Income tax provision	$	132		$	111
Effective tax rate	25.0		%	23.4		%

Our effective tax rate was lower than the U.S. federal statutory rate of 35% primarily due to the majority of our income being earned outside the U.S. where tax rates are generally lower than the U.S. rate.

Our first quarter effective tax rate was higher than the prior year primarily due to the increased cost of repatriating current year foreign earnings.
