For the three and six months ended June 30, 2019 and June 30, 2018, stock awards representing the right to purchase common stock of approximately 750,000 and 1.0 million shares and 742,000 and 926,000 shares, respectively, were not included in the computation of diluted earnings per share because their inclusion would have had an antidilutive effect.
