Net Loss Per Share [Abstract] |
Net Loss Per Share | 8. Net Loss Per Share Basic net loss per common share for the three and nine months ended September 30, 2014 and 2013 was computed by dividing the net loss for the relevant period by the weighted average number of shares of common stock outstanding. Diluted loss per common share is computed by dividing net loss by the weighted average number of shares of common stock and common stock equivalents outstanding. Potential common stock equivalents of approximately 0.1 million and 0.4 million outstanding stock options, 0.4 million and 0.5 million outstanding stock warrants under the treasury stock method and 11,000 and 11,000 shares issuable upon conversion of preferred stock are excluded from the diluted earnings per share calculation for the nine months ended September 30, 2014 and 2013, respectively, due to their anti-dilutive effect.
