Net Loss per Share [Abstract]

Net Loss per Share

Note 3. Net Loss per Share

Basic net loss per share has been computed using the weighted-average number of common shares outstanding during the period. Dilutive net loss per share is computed using the sum of the weighted average number of common shares outstanding and the potential number of dilutive common shares outstanding during the period. Potential common shares consist of the shares issuable upon exercise of stock options and warrants. Potentially dilutive securities have been excluded from the computation of diluted net loss per share in 2012 and 2011 as their inclusion would be antidilutive. For the three and six months ended June 30, 2012, 27,775,339 options and warrants were excluded from the calculation of diluted net loss per share because the effect was anti-dilutive. For the three and six months ended June 30, 2011, 11,510,978 options and warrants were excluded from the calculation of diluted net loss per share because the effect was anti-dilutive.

The following table sets forth the computation of basic and diluted net loss per share:
