Net income per share

2. Net income per share

Basic net income per share is calculated by dividing net income by the weighted-average number of common shares outstanding for the period. Diluted net income per share is computed by dividing net income by the weighted-average number of common shares outstanding for the period, including potential dilutive common shares assuming the dilutive effect of outstanding stock options using the treasury-stock method.

The following table presents the calculation of basic and diluted net income per share (in thousands, except per share amounts):

	Three Months Ended March 31,				Nine Months Ended March 31,
	2012		2011		2012		2011
Net income	$	7,351	$	11,165	$	25,778	$	33,563
Shares used in computing net income per share:
Basic:
Weighted average common shares used in computing basic net income per share		41,454		41,919		41,412		42,063
Diluted:
Weighted average common shares used in computing basic net income per share		41,454		41,919		41,412		42,063
Add weighted average effect of dilutive securities:
Stock options		2,125		3,262		2,796		2,873
Weighted average common shares used in computing diluted net income per share		43,579		45,181		44,208		44,936
Net income per share:
Basic	$	0.18	$	0.27	$	0.62	$	0.80
Diluted	$	0.17	$	0.25	$	0.58	$	0.75

The following outstanding shares subject to options were excluded from the computation of diluted net income per share for the periods presented because including them would have had an antidilutive effect (in thousands):

	Three Months Ended March 31,				Nine Months Ended March 31,
	2012		2011		2012		2011
Options to purchase common stock		2,117		1,159		1,235		1,236
