Earnings Per Share [Abstract] |
Net Loss Per Share | 10. Net Loss Per Share Basic net loss per common share for the three and six months ended June 30, 2012 and 2011 was computed by dividing the net loss for the relevant period by the weighted average number of shares of common stock outstanding. Diluted earnings per common share is computed by dividing net loss attributable to common stockholders by the weighted average number of shares of common stock and common stock equivalents outstanding. Potential common stock equivalents of 103,000 and zero stock options outstanding under the treasury stock method, 3.4 million and 5.4 million outstanding stock warrants under the treasury stock method, 52,000 and 55,000 shares issuable upon conversion of preferred stock and zero and 1.7 million shares issuable upon conversion of notes are excluded from the diluted earnings per share calculation for the six months ended June 30, 2012 and 2011, respectively, due to their anti-dilutive effect.
