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 June 30, 2013 and 2012, other stock options totaling 0.1 million and 0.1 million, respectively, and for the six-month periods ended June 30, 2013 and 2012, other stock options totaling 0.2 million and 0.1 million, respectively, were excluded from the calculation of diluted earnings per share because they were anti-dilutive.
