5. BASIC AND DILUTED NET LOSS PER SHARE

 

Basic net loss per share is computed by dividing net loss by the weighted-average number of common shares outstanding, excluding the dilutive effects of common stock equivalents. Common stock equivalents include stock options and warrants. Diluted net loss per share is computed by dividing net loss by the weighted-average number of dilutive common shares outstanding during the period. Diluted shares outstanding is calculated by adding to the weighted shares outstanding any potential (unissued) shares of common stock from outstanding stock options and warrants based on the treasury stock method. In periods when a net loss is reported, all common stock equivalents are excluded from the calculation because they would have an anti-dilutive effect, meaning the loss per share would be reduced. Therefore, in periods when a loss is reported there is no difference in basic and dilutive loss per share.

 

The number of shares of potentially dilutive common stock related to options and warrants that were excluded from the calculation of dilutive shares since the inclusion of such shares would be anti-dilutive for the three and nine months ended September 30, 2011 and 2010, respectively, are shown below:
