Income Tax Disclosure [Abstract]
Income Tax Expense	13. INCOME TAX EXPENSE The effective tax rates for the three months ended June 30, 2019 and 2018 were 19.8% and 16.6%, respectively, and for the six months ended June 30, 2019 and 2018 were (61.7)% and 17.3%, respectively. The income tax expense of $4.8 million in the second quarter of 2019 decreased by $0.2 million compared to $5 million in the same period in 2018, due to the result of several items discrete to each quarter, along with changes in activity levels in jurisdictions with differing tax rates. Tax expense included a net tax benefit of $58.5 million which resulted from a corporate restructuring in the first quarter and tax expense of $26.7 million related to unremitted earnings of foreign subsidiaries that we no longer consider to be indefinitely reinvested, each of which was a discrete item in the first quarter of 2019.

The entire disclosure for income taxes. Disclosures may include net deferred tax liability or asset recognized in an enterprise's statement of financial position, net change during the year in the total valuation allowance, approximate tax effect of each type of temporary difference and carryforward that gives rise to a significant portion of deferred tax liabilities and deferred tax assets, utilization of a tax carryback, and tax uncertainties information.
