Computation of Net (Loss) Income per Common Share [Abstract]  
Computation of Net (Loss) Income Per Common Share

3. Computation of Net (Loss) Income per Common Share

     Basic net (loss) income per share ("EPS") is computed by dividing net (loss) income by the weighted-average number of common shares outstanding for the period. Where applicable, diluted EPS is computed by dividing the net (loss) income by the weighted-average number of common shares and dilutive common equivalent shares outstanding during the period, calculated using the treasury stock method. Common equivalent shares include the effect of restricted stock, exercise of stock options and warrants and contingently issuable shares. For the three months ended June 30, 2012, 6.3 million shares were not included in the calculation of diluted EPS as they were considered anti-dilutive, of which 3.1 million relate to unvested stock options and 3.2 million relate to the issuance of warrants. For the three months ended June 30, 2011, 3.0 million shares of unvested stock options were not included in the calculation of diluted EPS as they were considered anti-dilutive.

     The following table reconciles the numerators and denominators of the earnings per share calculation for the three months ended June 30, 2012 and 2011 (in thousands, except per share data):
