Tower Asset Management Adopts Advent Portfolio Exchange®

Tower Asset Management Adopts Advent Portfolio Exchange®, Delivers Global Reach and Greater Efficiency

New York, San Francisco, May 1, 2006 – Advent Software, Inc. (NASDAQ:ADVS), the leading provider of software and services to the investment management industry, today announced that Tower Asset Management, a Beverly Hills-based asset management firm, implemented Advent Portfolio Exchange® for enhanced reporting,  client service and global contact management capabilities.

“With Advent Portfolio Exchange®, the big advantage lies in having open access to all our data. We can now view and extract data anytime we want,” said Anton Pereiaslavtsev, Vice President, Information Systems at Tower Asset Management. “The migration from Axys® to Advent Portfolio Exchange® included an analysis of our portfolio history and opportunities to improve existing workflows. Advent’s implementation and project management methodology helped us understand how to make our operations more efficient. After implementing Advent Portfolio Exchange®, our daily processing is 20 to 25 percent more efficient.”

“Tower Asset Management’s goal for the future is to be able to create a mobile and geographically diverse sales force without expanding our office space,” said Pereiaslavtsev. “The best way to achieve that goal is through using a browser-based platform that can be accessed from any place in the world through a secure VPN.”

Advent Portfolio Exchange® is a browser-based end-to-end portfolio management platform that integrates portfolio management with front-office marketing and CRM functions, as well as back-office portfolio accounting and reporting operations.

“As our clients’ practices expand to global relationships, we are able to offer them advanced portfolio management solutions with worldwide access to critical portfolio and client information,” said William Penney, Senior Director of Product Marketing at Advent Software. “We’re proud to contribute to Tower’s ability to improve their service to clients and develop new business.”

Tower Asset Management, founded in 1991, caters to high-net-worth individuals and families, with $440 million under management. Tower was previously using Advent’s Axys® platform but needed enhanced reporting tools and greater access to data.

Advent Software, Inc., a multi-national company, has been providing trusted solutions to the world's leading financial professionals since 1983. Firms in more than 60 countries using Advent technology manage investments totaling more than US $12 trillion. Advent's quality software, data and services enable financial professionals to improve service and communication to their clients, allowing them to grow their business while controlling costs.
