Earnings per share

Basic earnings per common share is computed by dividing net earnings available to common stockholders by the weighted average number of common shares outstanding during each period. Diluted earnings per common share assumes the exercise of outstanding stock options and the vesting of RSUs using the treasury stock method when the effects of such assumptions are dilutive. A reconciliation of net earnings available to common stockholders and weighted-average common shares outstanding for purposes of calculating basic and diluted earnings per share is as follows:
