NET INCOME PER SHARE

NET INCOME PER SHARE

NOTE 3.  NET INCOME PER SHARE

Basic net (loss) income per share is calculated by dividing the net (loss) income by the weighted-average number of shares of common stock outstanding during the period. Diluted net (loss) income per share is calculated by dividing the net (loss) income by the weighted-average number of shares of common stock outstanding during the period, plus potentially dilutive common shares, consisting of unexercised stock options, unvested restricted stock awards, outstanding shares under the employee stock purchase plan and convertible notes. The Company uses the treasury-stock method to compute diluted earnings per share with respect to its stock options and equivalents. The Company uses the if-converted method to compute diluted earnings per share with respect to its convertible notes. For purposes of this calculation, options to purchase stock are considered to be potential common shares and are only included in the calculation of diluted net (loss) income per share when their effect is dilutive. Basic and diluted earnings per common share are calculated as follows:

The following table sets forth outstanding potentially dilutive common shares that are not included in the computation of diluted net (loss) income per share because, to do so would be anti-dilutive:
