Note 3.  Basic and Diluted Net Loss Attributable to Common Stockholders per Common Share

The Company calculates net loss per share as a measurement of the Company’s performance while giving effect to all dilutive potential common shares that were outstanding during the reporting period.  The Company has a net loss for all periods presented; accordingly, the inclusion of common stock options and warrants would be anti-dilutive.  Therefore, the weighted average shares used to calculate both basic and diluted earnings per share are the same.

The following table provides a reconciliation of the numerator and denominator used in computing basic and diluted net loss attributable to common stockholders per common share:

Dilutive common stock equivalents would include the dilutive effect of common stock options and warrants for common stock equivalents.  Potentially dilutive common stock equivalents totaled approximately 9.2 million and 10.5 million for the three months ended March 31, 2012 and 2013, respectively.  Potentially dilutive common stock equivalents were excluded from the diluted earnings per share denominator for all periods because of their anti-dilutive effect.
