Note 2— Net Loss per Share

Basic earnings or losses per share are computed by dividing net income (loss) attributable to common stockholders by the weighted average number of common shares outstanding.  Diluted earnings or loss per share is computed by dividing net income (loss) attributable to common stockholders by the weighted average number of common shares and common stock equivalents outstanding, calculated on the treasury stock method for options and warrants using the average market prices during the period.

As the Company incurred a net loss in all periods presented, all potentially dilutive securities were excluded from the computation of diluted loss per share since the effect of including them is anti-dilutive.

The following table summarizes the number of dilutive securities, which may dilute future earnings per share, outstanding for each of the periods presented, but not included in the calculation of diluted loss per share:
