Net Loss Per Share
4. Net Loss Per Share

Basic net loss per share is computed by dividing the net loss for the period by the weighted-average number of common shares outstanding during the period less unvested restricted stock. Common equivalent shares are not used in the calculation of net loss per share because the effect would be antidilutive.

Employee stock options to purchase 2.8 million and 2.9 million shares have not been included in the computation of diluted net loss per share for the three and six months ended January 28, 2012, respectively, because their effect would have been antidilutive. Employee stock options to purchase 2.4 million and 2.5 million shares have not been included in the computation of diluted net loss per share for the three and six months ended January 29, 2011, respectively, because their effect would have been antidilutive.
