EARNINGS (LOSS) PER COMMON SHARE
 
Basic earnings (loss) per common share is computed by dividing the net income or loss by the basic weighted-average number of shares of common stock outstanding during each period presented. Diluted earnings per share is computed by dividing the net income or loss by the total of the basic weighted-average number of shares of common stock outstanding plus the additional dilutive securities that could be exercised or converted into common shares during each period presented less the amount of shares that could be repurchased using the proceeds from the exercises.
