Denominator for basic earnings per share-weighted-average shares outstanding		60,328			59,211			60,056			59,049
Dilutive effect of stock options and restricted stock units		202			294			281			307
Denominator for diluted earnings per share		60,530			59,505			60,337			59,356
Per share income
Basic	$	0.26		$	0.33		$	0.85		$	0.79
Diluted		0.26			0.33			0.85			0.79
______________________
(1) Basic weighted-average shares outstanding		60,328			59,211			60,056			59,049
Basic weighted-average shares outstanding and
unvested restricted share units expected to vest		60,371			59,423			60,171			59,346
Percentage allocated to shareholders		99.9	%		99.6	%		99.8	%		99.5	%

      The calculation of earnings per share shown above excludes the income attributable to the company's unvested restricted stock units that include rights to receive non-forfeitable dividends from the numerator and excludes the impact of those units from the denominator.  Diluted weighted-average shares for all periods also exclude the effect of the company's convertible notes that were anti-dilutive.
