Dilutive potential common shares, using treasury stock method		1,266		1,079		—
Weighted average shares outstanding—diluted		38,673		37,726		36,175

Basic	$	2.13	$	1.12	$	(0.48	)
Diluted	$	2.06	$	1.09	$	(0.48	)

For 2011, 2010 and 2009, 1,098,960, 1,198,164 and 2,432,931 stock options and/or stock appreciation rights with weighted-average exercise prices and/or base values of $15.64, $15.72 and $20.95, respectively, were excluded from the computations of diluted net income (loss) per share, as their inclusion would be antidilutive. In addition, for 2010 and 2009, 372,091 and 1,236,920 restricted stock units representing shares that were issuable contingent upon the achievement of performance conditions were excluded from the computation of diluted net income (loss) per share, as the performance criteria had not been met. For 2009, an additional 749,524 common stock equivalents have been excluded from the denominator for purposes of computing diluted net loss per share, as their inclusion would be antidilutive due to the Company incurring a net loss.

For 2011, 2010 and 2009, the Company's convertible subordinated notes had no impact on diluted net income (loss) per share as the average price of the Company's common stock during those periods was below $24.05, and the convertible subordinated notes, if converted, would require only cash settlement.
