Income Tax Disclosure [Abstract]
Income Taxes	Income Taxes The Company recorded a net income tax expense of approximately $0.9 million and $0.5 million for the three months ended June 30, 2019 and 2018, respectively. The net income tax expense recorded during the three months ended June 30, 2019 is primarily related to the mix of earnings between the US and Germany, the estimated GILTI tax and the discrete tax impact of stock based compensation. The Company recorded a net income tax expense of approximately $1.2 million and $0.3 million for the six months ended June 30, 2019 and 2018, respectively. The net income tax expense recorded during the six months ended June 30, 2019 is primarily related to the mix of earnings between the US and Germany and the estimated GILTI tax, partially offset by discrete tax benefits related to an excess benefit on stock-based compensation. For the six months ended June 30, 2019, the Company’s effective tax rate (“ETR”) from operations is 25.6%, compared to 1.0% for the six months ended June 30, 2018. The difference between the Company’s ETR and the current U.S. statutory rate of 21%, as well as the difference in the ETR for the six months ended June 30, 2019 compared to the six months ended June 30, 2018, are primarily related to permanent addback items, the difference in tax rates between the U.S. and Germany, the discrete tax impact of stock-based compensation and income during the six months ended June 30, 2019 as opposed to loss during the six months ended June 30, 2018. As of each reporting date, management considers new evidence, both positive and negative, that could affect its view of the future realization of deferred tax assets (primarily federal and state net operating losses (“NOLs”). As of June 30, 2019 and December 31, 2018, the Company has a valuation allowance related to acquired state NOLs that the Company believes it is not more likely than not will be realized. During the three and six months ended June 30, 2019 and 2018, the Company had no material changes in uncertain tax positions.
