Net Income Per Share | Net Income Per Share The following table reconciles net income and shares used in the calculation of basic net income per share to those used for diluted net income per share:
For the three month period ended September 30, 2013, the number of shares from stock-based compensation plans not included in the computation of diluted net income per share, because their impact was antidilutive, was immaterial. During the nine months ended September 30, 2013, there were 0.7 million antidilutive shares excluded from the computation. There were 0.1 million and 2.9 million antidilutive shares outstanding during the three and nine month periods ended September 30, 2012, respectively. |
