Net Loss Per Share [Abstract]

Net Loss Per Share

8.   Net Loss per Share

Basic net loss per common share for the three and six months ended June 30, 2015 and 2014 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 43,000 and 0.3 million outstanding stock options and 0.2 million and 0.6 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 six months ended June 30, 2015 and 2014, respectively, due to their anti-dilutive effect.
