THE GABELLI ABC FUND ANNUAL REPORT DECEMBER 31, 2005 TO OUR SHAREHOLDERS, The Sarbanes-Oxley Act requires a Fund's principal executive and financial officers to certify the entire contents of the semi-annual and annual shareholder reports in a filing with the Securities and Exchange Commission on Form N-CSR. This certification would cover the portfolio manager's commentary and subjective opinions if they are attached to or a part of the financial statements. Many of these comments and opinions would be difficult or impossible to certify. Because we do not want our portfolio managers to eliminate their opinions and/or restrict their commentary to historical facts, we have separated their commentary from the financial statements and investment portfolio and have sent it to you separately. Both the commentary and the financial statements, including the schedule of investments, will be available on our website at www.gabelli.com/funds. Enclosed are the audited financial statements and the investment portfolio as of December 31, 2005 with a description of factors that affected the performance during the past year. PERFORMANCE DISCUSSION The Gabelli ABC Fund gained 1.38% during the fourth quarter and 4.98% for full year 2005. We note that 2005 was the 12th consecutive calendar year during which the Fund had positive performance. Merger and acquisition (M&A) activity in the U.S. exceeded $1.1 trillion during 2005, a 33% increase from 2004's announced total of $849 billion. Announced worldwide M&A volume was over $2.7 trillion, making 2005 the third best year ever for M&A and the best year since 2000. The premium buyers were willing to pay for acquisitions hit a record low of 20 percent compared to the peak of 29 percent reached in 2000. During the year, the U.S. accounted for approximately 40% of global transactions. Private equity acquisitions of U.S. companies rose to record level in 2005. Sectors that led in M&A activity in the U.S. in the past twelve months were Energy and Power, Financials, and Media and Entertainment. The three largest deals of the year in which the Fund participated were: PROCTER & GAMBLE (PG - $57.88 - NYSE) $57 billion acquisition of Gillette. BANK OF AMERICA (BAC - $46.15 - NYSE) announcement on June 30th to acquire MBNA Corp for $35.8 billion. GAS NATURAL SDG, S.A. (GAS.MC - [EURO] 23.66 - MADRID STOCK EXCHANGE) of Spain announced on September 5th that it intends to acquire 100% of Endesa S.A. for approximately $51.4 billion. The Fund invests in "event" driven situations such as announced mergers, acquisitions, and reorganizations. When a company agrees to be acquired by another company, its stock price often quickly rises to just below the stated acquisition price. If the Adviser, through extensive research, determines that the acquisition is likely to be consummated on schedule at the stated acquisition price, then the Fund may purchase the selling company's securities, offering the Fund the possibility of generous returns relative to cash equivalents with a limited risk of capital. Among the deals that the Fund participated in during the year were Alamosa Holdings Inc., Anteon International Corp., Chiron Corp., Dofasco Inc., Georgia-Pacific, Guidant Corp., La Quinta Corp., Endesa SA, Reebok International Ltd., E-Loan Inc., Imagistics International Inc., PalmSource Inc., Vicuron Pharmaceuticals Inc., Ameritrade Holding Corp., Kaman Corp., Cuno Inc., Overnite Corp., Retek Inc., Accredo Health Inc., United Defense Industries Inc., and Insurance Auto Auctions. Some of the best performers in 2005 from the long-term holdings in the ABC Fund include Kaman Corp. +55.7%, Argonaut Group Inc. +55.09%, Mirant Corp. +48.1%, Gold Fields Ltd. +41.3%, Revlon Inc. +34.8%, and Gold Banc Corp. Inc. +24.6%. Positions that the Fund had at the beginning of 2005 that hurt performance during the year were Dana Corp. -58.6%, Packaging Dynamics Corp. - -22.2%, Las Vegas Sands Corp. -17.8%, Grupo Continental SA -17.5%, Monolithic System Technology Inc. -11.7%, Provide Commerce Inc. -10.9%, and Guidant Corp. - -10.2. The Fund's cash and cash equivalents at the end of 2005 was slightly over 18% or approximately 46 percentage points less than the level at the end of 2004. Higher short-term interest rates from our short-term U.S.Treasury Bill investments during the year also bolstered our return. Sincerely yours, /s/ Bruce N. Alpert Bruce N.

All mutual funds have operating expenses. As a shareholder of a fund, you incur ongoing costs, which include costs for portfolio management, administrative services, and shareholder reports (like this one), among others. Operating expenses, which are deducted from a fund's gross income, directly reduce the investment return of a fund. When a fund's expenses are expressed as a percentage of its average net assets, this figure is known as the expense ratio. The following examples are intended to help you understand the ongoing costs (in dollars) of investing in your Fund and to compare these costs with those of other mutual funds. The examples are based on an investment of $1,000 made at the beginning of the period shown and held for the entire period. The Expense Table below illustrates your Fund's costs in two ways: ACTUAL FUND RETURN: This section provides information about actual account values and actual expenses. You may use this section to help you to estimate the actual expenses that you paid over the period after any fee waivers and expense reimbursements. The "Ending Account Value" shown is derived from the Fund's ACTUAL return during the past six months, and the "Expenses Paid During Period" shows the dollar amount that would have been paid by an investor who started with $1,000 in the Fund. You may use this information, together with the amount you invested, to estimate the expenses that you paid over the period. To do so, simply divide your account value by $1,000 (for example, an $8,600 account value divided by $1,000 = 8.6), then multiply the result by the number given for your Fund under the heading "Expenses Paid During Period" to estimate the expenses you paid during this period. HYPOTHETICAL 5% RETURN: This section provides information about hypothetical account values and hypothetical expenses based on the Fund's actual expense ratio. It assumes a hypothetical annualized return of 5% before expenses during the period shown. In this case - because the hypothetical return used is NOT the Fund's actual return - the results do not apply to your investment and you cannot use the hypothetical account value and expense to estimate the actual ending account balance or expenses you paid for the period. This example is useful in making comparisons of the ongoing costs of investing in the Fund and other funds. To do so, compare this 5% hypothetical example with the 5% hypothetical examples that appear in shareholder reports of other funds. Please note that the expenses shown in the table are meant to highlight your ongoing costs only and do not reflect any transactional costs such as sales charges (loads), redemption fees, or exchange fees, if any, which would be described in the Prospectus. If these costs were applied to your account, your costs would be higher. Therefore, the 5% hypothetical return is useful in comparing ongoing costs only, and will not help you determine the relative total costs of owning different funds. The "Annualized Expense Ratio" represents the actual expenses for the last six months and may be different from the expense ratio in the Financial Highlights which is for the year ended December 31, 2005.

ORGANIZATION. The Gabelli ABC Fund (the "Fund"), a series of Gabelli Investor Funds, Inc. (the "Corporation"), was organized on October 30, 1992 as a Maryland corporation. The Fund is a non-diversified open-end management investment company registered under the Investment Company Act of 1940, as amended (the "1940 Act"). The Fund's primary objective is to achieve total returns that are attractive to investors in various market conditions without excessive risk of capital loss. The Fund commenced investment operations on May 14, 1993. 2. SIGNIFICANT ACCOUNTING POLICIES. The preparation of financial statements in accordance with 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 of Directors (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 foreign markets are generally valued at the preceding closing values of such securities on their respective exchanges or if after the close of the foreign markets, but prior to the close of business on the day the securities are being valued, market conditions change significantly, certain foreign securities may be fair valued pursuant to procedures established by the Board. 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 valued at their fair value 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 valued at their fair value as determined in good faith under procedures established by and under the general supervision of 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. 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 10 THE GABELLI ABC FUND NOTES TO FINANCIAL STATEMENTS (CONTINUED) ================================================================================ 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 December 31, 2005, there were no open repurchase 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 fluctuation of the value of the contract. The daily changes in the contract are included in unrealized gains or losses. 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 December 31, 2005, there were no open futures contracts. SECURITIES SOLD SHORT. A short sale involves selling a security which the Fund does not own. The proceeds received for 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 the 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 Fund did not hold any short positions as of December 31, 2005. 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 December 31, 2005, there were no open forward foreign exchange contracts. FOREIGN CURRENCY TRANSLATIONS. The books and records of the Fund are maintained in United States (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 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 11 THE GABELLI ABC FUND NOTES TO FINANCIAL STATEMENTS (CONTINUED) ================================================================================ 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 salable among qualified institutional investors under special rules adopted by the Securities and Exchange Commission (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. EXPENSES. Certain administrative expenses are common to, and allocated among, various affiliated funds. Such allocations are made on the basis of each Fund's average net assets or other criteria directly affecting the expenses as determined by the Adviser pursuant to procedures established by the Board. 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 shown as "custodian fee credits". DIVIDENDS AND DISTRIBUTIONS TO SHAREHOLDERS. Dividends and distributions to 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, adjustments are made to the appropriate equity accounts in the period when the differences arise. These reclassifications have no impact on the net asset value ("NAV") of the Fund, including the Fund's use of the tax accounting practice known as equalization, and the calculation of net 12 THE GABELLI ABC FUND NOTES TO FINANCIAL STATEMENTS (CONTINUED) ================================================================================ investment income per share in the Financial Highlights excludes these adjustments. For the year ended December 31, 2005, reclassifications were made to increase accumulated distributions in excess of net investment income by $420,539 and to increase accumulated distributions in excess of net realized gain on investments by $916,684, with an offsetting adjustment to additional paid-in capital. The tax character of distributions paid during the fiscal years ended December 31, 2005 and December 31, 2004 was as follows: YEAR ENDED YEAR ENDED DECEMBER 31, 2005 DECEMBER 31, 2004 ----------------- ----------------- DISTRIBUTIONS PAID FROM: Ordinary income (inclusive of short-term capital gains) ...... $9,621,608 $5,386,566 Net long-term capital gains ...... 191,573 -- ---------- ---------- Total distributions paid ......... $9,813,181 $5,386,566 ========== ========== 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. As of December 31, 2005, the components of accumulated earnings/(losses) on a tax basis were as follows: Net unrealized appreciation ............. $2,519,735 Other temporary differences ............. (155,000) ---------- Total accumulated gain .................. $2,364,735 ========== The following summarizes the tax cost of investments and related unrealized appreciation/depreciation at December 31, 2005: GROSS GROSS NET UNREALIZED UNREALIZED UNREALIZED APPRECIATION/ COST APPRECIATION DEPRECIATION (DEPRECIATION) ---- ------------ ------------ -------------- Investments ...$158,322,769 $4,919,474 $(2,284,036) $2,635,438 3. INVESTMENT ADVISORY AGREEMENT. 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, at the annual rate of 1.00% of the value of its average daily net assets. In accordance with the Advisory Agreement, the Adviser provides a continuous investment program for the Fund's portfolio, oversees the administration of all aspects of the Fund's business and affairs, and pays the compensation of all Officers and Directors of the Fund who are affiliated persons of the Adviser. Since April 1, 2002, the Adviser has voluntarily agreed to reduce its advisory fee by 0.50%, but may increase or decrease the advisory fee rate reduction at any time. The Fund's expenses were reduced by $1,184,775 for the year ended December 31, 2005. Such amounts are not recoverable in future years. 4. DISTRIBUTION PLAN. The Board of Directors of the Fund approved the elimination of the Fund's distribution and service plan (the "Plan") adopted by the Fund pursuant to rule 12b-1 under the 1940 Act effective as of February 25, 2004. 5. PORTFOLIO SECURITIES. Purchases and proceeds from the sales of securities for the year ended December 31, 2005, other than short-term securities, aggregated $380,133,040 and $149,151,427, respectively. 6. TRANSACTIONS WITH AFFILIATES. During the year ended December 31, 2005, the Fund paid brokerage commissions of $226,313 to Gabelli & Company. 13 THE GABELLI ABC FUND NOTES TO FINANCIAL STATEMENTS (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. During the year ended December 31, 2005, the Fund reimbursed the Adviser $45,000 in connection with the cost of computing the Fund's NAV, which is included in miscellaneous expenses in the Statement of Operations. 7. LINE OF CREDIT. The Fund has access to an unsecured line of credit of up to $25,000,000 from the custodian for temporary borrowing purposes. Borrowings under this arrangement bear interest at 0.75% above the Federal Funds rate on outstanding balances. During the year ended December 31, 2005, there were no borrowings from the line of credit. 8. CAPITAL STOCK TRANSACTIONS. Transactions in shares of capital stock were as follows: YEAR ENDED YEAR ENDED DECEMBER 31, 2005 DECEMBER 31, 2004 ----------------------------- --------------------------- SHARES AMOUNT SHARES AMOUNT ----------- ------------- ---------- ------------ Shares sold ................... 593,644 $ 5,899,245 5,283,745 $ 52,102,231 Shares issued upon reinvestment of dividends .. 640,813 6,305,599 396,288 3,899,474 Shares redeemed ...............

(12,603,850) $(126,289,556) 666,535 $ 6,506,698 =========== ============= ========== ============ Effective June 15, 2005 the Fund imposed a redemption fee of 2.00% on Fund shares that are redeemed or exchanged on or before the seventh day after the date of a purchase. (From November 1, 2004 through June 14, 2005, the Fund imposed a redemption fee on shares that were redeemed or exchanged within the sixtieth day after the date of a purchase.) The redemption fee is deducted from the proceeds otherwise payable to the redeeming shareholders and is retained by the Fund. The redemption fees retained by the Fund during the years ended December 31, 2005 and December 31, 2004 amounted to $332 and $27, respectively. The redemption fee does not apply to shares purchased through programs that the Adviser determined to have appropriate short-term trading policies in place. Additionally, certain recordkeepers for qualified and non-qualified retirement plans that could not collect the redemption fee at the participant level due to systems limitations have received an extension to implement such systems. 9. 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. 10. OTHER MATTERS. The Adviser and/or affiliates have received subpoenas from the Attorney General of the State of New York and the SEC requesting information on mutual fund trading practices involving certain funds managed by the Adviser. GAMCO Investors, Inc., the Adviser's parent company, is responding to these requests for documents and testimony. 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. 14 THE GABELLI ABC FUND FINANCIAL HIGHLIGHTS ================================================================================ Selected data for a share of capital stock outstanding throughout each period: YEAR ENDED DECEMBER 31, -------------------------------------------------------- 2005 2004 2003 2002 2001 ------ ------ ------ ------ ------ OPERATING PERFORMANCE: Net asset value, beginning of period .................. $ 9.85 $ 9.83 $ 9.64 $ 9.65 $ 9.45 -------- -------- -------- -------- -------- Net investment income ................................. 0.17 0.08 0.05 0.07 0.10 Net realized and unrealized gain on investments ....... 0.32 0.11 0.43 0.01 0.33 -------- -------- -------- -------- -------- Total from investment operations ...................... 0.49 0.19 0.48 0.08 0.43 -------- -------- -------- -------- -------- DISTRIBUTIONS TO SHAREHOLDERS: Net investment income .................................

(b) Amount represents less than $0.005 per share. (c) The ratios do not include a reduction of expenses for custodian fee credits on cash balances maintained with the custodian. Including such custodian fee credits, the expense ratio for the year ended December 31, 2005 would be 0.62%. See accompanying notes to financial statements. 15 THE GABELLI ABC FUND REPORT OF INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM ================================================================================ To the Shareholders and Board of Directors of Gabelli Investor Funds, Inc. We have audited the accompanying statement of assets and liabilities, including the schedule of investments, of The Gabelli ABC Fund (the "Fund"), a series of Gabelli Investor Funds, Inc., as of December 31, 2005, and the related statement of operations for the year then ended, the statements of changes in net assets for each of the two years in the period then ended, and financial highlights for each of the three years in the period then ended. These financial statements and financial highlights are the responsibility of the Fund's management. Our responsibility is to express an opinion on these financial statements and financial highlights based on our audits. The financial highlights for each of the two years in the period ended December 31, 2002 were audited by other auditors whose report dated January 31, 2003, expressed an unqualified opinion on those financial statements. We conducted our audits in accordance with the standards of the Public Company Accounting Oversight Board (United States). Those standards require that we plan and perform the audit to obtain reasonable assurance about whether the financial statements and financial highlights are free of material misstatement. We were not engaged to perform an audit of the Fund's internal control over financial reporting. Our audits included consideration of internal control over financial reporting as a basis for designing audit procedures that are appropriate in the circumstances, but not for the purpose of expressing an opinion on the effectiveness of the Fund's internal control over financial reporting. Accordingly, we express no such opinion. An audit also includes examining, on a test basis, evidence supporting the amounts and disclosures in the financial statements and financial highlights, assessing the accounting principles used and significant estimates made by management, and evaluating the overall financial statement presentation. Our procedures included confirmation of securities owned as of December 31, 2005, by correspondence with the Fund's custodian. We believe that our audits provide a reasonable basis for our opinion. In our opinion, the financial statements and financial highlights referred to above present fairly, in all material respects, the financial position of The Gabelli ABC Fund, a series of Gabelli Investor Funds, Inc., at December 31, 2005, the results of its operations for the year then ended, the changes in its net assets for each of the two years in the period then ended, and the financial highlights for each of the three years in the period then ended, in conformity with U.S. generally accepted accounting principles. /s/ ERNST & YOUNG LLP Philadelphia, Pennsylvania February 14, 2006 16 THE GABELLI ABC FUND ADDITIONAL FUND INFORMATION (UNAUDITED) ================================================================================ The business and affairs of the Fund are managed under the direction of the Fund's Board of Directors.

