Stone ("Mr. Stone") with the Securities and Exchange Commission on August 3, 2005, (the "Schedule 13D"), relating to shares of common stock, $.01 par value per share (the "Common Stock") of SS&C Technologies, Inc., a Delaware corporation ("SS&C" or the "Issuer"). Mr. Stone's beneficial ownership of shares of Common Stock, as set forth in the previously filed Schedule 13D, represented 6,353,270 shares of Common Stock, including 481,250 shares issuable upon the exercise of options that Mr. Stone had the right to exercise within 60 days thereof. As set forth in the Schedule 13D, Sunshine Acquisition Corporation, a Delaware Corporation ("Parent"), and Sunshine Merger Corporation, a Delaware Corporation and wholly owned subsidiary of Parent ("Merger Co"), entered into an Agreement and Plan of Merger, dated July 28, 2005, as amended on August 25, 2005 (the "Merger Agreement") whereby Merger Co would be merged with and into SS&C, resulting in SS&C as the surviving corporation (the "Merger"). In connection therewith, Mr. Stone entered into a Voting Agreement, dated as of July 28, 2005, and Contribution and Subscription Agreement dated as of July 28, 2005, (the "Contribution and Subscription Agreement"), each described in the previously filed Schedule 13D and attached as exhibits thereto. On November 23, 2005, upon consummation of the Merger and pursuant to the terms of the Contribution and Subscription Agreement, Mr. Stone contributed 3,921,958 shares of Common Stock in exchange for newly issued shares of common stock, par value $0.01 per share, of Parent, representing approximately 28% of the outstanding equity of Parent. Also pursuant to the Merger, subject to the terms and conditions of the Merger Agreement, each remaining share of Common Stock owned by Mr. Stone (excluding 14,000 shares transferred as a bona fide gift on November 22, 2005) was converted into the right to receive $37.25 in cash and all of Mr. Stone's outstanding options were converted into options to purchase equity in the Parent. Therefore, as of November 23, 2005, Mr. Stone no longer beneficially owns any Common Stock of the Issuer. Item 5 of the Schedule 13D is amended and supplemented as follows: Item 5. Interest in Securities of the Issuer (a) As of November 23, 2005, Mr. Stone directly owns 0 shares of Common Stock. (b) Not Applicable. (c) Except as described in this Amendment, the Reporting Person has not engaged in any transactions in the Common Stock during the 60 days preceding the date of this Schedule 13D. (d) Not Applicable. (e) Not Applicable. SIGNATURES After reasonable inquiry and to the best of my knowledge and belief, I certify that the information set forth in this statement is true, complete and correct.
