Income Tax Disclosure [Abstract]
Income Taxes	Income Taxes The Company's effective tax rate for the third quarter of 2017 was 14.4% and differs from the U.S. federal statutory rate of 35% primarily due to a 6.6% benefit associated with the reduction of exit taxes related to our European reorganization, additional manufacturing deduction benefits and the release of valuation allowance on foreign losses. The Company's effective tax rate for the third quarter of 2016 of 30.1% differs from the U.S. federal statutory rate of 35% primarily due to profitability in more favorable tax jurisdictions and benefits associated with U.S. tax credits for research and development and the manufacturing deduction. The Company's effective tax rate for the nine months ended September 30, 2017 was 9.6% and differs from the U.S. federal statutory rate of 35% primarily due to a significant tax benefit of approximately 10.5% related to certain share-based payments related to the adoption of ASU 2016-09 as well as a 3.8% benefit associated with the reduction of exit taxes related to our European reorganization, additional manufacturing deduction benefits and the release of a valuation allowance on foreign losses. The effective tax rate for the nine months ended September 30, 2016 was 36.0%, inclusive of 3.3% associated with exit taxes related to our European reorganization. The 36.0% rate for the nine month period of 2016 differs from the U.S. federal statutory rate of 35% primarily due to the exit taxes discussed above, partially offset by profitability in more favorable tax jurisdictions and benefits associated with U.S. tax credits for research and development and the manufacturing deduction. At September 30, 2017, the Company had a gross liability for unrecognized tax benefits of $15.4 million. The Company has recognized tax benefits associated with these liabilities of $6.8 million at September 30, 2017. The gross liability includes amounts associated with prior period foreign tax exposure. The Company recognizes interest related to unrecognized tax benefits in interest expense and penalties in operating expenses. The Company's liability for accrued interest related to uncertain tax positions was $1.8 million at September 30, 2017.
