Income Tax Disclosure [Abstract]
Income Taxes	Note 15. Income Taxes As of the first quarter of 2019, our estimated annual effective tax rate, which excludes discrete tax impacts, was 25.9%. This reflected the impact of unfavorable foreign provisions under U.S. tax laws and our tax related to earnings from equity method investments (which are reported separately on our statement of earnings and thus not included in earnings before income taxes), partially offset by favorable impacts from the mix of pre-tax income in various non-U.S. jurisdictions. Our effective tax rate for the three months ended March 31, 2019 of 19.4% was favorably impacted by discrete net tax benefits of $63 million, primarily driven by $60 million of benefit from the release of liabilities for uncertain tax positions due to expirations of statutes of limitations and audit settlements in several jurisdictions. As of the first quarter of 2018, our estimated annual effective tax rate, which excluded discrete tax impacts, was 22.5%. This reflected our tax related to earnings from equity method investments (which are reported separately on our statement of earnings and thus not included in earnings before income taxes), partially offset by favorable impacts from the mix of pre-tax income in various non-U.S. jurisdictions. Our effective tax rate for the three months ended March 31, 2018 of 29.1% was unfavorably impacted by net discrete tax expense of $73 million, primarily driven by $94 million of additional transition tax liability recognized as an adjustment to the prior provisional estimate, partially offset by an $18 million benefit from Argentinean refund claim.
