Net Loss Per Common Share

6. NET LOSS PER COMMON SHARE

Basic net loss per common share excludes dilution for potentially dilutive securities and is computed by dividing loss attributable to common stockholders by the weighted average number of common shares outstanding during the period. Diluted net loss per common share gives effect to dilutive options, warrants and other potential common shares outstanding during the period. Diluted net loss per common share is equal to the basic net loss per common share since all potentially dilutive securities are anti-dilutive for each of the periods presented. Potential common stock equivalents outstanding as of March 31, 2014 and March 31, 2013 consist of common stock equivalents of convertible preferred stock, stock options, common stock purchase warrants and restricted stock, which are summarized as follows:
