Lotsoff Capital Management Chooses Thomson PORTIA Perform

New, Enhanced Version Allows for Easy Integration, Flexible Reporting Capability and Extended Composite Functionality.

New York, NY, 02/27/2006, Thomson Financial, an operating unit of The Thomson Corporation (TSX: TOC, NYSE: TOC) and leading provider of information and technology solutions to the worldwide financial community, today announced that PORTIA Perform, its global performance measurement and risk reporting tool, has been selected by Lotsoff Capital Management, a Chicago-based firm managing $5.5 billion in assets across equity, fixed income, and alternative portfolios for a primarily institutional client base.

“We were in need of a performance measurement and composite solution that could be delivered in a format that worked seamlessly with our portfolio accounting system environment. PORTIA Perform was the best choice for Lotsoff Capital Management because of its real-time integration with PORTIA,” said Gina Ehrlich, Managing Director, Information Systems. “Perform offers us the ability to run large quantities of performance data faster, create rule-based composites and warehouse historical returns and benchmarks. The system is intuitive and offers our financial analysts efficiencies that did not exist before.”

Lotsoff will be using the recently enhanced version of PORTIA Perform. The new features broaden the scope of PORTIA Perform by adding significant functional and technical capabilities. The new version includes:

* Security Segment Tracking: this feature provides the ability to historically track assets moving between segments. As a security’s attribute(s) change over time, PORTIA Perform will maintain a history of these changes and accurately reflect the asset’s segment within each time period.
* Holdings and Transaction Reports: users now have the ability to run holdings and transaction reports within PORTIA Perform allowing reports to be generated in standard html, csv or XML formats and providing users with an alternative to running reports from their portfolio management or accounting system.
* Automated Handling of Back-dated Transactions: new rules have been added that allow users to specify how PORTIA Perform will process backdated transactions, ranging from reflecting the transaction in the current period to automatically re-processing the transaction in the back-dated period.
* Unlimited Benchmarks available in reports: now users can choose to measure their portfolio or composite returns against an unlimited number of benchmarks. The benchmark returns can be compared to the total portfolio or composite returns, segment level or security level returns.

“This new, enhanced version of PORTIA Perform advances the product’s core capabilities while adding brand new functionality and customization options,” said Christen Bremner, senior vice president, Thomson Financial. “We are excited that PORTIA Perform was such a good match for Lotsoff’s performance measurement and composite needs and we are looking forward to getting them live into production.”
