Earnings Per Share [Abstract]  
Earnings (Loss) Per Share
Earnings (Loss) Per Share
Basic (loss) earnings per share is computed by dividing net (loss) income available to common stockholders by the weighted-average number of common shares outstanding. Diluted (loss) earnings per share is computed by dividing net (loss) income available to common stockholders by the weighted-average number of common shares plus the effect of dilutive potential common shares outstanding during the period. Diluted (loss) earnings per share for the three months ended June 30, 2012 and 2011 excludes the impact of approximately 13.5 million and 2.1 million common stock equivalents, respectively, since the effect of including these securities would be anti-dilutive. Diluted (loss) earnings per share for the six months ended June 30, 2012 and 2011 excludes the impact of approximately 14.0 million and 3.6 million common stock equivalents, respectively, since the effect of including these securities would be anti-dilutive. The following table sets forth the computation of basic and diluted (loss) earnings per share (shares in thousands):
