Income Tax Disclosure [Abstract]  
Income Tax Disclosure [Text Block] Income TaxFor the three months ended March 31, 2021, the Company recorded income tax expense of $47 million on pre-tax income of $186 million, or an effective tax rate of 25.3%. The increase to the effective tax rate over the U.S. statutory income tax rate of 21% was primarily the result of income earned in jurisdictions with tax rates higher than the U.S., global intangible low-taxed income (“GILTI”) and Subpart F income primarily generated from earnings in Canada and the United Kingdom (“UK”). For the three months ended March 31, 2020, the Company recorded income tax benefit of $(8) million on pre-tax loss of $(96) million, or an effective tax rate of 8.9%. The effective tax rate on the pre-tax loss was lower than the U.S. Statutory rate of 21% primarily as a result of income earned in jurisdictions with tax rates higher than the U.S. and tax expense related to uncertain tax positions, which was partially offset by valuation allowance releases in various jurisdictions.
