, Inc. that he founded in 1977 and Chief Investment Officer—Value Portfolios of Gabelli Funds, LLC and GAMCO Asset Management Inc. He is also Executive Chairman of Associated Capital Group, Inc. Mr. Gabelli is a summa cum laude graduate of Fordham University, and holds an M.B.A. degree from Columbia Business School and Honorary Doctorates from Fordham University and Roger Williams University.

James A. Dinsmore, CFA, joined Gabelli Funds, LLC in 2015. He currently serves as a portfolio manager of Gabelli Funds, LLC and manages several funds within the Gabelli/GAMCO Funds Complex. Mr. Dinsmore received a B.A. in Economics from Cornell University and an M.B.A. degree from Rutgers University.

Non-Resident Directors

Anthonie C. van Ekris and John Birch, Directors of the Fund, reside outside of the United States and all or a significant portion of their assets are located outside the United States. Messrs. van Ekris and Birch do not have an authorized agent in the United States to receive service of process. As a result, it may not be possible for investors to effect service of process within the United States or to enforce against either of them in U.S. court judgments predicated upon the civil liability provisions of U.S. securities laws. It may also not be possible to enforce against Messrs. van Ekris and Birch in foreign courts judgments of U.S. courts or liabilities in original actions predicated upon civil liability provisions of the United States. Further, it is not certain that such courts would enforce, in an original action, liabilities against Messrs. van Ekris and Birch predicated solely on U.S. federal securities laws.

Sub-Administrator

The Investment Adviser has entered into a sub-administration agreement with The Bank of New York Mellon (the “Sub-Administrator”) pursuant to which the Sub-Administrator provides certain administrative services necessary for the Fund’s operations which do not include the investment and portfolio management services provided by the Investment Adviser. For these services and the related expenses borne by the Sub-Administrator, the Investment Adviser pays an annual fee based on the value of the aggregate average daily net assets of all funds under its administration managed by the Investment Adviser, GAMCO and Teton Advisors, Inc. as follows: 0.0275%—first $10 billion, 0.0125%—exceeding $10 billion but less than $15 billion, 0.01%—over $15 billion but less than $20 billion and 0.008% over $20 billion. The Sub-Administrator has its principal office at 760 Moore Road, King of Prussia, Pennsylvania 19406.

NET ASSET VALUE

The net asset value of the Fund’s shares is computed based on the market value of the securities it holds and is determined daily as of the close of the regular trading day on the NYSE. For purposes of determining the Fund’s net asset value per share, 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 mean of the closing bid and asked

99

The Gabelli Convertible and Income Securities Fund Inc.

Additional Fund Information (Continued) (Unaudited)

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 ask prices are quoted on such day, the security will be valued based on written or standing instructions from the Investment Adviser, which has been appointed Valuation Designee pursuant to Rule 2a-5 under the 1940 Act (“Rule 2a-5”) by the Board. 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 Valuation Designee.

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 by the Valuation Designee under procedures adopted pursuant to Rule 2a-5 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 instruments with remaining maturities of 60 days or less that are not credit impaired are valued at amortized cost, unless the Valuation Designee determines such amount does not reflect the securities’ fair value, in which case these securities will be fair valued as determined by the Valuation Designee. Debt instruments having a maturity greater than 60 days 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 security is valued using the closing bid price. Futures contracts are valued at the closing settlement price of the exchange or board of trade on which the applicable contract is traded.

Options are valued using market quotations. When market quotations are not readily available, options are valued from broker quotes. In limited circumstances when neither market quotations nor broker quotes are readily available, options are valued using a Black Scholes model.

Securities and assets for which market quotations are not readily available are fair valued as determined by the Valuation Designee. 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 to the valuation and changes in valuation of similar securities, including a comparison of foreign securities to the equivalent U.S. dollar value ADR 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 Fund obtains valuations on the basis of prices provided by a pricing service monitored by the Valuation Designee. All other investment assets, including restricted and not readily marketable securities, are valued in good faith at fair value by the Valuation Designee under procedures adopted pursuant to Rule 2a-5.

In addition, whenever developments in one or more securities markets after the close of the principal markets for one or more portfolio securities and before the time as of which the Fund determines its net asset value would, if such developments had been reflected in such principal markets, likely have more than a minimal effect on the Fund’s net asset value per share, the Valuation Designee may fair value such portfolio securities based on available market information as of the time the Fund determines its net asset value.

NYSE Closings. The holidays (as observed) on which the NYSE is closed, and therefore days upon which shareholders will not be able to purchase or sell common shares currently are: New Year’s Day, Martin Luther King, Jr. Day, Presidents’ Day, Good Friday, Memorial Day, Juneteenth National Independence Day, Independence Day, Labor Day, Thanksgiving Day, and Christmas Day, and on the preceding Friday or subsequent Monday when a holiday falls on a Saturday or Sunday, respectively.

Control Share Acquisitions

On February 16, 2023 the Fund elected, by resolution unanimously adopted by the Board of Directors of the Fund in accordance with Section 3-702(c)(4) of the MGCL, to be subject to the Maryland Control Share Acquisition Act (the “Control Share Act”), effective immediately. The Control Share Act only applies to acquisitions of Fund shares on or after February 16, 2023.

Under the MGCL, the Control Share Act provides that a holder of control shares of a Maryland corporation acquired in a control share acquisition has no voting rights with respect to those shares except to the extent approved by a vote of two-thirds of the votes entitled to be cast on the matter. Shares owned by the acquiror, by officers or by directors who are employees of the corporation are excluded from shares entitled to vote on the matter. Control shares are voting shares of stock which, if aggregated with all other shares of stock owned by the acquiror or in respect of which the acquiror is able to exercise or direct the exercise of voting power (except solely by virtue of a revocable proxy), would entitle the acquiror to exercise voting power in electing directors within one of the following ranges of voting power:

| ● | one-tenth or more but less than one-third;
| ● | one-third or more but less than a majority; or
| ● | a majority or more of all voting power.

