3. Earnings (Loss) Per Common Share

Basic earnings (loss) per common share are calculated by dividing net income (loss) 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. Due to a net loss applicable to common stockholders for the year ended December 31, 2013, we excluded 1,232,880 potentially dilutive securities from the computation as their effect would be anti-dilutive.
