NET INCOME PER SHARE

Basic net income per share is computed by dividing net income by the weighted-average shares outstanding during the reporting period. Diluted net income per share is computed by dividing net income by the combination of the weighted-average shares outstanding during the reporting period and all potentially dilutive common shares. Potentially dilutive common shares include stock options and RSAs issued under the Corporation's share-based compensation plans. Potentially dilutive common shares are excluded from the computation of diluted earnings per share in the periods where the effect would be antidilutive.

The following table reconciles basic and diluted net income per share for the three and nine months ended September 30, 2017 and 2016.

For the three months ended September 30, 2017, there were no stock options with an option price greater than the average market price of the common shares. Stock options to purchase 53,550 shares for the three months ended September 30, 2016 were excluded from the computation of diluted net income per share because the exercise price for the options was greater than the average market price of the common shares and, therefore, the effect would be antidilutive.

For the nine months ended September 30, 2017, there were no stock options with an option price greater than the average market price of the common shares. Stock options to purchase 119,157 shares for the nine months ended September 30, 2016 were excluded from the computation of diluted net income per share because the exercise price for the options was greater than the average market price of the common shares and, therefore, the effect would be antidilutive.
