	(a)	Performance returns for periods of less than one year are not annualized. The Bloomberg Barclays Government/Credit Bond Index is a market value weighted index that tracks the performance of fixed rate, publicly placed, dollar denominated obligations. The Lipper Convertible Securities Fund Average reflects the average performance of open-end funds classified in this particular category. Dividends and interest income are considered reinvested. You cannot invest directly in an index.
	(b)	Total returns and average annual returns reflect changes in the NAV per share, reinvestment of distributions at NAV on the ex-dividend date, and adjustments for rights offerings and are net of expenses. Since inception return is based on an initial NAV of $10.00.
	(c)	Total returns and average annual returns reflect changes in closing market values on the NYSE, reinvestment of distributions, and adjustments for rights offerings. Since inception return is based on an initial offering price of $11.25 on March 31, 1995.
	(d)	Since inception return is from March 31, 1995 when the Fund converted to closed-end status; before this date, the Fund had no operating history on the NYSE.
	(e)	The Bloomberg Barclays Government/Credit Bond Index inception date is January 29, 1999.
	(f)	From June 30, 1989, the date closest to the Fund’s inception for which data is available.

	Investors should carefully consider the investment objectives, risks, charges, and expenses of the Fund before investing. Returns represent past performance and do not guarantee future results. Investment returns and the principal value of an investment will fluctuate. The Fund’s use of leverage may magnify the volatility of net asset value changes versus funds that do not employ leverage. When shares are sold, they may be worth more or less than their original cost. Current performance may be lower or higher than the performance data presented. Visit www.gabelli.com for performance information as of the most recent month end.

The Gabelli Convertible and Income Securities Fund Inc.

Notes to Financial Statements (Unaudited)

1. Organization. The Gabelli Convertible and Income Securities Fund Inc. is a diversified closed-end management investment company registered under the Investment Company Act of 1940, as amended (the 1940 Act), whose 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 was incorporated in Maryland on December 19, 1988 as a diversified open-end management investment company and commenced investment operations on July 3, 1989 as The Gabelli Convertible Securities Fund, Inc. 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.

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.

The global outbreak of the novel coronavirus disease, known as COVID-19, has caused adverse effects on many companies, sectors, nations, regions and the markets in general, and may continue for an unpredictable duration. The effects of this pandemic may materially impact the value and performance of the Fund, its ability to buy and sell fund investments at appropriate valuations, and its ability to achieve its investment objectives.

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

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

The Gabelli Convertible and Income Securities Fund Inc.

Notes to Financial Statements (Unaudited) (Continued)

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

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

●	Level 1 — 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 June 30, 2021 is as follows:

Additional Information to Evaluate Qualitative Information.

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

The Gabelli Convertible and Income Securities Fund Inc.

Notes to Financial Statements (Unaudited) (Continued)

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.

Derivative Financial Instruments. The Fund may engage in various portfolio investment strategies by investing in derivative financial instruments for the purposes of increasing the income of the Fund, hedging against changes in the value of its portfolio securities and in the value of securities it intends to purchase, or hedging against a specific transaction with respect to either the currency in which the transaction is denominated or another currency. Investing in certain derivative financial instruments, including participation in the options, futures, or swap markets, entails certain execution, liquidity, hedging, tax, and securities, interest, credit, or currency market risks. Losses may arise if the Adviser’s prediction of movements in the direction of the securities, foreign currency, and interest rate markets is inaccurate. Losses may also arise if the counterparty does not perform its duties under a contract, or, in the event of default, the Fund may be delayed in or prevented from obtaining payments or other contractual remedies owed to it under derivative contracts. The creditworthiness of the counterparties is closely monitored in order to minimize these risks. Participation in derivative transactions involves investment risks, transaction costs, and potential losses to which the Fund would not be subject absent the use of these strategies. The consequences of these risks, transaction costs, and losses may have a negative impact on the Fund’s ability to pay distributions.

Collateral requirements differ by type of derivative. Collateral requirements are set by the broker or exchange clearing house for exchange traded derivatives, while collateral terms are contract specific for derivatives traded over-the-counter. Securities pledged to cover obligations of the Fund under derivative contracts are noted in the Schedule of Investments. Cash collateral, if any, pledged for the same purpose will be reported separately in the Statement of Assets and Liabilities.

The Fund’s policy with respect to offsetting is that, absent an event of default by the counterparty or a termination of the agreement, the master agreement does not result in an offset of reported amounts of financial assets and financial liabilities in the Statement of Assets and Liabilities across transactions between the Fund and the applicable counterparty. The enforceability of the right to offset may vary by jurisdiction.

The Gabelli Convertible and Income Securities Fund Inc.

Notes to Financial Statements (Unaudited) (Continued)

The Fund’s derivative contracts held at June 30, 2021, if any, are not accounted for as hedging instruments under GAAP and are disclosed in the Schedule of Investments together with the related counterparty.

Swap Agreements. The Fund may enter into equity contract for difference swap transactions for the purpose of increasing the income of the Fund. The use of swaps is a highly specialized activity that involves investment techniques and risks different from those associated with ordinary portfolio security 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 able to obtain a replacement transaction or that the terms of the replacement will not be as favorable as on the expiring transaction.

Unrealized gains related to swaps are reported as an asset and unrealized losses are reported as a liability in the Statement of Assets and Liabilities. The change in value of swaps, including the accrual of periodic amounts of interest to be received or paid on swaps, is reported as unrealized gain or loss in the Statement of Operations. A realized gain or loss is recorded upon receipt or payment of a periodic payment or termination of swap agreements. During the six months ended June 30, 2021, the Fund held no investments in equity contract for difference swap agreements.

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 Commission (CFTC). Pursuant to amendments by the CFTC to Rule 4.5 under the Commodity Exchange Act (CEA), the Adviser has filed a notice of exemption from registration as a “commodity pool operator” with respect to the Fund. The Fund and the Adviser are therefore not subject to registration or regulation as a commodity pool operator under the CEA. In addition, certain trading restrictions are now applicable to the Fund which 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. 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, in the future the Fund will be 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 Adviser to manage the Fund, and on the Fund’s performance.

The Gabelli Convertible and Income Securities Fund Inc.

Notes to Financial Statements (Unaudited) (Continued)

Securities Sold Short. The Fund enters into short sale transactions. Short selling involves selling securities that may or may not be owned and, at times, borrowing the same securities for delivery to the purchaser, with an obligation to replace such borrowed securities at a later date. The proceeds received from short sales are recorded as liabilities and the Fund records an unrealized gain or loss to the extent of the difference between the proceeds received and the value of an open short position on the day of determination. The Fund records a realized gain or loss when the short position is closed out. By entering into a short sale, the Fund bears the market risk of an unfavorable change in the price of the security sold short. Dividends on short sales are recorded as an expense by the Fund on the ex-dividend date and interest expense is recorded on the accrual basis. The broker retains collateral for the value of the open positions, which is adjusted periodically as the value of the position fluctuates. At June 30, 2021, there were no short sales outstanding.

Series E 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

The Gabelli Convertible and Income Securities Fund Inc.

Notes to Financial Statements (Unaudited) (Continued)

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. For the restricted security held at June 30, 2021, refer to the Schedule of Investments.

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. These reclassifications have no impact on the NAV of the Fund.

Distributions to stockholders of the Fund’s 4.000% Series E Cumulative Preferred Stock (Series E Preferred) are recorded on a daily basis and are determined as described in Note 5.

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.

The Gabelli Convertible and Income Securities Fund Inc.

Notes to Financial Statements (Unaudited) (Continued)

The tax character of distributions paid during the year ended December 31, 2020 was as follows:

	Common
Distributions paid from:
Ordinary income (inclusive of short term capital gains)	$	2,490,977
Net long term capital gains		6,543,288
Total distributions paid	$	9,034,265

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

The following summarizes the tax cost of investments and the related net unrealized appreciation at June 30, 2021:

		Cost		Gross Unrealized Appreciation		Gross Unrealized Depreciation		Net Unrealized Appreciation
Investments		$123,725,239		$40,234,864		$(805,295)		$39,429,569

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. For the six months ended June 30, 2021, the Fund did not incur any income tax, interest, or penalties. As of June 30, 2021, the Adviser has reviewed all open tax years and concluded that there was no impact to the Fund’s net assets or results of operations. The Fund’s federal and state tax returns for the prior three fiscal years remain open, subject to examination. On an ongoing basis, the Adviser will monitor the Fund’s tax positions to determine if adjustments to this conclusion are necessary.

3. Investment Advisory Agreement and Other Transactions. The Fund has entered into an investment advisory agreement (the Advisory Agreement) with the Adviser which provides that the Fund will pay the Adviser a fee, computed 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.

During the six months ended June 30, 2021, the Fund paid $360 in brokerage commissions on security trades to G.research, LLC, an affiliate of the Adviser.

During the six months ended June 30, 2021, 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 $1,119.

The Gabelli Convertible and Income Securities Fund Inc.

Notes to Financial Statements (Unaudited) (Continued)

The cost of calculating the Fund’s NAV per share is a Fund expense pursuant to the Advisory Agreement between the Fund and the Adviser. Under the sub-administration agreement with Bank of New York Mellon, the fees paid include the cost of calculating the Fund’s NAV. The Fund reimburses the Adviser for this service. During the six months ended June 30, 2021, the Fund accrued $22,500 in accounting fees in the Statement of Operations.

As per the approval of the Board, the Fund compensates officers of the Fund, who are employed by the Fund and are not employed by the Adviser (although the officers may receive incentive based variable compensation from affiliates of the Adviser). During the six months ended June 30, 2021, the Fund accrued $38,933 in payroll expenses in the Statement of Operations.

The Fund pays retainer and per meeting fees to Directors not affiliated with the Adviser, plus specified amounts to the Lead Director and Audit Committee Chairman. Directors are also reimbursed for out of pocket expenses incurred in attending meetings. Directors who are directors or employees of the Adviser or an affiliated company receive no compensation or expense reimbursement from the Fund.

4. Portfolio Securities. Purchases and sales of securities during the six months ended June 30, 2021, other than short term securities and U.S. Government obligations, aggregated $31,631,992 and $35,959,455, respectively. Purchases and sales of U.S. Government Obligations for the six months ended June 30, 2021, aggregated $25,084,379 and $25,851,249, respectively.

5. 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 common shares on the open market when the shares are trading at a discount of 10% or more (or such other percentage as the Board may determine from time to time) from the NAV of the shares. During the six months ended June 30, 2021 and the year ended December 31, 2020, the Fund did not repurchase any shares of its common stock in the open market.

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 E Preferred at a redemption price of $100 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 October 16, 2019, the Fund issued 350,000 shares of Series E Preferred 4.00% Cumulative Preferred Stock, receiving $34,876,680 after the deduction of offering expenses of $123,320. The Series E has a liquidation value of $100 per share and an annual dividend rate of 4.00%. The Series E Preferred is subject to mandatory

redemption by the Fund on October 16, 2023. At June 30, 2021, 337,600 shares of Series E Preferred were outstanding and accrued dividends amounted to $18,756.

From April 16, 2020 to October 15, 2020 (the First Put Period), the Fund would accept for redemption, in aggregate, up to 10% of the outstanding Series E Preferred. From October 16, 2020 to October 15, 2021 (the Second Put Period), the Fund will accept for redemption, in aggregate, up to 20% of the outstanding Series E Preferred, with the number of outstanding Series E Preferred determined as of October 16, 2020. A Series E Preferred stockholder may, after notice to the Fund 30 days prior to the respective put period, submit one redemption request for part or all of such holdings in each put period, subject to the respective foregoing percentage limitations. The Fund will redeem such Shares at the liquidation preference plus any accumulated and unpaid dividends. If the capacity limitations for the First Put Period or the Second Put Period are exceeded, the Fund will redeem the Series E Preferred on a pro rata basis. During the period from October 16, 2021 to October 15, 2022 (the Third Put Period), a Series E Preferred stockholder may, with notice 45 days prior to the Fund, submit part or all of such Shares without limitation for redemption at the liquidation preference plus any accumulated and unpaid dividends.

On October 16, 2023, the Fund will redeem any Series E Preferred not previously liquidated at the liquidation preference plus any accumulated and unpaid dividends.

On May 17, 2020, 12,400 shares of the Series E were put back to the Fund at their liquidation preference of $100 per share plus accrued and unpaid dividends.

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 Preferred Stock 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.

6. 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 60 days prior to the implementation of any change in the 80% Policy.

7. 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.

Board Consideration and Re-Approval of Investment Advisory Agreement (Unaudited)

At its meeting on May 12, 2021, the Board of the Fund approved the continuation of the investment advisory contract with the Adviser for the Fund on the basis of the recommendation by the directors who are not “interested persons” of the Fund (the Independent Board Members). The following paragraphs summarize the material information and factors considered by the Independent Board Members as well as their conclusions relative to such factors.

Nature, Extent, and Quality of Services. The Independent Board Members considered information regarding the portfolio managers, the depth of the analyst pool available to the Adviser and the portfolio managers, the scope of supervisory, administrative, shareholder, and other services supervised or provided by the Adviser and the absence of significant service problems reported to the Board. The Independent Board Members noted the experience, length of service, and reputation of the portfolio managers.

Investment Performance. The Independent Board Members reviewed the performance of the Fund for the one, three, five, and ten year periods ended March 31, 2021 against a peer group of convertible and total return income oriented funds selected by the Adviser (the Adviser Peer Group) and against a peer group consisting of funds in the Fund’s Lipper category (the Lipper Peer Group). The Independent Board Members noted that the Fund’s performance was in the third quartile for the one year period and in the second quartile for the three year, five year, and ten year periods for the Adviser Peer Group, and in the second quartile for the one and ten year periods and in the first quartile in the three and five year periods for the Lipper Peer Group.

Profitability. The Independent Board Members reviewed summary data regarding the profitability of the Fund to the Adviser both with an administrative overhead charge and without such charge. The Board also reviewed materials showing that a portion was executed by the Adviser’s affiliated broker, resulting in incremental profits to the broker.

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

Sharing of Economies of Scale. The Independent Board Members noted that the investment advisory fee schedule for the Fund does not take into account any potential economies of scale that may develop.

Service and Cost Comparisons. The Independent Board Members compared the expense ratios of the investment advisory fee, other expenses, and total expenses of the Fund with similar expense ratios of the Adviser Peer Group and the Lipper Peer Group and noted that the advisory fee includes substantially all administrative services of the Fund as well as investment advisory services of the Adviser. The Independent Board Members noted that the Fund’s expense ratios were above average and the Fund’s size was below average within the applicable peer groups. The Independent Board Members noted that the management fee reflected by Lipper is the aggregate fee paid by a fund (including fees attributable to both common and preferred shares) as a percentage of the assets attributable to common shares, which may result in the calculation of a higher management fee percentage than the stated contractual fee for any funds employing leverage. The Independent Board Members were presented with information comparing the advisory fee to the fee for other types of accounts managed by the Adviser.

Board Consideration and Re-Approval of Investment Advisory Agreement (Unaudited) (Continued)

Conclusions. The Independent Board Members concluded that the Fund enjoyed highly experienced portfolio management services, good ancillary services and an acceptable performance record within its relatively conservative stance. The Independent Board Members also concluded that the Fund’s expense ratios were acceptable in light of the Fund’s size, and that, in part due to the Fund’s structure as a closed-end fund, economies of scale were not a significant factor in their thinking. The Independent Board Members did not view the potential profitability of ancillary services as material to their decision. On the basis of the foregoing and without assigning particular weight to any single conclusion, the Independent Board Members determined to recommend continuation of the Advisory Agreement to the full Board.

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