This document includes summary financial information and should not be considered a substitute for our full financial statements, including footnotes, management/auditors’ reports, and related management’s discussion and analysis (MD&A). You can access our
2008 audited financial statements, MD&A
and other annual disclosures in the Investor Relations section of our website, www.thomsonreuters.com, as well as in our filings with securities regulatory authorities.

We believe that pro forma financial information provides more meaningful period-to-period comparisons of our 2008 performance because Reuters results prior to the April 17, 2008 acquisition closing date are not included in our Canadian GAAP results. Our pro forma results have been prepared as if the acquisition had closed on January 1, 2007. Pro forma financial information is for informational purposes only and is unaudited. For more information regarding how we prepare pro forma financial information, please see our MD&A.

We also use certain non-GAAP financial measures, such as revenue and operating profit from ongoing businesses, free cash flow and underlying free cash flow. Non-GAAP financial measures are defined and reconciled to the most directly comparable Canadian GAAP measures in our MD&A. We use these non-GAAP financial measures as supplemental indicators of our operating performance and financial position. These measures do not have any standardized meanings prescribed by Canadian GAAP and therefore are unlikely to be comparable to the calculation of similar measures used by other companies, and should not be viewed as alternatives to measures of financial performance calculated in accordance with Canadian GAAP.
