Loss Per Share

(2) Loss Per Share

The Company calculates basic earnings per share by dividing loss attributable to common stockholders by the weighted average common shares outstanding during the period, excluding common stock subject to vesting provisions. Diluted earnings per share is computed by dividing loss attributable to common stockholders by the weighted average number of common shares outstanding during the period increased to include, if dilutive, the number of additional common shares that would have been outstanding if the potential common shares had been issued. The Company’s potentially dilutive shares include options and warrants.

A reconciliation of the numerator and denominator used in the calculation of basic and diluted loss per share follows:

Potentially dilutive securities representing 4.8 million and 2.4 million weighted average shares of common stock were excluded for the three months ended September 30, 2012 and 2011, respectively, and potentially dilutive securities representing 4.0 million and 2.0 million weighted average shares of common stock were excluded for the nine months ending September 30, 2012 and 2011, respectively, because including them would have an anti-dilutive effect on net loss per share.
