Net Loss per Share

Note 12. Net Loss Per Share

Basic loss per common share is computed by dividing net loss allocable to common stockholders by the weighted average number of shares of common stock or common stock equivalents outstanding. Diluted loss per common share is computed similar to basic loss per common share except that it reflects the potential dilution that could occur if dilutive securities or other obligations to issue common stock were exercised or converted into common stock.

The following common stock equivalents were excluded from the computation of diluted net loss per share for the periods presented because their effect would have been anti-dilutive:
