Earnings Per Share [Abstract]

Earnings Per Share

12. Earnings Per Share

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

	Three Months Ended September 30,				Nine Months Ended September 30,
	2014		2013		2014		2013
Weighted average shares outstanding for basic net earnings per share		169.0		170.0		168.8		169.2
Effect of dilutive stock options and other equity awards		2.7		2.2		2.7		2.0
Weighted average shares outstanding for diluted net earnings per share		171.7		172.2		171.5		171.2

During the three and nine month periods ended September 30, 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. During the three and nine month periods ended September 30, 2013, an average of 1.4 million options and 4.2 million options, respectively, had exercise prices that were greater than the average market price of our common stock and were not included in the computation.
