The Gabelli ABC Fund will re-open to new investors on March 1, 2004, in anticipation of increasing merger and acquisition activity.

The Gabelli ABC Fund has been up each calender year since its inception on May 14, 1993. It returned 4.94% during 2003, and for the three, five and ten-year periods ended December 31, 2003, its average annual total returns were 3.44%, 5.99% and 7.70%, respectively.

The Fund will reopen on March 1, 2004, subject to the following limitations: the minimum initial investment will be $50,000 and the purchase may only be made through Gabelli & Company, Inc., the Fund’s principal distributor, or directly through the Fund’s transfer agent. Investments through other intermediaries will not be accepted.

Gabelli ABC Fund began investment operations on May 14, 1993. As an incentive to attract investors wary of the market, the Fund offered a unique one-year performance guarantee of at least 6% on a $2,000 investment. In 1994, 1995 and 1996, the Fund offered a minimum 5% return on an investment of up to $5,000 for all new and current shareholders. After 1996, the performance guaranty program was eliminated. As stated above the Fund has enjoyed positive total returns in every calendar year of its existence. Because of a low level of merger and acquisition activity and a subsequent buildup of cash in the portfolio, the investment adviser voluntarily waived 50 basis points of its advisory fee on April 1, 2002, resulting in advisory fees being lowered to 50 basis points.

As of January 1, 2003, Gabelli & Company, Inc. (the “Distributor”) voluntarily waived receipt of the 25 basis points Rule 12b-1 distribution fee from the Fund, resulting in a waiver of fees currently totaling 75 basis points. The fee waivers will continue until the Fund becomes more fully invested. Subject to approval by the Fund’s Board of Directors, the Distributor intends to eliminate the 12b-1 plan.

The Fund’s adviser is Gabelli Funds, LLC, a wholly owned subsidiary of Gabelli Asset Management Inc. (NYSE; GBL), which manages, through its subsidiaries, approximately $27.6 billion.

Past performance does not guarantee future results. Total returns and average annual returns are histor - ical and reflect changes in share price, reinvested dividends and capital gains and are net of expenses. Investment results and the principal value of an investment will fluctuate. When shares are redeemed, they may be worth more or less than their original cost. Results for 2002 and 2003 would have been lower if fees had not been waived since April 2002. Current performance may be lower or higher than the performance data presented.
