For the six months ended June 30, 2018 and 2017, the Company’s income tax expense was $2,168 and $713, respectively. The increase in the income tax provision for the quarter and six months ended June 30, 2018 primarily related to a change in the geographical mix of income which increased taxable non-U.S. earnings before income taxes when compared to the prior year periods. This increase was partially offset by lower deferred tax expense in the 2018 periods related to the impact of the U.S. Tax Cuts and Jobs Act of 2017 to the amortization of tax goodwill. As of June 30, 2018 and December 31, 2017, the Company maintained a valuation allowance against its net deferred tax assets primarily attributable to operations in the United States, as the realization of such assets was not considered more likely than not.

The Company does not expect any significant changes to its unrecognized tax positions during the next twelve months. The Company recognizes interest and penalties related to uncertain tax positions in income tax expense.
