Net Loss Per Share

15. Net Loss Per Share

Basic net loss per share amounts have been computed based on the weighted-average number of common shares outstanding. Diluted net loss per share amounts have been computed based on the weighted-average number of common shares outstanding plus the dilutive effect of potential common shares. The computation of potential common shares has been performed using the treasury stock method. Because of the net loss reported in each period, diluted and basic net loss per share amounts are the same.

The calculation of net loss and the number of shares used to compute basic and diluted earnings per share for the three-month periods ended March 31, 2013 and 2012 are as follows:

Weighted average shares outstanding – basic and diluted		178,541			160,970

For the three-month periods ended March 31, 2013 and 2012, the following potentially dilutive securities were not included in the computation of net loss per share because the effect would be anti-dilutive:
