Earnings Per Common Share

2. Earnings Per Common Share

Basic earnings per common share are calculated by dividing net income by the weighted average number of common shares outstanding during the period. Diluted earnings per common share adjust basic earnings per common share for the effects of potentially dilutive common shares. Potentially dilutive common shares include the dilutive effects of shares issuable under our equity compensation plans, including stock options and restricted stock, each using the treasury stock method.
