Net Loss per Share [Abstract]

Net Loss per Share

(4) Net Loss per Share

Basic net loss per share is computed on the basis of the weighted average number of shares of common stock outstanding during the period. Diluted net loss per share is computed on the basis of the weighted average number of shares of common stock plus the effect of dilutive potential common shares outstanding during the period using the treasury stock method and the if-converted method. Dilutive potential common shares include outstanding stock options, convertible debt, and shared-based awards. Reconciliation and the components of basic and diluted net loss per share are as follows (in thousands, except per share data):