Effective November 16, 2005, Mr. Karl Otto Pohl resigned from the Board of Directors and now serves as Director Emeritus. 3 "Interested person" of the Fund as defined in the Investment Company Act of 1940. Mr. Gabelli is considered an "interested person" because of his affiliation with Gabelli Funds, LLC which acts as the Fund's investment adviser. 4 This column includes only directorships of companies required to report to the SEC under the Securities Exchange Act of 1934 (i.e. public companies) or other investment companies registered under the 1940 Act. - -------------------------------------------------------------------------------- 2005 TAX NOTICE TO SHAREHOLDERS (Unaudited) For the fiscal year ended December 31, 2005, the Fund paid to shareholders an ordinary income dividend (comprised of net investment income and short-term capital gains) totaling $0.48 and a distribution from long-term capital gain totaling $0.01 per share which is designated as a capital gain dividend. For the fiscal year ended December 31, 2005, 6.46% of the ordinary income dividend qualifies for the dividend received deduction available to corporations, and 11.06% of the ordinary income distribution was qualified dividend income. U.S. GOVERNMENT INCOME: The percentage of the ordinary income dividend paid by the Fund during fiscal year 2005 which was derived from U.S. Treasury securities was 22.94%. Such income is exempt from state and local tax in all states. However, many states, including New York and California, allow a tax exemption for a portion of the income earned only if a mutual fund has invested at least 50% of its assets at the end of each quarter of the Fund's fiscal year in U.S. Government securities. The Gabelli ABC Fund did not meet this strict requirement in 2005. Due to the diversity in state and local tax law, it is recommended that you consult your personal tax advisor as to the applicability of the information provided to your specific situation. - -------------------------------------------------------------------------------- 18 - -------------------------------------------------------------------------------- GABELLI FUNDS AND YOUR PERSONAL PRIVACY ================================================================================ WHO ARE WE?

The Audit Committee ("Committee") of the registrant is responsible for pre-approving (i) all audit and permissible non-audit services to be provided by the independent auditors to the registrant and (ii) all permissible non-audit services to be provided by the independent auditors to the Adviser, Gabelli Funds, LLC, and any affiliate of Gabelli Funds, LLC ("Gabelli") that provides services to the registrant (a "Covered Services Provider") if the independent auditors' engagement related directly to the operations and financial reporting of the registrant. The Committee may delegate its responsibility to pre-approve any such audit and permissible non-audit services to the Chairperson of the Committee, and the Chairperson must report to the Committee, at its next regularly scheduled meeting after the Chairperson's pre-approval of such services, his or her decision(s). The Committee may also establish detailed pre-approval policies and procedures for pre-approval of such services in accordance with applicable laws, including the delegation of some or all of the Committee's pre-approval responsibilities to the other persons (other than Gabelli or the registrant's officers). Pre-approval by the Committee of any permissible non-audit services is not required so long as: (i) the aggregate amount of all such permissible non-audit services provided to the registrant, Gabelli and any Covered Services Provider constitutes not more than 5% of the total amount of revenues paid by the registrant to its independent auditors during the fiscal year in which the permissible non-audit services are provided; (ii) the permissible non-audit services were not recognized by the registrant at the time of the engagement to be non-audit services; and (iii) such services are promptly brought to the attention of the Committee and approved by the Committee or Chairperson prior to the completion of the audit.

(h) The registrant's audit committee of the board of directors has considered whether the provision of non-audit services that were rendered to the registrant's investment adviser (not including any sub-adviser whose role is primarily portfolio management and is subcontracted with or overseen by another investment adviser), and any entity controlling, controlled by, or under common control with the investment adviser that provides ongoing services to the registrant that were not pre-approved pursuant to paragraph (c)(7)(ii) of Rule 2-01 of Regulation S-X is compatible with maintaining the principal accountant's independence.
