Basic earnings (loss) per share is computed based on the weighted-average number of shares of common stock outstanding during the period. Diluted earnings (loss) per share is computed based on the weighted-average number of shares of common stock outstanding during the period plus additional shares of common stock that would have been outstanding if potentially dilutive securities had been issued. Potentially dilutive shares of common stock include outstanding stock options, restricted stock units, contingently issuable shares, and shares to be purchased under our employee stock purchase plan.
