Income Tax Disclosure [Abstract]
Income taxes	Income taxesThe Company's effective tax rate was 18.9% and 23.2% for the three months ended September 30, 2021 and 2020, respectively, and 20.0% and 24.3% for the nine months ended September 30, 2021 and 2020, respectively. The decrease in the Company's effective tax rate for the three and nine months ended September 30, 2021 compared to the prior year is primarily due to an increase in tax benefits from stock-based compensation deductions in 2021 as well as a reduction in nondeductible advocacy expenses in 2021.
