SAN FRANCISCO – June 9, 2009 – Advent Software, Inc. (NASDAQ: ADVS), a leading provider of software and services for the global investment management industry, today announced that it has signed more than 400 client contracts for the use of Advent Portfolio Exchange® (APX) through on-site installation or Advent's outsourced offerings, since the product was launched in late 2005.  APX is Advent’s award-winning end-to-end portfolio management solution that integrates the front-office functions of prospecting, marketing, and customer relationship management with the back-office operations of portfolio accounting and reporting. 

Advent clients can choose from a wide range of flexible deployment options for APX, including on-site installation, managed hosting or a fully outsourced environment with reporting and reconciliation services.  The 400 APX clients are comprised of a wide range of investment management firms in 30 countries, including asset managers, family offices, independent advisors, trusts, broker dealers and hedge funds, managing assets from $25 million to over $75 billion.

"In today's environment, end-to-end portfolio management systems are a strategic imperative for the investment management community,” notes Celent Analyst Dr. Isabel Schuerte.  “Guided by the need to enhance operational efficiency, and reduce costs and operational risks, many buy side CTOs and COOs are revisiting their technology infrastructure in a bid to integrate their often heterogeneous systems environment in the front and back office."
