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,
	2016		2015
Numerator:
Net income	$	17,563	$	33,786

Denominator:
Shares used in net income per common share – basic		53,235,000		53,214,000
Effect of dilutive securities:
Stock options, restricted stock and employee stock purchase plan		328,000		315,000

Shares used in net income per common share – diluted		53,563,000		53,529,000

Net income per common share:
Basic	$	0.33	$	0.63
Diluted	$	0.33	$	0.63

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 (stock options and restricted stock units) had been converted to such common shares, and if such assumed conversion is dilutive.

As of March 31, 2016, restricted stock units related to an aggregate of approximately 737,000 shares were outstanding. For the three months ended March 31, 2016 and 2015, there were no weighted-average restricted stock units that would have an anti-dilutive effect on EPS, and would thus need to be excluded from the computation of diluted weighted-average shares.
