TABLE OF CONTENTS

ITEM 8.01 Other Events

During fiscal year 2002, Advent Software, Inc. (the “Company”) acquired approximately 16% of the outstanding shares of LatentZero Limited (“LatentZero”), a privately held company in the United Kingdom. On April 16, 2007, the Company, together with other LatentZero shareholders, entered into a conditional agreement to sell their ownership in LatentZero to royalblue group plc. The maximum possible consideration to the Company from the sale of its ownership interest in LatentZero is approximately $17 million, comprised of initial consideration of approximately $10 million, payable at completion of the sale transaction and subject to certain closing contingencies and fees, and up to an aggregate $7 million of deferred contingent consideration for fiscal years 2007 and 2008. For fiscal 2007 and 2008, the payment of the deferred contingent consideration is dependent on the achievement of performance objectives related to revenue and operating profit. Consideration is denominated in Pounds Sterling (GBP) in the conditional agreement and the actual amounts of consideration in U.S. dollars to be received by the Company may differ depending on foreign exchange rates at the time of payment. The sale transaction is anticipated to be completed during the second quarter of 2007.
