Income Tax Disclosure [Abstract]
Income Taxes	Income TaxesThe Company's effective income tax rate was 23.5% for the three months ended September 30, 2021, compared to 21.8% for the same three month period in 2020. The effective income tax rate was 24.8% for the nine months ended September 30, 2021, compared to 105.4% for the same period in 2020. For the three months ended September 30, 2021, the rate increase is primarily due to income mix shifts and statute related adjustments. For the nine months ended September 30, 2021, the rate decrease is primarily due to the non-deductible goodwill impairment charge that occurred in 2020. In addition, during the second quarter of 2021, the United Kingdom enacted legislation raising its corporate tax rate from 19% to 25% effective April 2023. Accordingly, the Company remeasured its deferred tax assets and liabilities as of June 30, 2021
