Thomson Financial Releases Thomson PORTIA v8.0

NEW YORK, NY, 09/19/2006, Thomson Financial, an operating unit of The Thomson Corporation (NYSE: TOC, TSX: TOC) and leading provider of information and technology solutions to the worldwide financial community, announces the launch of Thomson PORTIA v8.0, including several enhancements to the industry’s leading portfolio management system.

This new release broadens the scope of Thomson PORTIA by adding significant new functional and technical capabilities that extend Thomson PORTIA’s support for the needs of the middle and back office. The enhanced version of Thomson PORTIA is the most scalable to date, to support continued customer growth in account levels and transaction volumes and business expansion into new regions and business lines; PORTIA offers unprecedented support to a global enterprise organization and aids compliance with regulatory guidelines .

Christen Bremner, Senior Vice President Thomson Financial commented: “Many of our customers are already leveraging Thomson PORTA to not only manage their traditional institutional business but have expanded its use to support retail, individual, private client and high net worth accounts and business lines. The enterprise-wide functionality embedded within the new version of Thomson PORTIA offers significant benefits to the client, helping them run multiple, if not all, business lines on the same portfolio management system.”

Thomson PORTIA v8.0 was developed with significant involvement from clients during both the development and testing process.

Russell Martin, Senior Financial Systems Architect, Segall Bryant & Hamill Investment Councel added: “As we continue to grow, it is increasingly important that our software systems help our focused team become as efficient as possible. This goal was one of the primary motivators in our decision to participate in the Thomson PORTIA 8.0 Early Adopter Program. We saw it as a unique opportunity to not only take advantage of some extremely helpful features being made available in the base product and the new modules, but to actually have some input during the design phase of those new features.”

Thomson PORTIA v8.0 has also made significant advancements in driving an optimized workflow. These include:

* Corporate Actions – the new corporate actions processing module reduces the time and risk associated with manual entry and processing of corporate actions events by offering a centralized and efficient corporate actions workflow, flexible processing options, automated feeds and support for new corporate action types
* Regulatory compliance - to help clients meet regulatory mandates, the advanced security functionality of PORTIA ACCESS (Application aCCess and Enhanced Security Solution) enhances the PORTIA “Login Process” to help client comply with Sarbanes-Oxley and ISO 17799 standards.
