Earnings Per Share

Note 2 – Earnings Per Share

The weighted average number of shares outstanding used to compute earnings per common share were as follows (in millions):

	2015		2014		2013
Weighted average common shares outstanding for basic computations		310.3		316.8		320.9
Weighted average dilutive effect of equity awards		4.4		5.6		5.6
Weighted average common shares outstanding for diluted computations		314.7		322.4		326.5

We compute basic and diluted earnings per common share by dividing net earnings by the respective weighted average number of common shares outstanding for the periods presented. Our calculation of diluted earnings per common share also includes the dilutive effects for the assumed vesting of outstanding restricted stock units and exercise of outstanding stock options based on the treasury stock method.

The computation of diluted earnings per common share excluded 2.4 million stock options for the year ended December 31, 2013 because their inclusion would have been anti-dilutive, primarily due to their exercise prices exceeding the average market prices of our common stock during the respective periods. There were no anti-dilutive equity awards for the years ended December 31, 2015 and 2014.
