Net Loss per Share

I. Net Loss per Share

We compute basic net loss per share by dividing net loss by the weighted average number of common shares outstanding during the relevant period. The components of basic and diluted net loss per share were as follows (in thousands, except per share data):

	Three Months Ended March 31,
	2013			2012
Net loss	$	(3,895	)	$	(12,416	)
Weighted average common shares outstanding	21,544			21,349
Net loss per share:
Basic and diluted	$	(0.18	)	$	(0.58	)

The following table sets forth the potential common shares issuable upon the exercise of outstanding options and the vesting of restricted stock units (prior to consideration of the treasury stock method), that were excluded from our computation of diluted net loss per share because such options and restricted stock units were anti-dilutive due to a net loss in the relevant periods (in thousands):

	Three Months Ended March 31,
	2013	2012
Options to purchase shares of common stock	2,750	1,717
Shares of common stock issuable upon the vesting of restricted stock units	510	679
