Income Tax

The Company estimates its annual effective income tax rate at the end of each quarterly period. The estimate takes into account the geographic mix of expected pre-tax income (loss), expected total annual pre-tax income (loss), enacted changes in tax laws, implementation of tax planning strategies and possible outcomes of audits and other uncertain tax positions. To the extent there are fluctuations in any of these variables during a period, the provision for income taxes may vary.

The provision for income taxes for the first quarter of 2017 and 2016 was $10.0 million (18.2% of income before taxes) and $21.0 million (43.6% of income before taxes), respectively. The decrease in income tax expense in 2017 was primarily attributable to a tax benefit resulting from the restructuring of certain foreign entities.
