The share count for diluted earnings per share is computed on the basis of the weighted-average number of common shares outstanding plus the effects of dilutive common stock equivalents (CSEs) outstanding during the period. We excluded 0.1 million, 1.7 million and 0.4 million CSEs from the calculations of diluted earnings per share for the years 2017, 2016 and 2015 as the effect of including them would have been anti-dilutive.
