Earnings Per Share [Abstract]

Earnings Per Share

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

	Three Months Ended								Nine Months Ended
	September 30,								September 30,
	2012				2011				2012				2011
Net loss	$	(400	)		$	(1,083	)		$	(2,137	)		$	(4,609	)
Shares used in computing net loss per share - basic and diluted	18,338				17,905				18,202				15,787
Net loss per common share - basic and diluted	$	(0.02	)		$	(0.06	)		$	(0.12	)		$	(0.29	)

The increase in shares from the first nine months of 2011 compared to the first nine months of 2012 is primarily due to the sale of approximately 4,198 shares of common stock in an underwritten registered offering during May 2011.

Antidilutive Securities Excluded from Computation of Earnings Per Share

The following weighted average shares were excluded from the calculation of diluted net loss per share as their effect would have been anti-dilutive:

	Three Months Ended						Nine Months Ended
	September 30,						September 30,
	2012			2011			2012			2011
Employee equity incentive plans	4,178			3,798			4,038			3,715

Tabular disclosure of securities (including those issuable pursuant to contingent stock agreements) that could potentially dilute basic earnings per share (EPS) in the future that were not included in the computation of diluted EPS because to do so would increase EPS amounts or decrease loss per share amounts for the period presented, by antidilutive securities.
