Income Tax Disclosure [Abstract]
Income Taxes	Income Taxes We consider new evidence (both positive and negative) at each reporting date that could affect our view of the future realization of deferred tax assets. Based upon the evaluation of all available evidence, and considering the projected U.S. pre-tax losses for 2021, we maintain a valuation allowance for certain of our U.S. operations as of June 30, 2021. We also maintain other valuation allowances for certain non-U.S. jurisdictions with cumulative losses. Our effective income tax rates were 7% and 10% for the three and six months ended June 30, 2021, respectively, and (2)% for both of the three and six months ended June 30, 2020, and were determined using an estimated annual effective tax rate after considering any discrete items for such periods. Our effective tax rate differs from the U.S. statutory rate of 21% primarily due to the aforementioned valuation allowance against certain of our U.S. and foreign net deferred tax assets. We recorded an overall tax expense in all periods due to pre-tax earnings in jurisdictions without valuation allowances, including our 19% noncontrolling interest in SciPlay. Additionally, our rate is impacted by an unfavorable adjustment for the legacy U.K. Gaming reporting unit goodwill impairment of $54 million recorded in the first quarter of 2020, which was not deductible for tax purposes. As discussed in Note 1, the COVID-19 disruptions significantly impacted certain segments of our business during 2020 and through the first half of 2021. We considered the COVID-19 disruptions in our ability to realize deferred tax assets in the future and determined that such conditions did not change our overall valuation allowance positions. Additionally, we continue to monitor and evaluate the tax implications resulting from any existing and forthcoming legislation passed in response to COVID-19 in the federal, state, and foreign jurisdictions where we have an income tax presence.
