Non-IFRS Financial Information

Readers are cautioned that the supplemental non-IFRS information presented in this press release is subject to inherent limitations. It is not based on any comprehensive set of accounting rules or principles and should not be considered as a substitute for IFRS measurements. Also, the Company’s supplemental non-IFRS financial information may not be comparable to similarly titled non-IFRS measures used by other companies. Further specific limitations for individual non-IFRS measures, and the reasons for presenting non-IFRS financial information, are set forth in the Company’s annual report for the year ended December 31, 2011 included in the Company’s 2011 Document de référence and the 2012 Half Year Financial Report filed with the AMF on March 29, 2012, and July 27, 2012, respectively.

In the tables accompanying this press release the Company sets forth its supplemental non-IFRS figures for revenue, operating income, operating margin, net income and diluted earnings per share, which exclude the effect of adjusting the carrying value of acquired companies’ deferred revenue, stock-based compensation expense and related social charges, the expenses for the amortization of acquired intangible assets, other income and expense, net, certain one-time items included in financial revenue and other, net, and the income tax effect of the non-IFRS adjustments. The tables also set forth the most comparable IFRS financial measure and reconciliations of this information with non-IFRS information.

Information in Constant Currencies

When the Company believes it would be helpful for understanding trends in its business, the Company provides percentage increases or decreases in its revenue (in both IFRS as well as non-IFRS) to eliminate the effect of changes in currency values, particularly the U.S. dollar and the Japanese yen, relative to the euro. When trend information is expressed herein "in constant currencies", the results of the "prior" period have first been recalculated using the average exchange rates of the comparable period in the current year, and then compared with the results of the comparable period in the current year.

This press release constitutes the quarterly financial information required by article L.451-1-2 IV of the French Monetary and Financial Code (Code Monétaire et Financier).
