Basic earnings per common share is calculated by dividing net income by the weighted average number of common shares outstanding during the period. Diluted earnings per common share adjusts basic earnings per common share for the effects of potentially dilutive common shares. Potentially dilutive common shares include the dilutive effects of shares issuable upon exercise or vesting of outstanding awards under our equity compensation plans, including stock options and share-based awards (restricted share awards, restricted stock units and performance stock units), each using the treasury stock method.
