Income Taxes	9 Months Ended

Income Tax Disclosure [Abstract]
Income Taxes	4. INCOME TAXES Our effective tax rate decreased from an expense of 23.1% in the nine months ended September 30, 2017, to a benefit of 34.9%, excluding the tax effect of the bargain purchase gain, in the nine months ended September 30, 2018. The decrease in the effective tax rate between the two periods is primarily driven by the completion of other tax projects, current year net losses in our domestic business and the effect of the U.S. Tax Cuts and Jobs Act, which was signed into law on December 22, 2017.
