Net Income (Loss) Per Share [Abstract]

Net Income (Loss) Per Share

3. Net Income (Loss) Per Share

The Company calculates earnings per share (“EPS”) as required by Financial Accounting Standards Board (“FASB”) Accounting Standards Codification (“ASC”) Topic No. 260, Earnings Per Share. Basic EPS is calculated by dividing the net income available to common stockholders by the weighted average number of common shares outstanding for the period, excluding common stock equivalents. Diluted EPS is computed by dividing the net income available to common stockholders by the weighted average number of common shares outstanding for the period plus the weighted average number of dilutive common stock equivalents outstanding for the period determined using the treasury-stock method. For periods with a net loss, the dilutive common stock equivalents are excluded from the diluted EPS calculation. For purposes of this calculation, common stock subject to repurchase by the Company and options are considered to be common stock equivalents and are only included in the calculation of diluted earnings per share when their effect is dilutive.
