Net Loss per Share

Note 11. Net Loss Per Share

Basic loss per common share is computed by dividing net loss by the weighted average number of common shares outstanding during the reporting period. Diluted loss per common share is computed similar to basic loss percommon share except that it reflects the potential dilution that could occur if dilutive securities or other obligations to issue common stock were exercised or converted into common stock.

The following table provides the numerator and denominator used in computing basic and diluted net loss per share for the periods indicated:

Net loss per share, basic and diluted	$	(0.19	)	$	(0.22	)

The following outstanding securities were excluded from the computation of diluted net loss per share for the periods presented because their effect would have been anti-dilutive:
