Income Tax Disclosure [Abstract]
Income Taxes	Income Taxes The Company calculates its interim income tax provision in accordance with Accounting Standards Codification (“ASC”) 270, Interim Reporting, and ASC 740, Accounting for Income Taxes (together, “ASC 740”). At the end of each interim period, the Company estimates its annual effective tax rate and applies that rate to its ordinary quarterly earnings to calculate the tax related to ordinary income. The tax effects for other items that are excluded from ordinary income are discretely calculated and recognized in the period in which they occur. The Company recognized income tax provision of $12.5 million for the three months ended June 30, 2020 and income tax benefit of $0.7 million for the three months ended June 30, 2019. The Company’s 16% effective tax rate for the three months ended June 30, 2020 and -125% effective tax rate for the three months ended June 30, 2019 differed from the federal statutory rate of 21% primarily due to the discrete impact of excess tax deductions from stock-based compensation, the benefit from research and development (“R&D”) credits and the benefit from corporate deductions attributable to Foreign Derived Intangible Income (“FDII”). The Company recognized income tax expense of $21.1 million and $1.0 million for the six months ended June 30, 2020 and 2019, respectively, which represents an effective tax rate of 16% and 4%, respectively. The Company’s 16% effective tax rate for the six months ended June 30, 2020 differed from the federal statutory rate of 21% primarily due to the tax benefit recorded for excess tax benefits of stock-based compensation, the benefit from R&D credits and corporate deductions attributable to FDII. The Company is subject to periodic audits by domestic and foreign tax authorities. Due to the carryforward of unutilized credits, the Company’s federal tax years from 2009 and forward are subject to examination by the U.S. authorities. The Company’s state and foreign tax years for 2001 and forward are subject to examination by applicable tax authorities. The Company believes that it has appropriate support for the income tax positions taken on its tax returns and that its accruals for tax liabilities are adequate for all open years based on an assessment of many factors, including past experience and interpretations of tax laws applied to the facts of each matter. The Coronavirus Aid, Relief, and Economic Security Act (CARES Act) was enacted on March 27, 2020. The CARES Act includes, among other things, refundable payroll tax credits, deferment of employer side social security payments and technical amendments regarding the income tax depreciation of qualified improvement property placed in service after December 31, 2017. These amendments allow for retroactive accelerated income tax depreciation on certain of our leasehold improvement assets. We are currently assessing the impact of these provisions to our financial statements.
