Earnings Per Share [Abstract]

Net Loss per Share

14. Net Loss per Share

Basic and diluted net loss per share is computed by dividing the net loss by the weighted-average number of common shares outstanding during the period. The computation of net loss per share for each period, including the number of weighted-average shares outstanding, is shown on the face of the condensed consolidated statements of operations.

We have excluded the impact of common stock equivalents relating to shares underlying outstanding stock options from the calculation of diluted net loss per common share because all such securities are antidilutive for all periods presented.

The following outstanding shares of common stock and potential common shares were excluded from the computation of diluted net loss per share of common stock for the periods presented because including them would have been antidilutive:
