[GRAPHIC OMITTED] THE GABELLI MATHERS FUND ANNUAL REPORT DECEMBER 31, 2004 THE GABELLI MATHERS FUND ANNUAL REPORT DECEMBER 31, 2004 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 portfolio 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, 2004 with a description of the factors that affected the performance during the past year. Sincerely yours, /s/ Bruce N. Alpert Bruce N. Alpert Executive Vice President February 23, 2005 PERFORMANCE DISCUSSION The Fund's portfolio remained conservatively invested at year end, with a gross stock exposure of 22.4% of assets, comprised of 10.7% longs and 11.7% shorts, with the remainder in cash, awaiting lower risk entry points to initiate new and larger capital commitments. This compares to a 10.3% gross stock exposure at year-end 2003, comprised of 6.4% long and 3.9% short individual securities. Both the long stock segment of the portfolio and the fixed income portion, which was limited to short-term U.S. Treasury bills and U.S. Treasury collateralized repurchase agreements, added to the Fund's total return in 2004. The short equity segment had a negative return and was the primary factor, along with negative real short-term interest rates, for the Fund's 2004 performance. During the year, a portion of the Fund's common stock segment was invested in takeover-target companies subject to friendly, all cash tender or merger offers from acquiring companies. The Fund purchased these event-driven stocks after the deals were publicly announced, generally by financially strong, strategic buyers. Deal arbitrage stocks typically earn relatively attractive annualized returns, but are held for short time periods resulting in a disproportionately high portfolio turnover rate, which can be misleading. This occurs when the Fund's fixed income position is a relatively high proportion of assets and has a maturity of less than one year, while the percent invested in stocks is low.

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 are 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, 2004.

ORGANIZATION. The Gabelli Mathers Fund (the "Fund") was organized on June 17, 1999 as a Delaware statutory trust. The Fund commenced investment operations on October 1, 1999 as the successor to the Mathers Fund, Inc. (the "Mathers Fund") which was organized on March 31, 1965 as a Maryland corporation. The Mathers Fund commenced investment operations on August 19, 1965. The Fund is a 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 long-term capital appreciation. 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 Trustees (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 that are not credit impaired with remaining maturities of 60 days or less 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 latest average of the 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. 8 THE GABELLI MATHERS FUND NOTES TO FINANCIAL STATEMENTS (CONTINUED) - -------------------------------------------------------------------------------- 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. 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 in 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. At December 31, 2004, there were no open futures contracts. There are several risks in connection with the use of futures contracts as a hedging device. 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. 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. Securities sold short at December 31, 2004 are reflected in the Schedule of Investments. 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 as earned. Dividend income is recorded on the ex-dividend date. 9 THE GABELLI MATHERS FUND NOTES TO FINANCIAL STATEMENTS (CONTINUED) - -------------------------------------------------------------------------------- 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. DIVIDENDS AND DISTRIBUTIONS TO SHAREHOLDERS. Dividends and distributions to shareholders are recorded on the ex-dividend date. Distributions to shareholders are based on ordinary income and long-term 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 held by the Fund, timing differences and differing characterizations of distributions made by the Fund. No distributions were made in the fiscal years ended December 31, 2004 and 2003. 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 that the differences arise. For the year ended December 31, 2004, reclassifications were made to decrease accumulated net investment loss by $292,952 and to decrease accumulated net realized loss on investments by $22,226,886, with an offsetting adjustment to additional paid-in capital. These reclassifications have no impact on the net asset value of the Fund and the calculation of net investment income per share in the financial highlights excludes these adjustments. 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 Fund's policy 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, 2004, the components of earnings/(losses) on a tax basis were as follows: Capital loss carryforward ................................. $(21,245,902) Net unrealized appreciation/(depreciation) of investments.. 515,810 Net unrealized appreciation/(depreciation) of securities sold short .............................................. (762,239) ------------ Total accumulated loss .................................... $(21,492,331) ============ The Fund has a net capital loss carryforward for Federal income tax purposes at December 31, 2004 of $21,245,902. This capital loss carryforward is available to reduce future required distributions of net capital gains to shareholders. $22,226,886 of the loss carryforward expired in 2004; $7,869,968 is available through 2006; $12,430,175 is available through 2010; $670,201 is available through 2011; and $275,558 is available through 2012. 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 the Fund's 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 Trustees of the Fund who are its affiliates. 10 THE GABELLI MATHERS FUND NOTES TO FINANCIAL STATEMENTS (CONTINUED) - -------------------------------------------------------------------------------- 4. DISTRIBUTION PLAN. The Fund's Board has adopted a distribution plan (the "Plan") pursuant to Rule 12b-1 under the 1940 Act. For the year ended December 31, 2004, the Fund incurred distribution costs payable to Gabelli & Company, Inc., an affiliate of the Adviser, of $119,309, or 0.25% of average daily net assets, the annual limitation under the Plan. Such payments are accrued daily and paid monthly. 5. PORTFOLIO SECURITIES. Purchases and proceeds from the sales of securities for the year ended December 31, 2004, other than short term securities, aggregated $6,325,877 and $5,382,191, respectively. 6. TRANSACTIONS WITH AFFILIATES. During the year ended December 31, 2004, the Fund paid brokerage commissions of $8,800 to Gabelli & Company, Inc. The cost of calculating the Fund's net asset value per share is a Fund expense pursuant to the Advisory Agreement between the Fund and the Adviser. During the year ended December 31, 2004, the Fund reimbursed the Adviser $8,700 in connection with the cost of computing the Fund's net asset value, which is included in miscellaneous expenses in the Statement of Operations. 7. SHARES OF BENEFICIAL INTEREST. Transactions in shares of beneficial interest were as follows: YEAR ENDED YEAR ENDED DECEMBER 31, 2004 DECEMBER 31, 2003 -------------------------- ------------------------- SHARES AMOUNT SHARES AMOUNT Shares sold ....... 239,007 $ 2,532,625 271,933 $ 2,922,779 Shares redeemed ...(2,043,820) (21,552,931) (2,007,763) (21,421,382) ---------- ------------ --------- ------------ Net decrease ...(1,804,813) $(19,020,306) (1,735,830) $(18,498,603) ========== ============ ========= ============ The Fund imposed a redemption fee of 2.00% on shares that are purchased on or after November 1, 2004, and redeemed or exchanged within 60 days 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 fee did 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 until March 31, 2005 to implement such systems. 8. 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 shares trading practices. Gabelli Asset Management Inc. is responding to these requests. The Fund does not believe that these matters will have a material adverse effect on the Fund's financial position or the results of its operations. 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. 11 THE GABELLI MATHERS FUND NOTES TO FINANCIAL STATEMENTS (CONTINUED) - -------------------------------------------------------------------------------- 10.

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. 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. An audit includes 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, 2004, by correspondence with the Fund's custodian and brokers or by other appropriate auditing procedures where replies from brokers were not received. 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 Mathers Fund at December 31, 2004, 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 five years in the period then ended, in conformity with U.S. generally accepted accounting principles. /s/ ERNST & YOUNG LLP New York, New York February 11, 2005 13 THE GABELLI MATHERS FUND ADDITIONAL FUND INFORMATION (UNAUDITED) - -------------------------------------------------------------------------------- The business and affairs of the Fund are managed under the direction of the Fund's Board of Trustees.

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.