The requisite shareholder approval must be obtained each time an acquiror crosses one of the thresholds of voting power set forth above. Control shares do not include shares the acquiring person is then entitled to vote as a result of having previously obtained shareholder approval. A control share acquisition means the acquisition of issued and outstanding control shares, subject to certain exceptions.

A person who has made or proposes to make a control share acquisition may compel the board of directors of the corporation to call a special meeting of shareholders to be held within 50 days of demand to consider the voting rights of the shares. The right to compel the calling of a special meeting is subject to the satisfaction of certain conditions, including an undertaking to pay the expenses of the meeting. If no request for a meeting is made, the corporation may itself present the question at any shareholders meeting.

If voting rights are not approved at the meeting or if the acquiring person does not deliver an acquiring person statement as required by the statute, then the corporation may redeem for fair value any or all of the control shares, except those for which voting rights have previously been approved. The right of the corporation to redeem control shares is subject to certain conditions and limitations, including, compliance with the 1940 Act. Fair value is determined, without regard to the absence of voting rights for the control shares, as of the date of the last control share acquisition by the acquiror or of any meeting of shareholders at which the voting rights of the shares are considered and not approved. If voting rights for control shares are approved at a shareholders meeting and the acquiror becomes entitled to vote a majority of the shares entitled to vote, all other shareholders may exercise appraisal rights. The fair value of the shares as determined for purposes of appraisal rights may not be less than the highest price per share paid by the acquiror in the control share acquisition. However, the Bylaws provide that no shareholder shall be entitled to exercise appraisal rights under the Control Share Act.

In connection with the Fund’s election to be subject to the Control Share Act, the Fund’s Board of Directors adopted resolutions and amended the Fund’s Bylaws such that the Control Share Act does not apply (a) to

101

The Gabelli Convertible and Income Securities Fund Inc.

Additional Fund Information (Continued) (Unaudited)

shares of any class or series of stock of the Fund other than common stock, (b) to any acquisition by Mario J. Gabelli, or any affiliates or associates, therof, of shares of stock of the Fund, or (c) to shares of stock of the Fund in a control share acquisition if, prior to the acquisition, the person obtains approval of the Board of Directors exempting the acquisition from the Control Share Act. In addition, to the extent that any provision of the Control Share Act is determined to be inconsistent with the 1940 Act, then any provision shall not apply.

In connection with electing to be subject to the Control Share Act, the Board of Director of the Fund determined that such election and the implementation thereof in the Fund’s Bylaws as described above, including providing that the Control Share Act does not apply to certain transactions, is in the best interests of the Fund and its shareholders. The Fund should not be viewed as a vehicle for trading purposes. It is designed primarily for risk-tolerant long-term investors.

The foregoing is only a summary of the material term of the Control Share Act. Shareholders should consult their own counsel with respect to the application of the Control Share Act to any particular circumstance. Some uncertainty around the general application under the 1940 Act of state control share statutes exists as a result of recent court decisions which have held that control share provisions in funds’ governing documents are not consistent with the 1940 Act. Additionally, in some circumstances uncertainty may also exist in how to enforce the control share restrictions contained in state control share statutes against beneficial owners who hold their shares through financial intermediaries.

The limitations of the Control Share Act described above could have the effect of depriving shareholders of an opportunity to sell their shares at a premium over prevailing market prices by discouraging a third party from seeking to obtain control over the Fund and may reduce market demand for the Fund’s common stock trade at a discount to net asset value and increasing the amount of any such discount.

The provisions of the Governing Documents and Maryland law described above could have the effect of depriving the owners of stock in the Fund of opportunities to sell their shares at a premium over prevailing market prices by discouraging a third party from seeking to obtain control of the Fund in a tender offer or similar transaction. The overall effect of these provisions may render more difficult the accomplishment of a merger or the assumption of control by a principal shareholder.

102

AUTOMATIC DIVIDEND REINVESTMENT

AND VOLUNTARY CASH PURCHASE PLANS

Under the Fund’s Automatic Dividend Reinvestment Plan and Voluntary Cash Purchase Plan (the “Plan”), a shareholder whose shares of common stock are registered in his or her own name will have all distributions reinvested automatically by Computershare Trust Company, N.A. (“Computershare”), which is an agent under the Plan, unless the shareholder elects to receive cash. Distributions with respect to shares registered in the name of a broker-dealer or other nominee (that is, in “street name”) will be reinvested by the broker or nominee in additional shares under the Plan, unless the service is not provided by the broker or nominee or the shareholder elects to receive distributions in cash. Investors who own shares of common stock registered in street name should consult their broker-dealers for details regarding reinvestment. All distributions to investors who do not participate in the Plan will be paid by check mailed directly to the record holder by Computershare as dividend-disbursing agent.

Enrollment in the Plan

It is the policy of The Gabelli Convertible and Income Securities Fund (the “Fund”) to automatically reinvest dividends payable to common shareholders. As a “registered” shareholder you automatically become a participant in the Fund’s Automatic Dividend Reinvestment Plan (the “Plan”). The Plan authorizes the Fund to credit common shares to participants upon an income dividend or a capital gains distribution regardless of whether the shares are trading at a discount or a premium to net asset value. All distributions to shareholders whose shares are registered in their own names will be automatically reinvested pursuant to the Plan in additional shares of the Fund. Plan participants may send their common shares certificates to Computershare Trust Company, N.A. (“Computershare”) to be held in their dividend reinvestment account. Registered shareholders wishing to receive their distributions in cash may submit this request through the Internet, by telephone or in writing to:

The Gabelli Convertible and Income Securities Fund

c/o Computershare

P.O. Box 43006

Providence, RI 02940-3006

Telephone: (800) 336-6983

Website: www.computershare.com/investor

Shareholders requesting this cash election must include the shareholder’s name and address as they appear on the Fund’s records. Shareholders with additional questions regarding the Plan or requesting a copy of the terms of the Plan, may contact Computershare at the website or telephone number above.

