NET INCOME PER SHARE

2.NET INCOME PER SHARE

Net income per share is computed based on the weighted-average number of common shares outstanding during the periods presented.  Additionally, diluted earnings per share data gives effect to all potentially dilutive common shares that were outstanding during the periods presented. For the three-month periods ended September 30, 2015 and 2014, stock options of 1.6 million and 2.8 million, respectively, and for the nine-month periods ended September 30, 2015 and 2014, stock options of 1.6 million and 2.1 million, respectively, were excluded from the calculation of diluted earnings per share because they were anti-dilutive.
