Income Tax Disclosure [Abstract]
Income Taxes	Income Taxes During the three and nine months ended September 30, 2017, we recorded consolidated income tax expense of $1.9 million and $10.9 million, respectively, with consolidated effective income tax rates of 6.1% and 9.3%, respectively. Our consolidated effective income tax rate for the three and nine months ended September 30, 2017 included the impact of various discrete tax items, including a net $4.0 million deferred tax benefit due to the release of valuation allowances on tax losses upon the completion of a reorganization of our legal entities in the U.S. and a $2.1 million tax benefit from the resolution of prior period tax matters. Discrete tax items for the nine months ended September 30, 2017 also included the acquisition of Caisson and the $38.1 million non-taxable gain recognized to re-measure our existing equity investment in Caisson at fair value on the acquisition date, a $3.9 million deferred tax benefit associated with certain temporary differences arising from the Mergers and the recognition of a $3.0 million deferred tax asset related to a reserve for an uncertain tax position recognized in a prior year, in addition to various other discrete items. During the three and nine months ended September 30, 2016, we recorded consolidated income tax expense of $9.7 million and $16.9 million, respectively, with consolidated effective income tax rates of 45.7% and 514.5%, respectively. The effective tax rate for the nine months ended September 30, 2016 was impacted by the recording of valuation allowances of $23.9 million related to certain tax jurisdictions, including France and the UK, in which we did not record tax benefits generated by their operating losses, as well as the tax expense generated by profitable operations in higher tax jurisdictions, such as the U.S. and Germany, offset by tax savings from our inter-company financing as part of our 2015 tax restructuring.
