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				Nine Months Ended
	September 30,				September 30,
	2017		2016		2017		2016
Weighted average shares outstanding for basic net earnings per share		202.3		200.1		201.7		199.9
Effect of dilutive stock options and other equity awards		1.7		2.8		1.9		2.4
Weighted average shares outstanding for diluted net earnings per share		204.0		202.9		203.6		202.3

During the three and nine month periods ended September 30, 2017, an average of 0.9 million options and 0.8 million options, respectively, to purchase shares of common stock were not included in the computation of diluted earnings per share because the exercise prices of these options were greater than the average market price of our common stock. In the three and nine month periods ended September 30, 2016, an average of 0.1 million options and 0.5 million options, respectively, were not included for the same reason.
