14)	Net Income Per Share

The following table sets forth the computation of basic and diluted net income per share:


	Three Months Ended March 31,
	2019		2018
Numerator:
Net income	$	12,455	$	105,121

Denominator:
Shares used in net income per common share – basic		54,147,000		54,423,000
Effect of dilutive securities:
Restricted stock units, stock appreciation rights and shares issued under employee stock purchase plan		701,000		863,000

Shares used in net income per common share – diluted		54,848,000		55,286,000

Net income per common share:
Basic	$	0.23	$	1.93
Diluted	$	0.23	$	1.90

Basic earnings per share (“EPS”) is computed by dividing income available to common stockholders by the weighted-average number of common shares outstanding during the period. The computation of diluted EPS is similar to the computation of basic EPS except that the denominator is increased to include the number of additional common shares that would have been outstanding (using the treasury stock method) if securities containing potentially dilutive common shares (restricted stock units and stock appreciation rights) had been converted to such common shares, and if such assumed conversion is dilutive.

For the three months ended March 31, 2019 and 2018 there were approximately 128,200 and 380 weighted-average restricted stock units, respectively, that would have had an anti-dilutive effect on EPS, and would thus need to be excluded from the computation of diluted weighted-average shares.
