Item 8.01. Other Events.

On March 14, 2012, SS&C Technologies Holdings Europe S.A.R.L. (“SS&C Sarl”), a Luxembourg société à responsabilité limitée and an indirect wholly-owned subsidiary of SS&C Technologies Holdings, Inc. (“SS&C”), entered into a cooperation agreement (the “Cooperation Agreement”) with GlobeOp Financial Services S.A. (“GlobeOp”), a Luxembourg sociéte anonyme. Pursuant to the Cooperation Agreement, SS&C Sarl announced pursuant to Rule 2.7 of the City Code on Takeovers and Mergers the terms of a recommended cash offer under which SS&C, acting through SS&C Sarl, would acquire the entire issued and to be issued share capital of GlobeOp for 485 pence per share (the “Offer”). The full terms of, and conditions to, the Offer are set forth in the offer document issued by SS&C Sarl on March 26, 2012 (the “Offer Document”).

On May 15, 2012, SS&C issued a press release relating to the Offer announcing that as of 1:00 p.m. (London time) on May 14, 2012, SS&C Sarl had received valid acceptances of the Offer in respect of 82,663,536 GlobeOp shares, representing approximately 76.8 percent of the existing issued share capital of GlobeOp. Accordingly, the Acceptance Condition has now been satisfied and the Offer is unconditional as to acceptances.

The Offer, which remains subject to the terms and conditions set out in the Offer Document, including a number of outstanding regulatory clearances, will remain open until further notice and at least 14 days’ notice will be given prior to the closing of the Offer.

As previously reported on April 3, 2012, SS&C Sarl has received early termination of the waiting period under the Hart-Scott-Rodino Antitrust Improvements Act of 1976. In addition, the Financial Industry Regulatory Authority has now granted approval of an indirect change in ownership of GlobeOp Markets Limited.

A copy of the full press release is attached hereto as Exhibit 99.1. The information in Exhibit 99.1 shall not be deemed filed for purposes of Section 18 of the Securities Exchange Act of 1934, as amended, or otherwise subject to the liabilities of that section, nor shall it be deemed to be incorporated by reference in any filing under the Securities Act of 1933, as amended, irrespective of any general incorporation language.
