Earnings Per Share [Abstract]

Net Loss per Share

Net Loss per Share

Basic net loss per share is computed by dividing net loss by the weighted-average number of common shares outstanding for the period. Diluted net loss per share is computed giving effect to all potential dilutive common stock, including stock options, restricted stock units and common stock subject to repurchase. Diluted loss per share for the three and six months ended June 30, 2012 and June 25, 2011, respectively, was based only on the weighted-average number of shares outstanding during that period as the inclusion of any common stock equivalents would have been anti-dilutive.

A reconciliation of the numerator and denominator used in the calculation of basic and diluted net loss per share follows (in thousands):

	Three Months Ended						Six Months Ended
	June 30, 2012			June 25, 2011			June 30, 2012			June 25, 2011
Numerator:
Net loss used in computing basic and diluted net loss per share	$	(4,217	)	$	(7,678	)	$	(21,671	)	$	(29,102	)
Denominator:
Weighted-average shares used in computing basic net loss per share	49,817			50,773			49,652			50,705

Weighted average shares used in computing basic and diluted net loss per share	49,817			50,773			49,652			50,705

The following table sets forth the weighted-average number of all potentially dilutive securities excluded from the computation in the table above because their effect would have been anti-dilutive (in thousands):

	Three Months Ended		Six Months Ended
	June 30, 2012	June 25, 2011	June 30, 2012	June 25, 2011
Options to purchase common stock	4,464	4,834	4,538	4,846
Restricted stock units	1,304	1,210	1,258	1,080
