Earnings Per Share

9 Months Ended

Sep. 30, 2015

Basic earnings per share (EPS) is computed on the basis of the weighted average number of shares of common stock outstanding during the period. Diluted EPS is computed on the basis of the weighted average number of shares of common stock plus the effect of dilutive potential common shares outstanding during the period using the treasury stock method. Dilutive potential common shares include outstanding stock options and unvested shares. Reconciliations of basic and diluted EPS are as follows:
