EARNINGS PER SHARE

3 Months Ended

Mar. 31, 2017

Basic earnings per share is computed by dividing income available to common shareholders by the weighted-average number of shares of common stock outstanding during the period. Diluted earnings per share is computed by dividing income available to common shareholders by the weighted-average number of shares of common stock outstanding during the period increased to include the number of additional shares of common stock that would have been outstanding if the potentially dilutive securities had been issued. Potentially dilutive securities include outstanding stock options, unvested restricted stock and unvested equity-settled RSUs. The dilutive effect of potentially dilutive securities is reflected in diluted earnings per share by application of the treasury stock method.

The following table sets forth the computation of basic and diluted earnings per share of common stock as follows:



	Three Months Ended March 31,
	2017		2016
Numerator for basic and diluted earnings per share:
Net income	$	23,641	$	23,899
Numerator for basic and diluted earnings per share	$	23,641	$	23,899

Denominator:
Weighted average common shares for basic earnings per share	50,958		49,714
Net effect of dilutive stock options, restricted stock units and restricted stock awards	2,931		3,169
Weighted average common shares for diluted earnings per share	53,889		52,883

Net income per share:
Basic	$	0.46	$	0.48
Diluted	$	0.44	$	0.45

The number of shares underlying equity-based awards excluded from the calculation of diluted earnings per share because the effect would be anti-dilutive, was 2,272 and 2,218 during the three months ended March 31, 2017 and 2016, respectively.