If your shares are held in the name of a broker, bank, or nominee, you should contact such institution. If such institution is not participating in the Plan, your account will be credited with a cash dividend. In order to participate in the Plan through such institution, it may be necessary for you to have your shares taken out of “street name” and re-registered in your own name. Once registered in your own name your distributions will be automatically reinvested. Certain brokers participate in the Plan. Shareholders holding shares in “street name” at participating institutions will have dividends automatically reinvested. Shareholders wishing a cash dividend at such institution must contact their broker to make this change.

The number of shares of common stocks distributed to participants in the Plan in lieu of cash dividends is determined in the following manner. Under the Plan, whenever the market price of the Fund’s common shares is equal to or exceeds net asset value at the time shares are valued for purposes of determining the number of shares equivalent to the cash dividends or capital gains distribution, participants are issued shares of common stocks valued at the greater of (i) the net asset value as most recently determined or (ii) 95% of the then current market price of the Fund’s common stocks. The valuation date is the dividend or distribution payment date or, if that date is not a New York Stock Exchange (“NYSE”) trading day, the next trading day. If the net asset value of the common stocks at the time of valuation exceeds the market price of the common stocks, participants will receive shares from the Fund valued at market price. If the Fund should declare a dividend or capital gains distribution payable only in cash, Computershare will buy shares of common stocks in the open market, or on the NYSE or elsewhere, for the participants’ accounts, except that Computershare will endeavor to terminate purchases in the open market and cause the Fund to issue shares at net asset value if, following the commencement of such purchases, the market value of the common stocks exceeds the then current net asset value.

The automatic reinvestment of dividends and capital gains distributions will not relieve participants of any income tax which may be payable on such distributions. A participant in the Plan will be treated for federal income tax purposes as having received, on a dividend payment date, a dividend or distribution in an amount equal to the cash the participant could have received instead of shares.

AUTOMATIC DIVIDEND REINVESTMENT

AND VOLUNTARY CASH PURCHASE PLANS

(Continued)

Voluntary Cash Purchase Plan

The Voluntary Cash Purchase Plan is yet another vehicle for our shareholders to increase their investment in the Fund. In order to participate in the Voluntary Cash Purchase Plan, shareholders must have their shares registered in their own name.

Participants in the Voluntary Cash Purchase Plan have the option of making additional cash payments to Computershare for investments in the Fund’s shares at the then current market price. shareholders may send an amount from $250 to $10,000. Computershare will use these funds to purchase shares in the open market on or about the 1st and 15th of each month. Computershare will charge each shareholder who participates $0.75, plus a per share fee (currently $0.02 per share). Per share fees include any applicable brokerage commissions Computershare is required to pay and fees for such purchases are expected to be less than the usual fees for such transactions. It is suggested that any voluntary cash payments be sent to Computershare, P.O. Box 6006, Carol Stream, IL 60197-6006 such that Computershare receives such payments approximately three business days before the 1st and 15th of the month. Funds not received at least three business days before the investment date shall be held for investment until the next purchase date. Computershare will wait up to three business days after receipt of a check to ensure it receives good funds and will then seek to purchase shares for voluntary cash payments on the voluntary cash payment date. A payment may be withdrawn without charge if notice is received by Computershare at least two business days before such payment is to be invested.

Shareholders wishing to liquidate shares held at Computershare may do so through the Internet, in writing or by telephone to the above-mentioned website, address or telephone number. Include in your request your name, address, and account number. Computershare will sell such shares through a broker-dealer selected by Computershare within 5 business days of receipt of the request. The sale price will equal the weighted average price of all shares sold through the Plan on the day of the sale, less applicable fees. Participants should note that Computershare is unable to accept instructions to sell on a specific date or at a specific price. The cost to liquidate shares is $2.50 per transaction as well as the per share fee (currently $0.10 per share) Per share fees include any applicable brokerage commissions Computershare is required to pay and are expected to be less than the usual fees for such transactions.

More information regarding the Automatic Dividend Reinvestment Plan and Voluntary Cash Purchase Plan is available by calling (914) 921-5070 or by writing directly to the Fund.

The Fund reserves the right to amend or terminate the Plan as applied to any voluntary cash payments made and any dividend or distribution paid subsequent to written notice of the change sent to the members of the Plan at least 30 days before the record date for such dividend or distribution. The Plan also may be amended or terminated by Computershare on at least 30 days written notice to participants in the Plan.

Corporate Dividends Received Deduction, Qualified Dividend Income, and U.S. Government Securities Income

For the fiscal year ended September 30, 2025, the Fund paid to common shareholder, 5.200% Series G Cumulative Preferred shareholders, and 5.200% Series H Cumulative Preferred shareholders ordinary income distributions totaling $0.3553, $0.506127, and $0.123064 per share, in 2025. The distribution of long term capital gains has been designated as a capital gain dividend by the Fund’s Board of Directors. For the fiscal period ended September 30, 2025, 6.63% of the ordinary dividend qualified for the dividends received deduction available to corporations, 6.87% of the ordinary income distribution was qualified dividend income, 9.67% of the ordinary income distribution was qualified interest income, and 83.36% of ordinary income distribution was qualified short term capital gain. The percentage of ordinary income dividends paid by the Fund during 2025 derived from U.S. Treasury securities was 1.87%. Such income is exempt from state and local tax in all states. However, many states, including New York and California, allow a tax exemption for a portion of the income earned only if a mutual fund has invested at least 50% of its assets at the end of each quarter of the Fund’s fiscal period in U.S. Government securities. The Fund did not meet this strict requirement in 2025. The percentage of U.S. Government securities held as of September 30, 2025 was 8.9%. Due to the diversity in state and local tax law, it is recommended that you consult your personal tax adviser as to the applicability of the information provided to your specific situation.

A copy of the Company’s Proxy Voting Policies and Procedures is attached herewith.

GAMCO INVESTORS, INC. AND AFFILIATES

The Voting of Proxies on Behalf of Clients

Rule 206(4)-6 under the Investment Advisers Act of 1940 and Rule 30b1-4 under the Investment Company Act of 1940 require investment advisers to adopt written policies and procedures governing the voting of proxies on behalf of their clients.

These procedures will be used by GAMCO Asset Management Inc., Gabelli Funds, LLC, Gabelli & Company Investment Advisers, Inc., and Teton Advisors, Inc. (collectively, the “Advisers”) to determine how to vote proxies relating to portfolio securities held by their clients, including the procedures that the Advisers use when a vote presents a conflict between the interests of the shareholders of an investment company managed by one of the Advisers, on the one hand, and those of the Advisers; the principal underwriter; or any affiliated person of the investment company, the Advisers, or the principal underwriter. These procedures will not apply where the Advisers do not have voting discretion or where the Advisers have agreed to with a client to vote the client’s proxies in accordance with specific guidelines or procedures supplied by the client (to the extent permitted by ERISA).

| I. | Proxy Voting Committee

The Proxy Voting Committee was originally formed in April 1989 for the purpose of formulating guidelines and reviewing proxy statements within the parameters set by the substantive proxy voting guidelines originally published in 1988 and updated periodically, a copy of which are appended as Exhibit A. The Committee will include representatives of Research, Administration, Legal, and the Advisers. Additional or replacement members of the Committee will be nominated by the Chairman and voted upon by the entire Committee.

Meetings are held on an as needed basis to form views on the manner in which the Advisers should vote proxies on behalf of their clients.

In general, the Director of Proxy Voting Services, using the Proxy Guidelines, and the analysts of GAMCO Investors, Inc. (“GAMI”), will determine how to vote on each issue. For non-controversial matters, the Director of Proxy Voting Services may vote the proxy if the vote is: (1) consistent with the recommendations of the issuer’s Board of Directors and not contrary to the Proxy Guidelines; (2) consistent with the recommendations of the issuer’s Board of Directors and is a non-controversial issue not covered by the Proxy Guidelines; or (3) the vote is contrary to the recommendations of the Board of Directors but is consistent with the Proxy Guidelines. In those instances, the Director of Proxy Voting Services or the Chairman of the Committee may sign and date the proxy statement indicating how each issue will be voted.

Not For Distribution

All matters identified by the Chairman of the Committee, the Director of Proxy Voting Services or the Legal Department as controversial, taking into account the recommendations of the analysts of GAMI, will be presented to the Proxy Voting Committee. If the Chairman of the Committee, the Director of Proxy Voting Services or the Legal Department has identified the matter as one that (1) is controversial; (2) would benefit from deliberation by the Proxy Voting Committee; or (3) may give rise to a conflict of interest between the Advisers and their clients, the Chairman of the Committee will initially determine what vote to recommend that the Advisers should cast and the matter will go before the Committee.

| A. | Conflicts of Interest.

The Advisers have implemented these proxy voting procedures in order to prevent conflicts of interest from influencing their proxy voting decisions. By following the Proxy Guidelines and the analysts of GAMI, the Advisers are able to avoid, wherever possible, the influence of potential conflicts of interest. Nevertheless, circumstances may arise in which one or more of the Advisers are faced with a conflict of interest or the appearance of a conflict of interest in connection with its vote. In general, a conflict of interest may arise when an Adviser knowingly does business with an issuer, and may appear to have a material conflict between its own interests and the interests of the shareholders of an investment company managed by one of the Advisers regarding how the proxy is to be voted. A conflict also may exist when an Adviser has actual knowledge of a material business arrangement between an issuer and an affiliate of the Adviser.

In practical terms, a conflict of interest may arise, for example, when a proxy is voted for a company that is a client of one of the Advisers, such as GAMCO Asset Management Inc. A conflict also may arise when a client of one of the Advisers has made a shareholder proposal in a proxy to be voted upon by one or more of the Advisers. The Director of Proxy Voting Services, together with the Legal Department, will scrutinize all proxies for these or other situations that may give rise to a conflict of interest with respect to the voting of proxies.

| B. | Operation of Proxy Voting Committee

For matters submitted to the Committee, each member of the Committee will receive, prior to the meeting, a copy of the proxy statement, a summary of any views provided by the Chief Investment Officer and any recommendations by GAMI analysts. The Chief Investment Officer or the GAMI analysts may be invited to present their viewpoints. If the Director of Proxy Voting Services or the Legal Department believe that the matter before the committee is one with respect to which a conflict of interest may exist between the Advisers and their clients, counsel may provide an opinion to the Committee concerning the conflict. If the matter is one in which the interests of the clients of one or more of the Advisers may diverge, counsel may so advise and the Committee may make different recommendations as to different clients. For any matters where the recommendation may trigger appraisal rights, counsel may provide an opinion concerning the likely risks and merits of such an appraisal action.

Not For Distribution

Each matter submitted to the Committee will be determined by the vote of a majority of the members present at the meeting. Should the vote concerning one or more recommendations be tied in a vote of the Committee, the Chairman of the Committee will cast the deciding vote. The Committee will notify the proxy department of its decisions and the proxies will be voted accordingly.

Although the Proxy Guidelines express the normal preferences for the voting of any shares not covered by a contrary investment guideline provided by the client, the Committee is not bound by the preferences set forth in the Proxy Guidelines and will review each matter on its own merits. The Advisers subscribe to Institutional Shareholder Services Inc (“ISS”) and Glass Lewis & Co., LLC (“Glass Lewis”), which supply current information on companies, matters being voted on, regulations, trends in proxy voting and information on corporate governance issues. The information provided by ISS and GL is for informational purposes only.

