In accordance with the presentation requirements of ASC Topic 810, we modified the format of our consolidated statement of income to conform to the disclosure requirements of the revised guidance.

(b)

On January 1, 2009, we adopted revisions to ASC Topic 260, Earnings per Share - Participating Securities and the Two-Class Method, which requires all outstanding unvested share-based payments that contain rights to non-forfeitable dividends participate in the undistributed earnings with the common shareholders and are therefore participating securities. Companies with participating securities are required to apply the two-class method in calculating basic and diluted earnings per share. On adoption of the revised guidance, we retrospectively restated basic and diluted Net Income per Common Share - Omnicom Group Inc. for each period presented. The adoption reduced Net Income, for the purposes of the basic and diluted net income per common share, for the three months ended December 31, 2009 and 2008, by $2.5 million and $3.9 million, respectively.
