Item 5.07                                           Submission of Matters to a Vote of Securities Holders.

On April 14, 2015, Advent Software, Inc. (“Advent”) held a special meeting of stockholders (the “Special Meeting”) at Advent’s principal executive offices in San Francisco, CA.

As of the record date, February 27, 2015, there were 52,586,892 shares of common stock of Advent eligible to be voted at the Special Meeting.  At the Special Meeting, 45,401,621 shares, or approximately 86.33% of all outstanding shares of common stock, were present either in person or by proxy.  Three matters were voted upon at the special meeting, with the Board of Directors of Advent recommending a vote “FOR” in connection with each of the proposals voted upon, as further described in the definitive proxy statement filed with the Securities and Exchange Commission on March 3, 2015 (the “Definitive Proxy Statement”).

Proposal No. 1 (the “Merger Proposal”) was to consider and vote on the proposal to adopt the Agreement and Plan of Merger, dated as of February 2, 2015 (the “Merger Agreement”) by and among Advent, SS&C Technologies Holdings, Inc. (“SS&C”) and Arbor Acquisition Company, Inc. (“Merger Sub”), pursuant to which Merger Sub will merge with and into Advent (the “Merger”), and Advent will become a wholly owned subsidiary of SS&C.

Proposal No. 2 (the “Adjournment Proposal”) was to consider and vote on any proposal to adjourn the Special Meeting to a later date or dates if necessary or appropriate to solicit additional proxies if there were insufficient votes to adopt the Merger Agreement at the time of the Special Meeting.

Proposal No. 3 (the “Merger Compensation Proposal”) was to consider and vote on the proposal to approve, on a non-binding, advisory basis, compensation that will or may become payable to Advent’s named executive officers in connection with the Merger.

The Merger Proposal, Adjournment Proposal and the Merger Compensation Proposal were approved.  The table below shows the final voting results from the Special Meeting.
