NOTES TO FINANCIAL STATEMENTS (UNAUDITED) 1. ORGANIZATION. The Gabelli Convertible and Income Securities Fund Inc. (the "Fund") 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. The Board of Directors (the "Board"), upon approval at a special meeting of shareholders held on February 17, 1995, voted to approve the conversion of the Fund to closed-end status, effective March 31, 1995. Effective August 1, 2002, the Fund changed its name to The Gabelli Convertible and Income Securities Fund Inc. Consistent with its new name, under normal market conditions, the Fund will invest at least 80% of its net assets 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 shareholder approval. However, the Fund has adopted a policy to provide shareholders with notice at least 60 days prior to the implementation of any change in the 80% Policy. 2. SIGNIFICANT ACCOUNTING POLICIES. The preparation of financial statements in accordance with United States ("U.S.") generally accepted accounting principles requires management to make estimates and assumptions that affect the reported amounts and disclosures in the 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. 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 instruments with remaining maturities of 60 days or less that are not credit impaired are valued at amortized cost, 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. 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. 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 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. 10 THE GABELLI CONVERTIBLE AND INCOME SECURITIES FUND INC. NOTES TO FINANCIAL STATEMENTS (CONTINUED) (UNAUDITED) In September 2006, the Financial Accounting Standards Board (the "FASB") issued Statement of Financial Accounting Standards ("SFAS") 157, Fair Value Measurements, which clarifies the definition of fair value and requires companies to expand their disclosure about the use of fair value to measure assets and liabilities in interim and annual periods subsequent to initial recognition. Adoption of SFAS 157 requires the use of the price that would be received to sell an asset or paid to transfer a liability in an orderly transaction between market participants at the measurement date. SFAS 157 is effective for financial statements issued for fiscal years beginning after November 15, 2007, and interim periods within those fiscal years. At this time, management is in the process of reviewing the requirements of SFAS 157 against its current valuation policies to determine future applicability. REPURCHASE AGREEMENTS. The Fund may enter into repurchase agreements with primary government securities dealers recognized by the Federal Reserve Board, with member banks of the Federal Reserve System, or with other brokers or dealers that meet credit guidelines established by the Adviser and reviewed by the Board. Under the terms of a typical repurchase agreement, the Fund takes possession of an underlying debt obligation subject to an obligation of the seller to repurchase, and the Fund to resell, the obligation at an agreed-upon price and time, thereby determining the yield during the Fund's holding period. The Fund will always receive and maintain securities as collateral whose market value, including accrued interest, will be at least equal to 102% of the dollar amount invested by the Fund in each agreement. The Fund will make payment for such securities only upon physical delivery or upon evidence of book entry transfer of the collateral to the account of the custodian. To the extent that any repurchase transaction exceeds one business day, the value of the collateral is marked-to-market on a daily basis to maintain the adequacy of the collateral. If the seller defaults and the value of the collateral declines or if bankruptcy proceedings are commenced with respect to the seller of the security, realization of the collateral by the Fund may be delayed or limited. At June 30, 2007, there were no open repurchase agreements. SWAP AGREEMENTS. The Fund may enter into interest rate swap or cap transactions. The use of swaps and caps is a highly specialized activity that involves investment techniques and risks different from those associated with ordinary portfolio transactions. Swap agreements may involve, to varying degrees, elements of market and counterparty risk, and exposure to loss in excess of the related amounts reflected in the Statement of Assets and Liabilities. In an interest rate swap, the Fund would agree to pay to the other party to the interest rate swap (which is known as the "counterparty") periodically a fixed rate payment in exchange for the counterparty agreeing to pay to the Fund periodically a variable rate payment that is intended to approximate the Fund's variable rate payment obligation on Series C Preferred Stock. In an interest rate cap, the Fund would pay a premium to the counterparty and, to the extent that a specified variable rate index exceeds a predetermined fixed rate, would receive from that counterparty payments of the difference based on the notional amount of such cap. Interest rate swap and cap transactions introduce additional risk because the Fund would remain obligated to pay preferred stock dividends when due in accordance with the Articles Supplementary even if the counterparty defaulted. If there is a default by the counterparty to a swap contract, the Fund will be limited to contractual remedies pursuant to the agreements related to the transaction. There is no assurance that the swap contract counterparties will be able to meet their obligations pursuant to a swap contract or that, in the event of default, the Fund will succeed in pursuing contractual remedies. The Fund thus assumes the risk that it may be delayed in or prevented from obtaining payments owed to it pursuant to a swap contract. The creditworthiness of the swap contract counterparties is closely monitored in order to minimize this risk. Depending on the general state of short-term interest rates and the returns on the Fund's portfolio securities at that point in time, such a default could negatively affect the Fund's ability to make dividend payments. In addition, at the time an interest rate swap or cap 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. If this occurs, it could have a negative impact on the Fund's ability to make dividend payments. 11 THE GABELLI CONVERTIBLE AND INCOME SECURITIES FUND INC. NOTES TO FINANCIAL STATEMENTS (CONTINUED) (UNAUDITED) 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 paid or received on swaps are reported as unrealized gains or losses in the Statement of Operations. A realized gain or loss is recorded upon payment or receipt of a periodic payment or termination of swap agreements. At June 30, 2007, there were no open swap agreements. FUTURES CONTRACTS. The Fund may engage in futures contracts for the purpose of hedging against changes in the value of its portfolio securities and in the value of securities it intends to purchase. Upon entering into a futures contract, the Fund is required to deposit with the broker an amount of cash or cash equivalents equal to a certain percentage of the contract amount. This is known as the "initial margin". Subsequent payments ("variation margin") are made or received by the Fund each day, depending on the daily fluctuations in the value of the contract, which are included in unrealized appreciation/depreciation on investments and futures contracts. The Fund recognizes a realized gain or loss when the contract is closed. There are several risks in connection with the use of futures contracts as a hedging instrument. The change in value of futures contracts primarily corresponds with the value of their underlying instruments, which may not correlate with the change in value of the hedged investments. In addition, there is the risk that the Fund may not be able to enter into a closing transaction because of an illiquid secondary market. At June 30, 2007, there were no open futures contracts. SECURITIES SOLD SHORT. The Fund may enter 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. Securities sold short at June 30, 2007 are reported in the Schedule of Investments. FORWARD FOREIGN EXCHANGE CONTRACTS. The Fund may engage in forward foreign exchange contracts for hedging a specific transaction with respect to either the currency in which the transaction is denominated or another currency as deemed appropriate by the Adviser. Forward foreign exchange contracts are valued at the forward rate and are marked-to-market daily. The change in market value is included in unrealized appreciation/depreciation on investments and foreign currency translations. When the contract is closed, the Fund records a realized gain or loss equal to the difference between the value of the contract at the time it was opened and the value at the time it was closed. The use of forward foreign exchange contracts does not eliminate fluctuations in the underlying prices of the Fund's portfolio securities, but it does establish a rate of exchange that can be achieved in the future. Although forward foreign exchange contracts limit the risk of loss due to a decline in the value of the hedged currency, they also limit any potential gain that might result should the value of the currency increase. In addition, the Fund could be exposed to risks if the counterparties to the contracts are unable to meet the terms of their contracts. At June 30, 2007, there were no open forward foreign exchange contracts. 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 the 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 12 THE GABELLI CONVERTIBLE AND INCOME SECURITIES FUND INC. NOTES TO FINANCIAL STATEMENTS (CONTINUED) (UNAUDITED) 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 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 ability 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 those of 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 AND ILLIQUID SECURITIES. The Fund may invest up to 15% of its net assets in securities for which the markets are illiquid. Illiquid securities include securities the disposition of which is subject to substantial legal or contractual restrictions. The sale of illiquid securities often requires more time and results in higher brokerage charges or dealer discounts and other selling expenses than does 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. SECURITIES TRANSACTIONS AND INVESTMENT INCOME. Securities transactions are accounted for on the trade date with realized gain or loss on investments determined by using the identified cost method. Interest income (including amortization of premium and accretion of discount) is recorded on the accrual basis. Premiums and discounts on debt securities are amortized using the effective yield to maturity method. Dividend income is recorded on the ex-dividend date except for certain dividends which are recorded as soon as the Fund is informed of the dividend. CUSTODIAN FEE CREDITS AND INTEREST EXPENSE. 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". When cash balances are overdrawn, the Fund is charged an overdraft fee of 2.00% above the Federal Funds rate on outstanding balances. This amount, if any, would be shown as "interest expense" in the Statement of Operations. DISTRIBUTIONS TO SHAREHOLDERS. Distributions to common shareholders are recorded on the ex-dividend date. Distributions to shareholders are based on income and capital gains as determined in accordance with federal income tax regulations, which may differ from income and capital gains as determined under U.S. generally accepted accounting principles. 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 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, 13 THE GABELLI CONVERTIBLE AND INCOME SECURITIES FUND INC. NOTES TO FINANCIAL STATEMENTS (CONTINUED) (UNAUDITED) 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 shareholders of the Fund's 6.00% Series B Cumulative Preferred Stock and Series C Auction Rate Cumulative Preferred Stock ("Cumulative Preferred Stock") are recorded on a daily basis and are determined as described in Note 5. The tax character of distributions paid during the year ended December 31, 2006 was as follows: COMMON PREFERRED --------- --------- DISTRIBUTIONS PAID FROM: Ordinary income (inclusive of short-term capital gains) .. $5,635,363 $1,574,483 Net long-term capital gains ................ 4,070,407 1,137,245 ---------- ---------- Total distributions paid ................... $9,705,770 $2,711,728 ========== ========== During 2006, distributions were made from current earnings and profits that were in excess of required distributions and treated as ordinary income. 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 unrealized appreciation/(depreciation) at June 30, 2007: GROSS GROSS COST/ UNREALIZED UNREALIZED NET UNREALIZED (PROCEEDS) APPRECIATION DEPRECIATION APPRECIATION ---------- ------------ ------------ -------------- Investments ..... $145,249,820 $13,332,149 $(3,954,355) $9,377,794 Short sales ..... (95,955) 2,385 -- 2,385 ----------- ----------- ---------- $13,334,534 $(3,954,355) $9,380,179 =========== =========== ========== In July 2006, the FASB issued Interpretation No. 48, "Accounting for Uncertainty in Income Taxes, an Interpretation of FASB Statement No. 109" ("the Interpretation"). The Interpretation established for all entities, including pass-through entities such as the Fund, a minimum threshold for financial statement recognition of the benefit of positions taken in filing tax returns (including whether an entity is taxable in a particular jurisdiction), and required certain expanded tax disclosures. The Interpretation was implemented by the Fund on June 29, 2007 and applied to all open tax years as of the effective date. Management has evaluated the application of the Interpretation to the Fund, and the adoption of the Interpretation had no impact on the amounts reported in the financial statements. 3. AGREEMENTS AND TRANSACTIONS WITH AFFILIATES. 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 the Fund's 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. The Adviser has agreed to reduce the management fee on the incremental assets attributable to the Cumulative Preferred Stock if the total return of the NAV of the common shares of the Fund, including distributions and advisory fee subject to reduction, does not exceed the stated dividend rate or corresponding swap rate of each particular series of the Cumulative Preferred Stock for the fiscal year. 14 THE GABELLI CONVERTIBLE AND INCOME SECURITIES FUND INC. NOTES TO FINANCIAL STATEMENTS (CONTINUED) (UNAUDITED) The Fund's total return on the NAV of the Common Shares is monitored on a monthly basis to assess whether the total return on the NAV of the Common Shares exceeds the stated dividend rate or corresponding swap rate of each particular series of Cumulative Preferred Stock for the period. For the six months ended June 30, 2007, the Fund's total return on the NAV of the Common Shares did not exceed the stated dividend rate or net swap expense of all outstanding Preferred Stock. Thus, management fees were not accrued in the amount of $246,805. During the six months ended June 30, 2007, the Fund paid brokerage commissions of $46,163 to Gabelli & Company, Inc. ("Gabelli & Company"), an affiliate of the Adviser. 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. During the six months ended June 30, 2007, the Fund paid or accrued $22,621 to the Adviser in connection with the cost of computing the Fund's NAV. The Fund is assuming its portion of the allocated cost of the Gabelli Funds' Chief Compliance Officer in the amount of $2,004 for the six months ended June 30, 2007, which is included in payroll expenses in the Statement of Operations. As per the approval of the Board, the Fund compensates an officer of the Fund that is employed by the Fund and is not employed by the Adviser (although the officer may receive incentive-based variable compensation from affiliates of the Adviser). For the six months ended June 30, 2007 the Fund paid or accrued $73,059, which is included in payroll expenses in the Statement of Operations. The Fund pays each Director that is not considered to be an affiliated person an annual retainer of $5,000 plus $750 for each Board meeting attended and they are reimbursed for any out of pocket expenses incurred in attending meetings. All Board committee members receive $500 per meeting attended. In addition, the Audit Committee Chairman receives an annual fee of $3,000 and the Nominating Committee Chairman receives an annual fee of $2,000. 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 proceeds from the sales of securities for the six months ended June 30, 2007, other than short-term securities, aggregated $67,804,777 and $39,113,566, 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, 2007, the Fund did not repurchase any shares of its common stock in the open market. Transactions in common stock were as follows: SIX MONTHS ENDED JUNE 30, 2007 YEAR ENDED (UNAUDITED) DECEMBER 31, 2006 --------------------- --------------------- SHARES AMOUNT SHARES AMOUNT -------- ----------- ----------- -------- Net increase from shares issued upon reinvestment of distributions ............... 146,786 $1,275,228 307,518 $2,593,272 The Fund's Articles of Incorporation authorize the issuance of up to 2,000,000 shares of $0.001 par value Cumulative Preferred Stock. The Cumulative 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 shareholders. Dividends 15 THE GABELLI CONVERTIBLE AND INCOME SECURITIES FUND INC. NOTES TO FINANCIAL STATEMENTS (CONTINUED) (UNAUDITED) on shares of the Cumulative Preferred Stock are cumulative. The Fund is required by the 1940 Act and by the Articles Supplementary to meet certain asset coverage tests with respect to the Cumulative 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 6.00% Series B and Series C Auction Rate Cumulative Preferred Stock at redemption prices of $25.00 and $25,000, respectively, per share plus an amount equal to the accumulated and unpaid dividends whether or not declared on such shares in order to meet these requirements. Additionally, failure to meet the foregoing asset coverage requirements could restrict the Fund's ability to pay dividends to common shareholders and could lead to sales of portfolio securities at inopportune times. The income received on the Fund's assets may vary in a manner unrelated to the fixed and variable rates, which could have either a beneficial or detrimental impact on net investment income and gains available to common shareholders. On March 18, 2003, the Fund received net proceeds of $23,994,241 after underwriting discounts of $787,500 and offering expenses of $218,259 from the public offering of 1,000,000 shares of 6.00% Series B Cumulative Preferred Stock. Commencing March 19, 2008 and thereafter, the Fund, at its option, may redeem the 6.00% Series B Cumulative Preferred Stock in whole or in part at the redemption price at any time. The Board has authorized the repurchase on the open market at prices less than the $25 liquidation value of the Cumulative Preferred Stock. During the six months ended June 30, 2007, the Fund did not repurchase any shares of 6.00% Series B Cumulative Preferred Stock. At June 30, 2007, 990,800 shares of 6.00% Series B Cumulative Preferred Stock were outstanding and accrued dividends amounted to $24,770. On March 18, 2003, the Fund received net proceeds of $24,531,741 after underwriting discounts of $250,000 and offering expenses of $218,259 from the public offering of 1,000 shares of Series C Auction Rate Cumulative Preferred Stock. The dividend rate, as set by the auction process, which is generally held every seven days, is expected to vary with short-term interest rates. The dividend rates of Series C Auction Rate Cumulative Preferred Stock ranged from 4.90% to 5.25% for the six months ended June 30, 2007. Existing shareholders may submit an order to hold, bid, or sell such shares on each auction date. Series C Auction Rate Cumulative Preferred Stock shareholders may also trade shares in the secondary market. The Fund, at its option, may redeem the Series C Auction Rate Cumulative Preferred Stock in whole or in part at the redemption price at any time. During the six months ended June 30, 2007, the Fund did not redeem any shares of Series C Auction Rate Cumulative Preferred Stock. At June 30, 2007, 1,000 shares of Series C Auction Rate Cumulative Preferred Stock were outstanding with an annualized dividend rate of 5.10% and accrued dividends amounted to $17,708. The holders of Cumulative Preferred Stock generally are entitled to one vote per share held on each matter submitted to a vote of shareholders of the Fund and will vote together with holders of common stock as a single class. The holders of Cumulative 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 of Directors. 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. 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 and expects the risk of loss to be remote. 16 THE GABELLI CONVERTIBLE AND INCOME SECURITIES FUND INC. NOTES TO FINANCIAL STATEMENTS (CONTINUED) (UNAUDITED) 7. OTHER MATTERS. The Adviser and/or affiliates received subpoenas from the Attorney General of the State of New York and the SEC requesting information on mutual fund share trading practices involving certain funds managed by the Adviser. GAMCO Investors, Inc. ("GAMCO"), the Adviser's parent company, responded to these requests for documents and testimony. In June 2006, GAMCO began discussions with the SEC regarding a possible resolution of their inquiry. In February 2007, the Adviser made an offer of settlement to the staff of the SEC for communication to the Commission for its consideration to resolve this matter. This offer of settlement is subject to agreement regarding the specific language of the SEC's administrative order and other settlement documents. On a separate matter, in September 2005, the Adviser was informed by the staff of the SEC that the staff may recommend to the Commission that an administrative remedy and a monetary penalty be sought from the Adviser in connection with the actions of two of seven closed-end funds managed by the Adviser relating to Section 19(a) and Rule 19a-1 of the 1940 Act. These provisions require registered investment companies to provide written statements to shareholders when a dividend is made from a source other than net investment income. While the two closed-end funds sent annual statements and provided other materials containing this information, the funds did not send written statements to shareholders with each distribution in 2002 and 2003. The Adviser believes that all of the funds are now in compliance. The Adviser believes that these matters would have no effect on the Fund or any material adverse effect on the Adviser or its ability to manage the Fund. 17 THE GABELLI CONVERTIBLE AND INCOME SECURITIES FUND INC.

See accompanying notes to financial statements. 19 THE GABELLI CONVERTIBLE AND INCOME SECURITIES FUND INC. BOARD CONSIDERATION AND RE-APPROVAL OF INVESTMENT ADVISORY CONTRACT (UNAUDITED) At its meeting on May 16, 2007, the Board of Directors ("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 manager, the depth of the analyst pool available to the Adviser and the portfolio manager, 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 manager. INVESTMENT PERFORMANCE. The Independent Board Members reviewed the short, medium, and longer-term performance of the Fund against a peer group of convertible securities and income/preferred stock closed-end funds. The Independent Board Members noted that the Fund's comparative performance was reasonable particularly in light of the Fund's conservative stance. PROFITABILITY. The Independent Board Members reviewed summary data regarding the profitability of the Fund to the Adviser and found the profitability to be normal. The Independent Board Members also noted that a portion of the Fund's portfolio transactions were executed by an affiliate broker and that the Adviser received a moderate amount of soft dollar benefits through the Fund's portfolio brokerage. ECONOMIES OF SCALE. The Independent Board Members discussed 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. 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. 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 to similar expense ratios of the peer group of closed-end funds 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 group. The Independent Board Members were presented with, but did not consider to be material to their decision, various information comparing the advisory fee to the fee for other types of accounts managed by the Adviser. CONCLUSIONS. The Independent Board Members concluded that the Fund enjoyed highly experienced portfolio management services, good ancillary services, and a reasonable performance record within its conservative stance. The Independent Board Members also concluded that the Fund's expense ratios were reasonable 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 investment advisory agreement to the full Board. 20 AUTOMATIC DIVIDEND REINVESTMENT AND VOLUNTARY CASH PURCHASE PLANS ENROLLMENT IN THE PLAN It is the policy of The Gabelli Convertible and Income Securities Fund Inc. (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 issue shares of common stock 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 stock 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 must submit this request in writing to: The Gabelli Convertible and Income Securities Fund Inc. c/o Computershare P.O. Box 43010 Providence, RI 02940-3010 Shareholders requesting this cash election must include the shareholder's name and address as they appear on the share certificate. Shareholders with additional questions regarding the Plan or requesting a copy of the terms of the plan may contact Computershare at (800) 336-6983. 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 dividends 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 stock 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 stock 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 stock 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 stock. 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 stock at the time of valuation exceeds the market price of the common stock, 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 common stock 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 stock exceeds the then current net asset value. 21 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. 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 pro rata share of the brokerage commissions. Brokerage charges for such purchases are expected to be less than the usual brokerage charge for such transactions. It is suggested that any voluntary cash payments be sent to Computershare, P.O. Box 43010, Providence, RI02940-3010 such that Computershare receives such payments approximately 10 days before the 1st and 15th of the month. Funds not received at least five days before the investment date shall be held for investment until the next purchase date. A payment may be withdrawn without charge if notice is received by Computershare at least 48 hours before such payment is to be invested. SHAREHOLDERS WISHING TO LIQUIDATE SHARES HELD AT COMPUTERSHARE must do so in writing or by telephone. Please submit your request to the above mentioned address or telephone number. Include in your request your name, address, and account number. The cost to liquidate shares is $2.50 per transaction as well as the brokerage commission incurred. Brokerage charges are expected to be less than the usual brokerage charge for such transactions. For more information regarding the Automatic Dividend Reinvestment Plan and Voluntary Cash Purchase Plan, brochures are 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 90 days before the record date for such dividend or distribution. The Plan also may be amended or terminated by Computershare on at least 90 days written notice to participants in the Plan. 22 DIRECTORS AND OFFICERS THE GABELLI CONVERTIBLE AND INCOME SECURITIES FUND INC.
