Earnings per share attributable to stockholders

10.    Earnings per share attributable to stockholders

Basic earnings per share (“EPS”) attributable to stockholders was calculated by dividing the net income attributable to stockholders by the weighted average (“WA”) number of common shares outstanding during the period. Diluted EPS attributable to stockholders was calculated by dividing the net income attributable to stockholders by the weighted average number of shares of common stock outstanding if the potentially dilutive securities had been issued. Potentially dilutive securities include unvested PSUs, unvested RSUs, and outstanding stock options. The dilutive effect of potentially dilutive securities is reflected in diluted EPS by application of the treasury stock method. Under the treasury stock method, an increase in the fair market value of the Company’s common stock can result in a greater dilutive effect from potentially dilutive securities.
