Exchange Data International Announces Agreement with Advent

Advent incorporates Exchange Data International’s Worldwide Equities and Fixed Income Corporate Actions into its Straight-Through-Processing Service

London - September 25, 2008 – Exchange Data International (EDI), a well-established provider of reference and corporate actions data, announced today an agreement with Advent Software, Inc. (NASDAQ: ADVS), a leading provider of software and services for the investment management industry. EDI will provide comprehensive Worldwide Equities and Fixed Income Corporate Actions data to Advent clients using Advent Corporate Actions® (ACA), Advent’s straight-through-processing service. This is Advent’s third international data vendor available through ACA.

ACA delivers customized, position-level corporate action reports for a broad range of action and security types, along with market effective transactions for mandatory U.S. equity and ADR events, including tax compliant details. Using ACA, firms can: track actions from announcement through effective date; receive alerts containing revisions and processing tips; and gain access to a dedicated team of corporate action specialists who assist advisory staff with processing details and the interpretation and confirmation of complex tax opinions.

Advent added both EDI's Worldwide and Fixed Income Corporate Actions Service to its ACA offering. With data sourced directly from all of the world’s major stock exchanges, the Worldwide Corporate Actions service provides up-to-date and accurate equity-based corporate actions information, and provides coverage on over 150 International Exchanges, with detailed announcements on over 50 corporate actions event types. EDI’s Fixed Income Corporate Actions Service follows corporate actions events on nearly 400,000 bonds from 100 countries and Supranationals. In addition to interest payments (both fixed and floating), the fixed income service covers additional specialised event types. The data is sourced from stock exchanges, central banks, ministries of finance, paying and transfer agents.

“We are very excited about our new relationship with Advent, as it brings EDI’s data to a new audience,” said Kevin Brady, Executive Director for Exchange Data International. “Advent is a leader in their space, and this relationship demonstrates EDI’s commitment to building strong relationships with market leaders to provide the industry with high standard services.”

“We are delighted to be working with EDI in order to expand our international data offering,” said Alison Swabowicz, Senior Straight-Through-Processing Product Manager at Advent. “Recently we have seen increased interest in international corporate action data; and as we've seen more clients diversify into international markets, it has become apparent the importance for Advent to maximize coverage across a wide range of countries and corporate action types.”

Advent currently has over 325 ACA clients. ACA’s user base includes clients using Advent's portfolio management and accounting platforms – Advent Portfolio Exchange®, Geneva® and Axys®, as well as clients using other products.
