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				Six Months Ended
	June 30,				June 30,
	2017		2016		2017		2016
Weighted average shares outstanding for basic net earnings per share		201.8		199.4		201.4		199.8
Effect of dilutive stock options and other equity awards		1.9		-		2.0		2.3
Weighted average shares outstanding for diluted net earnings per share		203.7		199.4		203.4		202.1

During the three and six month periods ended June 30, 2017, an average of 1.0 million and 0.7 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 six month period ended June 30, 2016, an average of 0.7 million options were not included for the same reason. Since we incurred a net loss in the three month period ended June 30, 2016, no dilutive stock options or other equity awards were included as diluted shares.
