Net Income Per Share

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 all dilutive common share equivalents, comprised of shares issuable under the Corporation’s share-based compensation plans, and the weighted-average shares outstanding during the reporting period.

Dilutive common share equivalents include the dilutive effect of in-the-money share-based awards, which are calculated based on the average share price for each period using the treasury stock method. Under the treasury stock method, the exercise price of share-based awards, the amount of compensation expense, if any, for future service that the Corporation has not yet recognized, and the amount of estimated tax benefits that would be recorded in additional paid-in capital when share-based awards are exercised, are assumed to be used to repurchase common stock in the current period.

The following table reconciles basic and diluted net income per share for the three months ended March 31, 2015 and 2014.

	Three Months Ended March 31,
	2015					2014

Diluted net income per share	$	16,172	38,000,074	$	0.43	$	13,620	36,260,624	$	0.38

Stock options to purchase 367,576 and 648,182 shares for the three months ended March 31, 2015 and 2014, respectively, were not included in the earnings per share calculation because the exercise price exceeded the average market price.
