3. Net Income per Common Share

Net income per common share - Omnicom Group Inc. is based on the weighted average number of common shares outstanding during the periods. Diluted net income per common share - Omnicom Group Inc. is based on the weighted average number of common shares outstanding, plus, if dilutive, common share equivalents that include outstanding stock options and restricted shares.

Net income per common share is calculated using the two-class method, which is an earnings allocation method for computing net income per common share when an entity's capital structure includes common stock and participating securities. The application of the two-class method is required because our unvested restricted stock awards receive non-forfeitable dividends at the same rate as our common stock and therefore are considered participating securities. Under the two-class method, basic and diluted net income per common share is reduced for a presumed hypothetical distribution of earnings to holders of our unvested restricted stock.

The computations of basic and diluted net income per common share - Omnicom Group Inc. for the three and six months ended June 30, 2011 and 2010 were (in millions, except per share amounts):
