Net Loss Per Share

(6) Net Loss Per Share

Basic net loss per share is computed by dividing the net loss applicable to holders of common stock for the period by the weighted average number of shares of common stock outstanding during the period. The calculation of diluted net loss per share gives effect to common stock equivalents; however, potential common equivalent shares are excluded if their effect is antidilutive. Potential common equivalent shares are composed of incremental shares of common equivalent shares issuable upon the exercise of stock options and warrants.

The following tables set forth potential common stock that is not included in the diluted net loss per share calculation because their effect would be anti-dilutive for the periods indicated (in thousands, except exercise price per share data):
