Per Share Data

Basic and diluted net income per common share has been computed using the weighted average number of shares of common stock outstanding during the period, less shares subject to repurchase. The following table presents the calculation of basic and diluted net income per share (in thousands, except per share amounts):



	Three Months Ended				Nine Months Ended
	July 31,		July 31,		July 31,		July 31,
	2011		2010		2011		2010

Net income	$	474	$	130	$	398	$	733

Calculation of basic net income per share:
Weighted average - common shares outstanding	3,021		3,375		3,122		3,468
Net income per share, basic	$	0.16	$	0.04	$	0.13	$	0.21



	Three Months Ended				Nine Months Ended
	July 31,		July 31,		July 31,		July 31,
	2011		2010		2011		2010

Net income	$	474	$	130	$	398	$	733

Calculation of diluted net income per share:
Weighted average - common shares outstanding	3,021		3,375		3,122		3,468
Dilutive effect of employee and director stock options	—		28		1		36
Weighted average - common shares outstanding and potentially dilutive common shares	3,021		3,403		3,123		3,504
Net income per share, diluted	$	0.16	$	0.04	$	0.13	$	0.21

For the three months ended July 31, 2011 and 2010, 341,000 and 416,000 potentially dilutive shares, respectively, were excluded from the computation of diluted net income per share by the application of the treasury stock method. For the nine months ended July 31, 2011 and 2010, 355,000 and 347,000 potentially dilutive shares, respectively, were excluded from the computation of diluted net income per share by the application of the treasury stock method.
