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

(in thousands, except per share data)	Three months ended July 31,				Six months ended July 31,
	2019		2018		2019		2018
Numerator (basic and diluted):
Net income	$	19,366	$	22,517	$	61,188	$	45,094
Denominator (basic):
Weighted-average common shares outstanding	64,220		61,880		63,289		61,531
Denominator (diluted):
Weighted-average common shares outstanding	64,220		61,880		63,289		61,531
Weighted-average dilutive effect of stock options and restricted stock units	1,363		1,517		1,496		1,529
Diluted weighted-average common shares outstanding	65,583		63,397		64,785		63,060
Net income per share:
Basic	$	0.30	$	0.36	$	0.97	$	0.73
Diluted	$	0.30	$	0.36	$	0.94	$	0.72

For the three months ended July 31, 2019 and 2018, approximately 0.3 million and 0.1 million shares, respectively, attributable to stock options and restricted stock units were excluded from the calculation of diluted earnings per share as their inclusion would have been anti-dilutive.

For the six months ended July 31, 2019 and 2018, approximately 0.3 million and 0.1 million shares, respectively, attributable to stock options, restricted stock units were excluded from the calculation of diluted earnings per share as their inclusion would have been anti-dilutive.
