Income Tax Disclosure [Abstract]  
Income Taxes Income TaxesThe Company's effective tax rates were 8.7% and 21.9% for the three months ended September 30, 2021 and 2020, respectively, and 10.1% and 12.1% for the nine months ended September 30, 2021 and 2020, respectively. The Company has computed the provision for income taxes based on the estimated annual effective tax rate and the application of discrete items, if any, in the applicable period. The decrease in the effective tax rates in 2021 compared to the same period in 2020 was primarily due to an $8.6 million tax expense related to a U.S. entity to foreign entity intra-company asset sale recorded in the third quarter of 2020 that did not reoccur in 2021. This decrease was partially offset by an increased proportion of the Company's income generated in higher tax jurisdictions as a result of the payment of make-whole premiums related to the termination of certain institutional notes in the second and third quarters of 2021.
