Income Tax Disclosure [Abstract]
Income Taxes	Note 13 – Income Taxes Within our Condensed Consolidated Statements of Comprehensive Income, we recorded Income tax expense on continuing operations of $2 million and $301 million for the three months ended June 30, 2020 and 2019, respectively, and $308 million and $596 million for the six months ended June 30, 2020 and 2019, respectively. The change for the three and six months ended June 30, 2020 was primarily from lower income before income taxes. The effective tax rate from continuing operations was negative 0.7% for the three months ended June 30, 2020 and 24.4% for the three months ended June 30, 2019, and 29.4% and 24.4% for the six months ended June 30, 2020 and 2019, respectively. The negative effective income tax rate for the three months ended June 30, 2020, due to a small pre-tax loss, was primarily attributable to expenses that are not deductible for income tax purposes, including our Layer3 goodwill impairment and certain Merger-related costs. The increase in the effective income tax rate for the six months ended June 30, 2020, was primarily due to a reduction in income before income taxes and increase in expenses that are not deductible for income tax purposes, primarily related to our Layer3 goodwill impairment and certain Merger-related costs. As a result of the Merger, the Company acquired an estimated $1.1 billion of additional deferred tax assets for which a valuation allowance reserve is deemed to be necessary, plus an estimated $534 million in additional uncertain tax benefit reserves. Due to the size and complexity of the Merger, our estimate of these amounts is preliminary and is subject to finalization and adjustment, which could be material, during the measurement period of up to one year from the Merger date. During the measurement period, we will adjust these amounts if new information is obtained about facts or circumstances that existed as of the acquisition date that, if known, would have changed these amounts. See Note 2 - Business Combination for further information.
