Income Tax Disclosure [Abstract]
Taxes	Taxes We are subject to U.S. federal income tax and various state, local, and international income taxes in numerous jurisdictions. The differences between our effective tax rate and the U.S. federal statutory rate of 21% generally result from various factors, including the geographical distribution of taxable income, tax credits, contingency reserves for uncertain tax positions, and permanent differences between the book and tax treatment of certain items. Additionally, the amount of income taxes paid is subject to our interpretation of applicable tax laws in the jurisdictions in which we file. For the three and nine months ended September 30, 2020, our effective tax rate is lower than the U.S. federal statutory rate of 21% due to the net impact of the geographical distribution of our earnings, the application of the global intangible low-taxed income (“GILTI”) provisions that were implemented with the Tax Cuts and Jobs Act (the “Act”) that was passed on December 22, 2017, as well as executive compensation that is nondeductible under Internal Revenue Code ("IRC") Section 162(m) as a result of the IPO. On July 27, 2015, the U.S. Tax Court ("Tax Court") issued an opinion in Altera Corp. ("Altera") v. Commissioner ("Tax Court Opinion"), which concluded that related parties in a cost sharing arrangement are not required to share expenses related to share-based compensation. The Tax Court Opinion was appealed by the Commissioner to the Ninth Circuit Court of Appeals ("Ninth Circuit"). On June 7, 2019, a three-judge panel from the Ninth Circuit issued an opinion that reversed the Tax Court Opinion. On July 22, 2019, the taxpayer requested a rehearing before the full Ninth Circuit, which the Ninth Circuit subsequently denied. On February 10, 2020, Altera submitted a petition for writ of certiorari to the U.S. Supreme Court. On June 22, 2020, the U.S. Supreme Court denied Altera’s petition for writ of certiorari and will not review the Ninth Circuit’s June 7, 2019 decision that upheld the inclusion of share-based compensation in a cost sharing arrangement. Given the U.S. Supreme Court’s denial of the petition for writ of certiorari, we believe it is appropriate to record the financial statement impact of including share-based compensation in historical cost sharing payments discretely in the nine month period ending September 30, 2020 for years prior to 2020. The aggregate income tax impact related to the Altera decision is less than $1.0 million. If, at a future date, Altera secured a favorable ruling from the U.S. Supreme Court, we would re-evaluate the decision to record an income tax benefit at that time. On March 27, 2020, the Coronavirus Aid, Relief and Economic Security (“CARES”) Act was enacted and signed into law in response to the COVID-19 pandemic. The CARES Act contains modifications on the limitation of business interest for tax years beginning in 2019 and 2020. The modifications to Section 163(j) of the Internal Revenue Code increase the allowable business interest deduction from 30% of adjusted taxable income to 50% of adjusted taxable income. This modification significantly increases our allowable interest expense deduction resulting in less utilization of prior year net operating losses in that year. The change in the interest expense limitation pursuant to the CARES Act did not have an impact on the three or nine months ended September 30, 2020 as it is not expected to impact our net deferred tax liability for 2020. As a result of the CARES Act, it is anticipated that we will fully deduct interest expense incurred in 2020 and may be able to deduct previously disallowed interest expense carrying forward from 2018.
