		Net income	$	19,452		$	16,473		$	47,059		$	50,024

		Numerator for basic and diluted earnings per share	$	19,374		$	16,341		$	46,824		$	49,524
Denominator
		Denominator for basic earnings per share -
		weighted-average shares outstanding		59,211			58,598			59,049			58,441
		Dilutive effect of stock options and restricted stock units		294			389			307			544
		Denominator for diluted earnings per share		59,505			58,987			59,356			58,985
Per share income
		Basic	$	0.33		$	0.28		$	0.79		$	0.85
		Diluted		0.33			0.28			0.79			0.84
_________________________
	(1)	Basic weighted-average shares outstanding		59,211			58,598			59,049			58,441
		Basic weighted-average shares outstanding and
		unvested restricted share units expected to vest		59,423			59,062			59,346			59,047
		Percentage allocated to shareholders		99.6	%		99.2	%		99.5	%		99.0	%

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.
