Income Taxes

Note 12. Income Taxes

The following table summarizes the Company's income tax provision and effective income tax rate:

	Three Months Ended March 31,
	2012			2011
Income before income taxes	$	77,181		$	82,438
Provision for income taxes	$	22,066		$	22,539
Effective income tax rate		28.6	%		27.3	%

The year over year increase in the effective tax rate is primarily attributable to the lapse of the statute of limitations in a non-U.S. jurisdiction related to an uncertain tax position in the first quarter of 2011 and a higher percentage of U.S. profits in the first quarter of 2012 compared to the first quarter of 2011, which are generally taxed at a higher rate than the Company's foreign earnings.
