Net Loss Attributable to Common Stockholders Per Share

Net Loss Attributable to Common Stockholders Per Share

Potentially issuable shares of common stock include shares issuable upon the exercise of outstanding employee stock option awards. Awards granted with performance conditions are excluded from the shares used to compute diluted earnings per share until the performance conditions associated with the awards are met.

The following table sets forth the computation of basic and diluted earnings per common share (in thousands, except share and per share data):

Net loss per share attributable to common stockholders, basic and diluted	$	(0.27)	$	(4.25)	$	(0.51)	$	(7.29)

Since the Company was in a loss position for all periods presented, basic net loss per share attributable to common stockholders is the same as diluted net loss per share attributable to common stockholders, as the inclusion of all potential shares of common stock outstanding would have been anti-dilutive. The following weighted-average common stock equivalents were excluded from the calculation of diluted net loss per share attributable to common stockholders for the periods presented as they had an anti-dilutive effect:
