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. On January 1, 2008, the Fund adopted Statement of Financial Accounting Standard No. 157, "Fair Value Measurements" ("SFAS 157") that clarifies the definition of fair value for financial reporting, establishes a framework for measuring fair value, and requires additional disclosures about the use of fair value measurements. The three levels of the fair value hierarchy under SFAS 157 are described 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 Fund's determinations as to the fair value of investments). 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 inputs used to value the Fund's net assets as of September 30, 2008 is as follows: OTHER FINANCIAL INVESTMENTS IN INSTRUMENTS SECURITIES (UNREALIZED VALUATION INPUTS (MARKET VALUE) DEPRECIATION)* ---------------- -------------- --------------- Level 1 - Quoted Prices $ 51,685,189 -- Level 2 - Other Significant Observable Inputs 54,168,119 $(42,106) Level 3 - Significant Unobservable Inputs 94,883 -- ------------ -------- Total $105,948,191 $(42,106) ============ ======== ---------- * Other financial instruments are derivative instruments not reflected in the Schedule of Investments, such as futures, forwards, and swaps, which are valued at the unrealized appreciation/depreciation on the investment. 6 THE GABELLI CONVERTIBLE AND INCOME SECURITIES FUND INC. NOTES TO SCHEDULE OF INVESTMENTS (CONTINUED) (UNAUDITED) The following is a reconciliation of Level 3 investments for which significant unobservable inputs were used to determine fair value: INVESTMENTS IN SECURITIES (MARKET VALUE) -------------- BALANCE AS OF 12/31/07 $ 437,162 Accrued discounts/(premiums) 16,987 Realized gain/(loss) -- Change in unrealized appreciation/(depreciation) 127,034 Net purchases/(sales) (486,300) Transfers in and/or out of Level 3 -- --------- BALANCE AS OF 09/30/08 $ 94,883 ========= In March 2008, the Financial Accounting Standards Board (the "FASB") issued Statement of Financial Accounting Standard No. 161, "Disclosures about Derivative Instruments and Hedging Activities" ("SFAS 161") that is effective for fiscal years beginning after November 15, 2008. SFAS 161 is intended to improve financial reporting for derivative instruments by requiring enhanced disclosure that enables investors to understand how and why an entity uses derivatives, how derivatives are accounted for, and how derivative instruments affect an entity's results of operations and financial position. Management is currently evaluating the implications of SFAS 161 on the Fund's financial statement disclosures. 2. SWAP AGREEMENTS. The Fund may enter into equity and contract for difference swap 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. In a swap, a set of future cash flows are 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. 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 the a 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. If this occurs, it could have a negative impact on the Fund's ability to make dividend payments. The use of derivative instruments involves, to varying degrees, elements of market and counterparty risk in excess of the amount recognized below. The Fund has entered into a contract for difference swap agreement with Bear, Stearns International Limited. Details of the swap at September 30, 2008 are as follows: NOTIONAL EQUITY SECURITY INTEREST RATE/ TERMINATION NET UNREALIZED AMOUNT RECEIVED EQUITY SECURITY PAID DATE DEPRECIATION ------------------------ --------------------- ------------------------ ----------- -------------- Overnight LIBOR plus Market Value 40 bps plus Market Value Appreciation on: Depreciation on: $325,707 (47,500 Shares) Rolls-Royce Group plc Rolls-Royce Group plc 12/15/08 $(42,106) 7 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 credit 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. 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. 8 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, RI 02940-3010 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. 9 THE GABELLI CONVERTIBLE AND INCOME SECURITIES FUND INC.
