Net loss per share

3. Net loss per share

Basic net loss per share is computed by dividing the net loss for the period attributable to common stockholders by the weighted average number of shares of common stock outstanding during the period. Diluted net loss per share takes into consideration shares of common stock outstanding (computed under basic loss per share) and potentially dilutive shares of common stock. Diluted net loss per share is not presented separately from basic net loss per share as the conversion of outstanding stock options and warrants into common shares would be anti-dilutive. At June 30, 2012 and 2011, the total number of potentially dilutive shares of common stock of the Company excluded from basic net loss per share was 4,343,334 and 1,910,001, respectively.
