Earnings Per Share [Abstract]

Earnings Per Share

13. Earnings Per Share

The following is a reconciliation of weighted average shares for the basic and diluted shares computations (in millions):

	Three Months Ended March 31,
	2015		2014
Weighted average shares outstanding for basic net earnings per share		170.0		169.1
Effect of dilutive stock options and other equity awards		2.9		2.7
Weighted average shares outstanding for diluted net earnings per share		172.9		171.8

During the three month periods ended March 31, 2015 and 2014, all outstanding options to purchase shares of common stock were included in the computation of diluted earnings per share because the exercise prices of all options were less than the average market price of our common stock.
