Earnings Per Share [Abstract]

Net Income (Loss) Per Share

Net Income (Loss) Per Share

The Company computes basic net income (loss) per share using the weighted-average number of common shares outstanding during the period. Diluted net income (loss) per share assumes the conversion, exercise or issuance of all potential common stock equivalents, unless the effect of inclusion would be anti-dilutive. For purposes of this calculation, common stock equivalents include the Company’s stock options, employee stock purchase plan shares, restricted stock units, including those with performance conditions, warrants, and shares to be issued upon the conversion of the Senior Convertible Notes (see Note 6, Senior Convertible Notes).

The following table sets forth the computation of basic and diluted earnings or (loss) per share attributable to the Company (in thousands, except per share data):
