Income Tax Disclosure [Abstract]  
Income Tax Disclosure [Text Block] INCOME TAXES
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, 2021 were 22% and 16%, respectively. The effective tax rates for the three and nine months ended September 30, 2020 were 28% and (60)%, respectively. The difference between the Company’s effective tax rates for the 2021 and 2020 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.
For the three and nine months ended September 30, 2021, the Company recorded discrete tax benefit of approximately $96 million ($44 million net of NCI) associated with the release of valuation allowance at one of our Brazilian subsidiaries.
For the nine months ended September 30, 2020, the Company recognized approximately $11 million of discrete tax benefit from the impact of foreign currency devaluation in Mexico.
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 losses primarily associated with the impairment of long-lived assets. Also for the nine months ended September 30, 2020, the Company 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.
