Income Tax Disclosure [Abstract]
Income Taxes	10. Income Taxes During the three and nine months ended September 30, 2019, the Company recorded an income tax provision of $0.3 million and $0.4 million, respectively, representing an effective tax rate of 0.2% and 1.2%, respectively. During the three and nine months ended September 30, 2018, the Company recorded an income tax provision of $0.1 million and $0.3 million, respectively, representing an effective tax rate of -0.3% and -0.3%, respectively. The income tax provision is primarily attributable to the year-to-date pre-tax income earned by the Company’s U.S. subsidiary. The difference in the statutory tax rate and effective tax rate is primarily a result of the jurisdictional mix of earnings and losses that are not benefited. The Company maintains a valuation allowance against certain deferred tax assets that are not more-likely-than-not realizable. As a result, the Company has not recognized a tax benefit related to losses generated in Switzerland in the current periods.
