Income Taxes

The provision for income taxes was as follows:



	Three Months Ended March 31,
	2017			2016
Income tax provision	$	12,993		$	54,495
Effective tax rate	23.4		%	98.0		%

The effective tax rate for the three months ended March 31, 2017 is lower than the US Federal tax rate of 35 percent mainly due to the mix of lower foreign jurisdiction tax rates, the effect of federal, foreign and state tax credits and discrete adjustments.

As of March 31, 2017, the Company had approximately $53.5 million of unrecognized tax benefits, all of which would affect the Company’s effective tax rate if recognized. The Company anticipates approximately $40.2 million of its net unrecognized tax benefits will be recognized within 12 months as the result of settlements or effective settlements with various tax authorities, the closure of certain audits and the lapse of the applicable statute of limitations.
