	Three Months Ended					Nine Months Ended
	October 1, 2011			October 2, 2010		October 1, 2011			October 2, 2010
	(in thousands, except per share amounts)
Net income (loss)	$	(6,116	)	$	13,179	$	(15,766	)	$	26,946
Weighted-average shares — basic		22,951			22,383		22,843			22,288
Effect of dilutive potential common shares		—			504		—			643
Weighted-average shares — diluted		22,951			22,887		22,843			22,931
Net income (loss) per share — basic	$	0.27		$	0.59	$	0.69		$	1.21
Net income (loss) per share — diluted	$	0.27		$	0.58	$	0.69		$	1.18
Antidilutive shares based on employee awards excluded		3,024			2,293		1,589			1,668

Potentially dilutive common shares consist of shares issuable upon exercise of employee stock options, and are excluded from the calculation of diluted EPS when their effect would be anti-dilutive.
