Income Tax Disclosure [Abstract]
Income Taxes	Income Taxes Our effective tax rate for the third quarter and first nine months of 2020 was 0.9% and (9.0)%, respectively, compared to the statutory rate of 21%, largely due to the favorable impact of research credits. In the first nine months of 2020, we incurred special charges and an inventory charge in a non-U.S. jurisdiction where tax benefits cannot be realized, which were partially offset by a $14 million benefit recognized upon the release of a valuation allowance in a non-U.S. jurisdiction. These items had a more significant impact on the effective tax rate due to the lower income before income taxes for the period. For the third quarter and first nine months of 2019 our effective tax rate was 8.7% and 15.8%, respectively. In the third quarter and first nine months of 2019, the effective tax rate was lower than the U.S. federal statutory tax rate of 21%, primarily due to $41 million and $53 million, respectively, in benefits recognized for additional research credits related to prior years. On October 19, 2020, we entered into a closing agreement with a tax authority related to an audit settlement with respect to certain state income tax returns. As a result, we will recognize a reduction of unrecognized tax benefits that is expected to reduce our tax expense by approximately $40 million to $50 million in the fourth quarter of 2020.