If the vote cast either by the analyst or as a result of the deliberations of the Proxy Voting Committee runs contrary to the recommendation of the Board of Directors of the issuer, the matter may be referred to legal counsel to determine whether an amendment to the most recently filed Schedule 13D is appropriate.

| II. | Social Issues and Other Client Guidelines

If a client has provided and the Advisers have accepted special instructions relating to the voting of proxies, they should be noted in the client’s account file and forwarded to the proxy department. This is the responsibility of the investment professional or sales assistant for the client. In accordance with Department of Labor guidelines, the Advisers’ policy is to vote on behalf of ERISA accounts in the best interest of the plan participants with regard to social issues that carry an economic impact. Where an account is not governed by ERISA, the Advisers will vote shares held on behalf of the client in a manner consistent with any individual investment/voting guidelines provided by the client. Otherwise the Advisers may abstain with respect to those shares.

Specific to the Gabelli SRI Fund and the Gabelli Love Our Planet & People ETF, the Proxy Voting Committee will rely on the advice of the portfolio managers of the Gabelli SRI Fund and the Gabelli Love Our Planet & People ETF to provide voting recommendations on the securities held in the portfolio.

A client may always request to vote their own proxies. Clients engaged in securities lending may make additional requests related to the voting of proxies. GAMI will consider those requests on a case-by-case basis and use best efforts to comply with the request.

Not For Distribution

| III. | Client Retention of Voting Rights

If a client chooses to retain the right to vote proxies or if there is any change in voting authority, the following should be notified by the investment professional or sales assistant for the client.

- Operations

- Proxy Department

- Investment professional assigned to the account

In the event that the Board of Directors (or a Committee thereof) of one or more of the investment companies managed by one of the Advisers has retained direct voting control over any security, the Proxy Voting Department will provide each Board Member (or Committee member) with a copy of the proxy statement together with any other relevant information.

| IV. | Proxies of Certain Non-U.S. Issuers

Proxy voting in certain countries requires “share-blocking.” Shareholders wishing to vote their proxies must deposit their shares shortly before the date of the meeting with a designated depository. During the period in which the shares are held with a depository, shares that will be voted at the meeting cannot be sold until the meeting has taken place and the shares are returned to the clients’ custodian. Absent a compelling reason to the contrary, the Advisers believe that the benefit to the client of exercising the vote is outweighed by the cost of voting and therefore, the Advisers will not typically vote the securities of non-U.S. issuers that require share-blocking.

In addition, voting proxies of issuers in non-U.S. markets may also give rise to a number of administrative issues or give rise to circumstances under which voting would impose a cost (real or implied) on its client which may cause the Advisers to abstain from voting such proxies. For example, the Advisers may receive the notices for shareholder meetings without adequate time to consider the proposals in the proxy or after the cut-off date for voting. Other markets require the Advisers to provide local agents with power of attorney prior to implementing their respective voting instructions on the proxy. Other markets may require disclosure of certain ownership information in excess of what is required to vote in the U.S. market. Although it is the Advisers’ policies to vote the proxies for its clients for which they have proxy voting authority, in the case of issuers in non-U.S. markets, we vote client proxies on a best efforts basis.

Not For Distribution

| V. | Voting Records

The Proxy Voting Department will retain a record of matters voted upon by the Advisers for their clients. The Advisers will supply information on how they voted a client’s proxy upon request from the client.

The complete voting records for each registered investment company (the “Fund”) that is managed by the Advisers will be filed on Form N-PX for the twelve months ended June 30th, no later than August 31st of each year. A description of the Fund’s proxy voting policies, procedures, and how the Fund voted proxies relating to portfolio securities is available without charge, upon request, by (i) calling 800-GABELLI (800-422-3554); (ii) writing to Gabelli Funds, LLC at One Corporate Center, Rye, NY 10580-1422; or (iii) visiting the SEC’s website at www.sec.gov.

The Advisers’ proxy voting records will be retained in compliance with Rule 204-2 under the Investment Advisers Act.

| VI. | Voting Procedures

1. Custodian banks, outside brokerage firms and clearing firms are responsible for forwarding proxies directly to the Advisers.

Proxies are received in one of two forms:

| ● | Shareholder Vote Instruction Forms (“VIFs”) - Issued by Broadridge Financial Solutions, Inc. (“Broadridge”). Broadridge is an outside service contracted by the various institutions to issue proxy materials.

| ● | Proxy cards which may be voted directly.

2. Upon receipt of the proxy, the number of shares each form represents is logged into the proxy system, electronically or manually, according to security.

3. Upon receipt of instructions from the proxy committee, the votes are cast and recorded for each account.

Records have been maintained on the ProxyEdge system.

ProxyEdge records include:

Security Name and CUSIP Number

Date and Type of Meeting (Annual, Special, Contest)

Directors’ Recommendation (if any)

How the Adviser voted for the client on item

Not For Distribution

4. VIFs are kept alphabetically by security. Records for the current proxy season are located in the Proxy Voting Department office. In preparation for the upcoming season, files are transferred to an offsite storage facility during January/February.

5. If a proxy card or VIF is received too late to be voted in the conventional matter, every attempt is made to vote including:

| ● | When a solicitor has been retained, the solicitor is called. At the solicitor’s direction, the proxy is faxed or sent electronically.

| ● | In some circumstances VIFs can be faxed or sent electronically to Broadridge up until the time of the meeting.

6. In the case of a proxy contest, records are maintained for each opposing entity.

7. Voting in Person

a) At times it may be necessary to vote the shares in person. In this case, a “legal proxy” is obtained in the following manner:

| ● | Banks and brokerage firms using the services at Broadridge:

Broadridge is notified that we wish to vote in person. Broadridge issues individual legal proxies and sends them back via email or overnight (or the Adviser can pay messenger charges). A lead-time of at least two weeks prior to the meeting is needed to do this. Alternatively, the procedures detailed below for banks not using Broadridge may be implemented.

| ● | Banks and brokerage firms issuing proxies directly:

The bank is called and/or faxed and a legal proxy is requested.

All legal proxies should appoint:

“Representative of [Adviser name] with full power of substitution.”

b) The legal proxies are given to the person attending the meeting along with the limited power of attorney.

Appendix A

Proxy Guidelines

PROXY VOTING GUIDELINES

General Policy Statement

It is the policy of GAMCO Investors, Inc, and its affiliated advisers (collectively “the Advisers”) to vote in the best economic interests of our clients. As we state in our Magna Carta of Shareholders Rights, established in May 1988, we are neither for nor against management. We are for shareholders.

At our first proxy committee meeting in 1989, it was decided that each proxy statement should be evaluated on its own merits within the framework first established by our Magna Carta of Shareholders Rights. The attached guidelines serve to enhance that broad framework.

We do not consider any issue routine. We take into consideration all of our research on the company, its directors, and their short and long-term goals for the company. In cases where issues that we generally do not approve of are combined with other issues, the negative aspects of the issues will be factored into the evaluation of the overall proposals but will not necessitate a vote in opposition to the overall proposals.

Board of Directors

We do not consider the election of the Board of Directors a routine issue. Each slate of directors is evaluated on a case-by-case basis.

Factors taken into consideration include:

● | Historical responsiveness to shareholders

This may include such areas as:

- Paying greenmail

- Failure to adopt shareholder resolutions receiving a majority of shareholder votes

| ● | Qualifications

| ● | Nominating committee in place

| ● | Number of outside directors on the board

| ● | Attendance at meetings

| ● | Overall performance

Not For Distribution

Selection of Auditors

In general, we support the Board of Directors’ recommendation for auditors.

Blank Check Preferred Stock

We oppose the issuance of blank check preferred stock.

Blank check preferred stock allows the company to issue stock and establish dividends, voting rights, etc. without further shareholder approval.

Classified Board

A classified board is one where the directors are divided into classes with overlapping terms. A different class is elected at each annual meeting.

While a classified board promotes continuity of directors facilitating long range planning, we feel directors should be accountable to shareholders on an annual basis. We will look at this proposal on a case-by-case basis taking into consideration the board’s historical responsiveness to the rights of shareholders.

Where a classified board is in place we will generally not support attempts to change to an annually elected board.

When an annually elected board is in place, we generally will not support attempts to classify the board.

Increase Authorized Common Stock

The request to increase the amount of outstanding shares is considered on a case-by-case basis.

Factors taken into consideration include:

| ● | Future use of additional shares

- Stock split

- Stock option or other executive compensation plan

- Finance growth of company/strengthen balance sheet

- Aid in restructuring

- Improve credit rating

- Implement a poison pill or other takeover defense

Not For Distribution

| ● | Amount of stock currently authorized but not yet issued or reserved for stock option plans

| ● | Amount of additional stock to be authorized and its dilutive effect

We will support this proposal if a detailed and verifiable plan for the use of the additional shares is contained in the proxy statement.

Confidential Ballot

We support the idea that a shareholder’s identity and vote should be treated with confidentiality.

However, we look at this issue on a case-by-case basis.

In order to promote confidentiality in the voting process, we endorse the use of independent Inspectors of Election.

Cumulative Voting

In general, we support cumulative voting.

Cumulative voting is a process by which a shareholder may multiply the number of directors being elected by the number of shares held on record date and cast the total number for one candidate or allocate the voting among two or more candidates.

Where cumulative voting is in place, we will vote against any proposal to rescind this shareholder right.

Cumulative voting may result in a minority block of stock gaining representation on the board. When a proposal is made to institute cumulative voting, the proposal will be reviewed on a case-by-case basis. While we feel that each board member should represent all shareholders, cumulative voting provides minority shareholders an opportunity to have their views represented.

Director Liability and Indemnification

We support efforts to attract the best possible directors by limiting the liability and increasing the indemnification of directors, except in the case of insider dealing.

Not For Distribution

Equal Access to the Proxy

The SEC’s rules provide for shareholder resolutions. However, the resolutions are limited in scope and there is a 500 word limit on proponents’ written arguments. Management has no such limitations. While we support equal access to the proxy, we would look at such variables as length of time required to respond, percentage of ownership, etc.

Fair Price Provisions

Charter provisions requiring a bidder to pay all shareholders a fair price are intended to prevent two-tier tender offers that may be abusive. Typically, these provisions do not apply to board-approved transactions.

We support fair price provisions because we feel all shareholders should be entitled to receive the same benefits.

Reviewed on a case-by-case basis.

Golden Parachutes

Golden parachutes are severance payments to top executives who are terminated or demoted after a takeover.

We support any proposal that would assure management of its own welfare so that they may continue to make decisions in the best interest of the company and shareholders even if the decision results in them losing their job. We do not, however, support excessive golden parachutes. Therefore, each proposal will be decided on a case-by- case basis.

Anti-Greenmail Proposals

We do not support greenmail. An offer extended to one shareholder should be extended to all shareholders equally across the board.

Limit Shareholders’ Rights to Call Special Meetings

We support the right of shareholders to call a special meeting.

Reviewed on a case-by-case basis.

Not For Distribution

Consideration of Nonfinancial Effects of a Merger

This proposal releases the directors from only looking at the financial effects of a merger and allows them the opportunity to consider the merger’s effects on employees, the community, and consumers.

As a fiduciary, we are obligated to vote in the best economic interests of our clients. In general, this proposal does not allow us to do that. Therefore, we generally cannot support this proposal.

Reviewed on a case-by-case basis.

Mergers, Buyouts, Spin-Offs, Restructurings

Each of the above is considered on a case-by-case basis. According to the Department of Labor, we are not required to vote for a proposal simply because the offering price is at a premium to the current market price. We may take into consideration the long term interests of the shareholders.

Military Issues

Shareholder proposals regarding military production must be evaluated on a purely economic set of criteria for our ERISA clients. As such, decisions will be made on a case-by-case basis.

