14)	Net Income Per Share

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


	Three Months Ended June 30,				Six Months Ended June 30,
	2019		2018		2019		2018
Numerator:
Net income	$	37,739	$	122,862	$	50,194	$	227,983

Denominator:
Shares used in net income per common share – basic		54,815,000		54,719,000		54,481,000		54,571,000
Effect of dilutive securities:
Restricted stock units, stock appreciation rights and shares issued under employee stock purchase plan		274,000		555,000		485,000		709,000

Shares used in net income per common share – diluted		55,089,000		55,274,000		54,966,000		55,280,000

Net income per common share:
Basic	$	0.69	$	2.25	$	0.92	$	4.18
Diluted	$	0.69	$	2.22	$	0.91	$	4.12

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 (“RSUs”) and stock appreciation rights (“SARs”)) had been converted to such common shares, and if such assumed conversion is dilutive.

For the three and six months ended June 30, 2019, there were approximately 206,000 and 166,000 weighted-average RSUs, 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.

For the three and six months ended June 30, 2018, there were approximately 99,000 and 49,000 weighted-average RSUs, 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.
