There were no antidilutive shares for the three months ended June 30, 2018. Diluted earnings per share for the three months ended June 30, 2017 excluded the effect of 0.3 million shares of common stock (0.1 and 0.3 million for the six months ended June 30, 2018 and 2017, respectively), that may be issued upon the exercise of employee stock options, because such effect would be antidilutive.
