Per Share Data

Basic and diluted net income (loss) 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 (loss) per share (in thousands, except per share amounts):



	Three Months Ended					Nine Months Ended
	July 31, 2012			July 31, 2011		July 31, 2012			July 31, 2011

Net income (loss)	$	(1,169	)	$	474	$	(1,247	)	$	398

Calculation of basic net income (loss) per share:
Weighted average - common shares outstanding	2,755			3,021		2,839			3,122
Net income (loss) per share, basic	$	(0.42	)	$	0.16	$	(0.44	)	$	0.13

Calculation of diluted net income (loss) per share:
Weighted average - common shares outstanding	2,755			3,021		2,839			3,122
Dilutive effect of employee and director stock options	—			—		—			1
Weighted average - common shares outstanding and potentially dilutive common shares	2,755			3,021		2,839			3,123
Net income (loss) per share, diluted	$	(0.42	)	$	0.16	$	(0.44	)	$	0.13

For the three months ended July 31, 2012 and 2011, 644,000 and 341,000 potentially dilutive shares, respectively, were excluded from the computation of diluted net income (loss) per share by the application of the treasury stock method. For the nine months ended July 31, 2012 and 2011, 643,000 and 355,000 potentially dilutive shares, respectively, were excluded from the computation of diluted net income (loss) per share by the application of the treasury stock method.