In voting on this proposal for our non-ERISA clients, we will vote according to the client’s direction when applicable. Where no direction has been given, we will vote in the best economic interests of our clients. It is not our duty to impose our social judgment on others.

Northern Ireland

Shareholder proposals requesting the signing of the MacBride principles for the purpose of countering the discrimination of Catholics in hiring practices must be evaluated on a purely economic set of criteria for our ERISA clients. As such, decisions will be made on a case-by-case basis.

In voting on this proposal for our non-ERISA clients, we will vote according to client direction when applicable. Where no direction has been given, we will vote in the best economic interests of our clients. It is not our duty to impose our social judgment on others.

Not For Distribution

Opt Out of State Anti-Takeover Law

This shareholder proposal requests that a company opt out of the coverage of the state’s takeover statutes. Example: Delaware law requires that a buyer must acquire at least 85% of the company’s stock before the buyer can exercise control unless the board approves.

We consider this on a case-by-case basis. Our decision will be based on the following:

| ● | State of Incorporation

| ● | Management history of responsiveness to shareholders

| ● | Other mitigating factors

Poison Pill

In general, we do not endorse poison pills.

In certain cases where management has a history of being responsive to the needs of shareholders and the stock is very liquid, we will reconsider this position.

Reincorporation

Generally, we support reincorporation for well-defined business reasons. We oppose reincorporation if proposed solely for the purpose of reincorporating in a state with more stringent anti-takeover statutes that may negatively impact the value of the stock.

Stock Incentive Plans

Director and Employee Stock incentive plans are an excellent way to attract, hold and motivate directors and employees. However, each incentive plan must be evaluated on its own merits, taking into consideration the following:

| ● | Dilution of voting power or earnings per share by more than 10%.

| ● | Kind of stock to be awarded, to whom, when and how much.

| ● | Method of payment.

| ● | Amount of stock already authorized but not yet issued under existing stock plans.

| ● | The successful steps taken by management to maximize shareholder value.

Not For Distribution

Supermajority Vote Requirements

Supermajority vote requirements in a company’s charter or bylaws require a level of voting approval in excess of a simple majority of the outstanding shares. In general, we oppose supermajority-voting requirements. Supermajority requirements often exceed the average level of shareholder participation. We support proposals’ approvals by a simple majority of the shares voting.

Reviewed on a case-by-case basis.

Limit Shareholders Right to Act by Written Consent

Written consent allows shareholders to initiate and carry on a shareholder action without having to wait until the next annual meeting or to call a special meeting. It permits action to be taken by the written consent of the same percentage of the shares that would be required to effect proposed action at a shareholder meeting.

Reviewed on a case-by-case basis.

“Say-on-Pay” / “Say-When-on-Pay” / “Say-on-Golden-Parachutes”

Required under the Dodd-Frank Act; these proposals are non-binding advisory votes on executive compensation. We will generally vote with the Board of Directors’ recommendation(s) on advisory votes on executive compensation (“Say-on-Pay”), advisory votes on the frequency of voting on executive compensation (“Say-When-on-Pay”) and advisory votes relating to extraordinary transaction executive compensation (“Say-on-Golden-Parachutes”). In those instances when we believe that it is in our clients’ best interest, we may abstain or vote against executive compensation and/or the frequency of votes on executive compensation and/or extraordinary transaction executive compensation advisory votes.

Proxy Access

Proxy access is a tool used to attempt to promote board accountability by requiring that a company’s proxy materials contain not only the names of management nominees, but also any candidates nominated by long-term shareholders holding at least a certain stake in the company. We will review proposals regarding proxy access on a case-by-case basis taking into account the provisions of the proposal, the company’s current governance structure, the successful steps taken by management to maximize shareholder value, as well as other applicable factors.

| Item 13. | Portfolio Managers of Closed-End Management Investment Companies.

PORTFOLIO MANAGERS

Mario J. Gabelli, CFA, is Chairman, Chief Executive Officer, and Chief Investment Officer – Value Portfolios of GAMCO Investors, Inc. that he founded in 1977, and Chief Investment Officer – Value Portfolios of Gabelli Funds, LLC and GAMCO Asset Management Inc. He is also Executive Chairman of the Board of Directors of Associated Capital Group, Inc. Mr. Gabelli is a summa cum laude graduate of Fordham University and holds an MBA degree from Columbia Business School, and Honorary Doctorates from Fordham University and Roger Williams University.

James Dinsmore, CFA, joined Gabelli Funds LLC in 2015. He currently serves as portfolio manager of Gabelli Funds, LLC and manages several funds within the Gabelli/GAMCO Funds Complex. Mr. Dinsmore received a BA in Economics from Cornell University and an MBA from Rutgers University.

MANAGEMENT OF OTHER ACCOUNTS

The table below shows the number of other accounts managed by portfolio managers the total assets in each of the following categories: registered investment companies, other paid investment vehicles and other accounts as of September 30, 2025. For each category, the table also shows the number of accounts and the total assets in the accounts with respect to which the advisory fee is based on account performance.

Name of Portfolio Manager | Type of Accounts | Total No. of Accounts Managed | Total Assets | No. of Accounts where Advisory Fee is Based on Performance | Total Assets in Accounts where Advisory Fee is Based on Performance
Mario J. Gabelli, CFA | Registered Investment Companies: | 21 | $17.1 billion | 1 | $133.0 million
| Other Pooled Investment Vehicles: | 10 | $939.0 million | 8 | $917.4 million
| Other Accounts: | 792 | $7.4 billion | 0 | $0
James A. Dinsmore, CFA | Registered Investment Companies: | 3 | $395.6 million | 0 | $0
| Other Pooled Investment Vehicles: | 1 | $5.5 million | 0 | $0
| Other Accounts: | 9 | $11.8 million | 0 | $0

POTENTIAL CONFLICTS OF INTEREST

As reflected above, Messrs. Gabelli and Dinsmore manage accounts in addition to the Fund. Actual or apparent conflicts of interest may arise when a Portfolio Manager also has day-to-day management responsibilities with respect to one or more other accounts. These potential conflicts include:

ALLOCATION OF LIMITED TIME AND ATTENTION. As indicated above, Mr. Gabelli manages multiple accounts. As a result, he will not be able to devote all of his time to management of the Fund. Mr. Gabelli, therefore, may not be able to formulate as complete a strategy or identify equally attractive investment opportunities for each of those accounts as might be the case if he were to devote all of his attention to the management of only the Fund.

ALLOCATION OF LIMITED INVESTMENT OPPORTUNITIES. As indicated above, Mr. Gabelli manages managed accounts with investment strategies and/or policies that are similar to the Fund. In these cases, if the he identifies an investment opportunity that may be suitable for multiple accounts, a Fund may not be able to take full advantage of that opportunity because the opportunity may be allocated among all or many of these accounts or other accounts managed primarily by other Portfolio Managers of the Adviser, and their affiliates. In addition, in the event Mr. Gabelli determines to purchase a security for more than one account in an aggregate amount that may influence the market price of the security, accounts that purchased or sold the security first may receive a more favorable price than accounts that made subsequent transactions.

SELECTION OF BROKER/DEALERS. Because of Mr. Gabelli’s indirect ownership interest in G.research, LLC, he may have an incentive to use G.research to execute portfolio transactions for a Fund.

PURSUIT OF DIFFERING STRATEGIES. At times, Mr. Gabelli may determine that an investment opportunity may be appropriate for only some of the accounts for which he exercises investment responsibility, or may decide that certain of the funds or accounts should take differing positions with respect to a particular security. In these cases, he may execute differing or opposite transactions for one or more accounts which may affect the market price of the security or the execution of the transaction, or both, to the detriment of one or more other accounts.

VARIATION IN COMPENSATION. A conflict of interest may arise where the financial or other benefits available to Mr. Gabelli differ among the accounts that he manages. If the structure of the Adviser’s management fee or the Portfolio Manager’s compensation differs among accounts (such as where certain accounts pay higher management fees or performance-based management fees), the Portfolio Manager may be motivated to favor certain accounts over others. The Portfolio Manager also may be motivated to favor accounts in which he has an investment interest, or in which the Adviser, or their affiliates have investment interests. Similarly, the desire to maintain assets under management or to enhance a Portfolio Manager’s performance record or to derive other rewards, financial or otherwise, could influence the Portfolio Manager in affording preferential treatment to those accounts that could most significantly benefit the Portfolio Manager. For example, as reflected above, if Mr. Gabelli manages accounts which have performance fee arrangements, certain portions of his compensation will depend on the achievement of performance milestones on those accounts. Mr. Gabelli could be incented to afford preferential treatment to those accounts and thereby be subject to a potential conflict of interest.

The Adviser, and the Funds have adopted compliance policies and procedures that are designed to address the various conflicts of interest that may arise for the Adviser and their staff members. However, there is no guarantee that such policies and procedures will be able to detect and prevent every situation in which an actual or potential conflict may arise.

COMPENSATION STRUCTURE FOR MARIO J. GABELLI

Mr. Gabelli receives incentive-based variable compensation based on a percentage of net revenues received by the Adviser for managing the Fund. Net revenues are determined by deducting from gross investment management fees the firm’s expenses (other than Mr. Gabelli’s compensation) allocable to this Fund. One of the other closed-end registered investment companies managed by Mr. Gabelli has a performance (fulcrum) fee arrangement for which the Adviser’s (and Mr. Gabelli’s) compensation is adjusted up or down based on the performance of the investment company relative to an index. Additionally, he receives similar incentive based variable compensation for managing other accounts within the firm and its affiliates. This method of compensation is based on the premise that superior long-term performance in managing a portfolio should be rewarded with higher compensation as a result of growth of assets through appreciation and net investment activity. The level of compensation is not determined with specific reference to the performance of any account against any specific benchmark. Compensation for managing these accounts has two components. One component is based on a percentage of net revenues to the investment adviser for managing the account. The second component is based on absolute performance of the account, with respect to which a percentage of such performance fee is paid to Mr. Gabelli. As an executive officer of the Adviser’s parent company, GAMI, Mr. Gabelli also receives ten percent of the net operating profits of the parent company. He receives no base salary, no annual bonus, and no stock options.

COMPENSATION STRUCTURE FOR PORTFOLIO MANAGERS OF THE ADVISER OTHER THAN MARIO GABELLI

The compensation of the Portfolio Managers for the Fund is structure to enable the Adviser to attract and retain highly qualified professionals in a competitive environment. The Portfolio Managers receive a compensation package that includes a minimum draw or base salary, equity-based incentive compensation via awards of restricted stock, and incentive-based variable compensation based on a percentage of net revenue received by the Adviser for managing a Fund to the extent that the amount exceeds a minimum level of compensation. Net revenues are determined by deducting from gross investment management fees certain of the firm’s expenses (other than the respective Portfolio Manager’s compensation) allocable to the respective Fund (the incentive-based variable compensation for managing other accounts is also based on a percentage of net revenues to the investment adviser for managing the account). This method of compensation is based on the premise that superior long-term performance in managing a portfolio should be rewarded with higher compensation as a result of growth of assets through appreciation and net investment activity. The level of equity-based incentive and incentive-based variable compensation is based on an evaluation by the Adviser’s parent, GAMI, of quantitative and qualitative performance evaluation criteria. This evaluation takes into account, in a broad sense, the performance of the accounts managed by the Portfolio Manager, but the level of compensation is not determined with specific reference to the performance of any account against any specific benchmark. Generally, greater consideration is given to the performance of larger accounts and to longer term performance over smaller accounts and short-term performance.

OWNERSHIP OF SHARES IN THE FUND

Mario J. Gabelli and James A. Dinsmore each owned over $1 million and $10,001- $50,000, respectively, of shares of the Fund as of September 30, 2025.
