Income Tax Disclosure [Abstract]
Income Taxes	(5) Income Taxes Our effective tax rate was 2.1% for the second quarter and 16.8% for the first half of 2020, compared with 20.6% for the second quarter and 22.3% for the first half of 2019. The 2020 tax rates were favorably impacted by $133 million from the reduction of a valuation allowance on certain foreign tax loss carryforwards due to operational changes which impacted the determination of the realizability of the deferred tax asset in that jurisdiction. The 2020 tax rates were negatively impacted by decreased earnings in certain non-U.S. jurisdictions. The 2019 tax rates were favorably impacted by the TCJA, which resulted in an approximate $60 million tax benefit from accelerated deductions claimed on our 2018 tax return filed in 2019.

The entire disclosure for income taxes. Disclosures may include net deferred tax liability or asset recognized in an enterprise's statement of financial position, net change during the year in the total valuation allowance, approximate tax effect of each type of temporary difference and carryforward that gives rise to a significant portion of deferred tax liabilities and deferred tax assets, utilization of a tax carryback, and tax uncertainties information.
