Income Tax Disclosure [Abstract] |
Income Taxes | Income Taxes Income tax expense was $97 million and $56 million for the three months ended June 30, 2021 and 2020, respectively. The effective tax rate, expressed by calculating the income tax expense as a percentage of Income before income taxes, was 26.2% and 22.9% for the three months ended June 30, 2021 and 2020, respectively. The effective tax rate for the three months ended June 30, 2021 differed from the US federal statutory rate of 21.0% primarily due to state and local income taxes and a discrete deferred tax expense as a result of an increase in the UK corporate tax rate effective in 2023, partially offset by excess tax benefits on equity-based compensation. The effective tax rate for the three months ended June 30, 2020 differed from the US federal statutory rate of 21.0% primarily due to state and local income taxes, partially offset by excess tax benefits on equity-based compensation.
