Earnings Per Share

15.  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,
	2019		2018		2019		2018
Weighted average shares outstanding for basic net earnings per share		204.8		203.3		204.6		203.2
Effect of dilutive stock options and other equity awards		1.4		1.3		1.4		1.4
Weighted average shares outstanding for diluted net earnings per share		206.2		204.6		206.0		204.6

During the three and six month periods ended June 30, 2019, an average of 2.1 million options and 1.7 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 three and six month periods ended June 30, 2018, an average of 3.4 million options and 2.3 million options, respectively, were not included for the same reason.
