Income Tax Disclosure [Abstract]
Income Tax Disclosure [Text Block]	The Company’s provision for income taxes is based on the estimated annual effective tax rate, plus discrete items. The effective tax rates for the three and nine months ended September 30, 2020 were 28% and (60)%, respectively. The effective tax rates for the three and nine months ended September 30, 2019 were 31% and 34%, respectively. The difference between the Company’s effective tax rates for the 2020 and 2019 periods and the U.S. statutory tax rate of 21% related primarily to U.S. taxes on foreign earnings, foreign tax rate differentials, the impacts of foreign currency fluctuations at certain foreign subsidiaries, nondeductible expenses, and valuation allowance. The impact of foreign currency devaluation in Mexico was approximately $11 million of discrete tax benefit for the nine months ended September 30, 2020. The impact of foreign currency devaluation in Argentina was approximately $11 million and $17 million of discrete tax expense for the three and nine month periods ended September 30, 2019, respectively. For the three and nine months ended September 30, 2020, the Company recognized discrete tax benefit of approximately $28 million and $20 million, respectively, on the Company’s investment in Guacolda for equity earnings losses primarily associated with the impairment of long-lived assets. For the nine months ended September 30, 2020, the Company also recognized discrete tax expense of $21 million as a result of incremental capitalized interest in Chile and discrete tax expense of approximately $25 million as a result of incremental deferred taxes relating to DPL.
