Income Taxes

The provision for income taxes was as follows:



	Three Months Ended March 31,
	2016			2015
Income tax provision	$	54,495		$	15,130
Effective tax rate	98.0		%	24.0		%

The effective tax rate for the three months ended March 31, 2016 is higher than the US Federal tax rate of 35 percent primarily due to discrete tax charges, partially offset by the mix of lower foreign jurisdiction tax rates and the effect of federal, foreign and state tax credits. During the first quarter of 2016, the Company recorded discrete tax expenses of $40.0 million primarily related to the European Commission’s decision regarding certain tax legislation in Belgium impacting one of the Company’s international subsidiaries. The Belgian Government announced that they have appealed this decision and filed an action for annulment with the General Court of the European Union. Companies directly affected by the decision may also appeal. The outcome of an appeal, new information received from the Belgian Government, or other future events may cause the income tax provision associated with the decision to be entirely or partially reversed.

As of March 31, 2016, the Company had approximately $53.8 million of unrecognized tax benefits, all of which would affect the Company’s effective tax rate if recognized. The Company anticipates an immaterial portion 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.

The Company classifies interest and penalties related to uncertain tax positions as income tax expense. As of March 31, 2016, the Company had approximately $1.9 million of net accrued interest and penalties related to uncertain tax positions.

The Company currently has the following tax years open to examination by major taxing jurisdictions:
