Earnings Per Share [Abstract]  
Earnings Per Share LOSS PER COMMON SHAREBasic 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. Although restricted stock is issued upon the grant of an award, the Company excludes restricted stock from the computations of weighted-average number of shares of common stock outstanding until such time as the stock vests. Diluted loss per share is computed by dividing the net income or loss by the sum of 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.
