Basic and Diluted Net Loss per Common Share

7. Basic and Diluted Net Loss per Common Share

Basic net loss per common share has been computed by dividing net loss by the weighted average number of shares outstanding during the period. Diluted net income per share, if applicable, has been computed by dividing diluted net income by the diluted number of shares outstanding during the period. Except where the result would be antidilutive to loss from continuing operations, diluted net loss per share has been computed assuming the exercise of stock options, as well as their related income tax effects. The following table sets forth the computation of basic and diluted net loss per common share:

Net loss per share:

Diluted	$	(1.52	)	$	(0.81	)	$	(2.69	)	$	(1.35	)

The Company’s potential dilutive securities, which include stock options, have been excluded from the computation of diluted net loss per share as the effect would be to reduce the net loss per share. Therefore, the weighted-average common stock outstanding used to calculate both basic and diluted net loss per share are the same. The following shares of potentially dilutive securities have been excluded from the computations of diluted weighted average shares outstanding as the effect of including such securities would be antidilutive (in thousands):
