Income Tax Disclosure [Abstract]
Income Taxes	Income Taxes The provision for income taxes for the three months ended September 30, 2020 and 2019 was a benefit of $2.8 million and an expense of $11.7 million, respectively. The provision for income taxes for the nine months ended September 30, 2020 was an expense of $22.8 million compared to a benefit of $0.4 million for the nine months ended September 30, 2019. The effective income tax rate was a benefit of 19.7% and an expense of 22.1% for the three months ended September 30, 2020 and 2019, respectively. The effective income tax rate was an expense of 13.4% for the nine months ended September 30, 2020 compared to a benefit of 0.3% for the nine months ended September 30, 2019. The year to date results for both years include material benefits from intercompany sales of certain intellectual property. The three and nine months results for both years also include movements in unrecognized tax benefits as well as changes in estimated geographical mix of earnings. The changes in effective tax rates are largely attributable to the differences in the relative impacts of these items period over period. The Company completed intercompany sales of certain intellectual property in both 2020 and 2019. As a result, the Company recorded tax benefits of approximately $28.3 million and $38.1 million during the nine months ended September 30, 2020 and 2019, respectively. These benefits represent the value of future tax deductions for amortization of the assets in the acquiring jurisdiction. In July 2020, the Company completed an intercompany contribution of a significant amount of intellectual property. The Company’s intellectual property footprint continues to evolve and may result in tax rate volatility in the future. The Company had gross unrecognized tax benefits of $118.5 million on September 30, 2020 and $102.8 million on December 31, 2019. It is reasonably possible that gross unrecognized tax benefits will decrease by approximately $9.9 million within the next twelve months due to the anticipated closure of audits and the expiration of certain statutes of limitation.
