DEXTER, MI and BRENTWOOD, TN - Thomson Tax & Accounting, a part of The Thomson Corporation (NYSE: TOC; TSX: TOC), and Capital Confirmation, Inc. (CCI), a leader in online authentication and authorization services, are working together to provide users of Engagement CS with direct access to Capital Confirmation's CONFIRM™ technology. CONFIRM technology provides a fully automated confirmation process. Integration with CONFIRM allows Engagement CS users to perform secure online confirmations directly from the Engagement CS workspace.

"We are very excited to be working with Capital Confirmation to offer our Engagement CS customers direct access to CCI's industry-leading CONFIRM technology," stated Teresa Mackintosh, Vice President of Strategic Marketing at Thomson Tax & Accounting, Professional Software & Services. "The ability to automate the confirmation process will enhance efficiency and further streamline the engagement process."

CONFIRM technology provides an effective automated confirmation process that ensures privacy and security of confirmation communications and offers a sound infrastructure for authenticating all parties involved in the confirmation. Direct access to validated responders increases the reliability of the confirmation response and has been shown to significantly improve efficiency through shortened turnaround times. <

"The opportunity to allow seamless access to the CONFIRM service through the innovative Engagement CS product is a major step forward for the accounting profession. As confirmations continue to take a higher profile, the need for a secure and efficient solution is critical. Thomson Tax & Accounting and CCI have accomplished this,” said Chris Schellhorn, CEO at Capital Confirmation, Inc.

"There are several benefits associated with an automated confirmation process," said Brian Vroom, Vice President of Development at Thomson Tax & Accounting, Professional Software & Services. "The value to our users is realized through reduced risk of confirmation fraud and enhanced engagement efficiency. Additionally, with an ongoing effort to combat fraud, electronic confirmations may very well become a state requirement. If this happens, those who adopt the electronic confirmation process today will be ahead of the game in complying with state mandates."

Engagement CS is part of the CS Professional Suite, the broadest line of integrated tax and accounting software and services serving the tax and accounting profession.
