Income Tax Disclosure [Abstract]
Income Taxes	Income TaxesThe Company is subject to U.S. federal, state, and foreign income taxes. The Company's effective tax rate was 17.4% and 2.4% for the three months ended June 30, 2021 and 2020, respectively, and 15.8% and 4.1% for the six months ended June 30, 2021 and 2020, respectively. The Company's effective tax rate for the three and six months ended June 30, 2021 was positively impacted, compared to the U.S. federal statutory rate, primarily by income earned in foreign jurisdictions with tax rates lower than the U.S. federal statutory rate and federal tax credits for research activities. In addition, the effective tax rate for the six months ended June 30, 2021 was positively impacted by the reversal of liabilities related to uncertain tax positions. During the six months ended June 30, 2021, we reduced the amount of liabilities for uncertain tax positions related to the Company’s federal income tax returns for 2015 and 2016, and these audits are effectively settled. The Company's federal income tax returns for 2017 and 2018 are currently under audit by the Internal Revenue Service ("IRS"). The Company's effective tax rate for the three and six months ended June 30, 2020 was positively impacted, compared to the U.S. federal statutory rate, primarily by stock-based compensation, and, to a lesser extent, income earned in foreign jurisdictions with tax rates lower than the U.S. federal statutory rate and federal tax credits for research activities.
