Income Tax Disclosure [Abstract]
Income Taxes	Income Taxes The effective tax rate differs from the statutory U.S. federal income tax rate of 21% primarily due to foreign income tax and the valuation allowance against our domestic deferred tax assets. The Company recorded an income tax benefit of $1.0 million for the three months ended March 31, 2018 and an income tax provision of $1.2 million for the three months ended March 31, 2017. The income tax benefit in the first quarter of 2018 is primarily related to the recognition of a tax holiday granted by the Swiss government for taxes on income generated by the Company’s Swiss subsidiary, which was retroactive to the beginning of 2017. The provision in the first quarter of 2017 is primarily related to taxes on income generated by the Company’s Swiss subsidiary, for which the full statutory tax rate applied. On December 22, 2017, the President of the United States signed into law the Tax Cuts and Jobs Act. The legislation significantly changes U.S. tax law by, among other things, reducing the US federal corporate tax rate from 35% to 21%, implementing a territorial tax system and imposing a repatriation tax on deemed repatriated earnings of foreign subsidiaries. Pursuant to ASU No. 2018-05, given the amount and complexity of the changes in the tax law resulting from the tax legislation, the Company has not finalized the accounting for the income tax effects of the tax legislation. This includes the provisional amounts recorded related to the transition tax and the remeasurement of deferred taxes. The impact of the tax legislation may differ from this estimate, during the one-year measurement period due to, among other things, further refinement of the Company’s calculations, changes in interpretations and assumptions the Company has made, guidance that may be issued and actions the Company may take as a result of the tax legislation. The Company is still analyzing certain aspects of the Act and refining its calculations, which could potentially affect the analysis of the Company’s deferred tax assets and liabilities and its historical foreign earnings and profits as well as potential correlative adjustments. Any subsequent adjustment is expected to be offset by a change in valuation allowance and have no impact on the Company’s financial position or results of operations. As of March 31, 2018, the Company has a cumulative valuation allowance recorded offsetting its worldwide net deferred tax assets of $61.4 million, of which the significant majority represents the valuation allowance on its U.S. net deferred tax asset. The Company has established a valuation allowance against its U.S. federal and state deferred tax assets due to the uncertainty surrounding the realization of such assets. Management periodically evaluates the recoverability of the deferred tax assets and at such time as it is determined that it is more likely than not that U.S. deferred tax assets are realizable, the valuation allowance will be reduced accordingly. Any such release would result in recording a tax benefit that would increase net income in the period the valuation is released. During the three months ended March 31, 2018, the Company reduced its net deferred tax liabilities by $0.4 million to record the impact of the new tax holiday granted by the Swiss government. The Company records taxes on the undistributed earnings of foreign subsidiaries unless the subsidiaries’ earnings are considered indefinitely reinvested outside of the U.S. As of March 31, 2018, the Company has recorded a $4.9 million deferred tax liability for Swiss withholding taxes associated with $97.6 million of undistributed earnings of its Swiss subsidiary that are no longer considered indefinitely reinvested. Pursuant to discussions with tax authorities, the Company intends to repatriate $10.0 million in Swiss accumulated earnings each year for approximately the next 8 years in order to reduce outstanding amounts owed to its Swiss subsidiary; the Company intends to declare each annual amount as a dividend and pay a 5% withholding tax at the time such dividends are declared.
